Pediatric concussion is one of those rare phenomena in which we may be witnessing its emergence and clarification in a generation. When I was serving as the game doctor for our local high school football team in the 1970s, I and many other physicians had a very simplistic view of concussion. If the patient never lost conscious and had a reasonably intact short-term memory, we didn’t seriously entertain concussion as a diagnosis. “What’s the score and who is the president?” Were my favorite screening questions.

Obviously, we were underdiagnosing and mismanaging concussion. In part thanks to some high-profile athletes who suffered multiple concussions and eventually chronic traumatic encephalopathy (CTE) physicians began to realize that they should be looking more closely at children who sustained a head injury. The diagnostic criteria were expanded to include any injury that even temporarily effected brain function.

With the new appreciation for the risk of multiple concussions, the focus broadened to include the question of when is it safe for the athlete to return to competition. What signs or symptoms can the patient offer us so we can be sure his or her brain is sufficiently recovered? Here we stepped off into a deep abyss of ignorance. Fortunately, it became obvious fairly quickly that imaging studies weren’t going to help us, as they were invariably normal or at least didn’t tell us anything that wasn’t obvious on a physical exam.

If the patient had a headache, complained of dizziness, or manifested amnesia, monitoring the patient was fairly straightforward. But, in the absence of symptoms and no obvious way to determine the pace of recovery of an organ we couldn’t visualize, clinicians were pulling criteria and time tables out of thin air. Guessing that the concussed brain was in some ways like a torn muscle or overstretched tendon, “brain rest” was often suggested. So no TV, no reading, and certainly none of the cerebral challenging activity of school. Fortunately, we don’t hear much about the notion of brain rest anymore and there is at least one study that suggests that patients kept home from school recover more slowly.

But there remains a significant number of patients who have persistent symptoms and are unable to resume their usual activities, including school and sports. Sometimes they describe headache or dizziness but often they complain of a vague mental unwellness. “Brain fog,” a term that has emerged in the wake of the COVID pandemic, might be an apt descriptor. Management of these slow recoverers has been a challenge.

However, two recent articles in the journal Pediatrics may provide some clarity and offer guidance in their management. In a study coming from the psychology department at Georgia State University, researchers reported that they have been able to find “no evidence of clinical meaningful differences in IQ after pediatric concussion.” In their words there is “strong evidence against reduced intelligence in the first few weeks to month after pediatric concussion.”

While their findings may simply toss the IQ onto the pile of worthless measures of healing, a companion commentary by Talin Babikian, PhD, a psychologist at the Semel Institute for Neuroscience and Human Behavior at UCLA, provides a more nuanced interpretation. He writes that if we are looking for an explanation when a patient’s recovery is taking longer than we might expect we need to look beyond some structural damage. Maybe the patient has a previously undiagnosed premorbid condition effecting his or her intellectual, cognitive, or learning abilities. Could the stall in improvement be the result of other symptoms? Here fatigue and sleep deprivation may be the culprits. Could some underlying emotional factor such as anxiety or depression be the problem? For example, I have seen patients whose fear of re-injury has prevented their return to full function. And, finally, the patient may be avoiding a “nonpreferred or challenging situation” unrelated to the injury.

In other words, the concussion may simply be the most obvious rip in a fabric that was already frayed and under stress. This kind of broad holistic (a word I usually like to avoid) thinking may be what is lacking as we struggle to understand other mysterious and chronic conditions such as Lyme disease and chronic fatigue syndrome.

While these two papers help provide some clarity in the management of pediatric concussion, what they fail to address is the bigger question of the relationship between head injury and CTE. The answers to that conundrum are enshrouded in a mix of politics and publicity that I doubt will clear in the near future.

Almonds and almond oil are known to exhibit anti-inflammatory, antihepatotoxicity, and immunity-boosting activity.1 The seed from the deciduous almond tree (Oleum amygdalae), which is native to Iran and parts of the Levant, almonds contain copious amounts of phenols and polyphenols, fatty acids, and vitamin E, all of which are known to exert antioxidant activity.2-5 These seeds have been found to have a substantial impact on serum lipids.4 Emollient and sclerosant characteristics have also been linked to almond oil, which has been found to ameliorate complexion and skin tone.5 Significantly, in vitro and in vivo studies have shown that UVB-induced photoaging can be attenuated through the use of almond oil and almond skin extract.2 Further, in traditional Chinese Medicine, Ayurveda, and ancient Greco-Persian medicine, almond oil was used to treat cutaneous conditions, including eczema and psoriasis.1The focus of this column is to provide an update on the use of almonds and almond oil for skincare since covering the topic in July 2014.

Antiphotoaging activity

In 2019, Foolad and Vaughn conducted a prospective, investigator-blind, randomized controlled trial to determine the effects of almond consumption on facial sebum production and wrinkles. Participants (28 postmenopausal women with Fitzpatrick skin types I and II completed the study) consumed 20% of their daily energy intake in almonds or a calorie-matched snack over 16 weeks through the UC Davis Dermatology Clinic. Photographic analysis revealed that the almond group experienced significantly diminished wrinkle severity, compared with the control group. The investigators concluded that daily almond consumption has the potential to decrease wrinkle severity in postmenopausal women and that almonds may confer natural antiaging effects.4

In a similar investigation 2 years later, Rybak et al. reported on a prospective, randomized controlled study to ascertain the effects of almond consumption on photoaging in postmenopausal women with Fitzpatrick skin types I or II who obtained 20% of their daily energy consumption via almonds or a calorie-matched snack for 24 weeks. Results demonstrated significant effects conferred by almond consumption, with average wrinkle severity substantially diminished in the almond group at weeks 16 (by 15%) and 24 (by 16%), compared with baseline. In addition, facial pigment intensity was reduced by 20% in the almond group by week 16 and this was maintained through the end of the study. Further, sebum excretion was higher in the control group. The investigators concluded that the daily consumption of almonds may have the potential to enhance protection against photoaging, particularly in terms of facial wrinkles and pigment intensity, in postmenopausal women.3

Later in 2021, Li et al. conducted a study in 39 healthy Asian women (18-45 years old) with Fitzpatrick skin types II to IV to investigate the effects of almond consumption on UVB resistance. The researchers randomized participants to eat either 1.5 oz of almonds or 1.8 oz of pretzels daily for 12 weeks. Results showed that the minimal erythema dose was higher in the almond group as compared with the control group. No differences were observed in hydration, melanin, roughness, or sebum on facial skin. The authors concluded that daily oral almond intake may improve photoprotection by raising the minimal erythema dose.2

In a 2022 review on the cutaneous benefits of sweet almond, evening primrose, and jojoba oils, Blaak and Staib noted that all three have been used for hundreds if not thousands of years in traditional medicine to treat various conditions, including skin disorders. Further, they concluded that the longstanding uses of these oils has been borne out by contemporary data, which reveal cutaneous benefits for adult and young skin, particularly in bolstering stratum corneum integrity, recovery, and lipid ratio.6

Later that year, Sanju et al., reporting on the development and assessment of a broad-spectrum polyherbal sunscreen delivered through solid lipid nanoparticles, noted that almond oil was among the natural ingredients used because of its photoprotective characteristics. Overall, the sunscreen formulation, Safranal, was found to impart robust protection against UV radiation.7

 

 

Wound healing

In 2020, Borzou et al. conducted a single-blind randomized clinical trial to ascertain the impact of topical almond oil in preventing pressure injuries. Data collection occurred over 8 months in a hospital setting, with 108 patients randomly assigned to receive almond oil, placebo (liquid paraffin), or the control (standard of care). The researchers found that topically applied almond oil was linked to a lower incidence of pressure injuries, and they arose later in the study as compared with those injuries in the groups receiving paraffin or standard of care. Pressure injury incidence was 5.6% in the almond oil group, 13.9% in the placebo group, and 25.1% in the control group.8

That same year, Caglar et al. completed a randomized controlled trial in 90 preterm infants to assess the effects of sunflower seed oil and almond oil on the stratum corneum. Infants were randomly selected for treatment with either oil or control. A nurse researcher applied oils to the whole body except for the head and face four times daily for 5 days. Investigators determined that stratum corneum hydration was better in the oil groups as compared with control, with no difference found between sunflower seed and almond oils.9

Eczema, hand dermatitis, and striae

In 2018, Simon et al. performed a randomized, double-blind study to determine the short- and long-term effects of two emollients on pruritus and skin restoration in xerotic eczema. The emollients contained lactic acid and refined almond oil, with one also including polidocanol. Both emollients were effective in reducing the severity of itching, with skin moisture and lipid content found to have risen after the initial administration and yielding steady improvement over 2 weeks.10

Earlier that year, Zeichner et al. found that the use of an OTC sweet almond oil, rich in fatty acids and a standard-bearing treatment for eczema and psoriasis for centuries, was effective in treating hand dermatitis. Specifically, the moisturizer, which contained 7% sweet almond oil and 2% colloidal oatmeal, was identified as safe and effective in resolving moderate to severe hand dermatitis.11

Some studies have also shown almond oil to be effective against striae gravidarum. Hajhashemi et al. conducted a double-blind clinical trial in 160 nulliparous women to compare the effects of aloe vera gel and sweet almond oil on striae gravidarum in 2018. Volunteers were randomly assigned to one of three case groups (Aloe vera, sweet almond oil, or base cream) who received topical treatment on the abdomen, or the fourth group, which received no treatment. Results showed that both treatment creams were effective in decreasing erythema and the pruritus associated with striae as well as in preventing their expansion.12 Previously, Tashan and Kafkasli showed in a nonrandomized study that massage with bitter almond oil may diminish the visibility of present striae gravidarum and prevent the emergence of new striae.13

Conclusion

Almonds and almond oil have been used as food and in traditional medical practices dating back several centuries. In the last decade, intriguing results have emerged regarding the effects of almond consumption or topical almond oil administration on skin health. While much more research is necessary, the recent data seem to support the traditional uses of this tree seed for dermatologic purposes.

In 2019, Foolad and Vaughn conducted a prospective, investigator-blind, randomized controlled trial to determine the effects of almond consumption on facial sebum production and wrinkles. Participants (28 postmenopausal women with Fitzpatrick skin types I and II completed the study) consumed 20% of their daily energy intake in almonds or a calorie-matched snack over 16 weeks through the UC Davis Dermatology Clinic. Photographic analysis revealed that the almond group experienced significantly diminished wrinkle severity, compared with the control group. The investigators concluded that daily almond consumption has the potential to decrease wrinkle severity in postmenopausal women and that almonds may confer natural antiaging effects.4

In a similar investigation 2 years later, Rybak et al. reported on a prospective, randomized controlled study to ascertain the effects of almond consumption on photoaging in postmenopausal women with Fitzpatrick skin types I or II who obtained 20% of their daily energy consumption via almonds or a calorie-matched snack for 24 weeks. Results demonstrated significant effects conferred by almond consumption, with average wrinkle severity substantially diminished in the almond group at weeks 16 (by 15%) and 24 (by 16%), compared with baseline. In addition, facial pigment intensity was reduced by 20% in the almond group by week 16 and this was maintained through the end of the study. Further, sebum excretion was higher in the control group. The investigators concluded that the daily consumption of almonds may have the potential to enhance protection against photoaging, particularly in terms of facial wrinkles and pigment intensity, in postmenopausal women.3

Later in 2021, Li et al. conducted a study in 39 healthy Asian women (18-45 years old) with Fitzpatrick skin types II to IV to investigate the effects of almond consumption on UVB resistance. The researchers randomized participants to eat either 1.5 oz of almonds or 1.8 oz of pretzels daily for 12 weeks. Results showed that the minimal erythema dose was higher in the almond group as compared with the control group. No differences were observed in hydration, melanin, roughness, or sebum on facial skin. The authors concluded that daily oral almond intake may improve photoprotection by raising the minimal erythema dose.2

In a 2022 review on the cutaneous benefits of sweet almond, evening primrose, and jojoba oils, Blaak and Staib noted that all three have been used for hundreds if not thousands of years in traditional medicine to treat various conditions, including skin disorders. Further, they concluded that the longstanding uses of these oils has been borne out by contemporary data, which reveal cutaneous benefits for adult and young skin, particularly in bolstering stratum corneum integrity, recovery, and lipid ratio.6

Later that year, Sanju et al., reporting on the development and assessment of a broad-spectrum polyherbal sunscreen delivered through solid lipid nanoparticles, noted that almond oil was among the natural ingredients used because of its photoprotective characteristics. Overall, the sunscreen formulation, Safranal, was found to impart robust protection against UV radiation.7

 

 

Wound healing

In 2020, Borzou et al. conducted a single-blind randomized clinical trial to ascertain the impact of topical almond oil in preventing pressure injuries. Data collection occurred over 8 months in a hospital setting, with 108 patients randomly assigned to receive almond oil, placebo (liquid paraffin), or the control (standard of care). The researchers found that topically applied almond oil was linked to a lower incidence of pressure injuries, and they arose later in the study as compared with those injuries in the groups receiving paraffin or standard of care. Pressure injury incidence was 5.6% in the almond oil group, 13.9% in the placebo group, and 25.1% in the control group.8

That same year, Caglar et al. completed a randomized controlled trial in 90 preterm infants to assess the effects of sunflower seed oil and almond oil on the stratum corneum. Infants were randomly selected for treatment with either oil or control. A nurse researcher applied oils to the whole body except for the head and face four times daily for 5 days. Investigators determined that stratum corneum hydration was better in the oil groups as compared with control, with no difference found between sunflower seed and almond oils.9

Eczema, hand dermatitis, and striae

In 2018, Simon et al. performed a randomized, double-blind study to determine the short- and long-term effects of two emollients on pruritus and skin restoration in xerotic eczema. The emollients contained lactic acid and refined almond oil, with one also including polidocanol. Both emollients were effective in reducing the severity of itching, with skin moisture and lipid content found to have risen after the initial administration and yielding steady improvement over 2 weeks.10

Earlier that year, Zeichner et al. found that the use of an OTC sweet almond oil, rich in fatty acids and a standard-bearing treatment for eczema and psoriasis for centuries, was effective in treating hand dermatitis. Specifically, the moisturizer, which contained 7% sweet almond oil and 2% colloidal oatmeal, was identified as safe and effective in resolving moderate to severe hand dermatitis.11

Some studies have also shown almond oil to be effective against striae gravidarum. Hajhashemi et al. conducted a double-blind clinical trial in 160 nulliparous women to compare the effects of aloe vera gel and sweet almond oil on striae gravidarum in 2018. Volunteers were randomly assigned to one of three case groups (Aloe vera, sweet almond oil, or base cream) who received topical treatment on the abdomen, or the fourth group, which received no treatment. Results showed that both treatment creams were effective in decreasing erythema and the pruritus associated with striae as well as in preventing their expansion.12 Previously, Tashan and Kafkasli showed in a nonrandomized study that massage with bitter almond oil may diminish the visibility of present striae gravidarum and prevent the emergence of new striae.13

Conclusion

Almonds and almond oil have been used as food and in traditional medical practices dating back several centuries. In the last decade, intriguing results have emerged regarding the effects of almond consumption or topical almond oil administration on skin health. While much more research is necessary, the recent data seem to support the traditional uses of this tree seed for dermatologic purposes.

Skin has different daytime and nighttime needs, emerging circadian research suggests

Emerging research on so-called “clock genes” suggests that the human skin has different daytime and nighttime needs, according to Ava Shamban, MD.

“Paying attention to the circadian rhythm of the skin is every bit as important as moisturizing the skin,” Dr. Shamban, a dermatologist who practices in Santa Monica, Calif., said at the annual Masters of Aesthetics Symposium. “It is paramount to both your morning and evening skin regimen routine,” she added.

Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle. “These natural processes respond primarily to light and dark and affect most living things, including animals, plants, and microbes,” she said. “The circadian system is composed of peripheral circadian oscillators in many other cells, including the skin.”

The science has been around awhile, but dermatologists didn’t understand its impact until recently, she said.

In 1729, the French astronomer Jean-Jacques d’Ortous de Mairan demonstrated that mimosa leaves, which open at dawn and close at dusk, continued this cycle even when kept in darkness. In the 1970s, Seymour Benzer and Ronald Konopka showed that mutations in an unknown gene disrupted the circadian clock of fruit flies.

And in 2017, the Nobel Prize in Physiology or Medicine was awarded to Jeffrey C. Hall, Michael Rosbash, and Michael W. Young for discovering molecular mechanisms that control circadian rhythm. Using fruit flies as a model, they isolated a gene that controls the normal daily biological rhythm.

“They showed that this gene encodes a protein that accumulates in the cell during the night and is then degraded during the day, and they identified additional protein components, exposing the mechanism governing the self-sustaining clockwork inside the cell,” said Dr. Shamban.

In humans and other mammals, the primary body clock is located in the suprachiasmatic nucleus, a cluster of approximately 10,000 neurons located on either side of the midline above the optic chiasma, about 3 cm behind the eyes. Several clock genes have been identified that regulate and control transcription and translation.



“Expression of these core clock genes inside the cell influences many signaling pathways, which allows the cells to identify the time of day and perform their appropriate function,” Dr. Shamban said. “Furthermore, phosphorylation of core clock proteins leads to degradation to keep the 24-hour cycle in sync.”

Photoreceptive molecules known as opsins also appear to play a role in regulating the skin’s clock. A systematic review of 22 articles published in 2020 found that opsins are present in keratinocytes, melanocytes, dermal fibroblasts, and hair follicle cells, and they have been shown to mediate wound healing, melanogenesis, hair growth, and skin photoaging in human and nonhuman species.

“You may wonder, why does the skin respond so nicely to light?” Dr. Shamban said. “Because it contains opsins, and light exposure through opsin-regulated pathways stimulates melanin production.”

Patients can support their skin’s clock genes by understanding that skin barrier functions such as photoprotection and sebum production are increased during the day, while skin permeability processes such as DNA repair, cell proliferation, and blood flow are enhanced at night.

“Your skin has different daytime and nighttime needs,” Dr. Shamban commented. “Simply put, daytime is defense, and nighttime is offense. I think we’ve known this intuitively, but to know that there is science supporting this idea is important.”

Dr. Shamban wrote the book “Heal Your Skin: The Breakthrough Plan for Renewal” (Wiley, 2011). She disclosed that she conducts clinical trials for many pharmaceutical and device companies.

CoolSculpting remains most popular procedure for noninvasive fat removal, expert says

After fashion model Linda Evangelista filed and ultimately settled a lawsuit against Zeltiq Aesthetics in 2022 subsequent to developing paradoxical adipose hyperplasia she claimed was caused by several sessions of CoolSculpting, some aesthetic experts wondered how consumers would embrace the fat reduction procedure going forward.

The negative publicity surrounding this case “is thought to have detracted from some of the volume of it [in terms of demand], but it looks like it’s coming back again,” Omar A. Ibrahimi, MD, PhD, medical director of the Connecticut Skin Institute, Stamford, said during a presentation on noninvasive fat removal treatment options at the annual Masters of Aesthetics Symposium.

Dr. Omar A. Ibrahimi

In fact, he said, CoolSculpting accounts for an estimated 72% of noninvasive fat removal treatments performed in the United States. “By and large, there is high satisfaction with this procedure,” said Dr. Ibrahimi. “There have been about 17 million procedures done worldwide. Paradoxical adipose hyperplasia is a very rare side effect. As newer iterations of this technology have come out, I think there is an even lower incidence.”

CoolSculpting, or cryolipolysis, freezes excess fat to remove it from stubborn areas via panniculitis. The technology was developed by Dieter Manstein MD, PhD, and R. Rox Anderson, MD, at Massachusetts General Hospital and Harvard Medical School, both in Boston, and cleared by the U.S. Food and Drug Administration for noninvasive fat removal in 2010.

“If you kill a fat cell in an adult, it can’t come back,” Dr. Ibrahimi said. “When this technology first came out it was very simple. We treated an area once and were done. Now we know to treat the area multiple times, and you can treat a much larger volume in a patient during one session safely. You can bring about dramatic results, but it often takes a series of 35-minute treatment cycles and about 3 months to see clinical results. There are published studies showing that results are persisting even 10 years after treatment. This is nice, because I tell my patients, ‘if you keep up with your diet and exercise, we don’t expect the fat to come back.’ ”

Other noninvasive options for fat removal include the following:

  • Ultrasound. Options include high-intensity focused ultrasound (Liposonix) and pulsed focused ultrasound (UltraShape). Dr. Ibrahimi described these devices as “very painful, and the results were very difficult to reproduce from the initial clinical studies.”
  • Low-level light therapy. Early devices on the market include Zerona and UltraSlim. “Oftentimes these lacked any sort of histological analysis,” he said. “There was no obvious mechanism of action, and questionable efficacy.”
  • Laser. Powered by a 1060-nm laser, SculpSure can reduce fat cells safely in 25-minute treatment sessions, Dr. Ibrahimi said. Each session is delivered with one of four available applicators and involves 4 minutes of heating and the next 21 minutes alternating between heating and cooling. “You’re trying to reach a target temperature that kills fat cells,” he explained. “The beauty of having these applicators is that you can kind of customize to the individual patient; it uses contact cooling, and it’s safe for all Fitzpatrick skin types. This device results in a 10%-12% reduction in fat, so it’s clinically significant but very modest.”
 

 

A robotic version of the technology, known as the Robotic Fat Killer, is also available. So is the EON, a touchless 1064-nm laser FDA cleared for abdominal, flank, thigh, and back fat reduction. “It adapts to the body shape of the area and individual to deliver a customized treatment,” Dr. Ibrahimi said.

  • Radiofrequency. Most devices on the market, such as truSculpt and Vanquish, are powered by monopolar radiofrequency (RF) energy. “Similar to the 1060-nm laser, you can customize these treatments,” he said. “You’re treating to a target temperature. It involves 15-minute cycles, and there are clinical, histology, and ultrasound data supporting this technology.”


Dr. Ibrahimi uses truSculpt and CoolSculpting in his practice, “but sometimes you have patients who are ‘too fit’ for CoolSculpting; they don’t fit the handpiece perfectly,” he said. “That’s where having a monopolar RF or a 1060-nm laser is useful, to help you hone in on those stubborn pockets of fat.”

  • Deoxycholic acid. While not a device, deoxycholic acid (Kybella), administered subcutaneously, is approved by the FDA for improving “the appearance of moderate to severe convexity or fullness associated with submental fat” in adults. “A lot of people use it off-label on the abdomen and other stubborn areas,” Dr. Ibrahimi said. “It often requires a series of treatments. That’s the biggest limiting issue with using this technology. It works well, but compared to CoolSculpting, there is a lot of swelling and bruising, which you would expect with an injectable. Managing that down time and hand holding is difficult. But if you can get patients to buy into the downtime, [it yields] pretty impressive results.”

Dr. Ibrahimi also discussed the promise of electrical muscle stimulation for strengthening, firming, and toning muscles. The technology applies an electrical current through electrodes placed on the skin, which stimulates muscles, or through an electromagnetic field.



In a published study of 45 men and women, Dr. Ibrahimi, Anne Chapas, MD, medical director of UnionDerm in New York, and colleagues evaluated the safety and efficacy of an electrical muscle stimulation system for improving muscle strength and toning of the upper extremities.

For the treatments, they used disposable contact pads to place pairs of electrodes on the biceps and on the triceps. All patients (median age 42) received 30-minute treatments twice weekly for 2 or 3 weeks, corresponding to four or six total sessions respectively, depending on the study site. Follow-ups were conducted 30 and 90 days after treatment. They used a validated dynamometer device to measure strength at baseline, at the final treatment session, and at the post-treatment 30- and 90-day visits.

“We saw about a 40% increase in strength in the biceps and about a 30% increase in strength in the triceps,” Dr. Ibrahimi said. “Interestingly, the effect got greater at 30 and 90 days, so this is something that lingers on for quite a while.” In addition to the increase in strength, the researchers and patients noted an improvement in the appearance of the arms. He predicted that this technology “is going to play a role in functional medicine and getting injured athletes back to their sports faster.”

Dr. Ibrahimi disclosed that he is a member of the Advisory Board for Accure Acne, AbbVie, Cutera (manufacturer of truSculpt), Lutronic, Blueberry Therapeutics, Cytrellis, and Quthero. He also holds stock in many device and pharmaceutical companies (none are relevant to the treatments mentioned in this story).

In fact, he said, CoolSculpting accounts for an estimated 72% of noninvasive fat removal treatments performed in the United States. “By and large, there is high satisfaction with this procedure,” said Dr. Ibrahimi. “There have been about 17 million procedures done worldwide. Paradoxical adipose hyperplasia is a very rare side effect. As newer iterations of this technology have come out, I think there is an even lower incidence.”

CoolSculpting, or cryolipolysis, freezes excess fat to remove it from stubborn areas via panniculitis. The technology was developed by Dieter Manstein MD, PhD, and R. Rox Anderson, MD, at Massachusetts General Hospital and Harvard Medical School, both in Boston, and cleared by the U.S. Food and Drug Administration for noninvasive fat removal in 2010.

“If you kill a fat cell in an adult, it can’t come back,” Dr. Ibrahimi said. “When this technology first came out it was very simple. We treated an area once and were done. Now we know to treat the area multiple times, and you can treat a much larger volume in a patient during one session safely. You can bring about dramatic results, but it often takes a series of 35-minute treatment cycles and about 3 months to see clinical results. There are published studies showing that results are persisting even 10 years after treatment. This is nice, because I tell my patients, ‘if you keep up with your diet and exercise, we don’t expect the fat to come back.’ ”

Other noninvasive options for fat removal include the following:

  • Ultrasound. Options include high-intensity focused ultrasound (Liposonix) and pulsed focused ultrasound (UltraShape). Dr. Ibrahimi described these devices as “very painful, and the results were very difficult to reproduce from the initial clinical studies.”
  • Low-level light therapy. Early devices on the market include Zerona and UltraSlim. “Oftentimes these lacked any sort of histological analysis,” he said. “There was no obvious mechanism of action, and questionable efficacy.”
  • Laser. Powered by a 1060-nm laser, SculpSure can reduce fat cells safely in 25-minute treatment sessions, Dr. Ibrahimi said. Each session is delivered with one of four available applicators and involves 4 minutes of heating and the next 21 minutes alternating between heating and cooling. “You’re trying to reach a target temperature that kills fat cells,” he explained. “The beauty of having these applicators is that you can kind of customize to the individual patient; it uses contact cooling, and it’s safe for all Fitzpatrick skin types. This device results in a 10%-12% reduction in fat, so it’s clinically significant but very modest.”
 

 

A robotic version of the technology, known as the Robotic Fat Killer, is also available. So is the EON, a touchless 1064-nm laser FDA cleared for abdominal, flank, thigh, and back fat reduction. “It adapts to the body shape of the area and individual to deliver a customized treatment,” Dr. Ibrahimi said.

  • Radiofrequency. Most devices on the market, such as truSculpt and Vanquish, are powered by monopolar radiofrequency (RF) energy. “Similar to the 1060-nm laser, you can customize these treatments,” he said. “You’re treating to a target temperature. It involves 15-minute cycles, and there are clinical, histology, and ultrasound data supporting this technology.”


Dr. Ibrahimi uses truSculpt and CoolSculpting in his practice, “but sometimes you have patients who are ‘too fit’ for CoolSculpting; they don’t fit the handpiece perfectly,” he said. “That’s where having a monopolar RF or a 1060-nm laser is useful, to help you hone in on those stubborn pockets of fat.”

  • Deoxycholic acid. While not a device, deoxycholic acid (Kybella), administered subcutaneously, is approved by the FDA for improving “the appearance of moderate to severe convexity or fullness associated with submental fat” in adults. “A lot of people use it off-label on the abdomen and other stubborn areas,” Dr. Ibrahimi said. “It often requires a series of treatments. That’s the biggest limiting issue with using this technology. It works well, but compared to CoolSculpting, there is a lot of swelling and bruising, which you would expect with an injectable. Managing that down time and hand holding is difficult. But if you can get patients to buy into the downtime, [it yields] pretty impressive results.”

Dr. Ibrahimi also discussed the promise of electrical muscle stimulation for strengthening, firming, and toning muscles. The technology applies an electrical current through electrodes placed on the skin, which stimulates muscles, or through an electromagnetic field.



In a published study of 45 men and women, Dr. Ibrahimi, Anne Chapas, MD, medical director of UnionDerm in New York, and colleagues evaluated the safety and efficacy of an electrical muscle stimulation system for improving muscle strength and toning of the upper extremities.

For the treatments, they used disposable contact pads to place pairs of electrodes on the biceps and on the triceps. All patients (median age 42) received 30-minute treatments twice weekly for 2 or 3 weeks, corresponding to four or six total sessions respectively, depending on the study site. Follow-ups were conducted 30 and 90 days after treatment. They used a validated dynamometer device to measure strength at baseline, at the final treatment session, and at the post-treatment 30- and 90-day visits.

“We saw about a 40% increase in strength in the biceps and about a 30% increase in strength in the triceps,” Dr. Ibrahimi said. “Interestingly, the effect got greater at 30 and 90 days, so this is something that lingers on for quite a while.” In addition to the increase in strength, the researchers and patients noted an improvement in the appearance of the arms. He predicted that this technology “is going to play a role in functional medicine and getting injured athletes back to their sports faster.”

Dr. Ibrahimi disclosed that he is a member of the Advisory Board for Accure Acne, AbbVie, Cutera (manufacturer of truSculpt), Lutronic, Blueberry Therapeutics, Cytrellis, and Quthero. He also holds stock in many device and pharmaceutical companies (none are relevant to the treatments mentioned in this story).

Obesity-related cardiovascular disease deaths surging

Article Type
Changed
Thu, 09/07/2023 - 06:27

 

TOPLINE:

In contrast to an overall decline in cardiovascular mortality, obesity-related cardiovascular deaths have risen substantially in the past 2 decades, most prominently among Black women. “We observed a threefold increase in obesity-related cardiovascular age-adjusted mortality rates between 1999 and 2020,” wrote the authors.

METHODOLOGY:

Data from the U.S. population-level Multiple Cause of Death database were analyzed, including 281,135 deaths in 1999-2020 for which obesity was listed as a contributing factor.

TAKEAWAY:

  • Overall, the crude rate of all cardiovascular deaths dropped by 17.6% across all races.
  • However, age-adjusted obesity-related cardiovascular mortality tripled from 2.2/100,000 to 6.6/100,000 from 1999 to 2020, consistent across all racial groups.
  • Blacks had the highest age-adjusted obesity-related cardiovascular mortality (rising from 4.2/100,000 in 1999 to 11.6/100,000 in 2000).
  • Ischemic heart disease was the most common cardiovascular cause of death across all races, and hypertensive disease was second.
  • Age-adjusted obesity-related cardiovascular mortality was higher among Blacks (6.7/100,000) than any other racial group, followed by American Indians or Alaskan Natives (3.8/100,000), and lowest among Asian or Pacific Islanders (0.9/100,000).
  • The risk of obesity-related cardiovascular disease death rose most rapidly among American Indians and Alaskan Natives.
  • Among Blacks, age-adjusted mortality was slightly higher among women than men (6.7/100,000 vs. 6.6/100,000), whereas the reverse was true for all other races (0.6-3.0/100,000 vs. 1.2-6.0/100,000).
  • Blacks living in urban settings experienced higher rates of age-adjusted cardiovascular mortality than those living in rural areas (6.8/100,000 vs. 5.9/100,000), whereas the opposite was true for all other racial groups (0.9-3.5/100,000 vs. 2.2-5.4/100,000).

IN PRACTICE:

“There is need for dedicated health strategies aimed at individual communities to better understand and tackle the social determinants of obesity and to design interventions that may alleviate the population burden of both obesity and cardiovascular disease,” the authors wrote.

SOURCE:

The study, by Zahra Raisi-Estabragh, MD, PhD, Queen Mary University, London, and colleagues, was published online Sept. 6 in the Journal of the American Heart Association.

LIMITATIONS:

  • Database limited to U.S. residents.
  • Possible miscoding or diagnostic errors.
  • Potential for residual confounding.
  • No data on underlying drivers of observed trends.

DISCLOSURES:

Dr. Raisi-Estabragh has reported receiving funding from the Integrated Academic Training program of the National Institute for Health Research and a Clinical Research Training Fellowship from the British Heart Foundation. Another author has reported receiving research support from the National Heart, Lung, and Blood Institute.

Can a decrease in dopamine lead to binge eating?

Article Type
Changed
Mon, 09/11/2023 - 18:05

In medical school, we were repeatedly advised that there is both a science and an art to the practice of medicine. In these days of doc-in-a-box online consultations for obesity, it’s tempting to think that there’s a one-size-fits-all purely scientific approach for these new weight loss medications. Yet, for every nine patients who lose weight seemingly effortlessly on this class of medication, there is always one whose body stubbornly refuses to submit.

Adam is a 58-year-old man who came to me recently because he was having difficulty losing weight. Over the past 20 years, he’d been steadily gaining weight and now, technically has morbid obesity (a term which should arguably be obsolete). His weight gain is complicated by high blood pressure, high cholesterol, and obstructive sleep apnea. His sleep apnea has caused such profound exhaustion that he no longer has the energy to work out. He also has significant ADHD, which has been left untreated because of his ability to white-knuckle it through his many daily meetings and calls. A married father of three, he is a successful portfolio manager at a high-yield bond fund.

Adam tends to eat minimally during the day, thereby baffling his colleagues with the stark contrast between his minimal caloric intake and his large belly. However, when he returns from work late at night (kids safely tucked into bed), the floodgates open. He reports polishing off pints of ice cream, scarfing down bags of cookies, inhaling trays of brownies. No carbohydrate is off limits to him once he steps off the Metro North train and crosses the threshold from work to home. 

Does Adam simply lack the desire or common-sense willpower to make the necessary changes in his lifestyle or is there something more complicated at play?

I would argue that Adam’s ADHD triggered a binge-eating disorder (BED) that festered unchecked over the past 20 years. Patients with BED typically eat massive quantities of food over short periods of time – often when they’re not even hungry. Adam admitted that he would generally continue to eat well after feeling stuffed to the brim. It is well known that ADHD is a leading cause of binge-eating tendencies. So, what is the link between these two seemingly unrelated disorders?

The answer probably lies with dopamine, a neurotransmitter produced in the reward centers of the brain that regulates how people experience pleasure and control impulses. We believe that people with ADHD have low levels of dopamine (it’s actually a bit more complicated, but this is the general idea). These low levels of dopamine lead people to self-medicate with sugars, salt, and fats to increase dopamine levels.

Lisdexamfetamine (Vyvanse) is a Food and Drug Administration–approved treatment option for both ADHD and binge eating. It raises the levels of dopamine (as well as norepinephrine) in the brain’s reward center. Often, the strong urge to binge subsides rapidly once ADHD is properly treated.

Rather than starting Adam on a semaglutide or similar agent, I opted to start him on lisdexamfetamine. When I spoke to him 1 week later, he confided that the world suddenly shifted into focus, and he was able to plan his meals throughout the day and resist the urge to binge late at night.

I may eventually add a semaglutide-like medication if his weight loss plateaus, but for now, I will focus on raising his dopamine levels to tackle the underlying cause of his weight gain.

Treating fractures in elderly patients: Beyond the broken bone

Article Type
Changed
Thu, 09/14/2023 - 07:24

While half the fracture-prevention battle is getting people diagnosed with low bone density, nearly 80% of older Americans who suffer bone breaks are not tested or treated for osteoporosis. Fractures associated with aging and diminished bone mineral density exact an enormous toll on patients’ lives and cost the health care system billions of dollars annually according to Bone Health and Osteoporosis: A Report of the Surgeon General. But current gaps in patient education and bone density screening are huge.

“It’s concerning that older patients at risk for fracture are often not screened to determine their risk factors contributing to osteoporosis and patients are not educated about fracture prevention,” said Meryl S. LeBoff, MD, an endocrinologist at Brigham and Women’s Hospital, and chief of calcium and bone section, and professor of medicine, at Harvard Medical School, Boston. “Furthermore, the majority of highest-risk women and men who do have fractures are not screened and they do not receive effective, [Food and Drug Administration]–approved therapies.”

Brigham and Women's Hospital
Dr. Meryl S. LeBoff

Recent guidelines

Screening with dual-energy x-ray absorptiometry (DEXA) is recommended for all women at age 65 and all men at age 70. But the occasion of a fracture in an older person who has not yet met these age thresholds should prompt a bone density assessment.

“Doctors need to stress that one in two women and one in four men over age 50 will have a fracture in their remaining lifetimes,” Dr. LeBoff said. ”Primary care doctors play a critical role in ordering timely bone densitometry for both sexes.

If an older patient has been treated for a fracture, the main goal going forward is to prevent another one, for which the risk is highest in the 2 years after the incident fracture.”

Johns Hopkins Medicine
Dr. Kendall F. Moseley

According to Kendall F. Moseley, MD, clinical director of the division of endocrinology, diabetes & metabolism at Johns Hopkins Medicine in Baltimore, “Elderly patients need to understand that a fracture at their age is like a heart attack of the bone,” she said, adding that just as cardiovascular risk factors such as high blood pressure and blood lipids are silent before a stroke or infarction, the bone thinning of old age is also silent.

Endocrinologist Jennifer J. Kelly, DO, director of the metabolic bone program and an associate professor at the University of Vermont Medical Center in Burlington, said a fracture in anyone over age 50 that appears not to have resulted from a traumatic blow, is a compelling reason to order a DEXA exam.

Nahid J. Rianon, MBBS/MD, DrPH, assistant professor of the division of geriatric medicine at the UTHealth McGovern Medical School, Houston, goes further: “Any fracture in someone age 50 and older warrants screening for osteoporosis. And if the fracture is nontraumatic, that is by definition a clinical diagnosis of osteoporosis regardless of normal results on bone density tests and they should be treated medically. There are aspects of bone that we still can’t measure in the clinical setting.”

UTHealth McGovern Medical School
Dr. Nahid J. Rianon


If DEXA is not accessible, fracture risk over the next 10 years can be evaluated based on multiple patient characteristics and medical history using the online FRAX calculator.

Just a 3% risk of hip fracture on FRAX is considered an indication to begin medical osteoporosis treatment in the United States regardless of bone density test results, Dr. Rianon said.
 

 

 

Fracture management

Whether a senior suffers a traumatic fracture or an osteoporosis-related fragility fracture, older age can impede the healing process in some. Senescence may also increase systemic proinflammatory status, according to Clark and colleagues, writing in Current Osteoporosis Reports.

They called for research to develop more directed treatment options for the elderly population.

Dr. Rianon noted that healing may also be affected by a decrease in muscle mass, which plays a role in holding the bone in place. “But it is still controversial how changing metabolic factors affect bone healing in the elderly.”

However, countered Dr. Kelly, fractures in elderly patients are not necessarily less likely to mend – if osteoporosis is not present. “Many heal very well – it really depends more upon their overall health and medical history. Whether or not a person requires surgery depends more upon the extent of the fracture and if the bone is able to align and heal appropriately without surgery.”

Fracture sites

Spine. According to the American Academy of Orthopedic Surgeons the earliest and most frequent site of fragility fractures in the elderly is the spine. Most vertebral fracture pain improves within 3 months without specific treatment. A short period of rest, limited analgesic use, and possible back bracing may help as the fractures heal on their own. But if pain is severe and persistent, vertebral augmentation with percutaneous kyphoplasty or vertebroplasty may be an option. These procedures, however, can destabilize surrounding discs because of the greater thickness of the injected cement.

Hip. The most dangerous fractures occur in the hip. These carry at least a 20% risk of death in the first postoperative year and must be treated surgically. Those in the proximal femur, the head, or the femoral neck will usually need hip replacement, but if the break is farther down, it may be repaired with cement, screws, plates, and rods.

Distal radius. Outcomes of wrist fractures may be positive without surgical intervention, according to a recent retrospective analysis from Turkey by Yalin and colleagues. In a comparison of clinical outcomes in seniors aged 70-89 and assigned to cast immobilization or various surgical treatments for distal radius fractures, no statistically significant difference was found in patient-reported disability scores and range of motion values between casting and surgery in the first postoperative year.

Other sites. Fractures in the elderly are not uncommon in the shoulder, distal radius, cubitus, proximal humerus, and humerus. These fractures are often treated without surgery, but nevertheless signal a high risk for additional fractures.

Bone-enhancing medications

Even in the absence of diagnosed low bone density or osteoporosis, anabolic agents such as the synthetic human parathyroid hormones abaloparatide (Tymlos) and teriparatide (Forteo) may be used to help in some cases with a bad healing prognosis and may also be used for people undergoing surgeries such as a spinal fusion, but there are not clinical guidelines. “We receive referrals regularly for this treatment from our orthopedics colleagues, but it is considered an off-label use,” Dr. Kelly said.

The anabolics teriparatide and romosozumab (Evenity) have proved effective in lowering fractures in high-risk older women.

Post fracture

After recovering from a fracture, elderly people are strongly advised to make lifestyle changes to boost bone health and reduce risk of further fractures, said Willy M. Valencia, MD, a geriatrician-endocrinologist at the Cleveland Clinic. Apart from active daily living, he recommends several types of formal exercise to promote bone formation; increase muscle mass, strength, and flexibility; and improve endurance, balance, and gait. The National Institute on Aging outlines suitable exercise programs for seniors.

“These exercises will help reduce the risk of falling and to avoid more fractures,” he said. “Whether a patient has been exercising before the fracture or not, they may feel some reticence or reluctance to take up exercise afterwards because they’re afraid of having another fracture, but they should understand that their fracture risk increases if they remain sedentary. They should start slowly but they can’t be sitting all day.”

Even before it’s possible to exercise at the healing fracture site, added Dr. Rianon, its advisable to work other areas of the body. “Overall mobility is important, and exercising other parts of the body can stimulate strength and help prevent falling.”

In other postsurgical measures, a bone-friendly diet rich in calcium and vitamin D, as well as supplementation with these vital nutrients, is essential to lower the risk of falling.

Fall prevention is paramount, said Dr. Valencia. While exercise can improve, gait, balance, and endurance, logistical measures may also be necessary. Seniors may have to move to a one-floor domicile with no stairs to negotiate. At the very least, they need to fall-proof their daily lives by upgrading their eyeglasses and home lighting, eliminating obstacles and loose carpets, fixing bannisters, and installing bathroom handrails. Some may need assistive devices for walking, especially outdoors in slippery conditions.

At the end of the day, the role of the primary physician in screening for bone problems before fracture and postsurgical care is key. “Risk factors for osteoporosis and fracture risk must be added to the patient’s chart,” said Dr. Rianon. Added Dr. Moseley. “No matter how busy they are, my hope is that primary care physicians will not put patients’ bone health at the bottom of the clinical agenda.”

While half the fracture-prevention battle is getting people diagnosed with low bone density, nearly 80% of older Americans who suffer bone breaks are not tested or treated for osteoporosis. Fractures associated with aging and diminished bone mineral density exact an enormous toll on patients’ lives and cost the health care system billions of dollars annually according to Bone Health and Osteoporosis: A Report of the Surgeon General. But current gaps in patient education and bone density screening are huge.

“It’s concerning that older patients at risk for fracture are often not screened to determine their risk factors contributing to osteoporosis and patients are not educated about fracture prevention,” said Meryl S. LeBoff, MD, an endocrinologist at Brigham and Women’s Hospital, and chief of calcium and bone section, and professor of medicine, at Harvard Medical School, Boston. “Furthermore, the majority of highest-risk women and men who do have fractures are not screened and they do not receive effective, [Food and Drug Administration]–approved therapies.”

Recent guidelines

Screening with dual-energy x-ray absorptiometry (DEXA) is recommended for all women at age 65 and all men at age 70. But the occasion of a fracture in an older person who has not yet met these age thresholds should prompt a bone density assessment.

“Doctors need to stress that one in two women and one in four men over age 50 will have a fracture in their remaining lifetimes,” Dr. LeBoff said. ”Primary care doctors play a critical role in ordering timely bone densitometry for both sexes.

If an older patient has been treated for a fracture, the main goal going forward is to prevent another one, for which the risk is highest in the 2 years after the incident fracture.”

According to Kendall F. Moseley, MD, clinical director of the division of endocrinology, diabetes & metabolism at Johns Hopkins Medicine in Baltimore, “Elderly patients need to understand that a fracture at their age is like a heart attack of the bone,” she said, adding that just as cardiovascular risk factors such as high blood pressure and blood lipids are silent before a stroke or infarction, the bone thinning of old age is also silent.

Endocrinologist Jennifer J. Kelly, DO, director of the metabolic bone program and an associate professor at the University of Vermont Medical Center in Burlington, said a fracture in anyone over age 50 that appears not to have resulted from a traumatic blow, is a compelling reason to order a DEXA exam.

Nahid J. Rianon, MBBS/MD, DrPH, assistant professor of the division of geriatric medicine at the UTHealth McGovern Medical School, Houston, goes further: “Any fracture in someone age 50 and older warrants screening for osteoporosis. And if the fracture is nontraumatic, that is by definition a clinical diagnosis of osteoporosis regardless of normal results on bone density tests and they should be treated medically. There are aspects of bone that we still can’t measure in the clinical setting.”

If DEXA is not accessible, fracture risk over the next 10 years can be evaluated based on multiple patient characteristics and medical history using the online FRAX calculator.

Just a 3% risk of hip fracture on FRAX is considered an indication to begin medical osteoporosis treatment in the United States regardless of bone density test results, Dr. Rianon said.
 

 

 

Fracture management

Whether a senior suffers a traumatic fracture or an osteoporosis-related fragility fracture, older age can impede the healing process in some. Senescence may also increase systemic proinflammatory status, according to Clark and colleagues, writing in Current Osteoporosis Reports.

They called for research to develop more directed treatment options for the elderly population.

Dr. Rianon noted that healing may also be affected by a decrease in muscle mass, which plays a role in holding the bone in place. “But it is still controversial how changing metabolic factors affect bone healing in the elderly.”

However, countered Dr. Kelly, fractures in elderly patients are not necessarily less likely to mend – if osteoporosis is not present. “Many heal very well – it really depends more upon their overall health and medical history. Whether or not a person requires surgery depends more upon the extent of the fracture and if the bone is able to align and heal appropriately without surgery.”

Fracture sites

Spine. According to the American Academy of Orthopedic Surgeons the earliest and most frequent site of fragility fractures in the elderly is the spine. Most vertebral fracture pain improves within 3 months without specific treatment. A short period of rest, limited analgesic use, and possible back bracing may help as the fractures heal on their own. But if pain is severe and persistent, vertebral augmentation with percutaneous kyphoplasty or vertebroplasty may be an option. These procedures, however, can destabilize surrounding discs because of the greater thickness of the injected cement.

Hip. The most dangerous fractures occur in the hip. These carry at least a 20% risk of death in the first postoperative year and must be treated surgically. Those in the proximal femur, the head, or the femoral neck will usually need hip replacement, but if the break is farther down, it may be repaired with cement, screws, plates, and rods.

Distal radius. Outcomes of wrist fractures may be positive without surgical intervention, according to a recent retrospective analysis from Turkey by Yalin and colleagues.

When does a bicarb drip make sense?

Article Type
Changed
Wed, 09/06/2023 - 20:51

 

A 70-year-old woman is admitted to the intensive care unit with a pH of 7.1, an acute kidney injury (AKI), and ketonuria. She is volume depleted and her history is consistent with starvation ketosis. This LOL truly is in NAD (that’s little old lady in no acute distress, for those who haven’t read The House of God). She is clinically stable and seemingly unperturbed by the flurry of activity surrounding her admission.

Your resident is concerned by the severity of the acidosis and suggests starting an intravenous bicarbonate drip. The fellow is adamantly against it. He’s been taught that intravenous bicarbonate increases the serum pH but paradoxically causes intracellular acidosis. As the attending you elect to observe fellow autonomy – no bicarb is given. Because any debate on rounds is a “teachable moment,” you decide to review the evidence and physiology behind infusing bicarbonate.
 

What do the data reveal?

An excellent review published in CHEST in 2000 covers the physiologic effects of bicarbonate, specifically related to lactic acidosis, which our patient didn’t have. Aside from that difference, the review validates the fellow’s opinion. In short, the authors stated that a low pH may be a marker of a dangerous systemic condition, but it need not be corrected for its own sake. It is unlikely to provoke hemodynamic or respiratory compromise outside the setting of shock or hypercapnia. Intravenous bicarbonate can lead to intracellular acidosis, hypercapnia, hypocalcemia, and a reduction in oxygen delivery via the Bohr effect. The authors concluded that because the benefits are unproven and the negative effects are real, intravenous bicarbonate should not be used to correct a metabolic acidosis.

The CHEST review hardly settles the issue, though. A survey published a few years later found a majority of intensivists and nephrologists used intravenous bicarbonate to treat metabolic acidosis while the Surviving Sepsis Campaign Guidelines for the Management of Sepsis and Septic Shock published in 2017 recommended against bicarbonate for acidosis. It wasn’t until 2018 that we reached the holy grail: a randomized controlled trial.

The BICAR-ICU study randomly assigned patients with a pH of 7.20 or less, PCO2 of 45 mm Hg or less, and sodium bicarbonate concentration of 20 mmol/L or less to receive no bicarbonate versus a sodium bicarbonate drip to maintain a pH greater than 7.30. There’s additional nuance to the trial design and even more detail in the results. To summarize, there was signal for an improvement in renal outcomes across all patients, and those with AKI saw a mortality benefit. Post–BICAR-ICU iterations of the Surviving Sepsis Campaign Guidelines have incorporated these findings by recommending intravenous bicarbonate for patients with sepsis who have AKI and a pH of 7.20 or less.

That’s not to say BICAR-ICU has settled the issue. Although it’s far and away the best we have, there were fewer than 400 total patients in their intention-to-treat analysis. It was open label, with lots of crossover. The primary outcome was negative for the entire population, with only a subgroup (albeit a prespecified one) showing benefit. Finally, the results weren’t stratified by etiology for the metabolic acidosis. There was also evidence of alkalosis and hypocalcemia in the treatment group.

Last but not least in terms of importance, in most cases when bicarbonate is being considered, wouldn’t some form of renal replacement therapy (RRT) be preferred? This point was raised by nephrologists and intensivists when we covered BICAR-ICU in a journal club at my former program. It’s also mentioned in an accompanying editorial. RRT timing is controversial, and a detailed discussion is outside the scope of this piece and beyond the limits of my current knowledge base. But I do know that the A in the A-E-I-O-U acute indications for dialysis pneumonic stands for acidosis.

Our patient had AKI, a pH of 7.20 or less, and a pCO2 well under 45 mm Hg. Does BICAR-ICU support the resident’s inclination to start a drip? Sort of. The majority of patients enrolled in BICAR-ICU were in shock or were recovering from cardiac arrest, so it’s not clear the results can be generalized to our LOL with starvation ketosis. Extrapolating from studies of diabetic ketoacidosis (DKA) seems more appropriate, and here the data are poor but equivocal. Reviews are generally negative but don’t rule out the use of intravenous bicarbonate in certain patients with DKA.
 

Key takeaways

Our patient survived a 24-hour ICU stay with neither cardiopulmonary decompensation nor a need for RRT. Not sure how she did out of the ICU; presumably she was discharged soon after transfer. As is always the case with anecdotal medicine, the absence of a control prevents assessment of the counterfactual. Is it possible she may have done “better” with intravenous bicarbonate? Seems unlikely to me, though I doubt there would have been demonstrable adverse effects. Perhaps next time the fellow can observe resident autonomy?

This point was raised by nephrologists and intensivists when we covered BICAR-ICU in a journal club at my former program. It’s also mentioned in an accompanying editorial. RRT timing is controversial, and a detailed discussion is outside the scope of this piece and beyond the limits of my current knowledge base. But I do know that the A in the A-E-I-O-U acute indications for dialysis pneumonic stands for acidosis.

Our patient had AKI, a pH of 7.20 or less, and a pCO2 well under 45 mm Hg. Does BICAR-ICU support the resident’s inclination to start a drip? Sort of. The majority of patients enrolled in BICAR-ICU were in shock or were recovering from cardiac arrest, so it’s not clear the results can be generalized to our LOL with starvation ketosis. Extrapolating from studies of diabetic ketoacidosis (DKA) seems more appropriate, and here the data are poor but equivocal. Reviews are generally negative but don’t rule out the use of intravenous bicarbonate in certain patients with DKA.
 

Key takeaways

Our patient survived a 24-hour ICU stay with neither cardiopulmonary decompensation nor a need for RRT. Not sure how she did out of the ICU; presumably she was discharged soon after transfer. As is always the case with anecdotal medicine, the absence of a control prevents assessment of the counterfactual. Is it possible she may have done “better” with intravenous bicarbonate? Seems unlikely to me, though I doubt there would have been demonstrable adverse effects. Perhaps next time the fellow can observe resident autonomy?

The surprising way to fight asthma symptoms

Article Type

Wed, 09/06/2023 - 14:11

 

Asthma is a sneaky foe.

“Asthma may appear controlled until someone exercises,” said Maureen George, PhD,  a professor of nursing at Columbia University and a spokesperson for the Asthma and Allergy Foundation of America. 

But that doesn’t mean exercise should be avoided, she said. 

Exercise, in fact, is one of the best ways to reduce asthma symptoms. Research over the past 2 decades has shown that physical activity can help improve lung function and boost quality of life for someone with asthma. 

As their fitness improves, asthma patients report better sleep, reduced stress, improved weight control, and more days without symptoms. In some cases, they’re able to cut down their medication doses.  

Exercise reduces inflammatory cytokines and increases anti-inflammatory cytokines, according to a 2023 review by researchers in the United Kingdom. That could help calm chronic airway inflammation, easing symptoms of asthma. 

A few simple guidelines can help patients reap those benefits while staying safe.


 

Make sure the first steps aren’t the last steps

For someone who’s new to exercise, there’s only one way to begin: Carefully.

The Global Initiative for Asthma recommends twice-weekly cardio and strength training.

“You always start low and slow,” said Spencer Nadolsky, DO, a board-certified obesity and lipid specialist and medical director of Sequence, a comprehensive weight management program.

“Low” means light loads in the weight room. “Slow” means short, easy walks. 

Many have been put “through the wringer” when starting out, discouraging them from continuing, Dr. Nadolsky said. “They were too sore, and it felt more like punishment.”

An even bigger concern is triggering an asthma attack. Patients should take steps to lower the risk by carrying their rescue inhalers and keeping up on medications, he added.

“A health care professional should be consulted” before the start of a new activity or ramping up a program, or anytime asthma interferes with a workout, Dr. George said. 

Those who exercise outside need to be aware of the air quality, especially at a time when smoke and particulates from a wildfires in Canada can trigger asthma symptoms in people thousands of miles away. 

The harder one works, the higher one’s “ventilation” – taking more air into the lungs, and potentially more allergens and pollutants.

Temperature and humidity also become risky at the extremes. Cold, dry air can dehydrate and constrict the airways, making it hard to breathe. 
 

How to choose the best type of exercise 

Step 1: Be realistic. People with asthma often have less exercise capacity than those who don’t – understandable when shortness of breath is the default setting.

Second, allow for plenty of time to warm up. A solid warm-up routine – particularly one with a mix of lower- and higher-intensity exercises – may help prevent exercise-induced bronchoconstriction causing shortness of breath and wheezing.

For example, warming up on a treadmill or exercise bike could be mixed with a few short bursts of faster running or cycling, with a couple of minutes of recovery at a slower pace in between.

That concept can be expanded into a full-blown workout. 

High-intensity interval training (HIIT) is a promising option for people with asthma. A 2021 study showed that three 20-minute interval workouts per week significantly improved asthma control.

“The benefit of HIIT is that ventilation is able to recover intermittently,” said Carley O’Neill, PhD, an exercise scientist at Acadia University in Nova Scotia and the study’s lead author. 

That’s a key difference from conventional cardio, where the constant exertion can evaporate water from the lungs faster than your body can replenish it. “Dehydrating of the airways can, in some, trigger exercise-induced asthma,” Dr. O’Neill said. 

HIIT, conversely, allows the airways to recover and rehydrate between exercise bouts. 

Another recent study found that people with asthma who did HIIT workouts had fewer breathing problems and felt less fatigued, compared with a matched group who did cardio training at a constant pace. (Both types of cardio led to similar improvements in aerobic fitness.)

Individuals can choose other types of intermittent exercise as well. Strength training, for example, requires relatively short periods of exertion, with plenty of rest in between. 
 

 

 

The one choice you don’t want to make

While there are lots of good exercise options for someone with asthma, there’s one clearly bad choice, according to Dr. George: “Avoiding exercise.”  

Being inactive puts one at higher risk for obesity and all the health problems that go with it. And allowing one’s fitness level to decline makes it much harder to move when one needs or wants to.

Any choice is better than that one.

Psilocybin reduces symptoms, disability in major depression

Article Type
Changed
Thu, 09/07/2023 - 10:29

A single dose of an experimental psilocybin drug offered significant sustained improvement in symptoms and disability in patients with major depressive disorder (MDD) over a 6-week period, results of a study suggest.

The randomized, phase 2 trial was conducted at 11 sites across the United States and is the latest to demonstrate the psychedelic drug’s potential as a treatment for depression.

The project was funded by Usona Institute, a nonprofit medical research organization based in Madison, Wisc. The institute issued a press statement, but researchers did not comment further on the findings.

“As the largest and most rigorous study conducted across a wide spectrum of individuals with major depressive disorder, the results show promise for all people struggling with this condition,” lead author Charles Raison, MD, director of clinical and translational research at Usona, said in the statement. 

The 34 coauthors on the study are affiliated with public universities, research centers, and private companies. Eight of the investigators are identified as employees of Usona Institute.

Declining further comment, an institute spokesperson told this news organization that, “Usona has chosen the approach of no interviews, and this applies for all coauthors.”

The findings were published online in JAMA.
 

Largest study to date

Usona’s investigational psilocybin drug has been granted a breakthrough designation by the Food and Drug Administration, a process designed to speed drug development and review.

Previous smaller studies have suggested a rapid antidepressant response with psilocybin, but they have been small, unblinded, and have had short duration of follow-up, they write. This randomized, double-blind, phase 2 clinical trial is the largest study of psilocybin for depression to date, the researchers note.

It included 104 adults aged 21-65 years with MDD who had a current depressive episode of at least 60 days and a Montgomery-Åsberg Depression Rating Scale (MADRS) total score of 28 or more at baseline.

Participants had to be free of psychedelic drugs for at least 5 years, have had no active suicidal ideation or suicidal behavior in the prior 12 months, no personal or first-degree family history of psychosis or mania, and no history of moderate/severe alcohol or drug use disorder.

Before the study, participants had a 7- to 35-day screening period for psychiatric medication tapering, underwent baseline assessments, and received 6-8 hours of preparation with two facilitators who would be with them during dosing.

Dosing occurred within 7 days of baseline assessments. During the 6- to 8-hour session, participants received either a single 25-mg oral dose of psilocybin or 100-mg dose of niacin. One participant randomly assigned to receive psilocybin received the incorrect treatment, resulting in 50 participants receiving psilocybin and 54 receiving niacin.

Participants returned the next day, the next week, and then every 2 weeks for assessments, for a follow-up of 6 weeks.
 

Psychosocial support

Participants who received psilocybin reported significantly greater improvements in MDD symptoms, compared with those who received niacin. MADRS scores – a scale from 0 to 60 where higher scores indicate more severe depression – showed greater reductions with treatment vs. placebo at 8 days (mean difference, −12.0; 95% confidence interval, −16.6 to −7.4; P < .001), and at day 43 (mean difference, −12.3; 95% CI, −17.5 to −7.2; P < .001).

More participants receiving psilocybin had sustained depressive symptom response (42% vs. 11%; P = .002) and more improvement in the Sheehan Disability Scale score, which measures functional disability, 43 days after treatment (P < .001).

The effects persisted through the end of the study, although the differences between groups were no longer significant by week 6.

Dr. Greg Fonzo

“This is another exciting piece of evidence that adds to the current literature regarding the potential efficacy of psilocybin for the treatment of mental health conditions, particularly depression,” said Greg Fonzo, MD, codirector of the Center for Psychedelic Research and Therapy at the University of Texas at Austin, who commented on the findings.

Significantly more people in the psilocybin group reported at least one treatment-related adverse event (AE, 82% vs. 44%), although most were mild to moderate. Headache and nausea were the most common side effects and most resolved within 1 day of dosing.

While those numbers are high, Dr. Fonzo said they’re not out of line with AEs reported in other studies.

“Particularly with the types of adverse events reported here, like headache and nausea, those are things you would typically expect to see in this treatment,” said Dr. Fonzo, who was not part of the research.

“But it is high, and it underscores that this is not a treatment without certain risks, even though it was good that they were primarily mild in severity,” he added.
 

A ‘stepping stone’ to FDA approval?

The use of tools to measure disability in addition to symptoms of depression severity is a strength of the study, Dr. Fonzo added. The use of an active comparator and the 6-week follow-up also offer something new over previous studies.

Despite the longer follow up, questions remain about the durability of response, something only a longer study could answer, Dr. Fonzo said. The small and homogeneous sample-size are also a concern. Nearly 90% of participants were White, and more than half had an income of $75,000 a year or higher.

“It’s another stepping stone in the process to FDA approval, but the next step in that process would be much larger phase 3 trials that would have much larger samples, a longer follow-up, and hopefully have a more inclusive swath of the population,” Dr. Fonzo said.

But perhaps one of the most significant limitations is the use of niacin as an active comparator, said Caleb Alexander, MD, codirector of the Center for Drug Safety and Effectiveness at Johns Hopkins University in Baltimore.

Dr. Caleb Alexander

The use of an agent that doesn’t produce effects similar to those expected from a psychedelic introduced the potential for functional unblinding, Dr. Alexander said. Investigators did not ask participants to guess whether they received psilocybin or niacin, so the quality of the blinding was not assessed in the study.

“We’d like to see the use of [an] active comparator that might have a chance of obscuring to people as to whether they’ve been randomized to the treatment arm or control arm,” said Dr. Alexander, who wasn’t involved in the study. “Why not use a benzodiazepine or another drug that produces a transient euphoria that would better obscure whether or not people were receiving the psilocybin?”

The authors of an accompanying editorial shared these concerns, also noting that the study included “a significant number of patients who did not respond to therapy.”

“It is important to analyze and understand adverse outcomes in psychedelic trials and conduct longitudinal studies to determine how sustained the effects will be and what may initiate a recrudescence of symptoms,” write Rachel Yehuda, PhD, and Amy Lehrner, PhD, both of the Peters VA Medical Center and Icahn School of Medicine at Mount Sinai, New York.

Dr. Rachel Yehuda

“Future studies will help identify who is most likely to benefit from psychedelics, whether booster or repeated treatment is safe and beneficial, and what the optimal dose and therapeutic frameworks are.”

A long-term follow-up of the current trial was terminated last year because of low enrollment. The spokesperson with Usona Institute did not respond to questions about that study, and the institute’s statement only added that preparations are underway to launch another study that “will provide additional safety and efficacy data to support submission of a new drug application to the FDA.”

Usona published its manufacturing process that it used to synthesize psilocybin in an open-access journal and signed a statement on “open science and open praxis” with psilocybin and similar substances, which appears on their website. That statement was signed by 31 research and service organizations around the world and nearly 150 scientists, scholars, and practitioners.

The study was funded by Usona Institute. Dr. Raison reported receiving personal fees from Usona Institute and grants to Usona Institute from Dr. Bronner’s All-One, Fournier Family Foundation, Good Ventures, Steven and Alexandra Cohen Foundation, Tiny Blue Dot Foundation, Turnbull Family Foundation, and William A. Linton during the conduct of the study; and personal fees from Novartis, Sage/Biogen, Emory Healthcare, and Vail Health outside the submitted work. Dr. Fonzo and Dr. Alexander report no relevant financial relationships. Dr. Yehuda reports receiving nonfinancial support from the Multidisciplinary Association for Psychedelic Studies Public Benefit (MAPS PBC) and grants from COMPASS Pathways. Dr. Lehrner is an investigator on trials sponsored by MAPS PBC and COMPASS Pathways.

A single dose of an experimental psilocybin drug offered significant sustained improvement in symptoms and disability in patients with major depressive disorder (MDD) over a 6-week period, results of a study suggest.

The randomized, phase 2 trial was conducted at 11 sites across the United States and is the latest to demonstrate the psychedelic drug’s potential as a treatment for depression.

The project was funded by Usona Institute, a nonprofit medical research organization based in Madison, Wisc. The institute issued a press statement, but researchers did not comment further on the findings.

“As the largest and most rigorous study conducted across a wide spectrum of individuals with major depressive disorder, the results show promise for all people struggling with this condition,” lead author Charles Raison, MD, director of clinical and translational research at Usona, said in the statement. 

The 34 coauthors on the study are affiliated with public universities, research centers, and private companies. Eight of the investigators are identified as employees of Usona Institute.

Declining further comment, an institute spokesperson told this news organization that, “Usona has chosen the approach of no interviews, and this applies for all coauthors.”

The findings were published online in JAMA.
 

Largest study to date

Usona’s investigational psilocybin drug has been granted a breakthrough designation by the Food and Drug Administration, a process designed to speed drug development and review.

Previous smaller studies have suggested a rapid antidepressant response with psilocybin, but they have been small, unblinded, and have had short duration of follow-up, they write. This randomized, double-blind, phase 2 clinical trial is the largest study of psilocybin for depression to date, the researchers note.

It included 104 adults aged 21-65 years with MDD who had a current depressive episode of at least 60 days and a Montgomery-Åsberg Depression Rating Scale (MADRS) total score of 28 or more at baseline.

Participants had to be free of psychedelic drugs for at least 5 years, have had no active suicidal ideation or suicidal behavior in the prior 12 months, no personal or first-degree family history of psychosis or mania, and no history of moderate/severe alcohol or drug use disorder.

Before the study, participants had a 7- to 35-day screening period for psychiatric medication tapering, underwent baseline assessments, and received 6-8 hours of preparation with two facilitators who would be with them during dosing.

Dosing occurred within 7 days of baseline assessments. During the 6- to 8-hour session, participants received either a single 25-mg oral dose of psilocybin or 100-mg dose of niacin. One participant randomly assigned to receive psilocybin received the incorrect treatment, resulting in 50 participants receiving psilocybin and 54 receiving niacin.

Participants returned the next day, the next week, and then every 2 weeks for assessments, for a follow-up of 6 weeks.
 

Psychosocial support

Participants who received psilocybin reported significantly greater improvements in MDD symptoms, compared with those who received niacin. MADRS scores – a scale from 0 to 60 where higher scores indicate more severe depression – showed greater reductions with treatment vs. placebo at 8 days (mean difference, −12.0; 95% confidence interval, −16.6 to −7.4; P < .001), and at day 43 (mean difference, −12.3; 95% CI, −17.5 to −7.2; P < .001).

More participants receiving psilocybin had sustained depressive symptom response (42% vs. 11%; P = .002) and more improvement in the Sheehan Disability Scale score, which measures functional disability, 43 days after treatment (P < .001).

The effects persisted through the end of the study, although the differences between groups were no longer significant by week 6.

“This is another exciting piece of evidence that adds to the current literature regarding the potential efficacy of psilocybin for the treatment of mental health conditions, particularly depression,” said Greg Fonzo, MD, codirector of the Center for Psychedelic Research and Therapy at the University of Texas at Austin, who commented on the findings.

Significantly more people in the psilocybin group reported at least one treatment-related adverse event (AE, 82% vs. 44%), although most were mild to moderate. Headache and nausea were the most common side effects and most resolved within 1 day of dosing.

While those numbers are high, Dr. Fonzo said they’re not out of line with AEs reported in other studies.

“Particularly with the types of adverse events reported here, like headache and nausea, those are things you would typically expect to see in this treatment,” said Dr. Fonzo, who was not part of the research.

“But it is high, and it underscores that this is not a treatment without certain risks, even though it was good that they were primarily mild in severity,” he added.
 

A ‘stepping stone’ to FDA approval?

The use of tools to measure disability in addition to symptoms of depression severity is a strength of the study, Dr. Fonzo added. The use of an active comparator and the 6-week follow-up also offer something new over previous studies.

Despite the longer follow up, questions remain about the durability of response, something only a longer study could answer, Dr. Fonzo said. The small and homogeneous sample-size are also a concern. Nearly 90% of participants were White, and more than half had an income of $75,000 a year or higher.

“It’s another stepping stone in the process to FDA approval, but the next step in that process would be much larger phase 3 trials that would have much larger samples, a longer follow-up, and hopefully have a more inclusive swath of the population,” Dr. Fonzo said.

But perhaps one of the most significant limitations is the use of niacin as an active comparator, said Caleb Alexander, MD, codirector of the Center for Drug Safety and Effectiveness at Johns Hopkins University in Baltimore.

The use of an agent that doesn’t produce effects similar to those expected from a psychedelic introduced the potential for functional unblinding, Dr. Alexander said. Investigators did not ask participants to guess whether they received psilocybin or niacin, so the quality of the blinding was not assessed in the study.

“We’d like to see the use of [an] active comparator that might have a chance of obscuring to people as to whether they’ve been randomized to the treatment arm or control arm,” said Dr. Alexander, who wasn’t involved in the study. “Why not use a benzodiazepine or another drug that produces a transient euphoria that would better obscure whether or not people were receiving the psilocybin?”

The authors of an accompanying editorial shared these concerns, also noting that the study included “a significant number of patients who did not respond to therapy.”

“It is important to analyze and understand adverse outcomes in psychedelic trials and conduct longitudinal studies to determine how sustained the effects will be and what may initiate a recrudescence of symptoms,” write Rachel Yehuda, PhD, and Amy Lehrner, PhD, both of the Peters VA Medical Center and Icahn School of Medicine at Mount Sinai, New York.

“Future studies will help identify who is most likely to benefit from psychedelics, whether booster or repeated treatment is safe and beneficial, and what the optimal dose and therapeutic frameworks are.”

A long-term follow-up of the current trial was terminated last year because of low enrollment. The spokesperson with Usona Institute did not respond to questions about that study, and the institute’s statement only added that preparations are underway to launch another study that “will provide additional safety and efficacy data to support submission of a new drug application to the FDA.”

Usona published its manufacturing process that it used to synthesize psilocybin in an open-access journal and signed a statement on “open science and open praxis” with psilocybin and similar substances, which appears on their website. That statement was signed by 31 research and service organizations around the world and nearly 150 scientists, scholars, and practitioners.

The study was funded by Usona Institute. Dr. Raison reported receiving personal fees from Usona Institute and grants to Usona Institute from Dr. Bronner’s All-One, Fournier Family Foundation, Good Ventures, Steven and Alexandra Cohen Foundation, Tiny Blue Dot Foundation, Turnbull Family Foundation, and William A. Linton during the conduct of the study; and personal fees from Novartis, Sage/Biogen, Emory Healthcare, and Vail Health outside the submitted work. Dr. Fonzo and Dr. Alexander report no relevant financial relationships. Dr. Yehuda reports receiving nonfinancial support from the Multidisciplinary Association for Psychedelic Studies Public Benefit (MAPS PBC) and grants from COMPASS Pathways. Dr. Lehrner is an investigator on trials sponsored by MAPS PBC and COMPASS Pathways.
