Use of antidotes in pregnancy and lactation
The human pregnancy data reported for these 16 agents are very limited as only 8 of the drugs have this data. However, the 8 reports indicated that the use of these drugs was highly important for the mother and did not cause embryo/fetal harm.
- Acetylcysteine
The need for this antidote in a pregnant or lactating woman is most likely a rare requirement. However, the need for this agent does occur in women who have taken a potentially hepatic toxic dose of acetaminophen (e.g., Tylenol).
- Black widow spider antivenin
Only three reports of the use of this agent in a pregnant woman have been located. In each case, the symptoms from the spider bite did not respond to other therapies but did within 1 hour to the antivenin. There was no fetal harm in these cases.
- Deferasirox
This agent is an oral iron-chelating agent used for the treatment of chronic iron overload. Five case reports have described its use without causing any fetal harm.
- Deferoxamine
This agent has been used in more than 65 pregnancies for acute iron overdose or for transfusion-dependent thalassemia. No reports have observed adverse human developmental effects.
- Digoxin immune FAB (ovine)
Several reports have described the use of this agent in pregnancy. No fetal harm has been observed, but none of the reports involved exposure during organogenesis. However, in cases of digoxin overdose, the maternal benefits of therapy should take priority over the embryo/fetus.
- Dimercaprol
Although the limited animal data suggest low risk, there are no reports of the use of this drug in human organogenesis. The absence of data prevents an assessment of the embryo-fetal risk, but the maternal benefit and indirect embryo-fetal benefit appears to outweigh that risk.
- Edetate calcium disodium
This agent is used to treat acute or chronic lead poisoning. It is compatible in pregnancy because the maternal and possibly the embryo-fetal benefit appears to outweigh any unknown direct or indirect risks.
- Flumazenil
The use of this drug in the third trimester has been reported in two cases. Because the drug is indicated to reverse the effects of benzodiazepines on the central nervous system, the maternal benefit should far outweigh the unknown embryo-fetal risk.
- Glucagon
The embryo-fetal risks appear to be very low. Apparently, the drug does not cross the placenta.
- Glucarpidase
This drug is indicated for the treatment of methotrexate toxicity. There are no reports describing the use of this drug in pregnancy or during breastfeeding.
- Idarucizumab
This agent is a humanized monoclonal antibody fragment that is indicated for the reversal of the anticoagulant effects of dabigatran. No reports describing its use in human or animal pregnancy have been located. However, the maternal benefit appears to be high and probably outweighs the unknown risk to the embryo/fetus.
- Lanthanum carbonate
There are no human pregnancy or lactation data. It is used to reduce blood levels of phosphate in people with kidney disease.
- Pralidoxime
This agent relieves the paralysis of the muscles of respiration caused by an organophosphate pesticide or related compound. The human pregnancy experience is limited to two cases, one at 36 weeks and the other at 16 weeks, both of which delivered normal infants.
- Sapropterin
Four reports have described the use of sapropterin to lower blood phenylalanine levels in 31 pregnancies. There were no embryo-fetal adverse effects attributable to the drug.
- Sevelamer
Sevelamer is used to control high blood levels of phosphorus in people with chronic kidney disease who are on dialysis. There are no human pregnancy or breastfeeding data.
- Succimer
This drug is a heavy metal–chelating agent that is indicated for the treatment of lead poisoning in pediatric patients. The drug was teratogenic in rats and mice. Two reports described the use of the drug in two pregnant women for lead poisoning. It has also been used as an antidote for the treatment of arsenic, mercury, and cadmium poisoning in adults, but there have been no reports of this use in pregnant patients.

How much weight does my patient need to lose?
What is the real goal of weight loss? In health care, reducing excess body fat is known to improve many complications faced by patients with obesity. Even modest to moderate weight loss contributes to improvements in health. Normalizing body weight is not required.
While our culture promotes an ideal body size, in the health care setting, our attention must focus on achieving health improvement. We need to be more tolerant of variations in body size if patients are healthy. Of note, varying amounts of weight loss produce improvement in the different complications of obesity, so the amount of weight loss required for improving one condition differs from that required to improve another condition.
When we prescribe weight loss for health improvement, we are trying to reduce both the mechanical burden of fat and the excess ectopic and visceral body fat that is driving disease. The good news about the physiology of weight loss is that we do not need to attain a body mass index (BMI) of 25 or even 30 to have health improvement. The excess abnormal body fat is the first to go!
Losing weight causes a disproportional reduction in ectopic and visceral fat depots. With a 5% weight loss, visceral fat is reduced by 9%. With 16% weight loss, visceral fat is reduced by 30%. Clearing of liver fat is even more dramatic. With 16% weight loss, 65% of liver fat is cleared.
Because ectopic abnormal fat is cleared preferentially with weight loss, it affects different tissues with varying amounts of weight loss.
Weight loss and diabetes
A close relationship exists between weight loss and insulin sensitivity. With just 5% weight loss, insulin sensitivity in the liver and adipose tissue is greatly improved, but while muscle insulin sensitivity is improved at just 5% weight loss, it continues to improve with further weight loss. Indeed, weight loss has enormous benefits in improving glycemia in prediabetes and diabetes.
In patients with impaired glucose tolerance, weight loss of 10% can eliminate progression to type 2 diabetes. In patients with type 2 diabetes who still have beta-cell reserve, 15% weight loss can produce diabetes remission – normoglycemia without diabetes medications.
Weight loss and cardiovascular risk factors
Even very small amounts of weight loss – 3% – can improve triglycerides and glycemia. It takes 5% weight loss to show benefits in systolic and diastolic blood pressure, as well as in HDL and LDL cholesterol levels. For all of these, additional weight loss brings more improvement. Inflammatory markers are more difficult. It takes 10%-15% weight loss to improve most of these – for example, C-reactive protein.
Weight loss and other complications
It takes 10% or more weight loss to demonstrate improvements in symptoms in obstructive sleep apnea and gastroesophageal reflux disease. For knee pain, the relationship to improvement is not based on achieving a percentage loss. Each pound of weight lost can result in a fourfold reduction in the load exerted on the knee per step during daily activities, but it is important to reduce weight before there is structural damage, because weight loss can’t repair damaged knee joints. Moderate weight loss (5%-10%) produces improvements in quality-of-life measures, in urinary stress incontinence symptoms, and in measures of sexual function. It probably takes 15% or more weight loss to demonstrate improvement in cardiovascular events.
Must heavier patients lose more weight?
To answer this question, it is important to think in terms of percent weight loss rather than pounds or kilograms. In large studies of lifestyle intervention, of course individuals with higher BMI lost more weight. But the percentage weight loss was the same across BMI categories: class 1 (BMI 30-35), class 2 (BMI 35-40), class 3 (BMI > 40). Furthermore, the improvement in risk factors was the same across BMI categories. Those with class 3 obesity had the same improvements as those with class 1. This provides further rationale for thinking about weight loss as a percentage from baseline weight rather than as simply a weight-loss goal in pounds.
Goal setting is an important part of any behavioral intervention
At the start of a weight-loss intervention, the health care provider should raise the issue of the goal and the time course for achieving it. Patients often have unrealistic expectations, wanting to achieve large amounts of weight loss rapidly. Unfortunately, popular culture has reinforced this idea with advertisements using “lose 10 pounds the first week” and promoting before-and-after pictures of weight-loss results. The job of the health care provider is to coach and guide the patient in terms of achievable weight loss that can bring health improvement safely. Managing patient expectations is critical to long-term success.
Think in terms of percentage weight loss, not pounds, and set goals at achievable time points
Help patients translate a percent weight-loss goal to a pounds goal at 3, 6, and 12 months. With the emergence of medications approved for chronic weight management with robust weight-loss efficacy, it now is possible to achieve a weight-loss goal of 10% or 15% with regularity, and some patients will be able to achieve 20% or 25% weight loss with newer medications.
We should help our patients set a goal by calculating a goal for certain time points. A good goal for 3 months would be 5% weight loss. For our 200-lb patient, we would translate that to 10 lb in 3 months. For 6 months, the goal should be 10% (20 lb for our 200-lb patient). The usual trajectory of weight loss with lifestyle intervention alone is for a “plateau” at 6 months, although with newer medications, weight loss will continue for more than a year. That 1-year goal might be 15% (30 lb for our 200-lb patient) or even more, based on the patient’s baseline weight and body composition.
Weight-loss calculators can be useful tools for patients and health care providers. They can be found online and include the National Institutes of Health Body Weight Planner and the Pennington Biomedical Weight Loss Predictor Calculator. These tools give patients a realistic expectation of how fast weight loss can occur and provide guidelines to measure success.
Can patients lose too much weight?
In this patient population, losing too much weight is not typically a concern. However, newer medications are achieving average weight losses of 17% and 22% at 62 weeks, as reported by this news organization. There is a wide variation in response to these newer agents which target appetite, and many patients are losing more than the average percentages.
Remembering that the goal of weight loss is the reduction of excess abnormal body fat, we want patients to preserve as much lean mass as possible. Weight-bearing exercise can help during the weight-loss phase, but large or rapid weight loss can be concerning, especially in older individuals. When the BMI drops below 25, we want to watch patients carefully. Measurement of body composition, including bone mineral density, with dual-energy x-ray absorptiometry (DEXA) can help. This is a scenario where dose reduction of antiobesity medication can be indicated, and good clinical judgment is required to keep weight loss at healthy levels.
The future of weight loss
In the past, our strategy has been to promote as much weight loss as possible. With more effective medications, our strategy will have to change to a treat-to-target approach, such as we already use in hypertension and diabetes.
With the ability to produce powerful effects on appetite will come the need to not only target weight loss but to target preservation of lean mass and even to target different approaches for weight-loss maintenance. At present, we have no evidence that stopping medications results in anything other than weight regain. The study of different approaches to weight-loss maintenance will require our full attention.

They can be found online and include the National Institutes of Health Body Weight Planner and the Pennington Biomedical Weight Loss Predictor Calculator. These tools give patients a realistic expectation of how fast weight loss can occur and provide guidelines to measure success.
Can patients lose too much weight?
In this patient population, losing too much weight is not typically a concern. However, newer medications are achieving average weight losses of 17% and 22% at 62 weeks, as reported by this news organization. There is a wide variation in response to these newer agents which target appetite, and many patients are losing more than the average percentages.
Remembering that the goal of weight loss is the reduction of excess abnormal body fat, we want patients to preserve as much lean mass as possible. Weight-bearing exercise can help during the weight-loss phase, but large or rapid weight loss can be concerning, especially in older individuals. When the BMI drops below 25, we want to watch patients carefully. Measurement of body composition, including bone mineral density, with dual-energy x-ray absorptiometry (DEXA) can help. This is a scenario where dose reduction of antiobesity medication can be indicated, and good clinical judgment is required to keep weight loss at healthy levels.
The future of weight loss
In the past, our strategy has been to promote as much weight loss as possible. With more effective medications, our strategy will have to change to a treat-to-target approach, such as we already use in hypertension and diabetes.
With the ability to produce powerful effects on appetite will come the need to not only target weight loss but to target preservation of lean mass and even to target different approaches for weight-loss maintenance. At present, we have no evidence that stopping medications results in anything other than weight regain. The study of different approaches to weight-loss maintenance will require our full attention.

In Memoriam: John Hickner, MD, MSc
We are deeply saddened by the recent death of our friend and colleague, John Hickner. Although we are grieving, we consider ourselves fortunate to have had John in our lives and to be able to share a few of his many accomplishments and attributes. Anyone who knew John knew that he had many gifts. But above all, John was kind, generous, and thoughtful. Val, John’s wife of 48 years, and their family were at the center of John’s world. Everything John did was a reflection of his love for his family.
John was a small-town family physician, and this guided virtually all of his professional endeavors. He was a member of the faculty for the Michigan State University Department of Family Medicine in Escanaba, in Michigan’s Upper Peninsula. While in the Upper Peninsula, he helped establish 2 practice-based research networks: the statewide Michigan Research Network (MiRNet) and the regional Upper Peninsula Research Network (UPRNet). If you ever had the chance to attend the UPRNet meetings, you would have observed the entire practice staff included in planning research activities, sharing, and troubleshooting common practice hiccups. At the end of those meetings, John would conclude by reading a children’s story such as Goodnight Moon or play a song on his guitar and then give a final thoughtful message.
In 1999, John worked with the American Academy of Family Physicians to create the National Research Network, now composed of more than 870 practices and nearly 2400 members. His own interests in respiratory infections, stemming from his experiences with his own children, led to work with the North American Respiratory Infection Study Group and with the Centers for Disease Control and Prevention.
John’s interests in practice-based research paralleled his interests in evidence-based medicine, largely as a way to translate research into daily practice. This focus on evidence guided much of his work as Editor-in-Chief for The Journal of Family Practice, a title he held for a decade. He also worked with state Academies of Family Physicians for more than a decade to create a new conference series centered on short, practical clinical topics and based completely on summaries of recent research. Any listener of the Primary Care Update podcasts could hear his thoughtful questioning of current research and his wise approach to its integration into practice.
John was more than a thoughtful and kind clinician, an outstanding educator, and a gifted researcher; he was a natural leader. John had the capacity to understand the systems in which he worked and was able to skillfully guide teams to improve those systems. He served as the Chair of Family Medicine at the Cleveland Clinic and then at the University of Illinois Chicago (UIC), and mentored many faculty, residents, and students during his time at those institutions.
After retiring from UIC, John and Val moved back to Escanaba. At his retirement dinner, his children (Michael, Laura, Zach, Anna, and Olivia) gifted him a beautiful maple acoustic guitar with which he then serenaded the attendees. John was an avid tennis player and often would tell us he would have to skip meeting us for dinner while away at a conference because he had found a tennis opponent! Most of all, he loved to set out on his 35-foot sailboat on Big Bay de Noc or on Green Bay. We have fond memories of the days spent sailing with John and hope that he has found fair winds and following seas.

‘I missed it’: Coping with medical error
Thursday night
It was 9 o’clock at night when my phone rang. I didn’t recognize the number but decided to answer it anyway. It was my doctor.
“Chase, I got your labs back and you have a critically low level. I spoke with someone at the hospital, I think I know what is happening, but I need you to go to the pharmacy right now and get a medicine.” She explained further and as I listened electric currents ran through my thighs until I could barely feel my legs.
“I’m so sorry, Chase. I missed it. It was low the last time we did your labs 9 months ago, and I missed it.”
In disbelief, I continued to listen as she instructed me about the next steps I was to take and prepared me for what was to come the next day.
“If you notice any changes overnight, go straight to the ED.”
My chest tingled and I could barely breathe. My mind struggled to comprehend what was happening. I looked at my husband sitting close by on the couch. He looked concerned. I tuned back in and heard her say: “Is your husband there? Can I talk to him?”
“Yes,” is all I could manage, and I handed him the phone. I sat while he listened and asked his questions. My breathing came back under my control, my legs felt wiry, and restlessness set in. “I have to get out of here,” I thought. “I have to go and pick up this medicine.”
Monday afternoon
I am sitting across from a PGY3 resident I have been treating since his intern year, as part of his treatment plan for managing a chronic mental illness that began in medical school. Earlier in the day, I received an urgent message from him requesting an emergency appointment.
Within a few minutes of sitting down, the story from his weekend call shift tumbled out of him. His speech became pressured, and his eyes welled with tears as he recounted in detail the steps he had taken to care for a very sick patient overnight.
“I missed it.” The dam broke and he sat sobbing in front of me, his body trembling.
I sat silently across from him. Willing him to breathe.
In time, his breathing came back under his control, and he slowly regained his composure. He continued: “I got the imaging, and I missed a bleed.”
Failure and shame
I can recall memorable moments from my training when I came to understand that what I initially perceived to be a mistake was instead part of the work. An example from our practice involves a patient whom I was comanaging with her primary care provider (PCP). She was not doing well following a critical work event. When I met with her after the event, she admitted having thoughts of suicide, refused a voluntary inpatient admission, and would not have met criteria for an involuntary admission. My hands were tied.
Together we created a plan to keep her safe, which included paging her PCP after hours if needed. I told her PCP before leaving that night that he might hear from her and that if she reached out, she would require hospitalization.
I arrived at work the following day, and her PCP shared with me that our patient had overdosed on medication, paged him, and was admitted to the unit.
He seemed forlorn.
I was both relieved by the news and confused by his reaction. I had hoped that she would choose a higher level of care than what we could provide her as an outpatient. I said: “This is good. She followed the plan.”
Her overdose was, of course, not part of the plan. She was struggling with several internal conflicts, including having mixed feelings about coming into the hospital; but, when the critical moment happened and she was faced with a decision to call for help or possibly die, she chose to call her PCP and have him paged as we had talked about.
I looked at her PCP. “You helped get her to where she needed to be.”
In the years of working side by side with medically trained colleagues, I have time and again needed to reframe for them that what they perceive to be a “failure” or a “crisis” is often a catalyst for change. The patient I comanaged with the PCP was a highly skilled caregiver and, as such, had been having a hard time asking for help. The hospitalization that her PCP facilitated allowed her to receive the care she needed and created an opportunity for family and friends to show up for her. Their support fed her, and she only made gains from that point on.
My training had taught me that respecting a patient’s autonomy was of the utmost importance. This instills confidence in patients as the authority in their lives. For a clinician to do this, a certain amount of helplessness must be tolerated. As I became better at identifying these moments of helplessness, feelings of failure and shame transformed.
Medical error
Sitting across from the PGY3 resident who I had met with weekly for the past 3 years, I thought about his error.
I thought about my phone call 4 nights earlier. My doctor was called at home by a lab technician, who never met their patients but was simply following protocol and alerted my doctor to the worsening number that she should have been aware of 9 months earlier.
Just like my doctor’s lapse of attention, my patient’s error was not a moment of helplessness to be tolerated. These were mistakes, and there was no way around it.
“People make mistakes.” I said simply.
We sat silently for a time.
I don’t remember who broke the silence. The conversation that followed was centered on our humanity and our capability for both compassion and fallibility. Afterward, I wondered who my doctor confided in and hoped she had a similar conversation.

Guidelines on GLP1RAs and continuous glucose monitors are among biggest news in diabetes
glucagonlike peptide-1 receptor agonists (GLP1RAs) and continuous glucose monitoring (CGM) technology. I am hoping my discussion about these major advances in this edition of Highlights will be helpful to those caring for patients with diabetes.
Tirzepatide
The first GLP1RA, exenatide, was released in April 2005. Since then, numerous daily and weekly drugs of this class have been developed. We’ve learned they are effective glucose lowering drugs, and the weekly agents dulaglutide and semaglutide have shown impressive weight reduction properties as well as cardiovascular benefits.
Secondary outcomes have also shown renal benefits to these agents, and studies for primary renal efficacy are pending. Due to all of these properties, the GLP1RAs are recommended as the first injectable for the treatment of type 2 diabetes, prior to insulin initiation.1
The next generation of these agents are a combination of a GLP1RA and a glucose-dependent insulinotropic polypeptide (GIP). Glucagonlike peptide-1 (GLP-1) stimulates insulin secretion, inhibits glucagon secretion, delays gastric emptying, and has central effects inducing satiety.
We now understand that GIP is the main incretin hormone in those without diabetes, causative of most of the incretin effects. But the insulin response after GIP secretion in type 2 diabetes is strongly reduced. It is now appreciated that this poor effect of GIP can be reduced when used in combination with a GLP1RA. This combination incretin, called by some a “twincretin,” is the basis for the drug tirzepatide which was approved by the Food and Drug Administration in May of 2022.
The data supporting this agent for both diabetes and obesity are impressive. For example, in a 40-week study with a baseline HbA1c of 8.0%, those randomized to tirzepatide at 5 mg, 10 mg, and 15 mg had HbA1c reductions of 1.87%, 1.89%, and 2.07% respectively.2 Over 81% at all doses had HbA1c levels less than 6.5% at 40 weeks.
For the 5-mg, 10-mg, and 15-mg doses, weight change from baseline was 7.9%, 9.3%, and 11.0% respectively. Like older GLP1RAs, gastrointestinal side effects were the main problem. For the three doses, 3%, 5%, and 7%, respectively, had to stop the drug, compared with the 3% who stopped taking the placebo. In another study, tirzepatide was noninferior or superior at all three doses compared with semaglutide 1 mg weekly.3
In a population without diabetes, with 40% of patients having prediabetes, weight loss percentages for the three doses were 15.0%, 19.5%, and 20.9% respectively.4 Discontinuation percentages due to side effects were 4%-7%. The exciting part is we now have a drug that approaches weight loss from bariatric surgery. The cardiovascular and renal outcome trials are now underway, but the enthusiasm for this drug is clear from the data.
Like other GLP1RAs, the key is to start low and go slowly. It is recommended to start tirzepatide at 2.5 mg four times a week, then increase to 5 mg. Due to gastrointestinal side effects, some patients will do better at the lower dose before increasing. For those switching from another GLP1RA, there are no data to guide us but, in my practice, I start those patients at 5 mg weekly.
Continuous glucose monitoring
Data continue to accumulate that this form of glycemic self-monitoring is effective to reduce HbA1c levels and minimize hypoglycemia in both type 1 and type 2 diabetes. The most important change to the 2022 American Diabetes Association (ADA) standards of care is recognizing CGM as level A evidence for those receiving basal insulin without mealtime insulin.5 There are four CGMs on the market, but most of the market uses the Dexcom G6 or the Libre 2. Both of these devices will be updated within the next few months to newer generation sensors.
While there are similarities and differences between the two devices, by late 2022 and early 2023 changes to both will reduce the dissimilarities.
The next generation Libre (Libre 3) will be continuous, and “scanning” will no longer be required. For those unable to get insurance to cover CGM, the Libre will continue to be more affordable than the Dexcom. Alerts will be present on both, but the Dexcom G7 will be approved for both the arm and the abdomen. The Dexcom also can communicate with several automated insulin delivery systems and data can be shared real-time with family members.
For clinicians just starting patients on this technology, my suggestion is to focus on one system so both the provider and staff can become familiar with it. It is key to review downloaded glucose metrics, in addition to the “ambulatory glucose profile,” a graphic overview of daily glycemia where patterns can be identified. It is also helpful to ask for assistance from endocrinologists who have experience with CGMs, in addition to the representatives of the companies.
COVID-19 and new-onset diabetes
From the beginning of the COVID 19 pandemic in 2020, it was clear that stress hyperglycemia and glucose dysregulation was an important observation for those infected. What was not known at the time is that for some, the hyperglycemia continued, and permanent diabetes ensued.
In one study of over 2.7 million U.S. veterans, men infected with COVID-19, but not women, were at a higher risk of new incident diabetes at 120 days after infection compared to no infection (odds ratio for men = 2.56).6
Another literature review using meta-analyses and cross-sectional studies concluded new-onset diabetes following COVID-19 infection can have a varied phenotype, with no risk factors, presenting from diabetic ketoacidosis to milder forms of diabetes.7
The current thought is that COVID-19 binds to the ACE2 and TMPRSS2 receptors which appear to be located on the beta-cells in the islet, resulting in insulin deficiency, in addition to the insulin resistance that seems to persist after the acute infection. Much more needs to be learned about this, but clinicians need to appreciate this appears to be a new form of diabetes and optimal treatments are not yet clear.

glucagonlike peptide-1 receptor agonists (GLP1RAs) and continuous glucose monitoring (CGM) technology. I am hoping my discussion about these major advances in this edition of Highlights will be helpful to those caring for patients with diabetes.
Tirzepatide
The first GLP1RA, exenatide, was released in April 2005. Since then, numerous daily and weekly drugs of this class have been developed. We’ve learned they are effective glucose lowering drugs, and the weekly agents dulaglutide and semaglutide have shown impressive weight reduction properties as well as cardiovascular benefits.
Secondary outcomes have also shown renal benefits to these agents, and studies for primary renal efficacy are pending. Due to all of these properties, the GLP1RAs are recommended as the first injectable for the treatment of type 2 diabetes, prior to insulin initiation.1
The next generation of these agents are a combination of a GLP1RA and a glucose-dependent insulinotropic polypeptide (GIP). Glucagonlike peptide-1 (GLP-1) stimulates insulin secretion, inhibits glucagon secretion, delays gastric emptying, and has central effects inducing satiety.
We now understand that GIP is the main incretin hormone in those without diabetes, causative of most of the incretin effects. But the insulin response after GIP secretion in type 2 diabetes is strongly reduced. It is now appreciated that this poor effect of GIP can be reduced when used in combination with a GLP1RA. This combination incretin, called by some a “twincretin,” is the basis for the drug tirzepatide which was approved by the Food and Drug Administration in May of 2022.
The data supporting this agent for both diabetes and obesity are impressive. For example, in a 40-week study with a baseline HbA1c of 8.0%, those randomized to tirzepatide at 5 mg, 10 mg, and 15 mg had HbA1c reductions of 1.87%, 1.89%, and 2.07% respectively.2 Over 81% at all doses had HbA1c levels less than 6.5% at 40 weeks.
For the 5-mg, 10-mg, and 15-mg doses, weight change from baseline was 7.9%, 9.3%, and 11.0% respectively. Like older GLP1RAs, gastrointestinal side effects were the main problem. For the three doses, 3%, 5%, and 7%, respectively, had to stop the drug, compared with the 3% who stopped taking the placebo. In another study, tirzepatide was noninferior or superior at all three doses compared with semaglutide 1 mg weekly.3
In a population without diabetes, with 40% of patients having prediabetes, weight loss percentages for the three doses were 15.0%, 19.5%, and 20.9% respectively.4 Discontinuation percentages due to side effects were 4%-7%. The exciting part is we now have a drug that approaches weight loss from bariatric surgery. The cardiovascular and renal outcome trials are now underway, but the enthusiasm for this drug is clear from the data.
Like other GLP1RAs, the key is to start low and go slowly. It is recommended to start tirzepatide at 2.5 mg four times a week, then increase to 5 mg. Due to gastrointestinal side effects, some patients will do better at the lower dose before increasing. For those switching from another GLP1RA, there are no data to guide us but, in my practice, I start those patients at 5 mg weekly.
Continuous glucose monitoring
Data continue to accumulate that this form of glycemic self-monitoring is effective to reduce HbA1c levels and minimize hypoglycemia in both type 1 and type 2 diabetes. The most important change to the 2022 American Diabetes Association (ADA) standards of care is recognizing CGM as level A evidence for those receiving basal insulin without mealtime insulin.5 There are four CGMs on the market, but most of the market uses the Dexcom G6 or the Libre 2. Both of these devices will be updated within the next few months to newer generation sensors.
While there are similarities and differences between the two devices, by late 2022 and early 2023 changes to both will reduce the dissimilarities.
The next generation Libre (Libre 3) will be continuous, and “scanning” will no longer be required. For those unable to get insurance to cover CGM, the Libre will continue to be more affordable than the Dexcom. Alerts will be present on both, but the Dexcom G7 will be approved for both the arm and the abdomen. The Dexcom also can communicate with several automated insulin delivery systems and data can be shared real-time with family members.
For clinicians just starting patients on this technology, my suggestion is to focus on one system so both the provider and staff can become familiar with it. It is key to review downloaded glucose metrics, in addition to the “ambulatory glucose profile,” a graphic overview of daily glycemia where patterns can be identified. It is also helpful to ask for assistance from endocrinologists who have experience with CGMs, in addition to the representatives of the companies.

Sexual function in transfeminine patients following gender-affirming vaginoplasty
For many patients, sexual function is an important component of a healthy quality of life.1 However, to many transgender individuals, their sexual organs are often a source of gender dysphoria, which can significantly inhibit sexual activity with their partners. Patients who seek gender-affirming surgery not only hope to have these feelings of dysphoria alleviated but also desire improvement in sexual function after surgery. While the medical and psychiatric criteria for patients seeking vaginoplasty procedures are well established by the World Professional Association for Transgender Health,2 there is little guidance surrounding the discourse surgeons should have regarding sexual function pre- and postsurgery.
Setting realistic expectations is one of the major challenges surgeons and patients alike face in preoperative and postoperative encounters. Patients not only are tasked with recovering from a major surgical procedure, but must also now learn their new anatomy, which includes learning how to urinate, maintain proper neovaginal hygiene, and experience sexual pleasure.
Given the permanence of these procedures and the possibility of loss of sexual function, the surgeon must ensure that patients truly comprehend the nature of the procedure and its complications. During the preoperative consultation, the surgeon must inquire about any desire for future fertility, discuss any history of pelvic radiation, epispadias, hypospadias, current erectile dysfunction, libido, comorbid medical conditions (such as diabetes or smoking), current sexual practices, and overall patient goals regarding their surgical outcome.
The vast majority of patients state they will experience a significant decrease in gender dysphoria with the removal of their current natal male genitalia.1 However, some patients have very specific preferences regarding the cosmetic appearance of vulvar structures. Others have more functional concerns about neovaginal depth and the ability to have receptive penetrative intercourse. It is important to note that not all transgender women have male partners. Furthermore, whether patients have male or female partners, some patients do not desire the ability to have penetrative intercourse and/or do not want to undergo the potential complications of a full-depth vaginoplasty. In these patients, offering a “shallow depth” vaginoplasty may be acceptable.
It is useful in the consultation to discuss a patient’s sexual partners and sexual practices in order to best determine the type of procedure that may be appropriate for a patient. In my practice, I emphasize that full-depth vaginoplasties require a lifelong commitment of dilation to maintain patency. Unlike cisgender women, patients must also douche to ensure appropriate vaginal hygiene. Regarding cosmetic preferences patients may have, it is essential to educate patients on the significant variation in the appearance of vulvar structures among both cisgender and transgender women.
During the surgical consultation, I review which structures from their natal genitalia are removed and which structures are utilized to create the neo–vulvar-vaginal anatomy. The testicles and spermatic cord are excised. The dorsal neurovascular bundle of the penile shaft and portion of the dorsal aspect of the glans penis are used to create the neoclitoris. A combination of penile shaft skin and scrotal skin is used to line the neovaginal canal. The erectile tissue of the penile shaft is also resected and the natal urethra is shortened and spatulated to create the urethral plate and urethral meatus. I also remind patients that the prostate remains intact during vaginoplasty procedures. Unless patients undergo the colonic interposition vaginoplasty and in some cases the peritoneal vaginoplasty, the neovaginal canal is not self-lubricating, nor will patients experience ejaculation after surgery. In the presurgical period, I often remind patients that the location of erogenous sensation after surgery will be altered and the method by which they self-stimulate will also be different. It is also essential to document whether patients can achieve satisfactory orgasms presurgically in order to determine adequate sexual function in the postoperative period.
It cannot be emphasized enough that the best predictor of unsatisfactory sexual function after genital gender-affirming surgery is poor sexual function prior to surgery.1,3
Retention of sexual function after gender-affirming genital surgery is common, with studies citing a range of 70%-90% of patients reporting their ability to regularly achieve an orgasm after surgery.1,4 In some cases, patients will report issues with sexual function after surgery despite having no prior history of sexual dysfunction. If patients present with complaints of postsurgical anorgasmia, the provider should rule out insufficient time for wound healing and resolution of surgery-site pain, and determine if there was an intraoperative injury to the neurovascular bundle or significant clitoral necrosis. A thorough genital exam should include a sensory examination of the neoclitoris and the introitus and neovaginal canal for signs of scarring, stenosis, loss of vaginal depth, or high-tone pelvic-floor dysfunction.
Unfortunately, if the neurovascular bundle is injured or if a patient experienced clitoral necrosis, the likelihood of a patient regaining sensation is decreased, although there are currently no studies examining the exact rates. It is also important to reassure patients that wound healing after surgery and relearning sexual function is not linear. I encourage patients to initially self-stimulate without a partner as they learn their new anatomy in order to remove any potential performance anxiety a partner could cause immediately after surgery. Similar to the approach to sexual dysfunction in cisgender patients, referral to a specialist in sexual health and/or pelvic floor physical therapy are useful adjuncts, depending on the findings from the physical exam and patient symptoms.

Retention of sexual function after gender-affirming genital surgery is common, with studies citing a range of 70%-90% of patients reporting their ability to regularly achieve an orgasm after surgery.1,4 In some cases, patients will report issues with sexual function after surgery despite having no prior history of sexual dysfunction. If patients present with complaints of postsurgical anorgasmia, the provider should rule out insufficient time for wound healing and resolution of surgery-site pain, and determine if there was an intraoperative injury to the neurovascular bundle or significant clitoral necrosis. A thorough genital exam should include a sensory examination of the neoclitoris and the introitus and neovaginal canal for signs of scarring, stenosis, loss of vaginal depth, or high-tone pelvic-floor dysfunction.
Unfortunately, if the neurovascular bundle is injured or if a patient experienced clitoral necrosis, the likelihood of a patient regaining sensation is decreased, although there are currently no studies examining the exact rates. It is also important to reassure patients that wound healing after surgery and relearning sexual function is not linear. I encourage patients to initially self-stimulate without a partner as they learn their new anatomy in order to remove any potential performance anxiety a partner could cause immediately after surgery. Similar to the approach to sexual dysfunction in cisgender patients, referral to a specialist in sexual health and/or pelvic floor physical therapy are useful adjuncts, depending on the findings from the physical exam and patient symptoms.

Exercise limitations in COPD – not everyone needs more inhalers
Chronic obstructive pulmonary disease (COPD) is defined by airway obstruction and alveolar damage caused by exposure to noxious air particles. The physiologic results include varying degrees of gas-exchange abnormality and mechanical respiratory limitation, often in the form of dynamic hyperinflation. There’s a third major contributor, though – skeletal muscle deconditioning. Only one of these abnormalities responds to inhalers.
When your patients with COPD report dyspnea or exercise intolerance, what do you do? Do you attempt to determine its character to pinpoint its origin? Do you quiz them about their baseline activity levels to quantify their conditioning? I bet you get right to the point and order a cardiopulmonary exercise test (CPET). That way you’ll be able to tease out all the contributors. Nah. Most likely you add an inhaler before continuing to rush through your COPD quality metrics: Vaccines? Check. Lung cancer screening? Check. Smoking cessation? Check.
The physiology of dyspnea and exercise limitation in COPD has been extensively studied. Work-of-breathing, dynamic hyperinflation, and gas-exchange inefficiencies interact with each other in complex ways to produce symptoms. The presence of deconditioning simply magnifies the existing abnormalities within the respiratory system by creating more strain at lower work rates. Acute exacerbations (AECOPD) and oral corticosteroids further aggravate skeletal muscle dysfunction.
The Global Strategy for the Diagnosis, Management, and Prevention of Chronic Obstructive Pulmonary Disease (GOLD) Report directs clinicians to use inhalers to manage dyspnea. If they’re already on one inhaler, they get another. This continues until they’re stabilized on a long-acting beta-agonist (LABA), long-acting muscarinic antagonist (LAMA), and an inhaled corticosteroid (ICS). The GOLD report also advises pulmonary rehabilitation for any patient with grade B through D disease. Unfortunately, the pulmonary rehabilitation recommendation is buried in the text and doesn’t appear within the popularized pharmacologic algorithms in the report’s figures.
The data for adding inhalers on top of each other to reduce AECOPD and improve overall quality of life (QOL) are good. However, although GOLD tells us to keep adding inhalers for the dyspneic patient with COPD, the authors acknowledge that this hasn’t been systematically tested. The difference? A statement doesn’t require the same formal, rigorous scientific analysis known as the GRADE approach. Using this kind of analysis, a recent clinical practice guideline by the American Thoracic Society found no benefit in dyspnea or respiratory QOL with step-up from inhaler monotherapy.
Inhalers won’t do anything for gas-exchange inefficiencies and deconditioning, at least not directly. A recent CPET study from the CanCOLD network found ventilatory inefficiency in 23% of GOLD 1 and 26% of GOLD 2-4 COPD patients. The numbers were higher for those who reported dyspnea. Skeletal muscle dysfunction rates are equally high.
Thus, dyspnea and exercise intolerance are major determinants of QOL in COPD, but inhalers will only get you so far. At a minimum, make sure you get an activity/exercise history from your patients with COPD. For those who are sedentary, provide an exercise prescription (really, it’s not that hard to do). If dyspnea persists despite LABA or LAMA monotherapy, clarify the complaint before doubling down. Finally, try to get the patient into a good pulmonary rehabilitation program. They’ll thank you afterwards.

A White female presented with pruritic, reticulated, erythematous plaques on the abdomen
It is characterized by pruritic, erythematous papules, papulovesicles, and vesicles that appear in a reticular pattern, most commonly on the trunk. The lesions are typically followed by postinflammatory hyperpigmentation (PIH).
Although PP has been described in people of all races, ages, and sexes, it is predominantly observed in Japan, often in female young adults. Triggers may include a ketogenic diet, diabetes mellitus, and pregnancy. Friction and contact allergic reactions to chrome or nickel have been proposed as exogenous trigger factors. Individual cases of Sjögren’s syndrome, Helicobacter pylori infections, and adult Still syndrome have also been associated with recurrent eruptions.
The diagnosis of PP is made both clinically and by biopsy. The histological features vary according to the stage of the disease. In early-stage disease, superficial and perivascular infiltration of neutrophils are prominent. Later stages are characterized by spongiosis and necrotic keratinocytes.
The first-line therapy for prurigo pigmentosa is oral minocycline. However, for some patients, doxycycline, macrolide antibiotics, or dapsone may be indicated. Adding carbohydrates to a keto diet may be helpful. In this patient, a punch biopsy was performed, which revealed an interface dermatitis with eosinophils and neutrophils, consistent with prurigo pigmentosa. The cause of her PP remains idiopathic. She was treated with 100 mg doxycycline twice a day, which resulted in a resolution of active lesions. The patient did have postinflammatory hyperpigmentation.

‘Stop pretending’ there’s a magic formula to weight loss
Is there a diet or weight-loss program out there that doesn’t work for those who stick with it during its first 12 weeks?
Truly, the world’s most backwards, upside-down, anti-science, nonsensical diets work over the short haul, fueled by the fact that short-term suffering for weight loss is a skill set that humanity has assiduously cultivated for at least the past 100 years. We’re really good at it!
It’s the keeping the weight off, though, that’s the hitch. Which leads me to the question, why are medical journals, even preeminent nonpredatory ones, publishing 12-week weight-loss program studies as if they have value? And does anyone truly imagine that after over 100 years of trying, there’ll be a short-term diet or program that’ll have the durable, reproducible results that no other short-term diet or program ever has?
Take this study published by Obesity: “Pragmatic implementation of a fully automated online obesity treatment in primary care.” It details a 12-week online, automated, weight-loss program that led completers to lose the roughly 5% of weight that many diets and programs see lost over their first 12 weeks. By its description, aside from its automated provision, the program sounds like pretty much the same boilerplate weight management advice and recommendations that haven’t been shown to lead large numbers of people to sustain long-term weight loss.
Participants were provided with weekly lessons which no doubt in some manner told them that high-calorie foods had high numbers of calories and should be minimized, along with other weight-loss secrets. Users were to upload weekly self-monitored weight, energy intake, and exercise minutes and were told to use a food diary. Their goal was losing 10% of their body weight by consuming 1,200-1,500 calories per day if they weighed less than 250 pounds (113 kg) and 1,500-1,800 calories if they weighed more than 250 pounds, while also telling them to aim for 200 minutes per week of moderate- to vigorous-intensity physical activity.
What was found was wholly unsurprising. Perhaps speaking to the tremendous and wide-ranging degrees of privilege that are required to prioritize intentional behavior change in the name of health, 79% of those who were given a prescription for the program either didn’t start it or stopped it before the end of the first week.
Of those who actually started the program and completed more than 1 week, despite having been selected as appropriate and interested participants by their physicians, only 20% watched all of the automated programs’ video lessons while only 32% actually bothered to submit all 12 weeks of weight data. Of course, the authors found that those who watched the greatest number of videos and submitted the most self-reported weights lost more weight and ascribed that loss to the program. What the authors did not entertain was the possibility that those who weren’t losing weight, or who were gaining, might simply be less inclined to continue with a program that wasn’t leading them to their desired outcomes or to want to submit their lack of loss or gains.
Short-term weight-loss studies help no one and when, as in this case, the outcomes aren’t even mediocre, and the completion and engagement rates are terrible, the study is still presented as significant and important. This bolsters the harmful stereotype that weight management is achievable by way of simple messages and generic goals. It suggests that it’s individuals who fail programs by not trying hard enough and that those who do, or who want it the most, will succeed. It may also lead patients and clinicians to second-guess the use of antiobesity medications, the current generation of which lead to far greater weight loss and reproducibility than any behavioral program or diet ever has.
The good news here at least is that the small percentage of participants who made it through this program’s 12 weeks are being randomly assigned to differing 9-month maintenance programs which at least will then lead to a 1-year analysis on the completers.
Why this study was published now, rather than pushed until the 1-year data were available, speaks to the pervasiveness of the toxic weight-biased notion that simple education will overcome the physiology forged over millions of years of extreme dietary insecurity.
Our food environment is a veritable floodplain of hyperpalatable foods, and social determinants of health make intentional behavior change in the name of health an unattainable luxury for a huge swath of the population.

Understanding the relationship between life satisfaction and cognitive decline
Every day, we depend on our working memory, spatial cognition, and processing speed abilities to optimize productivity, interpersonal interactions, and psychological wellbeing. These cognitive functioning indices relate closely with academic and work performance, managing emotions, physical fitness, and a sense of fulfillment in personal and work relationships. They are linked intimately to complex cognitive skills (van Dijk et al., 2020). It is thus imperative to identify modifiable predictors of cognitive functioning in the brain to protect against aging-related cognitive decline and maximize the quality of life.
A decline in life satisfaction can worsen cognitive functioning over long periods via lifestyle factors (e.g., suboptimal diet and nutrition, lack of exercise) (Ratigan et al., 2016). Inadequate engagement in these health-enhancing pursuits could build up inflammation in EF-linked brain areas, thus negatively impacting cognitive functioning in adulthood (Grant et al., 2009). Possible pathways include long-term wear and tear of the hypothalamic-pituitary axis and brain regions linked to executive functioning (Zainal and Newman, 2022a). These processes may deteriorate working memory, spatial cognition, and processing speed across time.
Similarly, it is plausible that a reduction in cognitive functioning may lead to a long-term decrease in life satisfaction. Working memory, processing speed, spatial cognition, and related capacities are essential to meaningful activities and feelings of gratification in personal and professional relationships and other spheres of health throughout life (Baumeister et al., 2007). These cognitive functioning markers safeguard against reduced life satisfaction by facilitating effective problem-solving, and choices (Swanson and Fung, 2016). For example, stronger working memory, processing speed, and related domains coincided with better tolerance for stress and trading off immediate rewards for long-term values and life goals (Hofmann et al., 2012). Therefore, reduction in cognitive functioning abilities could precede a future decline in life satisfaction.
Nonetheless, the literature on this topic has several limitations. Most of the studies have been cross-sectional (i.e., across a single time-point) and thus do not permit inferences between cause and effect (e.g., Toh et al., 2020). Also, most studies used statistical methods that did not differentiate between between-person (trait-like individual differences) and within-person (state-like) relations. Distinguishing within- and between-person relations is necessary because they may vary in magnitude and direction. The preceding theories emphasize change-to-future change relations within persons rather than between persons (Wright and Woods, 2020).
Clinical implications
Our recent work (Zainal and Newman, 2022b) added to the literature by using an advanced statistical method to determine the relations between change in life satisfaction and future change in cognitive functioning domains within persons. The choice of an advanced statistical technique minimizes biases due to the passage of time and assessment unreliability. It also adjusts for between-person effects (Klopack and Wickrama, 2020). Improving understanding of the within-person factors leading to the deterioration of cognitive functioning and life satisfaction is crucial given the rising rates of psychiatric and neurocognitive illnesses (Cui et al., 2020). Identifying these changeable risk factors can optimize prevention, early detection, and treatment approaches.
Specifically, we analyzed the publicly available Swedish Adoption/Twin Study of Aging (SATSA) dataset (Petkus et al., 2017). Their dataset comprised 520 middle- to older-aged twin adults without dementia. Participants provided data across 23 years with five time points. Each time lag ranged from 3 to 11 years. The analyses demonstrated that greater decreases in life satisfaction predicted larger future declines in processing speed, verbal working memory, and spatial cognition. Moreover, declines in verbal working memory and processing speed predicted a reduction in life satisfaction. However, change in spatial awareness did not predict change in life satisfaction.
Our study offers multiple theoretical perspectives. Scar theories propose that decreased life satisfaction and related mental health problems can compromise working memory, processing speed, and spatial cognition in the long term. This scarring process occurs through the buildup of allostatic load, such as increased biomarkers of chronic stress (e.g., cortisol) and inflammation (e.g., interleukin-6, C-reactive protein) (Fancourt and Steptoe, 2020; Zainal and Newman, 2021a). Also, findings suggest the importance of executive functioning domains to attain desired milestones and aspirations to enhance a sense of fulfillment (Baddeley, 2013; Toh and Yang, 2020). Reductions in these cognitive functioning capacities could, over time, adversely affect the ability to engage in daily living activities and manage negative moods.
Limitations of our study include the lack of a multiple-assessment approach to measuring diverse cognitive functioning domains. Also, the absence of cognitive self-reports is a shortcoming since perceived cognitive difficulties might not align with performance on cognitive tests. Relatedly, future studies should administer cognitive tests that parallel and transfer to everyday tasks. However, our study’s strengths include the robust findings across different intervals between study waves, advanced statistics, and the large sample size.
If future studies replicate a similar pattern of results, the clinical applications of this study merit attention. Mindfulness-based interventions can promote working memory, sustained awareness, and spatial cognition or protect against cognitive decline (Jha et al., 2019; Zainal and Newman, 2021b). Further, clinical science can profit from exploring cognitive-behavioral therapies to improve adults’ cognitive function or life satisfaction (Sok et al., 2021).
