Not all plant-based diets equal for CRC risk reduction
although the strength of the association may vary by race and ethnicity and tumor site, new research shows.
The “take-home message is that improving the quality of plant foods and reducing animal food consumption can help prevent colorectal cancer in men,” Jihye Kim told this news organization.
The findings suggest that “not all plant-based diets are the same with regard to colorectal cancer protection/risk,” said Ms. Kim, a professor in the College of Life and Sciences at Kyung Hee University in South Korea.
The study was published online in BMC Medicine.
The researchers investigated the risk for CRC in association with three plant-based dietary patterns defined by a priori indices: an overall plant-based diet index (PDI), a healthful plant-based diet index (hPDI), and an unhealthful plant-based diet index (uPDI).
All three indices negatively weigh animal foods but weigh plant foods differently depending on their nutritional quality.
Examples of foods contained in the hPDI include whole grains, fruits, vegetables, vegetable oils, nuts, legumes, tea, and coffee. Foods in the uPDI include refined grains, fruit juices, potatoes, and added sugars.
They calculated the PDI, hPDI, and uPDI using data from quantitative food frequency questionnaires provided by 79,952 men (mean age, 60 years at baseline) and 93,475 women (mean age, 59 years at baseline) in the Multiethnic Cohort Study.
During a mean follow-up of about 19 years, 4,976 participants developed CRC.
The plant-based diet indices were significantly inversely associated with the risk for CRC in men.
Researchers found that men with the greatest adherence to PDI and hPDI had a 24% (hazard ratio, 0.76) and 21% (HR, 0.79) lower risk for CRC, respectively, compared with men with the lowest adherence. No significant association was found between the risk for CRC in men and uPDI.
None of the plant-based diet indices was significantly associated with the risk for CRC in women, which could be because of different dietary habits between men and women, the researchers say.
In general, women consume more plant foods and less animal foods than men do, they point out.
In addition, women in the Multiethnic Cohort Study consumed higher amounts of healthy plant foods and lower amounts of less healthy plant foods compared with men, so they may not have further benefits with high scores of plant-based diet indices. Also, men are at higher risk for CRC than women are in general.
These findings suggest that the benefits from plant-based diets may vary by sex, race, and ethnicity, and anatomic subsite of tumor.
In men, the inverse association of overall PDI was greater in Japanese American, Native Hawaiian, and White groups than in African American and Latino groups, and for left colon and rectum tumors than for right colon tumors. The decreased risk with the hPDI was suggested across racial and ethnic groups and was observed for all tumor subsites.
“It was interesting to see that the association of a plant-based diet with CRC varied by race and ethnicity. It is not clear why. It could be nondietary lifestyle factors or genetic factors,” Ms. Kim told this news organization.
“We should investigate that more in the future,” Ms. Kim added.
By way of limitations, it’s possible that residual or unmeasured confounding might exist despite adjustment for key CRC risk factors, the researchers say. However, the subgroup analyses suggest that the impact of residual confounding due to body mass index, smoking status, and alcohol consumption was “minimal,” they note.
Another limitation is that the analysis was based on diet measured only at baseline, but dietary habits might change over time.
Overall, the findings “support that improving the quality of plant foods and reducing animal food consumption can help prevent colorectal cancer,” Ms. Kim and colleagues say.
The study was supported by the National Research Foundation of Korea and the U.S. National Cancer Institute and National Institutes of Health. The authors have declared no relevant conflicts of interest.

Florida doc dies by suicide after allegedly drugging and raping patients
according to a police statement.
A week later, a Collier County Sheriff’s deputy found Dr. Salata’s body near his Naples home with a gunshot wound to the head, according to police. The medical examiner later ruled it a suicide.
Dr. Salata co-owned Pura Vida Medical Spa in Naples with his wife Jill Salata, a certified family nurse practitioner. They specialized in cosmetic treatment and surgery.
Naples police said that they arrested Dr. Salata after two female patients accused the doctor of allegedly drugging and raping them while they were still unconscious.
Both victims described being given nitrous oxide, also called laughing gas, for sedation and pain from the cosmetic procedure. The first victim, age 51, said Dr. Salata prescribed alprazolam (Xanax) to take before the procedure and then also gave her nitrous oxide and tequila, causing her to black out, according to NBC2 News.
The second victim, age 72, told police that as the nitrous oxide was wearing off, she found Dr. Salata performing sexual intercourse. The victim felt shocked after the sedation subsided about what had taken place, contacted police, and submitted to a sexual assault examination, according to the police statement.
At Dr. Salata’s November 22 hearing before Judge Michael Provost, a prosecutor asked the judge whether Dr. Salata should surrender his firearms; Provost reportedly dismissed the idea.
“It is disappointing and frustrating that Dr. Salata has escaped justice,” said one victim’s attorney, Adam Horowitz, in a blog post. “Yet, we are relieved that no other women will be assaulted by Dr. Salata again. It took tremendous courage for my client to tell her truth. She was ready to hold him accountable in court.”
Horowitz says he plans to file a civil lawsuit on behalf of his client against Dr. Salata’s estate. The Naples police are continuing their investigation into the victims’ cases, which now includes a third woman, said spokesman Lt. Bryan McGinn.
Meanwhile, the Pura Vida Medical Spa has closed permanently and its website has been deleted. One reviewer named Soul F. wrote on the spa’s Yelp page: “And now may God have mercy on this rapist’s soul. Amen.”

Dapagliflozin reduces hospitalizations in patients with CKD
These findings add to a growing body of evidence supporting a range of positive benefits from dapagliflozin, including reduced risks of mortality, cardiovascular events, and kidney events, lead author Meir Schechter, MD, PhD, of the Hebrew University of Jerusalem and colleagues wrote in Annals of Internal Medicine.“Although cardiovascular and kidney outcomes with SGLT2 inhibitors have been studied extensively, there is a paucity of data evaluating the effects of SGLT2 inhibitors on hospitalizations for any cause.”
The findings are based on a post hoc analysis of the DAPA-CKD trial, which involved 4,304 patients with CKD in 21 countries. Patients were randomized in a 1:1 ratio to receive dapagliflozin 10 mg orally once a day or matching placebo. The present analysis quantified first hospitalizations for any cause, all hospitalizations, cause-specific hospitalizations, and several related outcomes.
After a median follow-up of 2.4 years, 28% of the population had been hospitalized a total of 2,072 times.
Compared with placebo, dapagliflozin significantly reduced risk of first hospitalization by 16% (hazard ratio, 0.84; 95% confidence interval, 0.75-0.94) and rate of all hospitalizations by 21% (rate ratio, 0.79; 95% CI, 0.70-0.89). These findings remained significant regardless of type 2 diabetes status, with significant benefits seen across reasons for admission, including renal/urinary disorders, cardiac disorders, neoplasms, and metabolism/nutrition disorders. In addition, dapagliflozin was associated with shorter mean time in hospital (2.3 vs. 2.8 days; P = .027) and longer time alive and out of hospital (354.9 vs. 351.7; P = .023).
“These findings highlight additional benefits of dapagliflozin beyond those seen for cardiovascular and kidney events, all-cause and cause-specific mortality, eGFR [estimated glomerular filtration rate] slope, and albuminuria and should be considered when evaluating the totality of evidence favoring provision of dapagliflozin to patients with CKD,” the investigators concluded.
Positive data, positive experiences
Shree Mulay, MD, a nephrologist in private practice in western Tennessee, said this study is “one of several other articles that already exist” demonstrating the broad benefits of SGLT2 inhibitors.
“The evidence is pretty substantial,” Dr. Mulay said in an interview. “I think SGLT2 inhibitors are the new statin of this era. ... I won’t be surprised if in the next year or 2 or 3 they truly become the standard of care.”
Dr. Mulay also speaks from experience working in both the chronic and acute setting, where he’s observed “some magical stuff happening” in patients started on SGLT2 inhibitors, especially those in heart failure who are fluid overloaded.
“It’s phenomenal stuff,” Dr. Mulay said. “You can really stabilize patients’ hemodynamics.”
In the private health care setting, he described widespread enthusiasm among nephrologists, although others still appear skeptical.
“It’s really our cardiology colleagues that I feel are underprescribing it,” Dr. Mulay said. “So, I’m kind of taking it on myself, when I see a heart failure patient, to go ahead and put them on this.”
It’s unclear why some cardiologists seem apprehensive, Dr. Mulay continued, although he suggested that unclear guidelines and a lack of first-hand experience may be to blame.
Nephrologists and cardiologists sometimes agree
In the academic arena, Leslie Gewin, MD, associate professor at Washington University in St. Louis and the John Cochran VA Hospital, also in St. Louis, has seen similar support for SGLT2 inhibitors among both nephrologists and cardiologists.
“We had a joint nephrology-cardiology medicine grand rounds at Wash U in St. Louis maybe 2 weeks ago,” Dr. Gewin said in an interview. “The cardiologists and nephrologists tag-teamed to present data about SGLT2 inhibitors, and we kind of joked that this was the one thing we both could get behind and support.”
Still, she has seen some reluctance among non-nephrology clinicians lacking SGLT2 experience, specifically when managing patients who have poor kidney function.
“There can be some hesitancy among physicians if the GFR is low,” Dr. Gewin said. “That’s where I’ve had to sort of push the envelope with non-nephrologists, saying: ‘Look, we feel pretty comfortable starting down to a GFR of about 20.’ ”
Early rises in creatinine may also spook providers, she noted.
“Sometimes, when we start SGLT2 inhibitors, the creatinine increases slightly, and the [primary care provider] gets concerned,” Dr. Gewin said. “We say: ‘No, this is expected. Don’t worry, hold the course, this is a good drug.’ ”
Like Dr. Mulay, Dr. Gewin said the present study offers further encouragement for the efficacy of this drug class. She also said sufficient data have been published to allay earlier concerns about potential safety signals, such as bone fractures and amputations.
“SGLT2 inhibitors seem to be a lot safer than what we initially had thought,” Dr. Gewin said. “That’s very encouraging.”
The study was funded by AstraZeneca. The investigators disclosed additional relationships with Bayer, Janssen, Gilead, and others. Dr. Gewin and Dr. Mulay disclosed no relevant conflicts of interest.

High cost and demand for old cancer drug sparks crisis
At Oregon Health and Science University, for example, an extensive algorithm now offers guidance through a thicket of alternative options, from adjusting doses and using substitutes to delaying treatment. Meanwhile, some institutions have enlisted ethicists and attorneys to guide their decisions on which patients will have to wait for potentially life-saving treatment.
Even as surgeons turn to alternatives, advocates for transplantation in hematology have warned about the potential for harm.
“This continued fludarabine shortage is forcing centers to use non–[Food and Drug Administration] approved lymphodepleting regimens that may negatively impact the success of a possibly lifesaving CAR-T therapy,” Brenda Sandmaier, MD, president of the Transplantation and Cellular Therapy American Society, and Jeffery Auletta, MD, a senior vice president with the National Marrow Donor, said in a June 30 letter to the FDA. The physicians added that they “request the FDA to take immediate action on this critical shortage. Many centers currently have no ability to purchase fludarabine through their suppliers and have no estimated time frame for return of availability. Other centers are limited to mere weeks of supply, with continued uncertainty of future availability.”
In October, less than 4 months after that letter was sent, one of the manufacturers of fludarabine – Areva Pharmaceuticals – marked up the price of fludarabine to $2,736 per vial, 10-20 times that of two other makers of the drug.
In new treatment era, fludarabine remains crucial
In 2015, ASH Clinical News – a publication of the American Society of Hematology – invited a pair of hematologists to discuss whether fludarabine is “dead” as a front-line treatment for chronic lymphocytic leukemia (CLL). “Fludarabine is not dead yet, but the data from those and other long-term trials may be the final nail in its coffin,” said Mitchell Smith, MD, PhD, who was then with Cleveland Clinic and now works for George Washington University.
Seven years later, the role of fludarabine as a long-term chemotherapeutic agent in blood cancer has definitely evolved. Just as oncologists predicted back in 2015, “the use of fludarabine declined for the primary management of CLL and other B cell malignancies, due to the development of targeted therapies such as BTK inhibitors, venetoclax, and other agents,” Memorial Sloan Kettering hematologic oncologist Anthony Mato, MD, said in an interview.
But the drug “remains a critical agent for conditioning the immune system for cellular therapies such as allogeneic stem cell transplantation and CAR-T cells,” Dr. Mato said.
Nirav Shah, MD, a hematologic oncologist at the Medical College of Wisconsin, explained in an interview that “conditioning” in the stem-cell transplant context refers to “wiping out” the immune system, allowing the donor’s stem cells to avoid rejection. “It’s a commonly used drug,” he said, “and shortage was not really a concern that people faced until this year.”
As shortage continues, price hike brings yet another hit
The first reports of fludarabine being in short supply surfaced about a year ago. According to a Nov. 2 update from the American Society of Health-System Pharmacists, five companies now manufacture fludarabine, and all of them report shortages. Areva, which dramatically raised its price, is accepting direct orders. Leucadia and Teva don’t know when the drug will be available; and Fresenius Kabi and Sagent expect availability in early 2023.
Areva, Leucadia, and Teva didn’t provide reasons for their shortages. Fresenius Kabi blamed increased demand, and Sagent pointed to manufacturing delays. Pfizer, another manufacturer, had a tiny market share and stopped making fludarabine in 2020, according to the pharmacist society.
In a May 12 press release, a company called Lannett announced it would take over U.S. distribution of fludarabine for Areva and suggested that the supply shortage would be lucrative: “While total U.S. sales for the 12 months ended March 2022 of Fludarabine Phosphate for injection, USP, 50 mg/2mL were approximately $4.9 million, according to IQVIA, the current market value is believed to be higher due to the recent market disruptions.”
“We were all shocked and outraged when Areva came out with the new, dramatically higher prices,” Bill Greene, PharmD, chief pharmaceutical officer at St. Jude Children’s Research Hospital, said in a recent interview.
In a prior interview, conducted during the summer of 2022, Dr. Greene addressed the topic of hematologic drug shortages. Back then he noted that he was seeking emergency supplies of fludarabine, since all five manufacturers reported having no stock available.
Interviewed again in November 2022, Dr. Greene noted that the hospital “had been able to stay ahead of the need and meet the needs of our patients” through arrangements with Teva and Fresenius Kabi. “In cases of patient need, we certainly are willing to pay a higher product price if that’s what it takes to get it – assuming the product is a quality product.”
The Medical College of Wisconsin’s Dr. Shah said insurers may refuse to cover the higher price, sticking medical institutions with the bill.
Alternatives abound, but do they suffice?
There is some good news on the fludarabine shortage front. Areva recently alerted providers that it was releasing fludarabine from non-FDA-approved suppliers with the agency’s permission, and Accord Healthcare said it received permission to sell fludarabine that was marketed in Canada.
Another option – oral fludarabine instead of the standard IV version – remains unavailable in the United States. According to the June letter to the FDA from the American Society for Transplantation and Cellular Therapy and National Marrow Donor Program, it “might be an appropriate alternative” and is available in Europe, Canada and Australia.
The letter warns that “transplant centers have also been forced to move away from fludarabine-based regimens and use alternative drugs such as cladribine or clofarabine, which are both significantly less studied and rely on single-center experience or limited phase II data. ... The limited availability of fludarabine is leading to the use of alternative regimens that are known to be more toxic or understudied alternatives with unknown long-term clinical effects or harms to patients.”
In a November 2022 report published in Transplantation and Cellular Therapy, Dr. Shah and colleagues noted that institutions are adopting strategies such as “(1) pharmacy dose banding and rounding down to save vials, even if a >5% reduction was required; (2) administering all dosing of fludarabine based not on actual body weight but on adjusted body weight; and (3) switching the billing of fludarabine from single-dose vials to billing by dose delivery.”
If the shortage continues, “it becomes necessary for centers to establish algorithms for management now,” they wrote. “Substitution of such agents as bendamustine and cladribine can be considered ... [and] another acceptable solution could be the substitution of clofarabine for fludarabine.”
Still, there are many unanswered questions. “The challenge is that these alternative regimens have not been extensively studied in a large population,” Dr. Shah said. “You have to be more mindful of potential side effects and risks, and the biggest concern is efficacy. Is changing the drug going to be detrimental to a patient’s outcome? To be honest, we don’t know the answer to that.”
Dr. Mato disclosed ties with TG Therapeutics, Pharmacyclics, AbbVie, Acerta, Adaptive Biotechnologies, AstraZeneca, BeiGene, BioPharma, BMS, Curio, Dava, DTRM, Genentech, Genmab, Janssen, Johnson & Johnson, LOXO, Medscape, Nurix, Octapharma, PER, PerView, and Pfizer. Dr. Greene and Dr. Shah have no disclosures.
At Oregon Health and Science University, for example, an extensive algorithm now offers guidance through a thicket of alternative options, from adjusting doses and using substitutes to delaying treatment. Meanwhile, some institutions have enlisted ethicists and attorneys to guide their decisions on which patients will have to wait for potentially life-saving treatment.

Green Mediterranean diet lowers visceral adipose tissue
according to a new analysis of the 18-month Dietary Intervention Randomized Controlled Trial Polyphenols Unprocessed (DIRECT-PLUS) trial.
The new results indicate that the green Mediterranean diet lowered visceral fat by twice as much as the standard Mediterranean diet (14% vs. 7%), reported Iris Shai, PhD, of Ben-Gurion University of the Negev in Be’er Sheva, Israel, and colleagues.
“This study may suggest an improved dietary protocol for treating visceral adiposity,” the authors wrote in their article, published recently in BMC Medicine.
“A healthy lifestyle is a strong basis for any weight-loss program. We learned from the results of our experiment that the quality of food is no less important than the number of calories consumed and the goal today is to understand the mechanisms of various nutrients, for example, positive ones such as the polyphenols, and negative ones such as empty carbohydrates and processed red meat, on the pace of fat cell differentiation and their aggregation in the viscera,” Dr. Shai said in a press release from Ben‐Gurion University.
“A 14% reduction in visceral fat is a dramatic achievement for making simple changes to your diet and lifestyle. Weight loss is an important goal only if it is accompanied by impressive results in reducing adipose tissue,” added coauthor Hila Zelicha, RD, PhD, also of Ben‐Gurion University of the Negev.
Previous randomized controlled trials have shown that dietary changes with a higher polyphenol content tend to produce better cardiometabolic outcomes and appear to mobilize particular ectopic fat depots, the researchers noted.
The main results of the DIRECT-PLUS trial were published in 2020 in Heart. Almost 300 participants with abdominal obesity/dyslipidemia were randomized to one of three diet groups (all accompanied by physical activity): standard healthy dietary guidelines (HDG), standard Mediterranean diet, and the so-called green Mediterranean diet. The mean age of participants was 51 years, and men comprised 88% of the study cohort.
Participants in both Mediterranean diet groups ate 28 grams/day of walnuts, which accounted for about 440 mg/day of polyphenols. Participants in the green Mediterranean group also ate 100 grams/day of frozen cubes of a Wolffia globosa (duckweed strain) plant green shake, and three to four cups/day of green tea, which contributed to consumption of 800 mg/day of polyphenols, and decreased red meat consumption.
Both the green and standard Mediterranean diet groups achieved similar weight loss (–6.2 kg and –5.4 kg) compared with the HDG group (–1.5 kg; P < .001). However, the green Mediterranean diet group had a greater reduction in waist circumference (–8.6 cm) than the standard Mediterranean diet group (–6.8 cm; P = .033) and HDG group (–4.3 cm; P < .001). Stratification by gender showed these differences were significant only among men.
Explaining the rationale for the study, the researchers noted that visceral adipose tissue accumulation is a key factor that differentiates metabolic healthy and unhealthy obese individuals, is closely related to the development of multiple cardiovascular risk factors, including hypertension, dyslipidemia, and type 2 diabetes, and is an independent marker of mortality.
Now, their latest data show the green Mediterranean diet group lost approximately twice as much visceral adipose tissue compared with the standard Mediterranean diet and HDG groups (−14.1%, −6.0%, and − 4.2%; P < .05 independent of weight loss, sex, waist circumference, or age).
Lower red meat consumption, greater dietary consumption of walnuts, Wolffia globosa, and green tea, increased urine urolithin A polyphenol, and elevated total plasma polyphenols were significantly associated with greater visceral adipose tissue loss (P < .05, multivariate models).
“A green Mediterranean diet enriched with polyphenols and decreased red meat consumption might serve as an improved version of the Mediterranean diet for targeted VAT reduction. Future studies are needed to explore the exact mechanisms of specific polyphenol-rich foods on visceral adiposity,” the study authors concluded.

Pediatric emergencies associated with unnecessary testing: AAP
Children seen for these conditions in emergency settings and even in primary care offices could experience avoidable pain, exposure to harmful radiation, and other harms, according to the group.
“The emergency department has the ability to rapidly perform myriad diagnostic tests and receive results quickly,” said Paul Mullan, MD, MPH, chair of the AAP’s Section of Emergency Medicine’s Choosing Wisely task force. “However, this comes with the danger of diagnostic overtesting.”
The five recommendations are as follows:
- Radiographs should not be obtained for children with bronchiolitis, croup, asthma, or first-time wheezing.
- Laboratory tests for screening should not be undertaken in the medical clearance process of children who require inpatient psychiatric admission unless clinically indicated.
- Laboratory testing or a CT scan of the head should not be ordered for a child with an unprovoked, generalized seizure or a simple febrile seizure whose mental status has returned to baseline.
- Abdominal radiographs should not be obtained for suspected constipation.
- Comprehensive viral panel testing should not be undertaken for children who are suspected of having respiratory viral illnesses.
The AAP task force partnered with Choosing Wisely Canada to create the recommendations. The list is the first of its kind to be published jointly by two countries, according to the release.
“We hope this Choosing Wisely list will encourage clinicians to rely on their clinical skills and avoid unnecessary tests,” said Dr. Mullan, who is also a physician at Children’s Hospital of the King’s Daughters and professor of pediatrics at Eastern Virginia Medical School, Norfolk.

Children seen for these conditions in emergency settings and even in primary care offices could experience avoidable pain, exposure to harmful radiation, and other harms, according to the group.
“The emergency department has the ability to rapidly perform myriad diagnostic tests and receive results quickly,” said Paul Mullan, MD, MPH, chair of the AAP’s Section of Emergency Medicine’s Choosing Wisely task force. “However, this comes with the danger of diagnostic overtesting.”
The five recommendations are as follows:
- Radiographs should not be obtained for children with bronchiolitis, croup, asthma, or first-time wheezing.
- Laboratory tests for screening should not be undertaken in the medical clearance process of children who require inpatient psychiatric admission unless clinically indicated.
- Laboratory testing or a CT scan of the head should not be ordered for a child with an unprovoked, generalized seizure or a simple febrile seizure whose mental status has returned to baseline.

FDA pulls U.S. authorization for Eli Lilly’s COVID drug bebtelovimab
the Food and Drug Administration said, citing it is not expected to neutralize the dominant BQ.1 and BQ.1.1 subvariants of Omicron.
The announcement on Nov. 30 takes away authorization from the last COVID-19 monoclonal antibody treatment, leaving Pfizer’s antiviral drug Paxlovid, Merck’s Lagevrio, and Gilead Sciences’ Veklury as treatments for the disease, besides convalescent plasma for some patients.
AstraZeneca’s monoclonal antibody Evusheld is also authorized for protection against COVID-19 infection in some people.
Eli Lilly and its authorized distributors have paused commercial distribution of the monoclonal antibody until further notice from the agency, while the U.S. government has also paused fulfillment of any pending requests under its scheme to help uninsured and underinsured Americans access the drug.
The drug, which was discovered by Abcellera and commercialized by Eli Lilly, received an authorization from the FDA in February.
BQ.1 and BQ.1.1 have become the dominant strains in the United States after a steady increase in prevalence over the last 2 months, surpassing Omicron’s BA.5 subvariant, which had driven cases earlier in the year.
The subvariants accounted for around 57% of the cases nationally, as per government data last week.

Confirmed: Amyloid, tau levels rise years before Alzheimer’s onset
“Our results confirm accelerated biomarker changes during preclinical AD and highlight the important role of amyloid levels in tau accelerations,” the investigators note.
“These data may suggest that there is a short therapeutic window for slowing AD pathogenesis prior to the emergence of clinical symptoms – and that this window may occur after amyloid accumulation begins but before amyloid has substantial impacts on tau accumulation,” study investigator Corinne Pettigrew, PhD, department of neurology, Johns Hopkins University School of Medicine, Baltimore, told this news organization.
The study was published online in Alzheimer’s and Dementia.
Novel long-term CSF data
The study builds on previous research by examining changes in cerebrospinal fluid (CSF) biomarkers over longer periods than had been done previously, particularly among largely middle-aged and cognitively normal at baseline individuals.
The researchers examined changes in amyloid beta (Aβ) 42/Aβ40, phosphorylated tau181 (p-tau181), and total tau (t-tau) in CSF over an average of 10.7 years (and up to 23 years) among 278 individuals who were largely middle-aged persons who were cognitively normal at baseline.
“To our knowledge, no prior study among initially cognitively normal, primarily middle-aged individuals has described CSF AD biomarker changes over this duration of follow-up,” the researchers write.
During follow-up, 94 individuals who initially had normal cognition developed mild cognitive impairment (MCI).
Lower baseline levels of amyloid were associated with greater increases in tau (more strongly in men than women), while accelerations in tau were more closely linked to onset of MCI, the researchers report.
Among individuals who developed MCI, biomarker levels were more abnormal and tau increased to a greater extent prior to the onset of MCI symptoms, they found.
Clear impact of APOE4
The findings also suggest that among APOE4 carriers, amyloid onset occurs at an earlier age and rates of amyloid positivity are higher, but there are no differences in rates of change in amyloid over time.
“APOE4 genetic status was not related to changes in CSF beta-amyloid after accounting for the fact that APOE4 carriers have higher rates of amyloid positivity,” said Dr. Pettigrew.
“These findings suggest that APOE4 genetic status shifts the age of onset of amyloid accumulation (with APOE4 carriers having an earlier age of onset compared to non-carriers), but that APOE4 is not related to rates of change in CSF beta-amyloid over time,” she added.
“Thus, cognitively normal APOE4 carriers may be in more advanced preclinical AD stages at younger ages than individuals who are not APOE4 carriers, which is likely relevant for optimizing clinical trial recruitment strategies,” she said.
Funding for the study was provided by the National Institutes of Health. Dr. Pettigrew has disclosed no relevant financial relationships. The original article contains a complete list of author disclosures.

RSV surge stuns parents and strains providers, but doctors offer help
RSV cases peaked in mid-November, according to the latest Centers for Disease Control and Prevention data, with RSV-associated hospitalizations in the United States among patients 0-4 years having maxed out five times higher than they were at the same time in 2021. These surges strained providers and left parents scrambling for care. Fortunately, pediatric hospitalizations appear to be subsiding.
In interviews, the parents of the child who had a severe case of RSV reflected on their son’s bout with the illness, and doctors described challenges to dealing with the surge in RSV cases this season. The physicians also offered advice on how recognize and respond to future cases of the virus.
Sebastian Witt’s story
“I didn’t even know what RSV was,” said Malte Witt, whose son, Sebastian, 2, was recently hospitalized for RSV in Denver.
Mr. Witt and his wife, Emily Witt, both 32, thought they were dealing with a typical cold until Sebastian’s condition dramatically deteriorated about 36 hours after symptom onset.
“He basically just slumped over and collapsed, coughing uncontrollably,” Mr. Witt said in an interview. “He couldn’t catch his breath.”
The Witts rushed Sebastian to the ED at Children’s Hospital Colorado, expecting to see a doctor immediately. Instead, they spent the night in an overcrowded waiting room alongside many other families in the same situation.
“There was no room for anyone to sit anywhere,” Mr. Witt said. “There were people sitting on the floor. I counted maybe six children hooked up to oxygen when we walked in.”
After waiting approximately 45 minutes, a nurse checked Sebastian’s oxygen saturation. The readings were 79%-83%. This range is significantly below thresholds for supplemental oxygen described by most pediatric guidelines, which range from 90 to 94%.
The nurse connected Sebastian to bottled oxygen in the waiting room, and a recheck 4 hours later showed that his oxygen saturation had improved.
But the improvement didn’t last.
“At roughly hour 10 in the waiting room – it was 4 in the morning – you could tell that Seb was exhausted, really not acting like himself,” Mr. Witt said. “We thought maybe it’s just late at night, he hasn’t really slept. But then Emily noticed that his oxygen tank had run out.”
Mr. Witt told a nurse, and after another check revealed low oxygen saturation, Sebastian was finally admitted.
Early RSV surge strains pediatric providers
With RSV-associated hospitalizations peaking at 48 per 100,000 children, Colorado has been among the states hardest hit by the virus. New Mexico – where hospitalizations peaked at 56.4 per 100,000 children – comes in second. Even in states like California, where hospitalization rates have been almost 10-fold lower than New Mexico, pediatric providers have been stretched to their limits.
“Many hospitals are really being overwhelmed with admissions for RSV, both routine RSV – relatively mild hospitalizations with bronchiolitis – as well as kids in the ICU with more severe cases,” said Dean Blumberg, MD, chief of the division of pediatric infectious diseases at UC Davis Health, Sacramento, said in an interview.
Dr. Blumberg believes the severity of the 2022-2023 RSV season is likely COVID related.
“All community-associated respiratory viral infections are out of whack because of the pandemic, and all the masking and social distancing that was occurring,” he said.
This may also explain why older kids are coming down with more severe cases of RSV.
“Some children are getting RSV for the first time as older children,” Dr. Blumberg said, noting that, historically, most children were infected in the first 2 years of life. “There are reports of children 3 or 4 years of age being admitted with their first episode of RSV because of the [COVID] pandemic.”
This year’s RSV season is also notable for arriving early, potentially catching the community off guard, according to Jennifer D. Kusma, MD, a primary care pediatrician at Ann & Robert H. Lurie Children’s Hospital of Chicago.
“People who should have been protected often weren’t protected yet,” Dr. Kusma said in an interview.
Treatments new, old, and unproven
On Nov. 17, in the midst of the RSV surge, the American Academy of Pediatrics issued updated guidance for palivizumab, an RSV-targeting monoclonal antibody labeled for children at risk of severe RSV, including those with pre-existing lung or heart conditions, and infants with a history of premature birth (less than or equal to 35 weeks’ gestational age).
“If RSV disease activity persists at high levels in a given region through the fall and winter, the AAP supports providing more than five consecutive doses of palivizumab to eligible children,” the update stated.
Insurance companies appear to be responding in kind, covering additional doses for children in need.
“[Payers] have agreed that, if [palivizumab] needs to be given for an additional month or 2 or 3, then they’re making a commitment that they’ll reimburse hospitals for providing that,” Dr. Blumberg said.
For ineligible patients, such as Sebastian, who was born prematurely at 36 weeks – 1 week shy of the label requirement – treatment relies upon supportive care with oxygen and IV fluids.
At home, parents are left with simpler options.
Dr. Blumberg and Dr. Kusma recommended keeping children hydrated, maintaining humidified air, and using saline nose drops with bulb suction to clear mucus.
In the Witts’ experience, that last step may be easier said than done.
“Every time a nurse would walk into the room, Sebastian would yell: ‘Go away, doctor! I don’t want snot sucker!’” Mr. Witt said.
“If you over snot-suck, that’s really uncomfortable for the kid, and really hard for you,” Ms. Witt said. “And it doesn’t make much of a difference. It’s just very hard to find a middle ground, where you’re helping and keeping them comfortable.”
Some parents are turning to novel strategies, such as nebulized hypertonic saline, currently marketed on Amazon for children with RSV.
Although the AAP offers a weak recommendation for nebulized hypertonic saline in children hospitalized more than 72 hours, they advise against it in the emergency setting, citing inconsistent findings in clinical trials.
To any parents tempted by thousands of positive Amazon reviews, Dr. Blumberg said, “I wouldn’t waste my money on that.”
Dr. Kusma agreed.
“[Nebulized hypertonic saline] can be irritating,” she said. “It’s saltwater, essentially. If a parent is in the position where they’re worried about their child’s breathing to the point that they think they need to use it, I would err on the side of calling your pediatrician and being seen.”
Going in, coming home
Dr. Kusma said parents should seek medical attention if a child is breathing faster and working harder to get air. Increased work of breathing is characterized by pulling of the skin at the notch where the throat meets the chest bone (tracheal tugging), and flattening of the belly that makes the ribcage more prominent.
Mr. Witt saw these signs in Sebastian. He knew they were significant, because a friend who is a nurse had previously shown him some examples of children who exhibited these symptoms online.
“That’s how I knew that things were actually really dangerous,” Mr. Witt said. “Had she not shown me those videos a month and a half before this happened, I don’t know that we would have hit the alarm bell as quickly as we did.”
After spending their second night and the following day in a cramped preoperative room converted to manage overflow from the emergency department, Sebastian’s condition improved, and he was discharged. The Witts are relieved to be home, but frustrations from their ordeal remain, especially considering the estimated $5,000 in out-of-pocket costs they expect to pay.
“How is this our health care system?” Ms. Witt asked. “This is unbelievable.”
An optimistic outlook
RSV seasons typically demonstrate a clear peak, followed by a decline through the rest of the season, suggesting better times lie ahead; however, this season has been anything but typical.
“I’m hopeful that it will just go away and stay away,” Dr. Kusma said, citing this trend. “But I can’t know for sure.”
To anxious parents, Dr. Blumberg offered an optimistic view of RSV seasons to come.
“There’s hope,” he said. “There are vaccines that are being developed that are very close to FDA approval. So, it’s possible that this time next year, we might have widespread RSV vaccination available for children so that we don’t have to go through this nightmare again.”
Dr. Blumberg and Dr. Kusma disclosed no relevant conflicts of interest.

“At roughly hour 10 in the waiting room – it was 4 in the morning – you could tell that Seb was exhausted, really not acting like himself,” Mr. Witt said. “We thought maybe it’s just late at night, he hasn’t really slept. But then Emily noticed that his oxygen tank had run out.”
Mr. Witt told a nurse, and after another check revealed low oxygen saturation, Sebastian was finally admitted.
Early RSV surge strains pediatric providers
With RSV-associated hospitalizations peaking at 48 per 100,000 children, Colorado has been among the states hardest hit by the virus. New Mexico – where hospitalizations peaked at 56.4 per 100,000 children – comes in second. Even in states like California, where hospitalization rates have been almost 10-fold lower than New Mexico, pediatric providers have been stretched to their limits.
“Many hospitals are really being overwhelmed with admissions for RSV, both routine RSV – relatively mild hospitalizations with bronchiolitis – as well as kids in the ICU with more severe cases,” said Dean Blumberg, MD, chief of the division of pediatric infectious diseases at UC Davis Health, Sacramento, said in an interview.
Dr. Blumberg believes the severity of the 2022-2023 RSV season is likely COVID related.
“All community-associated respiratory viral infections are out of whack because of the pandemic, and all the masking and social distancing that was occurring,” he said.
This may also explain why older kids are coming down with more severe cases of RSV.
“Some children are getting RSV for the first time as older children,” Dr. Blumberg said, noting that, historically, most children were infected in the first 2 years of life. “There are reports of children 3 or 4 years of age being admitted with their first episode of RSV because of the [COVID] pandemic.”
This year’s RSV season is also notable for arriving early, potentially catching the community off guard, according to Jennifer D. Kusma, MD, a primary care pediatrician at Ann & Robert H. Lurie Children’s Hospital of Chicago.
“People who should have been protected often weren’t protected yet,” Dr. Kusma said in an interview.
Treatments new, old, and unproven
On Nov. 17, in the midst of the RSV surge, the American Academy of Pediatrics issued updated guidance for palivizumab, an RSV-targeting monoclonal antibody labeled for children at risk of severe RSV, including those with pre-existing lung or heart conditions, and infants with a history of premature birth (less than or equal to 35 weeks’ gestational age).
“If RSV disease activity persists at high levels in a given region through the fall and winter, the AAP supports providing more than five consecutive doses of palivizumab to eligible children,” the update stated.
Insurance companies appear to be responding in kind, covering additional doses for children in need.
“[Payers] have agreed that, if [palivizumab] needs to be given for an additional month or 2 or 3, then they’re making a commitment that they’ll reimburse hospitals for providing that,” Dr. Blumberg said.
For ineligible patients, such as Sebastian, who was born prematurely at 36 weeks – 1 week shy of the label requirement – treatment relies upon supportive care with oxygen and IV fluids.
At home, parents are left with simpler options.
Dr. Blumberg and Dr. Kusma recommended keeping children hydrated, maintaining humidified air, and using saline nose drops with bulb suction to clear mucus.
In the Witts’ experience, that last step may be easier said than done.
“Every time a nurse would walk into the room, Sebastian would yell: ‘Go away, doctor! I don’t want snot sucker!’” Mr. Witt said.
“If you over snot-suck, that’s really uncomfortable for the kid, and really hard for you,” Ms. Witt said. “And it doesn’t make much of a difference. It’s just very hard to find a middle ground, where you’re helping and keeping them comfortable.”
Some parents are turning to novel strategies, such as nebulized hypertonic saline, currently marketed on Amazon for children with RSV.
Although the AAP offers a weak recommendation for nebulized hypertonic saline in children hospitalized more than 72 hours, they advise against it in the emergency setting, citing inconsistent findings in clinical trials.
To any parents tempted by thousands of positive Amazon reviews, Dr. Blumberg said, “I wouldn’t waste my money on that.”
Dr. Kusma agreed.
“[Nebulized hypertonic saline] can be irritating,” she said. “It’s saltwater, essentially. If a parent is in the position where they’re worried about their child’s breathing to the point that they think they need to use it, I would err on the side of calling your pediatrician and being seen.”
Going in, coming home
Dr. Kusma said parents should seek medical attention if a child is breathing faster and working harder to get air. Increased work of breathing is characterized by pulling of the skin at the notch where the throat meets the chest bone (tracheal tugging), and flattening of the belly that makes the ribcage more prominent.
Mr. Witt saw these signs in Sebastian. He knew they were significant, because a friend who is a nurse had previously shown him some examples of children who exhibited these symptoms online.
“That’s how I knew that things were actually really dangerous,” Mr. Witt said. “Had she not shown me those videos a month and a half before this happened, I don’t know that we would have hit the alarm bell as quickly as we did.”
After spending their second night and the following day in a cramped preoperative room converted to manage overflow from the emergency department, Sebastian’s condition improved, and he was discharged. The Witts are relieved to be home, but frustrations from their ordeal remain, especially considering the estimated $5,000 in out-of-pocket costs they expect to pay.
“How is this our health care system?” Ms. Witt asked. “This is unbelievable.”
An optimistic outlook
RSV seasons typically demonstrate a clear peak, followed by a decline through the rest of the season, suggesting better times lie ahead; however, this season has been anything but typical.
“I’m hopeful that it will just go away and stay away,” Dr. Kusma said, citing this trend. “But I can’t know for sure.”
To anxious parents, Dr. Blumberg offered an optimistic view of RSV seasons to come.
“There’s hope,” he said. “There are vaccines that are being developed that are very close to FDA approval. So, it’s possible that this time next year, we might have widespread RSV vaccination available for children so that we don’t have to go through this nightmare again.”
Dr. Blumberg and Dr. Kusma disclosed no relevant conflicts of interest.
Flu, RSV infecting children at staggering rates
There has been no ebb in the flurry of respiratory illnesses infecting America’s youngest children. More pediatric wards across the country are announcing crises as beds reach capacity, the pediatric death toll jumped significantly in the past week, and sometimes children are being infected with more than one virus at a time.
In Oregon, for example, the governor announced an official state of emergency to help hospitals deal with the surge of respiratory viruses. Doernbecher Children’s Hospital in Portland, which houses half of all pediatric ICU beds statewide, moved to “crisis mode” and said every pediatric ICU bed was full, Oregon Public Broadcasting reported.
Last month, pediatricians nationwide called for a similar emergency declaration from the federal government to help them respond to the wave of illnesses, which include influenza and respiratory syncytial virus (RSV).
“What’s concerning to us are not only the number of infections, but the severity of these infections, leading to a high number of emergency room visits and hospitalizations,” pediatric infectious disease expert Oscar G. Gómez-Duarte, MD, PhD, said in a news release.
Five more pediatric deaths due to the flu were logged by the CDC in the past week, bringing the total for pediatric flu deaths this season to 12. Nearly 21 per 100,000 children ages 4 and under are being hospitalized for the flu, which is double the rate for children ages 5-17. Last year at this time, fewer than 1 child under age 4 per 100,000 were being hospitalized for the flu.
RSV rates are also stunningly high.
“If we look at CDC data, the RSV hospitalization rate is 10 times higher than usual for this point in the season,” American Medical Association Vice President Andrea Garcia, JD, said in this week’s AMA podcast. “And 171 out of every 100,000 infants younger than 6 months were hospitalized with RSV for the week ending Nov. 12. That is more than double the RSV hospitalization rate for newborns last year and seven times the rate in 2018, which is the last complete season we saw before the pandemic.”
Dr. Gómez-Duarte said hospitals are admitting children with respiratory illnesses who had otherwise been healthy, and sometimes they are even seeing patients with more than one illness.
“Yes, some children are getting what we call coinfections, where they become infected with more than one virus at a time. In some instances, a child becomes initially infected with flu, begins to recover, and subsequently comes down with rhinovirus (a common cold virus), RSV, or any other respiratory virus,” he said. “These coinfections tend to be more severe than when the child just has one infection.”
