If a saphenous graft is available, treat limb threatening ischemia surgically
CHICAGO – In patients with chronic limb-threatening ischemia (CLTI) and a usable saphenous vein segment, a surgical procedure leads to better outcomes than an endovascular approach, according results of the multinational randomized BEST-CLI trial.
In that study, conducted with two cohorts, the advantage of surgery was limited to the group with an available saphenous vein, but in this group the advantage over an endovascular approach was substantial, according to Alik Farber, MD, chief of vascular and endovascular surgery at Boston University.
“Bypass with adequate saphenous vein should be offered as a first-line treatment option for suitable candidates with CLTI as part of fully informed, shared decision-making,” Dr. Farber stated in presenting the results at the annual scientific sessions of the American Heart Association.
The study pursued two hypotheses, which is why CLTI patients were divided into two cohorts. For cohort 1, which was limited to CLTI patients with an available saphenous vein, it was predicted that surgery would be better than an endovascular approach. For cohort 2, which enrolled patients who needed an alternative conduit, the hypothesis was that endovascular procedures would prove superior.
The study confirmed the first hypothesis, but there was no difference between the two approaches for the composite primary outcome of major adverse limb events (MALE) in the second cohort.
Saphenous vein availability determined cohort
Candidates for the BEST-CLI (Best Endovascular versus Best Surgical Therapy in Patients with CLTI) trial had to have CLTI producing severe ischemia and to be judged by both surgeons and cardiovascular specialists to be candidates for both types of interventions. Eligible patients were then enrolled in cohort 1 if the saphenous vein was considered the best conduit on imaging. If not, they were enrolled in cohort 2.
Patients were randomized to undergo surgical or endovascular repair only after the cohort was assigned. The primary composite MALE endpoint consisted of an adjudicated first major reintervention, such as new bypass or thrombectomy, an above-the-ankle amputation, or death from any cause.
In cohort 1, the primary composite MALE endpoint was reached in 42.6% of those in surgical arm and 57.4% in the endovascular arm, translating into a 32% relative risk reduction (hazard ratio, 0.68; P < .001) in favor of surgery at the end of a median of 2.7 years of follow-up.
The main advantage was the difference in reinterventions. The lower rate in the surgical group (9.2% vs. 23.5%), translated into a 65% relative risk reduction for this endpoint (HR, 035; P < .001).
The reduction in above-ankle amputations in the surgical group (10.4% vs. 14.9%) was also significant (HR, 0.73; P = .04), but the reduction in all-cause mortality (33.0% vs. 37.6%) was not (HR, 0.98; P = .81).
BEST-CLI involved 150 sites in North America, Europe, and New Zealand. Cohort 1, which randomized 1,434 patients, was the larger of the two. In the second cohort, only 396 patients were randomized, which Dr. Farber said “might have been underpowered.”
The results were published in the New England Journal of Medicine simultaneously with presentation of the results at the meeting.
After a median follow-up of 1.6 years in cohort 2, the slightly lower proportion of patients who reached the composite MALE endpoint in the surgical group relative to the endovascular group (42.8% vs. 47.7%) did not translate into a significant advantage (HR, 0.79; P = .12).
For the individual components, the lower rate of reinterventions in the surgical arm (14.4% vs. 25.6%) did reach statistical significance (HR, 0.47; P = .002), but both amputation (14.9% vs. 14.1%) and all-cause death (26.3% vs. 24.1%) were numerically but not significantly higher in the surgical group.
The primary safety endpoint was major adverse cardiovascular events (MACE). This was not significantly different in either cohort. There were also no major differences between groups in the risk of perioperative complications.
Level 1 evidence provided for intervention choice
Overall, BEST-CLI showed that both surgical and endovascular revascularizations are effective and safe, according to Dr. Farber. As a result, he suggested that both can be considered even if a saphenous vein is available when specific patient characteristics make one more attractive than another.
Yet, in a general population with an available saphenous vein, these data provide “level 1 evidence” that a surgical approach should be the dominant choice, he added.
A quality of life (QOL) substudy of BEST-CLI did not challenge this conclusion. Rather, the main finding was that restoring circulation by either approach has a major favorable impact on patient well-being, according to Matthew Menard, MD, codirector of endovascular surgery at Brigham and Women’s Hospital, Boston.
In this substudy, presented separately from the primary BEST-CLI results, that analysis confirmed that baseline QOL was extremely poor, whether measured with a disease specific instrument such as VascuQol, or generic instruments, such as SF-12.
Surgical or endovascular treatment produced clinically meaningful and sustained improvements in every QOL measure employed, according to Dr. Menard, and this was true in either cohort.
Results not necessarily relevant to all
These data are likely relevant to the patients evaluated, but “it is important to consider who made it into this trial,” according to Naomi M. Hamburg, MD, section chief of vascular biology at Boston University.
Not least, patients had to be candidates for either surgical or endovascular repair to get into the study, omitting those patients not deemed by the investigators to be suited for either.
In addition, Dr. Hamburg pointed out that there was a low enrollment of Blacks (20%) and women (28%), two groups for whom CTLI is a common condition.
Lastly, Dr Hamburg questioned whether specific types of anatomy might be better suited to one procedure relative to another, a variable not considered in this study. Reassured by Dr. Farber that this will be explored in subsequent analyses of BEST-CLI data, Dr. Hamburg expressed interest in learning the results.
Dr. Hamburg was among those who spoke about the growing urgency to optimize strategies for early diagnosis and treatment of CTLI. She plugged the PAD National Action Plan as one of the efforts to thwart the coming wave of CTLI expected from the steep climb in the prevalence of diabetes in the United States.
Dr. Farber reported a financial relationship with Sanifit Therapeutics. The study was funded by the National Heart, Lung, and Blood Institute, but received additional support from multiple pharmaceutical companies. Dr. Menard reported a financial relationship with Janssen Pharmaceuticals. Dr. Hamburg reported financial relationships with Acceleron Pharma, Merck, NovoNordisk, and Sanifit.

Phase 3 trial yields better way to predict MCL outcomes
Single assessments of minimal residual disease (MRD) effectively prognosticated relapse risks in patients with MCL treated with chemoimmunotherapy and transplantation, according to investigators.
However, by evaluating MRD status over time, disease progression could be predicted with greater certainty, according to study lead author Simone Ferrero, MD, assistant professor of hematology at the University of Torino (Italy).
“The most important message is that MRD is predictive, and then in particular, if you want to study MRD, you have to do a repeated MRD analysis in order to have a better picture of the disease course and to determine the prognosis of each single patient,” Dr. Ferrero said in an interview.
Predictive power of MRD
Piers Blombery, MBBS, hematologist and medical lead of the Molecular Hematology Laboratory at Peter MacCallum Cancer Centre in Melbourne, said these study findings illustrate how the predictive power of MRD is enhanced when it is evaluated longitudinally, over the course of a patient’s disease.
“We need to be prepared to have models of MRD that take into account changes in values across time,” Dr. Blombery said in an interview.
“Conventionally, we have looked at single time points in disease, such as end of induction therapy or post autologous stem cell transplant,” said Dr. Blombery, “but we may need now to have more complex models that can integrate values over multiple time points to guide intervention.”
Dr. Blombery, who was not involved in the study, coauthored an independent commentary on the results that was also published in Blood.
Tools to predict relapse
Although initial MCL treatment is often effective, most patients will relapse. Accordingly, there have been considerable efforts to develop tools that identify patients at high risk of relapse, according to Dr. Ferrero and coauthors.
Among these tools is the Mantle Cell Lymphoma International Prognostic Index (MIPI), which risk-stratifies patients on the basis of age, performance status, leukocyte count, and lactate dehydrogenase.
More recently, in several published studies, MRD has been demonstrated a high predictive value in MCL. However, the best way to evaluate MRD has yet to be worked out. There are differences in testing methods, sampling (that is, bone marrow versus peripheral blood), and time points that are evaluated.
In some recent studies, investigators have pooled MRD samples taken at different time points, according to Dr. Ferrero and colleagues. Furthermore, there had been no prior systematic attempts to compare the prognostic performance of MRD data evaluated over time, as compared with MRD at a single time point.
Exploiting MRD data
The analysis by Dr. Ferrero and coauthors, which appears in the journal Blood, is a substudy of FIL MCL0208, a recent multicenter, randomized, phase 3 clinical trial that demonstrated the benefit of lenalidomide maintenance over observation following autologous stem cell transplantation (ASCT) among 300 patients with MCL in Italy and Portugal.
In the study, investigators monitored MRD in both peripheral blood and bone marrow at 10 fixed time points throughout treatment (including induction, consolidation, post ASCT, and then every 6 months during maintenance and follow-up), yielding 4,351 individual MRD results.
Individual MRD analyses were prognostic in MCL, according to the investigators, with results that were relevant to disease progression right after ASCT, and were most predictive starting at 6 months after ASCT.
However, the best way to exploit the bulk of MRD information that had been collected, investigators said, was a model that combined regularly updated MRD results with MIPI scores.
This MIPI-adjusted model, based on MRD assessed in bone marrow by real-time quantitative polymerase chain reaction (RQ-PCR), outperformed both MIPI and a MIPI-adjusted single time-point analysis in terms of predicting time to progression.
The predictive power of the MIPI-adjusted bone marrow RQ-PCR analysis was illustrated by an area under the curve of 0.85-0.87, compared with an AUC of just 0.60-0.63 for classic MIPI analysis, 0.62-0.65 for MIPI-adjusted MRD at a post-ASCT time-point analysis, and 0.74-0.77 for MIPI-adjusted MRD at 6 months from transplant.
Peripheral blood ‘easier to collect’
Although bone marrow analysis performed best in the single-point MRD evaluations, looking at MRD over time greatly improved the predictive power of the peripheral blood MRD results, yielding an AUC up to 0.81, according to the report.
This enhancement of peripheral blood performance is a finding that may have important clinical implications, according to Dr. Ferrero, considering that peripheral blood monitoring is more practical for long-term, repeated MRD monitoring.
“It is interesting, because peripheral blood is easier to collect than bone marrow,” Dr. Ferrero said. “So if you plan in your analysis to monitor MRD in peripheral blood every 6 months, then you can have a predictive value similar to that of one single point in bone marrow.”
Dr. Ferrero provided disclosures related to Janssen, EUSA Pharma, Gilead, Morphosys, Incyte, Clinigen, Servier, and Gentili. The other authors reported no relevant conflicts of interest.

“It is interesting, because peripheral blood is easier to collect than bone marrow,” Dr. Ferrero said. “So if you plan in your analysis to monitor MRD in peripheral blood every 6 months, then you can have a predictive value similar to that of one single point in bone marrow.”
Dr. Ferrero provided disclosures related to Janssen, EUSA Pharma, Gilead, Morphosys, Incyte, Clinigen, Servier, and Gentili. The other authors reported no relevant conflicts of interest.

CDC warns of early uptick in respiratory disease
The Centers for Disease Control and Prevention is warning of an early surge in respiratory disease caused by multiple viruses. As influenza viruses, respiratory syncytial virus (RSV), SARS-CoV-2, and rhinovirus/enterovirus simultaneously circulate, the agency cautioned that this confluence of viral activity could strain the health care system, according to a CDC Health Network Alert advisory issued Nov. 4.
“This early increase in disease incidence highlights the importance of optimizing respiratory virus prevention and treatment measures, including prompt vaccination and antiviral treatment,” the alert stated.
The CDC reports that RSV activity is increasing nationally, but in some areas – such as the South and Mountain West – cases appear to be trending downward.
Influenza cases continue to climb, with the virus activity being the highest in the South, Mid-Atlantic, and the south-central West Coast, according to CDC data. “In fact, we’re seeing the highest influenza hospitalization rates going back a decade,” said José Romero, MD, director of the CDC’s National Center for Immunization and Respiratory Diseases, during a press briefing. The agency estimates that there have been 1.6 million illnesses, 13,000 hospitalizations, and 730 deaths from the flu so far this season. As of Nov. 4, there have been two pediatric deaths.
COVID-19 cases appear to have plateaued in the past three weeks, Dr. Romero said; however, the CDC expects that there will be “high-level circulation of SARS-CoV-2 this fall and winter,” the health alert stated.
The CDC advised that all eligible individuals aged 6-months or older should be vaccinated against COVID-19 and influenza. To protect against RSV-hospitalization, high-risk children should receive the monoclonal antibody drug palivizumab (Synagis). High-risk children include infants born before 29 weeks, children younger than age 2 with chronic lung disease or hemodynamically significant congenital heart disease, and children with suppressed immune systems or neuromuscular disorders.
Any patient with confirmed or suspected flu who is hospitalized, at higher risk for influenza complications, or who has a severe or progressive illness should be treated as early as possible with antivirals, such as oral oseltamivir (Tamiflu).
Patients with confirmed SARS-CoV-2 infection with increased risk of complications should also be treated with antivirals, such as nirmatrelvir and ritonavir (Paxlovid) or remdesivir (Veklury).
Patients should also be reminded to wash their hands frequently, cover coughs and sneezes, stay home when sick, and avoid close contact with people who are sick, the CDC advised.
“There’s no doubt that we will face some challenges this winter,” said Dawn O’Connell, HHS Assistant Secretary for Preparedness and Response, “but it’s important to remember that RSV and flu are not new, and we have safe and effective vaccines for COVID-19 and the flu.”

Dementia prevalence study reveals inequities
based on new U.S. data from The Health and Retirement Study (HRS).
These inequities likely stem from structural racism and income inequality, necessitating a multifaceted response at an institutional level, according to lead author Jennifer J. Manly, PhD, a professor of neuropsychology in neurology at the Gertrude H. Sergievsky Center and the Taub Institute for Research in Aging and Alzheimer’s Disease at Columbia University, New York.
A more representative dataset
Between 2001 and 2003, a subset of HRS participants underwent extensive neuropsychological assessment in the Aging, Demographics, and Memory Study (ADAMS), providing data which have since been cited by hundreds of published studies, the investigators wrote in JAMA Neurology. Those data, however, failed to accurately represent the U.S. population at the time, and have not been updated since.
“The ADAMS substudy was small, and the limited inclusion of Black, Hispanic, and American Indian or Alaska Native participants contributed to lack of precision of estimates among minoritized racial and ethnic groups that have been shown to experience a higher burden of cognitive impairment and dementia,” Dr. Manly and colleagues wrote.
The present analysis used a more representative dataset from HRS participants who were 65 years or older in 2016. From June 2016 to October 2017, 3,496 of these individuals underwent comprehensive neuropsychological test battery and informant interview, with dementia and MCI classified based on standard diagnostic criteria.
In total, 393 people were classified with dementia (10%), while 804 had MCI (22%), both of which approximate estimates reported by previous studies, according to the investigators. In further alignment with past research, age was a clear risk factor; each 5-year increment added 17% and 95% increased risk of MCI and dementia, respectively.
Compared with college-educated participants, individuals who did not graduate from high school had a 60% increased risk for both dementia (odds ratio, 1.6; 95% confidence interval, 1.1-2.3) and MCI (OR, 1.6; 95% CI, 1.2-2.2). Other educational strata were not associated with significant differences in risk.
Compared with White participants, Black individuals had an 80% increased risk of dementia (OR, 1.8; 95% CI, 1.2-2.7), but no increased risk of MCI. Conversely, non-White Hispanic individuals had a 40% increased risk of MCI (OR, 1.4; 95% CI, 1.0-2.0), but no increased risk of dementia, compared with White participants.
“Older adults racialized as Black and Hispanic are more likely to develop cognitive impairment and dementia because of historical and current structural racism and income inequality that restrict access to brain-health benefits and increase exposure to harm,” Dr. Manly said in a written comment.
These inequities deserve a comprehensive response, she added.
“Actions and policies that decrease discriminatory and aggressive policing policies, invest in schools that serve children that are racialized as Black and Hispanic, repair housing and economic inequalities, and provide equitable access to mental and physical health, can help to narrow disparities in later life cognitive impairment,” Dr. Manly said. “Two other areas of focus for policy makers are the shortage in the workforce of dementia care specialists, and paid family leave for caregiving.”
Acknowledging the needs of the historically underrepresented
Lealani Mae Acosta, MD, MPH, associate professor of neurology at Vanderbilt University Medical Center, Nashville, Tenn., applauded the investigators for their “conscious effort to expand representation of historically underrepresented minorities.”
The findings themselves support what has been previously reported, Dr. Acosta said in an interview, including the disproportionate burden of cognitive disorders among people of color and those with less education.
Clinicians need to recognize that certain patient groups face increased risks of cognitive disorders, and should be screened accordingly, Dr. Acosta said, noting that all aging patients should undergo such screening. The push for screening should also occur on a community level, along with efforts to build trust between at-risk populations and health care providers.
While Dr. Acosta reiterated the importance of these new data from Black and Hispanic individuals, she noted that gaps in representation remain, and methods of characterizing populations deserve refinement.
“I’m a little bit biased because I’m an Asian physician,” Dr. Acosta said. “As much as I’m glad that they’re highlighting these different disparities, there weren’t enough [participants in] specific subgroups like American Indian or Alaska Native, Asian, Native Hawaiian or Pacific Islander, to be able to identify specific trends within [those groups] that are, again, historically underrepresented patient populations.”
Grouping all people of Asian descent may also be an oversimplification, she added, as differences may exist between individuals originating from different countries.
“We always have to be careful about lumping certain groups together in analyses,” Dr. Acosta said. “That’s just another reminder to us – as clinicians, as researchers – that we need to do better by our patients by expanding research opportunities, and really studying these historically underrepresented populations.”
The study was supported by the National Institute on Aging. The investigators disclosed additional relationships with the Alzheimer’s Association and the National Institutes of Health. Dr. Acosta reported no relevant competing interests.

Viagra, Cialis, and Alzheimer’s risk: New data
The findings contradict results from a previous study that suggested that individuals who take sildenafil (Viagra) were significantly less likely to develop Alzheimer’s.
The new research, part of a larger effort to identify existing medications that could be repurposed to treat ADRD, employed a study design that reduced the risk for potential bias that may have influenced the earlier findings, the investigators note.
“That study came out last fall and was widely covered in the media, and we thought there were some methodological shortcomings that might have explained the results,” lead investigator Rishi Desai, PhD, assistant professor of medicine at Harvard Medical School and an associate epidemiologist at Brigham and Women’s Hospital, both in Boston, said in an interview.
The new study was published online in Brain Communications.
Not the final word?
Animal studies suggest that phosphodiesterase-5 (PDE5) inhibitors, a drug class that includes the ED drugs sildenafil and tadalafil (Cialis), improve memory and cognitive function and reduce amyloid burden. But studies in humans have yielded conflicting results.*
Although the new research and the work published last year both drew on Medicare data, they examined different patient populations.
The first study compared those who took sildenafil for any reason to those who did not take it. That design likely resulted in an analysis of a comparison of individuals with ED – the most common indication for sildenafil – to generally older individuals with diabetes or hypertension, Dr. Desai said.
In contrast, the current study included only those with pulmonary arterial hypertension (PAH), which is also an indication for PDE5 inhibitors. The researchers compared ADRD incidence in those who took PDE5 inhibitors with the incidence among those who took a different medication to treat their PAH. They used propensity matching to create two groups with similar characteristics and examined the data using four analytic strategies.
The investigators found no significant difference between groups in the incidence of ADRD, regardless of the strategy they used. Cell culture studies also revealed no protective effect from PDE5 inhibitors.
“No study of this kind should claim the final word,” Dr. Desai said. “It is extremely difficult to nail down causality from these types of data sources.”
Impressive study design
Commenting on the findings, David Knopman, MD, professor of neurology at Mayo Clinic, Rochester, Minn., described the study design as “impressive” for its efforts to minimize bias, a key limitation in the previous study.
“It was always the case that the claims about sildenafil needed further developmental work prior to testing the drug in randomized controlled trials,” Dr. Knopman said. “The evidence for the use of the drug was never sufficient for clinicians to use it in their patients.”
The study was funded by National Institute on Aging. Dr. Desai is an investigator who receives research grants from Bayer, Vertex, and Novartis that were given to the Brigham and Women’s Hospital for unrelated projects. Dr. Knopman has disclosed no relevant financial relationships.

Has the pandemic affected babies’ brain development?
There’s some good overall news in a large analysis that looked at whether a mother’s COVID-19 infection or birth during the pandemic could affect a baby’s brain development.
Researchers studied 21,419 infants who had neurodevelopmental screening during the pandemic (from January 2020 to January 2021) and compared them with babies born before the pandemic (2015-2019).
They found in an analysis of eight studies that, generally, brain development in infants ages 6-12 months old was not changed by COVID-19.
Communication skill scores lower than prepandemic
However, one area did see a significant difference when they looked at answers to the Ages and Stages Questionnaire, 3rd edition (ASQ-3): Scores were lower in communication skills.
Compared with the prepandemic babies, the pandemic group of babies was more likely to have communication impairment (odds were 1.7 times higher).
Additionally, mothers’ SARS-CoV-2 infection was not associated with significant differences in any neurodevelopment sector in offspring, with one exception: Odds were 3.5 times higher for fine motor impairment in the pandemic baby group.
The babies in this study were either exposed in the womb to the SARS-CoV-2 infection or screened during the pandemic regardless of whether they were exposed to the virus.
The study, led by Kamran Hessami, MD, with the Maternal Fetal Care Center at Boston Children’s Hospital and Harvard Medical School in Boston, was published in JAMA Network Open.
Potential reasons for lower communication skills
The study points to some factors of the pandemic that may be tied to impaired communication skills.
“Higher levels of COVID-19–related stress were reported for both mothers and fathers of infants aged 0-6 months and were associated with insensitive parenting practices, including decreased emotional responsiveness in only mothers, which could lessen the reciprocal exchanges that support language development in early childhood,” they write. “Additionally, opportunities to promote language and social development through new experiences outside the home, including visits with extended family and friends or attendance at a child care center, were lessened for many during the pandemic.”
Viviana M. Fajardo Martinez, MD, with neonatal/perinatal medicine at University of California, Los Angeles, Health, told this publication her team is also studying child development before and after the pandemic over a 3-year period, and delayed communication skills is something she is seeing in clinic there.
She says some parents have been concerned, saying their babies aren’t talking enough or are behind in vocabulary.
Babies can catch up after 12 months
One thing she tells parents is that babies who are a bit delayed at 12 months can catch up.
Up to 18 months, they can catch up, she said, adding that they can be reevaluated then for improvement. If, at that point, the baby is not catching up, “that’s when we refer for early intervention,” she said.
Dr. Martinez also tells parents concerned about their infant’s communication skills that it’s important to talk, read, and sing to their child. She said amid pandemic stress, corners may have been cut in asking children to use language skills.
For instance, if a child points to an apple, a stressed parent may just give the child the apple instead of asking the child to request it by name and repeat the word several times.
She also said a limitation of this study is the use of the ASQ-3 questionnaire, which is filled out by parents. Answers are subjective, she notes, and sometimes differ between one child’s two parents. The questionnaire was commonly used during the pandemic because a more objective, professional evaluation has been more difficult.
However, a measure like the Bayley Scales of Infant and Toddler Development Screening Test adds objectivity and will likely give a better picture as research progresses, Dr. Martinez said.

Andréane Lavallée, PhD, and Dani Dumitriu, MD, PhD, both with the department of pediatrics at Columbia University, New York, write in an invited commentary that the overall positive message of the study “should not make researchers complacent” and results should be viewed with caution.
They point out that the precise effects of this novel virus are still unclear and the age group and variables studied may not tell the whole story.
“It should be noted that this systematic review did not consider timing of exposure during pregnancy, maternal infection severity, or exposure to various SARS-CoV-2 variants – all factors that could eventually be proven to contribute to subtle adverse neurodevelopmental outcomes,” they write.
Additionally, past pandemics “such as the 1918 Spanish flu, 1964 rubella, and 2009 H1N1” have taught researchers to watch for increases in diagnoses such as autism spectrum disorder (ASD) and schizophrenia in subsequent years.
“ASD is generally diagnosed at age 3-5 years (and often not until early teens), while schizophrenia is generally diagnosed in mid-to-late 20s,” the editorialists point out. The authors agree and emphasize the need for long-term studies.

There’s some good overall news in a large analysis that looked at whether a mother’s COVID-19 infection or birth during the pandemic could affect a baby’s brain development.
Researchers studied 21,419 infants who had neurodevelopmental screening during the pandemic (from January 2020 to January 2021) and compared them with babies born before the pandemic (2015-2019).
They found in an analysis of eight studies that, generally, brain development in infants ages 6-12 months old was not changed by COVID-19.
Communication skill scores lower than prepandemic
However, one area did see a significant difference when they looked at answers to the Ages and Stages Questionnaire, 3rd edition (ASQ-3): Scores were lower in communication skills.
Compared with the prepandemic babies, the pandemic group of babies was more likely to have communication impairment (odds were 1.7 times higher).
Additionally, mothers’ SARS-CoV-2 infection was not associated with significant differences in any neurodevelopment sector in offspring, with one exception: Odds were 3.5 times higher for fine motor impairment in the pandemic baby group.
The babies in this study were either exposed in the womb to the SARS-CoV-2 infection or screened during the pandemic regardless of whether they were exposed to the virus.
The study, led by Kamran Hessami, MD, with the Maternal Fetal Care Center at Boston Children’s Hospital and Harvard Medical School in Boston, was published in JAMA Network Open.

Finerenone: ‘Striking’ cut in pneumonia, COVID-19 risks
The nonsteroidal mineralocorticoid receptor antagonist finerenone (Kerendia) unexpectedly showed that it might protect against incident infective pneumonia and COVID-19. The finding was based on secondary analyses run on more than 13,000 people enrolled in the two pivotal trials for finerenone.
Finerenone was approved by the Food and Drug Administration in 2021 for slowing progressive renal dysfunction and preventing cardiovascular events in adults with type 2 diabetes and chronic kidney disease (CKD).
‘Striking reduction in the risk of pneumonia’
The “striking reduction in risk of pneumonia” in a new analysis suggests that “the propagation of pulmonary infection into lobar or bronchial consolidation may be reduced by finerenone,” write Bertram Pitt, MD, and coauthors in a report published on October 26 in JAMA Network Open.
They also suggest that if further studies confirm that finerenone treatment reduces complications from pneumonia and COVID-19, it would have “significant medical implications,” especially because of the limited treatment options now available for complications from COVID-19.
The new analyses used the FIDELITY dataset, a prespecified merging of results from the FIDELIO-DKD and FIGARO-DKD trials, which together enrolled 13,026 people with type 2 diabetes and CKD, as determined on the basis of the patients’ having a urine albumin-to-creatinine ratio of at least 30 mg/g.
The primary outcomes of these trials showed that treatment with finerenone led to significant slowing of the progression of CKD and a significant reduction in the incidence of cardiovascular events, compared with placebo during median follow-up of 3 years.
The new, secondary analyses focused on the 6.0% of participants in whom there was evidence of pneumonia and the 1.6% in whom there was evidence of having COVID-19. Pneumonia was the most common serious adverse event in the two trials, a finding consistent with the documented risk for pneumonia faced by people with CKD.
Finerenone linked with a 29% relative reduction in pneumonia
When analyzed by treatment, the incidence of pneumonia was 4.7% among those who received finerenone and 6.7% among those who received placebo. This translated into a significant relative risk reduction of 29% associated with finerenone treatment.
Analysis of COVID-19 adverse events showed a 1.3% incidence among those who received finerenone and a 1.8% incidence among those in the placebo group, which translated into a significant 27% relative risk reduction linked with finerenone treatment.
In contrast, the data showed no reduced incidence of several other respiratory infections among the finerenone recipients, including nasopharyngitis, bronchitis, and influenza. The data also showed no signal that pneumonia or COVID-19 was more severe among the people who did not receive finerenone, nor did finerenone treatment appear to affect pneumonia recovery.
Analysis based on adverse events reports
These secondary analyses are far from definitive. The authors relied on pneumonia and COVID-19 being reported as adverse events. Each investigator diagnosed pneumonia at their discretion, and the trials did not specify diagnostic criteria. The authors also acknowledge that testing for COVID-19 was “not widespread” and that one of the two pivotal trials largely ran prior to the onset of the COVID-19 pandemic so that only 6 participants developed COVID-19 symptoms out of more than 5,700 enrolled.
The authors hypothesize that several actions of finerenone might potentially help mediate an effect on pneumonia and COVID-19: improvements in pulmonary inflammation and fibrosis, upregulation of expression of angiotensin converting enzyme 2, and amelioration of right heart pressure and pulmonary congestion. Also, antagonizing the mineralocorticoid receptor on monocytes and macrophages may block macrophage infiltration and accumulation of active macrophages, which can mediate the pulmonary tissue damage caused by COVID-19.
The FIDELIO-DKD and FIGARO-DKD trials and the FIDELITY combined database were sponsored by Bayer, the company that markets finerenone (Kerendia). Dr. Pitt has received personal fees from Bayer and personal fees and stock options from numerous other companies. Several coauthors reported having a financial relationship with Bayer, as well as with other companies.

A special part of the brain lights up when we see food
“We eat first with our eyes.”
The Roman foodie Apicius is thought to have uttered those words in the 1st century A.D. Now, some 2,000 years later, scientists may be proving him right.
Dubbed the “ventral food component,” this part resides in the brain’s visual cortex, in a region known to play a role in identifying faces, scenes, and words.
The study, published in the journal Current Biology, involved using artificial intelligence (AI) technology to build a computer model of this part of the brain. Similar models are emerging across fields of research to simulate and study complex systems of the body. A computer model of the digestive system was recently used to determine the best body position for taking a pill.
“The research is still cutting-edge,” says study author Meenakshi Khosla, PhD. “There’s a lot more to be done to understand whether this region is the same or different in different individuals, and how it is modulated by experience or familiarity with different kinds of foods.”
Pinpointing those differences could provide insights into how people choose what they eat, or even help us learn what drives eating disorders, Dr. Khosla says.
Part of what makes this study unique was the researchers’ approach, dubbed “hypothesis neutral.” Instead of setting out to prove or disprove a firm hypothesis, they simply started exploring the data to see what they could find. The goal: To go beyond “the idiosyncratic hypotheses scientists have already thought to test,” the paper says. So, they began sifting through a public database called the Natural Scenes Dataset, an inventory of brain scans from eight volunteers viewing 56,720 images.
As expected, the software analyzing the dataset spotted brain regions already known to be triggered by images of faces, bodies, words, and scenes. But to the researchers’ surprise, the analysis also revealed a previously unknown part of the brain that seemed to be responding to images of food.
“Our first reaction was, ‘That’s cute and all, but it can’t possibly be true,’ ” Dr. Khosla says.
To confirm their discovery, the researchers used the data to train a computer model of this part of the brain, a process that takes less than an hour. Then they fed the model more than 1.2 million new images.
Sure enough, the model lit up in response to food. Color didn’t matter – even black-and-white food images triggered it, though not as strongly as color ones. And the model could tell the difference between food and objects that looked like food: a banana versus a crescent moon, or a blueberry muffin versus a puppy with a muffin-like face.
From the human data, the researchers found that some people responded slightly more to processed foods like pizza than unprocessed foods like apples. They hope to explore how other things, such as liking or disliking a food, may affect a person’s response to that food.
This technology could open up other areas of research as well. Dr. Khosla hopes to use it to explore how the brain responds to social cues like body language and facial expressions.
For now, Dr. Khosla has already begun to verify the computer model in real people by scanning the brains of a new set of volunteers. “We collected pilot data in a few subjects recently and were able to localize this component,” she says.

Part of what makes this study unique was the researchers’ approach, dubbed “hypothesis neutral.” Instead of setting out to prove or disprove a firm hypothesis, they simply started exploring the data to see what they could find. The goal: To go beyond “the idiosyncratic hypotheses scientists have already thought to test,” the paper says. So, they began sifting through a public database called the Natural Scenes Dataset, an inventory of brain scans from eight volunteers viewing 56,720 images.
As expected, the software analyzing the dataset spotted brain regions already known to be triggered by images of faces, bodies, words, and scenes. But to the researchers’ surprise, the analysis also revealed a previously unknown part of the brain that seemed to be responding to images of food.
“Our first reaction was, ‘That’s cute and all, but it can’t possibly be true,’ ” Dr. Khosla says.
To confirm their discovery, the researchers used the data to train a computer model of this part of the brain, a process that takes less than an hour. Then they fed the model more than 1.2 million new images.
Sure enough, the model lit up in response to food. Color didn’t matter – even black-and-white food images triggered it, though not as strongly as color ones. And the model could tell the difference between food and objects that looked like food: a banana versus a crescent moon, or a blueberry muffin versus a puppy with a muffin-like face.
From the human data, the researchers found that some people responded slightly more to processed foods like pizza than unprocessed foods like apples. They hope to explore how other things, such as liking or disliking a food, may affect a person’s response to that food.
This technology could open up other areas of research as well. Dr. Khosla hopes to use it to explore how the brain responds to social cues like body language and facial expressions.
For now, Dr. Khosla has already begun to verify the computer model in real people by scanning the brains of a new set of volunteers. “We collected pilot data in a few subjects recently and were able to localize this component,” she says.

Tips on Better Patients Communication
SAN DIEGO—Don’t stand when you talk at bedside. Ditch the white gowns, turn away from your computers and pagers, and stop yourself from interrupting all the time.
These tips—and more—can help clinicians provide better and more effective care, said a colorectal surgeon who spoke about communication skills at the annual meeting of the Association of VA Hematology/Oncology (AVAHO).
Research has suggested that nearly half of Americans don’t think their health care practitioners (HCPs) are compassionate, “and that’s really sad,” said Lorene Valdez-Boyle, MD, MS, surgery chief at the New Mexico VA Health Care Service.
To combat this perception, she said, HCPs can adopt multiple strategies as they work with veterans and their families. The goal, she said, is “to try to get them to trust you and want to be part of their treatment. This is how we're going to have better outcomes.”
Some strategies are simple. Dr. Valdez-Boyle, for example, doesn’t wear a white gown when she sees patients. “Obviously, they’re really gross,” she said. “But also, I want them to be comfortable with me. I sit down at their level, and we have a conversation. We talk about our dogs and we bond, because that’s going to help them trust me and want to work with me. I do that with families too. We joke, and we laugh.”
Sitting bedside instead of standing is important, she said, and a 2016 study backs up this idea. “It’s difficult when you’re running around or you want to get to the next one, and the patient just keeps talking,” she said. But research showed that “when the clinician sat, the patient felt like they listened more carefully, and they explained things in a better way that was much easier for them to understand. They definitely had an improved perception of their [clinician’s] communication skills.”
She highlighted another 2016 study that examined a Commit to Sit initiative in which nurses were urged to sit with patients during each shift. Nurse communication scores and overall patient experience scores went up.
The VA now has a Commit to Sit initiative, which urges clinicians to put away computers, smart phones, and pagers. “The patient feels that we’ve listened more intently to their concerns and care more about them as a patient,” Dr. Valdez-Boyle said. “We have an improved understanding of their health as a result of this. It allows the site employee to continue to be efficient while still delivering compassionate care and fosters trusted relationships in an empathetic and respectful manner.”
For more about the initiative, visit the VA PX SharePoint.
The VA, she said, also has a Take a Moment initiative that emphasizes eye contact, face-to-face interaction without electronics for at least the first 5 minutes of each visit, and seated conversations.
Dr. Valdez-Boyle also urged colleagues to pay attention to how often they interrupt. She pointed to a 2019 study that reported that patients had a median of 11 seconds—yes, seconds—to explain their problem in two-thirds of clinician encounters. “I think some of it is because we think we know what they're going to say.”
In the age of COVID-19, she suggested turning to fist or elbow bumps instead of handshakes. And she said, let patients wear street clothes when appropriate so they’re more comfortable.
In the big picture, she said, good communication and a commitment to shared decision making “really create a shared responsibility. They give your patients ownership over their disease and the ability to make the decisions with their team.
Dr. Valdez-Boyle reported no disclosures.

Stroke management: There’s an app for that
“In clinical practice, guideline-driven patient care is very important in improving diagnosis and outcomes, and apps provide a very practical and easy way to check available guidelines,” senior author Fabio Pilato, MD, a neurologist at Università Campus Bio-Medico, Rome, told this news organization.
The review was published in the Journal of Stroke.
Reviewing the literature
“My colleagues and I wanted to discover whether smartphone apps, besides just facilitating communication between doctors and their patients, could improve patient care,” said Dr. Pilato. “We wanted to see if there were any apps that could guide clinical decisions according to guidelines and whether there were some being used in acute stroke management,” he added.
The investigators reviewed 43 studies of stroke-related mobile phone apps that were designed for the clinical management of stroke between June 1, 2007, when the first iPhone was introduced, and Jan. 31, 2022.
The apps were classified into the following three groups, according to their purpose: primary prevention apps, acute stroke management apps, and postacute stroke apps.
Prevention and management
The investigators found one primary prevention app, the Stroke Riskometer, that was based on an algorithm derived from the Framingham Stroke Risk Score and was designed to educate patients about diet, physical activity, and the warning signs of stroke. However, their review failed to show that the app was beneficial, compared with standard cardiovascular risk reduction.
Apps appeared to aid acute stroke management, according to the researchers. Prehospital apps, such as iLAMA, Smartphone-Assisted Pre-Hospital Medical Information System, FAST-ED, Egyptian Stroke Network, Act Fast, and the Mayo Clinic Acute Stroke Evaluation app were found to speed up stroke recognition, activate emergency medical services for speedier transport to the hospital, and facilitate communication with in-hospital stroke teams. All these prehospital apps reduced door-to-needle time.
The JOIN app also was shown to significantly reduce door-to-needle time, compared with no app support, in several studies. JOIN consists of a chat, a DICOM viewer, and an encrypted two-way video system for video calls between practitioners, as well as a milestones time stamp to record every step from home to hospital transportation to therapy onset.
StopStroke, another app that focuses on instant communication among physicians and allows real-time sharing of clinical data of stroke patients, reduced door-to-image and door-to-needle time, compared with no app.
Act Fast, which uses a National Institutes of Health Stroke Scale (NIHSS) calculator, a thrombolysis checklist, and a toolbox to share images and notes among practitioners involved in the decision-making process, decreased door-to-needle time by 16 minutes, compared with no app.
In a study of medical residents, adherence to guidelines was higher in participants who used the Mayo Clinic Acute Stroke Evaluation app, compared with those who did not. Door-to-needle time also was reduced by 16 minutes in the app-assisted group, compared with controls.
Postacute stroke apps
The Rehabilitation Guardian app, consisting of a health reminder, consultation, health information, and patient diary, gives medical information and provides rehabilitation exercises. Patients can enter their clinical information, and the medical staff can access it and assist with the rehab process remotely.
As for apps for chronic management and secondary prevention, Dr. Pilato and colleagues found that the PRESTRO app, which combines motivational support for a healthy lifestyle and tells patients to take their medications and measure their blood pressure, successfully got patients to be more physically active, compared with those who did not use the app.
Another app for secondary prevention, the Korea University Health Monitoring System for Stroke (KUHMS2), reduced blood pressure and glucose levels in patients who used it, compared with those who did not.
Lose It, a weight loss app, is an electronic food journal that shows the values of the macronutrients of foods that the patient consumes, as well as a daily calorie count. The Engaging Everyday Activities app effectively reminds patients who have had transient ischemic attacks about daily activities that can reduce their risk for a recurrent attack.
Movies4Stroke features educational videos about first aid, rehabilitation, how to improve swallowing, and stroke risk factors.
AFib 2gether allows patients to enter their clinical data and calculates their annual stroke risk scores. The information is provided to a health care provider before the next visit to help the patient make an informed decision about anticoagulation therapy.
“We believe that the widespread use of smartphones and apps may improve patient care in every part of the world and in particular in those parts where updated guideline consultation is not readily available. However, in our study we found that apps to implement guidelines by a clinical decision support system are still lacking. Our hope is that these apps will increase in the future,” said Dr. Pilato.
No panacea
Commenting on this review for this article, Amy Guzik, MD, associate professor of neurology at Wake Forest University School of Medicine, Winston-Salem, N.C., said that all physicians are looking for opportunities to use technology, especially in stroke, to diagnose and treat patients in the best way they can.
“Figuring out ways to increase efficiency and get the word out to our patients is very important to us and is probably why there are so many apps out there,” said Dr. Guzik.
“There are some ways such apps could be particularly useful. One is in remote hospitals that might not have a neurologist. Helping with the diagnosis and determining what is a bad stroke that needs to go to a higher level of medical care, or whether it is something the local hospital could take care of, would be useful,” said Dr. Guzik.
“Also helping EMS figure out which hospital to go to, or once they are on their way, being able to talk to the neurologist or neurosurgeon or the emergency room doctor and make a plan before the patient gets here, so we can expedite care when the patient arrives, is where apps can be particularly useful,” she added.
There are limitations to what apps can do, however. In the case of stroke, patients may often have important barriers that do not allow them to use apps at all, she said.
“Regardless of how they are being taken care of, a lot of our stroke patients will have problems with technology. A stroke can make texting difficult. Patients may have language difficulties, weakness, or cognitive impairment. They are relying on caregivers. All of this makes it difficult for a tech solution to be the automatic solution, unless things are done in a thoughtful way to make sure that it is appropriate for stroke patients.
“Also, there are a lot of elderly patients who may not necessarily be the most tech savvy and do not have as much digital literacy as younger patients. Another limitation to consider is that some people may not even have easy access to technology. So we must make sure that this is all done with an equity focus,” said Dr. Guzik.
The study was funded by the Associazione Nazionale fra le Imprese Assicuratrici (ANIA). Dr. Pilato and Dr. Guzik reported no relevant financial relationships.
