Bronchitis the leader at putting children in the hospital
About 7% (99,000) of the 1.47 million nonmaternal, nonneonatal hospital stays in children aged 0-17 years involved a primary diagnosis of acute bronchitis in 2018, representing the leading cause of admissions in boys (154.7 stays per 100,000 population) and the second-leading diagnosis in girls (113.1 stays per 100,000), Kimberly W. McDermott, PhD, and Marc Roemer, MS, said in a statistical brief.
Depressive disorders were the most common primary diagnosis in girls, with a rate of 176.7 stays per 100,000, and the second-leading diagnosis overall, although the rate was less than half that (74.0 per 100,000) in boys. Two other respiratory conditions, asthma and pneumonia, were among the top five for both girls and boys, as was epilepsy, they reported.
The combined rate for all diagnoses was slightly higher for boys, 2,051 per 100,000, compared with 1,922 for girls, they said based on data from the National Inpatient Sample.
“Identifying the most frequent primary conditions for which patients are admitted to the hospital is important to the implementation and improvement of health care delivery, quality initiatives, and health policy,” said Dr. McDermott of IBM Watson Health and Mr. Roemer of the AHRQ.

Physicians wearing white coats rated more experienced
Physicians wearing white coats were rated as significantly more experienced and professional than peers wearing casual attire. Regardless of their attire, however, female physicians were more likely to be judged as appearing less professional and were more likely to be misidentified as medical technicians, physician assistants, or nurses, found research published in JAMA Network Open.
“A white coat with scrubs attire was most preferred for surgeons (mean preference index, 1.3), whereas a white coat with business attire was preferred for family physicians and dermatologists (mean preference indexes, 1.6 and 1.2, respectively; P < .001),” Helen Xun, MD, Johns Hopkins University, Baltimore, and colleagues wrote. “A male model wearing business inner wear with a white coat, fleece jacket, or softshell jacket was perceived as significantly more professional than a female model wearing the same attire (mean professionalism score: male, 65.8; female, 56.2; mean difference in professionalism score: white coat, 12.06; fleece, 7.89; softshell, 8.82; P < .001). ... A male model wearing hospital scrubs or fashion scrubs alone was also perceived as more professional than a female model in the same attire.”
While casual attire, such as fleece or softshell jackets emblazoned with the names of the institution and wearer, has become more popular attire for physicians in recent years, the researchers noted theirs is the first published research to identify associations between gender, attire, and how people distinguish between various health care roles. The study authors launched their web-based survey from May to June 2020 and asked people aged 18 years and older to rate a series of photographs of deidentified models wearing health care attire. Inner wear choices were business attire versus scrubs with and without outer wear options of a long white coat, gray fleece jacket, or black softshell jackets. Survey respondents ranked the images on a 6-point Likert scale with 1 being the least experienced, professional, and friendly and 6 being the most experienced, professional, and friendly. Survey respondents also viewed individual images of male or female models and were asked to rate their professionalism on a scale of 0-100 – with 100 as the “most professional” as well as to identify their profession as either physician, surgeon, nurse, medical technician, or physician assistant.
The study team included 487 (93.3%) of 522 completed surveys in their analyses. Respondents’ mean age was 36.2 years; 260 (53.4%) were female; 372 (76.4%) were White; 33 (6.8%) were Black or African American. Younger respondents and those living in the Western United States who had more exposure to physician casual attire appeared more accepting of it, the authors wrote.
“I remember attending my white-coat ceremony as a medical student, and the symbolism of it all representing me entering the profession. It felt very emotional and heavy and I felt very proud to be there. I also remember taking a ‘selfie’ in my long white coat as a doctor for the first time before my first shift as a resident. But, I’ve also been wearing that same white coat, and a large badge with a ‘DOCTOR’ label on it, and been mistaken by a patient or parent for something other than the physician,” Alexandra M. Sims, a pediatrician and health equity researcher in Cincinnati, said in an interview. “So, I’d really hope that the take-home here is not simply that we must wear our white coats to be considered more professional. I think we have to unpack and dismantle how we’ve even built this notion of ‘professionalism’ in the first place. Women, people of color, and other marginalized groups were certainly not a part of the defining, but we must be a part of the reimagining of an equitable health care profession in this new era.”
As sartorial trends usher in more casual attire, clinicians should redouble efforts to build rapport and enhance communication with patients, such as clarifying team members’ roles when introducing themselves. Dr. Xun and coauthors noted that addressing gender bias is important for all clinicians – not just women – and point to the need for institutional and organizational support for disciplines where gender bias is “especially prevalent,” like surgery. “This responsibility should not be undertaken only by the individuals that experience the biases, which may result in additional cumulative career disadvantages. The promotion of equality and diversity begins with recognition, characterization, and evidence-supported interventions and is a community operation,” Dr. Xun and colleagues concluded.
“I do not equate attire to professionalism or experience, nor is it connected to my satisfaction with the physician. For myself and my daughter, it is the experience of care that ultimately influences our perceptions regarding the professionalism of the physician,” Hala H. Durrah, MTA, parent to a chronically ill child with special health care needs and a Patient and Family Engagement Consultant, said in an interview. “My respect for a physician will ultimately be determined by how my daughter and I were treated, not just from a clinical perspective, but how we felt during those interactions.”

Surgeon marks ‘right’ instead of ‘left’ testicle, then operates
Wrong-site surgery
Florida regulators have imposed a fine and other measures on a Tampa doctor who made a crucial error prior to his patient’s testicular surgery, as a story in the Miami Herald, among other news sites, reports.
On Sept. 10, 2019, a patient referred to in state documents as “C.F.” showed up for a procedure – a varicocelectomy – that would remove the enlarged veins in his left testicle. His doctor that day was Raul Fernandez-Crespo, MD, a urologist who had been licensed to practice in Florida since April of the same year. Dr. Fernandez-Crespo completed his urology residency at the University of Puerto Rico in 2019.
Following a conversation with C.F., Dr. Fernandez-Crespo designated what he believed was the proper surgical site – his patient’s right testicle.
He then proceeded to operate, but at some point during the procedure – news accounts don’t make clear when or how he became aware of his error – he realized C.F. had actually consented to a left-testicle varicocelectomy. With his patient still sedated, Dr. Fernandez-Crespo also completed the second procedure.
His mistake came to the attention of the Department of Health, which filed an administrative complaint against the surgeon. On June 17, 2021, the department’s medical licensing body, the Florida Board of Medicine, handed down its final order about the case.
In addition to imposing a $2,500 fine on Dr. Fernandez-Crespo and issuing “a letter of concern” – a public document that can be used as evidence in any relevant future disciplinary action against him – regulators said the surgeon must reimburse $2,045.56 to the department for its case-related administrative costs; take a 5-hour CME course in risk management or attend 8 hours of board disciplinary hearings; and, finally, give a 1-hour lecture on wrong-site surgeries at a board-approved medical facility.
Before this, Dr. Fernandez-Crespo had no previous disciplinary history with the Florida Board of Medicine.
Huge judgment after fertility procedure goes wrong
A Connecticut couple whose fertility and prenatal care at a state university health center proved disastrous will receive millions of dollars in damages, according to a report in the Hartford Courant.
In 2014, Jean-Marie Monroe-Lynch and her husband, Aaron Lynch, went to UConn Health, in Farmington, for treatment of Jean-Marie’s infertility. Her care was overseen by the Center for Advanced Reproductive Services (CARS), a private company then under contract with UConn Health. (The contract, which ended in 2014, obligated UConn to provide CARS providers with medical malpractice coverage.)
There, Jean-Marie was inseminated with sperm from a donor who turned out to be a carrier for cytomegalovirus (CMV), the herpes virus that can cause severe birth defects, or fetal death, when contracted by a pregnant woman. The insemination resulted in a twin pregnancy, a boy and a girl. The girl, Shay, died in utero after several of her organs became infected with CMV; the boy, Joshua, was born with severe mental and physical disabilities.
In their suit, Ms. Monroe-Lynch and her husband alleged that they were never cautioned about the risks associated with using a sperm donor whose blood had tested positive for CMV antibodies. Their suit further alleged that, at the 20-week ultrasound, UConn’s prenatal team failed to detect evidence of congenital CMV infection and again failed, at the 22-week ultrasound, to properly recognize and respond to abnormal findings.
“They totally dropped the ball,” said the couple’s attorney. “If you’re a pregnant woman and contract the virus for the first time, the results can be devastating.”
CARS disputes this conclusion, arguing that the plaintiffs failed to prove as a “matter of scientific fact” that Ms. Monroe-Lynch was infected with CMV as the result of her intrauterine insemination.
But Superior Court Judge Mark H. Taylor disagreed. In his 107-page ruling, he said that the court “agrees with the vast majority of superior courts, concluding that a physician providing obstetric care owes a direct duty to a mother to prevent harm to her child during gestation and delivery.”
Jean-Marie Monroe-Lynch and Aaron Lynch received a $37.6 million award, consisting of $24.1 million in economic damages and $13.5 million in noneconomic damages.
Their surviving child, Joshua, will reportedly require a lifetime of medical and other care. In the meantime, UConn Health vows to appeal the Superior Court’s decision.
COVID patient’s relative demands justice for fatal outcome
An Indiana man whose grandfather recently died after suffering a stroke is calling on state lawmakers to rethink legislation passed earlier this year to protect health care providers during the COVID-19 pandemic, according to a story reported by CBS4Indy.
Late last year, Daniel Enlow’s 83-year-old grandfather, Edward Rigney, was checked into Eskenazi Hospital, in Indianapolis. Mr. Rigney suffered from COPD and had also been diagnosed with COVID-19.
At some point during his hospitalization, medical staff attempted to place what seems to have been an arterial line in order to monitor his condition. During the procedure, or at some point shortly thereafter, an “iatrogenic air embolus” was released into his veins and caused a stroke, according to medical records and Mr. Rigney’s death certificate.
“I started asking for medical records because I wanted to know what was happening leading up to it in black and white in front of me,” said Mr. Enlow, who wished to present his evidence to a medical review panel, as required by Indiana law. The first step in this process would have been to consult with a medical malpractice attorney, but several declined to take his case.
Why? Because a pair of bills passed by Indiana legislators in early 2021 make COVID-19–related suits – even tangentially related ones – potentially difficult to take to court.
The bills raised the bar to file a medical malpractice claim in COVID-19 cases and to allow only those that involve “gross negligence or willful or wanton misconduct.”
“In the vast majority of cases, it’s impossible to prove that,” said Fred Schultz, immediate past president of the Indiana Trial Lawyers Association, who lobbied against the legislation.
The bills were never designed to offer “blanket freedom,” said GOP State Senator Aaron Freeman, sponsor of one of the bills. “If something is being used in a way that it is a complete bar to certain claims, then maybe we need to go back and look at it and open that up a little bit and make it less restrictive. I’m certainly open to having those conversations.”
Meanwhile, Mr. Enlow has vowed to keep pushing in the name of his late grandfather. The hospital’s parent company, Eskenazi Health, has declined to comment.

In 2014, Jean-Marie Monroe-Lynch and her husband, Aaron Lynch, went to UConn Health, in Farmington, for treatment of Jean-Marie’s infertility. Her care was overseen by the Center for Advanced Reproductive Services (CARS), a private company then under contract with UConn Health. (The contract, which ended in 2014, obligated UConn to provide CARS providers with medical malpractice coverage.)
There, Jean-Marie was inseminated with sperm from a donor who turned out to be a carrier for cytomegalovirus (CMV), the herpes virus that can cause severe birth defects, or fetal death, when contracted by a pregnant woman. The insemination resulted in a twin pregnancy, a boy and a girl. The girl, Shay, died in utero after several of her organs became infected with CMV; the boy, Joshua, was born with severe mental and physical disabilities.
In their suit, Ms. Monroe-Lynch and her husband alleged that they were never cautioned about the risks associated with using a sperm donor whose blood had tested positive for CMV antibodies. Their suit further alleged that, at the 20-week ultrasound, UConn’s prenatal team failed to detect evidence of congenital CMV infection and again failed, at the 22-week ultrasound, to properly recognize and respond to abnormal findings.
“They totally dropped the ball,” said the couple’s attorney. “If you’re a pregnant woman and contract the virus for the first time, the results can be devastating.”
CARS disputes this conclusion, arguing that the plaintiffs failed to prove as a “matter of scientific fact” that Ms. Monroe-Lynch was infected with CMV as the result of her intrauterine insemination.
But Superior Court Judge Mark H. Taylor disagreed. In his 107-page ruling, he said that the court “agrees with the vast majority of superior courts, concluding that a physician providing obstetric care owes a direct duty to a mother to prevent harm to her child during gestation and delivery.”
Jean-Marie Monroe-Lynch and Aaron Lynch received a $37.6 million award, consisting of $24.1 million in economic damages and $13.5 million in noneconomic damages.
Their surviving child, Joshua, will reportedly require a lifetime of medical and other care. In the meantime, UConn Health vows to appeal the Superior Court’s decision.
COVID patient’s relative demands justice for fatal outcome
An Indiana man whose grandfather recently died after suffering a stroke is calling on state lawmakers to rethink legislation passed earlier this year to protect health care providers during the COVID-19 pandemic, according to a story reported by CBS4Indy.
Late last year, Daniel Enlow’s 83-year-old grandfather, Edward Rigney, was checked into Eskenazi Hospital, in Indianapolis. Mr. Rigney suffered from COPD and had also been diagnosed with COVID-19.
At some point during his hospitalization, medical staff attempted to place what seems to have been an arterial line in order to monitor his condition. During the procedure, or at some point shortly thereafter, an “iatrogenic air embolus” was released into his veins and caused a stroke, according to medical records and Mr. Rigney’s death certificate.
“I started asking for medical records because I wanted to know what was happening leading up to it in black and white in front of me,” said Mr. Enlow, who wished to present his evidence to a medical review panel, as required by Indiana law. The first step in this process would have been to consult with a medical malpractice attorney, but several declined to take his case.
Why? Because a pair of bills passed by Indiana legislators in early 2021 make COVID-19–related suits – even tangentially related ones – potentially difficult to take to court.
The bills raised the bar to file a medical malpractice claim in COVID-19 cases and to allow only those that involve “gross negligence or willful or wanton misconduct.”
“In the vast majority of cases, it’s impossible to prove that,” said Fred Schultz, immediate past president of the Indiana Trial Lawyers Association, who lobbied against the legislation.
The bills were never designed to offer “blanket freedom,” said GOP State Senator Aaron Freeman, sponsor of one of the bills. “If something is being used in a way that it is a complete bar to certain claims, then maybe we need to go back and look at it and open that up a little bit and make it less restrictive. I’m certainly open to having those conversations.”
Meanwhile, Mr. Enlow has vowed to keep pushing in the name of his late grandfather. The hospital’s parent company, Eskenazi Health, has declined to comment.

FDA’s fast-track approval process exposed as lax, in need of reform
an in-depth investigation published in The BMJ has determined.
“Despite the pathway’s good intentions to accelerate ‘the availability of drugs that treat serious diseases,’ experts are concerned that it is now being exploited – to the detriment of patients, who may be prescribed a drug that offers little benefit and possible harm, and to taxpayers,” writes Elisabeth Mahase, clinical reporter at The BMJ, who carried out the analysis.
The FDA’s accelerated approval pathway is intended to provide earlier access to drugs for serious diseases when there is lingering uncertainty at the time of approval regarding the drug’s ultimate clinical benefit.
Required studies rarely completed
As part of this fast-track pathway, drug manufacturers must conduct postapproval, phase 4 confirmatory trials to verify the anticipated clinical benefit. If these trials indicate no benefit, FDA approval can be withdrawn.
However, the analysis of FDA data shows once they are approved drugs are rarely taken off the market.
The BMJ investigation that analyzed data up to the end of 2020 shows that 112 of the 253 (44%) medications granted accelerated approval have not been confirmed to be effective.
In addition, 24 (21%) of these questionable drugs have been on the market for more than 5 years and some have been on the market for more than 20 years – often with a hefty price tag.
Furthermore, only 16 drugs approved through the accelerated approval process have ever been withdrawn, and most were shown to be ineffective, but in some cases the confirmatory trials were never done, Ms. Mahase reports.
For example, the COX-2 inhibitor celecoxib (Celebrex), which was granted accelerated approval in 1999 for the treatment of familial adenomatous polyposis, was on the market for 12 years before the FDA finally asked Pfizer to voluntarily withdraw it for this indication because efficacy trials were never completed.
As part of The BMJ’s investigation, Ms. Mahase asked manufacturers of the 24 drugs that have remained on the market for more than 5 years whether they had conducted the required phase 4 confirmatory trials. Six of the drugs had been withdrawn, approved, or postponed.
Of the remaining 18 drugs, the manufacturers provided the relevant trial information for only six. Only four drugmakers had started to recruit patients; two said they were still in discussion with the FDA over the final trial design.
“These products routinely have side effects, but the benefit information is a lot less certain. That’s what we’re concerned about – that we may have drugs on the market that don’t have any benefits, but certainly predictably have harms associated with them,” Huseyin Naci, PhD, MHS, with the London School of Economics, comments in the report.
Call for reform
As reported by this news organization, a 2015 report by the General Accountability Office (GAO) concluded that the FDA does not do an effective job of tracking the clinical efficacy or the safety of drugs with expedited approval after they hit the market.
In April of this year, the Institute for Clinical and Economic Review (ICER) cited a lack of “credible threats” to withdraw approval if companies don’t do confirmatory trials – meaning drugmakers have little incentive to do the trials.
“There are some instances where the companies really do seem to be taking advantage of the accelerated approval pathway and are using it in a way that makes it harder to get at the truth about whether these products really are safe and effective,” Rachel Sachs, JD, MPH, Washington University, St. Louis, said in The BMJ article.
In addition, the authors of a recent viewpoint article in JAMA Internal Medicine assert the recent approval of the controversial anti-amyloid drug aducanumab (Aduhelm, Biogen) shows that the accelerated approval pathway needs to be reformed.
Despite the concerns, Ms. Mahase said all experts who spoke to The BMJ believe the accelerated approval pathway is still useful and can be beneficial to patients, although some changes are needed.
One effective reform might be to have confirmatory trials designed, and even started, as part of accelerated approval.
“One important piece of the puzzle is for the FDA itself to be tougher on these companies, to hold them to the bargain that they have agreed to, and to take action when the company has not met their obligations,” Ms. Sachs told the journal.
An FDA spokesperson told the BMJ that the agency is “committed to working with sponsors to ensure that confirmatory studies are completed in a timely manner.”
“We expect sponsors to commit all resources needed to move trials forward as effectively as possible, with the aim of completing trials as soon as is feasible, while assuring the quality of the data and the robustness of the results,” the agency said.

‘A few mutations away’: The threat of a vaccine-proof variant
The Centers for Disease Control and Prevention Director Rochelle Walensky, MD, MPH, made a dire prediction during a media briefing this week that, if we weren’t already living within the reality of the COVID-19 pandemic, would sound more like a pitch for a movie about a dystopian future.
“For the amount of virus circulating in this country right now largely among unvaccinated people, the largest concern that we in public health and science are worried about is that the virus … [becomes] a very transmissible virus that has the potential to evade our vaccines in terms of how it protects us from severe disease and death,” Dr. Walensky told reporters on July 27.
A new, more elusive variant could be “just a few mutations away,” she said.
“That’s a very prescient comment,” Lewis Nelson, MD, professor and clinical chair of emergency medicine and chief of the division of medical toxicology at Rutgers New Jersey Medical School in Newark, told this news organization.
“We’ve gone through a few mutations already that have been named, and each one of them gets a little more transmissible,” he said. “That’s normal, natural selection and what you would expect to happen as viruses mutate from one strain to another.”
“What we’ve mostly seen this virus do is evolve to become more infectious,” said Stuart Ray, MD, when also asked to comment. “That is the remarkable feature of Delta – that it is so infectious.”
He said that the SARS-CoV-2 has evolved largely as expected, at least so far. “The potential for this virus to mutate has been something that has been a concern from early on.”
“The viral evolution is a bit like a ticking clock. The more we allow infections to occur, the more likely changes will occur. When we have lots of people infected, we give more chances to the virus to diversify and then adapt to selective pressures,” said Dr. Ray, vice-chair of medicine for data integrity and analytics and professor in the division of infectious diseases at Johns Hopkins School of Medicine in Baltimore.
Dr. Nelson said.
If this occurs, he added, “we will have an ineffective vaccine, essentially. And we’ll be back to where we were last March with a brand-new disease.”
Technology to the rescue?
The flexibility of mRNA vaccines is one potential solution. These vaccines could be more easily and quickly adapted to respond to a new, more vaccine-elusive variant.
“That’s absolutely reassuring,” Dr. Nelson said. For example, if a mutation changes the spike protein and vaccines no longer recognize it, a manufacturer could identify the new protein and incorporate that in a new mRNA vaccine.
“The problem is that some people are not taking the current vaccine,” he added. “I’m not sure what is going to make them take the next vaccine.”
Nothing appears certain
When asked how likely a new strain of SARS-CoV-2 could emerge that gets around vaccine protection, Dr. Nelson said, “I think [what] we’ve learned so far there is no way to predict anything” about this pandemic.
“The best way to prevent the virus from mutating is to prevent hosts, people, from getting sick with it,” he said. “That’s why it’s so important people should get immunized and wear masks.”
Both Dr. Nelson and Dr. Ray pointed out that it is in the best interest of the virus to evolve to be more transmissible and spread to more people. In contrast, a virus that causes people to get so sick that they isolate or die, thus halting transmission, works against viruses surviving evolutionarily.
Some viruses also mutate to become milder over time, but that has not been the case with SARS-CoV-2, Dr. Ray said.
Mutations not the only concern
Viruses have another mechanism that produces new strains, and it works even more quickly than mutations. Recombination, as it’s known, can occur when a person is infected with two different strains of the same virus. If the two versions enter the same cell, the viruses can swap genetic material and produce a third, altogether different strain.
Recombination has already been seen with influenza strains, where H and N genetic segments are swapped to yield H1N1, H1N2, and H3N2 versions of the flu, for example.
“In the early days of SARS-CoV-2 there was so little diversity that recombination did not matter,” Dr. Ray said. However, there are now distinct lineages of the virus circulating globally. If two of these lineages swap segments “this would make a very new viral sequence in one step without having to mutate to gain those differences.”
“The more diverse the strains that are circulating, the bigger a possibility this is,” Dr. Ray said.
Protected, for now
Dr. Walensky’s sober warning came at the same time the CDC released new guidance calling for the wearing of masks indoors in schools and in any location in the country where COVID-19 cases surpass 50 people per 100,000, also known as substantial or high transmission areas.
On a positive note, Dr. Walensky said: “Right now, fortunately, we are not there. The vaccines operate really well in protecting us from severe disease and death.”

COVID-19 leaves wake of medical debt among U.S. adults
Despite the passage of four major relief bills in 2020 and 2021 and federal efforts to offset pandemic- and job-related coverage loss, many people continued to face financial challenges, especially those with a low income and those who are Black or Latino.
The survey, which included responses from 5,450 adults, revealed that 10% of adults aged 19-64 were uninsured during the first half of 2021, a rate lower than what was recorded in 2020 and 2019 in both federal and private surveys. However, uninsured rates were highest among those with low income, those younger than 50 years old, and Black and Latino adults.
For most adults who lost employee health insurance, the coverage gap was relatively brief, with 54% saying their coverage gap lasted 3-4 months. Only 16% of adults said coverage gaps lasted a year or longer.
“The good news is that this survey is suggesting that the coverage losses during the pandemic may have been offset by federal efforts to help people get and maintain health insurance coverage,” lead author Sara Collins, PhD, Commonwealth Fund vice president for health care coverage, access, and tracking, said in an interview.
“The bad news is that a third of Americans continue to struggle with medical bills and medical debt, even among those who have health insurance coverage,” Dr. Collins added.
Indeed, the survey found that about one-third of insured adults reported a medical bill problem or that they were paying off medical debt, as did approximately half of those who were uninsured. Medical debt caused 35% of respondents to use up most or all of their savings to pay it off.
Meanwhile, 27% of adults said medical bills left them unable to pay for necessities such as food, heat, or rent. What surprised Dr. Collins was that 43% of adults said they received a lower credit rating as a result of their medical debt, and 35% said they had taken on more credit card debt to pay off these bills.
“The fact that it’s bleeding over into people’s financial security in terms of their credit scores, I think is something that really needs to be looked at by policymakers,” Dr. Collins said.
When analyzed by race/ethnicity, the researchers found that 55% of Black adults and 44% of Latino/Hispanic adults reported medical bills and debt problems, compared with 32% of White adults. In addition, 47% of those living below the poverty line also reported problems with medical bills.
According to the survey, 45% of respondents were directly affected by the pandemic in at least one of three ways – testing positive or getting sick from COVID-19, losing income, or losing employer coverage – with Black and Latinx adults and those with lower incomes at greater risk.
George Abraham, MD, president of the American College of Physicians, said the Commonwealth Fund’s findings were not surprising because it has always been known that underrepresented populations struggle for access to care because of socioeconomic factors. He said these populations were more vulnerable in terms of more severe infections and disease burden during the pandemic.
“[This study] validates what primary care physicians have been saying all along in regard to our patients’ access to care and their ability to cover health care costs,” said Dr. Abraham, who was not involved with the study. “This will hopefully be an eye-opener and wake-up call that reiterates that we still do not have equitable access to care and vulnerable populations are disproportionately affected.”
He believes that, although people are insured, many of them may contend with medical debt when they fall ill because they can’t afford the premiums.
“Even though they may have been registered for health coverage, they may not have active coverage at the time of illness simply because they weren’t able to make their last premium payments because they’ve been down, because they lost their job, or whatever else,” Dr. Abraham explained. “On paper, they appear to have health care coverage. But in reality, clearly, that coverage does not match their needs or it’s not affordable.”
For Dr. Abraham, the study emphasizes the need to continue support for health care reform, including pricing it so that insurance is available for those with fewer socioeconomic resources.
Yalda Jabbarpour, MD, medical director of the Robert Graham Center for Policy Studies, Washington, said high-deductible health plans need to be “reined in” because they can lead to greater debt, particularly among vulnerable populations.
“Hopefully this will encourage policymakers to look more closely at the problem of medical debt as a contributing factor to financial instability,” Dr. Jabbarpour said. “Federal relief is important, so is expanding access to comprehensive, affordable health care coverage.”
Dr. Collins said there should also be a way to raise awareness of the health care marketplace and coverage options so that people have an easier time getting insured.

Despite the passage of four major relief bills in 2020 and 2021 and federal efforts to offset pandemic- and job-related coverage loss, many people continued to face financial challenges, especially those with a low income and those who are Black or Latino.
The survey, which included responses from 5,450 adults, revealed that 10% of adults aged 19-64 were uninsured during the first half of 2021, a rate lower than what was recorded in 2020 and 2019 in both federal and private surveys. However, uninsured rates were highest among those with low income, those younger than 50 years old, and Black and Latino adults.
For most adults who lost employee health insurance, the coverage gap was relatively brief, with 54% saying their coverage gap lasted 3-4 months. Only 16% of adults said coverage gaps lasted a year or longer.
“The good news is that this survey is suggesting that the coverage losses during the pandemic may have been offset by federal efforts to help people get and maintain health insurance coverage,” lead author Sara Collins, PhD, Commonwealth Fund vice president for health care coverage, access, and tracking, said in an interview.
“The bad news is that a third of Americans continue to struggle with medical bills and medical debt, even among those who have health insurance coverage,” Dr. Collins added.
Indeed, the survey found that about one-third of insured adults reported a medical bill problem or that they were paying off medical debt, as did approximately half of those who were uninsured. Medical debt caused 35% of respondents to use up most or all of their savings to pay it off.
Meanwhile, 27% of adults said medical bills left them unable to pay for necessities such as food, heat, or rent.

Vaccinated people infected with Delta remain contagious
reported late on July 29.
, The New York TimesThe revelation is one reason the agency reversed course this week and said fully vaccinated people should go back to wearing masks in many cases.
The new findings also are a reversal from what scientists had believed to be true about other variants of the virus, the Times said. The bottom line is that the CDC data show people with so-called breakthrough cases of the Delta variant may be just as contagious as unvaccinated people, even if they do not show symptoms.
ABC News reported earlier on July 29 that the CDC’s updated mask guidance followed an outbreak in Cape Cod, where crowds gathered for the Fourth of July.
As of July 29, 882 people were tied to the outbreak centered in Provincetown, Mass. Of those who live in Massachusetts, 74% were unvaccinated. ABC said the majority were showing symptoms of COVID-19.

As common respiratory viruses resurface, children are at serious risk
Younger children may be vulnerable to the reemergence of common respiratory viruses such as influenza and respiratory syncytial virus (RSV) as COVID-19 restrictions wane, experts say. The impact could be detrimental.
The COVID-19 pandemic and the implementation of preventative measures such as social distancing, travel restrictions, mask use, and shelter in place, reduced the transmission of respiratory viruses, according to the Centers for Disease Control and Prevention. However, because older infants and toddlers have not been exposed to these bugs during the pandemic, they are vulnerable to suffering severe viral infections.
“[We’ve] been in the honeymoon for 18 months,” said Christopher J. Harrison, MD, professor of pediatrics and pediatric infectious diseases at Children’s Mercy Hospitals and Clinics in Kansas City, Mo. “We are going to be coming out of the honeymoon and the children who didn’t get sick are going to start packing 2 years’ worth of infections into the next 9 months so there’s going to be twice as many as would be normal.”
The CDC issued a health advisory in June for parts of the southern United States, such as Texas, the Carolinas, and Oklahoma, encouraging broader testing for RSV – a virus that usually causes mild, cold-like symptoms and is the most common cause of bronchiolitis and pneumonia in children – among those who test negative for COVID-19. Virtually all children get an RSV infection by the time they are 2 years old, according to the CDC.
In previous years, RSV usually spread during the fall and spring seasons and usually peaked late December to mid-February. However, there’s been an offseason spike in the common illness this year, with nearly 2,000 confirmed cases each week of July.
Richard J. Webby, PhD, of the infectious diseases department at St. Jude Children’s Research Hospital, Memphis, Tenn., said that although RSV transmits more easily during the winter, the virus is able to thrive during this summer because many children have limited immunity and are more vulnerable to catching the virus than before. Population immunity normally limits a virus to circulating under its most favorable conditions, which is usually the winter. However, because there are a few more “susceptible hosts,” it gives the virus the ability to spread during a time when it typically wouldn’t be able to.
“Now we have a wider range of susceptible kids because they haven’t had that exposure over the past 18 months,” said Dr. Webby, who is on the World Health Organization’s Influenza Vaccine Composition Advisory Team. “It gives the virus more chances to transmit during conditions that are less favorable.”
Dr. Harrison said that, if children continue to take preventative measures such as wearing masks and sanitizing, they can delay catching the RSV – which can be severe in infants and young children – until they’re older and symptoms won’t be as severe.
“The swelling that these viruses cause in the trachea and the bronchial tubes is much bigger in proportion to the overall size of the tubes, so it takes less swelling to clog up the trachea or bronchial tube for the 9-month-old than it does of a 9-year-old,” Dr. Harrison said. “So if a 9-year-old was to get RSV, they’re not going to have nearly the same amount symptoms as the 9-month-old.
Dr. Harrison said delaying RSV in children was never an option before because it’s a virus that’s almost impossible to avoid.
“Hopefully, the mask means that if you get exposed, instead of getting a million virus particles from your classmate or your playmate, you may only get a couple thousand,” Dr. Harrison explained. “And maybe that’s enough that you can fight it off or it may be small enough that you get a mild infection instead of a severe infection.”
A summer surge of RSV has also occurred in Australia. A study published in Clinical Infectious Diseases found that Western Australia saw a 98% reduction in RSV cases. This suggests that COVID-19 restrictions also delayed the RSV season.
Dr. Webby said the lax in penetrative measures against COVID-19 may also affect this upcoming flu season. Usually, around 10%-30% of the population gets infected with the flu each year, but that hasn’t happened the past couple of seasons, he said.
“There might be slightly less overall immunity to these viruses,” Dr. Webby said. “When these viruses do come back, there’s a little bit more room for them to take off.”
Although a severe influenza season rebound this winter is a possibility, Australia continues to experience a historically low flu season. Dr. Harrison, who said the northern hemisphere looks at what’s happening in Australia and the rest of the “southern half of the world because their influenza season is during our summer,” hopes this is an indication that the northern hemisphere will also experience a mild season.
However, there’s no indication of how this upcoming flu season will hit the United States and there isn’t any guidance on what could happen because these historically low levels of respiratory viruses have never happened before, Dr. Webby explained.
He said that, if COVID-19’s delta variant continues to circulate during the fall and winter seasons, it will keep other viruses at low levels. This is because there is rarely a peak of activity of different viruses at the same time.
“When you get infected with the virus, your body’s immune response has this nonspecific reaction that protects you from anything else for a short period of time,” Dr. Webby explained. “When you get a lot of one virus circulating, it’s really hard for these other viruses to get into that population and sort of set off an epidemic of their own.”
To prepare for an unsure influenza season, Dr. Harrison suggests making the influenza vaccine available in August as opposed to October.
Dr. Harrison and Dr. Webby reported no conflicts of interest.

Pfizer vaccine protection wanes after 6 months, study finds
, according to a new study.
The July 28 preprint report of the study, which has not been peer reviewed, suggests a gradual “declining trend in vaccine efficacy” over 6 months after two doses of the Pfizer vaccine in more than 45,000 people worldwide.
The study finds overall effectiveness falls from 96% to 84%.
At the same time, a third booster dose of the Pfizer vaccine increases neutralizing antibody levels against the Delta variant by more than five times, compared to levels after just a second dose in people aged 18-55 years, new data from Pfizer shows.
The third-dose immune response appears even more robust – more than 11 times higher than the second shot – among people aged 65-85 years.
The company noted this could mean an estimated 100-fold increase in Delta variant protection after a third dose. These new findings are outlined in a Pfizer second-quarter 2021 earnings report, which notes that the data are submitted for publication in a medical journal.
The data come from a relatively small number of people studied. There were 11 people in the 18- to 55-year-old group and 12 people in the 65- to 85-year-old group.
“These preliminary data are very encouraging as Delta continues to spread,” Mikael Dolsten, MD, chief scientific officer and president of the Worldwide Research, Development, and Medical organization at Pfizer, said during prepared remarks on a company earnings call July 28, CNN reported.
Availability of a third dose of any of the current COVID-19 vaccines would require amendment of the Food and Drug Administration’s emergency use authorization, or full FDA approval for the vaccine.
The possibility of a third dose authorization or approval has not been without controversy. For example, when Pfizer announced intentions to file for FDA authorization of a booster dose on July 8, the Centers for Disease Control and Prevention, the FDA, and the National Institutes of Health were quick to issue a joint statement saying they would decide when the timing is right for Americans to have a third immunization. The agencies stated, in part, “We are prepared for booster doses if and when the science demonstrates that they are needed.”
In addition, the World Health Organization said at a media briefing on July 12 that rich countries should prioritize sharing of COVID-19 vaccine supplies to other countries in need worldwide before allocating doses for a booster shot for its own residents.

“These preliminary data are very encouraging as Delta continues to spread,” Mikael Dolsten, MD, chief scientific officer and president of the Worldwide Research, Development, and Medical organization at Pfizer, said during prepared remarks on a company earnings call July 28, CNN reported.
Availability of a third dose of any of the current COVID-19 vaccines would require amendment of the Food and Drug Administration’s emergency use authorization, or full FDA approval for the vaccine.
The possibility of a third dose authorization or approval has not been without controversy. For example, when Pfizer announced intentions to file for FDA authorization of a booster dose on July 8, the Centers for Disease Control and Prevention, the FDA, and the National Institutes of Health were quick to issue a joint statement saying they would decide when the timing is right for Americans to have a third immunization. The agencies stated, in part, “We are prepared for booster doses if and when the science demonstrates that they are needed.”
In addition, the World Health Organization said at a media briefing on July 12 that rich countries should prioritize sharing of COVID-19 vaccine supplies to other countries in need worldwide before allocating doses for a booster shot for its own residents.

, according to a new study.
The July 28 preprint report of the study, which has not been peer reviewed, suggests a gradual “declining trend in vaccine efficacy” over 6 months after two doses of the Pfizer vaccine in more than 45,000 people worldwide.
The study finds overall effectiveness falls from 96% to 84%.
At the same time, a third booster dose of the Pfizer vaccine increases neutralizing antibody levels against the Delta variant by more than five times, compared to levels after just a second dose in people aged 18-55 years, new data from Pfizer shows.
The third-dose immune response appears even more robust – more than 11 times higher than the second shot – among people aged 65-85 years.

Reducing air pollution is linked to slowed brain aging and lower dementia risk
Xinhui Wang, PhD, assistant professor of research neurology, department of neurology, University of Southern California, Los Angeles.
, new research reveals. The findings have implications for individual behaviors, such as avoiding areas with poor air quality, but they also have implications for public policy, said study investigator,“Controlling air quality has great benefits not only for the short-term, for example for pulmonary function or very broadly mortality, but can impact brain function and slow memory function decline and in the long run may reduce dementia cases.”
The findings were presented at the 2021 Alzheimer’s Association International Conference.
New approach
Previous research examining the impact of reducing air pollution, which has primarily examined respiratory illnesses and mortality, showed it is beneficial. However, no previous studies have examined the impact of improved air quality on cognitive function.
The current study used a subset of participants from the Women’s Health Initiative Memory Study-Epidemiology of Cognitive Health Outcomes (WHIMS-ECHO), which evaluated whether postmenopausal women derive cognitive benefit from hormone therapy.
The analysis included 2,232 community-dwelling older women aged 74-92 (mean age, 81.5 years) who did not have dementia at study enrollment.
Researchers obtained measures of participants’ annual cognitive function from 2008 to 2018. These measures included general cognitive status assessed using the Telephone Interview for Cognitive Status-modified (TICSm) and episodic memory assessed by the telephone-based California Verbal Learning Test (CVLT).
The investigators used complex geographical covariates to estimate exposure to fine particulate matter (PM2.5) and nitrogen dioxide (NO2), in areas where individual participants lived from 1996 to 2012. The investigators averaged measures over 3-year periods immediately preceding (recent exposure) and 10 years prior to (remote exposure) enrollment, then calculated individual-level improvements in air quality as the reduction from remote to recent exposures.
The researchers examined pollution exposure and cognitive outcomes at different times to determine causation.
“Maybe the relationship isn’t causal and is just an association, so we tried to separate the timeframe for exposure and outcome and make sure the exposure was before we measured the outcome,” said Dr. Wang.
The investigators adjusted for multiple sociodemographic, lifestyle, and clinical characteristics.
Reduced dementia risk
The analysis showed air quality improved significantly for both PM2.5 and NO2 before study enrollment. “For almost 95% of the subjects in our study, air quality improved over the 10 years,” said Dr. Wang.
During a median follow-up of 6.2 years, there was a significant decline in cognitive status and episodic memory in study participants, which makes sense, said Dr. Wang, because cognitive function naturally declines with age.
However, a 10% improvement in air quality PM2.5 and NO2 resulted in a respective 14% and 26% decreased risk for dementia. This translates into a level of risk seen in women 2 to 3 years younger.
Greater air quality improvement was associated with slower decline in both general cognitive status and episodic memory.
“Participants all declined in cognitive function, but living in areas with the greatest air quality improvement slowed this decline,” said Dr. Wang.
“Whether you look at global cognitive function or memory-specific function, and whether you look at PM2.5 or NO2, slower decline was in the range of someone who is 1-2 years younger.”
The associations did not significantly differ by age, region, education, APOE ε4 genotypes, or cardiovascular risk factors.
Patients concerned about cognitive decline can take steps to avoid exposure to pollution by wearing a mask; avoiding heavy traffic, fires, and smoke; or moving to an area with better air quality, said Dr. Wang.
“But our study mainly tried to provide some evidence for policymakers and regulators,” she added.
Another study carried out by the same investigators suggests pollution may affect various cognitive functions differently. This analysis used the same cohort, timeframe, and air quality improvement indicators as the first study but examined the association with specific cognitive domains, including episodic memory, working memory, attention/executive function, and language.
The investigators found women living in locations with greater PM2.5 improvement performed better on tests of episodic memory (P = .002), working memory (P = .01) and attention/executive function (P = .01), but not language. Findings were similar for improved NO2.
When looking at air quality improvement and trajectory slopes of decline across cognitive functions, only the association between improved NO2 and slower episodic memory decline was statistically significant (P < 0.001). “The other domains were marginal or not significant,” said Dr. Wang.
“This suggests that brain regions are impacted differently,” she said, adding that various brain areas oversee different cognitive functions.
Important policy implications
Commenting on the research, Rebecca Edelmayer, PhD, senior director of scientific engagement, Alzheimer’s Association, said she welcomes new research on environmental factors that affect Alzheimer’s disease.
Whereas previous studies have linked longterm air pollution exposure to accumulation of Alzheimer’s disease-related brain plaques and increased risk of dementia, “these newer studies provide some of the first evidence to suggest that actually reducing pollution is associated with lower risk of all-cause dementia,” said Dr. Edelmayer.
Individuals can control some factors that contribute to dementia risk, such as exercise, diet, and physical activity, but it’s more difficult for them to control exposure to smog and pollution, she said.
“This is probably going to require changes to policy from federal and local governments and businesses, to start addressing the need to improve air quality to help reduce risk for dementia.”
