The recent death of “Black Panther” star Chadwick Boseman has resulted in colorectal cancer (CRC) screening guidelines receiving more attention. Mr. Boseman was diagnosed with Stage 3 CRC in 2016 and underwent treatment. He passed away 4 years later at the young age of 44.

Mr. Boseman’s death has highlighted two important concerns about current screening guidelines for CRC. These include racial disparities in patients with colon cancer and the fact that more younger patients are getting this disease.

There are at least three different sets of CRC screening recommendations from different trusted professional organizations that primary care physicians must decide how to follow. These organizations each published their guidelines indicating review of the best available evidence. On first glance there is discrepancy between these guidelines, but a closer look at them reveals they have a lot of similarities.

The U.S. Multi-Society Task Force of Colorectal Cancer (MSTF), which represents the American College of Gastroenterology, the American Gatroenterological Association, and the American Society for Gastrointestinal Endoscopy, is one of the organizations that offers guidelines. The MSTF recommends CRC screening for non-African American average risked persons at the age of 50 years (strong recommendation; moderate quality evidence). The first-tier options for this recommendation are to have a colonoscopy every 10 years or annual fecal immunochemial test. Additionally, the MSTF recommends beginning screening of African Americans at age 45 years (weak recommendation; very-low-quality evidence). This recommendation cites higher incidence rates, earlier mean age at onset, higher proportion of cancers before age 50 years and late-stage presentation. The MSTF indicates that the increased rate of CRC at an earlier age in African Americans is caused by a combination of biologic and societal factors, but do not point to what those are. This earlier screening is not backed by evidence that it in fact improves morbidity or mortality outcomes. The MSTF also address screening among high-risk individuals. Those with first degree relatives with CRC or advanced adenomas diagnosed before the age of 60 years should be screened beginning at age 40 years or 10 years younger than the age the relative was diagnosed, whichever comes first, according to the MSTF recommendations. These individuals should have a colonoscopy every 5 years, the MSTF says. Those with first degree relatives with CRC or advanced adenomas diagnosed at older than 60 years should have CRC beginning at 40 years, though with the same testing intervals as average-risk individuals.¹

The American College of Physicians (ACP) and the American Academy of Family Physicians (AAFP), however, endorse the guidelines set forth by the United States Preventive Services Task Force (USPSTF). These guidelines were published in 2016 in the JAMA and notably are currently under review. These guidelines recommend routine screening for those at average risk at the age of 50 years. In the publication of these guidelines, the increasing incidence of CRC in those under 50 was acknowledged. It is however stated that the modest benefit of earlier diagnosis made via screening is not better than the increased risk of increased lifetime colonoscopy.²

The publication specifically addresses the disparity among Black adults who have the highest incidence and mortality rates in comparison with other racial/ethnic groups. These guidelines specifically state that there are higher rates of colon cancer among black adults. They however clarify that they think it is because of decreased screening and treatment in this group. When compared with other groups and the screening and treatment is controlled for, there is no longer a difference. Lowering the age for starting screening, therefore, won’t help resolve the disparity because the higher cases in Black adults has resulted from not enough Black adults being screened at the recommended age of 50, according to the USPSTF recommendation statement. As such, rather than changing the age of screening for Black adults, this publication recommends efforts to ensure that screening, follow-up, and treatment are received.

The USPSTF specifically did not include adults with known disorders that have a genetic predisposition to CRC or those with a first degree relative with CRC. They instead refer to other professional organizations for these recommendations.²

The American Cancer Society (ACS) also had a separate guideline published in CA: A Cancer Journal for Clinicians. It provides a qualified recommendation that CRC screening begin at age 45 years for those with average risk. The guideline also includes a strong recommendation for CRC screening beginning at age 50 years. The qualified recommendation for the younger age group is based on the incidence of colorectal cancer being similar between those aged 45-49 and those aged 50-54 years. The ACS also hypothesized that screening at an earlier age will decrease the disparity among population groups with a higher burden. Importantly, this updated guideline prioritized incidence reduction rather than mortality reduction. The ACS also stressed the need for a multipronged approach to mitigate barriers to CRC screening at the individual, provider, organizational, and policy levels. Similar to the USPSTF, the ACS did not address the screening of those with known disorders that have a genetic predisposition to CRC or those with a first degree relative with CRC.³

In all of the publications discussing CRC screening guidelines, it is stressed that there is not sufficient uptake of any of these recommendations. Rather than conduct earlier screening, in my opinion, we should focus on programmatic ways to ensure that the existing screening recommendations are followed. This is a space in which we can help affect the disparity seen among population groups.

The most important screening test is the one that patients are willing to use. Primary care physicians can use any of these guidelines to have conversations with patients about risk and when to start screening. Although these guidelines may seem to be different from each other, each one includes strong recommendations with the same information.

Additional studies should be done to determine the benefits and harms of screening in patients with known risk factors such as obesity, cigarette smoking, diabetes, high consumption of alcohol, high consumption of red meat and processed food, inactivity, and low intake of dietary fiber, fruits, and vegetables. It is possible that the higher burden of disease among Black adults is related to societal factors leading to increased obesity and dietary habits that increase rates of CRC.

Primary care physicians would be better served by a tool that allows for risk stratification to help guide early screening for all patients. For certain patients, such a tool might result in them qualifying for screening that begins at a later age than the current guidelines recommend. Finally, primary care physicians must remember that these are just the guidelines for screening for CRC. They all specifically exclude patients experiencing any symptoms. As such, patients with unexplained bleeding, anemia, weight loss, and other symptoms should be evaluated fully, including being considered for colonoscopy to diagnose CRC. Primary care physicians should use these guidelines to screen their asymptomatic patients and should ensure that they provide evaluation of any of the symptoms of CRC.

Fully 48% of patients with autoimmune rheumatic diseases who developed persistent hypogammaglobulinemia after initiating treatment with immunomodulatory agents harbored gene variants associated with inborn errors of immunity, according to the findings of a single-center study published in Annals of the Rheumatic Diseases.

The results raise the possibility of a shared genetic etiology between “primary” and “secondary” hypogammaglobulinemia and suggest that some cases of autoimmune rheumatic disease may result from inborn errors of immunity. “In other words, a rheumatologist may be treating the rheumatic manifestations of a primary immunodeficiency disorder,” the study’s lead author, Georgios Sogkas, MD, PhD, said in an interview.

‘Striking’ findings suggest a future in personalized medicine

Experts who were not involved in the study called the results noteworthy. “The fact that half of patients with rheumatic disease who developed secondary hypogammaglobulinemia were found to have a functionally relevant mutation in a known PID gene is striking, albeit purely circumstantial given the absence of any functional or mechanistic data,” said Michael J. Ombrello, MD, principal investigator and head of the translational genetics and genomics unit at the National Institute of Arthritis and Musculoskeletal and Skin Diseases, who was not involved in the study.

The findings, if they are validated by additional studies, might help clinicians personalize medicine by avoiding hypogammaglobulinemia-inducing immunomodulatory regimens in genetically predisposed patients, or by targeting Janus kinase (JAK) inhibitor therapy for patients with STAT3 gain-of-function variants, or PI3K delta inhibitors for patients with variants leading to hyperactivation of the PI3Kdelta gene, Dr. Sogkas said.

Dr. Ombrello agreed: “Whether the hypogammaglobulinemia is classified as primary or secondary, the presence of these genetic variants in half of patients with hypogammaglobulinemia suggests an opportunity to improve clinical care. Although far off at this point, one can imagine a day where genetic data allows a rheumatologist to identify new-onset rheumatic disease patients carrying PID gene mutations and cater their therapy and monitoring accordingly.”

If further research validates these findings, they would add to a growing body of support for incorporating expanded or universal exome or genome sequencing in the care of medically complex patients, such as those with rheumatic diseases, Dr. Ombrello said. However, he cautioned that the investigators could have “overstated” the relationship in their study between secondary hypogammaglobulinemia and immunomodulatory treatment. The fact that a small group of study participants (about 7%) developed hypogammaglobulinemia after initiating immunomodulatory therapy does not confirm a causal relationship, he emphasized. Common variable immune deficiency (CVID) can develop in adults as late as the fifth and sixth decade of life, he noted, making it “not implausible that a small number of rheumatic disease patients would develop CVID while under the care of a rheumatologist. Would these patients have developed hypogammaglobulinemia even without treatment with immunomodulators, purely related to their genetic mutations? If so, they would be better classified as having primary immune deficiency, although that distinction is largely one of semantics.”

‘Rheumatologists are obliged to step up’

Interestingly, only 23% of the patients with hypogammaglobulinemia in the study had a clinically significant history of infections even though only 9% were receiving prophylactic antibiotics. Such findings highlight the complexity of PIDs, according to experts. “A long generation ago, we thought of immunodeficiencies as infections. Now we see them as autoimmune diseases, inflammatory diseases, allergic diseases – the spectrum continues to enlarge,” said Leonard H. Calabrese, DO, the RJ Fasenmyer chair of clinical immunology at the Cleveland Clinic, who was not involved in the study.

Dr. Calabrese noted that more than 450 monogenic variants have been linked to inborn errors of immunity. “Because these [PIDs] can mimic autoinflammatory presentations, rheumatologists are obliged to step up and gain a greater understanding, to be able to recognize and diagnose them and sort them out.”

Future goals should include quantifying the prevalence of genetic variants underlying hypogammaglobulinemia among patients with rheumatic diseases, and better characterizing outcomes and phenotypes of patients harboring variants linked to inborn errors of immunity, Dr. Sogkas said. “Whether these patients actually have a different disease than what they are being treated for, I can’t tell from this paper, and that’s an important question for the future,” added Dr. Calabrese. “I also do wonder about the effects of different drugs,” he said, noting that many patients with PID-associated autosomal gene variants developed persistent secondary hypogammaglobulinemia after initiating methotrexate. “It makes me wonder whether some of these genes have a specific interaction with methotrexate,” he said. “That could be a biomarker for drug toxicity.”

Study funders included the German Research Foundation, the German multiorgan Autoimmunity Network, Hannover Medical School, the Rosemarie-Germscheid Foundation, the German Academic Exchange Service, HBRS, the Center for Infection Biology, and the German Center for Infection Research. The investigators reported having no competing interests.

Dr. Calabrese noted that more than 450 monogenic variants have been linked to inborn errors of immunity. “Because these [PIDs] can mimic autoinflammatory presentations, rheumatologists are obliged to step up and gain a greater understanding, to be able to recognize and diagnose them and sort them out.”

Future goals should include quantifying the prevalence of genetic variants underlying hypogammaglobulinemia among patients with rheumatic diseases, and better characterizing outcomes and phenotypes of patients harboring variants linked to inborn errors of immunity, Dr. Sogkas said. “Whether these patients actually have a different disease than what they are being treated for, I can’t tell from this paper, and that’s an important question for the future,” added Dr. Calabrese. “I also do wonder about the effects of different drugs,” he said, noting that many patients with PID-associated autosomal gene variants developed persistent secondary hypogammaglobulinemia after initiating methotrexate. “It makes me wonder whether some of these genes have a specific interaction with methotrexate,” he said. “That could be a biomarker for drug toxicity.”

Study funders included the German Research Foundation, the German multiorgan Autoimmunity Network, Hannover Medical School, the Rosemarie-Germscheid Foundation, the German Academic Exchange Service, HBRS, the Center for Infection Biology, and the German Center for Infection Research. The investigators reported having no competing interests.

Bronchoscopy with intermittent apnea can be conducted safely for both patients with severe COVID-19 and health care workers, a recent study has found. In addition, the high rate of superinfection in these patients indicates that bronchoalveolar lavage (BAL) should sent to the lab if there is any suspicion for secondary pneumonia.

Those are two key findings from a single-center retrospective study led by Stephanie H. Chang, MD, that was published in CHEST.

“While there is a risk of aerosolization and transmission of COVID-19 with bronchoscopy, this can be mitigated with bronchoscopy under intermittent apnea and appropriate PPE [personal protective equipment] in a negative-pressure room, with no significant adverse patient outcomes and a 0% rate of transmission to health care workers,” Dr. Chang, a thoracic surgeon in the department of cardiothoracic surgery at New York University Langone Health, said in an interview. “In appropriate clinical scenarios that will significantly impact patient care, bronchoscopy can be and should be safely performed in patients with COVID-19.”

Although a recent statement from the American Association for Bronchoscopy & Interventional Pulmonology indicates that bronchoscopy is relatively contraindicated in patients with suspected and confirmed COVID-19 infections, it does support use of the procedure in a subset of such patients. It reads: “The only role for bronchoscopy would be when less invasive testing to confirm COVID-19 are inconclusive, suspicion for an alternative diagnosis that would impact clinical management is suspected, or an urgent lifesaving intervention.”

For the current study, Dr. Chang and colleagues retrospectively studied the records of 412 patients with confirmed COVID-19 who were admitted to NYU Langone Health’s Manhattan campus between March 13 and April 24, 2020. If these, 321 required intubation and 107 (33%) underwent bronchoscopy, with a total of 241 bronchoscopies being performed.

Primary outcomes of interest were patient and health care provider safety, defined as freedom from periprocedural complications and COVID-19 transmission, respectively. Secondary outcomes included secondary infection with bacterial or fungal pneumonia.

The bronchoscopy team included six cardiothoracic surgeons and four cardiothoracic surgery residents. Each procedure was performed by a sole bronchoscopist in a negative-pressure room, with a bedside nurse immediately available outside of the room. The bronchoscopist wore full PPE, which consisted of hair cover, a fitted N95 mask, a face shield, gown, and gloves. Each patient was preoxygenated for 2 minutes with a fraction of inspired oxygen at 1.0 in order to maximize apneic time. For patients who were not on sedation and/or neuromuscular blockade, periprocedural anesthesia with propofol and rocuronium was employed to decrease the risk of spontaneous breathing leading to aerosolization.

The bronchoscope used in all cases was the disposable Ambu aScope and a corresponding monitor. The device was used to clear all secretions, clot, or mucus plugs, and to collect bronchoalveolar lavage (BAL) samples. If oxygen saturation decreased below 90%, the bronchoscopist interrupted the procedure and reconnected the patient to the ventilator. After an additional period of preoxygenation, bronchoscopy was then completed.

The mean age of the 107 patients was 62 years, and 81% were male. Dr. Chang and colleagues reported that, of the 241 bronchoscopies performed, no periprocedural complication of severe hypoxia requiring bag-valve ventilation, pneumothorax, or intraprocedural arrhythmias occurred, and that three patients required endotracheal tube advancement or replacement for dislodgement during the procedure.

About half of patients (51%) received a BAL, and 35 (65%) had a positive culture. Among 23 patients who had a negative tracheal culture, 8 patients had a positive BAL, which indicated a 35% diagnostic yield for patients with negative tracheal aspirates. In addition, three patients had differing cultures between the BAL and tracheal aspirate. One was growing Pseudomonas and Klebsiella in the tracheal aspirate with Enterococcus in the BAL, while the other two patients were growing an extra pathogen (Escherichia coli or Serratia) in the BAL.

“The most surprising data was the 65% rate of secondary infection with BAL, which is significantly higher than the rate in standard patients with acute respiratory distress syndrome,” Dr. Chang said. “Additionally, the high rate of bronchoscopy (33% in intubated patients) is also significantly higher than that of standard viral ARDS patients. This increased rate of superimposed infection and need for bronchoscopy may be due to the abnormally thick secretions seen in patients with COVID-19.”

Of the 10 cardiothoracic surgery team members, 1 resident was COVID-19 positive by reverse transcriptase polymerase chain reaction (rtPCR) prior to performing any bronchoscopies. The remaining nine team members tested negative for COVID-19 via nasal pharyngeal swab for rtPCR assay, with at least one negative test performed 2 weeks after the last bronchoscopy performed during the study period.

“The use of apnea was well tolerated by the patients and likely contributed to the lack of transmission of COVID-19 to the health care providers,” Dr. Chang said. “Additionally, this work demonstrates a higher rate of superinfection with bacterial or fungal pneumonia, compared to other reports. It is also the only one that describes the false negative rate for negative tracheal aspirates, which is the current recommended diagnostic test for secondary pneumonia in patients with COVID-19.” She acknowledged certain limitation of the study, including its retrospective design. “Thus, the clinical impact of bronchoscopy on patient outcomes cannot be accurately assessed.”

Selexipag (Uptravi) does not change the level of daily activity of patients with pulmonary arterial hypertension (PAH), results from the phase 4 TRACE trial suggest.

“We had no preconceived idea if this drug would improve exercise capacity,” said Luke Howard, MD, of Imperial College Healthcare NHS Trust in London. It was clear, however, that 6-minute walk tests conducted a few times a year “don’t paint a picture of what daily life is like for patients on selexipag.”

The oral prostacyclin IP receptor agonist is prescribed to slow the progression of PAH and reduce hospital admissions, but there are no studies that show whether it improves quality of life.

Dr. Howard and his team turned to wearable technology to “capture a snapshot of everyday life,” he explained during his presentation at the annual meeting of the American College of Chest Physicians (CHEST 2020), held virtually this year.

The primary concern of the investigators was to get TRACE participants – all with PAH – to wear a wrist device; they did not encourage patients to become more active. “We wanted a true picture of the impact of the drug itself,” he noted.

After 24 months of daily tracking, “there was no benefit to increased daily activity for patients taking this drug,” Dr. Howard said in an interview. “That was a bit deflating.”

The daily activity of TRACE participants was “slightly more elevated” in the selexipag group than in the placebo group. “We saw some numerical drops in activity in the placebo group, and a trend that might make a difference over a longer, bigger study, but not in a statically significant way,” he reported.

In the randomized, blinded trial – the first to track the activity of PAH patients – 53 participants received selexipag and 55 received placebo. All 108 wore a wrist accelerometer (GT9X Link) that counted the number of steps taken each day, providing an indication of daily activity.

Device compliance – the mean number of days in which the device was worn for at least 7 hours during a 14-day predrug period – was similar in the selexipag and placebo groups (13.2 vs 13.0 days).

“We wanted to make sure we had people who were stable and weren’t enrolled in a rehabilitation program; we didn’t want any competing influences,” Dr. Howard explained. All in all, the participants were in pretty good shape. “There was a low risk of a bad outcome.”

The primary endpoint was change in activity from baseline to week 24. The secondary endpoints were PAH-SYMPACT health quality-of-life tests and 6-minute walk distance.
 

Similar activity levels in both groups

As expected in a population in which the majority of patients meet the criteria for WHO functional class II PAH, all participants had low PAH-SYMPACT domain scores throughout the trial.

All adverse events were “consistent with the known profile” of selexipag, and there were no deaths, Dr. Howard reported.

“We did not show any significant benefit to taking the drug,” he said, but the drug is marketed for the prevention of disease progression, and this finding “doesn’t change that.”
 

Pulmonary rehabilitation

“Pulmonary rehabilitation is one of the most vital management issues with chronic lung disease,” Riddhi Upadhyay, MD, of Carle Foundation Hospital in Urbana, Ill., said during her CHEST 2020 presentation on improving PAH rehabilitation referral rates.

“We know it improves exercise capacity, lung function, and decreases total hospital stays and recurrent hospital admission,” she explained. And studies have shown that PAH rehabilitation “also reduces frailty and improves quality of life.”

In their study, Dr. Upadhyay and colleagues showed that when pulmonary rehabilitation is added to the discharge order set, referrals increase by 60%.

They attribute their success to “recognizing the benefits of pulmonary rehab and understanding where interventions are required.”

An encouraging takeaway from the TRACE data is that it established that daily activity can be tracked in this patient population. “We think we might need to encourage these patients to get active, maybe combine the drug with a formal rehabilitation program; that might increase motivation,” Dr. Howard said.

“People don’t necessarily do more just because they can,” he noted.

The Brazilian National Health Surveillance Agency (Anvisa) announced Oct. 21 that it is investigating data received on the death of a volunteer in a clinical trial of the COVID-19 vaccine developed by Oxford University and the pharmaceutical company AstraZeneca.

In an email sent to Medscape Medical News, the agency states that it was formally informed of the death on October 19. It has already received data regarding the investigation of the case, which is now being conducted by the Brazilian International Security Assessment Committee.

The identity of the volunteer and cause of death have not yet been confirmed by any official source linked to the study. In the email, Anvisa reiterated that “according to national and international regulations on good clinical practices, data on clinical research volunteers must be kept confidential, in accordance with the principles of confidentiality, human dignity, and protection of participants.”

A report in the Brazilian newspaper O Globo, however, states that the patient who died is a 28-year-old doctor, recently graduated, who worked on the front line of combating COVID-19 in three hospitals in Rio de Janeiro. He reportedly died Oct. 15 due to complications from COVID-19. The newspaper report said he received a dose of the AZDI222 vaccine in late July. Due to the study design, it is impossible to know whether the volunteer received the vaccine or placebo.

It is imperative to wait for the results of the investigations, said Sergio Cimerman, MD, the scientific coordinator of the Brazilian Society of Infectious Diseases (SBI), because death is possible during any vaccine trial, even more so in cases in which the final goal is to immunize the population in record time.

“It is precisely the phase 3 study that assesses efficacy and safety so that the vaccine can be used for the entire population. We cannot let ourselves lose hope, and we must move forward, as safely as possible, in search of an ideal vaccine,” said Cimerman, who works at the Instituto de Infectologia Emílio Ribas and is also an advisor to the Portuguese edition of Medscape.

We cannot let ourselves lose hope, and we must move forward, as safely as possible, in search of an ideal vaccine,” said Cimerman, who works at the Instituto de Infectologia Emílio Ribas and is also an advisor to the Portuguese edition of Medscape.

The Brazilian National Health Surveillance Agency (Anvisa) announced Oct. 21 that it is investigating data received on the death of a volunteer in a clinical trial of the COVID-19 vaccine developed by Oxford University and the pharmaceutical company AstraZeneca.

In an email sent to Medscape Medical News, the agency states that it was formally informed of the death on October 19. It has already received data regarding the investigation of the case, which is now being conducted by the Brazilian International Security Assessment Committee.

The identity of the volunteer and cause of death have not yet been confirmed by any official source linked to the study. In the email, Anvisa reiterated that “according to national and international regulations on good clinical practices, data on clinical research volunteers must be kept confidential, in accordance with the principles of confidentiality, human dignity, and protection of participants.”

A report in the Brazilian newspaper O Globo, however, states that the patient who died is a 28-year-old doctor, recently graduated, who worked on the front line of combating COVID-19 in three hospitals in Rio de Janeiro. He reportedly died Oct. 15 due to complications from COVID-19. The newspaper report said he received a dose of the AZDI222 vaccine in late July. Due to the study design, it is impossible to know whether the volunteer received the vaccine or placebo.

Neutrophil granulocyte biomarkers can distinguish between neuromyelitis optica spectrum disorders (NMOSD) and anti-MOG antibody–associated disease (MOGAD) on one hand and multiple sclerosis (MS) on the other hand, researchers reported. If current findings are replicated, these biomarkers will help neurologists distinguish between these disorders in the future, even in cases that are negative for autoantibodies, they said.

The sensitivity and specificity profile of neutrophil granulocyte biomarkers is not as good as that for cell-based assays for AQP4 and anti-MOG antibodies when it comes to distinguishing between acute NMOSD or MOGAD versus acute relapsing-remitting MS, said David Leppert, MD, of University Hospital Basel (Switzerland) and the University of Basel. But the sensitivity and specificity of neutrophil granulocyte biomarkers are “even with” those of referring ELISA tests, he added. Furthermore, the evaluation of these biomarkers can be completed within hours, thus providing the potential for timely support for therapeutic decisions about patients with acute NMOSD.

It can be difficult to distinguish between NMOSD, MOGAD, and MS using a clinical examination and MRI scans alone. Assays for AQP4 and anti-MOG antibodies are the standard for refining the diagnosis, but obtaining the results of these assays takes 1-2 weeks. This time frame may delay the administration of urgently needed treatment.

Neutrophil granulocytes have various components that carry molecules that, although they are secreted to defend the host, also can damage tissue. These cells are common in brain tissue and CSF among patients with NMOSD. Patients with MOGAD often have neutrophil granulocytes as well, but the latter are rare in MS.
 

Biomarkers had high AUC

Dr. Leppert and colleagues conducted a study to evaluate whether these cells can distinguish NMOSD or MOGAD from MS. The investigators specifically examined the following neutrophil granule products: elastase, myeloperoxidase (MPO), matrix metalloproteinase-8 (MMP-8), and neutrophil gelatinase-associated lipocalin (NGAL). Dr. Leppert’s group evaluated CSF samples from 42 patients with NMOSD, 6 patients with MOGAD, and 41 patients with relapsing-remitting MS for these potential biomarkers. They also examined the samples for neurofilament light (NfL), glial fibrillary acidic protein (GFAP), and S100B by conventional ELISA or single-molecule array assay. The investigators examined CSF samples from 25 healthy controls as a reference group.

Linear models allowed Dr. Leppert and colleagues to assess the association between biomarkers and disease groups. The investigators modeled the change of biomarker levels over time. They calculated receiver operating characteristic (ROC) curves and area under the curve (AUC) to estimate the potential to distinguish NMOSD and MOGAD from relapsing-remitting MS in acute disease phase (i.e., at 20 or fewer days after relapse), as well as between acute NMOSD and MOGAD. Finally, they assessed the association of biomarkers with Expanded Disability Status Scale (EDSS) score in acute NMOSD and relapsing-remitting MS using linear models and Spearman correlation.

Dr. Leppert and colleagues found that levels of NfL were increased among patients, compared with healthy controls. GFAP levels were increased in patients with NMOSD, compared with controls.

Among patients with NMOSD, all four neutrophil granulocyte markers were significantly increased, compared with healthy controls and patients with acute relapsing-remitting MS. Among patients with MOGAD, elastase, MPO, and MMP-8 were increased, compared with healthy controls and patients with acute relapsing-remitting MS. In ROC analyses comparing patients with acute NMOSD or MOGAD against those with acute RRMS, the AUC of elastase and NGAL was 0.91, the AUC of MPO was 0.82, and the AUC of MMP-8 was 0.81.

Levels of S100B were increased in 89% of patients with acute NMOSD (AUC = 0.82), and levels of GFAP were increased in 83% of patients with acute NMOSD (AUC = 0.80), compared with median values of MOGAD. Among patients with acute NMOSD, EDSS scores correlated with all four neutrophil granulocyte markers and GFAP, but not with NfL and S100B. The neutrophil granulocyte markers in acute NMOSD are likely drivers of tissue damage, said Dr. Leppert. “We may end up in the future with an algorithm that combines several markers into one score to optimize the differentiating power.” The next step will be to validate these findings in a larger sample set, he said at the Joint European Committee for Treatment and Research in Multiple Sclerosis–Americas Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS-ACTRIMS) 2020, this year known as MSVirtual2020.
 

Biomarkers may predict attacks

Granulocyte markers may provide support for a diagnosis of NMOSD over MS even in the small subgroup of patients who are seronegative for AQP4-IgG and MOG-IgG, said Brian G. Weinshenker, MD, a neurology consultant at Mayo Clinic in Rochester, Minn. In the study by Leppert and colleagues, granulocyte markers did not appear able to distinguish patients with AQP4-IgG–associated NMOSD from those with MOG-IgG–associated NMOSD, although astrocyte markers did in previous studies. “Granulocyte markers are primarily effective when studied in the context of an acute attack, unlike the antibody biomarkers,” said Dr. Weinshenker.

“Perhaps the most promising aspect of these new biomarkers is the fact that they are biomarkers for important mediators of tissue toxicity and seemed to correlate with attack-related disability,” he added. “They may prove to be prognostic indicators of attacks, and might influence the aggressiveness of acute management of attacks, although, in practice, all patients with NMOSD attacks, especially those associated with AQP4-IgG, should be managed aggressively.”

The current results will need independent confirmation before these biomarkers can be integrated into clinical practice, said Dr. Weinshenker. Studies should include patients with other diseases that can cause inflammation in the spinal cord and optic nerve (e.g., acute disseminated encephalomyelitis, infectious myelitis, and parainfectious myelitis) as relevant controls to determine whether granulocyte markers can distinguish these conditions effectively.

In addition, patients with discrepant values for elevations of granulocyte markers and serological indicators of NMOSD should be followed to determine the markers’ significance in this population, as well as to understand the value that measuring neutrophil markers provides. “Further studies of how these markers might herald attacks and predict disability might render these tests useful in monitoring patients and potentially intervening early in the attack process before attacks are fully manifest clinically.”

Dr. Leppert did not report any disclosures or any outside funding for the study. Dr. Weinshenker receives royalties from RSR, Oxford University, Hospices Civil de Lyon, and MVZ Labor PD Dr. Volkmann und Kollegen for a patent on NMO-IgG as a diagnostic test for NMOSD. He has served on an adjudication committee for clinical trials in NMOSD being conducted by MedImmune/VielaBio and Alexion, and consulted for Chugai/Roche/Genentech and Mitsubishi-Tanabe regarding a clinical trial for NMOSD.

While the spring peak of COVID-19 was tough and traumatic for many residents and interns in a New York City health system, the experience may have accelerated their patient communication skills regarding difficult goals-of-care discussions, results of a recent survey suggest.

Breaking bad news was an everyday or every-other-day occurrence at the peak of the pandemic for nearly all of 50 of the trainees surveyed, who had worked at hospitals affiliated with the internal medicine residency program at the at the Icahn School of Medicine at Mount Sinai from March to June 2020.

However, trainees became significantly more comfortable and fluent in goals-of-care discussions during the pandemic, according to Patrick Tobin-Schnittger, MBBS, a third-year internal medicine resident in the Mount Sinai program.

“COVID-19 has obviously made a huge impact on the world, but I think it’s also made a huge impact on a whole generation of junior doctors,” said Dr. Tobin-Schnittger, who presented the findings in a late-breaking abstract session at the CHEST Annual Meeting, held virtually this year.

“It’ll be interesting to see what happens in the future as that generation matures, and I think one of the things is that we’re a lot more comfortable with end-of-life care,” he said in an interview conducted during the conference.

Nevertheless, coping with death may still be a challenge for many residents, according to Dr. Tobin-Schnittger. In the survey, internal medicine residents who had rarely encountered patient deaths suddenly found themselves experiencing deaths weekly, with more than one in five saying they were encountering it every day.

When asked to self-rate themselves according to Bugen’s Coping With Death scale, most participants had scores that suggested their ability to cope was suboptimal, the researcher said.

To help trainees cope with local COVID-19 surges, internal medicine residency programs should be implementing “breaking bad news” workshops and educating house staff on resilience in times of crisis, especially if it can be done virtually, according to Dr. Tobin-Schnittger.

“That could be done pretty quickly, and it could be done remotely so people could practice this from home,” he explained. “They wouldn’t even need to congregate in a big room.”

As a “mini-surge” of COVID-19 cases hits the United States, teaching self-care and coping techniques may also be important, said Mangala Narasimhan, DO, FCCP, director of critical care services at Northwell Health in New York City.

A mini-sponge tamponade device controlled postpartum hemorrhage within 1 minute of placement, according to data from a study of nine women.

Postpartum hemorrhage remains a leading cause of maternal deaths worldwide; however, “nearly all of these deaths could be prevented by timely and appropriate management,” wrote Maria I. Rodriguez, MD, of Oregon Health & Science University, Portland, and colleagues. Other strategies including use of sterile gauze, inflated Foley catheters, condom catheters, and silicone obstetric balloons, have been tried in the management of postpartum hemorrhage, but are not ideal, the researchers said.

The investigators adapted a mini-sponge device originally designed for trauma and conducted a study of a prototype between May 20 and June 12, 2019, at a single site in Zambia.

“To adapt the mini-sponge device for use in the treatment of postpartum hemorrhage, we developed an obstetric applicator for transcervical placement using a digital vaginal route,” the researchers explained. The sponges are made of the same material used in standard surgical sponges and approved for use inside the uterus and vagina, they added.

In a study published in Obstetrics & Gynecology, the investigators assessed placement, removal, and preliminary efficacy of the device. Eligible patients were women aged 16 years and older who experienced postpartum hemorrhage with an estimated blood loss of 500 mL or more because of atony after vaginal delivery.

The device was successfully placed in nine patients, and bleeding resolved within 1 minute. “For all participants, bleeding stopped in less than 1 minute, did not recur, and required no further treatment,” the researchers said.

The average time to device placement was 62 seconds. The sponges were left in place from 0.5 hours to 14 hours with an average of 1 hour, and patients were monitored with physical, visual, and ultrasound to confirm the cessation of bleeding.
 

Evidence of safety

No device-related adverse events were reported, and patients remained afebrile while using the device. The average age of the patients was 29 years; three had a history of anemia and four were living with HIV. One patient received a blood transfusion during labor prior to hemorrhage.

The study findings were limited by the small sample size, the low threshold for diagnosing postpartum hemorrhage, and use of estimated blood loss, which is less precise than quantitative blood loss assessment, the researchers noted. However, the results support the use of the mini-sponge tamponade to treat atonic postpartum hemorrhage, they said.

“This device is being developed to offer a low-cost, easy-to-use product that is of similar or greater efficacy than the condom uterine balloon tamponade,” needs no electricity, and could be used in low-resource areas, they said.

A larger study comparing the sponge and condom uterine balloon tamponade is planned.

“Future studies will include a larger number of participants with quantitative blood loss assessment to determine the device’s effect in managing more patients with severe postpartum hemorrhage,” the investigators noted.
 

Rigorous research needed

“Uterine atony is too often disastrous, and new safe and effective treatments for it would be welcome,” Dwight J. Rouse, MD, associate editor of obstetrics for Obstetrics & Gynecology, wrote in an accompanying editorial.

The current balloon tamponade used to treat postpartum hemorrhage can be difficult to place and require ongoing monitoring, he said.

Although the mini-sponge device showed promise, the study was not randomized or controlled, thus lacking in evidence of effectiveness, said Dr. Rouse.

“We simply know that the participants had the devices placed and most of them stopped bleeding,” he said.

The mechanism of action is sound, but more research is needed, especially in light of other examples of new technologies, such as adhesion barriers and negative pressure wound dressing systems after cesarean deliveries, that “made sense in the abstract but failed to improve outcomes when evaluated in proper randomized trials,” Dr. Rouse noted.

“Absent such trials, we will never really know the relative value of any device to treat uterine atony refractory to medical management,” he said.

Lead author Dr. Rodriguez disclosed that her institution received funding from OBSTETRX, which funded the study, as well as the National Institutes of Health and Merck. Dr. Rodriguez disclosed funding from Bayer, while Dr. Rouse had no financial conflicts to disclose.

A mini-sponge tamponade device controlled postpartum hemorrhage within 1 minute of placement, according to data from a study of nine women.

Postpartum hemorrhage remains a leading cause of maternal deaths worldwide; however, “nearly all of these deaths could be prevented by timely and appropriate management,” wrote Maria I. Rodriguez, MD, of Oregon Health & Science University, Portland, and colleagues. Other strategies including use of sterile gauze, inflated Foley catheters, condom catheters, and silicone obstetric balloons, have been tried in the management of postpartum hemorrhage, but are not ideal, the researchers said.

The investigators adapted a mini-sponge device originally designed for trauma and conducted a study of a prototype between May 20 and June 12, 2019, at a single site in Zambia.

“To adapt the mini-sponge device for use in the treatment of postpartum hemorrhage, we developed an obstetric applicator for transcervical placement using a digital vaginal route,” the researchers explained. The sponges are made of the same material used in standard surgical sponges and approved for use inside the uterus and vagina, they added.

In a study published in Obstetrics & Gynecology, the investigators assessed placement, removal, and preliminary efficacy of the device. Eligible patients were women aged 16 years and older who experienced postpartum hemorrhage with an estimated blood loss of 500 mL or more because of atony after vaginal delivery.

The device was successfully placed in nine patients, and bleeding resolved within 1 minute. “For all participants, bleeding stopped in less than 1 minute, did not recur, and required no further treatment,” the researchers said.

The average time to device placement was 62 seconds. The sponges were left in place from 0.5 hours to 14 hours with an average of 1 hour, and patients were monitored with physical, visual, and ultrasound to confirm the cessation of bleeding.
 

Evidence of safety

No device-related adverse events were reported, and patients remained afebrile while using the device. The average age of the patients was 29 years; three had a history of anemia and four were living with HIV. One patient received a blood transfusion during labor prior to hemorrhage.

The study findings were limited by the small sample size, the low threshold for diagnosing postpartum hemorrhage, and use of estimated blood loss, which is less precise than quantitative blood loss assessment, the researchers noted. However, the results support the use of the mini-sponge tamponade to treat atonic postpartum hemorrhage, they said.

“This device is being developed to offer a low-cost, easy-to-use product that is of similar or greater efficacy than the condom uterine balloon tamponade,” needs no electricity, and could be used in low-resource areas, they said.

A larger study comparing the sponge and condom uterine balloon tamponade is planned.

“Future studies will include a larger number of participants with quantitative blood loss assessment to determine the device’s effect in managing more patients with severe postpartum hemorrhage,” the investigators noted.
 

Rigorous research needed

“Uterine atony is too often disastrous, and new safe and effective treatments for it would be welcome,” Dwight J. Rouse, MD, associate editor of obstetrics for Obstetrics & Gynecology, wrote in an accompanying editorial.

A new analysis of the Swedish Obese Subjects (SOS) study shows that bariatric surgery is associated with about a 3-year increase in lifespan, compared with obese patients who do not undergo surgery. Still, surgery did not restore normal lifespan: Surgical patients’ lifespan remained less than that of a sample from the general Swedish population. The study follows other reports suggesting reduced mortality after bariatric surgery, but with a longer follow-up.

“These data add even more evidence to the growing literature showing that patients who undergo bariatric surgery experience a reduction in all-cause long-term mortality. In making decisions around bariatric surgical procedures and care, patients and their health care providers need to understand the trade-offs between improved weight, health, and longer-term survival versus the surgical risks and problems over time,” said Anita P. Courcoulas, MD, MPH, chief of minimally invasive bariatric and general surgery at the University of Pittsburgh Medical Center, said in an interview. Dr. Courcoulas was not involved in the study.

The results appeared in the New England Journal of Medicine.

The SOS study drew from 25 surgical departments and 480 primary health care centers in Sweden. The researchers examined data from 2,007 patients who underwent bariatric surgery between 1987 and 2001, and compared their outcomes to 2,040 matched controls. All were between age 37 and 60 years, with a body mass index (BMI) of at least 34 kg/m² for men and 38 for women. They also compared outcomes with 1,135 randomly sampled from the Swedish population registry.

Procedures included banding (18%), vertical banded gastroplasty (69%), and gastric bypass (13%). After an initial BMI reduction of about 11, the surgery group stabilized by year 8 at a BMI about 7 lower than baseline, and there was little change in BMI among controls.

After a mean follow-up of 24 years (interquartile range, 22-27 years), there were 10.7 deaths per 1,000 person-years in the surgery group, 13.2 among obese controls, and 5.2 in the general population (hazard ratio, 0.77 for surgery versus no surgery; P < .001). The general population had a lower mortality than nonsurgical controls (HR, 0.44; P < .001).

The surgery group had a higher median life expectancy than controls (median, 2.4 years; adjusted difference, 3.0 years; P < .001). The general population group had a median life expectancy that was 7.4 years higher than the control group (adjusted difference, 8.5 years; P < .001). The surgery group’s median life expectancy was still shorter than the general population reference (adjusted difference, 5.5 years; P < .001).

Cardiovascular disease risk was lower in the surgery group (HR, 0.70; 95% confidence interval, 0.57-0.85), as was risk of MI (HR, 0.51; 95% CI, 0.33-0.79), heart failure (HR, 0.52; 95% CI, 0.31-0.88), and stroke (HR, 0.45; 95% CI, 0.24-0.84). Cancer mortality was also lower (HR, 0.77; 95% CI, 0.61-0.96).

In the surgery group, causes of death that were elevated over the general population included cardiovascular causes (HR, 2.64; 95% CI, 1.78-3.91) and noncardiovascular causes, mainly infections; postsurgical complications; and factors such as alcoholism, suicide, or trauma (HR, 1.50; 95% CI, 1.18-1.91).

The study is limited by its retrospective nature, and because the surgical techniques used at the time are less effective than those used today, and could lead to weight gain over time. As a result, many patients who underwent surgery remained heavier than the general population. It’s also possible that negative health effects accumulated before surgery and persisted afterwards, according to Dr. Courcoulas.

The findings are likely generalizable to people with obesity, many of whom choose not to undergo bariatric surgery despite the potential benefits. “The population studied in SOS had a similar profile of underlying medical diseases to those groups who undergo bariatric surgery today and in the U.S. and around the world,” said Dr. Courcoulas.

The study was funded by the Swedish Research Council and others. Dr. Courcoulas has no relevant financial disclosures
