Seward Professor Chair of Family Medicine Director of population health University of Virginia School of Medicine Editor-in-chief of The BMJ Family Medicine Dr. Li joined the U.S. Preventive Services Task Force in January 2021 MedicalResearch.com: What is the background for this study? What are the main findings of the underlying studies? Response: Falls are the leading cause of injuries in older adults and can lead to serious disability and even death. To help prevent these incidents, the Task Force looked at the current evidence on ways that primary care clinicians can help prevent falls in adults aged 65 and older who live at home and are more likely to fall. We concluded that healthcare professionals should recommend exercise interventions for adults aged 65 and older who are at increased risk for falls. This could include gait, balance, and functional training, as well as strength, resistance, and flexibility training. Clinicians can also talk with their older patients who are most likely to fall about whether additional interventions might be helpful to reduce their risk of falling.

Would you briefly describe what is meant by preeclampsia? Response: Preeclampsia is a complication of the second half of pregnancy, manifesting as high blood pressure and renal dysfunction. The only current treatment is to deliver the baby before it becomes complicated by damage to maternal organs or fetal distress. A few years ago, we demonstrated that aspirin started in the 1st trimester can prevent the majority of preeclampsias in pregnant women at risk. It has therefore become urgent to identify pregnant women at risk as early as the 1st trimester.

  • Antibiotic resistance, which occurs when germs like bacteria and fungi mutate to defeat the drugs designed to kill them, is a major public health threat.
  • Data show that 40-50% of patients hospitalized with pneumonia receive broad spectrum antibiotics when they do not need them.
  • Helping clinicians tailor antibiotic prescriptions to individual patients can improve patient outcomes by preserving healthy bacteria in the body and reducing the risk of future antibiotic resistance.

Response: Prior studies have found that female and male physicians practice medicine differently. For example, female physicians are, on average, more likely to abide by clinical guidelines and spend more time listening to patients. However, evidence was limited as to whether such differences have clinically meaningful impact on patients’ health outcomes, which was the aim of this study.
Author Interviews, COVID -19 Coronavirus, JAMA, Technology, UCSD, Vaccine Studies / 25.04.2024

MedicalResearch.com Interview with: John W. AyersJohn W. Ayers, PhD MA Vice Chief of Innovation | Assoc. Professor
Div. Infectious Disease & Global Public Health University of California San Diego Since the World Health Organization declared an ‘infodemic’ of misinformation, there have been surprisingly few achievements to celebrate. X's Community Notes have emerged as an innovative strategy to address misinformation as reported in the latest issue of JAMA.
Before the inception of Community Notes, social media companies employed various tactics to tackle misinformation, including censoring, shadowbanning (muting a user or their content on a platform without informing them), and adding generic warning labels to problematic content. However, these efforts were typically undisclosed meaning their effectiveness could not be studied.

In late 2022, X introduced Community Notes. This novel approach empowers volunteer, independent, anonymous, and ideologically diverse contributors to identify posts containing misinformation and to rectify misinformation by appending informative "notes" to suspect posts. The process is controlled by the public, instead of decision-makers at the company. Most importantly the system is open-sourced so it can be studied by external scientists.

Author Interviews, Autism, Nature, Pediatrics / 11.04.2024

MedicalResearch.com Interview with: [caption id="attachment_50547" align="alignleft" width="200"]Andrey Vyshedskiy PhD Boston University, Boston Dr. Vyshedskiy[/caption] Dr. Andrey Vyshedskiy, PhD Founder and CEO of ImagiRation LLC Neuroscientist, Boston University MedicalResearch.com: What is the background for this study? Response: The common intuitive belief is that language comprehension development follows a linear trajectory: children acquire one grammatical rule at a time. Over 20 years ago, Dr. A. Vyshedskiy, predicted that instead of linear development, language should unfold in three steps corresponding to three language comprehension mechanisms of increasing complexity. The study of 31845 autistic individuals, published today in the journal npj Mental Health Research, validates this prediction. The implications of this discovery are reaching far and wide. The traditional definition of language is highly ambiguous. For some philosophers, “language” is equivalent to a “communication system.” Others argue that “language” must be defined more narrowly, in a way that is unique to humans. The results of the new study streamline terminology for describing different language comprehension mechanisms. The ensuing discussion of which language comprehension mechanisms are unique to humans and which are shared with other apes is expected to be most interesting.

Huang, MD, MPH Chancellor's Professor, Infectious Diseases School of Medicine Department of Epidemiology and Infection Prevention University of California Irvine School of Medicine, Irvine MedicalResearch.com: What is the background for this study? Would you describe the decolonization techniques?  
  • This study arose from a growing concern about the increasing number and presence of antibiotic-resistant bacteria causing colonization and infection in hospitals and long-term care. CDC has had a longstanding interest in the value of regional control of these contagious pathogens and they funded this study. The study was actually in two parts:
    • –1) Simulate various infection prevention strategies in a model and see which works best, and then
    • - 2) Do it in real life. The SHIELD project was the real-life example of our simulation finding that decolonization would work the best to prevent harm from antibiotic-resistant bacteria.
  • The regional idea is that it takes all of us working together – hospitals, nursing homes, and long-term acute care hospitals – to prevent the spread and sharing of contagious pathogens. What we can accomplish together is far greater than what any of us can do alone.
  • In this study, decolonization was the use of topical chlorhexidine antiseptic soap and povidone-iodine nasal ointments to reduce potentially harmful bacteria on the body during times when patients and residents may be at risk for infection. We swapped out bathing and showering soap with CHG in participating facilities and ensured that staff knew to clean the body well, including wounds, devices, and rashes where germs can hide and cause infection. For CHG, this involved 4% rinse off product in the shower and 2% no-rinse CHG for bed baths.

Response: Psoriasis is a skin inflammatory disease that affects approximately 2-3% of the population. Previous research had identified that the cytokine IL-17 drives the development of this disease. However, key questions that remained unknown about psoriasis included where did the IL-17 come from, and why do some patients with psoriasis also go on to develop systemic inflammatory conditions such as arthritis. Our research aimed to address these questions using a gain of function (GoF) mouse model that carried a genetic variant in a gene called IKBKB.

Response: Our work was prompted by emerging concerns surrounding the potential nephrotoxic effects of hair-straightening products containing glyoxylic acid. This inquiry was instigated by a patient who experienced three repeated acute episodes of kidney injury in June 2020, April 2021, and July 2022, each occurring shortly after a hair-straightening procedure. Notably, these episodes resolved with hydration. Upon examining the composition of the hair product used by the patient, which contained glyoxylic acid, and considering the patient's report of  painful ulcer scalp during application and subsequent scalp scarring, we suspected a potential link between exposure to glyoxylic acid and kidney injury. Consulting with my colleague, Professor Emmanuel Letavenier, a specialist in crystalline nephropathy at Paris, confirmed this suspicion. In summer 2023, cases series have been reported by an Israeli team (https://pubmed.ncbi.nlm.nih.gov/36610611/), who described 26 patients presenting with acute renal injuries after hair straightening treatments. Biopsies revealed calcium oxalate crystals in the kidneys. The Israeli researchers suspected an effect of formaldehyde and glycolic acid, another substance found in many cosmetic products, including hair straightening products, but were unable to provide conclusive evidence.

Chan School of Public HealthBoston, MA 02115   MedicalResearch.com: What is the background for this study? Response: In a study published in Science in 2022, we reported compelling evidence that infection with the Epstein-Barr virus is the leading cause of Multiple Sclerosis. This is a follow-up study to investigate more in depth whether the antibody response to EBV is distinct in individuals with MS compared to individuals without MS and whether there is a part of EBV that the immune response is particularly targeting. For this purpose we assessed the immune response to all protein parts (peptides) of EBV and their association with MS. Previous studies could only look at parts of EBV and this is the first study looking at all EBV peptides. Antibodies to EBV (especially to a protein called EBNA1) are known to be overall higher in individuals with MS, so we also tested whether immune response overall or the immune response to specific EBV protein parts was more important. If the immune response to a specific EBV protein part (peptide) would be standing out or distinguishing individuals with MS, we hypothesized, it could point to a specific mechanism of how EBV may cause MS, i.e. it could point for example towards “molecular mimicry”, which is when antibodies targeting a pathogen start targeting a body-own structure (for example in the brain) which resembles the protein parts of the pathogen.

Response: This study was performed in the backdrop of recent colorectal cancer screening guideline updates.  Two national organizations are recommending screening initiation at two different ages: USPSTF recommends initiation at age 45 and the American College of Physicians (ACP) recommends initiation at age 50. With now two national organizations recommending different ages to start screening, patients may become confused (particularly those between 45-50).  Prior confusion has been documented when breast cancer screening recommendations were being changed as well.  Our focus was to examine colorectal adenocarcinoma incidence rates with stage stratification of those who are between the ACP and USPSTF recommendations (ages 46-49). Our study utilized SEER17 data registries over 2000-2020 to collect incidence rates within the U.S.

What are the main findings? Dr. Fangqun Yu: Legionnaires’ disease is a severe form of pneumonia with a fatality rate of 10-25% caused by inhaling or aspirating Legionella, bacteria that thrive in built environment water systems. Those most vulnerable to this disease are male, over 50 years of age, have a history of smoking, have chronic respiratory diseases, diabetes, are immunocompromised, and/or minorities. The US observed a nearly nine-fold increase in Legionnaires’ disease between 2000 and 2018, with New York State having one of the highest increases in disease rates. The reasons for the increase in incidence were unclear prior to this study. In our study, we found: (1) Declining sulfur dioxide concentrations (SO2) are strongly correlated with the increase in legionellosis cases and a physical mechanism explaining this link is proposed, (2) A geostatistical epidemiological analysis links the disease with exposure to cooling towers, and (3) Climate and weather are ruled out as factors responsible for the long-term increase in case numbers (outside of seasonal trends).

Assistant Professor of Dermatology Johns Hopkins University School of Medicine MedicalResearch.com: What is the background for this study? Response: There has been a growing body of literature linking atopic dermatitis with diagnoses such as ADHD and learning disabilities, but studies focusing on symptoms of cognitive impairment (in contrast to relying on reported diagnoses as proxy measures of such) have been fewer and demonstrate inconsistent findings. Thus, we were interested in using data from this nationally representative sample of U.S. children to examine whether atopic dermatitis was associated with symptoms of learning or memory difficulties. Moreover, we wanted to examine how this relationship is influenced by known neurodevelopmental conditions to further characterize whether specific subgroups of children with atopic dermatitis are more susceptible to cognitive impairments.

Would you describe the IgG N-glycan profile? Response: Glycans are sugar coatings of proteins, made of monosaccharide building blocks, that are involved in a variety of biological pathways.  Different sugar structures can dictate or modify the protein’s activity through specific interactions with cellular receptors. For example, proteins lacking glycans have a reduced level or a complete loss of function. Glycans are of such importance that the 2022 Nobel Prize in chemistry was awarded for glycan-based science. In this study, we examined glycans attached to Immunoglobulins G (IgG) and their link with incidence of cardiovascular disease (CVD) due to their impact on IgG inflammatory properties. Since inflammation is not only a cause, but also an aggravating factor and a mediator of a worse prognosis in cardiometabolic disorders and CVD, we investigated whether different glycan structures may characterize an at-risk phenotype for CVD development. Determining glycan profiles involved in multiple conditions can serve prognostic and diagnostic purposes. Yet, unlike other types of macromolecules, glycans are still not as much explored, characterizing a promising but underappreciated class that should be further investigated.

How does this new AI model work?  How is it different from other models? Response: Modern multi-omic technologies generate an enormous amount of data across scales of organization, and with differing resolution. While recent machine learning methods have harnessed these to predict clinical/physiological outcomes, they are often black boxes that do not provide meaningful inference beyond prediction. Differences in data generation modalities, redundancy in the data, as well as large numbers of irrelevant features make inference of biological mechanisms from high-dimensional omic datasets challenging. To address these challenges, we developed a machine learning technique called SLIDE (Significant Latent Factor Interaction Discovery and Exploration). We reasoned that features that are directly measured by current technologies are constrained by strengths and weaknesses of current platforms. So, while some observed features may be excellent correlates of outcomes of interest, inferring biological mechanisms from these multi-omic datasets requires us to delve beyond the observable into the hidden states, i.e., latent factors. These hidden states encapsulate the true drivers of underlying biological processes and capture a complex multi-scale interplay between entities measured by these datasets. Our method moves beyond simple biomarkers/correlates (“the what”) to hidden states that actually explain clinical/physiological outcomes (“the how” and “the why”).

Genetic hearing loss mainly affects children. One in 600 newborns can have genetic hearing loss. There is no drug treatment for any type of hearing loss except for cochlear implants, which have limitations. This study focuses on a type of genetic hearing loss, DFNB9, due to a missing gene called Otoferlin. Without Otoferlin,  children are born with complete hearing loss and without the capacity to speak. The goal of the trial is to study if gene therapy is safe and efficacious in treating children so they can regain hearing and the ability to speak.

Response: It is now fairly well established that cannabis has a detrimental effect on driving. The most consistently reported effect of cannabis on driving is to increase ‘weaving’ on the road. We know that cannabis use is on the rise in people over 65 years of age. In fact, over the past few years cannabis use is increasing the most in this age group. Despite this, there are few studies of the effects of cannabis on people over 65; most studies have been conducted on younger adults. We know that there are important age-related changes in the way the body works that may alter the impact of cannabis on the body. Also, older adults may have more experience with cannabis and this can change the effects of cannabis.

MedicalResearch.com Interview with: [caption id="attachment_61263" align="alignleft" width="214"]John Sapp MD FRCPC FHRSHeart Rhythm, Division of Cardiology QEII Health Sciences Centre Dalhousie University Dr. Sapp[/caption] John Sapp MD FRCPC FHRSHeart Rhythm, Division of Cardiology QEII Health Sciences Centre Dalhousie University MedicalResearch.com: What is the background for this study? Response: Cardiac resynchronization is a robust therapy for heart failure in patients with ventricular dysfunction, left bundle branch block and left bundle branch block. It has been shown to improve heart failure status, symptoms, survival and reduce new onset ventricular arrhythmias for appropriate candidates. The RAFT study (NEJM 2010) enrolled patients with functional class II and III heart failure, wide QRS duration on ECG and reduced left ventricular ejection fraction, and demonstrated a reduction in heart failure hospitalization and mortality during a mean follow-up of 44 months. The long-term outcomes are not known.
Author Interviews, Immunotherapy, Kidney Disease, NEJM / 15.01.2024

MedicalResearch.com Interview with: VisterraMohit Mathur MD, FASN, FNKF, FRCP (Glasgow) Clinical fellow in Nephrology at UofT DM (Nephrology), MRCP.UK (SCE in Nephrology). Director, Clinical Development Visterra Waltham, MA 02451 MedicalResearch.com: What is the background for this study? Would you briefly describe the condition of IgA Nephropathy? Response: IgA Nephropathy is the commonest primary glomerular disease in the world. It is an autoimmune kidney disease that typically presents with urinary abnormalities, elevated blood pressure and reduced kidney function. Until recently IgAN was considered to be a benign disease, but recent studies have indicated that a majority of patients will progress to End stage kidney disease in their lifetime. Steroids have been the mainstay of treatment in IgAN, but they come at a very high burden of side effects. Thus, there is an urgent requirement to develop novel and safe treatment options for patients with IgAN. APRIL is considered to be a key cytokine implicated in the pathogenesis of IgAN, hence we decided to target APRIL as a therapeutic modality in IgAN.
