Barry, M.D Director of the Informed Medical Decisions Program Health Decision Sciences Center Massachusetts General Hospital. Professor of medicine at Harvard Medical School Dr. Barry was appointed as Vice Chair of USPSTF in March 2021. He previously served as a member from January 2017 through December 2020.   MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: The Task Force looked at the use of vitamin and mineral supplementation specifically for the prevention of heart disease, stroke, and cancer. We found that there is not enough evidence to recommend for or against taking multivitamin supplements, nor the use of single or paired nutrient supplements, to prevent these conditions. However, we do know that you should not take vitamin E or beta-carotene for this purpose.

We wanted to quantify the effect of the “pause” on cancer stage at diagnosis using lung cancer as an example of a condition where early diagnosis can dramatically modify survival.
Author Interviews, Brigham & Women's - Harvard, Neurology, Parkinson's / 21.06.2022

MedicalResearch.com Interview with: [caption id="attachment_59275" align="alignleft" width="180"]Vikram Khurana, MD, PhD Chief of the Division of Movement Disorders Department of Neurology Brigham and Harvard Medical School Principal investigator, Ann Romney Center for Neurologic Diseases at the Brigham Dr. Khurana[/caption] Vikram Khurana, MD, PhD Chief of the Division of Movement Disorders Department of Neurology Brigham and Harvard Medical School Principal investigator, Ann Romney Center for Neurologic Diseases at the Brigham MedicalResearch.com:  What is the background for this study?   Response: Proteins abnormally accumulate in brain cells (neurons and glial cells) in all neurodegenerative diseases. In Parkinson’s disease and related disorders, the key protein that accumulates and aggregates is called “alpha-synuclein.” Presumably, when a protein like alpha-synuclein abnormally folds and aggregates, the abnormal form of the protein can become toxic to the neuron, eventually leading to cell death. Equally, the protein may no longer be able to carry out its normal function. This begs the question – what does alpha synuclein actually do? Most evidence to date points to alpha-synuclein being involved in the transport of other proteins and chemicals around the cell, by closely associating with vesicles that are small circular containers enclosed by fat (“lipid) membranes. But alpha-synuclein is not just found associated with these vesicle membrane. It is found away from the membrane and it’s been unclear what it does there.

The level of protection provided by prior infection or vaccination with Pfizer and Moderna mRNA vaccines or a combination of both against infection with Omicron BA.1 and BA.2 subvariants was unknown.
Author Interviews, Critical Care - Intensive Care - ICUs, NEJM, Vitamin C / 15.06.2022

MedicalResearch.com Interview with: François Lamontagne MD MSc (pharmacology) MSc (CEB) Professor of Medicine at the Université de Sherbrooke Endowed research chair on patient-centred research Dr. Neill Adhikari MDCM, M.Sc. Sunnybrook Research Institute and University of Toronto Toronto, Canada MedicalResearch.com:  What is the background for this study?  Response: The use of intravenous vitamin C for sepsis has been a hot topic for a few years. It was biologically plausible that vitamin C could reduce organ injury and death by scavenging reactive oxygen species and modulating the immune response to sepsis. It also seemed like an intervention that would be reasonably easy to administer globally should it prove beneficial. On the other hand, no intervention is benign and every aspect of health care should be rigorously studied. Regarding vitamin C, there were strongly held opinions in both camps and this motivated us to design and conduct the LOVIT trial.

Lurie Comprehensive Cancer Center Feinberg School of Medicine, Northwestern University MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response: Incidence, mortality, and survivorship provide a comprehensive description of cancer for a group of people. Differences in cancer incidence and mortality trends by rural-urban status and race and ethnicity are well documented, but urban-rural cancer survivorship trends by race and ethnicity are unknown. To this end, we examined almost 40 years of racial and ethnic differences by rural-urban status for 5-year survival of patients with lung, prostate, breast, and colorectal cancers. Using a nationwide epidemiological assessment of 1975-2011 data from the SEER database, we found that 5-year cancer-specific survival trends increased for all cancer types and race and ethnic groups, regardless of rural or urban status. Generally, rural, and non-Hispanic Black cancer patients had worse survival outcomes than others.

Rome MD Instructor, Harvard Medical School Internal Medicine Division of Pharmacoepidemiology and Pharmacoeconomics Brigham and Women’s Hospital Dr. Rome[/caption] Benjamin N. Rome MD Instructor, Harvard Medical School Internal Medicine Division of Pharmacoepidemiology and Pharmacoeconomics Brigham and Women’s Hospital MedicalResearch.com:  What is the background for this study? What are the main findings?  Response: Manufacturers of brand-name drugs are granted periods, free from direct competition, during which they can set and raise prices as they choose. We found that the prices for newly marketed brand-name drugs increased by 20% per year from 2008 to 2021. In 2020 and 2021, nearly half of new drugs were launched at a price greater than $150,000 per year, compared with 9% of drugs in 2008-2013. These dramatic trends are only partly explained by changes in the types of drugs coming to market.

Author Interviews, Brain Injury, NEJM / 09.06.2022

MedicalResearch.com Interview with: Daniel Perl MD Uniformed Services University of the Health Sciences Professor of Pathology at USUHS and Director of the CNRM's Brain Tissue Repository Uniformed Services University of the Health Sciences Bethesda, Maryland MedicalResearch.com:  What is the background for this study?  Response: Chronic traumatic encephalopathy (CTE) is a brain disorder that is predominantly seen in individuals who have suffered from repeated impact head trauma, such as occurs in former boxers or American football players.  CTE has very specific alterations in the brain and can only be diagnosed at autopsy.  Some have claimed that, in addition to former contact sport participants, individuals who served in the military and were repeatedly exposed to blast (explosions) are also at increased risk for developing CTE.  However, this claim has been based on a rather small number of anecdotal cases.  The DoD/USU Brain Tissue Repository is the only facility in the world that is exclusively dedicated to the collection and study of donated brain specimens derived from deceased active duty and retired service members.  We used the resources of this facility to examine 225 consecutively collected brain specimens for the presence of CTE.  This would to provide a view of how common CTE was in this setting and, when diagnosed, was the disease correlated with prior blast exposure, participation in contact sports and other forms of head trauma, and with certain forms of symptomatology such as development of PTSD, alcohol/substance abuse, death by suicide, etc.

MedicalResearch.com Interview with: Katherine Garcia MD NYU Langone Health MedicalResearch.com:  What is the background for this study?  Response: Studies on cancer patients during the COVID-19 pandemic have shown a decrease in new diagnoses, delays in care, and a shift to later stage disease presentations. Considering that NY has been an epicenter for COVID-19 in the U.S., we investigated its impact on new cancer diagnoses at the two campuses of NYU’s Perlmutter Cancer Center and hypothesized that there would be a decrease in presentations during the peak outbreaks in NY.

(Hiddo) Lambers Heerspink Clinical Pharmacologist Department Clinical Pharmacy and Pharmacology University Medical Center Groningen Groningen  MedicalResearch.com:  What is the background for this study?    Response: Tirzepatide is a novel GIP-GLP1 receptor agonist recently FDA approved for the treatment of type 2 diabetes. The SURPASS_4 trial demonstrated that in patients with type 2 diabetes at high cardiovascular risk tirzepatide compared to insulin glargine markedly reduces Hba1c and body weight. About 1 out of 3 patients with type 2 diabetes and CV disease has kidney disease and these patients are at high risk of kidney failure. The aim of this study was to assess whether tirzepatide could slow CKD progression in high risk individuals with type 2 diabetes participating in the SURPASS 4 trial. 
Addiction, Author Interviews, Opiods / 07.06.2022

MedicalResearch.com Interview with: [caption id="attachment_59228" align="alignleft" width="125"]Colleen G. Jordan, MBS Department of Medical Education Geisinger Commonwealth School of Medicine Colleen Jordan[/caption] Colleen G. Jordan, MBS Department of Medical Education Geisinger Commonwealth School of Medicine MedicalResearch.com: What is the background for this study? Response: Opioid addiction and misuse remain a prevalent issue in the United States (U.S.). There have been more than one-million drug overdoses in the U.S. since 1999 [1], largely driven by opioids, which exacerbate the strain on resources in hospitals, treatment centers, first responders, patients, and their families. The existing pharmacotherapies for opioid use disorder (OUD) are not working. Naloxone is a competitive mu opioid receptor antagonist used to reverse respiratory and CNS depression in those experiencing an opioid overdose but requires further dosing to prevent subsequent overdose. Naltrexone is a competitive mu opioid receptor antagonist, and has extended-release formulations intended to reduce relapse and promote adherence, yet patient noncompliance and retention continue to be limiting factors. Methadone is commonly used to treat opioid addiction as a replacement for illicit opiates but is itself an addictive substance which can result in overdoses [2] and can lead to withdrawal if not closely monitored by a licensed professional. Buprenorphine is currently used to treat opioid use disorder (OUD), and while it reduces illicit drug use, it is less effective than methadone for retaining patients in treatment. For these reasons, there is an urgent need for new opioid misuse interventions. The objectives of this study [3] were to understand the implications of OUD and overdose treatments and determine the strengths and shortcomings of current treatments in comparison with the novel drug candidate methocinnamox (MCAM). These were completed through an extensive literature review into the history of the opioid epidemic in the United States, opioid receptors in the brain, current pharmacological treatments, and the pharmacological properties of MCAM.

As a result, we wanted to better understand if symptoms among the autoimmune and rheumatic disease patients in our ArthritisPower research registry were impacted throughout the COVID-19 pandemic. We previously conducted and reported on an analysis of patient reported outcome data from the ArthritisPower registry between the months of January 2020 to April 2021 at the American College of Rheumatology Convergence in 2021. We conducted a follow-up analysis between May and December 2021, which is our area of focus in this particular abstract.
Annals Internal Medicine, Author Interviews, Brigham & Women's - Harvard, Diabetes, Heart Disease / 07.06.2022

MedicalResearch.com Interview with: [caption id="attachment_59221" align="alignleft" width="150"]HoJin Shin, BPharm, PhD Postdoctoral Research Fellow Division of Pharmacoepidemiology and Pharmacoeconomics Department of Medicine Brigham and Women's Hospital and Harvard Medical School Boston, Massachusetts Dr. HoJin Shin[/caption] HoJin Shin, BPharm, PhD Postdoctoral Research Fellow Division of Pharmacoepidemiology and Pharmacoeconomics Department of Medicine Brigham and Women's Hospital and Harvard Medical School Boston, Massachusetts MedicalResearch.com:  What is the background for this study?  Response: The public health burden of cardiovascular disease has been increasing in people with diabetes along with the burden of diabetes itself.
  •  Cardiovascular disease affects approximately one-third of the population with type 2 diabetes and accounts for     50%–80% of their mortality
  • 1 in 10 people in the US has diabetes
Since 2008, the US FDA has recommended post-approval cardiovascular outcome trials to ensure the safety of new glucose-lowering drugs responding to this growing burden of cardiovascular disease in type 2 diabetes and the potential increase in cardiovascular risk with certain existing glucose-lowering drugs (e.g., rosiglitazone). Notably, SGLT-2i have demonstrated superiority to placebo in reducing the risk of cardiovascular events, including hospitalization for heart failure. Consequently, beginning in 2018, clinical guidelines in the US have recommended SGLT-2i as a preferred second-line treatment for patients with type 2 diabetes and cardiovascular disease. As the paradigm of second-line pharmacological treatment for type 2 diabetes has shifted to include the management of cardiovascular risk in addition to glycemic control, this further raised the question of whether SGLT-2i should be advanced to first-line treatment. Since 2019, SGLT-2i have been recommended as a first-line agent for patients with type 2 diabetes and cardiovascular disease by the European guidelines (the European Society of Cardiology and the European Association for the Study of Diabetes). In the absence of head-to-head RCTs, non-randomized studies using real-world data could provide information on whether SGLT-2i may have greater cardiovascular benefits over metformin more timely than randomized clinical trials among both patients with and without existing CVD. Therefore, we evaluated the risk for cardiovascular events among adults with T2D who initiated treatment with first-line SGLT-2i versus metformin in clinical practice.

Despite this, earlier clinical trials have failed to prove a beneficial impact on kidney disease progression from uric acid lowering therapy in patients with preexisting CKD. The effect of uric acid lowering therapy on the development of new onset CKD in patients with normal kidney function has not been well studied. In our large observational study we did not find a beneficial association between newly initiated uric acid lowering therapy (the majority of which was in the form of allopurinol). On the contrary, uric acid lowering therapy was associated with a slightly higher risk of new onset low eGFR and new onset albuminuria, especially in patients with less elevated baseline serum acid levels.

MedicalResearch.com Interview with: [caption id="attachment_59198" align="alignleft" width="200"]Imad Shureiqi, MD, MS Professor, Division of Hematology and Oncology Department of Internal Medicine  Rogel Cancer Center Ann Arbor, MI, 48109 Prof. Shureiqi[/caption] Imad Shureiqi, MD, MS Professor, Division of Hematology and Oncology Department of Internal Medicine Rogel Cancer Center Ann Arbor, MI, 48109 MedicalResearch.com:  What is the background for this study?   Response: Pancreatic ductal adenocarcinoma is a highly lethal form of cancer with rising occurrence, and strategies to prevent and treat the disease are urgently needed. Most cases of pancreatic cancer arise from pre-cancerous lesions called pancreatic intraepithelial neoplasia (PanIN); about 55-80% of adults over forty are estimated to have these low-grade pre-cancerous silent pancreatic lesions. But critical factors that promote the progression of pancreatic pre-cancerous lesions to pancreatic cancer remain poorly defined, especially those easy to target. Findings from this publication indicate that people who have silent PanIN pre-cancerous lesions, even those that are low-grade, could increase their risk of PanIN progression into pancreatic cancer by consuming activators of a nuclear lipid receptor called peroxisome proliferator-activated receptor-delta (PPARδ). PPARδ activators can be natural substances, such certain fatty acids like palmitic and arachidonic acid in high-fat diets, or synthetic ones, like Cardarine (GW501516).

MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response: Impaired vision and glaucoma are serious and common conditions facing millions of people nationwide that can affect a person’s independence and quality of life. These recommendations looked at how primary care clinicians can help people who have not noticed any problems with their vision. Unfortunately, there is not enough evidence available to make a recommendation for or against screening adults for glaucoma or older adults for impaired vision in the primary care setting.

MedicalResearch.com Interview with: Kathryn S. Smith, BS M.D. Candidate, Class of 2023 Northwestern University Feinberg School of Medicine Chicago, Illinois MedicalResearch.com:  What is the background for this study  Response: There are studies that show women in medicine do not achieve promotion at the same rate as men and that only a minority of women are in the upper levels of leadership such as Department Chairs and Medical School Deans. Since peak fertility coincides with peak career building years, we wanted to explore themes related to career advancement, physician burnout and ultimately whether women were being held back from their potential by the burden of fertility, family building, childcare, and household responsibilities.
Author Interviews, BMJ, Brigham & Women's - Harvard, Education, Health Care Systems, Sleep Disorders / 20.05.2022

MedicalResearch.com Interview with: [caption id="attachment_59185" align="alignleft" width="150"] Dr. Weaver[/caption] Dr Matthew D Weaver M.P.H., Ph.D. Division of Sleep and Circadian Disorders Departments of Medicine and Neurology Brigham and Women's Hospital Boston, Massachusetts MedicalResearch.com:  What is the background for this study?  Response: The name “resident” stems from the historical practice of resident-physicians residing in hospitals as part of their training. Even after that practice abated, it was common for resident physicians to work 36 consecutive hours followed by 12 or fewer hours of rest. In 1989, the state of New York restricted resident physicians to work no more than 24 consecutive hours and no more than 80 hours per week as part of collective intervention to improve patient safety. The Accreditation Council for Graduate Medical Education (ACGME) then followed in 2003 by limiting work hours to an average of 80 per week over a month and no more than 30 consecutive hours of work. Evidence accumulated demonstrating an association between shifts lasting ≥24 hours and adverse resident and patient safety. As a result, the Institute of Medicine convened a review and report on the issue, ultimately concluding that no resident should work more than 16 consecutive hours without sleep. This recommendation, combined with evidence following the 2003 rules, led the ACGME to issue new rules in 2011 that limited first-year resident physicians to work no more than 16 consecutive hours. Our study compares resident-reported patient safety outcomes before and after this 2011 policy change.

Response: Barrett’s esophagus (BE), is a premalignant condition that can lead to esophageal cancer (called esophageal adenocarcinoma). Both diseases have historically been thought of as diseases of elderly white males. While both diseases have been on the rise in the elderly population, we noted that some cancers are becoming more common at younger ages. We wanted to see if the prevalence of BE and EC are increasing at younger ages.  We aimed to assess the prevalence of BE in and EAC based on age group in a large database of over 5 million patients.

MedicalResearch.com Interview with: [caption id="attachment_59179" align="alignleft" width="150"]Robert Wild, Ph.D Chief Scientific Officer Dracen Pharmaceuticals Dr. Wild[/caption] Robert Wild, Ph.D Chief Scientific Officer Dracen Pharmaceuticals   MedicalResearch.com:  What is the background for the development of sirpiglenastat, i.e., would you briefly explain what is meant by glutamine antagonist? Response: Cancer cells consume and use glutamine for both energy generation and as a source of carbon and nitrogen for biomass accumulation. Many oncogenes and tumor suppressor genes drive large-scale metabolic reprogramming of tumors into glutamine addiction. These highly proliferating tumors create a hostile and immunosuppressive tumor microenvironment (TME), which is nutrient- depleted, acidic and hypoxic in nature. Sirpiglenastat (DRP-104), is a novel broad-acting glutamine antagonist that inhibits all 10 known glutamine metabolism enzymes. DRP-104 was designed to preferentially inhibit glutamine metabolism in tumors and associated TME and not in normal tissues, providing a large therapeutic window. DRP-104 demonstrates powerful direct apoptotic (cell death) properties and immune modulatory mechanisms through broad remodeling of the TME to infer DRP-104 impacts immune-metabolism. Inhibition of glutamine metabolism leads to:
  • Induction of apoptosis in glutamine-addicted tumor cells leading to substantial single-agent activity and tumor regressions
  • Rebalance of the TME that enhances immune cell infiltration and function
  • Differentiation and modulation of adaptive and innate immune cells toward a highly proliferative, activated and long-lived phenotype for a long-term durable response.

NAFLD is a multisystem diseases that associated with cardiovascular diseases, metabolic diseases (diabetes, hypertension, and dyslipidemia), or chronic kidney disease. Whether lean persons with NAFLD have lower prevalence of cirrhosis, CVD, CKD than non-lean persons with NAFLD remains inconclusive.

Simmons Comprehensive Cancer Center Professor of Internal Medicine Division of Digestive and Liver Diseases, Department of Internal Medicine University of Texas Southwestern Medical Center MedicalResearch.com:  What is the background for this study?  Response: Liver cancer is the fastest rising cause of cancer-related death in the U.S. with the sharply growing epidemic of obesity and non-alcoholic fatty liver disease. Late diagnosis at advanced stage is the main reason for the poor survival of liver cancer patients. Therefore, professional societies recommend semi-annual liver cancer screening for early diagnosis. However, it's practically infeasible due to the vast size of patient population (estimated to affect one-fourth of population). Thus, we urgently need tools to identify a small subset of patients with elevated liver cancer risk, on which we can concentrate our effort of screening.

Older age, higher body mass index, and receipt of chemotherapy treatment that can injure the heart are risk factors for cardiovascular death after a breast cancer diagnosis. Time-restricted eating is a type of intermittent fasting that appears to be easy to follow and to improve some measures of metabolic health but has not been studied in populations with a cancer history. Time-restricted eating simply involves consuming all calorie intake within a specific time window, commonly 8 hours, like between 12 and 8 pm, and then only consuming water or black coffee outside of those hours. We enrolled breast cancer survivors who were aged 60 or older, had an overweight or obese mass index, and were finished chemotherapy treatment in a single-arm trial of time-restricted eating for 8 weeks. We asked participants to restrict their calorie intake between 12 and 8 pm from Monday to Friday with no restrictions on weekend and no further instructions on what to eat.

It has been argued that prior estimates of statin effects were mainly based on information from both individuals with and without pre-existing cardiovascular disease, which may overestimate the true benefits of statins. Some investigators attempted to quantify the impact of statins on outcomes of women versus men and reported significantly different effect estimates. Others have questioned the benefits of statins in adults 76 years and older as this age group was poorly represented in the randomized trials for primary prevention of cardiovascular disease. There is little or no information on concomitant preventive medications in prior work. Thus, how large is the incremental benefit of statin, added to other standard preventive interventions? and is cholesterol a reliable surrogate endpoint to guide prevention of cardiovascular disease?
