Trends in Percutaneous Balloon Mitral Valvuloplasty Complications for Mitral Stenosis in the United States (the National Inpatient Sample [2008 to 2018]).

The epidemiology of mitral stenosis (MS) continues to evolve in the United States. Although the incidence of rheumatic MS has decreased in high-income countries, there is a paucity of data surrounding trends in percutaneous balloon mitral valvuloplasty (PBMV), the current first-line management strategy. This study aimed to identify contemporary trends in PBMV in the United States.

Using Telemedicine to Assess and Manage Psychosis in Neurodegenerative Diseases in Long-Term Care.

The coronavirus disease 2019 (COVID-19) epidemic has forced a sudden global implementation of telemedicine strategies, including in long-term care (LTC) facilities where many people with dementia and Parkinson disease (PD) reside. Telemedicine offers a unique set of advantages for residents in LTC facilities if effectively supported and implemented, including expanded access to specialists in rural or underserved areas or for people with dementia who cannot travel for off-site visits. Many medical and psychiatric organizations have recently issued new or updated guidelines on the use of telemedicine.

Innovations in vascular access for hemodialysis.

Worldwide, hemodialysis remains the prevalent dialysis modality for more than 2 million patients who require well-functioning vascular access for this procedure. Creation of an arteriovenous fistula for long-term hemodialysis was the first innovation since the Scribner shunt and was followed by the development of an arteriovenous graft and catheter. Bioengineered vessels were developed during the last century, but this field has been energized by recent technology relating to the creation of human vessels.

Challenges and solutions in the design and execution of the PROSPECT Phase II/III neoadjuvant rectal cancer trial (NCCTG N1048/Alliance).

Background: More than half of the 40,000 incident rectal cancer patients in the United States each year are diagnosed at clinical stage II and III (locally advanced stage). For this group, high rates of cure can be achieved with the combination of pelvic radiation and sensitizing 5-fluorouracil (chemoradiation), surgery and chemotherapy, but treatment is long, arduous and toxicities are substantial. The PROSPECT trial (N1048, NCT01515787) was designed to determine whether neoadjuvant chemotherapy with 5-fluorouracil and oxaliplatin (FOLFOX) could be used as an alternative to neoadjuvant chemoradiation without compromising treatment outcomes and to spare these patients excess toxicity.

A Call to Action to Address Gender Equity Within Our Specialty: Time's Up on Waiting for Change.

Although national attention has been focused on sexual harassment and gender inequity in the United States, leaders within the obstetrics and gynecology community have remained relatively silent. Sexual harassment and gender inequity remain pervasive in our specialty. This article serves as a call to action for leadership as well as physicians within obstetrics and gynecology to implement ethical and evidence-based approaches to reduce gender inequity and improve workplace culture within our specialty.

Liraglutide and Renal Outcomes in Type 2 Diabetes.

Background: In a randomized, controlled trial that compared liraglutide, a glucagon-like peptide 1 analogue, with placebo in patients with type 2 diabetes and high cardiovascular risk who were receiving usual care, we found that liraglutide resulted in lower risks of the primary end point (nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes) and death. However, the long-term effects of liraglutide on renal outcomes in patients with type 2 diabetes are unknown.

Methods: We report the prespecified secondary renal outcomes of that randomized, controlled trial in which patients were assigned to receive liraglutide or placebo.

Efficacy and Safety of Degludec versus Glargine in Type 2 Diabetes.

Background: Degludec is an ultralong-acting, once-daily basal insulin that is approved for use in adults, adolescents, and children with diabetes. Previous open-label studies have shown lower day-to-day variability in the glucose-lowering effect and lower rates of hypoglycemia among patients who received degludec than among those who received basal insulin glargine. However, data are lacking on the cardiovascular safety of degludec.

Management of Closed Diaphyseal Humerus Fractures in Patients With Injury Severity Score ≥17.

Objectives: The management of closed diaphyseal humerus fractures in the polytrauma patient varies widely. The aim of this study was to compare outcomes of operative and nonoperative management in this patient population.

Design: Single-center, retrospective cohort analysis.

Management of Acute and Recurrent Gout: A Clinical Practice Guideline From the American College of Physicians.

Description: The American College of Physicians (ACP) developed this guideline to present the evidence and provide clinical recommendations on the management of gout.

Methods: Using the ACP grading system, the committee based these recommendations on a systematic review of randomized, controlled trials; systematic reviews; and large observational studies published between January 2010 and March 2016. Clinical outcomes evaluated included pain, joint swelling and tenderness, activities of daily living, patient global assessment, recurrence, intermediate outcomes of serum urate levels, and harms.

Predicting urban design effects on physical activity and public health: A case study.

With increasing global concerns about obesity and related health effects, tools to predict how urban form affects population physical activity and health are needed. However, such tools have not been well established. This article develops a computer simulation model for forecasting the health effects of urban features that promote walking.

Effect of Sitagliptin on Cardiovascular Outcomes in Type 2 Diabetes.

Background: Data are lacking on the long-term effect on cardiovascular events of adding sitagliptin, a dipeptidyl peptidase 4 inhibitor, to usual care in patients with type 2 diabetes and cardiovascular disease.

Methods: In this randomized, double-blind study, we assigned 14,671 patients to add either sitagliptin or placebo to their existing therapy. Open-label use of antihyperglycemic therapy was encouraged as required, aimed at reaching individually appropriate glycemic targets in all patients.

Safety, pharmacokinetic, and functional effects of the nogo-a monoclonal antibody in amyotrophic lateral sclerosis: a randomized, first-in-human clinical trial.

Unlabelled: The neurite outgrowth inhibitor, Nogo-A, has been shown to be overexpressed in skeletal muscle in amyotrophic lateral sclerosis (ALS); it is both a potential biomarker and therapeutic target. We performed a double-blind, two-part, dose-escalation study, in subjects with ALS, assessing safety, pharmacokinetics (PK) and functional effects of ozanezumab, a humanized monoclonal antibody against Nogo-A. In Part 1, 40 subjects were randomized (3∶1) to receive single dose intravenous ozanezumab (0.

The National Partnership for Maternal Safety.

Recognition of the need to reduce maternal mortality and morbidity in the United States has led to the creation of the National Partnership for Maternal Safety. This collaborative, broad-based initiative will begin with three priority bundles for the most common preventable causes of maternal death and severe morbidity: obstetric hemorrhage, severe hypertension in pregnancy, and peripartum venous thromboembolism. In addition, three unit-improvement bundles for obstetric services were identified: a structured approach for the recognition of early warning signs and symptoms, structured internal case reviews to identify systems improvement opportunities, and support tools for patients, families, and staff that experience an adverse outcome.

Shadows amid sunshine: regulating financial conflicts in medical research.

Under brand new rules implementing the Physician Payments Sunshine Act (Sunshine Act), a wide range of financial relationships, including many research-related payments, between industry, physicians, and teaching hospitals will be publicly disclosed through comprehensive, standardized payment reporting. The Sunshine Act represents the latest in a series of regulatory attempts to address financial conflicts of interest that may bias research conduct and threaten subject safety. This article summarizes the major aspects of the Sunshine Act affecting medical research, how it interacts with existing laws and policies, and identifies important unresolved issues and implementation challenges that still lie ahead with the rollout of the legislation underway.

Structural and evolutionary division of phosphotyrosine binding (PTB) domains.

Proteins encoding phosphotyrosine binding (PTB) domains function as adaptors or scaffolds to organize the signaling complexes involved in wide-ranging physiological processes including neural development, immunity, tissue homeostasis and cell growth. There are more than 200 proteins in eukaryotes and nearly 60 human proteins having PTB domains. Six PTB domain encoded proteins have been found to have mutations that contribute to inherited human diseases including familial stroke, hypercholesteremia, coronary artery disease, Alzheimer's disease and diabetes, demonstrating the importance of PTB scaffold proteins in organizing critical signaling complexes.
