The Clinical Assessment of Eccentric and Concentric Stepping Kinetics has Utility in Older African American Men with Knee Arthritis.

Introduction: Stair navigation is physically demanding for individuals with knee osteoarthritis and may result in movement asymmetries that can be quantified using kinetic analysis and force-time parameters. Thus, the purpose of this cross-sectional study was to determine if kinetic force-time parameter asymmetries are present in individuals with knee osteoarthritis and associated with functional outcomes.

Methods: Forty-six older male veterans (61.

Placenta-derived SOD3 deletion impairs maternal behavior via alterations in FGF/FGFR-prolactin signaling axis.

Offspring growth requires establishing maternal behavior associated with the maternal endocrine profile. Placentae support the adaptations of the mother, producing bioactive molecules that affect maternal organs. We recently reported that placentae produce superoxide dismutase 3 (SOD3) that exerts sustained effects on the offspring liver via epigenetic modifications.

Advances in Multiple Sclerosis Neurotherapeutics, Neuroprotection, and Risk Mitigation Strategies.

The treatment of patients with relapsing multiple sclerosis (MS) has advanced tremendously over the past few decades. More efficacious therapies have been approved, which can significantly reduce the inflammatory process of relapsing MS. Neuroprotection by controlling this pathophysiology is important given our current limitations to control progressive MS and induce neurorepair.

A maternal higher-complex carbohydrate diet increases bifidobacteria and alters early life acquisition of the infant microbiome in women with gestational diabetes mellitus.

Gestational diabetes mellitus (GDM) is associated with considerable imbalances in intestinal microbiota that may underlie pathological conditions in both mothers and infants. To more definitively identify these alterations, we evaluated the maternal and infant gut microbiota through the shotgun metagenomic analysis of a subset of stool specimens collected from a randomized, controlled trial in diet-controlled women with GDM. The women were fed either a CHOICE diet (60% complex carbohydrate/25% fat/15% protein, n=18) or a conventional diet (CONV, 40% complex carbohydrate/45% fat/15% protein, n=16) from 30 weeks' gestation through delivery.

Pharmaceutical industry payments and assisted reproduction in Australia: a retrospective observational study.

Objectives: To investigate the extent and nature of pharmaceutical industry payments related to fertility and assisted reproduction in Australia.

Design And Setting: This retrospective observational study employed four databases compiled from publicly available pharmaceutical industry transparency reports on educational event sponsorship (October 2011-April 2018), payments to healthcare professionals (October 2015-April 2018) and patient group support (January 2013-December 2017). Analyses were restricted to fertility-related payments by two major manufacturers of fertility medicines in Australia: Merck Serono and Merck, Sharp and Dohme (MSD).

Coming face to face with implicit bias, microagressions, and macroaggressions: Understanding the influence of structural racism and misogyny on physician wellness.

Implicit bias, microaggressions, and macroaggressions have a negative impact on physician and trainee wellness. In this article, we describe how structural racism, misogyny, and other social constructs have shaped the medical landscape. Increasing awareness in medical education, patient care, and research can help to dismantle the effects.

Pulmonary Arterial Hypertension: Diagnosis, Treatment, and Novel Advances.

The diagnosis and management of pulmonary arterial hypertension (PAH) includes several advances, such as a broader recognition of extrapulmonary vascular organ system involvement, validated point-of-care clinical assessment tools, and focus on the early initiation of multiple pharmacotherapeutics in appropriate patients. Indeed, a principal goal in PAH today is an early diagnosis for prompt initiation of treatment to achieve a minimal symptom burden; optimize the patient's biochemical, hemodynamic, and functional profile; and limit adverse events. To accomplish this end, clinicians must be familiar with novel risk factors and the revised hemodynamic definition for PAH.

Global vascular surgeons' experience, stressors, and coping during the coronavirus disease 2019 pandemic.

Background: The coronavirus disease 2019 (COVID-19) pandemic has led to unprecedented challenges for health care systems globally. We designed and administered a global survey to examine the effects of COVID-19 on vascular surgeons and explore the COVID-19-related stressors faced, coping strategies used, and support structures available.

Methods: The Pandemic Practice, Anxiety, Coping, and Support Survey for Vascular Surgeons was an anonymous cross-sectional survey sponsored by the Society for Vascular Surgery Wellness Task Force.

Early Pulmonary Vascular Disease in Preterm Infants Is Associated with Late Respiratory Outcomes in Childhood.

Rationale: Early pulmonary vascular disease (PVD) after preterm birth is associated with a high risk for developing bronchopulmonary dysplasia (BPD), but its relationship with late respiratory outcomes during early childhood remains uncertain.

Objectives: To determine whether PVD at 7 days after preterm birth is associated with late respiratory disease (LRD) during early childhood.

Methods: This was a prospective study of preterm infants born before 34 weeks postmenstrual age (PMA).

Challenges to Reshape the Future of Type 1 Diabetes Research.

Context: Immunotherapy trials to prevent type 1 diabetes have been unsuccessful for >15 years. Understanding pitfalls and knowledge gaps in the immunology of type 1 diabetes should lead us in new directions that will yield better trial outcomes. A proposal is made for precision medicine trial design in future type 1 diabetes studies.
