Anti-inflammatory Therapeutics and Coronary Artery Disease.

It has been demonstrated that atherosclerotic disease progression is contingent upon chronic inflammation. The sequence of events leading up to plaque formation, instability, and eventual plaque rupture hinges upon the interaction of proinflammatory cytokines and fat deposition within the coronary vasculature. Over the past decade, a large body of evidence has demonstrated the efficacy of specific anti-inflammatory therapeutics in halting the progression of coronary artery disease.

Ancestral diversity improves discovery and fine-mapping of genetic loci for anthropometric traits-The Hispanic/Latino Anthropometry Consortium.

Hispanic/Latinos have been underrepresented in genome-wide association studies (GWAS) for anthropometric traits despite their notable anthropometric variability, ancestry proportions, and high burden of growth stunting and overweight/obesity. To address this knowledge gap, we analyzed densely imputed genetic data in a sample of Hispanic/Latino adults to identify and fine-map genetic variants associated with body mass index (BMI), height, and BMI-adjusted waist-to-hip ratio (WHRadjBMI). We conducted a GWAS of 18 studies/consortia as part of the Hispanic/Latino Anthropometry (HISLA) Consortium (stage 1, n = 59,771) and generalized our findings in 9 additional studies (stage 2, n = 10,538).

Monogenic and Polygenic Contributions to QTc Prolongation in the Population.

Background: Rare sequence variation in genes underlying cardiac repolarization and common polygenic variation influence QT interval duration. However, current clinical genetic testing of individuals with unexplained QT prolongation is restricted to examination of monogenic rare variants. The recent emergence of large-scale biorepositories with sequence data enables examination of the joint contribution of rare and common variations to the QT interval in the population.

Association of HIV Serostatus and Inflammation With Ascending Aortic Size.

Background The prevalence and extent of subclinical large vessel vasculopathy is not well defined among people living with HIV. We aimed to evaluate associations between aortic root and ascending aortic sizes measured by 2-dimensional transthoracic echocardiography and HIV serostatus, and to identify risk factors for larger aortic sizes among men with HIV, including levels of circulating inflammatory markers. Methods and Results Using clinical and echocardiographic data from the MACS (Multicenter AIDS Cohort Study), adjusted multivariable linear and logistic regression was performed.

Patient Selection and Planning for Image-Guided Peritoneal Dialysis Catheter Placement.

Image-guided percutaneous peritoneal dialysis (PD) catheter insertion has become increasingly relied upon to provide urgent access for late presenting kidney failure patients, to overcome surgical backlogs and limited operating room access, to avoid general anesthesia in high-risk patients, and, by itself, as an alternative approach to surgical PD access. Advanced planning for the procedure is essential to assure the best possible outcome. Appropriate selection of patients for percutaneous PD catheter placement, choosing the most suitable catheter type, determining insertion and exit site locations, and final patient preparations facilitate the performance of the procedure, minimizes the risk of complications, and improves the likelihood of providing a successful long-term peritoneal access.

A Case of Native Joint Septic Arthritis Caused by Bacteroides fragilis.

BACKGROUND Bacteroides fragilis (B. fragilis) is an uncommon cause of native joint septic arthritis (NJSA). It is an anaerobic gram-negative rod that is normally found in the oral cavity, gastrointestinal tract, genitourinary system, and skin, and thus is rarely isolated from the musculoskeletal system.

Diabetic Retinopathy and Insulin Insufficiency: Beta Cell Replacement as a Strategy to Prevent Blindness.

Diabetic retinopathy (DR) is a potentially devastating complication of diabetes because it puts patients at risk of blindness. Diabetes is a common cause of blindness in the U.S.

Students Teaching Students: Student-Led Ultrasound Curriculum in Medical School Education.

Introduction With the expanding use of point-of-care ultrasound throughout medical specialties for the rapid bedside assessment integral to patient care, medical schools have sought to incorporate ultrasound education into their curriculum. Second-year medical students (MS2s) at our institution met this demand by forming the Ultrasound Student Instructor Cadre (USSIC), a longitudinal ultrasound curriculum where MS2s teach first-year medical students (MS1s). The objectives of this study were to assess the ultrasound knowledge of medical students and their perceptions of ultrasound incorporation into their medical education.

Aggressive Afterload Lowering to Improve the Right Ventricle: A New Target for Medical Therapy in Pulmonary Arterial Hypertension?

Despite numerous therapeutic advances in pulmonary arterial hypertension, patients continue to suffer high morbidity and mortality, particularly considering a median age of 50 years. This article explores whether early, robust reduction of right ventricular afterload would facilitate substantial improvement in right ventricular function and thus whether afterload reduction should be a treatment goal for pulmonary arterial hypertension. The earliest clinical studies of prostanoid treatment in pulmonary arterial hypertension demonstrated an important link between lowering mean pulmonary arterial pressure (or pulmonary vascular resistance) and improved survival.

Association of clonal hematopoiesis with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is associated with age and smoking, but other determinants of the disease are incompletely understood. Clonal hematopoiesis of indeterminate potential (CHIP) is a common, age-related state in which somatic mutations in clonal blood populations induce aberrant inflammatory responses. Patients with CHIP have an elevated risk for cardiovascular disease, but the association of CHIP with COPD remains unclear.

Ultrasound-Guided Stellate Ganglion Block With Preserved Motor Function for Upper Extremity Surgery.

While stellate ganglion blockade (SGB) is commonly used in the treatment and management of patients who suffer from chronic pain, we are reporting a case where an ultrasound-guided SGB was used for management of acute perioperative pain for a patient undergoing upper extremity surgery. The patient was classified as the American Society of Anesthesiologists (ASA) class 1, without any significant past medical history, including no history of chronic pain, opioid use, or peripheral neuropathy. The patient was scheduled for tendon repair of the hand following trauma with subsequent lacerations.

Outcomes of obese patients hospitalized with COVID-19: the impact of prior bariatric surgery.

Background: Obesity and several obesity-related co-morbidities are risk factors for severe COVID-19 disease. Because bariatric surgery successfully treats obesity-related conditions, we hypothesized that prior bariatric surgery may be associated with less severe COVID-19 disease.

Objectives: To examine the association between prior bariatric surgery and outcomes in patients with obesity admitted with COVID-19.

Organ donor management goals and delayed graft function in adult kidney transplant recipients.

Background: Delayed graft function (DGF) after kidney transplantation is a common occurrence and correlates with poor graft and patient outcomes. Donor characteristics and care are known to impact DGF. We attempted to show the relationship between achievement of specific donor management goals (DMG) and DGF.

Systematic Review of Serum Biomarkers in Traumatic Brain Injury.

Traumatic brain injury (TBI) is responsible for the majority of trauma-related deaths and is a leading cause of disability. It is characterized by an inflammatory process involved in the progression of secondary brain injury. TBI is measured by the Glasgow Coma Scale (GCS) with scores ranging from 15-3, demonstrating mild to severe brain injury.

Association between human immunodeficiency virus serostatus and the prevalence of atrial fibrillation.

Atrial fibrillation (AF) leads to increased risk for stroke. Human immunodeficiency virus (HIV) is associated with cardiovascular disease (CVD), although it is unclear if HIV is associated with AF. The purpose of this study was to evaluate the association between HIV serostatus and the prevalence of AF in the Multicenter AIDS Cohort Study.

Combination treatment of liposomal amphotericin B and isavuconazole is synergistic in treating experimental mucormycosis.

Objectives: Liposomal amphotericin B (L-AMB) and isavuconazonium sulphate are commonly used antifungal drugs to treat mucormycosis. However, the efficacy of combination therapy of L-AMB/isavuconazonium sulphate versus monotherapy is unknown. We used an immunosuppressed mouse model of pulmonary mucormycosis to compare the efficacy of L-AMB/isavuconazonium sulphate versus either drug alone.

Adipose tissue biomarkers and type 2 diabetes incidence in normoglycemic participants in the MESArthritis Ancillary Study: A cohort study.

Background: Given the central role of skeletal muscles in glucose homeostasis, deposition of adipose depots beneath the fascia of muscles (versus subcutaneous adipose tissue [SAT]) may precede insulin resistance and type 2 diabetes (T2D) incidence. This study was aimed to investigate the associations between computed tomography (CT)-derived biomarkers for adipose tissue and T2D incidence in normoglycemic adults.

Methods And Findings: This study was a population-based multiethnic retrospective cohort of 1,744 participants in the Multi-Ethnic Study of Atherosclerosis (MESA) with normoglycemia (baseline fasting plasma glucose [FPG] less than 100 mg/dL) from 6 United States of America communities.

GIE Editorial Board top 10 topics: advances in GI endoscopy in 2020.

The American Society for Gastrointestinal Endoscopy's Gastrointestinal Endoscopy Editorial Board reviewed a systematic literature search of original endoscopy-related articles published during 2020 in Gastrointestinal Endoscopy and 10 other high-impact medical and gastroenterology journals. Votes from each individual board member were tallied to identify a consensus list of the 10 most significant topic areas in GI endoscopy over the calendar year of study using 4 criteria: significance, novelty, impact on national health, and impact on global health. The 10 areas identified were as follows: artificial intelligence in endoscopy, coronavirus disease 2019 and GI practice, third-space endoscopy, lumen-apposing metal stents, single-use duodenoscopes and other disposable equipment, endosonographic needle technology and techniques, endoscopic closure devices, advances in GI bleeding management, improvements in polypectomy techniques, and bariatric endoscopy.

Effect of Perinatal Vitamin D Deficiency on Lung Mesenchymal Stem Cell Differentiation and Injury Repair Potential.

Stem cells, including the resident lung mesenchymal stem cells (LMSCs), are critically important for injury repair. Compelling evidence links perinatal vitamin D (VD) deficiency to reactive airway disease; however, the effects of perinatal VD deficiency on LMSC function is unknown. We tested the hypothesis that perinatal VD deficiency alters LMSC proliferation, differentiation, and function, leading to an enhanced myogenic phenotype.
