Background: Guideline-recommended strategies to interrupt chronic anticoagulation with warfarin or direct oral anticoagulants (DOAC) during the perioperative period of cardiac implantable electronic device (CIED) surgery differ worldwide. There is uncertainty concerning the benefits and harms of interrupted and uninterrupted anticoagulation in patients undergoing CIED surgery.

Objectives: To assess the benefits and harms of interrupted anticoagulation (IAC) with either warfarin or DOAC in the perioperative period of CIED surgery versus uninterrupted anticoagulation (UAC), with or without heparin bridging, during an equivalent time frame, for CIED surgery.

Background: Underserved and underrepresented populations often lack access to affordable, quality healthcare, educational resources, and nutritious foods, all of which contribute to increased risk of Type 2 Diabetes and gout. Type 2 Diabetes is a condition characterized by the denaturation of the insulin receptors, due to chronically high blood glucose levels, leading to impaired regulation of blood sugar. Gout is a chronic inflammatory disease affecting joints in the lower limbs, marked by elevated serum urate levels and the accumulation of uric acid crystals in synovial fluid, causing painful flare-ups that significantly impact quality of life.

We systematically evaluated effects of Mediterranean diets (MED) on cardiovascular (CV) disease and risk factors in overweight or obese adults. Five engines and two registries were searched until October 2023 for randomized controlled trials (RCTs) evaluating any type of MED compared to other diets or advice in adults. Outcomes of interest were clinical outcomes and CV risk factors (anthropometric, lipids, blood pressure, glucose metabolism, liver function).

Article Synopsis
  • A systematic review and meta-analysis was conducted to evaluate the effectiveness and safety of ivermectin in treating early COVID-19 in non-hospitalized patients, using data from five databases up to October 2023.
  • The analysis included 12 randomized controlled trials with over 7,000 adult patients, comparing ivermectin to standard care, placebo, or other active drugs, focusing on outcomes like hospitalization, mortality, adverse events, and clinical improvement.
  • The findings indicated that ivermectin did not significantly reduce hospitalization, mortality, or adverse events compared to control groups, leading to the conclusion that it should not be recommended for treating non-hospitalized COVID-19 patients.

The white stork () is a ciconiiform species widely represented in zoological institutions. Plasma protein electrophoresis is widely used in avian patients for assessment of inflammatory conditions, but reference intervals for this testing modality are lacking for the white stork. The two main electrophoretic methods are agarose gel electrophoresis (AGE) and capillary zone electrophoresis (CZE).

Plasma electrophoresis is an ancillary diagnostic tool in avian medicine, with agarose gel electrophoresis (AGE) and capillary zone electrophoresis (CZE) being the most common techniques. Frozen samples can be used for quantitative studies or comparative diagnostic purposes, but stability of avian plasma proteins under freezing is poorly described. To evaluate the influence of plasma freezing on electrophoretograms in white storks (), heparin blood was sampled from 30 individuals during annual health examinations.

Background: A growing body of research supports the negative impact of anticholinergic drug burden on physical frailty. However, prior research has been limited to homogeneous white European populations, and few studies have evaluated how anticholinergic burden tools compare in their measurement function and reliability with minority community-dwelling adult populations. This study investigated the association between anticholinergic drug exposure and frailty by conducting a sensitivity analysis using multiple anticholinergic burden tools in a diverse cohort.

Uric acid is the final product of purine metabolism and is converted to allantoin in most mammals via the uricase enzyme. The accumulation of loss of function mutations in the gene rendered hominoids (apes and humans) to have higher urate concentrations compared to other mammals. The loss of human uricase activity may have allowed humans to survive environmental stressors, evolution bottlenecks, and life-threatening pathogens.

Nonalcoholic fatty liver disease (NAFLD) is currently the most common form of chronic liver disease. The growing prevalence of NAFLD is strongly associated with the high incidence of metabolic syndrome. NAFLD affects as much as 19% of the US population with a disproportionate impact on minority racial groups such as Asian Americans.

The promise of viral vector-based gene therapy (GT) as a transformative paradigm for treating severely debilitating and life-threatening diseases is slowly coming to fruition with the recent approval of several drug products. However, they have a unique mechanism of action often necessitating a tortuous clinical development plan. Expertise in such complex therapeutic modality is still fairly limited in this emerging class of adeno-associated virus (AAV) vector-based gene therapies.

The growing prevalence of cardiovascular diseases in the United States (US) has disproportionately affected minority populations more than their white counterparts. A population that is often overlooked is the Asian American population, particularly Southeastern Asian immigrants. Despite having relatively favorable socioeconomic indicators compared to the general US population, Asian Americans, specifically Southeast Asian individuals, face a significant burden of traditional cardiovascular risk factors and are considered a high cardiovascular disease risk group.

Study Objectives: In-laboratory polysomnography is recommended for the evaluation of obstructive sleep apnea (OSA) in youth with Down syndrome. However, insufficient sleep laboratories are available, particularly for youth with neurocognitive disabilities such as Down syndrome. We hypothesized that level II home sleep apnea testing (HSAT) would be feasible, acceptable, and accurate in detecting polysomnography-defined moderate-severe OSA in youth with Down syndrome.

Article Synopsis
  • Statins, like rosuvastatin, are commonly used to prevent cardiovascular diseases but can cause muscle-related side effects that lead to patients not sticking to their treatment.
  • Different patient groups metabolize rosuvastatin differently due to genetic variations, particularly in certain Asian populations where a specific missense variant is more prevalent.
  • This genetic variability suggests that rosuvastatin dosing should shift from race-based approaches to genotype-based strategies, emphasizing the need for tailored starting doses, especially lower ones for Filipinos.
