Background: Obstructive sleep apnea (OSA) prevalence has risen significantly, affecting millions globally and posing a major healthcare burden. OSA is strongly associated with cardiovascular diseases (CVD) such as heart failure, stroke, and ischemic heart disease. However, trends in CVD-related mortality among individuals with OSA remain underexplored.

Sewing the SEAMs: Surgical Education in the Art Museum.

Objective: The field of surgery is highly visual and technical. Yet, there is a paucity of data evaluating how a mandatory visual arts-based workshop may benefit surgical trainees. We report upon the feasibility of and short-term outcomes of a novel, visual art-based curriculum for surgery residents.

Disparities in cervical cancer elimination timeframes in the United States: a comparative modeling study.

Population-level estimates in timeframes for reaching cervical cancer (CC) elimination (ie, <4 cases per 100,000 women) in the United States may mask potential disparities in achieving elimination among sub-populations. We used three independent Cancer Intervention and Surveillance Modeling Network (CISNET) models to estimate differences in the time to CC elimination across seven strata of correlated screening and human papillomavirus vaccination uptake, based on national survey data. Compared to the average population, elimination was achieved ≥22 years earlier for the high-uptake strata and ≥27 years later for the most extreme low-uptake strata.

The Last Decade in Cardiac Amyloidosis: Advances in Understanding Pathophysiology, Diagnosis and Quantification, Prognosis, Treatment Strategies, and Monitoring Response.

Cardiac amyloidosis represents a unique disease process characterized by amyloid fibril deposition within the myocardial extracellular space. Advances in multimodality cardiac imaging enable accurate diagnosis and facilitate prompt initiation of disease-modifying therapies. Furthermore, rapid advances in multimodality imaging have enriched understanding of the underlying pathogenesis, enhanced prognostication, and resulted in the development of imaging-based markers that reflect the amyloid burden, which is of increasing importance when assessing the response to treatment.

Defining the Optimal Dose for 3-Dimensional Conformal Accelerated Partial Breast Irradiation: 15-Year Follow-Up of a Dose-Escalation Trial.

Purpose: Randomized trials have demonstrated similar local tumor control in patients treated with accelerated partial-breast irradiation (APBI) compared with whole-breast irradiation. However, the optimal APBI dose for maximizing tumor control and minimizing toxicity is uncertain.

Methods And Materials: We enrolled patients ≥18 years of age with grade 1 or 2 ductal carcinoma in situ or stage I invasive breast cancer and resection margins ≥2 mm between 2003 and 2011 to a sequential dose-escalation trial using 3-dimensional conformal external beam APBI giving twice daily 4 Gy fractions with total doses of 32 Gy, 36 Gy, and 40 Gy.

Growth Differentiation Factor-15 Is Associated With Congestion-Related Anorexia and Weight Loss in Advanced Heart Failure.

Background: Growth differentiation factor (GDF)-15 is a pleiotropic cytokine that is associated with appetite-suppressing effects and weight loss in patients with malignancy.

Objectives: This study aims to investigate the relationships between GDF-15 levels, anorexia, cachexia, and clinical outcomes in patients with advanced heart failure with reduced ejection fraction (HFrEF).

Methods: In this observational, retrospective analysis, a total of 344 patients with advanced HFrEF (age 58 ± 10 years, 85% male, 67% NYHA functional class III), underwent clinical and echocardiographic examination, body composition evaluation by skinfolds and dual-energy x-ray absorptiometry, circulating metabolite assessment, Minnesota Living with Heart Failure Questionnaire, and right heart catheterization.

Digital Solutions for the Optimization of Pharmacologic Therapy for Heart Failure.

Data from large-scale, randomized, controlled trials demonstrate that contemporary treatments for heart failure (HF) can substantially improve morbidity and mortality. Despite this, observed outcomes for patients living with HF are poor, and they have not improved over time. The are many potential reasons for this important problem, but inadequate use of optimal medical therapy for patients with HF, an important component of guideline-directed medical therapy, in routine practice is a principal and modifiable contributor.

Variations in Revascularization Strategies for Chronic Limb-Threatening Ischemia: A Nationwide Analysis of Medicare Beneficiaries.

Background: Recent data support both surgical-first and endovascular-first revascularization approaches for chronic limb-threatening ischemia (CLTI), but hospital-based practices are poorly described.

Objectives: This aim of this study was to characterize contemporary variations and outcomes associated with each strategy among U.S.

Inpatient Hospitalizations for COVID-19 Among Patients With Prader-Willi Syndrome: A National Inpatient Sample Analysis.

Prader-Willi syndrome (PWS) is a genetic disorder associated with baseline respiratory impairment caused by multiple contributing etiologies. While this may be expected to increase the risk of severe COVID-19 infections in PWS patients, survey studies have suggested paradoxically low disease severity. To better characterize the course of COVID-19 infection in patients with PWS, this study analyses the outcomes of hospitalizations for COVID-19 among patients with and without PWS.

Revisiting the Neuropsychological and Clinical Profile of Mosaic Turner Syndrome With a Ring X Chromosome.

Determining karyotype-phenotype correlations for individuals with Turner syndrome ("TS individuals") is a longstanding research endeavor. The limited literature on Turner syndrome (TS) with a ring X chromosome hinders counseling about the neuropsychological and clinical features. To further characterize these phenotypes, we compared 27 TS individuals with 46,X,r(X)/45,X ("ring X") to 50 non-mosaic 45,X, and 27 mosaic 45,X/46,XX ("mosaic 45,X") individuals.

The Impacts of Programs and Policies to Address Food Insecurity: An Analysis of Change in Income.

Background/objectives: This paper examines hunger over time to analyze how food insecurity is impacted by reduced income, including household funding from the government. Federal policies and community-based programs have the ability to prevent increases in food insecurity, particularly for populations that have risk factors, such as households with children; single-parent households; low-income households, especially those in rural areas; Black and Hispanic households; and, households experiencing economic hardships.

Methods: This study is bas ed on a cross-sectional survey that was administered in 2018 and 2019 to food pantry clients, an already food insecure population accessing resources, in Eastern Massachusetts.

Metabolic Adaptation and Its Determinants in Adolescents Two Years After Sleeve Gastrectomy.

Weight loss is associated with reductions in resting energy expenditure (REE), which are impacted by changes in body composition following sleeve gastrectomy (SG). Current data regarding changes in measured REE (mREE) and metabolic adaptation in adolescents after SG are limited. We evaluated changes in mREE, metabolic adaptation, and body composition in youths after SG vs.

Educational Intervention Boosts Dietitians' Knowledge of the Safety and Approval of Low- and No-Calorie Sweeteners.

Background/objectives: Low- and no-calorie sweeteners (LNCSs) provide sweetness in food applications that are suggested to support consumers' reduced consumption of caloric sweeteners and added sugar intake. Consumers seek guidance and advice on using LNCSs from healthcare providers, including dietitians and nutritionists. However, prior research suggests there may be inconsistent guidance on the use of LNCSs.

Optimized Prime Editing of Human Induced Pluripotent Stem Cells to Efficiently Generate Isogenic Models of Mendelian Diseases.

Prime editing (PE) is a CRISPR-based tool for genome engineering that can be applied to generate human induced pluripotent stem cell (hiPSC)-based disease models. PE technology safely introduces point mutations, small insertions, and deletions (indels) into the genome. It uses a Cas9-nickase (nCas9) fused to a reverse transcriptase (RT) as an editor and a PE guide RNA (pegRNA), which introduces the desired edit with great precision without creating double-strand breaks (DSBs).

Stereoselective Conversions of Carbohydrate Anomeric Hydroxyl Group in Basic and Neutral Conditions.

The rapidly growing glycoscience has boosted the research on the synthesis of glycans and their conjugates, which are centered on the stereoselective formation of glycosidic bonds. Compared to the mainstream acid-promoted glycosylation method that undergoes the S1 type mechanism, the basic/neutral conditions give better stereo control via the S2 mechanism. Anomeric hydroxyl group transformation, whether to form glycosidic bonds directly or to install a leaving group for later glycosylation, is key to carbohydrate synthesis, and the strategies in the stereo control of these reactions under basic/neutral conditions are summarized in this review.

Effects of maze appearance on maze solving.

As mazes are typically complex, cluttered stimuli, solving them is likely limited by visual crowding. Thus, several aspects of the appearance of the maze - the thickness, spacing, and curvature of the paths, as well as the texture of both paths and walls - likely influence the performance. In the current study, we investigate the effects of perceptual aspects of maze design on maze-solving performance to understand the role of crowding and visual complexity.

Forging new paths in the development of community mental health interventions for people with mental illness at risk of criminal legal system contact.

Background: Individuals with serious mental illness (SMI) have disproportionately high rates of criminal legal system involvement. For many, this becomes a repeated cycle of arrest and incarceration. Treatments that address symptoms of mental illness are a critical component of the continuum of services for people with SMI in the legal system; yet on their own, psychiatric treatments have not been successful at reducing criminal legal system involvement for this population.

Amyloid-related imaging abnormalities: manifestations, metrics and mechanisms.

Three monoclonal antibodies directed against specific forms of the amyloid-β (Aβ) peptide have been granted accelerated or traditional approval by the FDA as treatments for Alzheimer disease, representing the first step towards bringing disease-modifying treatments for this disease into clinical practice. Here, we review the detection, underlying pathophysiological mechanisms and clinical implications of amyloid-related imaging abnormalities (ARIA), the most impactful adverse effect of anti-Aβ immunotherapy. ARIA appears as regions of oedema or effusions (ARIA-E) in brain parenchyma or sulci or as haemorrhagic lesions (ARIA-H) in the form of cerebral microbleeds, convexity subarachnoid haemorrhage, cortical superficial siderosis or intracerebral haemorrhage.
