Association Between age or Duration of Diagnosis in Obstructive Hypertrophic Cardiomyopathy and Response to Mavacamten Treatment: Exploratory Analysis of the EXPLORER-HCM Trial.

Background And Aims: In patients with symptomatic, obstructive hypertrophic cardiomyopathy (HCM), it is unclear if response to cardiac myosin inhibition varies with older age or a longer duration of diagnosis. This study evaluated the response of these subgroups to mavacamten therapy for all primary, secondary and exploratory endpoints in the EXPLORER-HCM trial (ClinicalTrials.gov: NCT03470545).

Development of a prognostic model to predict 90-day mortality in hospitalised cancer patients (PROMISE tool): a prospective observational study.

Background: Prognostic factors for ambulatory oncology patients have been described, including Eastern Cooperative Oncology Group (ECOG), tumor stage and malnutrition. However, there is no firm evidence on which variables best predict mortality in hospitalized patients receiving active systemic treatment. Our main goal was to develop a predictive model for 90-day mortality upon admission.

Quality of Life and Exercise Capacity in Early Stage and Subclinical Hypertrophic Cardiomyopathy: A Secondary Analysis of the VANISH Trial.

Background: The health-related quality of life (HRQOL) and cardiopulmonary exercise testing (CPET) performance of individuals with subclinical and early stage hypertrophic cardiomyopathy (HCM) have not been systematically studied. Improved understanding will inform the natural history of HCM and factors influencing well-being.

Methods: VANISH trial (Valsartan for Attenuating Disease Evolution in Early Sarcomeric HCM) participants with early stage sarcomeric HCM (primary analysis cohort) and subclinical HCM (sarcomere variant without left ventricular hypertrophy comprising the exploratory cohort) who completed baseline and year 2 HRQOL assessment via the pediatric quality of life inventory and CPET were studied.

Exercise Testing to Unmask Latent LVOT Obstruction in a Highly Symptomatic Patient With Hypertrophic Cardiomyopathy.

Rest imaging in hypertrophic cardiomyopathy may underestimate or miss left ventricular outflow tract obstruction, leading to suboptimal management decisions that negatively affect symptomatic patients. The 2024 hypertrophic cardiomyopathy guidelines describe exercise stress testing as an important tool to determine overall exercise tolerance and latent, exercise-provoked left ventricular outflow tract obstruction.

A Case of Peritoneal Carcinomatosis After Hyperprogression in Human Papillomavirus-Positive (HPV+) Oropharyngeal Squamous Cell Carcinoma.

Immunotherapy has been shown to provide clinical benefit in selected patients with head and neck squamous cell carcinoma (HNSCC), regardless of human papillomavirus (HPV) infection, and including recurrent/metastatic (R/M) platinum refractory tumors. Hyperprogression is an uncommon negative outcome of treatment with immunotherapy. We present the case of a patient with HPV+ HNSCC who presented hyperprogression after immunotherapy and a rare metastasis location with peritoneal carcinomatosis and subcutaneous nodules.

Mechanism of the Sharpless Epoxidation Reaction: A DFT Study.

The Sharpless reaction is an enantioselective epoxidation of prochiral allylic alcohols that employs a Ti(IV) catalyst formed from titanium tetra(isopropoxide), Ti(O--Pr), diethyl tartrate (DET), and the oxidizing agent -butyl hydroperoxide. The M06-2X DFT functional with the 6-311+G(d,p) basis set has been employed to model the structures and energetics of the Sharpless epoxidation reaction. The monomeric tetracoordinate titanium(IV) diethyltartrate is thermodynamically strongly favored to dimerize, producing a pentacoordinate catalyst, [Ti(DET)(O-i-Pr)], that is a more reactive chiral epoxidation catalyst.

Remarkably High Internal Transcribed Spacer Haplotype Diversity of the Fungal Select Agent Discovered Throughout Its Range in Sub-Saharan Africa.

Red leaf blotch of soybean, caused by the fungus , is a foliar disease characterized by blotching, necrosis, and defoliation that has only been reported from Africa. The species is listed as a Select Agent by the Federal Select Agent Program due to its potentially devastating impacts to soybean production should it spread to the United States. Despite its potential import, very few isolates are available for study.

A Systematic Review of Interventions for Obesity Among Adults With Food Insecurity.

Objective: Food insecurity is associated with reduced dietary quality and excess weight gain. However, interventions that are effective for obesity among individuals with food insecurity are unclear. The purpose of this systematic review was to synthesize studies in which authors examined interventions for obesity among adults with food insecurity.

Effect of Mavacamten in Women Compared With Men With Obstructive Hypertrophic Cardiomyopathy: Insights From EXPLORER-HCM.

Background: Compared with men, women with hypertrophic cardiomyopathy (HCM) have a higher incidence of heart failure and worse outcomes. We investigated baseline clinical and echocardiographic characteristics and response to mavacamten among women compared with men in the EXPLORER-HCM study (Clinical Study to Evaluate Mavacamten [MYK-461] in Adults With Symptomatic Obstructive Hypertrophic Cardiomyopathy).

Methods: A prespecified post hoc analysis of sex from the blinded, randomized EXPLORER-HCM trial of mavacamten versus placebo in symptomatic patients with obstructive HCM was performed.

In ischemic LV dysfunction, adding PCI to medical therapy did not reduce a composite of death or aborted sudden death.

Arrhythmia and death following percutaneous revascularization in ischemic left ventricular dysfunction: prespecified analyses from the REVIVED-BCIS2 trial. Circulation. 2023;148:862-871.

Cardiac Remodeling in Subclinical Hypertrophic Cardiomyopathy: The VANISH Randomized Clinical Trial.

Importance: Valsartan has shown promise in attenuating cardiac remodeling in patients with early-stage sarcomeric hypertrophic cardiomyopathy (HCM). Genetic testing can identify individuals at risk of HCM in a subclinical stage who could benefit from therapies that prevent disease progression.

Objective: To explore the potential for valsartan to modify disease development, and to characterize short-term phenotypic progression in subclinical HCM.

Population mental health in Burma after 2021 military coup: online non-probability survey.

Background: Humanitarian crises and armed conflicts lead to a greater prevalence of poor population mental health. Following the 1 February 2021 military coup in Burma, the country's civilians have faced humanitarian crises that have probably caused rising rates of mental disorders. However, a dearth of data has prevented researchers from assessing the extent of the problem empirically.

Gulf war illness inflammation reduction trial: A phase 2 randomized controlled trial of low-dose prednisone chronotherapy, effects on health-related quality of life.

Background: Gulf War illness (GWI) is a deployment-related chronic multisymptom illness impacting the health-related quality of life (HRQOL) of many U.S. Military Veterans of the 1990-91 Gulf War.

A preregistered vignette experiment on determinants of health data sharing behavior .

The COVID-19 pandemic has spotlighted the importance of high-quality data for empirical health research and evidence-based political decision-making. To leverage the full potential of these data, a better understanding of the determinants and conditions under which people are willing to share their health data is critical. Building on the privacy theory of contextual integrity, the privacy calculus, and previous findings regarding different data types and recipients, we argue that established social norms shape the acceptance of novel practices of data collection and use.

A nationwide 104 weeks real-world study of dupilumab in adults with atopic dermatitis: Ineffectiveness in head-and-neck dermatitis.

Background: Evaluation of effectiveness and safety of new systemic treatments for atopic dermatitis (AD) after approval is important. There are few published data exceeding 52-week therapy with dupilumab.

Objectives: To examine the safety, effectiveness and drug survival of dupilumab in a Danish nationwide cohort with moderate-to-severe AD up to 104 weeks exposure.

From fair predictions to just decisions? Conceptualizing algorithmic fairness and distributive justice in the context of data-driven decision-making.

Prediction algorithms are regularly used to support and automate high-stakes policy decisions about the allocation of scarce public resources. However, data-driven decision-making raises problems of algorithmic fairness and justice. So far, fairness and justice are frequently conflated, with the consequence that distributive justice concerns are not addressed explicitly.
