Background: Symptoms of heart failure markedly impair a patient's health status. The aim of this study was to identify predictors of health status in a sample of racially and ethnically diverse patients with heart failure using a web-based mobile health application, mi.Symptoms.
Methods: We conducted a cross-sectional study at an urban academic medical center. Patients with heart failure self-reported symptoms using validated symptom instruments (e.g. patient-reported outcome measurement information system) by way of the mobile health application, mi.Symptoms. The primary study outcome was health status, measured with the Kansas City cardiomyopathy questionnaire clinical summary score. Data were analyzed using descriptive statistics and multiple linear regression.
Results: The mean age of the sample ( n=168) was 58.7 (±12.5) years, 37% were women, 36% were Black, 36% identified as Hispanic/Latino, 48% were classified as New York Heart Association class III, and 44% reported not having enough income to make ends meet. Predictors of better health status in heart failure included higher physical function ( β=0.89, p=0.001) and ability to participate in social roles and activities ( β=0.58, p=0.002), and predictors of poorer health status were New York Heart Association class IV ( β=-11.68, p=0.006) and dyspnea ( β=-0.77, p<0.001). The predictors accounted for 73% of the variance in health status.
Conclusion: Patient-centered interventions should focus on modifiable risk factors that reduce dyspnea, improve functional status, and enhance engagement in social roles to improve the health status of patients with heart failure.

Sequential Epidemiological Analyses of Real-World Data: A Tool for Prospective Drug Safety Surveillance from the Rofecoxib Example.

Introduction: Large administrative healthcare databases can be used for near real-time sequential safety surveillance of drugs as an alternative approach to traditional reporting-based pharmacovigilance. The study aims to build and empirically test a prospective drug safety monitoring setup and perform a sequential safety monitoring of rofecoxib use and risk of cardiovascular outcomes.
Methods: We used Danish population-based health registers and performed sequential analysis of rofecoxib use and cardiovascular outcomes using case-time-control and cohort study designs from January 2000 to September 2004.
Anxiety and Depression Affect Sleep Quality: A Preliminary Investigation in Crowdsourced Samples of Autistic and Non-Autistic Adults.

We aimed to compare sleep problems in autistic and non-autistic adults with co-occurring depression and anxiety. The primary research question was whether autism status influences sleep quality, after accounting for the effects of depression and anxiety. We hypothesized that autistic adults would report higher levels of depression, anxiety, and sleep problems compared to non-autistic adults, after controlling for these covariates.

Objective: To investigate the synergistic effects of combined sleep interventions and enhanced nutritional support on postoperative recovery in colon cancer patients, with a focus on sleep quality, nutritional status, pain management, psychological well-being, and quality of life.
Methods: This randomized controlled trial included 290 postoperative colon cancer patients admitted to the First Affiliated Hospital of Soochow University between May 2021 and May 2023. Participants were randomized into two groups: the intervention group, which received standard care supplemented with sleep and nutritional interventions, and the control group, which received standard care alone.

Background: New CFTR Modulator triple therapy Elexacaftor-Ivacaftor-Tezacaftor (ETI) prove efficacy in pulmonary outcomes. However, its impact on nasal sinus symptoms in children has not been specifically studied. The aim of this study is to evaluate the impact of this therapy on nasal sinus symptomatology in children aged 6-12 years.

Background: Cystic Fibrosis Foundation guidelines recommend human milk (HM) as the ideal source of nutrition for children with CF (cwCF). Despite known pulmonary and nutritional benefits, fewer cwCF ever receive HM compared to the general population. Early nutrition choices are preference-sensitive, yet little is known about the factors that impede or sustain HM feeding among parents of cwCF.
