Article Abstract

Objectives: We assessed sedentary behavior (SB) patterns and examined its associations, by domain, with cardiovascular disease (CVD) risk measures in desk workers ( N = 273).

Methods: Sedentary behavior was measured by activPAL3 and partitioned into occupational and nonoccupational SB. Cardiovascular disease risk measures included blood pressure, pulse wave velocity, heart rate, and heart rate variability. Paired t tests evaluated patterns of SB across domains. Linear regressions estimated associations of occupational and nonoccupational SB with CVD risk measures.

Results: Participants spent 69% of their time in SB; higher proportions were accumulated during occupational versus nonoccupational time. Higher all-domain SB was only associated with higher pulse wave velocity. Paradoxically, greater nonoccupational SB unfavorably associated with CVD risk measures, while higher occupational SB favorably correlated to CVD risk measures.

Conclusions: Observed paradoxical associations suggest that domain should be considered in efforts to improve cardiovascular health by reducing SB.

Ionic liquids (ILs) are a class of organic salts with melting points below 100°C. Owing to their unique chemical and physical properties, they are used as solvents and catalysts in various chemical transformations, progressively replacing common volatile organic solvents (VOCs) in green synthetic applications. However, their intrinsic ionic nature can restrict the use of mass spectrometric techniques to monitor the time progress of a reaction occurring in an IL medium, thus preventing one from following the formation of the reaction products or intercepting the reaction intermediates.

Introduction: People with rheumatic and musculoskeletal diseases are advised to do aerobic exercise for symptom relief and to reduce the risk of cardiovascular disease. Continuous exercise at an intensity causing a rate of perceived exertion of 15, on a 6-20-point Borg scale, exemplifies such exercise. Also, the instruction "Now you need to increase your heart rate" is used before aerobic exercise.

Introduction: Simple screening tools are critical for assessing Alzheimer's disease (AD)-related pre-dementia changes. This study investigated longitudinal scores from the Quick Dementia Rating System (QDRS), a brief study partner-reported measure, in relation to baseline levels of the AD biomarker plasma pTau217 in individuals unimpaired at baseline.

Methods: Data from the Wisconsin Registry for Alzheimer's Prevention (N = 639) were used to examine whether baseline plasma pTau217 (ALZpath assay on Quanterix platform) modified QDRS or Preclinical Alzheimer's Cognitive Composite (PACC3) trajectories (mixed-effects models; time = age).

Background: Acupuncture is a widely recognized complementary therapy with proven therapeutic benefits; however, concerns regarding patient safety persist due to adverse events ranging from minor complications to severe outcomes like pneumothorax and nerve injury.

Objective: This study aims to identify common adverse events in acupuncture, propose innovative risk mitigation strategies, establish standardized best practices, enhance practitioner training, and examine global disparities in safety protocols.

Design: Comprehensive review of existing literature, clinical case studies, and international safety guidelines.

Background: Metabolic reprogramming is an important hallmark of cervical cancer (CC), and extensive studies have provided important information for translational and clinical oncology. Here we sought to determine metabolic association with molecular aberrations, telomere maintenance and outcomes in CC.

Methods: RNA sequencing data from TCGA cohort of CC was analyzed for their metabolic gene expression profile and consensus clustering was then performed to classify tumors into different groups/subtypes.
