Background: Depression and anxiety are frequent comorbid conditions in cardiovascular diseases (CVDs); they are related to poor prognosis and higher mortality risk. Health providers need a clinical tool to identify these psychiatric conditions. The 14-item hospital anxiety and depression scale (HADS) is a screening tool used in patients with different medical conditions.
Objective: The aim of this study was to evaluate the psychometric properties of the HADS Mexican Spanish version in a broad sample of Mexican patients with CVDs.
Materials And Methods: A total of 953 individuals between 18 and 75 years old with ischemic or hypertensive cardiomyopathy were screened with the HADS Mexican Spanish version. Construct validity, internal consistency, and congruence coefficients of the scale were obtained.
Results: The results showed two clear factors which correspond to the original two designated domains of the HADS, anxiety, and depression, with adequate reliability values (alpha > 0.80) and high congruence coefficients (> 0.90) when compared to the sample of other validation studies of the HADS.
Conclusions: The present study adds evidence of the validity and reliability of the HADS to assess the presence of both depression and anxiety in Mexican patients with CVD. Its central contribution is that it demonstrates its capacity to differentiate the presence and severity of depression and anxiety in this population.

School of Medicine, Trinity College Dublin, Dublin, Ireland.
Purpose: As the global population of older adults rises, the United Nations Decade of Healthy Ageing (2021-2030) advocates for disease prevention, management, and enhancing overall wellbeing in older adults. We reviewed the MEDLINE literature under the MeSH term "music therapy" (MT), for its role in promoting healthy ageing.
Methods: A systematic search of the MEDLINE biomedical database (Ovid) was conducted using "MT" and "Ageing" as keywords, retrieving relevant full-text studies in English.

Altitude training has been widely adopted. This study aimed to establish a mice model to determine the time point for achieving the best endurance at the lowland. C57BL/6 and BALB/c male mice were used to establish a mice model of hypoxic training with normoxic training mice, hypoxic mice, and normoxic mice as controls.

Understanding how the brain distinguishes emotional from neutral scenes is crucial for advancing brain-computer interfaces, enabling real-time emotion detection for faster, more effective responses, and improving treatments for emotional disorders like depression and anxiety. However, inconsistent research findings have arisen from differences in study settings, such as variations in the time windows, brain regions, and emotion categories examined across studies. This review sought to compile the existing literature on the timing at which the adult brain differentiates basic affective from neutral scenes in less than one second, as previous studies have consistently shown that the brain can begin recognizing emotions within just a few milliseconds.

Purpose: To elucidate the structural-functional connectivity (SC-FC) coupling in white matter (WM) tracts in patients with major depressive disorder (MDD).
Methods: A total of 178 individuals diagnosed with MDD and 173 healthy controls (HCs) were recruited for this study. The Euclidean distance was calculated to assess SC-FC coupling.

Introduction/objective: Emotional, mental, or psychological distress, defined as increased symptoms of depression, anxiety, and/or stress, is common in patients with chronic diseases, such as cardiovascular (CV) disease (CVD).
Methods: Literature was reviewed regarding data from studies and meta-analyses examining the impact of emotional stress on the occurrence and outcome of several CVDs (coronary disease, heart failure, hypertension, arrhythmias, stroke). These influences' pathophysiology and clinical spectrum are detailed, tabulated, and pictorially illustrated.
