A group of 66 patients hospitalized for the treatment of closed head injury, were assessed for the presence of mood disorders during their hospital admission and at 3, 6 and 12 months follow-up. A total 28 patients met DSM-III-R diagnostic criteria for major depression at some time during the study (17 in the acute stage, 11 during follow-up). The mean duration of major depression was 4.7 months. However, there appeared to be a group of transiently depressed patients (41%) who where depressed inhospital but were no longer depressed at 3 months follow-up. Throughout the follow-up period, major depression showed a strong relationship with poor social functioning. There was not, however, a consistent relationship between depression and quantitative measures of either physical or cognitive impairment. Location of the brain lesion was associated with the development of major depression only in the acute stage. Transient depressive syndromes were associated with left dorsolateral frontal and/or left basal ganglia lesions.

Of the roughly 38 million people diagnosed with type 2 diabetes mellitus in the United States, up to 34% will develop a diabetic foot ulcer at some point, up to 75% of those who develop an ulcer will experience recurrent ulcers, and approximately 18% of patients with a diabetic foot ulcer will undergo lower-limb amputation. The aim of this study was to determine whether depressive symptoms change after a minor, nontraumatic amputation. We conducted a multimethod study consisting of semi-structured interviews (n = 12) and a retrospective cohort (n = 20) of patients with type 2 diabetes mellitus who underwent a nontraumatic, minor amputation of a single toe (partial or total) or partial ray resection.

Background: Observational studies have reported that sleep is associated with the risk of major depressive disorder (MDD) and cardiovascular diseases (CVDs). However, the causal relationships among various sleep traits remain contentious, and whether MDD mediates the impact of specific sleep traits on CVDs is unclear.
Methods: We performed two-sample Mendelian randomisation analyses to explore whether insomnia, sleep time, daytime napping, daytime sleepiness, chronotype, snoring or obstructive sleep apnoea were causally associated with the risk of five CVDs, including coronary artery disease (CAD), myocardial infarction (MI), heart failure (HF), atrial fibrillation and stroke.

Addiction is a chronic condition that poses a serious public health challenge, particularly highlighted by the global opioid crisis involving drugs such as morphine (MORPH). One of the major obstacles in effective detoxification is the high relapse rate, with many individuals resuming drug use after withdrawal. Pharmacological treatments developed so far have generally shown limited efficacy in addressing substance use disorder.

Background: Depressive disorders (DDs) are the leading causes of disability among adolescents and young adults (AYAs) in China. This study estimated the trends of DDs burden among AYAs in China over the last 32 years, and further predicted to 2030.
Methods: Based on the Global Burden of Disease Study 2021, age-standardized incidence, prevalence, and years lived with disability (YLDs) rates were used to describe the DDs burden among AYAs (aged 15-29 years) in China.

Background: Depression is a common mental disorder that significantly impacts global well-being. Although stress is a major contributor to depression, not all stress leads to depressive outcomes due to differences in stress perception. Understanding the neural mechanisms of stress perception may help identify biomarkers for targeted interventions to alleviate stress-related depression.
