67 patients with miliary TB diagnosed over a 15 year period (1973-1987) have been retrospectively studied. The clinical and analysis data were evaluated, highlighting different factors associated to higher mortality. 53 patients diagnoses were made premortem and 14 had the diagnosis made post-mortem. The age of the patients was of 48 +/- 21 (mean +/- DE) years, inferior to other series, this showing a higher prevalence and early age of infection in the area. 63% had miliary radiological features; the most frequent tests performed were liver biopsy with profitability of 80% and bronchoscopy which, together with transbronchial biopsy and bacterial analysis of the bronchoalveolar lavage, showed a positive diagnosis of 60%. The factors which were associated with bad prognosis were cavitated or chronic lesions (P less than 0.01), chronic diseases and immunosuppression factors associated, this not being statistically significant.

Near-infrared spectroscopy combined with vascular occlusion test to predict acute kidney injury in patients undergoing cardiac surgery: a prospective observational study.
J Cardiothorac Surg

Department of Anesthesiology, West China Hospital, Sichuan University, 37 Guo Xue Xiang, Chengdu, 610041, China.
Background: Near-infrared spectroscopy (NIRS) enables a non-invasive measurement of tissue oxygen saturation (StO) in regions illuminated by near-infrared lights. Vascular occlusion test (VOT) serves as a model to artificially induce forearm ischemia-reperfusion. The combination of StO monitoring and VOT allows for dynamic evaluation of the balance between oxygen delivery and consumption in tissue, as well as the functional reserve of microcirculation.

Objective: This study aimed to evaluate CTF1 expression in glioma, its relationship to patient prognosis and the tumor immune microenvironment, and effects on glioma phenotypes to identify a new therapeutic target for treating glioma precisely.
Methods: We initially assessed the expression of CTF1, a member of the IL-6 family, in glioma, using bioinformatics tools and publicly available databases. Furthermore, we examined the correlation between CTF1 expression and tumor prognosis, DNA methylation patterns, m6A-related genes, potential biological functions, the immune microenvironment, and genes associated with immune checkpoints.
Awareness and knowledge regarding female genital schistosomiasis among European healthcare workers: a cross-sectional online survey.
Global Health
January 2025
Research Group: Implementation Research, Bernhard Nocht Institute for Tropical Medicine, Hamburg, Germany.
Background: Adequate knowledge and awareness regarding diseases are essential for appropriate, high-quality healthcare. Female Genital Schistosomiasis (FGS) is a non-sexually transmitted gynaecological disease that is caused by the presence of Schistosoma haematobium eggs in the female genital tract and the resulting immune response that causes tissue damage. It is estimated to affect 56 million women, mostly in sub-Saharan Africa (SSA), where healthcare workers (HCWs) have limited awareness and knowledge of FGS.

Department of Public Health, Woldia University, Woldia, Ethiopia.
Background: Despite advancements in Human Immunodeficiency Virus (HIV) treatment and care, undernutrition remains a significant concern, accelerating disease progression and risk of Acquired Immune Deficiency Syndrome (AIDS)-related deaths. The nutritional status of second-line antiretroviral treatment (SLART) users in Ethiopia has not been thoroughly investigated. So, this study aimed to assess the nutritional status of HIV/AIDS patients who were on SLART and its associated factors in Northern Ethiopia.

Background: Self-management is regarded as a crucial factor influencing the effectiveness of home-based cardiac rehabilitation for patients with coronary heart disease. In nursing practice, nurses employ a variety of strategies to enhance self-management of patients. However, there exists a disparity in nurses' perceptions and practical experiences with these strategies.
