Article Abstract

Somatic and F-specific coliphages are gaining ground as indicators of fecal/viral pollution. Guidelines and regulations worldwide for monitoring water, biosolids and food are including them as parameters to assess quality and treatment efficiency. Robust methods to detect and quantify both groups of phages in water samples have been launched by agencies such as the International Standardization Organization (ISO) and the USA Environmental Protection Agency (USEPA). Although these methods have proved readily implementable in routine microbiology laboratories, faster and more user-friendly protocols will be highly welcome if coliphage detection becomes routine in water quality analysis. We here provide an overview of new approaches seeking to facilitate the detection of infectious coliphages included in guidelines and regulations. The improvements achieved suggest that streamlined kits able to provide results in a few hours at very reasonable costs will become available in the near future. The potential of molecular procedures and methods based on microelectronic sensors is also briefly discussed.

Background: In Germany, digital transformation and legal regulations are leading to the need to integrate digital technologies into the nursing profession. In addition, to nursing practice, they are also being incorporated into nursing training. Despite comprehensive regulations regarding the use of digital teaching and learning media in nursing education, their specific applicability and implementation vary.

Background: The role of social determinants of health (SDH) in patient outcomes, quality of life, and overall well-being has been well documented. However, the inclusion of these variables in randomized control trials (RCTs) remains limited; thus, the extent of generalizability from such trials is brought into question. The purpose of this study is to explore the rates of reporting SDH variables in RCTs focused on shoulder surgery from the past decade.

Introduction: Binge Eating Disorder (BED) has high lifetime prevalence rates, low treatment success rates, and high rates of treatment dissatisfaction, early discontinuation of care, and recurrence. Complementary and integrative health (CIH) interventions (non-mainstream practices used with conventional approaches for whole-person treatment) hold potential to overcome many treatment barriers and improve BED treatment outcomes. Some CIH interventions have empirical support for use in eating disorders.

The mining industry, including uranium mining and milling, is of high importance in Canada. It is, however, important to consider that ore processing can result in the creation of by-products that contain radionuclides such as radium-226 (Ra). Even with the strict discharge regulations in place, there is limited evidence to suggest that the current Canadian regulatory thresholds for Ra are protective for aquatic life.

Objective: The present study was designed to comprehensively analyze the expression profiles of peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α), estrogen-related receptor-α (ERRα), estrogen receptor-β (ERβ), interleukin-6 (IL-6), cysteinyl-aspartic acid-specific protease-3 (caspase-3), and cysteinyl-aspartic acid-specific protease-9 (caspase-9) in endometriosis tissues. It also aimed to elucidate the hitherto unclarified role of PGC-1α in the processes of proliferation, apoptosis, and gene expression regulation of human endometrial stromal cells, thereby providing novel insights and identifying potential molecular targets for advancing endometriosis treatment modalities.

Methods: A total of 49 ectopic endometrial tissue samples and 50 normal endometrial tissue samples were meticulously collected from patients who underwent gynecological surgeries in the People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine in Fuzhou, China, between January 2022 and January 2023.
