Integrating mental health services into primary care for HIV-infected pregnant and non-pregnant women: whole life—a theoretically derived model for clinical care and outcomes assessment

Poor women of color who are disproportionately both infected and affected by HIV/AIDS also face multiple lifestyle and psychosocial burdens that complicate effective delivery of health care, thereby contributing to their poorer prognosis. Addressing these factors within the context of HIV/AIDS primary care for women is the aim of Whole Life, a program to integrate mental health services into primary care for HIV-infected pregnant and non-pregnant women. Whole Life utilizes a theoretically derived clinical services model that provides data for both clinical care and patient outcomes research within the constraints of a clinical setting. During a woman’s first two clinic visits, data are gathered in structured interviews with standardized instruments—adapted for relevance to the population—that meet clinical and service needs, as well as measure components of the Whole Life model. Interviews are conducted by existing front-line staff who have been trained in using these instruments to gather information typically recorded in clinical notes. The implementation of Whole Life to date clearly demonstrates the feasibility of mental health–primary care services integration in a publicly funded HIV primary care clinic serving poor women of color

Epidemiologic Investigation of Two Welder’s Anthrax Cases Caused by Bacillus cereus Group Bacteria: Occupational Link Established by Environmental Detection

Bacillus cereus group bacteria containing the anthrax toxin genes can cause fatal anthrax pneumonia in welders. Two welder’s anthrax cases identified in 2020 were investigated to determine the source of each patient’s exposure. Environmental sampling was performed at locations where each patient had recent exposure to soil and dust. Samples were tested for the anthrax toxin genes by real-time PCR, and culture was performed on positive samples to identify whether any environmental isolates matched the patient’s clinical isolate. A total of 185 environmental samples were collected in investigation A for patient A and 108 samples in investigation B for patient B. All samples from investigation B were real-time PCR-negative, but 14 (8%) samples from investigation A were positive, including 10 from patient A’s worksite and 4 from his work-related clothing and gear. An isolate genetically matching the one recovered from patient A was successfully cultured from a worksite soil sample. All welder’s anthrax cases should be investigated to determine the source of exposure, which may be linked to their worksite. Welding and metalworking employers should consider conducting a workplace hazard assessment and implementing controls to reduce the risk of occupationally associated illnesses including welder’s anthrax

Mitochondrial Alterations and Oxidative Stress in Cystic Fibrosis

Cystic fibrosis (CF) is the most frequent autosomal recessive disease and is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Since the discovery of the deletion in the phenylalanine 508 site (ΔF508) of the CFTR gene, the study of its function as chloride channel occupied most investigations. Now, we know that CFTR is also involved in the GSH and HCO3− transport, and its function could regulate the mitochondrial function and ROS production. In this way, the notion of the CFTR as a simple chloride channel has begun to change toward a more complex function as molecular hub that integrates different cellular signals. There is a growing body of evidence that shows mitochondrial dysfunctions and increased oxidative stress in CF. Here, we review the mitochondrial defects induced by the altered function of the CFTR in CF, focusing on oxidative stress and inflammation as targets for therapy.Fil: Valdivieso, Ángel Gabriel.
