ABSTRACT Female sex workers (FSWs) are at increased risk of HIV and face significant barriers to clinic-based HIV testing, including provider stigma and privacy constraints. HIV self-testing (HIVST) has been proven to significantly increase HIV testing among FSWs. Less is known, however, about how FSWs make meaning of oral-fluid HIV self-tests, and the unintended ways they use and understand this novel technology. From October 2016 to March 2017, we conducted 61 in-depth interviews with FSWs (n = 31) in Kampala, Uganda. Eligible participants were female, ≥18 years, exchanged sex for money or goods, and had not recently tested for HIV. We used inductive coding to identify emerging themes and re-arranged these into an adapted framework. Unintended desirable ways FSWs described self-testing included as a means to test others, to bolster their reputation as a health-conscious sex worker, and to avoid bearing witness to suffering at health facilities. Unintended undesirable meanings ascribed to self-testing included misunderstandings about how HIV is transmitted (via saliva versus blood) and whether self-tests also test for other infections. HIVST can increase FSWs' knowledge of their own HIV status and that of their sexual partners, but messaging and intervention design must address misunderstandings and misuses of self-testing. Trial registration ClinicalTrials.gov identifier NCT02846402.People living with HIV (PLWH) often experience mental health concerns as well as difficulties with medication adherence; they also report barriers to receipt of health services. Telephone-delivered interventions can overcome some of these barriers. To obtain patients' perspectives on telephone-delivered behavioral health services, we conducted a qualitative study with patients who participated in one of two telephone-delivered interventions (mindfulness training, health coaching) in a research trial. Patients (N = 42; M age = 46 years, 50% female, 26% Black) participated in semi-structured qualitative interviews after completing the study. They identified several advantages (e.g., being able to schedule sessions more flexibly compared to in-person appointments, ease of developing rapport with interventionists) as well as occasional challenges of phone delivery (e.g., network connectivity). Overall, PLWH view telephone-delivery as a convenient and flexible method to engage in behavioral health interventions.The application of big data, radiomics, machine learning, and artificial intelligence (AI) algorithms in radiology requires access to large data sets containing personal health information. Because machine learning projects often require collaboration between different sites or data transfer to a third party, precautions are required to safeguard patient privacy. Safety measures are required to prevent inadvertent access to and transfer of identifiable information. The Canadian Association of Radiologists (CAR) is the national voice of radiology committed to promoting the highest standards in patient-centered imaging, lifelong learning, and research. The CAR has created an AI Ethical and Legal standing committee with the mandate to guide the medical imaging community in terms of best practices in data management, access to health care data, de-identification, and accountability practices. Part 1 of this article will inform CAR members on principles of de-identification, pseudonymization, encryption, direct and indirect identifiers, k-anonymization, risks of reidentification, implementations, data set release models, and validation of AI algorithms, with a view to developing appropriate standards to safeguard patient information effectively.Humans, wildlife, and domestic animals are intimately linked through shared infections. selleck kinase inhibitor and pathogens use multiple host species, either opportunistically or sequentially, such that managing disease risk frequently requires a broader understanding of the ecological community. The coccidian protozoan Toxoplasma gondii infects more than one hundred species of vertebrates, ranging from bats to beluga whales. In humans, acute toxoplasmosis can have serious health consequences for immunocompromised individuals. Even amongst asymptomatic patients, however, toxoplasmosis has been linked to a range of behavioral alterations and conditions, such as changes in risk tolerance, neuroticism, mental illness, suicide, and accident proneness. Whether such links are causal or simply correlational has been the subject of intense study and debate; from an evolutionary standpoint, selection may favor parasite-induced alterations in host behavior that increase the likelihood a host is consumed by the definitive host-in this case a domestic or wild felid. Here, we examine current evidence for parasite-induced manipulations of host behavior, in both humans and other animals. We critically evaluate proposed mechanisms through which infection might influence host behavior, which range from inflammation in the brain to changes in hormones or neurotransmitters. Considering estimates that T. gondii may infect up to one-third of the global human population, we conclude by examining the implications of these changes for human behavior, individual fitness, and emergent cultural properties.This cross-sectional clinical study was designed to explore the impact of tryptophan-kynurenine and tryptophan-serotonin (5 HT) pathways on reproductive performance during in vitro fertilization (IVF). #link# Paired serum and follicular fluid (FF) samples were obtained from 64 consecutive IVF patients. The analysis was done by using LC-MS/MS. Ovarian hyperstimulation resulted in decreased serum tryptophan (p less then 0.004), 5-HT (p less then 0.049) and kynurenine (p less then 0.001). FF levels of tryptophan (R=0.245, p less then 0.051), kynurenine (R=0.556, p less then 0.001) and 5-HT (R=0.523, p less then 0.001) were positively related to their respective serum levels. Clinical pregnancy was associated with higher serum 5-HT (p less then 0.045) and FF 5-HT (p less then 0.020) and lower kynurenine to 5-HT ratio (p less then 0.024). Chemical pregnancy was also positively related to FF 5-HT (R=0.362, p less then 0.024). Moreover, there was a direct relationship of the number of mature oocytes to the FF 5-HT (R=0.363, p less then 0.
