HIV Prevalence,Knowledge, Attitudes,and Practices Among Polydrug Users in Brazil: A Biological Survey Using Respondent Driven Sampling

Brazil has a concentrated HIV epidemic among key populations. In 2009, the Ministry of Health conducted a survey in 10 Brazilian cities aiming to estimate HIV prevalence, knowledge, and associated risk behaviors of polysubstance users (PSU). Using Respondent Driven Sampling (RDS), 3449 PSU were recruited, answered an Audio-Computer Self Assisted Interview (ACASI) and were tested for HIV and syphilis. Analyses were weighted by individual’s social network size generated on RDSAT. Pooled HIV prevalence was 5.8% but varied across cities. Most PSU were male, non-white, without income, unemployed, with low levels of education. Overall, 12.0% used injectable drugs, 48.7% had sex with occasional partners and 46.4% engaged in commercial sex. A majority received free condoms (71.4%) but 76.7% exhibited inconsistent condom use. Findings can support policies aiming to improve health care and preventive interventions tailored to this population that remains at high risk of acquiring and transmitting HIV/STI in multiple scenarios.     

Hormonal and Psychogenic Risk Factors for Erectile Dysfunction in Men with HTLV-1

IntroductionErectile dysfunction (ED) is associated with neurological damage due to human T-lymphotropic virus 1 (HTLV-1) infection, but hormonal and psychogenic factors also cause ED.AimTo evaluate the association of psychogenic and hormonal factors with ED in men infected with HTLV-1.MethodsIn this cross-sectional study, we compared total testosterone, follicle stimulating hormone, luteinizing hormone, prolactin, anxiety symptoms, depressive symptoms, and neurologic manifestations in HTLV-1-infected men with or without ED. The International Index of Erectile Function was used to determine the degree of ED. Participants were grouped according to Osame’s Motor Disability Scale and the Expanded Disability Status Scale: HTLV-1-associated myelopathy or tropical spastic paraparesis (HAM/TSP), probable HAM/TSP, or HTLV-1 carrier. Chi-square and Fisher’s exact tests were used to compare the groups, and regression analyses were used to show predictors of ED.Main Outcome MeasureSexual hormonal levels, psychogenic factors, and neurologic disabilities were found to be associated with ED.ResultsED was associated with age older than 60 years (P < .001), degree of neurologic involvement (P < .001), depression (P = .009), and anxiety (P = .008). In the multivariate analyses, only age and degree of neurological injury remained as risk factors for ED.Clinical ImplicationsNeurological manifestations are a stronger predictor of ED than hormonal and psychogenic factors in HTLV-1-infected men.Strengths & LimitationsThe statistical power of the study was limited due to the low number of participants, but neurologic manifestations were clearly associated with ED. There was no strong association between hormonal and psychogenic factors and ED.ConclusionHormonal and psychogenic factors did not show a strong association with ED in individuals with HTLV-1, but neurological manifestations were strongly associated with ED in these individuals.de Oliveira CJV, Neto, JAC, Andrade RCP, et al.

Influence of intra- and extrauterine factors on infant sleep in the first 6 months of life

ObjectiveInfant sleep problems can affect the child's health. Maternal characteristics have been associated with the quality of infant sleep, but few studies have investigated the impact of intrauterine conditions. The aim of the study was to evaluate the association between adverse intrauterine environments (maternal smoking, hypertension, diabetes, and intrauterine growth restriction) and extrauterine factors on infant sleep in the first 6 months of life.MethodsProspective cohort study, including singleton and at-term infants. Mothers were interviewed after delivery and at 30 days, 3 months, and 6 months of life. Socioeconomic, breastfeeding, and sleep data were self-reported by mothers using semi-structured interviews. Maternal stress (Perceived Stress Scale) and postpartum depression symptoms (Edinburgh Postpartum Depression Scale) were assessed.ResultsThere was no statistically significant association between intrauterine environments and the sleep of infants of the 359 mother–child dyads investigated. Total infant sleep time decreased from approximately 13–11 h from 30 days to 6 months of age (p < 0.001) and the longest period of uninterrupted sleep increased from approximately 4–6 h during the same period (p < 0.001). Breastfed infants slept longer in 24-h periods in the first month, but they woke up more often throughout the night when compared to infants receiving formula. Mothers with depressive symptoms reported increased sleep latency time.ConclusionsAdverse intrauterine environments did not significantly affect sleep measures in the first 6 months of life. Maternal characteristics and practices, however, were associated with infant sleep, suggesting that environmental factors significantly contribute to sleep quality early in life.

Background: Addressing the long-term consequences of stroke is a top 10 research priority, and understanding the views of different stakeholders is essential in designing appropriate patient-centred multidisciplinary rehabilitation.

Aims: This study reports on the perspectives of 38 individuals who live with or work with aphasia: people with aphasia (PWA), family members (FM) and friends, and speech and language therapists (SLTs), about its consequences in the daily lives of PWA.

Method &; Resources: In total, 14 PWA, 14 FM and 10 SLTs participated in the study. All participants were interviewed about the consequences of stroke and aphasia. Small focus groups were used with some participants. In-depth semi-structured interviews were used with other participants. Interviews were carried out in groups or individually in order to accommodate severe aphasic impairments or respondents with fewer years of education. Interviews were video or audio-recorded. Verbal and non-verbal communication was transcribed and analysed qualitatively using content analysis. Data was coded and mapped onto the ICF framework.

Outcomes &; Results: All three groups reported consequences in Body Functions and Body Structures, primarily in Mental Functions (Specific Mental Functions and Global Mental Functions) and Neuromusculoskeletal and Movement-Related Functions. Within Specific Mental Functions, PWA emphasised Expression of Oral Language, whereas FM and SLTs emphasised Emotional Functions. Within Global Mental Functions, PWA and FM emphasised Energy and Drive Functions, whereas SLTs emphasised Temperament and Personality Functions. Some consequences were shared between PWA and SLTs (Sensory Functions and Pain, and Functions of the Digestive, Metabolic and Endocrine Systems), whilst others were specific to SLTs alone (Voice and Speech Functions, and Cardiovascular, Haematological, Immunological and Respiratory Systems). All three groups reported consequences in Activities and Participation in Major Life Areas; Community, Social and Civic Life; Interpersonal Interactions and Relationships; Communication; and Mobility. Some consequences were shared by PWA and FM (Domestic Life), and others by FM and SLT (Self Care). Consequences in General Tasks and Demands were only described by SLTs and in Learning and Applying Knowledge by PWA. Both PWA and FM reported a general Loss of Autonomy.

Conclusions: PWA, FM and SLTs reported a considerable range of stroke and aphasia consequences in the daily life of those who live with it. They were concerned to different degrees with language, physical and emotional changes, and impact on communication, mobility, self-care, relationships, leisure and work. Professionals’ practices in Portugal need to be changed in order to consider these findings.
