HIV Risk and Gender in Jamaica’s Homeless Population

Rigorous HIV-related data for the homeless population in Jamaica is limited. A cross-sectional survey using a venue-based sampling approach was conducted in 2015 to derive HIV prevalence and associated risk factors. Three hundred twenty-three homeless persons from the parishes of St. James, St. Ann, Kingston, and St. Andrew (the main urban centers) participated. HIV prevalence was 13.8%, with a difference in gender (males 11.6%, females 26.7%, P?=?.007). Sex work, multiple partnerships, incarceration, non-injecting drug use, and female rape were common among the participants. Long-term, multilayered, HIV-specific, female-focused interventions are required for the population, along with additional female-centric research.     

Mycobacterium tuberculosis infection in systemic lupus erythematosus patients

Aim of the work

To estimate prevalence of tuberculosis (TB) infection in systemic lupus erythematosus (SLE) patients; to study its relation to disease duration, activity, damage and treatment as well as to compare the performance of interferon gamma (IFN-γ) release assay and tuberculin skin test (TST) in detection of TB infection.

Unmet needs for services for older adults with mental illness: comparison of views of different stakeholder groups.

OBJECTIVE: The authors assessed the need for mental health services among older adults in San Diego County, California, by determining what needs were not being addressed by existing services, what services were necessary to address these needs, and how much consensus there was among different stakeholders with respect to the problems and solutions related to service delivery. METHODS: Semistructured interviews were conducted with 23 health care and social service providers and administrators, 16 services consumers and other older adults (55 years of age and older), and 19 caregivers/family members and patient/client advocates. This was followed by four focus groups comprised of 18 providers and administrators, six focus groups comprised of 50 consumers and other older adults, and five focus groups comprised of 39 caregivers (family members and advocates). RESULTS: The unmet needs fell into three categories: mental health services, physical health services, and social services. Two interrelated themes were identified by participants: 1) the need for age-appropriate and culturally appropriate services to overcome barriers to mental health services access, use, and quality; and 2) the interrelations between unmet needs that address prevention as well as treatment of mental illness, including socialization and social support, transportation, housing, and physical health care. Differences in stakeholder assessment of unmet needs were associated with respective roles in delivery and use of mental health services. CONCLUSION: Age-appropriate and culturally appropriate solutions that address both prevention and treatment may represent the best strategies for addressing the challenges of mental illness and are most likely to be endorsed by all three groups of stakeholders.     

Altered hippocampal muscarinic M4, but not M1, receptor expression from subjects with schizophrenia.

BACKGROUND: Having shown a decrease in [3H]pirenzepine binding in the hippocampus from subjects with schizophrenia, we wished to determine whether such a change in radioligand binding was associated with changes in hippocampal mRNA for the muscarinic1 (M1) and muscarinic4 (M4) receptors in tissue from different cohorts of subjects. METHOD: The [3H]pirenzepine binding using autoradiography and in situ hybridization with oligonucleotides specific for muscarinic M1 and M4 receptors were completed using hippocampal tissue obtained postmortem from 20 control subjects and 20 subjects with schizophrenia. RESULTS: The [3H]pirenzepine binding was decreased in the dentate gyrus (p < .05), CA3 (p < .01), CA2 (p < .05), and CA1 (p < .01) regions of the hippocampus from subjects with schizophrenia. Levels of M4 mRNA varied with the diagnosis of schizophrenia (p = .01), but significant region-specific changes were not apparent. Changes in levels of mRNA for the muscarinic M1 receptor were not detected with diagnosis. CONCLUSIONS: This study suggests that decreases in hippocampal [3H]pirenzepine binding in subjects with schizophrenia are most likely associated with widespread changes in expression levels of the M4 receptor. These data further implicate the hippocampal formation in the pathology of schizophrenia.
