In vivo neuropathology of cortical changes in elderly persons with schizophrenia.

BACKGROUND: Elderly schizophrenia patients frequently develop cognitive impairment of unclear etiology. Magnetic resonance imaging (MRI) studies revealed brain structural abnormalities, but the pattern of cortical gray matter (GM) volume and its relationship with cognitive and behavioral symptoms are unknown. METHODS: Magnetic resonance scans were taken from elderly schizophrenia patients (n = 20, age 67 +/- 6 SD, Mini-Mental State Examination [MMSE] 23 +/- 4), Alzheimer's disease (AD) patients (n = 20, age 73 +/- 9, MMSE 22 +/- 4), and healthy elders (n = 20, age 73 +/- 8, MMSE 29 +/- 1). Patients were assessed with a comprehensive neuropsychological and behavioral battery. Cortical pattern matching and a region-of-interest analysis, based on Brodmann areas (BAs), were used to map three-dimensional (3-D) profiles of differences in patterns of gray matter volume among groups. RESULTS: Schizophrenia patients had 10% and 11% lower total left and right GM volume than healthy elders (p < .001) and 7% and 5% more than AD patients (p = .06 and ns). Regions that had both significantly less gray matter than control subjects and gray matter volume as low as AD mapped to the cingulate gyrus and orbitofrontal cortex (BA 30, 23, 24, 32, 25, 11). The strongest correlate of gray matter volume in elderly schizophrenia patients, although nonsignificant, was the positive symptom subscale of the Positive and Negative Syndrome Scale, mapping to the right anterior cingulate area (r = .42, p = .06). CONCLUSIONS: The orbitofrontal/cingulate region had low gray matter volume in elderly schizophrenia patients. Neither cognitive impairment nor psychiatric symptoms were significantly associated with structural differences, even if positive symptoms tended to be associated with increased gray matter volume in this area.

Frequency and determinants of unprotected sex among HIV-infected persons: the Swiss HIV cohort study.

BACKGROUND: Access to antiretroviral therapy may have changed condom use behavior. In January 2008, recommendations on condom use for human immunodeficiency virus (HIV)-positive persons were published in Switzerland, which allowed for unprotected sex under well-defined circumstances ("Swiss statement"). We studied the frequency, changes over time, and determinants of unprotected sex among HIV-positive persons. METHODS: Self-reported information on sexual preference, sexual partners, and condom use was collected at semi-annual visits in all participants of the prospective Swiss HIV Cohort Study from April 2007 through March 2009. Multivariable logistic regression models were fit using generalized estimating equations to investigate associations between characteristics of cohort participants and condom use. FINDINGS: A total of 7309 participants contributed to 21,978 visits. A total of 4291 persons (80%) reported sexual contacts with stable partners, 1646 (30%) with occasional partners, and 557 (10%) with stable and occasional partners. Of the study participants, 5838 (79.9%) of 7309 were receiving antiretroviral therapy, and of these, 4816 patients (82%) had a suppressed viral load. Condom use varied widely and differed by type of partner (visits with stable partners, 10,368 [80%] of 12,983; visits with occasional partners, 4300 [88%] of 4880) and by serostatus of stable partner (visits with HIV-negative partners, 7105 [89%] of 8174; visits with HIV-positive partners, 1453 [48%] of 2999). Participants were more likely to report unprotected sex with stable partners if they were receiving antiretroviral therapy, if HIV replication was suppressed, and after the publication of the "Swiss statement." Noninjection drug use and moderate or severe alcohol use were associated with unprotected sex. CONCLUSIONS: Antiretroviral treatment and plasma HIV RNA titers influence sexual behavior of HIV-positive persons. Noninjection illicit drug and alcohol use are important risk factors for unprotected sexual contacts.

Immunization of Persons with HIV Infection and other Secondary Immunodeficiencies

Patients with secondary immunodeficiencies are at a high risk of infection. Currently some of these infections are preventable through specific immunization. Prevention of these diseases can diminish morbidity and mortality amongst these patients. In this review we describe the use of vaccines in persons with secondary immunodeficiencies.

Rehabilitation needs assessment in persons with spinal cord injury following the 2010 earthquake in Haiti: a pilot study using an ICF-based tool.

OBJECTIVE: The aim of this pilot study was to describe problems in functioning and associated rehabilitation needs in persons with spinal cord injury after the 2010 earthquake in Haiti by applying a newly developed tool based on the International Classification of Functioning, Disability and Health (ICF). DESIGN: Pilot study. SUBJECTS: Eighteen persons with spinal cord injury (11 women, 7 men) participated in the needs assessment. Eleven patients had complete lesions (American Spinal Injury Association Impairment Scale; AIS A), one patient had tetraplegia. METHODS: Data collection included information from the International Spinal Cord Injury Core Data Set and a newly developed needs assessment tool based on ICF Core Sets. This tool assesses the level of functioning, the corresponding rehabilitation need, and required health professional. Data were summarized using descriptive statistics. RESULTS: In body functions and body structures, patients showed typical problems following spinal cord injury. Nearly all patients showed limitations and restrictions in their activities and participation related to mobility, self-care and aspects of social integration. Several environmental factors presented barriers to these limitations and restrictions. However, the availability of products and social support were identified as facilitators. Rehabilitation needs were identified in nearly all aspects of functioning. To address these needs, a multidisciplinary approach would be needed. CONCLUSION: This ICF-based needs assessment provided useful information for rehabilitation planning in the context of natural disaster. Future studies are required to test and, if necessary, adapt the assessment.

Risk Factors for tuberculosis among human immunodeficiency virus-infected persons. A case-control study in Belo Horizonte, Minas Gerais, Brazil (1985-1996)

The objective of this study was to identify tuberculosis risk factors and possible surrogate markers among human immunodeficiency virus (HIV)-infected persons. A retrospective case-control study was carried out at the HIV outpatient clinic of the Universidade Federal de Minas Gerais in Belo Horizonte. We reviewed the demographic, social-economical and medical data of 477 HIV-infected individuals evaluated from 1985 to 1996. The variables were submitted to an univariate and stratified analysis. Aids related complex (ARC), past history of pneumonia, past history of hospitalization, CD4 count and no antiretroviral use were identified as possible effect modifiers and confounding variables, and were submitted to logistic regression analysis by the stepwise method. ARC had an odds ratio (OR) of 3.5 (CI 95% - 1.2-10.8) for tuberculosis development. Past history of pneumonia (OR 1.7 - CI 95% 0.6-5.2) and the CD4 count (OR 0.4 - CI 0.2-1.2) had no statistical significance. These results show that ARC is an important clinical surrogate for tuberculosis in HIV-infected patients. Despite the need of confirmation in future studies, these results suggest that the ideal moment for tuberculosis chemoprophylaxis could be previous to the introduction of antiretroviral treatment or even just after the diagnosis of HIV infection.

Revue critique d'instruments pour evaluer la douleur chez les personnes cérébrolésées non communicantes aux soins intensifs [Critical review of instruments to assess pain in the non communicative brain injured persons in intensive care].

The purpose of this review is to critically appraise the pain assessment tools for non communicative persons in intensive care available in the literature and to determine their relevance for those with brain injury. Nursing and medical electronic databases were searched to identify pain tools, with a description of psychometric proprieties, in English and French. Seven of the ten tools were considered relevant and systematically evaluated according to the criteria and the indicators in the following five areas: conceptualisation, target population, feasibility and clinical utility, reliability and validity. Results indicate a number of well designed pain tools, but additional work is necessary to establish their accuracy and adequacy for the brain injured non communicative person in intensive care. Recommendations are made to choose the best tool for clinical practice and for research.

Comparison of the clientele of an anonymous HIV test centre and persons tested in the general population.

This study compares the clientele of a Swiss anonymous test centre with the general population tested. Information was obtained through similar questionnaires submitted to two samples of HIV-tested people aged from 17 to 45 years: the first administered in the context of a general population telephone survey (n = 245) and the second completed during face-to-face interviews of the clientele of an anonymous test centre (n = 250). The test centre sample has higher proportions of younger and single people. Attenders for anonymous testing were more likely to have acquired a new regular partner during the year preceding the interview (48.0% versus 14.4%). These differences remain when controlling for age and gender. Decision to test comes mostly from the respondent's own initiative, but suggestion from a doctor is more frequent in the general population (23.8% versus 0.8%), whereas suggestion from partner or friends is more frequent in the anonymous centre (44.4% versus 3.0%). The anonymous test centre clientele is not different from the general population tested except for the relational situation and origin of decision for testing. The test centre has become a place where the general population finds a response to a situation-specific need for HIV testing.

Risk Factors for Anal Cancer in Persons Infected With HIV: A Nested Case-Control Study in the Swiss HIV Cohort Study.

Although persons infected with human immunodeficiency virus (HIV), particularly men who have sex with men, are at excess risk for anal cancer, it has been difficult to disentangle the influences of anal exposure to human papillomavirus (HPV) infection, immunodeficiency, and combined antiretroviral therapy. A case-control study that included 59 anal cancer cases and 295 individually matched controls was nested in the Swiss HIV Cohort Study (1988-2011). In a subset of 41 cases and 114 controls, HPV antibodies were tested. A majority of anal cancer cases (73%) were men who have sex with men. Current smoking was significantly associated with anal cancer (odds ratio (OR) = 2.59, 95% confidence interval (CI): 1.25, 5.34), as were antibodies against L1 (OR = 4.52, 95% CI: 2.00, 10.20) and E6 (OR = â^?, 95% CI: 4.64, â^?) of HPV16, as well as low CD4+ cell counts, whether measured at nadir (OR per 100-cell/μL decrease = 1.53, 95% CI: 1.18, 2.00) or at cancer diagnosis (OR per 100-cell/μL decrease = 1.24, 95% CI: 1.08, 1.42). However, the influence of CD4+ cell counts appeared to be strongest 6-7 years prior to anal cancer diagnosis (OR for <200 vs. â0/00¥500 cells/μL = 14.0, 95% CI: 3.85, 50.9). Smoking cessation and avoidance of even moderate levels of immunosuppression appear to be important in reducing long-term anal cancer risks.

A Study of the Number, Profile and Progression Routes of Homeless Persons before the Court and in Custody

This study aimed to obtain information on homeless people appearing before the courts and in custody in the Dublin Metropolitan area and to track and to determine how homeless persons progress through the court and prison systems. The overall objective was to provide information the Probation and Welfare Service's processes of policy formation, service development and planning. Findings on the number of homeless offenders, their profile, their progression routes into the criminal justice system and prisoner reintegration are presented. Recommendations are made regarding sentencing policy, agency responsibility for ex-prisoners and appropriate issues for discussion by the Cross Departmental Committee on Homelessness. It is also recommended that drug free units be available across all closed regime prison establishments.This resource was contributed by The National Documentation Centre on Drug Use.
