Background Individuals co-infected with Kaposi’s sarcoma herpesvirus (KSHV) and Human Immunodeficiency Virus (HIV) are at greatly increased risk of developing Kaposi’s sarcoma (KS). The objective of the current analysis is to identify risk cofactors, for KS among HIV-positive individuals. Methods We conducted a case-control study of KS in Cameroon on 161 HIV-positive and 14 HIV-negative cases and 680 HIV-positive and 322 HIV-negative controls. Participants answered a physician-administered questionnaire and provided blood and saliva specimens. Antibodies against KSHV lytic, K8.1, and latent, ORF73, antigens were measured by ELISA to determine KSHV serostatus. Conditional logistic regression was performed to determine multivariate odds ratios (OR) and 95% confidence intervals (CI) for risk factors associated with KS among HIV-positive cases and controls. Results Overall, 98% (158) of HIV-positive cases, 100% (14) of HIV-negative cases, 81% (550) of HIV-positive controls, and 80% (257) of HIV-negative controls were KSHV seropositive. Risk factors for KS among HIV-positive individuals included KSHV seropositivity (OR=9.6; 95% CI 2.9, 31.5), non-use of a mosquito bed net (OR 1.9; 95% CI 1.2, 2.9), minority ethnicity (OR=3.1; 95% CI 1.1, 9.3), treatment from a traditional healer (OR=2.3; 95% CI 1.5, 3.7), history of transfusion (OR=2.4; 95% CI 1.5, 3.9), and family history of cancer (OR=1.9; 95% CI 1.1, 3.1). Conclusion KSHV seroprevalence of ≥80% indicates a high prevalence in the general population in Cameroon. Among HIV-positive individuals, the strong association of KS with non-use of mosquito nets and treatment from traditional healers are compelling findings, consistent with recently reported data from East Africa.
In the United States, undocumented African immigrants living with HIV enter care late, potentially leading to adverse individual and population health outcomes, yet little is known about the specific experiences of HIV diagnosis and linkage to care among this population. We conducted individual, semi-structured interviews with adults who were undocumented African immigrants living with HIV in New York City. Interviews explored perspectives regarding individual, social, institutional, and societal barriers and facilitators of HIV testing and linkage to care. Of 14 participants from 9 different African countries, 9 were women and the median age was 44 years (interquartile range: 42-50). Participants described fear of discovery by immigration authorities as a substantial barrier to HIV testing and linking to initial medical appointments. Actual and perceived structural barriers to both testing and care linkage included difficulty obtaining health insurance and a belief that undocumented immigrants are ineligible for any health services. Participants also expressed reluctance to be tested because of HIV-related stigma within the immigrant communities that they heavily relied on. After diagnosis, however, participants overwhelmingly described a positive role of health and social service providers in facilitating linkage to HIV care. Concerns about immigration status and HIV-related stigma are significant barriers to HIV testing and linkage to care among undocumented African immigrants. Multilevel efforts to reduce stigma and increase awareness of available services could enhance rates of HIV testing and care linkage in this population.
The transition from elementary to secondary school is challenging for all students as a number of environmental, social, psychological, and physiological changes are imposed on them. These challenges often have a significant effect on typical students but may have an even more profound effect on students with Asperger Syndrome (AS) due to the nature of the disability. This article outlines the numerous difficulties that students with AS may encounter during the transition to middle and high school. In addition, a range of specific supports and strategies are offered in order to assist students with AS in making a successful transition.
The Childhood Autism Rating Scale (CARS) was factor analyzed to determine if distinct and independent "subgroups" of symptoms could be derived, which would be consistent with the current multidimensional theory and nosology for autism. To address this issue, the CARS was factor analyzed for a sample of 90 children with diagnoses of either autism or PDDNOS, based on DSM-III-R diagnostic criteria. Five factors emerged: Social Communication, Emotional Reactivity, Social Orienting, Cognitive and Behavioral Consistency, and Odd Sensory Exploration. Factor-based scales were created. These factor-based scales were demonstrated to distinguish subjects with autism from subjects with PDDNOS and nonautistic subjects. Factor-based scores were examined to determine the degree to which they were associated with individual differences (such as age, IQ, gender, history of regression, and history of abnormal EEGs) among children with pervasive developmental disorders (PDDs). The application of these distinct and independent factors may have important clinical and research implications. The generation of factor-based scales may provide information on the nature of the individual differences that are thought to be present among children with autism. Additionally, the use of factor-based scale scores may increase the sensitivity of the CARS for identifying younger and/or higher functioning individuals within the PDD spectrum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
