    A clinical AIDS case definition is needed for surveillance in countries where the CDC case definition is not practical. To derive such a definition, we compared 110 HIV-seropositive and 135 randomly selected HIV-seronegative adult medical-ward inpatients in Brazil. Multivariate analysis of clinical signs and symptoms and simple diagnoses resulted in a discriminant function with sensitivity of 89% and specificity of 96% in predicting for AIDS. These data were the empirical basis for a clinical definition of AIDS in adults drafted in a Caracas, Venezuela, workshop sponsored by the Pan American Health Organization. The revised "Caracas" definition presented here requires a positive HIV serology, the absence of cancer or other cause of immunosuppression, plus > or = 10 cumulative points, as follows: Kaposi's sarcoma (10 points); extrapulmonary/noncavitary pulmonary tuberculosis (10); oral candidiasis or hairy leukoplakia (5); cavitary pulmonary/unspecified tuberculosis (5); herpes zoster < 60 years of age (5); CNS dysfunction (5); diarrhea > or = 1 month (2); fever > or = 1 month (2); cachexia or > 10% weight loss (2); asthenia > or = 1 month (2); persistent dermatitis (2); anemia, lymphopenia, or thrombocytopenia (2); persistent cough or any pneumonia except TB (2); and lymphadenopathy > or = 1 cm at > or = 2 noninguinal sites for > or = 1 month (2). This definition has a sensitivity of 95% and a specificity of 100% (91% without HIV serology) when applied to the Brazilian patients in this study. The Caracas definition has been adopted by Brazil, Honduras, and Surinam, and is in validation elsewhere. The use of a reasonably sensitive and specific case definition commensurate with available diagnostic resources should facilitate AIDS surveillance in developing countries. PMID:1453332

    Association studies have shown and continue to show a substantial amount of success in identifying links between multiple single nucleotide polymorphisms (SNPs) and phenotypes. These studies are also believed to provide insights toward identification of new drug targets and therapies. Albeit of all the success, challenges still remain for applying and prioritizing these associations based on available biological knowledge. Along with single variant association analysis, genetic interactions also play an important role in uncovering the etiology and progression of complex traits. For gene-gene interaction analysis, selection of the variants to test for associations still poses a challenge in identifying epistatic interactions among the large list of variants available in high-throughput, genome-wide datasets. Therefore in this study, we propose a pipeline to identify interactions among genetic variants that are associated with multiple phenotypes by prioritizing previously published results from main effect association analysis (genome-wide and phenome-wide association analysis) based on a-priori biological knowledge in AIDS Clinical Trials Group (ACTG) data. We approached the prioritization and filtration of variants by using the results of a previously published single variant PheWAS and then utilizing biological information from the Roadmap Epigenome project. We removed variants in low functional activity regions based on chromatin states annotation and then conducted an exhaustive pairwise interaction search using linear regression analysis. We performed this analysis in two independent pre-treatment clinical trial datasets from ACTG to allow for both discovery and replication. Using a regression framework, we observed 50,798 associations that replicate at p-value 0.01 for 26 phenotypes, among which 2,176 associations for 212 unique SNPs for fasting blood glucose phenotype reach Bonferroni significance and an additional 9,970 interactions for high

    Objectives It is uncertain whether HIV-1 antiretroviral exposure and clinical response varies between males and females or different race/ethnic groups. We describe ritonavir-enhanced atazanavir pharmacokinetics in relation to virological failure, safety and tolerability in treatment-naive individuals to investigate potential differences. Methods Plasma samples were collected from participants in AIDS Clinical Trials Group Study A5202 for measurement of antiretroviral concentrations. Individual estimates of apparent oral clearance of atazanavir (L/h) were calculated from a one-compartment model and divided into tertiles as slow (<7), middle (7 to <9; reference group) and fast (≥9). Associations between atazanavir clearance and clinical outcomes were estimated with a hazard ratio (HR) from Cox proportional hazards models. Interactions between atazanavir clearance and sex, race/ethnicity and NRTIs were investigated for each of the outcomes. Results Among 786 participants, average atazanavir clearance was slower in females (n = 131) than males (n = 655). Atazanavir clearance was associated with time to virological failure (P = 0.053) and this relationship differed significantly by sex (P = 0.003). Females in the fast atazanavir clearance group had shorter time to virological failure (HR 3.49; 95% CI 1.24–9.84) compared with the middle (reference) atazanavir clearance group. Among males, the slow atazanavir clearance group had a higher risk of virological failure (HR 2.10; 95% CI 1.16–3.77). Conclusions Atazanavir clearance differed by sex. Females with fast clearance and males with slow clearance had increased risk of virological failure. PMID:25159623

    Objective To report on the incidence of clinical- and laboratory-defined pancreatitis in HIV-1–infected individuals treated with antiretrovirals (ARVs). Methods Pancreatitis incidence rates were calculated based on a Poisson distribution for subjects enrolled in 1 or more of 20 Adult AIDS Clinical Trials Group studies from October 1989 through July 1999. Results A total of 8451 subjects were enrolled. The overall pancreatitis rates were 0.61 per 100 person-years (PYs) clinical and 2.23 per 100 PYs clinical/laboratory. Pancreatitis rates for single, dual, and triple nucleoside reverse transcriptase inhibitors (NRTIs) were similar. Rates of pancreatitis in didanosine (ddI) arms seemed to be dose dependent. Pancreatitis rates in ddI/hydroxyurea (HU) arms were not significantly different from the rates for ddI alone. Overall pancreatitis rates for ddI/stavudine (d4T) trials were high at 4.16 per 100 PYs clinical and 6.25 per 100 PYs clinical/laboratory. The highest rates were seen with the combination of indinavir (IDV)/ddI/d4Twith or without HU. Conclusions The combination of NRTIs and definition has an impact on the incidence of pancreatitis. Standardization of definition and more comprehensive evaluations are needed to determine how much of this pancreatitis is directly caused by ARVs and how much is attributable to preexisting comorbidities and other known risk factors.

    Controversies regarding the benefits of breast cancer screening programs have led to the promotion of new strategies taking into account individual preferences, such as decision aid. The aim of this study was to assess the impact of a decision aid leaflet on the participation of women invited to participate in a national breast cancer screening program. This Randomized, multicentre, controlled trial. Women aged 50 to 74 years, were randomly assigned to receive either a decision aid or the usual invitation letter. Primary outcome was the participation rate 12 months after the invitation. 16 000 women were randomized and 15 844 included in the modified intention-to-treat analysis. The participation rate in the intervention group was 40.25% (3174/7885 women) compared with 42.13% (3353/7959) in the control group (p = 0.02). Previous attendance for screening (RR = 6.24; [95%IC: 5.75-6.77]; p < 0.0001) and medium household income (RR = 1.05; [95%IC: 1.01-1.09]; p = 0.0074) were independently associated with attendance for screening. This large-scale study demonstrates that the decision aid reduced the participation rate. The decision aid activate the decision making process of women toward non-attendance to screening. These results show the importance of promoting informed patient choices, especially when those choices cannot be anticipated. PMID:26883201

    To develop a computer-aided diagnostic scheme by using an artificial neural network (ANN) combined with tumor markers for diagnosis of hepatic carcinoma (HCC) as a clinical assistant method. 140 serum samples (50 malignant, 40 benign and 50 normal) were analyzed for α-fetoprotein (AFP), carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA), sialic acid (SA) and calcium (Ca). The five tumor marker values were then used as ANN inputs data. The result of ANN was compared with that of discriminant analysis by receiver operating characteristic (ROC) curve (AUC) analysis. The diagnostic accuracy of ANN and discriminant analysis among all samples of the test group was 95.5% and 79.3%, respectively. Analysis of multiple tumor markers based on ANN may be a better choice than the traditional statistical methods for differentiating HCC from benign or normal.

    This consensus document was prepared by an expert panel of the Grupo de Estudio de Sida (GESIDA [Spanish AIDS Study Group]) and the Plan Nacional sobre el Sida (PNS [Spanish National AIDS Plan]). The document updates current guidelines on the treatment of tuberculosis (TB) in HIV-infected individuals contained in the guidelines on the treatment of opportunistic infections published by GESIDA and PNS in 2008. The document aims to facilitate the management and treatment of HIV-infected patients with TB in Spain, and includes specific sections and recommendations on the treatment of drug-sensitive TB, multidrug-resistant TB, and extensively drug-resistant TB, in this population. The consensus guidelines also make recommendations on the treatment of HIV-infected patients with TB in special situations, such as chronic liver disease, pregnancy, kidney failure, and transplantation. Recommendations are made on the timing and initial regimens of antiretroviral therapy in patients with TB, and on immune reconstitution syndrome in HIV-infected patients with TB who are receiving antiretroviral therapy. The document does not cover the diagnosis of TB, diagnosis/treatment of latent TB, or treatment of TB in children. The quality of the evidence was evaluated and the recommendations graded using the approach of the Grading of Recommendations Assessment, Development and Evaluation Working Group. PMID:23541879

    1996-05-01

    The Communications Decency Act (CDA), a section of the 1996 telecommunications reform law, bans indecent and patently offensive expression from all online systems available to those under the age of 18. AIDS organizations and the American Civil Liberties Union (ACLU) filed suit in U.S. District Court in Philadelphia, PA,to challenge the law. The ACLU contends that the CDA law is unconstitutional because it criminalizes expression that is protected by the First Amendment, and violates constitutional rights to privacy. The CDA also would impede dissemination of HIV prevention information, according to AIDS online services. Operators of these electronic information systems state that providing explicit language about safe sexual practices is essential if teenagers are to understand how to prevent HIV infection. Additionally, content providers argue that it is almost impossible to know what text or images must be censored in order to avoid government prosecution. Expert witnesses testifying for the U.S. Government stated that there are means available to purge Internet sites of materials that might be regarded as indecent. The ACLU recommends utilizing a software package that would enable parents to control their children's Internet access without requiring broad censorship. PMID:11363465

    Infrastructure for conducting neurological research in resource-limited settings (RLS) is limited. The lack of neurological and neuropsychological (NP) assessment and normative data needed for clinical interpretation impedes research and clinical care. Here, we report on ACTG 5271, which provided neurological training of clinical site personnel and collected neurocognitive normative comparison data in diverse settings. At ten sites in seven RLS countries, we provided training for NP assessments. We collected normative comparison data on HIV- participants from Brazil (n = 240), India (n = 480), Malawi (n = 481), Peru (n = 239), South Africa (480), Thailand (n = 240), and Zimbabwe (n = 240). Participants had a negative HIV test within 30 days before standardized NP exams were administered at baseline and 770 at 6 months. Participants were enrolled in eight strata, gender (female and male), education (<10 and ≥10 years), and age (<35 and ≥35 years). Of 2400 enrolled, 770 completed the 6-month follow-up. As expected, significant between-country differences were evident in all the neurocognitive test scores (p < 0.0001). There was variation between the age, gender, and education strata on the neurocognitive tests. Age and education were important variables for all tests; older participants had poorer performance, and those with higher education had better performance. Women had better performance on verbal learning/memory and speed of processing tests, while men performed better on motor tests. This study provides the necessary neurocognitive normative data needed to build infrastructure for future neurological and neurocognitive studies in diverse RLS. These normative data are a much-needed resource for both clinicians and researchers. PMID:26733457

    Objective Prior studies have found that early HIV protease inhibitors (PIs) contribute to glucose dysregulation. Few randomized trials have evaluated glucose indices in antiretroviral-naïve subjects on newer antiretroviral therapy (ART). Methods A5224s was a substudy of A5202, a prospective trial of 1857 ART-naïve participants randomized to blinded abacavir-lamivudine (ABC/3TC) or tenofovir DF-emtricitabine (TDF/FTC) with open-label efavirenz (EFV) or atazanavir-ritonavir (ATV/r). Analyses used 2-sample t-tests, Spearman correlation coefficients and linear regression. Results A5224s included 269 non-diabetic subjects: 85% male, 47% white non-Hispanic, baseline median age 38 years, HIV-1 RNA 4.6 log10 copies/mL and CD4 233 cells/μL. Overall, significant 96-week increases occurred in fasting glucose, insulin, and the homeostatic model assessment of insulin resistance (HOMA-IR), p≤0.004. Assignment to EFV (vs ATV/r) resulted in significantly greater glucose increase (mean difference 4.4; 95% CI 1.3, 7.5 mg/dL; p=0.006) but not insulin or HOMA-IR (p≥0.72). Glucose indices were not significantly different between ABC/3TC or TDF/FTC arms, p≥0.18. Significant correlations were detected between changes in glucose indices and changes in body mass index; all r≥0.23, p≤0.001. In multivariable analyses, in addition to the EFV effect, higher baseline HIV-1 RNA, and greater BMI change were significant independent factors associated with greater glucose increase. Conclusions Changes in glucose metabolism were not significantly different between TDF/FTC- and ABC/3TC-based regimens. A small but significantly greater increase in glucose was observed in those assigned to EFV. As glucose dysregulation may increase with time on ART, longer term studies will be needed to further clarify the clinical significance of these findings. PMID:24637543

    OBJECTIVE: To estimate median survival and changes in survival in patients diagnosed as having AIDS. DESIGN: Prospective observational study. SETTING: Clinics in two large London hospitals. SUBJECTS: 2625 patients with AIDS seen between 1982 and July 1995. MAIN OUTCOME MEASURES: Survival, estimated using lifetable analyses, and factors associated with survival, identified from Cox proportional hazards models. RESULTS: Median survival (20 months) was longer than previous estimates. The CD4 lymphocyte count at or before initial AIDS defining illness decreased significantly over time from 90 x 10(6)/1 during 1987 or earlier to 40 x 10(6)/1 during 1994 and 1995 (P < 0.0001). In the first three months after diagnosis, patients in whom AIDS was diagnosed after 1987 had a much lower risk of death (relative risk 0.44, 95% confidence interval 0.22 to 0.86; P = 0.017) than patients diagnosed before 1987. When the diagnosis was based on oesophageal candidiasis or Kaposi's sarcoma, patients had a lower risk of death than when the diagnosis was based on Pneumocystis carinii pneumonia (0.21 (0.07 to 0.59). P = 0.0030 and 0.37 (0.16 to 0.83), P = 0.016). Three months after AIDS diagnosis, the risk of death was similar in patients whose diagnosis was made after and before 1987 (1.02 (0.79 to 1.31), P = 0.91). There were no differences in survival between patients diagnosed during 1988-90, 1991-3, or 1994-5. CONCLUSIONS: In later years, patients were much more likely to survive their initial illness, but long term survival has remained poor. The decrease in CD4 lymphocyte count at AIDS diagnosis indicates that patients are being diagnosed as having AIDS at ever more advanced stages of immunodeficiency. PMID:9040386

    Crack cocaine, a smokable form of cocaine hydrochloride, is now widely available in American inner cities. Reports of high rates of unprotected sexual activity among crack users, coupled with reports of high rates of sexually transmitted diseases (STDs), have raised fears that this population of drug users may soon be contracting and disseminating sexually transmitted HIV. In a study of 205 black adolescent crack users conducted in Oakland and San Francisco, California, 101 respondents (49% of the sample) who reported using crack in combination with sexual activity were examined. Those respondents who reported having a history of one or more STD were compared using discriminant analysis (DA). A successful discrimination (canonical correlation = 0.61, p = 0.000) identified five variables that distinguished those with a STD history from those with no STD history: gender (being female) (p = 0.000), frequency of marijuana use (p = 0.005), response to the question; "Do you plan for sex or does it just happen?" (p = 0.002), response to the statement, "I use drugs to get away from my problems" (0.029), and response to the question, "Do you agree that sex doesn't feel as good when you use a condom?" (p = 0.006). The selection of these variables was thought to represent an underlying passivity in the way that crack users who combine crack use with sex approach sexual activity. PMID:2386974

    2005-01-01

    Background HIV/AIDS-related stigma and discrimination are significant determinants of HIV transmission in the Caribbean island nation of Trinidad and Tobago (T&T), where the adult HIV/AIDS prevalence is 2.5%. T&T is a spiritually-aware society and over 104 religious groups are represented. This religious diversity creates a complex social environment for the transmission of a sexually transmitted infection like HIV/AIDS. Religious leaders are esteemed in T&T's society and may use their position and frequent interactions with the public to promote HIV/AIDS awareness, fight stigma and discrimination, and exercise compassion for people living with HIV/AIDS (PWHA). Some religious groups have initiated HIV/AIDS education programs within their membership, but previous studies suggest that HIV/AIDS remains a stigmatized infection in many religious organizations. The present study investigates how the perception of HIV/AIDS as a sexually transmitted infection impacts religious representatives' incentives to respond to HIV/AIDS in their congregations and communities. In correlation, the study explores how the experiences of PWHA in religious gatherings impact healing and coping with HIV/AIDS. Methods Between November 2002 and April 2003, in-depth interviews were conducted with 11 religious representatives from 10 Christian, Hindu and Muslim denominations. The majority of respondents were leaders of religious services, while two were active congregation members. Religious groups were selected based upon the methods of Brathwaite. Briefly, 26 religious groups with the largest followings according to 2000 census data were identified in Trinidad and Tobago. From this original list, 10 religious groups in Northwest Trinidad were selected to comprise a representative sample of the island's main denominations. In-depth interviews with PWHA were conducted during the same study period, 2002–2003. Four individuals were selected from a care and support group located in Port of Spain

METHODS. Sixteen health departments collected death certificates for 55,186 persons with AIDS whose deaths occurred through 1991. Place of death was categorized as hospital, residence, hospice or nursing home, and other. RESULTS. The percentage of AIDS deaths at hospital facilities decreased from 92% in 1983 to 57% in 1991. In 1988, 23% of deaths occurred at home or in hospices and nursing homes. This trend was more evident among men, Whites, and men who had sex with men; less so among persons with other modes of exposure; and not at all among injecting drug users and children with perinatally acquired AIDS. Place of death varied by geographic location, with the greatest percentage of hospital deaths in the Northeast (91%) and the greatest percentage of at-home deaths in the West (27%). CONCLUSIONS. The percentage of AIDS deaths at home or in hospices and nursing homes has increased since 1983. These trends may reflect changes in hospital use for end-stage HIV infection. Decreasing hospitalization and increasing outpatient services and home care will decrease costs and may allow HIV-infected persons improved social support. PMID:8214234

    OBJECTIVE. This study reports the results of a behavior change intervention offered to women at high risk for human immunodeficiency virus (HIV) infection seen in an urban primary health care clinic. METHODS. Participants were 197 women randomly assigned to either an HIV/acquired immunodeficiency syndrome (AIDS) risk reduction group or a comparison group. Women in the HIV/AIDS intervention group attended five group sessions focusing on risk education; skills training in condom use, sexual assertiveness, problem solving, and risk trigger self-management; and peer support for change efforts. Women in the comparison group attended sessions on health topics unrelated to AIDS. RESULTS. At the 3-month follow-up, women in the HIV/AIDS intervention group had increased in sexual communication and negotiation skills. Unprotected sexual intercourse had declined significantly and condom use had increased from 26% to 56% of all intercourse occasions. Women in the comparison group showed no change. CONCLUSIONS. Socially disadvantaged women can be assisted in reducing their risk of contracting HIV infection. Risk reduction behavior change interventions should be offered routinely in primary health care clinics serving low-income and high-risk patients. PMID:7998630

    The aim of this paper was to develop a consensus on clinical recommendations for health care assistance for women with HIV infection. To this end, a panel of experts, appointed by the Secretariat of the National AIDS Plan and GeSIDA was assembled, that included internal medicine physicians with expertise in the field of HIV infection, gynecologists, pediatricians and psychologists, with two members of the panel acting as coordinators. Scientific information was reviewed in publications and conference reports up to October 2012. In keeping with the criteria of the Infectious Disease Society of America, two levels of evidence were applied to support the proposed recommendations: the strength of the recommendation according to expert opinion (A, B, C) and the level of empirical evidence (I, II, III), already used in previous documents from SPNS/GESIDA. Multiple recommendations are provided for the clinical management of women with HIV infection, considering both the diagnostic and possible therapeutic strategies. This document presents recommendations for the treatment of women with HIV infection. This must be multidisciplinary, taking into account the differences that can be found in the diagnosis, development of disease and treatment between men and women. PMID:23931832

    Introduction Every person has certain features that make them radically distinct from others. One such feature is lip prints. Lip prints remain the same throughout life and are uninfluenced by injuries, diseases, or environmental changes. Different individuals have specific blood groups according to the various antigen–antibody reactions in their bloodstream. Aim To determine the distribution of different patterns of lip prints among subjects having different ABO and Rh blood groups. Objective To determine the correlation between respective characteristics of subjects. Methodology In this study, lip prints were obtained from 122 subjects (62 males and 60 females), and associated blood-group matching was performed to determine the predominant lip print type and to determine any correlation between lip print types and blood groups. Tsuchihashi’s classification of type I (complete vertical grooves), type I′ (incomplete vertical grooves), type II (forking grooves), type III (intersecting grooves), type IV (reticular grooves), and type V (indeterminate grooves) was used to compare with the ABO and Rh blood grouping systems. Result No correlation was found between lip prints and blood groups. Conclusion No significant correlation exists between blood group and lip prints. Lip prints play a vital role in identification because they are unique. PMID:25382951

    Benevento, A L

    1998-01-01

    Promoting safety in the workplace has been attempted in a variety of ways. Increasingly, industries are using groups such as safety teams and quality circles to promote worker safety. Group influences on individual behavior and attitudes have long been studied in the social psychology literature, but the theories have not been commonly found outside the psychology arena. This paper describes the group theories of group polarization, risky shift, social loafing, groupthink and team think and attempts to apply these theories to existing studies that examine work group influences on safety. Interesting parallels were found but only one study examined group influences as their primary focus of research. Since groups are increasingly used for safety promotion, future research on safety that studies group influences with respect to current group theories is recommended. PMID:24441299

    Background Inattention to symptoms of mental disorders and substance abuse in patients with HIV/AIDS and other at-risk groups, may lead to irreversible damages. The purpose of this study was to compare the psychopathological dimensions in substance abusers with and without HIV/AIDS and healthy matched groups. Methods In a cross-sectional and analytical study, selected samples (by available, consecutive, and objective methods) were 43 HIV-positive substance abusers, 49 HIV negative substance abusers under methadone maintenance therapy (MMT) in the counseling clinic of Behavioral Diseases and Addiction Abandonment, and 45 ordinary individuals. All of them were evaluated by matched confounding variables via Symptom Checklist-90-Revised (SCL-90-R). Findings Results indicated a significant difference between these groups in the Global Severity Index (GSI), Positive Symptom Distress Index (PSDI), and Positive Symptom Total (PST) (P < 0.001). Two by two the comparison of the three groups from psychopathological dimensions revealed that substance abusers with HIV/AIDS persistently suffer more mental problems in all dimensions compared with healthy individuals (P < 0.05). In addition, in comparison with HIV negative substance abusers, they also suffer more mental problems in other dimensions, including somatization, interpersonal sensitivity, depression, anxiety, phobia, and psychoticism (P < 0.05). Yet, the difference in paranoid ideation, hostility, and obsessive-compulsive cases was insignificant. Two by two, the comparison between healthy individuals and substance abusers without HIV/AIDS showed higher levels of depression and psychoticism in substance abusers (P < 0.05), but no difference in other dimensions. Conclusion Comorbidity of substance abuse and HIV diagnosis intensify mental disorder symptoms. Moreover, lack of prevention and implementation of appropriate psychological and psychiatric interventions after substance abuse and HIV lead to extended establishment

    Objective To compare the effect initiating different antiretroviral therapy (ART) regimens have on weight, body mass index (BMI), and lean body mass (LBM) and explore how changes in body composition are associated with bone mineral density (BMD). Methods A5224s was a substudy of A5202, a prospective trial of 1857 ART-naïve participants randomized to blinded abacavir-lamivudine (ABC/3TC) or tenofovir DF-emtricitabine (TDF/FTC) with open-label efavirenz (EFV) or atazanavir-ritonavir (ATV/r). All subjects underwent dual-energy absorptiometry (DXA) and abdominal CT for body composition. Analyses used 2-sample t-tests and linear regression. Results A5224s included 269 subjects: 85% male, 47% white non-Hispanic, median age 38 years, HIV-1 RNA 4.6 log10 copies/mL, and CD4 233 cells/µL. Overall, significant gains occurred in weight, BMI, and LBM at 96 weeks post randomization (all p<0.001). Assignment to ATV/r (vs EFV) resulted in significantly greater weight (mean difference 3.35 kg) and BMI gain (0.88 kg/m2; both p=0.02), but not LBM (0.67 kg; p=0.15), while ABC/3TC and TDF/FTC were not significantly different (p≥0.10). In multivariable analysis, only lower baseline CD4 count and higher HIV-1 RNA were associated with greater increase in weight, BMI, or LBM. In multivariable analyses, increased LBM was associated with an increased hip BMD. Conclusions ABC/3TC vs. TDF/FTC did not differ in change in weight, BMI, or LBM; ATV/r vs. EFV resulted in greater weight and BMI gain but not LBM. A positive association between increased LBM and increased hip BMD should be further investigated through prospective interventional studies to verify the impact of increased LBM on hip BMD.

    The acquired immunodeficiency syndrome (AIDS) in humans was one of the chronic infections caused by human immunodeficiency virus (HIV), and the interactions between viral infection and mitochondrial energetic implicated that mitochondrial DNA (mtDNA) variation(s) may effect genetic susceptibility to AIDS. Thus, to illustrate the maternal genetic structure and further identify whether mtDNA variation(s) can effect HIV infection among southwest Chinese AIDS group, the whole mtDNA control region sequences of 70 AIDS patients and 480 health individuals from southwest China were analyzed here. Our results indicated the plausible recent genetic admixture results of AIDS group; comparison of matrilineal components between AIDS and matched Han groups showed that mtDNA haplogroup A (p = 0.048, OR = 3.006, 95% CI = 1.109-8.145) has a significant higher difference between the two groups; further comparison illustrated that mtDNA mutations 16,209 (p = 0.046, OR = 2.607, 95% CI = 0.988-6.876) and 16,319 (p = 0.009, OR = 2.965, 95% CI = 1.278-6.876) have significant differences between AIDS and matched control groups, and both of which were the defining variations of mtDNA haplogroup A, they further confirmed that mtDNA haplogroup A may confer genetic susceptibility to AIDS. Our results suggested that haplogroup A may confer a genetic susceptibility to AIDS group from Southwest China. PMID:25431816

    Background Detectable HIV-1 in body compartments can lead to transmission and antiretroviral resistance. Although sex differences in viral shedding have been demonstrated, mechanisms and magnitude are unclear. We compared RNA levels in blood, genital-secretions and saliva; and drug resistance in plasma and genital-secretions of men and women starting/changing antiretroviral therapy (ART) in the AIDS Clinical Trials Group (ACTG) 5077 study. Methods Blood, saliva and genital-secretions (compartment fluids) were collected from HIV-infected adults (≥13 years) at 14 United-States sites, who were initiating or changing ART with plasma viral load (VL) ≥2,000 copies/mL. VL testing was performed on all compartment fluids and HIV resistance genotyping on plasma and genital-secretions. Spearman rank correlations were used to evaluate concordance and Fisher’s and McNemar’s exact tests to compare VL between sexes and among compartments. Results Samples were available for 143 subjects; 36% treated (23 men, 29 women) and 64% ‘untreated’ (40 men, 51 women). RNA detection was significantly more frequent in plasma (100%) than genital-secretions (57%) and saliva (64%) (P<0.001). A higher proportion of men had genital shedding versus women (78% versus 41%), and RNA detection was more frequent in saliva versus genital-secretions in women when adjusted for censoring at the limit of assay detection. Inter-compartment fluid VL concordance was low in both sexes. In 22 (13 men, 9 women) paired plasma-genital-secretion genotypes from treated subjects, most had detectable resistance in both plasma (77%) and genital-secretions (68%). Resistance discordance was observed between compartments in 14% of subjects. Conclusions HIV shedding and drug resistance detection prior to initiation/change of ART in ACTG 5077 subjects differed among tissues and between sexes, making the gold standard blood-plasma compartment assessment not fully representative of HIV at other tissue sites

    Community involvement is increasingly identified as a "critical enabler" of an effective HIV/AIDS response. We explore pathways between community participation and HIV prevention, treatment and impact mitigation in Zimbabwe, reviewing six qualitative studies in Manicaland. These find that community group membership is often (not always) associated with decreased HIV incidence, reduced stigma and improved access to some services, particularly amongst women. Participation in formal community groups (e.g., church or women's groups) and informal local networks (e.g., neighbours, families) provides opportunities for critical dialogue about HIV/AIDS, often facilitating renegotiation of harmful social norms, sharing of previously hidden personal experiences of HIV/AIDS, formulation of positive action plans and solidarity to action them. However, implementation of new plans and insights is constrained by poverty, social uncertainty and poor service delivery. Furthermore, dialogue may have negative effects, spreading false information and entrenching negative norms. The extent that formal groups and informal networks facilitate externally imposed HIV/AIDS interventions varies. They potentially provide vital practical and emotional support, facilitating service access, treatment adherence and AIDS care. However, they may sometimes play a negative role in prevention activities, challenging stereotypes about sexuality or gender. There is an urgent need for greater recognition of the role of indigenous community groups and networks, and the inclusion of "strengthening local responses" as a key element of interventions and policy. Such efforts require great sensitivity. Heavy-handed external interference in complex indigenous relationships risks undermining the localism and bottom-up initiative and activism that might be central to their effectiveness. Cautious efforts might seek to enhance the potentially beneficial effects of groups, especially for women, and limit potentially

    As the number of children orphaned by AIDS (Acquired Immunodeficiency Syndrome) has reached 17.3 million, most living in resource-poor settings, interest has grown in identifying and evaluating appropriate care arrangements for them. In this study, we describe the community-based family-style group homes (‘group homes’) in rural China. Guided by an ecological framework of children’s wellbeing, we conducted a series of ethnographic observations, in-depth interviews and group discussions in the rural areas of Henan Province, which has been severely impacted by the AIDS endemic through commercial blood collection. Based on our observations and discussions, group homes appear to provide stable and safe living environments for children orphaned by AIDS. Adequate financial support from non-government organizations (NGOs) as well as the central and provincial governments has ensured a low child–caregiver ratio and attention to the basic needs of the children at group homes. The foster parents were selected from the local community and appear to have adequate qualifications and dedication. They receive a monthly stipend, periodical evaluation and parenting consultation from supporting NGOs. The foster parents and children in the group homes have formed strong bonds. Both children and foster parents reported positively on health and education. Characteristics of community-based group homes can be replicated in other care arrangements for AIDS orphans in resource-poor settings for the optimal health outcomes of those vulnerable children. We also call for capacity building for caregivers and communities to provide sustainable and supportive living environment for these children. PMID:25124083

    This article explores the contribution of self-help/mutual aid groups to mental well-being. Self-help/mutual aid groups are self-organising groups where people come together to address a shared a health or social issue through mutual support. They are associated with a range of health and social benefits, but remain poorly understood. This article draws on data from stage one of ESTEEM, a project which runs from 2010 to 2013. Stage one ran from 2010 to 2011 and involved participatory, qualitative research carried out in two UK sites. Twenty-one groups were purposively selected to include a range of focal issues, longevity, structures and ethnic backgrounds. Researchers carried out 21 interviews with group coordinators and twenty group discussions with members to explore the groups' purpose, nature and development. Preliminary analysis of the data suggested that mental well-being was a common theme across the groups. Subsequently the data were re-analysed to explore the groups' contribution to mental well-being using a checklist of protective factors for mental well-being as a coding framework. The findings showed that groups made a strong contribution to members' mental well-being by enhancing a sense of control, increasing resilience and facilitating participation. Group members were uplifted by exchanging emotional and practical support; they gained self-esteem, knowledge and confidence, thereby increasing their control over their situation. For some groups, socio-economic factors limited their scope and threatened their future. The article provides an evidence-base which illustrates how self-help/mutual aid groups can enhance mental well-being. If supported within a strategy for social justice, these groups enable people with varied concerns to develop a tailored response to their specific needs. The authors suggest that policy-makers engage with local people, investing in support proportionate to the needs of different populations, enabling them to develop

    Purpose ALLRT is a longitudinal cohort study of HIV-infected subjects prospectively randomized into selected clinical trials for antiretroviral (ARV) treatment-naïve and ARV treatment-experienced individuals conducted by the AIDS Clinical Trials Group (ACTG). We describe the rationale, design, and baseline characteristics of the ALLRT cohort and its potential to address important research questions related to ARV therapy. Method Standardized visits occur every 16 weeks to evaluate long-term clinical, virologic, and immunologic outcomes associated with ARV treatment. Results A total of 4,371 subjects enrolled in ALLRT from January 2000 through June 2007. Of these, 3,146 (72%) were ARV naïve at parent study entry (18% female, 44% white, 32% black, 21% Hispanic; median age 37 years, CD4 count 218 cells/μL, follow-up 3.6 years; 343 [11%] followed ≥8 years) and 1,225 (28%) were treatment experienced (13% female, 59% white, 20% black, 17% Hispanic; median age 42 years, CD4 count 325 cells/μL, follow-up 5.7 years). Conclusions ALLRT provides the opportunity to understand long-term ramifications of therapeutic ARV choices and determine whether these vary by treatment regimen, timing of treatment initiation, or treatment changes over long-term follow-up. Investigations based on uniform data and specimen collection in the context of randomized ARV treatments will be critical to developing more successful long-term therapeutic strategies for HIV treatment.

    2010-01-01

    This paper presents the findings of an exploratory study to investigate the challenges faced by people living with HIV/AIDS (PLWHA) in communities in Cape Town, South Africa. The primary goal of the study was to gather data to inform the adaptation of a group risk reduction intervention to the South African context. Qualitative methods were used to examine the experiences of PLWHA. Eight focus group discussions (FGDs) were conducted with 83 HIV-positive participants and 14 key informants (KIs) involved in work with PLWHA were interviewed. Findings revealed that AIDS-related stigma was still pervasive in local communities. This was associated with the difficulty of disclosure of their status for fear of rejection. Also notable was the role of risky behaviours such as lack of condom use and that PLWHA considered their HIV/AIDS status as secondary to daily life stressors like poverty, unemployment, and gender-based violence. These findings have implications for the adaptation or development of behavioural risk reduction interventions for PLWHA. PMID:21490904

    2011-01-01

    Objective Children can be the only persons present in an emergency situation. Aim of the study was to evaluate the effects of a first aid course for 4-5-year-old kindergarten children given by a first aid instructor and kindergarten teachers. Methods A mixed methods approach using both quantitative and qualitative methods was used to investigate the effects of teaching first aid in the kindergarten in the present study. 10 kindergarten children at the age of 4-5 years were included in a pilot-study, 5 girls and 5 boys. Three of them were four years and seven were five years old. Two months after completion of the first aid course children were tested in a scenario where the children had to provide first aid to an unconscious victim after a cycle accident. The next seven months the children were followed by participant observation. Results The findings suggest that 4-5-year-old children are able to learn and apply basic first aid. Tested two months after course completion 70% of the children assessed consciousness correctly and knew the correct emergency telephone number; 60% showed correct assessment of breathing and 40% of the participants accomplished the other tasks (giving correct emergency call information, knowledge of correct recovery position, correct airway management) correctly. Many of the children showed their capabilities to do so in a first aid scenario although some participants showed fear of failure in the test scenario. In an informal group testing most of these children could perform first aid measures, too. Teaching first aid also lead to more active helping behaviour and increased empathy in the children. Conclusion Kindergarten children aged 4-5 years can learn basic fist aid. First aid training should start in the kindergarten. PMID:21356047

    The HIV and STIs epidemic in China has had a significant impact among China's ethnic minorities. However, the official traditional approach, which has used an anti-epidemic social campaign, has not paid any attention to the diversity of cultural backgrounds of the many ethnic minority groups. This study carried out in Sichuan Province is the first to explore how to use cultural resources for developing an effective strategy for promoting HIV prevention in different cultural groups in China. One hundred and fifty male volunteers drawn from the Yi (50), Tibetan (50) and majority Han (50) cultural groups were assigned to a direct training programme. After training, these participants spread safe sex messages to other contacts who became an indirect peer diffusion group. A third group of 150 male volunteers from the same three cultural groups but from another relatively comparable community acted as controls. Each participant was interviewed before and after the intervention to assess knowledge, attitudes and behavioural intentions regarding HIV/AIDS prevention. The study examined the cultural appropriateness and effectiveness of peer-led health message diffusion in promoting condom use through a traditional oral communication approach from the direct training groups to the indirect intervention groups and broad peer networks within the Yi, Tibetan and Han cultural communities. Key findings showed that the peer-based oral communication strategy was effective for encouraging condom use with casual sexual partners in both the direct training group and the indirect peer diffusion group in all three cultural groups. There was no significant change in any of the comparison groups. Although change in the majority Han cultural group was generally greater than in the ethnic minority groups, the results clearly suggest that the methods can be successfully adopted to promote safe sexual behaviour in different cultural groups of China.

    Background High delivery maternal plasma HIV-1 RNA level (viral load, VL) is a risk factor for mother to child transmission and poor maternal health. Objective To identify factors associated with detectable VL at delivery despite initiation of highly active antiretroviral therapy (HAART) during pregnancy. Design Multicenter observational study. Setting 67 US AIDS clinical research sites. Patients HIV-1-positive pregnant women who initiated HAART during pregnancy. Measurements Descriptive summaries and associations between socio-demographic, HIV disease, treatment and pregnancy-related risk factors and detectable VL (>400copies/mL) at delivery. Results Between October 2002 and December 2011, 671 women met inclusion criteria and 13% had detectable VL at delivery. Factors associated with detectable VL included multiparity (16.4% vs 8% nulliparous, p=0.002), black non-Hispanic ethnicity (17.6% vs 6.6% Hispanic and 6.6% white/non-Hispanic, p<0.001), 11th grade or less education (17.6% vs.12.1% high school graduate and 6.7% some college or higher, p=0.013), and initiation of HAART in third trimester (23.9% vs 12.3% second and 8.6% first, p=0.002), timing of HIV diagnosis prior to current pregnancy (16.1% vs 11% during current pregnancy, p=0.051), and timing of first prenatal visit in 3rd trimester (33.3% vs 14.3% second and 10.5% first, p=0.002). Women who experienced treatment interruptions or reported poor medication adherence during pregnancy were more likely to have detectable VL at delivery than women with no interruptions or who reported better adherence. Limitations Women entered the study at varying times during pregnancy and for this and other reasons there was incomplete data on many covariates. Conclusions In this large U.S.-based cohort of HIV-1 positive women, 13% of women who initiated HAART during pregnancy had detectable VL at delivery. The timing of HAART initiation and prenatal care along with medication adherence during pregnancy appear to be

    A previously unknown Spanish-language mutual aid resource for substance use and mental health concerns is available in Latino communities across the USA and much of Latin America. This kind of ‘4th and 5th step’ group is a ‘culturally adapted’ version of the 12-step programme and provides empirical grounds on which to re-theorise the importance of spirituality and culture in mutual aid recovery groups. This article presents ethnographic data on this organisation. PMID:26755953

    In a group of homosexual men in Vancouver studied prospectively since November 1982, 26 cases of acquired immune deficiency syndrome (AIDS) have arisen. To identify behavioural, clinical and laboratory findings that might predict the development of AIDS in people with antibody to human immunodeficiency virus (HIV), we compared data for 25 patients with AIDS with corresponding data for 80 controls serologically positive for HIV selected from the cohort. The clinical and laboratory data for the patients with AIDS preceded the diagnosis of the syndrome by a mean of 17.5 months. The controls had been both seropositive and AIDS-free for a mean of 16.7 months after acquisition of their data. We detected significant differences between the patients with AIDS and the controls in IgG and IgA levels, absolute number of helper T cells and ratio of helper to suppressor T cells but not in lifetime number of male sexual partners, frequency of receptive anal intercourse or receptive fisting, illicit drug use or history of infectious disease. We also detected an increased risk of AIDS among those who had an elevated number of sexual contacts in AIDS-endemic areas in the 5 years before enrollment. A history of increased early sexual contact in AIDS-endemic areas is likely to be associated with early infection and with an increased risk of AIDS among men with HIV infection of unknown duration. Thus, although our analysis had limited statistical power, we conclude that most lifestyle variables appear to act as exposure factors in HIV infection but not as cofactors in the development of AIDS.

    An expanding body of literature explores the role of African church groups in facilitating or hindering the support of people living with AIDS and challenging or contributing to HIV/AIDS-related stigma. Treating church groups as social spaces in which HIV/AIDS-related stigma may potentially be challenged, we systematically review this literature, identifying five themes that highlight the complex and contradictory role of the church as a potential agent of health-enhancing social change. In many ways the church perpetuates HIV/AIDS-related stigma through (i) moralistic attitudes and (ii) its reinforcement of conservative gender ideologies. However some churches have managed move towards action that makes a more positive contribution to HIV/AIDS management through (iii) promoting various forms of social control for HIV prevention, (iv) contributing to the care and support of the AIDS-affected and (v) providing social spaces for challenging stigmatising ideas and practices. We conclude that church groups, including church leadership, can play a key role in facilitating or hindering the creation of supportive social spaces to challenge stigma. Much work remains to be done in developing deeper understandings of the multi-layered factors that enable some churches, but not others, to respond effectively to HIV/AIDS. PMID:20668927

    2002-08-01

    Recent work has been conducted to develop group tracking algorithms that identify and track multiple targets. One of the characteristics of the group tracking algorithms is the ability to correctly identify the target. If enough evidence has been accumulated to identify the target, the algorithms perform well. However, in the case of spurious measurements and obscured targets, the target identity may not be completely realizable. For the case in which the target identity is not discerned, it is important to classify the target based on some methodology to aid the user. Such a classification could be an allegiance so that when the algorithm groups targets, the information is useful to the human. One sensor that is ideal for the scenario is an Identify Friend Foe Neutral (IFFN) sensor which can classify the target allegiance. By incorporating an IFFN sensor in the GRoup IMM-JBPDAF Tracker (GRIT) algorithm, results show that when identity information is not available, target classification is realizable with allegiance features. Results are simulated for a high-range resolution radar (HRR) and an IFFN sensor and a 29% reduction in the computational classification due to the presence of clutter.

    The identification of Acquired Immunodeficiency Syndrome (AIDS) in 1981, and the subsequent isolation of the human immunodeficiency virus (HIV) in 1983, signaled the beginning of worldwide concern over the potential impact of the disease. As the global incidence of AIDS and HIV infection increased, Canadians expressed growing apprehension about the epidemic's affect on themselves. Because adolescents potentially are at risk for HIV infection, a special need existed to determine how Canadian youth were responding to the AIDS epidemic. During the summer of 1987, the Federal Centre for AIDS, in conjunction with the National Health Research and Development Program and the Canadian Public Health Association, commissioned a nationwide study. A national sample of more than 38,000 youth in grades 7, 9, 11, and the first year of college and university were surveyed about their knowledge, attitudes, and behavior concerning AIDS and other sexually transmitted diseases (STDs). Also included in the total sample were youth who had recently dropped out of school and those who lived on the streets of large cities. In this article, the authors summarize findings from the study and offer conclusions and recommendations for action. PMID:2716287

    Background Despite the rapid rise in the use of multicompartmental compliance aids (MCAs), little is known about the role they play in self-management of medication. Aim To explore the perceived benefits of MCAs for people using them to manage their own or a relative's medication. Design of study Qualitative study using in-depth interviews. Setting West Northumberland. Method Recruitment was via posters and leaflets in general practices and community pharmacies. In-depth interviews were conducted using a topic guide. Results Nineteen people were interviewed. Three overarching themes emerged in relation to medicine taking: disruption, organisation, and adherence, which impacted on control. The medication regime had caused disruption to their lives and this had led to the purchase of an MCA. The MCA enabled them to organise their medication, which they believed had improved the efficiency of medicine taking and saved time. Although the MCA did not prompt them to take their medication, they could see whether they had actually taken it or not, which alleviated their anxiety. To meet their individual needs and lifestyles, some had developed broader systems of medication management, incorporating the MCA. For a small cost – the initial outlay for the MCA and time spent loading it – they gained control over the management of their medication and their condition. Conclusion This group found the use of an MCA to be beneficial, but advice and support regarding how best to manage their medication and on the most appropriate design to suit their needs would be helpful.

    The NCR receptors play a fundamental role in the cytotoxicity mediated by NK cells against tumor cells. In the current study, we investigated possible HIV/AIDS-related changes in the expression of the NCR receptors comparing healthy donors, HIV/AIDS patients, and HIV/AIDS patients with cancer (HIV/AIDSWC). The NCRs were quantified in NK cells (NKdim and NKbright) and T lymphocytes from peripheral blood samples by flow cytometry. We found a significant decrease in the frequency of NK cells expressing NKp46 in HIV/AIDS group (p = 0.0012). There was a decrease in the frequency of NK cells expressing NKp46 in the HIV/AIDSWC group; however, this was not statistically significant. We found a significant decrease in the frequency of NK cells expressing NKp30 in the HIV/AIDS group (p = 0.0144). There was a decrease in the frequency of NK cells expressing NKp30 and in the HIV/AIDSWC group, but this was not statistically significant. There were no changes in the distribution of NK cells and their subtypes in both groups. PMID:27382604

  7. Political will, traditional leaders and the fight against HIV/AIDS: a South African case study.

    PubMed

    Campbell, Catherine

    2010-01-01

    "Political will" and leadership are increasingly considered key contextual influences on the outcomes of HIV/AIDS programmes in sub-Saharan Africa. Such debates tend to focus on the role of national leadership in shaping responses to the epidemic, with little attention to local leaders. Yet many of the settings in which HIV/AIDS flourishes are geographically distant from the reach of national leadership and policies. Furthermore, local leaders often play a key role in shaping how national policies and decisions are interpreted and implemented in local areas. Against this background, we present a case study of the impact of the leadership style of a traditional Chief on a community-based AIDS programme in a South African rural community, which sought to build community-level "AIDS competence", using the "empowerment via participation" approach. The case study involved 134 interviews and 57 focus groups conducted over three years. Thematic content analysis revealed a number of direct and indirect ways in which his leadership style impacted on project outcomes. Despite his strong support for the programme, the Chief's "traditional" attitudes towards women and youth, his celebration of polygamy, and his authoritarian governance style undermined the project's "empowerment via participation" agenda - especially the programme's attempts to reduce AIDS stigma, to build female and youth capacity to control their sexual health, and to encourage men to take responsibility for their role in tackling AIDS.

A subset of subjects underwent fat biopsies at baseline and week 96 for mtDNA content (real-time polymerase chain reaction) and oxidative phosphorylation nicotinamide adenine dinucleotide (reduced) dehydrogenase (complex I) and cytochrome c oxidase (complex IV) activity levels (immunoassays). Intent-to-treat analyses were performed using analysis of variance and paired t tests. Results. Fifty-six subjects (87% male; median age, 39 years) were included; their median body mass index, CD4 cell count, and fat mtDNA level were 26 kg/m2, 227 cells/μL, and 1197 copies/cell, respectively. Fat mtDNA content decreased within the ABC/3TC and TDF/FTC groups (combining EFV and ATV/r arms; median change, −341 [interquartile range, −848 to 190; P = .03] and −400 [−661 to −221; P < .001] copies/cell, respectively), but these changes did not differ significantly between the 2 groups (P = .57). Complex I and IV activity decreased significantly in the TDF/FTC group (median change, −12.45 [interquartile range, −24.70 to 2.90; P = .003] and −8.25 [−13.90 to −1.30; P < .001], optical density × 103/µg, respectively) but not the ABC/3TC group. Differences between the ABC/3TC and TDF/FTC groups were significant for complex I (P = .03). Conclusions. ABC/3TC and TDF/FTC significantly and similarly decreased fat mtDNA content, but only TDF/FTC decreased complex I and complex IV activity levels. Clinical Trials Registration. NCT00118898. PMID

    HIV/AIDS is a serious public health problem in Swaziland, a small land-locked Southern African country. The epidemic affects all subpopulations, but women are increasingly at risk for contracting the disease. Focus groups were conducted in a rural area to obtain qualitative information on the rural dimensions of HIV/AIDS, vulnerability to HIV/AIDS, and sociocultural factors influencing the spread of AIDS. Five themes were identified from analyses of the focus groups that are relevant in developing an AIDS prevention program for this population in Swaziland. Implications for future research and health care practice focus on gender-sensitive cultural research (e.g., women and men's roles and responsibilities in rural Swaziland society) and how social, economic, and cultural factors impact the spread of AIDS. Recommendations include reorienting and allocating resources for health, education, and social services to address the relative neglect of rural areas and strengthening policies and programs to achieve the equal participation of all women in all aspects of society's decisions. Specifically, policies related to economic and food security should result in programs to improve local access by women to all resources. PMID:11868964

    The HIV/AIDS epidemic caused by commercial blood donation in rural Henan Province of China in the early- to mid-1990s is the largest known cohort in the world related to blood donation but is not fully described. The objectives of this study were to describe the epidemic, epidemiology, and social epidemiology of commercial blood donation and HIV/AIDS. Both qualitative and quantitative mixed methods were used. A village was randomly selected from the 38 key HIV/AIDS pandemic villages in Henan Province. "Demographic Data Form" was applied to collect demographic information of each resident. Focus groups were held for the managers, some residents, members of "HIV/AIDS Work-Team" (organized by the Henan Provincial Government) in the village. Every village physician, people living with HIV/AIDS (PLWHA), school header, and other stakeholders were interviewed individually. The social epidemiology of HIV/AIDS was analyzed under three perspectives of the framework: individual, social, and structural perspectives. In this village, there were 2335 residents, 484 (20.3%) were former donors, 107 (4.6%) were PLWHA, and 96.3% of PLWHA were infected through commercial blood donation. Individually, low education and plasma donation were the risky factors of HIV/AIDS infection. Socially, the epidemic was geography-, kinship-, and conformity-related. Structurally, the related macrostructure factor was policy endorsement of national blood products. The microstructure factors were poverty and value belief on male child in passing down generations. It is concluded that commercial blood donation and HIV/AIDS epidemic in the village are symbiotically related. The epidemic is temporary and socially determined. PMID:22835156

    Aims To examine how a rural community profoundly affected by escalating rates of largely AIDS-related deaths of young and middle-aged people makes sense of this phenomenon and its impact on their everyday lives. Methods Data were collected in Agincourt subdistrict, Limpopo Province. Twelve focus groups were constituted according to age and gender and met three times (a total of 36 focus-group discussions [FGDs]). The FGDs explored sequentially people’s expectations of their lives in the “new” South Africa, their interpretations of the acceleration of death amongst the young and middle-aged, and their understandings of HIV/AIDS. Discussions were recorded, fully transcribed, and thematically analysed. Results Respondents acknowledged escalating death rates in their community, yet few referred directly to HIV/AIDS as the cause. Rather, respondents focused on the social and cultural causes of death, including the erosion of cultural norms and traditions such as cultural taboos on sex. There are many competing versions of what HIV/AIDS is, what causes it and how it is spread, ranging from scientific explanations to conspiracy theories. Findings highlight the relationship between AIDS and other traditional diseases with some respondents suggesting that AIDS is a new form of other longstanding illnesses. Conclusions This study points to the centrality of cultural explanations in understanding “bad death” (AIDS death) in the Agincourt area. Physical illness is understood to be a symptom of “cultural damage”. Implications of this for public health practice and research are outlined. PMID:17676515

    The paper compares rural perspectives in Thailand and Ghana on the level of condom acceptance in sexual relations, willingness to test oneself for HIV before and in marriage and sources of information on HIV/AIDS. We also compared the policy approaches to combating HIV/AIDS in both countries. The results indicates that in the villages studied in Thailand, all single men and the majority of the single women were in favour of using condoms in sexual relations. This group also showed a positive attitude to HIV/AIDS test before and in marriage. However, married men in rural Thailand disapproved of the use of condoms with their wives but married women in the sample population were open to the possibility of using condoms. Both married men and women were strongly against HIV/AIDS test in marriage. In contrast to Thailand, most single men in the communities studied in Ghana showed a disapproval to the use of condoms in sexual relations. However, they condoned HIV test before marriage. Married men and women in rural Ghana were against the use of condoms in sexual relations as well as HIV/AIDS test in marriage. In order to mitigate mother-to-child transmission, the Thais applied anti-retroviral drug care for HIV positive pregnant women during pregnancy and after delivery. In Ghana on the other hand, pregnant women were subject to HIV test and counselling. The mode of information acquisition on HIV/AIDS in both countries were through the media, campaigns and village volunteers. Finally, we observed that fighting poverty is a sine qua non for the success of any HIV/AIDS eradication programme. PMID:15760696

    As a result of the collapse of the national economy and political instability, Zimbabwe has experienced a diaspora in recent years. Although Zimbabweans are now the largest immigrant group in most sub-Saharan countries, Zimbabwean immigrants are a mostly illegal and socioeconomically marginalized population. This study explores the lives of Zimbabwean workers in Botswana from a health communication perspective and provides suggestions for accelerating the diffusion of HIV/AIDS prevention information and practices among the target population. In particular, this ethnographic report portrays how the Zimbabwean workers in Botswana make sense of their surroundings and perceive information on HIV/AIDS prevention and other public health risks. Field data analysis highlights several communication features among the immigrants, including reliance on interpersonal communication, high rate of mobile phone adoption, inaccurate public awareness on HIV/AIDS and prevention messages, and stagnated communication with health care services. By connecting Dervin's sensemaking theory to Roger's diffusion of innovations theory, the suggestions from this study can be applied to design HIV/AIDS prevention interventions for the immigrants and socioeconomically marginalized groups.

    This qualitative study explored parents' and young adolescents' perceptions of communication related to sex and HIV/AIDS. Focus group discussions and group discussion were conducted among 67 adolescents and 30 parents. For the adolescents, group discussion using participatory activities was conducted, followed by five focus group discussions. Group discussions using participatory activities were conducted among parents. Thematic analysis indicated that the adolescents received inadequate information about sex and AIDS from their parents, whom they feared as providing negative judgment, and this represented a key barrier to such discussions. Their parents, on the other hand, reported that they believed their children were still too young to learn about and engage in sexual activities. The parents perceived barriers to communication included a lack of confidence and feelings of embarrassment. Nevertheless, they also recognized their important role in their child's sexual education. Collectively, these results draw attention to the need for a culturally appropriate program to strengthen parent-child communication skills for the topics of sex and HIV/AIDS. PMID:23692292

    During the past 10 years, the Southeastern Cancer Study Group (SECSG) has been engaged in one major adjuvant study and three major advanced disease studies for patients with adenocarcinoma of the breast. The adjuvant study is demonstrating that six months of adjuvant CMF is the therapeutic equivalent of 12 months and that post-operative irradiation is of no added therapeutic benefit. In patients with advanced disease, a low dose 5 drug combination of CMFVP induces more objective responses than single agent 5FU, but improves survival only for those patients with liver metastases when compared to the sequential use of the same 5 single agents. The three drug combination, CAF, utilizing doxorubicin, induces more objective responses than low dose CMFVP, but it does not improve overall survival. The addition of a phase active combination, CAMELEON, (i.e., sequentially alternating therapy) of CAF has not improved the duration of disease control and survival for patients with liver metastases, lymphangitic and nodular lung metastases compared to CAF. Aggressive combination chemotherapeutic approaches to patients with advanced disease provide better and longer disease and tumor control but only marginal improvements in overall survival. Adding additional agents to a maximally tolerable regimen has not improved the therapeutic outcome.

    1997-12-01

    Western health officials believe the incidence of HIV infection in the People's Republic of China is much higher than has been reported, but knowledge about the disease remains low. This paper describes a preliminary study of Chinese college students' AIDS knowledge and beliefs and of the acceptability of mass media for AIDS education. Focus group interviews of 73 Xiamen University students showed that the students used radio more consistently than any other media and viewed magazines as the best media source of health information. However, they expressed a general distrust of the health information media offer. They possessed quite a bit of accurate information about AIDS but also harbored many inaccurate beliefs. Most felt that their personal risk from AIDS was very low because they felt distanced--either geographically or morally--from those at risk. Disturbing numbers felt that fate, not individual behavior, determines whether or not a person contracts HIV. The paper discusses the study's implications for future research. PMID:9451483

    Traditionally viruses are studied with scanning electron microscopy (SEM) after complicated procedure of sample preparation without the possibility to study it under natural conditions. We obtained images of viruses (Vaccinia virus, Rotavirus) and rickettsias (Rickettsia provazekii, Coxiella burnetti) in native state with computer-aided phase microscope airyscan -- the interference microscope of Linnik layout with phase modulation of the reference wave with dissector image tube as coordinate-sensitive photodetector and computer processing of phase image. A light source was the He-Ne laser. The main result is coincidence of dimensions and shape of phase images with available information concerning their morphology obtained with SEM and other methods. The fine structure of surface and nuclei is observed. This method may be applied for virus recognition and express identification, investigation of virus structure and the analysis of cell-virus interaction.

    This study aimed to explore the survival of AIDS patients treated with traditional Chinese medicine (TCM) in addition to combined antiretroviral therapy (cART) and of AIDS patients treated with cART. Data of patients taking cART between 30 October 2003 and 30 October 2004 in the National TCM HIV Treatment Trial Program area were retrospectively analyzed, with follow-up from 30 October 2004 to 30 October 2012. The log-rank test was used to compare survival between the two groups. A Cox proportional hazards model was used to determine hazard ratios to identify prognostic factors. The study included 521 patients in the TCM + cART group followed up for 3548 person-years and 375 patients in the cART group followed up for 2523 person-years. Mortality rates were 3.2/100 person-years and 4.2/100 person-years in the TCM + cART and cART groups, respectively. The difference in survival was significant. After adjusting for explanatory variables, the mortality rate of AIDS patients in the cART group was 1.7 times higher than in the TCM + cART group. Male sex, older age, little education, and lower CD4 cell count were risk factors for mortality. TCM intervention in addition to cART could increase survival of AIDS patients. PMID:25821482

    Following an overview of theoretical issues in speech-perception training and of previous efforts to enhance hearing aid use through training, a multisite study, designed to evaluate the efficacy of two types of computerized speech-perception training for adults who use hearing aids, is described. One training method focuses on the identification of 109 syllable constituents (45 onsets, 28 nuclei, and 36 codas) in quiet and in noise, and on the perception of words in sentences presented in various levels of noise. In a second type of training, participants listen to 6- to 7-minute narratives in noise and are asked several questions about each narrative. Two groups of listeners are trained, each using one of these types of training, performed in a laboratory setting. The training for both groups is preceded and followed by a series of speech-perception tests. Subjects listen in a sound field while wearing their hearing aids at their usual settings. The training continues over 15 to 20 visits, with subjects completing at least 30 hours of focused training with one of the two methods. The two types of training are described in detail, together with a summary of other perceptual and cognitive measures obtained from all participants. PMID:27587914

    With increasing numbers of people with HIV/AIDS receiving oral dental care, dentists should have sufficient knowledge of the disease, and their attitude should meet professional expectations. HIV and AIDS-related knowledge among dental students provides a crucial foundation for efforts aimed at developing appropriate education on these topics. Accordingly, the aim of this study was to assess the HIV/AIDS-related knowledge and attitudes amongst the 460 dental students of the Institute of Dental Sciences, Bareilly (UP), India. A self-administered survey consisting of fifty-three structured questions was conducted with the students. Overall, the response rate was 79.7 percent. The total mean knowledge and attitudes scores were 78.8 percent (excellent) and 77.7 percent (positive). There was no statistically significant difference between the knowledge and attitude scores of males and females. Regarding oral manifestations, Kaposi's sarcoma and candidiasis were the most identified. The results indicated that the students' knowledge on HIV/AIDS generally increased as they progressed through the curriculum, but their utilization of all barrier techniques for infection control and clinical protocol lacked consistency and compliance. Hence, there is a need to address, more clearly, the students' misconceptions and attitudes towards the disease. PMID:24002860

    In a randomized trial, AIDS Clinical Trials Group (ACTG) protocol 5146 (A5146) investigated the use of TDM to adjust doses of HIV-1 protease inhibitors (PIs) in patients with prior virologic failure on PI-based therapy who were starting a new PI-based regimen. The overall percentage of “PI trough repeats”, such as rescheduled visits or redrawn PI trough specimens, increased from 2% to 5% to 10% as the process progressed from the clinical sites, the PSL, and the study team, respectively. Cumulatively, this represents a 17% rate of failure to obtain adequate PI trough sample. While targeting a turn-around of ≤ 7 days from sample receipt to a drug concentration report, 12% of the received specimens required a longer period to report concentrations. The implementation of dosing changes in the TDM arm were achieved within ≤7 days for 56% of the dose change events, and within ≤14 days for 77% of dose change events. This quality assurance analysis provides a valuable summary of the specific points in the TDM process that could be improved during a multicenter clinical trial including: [1] shortening the timeline of sample shipment from clinical site to the lab, [2] performing the collection of PI trough specimen within the targeted sampling window by careful monitoring of the last dose times and collection times by the clinicians [3] increasing patient adherence counseling to reduce the number of samples that are redrawn due to suspecting inconsistent adherence, and [4] decreasing the time to successful TDM-based dose adjustment. The application of some of these findings may also be relevant to single center studies or clinical TDM programs within a hospital. PMID:20592644

    2007-01-01

    This study compared evidence from two low caste labouring communities in India: a relatively modernized urban group and a rural group in a backward region. It explored their levels of ill health, their capacities to respond to adult illness and the support they received. In each region, a baseline survey of approximately 1,000 households provided background quantitative evidence with qualitative evidence was collected from about 55 families. HIV infection and AIDS deaths were found to occur in the 'less poor' segments of the study group in both regions. In keeping with the official data, they formed a small proportion of the overall mortality and morbidity in this group. Stigma and discrimination were found to be low but fear of stigma was high, generated by the medical response to AIDS and used opportunistically for personal gains. The study provides insights into the structural determinants of health and coping mechanisms in these communities. The best conditions for a healthy life were found in the group that had a rooted community setting, collective political power, migrant economic support and improved working conditions--the less poor rural group. While improved economic status was associated with better health status, this relationship was stronger when combined with the presence of improved working conditions, with social cohesion at family and community levels and with political power as indicated by levels of organized collective representation and identity formation in workplace, local- and state-level politics. However, the traditional forms of social cohesion are under stress and new forms, moderated by commercial relations, are proving inadequate to meet major household shocks, like adult mortality.

    2006-03-01

    We examined beliefs about the origin of HIV as a genocidal conspiracy in men and women of four racial/ethnic groups in a street intercept sample in Houston, Texas. Groups sampled were African American, Latino, non-Hispanic white, and Asian. Highest levels of conspiracy theories were found in women, and in African American and Latino populations (over a quarter of African Americans and over a fifth of Latinos) with slightly lower rates in whites (a fifth) and Asians (less than one in ten). Reductions in condom use associated with such beliefs were however only apparent in African American men. Conspiracy beliefs were an independent predictor of reported condom use along with race/ethnicity, gender, education, and age group. Data suggest that genocidal conspiracy beliefs are relatively widespread in several racial/ethnic groups and that an understanding of the sources of these beliefs is important to determine their possible impact on HIV prevention and treatment behaviors.

    Background: Effective first aid and transportation influences injury-induced mortality. But few qualitative studies have been conducted so far in this area. Objectives: The aim of this study was to identify the content of the first aid and patient transportation course based on experience gained from the Iran-Iraq war. Patients and Methods: This was a conventional qualitative content analysis study; a purposeful sample of 14 first aid and transportation experts who had worked during the Iran-Iraq war was recruited. We collected and analyzed the study data by using the semi-structured interview method and the conventional content analysis approach respectively. Each interview transcript was reviewed several times. Words, sentences, and paragraphs were labeled with codes. Codes were compared with each other and categorized according to their similarities. Similar sub-categories and categories were also grouped together and formed themes. Results: Study participants’ experiences of wartime first aid and transportation (FAT) education fell into two main themes including ‘the congruence of education and educational needs’ and ‘managers’ engagement in FAT education. The four main categories of these two themes were use of appropriate educational facilities, adopting effective teaching strategies, universal FAT education and specialized training skills. Conclusions: The two key requirements of the first aid and transportation courses are practicality and managerial engagement. We developed and provided specific guidance of FAT curriculum by using the study findings. This curriculum is recommended for educating FAT staffs, paramedics, emergency technicians, and military nurses. PMID:25825700

  8. HIV/AIDS through the lens of Christianity: perspectives from a South African urban support group.

    PubMed

    Hlongwana, K; Mkhize, S

    2007-05-01

    HIV is one of the most obscure viruses that humankind has had to face in recent times. Compounding this obscurity are often contesting perspectives on what it means to be HIV infected, and these perspectives are largely constituted by people's rationalisation of complex situations or experiences. Using qualitative research methods and ethnography in particular, this paper reflects on a broad understanding of what it means to live with HIV in the context of Christianity, using research participants' perspectives in an urban support group setting. Two fundamental patterns are evident in this paper: (1) as support group members rationalise their HIV infection, they continuously construct and reconstruct their identities; and (2) support group members rationalise their HIV infection to enhance their coping abilities, using Christianity and the Bible in particular, as a reference. Whilst rationalising HIV infection, three viewpoints emerge. The first viewpoint perceives HIV infection as an affliction by Satan; the second viewpoint sees it as originating from God; while the last viewpoint interprets HIV infection as a negotiated settlement between God and Satan. The paper is intended to trigger debate, and hopefully also to seek and provide answers from various sectors of society, and religious communities in particular, in order to help other HIV positive people in similar situations better manage their HIV condition.

    Summary Background Cardiac complications contribute significantly to morbidity and mortality in children with HIV/AIDS. These rates have been under-reported in sub-Saharan African children. Methods This was an observational, cross-sectional Doppler echocardiographic study of ventricular systolic function, performed at a tertiary clinic on children with HIV/AIDS. Results Left ventricular systolic dysfunction was present in 27.0% of the children with HIV infection and 81.2% of those with AIDS. The mean fractional shortening in the AIDS group (31.6 ± 9.5%) was significantly lower than in the HIV-infected group (35.3 ± 10.5%, p = 0.001). A significant correlation was found with CD4+ cell count and age, and these were the best predictors of left ventricular systolic dysfunction in the stepwise multiple regression analysis (r = 0.396, p = 0.038; r = –0.212, p = 0.025, respectively). Conclusion Left ventricular systolic dysfunction is common in Nigerian children with HIV/AIDS. PMID:26956496

    Background Despite the widespread adoption of automated perimetry, there is still a role for peripheral perimetry. So far there was no accurate quantitative analysis on the change of visual field, most analysis were qualitative and depend on doctor's experience. Method Computer aided diagnose system was designed to judge the accurate change in visual field. Tabu Seach technology was used to identify visual field from the result of Peripheral perimeter test, and accurate visual filed defect dimension can be concluded by compared with point to point. At the same time liable eye diseases were predicted by computer. Conclusion Computer aided peripheral visual field diagnose system can identify defect in visual field, and provide reliable clinical diagnosis. Key words peripheral visual field, Computer aided diagnose, tabu search. PMID:17282924

    1979-01-01

    The satellite system requires the use of a large satellite antenna and spacecraft array power of about 12 kW or more depending on the operating frequency. Technology developments needed include large offset reflector multibeam antennas, satellite electrical power sybsystems providing greater than 12 kW of power, signal switching hardware, and linearized efficient solid state amplifiers for the satellite-aided mobile band. Presently there is no frequency assignment for this service, and it is recommended that an allocation be pursued. The satellite system appears to be within reasonable extrapolation of the state of the art. It is further recommended that the satellite-aided system spacecraft definition studies and supporting technology development be initiated.

    1995-10-01

    A tank grouping study has been conducted to find Hanford single-shell tanks with similar waste properties. The limited sampling resources of the characterization program could be allocated more effectively by having a better understanding of the groups of tanks that have similar waste types. If meaningful groups of tanks can be identified, tank sampling requirements may be reduced, and the uncertainty of the characterization estimates may be narrowed. This tank grouping study considers the analytical sampling information and the historical information that is available for all single-shell tanks. The two primary sources of historical characterization estimates and information come from the Historical Tank Content Estimate (HTCE) Model and the Sort on Radioactive Waste Tanks (SORWT) Model. The sampling and historical information are used together to come up with meaningful groups of similar tanks. Based on the results of analyses presented in this report, credible tank grouping looks very promising. Some groups defined using historical information (HTCE and SORWT) correspond well with those based on analytical data alone.

    Background Initiation of combination antiretroviral therapy (ART) results in higher total CD4 cell counts, a surrogate for immune reconstitution. Whether the baseline CD4 cell count affects reconstitution of immune cell subsets has not been well characterized. Methods Using data from 978 patients (621 with comprehensive immunological assessments) from the AIDS [Acquired Immunodeficiency Syndrome] Clinical Trials Group protocol 384, a randomized trial of initial ART, we compared reconstitution of CD4+, CD4+ naive and memory, CD4+ activation, CD8+, CD8+ activation, B, and natural killer cells among patients in different baseline CD4+ strata. Reference ranges for T cell populations in control patients negative for human immunodeficiency virus (HIV) infection were calculated using data from AIDS Clinical Trials Group protocol A5113. Results Patients in the lower baseline CD4+ strata did not achieve total CD4+ cell counts similar to those of patients in the higher strata during 144 weeks of ART, although CD4+ cell count increases were similar. Ratios of CD4+ naive-memory cell counts and CD4+:CD8+ cell counts remained significantly reduced in patients with lower baseline CD4+ cell counts (≤350 cells/mm3). These immune imbalances were most notable for those initiating ART with a baseline CD4+ cell count ≤200 cells/mm3, even after adjustment for baseline plasma HIV RNA levels. Conclusions After nearly 3 years of ART, T cell subsets in patients with baseline CD4+ cell counts >350 cells/mm3 achieved or approached the reference range those of control individuals without HIV infection. In contrast, patients who began ART with ≤350 CD4+ cells/mm3 generally did not regain normal CD4+ naive-memory cell ratios. These results support current guidelines to start ART at a threshold of 350 cells/mm3 and suggest that there may be immunological benefits associated with initiating therapy at even higher CD4+ cell counts.

    1984-01-01

    The NASA study activities in preparation for a Space Station began in the early 1970's. The early studies included many in-house NASA and contracted studies. A group of representatives from all the NASA Centers, titled the Space Station Concept Development Group (CDG) was involved in the studies which led to the initiation of the Space Station Program. The CDG studies were performed over a period of approximately one year and consisted of four phases. The initial phase had the objective to determine the functions required of the station as opposed to a configuration. The activities of the second phase were primarily concerned with a sizing of the facilities required for payloads and the resources necessary to support these mission payloads. The third phase of studies was designed to develop a philosophical approach to a number of areas related to autonomy, maintainability, operations and logistics, and verification. The fourth phase of the study was to be concerned with configuration assessment activities.

    2007-01-01

    Background Single nucleotide polymorphisms (SNPs) and genes that exhibit presence/absence variation have provided informative marker sets for bacterial and viral genotyping. Identification of marker sets optimised for these purposes has been based on maximal generalized discriminatory power as measured by Simpson's Index of Diversity, or on the ability to identify specific variants. Here we describe the Not-N algorithm, which is designed to identify small sets of genetic markers diagnostic for user-specified subsets of known genetic variants. The algorithm does not treat the user-specified subset and the remaining genetic variants equally. Rather Not-N analysis is designed to underpin assays that provide 0% false negatives, which is very important for e.g. diagnostic procedures for clinically significant subgroups within microbial species. Results The Not-N algorithm has been incorporated into the "Minimum SNPs" computer program and used to derive genetic markers diagnostic for multilocus sequence typing-defined clonal complexes, hepatitis C virus (HCV) subtypes, and phylogenetic clades defined by comparative genome hybridization (CGH) data for Campylobacter jejuni, Yersinia enterocolitica and Clostridium difficile. Conclusion Not-N analysis is effective for identifying small sets of genetic markers diagnostic for microbial sub-groups. The best results to date have been obtained with CGH data from several bacterial species, and HCV sequence data. PMID:17672919

    This multi-centre repeated measures study was undertaken to determine how contrasting designs of cognitive aids affect team performance during simulated intra-operative anaphylaxis crises. A total of 24 teams consisting of a consultant anaesthetist, an anaesthetic trainee and anaesthetic assistant managed three simulated intra-operative anaphylaxis emergencies. Each team was assigned at random to a counterbalanced order of: no cognitive aid; a linear cognitive aid; and a branched cognitive aid, and scored for team functioning. Scores were significantly higher with a linear compared with either a branched version of the cognitive aid or no cognitive aid for 'Team Overall Behavioural Performance', difference between study groups (F-value) 5.8, p = 0.01. Aggregate scores were higher with the linear compared with the branched aid design (p = 0.03). Cognitive aids improve co-ordination of the team's activities and support team members to verbalise their actions. A linear design of cognitive aid improves team functioning more than a branched design. PMID:26792648

    Purpose This pilot study examined factors influencing classroom hearing aid use in school-age children with hearing loss. Method The research team visited classrooms of 38 children with mild-to-moderate hearing loss (Grades 1–7) on 2 typical school days, twice per day, to document hearing aid use. In addition, parents reported the number of hours their children used hearing aids at school. Results Nearly 24% of children were observed not wearing their hearing aids in the classroom on either observation day. Both grade level and degree of hearing loss appeared to affect hearing aid use. Children in Grades 5–7 and those with milder hearing losses were less likely to wear hearing aids. Overall, parents accurately reported classroom hearing aid use; however, those with children in Grades 5–7 were less accurate than those with children in earlier grades. Conclusions These preliminary results suggest that children with milder hearing loss and those in Grades 5–7 are at increased risk for reduced hearing aid use in the classroom. Also, parents of school-age children in these later grades are less accurate reporters of classroom hearing aid use compared to parents of children in earlier grades. PMID:26650231

    2012-01-01

    Background The continuous increase in number of people living with HIV/AIDS (PLWHA) represents a serious health and economic burden. HIV positive individuals with oral lesions have significantly lower oral health-related quality of life than HIV positive individuals without oral lesions. The objective of this study was to assess the knowledge, attitude and practices (KAP) within a cohort of HIV/AIDS positive patients towards HIV/AIDS associated oral lesions. Methods Two hundred seventy patients attending a national referral hospital of infectious disease in Malaysia were recruited for the study. The study involved the administration of a validated interview-based questionnaire designed to elicit knowledge, attitude and practices of these patients towards HIV associated oral lesions. The last part of the questionnaire assessed the training provided to the patients in relation to the oral lesions associated with the disease and the effectiveness of this training. Data analysis was carried out using SPSS version 18. Results Thirty seven percent of patients were reported as knowledgeable, while sixty four percent reported to have positive attitude towards the care of oral hygiene. Sixty six percent of the patients reported that they would seek professional care when experiencing oral lesion. Training was reported effective for 93% patients. Conclusions Patients were non-knowledgeable in relation to oral manifestations of the disease and one third of the participating patients showed negative attitudes towards oral health care and reported various measures to manage oral lesions rather than seeking professional care. Developing effective educational methodologies can empower patients with knowledge that may translate to positive attitudes and practices. PMID:23043358

    Background The aim of this study was to investigate and present some pertinent comments concerning Acquired Immunodeficiency Syndrome (AIDS) knowledge, attitudes and misconceptions among the general population in a city of west Turkey. This study was deemed important and relevant due to the increasing importance of AIDS in Turkey and the other countries. Methods Using a multistage area sampling method, a random sample of individuals aged 11–83 years, living in 65 different quarters in the city of Eskisehir, Turkey during September, October and November 2004 were interviewed. Results In all, 1048 respondents completed the survey. In most items, respondents displayed a fairly good to excellent degree of knowledge about HIV/AIDS. Individuals with higher degrees of education indicated more correct responses in all items relating to knowledge of HIV/AIDS. In general, the respondents' attitudes towards AIDS and people with AIDS were found to be tolerant and positive, with one answer choice showing that the majority of the respondents agreed with the statement that those with HIV/AIDS must be supported, treated and helped (90.7%). Moreover, the proportions of the respondents' misconceptions were found to be significantly low for all the items. However, nearly one fourth of the respondents agreed with the misconceptions 'AIDS is a punishment by God' and 'One is not infected with HIV/AIDS if engaged in sport and well nourished'. Conclusion In general HIV/AIDS related knowledge was high and people showed positive attitudes. However, people continue to hold misconceptions about AIDS and these need to be addressed by health education programs targeting those at higher risk. PMID:16159400

    The aim of the study was to develop an HIV and AIDS training manual, and to evaluate the knowledge, attitudes and management of faith healers of Apostolic churches regarding HIV and AIDS, before and after they attended an HIV and AIDS training programme. A quasi-experimental intervention design was used with faith healers affiliated with the United African Apostolic Church (UAAC) in the Thulamela and Musina municipalities of Vhembe District, Limpopo Province, South Africa. A total of 103 faith healers were included in this study, 58 were systematically assigned to an intervention and 45 to a control group. The intervention group received training for 2 days. At follow-up after 2 months, intervention effects were significant for HIV knowledge and to a lesser extent TB knowledge. No significant improvement was found in HIV/STI (sexually transmitted infection) management strategies such as HIV/STI risk behaviour counselling, referral of clients for HIV testing, keeping condoms at stock in church, and church community HIV/AIDS/STI education. It is important to note that faith healers address some of the major known behavioural risk and protective factors such as partner reduction and condom use. Therefore, faith healers could be more widely utilized in HIV prevention programmes as risk reduction counsellors, in particular on matters of community-level education. PMID:22754060

    2004-12-01

    Memory problems are the most common cognitive deficits in dementia. In order to help these patients with their everyday activities and to increase their quality of life, a number of memory aids have been developed. This paper focuses on the efficacy and the applicability of three different types of external memory aids. The findings suggest that environmental adjustment is an easy and low-priced method. It is beneficial even for patients in the most severe stages of dementia, since only a limited amount of training is necessary. The non-electronic aids are also relatively cheap and easy to learn. The electronic aids are more expensive and, at this point, only a few studies have investigated the efficacy of this memory aid on the memory problems of patients with dementia. However, most published studies only investigated small samples. Hence, the current results should be interpreted with caution. PMID:15704603

    SILVA, Jane DA; RAMOS, Victoria; SILVA, Helena Caetano Gonçalves DA; TRAEBERT, Jefferson

    2015-01-01

    Introduction: The purpose of measuring the burden of disease involves aggregating morbidity and mortality components into a single indicator, the disability-adjusted life year (DALY), to measure how much and how people live and suffer the impact of a disease. Objective: To estimate the global burden of disease due to AIDS in a municipality of southern Brazil. Methods: An ecological study was conducted in 2009 to examine the incidence and AIDS-related deaths among the population residing in the city of Tubarao, Santa Catarina State, Brazil. Data from the Mortality Information System in the National Health System was used to calculate the years of life lost (YLL) due to premature mortality. The calculation was based on the difference between a standardized life expectancy and age at death, with a discount rate of 3% per year. Data from the Information System for Notifiable Diseases were used to calculate the years lived with disability (YLD). The DALY was estimated by the sum of YLL and YLD. Indicator rates were estimated per 100,000 inhabitants, distributed by age and gender. Results: A total of 131 records were examined, and a 572.5 DALYs were estimated, which generated a rate of 593.1 DALYs/100,000 inhabitants. The rate among men amounted to 780.7 DALYs/100,000, whereas among women the rate was 417.1 DALYs/100,000. The most affected age groups were 30-44 years for men and 60-69 years for women. Conclusion: The burden of disease due to AIDS in the city of Tubarao was relatively high when considering the global trend. The mortality component accounted for more than 90% of the burden of disease. PMID:26603227

    The Cretaceous Cogollo Group, with over 1500 feet of platform carbonate and shale section, contains important oil accumulations in the west portion of the Maracaibo basin. However, after discovery of the major oil fields, all subsequent exploration and exploitation efforts led to disappointing results. This paper summarizes the study of the Cogollo Group in the Lake Maracaibo West Coast area, where light Cretaceous oil may have an impact on the total reserves. After integrating the Cogollo Group into the regional framework, the study focuses on the District Zulia Occidental, where over 40 deep wells either penetrated or tested the reservoir. Structural and stratigraphic descriptions are enriched by a significant amount of core and petrophysical data that leads to a better understanding of the reservoir layering and pore geometry. Well production performance and reservoir data are incorporated to the study as additional tools to determine the size of the oil accumulations. Finally, the study addresses the possibility of drilling slant or horizontal wells as a way to reduce the number of dry holes or marginal producers.

    This paper describes parents' views of the New York City Public High School's AIDS Education and Condom Availability Program. It presents findings from 12 focus groups with 81 parents of students at six representative high schools. Focus groups were conducted as part of an independent, comprehensive 3-year evaluation of the program, consisting of both qualitative and quantitative components. Participants were mostly supportive of the program, citing intense concern about AIDS among adolescents, fear that teenagers do not adequately perceive themselves as being vulnerable, and personal experiences with infected relatives and friends. Implications of these findings for program development are discussed and recommendations for social policy changes are presented. PMID:9083588

    The requirement to phase out mercuric oxide (mercury) batteries on environmental grounds has led to the widespread introduction of zinc-air technology. The possibility arises that high drain hearing aids may not be adequately catered for by zinc-air cells, leading to poor performance. This study investigated the hearing aid user's ability to perceive differences between zinc-air and mercury cells in normal everyday usage. The data was collected for 100 experienced hearing aid users in field trials. Users report 50 per cent greater life for zinc-air cells in high power aids and 28 per cent in low power aids. The average life of the zinc-air cells range from 15 days in high power to 34 days in low power aids. Users are able to perceive a difference in sound quality in favour of zinc-air cells for low and medium power aids. The hearing aid population is not disadvantaged by phasing out mercury cells.

    2011-01-01

    Background The number of nongovernmental organizations working on AIDS has grown. There is great diversity in the type of activities and population groups that have been targeted. The purposes of this study are: to describe and analyze the objectives and HIV-AIDS preventive activities that are carried out by the AIDS-NGOs that work with AIDS in Catalonia and that receive subsidies from the Department of Health; and to develop a comprehensive proposal for measurable and agreed upon core quality evaluation indicators to monitor and assess those objectives and activities that can have an impact on the fight against inequalities and stigmatization, and incorporate the perspectives of the service providers and users. Methods A mixed method study has been carried out with professionals from the 36 NGOs that work with HIV/AIDS in Catalonia, as well as their users. This study achieved the completeness model using the following phases: 1. A systematic review of AIDS-NGOs annual reports and preparation of a catalogue of activities grouped by objectives, level of prevention and AIDS-NGOs target population; 2. A transversal study through an ad-hoc questionnaire administered to the AIDS-NGOs representatives; 3. A qualitative study with a phenomenological approach through focus groups, individual interviews and observations; 4. Consensus meetings between AIDS-NGOs professionals and the research team using Haddon matrices in order to establish a proposal of evaluation indicators. Results The information was classified according to level of prevention and level of intervention. A total of 248 objectives and 258 prevention activities were identified. 1564 evaluation indicators, addressed to 7 target population groups, were produced. Thirty core activities were selected. The evaluation indicators proposed for these activities were: 76 indicators for 15 primary prevention activities, 43 for 5 secondary prevention activities and 68 for 10 tertiary prevention activities.

    Abstract Objective: Explore the meanings attributed by young individuals about "living as an adolescent with HIV" in a group of patients that acquired the infection at birth and the elements involved with the adherence to antiretroviral treatment. Methods: Qualitative study, involving 20 subjects (aged 13-20 years), followed at services specialized in the treatment of pediatric AIDS in São Paulo, Brazil. Semi-structured interviews were carried out of which script consisted of questions about their personal histories, experiences and difficulties they must face while living with HIV/AIDS. Results: Being "normal" and "different" were central issues voiced by the participants. However, a normal life situation is guaranteed by being responsible with one's health, the condition that the diagnosis be kept secret and concerns about HIV transmission and dissemination to a sexual partner. The answers about treatment show that adherence is a dynamic process and involves moments of greater or lesser interest in relation to care for one's health. The adolescents have plans and projects and although HIV is considered a stressor, positive perspectives for the future prevailed. Conclusions: To live as an adolescent with HIV involves subtle dimensions that need to be recognized and legitimized by professionals who follow the trajectory of these young individuals. It is necessary to allow a space in which the adolescents can reflect and find support regarding issues related to the construction of their sexuality and care of one's own body. PMID:26611887

    Background: HIV/AIDS is one of the diseases which not only makes threats to physical health, but also, due to the negative attitudes of people and the social stigma, affects the emotional and social health of patients. The aim of this study was to identify the psychological, social, and family problems of people living with HIV/AIDS (PLWHA) in Iran. Methods: In this qualitative study, we used purposive sampling to enroll PLWHA, their families, and physicians and consultants in two cities of Kermanshah and Tehran. Each group of PLWHA, their families, physicians, and consultants participated in two focus group discussions (FGDs), and a total of eight FGDs were conducted. Six interviews were held with all key people, individually. Results: Based on the views and opinions of various groups involved in the study, the main problems of PLWHA were: Ostracism, depression, anxiety, a tendency to get revenge and lack of fear to infect others, frustration, social isolation, relationship problems, and fear due to the social stigma. Their psychological problems included: Marriage problems, family conflict, lack of family support, economic hardships inhibiting marriage, and social rejection of patient's families. Their family problems were: Unemployment, the need for housing, basic needs, homelessness, and lack of social support associations. Conclusions: It seems that the identification and focusing on psychological, social, and family problems of affected people not only is an important factor for disease prevention and control, but also enables patients to have a better response to complications caused by HIV/AIDS.

  20. Globalization and its methodological discontents: Contextualizing globalization through the study of HIV/AIDS

    PubMed Central

    2011-01-01

    There remains considerable discontent between globalization scholars about how to conceptualize its meaning and in regards to epistemological and methodological questions concerning how we can come to understand how these processes ultimately operate, intersect and transform our lives. This article argues that to better understand what globalization is and how it affects issues such as global health, we must take a differentiating approach, which focuses on how the multiple processes of globalization are encountered and informed by different social groups and with how these encounters are experienced within particular contexts. The article examines the heuristic properties of qualitative field research as a means to help better understand how the intersections of globalization are manifested within particular locations. To do so, the article focuses on three recent case studies conducted on globalization and HIV/AIDS and explores how these cases can help us to understand the contextual permutations involved within the processes of globalization.

    HIV/AIDS is an important public health issue in China. The number of people living with HIV/AIDS (PLWHA) has been increasing since the introduction of highly active antiretroviral therapy. PLWHA's life quality is becoming an important issue, with lack of research in China. In this study, a group of PLWHA (n = 663) was identified using HIV/AIDS relevant usernames on a Chinese social networking site (Weibo) to study their daily living situations. We found that more than 99.10% of PLWHA were male, among whom 90.80% turned out to be homosexual. They had significantly more fans and followees, but fewer postings compared to the general population. The mean age of the PLWHA was 28.96 (SD = 5.05) years old, and southwest and northwest China had a high prevalence of HIV/AIDS. In addition, PLWHA's postings were coded and we found that more than half of the postings (n = 769, 51.03%) contained strong emotions. Less than one-fifth of the postings were directly related to HIV/AIDS topics (n = 269, 17.85%), while seeking emotional support, such as looking for stable partnership, was ranked as the first priority of support seeking. In summary, we found that the majority of the self-labeled PLWHA were likely to be men who have sex with men. They used Weibo to share their daily life events and seek emotional support. Implications for promoting HIV/AIDS education and prevention through Chinese social networking sites were also discussed. PMID:27494331

    Living with HIV, for many of those infected, has meant adjusting to life with a stigmatised condition and, until recently, the threat of looming death. We explore the adjustment of a group of long-term former clients of The AIDS Support Organisation (TASO) in Uganda who, when tested for HIV during the rollout of antiretroviral therapy in 2004, were found to be HIV negative. In-depth semi-structured interviews with 34 former TASO clients were conducted between 2005 and 2007. Their narratives reveal a great deal about the biographical disruption they have faced, and the biographical work that they have undertaken in both the personal and the social dimensions of their lives in order to manage their new-found HIV-uninfected status. After the negative test result, as they were no longer HIV-infected, they had to leave TASO and that support was sorely missed, as was the friendship of TASO members to whom they often felt reluctant to disclose their new status. The identity 'reversal' or change was often handled privately. Compared with their transition to an HIV-positive identity, they now lacked a social dimension to their identity transformation as they managed their new identity in the face of self- and public doubt.

    In a group of HIV positive young male patients without any significant neuropsychiatric signs, computer-analyzed EEG (CEEG) and Dynamic Brain Mapping evaluations were conducted. These patients, who only had micro-neuropsychiatric symptoms, demonstrated CEEG profiles that more closely resemble those of patients diagnosed as suffering from mild dementia than age-related normals from our CEEG data base. The CEEGs of patients diagnosed as having Acquired Immune Deficiency Syndrome (AIDS), compared to patients with HIV positive, showed greater similarity in CEEG patterns to severely demented patients than to normal control groups. The findings of this pilot study suggest that CEEG may be useful for early determination of the Central Nervous System's (CNS) involvement with the AIDS virus and monitoring the progress of the illness.

Drawing on an extensive literature review of studies conducted in sub-Saharan Africa, we focus on those secular institutions that support all effective methods of reducing HIV/AIDS transmission and those conservative religious institutions that support a limited set of prevention methods. We conclude by identifying topics for dialogue between these viewpoints that should facilitate cooperation by expanding the generally acceptable HIV/AIDS prevention methods, especially the use of condoms.

    A replication study was conducted of the treatment of agoraphobics by exposure in cohesive groups, as described by Hand, Lamantagne and Marks (1974). The continuing improvement during follow-up, with consequent large overall improvement, reported in the original study was not replicated. However, the present study confirmed the usefulness of this procedure as a highly cost-efficient treatment. The assumed equivalence of the Gelder and Marks (1966) phobic rating scale and its modification by Watson and Marks (1971) was examined. Large discrepancies between the scales were obtained for initial assessments and change scores. It is suggested that there is a need for workers in this field to agree on methods of measurement.

    1994-01-01

    Over-the-counter (OTC) sleep aids are used in greater proportions than benzodiazepines for the treatment of sleep problems, yet limited research has focused on these nonprescription drugs. This article reports the results of two studies that examined the use of OTC sleep aids and alcohol for sleep problems by university students. Of those subjects in both studies who reported sleep problems 1 day per month or more, 6.4% of men and 11.4% of women reported using OTC sleep aids, however, a significantly greater percentage of men reported using alcohol to induce sleep (23.4% vs. 10.9%, p < .008). Future studies on OTC sleep aids are recommended to address a broader range of issues such as potential side effects and at-risk populations, tolerance effects, and individual differences in responsiveness and sensitivity to these drugs.

    This study aimed to assess the perceived value of the Cognitive Aids for Role Definition (CARD) protocol for simulated intraoperative cardiac arrests. Sixteen interprofessional operating room teams completed three consecutive simulated intraoperative cardiac arrest scenarios: current standard, no CARD; CARD, no CARD teaching; and CARD, didactic teaching. Each team participated in a focus group interview immediately following the third scenario; data were transcribed verbatim and qualitatively analysed. After 6 months, participants formed eight new teams randomised to two groups (CARD or no CARD) and completed a retention intraoperative cardiac arrest simulation scenario. All simulation sessions were video recorded and expert raters assessed team performance. Qualitative analysis of the 16 focus group interviews revealed 3 thematic dimensions: role definition in crisis management; logistical issues; and the "real life" applicability of CARD. Members of the interprofessional team perceived CARD very positively. Exploratory quantitative analysis found no significant differences in team performance with or without CARD (p > 0.05). In conclusion, qualitative data suggest that the CARD protocol clarifies roles and team coordination during interprofessional crisis management and has the potential to improve the team performance. The concept of a self-organising team with defined roles is promising for patient safety. PMID:27294389

    Background The association of inflammatory biomarkers with clinical events after antiretroviral therapy (ART) initiation is unclear. Methods A5202 randomized 1857 treatment-naive subjects to abacavir/lamivudine or tenofovir-DF/emtricitabine with efavirenz or atazanavir/ritonavir. Substudy A5224s measured inflammatory biomarkers on subjects with available plasma from baseline and weeks 24 or 96. An exploratory analysis of the association of hsCRP, IL-6, sTNF-RI, sTNF-RII, TNF-α, sVCAM-1, and sICAM-1 with times to AIDS and to non-AIDS events used Cox proportional hazards models. Results Analysis included 244 subjects; 85% male, 48% white non-Hispanic, with median age 39 years, HIV-1 RNA 4.6 log10 copies/mL, and CD4 240 cells/μL. Overall, 13 AIDS events (9 opportunistic infections; 3 AIDS-cancers, 1 recurrent bacterial pneumonia) and 18 non-AIDS events (6 diabetes, 4 cancers, 3 cardiovascular, 5 pneumonias) occurred. Higher baseline IL-6, sTNF-RI, sTNF-RII, and sICAM-1 were significantly associated with increased risk of AIDS-defining events. Adjustment for baseline HIV-1 RNA did not change results, while adjusting for baseline CD4 count left only sTNF-RI and sICAM-1 significantly associated with increased risk. Time-updated values of IL-6, sTNFR-I and II, and sICAM-1 were also associated with an increased risk. For non-AIDS events, only higher baseline hsCRP was significantly associated with increased risk, while higher IL-6 was marginally associated with higher risk. Analyses of time-updated biomarker values showed TNF-α to be significantly associated with increased risk, even after adjustment for ART, and CD4 count or HIV-1 RNA. Conclusion Higher levels of several inflammatory biomarkers were independently associated with increased risk of AIDS and non-AIDS events. PMID:24121755

    2013-01-01

    Background Patient preference is one of the main components of clinical decision making, therefore leading to the development of patient decision aids. The goal of this study was to describe physicians’ and patients’ viewpoints on the barriers and limitations of using patient decision aids in Iran, their proposed solutions, and, the benefits of using these tools. Methods This qualitative study was conducted in 2011 in Iran by holding in-depth interviews with 14 physicians and 8 arthritis patient. Interviewees were selected through purposeful and maximum variation sampling. As an example, a patient decision aid on the treatment of knee arthritis was developed upon literature reviews and gathering expert opinion, and was presented at the time of interview. Thematic analysis was conducted to analyze the data by using the OpenCode software. Results The results were summarized into three categories and ten codes. The extracted categories were the perceived benefits of using the tools, as well as the patient-related and physician-related barriers in using decision aids. The following barriers in using patient decision aids were identified in this study: lack of patients and physicians’ trainings in shared decision making, lack of specialist per capita, low treatment tariffs and lack of an exact evaluation system for patient participation in decision making. Conclusions No doubt these barriers demand the health authorities’ special attention. Hence, despite patients and physicians’ inclination toward using patient decision aids, these problems have hindered the practical usage of these tools in Iran - as a developing country.

    The Multicenter AIDS Cohort Study (MACS) is one of the largest and longest running studies of the natural and treated history of HIV disease. The Neuropsychological (NP) substudy was begun in 1988 following reports of significant adverse neurological consequences of HIV disease, including dementia. The goal was to characterize the neuropsychological deficits among individuals with HIV disease, and track the natural history of the neurological complications over time. There were three distinct MACS recruitment stages that focused on different groups of HIV-infected men, or men at risk for infection. Initially, a subcohort was evaluated semi-annually with NP tests but, beginning in 2005, the entire group of MACS participants have had NP examinations biannually, unless closer follow-up was warranted. The participants complete a battery of NP tests, and are classified as either normal, mildly or severely impaired using the Antinori criteria for HIV-Associated Neurocognitive Disorder (HAND). Additional behavioural data, including mood state and psychoactive substance use, are recorded as part of the main MACS data collection. The MACS public data set (PDS) has been available since 1994 and includes baseline and 6-monthly follow-up data. Beginning in October 1995, the PDS has been released annually with new releases superseding previous versions. PMID:24771276

    2014-06-01

    The international study group on data preservation in High Energy Physics, DPHEP, achieved a major milestone in 2012 with the publication of its eagerly anticipated large-scale report [1]. This document contains a description of data preservation activities from all major high energy physics collider-based experiments and laboratories. A central message of the report is that data preservation in HEP is not possible without long term investment in not only hardware but also human resources, and with this in mind DPHEP will evolve to a new collaboration structure in 2013. This paper describes the progress made since the publication of that report - shortly before CHEP 2012 - as well as the future working directions of the new collaboration.

    The results of the economic analysis of the AIDS 3 system design are presented. AIDS 3 evaluated a set of economic feasibility measures including life cycle cost, implementation cost, annual operating expenditures and annual capital expenditures. The economic feasibility of AIDS 3 was determined by comparing the evaluated measures with the same measures, where applicable, evaluated for the current system. A set of future work load scenarios was constructed using JPL's environmental evaluation study of the fingerprint identification system. AIDS 3 and the current system were evaluated for each of the economic feasibility measures for each of the work load scenarios. They were compared for a set of performance measures, including response time and accuracy, and for a set of cost/benefit ratios, including cost per transaction and cost per technical search. Benefit measures related to the economic feasibility of the system are also presented, including the required number of employees and the required employee skill mix.

    2005-01-01

    A study was undertaken in 1997 through 2000 in the rural north of Thailand to describe and theorize the HIV/AIDS experiences of wives and widows there. Participants confronted four causally interrelated problems in their struggle to survive with HIV/ AIDS: physical, economic, psychoemotional, and sociocultural, and they used two social processes to manage them: namely, "hiding out" and "hanging in" with HIV/AIDS. This report describes and discusses the second of these basic social processes through which wives and widows in the rural north of Thailand cope with their HIV/AIDS infection. Hanging in involves a range of very active strategies derived from both traditional Thai culture and Western medicine and aimed at allowing participants to make the best of their predicament. In addition, this report renders explicit what is typically left implicit in grounded theory research; that is, that culture is the source both of the problems participants experienced and the means to their effective amelioration.

    The objective of this study was to compare the results of hearing augmentation with the Retro-X semi-implantable hearing aid to a conventional non-implantable open canal hearing aid using the same software technology (Titan-X, auric Hearing Systems, HiKaNo.:13.20.03.0047). Nineteen subjects (20 ears) with mild to moderate high-frequency sensory-neural hearing loss were included in this clinical study. All the subjects were first fitted with a conventional open canal hearing aid (Titan-X). After a period of 4-6 weeks audiological evaluations were performed using standardized speech tests in quiet and noise. Subjective evaluation was performed with the help of standardized questionnaires. After this phase the patients received the semi-implantable Retro-X device under local anaesthesia and 4 weeks later were fitted with a hearing module with the same software technology as the conventional Titan-X hearing aid. Four weeks following the first fitting the same audiological evaluations were performed under similar conditions and the patients were evaluated again using the same questionnaires in order to compare the results of the Retro-X semi-implantable system with the conventional open canal hearing aid. Audiological evaluations revealed better results with the semi-implantable Retro-X in the adaptive speech in noise test; however, the results of the monosyllabic word test in quiet were similar for the Retro-X and conventional open canal hearing aid. The patients subjectively preferred the improved wearing comfort of the semi-implantable device. The Retro-X semi-implantable hearing aid provides better speech perception in noise and higher wearing comfort in comparison to the conventional open canal hearing aids. Considering the simple implantation procedure under local anaesthesia with low complication rate, Retro-X is an alternative to the conventional open canal hearing aids in patients with mild to moderate high frequency sensory-neural hearing loss.

  3. Fundamental Studies on Donor-acceptor Conjugated Polymers Containing 'Heavy' Group 14 and Group 16 Elements

    NASA Astrophysics Data System (ADS)

    Gibson, Gregory Laird

    One advantage of conjugated polymers as organic materials is that their properties may be readily tuned through covalent modifications. This thesis presents studies on the structure-property relationships resulting from single- and double-atom substitutions on an alternating donor-acceptor conjugated polymer. Specifically, single selenium and tellurium atoms have been incorporated into the acceptor monomer in place of sulfur; silicon and germanium atoms have been substituted in place of carbon at the donor monomer bridge position. The carbon-donor/ tellurium-acceptor polymer was synthesized by a post-polymerization reaction sequence and demonstrated the utility of heavy group 16 atoms to red shift a polymer absorption spectrum. Density functional theory calculations point to a new explanation for this result invoking the lower heavy atom ionization energy and reduced aromaticity of acceptor monomers containing selenium and tellurium compared to sulfur. Absorption and emission experiments demonstrate that both silicon and germanium substitutions in the donor slightly blue shift the polymer absorption spectrum. Polymers containing sulfur in the acceptor are the strongest light absorbers of all polymers studied here. Molecular weight and phenyl end capping studies show that molecular weight appears to affect polymer absorption to the greatest degree in a medium molecular weight regime and that these effects have a significant aggregation component. Solar cell devices containing either the silicon- or germanium-donor/selenium-acceptor polymer display improved red light harvesting or hole mobility relative to their structural analogues. Overall, these results clarify the effects of single atom substitution on donor-acceptor polymers and aid in the future design of polymers containing heavy atoms.

    This exploratory study was conducted to assess the effect of an HIV/AIDS prevention program on producing positive changing attitudes among African-American women in Southeast Georgia. This study used a faith-based approach. Data were collected from 23 respondents recruited from a local African-American church. HIV training was conducted over four 1-hour sessions using web-based interactive videos and lectures on HIV/AIDS. Constructs from the Social Cognitive Theory comprised the framework upon which the women received HIV/AIDS prevention training. Participants completed a 25-item pre- and post-intervention questionnaire to measure any changes that occurred in their attitudes regarding HIV/AIDS. Results showed a statistically significant difference in mean scores of individual knowledge and attitudes about HIV. The difference in mean scores for the remaining items was found to be statistically insignificant. The overall change in attitudes was also statistically significant, t = 2.27, df = 22, p < 0.05, which provided further evidence that when peers educate their communities on HIV/AIDS, it makes a significant difference in changing their attitudes about this disease. Although findings were positive, further data is needed to substantiate and validate the use of community peers to increase knowledge and awareness about HIV/AIDS among the African-American population.

    Hearing aids often develop malfunctions that are not detected by the wearer. This is particularly true when the wearers are school-age children. Studies of selected groups showed that from 30 to more than 50 percent of school children were not getting adequate benefit from their hearing aids because of unrecognized malfunctions, usually low or dead batteries. This can be serious because hearing impairment retards a child's educational progress. NASA technology incorporated in the Hearing Aid Malfunction Detection Unit (HAMDU), the device pictured, is expected to provide an effective countermeasure to the childrens' hearing aid problem. A patent license has been awarded to a minority-owned firm, Hopkins International Company, a subsidiary of H. H. Aerospace Design Co., Inc., Elmford, New York. The company plans early commercial availability of its version of the device.

    Background. Host genetic variation influences human immunodeficiency virus (HIV) infection and progression to AIDS. Here we used clinically well-characterized subjects from 5 pretreatment HIV/AIDS cohorts for a genome-wide association study to identify gene associations with rate of AIDS progression. Methods.  European American HIV seroconverters (n = 755) were interrogated for single-nucleotide polymorphisms (SNPs) (n = 700,022) associated with progression to AIDS 1987 (Cox proportional hazards regression analysis, co-dominant model). Results.  Association with slower progression was observed for SNPs in the gene PARD3B. One of these, rs11884476, reached genome-wide significance (relative hazard = 0.3; P =3. 370 × 10−9) after statistical correction for 700,022 SNPs and contributes 4.52% of the overall variance in AIDS progression in this study. Nine of the top-ranked SNPs define a PARD3B haplotype that also displays significant association with progression to AIDS (hazard ratio, 0.3; P = 3.220 × 10−8). One of these SNPs, rs10185378, is a predicted exonic splicing enhancer; significant alteration in the expression profile of PARD3B splicing transcripts was observed in B cell lines with alternate rs10185378 genotypes. This SNP was typed in European cohorts of rapid progressors and was found to be protective for AIDS 1993 definition (odds ratio, 0.43, P = .025). Conclusions. These observations suggest a potential unsuspected pathway of host genetic influence on the dynamics of AIDS progression. PMID:21502085

    Increasing attention is paid to impacts of HIV/AIDS on women's mental health, often framed by decontextualized psychiatric understandings of emotional distress and treatment. We contribute to the small qualitative literature extending these findings through exploring HIV/AIDS--affected women's own accounts of their distress-focusing on the impacts of social context, and women's efforts to cope outside of medical support services. Nineteen in-depth interviews were conducted with women experiencing depression or anxiety-like symptoms in a wider study of services in KwaZulu-Natal, South Africa. Thematic analysis was framed by Summerfield's emphasis on contexts and resilience. Women highlighted family conflicts (particularly abandonment by men), community-level violence, poverty and HIV/AIDS as drivers of distress. Whilst HIV/AIDS placed significant burdens on women, poverty and relationship difficulties were more central in their accounts. Four coping mechanisms were identified. Women drew on indigenous local resources in their psychological re-framing of negative situations, and their mobilisation of emotional and financial support from inter-personal networks, churches and HIV support groups. Less commonly, they sought expert advice from traditional healers, medical services or social workers, but access to these was limited. Though all tried to supplement government grants with income generation efforts, only a minority regarded these as successful. Findings support ongoing efforts to bolster strained mental health services with support groups, which often offer valuable emotional and practical support. Without parallel poverty alleviation strategies, however, support groups may sometimes offer little more than encouraging passive acceptance of the inevitability of suffering--potentially exacerbating the hopelessness underpinning women's distress.

    The emergence of alternative medicines for AIDS in Asia and Africa was discussed at a satellite symposium and the parallel session on alternative and traditional treatments of the AIDSImpact meeting, held in Marseille, in July 2007. These medicines are heterogeneous, both in their presentation and in their geographic and cultural origin. The sessions focused on the role of these medications in selected resource poor settings in Africa and Asia now that access to anti-retroviral therapy is increasing. The aims of the sessions were to (1) identify the actors involved in the diffusion of these alternative medicines for HIV/AIDS, (2) explore uses and forms, and the way these medicines are given legitimacy, (3) reflect on underlying processes of globalisation and cultural differentiation, and (4) define priority questions for future research in this area. This article presents the insights generated at the meeting, illustrated with some findings from the case studies (Uganda, Senegal, Benin, Burkina Faso, China and Indonesia) that were presented. These case studies reveal the wide range of actors who are involved in the marketing and supply of alternative medicines. Regulatory mechanisms are weak. The efficacy claims of alternative medicines often reinforce a biomedical paradigm for HIV/AIDS, and fit with a healthy living ideology promoted by AIDS care programs and support groups. The AIDSImpact session concluded that more interdisciplinary research is needed on the experience of people living with HIV/AIDS with these alternative medicines, and on the ways in which these products interact (or not) with anti-retroviral therapy at pharmacological as well as psychosocial levels.

    The aim of the study was to develop and evaluate the impact of an educational intervention with the use of text messages (SMS) in a first aid course. A prospective study and intervention was conducted. Two steps were implemented: 1) a qualitative study to design the SMS and 2) the intervention with the sending of the SMS messages. The outcome variable was the final grade of students. Multivariate models were constructed, prevalence ratios and confidence intervals at 95% were calculated. The first phase revealed that the SMS should be educational-theoretical, motivational, and multiple choice. In the intervention there were 66 participants in the control and intervention group. The average age was 17.7 (± 1.2) years. The intervention group obtained higher scores compared with the control group (PR = 4.82; 95% CI: 1.58 to 14.72). In conclusion, SMS with informative and motivational content is useful in the formation of undergraduate medicine. PMID:26338387

    The study objective was to identify how donors and government agencies in Vietnam responded to donor proliferation in health sector aid between 1995 and 2012. Interviews were conducted with key informants from donor agencies, central government, and civil society in Hanoi in 2012 (n = 34 interviews), identified through OECD Creditor Reporting System data, internet research, and snowball sampling. Interview transcripts were coded for key themes using the constant comparative method. Documentary materials were used in triangulation and validation of key informant accounts. The study identified a timeline of key events and key themes. The number of donors providing health sector aid to Vietnam increased sharply during the late 1990s and early 2000s, then leveled off and declined between 2008 and 2012. Reasons for donor entry included Vietnam's health needs, perceptions of health as less politically sensitive, and donor interests in facilitating market access. Reasons for donor withdrawal included Vietnam's achievement of middle-income status, the global financial crisis, and donors' shifting global priorities. Key themes included high competition among donors, strategic actions by government to increase its control over aid, and the multiplicity of government units involved with health sector aid. The study concludes that central government and donor agencies in Vietnam responded to donor proliferation in health sector aid by endorsing aid effectiveness policies but implementing these policies inconsistently in practice. Whereas previous literature has emphasized donor proliferation's transaction costs, this study finds that the benefits of a large number of less coordinated donors may outweigh the increased administrative costs under certain conditions. In Vietnam, these conditions included relatively high capacity within government, low government dependence on aid, and government interest in receiving diverse donor recommendations.

  12. A comparative study of two communication models in HIV/AIDS coverage in selected Nigerian newspapers

    2013-01-01

    The current overriding thought in HIV/AIDS communication in developing countries is the need for a shift from the cognitive model, which emphasises the decision-making of the individual, to the activity model, which emphasises the context of the individual. In spite of the acknowledged media shift from the cognitive to the activity model in some developing countries, some HIV/AIDS communication scholars have felt otherwise. It was against this background that this study examined the content of some selected Nigerian newspapers to ascertain the attention paid to HIV/AIDS cognitive and activity information. Generally, the study found that Nigerian newspapers had shifted from the cognitive to the activity model of communication in their coverage of HIV/AIDS issues. The findings of the study seem inconsistent with the theoretical argument of some scholars that insufficient attention has been paid by mass media in developing countries to the activity model of HIV/AIDS communication. It is suggested that future research replicate the study for Nigerian and other developing countries’ mass media. PMID:23394854

    We describe how hard-of-hearing (HOH) employees renegotiate both their existing and new group memberships when they acquire and begin to use hearing aids (HAs). Our research setting was longitudinal and we carried out a theory-informed qualitative analysis of multiple qualitative data. When an individual discovers that they have a hearing problem and acquire a HA, their group memberships undergo change. First, HOH employees need to start negotiating their relationship with the HOH group. Second, they need to consider whether they see themselves as members of the disabled or the nondisabled employee group. This negotiation tends to be context-bound, situational, and nonlinear as a process, involving a back-and-forth movement in the way in which HOH employees value different group memberships. The dilemmatic negotiation of new group memberships and the other social aspects involved in HA rehabilitation tend to remain invisible to rehabilitation professionals, occupational healthcare, and employers.

    This study examined the epidemiology of HIV among AI/ANs in Montana. Barriers to HIV testing and motivations to test also were explored. Analysis of data revealed that there were no significant changes in regard to HIV/AIDS case rates, demographic characteristics, or risk behaviors of AI/ANs infected with HIV/AIDS since reporting began in 1985. Barriers to testing included low perception of risk and fear of people finding out about the test. Despite major barriers to testing identified in this study, AI/ANs appeared to be testing at a higher rate than Whites. PMID:21866497

    The HIV/AIDS pandemic threatens economic, social, and environmental sustainability throughout sub-Saharan Africa. This paper reports on a qualitative study exploring interrelationships between HIV/AIDS, labor availability, agricultural productivity, household resources, food consumption, and health status in rural southeastern Uganda. Respondents reported an increase in widow-and-orphan-headed households; labor shortages due to illness and caretaking; degradation of household resources from health-related expenses; loss of land tenure and assets following deaths, especially for widows and orphans; and changes in agricultural practices and productivity. Our study highlights a potential downward spiral of livelihood degradation for vulnerable households and suggests targeted interventions to improve sustainability. PMID:19742210

    Objectives The objectives of the pilot study were to modify existing psychological first aid (PFA) materials so they would be appropriate for use with institutionalized elders, evaluate the feasibility of using nursing home staff to deliver the intervention to residents, and solicit feedback from residents about the intervention. The STORM Study, an acronym for “services for treating older residents’ mental health”, is the first step in the development of an evidence-based disaster mental health intervention for this vulnerable and underserved population. Method Demographic characteristics were collected on participating residents and staff. Program evaluation forms were completed by staff participants during the pilot test and nurse training session. Staff and resident discussion groups were conducted during the pilot test to collect qualitative data on the use of PFA in nursing homes. Results Results demonstrate the feasibility of the PFA program to train staff to provide residents with PFA during disasters. Conclusions Future research should focus on whether PFA improves coping and reduces stress in disaster exposed nursing home residents. PMID:20592947

    The purpose of this paper is to bring to the attention of the AIDS research community the existence of an oral history project known as the Memories of AIDS Project. The project focused on HIV/AIDS support group members, non-governmental organisation (NGO) workers and home-based carers in the Umgungundlovu (Pietermaritzburg) District Municipality, South Africa. The project was carried out by the Sinomlando Centre for Oral History and Memory Work, a research and community development centre of the University of KwaZulu-Natal, over a period of three years (2011-2013). Sixty-five individual oral history interviews of 1 to 4 hours duration and 11 focus group sessions were recorded, transcribed and translated from isiZulu into English when necessary. The life stories of community workers and support group members documented in the interviews show, on the part of the informants, a remarkable degree of agency and assertiveness in matters of sexuality, gender relations and religious beliefs. They found innovative ways of navigating through the conflicting claims of biomedicine, Christianity and African traditional religion. As much as the epidemic caused grief and suffering, it opened the door to new knowledge and new opportunities. PMID:27002356

    Background High-risk surgery patients may lose decision-making capacity as a result of surgical complications. Advance care planning prior to surgery may be beneficial, but remains controversial and is hindered by a lack of appropriate decision aids. This study sought to examine stakeholders’ views on the appropriateness of using decision aids, in general, to support advance care planning among high-risk surgery populations and the design of such a decision aid. Methods Key informants were recruited through purposive and snowball sampling. Semi-structured interviews were conducted by phone until data collected reached theoretical saturation. Key informants were asked to discuss their thoughts about advance care planning and interventions to support advance care planning, particularly for this population. Researchers took de-identified notes that were analyzed for emerging concordant, discordant, and recurrent themes using interpretative phenomenological analysis. Results Key informants described the importance of initiating advance care planning preoperatively, despite potential challenges present in surgical settings. In general, decision aids were viewed as an appropriate approach to support advance care planning for this population. A recipe emerged from the data that outlines tools, ingredients, and tips for success that are needed to design an advance care planning decision aid for high-risk surgical settings. Conclusions Stakeholders supported incorporating advance care planning in high-risk surgical settings and endorsed the appropriateness of using decision aids to do so. Findings will inform the next stages of developing the first advance care planning decision aid for high-risk surgery patients. PMID:25067908

    Dramatic examples of catastrophic damage from an earthquake occurred in 1989, when the M 7.1 Lorna Prieta rocked the San Francisco Bay area, and in 1994, when the M 6.6 Northridge earthquake jolted southern California. The surprising amount and distribution of damage to private property and infrastructure emphasizes the importance of seismic-hazard research in urbanized areas, where the potential for damage and loss of life is greatest. During April 1995, a group of scientists from the U.S. Geological Survey and the University of Tennessee, using an echo-sounding method described below, is collecting data in San Antonio Park, California, to examine the Monte Vista fault which runs through this park. The Monte Vista fault in this vicinity shows evidence of movement within the last 10,000 years or so. The data will give them a "picture" of the subsurface rock deformation near this fault. The data will also be used to help locate a trench that will be dug across the fault by scientists from William Lettis & Associates.

    We report the results of a simulation study in which we explore the joint effect of group absorptive capacity (as the average individual rationality of the group members) and cognitive distance (as the distance between the most rational group member and the rest of the group) on the emergence of collective rationality in groups. We start from empirical results reported in the literature on group rationality as collective group level competence and use data on real-life groups of four and five to validate a mathematical model. We then use this mathematical model to predict group level scores from a variety of possible group configurations (varying both in cognitive distance and average individual rationality). Our results show that both group competence and cognitive distance are necessary conditions for emergent group rationality. Group configurations, in which the groups become more rational than the most rational group member, are groups scoring low on cognitive distance and scoring high on absorptive capacity.

    The incidence of AIDS in French Guiana remains one of the highest in Latin America and the Caribbean. The annual AIDS incidence rate increased continually from the start of the epidemic until 1995, when it reached 59.3/100,000 population declining thereafter to 26.6 in 1997. The prevalence of HIV in pregnant women was 0.9% in 1993, increasing to 1.3% in 1995, and that in individuals attending sexually transmitted disease (STD) clinics was 2.1% in 1996. We included 224 patients in a study of survival after AIDS diagnosis. The principal AIDS-defining diagnosis was tuberculosis in 20.5% of reported cases. The median duration of survival was 10.2 months. Multivariate analysis showed that, patients > or = 45 years at entry progressed more rapidly to AIDS than younger patients. HIV prevention and access to health care should be developed in the various ethnic communities and adapted to cultural status. The progressive implementation of multiple antiretroviral therapies since 1996 may further reduce progression of the disease but early HIV diagnosis is required to improve the overall prognosis of HIV-infected patients.

    The aim of this longitudinal study was to explore whether a hearing aid or noise generator would be an effective audiological treatment for blast-induced chronic tinnitus. The amount of satisfaction from different hearing devices (hearing aid, noise generator, or both) during different time periods (1, 6, 12 and 24 months after fitting) was assessed. The 974 subjects enrolled in this study were Iran-Iraq war veterans, suffering from tinnitus for at least 2 years. About 84% of the subjects preferred just a hearing aid. Only 2.7% chose the noise generator, and the others preferred to use both devices. There were no significant differences between the hearing thresholds of the 3 groups. The satisfaction score for the hearing aid and combined devices increased by time but decreased for the noise generator. There was no correlation between the satisfaction score and parameters such as hearing thresholds, audiogram configuration and tinnitus pitch. We concluded that, compared with a noise generator, the most long-lasting treatment for blast-induced tinnitus is a hearing aid. The possible cause for such a performance is probably the recovery of the auditory function and neuroplasticity through the hearing aid. PMID:25924663

Specifically, we address the reproducibility of Bayesian model comparison (and inferences about model parameters) from three important perspectives namely: (i) reproducibility with independent data (obtained by averaging over odd and even trials); (ii) reproducibility over formally distinct models (namely, classic ERP and canonical microcircuit or CMC models); and (iii) reproducibility over inversion schemes (inversion of the grand average and estimation of group effects using empirical Bayes). Our hope was to illustrate the degree of reproducibility one can expect from DCM when analysing different data, under different models with different analyses. PMID:26733846

    There is increasing evidence for crop cultivation at sites of the Neolithic Swifterbant culture from ca. 4300 B.C. onwards. Presence of cereal fields at the Swifterbant S2, S3 and S4 sites has been corroborated from micro morphological studies of soil samples. Swifterbant sites with evidence for cultivated plants are still scarce though and only emerging, and have produced very low numbers of charred cereals only. The major aim of our work was to elucidate the environmental background of the Dutch Neolithic site Swifterbant S4 based on the investigation of phytolith remains retrieved from soil samples. In addition to find evidence for crop cultivation independently from other studies. Samples were taken at 1 cm intervals vertically from the soil section at the central profile of site S4. Additional samples were taken from pocket-like structures and adjacent horizons above and below. Pig coprolites yielded an astonishing phytolith assemblage which was compared to that of the soil samples. A pig tooth also yielded evaluable material via detailed investigation using SEM. The evaluation of phytolith assemblages retrieved from the soil horizons plus those ending up in the droppings of pigs feasting in the area enabled to draw a relatively reliable environmental picture of the area. All these refer to the presence of a Neolithic horticulture (cereal cultivation) under balanced micro-climatic conditions as a result of the vicinity of the nearby floodplain. These findings corroborate those of previous soil micro-morphological studies.

    Objective Many studies include oral HIV-related endpoints that may be diagnosed by non-oral-health specialists (non-OHS) like nurses or physicians. Our objective was to assess the accuracy of clinical diagnoses of HIV-related oral lesions made by non-OHS compared to diagnoses made by OHS. Methods A5254, a cross-sectional study conducted by the Oral HIV/AIDS Research Alliance within the AIDS Clinical Trial Group, enrolled HIV-1-infected adults participants from six clinical trial units (CTU) in the US (San Francisco, New York, Chapel Hill, Cleveland, Atlanta) and Haiti. CTU examiners (non-OHS) received standardized training on how to perform an oral examination and make clinical diagnoses of specific oral disease endpoints. Diagnoses by calibrated non-OHS were compared to those made by calibrated OHS, and sensitivity and specificity computed. Results Among 324 participants, the majority were black (73%), men (66%), and the median CD4+ cell count 138 cells/mm3. The overall frequency of oral mucosal disease diagnosed by OHS was 43% in US sites, and 90% in Haiti. Oral candidiasis (OC) was detected in 153 (47%) by OHS, with erythematous candidiasis (EC) the most common type (39%) followed by pseudomembranous candidiasis (PC; 26%). The highest prevalence of OC (79%) was among participants in Haiti, and among those with CD4+ cell count ≤ 200 cells/mm3 and HIV-1 RNA > 1000 copies/mL (71%). The sensitivity and specificity of OC diagnoses by non-OHS were 90% and 92% (for EC: 81% and 94%; PC: 82% and 95%). Sensitivity and specificity were also high for KS (87% and 94%, respectively), but sensitivity was < 60% for HL and oral warts in all sites combined. The Candida culture confirmation of OC clinical diagnoses (as defined by ≥ 1 colony forming unit per mL of oral/throat rinse) was ≥ 93% for both PC and EC. Conclusion Trained non-OHS showed high accuracy of clinical diagnoses of OC in comparison with OHS, suggesting their usefulness in studies in resource-poor settings

    This paper describes a case study of a single deaf individual who has been using a vibrotactile aid for approximately 13 years. He has acquired the ability to lip-read speakers in three languages, using the speech-analyzing device that he and his collaborators have developed. The report describes his communicative abilities with and without the aid in his native language, which is Russian, and in English and Hebrew. When he was tested with the De Filippo-Scott connected-discourse tracking technique, the aid produced a considerable improvement in performance over that for unaided lipreading. The amount of improvement was a function of several factors, in particular his unaided lipreading rates for the different languages. PMID:3723423

    Prisons often lack the basic health services required by HIV/AIDS patients. As with many other chronic illnesses, the treatment of HIV is expensive in terms of medication, hygiene, testing and staff training. Strategies to combat the disease have been thoroughly developed, particularly in Europe (WHO/UNAIDS, 2006). The purpose of this study was to assess quality of life (QOL) of the only 5 reported cases of HIV/AIDS patients in Roumieh prison (the country's largest male top-security prison) using the WHOQOL and the WHO guidelines on HIV infection and AIDS in prison. Virtually all prisoners reported that their rights had been violated. Isolation measures were taken to prevent the spread of the disease. According to UNAIDS, this particular measure has been proven ineffective. In conclusion, other approaches should be implemented to respect inmates' rights and reduce transmission of the virus.

    An evaluation is presented which is defined as the adequacy of system design with known functional and performance requirements. The proposed Rockwell International AIDS 3 card, document and data flow are presented to summarize the concepts involved and the relationships between functions. The analysis and evaluation includes a study of system capability, processing rates, search requirements and response accuracy as well as a consideration of operational components and hardware integration. Results indicate that the AIDS 3 System concept is operationally feasible if production capacity is slightly enhanced but that operational complexity, hardware integration and a lack of conceptual data pertinent to some of the functions are areas of concern.

    Objectives This study was designed to assess the knowledge acquired by very young children (<6 years) trained by their own teachers at nursery school. This comparative study assessed the effect of training before the age of 6 years compared with a group of age-matched untrained children. Setting Some schoolteachers were trained by emergency medical teams to perform basic first aid. Participants Eighteen classes comprising 315 pupils were randomly selected: nine classes of trained pupils (cohort C1) and nine classes of untrained pupils (cohort C2). Primary and secondary outcome measures The test involved observing and describing three pictures and using the phone to call the medical emergency centre. Assessment of each child was based on nine criteria, and was performed by the teacher 2 months after completion of first aid training. Results This study concerned 285 pupils: 140 trained and 145 untrained. The majority of trained pupils gave the expected answers for all criteria and reacted appropriately by assessing the situation and alerting emergency services (55.7−89.3% according to the questions). Comparison of the two groups revealed a significantly greater ability of trained pupils to describe an emergency situation (p<0.005) and raise the alert (p<0.0001). Conclusions This study shows the ability of very young children to assimilate basic skills as taught by their own schoolteachers. PMID:25239292

When the telescope is built, an infrastructure will also have been created for energy supply and communications that can be used in subsequent missions. The total mission can be achieved by launching 3 Ariane 5 rockets in the year 2006 configuration that can launch 20,000 kg into GTO. New studies of the construction of even larger telescopes have also been undertaken.. One additional aspect that will be very important is the synergy between humans and robots and their role in transport, construction, operation, maintenance, etc. is addressed in these new studies. Also an attempt will be made to make a parametric cost model for different scenario's as well as the technology readiness levels for the techniques necessary to build a telescope with the capacity of the 'planet finder', equivalent up to 1000 sq m of photon collecting surface. Part of the scenario definition and conceptual design of a large lunar telescope has also been done in the lunar base design workshop, held from 10-21 of June at ESTEC, NL. After the conceptual phase there will be a more engineering oriented workshop, which will be held in the concurrent design facility at ESTEC. This paper includes discussion of recent progress on these studies.

  1. Do Ancillary Studies Aid Detection and Classification of Barrett Esophagus?

    2016-08-01

    Barrett esophagus is a preneoplastic condition defined by the presence of intestinal metaplasia (ie, goblet cells) in an endoscopically apparent columnar-lined esophagus. Dysplasia is the most important risk factor for cancer development among patients with Barrett esophagus; approximately 6% of patients with high-grade dysplasia progress to adenocarcinoma within 1 year. Surgical pathologists are generally expected to address 2 clinical concerns when evaluating mucosal biopsy samples from patients with suspected Barrett esophagus; they should note the presence, or absence, of goblet cells and comment on the grade of dysplasia when it is identified. Biopsy samples from patients with Barrett esophagus are categorized as negative for dysplasia, indefinite for dysplasia, or positive for dysplasia; in the latter situation, the severity of dysplasia is classified as low or high grade. Several histochemical stains, immunohistochemical stains, and molecular techniques can be used to facilitate detection of goblet cells and classify dysplasia in patients with Barrett esophagus, although their added value to routine morphologic assessment is not entirely clear. The purpose of this review is to discuss the state of the art regarding application of ancillary studies to esophageal samples from patients with a columnar-lined esophagus. PMID:27096258

    1990-08-01

    Motion analysis studies require the precise tracking of reference objects in sequential scenes. In a typical situation, events of interest are captured at high frame rates using special cameras, and selected objects or targets are tracked on a frame by frame basis to provide necessary data for motion reconstruction. Tracking is usually done using manual methods which are slow and prone to error. A computer based image analysis system has been developed that performs tracking automatically. The objective of this work was to eliminate the bottleneck due to manual methods in high volume tracking applications such as the analysis of crash test films for the automotive industry. The system has proven to be successful in tracking standard fiducial targets and other objects in crash test scenes. Over 95 percent of target positions which could be located using manual methods can be tracked by the system, with a significant improvement in throughput over manual methods. Future work will focus on the tracking of clusters of targets and on tracking deformable objects such as airbags.

    1974-01-01

    For 6 months details of every patient who had his or her urine sent to a laboratory for bacteriological examination and the result of such examination were entered on a computer-card. A total of 15,606 cards were completed with information in code recording the sex and age of a patient, the origin of the request, the presence or absence in the urine of an excess of protein or cells, the culture result and the name of any significant organism isolated together with its sensitivity to various antimicrobial drugs. This information was interrelated in a computer, and in some cases the resulting numerical details were expressed as rates so as to eliminate the effect of uneven sex and age distribution. In this way the occurrence of urinary tract infection and the type of infecting organism in persons of either sex at various ages was examined according to whether the patient was in hospital or general practice. The sensitivity pattern of each type of significant organism isolated was established according to its source. The association between patients of either sex and various ages who had, or did not have, bacteriologically evident infections and the presence in their urine of an inflammatory exudate was investigated. Finally, the capacity of each type of infecting organism to produce such an exudate was estimated. It was shown that hospital and general practice experience of urinary tract infections differed widely, with regard both to the age and sex distribution of those suffering from it, and to the causative organisms concerned and their sensitivities to antimicrobial drugs. It is suggested that these differences were so great that conclusions drawn from any study of this subject conducted in one of the two areas cannot be applied to the other, and that those derived from a mixture of the two will vary according to the relative sizes of each of the components.

    Various properties of substitutional alloys formed from aluminium and the platinum group metals (PGMs) are examined using density functional (D-F) theory and show strong variations depending on metal type. A similar pattern for the binary alloys is observed using molecular dynamics modeling employing Sutton Chen potentials. All results suggest that several of the PGMs could have superior properties to the presently used Ni3Al alloy for high temperature applications. Some phases are predicted to be stable with extremely high melting temperatures (MTs).

    The development of new pharmaceutical interventions for persons with human immunodeficiency virus (HIV) infection has resulted in extended survival and a need for valid, reliable and responsive instruments to assess health-related QoL (HRQoL). This paper reviews the reliability and validity of an HRQoL instrument, the AIDS Health Assessment Questionnaire (AIDS-HAQ), among persons participating in an observational database of HIV infection. The AIDS-HAQ includes nine subscales: disability, energy, general health, pain, cognitive functioning, mental health, social functioning, health distress and symptoms. Individuals complete the AIDS-HAQ quarterly. Data are reported for 440 individuals entering the study with early HIV infection. Fifty-nine progressed to symptomatic disease and 109 to AIDS after 1 year. The subscales of the instrument resulted in high internal consistency reliability (range = 0.79-0.88). Concurrent validity data reflected the ability to distinguish between patients with increasing disease severity. In all domains, except cognitive functioning, individuals who progressed to AIDS had significant decrements (p < 0.01) in HRQoL compared with symptomatic and asymptomatic patients. Significant decrements (p < 0.01) were observed for disability, general health, energy and symptoms for patients who progressed to symptomatic disease from an asymptomatic status. Individuals who had decreasing CD4+ counts also had significant declines (p < 0.001) in disability, general health, social functioning, pain and symptoms. The AIDS-HAQ is an instrument that can be used when comparing group differences and within group changes in observational databases, naturalistic studies and clinical trials. PMID:9330550

    The qualitative study in this article portrays the couple relationship among AIDS carriers, based on Sternberg's triangular love theory (involving domains of intimacy, passion and commitment). The central study hypothesis is that certain components of the Sternberg model will be more significant than others among the AIDS carrier population. The study was conducted on ten AIDS carriers aged 21-37 who had experienced a couple relationship. Six men and four women participated; most of them were in a romantic couple relationship of homosexual orientation. The interviewees answered a questionnaire that included the three domains-- intimacy, passion and commitment--in the personal interview technique. The interview focused on interviewee's attitude towards his/her relationship with a partner, as he/she understood it. The findings of the study focus on relevant content that was gathered from the interviews and these portray a limited view of couple patterns in the world of AIDS carriers. The study reveals two major findings regarding the carrier's desires: On the one hand, the carrier describes a powerful need for a stable, permanent relationship--from the diagnosis of AIDS and throughout the subsequent years. On the other hand, the carrier also expresses powerful sexual desires that are not necessarily limited to a permanent partner. Thus passion is the dominant among the three domains. The intimacy domain is mainly affected by disclosure of the disease and the joint coping that follows. The findings are discussed in the context of the romantic internalized model theory and Sternberg's triangular love theory. PMID:18923698

    1998-01-01

    The following study investigates the nature of the relationship between physicians and HIV/AIDS patients within the context of the rapidly evolving services/relationship marketing literatures. The emerging evidence suggests that service providers generally play a critical role in the development of positive consumer attitudes and behaviors, and that relationship marketing practices can contribute to the delivery of health services. However, to date, there appears little evidence supporting the efficacy of employing relationship marketing practices in relation to a target market of HIV/AIDS patients. This exploratory study contributes to the body of knowledge by more closely investigating the nature of the patient-physician relationship relative to HIV/AIDS patients' attitudes, marketing-related behaviors, and overall quality-of-life/life satisfaction judgments. The results of this study first suggest that HIV/AIDS patients use the expectancy disconfirmation model when evaluating the performance of their physician. A reliance on expectancy disconfirmation suggests the likely prevalent role of service quality perceptions and satisfaction judgments in evaluating their relationship with their physician. Second, the results appear to support the conclusion that the patient's evaluation of their physician relationship and subsequent behaviors (e.g., word-of-mouth) are directly related to the patient's general perception of received health services. Thus, the patient/physician relationship may play a particularly powerful role in determining patient (marketing related) outcomes relative to other health service settings. Third, a direct influence is supported between negative affective reactions by patients and subsequent outcome behaviors. This finding lends support for the potential efficacy of service recovery efforts when rendering treatment to HIV/AIDS patients. Finally, evidence is presented demonstrating the effect of positive perceptions of the patient

    Objective To evaluate the association of HIV infection and cumulative exposure to highly active antiretroviral therapy (HAART) with the presence and extent of coronary artery calcification (CAC). Design A cross-sectional study of 947 male participants (332 HIV-seronegative, 84 HAART-naive and 531 HAART-experienced HIV-infected) from the Multicenter AIDS Cohort Study. Methods The main outcome was CAC score calculated as the geometric mean of the Agatston scores of two computed tomography replicates. Presence of CAC was defined as calcification score above 10, and extent of CAC by the score for those with CAC present. Multivariable regression was used to evaluate the association between HIV infection and HAART and presence and extent of calcification. Results Increasing age was most strongly associated with both prevalence and extent of CAC for all study groups. After adjustment for age, race, family history, smoking, high-density lipoprotein-C, low-density lipoprotein-C and hypertension, HIV infection (odds ratio, 1.35; 95% confidence interval, 0.70, 2.61) and long-term HAART use (odds ratio, 1.33; 95% confidence interval, 0.87, 2.05) increased the odds for presence of CAC. In contrast, after adjustment for these covariates, the extent of CAC was lower among HAART users. Among those not taking lipid-lowering therapy, HAART usage of at least 8 years was associated with significantly reduced CAC scores (relative CAC score, 0.43; 95% confidence interval, 0.24, 0.79). Conclusion HAART use may have different effects on the presence and extent of coronary calcification. Although prevalence of calcification was marginally increased among long-term HAART users, the extent of calcification was significantly reduced among HAART users compared with HIV-seronegative controls.

    This paper presents the State Department's Interagency Working Group (IWG) model for the spread of HIV. The model is fully operational for Pattern 2 (heterosexual blood transmission) and Pattern 3 (heterosexual, homosexual, and IV drug transmission) countries. This model was developed for various uses, including technical research, policy analysis, and support for decision making. Research uses include studying patterns of HIV spread, assessing the relative effect of different processes on the spread of HIV, examining the demographic impact of HIV infections, and comparing the potential impact of behavioral versus medical intervention strategies. The model will be used in workshops where policy makers and health officials can do hands-on scenario analyses, gain qualitative insights into the possible long-term-epidemiological and demographic impact of HIV, gauge the uncertainties in predictions for the future, and study the impact of HIV, gauge the uncertainties in predictions for the future, and study the impact that intervention strategies are likely to have. The computational model uses a deterministic system of differential equations and runs on a 286- or a 386-based IBM-compatible machine under Microsoft Windows. The program requires an input ASCII (text) file to run; all parameters used by the model are input through this file and, therefore, are user-accessible. The software is user-friendly, mouse-driven, and allows for interactive manipulation of input data and visualization and processing of model outputs. 15 refs., 13 figs., 1 tab.

    Major psychotic disorders are one of the leading causes of disability worldwide. If these conditions are identified early and treatment promptly implemented, the prognosis is improved. This study examined the impact of a yearlong family aided community treatment (FACT) intervention upon psychiatric symptoms. Psychiatric symptom scores improved with the FACT intervention. Improved training on early recognition for mental health clinicians, implementation of a specific treatment model in community settings and policy around treatment funding allocation are implications of this study.

    In our previous work, we demonstrated underutilization of the AIDS Drug Assistance Program (ADAP) at an HIV clinic in Alabama. In order to understand barriers and facilitators to utilization of ADAP, we conducted focus groups of ADAP enrollees. Focus groups were stratified by sex, race, and historical medication possession ratio as a measure of program utilization. We grouped factors according to the social-ecological model. We found that multiple levels of influence, including patient and clinic-related factors, influenced utilization of antiretroviral medications. Patients introduced issues that illustrated high-priority needs for ADAP policy and implementation, suggesting that in order to improve ADAP utilization, the following issues must be addressed: patient transportation, ADAP medication refill schedules and procedures, mailing of medications, and the ADAP recertification process. These findings can inform a strategy of approaches to improve ADAP utilization, which may have widespread implications for ADAP programs across the United States. PMID:24503498

    Objective: The aim of this study was to investigate the shift in the epidemiological features of HIV/AIDS during the last three decades in Fujian Province, southeastern China, so as to provide evidence for the development of novel HIV/AIDS control strategies. Methods: Data pertaining to the conventional surveillance, sentinel surveillance and epidemiological survey in Fujian Province during the period from 1987 to 2015 were collected. The epidemiological trends were described, and the subtypes of HIV strain were genotyped. In addition, the response to antiretroviral therapy was evaluated, and HIV genotypic resistance was assayed. Results: There was an increasing trend observed in the reported cases of HIV/AIDS in Fujian Province. From 1987 to the end of 2015, a total of 8651 HIV/AIDS cases were reported across the province, with totally 1557 deaths found. Among the total cases, the ratio of male/female cases was 3.7:1, which appeared to be an increasing trend; 77.1% cases were detected in young and middle-aged populations aged 19 to 50 years, however, the new HIV infections recently tended to occur in young people aged 15 to 18 years and in populations aged 50 years and older. Among all infected individuals, 49.3% were married, however, the percentage of unmarried cases increased from 6.67% before 1994 to 40.1% in 2015; 64.8% had junior high school education or lower, however, the proportion of HIV/AIDS cases with junior college education or above gradually increased from 6.5% in 2009 to 21.4% in 2015. The reported HIV/AIDS cases were predominantly found in coastal regions; however, a rapidly increasing trend was seen in the number of HIV/AIDS cases in inland regions, and the geographical variation of the cases gradually reduced. There were multiple routes of HIV transmission found in Fujian Province, and 94.2% infections were sexually transmitted, with a large increase in the percentage of male homosexual transmission. A variety of HIV-1 subtypes were genotyped in

    Speechreading ability was investigated among hearing aid users with different time of onset and different degree of hearing loss. Audio-visual and visual-only performance were assessed. One group of subjects had been hearing-impaired for a large part of their lives, and the impairments appeared early in life. The other group of subjects had been impaired for a fewer number of years, and the impairments appeared later in life. Differences between the groups were obtained. There was no significant difference on the audio-visual test between the groups in spite of the fact that the early onset group scored very poorly auditorily. However, the early-onset group performed significantly better on the visual test. It was concluded that the visual information constituted the dominant coding strategy for the early onset group. An interpretation chiefly in terms of early onset may be the most appropriate, since dB loss variations as such are not related to speechreading skill. PMID:8976000

    Recent research has produced disagreement about the usage and usefulness of external memory aids across age groups. The present study examined the use and perceived usefulness of commercial memory aids as a function of the ages of users and potential users. Three age groups (ages 20, 45 and 65 years) were asked to indicate whether they owned each of thirty different commercial aids and regardless of ownership, to rate the degree of usefulness of each of the aids. Each age group used certain aids or perceived certain aids as more useful, than did other age groups. The pattern of results suggest that memory aid usage differs with age partly because the memory tasks required of a person change with life stage. PMID:1761318

    The Center for Epidemiological Studies-Depression (CES-D) scale is a widely used measure of depressive symptoms, but its psychometric properties have not been adequately evaluated among adults with HIV/AIDS. This study used an item response theory approach (Rasch analysis) to evaluate the CES-D's validity and reliability in relation to key demographic and clinical variables in adults with HIV/AIDS. A convenience sample of 347 adults with HIV/AIDS (231 males, 93 females, and 23 transgenders; age range 22–77 years) completed the CES-D. A Rasch model application was used to analyze the CES-D's rating scale functioning, internal scale validity, person-response validity, person-separation validity, internal consistency, differential item functioning (DIF), and differential test functioning. CES-D scores were generally high and associated with several demographic and clinical variables. The CES-D distinguished 3 distinct levels of depression and had acceptable internal consistency but lacked unidimensionality, five items demonstrated poor fit to the model, 15% of the respondents demonstrated poor fit, and eight items demonstrated DIF related to gender, race, or AIDS diagnosis. Removal of misfitting items resulted in minimal improvement in the CES-D's substantive and structural validity. CES-D scores should be interpreted with caution in adults with HIV/AIDS, particularly when comparing scores across gender and racial groups. PMID:27042347

    2010-01-01

    Background Problems with substance use are common in some Aboriginal communities. Although problems with substance use are associated with significant mortality and morbidity, many people who experience them do not seek help. Training in mental health first aid has been shown to be effective in increasing knowledge of symptoms and behaviours associated with seeking help. The current study aimed to develop culturally appropriate guidelines for providing mental health first aid to an Aboriginal or Torres Strait Islander person who is experiencing problem drinking or problem drug use (e.g. abuse or dependence). Methods Twenty-eight Aboriginal health experts participated in two independent Delphi studies (n = 22 problem drinking study, n = 21 problem drug use; 15 participated in both). Panellists were presented with statements about possible first aid actions via online questionnaires and were encouraged to suggest additional actions not covered by the content. Statements were accepted for inclusion in the guidelines if they were endorsed by ≥ 90% of panellists as either 'Essential' or 'Important'. At the end of the two Delphi studies, participants were asked to give feedback on the value of the project and their participation experience. Results From a total of 735 statements presented over two studies, 429 were endorsed (223 problem drinking, 206 problem drug use). Statements were grouped into sections based on common themes (n = 7 problem drinking, n = 8 problem drug use), then written into guideline documents. Participants evaluated the Delphi method employed, and the guidelines developed, as useful and appropriate for Aboriginal and Torres Strait Islander people. Conclusions Aboriginal health experts were able to reach consensus about culturally appropriate first aid for problems with substance use. Many first aid actions endorsed in the current studies were not endorsed in previous international Delphi studies, conducted on problem drinking and problem drug use

    We examined the influence of attitudes concerning HIV transmission, safe sex, and sexual sensation seeking, as well as negotiated risk reduction with primary partners, on the proportion of unprotected sexual partners (%UASP) among men who have sex with men (MSM). Participants were 263 HIV-seropositive and 238 HIV-seronegative MSM in the Multicenter AIDS Cohort Study between 1999 and 2003 who completed a 20-item attitude survey twice. Behavioral data were collected concurrently and 6-12 months after each survey. Among seropositives, decreased HIV concern and increased safer sex fatigue were associated with higher %UASP at 6 and 12 months. Among seronegatives, increased %UASP at 12 months was associated with safer sex fatigue. At 6 months and 12 months, risk reduction agreements were associated with increased %UASP among seronegatives in seroconcordant monogamous relationships, reflecting their abandonment of condoms in such partnerships. We conclude that HIV prevention efforts should target modifiable attitudes (reduced concern about HIV and safer sex fatigue) and increases in sexual risk-taking of MSM, particularly among HIV+ men having sex with serodiscordant partners.

    A quasi-experimental study is reported with four measurement occasions to evaluate longer-term effects of a life-skills and HIV/AIDS school-based prevention program. Trained teachers administered the program promoting precursors of safer sex behavior to 2064 Mexican high-school students at an age before most were sexually active. The variables included in the study (knowledge about HIV/AIDS prevention, attitudes towards use of condoms, subjective norms, intentions to use condoms and life skills as decision-making skills, partner communication and individual responsibility) have been reported as precursors of protective sexual behavior. The results demonstrate the stability of training effects and a positive impact on these precursors over 1 year of follow-up. PMID:18066923

    People living with HIV/AIDS in rural and low HIV prevalence areas face a number of challenges including stigma, limited access to specialized medical care, lack of an HIV/AIDS specialist and fear which may interfere with their ability to find and use information to manage their health. With a large number of HIV cases located in non-metropolitan and rural areas in the US, more research is needed to better understand the health seeking behaviors of individuals living in this context. This study examined how 16 individuals living with HIV sought out information to meet their health needs. In qualitative semi-structured interviews, we explored participants' primary sources of information, types of information sought, and barriers to accessing information. The sample was comprised of people living with HIV/AIDS (PLWHA) who resided in a predominantly rural area with low HIV prevalence. The majority of participants relied on a combination of sources including their HIV/AIDS physician, the Internet, a Ryan-White caseworker and a staff member of a community-based support organization to meet their informational needs. Information sought focused primarily on drug regimens, drug side effects, or drug research. Participants shared barriers to accessing information including stigma, fear, concern about disclosure, and feelings of futility and anger. Findings point to a need to expand health literacy research and interventions to address broader social and structural barriers to health improvement for PLWHA, especially among those living in rural and low HIV prevalence areas.

    Background The emergence of Global Health Initiatives (GHIs) has been a major feature of the aid environment of the last decade. This paper seeks to examine in depth the behaviour of two prominent GHIs in the early stages of their operation in Uganda as well as the responses of the government. Methods The study adopted a qualitative and case study approach to investigate the governance of aid transactions in Uganda. Data sources included documentary review, in-depth and semi-structured interviews and observation of meetings. Agency theory guided the conceptual framework of the study. Results The Ugandan government had a stated preference for donor funding to be channelled through the general or sectoral budgets. Despite this preference, two large GHIs opted to allocate resources and deliver activities through projects with a disease-specific approach. The mixed motives of contributor country governments, recipient country governments and GHI executives produced incentive regimes in conflict between different aid mechanisms. Conclusion Notwithstanding attempts to align and harmonize donor activities, the interests and motives of the various actors (GHIs and different parts of the government) undermine such efforts.

    Enteromorpha is one of the common fouling green algae, which has brought serious environmental problems in past years. This study was aimed to apply it in water treatment process. Enteromorpha polysaccharides (Ep) were used as a new-style coagulant aid to assess its effect on coagulation behavior and floc characteristics. Color removal was used to evaluate coagulation effects and floc properties were investigated by Photometric Dispersion Analyzer (PDA). Results showed that when Ep was used in combination with aluminum chloride (AC), color removal could be apparently improved, and the optimal solution pH ranged 6.0-8.0. The growth rate and average size of flocs formed by AC-Ep were larger than those by AC in steady-state after floc growth phase, and meanwhile the distribution of floc size had a wider range. Besides, floc recoverability could be significantly improved when Ep was used as coagulant aid. PMID:24528717

    Background Guidelines for how a member of the public should give first aid to a person who is becoming psychotic have been developed for English-speaking countries. However, these guidelines may not be appropriate for use in other cultures. A study was therefore carried out to examine whether it was possible to achieve consensus on guidelines that could apply in a range of Asian countries. Methods A Delphi consensus study was carried out with a panel of 28 Asian mental health clinicians drawn from Cambodia, China, Hong Kong, Indonesia, Japan, Malaysia, Mongolia, South Korea, Sri Lanka, Taiwan, Thailand and Vietnam. The panel was given a 211 item questionnaire about possible first aid actions and asked to rate whether they thought these should be included in guidelines. Panel members were invited to propose additional items. Results After three Delphi rounds, there were 128 items that were rated as "essential" or "important" by 80% or more of the panel members. These items covered: recognition of psychosis, encouraging and assisting the person to seek help, how to interact with the person, responding to acute psychosis, responding to aggression, and what to do if the person refuses to get professional help. Conclusion Despite the diversity of the countries involved, there was consensus on a core set of first aid items that were considered as suitable for assisting a psychotic person. Future work is needed to develop guidelines for specific countries. PMID:18291042

    The aviation community is faced with reducing the fatal aircraft accident rate by 80 percent within 10 years. This must be achieved even with ever increasing, traffic and a changing National Airspace System. This is not just an altruistic goal, but a real necessity, if our growing level of commerce is to continue. Honeywell Technology Center's topical study, "Weather Avoidance Using Route Optimization as a Decision Aid", addresses these pressing needs. The goal of this program is to use route optimization and user interface technologies to develop a prototype decision aid for dispatchers and pilots. This decision aid will suggest possible diversions through single or multiple weather hazards and present weather information with a human-centered design. At the conclusion of the program, we will have a laptop prototype decision aid that will be used to demonstrate concepts to industry for integration into commercialized products for dispatchers and/or pilots. With weather a factor in 30% of aircraft accidents, our program will prevent accidents by strategically avoiding weather hazards in flight. By supplying more relevant weather information in a human-centered format along with the tools to generate flight plans around weather, aircraft exposure to weather hazards can be reduced. Our program directly addresses the NASA's five year investment areas of Strategic Weather Information and Weather Operations (simulation/hazard characterization and crew/dispatch/ATChazard monitoring, display, and decision support) (NASA Aeronautics Safety Investment Strategy: Weather Investment Recommendations, April 15, 1997). This program is comprised of two phases, Phase I concluded December 31, 1998. This first phase defined weather data requirements, lateral routing algorithms, an conceptual displays for a user-centered design. Phase II runs from January 1999 through September 1999. The second phase integrates vertical routing into the lateral optimizer and combines the user

    Introduction Reported first aid application, frequency and practices around the world vary greatly. Based primarily on animal and observational studies, first aid after a burn injury is considered to be integral in reducing scar and infection, and the need for surgery. The current recommendation for optimum first aid after burn is water cooling for 20 minutes within three hours. However, compliance with this guideline is reported as poor to moderate at best and evidence exists to suggest that overcooling can be detrimental. This prospective cohort study of a bi-national burn patient registry examined data collected between 2009 and 2012. The aim of the study was to quantify the magnitude of effects of water cooling first aid after burn on indicators of burn severity in a large human cohort. Method The data for the analysis was provided by the Burn Registry of Australia and New Zealand (BRANZ). The application of first aid cooling prior to admission to a dedicated burn service, was analysed for its influence on four outcomes related to injury severity. The patient related outcomes were whether graft surgery occurred, and death while the health system (cost) outcomes included total hospital length of stay and admission to ICU. Robust regression analysis using bootstrapped estimation adjusted using a propensity score was used to control for confounding and to estimate the strength of association with first aid. Dose-response relationships were examined to determine associations with duration of first aid. The influence of covariates on the impact of first aid was assessed. Results Cooling was provided before Burn Centre admission for 68% of patients, with at least twenty minutes duration for 46%. The results indicated a reduction in burn injury severity associated with first aid. Patients probability for graft surgery fell by 0.070 from 0.537 (13% reduction) (p = 0.014). The probability for ICU admission fell by 0.084 from 0.175 (48% reduction) (p<0.001) and hospital

    It is known that the level of HIV/AIDS-related knowledge and the degree of condom use varies by socioeconomic status (SES). However, there is limited research on the effect of mass media use on HIV/AIDS-related cognitive and behavioral outcomes in low-income countries and how it might influence the association between SES and HIV-related outcomes. We investigated the moderating effect of media use on the relationship between SES and HIV/AIDS-related knowledge and condom use in sub-Saharan Africa in terms of communication inequalities. Cross-sectional data from the Demographic Health Surveys from 13 sub-Saharan countries (2004-10) were pooled. Gender-stratified multivariable poisson regression of 151,209 women and 68,890 men were used to calculate adjusted relative ratios and 95% confidence intervals for the associations between SES, media use, HIV-related outcomes, and condom use. We found significant disparities in mass media use among people from different SES groups as well as among countries. Education and wealth are strongly and positively associated with awareness of HIV/AIDS and knowledge about transmission and prevention of HIV/AIDS and are significantly associated with condom use. These associations are attenuated when the use of various types of mass media is added to the models, with newspapers showing the strongest effect. The findings of this study suggest that media use has the potential to blunt the impact of socioeconomic status though not completely eliminate it. Thus, we need to pay attention to reducing communication inequalities among social groups and countries to moderate the effect of wealth and SES on HIV/AIDS. PMID:23874598

    To examine the association between demographic characteristics and long-term smoking trajectory group membership among HIV-seropositive and HIV-seronegative men who have sex with men (MSM). A cohort of 6552 MSM from the Multicenter AIDS Cohort Study were asked detailed information about their smoking history since their last follow-up. Group-based trajectory modeling was used to examine smoking behavior and identify trajectory group membership. Because participants enrolled after 2001 were more likely to be younger, HIV-seronegative, non-Hispanic black, and have a high school diploma or less, we also assessed time of enrollment in our analysis. Participants were grouped into 4 distinct smoking trajectory groups: persistent nonsmoker (n = 3737 [55.9 %]), persistent light smoker (n = 663 [11.0 %]), heavy smoker to nonsmoker (n = 531 [10.0 %]), and persistent heavy smoker (n = 1604 [23.1 %]). Compared with persistent nonsmokers, persistent heavy smokers were associated with being enrolled in 2001 and later (adjusted odds ratio [aOR] 2.35; 95 % CI 2.12-2.58), having a high school diploma or less (aOR 3.22; 95 % CI 3.05-3.39), and being HIV-seropositive (aOR 1.17; 95 % CI 1.01-1.34). These associations were statistically significant across all trajectory groups for time of enrollment and education but not for HIV serostatus. The overall decrease of smoking as shown by our trajectory groups is consistent with the national trend. Characteristics associated with smoking group trajectory membership should be considered in the development of targeted smoking cessation interventions among MSM and people living with HIV.

    Background: The introduction of antiretroviral therapy has caused a remarkable decrease in the occurrence of diseases and mortality among HIV-positive patients, while this success has not been achieved among injection addicts due to a low adherence to antiretroviral medicine. This study aims at clarifying the important factors affecting adherence to treatment in addicts suffering from HIV. Materials and Methods: In this qualitative research, data were gathered through in-depth interviews and field notes, and were interpreted through content analysis in the form of constant comparison. The participants were 16 drug addicts living with HIV/AIDS. Most of them had records of imprisonment and were receiving Highly Active Antiretroviral Therapy (HAART) drug treatments in the AIDS center of Imam Khomeini Hospital complex, affiliated to Tehran University of Medical Sciences. Sampling was started in a purposive method and was continued until data were saturated. Results: Four main categories including psychological reactions, contradictory beliefs, perceived support, and individual and environmental barriers were extracted from the data, each having some sub-categories. Conclusions: The obtained results indicated that adherence to the treatment of HIV is not constant and mono-dimensional, but is a function of different factors. Hence, an individual having feeble adherence in a specific time and under specific circumstances may show desirable adherence under a different circumstance. Thus, treatment of addicts living with HIV/AIDS requires physical, psychological, and social attention along with drug treatments. PMID:26985220

    The purpose of this study was to examine the effect of an age-specific AIDS education program on HIV/AIDS knowledge, perceived susceptibility to AIDS, and perceived severity of AIDS in older adults. The health belief model served as a framework. The age-specific AIDS education program was developed based on a knowledge, beliefs, and behaviors survey of 458 older adults at senior citizen centers. The program included case study presentations of actual older people with AIDS along with an emphasis on myths identified in the initial survey. There was a significant increase in total knowledge about AIDS (p < .001), perceived susceptibility (p < .01), and perceived severity (p < .001) after the educational program. Based on the results of this study, nurses are in an excellent position to provide primary and secondary AIDS prevention strategies for all age groups, including the older adult population.

    2014-01-01

    Background Unintentional injuries are a major cause of death among children. Data suggest that the retention of knowledge and skills about first aid declined over time. The purpose of this study was to assess the effects of pediatric first aid training among teachers. Methods A stratified random sampling method was used to select 1,067 teachers. The selected trainees received pediatric first aid training. Follow-up assessments were conducted 6 months, 9 months and 4 years following the training. A standardized collection of demographics was performed, and participants were given a questionnaire to indicate knowledge of and emotions about first aid. Results In the pretest, 1067 people responded with a mean of 21.0 correct answers to 37 questions, whereas in the post-test period, the mean score increased to 32.2 correct answers of 37 questions (P <0.001). There was a decrease in scores from post-test to 6 months, 9 months and 4 years after the training. However, the mean at the 6-month, 9-month and 4-year marks were higher than the pretest mean (P < 0.001). A total of 82.8% of the participants achieved a pass mark of 80% or above; 42.8% of participants achieved the pass mark at 6 months, 41.7% at 9 months and 11.7% at 4 years (compared with pre-test, P < 0.001). The mean score of the subjects’ emotions in the post-test period increased to 81 (P < 0.001). The mean scores of emotions at 9 months or 4 years were higher than the pretest mean (P < 0.001). At the 4-year mark, the majority of preschool staff (>70%) had administered correct first aid for injuries. Conclusions This study demonstrated that the acquisition of knowledge, both short and long term, significantly improves. Despite appreciable decreases in knowledge long term, knowledge retention was modest but stable. PMID:25152013

    2013-01-01

    Background Clinicians face challenges in promoting colorectal cancer screening due to multiple competing demands. A decision aid that clarifies patient preferences and improves decision quality can aid shared decision making and be effective at increasing colorectal cancer screening rates. However, exactly how such an intervention improves shared decision making is unclear. This study, funded by the National Cancer Institute, seeks to provide detailed understanding of how an interactive decision aid that elicits patient’s risks and preferences impacts patient-clinician communication and shared decision making, and ultimately colorectal cancer screening adherence. Methods/Design This is a two-armed single-blinded randomized controlled trial with the target of 300 patients per arm. The setting is eleven community and three academic primary care practices in Metro Detroit. Patients are men and women aged between 50 and 75 years who are not up to date on colorectal cancer screening. ColoDATES Web (intervention arm), a decision aid that incorporates interactive personal risk assessment and preference clarification tools, is compared to a non-interactive website that matches ColoDATES Web in content but does not contain interactive tools (control arm). Primary outcomes are patient uptake of colorectal cancer screening; patient decision quality (knowledge, preference clarification, intent); clinician’s degree of shared decision making; and patient-clinician concordance in the screening test chosen. Secondary outcome incorporates a Structural Equation Modeling approach to understand the mechanism of the causal pathway and test the validity of the proposed conceptual model based on Theory of Planned Behavior. Clinicians and those performing the analysis are blinded to arms. Discussion The central hypothesis is that ColoDATES Web will improve colorectal cancer screening adherence through improvement in patient behavioral factors, shared decision making between the

    The Mini-Sosie high-resolution seismic method has been effective in imaging shallow-structure and stratigraphic features that aid in seismic-hazard and neotectonic studies. The method is not an alternative to Vibroseis acquisition for large-scale studies. However, it has two major advantages over Vibroseis as it is being used by the USGS in its seismic-hazards program. First, the sources are extremely portable and can be used in both rural and urban environments. Second, the shifting-and-summation process during acquisition improves the signal-to-noise ratio and cancels out seismic noise sources such as cars and pedestrians. -from Authors

    A review of projects run by non-governmental organizations (NGOs) in primarily developing countries, which have aimed to provide STD/AIDS education and prevention skills to various marginalized groups, reveals that past quantitative and formative research has failed to identify key programmatic factors which lead to more successful project implementation and sustainability. In observations, interviews with field staff, visits to program sites and information drawn from the literature, a variety of methods to reach a wide range of groups such as men who have sex with men, prostitutes, clients of prostitutes, prisoners, street children, migrant workers and refugees are explored. Factors found to facilitate project success include the following: at least one full-time committed staff member; respectful treatment and appropriate motivation of the target group; suitable and sufficient equipment and supplies (particularly condoms); planning ahead for the participation of HIV-positive individuals and ways to meet their needs; focusing on qualitative rather than quantitative evaluation; planning in advance beyond a 9 or 12 month 'model'. Despite some evidence that marginalized groups can be successfully motivated to practise safer sex through prevention education, long-term behaviour change still presents major challenges--even when specific conditions are met.

    AIDS-related knowledge and behaviours among students at the Gondar College of Medical Sciences, Gondar, Ethiopia were evaluated based on identical surveys conducted in 1990 and 1992. One hundred three second year students provided information in 1992. Analysis indicated that 49% were engaged in sexual intercourse and only a third of these group used condom despite their improved knowledge and belief on condom compared to their previous position in 1990 (p < 0.004). On the other hand, their sexual behaviours regarding sexual contact with high risk individuals decreased compared to 1990 (p < 0.0005). Their general level of AIDS-related preventive knowledge increased over time (p < 0.002), although there was no significant difference in knowledge observed among different sexes and departments. Among the sexually active, a large proportion of students (22%) still had sexual contact with high risk individuals and only 33% of them were using safer methods. Continuing efforts, including peer education, specific health education interventions are still crucially needed to bring a positive change in sexual behaviour. PMID:9558757

    Various forms of distant healing (DH), including prayer and "psychic healing," are widely practiced, but insufficient formal research has been done to indicate whether such efforts actually affect health. We report on a double-blind randomized trial of DH in 40 patients with advanced AIDS. Subjects were pair-matched for age, CD4+ count, and number of AIDS-defining illnesses and randomly selected to either 10 weeks of DH treatment or a control group. DH treatment was performed by self-identified healers representing many different healing and spiritual traditions. Healers were located throughout the United States during the study, and subjects and healers never met. Subjects were assessed by psychometric testing and blood draw at enrollment and followed for 6 months. At 6 months, a blind medical chart review found that treatment subjects acquired significantly fewer new AIDS-defining illnesses (0.1 versus 0.6 per patient, P = 0.04), had lower illness severity (severity score 0.8 versus 2.65, P = 0.03), and required significantly fewer doctor visits (9.2 versus 13.0, P = 0.01), fewer hospitalizations (0.15 versus 0.6, P = 0.04), and fewer days of hospitalization (0.5 versus 3.4, P = 0.04). Treated subjects also showed significantly improved mood compared with controls (Profile of Mood States score -26 versus 14, P = 0.02). There were no significant differences in CD4+ counts. These data support the possibility of a DH effect in AIDS and suggest the value of further research. PMID:9866433

    Despite a growing body of research on employee voice—defined as the discretionary communication of ideas, suggestions, or opinions intended to improve organizational or unit functioning—the effects of shared or collective-level cognitions have received scant attention. There has also been relatively little research on voice within work groups. Our goal in this study was to address these important gaps by focusing on the effects of group-level beliefs about voice (i.e., group voice climate) on individual voice behavior within work groups. We conducted a cross-level investigation of voice behavior within 42 groups of engineers from a large chemical company. Consistent with our hypotheses, group voice climate was highly predictive of voice and explained variance beyond the effects of individual-level identification and satisfaction, and procedural justice climate. Also consistent with predictions, the effect of identification on voice was stronger in groups with favorable voice climates. These findings provide evidence that voice is shaped not just by individual attitudes and perceptions of the work context, as past research has shown, but also by group-level beliefs. The results also highlight the importance of broadening our conceptual models of voice to include shared cognitions and of conducting additional cross-level research on voice. PMID:20718517

    This study is based on interviews conducted among 8 women's income-generating groups and 12 individual women entrepreneurs in 15 villages in Masaka district, Uganda. The Baganda are the main tribe in the study villages. The study evaluates the economic achievement, objectives, and social characteristics of the groups. Groups ranged in size from 9-20 members. All had functioned for 3-5 years. A regular membership fee was paid through the sale of agricultural produce. Groups met at least every 2 weeks. This study revealed that the individual goals were to increase individual wealth, while the stated group goals were to invest in the community. Members considered the groups as useful in providing an easy way to raise capital. Most members considered financial status as a criterion for group membership. Elderly women tended to join social and handicraft groups. The women's group members tended to be friends before the establishment of the group and tended to be currently married to men residing in the area. Of the 12 women entrepreneurs, only 5 were currently married. All 12 women entrepreneurs had considerable initiative. The 12 women and the women's group members derived income from two or more sources: agricultural projects, animal husbandry, craft production, alcohol production and sale, or other activities. Study findings indicate that decisions were often delayed or avoided in order to preserve social cohesion. In a market-oriented enterprise, quick response time is needed and the bureaucratic dynamics would hinder some agricultural ventures. The poorest women experienced barriers to group membership. Women entrepreneurs were more successful than group women. PMID:12347716

Study Looking at End Expiratory Pressure for Altitude Illness Decrease (SLEEP-AID). High Alt Med Biol 16:154-161, 2015.--Acute mountain sickness (AMS) affects 25%-70% of the tens of millions of high altitude travelers annually, with hypoxia and nocturnal desaturations as major contributing factors. This is the first double blind randomized placebo controlled trial to assess expiratory positive airway pressure (EPAP) for AMS prevention and nocturnal hypoxic events. Healthy adult participants trekking in the Khumbu region of the Himalayas were randomized to a single-use EPAP nasal strip, or a visually identical sham device (placebo) prior to first night sleeping between 4371-4530 m (14,340-14,800 ft). The primary outcome was AMS incidence, measured by Lake Louise Questionnaire (LLQ), with secondary outcomes of AMS severity (by LLQ) and physiologic sleep indices measured by continuous sleep monitor. Intent-to-treat analysis included 219 participants with comparable demographic characteristics, of which 115 received EPAP and 104 placebo. There was no decrease in AMS with EPAP intervention (14% EPAP vs. 17% placebo; p=0.65; risk difference (-)3.15%, 95% CI (-)12.85%-6.56%). While overall AMS severity was not different between groups, EPAP reported decreased incidence of headache (64% vs. 76%; p<0.05, OR 0.51, 95% CI 0.27-0.95) and dizziness (81% vs. 98%; p<0.03, OR 0.29, 95% CI 0.09-0.78). During sleep, EPAP resulted in significant improvements in average peripheral oxygenation (Spo(2)) (80% versus 78%; p<0.01, mean difference=2, 95% CI 0.58-3.63) and a reduced percentage of time below 80% Spo(2) (31% vs. 46%; p<0.03, median difference=16, 95% CI 2.22-28.18).

    This case study illustrates a participatory framework for confronting critical community health issues using 'grass-roots' research-guided community-defined interventions. Ongoing work in Cambodia has culturally adapted research, theory and practice for particular, local health-promotion responses to HIV/AIDS, alcohol abuse and other challenges in the community of Siem Reap. For resource-poor communities in Cambodia, we recycle such 'older' concepts as 'empowerment' and 'action research'. We re-imagine community health psychology, when confronted with 'critical', life-and-death issues, as adjusting its research and practices to local, particular ontological and epistemological urgencies of trauma, morbidity and mortality.

    Testing for antibody to human T-lymphotropic retrovirus (HTLV-III) was carried out in 448 participants in the Vancouver Lymphadenopathy-AIDS (acquired immune deficiency syndrome) Study. The overall prevalence rate of seropositivity was 34%. Of 130 seronegative subjects followed for an average of 8.5 months, 14 became seropositive; thus, the approximate annual seroconversion rate was 15%. More than 100 male sexual partners in one's lifetime, frequent receptive anal intercourse, fisting, a history of gonorrhea or hepatitis, and frequent sexual contact in clubs were found to be independent risk factors for HTLV-III seropositivity.

    Behavior change can curtail the spread of acquired immune deficiency syndrome (AIDS). In this study, 104 gay men with a history of frequent AIDS high-risk behavior completed self-report, self-monitoring, and behavioral measures related to AIDS risk. The sample was randomly divided into experimental and waiting-list control groups. The experimental intervention provided AIDS risk education, cognitive-behavioral self-management training, sexual assertion training, and attention to the development of steady and self-affirming social supports. Experimental group participants greatly reduced their frequency of high-risk sexual practices and increased behavioral skills for refusing sexual coercions, AIDS risk knowledge, and adoption of "safer sex" practices. Change was maintained at the 8-month follow-up. PMID:2925974

    OBJECTIVES To determine associations between intertwining epidemics (syndemics) and HIV medication adherence and viral load levels among HIV-positive men who have sex with men (MSM); and to test whether adherence mediates the relationship between syndemics and viral load. DESIGN We analyzed participant data collected between 2003—2009 from the Multicenter AIDS Cohort Study, a prospective HIV/AIDS cohort study in four U.S. cities. METHODS We conducted longitudinal analyses (repeated measures mixed models) to assess if differences in viral load levels, undetectable viral load, and self-reported HIV medication adherence were associated with count of syndemic conditions (substance use, depression symptoms, and sexual risk behavior, range 0 to 3), adjusting for race/ethnicity, age, and income. Mediation analyses were conducted using structural equation modeling and the SAS %mediate macro. RESULTS Syndemics count was associated with higher viral loads (p<.0001) and lower adherence (p<.0001). Increased counts of concomitant syndemics were associated with viral load (p <.01), detectable viral load (p <.05), and adherence (p <.001). Black MSM experienced worse outcomes across domains than White MSM (p <.0001) and experienced higher overall rates of syndemics (p<.01). Adherence significantly mediated the relationship between syndemics and viral load, accounting for an estimated 32.3% of the effect (p<.05). CONCLUSIONS Effectively lowering viral load levels among MSM has implications for both HIV/AIDS prevention and care. Our findings suggest that integrating substance use interventions, mental health care, and sexual risk prevention into standard HIV care may be necessary to optimize treatment and Treatment as Prevention (TasP) models.

  19. Going public as an AIDS family caregiver.

    Powell-Cope, G M; Brown, M A

    1992-03-01

    Images of AIDS invoke fears of contagion, disability and formidable death, and moral overtones directed toward drug use, sexuality and sexual identity and freedom. Responses to these images are both private and public, and have profound consequences for individuals whose lives have been touched by the disease, both the person with AIDS and the family caregiver. The purpose of this paper is to analyze in detail 'going public,' one category of a substantive theory of AIDS family caregiving. This category was developed from a grounded theory study of 53 AIDS family members who were asked to describe their experiences as an AIDS family caregiver during an indepth interview. Data were content analyzed using constant comparative analysis. Going public referred to how AIDS family caregivers let others known that they were caring for a PWA. Specifically, going public entailed selecting appropriate persons and audiences to tell, formulating approaches to communicating information, and considering the risks and benefits of the possible choices. The description of going public as an AIDS family caregiver details the assertiveness involved in political action and social change, contrasted with the isolation and secrecy involved in maintaining relationships with others under the condition of a stigmatizing illness. Data revealed a particular emphasis on the phenomenon of 'guilt by association'. Because of their close relationship to a person with AIDS, caregivers were obligated to share the stigma of AIDS and were likewise discredited. Findings from our study emphasize the tremendous personal suffering experienced by caregivers which was associated with AIDS stigma in the form of rejection, loss of friends and harassment. Data also revealed the strong commitment of many caregivers to social activism which ranged from participating in educational efforts to marching in demonstrations. The rationale for the apparent increased activism among AIDS family caregivers compared to

    This paper describes an empirical investigation of the effect of three dimensional (3-D) imaging on group performance in a tactical planning task. The objective of the study is to examine the role that stereoscopic imaging can play in supporting face-to-face group problem solving and decision making-in particular, the alternative generation and evaluation processes in teams. It was hypothesized that with the stereoscopic display, group members would better visualize the information concerning the task environment, producing open communication and information exchanges. The experimental setting was a tactical command and control task, and the quality of the decisions and nature of the group decision process were investigated with three treatments: 1) noncomputerized, i.e., topographic maps with depth cues; 2) two-dimensional (2-D) imaging; and 3) stereoscopic imaging. The results were mixed on group performance. However, those groups with the stereoscopic displays generated more alternatives and spent less time on evaluation. In addition, the stereoscopic decision aid did not interfere with the group problem solving and decision-making processes. The paper concludes with a discussion of potential benefits, and the need to resolve demonstrated weaknesses of the technology. PMID:11541531

    Objectives Fertility desires require new understanding in a context of expanding access to antiretroviral therapy for people living with HIV/AIDS in Sub-Saharan Africa. This paper studies the fertility desires and their rationales, of slum-dwelling Kenyan men and women living with HIV/AIDS who know their serostatus, but have different antiretroviral therapy treatment statuses. It addresses two research questions: How do people living with HIV/AIDS consider their future fertility? What factors contribute to an explanation of fertility desires among people living with HIV/AIDS. Methods A mixed methods study (survey [n = 513] and in-depth interviews [n = 41]) with adults living with HIV/AIDS living in Nairobi slums was conducted in 2010. Regression analyses assess independent relationships between fertility desires and socio-demographic factors. Analyses of in-depth interviews are used to interpret the statistical analyses of fertility desires. Results Our analyses show that fertility desires are complex and ambivalent, reflecting tensions between familial and societal pressures to have children versus pressures for HIV (re-)infection prevention. More than a third (34%) of men and women living with HIV expressed future fertility desires; however, this is significantly lower than in the general population. Factors independently associated with desiring a child among people living with HIV/AIDS were age, sex, number of surviving children, social support and household wealth of the respondent. Discussion Increasing access to ART is changing the context of future childbearing for people living with HIV/AIDS. Prevailing values mean that, for many people living with HIV/AIDS, having children is seen as necessary for a “normal” and healthy adult life. However, the social rewards of childbearing conflict with moral imperatives of HIV prevention, presenting dilemmas about the “proper” reproductive behaviour of people living with HIV/AIDS.

    Normal-hearing listeners use acoustic cues in speech to interpret a speaker's emotional state. This study investigates the effect of hearing aids on the perception of the emotion dimensions arousal (aroused/calm) and valence (positive/negative attitude) in older adults with hearing loss. More specifically, we investigate whether wearing a hearing aid improves the correlation between affect ratings and affect-related acoustic parameters. To that end, affect ratings by 23 hearing-aid users were compared for aided and unaided listening. Moreover, these ratings were compared to the ratings by an age-matched group of 22 participants with age-normal hearing.For arousal, hearing-aid users rated utterances as generally more aroused in the aided than in the unaided condition. Intensity differences were the strongest indictor of degree of arousal. Among the hearing-aid users, those with poorer hearing used additional prosodic cues (i.e., tempo and pitch) for their arousal ratings, compared to those with relatively good hearing. For valence, pitch was the only acoustic cue that was associated with valence. Neither listening condition nor hearing loss severity (differences among the hearing-aid users) influenced affect ratings or the use of affect-related acoustic parameters. Compared to the normal-hearing reference group, ratings of hearing-aid users in the aided condition did not generally differ in both emotion dimensions. However, hearing-aid users were more sensitive to intensity differences in their arousal ratings than the normal-hearing participants.We conclude that the use of hearing aids is important for the rehabilitation of affect perception and particularly influences the interpretation of arousal.

    AIDS educational programs can be effective only to the extent that they are perceived as credible by their target audiences. In this study, public trust associated with AIDS was assessed in a national telephone survey. African-Americans were more likely than whites to express distrust of doctors and scientists concerning HIV transmission through casual contact, to believe that AIDS is being used as a form of genocide against minority groups, and to believe that information about AIDS is being withheld from the public. Individuals high in distrust did not differ from those low in distrust in their exposure to AIDS information. Higher levels of AIDS-related distrust were not related to self-reported personal risk reduction, but were related to inaccurate beliefs about HIV transmission through casual contact and greater willingness to avoid and stigmatize people with AIDS. The importance of overcoming distrust in AIDS education programs is discussed. PMID:7986656

    Interviews regarding medical history, life-style, specific drug taking and sexual activities, and physical examinations were administered to 4,955 homosexual men who volunteered for the Multicenter AIDS Cohort Study in Baltimore, Chicago, Los Angeles, and Pittsburgh. Overall, the prevalence of antibodies to human immunodeficiency virus (HIV) in these men was 38.0%. The factor most strongly associated with prevalent HIV infection according to a multiple logistic regression model was rectal trauma, a composite variable which included receptive anal fisting, enemas before sex, reporting of blood around the rectum, and the observation of scarring, fissures or fistulas on rectal examination. Receptive anal intercourse also was strongly associated with HIV infection in the model. The multivariate relative odds for HIV antibody positivity was 7.72 for the highest level of rectal trauma and 3.04 for receptive anal intercourse. Symptoms reported to occur in some persons who subsequently develop acquired immunodeficiency syndrome (AIDS) were frequent among HIV seropositive men (12.9%) but were reported in 8.4% of seronegative men as well. Generalized lymphadenopathy was observed significantly more often in seropositive men (48.8%) compared with seronegative men (11.4%). The prevalence of HIV antibodies was inversely related to the number of T-helper cells and directly related (to a lesser extent) to the number of T-suppressor cells. The results suggest that disruption of the rectal mucosa provides access by HIV to the blood stream and to specific immunologic cells. Since symptoms and generalized lymphadenopathy were often reported among seronegative men, they probably also occur among some seropositive men not currently progressing to AIDS. PMID:3651095

    Since the development of the welfare state, the Swedish school subject Health and Physical Education (HPE) has been regarded as an important site for public health work, and still assumes a central role in promoting the health of the coming generation. A specific type of health intervention, promoted by researchers in recent years, is the use of so-called exergames. In some countries, these fitness games are used as teaching aids in physical education classes and can be seen as examples of how public health issues and popular culture are shaping HPE in schools. The aim of the study reported in this paper is to examine which messages about health and body are offered, and how these are expressed in some of the fitness games used as teaching aids in school. The results of the study highlight the dangers of using exergames in the teaching of HPE in schools. The messages communicated by the games have a number of potentially harmful consequences, particularly with regard to the creation of specific health and bodily norms based on a measurable ideal. The use of this tool in education is thus far from value free, and the problems that might be solved when using the games are not necessarily the ones that education should privilege. PMID:26740738

    One of the primary goals of computer-aided ergonomics is to develop software tools that allow ergonomics information to be accessed at the earliest stages of design. This case study discusses a PC-based software program that allows a designer to quantify a worker's biomechanical risk for injury based on a proposed workplace design. The program couples an established software tool for biomechanical analysis, the Three-Dimensional Static Strength Prediction Program (3DSSPP), with a widely used computer-aided design software package, AutoCAD. The use of this "3DSSPP/AutoCAD interface" in the proactive analysis of an automotive assembly task is described and the results compared with an independent assessment using observations of workers performing the same task. Both studies yield similar conclusions, suggesting that proactive use of software such as the 3DSSPP/AutoCAD interface may be a valid tool in evaluating proposed workplace designs. In this context, issues in the analysis of workplace designs regarding the use of supporting ergonomic tools, assumptions, and posture selection are discussed. PMID:10855452

    Religious group identification is an important but understudied social identity. The present study investigates religious group identification among adolescents of different faiths (Hindu, Muslim, Christian) living in multicultural Mauritius. It further explores how religious and national group identities come together among religious majority and minority adolescents. For three age groups (11 to 19 years, N = 2152) we examined the strength of adolescents' religious and national group identification, the associations between these two identities, and the relationships to global self-esteem. Across age and religious group, participants reported stronger identification with their religious group than with the nation. Identification with both categories declined with age, with the exception of Muslims, whose strong religious identification was found across adolescence. The association between religious and national identification was positive, albeit stronger for the majority group of Hindus and for early adolescents. We examined the manner in which religious and national identities come together using a direct self-identification measure and by combining the separate continuous measures of identification. Four distinct clusters of identification (predominant religious identifiers, dual identifiers, neutrals, and separate individuals) that were differently associated with global self-esteem were found. Dual identifiers reported the highest level of global self-esteem. The clusters of identification did not fully correspond to the findings for the direct self-identification measure. The results are discussed in terms of the meaning of dual identity and the positive manner in which adolescents can manage their multiple identities while taking into account the ideological framework in which those identities are played out.

    This study evaluated the effectiveness of a group mentoring program that included components of empirically supported mentoring and cognitive behavioral techniques for children served at a community mental health center. Eighty-six 8- to 12-year-old children were randomly assigned to either group mentoring or a wait-list control group. Group mentoring significantly increased children’s reported social problem-solving skills and decreased parent-reported child externalizing and internalizing behavior problems after controlling for other concurrent mental health services. Attrition from the group mentoring program was notably low (7%) for children. The integration of a cognitive behavioral group mentoring program into children’s existing community mental health services may result in additional reductions in externalizing and internalizing behavior problems.

    In Latin America, transgender women (transwomen or male to female transgenders) have been included in MSM research but without addressing their specific needs in terms of the HIV/AIDS. We present results of the first seroepidemiologic study designed for transwomen in Peru. We conducted a study using respondent driven sampling to recruit transwomen from Lima. Our survey explored sociodemographic characteristics, gender enhancement procedures and sexual behavior. In addition, we conducted laboratory based HIV, genital herpes (HSV2) and syphilis testing. A total of 450 transwomen were recruited between April and July 2009. HIV prevalence was 30%, HSV2: 79% and syphilis: 23%. Sex-work was the main economic activity (64%). Gender enhancement procedures were reported by 70% of the population. Multivariable analysis showed HIV infection to be associated with being older than 35 recent, syphilis infection and HSV2 infection. Transwomen are the group most vulnerable to HIV/AIDS in Peru.

    Background Group practices are increasingly common for primary care physicians worldwide. Although breakups are likely to happen frequently within group practices, their process has not been studied to date. The aims of this study were therefore to explore the reasons for breakups of group practices of general practitioners and to describe the associated feelings. Methods We conducted a qualitative study consisting of in-depth interviews of 21 general practitioners and one secretary from past group practices in the Rhône-Alpes region, France, who experienced a breakup. Results When getting started in group practice for the first time, young doctors did not feel ready and supported, and did not necessarily share the same expectations as their partners. The reasons for the breakups involved imbalances within the groups, contrasting working and management styles, and breakdowns in communication. The breakup process often generated long-persistent feelings of suffering and failure for almost every partner who experienced a breakup, particularly for the partner who was leaving. Conclusions Weakening factors exist from the very beginning of a partnership, and problems are likely to increase at every change or event occurring in the group. We provide several recommendations, including fair management, a shared project based on a precise contract, the consultation of third parties as necessary and, in the worst case scenario, leaving the group practice in time.

    Background. Acute carbon monoxide poisoning (ACOP) is a significant cause of morbidity and mortality in many countries. Twelve Hand Jing Points (THJP) have been believed to be effective to treat all kinds of emergency calls in traditional Chinese medicine (TCM) for more than 3000 years. This randomized controlled trial (RCT) is designed to evaluate the effectiveness of THJP in curing acute carbon monoxide poisoning in first aid treatment. This paper reports the protocol of the trial. Methods/Design. This RCT is a multicenter, randomized, controlled study undergoing in China. The compliant patients are divided into the bloodletting group and standard of care group. With first aid treatments given to both of the groups, the bloodletting group is bleeding at THJP upon being hospitalized. Primary outcomes and secondary outcomes will be measured and compared between these two groups. Before treatment, immediately after treatment, and 30 minutes, 1 hour, and 4 hours after treatment, patients' basic vital signs and state of consciousness were observed. Before treatment and 1 and 4 hours after treatment, carboxyhemoglobin concentration in venous blood samples was detected. Discussion. The objective of this study is to provide convincing evidence to clarify the efficacy and safety of THJP for early treatment of acute carbon monoxide poisoning. PMID:26339271

    The importance of dental identification is on the increase year after year. With the passage of time, the role of forensic odontology has increased as very often teeth and dental restorations are the only means of identification. Forensic odontology has played a key role in identification of persons in mass disasters (aviation, earthquakes, Tsunamis), in crime investigations, in ethnic studies, and in identification of decomposed and disfigured bodies like that of drowned persons, fire victims, and victims of motor vehicle accidents. The various methods employed in forensic odontology include tooth prints, radiographs, photographic study, rugoscopy, cheiloscopy and molecular methods. Investigative methods applied in forensic odontology are reasonably reliable, yet the shortcomings must be accounted for to make it a more meaningful and relevant procedure. This paper gives an overview of the various experimental studies to aid in the identification processes, discussing their feasibilities and limitations in day-to-day practice. PMID:21731343

    One of Bion's least-acknowledged contributions to psychoanalytic theory is his study of the relationship between the mind of the individual (the ability to think), the mentalities of groups of which the individual is a member, and the individual's bodily states. Bion's early work on group therapy evolved into a study of the interplay between mind and bodily instincts associated with being a member of a group, and became the impetus for his theory of thinking. On the foundation of Bion's ideas concerning this interaction among the thinking of the individual, group mentality, and the psyche-soma, the author presents his thoughts on the ways in which group mentality is recognizable in the analysis of individuals.

    This phenomenological study aimed at understanding, in the light of Martin Buber's philosophy, what is to be a caregiver of children with AIDS. The phenomenological interview guided the meeting with seven caregivers of children with AIDS, selected in a teaching hospital of Porto Alegre-RS, southern of Brazil. The data were interpreted in the light of hermeneutics, emerging the unit of meaning Dialogues 'between' the familiar I and the Eternal THOU. The dialogues take place in the search for answers that allow the understanding of the significance of the impact and challenges they face while living with AIDS. As well, they reveal hope in changes, in the cure and in a vaccine development. We believe that knowing the importance of dialogue in the context of HIV/AIDS epidemic provide the development of a nursing care that brings together the technical-scientific and humanistic aspects.

    either HTLV1 or HTLV2, claiming that ist shape and behavior makes it closer to a group of viruses known as lenti-viruses, so called because they can lie dormant in an animal host for between 5-20 years before becoming active. Prior to the appearance of AIDS, lenti-viruses were hardly ever found in humans. Due to this controversy, the virus has been HTLV3/LAV by the scientific community. What is evident from studies of the disease in Africa, Europe, and the US, is that there are no easy remedies for this highly complex syndrome. Nor is it possible to generalize about it from 1 country to another, let alone 1 continent from another. The way the disease presents itself in Zaire is different from the way it presents itself in Uganda, and both are very different from the way it presents itself in Europe and the US. In Zaire, chronic diarrhea, tuberculosis, pneumonia, and cryptococcal meningitis could all be symptoms of the AIDS patient. AIDS is a recognized public health problem in a number of Central African countries. In those areas where the disease's presence has been confirmed, sexual promiscuity has been singled out as a high risk factor for its transmission. In all affected countries, health authorities are aware of the need to launch health education campaigns. PMID:12314086

    The purpose of this article was to report identified barriers and challenges experienced in the recruiting process of Chinese American adolescents to a cross-sectional HIV/AIDS-related study. Snowball sampling method was used to recruit Chinese American adolescents from Chinese American communities in a U.S. Midwestern state. Barriers and challenges to recruitment were reviewed and analyzed from Chinese cultural perspectives in the hope of aiding researchers and health care providers understand and facilitate future recruitment of Chinese Americans for HIV/AIDS prevention studies. Barriers to recruitment were found related to the taboo topic of sexual issues in Chinese culture, unawareness and denial of HIV/AIDS risks, authoritarian parenting style in Chinese culture, and the required active consents. Facilitating factors of recruiting Chinese American adolescents to future HIV/AIDS prevention research or intervention programs are discussed. Information provided in this article may increase nurses' awareness of various barriers that they might encounter when they conduct research or address HIV/AIDS-related topics of Chinese American adolescents.

    Background Almost 50% of the Nepali health budget is made up of international aid. International Non-Governmental Organizations working in the field of health are able to channel their funds directly to grass root level. During a 2010 conference, the Secretary of Population stated that the government has full knowledge and control over all funds and projects coming to Nepal. However, there are no documents to support this. The study aims to assess government and partner perceptions on whether Government of Nepal currently has full knowledge of contributions of international aid organizations and International Non-Governmental Organizations to health in Nepal and to assess if the government is able to control all foreign contributions to fit the objectives of Second Long Term Health Plan (1997–2017). Methods A qualitative study was performed along with available literature review. Judgmental and snowball sampling led to 26 in depth interviews with key informants from the government, External Development Partners and International Non-Governmental Organizations. Results were triangulated based on source of data. Representatives of the Department of Health Services declined to be interviewed. Data collection was done until researchers felt data saturation had been reached with each group of key informants. Results While Ministry of Health and Population leads the sector wide approach that aims to integrate all donor and International Non-Governmental Organization contributions to health and direct them to the government’s priority areas, questions were raised around its capacity to do so. Similarly, informants questioned the extent to which Social Welfare Council was able to control all International Non-Governmental Organizations contributions.

    2011-10-01

    We propose to observe the neutral hydrogen (HI) content of the spiral-rich NGC 4930 group using the ATCA. This notable group lies 2.5° east of the Centaurus cluster core and is probably infalling for the first time. Our primary goal is to trace the evolutionary changes of spirals in different environments and to map the first signs of interaction and transformation. Our aims of the ATCA observations are (i) to study the HI properties of the group, (ii) to determine if there is an HI deficiency in the members, (iii) to look for any signs of ram pressure stripping that would indicate an interaction with a hot intra-group medium and (iv) to conduct a ‘blind’ survey for new group members, such as dwarf companions within the survey volume. We will further test the latest galaxy finding routines such as Duchamp, which are vital for the success of the upcoming ASKAP HI surveys. The NGC 4930 group is covered in the HI Parkes All Sky Survey but only two out of the nine group members are detected in HI. We propose to make mosaic observations and we expect to detect all of the known galaxies in this group.

    Background Stigma is a key barrier for the delivery of care to patients living with HIV/AIDS (PLWHA). In the Asia region, the HIV/AIDS epidemic has disproportionately affected socially marginalised groups, in particular, injecting drug users. The effect of the stigmatising attitudes towards injecting drug users on perceptions of PLWHA within the health care contexts has not been thoroughly explored, and typically neglected in terms of stigma intervention. Methods Semi-structured interviews were conducted with a group of twenty Thai trainee and qualified nurses. Drawing upon the idea of 'social reciprocity', this paper examines the constructions of injecting drug users and PLWHA by a group of Thai nurses. Narratives were explored with a focus on how participants' views concerning the high-risk behaviour of injecting drug use might influence their attitudes towards PLWHA. Results The analysis shows that active efforts were made by participants to separate their views of patients living with HIV/AIDS from injecting drug users. While the former were depicted as patients worthy of social support and inclusion, the latter were excluded on the basis that they were perceived as irresponsible 'social cheaters' who pose severe social and economic harm to the community. Absent in the narratives were references to wider socio-political and epidemiological factors related to drug use and needle sharing that expose injecting drug users to risk; these behaviours were constructed as individual choices, allowing HIV positive drug users to be blamed for their seropositive status. These attitudes could potentially have indirect negative implications on the nurses' opinions of patients living with HIV/AIDS more generally. Conclusion Decreasing the stigma associated with illicit drugs might play crucial role in improving attitudes towards patients living with HIV/AIDS.

    Aims. The aim of the study was to elicit the safety and efficacy of breast stimulation as an intervention to prevent postdatism and as an aid in spontaneous onset of labour. Methods. Primigravidas with cephalic presentation, without any high-risk factor, were recruited between 36 to 38 weeks of gestation. 200 patients were recruited and randomized into two groups (n = 100). Breast stimulation was advised to one group but not to the other group. Bishop's scoring was done at 38 weeks and repeated at 39 weeks of gestation. Maternal and fetal outcomes were compared in two groups. Result. Bishop's score changed from 3.12 (±1.01) to 3.9 (±1.08) in control group and from 3.02 (±0.82) to 6.08 (±1.29) in breast stimulation group after one week (P value < 0.0001). The period of gestation at delivery was 39.5 (±2.3) weeks in control group and 39.2 (±2.8) weeks in intervention group (P value: 0.044). There were increased chances of vaginal delivery in intervention group (P value: 0.046). Duration of labor, hyperstimulation, presence of meconium stained liquor, postpartum hemorrhage, and neonatal outcomes were similar in both groups. Conclusion. Breast stimulation in low-risk primigravidas helps in cervical ripening and increases chances of vaginal delivery. PMID:25525601

    Researchers planning a longitudinal study typically search, more or less informally, a multivariate space of possible study designs that include dimensions such as the hypothesized true variance in change, indicator reliability, the number and spacing of measurement occasions, total study time, and sample size. The main search goal is to select a research design that best addresses the guiding questions and hypotheses of the planned study while heeding applicable external conditions and constraints, including time, money, feasibility, and ethical considerations. Because longitudinal study selection ultimately requires optimization under constraints, it is amenable to the general operating principles of optimization in computer-aided design. Based on power equivalence theory (MacCallum et al., 2010; von Oertzen, 2010), we propose a computational framework to promote more systematic searches within the study design space. Starting with an initial design, the proposed framework generates a set of alternative models with equal statistical power to detect hypothesized effects, and delineates trade-off relations among relevant parameters, such as total study time and the number of measurement occasions. We present LIFESPAN (Longitudinal Interactive Front End Study Planner), which implements this framework. LIFESPAN boosts the efficiency, breadth, and precision of the search for optimal longitudinal designs. Its initial version, which is freely available at http://www.brandmaier.de/lifespan, is geared toward the power to detect variance in change as specified in a linear latent growth curve model.

    TRIP-aided multi-phase steels were made by thermo-mechanically controlled process, where the ferrite grain size and the amount of the retained austenite were changed by controlling process conditions. The tensile behavior of four steels was studied by in situ neutron diffraction. It is found that the retained austenite bearing about 1.0 wt% C is plastically harder than the ferrite matrix. The steel with a ferrite grain size of {approx}2.0 {mu}m showed tensile strength of 1.1 GPa and a uniform elongation of 18.4%, in which stress-induced martensitic transformation occurs during plastic deformation but a considerable amount of austenite remains even after the onset of necking. It is concluded that the enhancement of uniform elongation is caused mainly by the work-hardening due to the hard austenite and martensite, where the contribution of the transformation strain is negligible.

    The results of the analysis of the external environment of the FBI Fingerprint Identification Division are presented. Possible trends in the future environment of the Division that may have an effect on the work load were projected to determine if future work load will lie within the capability range of the proposed new system, AIDS 3. Two working models of the environment were developed, the internal and external model, and from these scenarios the projection of possible future work load volume and mixture was developed. Possible drivers of work load change were identified and assessed for upper and lower bounds of effects. Data used for the study were derived from historical information, analysis of the current situation and from interviews with various agencies who are users of or stakeholders in the present system.

    User acceptance of new support systems typically was evaluated after the systems were specified, designed, and built. The current study attempts to assess user acceptance of an Automatic-Aided Target Recognition (ATR) system using an emulation of such a proposed system. The detection accuracy and false alarm level of the ATR system were varied systematically, and subjects rated the tactical value of systems exhibiting different performance levels. Both detection accuracy and false alarm level affected the subjects' ratings. The data from two experiments suggest a cut-off point in ATR performance below which the subjects saw little tactical value in the system. An ATR system seems to have obvious tactical value only if it functions at a correct detection rate of 0.7 or better with a false alarm level of 0.167 false alarms per square degree or fewer.

    Objective The longitudinal trajectories that individuals may take from a state of normal cognition to HIV-associated dementia are unknown. We applied a novel statistical methodology to identify trajectories to cognitive impairment, and factors that affected the “closeness” of an individual to one of the canonical trajectories. Design The Multicenter AIDS Cohort Study (MACS) is a four-site longitudinal study of the natural and treated history of HIV Disease among gay and bisexual men. Methods Using data from 3,892 men (both HIV-infected and uninfected) enrolled in the neuropsychology substudy of the MACS, a Mixed Membership Trajectory Model (MMTM) was applied to capture the pathways from normal cognitive function to mild impairment to severe impairment. MMTMs allow the data to identify canonical pathways and to model the effects of risk factors on an individual’s “closeness” to these trajectories. Results We identified three distinct trajectories to cognitive impairment – one “normal aging” (low probability of mild impairment until age 60), one “premature aging” (mild impairment starting at age 45–50), and one “unhealthy” (mild impairment in 20s and 30s) profile. Second, clinically defined AIDS and not simply HIV Disease, was associated with closeness to the premature aging trajectory. And, third, Hepatitis-C infection, Depression, Race, Recruitment Cohort and Confounding Conditions all affected individual’s closeness to these trajectories. Conclusions These results provide new insight into the natural history of cognitive dysfunction in HIV disease and provide evidence for a potential difference in the pathophysiology of the development of cognitive impairment based on trajectories to impairment.

    This study aimed to evaluate the therapeutic effect of traditional Chinese medicine (TCM) by observing the changes in CD4 T-lymphocyte cell count of 110 cases with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) treated continuously with TCM for 84 months. Information of 110 HIV/AIDS patients from 19 provinces and cities treated with TCM from 2004 to 2013 was collected. Changes in the indexes of CD4 counts ( ≤ 200, 201-350, 351-500 and > 500 cells/mm(3)) at five time points (0, 12, 36, 60 and 84 months) and different treatments [TCM and TCM plus antiretroviral therapy (ART)] were compared. Repeated measures test indicated no interaction between group and time (P > 0.05). Degrees of increasing and decreasing CD4 count of the two groups at four different frames were statistically significant compared with the baseline. The CD4 count between the two groups was not statistically significant. For CD4 count of ≤ 200 cells/mm(3), the mean CD4 count changes were 21 and 28 cells/mm(3) per year for the TCM group and TCM plus ART group, respectively. For CD4 count of 201-350 cells/mm(3), the mean CD4 count changes were 6 and 25 cells/mm(3) per year for the TCM group and TCM plus ART group, respectively. For CD4 count of 351-500 cells/mm(3), the mean CD4 count changes were -13 and -7 cells/mm(3) per year for the TCM group and TCM plus ART group, respectively. For CD4 count of > 500 cells/mm(3), the mean CD4 count changes were -34 and -17 cells/mm(3) per year for the TCM group and TCM plus ART group, respectively. Long-term use of TCM could maintain or slow the pace of declining CD4 counts in patients with HIV/AIDS, and may achieve lasting effectiveness. PMID:25190350

    2013-01-01

    Background HIV/AIDS is one of twenty first century’s challenges to human being with protean manifestation affecting nearly all organs of our body. It is causing high morbidity and mortality especially in sub-Saharan Africa with numerous ocular complications and blindness. The purpose of this study was to determine the patterns of ocular manifestations of HIV/AIDS and their correlation with CD4+Tcells count. Methods A cross-sectional study was done on 348 HIV-positive patients presented to Anti-Retroviral Therapy clinics. Data were collected using face-to-face interview, clinical examination and laboratory investigation, and analyzed using SPSS version 13 software. Statistical association test was done and p<0.05 was considered significant. Other statistical tests like student t-test and logistic regression were also done. Results Of 348 patients, 175 were on antiretroviral therapy and 173 were not on therapy. The mean duration of therapy was 27 months. The overall prevalence of ocular manifestations was 25.3%. The commonest ocular manifestation was keratoconjunctivitis sicca (11.3%) followed by blepharitis (3.2%), molluscum contagiosum (2.6%), conjunctival squamous cell carcinoma (2.3%), conjunctival microvasculopathy (2.3%), cranial nerve palsies (2%), herpes zoster ophthalmicus (HZO) (1.2%), and HIV retinopathy (0.6%). HIV retinopathy and conjunctival microvasculopathy were common in patient with CD4+ count of <200 cells/μl while HZO and molluscum contagiosum were common in patients with CD4+ count of 200–499 cells/μl. Prevalence of ocular manifestation was higher among patients on HAART (32.6%) than those patients not on HAART (17.9%) (p<0.05). There was statistically significant association between ocular manifestation and sex, CD4+Tcells count, and age (p<0.05). CD4+ count, <200 cells/μl and age >35 years were independent risk factors for ocular manifestations. Conclusion The study showed that the prevalence of ocular manifestation of HIV/AIDS is

    2012-01-01

    N-Acylhomoserine lactones (AHLs) are used as quorum-sensing (QS) signal molecules by many Gram-negative bacteria. We have reported that Chryseobacterium sp. strain StRB126, which was isolated from the root surface of potato, has AHL-degrading activity. In this study, we cloned and characterized the aidC gene from the genomic library of StRB126. AidC has AHL-degrading activity and shows homology to several metallo-β-lactamase proteins from Bacteroidetes, although not to any known AHL-degrading enzymes. Purified AidC, as a maltose-binding fusion protein, showed high degrading activity against all tested AHLs, whether short- or long-chain forms, with or without substitution at carbon 3. High-performance liquid chromatography (HPLC) analysis revealed that AidC functions as an AHL lactonase catalyzing AHL ring opening by hydrolyzing lactones. An assay to determine the effects of covalent and ionic bonding showed that Zn2+ is important to AidC activity both in vitro and in vivo. In addition, the aidC gene could also be PCR amplified from several other Chryseobacterium strains. In conclusion, this study indicated that the aidC gene, encoding a novel AHL lactonase, may be widespread throughout the genus Chryseobacterium. Our results extend the diversity and known bacterial hosts of AHL-degrading enzymes. PMID:22941089

    PubMed Central

    2010-01-01

    Background This study aimed to develop guidelines for how a member of the Indian public should provide mental health first aid to a person who is suicidal. Methods The guidelines were produced by developing a questionnaire containing possible first aid actions and asking an expert panel of Indian mental health clinicians to rate whether each action should be included in the guidelines. The content of the questionnaire was based on a systematic search of the relevant evidence and claims made by authors of consumer and carer guides and websites. Experts were recruited by SC, EC and HM. The panel members were asked to complete the questionnaire by web survey. Three rounds of the rating were carried and, at the end of each round, items that reached the consensus criterion were selected for inclusion in the guidelines. During the first round, panel members were also asked to suggest any additional actions that were not covered in the original questionnaire (to include items that are relevant to local cultural circumstances, values, and social norms.). Responses to the open-ended questions were used to generate new items. Results The output from the Delphi process was a set of agreed upon action statements. The Delphi process started with 138 statements, 30 new items were written based on suggestions from panel members and, of these 168 items, 71 met the consensus criterion. These statements were used to develop the guidelines appended to this paper. Translated versions of the guidelines will be produced and used for training. Conclusions There are a number of actions that are considered to be useful for members of the public when they encounter someone who is experiencing suicidal thoughts or engaging in suicidal behaviour. Although the guidelines are designed for members of the public, they may also be helpful to non-mental health professionals working in health and welfare settings. PMID:20167125

    Despite recent declines in the rates of cigarette smoking, smoking remains prevalent among individuals with lower income, less education, and those with mental illness or HIV. Exercise is promoted as an aid to smoking cessation; however, the evidence for this recommendation is equivocal. To date, the majority of studies have only examined aerobic exercise; there is a poor understanding of the mechanisms of action; and there is an under-representation of male smokers. The goal of this trial is to produce new data that will help to address each of these gaps. A total of 206 male and female smokers will receive a brief smoking cessation education session prior to being randomized into a 12-week Resistance Training (RT) or Wellness Contact Control group. Both groups will have the option of using nicotine replacement therapy (NRT), and both will meet on-site twice per week during the 12-week program (24 total sessions). Follow-up assessments will occur at the end of the 12-weeks (3-month), and at a 6-month and 12-month (post-randomization) visit. Participants will not receive any additional smoking cessation treatment during follow-up; however, the RT group will receive a 9-month membership to a fitness center to encourage continued resistance training as a way to maintain cessation, and attendance will be tracked. The primary outcome is salivary-cotinine-verified 7-Day Point Prevalence Abstinence (PPA) at the 3-month assessment, and at the 6 and 12-month follow-ups. Secondary outcomes include effects of resistance training on nicotine withdrawal symptoms, indicators of mental health, and markers of disease risk. PMID:25157265

ANOVA test revealed significantly higher mean lead blood concentration in taxi drivers, automechanics, and wood workers compared to other groups. Additionally, workers with lead concentration >0.483 umol/L (10μg/dL) were more likely to have frequent muscle pain compared to those with lower concentrations. No association between other symptoms of lead exposure/toxicity and blood lead concentration was detected. In conclusion, special attention must be directed toward lead blood levels and lead poisoning symptoms when examining patients from certain occupational groups such as taxi drivers, automechanics, and wood workers. Special safety precautions and educational programs are also needed to limit the lead exposure in these occupational groups. PMID:24374433

    Purpose The purpose of this study was to determine whether a belief in the AIDS origin conspiracy theory is related to likelihood or fear of participation in research studies. Methods The Tuskegee Legacy Project Questionnaire was administered via random-digit-dialed telephone interview to black, white, and Hispanic participants in 4 cities in 1999 and 2000 (n = 1,133) and in 3 cities in 2003 (n = 1,162). Results In 1999, 27.8% of blacks, 23.6% of Hispanics, and 8% of whites (P ≤ .001) reported that it was “very or somewhat likely” that AIDS is “the result of a government plan to intentionally kill a certain group of people by genocide.” In 2003, 34.1% of blacks, 21.9% of Hispanics, and 8.4% of whites (P ≤ .001) reported the same. Conclusions Whereas blacks and Hispanics were more than 3 times more likely than whites to believe in this AIDS origin conspiracy theory, holding this belief was not associated with a decreased likelihood of participation in, or increased fear of participation in, biomedical research.

    Background Comparative analysis of expression microarray studies is difficult due to the large influence of technical factors on experimental outcome. Still, the identified differentially expressed genes may hint at the same biological processes. However, manually curated assignment of genes to biological processes, such as pursued by the Gene Ontology (GO) consortium, is incomplete and limited. We hypothesised that automatic association of genes with biological processes through thesaurus-controlled mining of Medline abstracts would be more effective. Therefore, we developed a novel algorithm (LAMA: Literature-Aided Meta-Analysis) to quantify the similarity between transcriptomics studies. We evaluated our algorithm on a large compendium of 102 microarray studies published in the field of muscle development and disease, and compared it to similarity measures based on gene overlap and over-representation of biological processes assigned by GO. Results While the overlap in both genes and overrepresented GO-terms was poor, LAMA retrieved many more biologically meaningful links between studies, with substantially lower influence of technical factors. LAMA correctly grouped muscular dystrophy, regeneration and myositis studies, and linked patient and corresponding mouse model studies. LAMA also retrieves the connecting biological concepts. Among other new discoveries, we associated cullin proteins, a class of ubiquitinylation proteins, with genes down-regulated during muscle regeneration, whereas ubiquitinylation was previously reported to be activated during the inverse process: muscle atrophy. Conclusion Our literature-based association analysis is capable of finding hidden common biological denominators in microarray studies, and circumvents the need for raw data analysis or curated gene annotation databases.

    Auxetic materials (or metamaterials) are those with a negative Poisson ratio (NPR) and display the unexpected property of lateral expansion when stretched, as well as an equal and opposing densification when compressed. Such geometries are being progressively employed in the development of novel products, especially in the fields of intelligent expandable actuators, shape morphing structures and minimally invasive implantable devices. Although several auxetic and potentially auxetic geometries have been summarized in previous reviews and research, precise information regarding relevant properties for design tasks is not always provided. In this study we present a comparative study of two-dimensional and three-dimensional auxetic geometries carried out by means of computer-aided design and engineering tools (from now on CAD-CAE). The first part of the study is focused on the development of a CAD library of auxetics. Once the library is developed we simulate the behavior of the different auxetic geometries and elaborate a systematic comparison, considering relevant properties of these geometries, such as Poisson ratio(s), maximum volume or area reductions attainable and equivalent Young’s modulus, hoping it may provide useful information for future designs of devices based on these interesting structures.

    Background The current study was aimed at understanding the social representation of hearing aids in India, Iran, Portugal, and the United Kingdom. We also compared these results to explore the cross-cultural differences and similarities among these countries. Methods The study involved a cross-sectional design, and the data were collected from four different countries using the snowball sampling method. Data were analyzed using a content analysis to identify the most-similar categories of responses reported, a co-occurrences analysis to see which of these categories are reported commonly, and a chi-square analysis to study if there was any association between positive, neutral, and negative connotations among participants in different countries. Results The current study revealed four different social representations of hearing aids from India, Iran, Portugal, and the United Kingdom, and also a global index. Conclusion The study results provide very useful insights into how hearing aids are represented in the society. These findings may have important implications for public education and also for manufacturers from the viewpoint of designing and marketing hearing aids in different countries. PMID:26504376

    The National Institute of Research and Security and the “CHANTIER Ecole” network have developed first-aid training for employees of integration into the workplace centres. Specifically geared towards workplace safety, but similar in its content to home first-aid and rescue training, this training is also designed to enhance individual and collective responsibility and citizenship. The purpose of this study was to evaluate the personal and interpersonal effects of first-aid training of these employees by considering their social and professional difficulties in terms of psychosocial skills, such as empowerment, stress and emotions management, and decision-making capacity. A descriptive-inductive study was conducted over 18 months based on the grounded theory approach. Five integration into the work-place centres participated in the study and 34 interviews were conducted. These results raise several questions concerning: a) the characteristics of this public targeted by this training and their perception of integration into the workplace; b) the suitability of this training to working conditions and the link with other types of training such as family health education; c) the relationship between citizenship training and first-aid training at work, as it is more applicable to family training than workplace training. A quantitative study is considered to confirm these observations in other integration into the workplace centres. PMID:27392050

    Purpose Adolescents report high asthma-related morbidity that can be prevented by adequate self-management of the disease. Therefore, there is a need for a developmentally appropriate strategy to promote effective asthma self-management. Mobile phone-based technology is portable, commonly accessible, and well received by adolescents. The purpose of this study was to develop and evaluate the feasibility and acceptability of a comprehensive mobile phone-based asthma self-management aid for adolescents (mASMAA) that was designed to facilitate symptom monitoring, treatment adherence, and adolescent–parent partnership. The system used state-of-the-art natural language-understanding technology that allowed teens to use unconstrained English in their texts, and to self-initiate interactions with the system. Materials and methods mASMAA was developed based on an existing natural dialogue system that supports broad coverage of everyday natural conversation in English. Fifteen adolescent–parent dyads participated in a 2-week trial that involved adolescents’ daily scheduled and unscheduled interactions with mASMAA and parents responding to daily reports on adolescents’ asthma condition automatically generated by mASMAA. Subsequently, four focus groups were conducted to systematically obtain user feedback on the system. Frequency data on the daily usage of mASMAA over the 2-week period were tabulated, and content analysis was conducted for focus group interview data. Results Response rates for daily text messages were 81%–97% in adolescents. The average number of self-initiated messages to mASMAA was 19 per adolescent. Symptoms were the most common topic of teen-initiated messages. Participants concurred that use of mASMAA improved awareness of symptoms and triggers, promoted treatment adherence and sense of control, and facilitated adolescent–parent partnerships. Conclusion This study demonstrates the utility and user acceptability of mASMAA as a potential asthma

  3. Perceived Barriers and Facilitators of Using a Web-Based Interactive Decision Aid for Colorectal Cancer Screening in Community Practice Settings: Findings From Focus Groups With Primary Care Clinicians and Medical Office Staff

    PubMed Central

    2013-01-01

    Background Information is lacking about the capacity of those working in community practice settings to utilize health information technology for colorectal cancer screening. Objective To address this gap we asked those working in community practice settings to share their perspectives about how the implementation of a Web-based patient-led decision aid might affect patient-clinician conversations about colorectal cancer screening and the day-to-day clinical workflow. Methods Five focus groups in five community practice settings were conducted with 8 physicians, 1 physician assistant, and 18 clinic staff. Focus groups were organized using a semistructured discussion guide designed to identify factors that mediate and impede the use of a Web-based decision aid intended to clarify patient preferences for colorectal cancer screening and to trigger shared decision making during the clinical encounter. Results All physicians, the physician assistant, and 8 of the 18 clinic staff were active participants in the focus groups. Clinician and staff participants from each setting reported a belief that the Web-based patient-led decision aid could be an informative and educational tool; in all but one setting participants reported a readiness to recommend the tool to patients. The exception related to clinicians from one clinic who described a preference for patients having fewer screening choices, noting that a colonoscopy was the preferred screening modality for patients in their clinic. Perceived barriers to utilizing the Web-based decision aid included patients’ lack of Internet access or low computer literacy, and potential impediments to the clinics’ daily workflow. Expanding patients’ use of an online decision aid that is both easy to access and understand and that is utilized by patients outside of the office visit was described as a potentially efficient means for soliciting patients’ screening preferences. Participants described that a system to link the

    2008-03-01

    Knee-related injuries involving the meniscal or articular cartilage are common and require accurate diagnosis and surgical intervention when appropriate. With proper techniques and experience, confidence in detection of meniscal tears and articular cartilage abnormalities can be quite high. However, for radiologists without musculoskeletal training, diagnosis of such abnormalities can be challenging. In this paper, the potential of improving diagnosis through integration of computer-aided detection (CAD) algorithms for automatic detection of meniscal tears and articular cartilage injuries of the knees is studied. An integrated approach in which the results of algorithms evaluating either meniscal tears or articular cartilage injuries provide feedback to each other is believed to improve the diagnostic accuracy of the individual CAD algorithms due to the known association between abnormalities in these distinct anatomic structures. The correlation between meniscal tears and articular cartilage injuries is exploited to improve the final diagnostic results of the individual algorithms. Preliminary results from the integrated application are encouraging and more comprehensive tests are being planned.

    Acidification is a major constraint for revegetation of sulphidic metal-contaminated soils, as exemplified by the limited literature reporting the successful phytostabilization of mine soils associated with pH<3 and high acidification potential. In this study, a combination of ameliorants (lime and chicken manure) and five acid-tolerant plant species has been employed in order to establish a self-sustaining vegetation cover on an extremely acid (pH<3) polymetallic pyritic mine waste heap in southern China exhibiting high acidification potential. The results from the first two-year data showed that the addition of the amendments and the establishment of a plant cover were effective in preventing soil acidification. Net acid-generating potential of the mine soil decreased steadily, whilst pH and acid neutralization capacity increased over time. All the five acid-tolerant plants colonized successfully in the acidic metal-contaminated soil and developed a good vegetation cover within six months, and subsequent vegetation development enhanced organic matter accumulation and nutrient element status in the mine soil. The two-year remediation program performed on this extremely acid metalliferous soil indicated that aided phytostabilization can be a practical and effective restoration strategy for such extremely acid mine soils.

    A detailed ab initio characterization of the structural, energetic and spectroscopic properties of the novel O4H(+) species is presented. The equilibrium structures and relative energies of all multiplet states have been determined systematically by analyzing static and dynamical correlation effects. The two and three body dissociation processes have been studied and indicate the presence of conical intersections in various states including the ground state. Comparison with available thermochemical data is very good, supporting the applied methodology. The reaction, H3(+) + O4→ O4H(+) + H2, was found to be exothermic ΔH = -19.4 kcal mol(-1) and therefore, it is proposed that the product in the singlet state could be formed in the interstellar medium (ISM) via collision processes. To aid in its laboratory or radioastronomy detection in the interstellar medium we determined spectroscopic fingerprints. It is estimated for the most stable geometry of O4H(+) dipole allowed electronic transitions in the visible region at 429 nm and 666 nm, an intense band at 1745 cm(-1) in the infrared and signals at 40.6, 81.2 and 139.2 GHz in the microwave region at 10, 50 and 150 K respectively, relevant for detection in the ISM.

    Background Decisions about whether to disclose mental health problems to employers are complex, with potential personal, employment and legal implications. Decision aids are evidence based tools, designed to help individuals make specific choices between treatment options. We previously developed a decision aid-Conceal Or ReveAL (CORAL)-to assist service users with decisions about disclosure to employers. As part of a mixed methods exploratory RCT, which demonstrated that the CORAL decision aid was effective in reducing decisional conflict, we aimed to explore its mechanism of action and to optimise the intervention for a future full scale trial. Methods In depth interviews were conducted with individuals receiving vocational support from a mental health trust and participating in the intervention arm of the pilot trial. Thematic analysis was conducted to identify the main themes relating to participants' perceptions of the CORAL decision aid. Results Thirteen participants were interviewed and five main themes were identified: sense of self and values; sense of control; anticipation of disclosure; experience of disclosure; and mechanism of action of the decision aid. Conclusions Data from our 13 participants suggest that the CORAL decision aid acts on several dimensions of decisional conflict: clarifying the pros and cons of different choices; increasing knowledge; structuring the decision making process; and clarifying needs and values. The current study indicated that it would be most effective when delivered by a professional well versed in employment and mental health matters such as a vocational adviser. The need for employers and policymakers to reduce the negative impact of disclosure is also highlighted. PMID:25427673

    Serum antibodies to Giardia lamblia were measured in giardiasis patients, in groups at high risk for intestinal parasite infection, and in controls by an indirect fluorescent antibody (IFA) technique. Symptomatic patients had the highest antibody titers, and antibodies remained present for up to 18 months in persons with chronic infection. Indochinese refugees and male homosexuals with the acquired immunodeficiency syndrome (AIDS) and pre-AIDS had higher mean antibody levels than did healthy controls, whereas sewer and highway maintenance workers had levels similar to those of controls. Serum antibodies to Entamoeba histolytica measured by an indirect hemagglutination antibody technique were detected in only a few Indochinese refugees. We conclude that serology is a promising tool in G. lamblia epidemiology and that further population studies would be of interest. PMID:2886069

    Introduction Emotional Intelligence (EI) is defined as an ability to perceive another’s emotional state combined with an ability to modify one’s own. Physicians with this ability are at a distinct advantage, both in fostering teams and in making sound decisions. Studies have shown that higher physician EI’s are associated with lower incidence of burn-out, longer careers, more positive patient-physician interactions, increased empathy, and improved communication skills. We explored the potential for EI to be learned as a skill (as opposed to being an innate ability) through a brief educational intervention with emergency medicine (EM) residents. Methods This study was conducted at a large urban EM residency program. Residents were randomized to either EI intervention or control groups. The intervention was a two-hour session focused on improving the skill of social perspective taking (SPT), a skill related to social awareness. Due to time limitations, we used a 10-item sample of the Hay 360 Emotional Competence Inventory to measure EI at three time points for the training group: before (pre) and after (post) training, and at six-months post training (follow up); and at two time points for the control group: pre- and follow up. The preliminary analysis was a four-way analysis of variance with one repeated measure: Group x Gender x Program Year over Time. We also completed post-hoc tests. Results Thirty-three EM residents participated in the study (33 of 36, 92%), 19 in the EI intervention group and 14 in the control group. We found a significant interaction effect between Group and Time (p≤0.05). Post-hoc tests revealed a significant increase in EI scores from Time 1 to 3 for the EI intervention group (62.6% to 74.2%), but no statistical change was observed for the controls (66.8% to 66.1%, p=0.77). We observed no main effects involving gender or level of training. Conclusion Our brief EI training showed a delayed but statistically significant positive impact

    This study examined adolescent girls' views of cosmetic surgery. Seven focus groups were run with girls aged 15-18 years (N = 27). Participants read case studies of women having cosmetic surgery, followed by discussion and exploration of their views. Thematic analysis identified four themes: (1) dissatisfaction with appearance, (2) acceptability of cosmetic surgery, (3) feelings about undergoing cosmetic surgery and (4) cosmetic surgery in the media. Results suggest the acceptability of cosmetic surgery varies according to the reasons for having it and that the media play an important role by normalising surgery and under-representing the risks associated with it.

    The principal objectives of the National Facilities Study (NFS) were to: (1) determine where U.S. facilities do not meet national aerospace needs; (2) define new facilities required to make U.S. capabilities 'world class' where such improvements are in the national interest; (3) define where consolidation and phase-out of existing facilities is appropriate; and (4) develop a long-term national plan for world-class facility acquisition and shared usage. The Space Operations Facilities Task Group defined discrete tasks to accomplish the above objectives within the scope of the study. An assessment of national space operations facilities was conducted to determine the nation's capability to meet the requirements of space operations during the next 30 years. The mission model used in the study to define facility requirements is described in Volume 3. Based on this model, the major focus of the Task Group was to identify any substantive overlap or underutilization of space operations facilities and to identify any facility shortfalls that would necessitate facility upgrades or new facilities. The focus of this initial study was directed toward facility recommendations related to consolidations, closures, enhancements, and upgrades considered necessary to efficiently and effectively support the baseline requirements model. Activities related to identifying facility needs or recommendations for enhancing U.S. international competitiveness and achieving world-class capability, where appropriate, were deferred to a subsequent study phase.

    This technical note describes some Bayesian procedures for the analysis of group studies that use nonlinear models at the first (within-subject) level - e.g., dynamic causal models - and linear models at subsequent (between-subject) levels. Its focus is on using Bayesian model reduction to finesse the inversion of multiple models of a single dataset or a single (hierarchical or empirical Bayes) model of multiple datasets. These applications of Bayesian model reduction allow one to consider parametric random effects and make inferences about group effects very efficiently (in a few seconds). We provide the relatively straightforward theoretical background to these procedures and illustrate their application using a worked example. This example uses a simulated mismatch negativity study of schizophrenia. We illustrate the robustness of Bayesian model reduction to violations of the (commonly used) Laplace assumption in dynamic causal modelling and show how its recursive application can facilitate both classical and Bayesian inference about group differences. Finally, we consider the application of these empirical Bayesian procedures to classification and prediction. PMID:26569570

    Psychometric properties of external HIV-related stigma and discrimination scales and their predictors were investigated. A cross-sectional community-based study was carried out among 520 participants using an ongoing health and demographic surveillance system in León, Nicaragua. Participants completed an 18-item HIV stigma scale and 19 HIV and AIDS discrimination-related statements. A factor analysis found that 15 of the 18 items in the stigma scale and 18 of the 19 items in the discrimination scale loaded clearly into five- and four-factor structures, respectively. Overall Cronbach's alpha of .81 for the HIV stigma scale and .91 for the HIV discrimination scale provided evidence of internal consistency. Hierarchical multiple linear regression analysis identified that females, rural residents, people with insufficient HIV-related transmission knowledge, those not tested for HIV, those reporting an elevated self-perception of HIV risk, and those unwilling to disclose their HIV status were associated with higher stigmatizing attitudes and higher discriminatory actions towards HIV-positive people. This is the first community-based study in Nicaragua that demonstrates that overall HIV stigma and discrimination scales were reliable and valid in a community-based sample comprised of men and women of reproductive age. Stigma and discrimination were reported high in the general population, especially among sub-groups. The findings in the current study suggest community-based strategies, including the monitoring of stigma and discrimination, and designing and implementing stigma reduction interventions, are greatly needed to reduce inequities and increase acceptance of persons with HIV.

    Background Ethnic minority groups are under-represented in mental health care services because of barriers such as poor mental health literacy. In 2007, the Mental Health First Aid (MHFA) program implemented a cultural adaptation of its first aid course to improve the capacity of Indigenous Australians to recognise and respond to mental health issues within their own communities. It became apparent that the content of this training would be improved by the development of best practice guidelines. This research aimed to develop culturally appropriate guidelines for providing first aid to an Australian Aboriginal or Torres Strait Islander person who is experiencing a mental health crisis or developing a mental illness. Methods A panel of Australian Aboriginal people who are experts in Aboriginal mental health, participated in six independent Delphi studies investigating depression, psychosis, suicidal thoughts and behaviours, deliberate self-injury, trauma and loss, and cultural considerations. The panel varied in size across the studies, from 20-24 participants. Panellists were presented with statements about possible first aid actions via online questionnaires and were encouraged to suggest additional actions not covered by the survey content. Statements were accepted for inclusion in a guideline if they were endorsed by ≥ 90% of panellists as essential or important. Each study developed one guideline from the outcomes of three Delphi questionnaire rounds. At the end of the six Delphi studies, participants were asked to give feedback on the value of the project and their participation experience. Results From a total of 1,016 statements shown to the panel of experts, 536 statements were endorsed (94 for depression, 151 for psychosis, 52 for suicidal thoughts and behaviours, 53 for deliberate self-injury, 155 for trauma and loss, and 31 for cultural considerations). The methodology and the guidelines themselves were found to be useful and appropriate by the

    The Undergraduate ALFALFA (Arecibo Legacy Fast ALFA) Team Groups Project is a collaborative undertaking of faculty and students at 11 institutions, aimed at investigating properties of galaxy groups surveyed by the ALFALFA blind HI survey. The survey covers 7,000 square degrees and is expected to include more than 30,000 extragalactic sources when completed. Here we present analysis of HI spectra taken at the National Astronomy and Ionosphere Center and report on progress made with developing analysis software tools as part of the UAT study. These tools will be implemented with follow up observations of targeted sources generated from the original blind survey. This work has been supported by NSF grants AST-0724918, AST-0725267 and AST-0725380.

    PubMed

    Schieman, S

    1998-06-01

    Over the past decade, researchers have accumulated evidence that suggests six main factors are associated with AIDS-related risk reduction behavior: (a) perceived susceptibility (Dolcini et al., 1995; van der Plight & Richard, 1994); (b) attitudes toward condoms (Catania et al., 1994; Maticka-Tynadale, 1991); (c) personally knowing someone with HIV/AIDS (Joseph et al., 1987); (d) perceived peer norms about risk-reduction (Maticka-Tyndale, 1991); (e) previous sexual activity (Joseph et al., 1987); and (f) self-efficacy (Aspinwall, Kemeny, Taylor, & Schneider, 1991; van der Plight & Richard, 1994). Furthermore, there is some suggestion that the epidemiology and sociocultural constructions of the disease has led to considerable gender, racial, and class differences in awareness of AIDS, perception of HIV threat, and HIV-relevant behavior (Cohan & Atwood, 1994; Dolcini et al., 1995; Gillies, 1994).

    The lentivirus feline immunodeficiency virus (FIV) is a widespread pathogen of the domestic cat that is mainly transmitted through bites, although other means of transmission are also possible. Its prevalence ranges from 1 to 10% in different cat populations throughout the world, thus representing a large reservoir of naturally infected animals. FIV resembles the human immunodeficiency virus (HIV) in many respects. Similarities include the structural features of the virion, the general organization and great variability of the genome, the life cycle in the infected host, and most importantly, the pathogenic potential. Infection is associated with laboratory signs of immunosuppression as well as with a large variety of superinfections, tumors, and neurological manifestations. Our understanding of FIV is steadily improving and is providing important clues to the pathogenesis of immunodeficiency-inducing lentiviruses. The cellular receptor for FIV is different from the feline equivalent of the human CD4 molecule used by HIV; nevertheless, the major hallmark of infection is a progressive loss of CD4+ T lymphocytes as in HIV infection. The mechanisms by which FIV escapes the host's immune responses are being actively investigated. FIV causes lysis of infected T cells and also appears to predispose these cells to apoptosis. Infection of macrophages and other cell types has also been documented. For reasons yet to be understood, antibody-mediated neutralization of fresh FIV isolates is very inefficient both in vitro and in vivo. Vaccination studies have provided some encouraging results, but the difficulties encountered appear to match those met in HIV vaccine development. FIV susceptibility to antiviral agents is similar to that of HIV, thus providing a valuable system for in vivo preclinical evaluation of therapies. It is concluded that in many respects FIV is an ideal model for AIDS studies. PMID:7704896

    When recently polled, one half of 4,100 physicians believed they had the right not to treat patients with the acquired immunodeficiency syndrome (AIDS), and 15% said they would actually refuse to care for them. To assure medical care for the 365,000 AIDS patients projected for the US by 1992, it is imperative to know whether there is something unique about AIDS patients that produces aversion among physicians. We hypothesized that the desire to avoid AIDS patients derived from three fears: fear of contagion, homophobia, and a desire to avoid dying patients. To identify the extent to which these three fears affect the attitudes that students hold toward AIDS patients, we conducted three studies. In our first study, we discovered that students' views about a patient with a terminal illness are the same whether the illness is leukemia or AIDS. In the second study, we found that the patient's sexual preference was not the major reason students would avoid an AIDS patients. In a third study, we confirmed that fear of contagion is the principal cause of students' desire to avoid an AIDS patient. In the course of these studies, we found important differences between the attitudes of male and female students. Female students scored lower on the homophobic scale than male students, and they had less antipathy toward AIDS patients. Helping health care professionals understand their fears toward patients with AIDS will in the long run improve medical care. Since the origins of these fears are for the most part well hidden in our unconscious, dissemination of facts alone will not do the job. Interventions are needed to help health care professionals acknowledge and overcome their negative feelings about AIDS. PMID:2705068

    AIDS video education is a major mode of providing information about the spread and prevention of the human immunodeficiency virus (HIV). Very little has been written about the need for culturally salient messages in increasing the acquisition and retention of HIV/AIDS prevention information, even though there is considerable agreement that limited culturally sensitive information is reaching African-American youth. This investigation sought to ascertain the impact of a culturally similar AIDS video on the acquisition of AIDS knowledge and endorsement of HIV/AIDS prevention beliefs. This study randomly assigned classes of African-American teenagers to one of two treatment groups: culturally similar video (CSV) AIDS education and culturally dissimilar video (CDV) AIDS education. Results suggest that the CSV group demonstrated significant improvement in pre- to post- AIDS knowledge scores compared to the CDV group (using ANCOVA procedures). The intervention was not significant in demonstrating change in beliefs about prevention. Implications for the development of HIV/AIDS prevention programs for inner-city African-American youth are discussed. PMID:8024942

    Background Confrontation with a life-threatening disease like cancer can evoke existential distress, which can trigger a search for meaning in people after having survived this disease. Methods In an effort to gain more insight in the meaning making process, we conducted four focus groups with 23 cancer survivors on this topic. Participants responded to questions about experienced meaning making, perceived changes in meaning making after cancer and the perceived need for help in this area. Results Most frequently mentioned meaning making themes were relationships and experiences. We found that, in general, cancer survivors experienced enhanced meaning after cancer through relationships, experiences, resilience, goal-orientation and leaving a legacy. Some participants, however, also said to have (also) experienced a loss of meaning in their lives through experiences, social roles, relationships and uncertainties about the future. Conclusions The results indicated that there is a group of cancer survivors that has succeeded in meaning making efforts, and experienced sometimes even more meaning in life than before diagnosis, while there is also a considerable group of survivors that struggled with meaning making and has an unmet need for help with that. The results of this study contribute to develop a meaning centered intervention for cancer survivors. PMID:24086695

    Current literature on aid effectiveness describes increasing use of a more contractual approach to the relationship between donor and recipient government in which a system of rewards and penalties for good and bad performance operates. The purpose of this case study of the Ugandan health sector was to understand the extent to which this approach is influencing processes and effectiveness. This qualitative study used a conceptual framework based on agency theory and 'realistic evaluation'. Our results showed that the main official mechanism to assess and reward performance established through the Sector Wide Approach lacked objective criteria and was based on an unstructured system of discussions and agreements among donors. The achievement of a satisfactory performance rating was facilitated by the agreeing to undertakings that were under-demanding, vaguely formulated and lacking quantitative benchmarks against which progress could be measured. However, even when poor performance was readily observable, penalties failed to be applied by donors. This was always the case in relation to health sector performance and mostly so in relation to general governance and accountability. Funds continued to be disbursed despite the lack of progress made in achieving targets and undertakings and other evident performance problems (e.g. in the area of governance). A series of explanations of the failure to penalise were put forward by donor representatives in relation to this behaviour including the need to maintain long-term relationships based on trust and not to undermine health sector performance by withdrawing aid. Thus there are likely to be incentives to disburse funds and report success, irrespective of the realities of aid programmes in the context of large foreign aid volumes associated with increased political visibility of aid in donor countries.

    The National AIDS Convention in South Africa (NACOSA) in October 1992 was the first real attempt to address HIV/AIDS. In Soweto, government, the African National Congress, nongovernmental organizations, and organized industry and labor representatives worked for 2 days to develop a national plan of action, but it did not result in a united effort to fight AIDS. The highest HIV infection rates in South Africa are among the KwaZulu in Natal, yet the Inkatha Freedom Party did not attend NACOSA. This episode exemplifies the key obstacles for South Africa to prevent and control AIDS. Inequality of access to health care may explain why health workers did not diagnose the first AIDS case in blacks until 1985. Migrant labor, Bantu education, and uprooted communities affect the epidemiology of HIV infection. Further, political and social polarization between blacks and whites contributes to a mindset that AIDS is limited to the other race which only diminishes the personal and collective sense of susceptibility and the volition and aptitude to act. The Department of National Health and Population Development's voluntary register of anonymously reported cases of AIDS specifies 1517 cumulative AIDS cases (October 1992), but this number is low. Seroprevalence studies show between 400,000-450,000 HIV positive cases. Public hospitals cannot give AIDS patients AZT and DDI. Few communities provided community-based care. Not all hospitals honor confidentiality and patients' need for autonomy. Even though HIV testing is not mandatory, it is required sometimes, e.g., HIV testing of immigrants. AIDS Training, Information and Counselling Centers are in urban areas, but not in poor areas where the need is most acute. The government just recently developed in AIDS education package for schools, but too many people consider it improper, so it is not being used. The poor quality education provided blacks would make it useless anyhow. Lifting of the academic boycott will allow South African

    GHB (gamma hydroxybutyrate) is a significant new drug of abuse added to the United States Controlled Substance Act in 2000. The majority of the published literature on GHB consists of clinical case reports, mainly from emergency departments, and a collection of laboratory-based studies, focused mainly on anesthesia. While comments about the various experiences and behaviors of human users are often included in such studies or reports, these aspects of GHB are only just beginning to be systematically investigated or detailed. Reported here are data from a qualitative study using focus group methods on the consumption habits, experiences, and beliefs of GHB users. A total of 51 people, 30 men and 21 women, mean age of 31.1±7.6 years (range 18 – 52 years), who report having used GHB for an average of 4.3±2.5 years (range 1–11 years), were interviewed in 10 separate groups held in 2004. This paper discusses broadly the general experience of the GHB ‘high,’ major perceived benefits including sexual responses to the drug, perceived risks and dangers of ingestion, co-ingestion, and various contexts of use. The paper concludes with a discussion of the implications drawn from this information for clinicians treating patients who use GHB. PMID:17703706

    We study the quantum phase transition (QPT) induced by dissipation in a quantum dot device at the degeneracy point. We employ a Bose-Fermi numerical renormalization group approach [1] to study the simplest case of a spinless resonant-level model that couples the charge density on the dot to a dissipative bosonic bath with density of states B(φ)ŝ. In anticipation of future experiments [2] and to assess further the validity of theoretical techniques in this rapidly developing area, we take the conduction-electron leads to have a pseudogap density of states: ρ(φ) |φ|^r, as considered in a very recent perturbative renormalization group study [3]. We establish the conditions on r and s such that a QPT arises with increasing dissipation strength --- from a delocalized phase, where resonant tunneling leads to large charge fluctuations on the dot, to a localized phase where such fluctuations are frozen. We present results for the single-particle spectrum and the response of the system to a local electric field, extracting critical exponents that depend in general on r and s and obey hyperscaling relations. We make full comparison with results of [3] where appropriate. Supported by NSF Grant DMR-0312939. [1] M. T. Glossop and K. Ingersent, PRL 95, 067202 (2005); PRB (2006). [2] L. G. G. V.

    It is well known that the liver is an organ easily attacked by diseases. The purpose of this study is to develop a computer-aided diagnosis (CAD) scheme for helping radiologists to differentiate hepatic diseases more efficiently. Our software named LIVERANN integrated the magnetic resonance (MR) imaging findings with different pulse sequences to classify the five categories of hepatic diseases by using the artificial neural network (ANN) method. The intensity and homogeneity within the region of interest (ROI) delineated by a radiologist were automatically calculated to obtain numerical data by the program for input signals to the ANN. Outputs were the five pathological categories of hepatic diseases (hepatic cyst, hepatocellular carcinoma, dysplasia in cirrhosis, cavernous hemangioma, and metastasis). The experiment demonstrated a testing accuracy of 93% from 80 patients. In order to differentiate the cirrhosis from normal liver, the volume ratio of left to whole (LTW) was proposed to quantify the degree of cirrhosis by three-dimensional (3D) volume analysis. The liver region was firstly extracted from computed tomography (CT) or MR slices based on edge detection algorithms, and then separated into left lobe and right lobe by the hepatic umbilical fissure. The volume ratio of these two parts showed that the LTW ratio in the liver was significantly improved in the differentiation performance, with (25.6%{+-}4.3%) in cirrhosis versus the normal liver (16.4%{+-}5.4%). In addition, the application of the ANN method for detecting clustered microcalcifications in masses on mammograms was described here as well. A new structural ANN, so-called a shift-invariant artificial neural network (SIANN), was integrated with our triple-ring filter (TRF) method in our CAD system. As the result, the sensitivity of detecting clusters was improved from 90% by our previous TRF method to 95% by using both SIANN and TRF.

    Background Computer-aided diagnosis (CADx) software that provides a second opinion has been widely used to assist physicians with various tasks. In dermatology, however, CADx has been mostly limited to melanoma or melanocytic skin cancer diagnosis. The frequency of non-melanocytic skin cancers and the accessibility of regular digital macrographs have raised interest in developing CADx for broader applications. Objectives To investigate the feasibility of using CADx to diagnose both melanocytic and non-melanocytic skin lesions based on conventional digital photographic images. Methods This study was approved by an institutional review board, and the requirement to obtain informed consent was waived. In total, 769 conventional photographs of melanocytic and non-melanocytic skin lesions were retrospectively reviewed and used to develop a CADx system. Conventional and new color-related image features were developed to classify the lesions as benign or malignant using support vector machines (SVMs). The performance of CADx was compared with that of dermatologists. Results The clinicians' overall sensitivity, specificity, and accuracy were 83.33%, 85.88%, and 85.31%, respectively. New color correlation and principal component analysis (PCA) features improved the classification ability of the baseline CADx (p = 0.001). The estimated area under the receiver operating characteristic (ROC) curve (Az) of the proposed CADx system was 0.949, with a sensitivity and specificity of 85.63% and 87.65%, respectively, and a maximum accuracy of 90.64%. Conclusions We have developed an effective CADx system to classify both melanocytic and non-melanocytic skin lesions using conventional digital macrographs. The system's performance was similar to that of dermatologists at our institute. Through improved feature extraction and SVM analysis, we found that conventional digital macrographs were feasible for providing useful information for CADx applications. The new color

    Persons living with AIDS are highly vulnerable to foodborne enteric infections including recurrent Salmonella septicemia and toxoplasmosis of the brain with the potential for substantial morbidity and mortality. Patients with immunologic AIDS in Chicago, New Orleans, and Bayamon were interviewed to determine gaps in food safety knowledge and prevalence of related behaviors in order to create targeted educational material for this population. A food safety score was calculated based on responses to 40 knowledge, belief, and behavior questions. Among 268 AIDS patients interviewed, the overall food safety score was 63% (range 28% to 93%). Many patients believed it was okay to eat higher risk food (38% for eating eggs served loose or runny, 27% for eating store-bought hot dogs without heating them first), 40% did not know that eating unpasteurized cheese may get germs inside their body that could cause hospitalization and possibly death, and 40% would not throw away salad that had been splashed with a few drops of raw chicken juice. These data demonstrate substantial knowledge gaps and behavioral risk related to acquisition of foodborne disease among AIDS patients. Healthcare providers should incorporate education regarding foodborne disease risk into routine outpatient discussion of improving and maintaining their health. PMID:25061438

    In Vietnam, discrimination against people living with HIV/AIDS (PLHIV) is defined within and prohibited by the 2007 national HIV/AIDS law. Despite the law, PLHIV face discrimination in health care, employment, education and other spheres. This study presents the first national estimates of the levels and types of discrimination that are defined in Vietnamese law and experienced by PLHIV in Vietnam. A nationally representative sample of 1200 PLHIV was surveyed, and 129 PLHIV participated in focus group discussions (FGDs). In the last 12 months, nearly half of the survey population experienced at least one form of discrimination and many experienced up to six different types of discrimination. The most common forms of discrimination included disclosure of HIV status without consent; denial of access to education for children; loss of employment; advice, primarily from health care providers, to abstain from sex; and physical and emotional harm. In logistic regression analysis, the experience of discrimination differed by gender, region of residence and membership status in a PLHIV support group. The logistic regression and FGD results indicate that disclosure of HIV status without consent was associated with experiencing other forms of discrimination. Key programme and policy recommendations are discussed. PMID:22974225

  2. Best practice workplace HIV/AIDS programmes in South Africa: A review of case studies and lessons learned

    2009-01-01

    ABSTRACT Background A group of experts attending a tripartite interregional meeting on best practices in HIV/AIDS workplace policies and programmes organised by the International Labour Organisation (ILO) in Geneva, Switzerland, identified 34 best practice workplace HIV programmes from across the world. Method The ten criteria that were used for reviewing best practice workplace HIV/AIDS programmes in South Africa include acceptability, accessibility, ethical soundness, perceived impact, relevance, appropriateness, innovativeness, efficiency, sustainability and replicability. Results More than one-third (35.3%) of the 34 best practice workplace interventions identified were found in businesses and industries in South Africa. This constitutes a significant and encouraging effort to deal with HIV/AIDS in the workplace. Approximately 16.7% of the best practice workplace HIV/AIDS interventions focused on policy and legal frameworks, 50% of these interventions focused on prevention, 16.7% provided links beyond the workplace and a further 16.7% were interventions that focused on knowledge and evidence. A third (33.3%) of practices were found in the mining industry, 16.7% in the motor industry, 16.7% from workers’ unions, and the rest (33.3%) were found in a sugar company, an electricity supply company, a pharmaceutical company and the ministry of Public Service and Administration. Conclusion It is encouraging that over one-third of all best practice workplace HIV interventions identified by the ILO experts were found in South Africa. The majority of these policies and programmes were focused on HIV prevention.

    The first people to be infected with HIV in Malaysia were mainly homosexual men with foreign connections. IV drug users, however, rapidly became the population group with the highest prevalence of HIV. Accurate, timely data are needed in order to responsibly describe the pattern of HIV infection and AIDS in any given setting. In Malaysia, however, there has been little systematic surveillance in population groups other than blood donors. This surveillance indicates the existence of a rapidly increasing rate of seropositivity among blood donors. Otherwise, many people are loathe to undergo voluntary HIV testing to determine their serostatus. Moreover, some people with STDs avoid contact with the health system and the potential for HIV testing. The extent to which AIDS cases are underreported or reported late is unknown. On the other hand, an estimated 10% of notified AIDS cases have been wrongly classified as such. The lack of hard data on HIV/AIDS in Malaysia makes it difficult to project the future course of the epidemic in the country. Since Malaysia shares a land border with Thailand and there is much sea-borne traffic between the two countries, it is highly possible that Malaysia will experience a significant epidemic of HIV infection similar to its neighbors. A National AIDS Committee was established April 1985 to develop responses to the HIV epidemic, while the National AIDS Program Manager of the Ministry of Health is responsible for controlling STDs. A national plan of action for the prevention and control of AIDS, drawn up in 1985 and revised in 1988, includes planning for the continued surveillance of HIV infection and AIDS through existing notification systems, and for screening and sentinel programs for IV drug users, prostitutes, and STD patients. Recent nongovernmental organization responses complement government efforts to prevent HIV and AIDS in Malaysia. PMID:7857575

    Background. Evidence-based clinical guidelines could support shared decision-making and help patients to participate actively in their care. However, it is not well known how patients view guidelines as a source of health information. This qualitative study aimed to assess what patients know about guidelines, and what they think of their presentation formats. Research question. What is the role of guidelines as health information for patients and how could the implementation of evidence-based information for patients be improved? Methods. A qualitative study with focus groups that were built around a semi-structured topic guide. Focus groups were audiotaped and transcribed and analysed using a phenomenographic approach. Results. Five focus groups were carried out in 2012 with a total of 23 participants. Patients searched for health information from the Internet or consulted health professionals or their personal networks. The concepts of guidelines included instructions or standards for health professionals, information given by a health professional to the patient, and material to protect and promote the interests of patients. Some patients did not have a concept for guidelines. Patients felt that health information was abundant and its quality sometimes difficult to assess. They respected conciseness, clarity, clear structure, and specialists or well-known organizations as authors of health information. Patients would like health professionals to deliver and clarify written materials to them or point out to them the relevant Internet sites. Conclusions. The concept of guidelines was not well known among our interviewees; however, they expressed an interest in having more communication on health information, both written information and clarifications with their health professionals.

    Young people are of particular importance in state policies against AIDS. The present study investigated the attitude toward HIV/AIDS and related socio-cultural factors among 600 high school students in Shiraz, Iran. The method of sampling is a stratified one and the instrument for collecting data is a self-administrated questionnaire. In this research, attitude has three dimensions-knowledge, emotion and tendency to action. Descriptive statistics showed that students did not have enough knowledge about HIV/AIDS. The 44.3% of students had low knowledge, 36.9% moderate knowledge and only 18.8% had high knowledge. Also the results indicated that attitude for 69.8% of student has in middle level, 15.4% positive and 14.9% negative. Moreover, results suggested that loyalty to Islamic religious beliefs have an important role on attitude toward this disease. Major of study, sex, mother's occupation and use of some mass media such as books and newspapers were other main influencing factors in the students' attitude. Furthermore, this study showed that parent education, major of study, father's occupation and use of books and the Internet are the most important variables affecting on the participants' knowledge. Age, sex, parents' education, religious beliefs, use of some mass media such as TV, the internet, newspapers, satellite and books affect emotion. Finally, there is a relationship between religious beliefs, sex and major of study, use of satellite, television, radio and books with tendency to action. PMID:20506714

    Objectives One of the goals of the medical master’s degree is for a student to become a gender-sensitive doctor by applying knowledge of gender differences in practice. This study aims to investigate, from the students’ perspective, whether gender medicine has been taught in daily practice during clerkship. Methods A focus group study was conducted among 29 medical students from Radboud University, Nijmegen, The Netherlands, who had just finished either their internal medicine or surgical clerkships. Data were analyzed in line with the principles of constant comparative analysis. Results Four focus groups were conducted with 29 participating students. Clinical teachers barely discuss gender differences during students’ clerkships. The students mentioned three main explanatory themes: insufficient knowledge; unawareness; and minor impact. As a result, students feel that they have insufficient competencies to become gender-sensitive doctors. Conclusion Medical students at our institution perceive that they have received limited exposure to gender-based education after completing two key clinical clerkships. All students feel that they have insufficient knowledge to become gender-sensitive doctors. They suppose that their clinical teachers have insufficient knowledge regarding gender sensitivity, are unaware of gender differences, and the students had the impression that gender is not regarded as an important issue. We suggest that the medical faculty should encourage clinical teachers to improve their knowledge and awareness of gender issues. PMID:24600301

    Background Coronary artery disease (CAD) has been associated with HIV infection; however data are not consistent. Objective We performed cardiac CT to determine whether HIV-infected men have more coronary atherosclerosis than uninfected men. Design Cross-sectional study within the Multicenter AIDS Cohort Study(MACS). Participants HIV-infected (n=618) and –uninfected (n=383) men who have sex with men (MSM) had non-contrast and contrast enhanced cardiac CT if they were between 40–70 years, weighed <300 pounds, and had no history of coronary revascularization. Measurements Presence and extent, for those with plaque, of coronary artery calcium (CAC) on non-contrast CT, and of any plaque, non-calcified, mixed or calcified plaque and stenosis on CT angiography. Results 1001 men underwent non-contrast CT of whom 759 had coronary CT angiography. After adjusting for age, race, center, and cohort, HIV-infected men had a greater prevalence of CAC [Prevalence ratio(PR)=1.21, 95% confidence interval (CI) 1.08–1.35, p=0.001], and any plaque [PR=1.14(1.05–1.24),p=0.001], including non-calcified plaque [PR=1.28(1.13–1.45),p<0.001) and mixed plaque [PR=1.35(1.10–1.65),p=0.004] than HIV-uninfected men. Associations between HIV-infection and any plaque and non-calcified plaque remained significant (p<0.005) after CAD risk factor adjustment. HIV-infected men also had a greater extent of non-calcified plaque after CAD risk factor adjustment (p=0.026). HIV-infected men had a greater prevalence of coronary artery stenosis>50% than HIV-uninfected men [PR=1.48(1.06–2.07),p=0.020), but not after CAD risk factor adjustment. Longer duration of highly active antiretroviral therapy [PR=1.09(1.02–1.17), p=0.007,per year] and lower nadir CD4+ T-cell count [PR=0.80(0.69–0.94),p=0.005, per 100 cells] were associated with coronary stenosis>50%. Conclusions Coronary artery plaque, especially non-calcified plaque, is more prevalent and extensive in HIV-infected men, independent of

    (See the Editorial Commentary by Nachman, on pages 1035–6.) Background. Highly active antiretroviral therapy (HAART) has improved human immunodeficiency virus (HIV)–associated morbidity and mortality. The bimodal mortality distribution in HIV-infected children makes it important to evaluate temporal effects of HAART among a birth cohort with long-term, prospective follow-up. Methods. Perinatal AIDS Collaborative Transmission Study (PACTS)/PACTS–HIV Follow-up of Perinatally Exposed Children (HOPE) study was a Centers for Disease Control and Prevention–sponsored multicenter, prospective birth cohort study of HIV-exposed uninfected and infected infants from 1985 until 2004. Mortality was evaluated for the no/monotherapy, mono-/dual-therapy, and HAART eras, that is, 1 January 1986 through 31 December 1990, from 1 January 1991 through 31 December 1996, and 1 January 1997 through 31 December 2004. Results. Among 364 HIV-infected children, 56% were female and 69% black non-Hispanic. Of 98 deaths, 79 (81%) and 61 (62%) occurred in children ≤3 and ≤2 years old, respectively. The median age at death increased significantly across the eras (P < .0001). The average annual mortality rates were 18 (95% confidence interval [CI], 11.6–26.8), 6.9 (95% CI, 5.4–8.8), and 0.8 (95% CI, 0.4–1.5) events per 100 person-years for the no/monotherapy, mono-/dual-therapy and HAART eras, respectively. The corresponding 6-year survival rates for children born in these eras were 57%, 76%, and 91%, respectively (P < .0001). Among children who received HAART in the first 6 months of age, the probability of 6-year survival was 94%. Ten-year survival rates for HAART and non-HAART recipients were 94% and 45% (P < .05). HAART-associated reductions in mortality remained significant after adjustment for confounders (hazard ratio, 0.3; 95% CI, .08–.76). Opportunistic infections (OIs) caused 31.8%, 16.9%, and 9.1% of deaths across the respective eras (P = .051). Conclusions

    Introduction Sex determination in forensic anthropology is an essential step for medico-legal purposes and crucial for identification as the number of possible matches is reduced to 50%. Teeth are an excellent material for anthropological, genetic, odontological and forensic investigations as they are known to resist a variety of ante-mortem and post-mortem insults. Sexual dimorphism in tooth size and the accuracy of odontometric sex prediction is found to vary in different population and therefore it is necessary to determine specific population values in order to make identification possible. Hence, the present study was undertaken to evaluate the existence of sexual dimorphism in South Kerala population. Aim To evaluate and estimate the degree of odontometric sexual dimorphism in all permanent teeth except third molars and the variations in odontometric dimensions between the left and right side teeth of the maxillary and mandibular arches in male and female groups. Materials and Methods The MesioDistal (MD) and BuccoLingual (BL) measurements of 28 teeth were estimated from the preorthodontic casts of 132 subjects; male group (66 males) and female group (66 females) of age range 15-25 years using digital Verniers’ Caliper. The data obtained were analysed using SPSS version 17 and the Students’ t-test for two independent samples. Results The MesioDistal (MD) and BuccoLingual (BL) parameters of all permanent teeth in the study group showed sexual dimorphism. Over 39% of the tooth variables showed reverse dimorphism. The comparison of mean values of MD and BL diameters of the maxillary and mandibular, right and left side teeth in male and female groups showed statistical significance in males whereas females show non-significant values in both MD and BL diameters. Conclusion The study showed a varied percentage of sexual dimorphism and variation in the mean values of MD and BL dimensions in males, but not in females between right and left side teeth of the

    The Tuskegee study of untreated syphilis in the Negro male is the longest nontherapeutic experiment on human beings in medical history. The strategies used to recruit and retain participants were quite similar to those being advocated for HIV/AIDS prevention programs today. Almost 60 years after the study began, there remains a trail of distrust and suspicion that hampers HIV education efforts in Black communities. The AIDS epidemic has exposed the Tuskegee study as a historical marker for the legitimate discontent of Blacks with the public health system. The belief that AIDS is a form of genocide is rooted in a social context in which Black Americans, faced with persistent inequality, believe in conspiracy theories about Whites against Blacks. These theories range from the belief that the government promotes drug abuse in Black communities to the belief that HIV is a manmade weapon of racial warfare. An open and honest discussion of the Tuskegee Syphilis Study can facilitate the process of rebuilding trust between the Black community and public health authorities. This dialogue can contribute to the development of HIV education programs that are scientifically sound, culturally sensitive, and ethnically acceptable. PMID:1951814

    This paper reports on an aspect of a larger ethnographic study that sought to investigate the impact of HIV/AIDS on the practice of primary care nurses in Jordan. Nursing leadership and the style of management adopted by senior nursing and medical administrators at the Ministry of Heath were identified as factors impacting on the practice of the nurses and their capacity to raise community awareness and contribute to the prevention and control of HIV/AIDS. The study was undertaken in three rural and three urban primary health care centres (PHCC). Data collection included participant observation, key informant interviews, and document analysis. These data informed the development of descriptive ethnographic accounts that allowed for the subsequent identification of common and divergent themes reflective of factors recognized as influencing the practice of the nurse participants.

    Censored data are characteristics of many bioassays in HIV/AIDS studies where assays may not be sensitive enough to determine gradations in viral load determination among those below a detectable threshold. Not accounting for such left-censoring appropriately can lead to biased parameter estimates in most data analysis. To properly adjust for left-censoring, this paper presents an extension of the Tobit model for fitting nonlinear dynamic mixed-effects models with skew distributions. Such extensions allow one to specify the conditional distributions for viral load response to account for left-censoring, skewness and heaviness in the tails of the distributions of the response variable. A Bayesian modeling approach via Markov Chain Monte Carlo (MCMC) algorithm is used to estimate model parameters. The proposed methods are illustrated using real data from an HIV/AIDS study.

    This study analyzes court records of a county-level obscenity trial in Austin, Texas, and the appeal of the guilty verdict beginning with a Texas appellate court up to the U.S. Supreme Court of two individuals who broadcast erotized AIDS and HIV safer sex information on a public-access cable television. The trial and appellate court decisions are reviewed in terms of argument themes, and the nature of sexual value controversy is outlined. Erotic materials often conflict with broad-based sexual and community values, and providing erotized HIV and AIDS information products can be a form of radical political action designed to force societal change. This study raises question as to how this trial and this type of informational product might affect the programs and activities of information resource centers, community-based organizations, libraries, and the overall mission of public health education.

    This case study investigates access to potable water in HIV/AIDS related home-based care households in five rural communities in Ngamiland, Botswana. Primary data collected from five villages consisted of two parts. The first survey collected household data on demographic and rural livelihood features and impacts of HIV/AIDS. A total of 129 households were selected using a two-stage stratified random sampling method. In the second survey, a total of 39 family primary and community care givers of continuously ill, bed-ridden or non-bed-ridden HIV/AIDS patients were interviewed. A detailed questionnaire, with closed and open-ended questions, was used to collect household data. In addition to using the questionnaire, data were also collected through participant observation, informal interviews and secondary sources. The study revealed that there are several sources of water for communities in Ngamiland such as off-plot, outdoor (communal) and on-plot outdoor and/or indoor (private) water connections, as well as other sources such as bowsed water, well-points, boreholes and open perennial/ephemeral water from river channels and pans. There was a serious problem of unreliable water supply caused by, among other things, the breakdown of diesel-powered water pumps, high frequency of HIV/AIDS related absenteeism, and the failure of timely delivery of diesel fuel. Some villages experienced chronic supply disruptions while others experienced seasonal or occasional water shortages. Strategies for coping with unreliability of water supply included economizing on water, reserve storage, buying water, and collection from river/dug wells or other alternative sources such as rain harvesting tanks in government institutions. The unreliability of water supply resulted in an increase in the use of water of poor quality and other practices of poor hygiene as well as a high opportunity cost of water collection. In such instances, bathing of patients was cut from twice daily to once or

    The amplification status of human epidermal growth factor receptors 2 (HER2) genes is strongly associated with clinical outcome in patients with breast cancer. The American Society of Clinical Oncology Tumor Marker Guidelines Panel has recommended routine testing of HER2 status on all newly diagnosed metastatic breast cancers since 2001. Although fluorescent in situ hybridization (FISH) technology provides superior accuracy as compared with other approaches, current manual FISH analysis methods are somewhat subjective, tedious, and may introduce interreader variability. The goal of this preliminary study is to develop and test a computer-aided detection (CAD) scheme to assess HER2 status using FISH images. Forty FISH images were selected for this study from our genetic laboratory. The CAD scheme first applies an adaptive, iterative threshold method followed by a labeling algorithm to segment cells of possible interest. A set of classification rules is then used to identify analyzable interphase cells and discard nonanalyzable cells due to cell overlapping and/or other image staining debris (or artifacts). The scheme then maps the detected analyzable cells onto two other gray scale images corresponding to the red and green color of the original image followed by application of a raster scan and labeling algorithms to separately detect the HER-2/neu ("red") and CEP17 ("green") FISH signals. A simple distance based criterion is applied to detect and merge split FISH signals within each cell. The CAD scheme computes the ratio between independent "red" and "green" FISH signals of all analyzable cells identified on an image. If the ratio is >= 2.0, the FISH image is assumed to have been acquired from a HER2+ case; otherwise, the FISH image is assumed to have been acquired from HER2- case. When we applied the CAD scheme to the testing dataset, the average computed HER2 amplification ratios were 1.06+/-0.25 and 2.53+/-0.81 for HER2- and HER2+ samples, respectively. The

SerVaas does not drive the traveling van that offers free AIDS testing. Rather, she often flies to meet it as it travels around the country, stopping at shopping malls and churches by prearrangement with local civic and religious groups. SerVaas denies saying that homosexuals are "deviants." "We have helped homosexuals for many years," she says, pointing out that although her group primarily tests people who have a low risk of being infected, such as recipients of blood transfusions and women who may become pregnant, members of high-risk groups such as homosexuals and drug addicts are not excluded.

  20. Health care and AIDS.

    The acquired immune deficiency syndrome (AIDS) is a harbinger for change in health care. There are many powerful forces poised to transform the industrialized health care structure of the twentieth century, and AIDS may act as either a catalyst or an amplifier for these forces. AIDS could, for example, swamp local resources and thereby help trigger national reform in a health care system that has already lost public confidence. AIDS can also hasten the paradigm shift that is occurring throughout health care. Many of the choices society will confront when dealing with AIDS carry implications beyond health care. Information about who has the disease, for example, already pits traditional individual rights against group interests. Future information systems could make discrimination based upon medical records a nightmare for a growing number of individuals. Yet these systems also offer the hope of accelerated progress against not only AIDS but other major health threats as well. The policy choices that will define society's response to AIDS can best be made in the context of a clearly articulated vision of a society that reflects our deepest values. PMID:10119289

  1. Group hypnotherapy versus group relaxation for smoking cessation: an RCT study protocol

    PubMed Central

    2012-01-01

    Background A significant number of smokers would like to stop smoking. Despite the demonstrated efficacy of pharmacological smoking cessation treatments, many smokers are unwilling to use them; however, they are inclined to try alternative methods. Hypnosis has a long-standing reputation in smoking cessation therapy, but its efficacy has not been scientifically proven. We designed this randomised controlled trial to evaluate the effects of group hypnosis as a method for smoking cessation, and we will compare the results of group hypnosis with group relaxation. Methods/Design This is a randomised controlled trial (RCT) to compare the efficacy of a single session of hypnosis with that of relaxation performed in groups of 8-15 smokers. We intend to include at least 220 participants in our trial. The inclusion criteria include smoking at least 5 cigarettes per day, not using other cessation methods and being willing to quit smoking. The intervention is performed by a trained hypnotist/relaxation therapist. Both groups first receive 40 min of mental preparation that is based on motivational interviewing. Then, a state of deep relaxation is induced in the hypnosis condition, and superficial relaxation is induced in the control condition. Suggestions are made in the hypnosis condition that aim to switch the mental self-image of the participants from that of smokers to that of non-smokers. Each intervention lasts for 40 min. The participants also complete questionnaires that assess their smoking status and symptoms of depression and anxiety at baseline, 2 weeks and 6 months post-intervention. In addition, saliva samples are collected to assess cotinine levels at baseline and at 6 months post-intervention. We also assess nicotine withdrawal symptoms at 2 weeks post-intervention. Discussion To the best of our knowledge, this RCT is the first to test the efficacy of group hypnosis versus group relaxation. Issues requiring discussion in the outcome paper include the lack of

    We study the dynamics of the group of Atira asteroids, characterized by aphelion distance Q < 0.983 au. This group has a significant observational bias, and their number is expected to be an order of magnitude larger than is known today. Due to their orbital configuration, these asteroids may represent a potential danger to the Earth. Here, we construct dynamical maps of the region between 0.2 and 0.98 au using a simple chaos indicator, the mean standard deviation in semimajor axis, and also analyse the behaviour of the real Atira orbits by means of the diffusion coefficient in semimajor axis. Our results indicate that Atira asteroids are located in the most unstable regions of the inner Solar system, and their stability is determined by close encounters and collisions with Mercury, Venus, and the Earth. A fraction of the known Atiras may represent a potential threat to the Earth over a few 105 yr of evolution. We found two islands of low-eccentricity stable orbits that might harbour a long-lasting sub-population of Atiras not yet observed.

    Overweight and obesity are a major concern in young adults. Technology has been integrated into many weight loss interventions; however little is known about the use of this technology in young adults. The purpose of this study was to explore through focus group sessions the opinions of young adults on the use of technology for weight loss. A total of 17 young adults, between 18 and 25 years of age, participated in three focus group sessions. Major results indicated that young adults have very little knowledge on the use of Smartphone technology for weight loss but would like to use this type of technology to help them lose weight. Results also indicated that young adults struggle to make healthy food choices and have priorities that outweigh exercise and they need support and guidance to make better decisions. In conclusion, young adults would be open to using Smartphone technology for weight loss but also need feedback and guidance to help make healthy decisions. PMID:25789170

    BACKGROUND: The uptake of the combined measles, mumps and rubella immunisation (MMR) in Britain has fallen since 1998, when a link was hypothesised with the development of bowel disorders and childhood autism. Despite reassurances about the safety of MMR, uptake levels remain lower than optimal. We need to understand what influences parents' decisions on whether to accept MMR or not so that health professionals can provide a service responsive to their needs. AIM: To investigate what influences parents' decisions on whether to accept or refuse the primary MMR immunisation and the impact of the recent controversy over its safety. DESIGN: Qualitative study using focus group discussions. SETTING: Forty-eight parents, whose youngest child was between 14 months and three years old, attended groups at community halls in six localities in Avon and Gloucestershire. METHODS: Purposive sampling strategy was used to include parents from a variety of socioeconomic backgrounds. Three groups comprised parents who had accepted MMR and three groups comprised parents who had refused MMR. Data analysis used modified grounded theory techniques incorporating the constant comparative method. RESULTS: All parents felt that the decision about MMR was difficult and stressful, and experienced unwelcome pressure from health professionals to comply. Parents were not convinced by Department of Health reassurances that MMR was the safest and best option for their children and many had accepted MMR unwillingly. Four key factors influenced parents' decisions: (a) beliefs about the risks and benefits of MMR compared with contracting the diseases, (b) information from the media and other sources about the safety of MMR, (c) confidence and trust in the advice of health professionals and attitudes towards compliance with this advice, and (d) views on the importance of individual choice within Government policy on immunisation. CONCLUSIONS: Parents wanted up-to-date information about the risks and

    Purpose Examine incidence and factors associated with loss to follow-up (LTFU) in the AIDS Clinical Trials Group (ACTG) Longitudinal Linked Randomized Trials (ALLRT) cohort. Method ALLRT is a prospective cohort of HIV-infected persons randomized to ARV regimens/strategies in ACTG trials and followed long-term after the trial ends. Person-years were calculated from ALLRT entry until LTFU (defined using off-study reasons or ≥3 consecutive missed visits), death/severe debilitation/site closures, or June 2009 (censored). Poisson regression was used to examine LTFU factors separately among participants who were ARV-naïve or ARV-experienced at trial entry. Results Among 4630 participants (22,524 person-years), 1140 were lost to follow-up, 237 died, 29 were severely debilitated, and 443 were at sites that closed. The LTFU incidence was 5.5 and 4.2 per 100 person-years among previously ARV-naïve and ARV-experienced participants, respectively. In both groups, age≤50, site location, being off-ARVs and viral load ≥400 copies/ml were associated with a higher risk of LTFU. Among ARV-naïves, male sex, education<16 years, IV drug use and cigarette smoking were also associated with LTFU. Conclusion Knowledge of differential LTFU can help researchers identify participants at risk of LTFU in longitudinal HIV cohorts and design retention strategies, thereby limiting study bias. The identified factors should be included in inverse probability of weighting models to account for LTFU. PMID:22044855

    An evaluation is presented of the approach and landing performance of a Kalman filter aided inertial navigation system using flight data obtained from a series of approaches and landings of the CV-340 aircraft at an instrumented test area. A description of the flight test is given, in which data recorded included: (1) accelerometer signals from the platform of an INS; (2) three ranges from the Ames-Cubic Precision Ranging System; and (3) radar and barometric altimeter signals. The method of system evaluation employed was postflight processing of the recorded data using a Kalman filter which was designed for use on the XDS920 computer onboard the CV-340 aircraft. Results shown include comparisons between the trajectories as estimated by the Kalman filter aided system and as determined from cinetheodolite data. Data start initialization of the Kalman filter, operation at a practical data rate, postflight modeling of sensor errors and operation under the adverse condition of bad data are illustrated.

    1968-01-01

    A number of strains of oxidase-positive moraxellas and of neisserias related to Neisseria catarrhalis were characterized with respect to a number of nutritional and physiological properties and could be assigned to several species or species groups on the basis of their phenotypic traits. This grouping was consistent with that established by Bövre on the basis of transformation frequencies for streptomycin resistance. It is proposed to reserve the generic name Moraxella for the oxidase-positive rodshaped organisms, and a redescription of the genus is offered. Following the recent taxonomic proposals of Bövre and Henriksen, the specific name Moraxella osloensis is applied to the nutritionally unexacting strains that accumulate poly-β-hydroxybutyrate as carbon reserve. The nutritionally exacting strains are assigned to three distinct groups which can be regarded as separate species or as varieties of M. lacunata. The epithets applicable to these groups appear to be lacunata, nonliquefaciens, and bovis. The “false neisserias” could be assigned to at least three subgroups, one of which constitutes the clearly defined entity, N. catarrhalis, which could be distinguished from N. caviae and N. ovis.

    Space station habitability was studied by investigating crew activity routines, proximities, ergonomic envelopes, and group volumes. Ten alternative schematic interior designs were proposed. Preliminary conclusions include: (1) in-service interior modifications may be necessary and should be planned for; (2) design complexity will be increased if the module cluster is reduced from five to three; (3) the increased crew circulation attendant upon enhancement of space station activity may produce human traffic bottlenecks and should be planned for; (4) a single- or two-person quiet area may be desirable to provide crew members with needed solitude during waking hours; and (5) the decision to choose a two-shift or three-shift daily cycle will have a significant impact on the design configuration and operational efficiency of the human habitat.

    2011-01-01

    Background Swaziland is experiencing the world’s worst HIV and AIDS epidemic. Prevalence rose from four percent of antenatal clinic attendees in 1992 to 42.6 percent in 2004. The Report ‘Reviewing ‘Emergencies’ for Swaziland: Shifting the Paradigm in a New Era’ published in 2007 bought together social and economic indicators. It built a picture of the epidemic as a humanitarian emergency, requiring urgent action from international organisations, donors, and governments. Following a targeted communications effort, the report was believed to have raised the profile of the issue and Swaziland - a success story for HIV and AIDS research. Methods Keen to understand how, where and why the report had an impact, Health Economics and HIV/AIDS Research Division commissioned an assessment to track and evaluate the influence of the research. This tapped into literature on the significance of understanding the research-to-policy interface. This paper outlines the report and its impact. It explores key findings from the assessment and suggests lessons for future research projects. Results The paper demonstrates that, although complex, and not without methodological issues, impact assessment of research can be of real value to researchers in understanding the research-to-policy interface. Conclusion Only by gaining insight into this process can researchers move forward in delivering effective research. PMID:21679390

    Introduction Research investigating frequent sickness absence (3 or more episodes per year) is scarce and qualitative research from the perspective of frequent absentees themselves is lacking. The aim of the current study is to explore awareness, determinants of and solutions to frequent sickness absence from the perspective of frequent absentees themselves. Methods We performed a qualitative study of 3 focus group discussions involving a total of 15 frequent absentees. Focus group discussions were audiotaped and transcribed verbatim. Results were analyzed with the Graneheim method using the Job Demands Resources (JD–R) model as theoretical framework. Results Many participants were not aware of their frequent sickness absence and the risk of future long-term sickness absence. As determinants, participants mentioned job demands, job resources, home demands, poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Managing these factors and improving communication (skills) were regarded as solutions to reduce frequent sickness absence. Conclusions The JD–R model provided a framework for determinants of and solutions to frequent sickness absence. Additional determinants were poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Frequent sickness absence should be regarded as a signal that something is wrong. Managers, supervisors, and occupational health care providers should advise and support frequent absentees to accommodate job demands, increase both job and personal resources, and improve health rather than express disapproval of frequent sickness absence and apply pressure regarding work attendance.

    Would you like to know when someone has dropped an undesirable executable binary on our system? What about something less malicious such as a software installation by a user? What about the user who decides to install a newer version of mod_perl or PHP on your web server without letting you know beforehand? Or even something as simple as when an undocumented config file change is made by another member of the admin group? Do you even want to know about all the changes that happen on a daily basis on your server? The purpose of an intrusion detection system (IDS) is to detect unauthorized, possibly malicious activity. The purpose of a host-based IDS, or file integrity checker, is check for unauthorized changes to key system files, binaries, libraries, and directories on the system. AIDE is an Open Source file and directory integrity checker. AIDE will let you know when a file or directory has been added, deleted, modified. It is included with the Red Hat Enterprise 6. It is available for other Linux distros. This is a case study describing the process of configuring AIDE on an out of the box RHEL6 installation. Its goal is to illustrate the thinking and the process by which a useful AIDE configuration is built.

    2010-06-01

    Fatigue affects many persons after cerebrovascular accident, particularly those with mild stroke. A qualitative methodology using focus groups with 19 community-living post-stroke survivors was utilized to explore the occupational impact of fatigue as communicated by the participants. Although self-report of a small sample of the United States' post-stroke population will have limitations in generalizability, this study identifies specific health-related quality of life issues that can occur with post-stroke fatigue. The participants felt unprepared for the fatigue phenomenon and struggled to adapt, with fatigue having a debilitating influence upon daily occupational performance and roles, including social participation, return to work, driving, reading and sleeping. The participants indicated that exercise (such as walking and water aerobics) and use of assistive technology were helpful strategies in reducing fatigue. The occupational performance and role impact identified by participants in this study can inform the design of effective occupational therapy interventions and further quantitative study of persons with post-stroke fatigue.

    This study examined the use of deliberately anthropomorphic automation on younger and older adults' trust, dependence and performance on a diabetes decision-making task. Research with anthropomorphic interface agents has shown mixed effects in judgments of preferences but has rarely examined effects on performance. Meanwhile, research in automation has shown some forms of anthropomorphism (e.g. etiquette) have effects on trust and dependence on automation. Participants answered diabetes questions with no-aid, a non-anthropomorphic aid or an anthropomorphised aid. Trust and dependence in the aid was measured. A minimally anthropomorphic aide primarily affected younger adults' trust in the aid. Dependence, however, for both age groups was influenced by the anthropomorphic aid. Automation that deliberately embodies person-like characteristics can influence trust and dependence on reasonably reliable automation. However, further research is necessary to better understand the specific aspects of the aid that affect different age groups. Automation that embodies human-like characteristics may be useful in situations where there is under-utilisation of reasonably reliable aids by enhancing trust and dependence in that aid. Practitioner Summary: The design of decision-support aids on consumer devices (e.g. smartphones) may influence the level of trust that users place in that system and their amount of use. This study is the first step in articulating how the design of aids may influence user's trust and use of such systems. PMID:22799560

    HIV+ substance dependent individuals (SDIs) make significantly poorer decisions compared with HIV− SDIs, but the neurocognitive mechanisms underlying this impairment have not been identified. We administered the Iowa Gambling Task, a measure of decision making under uncertain risk, and the Cups Task, a measure of decision making under specified risk, to a group of 56 HIV+ and 23 HIV− men who have sex with men (MSMs) with a history of substance dependence enrolled in the Multicenter AIDS Cohort Study. The IGT provides no explicit information regarding the contingencies for each possible choice, and the probability of each outcome remains ambiguous at least for the early trials; in contrast, the Cups Task provides explicit information about the probability of each outcome. The HIV+ group made significantly poorer decisions on the IGT compared with the HIV− group. Cups Task performance did not differ significantly between HIV− and HIV+ groups. Exploratory analyses of the IGT data suggested that HIV+ subjects tended to perform more poorly during the early learning phase when uncertainty about specific outcomes was greatest. Additionally, performance on the final two trial blocks was significantly correlated with Stroop Interference scores, suggesting IGT performance is driven increasingly by executive control during the later portion of the task. Potential cognitive mechanisms to be explored in later studies are discussed, including impairment in implicit learning processing PMID:23701366

  6. Does expressed acceptance reflect genuine attitudes? A bogus pipeline study of the effects of mortality salience on acceptance of a person with AIDS.

    PubMed

    Grover, Kristin W; Miller, Carol T

    2012-01-01

    The present study examined whether expressed acceptance of a person with AIDS reflects genuine acceptance or a desire to appear to be accepting. Theory and research on the effects of mortality salience on acceptance of stigmatized people provided the framework for investigating this question. After writing about death or another aversive topic, participants indicated their acceptance of a target with AIDS while connected to physiological equipment that they believed could detect lies (bogus pipeline) or was simply measuring physiological responses to participation in the study. As predicted, participants in the mortality salience/bogus pipeline condition indicated significantly less acceptance of the target with AIDS than participants in the other three conditions, suggesting that acceptance of a person with AIDS is at least partially a result of wanting to appear to be accepting, without necessarily genuinely accepting someone with AIDS.

    2004-08-01

    This study tested the hypothesis that dissipative efficiency of tropical tree species could be an ecological advantage in the forest succession process. Daily leaf gas exchanges of a pioneer species (Guazuma ulmifolia) and a late successional species (Cariniana legalis) were evaluated under well-irrigated conditions and by withholding irrigation. Analyses of network connectance (Cg) and plant autonomy (At) were carried out in order to assess metabolic network changes in response to environmental perturbation. As a global estimation of latent heat dissipation, the capacity to both maintain and cool leaf temperature in response to air temperature changes (deltaT = T degrees Cair - T degrees Cleaf) was evaluated. The changes observed in both the systemic parameters (Cg and At) and the physiological ones brought about by water deficit, associated with discrepant growth rates between both species, suggested that the initial formation of gap canopies composed by pioneer species could simply be a result of the higher photosynthetic rates of these species, and not necessarily because late successional species cannot cope with such a heterogeneous environment as that of a gap. Our results indicate that, in the absence of water constraints, the highest CO2 assimilation rates of pioneer species are supported by the efficiency of the whole dissipative structure, involving both degradation and dissipative processes. As a practical result, our study suggests the deltaT analysis in order to evaluate the efficiency of dissipative structures and as a aid in characterizing functional groups. PMID:15620011

    The existence of an idempotent generator for group codes or group ring codes in FqG plays a very important role in determining the minimal distance of the respective code. Some necessary and sufficient conditions for a group ring element to be an idempotent in F2Cn are investigated in this paper. The main result in this paper is the affirmation of the existence of finitely many basis idempotents which gives a full identification of all idempotents in every binary cyclic group ring F2Cn. All the basis idempotents in F2Cn are able to be found by partitioning the largest idempotent's support.

    Migrant women in China are disproportionately affected by HIV/AIDS. This study described HIV/AIDS-related knowledge and behaviors among married migrant women in Shandong province in comparison to non-migrant local women and identified factors associated with HIV testing history and extramarital sex among married migrant women. A probability-based sample of 1,076 migrant and 1,195 local women were included in the analyses. Compared to local women, married migrant women had lower levels of HIV/AIDS knowledge and were more likely to have had premarital sex, extramarital sex, history of sexually transmitted diseases, and drug use. Less than a quarter of migrant women used condoms consistently in extramarital sex. Only 31.0 % of married migrant women had ever tested for HIV, and the rate of premarital HIV testing was very low. Multivariable analysis showed that married migrant women with a history of extramarital sex were more likely to be from Yunnan province, be living in Yantai city, be in their first marriage, have lower family income, have poor relationship with spouses, use drug, have a history of sexually transmitted diseases, and have lower social support. Our findings provide further evidence that married migrant women are at higher risk for HIV infection and that targeted interventions need to be developed for this population. PMID:25323941

    We examined the emergence of CXCR4 (i.e., X4) tropism in 67 male human immunodeficiency virus type 1 (HIV-1) seroconverters from the Multicenter AIDS Cohort Study (MACS) who were selected to reflect the full spectrum of rates of HIV-1 disease progression. A mean of 10 serial samples per donor were evaluated by a laboratory-validated, commercially available assay to determine phenotypic coreceptor use. A total of 52% of men had dual- or mixed-tropic HIV-1 detected at 1 or more of the time points tested. Use of X4 by HIV-1 was detected more frequently among men who developed AIDS (defined as a CD4+ T cell count of < 200 cells/μL and/or an AIDS-defining illness)≤11 years after seroconversion than among those who did not (P = .005), as well as among men who exhibited a total T cell count decline (i.e., a CD3+ inflection point), compared with those who did not (P = .03). For men in whom both X4 virus and an inflection point were detected, emergence of X4 virus preceded the inflection point by a median of 0.83 years. The median CD4+ T cell count at first detection of X4 viruses before the onset of AIDS was 475 cells/μL. We conclude that HIV-1 variants that used X4 frequently emerged at high CD4+ T cell counts and may contribute to the decrease in T cell numbers during late HIV-1 infection. PMID:18783316

    2009-01-01

    Background Panic attacks are common, and while they are not life-threatening events, they can lead to the development of panic disorder and agoraphobia. Appropriate help at the time that a panic attack occurs may decrease the fear associated with the attack and reduce the risk of developing an anxiety disorder. However, few people have the knowledge and skills required to assist. Simple first aid guidelines may help members of the public to offer help to people who experience panic attacks. Methods The Delphi method was used to reach consensus in a panel of experts. Experts included 50 professionals and 6 people who had experience of panic attacks and were active in mental health advocacy. Statements about how to assist someone who is having a panic attack were sourced through a systematic search of both professional and lay literature. These statements were rated for importance as first aid guidelines by the expert and consumer panels and guidelines were written using the items most consistently endorsed. Results Of 144 statements presented to the panels, 27 were accepted. These statements were used to develop the guidelines appended to this paper. Conclusion There are a number of actions which are considered to be useful for members of the public to do if they encounter someone who is having a panic attack. These guidelines will be useful in revision of curricula of mental health first aid programs. They can also be used by members of the public who want immediate information about how to assist someone who is experiencing panic attacks. PMID:19664244

  19. What about N? A methodological study of sample-size reporting in focus group studies

    PubMed Central

    2011-01-01

    Background Focus group studies are increasingly published in health related journals, but we know little about how researchers use this method, particularly how they determine the number of focus groups to conduct. The methodological literature commonly advises researchers to follow principles of data saturation, although practical advise on how to do this is lacking. Our objectives were firstly, to describe the current status of sample size in focus group studies reported in health journals. Secondly, to assess whether and how researchers explain the number of focus groups they carry out. Methods We searched PubMed for studies that had used focus groups and that had been published in open access journals during 2008, and extracted data on the number of focus groups and on any explanation authors gave for this number. We also did a qualitative assessment of the papers with regard to how number of groups was explained and discussed. Results We identified 220 papers published in 117 journals. In these papers insufficient reporting of sample sizes was common. The number of focus groups conducted varied greatly (mean 8.4, median 5, range 1 to 96). Thirty seven (17%) studies attempted to explain the number of groups. Six studies referred to rules of thumb in the literature, three stated that they were unable to organize more groups for practical reasons, while 28 studies stated that they had reached a point of saturation. Among those stating that they had reached a point of saturation, several appeared not to have followed principles from grounded theory where data collection and analysis is an iterative process until saturation is reached. Studies with high numbers of focus groups did not offer explanations for number of groups. Too much data as a study weakness was not an issue discussed in any of the reviewed papers. Conclusions Based on these findings we suggest that journals adopt more stringent requirements for focus group method reporting. The often poor and

  20. Geochemical Study of Lichens in Tatun Volcano Group, North Taiwan

    2015-04-01

    Tatun Volcano Group (TVG) is located in the northwest of Taipei, the capital of Taiwan. Although the last activity was 200000 years ago, it is critical to monitor TVG because it is nearby metropolitan area. This study is part of the monitoring program and attempts to observe the geochemical relationship between lichen and volcanic gas. Lichens have been extensively used for monitoring atmospheric quality. Lichen can live in critical environments and can accumulate metals from atmosphere due to lack of excretion mechanism. Moreover, lichen can live long and growth in a low rate; therefore, lichen geochemistry can represent an average in a long term manner. In TVG, fruticose lichen can be seldom found due to the high concentration of SO2 in the atmosphere. However, foliose lichen and crustose lichen are not rare in the study area. In this study, lichens were collected from TVG and Nan-ao Trail which is in non-volcanic area. The cations were measured by ICP-MS. The geochemical results were analyzed by principal components analysis (PCA). It shows that there is no significant difference among non-volcanic lichens and the non-volcanic lichens are located at an end-member of two distinct trends. It is believed that the non-volcanic lichens indicate a geochemical baseline in north Taiwan and two trends may represent the mixing between two different types of volcanic gases in TVG and geochemical baseline. In this study, rare earth elements (REEs) were also measured. The results of non-volcanic and TVG lichens were normalized by North America Shale and TVG andesite, respectively. Both obtain a flat REE pattern, which confirm that TVG lichens receive metals from volcanic origin and non-volcanic lichens give information of background geochemistry in north Taiwan. In addition, a middle REE enrichment and distinct Ce negative anomaly can be observed. According to the previous studies, middle REE enrichment may be achieved by the selected adsorption of middle REEs by organic

  1. Older Inmates’ Pursuit of Good Health: A Focus Group Study

    PubMed Central

    Steffensmeier, Darrell

    2012-01-01

    A multitude of intersecting factors including the graying of the broader society, a paradigm shift away from rehabilitation, fewer opportunities for parole, and retrospective prosecutions contribute to an exponential increase in number of geriatric inmates. Elderly prisoners are likely to live in small tight quarters with other inmates, have two or more chronic health conditions, and encounter multiple barriers impeding health promotion while incarcerated. The purpose of this study was to identify perceived challenges to the health of older male inmates and to explore their self-care strategies. Focus group methodology was used. Data were collected from 42 male inmates age 50 and over who were aging in place and living with comorbidity. Cost issues, prison personnel and policies, food concerns, fellow inmates, and personal barriers all challenged older inmates’ abilities to maintain their health in prison. However, these older inmates engaged in a variety of self-care strategies, including: accessing resources and support; staying positive; managing diet and weight; engaging in physical activity; and protecting self. A key motivator for pursuing good health was to be respected and perceived as healthy and strong by fellow inmates. Looking to the future, development and testing of programs to enhance inmates' self-management of chronic conditions and to facilitate health promotion are in order. PMID:20795581

  2. Global and local alignments in HIV/AIDS prevention trainings: a case study from Burkina Faso.

    PubMed

    Drescher, Martina

    2007-01-01

    This article presents a linguistic analysis of data from an ongoing research project exploring HIV/AIDS education in West African Burkina Faso. I argue that we can identify different, sometimes even competing, discourses about the disease in prevention interactions. Thus, communication about HIV/AIDS in Burkina Faso--and probably in most of the Sub-Saharan countries--might be characterized by what I will call, with reference to Bakhtin, discursive heteroglossia. There is clear evidence of such discursive heteroglossia, that is, the participants' alignment to local and global HIV discourses, deployed in the communication of health workers. In my analysis of peer educators training sessions, I draw on theoretical and methodological principles from discourse analysis and interactional linguistics. I focus on the linguistic devices and conversational strategies the participants use to indicate the relevance of the local or the global discourses. Three particular devices--namely, metaphors, epistemic and evidential markers, and word explanations--will be examined in a more detailed way. I will also show how the local and the global interweave at different levels of prevention discourse. PMID:17714039

    Objective This study's aims were to explore the views of special constables in the London metropolitan police force concerning their obligations and skills as first aiders. Background The metropolitan police force provides police officers to act as first responders to emergency calls made by the public. Special constables act with the same powers and responsibility as police officers and are required to deal with incidents involving medical emergencies. Setting West London Police Station. Participants Fifteen special constables entered and completed the study. Methods and Outcome Measures A qualitative study involving semistructured interviews, participant observation, and reflective work. The outcome measures were the themes derived from the ‘thematic framework approach’ to analysis. Results Four main themes were identified. (1) ‘Our responsibility?’—Special constables felt they had a responsibility, but were unsure of the origin of this responsibility, with many feeling it stemmed from public expectation. (2) ‘Confidence’—Special constables had mixed feelings regarding their confidence in first aid scenarios and many felt that more could be done to improve their confidence. (3) ‘Training needs’—Many felt the current training system was lacking in several ways including regularity, teaching and content. (4) ‘Personal first aid knowledge’—Special constables were disappointed with their past performances. Conclusions Owing to the small size of this study, the conclusions are limited; however, if the findings are confirmed by larger studies, they suggest the need to improve the confidence of special constables in first aid situations.

    Group A Streptococcus (GAS) M protein is an important virulence factor and potential vaccine antigen, and constitutes the basis for strain typing (emm-typing). Although >200 emm-types are characterized, structural data were obtained from only a limited number of emm-types. We aim to evaluate the sequence diversity of near-full-length M proteins from worldwide sources and analyse their structure, sequence conservation and classification. GAS isolates recovered from throughout the world during the last two decades underwent emm-typing and complete emm gene sequencing. Predicted amino acid sequence analyses, secondary structure predictions and vaccine epitope mapping were performed using MUSCLE and Geneious software. A total of 1086 isolates from 31 countries were analysed, representing 175 emm-types. emm-type is predictive of the whole protein structure, independent of geographical origin or clinical association. Findings of an emm-type paired with multiple, highly divergent central regions were not observed. M protein sequence length, the presence or absence of sequence repeats and predicted secondary structure were assessed in the context of the latest vaccine developments. Based on these global data, the M6 protein model is updated to a three representative M protein (M5, M80 and M77) model, to aid in epidemiological analysis, vaccine development and M protein-related pathogenesis studies.

    Strictly speaking, implantable hearing aids are technical systems that process audiological signals and convey these by direct mechanical stimulation of the ossicular chain or cochlea. They have certain benefits over conventional hearing aids in terms of wearing comfort and general acceptance. As current studies lack convincing audiological results, the indications for implantable hearing aids are primarily of medical or cosmetic nature. To date, three systems are available in Germany: Vibrant Soundbridge®, Carina®, and Esteem®. Because the performance of the different implantable and nonimplantable hearing systems together with various surgical procedures are currently undergoing major changes, audiological indications may also develop in the future.

    Introduction: Social capital is increasingly used in relation to health issues, particularly in sexually transmitted diseases/infections and health behaviors. Experiences indicated that social capital can contribute in changing HIV related risk behaviors and a decline of HIV infection through social groups and networking and make more effective use of HIV/AIDS prevention, care, and treatment services. We aimed to assess social capital in these persons through a quantitative study. Method: This cross-sectional study was performed with a convenience sample of 300 people living HIV/AIDS referred to a counseling center of behavioral diseases, in Imam Khomeini Hospital, in Tehran, the capital of Iran, during September 2011 to May 2012. Data collection tools were a demographic questionnaire and World Bank Social Capital Questionnaire (SC-IQ). The analysis of data was performed by the SPSS statistic software version 18. To identify factors influencing social capital in participations, Pearson correlation coefficient, ANOVA, t-test, and a multiple regression were applied. The significant level was considered 0.05 in this study. Results: 165 (55%) were male and the rest female. The mean age of participants was 34.3±7.5. The mean score of total social capital was 2.34±0.5 in all participants. The domain of individual trust had the highest mean score (2.53±0.66). The lowest mean score was related to the domain of social trust and associative relations (2.23±0.62). Variables such as ethnicity, age, and middle economic status had a significant impact on the domain of individual trust so that the mean score of this component of social capital was lower among women (0.396) than men. Factors affecting total social capital were ethnicity and middle economic status. Conclusion: Finding emphasized on the role of economic status, ethnicity and gender in persons living with HIV/AIDS. Thus recommended that policy makers and program managers consider social groups and networks

    Background Staff shortages could harm the provision and quality of health care in Uganda, so staff retention and motivation are crucial. Understanding the impact of HIV/AIDS on staff contributes to designing appropriate retention and motivation strategies. This research aimed 'to identify the influence of HIV/AIDS on staff working in general hospitals at district level in rural areas and to explore support required and offered to deal with HIV/AIDS in the workplace'. Its results were to inform strategies to mitigate the impact of HIV/AIDS on hospital staff. Methods A cross-sectional study with qualitative and quantitative components was implemented during two weeks in September 2005. Data were collected in two government and two faith-based private not-for-profit hospitals purposively selected in rural districts in Uganda's Central Region. Researchers interviewed 237 people using a structured questionnaire and held four focus group discussions and 44 in-depth interviews. Results HIV/AIDS places both physical and, to some extent, emotional demands on health workers. Eighty-six per cent of respondents reported an increased workload, with 48 per cent regularly working overtime, while 83 per cent feared infection at work, and 36 per cent reported suffering an injury in the previous year. HIV-positive staff remained in hiding, and most staff did not want to get tested as they feared stigmatization. Organizational responses were implemented haphazardly and were limited to providing protective materials and the HIV/AIDS-related services offered to patients. Although most staff felt motivated to work, not being motivated was associated with a lack of daily supervision, a lack of awareness on the availability of HIV/AIDS counselling, using antiretrovirals and working overtime. The specific hospital context influenced staff perceptions and experiences. Conclusion HIV/AIDS is a crucially important contextual factor, impacting on working conditions in various ways. Therefore

  9. A cross-sectional study to assess knowledge about HIV/AIDS transmission and prevention measures in company workers in Ecuador

    2013-01-01

    Background HIV/AIDS was first reported in Ecuador in 1984 and its prevalence has been increasing ever since. In 2009, the National AIDS Program reported 21,810 HIV/AIDS cases and confirmed that the worker population was amongst the most affected groups. The objective of this study was to assess knowledge about HIV transmission and prevention measures in company workers in Ecuador. Methods A cross-sectional survey based on a random sample of 115 companies (1,732 workers), stratified by three large provinces and working sectors (commerce, manufacturing and real estate) was conducted. A validated instrument developed by Family Health International was used to evaluate HIV prevention knowledge and common local misconceptions about HIV transmission. Descriptive statistics, chi square test and logistic regression analysis were performed using SAS. Results Incorrect knowledge about HIV/AIDS transmission were found in 49.1% (95% CI: 46.6–51.6) of subjects. Incorrect knowledge was higher among males (OR = 1.73 [1.39–2.15]), older subjects (OR = 1.35 [1.02–1.77]), subjects with lower education (OR = 3.72 [2.44–5.65]), manual labor workers (OR = 2.93 [1.82–4.73]) and subjects without previous exposure to HIV intervention programs (OR = 2.26 [1.79–2.86]). Incorrect knowledge about preventive measures was found among 32.9% (95%CI: 30.6–35.2) of respondents. This proportion was higher among subjects with lower education (OR = 2.28 [1.52–3.43]), married subjects (OR = 1.34 [1.07–1.68]), manual labor workers (OR = 1.80 [1.34–2.42]), and subjects not previously exposed to HIV intervention programs (OR = 1.44 [1.14–1.83]). Conclusions HIV intervention programs targeting company workers are urgently needed to improve knowledge and reduce HIV transmission in Ecuador. PMID:23410074

    The authors explored the efficacy of a randomized controlled trial to assess the potential benefits of psychological first aid (PFA) compared with a social acknowledgement condition in a sample of 42 participants who spoke about a stressful life event. Demographics and standardized questionnaires, including the state version of the State Trait Anxiety Inventory Scale and the Brief Profile of Mood States, assessed anxiety and mood state. Those in the PFA group evidenced significantly lower anxiety scores at 30-minute postdisclosure than at baseline and, although not significant, showed lowered distressed mood compared with baseline at 30-minute postdisclosure. Those in the social acknowledgment condition evidenced increases in anxiety and distressed mood scores, albeit not significantly, at 30 minutes post disclosure compared with their baseline scores. These results provide preliminary empirical evidence for the efficacy of PFA, and implications for intervention and additional assessment are suggested. PMID:26919301

    A pilot aid -- a kinesthetic-tactual compensatory display -- for assisting novice pilots in various inflight situations has undergone preliminary inflight testing. The efficacy of this display, as compared with two types of visual displays, was evaluated in both a highly structured approach-and-landing task and a less structured test involving tight turns about a point. In both situations, the displayed quantity was the deviation (alpha sub 0 - alpha) in angle at attack from a desired value alpha sub 0. In the former, the performance with the tactual display was comparable with that obtained using a visual display of (alpha sub 0 - alpha), while in the later, substantial improvements (reduced tracking error (55%), decreased maximum altitude variations (67%), and decreased speed variations (43%)), were obtained using the tactual display. It appears that such a display offers considerable potential for inflight use.

The creative thoughts and actions of those people most threatened by HIV/AIDS, and the thoughts and actions of science, have shaped both each other and the virus. The virus has reacted through mutation in ways that mimic strategic intelligence. The dialectics of capital and states has shaped these interactions and, in some cases, been shaped by them.

    This paper presents a case study of the traditional treatment of a Q'eqchi' Maya man in southern Belize in 2011 who is suffering from AIDS-related sickness. The purpose is to detail the empirical nature of Q'eqchi' Maya medicine, distinguishing between manifest and latent empiricism, as evidenced in the healers evolving attempts to treat the patient in the absence of knowledge of his biomedical diagnosis. The paper argues for a more complete understanding of the empirical nature of much Indigenous healing, which parallels aspects of scientific medicine, and for better collaboration among traditional healers and biomedical practitioners in strongly Indigenous areas.

    1984-01-01

    The effect on selected polyimide properties when pendant alkyl groups were attached to the polymer backbone was investigated. A series of polymers were prepared using benzophenone tetracarboxylic acid dianhydride (BTDA) and seven different p-alkyl-m,p'-diaminobenzophenone monomers. The alkyl groups varied in length from C(1) (methyl) to C(9) (nonyl). The polyimide prepared from BTDA and m,p'-diaminobenzophenone was included as a control. All polymers were characterized by various chromatographic, spectroscopic, thermal, and mechanical techniques. Increasing the length of the pendant alkyl group resulted in a systematic decrease in glass transition temperature (Tg) for vacuum cured films. A 70 C decrease in Tg to 193 C was observed for the nonyl polymer compared to the Tg for the control. A corresponding systematic increase in Tg indicative of crosslinking, was observed for air cured films. Thermogravimetric analysis revealed a slight sacrifice in thermal stability with increasing alkyl length. No improvement in film toughness was observed.

    In vehicle, there are many ECU(Electronic Control Unit)s, and ECUs are connected to networks such as CAN, LIN, FlexRay, and so on. AUTOSAR COM(Communication) which is a software platform of AUTOSAR(AUTomotive Open System ARchitecture) in the international industry standards of automotive electronic software processes signals and signal groups for data communications between ECUs. Real-time and reliability are very important for data communications in the vehicle. Therefore, in this paper, we analyze functions of signals and signal groups used in COM, and represent that functions of signal group are more efficient than signals in real-time data synchronization and network resource usage between the sender and receiver.

    Various studies have reported a huge increase in the numbers of orphaned adolescents in Sub-Saharan Africa and its effects on their psychological, emotional and behavioural development. Yet, their needs are seldom recognised or adequately addressed in policy and programmes.This article uses a qualitative study to report the experiences of 11 orphaned adolescents (5 boys and 6 girls aged between 15 and 18 years) affected by HIV and AIDS in a secondary school (in Atteridgeville, Pretoria, South Africa) and the school support provided by them. The primary data-generation strategies were informal interviews and the Beck Youth Inventories-II (BYI-II) (adopted to measure the participants' level of emotional, behavioural and psychological problems). All interview transcriptions with the participants were thematically analysed. BYI-II data were subjected to T scores (in percentages) to know the participant's psychological, behavioural and emotional problems in order to compare it with their perceptions on the degree of support provided by the school. Result shows that participants have a high prevalence of psychological, behavioural and emotional problems and that the school support provided to them (teachers' support, the general school environment and the degree of discrimination, labelling and bullying that exists in the school) was not sufficient. The participants, however, reported a high level of support from the principal. In conclusion, we have suggested the urgent need for teachers to acquire and possess basic knowledge and skills in caring and paying attention to learners affected by HIV and AIDS and for government agencies and NGOs working with HIV-and AIDS-affected children, to focus on proposals that address the psychological, behavioural and emotional problems in such affected adolescents.

    Individual behaviour change interventions and technological approaches to HIV prevention can only be effective over time if the broader social environment in which health-related decisions are made facilitate their uptake. People need to be not only willing but also able to take up and maintain preventive behaviours, seek testing, treatment and care for HIV. This paper presents findings and recommendations of the Social Drivers Working Group of the aids2031 initiative, which focus on how to ensure that efforts to address the root causes of HIV vulnerability are integrated into AIDS responses at the national level. Specific guidance is given on how to operationalise a structural approach. PMID:21970296

    This qualitative study explored knowledge, attitudes, beliefs and perceptions of sexual and reproductive health, focusing specifically on contraceptive use and HIV prevention among young unmarried men and women, 17-21 years, in urban Karachi, Pakistan. The main theme, identified as underlying meaning in the focus group discussions was "Societal norms and perceptions create barriers to knowledge and awareness about sexual and reproductive health matters among young adults". A knowledge gap was revealed concerning HIV/AIDS and contraceptive use among young males and females, who have to rely on media and peers for information seeking. Study participants perceived that HIV/AIDS is incurable and carries a social stigma. It was further revealed, that there is an opposition towards contraceptive use from religious leaders. Young adults in Pakistan are in need of improved knowledge about HIV/AIDS and contraceptive use. Youth clinics and schools/colleges may play a significant role in this regard. The religious leaders need to be informed about the beneficial effects of contraceptives and they should be part of any family planning/contraceptive use program to ensure better community acceptance. At the structural level there is an urgent need for policies targeting the issue of sexual and reproductive health, particularly HIV/AIDS information and contraceptive use to target the young population. The health care services should be able to respond by offering relevant services. PMID:23985107
