A qualitative analysis of factors influencing the implementation of antiretroviral treatment adherence policy in Ghana: stakeholders perspective.

BACKGROUND: The Joint United Nations Programme on HIV/AIDS launched the 90-90-90 initiative. Failure to meet the target reflects the difficulties in successfully implementing HIV treatment policy. There are research gaps in exploring personal and external factors influencing HIV treatment in Ghana. To fill this gap, we explored individual and environmental (interpersonal, community and structural) factors influencing stakeholders' HIV treatment policy implementation in Ghana. METHODS: Fifteen qualitative semi-structured in-depth interviews were conducted among representatives in different management positions at hospitals, health directorates, the Ghana AIDS Commission, the National AIDS and STI control program, and the National Association of People Living with HIV. RESULTS: Using thematic analysis, the findings suggest that individual and environmental factors such as attitude towards policy, awareness of HIV treatment policy, training received on policy implementation, difficulties related to patient factors, alternate sources of HIV care, inefficient policy decision-making, monitoring and evaluation of HIV treatment policy, lack of HIV treatment policy implementation training, poor availability of logistics, policy and guidelines, infrastructure, organization of training, and staff availability may hinder successful HIV treatment policy implementation. CONCLUSION: Several individual and environmental (interpersonal, community and structural) factors seem to influence HIV treatment policy implementation. To ensure successful policy implementation stakeholders need to receive training on new policies, availability of sufficient supplies of material resources, inclusive decision-making, receive supportive monitoring of policy implementation, and oversight

The World Starts With Me: A multilevel evaluation of a comprehensive sex education programme targeting adolescents in Uganda

<p>Abstract</p> <p>Background</p> <p>This paper evaluates the effect of the World Starts With Me (WSWM), a comprehensive sex education programme in secondary schools in Uganda. The aim of the present study was to assess the effects of WSWM on socio-cognitive determinants of safe sex behaviour (delay; condom use and non-coercive sex).</p> <p>Methods</p> <p>A survey was conducted both before and immediately after the intervention among students in intervention (<it>N </it>= 853) and comparison (<it>N </it>= 1011) groups. A mixed model repeated measures analysis was performed to assess the effectiveness of the WSWM programme on the main socio-cognitive determinants of safe sex behaviour at post-test. A similar post-hoc comparison was made between schools based on completeness and fidelity of implementation of WSWM.</p> <p>Results</p> <p>Significant positive effects of WSMW were found on beliefs regarding what could or could not prevent pregnancy, the perceived social norm towards delaying sexual intercourse, and the intention to delay sexual intercourse. Furthermore, significant positive effects of WSWM were found on attitudes, self-efficacy and intention towards condom use and on self-efficacy in dealing with sexual violence (pressure and force for unwanted sex). A reversed effect of intervention was found on knowledge scores relating to non-causes of HIV (petting, fondling and deep kissing). A follow-up comparison between intervention schools based on completeness of the programme implementation revealed that almost all significant positive effects disappeared for those schools that only implemented up to 7 out of 14 lessons. Another follow-up analysis on the basis of implementation fidelity showed that schools with a "partial" fidelity score yielded more significant positive effects than schools with a "full" fidelity of implementation score.</p> <p>Conclusions</p> <p>The study showed an intervention effect on a number of socio-cognitive determinants. However, the effectiveness of WSWM could be improved by giving more systematic attention to the context in which such a programme is to be implemented. Implications for the systematic development and implementation of school-based safe sex interventions in Uganda will be discussed.</p

Liver Progenitor Cell Line HepaRG Differentiated in a Bioartificial Liver Effectively Supplies Liver Support to Rats with Acute Liver Failure

A major roadblock to the application of bioartificial livers is the need for a human liver cell line that displays a high and broad level of hepatic functionality. The human bipotent liver progenitor cell line HepaRG is a promising candidate in this respect, for its potential to differentiate into hepatocytes and bile duct cells. Metabolism and synthesis of HepaRG monolayer cultures is relatively high and their drug metabolism can be enhanced upon treatment with 2% dimethyl sulfoxide (DMSO). However, their potential for bioartificial liver application has not been assessed so far. Therefore, HepaRG cells were cultured in the Academic Medical Center bioartificial liver (AMC-BAL) with and without DMSO and assessed for their hepatic functionality in vitro and in a rat model of acute liver failure. HepaRG-AMC-BALs cultured without DMSO eliminated ammonia and lactate, and produced apolipoprotein A-1 at rates comparable to freshly isolated hepatocytes. Cytochrome P450 3A4 transcript levels and activity were high with 88% and 37%, respectively, of the level of hepatocytes. DMSO treatment of HepaRG-AMC-BALs reduced the cell population and the abovementioned functions drastically. Therefore, solely HepaRG-AMC-BALs cultured without DMSO were tested for efficacy in rats with acute liver failure (n = 6). HepaRG-AMC-BAL treatment increased survival time of acute liver failure rats ∼50% compared to acellular-BAL treatment. Moreover, HepaRG-AMC-BAL treatment decreased the progression of hepatic encephalopathy, kidney failure, and ammonia accumulation. These results demonstrate that the HepaRG-AMC-BAL is a promising bioartificial liver for clinical application

Towards optimal effectiveness of tobacco packaging communications: Determinants and beliefs predicting smoking initiation and cessation

Background: Although threatening health communications have been found to be ineffective or even backfire, they remain popular. Identifying alternatives to warning labels on tobacco packaging requires first identifying the determinants and beliefs that predict whether people start to smoke or successfully quit. The current literature synthesis provides this starting point for developing effective tobacco packaging communications. Methods: A query was entered into PsycINFO and MedLine. Hits were screened by two independent screeners in two rounds, and 114 hits were retained for extraction. Qualitative and quantitative results were extracted and integrated qualitatively or, where appropriate, meta-analysed with the R metafor package using random-effects models. Findings: Quantitatively, in addition to risk perception, a number of other predictors emerged, including self-efficacy, attitude, and subjective norm. In addition to quantitative evidence, a large number of beliefs that potentially predict smoking initiation and cessation were identified. Discussion: On the basis of the identified determinants and beliefs, tentative recommendations are made regarding specific theory- and evidence based communications on tobacco packaging. In addition, a list of beliefs requiring quantitative verification is presented to guide future research

Determinants of HPV vaccination intentions among Dutch girls and their mothers: a cross-sectional study

Abstract Background The Dutch government recently added universal Human Papilloma Virus (HPV) vaccination for 12-year-old girls to the existing national immunization program. The participation rate for the initial catch-up campaign for girls aged 13 to 16 years in 2009 was lower (47%) than expected (70%). To inform future HPV information campaigns, this paper examines the social and psychological determinants of the HPV vaccination intentions of girls aged 13 to 16 years and their mothers who were targeted by the Dutch catch-up campaign of 2009. Methods A random sample of girls and their mothers was chosen from the Dutch vaccination register and received a letter inviting them to participate (n = 5,998 mothers and daughters). In addition, a random sample was recruited via an online panel by a marketing research company (n = 650 mothers; n = 350 daughters). Both groups were asked to complete a web-based questionnaire with questions on social demographic characteristics, social-psychological factors and HPV vaccination intention. Backward linear regression analyses were conducted to examine which social-psychological factors were most dominantly associated with vaccination intention. Results Data from 952 mothers (14%) and 642 daughters (10%) were available for the intended analyses. The contribution of social demographic variables to the explained variance of HPV vaccination intention was small but significant for mothers (ΔR2 = .01; p = .007), but not significant for daughters (ΔR2 = .02; p = .17) after controlling for HPV vaccination uptake and the sample. In addition, social-psychological determinants largely contributed to the explained variance of HPV vaccination intention of mothers (ΔR2 = .35; p 2 = .34; p Conclusions Because of the large contribution of social-psychological variables to the explained variance of HPV vaccination intentions among the mothers and daughters, future communication strategies targeting HPV vaccination uptake should address attitudes, beliefs, subjective norms and habit strength. There is a need for longitudinal research to confirm the causality of the association between these determinants and HPV vaccination behavior indicated by this study.</p
