Background: Globally, HIV viral load suppression rate, which is an indirect measure of the efficacy of antiretroviral (ART) medication, is 47% and 52% in Africa. In Cameroon, the viral load (VL) suppression rate is 44.7% and poor adherence is widely documented as being responsible for the large gap in VL Suppression. Enhanced adherence counselling (EAC) sessions, and enrolment and participation in support groups are specific interventions to improve ART adherence and improve viral load suppression. Purpose: This study assesses the uptake and contribution of support groups and EAC sessions in the management of adolescents with unsuppressed VL results at Centre Hospitalier d’Essos, Yaounde. Methods: A retrospective correlational quantitative patient files review was conducted for 138 files of HIV positive adolescents aged between 10 - 19 years with HIV VL above 1000 copies/ml enrolled in care between January 2009 and December 2019. Data from the questionnaire was entered into CSPRO version 7.4. and analyzed by using SPSS version 25.0. Results: A total of 138 participants (75 females and 63 males) with a mean age of 15 ± 3 years were included in our study. Sixty-nine (50%) participants were in World Health Organization (WHO) stage I;32.6% were in Stage II;13.0% and 4.3% were in stages III and IV, respectively. Thirty (21.7%) had a history of tuberculosis and 76% of the adolescents were being cared for primarily by their parents. The charts of the adolescents revealed that there was an association between completion of EAC sessions in adolescents with unsuppressed VL and eventual VL suppression (R.R = 2.5;CI 0.848 - 6.162;p = 0.033). However, there was no significant association between support group enrolment and active participation, and eventual VL Suppression. Furthermore, combining EAC and support group interventions was strongly associated with eventual VL Suppression in this group of initially unsuppressed adolescents (R.R = 7.5;C.I 2.544 - 22.360;p Conclusion: Suppression rates were good after completion of EAC sessions and participation in support group enrolment for adolescents with a high VL. As we move towards having 95% of ART-treated adolescents achieve and maintain viral suppression, there is a need to reinforce EAC sessions and support group enrolment in ART clinics targeting this priority group. 展开更多

Only about 25% of babies are exclusively breast fed until six months of age in developing countries though they are at a greater risk of infection and infant mortality. The Global Strategy for Maternal, Infant and Young Child Feeding (MI- YCF) Strategy developed by WHO/UNICEF in 2002 was to revitalize world attention to the impact of feeding practices on the nutritional status, growth, development, health and survival of infants and children. The data for this case study was collected through key informant interviews, observations and review of Save the Children nutrition programme reports and surveys. This information was then organized to produce a detailed description of the maternal, infant and young child nutrition programme in Habaswein and Wajir South districts or sub-counties. The maternal and infant young child nutrition (MIYCN) programme was launched in Habaswein and Wajir South districts in January 2012. The MIYCN programme followed recommendations of a Knowledge, Practice and Coverage (KPC) survey report in July 2012. To date, the programme has formed 48 Mother-to-mother Support Groups (MTMSGs), which are actively promoting the uptake of the recommended MIYCN practices in the community. MIYCN indicators have been markedly improved between July 2011 and February 2013 when surveys were conducted. The uptake of kitchen gardening has picked up significantly at Meri site and some mothers now have a changed attitude towards unskilled home deliveries and are conducting referrals for skilled births. The marked improvements in the performance of MIYCN indicators between July 2011 and February 2013 inWajir South and Habaswein districts can be partly attributed to the MIYCN programme established in January 2012. However, a randomized community trial is still required to provide conclusive results on the impact of care support groups on maternal, infant and young child feeding in this region. 展开更多

Background: Mutual Support Groups (MSG) provides to the patient, the ability to effective self-management behaviors, such as taking prescribed medications, following diet and exercise regimens, self-monitoring, and coping emotionally with the rigors of living with diabetes. Physicians, nurses and health promoters from public primary Health Care Centers (HCC) are responsible for providing follow-up care through MSGs. However, although the MSG program has been carried out, in the last decade Mexico presents the most alarming statistics in the prevalence and complications of Diabetes Mellitus type II (DM-II), suggesting a low impact of MSG in the strategy to support the effective control of the disease. Objetive: The aim of this work was to assess whether knowledge or benefits of effective management to control of DM-II, also to identify strengths and limitations of MSGs, in six different Health Care Centers (HCC), in San Luis Potosi, Mexico. This research provides an overview of patients’ perception, and significant issues that demand to adjust MGSs strategies, with the goal of exceed the expectations of current health statistics. Methods: A qualitative evaluation was carried out, with an ethnographic approach design. The study included 28 diabetic persons, (21 women and 7 men from ruraland urban carecenters). Semi-structured interviews, non-participant observation, and structured content analysis were used. Results: Support groups give patients a way to address emotional issues, and learn about their disease and self-care, although some patients consider participation an inconvenient obligation. Support group users mention barriers such as lack of continuity in support group activities, inconvenient meeting times, and the difficulty of commuting to attend group sessions. They also mention that overworked health care workers find it difficult to provide leadership to keep the group going. These issues have multiple implications for the success of strategies to control the disease. Conclusions: This study shows the need to apply a participatory model to disease support group strategies to reorganize their actions in such a way as to meet the needs and requirements of patients and to ensure their participation and help them control their disease. 展开更多

Health care facilities providing antiretroviral treatment (ART) to HIV positive people have seen a decline in the uptake and use of HIV support groups. A cross sectional survey was conducted to 1) determine the characteristics of HIV positive people who have and who have not attended support groups;2) determine factors associated with attendance of support groups;and 3) investigate perceived barriers to participate in support groups among HIV positive adults attending an ART clinic in Gauteng, South Africa. The total samples included 248 HIV positive adults and the highest proportion were females (n = 156, 62.9%). The mean age of the participants was 34.2 years, (range 18 to 56 years). Almost two thirds (n = 144, 58.1%) had never attended support groups. Participants who attended support groups were more likely to be older than non-attenders (OR = 1.04, CI: 1.01 - 1.07), more likely to be taking ART medication (OR = 1.64, CI: 1.00 - 2.65) and more likely to have known of their HIV diagnosis for a longer time (OR = 2.20, CI: 1.42 - 3.40). Employed participants were less likely to attend support groups than unemployed participants (OR = 0.47, CI: 0.27 - 0.80). Concerns for privacy and confidentiality in support groups, and fear of stigma and discrimination were the key barriers to participate in support groups. Participants also perceived support groups as a service for people who could not cope with their HIV diagnosis. Health care providers who plan to start support groups should take into consideration issues of support group size, confidentiality, and timing for support group meetings. It is imperative that education on the benefits of HIV support groups forms a primary component of routine counselling for PLWHI. 展开更多

Advances in antiretroviral therapy for both Human Immunodeficiency Virus (HIV) treatment and prevention have increased interest in adherence to HIV treatment. This is because the individual patient and public health benefits of antiretroviral treatment?(ART) greatly depend on the extent to which people living with HIV (PLHIV) adhere to the prescribed daily dosing regimens. Studies have shown that nonadherence to ART increases drug resistance, morbidity and person-to-person HIV transmission. Public health experts are trying different innovations to enhance ART adherence, including promoting support groups of PLHIV. The purpose of this study was to determine the value of support group participation in enhancing ART adherence. The study used a cross-sectional design to compare ART adherence among PLHIV who participate in support group activities and those who do not. Respondents were adults who were initiated on ART between January 1, 2010 and December 31, 2012. Multistage probability sampling was used to select study sites and respondents. Data was collected using a self-administered questionnaire from 1676 respondents between February and May 2014. Data was analyzed using STATA. Univariate analysis was carried out to generate descriptive statistics, while Chi-square tests were used to examine if there was an association between participation in support group activities and antiretroviral treatment adherence. ART adherence was self-reported by 745/788 (95%) and 814/888 (92%) respondents who had ever and had never participated in support group activities respectively. Among respondents who reported nonadherence to ART, 74/117 (8%) had never participated in support group activities compared to just 43/117 (5%) who participated in support group activities. These findings suggest that PLHIV who participate in support group activities are more likely to adhere to ART than those who do not participate. This implies that there is value in participating in support groups by PLHIV in terms of ART adherence. 展开更多

Value Management (VM) is a rigorous and systematic approach to improve the value and optimise the overall cost of a facility. It identifies opportunities to remove unnecessary costs while assuring that quality, reliability, performance, and other critical factors will meet or exceed the customers’ expectations. It has been widely used in the construction industry in a number of countries. A recent survey, however, revealed several problems that hinder the wider use of this methodology in the industry. To overcome these problems, a feasibility study has been conducted to investigate whether or not a Group Support System (GSS) can support collaborative works in VM workshops. This paper introduces the development and structure of a prototype GSS which is designed to support the collaborative works of stakeholders in VM workshops. It begins with an introduction to the conceptual GSS framework and job plan, illustrating what GSS supports can be provided to VM workshops. This is followed by a detailed description of the GSS prototype system to demonstrate how these supports can be performed as an integrated computer system. The testing of the system is also discussed. The research findings provide strong evidence in supporting the notion of using GSS to improve VM implementation. The information support of GSS has been ranked to be the most useful GSS functions and most of the practitioners interviewed are highly interested in applying GSS to support VM workshops in the future. 展开更多

Mutual support groups are increasingly implemented in higher education settings across high-income countries to promote peer-based support,with demonstrated benefits for emotional well-being and social connectedness.However,their impact on other domains of students'lives remains underexplored,particularly in low-and middle-income contexts.This study investigates the outcomes of mutual support groups by examining students'perceived changes in mental well-being,academic skills,career certainty,social support attitudes,interpersonal functioning,and attitudes toward seeking psychological help.Using a qualitative retrospective approach,open-ended responses were collected from 20 Kosovar students(aged 18-25 years)at a major public university after a 5-week support group program.Data were thematically analyzed using a deductive approach based on predefined themes aligned with the study's objectives.Findings revealed that participating in mutual support groups contributed to reduced stress,lower anxiety,and improved mood,as students felt heard and emotionally supported by peers facing similar challenges.Students adopted more effective study habits and time management techniques through the sharing of practical strategies and encouragement.Open discussions about career uncertainty fostered clarity and confidence in students'academic and professional goals.Hearing from the perspectives of others on mental health reduced internalized stigma and increased willingness to seek psychological support.The group setting also enabled students to develop stronger interpersonal skills,including empathy,emotional expression,and a sense of connection and belonging.This study highlights the potential of mutual support groups as effective peer-led supplements in higher education by emphasizing improvements in student well-being,academic development,and mental health attitudes. 展开更多
