Existing research focuses on projections of OVC numbers, interventions, outcomes and descriptions of care arrangements. A lot of information exists on their poor sexual and reproductive health (SRH) status—most of it quantitative. The purpose of this paper is to present the voice and perceptions of OVC in regards to their SRH. Methods: This was a mixed-methods qualitative study drawing from phenomenology and it used purposive sampling to recruit 129 participants. Results: OVC perceptions and priorities do not always intersect with those of professionals and this has implications for existing and planned interventions. For example some OVC think favorably about early marriages while others have mechanisms of self-protection again SRH harm although this is not usually acknowledged. Conclusions: OVC demonstrate agency;therefore positioning them at the heart of service planning and delivery is an effective strategy in increasing the uptake and impact of interventions seeking to address their sexual and reproductive health needs.展开更多

In the developing world, about 132 million people have lost one or both parents due to the AIDS pandemic and 25 million children have been orphaned by HIV/AIDS in 2010. The HIV prevalence in Cameroon is estimated at 5.1%. As of 2010, there were 304,000 deaths due to AIDS in Cameroon. Out of 1,200,000 orphans and vulnerable children in Cameroon in 2010, 300,000 were AIDS orphans. The HIV/AIDS burden impacts child survival, growth and development in the traditional African setting. With so many orphans in the population, along with many vulnerable children, strategies must be developed to respond more effectively to their critical needs. This study provides a model for OVC care and support in Cameroon. The model was developed out of extensive work using a participatory approach involving traditional, administrative and health stakeholders on OVC in Yaounde I and Yaounde VI Councils, Nanga Eboko Health District, Isangelle, Ekondo Titi, and Bafaka-Balue communities in Cameroon. Consultancy services with PLAN Cameroon, the Pan African Institute for Development-West Africa coupled with facilitation of many training workshops on OVC with Save the orphans Foundation, the Ministry of Social Affairs, and the Ministry of Public Health and working with the National AIDS Control Committee. The essential components of a holistic framework for the care of OVC have been identified. A public health model for the care of OVC and a mechanism for their identification and a referral system for testing OVC for HIV are proposed. Through this model, a mechanism for the effective holistic care of OVC and collaboration is enhanced.展开更多

This paper presents the achievements and implications of HIV Programme Development Project (HPDP) funded by World Bank on care and support services for OVC in Osun State, Nigeria. Eight Civil Society Organisations (CSOs) were engaged by Osun State Agency for the Control of AIDS (OSACA) as part of HPDP to provide care and support services for OVC between year 2013 and 2015. Using reporting tools, data collected by the CSOs were entered into District Health Information System 2 (DHIS2) platform and analysed using Microsoft Excel. In addition, Key Informant Interviews (KII) were conducted among the selected CSOs, OVC and the caregivers who were beneficiaries of HPDP in Osun State, Nigeria. A total of 12,353 OVC were reached and about half of them were female. There was an increase in the trends of number of OVC seen and the support services provided from the year 2013 to 2015. Of the 12,353 OVC that benefitted from this programme, 1905 (15.4%) received health care services, 5383 (43.6%) received nutritional services, 5317 (43.0%) received educational services and 9861 (79.8%) were provided with psychosocial support services. About 503 (4.1%) of the OVC received economic strengthening services while 270 (2.2%) of household heads were provided with economic support. However, 3 OVC were lost to follow-up, 14 OVC voluntarily withdrew from the project and 6 OVC died. The FGD and KII revealed that the project was very impactful in transforming the lives of the OVC. Programmes for children orphaned and made vulnerable by HIV/AIDS will contribute to the achievement of HIV/ AIDS prevention and control efforts. The HIV/AIDS free generation can be built by responding to the physical, social and mental needs of these children and their families in their communities. There is a need to scale-up this programme.展开更多

The number of the orphans is drastically increasing because of the violence crisis for a long time since 2004. The government has the policy to rehabilitate the orphans affected by the violence and takes the scholarships for relief their mind related injury Surveillance. The orphans trust the civil society more than the public government. Some opinions suggest the education, the activities, i.e., sports, music to empower the orphans, and the roles of the family and family members are the most important to take care and rehabilitate the orphans by using the religion for conducting ＂the social well-being＂.展开更多

The deregulation of Nur77 signalling often relates to various serious diseases, including cancer and non-cancer diseases. A systematic review is necessary for the better understanding of Nur77 in clinical treatment. In this article, we comprehensively conclude the lipid regulation function and expression of Nur77, and its role in COPD. Finally, we prospect that development of drugs and clinical biochemical investigations targeting of Nur77 has considerable potential within healthcare.展开更多

文摘Objectives:Gastric cancer(GC)is often associated with high invasiveness,epithelial-mesenchymal transition(EMT),and resistance to 5-fluorouracil(5-FU),highlighting the need for novel therapeutic targets.This study explored whether diallyl disulfide(DADS)upregulates retinoic acid-related orphan receptor alpha(RORα)to weaken the protein kinase C alpha(PKCα)/RORα-mediated RORα/β-catenin pathway,thereby inhibiting GC cell invasion,epithelial-mesenchymal transition(EMT),and enhancing 5-FU sensitivity.Methods:Human GC cell lines MGC-803 and SGC7901 were treated with DADS,RORαagonist SR1078/antagonist T0901317,and PKCαagonist TPA/antagonist GO6976.Cell proliferation(MTT),migration(scratch assay),invasion(Transwell),protein expression(Western blot),protein interactions(coimmunoprecipitation),and localization(immunofluorescence)were detected.Apoptosis and 5-FU sensitivity-related proteins were examined.Experiments were triplicated;statistics used t-test/ANOVA(p<0.05).Results:DADS/SR1078 inhibited GC cell proliferation/migration/invasion,upregulated RORα/E-cadherin,downregulated nuclearβ-catenin/TGF-β1/Rac1/Vimentin,and weakened EMT(reversed by T0901317).DADS/TPA upregulated RORα/p-RORα/PKCα/p-PKCα,promoted PKCα-RORαbinding,and downregulated RORα/β-catenin target genes(counteracted by GO6976).DADS upregulated caspase-3 and downregulated Bcl-2/P-gp/XIAP via RORα,promoting apoptosis and 5-FU sensitivity.Conclusion:DADS inhibits GC progression and enhances 5-FU sensitivity by PKCα/RORα-mediated downregulation of RORα/β-catenin signaling,paralleling SR1078/TPA effects.It may act as a novel RORαagonist for GC therapy.
