Debate remains about how to effectively obtain information from adolescents with disabilities in marginalized areas and how to apply this knowledge to shape rehabilitation activities. This study explored how to empower adolescents in the urban slums of North India to assume greater control over their rehabilitation within the context of a local community-based rehabilitation program. Participants included 21 adolescents with and 11 adolescents without disability (aged 12 to 18 years), and 10 community-based rehabilitation workers. A critical ethnographic approach was adopted. Fieldwork was conducted from January to May 2005 and October 2006 to March 2007. This paper focuses on the methodological aspects of this study, and how critical ethnography was used to inform positive changes for adolescents with disabilities using their perspectives.

Objective: For people living with HIV (PLHIV), strict adherence to highly active antiretroviral therapy (HAART) is the key to effective treatment and retention in human immunodeficiency virus (HIV) care. There are many factors which promote or halt the antiretroviral therapy (ART) adherence practices. Therefore, the present study aimed to examine the HAART adherence levels and to explore patients' views about barriers and facilitators to HIV treatment adherence. Methods: Semi-structured interviews were conducted among 15 PLHIV at the ART clinic of Dr. Ram Manohar Lohia Hospital, New Delhi. Interviews were audio-recorded in the local Hindi language, and bilingual experts (English and Hindi) transcribed verbatim. Qualitative data were coded for themes and subthemes and analyzed using a phenomenological approach as per thematic content analysis. Results: Feeling of hopelessness, delayed ART initiation, difficult initial phase of ART, forget to take ART on time, fear of disclosure of HIV diagnosis, lack of privacy and negative social support, and impact of lockdown due to COVID-19 were revealed as significant barriers to ART adherence. At the same time, commitment to raise and educate children, ART to increase life span, maintain oneself to be physically fit and healthy, only a single pill per day, very supportive counselors and health-care professionals, and hope to give birth to a healthy child were identified as facilitators of HIV retention. Conclusion: Understanding patient's perception about ART adherence, its motivational and barrier factors which are directly affecting ART adherence and retention of PLHIV in HIV treatment and follow-ups are of utmost importance to improve ART adherence during HIV patient care services.

Purpose: This study was conducted to review data gathered during a pilot project which trialed the use of a tablet computer, the iPad.Methods: Students from a segregated special education school and pre-vocational centre, with a wide range of intellectual and physical disabilities, were previously observed participating in 5–10-min introductory learning sessions with the iPad. This study reviewed quantitative and qualitative data collected during these sessions which included data regarding students’ level of engagement and overall ability to learn how to operate the iPad and its applications.Results: Results were positive for level of engagement and ease of use with cause and effect applications. For lower functioning students or students not previously exposed to tablet technology, scores were lower but overall remained high based on the 5-point scaling used in this study.Conclusion: Regular use of tablet technology in the classroom with applications appropriate to the level of ability of the student has the potential to enhance engagement in learning as well as maximise independence in the classroom.Implications for RehabilitationThe iPad has the capacity to be used with learners of all different ability levels if applications are selected appropriately and learners are given equal opportunity to access this type of technology.Enjoyment when using the iPad was high overall and this type of technology has the potential to promote more engagement in the learning process.Many applications are easy to use and progress students through step by step increasing the potential for independent learning in the classroom.

The successful navigation of malaria parasites through their life cycle, which alternates between vertebrate hosts and mosquito vectors, requires a complex interplay of metabolite synthesis and salvage pathways. Using the rodent parasite Plasmodium berghei, we have explored the synthesis and scavenging pathways for lipoic acid, a short-chain fatty acid derivative that regulates the activity of α-ketoacid dehydrogenases including pyruvate dehydrogenase. In Plasmodium, lipoic acid is either synthesized de novo in the apicoplast or is scavenged from the host into the mitochondrion. Our data show that sporozoites lacking the apicoplast lipoic acid protein ligase LipB are markedly attenuated in their infectivity for mice, and in vitro studies document a very late liver stage arrest shortly before the final phase of intra-hepaticparasite maturation. LipB-deficient asexual blood stage parasites show unimpaired rates of growth in normal in vitro or in vivo conditions. However, these parasites showed reduced growth in lipid-restricted conditions induced by treatment with the lipoic acid analogue 8-bromo-octanoate or with the lipid-reducing agent clofibrate. This finding has implications for understanding Plasmodium pathogenesis in malnourished children that bear the brunt of malarial disease. This study also highlights the potential of exploiting lipid metabolism pathways for the design of genetically attenuated sporozoite vaccines. [ABSTRACT FROM AUTHOR]

The toxic subcellular accumulation of lipids predisposes several human metabolic syndromes, including obesity, type 2 diabetes, and some forms of neurodegeneration. To identify pathways that prevent lipid-induced cell death, we performed a genome-wide fatty acid sensitivity screen in Saccharomyces cerevisiae. We identified 167 yeast mutants as sensitive to 0.5 mM palmitoleate, 45% of which define pathways that were conserved in humans. 63 lesions also impacted the status of the lipid droplet; however, this was not correlated to the degree of fatty acid sensitivity. The most liposensitive yeast strain arose due to deletion of the "ARE2 required for viability" (ARV1) gene, encoding an evolutionarily conserved, potential lipid transporter that localizes to the endoplasmic reticulum membrane. Down-regulation of mammalian ARV1 in MIN6 pancreatic β-cells or HEK293 cells resulted in decreased neutral lipid synthesis, increased fatty acid sensitivity, and lipoapoptosis. Conversely, elevated expression of human ARV1 in HEK293 cells or mouse liver significantly increased triglyceride mass and lipid droplet number. The ARV1-induced hepatic triglyceride accumulation was accompanied by up-regulation of DGAT1, a triglyceride synthesis gene, and the fatty acid transporter, CD36. Furthermore, ARV1 was identified as a transcriptional of the protein peroxisome proliferator-activated receptor α(PPARα), a key regulator of lipid homeostasis whose transcriptional targets include DGAT1 and CD36. These results implicate ARV1 as a protective factor in lipotoxic diseases due to modulation of fatty acid metabolism. In conclusion, a lipotoxicity-based genetic screen in a model microorganism has identified 75 human genes that may play key roles in neutral lipid metabolism and disease. [ABSTRACT FROM AUTHOR]
