Intersectionality of HIV stigma and masculinity in eastern Uganda:implications for involving men in HIV programmes
Background Stigma is a determinant of social and health inequalities. In addition, some notions of masculinity can disadvantage men in terms of health outcomes. However, few studies have explored the extent to which these two axes of social inequality intersect to influence men's health outcomes. This paper investigates the intersection of HIV stigma and masculinity, and its perceived impact on men's participation in and utilisation of HIV services in Uganda. Methods Interviews and focus group discussions were conducted in Mbale and Jinja districts of Uganda between June and October 2010. Participants were men and women living with HIV (n = 40), their family members (n = 10) and health providers (n = 15). Inductive analysis was used to identify mechanisms through which stigma and masculinity were linked. Results Our findings showed that HIV stigma and masculinity did not exist as isolated variables, but as intersecting phenomena that influenced men's participation in HIV services. Specifically, HIV stigma threatened masculine notions of respectability, independence and emotional control, while it amplified men's risk-taking. As a result, the intersection of masculinity and HIV stigma prevented some men from i) seeking health care and accepting a 'sick role'; ii) fulfilling their economic family responsibilities; iii) safeguarding their reputation and respectability; iv) disclosing their HIV status; and v) participating in peer support groups. Participation in some peer support activities was considered a female trait and it also exacerbated HIV stigma as it implicitly singled out those with HIV. In contrast, inclusion of income-generating activities in peer support groups encouraged men's involvement as it enabled them to provide for their families, cushioned them from HIV stigma, and in the process, provided them with an opportunity to redeem their reputation and respectability. Conclusion To improve men's involvement in HIV services, the intersection between HIV stigma and masculinity should be considered. In particular, better integration of and linkage between gender transformative interventions that support men to reconstruct their male identities and reject signifiers of masculinity that prevent their access to HIV services, and stigma-reduction interventions that target social and structural drivers of stigma is required within HIV programmes
Responding to adolescents living with HIV in Zambia:a socialâecological approach
The number of adolescents living with HIV in Zambia is increasing, yet little is known about their experiences in a social context. Such knowledge could enable HIV programs to better respond to their needs. This qualitative study examined the experiences of adolescents living with HIV in Kitwe, Kalomo and Lusaka in Zambia. In- depth interviews were conducted with adolescents aged 10â19 living with HIV (n = 58) and their health care providers (n = 14). In addition, 13 focus group sessions were conducted with adolescents living with HIV (n = 53), health care providers (n = 24) and parents (n = 21). Thematic analysis was used to draw out the socialâecological determinants of adolescents' experiences. Results showed that a range of factors located at the individual, family and peer, community and structural levels determine the experiences of adolescents living with HIV. At the individual level, resilience and internalized stigma were found to shape adolescents' perception of an HIV diagnosis, and their ability to maintain a positive outlook and sustain relationships. Family and peers supported adolescents to adjust to new drug-taking routines, but these people occasionally disclosed adoles- cents' HIV status inappropriately. At the community level, stigma and discrimination in schools were found to negatively influence adolescents' experiences, suggesting that approaches to normalize HIV in schools are need- ed. The presence of non-governmental organizations provided an entry point for the provision of broad-based livelihood, nutritional and psychosocial services for adolescents living with HIV at the community level. At the structural level, poor flexibility of clinic opening hours, staff shortages and a lack of health policies related to adolescents living with HIV presented ongoing limitations to adolescents' ability to access relevant services. In conclusion, adolescents' experiences of living with HIV are influenced by factors located within and beyond adolescents themselves. Understanding these contextual factors, and adopting interventions that accentuate positive experiences while mitigating negative ones, could strengthen the provision of services tailored to the needs and circumstances of adolescents living with HIV in Zambia
Developing a conformance methodology for clinically-defined medical record headings:a preliminary report.
Background: The Professional Records Standards Body for health and social care (PRSB) was formed in 2013 to develop and assure professional standards for the content and structure of patient records across all care disciplines in the UK. Although the PRSB work is aimed at Electronic Health Record (EHR) adoption and interoperability to support continuity of care, the current technical guidance is limited and ambiguous.
Objectives: This project was initiated as a proof-ofconcept to demonstrate whether, and if so, how, conformance methods can be developed based on the professional standards. Methods: An expert group was convened, comprising clinical and technical representatives. A constrained data set was defined for an outpatient letter, using the subset of outpatient headings that are also present in the ep-SOS patient summary. A mind map was produced for the main sections and sub-sections. An openEHR archetype model was produced as the basis for creating HL7 and IHE implementation artefacts.
Results: Several issues about data definition and representation were identified when attempting to map the outpatient headings to the epSOS patient summary, partly due to the difference between process and static viewpoints. Mind maps have been a simple and helpful way to visualize the logical information model and expose and resolve disagreements about which headings are purely for human navigation and which, if any, have intrinsic meaning.
Conclusions: Conformance testing is feasible but nontrivial. In contrast to traditional standards-development timescales, PRSB needs an agile standards development process with EHR vendor and integrator collaboration to ensure implementability and widespread adoption. This will require significant clinical and technical resources
Performance of ChatGPT on USMLE: Unlocking the Potential of Large Language Models for AI-Assisted Medical Education
Artificial intelligence is gaining traction in more ways than ever before.
The popularity of language models and AI-based businesses has soared since
ChatGPT was made available to the general public via OpenAI. It is becoming
increasingly common for people to use ChatGPT both professionally and
personally. Considering the widespread use of ChatGPT and the reliance people
place on it, this study determined how reliable ChatGPT can be for answering
complex medical and clinical questions. Harvard University gross anatomy along
with the United States Medical Licensing Examination (USMLE) questionnaire were
used to accomplish the objective. The paper evaluated the obtained results
using a 2-way ANOVA and posthoc analysis. Both showed systematic covariation
between format and prompt. Furthermore, the physician adjudicators
independently rated the outcome's accuracy, concordance, and insight. As a
result of the analysis, ChatGPT-generated answers were found to be more
context-oriented and represented a better model for deductive reasoning than
regular Google search results. Furthermore, ChatGPT obtained 58.8% on logical
questions and 60% on ethical questions. This means that the ChatGPT is
approaching the passing range for logical questions and has crossed the
threshold for ethical questions. The paper believes ChatGPT and other language
learning models can be invaluable tools for e-learners; however, the study
suggests that there is still room to improve their accuracy. In order to
improve ChatGPT's performance in the future, further research is needed to
better understand how it can answer different types of questions.Comment: 12 pages, 4 Figues, 4 table
Community and service provider views to inform the 2013 WHO consolidated antiretroviral guidelines:key findings and lessons learnt
Objective:The objective was to evaluate community and healthcare worker (HCW) values and preferences on key topics to inform the development of the 2013 WHO consolidated guidelines for antiretroviral therapy in low and middle income countries. Design:Cross-sectional e-survey and e-forum discussion; focus group discussions (FGDs) Methods:Data were collected on community perspectives regarding a range of potential clinical and operational recommendations in the 2013 guidelines between November 2012 and January 2013 through an e-survey (nâ=â1088) and e-forum (nâ=â955). Additional FGDs were held with people living with HIV (PLHIV) in Malawi and Uganda (nâ=â88) on antiretroviral therapy (ART) use among pregnant women. Two surveys were also undertaken on similar topics covered in the e-survey for health care workers caring for adults (nâ=â98) and children (nâ=â348). Results:There were 1088 e-survey respondents from 117 countries: of whom 37.7% (298/791) were females, 49.9% (431/864) PLHIV, and 20.9% (174/831) from low-income countries. The proportion of e-survey respondents who supported raising the CD4 T-cell threshold for ART initiation in adults from 350 to 500âcells/ÎŒl was 51.0% (355/696), and regardless of CD4 T-cell count for all pregnant females 89.8% (607/676), HIV serodiscordant partners 71.9% (486/676), and all children on diagnosis of infection 47.4% (212/447). E-survey respondents strongly supported discontinuing use of stavudine (72.7%, 416/572), task-shifting/sharing from doctors to nurses (75.2%, 275/365) and from nurses to community health workers (71.1%, 261/367) as strategies to expand access to HIV testing, care, and treatment. Focus group discussion respondents identified service capacity, and social and legal concerns as key considerations influencing the decisions of women living with HIV to continue ART after the risk of vertical transmission has passed. Key lessons learnt in these consultations included the need for piloting and validation of questions; sufficient time to adequately disseminate the survey; and consideration of using FGDs and mobile phone technology to improve participation of people with limited internet access. Conclusion:Community participation in guideline development processes is important to ensure that their perspectives are considered in the resulting recommendations. Communities should be actively involved in the adaptation, implementation, and accountability processes related to the guidelines
Molecular Basis of Plant Adaptation against Aridity
Environment fluctuations have become the greatest threat to global food security. Of various abiotic stress factors, aridity hampers the most yield contributing attributes. In the context of agriculture, term âaridityâ refers to a protracted period of insufficient precipitation, having detrimental influence on crop development and overall biological output. A sustained drought has considerable negative effects on crops and livestock, including the reduced production, destruction of property, and livestock sell-offs. Consequently, plants themself exert various kinds of defensive mechanisms to combat the ill effects of climate change. For example, plants with small leaves, benefit from aridity as part of their strategy for modifying the soil to water shortages and nutrient restrictions. Furthermore, low genetic diversity among significant crop species, together with ecological productivity limits, must be addressed in order to adapt crops to episodic drought spells in the coming days. A deeper understanding of the molecular and genetic underpinnings of the most important intrinsic adaptation responses to drought stress seems to be beneficial for gene engineering as well as gene-based expression investigations in plant systems under hostile environment. Recently, molecular markers and âomicsâ have opened a huge opportunity to identify and develop specific gene constructs governing plant adaptation to environmental stress
Retention and mortality outcomes from a community-supported publicâprivate HIV treatment programme in Myanmar
Introduction: There is a growing interest in the potential contribution the private sector can make towards increasing access to antiretroviral therapy (ART) in low- and middle-income settings. This article describes a publicâprivate partnership that was developed to expand HIV care capacity in Yangon, Myanmar. The partnership was between private sector general practitioners (GPs) and a community-based non-governmental organization (International HIV/AIDS Alliance). Methods: Retrospective analysis of 2119 patient records dating from March 2009 to April 2015 was conducted. Outcomes assessed were immunological response, loss to follow-up, all-cause mortality, and alive and retained in care. Follow-up time was calculated from the date of registration to the date of death, loss to follow-up, transfer out, or if still alive and known to be in care, until April 2015. Cox proportional hazards model was used to identify predictors of loss to follow-up and mortality. KaplanâMeier survival analysis was used to estimate survival function of being alive and retained in care. Results: The median number of patients for each of the 16 GPs was 42 (interquartile range (IQR): 25â227), and the median follow-up period was 13 months. The median patient age was 35 years (IQR: 30â41); 56.6% were men, 62 and 11.8% were in WHO Stage III and Stage IV at registration, respectively; median CD4 count at registration was 177 cells/mm3; and 90.7% were on ART in April 2015. The median CD4 count at registration increased from 122 cells/mm3 in 2009 to 194 cells/mm3 in 2014. Among patients on ART, CD4 counts increased from a median of 187 cells/mm3 at registration to 436 cells/mm3 at 36 months. The median time to initiation of ART among eligible patients was 29 days, with 93.8% of eligible patients being initiated on ART within 90 days. Overall, 3.3% patients were lost to follow-up, 4.2% transferred out to other health facilities, and 8.3% died during the follow-up period. Crude mortality rate was 48.6/1000 person-years; 42% (n=74) of deaths occurred during the pre-ART period and 39.8% (n=70) occurred during the first six months of ART. Of those who died during the pre-ART period, 94.5% were eligible for ART. In multivariate regression, baseline CD4 count and ART status were independent predictors of mortality, whereas ART status, younger age and patient volumes per provider were predictors of loss to follow-up. Probability of being alive and retained in care at six months was 96.8% among those on ART, 38.5% among pre-ART but eligible patients, and 20.0% among ART-ineligible patients. Conclusions: Effectively supported private sector GPs successfully administered and monitored ART in Myanmar, suggesting that community-supported private sector partnerships can contribute to expansion of HIV treatment and care capacity. To further improve patient outcomes, early testing and initiation of ART, combined with close clinical monitoring and support during the initial periods of enrolling in treatment and care, are required
Association of acute toxic encephalopathy with litchi consumption in an outbreak in Muzaffarpur, India, 2014: a case-control study
Background Outbreaks of unexplained illness frequently remain under-investigated. In India, outbreaks of an acute
neurological illness with high mortality among children occur annually in Muzaffarpur, the countryâs largest litchi
cultivation region. In 2014, we aimed to investigate the cause and risk factors for this illness.
Methods In this hospital-based surveillance and nested age-matched case-control study, we did laboratory
investigations to assess potential infectious and non-infectious causes of this acute neurological illness. Cases were
children aged 15 years or younger who were admitted to two hospitals in Muzaffarpur with new-onset seizures or
altered sensorium. Age-matched controls were residents of Muzaffarpur who were admitted to the same two hospitals
for a non-neurologic illness within seven days of the date of admission of the case. Clinical specimens (blood,
cerebrospinal fluid, and urine) and environmental specimens (litchis) were tested for evidence of infectious
pathogens, pesticides, toxic metals, and other non-infectious causes, including presence of hypoglycin A or
methylenecyclopropylglycine (MCPG), naturally-occurring fruit-based toxins that cause hypoglycaemia and metabolic
derangement. Matched and unmatched (controlling for age) bivariate analyses were done and risk factors for illness
were expressed as matched odds ratios and odds ratios (unmatched analyses).
Findings Between May 26, and July 17, 2014, 390 patients meeting the case definition were admitted to the two referral
hospitals in Muzaffarpur, of whom 122 (31%) died. On admission, 204 (62%) of 327 had blood glucose concentration
of 70 mg/dL or less. 104 cases were compared with 104 age-matched hospital controls. Litchi consumption (matched
odds ratio [mOR] 9·6 [95% CI 3·6 â 24]) and absence of an evening meal (2·2 [1·2â4·3]) in the 24 h preceding illness
onset were associated with illness. The absence of an evening meal significantly modified the effect of eating litchis
on illness (odds ratio [OR] 7·8 [95% CI 3·3â18·8], without evening meal; OR 3·6 [1·1â11·1] with an evening meal).
Tests for infectious agents and pesticides were negative. Metabolites of hypoglycin A, MCPG, or both were detected in
48 [66%] of 73 urine specimens from case-patients and none from 15 controls; 72 (90%) of 80 case-patient specimens
had abnormal plasma acylcarnitine profiles, consistent with severe disruption of fatty acid metabolism. In 36 litchi
arils tested from Muzaffarpur, hypoglycin A concentrations ranged from 12·4 Όg/g to 152·0 Όg/g and MCPG ranged
from 44·9 Όg/g to 220·0 Όg/g.
Interpretation Our investigation suggests an outbreak of acute encephalopathy in Muzaffarpur associated with both
hypoglycin A and MCPG toxicity. To prevent illness and reduce mortality in the region, we recommended minimising
litchi consumption, ensuring receipt of an evening meal and implementing rapid glucose correction for suspected
illness. A comprehensive investigative approach in Muzaffarpur led to timely public health recommendations,
underscoring the importance of using systematic methods in other unexplained illness outbreaks
