Regional anthropometry changes in antiretroviral-naïve persons initiating a Zidovudine-containing regimen in Mbarara, Uganda

Lipodystrophy is commonly reported in Africa after antiretroviral therapy (ART) is initiated, but few studies have objectively measured changes in body composition. Body composition was determined in 76 HIV-infected participants from Mbarara, Uganda after starting a thymidine-analog regimen, and annual change was determined using repeated measures analysis. We measured skinfolds (tricep, thigh, subscapular, and abdomen), circumferences (arm, hip, thigh, waist), and total lean and fat mass (using bioelectric impedance analysis). A cross-sectional sample of 49 HIV-uninfected participants was studied for comparison. At baseline, most body composition measures were lower in HIV-infected than uninfected participants, but waist circumference was similar. After 12 months on ART, there was little difference in body composition measures between HIV-infected and uninfected participants; median waist circumference appeared higher in HIV-infected participants (79 vs. 75 cm; p = 0.090). Among HIV-infected participants, increases were observed in total lean and fat mass, circumference, and skinfold measures; only the increase in tricep skinfold did not reach statistical significance (+1.05 mm; 95% confidence interval: -0.24, 2.34; p = 0.11). Regional anthropometry in peripheral and central body sites increased over 12 months after ART initiation in HIV-infected persons from southwestern Uganda, suggesting a restoration to health. Gains in the tricep skinfold, a reliable marker of subcutaneous fat, appeared blunted, which could indicate an inhibitory effect of zidovudine on peripheral subcutaneous fat recovery.     

Psychiatric morbidity in mothers of children attending primary care facility in Ilorin, Nigeria: drawing attention to those affected concurrently with their children

Objective

To determine the prevalence of psychiatric morbidity among mothers of children attending a primary care clinic in University of Ilorin Teaching Hospital as precursor to developing an intervention programme.

Method

WThree hundred fifty mothers of children aged 7–14 years were screened with the 12-item General Health Questionnaire for psychiatric morbidity. As part of the larger study, their children were screened for psychiatric disorders with the parents’ version of the Child Behaviour Questionnaire, and a subsample of 157 mother/child dyad had second-stage interview with the children’s version of the Schedule for Affective Disorders and Schizophrenia to determine psychiatric morbidity in these children.

Results

Twenty-eight out of 350 mothers (8%) had probable psychiatric morbidity. Mothers with psychiatric morbidity were significantly more likely to have children with Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition psychiatric diagnosis (8 of 28, P=0.011), experience parenting difficulties with some of their children (13 of 28, P=0.000) and have poor husband support for the care of their children.

Conclusion

The presence of psychiatric morbidity in mothers may require that other members of the family especially the children be screened for psychiatric disorders particularly when there are parenting difficulties and poor spousal support; in this way primary prevention or control can effectively be carried out.     

Rehabilitation��Emerging Technologies, Innovative Therapies, and Future Objectives

Stroke is the leading cause of long-term disability. The goal of stroke rehabilitation is to improve recovery in the years after a stroke and to decrease long-term disability. This article, titled “Rehabilitation—Emerging Technologies, Innovative Therapies, and Future Objectives” gives evidence-based information on the type of rehabilitation approaches that are effective to improve functional mobility and to address cognitive impairments. We review the importance of taking a translational approach to neurorehabilitation, considering the interaction of motor and cognitive systems, skilled learned purposeful limb movement, and spatial navigation ability. Known biologic mechanisms of neurorecovery are targeted in relation to technology implemented by members of the multidisciplinary team. Results from proof-of-concept, within subjects, and randomized controlled trials are presented, and the implications for optimal stroke rehabilitation strategies are discussed. Developing clinical practices are highlighted and future research directions are proposed with goals to provide insight on what the next steps are for this burgeoning discipline.

Cytological and biochemical studies during the progression of alloxan-induced diabetes and possible protection of an aqueous leaf extract of Costus afer

Some plants have proven efficacy in the management of diabetes mellitus, of which Costus afer is one. This study was designed to evaluate the cytological and biochemical properties, and comparative ameliorating effects, of an aqueous extract of Costus afer Ker Gawl.（Costaceae） leaf and glibenclamide（GBM）, in liver, kidney, and pancreatic injury induced by alloxan. Thirty male albino rats were divided into six weight-matched groups. Group one served as the negative control（non-induced and non-treated, control）, while groups 2–6 were alloxan-induced diabetic groups. Group 2 served as a positive control（induced and non-treated, IC）, groups 3–5 were treated with different doses of the extract（375, 750, and 1 125 mg/kg body weight） and glibenclamide, respectively. Body weight, absolute and relative organ weights, food and fluid intake, levels of serum glucose and liver enzymes and kidney parameters were calculated and compared. Hepatocytes, renal tubules, and pancreatic cells of diabetic rats, in diabetic non-treated and treated rats were harvested and examined histopathologically. There was dose dependent amelioration on the injuries induced by alloxan on both hepatocytes, renal tubules, and pancreatic cells after treatment with Costus afer. The glucose level was reduced significantly in the Costus afer treated diabetic rats compared with the non-treated diabetic group. Costus afer leaves seem to be effective against diabetic cell injury induced in rat liver, kidney, and pancreas.     

The social context of food insecurity among persons living with HIV/AIDS in rural Uganda

HIV/AIDS and food insecurity are two of the leading causes of morbidity and mortality in sub-Saharan Africa, with each heightening the vulnerability to, and worsening the severity of, the other. Less research has focused on the social determinants of food insecurity in resource-limited settings, including social support and HIV-related stigma. In this study, we analyzed data from a cohort of 456 persons from the Uganda AIDS Rural Treatment Outcomes study, an ongoing prospective cohort of persons living with HIV/AIDS (PLWHA) initiating HIV antiretroviral therapy in Mbarara, Uganda. Quarterly data were collected by structured interviews. The primary outcome, food insecurity, was measured with the Household Food Insecurity Access Scale. Key covariates of interest included social support, internalized HIV-related stigma, HIV-related enacted stigma, and disclosure of HIV serostatus. Severe food insecurity was highly prevalent overall (38%) and more prevalent among women than among men. Social support, HIV disclosure, and internalized HIV-related stigma were associated with food insecurity; these associations persisted after adjusting for household wealth, employment status, and other previously identified correlates of food insecurity. The adverse effects of internalized stigma persisted in a lagged specification, and the beneficial effect of social support further persisted after the inclusion of fixed effects. International organizations have increasingly advocated for addressing food insecurity as part of HIV/AIDS programming to improve morbidity and mortality. This study provides quantitative evidence on social determinants of food insecurity among PLWHA in resource-limited settings and suggests points of intervention. These findings also indicate that structural interventions to improve social support and/or decrease HIV-related stigma may also improve the food security of PLWHA.     

Views of dermatopathologists about clonality assays in the diagnosis of cutaneous T‐cell and B‐cell lymphoproliferative disorders

Background

Appropriate use criteria have been developed for many tests using expert judgment, evidence‐based practice and clinical experience. In this context, we report the opinions of practitioners about clonality assays in various clinical scenarios where cutaneous lymphoma is suspected.

Methods

An Appropriate Use Criteria Task Force sponsored by the American Society of Dermatopathology (ASDP) synthesized clinical scenarios for cutaneous lymphoproliferative disorders (LPDs). We conducted, summarized and presented a relevant literature search to an audience of 144 dermatopathologists with a variety of practice experiences at the 53rd Annual Meeting of the ASDP in Chicago, IL.

Results

Twenty‐seven clinical scenarios for LPDs (13 T‐cell and 14 B‐cell) were defined. Forty relevant studies for T‐cell receptor gene clonality assays and 20 relevant studies for IgH/IgK clonality assays were identified. Audience response data from participating dermatopathologists reflected a wide variety of approaches to the application of clonality assays in the evaluation of LPDs, based on practice setting, personal experience and test availability.

Conclusions

Our clinical scenario analysis and literature review revealed well‐supported clinical scenarios and identified opportunities for additional research to further define the utility of clonality assays in some clinical scenarios.     

Packaged Foods Labeled as Organic Have a More Healthful Profile Than Their Conventional Counterparts,According to Analysis of Products Sold in the U.S. in 2019–2020

The organic food market’s recent rapid global growth reflects the public’s interest in buying certified organic foods, including packaged products. Our analysis shows that packaged foods containing fewer ingredients associated with negative public health outcomes are more likely to be labeled organic. Previous studies comparing organic and conventional foods focused primarily on nutrient composition. We expanded this research by additionally examining ingredient characteristics, including processing and functional use. Our dataset included nutrition and ingredient data for 8240 organic and 72,205 conventional food products sold in the U.S. from 2019 to 2020. Compared to conventional foods, organic foods in this dataset had lower total sugar, added sugar, saturated fat and sodium content. Using a mixed effects logistic regression, we found that likelihood of classification as organic increased as sodium content, added sugar content and the number of ultra-processed ingredients and cosmetic additives on the product label decreased. Products containing no trans-fat ingredients were more likely to be labeled organic. A product was more likely to be classified “organic” the more potassium it contained. These features of organic foods sold in the U.S. are significant because lower dietary ingestion of ultra-processed foods, added sugar, sodium and trans-fats is associated with improved public health outcomes.
