RESUMO
HIV stigma is a social determinant of health that can influence multiple health outcomes, including adherence to antiretroviral therapy (ART), engagement in HIV care, and viral suppression levels in people with HIV (PWH). In Peru, where the HIV epidemic is concentrated in men who have sex with men (MSM) and transgender women (TGW), stigma may play an important role in healthcare engagement. To understand the relationship between stigma and two outcome variables, ART adherence and engagement in HIV care in 400 MSM and TGW, we assessed factors from the Behavioral Model for Vulnerable Populations at two HIV clinics that tailor services for sexual and gender minorities. While some predisposing, need, and enabling resource factors were associated with optimal (≥ 90%) ART adherence or engagement in HIV care, none of the stigma subscales were correlated, suggesting that when LGBTQ-affirming care is provided to MSM/TGW, stigma may not influence HIV-related outcomes.
RESUMEN: El estigma hacia el VIH es un determinante social de la salud que puede influir en múltiples desenlaces, incluyendo la adherencia a la terapia antirretroviral (TAR), el compromiso con la atención del VIH y los niveles de supresión viral en personas viviendo con VIH (PVV). En el Perú, donde la epidemia del VIH se concentra en hombres que tienen sexo con hombres (HSH) y mujeres transgénero (MT), el estigma puede desempeñar un papel importante en el compromiso con la atención médica. Para comprender la relación entre el estigma y dos variables de resultado, la adherencia al TAR y el compromiso con la atención del VIH en 400 HSH y MT, evaluamos factores del Modelo de Comportamiento para Poblaciones Vulnerables en dos clínicas de VIH que adaptan sus servicios para minorías sexuales y de género. Si bien algunos factores predisponentes, de necesidad y de recursos habilitantes se asociaron con una adherencia óptima (≥ 90%) al TAR o al compromiso con la atención del VIH, ninguna de las sub-escalas de estigma estuvieron correlacionadas, sugiriendo que cuando se brinda atención que afirma a la comunidad LGBTQ a HSH/MT, el estigma puede no influir en los desenlaces relacionados con el VIH.

AIMS: Increasing evidence supports a relationship between poor oral health and growth in children. Our objective was to assess the association between the presence of dental caries and anthropometric measurements of children residing in Claverito, a floating slum community in the Peruvian Amazon. METHODS: For this cross-sectional study, presence of caries was assessed using dmft/DMFT (decayed, missing, filled teeth) scores and the SiC Index (mean dmft/DMFT of one-third of the study group with the highest caries score). Anthropometric categories for age-sex-specific z-scores for height and weight were calculated based on WHO standardized procedures and definitions. The association between SiC (measured by dmft/DMFT) and anthropometric measures was estimated using unadjusted and adjusted multivariable linear regression models. Critical value was established at 5%. RESULTS: Our study population consisted of 67 children between the ages of 1 and 18 years old. Mean age was 9.5 years old (SD: 4.5), and the majority were female (52.2%). Almost all had dental caries (97.0%) and the mean dmft/DMFT score was 7.2 (SD: 4.7). The SiC Index of this population was 9.0. After adjusting for confounding variables, participants who had permanent dentition with the highest dmft/DMFT levels had statistically significant decreased height-for-age z-scores (HAZ) (p=0.04). CONCLUSIONS: We found an inverse linear association between SiC Index and height-for-age z-scores (HAZ) among children living in poverty in a floating Amazonian community in Peru. Children from under-resourced communities, like floating slums, are at high risk for oral disease possibly negatively impacting their growth and development.

Resumo Objetivos: Há cada vez mais evidências apoiando uma relação entre a saúde bucal precária e o crescimento das crianças. Nosso objetivo foi avaliar a associação entre a presença de cárie dentária e medidas antropométricas de crianças residentes em Claverito, uma comunidade flutuante de favelas na Amazônia peruana. Métodos: Para este estudo transversal, a presença de cárie foi avaliada utilizando os escores dmft/DMFT (dentes cariados, ausentes, preenchidos) e o Índice SiC (média dmft/DMFT de um terço do grupo de estudo com a maior pontuação de cárie). As categorias antropométricas para pontuações z específicas de idade e sexo para altura e peso foram calculadas com base nos procedimentos e definições padronizados da OMS. A associação entre SiC (medido por dmft/DMFT) e medidas antropométricas foi estimada usando modelos de regressão linear multivariável não ajustados e ajustados. O valor crítico foi estabelecido em 5%. Resultados: A população do estudo consistia de 67 crianças entre 1 e 18 anos de idade. A idade média era de 9,5 anos (DP: 4,5), e a maioria era do sexo feminino (52,2%). Quase todas tinham cárie dentária (97,0%) e a média da pontuação dmft/DMFT foi de 7,2 (DP: 4,7). O índice SiC desta população era de 9,0. Após ajuste para variáveis confusas, os participantes que tinham dentição permanente com os níveis mais altos de dmft/DMFT tinham diminuído estatisticamente a pontuação z de altura por idade (HAZ) (p=0,04). Conclusões: Encontramos uma associação linear inversa entre o Índice SiC e as pontuações z de altura por idade (HAZ) entre crianças que vivem na pobreza em uma comunidade amazônica flutuante no Peru. Crianças de comunidades com poucos recursos, como favelas flutuantes, correm alto risco de contrair doenças orais, possivelmente impactando negativamente seu crescimento e desenvolvimento.
RESUMO
The purpose of this study was to compare the performance of chemomechanical caries removal (CMCR) with that of conventional drilling for efficacy of caries removal, time spent, morphological changes and microhardness of surface dentin, and microleakage of subsequent restorations. Forty-six carious deciduous molars were randomly divided into two groups: one each for caries removal by (1) CMCR and by (2) drilling. The completeness of caries removal was evaluated by visual and tactile criteria and a caries detector device. Twenty teeth in each group were restored with glass ionomer (GI) and subjected to thermocycling before undergoing microleakage and microhardness tests. In each group, three restored teeth were used for polarized light microscopic analysis, and three unrestored teeth for scanning electron microscopy (SEM). There was no significant difference in the completeness of caries removal between groups. However, time spent for caries removal by CMCR was significantly longer than that required for drilling. Restorations in the CMCR group had significantly more microleakage than those in the drilling group. Dentin hardness of the cavity floor after CMCR was also significantly lower. Microscopic analyses showed roughened and irregular dentin surfaces in the CMCR group, unlike the smooth surfaces observed in the drilling group. In conclusion, CMCR was as efficacious as drilling in term of completeness of caries removal, but required longer excavation times and resulted in lower microhardness of residual dentin as well as more microleakage after restorations with GI. Further laboratory and clinical evaluations on the efficiency and performance of CMCR for the durability of subsequent restorations are required.
