RESUMO

Introducción: las mujeres y las personas trans que han ejercido el trabajo sexual se encuentran vulneradas puesto que son víctimas de discriminación por su condición laboral, por su género y por los riesgos que acarrea esta labor, y esto impacta en su situación de salud. Este estudio tuvo como objetivo conocer las percepciones sobre salud (física, mental y bucal) en cuatro mujeres que ejercen la prostitución en Medellín, a partir de sus experiencias de vida y aquellas relacionadas con su contexto social. Métodos: se realizó una investigación cualitativa con enfoque etnográfico para analizar las situaciones mencionadas de acuerdo con el objetivo general. Se contó con la participación de cuatro mujeres: dos de nacionalidad venezolana y dos de nacionalidad colombiana; se llevaron a cabo entrevistas semiestructuradas. Se realizó análisis de contenido cualitativo, lo cual permitió la generación de cuatro categorías (salud mental, salud bucal, salud general y calidad de vida). Resultados: sus discursos permitieron elucidar la conexión entre las condiciones de vida y la situación de salud. La falta de oportunidades laborales, un proceso migratorio de profundos cambios económicos y sociales, y una Colombia con inequidades y barreras de acceso a servicios de salud y sociales, son procesos determinantes de orden general, particular y singular de las precarias condiciones de salud bucal y general. Conclusiones: la población participante se encuentra en situación de vulnerabilidad social y de salud, lo cual evidencia la necesidad de políticas públicas y estrategias basadas en la realidad social que contribuyan a generar equidad en salud.

Introduction: women and trans people who have engaged in sex work are triply vulnerable since they are victims of discrimination due to their employment status, their gender, and the risks that this work entails, this impacts their health situation. This study aimed to know the perceptions about health (physical, mental, and oral) of four women who work in prostitution in Medellin, based on their life experiences and those related to their social context. Methods: qualitative research with an ethnographic approach was conducted to analyze the situations mentioned. Four women participated, two Venezuelans and two Colombians, and semi-structured interviews were conducted. Qualitative content analysis was performed, which allowed the generation of four categories (mental health, oral health, general health, and quality of life). Results: her discourses made it possible to elucidate the connection between the living conditions and the health situation. Lack of job opportunities, a migratory process of profound economic and social changes, and a Colombia with inequities and barriers to access to health and social services are determining processes of a general and singular order of the precarious conditions of oral health and general. Conclusions: the participating population is in a situation of social and health vulnerability, which shows the need for public policies and strategies based on the social reality that contribute to generating equity in health.

RESUMO

Anterior open bite (AOB) is related to functional alterations of the stomatognathic system. There are no studies concerning brain activation of the cortex comparing children with and without AOB during rest and activities such as deglutition and phonation. The aim of this study was to determine the activity of the brain cortex of children with AOB at rest and during phonation and deglutition and to evaluate the association of intelligence quotient (IQ), attention (Test of Variables of Attention, known as TOVA), beats per minute (BPM), and oxygen saturation measurement (SpO2) with brain activity in subjects with AOB. Fourteen children (seven with AOB and seven without AOB) with mixed dentition, aged 10-13 years, underwent an IQ test, TOVA, SpO2, and quantitative electroencephalography (QEEG). Electrodes were set in the scalp, according to the 10-20 protocol. Data were analyzed using statistical tests to assess comparisons between children with and without AOB. The results showed that IQ, TOVA, SpO2, or BPM did not show any statistically significant differences between the groups, except for the response time (contained in TOVA) (p = 0.03). Significant differences were found for the brain activity during rest (Condition 1) of the tongue, between children with and without AOB (p < 0.05 for alpha/theta and alpha peaks), whereas there were no differences during function (Condition 2). The findings of this investigation provide insights about the cortex activity of the brain while the tongue is in the resting position in children with AOB. This may imply an altered activity of the brain cortex, which should be considered when diagnosing and treating AOB. Other diagnostic techniques derived from investigations based on neuroscience could develop new diagnostic and therapeutic techniques to give better solutions to children with malocclusions. Treatments should be focused not only on the teeth but also on the brain cortex.

RESUMO

INTRODUCTION: Aedes (Stegomyia) aegypti is the vector for dengue, chikungunya, and Zika arboviruses. Bti-CECIF is a bioinsecticide designed and developed in the form of a solid tablet for the control of this vector. It contains Bacillus thuringiensis var. israelensis (Bti) serotype H-14. OBJECTIVE: To evaluate under semi-field and field conditions the efficacy and residual activity of Bti-CECIF tablets on Aedes aegypti larvae in two Colombian municipalities. MATERIALS AND METHODS: We tested under semi-field conditions in plastic tanks (Rotoplast™) four different Bti doses (0.13, 0.40, 0.66 and 0.93 mg/L) in the municipality of Apartadó, department of Antioquia, to assess Bti-CECIF efficacy (percentage of reduction of larval density) and the residual activity in water tanks containing A. aegypti third-instar larvae. The efficacy and residuality of the most lethal dose were subsequently evaluated under field conditions in cement tanks in the municipality of San Carlos, department of Córdoba. RESULTS: Under semi-field conditions, the highest tested dose exhibited the greatest residual activity (15 days) after which larval mortality was 80%. Under field conditions, the highest tested Bti-CECIF doses showed 100% mortality and exhibited a residual activity of seven days in 90% of the tanks. CONCLUSION: Bti-CECIF tablets effectively controlled A. aegypti larvae under field conditions for up to seven days post-treatment.

Introducción. Aedes (Stegomyia) aegypti es el vector de los arbovirus del dengue, el chikungunya y el Zika. Para el control de este vector, se diseñó y desarrolló un bioinsecticida en presentación de tableta sólida, el Bti-CECIF, que contiene Bacillus thuringiensis var. israelensis (Bti) de serotipo H-14. Objetivo. Evaluar en condiciones de 'semicampo' y de campo, la eficacia y la actividad residual de las tabletas de Bti-CECIF en larvas de A. aegypti en dos municipios colombianos. Materiales y métodos. En el municipio de Apartadó, departamento de Antioquia, se probaron bajo condiciones de 'semicampo' en tanques de plástico de 250 l (Rotoplast™) cuatro dosis diferentes de Bti (0,13, 0,40, 0,66 y 0,93 mg/l) para evaluar la eficacia del Bti-CECIF (porcentaje de reducción de la densidad larvaria) y la actividad residual en tanques de agua que contenían larvas de tercer estadio de A. aegypti. La eficacia y el efecto residual de la dosis más letal fueron posteriormente evaluadas en tanques de cemento bajo condiciones de campo en el municipio de San Carlos, departamento de Córdoba. Resultados. Bajo condiciones de 'semicampo', la mayor dosis probada exhibió la mayor actividad residual (15 días), después de lo cual la mortalidad de las larvas fue de 80 %. Bajo condiciones de campo, la máxima dosis probada de Bti-CECIF mostró una mortalidad de 100 % y exhibió una actividad residual de siete días en el 90 % de los tanques. Conclusión. Las tabletas Bti-CECIF controlaron eficazmente A. aegypti en condiciones de campo durante siete días a partir de su aplicación.

RESUMO

BACKGROUND: Periodontal disease has a multifactorial etiology; however, dental plaque and possible sleep bruxism (SB) have not been tested together in children as predictors of periodontal disease. AIM: To assess the variation of SB, dental biofilm (DBF), gingival index (GI), and plaque index (PI) between localized and generalized pathological probing depth (PPD), crestal bone loss (CBL), and lack of delineation of lamina dura (LD) and to establish the association of DBF, GI, PI and SB with PPD, CBL, and LD in children with mixed dentition. METHODS: Fifty children were assessed for SB and underwent a clinical and radiographic periodontal examination. anova and three multiple variable analysis were used to analyze the data. RESULTS: One-way anova was found to be statistically significant for SB, between localized and generalized PPD (P = 0.03), CBL (P = 0.01), and LD (P = 0.005) and for DBF between localized and generalized CBL (P = 0.02). The three multiple variable analysis showed statistically and clinically significant associations of DBF with PPD (OR = 3.33); GI (OR = 2.37), and PI (OR = 1.46) with CBL and SB (OR = 7.66) and DBF (OR = 9.87) with LD. PI presented statistically significant association with CBL. CONCLUSION: Significant associations of SB, DBF, GI, and PI with PD, CBL, and LD and the variations of the same factors between localized and generalized PPD, CBL, and LD suggest the necessity of evaluating SB, DBF, GI, and PI when children are screened in regular dental visits.
