Efficacy of Probiotic Consumption on Oral Outcomes in Children and/or Adolescents: A Meta-Analysis.

We assessed the impact of probiotics on outcomes related to caries in children and/or adolescents without underlying systemic diseases. We performed a comprehensive meta-analysis of randomised controlled trials (RCTs). Searches were performed in Embase, PubMed, Scopus and Web of Science until March 2023 for RCTs assessing probiotics with a minimum intake duration of 0.2 months vs. control (no treatment or placebo) and reporting at least one primary or secondary outcome. Primary outcomes were number of carious, Streptococcus mutans count, and Lactobacillus count; secondary outcomes were bacterial plaque index, gingival index, salivary pH, and bleeding index. We performed meta-analyses with random effects models and the inverse variance method. Effects were described as mean difference (MD) with their 95% confidence intervals (95%CI). The risk of bias was assessed with the RoB 2.0 tool. The GRADE methodology was used to assess the quality of evidence (QoE). Nineteen RCTs were included (n = 2622), with a follow-up range of 0.2 to 108 months. Probiotics had no effect on reduction of dental caries (MD -0.24 carious pieces, 95%CI -0.72 to 0.23; I2 = 52%, low QoE) or Lactobacillus count (MD -0.78 CFU/mL, 95%CI -1.65 to 0.09; I2= 52%, very low QoE) vs. control. However, probiotics probably reduced S. mutans count vs. control (MD -0.40 CFU/mL, 95%CI -0.57 to -0.24; I2 = 11%, moderate QoE). Probiotics had no effect on bacterial plaque index (MD 0.21 units of bacterial plaque, 95%CI -0. 55-0.96; I2 = 80%, very low QoE), gingival index (MD 0.04 units of gingival index, 95%CI -0.18 to 0.27; I2= 0%, low QoE), and salivary pH (MD -0.12 pH units, 95%CI -0.72 to 0.48; I2 = 92%, very low QoE) vs. control. Probiotics were found to likely reduce S. mutans counts. However, no significant effect of probiotics was observed in reducing other outcomes compared to the control group.

Características de la atención prenatal y su asociación con el lugar y tipo de parto de mujeres peruanas / Characteristics of prenatal care and its association with the place and type of delivery of peruvian women

Resumen OBJETIVO: Establecer la asociación entre las características de la atención prenatal y el lugar y tipo de finalización del embarazo de mujeres peruanas. MATERIALES Y MÉTODOS: Estudio retrospectivo, observacional, analítico y transversal, de enfoque cuantitativo, efectuado a partir del análisis de una base secundaria de datos de la Encuesta Demográfica y de Salud Familiar (ENDES) del año 2021 en la que participaron mujeres peruanas que cumplieron los criterios de selección. La asociación se evaluó mediante regresión de Poisson. RESULTADOS: Se analizaron los datos de 17,371 mujeres peruanas. El 5.55% de los partos fueron domiciliarios y el 33.75% culminaron por cesárea. La probabilidad de parto domiciliario se incrementó ante la carencia de control prenatal (p < 0.001; razón de prevalencia ajustada (RPa): 5.23), haber recibido información de sus derechos (p < 0.001; RPa:1.27) y debido a la atención encargada a enfermeras (p < 0.001; RPa:5.06) o promotores de salud (p < 0.001; RPa:1.39). La finalización del embarazo mediante cesárea fue mayor cuando la primera atención prenatal se inició durante el primer trimestre (p < 0.001; RPa:1.22), con examen de sangre (p = 0.004; RPa:1.19), escucha de latidos fetales (p = 0.001; RPa:1.48), pruebas para sífilis (p < 0.001; RPa:1.09) y VIH (p < 0.001; RPa:1.45), prescripción de hierro (p < 0.001; RPa:1.18), información para su alimentación (p < 0.001; RPa:1.21), control por parte del médico (p < 0.001; RPa:1.37) o técnico en enfermería (p < 0.001; RPa:1.26). CONCLUSIÓN: Se identificaron lascaracterísticas de la atención que determinaron el tipo y lugar de finalización del embarazo.

Abstract OBJECTIVE: To determine the association between the characteristics of prenatal care and the place and type of abortion in Peruvian women. MATERIALS AND METHODS: Retrospective, observational, analytical and cross-sectional study, with a quantitative approach, carried out from the analysis of a secondary database of the Demographic and Family Health Survey (ENDES) of the year 2021, in which Peruvian women who met the selection criteria participated. The association was assessed using Poisson regression. RESULTS: Data from 17,371 Peruvian women were analyzed. A total of 5.55% of deliveries were home births and 33.75% were caesarean sections. The odds of home delivery were increased by lack of prenatal care (p < 0.001; adjusted prevalence ratio (aPR): 5.23), having received information about their rights (p < 0.001; aPR: 1.27), and having received care from nurses (p < 0.001; aPR: 5.06) or community health workers (p < 0.001; aPR: 1.39). Termination of pregnancy by cesarean section was higher when the first prenatal care visit was initiated during the first trimester (p < 0.001; RPA: 1.22), with blood testing (p = 0.004; RPA: 1.19), fetal heart rate monitoring (p = 0.001; RPA: 1. 48), testing for syphilis (p < 0.001; RPa:1.09) and HIV (p < 0.001; RPa:1.45), prescription of iron (p < 0.001; RPa:1.18), information on nutrition (p < 0.001; RPa:1.21), monitoring by physician (p < 0.001; RPa:1.37) or nurse. CONCLUSION: Characteristics of care that determined the type and location of pregnancy termination were identified.

Efficacy of Enamel Matrix Derivative in Periodontal Regeneration Defects: A Systematic Review and Meta-Analysis.

Aim: To evaluate the efficacy of enamel matrix derivative (EMD) on periodontal regeneration defects. Materials and Methods: Four databases were searched until October 2021. Experimental animal studies evaluating the efficacy of EMD were used. The primary outcomes were bone formation (BF) and cementum formation (CF). The secondary outcomes were junctional epithelium (JE), gingival recession (GR), and clinical attachment level (CAL). Measures of effect were mean difference (MD) with 95% confidence intervals (CIs). Random-effects model were used for all meta-analyses. The Systematic Review Centre for Laboratory animal Experimentation tool was used to assess the risk of bias. Results: Seven experimental animal studies (n = 40) used with a maximum follow-up period of 3 months. Compared to control, EMD did not significantly reduce BF (MD 0.02 mm; 95% CI - 1.91-1.96; I2 = 89%). However, it increased CF (MD 1.38 mm; 95% CI 0.01-2.74; I2 = 55%). For secondary outcomes it was found that compared to control, EMD only significantly reduced JE (MD - 0.54 mm; 95% CI - 1.06 to - 0.02; I2 = 55%). However, the other secondary outcomes were not significant as in the case of GR (MD - 3. 88 mm; 95% CI - 68.29-60.53; I2 = 82%), and in CAL (MD 0.02 mm; 95% CI - 0.29-0.39; I2 = 38%). Finally, according to the risk of bias assessment, all included studies had a high risk of bias. Conclusion: EMD had no effect on BF values while it did not reduce CF. Otherwise, in the secondary outcomes, EMD only significantly reduced JE values and had no effect on GR and CAL.

Factores de riesgo asociados al parto pretérmino en madres jóvenes atendidas en un hospital de Perú / Risk factors associated with preterm labor in young mothers assisted in a hospital of Peru

Introducción: El parto pretérmino es una de las principales causas de morbilidad y mortalidad neonatal, cuyo origen está asociado con la presencia e interacción de factores relacionados con la madre y su entorno. Objetivo: Determinar los factores de riesgo asociados con el parto pretérmino en madres jóvenes atendidas en un Hospital de Lima, Perú. Métodos: Se realizó un estudio no experimental, analítico y retrospectivo de 32 madres con parto pretérmino y 292 a término (seleccionadas aleatoriamente), desde enero hasta agosto de 2016 en el mencionado centro hospitalario. Se utilizó la prueba de Ji al cuadrado o test de Fisher, según fue necesario, así como el odds ratio (OR) con sus intervalos de confianza al 95 %. Resultados: Los factores sociodemográficos como la instrucción, la ocupación y el estado conyugal no estuvieron relacionados con el parto pretérmino; en tanto, los pregestacionales (índice de masa corporal y antecedente de parto pretérmino) se asociaron significativamente y los clínicos (infección del tracto urinario, rotura prematura de membranas y preeclampsia) demostraron asociación estadística. Conclusiones: El índice de masa corporal pregestacional ≥25 kg/m2, el antecedente de parto pretérmino, la infección urinaria, la rotura prematura de membranas y la preeclampsia, incrementaron significativamente el riesgo de parto pretérmino.

Introduction: Preterm labor is one of the main causes of neonatal morbidity and mortality whose origin is associated with the presence and interaction of factors related to the mother and her environment. Objective: To determine the risk factors associated with preterm labor in young mothers assisted in a Hospital of Lima, Peru. Methods: A non experimental, analytic and retrospective study of 32 mothers with preterm labor and 292 with term delivery (selected at random), was carried out from January to August, 2016 in the hospital center above mentioned. The chi-square test of Fisher test was used, as it was necessary, as well as the odds ratio (OR) with its confidence intervals of 95 %. Results: The social demographic factors as instruction, occupation and marital status were not related to preterm labor; as long as, antenatal factors (body mass index and history of preterm labor) were significantly associated and clinical factors (urinary tract infection, early rupture of membranes and preeclampsia) demonstrated a statistical association. Conclusions: The antenatal body mass index ≥25 kg/m2, history of preterm labor, urinary infection, early rupture of membranes and preeclampsia, significantly increased the risk of preterm labor.
