Introducción. El conjunto de estrategias de recuperación mejorada después de la cirugía (ERAS, por sus siglas en inglés) constituye un enfoque de atención multimodal y multidisciplinario, cuyo propósito es reducir el estrés perioperatorio de la cirugía, disminuir la morbilidad y acortar la estancia hospitalaria. Este estudio tuvo como objetivo describir los resultados clínicos de pacientes sometidos a cirugía por cáncer colorrectal, identificando las complicaciones principales y los factores perioperatorios relacionados con el alta temprana. Métodos. Se analizaron los pacientes consecutivos sometidos a cirugía colorrectal entre los años 2020 y 2023, todos los cuales siguieron el protocolo ERAS institucional. Se evaluaron las características clínicas, los factores perioperatorios, los desenlaces postoperatorios y la tasa global de adherencia al protocolo. Resultados. Un total de 456 pacientes fueron sometidos a cirugía colorrectal, 51% de sexo masculino, con edad media de 60 años. La mayoría de las intervenciones se realizaron por laparoscopia (78 %), con una tasa de conversión del 14,5 %. Las complicaciones postoperatorias incluyeron fuga anastomótica (4,6 %), sangrado, infección intraabdominal y obstrucción intestinal. La estancia hospitalaria promedio fue de 4 días y la mortalidad del 2,8 %. La tasa global de adherencia al protocolo ERAS fue del 84,7 %. Conclusiones. El enfoque combinado de cirugía laparoscópica y protocolo ERAS es factible, seguro y se asocia con una estancia hospitalaria más corta. La implementación y adherencia al protocolo ERAS no solo mejora los resultados postoperatorios, sino que también resalta la importancia de acceder a datos sólidos, permitiendo mejorar la atención perioperatoria local.

Introduction. The Enhanced Recovery After Surgery (ERAS) protocol is a multimodal, multidisciplinary approach to care, the purpose of which is to reduce the perioperative stress of surgery, decrease morbidity, and shorten hospital stay. This study aimed to describe the clinical outcomes of patients undergoing surgery for colorectal cancer, identifying the main complications and perioperative factors related to early discharge. Methods. Consecutive patients undergoing colorectal surgery between 2020 and 2023 were analyzed, who followed the institutional ERAS protocol. Clinical characteristics, perioperative factors, postoperative outcomes, and overall protocol adherence rate were evaluated. Results. A total of 456 patients underwent colorectal surgery, 51% male, with a mean age of 60 years. Most interventions were performed laparoscopically (78%), with a conversion rate of 14.5%. Postoperative complications included anastomotic leak (4.6%), followed by bleeding, intra-abdominal infection, and intestinal obstruction. The average hospital stay was 4 days and mortality was 2.8%. The overall adherence rate to the ERAS protocol was 84.7%. Conclusions. The combined approach of laparoscopic surgery and ERAS protocol is feasible, safe, and associated with a shorter hospital stay. Implementation and adherence to the ERAS protocol not only improves postoperative outcomes, but also highlights the importance of accessing solid data, allowing for improved local perioperative care.

Teratoma mesentérico maduro en una mujer adulta: reporte de caso y revisión de la literatura / Mature mesenteric teratoma in an adult women: Case report and literature

Introducción. Los teratomas son neoplasias que surgen a partir de células germinales pluripotenciales y derivan de dos o más capas de células. Se clasifican en tumores maduros, que contienen tejidos bien diferenciados, o inmaduros, que contienen estructuras inmaduras y embrionarias. Su localización más frecuente son las gónadas; la ubicación mesentérica es infrecuente y se han descrito aproximadamente 40 casos en la literatura mundial. Dentro del abordaje diagnóstico y terapéutico, se emplea la tomografía computarizada y la resonancia magnética nuclear para caracterizar la lesión, evaluar la extensión intraabdominal y la relación con otras estructuras. El diagnóstico debe confirmarse mediante el examen histopatológico. Caso clínico. Paciente femenina de 56 años, con antecedente de carcinoma ductal infiltrante de mama izquierda en remisión, en estudios de seguimiento con hallazgo incidental en tomografía de abdomen de lesión abdominopélvica dependiente del mesenterio, contornos lisos y nivel grasa-líquido. Estudios de extensión con marcadores tumorales negativos. Resultados. Por la alta sospecha clínica e imagenológica de teratoma, fue llevada a resección quirúrgica de la lesión. El examen histopatológico confirmó el diagnóstico de teratoma quístico maduro del mesenterio. Conclusión. El teratoma mesentérico es una entidad clínica rara, que debe ser considerado como uno de los diagnósticos diferenciales de una masa abdominal con efecto compresivo. El diagnóstico se basa principalmente en el examen clínico y los hallazgos imagenológicos. La escisión quirúrgica temprana es el pilar del tratamiento; el abordaje laparoscópico o abierto depende de las características clínicas y la experiencia del cirujano.

Background. Teratomas are neoplasms that arise from pluripotent germ cells, derived from two or more layers of germ cells. They are classified as mature tumors (cystic or solid), which contain well-differentiated tissues, or as immature tumors, which contain immature and embryonic structures. Its most frequent location is the female and male gonads; the mesenteric location is rare and approximately 40 cases have been described in the world literature. Within the diagnostic and therapeutic approach, computed tomography and magnetic resonance imaging are used to characterize the lesion, assess intra-abdominal extension and the relationship with other structures. The diagnosis must be confirmed by histopathological examination. Clinical case. A 56-year-old female patient with a history of infiltrating ductal carcinoma of the left breast in remission. In follow-up studies, incidental abdominal tomography finding of an abdominopelvic lesion dependent on the mesentery at the level of the mesogastrium, smooth contours with fat-liquid level. Extension studies with negative tumor markers. Results. Due to high clinical and imaging suspicion of teratoma, the patient was taken to resection of the lesion. Histopathological examination confirmed the diagnosis of mature cystic teratoma of the mesentery. Conclusion. Mesenteric teratoma is a rare clinical entity and is considered one of the differential diagnoses of an abdominal mass with a compressive effect. Diagnosis is mainly based on clinical examination and imaging findings. Early surgical excision is the mainstay of treatment; laparoscopic or open approach depends on the clinical characteristics and the experience of the surgeon.

Sodium content in commonly consumed away-from-home food in three areas of Metropolitan Lima, Peru. / Contenido de sodio en preparaciones de consumo frecuente fuera del hogar en tres zonas de Lima Metropolitana, Perú.

The aim of this study was to characterize the sodium content in commonly consumed away-from-home food in three areas of Metropolitan Lima. We conducted a cross-sectional study, in which twenty frequently consumed foods were identified according to the place of sale. Sodium content was determined through atomic absorption spectroscopy in preparations collected in 2019. The median sodium content in street food products was 492.36 mg/100g (IQR: 83.93 - 918.78), 471.37 mg/100 g in artisanal food (IQR: 76.04 - 765.39) and 471.06 mg/100 g in fast food (IQR: 115.31 - 695.18). Sixty-five percent of the foods were classified as having high sodium content according to Peruvian regulations, while 30% of the preparations had high sodium content, according to UK parameters. Most food sold and consumed away from home have high sodium content. It is essential to engage all stakeholders involved in food preparation for away-from-home consumption in order to raise awareness and involve them in the promotion of policies aimed at reducing sodium intake.

El 65% de las preparaciones fueron consideradas altas en sodio según los parámetros peruanos, mientras que el 30% de las preparaciones también presentaron un alto contenido, de acuerdo con los parámetros del Reino Unido. La mayoría de las preparaciones expendidas y consumidas fuera del hogar presentan un elevado contenido de sodio. Es esencial involucrar a todos los actores que participan en la preparación de alimentos para el consumo fuera del hogar, con el fin de sensibilizarlos e incluirlos en la promoción de políticas enfocadas en la reducción del consumo de sodio.

Performance Analysis of Embedded Multilayer Perceptron Artificial Neural Networks on Smart Cyber-Physical Systems for IoT Environments.

At present, modern society is experiencing a significant transformation. Thanks to the digitization of society and manufacturing, mainly because of a combination of technologies, such as the Internet of Things, cloud computing, machine learning, smart cyber-physical systems, etc., which are making the smart factory and Industry 4.0 a reality. Currently, most of the intelligence of smart cyber-physical systems is implemented in software. For this reason, in this work, we focused on the artificial intelligence software design of this technology, one of the most complex and critical. This research aimed to study and compare the performance of a multilayer perceptron artificial neural network designed for solving the problem of character recognition in three implementation technologies: personal computers, cloud computing environments, and smart cyber-physical systems. After training and testing the multilayer perceptron, training time and accuracy tests showed each technology has particular characteristics and performance. Nevertheless, the three technologies have a similar performance of 97% accuracy, despite a difference in the training time. The results show that the artificial intelligence embedded in fog technology is a promising alternative for developing smart cyber-physical systems.

The sodium borate relieves the hypertrophic damage induced during pregnancy, it improves contractibility, reduces oxidative stress and stimulates cell proliferation.

INTRODUCTION: Fetal and postnatal hypertrophy develop in response to such different exposures or illnesses the mother suffers during gestation as anti-infectious and physical agents, obesity, hypertension, diabetes, and even advanced maternal age. This gives rise to high comorbidities in the newborn; therefore, looking for alternatives that contribute to cardiac homeostasis is quite necessary to inhibit the overgrowth of myocytes. Boron-derivative compounds could play a key role in exerting a repairing effect on chronic cardiac damage induced during gestation. METHODOLOGY: The cardiotoxic effect of 6.4, 12 and 100 mg/kg of sodium tetraborate administered by oral delivery route to healthy pregnant mice was assessed. After that, the use of the chemical compound was tested in the treatment of pregnant mice previously subjected to isoproterenol (fetal hypertrophy model) on the fifth day post coitus. Prior to the sacrifice of the pups of mice an electrocardiography (ECG) was done. Morphological and histological changes of heart were assessed in newborn pups. As a damage marker, the concentration of p38 nitrogen-activated protein kinases were evaluated by using Western Blot and the levels of malondialdehyde (MDA) as well as glutathione antioxidants (GSH) and glutathione peroxidase (GPx) were tested by spectrometry. Moreover, the mRNA expression for early response genes (c-jun, c-fos y c-myc), late response (GATA-4, Mef2c, NFAT) and heart damage (ANP and BNP) was measured by qPCR real time. RESULTS: The supply of 6,4 and 12 mg/kg-sodium tetraborate favored ventricular remodeling with histological alterations. By comparison, 100 mg/kg of sodium tetraborate administered during the fetal stage did not alter neither the cardiac morphology of six-week old pups nor the p38/P-p38MAPK ratio remained the same and no oxidative stress was observed. When pregnant females treated with isoproterenol were treated with 100 mg/kg sodium tetraborate during the fetal stage, an improvement in contractility was detected in the pups with an actual reduction in myocardial fibrosis and oxidative stress, but cardiac mass increased. In addition, the expression levels of c-jun, c-myc, GATA-4, MEF2c and ANP mRNA declined in comparison with CTR. However, the hypertrophic damage mechanism was sustained by c-fos, NFAT and BNP expressions. CONCLUSIONS: The set of results achieved suggests that high concentrations of sodium tetraborate have no cardiotoxic effects. Furthermore, sodium tetraborate mitigates hypertrophy induced during pregnancy, thereby improving contractibility, reducing oxidative stress and stimulating cell proliferation. Therefore, sodium tetraborate could be an excellent prophylactic treatment administered by delivery oral route during pregnancy when there is a risk of developing fetal left ventricular hypertrophy (LVH).

Knee skin temperature response of patients with bilateral patellofemoral syndrome before and after heat and cold stress.

Patellofemoral Pain Syndrome is characterized by the presence of pain in the front area of the knee, which occurs when performing common activities such as climbing stairs, and bending the knees, among others. The objective of this research was to evaluate the detection capability of infrared thermography in patients with Patellofemoral Pain Syndrome, in the baseline state, as well as after the application of thermal stress. The investigation was conducted in 48 patients, who were subdivided into four groups (n = 12). Two subgroups were healthy patients and two with Patellofemoral Pain Syndrome. For the diagnosis of the syndrome, a manual evaluation was performed using the Zohlen test and Q angle measurement. Subsequently, cold stress was applied for 10 min to a healthy subgroup and an experimental subgroup. The remaining two subgroups were subjected to heat stress for 15 min. Thermographic images of the lower extremities were acquired at seven time points, at baseline, immediately after application of thermal stress and then every 3 min until 15 min were completed. It was observed that patients presented Patellofemoral Pain Syndrome bilaterally. After statistical analysis, it was found that there were no significant differences in baseline temperature between the groups. However, for heat stress, a higher temperature was observed in the group with Patellofemoral Pain Syndrome (p < 0.05) in the recovery period, and in the case of cold stress, only a lower temperature in the left knee immediately after the application. In conclusion, it is not possible to detect patellofemoral syndrome bilaterally in the baseline state by thermography and neither is it evident in cold stress. However, after heat stress, thermal recovery is lower for the PFPS group, so it would be susceptible to detection.

Educación Meditativa, una metodología para el autocuidado de académicos universitarios / Meditative Education, a Methodology for Self-care of University Scholars

Introducción: Dentro de la cultura organizacional, el profesor universitario es un agente clave para el logro de los aprendizajes, coordinando diariamente las solicitudes de las asignaturas y carrera, junto a las necesidades estudiantiles. Por esto, la docencia es una de las profesiones con mayor riesgo de padecer estrés, así como ansiedad y depresión. Con el objetivo de disminuir dichos factores se han creado programas para docentes con diversas actividades que promueven el autocuidado. Objetivo: Demostrar la efectividad del Programa de Educación Meditativa del Sistema Isha Judd en la disminución de los niveles de estrés, depresión y ansiedad de docentes de la Facultad de Ciencias de la Salud de la Universidad Autónoma de Chile. Métodos: Se desarrollaron 10 talleres presenciales dirigidos por facilitadores del Sistema ISHA Judd. Los inscritos se dividieron en tres grupos que sesionaron los lunes, en horarios diferidos (n = 22). Las reuniones fueron cada 15 días, cada sesión se dividió en seis momentos. En la primera y última sesión se realizaron Test Depresión y Ansiedad de Beck, Escala de Autoestima de Rossemberg, Escala de Estrés Percibido y encuesta de bienestar del Sistema Isha Judd. Resultados: El nivel de estrés del grupo bajó en 7,2 puntos pasando de moderado a bajo, el nivel de depresión bajó significativamente, al igual que los valores de ansiedad, llegando a leve y mínimo. El nivel de autoestima inicialmente estaba en el rango alto y al finalizar se mantuvo en el mismo rango, pero mejorando el puntaje promedio en 1,88. Conclusión: En aquellos docentes que cumplieron con los requerimientos mínimos del programa, esta metodología impactó positivamente en su satisfacción, mejorando en promedio sus niveles de estrés, ansiedad, depresión y autoestima. Este estudio presenta limitaciones por el número y tipo de muestra por lo que se sugiere realizar una segunda etapa(AU)

Introduction: Within the organizational culture, the university professor is a key agent for the achievement of learning, coordinating daily the requests of the subjects and majors, together with the students' needs. For this reason, teaching is one of the professions with the highest risk of experiencing stress, as well as anxiety and depression. In order to reduce these factors, programs have been created for teachers with various activities that promote self-care. Objective: To demonstrate the effectiveness of the Meditative Education Program of the Isha Judd System in reducing the levels of stress, depression and anxiety in teachers of the School of Health Sciences of the Universidad Autónoma de Chile. Methods: Ten face-to-face workshops were conducted by facilitators of the Isha Judd System. The participants were divided into three groups that met on Mondays, at different times (n = 22). The meetings were held every 15 days, each session was divided into six moments. In the first and last session, Beck's Depression and Anxiety Test, Rossemberg's Self-Esteem Scale, Perceived Stress Scale and the Isha Judd System wellbeing survey were applied. Results: The stress level of the group decreased by 7.2 points, going from moderate to low, the depression level decreased significantly, as did the anxiety values, reaching mild and minimal. The level of self-esteem was initially in the high range and at the end it remained in the same range, but the average score improved by 1.88 points. Conclusion: In those teachers who met the minimum requirements of the program, this methodology had a positive impact on their satisfaction, improving on average their levels of stress, anxiety, depression and self-esteem. This study has limitations due to the number and type of sample, so a second stage is suggested(AU)

Association between developmental defects of enamel and early childhood caries in children under 6 years old: A systematic review and meta-analysis.

Early childhood caries (ECC) are an oral health problem worldwide in children under 6 years of age. This disease of rapid development has a multifactorial etiology, and one of the possible risk factors is developmental defects of enamel (DDE), such as hypoplasia and opacities. The aim of this systematic review was to evaluate the association between DDE and ECC in children under 6 years of age. An electronic search was conducted until March 2022 using Medline (PubMed), Scopus, Science-Direct, LILACS, Web of Science, Cochrane Library, EBSCO-Host, EMBASE, and Google Scholar and complemented with a manual search, with no restrictions on language or date of publication. Longitudinal studies of children under 6 years of age with primary dentition were included. A total of 1158 studies were found, of which 651 records were reviewed by title and abstract, and 24 articles were selected for full-text evaluation. Finally, nine studies that met the selection criteria were included in the qualitative synthesis. Study quality and certainty were assessed using the Newcastle-Ottawa scale and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. Three cohort studies of good quality were included in the meta-analysis. A risk associated with DDE (RR = 1.94; 95% CI: 1.52-2.49) and a risk associated with enamel hypoplasia (RR = 5.45; 95% CI: 1.84-16.14) were found. The results for diffuse opacity (RR = 1.21; 95% CI: 0.18-8.15) and demarcated opacity (RR = 1.26; 95% CI: 0.43-3.65) were not significant. GRADE analysis presented low and very low certainty of evidence. It was concluded that there is an association between DDE and ECC. However, the results should be interpreted with caution because of the limitations of the study. The protocol for this study has been registered in PROSPERO under identification number CRD42021238919.

Shiga toxin-producing Escherichia coli O157 in piglets and food from backyard systems.

Piglets suffer from diarrhea caused by the Shiga toxin-producing Escherichia coli (STEC) and can be carriers of the bacteria, with public health consequences in developing countries. The aim of the present study was to study the prevalence of STEC O157 in feces of 465 piglets and 54 food mixes from backyard systems, the antimicrobial susceptibility of STEC and the frequency of genes encoding extended-spectrum ß-lactamases. The E. coli was isolated from 75.90 % of the evaluated feces. The STEC strains were identified in 33.11% of the sampled population and in 43.60% of the piglets carrying E. coli. Among STEC strains, the stx1 gene was the most frequent (22.30%). The rfbO157 gene was amplified in 47.40% of the STEC strains. High frequencies of STEC strains were not susceptible to ampicillin, carbenicillin and tetracycline. The blaTEM gene (52) was the most frequent among strains not susceptible to ampicillin. Class 1 integrons were the most frequent in those strains. Of the identified STEC strains, 48.70% were considered as multi-drug resistant and 1.90% were considered extensively drug resistant. In the supplied food, STEC O157 strains were identified in 25.00% of the STEC strains. We conclude that the piglets from backyard systems are carriers of STEC O157 strains not susceptible to common antibiotics, including penicillins and tetracyclines. In addition, supplied food is a source of this type of pathogenic bacteria. Through their direct contact with humans, the piglets and food represent a potential source of bacterial dissemination capable of producing gastrointestinal infections in humans.

Identificación de variantes del gen BRCA 1 Y BRCA 2 en pacientes con cáncer de próstata resistente a la castración del Hospital Central Militar / Identification of BRCA 1 AND BRCA 2 gene variants in patients with castration-resistant prostate cancer at the Hospital Central Militar

Resumen El cáncer de próstata metastásico resistente a la castración (CPRC) es una neoplasia heterogénea letal entre los hombres. 30% de los tumores acumulan errores deletéreos en genes implicados en la respuesta al daño del ADN (DNA damage response en inglés, DDR). Algunos de estos genes asociados a cáncer son BRCA 1 y BRCA 2. Mutaciones en estos genes favorecen la pérdida o la modificación de la función provocando un cambio permanente y transmisible, lo que conduce al desarrollo de cáncer de próstata agresivo. El objetivo del estudio fue identificar mediante secuenciación dirigida (Next-generation sequencing; NGS) variantes génicas de BRCA 1 y BRCA 2 en el genoma de pacientes con CPRC del Hospital Central Militar. Es importante destacar que los resultados demostraron una serie de alteraciones clínicas, así como una pérdida de la función de las proteínas relacionadas con mecanismos de reparación del ADN. Curiosamente, algunas de las variantes en el gen BRCA, de las que se informa aquí, son de significado incierto, lo que nos ha sido comunicado por primera vez.

Abstract Metastatic castration-resistant prostate cancer (CRPC) is a heterogeneous lethal neoplasm among men. 30% of tumors harbor deleterious errors in genes involved in the DNA damage response (DDR). Some of these cancer-associated genes are BRCA 1 and BRCA 2. Mutations to these genes favor loss or modification of function causing a permanent and transmissible change, leading to the development of aggressive prostate cancer. The aim of the study was to identify by Next-generation sequencing (NGS) BRCA 1 and BRCA 2 gene variants in peripheral blood of patients with CRPC at the Hospital Central Militar. Importantly, the results demonstrated a number of clinical alterations, as well as a loss of function of proteins related to DNA repair mechanisms. Interestingly, some of the variants in the BRCA gene, reported here, are of uncertain significance, which has been reported to us for the first time.

Reformulation of Top-Selling Processed and Ultra-Processed Foods and Beverages in the Peruvian Food Supply after Front-of-Package Warning Label Policy.

Front-of-package warning label (FOPWL) policies incentivize the food industry to reduce the content of regulated nutrients in products. We explored changes in the content of nutrients of concern (sugar, saturated fat, trans fat, and sodium) and the percentage of products in the Peruvian food supply that would carry a FOPWL before and after Peru's implementation of FOPWLs. Longitudinal data on the top-selling foods and beverages (n = 94) were collected at three time points: three months before the implementation of the policy, four months after, and two years after. Using the nutritional information declared on products' labels, we compared quantities of nutrients of concern and the percentage of foods that would carry a FOPWL at each time point. Between the first and the third data collection, a decrease in the median sugar content of beverages was observed (from 9.0 to 5.9 g/100 mL, p = 0.005), accompanied by an increase in the use of nonnutritive sweeteners. This change drove the reduction of the percentage of beverages that would carry a FOPWL (from 59 to 31%, p = 0.011). Among foods, decreases were observed in saturated fat (from 6.7 to 5.9 g/100 g, p = 0.002). The percentage of foods that would carry a FOPWL according to their nutritional profile declined from before to after implementation of the policy (from 82 to 62%, p < 0.001). The study shows that the industry reformulated products in Peru after implementation of its FOPWL policy.

Changes in the Sodium Content of Foods Sold in Four Latin American Countries: 2015 to 2018.

In 2015, the Pan American Health Organization (PAHO) published sodium targets for packaged foods, which included two distinct levels: one "regional" and one "lower" target. Changes to the sodium content of the food supply in Latin American Countries (LAC) has not been evaluated. A repeated cross-sectional study used food label data from 2015 (n = 3859) and 2018 (n = 5312) to determine changes in the proportion of packaged foods meeting the PAHO sodium targets and the distribution in the sodium content of foods in four LAC (Argentina, Costa Rica, Paraguay, Peru). Foods were classified into the 18 food categories in the PAHO targets. The proportion of foods meeting the regional targets increased from 82.9% to 89.3% between 2015 and 2018 (p < 0.001). Overall, 44.4% of categories had significant decreases in mean sodium content. Categories with a higher proportion of foods meeting the regional and lower targets in 2018 compared to 2015 (p < 0.05) were breaded meat and poultry, wet and dry soups, snacks, cakes, bread products, flavored cookies and crackers, and dry pasta and noodles. While positive progress has been made in reducing the sodium content of foods in LAC, sodium intakes in the region remain high. More stringent targets are required to support sodium reduction in LAC.

Outcomes of COVID-19 on Latinx youth: Considering the role of adverse childhood events and resilience.

Early research on the COVID-19 pandemic has demonstrated differential impact on the Latinx community. There has been limited research exploring the mental health outcomes of the pandemic on Latinx youth. This study explores the severity of pandemic-related stress on Latinx youth considering their resilience factors and previous adverse childhood events (ACEs). Adolescents (n = 142) ages 13-18 completed measures related to exposure to the pandemic, pandemic stress, number of ACEs, resilience factors, and general demographic information. Results of multiple regression analysis found that exposure to the pandemic, ACEs, gender, and resilience factors predicted the levels of stress that youth experienced. No differences in pandemic-related stress were found between Latinx youth and their non-Latinx counterparts. Implications are discussed related to how school psychologists can support all students with culturally sensitive practices as we continue through the pandemic and beyond.

Factores de riesgo de caries en niños pre escolares de la Amazonía peruana

Objetivo: Investigar la influencia de los factores sociodemográficos y las características atribuidas al huésped, sustrato y microorganismos en el riesgo de caries de infancia temprana en niños de 2 a 5 años de una comunidad rural de la Amazonía peruana. Material y métodos: Estudio transversal en 155 niños de 2 a 5 años del distrito de Pichanaki. Se realizó un examen clínico, y cuestionario. Para el análisis de riesgo, se realizaron modelos de regresión logística univariados y multivariados, corregidos mediante el método de Holm-Bonferroni y un bootstrapping con 10000 ciclos de muestreo. Resultados: La prevalencia de caries fue del 83.3%. Los factores asociados a caries dental fueron los antecedentes de infecciones del tracto urinario durante el embarazo (p = 0.005), una higiene bucal pobre (p = 0.001), el compartir cubiertos con su cuidador principal (p = 0.018), y tener hermanos mayores con caries (p = 0.025). El análisis univariado mostró que las infecciones urinarias durante el embarazo, la mala higiene bucal, compartir cubiertos y tener hermanos mayores con caries aumentaron el riesgo de caries. El modelo multivariado mostró que solo la mala higiene bucal (OR: 1.99, 95% CI: 1.34 ­ 2.96, p = 0.001) y la infección urinaria (OR: 2.98, 95% CI: 1.13 ­ 7.81, p = 0.027) se asociaron a un mayor riesgo de caries dental. Conclusión: Las infecciones urinarias durante el embarazo y una higiene bucal inadecuada son factores fuertemente predisponentes para la caries de infancia temprana en niños de 2 a 5 años de una comunidad rural de la Amazonía peruana.
