¿Queratoquiste odontogénico o quiste primordial? Actualización diagnóstica y terapéutica

Introduction: odontogenic keratocyst has histopathological significance, with interesting biological and pathological behavior. Its high recurrence rate and great capacity to destroy areas of medullary bone make it one of the most aggressive cysts.Objective: to characterize the diagnosis and update treatment of odontogénico keratocyst.Method: an updated bibliographic review on the subject was carried out in the period between February and April 2021. The search used textbooks and the resources available on the Infomed network, specifically: PubMed, SciELO and Ebesco, through databases: Medline, Academic Search Premier, MedicLatina; in addition to Cudmed, Lilacs and Scopus. From a total of 56 articles related to the topic, 24 were selected according to date and relevance.Development: keratocysts are asymptomatic, founds by chance during radiographic examinations. The therapeutic approach should be based on the patient's age, lesion location, cyst size, recurrence status, and radiographic evidence of cortical perforation.Conclusions: radiology is, without doubt, the first method used in the diagnosis of cysts; however, the histopathological analysis is in charge of establishing the definitive diagnosis. Several are the treatments described in the literature; excision and curettage are essential in cases, always giving the patient a clinical and radiographic follow-up for a period of 5 years.Introducción: el queratoquiste odontogénico encierra un significado histopatológico, con un comportamiento biológico y patológico interesante. Su alta tasa de recurrencia y gran capacidad para destruir áreas de hueso medular lo sitúan como uno de los quistes más agresivos.Objetivo: caracterizar el diagnóstico y tratamiento actualizado del queratoquiste odontogénico.Método: se realizó una revisión bibliográfica actualizada con relación al tema en el período comprendido entre febrero y abril de 2021. En la búsqueda se emplearon libros de texto y los recursos disponibles en la red Infomed, específicamente: PubMed, SciELO y Ebesco, a través de las bases de datos: Medline, Academic Search Premier, MedicLatina; además de Cudmed, Lilacs y Scopus. De un total de 56 artículos relacionados con la temática fueron seleccionados 24 de acuerdo a la fecha y relevancia.Desarrollo: los queratoquistes son asintomáticos, hallados casualmente durante la realización de exámenes radiográficos. El enfoque terapéutico debe basarse según la edad del paciente, la ubicación de la lesión, el tamaño del quiste, el estado de recidiva y la evidencia radiográfica de perforación cortical.Conclusiones: la radiología es, sin dudas, el primer método empleado en el diagnóstico de los quistes; sin embargo, el análisis histopatológico es el encargado de establecer el diagnóstico definitivo. Varios son los tratamientos descritos en la literatura; la exéresis y el cureteado son fundamentales en estos casos, siempre dando al paciente un seguimiento clínico y radiográfico por un período de 5 años

Implementation and Knowledge of the Clinical Practice Guide for Palliative Care in the Ecuadorian Primary Care Level

Ecuador assumed the commitment of including Palliative Care (PC) in its health policies. In 2014, the Ministry of Public Health (Ministerio de Salud Pública, MSP) approved the Clinical Practice Guide for Palliative Care (Guía de Práctica Clínica sobre Cuidados Paliativos, GPCCP), with application at the national level, as a mandatory internal regulation in all institutions belonging to the National Health System. In 2021, there is no evidence about the degree of implementation. The objective was to evaluate the implementation (I) of the GPCCP guide and the knowledge (C) of the health personnel working in the Zone 7 Health Centers (HCs). This is a cross-sectional, descriptive, and prospective study. A total of 292 professionals were interviewed: managers (38), physicians (150), and nurses (104). Three surveys based on the GPCCP guide were elaborated: one for the implementation, which was applied to the individuals in charge, and the others to assess the health professionals’ knowledge. The SPSS program was used, version 25. In the three groups, more than half of the participants had no training in PC, 91.2% of the HCs have the GPCCP guide, there is PC medical history (MH) in 38.2%, and morphine is used in 14.7%. The implementation of the GPCCP guide was inadequate in 52.9% of the cases. Only 25% treat the agony symptoms and 30%, delirium; 4.4% acknowledge the use of morphine in dyspnea, and 13.3% identify the subcutaneous route as the first choice for hydration at the end-of-life phase. Strategies to implement the GPCCP guide and to improve the health personnel’s knowledge must be implemented in Zone 7 centers

A Multiple-Choice Maze-like Spatial Navigation Task for Humans Implemented in a Real-Space, Multipurpose Circular Arena

Spatial navigation is a key aspect of human behavior and it is still not completely understood. A number of experimental approaches exist, although most of the published data in the last decades have relied on virtual maze on-screen simulation or not-completely freely moving 3D devices. Some interesting recent developments, such as circular mazes, have contributed to analyze critical aspects of freely moving human spatial navigation in real space, although dedicated protocols only allow for simple approaches. Here, we have developed both specifically designed and home-assembled hardware equipment, and a customized protocol for spatial navigation evaluation in freely moving humans in a real space circular arena. The spatial navigation protocol poses an imitation of a real-space multiple-choice path maze with cul-de-sac and instances of non-linear movement. We have compared the results of this system to those of a number of validated, both virtual and real, spatial navigation tests in a group of participants. The system composed by hardware, the test protocol, and dedicated measure analysis designed in our laboratory allows us to evaluate human spatial navigation in a complex maze with a small and portable structure, yielding a highly flexible, adaptable, and versatile access to information about the subjects’ spatial navigation abilities

Flavonoid Intake From Cocoa-Based Products and Adiposity Parameters in Adolescents in Spain.

Cocoa-based products are a good source of flavonoids, which may have beneficial effects on metabolic health. The aim of this study is to assess the relationship between flavonoids from cocoa-based products and adiposity parameters in adolescents. A cross-sectional study was conducted involving 944 adolescents aged 11-14 years enrolled in the SI! Program for Secondary Schools trial in Spain with available baseline data from food frequency questionnaires and anthropometric measurements [weight, height, waist circumference (WC), and fat mass percentage (% FM) by bioimpedance analysis]. Fat mass index (FMI) and waist-to-height ratio (WHtR) were obtained by dividing fat mass by height and WC by height, respectively. Body mass index (BMI), WC, and FMI for age and gender z-score were calculated. Overweight/obesity was defined as BMI ≥ 85th percentile and excess adiposity as %FM or FMI ≥ 75th percentile. WC ≥ 90th percentile and WHtR with a 0.5 threshold were considered as criteria of abdominal obesity. Multilevel mixed-effect regressions were used to evaluate the association between flavonoids from cocoa-based products and adiposity parameters. Municipalities and schools were considered random effects. Participants with a higher flavonoid intake from cocoa-based products had lower WC z-score [B = -0.04, 95% CI (-0.07; -0.01), P-for trend = 0.045] and WHtR [B = -0.01, 95% CI (-0.02; -0.01), P- for trend < 0.001]. They also had lower probability of having abdominal obesity [OR 0.66, 95% CI (0.52; 0.85), P- for trend = 0.001]. Inverse associations were observed between flavonoids from cocoa powder and BMI z-score [B = -0.08, 95% CI (-0.12; -0.05), P < 0.001], WC z-score [B = -0.06, 95% CI (-0.11; -0.02), P = 0.003], WHtR [B = -0.01, 95% CI (-0.01; -0.00), P < 0.001], %FM [B = -1.11, 95% CI (-1.48; -0.75), P < 0.001], and FMI z-score [B = -0.18, 95% CI (-0.20; -0.17), P < 0.001]. Regarding dark chocolate, an inverse association only with WC z-score [B = -0.06, 95% CI (-0.08; -0.05), P < 0.001] was found. However, no association was observed between flavonoids from milk chocolate intake and anthropometric parameters. A higher intake of flavonoids from cocoa-based products was associated with lower adiposity parameters and a lower probability of presenting abdominal obesity.The SI!

Metabolic syndrome, adiposity, diet, and emotional eating are associated with oxidative stress in adolescents

Background: Metabolic syndrome (MS), a condition related to adiposity and oxidative stress, can develop in adolescence, a critical stage in life that impacts health in adulthood. However, there is scarce scientific research about the relationship between lifestyle factors, emotion management, and oxidative stress in this phase of life.Aim: To analyze whether nutritional parameters, lifestyle factors, emotion management, and MS in adolescents are associated with oxidative stress measured by the biomarker 8-isoprostane.Methods: A cross-sectional study was carried out in 132 adolescents (48.5% girls, aged 12 ± 0.48 years) and data were collected on nutritional parameters (anthropometric measurements, biochemical analyzes, and blood pressure), lifestyle factors (physical activity, sleep, and diet), and emotion management (self-esteem, emotional eating, and mood). 8-isoprostane was analyzed in spot urine samples. The study population was categorized in three groups (healthy, at-risk, and with MS) using the International Diabetes Federation definition of MS in adolescents. To capture more complex interactions, a multiple linear regression was used to analyze the association between 8-isoprostane and the aforementioned variables.Results: Urinary 8-isoprostane levels were significantly higher in the MS group compared to the healthy group (1,280 ± 543 pg./mg vs. 950 ± 416 pg./mg respectively). In addition, univariable analysis revealed positive significant associations between 8-isoprostane and body mass index, waist circumference, waist-to-height ratio, body fat percentage, blood lipid profile and glucose, emotional eating, and refined cereal intake. Conversely, a negative significant association was found between 8-isoprostane and sleep duration and fish intake. The multiple linear regression analysis revealed associations between 8-isoprostane and LDL-c (β = 0.173 value of p = 0.049), emotional eating (low β = 0.443, value of p = 0.036; high β = 0.152, value of p = 0.470), refined cereal intake (β =0.191, value of p = 0.024), and fish intake (β = -0.187, value of p = 0.050).Conclusion: The MS group, LDL-c, emotional eating, and high refined cereals and low fish intakes were associated with higher levels of oxidative stress in an adolescent population.</p
