ABSTRACT
Introducción: El conocimiento adecuado de la configuración de conductos radiculares es fundamental en endodoncia; la evaluación tomográfica permite una correcta evaluación de su disposición radicular. Objetivo: Determinar la prevalencia de conductos en C de segundos molares mandibulares, evaluados en tomografía de haz cónico. Métodos: Se realizó un estudio descriptivo y de corte transversal; la muestra estuvo conformada por 200 segundos molares mandibulares permanentes de una población peruana, observadas en tomografías cone beam, donde se registró la presencia del conducto en C, su configuración según la clasificación de Fan y el sexo del paciente. Resultados: La prevalencia de la configuración radicular en forma de C en segundos molares inferiores fue del 65,5 por ciento; según la Clasificación de Fan se observó mayor prevalencia en el tercio cervical del conducto radicular el tipo C1 con 85,7 por ciento; en el tercio medio el tipo C2 con 42,9 por ciento; a nivel apical fue el tipo C3C con 72,1 por ciento; según el sexo, el 65,2 por ciento de los conductos en C correspondió al femenino. Conclusión: La prevalencia de los conductos en C de los segundos molares mandibulares evaluados en tomografías de haz cónico fue de 65,5 por ciento con mayor predominio en el sexo femenino. La evaluación tomográfica permite una mejor identificación y configuración interna de los conductos radiculares(AU)
Introduction: Adequate knowledge of the configuration of root canals is fundamental in endodontics; tomographic evaluation allows a correct assessment of their radicular arrangement. Objective: To determine the prevalence of C-shaped canals in mandibular second molars, evaluated by cone beam tomography. Methods: A descriptive and cross-sectional study was carried out; the sample consisted of 200 permanent mandibular second molars from a Peruvian population, observed in cone beam tomography, where the presence of the C-shaped canal, its configuration according to Fan's classification and the patient's gender were recorded. Results: The prevalence of the C-shaped root canal configuration in lower second molars was 65.5 percent; according to the Fan classification, the highest prevalence was observed in the cervical third of the root canal, type C1 with 85.7 percent; in the middle third, type C2 with 42.9 percent; at the apical level it was type C3C with 72.1 percent; according to gender, 65.2 percent of the C-shaped canals corresponded to females. Conclusion: The prevalence of C-shaped canals in mandibular second molars evaluated in cone beam tomography was 65.5% with a higher predominance in the female gender. The tomographic evaluation allows a better identification and internal configuration of the root canals(AU)

Objectives@#COVID-19 exacerbates the long-standing, low-grade chronic inflammation observed in diabetes leading to heightened insulin resistance and hyperglycemia. Mortality increases with hyperglycemia and poor glycemic variability, hence, this study aims to identify the predictors associated with poor glycemic control and increased glucose variability among patients with COVID-19 and Type 2 Diabetes Mellitus (T2DM).@*Methodology@#A retrospective chart review of 109 patients with moderate to severe COVID-19 and T2DM admitted from March 2020 to June 2021 was done. Logistic regression was done to determine predictors for hyperglycemia and poor variability.@*Results@#Of the 109 patients, 78% had hyperglycemia and poor variability and 22% had no poor outcomes. Chronic kidney disease (eOR 2.83, CI [1.07-7.46], p=0.035) was associated with increased glycemic variability. In contrast, increasing eGFR level (eOR 0.97, CI [0.96-0.99], p=0.004) was associated with less likelihood of increased variability. Hs-CRP (eOR 1.01, CI [1.00-1.01], p=0.011), HbA1c (eOR 1.86, CI [1.23-2.82], p=0.003), severe COVID-19 (eOR 8.91, CI [1.77-44.94], p=0.008) and critical COVID-19 (eOR 4.42, CI [1.65-11.75], p=0.003) were associated with hyperglycemia. Steroid use (eOR 71.17, CI [8.53-593.54], p<0.001) showed the strongest association with hyperglycemia.@*Conclusion@#Potential clinical, laboratory and inflammatory profiles were identified as predictors for poor glycemic control and variability outcomes. HbA1c, hs-CRP, and COVID-19 severity are predictors of hyperglycemia. Likewise, chronic kidney disease is a predictor of increased glycemic variability.

Background and Objectives@#Two of the authors, one heterosexual and one homosexual, both voluntarily donated blood to a well-known health institution in the Philippines. As they were filling out the paperwork, one of the authors' attention was called by one of the questions in the form: “Nakipagtalik ka na ba sa iyong kauri?,” which can be literally translated as “Have you had sex with your own kind?”. This erroneously phrased question was the sole question interrogated and problematized in the study.@*Methodology@#Reviews of Standpoint Theory and the methodology associated with it and, in effect, used in the study, formed part of the critique, divided into individual narrations and interpretations by each author. A third co-author, a hematologist, lent her insight on the logistics and issues of phlebotomy. Institutional ethnography was brought to bear on the narratives@*Results and Conclusion@#This three-author collaboration is presented as a claim that an interdisciplinary approach may open new vistas to a phenomenon that has long existed but been ignored. Reviews of Standpoint Theory and curriculum planning for health professionals are recommended.
