Hepatic steatosis induced by nicotine plus Coca-Cola™ is prevented by nicotinamide riboside (NR).

Introduction: Cigarettes containing nicotine (Nic) are a risk factor for the development of cardiovascular and metabolic diseases. We reported that Nic delivered via injections or e-cigarette vapor led to hepatic steatosis in mice fed with a high-fat diet. High-fructose corn syrup (HFCS) is the main sweetener in sugar-sweetened beverages (SSBs) in the US. Increased consumption of SSBs with HFCS is associated with increased risks of non-alcoholic fatty liver disease (NAFLD). Nicotinamide riboside (NR) increases mitochondrial nicotinamide adenine dinucleotide (NAD+) and protects mice against hepatic steatosis. This study evaluated if Nic plus Coca-Cola™ (Coke) with HFCS can cause hepatic steatosis and that can be protected by NR. Methods: C57BL/6J mice received twice daily intraperitoneal (IP) injections of Nic or saline and were given Coke (HFCS), or Coke with sugar, and NR supplementation for 10 weeks. Results: Our results show that Nic+Coke caused increased caloric intake and induced hepatic steatosis, and the addition of NR prevented these changes. Western blot analysis showed lipogenesis markers were activated (increased cleavage of the sterol regulatory element-binding protein 1 [SREBP1c] and reduction of phospho-Acetyl-CoA Carboxylase [p-ACC]) in the Nic+Coke compared to the Sal+Water group. The hepatic detrimental effects of Nic+Coke were mediated by decreased NAD+ signaling, increased oxidative stress, and mitochondrial damage. NR reduced oxidative stress and prevented mitochondrial damage by restoring protein levels of Sirtuin1 (Sirt1) and peroxisome proliferator-activated receptor coactivator 1-alpha (PGC1) signaling. Conclusion: We conclude that Nic+Coke has an additive effect on producing hepatic steatosis, and NR is protective. This study suggests concern for the development of NAFLD in subjects who consume nicotine and drink SSBs with HFCS.

Utility of a clinical risk scale to predict the requirement of advanced airway management in patients with a diagnosis of deep neck abscess,

Abstract Objectives To analyze the clinical utility of a clinical risk scale to predict the need for advanced airway management in patients with deep neck abscess. Methods Observational, analytical, cross-sectional study. Patients over 18 years old, both genders, with surgical management of a deep neck abscess, between January 1st, 2015 to December 31th, 2021, who were applied the clinical risk scale (https://7-414-5-19.shinyapps.io/ClinicalRiskScore/). The sensitivity, specificity, and predictive values of the scale were calculated based on the identified clinical outcomes. A p < 0.05 was considered significant. Results A sample of 213 patients was obtained, 121 (56.8%) men, of whom 50 (23.5%) required advanced airway management. Dyspnea was the variable with the most statistical weight in our study, (p = 0.001) as well as the multiple spaces involvement, (p = 0.001) the presence of air corpuscles, (p = 0.001) compromise of the retropharyngeal space (p = 0.001) and age greater than 55 years (p = 0.001). Taking these data into account, were found for the clinical risk scale a sensitivity of 97% and a specificity of 65% (p = 0.001, 95% CI 0.856-0.984). Conclusions The clinical risk scale developed to predict advanced airway management in patients with a diagnosis of deep neck abscess may be applicable in our environment with high sensitivity and specificity. Level of evidence: IV.

Resultados maternos y fetales en mujeres embarazadas con enfermedad renal crónica basada en la tasa de filtración glomerular / Maternal And Fetal Outcomes In Pregnant Women With Chronic Kidney Disease Based On Glomerular Filtration Rate

Introducción: el embarazo causa adaptaciones en el riñón, tanto en anatomía como en función, para mantener el entorno extracelular, hemodinámico y hormonal. Sin embargo, estos pueden no llevarse a cabo de manera completamente óptima en presencia de enfermedad renal. El objetivo era estudiar la relación entre la enfermedad renal y los resultados maternos de fetal durante el embarazo, asociado con un rechazo por paciente y/o en relación con el tratamiento especializado. Material y métodos: estudio observacional y retrospectivo en una serie de casos, revisando 134 archivos de pacientes embarazadas con cierto grado de enfermedad renal antes del embarazo. Los resultados maternos registrados fueron: enfermedad hipertensiva durante el embarazo, deterioro renal agudo, necesidad de terapia de sustitución renal y en productos: prematuridad, restricción del crecimiento intrauterino, muerte fetal y aborto espontáneo. Resultados: Resultados maternos: tasa media de filtración glomerular (GFR) de 58.23 ml/min, aumento de peso de 7 kg; La preeclampsia fue diagnosticada en 92 mujeres (55 severas). 46 pacientes mostraron lesión renal aguda, 40 se resolvieron conservativamente; 1 requirió diálisis peritoneal y 15 hemodiálisis (con una decisión retrasada un promedio de un mes por rechazo por paciente y/o pariente). La resolución del embarazo fue por cesárea en 111 pacientes; Nacieron 116 productos antes de las 37 semanas de gestación, con un peso promedio de 1910 g, 94 mostraron restricción del crecimiento intrauterino. Conclusión: la enfermedad renal influyó directamente en el mayor número de resultados adversos maternos y fetales cuando se rechazó la atención médica especializada. Existe una correlación entre el ligero estado de Davison con los estados I, II y IIIA de Kdigo en el análisis de correspondencia

Introduction: Pregnancy causes adaptations in the kidney, both in anatomy and function, to maintain the extracellular, hemodynamic and hormonal environment. However, these may not be carried out completely optimally in the presence of kidney disease. The objective was to study the relation between kidney disease and maternal-fetal outcomes during pregnancy, associated with a rejection by patient and/or relative to specialized treatment. Material and Methods: Observational, retrospective study in a series of cases, reviewing 134 files of pregnant patients with some degree of kidney disease prior to pregnancy. Maternal outcomes recorded were: hypertensive disease during pregnancy, acute renal deterioration, need for renal substitution therapy, and in products: prematurity, restriction of intrauterine growth, fetal death and miscarriage. Results: Maternal outcomes: mean glomerular filtration rate (GFR) of 58.23ml/min, weight gain of 7 kg; preeclampsia was diagnosed in 92 women (55 severe). 46 patients showed acute renal lesion, 40 were conservatively resolved; 1 required peritoneal dialysis and 15 hemodialysis (with decision delayed an average of one month by rejection by patient and/or relative). Resolution of pregnancy was by cesarean in 111 patients; 116 products were born before 37 weeks of gestation, with average weight of 1910 g, 94 showed restriction of intrauterine growth. Conclusion: Kidney disease directly influenced the greater number of adverse maternal and fetal outcomes when specialized medical care was rejected. There is a correlation between slight Davison state with states I, II and IIIa of KDIGO in correspondence analysis.

The lipolysis inhibitor acipimox reverses the cardiac phenotype induced by electronic cigarettes.

Electronic cigarettes (e-cigarettes) are a prevalent alternative to conventional nicotine cigarettes among smokers and people who have never smoked. Increased concentrations of serum free fatty acids (FFAs) are crucial in generating lipotoxicity. We studied the effects of acipimox, an antilipolytic drug, on e-cigarette-induced cardiac dysfunction. C57BL/6J wild-type mice on high fat diet were treated with saline, e-cigarette with 2.4% nicotine [e-cigarette (2.4%)], and e-cigarette (2.4%) plus acipimox for 12 weeks. Fractional shortening and ejection fraction were diminished in mice exposed to e-cigarettes (2.4%) compared with saline and acipimox-treated mice. Mice exposed to e-cigarette (2.4%) had increased circulating levels of inflammatory cytokines and FFAs, which were diminished by acipimox. Gene Set Enrichment Analysis revealed that e-cigarette (2.4%)-treated mice had gene expression changes in the G2/M DNA damage checkpoint pathway that was normalized by acipimox. Accordingly, we showed that acipimox suppressed the nuclear localization of phospho-p53 induced by e-cigarette (2.4%). Additionally, e-cigarette (2.4%) increased the apurinic/apyrimidinic sites, a marker of oxidative DNA damage which was normalized by acipimox. Mice exposed to e-cigarette (2.4%) had increased cardiac Heme oxygenase 1 protein levels and 4-hydroxynonenal (4-HNE). These markers of oxidative stress were decreased by acipimox. Therefore, inhibiting lipolysis with acipimox normalizes the physiological changes induced by e-cigarettes and the associated increase in inflammatory cytokines, oxidative stress, and DNA damage.

Mutations in the bZip region of the CEBPA gene: A novel prognostic factor in patients with acute myeloid leukemia.

BACKGROUND: Hematopoiesis, the process of blood cell formation involves on a complex network of transcription factors. Among them, the CCAAT-enhancer-binding protein alpha (CEBPA) plays a crucial role in maintaining the balance between myeloid proliferation and differentiation. Imbalances in this network can lead to disrupted differentiation and contribute to the development of malignant diseases. AIM: Understanding of disease development and explore potential therapeutic strategies for hematological disorders associated CEPBA gen. MATERIALS AND METHODS: The research involved a comprehensive analysis of CEBPA gene mutations in the context of acute myeloid leukemia (AML). This encompassed a thorough exploration of point mutations and double mutations in AML patients. RESULTS: In the context of acute myeloid leukemia (AML), mutations in the CEBPA gene, especially point mutations, are frequently observed. A significant number of AML patients present with double mutations in CEBPA, which have been linked to a more favorable prognosis in terms of overall survival and event-free survival. These patients also tend to exhibit enhanced responsiveness to treatment. DISCUSSION: Unraveling the intricate interplay of transcription factors, particularly CEBPA, holds significant implications for decoding the mechanisms governing hematopoiesis. This understanding offers a potential avenue for deciphering disease development and devising novel therapeutic strategies for hematological disorders. CONCLUSION: The findings underscore that CEBPA mutations correlate with enhanced overall survival and event-free survival, with relevance to those presenting within the bZip framework. This knowledge may contribute to advancing personalized treatments for hematological conditions.

Fatty Acid Excess Dysregulates CARF to Initiate the Development of Hepatic Steatosis.

CARF (CDKN2AIP) regulates cellular fate in response to various stresses. However, its role in metabolic stress is unknown. We found that fatty livers from mice exhibit low CARF expression. Similarly, overloaded palmitate inhibited CARF expression in HepG2 cells, suggesting that excess fat-induced stress downregulates hepatic CARF. In agreement with this, silencing and overexpressing CARF resulted in higher and lower fat accumulation in HepG2 cells, respectively. Furthermore, CARF overexpression lowered the ectopic palmitate accumulation in HepG2 cells. We were interested in understanding the role of hepatic CARF and underlying mechanisms in the development of NAFLD. Mechanistically, transcriptome analysis revealed that endoplasmic reticulum (ER) stress and oxidative stress pathway genes significantly altered in the absence of CARF. IRE1α, GRP78, and CHOP, markers of ER stress, were increased, and the treatment with TUDCA, an ER stress inhibitor, attenuated fat accumulation in CARF-deficient cells. Moreover, silencing CARF caused a reduction of GPX3 and TRXND3, leading to oxidative stress and apoptotic cell death. Intriguingly, CARF overexpression in HFD-fed mice significantly decreased hepatic steatosis. Furthermore, overexpression of CARF ameliorated the aberrant ER function and oxidative stress caused by fat accumulation. Our results further demonstrated that overexpression of CARF alleviates HFD-induced insulin resistance assessed with ITT and GTT assay. Altogether, we conclude that excess fat-induced reduction of CARF dysregulates ER functions and lipid metabolism leading to hepatic steatosis.

Adverse events in anesthesia: Analysis of claims against anesthesiologists affiliated to an insurance fund in Colombia. Cross-sectional study / Eventos adversos en anestesia: Análisis de las reclamaciones contra anestesiólogos afiliados a un fondo de aseguramiento en Colombia. Estudio de corte transversal

Abstract Introduction: Prevention, identification, analysis and reduction of adverse events (AEs) are all activities designed to increase safety of care in the clinical setting. Closed claims reviews are a strategy that allows to identify patient safety issues. This study analyzes adverse events resulting in malpractice lawsuits against anesthesiologists affiliated to an insurance fund in Colombia between 2013-2019. Objective: To analyze adverse events in closed medicolegal lawsuits against anesthesiologists affiliated to an insurance fund between 2013-2019. Methods: Cross-sectional observational study. Convenience sampling was used, including all closed claims in which anesthesiologists affiliated to an insurance fund in Colombia were sued during the observation period. Variables associated with the occurrence of AEs were analyzed. Results: Overall, 71 claims were analyzed, of which 33.5% were due to anesthesia-related AEs. Adverse events were found more frequently among ASA I-II patients (78.9%), and in surgical procedures (95.8%). The highest number of adverse events occurred in plastic surgery (29.6%); the event with the highest proportion was patient death (43.7%). Flaws in clinical records and failure to comply with the standards were found in a substantial number of cases. Conclusions: When compared with a previously published study in the same population, an increase in ethical, disciplinary and administrative claims was found, driven by events not directly related to anesthesia. Most of the anesthesia-related events occurred in the operating room during surgical procedures in patients and procedures categorized as low risk, and most of them were preventable.

Resumen Introducción: La prevención, identificación, análisis y reducción de los eventos adversos (EA), son actividades direccionadas a incrementar la seguridad de la atención en el entorno clínico. El estudio de los casos cerrados es una estrategia que permite identificar problemas relacionados con la seguridad del paciente. En este estudio se analizan eventos adversos conducentes a procesos medicolegales cerrados contra anestesiólogos afiliados a un fondo de aseguramiento en Colombia entre 2013-2019. Objetivo: Analizar los eventos adversos en procesos medicolegales cerrados de anestesiólogos afiliados a un fondo de aseguramiento entre 2013-2019. Métodos: Estudio observacional de corte transversal. Se analizó una muestra a conveniencia en la que se incluyeron todos los casos cerrados en los que anestesiólogos afiliados a un fondo de aseguramiento en Colombia fueron objeto de reclamaciones en el período de observación. Se analizaron variables relacionadas con la presentación del EA. Resultados: Se analizaron 71 reclamaciones, de las cuales el 33,5 % fueron por EA relacionado con anestesia. Los eventos adversos se encontraron con mayor frecuencia en pacientes ASA I-II (78,9 %), y en procedimientos quirúrgicos (95,8 %). El mayor número de eventos adversos se presentó en cirugía plástica (29,6 %); el evento de mayor proporción fue el fallecimiento del paciente (43,7 %). En un importante número de casos se demostró fallos en el registro de la historia clínica e incumplimiento de normas. Conclusiones: En relación con un estudio publicado previamente en la misma población, se encuentra un incremento en los procesos éticos, disciplinarios y administrativos, motivados por eventos sin una relación directa con el acto anestésico. La mayoría de eventos adversos relacionados con anestesia se presentan en procedimientos quirúrgicos, en salas de cirugía, en pacientes y procedimientos catalogados como de bajo riesgo, y son en su mayoría prevenibles.

Transient gestational hypothyroxinemia accelerates and enhances ulcerative colitis-like disorder in the male offspring.

Introduction: Gestational hypothyroxinemia (HTX) is a condition that occurs frequently at the beginning of pregnancy, and it correlates with cognitive impairment, autism, and attentional deficit in the offspring. Evidence in animal models suggests that gestational HTX can increase the susceptibility of the offspring to develop strong inflammation in immune-mediated inflammatory diseases. Ulcerative colitis (UC) is a frequent inflammatory bowel disease with unknown causes. Therefore, the intensity of ulcerative colitis-like disorder (UCLD) and the cellular and molecular factors involved in proinflammatory or anti-inflammatory responses were analyzed in the offspring gestated in HTX (HTX-offspring) and compared with the offspring gestated in euthyroidism (Control-offspring). Methods: Gestational HTX was induced by the administration of 2-mercapto-1-methylimidazole in drinking water to pregnant mice during E10-E14. The HTX-offspring were induced with UCLD by the acute administration of dextran sodium sulfate (DSS). The score of UCLD symptomatology was registered every day, and colon histopathology, immune cells, and molecular factors involved in the inflammatory or anti-inflammatory response were analyzed on day 6 of DSS treatment. Results: The HTX-offspring displayed earlier UCLD pathological symptoms compared with the Control-offspring. After 6 days of DSS treatment, the HTX-offspring almost doubled the score of the Control-offspring. The histopathological analyses of the colon samples showed signs of inflammation at the distal and medial colon for both the HTX-offspring and Control-offspring. However, significantly more inflammatory features were detected in the proximal colon of the HTX-offspring induced with UCLD compared with the Control-offspring induced with UCLD. Significantly reduced mRNA contents encoding for protective molecules like glutamate-cysteine ligase catalytic subunit (GCLC) and mucin-2 (MUC-2) were found in the colon of the HTX-offspring as compared with the Control-offspring. Higher percentages of Th17 lymphocytes were detected in the colon tissues of the HTX-offspring induced or not with UCLD as compared with the Control-offspring. Discussion: Gestational HTX accelerates the onset and increases the intensity of UCLD in the offspring. The low expression of MUC-2 and GCLC together with high levels of Th17 Lymphocytes in the colon tissue suggests that the HTX-offspring has molecular and cellular features that favor inflammation and tissue damage. These results are important evidence to be aware of the impact of gestational HTX as a risk factor for UCLD development in offspring.

Suicide in Colombian anesthesiologists. National survey study / Suicidio en anestesiólogos colombianos. Estudio de encuesta nacional

Abstract Introduction The risk of suicide among anesthesiologists seems to be higher than in other areas of specialization, probably because of the significant stress associated with this specialty, easy access to strong medications and the profound knowledge about the use of these drugs. There is a poor knowledge about the impact of suicide on anesthesiologists in Colombia and the resources available to deal with this situation are limited. Objective This survey is intended to indirectly identify the frequency of suicide among the Colombian anesthesiologists and the experiences associated with the suicide of a colleague. Methods Observational, cross-sectional study based on a survey administered to all the anesthesiologists members of the Colombian Society of Anesthesiology and Resuscitation (S.C.A.R.E.), at a national scale. Results 403 anesthesiologists completed the survey. Eighty (19.8 %) of the respondents said they were aware of the death of at least one colleague that committed suicide. Most of them are male anesthesiologists or intensivists, and the age group with the highest rate of reports is between 25 - 29 years old in males. The primary causal mechanism was opioid overdose (58.5 %). Conclusions In an indirect characterization of suicide among Colombian anesthesiologists, 99 suicide reports were identified corresponding to 80 anesthesiologists. Suicide is preventable and the worksite should provide the support mechanisms required to identify occupational stress, drug dependence, depression and suicide.

Resumen Introducción: El riesgo de suicidio entre anestesiólogos parece ser mayor que el que se presenta en otras especialidades, posiblemente debido al elevado estrés asociado con la especialidad, al fácil acceso a medicamentos potentes y al conocimiento íntimo de cómo usarlos. En Colombia poco se sabe sobre el impacto del suicidio de un colega en un departamento de anestesia y los recursos disponibles para afrontar esta situación. Objetivo: Con esta encuesta se buscó identificar de manera indirecta la frecuencia de suicidio entre anestesiólogos colombianos y las experiencias relacionadas con el suicidio de un colega. Métodos: Estudio observacional de corte transversal de tipo encuesta aplicada a todos los anestesiólogos afiliados a la Sociedad Colombiana de Anestesiología y Reanimación (S.C.A.R.E.) a escala nacional. Resultados: Se obtuvo respuesta de 403 anestesiólogos. Ochenta (19,8 %) participantes indicaron tener conocimiento de la muerte por suicidio de al menos un colega. La mayoría corresponden a anestesiólogos o intensivistas de sexo masculino, y el grupo etario con mayor número de reportes es el de 25 a 29 años para el sexo masculino. El principal mecanismo causal identificado fue la intoxicación por opioides (58,5 %). Conclusiones: En una caracterización indirecta del suicidio en anestesiólogos colombianos se encontraron 99 informes de suicidio reportados por 80 anestesiólogos. El suicidio es prevenible, en los sitios de trabajo deben existir los mecanismos de apoyo para la identificación del estrés laboral, la farmacodependencia, la depresión y el suicidio.

Factores asociados al cumplimiento de las recomendaciones de actividad física de la Organización Mundial de la Salud, en los adultos de Antioquia - Colombia

Objetivo: Describir los factores asociados al cumplimiento de las recomendaciones de actividad física (AF) de la Organización Mundial de la Salud, en los adultos de Antioquia. Metodología: Se realizó un análisis transversal de la base de datos del "Perfil alimentario y nutricional de Antioquia". La AF se indagó en 2757 adultos (18-64 años), utilizando el "Cuestionario mundial de actividad física" de la Organización Mundial de la Salud. Se hicieron análisis bivariados y multivariados, explorando la relación de variables socioeconómicas, demográficas y de estado nutricional, con el cumplimiento de las recomendaciones de AF. Resultados: Se observó una mayor prevalencia de cumplimiento de las recomendaciones de AF en hombres que mujeres (60,8 vs. 48,0 %; p< 0,001) y en adultos jóvenes (18-29 años) que en mayores de 29 años (66,8 vs. 49,3 %; p< 0,001). Además, se presentó más alta proporción de cumplimiento de las recomendaciones de AF en personas de mayor estrato socioeconómico, mayor nivel educativo y residentes del área urbana. Ser mujer, pertenecer al estrato socioeconómico 1, poseer secundaria o un nivel de educación inferior, y tener como ocupación oficios del hogar se asociaron con una probabilidad menor de cumplir las recomendaciones de AF; por el contrario, ser una persona joven se asocia con un mayor cumplimiento. Conclusión: Son evidentes las desigualdades en el cumplimiento de las recomendaciones de AF por los adultos de Antioquia. Se deben priorizar las mujeres, las personas mayores de 30 años, de bajo estrato socioeconómico y de bajo nivel educativo en los planes y programas orientados a promover la práctica de la AF en el departamento.

Objective: To describe the factors associated with adherence to the World Health Organization's physical activity (PA) recommendations in adults from Antioquia-Colombia. Methodology: A cross-sectional analysis of the database of the "Food and nutritional Profile of Antioquia" was carried out. PA was inquired in 2,757 adults (18-64-year-olds), using the World Health Organization's "Global Physical Activity Questionnaire". Bivariate and multivariate analyses were performed, exploring the relationship between socioeconomic, demographic and nutritional status variables and adherence to PA recommendations. Results: A higher prevalence of adherence to PA recommendations was observed in men compared to women (60.8 vs. 48.0 %; p < 0.001) and in young adults (18-29) compared to in adults older than 29 years of age (66.8 vs. 49.3 %; p < 0.001). In addition, adherence to PA recommendations was higher in people with high socioeconomic status, a high educational level and residents of urban areas. Being a woman, belonging to socioeconomic stratum 1, having high school or a lower level of education, and having as an occupation household chores were associated with a lower probability of adherence to PA recommendations; while being young is associated with greater adherence. Conclusion: Inequalities in adherence to FA recommendations by adults in Antioquia are evident. Women and people over 30 years of age with low socioeconomic status and low educational levels should be prioritized in plans and programs aimed at promoting the practice of PA in the department.

Resumen Objetivo: describir las prácticas alimentarias de 50 familias afrodescendientes con niños y/o niñas de primera infancia que asisten a un Centro de Desarrollo Infantil (CDI) en el Oriente de Cali. Materiales y métodos: Estudio cuantitativo, descriptivo y de corte transversal. Se aplicó un cuestionario a 50 cuidadores de niños o niñas que asistieron al CDI Potrero Grande del oriente de Cali. El cuestionario fue estructurado con preguntas de múltiple elección con base en tres ejes de la seguridad alimentaria: acceso, consumo e inocuidad; adicionalmente un cuestionario de frecuencia de consumo de alimentos. Resultados: 70 % se autorreconoció como afrodescendiente, 63 % procedía principalmente de la costa del sur occidente colombiano, con nivel educativo básico. El 87,5 % se dedicaba exclusivamente al hogar. En el 85 % de los hogares la madre es la encargada de preparar los alimentos, el aporte de proteína animal del 70 % de los hogares, proviene principalmente del huevo cuyo consumo fue diario, el 94 % de las madres expresaron que sus familias nunca consumieron brócoli, coliflor, alverja verde, espinacas, ullucos, repollo y el 95 % de las personas refirieron que se lavan las manos antes de preparar los alimentos. Conclusiones: la dieta no es variada y se basa en alimentos fuentes de carbohidratos principalmente el arroz, papa y los plátanos verdes y maduros, que se consumen cocidos y fritos, al igual que los alimentos fuentes de proteína. El análisis de la ingesta sugiere que no se consumen alimentos característicos del lugar de procedencia como los pescados y/o mariscos.

Abstract Objective: To describe the eating practices of 50 Afro-descendant families with early childhood kids who attend a Child Development Center -CDC- in eastern Cali. Materials and methods: Quantitative, descriptive, and crosssectional study. A questionnaire was applied to 50 caregivers of children who attended the CDI Potrero Grande in eastern Cali. The questionnaire was structured with multiple choice questions based on three axes of food security: access, consumption and safety. Additionally, a food consumption frequency questionnaire was applied. Results: Seventy percent of the participants self-recognized as Afro-descendant, 63% came mainly from the southwestern coast of Colombia with a basic educational level, and 87.5% were dedicated exclusively to the home. The mother was in charge of preparing the food in 85% of the homes. Animal protein contribution of 70% of the homes comes mainly from eggs with daily consumption. A total of 94% of the mothers expressed that their families never consumed broccoli, cauliflower, green peas, spinach, manioc or cabbage and 95% of the people reported that they washed their hands before preparing food. Conclusions: The diet is not varied and is based on carbohydrate source food mainly rice, potatoes and green and ripe bananas which are consumed boiled and fried, as well as protein sources. The analysis of the intake suggests that characteristic foods of the place of origin such as fish and/ or shellfish are not consumed.

Electronic Cigarette Use and the Risk of Cardiovascular Diseases.

Electronic cigarettes or e-cigarettes are the most frequently used tobacco product among adolescents. Despite the widespread use of e-cigarettes and the known detrimental cardiac consequences of nicotine, the effects of e-cigarettes on the cardiovascular system are not well-known. Several in vitro and in vivo studies delineating the mechanisms of the impact of e-cigarettes on the cardiovascular system have been published. These include mechanisms associated with nicotine or other components of the aerosol or thermal degradation products of e-cigarettes. The increased hyperlipidemia, sympathetic dominance, endothelial dysfunction, DNA damage, and macrophage activation are prominent effects of e-cigarettes. Additionally, oxidative stress and inflammation are unifying mechanisms at many levels of the cardiovascular impairment induced by e-cigarette exposure. This review outlines the contribution of e-cigarettes in the development of cardiovascular diseases and their molecular underpinnings.

Usefulness of Computed Tomography Angiography in the Preoperative Workup of Patients With Colorectal Cancer.

OBJECTIVES: The objective of this study is to analyze the main patterns of branching of the inferior mesenteric artery (IMA) and to determine if your knowledge changes the surgical strategy in the colorectal cancer. METHODS: This retrospective study included 63 patients with cancer of the sigmoid or rectum. We assessed the patterns of IMA in 3 subtypes: type A (independent left colic artery [LCA]), type B (LCA and sigmoid artery arising in a common trunk) and type C (LCA, sigmoid artery, and superior rectal artery with a common origin). Colorectal surgeons evaluated how the vascular map changed the type of IMA ligation. RESULTS: Inferior mesenteric artery branching was classified as type A in 55.6% patients, type B in 23.8%, and type C in 20.6%. Knowledge of the vascular map changed the type of ligation from high to low in 20 of the 50 patients who were candidates for surgery. The change was possible in tumors located in the sigmoid colon and the rectosigmoid junction with the type A or B branching. CONCLUSIONS: Preoperative Multidetector Computed Tomography angiography can define the pattern of IMA branching. Based on this information, a low ligation can be performed in tumors located in sigmoid colon and rectosigmoid junction with IMA branching types A and B.

Supervivencia del paciente trasplantado y del injerto renal en una cohorte retrospectiva en México / Transplant patient and kidney graft survival in a retrospective cohort in Mexico

Introducción: el conocimiento de la funcionalidad del injerto y la supervivencia del paciente es fundamental para valorar el éxito del trasplante renal. Objetivo: determinar la supervivencia de los pacientes trasplantados por tipo de donante y la funcionalidad de los injertos renales en una cohorte en México. Material y métodos: cohorte de trasplante renal de 2013 a 2017 en México. Se analizaron 790 pacientes seguidos por un año para valorar la supervivencia de los pacientes trasplantados por tipo de donante y la funcionalidad de los injertos renales. Para ello se usaron medidas de tendencia central y dispersión, así como tablas de supervivencia de Kaplan-Meier con SPSS, versión 25. Resultados: de los 790 pacientes, 518 fueron de donante vivo (65.56%) con supervivencia del paciente de 97.88% y de funcionalidad del injerto de 93.24% a 12 meses de seguimiento; 272 pacientes recibieron el injerto de donante fallecido con supervivencia del paciente de 91.18% y funcionalidad del injerto renal de 84.19%. Conclusiones: aún existe una diferencia de casi 5% en la supervivencia del paciente receptor de un donante vivo en referencia con un donante fallecido. Para la funcionalidad del injerto renal esta diferencia es > 7%. La donación cadavérica ha aumentado; sin embargo, incluso en cifras bajas es de aproximadamente el 35% en México

Background: Knowledge of the functionality of the graft and patient survival is essential to assess the success of kidney transplantation. Objective: To determine the survival of transplanted patients by type of donor and the functionality of kidney grafts in a cohort in Mexico. Material and methods: Kidney transplant cohort from 2013 to 2017 in Mexico. 790 patients followed up for one year were analyzed to assess the survival of transplanted patients by type of donor and the functionality of kidney grafts. For this, measures of central tendency and dispersion were used, as well as Kaplan-Meier survival tables with SPSS, version 25. Results: Out of the 790 patients, 518 were from living donors (65.56%) with patient survival of 97.88% and graft function of 93.24% at 12 months of follow-up; 272 patients received the graft from a deceased donor with patient survival of 91.18% and renal graft function of 84.19%. Conclusions: There is still a difference of almost 5% in the survival of the recipient patient from a living donor compared to a deceased donor. For the functionality of the kidney graft, this difference is > 7%. Cadaveric donation has increased; however, even at low figures is of approximately 35% in Mexico

Angiotensin-(1-7) Prevents Lipopolysaccharide-Induced Autophagy via the Mas Receptor in Skeletal Muscle.

Skeletal muscle atrophy, which occurs in lipopolysaccharide (LPS)-induced sepsis, causes a severe muscle function reduction. The increased autophagy contributes to sepsis-induced skeletal muscle atrophy in a model of LPS injection, increasing LC3II/LC3I ratio, autophagy flux, and autophagosomes. Angiotensin-(1-7) (Ang-(1-7)) has anti-atrophic effects via the Mas receptor in skeletal muscle. However, the impact of Ang-(1-7) on LPS-induced autophagy is unknown. In this study, we determined the effect of Ang-(1-7) on sepsis-induced muscle autophagy. C57BL6 wild-type (WT) mice and mice lacking the Mas receptor (KO Mas) were injected with LPS together with the systemic administration of Ang-(1-7) to determine autophagy in skeletal muscle. We also evaluated autophagy and p38 and c-Jun N-terminal kinase (JNK)activation. Our results show that Ang-(1-7) prevents LPS-induced autophagy in the diaphragm, tibialis anterior, and gastrocnemius of WT mice, which is demonstrated by a decrease in the LC3II/LC3I ratio and mRNA levels of lc3b and ctsl. This effect was lost in KO Mas mice, suggesting the role of the Mas receptor. The results in C2C12 cells show that Ang-(1-7) reduces several LPS-dependent effects, such as autophagy (LC3II/LC3I ratio, autophagic flux, and autophagosomes), activation of p38 and JNK, B-cell lymphoma-2 (BCL2) phosphorylation, and disassembly of the Beclin1/BCL2 complex. In conclusion, Ang-(1-7)/Mas receptor reduces LPS-induced autophagy in skeletal muscle. In vitro assays indicate that Ang-(1-7) prevents LPS-induced autophagy and modifies the MAPK signaling and the disassembly of a complex involved at the beginning of autophagy.

Behavior of Calcium, Phosphorus, and Parathormone Before Transplantation and in Months 1, 3, 6, 9, and 12 After Transplantation.

BACKGROUND: Bone mineral disease after transplantation persists and is an issue that must be addressed owing to the cardiovascular impact it presents. The objective of this study is to present the behavior of calcium, phosphorus, and parathormone (PTH) before renal transplantation (RT) and throughout the 12 months after transplant surgery. METHODS: A longitudinal observational study of RT patients was performed from 2013 to 2017 in 2 renal transplant units in Mexico. In total, 1009 records of patients with RT were analyzed. Calcium, phosphorus, and PTH levels were studied before transplantation and for 12 months after. Central tendency and dispersion were measured, the difference of means was established with chi square or student t tests, and the significant value of P was set at <.05. We also used the SPSS statistical package, version 25. RESULTS: Phosphorus had a median pre-RT of 5.73, which decreased to 2.8 in the first month post-transplant and then increased to 3.41 at 12 months post-RT. The median PTH, on the other hand, started at 420.60 and decreased to 67.45. Calcium began at 9.04 and hit a plateau of 9.58 during month 12 after the surgical event. CONCLUSIONS: Of the 3 biochemical parameters evaluated, phosphorus was the one that most corrected itself after transplantation. Despite a tendency toward hypophosphatemia in the first month after transplantation, it began to normalize from month 6 on. Meanwhile, calcium was the biochemical value that changed the least after transplantation.

[A historical view of breast implants: Controversy on silicones and breast implant associated -anaplastic large cell lymphoma]. / Seins à dessein. Une histoire d' implants mammaires : controverses autour de la silicone et du lymphome anaplasique a grandes cellules-associe implants mammaires.

Since the dawn of breast implantation back in the sixties, five generations of breast implants have tried to provide the most natural-looking results while striving to eliminate the risk of unpleasant ruptures or capsular contractures. National Health regulators (i.e. the FDA in USA and ANSM in France) have had an "after the facts" reaction, which led to a so-called "dirty war" among producers in the form of a 1992 Silicone's Moratorium (after suspicions of associated cancer or immune-related disorders) all this under the rigid oversight of a FDA director, who seemed more sensible to media scandal than scientific data. After more than a decade of consistent scientific evidence, the interdiction was finally ended in France in 2001 and in the USA in 2006, however the scandals resurfaced again in 2011 after a proven fraud on the "PIP - affair" and most recently with "breast implant associated - anaplastic large cell lymphoma", an extremely serious and rare pathology, treated only by surgical means, until further research. We describe also a chronology on the way the FDA finally recognized this dramatic complication.
