Associations between prenatal serum levels of leptin, IGF-I, and estradiol and adolescent mothers' height gain during and after pregnancy.

Mexico is within the top three Latin American countries with the highest proportion of adolescent pregnancies while being in the lowest ten Latin American countries in terms of height. It is still unclear how much growth in adolescence is affected by pregnancy; therefore, this study was designed to study the association between prenatal serum concentrations of leptin, IGF-I, and estradiol and the increase in the height of a group of pregnant adolescents between the 28th week of gestation to one year postpartum. We conducted a cohort study from 2009 to 2017 in pregnant adolescents in their third trimester of pregnancy receiving prenatal care at Mexico's National Institute of Perinatology. Data on hormones, other covariates, and confounding variables were analyzed through bivariate analysis and then a linear univariate analysis. Our patients were an average of 15.5±1 years and gained an average of 9.5 mm during the study period. A Pearson's correlation showed a positive and significant height increase between height and leptin and IGF-I, and negative between height and estradiol. The general linear model (adjusted by age, bone age, gynecological age, parent's stature, breastfeeding, body fat, energy intake, and BMI) found that leptin and estradiol serum concentrations explained 39.6% of height increase; IGF-I did not have any predictive effect. Leptin and estradiol concentrations in the third trimester of pregnancy are associated with increased height in our group of teenage mothers. No effect association was observed between height and IGF-I concentrations.

La obesidad como factor de riesgo de gravedad por la infección de COVID-19 / Obesity as a risk factor for severity of COVID-19 infection / A obesidade como um fator de risco grave para a infecção por COVID-19

Los nuevos estilos de vida forzados por la pandemia, han mostrado un incremento en la incidencia en los niveles de índice de masa corporal de sobrepeso y obesidad en la población, a su vez estos casos, se visibilizaban más al estar relacionados con casos de gravedad por la enfermedad del COVID-19. Objetivo. Relacionar que el sobrepeso y obesidad, si son factores de riesgo y predicción de situaciones de gravedad por infección del COVID-19. Materiales y métodos. Se realizó un estudio, tipo descriptivo correlacional. Para esta investigación, se tomó muestra poblacional de personal voluntario de 48 personas, principalmente constituido por estudiantes y algunos docentes que pertenecen a la Facultad de Educación de la Universidad Nacional José Faustino Sánchez Carrión. Este personal fue evaluado en dos clínicas ubicadas en ciudades diferentes, la información biométrica y resultados de análisis de sangre, se consultó con personal médico asesor. Luego de un año se realizó una segunda evaluación, mediante una encuesta, para recabar información sobre la respuesta del sistema inmune del personal evaluado, ante una infección COVID-19 si fuera el caso. Se realizó la consulta médica respecto a los resultados obtenidos, sobre la correlación entre la obesidad, como factor de riesgo en el nivel de gravedad de la enfermedad COVID-19. Resultados. Se determinó que 13 personas evaluadas que corresponden: al 27.08% del total, registraron sobrepeso y presentaron clínicas leves o severas ocasionadas por el COVID-19. Conclusiones. Por lo que, este resultado demuestra que en personas con sobrepeso son propensos a padecer diversas enfermedades, esta situación de su comorbilidad, los expone a alto riesgo de llegar a situaciones graves de su salud por la infección del COVID-19.

The new lifestyles forced by the pandemic have shown an increase in the incidence of overweight and obesity body mass index levels in the population, and these cases are more visible because they are related to serious cases of COVID-19 disease. Objective. To relate that overweight and obesity are risk factors and predictors of severity situations due to COVID-19 infection. Materials and methods. A descriptive correlational study was carried out. For this research, a population sample of 48 volunteer personnel was taken, mainly made up of students and some teachers belonging to the Faculty of Education of the Universidad Nacional José Faustino Sánchez Carrión. These personnel were evaluated in two clinics located in different cities; the biometric information and blood test results were consulted with medical advisors. After one year, a second evaluation was carried out by means of a survey to gather information on the response of the immune system of the evaluated personnel to a COVID-19 infection, if applicable. A medical consultation was made regarding the results obtained on the correlation between obesity as a risk factor in the level of severity of COVID-19 disease. Results. It was determined that 13 people evaluated, corresponding to 27.08% of the total, were overweight and presented mild or severe symptoms caused by COVID-19. Conclusions. Therefore, this result shows that overweight people are prone to suffer from various diseases, this situation of their comorbidity, exposes them to high risk of reaching serious health situations due to COVID-19 infection.

Manejo quirúrgico abierto de la disección de aorta abdominal / Open Surgical Management of the Abdominal Aortic Dissection

RESUMEN La disección aórtica ocurre cuando las capas de la pared aortica se separan como resultado de la entrada de sangre a través de un desgarro en la íntima. El promedio reportado para la disección primaria de la aorta abdominal es menor al 2 por ciento, comparado con el de la aorta ascendente (70 por ciento), aorta descendente (20 por ciento) y el arco aórtico (7 por ciento). Se reporta el caso de un paciente masculino de 74 años de edad que inició su padecimiento con dolor lumbar y abdominal súbito e intenso. Se le realizó una angiotomografía que mostró una disección de la aorta abdominal infrarrenal con extensión a ambas arterias iliacas primitivas hasta antes de su bifurcación. Se le realizó un bypass aortobifemoral con injerto bifurcado de Dacron obteniendo un buen resultado posoperatorio. La disección aórtica abdominal primaria es una rara patología que en pacientes sintomáticos se puede tratar mediante la reparación abierta o endovascular, si se decide realizar la técnica abierta se puede realizar la escisión más bypass aortobifemoral obteniendo buenos resultados como en este caso(AU)

ABSTRACT Aortic dissection occurs when the layers of the aortic wall separate as a result of the entry of blood through a tear in the intima. The average figure reported for primary dissection of the abdominal aorta is less than 2 percent, compared with that of the ascending aorta (70 percent), descending aorta (20 percent), and aortic arch (7 percent). We report the case of a 74-year-old male patient who began his disease with sudden and intense abdominal and back pain. An angiotomography was performed that showed a dissection of the infrarenal abdominal aorta with extension to both primitive iliac arteries until before its bifurcation. An aortobifemoral bypass with a bifurcated Dacron graft was performed, obtaining a good postoperative result. Primary abdominal aortic dissection is a rare pathology that, in symptomatic patients, can be treated by open or endovascular repair. If it is decided to perform the open technique, excision can be performed plus aortobifemoral bypass, obtaining good results as in this case(AU)

Efecto de la administración de vitamina K en las complicaciones asociadas con enfermedad hepática crónica terminal / Effect of the administration of vitamin K on the complications associated with end stage liver disease

Resumen ANTECEDENTES La administración de vitamina K se restringe a situaciones, como antídoto de los antagonistas de vitamina K y enfermedad hemorrágica del recién nacido, pero debido a su papel en la hemostasia, su administración se ha extendido al tratamiento de otras enfermedades, como la enfermedad hepática crónica. OBJETIVO Identificar la eficacia de adicionar vitamina K al tratamiento de los pacientes con insuficiencia hepática terminal con algún estado de descompensación. MATERIAL Y MÉTODO Estudio de casos y controles retrospectivo realizado en el periodo 2016-2017 en pacientes con enfermedad hepática crónica estadio Child-Pugh C durante un episodio de descompensación. La vitamina K (bisulfito sódico de menadiona) se administró a dosis de 10 mg vía intramuscular cada 12 h durante tres días. RESULTADOS Se estudiaron 60 pacientes, 30 recibieron vitamina K, en caso de un evento hemorrágico se administró en conjunto terapia de sustitución con plasma fresco congelado y crioprecipitados. La media de edad fue de 60 (25-86) años, todos los casos eran del género masculino. La principal causa de complicación fue la hemorragia (85%). Cinco casos (8.3%) fallecieron por reactivación de la hemorragia. Administrar vitamina K no acortó las pruebas de coagulación (TP, TTPa, INR) ni mostró beneficio en la mortalidad. Sólo la trombosis como la encefalopatía mostró asociación con la mortalidad. CONCLUSIÓN La adición de vitamina K no influye en las complicaciones en pacientes con enfermedad hepática terminal.

Abstract BACKGROUND The administration of vitamin K are restricted to situations such as an antidote for vitamin K antagonists and hemorrhagic disease of the newborn, but due to its role in hemostasis, its use has been extended to other diseases, such as terminal chronic liver disease. OBJECTIVE To identify the efficacy of adding vitamin K to the management of patients with terminal hepatic insufficiency with some state of decompensation. MATERIAL AND METHOD A retrospective case-control study was done between 2016-2017 in patients with Child-Pugh C chronic liver disease during an episode of decompensation. Vitamin K (menadione sodium bisulfite) was administered at a dose of 10 mg intramuscular every 12 h for three days. RESULTS A total of 60 patients were studied, 30 received vitamin K, in the case of a hemorrhagic event, replacement therapy with fresh frozen plasma and cryoprecipitates were administered together. The mean age was 60 (25-86) years; all were male. Hemorrhage (85%) was the main cause of complication. Five cases (8.3%) died due to reactivation of the hemorrhage. The administration of vitamin K did not shorten the coagulation tests (TP, aPTT, INR) nor showed a mortality benefit. Only thrombosis such as encephalopathy showed an association on mortality. CONCLUSION The addition of vitamin K does not influence the complications in patients with terminal liver disease.
