Association of vaccine status, reinfections, and risk factors with Long COVID syndrome.

The COVID-19 pandemic had a profound global impact, characterized by a high fatality rate and the emergence of enduring consequences known as Long COVID. Our study sought to determine the prevalence of Long COVID syndrome within a population of Northeastern Mexico, correlating it with patients' comorbidities, number of COVID-19 reinfection, and vaccination status. Employing an observational cross-sectional approach, we administered a comprehensive questionnaire covering medical history, demographics, vaccination status, COVID-related symptoms, and treatment. Our participant cohort included 807 patients, with an average age of 41.5 (SD 13.6) years, and women accounting 59.3% of the cohort. The follow-up was 488 (IQR 456) days. One hundred sixty-eight subjects (20.9%) met Long COVID criteria. Long COVID-19 was more prevalent when subjects had reinfections (p = 0.02) and less frequent when they had a complete vaccination scheme (p = 0.05). Through logistic regression, we found that male gender (OR 0.5, p ≤ 0.001), blood types of AB- (OR 0.48, p = 0.003) and O- (OR 0.27, p ≤ 0.001) in comparison with A+ and two doses of vaccines (OR 0.5, p = 006) to be protective factors against Long COVID; while higher BMI (OR 1.04, p = 0.005) was a risk factor. We saw that the prevalence of Long COVID was different within vaccinated patients and specific blood types, while being female and a higher BMI were associated with an increased risk of having long-COVID.

[Clinical experience with a C-section surgical technique in patients with morbid obesity: a case series]. / Experiencia clínica de una técnica quirúrgica de cesárea para pacientes con obesidad mórbida: serie de casos.

Obesity is a public health challenge that has crossed into the area of reproductive health. An obese pregnant woman has multiple complications before, during, and after pregnancy. Likewise, cesarean section is more difficult and has slower recovery times in this group of patients. This paper proposes a surgical technique adapted to the morbidly obese pregnant patient that aims to reduce cesarean section complications.

La obesidad representa un desafío para la salud pública, que ha atravesado sus fronteras involucrando el área de la salud reproductiva. Una mujer embarazada obesa tiene múltiples complicaciones antes, durante y después del embarazo. El procedimiento quirúrgico de cesárea de igual manera conlleva un mayor índice de dificultad en su procedimiento y recuperación. En este documento se plantea una técnica quirúrgica adaptada al grupo específico de obesidad mórbida, para disminuir dichas complicaciones dentro de una institución pública de salud.

Enfermedad cardiovascular en pacientes con trasplante renal / Markers of thrombosis in patient with thrombophilia

Introducción: la enfermedad cardiovascular constituye una causa importante de morbilidad y mortalidad en el paciente con trasplante renal. Objetivo: conocer la frecuencia de la enfermedad cardiaca en los pacientes con trasplantes renales y su asociación con diferentes factores de riesgo. Métodos: se realizó un estudio descriptivo, transversal que incluyó 63 pacientes con trasplantes, del Instituto de Nefrología, seguidos en consulta de enero a diciembre del 2011. Resultados: de los 63 pacientes estudiados, 48 padecían enfermedad cardiovascular (76,2 por ciento), las más frecuentes fueron la cardiopatía hipertensiva y la disfunción diastólica. Los factores de riesgo que se vieron con más frecuencia fueron la hipertensión arterial, la hiperlipidemia y el hábito de fumar aunque ninguno tuvo significación estadística en su asociación. La frecuencia de enfermedad cardiovascular aumentó con la edad y esto tuvo significación estadística, de igual forma, el tiempo de trasplante y el de hemodiálisis se asociaron con la enfermedad cardiovascular (ECV) con valores de p=0,00 y p=0,05, respectivamente. Conclusiones: la hipertensión arterial y las glomerulopatías constituyeron las principales causas de insuficiencia renal crónica. Hubo alta frecuencia de enfermedad cardiovascular que aumentó con la edad. El tiempo con trasplante renal funcionante se relaciona con la presencia de enfermedad cardiovascular al igual que el tiempo en hemodiálisis previo al trasplante(AU)

Introduction: cardiovascular disease is a major cause of morbidity and mortality in patients with renal transplantation. Objective: to determine the frequency of heart disease in patients with renal transplantation and its association with various risk factors. Methods: a descriptive, cross-sectional study was performed in 63 patients with transplants at Institute of Nephrology. The were followed up in consultation from January to December 2011. Results: out of 63 patients studied, 48 had cardiovascular disease (76.2 percent). hypertensive heart disease and diastolic dysfunction were more frequent. Most frequently risk factors were hypertension, hyperlipidemia and smoking although none was statistically significant in their association. The frequency of cardiovascular disease increased with age and this was statistically significant, similarly, the transplant and hemodialysis times were associated with cardiovascular disease (CVD) with values of p = 0.00 and p = 0.05, respectively. Conclusions: glomerular and hypertension were the main causes of chronic renal failure. There was high incidence of cardiovascular disease, which increases with age. The functioning renal transplant time is associated with the presence of cardiovascular disease as well as the hemodialysis time before transplantation(AU)
