The aim of this study was to examine the relationship between the L55M and Q192R paraoxonase (PON1) polymorphisms and obesity in a population of adult Mexican workers. The study population included 127 adult individuals from the Universidad Autónoma del Estado de Morelos, ranging in age from 20 to 56 years and representing both sexes. Based on body mass index, 63 individuals were classified as obese and 64 as normal weight. The PON1-Q192R and PON1-L55M polymorphisms were determined by restriction fragment length polymorphism PCR analysis. Both arylesterase and paraoxonase activity levels were similar in both groups, whereas systolic pressure, triglyceride, total cholesterol, low-density lipoprotein cholesterol, very-low-density lipoprotein cholesterol, glucose, and insulin levels were higher in the obese group than in the normal-weight group (P < 0.05). An exception was the high-density lipoprotein cholesterol (HDL-C) levels, which were lower in the obese group (P < 0.05). Although the PON1-Q192R polymorphism was not associated with either group, the frequency of the homozygous L genotype for the PON1-L55M polymorphism was higher in the obese group than in the normal-weight group (P < 0.05). In conclusion, this study established a positive association between the PON1-L55M homozygous L genotype and obesity.

Human immunodeficiency virus (HIV) infection has continued to be the subject of study since its discovery nearly 40 years ago. Significant advances in research and intake of antiretroviral therapy (ART) have slowed the progression and appearance of the disease symptoms and the incidence of concomitant diseases, which are the leading cause of death in HIV+ persons. However, the prolongation of ART is closely related to chronic degenerative diseases and pathologies caused by oxidative stress (OS) and alterations in lipid metabolism (increased cholesterol levels), both of which are conditions of ART. Therefore, recent research focuses on using natural therapies to diminish the effects of ART and HIV infection: regulating lipid metabolism and reducing OS status. The present review summarizes current information on OS and cholesterol metabolism in HIV+ persons and how the consumption of certain phytochemicals can modulate these. For this purpose, MEDLINE and SCOPUS databases were consulted to identify publications investigating HIV disease and natural therapies and their associated effects.

ObjectiveTo analyse the most frequent self-reported adverse reactions (ARs), the durability and the causes of antiretrovirals (ARVs) regimens change, concomitant treatments and drug interactions related to the use of ARVs in a group of people living with HIV in Cuernavaca, Morelos, Mexico.Materials and methodsCross-sectional study conducted in a clinic specialising in HIV ‘CAPASITS-Cuernavaca’ in Mexico from February to June 2015. People who wanted to participate were given a questionnaire on demographic characteristics, adherence, concomitant treatments and ARs. To understand the clinical variables, the clinical records were reviewed. Quantitative variables were compared using Student’s t-test for normal data and the Mann-Whitney U test for non-normal data. For comparisons between categorical variables, the χ2 test was used. All tests used a significance level of 0.05.ResultsA total of 96 people participated, and 218 ARs (mean= 2.3±1.9) were found. The most frequently encountered ARs were dizziness (53.1%), insomnia (21.9%) and lucid dreams (17.7%). Twenty-three people (24%) were polymedicated, and 18 potential interactions were detected in 12 people.ConclusionsThe results suggest that a thorough analysis of the possible drug interactions should be performed for polymedicated people on ARV treatment and that a protocol should be designed for the monitoring and management of AR to ensure a good adherence to ARV treatment.

Multisystem inflammatory syndrome in children (MIS-C) has been widely reported in some children diagnosed with SARS-CoV-2. Clinical signs of MIS-C are manifested at 2 to 4 weeks after SARS-CoV-2 infection, where elevated biomarkers of inflammation and cardiac dysfunction are the hallmark of this syndrome when infection or exposure to SARS-CoV-2 has been confirmed. However, after two years of acknowledgment, MIS-C treatment is still under research to reach safety and effectiveness in the acute phase in children. Therefore, in this review, we discuss the potential use of natural compounds with antioxidant and anti-inflammatory effects to reduce collateral damage caused by hyperinflammation in MIS-C pathology for new research in treatment and interventions.

This study establishes a positive association of BuChE activity with nutritional status and serum TG.

Introducción. La interpretación médica de los datos de laboratorio clínico resulta ser un proceso fundamental para las decisiones clínicas sobre el paciente y se basan en la comparación de los resultados obtenidos frente al intervalo de referencia calculado dentro de la misma población considerada de referencia. Objetivo. Determinar los intervalos de referencia del perfil de lípidos en una población de trabajadores y estudiantes de la Universidad Autónoma del Estado de Morelos (UAEM), México. Materiales y Métodos. Se incluyeron 142 participantes sanos de entre 20 y 45 años; se determinaron las concentraciones de colesterol total, triglicéridos, HDL-colesterol y LDL-colesterol, mediante técnicas enzimáticas de punto final. Los intervalos de referencias se establecieron con base en métodos no paramétricos, dentro del percentil 2.5% y 97.5%. Resultados. Se obtuvieron los siguientes intervalos de referencia: colesterol total 90.0-208.3 mg/ dL (2.4-5.4 mmol/L); triglicéridos 40.7-215.8 mg/ dL (0.46-2.5 mmol/L); HDL-colesterol 26.0-74.9 mg/dL (0.68-1.9 mmol/L) y LDL-colesterol 31.4- 126.7 mg/dL (0.82-3.3 mmol/L). Conclusiones. Al comparar nuestros datos con otras poblaciones, encontramos que los resultados son muy semejantes y recomendamos el uso de estos valores para la interpretación clínica de la población universitaria del Estado de Morelos, donde la alimentación, la genética y los factores ambientales son característicos de esta población.
