ABSTRACT
Pre-pregnancy body mass index (pBMI) is a predictor of gestational weight gain (GWG). However, other factors, such as adipokines and inflammation markers, may also be associated with GWG. The aim of the study was to determine the association of leptin, adiponectin, irisin, and C-reactive protein, with GWG in adolescents. A longitudinal study was conducted from 2018 to 2023 in adolescents with a clinically healthy pregnancy. The assessments included sociodemographic and clinical data, pBMI, percent of body fat, serum concentrations of leptin, adiponectin, irisin, and high-sensitivity C-reactive protein (hsCRP), and total GWG adequacy. Cox regression models were performed, the outcome variables were inadequate and excessive GWG. In 198 participants, being overweight/obesity was marginally associated with a protective effect against inadequate GWG (HR = 0.44, 95%CI = 0.18-1.06), regardless of maternal characteristics and adipokines. Leptin (HR = 1.014, 95%CI = 1.008-1.021), and body fat percent (HR = 1.11, 95%CI = 1.05-1.17) were associated with a higher risk of excessive GWG, independent of other maternal variables such as pBMI, while adiponectin was associated with a lower risk. These findings suggest that, in Mexican adolescents, adipose tissue and its adipokines during pregnancy may play a more significant role in the final GWG than body weight.

OBJECTIVE: To identify the determinants and risks associated with developing hypertension and metabolic syndrome in the first year postpartum in women who experienced preeclampsia. METHODS: A cohort study was conducted, involving women who had experienced preeclampsia (PE) recently. The control group was women with the same characteristics but a healthy pregnancy. The variables analyzed were somatometry, disease history, pre-pregnancy body mass index (Pre-BMI), and Third Adult Treatment Panel updated (ATP III) metabolic syndrome (MS) data (blood pressure, obesity, triglycerides, high-density lipoproteins, and fasting glucose). These variables were measured at 3, 6, and 12 months postpartum. RESULTS: Women with a history of PE exhibited higher systolic and diastolic blood pressure than women without PE. The risk of developing isolated diastolic arterial hypertension at 3 and 12 months of follow-up was two to eight times greater in women with a history of PE. Factors associated with having higher blood pressure levels were preeclampsia, insulin resistance, age, and BMI. Neither the pre-BMI index nor gestational weight gain (GWG) had any effect on blood pressure in any of the three assessments. Women with preeclampsia had a 5- to 8-fold increased risk of developing MS (which could be explained not only by the history of preeclampsia but also by the history of pre-pregnancy obesity). However, PE was not identified as a risk factor at the six-month evaluation and was only explained by pre-pregnancy obesity and overweight. CONCLUSIONS: Obesity and overweight, as well as preeclampsia, were strongly associated with the development of hypertension and metabolic syndrome during the first year following childbirth.
ABSTRACT
Apheresis allows the collection of specific blood components but changes serum calcium (Ca), magnesium (Mg), copper (Cu), zinc (Zn), and hormones involved in bone metabolism due to citrate infusion. We assessed the effect of oral supplementation of calcium, vitamin D, and minerals as pills or an enriched diet before plateletpheresis donation on levels of divalent cations, hormones, and bone turnover markers that may prevent metabolic changes. Methods: Non-randomized controlled study including 134 donors. Serum parathyroid hormone (PTH), Ca, Mg, Zn, Cu, osteocalcin (OC), vitamin D, and type-1 collagen C-terminal telopeptide (CTX-1) levels were measured at baseline and post-procedure. Donors were divided into four groups: supplemented with calcium carbonate and vitamin D (cal + vitd); those receiving calcium, minerals, and vitamin D (cal + vitd + min); those receiving a calcium-rich diet (diet) and a control group (control). Results: PTH levels increased >1-fold, whereas tCa, tMg, Zn, Cu, iCa, iMg, and vitamin D levels decreased immediately after apheresis amongst donors of any group; when these levels were measured two weeks later, donors in the calcium-vitd and cal + vitd + min groups returned to basal values; donors in the cal + vitd + min group were the only group that kept their levels of OC and CTX unchanged at the different study times. Conclusions: Bone turnover markers changes induced by plateletpheresis may be minimized with oral supplementation of calcium, minerals, and vitamin D two days before the procedures.
ABSTRACT
In this work, we studied 217 Mexican subjects divided into six groups with different stages of glucose intolerance: 76 Controls (CO), 54 prediabetes (PRE), 14 T2D no medication (T2D-No-M), 14 T2D with Metformin (T2D-M), 22 T2D with polypharmacy (T2D-P), and 37 T2D with polypharmacy and insulin (T2D-P+I). We aimed to determine differences in the gut microbiota diversity for each condition. At the phylum level, we found that Firmicutes and Bacteroidetes outline major changes in the gut microbiota. The gut bacterial richness and diversity of individuals in the T2D-No-M group were lesser than other groups. Interestingly, we found a significant difference in the beta diversity of the gut microbiota among all groups. Higher abundance was found for Comamonadaceae in PRE, and Sutterella spp. in T2D-No-M. In addition, we found associations of specific microbial taxa with clinical parameters. Finally, we report predicted metabolic pathways of gut microbiota linked to T2D-M and PRE conditions. Collectively, these results indicate that each group has specific predicted metabolic characteristics and gut bacteria populations for each phenotype. The results of this study could be used to define strategies to modulate gut microbiota through noninvasive treatments, such as dietary intervention, probiotics or prebiotics, and to improve glucose tolerance of individuals with prediabetes or T2D.
ABSTRACT
OBJECTIVE: to detect the risk of development of type 2 diabetes in nurses and its relationship with metabolic alterations. METHOD: cross-sectional study, with 155 nurses. The variables investigated were: sociodemographic, body mass index, waist circumference, waist-hip index, lipid profile, basal glycemia and oral glucose tolerance curve. The Finnish Diabetes Risk Score was used to collect data. RESULTS: 155 nurses were included, with an average age of 44 years and 85% were overweight or obese. 52% had a family history of diabetes and 21% had occasional hyperglycemia. With respect to the risk, 59% were identified with moderate and very high risk for type 2 diabetes. Glucose, insulin, glycosylated hemoglobin A1c and insulin resistance increased in parallel to the increased risk for type 2 diabetes, although lipids did not increase. 27% of the sample had impaired fasting glycemia. 15% had glucose intolerance and 5% had type 2 diabetes. CONCLUSION: there was a high detection rate of people at risk for type 2 diabetes (59%) and the high and very high risk score was associated with high levels of glycosylated hemoglobin A1c, glucose, insulin and insulin resistance, but not with lipids.

Obesity is a metabolic disease characterized by low-grade inflammation and accompanied by dyslipidemia and up-regulation of other bioactive molecules, creating a predisposition to endothelial dysfunction and metabolic syndrome. We studied the association between gut microbiota diversity and endothelial dysfunction (EDF) markers in obese Mexican children and adolescents. We examined clinical data including metabolic factors and EDF markers in blood samples. Gut bacterial diversity was characterized by high-throughput sequencing of V3-16S rDNA libraries. Triglycerides, insulin, homeostasis model assessment-insulin resistant (HOMA-IR), leptin, C-reactive protein (CRP), and EDF marker intercellular adhesion molecule 1 (ICAM-1) were significantly higher in obese children and adolescents. Multivariate analysis showed statistically significant positive associations between vascular cell adhesion molecule 1 (VCAM-1) and Veillonellaceae, and between ICAM-1 and Ruminococcus in obese children. In obese adolescents, there was a statistically significant positive association between total cholesterol and Ruminococcus, and between ICAM-1 and Bacteroides. LEfSe analysis showed that the genus Lactobacillus and family Coriobacteriaceae were enriched in children, and genera Collinsella and Prevotella were enriched in obese adolescents. Obese children and adolescents had higher levels of insulin resistance and metabolic syndrome. These results suggest that obese Mexican children and adolescents had increased levels of CRP and a reduction of adiponectin, which causes higher expression of EDF markers, affecting endothelial function and associating with changes in the gut microbiota.

Antecedentes: La enfermedad inducida por el embarazo complica de 5 a 10% de todos los embarazos en la población mexicana y es la principal causa de morbimortalidad materna. Las mujeres con historia de preeclampsia (PE) tienen un riesgo significativo de desarrollar hipertensión y enfermedades cardiovasculares (ECV) años más tarde. En los desórdenes hipertensivos, se propone como un factor etiológico el síndrome metabólico o de resistencia a la insulina. Objetivo: Evaluar el papel de la PE en la evolución clínica, antropométrica y bioquímica durante el primer año posparto. Material y métodos: Se realizó un estudio de cohorte en un grupo de mujeres de 18a 45 años con PE en el último embarazo pertenecientes al Instituto Nacional de Perinatología Isidro Espinosa de los Reyes (INPerIER). Las variables analizadas fueron las características del síndrome metabólico: presión sanguínea, obesidad abdominal, triglicéridos, lipoproteínas de alta densidad y glucosa de ayuno. Se midieron en tres ocasiones durante el primer año posparto, a los tres, seis y 12 meses posparto (MPP). El grupo control estuvo formado por aquellas mujeres con las mismas características, pero con embarazo sin patología. Resultados: El antecedente de PE es un factor que se encuentra con mayor frecuencia relacionado con mayores cifras de tensión arterial en el posparto. La distribución de grasa, glucosa de ayuno, triglicéridos y lipoproteínas de alta densidad (LAD) no fueron factores que cambiaran, por contar con la condición de cursar con PE, tampoco cambiaron con el paso del tiempo.
Introduction: Hypertension induced by pregnancy complicates between 5 to 10% of all pregnancies among Mexican women and represents the principal cause of maternal, fetal and neonatal morbimortality. Woman with a personal history of preeclampsia (PE) have a higher risk to develop further hypertension and cardiovascular disease (CV). Among hypertensive disorders, metabolic syndrome and insulin resistance are suggested as etiologic factors. Objective: To evaluate the role of PE among anthropometric, clinic and biochemical evolution during the first year postpartum. Material and Methods: A cohort study was performed with woman between 18 to 45 years, with a history PE in their last pregnancy who receives attention at the Instituto Nacional de Perinatología (INPerIER). The analyzed variables were the ones that are characteristic of the metabolic syndrome such as blood pressure, abdominal obesity, triglycerides, high density lipoprotein (HDL) and fasting plasma glucose. During the 1st year postpartum, the variables were measured three times, at three, six and 12 months. The control group had the same measurements and also the same characteristics than the other group, except for the presence of PE. Results: In the postpartum period, the history of PE is commonly related with higher blood pressure. Fat distribution, fasting plasma glucose, triglycerides and HDL neither change across time no changed when presence of previous PE.
