Aim: Gastric diseases are a recent trend in morbidity in México. We aimed to identify most frequent life habits factors as risk for gastritis and colitis occurrence, in a Mexican mestizo population in Chabeklumil, Chiapas. Population: This study was observational, descriptive, transversal and prospective;346 questionnaires were applied to individuals of both genders from 11 years of age, with low income and socio-economic status, after they signed the informed consent. An individual file was created by the nurses in Chabeklumil. The predominant gender in the population was female (56.1%), with a distribution of 166 among adulthood (19 - 59 years of age);among males (43.9%), 133 included adults. Results: We identified the following environmental risk factors to develop gastritis and colitis: long periods of daily fasting > consumption of irritant food and drink > stress, in females;in contrast, males reported alcohol and tobacco consumption > irritant food and drink > long periods of daily fasting > stress. We found statistical differences (P < 0.05) in risk factors between females and males, in drugs and alcohol consumption, fasting, and stress, but not in consumption of irritant foods, nor in colitis and gastritis prevalence. Conclusions: Females are most affected by life habits risk factors for gastritis/colitis, which occurs mainly due to lifestyle and “macho” culture, since women are precluded of a better living standard, they work hard in the field, and start early in the day without consuming a meal, which they eat late in the day once arriving home. People in Chabeklumil eat/drink a lot of irritant food like hot pepper and coffee, which damage the gastrointestinal system leading to gastritis and colitis. Furthermore, men started to consume drugs at early ages, a condition also involved in developing gastritis.

The body mass index (BMI) as a public health tool to predict metabolic syndrome

引用

Open Journal of Preventive Medicine 2012年第1期2卷 59-66页

作者： miguel murguía-romero Rafael Jiménez-Flores Rafael Villalobos-Molina María Isabel Mendoza-Ramos Julia Reyes-Reali Santiago C. Sigrist-Flores Adolfo René Méndez-Cruz Carrera de Médico Cirujano FES Iztacala UNAM Tlalnepantla México

Objective: To analyze the body mass index (BMI) as an indicator of metabolic alterations, including the metabolic syndrome (MetS), at both individual level and public health level. Method: We recruited 3683 undergraduate students (17 - 24 years old) from México City identifying metabolic alterations, including the MetS, and comparing its prevalence by BMI ranges. We applied a sensitivity analysis to define BMI optimal cut-off point values. Results: We found 14.6% of MetS prevalence with a BMI average of 24.2%, and 34.5% of overweight prevalence (BMI ≥ 25). A BMI cut-off point value of 22.5 is suggested as an upper limit of a normal weight condition, only for public health purpose;while at individual level the BMI cut-off point of 25 was corroborated as the upper limit for a normal weight condition. A public health tool to estimate the MetS prevalence based on BMI percentages is proposed, and a study case is presented. Conclusion: BMI fails predicting at individual level both, healthy condition or metabolic alterations, when values are lower than 25. At population level, the BMI is a valuable public health tool to estimate MetS prevalence: based on the prevalence of MetS by BMI ranges of a sample of the population.

Endotoxin-induced alterations of adipose tissue function:a pathway to bovine metabolic stress

引用

Journal of Animal Science and Biotechnology 2024年第4期15卷 1391-1407页

作者： miguel Chirivi G.Andres Contreras Department of Large Animal Clinical Sciences Michigan State UniversityEast LansingMIUSA

During the periparturient period, dairy cows exhibit negative energy balance due to limited appetite and increased energy requirements for lactogenesis. The delicate equilibrium between energy availability and expenditure puts cows in a state of metabolic stress characterized by excessive lipolysis in white adipose tissues(AT), increased production of reactive oxygen species, and immune cell dysfunction. Metabolic stress, especially in AT, increases the risk for metabolic and inflammatory diseases. Around parturition, cows are also susceptible to endotoxemia. Bacterial-derived toxins cause endotoxemia by promoting inflammatory processes and immune cell infiltration in different organs and systems while impacting metabolic function by altering lipolysis, mitochondrial activity, and insulin sensitivity. In dairy cows, endotoxins enter the bloodstream after overcoming the defense mechanisms of the epithelial barriers, particularly during common periparturient conditions such as mastitis, metritis, and pneumonia, or after abrupt changes in the gut microbiome. In the bovine AT, endotoxins induce a pro-inflammatory response and stimulate lipolysis in AT, leading to the release of free fatty acids into the bloodstream. When excessive and protracted, endotoxin-induced lipolysis can impair adipocyte's insulin signaling pathways and lipid synthesis. Endotoxin exposure can also induce oxidative stress in AT through the production of reactive oxygen species by inflammatory cells and other cellular components. This review provides insights into endotoxins' impact on AT function, highlighting the gaps in our knowledge of the mechanisms underlying AT dysfunction, its connection with periparturient cows' disease risk, and the need to develop effective interventions to prevent and treat endotoxemia-related inflammatory conditions in dairy cattle.

Objective: Metabolic Syndrome (MetS) is the leading cause to develop type 2 diabetes worldwide. We examined associations of MetS components early in life, and their use as risk factors of acquiring MetS. Method: We used an international definition of MetS. Subjects were categorized into “Healthy”/“Not Healthy”, altered parameters are low HDL-cholesterol, large waist circumference (WC), hypertriacylglycerolemia, hypertension, and hyperglycemia, in 32 combinations (2^5) with two values (altered/not altered). MetS was identified with three or more altered parameters. Results: A total of 3424 students (ages 17 - 24 years) participated in the survey, and 2475 were “Not Healthy” showing at least 1 parameter altered;from them 49.6% showed low blood HDL either alone or combined, 38.2% had altered waist circumference either alone or combined;while 18.1% showed hypertriacylglycero-lemia either alone or combined. Hypertension and hyperglycemia were the lowest in frequency. Conclusion: We propose that the binomium HDL/ Waist Circumference is the main prevalence factor to develop MetS in the asymptomatic young population, followed by hypertriacylglycerolemia which together define MetS;while hypertension and hyperglycemia seem to occur later in MetS.
