RESUMO

BACKGROUND AND AIMS: In recent years, scientific interest in triglyceride-rich lipoproteins (TRL) and remnant cholesterol has increased, focusing on the evidence that these lipoproteins are a causal factor for developing atherosclerotic cardiovascular disease (ASCVD). Furthermore, a high remnant concentration (>38 mg/dL) has been associated with several non-cardiovascular risks. We aimed in this study to describe the percentile distribution of remnant cholesterol. Additionally, we evaluated the association between remnant cholesterol plasma concentration and epidemiologically relevant cardio-metabolic outcomes such as hypertension, type 2 diabetes (T2D), and ASCVD. METHODS: We analyzed data from 9,591 adults from the National Survey of Health and Nutrition (ENSANUT) 2018 with fasting blood samples and complete medical history questionnaires. We built multivariate models to evaluate the association between chronic diseases and blood remnant concentration. To compare our 2018-sub-sample against a population reference, we used the NHANES (2005-2014) publicly available datasets by ethnicity. RESULTS: Remnants were independently associated with cardiovascular risk, diabetes, hypertension, obesity, and metabolic syndrome. For all outcomes, the blood remnant concentration was a stronger predictor than LDL. At all deciles, the blood remnant concentration was higher in ENSANUT-2018. CONCLUSIONS: A remnant blood concentration above 38 mg/dL was highly prevalent among Mexicans. Remnants were significantly associated with a higher risk of diabetes, hypertension, obesity, and cardiovascular risk. This association occurred independently of other lipid markers.

RESUMO

The present review of noncaloric sweeteners (NCSs) by the Asociación Mexicana de Gastroenterología was carried out to analyze and answer some of the most frequent questions and concerns about NCS consumption in patients with gastrointestinal disorders, through a thorough review of the medical literature. A group of gastroenterologists and experts on nutrition, toxicology, microbiology, and endocrinology reviewed and analyzed the published literature on the topic. The working group formulated conclusions, based on the scientific evidence published, to give an opinion with respect to NCS ingestion. Current evidence does not confirm the carcinogenic potential of NCSs. However, the studies analyzed showed that saccharin could have a proinflammatory effect and that polyols can cause gastrointestinal symptoms and manifestations, depending on the dose and type of compound. The ingestion of xylitol, erythritol, sucralose, aspartame, acesulfame K, and saccharin could increase the secretion of the gastrointestinal hormones that regulate intestinal motility, and stevia and its derivatives could have a favorable effect on the percentage of liver fat. Caution should be taken in recommending aspartame consumption in patients with chronic liver disease because it reduces the ratio of branched-chain amino acids to aromatic amino acids. In addition, NCS ingestion could modify the composition of the intestinal microbiota, having an effect on gastrointestinal symptoms and manifestations. It is important to continue conducting causality studies on humans to be able to establish recommendations on NSC consumption.

RESUMO

BACKGROUND: Metabolic syndrome (MetS) may represent risk factor for long-term renal function of kidneys from living donors. The aim of this study was to evaluate the impact of MetS on renal function in donors. METHODS: Data regarding the presence or absence of MetS and renal function, as assessed by estimated glomerular filtration rate (eGFR) were obtained from 140 kidney donors before nephrectomy (BN) and at follow-up (AF). Donors were divided into those with (group 1; n =28) versus without MetS (group 2; n = 112). RESULTS: Comparing the groups, we observed a significantly greater reduction in eGFR among the group with MetS BN versus AF 27.5% (19.3-33.0) versus 21.4% (9.6-34.1 P = .02) respectively using a Cox regression model, including age, gender, serum uric acid, body mass index (BMI), and basal eGFR, MetS BN (hazard ratio = 2.2; 95% confidence interval [CI], 1.21-4.01; p = .01) was an independent factor associated with a greater risk of a-eGFR <70 mL/min/1.73 m(2) at follow-up (P < .001). Additionally, age (hazard ratio = 1.03%; 95% CI, 1.01-1.06; P < .001), and female gender (hazard ratio = 1.86; 95% CI, 1.03-3.36; P = .03) were associated with a greater decrease in eGFR. Individuals with MetS BN showed a GFR <70 mL/min/1.73 m(2) at significantly shorter follow-up time (5.6 ± 0.8 years) versus persons without MetS (12.8 ± 1.0 years; P = .001) CONCLUSION: Kidney donors with MetS BN experiment a significantly greater decrease in eGFR at follow-up.

RESUMO

We describe the changes in the prevalence of overweight and obesity in 4606 students that applied to a Mexican University during 1994 to 2008. The mean (± standard deviation [SD]) age was 17.7 ± 1.2 years-old. Progressive and significant increments of bodyweight (female [F] = 2.6, P = 0.03), body mass index (BMI) (F = 4.4, P = 0.001), and waist circumference (F = 30.08, P < 0.0001) in women, and bodyweight (male [M] = 8.9, P < 0.001), BMI (M = 10.4, P < 0.001), and waist circumference (M = 13.01, P < 0.001) in men were observed. A significant increment (P < 0.05) in the prevalence of overweight since 1994 (n = 87, 12.1%) throughout 1997 (n = 102, 14.1%), 1998 (n = 133, 18.4%), 1999 (n = 1993, 26.8%), and 2008 (n = 206, 19.9%) was documented. Similarly, the prevalence of obesity had a significant increment in all students evaluated (P < 0.0001) since 1994 (n = 29, 13.2%) through 1997 (n = 11, 5.0%), 1998 (n = 45, 20.5%), 1999 (n = 53, 24.1%), and 2008 (n = 82, 37.3%). The increment was significant in both women (P = 0.02) and men (P < 0.001). In summary, we report a significant increment in the prevalence of overweight and obesity in Mexican students living in an urban setting over a time period of 14 years.
