RESUMEN

(1) Background: Evidence regarding Non-Alcoholic Fatty Liver Disease (NAFLD) diagnosis is limited in the context of patients with gallstone disease (GD). This study aimed to assess the predictive potential of conventional clinical and biochemical variables as combined models for diagnosing NAFLD in patients with GD. (2) Methods: A cross-sectional study including 239 patients with GD and NAFLD diagnosed by ultrasonography who underwent laparoscopic cholecystectomy and liver biopsy was conducted. Previous clinical indices were also determined. Predictive models for the presence of NAFLD stratified by biological sex were obtained through binary logistic regression and sensitivity analyses were performed. (3) Results: For women, the model included total cholesterol (TC), age and alanine aminotransferase (ALT) and showed an area under receiver operating characteristic curve (AUC) of 0.727 (p < 0.001), sensitivity of 0.831 and a specificity of 0.517. For men, the model included TC, body mass index (BMI) and aspartate aminotransferase (AST), had an AUC of 0.898 (p < 0.001), sensitivity of 0.917 and specificity of 0.818. In both sexes, the diagnostic performance of the designed equations was superior to the previous indices. (4) Conclusions: These models have the potential to offer valuable guidance to healthcare providers in clinical decision-making, enabling them to achieve optimal outcomes for each patient.

RESUMEN

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) is characterized by ectopic fat deposition in the liver. However, a recent classification of this condition, which also integrates the presence of coexisting metabolic disorders, termed Metabolic dysfunction Associated Fatty Liver Disease (MAFLD), has been proposed. NAFLD is increasingly common in early childhood, partly due to the increase in metabolic disease in this age. Thus, studying hepatic steatosis in the metabolic context has become important in this population as well. However, NAFLD, and thus MAFLD, diagnosis in children is challenging by the lack of non-invasive diagnostic tools comparable to the gold standard of hepatic biopsy. Recent studies have reported that the Pediatric Metabolic Index (PMI) could be a marker of insulin resistance and abnormal liver enzymes, but its association with NAFLD, MAFLD, or altered adipokines in these conditions has not been reported. The aim of this study is to evaluate the correlation between PMI with the diagnosis of NAFLD or MAFLD, together with serum levels of leptin and adiponectin, in school-age children. METHODS: A cross sectional study was carried out in two hundred and twenty-three children without medical history of hypothyroidism, genetic, or chronic diseases. Anthropometry, liver ultrasound, and serum levels of lipids, leptin, and adiponectin were evaluated. The children were classified as having NAFLD or non-NAFLD, and a subgroup of MAFLD in the NAFLD group was analyzed. The PMI was calculated by the established formulas for age and gender. RESULTS: PMI correlated positively with the presence and severity of NAFLD (r = 0.62, p<0.001 and r = 0.79, p<0.001 respectively) and with the presence of MAFLD (r = 0.62; p<0.001). Also, this index correlated positively with serum leptin levels (r = 0.66; p<0.001) and negatively with serum adiponectin levels (r= -0.65; p<0.001). PMI showed to be a good predictor for diagnosing NAFLD in school-age children when performing a ROC curve analysis (AUROC=0.986, p< 0.0001). CONCLUSION: PMI could be a useful tool for the early diagnosis of NAFLD or MAFLD in children. However, future studies are necessary to establish validated cut-off points for each population.

RESUMEN

This study evaluated the prevalence of concomitant use of herbal products for weight loss (HPWL) and allopathic medicine. Factors associated with the prevalence, adverse reactions, and the alteration of medication adherence with the concomitant use of HPWL alone and in combination with allopathic medicine, were assessed. The study was descriptive and cross-sectional using a questionnaire conducted among people with overweight or obesity (n=662) from five cities of Central Mexico. Adherence to medications was measured using the Morisky Medication Adherence Scale. The prevalence of adverse reactions induced by the concomitant use of HPWL, and allopathic medicine was 25.3%. The use of HPWL affected medication adherence by 68%. There is a high prevalence (45.2%) of concomitant use of HPWL and allopathic medicine in people with overweight or obesity in Central Mexico. The concomitant use of HPWL and allopathic medicine induces adverse reactions, mainly gastrointestinal, and thus, medication adherence is affected.


Este estudio evaluó la prevalencia del uso concomitante de productos a base de hierbas para bajar de peso (HPWL) y medicina alopática. Se evaluaron los factores asociados con la prevalencia, las reacciones adversas y la alteración de la adherencia a la medicación con el uso concomitante de HPWL solo y en combinación con medicina alopática. El estudio fue descriptivo y transversal mediante un cuestionario realizado entre personas con sobrepeso u obesidad (n = 662) de cinco ciudades del centro de México. La adherencia a los medicamentos se midió mediante la Escala de adherencia a la medicación de Morisky. La prevalencia de reacciones adversas inducidas por el uso concomitante de HPWL y medicina alopática fue del 25,3%. El uso de HPWL afectó la adherencia a la medicación en un 68%. Existe una alta prevalencia (45.2%) de uso concomitante de HPWL y medicina alopática en personas con sobrepeso u obesidad en el centro de México. El uso concomitante de HPWL y medicina alopática induce reacciones adversas, principalmente gastrointestinales, y por tanto, afecta la adherencia a la medicación.

RESUMEN

Nonalcoholic fatty liver disease (NAFLD) is the main liver disease worldwide, and its prevalence in children and adolescents has been increasing in the past years. It has been demonstrated that parental exposure to different conditions, both preconceptionally and during pregnancy, can lead to fetal programming of several metabolic diseases, including NAFLD. In this article, we review some of the maternal and paternal conditions that may be involved in early-life programing of adult NAFLD. First, we describe the maternal nutritional factors that have been suggested to increase the risk of NAFLD in the offspring, such as an obesogenic diet, overweight/obesity, and altered lipogenesis. Second, we review the association of certain vitamin supplementation and the use of some drugs during pregnancy, for instance, glucocorticoids, with a higher risk of NAFLD. Furthermore, we discuss the evidence showing that maternal-fetal pathologies, including gestational diabetes mellitus (GDM), insulin resistance (IR), and intrauterine growth restriction (IUGR), as well as the exposure to environmental contaminants, and the impact of microbiome changes, are important factors in early-life programming of NAFLD. Finally, we review how paternal preconceptional conditions, such as exercise and diet (particularly obesogenic diets), may impact fetal growth and liver function. Altogether, the presented evidence supports the hypothesis that both in utero exposure and parental conditions may influence fetal outcomes, including the development of NAFLD in early life and adulthood. The study of these conditions is crucial to better understand the diverse mechanisms involved in NAFLD, as well as for defining new preventive strategies for this disease.

RESUMEN

OBJECTIVE: This study aims to assess the prevalence of herbal medicine (HM) use and factors influencing HM usage including the identification of the main plants consumed by patients with type 2 diabetes mellitus (T2DM) in central-western Mexico. DESIGN: A total of 1862 patients with diabetes were surveyed in public and private hospitals in four states (Guanajuato, Jalisco, Michoacan, and San Luis Potosi) of the central-western region of Mexico. The chi-square test was used to assess associations between HM use and demographic characteristics, such as glucose levels, presence of complications and comorbidities, as well as the selected therapy to treat T2DM. RESULTS: The prevalence of HM use (59.2%) in patients with T2DM was mainly associated with education level (p = 0.001), time of diagnosis of T2DM (p = 0.004), presence of complications (p < 0.001) and comorbidities (p = 0.018) and the use of insulin (p < 0.001). These patients report a higher consumption of herbal medicine compared to those on glycemic control (p < 0.001). The most frequently used medicinal plants to treat T2DM were nopal (54.9%), moringa (26.7%), and aloe (22.1%). CONCLUSION: The prevalence of HM use to treat T2DM in west-central Mexico is high (59.2%) and its consumption is mostly carried out without the recommendation of a health professional (91.9%). The use of HM increases mainly when the patient uses insulin, during complications of the disease or in patients with an inadequate glycemic control.

RESUMEN

Background Fibroblast growth factor 21 (FGF21) is considered an important regulator of lipid and glucose metabolism. However, the role of FGF21 in macronutrient intake and metabolic disease, particularly in pediatric population, still needs further clarification. This study aimed to evaluate the association of rs11665896 in the FGF21 gene with metabolic status and macronutrient intake in a cohort of Mexican children with obesity. Methods Eighty-four lean children and 113 children with obesity, from 8 to 11 years of age, were recruited. FGF21 rs11665896 was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Somatometric evaluations, nutrient intake, glucose, lipids, insulin and FGF21 serum levels were measured in the obesity group. Results The T allele of rs11665896 in the FGF21 gene was associated with obesity (odds ratio [OR] = 1.99, 95% confidence interval [CI] = 1.14-3.46; p = 0.0151). Subjects with obesity carrying the TT genotype consumed less lipids and more carbohydrates compared to other genotypes. Circulating FGF21 levels correlated negatively with carbohydrate intake (r = -0.232, p = 0.022) and positively with body weight (r = 0.269, p = 0.007), waist (r = 0.242, p = 0.016) and hip girth (r = 0.204, p = 0.042). FGF21 levels were lower in carriers of at least one T allele. Conclusions Genetic variants in FGF21 could influence metabolic status, food preferences and qualitative changes in nutritional behavior in children.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Mexico ranks second in the world for obesity prevalence. In Mexico, obese and overweight subjects commonly seek alternative treatments for weight-loss, including the use of herbal products. AIM OF THE STUDY: The main objective of this study was to evaluate the prevalence of self-medication with herbal products for weight-loss among overweight and obese subjects residing in four states (Guanajuato, San Luis Potosi, State of Mexico, and Mexico City) from central Mexico. In addition, the factors related to self-medication among patients were studied. MATERIALS AND METHODS: A total of 1404 overweight and obese subjects were interviewed. A chi-square test examined associations between socio-demographic and socio-economic information, and self-medication with herbal products for weight-loss. RESULTS: The prevalence of self-medication was 42.9% among the participants who used herbal products for weight-loss. The female gender was the strongest factor (OR: 2.20 (1.75-2.77) associated with self-medication for weight-loss, followed by a low educational level (elementary and middle school) [OR: 1.80 (1.31-2.44)], and a middle-socioeconomic status [OR: 1.75 (1.21-2.52)]. The main herbal products used for weight-loss were based on: i) green tea, Camellia sinensis (12.7% of frequency), ii) aceitilla, Bidens odorata (6.6%), and iii) soybean, Glycine max (5.3%). In addition, 65% of the respondents considered herbal products ineffective for weight-loss after 6 months of use. CONCLUSION: Due to the high incidence of overweight and obesity in Mexico, there is a high prevalence (42.9%) of self-medication using natural products for weight-loss, particularly in women from Central Mexico. This study indicates the important need to educate patients about the harmful effects of consuming these products.

RESUMEN

Self-medication during pregnancy represents a serious threat for mother and child health. The objective of this study was to evaluate the prevalence and the factors associated with self-medication among Mexican women living in the central region of Mexico. This is a descriptive interview-study of 1798 pregnant women or women who were pregnant no more than 3 years ago, when the interview was carried out. Data analysis was carried out with chi-square analysis and odds ratio. The prevalence of self-medication (allopathic drugs, medicinal plants, and other products, including vitamins, food supplements, among others) was 21.9%. The factors associated (p < 0.05) with self-medication were: higher education (college and postgraduate), smoking, and consumption of alcohol. Smoking was the strongest factor (OR: 2.536; 1.46-4.42) associated to self-medication during pregnancy, followed by consumption of alcohol (OR: 2.06; 1.38-3.08), and higher education (OR: 1.607; 1.18-2.19). Medicinal plant consumption was associated with nausea, constipation, migraine, and cold (p < 0.05), whereas he self-medication of allopathy was associated with gastritis and migraine (p < 0.05). Self-medication was influenced mainly by a relative or friend, who recommended the use of herbal medicine/allopathic medication. Two of the most common medicinal plants (arnica and ruda) here informed are reported to induce abortion or toxicity during pregnancy. The findings showed that self-medication (medicinal plants and allopathic medication) is a common practice among pregnant women from central Mexico. Adequate counselling of pregnant women by healthcare professionals about the potential risks of self-medication with herbal medicine and allopathic drugs during pregnancy is strongly warranted.

RESUMEN

BACKGROUND: Women after menopause increase risk for cardiovascular disease and several factors may be related. The purpose was to study biological and psychosocial factors associated with early cardiovascular damage in pre- and postmenopausal women, assessed with carotid intima-media thickness vs flow-mediated dilatation. METHODS: Women 45 to 57 years old were grouped in the pre- (n = 60), early (n = 58) and late post-menopause (n = 59). Anthropometric, metabolic and hormonal data were registered, as well as measures of depression, anxiety, submission, perceived stress, and sleep alterations. Heart Rate Variability was recorded to obtain the information regarding sympathovagal balance. Carotid intima-media thickness and flow-mediated dilatation were assessed by ultrasound. Two-way ANOVA and multiple regression model were used. RESULTS: At late postmenopause, the carotid intima-media was thicker (p < 0.001) and flow-mediated dilatation decreased (p < 0.001). Carotid intima-media thickness was associated positively with age (p < 0.001), submission score (p = 0.029), follicle stimulating hormone levels (p < 0.001), and body mass index (p = 0.009). Flow-mediated dilatation was associated only with age (p < 0.001). Regarding heart rate variability, the time domain pNN50 measurement was higher in premenopausal women (p = 0.001), Low Frequency (LF) was higher in the two groups of postmenopausal (p = 0.001) and High Frequency (HF) higher in the early postmenopausal women (p = 0.042). CONCLUSIONS: Under our conditions carotid intima-media thickness had higher predictive value for early cardiovascular damage at menopause. The finding of the association of the submission score, indicates de influence of stress on vascular damage.

RESUMEN

BACKGROUND/AIMS: The alterations of eating behavior are insufficiently recognized in the clinical attention of adults with obesity. The objective of this study was to examine the characteristics of overeating behavior and its association with depression, perceived stress, acylated ghrelin, nestafin-1, and cortisol. METHODS: This cross-sectional comparative study included 80 participants with obesity and 50 with normal weight. The volunteers completed questionnaires to evaluate symptoms of food addiction (FA), obsessive compulsive, binge eating (BE), depression, and perceived stress. We measured glucose, lipids, acylated ghrelin, nesfatin-1, and insulin in a fasting blood sample as well as urine cortisol. We compared groups with students t test, and analysis of variance, and tested associations by logistic and multiple regression. RESULTS: By multiple regression, the BE total score was positively associated with the FA (p < 0.0001) and depression total score (p < 0.0001). By logistic regression, the positive score of FA was associated with ghrelin (p < 0.02). The perceived stress total score was associated negatively with cortisol (p < 0.0006). CONCLUSION: The BE and FA are strongly associated in agreement with the concept that both conditions have overlapping features. Depressive symptoms are associated with symptoms of disordered eating -behavior. FA positive score was associated with ghrelin. BE total score was associated with nesfatin-1.

RESUMEN

OBJECTIVE: We examined the effect of restriction of foods with high fructose content in obese school children. METHODS: In a clinical study, we selected 54 obese children 6 to 11 years old with high fructose consumption (>70 g/day) in order indicate dietary fructose restriction (<20 g/day) for 6 weeks. Anthropometry, liver ultrasound as well as glucose, insulin, lipids, leptin, IGFBP1, and RBP4 serum levels were collected. RESULTS: The group of children had 80% adherence and reported decreased fructose consumption (110 ± 38.6 to 11.4 ± 12.0 g/day) and also a significant decrease in caloric (2,384 ± 568 to 1,757 ± 387 kcal/day) and carbohydrate consumption (302 ± 80.4 to 203 ± 56.0 g/day). The severity of steatosis improved significantly after fructose restriction (p < 0.000001). However, no changes in BMI, systolic blood pressure, or diastolic blood pressure were found. Only triglyceride levels decreased (1.44 ± 0.43 to 1.31 ± 0.38 mmol/l), High-densitiy lipoprotein cholesterol showed a marginal increase (1.45 ± 0.19 to 1.56 ± 0.44 mmol/l). Insulin resistance and RBP4 did not change. CONCLUSIONS: In school children, the restriction of high fructose foods with a decrease of caloric and carbohydrate intake at 6 weeks did not induce weight loss; however, triglyceride levels and hepatic steatosis decreased. Differences with other studies in regard to weight loss may be explained by adaptive changes on metabolic expenditure.

RESUMEN

BACKGROUND: Obesity is significant problem involving eating behavior and peripheral metabolic conditions. The effect of carbohydrate and fat restriction on appetite regulation, fibroblast growth factor 21 (FGF21) and leptin in children has not been defined. Our objective was to compare the effect of both diets. METHODS: One hundred and twenty children with body mass index (BMI) higher than the equivalent of 30 kg/m(2) for an adult, as corrected for gender and age were randomly assigned to (n = 60) a low-carbohydrate (L-CHO) diet or (n = 60) a low-fat (L-F) diet for 2 months. Fifty-three (88.3 %) subjects on the low-carbohydrate-diet and 45 (75 %) on the low-fat diet completed the study. Anthropometric measures, leptin and FGF21 levels were measured before and after the intervention. Comparison of the data for both of the diet groups was carried out using the t-test for independent variables. Intragroup comparisons before and after of each of the dietary treatments were performed using ANOVA for repeated measures. Factors associated with FGF21, leptin levels and satiety, were analyzed by multiple regression. RESULTS: After both of the diets, weight, leptin, food responsiveness, and enjoyment of food significantly decreased and high density lipoprotein cholesterol (HDL) increased, but FGF21 decreased. Before and after both of the interventions FGF21 was associated with triglycerides. Before the diet, satiety was associated with lower screen time (p < 0.04) and insulin levels (p < 0.05). CONCLUSIONS: Both dietary restrictions improved the metabolic and hormonal parameters of obese children. FGF21 is an indicator of a beneficial metabolic response in younger children. After 2 months an adaptation of the eating behavior to food restriction was observed.

RESUMEN

BACKGROUND AND AIMS: The risk for cardiovascular diseases (CVD) increases after menopause. Heart rate variability (HRV), a measure of autonomic control, is a strong predictor of CVD. We undertook this study to test the association of ultrasound indices of early carotid atherosclerosis with HRV, symptoms, hormonal conditions, metabolic state, indicators of stress, and psychosocial factors in women at peri- and postmenopause, registering ambulatory R-R interval monitoring. METHODS: In a cross-sectional design we studied 100 women at peri- and early postmenopause collecting anthropometry, symptoms, stress-related measurements, metabolic variables, cortisol, FSH and estradiol. We evaluated carotid ultrasonographic indices, and HRV was recorded for 4 h calculating time (SDNN, pNN50, rMSSD) and frequency domains (LF, HF, LF/HF) in women according to menopausal stage, estradiol levels, body mass index and waist circumference. RESULTS: Carotid indices were similar in peri- and postmenopausal women. For HRV measurements, SDNN was increased at postmenopause. Women with estradiol levels <109.2 pmol/L had increased intima-media thickness (IMT), resistive index, and systolic diameter. Using multivariate analysis, we found the associations of IMT positively with non-HDL-cholesterol, resistive index positively with LF-HRV, but negatively with effort/reward imbalance, carotid ß stiffness index inversely with estradiol, and arterial distensibility positively with HF-HRV and creatinine concentrations, but negatively with non-HDL-cholesterol. CONCLUSIONS: Carotid thickness was related mainly with lipid alterations. Indices of early carotid damage were related with various components of HRV as a manifestation of autonomic imbalance, indicating CVD risk. Other factors involved were time since last menses and psychological stress. Low creatinine was associated with diminished carotid distensibility. This suggests that estrogen, lifestyle, behavior and autonomic regulation participate in vascular damage.

RESUMEN

BACKGROUND: Insulin resistance may be assessed as whole body or hepatic. OBJECTIVE: To study factors associated with both types of insulin resistance. METHODS: Cross-sectional study of 182 obese children. Somatometric measurements were registered, and the following three adiposity indexes were compared: BMI, waist-to-height ratio and visceral adiposity. Whole-body insulin resistance was evaluated using HOMA-IR, with 2.5 as the cut-off point. Hepatic insulin resistance was considered for IGFBP-1 level quartiles 1 to 3 (<6.67 ng/ml). We determined metabolite and hormone levels and performed a liver ultrasound. RESULTS: The majority, 73.1%, of obese children had whole-body insulin resistance and hepatic insulin resistance, while 7% did not have either type. HOMA-IR was negatively associated with IGFBP-1 and positively associated with BMI, triglycerides, leptin and mother's BMI. Girls had increased HOMA-IR. IGFBP-1 was negatively associated with waist-to-height ratio, age, leptin, HOMA-IR and IGF-I. We did not find HOMA-IR or IGFBP-1 associated with fatty liver. CONCLUSION: In school-aged children, BMI is the best metric to predict whole-body insulin resistance, and waist-to-height ratio is the best predictor of hepatic insulin resistance, indicating that central obesity is important for hepatic insulin resistance. The reciprocal negative association of IGFBP-1 and HOMA-IR may represent a strong interaction of the physiological processes of both whole-body and hepatic insulin resistance.
