Evening types as determined by subjective and objective measures are more emotional eaters.

OBJECTIVE: This study aimed to determine the association between being an evening type (ET; defined subjectively by the Morning-Evening Questionnaire or objectively by the dim-light melatonin onset [DLMO] timing) and reporting emotional eating (EE) behaviors. METHODS: Cross-sectional analyses were conducted in 3964 participants (four international cohorts: ONTIME and ONTIME-MT [both Spain], SHIFT [the US], and DICACEM [Mexico]), in which chronotype (Morning-Evening Questionnaire), EE behaviors (Emotional Eating Questionnaire), and dietary habits (dietary records or food-frequency questionnaire) were assessed. Among 162 participants (ONTIME-MT subsample), additional measures of DLMO (physiological gold standard of circadian phase) were available. RESULTS: In three populations, ETs presented with a higher EE score than morning types (p < 0.02); and they made up a higher proportion of emotional eaters (p < 0.01). ETs presented with higher scores on disinhibition/overeating as well as food craving factors and experienced these behaviors more frequently than morning types (p < 0.05). Furthermore, a meta-analysis showed that being an ET was associated with a higher EE score by 1.52 points of a total of 30 points (95% CI: 0.89-2.14). The timing of DLMO in the early, intermediate, and late objective chronotypes occurred at 21:02 h, 22:12 h, and 23:37 h, with late types showing a higher EE score (p = 0.043). CONCLUSIONS: Eveningness associated with EE in populations with different cultural, environmental, and genetic backgrounds. Individuals with late DLMO also showed more EE.

Food insecurity was negatively associated with adherence to the "fruits, vegetables, and foods rich in animal protein" dietary pattern among university students' households: the 2018 Mexican National Household Survey.

BACKGROUND: University students are often affected by food insecurity (FI) and this situation has been associated with low consumption of fruit/vegetables and high intake of added sugars and sweet drinks. However, there needs to be more evidence on the association between FI and dietary patterns (DPs), assessing the overall diet and allowing analysis of commonly consumed food combinations. We aimed to analyze the association between FI and DPs in university students' households. METHODS: We used data from 7659 university student households from the 2018 Mexican National Household Income and Expenditure Survey (ENIGH, for its acronym in Spanish). We obtained FI levels (mild, moderate, and severe) using the validated Mexican Food Security Scale (EMSA, Spanish acronym). Two DPs were identified by principal component analysis based on the weekly frequency of consumption of 12 food groups. Multivariate logistic regression adjusted by university student and household's characteristics was applied. RESULTS: Compared to food security, households with mild-FI (OR:0.34; 95%CI:0.30, 0.40), moderate-FI (OR:0.20; 95%CI:0.16, 0.24) or severe-FI (OR:0.14; 95%CI:0.11, 0.19) were less likely to adhere to the dietary pattern "Fruits, vegetables and foods rich in animal protein" (fruits, vegetables, meat, fish or seafood, dairy products, and starchy vegetables). In addition, people with severe-FI (OR:0.51; 95% CI:0.34, 0.76) were also less likely to adhere to the dietary pattern "Traditional-Westernized" (pulses, oils or fats, sugar, sweets, industrialized drinks, foods made from corn/maize, wheat, rice, oats or bran, coffee, tea and eggs). CONCLUSIONS: In these households FI impairs the ability to consume a healthy dietary pattern (fruits/vegetables and foods rich in animal protein). In addition, the intake of foods typical of the Mexican food culture reflecting the local Western dietary pattern is compromised in households with severe-FI.

Indoor and Outdoor Cultures of Gracilaria chilensis: Determination of Biomass Growth and Molecular Markers for Biomass Quality Evaluation.

Taking into consideration climate change scenarios, marine contamination, and a constantly expanding world population, seaweed aquaculture has become an important option for the large-scale production of high-quality biomass. Due to existing biological knowledge of Gracilaria chilensis, several cultivation strategies have been established for obtaining diverse biomolecules (lipids, fatty acids, pigments, among others) with nutraceutical properties. In this research, indoor and outdoor cultivation methodologies were applied to generate high biomass of G. chilensis with positive quality for productive purposes, where the quality was determined according to the concentrations of lipoperoxides and phenolic compounds and the total antioxidant capacity (TAC). The results showed that G. chilensis cultures, which were fertilized for three weeks with Basfoliar® Aktiv (BF) at concentrations of 0.05-1% v/v, obtained high biomass (1-1.3 kg m-2) and DGR (0.35-4.66% d-1), low lipoperoxides (0.5-2.8 µmol g-1 DT), and high phenolic compounds (0.4-0.92 µ eq. GA g-1 FT) and TAC (5-7.5 nmol eq. TROLOX g-1 FT) as compared with other culture media. Lower stress was determined under indoor cultures, due to the operative control of diverse physicochemical stressor parameters (T°, light intensity, photoperiod, among others). Therefore, the cultures developed allow scaling the biomass in productive terms and are suitable for obtaining compounds of interest.

A 24-month clinical evaluation of composite resins with different viscosity and chemical compositions: a randomized clinical trial.

OBJECTIVES: To evaluate the clinical performance of two methacrylate-based flowable composites and an ormocer-based flowable composite in noncarious cervical lesions (NCCLs) in adult participants. METHOD AND MATERIALS: In total, 183 restorations were performed on NCCLs. All cavities were restored using a universal adhesive system (Futurabond U, Voco) with selective enamel etching and with one of the three evaluated flowable composites (n = 61): low-viscosity methacrylate-based composite (GrandioSO Flow, LV), high-viscosity methacrylate-based composite (GrandioSO Heavy Flow, HV), and an ormocer-based flowable composite (Admira Fusion Flow, ORM). All restorations were evaluated using FDI and USPHS criteria after 24 months. Kruskall-Wallis analysis of variance rank (α = .05) was used for statistical analysis. RESULTS: After 24 months of clinical evaluation, 16 restorations were lost (LV = 3, HV = 10, ORM = 3) and the retention rates (95% confidence interval) were 95.0% for LV, 82.2% for HV, and 95.0% for ORM, with statistical differences observed between HV and LV as well as HV and ORM (P < .05). When secondary parameters were evaluated, no significant differences between groups were observed (P > .05). Thirty-three restorations (LV = 8, HV = 13, ORM = 12) showed minor marginal staining, 71 restorations (LV = 26, HV = 20, ORM = 25) presented small marginal adaptation defects, and one restoration for HV presented recurrence of caries. CONCLUSION: The universal adhesive associated with the ormocer-based and methacrylate-based flowable composite showed promising clinical performance after 24 months. However, the heavy-flow restorations showed significantly more failures. (Quintessence Int 2023;54:186-199; doi: 10.3290/j.qi.b3631841).

Automatic identification of intestinal parasites in reptiles using microscopic stool images and convolutional neural networks.

Captive environments trigger the propagation and multiplication of parasites among different reptile species, thus weakening their immune response and causing infections and diseases. Technological advances of convolutional neural networks have opened a new field for detecting and classifying diseases which have shown great potential to overcome the shortcomings of manual detection performed by experts. Therefore, we propose an approach to identify six captive reptiles parasitic agents (Ophionyssus natricis, Blastocystis sp, Oxiurdo egg, Rhytidoides similis, Strongyloides, Taenia) or the absence of such parasites from a microscope stool images dataset. Towards this end, we first use an image segmentation stage to detect the parasite within the image, which combines the Contrast Limited Adaptive Histogram Equalization (CLAHE) technique, the OTSU binarization method, and morphological operations. Then, we carry out a classification stage through MobileNet CNN under a transfer learning scheme. This method was validated on a stool image dataset containing 3616 images data samples and 26 videos from the six parasites mentioned above. The results obtained indicate that our transfer learning-based approach can learn a helpful representation from the dataset. We obtained an average accuracy of 94.26% across the seven classes (i.e., six parasitic agents and the absence of parasites), which statistically outperformed, at a 95% confidence level, a custom CNN trained from scratch.

Methodological Aspects in Randomized Clinical Trials of Nutritional Interventions.

Nutrition is an essential component when promoting human health. Without a doubt, improving the quality of one's diet can improve one's quality of life as a whole and help postpone the onset or control of many chronic diseases. The volume of publications in this field has increased in recent years, in line with increased awareness of the importance of nutrition in health; however, the quality of the evidence on which most nutritional guidelines are based remains low, due to errors in conducting nutritional interventions or because the information is primarily derived from observational studies. To enhance the evidence supporting clinical guidelines in nutrition, the quality of randomized clinical trials (RCT) based on nutritional interventions must be improved; nevertheless, due to their heterogeneous nature and a lack of specific guidelines for designing, performing, documenting, and reporting on this type of intervention, conducting a nutritional intervention is a real challenge. Following a review of the literature on the methodological and ethical standards, as well as four extensions of the CONSORT (Consolidated Standards of Reporting Trials) guidelines that should be considered when implementing a nutritional intervention, seven essential aspects were identified. The current narrative review includes definitions, examples, diagrams, and algorithms regarding aspects of the appropriate study design, the intervention of the control group, the randomization and blinding processes, the study population selection, as well as a description of the type of intervention and the personnel involved in carrying out the study in order to make the implementation of a nutritional intervention easier.

Emotional Eating and Dietary Patterns: Reflecting Food Choices in People with and without Abdominal Obesity.

Emotional eating (EE) is food consumption in response to feelings rather than hunger. EE is related to unhealthy food intake and abdominal obesity (AO). However, little evidence exists about the association between EE and dietary patterns (DPs) and EE−AO interaction related to DPs. DPs allow describing food combinations that people usually eat. We analyzed the association of EE with DPs in adults (≥18 years) with AO (WC ≥ 80/90 cm in women/men, respectively; n = 494; 66.8% women;) or without AO (n = 269; 74.2% women) in a cross-sectional study. Principal component analysis allowed identifying four DPs from 40 food groups (validated with a semiquantitative food frequency questionnaire). Among the subjects presenting AO, being "emotional/very-emotional eater" (emotional eating questionnaire) was negatively associated with the "Healthy" DP (fruits, vegetables, olive oil, oilseeds, legumes, fish, seafood) (OR:0.53; 95% CI: 0.33, 0.88, p = 0.013) and positively with the "Snacks and fast food" DP (sweet bread, breakfast cereal, corn, potato, desserts, sweets, sugar, fast food) (OR:1.88; 95% CI: 1.17, 3.03, p = 0.010). Emotional eaters with AO have significantly lower fiber intake, folic acid, magnesium, potassium, vitamin B1, and vitamin C, while they had a higher intake of sodium, lipids, mono and polyunsaturated fatty acids, and saturated fats. In non-AO participants, EE was not associated with any DP (p > 0.05). In conclusion, EE is associated with unhealthy DPs in subjects with AO.

The Effect of Dietary Interventions on Hypertriglyceridemia: From Public Health to Molecular Nutrition Evidence.

Approximately 25-50% of the population worldwide exhibits serum triglycerides (TG) (≥150 mg/dL) which are associated with an increased level of highly atherogenic remnant-like particles, non-alcoholic fatty liver disease, and pancreatitis risk. High serum TG levels could be related to cardiovascular disease, which is the most prevalent cause of mortality in Western countries. The etiology of hypertriglyceridemia (HTG) is multifactorial and can be classified as primary and secondary causes. Among the primary causes are genetic disorders. On the other hand, secondary causes of HTG comprise lifestyle factors, medical conditions, and drugs. Among lifestyle changes, adequate diets and nutrition are the initial steps to treat and prevent serum lipid alterations. Dietary intervention for HTG is recommended in order to modify the amount of macronutrients. Macronutrient distribution changes such as fat or protein, low-carbohydrate diets, and caloric restriction seem to be effective strategies in reducing TG levels. Particularly, the Mediterranean diet is the dietary pattern with the most consistent evidence for efficacy in HTG while the use of omega-3 supplements consumption is the dietary component with the highest number of randomized clinical trials (RCT) carried out with effective results on reducing TG. The aim of this review was to provide a better comprehension between human nutrition and lipid metabolism.

Desiccation Stress Tolerance in Porphyra and Pyropia Species: A Latitudinal Analysis along the Chilean Coast.

One of the most important factors regulating the distribution and abundance of seaweeds is desiccation, triggered mainly by tidal changes and climatic variation. Porphyra and Pyropia species have evolved multiple strategies to tolerate desiccation stress; however, how these tolerance strategies differ in these species inhabiting different latitudes is still unknown. In this context, we analyzed, in situ, the physiological responses of these species (collected from 18° S to 41° S along the Chilean coast) to desiccation stress using biochemical and molecular analyses. The hyper-arid terrestrial climate of northern Chile, with high evaporation and lack of constant rain determines a very steep increase in desiccation stress in the upper intertidal during low tide for these species. Accordingly, the results showed that, in comparison with the southernmost populations, the Porphyra/Pyropia species from the north zone of Chile (18°-30° S) exhibited higher contents of lipoperoxide and carbonyls (1.6-1.9 fold) together with higher enzymatic activities, including ascorbate peroxidase, catalase, peroxiredoxin, and thioredoxin (2-3-fold). In addition, a substantial expression of cat, prx, and trx transcripts during desiccation was demonstrated, mainly in the northernmost populations. These results provide evidence of (i) significant activation of antioxidant enzymes and transcripts (principally cat and prx); (ii) participation of phenolic antioxidant compounds as a highly plastic physiological strategy to cope with desiccation; and (iii) the activation of the tolerance responses was affected by species latitudinal distribution. Thus, for the first time, this study integrated the biochemical and genetic responses of diverse Porphyra/Pyropia species to better understand their physiological dynamics of tolerance over a wide latitudinal range.

A universal adhesive containing copper nanoparticles improves the stability of hybrid layer in a cariogenic oral environment: An in situ study.

PURPOSE: To evaluate how incorporating copper nanoparticles (CuNp) into a universal adhesive affects the antimicrobial activity (AMA), bond strength (µTBS), nanoleakage (NL), elastic modulus (EM) and nanohardness (NH) of resin-dentin interfaces, at 24 h (24 h) and after in situ cariogenic challenge (CC). METHODS: CuNp (0% [control] and 0.1 wt%) was added to an adhesive. After enamel removal, the adhesives were applied to dentine surfaces. Each restored tooth was sectioned longitudinally to obtain two hemi-teeth; one of them was evaluated after 24 h, and the other was included in one of the intra-oral palatal devices placed in the mouths of 10 volunteers for 14 days in CC. After that, each hemi-tooth was removed, and any oral biofilm that formed was collected. The AMA was evaluated against Streptococcus mutans. For the 24 h and CC groups, each hemi-tooth was sectioned in the "x" direction to obtain one slice for each EM/NH evaluation. The remains of each hemi-tooth were sectioned in the "x" and "y" directions to obtain resin-dentin beams for µTBS and NL evaluation (24 h and CC). ANOVA and Tukey's test were applied (α = 0.05). RESULTS: The presence of CuNp significantly improved AMA as well as all of the evaluated properties (24 h; p < 0.05). Although the adhesive properties (µTBS/NL) for all groups decreased after CC (p < 0.05), the adhesive containing CuNp showed higher µTBS and lower NL as compared to the copper-free adhesive (p < 0.05). The incorporation of CuNp maintained NH/EM values after CC (p < 0.05). CONCLUSIONS: Adding 0.1% CuNp to an adhesive may provide antimicrobial activity and increase its bonding and mechanical properties, even under a cariogenic challenge. SIGNIFICANCE: This is the first in situ study proving that incorporating CuNp into an adhesive is an achievable alternative to provide antimicrobial properties and improve the integrity of the hybrid layer under in situ cariogenic challenge.

Prevalence and Risk Factors of Food Insecurity among Mexican University Students' Households.

Household food insecurity (FI) remains a major public health challenge worldwide. Data about perceived FI and its risk factors in Mexican university students are lacking. We aimed to assess FI's prevalence and factors affecting it among university students' households in Mexico. This cross-sectional analysis involved 7671 university students' households using the 2018 Mexican National of Household Income and Expenditure Survey data. Variables analyzed included sociodemographic characteristics, and the 12-item validated Mexican Scale for Food Security (EMSA). Multivariable logistic regression modelling was performed to identify FI risk factors. The overall household FI prevalence was 30.8%. According to FI severity, prevalence rates were 16.3% for mild-FI, 8.8% for moderate-FI, and 5.7% for severe-FI. Low socioeconomic status (OR = 2.72; 95%CI: 2.09-3.54), low education level of household's head (OR = 2.36; 95%CI: 1.90-2.94), self-ascription to an indigenous group (OR = 1.59; 95%CI: 1.41-1.79), attending public university (OR = 1.27; 95%CI: 1.13-1.43), female-headed household (OR = 1.26; 95%CI: 1.13-1.40), having worked recently (OR = 1.19; 95%CI: 1.07-1.33), and being in second year of studies (OR = 1.17; 95%CI: 1.03-1.33), were significantly related to FI. Our results confirm that FI is highly prevalent among Mexican university students' households and that sociodemographic factors are essential in addressing this concern. Findings highlight the need for preventive programs and policies to alleviate FI.

Synergistic, antagonistic, and additive effects of heavy metals (copper and cadmium) and polycyclic aromatic hydrocarbons (PAHs) under binary and tertiary combinations in key habitat-forming kelp species of Chile.

Heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs) are persistent toxicants in coastal environments. Notably, in comparison to individual metal toxicity, knowledge about the effects of HMs and PAHs mixtures on kelps remains scarce. Accordingly, we performed in vitro experiments to determine the individual and combined effects of Cu, Cd, and PAHs on spore release, settlement, and germination on Macrocystis pyrifera and Lessonia spicata, two key-habitat forming kelp species of the coast of the Valparaíso Region in Chile. This region concentrates highly polluting industries, mainly due to unrestrained mining and fossil-fuel energy production. Single Cu, Cd, and PAHs treatments included concentrations in the ranges 5-200, 0.125-2000, and 0.05-100 µg/L, respectively, and a toxic-free treatment. Cu, Cd, and PAHs concentrations causing 20-50% (IC20, IC50) arrested spore release, settlement, and germination were determined, and the results shown in both species that single Cu, Cd, and PAHs IC20 values were generally lower on spore release than on spore settlement and germination, probably due to the absence of a cell wall in spores compared to later stages. Binary equitoxic IC20s mixture treatments changed from an antagonistic response to another with a greater inhibitory effect on spore release, from hour 1 to 7, whereas in IC50 treatments, the response was always antagonistic. The tertiary IC20 mixture of Cu+Cd+PAHs produced generally an antagonistic effect. Remarkably, all IC20 equitoxic mixture treatments showed a synergistic response on spore settlement in both kelps, suggesting that these toxicants are extremely harmful to kelp population persistence near highly polluted sites.

Factors Associated with Hopelessness and the Role of Social Networks Among Chinese Older Adults.

OBJECTIVE: The levels of hopelessness affect older adults' physical and mental health. However, there has been a lack of research on the hopelessness among Chinese older adults. The aims of this study were to explore factors associated with hopelessness and the moderating role of social networks among Chinese older adults. METHOD: We conducted a cross-sectional study among older adults (n = 837) from nine communities in Xi'an and Beijing in China, and collected the participants' levels of hopelessness, demographic information (age and gender), socioeconomic status (marital status, education, monthly income, living status, and alimony), life satisfaction, health information (self-rated health and sleep quality), and quality of social networks. RESULTS: Of the participants, 61.9% reported different levels of hopelessness symptoms; 71.2% reported poor sleep quality, and 21.1% reported low levels of social networks. A hierarchical multiple regression analysis showed that marital status, monthly income, alimony, life satisfaction, and sleep quality were significantly associated with hopelessness. A PROCESS analysis demonstrated that social networks played a moderating role in the relationship between sleep quality and hopelessness. CONCLUSION: Chinese older adults who had no spouse, had lower incomes, and were dissatisfied with life were more likely to have higher levels of hopelessness. Furthermore, older adults who did not receive financial support from their children reported higher levels of hopelessness. In addition, the worse the sleep quality the higher levels of hopelessness in older adults. However, high levels of social networks could weaken the negative effect of sleep quality on hopelessness.

Metabolic Syndrome Among Young Health Professionals in the Multicenter Latin America Metabolic Syndrome Study.

Background: Metabolic syndrome (MS) and its components increase the risk of a number of chronic diseases. Evidence regarding its prevalence among health professionals, particularly in Latin America, is limited. The purpose of this study was to assess the overall prevalence of MS and its components among health professionals and students from five Latin American countries. Methods: A cross-sectional multicenter study entitled LATIN America METabolic Syndrome (LATINMETS) was conducted on five groups of apparently healthy volunteer subjects. Sociodemographic factors, lifestyle variables (smoking and physical activity), anthropometric measurements (weight, height, and waist circumference), standard biochemical analyses [triglycerides, glucose, and high-density lipoprotein cholesterol (HDL-C)], and blood pressure measurements were assessed. MS was diagnosed based on internationally harmonized criteria. Associations between MS components and sociodemographic, lifestyle, and anthropometric variables were analyzed using multivariate logistic regression. Results: A total of 1,032 volunteers (n = 316-Mexico, n = 285-Colombia, n = 223-Brazil, n = 132-Paraguay, and n = 76-Argentina) were recruited. The majority of them were women (71.9%), students (55.4%), and younger than 28 years (67.2%). The overall prevalence of age-standardized MS was 15.5% (23.1% men and 12.2% women). The majority (59.3%) presented at least one MS component, mainly abdominal obesity (29.7%) and low HDL-C levels (27.5%). After adjusting for age and sex, MS and its components were positively associated with being overweight or obese. Conclusions: MS prevalence in this study was similar to that generally found among young populations in Latin-American countries. More than half of the sample had at least one MS component, suggesting that preventive measures and treatments aimed at achieving low-risk health status are essential in this population.

Luxación erecta expuesta de hombro en un niño: reporte de un caso / Erect shoulder dislocation in a child: case report / Erecto luxação do ombro em uma criança: relato de caso

La luxación erecta expuesta de hombro es una asociación lesional de muy baja frecuencia en la edad pediátrica. Son más frecuentes las lesiones fisarias y epifisarias que las luxaciones y lesiones ligamentarias. Esto es debido a la presencia de un tejido óseo con gran poder de deformidad elástica y un periostio grueso. Presentamos un caso clínico de un paciente de 11 años de edad que sufrió una luxación erecta expuesta de hombro derecho, producto de una caída de 1 metro y medio de altura. El tratamiento consistió en una limpieza quirúrgica de urgencia, reducción gleno humeral y antibioticoterapia empírica, penicinila 400.000 UI/kg/día fraccionado cada 6 hs y gentamicina 3mg/Kg/día fraccionada cada 8 h por 10 días, inmovilización por 3 semanas con cabestrillo seguido de rehabilitación, y un follow up de 2 años al final del cual el paciente no presento secuelas funcionales en la articulación glenohumeral derecha.

The exposed erect dislocation of the shoulder is a very low frequency lesion association in the pediatric age. The physical and epiphyseal lesions are more frequent than the dislocations and ligament injuries. This is due to the presence of a bone tissue with great elastic deformity power and a thick periosteum. We present a clinical case of an 11-year-old patient who suffered an exposed erect dislocation of the right shoulder, due to a fall of 1 meter and a half high. The treatment consisted of emergency surgical cleaning, humeral gleno reduction and empirical antibiotic therapy, penicinila 400,000 IU/kg/day divided every 6 hours and gentamicin 3mg/Kg/day divided every 8 hours for 10 days, immobilization for 3 weeks with a sling followed by rehabilitation, and a follow-up of 2 years at the end of which the patient did not present functional sequelae in the right glenohumeral joint.

Unhealthy dietary patterns among healthcare professionals and students in Mexico.

BACKGROUND: While dietary patterns (DPs) enable the combination of foods that make up a person's habitual diet to be known, little is known about the DPs of health sector professionals. The objective of this study was to describe the DPs of healthcare students and professionals and assess their association with sociodemographic, lifestyle, anthropometric and biochemical characteristics. METHODS: Cross-sectional design. A sample (n = 319) of healthcare students and professionals in apparent good health who studied or worked at the University of Guadalajara (Mexico) was selected. A semiquantitative food intake frequency questionnaire validated on a Mexican population was administered. Questions covering sociodemographic factors, smoking habits and physical activity were asked. Weight, height, waist circumference, blood pressure, triglycerides, glucose, HDL-cholesterol, LDL-cholesterol and total cholesterol were also measured. DPs were generated from a principal components analysis of 25 food groups, and associations were analyzed using logistic regression adjusted for age and sex. RESULTS: The majority of participants were younger than 29 years (84%), women (71.2%) and students (59.6%). Three DPs were identified: "Traditional Westernized", "Healthy" and "Animal protein and alcoholic beverages". After adjustment, the "Traditional Westernized" DP was positively associated with being younger than 22 years (OR: 2.15; 95%CI: 1.1-4.1); the "Healthy" DP was positively associated with having a daily energy expenditure from physical activity greater than 605 kcal (OR: 4.19; 95%CI: 2.3-7.5), and it was negatively associated with being younger than 22 years (OR: 0.48; 95%CI: 0.2-0.9); and the "Animal protein and alcoholic beverages" DP was positively associated with being male (OR: 3.07; 95%CI: 1.8-5.1) and a smoker (OR: 2.77; 95%CI: 1.2-6.3). No association was found between DPs and anthropometric and biochemical characteristics. CONCLUSIONS: Among the participants evaluated, healthy DP was associated with being physically active while unhealthy DPs were associated with being younger than 22 years, male and a smoker. These data suggest that being knowledgeable about health does not ensure that individuals will engage in healthy behaviors. As is the case among the general population, training and individual efforts aimed at achieving healthy behaviors must be reinforced by initiatives undertaken by social groups, social institutions, the community at large as well as political and business leaders.

Metabolic syndrome components in young health professionals; LATIN America METabolic Syndrome (LATINMETS) Mexico study.

INTRODUCTION: metabolic syndrome (MS) components are independent risk factors for the development of cardiovascular disease and type 2 diabetes, major causes of mortality in the world. OBJECTIVE: to evaluate the frequency of MS components and its association with sociodemographic variables and physical activity among young health professionals at the University of Guadalajara. METHODS: a cross-sectional study entitled LATIN America METabolic Syndrome Mexico (LATINMETS-Mex) was conducted. Weight, height, waist circumference, blood pressure, triglycerides, glucose and HDL cholesterol were measured. Socio-demographic and physical activity data were surveyed. MS components were diagnosed based on the revised criteria of Alberti et al. (2009). Associations were assessed using logistic regression adjusted for age and sex. RESULTS: a total of 316 volunteer subjects were analyzed (70.9% women, 83.8% ≤ 29 years). The frequency of MS was 7.0% and 55.5% of subjects presented one or more MS components (27.2% abdominal obesity, 26.6% low HDL cholesterol). After adjustment, abdominal obesity, high blood pressure and hypertriglyceridemia were positively associated with BMI ≥ 25 kg/m2. High blood pressure and hypertriglyceridemia were negatively associated with being female while low HDL cholesterol was positively associated with this gender after adjustment. Abdominal obesity was the only component negatively associated with physical activity (300 to 600 minutes per week) after adjusting for age and sex. No association between MS and sociodemographic variables or physical activity was found. CONCLUSIONS: half of the participants presented one or more metabolic syndrome components. Actions are required to reduce cardiometabolic risk in the study population considering the sociodemographic and lifestyle variables associated.

Results: a total of 316 volunteer subjects were analyzed (70.9% women, 83.8% ≤ 29 years). The frequency of MS was 7.0% and 55.5% of subjects presented one or more MS components (27.2% abdominal obesity, 26.6% low HDL cholesterol). After adjustment, abdominal obesity, high blood pressure and hypertriglyceridemia were positively associated with BMI ≥ 25 kg/m2. High blood pressure and hypertriglyceridemia were negatively associated with being female while low HDL cholesterol was positively associated with this gender after adjustment. Abdominal obesity was the only component negatively associated with physical activity (300 to 600 minutes per week) after adjusting for age and sex. No association between MS and sociodemographic variables or physical activity was found. Conclusions: half of the participants presented one or more metabolic syndrome components. Actions are required to reduce cardiometabolic risk in the study population considering the sociodemographic and lifestyle variables associated

Introducción: los componentes del síndrome metabólico (SM) son factores de riesgo independientes para desarrollar enfermedades cardiovasculares y metabólicas, principales causas de mortalidad en el mundo. Objetivo: evaluar la frecuencia de componentes del SM y su asociación con variables sociodemográficas y actividad física en profesionales de la salud jóvenes de la Universidad de Guadalajara. Métodos: diseño transversal derivado del estudio multicéntrico LATIN America METabolic Syndrome (LATINMETS). Se midieron peso, talla, cintura, presión arterial y concentración sanguínea de triglicéridos, glucosa y colesterol HDL. Se preguntaron datos sociodemográficos y actividad física. Los componentes del SM se diagnosticaron con los criterios de Alberti y cols. (2009). Las asociaciones se evaluaron con regresión logística ajustada por edad y sexo. Resultados: se analizaron 316 voluntarios (70,9% mujeres, 83,8% ≤ 29 años). La frecuencia de SM fue del 7,0% y el 55,5% presentó uno o más componentes (27,2% obesidad abdominal, 26,6% hipocolesterolemia HDL). Después del ajuste, la obesidad abdominal, la presión arterial elevada y la hipertrigliceridemia se asociaron positivamente con un IMC ≥ 25 kg/m2. Ser mujer se asoció negativamente con presión arterial elevada e hipertrigliceridemia y se asoció positivamente con hipocolesterolemia HDL después del ajuste. La obesidad abdominal se asoció negativamente con actividad física (300 a 600 minutos por semana) después de ajustar por edad y sexo. El SM no se asoció con variables sociodemográficas ni de actividad física. Conclusiones: la mitad de los participantes presentaron uno o más componentes del SM. Se requieren acciones para reducir el riesgo cardiometabólico en la población estudiada considerando las variables sociodemográficas y de estilo de vida asociadas

Are cannabinoids effective for HIV wasting syndrome? / ¿Es efectivo el uso de cannabinoides en el síndrome de emaciación (wasting) en VIH/SIDA?

INTRODUCTION: Wasting syndrome is a common problem in HIV. It leads to substantive morbidity and mortality. The use of cannabinoids has been suggested as a treatment for weight, but it is not clear whether they are really safe and effective. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified eight systematic reviews including ten studies overall, of which six were randomized trials. We concluded it is not clear whether cannabinoids increase appetite or weight in HIV wasting syndrome because the certainty of the evidence is very low, and they probably lead to frequent adverse effects.

INTRODUCCIÓN: El síndrome de emaciación (wasting) en VIH/SIDA aún permanece como un problema común, constituyéndose como un factor de mortalidad en esta población. Se ha postulado el uso de cannabinoides como tratamiento de la baja de peso secundaria a la infección por VIH, lo que aún es controvertido. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios y preparamos tablas de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos ocho revisiones sistemáticas que en conjunto incluyen 10 estudios primarios, de los cuales, seis son ensayos aleatorizados. Concluimos que no está claro si los cannabinoides aumentan el apetito o incrementan el peso en el síndrome de wasting en pacientes con VIH, y probablemente los efectos adversos son frecuentes.
