Metabolic syndrome (MetS) is a cluster of metabolic disorders that increases the risk of developing chronic diseases. Cardiometabolic risk factors include high waist circumference (WC), insulin resistance, hypertension, dysglycaemia, dyslipidaemia, and altered inflammatory markers. The aim of this study was to investigate the associations between intakes of polyphenols (total polyphenols and their main classes) and the prevalence of MetS and cardiometabolic risk factors. This study is an observational sub-cohort study of 676 Danish participants of the MAX study from the Danish Diet, Cancer and Health - Next Generations (DCH-NG) cohort. Results showed that individuals with higher total polyphenol and phenolic acid intakes, were less likely to have MetS. Furthermore, for cardiovascular risk factors, intakes of total polyphenols, flavonoids and phenolic acids were associated with a lower risk of higher systolic blood pressure and lower high-density lipoprotein cholesterol. Authors conclude by suggesting that intervention studies should be undertaken to establish whether a polyphenol-rich diet can improve some cardiometabolic risk factors and can reduce or delay the onset of cardiometabolic diseases in free-living populations.
Abstract
BACKGROUND AND AIMS Polyphenol-rich foods have beneficial properties that may lower cardiometabolic risk. We aimed to prospectively investigate the relationship between intakes of dietary polyphenols, and metabolic syndrome (MetS) and its components, in 676 Danish residents from the MAX study, a subcohort of the Danish Diet, Cancer and Health-Next Generations (DCH-NG) cohort. METHODS AND RESULTS Dietary data were collected using web-based 24-h dietary recalls over one year (at baseline, and at 6 and 12 months). The Phenol-Explorer database was used to estimate dietary polyphenol intake. Clinical variables were also collected at the same time point. Generalized linear mixed models were used to investigate relationships between polyphenol intake and MetS. Participants had a mean age of 43.9y, a mean total polyphenol intake of 1368 mg/day, and 75 (11.6%) had MetS at baseline. Compared to individuals with MetS in Q1 and after adjusting for age, sex, lifestyle and dietary confounders, those in Q4 - for total polyphenols, flavonoids and phenolic acids-had a 50% [OR (95% CI): 0.50 (0.27, 0.91)], 51% [0.49 (0.26, 0.91)] and 45% [0.55 (0.30, 1.00)] lower odds of MetS, respectively. Higher total polyphenols, flavonoids and phenolic acids intakes as continuous variable were associated with lower risk for elevated systolic blood pressure (SBP) and low high-density lipoprotein cholesterol (HDL-c) (p < 0.05). CONCLUSIONS Total polyphenol, flavonoid and phenolic acid intakes were associated with lower odds of MetS. These intakes were also consistently and significantly associated with a lower risk for higher SBP and lower HDL-c concentrations.

Plain language summary
Carrying excess weight during childhood and adolescence is believed to be a major risk factor for the development of cardiometabolic diseases in adulthood. Furthermore, high serum leptin concentrations are strictly related to pubertal development, and therefore have an impact on the age at which menarche occurs. The aim of this study was to analyse the relationship between age at menarche and healthy/unhealthy metabolic profiles, relating them to different body mass index categories, waist circumference, and serum leptin concentrations in female adolescents. This study is a cross-sectional study which investigated one hundred and thirty-nine, girls aged 10 to 19 years, who had gone through menarche. Results show that there is a relationship between early menarche and high serum leptin concentrations particularly in the metabolically unhealthy phenotype adolescent girls who have different body mass indices. Authors conclude that it is important that age of menarche, serum leptin levels and metabolic phenotypes of children and adolescents are analysed during clinical practice, in order to formulate strategies to prevent the development of cardiometabolic diseases in adulthood.
Abstract
Objective: to analyze the relationship of age at menarche and leptin with the metabolically healthy (MH) and metabolically unhealthy (MUH) phenotypes in adolescent girls in different body mass index (BMI) categories. Method: an observational and cross-sectional study consisting of 139 female adolescents attended to at the Adolescent Reference Center in Macaé, Rio de Janeiro. Menarche was classified as early (EM) when the first menstruation occurred at or before 11 years of age; normal menarche (NM) was categorized at ages 12 to 14; menarche was considered late (LM) when it occurred at age 15 or older. The factors required to ascertain the subjects' phenotype, as well as their leptin levels, weight, and height, were measured and their BMIs were calculated. The girls were classified as MH or MUH based on the NCEP-ATP III criteria as adapted for children and adolescents. Results: 82 % (n = 114) of the girls were classified as MH and 18 % (n = 25) as MUH. Mean age at menarche was 11.79 ± 1.39 years. There was a higher prevalence of MUH amongst the girls who had EM (p = 0.04). A higher inadequacy of serum leptin concentrations was found in girls who had EM (p = 0.05) and in those classified as MUH (p = 0.01). The adolescents who were severely obese exhibited inadequate leptin levels (p < 0.01) and had gone through EM (p = 0.02). A total of 8.1 % (n = 7) of the normal-weight girls were classified as MUH, and 29.4 % (n = 5) of those who were severely obese were classified as MH (p < 0.01). Conclusion: early menarche and high serum leptin concentrations are related with the MUH phenotype in adolescent girls in different BMI categories. Objetivo: analizar la relación de la edad de la menarquia y los niveles de leptina con los fenotipos metabólicamente saludables (MS) y metabólicamente no saludables (MNS) en adolescentes de diferentes categorías de índice de masa corporal (IMC). Método: estudio observacional y transversal compuesto por 139 adolescentes de sexo feminino, atendidas en el Centro de Referencia para Adolescentes de Macaé, Río de Janeiro. La menarquia se clasificó como precoz (MP) cuando se produjo la primera menstruación a o antes de los 11 años de edad; la menarquia normal (MN) se clasificó como aquella sucedida a la edad de 12 a 14 años; la menarquia se consideró tardía (MT) cuando ocurrió a los 15 años o más. Se midieron los factores necesarios para determinar el fenotipo de los sujetos, y se midieron sus niveles de leptina, peso y altura, y se calculó su IMC. Las adolescentes se clasificaron como MS y MNS según los criterios de NCEP-ATP III, adaptados para niños y adolescentes. Resultados: el 82 % (n = 114) de las adolescentes se clasificaron como MH y el 18 % (n = 25) como MUH. La edad media de la menarquia fue de 11,79 ± 1,39 años. Hubo una mayor prevalencia de MUH entre las adolescentes que tenían MP (p = 0,04). Se encontró una mayor insuficiencia de las concentraciones séricas de leptina en las adolescentes que tenían MP (p = 0,05) y en aquellas clasificadas como MNS (p = 0,01). Las adolescentes que eran severamente obesas exhibieron niveles inadecuados de leptina (p < 0,01) y habían pasado por una MP (p = 0,02). El 8,1 % (n = 7) de las adolescentes de peso normal se clasificaron como MNS y el 29,4 % (n = 5) de las que eran severamente obesas se clasificaron como MS (p < 0,01). Conclusión: la menarquia temprana y las altas concentraciones séricas de leptina están relacionadas con el fenotipo MNS en las adolescentes de diferentes categorías de IMC.

Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is common in people with obesity and is characterised by high amounts of fat stored in the liver. Diet and exercise are the standard treatments, however recent studies have indicated that the gut microbiota may have an important role. This randomised control trial of 140 patients with NAFLD, aimed to assess the effect of probiotics when added to standard therapy for 3 months. The results showed that although gut microbiota, some aspects of liver function, blood lipids and blood sugars were all improved in individuals on standard therapy, there were additional improvements in those on standard therapy plus probiotics. It was concluded that although standard therapy alone is adequate to improve NAFLD, probiotics plus standard therapy was superior to standard therapy alone and effective in treatment of NAFLD. This study could be used by health professionals to justify the addition of probiotics to standard therapy to further improve NAFLD outcomes.
Abstract
To investigate the effects of probiotics on liver function, glucose and lipids metabolism, and hepatic fatty deposition in patients with non-alcoholic fatty liver disease (NAFLD).Totally 140 NAFLD cases diagnosed in our hospital from March 2017 to March 2019 were randomly divided into the observation group and control group, 70 cases in each. The control group received the diet and exercise therapy, while the observation group received oral probiotics based on the control group, and the intervention in 2 groups lasted for 3 months. The indexes of liver function, glucose and lipids metabolism, NAFLD activity score (NAS), and conditions of fecal flora in 2 groups were compared before and after the treatment.Before the treatment, there were no significant differences on alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamine transferase (GGT), total bilirubin (TBIL), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), insulin resistance index (HOMA-IR), NAFLD activity score (NAS), and conditions of fecal flora in 2 groups (P > .05). After the treatment, ALT, AST, GGT, TC, TG, HOMA-IR, NAS, and conditions of fecal flora in the observation group were better than those in the control group, and the observation group was better after treatment than before. All these above differences were statistically significant (P < .05).Probiotics can improve some liver functions, glucose and lipids metabolism, hepatic fatty deposition in patients with NAFLD, which will enhance the therapeutic effects of NAFLD.

Plain language summary
In adolescents, severe obesity may lead to a high risk of premature mortality and morbidity in adult life. Increased vitamin D deficiency (VDD) occurs together with obesity. The main aim of this study was to assess the nutritional status of vitamin D and metabolic profile in adolescents and adults with obesity. The study is a comparative observational study which included 128 individuals. A total of 60 participants comprised the adolescent group (G1), (63.3% female) whereas 68 participants comprised the adult group (G2), (75% female). Results indicate: - a high prevalence of inadequacy of Vitamin D in both groups. - a trend of association of elevated blood glucose with the inadequacy of Vitamin D in the adolescent group. - a high prevalence of VDD and non-alcoholic fatty liver disease in both groups. - no relationship between Vitamin D and high blood pressure or metabolic syndrome in any of the groups evaluated. Authors conclude that strategies for the prevention and control of obesity and for the fight against the inadequacy of the nutritional status of vitamin D should be developed.
Abstract
INTRODUCTION increased vitamin D deficiency occurs together with obesity and the association between these conditions has been observed. OBJECTIVE to assess the nutritional status of vitamin D and metabolic profile in adolescents and adults with obesity, and the relationship between complications arising from severe class of obesity with vitamin D nutritional status, and to compare the differences between these groups. METHODS observational comparative study. Population comprises adolescents and adults with severe obesity. Waist circumference (WC) and body mass index (BMI) were measured. Analysis of vitamin D (25(OH)D), lipid profile, C-reactive protein (CRP), blood glucose, fasting insulinemia, insulin sensitivity, blood pressure and diagnoses of nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome (MS) were performed. RESULTS a total of 60 adolescents (G1) and 68 adults (G2) were evaluated. The percentage of vitamin D inadequacy was observed in 90% in G1 and 79.4% in G2. There was a negative and significant correlation of BMI with the values of 25(OH)D in the group of adults (r = -0.244; p = 0.045). Individuals with inadequacy of vitamin D showed higher values of CRP in both groups (p = 0.000). HOMA-IR showed a negative correlation with 25(OH)D in G1 (r = -0.832; p = 0.000) and G2 (r = -0.589; p = 0.000). The inadequacy of this vitamin showed association with high total cholesterol in G1 (p = 0.029) and higher values of LDL-c in G2 (p = 0.003). CONCLUSION high prevalence of deficiency and insufficiency of vitamin D were observed, associated with metabolic changes both in obese adults and adolescents. It is necessary to develop strategies for the prevention and control of obesity and vitamin D deficiency.

Plain language summary
Physical activity has been shown to considerably reduce the burden of several non-communicable disorders (are diseases of long duration and generally slow progression), such as heart disease, stroke, diabetes, and breast and colon cancers. The aim of the study is to estimate the prevalence of physical activity among a mixed group of patients with psychiatric illnesses in Saudi Arabia. Furthermore, the study sought to evaluate the associations between physical activity, patients with different psychiatric diagnoses and the use of psychotropic medications. The study is a cross-sectional observational study that recruited 1185 patients seeking psychiatric advice, with an average age of 38.0±13.0 years. Results indicate a low prevalence of physical activity in a large, mixed sample of patients with psychiatric illnesses in both inpatient and outpatient settings in Saudi Arabia. Authors conclude that physical activity levels vary according to the type of psychiatric disease and the medications used. They outline that it is important to assess the physical activity status in patients with psychiatric illnesses and promote physical activity programs among psychiatric patients.
Abstract
OBJECTIVES To estimate prevalence of physical activity and its associations with various psychiatric disorders and the use of psychotropic medications. METHODS A cross-sectional observational study was carried out between July 2012 and June 2014. Patients were enrolled from a number of hospitals located in 5 regions of the Kingdom of Saudi Arabia. RESULTS A total of 1185 patients were included in current analysis: 796 were outpatients, and 389 were inpatients. Out of 1,185 patients, 153 (12.9%) were physically active. Much higher rates of physical activity were reported among males than females (15.9% versus 9.6%, p less than 0.001). According to the univariate analysis, higher rates of physical activity were positively correlated with primary bipolar disorders, the use of antianxiety medications and, to a lesser extent, use of antipsychotic medications, but they were negatively correlated with primary anxiety disorders, use of antidepressant medications, and use of multiple psychotropic medications. The associations between physical activity and primary bipolar disorders (odds ratio [OR]=2.47, p=0.002), use of antianxiety medications (OR=3.58, p=0.003), and use of multiple psychotropic medications (OR=0.33, p less than 0.001) remained significant after adjusting for demographic and clinical characteristics. CONCLUSION We report a variable but generally low prevalence of physical activity among a large, mixed sample of psychiatric patients in Saudi Arabia. These findings may highlight the importance of assessing physical activity status of psychiatric patients and the critical need for physical activity promotion programs among this group of disadvantaged patients.
