Abstract
BACKGROUND Rosacea is a common inflammatory skin disorder. Several studies, but not all, have suggested a high prevalence of cardiovascular diseases (CVDs) in rosacea patients. This study is aimed at investigating the association between rosacea and CVDs and related risk factors. METHODS We performed a literature search through PubMed, Embase, and Web of Science databases, from their respective inception to December 21, 2019. Two reviewers independently screened the articles, extracted data, and performed analysis, following the PRISMA guidelines. Odds ratios (OR) or standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated for outcomes. The included studies' quality was evaluated using the Newcastle Ottawa Scale (NOS). RESULTS The final meta-analysis included ten studies. The pooled analysis found no association between rosacea prevalence and the incidence of CVDs (OR 0.97; 95% CI 0.86-1.10). Rosacea was found to be significantly associated with several risk factors for CVDs (OR 1.17; 95% CI 1.05-1.31), including hypertension (OR 1.17; 95% CI 1.02-1.35), dyslipidemia (OR 1.34; 95% CI 1.00-1.79), and metabolic syndrome (OR 1.72; 95% CI 1.09-2.72). However, no association was found between rosacea and diabetes mellitus (OR 0.98; 95% CI 0.82-1.16). Among the biological parameters, a significant association was found between rosacea and total cholesterol (SMD = 0.40; 95% CI = -0.00, 0.81; p < 0.05), low-density lipoprotein cholesterol (SMD = 0.28; 95% CI = 0.01, 0.56; p < 0.05), and C-reactive protein (CRP) (SMD = 0.25; 95% CI = 0.10, 0.41; p < 0.05). We found no association between rosacea and high-density lipoprotein cholesterol (SMD = 0.00; 95% CI = -0.18, 0.18; p = 0.968) or triglycerides (SMD = 0.10; 95% CI = -0.04, 0.24; p = 0.171). CONCLUSIONS Although no significant association was found between rosacea and CVDs, rosacea was found to be associated with several of related risk factors. Patients with rosacea should pay more attention to identifiable CVD risk factors, especially those related to inflammatory and metabolic disorders.

Abstract
OBJECTIVES To evaluate the effect of Lactobacillus casei 01 on dietary intake, body weight, and glycemic control in patients with T2DM. METHOD Forty patients with T2DM (n = 20 for each group) were assigned into two groups in present trial. The patients in the probiotic group received a daily capsule containing a minimum of 108 CFU of L. casei 01 for 8 week. The placebo group took capsules filled with maltodextrin for the same time period. Dietary intake questionnaires and anthropometric measurements were collected, and the participants were assessed by an endocrinologist at baseline and at the end of the trial. RESULTS Lactobacillus casei 01 supplementation significantly decreased total energy, carbohydrate, fat, and protein intake compared with placebo (p = 0.001, p = 0.002, p = 0.009, p = 0.001; respectively). Moreover weight, BMI, and waist circumference were significantly decreased in intervention group compared with placebo group (p < 0.001; p < 0.001; p = 0.029; respectively). In comparison with placebo group serum fetuin-A level, fasting blood sugar, insulin concentration, and insulin resistance were significantly decreased (p = 0.023, p =0.013, p = 0.028; p = 0.007; respectively), and serum SIRT1 level was significantly increased (p = 0.040) in intervention group. CONCLUSIONS Lactobacillus casei 01 supplementation affected dietary intake and body weight in a way that improved fetuin-A and SIRT1 levels and glycemic response in subjects with T2DM. Affecting the fetuin-A and SIRT1 levels introduces a new known mechanism of probiotic action in diabetes management.

Abstract
OBJECTIVE To compare clinical and metabolic profiles between N-acetylcysteine and l-carnitine among women with clomiphene citrate (CC)-resistant polycystic ovary syndrome (PCOS). METHODS A randomized trial at Zagazig University between January 2017 and March 2018. Women with CC-resistant PCOS were allocated randomly to receive CC plus N-acetylcysteine or CC plus l-carnitine. The primary outcome was clinical pregnancy rate; secondary outcomes were ovulation rate and metabolic changes. RESULTS Overall, 162 women completed the study (N-acetylcysteine group, n=82; l-carnitine group, n=80). After 3 months, there was no difference in pregnancy (P=0.15), ovulation (P=0.21), or spontaneous abortion (P=0.11) rates between the two groups. There was no significant decrease in BMI in either group (both P>0.05). There were improvements in menstrual pattern, follicle-stimulating hormone, luteinizing hormone, free testosterone, and insulin resistance markers in both groups (all P<0.05). An improvement in lipid profile was observed only in the l-carnitine group (P<0.001). N-Acetylcysteine treatment led to significantly greater improvement in free testosterone and insulin resistance parameters as compared with l-carnitine (all P<0.05). CONCLUSIONS Both N-acetylcysteine and l-carnitine were equally effective in improving pregnancy and ovulation rates among women with CC-resistant PCOS. However, N-acetylcysteine was superior in ameliorating insulin resistance and only l-carnitine improved lipid profile. TRIAL REGISTRATION ClinicalTrials.gov: NCT03164421.

Abstract
PURPOSE OF THE STUDY There was inconsistent evidence about the benefit of vitamin D plus evening primrose oil (EPO) supplement intake on lipid profiles and reduced oxidative stress among women with polycystic ovary syndrome (PCOS). The current study was performed to evaluate the effects of vitamin D plus EPO supplementation on lipid profiles and biomarkers of oxidative stress in vitamin D-deficient women with PCOS. MATERIALS AND METHODS This randomized, double-blind, placebo-controlled trial was performed among 60 vitamin D-deficient women with PCOS. Participants were randomly assigned into two groups to receive either 1000 IU vitamin D3 plus 1000 mg EPO (n = 30) or placebo (n = 30) for 12 weeks. Metabolic profiles were quantified at baseline and after the 12-week intervention. RESULTS Compared with the placebo group, women in vitamin D and EPO co-supplementation group had significant increases in serum 25-hydroxyvitamin D (25(OH)D) (+10.7 ± 8.4 vs. -0.5 ± 1.6 ng/mL, p < 0.001) and plasma total glutathione (GSH) (+62.7 ± 58.0 vs. -0.7 ± 122.7 µmol/L, p = 0.01), while there were significant decreases in triglycerides (-7.3 ± 23.8 vs. +6.9 ± 26.3 mg/dL, p = 0.03), very low-density lipoprotein (VLDL) cholesterol levels (-1.5 ± 4.7 vs. +1.4 ± 5.3 mg/dL, p = 0.03), total/high-density lipoprotein cholesterol ratio (-0.3 ± 0.4 vs. -0.02 ± 0.4, p = 0.02), and malondialdehyde (MDA) concentration (-0.4 ± 0.4 vs. +0.5 ± 1.8 µmol/L, p = 0.008). CONCLUSION Overall, vitamin D and EPO co-supplementation for 12 weeks among vitamin D-deficient women with PCOS significantly improved triglycerides, VLDL cholesterol, GSH, and MDA levels.

Abstract
OBJECTIVE To assess the effects of a 12-week gardening, nutrition, and cooking intervention ("LA Sprouts") on dietary intake, obesity parameters, and metabolic disease risk among low-income, primarily Hispanic/Latino youth in Los Angeles. METHODS The randomized controlled trial involved four elementary schools [two schools randomized to intervention (172 third-through fifth-grade students); two schools randomized to control (147 third-through fifth-grade students)]. Classes were taught in 90-minute sessions once a week to each grade level for 12 weeks. Data collected at pre- and postintervention included dietary intake via food frequency questionnaire (FFQ), anthropometric measures [BMI, waist circumference (WC)], body fat, and fasting blood samples. RESULTS LA Sprouts participants had significantly greater reductions in BMI z-scores (0.1-vs. 0.04-point decrease, respectively; P = 0.01) and WC (-1.2 cm vs. no change; P < 0.001). Fewer LA Sprouts participants had the metabolic syndrome (MetSyn) after the intervention than before, while the number of controls with MetSyn increased. LA Sprouts participants had improvements in dietary fiber intake (+3.5% vs. -15.5%; P = 0.04) and less decreases in vegetable intake (-3.6% vs. -26.4%; P = 0.04). Change in fruit intake before and after the intervention did not significantly differ between LA Sprouts and control subjects. CONCLUSIONS LA Sprouts was effective in reducing obesity and metabolic risk.

A comprehensive review on metabolic syndrome.
Kaur, J
Cardiology research and practice. 2014;:943162
Abstract
Metabolic syndrome is defined by a constellation of interconnected physiological, biochemical, clinical, and metabolic factors that directly increases the risk of cardiovascular disease, type 2 diabetes mellitus, and all cause mortality. Insulin resistance, visceral adiposity, atherogenic dyslipidemia, endothelial dysfunction, genetic susceptibility, elevated blood pressure, hypercoagulable state, and chronic stress are the several factors which constitute the syndrome. Chronic inflammation is known to be associated with visceral obesity and insulin resistance which is characterized by production of abnormal adipocytokines such as tumor necrosis factor α , interleukin-1 (IL-1), IL-6, leptin, and adiponectin. The interaction between components of the clinical phenotype of the syndrome with its biological phenotype (insulin resistance, dyslipidemia, etc.) contributes to the development of a proinflammatory state and further a chronic, subclinical vascular inflammation which modulates and results in atherosclerotic processes. Lifestyle modification remains the initial intervention of choice for such population. Modern lifestyle modification therapy combines specific recommendations on diet and exercise with behavioural strategies. Pharmacological treatment should be considered for those whose risk factors are not adequately reduced with lifestyle changes. This review provides summary of literature related to the syndrome's definition, epidemiology, underlying pathogenesis, and treatment approaches of each of the risk factors comprising metabolic syndrome.

BioMed research international. 2014;:786463
Abstract
Copper (Cu) is an important trace element in humans; it plays a role as a cofactor for numerous enzymes and other proteins crucial for respiration, iron transport, metabolism, cell growth, and hemostasis. Natural copper comprises two stable isotopes, (63)Cu and (65)Cu, and 5 principal radioisotopes for molecular imaging applications ((60)Cu, (61)Cu, (62)Cu, and (64)Cu) and in vivo targeted radiation therapy ((64)Cu and (67)Cu). The two potential ways to produce Cu radioisotopes concern the use of the cyclotron or the reactor. A noncopper target is used to produce noncarrier-added Cu thanks to a chemical separation from the target material using ion exchange chromatography achieving a high amount of radioactivity with the lowest possible amount of nonradioactive isotopes. In recent years, Cu isotopes have been linked to antibodies, proteins, peptides, and nanoparticles for preclinical and clinical research; pathological conditions that influence Cu metabolism such as Menkes syndrome, Wilson disease, inflammation, tumor growth, metastasis, angiogenesis, and drug resistance have been studied. We aim to discuss all Cu radioisotopes application focusing on (64)Cu and in particular its form (64)CuCl2 that seems to be the most promising for its half-life, radiation emissions, and stability with chelators, allowing several applications in oncological and nononcological fields.

Plain language summary
The traditional Mediterranean diet has been shown to have cardiovascular protective effects based on previous observational cohort studies and a secondary prevention trial. While the mechanism for the beneficial effects of this diet have not been established, small trials have suggested that it fosters favourable changes in the pathways involved in cardio-metabolic disease. The aim of this randomised trial was to test the efficacy of two variations of the Mediterranean diet on reducing the incidence of cardiovascular events. These diets included Mediterranean diet supplemented with extra-virgin olive oil or mixed nuts, and a control diet (advised to reduce dietary fat). The study included 7,447 participants aged 55-80 and participants were followed for an average of 4.8 years. Both groups showed good adherence to the diets. The findings of this study showed that among persons at high cardiovascular risk, both variations of the Mediterranean diet resulted to a significant risk reduction of cardiovascular events, notably stroke. Based on this study, the authors’ conclusions support the benefits of the Mediterranean diet for the primary prevention of cardiovascular disease.
Abstract
BACKGROUND Observational cohort studies and a secondary prevention trial have shown an inverse association between adherence to the Mediterranean diet and cardiovascular risk. We conducted a randomized trial of this diet pattern for the primary prevention of cardiovascular events. METHODS In a multicenter trial in Spain, we randomly assigned participants who were at high cardiovascular risk, but with no cardiovascular disease at enrollment, to one of three diets: a Mediterranean diet supplemented with extra-virgin olive oil, a Mediterranean diet supplemented with mixed nuts, or a control diet (advice to reduce dietary fat). Participants received quarterly individual and group educational sessions and, depending on group assignment, free provision of extra-virgin olive oil, mixed nuts, or small nonfood gifts. The primary end point was the rate of major cardiovascular events (myocardial infarction, stroke, or death from cardiovascular causes). On the basis of the results of an interim analysis, the trial was stopped after a median follow-up of 4.8 years. RESULTS A total of 7447 persons were enrolled (age range, 55 to 80 years); 57% were women. The two Mediterranean-diet groups had good adherence to the intervention, according to self-reported intake and biomarker analyses. A primary end-point event occurred in 288 participants. The multivariable-adjusted hazard ratios were 0.70 (95% confidence interval [CI], 0.54 to 0.92) and 0.72 (95% CI, 0.54 to 0.96) for the group assigned to a Mediterranean diet with extra-virgin olive oil (96 events) and the group assigned to a Mediterranean diet with nuts (83 events), respectively, versus the control group (109 events). No diet-related adverse effects were reported. CONCLUSIONS Among persons at high cardiovascular risk, a Mediterranean diet supplemented with extra-virgin olive oil or nuts reduced the incidence of major cardiovascular events.

Low birth weight: causes and consequences.
Negrato, CA, Gomes, MB
Diabetology & metabolic syndrome. 2013;:49
Abstract
During our phylogenetic evolution we have selected genes, the so called thrifty genes, that can help to maximize the amount of energy stored from every consumed calorie. An imbalance in the amount of stored calories can lead to many diseases. In the early 80's the distinguished English epidemiologist David Barker, formulated a hypothesis suggesting that many events that occur during the intrauterine life and early in infancy can influence the occurrence of many diseases that will develop in adulthood. This theory proposes that under-nutrition and other insult or adverse stimulus in utero and during infancy can permanently change the body's structure, physiology and metabolism. The lasting or lifelong effects of under-nutrition will depend on the period in the development at which it occurs. The clues that led Barker to his conclusions started to be discovered when he was studying the temporal trends in the incidence of ischemic heart disease in England and Wales. Examining data found in The Hertfordshire records, collected in the beginning of the last century, he found that the rates of mortality by ischemic heart disease was much higher in children born in less affluent counties and mostly in those with low birth weight. After his initial findings a myriad of diseases have been found to be linked to low birth weight and under-nutrition in utero and in the neonatal period. These diseases were then nominated adult diseases with fetal origin. Epidemiological studies that led to these findings suggest that in utero and early postnatal life have critical importance for long-term programming of health and disease, opening unique chances for primary prevention of chronic diseases.

Abstract
BACKGROUND Obstructive sleep apnea is associated with an increased prevalence of the metabolic syndrome and its components. It is unclear whether treatment of obstructive sleep apnea syndrome with continuous positive airway pressure (CPAP) would modify these outcomes. METHODS In our double-blind, placebo-controlled trial, we randomly assigned patients with obstructive sleep apnea syndrome to undergo 3 months of therapeutic CPAP followed by 3 months of sham CPAP, or vice versa, with a washout period of 1 month in between. Before and after each intervention, we obtained measurements of anthropometric variables, blood pressure, fasting blood glucose levels, insulin resistance (with the use of homeostasis model assessment), fasting blood lipid profile, glycated hemoglobin levels, carotid intima-media thickness, and visceral fat. The metabolic syndrome was defined according to National Cholesterol Education Program Adult Treatment Panel III criteria, with Asian cutoff values for abdominal obesity. RESULTS A total of 86 patients completed the study, 75 (87%) of whom had the metabolic syndrome. CPAP treatment (vs. sham CPAP) was associated with significant mean decreases in systolic blood pressure (3.9 mm Hg; 95% confidence interval [CI], 1.4 to 6.4; P=0.001), diastolic blood pressure (2.5 mm Hg; 95% CI, 0.9 to 4.1; P<0.001), serum total cholesterol (13.3 mg per deciliter; 95% CI, 5.3 to 21.3; P=0.005), non-high-density lipoprotein cholesterol (13.3 mg per deciliter; 95% CI, 4.8 to 21.8; P=0.009), low-density lipoprotein cholesterol (9.6 mg per deciliter; 95% CI, 2.5 to 16.7; P=0.008), triglycerides (18.7 mg per deciliter; 95% CI, 4.3 to 41.6; P=0.02), and glycated hemoglobin (0.2%; 95% CI, 0.1 to 0.4; P=0.003). The frequency of the metabolic syndrome was reduced after CPAP therapy (reversal found in 11 of 86 patients [13%] undergoing CPAP therapy vs. 1 of 86 [1%] undergoing sham CPAP). Accelerated hypertension developed 1 patient receiving CPAP therapy first, intolerance to CPAP developed in 2 others, and another patient declined to continue sham CPAP. CONCLUSIONS In patients with moderate-to-severe obstructive sleep apnea syndrome, 3 months of CPAP therapy lowers blood pressure and partially reverses metabolic abnormalities.
