Abstract
BACKGROUND Individuals who were born prematurely (PT), with low birth weight (LBW), or small for gestational age (SGA) appear to present a set of permanent changes that make them more susceptible to develop chronic non-communicable diseases (CNCD) in adult life. AIM: Investigating the association between PT birth, LBW or SGA at birth and CNCD incidence in adult life. METHODS Systematic review with meta-analysis of studies available in three databases - two of them are official (PubMed and Web of Science) and one is gray literature (OpenGrey) - based on pre-established search and eligibility criteria. RESULTS Sixty-four studies were included in the review, 93.7% of them only investigated one of the exposure variables (46.7% LBW, 35.0% PT and 18.3% SGA at birth), whereas 6.3% investigated more than one exposure variable (50.0% LBW and PT; 50.0% SGA and PT). There was association among all exposure variables in the following outcomes: cardiometabolic (CMD) and glycidic metabolism (GMD) disorders, changes in body composition and risk of developing metabolic syndrome (MS). Female sex was identified as risk factor in the exposure-outcome association. Eighteen (18) articles were included in the meta-analysis. There was positive association between LBW and incidence of CMD (OR: 1.25 [95%CI: 1.11; 1.41]; 07 studies), GMD (OR: 1.70 [95%CI: 1.25; 2.30]; 03 studies) and MS (OR: 1.75 [95%CI: 1.27; 2.40]; 02 studies) in adult life. PT was positively associated with CMD (OR: 1.38 [95%CI: 1.27; 1.51]; 05 studies). CONCLUSIONS LBW and PT are associated with CMD and GMD development, as well as with the risk of developing MS in adult life.

Abstract
BACKGROUND AND AIMS The present systematic review and meta-analysis was conducted to investigate the effect of cinnamon supplementation on blood pressure and anthropometric indices in patients with type 2 diabetes. METHODS PubMed, Embase, Scopus, Web of Science and Cochrane Library were systematically searched to find relevant records up to 22 August 2019. Standard mean difference (SMD) and 95% confidence interval (CI) were used to evaluate the effect of cinnamon supplementation on the outcomes of this study. In the case of heterogeneity, fixed and random effect models were used. The obtained data were analyzed by Stata 13. After excluding irrelevant records, 9 eligible articles were included. RESULTS This meta-analysis found a significant reduction in systolic blood pressure (SBP) (SMD: -0.532, 95% CI: [-1.032, -0.033], P = 0.037) and diastolic blood pressure (DBP) (SMD: -0.681, 95% CI: [-1.297, -0.065], P = 0.030) of patients with type 2 diabetes following cinnamon supplementation. Based on the results of the present study, cinnamon supplementation had no significant effect on the body weight (BW) (SMD: -0.309, 95% CI: [-0.793, 0.175], P = 0.211), body mass index (BMI) (SMD: -0.550, 95% CI: [-1.244, 0.144], P = 0.120). and waist circumference (WC) (SMD: -0.235, 95% CI: [-0.518, 0.047], P = 0.103). CONCLUSIONS Cinnamon supplementation significantly decreased SBP and DBP of patients with type 2 diabetes. Although cinnamon intake caused changes in anthropometric parameters, the observed changes were not statistically significant.

Abstract
Genistein (4',5,7-trihydroxyisoflavone) is a phytoestrogen with potential health benefits in the prevention of cardiovascular disease. However, the evidence regarding its effects on hypertension has not been conclusive. Therefore, we examined the impact of oral genistein supplementation on systolic blood pressure (SBP) and diastolic blood pressure (DBP) via a systematic review and meta-analysis of randomized controlled trials (RCTs). PubMed, ISI Web of Science, Scopus and the Cochrane library databases (until August 2019) were searched to identify potential RCTs with information on genistein supplementation and hypertension. Weighted Mean Difference (WMD) was pooled using a random-effects model. Pooling four RCTs (four treatment arms) together did not show any significant reduction of SBP (WMD: -5.32 mmHg, 95% CI: -14.59 to 3.96) and DBP (WMD: -2.06 mmHg, 95% CI: -6.41 to 2.28) compared to that of the placebo group. However, subgroup analysis by intervention duration suggested that more than 6 months genistein supplementation in metabolic syndrome patients can significantly decrease SBP (WMD: -13.73 mmHg, 95% CI: -18.10 to -9.37) and DBP (WMD: -5.18 mmHg, 95% CI: -6.62 to -3.74). Generally, present study indicated that genistein supplementation had no effect on hypertension, but it seems that longer intervention duration of more than 6 months especially among metabolic syndrome patients may lead to the effectiveness of genistein.

Abstract
BACKGROUND AND AIMS Oxidative stress (OS) is one of the main risk factors for several chronic diseases. The Dietary Approaches to Stop Hypertension (DASH) contain many antioxidants and may contribute to managing OS. OBJECTIVE To perform a systematic review and meta-analysis to examine the impacts of the DASH diet on OS parameters. METHODS A comprehensive electronic search in MEDLINE, Scopus, EMBASE, and the Cochrane Central Register of Controlled Trials was performed through September 2020 to find related studies evaluating the impact of the DASH diet on OS parameters. Standardized mean differences were pooled using random-effects meta-analysis. RESULTS Eight studies with a total of 317 subjects met our inclusion criteria. Four studies included in meta-analysis model with 200 participants (100 in treatment and 100 in control group). The DASH diet was associated with a statistically significant decrease in malondialdehyde (MDA) (SMD: -0.53; 95% CI: -0.89, -0.16; I2 = 42.1%), and a significant increase in glutathione (GSH) (SMD: 0.83; 95% CI: 0.36, 1.03; I2 = 42.1%). Meta-analysis found no statistically significant effect of DASH diet on nitric oxide (NO) (SMD: -1.40; 95% CI: -0.12, 1.93; I2 = 92.6%) or total antioxidant capacity (TAC) levels (SMD: 0.95; 95% CI: -0.10, 1.99; I2 = 87.6%). CONCLUSION Our results demonstrated that a DASH diet could significantly increase GSH and decrease MDA levels. Furthermore, there is a trend to improve TAC, NO, and f2-isoprostanes by the adherence to the DASH diet. However, long-term, large sample size and well-designed randomized clinical trials are still needed to draw concrete conclusions about DASH diet's effects on OS parameters.

Abstract
BACKGROUND Psoriasis is a very prevalent systemic chronic inflammatory disease. Major cardiovascular events are the main cause of mortality in these patients which suggests an association between psoriasis and traditional cardiovascular risk factors. OBJECTIVE To identify classic cardiovascular risk factors and metabolic syndrome (MS) in patients with psoriasis, their possible association with its severity and compare it with the non-psoriatic population. METHODS This is an observational and cross-sectional population study in Lleida (Spain) from a joint hospital/primary care database. RESULTS The database comprised 398 701 individuals. There were 6868 cases registered as psoriasis (1.7%), and 499 of them (7.3%) were classified as moderate-severe psoriasis. Patients with psoriasis had a higher prevalence of traditional cardiovascular risk factors than non-psoriatic population: diabetes mellitus 2 (13.9% vs 7.4%, OR 2.01), dyslipidaemia (28.8% vs 17.4%, OR 1.92), arterial hypertension (31.2% vs 19.0%, OR 1.93), obesity (33.7% vs 28.1%, OR 1.30), altered fasting basal glycaemia (21.4% vs 15.1%, OR 1.54), low cholesterol HDL (38.1% vs 32.3%, OR 1.29), hypertriglyceridaemia (45.7% vs 35.2%, OR 1.55) and high waist circumference (75.7% vs 72.3%, OR 1.19). MS was more prevalent in psoriatic patients (28.3% vs 15.1%, OR 2.21), and cardiovascular risk factors were similar between psoriasis severity groups. Psoriatic patients had a higher prevalence of ischaemic heart disease (3.3% vs 1.8%, OR 1.87) and vascular cerebral accidents (1.8% vs 1.2%, OR 1.55). A model for MS showed a significant nonlinear relationship with age and sex and significant differences between patients with and without psoriasis. CONCLUSION We found statistically significant differences in relation to the prevalence of cardiovascular risk factors, MS and major cardiovascular events in psoriatic patients. However, differences were not seen between psoriasis severity groups. Our work reinforces the need for a multidisciplinary approach and close monitoring of cardiovascular risk factors in these patients to prevent a cardiovascular event.

Abstract
BACKGROUND Reduced nocturnal fall (non-dipping) of blood pressure (BP) is a predictor of cardiovascular target organ damage. No genome-wide association studies (GWAS) on BP dipping have been previously reported. METHODS To study genetic variation affecting BP dipping, we conducted a GWAS in Genetics of Drug Responsiveness in Essential Hypertension (GENRES) cohort (n = 204) using the mean night-to-day BP ratio from up to four ambulatory BP recordings conducted on placebo. Associations with P < 1 × 10- 5 were further tested in two independent cohorts: Haemodynamics in Primary and Secondary Hypertension (DYNAMIC) (n = 183) and Dietary, Lifestyle and Genetic determinants of Obesity and Metabolic Syndrome (DILGOM) (n = 180). We also tested the genome-wide significant single nucleotide polymorphism (SNP) for association with left ventricular hypertrophy in GENRES. RESULTS In GENRES GWAS, rs4905794 near BCL11B achieved genome-wide significance (β = - 4.8%, P = 9.6 × 10- 9 for systolic and β = - 4.3%, P = 2.2 × 10- 6 for diastolic night-to-day BP ratio). Seven additional SNPs in five loci had P values < 1 × 10- 5. The association of rs4905794 did not significantly replicate, even though in DYNAMIC the effect was in the same direction (β = - 0.8%, P = 0.4 for systolic and β = - 1.6%, P = 0.13 for diastolic night-to-day BP ratio). In GENRES, the associations remained significant even during administration of four different antihypertensive drugs. In separate analysis in GENRES, rs4905794 was associated with echocardiographic left ventricular mass (β = - 7.6 g/m2, P = 0.02). CONCLUSIONS rs4905794 near BCL11B showed evidence for association with nocturnal BP dipping. It also associated with left ventricular mass in GENRES. Combined with earlier data, our results provide support to the idea that BCL11B could play a role in cardiovascular pathophysiology.

Pathophysiology of essential hypertension: an update.
Saxena, T, Ali, AO, Saxena, M
Expert review of cardiovascular therapy. 2018;(12):879-887
Abstract
Hypertension is caused by increased cardiac output and/or increased peripheral resistance. Areas covered: The various mechanisms affecting cardiac output/peripheral resistance involved in the development of essential hypertension are covered. These include genetics; sympathetic nervous system overactivity; renal mechanisms: excess sodium intake and pressure natriuresis; vascular mechanisms: endothelial cell dysfunction and the nitric oxide pathway; hormonal mechanisms: the renin-angiotensin-aldosterone system (RAAS); obesity, obstructive sleep apnea (OSA); insulin resistance and metabolic syndrome; uric acid; vitamin D; gender differences; racial, ethnic, and environmental factors; increased left ventricular ejection force and hypertension and its association with increased basal sympathetic activity - cortical connections. Expert commentary: Maximum association of hypertension is found with sympathetic overactivity which is directly or indirectly involved in different mechanisms of hypertension including RAAS, OSA, obesity, etc.. It is not overt sympathetic activity but disturbed basal sympathetic tone. Basal sympathetic tone arises from hypothalamus; possibly affected by cortical influences. Therefore, hypertension is not merely a disease of circulatory system alone. Its pathogenesis involves alteration in ANS (autonomic nervous system) and likely in cortical-hypothalamic connections. Assessment of ANS and cortical-hypothalamic connections may be required for better understanding of hypertension.

Abstract
Metabolic syndrome (MetS) is associated with diabetes mellitus and cardiovascular diseases. Our previous study indicated that people with MetS showed a decrease in waist circumference and a decreasing trend in blood pressure after 1-year yoga. This study investigated the effect of yoga on MetS people with high-normal blood pressure by exploring modulations in proinflammatory adipokines (leptin, chemerin, visfatin, and plasminogen activator inhibitor-1 or PAI-1) and an anti-inflammatory adipokine (adiponectin). A total of 97 Hong Kong Chinese individuals aged 57.6 ± 9.1 years with MetS and high-normal blood pressure were randomly assigned to control (n = 45) and yoga groups (n = 52). Participants in the control group were not given any intervention but were contacted monthly to monitor their health status. Participants in the yoga group underwent a yoga training program with three 1-hour yoga sessions weekly for 1 year. The participants' sera were harvested and assessed for adipokines. Generalized estimating equation (GEE) was used to examine the interaction effect between 1-year time (pre vs post), and intervention (control vs yoga). GEE analyses revealed significant interaction effects between 1-year time and yoga intervention for the decreases in leptin and chemerin and the increase in adiponectin concentration in the sera examined. These results demonstrated that 1-year yoga training decreased proinflammatory adipokines and increased anti-inflammatory adipokine in adults with MetS and high-normal blood pressure. These findings support the beneficial role of yoga in managing MetS by favorably modulating adipokines.

Abstract
The purpose of this study is to determine an appropriate age threshold at which to recommend the evaluation of moderate and severe periodontitis among Korean adults.This study involved a cross-sectional analysis using data from the Korean National Health and Nutrition Examination Survey from 2012 to 2014. Incidence rates of periodontitis with the 95% confidence interval (CI) were evaluated. The predictive accuracy of age for periodontitis was determined by calculating the area under curve (AUC) on the basis of the receiver operating characteristic (ROC) curve.The cutoff value of age was 43 years in men having periodontitis with an AUC of 0.70 with 95% CI of 0.69 to 0.72. The AUC was 0.72 (95% CI: 0.70-0.73), and the cutoff value of age (49 years) was identified for the moderate periodontitis in women. The cutoff values for age with AUCs and 95% CI for individuals with periodontitis were 46 years (0.72 [0.71-0.73]), 43 years (0.73 [0.72, 0.74]), 45 years (0.71 [0.70,0.72]), 43 years (0.73 [0.72, 0.74]), and 45 years (0.74 [0.72, 0.75]) for no obesity, no abdominal obesity, no diabetes mellitus, no hypertension, and no metabolic syndrome groups, respectively.This study proposed the guideline for the appropriate age threshold at which to recommend the evaluation of moderate and severe periodontitis for the general population and additionally added the guideline for the individuals without systemic disease including diabetes mellitus, hypertension, metabolic syndrome, and obesity. This study suggests that the participants with certain age may be recommended for the regular periodontal evaluation.

Experimental and clinical endocrinology & diabetes : official journal, German Society of Endocrinology [and] German Diabetes Association. 2017;(3):176-182
Abstract
Lipid accumulation product (LAP) is an index used for evaluating lipid overaccumulation in adults. Our study aimed at assessing associations between LAP and metabolic syndrome (MetS) and its components, age-related testosterone deficiency syndrome (TDS), low-density cholesterol (LDL), as well as HOMA-IR (insulin resistance ratio), insulin level in non-diabetics and total testosterone (TT), estradiol E2, dehydroepiandrosterone sulphate (DHEAs) and sex hormone-binding globulin (SHBG) in aging men.313 men aged 50-75 were surveyed with regard to the prevalence of diabetes (T2DM) and hypertension (HT). Anthropometric measurements, including waist circumference and arterial pressure, were performed. We also determined the levels of fasting plasma glucose (FPG), total cholesterol (TC), high-density cholesterol (HDL), low-density cholesterol (LDL), triglyceride (TG), insulin, TT, SHBG, DHEAs, and E2.Patients with diagnosed MetS, T2DM, HT, obesity, overweight and TDS had a significantly higher LAP compared to those without these conditions. LAP was significantly positively correlated with serum TC, FPG, insulin, DHEAs, as well as APB-systolic concentration, and negatively correlated with HDL, TT, and SHBG.LAP may then be used as a simple and inexpensive biomarker of metabolic disorders, and in risk assessment related to testosterone deficiency in aging men.
