Gene encoding flavin-containing monooxygenase 3 (FMO3), a microsomal antioxidant defense enzyme, has been suggested to contribute to essential hypertension (EH). The present study was designed to investigate whether common functional polymorphism E158K (rs2266782) of theFMO3gene is associated with EH susceptibility in a Russian population. A total of 2 995 unrelated subjects from Kursk (1 362 EH patients and 843 healthy controls) and Belgorod (357 EH patients and 422 population controls) regions of Central Russia were recruited for this study. DNA samples from all study participants were genotyped for theFMO3gene polymorphism through PCR followed by RFLP analysis. We found that the polymorphism E158K is associated with increased risk of essential hypertension in both discovery population from Kursk region (OR 1.36 95% CI 1.09–1.69,P=0.01) and replication population from Belgorod region (OR 1.54 95% CI 1.07–1.89,P=0.02) after adjustment for gender and age using logistic regression analysis. Further analysis showed that the increased hypertension risk in carriers of genotype 158KK gene occurred in cigarette smokers, whereas nonsmoker carriers of this genotype did not show the disease risk. This is the first study reporting the association of theFMO3gene polymorphism and the risk of essential hypertension.

Background Individual blood cell count abnormalities have been associated with cardiovascular disease and increased mortality. In this study, we defined a “cytopenia phenotype,” reflecting bone marrow hypoproliferation, to determine if peripheral blood cytopenia is associated with increased cardiovascular disease and mortality risk. Methods and Results Study participants were derived from a biracial observational cohort study, REGARDS (Reasons for Geographic and Racial Differences in Stroke), that enrolled 30 239 Black and White participants aged ≥45 years between 2003 and 2007. Median follow up was ≈9 years. The current study included 19 864 participants from REGARDS study (37.9% men, 40% Black participants) who have complete blood count available at study enrollment. We defined a cytopenia phenotype based on age‐, sex‐, and race‐adjusted lowest fifth percentile of blood counts. Multivariable Cox proportional hazards models estimated the hazard ratios (HR) and 95% CI of cytopenia for mortality and incident cardiovascular disease in adjusted models. Mean age of the study participants was 64 years (SD:9.7). The prevalence of cytopenia was 1.9% (n=378). Cytopenia was associated with increased risk of all‐cause mortality (HR, 1.73; 95% CI, 1.34–2.22) and cardiovascular disease mortality (HR, 1.56; 95% CI, 1.11–2.29). Cytopenia was associated with stroke risk in Black but not White participants (HR, 1.96 versus 0.86; P ‐interaction for race=0.08) and was not associated with coronary heart disease risk. Conclusions We defined a cytopenia phenotype with clinical implications for mortality and stroke risk in a large biracial and geographically diverse population. Whether generated through somatic mutations or decreased organ function, cytopenia was associated with mortality risk and was a race‐specific risk factor for stroke.

Abstract BackgroundIndividuals with type 2diabetes mellitus (T2DM) commonly present with gastro intestinal symptoms. Exact pathophysiology behind these symptoms is not elucidated. Previous studies reported the role of adrenoceptors on gut motility. However, no study has been conducted to observe whether adrenergic beta receptor (ADRB) 2 and 3 gene polymorphism could influence the gut motility in T2DM. Materials and Methods:Three hundred T2DM patients and 200 age and sex matched healthy controls were enrolled for this study. Participants were subjected to lactulose hydrogen breath test for estimation of orocecal transit time (OCTT). To carry out polymorphism study, buffy coat of EDTA blood was used for DNA isolation followed by polymerase chain reaction and restriction fragment length polymorphism. Results:In this study, the frequency of C allele as well as CC genotype of ADRB3 gene polymorphism and A allele as well as AA genotype of ADRB2 gene polymorphism were significantly higher in patients than controls and was associated with increased risk for T2DM. On comparison of gut motility, OCTT was found to be significantly prolonged (p<0.01) in individuals with CC genotype compared to TT or CT genotype in ADRB3 polymorphism and AA genotype, compared to AG and GG genotype in case of ADRB2 polymorphism. Combined effect of both adrenoceptors on gut motility revealed that individuals having AG or AA genotype in combination with other genotypes had significantly prolonged OCTT. Conclusion:It could be concluded that beta adrenoceptor gene polymorphism has significant role on regulation of gut motility in T2DM.

This research paper deals with the Family Environment and its Correlation with Anxiety and Depression level among persons with Heart Disease. There had been a number of researches that investigated that ischemic heart disease patients who suffer significant anxiety have close to a 5-fold increased risk of experiencing frequent angina and those with depression have more than a 3-fold increased risk for these episodes. This observed link between psychiatric symptoms and angina underlines the importance of treating anxiety and depression in cardiac patients, according to study co author Dr Mark D Sullivan (University of Washington School of Medicine, Seattle). To gather the needed data, Hamilton Anxiety Scale and Becks Depression Inventory were used. As stated from literatures, for people with heart dysfunction, depression and anxiety can increase the risk of an adverse cardiac event such as a heart attack or blood clots. For people who do not have heart disease, depression and anxiety can also increase the risk of a heart attack and development of coronary artery disease. Researchers have also emphasized on the role of family psychosocial environment and its positive association with the Coronary Heart Disease risk.

Endometriosis is a disease very common nowadays affecting 1-2% of the female population, by estrogen-dependent mechanism. The identification of mutations in the gene encoding for the FSH receptor (FSHR) has been reported since 1995. Physiology teaches us that follicle-stimulating hormone (FSH) is a hormone that is vital in the steroidogenesis regulation mechanisms, while FSH receptor (FSHR) activation helps to promote folliculogenesis and estrogensynthesis. Therefore, studies to show if there are any correlations between endometriosis and FSHR are acquired. Genotyping of FSHR gene polymorphisms were performed using PCR - Restriction Fragment Length Polymorphism (PCR-RFLP) analysis. We analysed a total of 78 patients, 44 infertile patients with endometriosis and 34 controls (non-infertile, pregnant patients). The endometriosis group included women with diagnosis of endo-metriosis confirmed by laparoscopy and /or laparotomy and histological evidence of disease with the endometriosis staging according to American Society for Reproductive Medicine (ASRM). Corroborated with the severity of endometriosis, A919G and A2039G tests found that 71.4% of the M (GG) results were associated with primary infertility, not statistically significant (p=0.994) and 42.9% of the total M results had moderate or severe forms of endometriosis (p = 0.185). The genetic involvement in different pathologies such as endometriosis, has yet to be understood, but knowing more about its mechanism, will help physician target the disease at a more profound level.

Basing on Multifactor Dimensionality Reduction method we showed that polymorphic variants p.Q399R (rs25487, XRCC1) and p.P72R (rs1042522, TP53) correlated with increased risk of breast cancer for women from the Kyrgyz Republic and the Republic of Belarus. Cohort for investigation included patients with clinically verified breast cancer: 117 women from the Kyrgyz Republic (nationality - Kyrgyz) and 169 - of the Republic of Belarus (nationality - Belarusians). Group for comparison included (healthy patients without history of cancer pathology at the time of blood sampling) 102 patients from the Kyrgyz Republic, 185 - from the Republic of Belarus. Respectively genotyping of polymorphic variants p.Q399R (rs25487, XRCC1) and p.P72R (rs1042522, TP53) was done by PCR-RFLP. Analysis of the intergenic interactions conducted with MDR 3.0.2 software. Both ethnic groups showed an increase of breast cancer risk in the presence of alleles for SNPs Gln p.Q399R (XRCC1) in the heterozygous state: for the group “Kyrgyz” - OR=2,78 (95% CI=[1,60-4,82]), p=0,001; for the group “Belarusians” - OR=1,85 (95% СІ=[1Д1-2,82], p=0,004. Carriers with combination of alleles Gln (p.Q399R, XRCC1) and Pro (p.P72R, TP53) showed statistically significance increases of breast cancer risk as for patients from the Kyrgyz Republic (OR=2,89, 95% CI=[1,33-6,31]), so as for patients from the Republic of Belarus (OR=3,01, 95% CI=[0,79-11,56]).

Meta Analyses

: Sleep is essential to and an integral part of life and when lacking or disrupted, a multitude of mental and physical pathologies ensue, including cardiovascular (CV) disease, which increases health care costs. Several prospective studies and meta-analyses show that insomnia, short (<7h) or long (>9h) sleep and other sleep disorders are associated with an increased risk of hypertension, metabolic syndrome, myocardial infarction, heart failure, arrhythmias, CV disease risk and/or mortality. The mechanisms by which insomnia and other sleep disorders lead to increased CV risk may encompass inflammatory, immunological, neuro-autonomic, endocrinological, genetic and microbiome perturbations. Guidelines are emerging that recommend a target of >7 h of sleep for all adults >18 years for optimal CV health. Treatment of sleep disorders includes cognitive-behavioral therapy considered the mainstay of non-pharmacologic management of chronic insomnia, and drug treatment with benzodiazepine receptor agonists binding to gamma aminobutyric acid type A (benzodiazepine and non-benzodiazepine agents) and some antidepressants. However, observational studies and meta-analyses indicate an increased mortality risk of anxiolytics and hypnotics, although bias may be involved due to confounding and high heterogeneity in these studies. Nevertheless, it seems that the risk incurred by the non-benzodiazepine hypnotic agents (Z drugs) may be relatively less than the risk of anxiolytics, with evidence indicating that at least one of these agents, zolpidem, may even confer a lower risk of mortality in adjusted models. All these issues are herein reviewed.

AbstractObjectivesTo compare the long-term effects of antenatal betamethasone (ANS, ≤16 mg, =24 mg and >24 mg) in twins on infant and childhood growth.MethodsA retrospective cohort follow up study among 198 twins after ANS including three time points: U1 first neonatal examination after birth and in the neonatal period; U7 examination from the 21st to the 24th month of life and U9 examination from the 60th to the 64th month of life using data from copies of the children’s examination booklets. Inclusion criteria are twin pregnancies with preterm labor, cervical shortening, preterm premature rupture of membranes, or vaginal bleeding, and exposure to ANS between 23+5 and 33+6 weeks. Outcome measures are dosage-dependent and sex-specific effects of ANS on growth (body weight, body length, head circumference, body mass index and ponderal index) up to 5.3 years.ResultsOverall, 99 live-born twin pairs were included. Negative effects of ANS on fetal growth persisted beyond birth, altered infant and childhood growth, independent of possible confounding factors. Overall weight percentile significantly decreased between infancy and early childhood by 18.8%. Birth weight percentiles significantly changed in a dose dependent and sex specific manner, most obviously in female-female and mixed pairs. The ponderal index significantly decreased up to 42.9%, BMI index increased by up to 33.8%.ConclusionsANS results in long-term alterations in infant and childhood growth. Changes between infancy and early childhood in ponderal mass index and BMI, independent of dose or twin pair structure, might indicate an ANS associated increased risk for later life disease.SynopsisFirst-time report on long-term ANS administration growth effects in twin pregnancies, showing persisting alterations beyond birth in infant and childhood growth up to 5.3 years as potential indicator of later life disease risk.

Abstract Background Understanding the relationship between breastfeeding (BF) and metabolic syndrome (Mets) is important for maternal long-term health benefits and disease prevention. This study aimed to examine the association between BF and Mets and its components among postmenopausal parous Korean women. Methods This cross-sectional study on 10,356 Korean women used nationally representative data from the KNHANES from 2010 to 2016. Anthropometric, laboratory data and manual BP were measured. A multivariate logistic regression analysis was conducted to examine the association of BF with Mets and its components after adjusting for potential confounding variables. A p-value < 0.05 was to be considered statistically significant. Results Mets was present in 42% of the study participants. The BF group had low household income and education level. The prevalence of Mets in the BF group was higher than that in the non-BF group (42.69% vs. 34.76%, p <  0.001). BF was associated with increased risk of Mets (odds ratio [OR]: 1.4, 95% confidence interval [CI]: 1.18–1.65, p <  0.001). The BF group was at higher risks for diabetes (OR: 1.5, 95%CI: 1.14–1.98), hypertension (OR: 1.32, 95%CI: 1.03–1.68), hypertriglyceridemia (OR: 1.42, 95%CI: 1.02–1.99) and low high-density lipoprotein cholesterol (OR: 1.32, 95%CI: 1.06–1.65). Conclusion In this study, BF did not affect decreasing the prevalence of Mets and its components.
