Prevalence of Pre-Hypertension/Hypertension and Its Associated Factors Among Adults in the Wolaita Zone of Southern Ethiopia: A Cross-Sectional Study.

Preventing the development of high blood pressure and resulting complication requires estimating the prevalence of prehypertension/hypertension and identifying associated risk factors. Information about pre-hypertension/hypertension in Ethiopia, especially in the southern region, is scarce, and limited knowledge exists regarding the prevalence and risk factors associated with pre-hypertension/hypertension. Objective of this study was to assess prevalence of pre-hypertension/hypertension and its associated factors among adults in Wolaita Zone of Southern Ethiopia, 2023. This cross-sectional study was conducted among adults attending outpatient departments in governmental hospitals in South Ethiopia in 2023. Face-to-face interviews were used to gather information on sociodemographic data, dietary and behavioral patterns, and medical history. Digital weighing scales, Stadiometers, and digital sphygmomanometers were used to measure height, blood pressure, and weight, respectively. Epi-Data version 3.1 was used to enter the data before exporting it to SPSS version 25 for analysis. To find factors associated with prehypertension/hypertension, binary logistic regressions were conducted and odds ratios with 95% confidence intervals were computed. The overall prevalence of prehypertension/hypertension was 42.8% (95% confidence interval: 39.56, 49.47). Factors associated with prehypertension/hypertension in this study were older age, male gender, obesity, diabetes mellitus comorbidity, alcohol drinking, and family history of hypertension. Lifestyle modification is demanded for pre-hypertensive/hypertensive patients to prevent progression to severe complications, including premature death and permanent disabilities.

[Impact of Anthropometric Indices of Obesity on the Risk of Incident Hypertension in Adults with Prehypertension: A Secondary Analysis of a Cohort Study].

PURPOSE: This study aimed to investigate the impact of anthropometric indices of obesity (body mass index [BMI], waist circumference, waist hip ratio, and body fat percentage) on the incidence of hypertension in adults with prehypertension. METHODS: A longitudinal study design using secondary data form the Korean Genome and Epidemiology Study was employed. The study included 1,838 adults with prehypertension tracked every two years from 2001 to 2018. Statistical analyses, including frequency assessments, number of cases per 1,000 person-years, log-rank tests, Kaplan-Meier curves, and Cox's proportional hazards regression, were conducted using SPSS version 25. RESULTS: Over the observation period (15,783.6 person-years), 1,136 individuals developed hypertension. The incidence of hypertension was significantly higher in the obesity groups defined by BMI (hazard ratio [HR] = 1.33), waist circumference (HR = 1.34), waist hip ratio (HR = 1.29), and body fat percentage (HR = 1.31) compared to the non-obese group. These findings indicate an increased risk of hypertension associated with obesity as measured by these indices. CONCLUSION: The study underscores the importance of avoiding obesity to prevent hypertension in individuals with prehypertension. Specifically, BMI, waist circumference, waist hip circumference, and body fat percentage were identified as significant risk factors for hypertension. The results suggest the need for individualized weight control interventions, emphasizing the role of health professionals in addressing the heightened hypertension risk in this population.

[Mediating effects of obesity and metabolic factors in hyperuricemia and prehypertension].

Objective: To assess the mediating effects of obesity and metabolic factors in the relationship between hyperuricemia (HUA) and prehypertension. Methods: A total of 9 399 individuals were selected using a multistage stratified whole-group random sampling method from 90 villages (neighborhood committees) in 30 towns (streets) of 5 districts (counties) in Fuzhou. A total of 4 754 study subjects were included. A linear regression model was used to analyze the association of HUA with obesity and metabolic factors. Single-factor and multi-factor logistic regression models were used to analyze the association of HUA, obesity, and metabolic factors with prehypertension. Mediating effects models were used to analyze the mediating effects of obesity and metabolic factors on the association between HUA and prehypertension. Results: After adjusting for confounders, the association between HUA and cholesterol, triglycerides, HDL-C, LDL-C, BMI, waist circumference, creatinine, and urea nitrogen were significantly correlated (P<0.001). HUA, waist circumference, BMI, and triglycerides were significantly associated with prehypertension (P<0.001). Waist circumference, BMI, and triglycerides mediated the relationship between HUA and prehypertension, with OR (95%CI) of 1.018 (1.007-1.027), 1.010 (1.002-1.018), and 1.010 (1.003-1.017) (P<0.001), with mediating proportions of 7.76%, 4.31%, and 4.31% respectively. No mediating effect of cholesterol, HDL-C, LDL-C, creatinine, and urea nitrogen was found on the relationship (P>0.05). Conclusions: Waist circumference, BMI, and triglycerides all had mediating effects in the association between HUA and prehypertension. For the general population, weight control, waist circumference, and a high-fat diet should be used to reduce the occurrence of prehypertension.

Prevalence and risk factors of pre-hypertension and high blood pressure among adolescents in Cameroonian schools.

Blood pressure (BP) is the main driver of mortality with 12.8% of all deaths worldwide. Adolescents are not spared, precisely in Cameroon where they constitute more than half of its population. The objective of our work was to describe the prevalence and risk factors of pre-hypertension and high blood pressure (HBP) among adolescents in Cameroonian schools. Descriptive study over 5 months; from January to May 2019. The study population consisted of students from private and public schools in the city of Douala. Sociodemographic, anthropometric, and personal background data were collected. Physical activity (PA) was assessed using the short International Physical Activity Questionnaire (IPAQ). Multivariate logistic regression was used to determine factors associated with pre-hypertension and HBP. Differences were considered significant for p < .05. We recruited 771 students with an average age of 16 ± 1 years with female predominance (51.4%). The prevalences of pre-hypertension and HBP were 6.6% and 3%, respectively. Overweight/obesity (OR = 4.6; p < .0001), hyperglycemia [(OR = 4.06; p = .001)] physical inactivity (OR = 1.85; p = .019), and public institutions (OR = 1.87; p = .02) were associated with pre-hypertension. Similarly, overweight/obesity (OR = 2.99; p = .022), hyperglycemia (OR = 14.05; p < .0001), and physical inactivity (OR = 8.58; p < .0001) were correlated with HBP. Pre-hypertension and HBP are high in Cameroonian school adolescents and their risk factors are overweight/obesity, hyperglycemia, and physical inactivity.

Prognostic Implication of Pulmonary Arterial Pressure in Surgical Repair of Predominantly Congenital Mitral Valve Regurgitation-Based Intracardiac Abnormalities.

INTRODUCTION: Knowledge is limited regarding the significance of pulmonary arterial pressure (PAP) in predominantly congenital mitral valve regurgitation (MR)-based intracardiac abnormalities. METHODS: From a prospective cohort, we included 200 patients with congenital MR regardless of other associated intracardiac abnormalities (mean age 60.4 months, 67% female, systolic PAP (sPAP) 54.2 mm Hg) surgically repaired in 2012-2019 and followed up to 2020 (median 30.0 months). Significant pulmonary hypertension (PH) was defined as sPAP >50 mm Hg at rest or mean PAP >25 mm Hg on right heart catheterization. By perioperative sPAP changes, patients were stratified as group I (pre-normotension to post-normotension), group II (pre-hypertension to post-normotension), or group III (pre-hypertension to post-hypertension). Primary outcomes were the recurrence of MR (defined as the regurgitation grade of moderate or greater) and the progression of MR (defined as any increase in the magnitude of regurgitation grade after surgery). Cox proportional hazard and Kaplan-Meier curve were performed. RESULTS: There was no association between preoperative PH and the recurrent MR (adjusted hazard ratios [aHR]: 1.146 [95% CI: 0.453-2.899]) and progressive MR (aHR: 1.753 [95% CI: 0.807-3.804]), respectively. There were no significant differences among group I, group II, and group III in the recurrent MR but in the progressive MR. A dose dependency was identified for preoperative sPAP with recurrent MR (aHR: 1.050 [95% CI: 1.029-1.071]) and progressive MR risks (aHR: 1.037 [95% CI: 1.019-1.055]), respectively. CONCLUSIONS: Preoperative higher sPAP is associated with worse outcomes, warranting heightened attention to the identification of perioperative sPAP.

The policy implemented by the government and the protection effect of PM2.5 decreasing on blood pressure in adolescents: From a quasi-experimental study.

Background: High particulate matter with an aerodynamic diameter of 2.5 µm or less (PM2.5) exposure levels posed a great risk to human health, but the protection effects of environmental protection on cardiovascular disease have not been systematically evaluated. This study aims to illustrate the effect of the decreased concentration of PM2.5 on blood pressure level in adolescents after enacting the protection measures of environment from a cohort study. Methods: A quasi-experimental study including 2415 children from the Chongqing Children's Health Cohort, aged 7.32 ± 0.60 years with normal blood pressure at baseline, with 53.94% males, were analysed. Both the generalised linear regression model (GLM) and Poisson regression model were used to calculate the impact of the declining exposure level of PM2.5 on blood pressure and the incidence of prehypertension and hypertension. Results: The annual mean PM2.5 concentration in 2014 and in 2019 were 65.01 ± 6.46 µgmes per cubic metre (µg / m3), 42.08 ± 2.04 µg / m3 respectively, and the decreased PM2.5 concentration between 2014 and 2019 was 22.92 ± 4.51 µg / m3. The effect of decreased PM2.5 concentration by 1µg / m3 on systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and the difference of blood pressure (BP) indexes between 2014 and 2019 were all significant (P < 0.001). The absolute differences of SBP (-3.598 mmHg; 95% confidence interval (CI) = -4.47,-2.72 mm Hg), DBP (-2.052 mmHg; 95% CI = -2.80,-1.31 mm Hg) and MAP (-2.568 mmHg; 95% CI = -3.27,-1.87 mm Hg) in the group with a decreased level of ≥25.56 µg / m3 were more significant than those in a decreased concentration of PM2.5 for <25.56 µg / m3 (P < 0.001). And the incidence of prehypertension and hypertension for three occasions blood pressure diagnose was 2.21% (95% CI = 1.37%-3.05%, P = 0.001) in children with PM2.5 decreased level ≤25.56 µg / m3 (50%), which was significant higher than its' counterparts 0.89% (95% CI = 0.37%-1.42%, P = 0.001). Conclusions: Our study found the etiological relationship between the declining PM2.5 concentration and the BP values and the incidence of prehypertension and hypertension in children and adolescents, suggesting continuous environmental protection measures in China have achieved remarkable health benefits.

Severity of non-alcoholic fatty liver disease is a risk factor for developing hypertension from prehypertension.

BACKGROUND: There is little published evidence about the role of non-alcoholic fatty liver disease (NAFLD) in the progression from prehypertension to hypertension. This study was conducted to investigate the association of NAFLD and its severity with the risk of hypertension developing from prehypertension. METHODS: The study cohort comprised 25,433 participants from the Kailuan study with prehypertension at baseline; those with excessive alcohol consumption and other liver diseases were excluded. NAFLD was diagnosed by ultrasonography and stratified as mild, moderate, or severe. Univariable and multivariable Cox proportional hazard regression was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) of incident hypertension according to the presence and 3 categories of severity of NAFLD. RESULTS: During a median of 12.6 years of follow-up, 10,638 participants progressed to hypertension from prehypertension. After adjusting for multiple risk factors, patients with prehypertension and NAFLD had a 15% higher risk of incident hypertension than those without NAFLD (HR = 1.15, 95% CI 1.10-1.21). Moreover, the severity of NAFLD was associated with the incidence of hypertension, which was higher in patients with more severe NAFLD (HR = 1.15 [95% CI 1.10-1.21] in the mild NAFLD group; HR = 1.15 [95% CI 1.07-1.24] in the moderate NAFLD group; and HR = 1.20 [95% CI 1.03-1.41] in the severe NAFLD group). Subgroup analysis indicated that age and baseline systolic blood pressure may modify this association. CONCLUSIONS: NAFLD is an independent risk factor for hypertension in patients with prehypertension. The risk of incident hypertension increases with the severity of NAFLD.

Short- to long-term blood pressure variability: Current evidence and new evaluations.

Increased blood pressure (BP) variability and the BP surge have been reported to be associated with increased cardiovascular risk independently of BP levels and can also be a trigger of cardiovascular events. There are multiple types of BP variation: beat-to-beat variations related to breathing and the autonomic nervous system, diurnal BP variation and nocturnal dipping related to sleep and physical activity over a 24-hr period, day-to-day BP variability with anomalous readings within a several-day period, visit-to-visit BP variability between outpatient visits, and seasonal variations. BP variability is also associated with the progression to hypertension from prehypertension and the progression of chronic kidney disease and cognitive impairments. Our research group proposed the "resonance hypothesis of blood pressure surge" as a new etiological hypothesis of BP variability and surges; i.e., the concept that when the time phases of surges and hypertension-inducing environmental influences coincide, resonance occurs and is amplified into a larger "dynamic surge" that triggers the onset of cardiovascular disease. New devices to assess BP variability as well as new therapeutic interventions to reduce BP variability are being developed. Although there are still issues to be addressed (including measurement accuracy), cuffless devices and information and communication technology (ICT)-based BP monitoring devices have been developed and validated. These new devices will be useful for the individualized optimal management of BP. However, evidence regarding the usefulness of therapeutic interventions to control BP variability is still lacking.

Hypertension and atrial fibrillation.

Hypertension is the most prevalent cardiovascular risk factor underlying atrial fibrillation and is present in up to 40% of patients with atrial fibrillation. Furthermore, attributable risk studies have shown that a history of hypertension contributes to up to 24% of incident atrial fibrillation. New data suggest that even early forms of hypertension (prehypertension and aortic stiffness) are associated with an increased risk of atrial fibrillation development. Hypertension and prehypertension are therefore critical mediators for the development of atrial fibrillation. Mechanisms for the association between hypertension and atrial fibrillation include diffuse electro-structural changes to the left atrium, driven by the haemodynamic and neurohormonal influences of hypertension and other, frequently coexisting, cardiovascular risk factors. Management of hypertension in atrial fibrillation should focus not only on blood pressure reduction but also on a comprehensive risk factor modification strategy. Such strategies have been shown to be associated with significant improvements in atrial fibrillation symptom burden as well as improved arrhythmia-free survival and reversal of the progression of atrial fibrillation. These strategies should focus on dietary modifications as well as prescribed exercise programmes involving a multidisciplinary team and patient-centred atrial fibrillation care. Risk factor management, supplemented by antihypertensive medications as needed, provides the optimum strategy for improving outcomes and even reversing the natural progression of atrial fibrillation in patients with hypertension.

Severity of Nonalcoholic Fatty Liver Disease is Associated With Cardiovascular Outcomes in Patients With Prehypertension or Hypertension: A Community-Based Cohort Study.

Background: It is unclear whether more severe non-alcoholic fatty liver disease (NAFLD) combined with prehypertension or hypertension is associated with a higher risk of cardiovascular events (CVEs). To evaluate the relationship between the severity of NAFLD and CVEs among patients with prehypertension or hypertension. Methods: In this prospective community-based Kailuan cohort, participants without cardiovascular disease and alcohol abuse, or other liver diseases were enrolled. NAFLD was diagnosed by abdominal ultrasonography. Prehypertension was defined as systolic blood pressure (BP) of 120-139 mmHg or diastolic BP of 80-89 mmHg. Participants with NAFLD were divided into mild, moderate, and severe subgroups. Follow-up for CVEs including myocardial infarction, hemorrhagic stroke, and ischemic stroke. The Cox proportional hazards model was used to estimate hazard ratios and 95% CIs of CVEs according to the severity of NAFLD and hypertensive statutes. The C-statistic was used to evaluate the efficiency of models. Results: A total of 71926 participants (mean [SD] age, 51.83 [12.72] years, 53794 [74.79%] men, and 18132 [25.21%] women) were enrolled in this study, 6,045 CVEs occurred during a median of 13.02 (0.65) years of follow-up. Compared with participants without NAFLD, the hazard ratios of CVEs for patients with mild, moderate, and severe NAFLD were 1.143 (95% CI 1.071-1.221, P < 0.001), 1.218 (95% CI 1.071-1.221, P < 0.001), and 1.367 (95% CI 1.172-1.595, P < 0.001), respectively. Moreover, participants with prehypertension plus moderate/severe NAFLD and those with hypertension plus moderate/severe NAFLD had 1.558-fold (95% CI 1.293-1.877, P < 0.001) and 2.357-fold (95% CI 2.063-2.691, P < 0.001) higher risks of CVEs, respectively, compared with those with normal BP and no NAFLD. Adding a combination of NAFLD and BP status to the crude Cox model increased the C-statistic by 0.0130 (0.0115-0.0158, P < 0.001). Conclusions: Our findings indicated that the increased cardiovascular risk with elevated BP is largely driven by the coexistence of moderate/severe NAFLD, suggesting that the severity of NAFLD may help further stratify patients with prehypertension and hypertension.

The Association of Dietary Pattern with the Risk of Prehypertension and Hypertension in Jiangsu Province: A Longitudinal Study from 2007 to 2014.

Hypertension is the most common chronic disease and the primary risk factor for cardiovascular diseases. Prehypertension is closely related to a variety of cardiovascular disease risk factors during the development of hypertension. The objective of this study was to explore the relationship between dietary patterns and hypertension in Jiangsu Province. Specifically, we included the participants from 2007 and then followed up in 2014 in the Jiangsu Province of China and collected information from food frequency questionnaires, anthropometric measurements, and disease self-reports. A total of 1762 women and men were included in the final analysis. We extracted four dietary patterns using factor analysis, calculated the pattern-specific factor scores, and divided the scores into quartiles, which increased from Q1 to Q4. Compared with participants in Q1, an increased risk of high diastolic blood pressure was found in Q4 of the snack dietary pattern. Additionally, participants in Q2-Q4 of the frugal dietary pattern were found to have a positive association with abnormal blood pressure. However, the results found in the frugal dietary pattern vanished after adjusting more confounders in Q4 of high systolic blood pressure. We found that some food items were associated with hypertension and prehypertension. The overconsumption of salt and alcohol are risk factors for both prehypertension and hypertension. Added sugar and saturated fatty acids are risk factors for hypertension, which may provide suggestions for the residents in China to change dietary habits to prevent prehypertension and hypertension.

Prevalence of Prehypertension and Associated Cardiovascular Risk Profiles among Adults in Peru: Findings from a Nationwide Population-Based Study.

Prehypertension is a clinical condition that increases the risk of hypertension and cardiovascular disease. In South American countries, prehypertension affects almost one-third of the population. The aim of the present study was to determine the association between prehypertension and the main cardiometabolic risk factors according to the US National Cholesterol Education Program Adult Treatment Panel III by sex in the Peruvian population. A total of 863 participants surveyed were included in the study. A total of 21.1% had prehypertension, 14.4% of whom were female, and 30.5% were male. Women belonging to the age group 50-59 years, having abdominal obesity and being a current smoker, were more likely to have prehypertension, while the likelihood of having prehypertension increased in men with abdominal obesity. Three out of 10 men and one out of 10 women in Peru have prehypertension. In women, being 50 to 59 years of age, having abdominal obesity, and being a current smoker, increased the probability of having prehypertension, whereas, in men, only abdominal obesity was found to be associated with prehypertension. Our findings will allow the development of prevention strategies focused on the appropriate diagnosis of prehypertension and cardiometabolic risk factors according to sex.

Chinese Visceral Adiposity Index Is More Closely Associated With Hypertension and Prehypertension Than Traditional Adiposity Indices in Chinese Population: Results From the REACTION Study.

Purpose: The optimal adiposity index that is strongly associated with hypertension or prehypertension remains inconclusive in Chinese population. This study aimed to investigate the relationship between Chinese visceral adiposity index (CVAI) and hypertension and prehypertension, as well as to compare the discriminative power of CVAI, visceral adiposity index (VAI), body mass index (BMI), waist circumference (WC), waist to height ratio (WHtR), low-density lipoprotein cholesterol (LDL-C), and waist-to-hip ratio (WHR) with hypertension and prehypertension in Chinese general population. Patients and Methods: A total of 34732 participants from REACTION study were recruited. Multiple logistic regression analyses were performed to detect the association between adiposity indices (CVAI, VAI, BMI, WC, WHtR, WHR, LDL-C) and hypertension and prehypertension. Results: Multivariate logistic regression analysis showed that compared with other obesity indices, CVAI remained significantly associated with hypertension and prehypertension (Hypertension: odds ratio (OR) 3.475, 95% confidence interval (CI) 3.158-3.824, p<0.001 in total subjects; OR 2.762, 95% CI 2.369-3.221, p<0.001 in men; OR 3.935, 95% CI 3.465-4.469, p<0.001 in women, Prehypertension: OR 2.747, 95% CI 2.460-3.068, p<0.001 in total subjects; OR 2.605, 95% CI 2.176-3.119, p<0.001 in men; OR 2.854, 95% CI 2.465-3.304, p<0.001 in women).In a stratified analysis, CVAI was significantly associated with hypertension and prehypertension at any level of blood glucose, age or estimated glomerular filtration rate(eGFR). Conclusion: CVAI is significantly associated with hypertension and prehypertension. CVAI shows the superior discriminative ability for hypertension and prehypertension compared with VAI, BMI, WC, WHtR, WHR and LDL-C in Chinese general population.

Association Between METS-IR and Prehypertension or Hypertension Among Normoglycemia Subjects in Japan: A Retrospective Study.

Aim: Our study aimed to investigate the association between the novel non-insulin-based metabolic score for insulin resistance (METS-IR) index and pre-hypertension (HTN) or HTN in normoglycemia Japanese participants. Methods: The NAGALA medical examination program at Murakami Memorial Hospital in Gifu, Japan was found in 1994. 15,453 participants enrolled in this program from 2004 to 2015 was included in this retrospective study to explore the association between the METS-IR index and pre-HTN or HTN. Covariates included serum biomarkers and clinicodemographic characteristics. Logistic regression was applied to explore the association between METS-IR level and pre-HTN or HTN. Results: This study includes a total of 15453 participants. The prevalence rates of pre-HTN and HTN were 28.55% (4412/15453) and 6.23% (962/15453), respectively. Adjusted for confounding factors in the multivariable logistic regression analysis models, when METS-IR was used as a categorical variable, high METS-IR was significantly associated with both pre-HTN (adjusted odds ratio (OR) = 1.95, 95% confidence interval (CI): 1.61-2.36) and HTN (adjusted OR = 2.12, 95% CI: 1.44-3.11). When METS-IR was used as a continuous variable, each 1 unit increase in METS-IR was associated with a 7% increase in the prevalence of pre-HTN (adjusted OR = 1.07, 95% CI: 1.06-1.08) and with a 13% increase in the prevalence of HTN (adjusted OR = 1.13, 95% CI: 1.10-1.16). Stratified analyses indicated a positive correlation between METS-IR and pre-HTN or HTN in normoglycemia subjects with different characteristics. Conclusions: METS-IR levels are significantly associated with pre-HTN or HTN in normoglycemia individuals in Gifu, Japan. METS-IR may be used as a monitoring indicator for the development of HTN primary prevention and management strategies in the future, but it still needs more research to confirm.

Beneficial Impact of Pork Dry-Cured Ham Consumption on Blood Pressure and Cardiometabolic Markers in Individuals with Cardiovascular Risk.

BACKGROUND: Evidence suggests that bioactive peptides reduce hypertension and affect certain metabolic pathways. METHODS: Fifty-four volunteers with stage 1 prehypertension and/or hypercholesterolemia and/or basal glucose >100 mg/dL were recruited and randomized to pork dry-cured ham (n = 35) or cooked ham (placebo group; n = 19) for 28 days. After a wash-out period, meat products were changed for 28 additional days. Bioactive peptides composition and enzyme inhibitory activities of both products were characterized. Treatment comparisons for the main effects were made using a two (treatment) × two (times) repeated measures minus the effect of cooked ham (placebo). RESULTS: 24 h mean systolic and diastolic pressures decreased up to 2.4 mmHg in the dry-cured ham period (treatment effect, p = 0.0382 y p = 0.0233, respectively) as well as the number of systolic pressure measures > 135 mmHg (treatment effect, p = 0.0070). Total cholesterol levels also decreased significantly after dry-cured ham intake (p = 0.049). No significant differences were observed between the two treatments for basal glucose, HOMA-IR index and insulin levels (p > 0.05). However, a significant rise of ghrelin levels was observed (treatment effect, p = 0.0350), while leptin plasma values slightly decreased (treatment effect, p = 0.0628). CONCLUSIONS: This study suggested the beneficial effects of regular dry-cured ham consumption on the improvement of systolic/diastolic blood pressures and facilitated the maintenance of metabolic pathways, which may be beneficial in the primary prevention of cardiovascular disease.

The relationship of interleukin-6 and C-reactive protein with left ventricular geometry and function in patients with obstructive sleep apnea syndrome and pre-hypertension.

OBJECTIVE: To assess the relationship of interleukin-6 (IL-6) and C-reactive protein (CRP) levels with left ventricular geometry (LVG) and function in patients with obstructive sleep apnea syndrome (OSAS) and pre-hypertension. METHODS: A total of 458 patients were assigned into four groups: normal geometry (NG), concentric remodeling (CR), eccentric hypertrophy (EH), and concentric hypertrophy (CH). Pearson correlation and multivariate logistic regression analyses were used to determine the correlation between IL-6, CRP, and clinical, polysomnographic, and biochemical parameters with LVG and function. RESULTS: IL-6 and CRP levels were higher in the EH and CH groups than those in the NG and CR groups. The results of the Pearson correlation analysis showed that IL-6 level was positively correlated with the E/e' ratio and peak systolic pulmonary venous reverse velocity (PVa) duration time (PVaD), while negatively correlated with the E/A ratio, s', and left ventricular ejection fraction (LVEF). CRP level was positively correlated with A-wave duration time (AD), peak systolic pulmonary venous flow velocity (PVs), PVa and PVaD, while negatively correlated with the E/A ratio. The results of the multivariate logistic regression analysis revealed that IL-6 and CRP levels were correlated with EH (ß = 1.213, odds ratio [OR] = 3.363, p < 0.001; ß = 1.258, OR = 3.518, p < 0.001) and CH (ß = .938, OR = 2.555, p = 0.008; ß = 1.239, OR = 3.454, p < 0.001). CONCLUSION: IL-6 and CRP levels are associated with LVG and function, suggesting that IL-6 and CRP levels are involved in OSAS and pre-hypertension, leading to abnormal left ventricular structure and function.

Gut mycobiome dysbiosis contributes to the development of hypertension and its response to immunoglobulin light chains.

Objectives: Human gut microbiome has gained great attention for its proposed roles in the development of hypertension. The fungal microbiome in the human gut (i.e. the mycobiome) is beginning to gain recognition as a fundamental part of our microbiome. However, the existing knowledge of human mycobiome has never revealed the association between gut mycobiome and hypertension. It is known that inflammation and immunity contribute to human hypertension. Here, we sought to investigate whether gut mycobiome could predict the development of hypertension and its association with immunoglobulin light chains. Methods and materials: Participants were classified into three cohorts: prehypertension (pre-HTN), hypertension (HTN), and normal-tension (NT) based on their blood pressure. Fresh samples were collected, and the ITS transcribed spacer ribosomal RNA gene sequence was performed. An immunoturbidimetric test was used to examine the serum levels of immunological light chains. Results: Subjects in both of the states of pre-HTN and HTN had different fungal microbiome community compared to the NT group (FDR<0.05). Slightly higher levels of fungal richness and diversity were observed in the groups of pre-HTN and HTN. The relative abundance of Malassezia increased in the HTN group compared to that in the NT group, and the relative abundance of Mortierella enriched in the NT group. For the pre-HTN group, the relative abundance of Malassezia was positively associated with serum the concentration of light chain (LC) κ (r=0.510, P=0.044); for the HTN group, the relative abundance of Mortierella was positively associated with the serum concentration of LC κ (P<0.05), the relative abundance of Malassezia was positively associated with both the serum concentrations of LC κ and LC λ (r>0.30, P<0.05). Conclusions: Our present study demonstrated that gut fungal dysbiosis occurred in the state of prehypertension, and fungal dysbiosis can predict the dysregulation of serum light chains in hypertension patients. Further study on modulating gut fungal community should be focused on balancing the immunological features in hypertension.

Prevalence of CVD risk factors among some tribal and nontribal populations of Jharkhand - A comparative survey.

BACKGROUND: World especially India had been witnessing a sharp increase of death and disability due to cardiovascular disease (CVD). Prevention, cure and management of cardiovascular diseases (CVD) necessitate true picture of the spread of CVD risk factors throughout the country. Among few surveys in India, very little reports were from state Jharkhand. This study aimed to report the status of CVD risk factors among tribal and nontribal population of Jharkhand. METHODS: Comparative study was conducted on rural tribals and urban nontribals with no apparent CVD related symptoms. Informed consents, filled up CVD risk questionnaire were collected. Anthropometric and behavioral data with measured Blood pressure (BP), blood sugar and body mass index (BMI) were analyzed by multivariate logistic regression to find out the association of inappropriate features related to CVD, if any with age, gender and ethnicity. RESULTS: Almost 2 fold more susceptibility to develop hypertension, pre-hypertension and obesity was found in nontribals over 8.0%, 15.6% and 22.1% of respective affected tribals. This trend increased up to 3 fold in > 40 years age group. This >40 when compared with < 40 years age group nearly 16 fold and 11 fold significantly increased hypertension risk was reported in nontribals and tribals respectively We report 14.8% diabetic in tribals, highest so far in India. CONCLUSION: With age above 40 years, susceptibility to different CVD risk factors like hypertension, pre-hypertension, obesity, high MAP reported to increase severely in urban nontribals than rural tribals.
