Hypertension may associate with cerebral small vessel disease and infarcts through the pathway of intracranial atherosclerosis

Hypertension, a major modifiable risk factor for cardiovascular diseases, is linked to late-life neurocognitive disorders such as vascular dementia and Alzheimer's disease (AD). This study explores the associations between hypertension, intracranial atherosclerotic disease (ICAD), cerebral small vessel disease (cSVD), and Alzheimer's disease neuropathologic change (ADNC) in a large community-based autopsy study.This cross-sectional study used data from the Biobank for Aging Studies of the University of São Paulo Medical School. Sociodemographic and clinical information was gathered from a reliable next-of-kin informant. Neurofibrillary tangles, neuritic plaques, lacunar infarcts, hyaline arteriolosclerosis, and cerebral amyloid angiopathy were evaluated. Causal mediation analyses with natural effect models were performed to examine indirect associations of hypertension with cerebrovascular pathologies and ADNC through morphometric measurements of intracranial artery lumen obstruction.Hypertensive participants (n = 354) presented a higher rate of stenosed arteries (obstruction ≥ 50%), critically stenosed arteries (obstruction ≥ 70%), and more severe ICAD, shown by higher maximum and mean obstruction indexes compared to nonhypertensive participants (n = 166). These measurements of atherosclerosis were associated with neurofibrillary tangles and cSVD lesions. Hypertension was indirectly associated with hyaline arteriolosclerosis and lacunar infarcts through the pathway of ICAD. Presenting hypertension indirectly increased the odds of displaying hyaline arteriolosclerosis by 26% (95% CI: 1.08, 1.45, p = 0.002) and lacunar infarcts by 17% (95% CI: 1.01, 1.35, p = 0.029). Cognitive and APOE ε4 carrier status did not alter the investigated associations. In this community sample, hypertension was indirectly associated with cSVD through ICAD.

Interaction of serum uric acid with overweight on hypertension: findings from the China Health and Nutrition Survey

BackgroundBoth serum uric acid (SUA) levels and body mass index (BMI) are recognized as important risk factors for hypertension. The current study aimed to investigate the interaction effects between SUA levels and overweight (defined as BMI ≥ 24 kg/m2 in Chinese) on the incidence of hypertension among Chinese adults.Methods1124 hypertensive participants and 7283 non-hypertensive participants, extracted from the China Health and Nutrition Survey (CHNS), were analyzed. Participants were categorized based on their SUA levels and BMI, to investigate the interaction effects between SUA levels and overweight on hypertension.ResultsIn comparison with the reference group (BMI < 24 kg/m2 and in the 1st quintile of SUA), multivariable adjusted analysis demonstrated that the odds ratio (OR) (95% confidence interval, 95% CI) of hypertension for participants with overweight alone was 2.18 (1.41–3.37); for elevated SUA levels alone, the ORs (95% CIs) were 1.57 (1.08–2.30), 1.84 (1.24–2.74), 2.21 (1.47–3.32), and 2.48 (1.55–3.96) across SUA quintiles; and for the combined effect of higher SUA levels and overweight, the ORs (95% CIs) were 3.25 (2.19–4.82), 3.73 (2.51–5.55), 5.17 (3.42–7.80), and 6.21 (4.01–9.60). The relative excess risk due to interaction (RERI) was 3.26 (1.43–5.09) at the 5th quintile of SUA, indicating the presence of additive interaction between overweight and SUA levels on hypertension.ConclusionInteraction between SUA levels and overweight on hypertension exists specifically at the highest quintile (Q5, > 6.39 mg/dL) of SUA among Chinese adults. Therefore, strategies to lower SUA levels could be considered as a potential approach to mitigate hypertension risk in overweight individuals within this specific subgroup.

The triglyceride glucose: high-density lipoprotein cholesterol ratio is associated with coronary artery calcification evaluated via non-gated chest CT

BackgroundCoronary artery calcification (CAC) is a common risk factor of cardiovascular disease. Although triglyceride glucose (TYG) index and high-density lipoprotein cholesterol (HDL-c) are both associated with CAC, no study has evaluated the correlation between the TYG/HDL-c ratio and CAC. In the present study, we investigated the relationships between CAC and the TYG index and the TYG/HDL-c ratio.MethodsA total of 9585 participants who underwent computed tomography (CT) screening for lung cancer from 2018 to 2020 were included in this cross-sectional study. Demographic data, laboratory test data and medical history data were collected from medical records. TYG = Ln[fasting glucose (mg/dL)×fasting TG (mg/dL/2]. The triglyceride glucose-HDL-c ratio was calculated as TYG/HDL-c. CAC was evaluated on chest CT images. Multivariate logistic regression analysis and restricted cubic splines were used to determine the relationships among the TYG index, TYG/HDL-c ratio and risk of CAC. The receiver operating characteristic (ROC) curve was used to evaluate the performance of the TYG index and TYG/HDL-c ratio in identifying CACs in individuals aged 60 years and above.ResultsCAC was detected in 2515 of 9585 participants (mean age 51.8 ± 15.5 years, 61.2% men). The prevalence of CAC was significantly greater in participants with a high TYG/HDL-c ratio (32.6% in the fourth quartile vs. 19.1% in the first quartile, p < 0.001). Multivariate logistic regression revealed that both the TYG index (odds ratio (OR) = 1.06, 95% confidence interval (CI): 1.02–1.10) and the TYG/HDL-c ratio were associated with coronary artery calcification (OR = 1.32, 95% CI: 1.14–1.51). No such association was observed between the TYG index and CAC when further adjusted for the serum lipid level (OR = 1.23, 95% CI: 0.99–1.54). The TYG/HDL-c ratio was still associated with CAC after further adjustment for low-density lipoprotein cholesterol and total cholesterol (OR = 1.21, 95% CI: 1.09–1.35). TYG/HDL-c ratio was associated both with single vessel and multivessel calcification (OR = 1.14, 95%CI:1.05–1.23; OR = 1.15, 95%CI: 1.05–1.21). Similar trends were observed when we categorized individuals by TYG index and TYG/HDL-c quartiles and in subjects older than 60 years. Restricted cubic splines revealed that the TYG/HDL ratio had a better dose‒responsive relationship than did the TYG index. Subgroup analysis revealed that the association between the TYG/HDL-c ratio and coronary artery calcification was mainly observed in nondiabetic or nonhypertensive participants, regardless of low-density lipoprotein cholesterol levels. The ROC curve also revealed that the TYG/HDL-c ratio was better able to identify CAC than the TYG index was (area under the curve = 0.54 vs. 0.52, p < 0.01) in subjects older than 60 years.Conclusion An increase in the TYG/HDL-c ratio is significantly positively associated with the risk of CAC, and the TYG/HDL-c ratio has a more stable association with CAC than TYG.

P218 MAY MEASUREMENT MONTH 2019: BLOOD PRESSURE VARIABILITY AND ITS RELATIONSHIP WITH HYPERTENSION AND COMORBIDITIES

Background and Objective: Within-visit blood pressure variability (BPV) is a predictor of cardiovascular events, independent of mean blood pressure (BP) levels. This study explored the associations of BPV with hypertension status and comorbidities in May Measurement Month (MMM) 2019 global survey participants. Methods: Adults (≥18 years) were surveyed via convenience sampling from 92 countries in May 2019. Each participant had up to three standardized seated BP readings. Participants with incomplete data on age or sex, or any missing BP readings were excluded. Hypertension was defined as having a BP ≥140 and/or 90 mmHg or being treated with BP-lowering medication. Participants were stratified into three groups: normotensive, untreated hypertensives, treated hypertensives, and normotensives. BPV was calculated as the variation independent of the mean (VIM) of the three BP readings. Associations between BPV and each of three conditions (previous stroke, previous myocardial infarction, or diabetes) were modelled using linear regression. Each model was adjusted for mean BP, age, sex, and an interaction term between age and sex. Results: Data from 1,128,889 participants were included. The mean age was 45.2 (SD 16.6) years and 51.4% were female. A third (33.6%) of participants were hypertensive, of whom 200,370 (53.2%) were treated. Of non-hypertensive and untreated hypertensive participants, those with a history of stroke, myocardial infarction, or diabetes had lower BPV relative to those without a history of these conditions (Figure). A stronger association was observed for diabetes within untreated hypertensive than non-hypertensive participants. However, amongst treated hypertensive participants, differences in BPV between those with comorbid conditions and those without were smaller than in the other two groups. Conclusions: Contrary to expectation, BPV was significantly lower in those with diabetes, or a history of stroke or myocardial infarction, amongst both untreated hypertensives and normotensives. However, among treated hypertensives, BPV was similar between those with or without each comorbidity, suggesting a modifying effect of BP-lowering medication.

Postprandial hypotension is more common than orthostatic hypotension in older adults with dementia with lewy bodies: a cross-sectional study

Cardiovascular autonomic dysfunction is one of the supportive clinical features in dementia with Lewy bodies (DLB). This study aimed to investigate the frequency of postural and postprandial hypotension in people with DLB. The study group comprised 125 patients with DLB (76 females; mean age 78.4 ± 7.1 years) and 122 controls (88 females; mean age 74.4 ± 6.9 years). Postprandial blood pressure changes were assessed by ambulatory 24-hour blood pressure monitorization. Postural blood pressure changes were assessed via the head-up tilt table test. The frequency of postprandial hypotension (PPH) and orthostatic hypotension (OH) was higher in patients with DLB compared to controls (89.4% vs 51.7%; p < 0.001, and 45.5% vs 27.9%; p = 0.004, respectively) whereas the frequency of supine hypertension (SH), and orthostatic hypertension (OHT) was similar. However, SH in non-hypertensive participants was higher in DLB patients than in controls (48.9%, 25.7%; p = 0.035). PPH and OH were independently associated with a diagnosis of DLB (odds ratio [OR]:10.26 confidence interval [CI]%95 3.02–34.82; p < 0.001, and OR:2.22 CI%95 1.2–4.12; p = 0.012, respectively) after adjustment for age, number of medications, use of anti-psychotics drugs, angiotensin receptor blockers, and beta blockers. In conclusion, the study demonstrated that PPH was the most common finding of cardiovascular autonomic dysfunction, followed by OH and SH in older patients with DLB. Given the potential complications of postural blood pressure changes and PPH in such patients, cardiovascular autonomic dysfunction should be evaluated in patients with DLB.

Multiple Environmental Exposures and the Development of Hypertension in a Prospective US-Based Cohort of Female Nurses: A Mixture Analysis.

We investigated the independent and joint associations between multiple environmental exposures and incident hypertension in a US nationwide prospective cohort of women: the Nurses' Health Study II. We followed 107,532 nonhypertensive participants from 1989 to diagnosis of hypertension, loss to follow-up, death, or end of follow-up in June 2019. We applied Cox proportional hazards models to assess associations of incident hypertension with time-varying residential exposure to air pollution, noise, surrounding greenness, temperature, and neighborhood socioeconomic status (nSES), adjusting for potential confounders and coexposures. We evaluated the joint association of simultaneous exposure using quantile g-computation. We observed 38,175 hypertension cases over 2,062,109 person-years. Increased hypertension incidence was consistently associated with lower nSES and higher levels of fine particles (PM2.5) and nighttime noise exposures: hazard ratio (HRs) and 95% confidence intervals (CIs) of 1.06 (1.04, 1.08), 1.04 (1.01, 1.07), and 1.01 (1.00, 1.03), respectively, per interquartile range change. Joint HR for a one-quartile change in simultaneous exposure to the mixture was 1.05 (95% CI: 1.02, 1.09), assuming additivity, or 1.13 (95% CI: 1.06, 1.20), considering potential interactions within the mixture. Hypertension prevention should focus on enhancing nSES and reducing PM2.5 and noise levels, recognizing that reducing the overall exposures may yield additional benefits.

Relationship of quality and duration of sleep with arterial hypertension in a Colombian population

Introduction. Alterations in the quality and duration of sleep are risk factors for the development of arterial hypertension in Eastern countries. However, in Latin America there are few studies researching this association. Objective. To analyze the association between the quality and duration of sleep and the rate of arterial hypertension in a Colombian population. Materials and methods. An observational, longitudinal, prospective and analytical study nested in the INEFAC population-based cohort, was conducted with participants over 18 years of age from Bucaramanga (Colombia). Sleep quality was assessed using the Pittsburgh Sleep Quality Index. Sleep duration was assessed using standardized questions. Multivariate analysis was performed with logistic regression models adjusted for possible confounding variables. Results. A total of 1,306 non-hypertensive participants with a mean age of 40 ± 12 years were included. In this population, 92.8% had one or more sleep issues. 45.15% slept 6 hours or less and 28.6% slept 8 hours or more. Multivariate analysis showed a higher risk of hypertension in participants with diabetes (OR = 5.27; 95% CI: 2.27-12.26), obesity (OR = 2.81; 95% CI: 1.11-7.13), active smoking (OR = 2.02; 95% CI: 1.01-4.04) and higher socioeconomic level (OR = 4.94; 95% CI: 1.59-15.38 for level 4), but no higher risk was found in participants with poor sleep quality or short sleep duration. Conclusions. No association was found between the duration or quality of sleep and the rate of arterial hypertension in the Colombian population. More studies are required in this population to reach definitive conclusions.

Effect of Yogurt Intake Frequency on Blood Pressure: A Cross-Sectional Study.

Yogurt consumption is a significant factor in reducing the risk of hypertension and preventing cardiovascular diseases. Although increasing evidence has emerged regarding the potential benefits of probiotics in hypertension, there is a lack of large, cross-sectional studies assessing the association between yogurt intake and blood pressure parameters. We aimed to evaluate the association between yogurt intake frequency and blood pressure. A cross-sectional study was designed using data from the National Health and Nutrition Examination Survey from 2003 to 2004 and 2005 to 2006. We included 3, 068 adults with blood pressure data and yogurt intake data. Multivariate regression analyses revealed significant inverse associations between yogurt and systolic blood pressure (P < 0.05), diastolic blood pressure (P < 0.05), and mean arterial pressure (P < 0.05) in nonhypertensive participants (n = 1 822) but not in hypertensive participants (n = 1 246). Furthermore, a high frequency of yogurt intake prevented hypertension; however, no additional antihypertensive effects were observed in patients already diagnosed with hypertension.

Beneficial impact of visual stimulation-based digital therapeutics on blood pressure control in non-hypertensive individuals.

Hypertension-related diseases occur in both hypertensive and non-hypertensive individuals. However, few studies to date have explored blood pressure (BP) control in non-hypertensive individuals. This before-after study aimed to examine the impact of visual stimulation-based digital therapeutics (VS-DTx) on BP and heart rate (HR). Eighty-three eligible non-hypertensive participants were included in this study. The McNemar test and Paired Samples Wilcoxon Signed Rank Test were employed to assess decline rates and differences in BP and HR between the control phase and the intervention (using VS-DTx) phase. Pairwise correlation analysis was used to analyze the correlation between the two phases. This study found the systolic BP (SBP) and mean arterial pressure (MAP) in the VS-DTx phase showed a downward trend (66.2% vs 49.3%; 68.7% vs 55.4%). The mean SBP decreased from 114.73 mm Hg to 111.18 mm Hg, and the mean MAP decreased from 87.96 mm Hg to 84.88 mm Hg in the VS-DTx phase. Paired Samples Wilcoxon Test showed differences in both ΔSBP (Z = -3.296; P < 0.01) and ΔMAP (Z = -2.386; P < 0.05) (Δ is defined as the difference between baseline and post-stimulus). The pairwise correlations analysis revealed that VS-DTx affected the MAP reduction (r = 0.33; P < 0.01) between the browsing digital devices phase and the VS-DTx phase. The results indicated that VS-DTx may have a certain effect on BP, including SBP and MAP. This study preliminarily explored the possible effects of VS-DTx on BP, providing certain useful insights for future research in digital BP management.

Susceptibility of hypertensive individuals to acute blood pressure increases in response to personal-level environmental temperature decrease

BackgroundEnvironmental temperature is negatively associated with blood pressure (BP), and hypertension may exacerbate this association. The aim of this study is to investigate whether hypertensive individuals are more susceptible to acute BP increases following temperature decrease than non-hypertensive individuals. MethodsThe study panel consisted of 126 hypertensive and 125 non-hypertensive (n = 251) elderly participants who completed 940 clinical visits during the winter of 2016 and summer of 2017 in Beijing, China. Personal-level environmental temperature (PET) was continuously monitored for each participant with a portable sensor platform. We associated systolic BP (SBP) and diastolic BP (DBP) with the average PET over 24 h before clinical visits using linear mixed-effects models and explored hourly lag patterns for the associations using distributed lag models. ResultsWe found that per 1 °C decrease in PET, hypertensive individuals showed an average (95 % confidence interval) increase of 0.96 (0.72, 1.19) and 0.28 (0.13, 0.42) mmHg for SBP and DBP, respectively; and non-hypertensive participants showed significantly smaller increases of 0.28 (0.03, 0.53) mmHg SBP and 0.14 (-0.01, 0.30) mmHg DBP. A lag pattern analysis showed that for hypertensive individuals, the increases in SBP and DBP were greatest following lag 1 h PET decrease and gradually attenuated up to lag 10 h exposure. No significant BP change was observed in non-hypertensive individuals associated with lag 1–24 h PET exposure. The enhanced increase in PET-associated BP in hypertensive participants (i.e., susceptibility) was more significant in winter than in summer. ConclusionsWe found that a decrease in environmental temperature was associated with acute BP increases and these associations diminished over time, disappearing after approximately 10 hours. This implies that any intervention measures to prevent BP increases due to temperature drop should be implemented as soon as possible. Such timely interventions are particularly needed for hypertensive individuals especially during the cold season due to their increased susceptibility.

The Association of M235T Genetic Polymorphism in Angiotensinogen Gene and Other Non-Genetic Factors with Essential Hypertension among Jordanian Patients.

Hypertension, characterized by elevated pressure, poses a significant health risk. Recent studies in Jordan highlight high hypertension rates, emphasizing the need for genetic investigations to comprehend essential hypertension determinants. The AGT gene, part of the Renin Angiotensin System, is linked to blood pressure regulation. Limited information exists on the frequency of this polymorphism among Jordanian hypertensive patients. This study explores the association between the AGT M235T polymorphism and essential hypertension in Jordan. A cross-sectional study with 435 participants (199 hypertensive, 236 non-hypertensive) was conducted at the University of Jordan Hospital. Blood pressure was measured, and genetic analysis of the AGT M235T polymorphism was completed using the PCR-RFLP technique. Chi-square and t-tests were used for comparisons using SPSS software. Hypertensive patients exhibited significantly higher weight, BMI, and blood pressure. Genotyping results showed no significant difference (p > 0.05, Chi-square) in AGT M235T polymorphism distribution between control and patient groups. In addition, allele frequencies showed comparable patterns (p > 0.05, Chi-square). All genotype frequencies showed no deviation from the Hardy-Weinberg equation (p > 0.05, Chi-square). The AGT M235T genetic polymorphism is not more prevalent among hypertensive patients in Jordan, although the average weight and BMI among hypertensive patients is higher than the non-hypertensive participants. Obesity can be addressed as a potential risk factor for essential hypertension in Jordan. In addition, it is recommended to find out the influence of the AGT M235T genetic polymorphism on the response of antihypertensive drugs among hypertensive patients in Jordan.

Relationship of hypertension with dietary intake of calcium, magnesium, Vitamin D and Vitamin E among adult males

ABSTRACT Aims: Hypertension remains a main cause of premature death worldwide. Micronutrients are crucial in the regulation of blood pressure, therefore, we aimed to examine the associations between calcium, magnesium, Vitamin D, and Vitamin E intakes and hypertension among adult males. Settings and Design: Community-based, descriptive study. Materials and Methods: The study included 450 men with a mean age of 46.79 ± 15.88. Anthropometric measurements and body composition were assessed. An automated arm digital sphygmomanometer was used to monitor the resting heart rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP) values. Dietary intake including Ca, Mg, Vitamin D, and Vitamin E were assessed using a validated food frequency questionnaire (FFQ). The population sample was divided into two groups according to hypertension status as follows: hypertensive and normotensive groups. Statistical Analysis Used: The independent t-test was performed to assess the differences between the hypertensive and the normotensive groups. Results: The hypertensive participants were older and had a higher mean body mass index, fat %, SBP, DBP, pulse pressure and heart rate compared with nonhypertensive participants. Among micronutrient intake, hypertensive group had significantly higher Vitamin D intake than the normotensive group. Conclusions: This study found a significant association between Vitamin D intake, as assessed using FFQ, and hypertension, but not between Ca, Mg, or Vitamin E. To clarify the potential association between micronutrient intake and hypertension, more studies, and clinical trials should be conducted.

Correlation of D-dimer Levels with Fasting Blood Glucose Levels in Patients with Type 2 Diabetes Mellitus

Chronic hyperglycemia in patients with Type 2 Diabetes Mellitus (T2DM) can cause damage to various organs, resulting in both microvascular and macrovascular complications that lead to an increased risk of cardiovascular disease. One of the markers that can detect vascular disorders is D-dimer levels. Fasting blood glucose (FBG) analysis in T2DM patients associated with D-dimer levels is important to know to be used as an indicator in connection with diabetes complications, especially vascular complications. This study aims to determine the correlation between D-dimer levels and FGB. The study was conducted in three hospitals in North Sulawesi province. The study population was T2DM patients (as evidenced by fasting blood glucose &gt;126mg/dL) who examined themselves in the period January-June 2023. Samples were obtained using the total sampling method, where all populations that met the inclusion and exclusion criteria were used as participants. Ninety-four patients with T2DM (62 women and 32 men) were eligible to be participants in this study. Blood pressure, GDP and D-dimer were examined. Based on the results of the blood pressure examination, 40 participants suffered from hypertension and 54 participants did not. The average values of blood glucose, HbA1c and D-dimer levels in hypertensive and non-hypertensive participants are not much different. The results of the analysis using Spearman's rho showed that there was a moderate correlation between D-dimer levels and GDP (p=0.03, r=0.302). In conclusion, although there is a moderate correlation between D-dimer levels and fasting blood glucose levels, D-dimer is not recommended to be used as an indicator of complications in T2DM.

Short-term echocardiographic follow-up after hospitalization for COVID-19: a focus on early post-acute changes.

Impaired physical functional status is one of the typical long-term sequelae of COVID-19 infection that significantly affects the quality of life and work capacity. Minor changes in cardiac structure and function that are unable to cause the manifestation of overt heart failure may remain undetected in COVID-19 convalescents, at the same time potentially contributing to the persistence of symptoms and development of long COVID syndrome. To study the typical features and short-term dynamics of cardiac remodeling and possible signs of cardiac dysfunction following hospitalization for COVID-19. This is a combined cross-sectional and longitudinal cohort study in which 176 hospitalized patients (93 female and 83 male, mean age 53.4 ± 13.6 years) with COVID-19 infection underwent comprehensive transthoracic echocardiography pre-discharge (22.6 ± 7.1 days from the onset of symptoms) with repeated evaluation after 1 month. The control group included 88 age-, sex-, height- and weight-matched healthy individuals, with a subset of those (n = 53) matched to the subset of non-hypertensive study participants (n = 106). Concentric left ventricular geometry was revealed in 59% of participants, including 43% of non-hypertensive subjects; predominantly Grade I diastolic dysfunction was found in 35 and 25% of patients, respectively. Other findings were naturally following from described phenotype of the left venticle and included a mild increase in the absolute and relative wall thickness (0.45 ± 0.07 vs. 0.39 ± 0.04, p < 0.001), worsening of diastolic indices (e' velocity 9.2 ± 2.2 vs. 11.3 ± 2.6 cm/s, p < 0.001, E/e' ratio 7.5 ± 1.8 vs. 6.8 ± 1.7, p = 0.002) and global longitudinal strain (17.5 ± 2.4 vs. 18.6 ± 2.2, p < 0.001). No significant improvement was found on re-evaluation at 1 month. Hospitalized patients recovering from COVID-19 were characterized by a high prevalence of left ventricular concentric remodeling, predominantly Grade I diastolic dysfunction, and a mild decrease in the longitudinal systolic function. These changes were less frequent but still prevalent in the non-hypertensive subgroup and largely persisted throughout the 1-month follow-up.

Relationship between hypertension/blood pressure and hearing sensitivity among drivers: A correlation analysis.

One of the most common chronic diseases is hypertension. The majority of research has linked hearing loss to hypertension. However, the relationship between hypertension and hearing is still unknown. The primary goal of the study is to investigate the effect of hypertension on hearing and to find out the association between blood pressure levels and auditory health in auto-rickshaw drivers. The study utilized 121 healthy professional auto-drivers between the age range of 25 and 55 years. Pure-tone audiometry (PTA) and extended high-frequency audiometry (EHFA) were used to determine the participants' hearing thresholds from 0.25 to 16 kHz. The cochlear hair cell functioning was evaluated using distortion-product otoacoustic emission (DPOAE) testing. Blood pressure (mmHg) measurements were categorized under hypertension stage (normal (120; <80); elevated (120-129; <80); hypertension - stage 1 (130-139; 80-89); hypertension - stage 2 (≥140; ≥90)). The mean age of the study participants was 42.17 ± 9.03 years. The mean systolic and diastolic BP of all the study participants were 138.24 ± 19.73 (105-216) mmHg and 87.69 ± 12.14 (60-134) mmHg, respectively. BP levels were normal for 17.4% (N = 21) of the study participants, 21.5% (N = 26) had elevated blood pressure, 21.5% (N = 26) of the population falls under stage 1 hypertension, and 39.7% (N = 48) had stage 2 hypertension. Our study discovered a significant difference between main group effects and no significant difference between group interaction effects. Hearing thresholds were significantly higher in hypertensive participants compared to non-hypertensive participants. However, there was no statistically significant relationship between the two variables hypertension and hearing loss. Implementing health promotion initiatives and raising awareness about hearing health could improve the quality of life for a high-risk occupational group of drivers.

Association of low-dose aspirin use for primary prevention with self-reported kidney stones prevalence: a cross-sectional study.

To investigate the association between low-dose aspirin use for primary prevention and self-reported kidney stones prevalence in the 40-79years old population. We conducted a cross-sectional study based on the United States population data from the National Health and Nutrition Examination Survey 2011-2018. Baseline demographical and clinical data were collected. The univariate and multivariate regression was performed to identify confounding factors and assess the relationship between aspirin use for primary prevention and the prevalence of self-reported kidney stones. A propensity-score matching was used to identify patients with similar baseline characteristics to adjust for the bias caused by confounding factors. A total of 10,256 low-dose aspirin-use participants were included in this study. 10.4% of participants reported a history of kidney stones, and 18.5% reported a continuous use of low-dose prophylactic aspirin. Multivariate logistic regression analysis showed that low-dose preventive aspirin use had significantly increased the odds of self-reported kidney stones (OR = 1.245; 95% CI: 1.063-1.459; p = 0.007). In subgroup analysis, this finding was primarily limited to males (OR = 1.311), non-hypertensive participants (OR = 1.443), diabetic participants (OR = 1.380), and older (60 ≤ Age < 80) (OR = 1.349). The propensity-score matched analyses supported this result after adjusting for the bias caused by potential confounders (OR = 1.216; 95% CI: 1.011-1.462; p = 0.038). In this study, there exists a significant relationship between low-dose aspirin for primary prevention and self-reported kidney stones, primarily among males, no hypertensive participants, diabetics, or older adults. Further studies are needed to elucidate the mechanisms underlying these findings in the future.

Risk Factors for Hyperuricemia or Gout in Men and Women: The Circulatory Risk in Communities Study (CIRCS).

We aimed to examine sex-specific risk factors for hyperuricemia or gout in Japanese cohorts. We followed up 3,188 men (mean age, 55.6 years) and 6,346 women (mean age, 54.1 years) without hyperuricemia, gout, or elevated liver enzymes at baseline from 1986 to 1990 for a median of 14.6 years. The participants were considered as having hyperuricemia or gout if their serum uric acid levels were ≥ 7.0 mg/dL or they were receiving treatment for hyperuricemia or gout during annual health checkups. The sex-specific multivariable hazard ratios (HRs) of hyperuricemia or gout incidence were calculated after adjustment for smoking and drinking status, body mass index, hypertension, diabetes, hypercholesterolemia, and hypertriglyceridemia using the Cox proportional-hazard model. During follow-up, 733 men and 355 women had hyperuricemia or gout. Among men, the multivariable HRs (95% confidence intervals) of hyperuricemia or gout were 1.23 (1.00-1.52) and 1.41 (1.13-1.75) for drinkers of ＜46 and ≥ 46 g ethanol/day, respectively, compared with non-drinkers; 1.00 (0.81-1.24) and 1.18 (0.93-1.50) for smokers of 1-19 and ≥ 20 cigarettes/day, respectively, compared with never smokers; and 1.41 (1.20-1.65) for hypertensive compared with non-hypertensive participants. The HRs for women were 1.02 (0.70-1.48), 1.66 (1.05-2.63), and 1.12 (0.88-1.42) for current drinkers, current smokers, and hypertensive participants, respectively. For both men and women, body mass index, diabetes, hypercholesterolemia, and hypertriglyceridemia were not associated with hyperuricemia or gout incidence. Hypertension and alcohol drinking are risk factors for hyperuricemia or gout among men and smoking among women.

A retrospective cross-sectional study of the prevalence of hypertension and its co-morbidities in a Nigerian medical center

Introduction: Hypertension is a major risk factor for other life threatening conditions like stroke, myocardial infarction, cardiac failure, vascular disease, and chronic kidney disease. Many times, hypertension presents with other comorbidities further worsening prognosis and quality of life of the patients. Objectives: The aim of this research was to evaluate the prevalence of hypertension and other comorbidities among patients accessing specialist care. Method: A cross sectional design which obtained data from case files of patients who visited the hospital for follow-up in August, 2022. 251 participants were selected by randomization technique. Analyses were done using RStudio version 4.2.1 at 95% confidence interval and 0.05 level of significance. Result: The results showed that, 50.6% of the participants were males, the mean age of the participants was 53 years with a mean BP of 126.2/77.7 mmHg. The Tiv ethnicity formed the majority (57.8%) of the sample population. The prevalence of hypertension was estimated at 54.2%. A linear correlation was found between SBP and age adjusted for marital status among non-hypertensive participants (R2 = 26.3%, p&lt;0.05). Diabetes was the most prevalent comorbidity (24.3%). ACE inhibitors and ARBs were the most prescribed antihypertensive agents (72.8%) with dual therapy (41.2%) being the most utilized pharmacotherapeutic approach. Only about 61.8% hypertensive participants had their BP under control. In conclusion: The prevalence of hypertension was high in the FMC, Makurdi. A positive linear correlation between SBP and age was seen. Although the outcome rate was above average, it was still seen as a huge public health concern.

Changes in the level of cytokines in the saliva of hypertensive patients with chronic periodontitis after scaling and root planning

IntroductionCytokines have a key role in the pathogenesis of both hypertension and periodontitis. Salivary diagnosis is a promising field with numerous clinical applications. Since limited studies have been carried out on how salivary inflammatory cytokines can be determined and how well periodontal disease and hypertension might react to scaling and root planning (SRP). The goal of this study was to identify the pattern of changes in salivary inflammatory cytokines in chronic periodontitis subjects with hypertension after nonsurgical periodontal therapy. MethodsIt included observational trial recruited 94 chronic periodontitis patients, 44 of whom had hypertension. All subjects have undergone non- surgical periodontal treatment. The clinical periodontal parameters included gingival index (GI), plaque index (PI), and probing of pocket depth (PPD). Unstimulated saliva was collected to determine the inflammatory biomarkers (using a commercial Elisa kit) both before and after SRP ResultsIn comparison to non-hypertensive participants, the periodontal PPD was significantly higher in hypertensive subjects. All clinical parameters in the first examination, except for PI, were significantly higher in hypertensive than in non-hypertensive subjects. Plaque Index, GI, and PPD parameters at first visit and after finishing treatment positively correlated with salivary IL-1β, excluding pretreatment GI. The current results demonstrate the presence of a positive correlation between diastolic blood pressure and TNF (r = 0.330 and P = 0.029). All patients enrolled in this study showed a significant increase in the salivary levels of IL-4 after SRP. ConclusionsThe current study offer important and valuable information concerning the practical application of pro-inflammatory and anti-inflammatory cytokines as useful biomarkers and indicators for determining the outcome of SRP and progression of chronic periodontitis in patients with hypertension.

Sinovac COVID-19 Side Effects in Hypertensive Patients: An Observational Study From Pakistan.

Background The most important factor in combating the coronavirus disease 2019 (COVID-19) pandemic was the provision ofsafe and effective vaccines. The acceptance of vaccines is impacted by several variables, including beliefs about the vaccine's safety and adverse effects. Vaccine side effects can vary depending on the type, but they are often moderate, localized, transient, and self-limiting. Therefore, this study aimed to assess the prevalence of side effects experienced after receiving the Sinovac vaccine by participants hypertensive and non-hypertensive participants. Methodology This was a cross-sectional, multicenter study that was performed using non-probability sampling. The study duration was six months from May 1, 2022, to October 31, 2022. The study involved 600 individuals who had either received the first or second dose of the Sinovac vaccine. For categorical data, frequencies and percentages were documented. The chi-square test was applied to determine the association between local and systemic side effects among hypertensive and non-hypertensive participants. Results The study findings showed that out of 600 participants, there were 187 (62.3%) males and 113 (37.7%) females with hypertension, and 222 (74.0%) males and 78 (26.0%) females without hypertension, with a significant association(p = 0.002). Following the first dose of the Sinovac vaccine, fever was the most commonly reported side effect in 153 (51.0%) hypertensive participants and 62 (20.7%) non-hypertensive participants, with a significant association(p < 0.001). Similarly, following the second dose of the Sinovac vaccine, fever was the most commonly reported side effect in 108 (36.0%) hypertensive participants and 57 (19.0%) non-hypertensive participants, with a significant association(p < 0.001). Conclusions This study concluded that the presence of hypertension significantly increased the manifestations of local and systemic side effects compared with non-hypertensive participants. Moreover, fever, pain, and swelling at the injection site were the most commonly reported side effects after receiving the first and second doses of the Sinovac vaccine.
