Hypertension in China: burdens, guidelines and policy responses: a state-of-the-art review

Risk factors for fasting blood glucose control in middle-aged and elderly type 2 diabetes patients

This study aimed to investigate and analyze the medication use, fasting blood glucose control, and associated risk factors among residents with type 2 diabetes at the grassroots level in Xinjiang Production and Construction Corps. A multi-stage cluster sampling method was employed to conduct a questionnaire survey among residents aged 45 and above in battalions (communities) as the smallest unit. The medication use was recorded, and fasting blood glucose control was considered as the dependent variable. Logistic regression analysis was performed to identify the risk factors influencing fasting blood glucose control among different population characteristics. A total of 2316 participants were included in the study, of which 1072 were male (45.12%), 1418 were aged 65 and above (61.23%), 2031 were Han Chinese (87.69%), and 1551 were from the surrounding areas of Urumqi (66.97%). The main medications used among the top three classes were metformin, insulin, and α-glucosidase inhibitors. The treatment rate for type 2 diabetes was 71.80%, and the fasting blood glucose control rate was 27.98%. Multivariate analysis identified living outside the Urumqi surrounding area, age 65 and above, body mass index ≥ 24, abnormal blood lipids, and untreated hypertension as independent risk factors for poor fasting blood glucose control, while treatment was a protective factor for achieving blood glucose control. The treatment rate and fasting blood glucose control rate among grassroots residents with type 2 diabetes in Xinjiang Production and Construction Corps need improvement. Efforts should be made to enhance patient medication adherence and health management awareness through education. Targeted interventions should be implemented for high-risk populations with identified risk factors to reduce or delay the occurrence of diabetes and its complications, ultimately aiming to reduce mortality rates and improve quality of life.

Assessment of EMR ML Mining Methods for Measuring Association between Metal Mixture and Mortality for Hypertension

INTRODUCTION

There are limited data available regarding the connection between heavy metal exposure and mortality among hypertension patients.

AIM

We intend to establish an interpretable machine learning (ML) model with high efficiency and robustness that monitors mortality based on heavy metal exposure among hypertension patients.

METHODS

Our datasets were obtained from the US National Health and Nutrition Examination Survey (NHANES, 2013-2018). We developed 5 ML models for mortality prediction among hypertension patients by heavy metal exposure, and tested them by 10 discrimination characteristics. Further, we chose the optimally performing model after parameter adjustment by genetic algorithm (GA) for prediction. Finally, in order to visualize the model's ability to make decisions, we used SHapley Additive exPlanation (SHAP) and Local Interpretable Model-Agnostic Explanations (LIME) algorithm to illustrate the features. The study included 2347 participants in total.

RESULTS

A best-performing eXtreme Gradient Boosting (XGB) with GA for mortality prediction among hypertension patients by 13 heavy metals was selected (AUC 0.959; 95% CI 0.953-0.965; accuracy 96.8%). According to sum of SHAP values, cadmium (0.094), cobalt (2.048), lead (1.12), tungsten (0.129) in urine, and lead (2.026), mercury (1.703) in blood positively influenced the model, while barium (- 0.001), molybdenum (- 2.066), antimony (- 0.398), tin (- 0.498), thallium (- 2.297) in urine, and selenium (- 0.842), manganese (- 1.193) in blood negatively influenced the model.

CONCLUSIONS

Hypertension patients' mortality associated with heavy metal exposure was predicted by an efficient, robust, and interpretable GA-XGB model with SHAP and LIME. Cadmium, cobalt, lead, tungsten in urine, and mercury in blood are positively correlated with mortality, while barium, molybdenum, antimony, tin, thallium in urine, and lead, selenium, manganese in blood is negatively correlated with mortality.

Genome-Wide Identification of Seven in Absentia E3 Ubiquitin Ligase Gene Family and Expression Profiles in Response to Different Hormones in Uncaria rhynchophylla

SINA (Seven in absentia) E3 ubiquitin ligases are a family of RING (really interesting new gene) E3 ubiquitin ligases, and they play a crucial role in regulating plant growth and development, hormone response, and abiotic and biotic stress. However, there is little research on the SINA gene family in U. rhynchophylla. In this study, a total of 10 UrSINA genes were identified from the U. rhynchophylla genome. The results of multiple sequence alignments and chromosomal locations show that 10 UrSINA genes were unevenly located on 22 chromosomes, and each UrSINA protein contained a SINA domain at the N-terminal and RING domains at the C-terminal. Synteny analysis showed that there are no tandem duplication gene pairs and there are four segmental gene pairs in U. rhynchophylla, contributing to the expansion of the gene family. Furthermore, almost all UrSINA genes contained the same gene structure, with three exons and two introns, and there were many cis-acting elements relating to plant hormones, light responses, and biotic and abiotic stress. The results of qRT-PCR show that most UrSINA genes were expressed in stems, with the least expression in roots; meanwhile, most UrSINA genes and key enzyme genes were responsive to ABA and MeJA hormones with overlapping but different expression patterns. Co-expression analysis showed that UrSINA1 might participate in the TIA pathway under ABA treatment, and UrSINA5 and UrSINA6 might participate in the TIA pathway under MeJA treatment. The mining of UrSINA genes in the U. rhynchophylla provided novel information for understanding the SINA gene and its function in plant secondary metabolites, growth, and development.

Pathogenesis of cardiovascular diseases: effects of mitochondrial CF6 on endothelial cell function

Cardiovascular disease (CVD) stands as a predominant global cause of morbidity and mortality, necessitating effective and cost-efficient therapies for cardiovascular risk reduction. Mitochondrial coupling factor 6 (CF6), identified as a novel proatherogenic peptide, emerges as a significant risk factor in endothelial dysfunction development, correlating with CVD severity. CF6 expression can be heightened by CVD risk factors like mechanical force, hypoxia, or high glucose stimuli through the NF-κB pathway. Many studies have explored the CF6-CVD relationship, revealing elevated plasma CF6 levels in essential hypertension, atherosclerotic cardiovascular disease (ASCVD), stroke, and preeclampsia patients. CF6 acts as a vasoactive and proatherogenic peptide in CVD, inducing intracellular acidosis in vascular endothelial cells, inhibiting nitric oxide (NO) and prostacyclin generation, increasing blood pressure, and producing proatherogenic molecules, significantly contributing to CVD development. CF6 induces an imbalance in endothelium-dependent factors, including NO, prostacyclin, and asymmetric dimethylarginine (ADMA), promoting vasoconstriction, vascular remodeling, thrombosis, and insulin resistance, possibly via C-src Ca2+ and PRMT-1/DDAH-2-ADMA-NO pathways. This review offers a comprehensive exploration of CF6 in the context of CVD, providing mechanistic insights into its role in processes impacting CVD, with a focus on CF6 functions, intracellular signaling, and regulatory mechanisms in vascular endothelial cells.

Association between high-altitude polycythemia and hypertension: a cross-sectional study in adults at Tibetan ultrahigh altitudes

The study aimed to evaluate the association between high-altitude polycythemia and hypertension in adults residing on Anduo County's plateau, which is located 4700 meters above sea level. A total of 387 individuals participated in the cross-sectional survey conducted between April and May of 2021. Interviews, physical inspections, and laboratory tests were employed to gather information about all of the subjects. The association between high-altitude polycythemia and hypertension was assessed using multivariable logistic regression models. The average age of the 387 participants was 32.6 ± 6.3 years. Of these participants, 260 (67%) were male. The overall prevalence of hypertension was 27.1% (57/380). When stratified by gender, the prevalence was 12.6% (16/127) in females and 34.2% (89/260) in males. The overall prevalence of high-altitude polycythemia was 19.6% (76/387). When stratified by gender, the prevalence was 26.2% (68/260) in males and 6.3% (8/127) in females. During logistic regression analysis, we found that participants with elevated hemoglobin per 10 g/L had a 26% greater risk of hypertension (adjusting for odds ratio [OR], 1.26; 95% confidence interval [CI], 1.11-1.44). Additionally, high-altitude polycythemia greatly increased the risk of hypertension in comparison to non-high-altitude polycythemia (OR, 3.01; 95% CI, 1.66-5.44, P < 0.001). The consistency of the results was further demonstrated by stratified and interaction analyses, showing that Hans individuals had a higher risk of hypertension. High-altitude polycythemia is positively associated with hypertension in adults residing at Tibetan ultrahigh altitudes. The results of the investigation may aid in the planning of future research and guide the development of targeted healthcare practices for high-altitude populations, particularly among Han Chinese residents of the Tibetan Plateau.

In Silico Screening of Bioactive Peptides in Stout Beer and Analysis of ACE Inhibitory Activity

Stout beer was selected as the research object to screen angiotensin-converting enzyme (ACE) inhibitory peptides. The peptide sequences of stout beer were identified using ultra-performance liquid chromatography-quadrupole-Orbitrap mass spectrometry with de novo, and 41 peptides were identified with high confidence. Peptide Ranker was used to score the biological activity and six peptides with a score ≥ 0.5 were screened to predict their potential ACE inhibitory (ACEI) activity. The toxicity, hydrophilicity, absorption, and excretion of these peptides were predicted. In addition, molecular docking between the peptides and ACE revealed a significant property of the peptide DLGGFFGFQR. Furthermore, molecular docking conformation and molecular dynamics simulation revealed that DLGGFFGFQR could be tightly bound to ACE through hydrogen bonding and hydrophobic interaction. Lastly, the ACEI activity of DLGGFFGFQR was confirmed using in vitro evaluation and the IC50 value was determined to be 24.45 μM.

Factors associated with knowledge of hypertension risk factors and symptoms among Gambian women: A cross-sectional study based on the Gambia Demographic and Health Survey

Background

We examined the factors associated with knowledge of hypertension risk factors and symptoms among Gambian women.

Methods

This cross-section study was based on 11, 865 female participants (aged 15-49 years) of The Gambia Demographic and Health Survey 2019-2020. We performed descriptive statistics, and multivariate-adjusted logistic regression models.

Results

Only 34.89 % and 36.82 % of the participants knew at least one risk factor and symptom of hypertension, respectively. Women who had never measured their blood pressure had a reduced odds of knowing a hypertension risk factor (OR = 0.68; 95 %CI: 0.60---0.77; P < 0.01) and symptom (OR = 0.56; 95 %CI: 0.49---0.64; P < 0.01). Compared to women with higher education, those with no education had a lower odds of knowing a hypertension risk factor (OR = 0.18; 95 %CI: 0.12---0.27; P < 0.01) and symptom (OR = 0.32; 95 %CI: 0.23---0.45; P < 0.01). Similarly, women who never used the internet had reduced odds of mentioning a hypertension risk factor (OR = 0.55; 95 %CI: 0.48---0.61; P < 0.01) and symptom (OR = 0.61; 95 %CI: 0.54---0.69; P < 0.01). Those who never watched television had decreased odds of knowing a hypertension risk factor (OR = 0.74; 95 %CI: 0.63--0.86; P < 0.01) and symptoms (OR = 0.68; 95 %CI: 0.58---0.80; P < 0.01). Conclusion: Fewer women could mention at least one hypertension risk factor and symptom. We also found that knowledge of hypertension risk factors and symptoms was associated with education level and socio-economic status.

Exercise interventions for the effect of endothelial function in hypertensive patients: A systematic review and meta-analysis

Endothelial dysfunction is crucial factor to the hypertension occurrence, and controversy remains regarding the effect of exercise on improving endothelial function in hypertensive patients. The authors used meta-analysis to evaluate the intervention effect of exercise on endothelial function in hypertensive patients and to investigate exercise protocols that may have a greater intervention effect. A total of 37 studies and a total of 2801 participants were included. The results were as follows: endogenous nitric oxide (NO)[SMD = .89, 95% CI (.48, 1.30), p < .0001], endothelin-1 (ET-1): [SMD = -.94, 95% CI (-1.15, -.73), p <. 0001], flow-mediated dilation (FMD) [SMD = -.57, 95% CI (.36, .79), p < .000001]. In subgroup analysis, high-intensity aerobic exercise, with a single exercise duration of 35-50 min, 3-4 times/week for a total of 10-12 weeks, had the largest amount of intervention effect on NO, and moderate-intensity resistance exercise, with a single exercise duration of ≥60 min, 6 times/week for a total of 15-18 weeks, had the largest amount of intervention effect on ET-1. In conclusion, exercise can improve NO levels, FDM levels, and reduce ET-1 secretion of hypertension patients, thereby improve their endothelial function. The ideal intervention effect of improving NO level was more likely to be obtained by taking the exercise prescription of high-intensity aerobic exercise with a single exercise duration of 35-50 min, 3-4 times/week for 10-12 weeks; the ideal intervention effect of improving ET-1 was more likely to be obtained by taking the exercise prescription of oderate -intensity resistance exercise with a single exercise duration of ≥60 min, 6 times/week for 15-18 weeks.

Insight into the status of plasma renin and aldosterone measurement: findings from 526 clinical laboratories in China

OBJECTIVES

Accurate measurements of renin and aldosterone levels play an important role in primary aldosteronism screening, which is of great importance in the management and categorization of hypertension. The objective of this study is to investigate the current status of plasma renin and aldosterone measurements in China, which is achieved by analyzing the results of 526 clinical laboratories nationwide for three pooled fresh plasma samples derived from more than 2,000 patients.

METHODS

Renin and aldosterone in three pooled plasma samples were measured four times in 526 laboratories employing various measurement systems. The inter- and intra-laboratory %CV were calculated and compared. To determine the source of the substantial inter-laboratory %CV, laboratories were categorized according to the measurement systems they are using, and both the inter- and intra-measurement-system %CV were calculated and compared.

RESULTS

Regarding renin, the majority of laboratories use four primary commercial immunoassays. However, for aldosterone, in addition to commercial immunoassays, laboratory-developed liquid chromatography-tandem mass spectrometry (LC-MS) methods are also used by laboratories. The median values of intra-laboratory %CVs, intra-measurement-system %CVs, inter-laboratory %CVs, and inter-measurement systems %CVs varied between 1.6 and 2.6 %, 4.6 and 14.9 %, 8.3 and 25.7 %, and 10.0 and 34.4 % for renin, respectively. For aldosterone, these values ranged from 1.4 to 2.2 %, 2.5-14.7 %, 9.9-31.0 %, and 10.0-35.5 %, respectively.

CONCLUSIONS

The precision within laboratories and measurement systems for plasma renin and aldosterone measurements is satisfactory. However, the comparability between laboratories using different measurement systems remains lacking, indicating the long way to achieve standardization and harmonization for these two analytes.

The effect of health coaching on blood pressure control and disease self-management among patients in rural area in China: a randomized controlled trial

The self-management education for patients with hypertension has not been widely provided in rural areas of China. Our study aimed to examine the effect of health coaching intervention on controlling BP and improving self-management skills among rural resident of ≤6 month-history of hypertension. A total of 102 participants were enrolled in the RCT. The control group received usual health guidance and follow-up management; the experimental group received health coaching and follow up management. The primary outcomes were the difference in changes of BP and mean self-management scores. The secondary outcomes included waist circumference, body mass index (BMI), and medication literacy. Participants in the experimental group showed a significantly greater improvement with respect to systolic BP and diastolic BP respectively (133.85 ± 4.74 mmHg vs 127.96 ± 5.42 mmHg;80.94 ± 5.52 mmHg vs 77.37 ± 4.44 mmHg, P < 0.05) and BMI (24.66 ± 2.19 kg/m2 vs 23.44 ± 2.05 kg/m2, P < 0.05) compared with the control group. A significant difference was also observed between the experimental and control groups in terms of self-management and medication literacy at both 3 and 6 months (P < 0.05). However, there was no significant difference in changes of waist circumferences between the two groups (22.6% vs 38.8%). In conclusion, for patients with diagnosed with hypertension within the last 6 months, health coaching maybe is an effective approach to control blood pressure and improve medication literacy and self-management skills.

Health literacy and high blood pressure among Myanmar migrant workers in Northeastern Thailand

Hypertension, related to serious consequences unless diagnosed and treated, is a global concern, also affecting migrant workers. Due to the high prevalence of hypertension among migrant workers in Thailand, the influences of health literacy and other factors on blood pressure were needed to explore among Myanmar migrant workers in Northeastern Thailand. Hence, this study aimed to identify the prevalence of high blood pressure (HBP), its association with health literacy and other factors among Myanmar migrant workers in Northeastern Thailand. A cross-sectional analytical study was conducted in Northeastern Thailand. A multistage sampling procedure was applied. Data was gathered through interviews utilizing validated and reliable structured questionnaire. Descriptive statistics and inferential statistics with multiple logistic regression were used. Among 406 participants, about 60% were male and about 70% of them were married. The prevalence of overall HBP was 63.3% (95% CI: 58.49-67.86), 52% in females and 71.86% in males. Participants with limited health literacy were 79% more likely to have HBP than those with excellent and adequate health literacy (AOR = 1.79, 95% CI: 1.13-2.84). Other factors substantially linked with having HBP were being male gender (AOR = 4.68, 95% CI: 2.81-7.78), being overweight (AOR = 2.23, 95% CI: 1.18-4.23), being obese (AOR = 5.69, 95% CI: 2.96-10.96), not having health insurance (AOR = 2.01, 95% CI: 1.11-3.66), staying in Thailand for more than 48 months (AOR = 2.4, 95% CI: 1.48-3.9), and having family history of hypertension (AOR = 2.07, 95% CI: 1.28-3.35). In conclusion, more than half of Myanmar migrant workers had HBP. Factors associated with HBP were limited health literacy, male gender, overnutrition, lack of health insurance, longer duration of stay in Thailand and having family history of hypertension. Therefore, there is a need for a multifaceted strategy to prevent hypertension and its consequences by promoting health literacy as well as by enhancing good behavioural practice among this community.

Psychometric properties of the Chinese version of the Hypertension Belief Assessment Tool

BACKGROUND

Hypertension is prevalent in China. Hypertensive patients suffer from many health problems in life. Hypertension is a common chronic disease with long-term and lifelong characteristics. In the long run, the existence of chronic diseases will affect the patient's own health beliefs. However, people's health beliefs about Hypertension are not explicit. Therefore, it is vital to find a suitable instrument to comprehend and improve the health beliefs of hypertensive patients, thus, better control of blood pressure and improvement of patient's quality of life are now crucial issues. This study aimed to translate the Hypertension Belief Assessment Tool (HBAT) into Chinese and examine the psychometric properties of the Chinese version of the Hypertension Belief Assessment Tool in hypertensive patients.

METHODS

This is a cross-sectional study. We translated the HBAT into Chinese and tested the reliability and validity of the Chinese version among 325 hypertensive patients.

RESULTS

The Chinese version of the scale contains 21 items. The Exploratory Factor Analysis (EFA) revealed six factors and explained 77.898% of the total variation. A six-factor model eventually showed acceptable fit indices in the Confirmatory Factor Analysis (CFA). With modified Confirmatory Factor Analysis, the fit indices were Chi-square/Degree of Freedom (CMIN/DF) = 2.491, Comparative Fit Index (CFI) = 0.952, Incremental Fit Index (IFI) = 0.952, Root-mean-square Error of Approximation (RMSEA) = 0.068, Tucker Lewis Index (TLI) = 0.941. The HBAT exhibits high internal consistency reliability (0.803), and the scale has good discriminant validity.

CONCLUSION

The results suggest that the HBAT is a reliable and valid instrument for assessing the beliefs of Chinese hypertensive patients.

Prevalence and factors associated with overweight, obesity and central obesity among adults in Shenmu City, Shaanxi Province, China

Objectives

This research aimed to explore the prevalence and determinants of overweight, obesity, and central obesity in Shenmu City, Shaanxi Province, China and to offer guidance for preventative health measures.

Methods

We conducted a multi-stage, stratified random sampling survey among 4,565 residents of Shenmu City. Data collection included questionnaires and anthropometric assessments to gather socio-demographic data and to identify cases of overweight, obesity, and central obesity. Multivariable logistic regression analysis was utilized to assess the association between various factors and these conditions.

Results

The observed prevalence rates for overweight, obesity, central obesity, and the combination of overweight/obesity with central obesity were 39.9%, 18.2%, 48.0%, 32.8%, and 22.8%, respectively. Notably, the incidence of these conditions was significantly higher in men compared to women. The prevalence of overweight and obesity initially increased and then decreased with age, whereas the prevalence of central obesity consistently rose. Furthermore, a higher educational level correlated with lower prevalence rates. Additionally, our analysis indicated that hypertension, dyslipidemia, and hyperuricemia are risk factors for these conditions.

Conclusions

The findings of this study offer crucial insights for formulating effective strategies to prevent and manage obesity in Shenmu City.

Development of hypertension models for lung cancer screening cohorts using clinical and thoracic aorta imaging factors

This study aims to develop and validate nomogram models utilizing clinical and thoracic aorta imaging factors to assess the risk of hypertension for lung cancer screening cohorts. We included 804 patients and collected baseline clinical data, biochemical indicators, coexisting conditions, and thoracic aorta factors. Patients were randomly divided into a training set (70%) and a validation set (30%). In the training set, variance, t-test/Mann-Whitney U-test and standard least absolute shrinkage and selection operator were used to select thoracic aorta imaging features for constructing the AIScore. Multivariate logistic backward stepwise regression was utilized to analyze the influencing factors of hypertension. Five prediction models (named AIMeasure model, BasicClinical model, TotalClinical model, AIBasicClinical model, AITotalClinical model) were constructed for practical clinical use, tailored to different data scenarios. Additionally, the performance of the models was evaluated using receiver operating characteristic (ROC) curves, calibration curves and decision curve analyses (DCA). The areas under the ROC curve for the five models were 0.73, 0.77, 0.83, 0.78, 0.84 in the training set, and 0.77, 0.78, 0.81, 0.78, 0.82 in the validation set, respectively. Furthermore, the calibration curves and DCAs of both sets performed well on accuracy and clinical practicality. The nomogram models for hypertension risk prediction demonstrate good predictive capability and clinical utility. These models can serve as effective tools for assessing hypertension risk, enabling timely non-pharmacological interventions to preempt or delay the future onset of hypertension.

Temporal-spatial distribution characteristics and associated socioeconomic factors of visiting frequency for rural patients with hypertension in Fujian Province, Southeast China

BACKGROUND

Regular follow-up and medication can effectively reduce the risk of adverse outcomes for patients with hypertension. This study aimed to explore the temporal-spatial distribution characteristics and associated socioeconomic factors of visiting frequency for rural patients with hypertension in Fujian province from 2011 to 2016.

METHODS

The medical records of patients with hypertension were abstracted from the database of New Rural Cooperative Medical Scheme. Geographically and temporally weighted regression model was used to analyze the associations between percentage of patients whose visiting frequency ≥ 4 times within a year and seven socioeconomic factors at the county level.

RESULTS

The visiting rate of rural patients with hypertension was 0.79%, 1.27%, 1.87%, 2.29%, 2.78%, 3.43% over the six-year study period, respectively. The percentage of patients whose visiting frequency ≥ 4 times within a year gradually increased over time and the percentage ranged from 61 to 80% in a half of the counties by 2016. In general, there was positive association between Gross Domestic Product per capita and the percentage of patients whose visiting frequency ≥ 4 times within a year. The percentage of female patients, percentage of patients who aged ≥ 60 years, percentage of low-income patients, carbon emission intensity, percentage of savings and number of health technicians per 10,000 persons were negatively correlated with the percentage of patients whose visiting frequency ≥ 4 times within a year in most of counties of Fujian Province. In the sensitivity analysis, the percentage of outpatients whose visiting frequency ≥ 4 times within a year was higher than that of all patients. There was positive association between percentage of outpatients who aged ≥ 60 years and the percentage of outpatients whose visiting frequency ≥ 4 times.

CONCLUSIONS

The visiting rate and the visiting frequency within a year for rural patients with hypertension in Fujian province need to be improved. Female and elderly patients should be the focus of health management. Effectively implementing the family doctor services, providing several kinds of free antihypertensive drugs, improving energy utilization efficiency and reasonably allocating the health resources may be the effective strategies to improve the follow-up compliance of patients.

Association of the trajectory of plasma aldosterone concentration with the risk of cardiovascular disease in patients with hypertension: a cohort study

The purpose of this study was to determine the long-term pattern of plasma aldosterone concentration (PAC) trajectories and to explore the relationship between PAC trajectory patterns and cardiovascular disease (CVD) risk in patients with hypertension. Participants were surveyed three times between 2010 and 2016, and latent mixed modeling was employed to determine the trajectory of PAC over the exposure period (2010-2016). A Cox regression analysis was used to examine the association between PAC trajectory patterns and the risk of CVD (stroke and myocardial infarction). Hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) were calculated and reported. During a median follow-up of 4.10 (3.37-4.50) years, 82 incident CVD cases (33 myocardial infarction cases and 49 stroke cases) were identified. Among all three PAC models, the high-stability PAC pattern exhibited the highest risk of CVD. After full adjustment for all covariables, HRs were 2.19 (95% CI 1.59-3.01) for the moderate-stable pattern and 2.56 (95% CI 1.68-3.91) for the high-stable pattern in comparison to the low-stable pattern. Subgroup and sensitivity analyses verified this association. The presence of a high-stable PAC trajectory pattern is associated with an elevated risk of CVD in hypertensive patients. Nevertheless, more studies are warranted to confirm these findings.

Trends of mean systolic and diastolic blood pressure among adults in Shenzhen, China, 1997-2018: findings from three rounds of the population-based survey

OBJECTIVE

To quantify the trends in systolic and diastolic blood pressure (BP) among adults in Shenzhen from 1997 to 2018.

DESIGN

Cross-sectional study.

SETTINGS

The data were collected from all districts in Shenzhen, China in the years of 1997, 2009 and 2018 by multistage cluster sampling procedure.

PARTICIPANTS

Participants were residents aged 18-69 years in Shenzhen, China. A total of 26 621 people were included: 8266 people in 1997, 8599 people in 2009 and 9756 people in 2018.

PRIMARY AND SECONDARY OUTCOME MEASURES

All participants were surveyed about their sociodemographic and lifestyle information. BP was measured by trained physicians using a mercury sphygmomanometer. Hypertension was defined as systolic BP of at least 140 mm Hg and diastolic BP of at least 90 mm Hg, self-reported use of antihypertensive medications or both. Hypertension control was defined as systolic BP values of less than 140 mm Hg and diastolic BP values of less than 90 mm Hg.

RESULT

Age-adjusted mean systolic BP increased from 117±16 mm Hg to 123±15 mm Hg (p<0.001) in males, and from 113±18 mm Hg to 115±16 mm Hg (p<0.001) in females from 1997 to 2018. Diastolic BP among males increased from 75 mm Hg (SD=11) to 79 mm Hg (SD=11) and increased from 71 mm Hg (SD=10) to 73 mm Hg (SD=10) among females between 1997 and 2018 (p<0.001). Rate of hypertension rose rapidly from 17.71% (95% CI: 16.60% to 18.90%) in 2009 to 24.01% (95% CI: 22.84% to 25.22%) in 2018 among males (p<0.001), whereas the prevalence among females remained stable at around 13.5% (p=0.98). Both awareness and treatment rates of hypertension among males and females showed a decreased trend between 2009 and 2018, while no significant changes were observed for control rates.

CONCLUSIONS

The mean systolic BP and diastolic BP among adults in Shenzhen increased from 1997 to 2018, and no improvements in hypertension awareness, treatment and control rates were found.

Antihypertensive effect and mechanism of the traditional recipe of medicine food homology (Buyang Huanwu Decoction) in China: Meta analysis and network pharmacological exploration

Background

Hypertension has become a part of the lives of many people worldwide. With the development, an increasing number of people have begun to control their hypertension through products of medicine food homology, such as Buyang Huanwu Decoction (BYHWD). However, there has been no objective review of the regulation of hypertension by BYHWD.

Methods

As of 9 October 2023, this review made a detailed search of nine databases to look for random controlled trials (RCTs) focused on the use of BYHWD for treating hypertension. This was followed by network pharmacological analysis, and molecular docking assessment using AutoDockTools to explore the mode of action.

Results

BYHWD was effective in reducing SBP (MD: 0.767; 95 % CI: 0.629, 0.905; p = 0.000), DBP (MD: 0.427; 95 % CI: 0.292, 0.561; p = 0.000), 24h SBP (MD: 0.665; 95 % CI: 0.368, 0.962; p = 0.000), 24h DBP (MD: 0.547; 95 % CI: 0.318, 0.777; p = 0.000), dSBP (MD: 0.625; 95 % CI: 0.395, 0.855; p = 0.000), dDBP (MD: 0.632; 95 % CI: 0.401, 0.862; p = 0.000), nSBP (MD: 0.859; 95 % CI: 0.340, 1.377; p = 0.001), nDBP (MD: 0.704; 95 % CI: 0.297, 1.112; p = 0.001), pv (MD: 1.311; 95 % CI: 0.363, 2.259; p = 0.007) and NIHSS (MD: 1.149; 95 % CI: 0.100, 2.199; p = 0.032), and elevating CER (OR = 2.848; 95 % CI: 1.388, 5.843; p = 0.004). However, BYHWD did not significantly reduce HCY, and there was no significant difference in the incidence of AE. In terms of the mechanism of action, the main active ingredient of BYHWD is quercetin, and the core targets are AKT1, MMP9, and others. Molecular docking also showed that quercetin mainly interacts with the amino acid residue CYS-28 of MMP2. Second, the KEGG analysis showed that BYHWD mainly act on HIF-1, Apelin, and cGMP-PKG signalling pathways, and GO analysis showed that it related to the apical part of the cell, circulatory system processes, and nuclear receptor activity. Conclusion: BYHWD can lowered blood pressure, reduced plasma viscosity, and restored neurological function with good tolerability, and had no significant effect on HCY levels. This study further demonstrated that quercetin is the main active ingredient of BYHWD that acts via the AKT1 and HIF-1 signalling pathways. These results provide new guidance for people's dietary choices by the general public.

Efficacy and safety of olmesartan medoxomil-amlodipine besylate tablet in Chinese patients with essential hypertension: A prospective, single-arm, multi-center, real-world study

There lacks real-world study with a large sample size assessing olmesartan medoxomil-amlodipine besylate (OM-AML) tablet. Therefore, this study aimed to evaluate the efficacy and safety of OM-AML tablet in patients with essential hypertension. Totally, 1341 patients from 36 medical centers with essential hypertension who took OM-AML (20/5 mg) tablet were analyzed in the current prospective, single-arm, multi-center, real-world study (SVK study). Seated systolic blood pressure (SeSBP) and seated diastolic blood pressure (SeDBP) at baseline, week (W)4 and W8 were measured. The mean (±SE) change of SeSBP/SeDBP was -10.8 ± 0.4/-6.6 ± 0.3 mmHg at W4 and -12.7 ± 0.5/-7.6 ± 0.3 mmHg at W8, respectively. At W4, 78.8% and 29.0% patients achieved BP target by China and American Heart Association (AHA) criteria; at W8, 84.7% and 36.5% patients reached blood pressure (BP) target by China and AHA criteria, accordingly. Meanwhile, 80.2% and 86.4% patients achieved BP response at W4 and W8, respectively. Home-measured SeSBP and SeDBP decreased from W1 to W8 (both p < .001). Besides, patients' and physicians' satisfaction were elevated at W8 compared with W0 (both p < .001). The medication possession rate was 94.8% from baseline to W4 and 91.3% from baseline to W8. The most common drug-related adverse events were nervous system disorders (4.6%), vascular disorders (2.6%), and general disorders and administration site conditions (2.3%) by system organ class, which were generally mild and manageable. In conclusion, OM-AML tablet is one of the best antihypertensive agents in patients with essential hypertension.

Changing Patterns of Stroke and Subtypes Attributable to High Systolic Blood Pressure in China From 1990 to 2019

BACKGROUND

It is unknown whether high systolic blood pressure had a similar effect on the disease burden of stroke subtypes. The aim of our study is to compare the long-term trends of stroke subtypes and sex groups attributable to high systolic blood pressure in China from 1990 to 2019.

METHODS

Data about the age-standardized mortality rate and the age-standardized disability-adjusted life-year rate of stroke subtypes attributable to high systolic blood pressure in China were extracted in GBD (Global Burden of Disease) 2019. The trends in the age-standardized mortality rate and the age-standardized disability-adjusted life-year rate were calculated using the liner regression and age-period-cohort method, adjusted for age, period, and cohort.

RESULTS

The estimated annual percentage change for mortality of stroke attributable to high systolic blood pressure was different from subtypes, with an estimated annual percentage change and 95% CI of 0.56 (0.37-0.74) for ischemic stroke (IS), -1.52 (-1.97 to -1.07) for intracerebral hemorrhage, and -7.02 (-7.86 to -6.17) for subarachnoid hemorrhage (SAH). The curve of the net drifts showed a downward trend for intracerebral hemorrhage and SAH, but that showed a stable trend for IS. The curve of local drifts showed a slow upward trend with age for IS, a slow downward trend for intracerebral hemorrhage, and a sharp downward trend for SAH. The drift curves showed different trends for males and females. The proportion of stroke mortality in young males was gradually increasing. The cohort rate ratio varied by subtypes, with the greatest decline for SAH, a slight decrease for intracerebral hemorrhage, and a slight increase for IS. The period rate ratio had decreased over the past 3 decades, with the greatest decline for SAH and the weakest decrease for IS. Moreover, both the period and cohort rate ratios for IS mortality due to high systolic blood pressure in males have increased significantly over the past 3 decades.

CONCLUSIONS

Our results provided strong evidence that the disease burden of stroke attributable to high systolic blood pressure varied by subtypes and sex in China from 1990 to 2019. The age-standardized mortality rate and the age-standardized disability-adjusted life-year rate decreased for hemorrhagic stroke but increased for IS. Males had a higher mortality and exposure risk but a slighter decreasing trend than females. Our study suggested that greater attention should be given to the prevention of the burden of IS attributable to systolic blood pressure in China, especially for males.

Calcitriol reverses age-related hypertension via downregulating renal AP1/AT1R pathway through regulating mitochondrial function

BACKGROUND

The vitamin D level in the blood is associated with the incidence of hypertension. The present study investigated whether or not calcitriol, an active form of vitamin D, reverses age-related hypertension.

METHODS

Young (3-month-old) and aged (12-month-old) C57BL/6 male mice were administered with or without calcitriol at 150 ng/kg per day by oral gavage for 8 weeks. Blood pressure was measured by tail-cuff plethysmography and telemetry, and superoxide production in renal tissue was assessed by fluorescence imaging, and the protein expression of AP1/AT1R signaling pathway was examined by Western blot.

RESULTS

We showed that 24-hour renal sodium excretion was impaired and blood pressure was increased in aged mice, which was related to the enhancement of renal AT1R expression and function. In addition, the expression of transcription factor AP1 (a dimer of c-Fos and c-Jun) and the binding of AP1 to the AT1R promoter region was significantly enhanced, accompanied by decreased nuclear translocation of Nrf2, abnormal mitochondrial function including decreased ATP production, NAD+/NADH ratio and mtDNA copy numbers, and increased reactive oxygen species. Calcitriol increased 24-hour urinary sodium excretion and reduced blood pressure in aged mice. Mechanically, calcitriol increased the nuclear translocation of Nrf2, improved mitochondrial function, reduced AP1 binding ability to AT1R promoter, which reversed enhanced AT1R expression and function, and lowered blood pressure in aged mice.

CONCLUSIONS

Our findings indicated that calcitriol reversed age-related hypertension via downregulating renal AP1/AT1R pathway through regulating mitochondrial function. Thus, calcitriol may be a valuable therapeutic strategy for age-related hypertension.

Hypertension, socioeconomic status and depressive and anxiety disorders: a cross-sectional study of middle-aged and older Chinese women

OBJECTIVES

To investigate the association of hypertension with depressive and anxiety disorders in middle-aged and older Chinese women, and to further assess whether the association was influenced by socioeconomic status (SES).

DESIGN

Nationwide cross-sectional study.

SETTING

Six provinces of the eastern, central and western regions of China.

PARTICIPANTS

Women aged 40-70 years were included by a multistage stratified random cluster sampling in 2018 (N=9900).

PRIMARY OUTCOME MEASURES

Depressive and anxiety disorders were measured by the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7, respectively. Logistic regression models were used to evaluate the OR and 95% CI for hypertension and the odds of depressive and anxiety disorders.

RESULTS

18.5% of participants reported having hypertension; 20.9% and 15.3% of women experienced depressive and anxiety disorders, respectively. After adjusting for potential confounders, women diagnosed with hypertension were more likely to have depressive (OR=1.27, 95% CI 1.11 to 1.45) and anxiety disorders (OR=1.48, 95% CI 1.28 to 1.71) than those without hypertension. Stratified analyses demonstrated that hypertension was significantly associated with higher odds of depressive disorders in women living in rural areas (OR=1.34, 95% CI 1.13 to 1.59), with lower levels of education (OR=1.28, 95% CI 1.12 to 1.46) and with average monthly household income <¥3000 (OR=1.33, 95% CI 1.12 to 1.59), while hypertension was significantly correlated with increased odds of anxiety disorders in women living in urban (OR=1.41, 95% CI 1.12 to 1.79) and rural areas (OR=1.53, 95% CI 1.27 to 1.84), with lower levels of education (OR=1.47, 95% CI 1.27 to 1.70), and with average monthly household income <¥3000 (OR=1.45, 95% CI 1.20 to 1.75) and ≥¥3000 (OR=1.49, 95% CI 1.18 to 1.86).

CONCLUSIONS

Hypertension was associated with increased odds of depressive and anxiety disorders among middle-aged and older women, especially in those with low SES. Effective strategies and actions for identification and management of hypertension and depressive and anxiety disorders are needed.

Effect and prediction of physical exercise and diet on blood pressure control in patients with hypertension

The study aims to explore the current status of hypertension control and its predictors in patients with hypertension in China and provide evidence for preventing and controlling hypertension. A questionnaire survey was conducted among 300 hypertensive patients who visited the Second Affiliated Hospital of Anhui Medical University from February 20, 2023 to March 11, 2023. The patients were divided into a well-controlled group and an untargeted-control group according to their hypertension control status. A total of 294 subjects, including 83 in the well-controlled group and 211 in the untargeted-control group, were included in the analysis. Multivariate logistic regression analysis showed that hypertensive patients with high BMI and family history of hypertension were risk factors for hypertension control. Married status was a protective factor for hypertension control. SVM optimized the model with γ = 0.001 and a penalty factor of C = 0.001. The prediction accuracy of the final model was 80.9%. The findings indicated that BMI, family history of hypertension, and marital status were independent predictors of blood pressure control. Further studies are warranted to illustrate potential mechanisms for improving hypertensive patients' blood pressure control.

Hypertension doctors' awareness and practice of medication adherence in hypertensive patients: a questionnaire-based survey

Background

Poor adherence to antihypertensive drugs is a major cause of unsatisfactory blood pressure control. Hypertension doctors play an integral role in improving medication adherence in hypertensive patients. Although most existing studies have recognized the status quo and influencing factors of medication adherence, little attention has been paid to hypertension doctors' awareness and practice in hypertension management. Therefore, in this study, we aimed to investigate hypertension doctors' awareness and practice of medication adherence in hypertensive patients.

Methods

This is a cross-sectional survey. A self-reported questionnaire was developed and sent to hypertension doctors in Hunan province, China, between May 1, 2022 and July 1, 2022. Univariate and generalized linear models were used to identify the factors influencing hypertension doctors' awareness and practice. The correlation between awareness and practice was determined using Spearman's correlation coefficient.

Results

In total, 236 valid questionnaires were collected (valid response rate, 73.5%). Of the respondents, 44.1% were chief physicians and 64.4% were females. Approximately half of the respondents were ≥40 years old and had over 14 years of working experience. Most respondents (87.7%) did not have hypertension, but 54.2% had a family history of hypertension. The average awareness and practice scores were 29.8 ± 8.8 and 39.4 ± 7.1, respectively, out of 50, with higher scores indicating higher levels of awareness or practice. More hypertension consultations and more antihypertensive prescriptions issued were associated with better awareness and practice among respondents (ps < 0.05). Respondents with higher education and professional titles had higher awareness (ps < 0.05). Moreover, respondents with 6-13 years of work experience had better practice than those with <5 years of work experience (p = 0.017). There was a significant correlation between hypertension doctors' awareness and practice of medication adherence in hypertensive patients (R = 0.682, p < 0.001). These findings indicate that misconceptions persist in hypertension doctors' awareness and practice of patient medication adherence.

Conclusion

Hypertension doctors lack sufficient and correct awareness and practice of medication adherence in hypertensive patients.

E2/E3 and E3/E4 Genotypes of the Apolipoprotein E are Associated with Higher Risk of Diabetes Mellitus in Patients with Hypertension

Objective

Apolipoprotein E (APOE) plays an important role in the lipid metabolism. APOE polymorphisms have been implicated in susceptibility to diabetes mellitus (DM). However, the association between APOE polymorphisms and the risk of DM among the hypertensive patients remains unclear. Our study aimed to evaluate this relationship to provide clues for further developing DM in hypertensive patients.

Methods

The study included 808 hypertensive patients with DM and 1226 hypertensive patients without DM as controls. The APOE 388T>C (rs429358) and 526C>T (rs7412) polymorphisms were genotyped by polymerase chain reaction (PCR) - microarray. Differences in APOE genotypes between subjects and controls were compared. To analyze the relationship between APOE genotypes and DM risk, multiple logistic regression analysis was performed after adjusting for gender, age, smoking history, and drinking history.

Results

The APOE E2/E4, E3/E3 genotype and ε2, ε3 allele frequency had significant difference between DM patients and controls (P<0.05). The DM patients with ɛ4 allele had lower level in high-density lipoprotein cholesterol (HDL-C) and higher level in apolipoprotein B (ApoB) than those with ɛ2 allele. The results of logistic regression analysis indicated that the APOE genotype of E2/E3 with adjusted OR=1.350 (95% Cl=1.009-1.806, P=0.043) and E3/E4 with adjusted OR=1.325 (95% Cl=1.034-1699, P=0.026) may be independent risk factors for DM.

Conclusion

APOE E2/E3 and E3/E4 genotypes may be risk factors for developing diabetes mellitus in hypertensive patients.

Long-term exposure to ambient ozone at workplace is positively and non-linearly associated with incident hypertension and blood pressure: longitudinal evidence from the Beijing-Tianjin-Hebei medical examination cohort

BACKGROUND

There is limited longitudinal evidence on the hypertensive effects of long-term exposure to ambient O3. We investigated the association between long-term O3 exposure at workplace and incident hypertension, diastolic blood pressure (DBP), systolic blood pressure (SBP), pulse pressure (PP), and mean arterial pressure (MAP) in general working adults.

METHODS

We conducted a cohort study by recruiting over 30,000 medical examination attendees through multistage stratified cluster sampling. Participants completed a standard questionnaire and comprehensive medical examination. Three-year ambient O3 concentrations at each employed participant's workplace were estimated using a two-stage machine learning model. Mixed-effects Cox proportional hazards models and linear mixed-effects models were used to examine the effect of O3 concentrations on incident hypertension and blood pressure parameters, respectively. Generalized additive mixed models were used to explore non-linear concentration-response relationships.

RESULTS

A total of 16,630 hypertension-free working participants at baseline finished the follow-up. The mean (SD) O3 exposure was 45.26 (2.70) ppb. The cumulative incidence of hypertension was 7.11 (95% CI: 6.76, 7.47) per 100 person-years. Long-term O3 exposure was independently, positively and non-linearly associated with incident hypertension (Hazard ratios (95% CI) for Q2, Q3, and Q4 were 1.77 (1.34, 2.36), 2.06 (1.42, 3.00) and 3.43 (2.46, 4.79), respectively, as compared with the first quartile (Q1)), DBP (β (95% CI) was 0.65 (0.01, 1.30) for Q2, as compared to Q1), SBP (β (95% CI) was 2.88 (2.00, 3.77), 2.49 (1.36, 3.61) and 2.61 (1.64, 3.58) for Q2, Q3, and Q4, respectively), PP (β (95% CI) was 2.12 (1.36, 2.87), 2.03 (1.18, 2.87) and 2.14 (1.38, 2.90) for Q2, Q3, and Q4, respectively), and MAP (β (95% CI) was 1.39 (0.76, 2.02), 1.04 (0.24, 1.84) and 1.12 (0.43, 1.82) for Q2, Q3, and Q4, respectively). The associations were robust across sex, age, BMI, and when considering PM2.5 and NO2.

CONCLUSIONS

To our knowledge, this is the first cohort study in the general population that demonstrates the non-linear hypertensive effects of long-term O3 exposure. The findings are particularly relevant for policymakers and researchers involved in ambient pollution and public health, supporting the integration of reduction of ambient O3 into public health interventions.

Longitudinal study of dietary patterns and hypertension in adults: China Health and Nutrition Survey 1991-2018

China is undergoing the nutrition transition that may explain partly the high prevalence of hypertension. We aimed to investigate the longitudinal association between dietary patterns and hypertension in Chinese adults over 28 years of follow-up. We used data collected in the China Health and Nutrition Survey from 1991 to 2018. Adults aged 18 years and above (n = 15,929) were included in the analysis, for whom questionnaires and anthropometric data were collected during at least two waves. Factor analysis was conducted to derive food patterns based on 18 foods or food groups. We constructed three-level mixed-effect linear regression models to estimate systolic blood pressure (SBP) and diastolic blood pressure (DBP) in relation to quartiles of dietary pattern score and performed three-level mixed-effect logistic regression models to assess the risk of hypertension. Participants in the top quartile of the modern pattern had a decrease in SBP (β = - 0.51; 95% CI -0.86, -0.16; P < 0.01) when adjusted for all potential confounders, whereas participants in the top quartile of the meat pattern had an increase in DBP (β = 0.31; 95% CI 0.08, 0.53; P < 0.01). Participants in the highest quartile of the meat pattern were more likely to have hypertension (OR = 1.14; 95% CI 1.03, 1.24; P < 0.01). Adherence to the modern pattern characterized by high intake of fruits and dairy products was inversely associated with SBP, whereas the meat pattern was positively associated with DBP and the risk of hypertension. These findings may well have important public health implications.

The relationship between perfluoroalkyl substances and hypertension: A systematic review and meta-analysis

Hypertension is an important risk factor for cardiovascular diseases (CVDs) and a leading cause of premature death. Epidemiological studies have found that perfluoroalkyl substances (PFASs) are associated with hypertension. However, the correlation between PFASs and hypertension has not been systematically reported. Based on evidence from population epidemiological surveys, we conducted a meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to assess the correlation between PFASs exposure and hypertension. In this study, three databases of PubMed, Web of science, Embase were searched and 13 literatures with 81,096 participants were included. Literature heterogeneity was evaluated by I² statistic, and the random effect model (I² > 50%) and fixed effect model (I² < 50%) were used to combine the studies in meta-analysis. The results showed that PFNA (OR = 1.11, 95% CI: 1.04-1.19), PFOA (OR = 1.12, 95% CI: 1.02-1.23), PFOS (OR = 1.19, 95% CI: 1.06-1.34) and PFHxS (OR = 1.03, 95% CI: 1.00-1.06) were significantly associated with hypertension, while other types of PFASs (∑PFAS, PFDA, PFUnDA) had no statistical significance. In addition, PFNA (OR = 1.12, 95% CI: 1.03-1.22), PFOA (OR = 1.12, 95% CI: 1.01-1.25) and PFOS (OR = 1.12, 95% CI: 1.00-1.25) exposure were positively correlated with the risk of hypertension in men, but not in women. Our study reveals that PFASs are risk factors for hypertension, with notable gender differences observed in PFASs-exposed populations. Specifically, males exposed to PFNA, PFOA, and PFOS exhibit a higher risk of hypertension compared to females. However, further investigations are needed to delve into the precise mechanism through which PFASs contribute to the development of hypertension.

Consumption frequencies of beverages and the hypertension risk in adults: a cohort study in China

OBJECTIVE

To explore the associations between the consumption frequencies of alcohol, tea and sugar-sweetened beverages (SSBs) and the hypertension risk among Chinese adults.

DESIGN

A longitudinal study of the effect of beverage consumption on hypertension risk.

SETTING

Nine provinces in China, including Jiangsu, Hubei, Hunan, Guangxi, Guizhou, Liaoning, Heilongjiang, Shandong and Henan.

PARTICIPANTS

The longitudinal data of the China Health and Nutrition Survey from 2004 to 2015 were used. A total of 4427 participants from 9 provinces were included at baseline.

OUTCOME

First incidence of hypertension.

RESULTS

During a mean follow-up of 8.7 years, 1478 participants developed hypertension. Alcohol consumption more than twice a week in young men (HR 1.86, 95% CI 1.09 to 3.18) or middle-aged men (HR 1.37, 95% CI 1.01 to 1.87) was associated with a higher hypertension risk. Middle-aged women who consumed tea frequently (HR 0.71, 95% CI 0.52 to 0.97), or young women who consumed SSBs less than once a week (HR 0.31, 95% CI 0.14 to 0.67) had a lower risk of hypertension.

CONCLUSIONS

High-frequency alcohol consumption increased the risk of hypertension in men, and frequent tea consumption and low-frequency SSBs consumption were associated with lower risk of hypertension in women. Consumption frequency of beverages was also suggested to be considered in the prevention and control of hypertension.

The Combined Effect of Elevated Blood Pressure and Occupational Noise Exposure on Bilateral High-Frequency Hearing Loss: Evidence From a Large Sample Cross-sectional Study

BACKGROUND

Combined effect of elevated blood pressure and occupational noise exposure on hearing loss have rarely been evaluated among Chinese population.

METHODS

This cross-sectional study was conducted in 242,811 participants. Logistic regression model was performed to estimate the independent and combined associations.

RESULTS

Compared with participants without occupational noise exposure, the risk of bilateral high-frequency hearing loss (BHFHL) was significantly higher for noise exposure 10 years or more (odds ratio [OR] = 1.29, 95% confidence interval [95% CI] = 1.23-1.35). Compared with no hypertension, participants with grade 1 hypertension had higher risk of BHFHL in all age groups (OR, 1.14; 95% CI, 1.09-1.20). As to the combined effect, the highest BHFHL risk was found in males (OR, 1.51; 95% CI, 1.37-1.67), especially among participants with grade 1 hypertension older than 50 years (OR, 1.65; 95% CI, 1.46-1.88).

CONCLUSIONS

Elevated blood pressure may synergistically influence hearing loss combined with occupational noise exposure.

Obesity-and lipid-related indices as a predictor of hypertension in Mid-aged and Elderly Chinese: A Cross-sectional Study

Objective

Middle-aged and elderly people in China probably suffer from hypertension. There is a close relationship between obesity-and lipid-related index and hypertension, which is recognized by recent studies. However, these studies have not systematically compared the relationship between the two. We aim to find the most effective obesity-and lipid-related index for predicting hypertension.

Method

A total of 9488 middle-aged and elderly people in China participated in this study. In this study, the subjects were divided into male and female groups by the definition of the 2018 Chinese Guidelines for Prevention and Treatment of Hypertension. Searching for the best predictors among 13 obesity-and lipid-related indicators through binary logistic regression analyses and receiver operator curve (ROC). These 13 indicators are body mass index (BMI), waist circumference (WC), waist-height ratio (WHtR), conicity index (CI), visceral adiposity index (VAI), Chinese visceral adiposity index (CVAI), lipid accumulation product (LAP), a body shape index (ABSI), body roundness index (BRI), triglyceride glucose index (TyG-index) and its correlation index (TyG-BMI, TyG-WC, TyG-WHtR).

Results

After adjusting bias, all 13 indexes are risk factors for hypertension. In ROC curve analysis, thirteen obesity-and lipid-related factors can predict the occurrence of hypertension. Among them, CVAI has the best prediction effect (male: AUC = 0.660, female: AUC = 0.699). AUC for WHtR was equal to that for BRI and TyG - WHtR in identifying hypertension in male. Similarly, AUC of TyG-BMI and BMI were the same. In females, AUC for WHtR and BRI were the same when predicting hypertension. AUC of ABSI was much lower than other test indexes.

Conclusion

In predicting hypertension, thirteen obesity-and lipid-related factors are effective. In addition, in males and females, CVAI is the best indicator to indicate hypertension. TyG-WHtR, WHtR, and BRI performed well in predicting metabolic syndrome in both males and females. ABSI has a poor ability to predict hypertension.

Two Novel Angiotensin I-Converting Enzyme (ACE) Inhibitory Peptides from Rice (Oryza sativa L.) Bran Protein

To realize the high-value utilization of rice byproducts, the rice bran protein hydrolysate was separated and purified by ultrafiltration and reversed-phase high-performance liquid chromatography (RP-HPLC), then the sequences of peptides were identified by liquid chromatography with tandem mass spectrometry (LC-MS/MS), and their molecular docking analysis and activities in vitro and in the cell were carried out. Two novel peptides FDGSPVGY (840.3654 Da) and VFDGVLRPGQ (1086.582 Da) were obtained with IC₅₀ values of 0.079 mg/mL (94.05 μM) and 0.093 mg/mL (85.59 μM) on angiotensin I-converting enzyme (ACE) inhibitory activity in vitro, respectively. Molecular docking results showed that two peptides interacted with ACE receptor protein through hydrogen bonding, hydrophobic interactions, etc. Through the EA.hy926 cells, it was found that FDGSPVGY and VFDGVLRPGQ could promote the release of nitric oxide (NO) and reduce the content of ET-1 to achieve the effect of antihypertension. In conclusion, the peptides from rice bran protein exhibited significant antihypertension activity and may be expected to realize the high-value utilization of rice byproducts.

Hypertension control rate in India: systematic review and meta-analysis of population-level non-interventional studies, 2001-2022

Background

Hypertension is a significant contributor to mortality in India. Achieving better hypertension control rate at the population level is critical in reducing cardiovascular morbidity and mortality.

Methods

Hypertension control rate was defined as the proportion of patients with their blood pressure under control (systolic blood pressure <140 mmHg and diastolic blood pressure <90 mmHg). We conducted a systematic review and meta-analysis of community-based, non-interventional studies published after 2001 that reported hypertension control rates. We searched PubMed, Embase, and Web of Science databases, and grey literature, and extracted data using a common framework, and summarized the study characteristics. We conducted random-effects meta-analysis using untransformed hypertension control rates and reported the overall summary estimates and subgroup estimates of control rates as percentages and 95% confidence intervals. We also conducted mixed-effects meta-regression with sex, region, and study period as covariates. The risk of bias was assessed, and level of evidence was summarized using SIGN-50 methodology. The protocol was pre-registered with PROSPERO, CRD42021267973.

Findings

The systematic review included 51 studies (n = 338,313 hypertensive patients). 21 studies (41%) reported poorer control rates among males than females, and six studies (12%) reported poorer control rates among rural patients. The pooled hypertension control rate in India during 2001-2020 was 17.5% (95% CI: 14.3%-20.6%)-with significant increase over the years, reaching 22.5% (CI: 16.9-28.0%) in 2016-2020. Sub-group analysis showed significantly better control rates in the South and West regions, and significantly poorer control rates among males. Very few studies reported data on social determinants or lifestyle risk factors.

Interpretation

Less than one-fourth of hypertensive patients in India had their blood pressure under control during 2016-2020. Although the control rate has improved compared to previous years, substantial differences exist across regions. Very few studies have examined the lifestyle risk factors and social determinants relevant to hypertension control in India. The country needs to develop and evaluate sustainable, community-based strategies and programs to improve hypertension control rates.

Associations of the Triglyceride and Glucose Index With Hypertension Stages, Phenotypes, and Their Progressions Among Middle-Aged and Older Chinese

Objectives: To assess the associations of the triglyceride and glucose (TyG) index with hypertension stages, phenotypes, and their progressions. Methods: The data originated from the China Health and Retirement Longitudinal Study. Multinomial logistic regression investigated the associations of the TyG index with hypertension stages (stage 1, stage 2), phenotypes (isolated systolic hypertension [ISH], isolated diastolic hypertension [IDH], systolic diastolic hypertension [SDH]), their progressions. Results: Compared with the lowest quartile of TyG index, the highest quartile was associated with increased risks of stage 1 hypertension (OR 1.71, 95% CI 1.38-2.13), stage 2 (1.74, 1.27-2.38), ISH (1.66, 1.31-2.11), IDH (2.52, 1.26-5.05), and SDH (1.65, 1.23-2.23). Similar results were found when TyG index was a continuous variable. From 2011 to 2015, a higher baseline TyG index was associated with normotension to stage 1 (per-unit: 1.39, 1.16-1.65), normotension to ISH (per-unit: 1.28, 1.04-1.56), and normotension to IDH (per-unit: 1.94, 1.27-2.97). Conclusion: The TyG index was associated with different hypertension stages, phenotypes, their progressions, and could be served as a surrogate indicator for early hypertension management.

Development of therapeutic vaccines for the treatment of diseases

Vaccines are one of the most effective medical interventions to combat newly emerging and re-emerging diseases. Prophylactic vaccines against rabies, measles, etc., have excellent effectiveness in preventing viral infection and associated diseases. However, the host immune response is unable to inhibit virus replication or eradicate established diseases in most infected people. Therapeutic vaccines, expressing specific endogenous or exogenous antigens, mainly induce or boost cell-mediated immunity via provoking cytotoxic T cells or elicit humoral immunity via activating B cells to produce specific antibodies. The ultimate aim of a therapeutic vaccine is to reshape the host immunity for eradicating a disease and establishing lasting memory. Therefore, therapeutic vaccines have been developed for the treatment of some infectious diseases and chronic noncommunicable diseases. Various technological strategies have been implemented for the development of therapeutic vaccines, including molecular-based vaccines (peptide/protein, DNA and mRNA vaccines), vector-based vaccines (bacterial vector vaccines, viral vector vaccines and yeast-based vaccines) and cell-based vaccines (dendritic cell vaccines and genetically modified cell vaccines) as well as combinatorial approaches. This review mainly summarizes therapeutic vaccine-induced immunity and describes the development and status of multiple types of therapeutic vaccines against infectious diseases, such as those caused by HPV, HBV, HIV, HCV, and SARS-CoV-2, and chronic noncommunicable diseases, including cancer, hypertension, Alzheimer's disease, amyotrophic lateral sclerosis, diabetes, and dyslipidemia, that have been evaluated in recent preclinical and clinical studies.

The design and implementation of natural population cohort study Biobank: A multiple-center project cooperation with medical consortia in Southwest China

Objective

The West China Hospital of Sichuan University collaborated with regional medical consortia in Sichuan Province to launch a natural population cohort study (NPCS) to investigate the health status of residents and collect public health data in southwest China.

Methods

Up to 80,000 participants will be enrolled by the NPCS from 11 regional medical consortia over five years. Individuals are invited to visit one of 11 participating medical consortia to fill out questionnaires, receive a free health exam, and donate biospecimens upon enrolment. All participating medical facilities adhered to standard operating procedures for collecting and processing biospecimens to ensure uniformity (serum, lithium heparinized plasma, ethylene diamine tetraacetie acid plasma, and buffy coat). The Electronic Data Capture System, Picture Archiving and Communication System, Laboratory Information Management System, Biospecimen Quality Control System, Biobank Information Management System, and will be used to sort and classify clinical indices, imaging data, laboratory parameters, pre-analytical variables, and biospecimen information, respectively. All quality assurance and quality control procedures in the NPCS biobank adhered to the "DAIDS Guidelines for Good Clinical Laboratory Practice Standards". This project will integrate high-dimensional multi-omics data, laboratory data, clinical data, questionnaire data, and environmental risk factors.

Results

An estimated 2,240,000 aliquots of the sample will be stored by the end of the study. These samples are linked with comprehensively collected clinical indices, imaging data, and laboratory parameters. Big data analysis can be implemented to create predictive algorithms, explore pathogenesis mechanisms, uncover potential biomarkers, and provide information on public health.

Conclusions

NPCS will provide an integrative approach to research risk factors and pathogenesis of major chronic or endemic diseases in Sichuan Province and provide key scientific evidence to support the formulation of health management policies in China.

Ultra-Processed Food Consumption Associated with Incident Hypertension among Chinese Adults-Results from China Health and Nutrition Survey 1997-2015

Objective: Ultra-processed food (UPF) has been shown to increase the cardiometabolic health risks. We aimed to determine the association between UPF intake based on the NOVA classification and the risk of hypertension incidence during 1997−2015. Methods: Data from 15,054 adults aged ≥ 20 years (47.4% males) attending the China Nutrition and Health Survey (CNHS) were used. Food intake at each survey was assessed by a 3-day 24 h dietary recall and weighed food record method between 1997−2011. Cox regression was used to assess the association between UPF intake and incident hypertension. Results: During a mean average of 9.5 years (SD 5.5) of follow up, 4329 hypertension incident cases were identified. The incident rates (per 1000) for non-consumers and 1−49, 50−99, and ≥100 g/day of UPF intake were 29.5 and 29.5, 33.4, and 36.3, respectively. Compared with non-consumers, the hazard ratios (95% CI) for UPF intake of 1−49, 50−99, and >100 g/day were 1.00 (0.90−1.12), 1.17 (1.04−1.33), and 1.20 (1.06−1.35), respectively, (p = 0.001) after adjusting for potential confounding factors. There was a significant interaction between UPF intake and age with a higher risk in the younger group (<40 years) than in the older one. Conclusion: UPF consumption was dose-responsively associated with increased risk of hypertension among Chinese adults, especially in younger groups.

Short-term exposure to ambient air pollution and readmissions for heart failure among 3660 post-discharge patients with hypertension in older Chinese adults

BACKGROUND

Despite ambient air pollution being associated with various adverse cardiovascular outcomes, the acute effects of ambient air pollution on hospital readmissions for heart failure (HF) among post-discharge patients with hypertension remain less understood.

METHODS

We conducted a time-stratified case-crossover study among 3660 subjects 60 years or older who were admitted to hospital for HF after discharge for hypertension in Guangzhou, China during 2016-2019. For each subject, individualised residential exposures to ambient particulate matter with an aerodynamic diameter ≤1 µm (PM₁), ≤2.5 µm (PM_2.5), ≤10 µm (PM₁₀), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO) and ozone were extracted from our validated grid dataset.

RESULTS

An IQR increase of lag 04-day exposure to PM₁ (IQR: 11.6 μg/m³), PM_2.5 (IQR 21.9 μg/m³), PM₁₀ (IQR 35.0 μg/m³), SO₂ (IQR 4.4 μg/m³), NO₂ (IQR 23.3 μg/m³) and CO (IQR 0.25 mg/m³) was significantly associated with a 9.77% (95% CI 2.21% to 17.89%), 8.74% (95% CI 1.05% to 17.00%), 13.93% (95% CI 5.36% to 23.20%), 10.81% (95% CI 1.82% to 20.60%), 14.97% (95% CI 8.05% to 22.34%) and 7.37% (95% CI 0.98% to 14.16%) increase in odds of HF readmissions, respectively. With adjustment for other pollutants, the association for NO₂ exposure remained stable, while the associations for PM₁, PM_2.5, PM₁₀, SO₂ and CO exposures became insignificant. Overall, an estimated 19.86% of HF readmissions were attributable to NO₂ exposure, while reducing NO₂ exposure to the WHO and China air quality standards would avoid 12.87% and 0.54% of readmissions, respectively. No susceptible populations were observed by sex, age or season.

CONCLUSION

Short-term exposure to ambient NO₂ was significantly associated with an increased odds of HF readmissions among post-discharge patients with hypertension in older Chinese adults.

Dietary Patterns in Association With Hypertension: A Community-Based Study in Eastern China

Objective

This study aimed to explore the association between dietary patterns and hypertension based on a community–based survey in Suzhou, Eastern China.

Methods

This cross–sectional analysis was undertaken from the subset of the Suzhou Food Consumption and Health State Survey in 2018–2019. Adults aged ≥ 18 years were invited to participate in this survey. Dietary intake was collected by a 24–h dietary recall and a weighing method over three consecutive days (including two weekdays and one weekend day). Dietary patterns were defined using factor analysis. Association between the dietary patterns and hypertension was examined by multivariable logistic regression models with adjustment for covariates. Moreover, sensitivity analysis was used to reinforce our findings.

Results

A total of 2,718 participants were included in the final analysis. Rice-vegetable pattern, fast food pattern, fruit-dairy pattern, and wheat-meat pattern were identified. We observed that the fruit-dairy pattern was inversely associated with hypertension after adjustment for all the covariates (OR = 0.55; 95% CI: 0.40, 0.75; P = 0.002). The association between the wheat-meat pattern and hypertension was attenuated and became statistically nonsignificant in sensitivity analyses. The other two patterns were not significantly associated with hypertension (P &gt; 0.05).

Conclusion

The fruit-dairy pattern was inversely associated with the risk of hypertension among Chinese adults. Our findings further emphasize the important role of optimal diet combination in the prevention of hypertension.

Integrating functional data analysis with case-based reasoning for hypertension prognosis and diagnosis based on real-world electronic health records

BACKGROUND

Hypertension is the fifth chronic disease causing death worldwide. The early prognosis and diagnosis are critical in the hypertension care process. Inspired by human philosophy, CBR is an empirical knowledge reasoning method for early detection and intervention of hypertension by only reusing electronic health records. However, the traditional similarity calculation method often ignores the internal characteristics and potential information of medical examination data.

METHODS

In this paper, we first calculate the weights of input attributes by a random forest algorithm. Then, the risk value of hypertension from each medical examination can be evaluated according to the input data and the attribute weights. By fitting the risk values into a risk curve of hypertension, we calculate the similarity between different community residents, and obtain the most similar case according to the similarity. Finally, the diagnosis and treatment protocol of the new case can be given.

RESULTS

The experiment data comes from the medical examination of Tianqiao Community (Tongling City, Anhui Province, China) from 2012 to 2021. It contains 4143 community residents and 43,676 medical examination records. We first discuss the effect of the influence factor and the decay factor on similarity calculation. Then we evaluate the performance of the proposed FDA-CBR algorithm against the GRA-CBR algorithm and the CS-CBR algorithm. The experimental results demonstrate that the proposed algorithm is highly efficient and accurate.

CONCLUSIONS

The experiment results show that the proposed FDA-CBR algorithm can effectively describe the variation tendency of the risk value and always find the most similar case. The accuracy of FDA-CBR algorithm is higher than GRA-CBR algorithm and CS-CBR algorithm, increasing by 9.94 and 16.41%, respectively.

High-normal blood pressure (prehypertension) is associated with PM2.5 exposure in young adults

We aimed to examine PM_2.5 exposure, blood pressure (SBP and DBP) measurement, and hypertension risk factors and to assess the association between PM_2.5 exposure and hypertension among young adults. The mean SBP was 117.78 mmHg, with 11.22% high-normal blood pressure (prehypertension) and 2.51% hypertension (≥ 140 mmHg). DBP was 75.48 mmHg with 26.37% prehypertension and 4.53% hypertension (≥ 90 mmHg). The median PM_2.5 in the past year was 31.79 μg/m³, with highest in winter (49.33 μg/m³), followed by spring (37.34 μg/m³), autumn (29.64 μg/m³), and summer (24.33 μg/m³). Blood pressure was positively correlated with age, height, weight, BMI, daily smoking, alcohol consumption, mental stress, and staying up in the past 1 year, and negatively with season-specific temperature. After adjustment for the covariates, each 10 μg/m³ increase in PM_2.5 was associated with SBP (day 1 = 1.07 mmHg, day 3 = 1.25 mmHg, day 5 = 1.01 mmHg) and DBP (day 1 = 1.06 mmHg, day 3 = 1.28 mmHg, day 5 = 1.29 mmHg, day 15 = 0.87 mmHg, day 30 = 0.56 mmHg). Exposure in winter and the past year was associated with 1.21 mmHg and 0.95 increase mmHg in SBP, respectively. Logistic models showed for every 1 μg/m³ increase of PM_2.5, SBP in day 1 and day 5 was increased by 6% and 4%, and DPB by 3% and 16%, respectively. SBP was increased by 8% in spring and 19% in winter, and DBP was increased by 7% in winter. Our data suggest a certain prevalence of pre- or hypertension among young population, which is associated with short-term fluctuation and season-specific exposure of PM_2.5.

Mediating effect of telomere length in a hypertension population exposed to cadmium: a case-control study

Cadmium (Cd) is associated with telomere length and hypertension, respectively, but the mechanism behind its relationship is unclear. Our study aimed to clarify the role of telomere length in the relationship between Cd and hypertension. A 1:1 matched case-control study was conducted with 213 hypertensive patients and 213 normotensive controls in Taiyuan, Shanxi Province, China, from February and June 2016. General demographic characteristics information and lifestyle were collected using a structured questionnaire. Urine samples were collected to test urinary Cd (UCd) levels and corrected by urinary creatinine (UCr) levels. Peripheral leukocyte absolute telomere length (ATL) was measured using quantitative polymerase chain reaction. Logistic regression was used to screen the influencing factors of hypertension. A mediation effect analysis was used to explore the role of telomere length between Cd exposure and the risk of hypertension. We found that the hypertension group had a significantly higher UCd level compared to the control group (0.91 vs 0.80 μg/g Cr, P < 0.01), while ATL showed the opposite relationship (2.36 vs 2.65 kb, P < 0.01). The Regression analysis of hypertension identified these significant predictors: family history of hypertension (OR = 3.129, 95% confidence interval (95% CI): 1.767-5.540), Body mass index (BMI, OR = 1.088, 95% CI: 1.023-1.157), total cholesterol (TC, OR = 1.277, 95% CI: 1.024-1.592), UCd (OR = 2.092, 95% CI: 1.179-3.710), ATL (OR = 0.105, 95% CI: 0.025-0.453) and 8-hydroxy-2-deoxyguanosine (8-OHdG, OR = 7.864, 95% CI: 3.516-17.589). Mediating effect analysis revealed that ATL was a potential partial mediating factor between Cd and hypertension. Cd may induce hypertension by affecting telomere length, but this requires further exploration.
