Hypertension in the elderly

Ventricular-arterial coupling: changes with ageing and implications across cardiovascular conditions

PURPOSE

Ventricular-arterial coupling (VAC) is a crucial concept in cardiovascular physiology, representing the dynamic interaction between the left ventricle and the arterial system. This comprehensive literature review explores the changes in VAC with ageing and various cardiovascular diseases (CVDs).

MATERIALS AND METHODS

This literature review covers studies on changes in VAC with age and common CVDs, such as arterial hypertension, atrial fibrillation (AF) and heart failure with preserved and reduced ejection fraction and aortic stenosis (AS). The review discusses traditional measures of VAC, including arterial elastance (Ea) and ventricular elastance (Ees), as well as emerging parameters, such as global longitudinal strain (GLS) and pulse wave velocity (PWV). The review introduces the PWV/GLS ratio as a novel method for assessing VAC.

RESULTS

With ageing, both Ea and Ees increase, while the Ea/Ees ratio remains relatively stable, reflecting balanced arterial and ventricular adaptations. Novel measures, such as PWV/GLS ratio, show greater impairment in older adults and provide a comprehensive evaluation of VAC.

CONCLUSIONS

Ageing disrupts VAC through arterial stiffening and reduced heart function, often exacerbated by CVDs. Novel metrics like PWV/GLS may improve VAC assessment, helping clinicians manage age-related cardiovascular issues by identifying risks earlier and guiding treatment to support efficient heart-artery interaction.

Hypertension: A Continuing Public Healthcare Issue

Hypertension is a cardiovascular disease defined by an elevated systemic blood pressure. This devastating disease afflicts 30-40% of the adult population worldwide. The disease burden for hypertension is great, and it greatly increases the risk of cardiovascular morbidity and mortality. Unfortunately, there are a myriad of factors that result in an elevated blood pressure. These include genetic factors, a sedentary lifestyle, obesity, salt intake, aging, and stress. Although lifestyle modifications have had limited success, anti-hypertensive drugs have been moderately effective in lowering blood pressure. New approaches to control and treat hypertension include digital health tools and compounds that activate the angiotensin receptor type 2 (AT2), which can promote cardiovascular health. Nonetheless, research on hypertension and its management is vital for lessening the significant health and economic burden of this condition.

Blood pressure targets, medication consideration and unique concerns in elderly hypertension IV: Focus on frailty, orthostatic hypotension, and resistant hypertension

Hypertension increases the risk of cardiovascular disease in the elderly. Although treating hypertension can reduce the risk of cardiovascular disease and its related mortality, it is also challenging because these patients could have frailty, orthostatic hypotension (OH) and resistant hypertension (RHTN), which makes them more susceptible to treatment-related adverse events. Identifying such patients and tailoring the choice of drugs and blood pressure targets is crucial to balance the harms and benefits. The Clinical Frailty Scale is recommended to assess elderly patients with hypertension and frailty. For very frail patients, unnecessary medications should be deprescribed to avoid adverse events. Hypertension and OH frequently co-occur in the elderly, and recognizing and managing OH is essential to prevent falls and adverse events. The management of blood pressure in elderly patients with frailty, OH, and RHTN is complex, requiring the patients, their family and caregivers to be involved in decision-making to ensure that treatment plans are well-informed and aligned with the patient's needs.

The food environment and hypertension: A cross-sectional analysis in Black breast cancer survivors in Maryland

OBJECTIVES

The Food Environment Index (FEI) has shown varying positive impacts on health outcomes related to diabetes, obesity, and hypertension. However, a relationship between FEI and hypertension among breast cancer (BC) survivors, particularly Black women survivors, remains underexplored. Black women who are BC survivors have a high prevalence of hypertension and increased risk of mortality compared to White women with BC. Our analysis aims to fill this gap by assessing the FEI's association with hypertension in this population.

DESIGN

Utilizing social media recruitment strategies and BC survivor networks, 100 Black female BC survivors completed an online survey, that included sociodemographic and clinical characteristics as well as lifestyle factors. The 2023 FEI County Health Rankings was used to assess the food environment and the index ranges from 0 (worst) to 10 (best). Adjusted prevalence odds ratios (PORs) and 95 % confidence intervals (CI) were calculated for the associations between FEI, sociodemographic and clinical factors, and hypertension status.

RESULTS

Among the 94 study participants with data on hypertension status, 54.3 % reported a diagnosis of hypertension. Residing in counties with a below-median FEI (<8.8 v. above median: ≥8.8) was significantly associated with hypertension (POR = 4.10, 95 % CI: 1.19-14.13). Age at survey (≥50 years compared to <50 years: POR= 0.29, 95 % CI: 0.10-0.87) and household income ($75,000-$99,999 compared to > $99,999/year: POR = 12.02, 95 % CI: 2.08-69.43) were also significantly associated with hypertension.

CONCLUSION

Our study highlights the potential impact of the food environment on hypertension among Black BC survivors living in Maryland. Our findings call attention to the need for targeted interventions to improve food accessibility and quality in underserved communities, especially for special populations such as cancer survivors.

Uncontrolled blood pressure among the established hypertensive elderly people in Jashore, Bangladesh: A cross-sectional type of observational study

Objectives

Hypertension is one of the major modifiable risk factors for cardiovascular mortality and morbidity throughout the world. Increased life expectancy leads to increase prevalence of non-communicable diseases among the elderly people including Bangladesh. However, different studies reported high prevalence of uncontrolled hypertension ranging from 52.6% to 67.9% among the elderly people in different countries. With this view, we aimed to assess the frequency of uncontrolled blood pressure (BP) among the elderly hypertensive people and its associated risk factors and treatment pattern in Bangladesh.

Methodology

This cross-sectional type of observational study recruited 246 eligible hypertensive elderly patients attending in 250 Bedded General Hospital, Jashore, Bangladesh dated from 1st July to 31st December 2022. A structured questionnaire was developed and data on associated risk factors, treatment pattern and current blood pressure (BP) measurement were collected by face-to-face interview for the purposive sampling technique.

Results

The mean age of our study patients was 72 ± 7 years with a male and female ratio nearly 1:1. Of the total hypertensive patients aged over 65 years or more, 56.5% remained with uncontrolled hypertension even on their prescribed antihypertensive medications. The mean systolic (SBP) and diastolic (DBP) blood pressure were significantly high (P < 0.001) as 167 ± 22 mm Hg and 95 ± 11 mm Hg, respectively, among the uncontrolled hypertensive patients. However, we noticed the mean SBP and DBP among the total hypertensive patients were also significantly high (P < 0.001) as 148 ± 27 mm Hg and 87 ± 13 mm Hg, respectively. In this study, we reported that the mean number of last prescribed antihypertensive medications used by the total patients was 2 ± 1 (P =0.224) which was similar among the controlled and uncontrolled hypertensive patient groups. Among the elderly hypertensive patients, the most commonly prescribed antihypertensive medications were Amlodipine 39.8% (P =0.006), Olmesartan 29.3% (P = 0.186), Losartan 24.4% (P = 0.127), Bisoprolol 15.0% (P = 0.266) and Atenolol 14.6% (P = 0.224).

Conclusion

We noticed high frequency of uncontrolled blood pressure among the elderly hypertensive patients, despite of using multiple antihypertensive medications in Jashore, Bangladesh.

Coronary risk factor profiles according to different age categories in premature coronary artery disease patients who have undergone percutaneous coronary intervention

Many studies have investigated the coronary risk factors (CRFs) among premature coronary artery disease (PCAD) patients. However, reports on the proportion and CRFs of PCAD according to different age cut-offs for PCAD is globally under-reported. This study aimed to determine the proportion of PCAD patients and analyse the significant CRFs according to different age cut-offs among percutaneous coronary intervention (PCI)-treated patients. Patients who underwent PCI between 2007 and 2018 in two cardiology centres were included (n = 29,241) and were grouped into four age cut-off groups that defines PCAD: (A) Males/females: < 45, (B) Males: < 50; Females: < 55, (C) Males: < 55; Females: < 60 and (D) Males: < 55; Females: < 65 years old. The average proportion of PCAD was 28%; 9.2% for group (A), 21.5% for group (B), 38.6% and 41.9% for group (C) and (D), respectively. The top three CRFs of PCAD were LDL-c level, TC level and hypertension (HTN). Malay ethnicity, smoking, obesity, family history of PCAD, TC level and history of MI were the independent predictors of PCAD across all age groups. The proportion of PCAD in Malaysia is higher compared to other studies. The most significant risk factors of PCAD are LDL-c, TC levels and HTN. Early prevention, detection and management of the modifiable risk factors are highly warranted to prevent PCAD.

Associations between Supper Timing and Mortality from Cardiovascular Disease among People with and without Hypertension

AIM

Less is known about the impact of supper time on cardiovascular disease (CVD) risk among hypertensives and nonhypertensives. We aimed to explore this issue in a cohort study.

METHODS

We analyzed the data of 72,658 participants (15,386 hypertensives and 57,272 nonhypertensives) aged 40-79 years without a history of CVD at baseline (1988-1990) under the Japan Collaborative Cohort study. Supper time was assessed based on self-reported questionnaires categorized as before 17:00, between 17:00 and 20:00, after 20:00, irregular supper time, and reference supper time (17:00-20:00). Hazard ratios (HRs) and 95% confidence intervals (95% CI) of CVD mortality were calculated according to supper time after adjustment for potential confounders, stratified by hypertensive status and age group (＜65 and ≥ 65 years).

RESULTS

During a median of 19.4 years of follow-up, 4,850 CVD deaths were recorded. Compared with the reference time, the risk of CVD mortality was higher for irregular supper time for the total population, either hypertensives or nonhypertensives, more specifically hypertensives aged ≥ 65 years; the multivariable HR (95% CI) of CVD mortality in the total population was 1.28 (1.11-1.50, P＜0.01). The supper time of ＞20:00 tended to be associated with the higher risk only for hypertensives; the multivariable HR was 1.39 (0.98-1.96, P=0.06).

CONCLUSION

Irregular supper time was associated with an increased risk of CVD mortality. Supper timing could be a surrogate marker for CVD risk.

Optimal Systolic Blood Pressure for the Prevention of All-Cause and Cardiovascular Disease Mortality in Older Adults With Hypertension: Nationwide Population-Based Cohort Study

BACKGROUND

Target systolic blood pressure (SBP) levels for older adults with hypertension vary across countries, leading to challenges in determining the appropriate SBP level.

OBJECTIVE

This study aims to identify the optimal SBP level for minimizing all-cause and cardiovascular disease (CVD) mortality in older Korean adults with hypertension.

METHODS

This retrospective cohort study used data from the National Health Insurance Service database. We included older adults aged 65 years or older who were newly diagnosed with hypertension and underwent a National Health Insurance Service health checkup in 2003-2004. We excluded patients who had a history of hypertension or CVD, were not prescribed medication for hypertension, had missing blood pressure or any other covariate values, and had fewer than 2 health checkups during the follow-up period until 2020. We categorized the average SBP levels into 6 categories in 10 mm Hg increments, from <120 mm Hg to ≥160 mm Hg; 130-139 mm Hg was the reference range. Cox proportional hazards models were used to examine the relationship between SBP and all-cause and CVD mortalities, and subgroup analysis was conducted by age group (65-74 years and 75 years or older).

RESULTS

A total of 68,901 older adults newly diagnosed with hypertension were included in this study. During the follow-up period, 32,588 (47.3%) participants had all-cause mortality and 4273 (6.2%) had CVD mortality. Compared to older adults with SBP within the range of 130-139 mm Hg, individuals who fell into the other SBP categories, excluding those with SBP 120-129 mm Hg, showed significantly higher all-cause and CVD mortality. Subgroup analysis showed that older adults aged 65-74 years had higher all-cause and CVD mortality rates according to SBP categories than those aged 75 years or older.

CONCLUSIONS

The SBP levels within the range of 120-139 mm Hg were associated with the lowest all-cause and CVD mortality rates among older Korean adults with hypertension. It is recommended to reduce SBP to <140 mm Hg, with 120 mm Hg as the minimum value for SBP, for older Korean adults with hypertension. Additionally, stricter SBP management is required for adults aged 65-74 years.

The association between the urinary chromium and blood pressure: a population-based study

BACKGROUND AND AIM

The impact of trace elements and heavy metals on human health has attracted widespread attention. However, the correlation between urinary chromium concentrations and blood pressure remains unclear and inadequately reported, and the aim of this study was to investigate the relationship between urinary chromium concentrations and blood pressure in adults in the United States (US).

METHODS

We utilized data from the National Health and Nutrition Examination Survey (NHANES) 2017-2018 for this study. Multivariate logistic regression and multivariate linear regression were used to explore the association of urinary chromium concentrations with hypertension and blood pressure. Additionally, we also performed subgroup analysis and restricted cubic splines (RCS).

RESULTS

A total of 2958 participants were enrolled in this study. The overall mean systolic blood pressure and diastolic blood pressure were 123.98 ± 0.60, 72.66 ± 0.57 mmHg, respectively. The prevalence of hypertension was found in 41.31% of the whole participants. In the fully adjusted model, we did not observe a correlation between urinary chromium concentrations and the risk of hypertension and systolic blood pressure. However, we found a negative association between urinary chromium concentrations and diastolic blood pressure. In subgroup analysis, we observed a positive association between urinary chromium and the risk of hypertension among participants older than 60 years of age and those who were Non-Hispanic Black. The interaction term highlighted the influence of age and race on this positive association. We also found a negative association of urinary chromium with diastolic blood pressure in male, participants who were current smokers, overweight, and other races, as well as those without alcohol use and anti-hypertensive drug use. However, the interaction term only revealed the influence of alcohol consumption on the negative association.

CONCLUSION

Our study suggested that urinary chromium concentrations may show a negative association with diastolic blood pressure and this association was significantly dependent on alcohol consumption. Besides, a positive association between urinary chromium and the risk of hypertension was also found among participants older than 60 years of age and those who were Non-Hispanic Black.

No Association Between AGT Gene Polymorphisms with Hypertension in a South African Population

Purpose

Hypertension is a leading cause of cardiovascular-related morbidity and mortality worldwide, with a prevalence increasing at an alarming rate in both middle- and low-income countries. Various environmental and genetic factors have been attributed to play a significant role in the increasing prevalence of hypertension. Single nucleotide polymorphisms (SNPs) in the angiotensinogen (AGT) gene are reported to have a significant association with hypertension; however, there are limited studies done on South African populations. Therefore, this case-control study aimed to investigate the association between AGT SNPs (rs2004776, rs3789678, rs5051 and rs7079) with hypertension in a study population of isiXhosa-speaking participants from the Eastern Cape Province in South Africa.

Materials and Methods

The SNPs were genotyped in 250 hypertensive cases and 237 normotensive controls, using TaqMan genotyping assays.

Results

For the SNP rs2004776, the frequency of CC genotype (18.4%) and C allele (44%) in hypertensive cases showed no significant differences (p = 0.52, χ2 = 1.32), when compared to the normotensive control group (CC: 19.8% and C allele: 43%). Similar results were obtained for the genotypic and allelic frequencies between hypertensive cases and normotensive controls for rs3789678 (p = 0.88, χ2=0.26) and rs5051 (p = 0.57, χ2=1.12), and rs7079 (p = 0.33, χ2=2.23). These findings demonstrate that there were no significant associations between the SNPs rs2004776, rs3789678, rs7079, rs5051 with hypertension in our study population.

Conclusion

These findings suggest that AGT gene polymorphisms are not associated with the development of hypertension in the studied population. The present study represents the first genetic report to investigate the AGT gene polymorphisms with hypertension in an isiXhosa-speaking South African population.

Effect of Mat Pilates Training on Blood Pressure, Inflammatory, and Oxidative Profiles in Hypertensive Elderly

To determine the effects of mat Pilates training on blood pressure, inflammatory, and antioxidative markers in hypertensive elderly people, 34 hypertensive subjects aged 60-75 years were randomly divided into a control group (CON; n = 17) and a mat Pilates training group (MP; n = 17). The CON participants conducted normal daily activities and participated in neither organized exercises nor sports training, while those in the MP group received mat Pilates training for 60 min three times/week for 12 weeks. Parameters including blood pressure, cardiovascular function, nitric oxide (NO), tumor necrotic factor-alpha (TNF-α), superoxide dismutase (SOD), and malonaldehyde (MDA) were collected at baseline and the end of 12 weeks. The MP group had significantly decreased blood pressure, improved cardiovascular variables, decreased MDA and TNF-α, and increased NO and SOD compared with the CON group and the pre-training period (p < 0.05). In conclusion, these findings demonstrate the positive effects of 12 weeks of mat Pilates training in terms of reducing blood pressure and increasing blood flow related to improvements in anti-inflammatory and antioxidative markers in hypertensive elderly people. Mat Pilates training might be integrated as an alternative therapeutic exercise modality in clinical practice for hypertensive elderly individuals.

Slow on the Draw-ED Management of Elevated BP in Older Adults

PURPOSE OF REVIEW

The purpose of this study is to review data surrounding the emergency department management of elevated blood pressure in older adults, including the management of hypertensive crisis and outpatient management of markedly elevated blood pressure.

RECENT FINDINGS

Acute lowering of blood pressure in older adults with markedly elevated blood pressure may lead to serious complications without improvements in hospital length of stay, return visits, or mortality. Older adults presenting with elevated blood pressures without evidence of end-organ damage should be referred for outpatient management of their blood pressure. Treatment of hypertensive emergency should follow standard guidelines with additional considerations for aging physiology. Acute lowering of elevated blood pressure in older adults without evidence of end-organ damage has the potential for harm. If the emergency physician opts to acutely treat, they should consider the increased risk of side effects in older adults and avoid Beers list medications including short-acting nifedipine and clonidine.

The association between dolutegravir-based antiretrovirals and high blood pressure among adults with HIV in southern Ethiopia: a cross-sectional study

Background

Dolutegravir (DTG), a novel antiretroviral therapy (ART) for HIV, is increasingly adopted across sub-Saharan Africa. However, its impact on blood pressure in Ethiopia remains unclear, highlighting a need for further studies.

Objective

This study aimed to investigate the association between DTG-based first-line regimens and other covariates of high blood pressure (HBP) among adults living with HIV receiving care at health facilities in Hawassa City, southern Ethiopia.

Design

A cross-sectional study.

Methods

Data were collected between January 2023 and May 2024 among 444 systematically selected adults, complemented with a review of their medical records. HBP was defined according to the seventh report of the Joint National Committee (JNC7) guidelines, with a threshold of systolic or diastolic blood pressure of ⩾120/80 mmHg. Multivariable logistic regression analysis was performed to identify predictors of HBP. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were computed to determine statistically significant associations.

Results

Of the study participants, 58.3% were women and 41.7% were men, resulting in a response rate of 95.5%. The mean (standard deviation (SD]) age of the participants was 38.4(±8.9) years. The prevalence of HBP was 57.9% (95% CI: 52.5-62.4), with 40.5% classified as prehypertension and 17.3% as hypertension. Among participants with hypertension, 84.4% were newly diagnosed. Initiating ART with DTG-based regimens was associated with higher odds of HBP (AOR 5.9; 95% CI: 1.5-22.7) and switching to DTG-based regimens also increased the odds of HBP (AOR 3.8; 95% CI: 1.1-13.9). Other significant covariates associated with HBP included being male (AOR 2.6; 95% CI: 1.4-4.9), age >45 years (AOR 2.0; 95% CI: 1.2-3.4), high waist-to-height ratio (AOR 2.4; 95% CI: 1.1-4.9), inadequate vegetable intake (AOR 1.7; 95% CI: 1.0-2.7), low physical activity (AOR 2.4; 95% CI: 1.1-5.4), and LDL-cholesterol (AOR 1.1; 95% CI: 1.0-1.2).

Conclusion

Proactive blood pressure screening and management are important for individuals on DTG-based regimens. In addition, early identification and intervention of modifiable risk factors through comprehensive strategies and regular screenings are pivotal for improving cardiovascular health among individuals on ART.

Targeting Hypertension: A Review on Pathophysiological Factors and Treatment Strategies

Hypertension is one of the primary causes of cardiovascular diseases and death, with a higher prevalence in low- and middle-income countries. The pathophysiology of hypertension remains complex, with 2% to 5% of patients having underlying renal or adrenal disorders. The rest are referred to as essential hypertension, with derangements in various physiological mechanisms potentially contributing to the development of essential hypertension. Hypertension elevates the risk of cardiovascular disease (CVD) events (coronary heart disease, heart failure, and stroke) and mortality. First-line therapy for hypertension is lifestyle change, which includes weight loss, a balanced diet that includes low salt and high potassium intake, physical exercise, and limitation or elimination of alcohol use. Blood pressure-lowering effects of individual lifestyle components are partially additive, enhancing the efficacy of pharmaceutical treatment. The choice to begin antihypertensive medication should be based on the level of blood pressure and the existence of a high atherosclerotic CVD risk. First-line hypertension treatment includes a thiazide or thiazide-like diuretic, an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, and a calcium channel blocker. Addressing hypertension will require continued efforts to improve access to diagnosis, treatment, and lifestyle interventions.

Challenging experiences of the elderly with heart failure in the COVID-19 pandemic: a phenomenological study in Iran

BACKGROUND

Patients with heart failure (HF), especially the elderly, faced many challenges during the COVID-19 pandemic, which need to be explored. The present study aimed to analyse the challenging experiences facing the elderly with heart failure during the pandemic in Iran. To achieve this aim, a qualitative approach to research was employed.

METHODS

The present qualitative research employed a phenomenological approach to study 12 elderly with heart failure visiting Imam Ali Hospital during the COVID-19 pandemic in Kermanshah, Iran. The data collection occurred between August 5, 2022, and November 21, 2022. The participants were selected through a purposive sampling method and interviewed using a semi-structured interview. MAXQDA10 software was used for data organisation and the Colizzi analytical technique for data analysis. Guba and Lincoln's criteria were also used to evaluate the trustworthiness of the qualitative research.

RESULTS

A total of two categories, 8 subcategories, and 110 primary codes were extracted from the data. The two categories were challenges and coping strategies. The former included the sub-categories of economic issues, fear, anxiety, and fear of death; limited access to health care; quarantine issues; disruption of family life; and medication non-adherence. The subcategories of the latter were faith in God, social support, and self-care behaviors.

CONCLUSIONS

The present study revealed the challenges experienced and the coping strategies employed by elderly patients with heart failure during the pandemic in Iran. A knowledge of these challenges and experiences during the COVID-19 pandemic can raise healthcare workers' awareness of the elderly patients' strategies used to cope with the virus.

Effect of statins on hearing outcome in patients with idiopathic sudden sensorineural hearing loss

Objective

Statins have been reported to improve vascular endothelial function and microcirculation, reduce oxidative stress, and exert anti-inflammatory and protective effects against inner ear damage. Therefore, this study aimed to investigate the effect of statins on hearing prognosis in patients with idiopathic sudden sensorineural hearing loss (ISSNHL).

Methods

We reviewed the medical records of 149 patients diagnosed with ISSNHL. Clinical characteristics, hearing thresholds, statin medications, and hematological findings were investigated. First, patients with ISSNHL were assigned to the good and poor outcome groups, and factors influencing their prognosis were analyzed. Furthermore, patients with dyslipidemia were investigated to determine whether statins have therapeutic effects on ISSNHL.

Results

Significant differences in age (p = .011), days from the onset of ISSNHL to the initiation of treatment (p = .04), and hematological total cholesterol (TC; p = .015) between the good and poor outcome groups were observed. Furthermore, when hearing outcomes were investigated in patients with dyslipidemia, TC was significantly lower in the good outcome group (p = .03). Although no significant therapeutic effects of statins were observed in participants with dyslipidemia, patients in the statin-treated group were significantly older and experienced more diabetic complications than those in the non-statin-treated group.

Conclusion

Although our study showed that dyslipidemia is a poor prognostic factor for ISSNHL, statins had no significant therapeutic effects on hearing recovery in ISSNHL patients with dyslipidemia. The patients that received statin medications were significantly older and experienced more diabetic complications, which may have affected their hearing prognosis.

Six-Year Incidence of Visual Impairment in a Multiethnic Asian Population: The Singapore Epidemiology of Eye Diseases Study

Purpose

To examine the 6-year incidence of visual impairment (VI) and identify risk factors associated with VI in a multiethnic Asian population.

Design

Prospective, population-based, cohort study.

Participants

Adults aged ≥ 40 years were recruited from the Singapore Epidemiology of Eye Diseases cohort study at baseline. Eligible subjects were re-examined after 6 years. Subjects included in the final analysis had a mean age of 56.1 ± 8.9 years, and 2801 (50.5%) were female.

Methods

All participants underwent standardized examination and interviewer-administered questionnaire at baseline. Incidences were standardized to the Singapore Population Census 2010. A Poisson binomial regression model was used to evaluate the associations between baseline factors and incident presenting VI.

Main Outcome Measures

Incident presenting VI was assessed at the 6-year follow-up visit. Visual impairment (presenting visual acuity < 20/40), low vision (presenting visual acuity < 20/40 but ≥ 20/200), and blindness (presenting visual acuity < 20/200) were defined based on United States definition.

Results

A total of 5551 subjects (2188 Chinese, 1837 Indians, and 1526 Malays) were evaluated, of whom 514 developed incident presenting VI over 6 years. Malays had a higher incidence of low vision and blindness (13.0%; 0.6%) than Indians (7.0%; 0.1%) and Chinese (7.7%; 0.2%). Among Malay individuals with VI at baseline, 52.8% remained visually impaired after 6 years, which was considerably higher than Chinese (32.4%) and Indians (37.2%). Older age (per decade; relative risk [RR] = 1.59), a history of cardiovascular disease (RR = 1.38), current smoking (RR = 1.31), smaller housing type (1- to 2-room public flat; RR = 2.01), and no formal education (RR = 1.63) at baseline were associated with a higher risk of incident VI (all P ≤ 0.027). Older age (> 60 years) contributed the highest population attributable risk to incident VI (27.1%), followed by lower monthly income (Singapore dollar < $2000; 26.4%) and smaller housing type (24.7%). Overall, undercorrected refractive error (49.1%) and cataract (82.6%) were leading causes for low vision and blindness, respectively. This was consistently observed across the 3 ethnicities.

Conclusions

In this multiethnic Asian population, Malays had a higher VI incidence compared to Indians and Chinese. Leading causes of VI are mostly treatable, suggesting that more efforts are needed to further mitigate preventable visual loss.

Sacubitril/Valsartan in Heart Failure with Hypertension Patients: Real-World Experiences on Different Ages, Drug Doses, and Renal Functions

INTRODUCTION

Hypertension is a significant risk factor in heart failure for worldwide patients. More than half of hypertensive patients suffer from heart failure. Recently, sacubitril/valsartan (sac/val) has been approved as an antihypertensive agent in China and Japan. Additionally, it is not approved for treating hypertension in Europe or the USA.

AIM

To accumulate more real-world experiences to investigate the effectiveness and optimize clinical medication of sac/val in hypertensive patients with heart failure.

METHODS

We retrospectively enrolled adult patients diagnosed with hypertension (HTN) and heart failure (HF) and newly treated with sac/val. The baseline characteristics and clinical outcomes were retrospectively extracted from electronic medical records (EMR) in three centers. The efficacy and safety of sac/val were first analyzed in all enrolled patients. Stratified analyses were conducted in patients with different ages (≥ 65, < 65), maximum tolerated doses (≥ 200 mg/days, < 200 mg/days), and renal functions (e-GFR ≥ 60 ml/min/1.73 m2, < 60 ml/min/1.73 m2).

RESULTS

Overall, 794 patients diagnosed with both HF and HTN were included in our study. During follow-up, significant reductions were found in blood pressure (BP) (SBP 12.8 ± 21.2 mmHg, P < 0.001, DBP 7.1 ± 16.5 mmHg, P < 0.001), and cardiac biomarkers (cardiac troponin 1.78 ± 19.1 ng/mL, P < 0.001, NT-proBNP 1403 ± 6937 pg/mL, P < 0.001) from baseline. In stratification analyses, the lower dosage group earned a higher BP control rate (83.4% vs. 75.6%, P = 0.025) and an overall improvement rate of cardiac indicators (61.3% vs. 48.0%, P = 0.002). The younger patients' group had significantly less cumulative hazard of recurrent cerebral-cardiovascular events than the elder group (log-rank P value < 0.001). Patients with renal dysfunction were observed with more AE incidences.

CONCLUSIONS

Sac/val could reduce BP and improve cardiac structural and functional parameters in hypertensive patients with HF, even with less than target doses. However, more attention should be paid to older patients and renal dysfunction patients when using sac/val because of additional risks in adverse events.

Associations of leptin receptors and miRNA polymorphisms with susceptibility to hypertension

Leptin receptors (LEPR) are located in the central nervous system and other tissues including adipocytes and endothelial cells, where they play a key role in mediating the effects of leptin. MicroRNA (miR/miRNA)-27a and miR-155 have been shown to play an important role in the regulation of LEPR expression and are differentially expressed in various diseases. Therefore, the present study analyzed potential associations of LEPR deletion/insertion (Del/Ins), miR-27aA>G (rs895819) and miR-155T>A (rs767649) polymorphisms with a predisposition to hypertension (HTN). Genotyping was performed by a PCR-restriction fragment length polymorphism assay. Frequencies of LEPR Del/Ins and miRNA gene polymorphisms in patients diagnosed with HTN (n=232) and randomly selected healthy controls (n=247) were assessed. The present study found that Del/Ins and Ins/Ins genotypes and the Ins allele of the LEPR Del/Ins polymorphism were associated with a decreased risk of HTN compared with controls, whereas the miR-27aA>G rs895819 polymorphism was associated with an increased risk of HTN. Combined genotype and allele analyses for LEPR Del/Ins and two miRNA polymorphisms revealed an association with an increased risk or a decreased risk of HTN. Furthermore, stratification analysis revealed that HTN risk factors were associated with waist circumference (WC) and high-density lipoprotein cholesterol (HDL-C) values in LEPR Del/Ins polymorphism. They were also associated with body mass index, WC, triglyceride and HDL-C values in miR-27aA>G polymorphism. The present study revealed a combined effect of LEPR Del/Ins and miR-27aA>G polymorphisms on the risk of HTN in Koreans, suggesting that these gene polymorphisms could be potential markers for predicting HTN risk.

Vitamin D Supplementation and Sun Exposure Maintain Blood Pressures of Pregnant Women and Increase Birth Weight in a Randomized Controlled Trial

Background

Vitamin D supplementation or sun exposure increase pregnant women's Calcidiol levels, lower the blood pressures and increase birth weight. We aimed to compare the effects between sun exposure and vitamin D supplementation on pregnant women's Calcidiol levels, blood pressures and newborns' anthropometric indices.

Methods

This randomized clinical trial was conducted on 108 pregnant women at 20 wk of gestation on 2021's dry season in Semarang City, Indonesia. The subjects were randomly and evenly divided into 3 groups of 36 subjects (sunlight exposure, vitamin D supplement, and control). Vitamin D group received 1000 IU daily and sun exposure group was recommended to have 15-30 min for 3 times/week for 17 wk. Compliance was monitored every 2 d through home visits. Calcidiol levels, blood pressures, in all groups were compared before and after intervention. The increments and the newborn anthropometric indices were compared between the groups and controlled for confounding factors.

Results

At baseline, all groups had vitamin D deficiency, different mean Calcidiol levels, systolic, and diastolic blood pressures. The mean Calcidiol levels increased in the sun exposure and vitamin D group after the intervention. Systolic blood pressure decreased in the vitamin D group only (P=0.019). The mean birth weight was the highest in the vitamin D group (3,172±181.8 g) compared to the sun exposure (3,091±362.5g) and control groups (2,861 ± 208.0 g).

Conclusion

Vitamin D supplementation and sun exposure increased Calcidiol levels and birth weights. Vitamin D supplementation maintained systolic blood pressure.

Association between Low Blood Pressure and Subsequent Risk of Parkinson's Disease in Older Adults Aged ≥75 Years

INTRODUCTION

The association between blood pressure (BP) and incidence of Parkinson's disease (PD) in older adults remains uncertain. Therefore, this study aimed to investigate the association between BP (high or low) and PD incidence in adults aged ≥75 years.

METHODS

In this nationwide population-based cohort study, we enrolled participants aged ≥75 years without a prior PD diagnosis who had undergone health examination provided by the Korean National Health Insurance Service at least once from January 1, 2009, to December 31, 2012. The participants were followed up until December 31, 2019, or the date of their death. The Cox proportional hazards model was used to assess the risk of PD depending on systolic BP (SBP), diastolic BP (DBP), and pulse pressure.

RESULTS

Overall, 963,525 participants were enrolled in the analysis and followed up until December 31, 2019, or the date of death (40.7% male, mean age 78.5 ± 3.6 years). The mean SBP and DBP were 131.4 ± 16.7 and 77.9 ± 10.3 mm Hg, respectively. During the 10-year follow-up period, 16,414 (1.7%) newly diagnosed cases of PD were reported. A significant inverse dose-response association was found between SBP and PD incidence. In the subgroup analysis, this association was maintained for most variables, including sex, use of antihypertensive medication, comorbidities, alcohol consumption, physical activity, and body mass index, except for smoking status.

CONCLUSION

Lower SBP and DBP were associated with a higher PD incidence in older adults. These results may have substantial implications for determining the optimal BP control target in adults aged ≥75 years.

Prevalence of uncontrolled hypertension and its associated factors in 50-74 years old Iranian adults: a population-based study

BACKGROUND

By the lengthening of life span, the incidence of chronic diseases such as hypertension and uncontrolled hypertension has increased. This study aims to determine the prevalence of uncontrolled hypertension and its related factors in the age group of 50-74 years in Shahroud, northeast Iran.

METHODS

The data of the third phase of the Shahroud Eye Cohort Study were used in this study. This phase of the cohort study included 4394 participants aged 50 to 74 years from the previous phases. In addition to ophthalmological and optometric examinations, demographic characteristics, blood biochemistry tests, and blood pressure measurements were performed in this phase. Individuals with a blood pressure ≥ 140/90 mm/Hg (being treated or not treated with antihypertensive medicines) were defined as uncontrolled hypertension. In patients with diabetes and chronic kidney disease, blood pressure equal to or higher than 130/80 mm/Hg was considered uncontrolled hypertension. Descriptive statistics and multiple logistic regression were used to analyze the data.

FINDINGS

Overall, the prevalence of uncontrolled hypertension out of all the participants was 61.7% (95% CI: 60.3-63.2). Multiple regression results showed that the male gender (OR: 2.1, 95% CI: 1.5-2.9), patients with diabetes (OR:3.2, 95% CI: 2.4-4.3), and patients with chronic kidney disease (CKD) (OR: 3.2, 95% CI: 2.5-4.1) increased the risk of uncontrolled hypertension while in patients with cardiovascular disease (OR: 0.6, 95% CI: 0.4-0.8) and polypharmacy (OR: 0.2, 95% CI: 0.1-0.2) reduced the risk of uncontrolled hypertension.

CONCLUSION

The present study showed that uncontrolled hypertension has a high prevalence, and factors such as male gender, diabetes, and CKD are associated with this disorder. So, it is recommended to take the necessary measures to formulate and implement immediate actions to prevent or control hypertension.

The Epigenetic Regulation of RNA N6-Methyladenosine Methylation in Glycolipid Metabolism

The highly conserved and dynamically reversible N6-methyladenine (m6A) modification has emerged as a critical gene expression regulator by affecting RNA splicing, translation efficiency, and stability at the post-transcriptional level, which has been established to be involved in various physiological and pathological processes, including glycolipid metabolism and the development of glycolipid metabolic disease (GLMD). Hence, accumulating studies have focused on the effects and regulatory mechanisms of m6A modification on glucose metabolism, lipid metabolism, and GLMD. This review summarizes the underlying mechanism of how m6A modification regulates glucose and lipid metabolism-related enzymes, transcription factors, and signaling pathways and the advances of m6A regulatory mechanisms in GLMD in order to deepen the understanding of the association of m6A modification with glycolipid metabolism and GLMD.

Effectiveness and safety evaluation of sacubitril/valsartan in blood pressure control and clinical outcomes for elderly patients with heart failure and hypertension: A prospective cohort study

AIM

This study was conducted to investigate the safety and effectiveness of sacubitril/valsartan (sac/val) for elderly patients with hypertension and heart failure in the real-world setting.

METHODS

Patients with established hypertension complicated with structural or functional impairment of ventricular fillings [New York Heart Association (NYHA) functional class II-IV)] were enrolled. The effectiveness of sac/val in terms of BP reduction and improvement in frailty and echocardiographic evaluation of cardiac function were examined from baseline to 6-month administration.

RESULTS

Overall, 241 patients were treated with sac/val and 227 with renin angiotensin aldosterone system inhibitor (RAASi) for hypertension control. There were significant difference in the degree of systolic blood pressure reduction between two groups. Echocardiography showed that sac/val significantly improved left ventricular ejection fraction [4.0% (95% CI: 2.0-7.5) vs -1.0 (95% CI: -4.0-2.0), P = 0.001] during the follow-up visits. Significant improvements in NYHA function class and FRAIL scores post sac/val were observed after 3 and 6 month treatment. The rate of primary cardiovascular composite outcome was higher in patients in the RAASi group (26.9%; 95% CI: 19.6-34.0) than in the sac/val group (22.0%; 95% CI: 16.7-27.3).

CONCLUSIONS

Sac/val may be useful not only for reducing BP, but also for improving the structural and functional parameters of echocardiography, eventually resulting in a significant improvement of the overall symptomatic status, a significant reduction in NYHA class, and functional improvement.

Can the association between hypertension and physical activity be moderated by age?

Objectives

Physical inactivity, hypertension and non-communicable diseases are major public concerns across the globe. To our knowledge, there is a lack of research that has investigated the moderating effect of age on the relationship between hypertension and physical activity in developing countries. This study had two objectives: (1) investigating hypertension and sociodemographic factors associated with physical activity and (2) investigating whether age moderates the relationship between hypertension and physical activity.

Methods

Nationally representative data of Malaysia were used to generate cross-sectional evidence. The sample size was 2156 respondents. An ordered probit regression was utilized to assess factors associated with the practice of physical activity.

Results

Respondents aged 40-49 years with hypertension were 7.3% less likely to participate in high-level physical activity when compared to those without hypertension. The probability of having a low level of physical activity was 12.3% higher among hypertensive patients aged ≥60. Males, married individuals, less-educated adults, low-income earners, and individuals who were aware of their BMI, had a higher tendency to indulge in a highly active lifestyle than others.

Conclusion

The effect of hypertension on physical activity was moderated by age. Factors influencing physical activity levels among adults were income, gender, marital status, education, employment status, and BMI awareness.

Responses Triggered by the Immune System in Hypertensive Conditions and Repercussions on Target Organ Damage: A Review

BACKGROUND

Hypertension is a chronic, multifactorial clinical condition characterized by sustained high blood pressure levels. It is often associated with functional-structural alterations of target organs, which include heart, brain, kidneys, and vasculature.

OBJECTIVE

This study highlights the recent correlation between the immune system and hypertension and its repercussions on target-organ damage.

METHODS

The descriptors used for the search of the study were "hypertension", "immunity", and "target organs". The methodology of the study followed the main recommendations of the PRISMA statement.

RESULTS

The damage to the vasculature arises mainly from the migration of T cells and monocytes that become pro-inflammatory in the adventitia, releasing TNF-α, IFN-γ, and IL-17, which induce endothelial damage and hinder vascular relaxation. In the renal context, the inflammatory process associated with hypertension culminates in renal invasion by leukocytes, which contribute to the injury of this organ by mechanisms of intense sympathetic stimulation, activation of the reninangiotensin system, sodium retention, and aggravation of oxidative stress. In the cardiac context, hypertension increases the expression of pro-inflammatory elements, such as B, T, and NK cells, in addition to the secretion of IFN-γ, IL-17, IL-23, and TNF-α from angiotensin II, reactive oxygen species, and aldosterone. This pro-inflammatory action is also involved in brain damage through SphK1. In view of the above, the participation of the immune system in hypertension-induced injuries seems to be unequivocal.

CONCLUSION

Therefore, understanding the multifactorial mechanisms related to hypertension will certainly allow for more efficient interventions in this condition, preventing target organ damage.

The Effect of Multimedia-Based Education on Knowledge, Attitudes, and Behavior Hypertension Patients in Stroke Prevention

The prevalence of hypertension continues to increase, and various epidemiological studies revealed an increase in the incidence of hypertension in different parts of the world. According to the American Heart Association (AHA), The number of Americans over the age of 20 who suffer from hypertension has risen to 74.5 million, while nearly 90% of cases have no identified cause. If not treated effectively, hypertension may cause damage to blood vessels throughout the body, the most prominent of which is the danger of damage to the brain, eyes, heart, and kidneys. An introduction to stroke is essential for reducing the risk of stroke in people with hypertension. Multimedia is one of the developments in health education media, which is in accordance with the advancement of digital technology, incorporating stroke prevention. This study aims to examine the impact of multimedia-based education on hypertension patients' knowledge, attitudes, and behavior toward stroke prevention. This research is a quasi-experiment with a pre-posttest with a control group design. The sampling technique employed was simple random sampling, and the sample size determination utilized a hypothesis test of the average difference in two independent groups of 60 respondents. Data analysis in this study administered paired t-test and independent t-test. The results unveiled that there were significant differences in knowledge (p=0.022), attitudes (p=0.001), and behavior (p=0.008) of hypertension patients in preventing stroke after intervention in the form of multimedia-based education. Therefore, it is recommended that the community can perform hypertension treatment independently frequently, and the implementation of the prolanis program can be enhanced so that people can receive services easily and regularly to prevent stroke.

Pathophysiology, Diagnosis, and Management of Hypertension in the Elderly

There is a high prevalence of systemic arterial hypertension in the elderly; 70% of adults >65 years have this disease. A key mechanism in the development of hypertension in the elderly is increased arterial stiffness. This accounts for the increase in systolic blood pressure and pulse pressure and fall in diastolic blood pressure (isolated systolic hypertension) that are commonly seen in the elderly, compared with younger persons. The diagnosis of hypertension is made on the basis of in-office blood pressure measurements together with ambulatory and home blood pressure recordings. Lifestyle changes are the cornerstone of management of hypertension. Comprehensive guidelines regarding blood pressure threshold at which to start pharmacotherapy as well as target blood pressure levels have been issued by both European and American professional bodies. In recent years, there has been considerable interest in intensive lowering of blood pressure in older patients with hypertension. Several large, randomized controlled trials have suggested that a strategy of aiming for a target systolic blood pressure of <120 mm Hg (intensive treatment) rather than a target of <140 mm Hg (standard treatment) results in significant reduction in the incidence of adverse cardiovascular events and total mortality. A systolic blood pressure treatment of <130 mm Hg should be considered favorably in non-institutionalized, ambulatory, free living older patients. In contrast, in the older patient with a high burden of comorbidities and limited life expectancy, an individualized team-based approach, based on clinical judgment and patient preference should be adopted. An increasing body of evidence for older adults with hypertension suggests that intensive blood pressure lowering may prevent or at least partially prevent cognitive decline.

Green tea could improve elderly hypertension by modulating arterial stiffness, the activity of the renin/angiotensin/aldosterone axis, and the sodium-potassium pumps in old male rats

Hypertension is a major health problem common in the elderly people. Green tea is a popular beverage recommended in folk medicine for lowering blood pressure. However, the molecular mechanisms involved in the antihypertensive effects of green tea are not fully understood. Therefore, the aim of this study was to investigate the antihypertensive effects of green tea on high-salt diet-induced hypertension in old male rats. Forty old male rats were divided into five groups: control, hypertensive, and hypertensive-green tea (2, 4, and 6 g/kg). Heart rate (HR) and systolic blood pressure (SBP) were measured. Cardiac and renal histology were also performed. Lipid profile, NO, angiotensin II (Ang II), and aldosterone were determined, and the expression of eNOS, ATIR and ATIIR, aldosterone receptor, and Atp1a1 were measured. Green tea could significantly decrease HR and SBP, lipid profiles, renin-angiotensin II-aldosterone system activity, and Ang II signaling in kidney tissue of hypertensive rats (p < .01). It also increased Atp1a1, Nrf2, and eNOS expression along with antioxidant enzymes activity and NO concentration (p < .05) and decreased NF-ĸB and iNOS expression and IL-1β levels in the heart, kidneys, and aorta of rats with hypertension. It can be concluded that green tea can improve salt-induced blood pressure by modulating the function of the renin-angiotensin-aldosterone system, enhancing the synthesis of nitric oxide in the endothelium, increasing antioxidant activity and suppressing inflammation in the heart and kidney, improving the expression of the sodium-potassium pump, and reduction in serum lipids and glucose in aged male rats. PRACTICAL APPLICATIONS: The results of this study showed that green tea could improve hypertension in elderly rats by modulating (1) the expression of the sodium-potassium pump in the heart, kidney, and aortic tissues, (2) the activity of the renin-angiotensin II-aldosterone system in kidney, (3) enhancing antioxidant and anti-inflammatory activities in the heart, aorta, and kidneys, (4) enhancing the synthesis of nitric oxide in the endothelium, and (5) lowering lipid profile. The results of these studies show that the consumption of green tea and its products can be a good candidate for the prevention of cardiovascular diseases such as hypertension in the elderly. In addition, attention to its bioactive compounds can be considered by researchers as an independent therapeutic strategy or adjunctive therapy for the treatment of hypertension.

Predictors of 30-Day Readmission Following Cervical Laminoplasty in 3,085 Patients: An American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Database Study

Background Cervical laminoplasty is a surgical alternative to laminectomy and fusion for treating multi-level cervical spondylotic myelopathy. There is limited evidence evaluating readmission incidence and risk factors following cervical laminoplasty. Here, we provide a retrospective review evaluating preoperative risk for 30-day readmission following cervical laminoplasty. Methodology The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients undergoing laminoplasty as defined by Current Procedural Terminology codes 63050 and 63051. Patients were then categorized based on whether 30-day readmission occurred, and preoperative risk factors were examined. Continuous and categorical variables were analyzed using Student's t-test or Fisher's exact test. Multivariate regression analysis was performed for each variable, with p-values of <0.05 considered significant. Results In total, 3,085 patients were identified as undergoing posterior cervical laminoplasty. Of these, 2,938 patients did not require readmission, and 147 patients were readmitted, representing a 4.77% 30-day readmission rate. For all patients, sepsis (odds ratio (OR) = 5.58, p = 0.03), dialysis (OR = 3.46, p = 0.01), American Society of Anesthesiologists class >2 (OR = 1.69, p = 0.011), and hypertension (OR = 1.51, p = 0.04) were predictive of readmission. A subgroup analysis was performed for all geriatric patients (aged >65). In total, 1,353 patients were identified, of whom 76 were readmitted, demonstrating a readmission rate of 5.62%. For the elderly patients, hypertension (OR = 1.98, confidence interval (CI) = 1.04-3.75, p = 0.04) and independent status (OR = 0.39, CI = 0.21-0.74, p = 0.004) were predictive of readmission. Conclusions Assessment of predictors for readmission is important for patient education and setting appropriate clinical expectations for surgeons and providers. Preoperative hypertension, dialysis, and sepsis were risk factors for 30-day readmission following cervical laminoplasty, with functional status being a unique risk factor for elderly patients.

Metabolic syndrome and risk of death in older adults with major psychiatric disorders: Results from a 5-year prospective multicenter study

OBJECTIVES

No study has explored the association of individual components of metabolic syndrome with mortality in older patients with psychiatric disorders. In this report, we examined whether metabolic syndrome or any of its components predicted mortality in a cohort of older adults with psychiatric disorders.

METHODS

We used data from a multicenter 5-year prospective cohort, including 634 in- and out-patients with schizophrenia, bipolar or major depressive disorder. Metabolic syndrome was assessed at baseline following NCEP-ATPIII criteria. Cause of death was categorized as cardiovascular disorder (CVD) mortality, non-CVD disease-related mortality (e.g., infections), suicide and accident.

RESULTS

122 participants (44.0%) were diagnosed with metabolic syndrome at baseline. In the full sample, there was no significant association between metabolic syndrome or any of its components with all-cause, CVD and non-CVD mortality. However, for the subpopulation of older adults with major depressive disorder, metabolic syndrome was significantly associated with increased all-cause and disease-related mortality after adjustment for age, sex and smoking status (p = 0.032 and p = 0.036, respectively). There was a significant interaction between metabolic syndrome and psychiatric diagnoses indicating that in participants with major depressive disorder, metabolic syndrome had a significantly greater effect on all-cause mortality (p = 0.025) and on disease-related mortality (p = 0.008) than in participants with either bipolar disorder or schizophrenia.

CONCLUSIONS

Our findings do not support an association between metabolic syndrome and increased mortality in older patients with major psychiatric disorders. Several explanations are discussed, including a survival bias, a lack of sensitivity of the used cut-offs and a ceiling effect of metabolic syndrome on mortality in this very high-risk population. The latter hypothesis could also explain the significant association between metabolic syndrome and mortality in the depressive subgroup, where a ceiling effect is yet to be reached, given the less marked premature mortality in depressive patients compared to those with bipolar disorder or schizophrenia.

Involvement of AGE and Its Receptors in the Pathogenesis of Hypertension in Elderly People and Its Treatment

Both systolic and diastolic blood pressures increase with age up to 50 to 60 years of age. After 60 years of age systolic pressure rises to 84 years of age but diastolic pressure remains stable or even decreases. In the oldest age group (85-99 years), the systolic blood pressure (SBP) is high and diastolic pressure (DBP) is the lowest. Seventy percent of people older than 65 years are hypertensive. This paper deals with the role of advanced glycation end products (AGE) and its cell receptor (RAGE) and soluble receptor (sRAGE) in the development of hypertension in the elderly population. Plasma/serum levels of AGE are higher in older people as compared with younger people. Serum levels of AGE are positively correlated with age, arterial stiffness, and hypertension. Low serum levels of sRAGE are associated with arterial stiffness and hypertension. Levels of sRAGE are negatively correlated with age and blood pressure. Levels of sRAGE are lower in patients with arterial stiffness and hypertension than patients with high levels of sRAGE. AGE could induce hypertension through numerous mechanisms including, cross-linking with collagen, reduction of nitric oxide, increased expression of endothelin-1, and transforming growth factor-β (TGF-β). Interaction of AGE with RAGE could produce hypertension through the generation of reactive oxygen species, increased sympathetic activity, activation of nuclear factor-kB, and increased expression of cytokines, cell adhesion molecules, and TGF- β. In conclusion, the AGE-RAGE axis could be involved in hypertension in elderly people. Treatment for hypertension in elderly people should be targeted at reduction of AGE levels in the body, prevention of AGE formation, degradation of AGE in vivo, downregulation of RAGE expression, blockade of AGE-RAGE interaction, upregulation of sRAGE expression, and use of antioxidants.

Prevalence and determinants of unmet needs for hypertension care among the older population in Selangor: cross-sectional study

BACKGROUND

Hypertension is a major cause of morbidity and mortality worldwide. Although multiple studies have assessed the prevalence of hypertension among older people, no study has examined the unmet need for hypertension care among older people in Malaysia. This study uses the hypertension care cascade to identify the prevalence of unmet needs for hypertension care and their determinants among the older population in Selangor.

METHODS

This is a cross-sectional study involving a total of 1204 participants recruited from different areas in Selangor. A face-to-face interview was conducted using the Bahasa Malaysia version of the Japan Gerontological Evaluation Study questionnaire. The inclusion criteria were Malaysians aged ≥ 60 years who could converse in Bahasa Malaysia.

RESULTS

Among the 637 participants with hypertension, 18% (117) had not been previously screened but were found to have BP ≥ 140/90 mmHg, 21% (136) were undiagnosed, 3% (17) were untreated, 42% (267) were treated with antihypertensive medication but still had high blood pressure, and 16% (100) had hypertension that was controlled with medication. The hypertension care cascade demonstrates that 18% (117) of those with hypertension had never been screened for hypertension; 26% (136/520) of those who were screened never received a diagnosis; 4% (17/384) of those who were diagnosed did not receive treatment; and 73% (267/367) of those who were treated did not reach the threshold for control. The prevalence of total unmet needs was 84% (537/637). Statistically significant determinants of having any unmet need for hypertension care were smoking status and medical history, with adjusted odds ratios and 95% confidence intervals (CIs) in the multivariate analysis of 0.5 (95% CI: 0.3-0.9) for being a smoker, 2.8 (95% CI: 1.1-6.9) for having a history of stroke and 1.6 (95% CI: 1.0-2.5) for having a history of diabetes mellitus.

CONCLUSIONS

The prevalence of unmet need for hypertension care among the older population in Selangor is 84% (537/637), which is alarmingly high. This study highlights where and how much of the loss of care for hypertension happens in the care cascade and provides insight into the efforts required to improve effective service coverage to manage the increasing burden of hypertension associated with population ageing.

Screening for hypertension-mediated organ damage and aetiology: still of value after 65 years of age?

BACKGROUND

Secondary forms and hypertension-mediated organ damage (HMOD) may differ between younger and older hypertensive patients. The aim of the present study was to explore the specificity of HMOD and secondary forms in patients ≥ 65 years in comparison to younger ones in a contemporary cohort.

METHODS

We analysed 938 patients recruited between 2004 and 2014 (Cardiology department, Croix-Rousse Hospital, Lyon) who had at baseline HMOD and secondary forms screening among them 190 were ≥ 65 years.

RESULTS

The mean (2.1 ± 0.8 vs. 1.2 ± 0.9, P < 0.001) and frequency of HMOD (96.3% vs. 72.9%, P < 0.001) was higher in patients ≥ 65 years than younger ones. Carotid femoral pulse wave velocity > 10 m/s was the most frequent HMOD in patients ≥ 65 years (90.1%), while echocardiographic left ventricular hypertrophy was the most common in the younger patients (45.0%). Among ECG left ventricular indexes, only R wave in aVL lead was significantly more frequently observed in patients ≥ 65 years (32.6%) than in younger ones (19.0%, P < 0.001). The frequency of secondary hypertension was not significantly different between younger and older patients (respectively; 30.5% vs. 27.8%, P = 0.487). The most frequent aetiology was primary aldosteronism regardless of age, followed by renovascular hypertension (6.3% vs. 3.3%, P = 0.038). Among older patients, 3.2% were treated with adrenalectomy and 6.3% with percutaneous transluminal renal angioplasty.

CONCLUSION

Extensive screening of HMOD in older patients may be questionable as nearly all patients had one; aetiology must however be explored as a third of older patients had a secondary form.

Metabolomic Response throughout 16 Weeks of Combined Aerobic and Resistance Exercise Training in Older Women with Metabolic Syndrome

Increases in longevity and obesity have led to a higher prevalence of Metabolic Syndrome (MetS) and several chronic conditions, such as hypertension. The prevalence of MetS and hypertension increases with advancing age and their detrimental effects on health can be attenuated by physical activity. Combined aerobic and resistance exercise training (CT) is recommended to maintain good health in older adults and is known to generate important metabolic adaptations. In this study we performed a metabolomics analysis, based on Hydrogen Nuclear Magnetic Resonance (1H NMR), to investigate the kinetics of changes in metabolism in non-physically active older women with MetS in response to 16 weeks of CT. A subset of women with MetS were selected from a larger randomized trial (that included men and women without MetS), with 12 participants on CT and 13 from the Control Group (CG). CT comprised walking/running at 63% of VO2max, three times/week, and resistance training (RT), consisting of 15 repetitions of seven exercises at moderate intensity, twice/week. Serum metabolomic profile was analysed at baseline (0W), 4 (4W), 8 (8W), 12 (12W) and 16 weeks (16W) for CT or CG. Cardiorespiratory fitness, RT load, blood pressure, body composition, lipid and glycaemic profile were also assessed. After 16 weeks CT increased cardiorespiratory fitness (13.1%, p < 0.05) and RT load (from 48% in the lat pulldown to 160% in the leg press, p < 0.05), but there were no changes in MetS parameters, such as body composition (Body Mass, Body Mass Index (BMI), body fat percentage and waist circumference), blood pressure, lipid and glycaemic profile. However, we identified potential higher substrate to the tricarboxylic acid cycle (increase in 2-Oxobutyrate from 0W (0.0029 ± 0.0009) to 4W (0.0038 ± 0.0011) and 8W (0.0041 ± 0.0015), p < 0.05), followed by alterations (different from 0W, p < 0.05) in the production of ketone bodies (3-Hydroxybutyrate, 0W (0.0717 ± 0.0377) to 16W (0.0397 ± 0.0331), and Acetoacetate, 0W (0.0441 ± 0.0240) to 16W (0.0239 ± 0.0141)), which together might explain the known improvement in fatty acid oxidation with exercise. There was also a late increase in ornithine at 16W of CT. Further studies are needed to investigate the association between these metabolic pathways and clinical outcomes in this population.

Influence of acute and chronic intermittent hypoxic-hyperoxic exposure prior to aerobic exercise on cardiovascular risk factors in geriatric patients-a randomized controlled trial

Background: Intermittent hypoxic-hyperoxic exposure (IHHE) and aerobic training have been proposed as non-pharmacological interventions to reduce age-related risk factors. However, no study has yet examined the effects of IHHE before aerobic exercise on cardiovascular risk factors in the elderly. Therefore, the aim of this study was to investigate the acute and chronic effects of IHHE prior to aerobic cycling exercise on blood lipid and lipoprotein concentrations as well as blood pressure in geriatric patients. Methods: In a randomized, controlled, and single-blinded trial, thirty geriatric patients (72-94 years) were assigned to two groups: intervention (IG; n = 16) and sham control group (CG; n = 14). Both groups completed 6 weeks of aerobic cycling training, 3 times a week for 20 min per day. The IG and CG were additionally exposed to IHHE or sham IHHE (i.e., normoxia) for 30 min prior to aerobic cycling. Blood samples were taken on three occasions: immediately before the first, ∼10 min after the first, and immediately before the last session. Blood samples were analyzed for total (tCh), high-density (HDL-C), and low-density lipoprotein cholesterol (LDL-C), and triglyceride (Tgl) serum concentration. Resting systolic (SBP) and diastolic blood pressure (DBP) was assessed within 1 week before, during (i.e., at week two and four), and after the interventions. Results: The baseline-adjusted ANCOVA revealed a higher LDL-C concentration in the IG compared to the CG after the first intervention session (ηp 2 = 0.12). For tCh, HDL-C, Tgl, and tCh/HDL-C ratio there were no differences in acute changes between the IG and the CG (ηp 2 ≤ 0.01). With regard to the chronic effects on lipids and lipoproteins, data analysis indicated no differences between groups (ηp 2 ≤ 0.03). The repeated measures ANOVA revealed an interaction effect for SBP (ηp 2 = 0.06) but not for DBP (ηp 2 ≤ 0.01). Within-group post-hoc analysis for the IG indicated a reduction in SBP at post-test (d = 0.05). Conclusion: Applying IHHE prior to aerobic cycling seems to be effective to reduce SBP in geriatric patients after 6 weeks of training. The present study suggests that IHHE prior to aerobic cycling can influence the acute exercise-related responses in LDL-C concentration but did not induce chronic changes in basal lipid or lipoprotein concentrations.

Congregational health needs by key demographic variables: Findings from a congregational health needs assessment tool

Health needs assessments identify important issues to be addressed and assist organizations in prioritizing resources. Using data from the Mid-South Congregational Health Survey, top health needs (physical, mental, social determinants of health) were identified, and differences in needs by key demographic variables (age, sex, race/ethnicity, education) were examined. Church leaders and members (N = 828) from 92 churches reported anxiety/depression (65 %), hypertension/stroke (65 %), stress (62 %), affordable healthcare (60 %), and overweight/obesity (58 %) as the top health needs in their congregations. Compared to individuals < 55 years old and with a college degree, individuals ≥ 55 years old (ORrange=1.50-1.86) and with ≤ high school degree (ORrange=1.55-1.91) were more likely to report mental health needs (anxiety/depression; stress). African Americans were less likely to report physical health needs (hypertension/stroke; overweight/obesity) than individuals categorized as Another race/ethnicity (ORrange=0.38-0.60). Individuals with ≤ high school degree were more likely to report affordable healthcare as a need compared to individuals with some college or a college degree (ORrange=1.58). This research highlights the need for evaluators and planners to design programs that are comprehensive in their approach to addressing the health needs of congregations while also considering demographic variation that may impact program participation and engagement.

Inflammatory cytokines are associated to lower glomerular filtration rate in patients with hypertensive crisis

Introduction

Hypertension and kidney function are closely related. However, there are few studies on renal function during acute elevation of blood pressure (BP), denominated hypertensive crisis (HC).

Objectives

To evaluate the relationship between renal function and inflammatory cytokines in HC, subdivided into hypertensive urgency (HUrg) and emergency (HEmerg).

Materials and methods

This cross-sectional study was carried out in 74 normotensive (NT) and 74 controlled hypertensive individuals (ContrHT) followed up in outpatient care. Additionally, 78 subjects with hypertensive emergency (HEmerg) and 50 in hypertensive urgency (HUrg), attended in emergency room, were also evaluated. Hypertensive crisis was classified into HEmerg, defined by systolic blood pressure (BP) ≥ 180 mmHg and/or diastolic BP ≥ 120 mmHg in presence of target-organ damage (TOD), and HypUrg, clinical situation with BP elevation without TOD. The glomerular filtration rate (eGFR) was estimated, and cytokine levels were measured. Statistical analysis was performed using the Kruskal-Wallis or Mann-Whitney test and Spearman’s correlation, with significant differences p-value &lt; 0.05.

Results

The median age was 53.5 years in the NT group (52 female), 61 years in the ContrHT group (52 female), and 62.5 years in the HC group (63 female) (p-value &lt; 0.0001). The median BP was 118.5/75 mmHg for NT, 113.5/71 for ContrHT, and 198.5/120 mmHg for HC, respectively (p-value &lt; 0.0001 among groups). BP and heart rate levels were significantly higher in the HC group compared to the NT and ContrHT groups (P &lt; 0.001 for all). The eGFR was significantly lower in HC group compared to the NT and ContrHT groups. The cytokine levels were higher in the HEmerg and HUrg groups compared to ContrHT group (P &lt; 0.0001, except for IL-1β in HUrg vs. ContrHT), without difference between the acute elevation of BP groups. Thus, all cytokines were significantly elevated in patients with HC compared to the control groups (NT and ContrHT). There was a negative correlation between eGFR and the cytokines (IL-1β, IL-6, IL-8, IL-10, and TNF-α) in the HC group.

Conclusion

Elevated inflammatory cytokines are associated with reduced eGFR in individuals with HC compared to control groups, suggesting that the inflammatory process participates in the pathogenesis of acute elevations of BP.

Prevalence of chronic kidney disease and associated factors among patients visiting renal unit of St. Paul's Hospital Millennium Medical College, Addis Ababa, Ethiopia: A cross-sectional study design

Objective:

This study aimed to assess the magnitude of chronic kidney disease among patients attending the renal unit of St. Paul’s Hospital Millennium Medical College, Addis Ababa, Ethiopia.

Methods:

Institution-based cross-sectional study was conducted among 620 randomly selected patients who visited St. Paul’s Hospital Millennium Medical College renal unit from 1 January to 31 December, 2019. Data on sociodemographic characteristics, clinical conditions, behavioral risk factors, electrolytes, and renal function tests were extracted from patients’ medical records. To enter and analyze data, EpiData 3.1 and SPSS 22 were used, respectively. Bivariable and multivariable logistic regression analyses were conducted to see the association between predictor variables and chronic kidney disease. Adjusted odds ratio at 95% confidence interval was used to describe significant association. A p-value <0.05 was considered to declare an association between chronic kidney disease and independent variables.

Results:

Of 620 patients, 139 (22.4%; 95% confidence interval: 19.2, 25.6) and 61 (9.8%; 95% confidence interval: 7.4, 12.3) had chronic kidney disease using cut-off value of 90 and 60 ml/min/1.73 m², respectively. Having urinary tract obstruction (adjusted odds ratio = 2.32; 95% confidence interval: 1.32, 4.06), hypertension (adjusted odds ratio = 4.06; 95% confidence interval: 2.50, 6.59), diabetes mellitus (adjusted odds ratio = 2.80; 95% confidence interval: 1.62, 4.85), cardiovascular disease (adjusted odds ratio = 2.54; 95% confidence interval: 1.60, 4.01), and age (adjusted odds ratio = 1.83; 95% confidence interval: 1.44, 3.57), family history of chronic kidney disease (adjusted odds ratio = 2.26; 95% confidence interval: 1.36, 3.75) were factors positively associated with having chronic kidney disease.

Conclusion:

Nearly, one out of five and one out of ten patients who visited the renal unit had chronic kidney disease using the two thresholds as a cut value. Patients with concomitant urinary tract obstruction, age, hypertension, diabetes mellitus, cardiovascular disease, and a family history of chronic kidney disease were more likely to develop chronic kidney disease. Regular screening for chronic kidney disease, optimal blood sugar, and blood pressure management should be practiced.

Implementing DASH-aligned Congregate Meals and Self-Measured Blood Pressure in two senior centers: An open label study

BACKGROUND AND AIMS

Cardiovascular Disease (CVD) poses significant health risks for seniors, especially among low-income and minority communities. Senior centers offer multiple services. We tested whether implementing two evidence-based interventions- DASH-aligned meals provided through an existing congregate meal program, and support for home Self-Measured Blood Pressure (SMBP) monitoring-lowers blood pressure among participants at two senior centers serving low-income, racially diverse communities.

METHODS AND RESULTS

Open-label study, enrolling clients aged ≥60, eating ≥4 meals/week at two NYC senior centers. Participants received DASH-aligned congregate meals, and training in nutrition, BP management education, and personal SMBP device. Co-Primary outcomes: a) change in systolic BP measured by independent health professionals, and b) change in percent with "controlled BP" (Eighth Joint National Committee (JNC-8) Guidelines), at Month 1 compared to Baseline.

SECONDARY OUTCOMES

Changes in BP at Months 3 and 5/6 (last measure). We enrolled 94 participants; COVID closures interrupted implementation mid-study. Mean systolic BP at Month-1 changed by -4.41 mmHg (n = 61 p = 0.07) compared to Baseline. Participants with controlled BP increased (15.7%) at Month 1. Change in mean BP at Month 1 was significantly correlated with BMI (p = 0.02), age (p = 0.04), and baseline BP (p < 0.001). Mean systolic SMBP changed by -6.9 mmHg (p = 0.004) at Months 5/6.

CONCLUSIONS

Implementing an evidence-based multi-component BP-lowering intervention within existing congregate meal programs at senior centers serving minority and low-income communities is feasible, and early findings show promising evidence of effectiveness. This approach to cardiovascular risk reduction should be further tested for widespread adoption and impact. Registered on ClinicalTrials.gov NCT03993808 (June 21st, 2019).

The Impact of Community Empowerment Programs on Oral Health Education for Knowledge Improvement in the Elderly

Objective This study aims to assess whether community empowerment as a health promotion program can improve the knowledge of the elderly and develop self-awareness about their oral health. The elderly population has increased in number and needs special attention, especially regarding the improvement of hygiene and health. Community empowerment is a type of health promotion program that can take the form of counseling and providing knowledge about oral health to the elderly.

Materials and Methods Participants are elderly aged 60 years or older. Counseling was done by oral medicine specialists and residents to provide knowledge about oral health problems. Assessment of knowledge improvement was done using pretest and posttest in a written questionnaire.

Statistical Analysis The Shapiro–Wilk test followed by the Wilcoxon test was used to compare the difference before and after counseling.

Results From a total of 38 elderly included in this study, 29 (76.32%) showed an improved score in posttest compared with pretest. Statistical analysis showed a significant difference between pretest and posttest scores of study participants (p < 0.005).

Conclusion Counseling in empowerment programs can help the elderly improve their knowledge about oral health, so that improvements can be expected to be followed by the development of self-awareness in the future.

Cardiovascular prevention in elderly patients

In recent decades, life expectancy has been increasing significantly. In this scenario, health interventions are necessary to improve prognosis and quality of life of elderly with cardiovascular risk factors and cardiovascular disease. However, the number of elderly patients included in clinical trials is low, thus current clinical practice guidelines do not include specific recommendations. This document aims to review prevention recommendations focused in patients ≥ 75 years with high or very high cardiovascular risk, regarding objectives, medical treatment options and also including physical exercise and their inclusion in cardiac rehabilitation programs. Also, we will show why geriatric syndromes such as frailty, dependence, cognitive impairment, and nutritional status, as well as comorbidities, ought to be considered in this population regarding their important prognostic impact.

Utility of Obesity Indicators for Predicting Hypertension among Older Persons in Limpopo Province, South Africa

In view of the epidemic proportions of obesity in South Africa and its relationship to cardiometabolic diseases, such as hypertension, a cross sectional study was conducted to investigate the utility of obesity indicators for predicting hypertension among older persons (≥60 years, n = 350) in the Limpopo Province of South Africa. The WHO STEPwise approach was used to collect data on demographic and lifestyle factors. Anthropometrics and blood pressure were measured according to the standard procedures. Receiver operating characteristic curves (ROC) were used to investigate and compare the ability of obesity indicators to predict overall hypertension and either increased systolic (SBP) or increased diastolic (DBP) blood pressure. The area under the ROC curve (AUC) was used to assess a certain indicator’s potential to predict overall hypertension and either increased SBP or increased DBP. Multivariate logistic regression analysis was used to determine the relationship of hypertension with obesity indicators. The mean age of the participants was 69 years (±SD = 7), and hypertension (46%), general obesity (36%) and abdominal obesity (57%) were prevalent among older persons. The obesity indicator body mass index (BMI) (AUC = 0.603 (0.52; 0.69)) was the best predictor of hypertension in older men. Waist circumference (WC) (AUC = 0.640 (0.56; 0.72)) and waist-to-height ratio (WHtR) (AUC = 0.605 (0.52; 0.69)) were better predictors of hypertension than BMI and waist-to-hip ratio (WHR) in older women. After adjustment for risk factors, only WC (AOR = 1.22 (1.16; 1.79)) was significantly associated with hypertension in older women, proposing WC as a screening tool for the prediction of hypertension in South African older women.

The Role of Lipid Rafts and Membrane Androgen Receptors in Androgen’s Neurotoxic Effects

Sex differences have been observed in multiple oxidative stress–associated neurodegenerative diseases. Androgens, such as testosterone, can exacerbate oxidative stress through a membrane androgen receptor (mAR), AR45, localized to lipid rafts in the plasma membrane. The goal of this study is to determine if interfering with mAR localization to cholesterol-rich lipid rafts decreases androgen induced neurotoxicity under oxidative stress environments. We hypothesize that cholesterol-rich caveolar lipid rafts are necessary for androgens to induce oxidative stress generation in neurons via the mAR localized within the plasma membrane. Nystatin was used to sequester cholesterol and thus decrease cholesterol-rich caveolar lipid rafts in a neuronal cell line (N27 cells). Nystatin was applied prior to testosterone exposure in oxidatively stressed N27 cells. Cell viability, endocytosis, and protein analysis of oxidative stress, apoptosis, and mAR localization were conducted. Our results show that the loss of lipid rafts via cholesterol sequestering blocked androgen-induced oxidative stress in cells by decreasing the localization of mAR to caveolar lipid rafts.

Prevalence and associated risk factors of hypertension and pre-hypertension among the adult population: findings from the Dubai Household Survey, 2019

BACKGROUND

Minimal data is available on the prevalence and correlates of hypertension and prehypertension in Dubai. The study aims to measure the prevalence of hypertension and pre-hypertension and the associated socio-demographic characteristics, behavioral risk factors and comorbidities among the adult population of Dubai.

METHODS

This study used data from the Dubai Household Health Survey, 2019. A cross-sectional population survey based on a complex stratified cluster random design. The total eligible sample included 2530 adults (18+). Sociodemographic and behavioral factors were considered as independent covariates. The main study outcome variables, pre-hypertension and hypertension, were ordinal, with normotension as the reference group.

RESULTS

The overall prevalence of hypertension in adults was 32.5% (38.37% in males and 16.66% in females). Prehypertension was prevalent in 29.8% of adults in Dubai (28.85% in males and 32.31% in females). The multivariate logistic regression analysis revealed that age groups, gender, occupation, and high Body Mass Index were significantly associated with a higher risk of hypertension at the level of P < 0.05. No clear trend toward a higher correlation of hypertension was noted with the increase in age, except after the age of 50 years. Males were five- times more likely to be hypertensive than females. Participants enrolled in skilled and service works had a five times higher risk of hypertension, compared with the reference group (professionals). Obese subjects had a 5.47-times greater correlation of hypertension compared with normal-weight subjects. Physically active individuals were less likely to develop hypertension. For the correlates with prehypertension in the present analysis, skilled and service workers and those working in elementary jobs had a higher risk of prehypertension, compared with the reference group (professionals) Individuals with a status of overweight were associated with a higher prevalence of prehypertension compared with people of normal weight.

CONCLUSIONS

This study showed a high prevalence of prehypertension and hypertension among adults in Dubai. Some socio-demographic and behavioral risk factors were correlated with prehypertension and hypertension among the studied population. Interventions aiming at increasing public awareness about such risk factors are essential.

Association between Knowledge and Self-care Adherence among Elderly Hypertensive Patient in Dwelling Community

BACKGROUND: Hypertension contributes significantly to the increase in cardiovascular disease cases, especially in the elderly. Knowledge and self-care compliance are needed, but in reality, awareness and regularity of control are still lacking in hypertensive patients in urban communities. AIM: The aim of the study was to determine the relationship of knowledge with self-care and get an overview of existing knowledge and self-care in the elderly with hypertension. METHODS: This is a quantitative and cross-sectional design recruited 383 hypertensive patients in three community health centers. Sampling with proportional random sampling from three health centers that have the highest cases of hypertension in the city of Padang. Knowledge instrument using hypertension knowledge-level scale. Moreover, hypertension self-care adherence using hypertension self-care activity level effects. Analysis using Chi-square test RESULTS: The sample of this study was 383 respondents. About 66.3% are women, 88.3% have low education, and 86.9% do not work. 51.2% had duration of hypertension 0–5 years and the average age was 60.89 ± 8.072 years. About 94.8% of respondents have poor knowledge. Self-care practice showed 64% non-adherence to medication, 88.5% non-adherence to the DASH diet, and 82.5% non-adherence to weight management. However, 78.6% indicated non-smoking adherence and 100% alcohol avoidance adherence. There was a relationship between knowledge and adherence to weight management (p=0.000; odds ratio [OR] 6.7 (95% confidence interval [CI] for Exp B; 2.65–16.91)) and physical activity (p=0.000; OR 14.99 (95% CI for Exp B; 5.65–39.79)). CONCLUSION: Providing comprehensive and repeated health education for the elderly with hypertension can increase their knowledge. The involvement of patients and families is needed to improve self-care behavior.

How Does COVID-19 Pandemic Impact on Incidence of Clostridioides difficile Infection and Exacerbation of Its Gastrointestinal Symptoms?

Coronavirus disease 2019 (COVID-19) has rapidly spread all over the world with a very high rate of mortality. Different symptoms developed by COVID-19 infection and its impacts on various organs of the human body have highlighted the importance of both coinfections and superinfections with other pathogens. The gastrointestinal (GI) tract is vulnerable to infection with COVID-19 and can be exploited as an alternative transmission route and target for virus entry and pathogenesis. The GI manifestations of COVID-19 disease are associated with severe disease outcomes and death in all age groups, in particular, elderly patients. Empiric antibiotic treatments for microbial infections in hospitalized patients with COVID-19 in addition to experimental antiviral and immunomodulatory drugs may increase the risk of antibiotic-associated diarrhea (AAD) and Clostridioides difficile infection (CDI). Alterations of gut microbiota are associated with depletion of beneficial commensals and enrichment of opportunistic pathogens such as C. difficile. Hence, the main purpose of this review is to explain the likely risk factors contributing to higher incidence of CDI in patients with COVID-19. In addition to lung involvement, common symptoms observed in COVID-19 and CDI such as diarrhea, highlight the significance of bacterial infections in COVID-19 patients. In particular, hospitalized elderly patients who are receiving antibiotics might be more prone to CDI. Indeed, widespread use of broad-spectrum antibiotics such as clindamycin, cephalosporins, penicillin, and fluoroquinolones can affect the composition and function of the gut microbiota of patients with COVID-19, leading to reduced colonization resistance capacity against opportunistic pathogens such as C. difficile, and subsequently develop CDI. Moreover, patients with CDI possibly may have facilitated the persistence of SARS-CoV-2 viral particles in their feces for approximately one month, even though the nasopharyngeal test turned negative. This coinfection may increase the potential transmissibility of both SARS-CoV-2 and C. difficile by fecal materials. Also, CDI can complicate the outcome of COVID-19 patients, especially in the presence of comorbidities or for those patients with prior exposure to the healthcare setting. Finally, physicians should remain vigilant for possible SARS-CoV-2 and CDI coinfection during the ongoing COVID-19 pandemic and the excessive use of antimicrobials and biocides.

Acute Hemodynamic Responses to Three Types of Hamstrings Stretching in Senior Athletes

Although stretching is recommended for fitness and health, there is little research on the effects of different stretching routines on hemodynamic responses of senior adults. It is not clear whether stretching can be considered an aerobic exercise stimulus or may be contraindicated for the elderly. The purpose of this study was to compare the effect of three stretching techniques; contract/relax proprioceptive neuromuscular facilitation (PNF), passive straight-leg raise (SLR), and static sit-and-reach (SR) on heart rate (HR) and blood pressure (BP) in senior athletes (119 participants: 65.6 ± 7.6 yrs.). Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and HR measurements were taken at baseline (after 5-minutes in a supine position), 45 and 90-seconds, during the stretch, and 2-minutes after stretching. Within each stretching group, (SLR, PNF, and SR) DBP, MAP and HR at pre-test and 2-min post-stretch were lower than at 45-s and 90-s during the stretch. SLR induced smaller increases in DBP and MAP than PNF and SR, whereas PNF elicited lower HR responses than SR. In conclusion, trained senior adult athletes experienced small to moderate magnitude increases of hemodynamic responses with SLR, SR and PNF stretching, which recovered to baseline values within 2-min after stretching. Furthermore, the passive SLR induced smaller increases in BP than PNF and SR, while PNF elicited lower HR responses than SR. These increases in hemodynamic responses (HR and BP) were not of a magnitude to be clinically significant, provide an aerobic exercise stimulus or warrant concerns for most senior athletes.
