Safety, efficacy and delivery of isometric resistance training as an adjunct therapy for blood pressure control: a modified Delphi study

Uncontrolled hypertension remains the major risk factor for cardiovascular disease. Isometric resistance training (IRT) has been shown to be a useful nonpharmacological therapy for reducing blood pressure (BP); however, some exercise physiologists and other health professionals are uncertain of the efficacy and safety of IRT. Experts’ consensus was sought in light of the current variability of IRT use as an adjunct treatment for hypertension. An expert consensus-building analysis (Delphi study) was conducted on items relevant to the safety, efficacy and delivery of IRT. The study consisted of 3 phases: (1) identification of items and expert participants for inclusion; (2) a two-round modified Delphi exercise involving expert panelists to build consensus; and (3) a study team consensus meeting for a final item review. A list of 50 items was generated, and 42 international experts were invited to join the Delphi panel. Thirteen and 10 experts completed Delphi Rounds 1 and 2, respectively, reaching consensus on 26 items in Round 1 and 10 items in Round 2. The study team consensus meeting conducted a final item review and considered the remaining 14 items for the content list. A final list of 43 items regarding IRT reached expert consensus: 7/10 items on safety, 11/11 items on efficacy, 10/12 items on programming, 8/10 items on delivery, and 7/7 on the mechanism of action. This study highlights that while experts reached a consensus that IRT is efficacious as an antihypertensive therapy, some still have safety concerns, and there is also ongoing conjecture regarding optimal delivery.

Dietary Adherence and Associated Factors among Hypertensive Patients in Bahir Dar City Administration, Ethiopia, 2020

Introduction: Hypertension is considered one of the most challenging public health problems worldwide. Adherence to the recommended diet has a key role to reduce uncontrolled hypertension and hypertension-related complications. A study on dietary adherence among hypertensive patients and associated factors are limited in Ethiopia. So,this study aimed to assess dietary adherence and associated factors among hypertensive patients in Bahir Dar city governmental hospitals, Bahir Dar, Ethiopia. Method: A cross-sectional study was conducted at Bahir Dar city governmental hospitals from February- March 2020. Proportional allocation and systematic random sampling techniques were used to select 386 individuals with hypertension. The logistic regression model was used to assess the association between predictors and dietary adherence. The association was interpreted using the odds ratio and 95% confidence interval. Result: In this the proportion of dietary adherence was 32.8% (CI: 28.0, 37.6). Educational level college and above (AOR=3.0, CI=1.26, 7.08), received nutritional education (AOR=1.9, CI=1.05, 3.62), knowledgeable about hypertension (AOR=2.5, CI=1.36, 4.58), who had no co-morbidities (AOR=2.8, CI=1.49, 5.20), who lived two to four years with hypertension (AOR=2.4, CI=1.17, 5.07), and who had strong social support (AOR=7.1, CI=2.85, 17.46) had significantly association with dietary adherence. Conclusion and recommendations: This study demonstrated that low proportion of hypertensive individuals were adhered to recommended diet. Therefore, availed a social network of family and friends; providing dietary education to address the participants’ knowledge of hypertension, promote survival skill to new diagnosed and considered co-morbidities are an integral part of overall health in people with hypertension.

Effectiveness of radiofrequency renal denervation in diseases with increased sympathetic nervous system activity

The article discusses the role of sympathetic nervous system hyperactivity in the pathogenesis of various pathologies (hypertension, heart failure, atrial fibrillation, metabolic syndrome, diabetes and systemic inflammatory response syndrome). On the example of large randomized clinical trials using catheter-based radiofrequency ablation, the antihypertensive effect in patients with uncontrolled hypertension has been proven. The first experimental and clinical studies on the effectiveness of renal denervation in reducing the activity of inflammatory markers, the incidence of atrial fibrillation and ventricular arrhythmia episodes, and improving the left ventricular contractility. The first clinical results of the favorable effect of renal denervation on carbohydrate metabolism (insulin resistance and glycemic level) in patients with metabolic syndrome and diabetes have been studied in detail.

COVID-19: a trigger for severe thrombotic microangiopathy in a patient with complement gene variant

The evidence regarding thrombotic microangiopathy (TMA) related to Coronavirus Infectious Disease 2019 (COVID-19) in patients with complement gene mutations as a cause of acute kidney injury (AKI) are limited. We presented a case of a 23-year-old male patient admitted with an asymptomatic form of COVID-19, but with uncontrolled hypertension and AKI. Kidney biopsy showed severe lesions of TMA. In evolution patient had persistent microangiopathic hemolytic anemia, decreased level of haptoglobin and increased LDH level. Decreased complement C3 level and the presence of schistocytes were found for the first time after biopsy. Kidney function progressively decreased and the patient remained hemodialysis dependent. Complement work-up showed a heterozygous variant with unknown significance in complement factor I (CFI) c.-13G>A, affecting the 5' UTR region of the gene. In addition, the patient was found to be heterozygous for the complement factor H (CFH) H3 haplotype (involving the rare alleles of c.-331C>T, Q672Q and E936D polymorphisms) reported as a risk factor of atypical hemolytic uremic syndrome. This case of AKI associated with severe TMA and secondary hemolytic uremic syndrome highlights the importance of genetic risk modifiers in the alternative pathway dysregulation of the complement in the setting of COVID-19, even in asymptomatic forms.

A Prospective Study of Azilsartan Medoxomil in the Treatment of Patients with Essential Hypertension and Type 2 Diabetes in Asia

This phase 4 study evaluated the efficacy and safety of azilsartan medoxomil (AZL-M) in patients with essential hypertension and type 2 diabetes mellitus (T2DM) in Hong Kong, Taiwan, and Thailand. This was a prospective, multicenter, single-arm, open-label study with patients aged 18–75 years with T2DM and essential hypertension and on stable treatment for T2DM. Patients with uncontrolled hypertension were treated with AZL-M 40 mg daily, with the option to uptitrate to 80 mg at 6 weeks. In all, 380 of the 478 patients screened in Hong Kong, Taiwan, and Thailand were enrolled. At week 6, 97 patients (25.5%) were titrated up to AZL-M 80 mg based on BP readings. At 12 weeks, 54.8% of patients reached the blood pressure (BP) goal of <140/85 mm Hg by trough sitting clinic BP (primary endpoint), and 62.8% and 27.0% achieved a BP of <140/90 mm Hg and <130/80 mm Hg, respectively. The efficacy of AZL-M over 12 weeks was also seen in different age and body mass index groups. The incidence of treatment emergent adverse events (TEAEs) was 12.9% before 6 weeks and 16.1% after 6 weeks, and they were mostly mild in severity. The most frequent TEAE was dizziness (4.7%). The incidence of TEAEs leading to study drug discontinuation (4.5%) and drug-related TEAEs (5.0% before 6 weeks; 3.9% after 6 weeks) was low. In patients with essential hypertension and T2DM in Asia, treatment with AZL-M indicated a favorable efficacy and safety profile in achieving target BP.

Association of education levels with the risk of hypertension and hypertension control: a nationwide cohort study in Chinese adults

BackgroundEducation attainment can improve life expectancy and guide healthy behaviours throughout an entire lifetime. A nationwide longitudinal study of the association of education status with the risk of hypertension and its control in China is lacking.MethodsThe China Cardiometabolic Disease and Cancer Cohort Study is a multicentre, population-based, prospective cohort study. We performed the baseline survey from 2011 to 2012. A follow-up visit was conducted during 2014–2016. 101 959 subjects were included in the final data analyses. Cox proportional hazards regression was used to examine the associations of education levels with the risk of hypertension and uncontrolled hypertension.ResultsDuring follow-up, 11 189 (19.9%) participants had developed hypertension among subjects without hypertension at baseline. Among the participants with hypertension at baseline, only 40.6% had controlled hypertension. Compared with the participants’ education level at elementary school and below, the multivariable-adjusted HR for incident hypertension was 0.76 (95% CI, 0.72 to 0.80) in those with a middle school education level and 0.67 (95% CI, 0.63 to 0.70) in those with a high school degree or above. Correspondingly, multivariable-adjusted HRs associated with uncontrolled hypertension were 0.90 (95% CI, 0.87 to 0.92) in participants with a middle school education level and 0.85 (95% CI, 0.82 to 0.88) in participants with a high school degree or above level.ConclusionParticipants with education attainment at elementary school and below exhibited excess risks of newly diagnosed hypertension and worse blood pressure control compared with individuals with education attainment at middle school or above.

Unilateral nodular adrenocortical hyperplasia presenting as Cushing’s syndrome: a case report

Cushing syndrome results from chronic exposure to excess cortisol. Nodular adrenal hyperplasia is usually bilateral and has only a few case reports of unilateral presentation. Biochemically it is presented as hyperaldosteronism or as Cushing’s syndrome. Here, we are reporting a 17-year-old female presenting with weight gain over 5 months and uncontrolled hypertension. Biochemically she was found to have diabetes mellitus, secondary hypothyroidism and hypogonadotrophic hypogonadism due to Cushing’s syndrome of adrenal origin. Unilateral adrenal adenoma/hyperplasia in right adrenal gland was evident by radiology. Histopathological examination was done after laparoscopic adrenalectomy showed nodular adrenocortical hyperplasia in right adrenal mass. Following surgery, clinical features of the patient improved notably. Cushing syndrome due to unilateral nodular adrenocortical hyperplasia is a rare entity. Biochemical evaluation of hypothalamo-pituitary-adrenal axis, radiological evidence and histopathology are the important armaments can guide to final diagnosis. BIRDEM Med J 2022; 12(1): 78-82

Factors Affecting the Incidence of Uncontrolled Hypertension in Patients Performing Routine Examinations at the Kebayakan Public Health Center, Central Aceh Regency

The purpose of the study was to determine the factors that influence the incidence of uncontrolled hypertension in patients who carry out routine checks at the Community Health Center (Puskesmas). Method: using analytical survey method using Case Control research design. The sample was 148 respondents, 74 case groups and 74 control groups were taken by purposive sampling. Data analysis was performed univariate, bivariate and multivariate with multiple logistic regression. The results of the bivariate test showed that the factors influencing the incidence of uncontrolled hypertension were age (p= 0.002; OR = 3,253), family history (p= 0.000; OR = 4.216), obesity (p= 0.005; OR = 2.734), physical activity (p= 0.000; OR = 4.229), salt consumption (p= 0.000; OR = 4,127), coffee consumption (p= 0.010; OR = 4,127), stress (p= 0.000; OR = 3,745), medication adherence (p= 0.000; OR = 4.492). Factors that were not related were gender (p= 0.620; OR = 0.803), smoking (p= 1,000; OR = 1,000). While the results of the multivariate test showed that the most influential factors with the incidence of uncontrolled hypertension were medication adherence variable (p= 0.000; Exp(B) = 5.982), and obesity variable (p= 0.002; Exp(B) = 4.945). In conclusion, the dominant factors that influence the incidence of uncontrolled hypertension at the Kebayakan Health Center are medication adherence and obesity.
