Abstract Background The evolution of cognitive impairment of vascular origin is increasingly becoming a prominent health threat particularly in this era where hypertension is the leading contributor of global disease burden and overall health loss. Hypertension is associated with the alteration of the cerebral microcirculation coupled by unfavorable vascular remodeling with consequential slowing of mental processing speed, reduced abstract reasoning, loss of linguistic abilities, and attention and memory deficits. Owing to the rapidly rising burden of hypertension in Tanzania, we sought to assess the prevalence and correlates of cognitive impairment among hypertensive patients attending a tertiary cardiovascular hospital in Tanzania. Methodology A hospital-based cross-sectional study was conducted at Jakaya Kikwete Cardiac Institute, a tertiary care public teaching hospital in Dar es Salaam, Tanzania between March 2020 and February 2021. A consecutive sampling method was utilized to recruit consented hypertensive outpatients during their scheduled clinic visit. General Practitioner Assessment of Cognition (GPCOG) Score was utilized in the assessment of cognitive functions. All statistical analyses utilized STATA v11.0 software. Pearson Chi square and Student’s T-test were used to compare categorical and continuous variables respectively. Logistic regression analyses were used to assess for factors associated with cognitive impairment. Odd ratios with 95% confidence intervals and p-values are reported. All tests were 2-sided and p < 0.05 was used to denote a statistical significance. Results A total of 1201 hypertensive patients were enrolled in this study. The mean age was 58.1 years and females constituted nearly two-thirds of the study population. About three quarters had excess body weight, 16.6% had diabetes, 7.7% had history of stroke, 5.7% had heart failure, 16.7% had renal dysfunction, 53.7% had anemia, 27.7% had hypertriglyceridemia, 38.5% had elevated LDL, and 2.4% were HIV-infected. Nearly two-thirds of participants had uncontrolled blood pressure and 8.7% had orthostatic hypotension. Overall, 524 (43.6%) of participants had cognitive impairment. During bivariate analysis in a logistic regression model of 16 characteristics, 14 parameters showed association with cognitive functions. However, after controlling for confounders, multivariate analysis revealed ≤primary education (OR 3.5, 95%CI 2.4–5.2, p < 0.001), unemployed state (OR 1.7, 95%CI 1.2–2.6, p < 0.01), rural habitation (OR 1.8, 95%CI 1.1–2.9, p = 0.01) and renal dysfunction (OR 1.7, 95%CI 1.0–2.7, p = 0.04) to have independent association with cognitive impairment. Conclusion This present study underscore that cognitive decline is considerably prevalent among individuals with systemic hypertension. In view of this, it is pivotal to incorporate cognitive assessment in routine evaluation of hypertensive patients.

Moreover, our observation suggests that low education, rural life, unemployment status and renal dysfunction interactions with elevated blood pressure has the potential to predict cognitive performance over time. As the effective disease-modifying treatments for cognitive impairment are lacking, these findings imply that several modifiable risk factors including hypertension represents a potentially vital mechanism for prevention or delay of cognitive impairment.

Abstract Background Hypertension (HTN) and hyperhomocysteinemia (HHcy) have been reported to be independent predictors of cognitive impairment. However, the conclusions were inconsistent and few studies had reported the combination prediction of HTN and HHcy for cognitive impairment. Our study aimed to evaluate the association between H-type HTN, HTN and HHcy and the risk of cognitive impairment.Methods We used a cross-sectional study- participants aged over 40 years, which were selected from Kailuan communities in China. Cognitive impairment was determined by MMSE scale (MMSE<24). Multivariable logistic regression was used to analyze the association of H-type HTN and cognitive impairment, and we also made stratification analysis by age of participants.Results A total of 3454 participants were included in our study, and ≥65 years old was 16.79%; the gender of male was 56.77%. The prevalence of cognitive impairment in the H-type HTN (HTN+/HHcy+) group (10.74%) was significantly higher than other three groups (2.92%, 6.42%, 5.86%, respectively). The logistic regression results showed that participants with H-type HTN was positively associated with cognitive impairment risk (OR = 2.57, 95% CI: 1.38-4.80). Similar results were observed in participants stratified by age (65 years) (<65 years old: OR =2.01, 95% CI: 0.87- 4.67 ; ≥65 years old: OR=3.63, 95% CI: 1.32-10.01).Conclusion Our finding indicated that H-type HTN was positively associated with the risk of cognitive impairment, especially in ≥ 65 years old. H-type HTN could be the major intervention measures to decrease the incidence of cognitive impairment as well as the stroke in Health Practice Management.

Background: Medication adherence is the mainstay to good treatment outcomes. Failure to adhere to medication in hypertensive patients may lead to considerable deterioration of the disease resulting in increased costs of healthcare and mortality. Knowledge about the name of the drug, indications and side effects may enhance medication adherence. Therefore, the aim of this study was to assess effects of medication knowledge on medication adherence among hypertensive patients.Methods: This was a cross-sectional study that involved 120 hypertensive patients. A structured questionnaire was used to collect data on demographic characteristics. Adherence was assessed using the 8-item Morisky medication adherence scale while patient’s medication knowledge was assessed using a 7-item scale. Multiple logistic regression was used to assess factors associated with medication adherence.Results: The mean age of participants was 59 years (SD±14.9) and 10 (8.3%), 42 (35%) and 68 (56.7%) had adequate, average and poor medication knowledge respectively. The prevalence of adherence in this study was 37.5%. In multivariable logistic regression analysis, uncontrolled blood pressure (BP) (AOR: 0.38, CI: 0.16-0.90) was associated with lower likelihood of adhering to medication.Conclusions: The adherence level to treatment was low and medication knowledge of hypertensive patients was generally poor. Uncontrolled BP was associated with non-adherence. Patients with uncontrolled hypertension should be given health education and counselling regarding their condition to improve medication adherence.

Abstract Background:The burden of depression is higher among people with chronic illnesses like hypertension and this comorbid condition leads to poor adherence to treatment and failure of compliance to lifestyle modifications, which in turn, increases risk of cardiovascular complications and mortalities. Low income countries, Ethiopia included, suffer from paucity of information describing the burden of hypertension comorbid with depression, which demands studies to narrow this knowledge gap, such as this one.Methods:Institution based cross-sectional study was conducted in three randomly selected public hospitals in Addis Ababa. Through a systematic random sampling method, a total of 416 known hypertensive patients with follow up in hypertension clinics with in the study period enrolled in the study. Data were collected through structured questionnaire administered by trained interviewer, which latter cleaned, edited and entered in to epi-data version 3.1. Descriptive and bi-variable and binary logistic regression analysis were done using the statistical software, SPSS version 25. Depression was assessed through Hospital Anxiety and Depression Scale (HADs).ResultsThe prevalence of depression among hypertensive patients was found to be 37.8%. The binary logistic regression model revealed that, female sex [AOR = 5.37, 95% CI (3.089–9.35)], being married [AOR = 0.25, 95% CI (0.08–0.78)], presence of chronic comorbid illnesses [AOR = 3.03, 95% CI (1.78–5.16)], uncontrolled blood pressure [AOR = 2.80, 95% CI (1.65–4.75)], duration of hypertension of 5–10 years [AOR = 3.17, 95% CI (1.61–6.23)] and more than 10 years [AOR = 5.81, 95% CI (2.90-11.65)], family history of depression [AOR = 4.53, 95% CI (2.37–8.66)] and current alcohol consumption [AOR = 1.77, 95% CI (1.02–3.07)] were significantly associated with depression among hypertensive patients.ConclusionHigher proportion of depression was observed among hypertensive patients, and socio-demographic, clinical and behavioral characteristics were found to significantly influence the likelihood of occurrence. Health care providers should consider mental health status of hypertensive patients, and counsel for these factors.

Background: Cognitive impairment in patients with human immunodeficiency virus (HIV) is associated with higher morbidity. The prevalence of and the metabolite changes in the brain associated with cognitive impairment in anti-retroviral therapy naïve patients with HIV is unknown. Objective: To estimate the prevalence of, and the neurometabolites associated with cognitive impairment in antiretroviral therapy (ART) naïve patients with HIV. Methods: We conducted a cross-sectional study among ART naïve patients with HIV aged 18-50 years in a tertiary care center in India. Cognition was tested using the Post Graduate Institute battery of brain dysfunction across five domains; memory, attentioninformation processing, abstraction executive, complex perceptual, and simple motor skills. We assessed the total N-acetyl aspartyl (tNAA), creatine (tCr) and glutamate + glutamine (Glx) using 3T magnetic resonance spectroscopy. Cognitive impairment was defined as an impairment in ≥2 domains. Results: Among 43 patients eligible for this study, the median age was 32 years (IQR 29, 40) and 30% were women. Median CD4 count and viral load were 317 cells/µL (IQR 157, 456) and 9.3 copies/ µL (IQR 1.4, 38), respectively. Impairment in at least one cognitive domain was present in 32 patients (74.4%). Impairment in simple motor skills and memory was present in 46.5% and 44% of patients, respectively. Cognitive impairment, defined by impairment in ≥2 domains, was found in 22 (51.2%) patients. There was a trend towards higher concentration of tNAA (7.3 vs. 7.0 mmol/kg), tGlx (9.1 vs. 8.2 mmol/kg), and tCr (5.5 vs. 5.2 mmol/kg) in the frontal lobe of patients with cognitive impairment vs. without cognitive impairment but it did not reach statistical significance (p>0.05 for all). There was no difference in the concentration of these metabolites in the two groups in the basal ganglia. Conclusions: There is a high prevalence of cognitive impairment in ART naïve patients with HIV. There is no difference in metabolites in patients with or without cognitive impairment. Further studies, with longitudinal follow-up, are required to understand the underlying pathophysiological mechanisms.

Background: The prevalence of gastroesophageal reflux disease (GERD) is increasing worldwide and the related chronic symptoms can be associated with morbidity and poor quality of life. Objective: The objective of this study was to identify foods and beverages consumed by the Lebanese population, dietary habits, socio-demographic and lifestyle factors, health parameters and perceived stress, implicated in increasing GERD symptoms. Methods: This observational cross-sectional study was carried among Lebanese adults in 2016. A convenient sample of 264 participants was equally divided into a GERD group and a control group. Data on socio-demographic characteristics, lifestyle, health status and dietary habits including Lebanese traditional dishes were collected. The perceived stress scale (PSS) was also used to assess the participants’ perception of stress. Logistic regression analyses were conducted with GERD symptoms (presence or absence) being the dependent variable. Results: The GERD symptoms were significantly associated with age (-p-value=0.017), family history of GERD symptoms (-p-value<0.001), smoking (-p-value=0.003) and chronic medical conditions (-p-value<.001). Regarding the dietary factors, participants who ate three meals or less/day, between meals and outside homes were 2.5, 2.9 and 2.4 times at a higher risk of experiencing GERD symptoms than others, respectively. Moreover, the logistic regression model showed that the GERD symptoms were significantly associated with the consumption of coffee (-p-value=0.037), Lebanese sweets (-p-value=0.027), fried foods (-p-value=0.031), ‘Labneh’ with garlic (-p-value<0.001), pomegranate molasses (-p-value=0.011), and tomatoes (-p-value=0.007). Conclusion: Some specific lifestyle factors and components of the Lebanese Mediterranean diet could be associated with GERD symptoms.
