Background: Antiretroviral therapy has improved HIV patients’ quality of life and life expectancy. However, complications have emerged in the form of hypertension. In the rural Eastern Cape, there is minimal information about HIV-infected people. The current study intended to evaluate the factors associated with hypertension in HIV-infected individuals receiving antiretroviral therapy in rural areas of South Africa’s Eastern Cape. Methods: For this cohort study, HIV-positive people taking antiretroviral therapy aged 15 and up were recruited at random from several rural locations in the Eastern Cape. Using Cox univariate and multivariate analyses, the key predictors of hypertension were found. Results: Of the total participants (n = 361), 53% of individuals had hypertension. In the Cox multivariate model, patients that had hypertension heredity, BMI ≥ 25 kg/m2, eGFR < 60 mL/min/1.73 m2, advanced and severe CD4 counts, 1TFE and 1T3E regimens, and the male gender were found to be at greater risk of hypertension. Conclusions: The findings of this study indicate that hypertension is a prevalent concern among HIV patients receiving antiretroviral therapy. HIV patients should have their blood pressure checked regularly, and they should be screened for high blood pressure and given treatment for it.

Human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) leads to immune suppression, and micronutrients play vital roles in human immune responses. Hence, this study aimed to evaluate the effects of viral load suppression in adult HIV-infected patients receiving antiretroviral therapy (ART) on micronutrient deficiency and its prevalence in selected rural districts in the Eastern Cape Province of South Africa. This cross-sectional study was conducted from February 2019 to February 2021 among 50 consenting HIV-infected patients attending community health centers within the three selected districts. The data were analysed with ArcGIS v.10.8 to create geospatial maps; the Global Positioning System (GPS) for analysis and presentation; and SPSS version 25 for inferential statistics involving the t-test and Fisher’s exact test, with the level of significance set at p < 0.05. Of the 50 participants, a significant difference of p = 0.003 was observed in mean age among viral load-suppressed (42.9 ± 8.89 years) and unsuppressed (32 ± 6.3 years). In addition, significant differences in the mean viral load and CD4 counts (p < 0.05) were seen. Only iron micronutrient showed a statistically significant difference (p < 0.001) between the viral load-suppressed group (mean 14.8, SD 6.1) and the unsuppressed group (mean 8.1, SD 1.6). Of the 38 individuals from the OR Tambo district, overall micronutrient deficiency was 60.5% (13 (34.2%) deficient for zinc, 9 (23.7%) deficient for iron, 5 (13.2%) for folate, and 1 (2.63%) for vitamin D). In all three study districts, deficiencies in zinc, iron, and folate micronutrients exceeded 25%, particularly in those with an unsuppressed viral load. To address these micronutrient deficiencies, people living with HIV (PLHIV) require robust nutritional supplementation programs.

Globally, cancer is a leading cause of death, with cervical cancer ranking second among all cancers. Its adversity impacts not only individuals but also families, societies, and governments. The quality of services, as informed by the knowledge and adequacy of the health workers, plays an important role in both prevention, diagnosis, and management of the disease. A cross-sectional study among 108 purposively selected health workers in rural health facilities in the Eastern Cape province was conducted to assess knowledge on cervical cancer and associated risk factors through the use of validated structured questionnaires. The Statistical Package for Social Sciences was used for analysis, with a 95% confidence interval and a p-value of 0.05 considered significant. A total of 91.7% of the 108 participants were female, and 25% were over the age of 50. A total of 88% and 85.2% indicated sexually transmitted disease and human immunodeficiency virus as major risk factors, respectively. The HPV, pap smear, and vaccination age were known by 64.8%, and vaccine availability was known by 71.3%. Only 40.7% of workers were trained on cervical screening, and 35.2% were trained on the interpretation of pap smear results. An overall knowledge score of 53% was obtained, with more experienced clinicians scoring lower grades. This study identified inadequacies in essential knowledge for successful implementation of cervical cancer services and found that extensive training was needed.

Introduction/Objectives: Cervical cancer screening is a vital preventive strategy, yet the extent of healthcare workers’ knowledge, attitudes, and practices (KAP) can significantly influence its uptake, especially in rural settings. This study aimed to explore the knowledge, attitudes, and practices regarding cervical cancer screening among nurses in selected rural health facilities of the Eastern Cape province, South Africa. Methods: A cross-sectional, quantitative study was conducted among 108 nurses selected from 12 health facilities across two districts in the Eastern Cape. All participants had received some training on cervical cancer screening. Structured questionnaires were used to assess knowledge, attitudes, and practices. Comparisons between professional nurses (higher academic qualification) and enrolled nurses (lower academic qualification) were made using appropriate statistical tests. Results: Findings revealed significant disparities in knowledge and attitudes between professional and enrolled nurses. Professional nurses demonstrated significantly better knowledge and more positive attitudes towards cervical cancer screening than enrolled nurses, who showed inadequate knowledge (p = 0.021) and negative attitudes (p = 0.023). Despite universal training, the level of academic qualification remained a key factor influencing KAP. Conclusions: Academic qualification is closely linked to knowledge and attitudes regarding cervical cancer screening among nurses. Health workforce policies and programmatic initiatives should prioritize targeted training for enrolled nurses, focusing on addressing specific knowledge and skill gaps. Tailored interventions are recommended to enhance competencies and improve cervical cancer screening practices among all nursing cadres.

Assessing underlying illnesses can inform health stakeholders about chronic conditions for targeted enhanced prevention and treatment strategies. Since the Eastern Cape Province has a high disease burden, this study aimed to assess the prevalence of human immunodeficiency virus (HIV) infection and selected disease burden of outpatients from primary health care (PHC) facilities in the districts. From February 2019 to February 2021, a cross-sectional study was conducted. Research Electronic Data Capture (REDCap)-enabled tablets were used to collect data from consenting outpatients over the age of 18 years using an interviewer-administered WHO core and expanded stepwise questionnaire. The statistical analysis was mainly descriptive with the use of counts, frequencies, and summary measures. The study population was predominantly female (86.5%). Prevalent diseases included HIV, hepatitis B virus (HBV) infection, and cardiometabolic diseases. HIV prevalence was 52% and highest in the age group of 30–59 years. In people living with HIV, the nonsuppressed viral load (VL 1000 copies/mL) was highest in the age group of 40–49 years (34.6%). Prevalence of diabetes was highest at the Mhlontlo subdistrict (42.3%), while the King Sabata Dalindyebo (KSD) subdistrict had the highest prevalence of HBV infections (39.1%). Based on the findings, we advocate for intermittent assessments of disease burden in certain settings, such as rural areas, to improve PHC practice and outcomes, especially in the wake of the coronavirus disease (COVID-19) pandemic.

The prevalence of hypertension among people living with HIV (PLHIV) on antiretroviral therapy (ART) is concerning. Physical activity is a proposed approach for managing and avoiding hypertension in this population. While cardiorespiratory exercises (CET) have been efficacious in the general population, its effectiveness in PLHIV on ART, especially in the study setting, in Mthatha is unknown. Consequently, the purpose of this study was to see if CET improves cardiorespiratory fitness in HAART-treated PLHIV with blood flow restriction (BFR) in Mthatha, South Africa. A quasi-experimental study with 98 participants (49 of whom were cases) was carried out. Cases were participants assigned to the CET intervention group that comprised of concurrent training as it included both aerobic and resistance exercise, matched on age and gender. The relationship between CET and hypertension was assessed using logistic regression after adjusting for possible confounding variables. At baseline, there was no significant difference between the physical characteristics of the two groups, and after the intervention, there was a significant difference. Obesity and central adiposity were identified as strong risk factors for hypertension. The findings also indicated that a reduction in waist circumference and body mass index had a significant positive association with hypertension treatment amongst the intervention group (p < 0.05). According to the results of the study, CET has the potential to be an efficient and economical non-pharmacological intervention for the management and control of hypertension in PLHIV. However, further study is required to establish how long, how intense, and what kind of exercise is best for this population.
