Background. Hypertension (HPT) and its complications continue to pose a global threat and contribute to premature mortality worldwide. The adverse interactions between HPT, obesity and COVID-19 are currently being witnessed globally and represent a collision of pandemics. Understanding the burden that this non-communicable disease (NCD) poses in KwaZulu-Natal (KZN) Province, South Africa (SA), would help in developing improved public healthcare strategies.Objectives. To describe the burden of HPT in all the districts of KZN over a 6-year period.Methods. HPT data are routinely collected from all KZN public health facilities (both clinics and hospitals) as part of the District Health Information System (DHIS). In this retrospective study, we accessed HPT records from the DHIS over a period of 6 years (2014 - 2019, inclusive). Data collected included the number of patients screened, diagnosed and initiated on therapy for HPT, together with the number of obese patients.Results. The slopes for HPT screening were positive at both clinics and hospitals in KZN (considerably more at clinics than hospitals, with a difference in elevations of slopes of p<0.001), with a significantly greater percentage of the population having been screened at rural clinics than at hospitals (difference in elevation of slopes p<0.001). A significantly greater number of patients aged <40 years (p<0.001) were being screened for HPT at clinics than at hospitals (2017/18, 2018/19, 2019/20), while hospitals screened considerably more patients aged ≥40 years in 2017 - 2018 (p<0.001). The numbers of new hypertensives diagnosed and having treatment initiated were on an upward slope at both clinics and hospitals, with clinics having a greater elevation of slope than hospitals (p<0.001), irrespective of patient age. A significantly greater number of patients aged ≥40 years (p<0.05) were diagnosed with HPT at both clinics and hospitals in KZN (2017/18, 2018/19, 2019/20). KZN clinics remained the first port of call for known hypertensives throughout the study period. Obesity was prevalent at both clinic and hospital level, although figures were significantly higher at clinics. Over 80% of the obesity burden was carried by the rural clinics and hospitals.Conclusions. Screening, diagnosis, treatment initiation and chronic management of HPT occur mainly at rural clinic level. The SA government needs to heed these findings and redirect resources (staffing and equipment) to this level. The prevalence of obesity was highest at rural healthcare facilities (clinics more than hospitals). More needs to be done to combat the obesity pandemic if we are to win the battle against NCDs (HPT and diabetes mellitus). A significant number of patients aged <40 years are being screened for HPT, which bodes well for the province, as early diagnosis and treatment of HPT are vital to prevent complications.

Background. The South African (SA) government introduced Implanon NXT, a long-acting subdermal contraceptive implant, in 2014 to expand contraceptive choice. Following an initial high uptake, its use declined considerably amid reports of early removals and frequent side-effects. We examine providers' perceptions of training and attitudes towards Implanon NXT, as well as their views on the causes of early removals and the impact on the implant service. Objective. To assess healthcare providers' perceptions and attitudes towards implant services in SA. Methods. In-depth interviews were conducted with eight nurses providing implant services in public facilities in Gauteng and North West Province. Emerging themes were identified, manually coded and thematically analysed following an interpretivism approach. Results. Nurses lacked confidence in providing implant services effectively, particularly removals, which they ascribed to the brief, cascade-type training received. Nurses generally held negative views towards the method. They also reported that side-effects are the most common reason for early removals – particularly irregular bleeding – and that men often do not support their partners who use the method. Lastly, it was found that providers require guidance on counselling regarding the method and standardised guidelines on the management of side-effects. Conclusion. Retraining and support of providers are needed to address competency gaps and negative attitudes towards the method. Assessment of providers' readiness to perform removal procedures is also important. Finally, effective plans are necessary to improve implant continuation rates, especially among women whose partners are unsupportive.S Afr Med J 2017;107(10):822-826

BACKGROUND: Limited engagement in clinic-based care is affecting the HIV response. We explored the field experiences and perceptions of local health care workers regarding home-based strategies as opportunities to improve the cascade of care of people living with HIV in rural South Africa as part of a Universal Test-and-Treat approach. METHODS: In Hlabisa sub-district, home-based HIV services, including rapid HIV testing and counselling, and support for linkage to and retention in clinic-based HIV care, were implemented by health care workers within the ANRS 12249 Treatment-as-Prevention (TasP) trial. From April to July 2016, we conducted a mixed-methods study among health care workers from the TasP trial and from local government clinics, using self-administrated questionnaires (n = 90 in the TasP trial, n = 56 in government clinics), semi-structured interviews (n = 13 in the TasP trial, n = 5 in government clinics) and three focus group discussions (n = 6-10 health care workers of the TasP trial per group). Descriptive statistics were used for quantitative data and qualitative data were analysed thematically. RESULTS: More than 90% of health care workers assessed home-based testing and support for linkage to care as feasible and acceptable by the population they serve. Many health care workers underlined how home visits could facilitate reaching people who had slipped through the cracks of the clinic-based health care system and encourage them to successfully access care. Health care workers however expressed concerns about the ability of home-based services to answer the HIV care needs of all community members, including people working outside their home during the day or those who fear HIV-related stigmatization. Overall, health care workers encouraged policy-makers to more formally integrate home-based services in the local health system. They promoted reshaping the disease-specific and care-oriented services towards more comprehensive goals. CONCLUSION: Because home-based services allow identification of ...

Purpose of the studyVirological outcomes and resistance patterns in children initiating protease inhibitor (PI)‐based antiretroviral therapy (ART) immediately following HIV‐1 diagnosis are not well described. Challenges include maintaining adherence in asymptomatic patients with very high pre‐ART viral loads. The CHER trial compared deferred but continuous ART (arm 1) with early limited ART (arms 2 and 3).MethodsLPV/r+ZDV+3TC was commenced either immediately (in 250 of 252 children randomized in arms 2 and 3) or at clinical/immunological progression (103 of 125 children in arm 1). Interruption of ART occurred after 40 (arm 2) or 96 weeks (arm 3) and re‐initiation with LPV/r + ZDV + 3TC was based on immunologic/clinical criteria. Viral load was measured on all children with a stored specimen at their last visit, having been on initial or restarted ART following interruption (arms 2 and 3) for at least 24 weeks. Children in arms 1, 2 and 3 not initiating ART due to death (16, 0, 0), LTFU (2, 2, 0) or other reason (4, 0, 0) are excluded. Resistance testing was performed on samples with a viral load (VL) ≥1000 c/mL together with the matched baseline sample, if available. Reverse transcriptase (NRTI and NNRTI) and PI inhibitor mutations were analyzed using a validated in‐house population‐based sequencing assay and the IAS 2011 mutation list.Summary of resultsA total of 377 infants were enrolled; median was age 7.4 (interquartile range (IQR) 6.7 to 8.9) weeks and median baseline viral load was log10 5.7. By end of study (June 2011), 353/377 children had started LPV/r + ZDV + 3TC. Median (IQR) age at ART initiation in arms 1, 2 and 3 was 26.1 (19.9 to 40), 7.4 (6.6 to 8.7) and 7.5 (6.6 to 9.0) weeks. Median (IQR) duration on ART was 240 (216 to 252), 243 (200 to 260) and 240 (194 to 257) weeks in arms 1, 2 and 3, respectively. HIV‐1 RNA was <400 c/mL in 88/101 (87%), 95/113 (84%) and 97/117 (83%) (P=0.96). Twenty‐two of thirty‐two children with VL >1000 c/mL (2/5, 8/14, 12/13 in arms 1, 2 and 3) have had resistance tests to date; nine (41%) had mutations. There were seven with M184V mutations (1, 4, 2 in arms 1, 2 and 3); two with major PI mutations (V82A/L76V) (one in each of arms 1 and 2); and two with major NNRTI mutations (K103N/M230L) (one in each of arms 2 and 3). Two of ten children tested to date had NNRTI mutations prior to starting PI‐based triple therapy.ConclusionsVirological response on ART was excellent in this large cohort of infants initiating LPV/r+ZDV+3TC at a very young age, with no differences between randomized strategies, suggesting that planned interruption after early limited ART does not adversely affect virological outcomes. Overall, approximately 40% of those on ART with VL>1000 c/mL had a resistance mutation; PI mutations were infrequent, despite around 5 years on therapy. Ongoing work will investigate impact of length of time with detectable viral load on risk of developing resistance.
