Article Synopsis
  • Rheumatic and congenital heart diseases, along with cardiomyopathies and hypertensive heart disease, lead to significant health issues and fatalities in low- and lower middle-income countries (LLMICs), impacting the poorest populations.
  • Access to advanced cardiac care is limited, primarily concentrated in urban areas, creating a gap in healthcare for rural communities due to shortages of diagnostics, medications, and trained personnel.
  • The Package of Essential NCD Interventions - Plus (PEN-Plus) aims to improve access to cardiac care in these regions by decentralizing services, and a coalition of global cardiac organizations is collaborating to implement effective strategies for managing severe cardiac diseases in high-poverty settings.

Psychosocial challenges impact patients' ability to remain on antiretroviral therapy lifelong, magnified by disorganized health-systems and healthcare worker (HCW) attitudes. To address this, Médecins Sans Frontières and the Department of Health developed the Welcome Service intervention, to provide person-centered care at re-engagement after HIV treatment interruption. Implemented in Khayelitsha, South Africa, between August 2020 and February 2021, the intervention aimed to reorganize triage, optimize clinical and counselling services and address HCW attitudes.

Background: Children and adolescents with household exposure to multidrug- or rifampicin-resistant tuberculosis (MDR/RR-TB) are at high risk of developing TB disease. Tuberculosis preventive therapy (TPT) is recommended, but programmatic experience is limited, particularly for adolescents.

Methods: We conducted a prospective cohort study to describe MDR/RR-TB diagnosis and TPT provision for individuals aged <18 years with MDR/RR-TB exposure.

Background: Non-communicable diseases (NCDs) such as diabetes and hypertension have become a prominent public health concern in Malawi, where health care services for NCDs are generally restricted to urban centres and district hospitals, while the vast majority of Malawians live in rural settings. Whether similar quality of diabetes care can be delivered at health centres compared to hospitals is not known.

Methods: We implemented a pilot project of decentralized diabetes care at eight health centres in four districts in Malawi.

Daily oral pre-exposure prophylaxis (PrEP) is a key tool in addressing high HIV incidence among young women, and breaking the cycle of transmission. From 2017 to 2020, Médecins Sans Frontières (MSF) offered PrEP, in conjunction with contraception and risk-reduction counselling, to women aged 18-25, in a government-run clinic in Khayelitsha, a low income high HIV prevalence area in South Africa. Drawing on clinical, quantitative, and qualitative interview data, we describe participants' experiences and engagement with the PrEP program, participant adherence (measured by TFV-DP levels in dried blood spots) over time, and the indirect benefits of the PrEP program.

Background: The Alma-Ata Declaration's commitment to primary health care (PHC) reaches its 40th anniversary in 2018. Over the last 40 years, the number of non-governmental organisations (NGOs) working in low-income countries (LICs) has rapidly multiplied, and over time, NGOs have both positively and negatively impacted equity, effectiveness, appropriateness and efficiency of PHC systems in LICs.

Aim: The authors aim to demonstrate that at the 40th anniversary of the Alma-Ata Declaration's commitment to PHC, NGOs are particularly poised to strengthen PHC in LICs.

Background: Cardiovascular disease (CVD) risk among people living with HIV is elevated due to persistent inflammation, hypertension and diabetes comorbidity, lifestyle factors and exposure to antiretroviral therapy (ART). Data from Africa on how CVD risk affects morbidity and mortality among ART patients are lacking. We explored the effect of CVD risk factors and the Framingham Risk Score (FRS) on medium-term ART outcomes.

Background: Malawi has the highest rate of cervical cancer globally and cervical cancer is six to eight times more common in women with HIV. HIV programmes provide an ideal setting to integrate cervical cancer screening.

Methods: Tisungane HIV clinic at Zomba Central Hospital has around 3,700 adult women receiving treatment.

Background: Human immunodeficiency virus (HIV) programmes can be leveraged to manage the growing burden of non-communicable diseases (NCDs).

Methods: In October 2015, a model of integrated HIV-NCD care was developed at a large HIV clinic in southeast Malawi. Blood pressure was measured in adults at every visit and random blood glucose was determined every 2 y.

Objective: To describe available models of HIV and noncommunicable disease (NCD) care integration in sub-Saharan Africa (SSA).

Design: Narrative review of published articles describing various models of HIV and NCD care integration in SSA.

Results: We identified five models of care integration across various SSA countries.

Background: Many patients on antiretroviral therapy (ART) in Malawi have or will develop non-communicable diseases (NCDs). The current capacity of ART sites to provide care for NCDs is not known.

Aim: This study aimed to assess the capacity of ART sites to provide care for hypertension and diabetes in rural Malawi.

Background: Hypertension and diabetes prevalence is high in Africans. Data from HIV infected populations are limited, especially from Malawi. Integrating care for chronic non-communicable co-morbidities in well-established HIV services may provide benefit for patients by preventing multiple hospital visits but will increase the burden of care for busy HIV clinics.

Rates of abnormal visual inspection with acetic acid and prevalence of high-risk human papillomavirus (HPV) subtypes have not been well characterized in HIV-infected women in Malawi. We performed a prospective cohort study of visual inspection with acetic acid (N = 440) in HIV-infected women aged 25--59 years, with a nested study of HPV subtypes in first 300 women enrolled. Of 440 women screened, 9.
