Background: There are limited South African data on the outcomes of patients with severe malaria treated with quinine compared with those treated with artesunate in the intensive care unit (ICU). Objectives: To compare the outcomes of adult patients treated with artesunate against those treated with quinine in the ICU. Primary outcome variables are length of stay (LOS) in the ICU and mortality. Secondary outcomes include the incidence of hypoglycaemic episodes and neurological outcomes. Methods: This was a retrospective cohort study of patients with severe malaria treated at a multidisciplinary ICU with artesunate or quinine from 1 January 2008 to 31 December 2012. Results: Of the 92 patients included in the study, 63 (69.2%) were male. The mean age in the quinine and artesunate groups was 36.2 years and 40.5 years, respectively (p=0.071). Most (98.6%) of the patients with a positive travel history had visited a malaria-endemic region. Of the 53 patients tested for HIV infection, 71.7% tested positive (p=0.520). The average CD4+ cell count of HIV-positive patients treated with quinine was 200 cells/µL compared with 217.17 cells/µL for those treated with artesunate (p=0.875). The mean APACHE II score at admission was 20.85 and 19.62 in the quinine group and artesunate group, respectively (p=0.380). The median LOS was 5 days (range 1 - 27). Mortality was 15.4% in the quinine group and 7.7% in the artesunate group (p=0.246). Conclusion: A statistically insignificant mortality difference was observed in outcomes of the two treatment groups in this retrospective, single-centre cohort study. Contributions of the study: Intravenous artesunate is currently the preferred treatment in the management of patients with severe malaria. However, there are limited local data on the outcomes of artesunate v. quinine therapy for the management of severe malaria in highly monitored clinical environments in non-endemic regions of South Africa.We describe clinical characteristics, management and outcomes of patients with severe malaria treated with quinine and those treated with artesunate in the ICU in a non-endemic region.

BACKGROUND: Breast cancer survival rates in sub-Saharan Africa are low. In a prospective, multi-center cohort study, we estimated 5-year overall survival rates, overall survival determinants, and mediating effects between socioeconomic status on overall survival among South African women diagnosed with invasive BC. PATIENTS AND METHODS: Patients from 4 public hospitals were enrolled between July 1, 2015 and January 31, 2019. Survival determinants were assessed using Cox proportional hazard models adjusted for age, background mortality, and treatments. Socioeconomic pathway effects on overall survival were determined through generalized structural equation models. RESULTS: Of 2838 participants, 58% had advanced-stage (III/IV) disease. Five-year crude overall survival was 44.3% (95% CI 42.5-46.2). Significant mortality risks were late stage at diagnosis (hazard ratio [HR] = 2.31 [95% CI 1.99-2.69] [stage III]; 4.79 [95% CI 3.96-5.80] [stage IV]), HIV-positive status (HR = 1.45 [95% CI 1.25-1.67]), unemployment HR = 1.25 [95% CI 1.09-1.44], and low education HR 1.19 [95% CI 1.04-1.37]). Age and treatment-adjusted socioeconomic status effects on overall survival were mediated through HIV status (81.7% of the effect) and stage at diagnosis (81.7%), both P < .001. Poor breast cancer knowledge had an indirect effect on overall survival, accounting for 77.6% of the total effect (P = .001), fully mediated by late-stage presentation. Socioeconomic status had no significant direct path to mortality after accounting for these mediators. CONCLUSION: Interventions should prioritize early breast cancer detection. For patients with low socioeconomic status, particularly those with comorbid HIV, we must mitigate multifaceted barriers to healthcare access, including limited awareness and knowledge of breast cancer.

Abstract Background Cancer patients in Sub-Saharan Africa (SSA) are diagnosed late partly due to community lack of knowledge about the disease, social and cultural factors, health system challenges, and inadequate health care worker knowledge. These delays in diagnosis as well as inadequate treatment options contribute to the high mortality from lung cancer in SSA. Quality of life (QoL) is an important outcome measure for cancer patients undergoing treatment. Objective To describe the quality of life among lung cancer patients in three teaching hospitals in SSA. Methods This is a prospective cross-sectional study of lung cancer patients at three teaching hospitals in Sub-Saharan Africa (SSA-Kenya (BMC), Tanzania (MTRH) and South Africa (The Lung Laboratory Research and Intervention Unit Helen Joseph Hospital). Trained interviewers collected data on demographics, clinical information and performance status using the Eastern Cooperative Oncological Group Performance Scale (ECOG-PS). Patients’ QoL was assessed using the 30-item European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Results A total of 210 lung cancer patients consented and were enrolled across the three sites. Global Health Status in this cohort is low, the median score was 41.7 (range: 0-100) and differed between sites. Wits Core patients had higher social functioning, while BMC and MTRH had higher financial difficulty scores. Poor ECOG-PS score (3-4) was associated with poorer Global QoL (GqoL) score (aOR = 2.9; 95% CI: 1.4 - 5.9), and patients with higher symptom burden had poorer GQoL. Conclusion The QoL among lung cancer patients in the three sites is low. Poor QOL in the study is associated with level of education, performance status, fatigue, pain, dyspnoea, insomnia, loss of appetite and constipation.
