Abstract Background : Cryptococcosis is an opportunistic fungal infection that primarily affects people with advanced Human immunodeficiency virus (HIV) disease and is an important cause of morbidity and mortality around the globe. By far the most common presentation of the disease is cryptococcal meningitis (CM), which leads to an estimated 15-20% of all HIV related deaths worldwide, 3/4 of which are in sub-Saharan Africa. However, to the best of our knowledge there is quite limited reviewed data that on the epidemiology of cryptococcal antigenemia in a large HIV-infected population in resource limited settings. Methods : Articles published in English irrespective of the time of publication were systematically searched using comprehensive search strings from PubMed/Medline and SCOPUS. In addition, Google Scholar and Google databases were searched manually for grey literature. Two reviewers independently assessed study eligibility, extracted data, and assessed risk of bias. The magnitude of cryptococcal antigenemia and its predictors were presented with descriptive statistics and summary measures. The pooled prevalence of cryptococcal antigenemia was also determined with 95% confidence interval (CI). Result: A mong 2941 potential citations, we have included 22 studies with a total of 8,338 HIV positive individuals. The studies were reported in ten different countries during the year (2007-2018). Most of the articles reported the mean CD4 count of the participants <100 cells/µl. The pooled prevalence of cryptococcal antigenemia at different CD4 count and ART status was at 8% (95%CI: 6-10%) (ranged between 1.7% and 33%). Body mass index (BMI) <18.5kg/m 2 , CD4 count <100 cells, presenting with headache and male gender were reported by two or more articles as an important predictors of cryptococcal antigenemia. Conclusions : Implementing a targeted screening of HIV patients with low BMI, CD4 count <100 cells, having headache and males; and treatment for asymptomatic cryptococcal disease should be considered. Additional data is needed to better define the epidemiology of cryptococcal antigenemia and its predictors in resource limited settings in order to design prevention, diagnosis, and treatment strategies.

Purpose Low- and middle-income countries disproportionately comprise 65% of cancer deaths. Cancer care delivery in resource-limited settings, especially low-income countries in sub-Saharan Africa, is exceedingly complex, requiring multiple modalities of diagnosis and treatment. Given the vast human, technical, and financial resources required, access to radiotherapy remains limited in sub-Saharan Africa. Through 2017, Rwanda has not had in-country radiotherapy services. The aim of this study was to describe the implementation and early outcomes of the radiotherapy referral program at the Butaro Cancer Centre of Excellence and to identify both successful pathways and barriers to care. Methods Butaro District Hospital is located in a rural area of the Northern Province and is home to the Butaro Cancer Centre of Excellence. We performed a retrospective study from routinely collected data of all patients with a diagnosis of cervical, head and neck, or rectal cancer between July 2012 and June 2015. Results Between 2012 and 2015, 580 patients were identified with these diagnoses and were potential candidates for radiation. Two hundred eight (36%) were referred for radiotherapy treatment in Uganda. Of those referred, 160 (77%) had cervical cancer, 31 (15%) had head and neck cancer, and 17 (8%) had rectal cancer. At the time of data collection, 101 radiotherapy patients (49%) were alive and had completed treatment with no evidence of recurrence, 11 (5%) were alive and continuing treatment, and 12 (6%) were alive and had completed treatment with evidence of recurrence. Conclusion This study demonstrates the feasibility of a rural cancer facility to successfully conduct out-of-country radiotherapy referrals with promising early outcomes. The results of this study also highlight the many challenges and lessons learned in providing comprehensive cancer care in resource-limited settings.

Globally, the COVID-19 pandemic has aggravated inequalities in access to quality pharmacy education, particularly in resource-limited settings in Africa (Engle, 2020; Fuller et al., 2020). This is a serious concern for Africa especially, given that sub-Saharan Africa ranks lowest on the global pharmaceutical workforce index and has a disproportionately high burden of infectious and non-communicable diseases, combined with weak health systems (World Health Organisation [WHO], 2013; Bates et al., 2018).
