Spatially Dissecting Drivers Of Inter-And Intra-Tumoral Heterogeneity In Kenyan Breast Cancer, Mustapha Abubakar, Shahin Sayed, Hela Koka, Scott Lawrence, Karun Mutreja, Xing Hua, Petra Lenz, Samuel Anyaso-Samuel, Rosemary Kamau, Beryl Ooro

Pathology, East Africa

Despite growing evidence on the impact of intra-tumoral heterogeneity (ITH) in breast cancer (BC), its biological drivers and clinically relevant mitigation strategies remain poorly characterized, particularly in low-resource settings where spatial profiling is rarely applied. To address this gap, we conducted a comprehensive, multiplatform spatial profiling study of BC in a Kenyan population. Using the NanoString GeoMx™ Digital Spatial Profiler, we quantified 44 protein markers across 707 spatially defined, PanCK-segmented Areas of Illumination (AOIs) from 31 tumors. All tumors exhibited measurable ITH, with one-third showing marked heterogeneity. Sixteen patients exhibited two or more intrinsic subtypes within their tumors, three of …

Unlocking The Potential Of Sub-Saharan Africa In Globalized Cancer Clinical Trials: A Perspective From The 2024 Aortic-Asco Stakeholder Meeting, Abiola Ibraheem, Adedayo Joseph, Miriam Mutebi, Mansoor Saleh, Sitna Mwanzi, Olusegun Alatise

General Surgery, East Africa

Sub-Saharan Africa (SSA) remains significantly underrepresented in global cancer clinical trials, despite having the largest population of individuals of African descent, an essential demographic for ensuring diversity in clinical research. This study, developed from the 2024 African Organization for Research and Training in Cancer (AORTIC)-ASCO stakeholder meeting, addresses the critical need to involve SSA in cancer trials to improve global trial diversity and patient outcomes. Although globalization of trials has shifted research sites to regions like Eastern Europe and Asia, < 1% occur in Africa. This report highlights emerging solutions such as regional alliances, decentralized trial models, capacity-building initiatives, and public-private partnerships. The role of AORTIC and its Clinical Trial Special Interest Group in advancing training, infrastructure development, and international collaboration is discussed, with notable clinical trial networks, such as HypoAfrica, ARETTA, African Research Group for Oncology, and regional consortia, illustrating growing momentum and capability. This study advocates for a coordinated strategy to integrate SSA into global trials, ensuring more inclusive, effective, and equitable cancer treatment outcomes.

Assessing Aflatoxin Knowledge, Perceptions, And Related Practices, In A Rural Coastal Community: A Population-Based Cross-Sectional Survey, Rosebella Iseme, Joseph Abuodha, Anthony Ngugi, Innocent Abayo, Mansoor Saleh

Population Health, East Africa

Background

Aflatoxin contamination is a significant yet under-addressed food safety challenge in low-resource settings, driven by a complex interplay of environmental, agricultural, and socio-economic factors. Limited access to agricultural inputs, inadequate post-harvest handling and storage, and weak regulatory enforcement alongside food scarcity and climate change heighten the risk of contamination and exposure. Human exposure is associated with serious health consequences, including hepatocellular carcinoma, immune suppression, and childhood stunting. Although aflatoxin is increasingly recognized as a global food safety concern, little is known about community-level knowledge, risk perceptions, and preventive practices. This study examined household heads’ awareness, perceptions, and behaviours related …

In a cohort of 440 Ugandan children hospitalized with severe malaria who were diagnosed with Plasmodium species via microscopy, nested polymerase chain reaction (nPCR) testing was used to detect P. falciparum, Plasmodium ovale (P. ovale), Plasmodium malariae (P. malariae), and Plasmodium vivax (P. vivax) infections and assess their association with adverse clinical outcomes during hospitalization. Using nPCR testing, the Plasmodium 18S small-subunit ribosomal RNA gene was detected in 440 children. Plasmodium falciparum mono-infection was identified in 329 (74.8%) …

The Influence Of Older Age On Rbc Transfusion Decisions In Icu Patients, Caroline Schaap, Jorinde Raasveld, Florian Reizine, Boillot Corentin, Jimmy Schenk, Sanne De Bruin, Merijn Reuland, Claudia Van Den Oord,, Andrew Flint, Marcus Lance

Anaesthesiology, East Africa

Objectives: RBC transfusions are common in the ICU. Recent studies suggest that a restrictive transfusion policy is noninferior or superior to a liberal policy. However, few studies focus on the influence of age in transfusion. In elderly ICU patients, reduced physiologic reserves may shift the perceived risk-benefit balance of transfusion, potentially leading to different transfusion practices. This study examines whether transfusion practices in ICU patients differ across patient age.

Design: This is a substudy of the International Point Prevalence Study of ICU Transfusion Practices (InPUT), a global, multicenter, prospective observational cohort study.

Setting: ICUs from 233 centers …

A Review Of Yellow Fever: Epidemiology, Pathogenesis, Clinical Manifestations, Treatment, Prevention, And Prognosis, Farah Ebrahim, Samina Somji, Reena Shah, Salim Surani

Internal Medicine, East Africa

Yellow fever is a mosquito-borne viral illness caused by the yellow fever virus (YFV), a member of the Flaviviridae family. Despite the availability of an effective live-attenuated vaccine, the disease remains endemic in regions of Africa and South America. Transmission occurs primarily via an infected mosquito called Aedes aegypti, with distinct urban, sylvatic, and intermediate transmission cycles. Clinically, infection ranges from mild febrile illness to severe disease, which is characterized by jaundice, hemorrhage, and multiorgan failure. Pathogenesis involves viral replication in hepatocytes, immune-mediated injury, and dysregulated inflammatory responses, leading to characteristic hepatic mid-zone necrosis. Diagnosis relies on molecular detection …
