Background: While breast cancer incidence rates in Sub-Saharan Africa (SSA) are among the lowest worldwide, mortality rates remain among the highest, reflecting particularly poor survival. Only a few studies in SSA have investigated the capabilities of treatment services to adequately provide a continuum of care for breast cancer. Our aim was to assess the availability of diagnostic facilities and adjuvant therapies in hospitals performing breast cancer surgery in SSA.

Background: Cardiac disease (CD) is a primary long-term diagnosed pathology among childhood cancer survivors. Dosiomics (radiomics extracted from the dose distribution) have received attention in the past few years to assess better the induced risk of radiotherapy (RT) than standard dosimetric features such as dose-volume indicators. Hence, using the spatial information contained in the dosiomics features with machine learning methods may improve the prediction of CD.

Post-hoc comparison procedures are commonly used to determine which group means differ after a significant analysis of variance (ANOVA). Several post-hoc tests have been proposed, but their use requires certain assumptions to be met, such as normality, equality of variance, and balanced group size. This review examined the statistical literature on post-hoc tests and their use in the environmental and biological sciences.

November 2024

Ageing, Cancer, and Disparities Research Unit, Department of Precision Health, Luxembourg Institute of Health, 1A-B, rue Thomas Edison, Strassen 1445, Luxembourg. Electronic address:

Background: The global population aged 80 years or older is expected to triple by 2050, leading to an increased cancer burden in the oldest population. This study describes the estimated cancer incidence and mortality in 2022 and projections for 2050 in the oldest old, analyzed globally and by world regions and World Bank income levels, for all sexes combined, as well as separately for males and females.

Methods: Using GLOBOCAN 2022 estimates, we reported the estimated number of new cancer cases (excluding non-melanoma skin cancers), deaths, and truncated age-standardized incidence (ASIR) and mortality rates (ASMR) (per 100,000 individuals aged 80 years or older).

Predicting the distribution, structure, and biomass of mangrove forests is an area of high research interest. Across the Atlantic East Pacific biogeographic region, three species are common and abundant members of local mangrove communities; , , and . Biomass prediction for these species has relied on two approaches: site-specific allometries based on the idea that environmental/climatic differences between sites drive growth differences, or the use of common allometric equations based on the idea that site driven differences are minimal.

This study aimed to understand feeding strategies used by small ruminant farmers to cope with climatic change in the five contrasting agroecological zones (AEZ) of the Benin Republic and to identify the determinants of adopting these strategies. A semi-structured questionnaire was used to conduct interviews with 400 smallholder farmers in the rural areas of Benin. Data was collected on production system characteristics, farmers' perception of climatic changes' impacts on livestock production, and their coping strategies.

Global health has traditionally focused on the primary health development with disease-specific focus such as HIV, malaria and non-communicable diseases (NCDs). As such, surgery has traditionally been neglected in global health as investment in them is often expensive, relative to these other priorities. Therefore, efforts to improve surgical care have remained on the periphery of initiatives in health system strengthening.
