Objectives: To assess the accuracy and costs of laboratory tests in Kampala, Uganda.
Methods: A random selection of 78 laboratories tested external quality assurance samples at market rates. There were 40 moderate- to high-complexity and 38 low-complexity laboratories. Four percent (3/78) of these laboratories were accredited and 94% (73/78) were private. The 40 moderate- to high-complexity laboratories performed malaria blood smear, urine human chorionic gonadotropin (hCG), human immunodeficiency virus (HIV), syphilis, glucose, and three-panel tests: CBC, liver function tests, and kidney function tests. The 38 low-complexity laboratories performed malaria blood smear, urine hCG, and syphilis testing only. Hematology, HIV, syphilis, and malarial proficiency testing samples were prepared by accredited laboratories in Kampala. All other samples were provided by the Royal College of Pathologists of Australia.
Results: 77.1% of all results were accurate (met target values). It varied widely by laboratory (50%-100%), test identity (malaria blood smear, 96%; serum urea nitrogen, 38%), and test type (quantitative: 66% [31%-89%], qualitative: 91% [68%-97%]). Test prices varied by up to 3,600%, and there was no correlation between test cost and accuracy (r2 = 0.02).
Conclusions: There were large differences in accuracy and price across laboratories in Kampala. Price was not associated with quality.

Genome-wide association studies have identified approximately 200 genetic risk loci for breast cancer, but the causal variants and target genes are mostly unknown. We sought to fine-map all known breast cancer risk loci using genome-wide association study data from 172,737 female breast cancer cases and 242,009 controls of African, Asian and European ancestry. We identified 332 independent association signals for breast cancer risk, including 131 signals not reported previously, and for 50 of them, we narrowed the credible causal variants down to a single variant.

Article Synopsis
- This study focused on detecting Estrogen Receptor (ER), Progesterone Receptor (PR), and HER-2 in breast cancer to help categorize the disease and guide treatment choices.
- Researchers compared two preservation methods for breast tissue samples: traditional formalin fixation and RNAlater, utilizing Immunohistochemistry (IHC) and Quantitative Polymerase Chain Reaction (qPCR) for analysis.
- Findings revealed that ER and PR were positive in 60% of samples, while HER-2 was positive in only 25%, with no significant statistical difference between the results from the two preservation methods.
Global, regional, and national burden of primary liver cancer attributable to metabolic risks: an analysis of the Global Burden of Disease Study 1990-2021.

Background: The global burden of metabolic diseases is increasing, but estimates of their impact on primary liver cancer are uncertain. We aimed to assess the global burden of primary liver cancer attributable to metabolic risk factors, including high body mass index (BMI) and high fasting plasma glucose (FPG) levels, between 1990 and 2021.
Methods: The total number and age-standardized rates of deaths and disability-adjusted life years (DALYs) from primary liver cancer attributable to each metabolic risk factor were extracted from the Global Burden of Disease Study 1990-2021.

Antimicrobial resistance poses a global public health threat, compelling the search for alternative treatments, especially in resource-limited settings. The increasing ineffectiveness of traditional antibiotics has intensified the need to explore medicinal plants as viable therapeutic options. This study sought to compare the efficacy of certain medicinal plants used in Owerri, Nigeria, for treating pathogenic bacteria against traditional commercial antibiotics.
