Objective The global incidence and burden of Major Depressive Disorder (MDD) are increasing annually, with current antidepressant treatments proving ineffective for 30-40% of patients. Biomolecular mechanisms within the microbiota-gut-brain axis (MGBA) may significantly contribute to MDD, potentially paving the way for novel treatment approaches. H...

Adolescent depression is a heterogenous disorder, with a wide variety of symptoms and inconsistent treatment response, and is not completely understood. A dysregulated stress system is a consistent finding, however, and exhaustion is a consistent trait in adolescent patients. The aim of this paper is to critically assess current hypotheses in adole...

1 Introduction Internationally validated tools to measure patient‐reported health‐related quality of life (HRQoL) are available, but efforts to translate and culturally validate such tools in sub‐Saharan Africa (SSA) are scarce, particularly among children. 2 Methods The Patient‐Reported Outcomes Measurement Information System 25‐item pediatric sh...

Eight Dutch hospital pharmacies took wipe samples of prepared infusion bags containing 5 fluorouracil just before distribution to the wards. The samples were tested with high-performance liquid chromatography and triple quadrupole mass spectroscopy. The limit of detection was 10 ng per swipe. None of the 146 samples had a detectable amount of 5-flu...
Article
To the Editor In their Original Investigation published in a recent issue of JAMA Internal Medicine, Prasad and Mailankody¹ examine the costs of bringing a single drug with an oncological indication to the market. They conclude that 10 selected companies had a median investment cost of $648 million for the development of their drug, whereas the med...

Purpose: Lymphoma is the commonest pediatric cancer in sub-Saharan Africa (SSA). Frequent treatment abandonment contributes to suboptimal outcomes. We examined risk factors and reasons for treatment abandonment for this population in Malawi. Methods: We conducted a mixed methods study among children < 18 years old with newly diagnosed lymphoma,...
Article
Full-text available
Background Lymphoma is highly associated with HIV in sub-Saharan Africa (SSA), which contributes to worse outcomes relative to resource-rich settings, and frequent failure of first-line chemotherapy. However, there are no second-line treatment descriptions for adults with relapsed or refractory lymphoma (RRL) in SSA. Methods We describe HIV+ and H...
Article
Full-text available
Background Extranodal NK/T-cell lymphoma (ENKTCL) reports from sub-Saharan Africa (SSA) are remarkably rare, despite early childhood acquisition and high prevalence of the causative infectious agent, Epstein-Barr virus (EBV), and frequent occurrence of other lymphoproliferative disorders causally associated with EBV. Case presentations At a nation...

Context Recent public outcry has highlighted the rising cost of prescription drugs worldwide, which in several disease areas outpaces other health care expenditures and results in a suboptimal global availability of essential medicines. Method A systematic review of Pubmed, the Financial Times, the New York Times, the Wall Street Journal and the G...

Article
Background: Given scarce data from sub-Saharan Africa (SSA), we sought to describe CD4 count and HIV RNA trends over time among patients with HIV+ lymphoproliferative disorders in Malawi. Methods: We prospectively enrolled HIV+ individuals with pathologically confirmed lymphoproliferative disorders between 2013 and 2016. Chemotherapy was standar...
Article
Point-of-care tools are needed in sub-Saharan Africa (SSA) to improve pediatric Burkitt lymphoma (BL) diagnosis and treatment. We evaluated plasma Epstein-Barr virus (pEBV) DNA as a pediatric BL biomarker in Malawi. Prospectively enrolled children with BL were compared to classical Hodgkin lymphoma (cHL) and non-lymphoma diagnoses. Pediatric BL pat...
Article
Introduction: The global distribution of sickle cell disease (SCD) overlaps with that of food scarcity and nutritional deficiencies. Chronic anemia secondary to SCD contributes to nutritional deficiencies, for example folic acid. Few studies have evaluated associations between malnutrition and SCD, nor effects of malnutrition on SCD outcomes. Moreo...
Article
Pediatric lymphoma is common in sub-Saharan Africa, where survival estimates are often based on limited follow-up with incomplete retention, introducing potential for bias. We compared follow-up and overall survival (OS) between passive and active tracing within a prospective cohort of children with lymphoma in Malawi. Median follow-up times were 4...
Article
Introduction: Rhenium-188-HEDP ((188)Re-HEDP) is a therapeutic radiopharmaceutical for treatment of osteoblastic bone metastases. No standard procedure for the preparation of this radiopharmaceutical is available. Preparation conditions may influence the quality and in vivo behaviour of this product. In this study we investigate the effect of crit...
Article
The binding of some novel bicalutamide analogues to human serum albumin (HSA) and rat serum albumin (RSA) was investigated by surface plasmon resonance (SPR) based optical biosensor technique. The serum protein binding of the bicalutamide analogues was determined and compared to that of the parent compound. Furthermore, HSA and RSA were used as tar...

Background: With the increased knowledge of biological risk factors, interest in including this information in forensic assessments is growing. Currently, forensic assessments are predominantly focused on psychosocial factors. A better understanding of the neurobiology of violent criminal behaviour and biological risk factors could improve forensi...

The possibility of gene doping, defined as the transfer of nucleic acid sequences and/or the use of normal or genetically modified cells to enhance sport performance, is a real concern in sports medicine. The abuse of knowledge and techniques gained in the area of gene therapy is a form of doping, and is prohibited for competitive athletes. As yet...
