We used an in vitro isotopic drug sensitivity assay to assess the sensitivity of Plasmodium falciparum isolates collected in Bangui, Central African Republic between March and July 2004. We tested antimalarials that are currently in use in this country (chloroquine, amodiaquine, quinine, and pyrimethamine), antimalarials that will become available in this region in the future (artemisinin and halofantrine), and prophylactic antimalarials (mefloquine, doxycycline, and atovaquone). The proportions of resistant isolates were 37% for chloroquine, 15.9% for amodiaquine, 0% for quinine, 0% for dihydroartemisinin, 1.6% for mefloquine, 3.8% for halofantrine, 4.0% for atovaquone, and 38.3% for pyrimethamine. No multi-resistant isolates (showing resistance to more than three drugs) were found. A positive correlation was found between the 50% inhibitory concentrations values for the following drugs: chloroquine and amodiaquine; quinine and halofantrine; chloroquine and dihydroartemisinin; chloroquine and halofantrine; amodiaquine and dihydroartemisinin; dihydroartemisinin and mefloquine; chloroquine and quinine; and quinine and dihydroartemisinin. These findings suggest that the Ministry of Health should recommend a interim policy with the amodiaquine plus sulfadoxine-pyrimethamine combination as the first-line antimalarial drug in Bangui until better alternative treatments such as artemisinin-based combination therapies become available at low prices in the Central African Republic.

Microvascular decompression: a contemporary update.
BMC Surg
January 2025
Department of Neurosurgery, Neurosurgery Clinic, Birgunj, Nepal.
Background: Microvascular decompression (MVD) is the gold-standard surgical treatment for cranial nerve compression disorders, including trigeminal neuralgia (TN), hemifacial spasm (HFS), and glossopharyngeal neuralgia (GPN). This review synthesizes historical milestones, recent advances, and evolving techniques in MVD, with a primary focus on these conditions.
Methods: A comprehensive literature review was conducted using databases such as PubMed, SpringerLink, Google Scholar, BioMed Central, Scopus, and ScienceDirect.
Provenance of late Pleistocene loess in central and eastern Europe: isotopic evidence for dominant local sediment sources.
Sci Rep
January 2025
Geochronology and Tracers Facility, British Geological Survey, Keyworth, Nottingham, NG12 5GG, UK.
Loess profiles along the Danube River provide a record of long-term Quaternary dust (loess) deposition in central-eastern Europe. Here, Sr-Nd isotopic data from four loess-palaeosol profiles (47 samples) spanning the last two-glacial-interglacial cycles are presented. The isotopic compositions generated by this study are compared with bedrock and sedimentary samples from Europe and North Africa to decipher the sources of sediment.

PLoS One
January 2025
Department of Preventive Medicine, School of Public Health, Addis Ababa University, Addis Ababa, Ethiopia.
Background: Despite the rising prevalence of common mental symptoms, information is scarce on how health workers make sense of symptoms of mental disorders and perceive a link with inadequate water, sanitation, and hygiene (WASH) as work stressors to understand causation and produce useful knowledge for policy and professionals. Therefore, this study aimed to explore how health workers perceive the link between inadequate WASH and common mental symptoms (CMSs) at hospitals in central and southern Ethiopian regions.
Methods: We used an interpretive and descriptive phenomenological design guided by theoretical frameworks.
Upper Arm Deep Vein Thrombosis in a Patient with Active Lupus.
Eur J Case Rep Intern Med
December 2024
Radiology Department, Seychelles Hospital, Healthcare Agency, Victoria, Seychelles.
Unlabelled: Upper extremity deep vein thrombosis (UEDVT) is relatively rare, and much less as an initial presentation of systemic lupus erythematosus (SLE). Primary UEDVT should be considered in individuals with unilateral arm swelling where the brachial, axillary, and subclavian veins are frequently involved. SLE is a chronic autoimmune disease that predominantly affects women of childbearing age and of African descent.

Département de Chimie, Université de Montréal, Montreal, QC, Canada. Electronic address:
This study investigated the occurrence of perfluoroalkyl and polyfluoroalkyl substances (PFAS), including anionic, cationic, and zwitterionic compounds, in drinking water. Between 2021-2023, an expanded list of 76 target PFAS was screened in tap water samples mainly from Canada, but also including tap water samples from the Eastern United States, Mexico, South America (Argentina), the Caribbean (Dominican Republic, Cuba), Africa (Algeria, Cameroon, Central African Republic, Morocco, Rwanda, Tunisia), Europe (France, Greece, Italy, Spain, and the United Kingdom) and Asia (Japan, Vietnam, Iran, and Türkiye). An additional ∼ 200 suspect-target PFAS were screened using high-resolution Orbitrap mass spectrometry.
