Perception and experience of clinicians and caregivers in treating childhood severe pneumonia and hypoxemia using bubble continuous positive airway pressure in Ethiopian tertiary and general hospitals.

Background: In low and middle-income countries (LMICs), severe pneumonia with hypoxemia is the leading cause of child deaths, even with the provision of WHO-recommended antibiotic therapy, oxygen therapy and other supportive care. Previous studies found positive outcomes from the use of bubble continuous positive airway pressure (bCPAP) for treating these children compared to the standard oxygen therapy. Due to lack of data on the perceptions and experiences of hospital health care workers and caregivers of children on the feasibility and acceptability of bCPAP in treating children with severe pneumonia and hypoxemia in real-life settings, we examined these issues in tertiary and general hospitals in Ethiopia.

High seroprevalence of anti-SARS-CoV-2 antibodies among Ethiopian healthcare workers.

Background: COVID-19 pandemic has a devastating impact on the economies and health care system of sub-Saharan Africa. Healthcare workers (HWs), the main actors of the health system, are at higher risk because of their occupation. Serology-based estimates of SARS-CoV-2 infection among HWs represent a measure of HWs' exposure to the virus and could be used as a guide to the prevalence of SARS-CoV-2 in the community and valuable in combating COVID-19.

Prevalence of asymptomatic visceral leishmaniasis in human and dog, Benishangul Gumuz regional state, Western Ethiopia.

Background: The Benishangul-Gumuz region is an important development corridor in Ethiopia. Large-scale projects such as the Great Renaissance Dam, mining and agriculture have entailed huge environmental modifications and settlement pattern changes. There is no detailed epidemiological information on visceral leishmaniasis (VL) in the region.

Field evaluation of FD-DAT, rK39 dipstick and KATEX (urine latex agglutination) for diagnosis of visceral leishmaniasis in northwest Ethiopia.

Three novel diagnostic tests for visceral leishmaniasis (VL), namely FD-DAT, rK39 dipstick and KATEX, were evaluated under field conditions using 101 clinical cases suspected of having VL enrolled in a trial either by active (63 patients) or passive (38 patients) surveillance. VL was confirmed in 49 patients: 35 by both aspirate smear microscopy and NNN culture, 10 by NNN culture alone and 4 by aspirate smear microscopy alone. Based on tests performed in the field, sensitivity for FD-DAT, rK39 dipstick and KATEX was determined to be 95.

Leishmania aethiopica: identification and characterization of cathepsin L-like cysteine protease genes.

There is limited information on the biology and pathogenesis of Leishmania aethiopica, causative agent of cutaneous leishmaniasis (CL) in Ethiopia. In this study we have identified and characterized two cathepsin L-like cysteine protease genes, Laecpa and Laecpb, from L. aethiopica.

Identification, sequencing and expression of peroxidoxin genes from Leishmania aethiopica.

Cutaneous leishmaniasis (CL) is a painful, disfiguring and debilitating disease prevalent in Ethiopia and other countries around the world. In Ethiopia, CL is primarily caused by Leishmania aethiopica and less often by L. tropica and L.

Leishmania aethiopica: strain identification and characterization of superoxide dismutase-B genes.

This study was performed to characterize the genes that code for superoxide dismutase (SOD) in Leishmania aethiopica. It involved three main steps: specimen collection and parasite isolation, species identification, and molecular characterization of the SOD genes. Out of 20 skin slit specimens cultured and processed from suspected cutaneous leishmaniasis patients enrolled in the study, five (25%) were found to be positive for motile promastigotes.

A community based study of urogenital chlamydia trachomatis in males aged fifteen years and above, Dembia District, northwest Ethiopia.

Chlamydia trachomatis is one of the most common causes of sexually transmitted diseases in sexually active males and females. Infertility is one of the serious complications of urogenital chlamydial infections. This study was carried out in Chuwahit town and the surrounding village, which is located southwest of Gondar town.
