Preferred techniques of hair harvest for medical testing among adult pulmonary TB patients

Background: Antiretroviral hair drug levels are currently being used to monitor adherence to HIV treatment. There is currently a dearth of literature on the preferred technique(s) of hair harvest for medical testing in the context of African multicultural settings. Objective: To explore the preferred techniques(s) of hair harvest for medical testing among TB patients. Methods: We used a descriptive phenomenological approach to conduct interviews for 15 TB patients from the 06th through the 24th of June 2022. Data was organized by N-VIVO version 10 and analysed step by step using a thematic analytical approach. Results: Participants aged <30 years were more knowledgeable, positively perceived, and experienced about the salon-based hair cutting technique compared to those aged≥30 years old. Participants aged ≥30 had experience, flexibility to use, and were knowledgeable in all three techniques, Overall, for all age categories (<30,30-40 and >40 years), majority of the respondents were knowledgeable, flexible and experienced in using all the three techniques. Conclusion: The majority of TB patients were knowledgeable, experienced and flexible about the hair cutting techniques however, efforts are needed to educate the youth that hair for medical testing can be cut by any of the three techniques without changing their cosmetic look.

Aspergillus-specific IgM/IgG antibody serostatus of patients hospitalized with moderate-critical COVID-19 in Uganda

Invasive pulmonary aspergillosis is known to complicate the coronavirus diseases-2019 (COVID-19), especially those with critical illness. We investigated the baseline anti Aspergillus antibody serostatus of patients with moderate-critical COVID-19 hospitalized at 3 COVID-19 Treatment Units in Uganda. All 46 tested patients, mean age 30, and 11% with underlying respiratory disease had a negative serum anti-Aspergillus IgM/IgG antibody immunochromatographic test on day 3 (mean) of symptom onset (range 1-26), but follow up specimens to assess seroconversion were not available

Prevalence of Virulence Determinants in Staphylococcus Epidermidis from ICU Patients in Kampala; Uganda

Introduction: Staphylococcus epidermidis is often considered a non-pathogenic organism but it causes nosocomial infections. To distinguish invasive strains; comparative studies of patient and community isolates may offer some clues. We investigated the distribution of virulence determinants in patient isolates from Uganda. Methodology: S. epidermidis isolates were identified with the Staph API ID 32 kit. Antimicrobial susceptibility; biofilm formation and hemolysis were detected with standard procedures. Genes associated with virulence (aap; atlE; bhp; hla; hld; ica; IS256; sdrE; sea; tsst) and antimicrobial resistance (aac(6')-Ie-aph(2'')-Ia; aph(3')-IIIa; ant(4')-Ia; blaZ; mecA; vanA/vanB1) were detected by PCR. Results: S. epidermidis grew in 30 (30/50; 60) ICU samples and 20 (20/60; 33) community samples (one isolate per sample per patient/person). All ICU isolates (30/30; 100) were IS256 and hld positive; 22 (22/30; 73) were biofilm/ica positive; 21 (21/30; 70) were hemolytic on blood agar; nine (9/30; 30) contained atlE gene; six (6/30; 20) hla gene; five (5/30; 17) aap gene; and three (3/30; 10) bhp gene. A gene encoding an aminoglycoside-modifying enzyme; aph(3')-IIIa; was highly prevalent (28/30; 93); while blaZ (2/30; 7); mecA (3/30; 10); vanA (3/30; 10) and vanB1 (3/30; 10) were less prevalent. Of the community isolates; one (1/20; 5) was ica positive; two (2/20; 10) formed biofilms; and three (3/20; 15) possessed the atlE gene. bhp; aap; IS256; hld and antimicrobial resistance genes were not detected in community isolates. Conclusions: S. epidermidis from ICU patients in Mulago Hospital is potentially virulent and could be a reservoir for antimicrobial resistant genes
