Voluntary medical male circumcision: Safety and satisfacion at Migori County Hospital

Background: The World Health Organization (WHO) recommended Voluntary Medical Male Circumcision (VMMC) as an HIV prevention option for men based on evidence showing a reduction in HIV acquisition of 50% to 60%. Based in this evidence, the rapid expansion of VMMC in sub Saharan Africa has raised concerns on the capacity of VMMC programs to provide sustainable high quality and safe VMMC services.Objective: To determine the rates and correlates of adverse events following VMMC among clients attending Migori County Hospital.Design: Descriptive cross sectional study Setting: Migori County Referral Hospital, Kenya.Subjects: Between November and December 2015, 138 men receiving VMMC services at Migori County hospital were interviewed during their follow up visits within 7 days following the procedure. We systematically sampled every third participant attending their follow up visit. Face to face interviews were conducted to obtain data on demographics and levels of satisfaction, and physical examination to determine any adverse events after circumcision. Fishers exact was used to test for correlates of adverse events among participants.Results: The mean age of participants was 22 years, Standard Deviation (SD) ±5) .About two-thirds (63.8%) had reached secondary level education, 26(18.8%) tertiary level, 23(16.7%) primary level and only 1(0.7%) had no education. The majority 100(72.5%) reported being aware of possible adverse events following male circumcision and almost all 135 (97.8%) participants reported having adhered to wound care instructions. The rate of mild and moderate adverse events was 58.7% and 2.9%, respectively. There was no severe adverse event reported. Bathing and not changing underpants was associated with adverse events. The Majority 137 (99.3%) of participants were highly satisfied with the circumcision procedure and the post-operative care services they received.Conclusion: These results imply that VMMC in this setting can be delivered safely and effectively with high client satisfaction

Symptom screen: diagnostic usefulness in detecting pulmonary tuberculosis in HIV-infected pregnant women in Kenya

OBJECTIVE: To determine the diagnostic usefulness of tuberculosis (TB) symptom screening to detect active pulmonary TB among human immunodeficiency virus (HIV) infected pregnant women in two PMTCT (prevention of mother-to-child transmission) clinics in western Kenya that are supported by the United States Agency for International Development–Academic Model Providing Access to Healthcare partnership. DESIGN: Cross-sectional study. Participants were interviewed for TB symptoms with a standardized questionnaire (cough >2 weeks, fever, night sweats, weight loss or failure to gain weight). Those with cough submitted sputum specimens for smear microscopy for acid-fast bacilli and mycobacterial culture. Women at >14 weeks gestation underwent shielded chest radiography (CXR). RESULTS: Of 187 HIV-infected women, 38 (20%) were symptom screen-positive. Of these, 21 had a cough for >2 weeks, but all had negative sputum smears and mycobacterial cultures. CXRs were performed in 26 symptomatic women: three were suggestive of TB (1 miliary, 1 infiltrates and 1 cavitary). Of 149 women with a negative symptom screen, 100 had a CXR and seven had a CXR suggestive of TB (1 cavitary, 2 miliary and 4 infiltrates). CONCLUSION: This study did not support the utility of isolated symptom screening in identification of TB disease in our PMTCT setting. CXR was useful in identification of TB suspects in both symptomatic and asymptomatic women

Uptake of isoniazid preventive therapy and its associated factors among HIV positive patients in an urban health centre, Kenya

Background: Isoniazid Preventive Therapy (IPT) is an effective intervention for prevention of tuberculosis (TB) among HIV positive patients, and its use is recommended by the World Health Organization (WHO). Unfortunately the uptake of IPT in Kenya remains low (33%-40%) with limited knowledge on the factors that affect its uptake.Objective: To determine the uptake of IPT and its associated factors among HIV-positive patients enrolled in a urban health centre.Design: Hospital based cross-sectional studySetting: Riruta Health Centre, Nairobi, KenyaSubjects: HIV-positive patients ≥18 years who have been on care and treatment services in the health centre for at least six months preceding the study.Results: Four hundred and thirty six participants were enrolled with a mean age of 41 years (standard deviation± 9years). Females were 276 (63%), anti-retroviral therapy uptake of 427 (98%) and overall IPT uptake rate of 336 (77%). On multivariate analysis, fear of acquiring TB (adjusted odds ratio (AOR) 4.6, 95% confidence interval, CI 2.6-8.1), having received IPT-associated health education (AOR 5.0, 95% CI 3.0-8.4) and having a good relationship with the healthcare worker (HCW) (AOR 2.0, 95% CI 1.2-3.4) were independently associated with initiation of IPT.Conclusion: The uptake rate was above the current national coverage but fell below the national set target of 90%. Fear of acquiring TB, receipt of IPT-associated health education and favourable relationship with the HCWs promoted the initiation of IP

Environment shapes the accessible daptomycin resistance mechanisms in enterococcus faecium

Daptomycin binds to bacterial cell membranes and disrupts essential cell envelope processes, leading to cell death. Bacteria respond to daptomycin by altering their cell envelopes to either decrease antibiotic binding to the membrane or by diverting binding away from septal targets. In Enterococcus faecalis, daptomycin resistance is typically coordinated by the three-component cell envelope stress response system, LiaFSR. Here, studying a clinical strain of multidrug-resistant Enterococcus faecium containing alleles associated with activation of the LiaFSR signaling pathway, we found that specific environments selected for different evolutionary trajectories, leading to high-level daptomycin resistance. Planktonic environments favored pathways that increased cell surface charge via yvcRS upregulation of dltABCD and mprF, causing a reduction in daptomycin binding. Alternatively, environments favoring complex structured communities, including biofilms, evolved both diversion and repulsion strategies via divIVA and oatA mutations, respectively. Both environments subsequently converged on cardiolipin synthase (cls) mutations, suggesting the importance of membrane modification across strategies. Our findings indicate that E. faecium can evolve diverse evolutionary trajectories to daptomycin resistance that are shaped by the environment to produce a combination of resistance strategies. The accessibility of multiple and different biochemical pathways simultaneously suggests that the outcome of daptomycin exposure results in a polymorphic population of resistant phenotypes, making E. faecium a recalcitrant nosocomial pathogen

J Infect Dis

BACKGROUND: In 2015, the laboratory at the Ebola treatment center in Coyah, Guinea, confirmed Ebola virus disease (EVD) in 286 patients. Cycle threshold (Ct) in the Ebola virus RT-PCR and 13 blood chemistry parameters were measured on admission and during hospitalization. Favipiravir treatment was offered to EVD patients on compassionate use basis. METHODS: To reduce biases in the raw field data, we carefully selected 163 of the 286 EVD patients for a retrospective study to assess associations between potential risk factors, alterations in blood chemistry, favipiravir treatment, and outcome. RESULTS: The case fatality rate in favipiravir-treated patients was lower than in untreated patients (31/73 [42.5%] vs. 52/90 [57.8%], p = 0.053 in univariate analysis). In the multivariate regression analysis, higher Ct value and younger age were associated with survival (p <0.001), while favipiravir treatment showed no statistically significant effect (p = 0.11). However, Kaplan-Meier analysis indicated a longer survival time in the favipiravir-treated group (p = 0.015). The study also showed characteristic changes in blood chemistry in fatal cases vs. survivors. CONCLUSIONS: Consistent with the JIKI trial, this retrospective study reveals a trend toward improved survival in favipiravir-treated patients; however, the effect was not statistically significant except for survival time
