Trends of and factors associated with cesarean section related surgical site infections in Guinea Delamou, A; Camara, BS; Sidibe, S; Camara, A; Dioubate, N; Ayadi, AME; Tayler-Smith, K; Beavogui, AH; Balde, MD; Zachariah, R Since the adoption of free obstetric care policy in Guinea in 2011, no study has examined the surgical site infections in maternity facilities. The objective of this study was to assess the trends of and factors associated with surgical site infection following cesarean section in Guinean maternity facilities from 2013 to 2015. This was a retrospective cohort study using routine medical data from ten facilities. Overall, the incidence of surgical site infections following cesarean section showed a declining trend across the three periods (10% in 2013, 7% in 2014 and 5% in 2015, P<0.001). Women who underwent cesarean section in 2014 (AOR: 0.70; 95%CI: 0.57-0.84) and 2015 (AOR: 0.43; 95%CI: 0.34-0.55) were less likely to develop surgical site infections during hospital stay than women operated in 2013. In the contrary, women with comorbidities were more likely to experience surgical site infection (AOR: 1.54; 95% CI: 1.25-1.90) than those who did not have comorbidities. The reductions achieved in 2014 and 2015 (during the Ebola outbreak) should be sustained in the post-Ebola context.
Bedaquiline and delamanid in combination for treatment of drug-resistant tuberculosis Mohr, E; Ferlazzo, G; Hewison, C; De Azevedo, V; Isaakidis, P Here we report on the final outcomes for the cohort of 28 patients from Armenia, India, and South Africa who initiated regimens containing the combination of bedaquiline and delamanid from January to August, 2016, for the treatment of multidrug-resistant tuberculosis in our cohort study.1 The median duration on combination treatment was 12 months (interquartile range [IQR] 5·9–20·0); 17 (61%) of 28 patients received the combination for more than 6 months.
Diagnostic value of the urine lipoarabinomannan assay in HIV-positive, ambulatory patients with CD4 below 200 cells/μl in 2 low-resource settings: A prospective observational study. Huerga, H; Mathabire Rucker, SC; Cossa, L; Bastard, M; Amoros, I; Manhica, I; Mbendera, K; Telnov, A; Szumilin, E; Sanchez-Padilla, E; Molfino, L BACKGROUND: Current guidelines recommend the use of the lateral flow urine lipoarabinomannan assay (LAM) in HIV-positive, ambulatory patients with signs and symptoms of tuberculosis (TB) only if they are seriously ill or have CD4 count ≤ 100 cells/μl. We assessed the diagnostic yield of including LAM in TB diagnostic algorithms in HIV-positive, ambulatory patients with CD4 < 200 cells/μl, as well as the risk of mortality in LAM-positive patients who were not diagnosed using other diagnostic tools and not treated for TB. METHODS AND FINDINGS: We conducted a prospective observational study including HIV-positive adult patients with signs and symptoms of TB and CD4 < 200 cells/μl attending 6 health facilities in Malawi and Mozambique. Patients were included consecutively from 18 September 2015 to 27 October 2016 in Malawi and from 3 December 2014 to 22 August 2016 in Mozambique. All patients had a clinical exam and LAM, chest X-ray, sputum microscopy, and Xpert MTB/RIF assay (Xpert) requested. Culture in sputum was done for a subset of patients. The diagnostic yield was defined as the proportion of patients with a positive assay result among those with laboratory-confirmed TB. For the 456 patients included in the study, the median age was 36 years (IQR 31-43) and the median CD4 count was 50 cells/μl (IQR 21-108). Forty-five percent (205/456) of the patients had laboratory-confirmed TB. The diagnostic yields of LAM, microscopy, and Xpert were 82.4% (169/205), 33.7% (69/205), and 40.0% (84/205), respectively. In total, 50.2% (103/205) of the patients with laboratory-confirmed TB were diagnosed only through LAM. Overall, the use of LAM in diagnostic algorithms increased the yield of algorithms with microscopy and with Xpert by 38.0% (78/205) and 34.6% (71/205), respectively, and, specifically among patients with CD4 100-199 cells/μl, by 27.5% (14/51) and 29.4% (15/51), respectively. LAM-positive patients not diagnosed through other tools and not treated for TB had a significantly higher risk of mortality than LAM-positive patients who received treatment (adjusted risk ratio 2.57, 95% CI 1.27-5.19, p = 0.009). Although the TB diagnostic conditions in the study sites were similar to those in other resource-limited settings, the added value of LAM may depend on the availability of microscopy or Xpert results. CONCLUSIONS: LAM has diagnostic value for identifying TB in HIV-positive patients with signs and symptoms of TB and advanced immunodeficiency, including those with a CD4 count of 100-199 cells/μl. In this study, the use of LAM enabled the diagnosis of TB in half of the patients with confirmed TB disease; without LAM, these patients would have been missed. The rapid identification and treatment of TB enabled by LAM may decrease overall mortality risk for these patients.
High incidence of intended partner pregnancy among men living with HIV in rural Uganda: Implications for safer conception services. Kaida, A; Kabakyenga, J; Bwana, M; Bajunirwe, F; Mayindike, W; Bennett, K; Kembabazi, A; Haberer, JE; Boum, Y; Martin, JN; Hunt, PW; Bangsberg, DR; Matthews, LT Many men with HIV express fertility intentions and nearly half have HIV-uninfected sexual partners. We measured partner pregnancy among a cohort of men accessing antiretroviral therapy (ART) in Uganda. Self-reported partner pregnancy incidence and bloodwork (CD4, HIV-RNA) were collected quarterly. Interviewer-administered questionnaires assessed men's sexual and reproductive health annually and repeated at time of reported pregnancy (2011-2015). We measured partner pregnancy incidence overall, by pregnancy intention, and by reported partner HIV-serostatus. We assessed viral suppression (≤400 copies/mL) during the peri-conception period. Cox proportional hazard regression with repeated events identified predictors of partner pregnancy. Among 189 men, baseline median age was 39.9 years [IQR:34.7,47.0], years on ART was 3.9 [IQR:0.0,5.1], and 51% were virally suppressed. Over 530.2 person-years of follow-up, 63 men reported 85 partner pregnancies (incidence=16.0/100 person-years); 45% with HIV-serodifferent partners. By three years of follow-up, 30% of men reported a partner pregnancy, with no difference by partner HIV-serostatus (p=0.75). 69% of pregnancies were intended, 18% wanted but mis-timed, and 8% unwanted. 78% of men were virally suppressed prior to pregnancy report. Men who were younger (aHR:0.94/year;95%CI:0.89-0.99), had incomplete primary education (aHR:2.95;95%CI:1.36-6.40), and reported fertility desires (aHR:2.25;95%CI:1.04-4.85) had higher probability of partner pregnancy. A high incidence of intended partner pregnancy highlights the need to address men's reproductive goals within HIV care. Nearly half of pregnancy partners were at-risk for HIV and one-quarter of men were not virally suppressed during peri-conception. Safer conception care provides opportunity to support men's health and reproductive goals, while preventing HIV transmission to women and infants.
A screening tool for psychological difficulties in children aged 6 to 36 months: cross-cultural validation in Kenya, Cambodia and Uganda. Nackers, F; Roederer, T; Marquer, C; Ashaba, S; Maling, S; Mwanga-Amumpaire, J; Muny, S; Sokeo, C; Shom, V; Palha, M; Lefebvre, P; Kirubi, BW; Kamidigo, G; Falissard, B; Moro, MR; Grais, RF In low-resource settings, the lack of mental health professionals and cross-culturally validated screening instruments complicates mental health care delivery. This is especially the case for very young children. Here, we aimed to develop and cross-culturally validate a simple and rapid tool, the PSYCa 6-36, that can be administered by non-professionals to screen for psychological difficulties among children aged six to 36 months. A primary validation of the PSYCa 6-36 was conducted in Kenya (n = 319 children aged 6 to 36 months; 2014), followed by additional validations in Kenya (n = 215; 2014) Cambodia (n = 189; 2015) and Uganda (n = 182; 2016). After informed consent, trained interviewers administered the PSYCa 6-36 to caregivers participating in the study. We assessed the psychometric properties of the PSYCa 6-36 and external validity was assessed by comparing the results of the PSYCa 6-36 against a clinical global impression severity [CGIS] score rated by an independent psychologist after a structured clinical interview with each participant. The PSYCa 6-36 showed satisfactory psychometric properties (Cronbach's alpha > 0.60 in Uganda and > 0.70 in Kenya and Cambodia), temporal stability (intra-class correlation coefficient [ICC] > 0.8), and inter-rater reliability (ICC from 0.6 in Uganda to 0.8 in Kenya). Psychologists identified psychological difficulties (CGIS score > 1) in 11 children (5.1%) in Kenya, 13 children (8.7%) in Cambodia and 15 (10.5%) in Uganda, with an area under the receiver operating characteristic curve of 0.65 in Uganda and 0.80 in Kenya and Cambodia. The PSYCa 6-36 allowed for rapid screening of psychological difficulties among children aged 6 to 36 months among the populations studied. Use of the tool also increased awareness of children's psychological difficulties and the importance of early recognition to prevent long-term consequences. The PSYCa 6-36 would benefit from further use and validation studies in popula`tions with higher prevalence of psychological difficulties.
Patient and health-care worker experiences of an HIV viral load intervention using SMS: A qualitative study. Venables, E; Ndlovu, Z; Munyaradzi, D; Martinez-Perez, G; Mbofana, E; Nyika, P; Chidawanyika, H; Bygrave, H; Garone, D Mobile Health or mHealth interventions, including Short Message Service (SMS), can help increase access to care, enhance the efficiency of health service delivery and improve diagnosis and treatment for HIV. Text messaging, or SMS, allows for the low cost transmission of information, and has been used to send appointment reminders, information about HIV counselling and treatment, messages to encourage adherence and information on nutrition and side-effects. HIV Viral Load (VL) monitoring is recommended by the WHO and has been progressively adopted in many settings. In Zimbabwe, implementation of VL is routine and has been rolled out with support of Médecins Sans Frontières (MSF) since 2012. An SMS intervention to assist with the management of VL results was introduced in two rural districts of Zimbabwe. After completion of the HIV VL testing at the National Microbiology Reference Laboratory in Harare, results were sent to health facilities via SMS. Consenting patients were also sent an SMS informing them that their viral load results were ready for collection at their nearest health facilities. No actual VL results were sent to patients. A qualitative study was conducted in seven health-care facilities using in-depth interviews (n = 32) and focus group discussions (n = 5) to explore patient and health-care worker experiences of the SMS intervention. Purposive sampling was used to select participants to ensure that male and female patients, as well as those with differing VL results and who lived differing distances from the clinics were included. Data were transcribed, translated from Shona into English, coded and thematically analysed using NVivo software. The VL SMS intervention was considered acceptable to patients and health-care workers despite some challenges in implementation. The intervention was perceived by health-care workers as improving adherence and well-being of patients as well as improving the management of VL results at health facilities. However, there were some concerns from participants about the intervention, including challenges in understanding the purpose and language of the messages and patients coming to their health facility unnecessarily. Health-care workers were more concerned than patients about unintentional HIV disclosure relating to the content of the messages or phone-sharing. This was an innovative intervention in Zimbabwe, in which SMS was used to send VL results to health-care facilities, and notifications of the availability of VL results to patients. Interventions such as this have the potential to reduce unnecessary clinic visits and ensure patients with high VL results receive timely support, but they need to be properly explained, alongside routine counselling, for patients to fully benefit. The findings of this study also have potential policy implications, as if implemented well, such an SMS intervention has the potential to help patients adopt a more active role in the self-management of their HIV disease, become more aware of the importance of adherence and VL monitoring and seek follow-up at clinics when results are high.
2017 Outbreak of Ebola Virus Disease in Northern Democratic Republic of Congo Nsio, J; Kapetshi, J; Makiala, S; Raymond, F; Tshapenda, G; Boucher, N; Corbeil, J; Okitandjate, A; Mbuyi, G; Kiyele, M; Mondonge, V; Kikoo, MJ; Van Herp, M; Barboza, P; Petrucci, R; Benedetti, G; Formenty, P; Muzinga, BM; Kalenga, OI; Ahuka, S; Fausther-Bovendo, H; Ilunga, BK; Kobinger, GP; Muyembe, JJT Background In 2017, the Democratic Republic of the Congo (DRC) recorded its eighth Ebola virus disease (EVD) outbreak, approximately 3 years after the previous outbreak. Methods Suspect cases of EVD were identified on the basis of clinical and epidemiological information. Reverse transcription–polymerase chain reaction (RT-PCR) analysis or serological testing was used to confirm Ebola virus infection in suspected cases. The causative virus was later sequenced from a RT-PCR–positive individual and assessed using phylogenetic analysis. Results Three probable and 5 laboratory-confirmed cases of EVD were recorded between 27 March and 1 July 2017 in the DRC. Fifty percent of cases died from the infection. EVD cases were detected in 4 separate areas, resulting in > 270 contacts monitored. The complete genome of the causative agent, a variant from the Zaireebolavirus species, denoted Ebola virus Muyembe, was obtained using next-generation sequencing. This variant is genetically closest, with 98.73% homology, to the Ebola virus Mayinga variant isolated from the first DRC outbreaks in 1976–1977. Conclusion A single spillover event into the human population is responsible for this DRC outbreak. Human-to-human transmission resulted in limited dissemination of the causative agent, a novel Ebola virus variant closely related to the initial Mayinga variant isolated in 1976–1977 in the DRC.
Screening of asymptomatic rheumatic heart disease among refugee/migrant children and youths in Italy. Condemi, F; Rossi, G; Miguel, L; Pagano, A; Zamatto, F; Marini, S; Romeo, F; De Maio, G Rheumatic heart disease (RHD) is a chronic condition responsible of congestive heart failure, stroke and arrhythmia. Almost eradicated in high-income countries (HIC), it persists in low- and middle-income countries. The purpose of the study was to assess the feasibility and meaningfulness of ultrasound-based RHD screening among the population of unaccompanied foreign minors in Italy and determine the burden of asymptomatic RHD among this discrete population. From February 2016 to January 2018, Médecins Sans Frontières conducted a weekly mobile screening by echocardiography in reception centers and family houses for unaccompanied foreign minors in Rome, followed by fix echocardiographic retesting for those resulting positive at screening. 'Definite' and 'borderline' cases were defined according to the World Hearth Federation criteria. Six hundred fifty-three individuals (13-26 years old) were screened; 95.6% were below 18 years old (624/653). Six 'definite RHD' were identified at screening, yielding a detection rate of 9.2‰ (95% CI 4.1-20.3‰), while 285 (436.4‰) were defined as 'borderline' (95% CI 398.8-474.9‰). Out of 172 "non-negative borderline" cases available for being retested (113 "non-negative borderline" lost in follow-up), additional 11 were categorized as 'definite RHD', for a total of 17 'definite RHD', yielding a final prevalence of 26.0‰ (95% CI 16.2-41.5‰) (17/653), and 122 (122/653) were confirmed as 'borderline' (final prevalence of 186.8‰, 95% CI 158.7-218.7). In multivariate logistic regression analysis the presence of systolic murmur was a strong predictor for both 'borderline' (OR 4.3 [2.8-6.5]) and 'definite RHD' (OR 5.2 [1.7-15.2]), while no specific country/geographic area of origin was statistically associated with an increased risk of latent, asymptomatic RHD. Screening for RHD among the unaccompanied migrant minors in Italy proved to be feasible. The burden of 'definite RHD' was similar to that identified in resource-poor settings, while the prevalence of 'borderline' cases was higher than reported in other studies. In view of these findings, the health system of high-income countries, hosting migrants and asylum seekers, are urged to adopt screening for RHD in particular among the silent and marginalized population of refugee and migrant children.
Further evidence of Mycobacterium tuberculosis in the sputum of culture-negative pulmonary tuberculosis suspects using an ultrasensitive molecular assay. Guillermo, M; Solange, V; Orr, B; White, L; Gaeddert, M; Miller, NS; Mpeirwe, M; Orikiriza, P; Mwanga-Amumpaire, J; Boum, Y; Palaci, M; Dietze, R; Jones-Lopez, EC BACKGROUND: Rapid diagnosis of pulmonary tuberculosis (TB) is critical to TB control. However, many patients with paucibacillary TB disease remain undiagnosed. Current TB elimination goals require new tools to diagnose early disease. We evaluated performance of the Totally Optimized PCR (TOP) TB assay, a novel ultrasensitive molecular test. METHODS: We assessed analytical specificity against nontuberculous mycobacteria (NTM), and estimated the diagnostic accuracy of TOP in a pilot study in Brazil (n = 46) and a cross-sectional study in Boston (n = 60). We compared TOP results to culture and a composite reference standard (CRS). RESULTS: TOP exhibited no cross-reactivity against NTM. We tested 132 respiratory specimens from 106 patients with suspected pulmonary TB. The pilot demonstrated feasibility and 100% (95% CI 85-100) sensitivity in predominantly smear-positive specimens; TOP's specificity against solid media culture was low (58%, 37-77) but improved against a CRS (93%, 68-100). Similarly, when using the CRS in the Boston study, TOP (88%, 1-99) had greater sensitivity than solid or liquid media culture (25%, 3-65) and similar specificity (both 100%, 93-100). CONCLUSIONS: The TOP assay enables detection of M. tuberculosis in culture-negative paucibacillary disease. While the use of TOP for the diagnosis of paucibacillary disease will require further clinical validation, its high sensitivity indicate a more immediate utility as a rule out TB test. We regret that this article is behind a paywall.
The Continuing Value of CD4 Cell Count Monitoring for Differential HIV Care and Surveillance Rice, B; Boulle, A; Schwarcz, S; Shroufi, A; Rutherford, G; Hargreaves, J The move toward universal provision of antiretroviral therapy and the expansion of HIV viral load monitoring call into question the ongoing value of CD4 cell count testing and monitoring. We highlight the role CD4 monitoring continues to have in guiding clinical decisions and measuring and evaluating the epidemiology of HIV. To end the HIV/AIDS epidemic, we require strategic information, which includes CD4 cell counts, to make informed clinical decisions and effectively monitor key surveillance indicators.
Treatment outcomes of patients switching from an injectable drug to bedaquiline during short standardized MDR-TB treatment in Mozambique Bastard, M; Molfino, L; Mutaquiha, C; Galindo, MA; Zindoga, P; Vaz, D; Mahinca, I; du Cros, P; Rusch, B; Telnov, A Bedaquiline was recommended by WHO as the preferred option in treatment of MDR-TB patients with long regimen. However, no recommendation was given for the short MDR-TB regimen. Data from our small cohort of patients who switched injectable dug to bedaquiline suggest that bedaquiline based short regimen is effective and safe.
Delays in arrival and treatment in emergency departments: Women, children and non-trauma consultations the most at risk in humanitarian settings Guzman, IB; Cuesta, JG; Trelles, M; Jaweed, O; Cherestal, S; van Loenhout, JAF; Guha-Sapir, D Introduction Delays in arrival and treatment at health facilities lead to negative health outcomes. Individual and external factors could be associated with these delays. This study aimed to assess common factors associated with arrival and treatment delays in the emergency departments (ED) of three hospitals in humanitarian settings. Methodology This was a cross-sectional study based on routine data collected from three MSF-supported hospitals in Afghanistan, Haiti and Sierra Leone. We calculated the proportion of consultations with delay in arrival (>24 hours) and in treatment (based on target time according to triage categories). We used a multinomial logistic regression model (MLR) to analyse the association between age, sex, hospital and diagnosis (trauma and non-trauma) with these delays. Results We included 95,025 consultations. Males represented 65.2%, Delay in arrival was present in 27.8% of cases and delay in treatment in 27.2%. The MLR showed higher risk of delay in arrival for females (OR 1.2, 95% CI 1.2–1.3), children <5 (OR 1.4, 95% CI 1.4–1.5), patients attending to Gondama (OR 30.0, 95% CI 25.6–35.3) and non-trauma cases (OR 4.7, 95% CI 4.4–4.8). A higher risk of delay in treatment was observed for females (OR 1.1, 95% CI 1.0–1.1), children <5 (OR 2.0, 95% CI 1.9–2.1), patients attending to Martissant (OR 14.6, 95% CI 13.9–15.4) and non-trauma cases (OR 1.6, 95% CI 1.5–1.7). Conclusions Women, children <5 and non-trauma cases suffered most from delays. These delays could relate to educational and cultural barriers, and severity perception of the disease. Treatment delay could be due to insufficient resources with consequent overcrowding, and severity perception from medical staff for non-trauma patients. Extended community outreach, health promotion and support to community health workers could improve emergency care in humanitarian settings.
