Abstract
BACKGROUND Mothers in low-income settings who work in agricultural employment are challenged to meet breastfeeding (BF) recommendations. Recent legislation in Kenya mandates maternity leave and workplace supports, yet the relation of these benefits with BF practices is poorly understood. OBJECTIVES We evaluated the associations with workplace-provided BF supports and BF practices among formally employed mothers in Kenya. The availability of supports was hypothesized to be associated with a higher prevalence and greater odds of exclusive breastfeeding (EBF). METHODS We conducted repeated cross-sectional surveys among formally employed mothers at 1-4 d and 6, 14, and 36 wk (to estimate 24 wk) postpartum in Naivasha, Kenya. We used logistic regression adjusted for maternal age, education, physical burden of work, HIV status, and income to evaluate associations between workplace supports and EBF practices. RESULTS Among formally employed mothers (n = 564), those who used onsite workplace childcare were more likely to practice EBF than those who used community- or home-based childcare at both 6 wk (95.7% compared with 82.4%, P = 0.030) and 14 wk (60.6% compared with 22.2%, P < 0.001; adjusted OR: 5.11; 95% CI: 2.3, 11.7). Likewise, at 14 wk among mothers who currently used daycare centers, a higher proportion of mothers who visited daycare centers at or near workplaces practiced EBF (70.0%) than of those not visiting daycare centers (34.7%, P = 0.005). EBF prevalence was higher among mothers with access to workplace private lactation spaces than among mothers without such spaces (84.6% compared with 55.6%, P = 0.037), and among mothers who lived in workplace housing than those without onsite housing (adjusted OR: 2.06, 95% CI: 1.25, 3.41). CONCLUSIONS Formally employed mothers in Kenya who have access to and use workplace-provided BF supports were more likely to practice EBF than mothers who lacked these supports. As the Kenya Health Act is implemented, lactation rooms, onsite housing and daycare, and transportation to visit children can all support BF and EBF among employed mothers.

Abstract
BACKGROUND In many low- and middle-income countries, improvements in exclusive breastfeeding (EBF) have stalled, delaying reductions in child mortality. Maternal employment is a potential barrier to EBF. OBJECTIVES We evaluated associations between maternal employment and breastfeeding (BF) status. We compared formally and non-formally employed mothers in Naivasha, Kenya, where commercial floriculture and hospitality industries employ many women. METHODS We conducted a cross-sectional survey among mothers (n = 1186) from September 2018 to October 2019 at 4 postpartum time points: at hospital discharge (n = 296) and at 6 wk (n = 298), 14 wk (n = 295), and 36 wk (to estimate BF at 24 wk; n = 297) postpartum. Mothers reported their BF status and reasons for EBF cessation. We used multivariable logistic regression models to test the association between formal maternal employment and 3 outcomes: early BF initiation (within 1 h of birth), EBF at each time point, and continued BF at 9 mo. Models were informed by a directed acyclic graph: a causal diagram used to characterize the relationship among variables that influence the independent (employment) and dependent (BF status) variables. RESULTS EBF did not differ by employment status at hospital discharge or at 6 wk postpartum. However, formally employed mothers were less likely than those not formally employed to report EBF at 14 wk (59.0% compared with 95.4%, respectively; AOR: 0.19; 95% CI: 0.10, 0.34) and at 24 wk (19.0% compared with 49.6%, respectively; AOR: 0.25; 95% CI: 0.14, 0.44). The prevalence of continued BF at 36 wk did not differ by group (98.1% for formally employed compared with 98.5% for non-formally employed women; AOR: 0.80; 95% CI: 0.10, 6.08). The primary reasons reported for early EBF cessation were returning to work (46.5%), introducing other foods based on the child's age (33.5%), or perceived milk insufficiency (13.7%). CONCLUSIONS As more women engage in formal employment in low- and middle-income countries, additional supports to help prolong the period of EBF may be beneficial for formally employed mothers and their children.

Abstract
UNLABELLED SETTINGp: Among human immunodeficiency virus (HIV) infected adults living in tuberculosis (TB) endemic settings, Mycobacterium tuberculosis is a common cause of bloodstream infections. Although young children have an increased propensity for M. tuberculosis dissemination, M. tuberculosis bacteremia is infrequently described in children. OBJECTIVE To determine the prevalence of M. tuberculosis bacteremia in adult and pediatric patients and to examine sources of heterogeneity between estimates. DESIGN Systematic review and meta-analysis. RESULTS Of 1077 reviewed abstracts, 27 publications met the inclusion criteria, yielding 29 independent M. tuberculosis bacteremia prevalence estimates: 22 in adults, 6 in children, and 1 not stratified by age group. The random effects pooled M. tuberculosis bacteremia prevalence in adults was 13.5% (95%CI 10.8-16.2) and 0.4% (95%CI 0-0.9) in children (P for difference = 0.004). Restricting analyses to HIV-infected participants, pooled M. tuberculosis bacteremia prevalence from 21 adult studies was 15.5% (95%CI 12.5-18.5) and 0.8% (95%CI 0-1.8) in three pediatric studies (P = 0.001). Inclusion of pre-determined study-level confounders did not account for observed differences in M. tuberculosis bacteremia prevalence between age groups. CONCLUSION While M. tuberculosis bacteremia appears relatively common in adults, particularly those with HIV infection, bloodstream M. tuberculosis appears to be rare in children.

Abstract
BACKGROUND Shigella is a leading cause of childhood diarrhea mortality in sub-Saharan Africa. Current World Health Organization guidelines recommend antibiotics for children in non cholera-endemic areas only in the presence of dysentery, a proxy for suspected Shigella infection. METHODS To assess the sensitivity and specificity of the syndromic diagnosis of Shigella-associated diarrhea, we enrolled children aged 6 months to 5 years presenting to 1 of 3 Western Kenya hospitals between November 2011 and July 2014 with acute diarrhea. Stool samples were tested using standard methods for bacterial culture and multiplex polymerase chain reaction for pathogenic Escherichia coli. Stepwise multivariable logit models identified factors to increase the sensitivity of syndromic diagnosis. RESULTS Among 1360 enrolled children, median age was 21 months (interquartile range, 11-37), 3.4% were infected with human immunodeficiency virus, and 16.5% were stunted (height-for-age z-score less than -2). Shigella was identified in 63 children (4.6%), with the most common species being Shigella sonnei (53.8%) and Shigella flexneri (40.4%). Dysentery correctly classified 7 of 63 Shigella cases (sensitivity, 11.1%). Seventy-eight of 1297 children without Shigella had dysentery (specificity, 94.0%). The combination of fecal mucous, age over 23 months, and absence of excessive vomiting identified more children with Shigella-infection (sensitivity, 39.7%) but also indicated antibiotics in more children without microbiologically confirmed Shigella (specificity, 82.7%). CONCLUSIONS Reliance on dysentery as a proxy for Shigella results in the majority of Shigella-infected children not being identified for antibiotics. Field-ready rapid diagnostics or updated evidence-based algorithms are urgently needed to identify children with diarrhea most likely to benefit from antibiotic therapy.

Abstract
SETTING Tuberculosis (TB) treatment center at Coast Provincial General Hospital in Mombasa, Kenya. OBJECTIVES To describe TB management practices in a facility in coastal Kenya and identify factors associated with poor treatment outcomes. DESIGN Retrospective review of patient treatment records from January 2008 to June 2009. Treatment outcomes of patients were classified as treatment success (cure or treatment completion) or poor treatment outcome (treatment failure, death or default). Relative risk regression was used to determine the association between exposures of interest and poor treatment outcomes. RESULTS Records were obtained from a total of 183 patients: 142 (78%) had pulmonary TB, 68 (37%) were human immunodeficiency virus (HIV) infected and 81 (44%) had acid-fast bacilli (AFB) positive smear micros- copy. Most treated individuals (86%) achieved a successful treatment outcome as defined by the World Health Organization. Of those with poor treatment outcomes, 64% defaulted, 32% died, and 4% failed treatment. Initial negative AFB smear and HIV co-infection were associated with poor treatment outcomes (RR 3.32, 95%CI 1.22-8.99 and RR 4.61, 95%CI 1.69- 12.59, respectively). CONCLUSION Strategies to accelerate accurate diagnosis of smear-negative TB and increase patient retention during treatment, especially in HIV co-infected individuals, are needed to reduce poor treatment outcomes in Kenya.

Abstract
The production of guidelines for the management of drug-resistant tuberculosis (TB) fits the mandate of the World Health Organization (WHO) to support countries in the reinforcement of patient care. WHO commissioned external reviews to summarise evidence on priority questions regarding case-finding, treatment regimens for multidrug-resistant TB (MDR-TB), monitoring the response to MDR-TB treatment, and models of care. A multidisciplinary expert panel used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to develop recommendations. The recommendations support the wider use of rapid drug susceptibility testing for isoniazid and rifampicin or rifampicin alone using molecular techniques. Monitoring by sputum culture is important for early detection of failure during treatment. Regimens lasting ≥ 20 months and containing pyrazinamide, a fluoroquinolone, a second-line injectable drug, ethionamide (or prothionamide), and either cycloserine or p-aminosalicylic acid are recommended. The guidelines promote the early use of antiretroviral agents for TB patients with HIV on second-line drug regimens. Systems that primarily employ ambulatory models of care are recommended over others based mainly on hospitalisation. Scientific and medical associations should promote the recommendations among practitioners and public health decision makers involved in MDR-TB care. Controlled trials are needed to improve the quality of existing evidence, particularly on the optimal composition and duration of MDR-TB treatment regimens.

Abstract
BACKGROUND The HIV-1 pandemic has disproportionately affected individuals in resource-constrained settings. These areas often also have high prevalence of other infectious diseases, such as helminth infections. It is important to determine if helminth infection affects the progression of HIV-1 in these co-infected individuals. There are biologically plausible reasons for possible effects of helminth infection in HIV-1 infected individuals and findings from some observational studies suggest that helminth infection may adversely affect HIV-1 progression. We sought to evaluate the available evidence from published and unpublished studies to determine if treatment of helminth infection in HIV-1 co-infected individuals impacts HIV-1 progression. OBJECTIVES Our objective was to determine if treating helminth infection in individuals with HIV-1 can reduce the progression of HIV-1 as determined by changes in CD4 count, viral load, or clinical disease progression (including mortality). SEARCH STRATEGY We searched online for published and unpublished studies in The Cochrane Library (Issue 3, 2006), MEDLINE (November 2006), EMBASE (November 2006), CENTRAL (July 2006), AIDSEARCH (August 2006). We also searched databases listing conference abstracts, scanned reference lists of articles, and contacted authors of included studies. SELECTION CRITERIA We searched for randomized and quasi-randomized controlled trials that compared HIV-1 progression as measured by changes in CD4 count, viral load, or clinical disease progression in HIV-1 infected individuals receiving anti-helminth therapy. Observational studies with relevant data were also included. DATA COLLECTION AND ANALYSIS Data regarding changes in CD4 count, HIV-1 RNA levels, clinical staging and/or mortality after treatment of helminth co-infection were extracted from the reports of the studies. MAIN RESULTS Of 6,384 abstracts identified, 15 met criteria for potential inclusion, of which five were eligible for inclusion. In the single randomized controlled trial (RCT) identified, HIV-1 and schistosomiasis co-infected individuals receiving treatment for schistosomiasis had a significantly lower change in plasma HIV-1 RNA over three months (-0.001 log10 copies/mL) compared to those receiving no treatment (+0.21 log10 copies/mL), (p=0.03). Four observational studies met inclusion criteria and all of these suggested a possible beneficial effect of helminth eradication on plasma HIV-1 RNA levels when compared to plasma HIV-1 RNA changes prior to helminth treatment or to helminth-uninfected or persistently helminth-infected individuals. Follow-up duration in these studies ranged from three to six months. The reported magnitude of effect on HIV-1 RNA was variable, ranging from 0.07-1.05 log10 copies/mL. None of the included studies showed a significant benefit of helminth treatment on CD4 decline, clinical staging, or mortality. AUTHORS' CONCLUSIONS There are insufficient data available to determine the potential benefit of helminth eradication in HIV-1 and helminth co-infected adults. Data from a single RCT and multiple observational studies suggest possible benefit in reducing plasma viral load. The impact of de-worming on markers of HIV-1 progression should be addressed in larger randomized studies evaluating species-specific effects and with a sufficient duration of follow-up to document potential differences on clinical outcomes and CD4 decline.

Abstract
Within Nepal, geographic, social, and economic barriers greatly limit access to allopathic health care. The country therefore offered the opportunity to evaluate the effect of antibiotic accessibility (as measured by allopathic medicine consumption) on antibiotic resistance in the normal intestinal flora. The aerobic gram-negative fecal flora of 33-34 healthy adults from each of 3 villages with different access to health care facilities in Kathmandu were examined for antibiotic susceptibility. The frequency of antibiotic resistance decreased significantly with increasing distance from Kathmandu and decreasing population density but did not reflect contact with health care providers or individual medicine consumption. The findings suggest that an individual's overall exposure to antibiotics and antibiotic-resistant bacteria (resulting from close proximity to other community members and to sources of accessible allopathic health care, such as in the vicinity of Kathmandu), has an equal or greater impact on an individual's carriage of antibiotic-resistant bacteria than does direct consumption of antibiotics.
