Has the utilisation of Xpert® MTB/RIF in Manicaland Province, Zimbabwe, improved with new guidance on whom to test?
Setting: Manicaland Province, Zimbabwe. Objectives: To compare the utilisation and results of deploying Xpert® MTB/RIF in 13 (one provincial, six district and six rural) hospitals between January and June 2016, when Xpert was recommended only for those with presumptive multidrug-resistant tuberculosis (MDR-TB) and coinfection with human immunodeficiency virus (HIV), and between January and June 2017, when Xpert was recommended for all presumptive TB patients. Design: This was a cross-sectional study. Results: Xpert assays averaged 759 monthly in 2016 and 1430 monthly in 2017 (88% increase). Utilisation of Xpert averaged 22% monthly in 2016 and 42% in 2017 (88% increase). In 2017, utilisation of Xpert was significantly higher in provincial (82%) than in district (51%) and rural (26%) hospitals (P < 0.001). The proportion of successful assays that detected TB decreased significantly from 13% in 2016 to 7% in 2017 (a 46% decrease, P < 0.001); this phenomenon was observed in all types of hospital. The proportion of persons detected with rifampicin-resistant TB was similar between hospitals (4% in 2016 and 3% in 2017). The proportion of registered TB cases with bacteriological confirmation increased from 48% in 2016 to 53% in 2017 (P = 0.04). Conclusion: Xpert use in all presumptive TB patients led to a significant increase in assay numbers and utilisation of Xpert instruments, resulting in more bacteriological confirmation of cases

Assessing the impact of drinking water and sanitation on diarrhoeal disease in low- and middle-income settings: systematic review and meta-regression.
ObjectiveTo assess the impact of inadequate water and sanitation on diarrhoeal disease in low- and middle-income settings.MethodsThe search strategy used Cochrane Library, MEDLINE & PubMed, Global Health, Embase and BIOSIS supplemented by screening of reference lists from previously published systematic reviews, to identify studies reporting on interventions examining the effect of drinking water and sanitation improvements in low- and middle-income settings published between 1970 and May 2013. Studies including randomised controlled trials, quasi-randomised trials with control group, observational studies using matching techniques and observational studies with a control group where the intervention was well defined were eligible. Risk of bias was assessed using a modified Ottawa-Newcastle scale. Study results were combined using meta-analysis and meta-regression to derive overall and intervention-specific risk estimates.ResultsOf 6819 records identified for drinking water, 61 studies met the inclusion criteria, and of 12,515 records identified for sanitation, 11 studies were included. Overall, improvements in drinking water and sanitation were associated with decreased risks of diarrhoea. Specific improvements, such as the use of water filters, provision of high-quality piped water and sewer connections, were associated with greater reductions in diarrhoea compared with other interventions.ConclusionsThe results show that inadequate water and sanitation are associated with considerable risks of diarrhoeal disease and that there are notable differences in illness reduction according to the type of improved water and sanitation implemented
The Use of the Autism Diagnostic Interview-Revised with a Latino Population of Adolescents and Adults with Autism
Research shows that Latinos are less likely to be diagnosed with autism than their non-Latino counterparts. One factor that may contribute to these differences is that autism diagnostic instruments have not been adapted for the Latino population. The present study compared scores from the Autism Diagnostic Interview-Revised for two groups: 48 Latino adolescents and adults with autism and a matched sample of 96 non-Latino Whites. There were no significant differences between the two groups in total impairments in social reciprocity or communication. However, lower levels of restrictive-and-repetitive behaviors were found among Latino adolescents and adults with autism compared to Whites. Findings suggest that there may be cultural equivalency in some domains, but others may warrant further exploration
