RESUMO
This single-centre retrospective study reports the dynamics of the incidence of candida bloodstream infection (CBSI) in 145 patients receiving venovenous extracorporeal membrane oxygenation (ECMO) for respiratory support between January 2014 and December 2018. The incidence rate and odds ratio (OR) of CBSI were calculated, stratified by week of ECMO exposure. Weekly incidence increased throughout the ECMO run, with an increasing trend in OR (P=0.005), and a window of continued risk after decannulation was observed. Of the 13 patients who developed CBSI, five (38%) received empirical micafungin treatment before positive culture due to clinical suspicion. There is a need for prospective studies aiming to improve ECMO diagnostic stewardship practices and discourage unnecessary antifungal prophylaxis or empiric management.

SETTING: Urban slums, Blantyre, Malawi. OBJECTIVE: To explore tuberculosis (TB) community-wide active case finding (cwACF) recall and accompanying messaging 2 years after the intervention. DESIGN: This mixed-methods study used population-weighted random cluster sampling to select three cwACF-receiving and three non-cwACF-receiving neighbourhoods in Blantyre. Qualitative data were collected using 12 focus group discussions (community peer-group members) and five in-depth interviews (TB officers) with script guides based on the concepts of the Health Belief Model (HBM). Thematic analysis was used to explore transcripts employing deductive coding. Questionnaires completed by focus group participants were used to collect quantitative data, providing a 'knowledge score' evaluated through univariate/multivariate analysis, analysis of variance and multiple linear regression. RESULTS: Community peer-group participants (n = 118) retained high awareness and positive opinions of cwACF and recognised the relationship between early diagnosis and reduced transmission, considering cwACF to have prompted subsequent health-seeking behaviour. TB-affected individuals (personal/family: 47.5%) had significantly higher knowledge scores than unaffected individuals (P = 0.039), but only if resident in cwACF-receiving neighbourhoods (P = 0.005 vs. P = 0.582), implying effect modification between exposures, albeit statistically under-powered (P = 0.229). CONCLUSION: Consistent with epidemiological evidence and HBM theory, cwACF may have a permanent impact on knowledge and behaviour, particularly in communities with a high prevalence of TB-affected individuals. Behaviour change strategies should be explicitly included in cwACF planning and evaluation.

The extent of reduction in cholesterol levels, the maintenance of low levels in the long-term, the morbidity and mortality as well as the acceptance of side-effects of the partial ileal bypass (PIB) is reviewed. The mean reduction in cholesterol levels following PIB was 35.2% in males and 35.8% in female patients. The reduction is significant and it is maintained over a 10-year period. The morbidity and mortality is low and side-effects are well tolerated. Our results indicate that the PIB may play an important role in the cholesterol-lowering armamentarium.

The clinical course of 95 comatose trauma patients was prospectively evaluated. The role of clinical findings and diagnostic peritoneal lavage (DPL) combined with computed tomography (CT) were assessed in the diagnosis of abdominal injuries. Seven per cent of the patients were comatose due to hypoperfusion, and did not have a primary brain injury. Of the remaining 88 patients, 28% had an associated abdominal injury. Hypotension predicted an associated abdominal injury with an accuracy of 72%, and a haematocrit less than 30% had an accuracy of 82%. Clinical examination was 50% accurate. DPL was 93% accurate, with a false-positive rate of 10%. No abdominal injuries were present in the group in whom the lavage results were negative, while no unnecessary laparotomies were performed in the group with a 4+ or 5+ positive DPL (calorimetric method). In the group with 1+, 2+ and 3+ positive DPL, 3/15 laparotomies (12%) were done for minor abdominal injuries. Minimising unnecessary laparotomies was achieved by utilising CT to determine the nature and extent of the injury. By using DPL as a screening test, and CT to quantify the injury, unnecessary operations can be avoided, and all injuries can still be diagnosed.
