Invloed van de pH op het aantonen van bacteriegroeiremmende stoffen in rauwe melk
Een hoeveelheid melk wordt toegevoegd aan een vaste voedingsbodem, waaraan sporen van Bacillus stearothermophilus var. calidolactis ATCC 10149, broomcresolpurper en trimethoprim zijn toegevoegd. Normale groei van en zuurproduktie door het micro-organisme veroorzaakt een kleurverandering van de pH indicator van paars naar geel. De aanwezigheid in de melk van stoffen die remmend werken op de groei van het micro-organisme, hebben tot gevolg dat de kleur van de pH indicator paars blijft. Nagegaan is of verhoging van de pH van de vaste voedingsbodem deze screeningsmethode gevoeliger maakt voor het opsporen van bacterie groeiremmende stoffen welke een hogere activiteit vertonen in een basisch milieu

Randomised trials relevant to mental health conducted in low and middle-income countries: a survey
<p>Abstract</p> <p>Background</p> <p>A substantial proportion of the psychiatric burden of disease falls on the world's poorest nations, yet relatively little is known about randomised trials conducted in these countries. Our aim was to identify and describe a representative sample of mental health trials from low and middle-income countries.</p> <p>Methods</p> <p>6107 electronic records, most with full text copies, were available following extensive searches for randomised or potentially randomised trials from low and middle-income countries published in 1991, 1995 and 2000. These records were searched to identify studies relevant to mental health. Data on study characteristics were extracted from the full text copies.</p> <p>Results</p> <p>Trials relevant to mental health were reported in only 3% of the records. 176 records reporting 177 trials were identified: 25 were published in 1991, 45 in 1995, and 106 in 2000. Participants from China were represented in 46% of trials described. 68% of trials had <100 participants. The method of sequence generation was described in less than 20% of reports and adequate concealment of allocation was described in only 12% of reports. Participants were most frequently adults with unipolar depression (36/177) or schizophrenia (36/177). 80% of studies evaluated pharmacological interventions, a third of which were not listed by WHO as essential drugs. 41% of reports were indexed on PubMed; this proportion decreased from 68% in 1991 to 32% in 2000.</p> <p>Conclusion</p> <p>In terms of overall health burden, trial research activity from low and middle-income countries in mental health appears to be low, and in no area adequately reflects need.</p
Variation in the provision and practice of implant-based breast reconstruction in the UK: Results from the iBRA national practice questionnaire
Introduction The introduction of biological and synthetic meshes has revolutionised the practice of implant-based breast reconstruction (IBBR) but evidence for effectiveness is lacking. The iBRA (implant Breast Reconstruction evAluation) study is a national trainee-led project that aims to explore the practice and outcomes of IBBR to inform the design of a future trial. We report the results of the iBRA National Practice Questionnaire (NPQ) which aimed to comprehensively describe the provision and practice of IBBR across the UK. Methods A questionnaire investigating local practice and service provision of IBBR developed by the iBRA Steering Group was completed by trainee and consultant leads at breast and plastic surgical units across the UK. Summary data for each survey item were calculated and variation between centres and overall provision of care examined. Results 81 units within 79 NHS-hospitals completed the questionnaire. Units offered a range of reconstructive techniques, with IBBR accounting for 70% (IQR:50–80%) of participating units' immediate procedures. Units on average were staffed by 2.5 breast surgeons (IQR:2.0–3.0) and 2.0 plastic surgeons (IQR:1.0–3.0) performing 35 IBBR cases per year (IQR:20-50). Variation was demonstrated in the provision of novel different techniques for IBBR especially the use of biological (n = 62) and synthetic (n = 25) meshes and in patient selection for these procedures. Conclusions The iBRA-NPQ has demonstrated marked variation in the provision and practice of IBBR in the UK. The prospective audit phase of the iBRA study will determine the safety and effectiveness of different approaches to IBBR and allow evidence-based best practice to be explored
