Outliers from national audits: their analysis and use by the Care Quality Commission in quality assurance and regulation of healthcare services in England.

The Care Quality Commission (CQC) is the independent regulator of health and adult social care in England. As part of the intelligence-driven approach to regulation, the CQC works closely with national clinical audit bodies to identify key metrics which reflect quality of care and track the performance of providers against these metrics. Where outliers on national audits are identified that may reflect risks to patients, the CQC encourages the hospital to identify any learning points and implement changes to improve patient care.

Development of a Qualitative Quantitative Polymerase Chain Reaction Test to Identify Patients Failing First-Line Therapy to Non-Nucleotide Reverse Transcriptase Inhibitor.

Antiretroviral therapy (ART) can be compromised by selection of drug resistance strains, which can be promoted by lack of adherence during therapy and drug tolerance, and some of these drug-resistant strains can persist for years as minority populations. The K103N drug resistance mutation is selected by the use of non-nucleotide reverse transcriptase inhibitors, including nevirapine or efavirenz (EFV), used in low-income countries. Here we describe the use of a less expensive qualitative point mutation polymerase chain reaction (PMqPCR) targeting K103N mutation.

Trypanosoma cruzi: parasitaemia produced in mice does not seem to be related to in vitro parasite-cell interaction.

The interaction of Trypanosoma cruzi strains producing subpatent or high parasitaemia in mice with mouse macrophages, Vero and L929 cells was evaluated using tissue culture trypomastigotes. Macrophages were the cells most readily infected while Vero cells presented the highest parasite intracellular multiplication rates. Subpatent strains were equal or more infective than the high parasitaemia.
