Steps and bumps:precision extraction of discrete states of molecular machines

We report statistical time-series analysis tools providing improvements in the rapid, precision extraction of discrete state dynamics from time traces of experimental observations of molecular machines. By building physical knowledge and statistical innovations into analysis tools, we provide techniques for estimating discrete state transitions buried in highly correlated molecular noise. We demonstrate the effectiveness of our approach on simulated and real examples of steplike rotation of the bacterial flagellar motor and the F1-ATPase enzyme. We show that our method can clearly identify molecular steps, periodicities and cascaded processes that are too weak for existing algorithms to detect, and can do so much faster than existing algorithms. Our techniques represent a step in the direction toward automated analysis of high-sample-rate, molecular-machine dynamics. Modular, open-source software that implements these techniques is provided.

Diabetes management in care homes:steps in the right direction?

Aims: Previous research has identified several inadequacies in management of diabetes within care homes many of which were highlighted in Diabetes UK’s report Diabetes in care homes:awareness, screening, training. The aim of this study was to see if this was still the case and to identify specific areas for improvement. Methods: Thirty care homes in Birmingham were invited to participate in the study. Data were collected using a standard questionnaire based on the Diabetes UK national survey of care homes comprising questions relating to screening, self-management, care planning and local authority support. All returned responses were analysed. Results: Responses were received from 20 of the 30 care homes approached. The mean percentage of residents with diabetes in the care homes sampled was 13.7%. None of the homes screened for diabetes on admission and only 5% screened residents annually.80% of homes acknowledged providing diabetes-specific training to staff. Residents in 95% of homes had a medical review in the last 12 months: 70% with a GP, 20% with a diabetes specialist nurse/nurse. 65% of homes provided support for self-management.45% of care homes did not have individualised care plans for residents with diabetes. 35% of managers reported poor support and guidance from their local authority.Conclusions: Improvements were noted in the care provided to individuals with diabetes living in care homes in Birmingham. Aspects relating to screening, individualised care plans and support to care home staff still need attention.
