Does eliminating the preoperative history and physical make a difference in low-risk cataract surgery patients? A before and after study of 30-day morbidity and mortality.

Objective: To evaluate the safety of omitting the conventional preoperative history and physical examination (H&P) for low-risk cataract surgery patients.

Design: Comparison of outcomes before and after the January 1, 2015 system wide implementation of a program that eliminated the conventional preoperative H&P for low-risk patients as identified by a 12-item risk stratification questionnaire.

Participants: Two separate groups of Winnipeg residents who had cataract surgery at the city's sole ophthalmological referral centre between July 1 and December 31, 2014 (preimplementation reference group) or between October 1, 2015 and March 31, 2016 (postimplementation intervention group).

The neural basis of humour comprehension and humour appreciation: The roles of the temporoparietal junction and superior frontal gyrus.

Psychological well-being and social acumen benefit from the recognition of humourous intent and its enjoyment. The enjoyment of humour requires recognition, but humour recognition is not necessarily accompanied by humour enjoyment. Humour recognition is crucial during social interactions, while the associated enjoyment is less critical.

Patients' experience and satisfaction in primary care: secondary analysis using multilevel modelling.

Objective: To explore whether responses to questions in surveys of patients that purport to assess the performance of general practices or doctors reflect differences between practices, doctors, or the patients themselves.

Design: Secondary analysis of data from a study of access to general practice, combining data from a survey of patients with information about practice organisation and doctors consulted, and using multilevel modelling at practice, doctor, and patient level.

Setting: Nine primary care trusts in England.

Warfarin, head injury and bruising.

A 75-year-old woman with a history of recurrent pulmonary emboli and atrial fibrillation presented with shortness of breath. Her warfarin had been stopped 4 weeks previously after a minor fall where a head injury and extensive facial "bruising" was noted. A computed tomography pulmonary angiogram subsequently confirmed another pulmonary embolus.
