Abstract Atrial septal defects and ventricular septal defects are often encountered in patients presenting for treatment under anesthesia. The flow mechanisms for both defects are predominantly left to right shunting prior to long-term maladaptive changes that may occur. Close examination of the shunt dynamics demonstrates a minor right to left shunt that occurs as well. The article discusses these dynamics and the impact on an anesthetic plan.

Abstract A core performance target for the English National Health Service (NHS) concerns waiting times at Emergency Departments (EDs), with the aim of minimising long waits. We investigate the drivers of long waits. We analyse weekly data for all major EDs in England from April 2011 to March 2016. A Poisson model with ED fixed effects is used to explore the impact on long (> 4 h) waits of variations in demand (population need and patient case-mix) and supply (emergency physicians, introduction of a Minor Injury Unit (MIU), inpatient bed occupancy, delayed discharges and long-term care). We assess overall ED waits and waits on a trolley (gurney) before admission. We also investigate variation in performance among EDs. The rate of long overall waits is higher in EDs serving older patients (4.2%), where a higher proportion of attendees leave without being treated (15.1%), in EDs with a higher death rate (3.3%) and in those located in hospitals with greater bed occupancy (1.5%). These factors are also significantly associated with higher rates of long trolley waits. The introduction of a co-located MIU is significantly and positively associated with long overall waits, but not with trolley waits. There is substantial variation in waits among EDs that cannot be explained by observed demand and supply characteristics. The drivers of long waits are only partially understood but addressing them is likely to require a multi-faceted approach. EDs with high rates of unexplained long waits would repay further investigation to ascertain how they might improve.

This article discusses the impact of long-term treatment of acromegaly on cardiovascular, metabolic, respiratory and articular complications as well as on malignancies. The main goals of treatment of acromegaly include normalisation of biochemical markers of disease activity, improvement in signs and symptoms of the disease, removal or reduction of tumour mass and preservation of pituitary function, together with prevention of complications. Cardiovascular and respiratory complications are the main causes of morbidity and mortality, whereas neoplasms are a minor cause of increased risk of death. Other associated diseases are arthropathy, carpal tunnel syndrome and reproductive disorders. The prolonged elevation of growth hormone (GH) and insulin-like growth factor (IGF)-I levels results in premature death, whereas strong biochemical control improves wellbeing and restores life expectancy to normal.
