Abstract
Modern anaesthetists rely on the intravenous route for administration of drugs and fluids. This paper traces the development of intravenous equipment from the first, tentative experiments with the intravenous route through to the first intravenous cannulas.

Abstract
Malignant hyperthermia was an unknown condition in 1960 although there had always been occasional patients who died mysteriously under anaesthesia. The nature of the disease became apparent when a young Melbourne man presented that year with a compound fracture and a family history of deaths under anaesthesia. He survived his anaesthetic due to the combined efforts of the anaesthetist and the surgeon. His family history was then investigated by the physicians. Over the next 20 years the cause of the disease was discovered and eventually a treatment was found. This article is based around a series of interviews with many of the participants in this story.

Abstract
We prospectively measured hand and wrist function in rheumatoid patients undergoing excision of the distal ulna. Range of motion, visual analogue pain scores and grip strength were measured in 22 wrists, and the Jebsen hand function test was administered to seven patients, preoperatively and at 3 and 12 months. At 1 year there were improvements in forearm pronation ( P = 0.04), supination ( P = 0.03) and wrist extension ( P = 0.02), but a reduction in flexion ( P = 0.009). Active radial deviation was reduced and ulnar deviation increased. There was a significant improvement in grip strength ( P = 0.05) and reduction in wrist pain ( P = < 0.0001). At 1 year the Jebsen hand function test showed improvements in simulated feeding, stacking checkers, and lifting large empty cans. Excision of the distal ulna in rheumatoid patients results in an improvement in some aspects of hand function.

Abstract
We describe the design and function of a new time and space resolved x-ray spectrometer for use in Z-pinch inertial confinement fusion and radiation source development experiments. The spectrometer is designed to measure x-rays in the range of 0.5-1.5 Å (8-25 keV) with a spectral resolution λ/Δλ ∼ 400. The purpose of this spectrometer is to measure the time- and one-dimensional space-dependent electron temperature and density during stagnation. These relatively high photon energies are required to escape the dense plasma created at stagnation and to obtain sensitivity to electron temperatures ≳3 keV. The spectrometer is of the Cauchois type, employing a large 30 × 36 mm2, transmissive quartz optic for which a novel solid beryllium holder was designed. The performance of the crystal was verified using offline tests, and the integrated system was tested using experiments on the Z pulsed power accelerator.

Abstract
AIM To evaluate major/minor discrepancy rates for provisional (initial) and addendum (supplementary senior review) emergency computed tomography (CT) reports in patients presenting with non-traumatic abdominal pain. MATERIALS AND METHODS Ethical approval for this type of study is not required in the UK. All radiology departments with an approved lead for audit registered with the Royal College of Radiologists were invited to participate in this retrospective audit. The first 50 consecutive patients (25 surgical, 25 non-surgical) who underwent emergency abdominal CT for non-traumatic abdominal pain in 2013 were included. Statistical analyses were performed to identify organisational and report/patient-related variables that might be associated with major discrepancy. RESULTS One hundred and nine (58%) of 188 departments supplied data to the study with a total of 4,931 patients (2,568 surgical, 2,363 non-surgical). The audit standard for provisional report major discrepancy was achieved for registrars (target <10%, achieved 4.6%), for on-site consultants (target <5%, achieved 3.1%) and consultant addendum (target <5%, achieved 2.9%). Off-site reporters failed to meet the standard target (<5%, achieved 8.7% overall and 12.7% in surgical patients). The standard for patients coming to harm was not met in the surgical group (target <1%, achieved 1.5%) and was narrowly missed overall (target <1%, achieved 1%). CONCLUSION This study should be used to provide impetus to improve aspects of out-of-hours CT reporting. Clear benefits of CT interpretation/review by on-site and more senior (consultant) radiologists have been demonstrated.

Abstract
INTRODUCTION We aim to describe changes in exercise habits and barriers to physical activity over 5 years in menopausal women at low-intermediate risk for cardiovascular disease. MATERIALS AND METHODS Women in the Stress Echocardiography in Menopausal Women at Risk for Coronary Artery Disease trial were prospectively enrolled in a multisite study from 2004 to 2007. Inclusion criteria were as follows: peri- and postmenopausal women with symptoms and/or risk factors for cardiovascular disease resulting in referral for stress echocardiography. A questionnaire, which assessed details of medical history, physical activity, and body mass index (BMI), was administered at baseline and 5 years. RESULTS 216 menopausal women (62.5% hypertensive, 15.3% diabetic, 52.3% prior or current smokers) were studied. At baseline, age was 54.9 ± 4.8 years, BMI was 30.7 ± 6.4 kg/m2, and Framingham risk score was 4.05% ± 3.76%. One hundred women (46.3%) were obese, 79 (36.6%) overweight, and 37 (17.1%) had a normal BMI. Women changed their self-reported aerobic exercise patterns in similar patterns regardless of their BMI at baseline. There was low participation in strength training among all women. Mean BMI decreased by 0.12 kg/m2 in obese women and increased by 1.63 kg/m2 in normal BMI women at 5 years (p < 0.0001). CONCLUSION These data suggest that women can increase their level of physical activity regardless of BMI and that overweight or obese status is not a barrier to initiating an aerobic, nonaerobic, or strength training exercise routine.

Abstract
During a 72 h field test, two groups of elite, “ranger type” soldiers were evaluted five times (during the first 8 h, after 30 h of continuous field duty, after a rest period, after 30 more h of continuous field duty, and after a second rest). One group (7 soldiers) received two rests of 3 h each. The second group (6 soldiers) received two rests of 6 h each. Five military tasks (map reading, decoding messages, vehicle/aircraft recognition, assembly and disassembly of the M-16 rifle, and preparation of an AN/PRC radio for operation) were used. These tasks were considered by the commander to be representative of duties that the soldiers would do and were considered to be completely familiar to the soldiers. In addition, a peg into pegboard task and a subjective evaluation of fatigue questionnaire were given. There was no significant effect of time or difference between the two groups. The soldiers completed these tasks of short duration (less than 3 min) without decreasing performance—even after extended periods of sleep loss. These performance results occurred even though subjectively the soldiers reported they were tired.
