Human epididymis protein 4 (HE4) levels inversely correlate with lung function improvement (delta FEV1) in cystic fibrosis patients receiving ivacaftor treatment

Background

We have recently shown that human epididymis protein 4 (HE4) levels correlate with the severity of cystic fibrosis (CF) lung disease. However, there are no data on how HE4 levels alter in patients receiving CFTR modulating therapy.

Current treatment of thoracic empyema in adults

Experiences obtained with 400 cases of thoracal empyema are described. The fact that the rate of lethality was 18.7% until present points out to the severity of the disease. The semi-conservative therapeutical methods used by the author (drainage, drainage and pleura lavage, pleura lavage and thoracoscopy, balance drainage) are presented. With their sensibly more frequent use the rate of operation could be reduced by 8% (from 36.5% to 28.5%) and the lethality rate by 7.6% (from 18.7% to 11.1). Further improvement of the results may be expected of the increased number of early detection (basic care), concentration of empyemic patients in special institutes (departments, wards) and due to it of a more efficient special treatment of uniform contemplation.     

Bacterial lipase and high-fat diets in canine exocrine pancreatic insufficiency: A new therapy of steatorrhea?

BACKGROUND & AIMS: Nutrients and properties of lipases affect survival of lipolytic activity during aboral gastrointestinal transit. Whether different doses and formulations of bacterial lipase and diets affect steatorrhea was tested in pancreatic-insufficient dogs. METHODS: A dose of 0-600,000 IU of powdered and 135,000 and 300,000 IU of liquid bacterial lipase was given with a standard meal to 5 dogs with ligated pancreatic ducts. In 4 dogs, 0 or 300,000 IU (normal 6-hour postprandial amount) of powder bacterial lipase was also given with five meals containing 850 kcal with different nutrient caloric densities (mixture design). Coefficients of fat absorption during 72- hour fecal balance studies were used to assess treatments. RESULTS: With the standard meal, powder bacterial lipase reduced steatorrhea in a dose-dependent manner (P = 0.03), and 135,000 and 300,000 IU of the liquid form decreased steatorrhea more than powder bacterial lipase (P = 0.017 and 0.057, respectively). Coefficients of fat absorption with 300,000 IU of powder bacterial lipase correlated (r2 = 0.79; P < 0.001) with increasing proportions of fat calories in diets. CONCLUSIONS: Liquid bacterial lipase decreases steatorrhea more than powder, and 300,000 IU of powder bacterial lipase ingested with high-fat meals corrects canine pancreatic steatorrhea. The combination of adequate mixing of small amounts (milligrams) of bacterial lipase and high-fat meals abolishes canine steatorrhea and may abolish human pancreatic steatorrhea.

Off-the-shelf audit: is it feasible?

Increasing interest in audit in the health service has focused attention on the tools and methods used to achieve it. These can be extremely expensive, so a tendency to opt for off-the-shelf packages has developed. This article reviews how one such instrument, The Central Nottinghamshire Psychiatric Nursing Audit, has been used in two settings over the past three years, with particular emphasis on its cost-effectiveness.     

Nickel- and cadmium-induced fetal myocardial changes in the mouse: the hazards of cigarette smoke in pregnancy

The prolonged effect of nickel chloride and cadmium chloride on the rat fetal myocardium was studied experimentally administered to the pregnant mother through a gastric tube in doses of 12.5 mg/b. wt. It could be demonstrated that, due to nickel administration, changes simulating cardiomyopathy and severe mitochondrial lesions developed and the number of collagenous fibres and glycogen granules accumulated, while as a result of cadmium chloride administration, changes were apparent mainly in the endothelial cells, but with simultaneous mitochondrial impairments, too. Nickel and cadmium are contained by cigarette smoke. Based on experimental studies, authors propose new arguments on the damaging effect of smoking of pregnant women.
