A randomized, embedded, pragmatic, Bayesian clinical trial examining clinical decision support for high flow nasal cannula management in children with bronchiolitis: design and statistical analysis plan.

Background: High flow nasal cannula (HFNC) has been increasingly adopted in the past 2 decades as a mode of respiratory support for children hospitalized with bronchiolitis. The growing use of HFNC despite a paucity of high-quality data regarding the therapy's efficacy has led to concerns about overutilization. We developed an electronic health record (EHR) embedded, quality improvement (QI) oriented clinical trial to determine whether standardized management of HFNC weaning guided by clinical decision support (CDS) results in a reduction in the duration of HFNC compared to usual care for children with bronchiolitis.

Impact of varying analytical methodologies on grain particle size determination.

The determination of particle size is an important quality control measurement for feed manufacturers, nutritionists, and producers. The current approved method for determining the geometric mean diameter by weight (d) and geometric standard deviation (S) of grains is standard ANSI/ASAE S319.4.

The Application of Nano-Sized Zero-Valent Iron for In Situ Remediation of Chlorinated Ethylenes in Groundwater: A Field Case Study.

In this paper, the authors present the pilot in situ application of nano zero-valent iron (nZVI) for effective remediation of groundwater in an industrial area contaminated by chlorinated ethylenes (CEs), which create a significant group of global environmental contaminants. This work covers the entire 1-year remediation process, including systematic laboratory tests and field application techniques for nZVI. The application was carried out in the area of a metal fabrication industrial facility in the Czech Republic.

[Personal experience with the Mono type of insulin--clinical study].

A multicentric study was conducted in March to September 1995 to test the effectiveness and tolerance of a new insulin series. A total of 281 diabetics above 15 years of age were followed up, 144 men and 137 women, mean age 63 years with a duration of diabetes from 0.5 to 51 years, without serious organ complications and capable to recognise symptoms of hypoglycaemia.

[Follow-up of newly diagnosed patients with diabetes in the Prague population. II. Changes in the group of new diabetics after a 2-year follow-up].

From the total number of 1551 new diabetics and patients with PGT 85 subjects died in the course of two years. Treatment was changed 118 times, failure of PAD treatment was recorded in 11 type 2 diabetics. Three patients originally classified as type 1 were later included in type 2.

[Follow-up of newly diagnosed patients with diabetes in the Prague population. I. Incidence of diabetes and disorders of glucose tolerance, methods of detection, complications].

The authors followed up the incidence of new cases of diabetes in nine Prague diabetological clinics, the way of manifestation of diabetes and its detection, age dependence, seasonal character and incidence of complications. The incidence of type 2 diabetes was 269, of type 1 2.3 and impaired glucose tolerance 27 per 100,000 population.

Evaluation of hepatocytes isolated by a nonperfusion technique in a prescreen for cytotoxicity.

Twenty-three chemicals, differing widely in cytotoxic (hepatotoxic) potency in vivo, were examined to determine their ability to release glutamic-oxaloacetic transaminase (GOT) from hepatocytes isolated by a nonperfusion method from rat liver. The test chemicals were carbon tetrachloride, chloroform, 1,1,2- and 1,1,1-trichloroethane, six bromobenzene analogs, tri-n-butyl tin, chlorpromazine, tetracycline, halothane, phenobarbital, L-ethionine, acetaminophen, thioacetamide, allyl alcohol, ethanol, ascorbic acid, dimethyl sulfoxide, and acetone. In all but two cases--thioacetamide and allyl alcohol--there was a good correspondence between chemicals active in the assay as now performed and those that elevate serum transaminase and cause liver injury on short-term exposure in vivo.
