Background: Insomnia is the sleep disorder with highest incidence worldwide. It estimated that this condition increases risk of developing psychiatric, neurological, and cardiovascular problems. Due to this, it important have brief, reliable valid psychometric instruments allow health personnel their timely detection in first level centers. Objectives: Analyze properties Severity Index (ISI) it...

Regional cerebral blood flow (rCBF) was measured by the 133Xenon inhalation method in a selected group of 44 normal non-hospitalized, normotensive subjects aged 19 to 79 years. rCBF was computed as the initial slope index value (ISI). Advancing age was associated with significant reductions in the mean brain and mean hemispheric ISI as well as in individual ISI levels measured from all areas in...

OBJECTIVE To translate and validate the Michigan Incontinence Severity Index (M-ISI) for its use in Turkish-speaking women with urinary incontinence. METHODS The translation and cross-cultural adaptation were based on international guidelines. Content validity by content validity ratio/content validity index, internal consistency by Cronbach's alpha, test-retest reliability by Pearson's corre...

BACKGROUND We developed a simple and new insulin resistance index derived from a glucose clamp and a meal tolerance test (MTT) in Japanese patients with type 2 diabetes mellitus. METHODS Fifteen patients [mean age: 53 years, fasting plasma glucose (FPG) 7.7 mmol/L, HbA1c 7.1% (54 mmol/mol), body mass index 26.8 kg/m(2)] underwent a MTT and a glucose clamp. Participants were given a test meal ...

The use of animal models in diabetes research requires reliable tests for evaluation of insulin sensitivity and beta-cell function. Minipigs are being increasingly used in metabolic research, and the aim of this study was to compare different tests and indexes for evaluation of insulin sensitivity and beta-cell function in Göttingen minipigs. Hyperinsulinemic, isoglycemic clamp, intravenous (IV...

AIMS The recommended method for the international sensitivity index (ISI) calibration of whole blood point of care testing (POCT) prothrombin time (PT) systems was originally described by Tripodi et al in 1993 but is too complex and demanding. The present European Concerted Action on Anticoagulation (ECAA) study aimed to assess the reliability of simpler ISI calibration using lyophilised plasma...

BACKGROUND AND AIMS Nonalcoholic fatty liver disease (NAFLD) and polycystic ovary syndrome (PCOS) recognize obesity and insulin resistance (IR) as common pathogenic background. We assessed 1) whether PCOS is a risk factor for steatosis, and 2) the impact, in PCOS patients, of IR and hyperandrogenism on steatosis and fibrosis. METHODS We considered 202 consecutive Italian PCOS nondiabetic pati...

Serum profiles of lipids and/or liver enzymes are established markers for the estimation of insulin resistance and diabetic risk in the non-diabetic middle-aged population. To identify prediabetic markers in young subjects, 110 young male subjects (20-29 years of age) with normal glucose tolerance (NGT) were divided into two groups by median body mass index (BMI), <22.18 (n=55) and ≥22.18 (n=55...

OBJECTIVE To evaluate the impact of obesity and various phenotypes of polycystic ovary syndrome (PCOS) on the insulin sensitivity index (ISI) and insulin resistance (IR). METHODS ISI and IR from 273 women in four phenotypes of PCOS and control groups were evaluated retrospectively. RESULTS The ISI and the percentage of IR were not significantly different among discrete phenotypes of PCOS gr...

A 10 centre calibration was performed after six years to determine the international sensitivity index (ISI) of rTF/95 relative to RBT/90, and to assess any international normalised ratio (INR) bias compared with the original multicentre calibration. After exclusion of one outlying centre, the follow up calibration gave a mean ISI for rTF/95 of 0.99, which although a small difference, is signif...
