a standard breakfast was evaluated as a screening test (bt) for gestational diabetes in a case-control study. blood sugar (bs) was measured 1 hour after a breakfast that had 50gr simple sugar and was designed based on women preferences. in the same women glucose challenge test (gct, 50gr 1hour glucose screening test) was performed one week later in randomized sequential. cutoff values for both ...

background: waist circumference (wc) is an accurate and simple measure of abdominal obesity as compared to waist–hip ratio (whr). the aim of this study was to determine the correlation between body mass index (bmi) with wc and whr and suggest cutoff points for wc among rural malaysian adults. methods: a cross‑sectional study was conducted among 669 respondents from three villages in tanjung kar...

Background: Chest pain is the most common reason for patients to be referred to the emergency department of hospitals. This study was performed to compare the GRACE and TIMI scores in predicting important cardiovascular events in patients. Methods: This descriptive-analytical study was performed on 862 cardiac patients who were referred to the emergency department of Taleghani Hospital in Urmi...

The cutoff phenomenon describes a sharp transition in the convergence of an ergodic finite Markov chain to equilibrium. Of particular interest is understanding this convergence for the simple random walk on a bounded-degree expander graph. The first example of a family of bounded-degree graphs where the random walk exhibits cutoff in total-variation was provided only very recently, when the aut...

Simulations involving the Lennard-Jones potential usually employ a cutoff at r = 2.5σ. This communication investigates the possibility of reducing the cutoff. Two different cutoff implementations are compared, the standard shifted potential cutoff and the less commonly used shifted forces cutoff. The first has correct forces below the cutoff, whereas the shifted forces cutoff modifies Newton's ...

In a recent Letter tathe Editor (Clin. Chem. 27:505, 1981) we evaluated a new Ferritin Radioimmunoassay kit from Diagnostic Products Corp., Los Angeles, CA. In that letter we stated that a serum ferritin cutoff of 20 g/L appeared to separate normal values from those measured in iron-deficiency anemia. The manufacturer has recalibrated the standards in the assay, resulting in a shift in the gene...
