زمینه و هدف : اپیدمی جهانی سل منجر به 2 میلیون مورد مرگ و9 میلیون موارد جدید بیماری در سال میشود. اکثریت بیماران مبتلا به سل در کشورهای در حال توسعه زندگی می کنند،که در این کشورها تشخیص سل بر اساس مشخص شدن باسیل اسید فاست بر روی گستره های آماده شده خلط با میکروسکوپ نوری ساده داده می شود. تشخیص بوسیله میکروسکوپ در کشورهایی که اندمیک برای سل هستند ویژگی بالایی دارد،ولی حساسیت نسبتا پایینی دارد ...
Background and Objective: According to the complications of dementia, its screening is important in elderly stage. Dementia screening tests need to have acceptable sensitivity and specificity. This study aimed at determining the cut-off point of the Persian version of Clinical Dementia Rating (P-CDR) and testing its diagnostic accuracy in the early detection of dementia among the elderly....
Objectives: The authors of this paper hypothesized that vibration stimulation applied by a vibratory orthosis improves balance in patients with Parkinson’s disease (PD). In this study we evaluate this hypothesis. Methods & Materials: Fourteen PD patients (12 male and 2 female) with mean age of 59.9±9.1 (±SD) years were participated in this cross- sectional study. Using Biodex balance system,...
The present study was designed to develop a preliminatory cognitive screeting test battery for differentiating brain damaged patients, from psychiatric patients and normal subjects.Based on previous researches, the items scales, administraion and scoring instructions for the test battery were prepared. The test included the following scales: attention, memory, construction ability, receptive la...
Psychophysical tests of S-cone contributions to temporal ON- and OFF-channels were conducted. Detection thresholds for S-cone modulation were measured with two kinds of test stimuli presented on a CRT: a rapid-on sawtooth test and a rapid-off sawtooth test, assumed to be detected differentially by temporal ON- and OFF-channels, respectively. S-cone related ON- and OFF-temporal responses were se...
BACKGROUND Using Monte Carlo simulations, we compare different methods (maximizing Youden index, maximizing mutual information, and logistic regression) for their ability to determine optimum binary cut-off thresholds for a ratio-scaled diagnostic test variable. Special attention is given to the stability and precision of the results in dependence on the distributional characteristics as well a...
background: rupture of fetal membranes can occur at any gestational age. premature rupture of membranes (prom) means rupture of fetal membranes before the onset of labor. objective: the purpose of this study was to evaluate and compare the reliability of the vaginal washing fluid urea and creatinine for the diagnosis of prom and to determine cut-off values. materials and methods: a total of 179...
Background and Aim: Vitamin D has a basic role in bone development and metabolism. Regarding high prevalence of vitamin D deficiency in Iran, we aimed to investigate its point prevalence in Arak, Iran and determine a cut-off point for vitamin D deficiency in the region. Materials and Methods: In a cross-sectional study,420 adolescents (220 girls, 200 boys) aged 10-16 years old were selected usi...
OBJECTIVE The number of functionally impaired drivers being assessed is increasing the urgency to develop a standardized off-road driver assessment battery. We examined the validity of the Road Law and Road Craft Test (RLRCT) and a version of the Melbourne Slide Test to determine whether they should be included in the Occupational Therapy Driver Off-Road Assessment (OT-DORA) battery, which is u...
The diagnostic performance of the widely-used Cervista HPV HR test was compared to the Hybrid Capture 2 (HC2) test in a Dutch population-based cervical cancer screening program. In 900 scrapings of women with normal cytomorphology, specificity was 90% (95%CI: 87.84-91.87) for the Cervista HPV HR test and 96% (95%CI: 94.76-97.37) for the HC2 test with 93% agreement between both tests (κ = 0.5, p...
