data envelopment analysis (dea) measures the relative efficiency of decision making units (dmus) with multiple inputs and multiple outputs. dea-based malmquist productivity index measures the productivity change over time. we propose a dynamic dea model involving network structure in each period within the framework a dea. we have previously published the network dea (ndea) and the dynamic dea ...

PURPOSE To investigate tear film optical quality dynamics by analyzing the postblink temporal changes of objective scatter index (OSI). METHODS A total of 109 myopic subjects without symptoms of dry eye and 32 myopic subjects diagnosed with dry eye disease were recruited in this cross-sectional study. The right eye for each subject was analyzed. Serial measurements of OSI were performed for 2...

BACKGROUND Chronic ankle instability (CAI) is attributed to functional instability driven by insufficient proprioception. However, it is not clear whether the deficits are related to global impaired performance or to specific decrease in ankle motor-control. The aim of this study was to assess the correlation between lower limb postural control and upper limb position sense among people with CA...

Objective: Current study evaluated the utility of total antioxidant status (TAS), oxidative stress index (OSI), oxidant (TOS), ischemia-modified albumin (IMA), and ratio (IMAR) as markers in autoimmune liver disease (AILD).
 Material Methods: The included a 66 AILD patients, 22 with hepatitis (AIH), 32 primary biliary cholangitis (PBC), 12 AIH/PBC overlap syndrome, 49 healthy controls. Ser...

Pada kasus berat, pneumonia COVID-19 terjadi perburukan secara cepat dan progresif yang menyebabkan ARDS. Pengukuran parameter oksigenasi seperti oxygenation index (OI) oxygen saturation (OSI) pada beberapa penelitian menunjukkan superioritas dibanding dengan rasio PaO2/FiO2 dalam menilai status derajat keparahan Penelitian ini bertujuan melakukan analisis faktor risiko OI, OSI, Rasio terhadap ...

PURPOSE To evaluate the repeatability and reproducibility of a double-pass instrument (OQASII, Visiomereics SL, Spain), which objectively measures overall optical quality of the human eyes. METHODS The right eye of 119 healthy subjects with best corrected visual acuity of 20/25 or better was included in this prospective, comparative, observational study. Two separate tests with OQASII were co...

OBJECTIVE To establish and validate a new system to define the severity of onychomycosis. The Onychomycosis Severity Index (OSI) score is obtained by multiplying the score for the area of involvement (range, 0-5) by the score for the proximity of disease to the matrix (range, 1-5). Ten points are added for the presence of a longitudinal streak or a patch (dermatophytoma) or for greater than 2 m...

BACKGROUND/AIM Occupational stress is a term used to define ongoing stress that is related to the workplace. The study was conducted to determine association of occupational stress index (OSI) and its aspects with arterial hypertension and lipid disorders using data from a cross-sectional survey of male professional drivers. METHODS The cross-sectional study was performed in 439 professional ...

BACKGROUND Serum anti-Mullerian hormone (AMH) is currently considered the best marker of ovarian reserve and of ovarian responsiveness to gonadotropins in in-vitro fertilization (IVF). AMH assay, however, is not available in all IVF Units and is quite expensive, a reason that limits its use in developing countries. The aim of this study is to assess whether the "ovarian sensitivity index" preci...

PURPOSE To evaluate the repeatability of measurements with a double-pass system. SETTING Rothschild Foundation, Paris, France. METHODS Eyes were separated into 2 control groups (<30 years old and >40 years), a post-refractive surgery group, and a cataract group. Measurements were performed using the Optical Quality Analysis System. The main outcome measures were the objective scattering ind...
