BACKGROUND Laser-Doppler imaging (LDI) of cutaneous blood flow is beginning to be used by burn surgeons to predict the healing time of burn wounds; predicted healing time is used to determine wound treatment as either dressings or surgery. In this paper, we do a statistical analysis of the performance of the technique. METHODS We used data from a study carried out by five burn centers: LDI wa...

One common dichotomy faced in recommender systems is that explicit user feedback -in the form of ratings, tags, or user-provided personal informationis scarce, yet the most popular source of information in most state-of-the-art recommendation algorithms, and on the other side, implicit user feedback such as numbers of clicks, playcounts, or web pages visited in a sessionis more frequently avail...

introduction: in this paper, a novel complexity measure is proposed to detect dynamical changes in nonlinear systems using ordinal pattern analysis of time series data taken from the system. epilepsy is considered as a dynamical change in nonlinear and complex brain system. the ability of the proposed measure for characterizing the normal and epileptic eeg signals when the signal is short or is...

A large number of previous studies have explored the clinical and radiological outcomes of anterior cervical corpectomy and fusion (ACCF); however, dysphagia after ACCF has been ignored in previous studies and the incidence, severity, and duration of dysphagia after ACCF remains unknown at present. A total of 297 patients who underwent ACCF were included in this study, dysphagia was evaluated a...

BACKGROUND AND PURPOSE Most large acute stroke trials have been neutral. Functional outcome is usually analyzed using a yes or no answer, eg, death or dependency versus independence. We assessed which statistical approaches are most efficient in analyzing outcomes from stroke trials. METHODS Individual patient data from acute, rehabilitation and stroke unit trials studying the effects of inte...

BACKGROUND AND AIM Focus on screening for cognitive impairment has to be given particular importance because of the rising older adult population. Thus, this study aimed to develop and assess a brief screening tool consisting of ten items that can be self-administered by community dwelling older adults (TUA-WELLNESS). METHODOLOGY A total of 1,993 noninstitutionalized respondents aged 60 years...

Though a reduced flush response to niacin has been found in schizophrenic patients, whether it is a vulnerability indicator to schizophrenia remains little known. We aimed to examine the familial aggregation in niacin flush response among schizophrenic patients and their nonpsychotic relatives. In a sample of 153 schizophrenia probands, 217 parents, 70 siblings, and 94 normal subjects, 3 concen...
