Cardiovascular responses to dynamic and static upper-body exercise in a cold environment in coronary artery disease patients
2021
Abstract Purpose Upper-body exercise performed in a cold environment may increase cardiovascular strain, which could be detrimental to patients with coronary artery disease (CAD). This study compared cardiovascular responses of CAD patients during graded upper-body dynamic and static exercise in cold and neutral environments. Methods 20 patients with stable CAD performed 30 min of progressive dynamic (light, moderate, and heavy rating of perceived exertion) and static (10, 15, 20, 25 and 30% of maximal voluntary contraction) upper body exercise in cold (− 15 °C) and neutral (+ 22 °C) environments. Heart rate (HR), blood pressure (BP) and electrocardiographic (ECG) responses were recorded an…
Effects of caffeine on neuromuscular function in a non‐fatigued state and during fatiguing exercise
2020
New findings What is the central question of the study? What are the effects of caffeine on neuromuscular function in a non-fatigued state and during fatiguing exercise? What is the main finding and its importance? In a non-fatigued state, caffeine decreased the duration of the silent period evoked by transcranial magnetic stimulation. Caffeine-induced reduction of inhibitory mechanisms in the central nervous system before exercise was associated with an increased performance. Individuals who benefit from caffeine ingestion may experience lower perception of effort during exercise and an accelerated recovery of M-wave amplitude postfatigue. This study elucidates the mechanisms of action of …
Newborn Infant Parasympathetic Evaluation Index for the Assessment of Procedural Pain in Nonanesthetized Infants: A Multicenter Pilot Study
2020
Abstract Objective The aim of this study is to evaluate the ability of the Newborn Infant Parasympathetic Evaluation (NIPE) index to detect the response to nociceptive stimuli in nonanesthetized infants and to compare these results to simultaneous scoring by behavioral scales. Study Design Thirty-six nonanesthetized infants admitted to neonatal/pediatric intensive care unit (N/PICUs) were enrolled to the study. Due to faulty records of the data, three patients had to be excluded. To detect pain caused by noxious stimuli, the heart-rate-variability-derived NIPE index and behavioral pain scales designed for measuring procedural pain in nonverbal children were used. Results Forty-one painful e…
The MITOS system predicts long-term survival in amyotrophic lateral sclerosis
2015
ObjectiveThe choice of adequate proxy for long-term survival, the ultimate outcome in randomised clinical trials (RCT) assessing disease-modifying treatments for amyotrophic lateral sclerosis (ALS), is a key issue. The intrinsic limitations of the ALS Functional Rating Scale-Revised (ALSFRS-R), including non-linearity, multidimensionality and floor-effect, have emerged and its usefulness argued. The ALS Milano-Torino staging (ALS-MITOS) system was proposed as a novel tool to measure the progression of ALS and overcome these limitations. This study was performed to validate the ALS-MITOS as a 6-month proxy of survival in 200 ALS patients followed up to 18 months.MethodsAnalyses were performe…
Interactive computerized morphometric analysis for the differential diagnosis between dysplasia and well differentiated adenocarcinoma of the prostate
1989
To distinguish prostatic dysplasia (or adenosis) from well differentiated adenocarcinoma on transrectal needle biopsy, a morphometric study was conducted on 20 cases of adenosis and 20 cases of well differentiated adenocarcinoma of the prostate. About 100 cells for each patient were analyzed by means of a computerized image analyzer, and mean nuclear diameter, mean nuclear area, mean form factor and number of cells in eight classes of nuclear diameter were studied. The best predictors of malignancy (evaluated by means of Receiver Operating Characteristics curves) were mean nuclear area greater than 28 mu2, presence of more than 5% of cells with nuclear diameter greater than 6.15 mu, and mea…
Norwegian version of the Nutritional Form for the Elderly: sufficient psychometric properties for performing institutional screening of elderly patie…
2009
The objective of this study was to test if the Norwegian version of the nutritional screening instrument entitled Nutritional Form for the Elderly (NUFFE-NO) demonstrates sufficient evidence of reliability and validity, including sensitivity and specificity, when applied to a select group of elderly hospital patients. The hypothesis was that NUFFE-NO has sufficient psychometric properties to be used as a screening instrument. The model used for the testing procedure was designed to test reliability (homogeneity and stability) and validity (criterion-related, concurrent validity, and construct validity) including sensitivity and specificity in a cross-sectional study. One-hundred fifty-eight…
Evaluation of the psychometric properties of “the Norwegian screening test for dyslexia”
2018
The aim of this study was to develop and investigate the psychometric properties of a screening protocol for Norwegian students in upper secondary school. The protocol was designed to assess skills that are at stake in dyslexia. It was administered to 232 students. In the absence of a “gold standard,” comparisons were made between students who reported normal literacy skills (n = 184) and literacy problems (n = 48). Significant group differences were found across all areas. Logistic regression and receiver operating characteristic curve analyses demonstrated good discriminatory power. The screening protocol met the standards for reliability and validity. It has the potential to be a useful …
Compliance and Pulse Wave Velocity Assessed by MRI Detect Early Aortic Impairment in Young Patients With Mutation of the Smooth Muscle Myosin Heavy C…
2008
Purpose To evaluate aortic elasticity with MRI on young asymptomatic individuals with mutation of the smooth muscle myosin heavy chain in whom aortic enlargement is not present. Materials and Methods Aortic compliance, aortic distensibility, and pulse wave velocity (PWV) were semiautomatically measured from MRI in 8 asymptomatic subjects having a mutation of the MYH11 gene (M+) and 21 nonmutated relatives (M−) of similar age, sex, and blood pressure characteristics. Results Despite a similar aortic diameter in both groups, the aortic compliance and distensibility were significantly lower in M+ subjects compared with M− (0.84 ± 0.33 versus 2.03 ± 0.54 mm2/mmHg, 1.18 ± 0.62 10−3 versus 5.11 ±…
Mental health prevalence and predictors among university students in nine countries during the COVID‑19 pandemic: a cross‑national study
2021
The student population has been highly vulnerable to the risk of mental health deterioration during the coronavirus disease (COVID-19) pandemic. This study aimed to reveal the prevalence and predictors of mental health among students in Poland, Slovenia, Czechia, Ukraine, Russia, Germany, Turkey, Israel, and Colombia in a socioeconomic context during the COVID-19 pandemic. The study was conducted among 2349 students (69% women) from May-July 2020. Data were collected by means of the Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-8), Perceived Stress Scale (PSS-10), Gender Inequality Index (GII), Standard & Poor's Global Ratings, the Oxford COVID-19 Government Respon…
Relationship between Psychophysical Measures of Retinal Ganglion Cell Density and In Vivo Measures of Cone Density in Glaucoma.
2017
Purpose Considerable between-individual variation in retinal ganglion cell (RGC) density exists in healthy individuals, making identification of change from normal to glaucoma difficult. In ascertaining local cone-to-RGC density ratios in healthy individuals, we wished to investigate the usefulness of objective cone density estimates as a surrogate of baseline RGC density in glaucoma patients, and thus a more efficient way of identifying early changes. Design Exploratory cohort study. Participants Twenty glaucoma patients (60% women) with a median age of 54 years and mean deviation (MD) in the visual field of –5 dB and 20 healthy controls (70% women) with a median age of 57 years and a mean…
