Sarcopenia, resulting from skeletal muscle loss, is a serious concern in children, for whom nutrition and physical activity are essential for growth. In sarcopenia research, the skeletal muscle mass i...
We conducted a single-centre, retrospective, cross-sectional study and included patients aged 1-17 years who underwent abdominal CT at Chiba University Hospital from 2007 to 2020. Patients with chroni...
We analysed the abdominal CT images of 593 children (male: n = 335, female: n = 258) and generated curves predictive for the 5th, 25th, 50th, 75th, and 95th percentiles for each compartment of aSMA by...
We generated quantile regression curves for three aSMA compartments obtained from cross-sectional CT images and established reference values in children. PSMA values were most strongly correlated with...
This study aims to assess psychometric properties of the Hungarian PROMIS-29+2 profile measure and provide general population reference values for Hungary....
An adult general population sample (n = 1700) completed PROMIS-29+2 v2.1 in an online survey. The following psychometric properties were assessed: floor and ceiling effect, convergent validity with SF...
Depending on scale orientation, high floor or ceiling effects were observed for all domains (25.2-60.7%) except for sleep disturbance. McDonald's omega for domains ranged from 0.87-0.97. Unidimensiona...
The Hungarian PROMIS-29+2 shows satisfactory psychometric properties; however, the sleep disturbance domain substantially underperforms that requires further attention. Population reference values wer...
The oldest old, defined as those aged 90 or over, is now the fastest-growing population sector. This study aimed to determine reference values for several physical performance measures (PPMs) among 90...
We used the Septuagenarians, Octogenarians, and Nonagenarians Investigation with Centenarians (SONIC) study data from 2010 to 2018. The study subjects were 70, 80, and 90-year-olds in the target area ...
The simple mean ± standard deviation (SD) for the 90-year-old respondents were in men, 24.1 ± 5.4 kg in hand grip strength, 0.80 ± 0.22 m/s in usual gait speed, 17.2 ± 6.73 s in 5times chair stand, 5....
Our study yielded inclusive sex-specific reference values and appraisal standards for major physical performance measures not certified as requiring long-term care, community-dwelling, oldest old Japa...
T1 and T2 mapping techniques on cardiovascular magnetic resonance (CMR) provide insights into the myocardial tissue characterisation. We sought to establish the normal reference values of native T1 an...
To determine if the United States reference values of the Bayley Scales of Infant and Toddler Development, version III motor scale are suitable for Surinamese infants, we assessed 151 healthy infants ...
New oscillometry devices allowing quantification of respiratory function using tidal breathing are commercially available, but reference equations are lacking for the multiethnic Canadian pediatric po...
We conducted a prospective cross-sectional study of healthy children carefully selected for absence of asthma, atopy, tobacco smoke, obesity, prematurity, and recent respiratory infection. Triplicate ...
Of 306 children randomized, valid and reproducible results on ≥1 signal were obtained in 299 (98%) multiethnic (69% Caucasians: 8% Black: 23% Others) children aged 3-17 years, 91-189 cm tall. Standing...
Valid reproducible oscillometry measurements are highly feasible in children aged 3 years and older. Device-specific reference equations, valid for our multiethnic population, are derived....
The primary objective of this study was to examine the glenohumeral subluxation index (GHSI) in a large general population cohort and to define reference values. Glenohumeral subluxation is important ...
GHSI according to Walch was measured on bilateral magnetic resonance imaging of 3004 participants of the Study of Health in Pomerania (SHIP, aged 21-90 years). SHIP drew a sample of the adult general ...
A reference range between 42% and 55% for men with a mean of 49% ± 4% was defined, while the upper reference limit for women was 1% higher (mean, 50% ± 4%). Age was inversely associated with the GHSI ...
The reference values for GHSI were expanded to a range of 42%-57% on magnetic resonance imaging. Several associations between GHSI and anthropometric properties are present. According to these associa...
Cerebro spinal fluid (CSF) parameters (white blood cell count, protein, glucose) in the diagnosis of neonatal bacterial meningitis....
To report the reference range of CSF parameters (white blood cell count, protein, glucose) in both term and preterm infants....
This was a single center retrospective study over a period of 5 years (2015-2020). We included infants aged 0-3 months admitted to the neonatal unit and infants ≤28 days attending pediatric acute care...
We identified a total of 518 CSF samples, with 232 CSF samples available for final analysis. 54% of excluded samples were traumatic. Median birth gestation and birth weight of the study cohort were 38...
We have provided a reference range of CSF parameters in neonates without meningitis. CSF WBC count between preterm and term infants were similar with higher CSF protein content in preterm infants and ...
Assay of sex hormone binding globulin (SHBG), the main carrier protein for sexual steroids, is prescribed mainly by endocrinologists and performed in specialized laboratories. This study aimed to eval...
One hundred and forty sera were used to assess the analytic performance of the IDS kit. The coefficients of variation (CV%) for within- and between-run precision were calculated. The reference values ...
The new kit correlated strongly with the reference technique (R...
The performance of the IDS kit met the current recommendations and correlated strongly with the Cisbio method. The calculation of new sex-based reference values was needed to correctly classify patien...
Nerve ultrasound is useful in the diagnosis and follow-up of peripheral nerve disorders in children. The aim of this study was to explore and analyze the current literature on nerve cross-sectional ar...
We performed a systematic review and meta-analysis of studies that reported ultrasound measurements of the upper or lower limb nerves in healthy children through a search of Web of Science, PubMed, Em...
Sixteen studies with measurements of 10 nerves covering a total of 5149 nerves measured in 823 healthy children (445 boys and 378 girls) were included. Mean nerve CSA increased with age in the median ...
This meta-analysis provides robust reference values for nerve CSA at different sites in children, and this can inform clinical practice and assist in identifying nerve enlargement. Moreover, it identi...
