Background: Several indirect calorimetry (IC) instruments are commercially available, but comparative validity and reliability data are lacking. Existing data are limited by inconsistencies in protocols, subject characteristics, or single-instrument validation comparisons. The aim of this study was to compare accuracy and reliability of metabolic carts using methanol combustion as the cross-labora

A system for local oscillator (LO) signal generation in 5G millimeter-wave (mmW) multi-antenna transceivers is presented. The system is modular with one phase locked loop (PLL) per antenna element transceiver, and a test circuit implemented in 28-nm fully depleted silicon on insulator (FD-SOI) CMOS features two such PLLs and a 491.52 MHz crystal oscillator (XO) generating a common frequency refere

Background: Suicide victims have been found to frequently suffer from mental disorders, often more than one, and comorbidity has also been found to be a risk factor for suicide. The aim of the present study was to determine the first disorder and possible subsequent disorders in suicide victims during their lifetimes and to compare their development with the development of mental and alcohol use d

Background: The Osborn or J-wave, an upright deflection of the J-point on the electrocardiogram (ECG), is often observed during severe hypothermia. A possible relation between Osborn waves (OW) and increased risk of ventricular arrhythmia has been reported. We sought to determine whether the level of targeted temperature management (TTM) following out-of-hospital cardiac arrest (OHCA) affects the

Background: Despite the presence of efferent neural pathways from the cortex to brainstem, evidence for cognitive inhibition and sensory gating on the auditory brainstem has been mixed. Some previous studies have suggested auditory brainstem responses (ABR) can be affected by cognitive load whereas others have not. Purpose: The present study explores if the ABR recorded from adults with normal hea

The first detailed chemical abundance analysis of the M-dwarf (M4.0) exoplanet-hosting star Ross 128 is presented here, based upon near-infrared (1.5-1.7 μm), high-resolution (R ∼ 22,500) spectra from the SDSS Apache Point Galactic Evolution Experiment survey. We determined precise atmospheric parameters T eff = 3231 ±100 K, log g = 4.96 ±0.11 dex and chemical abundances of eight elements (C, O, M

Objectives: To investigate the prevalence of obesity among different types of employment status in the Italian working population, and to examine associated risk factors. Material and Methods: Cross-sectional survey of 36 814 people that declared to have been occupied with the same type of contract for at least 5 years was analyzed. Multivariable logistic regression models were built considering w

Background: A varying response to cholinesterase inhibitor (ChEI) treatment has been reported among patients with Alzheimer’s disease (AD). Whether the individual-specific response directly affects time to nursing home placement (NHP) was not investigated. Objective: We examined the relationship between the 6-month response to ChEI and institutionalization. Methods: In a prospective, observational

Background: Treatment for cleft lip and/or palate (CL/P) involves a multidisciplinary team of experts who aim to improve ones’ appearance, health-related quality of life, and speech function. To appropriately measure outcomes in CL/P from the patient perspective, a CL/P-specific patient-reported outcome (PRO) instrument is needed. The CLEFT-Q is a self-report PRO instrument developed to evaluate t

Phthalates are ubiquitous in indoor environments, which raises concern about their endocrine disrupting properties. However, studies of human uptake from airborne exposure are limited. We studied the inhalation uptake and dermal uptake by air-to-skin transfer with clean clothing as a barrier of two deuterium-labelled airborne phthalates: particle-phase D4-DEHP (di-(2-ethylhexyl)phthalate) and gas-

Many biopharmaceuticals (BPs) are known to be immunogenic in the clinic, which can result in modified pharmacokinetics, reduced efficacy, allergic reactions and anaphylaxis. During recent years, several technologies to predict immunogenicity have been introduced, but the predictive value is still considered low. Thus, there is an unmet medical need for optimization of such technologies. The genera

Aims: We aimed to evaluate the impact of delay from diagnostic pre-hospital electrocardiogram (ECG) to wiring of the infarct-related vessel (ECG-to-wire) >120 minutes on cardiovascular magnetic resonance (CMR) markers of reperfusion success and clinical outcome in patients with ST-segment elevation myocardial infarction (STEMI). Methods and results: We included 1,492 patients in the analyses of cl

Background: Overnight fasting is often prolonged before scheduled surgery, and the extent of perioperative fluid replacement may influence outcome. In clinical practice, basic requirements are estimated at 1.2-2.0 mL·kg−1·h−1, but there is little contemporary clinical data on what deficits result from complete fasting. This prospective preclinical study was designed to determine total fluid loss d

Background: In the Swedish population aged between 50 and 64 years only 7.1% reach the recommended level of physical activity. Physical activity on prescription (PAP) has been used in Sweden since the beginning of the twenty-first century with moderate adherence of approximately 50%. Mindfulness seems to affect motivation to and satisfaction with physical activity. The aim is to test the feasibili

Background: Video capsule endoscopy (VCE) is a noninvasive method enabling excellent visualization of the small bowel (SB) mucosa. The aim of this study was to examine the impact and safety of VCE performed in children and adolescents with suspected or established Crohn’s disease (CD). Methods: A total of 180 VCE examinations in 169 consecutive patients conducted in 2003–14 in a single center were

NG2 cells, a fourth glial cell type in the adult mammalian central nervous system, produce oligodendrocytes in the healthy nervous tissue, and display wide differentiation potential under pathological conditions, where they could give rise to reactive astrocytes. The factors that control the differentiation of NG2 cells after focal cerebral ischemia (FCI) are largely unknown. Here, we used transge

BACKGROUND AND OBJECTIVE: Vitamin B6 plays a pivotal role in brain development and functioning. Differences in vitamin B6 homeostasis between preterm and term newborn infants have been reported. The authors sought to investigate whether B6 vitamers in cerebrospinal fluid (CSF) of preterm and term newborn infants are different. METHODS: B6 vitamer concentrations were determined in 69 CSF samples of

The disorders of serine biosynthesis are a group of inborn errors of metabolism characterised by congenital microcephaly, seizures and severe psychomotor retardation. Although these disorders are rare the prompt recognition of serine deficiency is important as these disorders are treatable. The diagnosis is based on decreased concentrations of serine in cerebrospinal fluid (CSF). It has previously
