Intense and continuous physical training in sports is related with psychological and physiological stress, affecting the health and well-being of athletes. The development of non-invasive sampling methodologies is essential to consider sweat as a potential biological fluid for stress biomarker assessment. In the current work, the identification in sweat samples of potential molecules that may be used as stress biomarkers was pursued.
A sweat pool sample from football players after a 90-min intense training game was studied.
An analysis method using liquid chromatography with detection by tandem mass spectrometry (LC-MSMS) to attain a screening profile of sweat composition is presented. The major focus was on neurotransmitters (e.g. monoamines and metabolites) and other biological molecules related with physical training, such as precursors of biogenic amines (phenylaniline, tyrosine, etc.).
This study allowed the identification of small biomolecules, neurotransmitters and other related molecules in sweat that are potentially associated with stress conditions. The developed methodology intends to contribute to the assessment and study of physical and psychological stress biomarkers related with intense sports using non-invasive methods.

Intracranial capillary hemangiomas (ICHs) have a natural history and behavior that is very different from intracranial cavernous malformations. Paeoniflorin The literature is not consistent as to the best management strategy for ICHs.
Our patient is a 40-day-old male infant who presented with progressive increase in head circumference and multiple cutaneous capillary and ICHs. Obstructive hydrocephalus necessitated urgent cerebrospinal fluid (CSF) diversion, but no other surgical intervention was pursued due to the high risk-to-benefit ratio. Paeoniflorin Paeoniflorin All intracranial lesions spontaneously regressed by 11 years of age, albeit at a slower speed than the cutaneous lesions, with no functional or cognitive sequelae. We conducted a comprehensive literature review and provided a summary of all reported ICH cases.
Asymptomatic patients with ICHs are best approached with close follow-up and serial imaging studies as the potential for spontaneous regression is relatively high. Patients with isolated lesions or unclear diagnoses may benefit from a stereotactic biopsy, and surgical resection should be reserved for symptomatic lesions only.

The purpose of this study is to report a new mini-invasive technique to remove an intracranial bullet in a child by using O-arm for intraoperative neuronavigation.
A 14-year-old refugee boy had suffered a shooting injury 4years earlier. O-arm imaging-assisted neuronavigation during craniotomy was performed in order to remove a bullet from the intracranial space in a paediatric patient.
Navigation using O-arm is a feasible method in removing a foreign material in a child and gave an accurate location of the bullet in the adopted surgical operation position without significant imaging artefacts.

This study investigated whether performing kidney ultrasound (KUS) only in children presenting either a pathogen other than E. coli at their first febrile urinary tract infection (fUTI) or experiencing fUTI recurrence would increase missed diagnoses of kidney anomalies.
Patients aged 2-36 months with fUTI who underwent KUS evaluation from 2 January 2013 to 31 June 2018 were enrolled. link2 Cystourethrography was performed after pathological KUS or recurring fUTIs. Thereafter, we retrospectively assessed the detection rate of kidney anomalies through performing KUS only in patients with atypical pathogen at first fUTI or with recurring fUTIs.
In 263 patients included, the isolated pathogen was E. coli in 223 cases (84.8%) and atypical in 40 cases (15.2%). link3 KUS detected kidney anomalies in 14/223 (6.3%) of fUTIs caused by E. coli and in 11/40 (27.5%) of fUTIs caused by an atypical pathogen (OR 5.5, 95%CI 2.5-14.5). Cystourethrography was performed in 40 patients and vesicoureteral reflux (VUR) found in 20 cases. link2 None of the high grade VUR diagnoses or other kidney anomalies would have been lost through a different diagnostic protocol that required the presence of an atypical pathogen at the first fUTI or a fUTI recurrence to perform the KUS.
A diagnostic protocol that requires presence of an atypical pathogen at the first fUTI or a second episode of fUTI to perform the KUS would allow a reduction in the number of negative ultrasounds with a negligible risk of missed diagnoses of kidney anomalies.

The use of diuretics in patients whose kidney function is immature necessitates a thorough knowledge of renal developmental physiology and pathophysiology. This review presents the basic aspects of body fluid homeostasis in the neonate, discusses the development of kidney function, and describes the mechanisms involved in electrolyte and water reabsorption along the nephron. link3 Diuretics are then classified according to the site of their action on sodium reabsorption. The use of diuretics in sodium-retaining states, in oliguric states, in electrolyte disorders, and in arterial hypertension, as well as in a few specific disorders, is presented. Common and specific adverse effects are discussed. Recommended dosages for the main diuretics used in the neonatal period are given. New developments in diuretic therapy are briefly mentioned.
Quantitative MRI (qMRI) methods provide versatile neuroradiological applications and are a hot topic in research. The degree of their clinical implementation is however barely known. This survey was created to illuminate which and how qMRI techniques are currently applied across Europe.
In total, 4753 neuroradiologists from 27 countries received an online questionnaire. Demographic and professional data, experience with qMRI techniques in the brain and head and neck, usage, reasons for/against application, and knowledge of the QIBA and EIBALL initiatives were assessed.
Two hundred seventy-two responders in 23 countries used the following techniques clinically (mean values in %) DWI (82.0%, n = 223), DSC (67.3%, n = 183), MRS (64.3%, n = 175), DCE (43.4%, n = 118), BOLD-fMRI (42.6%, n = 116), ASL (37.5%, n = 102), fat quantification (25.0%, n = 68), T2 mapping (16.9%, n = 46), T1 mapping (15.1%, n = 41), PET-MRI (11.8%, n = 32), IVIM (5.5%, n = 15), APT-CEST (4.8%, n = 13), and DKI (3.3%, n = 9). link2 The mos advanced imaging could be promoted through an increase in technical support and training of both doctors and technicians.
• Neuroradiologists endorse the use of qMRI techniques as they subjectively improve diagnostic accuracy. • Clinical implementation is highly variable between countries, techniques, and indications. • The use of advanced imaging could be promoted through an increase in technical support and training of both doctors and technicians.
Direct toxic effects of transthyretin amyloid in patient plasma upon cardiomyocytes are discussed. However, no data regarding the relevance of this putative effect for clinical outcome are available. In this monocentric prospective study, we analyzed cellular hypertrophy after phenylephrine stimulation in vitro in the presence of patient plasma and correlated the cellular growth response with phenotype and prognosis.
Progress in automated microscopy and image analysis allows high-throughput analysis of cell morphology. Using the InCell microscopy system, changes in cardiomyocyte's size after treatment with patient plasma from 89 patients suffering from transthyretin amyloidosis and 16 controls were quantified. For this purpose, we propose a novel metric that we named Hypertrophic Index, defined as difference in cell size after phenylephrine stimulation normalized to the unstimulated cell size. Its prognostic value was assessed for multiple endpoints (HTX death/heart transplantation; DMP cardiac decompensat risk factor for adverse cardiac events in ATTR patients.
COVID-19 has caused considerable morbidity and mortality worldwide and cardiac involvement has been reported during infection. The short-term cardiac outcome in survivors of COVID-19 is not known.
To examine the heart of patients who survived COVID-19 and to compare the cardiac outcome between patients who recovered from mild-to-moderate or severe illness.
With use of ECG and echocardiography, we examined the heart of 105 patients who had been hospitalized with COVID-19 and were consecutively recruited after hospital discharge while attending follow-up visits. Survivors of COVID-19 were compared with 105 matched controls. We also compared the cardiac outcome and lung ultrasound scan between COVID-19 patients who had mild-to-moderate or severe illness.
Cardiac data were collected a median of 41days from the first detection of COVID-19. Symptoms were present in a low percentage of patients. In comparison with matched controls, no considerable structural or functional differences were observed in the heam COVID-19 do not have considerable cardiac sequelae.Rat-inbred strains are essential as scientific tools. We have analyzed the publicly available genome sequences of 40 rat-inbred strains and provide an overview of sequence variations leading to amino acid changes in protein-coding genes, premature STOP codons or loss of STOP codons, and short in-frame insertions and deletions of all protein-coding genes across all these inbred lines. We provide an overview of the predicted impact on protein function of all these affected proteins in the database, by comparing their sequence with the sequences of the rat reference strain BN/SsNHsdMcwi. We also investigate the flaws of the protein-coding sequences of this reference strain itself, by comparing them with a consensus genome. These data can be retrieved via a searchable website (Ratpost.be) and allow a global, better interpretation of genetic background effects and a source of naturally defective alleles in these 40 sequenced classical and high-priority rat-inbred strains.Hundreds of oil wells were drilled along Oil Creek in Pennsylvania in the mid-1800s, birthing the modern oil industry. link3 No longer in operation, many wells are now classified as abandoned, and, due to their age, their locations are either unknown or inaccurately recorded. These historic-well sites present environmental, safety, and economic concerns in the form of possible methane leaks and physical hazards. Airborne magnetic and LiDAR surveys were conducted in the Pioneer Run watershed in Oil Creek State Park to find abandoned wells in a historically significant but physically challenging location. Wells were drilled in this area prior to modern geolocation and legal documentation. Although a large number of old wells were abandoned summarily without remediation of the site, much of the land area within Oil Creek State Park is now covered in trees and dense underbrush, which can obscure wellheads. The thick vegetation and steep terrain limited the possibility of ground-based surveys to easily find well sites for methane emissions studies.
