Consensus statement addressing controversies and guidelines on pediatric urolithiasis.

Purpose: We aimed to investigate controversial pediatric urolithiasis issues systematically, integrating expert consensus and comprehensive guidelines reviews.

Methods: Two semi-structured online focus group meetings were conducted to discuss the study's need and content, review current literature, and prepare the initial survey. Data were collected through surveys and focus group discussions.

Sustainable Optimal Control for Switched Pollution-Control Problem with Random Duration.

Considering the uncertainty of game duration and periodic seasonal fluctuation, an -player switched pollution-control differential game is modeled to investigate a sustainable and adaptive strategy for players. Based on the randomness of game duration, two scenarios are considered in this study. In the first case, the game duration is a random variable, Tf, described by the shifted exponential distribution.

P-Wave Axis of Schoolchildren Who Were Once Breastfed.

Background: It has been known for decades that breastfeeding leads to a lower risk of asthma, respiratory infections, or metabolic syndrome at school age. In addition, evidence is now accumulating on the influence of breast milk on the shape, volume, or function of the heart and lungs. Within this field of research into the effects of breast milk on the structure of the heart and lungs, we have set out to analyze the differential electrocardiographic characteristics of schoolchildren who were once breastfed.

Evaluation of functional warm ischemia time during controlled donation after circulatory determination of death using normothermic regional perfusion (ECMO-TT): A prospective multicenter cohort study.

Background: Controlled donation after circulatory determination of death (cDCD) seems an effective way to mitigate the critical shortage of available organs for transplant worldwide. As a recently developed procedure for organ retrieval, some questions remain unsolved such as the uncertainty regarding the effect of functional warm ischemia time (FWIT) on organs´ viability.

Methods: We developed a multicenter prospective cohort study collecting all data from evaluated organs during cDCD from 2017 to 2020.

Multicenter comparative study of open, laparoscopic, and robotic pyeloplasty in the pediatric population for the treatment of ureteropelvic junction obstruction (UPJO).

Introduction: Dismembered open pyeloplasty described by Anderson and Hynes is the "gold standard" for the treatment of ureteropelvic junction obstruction. The aim of our study was to compare the results of open (OP) vs laparoscopic (LP) vs robotic (RALP) pyeloplasty.

Material And Methods: A multicenter prospective review was conducted of pyeloplasty surgeries performed at five high-volume centers between 2014 and 2018.

Outcomes and lessons learnt from practice of retrograde intrarenal surgery (RIRS) in a paediatric setting of various age groups: a global study across 8 centres.

Purpose: To analyse and report the practice, outcomes and lessons learnt from a global series of retrograde intrarenal surgery (RIRS) in a paediatric multicentre series.

Methods: A retrospective review of anonymized pooled data gathered globally from 8 centres in paediatric patients (≤ 18 years of age) who had renal stones and underwent RIRS from 2015 to 2020 was performed. Patient demographics, perioperative parameters, stone characteristics, complications and stone-free rate (SFR; defined as endoscopically stone free and/or residual fragments < 2 mm on follow up imaging) were analysed.

Evaluating the effect of expert elicitation techniques on population status assessment in the face of large uncertainty.

Population projection models are important tools for conservation and management. They are often used for population status assessments, for threat analyses, and to predict the consequences of conservation actions. Although conservation decisions should be informed by science, critical decisions are often made with very little information to support decision-making.

Emotional intelligence, resilience and personality traits neuroticism and extraversion: predictive capacity in perceived academic efficacy.

Background: Recent studies have shown the importance of promoting emotional intelligence and resilience, as well as knowing the personality (extraversion versus emotional instability or neuroticism) in both nursing students and nursing professionals, for better academic adherence, due to stressful situations derived from high academic and attendance requirements for healthcare practices in clinical settings. However, there is little research that analyzes the importance of the perceived academic effectiveness of university students and its relationship with the psychological variables of resilience, emotional intelligence and personality.

Objective: To analyse the relationships between perceived academic efficacy, emotional intelligence (EI), resilience and the personality factors of emotional instability and extraversion, as well as to observe the variables that predict perceived academic efficacy.

The effect of the Covid-19 Pandemic on pediatric urology.

Medical and surgical priorities have changed dramatically at the time of this pandemic. Scientific societies around the World have provided rapid guidance, underpinned by the best knowledge available, on the adaptation of their guidelines recommendations to the current situation. There are very limited scientific evidence especially in our subspecialty of pediatric urology.

Patient blood management in cardiac surgery: Results.

Objective: The main objective of the study was to evaluate the effect of implementing a blood-saving programme in patients undergoing elective cardiac surgery with an analysis of the transfusion rate and complications.

Materials And Methods: A single-centre, observational, retrospective, comparative study which included 604 consecutive patients older than 15 years old undergoing elective cardiac surgery. Two groups of patients were created according to whether or not they were included in a blood-saving protocol, and analysed between December 2012 and July 2013 (293 patients, prep group) and April 2015 to May 2016 (311 patients, posp group).

Microsatellite marker development from next-generation sequencing in the New England cottontail (Sylvilagus transitionalis) and cross-amplification in the eastern cottontail (S. floridanus).

Objective: The New England cottontail (Sylvilagus transitionalis) is a species of high conservation priority in the Northeastern United States, and was a candidate for federal listing under the Endangered Species Act until a recent decision determined that conservation actions were sufficient to preclude listing. The aim of this study was to develop a suite of microsatellite loci to guide future research efforts such as the analysis of population genetic structure, genetic variation, dispersal, and genetic mark-recapture population estimation.

Results: Thirty-five microsatellite markers containing tri- and tetranucleotide sequences were developed from shotgun genomic sequencing of tissue from S.

Renal Tuberculosis in a 9 Months Old: Case Report and Review of the Literature.

A nine months old girl with prenatal diagnosis of bilateral hydronephrosis underwent serious studies and in view of the presumed diagnosis of right functional annulment, a right laparoscopic nephroureterectomy was performed. The anatomopatological result was suggestive of tuberculosis without previous contact with the disease. Postoperatively, the child received antituberculosis therapy (ATT) for a full 8 months (isoniazid, rifampin, pyrazinamide and ethambutol for 2 months and isoniazid and rifampin for 6 months) and the follow-up tests revealed improvement of ureterohydronephrosis in left kidney.

Effects of lignocaine on pressor response to laryngoscopy and endotracheal intubation during general anaesthesia in rigid suspension laryngoscopy.

Objective: This study aimed to compare the effects of topical and systemic lignocaine on the circulatory response to direct laryngoscopy performed under general anaesthesia.

Methods: Ninety-nine patients over 20 years of age, with a physical status of I-II (classified according to the American Society of Anesthesiologists), were randomly allocated to 3 groups. One group received 5 ml of 0.

Thrombolysis and clinical outcome in patients with stroke after implementation of the Tyrol Stroke Pathway: a retrospective observational study.

Background: Intravenous thrombolysis for ischaemic stroke remains underused worldwide. We aimed to assess whether our statewide comprehensive stroke management programme would improve thrombolysis use and clinical outcome in patients.

Methods: In 2008-09, we designed the Tyrol Stroke Pathway, which provided information campaigns for the public and standardised the entire treatment pathway from stroke onset to outpatient rehabilitation.

Scattering by a boundary with complex structure.

The distribution of escape times is usually studied in open billiards theory. In this work, we will concentrate on another important question: The distribution of outgoing rays by exit directions, which we refer to as billiard's indicatrix. It can be obtained analytically and consists of two parts: the symmetric diffuse part and the asymmetric directed part.
