Epidemiology of Pediatric Tumors in Quebec: A 17-Year Report of Cancer in Young People in the Canada Registry.

Background: Cancer is the leading cause of disease-related death among children of more than 1 year of age. However, childhood cancer risk factors and etiology are yet to be fully understood. The goal of this study is to identify geographic variation among children and adolescents diagnosed with pediatric tumors between 2001 and 2018 in the province of Quebec.

Value-based comparison of ambulatory children with respiratory diseases in an emergency department and a walk-in clinic: a retrospective cohort study in Québec, Canada.

Objective: To compare health outcomes and costs given in the emergency department (ED) and walk-in clinics for ambulatory children presenting with acute respiratory diseases.

Design: A retrospective cohort study.

Setting: This study was conducted from April 2016 to March 2017 in one ED and one walk-in clinic.

Development of a Patient-Reported Experience Measure Tool for Ambulatory Patients With Acute Unexpected Needs: The APEX Questionnaire.

The aim of this study was to develop a patient-reported experience measure (PREM) for comparing the experience of care received by ambulatory patients with acute unexpected needs presenting in emergency departments (EDs), walk-in clinics, and primary care practices. The Ambulatory Patient EXperience (APEX) questionnaire was developed using a 5-phase mixed-methods approach. The questionnaire was pretested by asking potential users to rate its clarity, usefulness, redundancy, content and face validities, and discrimination on a 9-point scale (1 = strongly disagree to 9 = strongly agree).

Cancer anorexia-cachexia syndrome is characterized by more than one inflammatory pathway.

Background: The interdependence of cytokines and appetite-modifying hormones implicated in cancer anorexia-cachexia syndrome (CACS) remains unclear. This study aimed to regroup these cytokines and hormones into distinct inflammatory (or non-inflammatory) pathways and determine whether these pathways can classify patients with CACS phenotypes.

Methods: Clinical characteristics of 133 patients [61.

Untargeted metabolomics identifies metabolic dysregulation of sphingolipids associated with aggressive chronic lymphocytic leukaemia and poor survival.

Background: Metabolic dependencies of chronic lymphocytic leukaemia (CLL) cells may represent new personalized treatment approaches in patients harbouring unfavourable features.

Methods: Here, we used untargeted metabolomics and lipidomics analyses to isolate metabolomic features associated with aggressive CLL and poor survival outcomes. We initially focused on profiles associated with overexpression of the adverse metabolic marker glycosyltransferase (UGT2B17) associated with poor survival and drug resistance.

Parents' perspective on pediatric emergency department visits for low-acuity conditions before and during the COVID-19 pandemic: a cross-sectional bicentric study.

Objectives: The primary objective of this study was to describe and compare the motivation of parents/guardians to bring children with low-acuity conditions to a tertiary-care pediatric emergency department (ED) versus a clinic before and after the pandemic. The secondary objectives were to describe and compare the demographic and clinical characteristics of the population studied and the impact of the pandemic on their access to primary care services.

Methods: This is a cross-sectional study based on a survey administered to parents/guardians of patients presenting with low-acuity conditions at one of two EDs.

Docosahexaenoic acid-rich algae oil supplementation in mothers of preterm infants is associated with a modification in breast milk oxylipins profile.

Oxylipins are derived from enzymatic and non-enzymatic oxidation of n-3 and n-6 long-chain polyunsaturated fatty acids. They are known to be involved in inflammatory processes. The aim of this study was to describe the breast milk oxylipin profile following a docosahexaenoic acid (DHA) supplementation of mothers of preterm infants.

High infiltration of CD209 dendritic cells and CD163 macrophages in the peritumor area of prostate cancer is predictive of late adverse outcomes.

Introduction: Prostate cancer (PCa) shows considerable variation in clinical outcomes between individuals with similar diseases. The initial host-tumor interaction as assessed by detailed analysis of tumor infiltrating immune cells within the primary tumor may dictate tumor evolution and late clinical outcomes. In this study, we assessed the association between clinical outcomes and dendritic cell (DC) or macrophage (MΦ) tumor infiltration as well as with expression of genes related to their functions.

[Treatment tactics for patients with retention cysts, odontogenic cysts, mucocele and other pathologies of the maxillary sinuses as preparation for a sinus lift].

Objective: The aim the studi. Differential diagnosis of retention cysts of the maxillary sinus with odontogenic cysts, acute and chronic sinusitis, aspergillosis, and mucocele in preparation for sinus-lifting surgery.

Material And Methods: The analysis of the case histories of 265 patients aged 18-65 years of both sexes who were treated at the dental clinic «Rudenta Family» from 2016 to 2021 was carried out.

Circulating adrenal 11-oxygenated androgens are associated with clinical outcome in endometrial cancer.

Context: Recent evidence support that androgens play an important role in the etiology of endometrial cancer (EC). Adrenal-derived 11-oxygenated androgens are highly potent agonists of the androgen receptor (AR), comparable to testosterone (T) and dihydrotestosterone (DHT) that have not been studied in the context of EC.

Methodology: We studied a cohort of 272 newly diagnosed postmenopausal EC cases undergoing surgical treatment.

Does Growth Velocity Affect Associations between Birth Weight and Neurodevelopment for Infants Born Very Preterm?

Objective: To determine how neonatal growth velocity affects the association between birth weight and neurodevelopmental outcomes in infants born preterm.

Study Design: This study is a secondary analysis of the Maternal Omega-3 Supplementation to Reduce Bronchopulmonary Dysplasia in Very Preterm Infants (MOBYDIck) randomized multicenter trial conducted in breastfed infants born at <29 weeks of gestation, whose mothers were supplemented with docosahexaenoic acid or placebo during the neonatal period. Neurodevelopmental outcomes were assessed at 18-22 months of corrected age using the Bayley-III cognitive and language composite scores.

A value-based comparison of the management of respiratory diseases in walk-in clinics and emergency departments.

Objectives: Our aim was to compare some of the health outcomes and costs associated with value of care in emergency departments (ED) and walk-in clinics for ambulatory patients presenting with an acute respiratory disease.

Methods: A health records review was conducted from April 2016 through March 2017 in one ED and one walk-in clinic. Inclusion criteria were: (i) ambulatory patients at least 18 years old, (ii) discharged home with a diagnosis of upper respiratory tract infection (URTI), pneumonia, acute asthma, or acute exacerbation of chronic obstructive pulmonary disease.

Molecular test of Paget's disease of bone in families not linked to gene mutations.

Purpose: Paget's disease of bone (PDB) is a focal metabolic bone disorder characterized by an increased bone remodeling. Fifteen to 40 % of PDB patients have a familial form with an autosomal dominant inheritance. Disease-causing mutations of the gene have been linked to PDB in about 40 % of families whereas genes linked to the remaining families are unknown.

Circulating estradiol and its biologically active metabolites in endometriosis and in relation to pain symptoms.

Objectives: Endometriosis (EM) is an estrogen-dominant inflammatory disease linked to infertility that affects women of reproductive age. EM lesions respond to hormonal signals that regulate uterine tissue growth and trigger inflammation and pain. The objective of this study was to evaluate whether estradiol (E) and its biologically active metabolites are differentially associated with EM given their estrogenic and non-estrogenic actions including proliferative and inflammatory properties.

UGT2B28 accelerates prostate cancer progression through stabilization of the endocytic adaptor protein HIP1 regulating AR and EGFR pathways.

The androgen inactivating UGT2B28 pathway emerges as a predictor of progression in prostate cancer (PCa). However, the clinical significance of UGT2B28 tumoral expression and its contribution to PCa progression remain unclear. Using the Canadian Prostate Cancer Biomarker Network biobank (CPCBN; n = 1512), we analyzed UGT2B28 tumor expression in relation to clinical outcomes in men with localized PCa.

Analysis of sex-based differences to Bacillus Calmette-Guérin for non-muscle invasive bladder cancer.

Objective: To evaluate whether differences exist between men and women in response to intravesical BCG treatments. The incidence of urothelial carcinoma of the bladder is lower in women but they tend to present with more aggressive and advanced disease. Some prior studies also suggest there are sex-based differences in response to treatment for non-muscle invasive bladder tumors.

Adaptation of time-driven activity-based costing to the evaluation of the efficiency of ambulatory care provided in the emergency department.

Objectives: The aim of this study was: (1) to adapt the time-driven activity-based costing (TDABC) method to emergency department (ED) ambulatory care; (2) to estimate the cost of care associated with frequently encountered ambulatory conditions; and (3) to compare costs calculated using estimated time and objectively measured time.

Methods: TDABC was applied to a retrospective cohort of patients with upper respiratory tract infections, urinary tract infections, unspecified abdominal pain, lower back pain and limb lacerations who visited an ED in Québec City (Canada) during fiscal year 2015-2016. The calculated cost of care was the product of the time required to complete each care procedure and the cost per minute of each human resource or equipment involved.
