Abstract
BACKGROUND Virtual care in Canada rapidly expanded during the COVID-19 pandemic in a low-rules environment in response to pressing needs for ongoing access to care amid public health restrictions. Emergency medicine specialists now face the challenge of advising on which virtual urgent care services ought to remain as part of comprehensive emergency care. Consideration must be given to safe, quality, and appropriate care as well as issues of equitable access, public demand, and sustainability (financial and otherwise). The aim of this project was to summarize current literature and expert opinion and formulate recommendations on the path forward for virtual care in emergency medicine. METHODS We formed a working group of emergency medicine physicians from across Canada working in a variety of practice settings. The virtual care working group conducted a scoping review of the literature and met monthly to discuss themes and develop recommendations. The final recommendations were circulated to stakeholders for input and subsequently presented at the 2023 Canadian Association of Emergency Physicians (CAEP) Academic Symposium for discussion, feedback, and refinement. RESULTS The working group developed and reached unanimity on nine recommendations addressing the themes of system design, equity and accessibility, quality and patient safety, education and curriculum, financial models, and sustainability of virtual urgent care services in Canada. CONCLUSION Virtual urgent care has become an established service in the Canadian health care system. Emergency medicine specialists are uniquely suited to provide leadership and guidance on the optimal delivery of these services to enhance and complement emergency care in Canada.

Evolution of body mass index and complications rate in severely or morbidly obese patients undergoing total knee arthroplasty. Orthop Traumatol Surg Res 2023; 109:103704. [PMID: 37832867 DOI: 10.1016/j.otsr.2023.103704] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 06/26/2023] [Accepted: 07/05/2023] [Indexed: 10/15/2023]
Abstract
INTRODUCTION Associations between obesity and knee osteoarthritis or complications after total knee arthroplasty (TKA) are well established. The procedure can significantly improve knee function, favoring weight loss, despite the risk of surgical complications. The main objective of the present study was to assess change in body mass index (BMI) after TKA in patients with severe or morbid obesity (BMI≥35kg/m2). The secondary endpoint was the rate of surgical revision. The hypotheses were that there is no significant change in BMI after TKA and that there is a significant rate of revision. METHODS This retrospective descriptive study was conducted for the period June 2009 to December 2019. Thirty-three patients (48 knees) were included: 27 women, 6 men; mean age, 66.5 years (range, 55-80). Preoperatively, 11 patients had BMI 35-39.9kg/m2 and 22 BMI≥40 (including 11 with BMI≥45kg/m2). The preoperative axis was in varus for 35 patients (73%, including 54%≥10°) and in valgus for 13 (27% including 33%≥10°). Radiological and clinical evaluation was carried out at 3 months and 1 year postoperatively. At≥2 years, change in BMI and EQ5D functional score were established by telephone survey; >5% change in BMI was considered significant. RESULTS Mean follow-up was 6.9±2.3 years (range, 2.9-10.5). Twenty-five patients (38 knees) were included for analysis. Mean postoperative BMI was 41±5kg/m2, with a mean decrease of 1.2±3.6kg/m2. At the last follow-up, BMI had increased in 8 patients (32%), including 3 by >5% (12%), and decreased in 16 (64%), including 7 by >5% (28%). The higher the baseline BMI, the greater the decrease: for BMI [35-39.9], -0.81 (range, -6.8; +4.3); for BMI [40-44.5],-1 (range, -9; +5.22); and for BMI>45, -1.54 (range, -3.97; +1.3). EQ5D averaged 0.75 at last follow-up. The higher the preoperative BMI, the more satisfactory the postoperative EQ5D: EQ5D for BMI [35-39.9]=0.71 (range, 0.36; 1); for BMI [40-44.5]=0.75 (range, 0.45; 1); and for BMI>45=0.80 (range, 0.48; 1). Four early surgical site infections (10.5%) and 2 isolated changes of the tibial component for early loosening (5.2%) required surgical revision. CONCLUSION Patients with severe or morbid obesity had a low tendency to lose weight after TKA, but this does not appear to us to be clinically relevant: the functional results were good. Nevertheless, this series showed a significant rate of revision (15%). TKA was feasible in patients with BMI≥35kg/m2, but requires appropriate patient information. LEVEL OF EVIDENCE IV.

Surgical technique of anterior cruciate ligament ligamentoplasty with pedicular hamstrings via an inside-out approach: BIOFAST hamstring tendons graft. Orthop Traumatol Surg Res 2022; 108:103192. [PMID: 34952217 DOI: 10.1016/j.otsr.2021.103192] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 06/06/2021] [Accepted: 06/21/2021] [Indexed: 02/03/2023]
Abstract
This surgical technique of anterior cruciate ligament (ACL) reconstruction uses a 4-stranded hamstring tendons graft (HG), via an inside-out approach with a femoral cortical button and a tibial screw. It offers preservation of the tibial attachment of the hamstrings and enables double tibial fixation: biological and mechanical. This technique, "BIOFAST HG", does not require any calculation of the length of the tunnels, nor the use of different sized, or adjustable, buttons. If the sliding in the femoral tunnel fails, it is possible to easily convert to a so-called "classic technique". The first 60 cases were reviewed with a conversion rate of 3%. This technique allows the benefits of a pedicled graft over the classic HG technique in a simple way, with minimal conversions to the classic technique.

Abstract
INTRODUCTION Corona-virus Disease 2019 (COVID-19) has had a huge impact on the delivery of healthcare worldwide, particularly elective surgery. There is a lack of data regarding risk of postoperative COVID-19 infection in children undergoing elective surgery, and regarding the utility of pre-operative COVID-19 testing, and preoperative "cocooning" or restriction of movements. The purpose of this present study was to examine the safety of elective paediatric Otolaryngology surgery during the COVID-19 pandemic with respect to incidence of postoperative symptomatic COVID-19 infection or major respiratory complications. MATERIALS AND METHODS Prospective cohort study of paediatric patients undergoing elective Otolaryngology surgery between September and December 2020. Primary outcome measure was incidence of symptomatic COVID-19 or major respiratory complications within the 14 days after surgery. Parents of prospectively enrolled patients were contacted 14 days after surgery and enquiry made regarding development of postoperative symptoms, COVID-19 testing, or diagnosis of COVID-19. RESULTS 302 patients were recruited. 125 (41.4%) underwent preoperative COVID-19 RT-PCR testing. 66 (21.8%) restricted movements prior to surgery. The peak 14-day COVID-19 incidence during the study was 302.9 cases per 100,000 population. No COVID-19 infections or major respiratory complications were reported in the 14 day follow-up period. CONCLUSION The results of our study support the safety of elective paediatric Otolaryngology surgery during the pandemic, in the setting of community incidence not exceeding that observed during the study period.

Abstract
Real-time polymerase chain reaction (RT-PCR) is used to rule out SARS-CoV-2 prior to surgery, however few studies have evaluated patients with negative testing after surgery. Some 499 patients with negative tests were followed for 14 days after surgery, 39 were retested but none developed positive RT-PCR after operation. The risk of developing a positive RT-PCR after surgery was 0.74 per cent.

Abstract
Objectives: To compare post-concussion symptoms (PCS) and return to normal activities between mild Traumatic Brain Injury (mTBI) patients with or without concomitant injuries at 7-and 90 days post-mTBI.Methods: Design: Sub-analysis of a multicentre prospective cohort study. PARTICIPANTS AND SETTING patients with mTBI from 7 Canadian Emergency Departments. PROCEDURE Research assistants conducted telephone follow-ups using the Rivermead Postconcussion Symptoms Questionnaire (RPQ) at 7-, 30- and 90 days post-mTBI. MAIN OUTCOME Presence of PCS (RPQ: ≥3 symptoms) at 90 days. SECONDARY OUTCOMES RPQ score ≥21, prevalence of individual RPQ symptoms and patients' return to normal activities, at 7- and 90-days. Adjusted risk ratios (RR) were calculated.Results: 1725 mTBI patients were included and 1055 (61.1%) had concomitant injuries. Patients with concomitant injuries were at higher risk of having ≥3 symptoms on the RPQ (RR:1.26 [95% CI 1.01-1.58]) at 90 days. They were also at higher risk of experiencing specific symptoms (dizziness, fatigue, headaches and taking longer to think) and of non-return to their normal activities (RR:2.11 [95% CI 1.30-3.45]).Conclusion: Patients with concomitant injuries have slightly more PCS and seemed to be at higher risk of non-return to their normal activities 90 days, compared to patients without concomitant injuries.

Abstract
Importance Identification of geographic population-based differences in genotype and phenotype heterogeneity are important for targeted and patient-specific diagnosis and treatment, counseling, and screening strategies. Objective To report disease-causing variants and their detailed phenotype in patients with bilateral congenital cataract from a single center in Switzerland and thereby draw a genetic map and perform a genotype-phenotype comparison of this cohort. Design, Setting, and Participants This clinical and molecular-genetic cohort study took place through the collaboration of the Department of Ophthalmology at the University Hospital Zurich and the Institute of Medical Molecular Genetics, University of Zurich, Schlieren, Switzerland. Thirty-seven patients from 25 families with different types of bilateral congenital cataract were included. All participating family members received a comprehensive eye examination. Whole exome sequencing was performed in the index patients, followed by a filtering process to detect possible disease-associated variants in genes previously described in association with congenital cataract. Probable disease-causing variants were confirmed by Sanger sequencing in available family members. All data were collected from January 2018 to June 2020, and the molecular-genetic analyses were performed from January 2019 to July 2020. Main Outcomes and Measures Identification of the underlying genetic causes of bilateral congenital cataract, including novel disease-causing variants and phenotype correlation. Results Among the 37 patients (18 [49%] male and 19 [51%] female; mean [SD] age, 17.3 [15.9] years) from 25 families, pathogenic variants were detected in 20 families (80% detection rate), which included 13 novel variants in the following genes: BCOR, COL4A1, CRYBA2, CRYBB2, CRYGC, CRYGS, GJA3, MAF, NHS, and WFS1. Putative disease-causing variants were identified in 14 of 20 families (70%) as isolated cases and in 6 of 20 families (30%) with syndromic cases. A recessive variant in the CRYBB2 gene in a consanguineous family with 2 affected siblings showing a nuclear and sutural cataract was reported in contrast to previously published reports. In addition, the effect on splicing in a minigene assay of a novel splice site variant in the NHS gene (c.[719-2A>G]) supported the pathogenicity of this variant. Conclusions and Relevance This study emphasizes the importance of genetic testing of congenital cataracts. Known dominant genes need to be considered for recessive inheritance patterns. Syndromic types of cataract may be underdiagnosed in patients with mild systemic features.

Abstract
PURPOSE To (i) describe a series of patients with isolated or syndromic nanophthalmos with the underlying genetic causes, including novel pathogenic variants and their functional characterization and (ii) to study the association of retinal dystrophy in patients with MFRP variants, based on a detailed literature review of genotype-phenotype correlations. METHODS Patients with nanophthalmos and available family members received a comprehensive ophthalmological examination. Genetic analysis was based on whole-exome sequencing and variant calling in core genes including MFRP, BEST1, TMEM98, PRSS56, CRB1, GJA1, C1QTNF5, MYRF and FAM111A. A minigene assay was performed for functional characterization of a splice site variant. RESULTS Seven patients, aged between three and 65 years, from five unrelated families were included. Novel pathogenic variants in MFRP (c.497C>T, c.899-3C>A, c.1180G>A), and PRSS56 (c.1202C>A), and a recurrent de novo variant in FAM111A (c.1706G>A) in a patient with Kenny-Caffey syndrome type 2, were identified. In addition, we report co-inheritance of MFRP-related nanophthalmos and ADAR-related Aicardi-Goutières syndrome. CONCLUSION Nanophthalmos is a genetically heterogeneous condition, and the severity of ocular manifestations appears not to correlate with variants in a specific gene. However, retinal dystrophy is only observed in patients harbouring pathogenic MFRP variants. Furthermore, heterozygous carriers of MFRP and PRSS56 should be screened for the presence of high hyperopia. Identifying nanophthalmos as an isolated condition or as part of a syndrome has implications for counselling and can accelerate the interdisciplinary care of patients.

Abstract
Coloboma and microphthalmia (C/M) are related congenital eye malformations, which can cause significant visual impairment. Molecular diagnosis is challenging as the genes associated to date with C/M account for only a small percentage of cases. Overall, the genetic cause remains unknown in up to 80% of patients. High throughput DNA sequencing technologies, including whole-exome sequencing (WES), are therefore a useful and efficient tool for genetic screening and identification of new mutations and novel genes in C/M. In this study, we analyzed the DNA of 19 patients with C/M from 15 unrelated families using singleton WES and data analysis for 307 genes of interest. We identified seven novel and one recurrent potentially disease-causing variants in CRIM1, CHD7, FAT1, PTCH1, PUF60, BRPF1, and TGFB2 in 47% of our families, three of which occurred de novo. The detection rate in patients with ocular and extraocular manifestations (67%) was higher than in patients with an isolated ocular phenotype (46%). Our study highlights the significant genetic heterogeneity in C/M cohorts and emphasizes the diagnostic power of WES for the screening of patients and families with C/M.

Abstract
Purpose The aim of this study was to investigate the molecular basis of childhood glaucoma in Switzerland to recommend future targeted genetic analysis in the Swiss population. Methods Whole-exome sequencing and copy number variation (CNV) analysis was performed in a Swiss cohort of 18 patients from 14 unrelated families. Identified variants were validated by Sanger sequencing and multiplex ligation-dependent probe amplification. Breakpoints of structural variants were determined by a microarray. A minigene assay was conducted for functional analysis of a splice site variant. Results A diagnosis of primary congenital glaucoma was made in 14 patients, of which six (43%) harbored pathogenic variants in CYP1B1, one (7%) a frameshift variant in FOXC1, and seven (50%) remained without a genetic diagnosis. Three patients were diagnosed with glaucoma associated with nonacquired ocular anomalies, of which two patients with mild ocular features of Axenfeld-Rieger syndrome harbored a FOXC1 duplication plus an additional FOXC1 missense variant, and one patient with a Barkan membrane remained without genetic diagnosis. A diagnosis of juvenile open-angle glaucoma was made in one patient, and genetic analysis revealed a FOXC1 duplication. Conclusions Sequencing of CYP1B1 and FOXC1, as well as analysis of CNVs in FOXC1, should be performed before extended gene panel sequencing. Translational Relevance The identification of the molecular cause of childhood glaucoma is a prerequisite for genetic counseling and personalized care for patients and families.

Abstract
Background
Lack of access to gastroenterologists may influence outcomes for upper gastrointestinal bleeding (UGIB).
Aims
To evaluate admission and re-admissions for patients with UGIB across the five health zones in Alberta that vary by access to local gastroenterologists.
Methods
Administrative databases identified all patients presenting to an emergency department with an UGIB who were admitted to hospital in Alberta from 2010 to 2015 (n = 17143). Admissions were stratified based the patients’ residence: Calgary, Edmonton, South, Central and North. Log-linear regression assessed an Average Annual Percentage Change (AAPC) in the incidence of UGIB hospitalizations with associated 95% confidence intervals (CI). Endoscopy and readmission to hospital within 30 days of discharge was evaluated.
Results
The per capita number of gastroenterologists was highest in Calgary (3.9 per 100,000) and Edmonton (3.8) as compared to Central (0.84), South (0.66), and North (0.41). Incidence of hospital admission for UGIB decreased in Alberta (AAPC=-6.9%; 95%CI: -8.4,-5.4); though rates for UGIB in Calgary and Edmonton was less common than non-metropolitan zones (Figure 1). Patients living in Calgary and Edmonton had lower 30-day hospital readmission rate (4.30% and 4.84%) as compared to North (11.95%), Central (10.74%), and South (8.24%) (Table 1). Patients in Calgary and Edmonton underwent endoscopic evaluation more frequently (79.6% and 76.1%) than the North, Central, and South (68.41%, 66.3%, and 71.36%).
Conclusions
Patients presenting to emergency departments with UGIB were more likely to be admitted to hospital and subsequently be re-admitted within 30-days of discharge in regions underrepresented by gastroenterologists. Improving access to local gastroenterologists in may reduce the burden of hospitalizations for an UGIB.

Abstract
Introduction Drain usage is commonplace in head and neck surgery. There is an increasing body of literature disputing their routine placement in certain procedures. The aim of this study is to explore modern-day practice in terms of drain usage and the use of haemostatic agents. Methods A simple questionnaire was devised and sent to 35 ENT Surgeons across 10 units nationally. Results There was an overall response rate of 77.1% (n=27). There was considerable heterogeneity amongst surgeons in terms of indication for insertion, how the decision is made to remove the drain and if any alternative/adjunctive haemostatic agents are being used. Discussion The management of drains is poorly defined and guidelines are lacking. With increased pressure on resources, the risk of infection and discomfort to the patient, further reflection is required to evaluate if careful patient selection rather than habitual drain insertion in every case is more appropriate.

Abstract
The 2018 update of the Canadian Stroke Best Practice Recommendations for Acute Stroke Management, 6th edition, is a comprehensive summary of current evidence-based recommendations, appropriate for use by healthcare providers and system planners caring for persons with very recent symptoms of acute stroke or transient ischemic attack. The recommendations are intended for use by a interdisciplinary team of clinicians across a wide range of settings and highlight key elements involved in prehospital and Emergency Department care, acute treatments for ischemic stroke, and acute inpatient care. The most notable changes included in this 6th edition are the renaming of the module and its integration of the formerly separate modules on prehospital and emergency care and acute inpatient stroke care. The new module, Acute Stroke Management: Prehospital, Emergency Department, and Acute Inpatient Stroke Care is now a single, comprehensive module addressing the most important aspects of acute stroke care delivery. Other notable changes include the removal of two sections related to the emergency management of intracerebral hemorrhage and subarachnoid hemorrhage. These topics are covered in a new, dedicated module, to be released later this year. The most significant recommendation updates are for neuroimaging; the extension of the time window for endovascular thrombectomy treatment out to 24 h; considerations for treating a highly selected group of people with stroke of unknown time of onset; and recommendations for dual antiplatelet therapy for a limited duration after acute minor ischemic stroke and transient ischemic attack. This module also emphasizes the need for increased public and healthcare provider’s recognition of the signs of stroke and immediate actions to take; the important expanding role of paramedics and all emergency medical services personnel; arriving at a stroke-enabled Emergency Department without delay; and launching local healthcare institution code stroke protocols. Revisions have also been made to the recommendations for the triage and assessment of risk of recurrent stroke after transient ischemic attack/minor stroke and suggested urgency levels for investigations and initiation of management strategies. The goal of this updated guideline is to optimize stroke care across Canada, by reducing practice variations and reducing the gap between current knowledge and clinical practice.

IRF4 and BATF are critical for CD8⁺ T-cell function following infection with LCMV. Cell Death Differ 2014; 21:1050-60.

Abstract
CD8(+) T-cell functions are critical for preventing chronic viral infections by eliminating infected cells. For healthy immune responses, beneficial destruction of infected cells must be balanced against immunopathology resulting from collateral damage to tissues. These processes are regulated by factors controlling CD8(+) T-cell function, which are still incompletely understood. Here, we show that the interferon regulatory factor 4 (IRF4) and its cooperating binding partner B-cell-activating transcription factor (BATF) are necessary for sustained CD8(+) T-cell effector function. Although Irf4(-/-) CD8(+) T cells were initially capable of proliferation, IRF4 deficiency resulted in limited CD8(+) T-cell responses after infection with the lymphocytic choriomeningitis virus. Consequently, Irf4(-/-) mice established chronic infections, but were protected from fatal immunopathology. Absence of BATF also resulted in reduced CD8(+) T-cell function, limited immunopathology, and promotion of viral persistence. These data identify the transcription factors IRF4 and BATF as major regulators of antiviral cytotoxic T-cell immunity.

Abstract
Cluster of differentiation (CD)8(+) T cells are like a double edged sword during chronic viral infections because they not only promote virus elimination but also induce virus-mediated immunopathology. Elevated levels of reactive oxygen species (ROS) have been reported during virus infections. However, the role of ROS in T-cell-mediated immunopathology remains unclear. Here we used the murine lymphocytic choriomeningitis virus to explore the role of ROS during the processes of virus elimination and induction of immunopathology. We found that virus infection led to elevated levels of ROS producing granulocytes and macrophages in virus-infected liver and spleen tissues that were triggered by the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase. Lack of the regulatory subunit p47phox of the NADPH oxidase diminished ROS production in these cells. While CD8(+) T cells exhibited ROS production that was independent of NADPH oxidase expression, survival and T-cell function was elevated in p47phox-deficient (Ncf1(-/-)) mice. In the absence of p47phox, enhanced T-cell immunity promoted virus elimination and blunted corresponding immunopathology. In conclusion, we find that NADPH-mediated production of ROS critically impairs the immune response, impacting elimination of virus and outcome of liver cell damage.

Abstract
The structural elucidation of 2α-cyclodextrin/1-octanethiol, 2α-cyclodextrin/1-octylamine and 2α-cyclodextrin/1-nonanoic acid inclusion complexes by nuclear magnetic resonance (NMR) spectroscopy and molecular modeling has been achieved. The detailed spatial configurations are proposed for the three inclusion complexes based on 2D NMR method. ROESY experiments confirm the inclusion of guest molecules inside the α-cyclodextrin (α-CD) cavity. On the other hand, the host-guest ratio observed was 2:1 for three complexes. The detailed spatial configuration proposed based on 2D NMR methods were further interpreted using molecular modeling studies. The theoretical calculations are in good agreement with the experimental data.

Abstract
The relationships between five potential indicators of alcohol-related harm following drinking on licensed premises in Perth were explored. These were annual purchases made by individual licensees of 'high' (>=3.8%) and 'low' (<3.8%) alcohol content drinks, the number of times a particular licensed establishment is cited by drivers as the last place of drinking prior to failing a roadside breath-test (including after accidents) and the annual number of assaults occurring either on or in the vicinity of particular licensed premises. The study area selected was a central part of the Perth metropolitan area with 367 licensed premises serving a residential population of 400 000. Highly significant correlations were found between each of the five variables. The correlations involving purchases of low alcohol drinks, however, were small. When purchases of alcohol were controlled, significant, though lower, correlations, were still evident between the other three variables. This suggests that there are risk factors other than extent of alcohol sales which further research will need to identify, and that these indicators of harm can be of value in monitoring the impact of future intervention strategies.

Abstract
Summary
Objectives:
Tissue microarray (TMA) techniques are among the most promising developments in biomedicine during the last decade. Bioinformatics techniques are indispensable for storing and processing the masses of data related with tissue archive administration and investigation of raw data. Interrelationship between experimental and computational work will be shown.
Methods:
Tissue specimen arrays allow parallel analysis of huge amounts of samples. TMA techniques thus produce enormous masses of raw data, and optimal use of data can only be made using modern bioinformatics techniques based on huge storage systems, scalable multilayer software architecture and high-throughput algorithms for retrieval and statistical processing. Further crucial issues addressed by informatics techniques are specimen identification during the whole processing chain, and anonymization whenever scientific work is performed without regard to a certain patient.
Results:
TMA supported by bioinformatics methods has helped in identification of biomarkers, mainly in cancer diagnosis. Moreover, it provides powerful means of quality assurance and training in histopathology.
Conclusions:
Further statistical analyses seem to be necessary to detect if certain biomarkers are present in nearly all kinds of specimen of the concerned patient, which would allow effective mass screening based on easily accessible specimen. Some investigations showed low dependence on the specimen localization, whereas others suggest to be extremely careful in material selection for the recipient block.
