Factors associated with bicycle helmet use and proper fit: a cross-sectional survey of Montreal cyclists during the COVID-19 pandemic.

Objectives: With increased bicycle use during the COVID-19 pandemic and growing availability of bicycle-sharing programs in Montreal, we hypothesize helmet use has decreased. The aim of this study was to evaluate helmet use and proper fit among Montreal cyclists during the pandemic relative to historical data.

Methods: Nine observers collected data on bike type, gender, helmet use, and ethnicity using the iHelmet© app at 18 locations across the island of Montreal from June to September 2021.

COVID-19 detection and spread control: what initiatives in Italy for the homeless population?

In Italy COVID-19 pandemic had a severe impact. The homeless live in situations aggravating their poor health conditions and comorbidities. Although homeless people are a fragile category, no dedicated measures by public health departments seem to be applied infrequently to this population.

Cognitive Aids for the Management of Thoracic Anesthesia Emergencies: Consensus Guidelines on Behalf of a Canadian Thoracic Taskforce.

A cognitive aid is a tool used to help people accurately and efficiently perform actions. Similarly themed cognitive aids may be collated into a manual to provide relevant information for a specific context (eg, operating room emergencies). Expert content and design are paramount to facilitate the utility of a cognitive aid, especially during a crisis when accessible memory may be limited and distractions may impair task completion.

The first report on coronavirus disease 2019 (COVID-19) vaccine refusal by patients with solid cancer in Italy: Early data from a single-institute survey.

Introduction: Patients with cancer have an increased risk of complications from coronavirus disease 2019 (COVID-19) infection, including death, and thus, they were considered as high-priority subjects for COVID-19 vaccination. We report on the compliance with the COVID-19 vaccine of patients affected by solid tumours.

Materials And Methods: Patients with cancer afferent to Medical Oncology 1 Unit of Regina Elena National Cancer Institute in Rome were considered eligible for vaccination if they were receiving systemic immunosuppressive antitumor treatment or received it in the last 6 months or having an uncontrolled advanced disease.

Intermittent use of resuscitative endovascular balloon occlusion of the aorta in penetrating gunshot wound of the lower extremity.

The use of resuscitative endovascular balloon occlusion of the aorta (REBOA) in penetrating injuries is an emerging adjunct in the civilian trauma surgeon’s toolbox for the management of traumatic hemorrhagic shock. Furthermore, within the Canadian civilian context, little has been reported with regard to its use as an assisted damage-control measure in vascular reconstruction of the lower extremity. We report a case of penetrating gunshot injury of the lower extremity where the preoperative deployment of REBOA had a remarkable positive impact in the resuscitation phase and the intraoperative control of blood loss.

The Effect of Labor Epidural Analgesia on Breastfeeding Outcomes: A Prospective Observational Cohort Study in a Mixed-Parity Cohort.

Background: The effect of labor epidural analgesia (LEA) on successful breastfeeding has been evaluated in several studies with divergent results. We hypothesized that LEA would not influence breastfeeding status 6 weeks postpartum in women who intended to breastfeed in an environment that encourages breastfeeding.

Methods: In this prospective observational cohort study, a total of 1204 women intending to breastfeed, delivering vaginally with or without LEA, were included; breastfeeding was recorded at 3 days and 6 weeks postpartum.

Trauma Surveillance and Registry Development in Mozambique: Results of a 1-Year Study and the First Phase of National Implementation.

Background: Mozambique has had no policy-driven trauma system and no hospital-based trauma registries, and injury was not a public health priority. In other low-income countries, trauma system implementation and trauma registries have helped to reduce mortality from injury by up to 35%. In 2014, we introduced a trauma registry in four hospitals in Maputo serving 18,000 patients yearly.

Deployment of second-generation resuscitative endovascular balloon occlusion of the aorta for unresponsive hypotension in a polytrauma patient.

Noncompressible hemorrhagic control remains one of the most challenging areas in damage control medicine and continues to be a leading cause of preventable death. For decades, emergency thoracotomy or laparotomy and aortic cross clamping have remained the gold standard intervention. Recently, there has been a movement toward less invasive techniques for noncompressible hemorrhagic control, such as resuscitative endovascular balloon occlusion of the aorta (REBOA).

Additional and repeated computed tomography in interfacility trauma transfers: Room for standardization.

Background: Despite the recommendations of the Advanced Trauma Life Support course of the American College of Surgeons, patients undergo computed tomography (CT) in local hospitals before transfer to a trauma center. The problem of repeat CTs caused by technical and protocol issues is ongoing. The objective is to measure the importance of repeat CTs and CTs involving other body regions.

Multicenter evaluation of the cobas m 511 integrated hematology analyzer.

Introduction: The cobas m 511 integrated hematology analyzer conducts a complete blood count (CBC), white blood cell (WBC) differential, reticulocyte count, and nucleated red blood cell count using automated digital microscopy. This multicenter study validated the analytical performance of the cobas m 511 system.

Methods: Repeatability, reproducibility, carryover, mode-to-mode comparison, cytomorphology, WBC clinical sensitivity, and method comparison were analyzed at four clinical sites using residual whole blood clinical samples (n = 2546) and fresh whole blood from healthy volunteers (n = 480).

Development and validation of a new pediatric resuscitation and trauma outcome (PRESTO) model using the U.S. National Trauma Data Bank.

Background: There is a need for a pediatric trauma outcomes benchmarking model that is adapted for Low-and-Middle-Income Countries (LMICs). We used the National-Trauma-Data-Bank (NTDB) and applied constraints specific to resource-poor environments to develop and validate an LMIC-specific pediatric trauma score.

Methods: We selected a sample of pediatric trauma patients aged 0-14years in the NTDB from 2007 to 2012.

The Relationship Between Women's Intention to Request a Labor Epidural Analgesia, Actually Delivering With Labor Epidural Analgesia, and Postpartum Depression at 6 Weeks: A Prospective Observational Study.

Background: Postpartum depression (PPD) is associated with pain during and after delivery, with studies showing reduced rates among women delivering with labor epidural analgesia (LEA). We hypothesized that women who intend to deliver with LEA but do not receive it are at higher risk for PPD at 6 weeks due to the combined experience of untreated labor pain and unmatched expectations during labor, and evaluated the interaction between labor plans related to LEA, satisfaction with pain control when actually delivering with LEA, and PPD at 6 weeks after delivery.

Methods: A total of 1497 women with a vaginal delivery were enrolled into this prospective longitudinal study.

infections in an oncologic day ward: description of a cluster among high-risk patients.

Background: , an environmental microorganism, has been occasionally associated with healthcare infections. The aim of this study was to investigate an outbreak caused by in oncology patients.

Methods: Case definition: Oncology outpatients attending a day ward, with positive blood and/or central venous catheter (CVC) culture for spp from September 2013 - June 2014.

Association between ischemic heart disease and systemic lupus erythematosus-a large case-control study.

Ischemic heart disease (IHD) is a well identified cause of mortality in systemic lupus erythematosus (SLE) patients due to an accelerated premature atherosclerosis. We investigated the proportion of comorbid IHD among SLE patients derived from a large, national real-life database. Using data from the largest HMO in Israel, the Clalit Health Services, we selected for patients with SLE.

Risk Factors for Unintended Dural Puncture in Obstetric Patients: A Retrospective Cohort Study.

Background: Unintended dural puncture (UDP) is one of the main risks of epidural analgesia, with a reported incidence of approximately 1.5% among the obstetric population. UDP is associated with maternal adverse outcomes, with the most frequent adverse outcome being postdural puncture headache (PDPH).
