Introduction: This study sought to determine the rupture risk of asymptomatic abdominal aortic aneurysms (AAAs) undergoing interventions as a function of time to establish a maximal acceptable surgical delay.

Methods: A literature review was performed from inception to August 30, 2021, to assess the risk of rupture of aneurysms over time. The analysis was limited to men with asymptomatic AAAs.

The Use of Kidneys With Lower Longevity From Deceased Donors to Improve Access to Preemptive Renal Transplantation for Elderly Patients: A Qualitative Study.

Background: There is a gap between the number of patients waiting for a transplant and the number of kidneys available. Some deceased donor kidneys are currently nonutilized, as medical teams fear that they will experience suboptimal graft survival. However, these organs could provide an acceptable therapeutic option if they were allocated for preemptive kidney transplantation in elderly candidates.

Erector spinae plane block did not improve postoperative pain-related outcomes and recovery after video-assisted thoracoscopic surgery : a randomised controlled double-blinded multi-center trial.

Introduction: There is a sizable niche for a minimally invasive analgesic technique that could facilitate ambulatory video-assisted thoracoscopic surgery (VATS). Our study aimed to determine the analgesic potential of a single-shot erector spinae plane (ESP) block for VATS. The primary objective was the total hydromorphone consumption with patient-controlled analgesia (PCA) 24 h after surgery.

Patient Learning Pathway: Identifying Patient Competencies in Teledermatology for Effective Management of Dermatological Conditions.

Background: Dermatology consultations in Québec, Canada, face accessibility challenges, with most dermatologists concentrated in urban areas. Teledermatology, offering remote diagnosis and treatment, holds promise in overcoming these limitations. However, concerns regarding patient-doctor relationships and logistical issues exist.

[Mentalization of conflicts in group therapy: Destructivity and survival in the benefit of cohesion].

The high prevalence of personality disorders, along with their substantial functional impact, are important societal issues, which must be addressed by mental health services. Many treatments have shown significant benefits and have contributed to alleviate the difficulties tied to these disorders. Mentalization-based therapy (MBT), which is constituted of a group therapy modality, is an evidence-based treatment of borderline personality disorder.

Use of Invasive Brain-Computer Interfaces in Pediatric Neurosurgery: Technical and Ethical Considerations.

Invasive brain-computer interfaces hold promise to alleviate disabilities in individuals with neurologic injury, with fully implantable brain-computer interface systems expected to reach the clinic in the upcoming decade. Children with severe neurologic disabilities, like quadriplegic cerebral palsy or cervical spine trauma, could benefit from this technology. However, they have been excluded from clinical trials of intracortical brain-computer interface to date.

Lived Experiences of Hemodialysis Health Care Workers during the COVID-19 Pandemic: A Qualitative Study from the Quebec Renal Network.

Key Points: Hemodialysis workers' well-being and work were affected by the COVID-19 pandemics. Effective communication strategies and taking into account psychological distress are ways to mitigate the challenges faced by health care workers.

Background: The COVID-19 pandemic has disrupted health systems and created numerous challenges in hospitals worldwide for patients and health care workers (HCWs).

Lived Experiences of Patients Receiving Hemodialysis during the COVID-19 Pandemic: A Qualitative Study from the Quebec Renal Network.

Background: Hemodialysis patients have faced unique challenges during the COVID-19 pandemic. They face high risk of death if infected and have unavoidable exposure to others when they come to hospital three times weekly for their life-saving treatments. The objective of this study was to gain a better understanding of the scope and magnitude of the effects of the pandemic on the lived experience of patients receiving in-center hemodialysis.

A scoping review of malnutrition in patients undergoing interventions for peripheral arterial disease.

Background: Peripheral arterial disease (PAD) is associated with comorbid conditions and frailty. The role of preoperative nutrition in patients with PAD has not been well characterized. In the present scoping review, we sought to describe the prevalence and prognostic implications of preoperative malnutrition in patients undergoing vascular interventions for claudication or chronic limb-threatening ischemia (CLTI).

Characteristics and outcomes of patients with COVID-19 admitted to hospital and intensive care in the first phase of the pandemic in Canada: a national cohort study.

Background: Clinical data on patients admitted to hospital with coronavirus disease 2019 (COVID-19) provide clinicians and public health officials with information to guide practice and policy. The aims of this study were to describe patients with COVID-19 admitted to hospital and intensive care, and to investigate predictors of outcome to characterize severe acute respiratory infection.

Methods: This observational cohort study used Canadian data from 32 selected hospitals included in a global multisite cohort between Jan.

Age-Related Increases in Marrow Fat Volumes have Regional Impacts on Bone Cell Numbers and Structure.

The increasing levels of bone marrow fat evident in aging and osteoporosis are associated with low bone mass and attributed to reduced osteoblastogenesis. Local lipotoxicity has been proposed as the primary mechanism driving this reduction in bone formation. However, no studies have examined the correlation between high levels of marrow fat volumes and changes in local cellularity.

Differential Effects of Long-Term Caloric Restriction and Dietary Protein Source on Bone and Marrow Fat of the Aging Rat.

Long-term caloric restriction (CR) has been shown to be beneficial to various tissues and organs. In contrast, CR exerts differential effects on bone, which could be due in part to the nature of the protein regime utilized. Male Sprague Dawley rats (8-month-old) were subjected for 12 months to 40% CR in macronutrients and compared with rats fed ad libitum for the same period.

c-Myc is a regulator of the PKD1 gene and PC1-induced pathogenesis.

Autosomal dominant polycystic kidney disease (ADPKD) is among the most common monogenic disorders mainly associated with PKD1/PC1 mutations. We show herein that renal regulation in Pc1 dosage-reduced and -increased mouse models converge toward stimulation of c-Myc expression along with β-catenin, delineating c-Myc as a key Pkd1 node in cystogenesis. Enhanced renal c-Myc-induced ADPKD in SBM transgenic mice lead conversely to striking upregulation of Pkd1/Pc1 expression and β-catenin activation, lending credence for reciprocal crosstalk between c-Myc and Pc1.

[Evaluation of a citizenship-oriented intervention: The Citizens' Project of the University of Recovery].

Objectives The Global Model of Public Mental Health is "global" not only in the sense of having an international perspective, but in regarding service users as actors at all levels of public mental health exerting collective and organized influence on the social determinants of health, in addition to being recipients of care. Having access to appropriate health and mental health care when needed is a fundamental human right. Having a say over the manner in which care is provided, including partnership in decision making in care planning and ongoing care, has gained increasing support among recipients and providers of care.

Ideological roadblocks to humanizing dentistry, an evaluative case study of a continuing education course on social determinants of health.

Background: Front line providers of care are frequently lacking in knowledge on and sensitivity to social and structural determinants of underprivileged patients' health. Developing and evaluating approaches to raising health professional awareness and capacity to respond to social determinants is a crucial step in addressing this issue. McGill University, in partnership with Université de Montréal, Québec dental regulatory authorities, and the Québec anti-poverty coalition, co-developed a continuing education (CE) intervention that aims to transfer knowledge and improve the practices of oral health professionals with people living on welfare.

Lack of Clinical Benefit of Thromboprophylaxis in Patients Hospitalized in a Medical Unit Over a 10-year Span.

Background: Thromboprophylaxis for hospitalized patients with a high risk of venous thromboembolic events (VTEs) is strongly recommended but is not universally applied on medical units. Outside of randomized trials, there is minimal evidence that the usual medications reduce the incidence of clinically significant VTE.

Methods: We conducted a retrospective cohort study including all patients admitted into a teaching medical unit during years 2001-2002, 2003-2004, 2005-2006, 2007-2008 and 2009-2010.

Evidence for a novel mechanism independent of myocardial iron in β-thalassemia cardiac pathogenesis.

Human β-thalassemia major is one of the most prevalent genetic diseases characterized by decrease/absence of β-globin chain production with reduction of erythrocyte number. The main cause of death of treated β-thalassemia major patients with chronic blood transfusion is early cardiac complications that have been attributed to secondary iron overload despite optimal chelation. Herein, we investigated pathophysiological mechanisms of cardiovascular dysfunction in a severe murine model of β-thalassemia from 6 to 15-months of age in the absence of confounding effects related to transfusion.
