With the emergence of high-quality sequencing technologies, further research on transcriptomes has become possible. Circular RNA (circRNA), a novel type of endogenous RNA molecule with a covalently closed circular structure through "back-splicing," is reported to be widely present in eukaryotic cells and participates mainly in regulating gene and protein expression in various ways. It is becoming a research hotspot in the non-coding RNA field.

Investigate the impact of antimicrobial photodynamic therapy (aPDT) using different photosensitizers (PSs) such as indocyanine green (IG), curcumin (CC), and methylene blue (MB), with or without intracanal application of calcium hydroxide (CH), on the push-out bond strength of glass-fiber posts (GFPs) to intraradicular dentin, the chemical composition of the root substrate, and the sealing of the adhesive interface across different thirds of intraradicular dentin. A total of 112 bovine teeth underwent biomechanical preparation and were divided into eight experimental groups (n = 14 each): Negative control with deionized water; positive control with deionized water + CH; IG group with indocyanine green and infrared laser; IG + CH group; CC group with curcumin and blue LED; CC + CH group; MB group with methylene blue and red laser; and MB + CH group. The push-out bond strength was measured using a universal testing machine (n = 8), and scanning electron microscopy characterized the fracture patterns.

Artificial intelligence (AI) offers promising solutions for many steps of the cardiac imaging workflow, from patient and test selection through image acquisition, reconstruction, and interpretation, extending to prognostication and reporting. Despite the development of many cardiac imaging AI algorithms, AI tools are at various stages of development and face challenges for clinical implementation. This scientific statement, endorsed by several societies in the field, provides an overview of the current landscape and challenges of AI applications in cardiac CT and MRI.

AbstractScreening and treatment of asymptomatic bacteriuria is generally not recommended due to a lack of clinical benefit and potential harm. A notable exception is the recommendation for routine screening during pregnancy. In this Tomorrow's Trial, the authors review the relevant evidence and propose a trial to address the question, "should low-risk pregnant patients be screened for asymptomatic bacteriuria?"

Background: Acute ischemic stroke (AIS) from distal medium vessel occlusion (DMVO) presents unique treatment challenges. Mechanical thrombectomy (MT) is emerging as a viable option for these patients, yet the role of pre-stroke aspirin treatment is unclear. This study evaluates the impact of pre-stroke low-dose aspirin on outcomes in DMVO patients undergoing MT.

Background: Preventing postoperative atrial fibrillation (POAF) as one of the most significant complications of cardiovascular surgeries remains a major clinical challenge. We conducted a systematic review with network meta-analysis of randomized controlled trials, to identify the most effective and safe anti-inflammatory drugs to prevent new-onset POAF.
Methods: MEDLINE, Embase, Web of Science, and Cochrane Library were searched without language or publication-date restriction on August 8, 2022 (updated on August 8, 2023).

Sudden cardiac death is a leading cause of mortality in children with hypertrophic cardiomyopathy (HCM). The PRecIsion Medicine in CardiomYopathy consortium developed a validated tool (PRIMaCY) for sudden cardiac death risk prediction to help with implantable cardioverter defibrillator shared decision-making, as recommended by clinical practice guidelines. The mplemeting a udden Cardiac Dath isk Assessment ool in hildhood (INSERT-HCM) study aims to implement PRIMaCY into electronic health records (EHRs) and assess implementation determinants and outcomes.

Background: Guideline-directed medical therapy (GDMT) reduces events in patients with heart failure (HF) with reduced ejection fraction (HFrEF). Despite this impact, underutilization of GDMT persists. This report sought to describe HF management in Canadian outpatients treated at specialized HF clinics (HFCs).

This review examines the cardiovascular risks associated with the use of non-steroidal anti-inflammatory drugs (NSAIDs), both traditional NSAIDs and cyclooxygenase-2 selective inhibitors (COXIBs). It describes the history of traditional NSAIDs and the development of COXIBs to explain why their cardiovascular side effects were unnoticed for many decades. Further, the review presents the mechanism of action of NSAIDs, to elucidate the possible underlying basis for why they are associated with an increased risk of cardiovascular disease.

Introduction: Adults over the age of 65 are at a higher risk for diagnostic errors due to a myriad of reasons. In primary care settings, a large contributor of diagnostic errors are breakdowns in information gathering and synthesis throughout the patient-provider encounter. Diagnostic communication interventions, such as the Agency for Healthcare Research and Quality's "Be the Expert on You" note sheet, may require adaptations to address older adults' unique needs.

Despite the recognition by key guidelines that achieving early glycaemic control has important benefits in individuals with type 2 diabetes (T2D) and that addressing excess adiposity is one of the central components of comprehensive person-centred T2D care, a substantial proportion of individuals with T2D do not meet their metabolic treatment goals. Prior treatment paradigms were limited by important treatment-associated risks such as hypoglycaemia and body weight gain. Therefore, a more conservative, sequential approach to treatment was typically utilized.

Peritoneal dialysis (PD) and kidney transplantation are important therapeutic options in patients with advanced kidney disease. This article delineates the relationship between PD and kidney transplantation in several key domains, including: (1) Comparative merits and limitations of PD versus center-based hemodialysis prior to kidney transplantation, (2) Patient outcomes after kidney transplantation in individuals receiving PD prior to kidney transplantation, (3) Perioperative management strategies of patients receiving PD at the time of kidney transplantation, and (4) The relative advantages and clinical outcomes of PD use following kidney allograft failure compared to other modalities. This article aims to provide comprehensive guidance for optimizing care across the PD-kidney transplant transitions continuum.

The GLP-1 receptor-based agonists (GLP-1RAs) and SGLT2 inhibitors (SGLT2i) are major 21 century breakthroughs in diabetes and obesity medicine but there are important safety considerations regarding the perioperative and periprocedural management of individuals who are treated with these agents. GLP-1RAs have been linked to an increased risk of retained gastric contents and pulmonary aspiration while SGLT2i can be associated with diabetic ketoacidosis. This manuscript provides a narrative review of the available evidence for perioperative and periprocedural risks in people prescribed GLP-1RAs and SGLT2i.

The field of medicine is constantly changing and, as healthcare providers, we are fortunate to be practicing in a time when patients are living longer and novel therapeutic options continue to evolve. However, these new advances may be associated with adverse effects that practitioners need to be aware of. Some of these impair the immune system leading to secondary immunodeficiencies (SID) that increase host susceptibility to infections and other complications.
