Predictive potential of pre-procedural cardiac and inflammatory biomarkers regarding mortality following transcatheter aortic valve implantation: A systematic review and meta-analysis.

Background: Aortic stenosis (AS) is a common heart valve disease, especially in aging populations. While surgical aortic valve replacement (SAVR) is the standard treatment, many patients are ineligible. Transcatheter aortic valve implantation (TAVI) offers an alternative, especially for high-risk patients, but is not without complications.

Periprocedural Changes of Serum Biomarkers in Predicting Complications Following Bariatric Surgery for Obesity: Systematic Review and Meta-analysis.

Bariatric surgery is an effective treatment for severe obesity, but complications and peri-operative monitoring are important considerations. We conducted a comprehensive review of studies assessing pre-operative biomarkers and complications in patients undergoing bariatric surgery. A total of 14 studies were included.

Incidence of atrioventricular block after isolated coronary artery bypass grafting: a systematic review and pooled-analysis.

Background And Objectives: Atrioventricular block (AVB) is a serious complication following coronary artery bypass grafting (CABG) surgery, and its high-grade form may necessitate the implantation of a permanent pacemaker (PPM). AVB is associated with increased morbidity and mortality rates. This study aims to estimate the incidence of AVB and subsequent PPM implantation after isolated CABG surgery.

Sinus node dysfunction and related permanent pacemaker implantation after major cardiac surgeries, systematic review, and meta-analysis.

Background: There is no concise evidence or clinical guidelines regarding the incidence of sinus node dysfunction (SND) and permanent pacemaker (PPM) implantation following cardiac surgeries and their management approaches.

Objective: We aim to systematically review current evidence on the prevalence of SND, PPM implantation concerning it, and its risk factors in patients undergoing cardiac surgery.

Method: Four electronic databases (Cochrane Library, Medline, SCOPUS, and Web of Science) were systematically searched for articles regarding SND after cardiovascular surgeries and reviewed by two independent researchers, and a third review in case of discrepancies.

COVID-19 Infection Risk Following Elective Arthroplasty and Surgical Complications in COVID-19-vaccinated Patients: A Multicenter Comparative Cohort Study.

Background: We aimed to determine symptomatic Coronavirus disease 2019 (COVID-19) rates within 1 month of elective arthroplasty for vaccinated individuals and to determine whether vaccination guarantees protection against COVID-19 after arthroplasty (primary outcome). In addition, the 90-day surgical complications were compared to those of an unvaccinated group (secondary outcome).

Methods: A prospective cohort study was conducted on elective joint arthroplasty patients at 3 tertiary hospitals in 2 major cities (Tehran and Isfahan) in our country (Iran).

Teaching professionalism in cadaver dissection: medical students' perspective.

This study was designed to facilitate freshman medical students' adaptation to the dissection room and familiarize them with the related ethical codes. Single-group post-test design research was conducted at Tehran University of Medical Sciences in 2018 - 2019. The program began with a brief explanation of the necessity of the subject, and after a documentary film was shown, the principles of professional and ethical behaviors in the dissection room were discussed by a panel of experts.
