Gross morphologic features of surgical specimen in rectal cancer patients with pathological complete response following neoadjuvant chemoradiotherapy: A cross-sectional study.

Background: pathological complete response (pCR) is achieved in 10%-30% of rectal cancer patients following neoadjuvant chemoradiotherapy and surgery. Residual mucosal abnormalities, which make patients ineligible for nonoperative management, may not be an accurate indicator of the pCR. The purpose of this study was to report the gross findings of rectal cancer patients with pathological complete responses.

The impact of circular stapler size on the risk of anastomotic stricture following total mesorectal excision in rectal cancer patients: A retrospective cross-sectional study.

Introduction: Colorectal cancer (CRC) surgery complications are a major issue affecting morbidity and mortality rates. Anastomotic stricture, which occurs in almost 30% of patients after surgery for rectal cancer, is one of the most serious but underreported side effects. In this study, we tried to assess the effect of stapler size on anastomotic stricture rate.

The Association of Seasonal Variations and COVID-19 Clinical Features: A Comparative Study on the Fourth and Fifth Waves.

Purpose: The COVID-19 pandemic has overwhelmed many healthcare systems. Seasonality is a feature of several infectious diseases. Studies regarding the association of seasonal variations and COVID-19 have shown controversial results.

Burnout in Surgical Residents of an Academic Hospital in Iran: A Cross-Sectional Study.

Background: Academic burnout has adverse effects on residents' professional behavior as well as personal aspects of their lives and can ultimately affect their performance in the workplace. This study aimed to determine the prevalence of burnout among surgical residents in Imam Khomeini hospital and the relationship between factors such as sex, marital status, living place, specialized field, and anxiety with burnout.

Methods: We conducted a cross-sectional study in 2021.

Association of fruits, vegetables, and fiber intake with COVID-19 severity and symptoms in hospitalized patients: A cross-sectional study.

Background And Aims: Fruits and vegetables are rich in fiber and a good source of anti-inflammatory and immune-boosting vitamins, minerals, and antioxidants. We investigated the association between fruits, vegetables, and fiber intake and severity of COVID-19 and related symptoms in hospitalized patients.

Methods: A total of 250 COVID-19 hospitalized patients aged 18 to 65 years were recruited for this cross-sectional study in Kashan, Iran, between June and September of 2021.

The impact of the COVID-19 pandemic on surgical education: A survey and narrative review.

Background: Since the emergence of the COVID-19 pandemic, medical education has been a concerning issue, especially in surgical fields. Due to the postponement of many elective surgeries and even alternations in the pattern of emergent surgeries, concerns have been raised about whether residents of surgical disciplines are experienced enough after graduation or not. We aimed to describe the impact of the COVID-19 pandemic on surgical residency training in different fields.

A huge preperitoneal collection following acute necrotizing pancreatitis: A case report and the management approach.

Introduction And Importance: Fluid collection is a critical complication of acute necrotizing pancreatitis. It is usually formed near the pancreas, but unusual collection sites have also been reported. Anterior extraperitoneal or preperitoneal collections following acute pancreatitis are rare and must be differentiated from pancreatic ascites, which is a collection of fluid in peritoneal cavity.

Predicting Risk Score for Mechanical Ventilation in Hospitalized Adult Patients Suffering from COVID-19.

Background: COVID-19 has become a pandemic since December 2019, causing millions of deaths worldwide. It has a wide spectrum of severity, ranging from mild infection to severe illness requiring mechanical ventilation. In the middle of a pandemic, when medical resources (including mechanical ventilators) are scarce, there should be a scoring system to provide the clinicians with the information needed for clinical decision-making and resource allocation.
