BACKGROUND: The CovidSurg-Cancer Consortium aimed to explore the impact of COVID-19 in surgical patients and services for solid cancers at the start of the pandemic. The CovidSurg-Gynecologic Oncology Cancer subgroup was particularly concerned about the magnitude of adverse outcomes caused by the disrupted surgical gynecologic cancer care during th...

The pinch-off syndrome is defined as the embolization of the central catheter inserted via the subclavian approach due to the mechanical compression between the clavicle, the first rib, the subclavius muscle, and the costoclavicular ligament. Embolization to the pulmonary artery is an extremely rare condition. In this article, we present a rare cas...

Background The 2015 Lancet Commission on global surgery identified surgery and anaesthesia as indispensable parts of holistic health-care systems. However, COVID-19 exposed the fragility of planned surgical services around the world, which have also been neglected in pandemic recovery planning. This study aimed to develop and validate a novel index...

High expression of immune checkpoint receptors (ICRs) in the tumor microenvironment regulates the anti-tumor response. In this study, the differential expressions of ICRs on tumor-infiltrating lymphocytes (TILs) in patients with early-stage breast cancer were investigated. The study included 32 patients who underwent surgery with a diagnosis of ear...

Machine learning risk prediction of mortality for patients undergoing surgery with perioperative SARS-CoV-2: the COVIDSurg mortality score

Purpose: This study aimed to evaluate the early and long-term results of the three surgical methods (Ferguson hemorrhoidectomy, laser hemorrhoidoplasty, and combined method) of hemorrhoidal disease. Methods: Between January 2018 and January 2020, 154 consecutive patients diagnosed with symptomatic grade II-III hemorrhoid disease were treated with F...

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients.Since surgical patients are already at higher risk of venous thromboembolism than general populations, thisstudy aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk ofvenous thromboembolism. We...

There is little evidence around the potentially protective role of previous Bacillus Calmette-Guerin (BCG) vaccination on postoperative mortality in patients with perioperative SARS-CoV-2 vaccination. Prior BCG vaccination did not protect SARS-CoV-2 infected patients against postoperative pulmonary complications and 30-day mortality.

Background Surgery is the main modality of cure for solid cancers and was prioritised to continue during COVID-19 outbreaks. This study aimed to identify immediate areas for system strengthening by comparing the delivery of elective cancer surgery during the COVID-19 pandemic in periods of lockdown versus light restriction.

To support the global restart of elective surgery, data from an international prospective cohort study of 8492 patients (69 countries) was analysed using artificial intelligence (machine learning techniques) to develop a predictive score for mortality in surgical patients with SARS-CoV-2. We found that patient rather than operation factors were the...

Immune checkpoint receptors (ICRs) were recently found to modulate the anti-tumoral immune response. This study aimed to determine the clinical and pathological associations of ICRs expression on tumor-infiltrating lymphocytes (TILs) in patients with locally advanced breast cancer (LABC) treated with neoadjuvant chemotherapy (NAC). Expressions of I...

Appendix epiploica without a colon in the hernia sac is a rare condition, which is even rarer if it has hypertrophy and presents as an irreducible hernia. We describe a case of appendix epiploica in a 37-year-old male patient with a strangulated right inguinal hernia that was herniated to the right inguinal canal. Considering the superiority of lap...

Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Su...

Gastric adenomyomas are rare benign tumors and most often localized in the gastric antrum. It generally consists of glandular cells and smooth muscle bundles. The size of a GA can be up to 4.5cm and can affect patients any age of their life. In cases with GA most of the patients are asymptomatic. However, non‐specific gastrointestinal symptoms such...

Nevoid hyperkeratosis of the nipple and areola is an extremely rare and benign skin disease of unknown etiology, predominantly seen in childbearing aging women, especially in the second and third decades of life. The disease is characterized by gradually growing verrucous thickening and brown pigmentation of the nipple. Here, we present a case of n...

Introduction: High expression of immune checkpoint receptors in tumor microenvironment reduces antitumor immunity and cause immune evasion of tumor cells. In recent years, immunotherapy trials using PD-1 or PDL-1 inhibitors in advanced triple negative (TN) breast cancer evolved very rapidly. The differential expression of novel immune checkpoint re...

Splenic arteriovenous fistula (SAVF) is a rare clinical entity which occurs due to congenital or acquired causes. Among mostly seen etiologies are trauma, splenectomy, splenic artery aneurysm rupture into the veins and vascular degenerations like atherosclerosis and fibrodysplasia. A 47-year-old male patient was brought to our Trauma and Emergency...
