Changes of serum cell adhesion molecules as potential markers of inflammation severity, metabolic status and mortality in patients infected with COVID-19.

Acute-phase viral infections, such as COVID-19, trigger a complex interplay of proinflammatory and regulatory responses, influencing both tissue repair and damage. Intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and platelet endothelial cell adhesion molecule-1 (PECAM-1) play crucial roles in immune activation, regulation, and homeostasis during infection. This study included adult patients hospitalized at the University Hospital in Cracow, Poland, with confirmed SARS-CoV-2 infection between January and June 2021.

Epigenetic Abnormalities in Chondrosarcoma.

In recent years, our understanding of the epigenetic mechanisms involved in tumor pathology has improved greatly. DNA and histone modifications, such as methylation, demethylation, acetylation, and deacetylation, can lead to the up-regulation of oncogenic genes, as well as the suppression of tumor suppressor genes. Gene expression can also be modified on a post-transcriptional level by microRNAs that contribute to carcinogenesis.

Quest for the optimal technique of laparoscopic splenectomy - vessels first or hilar transection?

Introduction: Throughout our 20 years of experience, we have used several different techniques for laparoscopic splenectomy (LS). However, two methods have been used most frequently: "vessels first" and "hilar transection".

Aim: To evaluate the outcomes of LS performed with these two different approaches.

Transanal total mesorectal excision for low rectal cancer: a case-matched study comparing TaTME versus standard laparoscopic TME.

Background: Transanal total mesorectal excision (TaTME) is emerging as a novel alternative to laparoscopic total mesorectal excision (LaTME). The aim of this study was to compare clinical and pathological results from these two techniques in patients undergoing rectal resections because of low rectal cancer.

Materials And Methods: Thirty-five patients undergoing TaTME were matched with 35 patients operated on using LaTME.

Defunctioning ileostomy reduces leakage rate in rectal cancer surgery - systematic review and meta-analysis.

Objectives: The role of a defunctioning ileostomy in every anterior rectal resection with total mesorectal excision (TME) is still controversial. In this study, we aimed to review the current literature to determine the impact of ileostomy creation on postoperative outcomes in patients undergoing anterior rectal resection with TME.

Methods: MEDLINE, Embase and Cochrane Library were searched for eligible studies.

More stapler firings increase the risk of perioperative morbidity after laparoscopic sleeve gastrectomy.

Introduction: Staple-line bleeding and leakage are the most common serious complications of laparoscopic sleeve gastrectomy. The relationship between multiple stapler firings and higher risk of postoperative complications is well defined in colorectal surgery but has not been addressed in bariatric procedures so far. Identification of new factors such as "the numbers of stapler firings used during laparoscopic sleeve gastrectomy (LSG)" as a predictor for complications can lead to optimization of the patient care at bariatric centers.

Therapeutic effect of exogenous ghrelin in the healing of gingival ulcers is mediated by the release of endogenous growth hormone and insulin-like growth factor-1.

Ghrelin, an acylated 28-amino acid polypeptide, was primary isolated from the stomach, and the stomach is a main source of circulating ghrelin. Ghrelin strongly and dose-dependently stimulates release of growth hormone from the anterior pituitary, as well as increases food intake and fat deposition. Previous studies showed that ghrelin exhibits protective and therapeutic effect in different parts of the gastrointestinal system, including the oral cavity.

Laparoscopic uncinate process first pancreatoduodenectomy-feasibility study of a modified 'artery first' approach to pancreatic head cancer.

Purpose: The aim of this study was to discuss the feasibility of laparoscopic 'uncinate first' pancreatoduodenectomy.

Methods: The analysis included prospectively collected data from 12 consecutive patients undergoing elective pure laparoscopic 'uncinate process first' pancreatoduodenectomy (Group 1). They were compared with patients previously operated on with a classical laparoscopic approach (Group 2).

Patients criteria determining difficulty of the laparoscopic lateral transperitoneal adrenalectomy. A retrospective cohort study.

Background: Identification of patients in whom adrenalectomy may be more difficult, can help in decision making in borderline and doubtful cases. The aim of the study was to determine patients criteria influencing difficulty of laparoscopic lateral transperitoneal adrenalectomy (LTA).

Material And Methods: The study enrolled 275 patients who underwent LTA.

Are we ready for the ERAS protocol in colorectal surgery?

Introduction: Modern perioperative care principles in elective colorectal surgery have already been established by international surgical authorities. Nevertheless, barriers to the introduction of routine evidence-based clinical care and changing dogmas still exist. One of the factors is the surgeon.

Therapeutic Effect of Low Doses of Acenocoumarol in the Course of Ischemia/Reperfusion-Induced Acute Pancreatitis in Rats.

Unlabelled: Intravascular activation of coagulation is observed in acute pancreatitis and is related to the severity of this inflammation.
