Aim: To investigate plasma Monocyte Chemotactic Protein-1 levels preoperatively in colorectal cancer (CRC) and benign patients and postoperatively after CRC resection.
Methods: A plasma bank was screened for minimally invasive colorectal cancer resection (MICR) for CRC and benign disease (BEN) patients for whom preoperative, early postoperative, and 1 or more late postoperative samples (postoperative day 7-27) were available. Monocyte chemotactic protein-1 (MCP-1) levels (pg/mL) were determined via enzyme linked immuno-absorbent assay.
Results: One hundred and two CRC and 86 BEN patients were studied. The CRC patient's median preoperative MCP-1 level (283.1, CI: 256.0, 294.3) was higher than the BEN group level (227.5, CI: 200.2, 245.2; P = 0.0004). Vs CRC preoperative levels, elevated MCP-1 plasma levels were found on postoperative day 1 (446.3, CI: 418.0, 520.1), postoperative day 3 (342.7, CI: 320.4, 377.4), postoperative day 7-13 (326.5, CI: 299.4, 354.1), postoperative day 14-20 (361.6, CI: 287.8, 407.9), and postoperative day 21-27 (318.1, CI: 287.2, 371.6; P < 0.001 for all).
Conclusion: Preoperative MCP-1 levels were higher in CRC patients (vs BEN). After MICR for CRC, MCP-1 levels were elevated for 1 mo and may promote angiogenesis, cancer recurrence and metastasis.

Clinical Research Development Unit, Shafa Hospital, Kerman University of Medical Sciences, Kerman, Iran.
Background: This study aimed to investigate the major predictive factors associated with prolonged mechanical ventilation(PMV) following cardiac surgery.
Methods: This retrospective, cross-sectional, descriptive-analytical study was conducted from September 2021 to March 2022, involving 244 patients who underwent cardiac surgery. PMV was defined as mechanical ventilation for more than 24 h.
Hyponatremia is associated with malignant brain edema after mechanical thrombectomy in acute ischemic stroke.
BMC Neurol

Neurological Disorder Center, Department of Cerebrovascular Disease, Suining Central Hospital, Sichuan, 629000, China.
Background: Hyponatremia (< 135 mmol/L) is the most common electrolyte disturbance in patients with stroke. However, few studies have reported the relationship between hyponatremia at admission and outcomes in patients with acute ischemic stroke (AIS) treated with mechanical thrombectomy (MT). This study is aimed to explore the association between hyponatremia and clinical outcomes following MT.

Hepatopancreatobiliary Center, Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University, Beijing, China.
Purpose: To investigate the risk factors for late postoperative pancreatic fistula (POPF) following pancreaticoduodenectomy (PD), with a focus on positive drain fluid culture (DFC) results on postoperative day (POD) 1.
Methods: Medical records of 198 patients who underwent PD with drain fluid amylase (DFA) on POD 5 < 3x upper limit of normal (ULN) were included. Late POPF was defined as POPF diagnosed post-POD 6, with DFA on POD 5 < 3xULN.
Validation of mortality risk scores after esophagectomy.

Department of General, Visceral and Transplantation Surgery, University Hospital Heidelberg, Heidelberg, Germany.
Purpose: Oncological esophagectomy is the mainstay in esophageal cancer treatment, but perioperative mortality remains a significant concern. Various scoring systems exist to identify patients at high risk for postoperative complications and death. In the following, we aim to evaluate and compare these different scoring systems.

Division of General and Foregut Surgery, University of Milan, IRCCS Policlinico San Donato, San Donato Milanese (Milano), Italy.
Purpose: Anastomotic leakage (AL) is one of the most important complications that occurs after upper gastrointestinal surgery, registering rates of 20-30% after esophagectomy. The role of systemic inflammatory biomarkers to predict anastomotic leaks is controversial and needs systematization.
Methods: A systematic review based on the PRISMA guidelines criteria was performed.
