Article Synopsis
  • The study investigates different strategies for venoarterial extracorporeal membrane oxygenation (V-A ECMO) in patients, examining the effectiveness of various cannulation sites and the use of intra-aortic balloon pump (IABP).
  • Researchers categorized patients into two main groups: those receiving isolated V-A ECMO and those receiving V-A ECMO with IABP, and further divided them based on cannulation sites (e.g., central, axillo-femoral).
  • Results showed no significant differences in organ perfusion across the different cannulation sites or with IABP support, suggesting that the choice of cannulation site should be tailored to individual patient needs rather than based on a one-size-fits-all approach

We have previously shown that CRP < 2.9 mg/L is a better predictor of endoscopic remission (ER) than CRP < 5 mg/L in ulcerative colitis (UC). Here, we prospectively evaluate CRP and FCP cut-offs and compare them in predicting ER and histological remission (HR) in UC.

Department of Molecular Biology and Genetics, Faculty of Science, Istanbul University, 34134 Istanbul, Turkey.

Thoracic aortic dissection (TAD) is a highly lethal disease occurring inside the aortic wall and is characterized by matrix degradation. Matrix metalloproteinases (MMPs) are members of a large endopeptidase family that function in the degradation of the extracellular matrix (ECM) proteins, the maintenance of the ECM, and the regulation of signaling in the aorta. MMPs are found in tissue with their natural inhibitors.

Background: Diabetes foot infection is a very important public health problem that causes serious health problems, mortality, and high health expenditures, and is one of the most important complications of diabetes mellitus. There are concerns that approaches such as limited personal visits to doctors, avoidance of hospitals, and restrictions on nonemergency surgical procedures during the coronavirus disease of 2019 pandemic pose a threat to those with diabetic foot problems, including diabetic foot ulcers (DFUs), ischemia, and infection, resulting in increased limb loss and mortality.

Methods: This multicenter, retrospective, cross-sectional study was conducted in 14 tertiary care hospitals from various regions of Turkey.

August 2024

Department of Anesthesia and Intensive Care, IRCCS San Raffaele Scientific Institute, Milan, Italy; Vita-Salute San Raffaele University, Milan, Italy.

Article Synopsis
  • The study evaluates acute normovolemic hemodilution (ANH) as a method to decrease the need for red blood cell (RBC) transfusions in patients undergoing elective cardiac surgery, aiming to reduce associated risks and costs.
  • It is a randomized controlled trial conducted in various hospitals, where patients are assigned to either receive ANH before surgery or the best available alternative treatment.
  • The primary goal is to see if ANH lowers the percentage of patients requiring RBC transfusion from 35% to 28%, with secondary outcomes including mortality and complications related to kidney and bleeding issues.

Introduction: End-stage kidney disease (ESKD) patients require life-sustaining kidney replacement therapies, with the natural arteriovenous fistula (AVF) being the preferred vascular access due to its low infection risk, high patency, and fewer complications. Factors like vessel diameter, gender, diabetes, age, and surgical technique influence AVF maturation.

Method: Our study focused on short-term AVF creation success, specifically examining estimated glomerular filtration rate (eGFR) levels using the CKD-EPI formula.

Introduction: Naples prognostic score (NPS) based on nutritional and inflammatory parameters can predict response to chemotherapy and overall survival (OS) in many cancer types. However, its significance in metastatic pancreatic cancer (PC) remains unclear. We evaluated the prognostic significance of the NPS in patients with metastatic PC receiving first line chemotherapy.

Objective: In this study, the effect of tocilizumab (TCZ) on lung tissue in lung ischemia-reperfusion (I/R) injury in rats was investigated.

Material And Methods: A total of 24 Wistar rats were divided into 4 equal groups, with 6 rats in each group: Left lung I/R was applied to I/R groups. In the I/R groups, the left lung hilum was clamped for 45 minutes, and then the clamp was removed and reperfused for 120 minutes.

Background:  Surgical incisional approach to the ascending aorta is the main strategic step during valvular and/or subvalvular aortic interventions. Classic aortotomy incisions (transverse or oblique) can be challenging and can cause suboptimal exposure of the aortic root especially for the patients with small aortic annulus or for redo coronary artery bypass patients with patent proximal grafts interposed to the ascending aorta.

Methods:  The Kırali incision was used in 91 patients (including 13 reoperations) who underwent an aortic intervention for valvular and subvalvular pathologies.

Thrombotic events associated with SARS-CoV-2 at the vascular endothelium still remains unclear. The aim of the current study is to determine the relationship between cellular proteins on the (ocular) vascular endothelial surface and the immune thrombotic and/or endotheliopathy process elicited by SARS-CoV-2 using an in-silico modeling. The structural S (spike glycoprotein), N (nucleocapsid protein), M (membrane protein), and E (envelope protein) proteins, an accessory protein (ORF1ab) of SARS-CoV-2 and 158 cellular proteins associated with retinal vascular endothelial cell surface or structure were included in this study for comparison of three-dimensional (3D) structure and sequence.

There is increasing evidence that composite scores based on blood counts, which are reflectors of uncontrolled inflammation in the development and progression of heart failure, can be used as prognostic biomarkers in heart failure patients. The prognostic effects of pan-immune inflammation (PIV) as an independent predictor of in-hospital mortality in patients with acute heart failure (AHF) were evaluated based on this evidence. The data of 640 consecutive patients hospitalized for New York Heart Association (NYHA) class 2-3-4 AHF with reduced ejection fraction were analyzed and 565 patients were included after exclusion.

Article Synopsis
  • * Patients were divided into two groups based on MLN size (<1.05 cm and ≥1.05 cm), finding that those with larger MLNs had worse postoperative outcomes, including longer hospital stays and increased need for blood transfusions.
  • * The research concluded that an MLN size greater than 1.05 cm is associated with poorer survival rates and may serve as a better prognostic indicator than the number of MLNs in stage III CRC patients.

Article Synopsis
  • - The study aimed to assess how the size of the largest metastatic lymph node (MLN) affects postoperative outcomes in patients with stage II-III gastric cancer who had curative surgery.
  • - Results showed that larger MLN sizes were linked to longer hospital stays and worse survival outcomes, with a critical cut-off point of 1.05 cm for predicting mortality.
  • - While a larger MLN size indicated poorer survival, it did not significantly influence the occurrence of major complications following surgery, suggesting the need for further research to clarify these findings.

  • The study focused on evaluating the incidence of thyroid dysfunction (TD) in ICU patients with critical COVID-19, noting that the angiotensin-converting enzyme (ACE) is a primary receptor for the virus and is present in the lungs and other organs like the thyroid.
  • Out of 52 ICU patients, 65.4% had TD, and those with TD showed significantly lower levels of thyroid hormones and higher inflammatory markers, although factors like age and mortality rates did not differ significantly between patients with and without TD.
  • This research indicates a notable incidence of thyroid dysfunction in critical COVID-19 patients and highlights the need for monitoring thyroid levels in those severely affected by the virus.

Coverage of the left subclavian artery origin is required to achieve adequate proximal seal during up to 40% of TEVAR cases. The evidence regarding left subclavian artery revascularization in patients undergoing elective or emergent TEVAR with left subclavian artery coverage is weak, and there is ongoing debate whether revascularization should be performed routinely of selectively. Beyond this debate, there is a lack of data about left subclavian artery coverage during TEVAR in end-stage renal disease patients with a functional left upper limb atreriovenous fistula.
