Article Synopsis
  • Real-time risk monitoring is essential in ICUs but often struggles with a lack of updates for clinical variables, prompting the development of a new framework that incorporates uncertainties into existing risk assessment systems like the SOFA score.
  • The study analyzed data from 5,351 patients in a Cardiothoracic ICU, utilizing machine learning models to enhance real-time SOFA scores and account for uncertainties, with validation showing improved predictive capabilities for mortality and readmission.
  • Results demonstrated that the new model outperformed traditional SOFA scores and quick SOFA in predicting outcomes, suggesting it could lead to more efficient testing and better patient care in clinical settings.

The long saphenous vein is routinely used for coronary bypass graft (CABG) surgery, and two primary techniques are commonly utilized: endoscopic vessel harvesting (EVH) and open vessel harvesting (OVH). The aim of this study was to compare the clinical outcomes of the EVH and OVH techniques used for CABG within the confines of a tertiary hospital. The clinical data of all patients subjected to either EVH or OVH for CABG surgery between 2014 and 2018 were retrospectively analyzed.

Article Synopsis
  • Deep sternal wound infection (DSWI) is a serious complication following coronary artery bypass grafting (CABG), and this study investigates how glycated hemoglobin (HbA1c) levels affect the risk of DSWI.
  • The meta-analysis included 14 studies with over 15,500 patients, finding a significant correlation between elevated preoperative HbA1c levels and the likelihood of developing DSWI, particularly in diabetic patients.
  • A HbA1c level above 5.7% was associated with increased DSWI risk, with a notable nonlinear relationship indicating the higher the HbA1c, the greater the risk of infection.

Background And Objectives: There is an ongoing controversy regarding the risks of restrictive and liberal red blood cell (RBC) transfusion strategies. This meta-analysis assessed whether transfusion at a lower threshold was superior to transfusion at a higher threshold, with regard to thrombosis-related events, that is, whether these outcomes can benefit from a restrictive transfusion strategy is debated.

Materials And Methods: We searched PubMed, Cochrane Central Register of Controlled Trials and Scopus from inception up to 31 July 2021.

The novel coronavirus disease 2019 (COVID-19) has caused a global pandemic. Some studies have suggested a negative association between sunlight intensity and COVID-19 infection, alluding to the belief that it might be safe to go out on sunny days. This paper examined whether solar radiation mitigated the association between human mobility and COVID-19 infection in Europe using a dynamic panel data model to investigate the effect of human mobility, solar radiation, and their interaction on COVID-19 infection.

Acute kidney injury (AKI) is a frequent complication of cardiac surgery, which can lead to higher mortality and long-term renal function impairment. The effect of perioperative renin-angiotensin system inhibitors (RASi) therapy on AKI incidence in patients undergoing cardiac surgery remains controversial. We reviewed related studies in PubMed, Scopus, and Cochrane Library from inception to February 2020.

Unlabelled: SEPSIS-3 DEFINITION: Sepsis is defined as life-threatening organ dysfunction due to a dysregulated host response to infection. The clinical criteria of sepsis include organ dysfunction, which is defined as an increase of two points or more on the sequential organ failure assessment (SOFA). For patients with infection, an increase of 2 SOFA points yields an overall mortality rate of 10%.

Background: Extubation is a critical step in the intensive care unit (ICU). In this study, we aim to investigate the risk factors for both extubation failure and deterioration with further mechanical ventilation (MV).

Methods: Data were collected from a cardiothoracic ICU in a tertiary hospital.

Background And Objective: Pleural procedures such as tube thoracostomy and chest aspirations are commonly performed and carry potential risks of visceral organ injury, pneumothorax and bleeding. In this context limited information exists on the complication rates when non-pulmonologists perform ultrasound-guided bedside pleural procedures. Bedside pleural procedures in our university hospital were audited to compare complication rates between pulmonologists and non-pulmonologists.

Cell transplantation is a promising new modality in treating damaged myocardium after myocardial infarction and in preventing postmyocardial infarction LV remodelling. Two strategies are plausible: the first uses adult tissue stem cells to replace the scar tissues and amend the lost myocardium, whilst the second strategy uses embryonic stem cells in an attempt to regenerate myocardium and/or blood vessels.

The internal mammary artery (IMA) in patients with small body surface area, frequently found in the Asian population, is often small and delicate and can be easily damaged during suturing, particularly at the "toe" of the anastomosis. This may lead to less frequent utilization of the IMA as a bypass conduit. We describe a technique for anastomosing a small-caliber IMA to a coronary artery, using the tip of the graft as an autologous buttress to reinforce the toe of the anastomosis.
