Summary: The use of ureteral stents in colorectal surgeries does not increase the risk of acute kidney injury (AKI) in patients under 60 years old. However, for women and patients over 60, the use of stents poses a higher risk of transient AKI. The overall incidence of AKI in our single-institution community hospital population was significantly lower than reported in other studies. There was no statistical difference in AKI incidence between lighted and non-lighted stents.

Summary: The study found that the incidence rate of ureteral injuries during open colorectal surgery is increasing over time, while the injury rates for MIS cases have been stable or decreasing. These findings remain consistent even after propensity score analysis. Further research is needed to better understand the impact of MIS and robotic-assisted surgery on ureteral injuries.

Summary: This study found no significant difference in the incidence of postoperative AKI between laparoscopic and open surgery in patients with colorectal cancer. However, laparoscopic surgery was associated with better outcomes in terms of ICU admission, complications, hospital stay, and 1-year mortality.

Summary: This study evaluated the intraoperative utility of NIRFUC in 20 patients undergoing colorectal surgery. The ureters were clearly identified without the need for dissection, and there were no cases of ureteral injury. Fluorescence ureteral navigation using NIRFUC may facilitate colorectal surgery, especially in complex cases.

Summary: This study found that approximately one quarter of patients undergoing surgery for acute type A aortic dissection will develop AKD. Patients with AKD, with or without AKI, are at higher risk for MAKEs and readmission. Higher-stage AKD is associated with a trend of persistent decline in kidney function.

Summary: Acute kidney injury (AKI) is a serious complication after vascular surgery and impaired NAD+ synthesis may contribute to its development in these patients. Elevated postoperative quinolinate to tryptophan ratios were associated with AKI, and higher preoperative quinolinate concentrations and postoperative ratios were associated with greater postoperative creatinine increases.

Summary: The study found that decreased preoperative uromodulin levels are independently associated with an increased risk of acute kidney injury (AKI) and perioperative kidney dysfunction after cardiac surgery.

Summary: Elevated renin concentrations are associated with cardiovascular instability and increased AKI after cardiac surgery. Elevated renin concentrations could be used to identify high-risk patients for cardiovascular instability and AKI who would benefit from timely intervention that could improve their outcomes.

Summary: Acute kidney injury after cardiac surgery presents specific patterns of damage and recovery, which are crucial for management and outcomes. The KDIGO classification only partially covers the conceptual framework and is insufficient for a comprehensive diagnosis. This review discusses the strengths and limitations of recent criteria for CSA-AKI and provides an overview of biomarkers. The evolving understanding of CSA-AKI as a time-sensitive condition has led to an increased demand for enhancing diagnostic criteria and implementing biomarkers in clinical practice.

Summary: The study revealed that postoperative AKI in valvular heart surgery patients increases the risk of AKD and CKD development, with persistent AKI further escalating this risk. Additionally, heart failure and high right ventricular pressure postoperatively were identified as independent risk factors for CKD.

Summary: Preoperative cardiac, inflammatory, renal, and metabolic biomarkers are associated with CSA-AKI and may improve identification of patients at risk. The use of a biomarker panel may enhance the identification of patients with CSA-AKI compared to using only clinical risk factors.

Summary: This study aimed to report the incidence of iatrogenic ureteral injury (IUI) during colorectal surgery and analyze the long-term consequences of urological late complications and their impact on oncological outcomes. The results showed that IUI has few consequences if recognized early, but long-term urological sequelae can occur in a third of patients and may affect the timing of adjuvant chemotherapy in colorectal surgery.

Summary: Arterial switch operations (ASO) are performed on neonates to treat transposition of the great arteries, but future operations on the neoaorta may be required due to dilation. We present a unique case of a 25-year-old female who required a David procedure for neoaorta dilation due to the anterior lie of the pulmonary artery after ASO. Our approach to this patient's surgery with the unique anatomy is described.

Summary: This study investigated the employment status after heart transplant and identified factors influencing employment. The study found that approximately 22% of patients were employed at 1 year post-transplant, and this increased to 32% at 2 years. Employment was associated with factors such as being white, male, having prior job experience, and having private insurance. The study also found that employment was associated with decreased mortality risk, with employed individuals having a 26% lower risk of mortality.

Summary: This study evaluated the effect of cardiopulmonary bypass (CPB) on COVID-19 vaccination antibody concentration after cardiac surgery. The results showed that antibody concentration was significantly reduced in the short-term following CPB but returned to pre-CPB levels within 1 month. Heightened precautions in the perioperative period for cardiac surgery patients may be necessary.
