Approximately 3800 patients who underwent elective cardiac surgery were analyzed for post-surgical acute kidney injury (AKI). AKI occurred in 21% of patients who initiated a statin within 100 days prior to surgery compared with 29% of patients without prior statin use. The adjusted relative risk for the effect of statin initiation on AKI was RR = 0.86 (95% CI: 0.74, 0.98). Thus, presurgical statin initiation is associated with a reduction in AKI risk after cardiac surgery.

Using data from the National Cancer Data Base, the surgical and oncologic efficacy of minimally invasive (VATS, robotic) lobectomy were compared to open lobectomy. Groups were created for comparison using propensity score matching techniques. VATS compared to open was associated with shorter LOS, higher readmission rates, and slightly better 2-year survival. Nodal upstaging and 30-day mortality were similar. No differences were identified comparing VATS to robotic resections for nodal upstaging, 30-day mortality, or 2-year survival.

This retrospective study of 434 infants and children undergoing TOF repair focused on how methods of handling hypoplastic pulmonary arteries affects long-term outcomes. The most agressive patching technique resulted in the highest incidence of reintervention, whereas patients who had no intervention for hypoplastic pulmonary arterties had the lowest incidence of reintervention. This suggests that patching restricts the growth potential of the native vessels, and indicates that patients generally do better without intervention.

This literature review evaluated 21 studies that included nearly 4000 patients having undergone transcatheter aortic valve implantation (TAVI), specifically focusing on prosthesis-patient mismatch (PPM). Overall prevalence of PPM was 35%, with 8% of patients having severe PPM. PPM occurred less often after TAVI than after surgical AVR. PPM was not associated with increased long-term mortality.

Outcomes of tricuspid valve replacement at a single institution over a 4 decade period were reviewed. A bioprosthesis was used in 82%, and the surgical mortality was nearly 28%. Freedom from structural deterioration was better in the mechanical valve group. Mechanical valves were, however, associated with earlier and more severe morbidity, including a significantly higher incidence of thromboembolic complications.

Surgical intervention in older people is increasing in prevalance but is associated with higher rates of adverse postoperative outcomes as compared to younger people. Current models of preoperative risk assessment and optimisation may be indequate for this complex surgical population. In this article, the Authors discuss the challenges and potential solutions in the establishment of quality surgical care for older people.

Lactic acidosis is a very common biological issue for the postoperative patient with shock. This very nice review addresses thehemodynamic consequences of shock-associated lactic acidosis and highlights the various therapeutic options that can be considered by the bedside clinician.

The optimal timing of tracheotomy in critically ill patients remains a topic of debate. The Authors performed a systematic review to clarify the potential benefits of early versus late tracheotomy. Three categories of timing of tracheotomy (within 4 versus after 10 days, within 4 versus after 5 days, within 10 versus after 10 days) were analyzed. Twelve studies with a total of 2,689 patients were included in this analysis. The Authors have identified that early tracheotomy is associated with more ventilator-free days, shorter ICU stays, less sedation, and reduced long-term mortality, compared to late tracheotomy

The goal of this study was to determine if there is an association between PPI use and incident chronic kidney disease (CKD) in the general population. Two cohorts were studied, the Atherosclerosis Risk in Communities (ARIC), a population based cohort (10,482 subjects followed for a median of 13.9 years) and the Geisinger Health System in Pennsylvania (248,751 subjects followed for a median of 6.2 years). In the ARIC cohort, after adjustment for confounders, the risk of incident CKD was 1.5 times greater in those taking PPIs at baseline compared to those who did not. The 10-year risk of CKD in PPI users at baseline was 11.8% whereas the expected risk (without PPI use) was 8.5%. In the Geisinger Health System cohort, the adjusted risk of incident CKD was 1.17 times greater in PPI users than in those who did not use PPIs. In addition, twice daily dosing of PPIs was associated with a greater risk of CKD than once daily dosing. This observational cohort study identified an association between PPI use and incident CKD, but does not provide evidence to prove causality.

In this trial 2100 undergoing coronary surgery were randomized to aspirin 100mg or placebo. The primary outcome was defined as a composite of death and thrombotic complications (myocardial infarction, stroke, pulmonary embolism, renal failure or bowel infarction) at 30 days.
There was no difference between the two treatment groups for the primary endpoint (aspirin group 19.3% versus placebo group 20.4% , p=0.55). Other endpoints included cardiac tamponade (aspirin group 1.1% versus placebo 0.4%, p=0.08) and major hemorrhage leading to reoperation (aspirin group 1.8% versus placebo 2.1%, p=0.75).
The authors conclude that preoperative aspirin did not lead to a higher risk of death, thrombotic complications or reoperation due to bleeding.
