Background: The aim of this study was to evaluate the incidence, clinical impact and outcome of perioperative myocardial infarction (PMI) in patients undergoing pancreatic surgery.
Methods: A data of 1,625 patients undergoing pancreatic resection were prospectively collected and analysed with regard to PMI. Demographic aspects, co-morbidities and clinical course were evaluated. Cardiac risk factors (ASA and NYHA), postoperative complications and mortality were compared in a match-pair analysis (1:3) with patients without PMI.
Results: Twenty-nine patients with PMI after pancreatic surgery were identified. PMI occurred after all types of pancreatic operations and was observed most frequently (72.2%) within the first postoperative week. In a total of 90%, PMI fulfilled the criteria of non-STEMI. Nearly half of the patients (48%) were clinically asymptomatic. Both ASA III and heart failure were more frequent in patients with PMI. The in-hospital mortality was significantly increased after PMI (p < 0.002), with post-pancreatectomy haemorrhage (PPH) as the most relevant underlying risk factor.
Conclusion: PMI is a rare but severe complication after pancreatic operations, contributing significantly to in-hospital mortality. Clinical management mainly includes an anti-coagulant approach. This may be related with an increased risk for PPH. Therefore, the use of anti-coagulant drugs in the early postoperative period-especially in asymptomatic patients-should be critically evaluated.

Cardiovascular diseases such as stroke are a major cause of morbidity and mortality for patients with chronic kidney disease (CKD). The underlying mechanisms connecting CKD and cardiovascular disease are yet to be fully elucidated, but inflammation is proposed to play an important role based on genetic association studies, studies of inflammatory biomarkers, and clinical trials of anti-inflammatory drug targets. There are multiple sources of both endogenous and exogenous inflammation in CKD, including increased production and decreased clearance of proinflammatory cytokines, oxidative stress, metabolic acidosis, chronic and recurrent infections, dialysis access, changes in adipose tissue metabolism, and disruptions in intestinal microbiota.

Background: Ciliary neurotrophic factor (CNTF), mainly known for its neuroprotective properties, belongs to the IL-6 (interleukin-6) cytokine family. In contrast to IL-6, the effects of CNTF on the vasculature have not been explored. Here, we examined the role of CNTF in AngII (angiotensin II)-induced hypertension.

It has the potential to alter the growth of the head or acetabulum and prevent the best outcomes. While past literature has evaluated the risks of AVN and strategies to avoid it, studies on the impact of AVN on the outcomes are scarce.

Background: The pathogenic distribution of co-infections and immunological status of patients infected with human adenovirus serotypes 3 or 7 (HAdV-3 or HAdV-7) were poorly understood.
Methods: This study involved a retrospective analysis of respiratory specimens collected from enrolled children with lower respiratory tract infections (LRTIs), positive for HAdV-3 or HAdV-7 from January 2017 to December 2019. Demographic data, clinical features, laboratory and radiographic findings were compared to delineate the impact of co-infections, and immune responses on clinical severity of HAdV-3 or HAdV-7 infections.
