The effect of preoperative cardiac troponin level on outcomes after coronary artery bypass grafting (CABG) is unclear. We investigated the impact of preoperative cardiac troponin I (cTnI) level as well as the time interval between maximum cTnI and surgery on CABG outcomes.

All patients who underwent isolated CABG at our institution between 2009 and 2016 and had preoperative cTnI level available were identified using our Society of Thoracic Surgeons registry. Receiver operating characteristic (ROC) analysis was performed to identify a cTnI threshold level. Subjects were divided into groups based on this value and outcomes compared.

A total of 608 patients were included. ROC analysis identified 5.74 µg/dL as the threshold value associated with worse postoperative outcomes. Patients with peak cTnI >5.74 µg/dL underwent CABG approximately 1 day later, had twice the risk of adverse postoperative events, and had 2.8 day longer postoperative length of stay than those with peak cTnI ≤5.74 µg/dL. cTnI level was not associated with mortality or 30-day readmission. Time interval between peak cTnI and surgery did not affect outcomes.

Elevated preoperative cTnI level beyond a certain threshold value is associated with adverse postoperative outcomes but is not a marker for increased mortality. Time from peak cTnI does not affect postoperative outcomes or mortality and may not need to be considered when deciding timing of CABG.

Regulator of chromosome condensation 1 (RCC1) repeat proteins are phylogenetically widespread and implicated in protein-protein interactions, such as the activation of the small GTPase Ran by its cognate guanine nucleotide exchange factor, RCC1. Legionella pneumophila and Coxiella burnetii, the causative agents of Legionnaires' disease and Q fever, respectively, harbour RCC1 repeat coding genes. LEE011 Legionella pneumophila secretes the RCC1 repeat 'effector' proteins LegG1, PpgA and PieG into eukaryotic host cells, where they promote the activation of the pleiotropic small GTPase Ran, microtubule stabilisation, pathogen vacuole motility and intracellular bacterial growth as well as host cell migration. The RCC1 repeat effectors localise to the pathogen vacuole or the host plasma membrane and target distinct components of the Ran GTPase cycle, including Ran modulators and the small GTPase itself. Coxiella burnetii translocates the RCC1 repeat effector NopA into host cells, where the protein localises to nucleoli. NopA binds to Ran GTPase and promotes the nuclear accumulation of Ran(GTP), thus pertubing the import of the transcription factor NF-κB and innate immune signalling. Hence, divergent evolution of bacterial RCC1 repeat effectors defines the range of Ran GTPase cycle targets and likely allows fine-tuning of Ran GTPase activation by the pathogens at different cellular sites.
Differences in saccadic eye movements are widely reported in mental illnesses, and can indirectly inform our understanding of neurobiological and cognitive underpinnings of psychiatric conditions, including anorexia nervosa (AN). Preliminary research has suggested that individuals with AN may show specific eye movement abnormalities; whether these deficits are representative of state or trait effects is, however, unclear. The aim of this study was to identify whether there are demonstrable differences in performance on saccadic eye movement tasks in individuals with current AN (c-AN), those who are weight-restored from AN (wr-AN), biological sisters of individuals with AN (AN-sis), and healthy controls (HC).

Eighty participants took part in the study (n = 20/group). A set of saccadic eye movement tasks was administered, including prosaccade, antisaccade, memory-guided saccade, and visual scanpath tasks.

The c-AN group showed an increased rate of inhibitory errors to 10° targets on the memory-guided saccade task.

The results are discussed in terms of the potential role of the superior colliculus in AN, and that the findings may reflect a state measure of AN.

The decision of whether to continue oral anticoagulation therapy (OAT) after successful surgical ablation of atrial fibrillation is challenging, and current guidelines provide no specific recommendations on whether or not it is safe to terminate OAT. Therefore, the aim of this study was to assess long-term outcomes in patients who either did or did not, receive OAT after surgical ablation of atrial fibrillation.

In a prospective follow-up study, patients were included if surgical ablation of atrial fibrillation concomitantly with other cardiac surgery was done, between 2004 and 2018 at Aarhus University Hospital, Denmark. LEE011 After 12 months, OAT was discontinued if (a) sinus rhythm was documented by electrocardiogram, (b) atrial fibrillation was absent on 5-day Holter monitoring, (c) CHADS
score ≤2, and (d) no other indications for OAT were present. Follow-up was ended in April 2019.

A total of 560 patients underwent surgical ablation of which 436 patients reached the baseline at 12 months; 286 patients received OAT, and 150 had OAT discontinued. Survival analysis revealed no differences between the two groups (P = .723). Mean survival time in the group receiving OAT was 5.3 ± 3.3 years, compared to 5.1 ± 3.0 years in the group where OAT was discontinued (P = .784). There was no difference in major adverse cardiac and cerebrovascular events between the two groups (P = .846).

Discontinuation of OAT is safe in patients with a CHADS
score ≤2 following successful surgical ablation and left atrial appendage occlusion. This conclusion needs to be confirmed in randomized trials.
