Summary: This study aimed to investigate the occurrence rate of sudden cardiac death (SCD), arrhythmia, and conduction defects in SSc patients. The findings showed that the annual incidence of SCD in SSc patients ranged from 1.0% to 3.3%, which is at least 10 times higher than the general population. Additionally, arrhythmias were common even in SSc patients without known or suspected SSc-associated heart involvement.

Summary: This study found a significant association between monocyte-lymphocyte ratio (MLR) and increased risk of new-onset cardiac conduction block (CCB). Assessing MLR may have clinical relevance for predicting CCB risk and providing insights for preventive strategies and patient management.

Summary: The study of the inactivation mechanism of hERG is crucial due to its association with cardiac arrhythmias. Two models, namely, the closure of the selectivity filter and the widening of the extracellular portion of the selectivity filter, have been proposed to describe C-type inactivation in potassium channels. Molecular dynamics simulations revealed that the extracellular entrance of hERG widens during inactivation, supporting the hypothesis of widening of the extracellular entrance rather than closure of the selectivity filter.

Summary: Fast C-type inactivation confers distinctive functional properties to the hERG potassium channel, but its mechanism and association with cardiac arrythmias are of paramount importance. Two models have been proposed for C-type inactivation in K+ channels, and this study used molecular dynamics simulations to investigate the mechanism in hERG. The findings suggest that C-type inactivation in hERG involves a widening of the extracellular entrance of the channel rather than a closure of the selectivity filter.

Summary: In this study, machine learning is used to accurately predict the arrhythmic risk caused by cardiac fibrosis. The research explores the initiation sites of re-entry activation patterns and their sensitivity to activation sequence, as well as the range of structural information required to predict re-entry initiation.

Summary: In the past 20 years, genetic variants in SCN5A encoding the cardiac voltage-gated sodium channel Na(v)1.5 have been associated with a range of inherited cardiac arrhythmias. Loss-of-function variants have been linked to sick sinus syndrome, atrial stand still, atrial fibrillation, impaired pulse generation, conduction defects, the Brugada syndrome, and sudden cardiac death. Gain-of-function variants have been associated with Long QT syndrome type 3, Torsade de Pointes ventricular tachycardia and SCD, as well as the Multifocal Ectopic Purkinje-related Premature Contractions (MEPPC) syndrome. MEPPC is a rare condition characterized by a high burden of premature contractions and dilation of the heart muscle. The link between SCN5A variants, MEPPC and DCM is not yet fully understood.

Summary: In a retrospective cross-sectional study comparing cardiac conduction in patients with primary hyperparathyroidism (PHPT) or thyroid disease (TD), it was found that PHPT patients had shorter QTc intervals compared to TD controls. However, there was no significant difference in the prevalence of arrhythmia between the two groups.

Summary: Transcatheter aortic valve implantation (TAVI) has become a widely accepted treatment method for aortic stenosis in patients who are at high surgical risk or disqualified from surgery. However, TAVI is associated with a high incidence of conduction abnormalities, such as heart block, which may require permanent pacemaker implantation. Understanding the risk factors for these complications and providing optimal care is crucial for improving patient outcomes.

Summary: This study used genetic evidence to analyze the relationship between leukocyte counts and the risk of different types of arrhythmia. The results showed that an increase in lymphocyte count is associated with a higher risk of atrioventricular block, but there is uncertain evidence on the relationship between neutrophil and basophil counts and the risk of atrial fibrillation.

Summary: This study aimed to evaluate the effects of transcutaneous medium-frequency alternating electrical current stimulation on sensory perception and force production in the index and middle finger. The results showed that stimulation at 2 kHz and 10 kHz could inhibit tactile sensory nerve activity in the fingers, while motor nerve activity was not significantly affected.

Summary: This review discusses the available analgesic options for acute pancreatitis and emphasizes the evidence specific to this condition. Nonsteroidal anti-inflammatory drugs and paracetamol are effective alternatives to opioids for pain relief in acute pancreatitis. Epidural analgesia provides optimal pain relief in the first 24 hours after onset, and experimental analgesics and acupuncture may potentially reduce opioid use. Tailoring treatment to the individual patient, assessing pain intensity and pancreatitis severity, and using opioid sparing strategies whenever possible are important principles in pain management for acute pancreatitis.

Summary: Acute Mesenteric Ischaemic (AMI) is a rare and serious condition, and current treatments have limitations. This systematic review of experimental studies suggests that intraluminal oxygen delivery may be an effective treatment for AMI, but further research is needed to determine the optimal timing and formulation before clinical translation.

Summary: Acute on chronic pancreatitis (ACP) is a common condition, but there are significant gaps in our knowledge about it. Through a systematic review and expert consensus, a new definition of ACP was reached. Despite the poor evidence base, this position statement provides a foundation for the management of ACP.

Summary: This study aimed to optimize the technique for measuring intra-bladder pressure in patients with predicted severe acute pancreatitis. The results showed that measuring intra-bladder pressure at the iliac crest with a head of bed elevation of 15 degrees and instilling 25 mL of normal saline can be appropriate for monitoring intra-abdominal pressure in predicted severe acute pancreatitis patients. A bed elevation of 30 degrees significantly increased intra-bladder pressure.

Summary: This systematic review and meta-analysis found that epidural anesthesia (EA) is safe and effective in managing pain in acute pancreatitis (AP). EA can reduce pain severity, improve pancreatic perfusion, and decrease mortality in AP patients. The use of EA is associated with lower need for ventilatory support.

Summary: Pancreatic ductal adenocarcinoma is a debilitating disease with no effective treatments. Trichoderin A, a natural product, shows promise as an anticancer agent. It selectively kills pancreatic cancer cells under glucose deprivation, which is significant given the nutrient-deprived nature of the disease.
