Isolated myocardial involvement in tuberculosis is exceedingly rare but there are reports it can present with sudden cardiac death, atrioventricular block, ventricular arrhythmias or congestive cardiac failure. We report the case of a 33 year-old male, of South Asian descent, who presented with chest pain, shortness of breath and an abnormal ECG. The patient had no significant past medical history and coronary angiogram showed no evidence of coronary artery disease. Of note the patient had recently been discharged from a local district hospital with an episode of myocarditis...

Cardiac arrest represents a leading cause of mortality and morbidity in developed countries. Extracorporeal cardiopulmonary resuscitation (ECPR) increases the chances for a beneficial outcome in victims of refractory cardiac arrest. However, ECPR and post-cardiac arrest care are affected by high mortality rates due to multi-organ failure syndrome, which is closely related to microcirculatory disorders. Therefore, microcirculation represents a key target for therapeutic interventions in post-cardiac arrest patients...

Therapeutic hypothermia (TH) is a neuroprotective treatment post-cardiac arrest but is grossly underutilized. After TH induction, traditional biomarkers and parameters can no long predict clinical outcome due to a lack of understanding of hypothermic response. Innovative approaches to better understand the clinical effect of TH will help to prognosticate outcome and expand beneficial population. Protein glycosylation is an important extracellular post-translational modification, regulating various extracellular signaling pathways...

Sonic hedgehog (SHH) is an essential morphogenetic signal dictating cell fate decisions in several developing organs in mammals. In vitro data suggest that SHH is required to specify LHX3+/LHX4+ Rathke's pouch (RP) progenitor identity. However, in vivo studies have failed to reveal such a function, supporting instead, a critical role for SHH in promoting proliferation of these RP progenitors and for differentiation of pituitary cell types. Here, we have used a genetic approach to demonstrate that activation of the SHH pathway is necessary to induce LHX3+/LHX4+ RP identity in mouse embryos...

INTRODUCTION: In this study, we retrospectively reviewed the patients' outcomes after cardiac arrest based on age in one center, to determine whether geriatric patients had worse outcomes. METHODS: This was a single-center, retrospective cohort study. The patients admitted to the intensive care unit on successful resuscitation after OHCA were retrospectively identified and evaluated. RESULTS: This was a retrospective cohort study of patients over 18years of-age with return of spontaneous circulation (ROSC) (>24h) after cardiac arrest who were admitted to the emergency intensive care unit (EICU) and received post-cardiac arrest care between March 2007 and December 2013...

Kidneys from uncontrolled donors after cardiac arrest (uDCD) suffer from a period of warm ischemia between cardiac arrest and cold flushing. Aim of the study was to evaluate renal outcomes of uDCD kidneys selected on the basis of renal Resistance Index (RI) and its influence on graft function and survival. The study included 44 kidneys procured from 26 uDCD starting 1.1.2006 until 31.12.2013. The donors (Maastricht category II) underwent cardiopulmonary resuscitation by assisted ventilation and chest compression; the organs were preserved with "in situ" cold perfusion or a normothermic regional perfusion...

INTRODUCTION: Despite decades of research into the prognostic significance of post anoxic myoclonic status (MS), no consistent definition has been used to describe its clinical appearance. We set out to characterize the clinical features of MS and hypothesized that there are distinct clinical subtypes that may have prognostic implications. METHODS: Video EEG reports from 2008 to 2016 were searched to identify adult patients with post anoxic MS defined as persistent myoclonus for >30minutes beginning within 3days of cardiac arrest in a comatose patient...

Since its discovery more than three decades ago, tumor suppressor p53 has been shown to play pivotal roles in both maintaining genomic integrity and tumor suppression. p53 functions as a transcription factor responding to a multitude of cellular stressors, regulating the transcription of many genes involved in cell-cycle arrest, senescence, autophagy, and apoptosis. Extensive work has revealed that p53 is one of the most commonly mutated tumor suppressor genes. The last three decades have demonstrated that p53 activity is controlled through transcriptional regulation and posttranslational modifications...

Sudden unexpected death in epilepsy (SUDEP) is the leading cause of death in refractory epilepsy patients. While specific mechanisms underlying SUDEP are not well understood, evidence suggests most SUDEP occurs due to seizure-induced respiratory arrest. SUDEP also tends to happen at night. While this may be due to circumstances humans find themselves in at night, such as being alone without supervision or sleeping prone, or due to independent influences of sleep state, there are a number of reasons why the night (i...

Survival from out-of-hospital cardiac arrest in Denmark has increased significantly since 2001, and important improvements have been made in the post-resuscitation care. The aim of this article is to summarize the most recent international guidelines for post-resuscitation care in a Danish perspective. The main aspects concern securing haemodynamic and respiratory functions and performing urgent coronary catheterization and targeted temperature management in selected patients. In prognostication a multi-modal approach should be applied...

Mammalian hibernation is a state of dormancy that is used by some animals to survive through the unfavorable conditions of winter, and is characterized by coordinated suppression of basal metabolism that is supported by global inhibition of energy/ATP-consuming processes. In this study, we examine the regulation of the anti-proliferatory TGF-β/Smad transcription factor signaling pathway in the liver tissue of the hibernating 13-lined ground squirrel Ictidomys tridecemlineatus. The TGF-β/Smad signaling pathway is known to mediate cell cycle arrest through induction of cell cycle dependent kinase inhibitors, and more recently, has been shown to regulate a wide range of cellular processes via its control of microRNA biosynthesis...

Maintaining the integrity of genetic information across generations is essential for both cell survival and reproduction, and requires the timely repair of DNA damage. Histone-modifying enzymes play a central role in the DNA repair process through the deposition and removal of post-translational modifications on the histone tails. Specific histone modification act in the DNA repair process through the recruitment of proteins and complexes with specific enzymatic activities, or by altering the chromatin state at the site of DNA lesions...

Pectoral muscle (PM) comprises an important component of overall meat mass in ducks. However, PM has shown arrested or even reduced growth during late embryonic development, and the molecular mechanisms underlying PM growth during the late embryonic to neonatal period in ducks have not been addressed. In this study, we characterized potential candidate genes and signaling pathways related to PM development using RNA sequencing of PM samples selected at embryonic days (E) 21 and 27 and 5 days post-hatch (dph) in two duck breeds (Gaoyou and Jinding ducks)...

GADD45A (growth arrest and DNA damage inducible alpha), a stress response gene induced by genotoxic and nongenotoxic stresses, is implicated in various key processes, including the control of cell cycle checkpoints and DNA repair. The expression of GADD45A is directly regulated by numerous transcription factors, with p53 being the most representative. Moreover, post-transcriptional regulation also plays a role in GADD45A expression. However, little is known about the regulatory effects of microRNAs (miRNAs) on GADD45A expression...

OBJECTIVES: Factors associated with performing urgent coronary angiography (UCA) in patients with out-of-hospital cardiac arrest (OHCA) were identified. BACKGROUND: Current guidelines for resuscitated OHCA patients recommend UCA if there is ST-elevation on post-arrest electrocardiogram or high suspicion of acute myocardial infarction. Some have advocated for UCA in all OHCA regardless of suspected etiology. The reasons for variations in performing UCA are not well understood...

Some studies conclude that mild hypothermia causes platelet dysfunction leading to an increased bleeding risk, whereas others state that platelet aggregation is enhanced during mild hypothermia. Therefore, the aim of this study was to clarify whether standard or prolonged duration of targeted temperature management affected platelet aggregation. We randomised 82 comatose patients resuscitated after out-of-hospital cardiac arrest to either 24 hours (standard group) or 48 hours (prolonged group) of targeted temperature management at 33±1°C...
