Recovery pathway

Tony G Walsh, Alastair W Poole
Our understanding of platelet function has traditionally focused on their roles in physiological hemostasis and pathological thrombosis, the latter being causative of vessel occlusion and subsequent ischemic damage to various tissues. In particular, numerous in vivo studies have implicated causative roles for platelets in the pathogenesis of ischemia-reperfusion (I/R) injury to the myocardium. However, platelets clearly have more complex pathophysiological roles particularly as a result of the heterogeneous nature of biologically active cargo secreted from their granules, or contained within released microparticles or exosomes...

Background -Angiogenesis is integral for embryogenesis, and targeting angiogenesis improves the outcome of many pathological conditions in patients. TBX20 is a crucial transcription factor for embryonic development, and its deficiency is associated with congenital heart disease. However, the role of TBX20 in angiogenesis has not been described. Methods -Loss- and gain-of-function approaches were used to explore the role of TBX20 in angiogenesis both in vitro and in vivo Angiogenesis gene array was used to identify key downstream targets of TBX20...

Drug-induced liver injury (DILI) remains a clinical challenge due to the poorly predictable outcomes. Accordingly, considerable efforts have been devoted to unravel the risk factors responsible for DILI worsening toward acute liver failure (ALF), liver transplantation (LT), and/or death. From a pathogenic point of view, exhaustion of drug metabolizing pathways, cell death mechanisms, activation of local immune cells, such as Kupffer cells, and recruitment of inflammatory leukocytes including monocytes and lymphocytes are key drivers of DILI progression...

OBJECTIVES: To determine whether an enhance recovery protocol for radical cystectomy patient affected the length of stay or the number and type of readmissions that occurred after hospital discharge. METHODS: We prospectively assessed 152 cystectomy patients after initiation of the pathway. These patients were compared to the previous 147 patient operated on prior to the pathway initiation. Eligible patients were those undergoing radical cystectomy with any diversion at our institution...

BACKGROUND: The WHO includes osteoarthritis as a disease of priority, owing to its significant impact on quality of life, and globally increasing prevalence. Hospital budgets are under pressure to ration knee replacements and shorten inpatient stays. Prolonged tourniquet application has been hypothesised to extend recovery through pain and reduced mobility. PATIENTS AND METHODS: A total of 123 elective total knee replacements meeting inclusion criteria took place from July 2015 to October 2017 at the Royal Free Hospital...

Introduction: Supplementary motor area (SMA) syndrome is a constellation of temporary symptoms that may occur following tumors of the frontal lobe. Affected patients develop akinesia and mutism but often recover within weeks to months. With our own case examples and with correlations to fiber tracking validated by gross anatomical dissection as ground truth, we describe a white matter pathway through which recovery may occur. Methods: Diffusion spectrum imaging from the Human Connectome Project was used for tractography analysis...

Background: Herbal supplements are commonly used, however, their side-effect profiles are poorly understood and not subject to the same scrutiny as prescribed medications. Some herbal supplements such as St Johns' Wort are accepted to interfere with clotting pathways, however others, including Red Clover have theoretical bleeding risks based on coumarin content with very little underlying evidence. Case Description: This case reports a 65-year-old woman who suffered a spontaneous acute-on-chronic subdural hemorrhage with a significant postoperative re-hemorrhage...

Cardiac energy demands during early embryonic periods are sufficiently met through glycolysis, but as development proceeds, oxidative phosphorylation in mitochondria becomes increasingly vital. Adrenergic hormones are known to stimulate metabolism in adult mammals and are essential for embryonic development, but relatively little is known about their effects on metabolism in the embryonic heart.  Here, we show that embryos lacking adrenergic stimulation have approximately 10-fold less cardiac ATP compared to littermate controls...

INTRODUCTION: Hip and knee replacement represents a significant burden to the UK healthcare system. 'Enhanced recovery' pathways have been introduced in the National Health Service (NHS) for patients undergoing hip and knee replacement, with the aim of improving outcomes and timely recovery after surgery. To support policymaking, there is a need to evaluate the cost-effectiveness of enhanced recovery pathways across jurisdictions. Our aim is to systematically summarise the published cost-effectiveness evidence on enhanced recovery in hip and knee replacement, both as a whole and for each of the various components of enhanced recovery pathways...

In this issue of Acta Physiologica, Ansar et al. study the role of MAPK in ischemic stroke1 . The mitogen activated protein kinase (MAPK) pathways have long been recognized as major common mediators of stimuli that lead to cell growth and proliferation in numerous cell types. MAPK pathways also influence diverse cell processes such as differentiation, motility, and survival, often through activation of secondary downstream kinases (MAPKAP kinases)2 .

By altering the intrinsic metabolism of the cell, including the upregulation of regeneration-associated genes (RAGs) and the production of structural proteins for axonal outgrowth, the conditioning lesion sets up an environment highly conducive to regeneration. In this review, we assess forty years of research to provide a comprehensive overview of the conditioning lesion literature, directed at: a) discussing the mechanisms of, and barriers to nerve regeneration that can be mitigated by the conditioning lesion; b) describing the cellular and molecular pathways implicated in the conditioning lesion effect; and c) deliberating on how these insights might be applied clinically...

The process characteristics of microwave assisted hydrothermal carbonization of cellulose was investigated and a first order kinetics model based on carbon concentration was developed. Chemical properties analysis showed that comparing to conventional hydrothermal carbonization, hydrochar with comparable energy properties can be obtained with 5-10 times decrease in reaction time with assistance of microwave heating. Results from kinetics study was in great agreement with experimental analysis, that they both illustrated the predominant mechanism of the reaction depend on variations in the reaction rates of two co-existent pathways...

SUMOylation and deSUMOylation, a dynamic process, is proved to be involved in various fibrotic diseases. Here, we found SENP2, one of deSUMOylation protease family member, was decreased in CCl4 -induced mice fibrotic liver tissues, primary HSCs and restored after spontaneously recovery. In addition, HSC-T6 cells with TGF-β1 treatment resulted in a significant reduction of SENP2. Ectopic expression of SENP2 hindered cells activation and proliferation induced by TGF-β1 while knockdown of SENP2 showed an opposite effect...

Pericytes have long been regarded merely to maintain structural and functional integrity of blood-brain barrier (BBB). Nevertheless, it has also been identified as a component of scar-forming stromal cells after spinal cord injury (SCI). In process of enlargement of spinal cavity after SCI, the number of pericytes increased and outnumbered astrocytes. However, the mechanism of proliferation of pericytes remains unclear. Sphingosine-1-phosphate (S1P) has been reported to play important roles in the formation of glia scar, but previous studies had paid more attention to the astrocytes...

Although a plethora of signaling pathways are known to drive the activation of hepatic stellate cells in liver fibrosis, the involvement of connexin-based communication in this process remains elusive. Connexin43 expression is enhanced in activated hepatic stellate cells and constitutes the molecular building stone of hemichannels and gap junctions. While gap junctions support intercellular communication, and hence the maintenance of liver homeostasis, hemichannels provide a circuit for extracellular communication and are typically opened by pathological stimuli, such as oxidative stress and inflammation...
