BACKGROUND: A key component of modern analgesics is the use of multimodal opioid-sparing analgesia (MOSA). In the past, our analgesic regime after autologous breast reconstruction (ABR) included either NSAID or a selective cyclooxygenase-2 (COX-2) inhibitor. COX-2 inhibitors are superior to NSAIDs because of the well-known side effects of NSAID treatment (bleeding/gastrointestinal ulcers). However, COX-2 inhibitors have been suggested to increase flap failure rates. We report our experience in using COX-2 inhibitors as part of our post-operative MOSA after ABR using free flaps...

Cardio-Oncology is the care of cancer patients with cardiovascular disease, overt or occult, already established or acquired during treatment. Cancer patients can present with a variety of cardiovascular problems not all of which are directly related to cancer therapy (medications or radiotherapy). The cardiovascular problems of oncology patients can range from ischaemia to arrhythmias and can also include valve problems and heart failure. As such, within cardiology, teamwork is required with members of different cardiology subspecialties...

The number of permanent colostomies carried out in the United Kingdom is approximately 6400 per year1. Stomal prolapse is a known complication of colostomy formation. We presented the first case of small bowel herniation into a healthy stomal prolapse with subsequent ischaemia of the herniated bowel in a 102-year-old patient. This rare sequela of a relatively common stomal complication highlights an important consideration when faced with a large prolapse presenting acutely. It also raises an important discussion point for the management of our ever-ageing patient population...

Orbital inflammatory disease and secondary optic neuropathy is a rare but devastating complication of long-term intranasal cocaine abuse. We describe 2 patients with a history of intranasal cocaine consumption who presented with subacute onset of unilateral vision loss from optic neuropathy and limitation of abduction in the affected eye. Magnetic resonance imaging findings included an orbital mass in combination with absent nasal septum and partial destruction of the paranasal sinuses. Biopsies and histopathologic examination of the nasal cavity and the orbital mass revealed chronic inflammation...

Background For secondary prevention of acute coronary syndrome, guidelines recommend dual antiplatelet therapy (DAPT) with acetylsalicylic acid and a P2Y12 receptor antagonist such as clopidogrel, prasugrel or ticagrelor for a period of 12 months. Often, uncertainty exists with respect to surgical or diagnostic procedures in these high-risk patients: can the DAPT be continued without interruption? If not, what is the recommended withdrawal strategy? What should be considered for the perioperative management? Methods An interdisciplinary group of experienced experts in the fields of cardiology, cardiac surgery, gastroenterology, anaesthesiology, intensive care and haemostaseology developed recommendations relevant to daily clinical practice based on the current scientific evidence...

OBJECTIVES: Scutellarin (SCU) is a traditional Chinese medicine used for the treatment of ischaemic cerebrovascular disease, but its clinic applications have been limited due to its poor water solubility, poor bioavailability and short half-life. In comparison with the conventional oral and intravenous administration, nasal administration may help targeting the drug more directly to brain. Thus, we proposed to employ a novel SCU-loaded HP-β-CD/chitosan nanoparticles (CD/CS-SCU-NPs) to deliver SCU to brain through the nasal route...

The creatine kinase (CK) phosphagen system is fundamental to cellular energy homeostasis. Cardiomyocytes express three CK isoforms, namely the mitochondrial sarcomeric CKMT2 and the cytoplasmic CKM and CKB. We hypothesized that augmenting CK in vitro would preserve cell viability and function and sought to determine efficacy of the various isoforms. The open reading frame of each isoform was cloned into pcDNA3.1, followed by transfection and stable selection in human embryonic kidney cells (HEK293). CKMT2- CKM- and CKB-HEK293 cells had increased protein and total CK activity compared to non-transfected cells...

OBJECTIVE: Cases of giant renal angiomyolipoma (>9cm) are a therapeutic challenge due to their low frequency and large size. The treatment objective for patients with renal angiomyolipoma should be complete tumour extirpation, with a nephron-sparing surgical technique, without complications and using a minimally invasive approach. MATERIAL AND METHODS: We present 3 cases of giant angiomyolipoma (10 12 and 14cm) treated with a combined approach: superselective embolisation and subsequent laparoscopic partial nephrectomy, in 3 separate hospitals...

To preserve the disequilibrium between ATP and ADP necessary to drive cellular metabolism, enzymatic pathways rapidly convert ADP to adenosine and the downstream purines inosine and hypoxanthine. During ischaemia, these same pathways result in the production of purines. We performed a prospective observational study to test whether purine levels in arterial blood might correlate with brain ischaemia. We made real-time perioperative measurements, via microelectrode biosensors, of the purine levels in untreated arterial blood from 18 patients undergoing regional anaesthetic carotid endarterectomy...

STUDY OBJECTIVE: There are two windows of protection for remote ischemic preconditioning (RIPC), an early (ERIPC) and a late-phase (LRIPC). While ERIPC has been well studied, works on LRIPC are relatively scarce, especially for the kidneys. We aimed to compare the effects of early-phase versus late-phase RIPC in patients with laparoscopic partial nephrectomy (LPN). DESIGN: A randomized controlled study SETTING: The Second Affiliated Hospital of Anhui Medical University, 1 May 2012 to 30 October 2013 PATIENTS: Sixty-five ASA 1 to 2 patients scheduled for LPN were located randomly to ERIPC group, LRIPC group and CON group (control)...

OBJECTIVES: In stable coronary artery disease (CAD), coronary revascularisation may reduce mortality of patients with a certain amount of left ventricular myocardial ischaemia. However, revascularisation does not always follow the guidance suggested by ischaemia testing. We compared outcomes in patients without ischaemia who had either revascularisation or medical treatment. DESIGN AND POPULATION: Based on registries, 1327 consecutive patients with normal myocardial perfusion scintigraphy (MPS) and 278 with fixed perfusion defects were followed for a median of 6...

Ischaemic heart disease remains the leading cause of morbidity and mortality in the Western world. Artesunate is the WHO-recommended drug of choice for complicated malaria (with organ failure). The administration of high doses of artesunate is safe in healthy volunteers (up to 8 mg/kg i.v) and patients with severe malaria (2.4 mg/kg i.v). We investigated the effects of artesunate (1 mg/kg) or its active metabolite dihydroartemisinin (DHA; 0.1 mg/kg) in a model of transient myocardial ischaemia/reperfusion (I/R) and evaluated the mechanism of action of the observed cardioprotective effects of artesunate and DHA...

Recently, the dipeptidyl peptidase-4 (DPP-4) inhibitor sitagliptin, a major anti-hyperglycaemic agent, has received substantial attention as a therapeutic target for cardiovascular diseases via enhancing the number of circulating endothelial progenitor cells (EPCs). However, the direct effects of sitagliptin on EPC function remain elusive. In this study, we evaluated the proangiogenic effects of sitagliptin on a diabetic hind limb ischaemia (HLI) model in vivo and on EPC culture in vitro. Treatment of db/db mice with sitagliptin (Januvia) after HLI surgery efficiently enhanced ischaemic angiogenesis and blood perfusion, which was accompanied by significant increases in circulating EPC numbers...

To evaluate if early unclamping (EUC) of the renal pedicle compromises perioperative outcomes in minimally invasive partial nephrectomy (PN). The cohort study includes all robot-assisted PN performed between September 2012 and September 2015 by a single surgeon at the Lister Hospital, Stevenage, UK. The systematic review and meta-analysis was performed according to the PRISMA guidelines identifying studies comparing EUC and standard unclamping (SUC) in either laparoscopic or robot-assisted PN. The Lister cohort prospectively reported 84 cases of robot-assisted PN (SUC = 22, EUC = 62) with a mean age of 58 years (SD = 11)...

Most in vivo models of ischaemic stroke target the middle cerebral artery and a spectrum of stroke severities, from mild to substantial, can be achieved. This review describes opportunities to improve the in vivo modelling of ischaemic stroke and animal welfare. It provides a number of recommendations to minimise the level of severity in the most common rodent models of middle cerebral artery occlusion, while sustaining or improving the scientific outcomes. The recommendations cover basic requirements pre-surgery, selecting the most appropriate anaesthetic and analgesic regimen, as well as intraoperative and post-operative care...

Histone deacetylase (HDAC) inhibitors prevent neural cell death in in vivo models of cerebral ischaemia, brain injury and neurodegenerative disease. One mechanism by which HDAC inhibitors may do this is by suppressing the excessive inflammatory response of chronically activated microglia. However, the molecular mechanisms underlying this anti-inflammatory effect and the specific HDAC responsible are not fully understood. Recent data from in vivo rodent studies has shown that inhibition of class I HDACs suppresses neuroinflammation and is neuroprotective...

OBJECTIVE: Patients with critical limb ischaemia (CLI) lack sufficient blood flow in to the limb, which leads to difficulties in the normal wound healing process. Therefore, maggot debridement therapy (MDT) has not generally been recommended for CLI patients. We evaluated the effectiveness of wound bed preparation by MDT in CLI patients who had undergone mid-foot amputation. METHODS: Patients who underwent mid-foot amputation after angioplasty between April 2014 and October 2016 were retrospectively investigated by classifying them into an MDT group or a conventional treatment group...
