INTRODUCTION: Catheter directed thrombolysis (CDT) is a therapeutic option with acceptable results in patients with acute limb ischaemia (ALI) but with severe systemic or intracranial bleeding being the most significant clinical complication. The aim of the study is to collect and present direct results of CDT in patients treated for ALI. MATERIALS AND METHODS: Reports on CDT treatment in ALI until December 2016 searched in PubMed using the key words catheter direct thrombolysis, acute lower limb ischemia and any combination of these...

OBJECTIVES: Our primary aim was to investigate the association between the preoperative concentration of plasma fibrinogen and the volume of postoperative bleeding. Our secondary aim was to identify whether there is a possible correlation between the patients' different characteristics and haemostatic laboratory variables and the postoperative amount of bleeding after on-pump coronary artery bypass grafting procedures. METHODS: A total of 550 adult patients undergoing isolated coronary artery bypass grafting on cardiopulmonary bypass in our hospital were enrolled and investigated retrospectively...

CEP290 mutations cause a spectrum of ciliopathies from Leber congenital amaurosis type 10 (LCA10) to embryo-lethal Meckel syndrome (MKS). Using panel-based molecular diagnosis testing for inherited retinal diseases, we identified two individuals with some preserved vision despite biallelism for presumably truncating CEP290 mutations. The first one carried a homozygous 1 base-pair deletion in exon 17, introducing a premature termination codon (PTC) in exon 18 (c.1666del; p.Ile556Phefs*17). mRNA analysis revealed a basal exon skipping (BES) of exon 18, providing mutant cells with the ability to escape protein truncation, while disrupting the reading frame in controls...

Frog egg extracts represent a powerful approach with which to dissect molecular mechanisms of vertebrate DNA replication and repair. In the classical approach, sperm chromatin is added to a crude egg lysate to form replication-competent nuclei. We subsequently described a procedure that bypasses the requirement for nuclear assembly in DNA replication. In this method, DNA is first added to a high-speed supernatant (HSS) of egg lysate, which mimics the G1 phase of the cell cycle in that it supports replication licensing...

Hemophilia and von Willebrand disease are the most common congenital bleeding disorders. Treatment for these disorders has focused on replacement of the missing coagulation factor to prevent or treat bleeding. New technologies and insights into hemostasis have driven the development of many promising new therapies for hemophilia and von Willebrand disease. Emerging bypass agents including zymogen-like factor IXa and Xa molecules are in development and a bispecific antibody, emicizumab, demonstrated efficacy in a phase III trial in people with hemophilia A and inhibitors...

PURPOSE: This study was designed to investigate the distribution of vasa vasorum in walls of failed aorto-coronary venous grafts. METHODS: Fifty-one diseased venous grafts harvested from 39 patients underwent qualitative histological evaluation. The morphology of the grade of the pathological changes and the extent of the vascularisation were examined, and related to the length of the interval between the primary surgery and the explantation. The obtained results were placed into five groups, substantially differing one from the other in morphology and vascularisation...

BACKGROUND: In atrial fibrillation (AF) patients with coronary artery disease (CAD), anticoagulants are commonly used in combination with antiplatelet drugs. However, dual therapy can increase the risk of bleeding, and the potential therapeutic benefits must be weighed against this. Therefore, it is recommended that dual therapy is only used for a limited time, and that monotherapy with anticoagulants should start from 1 year after percutaneous coronary intervention (PCI). However, there is a lack of evidence on the use of monotherapy, in particular with direct oral anticoagulants, in this group of patients...

AIM: Very little data exist regarding the effect of cardiopulmonary bypass (CPB) on cefuroxime (CXM) pharmacokinetics in children less than one year of age. METHODS: 50 mg kg-1 CXM iv after induction were followed by 75 mg kg-1 into the CPB circuit. In 42 patients undergoing cardiac surgery 15 to 20 samples were obtained between 5 and 360 min after each dose. Total CXM concentrations were measured by high-performance liquid chromatography and a PK/PD modelling was performed...

BACKGROUND: For cardiac surgery patients who were employed prior to surgery, the return to their professional life is of special importance. In addition to medical reasons, such as pre-existing conditions, the success of the operation or postoperative course and patient-intrinsic reasons, which can be assessed with the Sense of Coherence (SOC) scale by Antonovsky, may also play a role in the question of a possible return into working life. METHODS: In this study 278 patients (invasive coronary artery bypass graft surgery and/or surgery on heart valves, age < 60 years, employed) were questioned postoperatively via post with the SOC questionnaire...

Background: The microbial production of biofuels is complicated by a tradeoff between yield and toxicity of many fuels. Efflux pumps enable bacteria to tolerate toxic substances by their removal from the cells while bypassing the periplasm. Their use for the microbial production of biofuels can help to improve cell survival, product recovery, and productivity. However, no native efflux pump is known to act on the class of short-chain alcohols, important next-generation biofuels, and it was considered unlikely that such an efflux pump exists...

BACKGROUND: Heart transplantation (HTx) remains the most effective long-term treatment for advanced heart failure. Primary graft dysfunction (PGD) continues to be a potentially life-threatening early complication. In 2014, a consensus statement released by ISHLT established diagnostic criteria for PGD. We studied the incidence of PGD across the UK. METHODS: We analysed the medical records of all adult patients who underwent heart transplantation between October 2012-October 2015 in the 6 UK heart transplant centers Preoperative donor and recipient characteristics, intraoperative details and posttransplant complications were compared between the PGD and non PGD groups using the ISHLT definition...

BACKGROUND: The incidence of metachronous esophageal squamous cell cancer (ESCC) after head and neck cancer (HNC) and in elderly patients has increased. Both elderly ESCC patients and ESCC patients after HNC surgery are at potential risk for dysphagia, and for the latter, surgery in the neck is difficult. An intrathoracic anastomosis that bypasses the cervical procedure is preferable to preserve swallowing function and reduce surgical risk. In gastrectomized patients, because the stomach cannot be used as a substitute, securing graft blood supply is critical, but microvascular anastomosis cannot be easily added in procedures for intrathoracic posterior mediastinal reconstruction...

Conventionally inseminated spermatozoa suffer a dramatic reduction in numbers during their long journey until fertilization. In addition sperm survival seems to be strongly affected by the reconstitution of the female reproductive tract in the post partum period. The purpose of this study was to develop a novel AI technique for cattle that allows the deposition of spermatozoa directly into the ampulla in the immediate vicinity of the fertilization site. This new reproductive biotechnique was investigated with focus on semen origin, sperm dosage, semen preparation and time of insemination...

Somatosensory inputs to the cortex undergo an early and a later stage of processing which are characterized by an early and a late somatosensory evoked potentials (SEP). The early response is highly representative of the stimulus characteristics whereas the late response reflects a more integrative, task specific, stage of sensory processing. We hypothesized that the later processing stage is independent of the early processing stage. We tested the prediction that a reduction of the first volley of input to the cortex should not prevent the increase of the late SEP...

Protein molecular conductance has attracted attention from researchers for the possibility of constructing innovative flexible biocompatible nanoscale electronic devices and smart hybrid materials. Due to protein complexity, most evaluations of protein conductivity are based on the simple estimation of protein's molecular orbital energy levels and spatial distributions without analysing its protein interaction with electrodes and the calculation of the rates of electron transfer (ET). In the present work, we included in our density functional theory (DFT) analysis an approach based on the non-equilibrium Green's function (NEGF) allowing for calculation from the first principles the molecular interaction with electrodes and thus the role of electrode materials, Fermi level, the thermal distribution of electronic energy levels, and the coupling efficiency between the molecule and the electrodes...

BACKGROUND: Although earlier protease inhibitors have been associated with increased risk of cardiovascular disease, whether this increased risk also applies to more contemporary protease inhibitors is unknown. We aimed to assess whether cumulative use of ritonavir-boosted atazanavir and ritonavir-boosted darunavir were associated with increased incidence of cardiovascular disease in people living with HIV. METHODS: The prospective Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) study consists of people living with HIV-1 from 11 cohorts in Australia, Europe, and the USA...

REVIEW
Gustavo S Guandalini, Sripal Bangalore
Coronary artery disease in patients with diabetes mellitus (DM) is characterized by extensive atherosclerosis, longer lesions, and diffuse distal disease. Consequently, these patients have worse outcomes after coronary revascularization, regardless of the modality used. Traditionally, coronary artery bypass grafting (CABG) has been regarded as more effective than percutaneous coronary intervention (PCI) in patients with DM, likely because of more complete revascularization and protection against disease progression in the bypass segment...

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is an appropriate treatment for select patients with peritoneal carcinomatosis. While most commonly performed through an open incision, the laparoscopic approach has been reported and offers short-term benefits. A robotic-assisted approach for carcinomatosis of gastrointestinal origin, however, has not yet been described. METHODS: We report our approach to robotic-assisted CRS-HIPEC for a patient with a perforated appendiceal mucocele...
