The PI3K/AKT/mTOR (PAM) signaling pathway is frequently mutated in prostate cancer. Specific AKT inhibitors are now in advanced clinical trials and this study investigates the effect of MK2206, a non-ATP competitive inhibitor, on the cellular metabolism in the context of prostate cancer. A significant reduction in cell motility and aerobic glycolysis was observed in prostate cancer cells with treatment. These changes were not accompanied by a reduction in the ratio of high-energy phosphates or a change in total protein levels of enzymes (e...

BACKGROUND: Perforation of the esophagus is the most severe complication of transesophageal echocardiography (TEE) and can lead to mediastinitis, pleural empyema, or peritonitis. Currently, the majority of patients receive operative treatment with only 6% treated endoscopically. We report our experience with endoscopic and conservative approaches. METHODS: We retrospectively reviewed all patients treated for esophageal perforation and included all patients with perforation caused by TEE...

BACKGROUND: Estimation of cardiac output (CO) is essential in the treatment of circulatory unstable patients. CO measured by pulmonary artery catheter thermodilution is considered the gold standard but carries a small risk of severe complications. Stroke volume and CO can be measured by transesophageal echocardiography (TEE), which is widely used during cardiac surgery. We hypothesized that Doppler-derived CO by 3-dimensional (3D) TEE would agree well with CO measured with pulmonary artery catheter thermodilution as a reference method based on accurate measurements of the cross-sectional area of the left ventricular outflow tract...

OBJECTIVES: To develop and validate a genetic tool to predict age of onset of aggressive prostate cancer (PCa) and to guide decisions of who to screen and at what age. DESIGN: Analysis of genotype, PCa status, and age to select single nucleotide polymorphisms (SNPs) associated with diagnosis. These polymorphisms were incorporated into a survival analysis to estimate their effects on age at diagnosis of aggressive PCa (that is, not eligible for surveillance according to National Comprehensive Cancer Network guidelines; any of Gleason score ≥7, stage T3-T4, PSA (prostate specific antigen) concentration ≥10 ng/L, nodal metastasis, distant metastasis)...

The dietary approaches to stop hypertension (DASH) diet could be an important population-level strategy to reduce cardiovascular disease (CVD) in the UK, but there is little UK-based evidence on this diet pattern in relation to CVD risk. We tested whether dietary accordance with DASH was associated with risk of CVD in a population-based sample of 23,655 UK adults. This prospective analysis of the EPIC-Norfolk cohort study analysed dietary intake (assessed using a validated food frequency questionnaire) to measure accordance with DASH, based on intakes of eight food groups and nutrients, ranking the sample into quintiles...

Extensive left main (LM) coronary artery thrombus is a rare and life-threatening angiographic finding with usual dramatic clinical presentation including hemodynamic instability and sudden cardiac death. The proper management of a big LM thrombus extending into aorta remains a challenging issue with no clear guidelines. In the following case report we present a 45-year-old patient with no apparent risk factors for coronary artery disease who presented with acute infero-lateral ST-elevation myocardial infarction (STEMI)...

Hand grip strength is a widely used proxy of muscular fitness, a marker of frailty, and predictor of a range of morbidities and all-cause mortality. To investigate the genetic determinants of variation in grip strength, we perform a large-scale genetic discovery analysis in a combined sample of 195,180 individuals and identify 16 loci associated with grip strength (P<5 × 10-8) in combined analyses. A number of these loci contain genes implicated in structure and function of skeletal muscle fibres (ACTG1), neuronal maintenance and signal transduction (PEX14, TGFA, SYT1), or monogenic syndromes with involvement of psychomotor impairment (PEX14, LRPPRC and KANSL1)...

BACKGROUND: Thromboembolic events (TEEs) represent a significant treatment and disease complication for cancer patients. In the present study we assessed the incidence of TEEs in patients receiving preoperative chemotherapy for esophagogastric adenocarcinoma. The risk factors for TEE development and their impact on prognosis were further analyzed. MATERIAL AND METHODS: Data from 590 patients with esophagogastric adenocarcinoma, who received preoperative epirubicin-cisplatin with capecitabine (ECX) or 5-fluorouracil (ECF) between 2009 and 2016 in three UK hospitals were retrospectively collected...

Hepatocellular carcinoma (HCC) is not uncommon neoplasm, and its occurrences with coronary artery disease (CAD) is more confronted by cardiac surgeon today. In most cases, when the HCC is detected, it has invaded to regional or distant sites. The most frequent location of HCC metastasis includes pulmonary system, musculoskeletal, lymphatic system, and central nervous system. Indeed, intra-atrial metastasis is a rare phenomenon and associated with poor outcome. We report a case of CAD with known HCC that referred for CABG before scheduling for hepatic tumor management...

PURPOSE: We sought to compare force-velocity relationships developed from unloaded sprinting acceleration to that compiled from multiple sled-resisted sprints. METHODS: Twenty-seven mixed-code athletes performed six to seven maximal sprints, unloaded and towing a sled (20-120% of body-mass), while measured using a sports radar. Two methods were used to draw force-velocity relationships for each athlete: A multiple trial method compiling kinetic data using pre-determined friction coefficients and aerodynamic drag at maximum velocity from each sprint; and a validated single trial method plotting external force due to acceleration and aerodynamic drag and velocity throughout an acceleration phase of an unloaded sprint (only)...

Src family kinases (SFKs) coordinate the initiating and propagating activation signals in platelets, however it remains unclear how they are regulated. Here we show that ablation of C-terminal Src kinase (Csk) and receptor-like protein tyrosine-phosphatase CD148 in mice results in a dramatic increase in platelet SFK activity, demonstrating that these proteins are essential regulators of platelet reactivity. Paradoxically, Csk/CD148-deficient mice exhibit reduced in vivo and ex vivo thrombus formation and increased bleeding following injury, rather than a prothrombotic phenotype...

REVIEW
Ellie Rad, James T Murray, Andrew R Tee
Throughout the years, research into signalling pathways involved in cancer progression has led to many discoveries of which mechanistic target of rapamycin (mTOR) is a key player. mTOR is a master regulator of cell growth control. mTOR is historically known to promote cell growth by enhancing the efficiency of protein translation. Research in the last decade has revealed that mTOR's role in promoting cell growth is much more multifaceted. While mTOR is necessary for normal human physiology, cancer cells take advantage of mTOR signalling to drive their neoplastic growth and progression...

Routine testing for inherited and acquired thrombophilia defects is frequently performed in pediatric patients with thromboembolic events (TEEs). No consensus guidelines exist regarding the timing of testing or the type of patients to be tested. The primary objective of our study, therefore, was to determine whether thrombophilia testing during the acute TEE setting affected clinical management in pediatric patients. A secondary aim included estimation of potential harm from thrombophilia testing. We retrospectively reviewed data on all pediatric patients diagnosed with a TEE during a 1-year period...
