Acute kidney injury (AKI) is an important complication of both diagnostic cardiac catheterization and percutaneous coronary intervention (PCI). A large body of evidence supports that AKI is related to volume of contrast used. Despite several measures are available to reduce the impact of contrast media on AKI, its incidence remains significant as other mechanisms of renal damage are involved. A new paradigm is established according to which bleeding prevention is at least as important as preventing recurrent ischemic events in the management of patients with acute coronary syndromes (ACS) undergoing an invasive approach. Periprocedural bleeding, which is consistently reduced by radial approach, is emerging as a risk factor for the development of AKI. Therefore, the role of vascular access as a measure to prevent AKI needs to be systematically assessed in randomized studies. To date, no prospective comparison on renal outcomes has been carried out in randomized trials between radial and femoral approach. The Minimizing Adverse hemorrhagic events by TRansradial access site and systemic Implementation of AngioX (MATRIX) trial (ClinicalTrials.gov identifier: NCT01433627) has been designed to test whether to minimize bleeding events by using radial access and bivalirudin, across the whole spectrum of patients with ACS undergoing PCI, will result in improved outcomes with respect to both ischemic and bleeding complications. The AKI-MATRIX sub-study will provide a unique opportunity to assess whether the advantages of radial approach may even contribute to the reduction of the risk of AKI in patients with ACS. © 2015 Wiley Periodicals, Inc.

Objectives To describe the clinical characteristics and in-hospital outcomes of older adults with tako-tsubo cardiomyopathy (TTC). Design Partially retrospective, partially prospective observational study. Setting Eleven Italian referral cardiac centers included in the Tako-tsubo Italian Network. Participants One hundred ninety consecutive individuals with TTC (92.1% female, mean age 66) were divided into three groups according to age (<65, n = 78; 65-74, n = 61; ≥75, n = 51). Measurements Clinical findings and in-hospital outcomes were evaluated in each group. Results Participants aged 65 and older had a greater prevalence of hypertension (P =.001) and a lower glomerular filtration rate (P <.001), and those aged 65 to 74 had a greater prevalence of psychiatric disorders (P =.01), ST-segment elevation on admission (P =.01) and a cerebrovascular disease (P =.003) than those younger than 65. Despite similar left ventricular ejection fraction (LVEF) on admission (P =.26), the oldest group had a lower LVEF at discharge (P =.03). Inotropic agents were used more frequently in older adults (P =.03). In-hospital composite adverse events (all-cause death, acute heart failure, life-threatening arrhythmias, stroke, and cardiogenic shock; P =.03) and overall complications (P =.004) were more common in participants aged 75 and older. Overall in-hospital mortality was low (2.8%) but was more prevalent in participants aged 75 and older (6.3%). On multivariate analysis, age of 75 and older (hazard ratio (HR) = 2.45, 95% confidence interval (CI) = 1.28-5.82, P =.04) and LVEF on admission (HR = 0.874, 95% CI = 0.81-0.95, P <.001) were the only independent predictors of in-hospital adverse events. Conclusion The clinical profile of participants aged 75 and older with TTC was different from that of those younger than 75 with TTC, and they had a higher in-hospital complication rate. © 2011, The American Geriatrics Society.

When linking in time electrical stimulation of the peripheral nerve with transcranial magnetic stimulation (TMS), the excitability of the motor cortex can be modulated to evoke clear inhibition, as reflected by the amplitude decrement in the motor-evoked potentials (MEPs). This specific property, designated short-latency afferent inhibition (SAI), occurs when the nerve-TMS interstimulus interval (ISI) is approximately 25 ms and is considered to be a corticothalamic phenomenon. The aim of the present study was to use the electroencephalographic (EEG) responses to navigated-TMS coregistration to better characterize the neuronal circuits underlying SAI. The present experimental set included magnetic resonance imaging (MRI)-navigated TMS and 60- channel TMS-compatible EEG devices. TMS-evoked EEG responses and MEPs were analyzed in eight healthy volunteers; ISIs between median nerve and cortical stimulation were determined relative to the latency of the individual N20 component of the somatosensoryevoked potential (SEP) obtained after stimulation of the median nerve. ISIs from the latency of the N20 plus 3 ms and N20 plus 10 ms were investigated. In all experimental conditions, TMS-evoked EEG responses were characterized by a sequence of negative deflections peaking at approximately 7, 44, and 100 ms alternating with positive peaks at approximately 30, 60, and 180 ms post-TMS. Moreover, ISI N20+3 ms modulated both EEG-evoked activity and MEPs. In particular, it inhibited MEP amplitudes, attenuated cortical P60 and N100 responses, and induced motor cortex beta rhythm selective decrement of phase locking. The findings of the present experiment suggest the cortical origin of SAI that could result from the cortico- cortical activation of GABAergic-mediated inhibition onto the corticospinal neurons modulated by cholinergic activation able to reducing intralaminar inhibition and promoting intracolumnar inhibition. © 2012 by the American Physiological Society.

BACKGROUND Conflicting evidence exists on the efficacy and safety of bivalirudin administered as part of percutaneous coronary intervention (PCI) in patients with an acute coronary syndrome. METHODS We randomly assigned 7213 patients with an acute coronary syndrome for whom PCI was anticipated to receive either bivalirudin or unfractionated heparin. Patients in the bivalirudin group were subsequently randomly assigned to receive or not to receive a post-PCI bivalirudin infusion. Primary outcomes for the comparison between bivalirudin and heparin were the occurrence of major adverse cardiovascular events (a composite of death, myocardial infarction, or stroke) and net adverse clinical events (a composite of major bleeding or a major adverse cardiovascular event). The primary outcome for the comparison of a post-PCI bivalirudin infusion with no post-PCI infusion was a composite of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events. RESULTS The rate of major adverse cardiovascular events was not significantly lower with bivalirudin than with heparin (10.3% and 10.9%, respectively; relative risk, 0.94; 95% confidence interval [CI], 0.81 to 1.09; P = 0.44), nor was the rate of net adverse clinical events (11.2% and 12.4%, respectively; relative risk, 0.89; 95% CI, 0.78 to 1.03; P = 0.12). Post-PCI bivalirudin infusion, as compared with no infusion, did not significantly decrease the rate of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events (11.0% and 11.9%, respectively; relative risk, 0.91; 95% CI, 0.74 to 1.11; P = 0.34). CONCLUSIONS In patients with an acute coronary syndrome, the rates of major adverse cardiovascular events and net adverse clinical events were not significantly lower with bivalirudin than with unfractionated heparin. The rate of the composite of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events was not significantly lower with a post-PCI bivalirudin infusion than with no post-PCI infusion.

Background: The aim of this study was to explore the prevalence and impact of unexplained somatic symptoms during major depression. Sampling and Methods: A total of 560 consecutive outpatients with a major depressive episode according to the DSM-IV (text revision) were evaluated in 30 psychiatric facilities throughout Italy. 'Unexplained' somatic symptoms were evaluated using the 30-item Somatic Symptoms Checklist (SSCL-30). Somatic symptoms were considered explained if they were best accounted for as coming from a concomitant physical illness or side effects. Patients evaluated their own mood symptomatology using the Zung questionnaires for depression and anxiety and the Hypomania Checklist-32. Results: According to the SSCL-30, only 90 subjects (16.1%) had no unexplained somatic symptoms, while 231 (41.3%) had 1-5 unexplained symptoms and 239 (42.7%) had more than 5. Asthenia was the most commonly observed unexplained somatic symptom (53% of patients). Unexplained somatic symptoms were more common in females and among those suffering from major depression and depression not otherwise specified rather than in patients with recurrent major depression and bipolar disorders. No relationship between unexplained somatic symptoms and hypomanic features was observed. Conclusions: The presence of a large number of unexplained somatic symptoms is associated with more severe depression and higher rates of misdiagnosis and inappropriate treatment. Copyright © 2011 S.
