Objective: Cardiovascular complications contribute to postoperative morbidity and mortality in elderly hip fracture patients. Limited data are available regarding which preoperative risk factors predict cardiovascular course following hip fracture surgery (HFS). We used high sensitive troponin I (hs-TnI) assays and clinical parameters to identify preoperative risk factors associated with major adverse cardiac events (MACE) in elderly hip fracture patients. Method: From August 2014 to November 2016, 575 patients with hip fracture were enrolled in a retrospective, single-center registry...

INTRODUCTION: Type 2 Diabetes Mellitus (DM) is on the verge of becoming a pandemic in India. Type 2 DM patient have two to four times increased risk of carotid artery disease. Adipokines have been regarded recently as direct link between diabetes and atherosclerosis. Visceral Adipose Tissue Derived Serine Protease Inhibitor (VASPIN); one of the most recently discovered adipokine, inhibits the proteases responsible for insulin resistance, carotid plaque development and rupture. In literature, few studies have addressed the role of VASPIN in pathogenesis of Acute Coronary Syndrome (ACS) in patients with type 2 DM...

BACKGROUND AND PURPOSE: In the pharmaceutical industry risk assessments of chronic cardiac safety liabilities are mostly performed during late stages of preclinical drug development using in vivo animal models. Here, we explored the potential of human induced pluripotent stem cell-derived cardiomyocytes (hiPS-CMs) to detect chronic cardiac risks such as drug-induced cardiomyocyte toxicity. EXPERIMENTAL APPROACH: Video microscopy-based motion field imaging was applied to evaluate the chronic effect (over 72 h) of cardiotoxic drugs on the contractile motion of hiPS-CMs...

This prospective study included 152 elderly patients (mean age, 80 years; range, 72-88 years) with a hip fracture treated surgically. Comorbidities were evaluated, and B-type natriuretic peptide was measured at baseline and at postoperative days 4 and 5 in addition to troponin I. Major cardiac events were recorded, and 1-year mortality was assessed. Comorbidity models with the important multivariate predictors of 1-year mortality were analyzed. Overall, 9 patients (6%) experienced major cardiac events postoperatively during their hospitalization...

BACKGROUND: Packed red blood cell (PRBC) transfusion is required in hematology patients treated with chemotherapy for acute leukemia, autologous (auto) or allogeneic (allo) hematopoietic stem cell transplantation (HSCT). In certain situations like septic shock, hip surgery, coronary disease or gastrointestinal hemorrhage, a restrictive transfusion strategy is associated with a reduction of infection and death. A transfusion strategy using a single PRBC unit has been retrospectively investigated and showed a safe reduction of PRBC consumption and costs...

Myocardial infarction after hip fracture but before surgical repair is associated with a 30-day mortality as high as 30 % at 1 month. In Florence, since 2011, hip fractures are referred to a multidisciplinary hip fracture team including internal medicine specialists, anesthesiologists, and orthopaedic surgeons. The aim of the present investigation was to evaluate the clinical characteristics of patients with hip fracture who had at hospital admission a significant increase of troponin (>10 times reference levels), the diagnostic and therapeutic strategies adopted, and overall 1-year survival...

BACKGROUND: Hemodynamic optimization during surgery is of major importance to decrease postoperative morbidity and length of hospital stay. However, conventional cardiac output monitoring is rarely used at the bedside. Recently, the plethysmographic variability index (PVI) was described as a simplified alternative, using plug-and-play noninvasive technology, but its clinical utility remains to be established. METHODS/DESIGN: The hemodynamic optimization using the PVI (OPVI) trial is a multicenter randomized controlled two-arm trial, randomizing 440 patients at intermediate risk of postoperative complications after orthopedic surgery...

Sarcopenia is now clinically defined as a loss of muscle mass coupled with functional deterioration (either walking speed or distance or grip strength). Based on the FRAX studies suggesting that the questions without bone mineral density can be used to screen for osteoporosis, there is now a valid simple questionnaire to screen for sarcopenia, i.e., the SARC-F. Numerous factors have been implicated in the pathophysiology of sarcopenia. These include genetic factors, mitochondrial defects, decreased anabolic hormones (e...

Safety pharmacology studies that evaluate new drug entities for potential cardiac liability remain a critical component of drug development. Current studies have shown that in vitro tests utilizing human induced pluripotent stem cell-derived cardiomyocytes (hiPS-CM) may be beneficial for preclinical risk evaluation. We recently demonstrated that an in vitro multi-parameter test panel assessing overall cardiac health and function could accurately reflect the associated clinical cardiotoxicity of 4 FDA-approved targeted oncology agents using hiPS-CM...
