Background Heart failure (HF) is increasing in prevalence and is a major cause of morbidity and mortality despite advances in medical and device therapy. Autonomic imbalance, with excess sympathetic activation and decreased vagal tone, is an integral component of the pathophysiology of HF. Objectives The INOVATE-HF (Increase of Vagal Tone in Heart Failure) trial assessed the safety and efficacy of vagal nerve stimulation (VNS) among patients with HF and a reduced ejection fraction. Methods INOVATE-HF was a multinational, randomized trial involving 85 centers including patients with chronic HF, New York Heart Association functional class III symptoms and ejection fraction ≤40%. Patients were assigned to device implantation to provide VNS (active) or continued medical therapy (control) in a 3:2 ratio. The primary efficacy endpoint was composite of death from any cause or first event for worsening HF. Results Patients (n = 707) were randomized and followed up for a mean of 16 months. The primary efficacy outcome occurred in 132 of 436 patients in the VNS group, compared to 70 of 271 in the control group (30.3% vs. 25.8%; hazard ratio: 1.14; 95% confidence interval: 0.86 to 1.53; p = 0.37). During the trial, the estimated annual mortality rates were 9.3% and 7.1%, respectively (p = 0.19). Quality of life, New York Heart Association functional class, and 6-min walking distance were favorably affected by VNS (p < 0.05), but left ventricular end-systolic volume index was not different (p = 0.49). Conclusions VNS does not reduce the rate of death or HF events in chronic HF patients. (INcrease Of VAgal TonE in CHF [INOVATE-HF]; NCT01303718) © 2016 American College of Cardiology Foundation

LUME-Lung 2 investigated the efficacy/safety of nintedanib plus pemetrexed in patients with pretreated non-squamous non-small cell lung cancer (NSCLC).Patients with stage IIIB/IV or recurrent non-squamous NSCLC who had received one prior chemotherapy regimen were randomized (1:1 stratified by histology [adenocarcinoma/non-adenocarcinoma], prior bevacizumab, Eastern Cooperative Oncology Group performance status and presence of brain metastases) to receive intravenous pemetrexed 500mg/mBased on the pre-planned futility analysis of investigator-assessed PFS, conducted by an independent data monitoring committee, recruitment was halted on 18 June 2011 after 713 (n=353 nintedanib/pemetrexed; n=360 placebo/pemetrexed)/1300 planned patients had enrolled. There were no safety concerns. Subsequent analysis demonstrated a significant improvement in PFS favoring nintedanib/pemetrexed over placebo/pemetrexed (median 4.4 months vs 3.6 months; hazard ratio [HR]=0.83, 95% confidence interval [CI] 0.70-0.99, p=0.0435). There was no significant difference in OS (median 12.0 months vs 12.7 months; HR=1.01, 95% CI 0.85-1.21, p=0.8940) after 514 deaths. Nintedanib/pemetrexed resulted in a higher incidence of grade 3 elevated alanine aminotransferase (23.3% vs 7.3%), elevated aspartate aminotransferase (12.1% vs 1.7%) and diarrhea (3.5% vs 1.1%) compared with placebo/pemetrexed, but no difference in hypertension, bleeding or thrombosis.Although recruitment stopped prematurely, combining nintedanib with pemetrexed significantly prolonged PFS in patients with advanced non-squamous NSCLC after first-line chemotherapy, with a manageable safety profile.

CRA8007 Background: Heat shock protein 90 chaperone function is critical for the biological effects of several oncoproteins. Ganetespib (G) is a highly potent 2nd-generation Hsp90 inhibitor with a favorable safety profile and single-agent clinical activity.Based on synergistic preclinical interactions between docetaxel (D) and G, we conducted a randomized (1:1), international open-label study of D with or without G. Patients with advanced lung adenocarcinoma, one prior systemic therapy, and ECOG PS 0/1 were included. D was given at 75 mg/mEnrollment of 255 adenocarcinoma patients completed in November 2012; results are reported for this population. Patient characteristics were balanced (median age 60 years, males ~60%, PS 0 ~40% and never-smoker ~25%). For D+G vs. D the median number of cycles delivered was 5 vs. 4; the grade 3/4 adverse events were neutropenia 38% vs. 37%; fatigue 4% vs. 3%; anemia 7% vs. 6%; diarrhea 3% vs. 0; fever with neutropenia 8% vs. 2%. At the time of abstract submission OS HR was 0.69 (90% CI 0.48 to 0.99, p=0.093), the PFS HR was 0.70 (90% CI 0.53 to 0.94, p=0.012), and the ORR was 15% vs 11%, favoring D+G. For patients that were enrolled >6 months after diagnosis of advanced NSCLC (N=175; 69%), a prespecified stratification factor, the OS HR was 0.41 (90% CI 0.25 to 0.67, p=0.0009), the PFS HR was 0.47 (90% CI 0.32 to 0.69, p=0.0005), and the ORR was 16% vs 12%. Updated results for both populations above, as well as for the eLDH and mKRAS subsets, will be presented.D+G demonstrated improvement in OS, PFS, and ORR over D alone for second-line therapy of lung adenocarcinoma. A phase III study in second-line advanced adenocarcinoma patients (> 6 months from diagnosis) is ongoing (GALAXY-2).NCT01348126.

Background: The aim of this study was to analyze the demographic and clinical characteristics of male breast cancer patients in Serbia, and furthermore to determine overall survival and predictive factors for prognosis. Materials and Methods: In the period of 1996-2006 histopathological diagnosis of breast cancer was made in 84 males at the Institute for Oncology and Radiology of Serbia. For statistical analyses the Kaplan-Meier method, long-rank test and Cox proportional hazards regression model were used. Results: The mean age at diagnosis with breast cancer was 64.3±10.5 years with a range from 35-84 years. Nearly 80% of the tumors showed ductal histology. About 44% had early tumor stages (I and II) whereas 46.4% and 9.5% of the male exhibitied stages III and IV, respectively. Only 7.1% of male patients were grade one. One-fifth of all patients had tumors measuring ≤2 cm, and 14.3% larger than 5 cm. Lymph node metastasis was recorded in 40.4% patients and 47% relapse. Estrogen and progesterone receptor expression was positive in 66.7% and 58.3%, respectively. Among 14.3% of individuals tumor was HER2 positive. About two-thirds of all male patients had radical mastectomy (66.7%). Adjuvant hormonal (tamoxifene), systematic chemotherapy (CMF or FAC) and adjuvant radiotherapy were given to 59.5%, 35.7% and 29.8% patients respectively. Overall survival rates at five and ten years for male breast cancer were 55.0% and 43.9%, respectively. According to the multivariate Cox regression predictive model, a lower initial disease stage, a lower tumor grade, application of adjuvant hormone therapy and no relapse occurrence were significant independent predictors for good overall survival. Conclusions: Results of the treatment would be better if disease is discovered earlier and therefore health education and screening are an imperative in solving this problem.

To examine the effects of physical therapy (kinesitherapy and electrotherapeutic procedures) on the course of peripheral arterial occlusive disease by monitoring the changes in values of claudication distance and ankle-brachial indexes.Prospective randomized study included 47 patients with peripheral arterial occlusive disease manifested by intermittent claudications associated with ankle-brachial indexes values ranging from 0.5 to 0.9. Patients from the first group (25 pts) were treated with medicamentous therapy, walking exercises beyond the pain threshold, dynamic low-burden kinesi exercises and electrotherapeutic ageneses (interference therapy, diadynamic therapy, and electromagnetic field), while the second group of patients (22 pts) was treated with conventional non-operative treatment - medicamentous therapy and walking exercises. The values of newly established absolute claudication distance and ankle-brachial indexes were measured.Significant increase of absolute claudication distance in both groups of patients was registered, independently of therapeutic protocol applied (p<0.001), as well as the increase in the claudication distance interval in the physical therapy group. There was no significant increase in ankle-brachial indexes values in both groups of patients.Methods of physical therapy presented valuable supplement in non-operative treatment of peripheral arterial occlusive disease patients, improving their functional ability and thus postponing surgical treatment. However, further investigations including larger number of patients are needed.

This paper presents the most common disorders of pituitary function: acromegaly, hypopituitarism, diabetes insipidus and syndrome similar to diabetes insipidus, in terms of their importance in preoperative preparation of patients. Pituitary function manages almost the entire endocrine system using the negative feedback mechanism that is impaired by these diseases. The cause of acromegaly is a pituitary adenoma, which produces growth hormone in adults. Primary therapy of acromegaly is surgical, with or without associated radiotherapy. If a patient with acromegaly as comorbidity prepares for non-elective neurosurgical operation, then it requires consultation with brain surgeons for possible delays of that operation and primary surgical treatment of pituitary gland. If operative treatment of pituitary gland is carried out, the preoperative preparation (for other surgical interventions) should consider the need for perioperative glucocorticoid supplementation. Panhypopituitarism consequences are different in children and adults and the first step in diagnosis is to assess the function of target organs. Change of electrolytes and water occurs in the case of pituitary lesions in the form of central or nephrogenic diabetes insipidus as a syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Preoperative preparation of patients with pituitary dysfunction should be multidisciplinary, whether it is a neurosurgical or some other surgical intervention. The aim is to evaluate the result of insufficient production of pituitary hormones (hypopituitarism), excessive production of adenohypophysis hormones (acromegaly, Cushing's disease and hyperprolactinemia) and the influence of pituitary tumours in surrounding structures (compression syndrome) and to determine the level of perioperative risk. Pharmacological suppressive therapy of the hyperfunctional pituitary disorders can have significant interactions with drugs used in the perioperative period.

Introduction: The manifestations of autonomic nervous system (ANS) dysfunction in autoimmune diseases have been the subject of many studies. However, the published results pertaining to such research are controversial. Sudden cardiac death due to fatal arrhythmias is frequent in patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Objective: To analyse risk predictors of sudden cardiac death related to the degree of autonomic dysfunction. Methods: We performed cardiovascular ANS assessment in 90 patients in this case-controlled study, including 52 (6 male, 46 female) patients with SLE, 38 (6 male, 32 female) with RA and 41 (23 male, 17 female) healthy subjects. The methodology included a comprehensive ECG analysis (with Schiller software AT-10) of QTc interval, late potentials, short-term heart rate variability (HRV) and nonlinear HRV (Poincare plot) analysis; 24-hour Holter ECG monitoring with ECG QTc interval analysis, HRV analysis; 24-hour blood pressure monitoring with systolic and diastolic blood pressure variability; cardiovascular autonomic reflex tests (according to Ewing). Vagal dysfunction was established by performing 3 tests: Valsalva maneuver, deep breathing test and heart rate response to standing test. Dysfunction of the sympathetic nervous system was examined by applying 2 tests: blood pressure response to standing and handgrip test. Results: In all cardiovascular reflex tests, the frequencies of abnormal results were significantly higher among the patients than among the healthy subjects. Severe autonomic dysfunction was more common in RA. QTc interval was more prolonged in patients with SLE. Both diseases were associated with depressed heart rate variability compared to controls, the reduction being greater in RA patients. In the patients with SLE, autonomic dysfunction is predominantly with higher sympathetic activity while in RA vagal predominance is evident. Conclusion: SLE and RA are associated with severe autonomic dysfunction and the presence of significant risk predictors related to the onset of sudden cardiac death.

Introduction: Thrombocytopenia is a common finding in chronic liver diseases and it is caused by different pathophysiological mechanisms. Immunologic thrombocytopenic purpura (ITP) in hepatitis C infection is a distinct clinical entity. Possible reasons for ITP in this case could be capabillity of HCV to induce autoimmune phenomena but also immunomodulatory effects of interferon that is used for HCV infection treatment. The specific laboratory parameters for ITP diagnosis during HCV infection have not been defined yet. Case Outline: A 37-year-old patient diagnosed with HCV infection was treated with PEG-interferon and Ribavirin during 24 weeks. The partial response was achieved after the therapy with reduction of viral replications. One month after therapy completion, the patient was hospitalized due to skin haemorrhagic syndrome and a serious degree of thrombocytopenia (2×109/l). The number and megakaryocyte morphology in bone marrow aspirate were normal. An assay of thrombocyte kinetics by radioactive marker (Indium 111) showed rapid thrombocyte destruction and their early sequestration in the spleen. Conclusion: Results of assays about thrombocyte kinetics during HCV infection show enchanced thrombocyte destruction in the liver. Accordingly, the most important parameter for ITP diagnosis in HCV infection, in this case, was rapid thrombocyte destruction and their early sequestration in the spleen approved by Indium kinetics. Also, in support of ITP is the increment of thrombocyte number during therapy with intravenous immunoglobulins. Thrombocytopenia was developing during antiviral therapy and on indirect conclusion is that viral replication is not the reason for it.

Antiphospholipid syndrome (APS) or Hughes syndrome represents a systemic autoimmune disorder characterized by arterial and/or venous thrombosis, multiple and recurrent fetal losses, accompanied by persistently elevated levels of antiphospholipid antibodies (aPL). This syndrome is considered primary if unassociated with any other connective tissue disease, or secondary if it appears in association with other autoimmune disorders, mainly systemic lupus erythematosus. Cardiac manifestations in APS are integral part of the syndrome. aPL are involved in the pathogenesis of pseudoinfective endocarditis (Libman Sacks) and other valvular manifestations presented as their thickening and dysfunction. Intracardiac thrombi and myxomas, pulmonary hypertension and left ventricular dysfunction are also distinguishing features of APS. On the other hand, accelerated atherosclerosis, proven in APS and also aPL mediated, is accountable for the development of coronary and peripheral artery disease. This leads to higher cardiovascular mortality rate in the population of patients with low incidence of the traditional atherosclerosis risk factors. Furthermore, recent studies implied that presence of certain aPL could be a risk factor for a specific cardiac manifestation. Bearing all this in mind, early diagnosis of cardiac manifestations, control and abolition of traditional risk factors, as well as close cardiac follow-up of APS patients, are crucial in reducing their cardiovascular mortality. © 2015, Serbia Medical Society.

Sepsis-associated acute kidney injury (SA-AKI) severely impacts morbidity and mortality in surgical patients with sepsis. Matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) have an important role in pathophysiology of sepsis but they have been unexplored in SA-AKI. We aimed to investigate the role of MMP-9 and TIMP-1 in septic surgical patients with SA-AKI and to evaluate them as diagnostic biomarkers of SA-AKI. This prospective observational study compared 53 major abdominal surgery patients with sepsis divided into SA-AKI (n = 37) and non-SA-AKI (n =16) group to 50 controls without sepsis matched by age, gender, comorbidities and type of surgery. Blood and urine samples from septic patients were collected on admission to ICU and 24, 48, 72 and 96 h later and once from the controls. The levels of MMP-9, TIMP-1, neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1, urea and creatinine were measured. MMP-9/TIMP-1 ratio and disease severity scores, such as Sequential Organ Failure Assessment (SOFA), were calculated. Septic patients with SA-AKI had higher serum TIMP-1 levels and lower serum MMP-9 levels and lower MMP-9/TIMP ratio, compared to septic patients without SA-AKI and controls. The levels of these biomarkers did not change significantly over time. MMP-9, TIMP-1 and MMP-9/TIMP-1 ratio correlated with urea, creatinine, NGAL, and SOFA scores. Moreover, using the area under ROC curve, we showed that TIMP-1 and MMP-9/TIMP-1 ratio, but not MMP-9, were good diagnostic biomarkers of SA-AKI. We report for the first time the potential diagnostic value of TIMP-1 and MMP-9/TIMP-1 ratio in SA-AKI.
