    ABSTRACT: Background: It is currently not known whether treatment with anti-vascular endothelial growth factor agents for metastatic renal cell carcinoma (mRCC) can be safely discontinued in patients achieving a complete response (CR). Objective: To assess outcomes for patients with mRCC achieving CR on targeted therapy (TT) and the survival of patients discontinuing TT after CR. Design, setting, and participants: A national registry was used to identify patients achieving CR during first-line TT using bevacizumab, sunitinib, sorafenib, or pazopanib. Outcome measurements and statistical analysis: Relationships with outcomes were analysed using a log-rank test. Results and limitations: A total of 100 patients achieving CR were identified out of 2803 patients. The median time to CR was 10.1 mo. Median progression-free survival (PFS) from TT initiation was 3.8 yr (95% confidence interval [CI] 2.9-4.6 yr) and the 5-yr overall survival (OS) was 80% (95% CI 70-91%). Patients discontinuing TT within 1 mo after achieving CR and those continuing TT beyond CR had similar OS (CI for difference in 2-yr post-CR OS -13% to 19%; p=0.3) and PFS (CI for difference in 2-yr post-CR PFS -29% to 17%; p=0.7). The limitations include the retrospective, registry-based data analysis. Conclusions: Achievement of CR on TT for mRCC was associated with excellent long-term prognosis. No significant differences in post-CR survival were observed between patients discontinuing TT after the date of CR and those who continued on TT, although the wide CIs cannot exclude important differences between the groups. Patient summary: According to this registry-based analysis, patients with metastatic renal cancer with no signs of disease (complete response) after treatment with targeted agents experience excellent long-term survival even if the treatment does not continue beyond the date of complete response.

    ABSTRACT: Background: The aim of the present retrospective study was to analyze clinical outcome and risk factors associated with treatment outcomes according to KRAS status in patient with metastatic colorectal cancer (mCRC) treated with bevacizumab (bev) plus chemotherapy in the first-line setting. Methods: We performed observational study on 1622 patients with mCRC treated with bev plus oxaliplatin- or irinotecan-based chemotherapy, and correlated treatment outcomes with KRAS mutation status. The primary endpoint was progression-free survival (PFS) and additionally overall survival (OS). Adverse events of bevacizumab and risk factors including location of metastases were evaluated. Results: Mutation in KRAS was present in 40.6% of mCRC cases. The median PFS in patients with wild-type KRAS (wtKRAS) vs mutant KRAS was 11.5 vs 11.4 months, respectively. The median OS was 30.7 vs 28.4 months (p = 0.312). Patients with KRAS mutation had lung metastases more frequently than wtKRAS individuals (32.0% vs 23.8%; p = 0.001). We observed no difference in clinical outcome between hepatic and extrahepatic metastatic disease. Conclusion: KRAS mutation does not interfere with clinical benefit from first-line treatment with bevacizumab plus chemotherapy in mCRC patients.

    ABSTRACT: Histopathology imaging and gene expression profiling are two fundamental investigative techniques which allow the analysis of biological specimens from different perspectives. Given their apparent divergence in data representation, they are usually used separately, being connected only at the higher levels of data analysis. In this work we demonstrate how gene expression can be used directly for guiding the selection of prognostically-relevant imaging features. Our method is applied to the analysis of a breast cancer data set, but is not limited to this pathology.

    ABSTRACT: Background: Severe sepsis/septic shock is associated with high mortality. In Central Europe, there is a dearth of information on the prevalence and treatment of severe sepsis. The EPOSS (Data-based Evaluation and Prediction of Outcome in Severe Sepsis) project launched in 2011 was aimed at collecting data on patients with severe sepsis/septic shock. Methods: The EPOSS study processes data from the EPOSS project database, and is a retrospective, multicentre, observational study. This included all consecutive patients aged 18 and over who were admitted to participating ICUs from 1 January 2011 to 5 November 2013 and met the inclusion criteria of severe sepsis/septic shock. The primary endpoint was to analyse the relationship between in-hospital mortality (either in ICU or after discharge from ICU) and the type and number of fulfilled diagnostic and treatment interventions during the first 6 h after the diagnosis of severe sepsis/septic shock. Results: The collected dataset involved 1082 patients meeting the criteria of severe sepsis/septic shock. Following data validation, a final dataset of 897 patients was obtained. The average age of the patient group was 64.7 years; mortality at discharge from EPOSS ICUs was 35.5% and from hospital 40.7%. Of the 10 evaluated diagnostic and treatment interventions within the initial 6 hours of identifying severe sepsis/septic shock (i.e. fulfilment of SSC bundles), four or five diagnostic and treatment interventions were administered to 58.4% patients. Combined diagnostic and treatment interventions associated with the lowest in-hospital mortality were: CVP of ≥8-12 mm Hg & MAP of ≥65 mm Hg & Urine output at ≥0.5 mL/kg/h & Lactate of ≤4.0 mmol/L & Initial lactate measured & Antibiotics in the first hour. Lactate at <4 mmol/L and MAP of ≥65 mm Hg remained statistically significant even after adjustment for patient age and APACHE II score. Statistically significantly increased in-hospital mortality was found in patients admitted from general departments (45.7%) or from other ICUs (41.6%), compared to a lower in-hospital mortality of patients transferred from outpatient clinics (26.5%) or Emergency (38.0%). Severe sepsis/septic shock patients transferred from the department of internal medicine were associated with a higher in-hospital mortality (45.1%) than surgical patients (35.5%). Conclusions: The most effective measures associated with the lowest in-hospital mortality in septic shock patients were CVP of ≥8-12 mm Hg, MAP of ≥65 mm Hg, urine output at ≥0.5 mL/kg/h, initial lactate level of ≤4.0 mmol/L and administration of antibiotics within the first hour.

    ABSTRACT: Background: The clinical importance of assessing the fetal KEL genotype is to exclude 'K'-positive fetuses (genotype KEL1/KEL2) in 'K'-alloimmunized pregnant women (genotype KEL2/KEL2). Noninvasive assessment of the fetal KEL genotype is not yet available in the Czech Republic. Objective: The aim of this study was to assess the fetal KEL1/KEL2 genotype from cell-free fetal DNA in the plasma of KEL2/KEL2 pregnant women. Methods: The fetal genotype was assessed by minisequencing (a dilution series including control samples). A total of 138 pregnant women (between the 8th and 23rd gestational week) were tested by minisequencing. The fetal genotype was further verified by analysis of a buccal swab from the newborn. Results: Minisequencing proved to be a reliable method. In 2.2% (3/138) of the examined women, plasma sample testing failed; 94.8% (128/135) had the KEL2/KEL2 genotype, and a total of 3.1% of fetuses (4/128) had the KEL1/KEL2 genotype. Sensitivity and specificity reached 100% (p < 0.0001). Conclusion: Minisequencing is a reliable method for the assessment of the fetal KEL1 allele from the plasma of KEL2/KEL2 pregnant women.

    ABSTRACT: Vitamin D deficiency has been implicated in the epidemiology of common malignancies including colorectal cancer. We studied consecutive blood levels of 25-hydroxycholecalciferol (25-OHD) in relation to other clinical and laboratory variables in metastatic colorectal cancer patients to ascertain whether their variations may be prognostic or predictive parameters of survival outcomes. Eighty four patients treated with first-line oxaliplatin-based chemotherapy with or without bevacizumab were included. The patients were enrolled on the intent-to-treat basis considering their performance status, comorbidities and laboratory parameters to be medically apt for intensive chemotherapy. Overall survival and progression-free survival were selected as the primary outcomes. Progression free survival and overall survival medians were 15.4 months and 41.2 months, respectively. The cut-off levels of 40 nmol/l for 25-OHD and 11 µg/l for first CEA were identified to be clinical decision levels stratifying patients to the respective prognostic groups. We found that the most consistent outcome predictors were i) any patient surgery, ii) CEA and, independently, iii) time-related blood levels of 25-OHD. We confirmed fundamental and consistent vitamin D deficiency in metastatic colorectal cancer. We demonstrated that all patients with at least one blood level above 40 nmol/l versus all below this cut-off showed profound differences in their disease outcomes. The primary disease stage or time to metastatic stage did not influence the predictive power of blood 25-OHD levels, implying that the time-course pattern of 25-OHD but not the first single measurement may be an independent prognostic factor.

    ABSTRACT: Drug addiction is commonly associated with depression and comorbid patients also suffer from higher cravings and increased relapse rate. To address this issue preclinically we combined the olfactory bulbectomy (OBX) model of depression and intravenous methamphetamine self-administration procedure in rats to assess differences in relapse-like behavior. Male Sprague-Dawley rats were divided randomly into two groups; in one group the bilateral olfactory bulbectomy (OBX) was performed while the other group was sham operated. After recovery, intracardiac catheter was implanted. Intravenous self-administration procedure was conducted in operant boxes using nose-poke operandi (Coulbourn Instruments, Inc., USA) under fixed ratio 1 schedule of reinforcement. Methamphetamine was available at dose 0.08 mg/kg/infusion. After stable methamphetamine intake was maintained, a period of forced abstinence was initiated and rats were kept in their home-cages for 14 days. Finally, one reinstatement session was conducted in operant boxes with no drug delivery. In the reinstatement session the mean of 138.4 active nose-pokes was performed by the OBX group, while the sham group displayed 41 responses, i.e. 140 % and 48 % of basal nose-poking during maintenance phase in OBX and sham operated group respectively. OBX group also showed significantly more passive nose-pokes indicating hyperactive behavioral traits in bulbectomized rats. However, the % of active operandum preference was equal in both groups. Olfactory bulbectomy model significantly increased reinstatement of methamphetamine seeking behavior. This paradigm can be used to evaluate potential drugs that are able to suppress the drug-seeking behavior.

    ABSTRACT: Background: The role of co-morbidities in the prognosis of patients hospitalized for AHF was examined using the AHEAD (A - atrial fibrillation, H - haemoglobin<130g/l for men and 120g/l for women (anaemia), E - elderly (age>70years), A - abnormal renal parameters (creatinine>130μmol/l), D - diabetes mellitus) scoring system. Methods: AHEAD - multicentre prospective Czech registry of AHF patients; GREAT registry - international cohort of AHF patients. Data from 5846 consecutive patients hospitalized for AHF (AHEAD registry; derivation cohort) were analysed to build the AHEAD score. Each risk factor of the AHEAD score was counted as 1 point. The model was validated externally using an international cohort of similar patients in the GREAT registry (6315). Results: Main outcome was one year all-cause mortality. The mean age of patients was 72±12years, with 61.6% of patients aged >70years; 43.4% were women. Atrial fibrillation was present in 30.7%, anaemia in 38.2%, creatinine >130mmol/l (abnormal renal parameters) in 30.1%, and diabetes mellitus in 44.0%. The mean AHEAD score was 2.1. In patients with AHEAD scores of 0-5, the one-year mortality rates were 13.6%, 23.4%, 32.0%, 41.1%, 47.7%, and 58.2%, respectively (p<0.001), and the 90month mortality rates were 35.1%, 57.3%, 73.5%, 84.8%, 88.0%, and 91.7%, respectively (p<0.001). Conclusion: The AHEAD is a simple scoring system based on the analysis of co-morbidities for the estimation of the short and long term prognosis of patients hospitalized for AHF.

    ABSTRACT: AimsThis paper aims to investigate whether intraepidermal nerve-fibre density (IENFD) may be used as a marker of the course of neuropathy in patients with Type 2 diabetes mellitus.Methods Skin biopsies from the distal leg were serially evaluated in a group of 30 patients with Type 2 diabetes mellitus (median age 60 years, 17 men) with a short duration of diabetes (< 3 years) and good glucose control, and in 23 age- and sex-matched controls. The time intervals between biopsies were > 2 years (median 33.8 months). Eighteen patients with Type 2 diabetes mellitus had symptoms or signs of distal symmetrical diabetic polyneuropathy, 12 had no neuropathy.ResultsAt first skin biopsy, IENFD was normal in all controls and in patients without neuropathy (mean 9.5 and 7.9 fibres/mm, respectively) compared with abnormal IENFD in 77.8% in patients with polyneuropathy (mean 3.4 fibres/mm). The annual rate of intraepidermal nerve-fibre (IENF) loss expressed as a percentage of the first IENFD value in patients with diabetic polyneuropathy was significantly higher [mean (se), 11.95 (3.82)%] compared with controls [1.92 (1.81)%, P < 0.001] and similar to patients without polyneuropathy [12.16 (4.38)%]. The rate of IENF loss did not correlate with degree of glucose control.Conclusions The annual rate of IENF loss in patients with Type 2 diabetes mellitus was several times higher than that of healthy participants, irrespective of the presence of signs or symptoms of diabetic polyneuropathy at initial evaluation. The change in IENFD is not linear and should be expressed as a proportion of initial IENFD to serve as a marker of the course of diabetic neuropathy.This article is protected by copyright.

    ABSTRACT: Preventing relapse to drug abuse is one of the struggles faced by clinicians in order to treat patients with substance use disorders (DSM-5). There is a large body of clinical evidence suggesting differential characteristics of the disorder in men and women, which is in line with preclinical findings as well. The aim of this study was to assess differences in relapse-like behavior in methamphetamine (METH) seeking after a period of forced abstinence, which simulates the real clinical situation very well. Findings from such study might add new insights in gender differences in relapse mechanisms to previous studies, which employ a classical drug or cue-induced reinstatement procedure following the extinction training. Adult male and female Sprague-Dawley rats were used in IV self-administration procedure conducted in operant boxes using nose-poke operandi (Coulborn Instruments, USA). Active nose-poke resulted in activation of the infusion pump to deliver one intravenous infusion of METH (0.08 mg/kg). After baseline drug intake was established (maintenance phase), a period of forced abstinence was initiated and rats were kept singly in their home cages for 14 days. Finally, one reinstatement session in operant boxes was conducted. Females were found to self-administer significantly lower dose of METH. The relapse rate was assessed as a number of active nose-pokes during the reinstatement session, expressed as a percentage of active nose-poking during the maintenance phase. Females displayed approximately 300% of active nose-pokes compared to 50% in males. This indicates higher vulnerability to relapse of METH seeking behavior in female rats. This effect was detected in all females, independently of current phase of their estrous cycle. Therefore, this paradigm using operant drug self-administration and reinstatement of drug-seeking after forced abstinence model can be used for preclinical screening for potential new anti-relapse medications specific for women.

    ABSTRACT: The aim of the study was to evaluate whether the sequential hybrid approach combining surgical CryoMaze followed by the radiofrequency catheter ablation can improve freedom from atrial arrhythmias. Thirty-five patients with persistent atrial fibrillation underwent a CryoMaze procedure in conjunction with cardiac surgery for structural heart disease. Three months after surgery, all patients underwent a 7-day ECG Holter followed by an electrophysiological study and mapping of the left and right atria. All pulmonary veins were re-isolated and all ablation lines were completed, if necessary, using radiofrequency energy. Patients were followed-up at 3, 6 and 12 months after the catheter ablation. Before the mapping study and radiofrequency ablation, 9 patients (26%) had ongoing atrial fibrillation or atrial tachycardia, 10 patients (28%) had paroxysmal atrial tachyarrhythmia and 16 patients (46%) had sinus rhythm on the 7-day Holter monitoring. During the electrophysiological procedure, complete cryoablation lines around the left pulmonary veins were found in 29 patients (83%), around the right pulmonary veins in 25 patients (71%), between the superior veins in 20 cases (57%), between the inferior veins in 27 cases (77%), across the mitral isthmus in 12 patients (34%) and across the cavo-tricuspid isthmus in one patient (3%). Arrhythmia-free survival rate off antiarrhythmic drugs after re-isolation of the veins and completion of the lines was 86% at 12 months. Ablation lines created using surgical CryoMaze are often incomplete. Sequential surgical CryoMaze procedures followed by catheter ablation significantly increase freedom from arrhythmia in patients with persistent atrial fibrillation.

    ABSTRACT: To retrospectively compare the efficacy of two irinotecan-based chemotherapy regimens combined with bevacizumab in first-line therapy of metastatic colorectal cancer (mCRC). The data of 558 patients with mCRC treated with first-line bevacizumab plus irinotecan-containing regimen were obtained from the national CORECT registry that collects data of all patients with mCRC treated with targeted-agents. The treatment outcomes of patients treated with bevacizumab plus irinotecan, 5-fluorouracil and folinic acid (FOLFIRI) were compared to patients treated with bevacizumab plus irinotecan and capecitabine (XELIRI). Among 4,312 patients with CRC treated with bevacizumab, only 13% (558) received irinotecan-based chemotherapy. No significant differences were observed in terms of progression-free survival and overall survival between FOLFIRI and XELIRI groups. Moreover, the toxicity of both regimens was also comparable. This retrospective analysis confirms the comparable activity of FOLFIRI and XELIRI regimens when combined with bevacizumab. Copyright© 2015 International Institute of Anticancer Research (Dr. John G.

    ABSTRACT: This contribution introduces a new web-based OPTIMED platform for an effective harmonisation of medical and healthcare curriculum. Behind the engineering background stays an original methodology covering planning model based on formal parameterisation of curriculum, which fully support the outcome-based approach to education. With the use of developed system curriculum, designers and senior guarantors can provide a clear and transparent composition of compulsory and optional courses, and easily identify potential duplicities and overlaps across a domain of medical and healthcare education. For students, it means an absolutely new way of how to understand what is really taught during a learning period, including all necessary meta information. All members across the academic community are able to search and consequently display in detail the most important domains related to the particular year, term, course, medical discipline or topic. The presented solution significantly enhances the transparency and continuity of the environment in which the authors of the teaching materials as well as their consumers work daily. Suggestions for future improvements of the OPTIMED platform are discussed.

    ABSTRACT: The study aimed to compare two prognostic models in terms of progression-free survival (PFS), median overall survival (OS), and 1-year survival in patients treated first-line with sunitinib for metastatic renal cell carcinoma (mRCC). Data from patients who met prognostic model criteria for recording of baseline parameters and outcomes in the Czech Patient Registry RENal Information System (RENIS) were included in the retrospective analysis (n = 495). Performance of the modified Memorial Sloan Kettering Cancer Center (MSKCC) model and International Database Consortium (IDC) model was compared. PFS and OS were estimated using the Kaplan-Meier method. The statistical significance of differences in Kaplan-Meier estimates was assessed using the log-rank test. Median OS for prognostic groups according to MSKCC and IDC criteria, respectively, was 39.5 months (95 % confidence interval [CI]: 23.9-55.2) versus 44.3 months (95 % CI: 31.6-56.9) for favourable-risk patients (no adverse factors), 28.5 months (95 % CI: 20.1-36.8) versus 24.8 months (95 % CI: 19.8-29.8) for intermediate-risk patients (1-2 adverse factors), and 10.6 months (95 % CI: 6.3-14.8) versus 9.3 months (95 % CI: 5.1-13.5) for poor-risk patients (≥3 adverse factors). The majority of MSKCC poor-risk patients (54.1 %, n = 72) were reclassified as intermediate-risk using IDC criteria, and 20.2 % (n = 61) of MSKCC intermediate-risk patients were reclassified to the IDC favourable-risk group. Both prognostic models were validated in the present cohort. Use of the IDC model resulted in an upward shift in prognostic assessment compared to the MSKCC model.

    ABSTRACT: Aim: To compare the prognostic accuracy of six scoring models for up to three-year mortality and rates of hospitalisation due to acute decompensated heart failure (ADHF) in STEMI patients. Methods and results: A total of 593 patients treated with primary PCI were evaluated. Prospective follow-up of patients was ≥3 years. Thirty-day, one-year, two-year, and three-year mortality rates were 4.0%, 7.3%, 8.9%, and 10.6%, respectively. Six risk scores--the TIMI score and derived dynamic TIMI, CADILLAC, PAMI, Zwolle, and GRACE--showed a high predictive accuracy for six- and 12-month mortality with area under the receiver operating characteristic curve (AUC) values of 0.73-0.85. The best predictive values for long-term mortality were obtained by GRACE. The next best-performing scores were CADILLAC, Zwolle, and Dynamic TIMI. All risk scores had a lower prediction accuracy for repeat hospitalisation due to ADHF, except Zwolle with the discriminatory capacity for hospitalisation up to two years (AUC, 0.80-0.83). Conclusions: All tested models showed a high predictive value for the estimation of one-year mortality, but GRACE appears to be the most suitable for the prediction for a longer follow-up period. The tested models exhibited an ability to predict the risk of ADHF, especially the Zwolle model.

    ABSTRACT: Obesity is clearly associated with increased morbidity and mortality rates. However, in patients with acute heart failure (AHF), an increased BMI could represent a protective marker. Studies evaluating the "obesity paradox" on a large cohort with long-term follow-up are lacking. Using the AHEAD database (a Czech multi-centre database of patients hospitalised due to AHF), 5057 patients were evaluated; patients with a BMI <18.5 kg/m2 were excluded. All-cause mortality was compared between groups with a BMI of 18.5-25 kg/m2 and with BMI >25 kg/m2. Data were adjusted by a propensity score for 11 parameters. In the balanced groups, the difference in 30-day mortality was not significant. The long-term mortality of patients with normal weight was higher than for those who were overweight/obese (HR, 1.36; 95% CI, 1.26-1.48; p<0.001)). In the balanced dataset, the pattern was similar (1.22; 1.09-1.39; p<0.001). A similar result was found in the balanced dataset of a subgroup of patients with de novo AHF (1.30; 1.11-1.52; p = 0.001), but only a trend in a balanced dataset of patients with acute decompensated heart failure. These data suggest significantly lower long-term mortality in overweight/obese patients with AHF. The results suggest that at present there is no evidence for weight reduction in overweight/obese patients with heart failure, and emphasize the importance of prevention of cardiac cachexia.

    ABSTRACT: To identify the incidence of asymptomatic and symptomatic (i.e. causing pain, hydronephrosis, venous thrombosis, acute lymphedema of the lower or urinary urgency) lymphoceles, as well as risk factors for their development, through a prospective study of patients undergoing sole pelvic or combined pelvic and paraaortic lymphadenectomy for gynecological cancer. Patients with endometrial, ovarian or cervical cancer scheduled for sole pelvic or combined pelvic and paraaortic lymphadenectomy as a primary surgical treatment or salvage surgery for recurrence were enrolled at single institution from February 2006 to November 2010 and prospectively followed-up with ultrasound. Of 800 patients who under went sole pelvic or combined pelvic and paraaortic lymphadenectomy for gynecological cancer, the overall incidence of lymphoceles was 20.2%, with symptomatic lymphoceles occurring in 5.8% of all patients. Lymphoceles are predominantly located on the left pelvic side wall. Lymphadenectomy in ovarian cancer, a higher number of lymph nodes obtained (>27), and radical hysterectomy in cervical cancer were found to be independent risk factors for the development of symptomatic lymphoceles. The overall incidence of lymphocele development after lymphadenectomy for gynecological cancer remains high. However the majority of lymphoceles are only incidental finding without clinical impact. A symptomatic lymphocele is an uncommon event, occurring in only 5.8% of patients. Symptomatic lymphoceles tend to develop earlier than asymptomatic. Although such risk factors are hard to avoid, patients known to be at an increased risk of developing symptomatic lymphoceles can be counselled appropriately and followed-up for specific symptoms relating to lymphocele development.
