Relationship of quality of life scores with baseline characteristics and outcomes in the African-American heart failure trial.

To characterize the quality of life (QOL) in the African-American Heart Failure Trial (A-HeFT) for factors associated with baseline score, relation of score to prognosis, and response to therapy with a fixed-dose combination of isosorbide dinitrate/hydralazine (FDC I/H). Limited data exist on QOL scores in African-American heart failure patients or on the prognostic value of theses scores in any population. Finally, the effect of FDC I/H on QOL scores, particularly in A-HeFT, is not known.



A-HeFT randomized 1050 African-American patients with New York Heart Association (NYHA) Class III-IV heart failure and systolic dysfunction. QOL measurements using Minnesota Living with Heart Failure Questionnaire (MLHFQ) were done at baseline and 3-month intervals. At baseline, worse MLHFQ scores were associated with younger age, female sex, greater body mass index, nonischemic etiology, high heart rate and NYHA Class, low systolic blood pressure, and chronic obstructive pulmonary disease. Both baseline and change in MLHFQ score were associated with a higher risk for combined all-cause mortality or heart failure hospitalization (baseline P < .0001, change at 3 months P=.001, and at 6 months P=.0008), but not mortality. Treatment with FDC I/H significantly improved MLHFQ score compared with placebo.



In A-HeFT, baseline QOL (MLHFQ) scores and change in score were predictive of combined HF morbidity and mortality outcomes. FDC I/H consistently improved QOL scores in A-HeFT compared with placebo.
PHASES Score for Prediction of Intracranial Aneurysm Growth.

Growth of an intracranial aneurysm occurs in around 10% of patients at 2-year follow-up imaging and may be associated with aneurysm rupture. We investigated whether PHASES, a score providing absolute risks of aneurysm rupture based on 6 easily retrievable risk factors, also predicts aneurysm growth.



In a multicenter cohort of patients with unruptured intracranial aneurysms and follow-up imaging with computed tomography angiography or magnetic resonance angiography, we performed univariable and multivariable Cox regression analyses for the predictors of the PHASES score at baseline, with aneurysm growth as outcome. We calculated hazard ratios and corresponding 95% confidence intervals (CI), with the PHASES score as continuous variable and after division into quartiles.



We included 557 patients with 734 unruptured aneurysms. Eighty-nine (12%) aneurysms in 87 patients showed growth during a median follow-up of 2.7 patient-years (range 0.5-10.8). Per point increase in PHASES score, hazard ratio for aneurysm growth was 1.32 (95% CI, 1.22-1.43). With the lowest quartile of the PHASES score (0-1) as reference, hazard ratios were for the second (PHASES 2-3) 1.07 (95% CI, 0.49-2.32), the third (PHASES 4) 2.29 (95% CI, 1.05-4.95), and the fourth quartile (PHASES 5-14) 2.85 (95% CI, 1.43-5.67).



Higher PHASES scores were associated with an increased risk of aneurysm growth. Because higher PHASES scores also predict aneurysm rupture, our findings suggest that aneurysm growth can be used as surrogate outcome measure of aneurysm rupture in follow-up studies on risk prediction or interventions aimed to reduce the risk of rupture.
Genetic effects on sleep/wake variation of seizures.

There is a complex bidirectional relationship between sleep and epilepsy. Sleep/wake timing of seizures has been investigated for several individual seizure types and syndromes, but few large-scale studies of the timing of seizures exist in people with varied epilepsy types. In addition, the genetic contributions to seizure timing have not been well studied.



Sleep/wake timing of seizures was determined for 1,395 subjects in 546 families enrolled in the Epilepsy Phenome/Genome Project (EPGP). We examined seizure timing among subjects with different epilepsy types, seizure types, epilepsy syndromes, and localization. We also examined the familial aggregation of sleep/wake occurrence of seizures.



Seizures in nonacquired focal epilepsy (NAFE) were more likely to occur during sleep than seizures in generalized epilepsy (GE), for both convulsive (odds ratio [OR] 5.2, 95% confidence interval [CI] 3.59-7.52) and nonconvulsive seizures (OR 4.2, 95% CI 2.48-7.21). Seizures occurring within 1 h of awakening were more likely to occur in patients with GE than with NAFE for both convulsive (OR 2.3, 95% CI 1.54-3.39) and nonconvulsive (OR 1.7, 95% CI 1.04-2.66) seizures. Frontal onset seizures were more likely than temporal onset seizures to occur during sleep. Sleep/wake timing of seizures in first-degree relatives predicted timing of seizures in the proband.



We found that sleep/wake timing of seizures is associated with both epilepsy syndrome and seizure type. In addition, we provide the first evidence for a genetic contribution to sleep/wake timing of seizures in a large group of individuals with common epilepsy syndromes.
Progressive disease after ABMT for Hodgkin’s disease

A major limitation of ABMT for relapsed/refractory Hodgkin’s disease is disease recurrence post-transplantation. We retrospectively reviewed 68 patients undergoing ABMT from January 1987 to June l993. All received a uniform preparatory regimen (CBV). The median patient age was 30; 75% received prior radiation therapy and all patients received prior chemotherapy. Thirty-one percent presented at the time of transplantation with tumor masses larger than 10 cm. Sixty-two percent received autologous marrow alone and 38% PBPC with or without autologous bone marrow. Overall and progression-free survival are 43 and 36% at 5 years. Median follow-up for survivors is 59 months. Multivariate analysis revealed that tumor bulk was the most powerful poor prognostic factor for both survival and progression-free survival. Those transplanted with non-bulky tumors had an overall survival and progression-free survival of 52 and 44%, respectively, compared to those transplanted with bulky tumors who had an overall survival and progression-free survival of 22 and 16% (P = 0.03 and P = 0.04, respectively). Twenty-seven patients have relapsed. Four relapsed more than 2 years after ABMT. Four of the 27 patients who have relapsed remain alive, two without evidence of disease. The time after transplant to relapse was prognostically important, with no patients who relapsed within 6 months of ABMT still being alive, compared with 25% of patients who relapsed 7 or more months after ABMT who are still alive. We conclude that salvage therapy for relapse after ABMT is appropriate, as some patients may achieve prolonged survival. The time from transplant to relapse is an important survival predictor.
Inducible CYP2J2 and Its Product 11,12-EET Promotes Bacterial Phagocytosis: A Role for CYP2J2 Deficiency in the Pathogenesis of Crohn’s Disease?

The epoxygenase CYP2J2 has an emerging role in inflammation and vascular biology. The role of CYP2J2 in phagocytosis is not known and its regulation in human inflammatory diseases is poorly understood. Here we investigated the role of CYP2J2 in bacterial phagocytosis and its expression in monocytes from healthy controls and Crohns disease patients. CYP2J2 is anti-inflammatory in human peripheral blood monocytes. Bacterial LPS induced CYP2J2 mRNA and protein. The CYP2J2 arachidonic acid products 11,12-EET and 14,15-EET inhibited LPS induced TNFα release. THP-1 monocytes were transformed into macrophages by 48h incubation with phorbol 12-myristate 13-acetate. Epoxygenase inhibition using a non-selective inhibitor SKF525A or a selective CYP2J2 inhibitor Compound 4, inhibited E. coli particle phagocytosis, which could be specifically reversed by 11,12-EET. Moreover, epoxygenase inhibition reduced the expression of phagocytosis receptors CD11b and CD68. CD11b also mediates L. monocytogenes phagocytosis. Similar, to E. coli bioparticle phagocytosis, epoxygenase inhibition also reduced intracellular levels of L. monocytogenes, which could be reversed by co-incubation with 11,12-EET. Disrupted bacterial clearance is a hallmark of Crohn's disease. Unlike macrophages from control donors, macrophages from Crohn's disease patients showed no induction of CYP2J2 in response to E. coli. These results demonstrate that CYP2J2 mediates bacterial phagocytosis in macrophages, and implicates a defect in the CYP2J2 pathway may regulate bacterial clearance in Crohn's disease.
Electrochemiluminescence assays for insulin and glutamic acid decarboxylase autoantibodies improve prediction of type 1 diabetes risk.

We recently developed new electrochemiluminescence (ECL) insulin autoantibody (IAA) and glutamic acid decarboxylase 65 autoantibody (GADA) assays that discriminate high-affinity, high-risk diabetes-specific autoantibodies from low-affinity, low-risk islet autoantibodies (iAbs) detected by radioassay (RAD). Here, we report a further validation of the ECL-IAA and -GADA assays in 3,484 TrialNet study participants. The ECL assay and RAD were congruent in those with prediabetes and in subjects with multiple autoantibodies, but only 24% (P<0.0001) of single RAD-IAA-positive and 46% (P<0.0001) of single RAD-GADA-positive were confirmed by the ECL-IAA and -GADA assays, respectively. During a follow-up (mean, 2.4 years), 51% of RAD-IAA-positive and 63% of RAD-GADA-positive subjects not confirmed by ECL became iAb negative, compared with only 17% of RAD-IAA-positive (P<0.0001) and 15% of RAD-GADA-positive (P<0.0001) subjects confirmed by ECL assays. Among subjects with multiple iAbs, diabetes-free survival was significantly shorter if IAA or GADA was positive by ECL and negative by RAD than if IAA or GADA was negative by ECL and positive by RAD (P<0.019 and P<0.0001, respectively). Both positive and negative predictive values in terms of progression to type 1 diabetes mellitus were superior for ECL-IAA and ECL-GADA, compared with RADs. The prevalence of the high-risk human leukocyte antigen-DR3/4, DQB1*0302 genotype was significantly higher in subjects with RAD-IAA or RAD-GADA confirmed by ECL. In conclusion, both ECL-IAA and -GADA are more disease-specific and better able to predict the risk of progression to type 1 diabetes mellitus than the current standard RADs.
[Histopathological diagnostic concordance in bone and soft tissue sarcomas between two comprehensive cancer centers from eastern and western Europe: a collaborative experience].

This study aims to assess the degree of concordance of histological diagnosis of bone and soft tissue sarcomas between a Comprehensive Cancer Center (CCC) of Eastern Europe - not specialized in this area of pathology - and an important CCC of Western Europe, which is one of the coordinators of a clinical reference network in sarcoma pathology. The goal is to have an overview of the sarcomatous pathology in a region of Eastern Europe and to discover diagnostic discrepancies between the two centers, while determining their cause.



The initial diagnosis was compared with the revised diagnosis on 110 specimens from 88 patients with bone or soft tissue sarcomas from East-European CCC, in a one-year period of time.



Complete diagnostic agreement was observed in 55 cases (62.5%), a partial agreement in 23 cases (26.1%) and a major disagreement in 10 cases (11.4%). Major discrepancies of the histological type was observed in only 3 cases (3.4%): one case of discordance benign/malignant and 2 cases of discordance mesenchymal/non mesenchymal. Minor histological discrepancies - not affecting the management of the patient - were observed in 18 cases (20.4%). A major discordance in grading - potentially changing the management of the patient - was noted in 7 cases (7.9%), and a minor discrepancy in 5 cases (5.7%).



Some histological types were clearly overdiagnosed, like "adult fibrosarcomas" and "malignant peripheral nerve sheet tumors" (MPNST), mostly converted after the audit into "undifferentiated spindle cell sarcomas" or other types of sarcomas. Some "unclassified" sarcomas and "undifferentiated pleomorphic sarcomas" could be re-classified with the aid of an extensive panel of antibodies. Overall, immunohistochemistry was responsible, but not in exclusivity, for half of the minor discrepancies, and for 2 out of 3 cases of major histological discrepancies. Otherwise, the main cause of discrepancies was the difficulties in the interpretation of the morphology. Molecular biology was decisive in one case. Most grading discrepancies resulted from the appreciation of the mitotic index.



The profile of the sarcomatous pathology in the northwest region of Romania does not appear to differ significantly from other parts of Europe or the world, but a prospective epidemiological study would be necessary to confirm this assessment. The expansion of immunohistochemical antibody panel, the over-specialization of pathologists and, in the future, the establishment of a national network of referral centers in sarcoma pathology, are required for a high level of histological diagnosis in Eastern Europe. A periodic external audit, continuing this trans-European collaboration between the two centers, would be beneficial for monitoring progress.
Improvement in symptoms and pulmonary function of asthmatic patients due to their treatment according to the Global Strategy for Asthma Management (GINA)

Global Initiative Strategy for Asthma Management (GINA) is poorly applied in undeveloped and developing countries. The current study examined the effects of applying GINA guidelines on treatment efficacy in asthmatic patients in Iran.



Twenty four asthmatic patients (usual care group) were treated as usual and 26 patients (intervention group) according to the GINA for 2 months. Asthma symptom score, asthma severity, frequency of symptoms/week and wheezing were recorded at the beginning (first visit), one month after treatment (second visit), and at the end of the study (third visit). Pulmonary function tests (PFTs) were performed by spirometry, and the patients' use of asthma drugs and their symptoms were evaluated, at each visit.



Asthma symptoms, frequency of symptoms/week, chest wheezing, and PFT values were significantly improved in the intervention group at the second and third visits compared to first visit (p < 0.001 for all measures). In addition, exercise induced cough and wheeze were significant improved in the third visit compared to the second visit in this group (p < 0.01 for both measures). In the second and third visits all symptoms were significantly lower, and PFT values higher, in the intervention group compared to the usual care group (p < 0.005 to p < 0.001). In the usual care group, there were only small improvements in some parameters in just the second visit (p < 0.01 for all measures). The use of asthma drugs was unchanged in the usual care group and significantly reduced in the intervention group (p < 0.01) by the end of the study.



Adoption of GINA guidelines improves asthma symptoms and pulmonary function in asthmatic patients in Iran.
Potential cardiac arrest – an observational study of pre-hospital medical response

A previous study showed that Norwegian GPs on call attended around 40% of out-of-hospital medical emergencies. We wanted to investigate the alarms of prehospital medical resources and the doctors' responses in situations of potential cardiac arrests.



A three-month prospective data collection was undertaken from three emergency medical communication centres, covering a population of 816,000 residents. From all emergency medical events, a sub-group of patients who received resuscitation, or who were later pronounced dead at site, was selected for further analysis.



5,105 medical emergencies involving 5,180 patients were included, of which 193 met the inclusion criteria. The GP on call was alarmed in 59 %, and an anaesthesiologist in 43 % of the cases. When alarmed, a GP attended in 84 % and an anaesthesiologist in 87 % of the cases. Among the patients who died, the GP on call was alarmed most frequently.



Events involving patients in need of resuscitation are rare, but medical response in the form of the attendance of prehospital personnel is significant. Norwegian GPs have a higher call-out rate for patients in severe situations where resuscitation was an option of treatment, compared with other "red-response" situations.  This study investigates alarms of and call-outs among GPs and anaesthesiologists on call, in the most acute clinical situations: Medical emergencies involving patients in need of resuscitation were rare. The health care contribution by pre-hospital personnel being called out was significant. Compared with other acute situations, the GP had a higher attendance rate to patients in life-threatening situations.
Quantitative and qualitative evaluation tool in planning stroke treatment strategies: the “Safe implementation of treatments in stroke Monitoring Study (SITS MOST)” registry

A decade ago, stroke was the first leading cause of morbidity and mortality in Croatia. Nowadays, we record reduction in stroke incidence, as well as stroke consequences—invalidity and mortality. These are due to long-term planned actions in the field of public health as well as actions performed by professional organizations. Today, we can be satisfied with improvement in that field, but there are still things we can improve, at the first place improvement of the emergency medicine network due to Croatian-specific topographical characteristics to reduce onset-to-door time. In this paper, we evaluated results from 11 Croatian hospitals in the period 11/2005–11/2012. To find out about the past and present state in applying thrombolytic therapy in Croatia and to plan further actions in light of new studies and efforts in Europe and in the world, all with the aim of improvement in stroke prevention and acute treatment resulting in reduction of stroke morbidity, mortality and symptomatic intracerebral hemorrhage as well as better functional outcome. Our results have shown that we improved stroke treatment in the last decade, but further actions should be performed to raise public stroke awareness and to improve emergency medicine network as well as in hospital protocols.
Demo: Position Tracking for Virtual Reality Using Commodity WiFi

Today, experiencing virtual reality (VR) is a cumbersome experience which either requires dedicated infrastructure like infrared cameras to track the headset and hand-motion controllers (e.g. Oculus Rift, HTC Vive), or provides only 3-DoF (Degrees of Freedom) tracking which severely limits the user experience (e.g. Samsung Gear VR). To truly enable VR everywhere, we need position tracking to be available as a ubiquitous service. This paper demonstrates WiCapture, a novel approach which leverages commodity WiFi infrastructure, which is ubiquitous today, for tracking purposes. We prototyped WiCapture using off-the-shelf WiFi radios and demonstrated that it achieves an accuracy of 0.88 cm compared to sophisticated infrared-based tracking systems like the Oculus Rift, while providing much higher range, resistance to occlusion, ubiquity and ease of deployment.
Increasing phenotypic and genetic variations in hyperactivity/inattention problems from age 3 to 13 years: a cross-sectional twin study.

A twin design was used to examine the developmental nature of genetic, environmental, and phenotypic variations in hyperactivity and inattention problems (HIP). Mothers of 662 complete pairs of twins (273 monozygotic [MZ] pairs and 389 dizygotic [DZ] pairs) aged from 3 to 13 years (mean [SD] age = 8.3 [2.9] years) responded to the items of the HIP scale of the Strengths and Difficulties questionnaire via a telephone interview. Maximum likelihood MZ and DZ twin correlations in the total sample were 0.47 (95% CI: 0.37-0.55) and -0.01 (95% CI: -0.11-0.09). A standard univariate model incorporating age as a modifier was applied to the raw data. Results of model-fitting analyses showed that the phenotypic variation of HIP monotonically increased from age 3 to age 12 and that this increase was completely due to an increase in genetic variance, suggesting that it is genes that expand individual difference in ADHD symptoms with age during childhood. Child-specific environmental variance was constant during this age period. In terms of relative influences, total genetic factors increased from 33% (95% CI: 27-44%) at age 3 to 51% (95% CI: 28-71%) at age 13 and this increase was accompanied by a decrease in relative influences of child-specific environmental factors from 67% (95% CI: 56-73%) at age 3 to 49% (95% CI: 29-72%) at age 13. These estimates of genetic influences were somewhat lower than those found in most twin studies of ADHD symptoms. However, the increasing trend of genetic influences with age during childhood was consistent with the results of a recent meta-analysis of ADHD symptoms.
Meat and fat intake and pancreatic cancer risk in the Netherlands Cohort Study.

Meat contains numerous carcinogens, such as heterocyclic amines, polycyclic aromatic hydrocarbons, and N-nitroso compounds, which can be derived either from natural food or during the process of food preparation. These carcinogens may increase pancreatic cancer risk. Furthermore, studies in animals showed that polyunsaturated fatty acids, especially linoleic acid, increase pancreatic cancer risk. We examined prospectively the relation between pancreatic cancer risk and intake of fresh meat, processed meat, fish, eggs, total fat, and different types of fat. The Netherlands Cohort Study consisted of 120,852 men and women who completed a baseline questionnaire in 1986. After 13.3 years of follow-up, 350 pancreatic cancer cases (66% microscopically confirmed) were available for analysis. A validated 150-item food-frequency questionnaire was used to calculate intake of fresh meat, processed meat, fish, eggs, fat and different types of fat. No association was found when examining the association between intake of fresh meat, other types of meat, fish, eggs, dietary intake of total fat and different types of fat and risk of pancreatic cancer. It is important for future studies to investigate the relation between different meat-cooking methods and pancreatic cancer.
Executive Functioning Following Mild Closed Head Injury

This study was aimed to identify impaired attentional components in mild CHI patients. The CHI features taken into account were age (< or = 30 vs. > 30 years), loss of consciousness (yes vs. no), and time after injury (few days vs. some months). The groups tested were composed of 26 patients and 26 controls (matched for age, sex and education). Experiment 1 used a dual-task paradigm (Umiltà et al., 1992), which taps executive functions. The double task-single task difference was greater for the CHI group, but only for patients older than 30 years and/or with consciousness loss. Two years after injury, some of these patients were retested: The results showed that this deficit was still present. Experiment 2 studied visual selective attention using the Navon (1977) paradigm. In this case, there were no differences between patients and controls. The results are discussed with reference to the anterior/posterior attention systems.
