The impact of a diagnosis of fibromyalgia on health care resource use by primary care patients in the UK: an observational study based on clinical practice.

OBJECTIVE To investigate the impact of a diagnosis of fibromyalgia (FM) in clinical practice on health care resource use in the UK. METHODS Rates of visits, prescriptions, referral, and diagnostic testing were estimated in patients who had been diagnosed as having FM between 1998 and March 2003 in UK primary care and compared with those in matched controls. Rates were calculated in 6-month intervals from 10 years before until 4 years after the FM diagnosis. RESULTS Patients (2260) were newly diagnosed as having FM; 81.3% were women. Their mean age was 49 years. FM patients had considerably higher rates of visits, prescriptions, and testing from at least 10 years prior to diagnosis compared with controls. By the time of diagnosis, FM patients had 25 visits and 11 prescriptions per year compared with 12 visits and 4.5 prescriptions per year in controls. Visit rates were highest for depression, followed by fatigue, chest pain, headache, and sleep disturbance. Following diagnosis, visits for most symptoms and health care use markers declined, but within 2-3 years, most visits rose to levels at or higher than those at diagnosis. CONCLUSION Primary care patients who had been diagnosed as having FM reported higher rates of illness and health care resource use for at least 10 years prior to their diagnosis, which suggests that illness behavior may play a role. Being diagnosed as having FM may help patients cope with some symptoms, but the diagnosis has a limited impact on health care resource use in the longer term, possibly because there is little effective treatment.
Patient-Driven Second Opinions in Oncology: A Systematic Review.

BACKGROUND Although patient-driven second opinions are increasingly sought in oncology, the desirability of this trend remains unknown. Therefore, this systematic review assesses evidence on the motivation for and frequency of requests for second opinions and examines how they evolve and their consequences for oncological practice. MATERIALS AND METHODS Relevant databases were sought using the terms "cancer," "second opinion," and "self-initiated. " Included were peer-reviewed articles that reported on patient-initiated second opinions within oncology. Selection, data extraction, and quality assessment were performed and discussed by two researchers. RESULTS Of the 25 included studies, the methodological designs were qualitative (n = 4), mixed (n = 1), or quantitative (n = 20). Study quality was rated high for 10 studies, moderate for eight, and low for seven studies. Reported rates of second opinion seeking ranged from 1%-88%. Higher education was most consistently related to seeking a second opinion. Patients' primary motivations were a perceived need for certainty or confirmation, a lack of trust, dissatisfaction with communication, and/or a need for more (personalized) information. Reported rates of diagnostic or therapeutic discrepancies between the first and second opinions ranged from 2%-51%. DISCUSSION Additional studies are required to further examine the medical, practical, and psychological consequences of second opinions for patients and oncologists. Future studies could compare the potential advantages and disadvantages of second opinion seeking, and might offer guidance to patients and physicians to better facilitate the second opinion process. Some practical recommendations are provided for oncologists to optimally discuss and conduct second opinions with their patients. The Oncologist 2017;22:1197-1211 IMPLICATIONS FOR PRACTICE: Although cancer patients increasingly seek a second opinion, the benefits of this process remain unclear. Results of this systematic review suggest that the available studies on this topic are highly variable in both methodology and quality. Moreover, reported rates for a second opinion (1%-88%) as well as for disagreement between the first and second opinion (2%-51%) range widely. The primary motivations of patients are a need for certainty, lack of trust, dissatisfaction with communication, and/or a need for more (personalized) information. Additional research should evaluate how unnecessary second opinions might be avoided. Practical suggestions are provided for oncologists to optimize second opinions.
Vaccinia virions lacking core protein VP8 are deficient in early transcription

When synthesis of the 25-kDa vaccinia virus core protein VP8 is repressed, mature virus particles of normal appearance are produced to approximately 80% of wild-type levels but these particles are over 100-fold less infectious than wild-type particles (D. Wilcock and G. L. Smith, Virology 202:294-304, 1994). Here we show that virions which lack VP8 can bind to and enter cells but the levels of steady-state RNA are greatly reduced in comparison with those for wild-type infections. In vitro assays using permeabilized virions demonstrated that VP8-deficient virions had drastically reduced rates of transcription (RNA synthesis was decreased by 80 to 96%) and that the extrusion of RNA transcripts from these virions was also decreased. Low concentrations of sodium deoxycholate extracted proteins more efficiently from VP8-deficient virions than from wild-type virions. The increased fragility of VP8-deficient virions and their slower RNA extrusion rates suggest that VP8 may be required for the correct formation of the core. Virions which lack VP8 were shown to contain a full complement of transcription enzymes, and soluble extracts from these virions were active in transcription assays using either single-stranded M13 DNA or exogenous plasmid template containing a vaccinia virus early promoter. Thus, the defect in transcription is due not to a lack of specific transcriptional enzymes within virions but rather to the inability of these enzymes to efficiently transcribe the DNA genome packaged within VP8-deficient virions. These results suggest that VP8 is required for the correct packaging of the viral DNA genome and/or for the efficient transcription of packaged virion DNA, which has a higher degree of structural complexity than plasmid templates. Possible roles for VP8 in these processes are discussed.
Defense against PUEA and SSDF attacks in cognitive radio networks

Secondary users can utilize the spectrum in the absence of primary users (PU) in cognitive radio networks (CRN). Hence there is a need to sense the spectrum perfectly. Because of hidden node problem, the sensing information given by single SU may not be reliable information. In cooperative spectrum sensing, local sensing is performed by number of SUs and report their local decisions to fusion center (FC). FC combines these local decisions using fusion rules and takes accurate final decision regarding the presence or absence of PU. Primary user emulation attack (PUEA) and spectrum sensing data falsification attack (SSDF) are the two common threats to CRNs. In this paper hard decision fusion rules are applied such as AND, OR and K out of N rules in the presence of PUEA attacker to evaluate the performance of CRN. Also to mitigate the effect of SSDF attack, a novel reputation based method is proposed and these fusion rules are used to make final decision. Energy detection technique is used for local sensing. Simulation results show that the proposed method yields better performance in the presence of PUEA and SSDF attacks.
13C isotopomer analysis of glucose and alanine metabolism reveals cytosolic pyruvate compartmentation as part of energy metabolism in astrocytes

After incubation of glial cells with both 13C‐labeled and unlabeled glucose and alanine, 13C isotopomer analysis indicates two cytosolic pyruvate compartments in astrocytes. One pyruvate pool is in an exchange equilibrium with exogenous alanine and preferentially synthesizes releasable lactate. The second pyruvate pool, which is of glycolytic origin, is more closely related to mitochondrial pyruvate, which is oxidized via tri carbonic acid (TCA) cycle activity. In order to provide 2‐oxoglutarate as a substrate for cytosolic alanine aminotransferase, glycolytic activity is increased in the presence of exogenous alanine. Furthermore, in the presence of alanine, glutamate is accumulated in astrocytes without subsequent glutamine synthesis. We suggest that the conversion of alanine to releasable lactate proceeds at the expense of flux of glycolytic pyruvate through lactate dehydrogenase, which is used for ammonia fixation by alanine synthesis in the cytosol and for mitochondrial TCA cycle activity. In addition, an intracellular trafficking occurs between cytosol and mitochondria, by which these two cytosolic pyruvate pools are partly connected. Thus, exogenous alanine modifies astrocytic glucose metabolism for the synthesis of releasable lactate disconnected from glycolysis. The data are discussed in terms of astrocytic energy metabolism and the metabolic trafficking via a putative alanine‐lactate shuttle between astrocytes and neurons.

Adjuvant chemotherapy for the treatment of intracranial ependymoma of childhood

Current treatment for childhood intracranial ependymomas with surgery and radiation therapy (RT) yields 5‐year survival rates ranging from 50‐70% after complete resection to 0‐30% after incomplete surgical resection. The role of chemotherapy in the treatment of ependymoma has not been established. In this pilot study, children with newly diagnosed intracranial ependymoma were treated with RT and chemotherapy using agents comparable to those found to be active in the treatment of intracranial ependymoma in infants.
Randomized Controlled Trial of Acceptance and Commitment Therapy for Distress and Impairment in OEF/OIF/OND Veterans

Objective: Acceptance and commitment therapy (ACT) is a widely utilized psychotherapeutic approach, but randomized, controlled studies are lacking in veterans. This study evaluated the efficacy of ACT for emotional distress among veterans of the conflicts in Iraq and Afghanistan. Method: One hundred sixty veterans (80% male, Mage = 34 years) with anxiety or depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) were randomized to ACT or present-centered therapy (PCT) and assessed before, during, and after treatment and during 3- to 12-month follow-up. The primary outcome was general distress as measured by the Brief Symptom Inventory–18 Global Severity Index. Additional outcomes included symptomatology, disability, quality of life, acceptability, and satisfaction. Results: There was improvement following treatment in the whole sample across a variety of measures, including general distress (d = 0.74, 95% confidence interval [CI: 0.52, 0.96]) and functioning (d = 0.71, 95% CI [0.50, 0.93]) and moderate to high levels of satisfaction with treatment. Response to the 2 interventions did not differ on the primary outcome or most secondary outcomes, although ACT led to greater improvement in insomnia than did PCT (ds = 0.63 and 0.08, respectively). Treatment dropout did not differ by condition but was high (41.9%). Conclusions: ACT’s efficacy in this group was modest and generally did not differ from that for PCT. Additional work is needed to understand the reasons that ACT did not perform as well as predicted in this veteran sample.
Interaction network of the ribosome assembly machinery from a eukaryotic thermophile

Ribosome biogenesis in eukaryotic cells is a highly dynamic and complex process innately linked to cell proliferation. The assembly of ribosomes is driven by a myriad of biogenesis factors that shape pre‐ribosomal particles by processing and folding the ribosomal RNA and incorporating ribosomal proteins. Biochemical approaches allowed the isolation and characterization of pre‐ribosomal particles from Saccharomyces cerevisiae, which lead to a spatiotemporal map of biogenesis intermediates along the path from the nucleolus to the cytoplasm. Here, we cloned almost the entire set (∼180) of ribosome biogenesis factors from the thermophilic fungus Chaetomium thermophilum in order to perform an in‐depth analysis of their protein–protein interaction network as well as exploring the suitability of these thermostable proteins for structural studies. First, we performed a systematic screen, testing about 80 factors for crystallization and structure determination. Next, we performed a yeast 2‐hybrid analysis and tested about 32,000 binary combinations, which identified more than 1000 protein–protein contacts between the thermophilic ribosome assembly factors. To exemplary verify several of these interactions, we performed biochemical reconstitution with the focus on the interaction network between 90S pre‐ribosome factors forming the ctUTP‐A and ctUTP‐B modules, and the Brix‐domain containing assembly factors of the pre‐60S subunit. Our work provides a rich resource for biochemical reconstitution and structural analyses of the conserved ribosome assembly machinery from a eukaryotic thermophile.
Experimental oleander (Nerium oleander) intoxication in broiler chickens (Gallus gallus)

Dried leaves of oleander were orally given at a single dose of 500 mg/kg body weight to 20 clinically healthy male chickens. Clinical signs of toxicosis began to appear about 1 h after receiving the oleander and included hypersalivation, vomiting, diarrhea, deep depression, and sudden death. Also, hyperemia in the combs and wattles was obviously seen. Electrocardiograms (ECG) were repeatedly recorded at 30 min intervals. ECGs findings included increasing the QRS duration in some birds and various kinds of arrhythmias. Bradycardia was the most frequently detected finding (30.43%). During necropsy, there were congestion and hemorrhages in the visceral organs particularly in heart, liver, kidney, and lung. Histopathology revealed myocardial cell necrosis with hyperemia and hemorrhage, severe diffuse pulmonary congestion and edema, severe renal congestion and hemorrhage with tubular necrosis, and coagulative necrosis of hepatocytes with hyperemia and hemorrhage. There were also congestion, mild epithelial necrosis and desquamation with infiltration of mononuclear inflammatory cells in the proventriculus of all birds. There was also mild to moderate congestion in the intestines with scattered necrosis of surface enterocytes. The lack of information about the toxicity of oleanders in poultry was the main cause for this study. The results suggest that chickens appear to respond to oleander poisoning in a manner similar to other species.
Meta‐analysis of studies with bivariate binary outcomes: a marginal beta‐binomial model approach

When conducting a meta‐analysis of studies with bivariate binary outcomes, challenges arise when the within‐study correlation and between‐study heterogeneity should be taken into account. In this paper, we propose a marginal beta‐binomial model for the meta‐analysis of studies with binary outcomes. This model is based on the composite likelihood approach and has several attractive features compared with the existing models such as bivariate generalized linear mixed model (Chu and Cole, 2006) and Sarmanov beta‐binomial model (Chen et al., 2012). The advantages of the proposed marginal model include modeling the probabilities in the original scale, not requiring any transformation of probabilities or any link function, having closed‐form expression of likelihood function, and no constraints on the correlation parameter. More importantly, because the marginal beta‐binomial model is only based on the marginal distributions, it does not suffer from potential misspecification of the joint distribution of bivariate study‐specific probabilities. Such misspecification is difficult to detect and can lead to biased inference using currents methods. We compare the performance of the marginal beta‐binomial model with the bivariate generalized linear mixed model and the Sarmanov beta‐binomial model by simulation studies. Interestingly, the results show that the marginal beta‐binomial model performs better than the Sarmanov beta‐binomial model, whether or not the true model is Sarmanov beta‐binomial, and the marginal beta‐binomial model is more robust than the bivariate generalized linear mixed model under model misspecifications. Two meta‐analyses of diagnostic accuracy studies and a meta‐analysis of case–control studies are conducted for illustration. Copyright © 2015 John Wiley & Sons, Ltd.
Structural trees for protein superfamilies

Structural trees for large protein superfamilies, such as β proteins with the aligned β sheet packing, β proteins with the orthogonal packing of α helices, two‐layer and three‐layer α/β proteins, have been constructed. The structural motifs having unique overall folds and a unique handedness are taken as root structures of the trees. The larger protein structures of each superfamily are obtained by a stepwise addition of α helices and/or β strands to the corresponding root motif, taking into account a restricted set of rules inferred from known principles of the protein structure. Among these rules, prohibition of crossing connections, attention to handedness and compactness, and a requirement for α helices to be packed in α‐helical layers and β strands in β layers are the most important. Proteins and domains whose structures can be obtained by stepwise addition of α helices and/or β strands to the same root motif can be grouped into one structural class or a superfamily. Proteins and domains found within branches of a structural tree can be grouped into subclasses or subfamilies. Levels of structural similarity between different proteins can easily be observed by visual inspection. Within one branch, protein structures having a higher position in the tree include the structures located lower. Proteins and domains of different branches have the structure located in the branching point as the common fold. Proteins 28:241–260, 1997. © 1997 Wiley‐Liss Inc.
Maintaining high moisture content of macadamia nuts-in-shell during storage induces brown centres in raw kernels.

BACKGROUND Kernel brown centres in macadamia are a defect causing internal discolouration of kernels. This study investigates the effect on the incidence of brown centres in raw kernel after maintaining high moisture content in macadamia nuts-in-shell stored at temperatures of 30°C, 35°C, 40°C and 45°C. RESULTS Brown centres of raw kernel increased with nuts-in-shell storage time and temperature when high moisture content was maintained by sealing in polyethylene bags. Almost all kernels developed the defect when kept at high moisture content for 5 days at 45°C, and 44% developed brown centres after only 2 days of storage at high moisture content at 45°C. This contrasted with only 0.76% when stored for 2 days at 45°C but allowed to dry in open-mesh bags. At storage temperatures below 45°C, there were fewer brown centres, but there were still significant differences between those stored at high moisture content and those allowed to dry (P < 0.05). CONCLUSION Maintenance of high moisture content during macadamia nuts-in-shell storage increases the incidence of brown centres in raw kernels and the defect increases with time and temperature. On-farm nuts-in-shell drying and storage practices should rapidly remove moisture to reduce losses. Ideally, nuts-in-shell should not be stored at high moisture content on-farm at temperatures over 30°C.
Particle Detection and it's Radar Application

In this paper we introduce a new detection algorithm based on Monte Carlo sampling method. The proposed method is numerical in nature. We use importance sampling to estimate unknown parameters and calculate likelihood ratio and call it particle detector (PD). This detector can be used in wide range of detection problems. We have also presented an adaptive radar detection algorithm based on our proposed particle detection scheme
Plasma Membrane Ca2+ Pump in Rat Brain

The expression at the protein level of plasma membrane calcium pump (PMCA) isoforms in rat brain was detected by new antibodies that distinguished the four gene products and their alternatively spliced variants. All four gene products were distributed throughout hippocampus, cortex, and cerebellum, but the alternate splices showed more distinct distribution patterns. The b splice of isoform 1 was not detectable in any of the brain regions, which makes it unlikely that this isoform performs an essential housekeeping role as is frequently proposed. The b splices of isoforms 3 and 4, although expressed in all three regions, showed evidence of proteolysis, which removed a portion of the carboxyl terminus. In contrast, isoform 2b retained its full length, indicating that PMCA2b is more resistant to proteolysis than the other b forms. Whereas substantial amounts of isoforms 1a, 2a, and 3a were expressed in all regions, 4a was found only in frontal cortex. The distinct patterns of expression of the PMCA isoforms in brain suggest that some of them play a special role in intracellular Ca regulation.
Use of the lung cancer–specific Quality of Life Questionnaire EORTC QLQ‐LC13 in clinical trials: A systematic review of the literature 20 years after its development

The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire‐Lung Cancer 13 (QLQ‐LC13) covers 13 typical symptoms of lung cancer patients and was the first module developed in conjunction with the EORTC core quality‐of‐life (QL) questionnaire. This review investigates how the module has been used and reported in cancer clinical trials in the 20 years since its publication. Thirty‐six databases were searched with a prespecified algorithm. This search plus an additional hand search generated 770 hits, 240 of which were clinical studies. Two raters extracted data using a coding scheme. Analyses focused on the randomized controlled trials (RCTs). Of the 240 clinical studies that were identified using the LC13, 109 (45%) were RCTs. More than half of the RCTs were phase 3 trials (n = 58). Twenty RCTs considered QL as the primary endpoint, and 68 considered it as a secondary endpoint. QL results were addressed in the results section of the article (n = 89) or in the abstract (n = 92); and, in half of the articles, QL results were presented in the form of tables (n = 53) or figures (n = 43). Furthermore, QL results had an impact on the evaluation of the therapy that could be clearly demonstrated in the 47 RCTs that yielded QL differences between treatment and control groups. The EORTC QLQ‐LC13 fulfilled its mission to be used as a standard instrument in lung cancer clinical trials. An update of the LC13 is underway to keep up with new therapeutic trends and to ensure optimized and relevant QL assessment in future trials. Cancer 2015;121:4300–23. © 2015 American Cancer Society.
Balancing QoE and fairness of heterogeneous traffics based on Equivalent Rate Scaling

With great increase of mobile service in recent years, high quality of experience (QoE) is becoming a comprehensive and major goal for service provider. To unify evaluations of different services, mean opinion score (MOS) as a subjective assessment is usually adopted for accurate and convincing reflection of user perceived quality. In this paper, we consider the effect of the burst transmission of best effort (BE) traffic on the uses with real time video traffic in the same cell. We extend the rate scaling process which was initially used to shape burstiness of BE users as interference to handle the scenario that BE users act as resource competitors with video users. A power reallocation strategy between the two types of users is presented and an algorithm further improving the fairness of BE users is proposed. The simulation results demonstrate that the proposed algorithm can not only promote the QoE of both types of users, but also guarantee the fairness among users.
