Modernizing National Numbering Plan on NGN Platform - Hungarian Case Study

The intensive technological development of the last years brought the overall acceptance of an IP based network and services vision based on the NGN. The realization of the NGN vision, the decision on the migration to NGN sets regulatory tasks, especially in the area of numbering and addressing. The utilization of the opportunities provided by the NGN platform requires the use of IP addresses and names in the core network, the role of the E.164 numbers is taken over by IP addresses. However in case of voice services the identification of end-user access points will remain by the use of E.164 numbers. Migration to NGN doesn't require directly the change of the subscribers' phone number; however the NGN enables among others the implementation of national number portability for fixed telephone service. The opportunities can be realized by using uniform domestic number length and dialling method, practically closed numbering. The introduction of a 9-digit uniform, closed domestic numbering provides a consistent solution for the deficiencies of the present Hungarian numbering plan, too. Recently it can be reached in single step so that the present 9-digit domestic numbers and the short codes remain unchanged, the 8-digit domestic numbers are completed to 9-digit by the insertion of an appropriate digit, as well as the present and new numbering schemes can be in operation simultaneously. --

Relationship of circulating hyaluronic Acid levels to disease control in asthma and asthmatic pregnancy.

Uncontrolled asthma is a risk factor for pregnancy-related complications. Hyaluronic acid (HA), a potential peripheral blood marker of tissue fibrosis in various diseases, promotes eosinophil survival and plays a role in asthmatic airway inflammation as well as in physiological processes necessary to maintain normal pregnancy; however the level of circulating HA in asthma and asthmatic pregnancy is unknown. We investigated HA levels in asthmatic patients (N = 52; asthmatic pregnant (AP) N = 16; asthmatic non-pregnant (ANP) N = 36) and tested their relationship to asthma control. Serum HA level was lower in AP than in ANP patients (27 [24.7-31.55] vs. 37.4 [30.1-66.55] ng/mL, p = 0.006); the difference attenuated to a trend after its adjustment for patients' age (p = 0.056). HA levels and airway resistance were positively (r = 0.467, p = 0.004), HA levels and Asthma Control Test (ACT) total score inversely (r = -0.437, p = 0.01) associated in ANP patients; these relationships remained significant even after their adjustments for age. The potential value of HA in the determination of asthma control was analyzed using ROC analysis which revealed that HA values discriminate patients with ACT total score >/=20 (controlled patients) and <20 (uncontrolled patients) with a 0.826 efficacy (AUC, 95% CI: 0.69-0.97, p = 0.001) when 37.4 ng/mL is used as cut-off value in ANP group, and with 0.78 efficacy (AUC, 95% CI: 0.65-0.92, p = 0.0009) in the whole asthmatic cohort. In conclusion circulating HA might be a marker of asthma control, as it correlates with airway resistance and has good sensitivity in the detection of impaired asthma control. Decrease of HA level in pregnancy may be the consequence of pregnancy induced immune tolerance

Comparison of hemodynamic, biochemical and hematological parameters of healthy pregnant women in the third trimester of pregnancy and the active labor phase

<p>Abstract</p> <p>Background</p> <p>Pregnancy is accompanied by several hemodynamic, biochemical and hematological changes which revert to normal values after labor. The mean values of these parameters have been reported for developed countries, but not for Mexican women. Furthermore, labor constitutes a stress situation, in which these factors may be altered. It is known that serologic increase of heat shock protein (Hsp) 70 is associated with abnormal pregnancies, presenting very low level in normal pregnant women. Nevertheless, there are no studies where these measurements are compared in healthy pregnant women at their third trimester of pregnancy (3TP) and the active labor phase (ActLP).</p> <p>Methods</p> <p>Seventy five healthy Mexican pregnant women were included. Hemodynamic, biochemical and hematological parameters were obtained in all cases, and serum Hsp70 levels were measured in a sample of 15 women at 3TP and at ActLP.</p> <p>Results</p> <p>Significant differences were found in most analysis performed and in Hsp70 concentration at 3TP as compared to ActLP, however all were within normal range in both conditions, supporting that only in pathological pregnancies Hsp70 is drastically increased.</p> <p>Conclusion</p> <p>Results obtained indicate that 3TP and ActLP have clinical similarities in normal pregnancies, therefore if abnormalities are found during 3TP, precautions should be taken before ActLP.</p

Transcriptional Evidence for the Role of Chronic Venlafaxine Treatment in Neurotrophic Signaling and Neuroplasticity Including also Glutatmatergic- and Insulin-Mediated Neuronal Processes.

OBJECTIVES: Venlafaxine (VLX), a serotonine-noradrenaline reuptake inhibitor, is one of the most commonly used antidepressant drugs in clinical practice for the treatment of major depressive disorder (MDD). Despite being more potent than its predecessors, similarly to them, the therapeutical effect of VLX is visible only 3-4 weeks after the beginning of treatment. Furthermore, recent papers show that antidepressants, including also VLX, enhance the motor recovery after stroke even in non depressed persons. In the present, transcriptomic-based study we looked for changes in gene expressions after a long-term VLX administration. METHODS: Osmotic minipumps were implanted subcutaneously into Dark Agouti rats providing a continuous (40 mg/kg/day) VLX delivery for three weeks. Frontal regions of the cerebral cortex were isolated and analyzed using Illumina bead arrays to detect genes showing significant chances in expression. Gene set enrichment analysis was performed to identify specific regulatory networks significantly affected by long term VLX treatment. RESULTS: Chronic VLX administration may have an effect on neurotransmitter release via the regulation of genes involved in vesicular exocytosis and receptor endocytosis (such as Kif proteins, Myo5a, Sv2b, Syn2 or Synj2). Simultaneously, VLX activated the expression of genes involved in neurotrophic signaling (Ntrk2, Ntrk3), glutamatergic transmission (Gria3, Grin2b and Grin2a), neuroplasticity (Camk2g/b, Cd47), synaptogenesis (Epha5a, Gad2) and cognitive processes (Clstn2). Interestingly, VLX increased the expression of genes involved in mitochondrial antioxidant activity (Bcl2 and Prdx1). Additionally, VLX administration also modulated genes related to insulin signaling pathway (Negr1, Ppp3r1, Slc2a4 and Enpp1), a mechanism that has recently been linked to neuroprotection, learning and memory. CONCLUSIONS: Our results strongly suggest that chronic VLX treatment improves functional reorganization and brain plasticity by influencing gene expression in regulatory networks of motor cortical areas. These results are consonant with the synaptic (network) hypothesis of depression and antidepressant-induced motor recovery after stroke

Clinical Effectiveness of Budesonide/Formoterol Fumarate Easyhaler(A (R)) for Patients with Poorly Controlled Obstructive Airway Disease: a Real-World Study of Patient-Reported Outcomes

The effectiveness of inhaled therapies can be influenced by many factors, including the type of inhaler, which may have clinical implications. We report a real-world, multicenter, open-label, non-randomized, non-interventional study conducted by 200 pulmonologists across 200 centers in Hungary. The effectiveness of budesonide/formoterol inhalation therapy in daily clinical practice, delivered via the Bufomix Easyhaler(A (R)), was evaluated in patients with asthma, chronic obstructive pulmonary disease (COPD) and asthma-COPD overlap (ACO). Effectiveness was assessed after 12 weeks of treatment by spirometry, the Asthma Control Test, mini-Asthma Quality of Life Questionnaire, COPD Assessment Test and modified Medical Research Council dyspnea scale. Patient satisfaction with the Bufomix Easyhaler(A (R)) and physicians' assessments (ease of use and time taken to learn the technique) were also assessed. A total of 1498 patients with obstructive airway disease were evaluated (asthma: n = 621; COPD: n = 778; ACO: n = 99), of whom 455 (30.4%) were newly diagnosed inhaler-na 0.002) were reported after 12 weeks of Bufomix Easyhaler(A (R)) use. Improvements were observed in both inhaler-na 90.0% of physicians described the Bufomix Easyhaler(A (R)) as easy to teach; 73.8% and 98.9% of patients learned the technique within 5 and 10 min of teaching, respectively. Twelve weeks' treatment with the Bufomix Easyhaler(A (R)) resulted in significant improvements in disease control and quality of life. The Bufomix Easyhaler(A (R)) was considered easy to use, and most patients were satisfied with the inhaler. Results confirm the real-world effectiveness of the Bufomix Easyhaler(A (R)) in the treatment of adult outpatients with obstructive airway disease. Orion Corp., Orion Pharma

Evaluation of a Partial Genome Screening of Two Asthma Susceptibility Regions Using Bayesian Network Based Bayesian Multilevel Analysis of Relevance

Genetic studies indicate high number of potential factors related to asthma. Based on earlier linkage analyses we selected the 11q13 and 14q22 asthma susceptibility regions, for which we designed a partial genome screening study using 145 SNPs in 1201 individuals (436 asthmatic children and 765 controls). The results were evaluated with traditional frequentist methods and we applied a new statistical method, called Bayesian network based Bayesian multilevel analysis of relevance (BN-BMLA). This method uses Bayesian network representation to provide detailed characterization of the relevance of factors, such as joint significance, the type of dependency, and multi-target aspects. We estimated posteriors for these relations within the Bayesian statistical framework, in order to estimate the posteriors whether a variable is directly relevant or its association is only mediated. With frequentist methods one SNP (rs3751464 in the FRMD6 gene) provided evidence for an association with asthma (OR = 1.43(1.2–1.8); p = 3×10−4). The possible role of the FRMD6 gene in asthma was also confirmed in an animal model and human asthmatics. In the BN-BMLA analysis altogether 5 SNPs in 4 genes were found relevant in connection with asthma phenotype: PRPF19 on chromosome 11, and FRMD6, PTGER2 and PTGDR on chromosome 14. In a subsequent step a partial dataset containing rhinitis and further clinical parameters was used, which allowed the analysis of relevance of SNPs for asthma and multiple targets. These analyses suggested that SNPs in the AHNAK and MS4A2 genes were indirectly associated with asthma. This paper indicates that BN-BMLA explores the relevant factors more comprehensively than traditional statistical methods and extends the scope of strong relevance based methods to include partial relevance, global characterization of relevance and multi-target relevance

Valuation of pemphigus vulgaris and pemphigus foliaceus health states: a convenience sample experiment

Item does not contain fulltextBACKGROUND: Health-related quality of life (HRQoL) in pemphigus has been widely investigated; nevertheless, utility values for economic evaluations are still lacking. OBJECTIVES: To estimate health utilities for hypothetical pemphigus vulgaris (PV) and pemphigus foliaceus (PF) health states in a general population sample. METHODS: Three health states (uncontrolled PV, uncontrolled PF and controlled pemphigus) were developed based on a systematic literature review of HRQoL studies in pemphigus. Utilities were obtained from a convenience sample of 108 adults using a visual analogue scale (VAS) and 10-year time trade-off (TTO). Lead-time TTO was applied for health states regarded as worse than dead with a lead time to disease time ratio of 1 : 1. Results : The mean VAS utility scores for PV, PF and controlled pemphigus were 0.25 +/- 0.15, 0.37 +/- 0.17 and 0.63 +/- 0.16, respectively. Corresponding TTO utilities were as follows: 0.34 +/- 0.38, 0.51 +/- 0.32 and 0.75 +/- 0.31. Overall, 14% and 6% judged PV and PF as being worse than dead. For both VAS and TTO values, significant differences were observed between all health states (P < 0.001). VAS utilities were rated significantly lower compared with TTO in each health state (P < 0.001). CONCLUSIONS: This is the first study that reports health utility values for PV and PF. Successful treatment of pemphigus might result in significant utility gain (0.24-0.41). These empirical findings with respect to three health states in pemphigus may serve as anchor points for further utility studies and cost-effectiveness analyses
