HOUSE OWNER'S ECHOING SYSTEM FOR SECURE PROTECTION

Within this paper it proposes a stride of utilizing ZigBee wireless transmission to watch the potential house invasion its dimensions are the hyperlink Quality Indicator (LQI) between your terminals of Coordinator and also the Finish-Devices and monitor the LQI variations to find out can there be any invasion. ZigBee Finish-System is setup in the door and across from it's the ZigBee Coordinator their distance is restricted within 75 meters. Within this paper we studied the LQI variations in three environments. In the test outcomes of these 3 environments it figured that the LQI value will not have apparent variation and just whether it had door open or close the LQI might have significant varied. If somebody goes into the area the ability between your terminal transceivers will induce some variations and out of this power variation to find out can there be any invasion. The individual from outdoors opens the classroom door goes into the classroom after which walks go through the mid-place between Coordinator and also the Finish-Device terminals after which walks outdoors and closes the doorway. The essential idea is always to rebuild a packet's path by the assistance of the area packets every single hop. So that you can decide if a packet is at its forwarders' stable periods, we utilize the packet generation some time to parents change counter in each and every packet

Bone fractures in patients using tapentadol or oxycodone: an exploratory US claims database study

Aim: To explore fracture outcomes with tapentadol or oxycodone, two opioids with differing mechanisms of action. Materials & methods: Retrospective cohort pilot study, using MarketScan® Commercial and Medicare Supplemental claims databases, on patients with postoperative pain, back pain, or osteoarthritis and ≥1 claim for tapentadol (n = 16,457), oxycodone (n = 1,356,920), or both (n = 15,893) between June 2009 and December 2015. Results: During 266,826 and 9,007,889 days of tapentadol and oxycodone treatment, patients evidenced 1080 and 72,275 fractures, respectively. Fracture rates per treatment-year were 1.512 for tapentadol and 3.013 for oxycodone. Conclusion: Examination of administrative claims has inherent limitations, but this exploratory analysis indicates a lower fracture rate with tapentadol than oxycodone in the analyzed dataset, which needs confirmation by further clinical trials

Quality of life and functional outcomes with tapentadol prolonged release in chronic musculoskeletal pain: post hoc analysis

Aims: To investigate quality of life (QOL) and functionality changes in chronic pain during tapentadol prolonged release (PR) treatment. Patients & methods: Post hoc analysis of data from three Phase III trials in patients with osteoarthritis knee pain or low back pain. QOL and functionality changes were assessed by SF-36 scores. Results: All SF-36 subdomain scores improved progressively to week 3 of tapentadol titration and were sustained during 12-week maintenance treatment. Improvements in SF-36 scores were similar between tapentadol dose groups (e.g., 200 to <300 mg vs >= 500 mg), with no greater effect from higher doses. QOL and functionality improvements were consistently greater with tapentadol PR than oxycodone controlled release. Conclusion: Tapentadol PR provides consistent, clinically relevant improvements in QOL and functionality in chronic pain

Therapeutic Targets for Heart Failure Identified Using Proteomics and Mendelian Randomization

Background: Heart failure (HF) is a highly prevalent disorder for which disease mechanisms are incompletely understood. The discovery of disease-associated proteins with causal genetic evidence provides an opportunity to identify new therapeutic targets. Methods: We investigated the observational and causal associations of 90 cardiovascular proteins, which were measured using affinity-based proteomic assays. First, we estimated the associations of 90 cardiovascular proteins with incident heart failure by means of a fixed-effect meta-analysis of four population-based studies, comprising a total of 3,019 participants with 732 HF events. The causal effects of HF-associated proteins were then investigated by Mendelian randomization (MR), using cis-protein quantitative loci genetic instruments identified from genome-wide association studies (GWAS) in over 30,000 individuals. To improve the precision of causal estimates, we implemented an MR model that accounted for linkage disequilibrium between instruments and tested the robustness of causal estimates through a multiverse sensitivity analysis that included up to 120 combinations of instrument selection parameters and MR models per protein. The druggability of candidate proteins was surveyed, and mechanism of action and potential on-target side effects were explored with cross-trait MR analysis. Results: 44/90 proteins were positively associated with risk of incident HF (P < 6.0 x 10-4). Among these, eight proteins had evidence of a causal association with HF that was robust to multiverse sensitivity analysis: higher CSF-1 (macrophage colony-stimulating factor 1), Gal-3 (galectin-3) and KIM-1 (kidney injury molecule 1) were positively associated with risk of HF, whereas higher ADM (adrenomedullin), CHI3L1 (chitinase-3-like protein 1), CTSL1 (cathepsin L1), FGF-23 (fibroblast growth factor 23) and MMP-12 (Matrix metalloproteinase-12) were protective. Therapeutics targeting ADM and Gal-3 are currently under evaluation in clinical trials, and all the remaining proteins were considered druggable, except KIM-1. Conclusions: We identified 44 circulating proteins that were associated with incident HF, of which eight showed evidence of a causal relationship and seven were druggable, including adrenomedullin which represents a particularly promising drug target. Our approach demonstrates a tractable roadmap for the triangulation of population genomic and proteomic data for the prioritization of therapeutic targets for complex human diseases

Effects of danicamtiv, a novel cardiac myosin activator, in heart failure with reduced ejection fraction: experimental data and clinical results from a phase 2a trial

Aims: Both left ventricular (LV) and left atrial (LA) dysfunction and remodelling contribute to adverse outcomes in heart failure with reduced ejection fraction (HFrEF). Danicamtiv is a novel, cardiac myosin activator that enhances cardiomyocyte contraction. Methods and results: We studied the effects of danicamtiv on LV and LA function in non‐clinical studies (ex vivo : skinned muscle fibres and myofibrils; in vivo : dogs with heart failure) and in a randomized, double‐blind, single‐ and multiple‐dose phase 2a trial in patients with stable HFrEF (placebo, n = 10; danicamtiv, n = 30; 50–100 mg twice daily for 7 days). Danicamtiv increased ATPase activity and calcium sensitivity in LV and LA myofibrils/muscle fibres. In dogs with heart failure, danicamtiv improved LV stroke volume (+10.6 mL, P &lt; 0.05) and LA emptying fraction (+10.7%, P &lt; 0.05). In patients with HFrEF (mean age 60 years, 25% women, ischaemic heart disease 48%, mean LV ejection fraction 32%), treatment‐emergent adverse events, mostly mild, were reported in 17 patients (57%) receiving danicamtiv and 4 patients (40%) receiving placebo. Danicamtiv (at plasma concentrations ≥2000 ng/mL) increased stroke volume (up to +7.8 mL, P &lt; 0.01), improved global longitudinal (up to −1.0%, P &lt; 0.05) and circumferential strain (up to −3.3%, P &lt; 0.01), decreased LA minimal volume index (up to −2.4 mL/m2, P &lt; 0.01) and increased LA function index (up to 6.1, P &lt; 0.01), when compared with placebo. Conclusions: Danicamtiv was well tolerated and improved LV systolic function in patients with HFrEF. A marked improvement in LA volume and function was also observed in patients with HFrEF, consistent with pre‐clinical findings of direct activation of LA contractility

Haemodynamic effects of the nitroxyl donor cimlanod (BMS-986231) in chronic heart failure: a randomized trial

Aims Nitroxyl provokes vasodilatation and inotropic and lusitropic effects in animals via post-translational modification of thiols. We aimed to compare effects of the nitroxyl donor cimlanod (BMS-986231) with those of nitroglycerin (NTG) or placebo on cardiac function in patients with chronic heart failure with reduced ejection fraction (HFrEF). Methods and results In a randomized, multicentre, double-blind, crossover trial, 45 patients with stable HFrEF were given a 5 h intravenous infusion of cimlanod, NTG, or placebo on separate days. Echocardiograms were done at the start and end of each infusion period and read in a core laboratory. The primary endpoint was stroke volume index derived from the left ventricular outflow tract at the end of each infusion period. Stroke volume index with placebo was 30 ± 7 mL/m2 and was lower with cimlanod (29 ± 9 mL/m2; P = 0.03) and NTG (28 ± 8 mL/m2; P = 0.02). Transmitral E-wave Doppler velocity on cimlanod or NTG was lower than on placebo and, consequently, E/e′ (P = 0.006) and E/A ratio (P = 0.003) were also lower. NTG had similar effects to cimlanod on these measurements. Blood pressure reduction was similar with cimlanod and NTG and greater than with placebo. Conclusion In patients with chronic HFrEF, the haemodynamic effects of cimlanod and NTG are similar. The effects of cimlanod may be explained by venodilatation and preload reduction without additional inotropic or lusitropic effects. Ongoing trials of cimlanod will further define its potential role in the treatment of heart failure

Endothelial Contributions to Zebrafish Heart Regeneration

Studies over the past two decades have shown heart regeneration in zebrafish to be a dynamic process, choreographed by multiple cell types. In particular, recent work has identified revascularization of the wound to be a sentinel event during heart regeneration. The cardiac endothelium has emerged as a key orchestrator of heart regeneration, influencing cardiomyocyte hyperplasia and tissue morphogenesis. Here, we review how the coronary vasculature regenerates after injury, how signaling pathways link the cardiac endothelium to heart regeneration, and how understanding these signaling dynamics can lead to targeted therapies for heart regeneration

Severe chronic low back pain: patient journey from onset of symptoms to strong opioid treatments in Europe

Aim: We report the first patient roadmap in severe chronic low back pain (cLBP) in Europe, assessing the views of cLBP patients and general practitioners (GPs) who treat cLBP with regard to current cLBP management. Methodology: Patient journey mapping was conducted in four European countries to assess the views of cLBP patients (n = 20) and GPs (n = 40). Results: Four broad phases of cLBP, subdivided into eight individual steps, were identified as part of the patient journey, showing a disconnect between patients' and physicians' treatment goals, and expectations regarding pain relief levels for some patients. Conclusion: Improved communication, with greater involvement of patients in multimodal management decisions, might benefit the GP-patient relationship and overall outcomes for cLBP patients
