This research investigates the optimization of downlink performance metrics, including spectral efficiency, data rates, and coverage, for cell-edge user equipment (UE) in Beyond 5G (B5G) networks using a hybrid relaying Cooperative Non-Orthogonal Multiple Access (CNOMA) framework.The system architecture consists of a gNodeB (gNB) located at the cell center, serving both an intra-cell cluster (ICC) near the gNB and a cell-edge cluster (CEC) positioned farther away.To address the challenges faced by UEs in these clusters, particularly random signal strength deprivation due to deep Rayleigh fading, two novel resource allocation strategies are proposed: Channel-Aware Adaptive Fair (CAAF) Power Allocation and Resource-Free Best Positioned Opportunistic Relay Selection (RFBP-ORS).The CAAF method ensures fair and dynamic power allocation by leveraging real-time channel state information (CSI), while RFBP-ORS selects the optimal relay based on resource availability and spatial positioning, thereby maintaining uninterrupted connectivity.Simulation results reveal that the proposed methodologies significantly enhance the achievable data rates by up to 140% compared to conventional CNOMA, reaching 5.8 bps/Hz at 12.5 dB SINR.They also improve energy efficiency to 1 Gb/J and achieve a 10 times reduction in outage probability for cell-edge users at 12.5 dB SINR, thereby demonstrating strong suitability for B5G deployment requirements.The proposed CNOMA-based hybrid relaying scheme outperforms conventional resource allocation approaches, offering a reliable and efficient communication framework for B5G networks, particularly benefiting UEs near the cell edge.These findings underline the potential of CNOMA-based adaptive and opportunistic resource allocation in addressing the evolving demands of next-generation wireless networks.

Cet article est une proposition de travail et de pensée autour des vécus de fin du monde et d’effondrement que l’on ressent parfois au sein des institutions. C’est un essai d’élaboration de la pensée soignante en pédopsychiatrie à l’heure des protocoles hospitaliers et du management néo-libéral qui déshumanisent. À travers le retour à une certaine praxis et la théorie de la psychothérapie institutionnelle, nous témoignons et construisons du sens, une éthique et une qualité d’être avec l’autre, qui permet de faire advenir un désir qui soigne.

The immunopathogenesis of dengue virus (DENV) infection remains incompletely understood. To increase our understanding of inflammatory response in non-severe dengue, we assessed longitudinal changes in the inflammatory proteome in patients with an acute DENV infection. Using a multiplex proximity extension assay (PEA), we measured relative levels of 368 inflammatory markers in plasma samples from hospitalized patients with non-severe DENV infection in the acute (n = 43) and convalescence (n = 35) phase of the infection and samples of healthy controls (n = 10). We identified 203 upregulated and 39 downregulated proteins in acute versus convalescent plasma samples. The upregulated proteins had a strong representation of interferon (IFN) and IFN-inducible effector proteins, cytokines (e.g. IL-10, IL-33) and cytokine receptors, chemokines, pro-apoptotic proteins (e.g. granzymes) and endothelial markers. A number of differentially expressed proteins (DEPs) have not been reported in previous studies. Functional network analysis highlighted a central role for IFNγ, IL-10, IL-33 and chemokines. We identified different novel associations between inflammatory proteins and circulating concentrations of the endothelial glycocalyx disruption surrogate marker syndecan-1. Conclusion: This unbiased proteome analysis provides a comprehensive insight in the inflammatory response in DENV infection and its association with glycocalyx disruption.

Many academic libraries have implemented personal librarian programs, seeking to improve relationships with students and reduce library anxiety. This pilot study, in which a personal librarian was assigned to sections of a general education course, aimed to expand upon the personal librarianship literature by assessing whether a personal librarian influences student academic outcomes and information literacy confidence. Results from the pilot suggest that the presence of and engagement with the personal librarian had minimal and not statistically significant effect on academic outcomes, but engagement with the personal librarian somewhat correlated with growth in information literacy confidence.

BackgroundEndothelial hyper-permeability with plasma leakage and thrombocytopenia are predominant features of severe dengue virus infection. It is well established that heparanase, the endothelial glycocalyx degrading enzyme, plays a major role in various diseases with vascular leakage. It is yet to be elucidated whether heparanase activity plays a major role in dengue-associated plasma leakage. Moreover, the major source of heparanase secretion and activation in dengue remains elusive. Since a relatively high amount of heparanase is stored in platelets, we postulate that heparanase released by activated platelets contributes to the increased plasma heparanase activity during dengue virus infection.MethodsHeparanase activity (plasma and urine), and heparan sulfate and syndecan-1 (plasma levels) were measured in dengue patients with thrombocytopenia in acute phase (n=30), during course of disease (n=10) and in convalescent phase (n=25). Associations with clinical parameters and plasma leakage markers were explored. Platelets from healthy donors were stimulated with dengue non-structural protein-1, DENV2 virus and thrombin to evaluate heparanase release and activity ex vivo.ResultsHeparanase activity was elevated in acute dengue and normalized during convalescence. Similarly, glycocalyx components, such as heparan sulfate and syndecan-1, were increased in acute dengue and restored during convalescence. Increased heparanase activity correlated with the endothelial dysfunction markers heparan sulfate and syndecan-1, as well as clinical markers of plasma leakage such as ascites, hematocrit concentration and gall-bladder wall thickening. Notably, platelet number inversely correlated with heparanase activity. Ex vivo incubation of platelets with thrombin and live DENV2 virus, but not dengue virus-2-derived non-structural protein 1 induced heparanase release from platelets.ConclusionTaken together, our findings suggest that the increase of heparanase activity in dengue patients is associated with endothelial glycocalyx degradation and plasma leakage. Furthermore, thrombin or DENV2 activated platelets may be considered as a potential source of heparanase.

Cervical disc bulge or other cervical spine diseases often results into neck and arm pain in patients formulating an etiology of direct impingement of nerve roots and associated inflammatory process.The clinical presentation also corresponds with the ipsilateral symptoms associated with the cervical disorder as depicted in the patient.A 33 year's old South Indian male is diagnosed with Para-central bulge at the level of C4/5 and C5/C6-Intervertebral disc presented to the physical therapy with neck pain radiating into left sided upper and lower extremity pain.A magnetic resonance imaging revealed mild Para central bulge of C4/5 and C5/6-Intervertebral disc with mild narrowing of the left intervertebral foramen.Results from MRI scan show the alignment and the morphology of the vertebrae to be normal.Also, the CSF displays normal intensity in all sequences.The patient reported to physical therapy for cervical pain and Radiculopathy.After evaluation he was asked to continue with regular home exercise programme like cervical lateral flexion stretch, unilateral wall stretch which resulted to reduce the cervical pain and shows improvement in its subsequent symptoms.

Aim: To analyse the increasing burden of coronary artery disease (CAD) in tropical and subtropical belts of the Equator since it remains blurred and carries a grim prognosis. Introduction: Endomyocardial fibrosis [EMF] is a tropical febrile disorder, confined to peculiar and limited geographical areas. Plaque buildup in endocardium and coronary arteries, causing ischemic injury and arrhythmic episodes, is a vanishing mystery in its pathogenesis and emphasizing alternative routes for understanding and treatment of this enigmatic disease. Case Report: 15 cases in various age groups were reported with potential complications of coronary artery disease and arrhythmias, associated with endocardial lesions, the characteristic feature of endomyocardial fibrosis. Conclusion: The narrowing of coronary arteries as a result of thickening of the walls, spasm, inflammation, plaques and its rupture produce ischemic episodes which can occur slowly or suddenly in a devastating pattern with arrhythmogenic potentials. The important steps to prevent and decrease the risk of CAD is to reduce the chance of getting this disorder by epidemiological measures with an advice of blood thinning medications such as small daily dose aspirin, antibiotics in susceptible individuals and revascularization in established myocardial infarction.

Abstract Objectives: Drivers with certain mental illnesses are obliged by the Driver & Vehicle Licensing Authority (DVLA) to stop driving and to report their condition. This study aims to quantify the number of psychiatric patients failing to meet the DVLA standards of ‘fitness to drive’ and to record how frequently psychiatrists failed to advise patients of these standards.Method: In this prospective descriptive study, 10 psychiatrists reported by questionnaire the diagnosis and driving status of all patients encountered over a four week period. They recorded their advice given to patients failing to meet the DVLA criteria of ‘fitness to drive’ and advice given when prescribing psychotropic medication.Results: Of 297 patients, 123 (41%) were drivers. 19/123 (13%) of drivers failed to meet the DVLA standards of ‘fitness to drive’. In 9/19 of these cases the psychiatrist did not advise the patient in line with the DVLA guidelines. This was especially the case for alcohol related disorders. Of drivers 49% were prescribed psychotropic medication with potential adverse effects on driving.Conclusions: Driving amongst mentally ill patients appears commonplace. In this study, 13% of drivers were considered by the authorities to be unfit to drive. Psychiatrists frequently used their own judgement when advising patients regarding driving. This arguably contravenes doctors' responsibilities to patients and has potential legal implications for both the patient and psychiatrist.
