    Abstract Ischemic heart condition is one of the most prevalent causes of death that can be treated more effectively and lead to fewer fatalities if identified early. Heart muscle fibrosis affects the diastolic and systolic function of the heart and is linked to unfavorable cardiovascular outcomes. Cardiac magnetic resonance (CMR) scarring, a risk factor for ischemic heart disease, may be accurately identified by magnetic resonance imaging (MRI) to recognize fibrosis. In the past few decades, numerous methods based on MRI have been employed to identify and categorize cardiac fibrosis. Because they increase the therapeutic advantages and the likelihood that patients will survive, developing these approaches is essential and has significant medical benefits. A brand-new method that uses MRI has been suggested to help with diagnosing. Advances in deep learning (DL) networks contribute to the early and accurate diagnosis of heart muscle fibrosis. This study introduces a new deep network known as FibrosisNet, which detects and classifies fibrosis if it is present. It includes some of 17 various series layers to achieve the fibrosis detection target. The introduced classification system is trained and evaluated for the best performance results. In addition, deep transfer-learning models are applied to the different famous convolution neural networks to find fibrosis detection architectures. The FibrosisNet architecture achieves an accuracy of 96.05%, a sensitivity of 97.56%, and an F1-Score of 96.54%. The experimental results show that FibrosisNet has numerous benefits and produces higher results than current state-of-the-art methods and other advanced CNN approaches.

    Abstract Warfarin-induced skin necrosis is a rare complication of anticoagulant treatment. The incidence of this complication is undetermined, but it has been estimated to occur between 1:100 and 1:10,000 of patients treated with anticoagulants. Coumarin skin necrosis occurs almost exclusively in patients with venous thrombosis between the 3rd and 10th day after beginning anticoagulation. Although protein C deficiency is the most common underlying hypercoagulable state reportedly associated with warfarin skin necrosis, very few cases have been linked to congenital protein S deficiency. This article addresses the association of hereditary protein S deficiency and warfarin skin necrosis, and provides suggestions for management.

    Abstract Posterior reversible encephalopathy syndrome (PRES) refers to a disorder of reversible vasogenic edema caused by rapid hyperperfusion of the brain that classically involves areas supplied by the posterior circulation such as the parieto-occipital region. It may present with atypical features such as brainstem and spinal cord involvement. Common causes include renal failure, pre-eclampsia/eclampsia among pregnant women, rapid changes in systemic blood pressure, and autoimmune diseases. The most prevalent presenting signs and symptoms are encephalopathy, seizures and headache. A 64-year-old female presented to a dialysis unit after missing several sessions with twitching in her extremities and elevated blood pressure. Additionally, she recently terminated clonidine use and was likely experiencing rebound hypertension. The continuous electroencephalogram (EEG) demonstrated generalized, non-convulsive seizures. MRI findings were notable for hyperintensities in the pons, middle cerebellar peduncles, cerebellar hemispheres, and periventricular and subcortical matter with medulla and proximal spinal cord involvement. A notable clinical sequela of PRES in this patient was coma. Aggressive blood pressure control led to significant improvement and return to her neurologic baseline. PRES can present with extensive brainstem involvement with a clinical sequela of coma. Multiple underlying causes such as dialysis non-adherence and rebound hypertension following clonidine discontinuation contributed to the development of this condition in this patient.

    Abstract Refined hybrid convolutional neural networks are proposed in this work for classifying brain tumor classes based on MRI scans. A dataset of 2880 T1-weighted contrast-enhanced MRI brain scans are used. The dataset contains three main classes of brain tumors: gliomas, meningiomas, and pituitary tumors, as well as a class of no tumors. Firstly, two pre-trained, fine-tuned convolutional neural networks, GoogleNet and AlexNet, were used for classification process, with validation and classification accuracy being 91.5% and 90.21%, respectively. Then, to improving the performance of the fine-tuning AlexNet, two hybrid networks (AlexNet-SVM and AlexNet-KNN) were applied. These hybrid networks achieved 96.9% and 98.6% validation and accuracy, respectively. Thus, the hybrid network AlexNet-KNN was shown to be able to apply the classification process of the present data with high accuracy. After exporting these networks, a selected dataset was employed for testing process, yielding accuracies of 88%, 85%, 95%, and 97% for the fine-tuned GoogleNet, the fine-tuned AlexNet, AlexNet-SVM, and AlexNet-KNN, respectively. The proposed system would help for automatic detection and classification of the brain tumor from the MRI scans and safe the time for the clinical diagnosis.

    Abstract Utilising elements of Coordination and Context-Appropriate Power Theory (CCAP) as a framework, this article assesses the efforts of the General Transport, Petroleum and Chemical Workers’ Union (GTPCWU) in Ghana to defend the rights of workers in the oil industry. Whether the GTPCWU has been able to effectively employ structural, institutional and conditional forms of power is examined within the CCAP framework. The analysis is informed by first-hand knowledge of trade union policies and practices, as one of the authors is a GTPCWU official. The research also draws on interviews and email communications with other Ghanaian trade unionists and an academic specialising in labour issues. The findings indicate that the structured labour regime, in which the GTPCWU is embedded, makes it hard for the union to employ structural, institutional and conditional forms of power fruitfully. Nevertheless, agency on the part of union officials and members is significant. This is evidenced by the success of individual union actions, indicating that the GTPCWU possesses a degree of structural power. Utilising institutional power effectively is difficult for the union, as enforcement of labour legislation is weak, and lengthy legal processes ensue when cases do reach court. It is also burdensome for the GTPCWU to exercise conditional power, based on obtaining support from non-union individuals and groups, since its members are widely perceived to have well-paid employment in the formal sector. The GTPCWU’s need for assistance in supporting its members through the transition away from fossil-based systems of energy production is outlined. Capacity-building initiatives, including the construction of a training and conference facility, and recruitment campaigns, focusing on attracting more women and youth members, are discussed.

    Abstract Plasmablastic myeloma is a rare variant of multiple myeloma characterised by neoplastic proliferation of single clone of plasma cells producing monoclonal immunoglobulins. A 60-year-old man presented to hospital with a 6-week history of chest pain, back pain, leg weakness and numbness. Imaging revealed a 75 mm left lobular lung mass with chest wall invasion, metastatic bony and soft-tissue deposits and spinal cord compression at T5 level. Lung biopsy, for suspected metastatic lung cancer, surprisingly showed features of plasmablastic myeloma. Protein electrophoresis demonstrated 2 g/L of IgG lambda paraproteinaemia and an increase in lambda light chains with reduced kappa/lambda ratio of 0.01. Bone marrow biopsy did not show evidence of infiltration by disease. The patient received radiotherapy to the spine; responded to third-line chemotherapy and received autologous stem cell transplant. This case adds to the rare causes of lung mass and is the first reported case of plasmablastic myeloma diagnosed on lung biopsy.

    Abstract Respiratory viral infections remain a major cause of hospitalization and death worldwide. Patients with respiratory infections often lose weight. While acute weight loss is speculated to be a tolerance mechanism to limit pathogen growth, severe weight loss following infection can cause quality of life deterioration. Despite the clinical relevance of respiratory infection-induced weight loss, its mechanism is not yet completely understood. We utilized a model of CD 8

    Abstract The study utilized instrumental neutron activation analysis (INAA) and X-ray fluorescence (XRF) to accurately analyze the elemental composition of 28 felsite (rhyolite), rock samples. Statistical approaches, including bivariate and multivariate analysis, were employed to characterize the rocks and determine their origin. Major findings include significantly high levels of silicon (297000 ± 4000) mg/kg and low levels were noticed for gold (0.10 ± 0.01) mg/kg. The dominant major elements in the rocks were ranked as follows: silicon > aluminum > potassium > sodium > zirconium > calcium > zinc > manganese. A comparison with the upper continental crust (UCC) revealed higher levels for most elements, except for a few. The study also identified substantial amounts of uranium and thorium. Variations in elemental composition were observed both between different profiles and within felsite (rhyolite) rock samples, indicating heterogeneity and varying origins of the rocks. The findings contribute valuable baseline data for the area and highlight its economic significance for Egypt. Additionally, the study addresses the integration of results from different analytical methods, providing a comprehensive answer to this issue.

    Abstract The James A. Haley Veterans' Hospital in Tampa, Florida has developed an innovative approach to the unique rehabilitation needs of active duty Special Operations Forces (SOF) and veterans with chronic conditions related to their military service. Tampa's program, the Post-Deployment Rehabilitation and Evaluation Program (PREP), was established in 2008. The interdisciplinary team includes one nurse practitioner and eight staff registered nurses. The Veterans Health Administration (VHA) is using Tampa's established and successful PREP as a model to actively expand the program to other Veterans Administration (VA) Polytrauma Rehabilitation Centers over the next several years. There are several important nursing and rehabilitation team considerations for the successful development of these mild traumatic brain injury (mTBI) inpatient rehabilitation programs.
