Heart Beat Monitoring And Wireless Data Logging Using Arm Cortex A8

Increasing importance in monitoring and logging the real time patient’s related data has led to the development of a new wireless data acquisition system. The basic concept presented in this paper is that we have made one type of wireless data logger[1] system using arm platform which is logging the real time heartbeat[2] data in one text file it is give the heartbeat rate with respect to time. Here we use UDOO[8] development board, UDOO is a single-board computer development platform that merges a dual or quad core ARM Free scale Cortex-A9 i.MX.6 CPU and an Arduino[4] compatible board embedded with a dedicated ARM Atmel SAM3X8E CPU. Physical data is converted in to the electrical form using Arduino UNO R3 and after processing these data it will be transmitted by the RFM. Same way at receiver side one RFM device is required to receive the data which was transmitted by the transmitter. Once the data is received, these data will be given to UDOO board. In UDOO board the data is processed and the data will be monitored on LCD or DVI Monitor

Emerging trends in healthcare driven by the COVID-19 pandemic: A review from Health Informatics Perspective.

The COVID-19 pandemic is the first of its kind to hit the world in the modern information age. People working in healthcare across the globe have harnessed technological advances and modern digital tools in innovative new ways. This has brought specific, more recent trends in healthcare delivery to the forefront. In this review, we present a collection of articles that highlight some of the emerging trends in healthcare driven by the COVID-19 pandemic and that have the potential to transform healthcare in the coming decades. We provide a brief commentary on the opportunities and challenges for each trend

The purpose of this study was to compare plasma differences in inflammatory cytokines including tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6), in addition to the stress hormone cortisol, during prolonged cycling under normal and hot environmental conditions in elite cyclists.Methods and design: Six trained elite male cyclists (27 ± 8 years; 75.5 ± 4 kg; maximum oxygen uptake [VO2max] = 66 ± 6 mL/kg/min, mean ± SD). The cyclists biked for 2.5 h at their prescribed 60% maximum exercise workload (Wmax) or 75% VO2max either in an environmental chamber set at 15°C and 40% relative humidity (NEUTRAL) or at 35°C and 40% relative humidity (HOT). The cyclists were given 4 mL of water/kg body weight every 15 min under both conditions.Results: Total cortisol concentrations were elevated (P < 0.05) immediately postexercise and 12 h postexercise in both the NEUTRAL and HOT conditions. TNF-α concentrations were only significantly (P = 0.045) elevated postexercise in HOT conditions. During the HOT conditions, a significant (P = 0.006 and 0.007, respectively) difference in IL-6 was seen immediately after and 12 h postexercise. During the NEUTRAL condition, IL-6 was only significantly elevated postexercise (P < 0.05).Conclusions: Heat exposure during a long bout of exercise is sufficient to elicit stress response in elite cyclists. However, the degree of release of anti-inflammatory and proinflammatory cytokines might be related to several factors that include the athlete’s fitness level, hydration status, exercise intensity, and length of exposure to hot environments.Keywords: cytokines, inflammation, heat, exercise, performance&nbsp

Application of an industrial waste magnetic iron dust as a solid phase support for immobilizing enzyme of industrial applications

Magnetic iron dust, a byproduct by many chemical industries that performs the reduction of nitro compounds to amine, was used for laccase immobilization. The characterization of magnetic iron dust was done by X-ray diffraction, Fourier-transform infrared, and dynamic light scattering. Biodegradable polymer, chitosan, was coated on to the magnetic iron dust by reverse phase suspension method, which was confirmed by Fourier-transform infrared analysis. Immobilization of the laccase enzyme was done onto the chitosan-coated and non-coated magnetic iron dust. The immobilization was monitored by Fourier-transform infrared analysis. Binding efficiency, optimum pH, and optimum temperature for these immobilized laccases were investigated. X-ray diffraction pattern of magnetic iron dust confirmed presence of magnetite (Fe 3 O 4 ) and maghemite (γ-Fe 2 O 3 ) with a particle size of 529.6 nm measured by dynamic light scattering. Laccase was immobilized on chitosan-coated and non-coated magnetic iron dust, monitored by Fourier-transform infrared spectra. Binding efficiency of the laccases was found to be 100% onto the coated and non-coated magnetic iron dust and their activity remained to be 63% and 82%, respectively, even after the 10th cycle of their use. The present results demonstrated the applicability of these immobilized laccase system in the industry in terms of their reusability and waste recycling

Diagnostic, Surgical, and Technical Considerations for Lumbar Interbody Fusion in Patients with Osteopenia and Osteoporosis: A Systematic Review

Objective: Osteoporosis is increasing in incidence as the ageing population continues to grow. Decreased bone mineral density poses a challenge for the spine surgeon. In patients requiring lumbar interbody fusion, differences in diagnostics and surgical approaches may be warranted. In this systematic review, the authors examine studies performing lumbar interbody fusion in patients with osteopenia or osteoporosis and suggest avenues for future study. Methods: A systematic literature review of the PubMed and MEDLINE databases was performed for studies published between 1986 and 2020. Studies evaluating diagnostics, surgical approaches, and other technical considerations were included. Results: A total of 13 articles were ultimately selected for qualitative analysis. This includes studies demonstrating the utility of Hounsfield units in diagnosis, a survey of surgical approaches, as well as exploring the use of vertebral augmentation and cortical bone screw trajectory. Conclusions: This systematic review provides a summary of preliminary findings with respect to the use of Hounsfield units as a diagnostic tool, the benefit or lack thereof with respect to minimally invasive approaches, and the question of whether or not cement augmentation or cortical bone trajectory confers benefit in osteoporotic patients undergoing lumbar interbody fusion. While the findings of these studies are promising, the current state of the literature is limited in scope and, for this reason, definitive conclusions cannot be drawn from these data. The authors highlight gaps in the literature and the need for further exploration and study of lumbar interbody fusion in the osteoporotic spine
