The circle-ring resistance exercise according to vibration frequency was conducted in a vibration exercise apparatus 3 times a week for 30 minutes for a total of 8 weeks. The study used an ultrasonic instrument to measure trunk muscle thickness before as well as 4 and 8 weeks after the experiment. The results indicated that the external oblique and the internal oblique had significant differences in time-to-time and time-group interaction (p0.05). Transversus abdominis showed significant differences in time-to-time and time-and-group interaction as well as inter-group interaction (p Keywords: Vibration; Circle-Ring Exercises; Trunk Muscle Thickness

Calle 127 # 20 – 56 6th floor, Colombia DOI: 10.26717/BJSTR.2020.30.004910 Introduction: The pandemic caused by the novel coronavirus SARS-CoV-2 has increased the demand for health services and thereby created a shortage of personal protective equipment for health workers. In a real scenario of a shortage of N95 filtering facepiece respirators, organizations such as the Centers for Disease Control and Prevention recommend the alternative use of reusable elastomeric respirators. Objective: To perform a hospital-based health technology assessment of reusable half-face and full-face elastomeric respirators for use in intensive care units focused on patients with a confirmed or suspected diagnosis of COVID-19. Method: The process was carried out with a multicriterion decision approach to assess six domains according to the recommendations of the European Network for Health Technology Assessment. Results: The available evidence on reusable elastomeric respirators in healthcare settings is scarce. The studies found allow us to recommend the use of elastomeric respirators in a conditional context of a shortage of N95 respirators in specific areas, and our analysis shows that they are less expensive. These respirators are the first-line alternative to scarce N95 respirators and have cost advantages in the simulation scenario. A training, monitoring, and assessment strategy must be in place for the implementation of reusable elastomeric respirators. At the organizational level, the use of these respirators is perceived as safe and comfortable. Conclusions: This hospital-based health technology assessment shows that reusable elastomeric respirators can be used in intensive care units as a rational alternative to disposable N95 respirators whose shortage is caused by a pandemic.

The purpose of this study was to investigate the difference between the kinds of biomaterials the osseointegration enhanced by LIPUS in vitro. Hydroxyapatite (99.9%) and Bio-active titanium were soaked in simulated body fluid under the LIPUS radiation, and accessed by scanning electron microscope and X-ray diffraction, the mass of precipitation was measured.In a result, bio-active titanium showed the more rich bone-like apatite formation on the surface than hydroxyapatite. These facts suggested that the formation of bone-like apatite might depend on the initial epitaxial nucleation growth on the biomaterial surface.

The current therapeutic approaches are alike discussed. The basically unchanged mortality rate of this condition reflects the basically unchanged therapy guidelines. Of the three really innovative treatments that have been proposed during the last forty years (naloxone; vagus stimulation; melanocortins), the first two have been abandoned after an initial, rather entusiasthic endorsement, and the third has been neglected: the reasons are discussed.

COVID-19 has a high inflammatory burden which places patients at risk for developing repolarization changes with resultant prolongation of the QT syndrome and Torsades de Pointes (TdP). This is potentially further exacerbated by medications being used to treat COVID-19. However, there have been no cases of TdP reported without a specific link to medication during a COVID-19 infection.

System of acupuncture channels (АС) reflects the basic processes in the body, rhythm and symmetry are also peculiar to them, which through them can be estimated much more simply than, for example, based on biochemical or physiological parameters of the body. Methods: A patient with type 1 diabetes performed 43 Akabane tests at different times of the day for 18 days. With each test, she recorded blood sugar, insulin dose and assessed the effect on the body of various other factors in arbitrary units (from 1 to 10) with an assessment of their effect on the level of glycemia using regression and correlation analysis. The rhythmic activity of АС was also analyzed using Cosinor analysis. Results: It was found that the influence on the level of glycemia through certain AС is exerted by many external and internal factors. In routine monitoring of blood sugar, they cannot be foreseen, because blood glucose itself is the final product in a large chain of metabolic reactions that cannot be controlled in this way. The activity of certain AС reflects these influences and changes cyclically, which can be used to evaluate biorhythms. It was shown that a correctly selected medicine at an individual level restores symmetry in the body, which is broken at different levels from the effects of the disease. Conclusion: Using the regression analysis and the Cosinor method for assessing the contribution of AС to glycemia, it is shown that different AС have different phases, amplitudes and periods of biorhythms, therefore, due to their interference within the same regression model, sharp fluctuations glycemia are possible, which can be predicted in time. By assessing the asymmetry at the AС level in the body, it is also possible to carry out individual selection of drugs and their doses Keywords: Akabane Test; Medicine Action; Chronopharmacology; Kosinor - Analyses; Telemedicine
