Item O uso de relógios inteligentes na aferição de frequência cardíaca de pacientes internados com diagnóstico de hipertensão arterial sistêmica com Covid-19(Universidade Brasil, 2021) Vieira, Leonardo Matos; Carvalho, Jancineide de Oliveira de; Marciano, Fernanda RobertaWearable technologies become an important topic in the field of health technology for the monitoring and storage of health-related data. Pulse oximetry is the most used wearable in the continuous monitoring of vital signs. However, smart watches have been occupying a space in the portion of the population that practice physical activities with the aim of monitoring heart rate (HR) during their practice. Thus, this study infers about the use of smart watches as an instrument for measuring HR in hospitalized patients diagnosed with systemic arterial hypertension affected by covid-19. For this purpose, HR collection was carried out in 30 patients aged between 40 and 80 years old from male and female internships at Hospital de Campanha in Bacabal/MA, using a digital watch (Fitbit, charge HR) and a finger oximeter as a reference value. The devices (watch and oximeter) were placed on the left arm wrist and on the left index finger simultaneously during 30 minutes of evaluation in the patients. In addition to the HR collected by the devices, other vital signs were observed, such as blood pressure (sphygmomanometer), oxygen saturation (finger oximeter) and respiratory rate by analyzing the electrodes placed on the patients. ANOVA analyzes of variance were performed followed by Tukey's Comparison post-test and Pearson's correlation test with the aid of the GraphPadPrism version 7.0 software (GraphPad Software, San Diego, CA, USA). The results indicated that they were patients with a mean age for the male gender of 65.00 ± 15.39 years and for the female gender of 65.91 ± 23.06 years, with a respiratory rate per minute of 20.47 ± 0.5679 and 20.6 ± 0.3754 for males and females respectively, in addition to a similarity of 83.3% in HR measurements performed with the watch (84.9 ± 4.29 bpm) in relation to those with the oximeter (88.2 ± 3.75 bpm) with a Pearson correlation for r = 0.71. It can be concluded that the smart watch can be another instrument to be taken into account during the evaluation of vital signs with the same efficiency as that verified by the oximeter.Item Influência da Terapia por Fotobiomodulação no tratamento de condições inflamatórias pulmonares e seu impacto sobre o Covid-19(Universidade Brasil, 2021) Macedo, Daniela Bezerra; Tim, Carla Roberta; Garcia, Lívia AssisToday we are facing a pandemic that continually causes high rates of deaths and catastrophic and countless economic and psychosocial consequences. Thus, this period requires a rapid search for viable procedures that can allow us to use safe and noninvasive clinical tools as prophylactic or even adjuvant methods in the treatment of COVID-19, thus constituting an important challenge to the medical clinic. Evidence shows that photobiomodulation therapy (PBMT) is shown to attenuate the inflammatory process and reduce respiratory disorders similar to acute lung injury (ALI), complications associated with infections, such as that caused by the new Coronavirus (SARS-CoV-2). Thus, the aim of this study was to evaluate the influence of laser PBMT on infrared length in the treatment of ALI, one of the main critical complications of COVID-19 infection, in an experimental model of rats. Twenty-four male Wistar rats were randomly allocated into three experimental groups (n = 8): Control (CG); LPA (LPA); LASER-treated LPA (LPAL). For the treatment, a laser equipment (808 nm; 30 mw; 1.8 J) was applied at three points (anterior region of the trachea and in the venereal regions of the thorax bilaterally) in the period of 1 and 24 hours after lpa induction. Descriptive histopathological analysis, lung injury score, analysis of the number of inflammatory cells, interleukin 1 β (IL-1β) and interleukin 10 levels (IL-10) were performed for treatment evaluation. In the results, it was possible to observe that the treatment reduced inflammatory infiltrates, there was thickening of the alveolar septum and the pulmonary injury score when compared to the LPA group. In addition, laser PBMT showed lower immunoexpression of IL-1β, however, it did not alter the levels of pulmonary IL-10. Thus, it can be concluded with this experimental study that infrared laser PBMT was efficient in attenuating ALI, one of the main complications of COVID-19, since it was able to reduce the inflammatory process, as well as increase the production of anti-inflammatory cytokines.
