Item Efeitos da fotobiomodulação e cinesioterapia no tratamento da osteoartrite de joelho: estudo clínico, prospectivo e randomizado(Universidade Brasil, 2020) Lima, Geovane Elias Guidini; Baptista, AlessandraOsteoarthritis is a chronic joint disease characterized by gradual destruction of cartilage, which can generate pain, muscle weakness, deficit in the range of motion, stiffness and impairment in function. The aim of this study was to compare the effects of kinesiotherapy associated or not with photobiomodulation on the intensity of pain, range of motion, physical function and muscle strength of the quadriceps femoris and hamstrings in patients diagnosed with knee osteoarthritis (KOA). 28 patients participated in this study, randomly divided into 2 treatment groups, performed 3 times a week, for 6 weeks: Kinesiotherapy Group (KG), submitted to stretching, self mobilization, muscle strengthening and sensorimotor training and Kinesiotherapy and Photobiomodulation Group (KPG), submitted to the same program as the KG followed by infrared laser irradiation (808 nm, 100mW - 5 points in the medial joint region of Joelho and 4 points lateral, 3J / point; 30 s per point). Blinded evaluators assessed pain at rest and movement and range of motion using the visual analog scale (VAS) and goniometry, respectively. To assess physical function, the WOMAC questionnaire (Western Ontario and MacMaster University Osteoarthritis Index) and functional tests were used: Sit and stand test; 2 min walk test. The muscular strength of the quadriceps and hamstrings were measured using an isometric dynamometer. The evaluations were performed in 4 moments: before (EV0), during (EV1: 3 weeks of treatment), at the end (EV2: after 6 weeks of treatment) and 30 days after the end of treatment (follow-up). When comparing treatments, the combination of treatments showed a reduction in joint pain intensity at rest, an increase in knee flexion amplitude, an improvement in physical function and an increase in muscle strength of quadriceps femoris when compared to KG (p <0.05). In the intra-group analysis, our results showed a significant improvement in all variables studied (p <0.05), and in some variables only after 3 weeks of intervention. we can conclude that a kinesiotherapy associated with photobiomodulation can be a good adjunctive treatment in OAJ.Item Efeito clínico da fotobiomodulação transcraniana em paratletas com paralisia cerebral(Universidade Brasil, 2020) Garcez, Edna de Morais; Baptista, AlessandraTranscranial photobiomodulation (t-PBM) is a non-invasive therapy modality that promotes increased of cerebral energy metabolism and antioxidant defenses. This therapy uses light, usually from a laser or LED to stimulate mitochondrial metabolism, promoting a higher energy supply in the cells. The aim of this study was to evaluate the effects of t-PBM on motor and intralimbal coordination of brain-damaged parathletes. Six parathletes were evaluated, classified according to the parameters defined by the International Paralympic Committee, in BC1, BC2 and BC3, aged between 23 and 41 years. Each parathlete was submitted to t-PBM of the whole head through a helmet composed of 204 LEDS, with interspersed wavelengths of 660 and 850 nm (CAPELLUX I9, Comedical, Mauá / SP, Brazil), 3 times per week on alternate days, for 15 min, for 2 weeks. To assess the effects of t-PBM, manual dexterity and intralimbal coordination tests (ILC) were performed before the start of treatment, 7 days and 14 days after. The results showed how the continuous movements for the evaluation of manual dexterity and tested ILC, seem to have the capacity to distinguish the motor limitations of the players, confirming the classification of the International Paralympic Committee. The evaluation of the manual dexterity showed a significant gradual improvement in the manual dexterity, after t-PBM sessions, for both the dominant and non-dominant hands (p<0.05). The evaluation tests of the ILC showed that there was no reduction in the time to perform horizontal movements in both the dominant and non-dominant hands, after 3 and 6 sessions of t-PBM (p>0.05). However, the evaluations of the vertical movements showed that there was a reduction in the execution time of the exercise in the dominant hand, between the initial and the final evaluation and in the non-dominant hand, the reduction in time occurred only between the second and the third evaluation (p <0.05). Finally, the continuous vertical touch test showed a gradual and significant increase in the number of vertical movements in the two groups tested, when compared to the initial and final values (p<0.05). Therefore, we can conclude that t-PBM presents itself as an effective alternative in the improvement of motor coordination, assessed through tests of manual dexterity and intralimbal coordination, in practicing athletes of adapted bocce.Item Efeitos da fotobiomodulação no desempenho esportivo de paratletas de natação - uma série de casos(Universidade Brasil, 2020) Garcez, Aguinaldo Silva; Baptista, AlessandraPhotobiomodulation (PBM) uses light, usually from a laser or LED, to stimulate, heal and / or regenerate damaged tissues. Recently, it has been used to increase sports performance in athletes. The aim of this study was to demonstrate the effects of PBM on cardiorespiratory function and swimming performance in parathletes. Ten young adult parathletes, men and women, swimmers of the AACD team, São Paulo - Brazil, were tested before and after the PBM applied to the upper musculature. They are diagnosed with cerebral palsy, myelomeningocele and congenital malformation. Before the test, they performed a 10 min swim warm-up in a 50 m pool. They rested for 1 min and their heart rate was recorded. Parathletes performed 3 swimming sessions, in freestyle, with maximum effort, with an interval of 5 min between each series and the average performance time was recorded. After a recovery period of one week, the upper muscles: biceps, deltoid and trapezius were irradiated, bilaterally, for 10 min, with a set of LEDs, each area receiving 108 J. After every 50 m of swimming, performance time, peak heart rate and recovery after 1 min were recorded. Comparisons were made before, after irradiation with PBM and after placebo, in a crossover design. All the parathletes improved the time in the 50 m swim. On average, the time decreased about 4 s after PBM and about 1.5 s after placebo. The peak heart rate was 10% lower after irradiation, when compared to non irradiated placebo. The recovery heart rate was also better for all athletes. The results suggest that a muscle preconditioning regime, using PBM with low-power infrared laser, before intense exercise can modulate the function of the upper musculature and the recovery of heart rate, leading to a better swimming performance in young adult parathletes.Item Aplicativo móvel multiplataformas para gestão de cuidados para idosos(Universidade Brasil, 2021) Chagas, Renata Kelen; Nunez, Silvia CristinaThe aging of the world population has been taking place in recent decades as result of the decrease in birth rates and better health care that allows for an increase in life expectancy. Senile dementias are examples of diseases that can affect the elderly, reducing independence and self-care. With the presence of women in the labor market and the reduced number of children, the elderly must often live under the care of others who have professional experience to provide appropriate medical care, but lack of contact with the family and unfamiliarity with habits and tastes can reduce the quality of life of the elderly. Technological advances must be used to reduce the distance between families, caregivers, doctors and the elderly. The objective of this work is to develop an application for mobile devices that facilitates communication between health service providers for the elderly residing in long-stay institutions. The CuidaLife application was developed for a software operating system with input modules for registering elderly people, family members, doctors and caregivers. The developed application can be accessed through any smartphone, tablet or computer, as long as it has internet access. Its layout is responsive, that is, it adjusts according to the screen size of the equipment. The elderly registration modules were designed to allow the exchange of information about the elderly not only medical, but also including food preferences, habits that are important for daily well-being and exchange of personal photos between family and elderly. The caregivers module allows the exchange of information between caregivers' shifts, with information relevant to the care of the elderly, and the medical module allows access to health information relevant to the monitoring of the elderly. The application worked well and can represent an easy and safe way to improve the quality of life of individuals who depend on third parties for their care.Item Análise do Desempenho Laboral de Deficientes Intelectuais Inseridos em uma Rede Varejista nos Municípios de Itabuna e Ilhéus: pesquisa de campo, com abordagem investigativa de caráter qualitativo e quantitativo(Universidade Brasil, 2020) Matos, Rebeca Rodrigues Faislon; Baptista, AlessandraCompanies seek, within a technical and human complexity, to build work processes that meet the expectations of customers who request specific quality services and adapted to their needs. The objective of this work was to evaluate the productivity and adaptability of employees with intellectual disabilities (ID) inserted in the labor market in a retail chain in the municipalities of Itabuna and Ilhéus. Twenty individuals with ID and 20 individuals without such impairment were evaluated, inserted in the organizational context as a packager. The assessments were made by managers and co-workers without intellectual commitment, in order to assess how the interpersonal relationships of these employees with ID and their contribution to the company are established, and finally an interview was conducted with employees with ID to assess the profile of these employees and the degree of satisfaction in being inserted in the labor market. The results of the managers' assessment showed statistically significant differences (p<0.05) in relation to behavioral characteristics, interpersonal relationships and productivity between employees with and without ID. With regard to attendance and customer service, the managers' assessment did not show statistically significant differences between those assessed (p>0.05). The questionnaire among the peers showed that employees with ID perform well at work, in interpersonal relationships with other employees and with customers, and that the hiring of these individuals is highly regarded by society and by co-workers. And finally, the interviews with employees with ID showed that 95% of those hired with ID, by the evaluated institutions, are male and the results showed positive unanimity of employees with ID in relation to their role and the help of other employees. Therefore, we can conclude that the evaluations performed showed the relevance of the work in terms of reducing the social stigma of the employee with ID, as well as expanding the possibility of hiring these individuals.Item Desenvolvimento e avaliação de software para acompanhamento de gestantes com sífilis(Universidade Brasil, 2020) Markus, Glaucya Wanderley Santos; Baptista, Alessandra; Magalhães, Daniel Souza FerreiraGestational syphilis is a worldwide problem and can be controlled through effective public health actions and measures. The objective of this study was to develop and evaluate a mobile application (app) in order to facilitate the monitoring of pregnant women with syphilis during the prenatal period until the postpartum period. This is a technological production aimed at building a mobile application. The Gestisífilis app allows you to obtain treatment data for the pregnant woman, including data regarding the tests performed, clinical stage of the disease, therapeutic scheme, VDRL examination tracking during the 9 gestational months, through the generation of reports that can be accessed and sent via email. The data entered is password protected by the system administrator, safeguarding patients' privacy. The app was installed on 23 smartphones with the Android system, from different nurses, to assess the compatibility of the system, and to evaluate the functionality of the app. The user's profile and degree of satisfaction were assessed using a QUIS questionnaire (Questionnaire for User Interaction Satisfaction), which was applied by the Google Form platform. The downloads on different smartphones showed that the synchronization and sending of the app's data works correctly. The results of the questionnaire showed that the majority of the evaluators were women (82.6%), under the age of 30 years (47.8%), with a specialist title (87%) professional experience between 1-2 years ( 52%). Regarding the usability of the app, the results showed that there was no statistically significant difference between professionals with up to 2 years and more than 2 years of experience (p 0.05), with average and median scores very close to the maximum value (10) . We concluded that the Gestisífilis app showed efficiency in the reception and transmission of information and approval of usability by the evaluators and can be a great tool in the monitoring of pregnant women with syphilis.Item Tempo de permanência na Unidade de Terapia Intensiva e o uso de Redes Bayesianas como ferramenta de gestão(Universidade Brasil, 2020) Santos, Patrícia Couto Macedo dos; Baptista, Alessandra; Magalhães, Daniel Souza FerreiraThe lack of beds in intensive care units (ICU) is a public health problem. The length of stay in these units contributes to reducing bed turnover, which slows down the admission of other critical patients who end up receiving inadequate care, increasing hospital mortality rates. The general objective of this work is to statistically analyze the possible causal relationships using probabilistic inferences between factors related to the length of stay in an intensive care environment through the use of Bayesian Networks for management strategies and support to decision making. A retrospective study was carried out in the general ICU of Hospital Calixto Midlej Filho de Itabuna, with a qualitative and quantitative approach with 49 patients aged between 14 and 92 years. Data collection was performed through the patients' medical records via the hospital's audit department and / or Medical and Statistical File Service (SAME). The variables collected were: gender, age, APACHE II (English: Acute Physiology and Chronic Health Evaluation II), presence of mechanical ventilation, development of infection and length of stay in the unit. The collected data were inserted and tabulated in an Excel® spreadsheet. and used in the manufacture of Bayesian Networks (RB) using GeNIe 2.0 software. The results showed that gender, age, mechanical ventilation and APACHE II classification factors influence the length of stay in the ICU. Therefore, the use of Bayesian methods that, through probabilistic reasoning, have a good performance to work with causes and effects relationships, can be used as a tool to support management for decision making and optimization of the time spent in critical ICU patients.Item Efeito da fotobiomodulação e da cinesioterapia na expressão de índices hematológicos em pacientes com osteoartrose de joelho(Universidade Brasil, 2020) Rebelato, Fabio Luiz; Baptista, AlessandraPhotobiomodulation (PBM: English-photobiomodulation) is a treatment that involves the use of a monochromatic light source, non-thermal effect, which has been proposed in the treatment of patients with knee osteoarthrosis (OAJ), due to these analog, action effects anti-inflammatory and regenerative. However, the systemic effects of PBM, especially those referring to monomorphonuclear blood cells, are still unclear. The aim of this study was to evaluate the number of white series cells and the number of patients diagnosed with OAJ published through PBM and kinesiotherapy, associated or not. The number of cells in the white and platelet series of 28 patients, between 45 and 80 years old, were randomly divided into 4 groups: Kinesiotherapy Group (CG); PBM Group (GL); Cinesioterapia + PBM Group (GCL); and PBM + Cinesioterapia Group (GLC). All groups receive treatment 3 times a week on alternate days for 4 weeks. Groups using treatment with physical activity (CG, GLC and GCL) perform supervised exercises and groups using treatment with PBM (GL, GCL and GLC) receive 9 irradiation points (Therapy XT-DMC, São Carlos, Brazil - 808nm P = 100mW - 3J / point). The evaluations were performed before the start of treatment (AV0) and 48 h after the end of the 10th session (AV1). Our results show that the initial and final count is not the number of neutrophils, lymphocytes, monocytes and platelets, the GC, GCL and GLC do not significantly alter cell counts (p0.05). The GL showed a significant increase only in the monocyte count (p0.05) after 4 weeks of treatment. The comparison between cell relationships between lymphocytic neoplasms (RNL), monocyte lymphocytes (RML) and coated lymphocytes (RPL), did not significantly affect the use of any method used. However, an RML in the intergroup evaluation showed an increasing trend only in the group treated with PBM. Therefore, we can conclude that PBM alone, without OAJ treatment, was the only treatment capable of promoting white cell and platelet count, mainly in monocytes. And an RML relationship was also a single cellular relationship capable of differentiating the proposed procedures, suggesting that PBM alone can increase the inflammatory response, in the tests tested.Item Dermatite induzida por produtos de higiene das mãos no contexto da pandemia de Covid-19(Universidade Brasil, 2021) Almeida, Amanda Priscila; Nunez, Silvia Cristina; Navarro, Ricardo ScarparoThe COVID-19 pandemic ravaged the entire planet and important behaviors were reinforced by all health control agencies around the world, such as social distancing, the use of protective masks and hand hygiene, through washing with water and soap or application of alcohol gel. The aim of this study was to carry out an integrative review of the evidence in the literature on the characteristics of dermatitis induced by hand hygiene products in the context of the COVID-19 pandemic and to carry out a survey of information through a structured questionnaire on the behavior of the population and the hand hygiene care during 2020. An integrative review of articles was carried out, following the PICOS strategy, in Portuguese, English and Spanish, between December 2019 and April 2021, with the descriptors: contact dermatitis; hand dermatitis; hand disinfection; occupational dermatitis; occupational irritant hand dermatitis AND COVID-19; coronavirus; pandemic; pandemic; SARS-COV-2 with their corresponding terms in Portuguese and Spanish. The Boolean OR operator was applied between the terms. The search was performed in PubMed, MEDLINE, LILACS and Scielo databases. An electronic form was made available online to answer questions related to hand hygiene and cleaning habits within the context of the COVID-19 pandemic. According to the results, from the search for studies and with double and triple crossings, 557 articles were found, among these, 24 articles were selected related to the study topic. The answers to the questions were converted into numbers and the normality of the distribution of variables was tested using the Shapiro-Wilk test. The data obtained were analyzed by Student's t and Wilcoxon statistical tests and correlation analyzes were performed using the Pearson's Correlation Coefficient using the SPSS software (IBM SPSS Statistics for Windows, version 25.0.; IBM, Armonk, New York) in the interval 95% confidence. A total of 1027 responses to the questionnaire were obtained and it was observed that 21.4% of the participants had COVID-19 and 93% changed their hand hygiene habits after the pandemic, the habit of using alcohol gel was one of the biggest changes (83.1 %), 52.2% of the participants learned something new about cleaning their hands after the pandemic and 74.6% noticed a change in the skin on their hands after the onset of the pandemic. Among those interviewed, 8% had to seek medical help for problems with the skin on their hands. We can conclude that education measures on hand hygiene habits should persist as important public health actions and the quality of products used for hand hygiene should be a factor to be considered both by establishments that provide hygiene products and by purchased products by the users.Item Avaliação do conhecimento sobre fotobiomodulação dos fisioterapeutas no Brasil(Universidade Brasil, 2021) Arruda Neto, Euler; Nunez, Silvia CristinaPhysiotherapy is the profession that assesses, rehabilitates, prevents, recovers, as well as restores, develops, and conserves the individual's capacity through physical resources such as ultrasound, heat and light. Electrophysical resources are described and recommended in undergraduate courses and among these we find the use of low power lasers. Brazil is one of the countries with the most publications in the world in the area known as Photobiomodulation (PBM), however, it is not clear the access that physiotherapy clinicians have to the advances obtained in scientific research. The purpose of this study is to verify, through an electronic form, the knowledge of physical therapists enrolled in class councils about PBM in daily practice. An electronic questionnaire Google Form was developed, and it was sent by email, WhatsApp social networks, SMS, and printed forms were also distributed. The distribution started in the region of Goiás and the Federal District with the support of CREFITO 11 and then expanded to other regions. In total 106 physiotherapists answered the questionnaire. Of these 50% used lasers in the clinic, while 10.4% had never used lasers. After obtaining the data and according to the responses obtained, we observed 50% that physiotherapy professionals. 81.4% said they did not use it because they did not have the equipment and 10.2% indicated the cost as a reason for not using it. Among the participants, 62.3% said they had not made any updates in the area in the last 3 years and of those who said they had updated the courses up to 1 hour in duration were the majority. 76.5% also never calibrated their equipment and 45.7% said they used the protocols they learned at graduation. Based on the results, we conclude that there is a need for greater dissemination of the scientific knowledge obtained in the field of PBM in physical therapy so that the advances are effectively passed on to professionals who work clinically in the area.
