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.Item Fotobiomodulação no manejo da mucosite oral em hospitais do Brasil: a busca por uma diretriz clínica(Universidade Brasil, 2022) Passos, Januaria Lima Ribeiro; Nunez, Silvia CristinaCancer is one of the most frequent diseases worldwide. Oral mucositis (OM) is a common and debilitating complication of chemotherapy (CT), head and neck radiotherapy (RT) and hematopoietic stem cell transplantation (HSCT). Photobiomodulation (PBM) IS one of the therapeutic alternatives for prevention and treatment of OM. The objective of this study was to carry out a survey of data from the protocols applied for PBM in public and private hospitals in Brazil. A cross-sectional, quantitative study was carried out with the application of questionnaires to dentists, built specifically to understand the establishment of protocols and their outcomes, to verify if there is a consensus on the use of PBM in OM in Brazil. According to the analysis of the results, we observed that dentists work both in public and private hospitals in Brazil and most of them are employed by the institution. The PBM protocols, as well as, the initial assessment of patients, are performed by the dental surgeon who claims to use protocols based on scientific evidence. More modern equipment’s with 100 mW of power are the most used ones and, according to the interviewees, frequently checked. For OM induced by QT and HSCT, preventive and therapeutic protocols were cited, while for RT only one protocol was cited. The prevailing wavelength was red, and only for therapeutic HSCT the 2 wavelengths had the same frequencies. In all cases, energies of 1 and 2 J were the prevailing ones, with irradiation performed in a punctual way. The frequency of irradiation depends on the duration of RT, or it is performed for 5 days in a week for QT and HSCT, and only in therapeutic HSCT did the interviewees point out the symptomatology and the clinical aspect as relevant for the choice of treatment. According to our results, the treatment of OM with PBM presents constancy of energy and form of application, which may explain its spread and successful application in different regions of the country in a homogeneous way.Item Ensaio clínico cego e randomizado para avaliação de dois protocolos de Fotobiomodulação para a prevenção das complicações orais em pacientes transplantados de medula óssea(Universidade Brasil, 2021) Marski, Roberta Silveira da Silva; Nunez, Silvia CristinaBone marrow transplantation (BMT) or hematopoietic cell transplantation requires high doses of chemotherapy in patients who will undergo HSCT (Hematopoietic Stem Cell Transplantation), this chemotherapy regimen causes the destruction of cells with a high mitotic index leading to damage to the oral and gastric mucosa called Mucositis. The aim of this study was to investigate the efficacy of Photobiomodulation (PBM) in the prevention of oral complications in hematopoietic transplant patients applying PBM daily and comparing it to the application every other day, totalizing 4 weekly applications from the beginning of conditioning to neutrophilic engraftment (bone marrow engraftment) in gender-independent, halogen and/or haploidentical transplant recipients. The volunteers were randomly divided into 2 groups: Daily Laser Group (DLG) P=13; LG4 (4x a week) P=17. All groups were evaluated daily by a trained nursing staff., from the beginning of conditioning D-7 to D+21, the results were cataloged and analyzed in a blind, longitudinal study, according to the WHO scale for evaluation of oral mucositis and pain degree (VAS scale). The groups were submitted to low power laser treatment (Therapy XT-DMC, São Carlos, Brazil) with a wavelength of 660nm, Power of 100mW, exposure time of 20 s delivering 2J per point throughout the oral cavity. Data related to xerostomia, odynophagia and degree of mucositis were analyzed over 21 days and the data were compared statistically using the Mann-Whitney test. The statistical comparison results for xerostomia (D+8 p=0.4434), odynophagia (D+8 p=0.8560) and mucositis (D+8 p=0.7285) showed no significant differences at any time during the study. According to the results, the PBM protocol on alternate days is as efficient as the daily application for the prevention of oral complications in patients who underwent HSCT.Item Avaliação da fototerapia com diferentes comprimentos de onda no tratamento da Alopécia androgenética(Universidade Brasil, 2024) SILVA, Leandro Ferreira da; BAPTISTA, AlessandraAndrogenetic alopecia (AGA) is a hair dysfunction that promotes the transformation of terminal hairs into vellus hairs and consequent baldness. Phototherapy (FT) uses light, usually laser or LED, to stimulate, heal and/or regenerate damaged tissues and has been identified as a safe and promising resource for the treatment of AGA. The purpose of this study is to compare different wavelengths in the treatment of AGA. 10 volunteers were selected, randomly divided into 2 groups: Red Light Group (GLV, n=5) and Blue Light Group (GLA, n=5). The groups received point irradiation (4J/point), respectively, with the Venus equipment (MMOptics, São Carlos, Brazil), GLV (l= 660nm, P= 100 mW, for 40 s) and GLA (l= 440 nm, P = 150 mW, for 26.6 s). The interventions were carried out once a week, for 90 days, totaling 12 treatment sessions. The emergence of new hairs was analyzed by comparing the photographic record before any intervention (T1) and at the end of treatment (T2). The relationship between vellus threads and terminal threads was analyzed by trichoscopy with polarized light, before and at the end of treatment. A specific quality of life assessment questionnaire for androgenetic alopecia (Women's Androgenetic Alopecia Quality of Life Questionnaire -WAA-QoL) before and after the end of the interventions. The results showed that both red light and blue light, in the parameters tested in this study, led to an increase in the number of terminal strands after treatment (p< 0.05), which allowed a reduction in the central parting of the treated hair. The evaluation of the WAA-QoL questionnaire showed a lower percentage of responses with a higher degree of dissatisfaction after both treatments. Therefore, we can conclude that the use of phototherapy is an effective therapeutic resource in the treatment of AGA with red or blue light, in the parameters tested in this study.Item A relação entre a irradiação transcutânea do sangue – ILIB modificada e os níveis de cortisol salivar em cuidadores de idosos saudáveis(Universidade Brasil, 2021) Trindade, Monaiza Moura; Baptista, AlessandraFormal caregivers usually have exhaustive work scale that can trigger emotional changes and a decrease in the quality of life of these professionals. The use of ILIB (Intravascular Laser Irradiation of Blood) can improve the immunological activity of the blood, in addition to facilitating blood circulation and has been used in the treatment of different diseases. The aim of this study was to verify the effects of ILIB, applied transcutaneous, in relation to the levels of salivary cortisol of caregivers of formal elderly in long-term care institutions, who work during the day and night. Forty-two caregivers of formal elderly people were divided into 6 groups: Day Group (DG) (n=7); Day ILIB Group (DILIBG) (n=7); Day ILIB/placebo group (DPG) (n=7); Night Group (NG) (n=7); ILIB Night Group (NILIBG) (n=7); and Night ILIB/placebo Group (NPG) (n=7). Volunteers in the ILIB and ILIB / placebo groups received ILIB, in the radial artery region, by means of a low-power laser (Laser Duo, MMOPTICS, São Carlos, Brazil), l= 660 nm, P = 100 mW / 30 min, every other day, for 2 weeks, totaling 8 sessions of treatment/placebo, while the groups: GD and GN performed salivary collection on the day off and on the workday. All participants answered the quality of life questionnaire (QLQ) before any procedure and saliva collections for volunteers in the ILIB and ILIB/placebo groups were performed before any procedure; 24 h and 48 h after 8 treatment/placebo sessions, while the groups: DN and NG performed salivary collection on the day off and on the workday. The QLQ results did not show statistically significant differences between daytime and nighttime workers (p>0.05). Regarding cortisol quantification, the results showed statistically significant decreases (p<0.05) in salivary cortisol levels, both in the ILIB groups and in the placebo groups. Therefore, we can conclude that it was possible to measure the salivary cortisol levels of caregivers of formal elderly in long-stay institutions, who work day and night, treated or not with ILIB. However, ILIB cannot help to reduce salivary cortisol levels in caregivers of elderly people in long-term care facilities.Item A relação entre a irradiação transcutânea do sangue – ILIB modificada e os níveis de cortisol salivar em cuidadores de idosos saudáveis(Universidade Brasil, 2021) Trindade, Monaiza Moura; Baptista, AlessandraFormal caregivers usually have exhaustive work scale that can trigger emotional changes and a decrease in the quality of life of these professionals.
