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 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 Avaliação da descontaminação de máscaras de proteção facial utilizando radiação UV-C(Universidade Brasil, 2022) Mota, Mara Soares de Almeida; Navarro, Ricardo Scarparo; Baptista, AlessandraInfectious respiratory diseases (IRD) are predominantly transmitted by airborne droplets or aerosols between people with close interactions. IRDs have a high rate of mortality and transmission between populations. The use of face protection masks (FPM) are effective in reducing the transmission of IRDs. Different methods are used for surface decontamination. The physical method of decontamination with UV-C radiation has shown effective results in different areas. The aim of this in vitro study was to evaluate FPM decontamination using UV-C radiation. Quadrangular samples from the masks were contaminated with a suspension of 108 CFU/ml of E. coli, in exponential phase, with the aid of a spray bottle inside the laminar flow. Three types of masks were evaluated (n=9): Tricoline (cotton) (T), Surgical (S) and N95 (N) at different times of UV-C irradiation, with portable SURFACE UV® equipment (MMOptics, São Carlos, Brazil, ƛ= 254 nm), the distance of 1 cm from the surface of the samples, scanning mode, at times of 30s, 45s and 60 s. To evaluate the microbial reduction, the samples were immersed in a test tube containing sterile saline solution, submitted to mechanical agitation for microbial recovery, and subsequently performed serial dilutions in the order of 1:10. Aliquots of the suspensions were seeded on Mueller Hinton agar for final microbial counts. The experiment was carried out in triplicate. All data were analyzed for their distribution by the Shapiro-Wilk test. Parametric data were analyzed by ANOVA and Tukey test. Nonparametric data were analyzed using the Kruskal-Wallis and Wilcoxon test (p< 0.05). The study showed that UV-C radiation promoted effective decontamination of different models of FPM contaminated with E. coli. In Tricoline and Surgical the microbial reduction was observed in the time of 30 s and total decontamination in the times of 45 s and 60 s. In N95, total decontamination was observed at all irradiation times. The type of face protection mask influenced the effects of UV-C. The UV-C irradiation from 30 s onwards reduced the microbial load and from 45 s onwards promoted total decontamination in all types of masks tested.Item Avaliação de equipamento portátil na desinfecção rápida de diferentes tipos de máscaras faciais(Universidade Brasil, 2022) Souza, Helen Patrícia de Oliveira Duarte; Baptista, AlessandraThe use of masks to minimize environmental transmission of pathogens has been one of the main strategies to protect health professionals and the general population in times of airway-transmitted diseases. The aim of this in vitro study was to evaluate the efficacy of ultraviolet light (UV-C), with different exposure times, in microbial reduction in diverse types of face masks: tricoline, surgical and N95. The masks were contaminated with 108 UFC/mL suspension of Staphylococcus aureus, with the aid of a spray and submitted to UV-C light exposure, by means of portable equipment (254 nm). Irradiation was performed at 1 cm from the samples, in sweep mode, for 30 s, 45 s and 60 s. To evaluate microbial reduction, pieces of the masks, about 1 cm2 were placed in a test tube containing sterile saline solution and submitted to mechanical agitation, before and after disinfection procedures. To facilitate the final counting, serial dilutions were performed in the order of 1:10, and 10 µL of the suspensions were seeded in Mueller Hinton agar for the final microbial count. All data were analyzed on its distribution using the Shapiro-Wilk test. Parametric data were analyzed using the ANOVA test, followed by the Tukey test. Non-parametric data were analyzed using the Kruskal-Wallis test, followed by the Wilcoxon test. The significance level was considered for p<0.05. The use of UV-C radiation promoted effective microbial reduction in face protection masks, contaminated with S. aureus, in the three models of face protection masks tested in this study (p>0.05) and even 60 s of irradiation was more effective in all types of masks. However, the types of face protection masks evaluated in this study did not influence the effectiveness of disinfection promoted by irradiation with UV-C light, at any irradiation time tested (p<0.05). Therefore, we can conclude that the use of UV-C radiation can promote effective microbial reduction in face protection masks, contaminated with S. aureus, in the three models of masks tested in this study: Tricoline, Surgical and N95, and the microbial reduction is density of dependent energy.Item Avaliação dos efeitos da auriculoterapia e auriculoterapia a laser no tratamento das alterações de olfato e paladar pós Covid-19 - estudo clínico(Universidade Brasil, 2023) Oliveira, Andreia de; Navarro, Ricardo Scarparo; Baptista, AlessandraCOVID-19 is an infectious disease caused by the new coronavirus, also known as severe acute respiratory syndrome virus 2 (SARS-CoV-2). There are characteristic systemic changes during the disease process, and post-COVID-19, called long COVID, we can highlight the sensory changes in smell and taste that directly interfere with individuals' quality of life. The objective of the study was to evaluate the effects of auriculotherapy (AT) and laser auriculotherapy (LAT) in the treatment of post-COVID- 19 changes in smell and taste. After approval by the CEP (5,357,603), acceptance and signing of the TCLE by the participants, with a positive PCR exam or self-test for COVID-19, treated, aged over 18 years, of both sexes, were randomly divided into groups : G1 (AT) (n=12) AT with mustard seeds; G2 (LAT) (n= 12) AT with low power laser (Laser Duo, MMOptics, São Carlos, Brazil) (808 nm, 3 J, 100 mW, 30 s, tip area 0.03 cm2, 3.33 W/cm2, 100 J/cm2); G3 (LAT placebo) (n= 12) LAT as in group 2, with a barrier at the exit of the laser beam emission; G4 (LAT tip) (n= 12) as in group 2, using acupuncture tip (808 nm, 3 J, 100 mW, 30 s, tip area 0.07 cm2, 1.43 W/cm2, 42.9 J/cm2) (MMOptics, São Carlos, Brazil). In all groups, AT was performed in contact with the skin on the ear at different acupoints (Shen Men, Kidney, Sympathetic, Tongue, Mouth, External Nose, Internal Nose/Pharynx, Heart, Lung), once a week, totaling 10 sessions. Participants were evaluated by anamnesis, Sensory Assessment Tests (SAT) of Smell and Taste before and after each session. The results showed for SAT smell and taste in the intragroup analysis in G1-AT, G2-LAT and G4-LAT tip there was a significant difference before and after treatments (p<0.05), in G3-LAT placebo smell there was no difference for sweet and salty (p>0.05) and there was a difference for bitter, sour, spicy (p>0.05); in G3-LAT placebo taste there was no significant difference (p>0.05) for all variables. For the intergroup analysis for SAT smell and taste: between the auriculotherapy groups (G1 AT, G2 LAT, G4 LAT tip) and G3 LAT placebo there were significant differences (p<0.05), between the auriculotherapy groups they were no differences (p>0.05) and the treatments promoted an effective increase in smell and taste values (p<0.05), the G3 LAT placebo group presented lower results than the treatments groups. It can be concluded that auriculotherapy and laser auriculotherapy were effective in treating changes in smell and taste after COVID-19; the different modalities of auriculotherapy - AT, LAT, LAT tip promoted recovery of smell and taste, with no differences between treatments; there were no placebo effects, the study proposes new therapeutic protocols of auriculotherapy and laser auriculotherapy in the treatment of changes in smell and taste after COVID-19; no side effects, non- pharmacological, non-invasive, painless, with greater patient acceptability.Item Avaliação in vitro dos efeitos de diferentes terapias antimicrobianas em canais uniradiculares infectados com Candida Albican(Universidade Brasil, 2022) Rossi, Roberta Mirandola Mile; Baptista, AlessandraContamination of the root canal system is one of the main complications in endodontic treatment, where the necrotic pulp does not have blood vessels that can transport defense cells and antibiotics to the site. The aim of this study was to evaluate, in vitro, the fungal reduction of root canals treated with different antimicrobial therapies. Fifty-four bovine teeth were previously prepared for the manufacture of standardized single-root canals, with previous instrumentation with Hedströen files (Denstsplay®) #35, pre-enlarged with Gattes Gliden #4 drills (Denstsplay®) and instrumentation throughout its length with Reciproc R 50–25 mm files, using mechanized instrumentation with reciprocating movements. Then the root canals were contaminated with Candida albicans and submitted to different antimicrobial therapies: irrigation with 1% sodium hypochlorite for 5 min (GH); irrigation with 0.2% chlorhexidine for 5 min (GCHX); photodynamic therapy (aPDT antimicrobial Photodynamic Therapy), mediated by methylene blue (0.005%) and low power laser (Laser Duo, MMO, São Carlos, Brazil,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 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 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 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 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 Efeitos da Fotobiomodulação no processo de cicatrização da lesão por pressão(Universidade Brasil, 2022) Oliveira, Laricy Rodrigues de; Baptista, AlessandraCurrently, the prevention and treatment of Pressure Ulcer (PU) is the focus of multidisciplinary actions in different health care settings. Photobiomodulation is a form of phototherapy proposed in the treatment of PU, as it is able to modulate the quality and speed of the healing process. The objective of this study was to evaluate the quality of life (QoL) of the individual affected by PU, as well as to evaluate the modulation of the PU healing process, through photobiomodulation. This is a qualitative-quantitative clinical study, in which 10 volunteers with PU participated, treated at home. Participants were randomly divided into two groups, according to the therapeutic intervention: Control Group (n=5); treated with calcium and sodium alginate coating and Photobiomodulation Group (n=5); treated with photobiomodulation, where the PUs received punctual irradiation, 4J/point, on alternate days, with a low power laser emitting at 660 nm, with 100 mW of power, for 40 s. All volunteers in this study received treatment for 4 weeks. Participants QoL was analyzed using the WHOQOL-BREF questionnaire, before and after the interventions. The PU healing process was evaluated by the PUSH instrument, on the 1st, 15th and 29th days. The PUs were photographed in a standardized way, on the respective days, to compare the evolution of the repair process. For data analysis, the Shapiro Wilk normality test and the two way ANOVA test of variance were applied, and the means were compared using the Tukey test with a significance of 5%, being considered statistically different when p<0.05. The perception of QoL in the Photobiomodulation Group was regular in the initial phase of treatment, evolving to very good in the final phase, while the volunteers in the Control Group maintained a very good response from the beginning to the end of the treatment. The evaluation using the PUSH instrument showed a gradual temporal improvement in the PU repair process, regardless of the treated group. The comparison of photographic images revealed that there was a reduction in the staging of PUs in both groups. Therefore, we can conclude that photobiomodulation, in the parameters tested in this study, can be a good alternative in relation to QoL and modulation of the PU healing process.Item Luz UV-C na descontaminação de diferentes superfícies(Universidade Brasil, 2021) Soares, Roseane Débora Barbosa; Baptista, AlessandraItem Presença de canais mesio mediais em primeiros molares inferiores: um estudo tomográfico(Universidade Brasil, 2020) Dantas, Raphaela Rodrigues; Baptista, AlessandraRecognizing variations in the anatomy of the root canal is essential for a successful diagnosis and successful endodontic treatment. The objective of this study was to identify the incidence of the middle mesial canal in the lower first molars, through Cone Beam Computed Tomography. The sample consisted of 200 tomographic examinations of lower first molars used from the tomographic image file of aradiology clinic in the city of Itabuna-BA. No patient was submitted to the examination for the purpose of research. CT scans were purchased on the i-Cat Classic ® device (Imaging Science International, Hatfield, Pennsylvania, United States of America) with voxel between 0.4-0.2 mm, and image acquisition and analysis were formed using XoranCat software , version 3.0.34 (Xoran Technolo-gies, Ann Arbor, MI). The identification of the middle mesial canal, as well as its location and union with adjacent canal, was determined by multiplanar reformatting (MPR) in axial reconstruction. All analyzes were performed in the R Core Team program (2018), with a significance level of 5%. The prevalence of patients with middle mesial canal in lower first molars was 8.0% (16 molars), with no significant association between the presence of anatomical variation with sex and age. Of the 16 molars, five (31.2%) were mesialized, nine (56.3%) centralized and two (12.5%) were distalized. In addition, 68.8% had union of the root thirds. Therefore, It can be concluded then that the study of the presence of the middle mesial canal, in populations from different locations, is extremely important to assist the dentistry in the diagnosis and planning of the success of the endodontic treatment. This study was carried out in the city of Itabuna-BA and showed a low prevalence of the medial mesial canal in the evaluated population, with no significant association between the presence of anatomical variation with sex and age.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 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.
