RESUMO

This study aimed to investigate a new implantation site (intra-auricular subcutaneous - IA) compared to intramuscular (IM) in the cervical portion (cervical splenius muscle) of the neck for ovarian transplantation in goats. Morphological aspects of the implant, follicular activation and morphology, and type I and III collagen deposits of the transplanted tissue were evaluated. Four fragments of the ovarian cortex were allotransplanted at the IA and IM sites in all goat recipients and recovered 7 (IA-7; IM-7) or 15 (IA-15; IM-15) days later and submitted to histological analysis. Two fragments/animal were separated for the fresh control (FC) group. There was a higher percentage of normal and developing primordial follicles at the IA-7 site (P < 0.05) compared to the other treatments, with similar values to the fresh control. Type I and III collagen fibers differed between the groups (P < 0.05), showing a considerable decrease in type I collagen fibers at the IA-7 site compared to the FC. However, the IM-7 and IA-15 sites showed higher values of type I collagen fibers, showing similarity to the FC. Therefore, we conclude that the IA site in goats is an effective site for ovarian tissue transplantation, as it is easily accessible, low invasive and has presented satisfactory rates of morphology and follicular activation.

RESUMO

BACKGROUND: Autologous hematopoietic stem cell transplant (HSCT), characterized by high intensity chemotherapy followed by the infusion of HSC previously collected from the peripheral blood, is a procedure used in the treatment of several malignancies. In pediatrics, the apheresis procedure represents a challenge, due to the need for insertion of a rigid central venous catheter (CVC) in small children. The CVC is usually used for stem cell collection and then removed. Later, the patient will need a new device for cell infusion. AIM: We propose the use of one single catheter for both apheresis and infusion. METHODS: We present five children between 1 and 13 years of age who underwent apheresis using a high flow PICC catheter surgically inserted. RESULTS: All patients utilized a PICC line double lumen 5Fr (PowerPICC™ 5Fr DL BARD/USA) placed in the brachiocephalic vein tunneled on the chest, inserted under 24 h prior to apheresis to assure the devices were pervious. Three of the patients were diagnosed with solid tumor and one with acute lymphoblastic leukemia (ALL) awaiting Car-T Cell therapy. The four children who underwent autologous HSCT used the same catheter for cell infusion and remained with the catheter following discharge. The child who was submitted for Car-T Cell still awaits infusion and the catheter was removed. CONCLUSIONS: High flow PICC is a viable alternative for apheresis to maintain an adequate flow of 5 ml/s and can be used as a single catheter throughout the HSCT process, reducing the risks from anesthesia and the catheter insertion procedure. TYPE OF STUDY: Clinical Research.

RESUMO

Background: CrossFit is characterized by a diverse range of exercises recruiting different muscles and requiring different muscle functions. A characterization of muscular performance parameters in this population is needed. Purpose: To determine reference values for various aspects of muscular performance of muscles of the trunk, thigh, hip, and mass grasp in CrossFit participants. Also, this investigation aimed to compare the strength measures between male and female CrossFit participants, as well as between dominant and non-dominant limbs. Design: Descriptive, Cross-sectional. Setting: Laboratory. Methods: Isometric strength of trunk extensors (TE) and mass grasp was measured with handheld and Jamar dynamometer respectively. An isokinetic dynamometer was used to assess the muscle performance of the knee flexors (KF) and extensors (KE) (at 60º/s and 300º/s), and hip flexors (HF), extensors (HE), and abductors (HA) (60º/s and 240º/s ). Reference values for torque, work, power, fatigue, flexor:extensor ratio for the knee (hamstring:quadriceps - H:Q) and hip (HF:HE) joints were calculated. The torque and work values were normalized by the body mass. Mixed multivariate and univariate analyses of variance and independent t-tests were used for statistical analyses to compare between sexes and limbs. Results: Participants included 111 individuals (58 males and 53 females) with at least one year of experience in CrossFit. Normative data are provided for the outcome variables. Males had greater values of muscular performance parameters than females in most variables (p<0.05). Also, the dominant limb had greater mass grasp strength (p<0.002), greater KE power at 60º/s (p=0.015), lower H:Q ratio at 60º/s (p=0.021) and 300º/s (p=0.008), and lower KE fatigue (p=0.002). Conclusion: This study provides reference values for the trunk extensors, mass grasp, knee, and hip muscle performance in male and female CrossFit practitioners. Their muscle performance profile was characterized by few inter-limb asymmetries, and males demonstrated greater muscular performance outcomes than females, even after normalization by body mass. These reference values can be used for comparisons in research and clinical settings. Level of Evidence: 3b.

RESUMO

INTRODUCTION: The immune reconstitution (IR) after the allogenic hematopoietic stem cell transplantation (allo-HSCT) is a progressive process intrinsically correlated to the therapeutic success. It is essential to understand the interfering factors in IR to prevent the HSCT-related mortality. METHODS: We retrospectively evaluated the clinical outcomes, absolute lymphocyte counts (ALCs) and lymphocyte subtypes at different time-points of 111 pediatric patients with allogeneic HSCT for malignant and non-malignant diseases from 2013 to 2018. RESULTS: The ALCs gradually increased on D+30, D+100, and D+180 (medians 634/µL, 1022/µL and 1541/µL, respectively). On D+100, the CD3+CD8+ achieved the highest recovery rate (68%), followed by the CD16+CD56+ (47%), CD3+CD4+ (39%) and CD19+ (8%). The adequate ALC recovery was associated with age < 8 years, bone marrow grafts, myeloablative conditioning, non-use of serotherapy and non-haploidentical donors. The ALC and CD3+CD8+ on D+100 counts were higher in patients with the cytomegalovirus infection. The CD3+CD4+ recovery was associated with an age < 8 years, a non-malignant disease and a lower incidence of acute graft-versus-host disease ≥ grade 2. Furthermore, the ALC recovery on D+100 resulted in a higher overall survival, regardless of the disease type (HR 3.65, 1.05 - 12.71, p = 0.04). CONCLUSION: Several factors influenced the IR after the allo-HSCT. The ALC ≥ 500/µL on D+100 was a simple IR predictor of survival, easily available to resource-limited centers.

RESUMO

This study investigated whether blood-based biomarkers were related to functional test performance and respiratory muscle strength in older adults with COPD and sarcopenia. The participants included in this cross-sectional study were from both sexes and sixty years or older. Based on clinical assessment, participants were categorized in COPD (n = 43) and non-COPD (NCOPD) (n = 43) groups. They were also assessed for body composition and muscular mass by dual-energy X-ray absorptiometry, using the relative skeletal muscle index for the diagnosis of sarcopenia. A series of functional tests, including short physical performance battery (SPPB), 6-minute walking test (6MWT), maximal inspiratory and expiratory pressures (MIP and MEP), were carried out. Plasma levels of myokines (Irisin and BDNF), and soluble TNF receptors (sTNFR1 and sTNFR2) were determined by ELISA. In the multivariate analysis, 6MWD was associated with age, COPD-related sarcopenia and BDNF (R2 = 0.29; f2 = 0.41). SPPB score was associated with COPD-related sarcopenia and sTNFR1 (R2 = 0.25; f2 = 0.33). MIP value was associated with sex, COPD-related sarcopenia, sTNFR2 and Irisin (R2 = 0.24; f2 = 0.31). Finally, MEP value was associated with sex COPD-related sarcopenia (R2 = 0.18; f2 = 0.22). Plasma levels of myokines and inflammatory markers are related with functional and respiratory performance in older adults with COPD and sarcopenia.

RESUMO

The incidence of pediatric adrenocortical tumors (ACT) is high in southern Brazil due to the founder TP53 R337H variant. Neonatal screening/surveillance (NSS) for this variant resulted in early ACT detection and improved outcomes. The medical records of children with ACT who did not participate in newborn screening (non-NSS) were reviewed (2012-2018). We compared known prognostic factors between the NSS and non-NSS cohorts and estimated surveillance and treatment costs. Of the 16 non-NSS children with ACT carrying the R337H variant, the disease stages I, II, III, and IV were observed in five, five, one, and five children, respectively. The tumor weight ranged from 22 to 608 g. The 11 NSS children with ACT all had disease stage I and were alive. The median tumor weight, age of diagnosis, and interval between symptoms and diagnosis were 21 g, 1.9 years, and two weeks, respectively, for the NSS cohort and 210 g, 5.2 years, and 15 weeks, respectively, for the non-NSS cohort. The estimated surveillance/screening cost per year of life saved is US$623/patient. NSS is critical for improving the outcome of pediatric ACT in this region. Hence, we strongly advocate for the inclusion of R337H in the state-mandated universal screening and surveillance.

RESUMO

Whole-body vibration (WBV) exercises have recently been introduced as a nonpharmacological therapeutic strategy for sarcopenic older people. The present study aimed to evaluate the effect of WBV exercise on hemodynamic parameters in sarcopenic older people. Forty older people, divided into groups of nonsarcopenic (NSG = 20) and sarcopenic (SG = 20), participated in the study and were cross randomized into two interventions of eight sets of 40 s each, these being squatting with WBV and squatting without WBV. Heart rate (HR), peak heart rate (peak HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), double product (DP), mean arterial pressure (MAP), and subjective perception of effort (SPE), were assessed at baseline, during, and after a single WBV session. The HR, peak HR, and DP variables were similar at baseline between groups. WBV exercise increased all the hemodynamic parameters both during and immediately after the intervention, in both groups (SG and NSG). The MAP values were similar at baseline between groups; however, in the NSG there was a significant increase during and immediately after the squatting with WBV intervention (p < 0.05). The HR behavior, in both groups, showed that there was an increase in HR after the first set of exercises with vibration and this increase was maintained until the final set. The absence of adverse effects of WBV exercise on the cardiovascular system and fatigue suggests this exercise modality is adequate and safe for sarcopenic older people.

RESUMO

Severe aplastic anemia (SAA) is a life-threatening disease that can be cured with allogeneic cell transplantation (HCT). Haploidentical donor transplantation with post-transplantation cyclophosphamide (haplo-PTCy) is an option for patients lacking an HLA-matched donor. We analyzed 87 patients who underwent haplo-PTCy between 2010 and 2019. The median patient age was 14 years (range, 1 to 69 years), most were heavily transfused, and all received previous immunosuppression (25% without antithymocyte globulin). Almost two-thirds (63%) received standard fludarabine (Flu)/cyclophosphamide (Cy) 29/total body irradiation (TBI) 200 cGy conditioning, and the remaining patients received an augmented conditioning: Flu/Cy29/TBI 300-400 (16%), Flu/Cy50/TBI 200 (10%), or Flu/Cy50/TBI 400 (10%). All patients received PTCy-based graft-versus-host disease (GVHD) prophylaxis. Most grafts (93%) were bone marrow (BM). The median duration of follow-up was 2 years and 2 months. The median time to neutrophil recovery was 17 days. Primary graft failure occurred in 15% of the patients, and secondary or poor graft function occurred in 5%. The incidences of grade II-IV acute GVHD was 14%, and that of chronic GVHD was 9%. Two-year overall survival and event-free survival (EFS) were 79% and 70%, respectively. EFS was higher for patients who received augmented Flu/Cy/TBI (hazard ratio [HR], .28; P = .02), and those who received higher BM CD34 cell doses (>3.2 × 10E6/kg) (HR, .29; P = .004). The presence of donor-specific antibodies before HSCT was associated with lower EFS (HR, 3.92; P = .01). Graft failure (HR, 7.20; P < .0001) was associated with an elevated risk of death. Cytomegalovirus reactivation was frequent (62%). Haploidentical HCT for SAA is a feasible procedure; outcomes are improved with augmented conditioning regimens and BM grafts with higher CD34 cell doses.

RESUMO

The survival rates of children with high-risk acute myeloid leukemia (AML) treated with hematopoietic stem cell transplant (HSCT) range from 60% to 70% in high-income countries. The corresponding rate for Brazilian children with AML who undergo HSCT is unknown. We conducted a retrospective analysis of 114 children with AML who underwent HSCT between 2008 and 2012 at institutions participating in the Brazilian Pediatric Bone Marrow Transplant Working Group. At transplant, 38% of the children were in first complete remission (CR1), 37% were in CR2, and 25% were in CR3+ or had persistent disease. The donors included 49 matched-related, 59 matched-unrelated, and six haploidentical donors. The most frequent source of cells was bone marrow (69%), followed by the umbilical cord (19%) and peripheral blood (12%). The 4-year overall survival was 47% (95% confidence interval [CI] 30%-57%), and the 4-year progression-free survival was 40% (95% CI 30%-49%). Relapse occurred in 49 patients, at a median of 122 days after HSCT. There were 65 deaths: 40 related to AML, 19 to infection, and six to graft versus host disease. In conclusion, our study suggests that HSCT outcomes for children with AML in CR1 or CR2 are acceptable and that this should be considered in the overall treatment planning for children with AML in Brazil. Therapeutic standardization through the adoption of multicentric protocols and appropriate supportive care treatment will have a significant impact on the results of HSCT for AML in Brazil and possibly in other countries with limited resources.

RESUMO

Allogeneic hematopoietic stem cell transplantation (HCT) can cure primary immunodeficiency diseases (PID). When a HLA-matched donor is not available, a haploidentical family donor may be considered. The use of T cell-replete haploidentical HCT with post-transplantation cyclophosphamide (haplo-PTCy) in children with PID has been reported in few case series. A donor is usually readily available, and haplo-PTCy can be used in urgent cases. We studied the outcomes of 73 patients with PID who underwent haplo-PTCy, including 55 patients who did so as a first transplantation and 18 who did so as a salvage transplantation after graft failure of previous HCT. The median patient age was 1.6 years. Most of the children were male (n = 54) and had active infection at the time of transplantation (n = 50); 10 children had severe organ damage. The diagnosis was severe combined immunodeficiency (SCID) in 34 patients and non-SCID in 39 (Wiskott-Aldrich syndrome; n = 14; chronic granulomatous disease, n = 10; other PID, n = 15). The median duration of follow-up of survivors was 2 years. The cumulative incidence of neutrophil recovery was 88% in the SCID group and 84% in non-SCID group and was 81% for first transplantations and 83% after a salvage graft. At 100 days, the cumulative incidence of acute GVHD grade II-IV and III-IV was 33% and 14%, respectively. The majority of patients reached 200/µL CD4+ and 1000/µL CD3+ cell counts between 3 and 6 months. The estimated 2-year overall survival was 66%; it was 64% for SCID patients and 65% for non-SCID patients and 63% for first HCT and 77% for salvage transplantations. Twenty-five patients died, most of them due to infection early after transplantation (before 100 days). In conclusion, haplo-PTCy is a feasible procedure, can cure two-thirds of children with PID, and can be used as rescue treatment for previous graft failure. © 2020 American Society for Transplantation and Cellular Therapy.

RESUMO

OBJECTIVES: The aim of this study was to analyze the outcomes of children with Diamond-Blackfan anemia (DBA) treated in Brazil with hematopoietic cell transplantation (HCT). METHODS: We performed a retrospective analysis of 44 pediatrics patients transplanted between 1990 and 2018. The median age of patients was 5 years, and 57% were male. Twenty-five received their first HCT from an HLA-matched sibling donor (MSD), 12 from a HLA matched unrelated bone marrow donor (MUD 10/10, n = 12) and 7 other HLA mismatched donors (MMD). RESULTS: After a median follow-up of 4 years, estimate 5-year overall survival (OS) for the entire cohort was 70%, 80% for MSD group, 73% for MUD, and 29% for MMD. Thirty-eight out of the 44 evaluable patients engrafted successfully. Primary and secondary graft failure was observed in five and three patients, respectively. Rates of grade II-IV and III-IV acute graft-versus-host disease (aGVHD) were 25% and 18%, respectively. Nine patients developed chronic GVHD (cGVHD). CONCLUSION: Overall survival rates observed after HLA matched donors transplant for DBA were comparable to those reported from higher-income countries and international registries.

RESUMO

The aim of this study was to investigate the effect of using different reforestation woods (Acacia mearnsii and Eucalyptus citriodora) on the formation of volatile organic compounds and to evaluate the changes in the lipid fraction (peroxide value and thiobarbituric acid reactive substances), microbiological counts and overall liking in bacons stored for 60 days at 5 ± 1 °C. Smoking with Eucalyptus citriodora wood increased the total phenolic content and, consequently, reduced the concentration of hexanal, TBARS, and PV values. Although smoking with different reforestation woods did not impact negatively on the liking of products, no changes on antimicrobial activity was observed in the developed products. Thus, the use of Eucalyptus citriodora wood may be an alternative for smoking meat products as it reduced lipid oxidation and improved the volatile compounds profile, and provided higher antioxidant activity. The information generated herein can be used as a platform for companies to test the viability of producing meat products smoked with reforestation woods.

RESUMO

RESUMO Objetivo Comparar as impressões auditivas de estudantes, professores e leigos para a voz, na docência do ensino fundamental. Métodos Estudo transversal formado por três grupos: 104 alunos; 40 professores e 40 não professores. O objeto de estudo foi um banco de 14 vozes, composto pela voz de uma atriz. Os participantes assinalaram as vozes preferidas para uma professora do ensino fundamental, indicando se eram agradáveis, motivadoras e capazes de despertar atenção. Resultados As vozes preferidas foram de qualidade vocal neutra (95,1%), pitch grave (75%) e velocidade lenta (67,9%), consideradas agradáveis, motivadoras e capazes de despertar atenção. As vozes menos escolhidas foram soprosa moderada (98,4%) e intensa (97,3%), rugosa leve (94,6%), moderada (94,0%) e intensa (94,6%), com articulação de fala imprecisa (94,0%), todas com psicodinâmica vocal negativa. A voz grave foi, proporcionalmente, a mais escolhida pelos professores (95%). As vozes de velocidade lenta, intensidade forte e soprosa leve foram mais assinaladas pelos leigos (90%, 52,5% e 37,5%) e os alunos indicaram menos as vozes rugosas leves e moderadas (1,9%). Conclusão Vozes de qualidade vocal neutra, de pitch grave e com velocidade de fala lenta são as preferidas para uma professora do ensino fundamental, consideradas agradáveis, motivadoras e capazes de despertar a atenção. Vozes com articulação de fala imprecisa, rugosas e soprosas moderadas e intensas não são bem aceitas e a psicodinâmica é negativa. Professores valorizam mais o pitch grave; leigos, a velocidade de fala lenta, soprosidade leve e intensidade forte e os alunos são os que mais avaliam negativamente as vozes rugosas.


ABSTRACT Purpose Compare the auditory perceptions of students, teachers and naive people regarding the voice, in elementary school teaching. Methods It is a cross-sectional study composed by three groups of 104 students, 40 teachers and 40 non-teachers. The object of the research was a 14-voice bank, composed by the voice of an actress. The participants pointed out which voices they would choose for an elementary school teacher, indicating if the voices were pleasant, motivating and able to arouse attention. Results The preferred voices were of neutral vocal quality (95.1%), bass pitch (75%) and slow speed (67.9%), considered pleasant, motivating and able to arouse attention. The less chosen voices were the moderate breathy (98.4%), intense breathy (97.3%), mild rough (94.6%), moderate rough (94.0%), intense rough (94.6%) and with imprecise speech articulation (94.0%), all of them with negative vocal psychodynamic. Proportionally, the bass voice was the most chosen by teachers (95%). The slow speed, strong intensity and mild breathy voices were more marked by naive people (90%, 52.5%, 37.5%) and the students reported less the mild rough (1.9%) and moderate rough (1.9%) ones. Conclusion Voices of neutral vocal quality, of bass pitch and with slow speech speed are the preferred ones for a teacher of elementary school, considered pleasant, motivating and able to arouse attention. The voices with imprecise speech articulation, moderate and intense rough and breathy are not well accepted and the psychodynamic is negative. Teachers appreciate more the bass pitch; naive people, the slow speech speed, mild breathy and strong intensity; and students evaluate negatively the rough voices.

RESUMO

Objetivo: Realizar uma revisão da literatura referente aos impactos da voz do professor no contexto da sala de aula Método: foi realizado levantamento na literatura publicada nos idiomas inglês, espanhol ou português, utilizando-se as bases de dados MEDLINE, IBECS, LILACS e Web of Science, dos últimos 15 anos. Foram utilizados os seguintes descritores e palavras-chaves: distúrbios da voz, disfonia, voz disfônica, qualidade da voz, testes de linguagem, compreensão, percepção da fala e cognição. Resultados: sete estudos foram selecionados de acordo com o tema de investigação em uma busca realizada nos últimos 15 anos. Foram encontrados sete estudos transversais e uma revisão de literatura, categorizados pelas autoras, da seguinte forma: disfonia e compreensão da linguagem; disfonia e compreensão da linguagem em ambiente ruidoso; percepção da voz disfônica; qualidade vocal e velocidade de fala. Conclusão: Os estudos evidenciam que a disfonia do professor interfere na compreensão da mensagem transmitida pelo professor para os alunos, principalmente em ambientes ruidosos. A voz disfônica do professor é avaliada negativamente pelos alunos e a velocidade de fala mais lenta se apresenta como um fator importante para o processamento da linguagem, no contexto da sala de aula.


Objective: To realize a review of the literature about the impact of teacher's dysphonia on student learning. Methods: It was conducted a survey over the last 15 years in national and international literature, published in English, Portuguese or Spanish, using the MEDLINE, IBECS, LILACS and Web of Science. The following keywords and descriptors were used: voice disorders, dysphonia, dysphonic voice, voice quality, language tests, comprehension, speech perception and cognition. Results: Eight articles have included the proposed criteria in the last 15 years. It was found seven cross-sectional studies and a literature review, which were categorized by the authors as follow: dysphonia and language comprehension, dysphonia and language comprehension in noisy environments; perception of dysphonic voice, vocal quality and speech rate. Conclusions: Studies show that teacher's dysphonia interferes in the understanding of the message in the classroom, especially in noisy environments. The students evaluate the dysphonic voice negatively. The speech rate also presented as an important factor for language processing.

RESUMO

OBJECTIVE: to assess the effectiveness of 2% papain gel compared to 2% carboxymethyl cellulose in the treatment of chronic venous ulcer patients. METHOD: randomized controlled clinical trial with 12-week follow-up. The sample consisted of 18 volunteers and 28 venous ulcers. In the trial group, 2% papain gel was used and, in the control group, 2% carboxymethyl cellulose gel. RESULTS: the trial group showed a significant reduction in the lesion area, especially between the fifth and twelfth week of treatment, with two healed ulcers and a considerable increase in the amount of epithelial tissue in the wound bed. CONCLUSION: 2% papain gel demonstrated greater effectiveness in the reduction of the lesion area, but was similar to 2% carboxymethyl cellulose gel regarding the reduction in the amount of exudate and devitalized tissue. Multicenter research is suggested to evidence the effectiveness of 2% papain gel in the healing of venous ulcers. UTN number: U1111-1157-2998.

RESUMO

O estudo teve como objetivos avaliar a efetividade do gel de papaína a 2% comparado ao gel de carboximetilcelulose a 2% no tratamento de pacientes com úlceras venosas crônicas e analisar as características sociodemográficas, econômicas e clínicas destes pacientes, atendidos no Ambulatório de Reparo de Feridas do Hospital Universitário Antonio Pedro/UFF. Método: Ensaio clínico controlado e randomizado (ECCR) com tempo de seguimento de 12 semanas. A amostra consecutiva foi composta por 18 voluntários e um total de 28 úlceras venosas. A coleta de dados ocorreu de abril de 2013 a janeiro de 2014. O desfecho primário do estudo foi a redução da área da lesão e os desfechos secundários foram a redução de tecidos desvitalizados no leito da úlcera e a redução da quantidade de exsudato. A pesquisa foi submetida ao Comitê de Ética em Pesquisa da Faculdade de Medicina, do Hospital Universitário Antonio Pedro/UFF e aprovada com o número 196/98, CAAE nº 0154.0.258.000-08. Resultados: Os grupos foram homogêneos quanto às características sociodemográficas, econômicas e clínicas. A idade dos voluntários variou de 45 a 85 anos, com média de 61,94 anos. A maioria dos participantes se declarou casado (55,6%), com escolaridade até o ensino fundamental (66,7%), residente de São Gonçalo (44,4%) e aposentado (66,7%). Todos os voluntários possuíam insuficiência venosa crônica, 61,1% apresentava hipertensão arterial sistêmica e 11,1% diabetes mellitus. A maioria das úlceras venosas lesões teve início há mais de dez anos (53,6%) e a localização mais acometida foi a região maleolar (53,6%). Quanto à evolução das úlceras ao longo de 12 semanas de tratamento, o grupo papaína apresentou redução significativa da área das lesões, especialmente no período entre a 5ª e a 12ª semanas de tratamento, com duas úlceras cicatrizadas e aumento expressivo da quantidade de tecido de epitelização no leito das lesões. Nos dois grupos de tratamento houve redução significativa da quantidade de tecido desvitalizado e aumento de tecido de granulação da 1ª semana para a 12ª semana (p-valor < 0,05). Conclusão: o gel de papaína a 2% apresentou maior efetividade quanto à redução da área das lesões, entretanto se mostrou similar ao gel de carboximetilcelulose a 2% quanto à redução da quantidade de exsudato e de tecido desvitalizado. A partir dos resultados da pesquisa foram destacados os principais cuidados de enfermagem que podem auxiliar a assistência e o tratamento de pacientes com úlceras venosas crônicas


The study aimed to evaluate the effectiveness of papain gel at 2% compared to the carboxymethylcellulose gel at 2% in the treatment of patients with chronic venous ulcers and analyze sociodemographic, economic and clinical characteristics of these patients, treated at the Outpatient Wound Repair at Antonio Pedro University Hospital/UFF. Method: Randomized Controlled Trial (RCT) with 12 weeks of follow-up. The consecutive sample consisted of 18 volunteers and a total of 28 venous ulcers. The data collection occurred from April 2013 to January 2014. The primary end point was the decrease of the lesion area and the secondary endpoints were devitalized tissue decrease in the ulcer bed and the reduction of the amount of exudate. The study was submitted to the Ethics Committee of the Faculty of Medicine, University Hospital Antonio Pedro/UFF and approved with the number 196/98, CAAE n. 0154.0.258.000-08. Results: The groups were homogenous regarding sociodemographic, economic and clinical characteristics. The volunteers ages ranged from 45 to 85 years old, with a mean of 61.94 years old. Most participants declared married (55.6%), with schooling up to elementary school (66.7%), resident of São Gonçalo (44.4%) and retired (66.7%). All volunteers had chronic venous insufficiency, 61.1% had hypertension and 11.1% diabetes mellitus. Most venous ulcers injuries began more than ten years ago (53.6%) and the most affected location was the malleolar area (53.6%). Regarding the ulcers evolution over the 12 weeks of treatment, the papain group showed a significant decrease in the lesions area, especially in the period between the 5th and the 12th weeks of treatment, with two healed ulcers and significant increase in the amount of epithelialization tissue. In both treatment groups, there was a significant decrease in the amount of devitalized tissue and an increase of the granulation tissue from 1st week to the 12th week (p <0.05). Conclusion: The papain gel at 2% was more effective in reducing of the lesions area, however it showed similar to the carboxymethylcellulose gel at 2% in reducing the amount of exudate and devitalized tissue. From the results of the research were highlighted the main nursing care that can help the assistance and treatment of patients with chronic venous ulcers

RESUMO

OBJETIVOS: compreender aspectos da trajetória profissional e continuidade acadêmica dada aos estudos pelos egressos de Fonoaudiologia. MÉTODO: foram convidados 250 egressos do curso de Fonoaudiologia/UFMG da instituição de origem (Primeira a décima turma), submetidos a um questionário de questões objetivas relativas à situação profissional, continuidade de estudos e formação acadêmica. Análise estatística: software Epi Info 6.04 (Testes Qui-quadrado e Exato de Fisher). RESULTADOS: a maioria dos egressos era do sexo feminino, média de idade de 25,7 anos (±1,7) e tempo de graduação entre 1,9 a quase 3 anos. A maior parte (55%) não tem na Fonoaudiologia a única fonte de renda; a jornada de trabalho semanal foi maior para quem vive exclusivamente do trabalho fonoaudiológico tendo realização profissional, mas não financeira. A maioria dos que não vivem da Fonoaudiologia não se sente nem financeiramente (97,2%) nem profissionalmente (69,4%) realizados (p<0,05). No grupo de egressos que vivem exclusivamente do trabalho, a avaliação sobre a formação acadêmica foi em sua maioria de muito boa a ótima. Dos que não vivem exclusivamente do trabalho, a formação mostrou-se igualmente dividida entre ruim e bom quanto em muito bom e ótimo (p= 0,03). 50% dos egressos relataram grande dificuldade para inserção no mercado de trabalho. CONCLUSÕES: o aumento da idade, maior tempo de graduação, jornada de trabalho acima de 20 horas, avaliação positiva sobre a formação acadêmica são aspectos que contribuíram para independência financeira do egresso fonoaudiólogo. Os alunos que relatam menores dificuldades na inserção do mercado de trabalho avaliaram o curso de graduação mais positivamente (muito bom /ótimo).


PURPOSE: to understand the aspects of the professional trajectory and continuity of academic studies by those who graduated on Speech, Language and Hearing Sciences (Ph). METHOD: it was invited 250 graduates from the course at UFMG, and they were submitted a questionnaire with questions regarding professional situation, their study's continuity and academic background. Estatistical analisis: Epi softaware Info 6.04. (Chi-square and Fisher's Exact Tests). RESULTS: most of the graduates were female, average age of 25,7 years old and time of graduation from 1,9 to almost 3 years. Most of them did not have in Ph the only source of income; the weekly working hours was higher for those who live exclusively of Ph work and they had professional achievement, but not financial. Most of those who do not have in Ph the source of income does not feel financially and professionally fulfilled (p<0,05). The evaluation of the academic background was mostly "very good to great" in the group of graduates who had Ph as exclusive source of income. Academic background was equally divided between "bad and good" as in "good and excellent" (p=0,03) in the group of graduates who does not have in Ph the only source of income. 50% of graduates reported great difficulty in entering in the labor market. CONCLUSIONS: the increased age, increased graduation time, working hours of over 20 hours, positive assessment of the academic background are aspects that contributed to the financial independence of the graduate in Ph. The students who reported fewer difficulties in entering in the labor market assessed the undergraduate program more positively.

RESUMO

Aim: to describe the main characteristics of Brazilian nursing and health groups registered in the Research Group Directory in Brazil involved in the study of wound care. Method: This is a documentary study which adopts a transversal approach, performed between March 3rd and April 10th 2012, with information collected from research groups that study wound care. Results: Of the 61 selected groups, 42.6% are located in the Southeast region of Brazil; only 44.26% of the groups have nursing staff involved. The majority of the group leaders are medical doctors; 78.7% of the groups have developed up to seven lines of research. Of these, 31.8% of the lines of research focus on histopathology and wound healing. Conclusion: Nursing staff develop many lines of research in the area of assistance and quality of life, but there is a significant paucity of research based on an interdisciplinary context.
