RESUMO

O estudo teve por objetivo averiguar como é a educação especial paraguaia e qual a visão da comunidade escolar de Salto Del Guairá ­ PY acerca da atuação de professores homens com crianças com deficiência. A pesquisa de campo foi realizada mediante gravação de entrevistas com uma Supervisora Pedagógica municipal, responsável por 17 instituições escolares de Salto Del Guairá, e uma mãe que reside no mesmo município e tem uma filha com deficiência, que estudou com um docente masculino em uma instituição inclusiva brasileira, em um município que faz fronteira com o Paraguai. Os resultados evidenciam que a Educação Especial paraguaia tem uma proposta que prevê o atendimento a pessoas com deficiência, mas na prática acaba não se concretizando, devido à falta de infraestrutura. A cultura paraguaia reproduz alguns padrões sociais de gênero e, desse modo, foi identificado um certo receio dos familiares quanto a atuação do docente masculino com crianças com deficiência.(AU)


The study aimed to find out what Paraguayan special education is like and what is the view of the school community of Salto Del Guairá - PY about the performance of male teachers with children with disabilities. The field research was carried out by recording interviews with a municipal Pedagogical Supervisor, responsible for 17 school institutions in Salto Del Guairá, and a mother who lives in the same municipality and has a disabled daughter, who studied with a male teacher at an institution inclusive, in a municipality bordering Paraguay. The results show that Paraguayan Special Education has a proposal that provides assistance to people with disabilities, but in practice it does not materialize, due to the lack of infrastructure. Paraguayan culture reproduces some social patterns of gender and, thus, a certain fear of family members was identified regarding the role of male teachers with children with disabilities.(AU)


El estudio tuvo como objetivo conocer cómo es la educación especial paraguaya y cuál es la visión de la comunidad escolar de Salto Del Guairá - PY sobre el desempeño de maestros varones con niños con discapacidad. La investigación de campo se llevó a cabo mediante la grabación de entrevistas con un Supervisor Pedagógico municipal, responsable de 17 instituciones escolares en Salto del Guairá, y una madre que vive en el mismo municipio y tiene una hija discapacitada, quien estudió con un maestro en una institución. inclusive, en un municipio fronterizo con Paraguay. Los resultados muestran que Educación Especial paraguaya tiene una propuesta que brinda asistencia a personas con discapacidad, pero en la práctica no se materializa, por falta de infraestructura. La cultura paraguaya reproduce algunos patrones sociales de género y, por lo tanto, se identificó cierto temor de los miembros de la familia con respecto al rol de los maestros con niños con discapacidad.(AU)

RESUMO

PURPOSE: Acute mesenteric ischemia (AMI) is a condition in pediatric surgery that ranges from intestine necrosis to death. Ischemic postconditioning (IPoC) methods were developed to reduce the damage caused by revascularization. This study aimed to evaluate the efficacy of these methods in an experimental weaning rat model. METHODS: Thirty-two 21-day-old Wistar rats were allocated into four groups according to the surgical procedure performed: control, ischemia-reperfusion injury (IRI), local (LIPoC) and remote IPoC (RIPoC). At euthanasia, fragments of the intestine, liver, lungs, and kidneys were submitted to histological, histomorphometric, and molecular analyses. RESULTS: In the duodenum, intestines, and kidneys histological alterations promoted by IRI were reversed by remote postconditioning method. In the distal ileum, the histomorphometric alterations could be reversed by the postconditioning methods with more evident effects promoted by the remote method. The molecular analysis found that the levels of expression of Bax (proapoptotic) and Bcl-XL (antiapoptotic) genes in the intestine were increased by IRI. These alterations were equally reversed by the postconditioning methods, with more evident effects of the remote method. CONCLUSIONS: IPoC methods positively reduced the damage caused by IRI in weaning rats.

RESUMO

BACKGROUND: Hirschsprung's Disease (HD) is characterized by intestinal sub-occlusion and the absence of enteric ganglion cells. A rectal biopsy examination is performed to confirm the diagnosis. In a recent study, we demonstrated that the analysis of 60 sections of rectal mucosa and submucosa stained by H&E may ensure a 90% diagnostic accuracy. Although the need to analyze so many sections makes the process of reading the slides more time-consuming, this encouraged us to study their distribution in the healthy rectal submucosa, to simplify the diagnosis. OBJECTIVES: To develop a method that facilitates HD diagnosis by studying the distribution of ganglion cells in the submucosal plexus. METHODS: Using the calretinin technique, we studied the distribution of plexuses in 60 fragments of rectal submucosa from 19 cadavers. After the study, the reading method created was used for diagnosis in 47 cases of suspected HD, using H&E staining. The accuracy was verified by comparing the results obtained with H&E to those obtained with the acetylcholinesterase technique, the golden standard in our laboratory. RESULTS: The study of submucosal plexus distribution showed that just by examining the submucosal region every 20 µm, approximately, it is possible to locate a ganglionic plexus, and we have already been able to diagnose HD with 93% accuracy. CONCLUSION: The study of ganglion cell distribution enabled the creation of a simplified method for reading the slides. The method applied achieved good accuracy and it can be used as an alternative method in HD diagnosis.

RESUMO

This study was conducted to describe the health conditions (the psychosocial aspects, sleep quality, and musculoskeletal symptoms) among Brazilian healthcare workers in the context of the pandemic. Workers answered an online questionnaire, including the short version of the Copenhagen Psychosocial Questionnaire (COPSOQ II), the Pittsburgh Sleep Quality Index (PSQI), the Nordic Musculoskeletal Questionnaire (NMQ), and the Beck Depression Inventory (BDI). The most unfavourable psychosocial factors were work pace (61%; 95% CI: 52-69%), emotional work demands (75%; 95% CI: 67-82%), predictability (47%; 95% CI: 39-56%), work-family conflict (55%; 95% CI: 46-64%), burnout (86%; 95% CI: 78-91%), and stress (81%; 95% CI: 73-87%). Most workers (74%; 95% CI: 66-81%) were classified as poor sleepers. Musculoskeletal symptoms were frequent in the neck (64%; 95% CI: 55-72%), shoulders (62%; 95% CI: 54-70%), upper back (58%; 95% CI: 50-67%), and lower back (61%; 95% CI: 52-69%). Depressive symptoms were also highly prevalent (mild: 22%; 95% CI: 15-30%, moderate: 16%; 95% CI: 11-23%, severe: 8%; 95% CI: 4-14%). Most healthcare workers experience unfavourable psychosocial factors, poor sleep quality, as well as musculoskeletal and depressive symptoms. These findings underscore the urgent need to acknowledge and address psychological and physical distress to improve the personal and professional well-being of this population.

RESUMO

PURPOSE: To evaluate the caliber of an arterial micro-anastomosis in the young growing animal using a continuous suture technique. Additionally, late morphological changes and blood flows distal to the anastomosis were evaluated. METHODS: Seventy-four Wistar rats were submitted to laparotomy to access the aorta for blood flow measurement. The aorta was sectioned using microsurgery technique and an end-to-end anastomosis with continuous suture. After a period of six months to one year, the anastomosis was checked. RESULTS: Regarding the size of the aortas, comparing the pre- and postoperative values, there was an increase of 13.33% in adult animals and 25% in young animals, without any difference in the blood flows. CONCLUSIONS: The arteries of young rats show signs of growth at the site of the anastomosis performed with continuous suture.

RESUMO

BACKGROUND: Incisional hernias are more frequent in adults than in children. It is hypothesized that a more efficient healing process in pediatric patients could explain this difference in incidence. Certain elements of healing such as neovascularization, degree of inflammation, percentage of mature and immature collagen, the proliferation of fibroblasts, and expression of certain genes could explain why healing in children is more efficient when compared to the adult and elderly populations. MATERIALS AND METHODS: Seventy-one rats of 3 different age groups (weaning, adult, and old) underwent surgery with 3 different incisions (vertical, oblique, and horizontal). During the procedure, the skin and abdominal wall of the animal were sectioned and only the skin was sutured to mimic incisional hernia in the animals. Four weeks after surgery, the rats were euthanized, their skin was removed, and the extent of scar tissue formed in the muscle opening was measured. In addition, samples of the scar tissue were collected for histological, immunohistochemical, and molecular analyzes. Nine rats served as controls. RESULTS: Shorter-length hernias were formed in weaning rats when compared to old ones when the surgical incision was horizontal (p = 0.03). There was a greater proliferation of fibroblasts in rats in the younger age groups, regardless of the type of incision. The Lox gene was more expressed in weaning rats with vertical and oblique incisions. CONCLUSIONS: These differences could explain the better healing and lower incidence of hernias in the pediatric population, although this aspect requires further studies.

RESUMO

ABSTRACT BACKGROUND AND OBJECTIVES: Psychosocial factors may be associated with multisite pain, which is characterized by pain symptoms in more than one part of the body. The aim of the present study was to determine associations between psychosocial factors and multisite pain in a population of workers. METHODS: A cross-sectional study was conducted involving 195 workers (educators, administrative technicians, healthcare workers, cleaners, and zookeepers). Psychosocial factors were evaluated using the short form of the second version of the Copenhagen Psychosocial Questionnaire. Multisite pain was identified using the Nordic Musculoskeletal Questionnaire. RESULTS: Multisite pain was associated with quantitative demands (OR=1.31; 95% CI: 1.06-1.63), work pace (OR=1.20; 95% CI: 1.01-1.43), emotional demands (OR=1.39; 95% CI: 1.18-1.63), commitment to the workplace (OR=0.75; 95% CI: 0.62-0.91), predictability (OR=0.86; 95% CI: 0.76-0.99), job satisfaction (OR=0.53; 95% CI: 0.32-0.88), work-family conflict (OR=1.37; 95% CI: 1.16-1.62), justice (OR=0.81; 95% CI: 0.69-0.94), general health perception (OR=0.54; 95% CI: 0.38-0.76), burnout (OR=1.41; 95% CI: 1.17-1.69), and stress (OR=1.41; 95% CI: 1.18-1.68). CONCLUSION: Several psychosocial factors were associated with multisite pain, indicating that these factors could be considered in the multisite pain management.

RESUMO

Objectives. This study aimed to identify the prevalence of musculoskeletal symptoms among blue-collar and white-collar workers stratified by gender and age. Methods. The sample was composed of 390 blue-collar and 510 white-collar workers. Musculoskeletal symptoms were evaluated using the Nordic musculoskeletal questionnaire. An independent t test or Mann-Whitney test was used for inter-group comparisons. The χ2 association test was applied for categorical variables. Logistic regression analysis was used to determine the influence of gender and age on musculoskeletal symptoms. Results. The prevalence of shoulder, lower back and ankle/foot symptoms was higher among blue-collar workers compared to white-collar workers. In the analysis stratified by gender, female blue-collar workers had a higher frequency of shoulder symptoms and male blue-collar workers had a higher frequency of lower back symptoms. In the analysis stratified by age, younger blue collar-workers had a higher frequency of shoulder, lower back and ankle/foot symptoms compared to young white-collar workers, and older white-collar workers had a higher frequency of neck symptoms compared to older blue-collar workers. Conclusions. Gender and age exerted an influence on self-reported symptoms in blue-collar and white-collar workers.

RESUMO

BACKGROUND: In pediatric liver transplantation, the optimal size of the transplanted liver ranges between 0.8% and 4.0% of the recipient's weight. Sometimes, the graft weight exceeds this upper limit, characterizing the large-for-size condition potentially associated with reduced blood flow and worsening of ischemia-reperfusion injury. Therefore, it would be beneficial to increase the portal flow through arterialization of the portal vein. Materials and methods: Fifteen pigs underwent large-for-size liver transplants. They were divided into two groups: control (CTRL 6 animals - conventional technique) and arterialization - a shunt was established between the portal vein and the splenic artery (ART 9 animals). Hemodynamic, biochemical, histological, and molecular variables were compared. Results: Arterialization resulted in a significant increase in portal vein pressure but no changes in other hemodynamic variables, as shown in the analysis of variance. It was observed lower ALT values (p = 0.007), with no differences regarding the values of blood pH and lactate (p = 0.54 and p = 0.699 respectively) or histological variables (edema, steatosis, inflammation, necrosis, and IRI - p = 1.0, p = 0.943, p = 0.174, p = 0.832, p = 0.662, respectively). The molecular studies showed significantly increased expression of IL6 after 3 hours of reperfusion (p = 0.048) and decreased expression of ICAM immediately after reperfusion (p = 0.03). The regression analysis suggested a positive influence of portal flow and pressure on biochemical parameters. Conclusion: Arterialization of the portal vein showed no histological, biochemical, or molecular benefits in large-for-size transplantation.

RESUMO

PURPOSE: To compare the adaptation processes of the remaining jejunum or ileum after extensive intestinal resection in a growing animal model. MATERIALS AND METHODS: Forty 21-day old rats were divided into four groups: JG: remaining jejunum group - ileal enterectomy; IG: ileum remaining group - jejunum enterectomy; SHAM: sham-operated group - open-and-close laparotomy; and NO: non-operated animals. RESULTS: After 3 weeks, JG and IG animals had decreased weights comparing to SHAM and NO animals (p = 0.017 and p = 0.005, respectively). The histomorphometric analysis showed that in JG animals the villi were higher than in SHAM, NO, and IG animals (p = 0.007, p = 0.008, and p = 0.01), the depth of crypts in JG and IG animals was greater than in NO and SHAM animals (p = 0.03, p = 0.002, and p = 0.003 respectively), and muscle layer thickness of the jejunum of JG animals had values greater than SHAM and NO animals (p = 0.01 and p = 0.02, respectively). The Ki-67 expression in the ileum was higher in comparison with the jejunum (p = 0.014). The pro-apoptotic gene (Bax) expression was decreased in JG animals compared to IG, SHAM, and NO animals (p = 0.013, p = 0.024, and p = 0.021). The anti-apoptotic gene (Bcl-XL) expression was decreased in JG animals in comparison to IG and NO animals (p = 0.002 and p = 0.046) although it was increased in the colon of IG animals in comparison to JG, SHAM, and NO animals (p = 0.002, p = 0.001, and p = 0.001, respectively). The Bax/Bcl-XL ratio was higher in JG than in IG animals (p = 0.011). CONCLUSION: Adaptive responses seemed to be more effective in the ileum than in the jejunum.

RESUMO

BACKGROUND: Ischemic preconditioning (IPC), either direct (DIPC) or remote (RIPC), is a procedure aimed at reducing the harmful effects of ischemia-reperfusion (I/R) injury. OBJECTIVES: To assess the local and systemic effects of DIPC, RIPC, and both combined, in the pig liver transplant model. MATERIALS AND METHODS: Twenty-four pigs underwent orthotopic liver transplantation and were divided into 4 groups: control, direct donor preconditioning, indirect preconditioning at the recipient, and direct donor with indirect recipient preconditioning. The recorded parameters were: donor and recipient weight, graft-to-recipient weight ratio (GRWR), surgery time, warm and cold ischemia time, and intraoperative hemodynamic values. Blood samples were collected before native liver removal (BL) and at 0 h, 1 h, 3 h, 6 h, 12 h, 18 h, and 24 h post-reperfusion for the biochemical tests: aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), creatinine, BUN (blood urea nitrogen), lactate, total and direct bilirubin. Histopathological examination of liver, gut, kidney, and lung fragments were performed, as well as molecular analyses for expression of the apoptosis-related BAX (pro-apoptotic) and Bcl-XL (anti-apoptotic) genes, eNOS (endothelial nitric oxide synthase) gene, and IL-6 gene related to inflammatory ischemia-reperfusion injury, using real-time polymerase chain reaction (RT-PCR). RESULTS: There were no differences between the groups regarding biochemical and histopathological parameters. We found a reduced ratio between the expression of the BAX gene and Bcl-XL in the livers of animals with IPC versus the control group. CONCLUSIONS: DIPC, RIPC or a combination of both, produce beneficial effects at the molecular level without biochemical or histological changes.

PURPOSE: To assess the biochemical, histological, histomorphometric and molecular effects of biliary duct ligation (BDL) induced liver cirrhosis in the heart and kidneys. METHODS: Thirty-two weaning rats (21 days old, 50-70 g) underwent BDL and were divided in four groups (euthanasia after two, four, six, and eight weeks, respectively) and compared to control groups. RESULTS: The animals' hearts of group 3 were bigger than those of the control group (p=0.042), including thinner right ventricle wall, decreased internal diameter of ventricles, and increased perivascular collagen deposition in left ventricle, as well as increased interstitial collagen in right ventricle after six weeks. In the kidneys of groups 3 and 4, bilirubin impregnation in the tubules, hydropic degeneration, loss of nuclei and lack of plasmatic membrane limits were noted. Nitric oxide synthase (NOS) gene expressions were higher in group 1 (p=0.008), and endothelial nitric oxide synthase (eNOS) gene expressions were elevated in all experimental groups (p=0.008, p=0.001, p=0.022, and p=0.013, respectively). In the heart, a decreased expression of eNOS in group 1 (p=0.04) was observed. CONCLUSIONS: Liver cirrhosis leads to histological and histomorphometric alterations in the heart and kidneys, with changes in the NOS and eNOS gene expressions, that may suggest a role in the associated myocardial and renal manifestations.

RESUMO

OBJECTIVES: Translate and culturally adapt the short version of Copenhagen Psychosocial Questionnaire II (COPSOQ II) into Brazilian Portuguese (COPSOQ II-Br) and evaluate its psychometric properties. METHODS: Translation and cultural adaptation followed the standardized guidelines. Structural validity was assessed using exploratory factorial analysis. Test-retest reliability was evaluated by intraclass correlation coefficient (ICC3,1) and internal consistency by Cronbach's alpha. Floor and ceiling effect was considered acceptable if less than 15% of participants reported the lowest or highest scores. Measurement error was assessed by standard error of measurement (SEM), while construct validity was tested by correlating the COPSOQ II-Br, the Job Content Questionnaire and the Nordic Musculoskeletal Questionnaire. RESULTS: The study evaluated a total of 211 civil servants and service providers in the test and 157 in the retest. After cross-cultural adaptation, the COPSOQ II-Br structure comprised seven domains and 11 dimensions. Most dimensions showed acceptable floor and ceiling effects, excepting "Work family conflicts" (floor effect of 26.1%), and "Meaning and commitment" and "Job satisfaction," with ceiling floor of 27.5% and 22.3%, respectively. Cronbach's alpha values reached the recommended levels (varied between 0.70 and 0.87). Test-retest reliability indicated that all dimensions had ICC between 0.71 and 0.81. SEM ranged from 0.6 to 2.2 and the construct validity showed good results with the tested instruments (significant positive and negative correlations). CONCLUSIONS: All psychometric properties of the short version COPSOQ II-Br are suitable for use in Brazil. The instrument is thus validated and can be used by occupational health and human resources professionals to evaluate psychosocial working conditions.
