RESUMO

INTRODUCTION: Professional identity formation (PIF) is recognized worldwide as an outcome of medical education grounded in the psychology of adult development and the literature on medical professionalism. However, instruments to assess and support PIF are scarce. The Professional Identity Essay (PIE) is an open-ended question assessment of PIF that elicits short narrative responses from learners and that can be analyzed to provide formative feedback and an overall stage of development. In this study, our aim was to translate and adapt the PIE to Brazilian Portuguese. METHODS: We followed a systematic procedure for the translation and cross-cultural adaptation of the instrument. A pilot study was conducted with medical students from the University of São Paulo. After providing individual formative feedback, we administered an online questionnaire to the Brazilian students to better understand the consequences of using the PIE. Content analyses of qualitative data were performed, we employ manifest content analysis, and the categories of analysis emerged from the participants' speeches. RESULTS: Students found the instrument's questions easy to interpret and self-reflective. It also gave students the opportunity to consider their PIF. The PIE was perceived as reliable and brought more awareness of the students' own processes in addition to a sense of capability to foster their own development. In the same way, the students emphasized the importance of being helped in this process. CONCLUSION: We found sufficient evidence of the validity of the PIE in terms of content, face validity, and consequences of use. The PIE enhances self-assurance in PIF through formative assessment and is sensitive to different cultures, making it a potential tool for educators.

RESUMO

INTRODUCTION: Uncertainty tolerance (UT) is attracting increasing attention in medical education due to the numerous challenges associated with uncertainty in professional life. Inconsistencies in analysing the relationship between UT and moderators may arise from inadequate measurement methods. Most instruments were formulated before the most widely accepted framework was published. Our aim was to investigate the validity of an UT scale using an actual framework to corroborate with better and accurate instruments. METHODS: A total of 1052 students were invited. Various psychometric methods were used to explore validity of the TAMSAD scale in light of actual framework. Classic exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed. Secondly, content item classification was triangulated with exploratory graph analysis (EGA), and the new EFA, CFA, and cognitive diagnostic modelling (CDM) analysis were conducted. The reliability was calculated using Cronbach's alpha and McDonald's omega. RESULTS: A total of 694 students (65.9%) responded to the questionnaire. The reliability of the TAMSAD scale was 0.782. The initial EFA revealed no clear interpretable dimensions. The TAMSAD scale items can be classified into sources of uncertainty. The EGA has three dimensions, and the new EFA led to a 17-item TAMSAD scale with the following three dimensions: ambiguity, complexity, and probability. These dimensions lead to better adjustment fit indices in the new CFA and CDM analyses. CONCLUSION: We found evidence that the TAMSAD scale can be considered a multidimensional scale, organised in terms of sources of uncertainty.

RESUMO

BACKGROUND: Cleaning workers represent a significant proportion of the active population worldwide, with poor remuneration, particularly in developing countries. Despite this, they remain a relatively poorly studied occupational group. They are constantly exposed to agents that can cause symptoms and respiratory problems. This study aimed to evaluate upper airway inflammation in professional cleaning workers in three different occupational settings by comparing nasal cytology inflammation and clinical profiles. METHODS: We performed a cross-sectional study on the prevalence of upper airway inflammation and symptoms of asthma/rhinitis related to cleaning work, according to workplace. A total of 167 participants were divided into four groups: hospital, university, housekeeper and control. A nasal swab was collected for upper airway inflammation evaluation. Clinical profiles and respiratory symptom employee evaluations were performed using specific questionnaires (European Community Respiratory Health Survey-ECRS and the International Study of Asthma and Allergies in Childhood-ISAAC). RESULTS: Cleaning workers showed increased neutrophils and lymphocytes; the hospital and university groups showed increased macrophages compared to the housekeeper and control groups. The hospital and housekeeper groups showed increased eosinophils when they performed cleaning services for up to one year and reported having more asthma symptoms than the control group. Cleaning workers showed increased rhinitis symptoms. The university group showed increased rhinitis symptoms aggravated by the workplace compared with the hospital and housekeeper groups. Cleaning workers showed an increased affirmative response when directly asked about rhinitis symptoms compared to the control group. CONCLUSIONS: Cleaning workers showed airway inflammation, asthma symptoms and rhinitis, regardless of the occupational environment to which they were exposed, as well as showed increased rhinitis and asthma symptoms. Hospital cleaning workers showed increased macrophages, lymphocytes and eosinophils compared to the others. The length of time spent performing cleaning work was not related to nasal inflammation or respiratory symptoms in this population. However, there were differences in workplaces.

RESUMO

INTRODUCTION: Although the major alterations associated with asthma are related to the airways, there is also evidence of the importance of peribronchial vascular inflammation and remodeling in its pathophysiology. OBJECTIVES: To determine the effects of anti-IL-17 therapy on peribronchial vessels of an asthma model exacerbated by lipopolysaccharide. METHODS: We evaluated several factors, including lung function, inflammation, oxidative stress, vascular remodeling, and signaling pathways present in the peribronchial vessels of 66 male BALB/c mice exposed to ovalbumin and treated (or not) treated with anti-IL-17. Twenty-four hours before the end of the experimental protocol, groups of sensitized animals (OVA-LPS and OVA-LPS anti-IL-17) also received LPS. RESULTS: The OVA-LPS-anti-IL-17 group presented a decrease in several factors [airway resistance and elastance, bronchoalveolar lavage fluid (BALF) cell counts, inflammatory response, eosinophils, TSLP, IL-33, TARC, TNF-α, CD4+, CD8+, IL-4, IL-6, IL-10, IL-17, and VEGF positive cells/104µm2, peribronchovascular edema, and angiogenesis], including remodeling (MMP-9, MMP-12, TIMP-1 and TGF-ß positive cells and volume fraction of collagen fibers I, collagen fibers III, collagen fibers V, decorin, lumican, actin, biglycan, fibronectin, and integrin), oxidative stress (iNOS positive cells and volume fraction of PGF2α), and signaling pathways (FoxP3), as well as dendritic cells, NF-kB, ROCK-1, ROCK-2, STAT-1, and phosphor-STAT1-positive cells compared to OVA-LPS (p < 0.05). CONCLUSIONS: In this model of LPS-induced asthma exacerbation, IL-17 inhibition represents a promising therapeutic strategy, indicating the potential of bronchial vascular control of Th2 and Th17 responses and the activation of the remodeling and oxidative stress pathways, associated with the control of signaling pathways.

RESUMO

BACKGROUND: Asthma is a disease with reversible bronchoconstriction; however, some patients develop fixed airflow obstruction (FAO). Previous studies have reported the incidence and risk factors of FAO in adults; however, the corresponding factors in children remain poorly understood. AIM: To evaluate the incidence and risk factors of FAO in children and adolescents with asthma. METHOD: Observational and prospective cohort study with a 4-year follow-up of clinically stable patients with asthma (from 6-8 years old). Anthropometric data, history of asthma, number of hospitalizations, frequent exacerbations, asthma severity, asthma control, inhaled corticosteroid dose, atopy, and lung function were analyzed as potential risk factors for FAO. FAO was defined by a ratio of the forced expiratory volume in the first second to the forced vital capacity below the lower limit of normal, even after inhaled and oral corticosteroid treatment. RESULTS: Four hundred and twenty-eight patients were recruited, and 358 were analyzed. The FAO incidence in children and adolescents with asthma was 9.5% (n = 34), starting at 10 years of age. Age, body mass index, hospitalizations for asthma, bronchodilator response, frequent exacerbations, length of exacerbations, and asthma severity were associated with FAO. Frequent exacerbations (odds ratio [OR] = 4.0; 95% confidence interval [CI] = 1.3-11.7) and asthma severity categorized as steps 4 to 5 (OR = 3.5; 95% CI = 1.6-7.6) remained risk factors. CONCLUSIONS: Frequent exacerbations and asthma severity are the risk factors for FAO in children and adolescents with asthma.

RESUMO

Obese adults with asthma are more likely to develop dynamic hyperinflation (DH) and expiratory flow limitation (EFL) than nonobese asthmatics, and weight-loss seems to improve the breathing mechanics during exercise. However, studies evaluating the effect of weight loss on DH in obese adults with asthma have not been performed. We sought to evaluate the effect of a weight loss program on DH in obese adults with asthma. Forty-two asthma patients were enrolled in a weight loss program (diet, psychological support, and exercise) and were subsequently divided into two groups according to the percentage of weight loss: a ≥5% group ( n = 19) and a <5% group ( n = 23). Before and after the intervention, DH and EFL (constant load exercise), health-related quality of life (HRQoL), asthma control, quadriceps muscle strength and endurance, body composition, and lung function were assessed. Both groups exhibited a decrease of ≥10% in inspiratory capacity (DH) before intervention, and only the ≥5% group showed clinical improvement in DH compared with the <5% group postintervention (-9.1 ± 14.5% vs. -12.5 ± 13.5%, respectively). In addition, the ≥5% group displayed a significant delay in the onset of both DH and EFL and a clinically significant improvement in HRQoL and asthma control. Furthermore, a correlation was observed between reduced waist circumference and increased inspiratory capacity ( r = -0.45, P = 0.05) in the ≥5% group. In conclusion, a weight-loss of ≥5% of the body weight improves DH, which is associated with waist circumference in obese adults with asthma. In addition, the group with greater weight-loss showed a delayed onset of DH and EFL during exercise and improved asthma clinical control and HRQoL. NEW & NOTEWORTHY This is the first study to evaluate dynamic hyperinflation (DH) after a weight loss program in obese patients with asthma. Our results demonstrate that moderate weight loss can improve DH in obese patients with asthma that is associated with a decrease in abdominal fat. Moreover, a minimum of 5% in weight loss delays the onset of DH and expiratory flow limitation besides inducing a clinical improvement in asthma quality of life and clinical control.

RESUMO

BACKGROUND: The present study aimed to analyze the effects of physical training on an antioxidant canonical pathway and metalloproteinases activity in diaphragm muscle in a model of cigarette smoke-induced chronic obstructive pulmonary disease (COPD). METHODS: Male mice were randomized into control, smoke, exercise, and exercise + smoke groups, which were maintained in trial period of 24 weeks. Gene expression of kelch-like ECH-associated protein 1; nuclear factor erythroid-2 like 2; and heme-oxygenase1 by polymerase chain reaction was performed. Metalloproteinases 2 and 9 activities were analyzed by zymography. Exercise capacity was evaluated by treadmill exercise test before and after the protocol. RESULTS: Aerobic training inhibited diaphragm muscle wasting induced by cigarette smoke exposure. This inhibition was associated with improved aerobic capacity in those animals that were submitted to 24 weeks of aerobic training, when compared to the control and smoke groups, which were not submitted to training. The aerobic training also downregulated the increase of matrix metalloproteinases (MMP-2 and MMP-9) and upregulated antioxidant genes, such as nuclear factor erythroid-2 like 2 (NRF2) and heme-oxygenase1 (HMOX1), in exercise + smoke group compared to smoke group. CONCLUSIONS: Treadmill aerobic training protects diaphragm muscle wasting induced by cigarette smoke exposure involving upregulation of antioxidant genes and downregulation of matrix metalloproteinases.

RESUMO

BACKGROUND: The inverse relationship between exercise capacity and its variation over time and both cardiovascular and all-cause mortality suggests the existence of an etiological nexus between cardiometabolic diseases and the molecular regulators of exercise capacity. Coordinated adaptive responses elicited by physical training enhance exercise performance and metabolic efficiency and possibly mediate the health benefits of physical exercise. In contrast, impaired expression of genes involved in mitochondrial biogenesis or protein turnover in skeletal muscle-key biological processes involved in adaptation to physical training-leads to insulin resistance and obesity. Ingestion of fructose has been shown to suppress the exercise-induced GLUT4 response in rat skeletal muscle. To evaluate in greater detail how fructose ingestion might blunt the benefits of physical training, we investigated the effects of fructose ingestion on exercise induction of genes that participate in regulation of mitochondrial biogenesis and protein turnover in rat's skeletal muscle. METHODS: Eight-week-old Wistar rats were randomly assigned to sedentary (C), exercise (treadmill running)-only (E), fructose-only (F), and fructose + exercise (FE) groups and treated accordingly for 8 weeks. Blood and quadriceps femoris were collected for biochemistry, serum insulin, and gene expression analysis. Expression of genes involved in regulation of mitochondrial biogenesis and autophagy, GLUT4, and ubiquitin E3 ligases MuRF-1, and MAFbx/Atrogin-1 were assayed with quantitative real-time polymerase chain reaction. RESULTS: Aerobic training improved exercise capacity in both E and FE groups. A main effect of fructose ingestion on body weight and fasting serum triglyceride concentration was detected. Fructose ingestion impaired the expression of PGC-1α, FNDC5, NR4A3, GLUT4, Atg9, Lamp2, Ctsl, Murf-1, and MAFBx/Atrogin-1 in skeletal muscle of both sedentary and exercised animals while expression of Errα and Pparδ was impaired only in exercised rats. CONCLUSIONS: Our results show that fructose ingestion impairs the expression of genes involved in biological processes relevant to exercise-induced remodeling of skeletal muscle. This might provide novel insight on how a dietary factor contributes to the genesis of disorders of glucose metabolism.

RESUMO

BACKGROUND AND PURPOSE: Asthma is a disease of high prevalence and morbidity that generates high costs in hospitalization and treatment. Although the airway is involved in the physiopathology of asthma, there is also evidence of the importance of vascular and lung parenchyma inflammation and remodeling, which can contribute to the functional pulmonary alterations observed in asthmatic patients. Our aim was to evaluate treatment using sakuranetin, a flavone isolated from the twigs of Baccharis retusa (Asteraceae), on vascular and lung parenchyma alterations in an experimental murine model of asthma. METHODS: Male BALB/c mice were subjected to a sensitization protocol with ovalbumin for 30days and were treated with or without sakuranetin (20mg/kg/mice) or dexamethasone (5mg/kg/mice); then, the lungs were collected for histopathological analysis. We evaluated extracellular matrix remodeling (collagen and elastic fibers), inflammation (eosinophils and NF-kB) and oxidative stress (8-isoprostane) in the pulmonary vessels and lung parenchyma. The thickness of the vascular wall was quantified, as well as the vascular endothelial growth factor (VEGF) levels. RESULTS: We demonstrated that sakuranetin reduced the number of eosinophils and elastic fibers in both the pulmonary vessels and the lung parenchyma, probably due to a reduction of oxidative stress and of the transcription factor NF-kB and VEGF levels in the lung. In addition, it reduced the thickness of the pulmonary vascular wall. The treatment had no effect on the collagen fibers. In most of the parameters, the effect of sakuranetin was similar to the dexamethasone effect. CONCLUSIONS AND IMPLICATIONS: Sakuranetin had anti-inflammatory and antioxidant effects, preventing vascular and distal parenchyma changes in this experimental model of asthma.

RESUMO

OBJECTIVES: Cognitive impairment in the elderly is frequently overlooked by general practitioners. The use of subjective memory complaints as a sign of cognitive impairment by the general practice is controversial. METHODS: Elderly individuals (N = 248) were asked whether they had memory complaints and underwent a cognitive impairment screening. Subjects classified as exhibiting "probable cognitive impairment" underwent a complete cognitive evaluation, and the final diagnoses were established by expert consensus. RESULTS: A total of 147 patients presented with subjective memory complaints, and 43 were further classified as demented or "cognitively impaired not demented". Subjective memory complaints presented a sensitivity of 100% and a negative predictive value of 100%. CONCLUSION: Subjective memory complaints are an indicator for cognitive impairment screening.

RESUMO

OBJECTIVE: Pulmonary embolism is an underdiagnosed major cause of death for hospitalized patients. The objective of this study was to identify the conditions associated with fatal pulmonary embolism in this population. METHODS: A total of 13,074 autopsy records were evaluated in a case-control study. Patients were matched by age, sex, and year of death, and factors potentially associated with fatal pulmonary embolism were analyzed using univariate and multivariate conditional logistic regression. RESULTS: Pulmonary embolism was considered fatal in 328 (2.5%) patients. In the multivariate analysis, conditions that were more common in patients who died of pulmonary embolism were atherosclerosis, congestive heart failure, and neurological surgery. Some conditions were negatively associated with fatal pulmonary embolism, including hemorrhagic stroke, aortic aneurism, cirrhosis, acquired immune deficiency syndrome, and pneumonia. In the control group, patients with hemorrhagic stroke and aortic aneurism had short hospital stays (8.5 and 8.8 days, respectively), and the hemorrhage itself was the main cause of death in most of them (90.6% and 68.4%, respectively), which may have prevented the development of pulmonary embolism. Cirrhotic patients in the control group also had short hospital stays (7 days), and 50% died from bleeding complications. CONCLUSIONS: In this large autopsy study, atherosclerosis, congestive heart failure, and neurological surgery were diagnoses associated with fatal pulmonary embolism.

RESUMO

The objective of this study was to compare the impact on knowledge and counseling skills of face-to-face and Internet-based oral health training programs on medical students. Participants consisted of 148 (82 percent) of the 180 invited students attending their fifth academic year at the Faculty of Medicine, University of São Paulo, Brasil, in 2007. The interventions took place during a three-month training period in the clinical Center for Health Promotion, which comprised part of a clerkship in Internal Medicine. The students were divided into four groups: 1) Control Group (Control), with basic intervention; 2) Brochure Group (Br), with basic intervention plus complete brochure with oral health themes; 3) Cybertutor Group (Cy), with basic intervention plus access to an Internet-based training program about oral health themes; and 4) Cybertutor + Contact Group (Cy+C), the same as Cy plus brief proactive contact with a tutor. The impact of these interventions on student knowledge was measured with pre- and post assessments, and student skills in asking and counseling about oral health were assessed with an objective structured clinical examination (OSCE). Multivariate logistic regression models were applied to identify the odds ratios of scoring above Control's medians on the final assessment and the OSCE. In the results, Cy+C performed significantly better than Control on both the final assessment (OR 9.4; 95% CI 2.7-32.8) and the OSCE (OR 5.6; 95% CI 1.9-16.3) and outperformed all the other groups. The Cy+C group showed the most significant increase in knowledge and the best skills in asking and counseling about oral health.

RESUMO

Introducción: El tabaquismo constituye un grave problema de salud pública en todo el mundo. Los modelos animales actúan como un paso intermedio entre los estudios de laboratorio y los estudios en seres humanos. Los modelos aplicados son difíciles de reproducir debido al uso de diferentes tipos de cámaras inhaladoras y principalmente por la falta de una monitorización constante de la concentración del humo del tabaco.ObjetivoDesarrollar una cámara inhaladora para ratas (con la exposición exclusiva del hocico) en la que pueda mantenerse y monitorizarse constantemente la cantidad de monóxido de carbono (CO).Material y métodosSe expusieron ratas Wistar macho, de 250g de peso, a 50 partes por millón de CO producido por el humo del tabaco de un cigarrillo sin filtro. Los animales se sometieron a una exposición de 2h y, acto seguido, fueron sacrificados a las 0, a las 4, a las 24 y a las 48h. El grupo de control se dejó libre dentro de pequeñas cámaras perpendiculares y solo recibió 5l/min de aire comprimido.ResultadosEl modelo fue capaz de aumentar la concentración de carboxihemoglobina inmediatamente después del término de la exposición (p<0,001), observándose una disminución desde las 2h en adelante comparado con la concentración del grupo de control. La concentración plasmática de cotinina aumentó inmediatamente después de la exposición y todavía se detectó a las 2 y a las 4h (p<0,05).ConclusiónConcluimos que este sistema de cámara inhaladora puede mantener una concentración controlada de CO en un modelo en el que se expone a pequeños animales a la inhalación de humo de cigarrillos, lo que permite estudios adecuadamente controlados, al igual que investigaciones sobre otros gases tóxicos y contaminantes ambientales(AU)


Introduction: Smoking is a serious worldwide public health problem. Animal models act as a bridge between laboratory and human studies. The models applied are difficult to reproduce because of the use of different types of inhalation chambers and mainly because of the lack of continuous monitoring of smoke concentration.ObjectiveTo develop an inhalation chamber for rats (with only the nose exposed) in which the amount of carbon monoxide (CO) can be maintained and monitored constantly.Material and methodsMale Wistar rats weighing 250g were exposed to 50ppm CO produced by the smoke from a filter-free cigarette. The animals were submitted to a single 2-h exposure and then sacrificed at 0, 4, 24 and 48h. The control group was left restrained inside the small perpendicular chambers, receiving only 5L/min of compressed air.ResultsThe model was able to increase HbCO levels immediately after the end of exposure (p<0.001), with a decrease being observed from 2h onwards when compared to the levels of the control group. Plasma cotinine increased immediately after exposure, and showed still detectable levels at 2 and 4h (p<0.05).ConclusionWe conclude that the presented inhalation chamber system is able to maintain a controlled CO concentration in a model in which small animals are exposed to the inhalation of cigarette smoke, permitting well-controlled studies, as well as investigations involving other toxic gases and air pollutants(AU)

RESUMO

BACKGROUND: Studies investigating the performance of instruments to detect major depressive disorder (MDD) have reported inconsistent results. Subsyndromal depression (SD) has also been associated to increased morbidity, and little is known about its detection in primary care setting. This study aimed to investigate the performance of the Primary Care Evaluation of Mental Disorders (PRIME-MD) to detect MDD and any depression (threshold at SD) in an outpatient unit of a teaching general hospital. METHODS: Nineteen primary care physicians using the PRIME-MD evaluated 577 patients, 240 of them (75% female; mean age, 40.0 +/- 14.4), including all with MDD and a randomly subset of those without MDD, were evaluated by 11 psychiatrists using the Structured Clinical Interview Axis I Disorders, Patient Version (SCIDI/P) for DSM-IV as the standard instrument. RESULTS: The kappa between the PRIME-MD and the SCID was 0.42 for the diagnosis of any depression and 0.32 for MDD. The distribution of the number of depressive symptoms per patient suggested the existence of a continuum between SD and MDD, and a high frequency of subjects with 4-6 symptoms (close to the cutoff for the diagnosis of MDD). LIMITATIONS: The sample has a modest size and is a subset of an original one. CONCLUSION: A continuum between SD and MDD may in part explain the relatively low agreement for the diagnosis of MDD in our sample and possibly in other studies. Studies investigating the performance of screening instruments to detect MDD, should consider the relevance of identifying SD, and the influence of the distribution of the number of depressive symptoms in their results.

RESUMO

CONTEXT: First year medical students experienced early patient contact by observing outpatient consultations. OBJECTIVES: To evaluate a questionnaire designed to examine emerging attitudes during the development of a doctor-patient relationship. METHODS: First year medical students participated in medical outpatient consultations as observers. These consultations represented a total of 295 registered clinical appointments. After each observation, the students completed a questionnaire surveying themes related to the doctor-patient encounter. An instructor met the students at the end of the appointments to discuss the questions raised. The Dundee Ready Education Environment Measure was used to assess the course environment. RESULTS: Students found the activity useful and enjoyable. They reported increased self-esteem and enhanced enthusiasm for the study of medicine. They completed write-ups describing and evaluating the questionnaire data. The questionnaire notes showed homogeneity among the students. The Dundee Measure indicated the students regarded the learning environment positively (62.2%); social and ambient conditions were rated highly (64.6% and 64.7%, respectively). CONCLUSION: The teaching of humanitarian attitudes by observation of the doctor-patient relationship in practice was welcomed by students. The environment in which this educational programme was carried out was considered adequate. The outpatient service schedule and the limited time available for student instruction on the part of staff doctors made this activity productive. The programme motivated students towards higher achievement and the pursuit of medical responsibility as well as more developed humanitarian behaviour patterns.
