Could albumin level explain the higher mortality in hemodialysis patients with pulmonary hypertension?

Background: The pathogenesis of pulmonary hypertension (PH) in hemodialysis is still unclear. The aim of thisstudy was to identify the risk factors associated with the presence of PH in chronic hemodialysis patients and toverify whether these factors might explain the highest mortality among them.Methods: We conducted a retrospective study of hemodialysis patients who started treatment from August 2001to October 2007 and were followed up until April 2011 in a Brazilian referral medical school. According to theresults of echocardiography examination, patients were allocated in two groups: those with PH and those withoutPH. Clinical parameters, site and type of vascular access, bioimpedance, and laboratorial findings were comparedbetween the groups and a logistic regression model was elaborated. Actuarial survival curves were constructed andhazard risk to death was evaluated by Cox regression analysis.Results: PH > 35 mmHg was found in 23 (30.6%) of the 75 patients studied. The groups differed in extracellularwater, ventricular thickness, left atrium diameter, and ventricular filling. In a univariate analysis, extracellular waterwas associated with PH (relative risk = 1.194; 95% CI of 1.006 1.416; p = 0.042); nevertheless, in a multiple model,only left atrium enlargement was independently associated with PH (relative risk =1.172; 95% CI of 1.010 1.359;p = 0.036). PH (hazard risk = 3.008; 95% CI of 1.285 7.043; p = 0.011) and age (hazard risk of 1.034 per year of age;95% CI of 1.000 7.068; p = 0.047) were significantly associated with mortality in a multiple Cox regression analysis.However, when albumin was taken in account the only statistically significant association was between albuminlevel and mortality (hazard risk = 0.342 per g/dL; 95% CI of 0.119 0.984; p = 0.047) while the presence of PH lost itsstatistical significance (p = 0.184). Mortality was higher in patients with PH (47.8% vs 25%) who also had astatistically worse survival after the sixth year of follow up.Conclusions: PH in hemodialysis patients is associated with parameters of volume overload that sheds light on itspathophysiology. Mortality is higher in hemodialysis patients with PH and the low albumin level can explain thisassociation.© 2012 Greenfield et al.; licensee BioMed Central Ltd.

Grupo interdisciplinar: Construção de unidade educacional sistematizada em aprendizagem baseada em problemas

In 2003 the construction team of the 1st grade of the medical and nursing courses from a medical school began a work aiming at curriculum reconstruction, and restructured cognitive contents and the integration of basic and clinical aspects, in order to adapt to the incentive program for Curriculum Changes (PROMED) which allows for the continuity of curricular innovations. This team worked considering the group dynamics, a method already used in tutorial sessions which teachers have some familiarity with. For a good group performance the team participants were divided into two subgroups: one for constructing educational problems and the other for doing cognitive assessment exercises. The team and the subgroups met weekly, and every 15 days the group met for socialization of information, identifying the strengths and weaknesses of the process and/or products. A good adhesion, an active involvement of participants and satisfaction expressed by each participant with their inclusion in the group were reflected in the final product and contributed to the subjects' commitment to the proposal. This way, in the process the individual transformations and relations in a situation requiring the collaboration of professionals were essential in the process of permanent curricular reconstruction.

Frequency of multiple endocrine neoplasia type 1 in a group of patients with pituitary adenoma: genetic study and familial screening

The purpose of this study it was to evaluate the frequency of Multiple Endocrine Neoplasia type 1 (MEN1) in patients with pituitary adenoma and to perform genetic analysis and familial screening of those individuals afflicted with MEN1. 144 patients with pituitary adenoma at Botucatu Medical School, UNESP-Univ Estadual Paulista, were assessed retrospectively for MEN1 during the years of 2005-2011. The patients were evaluated for the presence of primary hyperparathyroidism (PHP) and enteropancreatic tumors. Genetic analysis was performed for the individuals with clinically diagnosed MEN1. Thirteen patients met the diagnostic criteria for MEN1, but three individuals belong to the same family and they were considered as a single MEN1 event, revealing 7.7 % frequency of MEN1 in this patient group. Genetic analysis showed MEN1 mutations in four index cases: IVS4+1 G>A, IVS3-6 C>T, c.1547insC and a new D180A mutation. One patient did not agree to participate in the genetic study and another one was referred for follow up in other hospital. Only polymorphisms were found in the other individuals, one of which was novel. We identified a high frequency of MEN1 in pituitary adenoma patients. Since PHP is one of the most common MEN1 tumor and patients are mostly asymptomatic, we suggest that all pituitary adenoma patients have their calcium profile analyzed. © 2013 Springer Science+Business Media New York.

Spirituality: Do teachers and students hold the same opinion?

Background:  Few studies have investigated potential differences between the opinions of educators and undergraduates regarding spirituality in patient care. Understanding these differences, could lead to better strategies for educational proposes. Purpose:  To compare the opinions of medical teachers (MTs) and medical students (MSs) regarding spirituality training in a Brazilian medical school. Methods:  A cross-sectional study was conducted. MTs and MSs filled out a questionnaire containing the Duke Religion Index, and questions regarding spirituality in clinical practice and at medical school. A comparison between early-curriculum MSs, late curriculum MSs and MTs was carried out. Chi-square (categorical) and Mann-Whitney (continuous/ordinal) tests were used. Results:  A total of 475 MSs and 44 MTs were evaluated. Results showed that MSs did not address spirituality as frequently as MTs (p<0.001), and that most participants did not feel prepared to address this issue, and believe that Brazilian medical schools are not giving all the required information in this field. Nevertheless, they believe MSs should be prepared to discuss these issues. Late-curriculum MSs believed that spirituality plays a more positive role in patient health (p=0.027), and were more prone to address this issue than early-curriculum MSs (p=0.023). Conclusion:  These findings revealed some of the challenges faced by spirituality medical training in Brazil, and differences between MTs and MSs regarding this issue. Further studies are needed to replicate these findings in other countries. © Blackwell Publishing Ltd 2013.

Ovarian Fibrothecoma in Mare - Case Report

A 5-year-old Mangalarga mare was referred to the Veterinary Teaching Hospital of the Veterinary Medical School in Botucatu with a complaint of a persistent 2-month ovarian follicle which had grown progressively to 20 cm in diameter. Ultrasonography showed a circular, cystic structure in the right ovary, whose wall was thickened and interior was filled with anechoic content. Ovarian neoplasia was suspected, and a unilateral ovariectomy was performed through the paralumbar fossa, using general anesthesia through inhalation. Histopathological evaluation concluded that the ovarian enlargement was caused by a fibrothecoma. The present report describes features of fibrothecoma, which is extremely rare in the equine species. © 2013 Elsevier Inc. All rights reserved.
