MÉTODOS DE BIÓPSIA PULMONAR EMPREGADOS NO HOSPITAL UNIVERSITÁRIO DE SANTA MARIA: ACURÁCIA, SENSIBILIDADE E ESPECIFICIDADE

O objetivo desse estudo foi definir a acurácia diagnóstica, sensibilidade e especificidade dos dois principais métodos de biópsia pulmonar empregados no Hospital Universitário de Santa Maria (HUSM): biópsia endobrônquica e biópsia pulmonar percutânea transtorácica (BPPT) guiada por tomografia computadorizada. Foi delineado um estudo transversal em que se analisaram laudos anatomopatológicos das biópsias pulmonares realizadas no HUSM entre os anos de 2003 a 2013. Foram incluídos os laudos que possuíam pelo menos uma modalidade de biópsia pulmonar realizada, sendo precedente ao procedimento cirúrgico, o qual foi considerado como padrão-ouro. A acurácia da biópsia realizada por método endobrônquico, aferida através de curva ROC teve como área sob a curva o valor calculado de 0,645. Sua sensibilidade e especificidade foram, respectivamente, 43% e 85%. A acurácia da BPPT apresentou área sob a curva calculada em0,681. Sua sensibilidade foi 61% e sua especificidade 75%. Conclui-se que os resultados encontrados podem ser considerados razoáveis e ambos métodos podem ser utilizados na pratica clinica.Descritores: Biopsia; Lesão Pulmonar; Precisão da Medição Dimensional; Sensibilidade e Especificidade. 

HIV and Vertebral Fractures: a Systematic Review and Metanalysis.

The survival of HIV-infected patients has increased with the advent of antiretroviral therapy with the emergence of new comorbidities. Vertebral fracture is a manifestation of reduced bone strength and osteoporosis. This study aims to assess the frequency of spine fractures in HIV-positive men and women aged over 18 years. We performed a systematic review of randomized controlled trials, cohort studies, cross-sectional studies, and case-control studies. Studies that evaluated morphometric and/or clinical vertebral fracture were included. In total 488 studies were found, of which 53 had their full texts evaluated. A total of 85,411 HIV positive individuals were identified in 26 studies. The meta-analysis of the prevalence of vertebral fractures included 12 studies with 10,593 subjects. The prevalence was 11.1% [95% confidence interval (95% CI) 4.5%, 25.0%, I2 98.2% p < 0.00001]. When we evaluated independently studies of clinical vertebral fracture and morphometric vertebral fracture, the prevalence was 3.9% (95% CI 0.9, 15.8, I2 96.4% p < 0.00001) and 20.2% (95% CI 15.7%, 25.6%, I2 69.9% p = 0.003) respectively. HIV-infected individuals had an odds ratio of vertebral fractures of 2.3 (95% CI 1.37, 3.85, I2 98.2% p < 0.00001) when compared with HIV-uninfected patients (n = 9 studies). In conclusion, HIV-positive subjects had a higher risk of vertebral fractures when compared with HIV-negative subjects

Predictors of hip fracture mortality at a general hospital in South Brazil: an unacceptable surgical delay

OBJECTIVE: Hip fractures have been associated with increased mortality in the elderly. Several risk factors such as the time between the insult and the surgical repair have been associated with hip fracture mortality. Nevertheless, the risk of delayed surgical repair remains controversial. Few studies have examined this issue in Brazil. The aim of this study was to study the risk factors for death one year after hip fracture and in-hospital stay at a tertiary hospital in South Brazil. METHODS: A prospective cohort study was carried out from April 2005 to April 2011 at a tertiary university hospital at Santa Maria, Brazil. Subjects admitted for hip fracture who were 65 years of age or older were followed for one year. Information about fracture type, age, gender, clinical comorbidities, time to surgery, discharge, and American Society of Anesthesiologists score were recorded. Death was evaluated during the hospital stay and at one year. RESULTS: Four hundred and eighteen subjects were included in the final analysis. Of these, 4.3% died in-hospital and 15.3% were dead at one year. Time to surgery, American Society of Anesthesiologists score, Ischemic Heart Disease, and in-hospital stay were associated with death at one year in the univariate analysis. The American Society of Anesthesiologists score and time to surgery were one-year mortality predictors in the final regression model. In-hospital death was associated with American Society of Anesthesiologists score and age. CONCLUSION: Time to surgery is worryingly high at the South Brazil tertiary public health center studied here. Surgical delay is a risk factor that has the potential to be modified to improve mortality

VITAMIN D IS ASSOCIATED WITH A LOW QUALITY OF LIFE: A PRIMARY CARE STUDY

Introduction: Some studies have described impairment in quality of life of vitamin-deficient subjects. However, little is known about this association in primary care. This study aimed to evaluate the association between vitamin D deficiency and quality of life in postmenopausal women attending primary care in the municipality of Santa Maria - Brazil. Methods: A cross-sectional study was carried out with postmenopausal women over 55 years of age, accompanied in primary care, from March to August 2014. These women were randomly selected among the participants of a cohort study in the municipality of Santa Maria - Brazil. Data were collected through a standardized questionnaire, quality of life was assessed using the Short Form-36 Health Survey (SF-36), and 25-hydroxyvitamin D were measured using the ALPCO® ELISA method. Results: Of the total of 78 studied women, 11.54% had vitamin D deficiency. Women with vitamin D deficiency had a poorer quality of life assessed by SF-36. In the regression analysis, both vitamin D deficiency and falls were independently associated with a lower physical component of the SF-36. Conclusion:  Vitamin D deficiency is associated with poorer quality of life in the studied postmenopausal women
