RESUMO
PURPOSE: Although the Braden Scale has been used as a basic tool to assess pressure ulcer risk, the validity of its effectiveness and accuracy was insufficient. Therefore, this study developed the groundwork for the predictive validity of the Braden Scale through a meta-analysis of prospective diagnosis assessment research. METHODS: Articles published between 1966 and 2013 from periodicals indexed in the Ovid Medline, Embase, CINAHL, KoreaMed, NDSL and other databases were selected, using the keyword 'pressure ulcer'. QUADAS-II was applied to assess the internal validity of the diagnostic studies. Selected studies were analyzed using meta-analysis with MetaDiSc 1.4. RESULTS: Twenty-one diagnostic studies with high methodological quality, involving 6070 patients, were included. The meta-analysis revealed that the pooled sensitivity was 0.72 (95% CI 0.68, 0.75); pooled specificity was 0.81 (95% CI 0.80, 0.82), and the sROC AUC was 0.84 (SE = 0.02). A detail analysis confirmed that age and reference standards were the factors that affected the diagnostic accuracy of the Braden Scale. CONCLUSION: The results suggest that the Braden Scale has a moderate predictive validity. This research also revealed the possibility that the predictive validity of the Braden Scale could be enhanced if it was applied differently according to the attributes of the study subjects.

OBJECTIVE: This study attempted to show evidence of exercise programs as intervention to decrease depressive symptoms and to improve quality of life and self-esteem in older people. DESIGN: Systematic review of randomized controlled trials. DATA SOURCES: Electronic databases of KoreaMed, Korea Scientific and Technological Intelligence Center, Korean Society of Nursing Science, Korean Academy of Psychiatric Mental Health Nursing, Ovid-Medline and Embase were searched up to May 25th, 2012 for relevant articles. REVIEW: We searched studies of randomized controlled trials involving exercise programs administered to participants aged 65 years or over. Of 461 publications identified, 18 met the inclusion criteria for the meta-analysis. Quality assessment of the studies utilized Cochrane's Risk of Bias. RESULTS: Exercise therapy in older people was effective, as evidenced by a decrease in depressive symptoms [standardized mean difference (SMD) -0.36; 95% confidence interval (CI) -0.64, -0.08], and improvements in quality of life (SMD 0.86; 95% CI 0.11, 1.62) and self-esteem (SMD 0.49; 95% CI 0.09, 0.88). The changes were significant statistically, with no heterogeneity. CONCLUSIONS: Exercise programs in older people are effective in improving depressive symptoms, quality of life and self-esteem. Development and efficient use of tailored exercise programs for elderly people is a prudent strategy.

PURPOSE: The aim of this study was to review the literature to determine whether intensive pelvic floor muscle training during pregnancy and after delivery could prevent urinary and fecal incontinence. METHODS: Randomized controlled trials (RCT) of low-risk obstetric populations who had done Kegel exercise during pregnancy and after delivery met the inclusion criteria. Articles published between 1966 and 2012 from periodicals indexed in Ovid Medline, Embase, Scopus, KoreaMed, NDSL and other databases were selected, using the following keywords: 'Kegel, pelvic floor exercise'. The Cochrane's Risk of Bias was applied to assess the internal validity of the RCT. Fourteen selected studies were analyzed by meta-analysis using RevMan 5.1. RESULTS: Fourteen RCTs with high methodological quality, involving 6,454 women were included. They indicated that Kegel exercise significantly reduced the development of urinary and fecal incontinence from pregnancy to postpartum. Also, there was low clinical heterogeneity. CONCLUSION: There is some evidence that for antenatal and postnatal women, Kegel exercise can prevent urinary and fecal incontinence. Therefore, a priority task is to develop standardized Kegel exercise programs for Korean pregnant and postpartum women and make efficient use of these programs.

PURPOSE: Infrared thermometers are increasingly used as a convenient, non-invasive assessment method for febrile children. However, the diagnostic accuracy of the infrared thermometer for children has been questioned, particularly in relation to sensitivity and specificity. The aim of this study was to evaluate diagnostic accuracy of infrared thermometers in febrile children. METHODS: Articles published between 1966 and 2012 from periodicals indexed in the Ovid Medline, Embase, CINAHL, Cochrane, KoreaMed, NDSL, KERIS and other databases were selected, using the following keywords: 'infrared thermometer'. The QUADAS-II was applied to assess the internal validity of the diagnostic studies. Selected studies were analyzed using meta-analysis with MetaDisc 1.4. RESULTS: Nineteen diagnostic studies with high methodological quality, involving 4,304 children, were included. The results of meta-analysis showed that the pooled sensitivity, specificity and AUC (Area Under the Curve) of infrared tympanic thermometers in children over 1 year were 0.80 (95% CI 0.78, 0.81), 0.94 (95% CI 0.93, 0.95) and 0.95 respectively. However the diagnostic accuracy of infrared tympanic thermometers in children with hyperthermia was low. CONCLUSION: The diagnostic accuracy of infrared tympanic thermometer was similar to axillary and rectal thermometers indicating a need for further research to substantiate these findings in children with hyperthermia.

PURPOSE: The purpose of this study was to determine whether upright position is effective in labor through systematic review in randomized controlled trials. METHODS: We established the PICO (Patient-Intervention-Comparator-Outcome) strategy, and reviewed 282 literatures from national and international electronic databases, and finally selected 9 references based on inclusion and exclusion criteria. We evaluated the quality of references and carried out a meta-analysis. RESULTS: The maternal outcomes showed that the duration of their second-stage labor was 2.29 minutes shorter than that of the women in the recumbent position, and were less likely to have episiotomy. The other outcomes, including the mode of delivery, blood loss, hemoglobin level, use of oxytocin, use of analgesics, and perineal laceration, did not differ between the groups. The fetal heart rate abnormality occurred less than in the control group. The Apgar scores of the groups did not differ. CONCLUSION: There is evidence that an upright position in the second stage of labor reduces the duration of the second stage of labor, the incidence of episiotomy, and an abnormal fetal heart rate.
