Performance Evaluation of the GlucoDr Plus Glucometer
Background: Because strict glucose control is important for reducing the complications of diabetes, the self-monitoring of blood glucose is one of the fundamental treatment modalities. Many glucometers have been developed. In the present study, we evaluated a new glucometer: GlucoDr (TM) Plus (Allmedicus, Anyang, Gyeonggi-do, Republic of Korea). Methods: The evaluation was performed based on Clinical and Laboratory Standards Institute guidelines. Interferences by ascorbic acid, uric acid, maltose, and acetaminophen were examined, and the performance of the unit was compared to those of six other glucometers. The effects of hematocrit, of oxygen partial pressure (PaO(2)), and of multiple users were also evaluated. Results: Within-run, between-run, between- day, and total imprecision (coefficients of variation) were 0.99-4.98%. Satisfactory linearity was found for glucose concentrations of 32.5-786.5 mg/dL (R(2) = 0.9985). A comparison with the reference laboratory method showed close concordance over the entire range of concentrations evaluated (R(2) = 0.9869). No significant effects were noted due to added interferents, hematocrit, and PaO(2). Conclusions: The GlucoDr Plus showed acceptable performance in terms of precision and linearity. It was minimally affected by various interferents. GlucoDr Plus is suitable for the self-monitoring of blood glucose by patients with diabetes.Schleis TG, 2007, PHARMACOTHERAPY, V27, P1313Tsujimura S, 2006, BIOSCI BIOTECH BIOCH, V70, P654D`Orazio P, 2006, CLIN CHEM LAB MED, V44, P1486, DOI 10.1515/CCLM.2006.275Nathan DM, 2005, NEW ENGL J MED, V353, P2643Wild S, 2004, DIABETES CARE, V27, P1047*CLIN LAB STAND I, 2004, EP5A2 CLSI*CLIN LAB STAND I, 2003, EP6A CLSI*INT ORG STAND, 2003, 151972003E ISO*CLIN LAB STAND I, 2002, EP7A CLISTang ZP, 2001, CRIT CARE MED, V29, P1062Tang ZP, 2000, AM J CLIN PATHOL, V113, P75Turner RC, 1998, LANCET, V352, P837*CLIN LAB STAND I, 1995, EP9A CLSI1994, DIABETES CARE, V17, P81MERENSTEIN GB, 1993, PEDIATRICS, V92, P4741993, N ENGL J MED, V329, P977BARRETT AE, 1979, J CLIN PATHOL, V32, P893
Maternal Outcomes According to Placental Position in Placental Previa
<p><b>Purpose: </b>The purpose of this retrospective cohort study was to elucidate whether the location of placenta below uterine incision in cesarean section is important in the development of maternal complications in placenta previa patients.</p><p><b>Methods: </b>The study was conducted on 409 patients 414 parturition at 3 hospitals in affiliation with the Catholic Medical Center, Seoul, Korea from May 1999 to December 2009. The subjects were divided to two groups: the group whose placenta was located in the anterior portion of the uterus (anterior group) and the group whose placenta was located in the posterior portion of the uterus (posterior group). And then they are compared to each other. Logistic regression was used to control for confounding factors.</p><p><b>Results: </b>In the anterior group, regardless of confounding factors, the incidence of excessive blood loss (OR 2.97; 95% CI: 1.64-5.37), massive transfusion (OR 3.31; 95% CI: 1.33-8.26), placental accreta (OR 2.60, 95% CI: 1.40-4.83), and hysterectomy (OR 3.47, 95% CI: 1.39-8.68) was higher.</p><p><b>Conclusion: </b>Sonographic determination of the placental position where its location beneath the uterine incision is very important to predict maternal outcomes in placenta previa patients, and such cases, close attention should be paid for massive hemorrhage.</p
