Accuracy and reliability of weight change determinations in a model infant weighing less than 750 grams

We designed a study to address the accuracy and reliability of the weighing process for tiny infants ( < 750 gm). A model was made with intravenous bags and stockinette and the following equipment was added: umbilical artery and venous catheters, endotracheal tube, pulse oximeter probe, electrodes, and orgastric tube. The models weight was changed in intervals of 2 to 43 gm and it was then weighed on two different types of scales. The measured weight on each scale was compared with the predicted weight (calculated as initial + added mass), and the mean absolute difference (MAD) was determined. All measurements were obtained by the same two nurses. For the bedside scale the MAD was 5 gm (range - 23 to + 10; n = 30). Similar results were obtained with a sling scale; the MAD was 3 gm (range - 13 to + 6 n = 30). The range of differences noted suggests that discrepancies between measurements may lead to a difference between weights that is in the range of 4% to 7% body weight. Interobserver variability was noted to affect the reliability of the weight determinations. When five experienced neonatal intensive care units nurses weighed the model the MAD was 9 gm (-33 to + 22; n = 15) and 6 gm (range - 11 to + 28; n = 15) for the bedside and sling scales, respectively. For the predicted weight, these discrepancies represent potential errors of 7.4% and 5.2%, respectively. These values are likely to underestimate the potential errors seen clinically inasmuch as we could not duplicate infant movement or anxiety of the person weighing the infant. These results should be considered when protocols are developed for weighing extremely small preterm infants.

Nef harbors a major determinant of pathogenicity for an AIDS-like disease induced by HIV-1 in transgenic mice

The accuracy of antenatal weight data recorded in obstetric notes was investigated in the 45 hospital and community antenatal clinics within a South Thames Region NHS Trust. In order to assess the reliability and validity of all 60 clinic scales triplicate measurements of body weight for low- and high-weight subjects were recorded on each clinical scale and on a calibrated standard scale. The quality of weighing practice during antenatal care was investigated by means of semi-structured interviews conducted with all 33 midwives who currently provide antenatal care within the Trust. Beam balances had the highest reliability and validity, whereas scales with spring mechanisms were the least accurate. Only 40% of the clinics surveyed had access to beam balances, yet most of the maternal weight measurements recorded during antenatal care are likely to be out by no more than 1-1.5% of body weight. Weighing practice was generally inconsistent, and serial measurements of maternal body weight collected during pregnancy are probably too imprecise to provide a sensitive screen for conditions associated with unusual weight gain and too inaccurate to assess compliance with guidelines for weight gain.

摘要：采用EPMA、WDS和XRD对S32101双相不锈钢中厚板表面氧化铁皮显微结构进行研究，同时采用称重法测定出氧化增重曲线。结果表明：S32101双相不锈钢氧化铁皮厚度分布不均匀，氧化增重的平方值与氧化时间基本成直线关系。氧化铁皮外层物相为Fe2O3和Fe3O4，内层物相主要为FeCr2O4，局部区域存在MnCr2O4和NiCr2O4。结合热力学计算，得出了S32101双相不锈钢氧化铁皮形成的过程。
