FETAL LUNG MATURITY PREDICTION BY PLACENTAL GRADE AND BIPARIETAL DIAMETER

中华医学杂志(英文版) 1985年第8期98卷 561-564页

作者：邹玲 Harvey A gabert Willam J McGanity Department of Obstetrics and Gynecology Affiliated Hospital Shandong Medical College Jinan China

Fetal lung maturity was studied in 108 singleton pregnancies. Placental grades and biparietal diameter measurements were recorded. Of these. 58 also had amniocentesis for lecithin-sphingomyelin ratio, phosphatidylglycerol and foam test. Factors such as maternal age, race, parity, and fetal sex were also studied to see if they influenced the placental grading. Placental grading appeared to be more advanced among those with first gravida who subsequently gave birth to a male offspring. When the placental grade was Ⅰ, Ⅱ, or Ⅲ and the biparietal diameter ≥ 8.7 cm, fetal lungs were all biochemically mature and none of the neonates developed respiratory distress syndrome after delivery. Utilizing both placental grading and biparietal diameter, fetal lung maturity could be predicted accurately, making amniocentesis unnecessary.

Introduction: According to anterior spine fusion intervertebral disc spacers made of titanium or cobalt-chromium al-loys are of special interest. With regard to postoperative problems implant related artifacts can lead to a decreased MRI evaluation. The focus of this study was to compare the respective implant artifact artifact range dependend on different MRI sequences. To simplify artifact evaluation we introduced in this study a new developed 0-1-2 score. Material and Methods: We performed an MRI artifact evaluation of 2 different metallic intervertebral disc spacers (cobalt-chromium and titanium alloy). A carcass porcine spine was employed. Considering 12 defined spinal regions of interest we evaluated the respective implant artifact properties independent from the total artifact volume by using a new developed 0-1-2 score. The artifact range was documented for 15 different MRI-sequences. Results: For the titanium spacer as well as the cobalt-chromium-spacer an MRI evaluation of the implant/disc space situation could not be carried out. In contrast to the cobalt chromium spacer the titanium spacer allowed a good differentiation of the spinal canal opposite to the implant. Optimal MRI imaging results for both metallic intervertebral disc spacers could be achieved considering TSE sequences. Conclusion: A comparison of these two metallic spacers showed in all examined sequences clear advantages in favour of the titanium spacer. The best MRI representation of both tested implants by reducing implant related artifacts could be achieved with fast spin echo (TSE-) sequences. In spite of the use of TSE sequences a variability of susceptibility artifacts has to be included with regard to implant shape and material. With regard to the results of this study the easy use of a new developed artifact score represented a useful help to compare implant related MRI artifact properties independent from the actual implant related total artifact volume.

Score based assessment of implant-related post fusion MRI artifacts focused on different interbody disc spacers: An <i>in vitro</i>study

引用

Open Journal of Clinical Diagnostics 2012年第2期2卷 23-29页

Interbody disc spacers for anterior spine fusion are made of different materials, such as titanium alloys or carbon fiber reinforced polymers (CFRP). Implant-related susceptibility artifacts can decrease the quality of MRI scans. This cadaveric study aimed to demonstrate the extent that implant-related MRI artifacting affects the post fusion differentiation of the spinal canal (SC) and intervertebral disc space (IDS). In 6 cadaveric porcine spines, we evaluated the post-im- plantation MRI scans of a titanium and CFRP spacer that differed in shape and surface qualities. A spacer made of human cortical bone was used as a control. A defined evaluation unit was divided into regions of interest (ROI) to characterize the SC and IDS. Considering 15 different MRI sequences read independently by an interobserver-validated team of specialists artifact-affected image quality of the median MRI slice was rated on a modified score of 0-1-2-3. A maximum score of 15 points for the SC and 9 points for the IDS (100%) was possible. Turbo spin echo sequences produced the best scores for both spacers and the control. Only the control achieved a score of 100%. For the IDS the titanium and CFRP spacer maximally scored 0% and 74%, for the SC 80% and 99%, respectively. By using favored T1 TSE sequences the CFRP-spacer represented clear advantages in post fusion spinal imaging. Independent of artifact dimensions the used scoring system allowed us to create an implant-related ranking of MRI scan quality in reference to the bone control.

＜正＞SummaryA study was performed to investigate the effect of different levels of dietary fibre （DF） and dietary prolein on visceral organ size, digestibility, nitrogen balance and energy metabolism in rats. Thirty-six male Wistar rats, initial body weight about 76 g. were used in a factorial design consisting of three levels of dietary fibre （low, 81 g/kg DM;medium, 215 g/kg DM and high. 326 g/kg DM） and two levels of dietary prolein （low, 120 g/kg DM and high. 223 g/kg DM）. The added fibre source was soybean hulls. Danish fish meal was used as sole source of dietary protein. Measurements of gas-exchange were done on six rats （one group） and urine and faeces were collected individually. The weight of the digestive tract was larger （P＜0/05） in rats fed the high fibre diet than in those fed the low fibre diet. As the level of soybean fibre increased, the digestibility of nutrients and energy linearly decreased. The apparent biological value decreased with increasing DF when rats were fed the high protein diet whereas no significant difference was found with increasing DF in rats fed the low protein diet. Heat production as a percentage of metabolisable energy was higher in rats fed the low protein diet than in rats fed the high protein diet, but no significant difference was found among DF levels. The low heat production in rals fed high fibre diet is probably due to an improved utilization of metabolisable energy for fat deposition compared to protein deposition.

Impact of the Normalized Copy Number of <i>BCR-ABL</i>Transcript upon Diagnosis on Prognosis in CML Patients Treated with Imatinib-Mesylate

引用

Open Journal of Blood Diseases 2011年第2期1卷 12-14页

作者： Christophe Martinaud Aurélie Mayet Sophie Bousquet Nathalie Beaufils Jean gabert Sophie Raynaud Marie-Joelle Mozziconacci 不详

Quantification of the BCR-ABL transcript is recommended to follow-up CML patients treated by imatinib mesylate (IM). Results are expressed as a normalized copy number (NCN) of BCR-ABL. We studied a cohort of 98 CML patients under IM as a first treatment and monitored by RQ-PCR after 12, 18 and 24 months according to the European LeukemiaNet recommendations. Our results support the hypothesis of an independent correlation between BCR-ABL NCN at diagnosis and major molecular response at 18 and 24 months in an inverse relationship. We also highlighted the possibility to use the NCN at diagnosis as a warning at diagnosis, and may be useful to identify patients who could benefit of a more rigorous follow-up.

ULTRASONIC PLACENTAL GRADING IN HIGH RISK PREGNANCY

引用

1985年第9期

作者：邹玲 Harvey A gabert William J McGanity

264 high risk pregnancy patients were studied by B mode ultrasound for placental grading and biparietal diameter (BPD) measurement. The Lecithinsphingomyelin (L/S) ratio, phosphatidyl-glyceroi (PG) and foam test were performed with 81 cases as control. Repeat cesarean sections were performed in 44 patients who did not have amniocentesis and their operation timing was based only upon placental grading, biparietal measurement and clinical examination. No respiratory distress syndrome (RDS) occurred in this group after delivery. This study shows that when BPD of≥ 8.7 cm is combined with Ⅰ, Ⅱ, or Ⅲ placental grading neonatal Dubowitz scores correspond to 38 weeks; neonatal birth weight is greater than 2,500 g and there is no RDS. Combined BPD of≥8.5 cm with a Grade Ⅲ placenta preclude the necessity for amniocentesis to prove fetal lung maturity. Grade Ⅲ placenta is more common in postdatism, chronic hypertension and preeclampsia and less common in diabetics.
