question:
High tumor interstitial fluid pressure (IFP) is associated with poor outcome in locally advanced carcinoma of the uterine cervix. We have recently developed a noninvasive assay of the IFP of tumors, and in this assay, the outward interstitial fluid flow velocity at the tumor surface (v0) is measured by Gd-DTPA-based DCE-MRI and used as a parameter for IFP. Here, we investigated the independent prognostic significance of v0 in cervical cancer patients given cisplatin-based concurrent chemoradiotherapy with curative intent.', 'The study involved 62 evaluable patients from a cohort of 74 consecutive patients (Stage IB through IIIB) with a median follow-up of 5.5 years.', 'The actuarial disease-free survival (DFS) and overall survival (OS) at 5 years were 67% and 76%, respectively. Significant associations were found between v0 dichotomized about the median value and DFS and OS, both in the total patient cohort and a subcohort of 40 Stage IIB patients. Multivariate analysis involving stage, tumor volume, lymph node status, and v0 revealed that only v0 provided independent prognostic information about DFS and OS.
answer:
Does peritumoral interstitial fluid flow velocity predict survival in cervical carcinoma?


question:
n-3 Fatty acids lower plasma triacylglycerols not only in the fasting state but also in the postprandial state. However, it is not known whether chylomicrons, chylomicron remnants, and VLDLs are all affected equally or whether some lipoprotein species are lowered preferentially.', 'Lipoproteins, including large and small chylomicron remnants, were determined specifically with the aid of a newly developed method involving a combination of size-exclusion chromatography and fluorometric determination of retinyl palmitate, which served as a marker for exogenous fat.', 'Twelve hypertriacylglycerolemic men were treated for 6 wk with 4 capsules containing 85% fish-oil concentrate/d; each capsule contained 850 mg n-3 fatty acid ethyl esters (49.1% eicosapentaenoic acid by wt and 32.2% docosahexaenoic acid by wt). Oral-fat-tolerance tests were performed before and after the treatment. Blood samples were drawn in the fasting state and until 8 h postprandially.', 'Treatment with n-3 fatty acids reduced the fasting VLDL-triacylglycerol concentration by 44% (P < 0.05) and postprandial chylomicrons and VLDLs at 4, 6, and 8 h (P < 0.05) by 49-64% and 36-43%, respectively. Chylomicron remnants were reduced only in the late postprandial phase: large chylomicron remnants by 19% at 6 h and by 43% at 8 h (P < 0.05) and small chylomicron remnants by 31% at 8 h (P < 0.05).
answer:
Are postprandial chylomicrons and VLDLs in severe hypertriacylglycerolemia lowered more effectively than are chylomicron remnants after treatment with n-3 fatty acids?


question:
The present study was aimed at evaluating the outcome of pregnancies with nuchal cord.', 'A retrospective population-based study of all deliveries during the years 1988-2003 in a tertiary medical center was conducted. Immediate perinatal outcome of patients with and without nuchal cord was compared.', 'Of 166,318 deliveries during the study period, 14.7% had a nuchal cord, documented at birth (n=24,392). Higher rates of labor induction and non-reassuring fetal heart rate patterns were noted among pregnancies with nuchal cord as compared with the control group (30.1% vs. 24.2%; OR=1.3, 95% CI 1.3-1.4, P<0.001 and 4.5% vs. 2.6%; OR=1.8, 95% CI 1.6-1.9, P<0.001; respectively). The cesarean delivery rate was significantly lower among pregnancies with nuchal cord (11.5% vs. 12.7%; OR=0.9, 95% CI 0.8-0.9, P=0.001). Although 1 min Apgar scores lower than 7 were more common in pregnancies with nuchal cord (4.8% vs. 4.4%; OR=1.1, 95% CI 1.01-1.2, P=0.008), these pregnancies actually had lower rates of 5 min Apgar scores less than 7 (0.5% vs. 0.7%; OR=0.8, 95% CI 0.6-0.9, P=0.004). Likewise, the perinatal mortality rate was significantly lower in pregnancies with nuchal cord as compared with the comparison group (11/1,000 vs. 16/1,000; OR=0.7, 95% CI 0.6-0.8, P=0.001).
answer:

Is nuchal cord associated with adverse perinatal outcome?
