Time to an undetectable prostate‐specific antigen (PSA) after androgen suppression therapy for postoperative or postradiation PSA recurrence and prostate cancer‐specific mortality
Authors: D'Amico Anthony V. , McLeod David G. , Carroll Peter R. , Cullen Jennifer , Chen Ming‐Hui 
Published: February 2007

AbstractBACKGROUNDFor men receiving androgen‐suppression therapy (AST) for a rising postoperative or postradiation prostate‐specific antigen (PSA) recurrence, whether the time to an undetectable (u) PSA was significantly associated with prostate cancer‐specific mortality (PCSM) was evaluated.METHODSThe study cohort comprised 585 men with a rising PSA and negative bone scan after surgery (n = 415) or radiation therapy (n = 170) that were treated with AST and achieved a uPSA. Gray's regression was used to evaluate whether the time to a uPSA after AST was significantly associated with the time to PCSM after the uPSA adjusting for known prognostic factors.RESULTSThe median time (interquartile range) to achieve a uPSA was 4.6 (range, 2.8–7.8) months. There were 23 deaths, 4 of which were from prostate cancer. An increasing time to a uPSA (adjusted hazard ratio [HR]: 9.2, 95% confidence interval [CI]: 3.8, 22.1; P < .0001), a decreasing PSA doubling time (DT) (HR: 0.58, 95% CI: 0.43, 0.80; P = .0007), and Gleason score 8 to 10 cancers (HR: 8.6, 95% CI: 1.04, 77; P = .05) were significantly associated with a shorter time to PCSM.CONCLUSIONSDespite achieving a uPSA after AST, the risk of PCSM increased significantly as the time to the uPSA lengthens, especially in men with a short pre‐AST PSA DT and high‐grade prostate cancer. These men should be considered for randomized studies evaluating immediate vs delayed chemotherapy after the achievement of the uPSA. Cancer 2007. © 2007 American Cancer Society.
Primary urinary cytodiagnosis of a bladder small‐cell carcinoma
Authors: Rollins Susan , Schumann G. Berry 
Published: February 2007

AbstractA small‐cell undifferentiated tumor of the bladder in a 69‐yr‐old man with asymptomatic hematuria is described. Urine cytology showed abundant, small, round‐to‐oval hyperchromatic cells with coarse chromatin, nuclear molding, and high nuclear/cytoplasmic ratios. A primary cytodiagnosis of small‐cell undifferentiated cancer with associated severe urothelial atypia was made. Immunohistochemical stains were negative for neuron‐specific enolase, leukocyte common antigen, chromogranin, epithelial membrane antigen, prostatic acid phosphatase, and prostate‐specific phosphatase. The diagnosis was confirmed histologically by studies performed on cystoscopic bladder biopsy material.
Regenerative failure of diabetic nerves bridging transection injuries
Authors: Zochodne Douglas W. , Guo Gui Fang , Magnowski Brooks , Bangash Mohammed 
Published: February 2007

AbstractBackgroundFailed regeneration compounds the deficits imposed by diabetes from peripheral neuropathy. In this work, we addressed how diabetes or local glucose toxicity might impact peripheral nerve trunk regeneration and reconstitution across major sciatic nerve transection injuries of rats.MethodsSpecific conduits, amendable to manipulation of infused glucose concentrations through a T connection, were perfused with 5 or 30 mmol/L glucose in nondiabetics or 5 mmol/L glucose in rats with experimental diabetes. Quantitative early and later regenerative outgrowth was measured.ResultsLocal glucose exposure had no impact on early axon or Schwann cell outgrowth or partnering nor later myelinated axon regeneration. Despite only mildly attenuated early sprouting of axons with Schwann cells, diabetic bridges exhibited massive later failure of reconstitution by 3 weeks after injury.ConclusionDiabetes is associated with severe limitations in regenerative success, despite appropriate early axon outgrowth.

Published: February 2007

AbstractBackgroundIn patients with type 1 diabetes, three main variables need to be assessed to optimize meal‐related insulin boluses: pre‐meal blood glucose (BG), insulin to carbohydrate ratio (I : C), and basal insulin. We are presenting data for a novel use of the hyperinsulinaemic‐euglycaemic clamp (HEC) in patients with type 1 diabetes that minimizes the impact of these variables and can be used to determine the I : C.MethodsTen subjects (six men and four women) using continuous subcutaneous insulin infusion (CSII) pumps were recruited for this study [24–65 years; BMI 27.1 ± 4.9 kg/m2; A1C 7.2 ± 1.4% (mean ± SD)]. The HEC used a primed continuous intravenous insulin infusion of 40 mU/m2/min and a variable infusion of 20% glucose to maintain BG at 90 mg/dL. After subjects were in steady state (SS) for 50 min, a standardized meal (40% of total calories/day − 30% carbohydrate, 30% protein, 40% fat) was consumed. Subjects gave the insulin bolus with their CSII pump. No changes were made in the glucose infusion rate.ResultsMean BG at SS was 85.7 ± 10.4 mg/dL. Peak BG was 115.0 ± 12.7 mg/dL at 68.5 ± 8.8 min after the meal. Mean I : C was 1 : 9.3 ± 1.7 (range 1 : 7–1 : 12). Insulin sensitivity varied from 1.9 to 9.1 mg/kg/min.ConclusionsThe HEC can be used to reduce confounding factors and to determine the I : C. As a first estimate of the I : C in patients with type 1 diabetes, it is recommended to start with a ratio of 1 : 9.3 and to measure post‐prandial BG at 70 min.

Published: February 2007

AbstractBackgroundThe long‐range prediction from clinical variables of the onset of diabetes is important to patients and clinicians. Our objective was to evaluate the efficacy of various glucose‐related clinical measurements in predicting the 20‐year risk of developing type 2 diabetes (T2DM) in an elderly population.MethodsIn a prospective study, 672 men and women aged 59–92 years, who were not diabetic in 1980 and were part of a nationwide longitudinal randomized study, were followed‐up in 2000–2003. Fasting glucose, 1‐ and 2‐h post‐oral glucose tolerance and insulin were measured in 1980 and 2000–2003.ResultsA group of 174 (25.9%) survivors had progressed to diabetes during the 20‐year follow‐up. Fasting glucose values were a good predictor for diabetes. With the 100 mg/dL cut‐off of impaired fasting glucose (IFG), a 2–4‐times higher predictive sensitivity followed the dramatic increase in IFG prevalence compared to the 110 mg/dL cut‐off, but at a cost of reduced specificity and positive predictive value (PPV). By receiver operating curve (ROC) analysis, a 1‐h post‐load glucose was similar to 2 h and fasting glucose in prediction of the 20‐year incidence of diabetes, and classifying correctly the 77, 74 and 73% of the group, respectively. In adjusted logistic regressions, 2.28, 1.78 and 1.69‐folds increased the 20‐year risk, and were associated with each SD increment of the respective glucose values (p < 0.001).ConclusionsAlthough the best population‐based strategy for the diagnosis of T2DM would be the combination of fasting glucose followed by post‐load glucose, for the purposes of long‐term prediction of T2DM risk, fasting glucose is sufficient.

Learning with half a brain
Authors: Lent David D. , Pintér Marianna , Strausfeld Nicholas J. 
Published: February 2007

AbstractSince the 1970s, human subjects that have undergone corpus callosotomy have provided important insights into neural mechanisms of perception, memory, and cognition. The ability to test the function of each hemisphere independently of the other offers unique advantages for investigating systems that are thought to underlie cognition. However, such approaches have been limited to mammals. Here we describe comparable experiments on an insect brain to demonstrate learning‐associated changes within one brain hemisphere. After training one half of their bisected brains, cockroaches learn to extend the antenna supplying that brain hemisphere towards an illuminated diode after this has been paired with an odor stimulus. The antenna supplying the naïve hemisphere shows no response. Cockroaches retain this ability for up to 24 h, during which, shortly after training, the mushroom body of the trained hemisphere alone undergoes specific post‐translational alterations of microglomerular synaptic complexes in its calyces. © 2007 Wiley Periodicals, Inc.

Published: February 2007

AbstractTrifluoromethyl trifluoromethanesulfonate, CF3SO2OCF3, has been synthesised and its gas‐phase structure determined from electron‐diffraction data. This structural study was supported by HF, MP2 and DFT (B3LYP and B1B95) calculations, which revealed a strong dependence of the theoretical structure on the polarisation of the basis set. Infrared spectra for the gas and solid and a Raman spectrum for the liquid were obtained, and the observed bands were assigned. The experimental vibrational data, along with theoretical (B3LYP) force constants, were used to define a scaled quantum mechanical force field, which enabled reproduction of the measured frequencies with a final root‐mean‐square deviation of 6 cm–1.
