A new solid polymer electrolyte based on semi‐interpenetrating polymer networks (semi‐IPN) of crosslinked poly(glycidyl methacrylate‐co‐acrylonitrile)/poly(ethylene oxide) (P(GMA‐co‐AN)/PEO) was synthesized with diethylenetriamine (DETA) as the crosslinking agent and characterized. Fourier transform infrared spectroscopy (FTIR) spectra suggested the formation of semi‐IPN structure by crosslinking and revealed the interactions of Li+ ions with both the ether oxygen in PEO chain and the nitrogen atom in AN segments. Differential scanning calorimetry (DSC) and X‐ray diffraction pattern (XRD) measurements showed that crystallization of the semi‐IPN polymer electrolyte was greatly impeded. Measurement of mechanical properties revealed that tensile strength of the polymer electrolyte was increased after crosslinking. Results of electrochemistry tests suggested that the new polymer electrolyte exhibited a high‐ionic conductivity (10−4 S/cm) at room temperature, and an Arrhenius‐like behavior of the conductivity was observed. And the semi‐IPN polymer electrolyte with less content of PEO exhibited lower ion conductivity. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

The ThinPrep Imaging System (TIS) is an automated system that assists cytotechnologists in the primary screening of ThinPrep liquid based cervical samples. Between June 1, 2004, and April 1, 2005, four experienced cytotechnologists participated in the study in which the duration of the screening procedure was timed for each of the 11,354 slides included. In every slide 22 fields of view were reviewed, and the samples that contained potentially abnormal cells were fully screened. The screening time was reduced by 42% (mean) (p < 0.001). By manual rescreening of the negative TIS samples, abnormal cells were found in 10 samples (false negative rate 0.14%). In every case the abnormal cells had been identified by the scanner, but misinterpreted by the cytotechnologist. These findings stressed the importance of carefulness in the interpretation of the marked fields and beyond that helped the cytotechnologists and pathologists to have more confidence in the automated system.

Women with FIGO stage IA endometrial cancer have a very high disease-specific five year survival. Survival was related to histopathology. Follow-up at a highly specialized tertiary care center for patients with an extremely good prognosis may be questioned.

The results of the present study do not suggest a higher prevalence of endometrial cancer in women with polycystic ovary syndrome and/or clinical/biochemical hyperandrogenism than in the general population.

Little is known about age-dependent variation in outcomes of cervical cytology with modern technologies. This populationbased study evaluated age-dependent changes after routine implementation of ThinPrep and SurePath technology in two independent laboratories, and controlled for time trends in a third laboratory using manually read conventional cytology continually. Data were collected from the Danish National Health Care Registers. For each laboratory, we compared proportions of abnormal cytology defined as atypical squamous cells of undetermined significance or worse (ASCUS1) by age and technology phase. The study included 489,960 cytological samples with no recent abnormality from women aged 23-59 years, routinely screened between 1998 and 2007. Implementation of SurePath liquid-based cytology (LBC) was followed by an increase in abnormal cytology in women aged 23-29 years from 4.6 to 6.1%, relative proportion (RP): 1.31 [95% confidence interval (CI): 1.08-1.61], and a decrease in women aged 45-59 years from 2.9 to 2.0%, RP: 0.71 (95% CI: 0.60-0.83). Implementation of ThinPrep LBC was followed by a decrease in abnormal cytology both in women aged 23-29 years from 7.7 to 6.8%, RP: 0.89 (95% CI: 0.78-1.02) and in women aged 45-59 years from 3.4 to 1.0%, RP: 0.30 (95% CI: 0.24-0.37). With implementation of imaging-assisted reading, regardless of the brand of technology, the proportion of abnormality increased by around 30% in all age groups (range from 19 to 41%). In the laboratory with unchanged technology no trends in abnormality proportions were observed. The impact of LBC implementation on cytological abnormality proportions varied considerably across age groups.Liquid-based cytology (LBC) and automation-assisted reading of cytological samples have been widely implemented in cervical screening. Little attention has been given in the literature to how cytological abnormality proportions change by age, as a consequence of implementing new cytological technologies. [1][2][3] It is reasonable to test for a potential effect by age, given that infections with human papillomavirus (HPV) and cervical abnormalities are age-dependent.The impact of new cytological technologies on the overall abnormality proportions has been well studied.2,4-8 Important changes in screening efficiency can, though, go unnoticed when the data have not been stratified accordingly. Changes in the abnormality rates in screening are not without an impact on both the women and the health care system.A recent Danish observational study, 9 based on 390,000 cytological samples from the Department of Pathology,
