We also constituted an age- and sex-matched comparison group, consisting of randomly selected patients without any GP encounters for PNDs during the same period. Selected characteristics were then compared between PND patients and those in the comparison group over the 1-year study period. The study sample consisted of 275,685 PND patients and a similar number in the matched comparison group; mean age was 53.7 years, and 57% were women. PND patients were more likely than matched comparators to have encounters for various comorbidities, including circulatory system disorders (47% vs. 20%, respectively), depression (9% vs. 2%), and anxiety (4% vs. 1%) (all P < 0.01). They also were more likely to have received pain-related medications (57% vs. 13% for comparison group; P < 0.01),most commonly, nonsteroidal anti-inflammatory drugs, benzodiazepines, and opioids, and less often, tricyclic antidepressants and anti-epileptics. PND patients averaged 7.3 more GP visits during the year (mean [95% CI] = 9.9 [9.9, 9.9] vs. 2.6 [2.6, 2.7] for comparison group); they also had significantly more specialist referrals and physician-excused absences from work (all P < 0.01). Patients with PNDs under the care of GPs in Germany have comparatively more comorbidities and higher levels of use of healthcare services. The pain-related medications that these patients receive raise concerns that PNDs may not be optimally treated in these settings. [source] Head and neck squamous cell carcinoma cell lines: Established models and rationale for selectionHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 2 2007Charles J. Lin BA Abstract Background. Head and neck squamous cell carcinoma (HNSCC) cell lines are important preclinical models in the search for novel and targeted therapies to treat head and neck cancer. Unlike many other cancer types, a wide variety of primary and metastatic HNSCC cell lines are available. An easily accessible guide that organizes important characteristics of HNSCC cell lines would be valuable for the selection of appropriate HNSCC cell lines for in vitro or in vivo studies. Methods. A literature search was performed. Results. Cell growth and culture parameters from HNSCC cell lines were catalogued into tables or lists of selected characteristics. Methods for establishing cancer cell lines and basic cell culture maintenance techniques were reviewed. Conclusions. A compendium of HNSCC cell line characteristics is useful for organizing the accumulating information regarding cell line characteristics to assist investigators with the development of appropriate preclinical models. © 2006 Wiley Periodicals, Inc. Head Neck, 2006 [source] Influence of the length of the plasticating system on selected characteristics of an autothermal extrusion processADVANCES IN POLYMER TECHNOLOGY, Issue 1 2005Janusz W. Sikora Abstract The presented paper aims to determine the influence of the length of the plasticating system on the course of an autothermal extrusion process. Three special screws were used, of the relationship of the length of the operating part to diameter of the screw L/D = 20, 25, and 30, with a tip for intensive shearing and mixing, assigned for polyethylene processing, and five screw rotation frequencies were applied. The conducted research consisted of the measurement, during the extrusion, of the factors studied directly and in the calculation, and on their basis, the values characterizing this process. It is stated that the change of the length of the plasticating system in a significant way influences the dependences determining polymer flow rate, temperature and pressure of the processed polymer, extrusion velocity, specific energy consumption, and energy efficiency of the extruder; that is, the whole characteristic of an autothermal extrusion process. © 2005 Wiley Periodicals, Inc.

The purpose of this article is to describe processes and outcomes of utilizing active parent consent procedures with sixth-grade students from urban, ethnically diverse, economically disadvantaged K-8 public schools involved in an evaluation of a middle school service-learning program. METHODS: As part of the evaluation of the Lead Peace-Plus service-learning program, active parent consent was obtained for participation in school-based health surveys conducted with sixth graders in 3 schools. To achieve acceptable rates of parent permission, we employed multiple procedures including regular communication with school staff, incentives for involved schools and teachers, a multipronged approach for reaching parents, and direct encouragement of students to return forms through repeated classroom visits, individual and classroom incentives. We used Fisher's exact tests to compare selected characteristics among students whose parents weren't reached, those whose parents refused, and those whose parents consented to survey participation. RESULTS: We achieved a parent response rate of 94.6% among sixth-grade students. No significant differences in student gender, race/ethnicity, school, or free/reduced lunch status were identified across parent consent status groups. Rates of absenteeism were significantly higher (p = .03) among students whose parents weren't reached compared to other groups. CONCLUSIONS: Employing a multifaceted active parent consent campaign can result in high rates of parental response with limited sampling bias among an urban, ethnically diverse and economically disadvantaged group of middle school students. [source] SELECTED DEMOGRAPHIC, SOCIAL AND WORK CHARACTERISTICS OF THE AUSTRALIAN GENERAL MEDICAL PRACTITIONER WORKFORCE: COMPARING CAPITAL CITIES WITH REGIONAL AREASAUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 6 2000David Wilkinson ABSTRACT: The aim of the present study was to compare selected characteristics of the Australian general medical practitioner workforce in capital cities and regional areas. Data were derived from the 1996 Census of Population and Housing. Characteristics included age, sex, full- or part-time work, place of birth and change in residential address. Analyses were performed for each state and territory in Australia, the statistical division containing each capital city and all other statistical divisions in each state and territory. Of the 26 359 general medical practitioners identified, 68% were male. More female than male general medical practitioners were aged < 45 years (74 vs 52%, respectively; P < 0.0001). The proportion of general medical practitioners aged < 35 years was higher in capital cities (30%) than regional areas (24%; P < 0.0001). Overall, 32% of the general medical practitioner workforce was female and almost 50% of those aged < 35 years were female. The proportion of female general medical practitioners was higher in capital cities than regional areas, by up to 30%. While 13% of male general medical practitioners reported part-time work, 42% of females also reported part-time work and these figures were similar in capital cities and regional areas. Approximately 40% of the Australian general medical practitioner workforce was born outside Australia and while fewer migrants have entered in recent years they were more likely to be living in regional areas than the capitals. The census provides useful medical workforce data. The regional workforce tends to be made up of more males and is older than in capital cities. Monitoring trends in these characteristics could help to evaluate initiatives aimed at addressing regional workforce issues. [source] Serum bilirubin levels at 72 hours by selected characteristics in breastfed and formula-fed term infants delivered by cesarean sectionACTA PAEDIATRICA, Issue 7 2001SR Hintz The present multicenter study analysed the relative impact of maternal and infant factors on serum bilirubin levels at 72 ± 12 h in exclusively breastfed vs formula-fed term infants. End-tidal carbon monoxide levels corrected for ambient air (ETCOc), an index of bilirubin production, were measured in exclusively breastfed (B = 66) or formula-fed (F = 210) term infants at 2,8 h of age. Inclusion criteria included cesarean section to ensure a 3 d hospitalization, birthweight ±2500 g, gestational age ±37 wk and absence of any illness. The ETCOc for B infants and F infants did not differ significantly (1.3 ± 0.7 ppm vs 1.3 ± 0.8 ppm). The serum bilirubin level at 72 ± 12 h was significantly higher in B infants than in F infants (8.5 ± 3.4mg dl,1 vs 6.7 ± 3.4 mg d l,1, p < 0.001), as was the percentage weight loss from birthweight. Serum bilirubin levels were significantly higher in infants who were male, who did not have meconium-stained amniotic fluid, and in those whose mothers were insulin-dependent diabetics or hypertensive. There was no difference between groups in the need for phototherapy or exchange transfusion. Conclusion: Although higher bilirubin levels were observed in group B at 72 ± 12 h compared with group F, this finding was not of clinical or therapeutic consequence in this study. The lack of difference in ETCOc between the groups may be a factor of the timing of ETCOc measurement in this study, or may suggest that early increased bilirubin production is not a significant contributor to jaundice observed in exclusively breastfed infants.
