CHAMP high-quality vector magnetometer observations collected from July 2000 to September 2010 have been used to map the residual vector magnetic anomaly fields. This field is so called the lithospheric magnetic field which is the result of two contributions of the induced a.d.the remanent magnetization. It is therefore essential to study the magnetic properties of the crustal rocks. Isolating this field from the other contributions, interpreting a.d.even defining are however difficult a.d.still debated. We investigate how to identify a.d.separate the lithospheric vector magnetic field ΔX, ΔY a.d.ΔZ from other contributions. For this purpose we use selected night magnetic data from which we remove a model field of degree 16 a.d.external model field of degree 2 developed by spherical harmonics analysis. Concerning the induced lithospheric field which is assumed to be aligned with the internal dipole was also removed. To minimize the secular variation effects, we calculated internal models for each two months. The method developed here has been successfully applied to isolate lithospheric field produced by remanent magnetizations from CHAMP satellite data. The resolution a.d.altitude measurements make it very ha.d.to map short wavelength crustal magnetic anomalies. The large-scale strong magnetic anomalies detected using this technique are in agreement with previous global magnetic maps. These anomalies appear with an amplitude of about 10 nT at satellite altitude such as Bangui’s anomaly.

AIM: To assess the safety a.d.efficacy of trans-arterial chemo-embolization (TACE) in very elderly patients. METHOdS: A prospective cohort study, from 2001 to 2010, compared clinical outcomes following TACE between patients ≥ 75 years old a.d.younger patients (aged between 65 a.d.75 years a.d.younger than 65 years) with hepatocellular carcinoma (HCC), diagnosed according to the European Association for the Study of the Liver a.d.the American Association for the Study of Liver diseases criteria. The decision that patients were not ca.d.dates for curative therapy was made by a multidisciplinary HCC team. data collected included demographics, co-morbidities, liver disease etiology, liver disease severity a.d.the number of procedures. The primary outcome was mortality; secondary outcomes included post-embolization syndrome (nausea, fever, a.d.minal right upper quadrant pain, increase in liver enzymes with no evidence of sepsis a.d.with a clinical course limited to 3-4 d post procedure) a.d.30-d complications. a.d.tionally, changes in liver enzyme measurements were assessed [alanine a.d.aspartate aminotransferase (ALT a.d.AST), gamma-glutamyl transpeptidase a.d.alkaline phosphatase] in the week following TACE. Analysis employed both univariate a.d.multivariate methods (Cox regression models). RESULTS: Of 102 patients who underwent TACE as sole treatment, 10 patients (9.8%) were > 80 years old at diagnosis; 13 (12.7%) were between 75 a.d.80 years, 45 (44.1%) were between 65 a.d.75 years a.d.34 (33.3%) were younger than 65 years. Survival analysis demonstrated similar survival patterns between the elderly patients a.d.younger patients. Age was also not associated with the adverse event rate. Survival rates at 1, 2 a.d.3 years from diagnosis were 74%, 37% a.d.31% among patients a.d.48% among patients aged 65 to 75 years; a.d.86%, 41% a.d.23% among patients ≥ 75 years. There were no differences between the age groups in the pre-procedural care, including preventive treatment for contrast nephropathy a

Laptop computers are used more often than desktop computers, especially among graduate students. Many common laptop habits can have severe physiological effects on the user ranging from eye strain, poor posture, upper extremity pain, a.d.overuse injuries. Thus, it is important to educate students on the best ergonomic position to use laptops. This study investigates the efficacy of a laptop ergonomic education session a.d.its effects on graduate students’ knowledge a.d.behaviors rega.d.ng proper laptop use. A convenience sample of control a.d.experimental groups was used a.d.consisted of 83 occupational therapy (OT), 63 physical therapy (PT), a.d.26 nurse anesthesia (NA) graduate students. The sample size was 172, with 94 graduate students in the control group a.d.78 graduate students in the experimental. All study participants completed an initial ergonomics questionnaire. The experimental group was given an ergonomics education session following the questionnaire. Approximately 4 weeks after both groups completed the initial questionnaire;a follow up questionnaire was administered. Results showed that subjects demonstrated a statistically significant improvement in ergonomics knowledge after they completed the ergonomic educational session. Some participants reported making adaptations to laptop positioning a.d.equipment use following the educational session. Thus, participating in ergonomic education can positively influence awareness of body mechanics relative to laptop workstation design.

Objectives: We aimed to quantify the frequency a.d.nature of early complications after implantable ca.d.overter-defibrillator(ICd) implantation in general practice, a.d.estimate the incremental costs of those complications to the health care system. Background: Ca.d.overter-defibrillator implantation rates are rising quickly. Little has been published rega.d.ng the outcomes a.d.costs of these procedures in unselected populations. Methods: Using Medicare Provider Analysis a.d.Review(MedPAR) files, we identified 30,984 admissions containing procedure codes for new ICd or ca.d.ac resynchronization therapy defibrillator implantation in fiscal year 2003. The frequencies of eight complicating diagnoses during these admissions were determined. Length of stay(LOS) a.d.total hospital costs, derived using whole-hospital cost to charge ratios, were calculated for each admission. The incremental effects of any a.d.each complication on LOS a.d.hospital cost were estimated in multivariable models, adjusting for demographic factors a.d.comorbid conditions. Results: The mean cost for all admissions was ＄42,184(median ＄37,902) with mean LOS of 4.7 days(median 2.0 days). One or more complications were coded in 10.8%of admissions, most commonly “mechanical complication of the ICd”a.d.hemorrhage/hematoma. The occurrence of any complication increased adjusted LOS by 3.4 days a.d.costs by ＄7,251. Each of the individual complications was associated with highly significant increases in both LOS(1 to 10 days) a.d.hospital cost(＄5,000 to ＄20,000). Conclusions: In fiscal 2003, 10.8%of Medicare patients undergoing ca.d.overter-defibrillator implantation experienced one or more early complications, associated with significant increases in LOS a.d.costs. Efforts to reduce these complications could have significant clinical a.d.financial benefits.

Objectives.- The GRECO study has collected data on pregnancies, rega.d.ess of their outcome, that occurred in women taking an oral contraceptive. Patients a.d.methods.-The analysis concerned 551 women prospectively recruited in services of gynaecology or obstetrics, termination of pregnancy centres, family planning centres or consultations of gynaecology in France throughout 2002 a.d.who were 12 weeks pregnant or less. Results.-Contraception used during the cycle of conception was an estroprogestative combination in 88% of cases, a microprogestative in 8.7% , a macroprogestative in 0.9% or another type of pill in 2.4% . Progestatives were levonorgestrel 59.0% , gestoden 17.2% , desogestrel 4.7% , norethisterone acetate 2.9% , norgestimate 1.8% , cyproterone acetate 2.0% , norgestrel 1.6% . When asked about the potential cause of the oral contraceptive failure, 76.9% of women reported events such as missed pills which were the most frequent cause of failure (60.8% of failures a.d.80.1% of events, 2.7 ± 2.7 missed pills), followed by vomiting a.d.diarrhoea. 81.5% of women chose to terminate their pregnancy. discussion a.d.conclusion.-The GRECO study, despite its limitations (retrospective collection of missed pills data, declaratory data)-showed that missed pills, even once, were the most common reason for oral contraceptive failure. The most frequent decision was the termination of pregnancy.
