Diagnostic Strategies for Postmenopausal Bleeding
Postmenopausal bleeding (PMB) is a common clinical problem. Patients with PMB have 10%-15% chance of having endometrial carcinoma and therefore the diagnostic workup is aimed at excluding malignancy. Patient characteristics can alter the probability of having endometrial carcinoma in patients with PMB; in certain groups of patients the incidence has been reported to be as high as 29%. Transvaginal sonography (TVS) is used as a first step in the diagnostic workup, but different authors have come to different conclusions assessing the accuracy of TVS for excluding endometrial carcinoma. Diagnostic procedures obtaining material for histological assessment (e.g., dilatation and curettage, hysteroscopy, and endometrial biopsy) can be more accurate but are also more invasive. The best diagnostic strategy for diagnosing endometrial carcinoma in patients with PMB still remains controversial. Future research should be focussed on achieving a higher accuracy of different diagnostic strategies
Naar 20% reductie van voedselverspilling in 2015 : een verkenning van behoeften en kansen
In dit rapport wordt aangegeven wat de belangrijke aanknopingspunten vormen voor vermindering van voedselverspilling, welke aandachtspunten prioriteit hebben voor de korte en lange termijn, en met welke partijen samengewerkt kan worden om de reductiedoelstelling te behalen
g_{\pi \Lambda \Sigma} and g_{K \Sigma \Xi} from QCD sum rules
The coupling constants g_{\pi \Lambda \Sigma} and g_{K \Sigma \Xi} are
calculated in the QCD sum rule approach using the three-point function method
and taking into account the SU(3) symmetry breaking effects. The pattern of
SU(3) breaking appears to be different from that based on SU(3) relations.Comment: revtex, 9 page
A Structured Assessment to Decrease the Amount of Inconclusive Endometrial Biopsies in Women with Postmenopausal Bleeding

Single hospital pathology laboratory. Population. Endometrial biopsy samples of 66 women with postmenopausal bleeding, collected during the usual diagnostic work-up an
Maternal lipid profile in early pregnancy is associated with foetal growth and the risk of a child born large-for-gestational age: a population-based prospective cohort study Maternal lipid profile in early pregnancy and foetal growth
Background: Lipids such as cholesterol and triglycerides play an important role in both maternal and foetal energy
metabolism. Little is known about maternal lipid levels in pregnancy and their effect on foetal growth. The aim of
this study was to assess maternal lipid levels, foetal growth and the risk of small-for-gestational age (SGA) and
large-for-gestational age (LGA).
Methods: We included 5702 women from the Generation R Study, a prospective population-based cohort.
Maternal lipid levels (total cholesterol, triglycerides and high-density lipoprotein cholesterol [HDL-c]) were measured
in early pregnancy (median 13.4 weeks, 90% range [10.5 to 17.2]). Low-density lipoprotein cholesterol (LDL-c),
remnant cholesterol and non-HDL-c were calculated. Foetal growth was measured repeatedly by ultrasound.
Information on birth anthropometrics was retrieved from medical records. A birth weight below the 10th percentile
was defined as SGA and above the 90th percentile as LGA.
Results: Maternal triglyceride and remnant cholesterol levels were associated with increased foetal head
circumference and abdominal circumference growth rates. Triglycerides and remnant cholesterol were positively
associated with the risk of LGA (odds ratio [OR] 1.11, 95% confidence interval [CI] [1.01 to 1.22] and OR 1.11, 95% CI
[1.01 to 1.23], respectively). These associations were independent of maternal pre-pregnancy body mass index, but
not maternal glucose levels. We observed no association between maternal lipids in early pregnancy and SGA. Conclusions: Our study suggests a novel association of early pregnancy triglyceride and remnant cholesterol levels
with foetal growth, patterns of foetal growth and the risk of LGA. Future studies are warranted to explore clinical
implication possibilities
Search for High-energy Neutrinos from Binary Neutron Star Merger GW170817 with ANTARES, IceCube, and the Pierre Auger Observatory
Study of Tau-pair Production in Photon-Photon Collisions at LEP and Limits on the Anomalous Electromagnetic Moments of the Tau Lepton
Tau-pair production in the process e+e- -> e+e-tau+tau- was studied using
data collected by the DELPHI experiment at LEP2 during the years 1997 - 2000.
The corresponding integrated luminosity is 650 pb^{-1}. The values of the
cross-section obtained are found to be in agreement with QED predictions.
Limits on the anomalous magnetic and electric dipole moments of the tau lepton
are deduced.Comment: 20 pages, 9 figures, Accepted by Eur. Phys. J.
Evidence for an Excess of Soft Photons in Hadronic Decays of Z^0
Soft photons inside hadronic jets converted in front of the DELPHI main
tracker (TPC) in events of qqbar disintegrations of the Z^0 were studied in the
kinematic range 0.2 < E_gamma < 1 GeV and transverse momentum with respect to
the closest jet direction p_T < 80 MeV/c. A clear excess of photons in the
experimental data as compared to the Monte Carlo predictions is observed. This
excess (uncorrected for the photon detection efficiency) is (1.17 +/- 0.06 +/-
0.27) x 10^{-3} gamma/jet in the specified kinematic region, while the expected
level of the inner hadronic bremsstrahlung (which is not included in the Monte
Carlo) is (0.340 +/- 0.001 +/- 0.038) x 10^{-3} gamma/jet. The ratio of the
excess to the predicted bremsstrahlung rate is then (3.4 +/- 0.2 +/- 0.8),
which is similar in strength to the anomalous soft photon signal observed in
fixed target experiments with hadronic beams.Comment: 37 pages, 9 figures, Accepted by Eur. Phys. J.
