Psychopharmakotherapie in Schwangerschaft und Stillzeit
1998
The primary purpose of this article is to review critically the literature on the use of psychotropic medications in pregnancy and during breast feeding in order to suggest strategies for the clinical management of these periods. Use of psychotropic medications during pregnancy may cause three complications: 1. teratogenicity, 2. perinatal syndromes (neonatal toxicity), and 3. postnatal behavioural sequelae (behavioural toxicity). The literature features few well-controlled studies concerning these points, so that the available information allows only few conclusions. Exposure to certain psychotropic drugs in utero may increase the risk for some specific congenital anomalies; there is mostl…
Contributing factors and outcomes of treatment refusal in pediatric oncology in Germany
2016
Background In Germany, about 1,800 new cases of pediatric cancer under 15 years of age are diagnosed each year and survival rates approach 80%. Although treatment is covered by health insurance and is thus available for all patients at no cost, treatment refusal and treatment discontinuation have been observed. However, no data providing numbers and outcomes for developed countries have been published thus far. Procedure A questionnaire-based survey was performed among German pediatric oncology centers to ascertain the number of treatment refusals among pediatric patients who were diagnosed between January 2008 and December 2009 in Germany. Results Questionnaires from 70 of 73 centers were …
Characteristics and treatment of Multiple Sclerosis-related trigeminal neuralgia: An Italian multi-centre study
2019
Abstract Background The prevalence of trigeminal neuralgia (TN) in Multiple Sclerosis (MS) patients is higher than in the general population and its management can be particularly challenging. Our aim is to describe the characteristics, treatment and prognostic factors of MS-related TN in a retrospective multicentre study. Methods Neurologists members of the RIREMS group (Rising Researchers in MS) enrolled MS patients with a TN diagnosis and filled out a spreadsheet comprising their clinical data. Results Population consisted of 298 patients. First-choice preventive treatments were carbamazepine and oxcarbazepine. A surgical procedure was performed in 81 (30%) patients, most commonly gamma …

Efficacy of ruxolitinib retreatment in a patient with high-risk myelofibrosis using the international prognostic scoring system
2019
Primary myelofibrosis (PMF) is a myeloproliferative neoplasm in which clonal proliferation of hematopoietic stem cells and bone marrow fibrosis coexist.1 Patients may eventually die due to leukemic progression, which occurs in up to 20% of cases, or because of cardiovascular comorbidities or cytopenia, which causes susceptibility to infections and bleeding.2 Myelofibrosis diagnosis relies upon the evaluation of several clinical and laboratory criteria suggested by the World Health Organization (WHO) in 2016.3 The major mutations leading to myelofibrosis usually occur in the JAK2, CALR, and MPL genes. However, in almost 10% of the cases, none of the above-mentioned mutations can be detected …
Two-stage adaptive designs with correlated test statistics.
2005
When performing a trial using an adaptive sequential design, it is usually assumed that the data for each stage come from different units; for example, patients. However, sometimes it is not possible to satisfy this condition or to check whether it is satisfied. In these cases, the test statistics and p-values of each stage may be dependent. In this paper we investigate the type I error of two-stage adaptive designs when the test statistics from the stages are assumed to be bivariate normal. Analytical considerations are performed under the restriction that the conditional error function is constant in the continuation region. We show that the decisions can become conservative as well as an…
Adverse events as potential predictive factors of activity in patients with advanced hepatocellular carcinoma treated with lenvatinib
2021
Background and Aim: Lenvatinib is a standard of care option in first-line therapy of advanced hepatocellular carcinoma (HCC). In the present study, we aim to identify, in patients with HCC treated with lenvatinib, a possible association between occurrence and grading of adverse events (AEs) and outcome. Methods: We performed a retrospective analysis of 606 Japanese and Italian patients treated with lenvatinib in first-line setting and investigated the possible correlation between the onset of AEs, toxicity grade (G) and outcome measures such as overall survival (OS) and progression-free survival (PFS). Results: The appearance of arterial hypertension G ≥ 2 independently predicted prolonged …
Theoretical analysis of the γγ→π0η process
2017
We present a theoretical study of the $\ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\rightarrow}\ensuremath{\pi}\ensuremath{\eta}$ process from the threshold up to 1.4 GeV in the $\ensuremath{\pi}\ensuremath{\eta}$ invariant mass. For the s-wave ${a}_{0}(980)$ resonance state we adopt a dispersive formalism using a coupled-channel Omn\`es representation, while the d-wave ${a}_{2}(1320)$ state is described as a Breit-Wigner resonance. An analytic continuation to the ${a}_{0}(980)$ pole position allows us to extract its two-photon decay width as ${\mathrm{\ensuremath{\Gamma}}}_{{a}_{0}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}}=0.27(4)\text{ }\text{ }\mathrm{keV}$.
The WKB Approximation
2017
In this chapter we shall develop an important semiclassical method which has come back into favor again, particularly in the last few years, since it permits a continuation into field theory. Here, too, one is interested in nonperturbative methods.
Thermal field theories and shifted boundary Conditions
2014
The analytic continuation to an imaginary velocity of the canonical partition function of a thermal system expressed in a moving frame has a natural implementation in the Euclidean path-integral formulation in terms of shifted boundary conditions. The Poincare' invariance underlying a relativistic theory implies a dependence of the free-energy on the compact length L_0 and the shift xi only through the combination beta=L_0(1+xi^2)^(1/2). This in turn implies that the energy and the momentum distributions of the thermal theory are related, a fact which is encoded in a set of Ward identities among the correlators of the energy-momentum tensor. The latter have interesting applications in latti…
