Repositioning drugs for rare immune diseases: Hopes and challenges for a precision medicine
Human primary immunodeficiency diseases (PIDs) are a large group of rare diseases and are characterized by a great genetic and phenotypic heterogeneity. A large subset of PIDs is genetically defined, which has a crucial impact for the understanding of the molecular basis of disease and the development of precision medicine. Discovery and development of new therapies for rare diseases has long been de-privileged due to the length and cost of the processes involved. Interest has increased due to stimulatory regulatory and supportive reimbursement environments enabling viable business models. Advancements in biomedical and computational sciences enable the development of rational, designed approaches for identification of novel indications of already approved drugs allowing faster delivery of new medicines. Drug repositioning is based either on clinical analogies of diseases or on understanding of the molecular mode of drug action and mechanisms of the disease. All of these are the basis for the development of precision medicine

Ein neues Verfahren für namensbasierte Zufallsstichproben von Migranten
The set of best methods for sampling mi- grant populations includes name-based sampling. So far this is done using either ad-hoc lists or onomastic dictionaries for the classi cation of names. This paper pro- poses a new name-based procedure, which uses a Bayes-classi er for the n-grams of the name. The new procedure is fault-tol- erant of alternate spellings, and also allows the classi cation of names that are not found in dictionaries. It was tested using the names of about 1.600 foreigners in the PASS panel. Finally, a CATI survey based on the new method in Hesse is described
The importance of harmonising diagnostic criteria sets for pathological grief
Five diagnostic criteria sets for pathological grief are currently used in research. Studies evaluating their performance indicate that it is not justified to generalise findings regarding prevalence rates and predictive validity across studies using different diagnostic criteria of pathological grief. We provide recommendations to move the bereavement field forward
Reciprocal Associations Among Symptom Levels of Disturbed Grief, Posttraumatic Stress, and Depression Following Traumatic Loss:A Four-Wave Cross-Lagged Study
Objective Disturbed grief, operationalized as persistent complex bereavement disorder (PCBD), correlates with, yet differs from posttraumatic stress disorder (PTSD) and depression symptoms. However, knowledge about temporal associations between these symptoms is limited. We aimed to enhance our understanding of the aetiology of loss-related distress by examining temporal associations between PCBD, PTSD, and depression symptom levels. Methods Dutch people (N=172) who lost significant other(s) in a plane disaster completed questionnaires for PCBD, PTSD, and depression 11, 22, 31, and 42 months post-disaster. Results Cross-lagged analyses revealed that changes in PCBD symptom levels have a greater impact on changes in symptom levels of PTSD and depression than vice versa. Conclusion Our findings contradict the notion that PTSD and depression symptoms should be addressed before grief in treatment. Pending replication of our findings in clinical samples, we tentatively conclude that screening and treatment of grief symptoms has potential value in preventing long-lasting distress
Remotely delivered cognitive behavior therapy for disturbed grief during the COVID-19 crisis:Challenges and opportunities
Cognitive behavior therapy (CBT) interventions are effective in alleviating disturbed grief. CBT is typically delivered face-to-face. Government policy during the coronavirus (COVID-19) pandemic (quarantine and social distancing) may impede access to face-to-face therapy. Psychotherapy is now widely delivered remotely. In this article, various points of attention related to the application of CBT for disturbed grief using telephone or videoconferencing (or video calling) services are discussed. Additionally, we explore possible ways in which individual risk factors and stressors connected with COVID-19 can be addressed in treatment. Remote treatment brings challenges but also opportunities to help people in shifting from unhealthy to healthy grieving
Prognostic relevance of acquired uniparental disomy in serous ovarian cancer
BACKGROUND: Acquired uniparental disomy (aUPD) can lead to homozygosity for tumor suppressor genes or oncogenes. Our purpose is to determine the frequency and profile aUPD regions in serous ovarian cancer (SOC) and investigated the association of aUPD with clinical features and patient outcomes.METHODS: We analyzed single nucleotide polymorphism (SNP) array-based genotyping data on 532 SOC specimens from The Cancer Genome Atlas database to identify aUPD regions. Cox univariate regression and Cox multivariate proportional hazards analyses were performed for survival analysis.RESULTS: We found that 94.7% of SOC samples harbored aUPD; the most common aUPD regions were in chromosomes 17q (76.7%), 17p (39.7%), and 13q (38.3%). In Cox univariate regression analysis, two independent regions of aUPD on chromosome 17q (A and C), and whole-chromosome aUPD were associated with shorter overall survival (OS), and five regions on chromosome 17q (A, D-G) and BRCA1 were associated with recurrence-free survival time. In Cox multivariable proportional hazards analysis, whole-chromosome aUPD was associated with shorter OS. One region of aUPD on chromosome 22q (B) was associated with unilateral disease. A statistically significant association was found between aUPD at TP53 loci and homozygous mutation of TP53 (p < 0.0001).CONCLUSIONS: aUPD is a common event and some recurrent loci are associated with a poor outcome for patients with serous ovarian cancer
Validation of skeletal muscle mass assessment at the level of the third cervical vertebra in patients with head and neck cancer
Background: Low skeletal muscle mass (SMM) is associated with adverse outcomes. SMM is often assessed at the third lumbar vertebra (L3) on abdominal imaging. Abdominal imaging is not routinely performed in patients with head and neck cancer (HNC). We aim to validate SMM measurement at the level of the third cervical vertebra (C3) on head and neck imaging. Material and methods: Patients with pre-treatment whole-body computed tomography (CT) between 2010 and 2018 were included. Cross-sectional muscle area (CSMA) was manually delineated at the level of C3 and L3. Correlation coefficients and intraclass correlation coefficients (ICCs) were calculated. Cohen's kappa was used to assess the reliability of identifying a patient with low SMM. Results: Two hundred patients were included. Correlation between CSMA at the level of C3 and L3 was good (r = 0.75, p < 0.01). Using a multivariate formula to estimate CSMA at L3, including gender, age, and weight, correlation improved (r = 0.82, p < 0.01). The agreement between estimated and actual CSMA at L3 was good (ICC 0.78, p < 0.01). There was moderate agreement in the identification of patients with low SMM based on the estimated lumbar skeletal muscle mass index (LSMI) and actual LSMI (Cohen's κ: 0.57, 95%CI 0.45–0.69). Conclusions: CSMA at C3 correlates well with CSMA at L3. There is moderate agreement in the identification of patients with low SMM based on the estimated lumbar SMI (based on measurement at C3) and actual LSMI
Development of Stresses in Cohesionless Poured Sand
The pressure distribution beneath a conical sandpile, created by pouring sand
from a point source onto a rough rigid support, shows a pronounced minimum
below the apex (`the dip'). Recent work of the authors has attempted to explain
this phenomenon by invoking local rules for stress propagation that depend on
the local geometry, and hence on the construction history, of the medium. We
discuss the fundamental difference between such approaches, which lead to
hyperbolic differential equations, and elastoplastic models, for which the
equations are elliptic within any elastic zones present .... This displacement
field appears to be either ill-defined, or defined relative to a reference
state whose physical existence is in doubt. Insofar as their predictions depend
on physical factors unknown and outside experimental control, such
elastoplastic models predict that the observations should be intrinsically
irreproducible .... Our hyperbolic models are based instead on a physical
picture of the material, in which (a) the load is supported by a skeletal
network of force chains ("stress paths") whose geometry depends on construction
history; (b) this network is `fragile' or marginally stable, in a sense that we
define. .... We point out that our hyperbolic models can nonetheless be
reconciled with elastoplastic ideas by taking the limit of an extremely
anisotropic yield condition.Comment: 25 pages, latex RS.tex with rspublic.sty, 7 figures in Rsfig.ps.
