Medical Genetics Center (MGZ), Bayerstr. 3-5, 80335, Munich, Germany; NASGE, Nationale Allianz für seltene genetische Erkrankungen, Germany; Department of Medicine IV, Klinikum der Universität, Ludwig-Maximilians-Universität, Ziemssenstr. 5, 80336, Munich, Germany. Electronic address:

As multigene panel testing is becoming routine in clinical care, there are recommendations at national and international level, as to which genes should be analyzed in the context of a hereditary breast and ovarian cancer (HBOC). However, the individual composition of gene panels offered by testing laboratories vary, resulting in a different variant diagnostic rate. Therefore, we performed a retrospective NGS dataset analysis of suspected HBOC patients who had been tested at different German diagnostic laboratories that are part of the NASGE network.

Best practices for including sex as a variable in appetite research.

Appetite

January 2025

Department of Reproductive Endocrinology, University Hospital of Zurich, 8091, Zurich, Switzerland.

Despite increasing recognition that sex is a critical variable in appetite research, many studies fail to include participants of both sexes, fail to consider reproductive physiology in participant selection, or include both sexes but fail to test for sex differences in outcomes. To help remedy this situation, this article seeks to engender enthusiasm for including sex as a variable in appetite research. We first illustrate some sex differences in healthy and disordered eating, including both male-female differences and differences across the menstrual cycle.

Intellectual inflation: one way for scientific research to degenerate.

Stud Hist Philos Sci

January 2025

Munich Centre for the Philosophy of Science, Ludwig Maximilian University of Munich, Office R124, Ludwigstr. 31, D-80539, Munich, Germany. Electronic address:

This paper aims to analyze a specific way in which a scientific programme or area can, in Lakatosian terms, degenerate: namely, through a developmental process of intellectual inflation. Adopting a pluralist approach to the notion of scientific progress, we propose that the historical development of a particular scientific area can be analyzed as being intellectually inflationary during a bounded period of time if it has considerably increased its productive output (thus demonstrating productive progressive) while the overall semantic or epistemic value of those products have not improved in a significant fashion (thus lacking progress in a semantic or epistemic sense). Then, we apply this concept to thoroughly assess whether there have been some intellectually inflationary patterns in the development of (i) information-theoretical evolutionary biology in 1961-2023, and (ii) ensemblist non-equilibrium statistical mechanics in 1938-2023.

Understanding how land use affects temporal stability is crucial to preserve biodiversity and ecosystem functions. Yet, the mechanistic links between land-use intensity and stability-driving mechanisms remain unclear, with functional traits likely playing a key role. Using 13 years of data from 300 sites in Germany, we tested whether and how trait-based community features mediate the effect of land-use intensity on acknowledged stability drivers (compensatory dynamics, portfolio effect, and dominant species variability), within and across plant and arthropod communities.

Transplanted organs are inevitably exposed to ischemia-reperfusion (IR) injury, which is known to cause graft dysfunction. Functional and structural changes that follow IR tissue injury are mediated by neutrophils through the production of oxygen-derived free radicals, as well as from degranulation which entails the release of proteases and other pro-inflammatory mediators. Neutrophil serine proteases (NSPs) are believed to be the principal triggers of post-ischemic reperfusion damage.

RNA-sensing TLRs are strategically positioned in the endolysosome to detect incoming nonself RNA. RNase T2 plays a critical role in processing long, structured RNA into short oligoribonucleotides that engage TLR7 or TLR8. In addition to its positive regulatory role, RNase T2 also restricts RNA recognition through unknown mechanisms, as patients deficient in RNase T2 suffer from neuroinflammation.

J Pers Med

January 2025

Center for Musculoskeletal Surgery, Clinic for Orthopedics, Charité-Universitätsmedizin Berlin, Corporate Member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health, 10117 Berlin, Germany.

Periprosthetic joint infection (PJI) following knee arthroplasty can significantly compromise patient mobility and quality of life. The newly proposed TNM classification system, adapted from oncology, categorizes PJI severity but has not yet been correlated with both subjective and objective outcomes post PJI treatment. This study evaluates the applicability of the TNM classification system for predicting outcomes in knee PJI revision surgeries.

Joint Identification and Sensing for Discrete Memoryless Channels.

Entropy (Basel)

December 2024

Chair of Theoretical Information Technology, Technical University of Munich, 80333 Munich, Germany.

In the identification (ID) scheme proposed by Ahlswede and Dueck, the receiver's goal is simply to verify whether a specific message of interest was sent. Unlike Shannon's transmission codes, which aim for message decoding, ID codes for a discrete memoryless channel (DMC) are far more efficient; their size grows doubly exponentially with the blocklength when randomized encoding is used. This indicates that when the receiver's objective does not require decoding, the ID paradigm is significantly more efficient than traditional Shannon transmission in terms of both energy consumption and hardware complexity.

Assessment of Negative Symptoms in Schizophrenia: From the Consensus Conference-Derived Scales to Remote Digital Phenotyping.

Brain Sci

January 2025

Department of Mental and Physical Health and Preventive Medicine, School of Medicine, University of Campania Luigi Vanvitelli, Largo Madonna delle Grazie 1, 80135 Naples, Italy.

The assessment of negative symptoms in schizophrenia has advanced since the 2006 NIMH-MATRICS Consensus Statement, leading to the development of second-generation rating scales like the Brief Negative Symptom Scale and the Clinical Assessment Interview for Negative Symptoms. These scales address the limitations of first-generation tools, such as the inclusion of aspects that are not negative symptoms and the lack of assessment of the subject's internal experience. However, psychometric validation of these scales is still in progress, and they are not yet recommended by regulatory agencies, thus limiting their use in clinical trials and settings.
