(1) Background: Cirrhosis is associated with frequent alterations in standard coagulation tests that do not adequately reflect hemostasis. Thromboelastography provides a global assessment of coagulation and evaluates the functional status of clotting factors, fibrinogen, platelets, and fibrinolysis. The study aimed to assess whether liver disease severity leads to progressive alterations in the thromboelastography-based assessment of coagulation.

A Stacked Neural Network Model for Damage Localization.

Sensors (Basel)

October 2024

Department of Computer Science, Babeș-Bolyai University, Str. M. Kogălniceanu 1, 400084 Cluj-Napoca, Romania.

Traditional vibration-based damage detection methods often involve human intervention in decision-making, therefore being time-consuming and error-prone. In this study, we propose using Artificial Neural Networks (ANNs) to detect patterns in the structural response and create accurate predictions. The features extracted from the response signal are the Relative Frequency Shifts (RFSs) of the first eight weak-axis bending vibration modes, and the predictions refer to the damage location.

Article Synopsis
  • Cognitive-behavioral therapy (CBT) is identified as the most researched treatment for eating disorders, with a focus on its efficacy in clinical outcomes.
  • A new meta-analysis included 36 trials involving 2,809 participants, highlighting CBT's effectiveness compared to control conditions, especially for binge eating disorder and bulimia nervosa.
  • While the overall effect size for CBT was significant, indicating its benefits, a notable portion of patients still did not achieve sufficient improvement, suggesting the need for further research and alternative treatments.

Article Synopsis
  • Microbial oxidation of volatile alkanes in anoxic environments is crucial for Earth’s biogeochemical cycles.
  • The discovery of alkyl-CoM reductases (ACR) in archaea suggests they can both oxidize and potentially form alkanes, leading to the hypothesis of alkane generation in nature.
  • Research on Candidatus Syntrophoarchaeum shows that the anaerobic oxidation of butane is reversible, indicating that butane, and possible higher volatile alkanes, can be biologically formed, which helps explain their isotopic signatures found in sedimentary basins.

The overestimation of the effect sizes of psychotherapies for depression in waitlist controlled trials: a meta-analytic comparison with usual care controlled trials.

Epidemiol Psychiatr Sci

November 2024

Department of Clinical, Neuro and Developmental Psychology, Amsterdam Public Health research institute, Vrije Universiteit Amsterdam, Amsterdam, the Netherlands.

Aims: There is considerable evidence that waiting list (WL) control groups overestimate the effect sizes of psychotherapies for depression. It is not clear, however, what are the exact causes for this overestimation. We decided to conduct a meta-analytic study to compare trials on psychotherapy for depression with a WL control group against trials with a care-as-usual (CAU) control group.

Objectives: Interval debulking surgery has similar outcomes and less morbidity compared with primary debulking in advanced ovarian cancer. However, there is controversy regarding the selection of chemotherapy-resistant clones. Complete resection is an essential prerequisite, and near-infrared surgery combined with various techniques for highlighting malignant foci strives to achieve actual complete resection.

Interpersonal psychotherapy (IPT) and antidepressant medications are both first-line interventions for adult depression, but their relative efficacy in the long term and on outcome measures other than depressive symptomatology is unknown. Individual participant data (IPD) meta-analyses can provide more precise effect estimates than conventional meta-analyses. This IPD meta-analysis compared the efficacy of IPT and antidepressants on various outcomes at post-treatment and follow-up (PROSPERO: CRD42020219891).

Article Synopsis
  • Climate change is causing avian breeding seasons to start earlier in the temperate zone, leading researchers to explore if this pattern also appears in the timing of nestling ringing dates.
  • The study uses annual median ringing dates from 1951 to 2020 for 9 bird species in Hungary, aiming to offset some data collection biases.
  • Results showed significant advancements in breeding dates (by 9-14 days) for some species, like the Black-headed Gull and Great Tit, while others, like the Common Tern and Long-eared Owl, showed no meaningful changes.

Cancer Prevalence across Vertebrates.

Cancer Discov

January 2025

Arizona Cancer Evolution Center, The Biodesign Institute, Arizona State University, Tempe, Arizona.

Cancer is pervasive across multicellular species, but what explains the differences in cancer prevalence across species? Using 16,049 necropsy records for 292 species spanning three clades of tetrapods (amphibians, sauropsids, and mammals), we found that neoplasia and malignancy prevalence increases with adult mass (contrary to Peto's paradox) and somatic mutation rate but decreases with gestation time. The relationship between adult mass and malignancy prevalence was only apparent when we controlled for gestation time. Evolution of cancer susceptibility appears to have undergone sudden shifts followed by stabilizing selection.
