January 2025
Neuroelectronics Research Flanders (NERF), and Department of Neuroscience, KU Leuven, Leuven,
Murayama and Jach point out that we do not sufficiently understand the constructs and mental computations underlying higher-order motivated behaviors. Although this may be generally true, we would like to add and contribute to the discussion by outlining how interdisciplinary research on has advanced the study of learning and curiosity.

Geomicrobiology, Department of Geosciences, University of Tübingen, Tübingen 72076, Germany.
Defects are common features in hematite that arise from deviations from the perfect mineral crystal structure. Vacancy defects have been shown to significantly enhance arsenate (As) immobilization by hematite. However, the contributions from vacancy defects on different exposed facets of hematite have not been fully quantified.

December 2024
Department of Surgery, Tygerberg Hospital, Stellenbosch University, South Africa.
Background: COVID-19 was first identified in Wuhan, China, in December 2019, where it spread over a wide geographic area until it reached the status of a pandemic in 2020. We postulated that patients who were diagnosed with incidental COVID-19, and underwent surgery, did not have a worse outcome due to the COVID-19 virus compared to their counterparts who did not have the virus.
Methods: This retrospective study included surgical patients (COVID-19 incidentals and COVID-19 negatives) who were admitted to the surgical intensive care unit (SICU) at Tygerberg Academic Hospital between 1 May 2020 and 31 December 2021.
Defining the contribution of human error to adverse events in a surgical service.
S Afr J Surg
December 2024
Department of Surgery, University of KwaZulu-Natal, South Africa.
Background: This study aimed to assess the contribution of human error to adverse events over 10 years in a single surgical department in South Africa.
Methods: A retrospective database analysis was undertaken to identify all adverse events, which were further assessed to identify which were error-associated.
Results: A total of 14 237 adverse events occurred between December 2012 and January 2023, of which 7 504 (52.
Comparative study of polymeric nanoparticles and traditional agents in dental implant decontamination.

Faculty of Dentistry, Department of Periodontics, Complutense University of Madrid, Madrid, Spain.
Peri-implant diseases, such as peri-implantitis, affect up to 47% of dental implant recipients, primarily due to biofilm formation. Current decontamination methods vary in efficacy, prompting interest in polymeric nanoparticles (NPs) for their antimicrobial and protein-specific cleaning properties. This study evaluated the efficacy of polymeric nanoparticles (NPs) in decontaminating titanium dental implants by removing proteinaceous pellicle layers and resisting recontamination.
