Towards safe and reliable deep learning for lung nodule malignancy estimation using out-of-distribution detection.

Comput Biol Med

December 2024

Diagnostic Imaging Analysis Group, Medical Imaging Department, Radboud University Medical Center, Geert Grooteplein Zuid 10, 6525 GA, Nijmegen, the Netherlands.

Artificial Intelligence (AI) models may fail or suffer from reduced performance when applied to unseen data that differs from the training data distribution, referred to as dataset shift. Automatic detection of out-of-distribution (OOD) data contributes to safe and reliable clinical implementation of AI models. In this study, we propose a recognized OOD detection method that utilizes the Mahalanobis distance (MD) and compare its performance to widely known classical methods.

Background: Recently, there has been a surge in virtual reality (VR)-based training for upper limb (UL) rehabilitation, which has yielded mixed results. Therefore, we aimed to explore the effects of conventional therapy combined with VR-based training on UL dysfunction during post-stroke rehabilitation.

Methods: Studies published in English before May 2023 were retrieved from PubMed, Embase, and the Cochrane Library.

Among the myriad of complications associated with traumatic brain injury (TBI), impairments in social behaviors and cognition have emerged as a significant area of concern. Animal models of social behavior are necessary to explore the underlying brain mechanisms contributing to chronic social impairments following brain injury. Here, we utilize large-scale brain recordings of local field potentials to identify neural signatures linked with social preference deficits following frontal brain injury.

Different whole-brain computational models have been recently developed to investigate hypotheses related to brain mechanisms. Among these, the Dynamic Mean Field (DMF) model is particularly attractive, combining a biophysically realistic model that is scaled up via a mean-field approach and multimodal imaging data. However, an important barrier to the widespread usage of the DMF model is that current implementations are computationally expensive, supporting only simulations on brain parcellations that consider less than 100 brain regions.

Understanding the differences between functional and structural human brain connectivity has been a focus of an extensive amount of neuroscience research. We employ a novel approach using the multinomial stochastic block model (MSBM) to explicitly extract components that characterize prominent differences across graphs. We analyze structural and functional connectomes derived from high-resolution diffusion-weighted MRI and fMRI scans of 250 Human Connectome Project subjects, analyzed at group connectivity level across 50 subjects.

Background: The 313-variant polygenic risk score (PRS) provides a promising tool for clinical breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed.

Methods: We explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer diagnosis, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 223,316 females without breast cancer diagnosis from the UK Biobank.

Ordinary differential equation models such as the classical SIR model are widely used in epidemiology to study and predict infectious disease dynamics. However, these models typically assume that populations are homogeneously mixed, ignoring possible variations in disease prevalence due to spatial heterogeneity. To address this issue, reaction-diffusion models have been proposed as an alternative approach to modeling spatially continuous populations in which individuals move in a diffusive manner.

Possible scenarios for the spread of mpox outside the endemic focus in Africa.

Int J Infect Dis

December 2024

PandemiX Center, Dept of Science & Environment, Roskilde University, Roskilde, Denmark. Electronic address:

The recent expansion of mpox in Africa is characterized by a dramatic increase in zoonotic transmission (clade Ia) and the emergence of a new clade Ib that is transmitted from human-to-human (H2H) by close contact. Clade Ia does not pose a threat in areas without zoonotic reservoir. But clade Ib may spread widely, as did the clade IIb that since 2022 has spread globally among MSM.

The aim of this study was to analyse the time trends in Barcelona before and during the adverse context of COVID-19, energy crisis, and climate change in 1) the energy poverty (EP) prevalence; 2) the association between EP and health and 3) the impact of EP on health, according to the axes of inequality (sex, age, social class, and country of birth). We conducted a cross-sectional trends study using data from the 2016 and 2021 Barcelona Health Survey. This study clearly recognizes that EP continues to be an important public health problem in the context of Barcelona.

When microplastics meet microalgae: Unveiling the dynamic formation of aggregates and their impact on toxicity and environmental health.

Water Res

December 2024

Key Laboratory of Agro-Forestry Environmental Processes and Ecological Regulation of Hainan Province, Center for Eco-Environment Restoration Engineering of Hainan Province, Hainan University, Haikou 570228, China; School of Environmental Science and Engineering, Hainan University, Haikou 570228, China; College of Environmental and Resource Sciences, Zhejiang University, Hangzhou 310058, China.

Microplastics (MPs) commonly coexist with microalgae in aquatic environments, can heteroaggregate during their interaction, and potentially affect the migration and impacts of MPs in aquatic environments. The hetero-aggregation may also influence the fate of other pollutants through MPs' adsorption or alter their aquatic toxicity. Here, we explored the hetero-aggregation process and its key driving mechanism that occurred between green microalga Chlorella vulgaris (with a cell size of 2-10 μm) and two types of MPs (polystyrene and polylactide, 613 μm).

Mucosal secretory IgA (SIgA) produced by subepithelial plasma cells in the lamina propria is the major antigen-specific defense mechanism against mucosal infections. We investigated if a retinoic acid (RA)-containing adjuvant in parenteral immunization, can induce vaccine-specific SIgA in the jejunal lumen in a dose-dependent manner in neonatal pigs immunized with a Chlamydia hybrid antigen. To accurately quantify SIgA responses in mucosal secretions, an antigen-specific ELISA method with secondary detection of porcine secretory component rather than IgA was developed.

The use of activated sludge models (ASMs) is a common way in the field of wastewater engineering in terms of plant design, development, optimization, and testing of stand-alone treatment plants. The focus of this study was the development of a joint control system (JCS) for a municipal wastewater treatment plant (mWWTP) and an upstream industrial wastewater treatment plant (iWWTP) to create synergies for saving aeration energy. Therefore, an ASM3 + BioP model of the mWWTP was developed to test different scenarios and to find the best set-points for the novel JCS.

This study investigates the intricate dynamics underlying lipase performance in organic solvents using comprehensive molecular dynamics (MD) simulations, supported by enzyme kinetics data. The study reveals that a single criterion can neither predict nor explain lipase activity in organic solvents, indicating the need for a comprehensive approach. Three lipases were included in this study: lipase B (CALB), lipase (RML), and lipase (TLL).

Background: Intermediate-high risk pulmonary embolism (PE) carries a significant risk of hemodynamic deterioration or death. Treatment should balance efficacy in reducing clot burden with the risk of complications, particularly bleeding. Previous studies on high-dose, short-term thrombolysis with alteplase (rtPA) showed a reduced risk of hemodynamic deterioration but no change in mortality and increased bleeding complications.
