The QIBA Profile for Dynamic Susceptibility Contrast MRI Quantitative Imaging Biomarkers for Assessing Gliomas.

The dynamic susceptibility contrast (DSC) MRI measures of relative cerebral blood volume (rCBV) play a central role in monitoring therapeutic response and disease progression in patients with gliomas. Previous investigations have demonstrated promise of using rCBV in classifying tumor grade, elucidating tumor viability after therapy, and differentiating pseudoprogression and pseudoresponse. However, the quantification and reproducibility of rCBV measurements across patients, devices, and software remain a critical barrier to routine or clinical trial use of longitudinal DSC MRI in patients with gliomas.

Member Adherence to a Health Insurer-Sponsored Gap Closure Program Using Multi-Target Stool DNA Test for Colorectal Cancer Screening.

Objectives: To describe member adherence to a mail-based, health insurer-sponsored gap closure program for colorectal cancer (CRC) screening using multi-target stool DNA (mt-sDNA; Cologuard) tests.

Methods: Combined patient data from Exact Sciences Laboratories LLC and data from mass-mailed mt-sDNA orders placed by a large Medicare Advantage Insurance Plan were analyzed (03/01/2023-06/30/2023). Adherence and time to test return were the primary and secondary outcomes, respectively.

Nonadjacent dependencies and sequential structure of chimpanzee action during a natural tool-use task.

Many of the complex behaviours of humans involve the production of nonadjacent dependencies between sequence elements, which in part can be generated through the hierarchical organization of sequences. To understand how these structural properties of human behaviours evolved, we can gain valuable insight from studying the sequential behaviours of nonhuman animals. Among the behaviours of nonhuman apes, tool use has been hypothesised to be a domain of behaviour which likely involves hierarchical organization, and may therefore possess nonadjacent dependencies between sequential actions.

Robust self-supervised denoising of voltage imaging data using CellMincer.

Voltage imaging is a powerful technique for studying neuronal activity, but its effectiveness is often constrained by low signal-to-noise ratios (SNR). Traditional denoising methods, such as matrix factorization, impose rigid assumptions about noise and signal structures, while existing deep learning approaches fail to fully capture the rapid dynamics and complex dependencies inherent in voltage imaging data. Here, we introduce CellMincer, a novel self-supervised deep learning method specifically developed for denoising voltage imaging datasets.

International consensus statement on microbiome testing in clinical practice.

There is growing interest in the potential exploitation of the gut microbiome as a diagnostic tool in medicine, but evidence supporting its clinical usefulness is scarce. An increasing number of commercial providers offer direct-to-consumer microbiome diagnostic tests without any consensus on their regulation or any proven value in clinical practice, which could result in considerable waste of individual and health-care resources and potential drawbacks in the clinical management of patients. We convened an international multidisciplinary expert panel to standardise best practices of microbiome testing for clinical implementation, including recommendations on general principles and minimum requirements for their provision, indications, pre-testing protocols, method of analyses, reporting of results, and potential clinical value.

Model for an International Case Sharing Program to Enhance Global Palliative Care Education.

Context: In Thailand, the field of palliative medicine is growing but access and training remain limited. We sought to expand education of resident physicians at Chiang Mai University (CMU) in Thailand through development of an international case sharing program.

Objectives: The goals of this project were to increase knowledge of core palliative care topics, to cultivate a culture of reflective clinical practice, and to create a model for collaboration in international palliative care education that can be replicated by other institutions.

Prevalence and characteristics of online child sexual victimization: Findings from the Australian Child Maltreatment Study.

Background: Online child sexual victimization is increasingly facilitated by technology, but evidence of its prevalence and characteristics remains scarce. Reliable population-based data is critical to understand the magnitude and nature of the problem, and inform evidence-based prevention.

Objective: To determine the prevalence of nonconsensual sharing of sexual images of the child by any perpetrator, and of online sexual solicitation by any adult perpetrator; and to determine the characteristics of these experiences.

Detecting and Mitigating the Clever Hans Effect in Medical Imaging: A Scoping Review.

The Clever Hans effect occurs when machine learning models rely on spurious correlations instead of clinically relevant features and poses significant challenges to the development of reliable artificial intelligence (AI) systems in medical imaging. This scoping review provides an overview of methods for identifying and addressing the Clever Hans effect in medical imaging AI algorithms. A total of 173 papers published between 2010 and 2024 were reviewed, and 37 articles were selected for detailed analysis, with classification into two categories: detection and mitigation approaches.

Single-port robotic transanal minimally invasive surgery (SPR-TAMIS): another giant leap forward?

Aim: Minimally invasive transanal platforms are now the standard of care for select low-risk rectal tumours. However, existing platforms come with persistent technical challenges. The da Vinci SP Surgical System™ offers a new alternative designed to work effectively in narrow spaces.

Atmospheric deposition of pollutants at three altitudes on Mount Emei, Sichuan Basin, southwestern China.

Comparing the atmospheric deposition chemistry between above and below the planetary boundary layer (PBL) may help understand the impacts from inter-regional air pollutant transport and local emissions to air pollutant deposition. In this study, we monitored ions, soluble and insoluble potentially toxic elements (PTEs), and dissolved organic nitrogen and carbon at the base (M-base: 551 m asl), middle (M-middle: 2400 m asl), and summit (M-summit: 3077 m asl) on Mount Emei. The annual volume-weighted mean (VWM) concentrations of all measured components were substantially higher at M-base than at M-summit, except for Na, Cl, and NO as Na and Cl at M-summit may be largely from ocean and NO to NO transformation may be faster at M-base.

Best Practices for Delivering Neoadjuvant Therapy in Pancreatic Ductal Adenocarcinoma.

Importance: Neoadjuvant therapy (NT) is an increasingly used treatment strategy for patients with localized pancreatic ductal adenocarcinoma (PDAC). Little research has been conducted on cancer care delivery during NT, and the standards for optimal delivery of NT have not been defined.

Objective: To develop consensus best practices for delivering NT to patients with localized PDAC.

GLP-1 Receptor Agonists Alleviate Diabetic Kidney Injury via β-Klotho-Mediated Ferroptosis Inhibition.

Semaglutide (Smg), a GLP-1 receptor agonist (GLP-1RA), shows renal protective effects in patients with diabetic kidney disease (DKD). However, the exact underlying mechanism remains elusive. This study employs transcriptome sequencing and identifies β-Klotho (KLB) as the critical target responsible for the role of Smg in kidney protection.

Minnesota Hospitals' Plans for Implementing Statewide Guidance on Allocation of Scarce Critical Care Resources During the COVID-19 Pandemic.

Objectives: To assess hospitals' plans for implementing Minnesota's statewide guidance for allocating scarce critical care resources during the COVID-19 pandemic.

Patients And Methods: Individuals from 23 hospitals across Minnesota were invited to complete a 25-item survey between July 20, 2020, and September 18, 2020 to understand how hospitals in the state intended to operationalize statewide clinical triage instructions for scarce resources (including mechanical ventilation) and written ethics guidance on the allocation of critical care resources in the event crisis standards of care triggered triage.

Results: Of individuals invited from 23 hospitals, 14 hospitals completed the survey (60.
