Deep learning on CT scans to predict checkpoint inhibitor treatment outcomes in advanced melanoma.

Immune checkpoint inhibitor (ICI) treatment has proven successful for advanced melanoma, but is associated with potentially severe toxicity and high costs. Accurate biomarkers for response are lacking. The present work is the first to investigate the value of deep learning on CT imaging of metastatic lesions for predicting ICI treatment outcomes in advanced melanoma.

Continuous decoupled redox electrochemical CO capture.

Electrochemical CO capture driven by renewable electricity holds significant potential for efficient decarbonization. However, the widespread adoption of this approach is currently limited by issues such as instability, discontinuity, high energy demand, and challenges in scaling up. In this study, we propose a scalable strategy that addresses these limitations by transforming the conventional single-step electrochemical redox reaction into a stepwise electrochemical-chemical redox process.

Multidisciplinary team meetings: dynamic routines that (re)make palliative care.

Multidisciplinary team meetings are part of the everyday working life of palliative care staff. Based on ethnographic material from community and hospital palliative care teams in England, this article examines these meetings as dynamic routines. Although intended to have a prescribed format to review deaths and collect standardised information to monitor service performance, in practice, the content and conduct of the meetings were fluid, reflecting how this structure did not always match the concerns held by the team.

Plant Species Richness and the Root Economics Space Drive Soil Fungal Communities.

Trait-based approaches have been increasingly used to relate plants to soil microbial communities. Using the recently described root economics space as an approach to explain the structure of soil-borne fungal communities, our study in a grassland diversity experiment reveals distinct root trait strategies at the plant community level. In addition to significant effects of plant species richness, we show that the collaboration and conservation gradient are strong drivers of the composition of the different guilds of soil fungi.

Spatial proteomic differences in chronic traumatic encephalopathy, Alzheimer's disease, and primary age-related tauopathy hippocampi.

Introduction: Alzheimer's disease (AD), primary age-related tauopathy (PART), and chronic traumatic encephalopathy (CTE) all feature hyperphosphorylated tau (p-tau)-immunoreactive neurofibrillary degeneration, but differ in neuroanatomical distribution and progression of neurofibrillary degeneration and amyloid beta (Aβ) deposition.

Methods: We used Nanostring GeoMx Digital Spatial Profiling to compare the expression of 70 proteins in neurofibrillary tangle (NFT)-bearing and non-NFT-bearing neurons in hippocampal CA1, CA2, and CA4 subregions and entorhinal cortex of cases with autopsy-confirmed AD (n = 8), PART (n = 7), and CTE (n = 5).

Results: There were numerous subregion-specific differences related to Aβ processing, autophagy/proteostasis, inflammation, gliosis, oxidative stress, neuronal/synaptic integrity, and p-tau epitopes among these different disorders.

The versatility of the Supinator to Posterior Interosseus Nerve (SPIN) transfer: Indications and outcomes, a Case Series.

Background: Transfer of the supinator motor branches to the posterior interosseous nerve (SPIN) was first described as a reliable method of restoration of digit extension in cases of paralysis when there is retained function in the 5th and 6th cervical nerve roots with loss of function in the 8th cervical nerve root.

Methods: We performed a retrospective review of all the SPIN transfers that were performed in our unit which included 16 limbs in 14 patients over a 6-year period. The median age was 49 years (range 22-74).

Cytosolic-enhanced dark Epac-based FRET sensors allow for intracellular cAMP detection in live cells via FLIM.

Fluorescence resonance energy transfer (FRET)-based biosensors are powerful tools for studying second messengers with high temporal and spatial resolution. FRET is commonly detected by ratio imaging, but fluorescence lifetime imaging microscopy (FLIM), which measures the donor fluorophore's lifetime, offers a robust and more quantitative alternative. We have introduced and optimized four generations of FRET sensors for cAMP, based on the effector molecule Epac1, including variants for either ratio imaging or FLIM detection.

Environmental Conditions Modulate Warming Effects on Plant Litter Decomposition Globally.

Empirical studies worldwide show that warming has variable effects on plant litter decomposition, leaving the overall impact of climate change on decomposition uncertain. We conducted a meta-analysis of 109 experimental warming studies across seven continents, using natural and standardised plant material, to assess the overarching effect of warming on litter decomposition and identify potential moderating factors. We determined that at least 5.

An umbrella term often used for this spectrum of disorders or conditions is Vascular contributions to Cognitive Impairment and Dementia (VCID). The journal was launched in 2020.

Proteomic profiling of peripheral blood mononuclear cells reveals immune dysregulation and metabolic alterations in kidney transplant recipients with COVID-19.

The COVID-19 pandemic has significantly impacted global health, especially in vulnerable populations like kidney transplant recipients (KTRs). Recently, mass spectrometry-based proteomics has emerged as a powerful tool to shed light on a broad spectrum of dysregulated biological processes in KTRs with COVID-19. In this study, we prospectively collected blood samples from 17 COVID-19-positive KTRs and 10 non-infected KTRs between May and September 2020.

Surgical navigation for targeted retroperitoneal lymph-node removal: a randomised, controlled, phase 3 trial.

Background: Metastatic retroperitoneal lymph node dissection (LND) for nodal recurrence is applied for a variety of cancers, such as urological, gynaecological and rectal cancer. Precise localisation and resection of these lymph nodes (LNs) during surgery can be challenging, especially after previous radiotherapy or surgery. The objective of this study was to assess the added value of surgical navigation for targeted LND in the retroperitoneum.

A comparative evaluation of commercially available short fiber-reinforced composites.

Background: Short fiber-reinforced composites (SFRCs) are restorative materials for large cavities claimed to effectively resist crack propagation. This study aimed to compare the mechanical properties and physical characteristics of five commercially available SFRCS (Alert, Fibrafill Flow, Fibrafill Dentin, everX Flow, and everX Posterior) against a conventional particulate-filled composite (PFC, Essentia Universal).

Methods: The following characteristics were evaluated in accordance with ISO standards: flexural strength and modulus and fracture toughness.

Psychosocial and cognitive determinants of 10-year depressive symptom trajectories in patients with cardiovascular disease: The SMART-Medea study.

Background: Middle-aged and older adults presenting clinically relevant depressive symptoms are often undiagnosed. Understanding the determinants of late-life depressive symptoms could improve prognosis. Further, individuals with manifest cardiovascular disease (CVD) are at an increased risk of depression.

Social frailty in older adults: A concept analysis.

Background: Social frailty has been increasingly prevalent due to the aging populations. This concept is a relatively new topic in the gerontology. Older adults experiencing social isolation because of social frailty remain in a state of loneliness or depression.

High-flow nasal cannula oxygen therapy for children with bronchiolitis: Implementation of a national guideline.

Aim: High flow nasal cannula (HFNC) therapy is a form of respiratory support used in children with bronchiolitis. A national guideline for the use of HFNC was published in The Netherlands in 2020. We studied the implementation and use of this guideline.

Prognostic and Predictive Biomarkers of Oligometastatic NSCLC: New Insights and Clinical Applications.

This review discusses the current data on predictive and prognostic biomarkers in oligometastatic NSCLC and discusses whether biomarkers identified in other stages and widespread metastatic disease can be extrapolated to the oligometastatic disease (OMD) setting. Research is underway to explore the prognostic and predictive value of biological attributes of tumor tissue, circulating cells, the tumor microenvironment, and imaging findings as biomarkers of oligometastatic NSCLC. Biomarkers that help define true OMD and predict outcomes are needed for patient selection for oligometastatic treatment, and to avoid futile treatments in patients that will not benefit from locoregional treatment.

Conservation of structural brain connectivity in people with multiple sclerosis.

Multiple sclerosis (MS) is a neurodegenerative disease that affects the central nervous system. Structures affected in MS include the corpus callosum, connecting the hemispheres. Studies have shown that in mammalian brains, structural connectivity is organized according to a conservation principle, an inverse relationship between intra- and interhemispheric connectivity.

Facing the fear: a narrative review on the potential of pressure training in music.

Music performance anxiety (MPA) is one of the most reported psychological problems among musicians, posing a significant threat to the optimal performance, health, and psychological wellbeing of musicians. Most research on MPA treatment has focused on reducing symptoms of performance anxiety, but complete "cures" are uncommon. A promising addition or alternative that may help musicians enhance their performance under pressure, despite their anxiety, is pressure training (PT).
