Unraveling the Connection Between Ion Channels and Pancreatic Stellate Cell Activation.

Quiescent pancreatic stellate cells (PSCs) represent only a very low proportion of the pancreatic tissue, but their activation leads to stroma remodeling and fibrosis associated with pathologies such as chronic pancreatitis and pancreatic ductal adenocarcinoma (PDAC). PSC activation can be induced by various stresses, including acidosis, growth factors (PDGF, TGFβ), hypoxia, high pressure, or intercellular communication with pancreatic cancer cells. Activated PSC targeting represents a promising therapeutic strategy, but little is known regarding the molecular mechanisms underlying the activation of PSCs.

Method: 13,955 adults completing the Major Depression Inventory (MDI) in the Lolland-Falster Health Study questionnaire were included.Multivariate logistic regression on symptoms of depression based on MDI sum score and ICD-10 scores, associated to education, occupation, and financial strain - unadjusted and adjusted for sex and age group.

A scoping review of robustness concepts for machine learning in healthcare.

While machine learning (ML)-based solutions-often referred to as artificial intelligence (AI) solutions-have demonstrated comparable or superior performance to human experts across various healthcare applications, their vulnerability to perturbations and stability to variations due to new environments-essentially, their robustness-remains ambiguous and often overlooked. In this review, we aimed to identify the types of robustness addressed in the literature for ML models in healthcare. A total of 274 eligible records were retrieved from PubMed, Web of Science, IEEE Xplore, and additional sources.

Perifoveal vascular anomalous complex and telangiectatic capillaries: An overview of two entities potentially sharing a common pathophysiology.

Focal capillary ectasia in the macular region can manifest in distinct clinical scenarios, which can be categorized into two main entities: perifoveal vascular anomalous complex (PVAC) and telangiectatic capillaries (TelCaps). PVAC represents a primary, idiopathic condition, whereas TelCaps occur secondary to underlying vascular disorders, including diabetic macular edema and retinal vein occlusion. We provide a comprehensive analysis of these two entities, encompassing their clinical presentations, multimodal imaging findings, histological evidence, and differential diagnosis from other retinal microvascular abnormalities, such as Type 1 macular telangiectasia, adult-onset Coats disease, Type 3 macular neovascularization in age-related macular degeneration, and retinal arterial macroaneurysms.

Long-term pulse pressure trajectories and risk of incident atrial fibrillation: the Tromsø Study.

Background And Aims: Sex-based differences in the association of long-term trends in pulse pressure with future risk of atrial fibrillation (AF) have been explored using data from the population-based Tromsø Study 1986-2016.

Methods: Women (n = 8331) and men (n = 7638) aged ≥20 years who attended at least two of the three Tromsø Study surveys conducted between 1986 and 2001 (the exposure period) were followed up for incident AF throughout 2016 (the follow-up period). Pulse pressure ≥60 mmHg was considered elevated.

Scenarios for the emergence of new miRNA genes in the plant Arabidopsis halleri.

MicroRNAs (miRNAs) are central players of the regulation of gene expression in Eukaryotes. The repertoires of miRNA genes vary drastically even among closely related species, indicating that they are evolutionarily labile. However, the processes by which they originate over the course of evolution and the nature of their progenitors across the genome remain poorly understood.

PHARAOH: A collaborative crowdsourcing platform for phenotyping and regional analysis of histology.

Deep learning has proven capable of automating key aspects of histopathologic analysis. However, its context-specific nature and continued reliance on large expert-annotated training datasets hinders the development of a critical mass of applications to garner widespread adoption in clinical/research workflows. Here, we present an online collaborative platform that streamlines tissue image annotation to promote the development and sharing of custom computer vision models for PHenotyping And Regional Analysis Of Histology (PHARAOH; https://www.

Selective area molecular beam epitaxy of InSb on InP(111)B: from thin films to quantum nanostructures.

InSb is a material of choice for infrared as well as spintronic devices but its integration on large lattice mismatched semi-insulating III-V substrates has so far altered its exceptional properties. Here, we investigate the direct growth of InSb on InP(111)B substrates with molecular beam epitaxial growth. Despite the lack of a thick metamorphic buffer layer for accommodation, we show that quasi-continuous thin films can be achieved using a very high Sb/In flux ratio.

The influence of locus of control, coping strategies and time perspective on post-traumatic growth in survivors with primary breast cancer.

Background: Breast cancer, a potential traumatic stressor, may be accompanied by positive changes, such as post-traumatic growth (PTG), which may allow patients to overcome this stressful event more easily. Our aim was to identify factors associated with PTG in breast cancer survivors (BCSs).

Methods: We conducted a cross-sectional study in Seintinelles volunteers who answered online questionnaires.

Comparative Effects of Glenzocimab and Eptifibatide on Bleeding Severity in 2 Mouse Models of Intracranial Hemorrhage.

Background: Antiplatelet drugs represent potential candidates for protecting the penumbral microcirculation during cerebral ischemia and improving the benefits of arterial recanalization in ischemic stroke. Yet while the efficacy of such adjuvant strategies has been shown to be highly time dependent, antiplatelet therapy at the acute phase of ischemic stroke cannot be envisioned until the diagnosis of stroke and its ischemic nature have been confirmed because of the presumed risk of worsening bleeding in case of intracranial hemorrhage (ICH). Here, we investigated this risk for 2 antiplatelet drugs currently being tested in clinical trials for ischemic stroke, glenzocimab and eptifibatide, in 2 mouse models of ICH.

Bacillary layer detachment: Updates on its clinical and prognostic significance in retinal disease.

Bacillary layer detachment (BALAD) refers to the distinctive splitting at the level of the photoreceptor inner segment myoid and accumulation of intraretinal fluid, as seen on optical coherence tomography (OCT).BALAD is an increasingly recognized OCT biomarker of numerous heterogeneous chorioretinal diseases, including posterior uveitis, age-related macular degeneration and macular neovascularization, neoplastic and paraneoplastic retinal disorders, rhegmatogenous retinal detachment, blunt ocular trauma, and miscellaneous conditions. The recognition of BALAD is clinically relevant because, based on the specific etiology, BALAD may require simple observation, ocular or systemic medical treatment, or even surgical intervention, with subsequent different prognosis.

Chapter 6: SYNDROMIC PRIMARY HYPERPARATHYROIDISM.

Syndromic primary hyperparathyroidism has several features in common: younger age at diagnosis when compared with sporadic primary hyperparathyroidism, often synchronous or metachronous multi-glandular involvement, higher possibility of recurrence, association with other endocrine or extra-endocrine disorders, and suggestive family background with autosomal dominant inheritance. Hyperparathyroidism in multiple endocrine neoplasia type 1 is the most common syndromic hyperparathyroidism. It is often asymptomatic in adolescents and young adults, but may be responsible for recurrent lithiasis and/or bone loss.

Chapter 3: IMPACT OF PRIMARY HYPERPARATHYROIDISM.

At present, primary hyperparathyroidism is most often discovered in an asymptomatic patient, but can sometimes be revealed by a renal or bone complications. In all cases, a full work-up is recommended, with assessment of renal function (glomerular filtration rate), 24-hour calciuria, screening for risk factors for lithiasis, and renal and urinary tract imaging (ultrasound or CT scan) to look for stones or nephrocalcinosis. Bone densitometry, with measurements of the spine, femur and radius, is the recommended reference test for demineralization.

Short- and long-term outcomes of pulmonary emphysema patients on mechanical ventilation admitted to the intensive care unit for acute respiratory failure: A retrospective observational study.

Introduction: Acute respiratory failure is a leading cause of admission to the intensive care unit (ICU), with mortality rates remaining stagnant despite advances in resuscitation techniques. Comorbidities, notably chronic obstructive pulmonary disease, significantly impact ICU patient outcomes. Pulmonary emphysema, commonly associated with chronic obstructive pulmonary disease, poses a significant risk, yet its influence on ICU mortality remains understudied.

Gender differences in the association between adherence to healthy diet principles and adherence to cardiopreventive medication among adults from Québec (Canada).

Adherence to healthy diet principles and to cardiopreventive medication, both key behaviors in cardiovascular disease (CVD) prevention, is known to differ between women and men. Whether these adherence behaviors are differentially related among women and men has never been thoroughly assessed. The objective was to assess gender differences in the association between adherence to healthy diet principles and to cardiopreventive medication in adults free of CVD.

Inflammatory Potential of the Diet and Risk of Crohn's Disease and Ulcerative Colitis.

Background: Association between dietary factors and the risk of developing inflammatory bowel disease (IBD) has been studied extensively. However, identification of deleterious dietary patterns merits further study.

Aim: To investigate the risk of developing Crohn's disease (CD) and ulcerative colitis (UC) according to the inflammatory score of the diet (ISD) in the multinational European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.

IRF5 as a potential immunological biomarker in lung adenocarcinoma.

Background: In the clinic, the primary conventional treatments of advanced non-small cell lung cancer (NSCLC) are surgery, radiation therapy, and chemotherapy. In recent years, immune checkpoint inhibitors (ICIs) have shown promise in optimizing therapeutic benefits when combined with other immunotherapies or standard therapies. However, effective biomarkers for distant metastasis or recurrence have yet to be identified, making it difficult to determine the best therapeutic approaches.

Barriers to and enablers of modifying diet after metabolic bariatric surgery: A systematic review of published literature.

This is a qualitative systematic review in which we investigated barriers and enablers influencing dietary behavior change after metabolic bariatric surgery (MBS). Database searches retrieved publications reporting perceived factors influencing dietary behavior change post-MBS. Data (quotes, survey results, interpretative summaries) were extracted and analyzed using combined deductive and inductive thematic analyses.

Comparison of whole genome sequencing performance from fish swabs and fin clips.

Objective: Fin clipping is the standard DNA sampling technique for whole genome sequencing (WGS) of small fish. The collection of fin clips requires anaesthesia or even euthanisation of the individual. Swabbing may be a less invasive, non-lethal alternative to fin-clipping.

Incidental Findings Identified by Prenatal Microarray Analysis and Consensus Reporting Criteria of the Catalan Public Health Network XIGENICS.

Objective: The study aimed to evaluate the frequency of pathogenic copy number variants (CNVs) classified as incidental findings (IFs) in prenatal diagnosis and to develop consensus recommendations for standardizing their reporting across six centers within the Catalan public health system (XIGENICS network).

Method: A retrospective review of 4219 consecutive prenatal microarrays performed within the network from 2018 to 2023 was conducted, including all referral reasons. To develop consensus recommendations, several discussion meetings were held along with an extensive review of the existing literature.

Methane emissions from the Nord Stream subsea pipeline leaks.

The amount of methane released to the atmosphere from the Nord Stream subsea pipeline leaks remains uncertain, as reflected in a wide range of estimates. A lack of information regarding the temporal variation in atmospheric emissions has made it challenging to reconcile pipeline volumetric (bottom-up) estimates with measurement-based (top-down) estimates. Here we simulate pipeline rupture emission rates and integrate these with methane dissolution and sea-surface outgassing estimates to model the evolution of atmospheric emissions from the leaks.
