Studying the intracellular bile acid concentration and toxicity in drug-induced cholestasis: Comprehensive LC-MS/MS analysis with human liver slices.

Drug-induced cholestasis (DIC) is a leading cause of drug-induced liver injury post-drug marketing, characterized by bile flow obstruction and toxic bile constituent accumulation within hepatocytes. This study investigates the toxicity associated with intracellular bile acid (BA) accumulation during DIC development. Using liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis, we examined intracellular BA concentrations in human precision-cut liver slices (PCLS) following the administration of cyclosporin A and chlorpromazine, both with and without an established BA mixture.

Patient-Reported Outcome Measures: A key to patient-tailored and outcome-driven care in Pulmonary Embolism survivors.

Almost half of the acute pulmonary embolism (PE) survivors suffer from long-term sequelae that limit quality of life and their reintegration in society. The post-PE syndrome involves a spectrum of complications ranging from life-threatening pulmonary hypertension to deconditioning and psychosocial issues. The follow-up of acute PE has been demonstrated to be rife with challenges including long diagnostic delays, inefficient use of healthcare resources and the ignorance of psychosocial complications such as depression and anxiety.

Use of alternatives to animal testing for Environmental Safety Assessment (ESA): Report from the 2023 EPAA partners' forum.

Environmental Safety Assessments (ESA) are mandatory for several regulatory purposes and are an important component of stewardship/sustainability initiatives. Fish testing is used for assessing chemical toxicity and bioaccumulation potential; amphibians are included in some jurisdictions and their use is increasing to assess endocrine disruption. Alternative methods are becoming more available, covering the principles of the 3Rs (i.

Factors associated with the residential environment include air and noise pollution, area socioeconomic status, green and blue spaces, and other neighborhood features. This study seeks to quantify the association of selected environmental factors with sleep quality in the daily lives of 211 older adults residing in the Paris metropolitan area with sensor-based methods.

Identifying Patient Subgroups in the Heterogeneous Chronic Pain Population Using Cluster Analysis.

Chronic pain is an ill-defined disease with complex biopsychosocial aspects, posing treatment challenges. We hypothesized that treatment failure results, at least partly, from limited understanding of diverse patient subgroups. We aimed to identify subgroups using psychological variables, allowing for more tailored interventions.

The role of interoception in lifestyle factors: A systematic review.

Background: Interoception, the perception of the internal state of the body, offers an underrepresented and intriguing potential avenue for altering lifestyle-related behaviors. Interoception is intrinsically related to maintaining homeostasis and the flexible allostatic regulation of complex demands. Internal bodily states may also be influenced by lifestyle factors and related problems.

Current trends and evidence on post-TEVAR aorto-pulmonary and -bronchial fistula: a narrative review.

Introduction: Aorto-bronchial or aorto-pulmonary fistulas (ABPF) are a rare but life-threatening complication following thoracic endovascular aortic repair (TEVAR). This narrative review aims to provide an overview of the current trends and available evidence on ABPF following TEVAR, evaluating risk factors, diagnostic approaches, and possible preventive and therapeutic strategies.

Methods: Relevant publications on post-TEVAR ABPF were selected through a literature search on PubMed.

Trends and Updates in the Management and Outcomes of Acute Uncomplicated Type B Aortic Dissection.

Type B aortic dissection (TBAD) presents a complex clinical challenge requiring coordinated, multidisciplinary care to optimize patient outcomes. While rapid intervention is crucial for complicated TBAD, the optimal management of uncomplicated cases remains less well-defined. Historically, uncomplicated TBAD was managed medically, but recent years have seen a shift toward selective interventional approaches.

Local characterization of collagen architecture and mechanical properties of tissue engineered atherosclerotic plaque cap analogs.

Many cardiovascular events are triggered by fibrous cap rupture of an atherosclerotic plaque in arteries. However, cap rupture, including the impact of the cap's structural components, is poorly understood. To obtain better mechanistic insights in a biologically and mechanically controlled environment, we previously developed a tissue-engineered fibrous cap model.

Antisocial personality disorder:Failure to balance excitation/inhibition?

While healthy brain function relies on a dynamic but tightly regulated interaction between excitation (E) and inhibition (I), a spectrum of social cognition disorders, including antisocial behavior and antisocial personality disorder (ASPD), frequently ensuing from irregular neurodevelopment, may be associated with E/I imbalance and concomitant alterations in neural connectivity. Technological advances in the evaluation of structural and functional E/I balance proxies in clinical settings and in human cell culture models provide a general basis for identification of biomarkers providing a powerful concept for prevention and intervention across different dimensions of mental health and disease. In this perspective we outline a framework for research to characterize neurodevelopmental pathways to antisocial behavior and ASPD driven by (epi)genetic factors across life, and to identify molecular targets for preventing the detrimental effects of cognitive dysfunction and maladaptive social behavior, considering psychosocial experience; to validate signatures of E/I imbalance and altered myelination proxies as biomarkers of pathogenic neural circuitry mechanisms to determine etiological processes in the transition from mental health to antisocial behavior and ASPD and in the switch from prevention to treatment; to develop a neurobiologically-grounded integrative model of antisocial behavior and ASPD resultant of disrupted E/I balance, allowing to establish objective diagnoses and monitoring tools, to personalize prevention and therapeutic decisions, to predict treatment response, and thus counteract relapse; and finally, to promote transformation of dimensional disorder taxonomy and to enhance societal awareness and reception of the neurobiological basis of antisocial behavior and ASPD.

Discontinuation of anticoagulants and occurrence of bleeding and thromboembolic events in vitamin K antagonist users with a life-limiting disease.

This cohort study aims to describe (dis)continuation of anticoagulants and incidences of bleeding and thromboembolic events in vitamin K antagonist (VKA) users with a life-limiting disease.

Methods: Data from five Dutch anticoagulation clinics were linked to data from Statistics Netherlands and the Netherlands Cancer registry.

Prevention of bleeding after endoscopic resection of early esophageal neoplasia in patients with esophageal varices: a systematic review.

Background Although endoscopic resection (ER) is recommended as first-choice treatment for early esophageal neoplasia, patients with esophageal varices are considered a high-risk group due to an increased bleeding risk. This systematic review aimed to evaluate the effectiveness and safety of ER in this specific patient category. Methods We searched for studies reporting on clinical outcomes of ER in presence of esophageal varices, irrespective of study design or follow-up time.

Causal Estimands for Analyses of Averted and Avertible Outcomes due to Infectious Disease Interventions.

During the coronavirus disease (COVID-19) pandemic, researchers attempted to estimate the number of averted and avertible outcomes due to vaccination campaigns to quantify public health impact. However, the estimands used in these analyses have not been previously formalized. It is also unclear how these analyses relate to the broader framework of direct, indirect, total, and overall causal effects under interference.

Comparison of model-averaging and single-distribution approaches to estimating species sensitivity distributions and hazardous concentrations for 5% of species.

Estimation of species sensitivity distributions (SSDs) and hazardous concentrations for 5% of species (HC5s) by fitting a statistical distribution to toxicity data for multiple species is essential in ecological risk assessment of chemicals. Given the challenge of selecting the appropriate statistical distribution in SSD estimation, a model-averaging approach that involves fitting multiple statistical distributions and using weighted estimates to derive HC5s is appealing. However, the effectiveness of this approach compared with SSDs based on a single statistical distribution (i.

From social media to artificial intelligence: improving research on digital harms in youth.

In this Personal View, we critically evaluate the limitations and underlying challenges of existing research into the negative mental health consequences of internet-mediated technologies on young people. We argue that identifying and proactively addressing consistent shortcomings is the most effective method for building an accurate evidence base for the forthcoming influx of research on the effects of artificial intelligence (AI) on children and adolescents. Basic research, advice for caregivers, and evidence for policy makers should tackle the challenges that led to the misunderstanding of social media harms.

The UK encourages regular performance monitoring for screen readers. This study aimed to assess the variability in diagnostic performance among readers participating in a wider prospective randomised trial across multiple countries.

Presence and potential impact of anthropogenic nesting materials on a colonial breeding waterbird.

Despite the vital importance of wetlands globally, these habitats have increasingly received anthropogenic materials, such as plastics, which can impact the wildlife these habitats support. Despite commonly found in the nests of Eurasian spoonbill (Platalea leucorodia), the presence of such materials has never been quantified. Here, we monitored the occurrence of anthropogenic nesting materials (ANM) in spoonbill nests in the Camargue wetland in Southern France during two breeding seasons (2021-2022).

Comparison of statistical evaluation approaches for log-removal validation according to European water reuse regulations.

In 2020, the European Union published ordinance EU 2020/741, establishing minimum requirements for water reuse in agriculture. The ordinance differentiates between several water quality classes. For the highest water quality class (Class A), the ordinance mandates analytical validation of the treatment performance of new water reuse treatment plants (WRTP) related to the removal of microbial indicators for viral, bacterial, and parasitic pathogens.

Sources, levels, and determinants of indoor air pollutants in Europe: A systematic review.

Clean air is a requirement for life, and the quality of indoor air is a health determinant since people spend most of their daily time indoors. The aim of this study was to systematically review the available evidence regarding the sources, determinants and concentrations of indoor air pollutants in a set of scenarios under study in K-HEALTHinAIR project. To this end, a systematic review was performed to review the available studies published between the years 2013-2023, for several settings (schools, homes, hospitals, lecture halls, retirement homes, public transports and canteens), conducted in Europe, where sources and determinants of the indoor pollutants concentrations was assessed.

Controlling the stability of monodisperse phospholipid-coated microbubbles by tuning their buckling pressure.

Hypothesis: Monodisperse phospholipid-coated microbubbles, with a size and resonance frequency tuned to the ultrasound driving frequency, have strong potential to enhance sensitivity, efficiency, and control in emerging diagnostic and therapeutic applications involving bubbles and ultrasound. A key requirement is that they retain their gas volume and shell material during physiologic pressure changes and withstand the overpressure during intravenous injection. The shell typically comprises a mixture of a phospholipid (e.

Trajectories of intrinsic connectivity one year post pediatric mild traumatic brain injury: Neural injury superimposed on neurodevelopment.

The developing brain undergoes rapid changes throughout middle childhood and adolescence. The disambiguation of long-term changes in intrinsic activity following pediatric mild traumatic brain injury (pmTBI) from typical development can therefore only be ascertained in longitudinal studies with large sample size and at least three serial assessments. A comprehensive clinical battery and resting-state fMRI data were collected approximately 1-week (N = 263; 8-18 years old), 4-months (N = 192) and 1-year (N = 153) post-injury, with identical visits in a large cohort (N = 228) of age- and sex-matched healthy controls (HC).
