Psychological interventions to prevent the onset of major depression in adults: a systematic review and individual participant data meta-analysis.

Background: Psychological interventions are increasingly discussed as a method to prevent major depressive disorder (MDD) in adults who already experience subthreshold depressive symptoms. In this individual participant data meta-analysis, we quantify the effect of preventive interventions against control on MDD onset in this population, and explore effect modifiers.

Methods: In this systematic review and individual participant data meta-analysis, we screened full-texts of eligible studies within the Metapsy research domain for articles on psychological interventions for depression, from database inception to May 1, 2023, published in English, German, Spanish, and Dutch.

Proteome-wide CETSA reveals new step in apoptosis control.

Apoptosis, a well-established program of cell death, is fundamental to all multicellular organisms. Recent studies of apoptosis initiation events using proteome-wide cellular thermal shift assay (CETSA) have revealed a novel regulatory mechanism involving the cleavage of nuclear substrates. This finding suggests a previously unrecognized amplification step in apoptosis occurring within the nucleus.

The tumor-neutrophil interactions in the microenvironment of brain metastases with different primary sites.

Brain metastases (BrM) originating from lung and breast cancer can recruit and activate neutrophils to acquire a tumor-promoting phenotype. It is currently unclear if this phenomenon also occurs in BrM arising from other primary sites. Here, we investigated the effect of tumor cells isolated from melanoma, lung and gastrointestinal (GI) cancer BrM on neutrophil biology and functions.

Personality functioning and mental distress in leaders of small- and medium sized enterprises.

Objective: For leaders of small and medium-sized enterprises (SMEs) grappling with diverse tasks and stressors, personality functioning can play a key role on stress perception and building and managing professional relationships. We investigated the relationship between SME leaders' personality functioning on the dimensions of self-perception and self-regulation on perceived stress reactivity (PSR), and symptoms of anxiety and depression.

Methods: A cross-sectional sub analysis of a multi-centre RCT project was performed.

Development of MHz X-ray phase contrast imaging at the European XFEL.

We report on recent developments that enable megahertz hard X-ray phase contrast imaging (MHz XPCI) experiments at the Single Particles, Clusters, and Biomolecules and Serial Femtosecond Crystallography (SPB/SFX) instrument of the European XFEL facility (EuXFEL). We describe the technical implementation of the key components, including an MHz fast camera and a modular indirect X-ray microscope system based on fast scintillators coupled through a high-resolution optical microscope, which enable full-field X-ray microscopy with phase contrast of fast and irreversible phenomena. The image quality for MHz XPCI data showed significant improvement compared with a pilot demonstration of the technique using parallel beam illumination, which also allows access to up to 24 keV photon energies at the SPB/SFX instrument of the EuXFEL.

Post-COVID recovery is faster after an infection with the SARS-CoV-2 Omicron variant: a population-based cohort study.

Purpose: Post-COVID-19 condition (PCC) poses a substantial burden to affected individuals, health care systems, and society as a whole. We examined factors associated with recovery from PCC, focusing on the vaccination status prior to infection and the virus variant.

Methods: Our analyses are based on the population-based cohort study for digital health research in Germany (DigiHero).

Effects of High Altitude and Diet on Gastric Disease Severity in Helicobacter pylori Infection in Peru.

Helicobacter pylori is a bacterium that infects approximately half of the world's population, being more prevalent in low- and middle-income countries. H. pylori can cause gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue lymphoma, and gastric cancer, which is among the five most frequent cancers worldwide.

LeAf Trauma- an intersectoral prospective multicenter study assessing quality of life and return to work after majortrauma-study protocol.

With increasing survival rates, the functional outcome and quality of life of trauma patients are gaining more importance. Survivors suffer from chronic pain, psychosomatic disorders, and unemployment as well as increased post-traumatic morbidity, which can lead to an impaired quality of life. So far, the TraumaRegister DGU® records patient data during in-hospital treatment.

Bibliometric analysis of imaging and treatment strategies for severe tricuspid regurgitation from 2015 to 2023.

Background: Severe tricuspid regurgitation is a progressive disease with an unfavourable prognosis. In recent years there have been extraordinary gains in knowledge through both clinical and basic scientific work. We performed a bibliometric analysis on tricuspid regurgitation with a focus on imaging techniques and treatment approaches and to identify scientific milestones and emerging research trends.

Stiffness of elastic cuffs affects physiological and perceptual responses but not motor performance fatigue during low external load resistance exercise with practical blood flow restriction.

Practical blood flow restriction (pBFR), using non-pneumatic elastic cuffs, is a feasible and cost-effective alternative to pneumatic systems. There is evidence that cuff stiffness influences haemodynamic and perceptual responses in the upper body during rest. However, the impact of cuff stiffness during exercise is still unknown.

Impact of Pseudomonas aeruginosa carriage on intensive care unit-acquired pneumonia: a European multicentre prospective cohort study.

Objectives: Pseudomonas aeruginosa (PA) is a common causative pathogen of pneumonia acquired in the intensive care unit (ICU). The aim of this study was to determine the incidence of PA ICU pneumonia (PAIP) and to quantify its independent association with PA colonization at different body sites.

Methods: Adult patients on mechanical ventilation at ICU admission were prospectively enrolled across 30 European ICUs.

Sex-Disaggregated Analysis of Central Venous Catheter-Related Bloodstream Infections in Patients with Cancer.

Introduction: Men are generally more susceptible to bacterial infections than women. Central venous catheters (CVCs), often used to administer systemic treatment in patients with cancer, are an important source of infection. However, little is known about sex-specific differences of CVC-related bloodstream infections (CRBSIs) in patients with cancer.

The Crosstalk of Apoptotic and Non-Apoptotic Signaling in CD95 System.

The mechanisms of CD95 (Fas/APO-1)-mediated extrinsic apoptotic pathway in cancer cells have been extensively studied. The majority of human cells express CD95, but not all these cells can induce extrinsic apoptosis. Accumulating evidence has shown that CD95 is a multifunctional protein, and its stimulation can also elicit non-apoptotic or even survival signals.

Cerebral hyperactivation across the Alzheimer's disease pathological cascade.

Neuronal dysfunction in specific brain regions or across distributed brain networks is a known feature of Alzheimer's disease. An often reported finding in the early stage of the disease is the presence of increased functional MRI (fMRI) blood oxygenation level-dependent signal under task conditions relative to cognitively normal controls, a phenomenon known as 'hyperactivation'. However, research in the past decades yielded complex, sometimes conflicting results.

Downregulation of the keratins CK13 and CK14 does not significantly affect cell viability of human urinary bladder carcinoma cells.

Introduction: Bladder cancer is the ninth most common tumour entity worldwide. Aberrant expression of different keratins has been described in bladder cancer, which is used for diagnostic purposes, but it can also have prognostic value. However, not all keratins have been analysed in bladder cancer, and whether keratins are important for cell viability of bladder cancer tumour cells is not yet known.

3D-cell phantom-experimental setup to assess thermal effects and cell viability of lung tumor cells after electroporation.

Medical devices and technologies must undergo extensive testing and validation before being certified for public healthcare use, especially in oncology where a high research focus is on new advancements. Human 3D-tissue models can offer valuable insights into cancer behavior and treatment efficacy. This study developed a cell phantom setup using a rattail collagen-based hydrogel to facilitate reproducible investigations into ablation techniques, focusing on electroporation (EP) for lung tumor cells.

Subjective social status and health-related quality of life after critical illness: results from a three-year prospective cohort study.

Subjective Social Status (SSS) reflects one's perceived rank within a given social structure and has been shown to be a unique correlate of physical and mental health. However, no research has been conducted to address populations of (recovering) critically ill patients. To shed light on the relationship between SSS and health in critically ill patients, we focus on survivors of acute respiratory distress syndrome (ARDS).

Early life stress induces decreased expression of CB1R and FAAH and epigenetic changes in the medial prefrontal cortex of male rats.

Several studies in both animal models and in humans have provided substantial evidence that early life stress (ELS) induces long-term changes in behavior and brain function, making it a significant risk factor in the aetiology of various mental disorders, including anxiety and depression. In this study, we tested the hypothesis that ELS in male rats (i) leads to increased anxiety and depressive-like symptoms; and (ii) that these behavioral changes are associated with functional alterations in the endocannabinoid system of the medial prefrontal cortex (mPFC). We further assessed whether the predicted changes in the gene expression of two key components of the endocannabinoid system, cannabinoid receptor 1 (CB1R) and the fatty acid amide hydrolase (FAAH), are regulated by epigenetic mechanisms.

Immune response to topical sodium lauryl sulfate differs from classical irritant and allergic contact dermatitis.

Sodium lauryl sulfate (SLS) is used as a control irritant in patch testing for allergic contact dermatitis (ACD). However, up to 20% of those tested react to SLS, whereby the pathophysiological basis of this reaction is still unclear. To mimic patch test reactions, we repeatedly applied SLS to the skin of wild-type mice.
