Surgical management of thymic tumors: a narrative review with focus on robotic-assisted surgery.

Background And Objective: Thymic epithelial tumors, including thymomas and thymic carcinomas, represent the most common mediastinal tumors and account for up to 50% of all anterior mediastinal tumors. For early stages of these thymic tumors, complete resection of the entire thymus is the recommended treatment. The transition from open surgery to video-assisted thoracoscopic surgery (VATS) and recently to robotic-assisted thoracic surgery (RATS) has fundamentally altered the treatment of thymic tumors.

Pyopericardium with cardiac tamponade caused by pyogenic liver abscess: a case report.

Introduction: Purulent bacterial pericarditis is a potentially fatal disease with mortality rates reaching 100% if left untreated.

Case Presentation: We present the case of a 33-year-old Caucasian male patient who developed cardiac tamponade, most likely caused by a pyogenic liver abscess communicating with the pericardium. Treatment with antibiotics, extended sepsis therapy, and drainage of the abscess led to a full recovery.

Impact of Complications on Survival Outcomes in Different Temporary Mechanical Circulatory Support Techniques: A Large Retrospective Cohort Study of Cardiac Surgical and Non-surgical Patients.

Background: Temporary mechanical circulatory support (tMCS) devices have become a standard treatment option in cardiogenic shock but are associated with high complication rates. This study analyzes common complications associated with modern tMCS devices and their impact on mortality depending on the tMCS approach.

Methods: We conducted a retrospective single-center analysis of patients with all-cause cardiogenic shock treated with veno-arterial extracorporeal life support, microaxial flow pump, and a combination of both (ECMELLA).

Left Ventricular Unloading With Surgically Implanted Microaxial Flow Pump in Patients on Venoarterial Membrane Oxygenation.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is applied for the treatment of cardiogenic shock. Concomitant left ventricular unloading (LVU) with a microaxial flow pump (mAFP) enables myocardial and pulmonary recovery and may overcome some of the limitations of VA-ECMO. The study included 145 cardiogenic shock patients, 89 (61.

Enhanced recovery after minimally invasive cardiac surgery following a zero ICU concept-a propensity score-matched analysis.

Objectives: This study investigates our enhanced recovery after minimally invasive cardiac surgery program "enhanced recovery after minimally invasive cardiac surgery" (ERMICS) following a 'Zero ICU' concept compared to standard-of-care treatment in terms of safety and clinical efficacy.

Methods: All patients who underwent minimally invasive mitral valve surgery for primary severe mitral valve regurgitation between 2021 and 2023 were included. Propensity score matching (2:1) was performed between patients who received standard-of-care treatment and those who underwent ERMICS.

Learning tracheal intubation with a hyperangulated videolaryngoscopy blade: sub-analysis of a randomised controlled trial.

Introduction: The number of tracheal intubation attempts required to reach proficiency in videolaryngoscopy with hyperangulated blades is unknown. Understanding this training requirement might guide training for clinicians who perform laryngoscopy. We therefore performed a planned sub-analysis of a randomised controlled trial comparing tracheal intubation success with videolaryngoscopy vs.

[Long-/Post-COVID symptoms in a hotspot collective of the first wave of the SARS-CoV-2 pandemic in Germany].

Introduction: Despite a high number of long/post-COVID cases and an enormous psychological strain on the part of the patients, no scientific consensus has yet been reached on a clearly defined disease entity. The comprehensive media coverage has made the public more sensitive to this topic, which makes it more difficult to take an objective perspective.

Methods: We report on long/post-COVID symptoms in a hotspot collective of the first SARS-CoV-2 wave of infections in Germany; these infections began in Spring 2020 and therefore preceded the start of an intensive media coverage.

Dopamine neurons that inform Drosophila olfactory memory have distinct, acute functions driving attraction and aversion.

The brain must guide immediate responses to beneficial and harmful stimuli while simultaneously writing memories for future reference. While both immediate actions and reinforcement learning are instructed by dopamine, how dopaminergic systems maintain coherence between these 2 reward functions is unknown. Through optogenetic activation experiments, we showed that the dopamine neurons that inform olfactory memory in Drosophila have a distinct, parallel function driving attraction and aversion (valence).

[Management of adult bronchiectasis - Consensus-based Guidelines for the German Respiratory Society (DGP) e. V. (AWMF registration number 020-030)].

Bronchiectasis is an etiologically heterogeneous, chronic, and often progressive respiratory disease characterized by irreversible bronchial dilation. It is frequently associated with significant symptom burden, multiple complications, and reduced quality of life. For several years, there has been a marked global increase in the prevalence of bronchiectasis, which is linked to a substantial economic burden on healthcare systems.

Comparison and combination of mutation and methylation-based urine tests for bladder cancer detection.

Background And Aims: Several non-invasive tests for detecting bladder cancer (BC) are commercially available and are based on detecting small panels of BC-associated mutations and/or methylation changes in urine DNA. However, it is not clear which type of biomarker is best, or if a combination of the two is needed. In this study we address this question by taking a 23-gene mutation panel (GALEAS™ Bladder, GB) and testing if adding a panel of methylation markers improves the sensitivity of BC detection.

The chromatin landscape of high-grade serous ovarian cancer metastasis identifies regulatory drivers in post-chemotherapy residual tumour cells.

Disease recurrence following chemotherapy is a major clinical challenge in ovarian cancer (OC), but little is known regarding how the tumour epigenome regulates transcriptional programs underpinning chemoresistance. We determine the single cell chromatin accessibility landscape of omental OC metastasis from treatment-naïve and neoadjuvant chemotherapy-treated patients and define the chromatin accessibility profiles of epithelial, fibroblast, myeloid and lymphoid cells. Epithelial tumour cells display open chromatin regions enriched with motifs for the oncogenic transcription factors MEIS and PBX.

The Molecular Nature of Redox-Conductive Metal-Organic Frameworks.

ConspectusRedox-conductive metal-organic frameworks (RC-MOFs) are a class of porous materials that exhibit electrical conductivity through a chain of self-exchange reactions between molecularly defined, neighboring redox-active units of differing oxidation states. To maintain electroneutrality, this electron hopping transport is coupled to the translocation of charge balancing counterions. Owing to the molecular nature of the redox active components, RC-MOFs have received increasing attention for potential applications in energy storage, electrocatalysis, reconfigurable electronics, etc.

Single-cell analysis identifies distinct macrophage phenotypes associated with prodisease and proresolving functions in the endometriotic niche.

Endometriosis negatively impacts the health-related quality of life of 190 million women worldwide. Novel advances in nonhormonal treatments for this debilitating condition are desperately needed. Macrophages play a vital role in the pathophysiology of endometriosis and represent a promising therapeutic target.

Evaluating Nondestructive Quantification of Composition Gradients in Metal-Organic Frameworks by MeV Ion Microbeam Analysis.

We evaluate a method to quantify composition depth gradients in intact metal-organic framework (MOF) single crystals and thereby derive diffusion coefficients of postsynthetically incorporated active sites by nondestructive ion-beam microanalysis. Zr-based UiO-67-bpy (bpy = 2,2'-bipyridine-5,5'-dicarboxylic acid) MOFs were synthesized on Si substrates and then metalated postsynthetically with NiCl for 2-48 h, resulting in different Ni depth distributions. Simultaneous micro-Rutherford backscattering spectrometry (μ-RBS) and micro-particle induced X-ray emission (μ-PIXE) analysis were used for the spatially resolved chemical analysis of the MOF single crystals.

Hemocompatibility-related Adverse Events in Patients With Temporary Mechanical Circulatory Support: The Scoring Haemostasis Events and Assessment for Risk (SHEAR) Score.

Evaluation of treatment outcomes in patients supported by temporary mechanical circulatory support (tMCS) currently relies mainly on mortality, which may not sufficiently address other patient benefits or harms. Bleeding and thrombosis are major contributors to mortality. Still, current bleeding scores are not designed for critically ill patients undergoing tMCS, only consider selected populations, and do not account for the high heterogeneity among bleeding and thrombotic adverse events.

Non-Ionic Peterson-Type Olefination Reactivity and its Use in a Silicon-Promoted Carbonyl-Carbonyl Cross Coupling Reaction.

The [2+2] cycloaddition reaction between the Si=C double bond of adamantylsilene and the carbonyl group of aliphatic, aromatic or acetylenic ketones and aldehydes is demonstrated. The product of this reaction that is central to a non-ionic version of the Peterson olefination is an unusual four-membered 1,2-silaoxetane heterocycle that was characterized spectroscopically and crystallographically. In the presence of SiO, the silaoxetane undergoes retro-cycloaddition with the formation of alkene products.

Optimizing post-synthetic metal incorporation in mixed-linker MOFs: insights from metalation studies on bipyridine-containing UiO-67 single crystals.

The postsynthetic metalation (PSM) of metal-organic frameworks (MOFs) with intrinsic metal binding sites is an intriguing strategy to introduce catalytic function into MOFs. The spatial distribution of the catalytic sites within the MOF crystal will affect the efficiency of the material, but the factors that govern depth distribution of the introduced metal sites are often not well understood. Herein, we employ Rutherford backscattering spectrometry (RBS) to investigate the metal distribution in a series of post-synthetically metalated mixed linker bpdc/BPY UiO-67 (UiO = Universitet i Oslo, bpdc = biphenyl-dicarboxylate, BPY = 2,2'-bipyridine-5,5'-dicarboxylate) single crystals as a function of linker ratio and metalation time.

Intrinsic or Nonintrinsic End-stage Liver Disease and Its Association With Thromboelastography-based Coagulation States in Patients Undergoing Liver Transplantation: A Retrospective Cohort Study.

Objectives: Perioperative coagulation management in liver transplantation recipients is challenging. Viscoelastic testing with rotational thromboelastography (TEG) can help quantify hemostatic profiles. The current work aimed to investigate whether the etiology of end-stage liver disease, pretransplant disease severity, or pretransplant thrombotic or bleeding complications are associated with specific TEG patterns.

Temporal progression of tau pathology and neuroinflammation in a rhesus monkey model of Alzheimer's disease.

Introduction: The understanding of the pathological events in Alzheimer's disease (AD) has advanced dramatically, but the successful translation from rodent models into efficient human therapies is still problematic.

Methods: To examine how tau pathology can develop in the primate brain, we injected 12 macaques with a dual tau mutation (P301L/S320F) into the entorhinal cortex (ERC). An investigation was performed using high-resolution microscopy, magnetic resonance imaging (MRI), positron emission tomography (PET), and fluid biomarkers to determine the temporal progression of the pathology 3 and 6 months after the injection.

The effect of high-dose selenium on mortality and postoperative organ dysfunction in post-cardiotomy cardiogenic shock patients supported with mechanical circulatory support - A post-hoc analysis of the SUSTAIN CSX trial.

Purpose: Cardiac surgery, post-cardiotomy cardiogenic shock (PCCS), and temporary mechanical circulatory support (tMCS) provoke substantial inflammation. We therefore investigated whether a selenium-based, anti-inflammatory strategy would benefit PCCS patients treated with tMCS in a post-hoc analysis of the sustain CSX trial.

Methods: Post-hoc analysis of patients receiving tMCS for PCCS in the Sustain CSX trial, which investigated the effects of high-dose selenium on postoperative organ dysfunction in cardiac surgery patients.

The effect of a selenium-based anti-inflammatory strategy on postoperative functional recovery in high-risk cardiac surgery patients - A nested sub-study of the sustain CSX trial.

Aim: The cardiac surgery-related ischemia-reperfusion-related oxidative stress triggers the release of cytotoxic reactive oxygen and nitrogen species, contributing to organ failure and ultimately influencing patients' short- and long-term outcomes. Selenium is an essential co-factor for various antioxidant enzymes, thereby contributing to the patients' endogenous antioxidant and anti-inflammatory defense mechanisms. Given these selenium's pleiotropic functions, we investigated the effect of a high-dose selenium-based anti-inflammatory perioperative strategy on functional recovery after cardiac surgery.
