Severity of Pediatric Inflammatory Multisystem Syndrome Temporally Associated with SARS-CoV-2 Diminished During Successive Waves of the COVID-19 Pandemic: Data from a Nationwide German Survey.

Objective: To elucidate how the clinical presentation of Pediatric Inflammatory Multisystem Syndrome temporally associated with Severe Acute Respiratory Syndrome-related Coronavirus 2 (PIMS-TS) was influenced by the successive variants of concern (VOC) and patient age.

Study Design: A nationwide PIMS-TS registry was established in Germany in May 2020, shortly after the first cases were described in the US and United Kingdom. The registry captured information on patient characteristics, clinical course, laboratory findings, imaging, and outcome.

Epigenetic training of human bronchial epithelium cells by repeated rhinovirus infections.

Background: Humans are subjected to various environmental stressors (bacteria, viruses, pollution) throughout life. As such, an inherent relationship exists between the effect of these exposures with age. The impact of these environmental stressors can manifest through DNA methylation (DNAm).

The Three Powerful Traditions of Thinking that Constitute Homeopathy.

By means of a historical, classical philological and philosophical approach, this paper attempts to demonstrate that homeopathy is based on three powerful traditions of thinking, which can be traced back to Ancient Greece's pre-Socratic era. Actually, it seems to be constituted by what may be termed -, - and -thinking: that is, thinking in terms of rationality, similarity and healing. By contrast, modern medicine tends to be aligned with just one of these traditions, at the expense of the others, this being not without risk and adverse effects.

Predictors for major in-hospital complications after catheter ablation of ventricular arrhythmias: validation and modification of the Risk in Ventricular Ablation (RIVA) Score.

Objective And Background: Catheter-based treatment of patients with ventricular arrhythmias (VA) reduces VA and mortality in selected patients. With regard to potential risks of catheter ablation, a benefit-risk assessment should be carried out. This can be performed with risk scores such as the recently published "Risk in Ventricular Ablation (RIVA) Score".

Integrating Mechanisms in Thrombotic Peripheral Arterial Disease.

Peripheral arterial disease (PAD), a manifestation of systemic atherosclerosis, is underdiagnosed in the general population. Despite the extensive research performed to unravel its pathophysiology, inadequate knowledge exists, thus preventing the development of new treatments. This review aims to highlight the essential elements of atherosclerosis contributing to the pathophysiology of PAD.

neutrophil migration is associated with inhaled corticosteroid treatment and serum cytokines in pediatric asthma.

Different asthma phenotypes are driven by molecular endotypes. A Th1-high phenotype is linked to severe, therapy-refractory asthma, subclinical infections and neutrophil inflammation. Previously, we found neutrophil granulocytes (NGs) from asthmatics exhibit decreased chemotaxis towards leukotriene B4 (LTB), a chemoattractant involved in inflammation response.

Combining BeEAM with Brentuximab Vedotin for High-Dose Therapy in CD30 Positive Lymphomas before Autologous Transplantation-A Phase I Study.

The prognosis for patients with CD30+ lymphomas (Hodgkin lymphoma and various T-cell lymphomas) relapsing after autologous stem cell transplantation (ASCT) is critical. Brentuximab vedotin (BV), an ADC targeting CD30, is an obvious candidate for inclusion into high-dose chemotherapy (HDCT) regimens to improve outcomes. This single center phase I trial investigated 12 patients with CD30+ lymphoma (AITL: = 5; relapsed HL: = 7; median of two previous treatment lines) undergoing ASCT.

Effect of Sirolimus vs. Everolimus on CMV-Infections after Kidney Transplantation-A Network Meta-Analysis.

(1) Background: Following renal transplantation, infection with cytomegalovirus (CMV) is a common and feared complication. mTOR-inhibitor (mTOR-I) treatment, either alone or in combination with calcineurininhibitors (CNIs), significantly reduces the CMV incidence after organ transplantation. As of now, there is no information on which mTOR-I, sirolimus (SIR) or everolimus (ERL), has a stronger anti-CMV effect.

Myeloid CD40 deficiency reduces atherosclerosis by impairing macrophages' transition into a pro-inflammatory state.

Aims: CD40 and its ligand, CD40L, play a critical role in driving atherosclerotic plaque development. Disrupted CD40-signalling reduces experimental atherosclerosis and induces a favourable stable plaque phenotype. We recently showed that small molecule-based inhibition of CD40-tumour necrosis factor receptor associated factor-6 interactions attenuates atherosclerosis in hyperlipidaemic mice via macrophage-driven mechanisms.

Immuno-PET Imaging of Atherosclerotic Plaques with [Zr]Zr-Anti-CD40 mAb-Proof of Concept.

Non-invasive imaging of atherosclerosis can help in the identification of vulnerable plaque lesions. CD40 is a co-stimulatory molecule present on various immune and non-immune cells in the plaques and is linked to inflammation and plaque instability. We hypothesize that a Zr-labeled anti-CD40 monoclonal antibody (mAb) tracer has the potential to bind to cells present in atherosclerotic lesions and that CD40 Positron Emission Tomography (PET) can contribute to the detection of vulnerable atherosclerotic plaque lesions.

International Survey of Clinical Monitoring Practices in Pancreas and Islet Transplantation.

Background: The long-term outcomes of both pancreas and islet allotransplantation have been compromised by difficulties in the detection of early graft dysfunction at a time when a clinical intervention can prevent further deterioration and preserve allograft function. The lack of standardized strategies for monitoring pancreas and islet allograft function prompted an international survey established by an International Pancreas and Islet Transplant Association/European Pancreas and Islet Transplant Association working group.

Methods: A global survey was administered to 24 pancreas and 18 islet programs using Redcap.

Many heads are more utilitarian than one.

Moral judgments have a very prominent social nature, and in everyday life, they are continually shaped by discussions with others. Psychological investigations of these judgments, however, have rarely addressed the impact of social interactions. To examine the role of social interaction on moral judgments within small groups, we had groups of 4 to 5 participants judge moral dilemmas first individually and privately, then collectively and interactively, and finally individually a second time.

Large-scale cis- and trans-eQTL analyses identify thousands of genetic loci and polygenic scores that regulate blood gene expression.

Trait-associated genetic variants affect complex phenotypes primarily via regulatory mechanisms on the transcriptome. To investigate the genetics of gene expression, we performed cis- and trans-expression quantitative trait locus (eQTL) analyses using blood-derived expression from 31,684 individuals through the eQTLGen Consortium. We detected cis-eQTL for 88% of genes, and these were replicable in numerous tissues.

COL4A3 is degraded in allergic asthma and degradation predicts response to anti-IgE therapy.

Background: Asthma is a heterogeneous syndrome substantiating the urgent requirement for endotype-specific biomarkers. Dysbalance of fibrosis and fibrolysis in asthmatic lung tissue leads to reduced levels of the inflammation-protective collagen 4 (COL4A3).

Objective: To delineate the degradation of COL4A3 in allergic airway inflammation and evaluate the resultant product as a biomarker for anti-IgE therapy response.

Neu3 neuraminidase induction triggers intestinal inflammation and colitis in a model of recurrent human food-poisoning.

Intestinal inflammation is the underlying basis of colitis and the inflammatory bowel diseases. These syndromes originate from genetic and environmental factors that remain to be fully identified. Infections are possible disease triggers, including recurrent human food-poisoning by the common foodborne pathogen Typhimurium (), which in laboratory mice causes progressive intestinal inflammation leading to an enduring colitis.

Immune checkpoint inhibitor treatment and atherosclerotic cardiovascular disease: an emerging clinical problem.

Antibody-mediated blockade of co-inhibitory molecules such as cytotoxic T lymphocyte-associated protein 4, PD1 and PDL1 elicits potent antitumor responses and improves the prognosis of many patients with cancer. As these immune checkpoint inhibitors (ICIs) are increasingly prescribed to a diverse patient population, a broad range of adverse effects is emerging. Atherosclerosis, a lipid-driven chronic inflammatory disease of the large arteries, may be aggravated by ICI treatment.

Gamma-gliadin specific celiac disease antibodies recognize p31-43 and p57-68 alpha gliadin peptides in deamidation related manner as a result of cross-reaction.

Celiac disease (CeD) is a T-cell-dependent enteropathy with autoimmune features where tissue transglutaminase (TG2)-mediated posttranslational modification of gliadin peptides has a decisive role in the pathomechanism. The humoral immune response is reported to target mainly TG2-deamidated γ-gliadin peptides. However, α-gliadin peptides, like p57-68, playing a crucial role in the T-cell response, and p31-43, a major trigger of innate responses, also contain B-cell gliadin epitopes and γ-gliadin like motifs.

Similia Similibus Curentur: Theory, History, and Status of the Constitutive Principle of Homeopathy.

A clear definition of its subject and correct application of its tenets are the basis of any science. Conversely, the want of a unanimous understanding of its constituting principles by the homeopathic community is undermining its scientific practice, research and discussion. To facilitate these, first and foremost the Principle of Similars, , has to be clarified and assessed in terms of its theoretical meaning, historical development, and epistemological status.

Only Hyperuricemia with Crystalluria, but not Asymptomatic Hyperuricemia, Drives Progression of Chronic Kidney Disease.

Background: The roles of asymptomatic hyperuricemia or uric acid (UA) crystals in CKD progression are unknown. Hypotheses to explain links between UA deposition and progression of CKD include that () asymptomatic hyperuricemia does not promote CKD progression unless UA crystallizes in the kidney; () UA crystal granulomas may form due to pre-existing CKD; and () proinflammatory granuloma-related M1-like macrophages may drive UA crystal-induced CKD progression.

Methods: MALDI-FTICR mass spectrometry, immunohistochemistry, 3D confocal microscopy, and flow cytometry were used to characterize a novel mouse model of hyperuricemia and chronic UA crystal nephropathy with granulomatous nephritis.

The Need for Multidisciplinary Research within the History and Theory of Homeopathy.

The controversial issue of homeopathy's scientificity will, in all probability, not be settled by means of clinical trials alone, as long as uncertainty or ignorance about methodological, philosophical, and socio-economical essentials prevail on both sides of the argument. Rather than uncritically adopt the standards of the currently predominant paradigm, homeopathy should not forget its roots, peculiarities, and self-conception. Contrary to conventional medicine, it is based on a teleological image of humanity, a holistic and sustainable approach towards curing sickness, and an up-to-date concept of medical theory in terms of healing arts.

Antibody-Mediated Inhibition of CTLA4 Aggravates Atherosclerotic Plaque Inflammation and Progression in Hyperlipidemic Mice.

T cell-driven inflammation plays a critical role in the initiation and progression of atherosclerosis. The co-inhibitory protein Cytotoxic T-Lymphocyte Associated protein (CTLA) 4 is an important negative regulator of T cell activation. Here, we studied the effects of the antibody-mediated inhibition of CTLA4 on experimental atherosclerosis by treating 6-8-week-old Ldlr mice, fed a 0.
