[Pneumonia due to silent aspiration: a diagnostic and therapeutic challenge].

Aspiration pneumonia (AP) may present as gross aspiration of large gastric contents or as a consequence of silent aspiration of contaminated oropharyngeal secretions.AP due to silent aspiration is caused by dysphagia and, in some instances, impaired cough reflex. Factors favouring the development of pneumonia include advanced age as well as severe comorbidity and impaired functional status.

A high-dimensional neural network potential for CoO.

The CoOspinel is an important material in oxidation catalysis. Its properties under catalytic conditions, i.e.

A terpyridine-based copper complex for electrochemical reduction of nitrite to nitric oxide.

In biological systems, nitrite reductase enzymes (NIRs) are responsible for reduction of nitrite (NO) to nitric oxide (NO). These NIRs have mostly Cu- or Fe-containing active sites, surrounded by amine-containing ligands. Therefore, mononuclear Cu complexes with N-donor ligands are highly relevant in the development of NIR model systems and in the mechanistic investigation of the nitrite reduction reaction.

[Criteria for the authorization of training in medical specialist competence in internal medicine and rheumatology-A position paper of the German Society for Rheumatology and Clinical Immunology].

The model advanced training regulations define the content of advanced training to achieve the qualification of medical specialist in internal medicine and rheumatology. There are currently no criteria for issuing the authorization in advanced training. This position paper describes the criteria proposed by the German Society for Rheumatology and Clinical Immunology (DGRh), which should be the foundation for the issuance of authorization for advanced training in the field of internal medicine and rheumatology and for the assessment of the duration.

Management of acute decompensated valvular heart disease.

Worldwide, valvular heart disease (VHD) is a common cause of hospitalization for acute heart failure. In acute heart failure caused by VHD, symptoms result from rapid haemodynamic changes and subsequent decline in cardiac function, and if left untreated, leads to acute decompensation and cardiogenic shock. Current evidence remains scarce and recommendations regarding the management of acute heart failure caused by VHD are lacking in most recent international guidelines.

The influence of lipoprotein(a) on aortic valve calcification in patients undergoing transcatheter aortic valve replacement.

Background: Elevated levels of lipoprotein(a) (Lp[a]) have been recognized as substantial risk factors for cardiovascular disease and aortic stenosis (AS). However, the specific role of Lp(a) in promoting aortic valve calcification (AVC) and influencing mortality in elderly, multimorbid patients undergoing transcatheter aortic valve replacement (TAVR) remains unclear and warrants further investigation.

Methods: A retrospective analysis was conducted on all consecutive patients who underwent TAVR between August 2019 and June 2020 at our clinic.

Impact of body mass index on an initial minimally invasive aortic valve program.

Background: In obese patients, minimally invasive aortic valve replacement (MIS-AVR) presents challenges, and the risk of patient-prosthesis mismatch (PPM) is elevated. This retrospective single-center study evaluates the impact of body mass index (BMI) on the outcome of an initial MIS-AVR program.

Material And Methods: 307 patients underwent MIS-AVR between 01/2013-12/2015, the initial phase of our MIS-AVR program.

Ion Effects on Terahertz Spectra of Microsolvated Clusters.

Water clusters containing Na and Cl ions play a key role in the atmospheric chemistry of sea salt aerosols. While Na is clearly buried deep inside, Cl appears to be a chameleon since evidence for both surface-localized and interior solvation states are reported. Thus, disclosing the preferred location of Cl within clusters remains challenging.

[Influence of the treatment setting on the treatment of patients with rheumatoid arthritis or psoriatic arthritis within the delegation to rheumatological specialist assistants - A post hoc analysis of the StärkeR study].

Background: The StärkeR study has shown the non-inferiority of a team-based form of care with delegation to rheumatological specialist assistants (RFA) compared to standard care in patients with rheumatoid arthritis (RA) or psoriatic arthritis (PsA).

Objective: Exploratory analyses regarding a possible influence of the treatment setting (specialist practice/outpatient clinic) on various outcome parameters in patients with RA or PsA in the context of delegation to RFA.

Material And Methods: Patients with RA or PsA and stable adjustment with low disease activity from 3 outpatient clinics and 14 rheumatological specialist practices that participated in the StärkeR study were included in this post hoc analysis.

Structure, and Phase Transformations of HPM-3: A Layered Precursor of the Neutral Aluminophosphate with Topology.

The structure of HPM-3, a layered aluminophosphate prepared using 1,2,3-trimethylimidazolium (123TMI) as an organic structure-directing agent by the fluoride route, has been solved by continuous rotation electron diffraction (cRED), and Rietveld refined against synchrotron powder X-ray diffraction data. Charge balance of the occluded cation is achieved through F anions and dangling Al(OP)OH groups. Half of the Al is pentacoordinated in negatively charged Al(OP)-F-Al(OP) pairs.

Emotional regulation as a mediating variable between risk of psychosis and common mental health problems in adolescents.

The main clinical high-risk of psychosis (CHRp) approaches are focused on core features of schizophrenia that might surface in the prodromal phases, mainly psychotic-like experiences (PLEs) (e.g., prodromal or schizotypal symptoms) or associated phenomena like basic symptoms or anomalous experiences of the self.

Hydride-Induced Reconstruction of Pd Electrode Surfaces: A Combined Computational and Experimental Study.

Designing electrocatalysts with optimal activity and selectivity relies on a thorough understanding of the surface structure under reaction conditions. In this study, experimental and computational approaches are combined to elucidate reconstruction processes on low-index Pd surfaces during H-insertion following proton electroreduction. While electrochemical scanning tunneling microscopy clearly reveals pronounced surface roughening and morphological changes on Pd(111), Pd(110), and Pd(100) surfaces during cyclic voltammetry, a complementary analysis using inductively coupled plasma mass spectrometry excludes Pd dissolution as the primary cause of the observed restructuring.

Organophotocatalytic Reduction of Benzenes to Cyclohexenes.

The reduction of abundant benzene rings to scarce C(sp)-rich motifs is invaluable for drug design, as C(sp) content is known to correlate with clinical success. Cyclohexenes are attractive targets, as they can be rapidly elaborated into large product libraries and are stable against rearomatization. However, partial reduction reactions of benzenes to cyclohexenes are rare and have a very narrow scope.

[Left bundle branch (area) pacing: lead positioning and implant criteria-step for step].

Left bundle branch area pacing is currently the most common form of physiological pacing prior to His bundle pacing. It is intended to prevent or correct the development of pacemaker-induced cardiomyopathy and is being used more and more frequently. In order to be able to perform this successfully, knowledge regarding the specific anatomy and radiological anatomy as well as the ECG criteria for left bundle branch pacing is required in addition to knowledge of the tools.

Accelerating ab initio melting property calculations with machine learning: application to the high entropy alloy TaVCrW.

Melting properties are critical for designing novel materials, especially for discovering high-performance, high-melting refractory materials. Experimental measurements of these properties are extremely challenging due to their high melting temperatures. Complementary theoretical predictions are, therefore, indispensable.

Identification of a machine learning-based diagnostic model for axial spondyloarthritis in rheumatological routine care using a random forest approach.

Objectives: In axial spondyloarthritis (axSpA), early diagnosis is crucial, but diagnostic delay remains long and diagnostic criteria do not exist. We aimed to identify a diagnostic model that distinguishes patients with axSpA from patients without axSpA with chronic back pain based on clinical data in routine care.

Methods: Clinical data from patients with chronic back pain were used, with information on rheumatological examinations based on clinical indications.
