Objectives: A core outcome set (COS) giving indicators of the quality of the process for minimally invasive valve surgery embedded into Enhanced Recovery After Surgery (ERAS) protocols should be developed.

Methods: Using web-based questionnaires, a Delphi process with three rounds was conducted from January to December 2022. Prior to the rounds, a systematic database search was performed identifying potential quality parameters.

Despite advancements in antiretroviral therapy (ART) that reduces the viral load to undetectable levels and improve CD4 T cell counts, viral eradication has not been achieved due to HIV-1 persistence in resting CD4 T-cells. We, therefore, characterized the gene, which is essential for HIV-1 replication and pathogenesis, from 20 virologically controlled aging individuals with HIV (HIV) on long-term ART and improved CD4 T-cell counts, with a particular focus on older individuals. Peripheral blood mononuclear cell genomic DNA from HIV were used to amplify gene by polymerase chain reaction followed by nucleotide sequencing and analysis.

Hydrogen hydrates exhibit a rich phase diagram influenced by both pressure and temperature, with the so-called C_{2} phase emerging prominently above 2.5 GPa. In this phase, hydrogen molecules are densely packed within a cubic icelike lattice and the interaction with the surrounding water molecules profoundly affects their quantum rotational dynamics.

Long coronavirus disease 2019 (COVID) (LC) symptoms including pain and autonomic dysfunction are in some patients associated with small-fiber neuropathy (SFN). The pathomechanisms underlying SFN are mostly unclear. Natural killer (NK) cells play a crucial role in immune regulation, viral clearance and nerve metabolism.

Introduction: With the advent of disease-modifying therapies, accurate assessment of biomarkers indicating the presence of disease-associated amyloid beta (Aβ) pathology becomes crucial in patients with clinically suspected Alzheimer's disease (AD). We evaluated Aβ levels in cerebrospinal fluid (Aβ CSF) and Aβ levels in positron emission tomography (Aβ PET) biomarkers in a real-world memory-clinic setting to develop an efficient algorithm for clinical use.

Methods: Patients were evaluated for AD-related Aβ pathology from two independent cohorts (Ludwig Maximilian University [LMU],  = 402, and Medical University of Vienna [MUV],  = 144).
