Establishment and clinical impacts of decision-support system for older patients with aortic valve stenosis: A retrospective observational study.

Objectives: Treatment decisions for severe aortic stenosis (AS) are complex, since there are two active and comparable options: transcatheter aortic valve implantation and surgical aortic valve replacement. The disease predominantly affects older individuals, who are frequently comorbid with from cognitive impairment. This study aimed to establish a screening-triggered system to assess the decision-making capacity of patients with AS, support their decision-making, and facilitate referrals to specialists when necessary.

A 25-year clonal resurrection in adult T-cell leukemia-lymphoma relapse.

Here, we report a rare case of relapsed adult T-cell leukemia-lymphoma (ATL) with evidence of clonal relapse 26 years after initial diagnosis. The patient had been diagnosed with an aggressive form of lymphoma-type ATL 26 years prior and did not receive further ATL treatment for approximately 26 years after achieving complete remission. We used nested PCR to identify the amplification of ATL clone-specific accumulation sites in DNA from hematoxylin and eosin-stained specimens from the patient.

Simultaneous bilateral total hip arthroplasty results in smaller Leg length discrepancy than staged bilateral procedures.

Introduction: The purpose of this study was to compare leg length discrepancies (LLD) between simultaneous and staged bilateral total hip arthroplasty (BTHA).

Materials And Methods: This retrospective cohort study included 150 consecutive patients who underwent BTHA (60 simultaneous and 90 staged BTHA). To adjust for preoperative patient characteristics between groups, 1:1 propensity score matching was performed based on age, sex, body mass index, American Society of Anesthesiologists Physical Status, Tönnis classification, Crowe classification, preoperative range of motion (flexion and abduction), LLD, and Harris Hip Score (HHS).

Neuronal substance P-driven MRGPRX2-dependent mast cell degranulation products differentially promote vascular permeability.

Mas-related G protein-coupled receptor b2 (Mrgprb2) binding to its cationic endogenous and exogenous ligands induces mast cell degranulation and promotes inflammation in mice. However, the physiological roles of its human homologue MRGPRX2 remain unclear. Here we aimed to elucidate the mechanisms by which MRGPRX2 regulates vascular permeability, and generated MRGPRX2 knock-in (MRGPRX2-KI) and Mrgprb2 knockout (Mrgprb2-KO) mice.

Clinical significance of NOTCH1 and FBXW7 alterations in adult T-cell leukemia/lymphoma.

Here, we investigated the clinical significance of NOTCH1 and FBXW7 alterations for adult T-cell leukemia/lymphoma (ATLL) treatment outcomes. NOTCH1 alterations were identified in 37 (14.4%) of 257 patients, of which 33 were single nucleotide variants/insertion-deletions in the PEST domain, and 7 were in the heterodimerization or LIN-12/Notch repeats domains.
