Article Synopsis
- The study investigates CP symmetry violation in the decay of D^{+} particles into K^{-}K^{+}π^{+} using data from proton-proton collisions at a high energy of 13 TeV.
- A unique model-independent method was employed to analyze the phase-space distributions of D^{+} and D^{-} particles, correcting for any instrumental biases using D_{s}^{+} decays.
- The findings indicate no significant evidence of CP violation, with a p value of 8.1%, and measure specific CP asymmetry observables, marking this study as the most sensitive search of its kind in multibody decays.
Purpose: This study investigates the relationship between surgical levels and coronal deformity to identify risk factors for failing to achieve a minimal clinically important difference (MCID) in the Oswestry Disability Index (ODI) following short-segment isolated decompression or fusion surgery in patients with degenerative scoliosis (DS) and concurrent lumbar canal stenosis (LCS), without severe sagittal deformity malalignment.
Methods: Patients with degenerative scoliosis who underwent 1- or 2-level lumbar isolated decompression or fusion surgery were included. Surgical level was labeled as "Cobb-related" when decompression or surgical levels spanned or were between end vertebrae, and "outside" when the operative levels did not include the end vertebrae.
Immunocompromised patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can have a longer duration of viral shedding and persistence of symptoms. The optimal treatment strategy for these patients remains to be established. This case describes a male in his late sixties with follicular lymphoma and persistent symptoms of infection with SARS-CoV-2 variant BA.

While Gfral-expressing cells are known to be present in the area postrema and nucleus of the solitary tract (AP/NTS) located in the brainstem, the presence of Gfral-expressing cells in other sites within the central nervous system and peripheral tissues is not been fully addressed. Our objective was to thoroughly investigate whether GFRAL is expressed in peripheral tissues and in brain sites different from the brainstem.

- The study was a retrospective cohort review comparing single level (SLD) and dual level (DLD) minimally invasive decompression surgeries for lumbar spinal stenosis (LSS) in patients with adjacent level disease.
- Findings indicated that patients undergoing single level decompression experienced similar clinical outcomes to those with dual level decompression over a 2-year period, despite longer operative times for DLD procedures.
- The conclusion suggests that for patients with single level symptoms and adjacent stenosis, treating only the symptomatic level is equally effective, potentially reducing unnecessary risks and surgery time associated with dual level procedures.
