The implantation of a stent in ostial lesions with Szabo technique is a simple, ingenious and useful way of treating these complex lesions. But in some circumstances the manipulation of the stent added to a calcified vessel could finish with complications. We present a case of stent dislodgement during Szabo technique in an ostial lesion placed in left anterior descending artery.

Aims: It is common in heart failure (HF) trials, especially in HF with preserved (HFpEF) and mildly reduced ejection fraction (HFmrEF), to select for increased risk of outcomes ('enrichment'). We investigated the association between loop diuretic use and common trial outcomes.
Methods And Results: Patients in the Swedish HF Registry with HFmrEF and HFpEF were divided into three groups: no loop diuretic use, 1-40 mg furosemide equivalent, and >40 mg.

Objective: To identify the sonomorphological appearance and to measure the thickness of the piriformis muscle (PM) and the proximal portion of the sacral nerve roots S1-S3 in healthy premenopausal women.
Materials And Methods: This prospective multicentric observational study included a consecutive series of women undergoing transvaginal sonography (TVS) at two tertiary gynecological referral centers. Standardized assessment of the pelvic organs was performed followed by an attempt to visualize the right and left PM and sacral nerve roots S1-S3 at their origin in proximity to the sacral neuroforamen.

Variational ab initio methods in quantum chemistry stand out among other methods in providing direct access to the wave function. This allows, in principle, straightforward extraction of any other observable of interest, besides the energy, but, in practice, this extraction is often technically difficult and computationally impractical. Here, we consider the electron density as a central observable in quantum chemistry and introduce a novel method to obtain accurate densities from real-space many-electron wave functions by representing the density with a neural network that captures known asymptotic properties and is trained from the wave function by score matching and noise-contrastive estimation.

Single-cell RNA sequencing (scRNA-seq) is invaluable for profiling cellular heterogeneity and transcriptional states, but transcriptomic profiles do not always delineate subsets defined by surface proteins. Cellular indexing of transcriptomes and epitopes (CITE-seq) enables simultaneous profiling of single-cell transcriptomes and surface proteomes; however, accurate cell-type annotation requires a classifier that integrates multimodal data. Here, we describe multimodal classifier hierarchy (MMoCHi), a marker-based approach for accurate cell-type classification across multiple single-cell modalities that does not rely on reference atlases.

Purpose Of Review: To evaluate existing functional magnetic resonance imaging (fMRI) studies on post-traumatic headache (PTH) following traumatic brain injury (TBI).
Recent Findings: We conducted a systematic search of PubMed and Embase databases from inception to February 1, 2024. Eligible fMRI studies were required to include adult participants diagnosed with acute or persistent PTH post-TBI in accordance with any edition of the International Classification of Headache Disorders.
