Purpose: This study aimed to investigate frontal sinus volume as a potential indicator of cranial compensatory growth in unoperated normocephalic nonsyndromic sagittal craniosynostosis (NNSC) patients compared with age-matched and sex-matched controls. Previous studies have suggested that frontal sinus volume is suppressed in unoperated craniosynostosis and may be an intracranial space conservation phenomenon.
Methods: Head computed tomographies (CTs) from 22 unoperated NNSC patients at our institution were utilized in this study and matched with age-matched and sex-matched control subjects.

It is unknown whether this applies to patients with low-risk disease following simple hysterectomy.
Methods: Among patients who underwent simple hysterectomy in the Simple Hysterectomy And PElvic node assessment trial, univariate and multivariate Cox models were used to assess the association of minimally invasive versus open surgery with clinical outcomes, including pelvic and extra-pelvic recurrence-free survival, overall recurrence-free survival, and overall survival.

Background: While recent randomized controlled trials have demonstrated that sublobar resection is non-inferior to lobectomy, the comparative efficacy of these procedures remains uncertain for early-stage non-small cell lung cancer (NSCLC; ≤ 3 cm) exhibiting invasive features postoperatively, such as visceral pleural invasion (VPI) or spread through air spaces (STAS).
Materials And Methods: To identify eligible studies, a comprehensive search of PubMed, Embase, MEDLINE, the Cochrane Library, and Web of Science was conducted through 25 July 2024. Studies were screened according to predefined criteria in accordance with PRISMA guidelines.

Mixture Markov Model (MMM) is a widely used tool to cluster sequences of events coming from a finite state-space. However, the MMM likelihood being multi-modal, the challenge remains in its maximization. Although Expectation-Maximization (EM) algorithm remains one of the most popular ways to estimate the MMM parameters, however, convergence of EM algorithm is not always guaranteed.
