Objective: The aim of this report is to present the workflow of a surgical procedure involving U-shaped splitting in an envelope flap with simultaneous implant placement using two digital guides for patients with insufficient bone width and labial concavity.
Clinical Consideration: Two digital guides and an envelope flap are proposed in this report. An implant drilling guide and an osteotomy guide guarantee the precise execution of surgical procedures. Using an envelope flap enhances the integrity of the labial mucoperiosteum, minimizing surgical trauma and improving the effect of bone augmentation.
Conclusion: With the assistance of two digital guides, precise U-shaped splitting in an envelope flap can minimize surgical trauma and have a significant effect on horizontal bone augmentation.
Clinical Significance: This workflow considers the implant positions, the scope of osteotomy, and the kind of flap. It ensures minimal surgical trauma and excellent bone augmentation effect, which means predictable esthetic outcomes and stability in oral implantology, and provides a considerable solution for patients with insufficient bone width and labial concavity.

Background: X-ray grating-based dark-field imaging can sense the small angle scattering caused by object's micro-structures. This technique is sensitive to the porous microstructure of lung alveoli and has the potential to detect lung diseases at an early stage. Up to now, a human-scale dark-field CT (DF-CT) prototype has been built for lung imaging.

Introduction: The escalating resistance of microorganisms to antimicrobials poses a significant public health threat. Strategies that use biomarkers to guide antimicrobial therapy-most notably Procalcitonin (PCT) and C-reactive protein (CRP)-show promise in safely reducing patient antibiotic exposure. While CRP is less studied, it offers advantages such as lower cost and broader availability compared with PCT.

Purpose: To investigate the prognostic value of post-chemoradiotherapy 2-[F]FDG PET/CT in locally advanced nasopharyngeal carcinoma (LANPC) and develop an accurate prognostic model based on the 2-[F]FDG PET/CT results.
Methods: 900 LANPC patients who underwent pretreatment and post-chemoradiotherapy 2-[F]FDG PET/CT from May 2014 to August 2022 were included in the study. We divided the patients into two distinct cohorts for the purpose of our study: a training cohort comprising 506 individuals, included from May 2008 to April 2020, and a validation cohort consisting of 394 individuals, included from May 2020 to August 2022.

Introduction: While cognitive behavioral therapy (CBT) remains a highly effective psychotherapy approach for managing Alcohol Use Disorder (AUD), its potential is hindered by workforce shortages and access barriers. In response to these challenges, Internet-Based Cognitive Behavioral Therapy (iCBT) has emerged as an innovative solution that integrates the core CBT structure with technology. In iCBT, educational materials, therapist communication and progress dashboards can be centralized in a digital format, and delivered in a self-guided, therapist-guided or blended approach.

Importance: Condoms are effective at preventing sexually transmitted infections and pregnancy; however, only 52% of sexually active US adolescents used a condom at last intercourse.
Objective: To examine (1) the association between 36 psychosocial variables and adolescent condom use to determine the strongest correlates of condom use behavior across the literature, (2) heterogeneity of these effects, and (3) the moderating roles of age, gender/sex, race/ethnicity, sexual orientation, and year of study.
Data Sources: A systematic search was conducted of studies published between January 2000 and February 2024 using Medline, CINAHL, PsycINFO, and Communication Source databases, plus relevant review articles and unpublished data.
