Automatic Segmentation of Bone Graft in Maxillary Sinus via Distance Constrained Network Guided by Prior Anatomical Knowledge.

Maxillary Sinus Lifting is a crucial surgical procedure for addressing insufficient alveolar bone mass andsevere resorption in dental implant therapy. To accurately analyze the geometry changesof the bone graft (BG) in the maxillary sinus (MS), it is essential to perform quantitative analysis. However, automated BG segmentation remains a major challenge due to the complex local appearance, including blurred boundaries, lesion interference, implant and artifact interference, and BG exceeding the MS.

Genetic Nurture Effects on Type 2 Diabetes Among Chinese Han Adults: A Family-Based Design.

: Genes and environments were transmitted across generations. Parents' genetics influence the environments of their offspring; these two modes of inheritance can produce a genetic nurture effect, also known as indirect genetic effects. Such indirect effects may partly account for estimated genetic variance in T2D.

Methods: Seven databases were searched.

NURBS curve shape prior-guided multiscale attention network for automatic segmentation of the inferior alveolar nerve.

Accurate segmentation of the inferior alveolar nerve (IAN) within Cone-Beam Computed Tomography (CBCT) images is critical for the precise planning of oral and maxillofacial surgeries, especially to avoid IAN damage. Existing methods often fail due to the low contrast of the IAN and the presence of artifacts, which can cause segmentation discontinuities. To address these challenges, this paper proposes a novel approach that employs Non-Uniform Rational B-Spline (NURBS) curve shape priors into a multiscale attention network for the automatic segmentation of the IAN.

Identification of shared genetic etiology of cardiovascular and cerebrovascular diseases through common cardiometabolic risk factors.

Cardiovascular diseases (CVDs) and cerebrovascular diseases (CeVDs) are closely related vascular diseases, sharing common cardiometabolic risk factors (RFs). Although pleiotropic genetic variants of these two diseases have been reported, their underlying pathological mechanisms are still unclear. Leveraging GWAS summary data and using genetic correlation, pleiotropic variants identification, and colocalization analyses, we identified 11 colocalized loci for CVDs-CeVDs-BP (blood pressure), CVDs-CeVDs-LIP (lipid traits), and CVDs-CeVDs-cIMT (carotid intima-media thickness) triplets.

ZygoPlanner: A three-stage graphics-based framework for optimal preoperative planning of zygomatic implant placement.

Zygomatic implant surgery is an essential treatment option of oral rehabilitation for patients with severe maxillary defect, and preoperative planning is an important approach to enhance the surgical outcomes. However, the current planning still heavily relies on manual interventions, which is labor-intensive, experience-dependent, and poorly reproducible. Therefore, we propose ZygoPlanner, a pioneering efficient preoperative planning framework for zygomatic implantation, which may be the first solution that seamlessly involves the positioning of zygomatic bones, the generation of alternative paths, and the computation of optimal implantation paths.

Objective: This systematic review and meta-analysis aimed to evaluate the diagnostic value of bleeding on probing (BOP) for peri‑implantitis detection on implant- and patient-levels, as reported in prospective and retrospective studies with at least 5 years of follow-up.

Materials And Methods: A systematic search of 3 electronic databases was conducted and supplemented with a hand-search to identify clinical studies that reported the prevalence of peri‑implantitis and BOP after at least 5 years of functional loading. Random-effects meta-analyses were conducted to combine the proportions of peri‑implantitis among BOP positive implants and patients across studies.

Injectable pH-responsive polypeptide hydrogels for local delivery of doxorubicin.

Cancer, as a global health threat, is often treated with chemotherapy, but its effect is limited, especially the drugs such as doxorubicin (DOX) are limited by their non-specificity and side effects. This study focuses on developing a new drug delivery system to overcome these challenges. Based on the self-assembling peptide hemopressin (HP), we designed and screened FOK peptide, which serves as a pH-responsive carrier with excellent pH sensitivity and mechanical stability.

A fully digital planning protocol for dynamic computer-assisted zygomatic implant surgery based on virtual surgery simulation: A dental technique.

Dynamic navigation-guided zygomatic implant (ZI) surgery has been a preferred option for achieving optimal prosthetic-driven implant placement. However, during the actual surgical procedure, surgical execution may still be hindered by environmental factors such as mouth opening. A fully digital planning protocol is described that integrated the patient's maxillofacial soft tissue information and virtual surgical handpiece with the drills on the implant planning path to ensure the precise, time-saving, and smooth implementation of dynamic navigation-guided ZI surgery.
