As an alternative to intracoronary modalities, electron beam computed tomography (EBCT) and multislice spiral computed tomography (MSCT) are able to noninvasively image the coronary arteries. In addition to stenosis detection by imaging the vessel lumen, MSCT has the ability to visualize the coronary artery wall. By using computed tomography (CT), the various components of atherosclerotic plaque may be distinguished and characterized, which holds the promise of, eventually, identifying vulnerable plaque.

Associations of fat, bone, and muscle indices with disease severity in patients with obstructive sleep apnea hypopnea syndrome.
Sleep Breath
January 2025
Department of Pulmonary and Critical Care Medicine, Beijing Hospital, National Center of Gerontology, Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, No.1 Da Hua Road, Dong Dan, Dongcheng District, Beijing, 100730, PR China.
Purpose: To investigate the relationship between obstructive sleep apnea hypopnea syndrome (OSAHS) severity and fat, bone, and muscle indices.
Methods: This study included 102 patients with OSAHS and retrospectively reviewed their physical examination data. All patients underwent polysomnography, body composition analysis, dual-energy X-ray absorptiometry, computed tomography (CT) and blood test.
Influences of patient positioning and general anesthesia on condylar position and surgical accuracy in orthognathic surgery.
Clin Oral Investig
January 2025
Department of Oral and Maxillofacial Surgery, Radboud University Medical Center, Geert Grooteplein 10, Nijmegen, 6525, GA, the Netherlands.
Objectives: To assess the effect of patient positioning and general anesthesia on the condylar position in orthognathic surgery.
Materials And Methods: This prospective study included patients undergoing orthognathic surgery between 2019 and 2020. Four weeks prior to surgery (T0) cone-beam computed tomography (CBCT) scans and intra-oral scans (IOS) were acquired in an upright position.
Reducing Healing Period with DDM/rhBMP-2 Grafting for Early Loading in Dental Implant Surgery.
Tissue Eng Regen Med
January 2025
Department of Oral and Maxillofacial Surgery, Section of Dentistry, Seoul National University Bundang Hospital, 172 Dolma-ro, Bundang-gu, Seongnam-si, Gyeonggi-do, 13620, Republic of Korea.
Background: Traditionally, dental implants require a healing period of 4 to 9 months for osseointegration, with longer recovery times considered when bone grafting is needed. This retrospective study evaluates the clinical efficacy of demineralized dentin matrix (DDM) combined with recombinant human bone morphogenetic protein-2 (rhBMP-2) during dental implant placement to expedite the osseointegration period for early loading.
Methods: Thirty patients (17 male, 13 female; mean age 55.
Coronal Plane Alignment of the Medial Column in Isolated Hallux Valgus, Isolated Flatfoot, and Combined Hallux Valgus-Flatfoot.
Foot Ankle Int
January 2025
Department of Orthopedics and Rehabilitation, Carver College of Medicine, University of Iowa, Iowa City, IA, USA.
Background: To provide improved treatment for hallux valgus (HV), we sought to understand more about the pathophysiologic connection between flatfoot deformity and HV by comparing coronal plane alignment of the medial column of the foot for patients with isolated HV, isolated flatfoot, and combined HV-flatfoot vs controls.
Methods: This study retrospectively assessed a consecutive series of 33 patients with combined symptomatic and radiographic HV and flatfoot, 33 isolated symptomatic HV, 33 isolated symptomatic flatfoot, and 33 controls. The medial column alignment was assessed in the coronal plane using 3-dimensional weightbearing computed tomography (WBCT); rotation was measured for the navicular, medial cuneiform, and first metatarsal (M1).
Muscle Loss During First-Line Chemotherapy Impairs Survival in Advanced Pancreatic Cancer Despite Adapted Physical Activity.
J Cachexia Sarcopenia Muscle
January 2025
Department of Medical Oncology, Lille University Hospital, Lille, France.
Background: Advanced pancreatic ductal adenocarcinoma (aPDAC) is often accompanied by significant muscle mass loss, contributing to poor prognosis. SarcAPACaP, an ancillary study of the GERCOR-APACaP phase III trial, evaluated the role of adapted physical activity (APA) in aPDAC Western patients receiving first-line chemotherapy. The study aimed to assess (1) the potential impact of computed tomography (CT)-quantified muscle mass before and during treatments on health-related quality of life (HRQoL) and overall survival (OS) and (2) the role of APA in mitigating muscle mass loss.
