Objective: To assess soft tissues in the short and long term after bimaxillary surgery in Class III patients by comparing the hard tissue changes and results between time periods.
Materials And Methods: Twenty-six Class III adult patients treated with bimaxillary surgery were included in the study. Cephalometric records were taken before surgery (T1) and 5 months (T2), 1.4 years (T3), 3 years (T4), and 5 years (T5) after surgery.
Results: There was no significant relapse in skeletal parameters. Overjet was significantly reduced between T4-T3 time intervals (P < .01). There were significant increases in Sn-HR, ULA-HR, LLA-HR, B-B(∧) (P < .01), and B(∧)-HR (P < .05) between T4-T3 time intervals. There was no significant change in the soft tissue parameters between T5-T4 time intervals.
Conclusion: Soft tissue vertical relapse occurs in skeletally stabile Class III bimaxillary surgery patients in the first 3 years after surgery.

Cephalometric analysis is the primary diagnosis method in orthodontics. In our previous study, the algorithm was developed to estimate cephalometric landmarks from lateral facial photographs of patients with normal occlusion. This study evaluates the estimation accuracy by the algorithm trained on a dataset of 2320 patients with added malocclusion patients and the analysis values.

Introduction: The primary objective of this study was to assess the 3-dimensional position of the mandibular canal (MC) in different craniofacial patterns to know about the safe placement of temporary skeletal anchorage devices using cone-beam computed tomography (CBCT). The secondary objectives were to assess sex differences and correlate the MC position with various factors.
Methods: This prospective, observational study was conducted on 90 patients, divided into 3 groups based on the sagittal pattern: skeletal Class I, Class II, and Class III.
HLA Class I and II Alleles in Anti-Acetylcholine Receptor Antibodies Positive and Double-Seronegative Myasthenia Gravis Patients of Romanian Descent.

: Several significant associations between certain Human Leukocyte Antigen (HLA) alleles and myasthenia gravis (MG) subtypes were established in populations from Western Europe and North America and, to a lesser extent, from China and Japan. However, such data are scarcely available for Eastern Europe. This study aimed to analyze the associations of HLA Class I and II alleles with MG and its serological subtypes (with anti-acetylcholine receptor autoantibodies, RAch+MG, and double-seronegative, dSNMG) in myasthenic patients of Romanian descent.

Elderly patients with severe aortic stenosis (AS) need individualized decision-making in their management in order to benefit in terms of survival and improvement of quality of life. Frailty, a common condition in elderly patients, needs to be considered when weighing treatment options. We aimed to evaluate outcomes including survival and functional parameters according to disability criteria at six years of follow-up in an older population treated for severe AS using a frailty-based management.

Background: Major adverse cardiovascular events (MACEs) may contribute to the high morbidity in people with four-class drug-resistant HIV (4DR-PWH).
Objectives: To explore the probability of MACEs in 4DR-PWH compared with non-4DR controls.
Methods: This was a retrospective, propensity score-matched cohort study on 4DR-PWH (cases) and non-4DR-PWH (controls), on ART, without previous MACEs.
