Adjusting for informative cluster size in pseudo-value based regression approaches with clustered time to event data [PDF]

arXiv, 2022
Informative cluster size (ICS) arises in situations with clustered data where a latent relationship exists between the number of participants in a cluster and the outcome measures. Although this phenomenon has been sporadically reported in statistical literature for nearly two decades now, further exploration is needed in certain statistical ...

Epithelial PD‐L1 expression at tumor front predicts overall survival in a cohort of oral squamous cell carcinomas from Sudan

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1467-1477, December 2022., 2022
Abstract Background We recently described the tumor immune microenvironment (TIME) in oral squamous cell carcinomas (OSCC) from Sudan by assessing the core of the lesions. However, the invasive tumor front (ITF) is the most active part of OSCC lesions; thus, TIME should also be characterized at the ITF in this patient cohort.

Automated Process Incorporating Machine Learning Segmentation and Correlation of Oral Diseases with Systemic Health [PDF]

arXiv, 2018
Imaging fluorescent disease biomarkers in tissues and skin is a non-invasive method to screen for health conditions. We report an automated process that combines intraoral fluorescent porphyrin biomarker imaging, clinical examinations and machine learning for correlation of systemic health conditions with periodontal disease. 1215 intraoral fluorescent

Use of the Deep Learning Approach to Measure Alveolar Bone Level [PDF]

arXiv, 2021
Abstract: Aim: The goal was to use a Deep Convolutional Neural Network to measure the radiographic alveolar bone level to aid periodontal diagnosis. Material and methods: A Deep Learning (DL) model was developed by integrating three segmentation networks (bone area, tooth, cementoenamel junction) and image analysis to measure the radiographic bone ...

Evaluation of P53 protein expression in gingival tissues of patients with chronic periodontitis by immunohistochemistry methods

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1348-1353, December 2022., 2022
Abstract Objective Periodontitis is one of the most important periodontal diseases that can be affected by many factors. Although the mechanism of periodontitis development is not yet fully understood, previous studies suggest that apoptosis may be one of the pathological factors that can affect the process of the disease by destroying old and damaged ...

Periodontal Pathogens as Risk Factors of Cardiovascular Diseases, Diabetes, Rheumatoid Arthritis, Cancer, and Chronic Obstructive Pulmonary Disease—Is There Cause for Consideration?

Microorganisms, 2019
Cardiovascular diseases, chronic obstructive pulmonary diseases, diabetes, rheumatoid arthritis, and cancer are the most common noncommunicable diseases (NCDs). These NCDs share risk factors with periodontal disease (PD), a preventable risk factor linked

Factors Associated With Anxiety Symptoms in Older Adults Attending an Outpatient Geriatric Service: A Cross‐Sectional Study

AGING MEDICINE, EarlyView.
An analytical study was carried out by secondary analysis of a database of a study performed between 2010 and 2015 at the Naval Medical Center of Peru (CEMENA). the analysis revealed that depressive symptoms, polypharmacy, slow gait speed, education, and marital status were significant contributors to anxiety in this population.
