Exploring the association between smartphone-based place visitation data and neighborhood-level coronary heart disease in the United States.

Coronary Heart Disease (CHD) is the leading cause of death in the United States, affecting over 20.5 million adults. Previous studies link health behaviors - such as dietary behavior, physical activity, smoking, and alcohol consumption - to CHD risk.

Impacts of Residential Segregation and Comorbidity on Racial Disparities in Acute Care Utilization.

Purpose: To examine whether living in highly segregated communities or having comorbidity is associated with an increased risk of acute use of emergency and inpatient services (i.e., acute care utilization [ACU]) among racial minorities.

Ideal Horizontal X-Ray Beam Angulation for Maxillary Molars. A Retrospective Clinical Study Using Cone-Beam Computed Tomography.

The aim of this study was to analyse cone-beam computed tomography (CBCT) images to determine the ideal horizontal X-ray beam angulations for maxillary first and second molars. CBCT scans from 85 patients were retrospectively analysed to measure the angles at which buccal root canals (MB, DB) of maxillary first (n = 170) and second (n = 157) molars superimpose the palatal one (P) at coronal and apical levels. The mean angles and standard deviations for both tooth types combined at which MB1 and MB2 overlap with P, as well as the angle at which DB overlaps with P, were 114.

Chlamydia and Gonorrhea Incidence and Residential Segregation: US Spatiotemporal Patterns (2013-2021).

Objective: Investigate how residential segregation is associated with chlamydia and gonorrhea incidence between 2013 and 2021.

Methods: National-level secondary US data from 2013-2021 from the Centers for Diseases Control and Prevention Sexually Transmitted Infection surveillance dataset, American Community Survey, and Racial Segregation Index were analyzed using the Generalized Estimating Equation, and spatial regression. Analysis was divided into two periods (2013-2019; 2020-2021) to account for COVID-19 disruptions.

Success and failure of endodontic treatment: predictability, complications, challenges and maintenance.

The fundamentals of successful endodontic treatment are an awareness of the aetiology of the disease process and an understanding of factors that affect outcome. This paper aims to outline the prognostic factors found in the endodontic outcome literature to facilitate options appraisal and predictable treatment delivery. We will discuss pre-treatment, treatment and post-treatment factors.
