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.

Understanding the bias of mobile location data across spatial scales and over time: A comprehensive analysis of SafeGraph data in the United States.

Mobile location data has emerged as a valuable data source for studying human mobility patterns in various contexts, including virus spreading, urban planning, and hazard evacuation. However, these data are often anonymized overviews derived from a panel of traced mobile devices, and the representativeness of these panels is not well documented. Without a clear understanding of the data representativeness, the interpretations of research based on mobile location data may be questionable.

Human mobility and the infectious disease transmission: A systematic review.

Recent decades have witnessed several infectious disease outbreaks, including the coronavirus disease (COVID-19) pandemic, which had catastrophic impacts on societies around the globe. At the same time, the twenty-first century has experienced an unprecedented era of technological development and demographic changes: exploding population growth, increased airline flights, and increased rural-to-urban migration, with an estimated 281 million international migrants worldwide in 2020, despite COVID-19 movement restrictions. In this review, we synthesized 195 research articles that examined the association between human movement and infectious disease outbreaks to understand the extent to which human mobility has increased the risk of infectious disease outbreaks.

Influence of root canal fillings on longevity of direct and indirect restorations placed within the General Dental Services in England and Wales.

Aim: To consider the survival of restorations in root filled and non-root filled teeth.

Methods: A data set was established consisting of patients, 18 years or older. For each patient on the database with a tooth restored with a direct or indirect restoration with or without a root filling, the subsequent history of intervention on that tooth was consulted, and the next date of intervention, if any could be found in the data set, was obtained.

[Giant bronchogenic cyst in a newborn infant].

A 12 hour old newborn suffering from respiratory distress was found to have a well defined opaque mass in the right lung. The mass was well tolerated up the 33rd day of life when he developed acute respiratory distress, the upper respiratory tract being flooded with secretions. Chest X ray showed that the mass had disappeared and that there was a large cystic structure instead.

[Thromboangiitis obliterans and distal gangrene in a 5-year-old child].

Distal gangrene associated with arterial hypertension but without systemic manifestations or muco-cutaneous eruptions was noted in a 5 years old child. Gangrene first appeared in toes and then in fingers. Progression in a 7 months period led to bilateral midleg amputation and amputation of several fingers.

[Diffuse cutaneous vasculitis disclosing acute lymphoblastic leukemia].

Biopsy of skin for etiologic evaluation of generalized erythematous eruptions in a 4 1/2 years old child, starting four months ago, led to diagnosis of acute lymphoblastic leukemia. Leukocyte counts five and eight weeks and four months after appearance of eruptions were normal and no blasts were found. A leukocyte count performed simultaneously with biopsy of skin also showed few (less than 10%) blasts.

[Acute hemiplegia due to cerebral artery occlusion in children. Apropos of 9 cases].

The cerebral arterial occlusion was observed from nine patients aged from 2,5 to 12 years old, between 37 children with acute acquired hemiplegia. The thrombosis had an embolic origin in three cases of cardiopathy. Six patients had primary arterial occlusion, but all these patients were febrile and the onset of hemiplegia was accompanied by seizures in five cases.

[Bone scan in the diagnosis of infectious osteoarthritis (author's transl)].

Bone scan with Technetium 99m is harmless method of evaluation of skeletal lesions. It is safe in pediatrics age group and it can be used in early diagnosis of infectious osteoarthritis. Bone scan differentiate osteomyelitis from cellulitis, and also it may help in diagnosis of subclinical involvement of rheumatoid arthritis, benign and malignant bone tumors, stress fractures and periositis.

[Papillon-Lefèvre syndrome and recurrent infections].

Seven cases of Papillon-Lefevre syndrome are described, 4 children and their mother with two other relatives on the mother's side. An immune defect was suspected because six of the seven had a history of severe pyogenic infections, but the results of the tests were not the same in the three individuals tested. In one patient no immune defect was detected but in the other two the response of lymphocytes to candida and to streptokinase and streptodornase was reduced.
