Factors affecting the risk of trismus following maxillary ablative surgery comparing free flap reconstruction to prosthetic obturation: a retrospective observational study.

The reconstruction of post-ablative maxillary defects is controversial. It is accepted that quality of life indicators are poorer for maxillary reconstruction compared with mandibular reconstruction. One factor highlighted is that of post-treatment trismus.

Is Insurance Payor Associated With Hospital Admission of Emergency Department Adult Patients With Odontogenic Infections?

Background: Patients who present to the emergency department (ED) with severe odontogenic infections are often hospitalized for surgical drainage and medical management. However, inpatient management of these patients can be financially burdensome. While medical indications for hospital admission are well established, it remains unclear if patient insurance status is associated with admission.

The influence of air masses on human mortality in the contiguous United States.

Temperature-related mortality is the leading cause of weather-related deaths in the United States. Herein, we explore the effect of air masses (AMs) - a relatively novel and holistic measure of environmental conditions - on human mortality across 61 cities in the United States. Geographic and seasonal differences in the effects of each AM on deseasonalized and detrended anomalous lagged mortality are examined using simple descriptive statistics, one-way analyses of variance, relative risks of excess mortality, and regression-based artificial neural network (ANN) models.

Engineering self-propelled tumor-infiltrating CAR T cells using synthetic velocity receptors.

Chimeric antigen receptor (CAR) T cells express antigen-specific synthetic receptors, which upon binding to cancer cells, elicit T cell anti-tumor responses. CAR T cell therapy has enjoyed success in the clinic for hematological cancer indications, giving rise to decade-long remissions in some cases. However, CAR T therapy for patients with solid tumors has not seen similar success.

Circulation patterns associated with trends in summer temperature variability patterns in North America.

This study improves the understanding of circulation patterns associated with regional temperature trends by characterizing boreal summer temperature variability patterns in North America using rotated S-mode principal component analysis. We analyzed gridded observational 2-m temperature datasets and the ERA5 reanalysis temperature dataset to examine the climate patterns associated with long-term trends and inter-annual variability of temperature variability patterns in North America. Our analysis revealed significant trends among some classified temperature variability patterns from 1979 to 2022 summers, with inter-annual amplitudes (i.

Females Have Worse Overall and Disease-Specific Survival in Human Papillomavirus-Negative Oropharyngeal Squamous Cell Carcinoma.

Purpose: Although sex (male vs female) has been identified as an independent prognostic factor in human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC), the role of sex in HPV-negative OPSCC is less understood. The purpose of this study is to measure the association between sex and HPV-negative OPSCC disease-specific survival (DSS) and overall survival (OS).

Methods: This longitudinal, retrospective study examined cases of HPV-negative OPSCC diagnosed in the United States between 2013 and 2016 from the Surveillance, Epidemiology, and End Results database.

Correction of Traumatic Transverse Mandibular Widening With Interdental Wiring.

Mandibular symphysis fractures pose several technical challenges for the craniomaxillofacial surgeon. One classic challenge is restoration of the transverse dimension when the mandible is widened secondary to splaying of the lingual cortex. Failure to diagnose or correct this problem can result in widening of the lower facial third, inadequate fracture reduction, and/or a malocclusion.
