StandUPTV: Preparation and optimization phases of a mHealth intervention to reduce sedentary screen time in adults.

Recreational sedentary screen time (rSST) is the most prevalent sedentary behavior for adults outside of work, school, and sleep, and is strongly linked to poor health. StandUPTV is a mHealth trial that uses the Multiphase Optimization Strategy (MOST) framework to develop and evaluate the efficacy of three theory-based strategies for reducing rSST among adults. This paper describes the preparation and optimization phases of StandUPTV within the MOST framework.

Personalized digital behaviour interventions increase short-term physical activity: a randomized control crossover trial substudy of the MyHeart Counts Cardiovascular Health Study.

Aims: Physical activity is associated with decreased incidence of the chronic diseases associated with aging. We previously demonstrated that digital interventions delivered through a smartphone app can increase short-term physical activity.

Methods And Results: We offered enrolment to community-living iPhone-using adults aged ≥18 years in the USA, UK, and Hong Kong who downloaded the MyHeart Counts app.

Off-label use of recombinant human bone morphogenetic protein-2 (rhBMP-2) for reconstruction of mandibular bone defects in humans.

Purpose: The off-label use of recombinant human bone morphogenetic protein-2 (rhBMP-2) for the treatment of mandibular bone defects was evaluated in 5 patients. The rhBMP-2 was used as an alternative to autogenous bone grafting.

Patients And Methods: A total of 5 patients had mandibular defects reconstructed with rhBMP-2, 1.

A prospective randomized clinical trial comparing 2.0-mm locking plates to 2.0-mm standard plates in treatment of mandible fractures.

Purpose: The purpose of this study was to compare standard 2.0-mm monocortical plates to 2.0-mm locking plates in the treatment of mandible fractures.

Neurohumorally induced cardiac dysrhythmias during nitrous oxide-oxygen-thiopental anesthesia.

Barbiturate, nitrous oxide, and oxygen are commonly used by the oral and maxillofacial surgeon to anesthetize the ambulatory oral surgery patient. The authors report three cases of ventricular dysrhythmia occurring from surgical stimulation during nitrous oxide-oxygen-thiopental anesthesia. These dysrhythmias were most likely mediated via direct neural stimulation of cardiac sympathetic nerves.

Arterial plasma epinephrine concentrations and hemodynamic responses after dental injection of local anesthetic with epinephrine.

The effect of dental injection of local anesthetic on arterial plasma epinephrine concentrations and cardiovascular functions was assessed in patients having a maxillary third molar extracted. After three and five minutes, arterial plasma epinephrine concentrations were more than two times higher than baseline values in patients who were given an injection of a standard Carpule (1.8 ml) of 2% lidocaine with 1/100,000 epinephrine (18 micrograms).

Arterial-venous differences of plasma catecholamines in man.

To investigate the relationship between forearm venous levels of catecholamines and systemic levels, simultaneous arterial and forearm vein blood samples were obtained from 14 subjects undergoing elective dental procedures and assayed with a sensitive and specific radioenzymatic assay. Baseline venous levels of norepinephrine were greater than arterial levels (305 +/- 30 pg/ml versus 221 +/- 18; +/- SEM, p less than .005).
