Utilization Trends and Predictors of Non-invasive and Invasive Ventilation During Hospitalization Due to Community-Acquired Pneumonia.

Background: Community-acquired pneumonia (CAP) is associated with significant morbidity and mortality. Non-invasive ventilation (NIV) and invasive mechanical ventilation (IMV) are most important interventions for patients with severe CAP associated with respiratory failure. We analysed utilization trends and predictors of non-invasive and invasive ventilation in patients hospitalized with CAP.

Evaluation and Management of Impacted Teeth in the Adolescent Patient.

The most common oral and maxillofacial surgical procedure in adolescents is excision of impacted third molars. Adolescent patients should be evaluated for third molars starting around age 16 years unless symptomatic at an earlier age. The dental examination should include panorex imaging to assess development, pathologic condition, and possibility of eruption versus impaction.

Adolescent Orofacial Trauma.

Facial and dental-related trauma is common in the pediatric population. Appropriate evaluation and management techniques should be followed. Initial evaluation of the medical condition of the patient should be completed with acute management of any medical-related problems as a priority.

Pediatric Endodontic Treatment of Adolescent Patients.

This article is intended to familiarize clinicians with several pulp therapy modalities and new materials that are currently available for immature young pulp in the adolescent population. Objectives and considerations for immature young permanent teeth as well as the healing potential of the young pulp tissue after treatment of the inflammatory process are discussed. The article emphasizes that the future holds great possibilities for the regeneration of dental pulp in adolescent patients.

Eating Disorders in the Adolescent Patient.

Eating disorders such as anorexia nervosa, female athlete triad, bulimia nervosa, obesity, and binge eating initially emerge during adolescence. These disorders are present primarily in females, but males may also present with these conditions. Dentistry has a pivotal role in the management of patients with such diet-related disorders.

Study protocol: A stepped-wedge, cluster-randomized trial of the effectiveness of a deliberative loop in identifying implementation strategies for the adoption of a dental sealant guideline in dental clinics.

Background: The American Dental Association (ADA) recommends dental providers apply dental sealants to the occlusal surfaces of permanent molars for the prevention or treatment of non-cavitated dental caries. Despite the evidence-based support for this guideline, adherence among general dentists is low, ranging from less than 5 to 38.5%.

Race and payor type for child visits with public health dental hygienist practitioners.

Purpose: To examine whether growth in visits to public health dental hygiene practitioners (PHDHPs) providing preventative dental services at a pediatric hospital clinic was predominantly among children receiving public insurance and children of minority background from 2013 to 2017.

Methods: Longitudinal descriptive data analysis from electronic health records for 6856 children under age 18 years who visited PHDHPs co-located at a hospital clinic in Pittsburgh, PA, from 2013 to 2017. We compared visits between white versus non-white children and between children with public, private, and no or missing insurance by year.

Acute DNA Methylation Trajectories in Cerebrospinal Fluid and Associations With Outcomes Following Severe Traumatic Brain Injury in Adults.

Caveolin-1 mediates soft scaffold-enhanced adipogenesis of human mesenchymal stem cells.

Background: Human bone marrow-derived mesenchymal stem cells (hBMSCs) can differentiate into adipocytes upon stimulation and are considered an appropriate cell source for adipose tissue engineering. In addition to biochemical cues, the stiffness of a substrate that cells attach to has also been shown to affect hBMSC differentiation potential. Of note, most current studies are conducted on monolayer cultures which do not directly inform adipose tissue engineering, where 3-dimensional (3D) scaffolds are often used to create proper tissue architecture.

History of dysplasia and primary site associated with recurrence in T1N0 oral squamous cell carcinoma.

Objective: Recurrent disease occurs in a significant proportion of early-stage oral squamous cell carcinoma (OSCC) despite removal of the entire tumor with clear surgical margins. Our study sought to identify clinicopathologic factors that increase the risk of locoregional recurrence in T1N0 OSCC.

Study Design: We conducted an observational retrospective analysis of 65 cases of T1N0 OSCC over a period of 13 years.

Conversion of α-Cells to β-Cells in the Postpartum Mouse Pancreas Involves Lgr5 Progeny.

In contrast to the skin and the gut, where somatic stem cells and their niche are well characterized, a definitive pancreatic multipotent cell population in the adult pancreas has yet to be revealed. Of particular interest is whether such cells may be endogenous in patients with diabetes, and if so, can they be used for therapeutic purposes? In the current study, we used two separate reporter lines to target Cre-recombinase expression to the Lgr5- or glucagon-expressing cells in the pancreas. We provide evidence for the existence of a population of cells within and in the proximity of the ducts that transiently express the stem-cell marker Lgr5 during late gestational stages.

Activation of creER recombinase in the mouse calvaria induces local recombination without effects on distant skeletal segments.

Conditional creER-mediated gene inactivation or gene induction has emerged as a robust tool for studying gene functions in mouse models of tissue development, homeostasis, and regeneration. Here, we present a method to conditionally induce cre recombination in the mouse calvarial bone while avoiding systemic recombination in distal bones. To test our method, we utilized Prx1creER-egfp;td-Tomato mice and delivered 4-hydroxytamoxifen (4-OHT) to the mouse calvaria, subperiosteally.

The effect of plaque control in the treatment of Oral Lichen Planus with gingival manifestations: a Systematic Review.

Background: Oral lichen planus (OLP) is a chronic autoimmune disease that frequently affects the oral mucosa. Patients with OLP tend to present with plaque accumulation which may further exacerbate the lichenoid lesion, thus plaque control may improve the quality of life of patients. The aim of this review was to test the effect of plaque control on OLP with gingival manifestations.

Psychometric analysis of the module's test items confirmed reliability and validity.

Trps1 transcription factor represses phosphate-induced expression of SerpinB2 in osteogenic cells.

Serine protease inhibitor SerpinB2 is one of the most upregulated proteins following cellular stress. This multifunctional serpin has been attributed a number of pleiotropic activities, including roles in cell survival, proliferation, differentiation, immunity and extracellular matrix (ECM) remodeling. Studies of cancer cells demonstrated that expression of SerpinB2 is directly repressed by the Trps1 transcription factor, which is a regulator of skeletal and dental tissues mineralization.

How to Teach Medical Students About Pain and Dementia: E-Learning, Experiential Learning, or Both?

Objective: Pain management in persons with mild to moderate dementia poses unique challenges because of altered pain modulation and the tendency of some individuals to perseverate. We aimed to test the impact of an e-learning module about pain in communicative people with dementia on third-year medical students who had or had not completed an experiential geriatrics course.

Design: Analysis of pre- to postlearning changes and comparison of the same across the student group.

Condyle modeling stability, craniofacial asymmetry and ACTN3 genotypes: Contribution to TMD prevalence in a cohort of dentofacial deformities.

Craniofacial asymmetry, mandibular condylar modeling and temporomandibular joint disorders are common comorbidities of skeletally disproportionate malocclusions, but etiology of occurrence together is poorly understood. We compared asymmetry, condyle modeling stability and temporomandibular health in a cohort of 128 patients having orthodontics and orthognathic surgery to correct dentofacial deformity malocclusions. We also compared ACTN3 and ENPP1 genotypes for association to clinical conditions.
