Emergency department use for nontraumatic dental conditions for children with special health care needs enrolled in Oregon Medicaid.

Background: This cross-sectional study evaluated whether children with special health care needs (CSHCN) were more likely to use the emergency department (ED) for nontraumatic dental conditions (NTDCs) than children without special health care needs (SHCN). The study also examined whether the likelihood of receiving an opioid prescription after an NTDC-ED visit differed between children with and without SHCN.

Methods: This analysis was based on 2017 Oregon Medicaid enrollment, claims, and pharmacy data (N = 225,614 children aged 3-17 years).

Reaction of Isatin and 2-Chloropyridinium Salt: An Efficient and Diastereoselective Synthesis of α,β-Unsaturated Oxindoles.

A new, mild, and diastereoselective method has been developed for the synthesis of β-pyridone-α,β-unsaturated oxindoles by the reaction of isatins and 2-chloropyridinium salts in EtOH at room temperature for 5 min. This method operates under mild reaction conditions, providing the product with a good yield and diastereoselectivity, and it exhibits excellent tolerance toward various functional groups. The predominant isomer is the isomer, which can convert to the isomer in the presence of NaN.

3D printable and mechanically tunable hydrogels achieved through hydrophobic and ionic interactions.

Thermal stiffening materials are commonly applied in the aerospace and automotive industries, among others, since their dimensional stabilities and stiffness characteristics improve at high temperatures. In this study, temperature-triggered modulus-tunable hydrogels were prepared by combining Pluronic F-127 with charged polymers. Pluronic F-127, a triblock copolymer micelle, provided three-dimensional printing capabilities of fine resolution with high viscosity, while hydrophobic and ionic interactions among polymer networks provided thermal stiffening.

Seamless Integration of Conducting Hydrogels in Daily Life: From Preparation to Wearable Application.

Conductive hydrogels (CHs) have received significant attention for use in wearable devices because they retain their softness and flexibility while maintaining high conductivity. CHs are well suited for applications in skin-contact electronics and biomedical devices owing to their high biocompatibility and conformality. Although highly conductive hydrogels for smart wearable devices are extensively researched, a detailed summary of the outstanding results of CHs is required for a comprehensive understanding.

Preventive dental care utilization and dental caries for Medicaid-enrolled adolescents in Oregon.

Objectives: This study aimed to evaluate the relationship between preventive dental care utilization and untreated dental caries for Medicaid-enrolled adolescents and to determine if the relationship is moderated by chronic conditions (CC).

Methods: This analysis was based on 2015-2016 Medicaid claims files and survey data collected from adolescents ages 12-18 years enrolled in Oregon Medicaid, who received a dental screening between December 2015 and December 2016 (n = 240). To assess the relationship between preventive dental care utilization and untreated dental caries (defined as decayed tooth surfaces), prevalence ratios (PR) and 95% confidence intervals (CI) were generated using log-linear regression models.
