Telepsychiatry: The future is already present.

This review paper analyzes the state of knowledge on Telepsychiatry (TP) after the crisis caused by COVID and the resulting need to use new modalities of care. Six essential aspects of TP are addressed: patient's and mental health staff satisfaction, diagnostic reliability, effectiveness of TP interventions, cost-effectiveness in terms of opportunity cost (or efficiency), legal aspects inherent to confidentiality and privacy in particular and the attitude of professionals toward TP. Satisfaction with TP is acceptable among both patients and professionals, the latter being the most reluctant. Diagnostic reliability has been demonstrated, but requires further studies to confirm this reliability in different diagnoses and healthcare settings. The efficacy of TP treatments is not inferior to face-to-face care, as has been proven in specific psychotherapies. Finally, it should be noted that the attitude of the psychiatrist is the most decisive element that limits or facilitates the implementation of TP.

Evaluating the Effect of a Telepsychiatry Educational Program on the Awareness, Knowledge, Attitude, and Skills of Telepsychiatry Among Spanish Psychiatrists during COVID-19 Pandemic.

Introduction: The COVID-19 pandemic has renewed the interest in telepsychiatry as a way to help psychiatrists care for their patients, but mental health providers' unfamiliarity and concerns may impede implementation of such services. This study aimed to determine the effect of an online educational intervention on awareness, knowledge, attitude, and skills (AKAS) of telepsychiatry among psychiatrists. Methods: The study used a pre-post-test design to compare AKAS of telepsychiatry among psychiatrists participating in an online course of practical telepsychiatry. The telemedicine AKAS questionnaire adapted to telepsychiatry was applied before and after the educational intervention, during the months of October to December 2020. Results: Responses from 213 participants were analyzed before the educational intervention and from 152 after it. The knowledge showed by Spanish psychiatrists before the educational intervention was good in 61% of participants, fair in 37%, and inadequate in 2%. With respect to attitudes toward telepsychiatry, 62% self-reported a high attitude, 33% moderate, and 5% low. With regard self-reported skills, 57% of the participating psychiatrists were highly skilled or experts, 22% moderately skilled, and 9% unskilled in handling telepsychiatry equipment. Despite the high baseline values, the educational intervention significantly improved psychiatrists' awareness, knowledge and attitudes toward telepsychiatry although not their skills. Conclusions: Online course of practical telepsychiatry was effective although future editions need to improve its focus on skills. This educational intervention represents an effort to promote the implementation of telepsychiatry as a health care alternative.

Effect of the hydration status of the smear layer on the wettability and bond strength of a self-etching primer to dentin.

PURPOSE: To evaluate the microtensile bond strength (MTBS) of a resin-based composite to smear layer-covered dentin using a self-etching primer, Clearfil SE Bond (CSEB), under two different hydration states. Surface roughness and wettability (contact angle measurements) of water and the CSEB primer were also evaluated on this substrate. METHODS: Contact angle (CA) measurements were performed on four caries-free extracted human third molars. The specimens were sectioned parallel to the occlusal surface to expose the moderately deep dentin and ground flat (180-grit SiC) under water to provide uniform flat surfaces. In two samples, the smear layer was completely air-dried; in the other two specimens, the smear layer was briefly air-dried. Contact angle measurements were performed to assess wettability of water and CSEB primer using the Axisymmetric Drop Shape Analysis technique. Surface roughness (SR) was determined with a contact profilometer. In another four molars, CSEB was applied to the smear layer-covered dentin with both hydration states. Resin build-ups were performed incrementally with Tetric Ceram. After storage for 24 hours in water at 37 degrees C, the teeth were sectioned to obtain bonded beams with an average cross-sectional area of 1.0 mm2. Each beam was tested in tension in an Instron machine at 0.5 mm/minute. Kolmogorov-Smirnov and Student t-tests were performed at a 95% significance level. RESULTS: Observed water contact angles were lower on the hydrated smear layer but no differences were found between contact angles on completely and briefly air-dried smear layer when the primer was used for CA measurements. SR was similar for both substrates and MTBS was greater when the adhesive was applied on the completely air-dried smear layer.
