Telessaúde no Brasil: uma revisão de escopo / Telehealth in Brazil: a scoping review / Telesalud en Brasil: una revisión de alcance

Este artigo buscou conhecer o desenvolvimento da telessaúde no Brasil, desde a sua efetivação e ampliação a partir das publicações científicas sobre o tema pela implementação do Programa Nacional de Telessaúde Brasil Redes em 2007. Esta é uma revisão de escopo de estudos indexados nas bases Medical Literature Analysis and Retrieval System Online (Medline), Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs) e Scientific Electronic Library Online (SciELO) de 2007 a 2022 que abordaram ações de telessaúde. Incluíram-se 177 estudos, publicados majoritariamente nos anos de 2021 e 2020. Ações de telessaúde foram realizadas especialmente nas regiões Sudeste e Sul, sendo o telediagnóstico e teleconsultoria as mais realizadas. A medicina foi a área em que as ações de telessaúde foram mais frequentes (54,80%), focadas principalmente na saúde em geral e na cardiologia (38,42% e 19,21% respectivamente). Conclui-se que a telessaúde no Brasil tem avançado, especialmente após a pandemia da covid-19, que deflagrou a necessidade da ampliação desses serviços. As regiões Sudeste e Sul têm ofertado o maior número de serviços, sendo o telediagnóstico e a teleconsultoria os mais frequentes, especialmente na atenção primária.

This scoping review discusses the development of telehealth in Brazil from its implementation by the Brasil Redes National Telehealth Program in 2007 and expansion based on scientific publications on the topic indexed on the Medical Literature Analysis and Retrieval System Online (Medline), Latin American and Caribbean Health Sciences Literature (Lilacs) and Scientific Electronic Library Online (SciELO) from 2007 to 2022. A total of 177 studies were included, mostly published in 2021 and 2020. Telehealth actions were conducted especially in Southeastern and Southern Brazil, mostly by telediagnosis and teleconsultation. Telehealth actions were most frequent in medicine (54.80%), mainly focused on General Health and cardiology (38.42% and 19.21%, respectively). Telehealth in Brazil has advanced, especially after the COVID-19 pandemic, as it triggered the need to expand these services. Southeastern and Southern Brazil have offered the largest number of services, with telediagnosis and teleconsultation in primary care being the most frequent.

Titanium dioxide nanotubes added to glass ionomer cements affect S. mutans viability and mechanisms of virulence.

This in vitro study evaluated the impact of TiO2 nanotubes (n-TiO2) incorporated into glass ionomer cement (GIC) on Streptococcus mutans (S. mutans) characteristics at cellular and molecular levels. n-TiO2, synthesized by the alkaline method (20 nm in size), was added to Ketac Molar EasyMix® at 0%, 3%, 5%, and 7% by weight. S. mutans strains were cultured on GIC disks with addition or not of n-TiO2 for 1, 3, and 7 days and the following parameters were assessed: inhibition halo (mm) (n=3/group); cell viability (live/dead) (n=5/group); cell morphology (SEM) (n=3/group); and gene expression by real-time PCR (vicR, covR, gtfB, gtfC, and gtfD) (n=6/group). The data were analyzed by the Kruskal-Wallis test, repeated-measures ANOVA or two-way ANOVA, and Tukey's and Dunn's post-hoc tests (α=0.05). The agar diffusion test showed a higher antibacterial property for 5% n-TiO2 compared with 3% and 7% (p<0.05) with no effect of time (1, 3, and 7 days). The cell number was significantly affected by all n-TiO2 groups, while viability was mostly affected by 3% and 5% n-TiO2, which also affected cell morphology and organization. Real-time PCR demonstrated that n-TiO2 reduced the expression of covR when compared with GIC with no n-TiO2 (p<0.05), with no effect of time, except for 3% n-TiO2 on vicR expression. Within-group and between-group analyses revealed n-TiO2 did not affect mRNA levels of gtfB, gtfC, and gtfD (p>0.05). Incorporation of n-TiO2 at 3% and 5% potentially affected S. mutans viability and the expression of key genes for bacterial survival and growth, improving the anticariogenic properties of GIC.

Extraoral Implants for Anchoring Facial Prostheses: Evaluation of Success and Survival Rates in Three Anatomical Regions.

PURPOSE: The aim of this study was to evaluate the success and survival rates of extraoral implants for the fixation of facial prostheses in three anatomical regions. MATERIALS AND METHODS: Subjects were consecutive patients with facial defects who underwent implant placement by the same surgeon in the orbital, nasal, and auricular regions between 2003 and 2012. After a minimum of 4 months of osseointegration, prostheses were anchored to the implants, and the patients were monitored for 11 to 111 months. Success rate, implant survival time, and occurrence of previous radiotherapy were evaluated. Rate of implant survival was estimated as a function of the anatomical region of the three groups (orbital, nasal, or auricular), and confidence intervals were calculated using Kaplan-Meier analysis with α = .05. RESULTS: In the 68 patients' 138 fixed implants, 48 showed defects in the orbital, 9 in the nasal, and 11 in the auricular region. The success rates and survival times were 95.9% and 8.6 years for the orbital, 92.9% and 2.8 years for the nasal, and 92% and 9.0 years for the auricular region, respectively. The success rate of implants in previously irradiated regions was 90.3% for the orbital and 100% for the auricular region. None of the patients was irradiated in the nasal region. CONCLUSION: No significant differences in implant success or survival were observed with regard to anatomical region or previous irradiation.

Orbit rehabilitation with extraoral implants: impact of radiotherapy.

PURPOSE: The aim of the study was to compare the success rates of osseointegration among irradiated and nonirradiated cases submitted to implant placement for anchorage of orbit prostheses from 2003 to 2011. MATERIALS AND METHODS: Charts of 45 consecutive patients were analyzed, 31 men and 14 women, and they were divided in two groups, considering previous irradiation therapy. Nonirradiated group had 33 patients, and irradiated group had 12 patients. In total, 138 implants were installed, 42 (30.4%) in previously irradiated bone. RESULTS: The overall implant survival rate was 96.4% with a success rate of 99.0% among the nonirradiated patients and 90.5% among the irradiated patients (p = 0.03). CONCLUSIONS: Results showed that irradiated sites had a worse prognosis related to success of osseointegration, although the 90.5% survival rate in this group indicates that implant placement is a feasible alternative to anchor orbit prostheses considering the benefits that this technique offers to patients.
