Purpose: To examine the efficacy of selective repetitive transcranial magnetic stimulation (rTMS) therapy guided by functional near-infrared spectroscopy (fNIRS) combined with intensive speech therapy (iST) on post-stroke patients with aphasia. Material and Methods: Eight right-handed patients with aphasia in the chronic stage after stroke were grouped into left and right hemisphere-activated for a language task based on pre-intervention fNIRS. Those with left hemisphere activation received 1-Hz TMS to the right inferior frontal gyrus (RtIFG; low-frequency rTMS [LFS] group), and those with right hemisphere activation received 10-Hz TMS to the RtIFG (high-frequency rTMS [HFS] group). The patients underwent an 11-day program of rTMS and iST. Results: Both groups showed a significant improvement in language function as measured by Standard Language Test of Aphasia (SLTA) total score at post-intervention relative to pre-intervention. Furthermore, the pre-to-post SLTA change scores were not statistically different between the groups. Comparison of pre- and post-intervention fNIRS revealed a resolution of the imbalance of interhemispheric inhibition in the LFS group and activation of the target hemisphere in the HFS group. Conclusions: The administration of fNIRS-guided selective rTMS therapy and iST to post-stroke patients with aphasia induced a significant improvement in language function, with both groups demonstrating a similar degree of improvement.

This study systematically reviewed the literature on perceived school safety. We investigated the prevalence, factors and associated mental health difficulties, as well as cross-cultural findings. Five databases were searched up to 9 February 2021 for peer-reviewed papers published in English. We included quantitative studies that explored the perception of school safety among children and adolescents. The reference lists of the selected papers were also searched. We conducted a narrative synthesis of the included studies. The review included 43 papers. The mean prevalence of the students who felt unsafe at school was 19.4% and ranged from 6.1% to 69.1%. Their perceived safety was associated with a wide range of personal, school, and social factors. Not feeling safe at school was related to being victimized and mental health difficulties, including depressive symptoms and suicidal behavior. Higher perceived school safety was associated with measures such as the presence of a security officer and fair school rule enforcement. The results showed the lack of cross-cultural studies on perceived school safety. Empirical studies are needed that examine the mechanisms of school safety, using valid measures. A clear definition of school safety should be considered a key aspect of future studies.

We evaluated the usefulness of a short professional mechanical tooth-cleaning (PMTC) program to improve periodontal conditions and caries susceptibility in 10 young adult patients with mental and/or physical disabilities. The PMTC program was carried out once on each of 6 sextants of the full mouth during 6 visits at two-week intervals. Even one treatment with PMTC was found to be significantly effective in reducing the probing depth in eight of the 10 subjects. A reduction in the total number of bleeding sites on probing was also clearly observed in all subjects. Moreover, the debris index was reduced in nine subjects by the PMTC program. Although caries susceptibility was improved, albeit very slowly, by PMTC, the Cariostat pH values showed no consistent tendency. The effects lasted for more than 6 weeks. Analysis of these results suggests that the PMTC program can be effective in adults with mental disabilities, especially in reducing gingival inflammation.
