Background The present study examined the effectiveness of the Universal Unified Prevention Program for Diverse Disorders (Up2-D2) for internalizing and externalizing problems for children aged 9–11 years. Methods We used two feasibility studies. The Up2-D2 entailed 12 sessions delivered by teachers; each session was developed based on cognitive-behavioral and positive psychological interventions. In Studies 1 and 2, 58 elementary school children aged 9–11 and 73 elementary school children aged 10–11 attended the Up2-D2. The teachers in Study 1 received 1.5 h of on-site teacher training for learning rationales for interventions, how to run the program, and received ongoing supervision by professionals with mental health expertise. In contrast, the teachers in Study 2 were given self-learning DVD materials in place of on-site training and ongoing supervision. Results Mixed models revealed that general difficulties, which is total score of both internalizing and externalizing problems, decreased in Study 1 but not in Study 2. Additional analyses for children with subclinical general difficulties revealed that general difficulties, internalizing problems, and externalizing problems decreased in Study 1, whereas in Study 2, general difficulties and internalizing problems decreased, except for externalizing problems. Conclusions These results suggest that on-site teacher training and ongoing supervision are imperative for improving general difficulties in children at a universal level. In addition, universal preventive interventions by classroom teachers without on-site training and continuous supervision might be efficacious for reducing general difficulties and internalizing problems for children with subclinical difficulties.

Prednisolone is a frequently prescribed steroid with a bitter, unpalatable taste that can result in treatment refusal. Oral suspensions or powder dosage forms are often prescribed, particularly to pediatric patients, as they improve swallowability and ease of dose adjustment. Consequently, the bitterness of prednisolone is more apparent in these dosage forms. Few studies have investigated prednisolone’s bitterness. Thus, in this study, 50 adults evaluated the bitterness of prednisolone using the generalized Labeled Magnitude Scale (gLMS), in comparison with quinine, a standard bitter substance. Overall, prednisolone-saturated solution demonstrated the same extent (mean gLMS score: 46.8) of bitterness as 1 mM quinine solution (mean gLMS score: 40.1). Additionally, large individual differences were observed in the perception of the bitterness of prednisolone and quinine. Perceived flavors of some drugs are reportedly associated with bitter-taste receptor (TAS2Rs) polymorphisms. Therefore, we investigated the relationship between subjects’ genetic polymorphisms of TAS2R19, 38, and 46, and their sensitivity to bitterness. Although a relationship between TAS2R19 polymorphisms and the perception of quinine bitterness was observed, no significant relationship was found between the perceived bitterness of prednisolone and the investigated genes. Ultimately, the results show that despite individual differences among subjects, the cause of prednisolone’s strong bitterness is yet to be elucidated.

Minitablets have garnered interest as a new paediatric formulation that is easier to swallow than liquid formulations. In Japan, besides the latter, fine granules are frequently used for children. We examined the swallowability of multiple drug-free minitablets and compared it with that of fine granules and liquid formulations in 40 children of two age groups (n = 20 each, aged 6–11 and 12–23 months). We compared the percentage of children who could swallow minitablets without chewing with that of children who could swallow fine granules or liquid formulations without leftover. The children who visited the paediatric department of Showa University Hospital were enrolled. Their caregivers were allowed to choose the administration method. In total, 37 out of 40 caregivers dispersed the fine granules in water. Significantly more children (80%, 95% CI: 56–94%) aged 6–11 months could swallow the minitablets than those who could swallow all the dispersed fine granules and liquid formulations (22%, 95% CI: 6–47% and 35%, 95% CI: 15–59%, respectively). No significant differences were observed in children aged 12–23 months. Hence, minitablets may be easier to swallow than dispersed fine granules and liquid formulations in children aged 6–11 months.

School closures due to the coronavirus disease 2019 (COVID-19) pandemic have worsened mental health problems for children and adolescents worldwide. We aimed to examine the follow-up effectiveness of a transdiagnostic universal prevention program for anxiety of junior high school students after a nationwide school closure during the COVID-19 outbreak in Japan. A total of 117 junior high school students were included in the analysis. We used the Unified Universal Prevention Program for Diverse Disorders (Up2-D2) program; the Up2-D2 comprises cognitive-behavioral and positive psychological interventions provided over twelve 45-minute sessions. The program was originally implemented between June and July 2020, immediately after pandemic-related school closures had ended in Japan. The program assessments were based on students’ responses to a questionnaire incorporating five scales to measure indicators such as internalizing and externalizing problems. Assessments were carried out before, immediately after, two-month, and six-month after implementing the program. Mixed models for the whole sample showed small anxiety improvement effects immediately post-intervention and two-month, and six-month assessments ( g = -0.25, g = -0.44, and g = -0.30, respectively). The anxiety reducing effects were even greater for the higher-anxiety group at the post-, 2-month, and 6-month assessments ( g = -1.48; g = -1.59; g = -1.06, respectively). Although there was no control group, these results indicate that the transdiagnostic universal prevention intervention reduce only anxiety, but not other outcomes (depression, anger, and self-efficacy) in junior high students returning to school following school closures related to the COVID-19 pandemic in Japan.

Background: Patients under resuscitation are at high risk for aspiration of gastric contents which causes ventilator-associated pneumonia. Therefore, blind nasogastric (NG) insertion is performed for decompression, however minimal trauma to the laryngopharynx can sometimes lead to severe bleeding in patients with a bleeding diathesis. Recently, the usefulness of NG tube placement under the assistance of a Video-laryngoscope (VLS) has reported. However, NG tube insertion is still performed blind, and insertion techniques to minimize mucosal injury during resuscitation are not well understood. We investigated laryngopharyngeal mucosal injury associated with blind NG tube insertion during resuscitation and considered practical blind NG tube insertion guidelines to minimize mucosal injury. Methods: We included patients (n = 84) with cardio pulmonary arrest on arrival in whom blind nasogastric tube insertion was possible within 120 s in the Blind group and those in whom it was not possible in the Difficult (Dif) group. In the Dif group, VLS-assisted nasogastric tube insertion was performed. The laryngopharyngeal mucosal condition was recorded after NG tube insertion using VLS. Patient background, success rates, insertion time, the number of insertions, and injury scores were evaluated. A single regression analysis was performed, and practical blind NG tube parameters for insertion during resuscitation were assessed. Results: Success rates in the Blind and Dif groups were 98.5% and 76.5%, respectively, and insertion times were 48.8 ± 4.0 and 54.8 ± 3.0 s, respectively. The number of insertions (2.1 ± 0.2 vs. 8.1 ± 0.8) and injury scores (1.04 ± 0.21 vs. 6.40 ± 0.64) in the Blind group were significantly lower than those in the Dif group, respectively. Mucosal injuries were most severe in the retropharyngeal wall in both groups. The number of insertions and insertion time both showed strong positive correlations with injury scores.Conclusion: The severity of laryngopharyngeal mucosal injury increased with increased insertion time and the number of insertions. Blind nasogastric tube insertion performed within 1 min or for a maximum of two or three attempts may minimize laryngopharyngeal mucosal injury, and VLS-assisted insertion should be considered if these limits are exceeded.
