Background:
This study evaluated the effect of remimazolam and propofol on changes in autonomic nerve activity caused by surgical stimulation during orthognathic surgery, using power spectrum analysis of blood pressure variability (BPV) and heart rate variability (HRV), and their respective associations with cardiovascular fluctuations.
Methods:
A total of 34 patients undergoing Le Fort I osteotomy were randomized to the remimazolam (Group R, 17 cases) or propofol (Group P, 17 cases) groups. Observables included the low-frequency component of BPV (BPV LF; index of vasomotor sympathetic nerve activity), high-frequency component of HRV (HRV HF; index of parasympathetic nerve activity), balance index of the low- and high-frequency components of HRV (HRV LF/HF; index of sympathetic nerve activity), heart rate (HR), and systolic blood pressure (SBP). Four observations were made: (1) baseline, (2) immediately before down-fracture, (3) down-fracture, and (4) 5 min after down-fracture. Data from each observation period were compared using a two-way analysis of variance with a mixed model. A Bonferroni multiple comparison test was performed in the absence of any interaction.One-way analysis of variance followed by Tukey's multiple comparisons test was performed when a significant interaction was observed between time and group, with P < 0.05 indicating statistical significance.
Results:
Evaluation of autonomic nerve activity in comparison with baseline during down-fracture showed a significant increase in BPV LF (P < 0.001), an increasing trend in HRV LF/HF in Group P, and an increasing trend in HRV HF in Group R. There were no significant differences in HR or SBP between the two groups.
Conclusion
During down-fracture of Le Fort I osteotomy, sympathetic nerve activity was predominant with propofol anesthesia, and parasympathetic nerve activity was predominant with remimazolam anesthesia.

Objectives:
The coronavirus disease 2019 pandemic and its associated societal responses are anticipated to have wide-ranging effects on youth development and mental health. Depression, anxiety, and attention deficit hyperactivity disorder (ADHD) are the three most common mental health problems among university students. Many factors that can threaten mental health during the outbreak affect these three conditions, as well as sleep conditions, in undergraduate students. Thus, determining how these abrupt changes in students’ circumstances impact their mental health is very important from a public health perspective.
Methods:
We investigated the usual conditions and changes in ADHD symptoms during the outbreak, in relation to depressive and sleep-related symptoms among undergraduate students. A total of 252 students, primarily juniors, completed the online survey.
Results:
The results showed that 12% of the students exceeded the cut-off score of the ADHD questionnaire before the pandemic.Approximately 6%–21% of the university students, especially those with ADHD traits, rated their ADHD behaviors as worse during the outbreak than that before the outbreak.
Conclusion
Female students and undergraduates with ADHD traits are more susceptible to experiencing further deterioration of ADHD (inattention) symptoms during the pandemic. In cases where it is difficult to intervene with ADHD symptoms, approaching circadian rhythm or depression will be of considerable clinical use.

Objective: Many patients in Kagawa University Hospital are administered medicines prepared by the simple suspension method. Pharmacists in charge of these patients receive inquiries from doctors and nurses regarding the suitability of medicines for the simple suspension method. Answering these inquiries is complicated and time-consuming as multiple data sources need to be searched. In order to simplify these complicated procedures, we herein attempted to develop a novel database to provide valuable information that could contribute to the safe performance of the simple suspension method, and evaluated its usefulness.
Method: The specifications of the database were determined by analyzing previously answered inquiries. To evaluate the usefulness of the database, we used test prescriptions and compared the amount of time required to gather information using the database and the conventional method, i.e., using books alone. We also analyzed previous prescriptions with the database in order to determine what kinds of problems could be detected.
Results: The investigation of previous prescriptions indicated that some medicines needed to be examined not only for their suitability for the simple suspension method, but also their incompatibility. Therefore, we added a feature regarding the incompatibility of medicines to the database. The time required to gather the information needed to answer the test prescription was shorter with our database than with the conventional method. Furthermore, the database improved the detection of medicines that require particular attention for their properties including incompatibility. An analysis of previous prescriptions using our database indicated the possibility of incompatibility in half of the previous prescriptions examined.
Conclusion: Our database could rapidly provide information related to the simple suspension method, including the incompatibility of medicines.

BACKGROUND/AIMS: Noninvasive liver fibrosis evaluation was performed in patients with nonalcoholic fatty liver disease (NAFLD). We used a quantitative method based on the hepatic volume acquired from gadoxetate disodium-enhanced (Gd-EOB-DTPA-enhanced) magnetic resonance imaging (MRI) for diagnosing advanced fibrosis in patients with NAFLD. METHODS: A total of 130 patients who were diagnosed with NAFLD and underwent Gd-EOB-DTPA-enhanced MRI were retrospectively included. Histological data were available for 118 patients. Hepatic volumetric parameters, including the left hepatic lobe to right hepatic lobe volume ratio (L/R ratio), were measured. The usefulness of the L/R ratio for diagnosing fibrosis ≥F3–4 and F4 was assessed using the area under the receiver operating characteristic (AUROC) curve. Multiple regression analysis was performed to identify variables (age, body mass index, serum fibrosis markers, and histological features) that were associated with the L/R ratio. RESULTS: The L/R ratio demonstrated good performance in differentiating advanced fibrosis (AUROC, 0.80; 95% confidence interval, 0.72 to 0.88) from cirrhosis (AUROC, 0.87; 95% confidence interval, 0.75 to 0.99). Multiple regression analysis showed that only fibrosis was significantly associated with the L/R ratio (coefficient, 0.121; p<0.0001). CONCLUSIONS: The L/R ratio, which is not influenced by pathological parameters other than fibrosis, is useful for diagnosing cirrhosis in patients with NAFLD.

Clinical training programs play an extremely important role in the new postgraduate clinical training system introduced in 2004 because facilities for clinical training now include various health-related institutions in addition to the university hospitals and special hospitals for clinical training used in the previous system. Although educational goals have been established by the Ministry of Health, Labour and Welfare, trainees may have difficulty achieving these goals, even under the guidance of staff at the various facilities. There are differences in the function and quality of health-related institutions in the community. For the practical and convenient application of educational goals, we have attempted develop a “model program” to supplement the objectives indicated by the learning goals with more specific objectives. These supplementary objectives can be modified by individual institutions. We hope that this “model program” contributes to the development of objectives for each institution and helps improve the quality of the postgraduate training system in Japan.
