Objectives: We aimed to identify which resting echocardiographic parameters can detect asymptomatic or mildly symptomatic patients with primary mitral regurgitation (MR) who require exercise stress echocardiography (ESE) to determine their suitability for surgery.

Methods: We examined 56 consecutive patients with primary moderate/severe MR who underwent ergometer-based ESE. Patients who met the surgical indications at rest were excluded. Eligible patients were divided into Group I (pulmonary artery systolic pressure [PASP] during exercise >60 mmHg; n=11) and Group II (PASP during exercise ≤60 mmHg; n=30).

Results: Forty-one patients were included. Group I was significantly older (65±12 vs. 54±14 years, P=0.042) and had significantly higher serum N-terminal pro-B-type natriuretic peptide concentrations than Group II (351±278 vs. 125±163 pg/mL, P=0.002). The univariate analysis demonstrated that peak E wave velocity (Group I vs. Group II: 125±45 vs. 101±24 cm/sec, P=0.050), left ventricular (LV) end-diastolic diameter index (32±4 vs. 30±3 mm/m², P=0.035), and left atrial volume index (LAVI; 45±14 vs. 30±11 mL/m², P=0.008) were predictors of increased PASP during exercise. In the multivariate analysis, resting LAVI best predicted exercise-induced pulmonary hypertension (hazard ratio 1.081 [95% confidence interval 1.009–1.158], P=0.028), with a cutoff value of 37 mL/m².

Conclusions: In asymptomatic or mildly symptomatic patients with primary moderate/severe MR, increased resting LAVI indicates the requirement for ESE, even without LV dilatation.

Objectives: Antiemetics have been widely recommended for treating opioid-induced nausea and vomiting (OINV). According to a previous study, the use of prophylactic prochlorperazine at the initiation of treatment with oral oxycodone was ineffective in preventing OINV. This study examined whether prochlorperazine injection prevents OINV and induces drowsiness in patients with end-stage cancer (a different patient population from the previous study).

Methods: Patients with end-stage cancer who received opioid injections for more than 5 days between April 2017 and March 2020 were classified into two groups: the opioid and prochlorperazine injection group and opioid alone group. Their systemic conditions were evaluated on the basis of the performance status and the palliative performance scale, a prognostic indicator.

Results: Of 325 patients who received opioid treatment during the study period, 156 patients met the inclusion criteria. Of these, 103 patients and 53 patients were classified into the opioid and prochlorperazine injection group (prochlorperazine) and opioid alone groups (placebo) , respectively. There was no significant difference in characteristics, age, gender, performance status, or palliative performance scale results between the 2 groups. OINV developed in 4 patients in the opioid and prochlorperazine injection groups and in 1 patient in the opioid alone group. Given that sleep disturbance develops in many patients with end-stage cancer who had a specific condition, it is difficult to conclude regarding the relationship between prochlorperazine injection and drowsiness, although this study examined this relationship.

Conclusions: As with the previous study, prophylactic prochlorperazine injection was ineffective in preventing OINV in patients who received opioid injections.

Objectives: The Gunma score is used to predict the severity of Kawasaki disease (KD), including coronary artery aneurysm (CAA) as a cardiac complication, in Japan. Additionally, the characteristic ratio of ventricular repolarization (T-peak to T-end interval to QT interval [Tp-e/QT]) on a surface electrocardiogram reflects myocardial inflammation. This study aimed to determine whether the Tp-e/QT can be used to predict CAA in children with KD.

Methods: We analyzed chest surface electrocardiograms of 112 children with KD before receiving intravenous immunoglobulin therapy using available software (QTD; Fukuda Denshi, Tokyo, Japan).

Results: The Tp-e/QT (lead V5) was positively correlated with the Gunma score (r=0.352, p<0.001). The Tp-e/QT was larger in patients with CAA (residual CAA at 1 month after onset) than in those without CAA (0.314±0.026 versus 0.253±0.044, p=0.003). A receiver operating characteristic curve analysis was performed to assess whether the Gunma score and Tp-e/QT could predict subsequent CAA. The area under the curve of the Gunma score was 0.719 with the cutoff set at 5 points. The area under the curve of the Tp-e/QT was 0.892 with a cutoff value of 0.299. The fit of the prediction models to the observed probability was tested by the Hosmer–Lemeshow test with calibration plots using Locally weighted scatterplot smoothing (LOESS) fit. The Gunma score (p=0.95) and Tp-e/QT (p=0.95) showed a good fit.

Conclusions: The Tp-e/QT is a useful biomarker in predicting coronary aneurysm complications in KD.

Objectives: The purpose of this study was to capture the lifestyle characteristics of traumatic brain injury (TBI) patients by administering the Frenchay Activities Index (FAI), a self-assessment questionnaire used for assessing life-related activities, among TBI patients.

Methods: This study was conducted using the revised FAI Self-Assessment Form, administering an interview-based questionnaire survey to TBI patients and healthy participants. The target group comprised 60 traumatic brain injury patients who had progressed from at least 1 year since the injury, with a comparison group of 788 healthy participants.

Results: A comparison of FAI scores between TBI patients and healthy participants by questionnaire revealed that TBI patients exhibited significantly higher FAI scores than healthy participants for outdoor walking and transportation use (Mann–Whitney U test, P<0.01). A comparison by occupation revealed that TBI patients were significantly less among the unemployed and other categories (Mann–Whitney U test, P<0.01). For office workers, government employees, high school students, and college students, scores were higher among TBI patients compared with healthy participants, although the differences were not significant.

Conclusions: Although TBI patients were less active than healthy participants in life-related activities, their scores for cleaning up after meals and cleaning and putting things in order were close to those of healthy participants, indicating that TBI patients cannot be considered to be inactive. The findings also revealed differences in TBI patients’ engagement in life-related activities and frequency of activities depending on their social position.

Objectives: This study investigates how online frame-of-reference (FOR) training of raters of the objective structured clinical examination (OSCE) for physical therapy students affects assessment accuracy.

Methods: The research was conducted in a 1-month-long randomized controlled trial.

Participants: The participants were 36 physical therapists without experience assessing clinical skills using the OSCE. The training group completed the FOR training online, which was conducted once a week in two 90-minute sessions. The control group self-studied the rubric rating chart used in the assessment. As a measure of accuracy, weighted kappa coefficients were used to check the agreement between correct score and those assessment by the participant in the OSCE.

Results: The scores of the training group were higher than those of the control group in both post- and follow-up assessments, showing significant differences. No significant difference was found based on the assessment time and group for the high-agreement groups. Furthermore, scores of the low-accuracy training group were higher in the post- and follow-up assessments than those in the pre-assessment, showing significant differences.

Conclusions: Online FOR training of the raters of the OSCE for physical therapists improved the assessment accuracy of the raters who had low accuracy in the pre-assessment; this improvement was maintained.

Objective: This study aimed to analyze the relationship between frailty in older patients with diabetes and audiovisual senses.

Methods: The survey included (1) basic attributes, (2) diabetes-related items, (3) frailty, evaluated according to the Obu Study of Health Promotion for the Elderly (OSHPE) standard, and (4) audiovisual function. Participants included 157 diabetes patients aged ≥65 years, divided into three groups: robust health (n=50), pre-frail (n=76), and frail (n=31). A simple regression analysis, in which the total OSHPE score was used as the dependent variable and the most relevant audiovisual items were used as independent variables, was performed to analyze the frailty factor. Next, a multiple regression analysis adjusted for age and sex was performed with total OSHPE score as the dependent variable and the items most relevant for audiovisual senses as independent variables.

Results: For the robust health, pre-frail, and frail groups, frequencies of hearing loss were 18.4%, 42.1%, and 35.5%, respectively, and were associated with frailty; visual impairment frequencies were 38%, 63.2%, and 58.1%, respectively. In multiple regression analysis, economic difficulties (B=0.349, β=0.172, p<0.05), absence of dyslipidemia (B=–0.494, β=–0.171, p<0.05), lower MNA score (B=–0.169, β=–0.214, p<0.05), and worsening hearing in the poor hearing ear (B=0.015, β=0.176, p<0.05) were significantly associated with frailty.

Conclusions: Hearing but not vision was associated with frailty in older patients with diabetes.

Background: The novel coronavirus disease (COVID-19) pandemic has no end in sight. Currently, the emphasis is on policies aimed at easing movement restrictions and maintaining socio-economic activities. However, infection control in psychiatric hospitals has been challenging. There have been reports on the impact on mental health and outpatient/inpatient treatment environments in the field of child psychiatry. An outbreak of COVID-19 was experienced in a child and adolescent psychiatric ward, and considering that there have been few similar reports, it was deemed meaningful to accumulate such experiences.

Case presentation: Three COVID-19-positive cases, all 14-year-old girls, were confirmed in a cluster among seven hospitalized patients in a child and adolescent psychiatric ward. Two patients presented symptoms of upper respiratory inflammation and one was asymptomatic. The main psychiatric diagnoses were post-traumatic stress disorder in one patient and autism spectrum disorder in the other two patients. The entire hospital ward was designated as a red zone (contaminated area), and infection control measures were adopted, such as halting group activities, wearing masks, and maintaining distance between patients. Additionally, it was necessary to use the infection control ward as it was difficult to ensure patient compliance.

Conclusion: Infection control in COVID-19 clusters at child and adolescent psychiatric wards is difficult due to patient characteristics and symptoms. Restricted activities and care also result in psychobehavioral consequences, regardless of infection status. To achieve both infection control and a better treatment environment, it is necessary to make careful preparations while learning from these experiences.
