Improved Efficiency of the Clinical Diagnostic Criteria for Familial Hypercholesterolemia in Children: A Comparison of the Japan Atherosclerosis Society Guidelines of 2017 and 2022.

AIMS: Familial hypercholesterolemia (FH) is a genetic disorder characterized by elevated low-density lipoprotein cholesterol (LDL-C) levels, which increases the risk of premature coronary artery disease. Early detection and treatment are vital, especially in children. To improve FH diagnosis in children, the Japan Atherosclerosis Society (JAS) released new guidelines in July 2022. This study assessed and compared the sensitivity and specificity of the clinical diagnostic criteria from the JAS pediatric FH guidelines of 2017 and 2022. METHODS: From September 2020 to March 2023, 69 children with elevated plasma LDL-C levels (≥ 140 mg/dL) were included in a pediatric FH screening project in Kagawa. The children were evaluated using genetic testing alongside the clinical diagnostic criteria from the JAS pediatric FH guidelines of 2017 and 2022. RESULTS: Using the JAS pediatric FH 2017 criteria, eight children were diagnosed as FH-positive and 61 children as FH-negative. The JAS pediatric FH 2022 criteria identified 15 children with definite FH, 31 with probable FH, and 23 with possible FH. Genetic testing detected FH pathogenic variants in 24 children. The sensitivity and specificity for the JAS pediatric FH 2017 criteria were 0.292 and 0.978, respectively. For the JAS pediatric FH 2022 criteria, the sensitivity was 0.542 for definite FH with a specificity of 0.956, and 0.917 for probable FH with a specificity of 0.467. CONCLUSION: The clinical diagnostic criteria of the JAS pediatric FH 2022 guidelines demonstrated improved diagnostic efficiency compared with those of 2017, as evidenced by the increased sensitivity while preserving specificity.

[A survey on the utilization of internet services to collect job information among medical students and initiation of video public relations activities for the recruitment of public health physicians based on the survey results].

Objectives　It is difficult for medical students to obtain information about public health physicians because there are very few public health physicians near them. To improve this situation, we surveyed the utilization of internet services to collect job information among medical students and produced six videos and conducted public relations activities for the recruitment of public health physicians based on the survey results.Methods　The subjects of the survey were medical students in their third year or above from 18 universities. Public health teachers in these 18 universities sent their students anonymous self-administered questionnaires created with Google Forms mainly by e-mail. The questionnaires included the following items "internet services used to collect job information," "desired length of each video for knowing job information," and "information you want to know about your future work." The responses were reflected in the length and the content of the videos and the settings for their distribution.Results　Responses were obtained from a total of 491 medical students, including 14 third-year students, 177 fifth-year students, and 300 sixth-year students. Homepages were the most frequently used online source for collecting job information (94.7%), followed by blogs (42.0%), Twitter (32.6%), and YouTube (18.9%). Medical students are less likely to use social networking services for collecting job information compared with non-medical job-hunting students. Regarding the length of the videos, 55.8% of the respondents preferred the length of one video to be less than 5 minutes, and 95.1% preferred it to be less than 10 minutes. Almost all of the respondents (93.1%) wanted to know the atmosphere of young public health physicians, and 74.1% also wanted to know the atmosphere of veteran physicians. Based on these results, we selected six public health physicians including young and veteran physicians and produced interview videos that conveyed the atmosphere of each doctor within 5 minutes per person. We refurbished the banner on the top page of the Japanese Association of Public Health Center Directors so that the videos uploaded to YouTube could be watched.Conclusion　We clarified the current situation of the utilization of internet services for job-hunting activities among medical students and were able to initiate video public relations activities for the recruitment of public health physicians in accordance with the needs. It is necessary to increase awareness of the video platform among medical students and clinicians by deepening cooperation with local governments, universities, and medical institutions and expanding the human network both online and in person.

A Comparison of Sleep Duration Accuracy Between Questionnaire and Accelerometer in Middle Childhood.

Purpose Healthy sleep is vital to children's well-being, and assessing sleep efficiently and accurately can help understand children's lifestyles. Due to the difficulty in objectively measuring sleep duration using wearable sensors in large-scale surveys of children, self-administered questionnaires are often used in Japan; however, their accuracy is uncertain. We evaluated and compared the accuracy of questionnaire-based sleep times to those of wearable sensors. Methods This observational study was conducted between November 2019 and January 2020. A self-administered questionnaire on lifestyle habits and ActiGraph GT3X+ (ActiGraph, Inc., Pensacola, USA) accelerometer data were collected from 40 fourth-grade elementary school students in Kagawa Prefecture, Japan. We analyzed measurements for 256 days out of 280 days (40 persons × 7 days) after excluding days when the rate of wearing the accelerometer was < 90%. Results The median sleep duration per accelerometry was 453 minutes, and the median time in bed was 519 minutes. Questionnaire-based time in bed was 11 minutes longer, with relatively high inter-individual variability. The difference in bedtime was 26 minutes earlier, and wake-up time was 12 minutes earlier for the questionnaire. The average sleep efficiency was 87.4%, and one-third of the children had sleep efficiency < 85%. Conclusion The difference in sleep duration by questionnaire compared to accelerometry was approximately 10 minutes, suggesting the questionnaire may determine sleep duration with accuracy.

Universal Screening for Familial Hypercholesterolemia in Children in Kagawa, Japan.

AIM: Familial hypercholesterolemia (FH) is an underdiagnosed autosomal dominant genetic disorder characterized by high levels of plasma low-density lipoprotein cholesterol (LDL-C) from birth. This study aimed to assess the genetic identification of FH in children with high LDL-C levels who are identified in a universal pediatric FH screening in Kagawa, Japan. METHOD: In 2018 and 2019, 15,665 children aged 9 or 10 years underwent the universal lipid screening as part of the annual health checkups for the prevention of lifestyle-related diseases in the Kagawa prefecture. After excluding secondary hyper-LDL cholesterolemia at the local medical institutions, 67 children with LDL-C levels of ≥ 140 mg/dL underwent genetic testing to detect FH causative mutations at four designated hospitals. RESULTS: The LDL-C levels of 140 and 180 mg/dL in 15,665 children corresponded to the 96.3 and 99.7 percentile values, respectively. Among 67 children who underwent genetic testing, 41 had FH causative mutations (36 in the LDL-receptor, 4 in proprotein convertase subtilisin/kexin type 9, and 1 in apolipoprotein B). The area under the curve of receiver operating characteristic curve predicting the presence of FH causative mutation by LDL-C level was 0.705, and FH causative mutations were found in all children with LDL-C levels of ≥ 250 mg/dL. CONCLUSION: FH causative mutations were confirmed in almost 60% of the referred children, who were identified through the combination of the lipid universal screening as a part of the health checkup system and the exclusion of secondary hyper-LDL cholesterolemia at the local medical institutions.

Quality of dying and death desired by residents of Kagawa Prefecture, Japan: a qualitative study.

BACKGROUND: Achieving a desirable death is an urgent aging-related problem in Japan. However, measures of the quality of death and dying in Japan are lacking. This study aimed to identify components of a desirable death in the residents of Kagawa prefecture, Japan, through focus group interviews. METHODS: A group interview was conducted with 30 residents aged 20-80 (Mage = 50.9, SD = 22.1 years; 43.3% ≥ 65 years; 40.0% unemployed) who had experienced the death of a closely associated person. Participants were grouped into four generations with diverse characteristics (e.g., age, sex, occupation). The interview lasted 1-2 h and involved one interviewer, one observer, and one recorder. The interview theme was "What is a desirable death?" Participants were asked "What do you want to achieve before you die?" or "What would a close friend want to experience when death is near?" We then extracted important items related to "desirable death" using serialization and observation records, while also consulting three analysts. The analysis results of the four generations were ultimately integrated into final categories. RESULTS: The most common experience of a familiar death was that of parents, followed by grandparents. Half of participants had witnessed the death. Through category analysis, eight important categories related to desirable death were ultimately extracted. Nine items were identified as common to all generations. While the elderly generation had wide-ranging opinions, the younger generations' opinions tended to concentrate on satisfaction with life and family relations. CONCLUSION: Eight concepts were extracted as important factors of a desirable death from the residents of Kagawa prefecture, Japan.

Behavior problems and dysfunctional parenting: Cross-sectional study in Japan.

BACKGROUND: The Japanese government has established a law encouraging early detection and treatment of developmental disorders in children. Child behavior problems (CBP) tend to be recognized at school as a result of developmental disorders. The aim of this study was to identify factors associated with CBP in Japan. We hypothesized that factors other than developmental disorders are important in explaining CBP. METHODS: The study was conducted between February and March 2015. Parents of 3,515 children aged 2-5 years attending one of 34 public nursery schools in Takamatsu, Kagawa, Japan received self-administered questionnaires addressing parental socioeconomic factors, mental health, parenting style (i.e. hostile, overreactive, or lax), developmental disorders in children, and CBP. A multiple regression analysis was applied to explore associations between CBP and possible factors. RESULTS: Overall, 1,410 mothers were eligible to participate in the study. Children diagnosed with developmental disorders accounted for 7.8% of the sample, while on the Eyberg Child Behavior Inventory 17% of children had behavior problems needing clinical intervention. After adjustment for confounding factors, as well as for the diagnosis of developmental disorders, poor mental status and all three dysfunctional parenting styles had strong associations with CBP, and hostile, overreactive, and lax parenting had standardized ß-values (ß) of 0.29, 0.28, and 0.15, respectively (P < 0.01). A problematic relationship between the parents was also significantly associated with CBP (ß = -0.29, P < 0.01). CONCLUSION: When CBP are identified, parenting skills, mental health status and parental relationships should be considered along with the possibility of developmental disorders in the development of interventions.

Relationship Between Long-term Flooding and Serious Mental Illness After the 2011 Flood in Thailand.

OBJECTIVE: The present study aimed to evaluate the long-term psychological effects of the 2011 flood in Thailand on flood victims and unaffected residents, taking into account risk factors such as floodwater levels in the house, period of flooding, and disruption to essential services. METHODS: Surveys were conducted in Salaya and Nakhon Chaisri subdistrict, Nakhonpatom Province, from May to June 2012. Approximately 400 households were selected. Measures of sociodemographic variables, exposure to flooding, incidents (eg, disruption of services), and outcome variables (Kessler 10) were recorded. RESULTS: A total of 407 respondents completed the survey. The results of the univariate analysis showed that possible serious mental illness was approximately 1.5 times higher in flood victims than in unaffected respondents. After adjustment for potential confounding factors, significant associations were found for disruption of essential services and hypertension or diabetes with possible serious mental illness. CONCLUSIONS: Disruption of essential services and chronic illness may affect psychological distress among flood victims. Public health agencies should develop and evaluate strategies to improve risk communication and psychological support for flood victims. (Disaster Med Public Health Preparedness. 2017;11:300-304).

Sex differences in attachment to spouses among older Japanese couples.

AIM: Attachment among older adults can partially explain sex differences in bereavement outcomes, but there is currently little evidence regarding this. The aim was to quantify sex differences in the proportion of spouses as attachment figures among older couples. METHODS: We carried out a secondary analysis of cross-sectional questionnaire survey data. The dataset included information about 5137 respondents aged 65 years or older in Kanonji and Mitoyo, two rural cities in Kagawa prefecture, Japan; those who were never married or were widowed or divorced were excluded. The questionnaire asked participants whom they most want to be close by when they die (this person was defined as an "attachment figure"), and compared the proportion of older people of each sex who named their spouse. We used multiple logistic regression analyses to examine the independent association of sex with the proportion of spouses as attachment figures. RESULTS: Of the 2513 male respondents, 1494 (59.5%) answered "spouse." Of the 2624 female respondents, 904 (34.5%) answered "spouse." Multiple logistic regression analyses adjusted for age, live-in children, annual income, participation in community activities, presence of a long-term primary care doctor, anxiety about death and preferences for place of death showed that men had a higher probability of attachment to spouses than women (odds ratio 2.83, 95% confidence interval 2.43-3.31). CONCLUSIONS: Spouses are more likely to be attachment figures for men than for women. The present study supports the theory that sex differences in attachment might partially explain the differences in the bereavement effect between sexes among older people.

Effort-reward imbalance and low back pain among eldercare workers in nursing homes: a cross-sectional study in Kagawa Prefecture, Japan.

OBJECTIVES: To clarify effort-reward imbalance among eldercare workers in nursing homes and to examine the association between the effort-reward imbalance (ERI) and low back pain (LBP) among them. METHODS: A total of 549 questionnaires were distributed to a random sample comprising 23% of the 79 special elderly nursing homes in Kagawa in 2013. A total of 467 eldercare workers (response rate 85%) participated in this study. Of the 467 eligible respondents, 372 (80%) completed all items of the ERI questionnaire. Complete data were available for 342 (73%) eldercare workers. RESULTS: Of the 342 respondents, 215 (63%) had LBP at the time of the study, and 291 (85%) showed a critical "high cost/low gain" condition as determined by an effort-reward ratio >1. Multiple logistic regression analyses adjusted for age, gender, previous LBP experience, high-risk work and K6 score showed that eldercare workers with a high ERI had a higher risk for LBP than workers with a low ERI (OR, 1.96; 95% CI, 1.02-3.77). CONCLUSIONS: Most eldercare workers have a high ERI, and their LBP is associated with their ERI. Balancing effort and reward may be an important factor for improving LBP among eldercare workers in nursing homes.
