RESUMO
OBJECTIVE: To determine the effectiveness of a web-based educational program regarding local healthcare planning by public health nurses (PHNs) in Japan. DESIGN: A single-blind randomized controlled trial. SAMPLE: Full-time PHNs working for local governments across Japan. MEASUREMENTS: The primary outcome was nurses' self-perception of competencies in public health policy. The secondary outcome was self-perception of knowledge, skills, and perspectives regarding local healthcare planning. We analyzed intergroup differences using the intention-to-treat principle and the Mann-Whitney U-test. INTERVENTION: The intervention group received six web-based learning modules including substantial knowledge and skills regarding local healthcare planning based on the analysis, design, development, implementation, and evaluation model and adult learning theory. RESULTS: Totally, 273 PHNs registered, and 38 were excluded without completing the baseline survey; 235 were randomly allocated to either the intervention (n = 118) or control (n = 117) groups. Sixty-four participants in the intervention group completed the program. Over 70% of the participants lacked opportunities to learn about local healthcare planning. The intervention group showed significant improvement in self-perception of competencies, knowledge, and skills regarding local healthcare planning, except for items related to evaluation. CONCLUSIONS: The web-based learning program effectively improved participants' self-perception of competencies in local healthcare planning.

AIM: To identify self-reported competencies of public health nurses for reflecting community healthcare needs in local healthcare plans. DESIGN: We conducted a nationwide cross-sectional survey in Japan from October 7-November 30, 2019. METHODS: We sent 2,185 self-reported questionnaires to public health nurses in Japan who had developed a local healthcare plan since 2013. Self-reported questionnaires included questions regarding demographic data and the reflection of community healthcare needs in local healthcare plans, and the involvement in local healthcare planning. RESULTS: We analysed 1,042 questionnaires: 651 (62.5%) were from public health nurses who reported that they elicited and shared community views to be reflected for purposes of local healthcare planning (the reflecting group), and 391 (37.5%) of the remaining public health nurses who reported that they did not do so (the non-reflecting group). The logistic regression analysis revealed that public health nurses in the reflecting group were more likely to be in a managerial position, have colleagues who played an active role in healthcare planning, conduct a questionnaire survey, engage in group work, participate in a municipal healthcare planning committee with community-dwelling people, and identify the opinions of the professional organizations. CONCLUSIONS: Identifying community healthcare needs through collaboration with community-dwelling people and professional organizations should be essential competencies for public health nurses (the reflecting group) in developing needs-oriented local healthcare plans. IMPACT: Identification of their related competencies for developing a needs-oriented local healthcare plan as an upstream strategy to mitigate the prevalence of health inequities in each community.

ObjectiveãThe aim of this study was to elucidate the status of health-care, medical, and welfare planning (hereafter, "planning")-in which public health nurses (PHNs) had participated-and the factors associated with community collaboration in the implementation phase. Additionally, suggestions regarding health activities that would contribute to improving the entire community's health level were obtained.MethodsãThe Plan-Do-Check-Act (PDCA) cycle was the conceptual framework for this study, and the focus was the implementation phase of the plan (i.e., corresponding to the "Do" phase). Survey items were part of the "Plan" phase and identified the extent to which PHNs collaborated with community-dwellers in implementation, their demographics, their participation in the planning process, organizational factors, and the strategies used in the planning phase. The participants were full-time PHNs working in local governments who had participated in the planning process since 2013 (when the guidelines for PHNs' practices were published). A nationwide, cross-sectional survey was conducted in Japan with 2,185 PHNs from 220 regions (36 prefectures, 41 cities with public health centers, and 153 municipalities) who expressed the willingness to participate in this study. A binomial logistic regression analysis was conducted to examine the association between community collaboration and the independent variables.ResultsãA total of 1,281 answers (a 58.6% response rate) were received. Ultimately, 1,028 (a 47.0% valid response rate) were analyzed; exclusions were 203 for no experience in health care planning since 2013 and 50 with missing values. There were 125 (12.2%) PHNs who answered that they "did not collaborate with the community-dwellers at all," 293 (28.5%) who answered that they "did not collaborate with them much," 482 (46.9%) who replied that they "collaborated with them a little," and 128 (12.4%) who responded that they "collaborated with them a lot." The binomial logistic regression analysis showed that the following were associated with PHNs' collaboration with the community: being in a managerial position, having experience developing a health promotion plan, conducting a questionnaire survey or group work, as well as participating in municipal health planning committees with community-dwellers, utilizing research evidence, identifying target groups, and managing the plan's progress.ConclusionãFrom the planning phase, PHNs must collaborate with community residents and reflect their voices so that the formulated plan will help resolve medium to long-term issues in the community related to health and life.

Type 2 diabetes (T2D) is closely associated with nonalcoholic fatty liver disease (NAFLD). Nonalcoholic steatohepatitis (NASH), a severe form of NAFLD, can lead to cirrhosis, hepatocellular carcinoma (HCC), and hepatic decompensation. Patients with T2D have twice the risk of HCC incidence compared with those without T2D. Because the hepatic fibrosis grade is the main determinant of mortality in patients with NAFLD, identifying patients with advanced fibrosis using non-invasive tests (NITs) or imaging modalities is crucial. Globally, the fibrosis-4 index (FIB-4 index), NAFLD fibrosis score, and enhanced liver fibrosis test have been established to evaluate hepatic fibrosis. Two-step algorithms using FIB-4 index as first triaging tool are globally accepted. It remains unknown which kinds of NITs or elastography are best as the second step tool. In Japan, type IV collagen 7s or the CA-fibrosis index (comprising type IV collagen 7s and aspartate aminotransferase (AST)) is believed to precisely predict advanced fibrosis in NAFLD. Patients with NAFLD who have high non-invasive test results should be screened for HCC or esophageal varices. Risk factors of rapid fibrosis progression in NAFLD includes age, severe obesity, presence of T2D, menopause in women, and a patatin-like phospholipase domain containing the 3 GG genotype. Patients with NAFLD who have these risk factors should be intensively treated with lifestyle modification or pharmacotherapies for preventing liver-related mortality.

Real-time video streaming over vehicular ad-hoc networks (VANETs) has been considered as a critical challenge for road safety applications. The purpose of this paper is to reduce the computation complexity of high efficiency video coding (HEVC) encoder for VANETs. Based on a novel spatiotemporal neighborhood set, firstly the coding tree unit depth decision algorithm is presented by controlling the depth search range. Secondly, a Bayesian classifier is used for the prediction unit decision for inter-prediction, and prior probability value is calculated by Gibbs Random Field model. Simulation results show that the overall algorithm can significantly reduce encoding time with a reasonably low loss in encoding efficiency. Compared to HEVC reference software HM16.0, the encoding time is reduced by up to 63.96%, while the Bjontegaard delta bit-rate is increased by only 0.76-0.80% on average. Moreover, the proposed HEVC encoder is low-complexity and hardware-friendly for video codecs that reside on mobile vehicles for VANETs.
RESUMO
OBJECTIVES: To evaluate the impact of web-based learning modules for health program planning competency, recognition, knowledge and skills among mid-level public health nurses (PHNs). DESIGN: Parallel-group randomized controlled trial. SAMPLE: During 2018, 244 Japanese PHNs were eligible as participants with 5-20 years experiences as a PHN were randomly allocated to the intervention (n = 121) or control group (n = 123). MEASUREMENTS: The outcome was assessed using the Competency Measurement of Creativity for PHNs (CMC) and 26 questions about recognition, knowledge, and skills for health program planning. INTERVENTIONS: Eight web-based modules. RESULTS: No significant differences in CMC scores between the control and intervention groups at base line and post-intervention. By contrast, significant differences in total score of the 26 items of knowledge and skills. In an exploratory analysis, there was a significant difference identified in CMC scores in the demographic of post graduate training in program planning at base line and post-intervention. (p = .034). CONCLUSIONS: The findings suggested that web-based learning with flexibility in terms of time and location would improve competency, skills and knowledge of health program planning among mid-level PHNs.

OBJECTIVE: To evaluate the effectiveness of an education program for mid-level Japanese public health nurses (PHNs) to improve their competencies in program planning, which will fulfill community health needs. DESIGN: Randomized control trial. SAMPLE: During 2017, 103 PHNs with 5-20 years of PHN work experience in Japan were enrolled and randomly allocated to the intervention (n = 51) or control group (n = 52). MEASUREMENTS: The primary outcome measured competency in program planning based on Competency Measurement of Creativity for PHNs (CMC), knowledge, and skills regarding program planning. INTERVENTION: Six web-based learning modules followed by two face-to-face group sessions. RESULTS: The PHN participants averaged about 12 years of experience. In the intervention group, 25 PHNs completed all modules (49.0%). Post intervention, there were no statistically significant differences among any between-group CMC scores. However, the intervention group's CMC 3 score was significantly higher than that of the control group of ≥12 years of experience. Total knowledge and skill scores also improved significantly in the intervention group compared with the control group. CONCLUSIONS: The results suggest that PHNs with ≥12 years of experience are a suitable target of this educational program, and should play a key role in program planning.

Perceptual video coding (PVC) can provide a lower bitrate with the same visual quality compared with traditional H.265/high efficiency video coding (HEVC). In this work, a novel H.265/HEVC-compliant PVC framework is proposed based on the video saliency model. Firstly, both an effective and efficient spatiotemporal saliency model is used to generate a video saliency map. Secondly, a perceptual coding scheme is developed based on the saliency map. A saliency-based quantization control algorithm is proposed to reduce the bitrate. Finally, the simulation results demonstrate that the proposed perceptual coding scheme shows its superiority in objective and subjective tests, achieving up to a 9.46% bitrate reduction with negligible subjective and objective quality loss. The advantage of the proposed method is the high quality adapted for a high-definition video application.
RESUMO
The Bethesda system (TBS) has been used for cervical cytological diagnosis in Japan since 2008. Evaluation of specimen adequacy is the most important aspect of quality assurance and for precise diagnosis in TBS. A systematic review and meta-analysis were carried out to assess the unsatisfactory specimen rate in the primary cervical cancer screening setting in Japan. Ovid Medline and Ichushi-Web databases were searched from inception through to May 2017. Prospective and retrospective studies that reported the proportion of unsatisfactory specimens in healthy asymptomatic Japanese women in a cervical cancer screening program were eligible for inclusion; 17 studies were included in the meta-analysis. The random-effects model meta-analysis calculated summary estimates of the unsatisfactory rate of 0.60% (95% confidence interval [CI], 0.18-1.96%; I2 = 99%) for conventional cytology and 0.04% (95% CI, 0.00-0.35%; I2 = 99%) for liquid-based cytology (LBC). However, comparative results between conventional and liquid-based cytology, based on four direct and nine comparative studies, showed no significant difference (summary odds ratio = 3.5 × 10-2 favoring LBC [95% CI, 6.9 × 10-4 -1.7]; I2 = 98%). In the subgroup analyses and meta-regressions, use of non-cotton devices for conventional cytology and use of a particular platform for LBC were associated with lower unsatisfactory rates. Meta-regression also suggested chronological improvement in unsatisfactory rates for both tests. In Japanese cervical cancer screening programs, conventional cytology remains prevalent. Future research needs to focus on evaluating the impact of screening programs using LBC by comparing the accuracy, performance, and cost-effectiveness with conventional cytology in the Japanese population.

BACKGROUND: Developing health services is a key strategy for improving the community health provided by public health nurses. However, an effective educational program for improving their skills in planning such services has not been developed. To describe our program and its evaluation protocol for the education of middle-level public health nurses to improve their skills in developing new health services to fulfil community health needs in Japan. METHODS: In this randomized control trial, eligible participants in Japan will be randomly allocated to an intervention group and a control wait-list group. We will provide 8 modules of web-based learning for public health nurses from July to October 2018. To ensure fairness of educational opportunity, the wait-list group will participate in the same program as the intervention group after collection of follow-up data of the intervention group. The primary outcomes will be evaluated using the scale of competency measurement of creativity for public health nurses at baseline, immediately after the intervention. Secondary outcomes will be knowledge and performance regarding program development of public health nurses. DISCUSSION: This study will enable the analysis of the effects of the educational program on public health nurses for improving their competency to develop new health services for fulfilling community health needs and enriching health care systems. TRIAL REGISTRATION: We registered our study protocol to the University hospital Medical Information Network- Clinical Trials Registry approved by International Committee of Medical Journal Editors (No. UMIN000032176, April, 2018).
RESUMO
OBJECTIVE: The incidence of breast cancer has progressively increased, making it the leading cause of cancer deaths in Japan. Breast cancer accounts for 20.4% of all new cancers with a reported age-standardized rate of 63.6 per 100 000 women. METHODS: The Japanese guidelines for breast cancer screening were developed based on a previously established method. The efficacies of mammography with and without clinical breast examination, clinical breast examination and ultrasonography with and without mammography were evaluated. Based on the balance of the benefits and harms, recommendations for population-based and opportunistic screenings were formulated. RESULTS: Five randomized controlled trials of mammographic screening without clinical breast examination were identified for mortality reduction from breast cancer. The overall relative risk for women aged 40-74 years was 0.75 (95% CI: 0.67-0.83). Three randomized controlled trials of mammographic screening with clinical breast examination served as eligible evidence for mortality reduction from breast cancer. The overall relative risk for women aged 40-64 years was 0.87 (95% confidence interval: 0.77-0.98). The major harms of mammographic screening were radiation exposure, false-positive cases and overdiagnosis. Although two case-control studies evaluating mortality reduction from breast cancer were found for clinical breast examination, there was no study assessing the effectiveness of ultrasonography for breast cancer screening. CONCLUSIONS: Mammographic screening without clinical breast examination for women aged 40-74 years and with clinical breast examination for women aged 40-64 years is recommended for population-based and opportunistic screenings. Clinical breast examination and ultrasonography are not recommended for population-based screening because of insufficient evidence regarding their effectiveness.

Mammographic screening with clinical breast examination has been recommended in Japan since 2000. Although mammographic screening without clinical breast examination has not been recommended, its introduction is anticipated. The efficacies of mammographic screening with and without clinical breast examination were evaluated based on the results of randomized controlled trials. PubMed and other databases for studies published between 1985 and 2014 were searched. The study design was limited to randomized controlled trials to evaluate mortality reduction from breast cancer. Five studies were eligible for meta-analysis of mammographic screening without clinical breast examination. The relative risk for women aged 40-74 years was 0.75 (95% confidence interval, 0.67-0.83). Three studies evaluated the efficacy of mammographic screening with clinical breast examination. The relative risk for women aged 40-64 years was 0.87 (95% confidence interval, 0.77-0.98). The number needed to invite was always lower in mammographic screening without clinical breast examination than in mammographic screening with clinical breast examination. In both screening methods, the number needed to invite was higher in women aged 40-49 years than in women aged 50-70 years. These results suggest that mammographic screening without clinical breast examination can afford higher benefits to women aged 50 years and over. Although evidence of the efficacy of mammographic screening without clinical breast examination was confirmed based on the results of the randomized controlled trials, a Japanese study is needed to resolve local problems.

OBJECTIVE: To examine the effects of lunches with different dietary energy densities on food preferences between genders. DESIGN: Randomized crossover study. Participants were administered the following packed test meals once weekly on a specified day during six sessions: control (150 g of rice with a sautéed beef entrée containing 40 g of raw beef and 240 g of vegetables), high-meat/low-rice, low-vegetable, medium-fat/low-vegetable, high-fat and high-fat/low-vegetable meals. Subjective levels of sensory properties were assessed over time using visual analogue scales. SETTING: University of Tokushima Graduate School, Tokushima, Japan. SUBJECTS: Sixty-five men and sixty-five women matched by age and BMI. RESULTS: Men showed significantly stronger desires for salty and fatty foods after meals (P<0.05). Women showed a significantly stronger desire for sweetness from 2 h after the low-vegetable meal, and increasing fat content under high-vegetable conditions caused a significant stimulated sweetness desire in women more than in men (P<0.05). Moreover, after a high-meat/low-rice meal with 100 g of rice, sweetness desire was stronger in women (P=0.024), whereas no significant differences in sweetness desire were shown between genders after another low-energy-density control meal with 150 g of rice. CONCLUSIONS: Men had significantly stronger desires for salty and fatty foods, whereas women preferred sweet food after meals. The sweetness desire in women was stimulated by increasing fat content, even with a high vegetable intake. Low rice intake in a low-energy-density diet also caused a relative stimulation of sweetness desire in women.

The isomaltulose based liquid formula (MHN-01), suppresses postprandial plasma glucose and insulin levels in healthy persons and patients with impaired glucose tolerance (IGT) or type 2 diabetes. MHN-01 intake as a part of breakfast also suppresses glucose and insulin levels after lunch, suggesting second meal effect. The objective of this study was to investigate the effects of nutritional counseling and long-term (24 weeks) MHN-01 ingestion on biomarkers of metabolic syndrome. Forty-one subjects with criteria of metabolic syndrome participated in this study composed with the control period (0-12 week) followed by nutritional counseling and the experimental period (12-36 week) followed by 200 kcal (837 kJ) of MHN-01 or dextrin-based standard balanced liquid formula (SBF) loading as a part of breakfast. In 16 of 41 subjects became to out of criteria for liquid formula loading study during control period (unqualified group). In the unqualified group, several biomarkers were improved. In experimental period, serum HbA1c levels significantly increased in SBF group (n = 12) but did not change in MHN-01 group (n = 10). Thus, intake of 837 kJ MHN-01 as a part of breakfast may be effective for suppression of deteriorating glucose metabolism in metabolic syndrome.
RESUMO
OBJECTIVE: This study investigated the association between receiving off-the-job training and the involvement of public health nurses in local healthcare planning. DESIGN: A nationwide, cross-sectional study design. METHODS: We sent self-report questionnaires to 2,185 public health nurses with experience in developing local healthcare plans in Japan since 2013 and collected information related to three main categories: demographic data, involvement in local healthcare planning and strategies for healthcare planning. RESULTS: We received 1,281 responses (return rate of 58.6%), of which 231 did not meet the inclusion criteria. Thus, we analysed 1,050 valid responses. Among the 1,050 respondents, 496 (47.2%) had received off-the-job training in healthcare planning. A subsequent logistic regression analysis revealed that the following factors were associated with this achievement: holding a managerial position, receiving healthcare planning education at the undergraduate level, having mentors regarding the promotion of it, partially conducting cross-sectional coordination and conducting groupwork with community-dwelling residents.

The body's water balance is changed by food and beverage intake, metabolism, and excretion. In this study, we performed a cross-sectional study that investigated the changes of water intake and water output in healthy Japanese young and elderly people and handicapped adults. Water balance was assessed by water intake from foods and beverages, metabolic water production, non-renal water losses (NRWL), and urine volume. Most of the parameters did not change with aging in healthy adults. Estimated total water intake (ml/kg/day) increased with aging. In the healthy men, healthy women, and handicapped adults, daily water intake (median [interquartile range]) accounted for 49.4 (41.4-59.9) ml/kg, 42.9 (38.7-51.8) ml/kg, and 50.9 (43.8-74.0) ml/kg, respectively. Water loss from the kidney accounted for 19.2 (16.2-29.2) ml/kg, 22.0 (16.2-26.6) ml/kg, and 27.5 (22.7-47.2) ml/kg, respectively. NRWL accounted for 26.6 (18.5-35.2) ml/kg, 22.4 (16.2-28.8) ml/kg, and 23.5 (19.8-28.5) ml/kg, respectively. Our findings suggest that a daily total water intake of more than 50-55 ml/kg is required to prevent dehydration in healthy and handicapped adults. J. Med. Invest. 70 : 195-199, February, 2023.

To compare all available accuracy data on screening strategies for identifying cervical intraepithelial neoplasia grade ≥ 2 in healthy asymptomatic women, we performed a systematic review and network meta-analysis. MEDLINE and EMBASE were searched up to October 2020 for paired-design studies of cytology and testing for high-risk genotypes of human papillomavirus (hrHPV). The methods used included a duplicate assessment of eligibility, double extraction of quantitative data, validity assessment, random-effects network meta-analysis of test accuracy, and GRADE rating. Twenty-seven prospective studies (185,269 subjects) were included. The combination of cytology (atypical squamous cells of undetermined significance or higher grades) and hrHPV testing (excepting genotyping for HPV 16 or 18 [HPV16/18]) with the either-positive criterion (OR rule) was the most sensitive/least specific, whereas the same combination with the both-positive criterion (AND rule) was the most specific/least sensitive. Compared with standalone cytology, non-HPV16/18 hrHPV assays were more sensitive/less specific. Two algorithms proposed for primary cytological testing or primary hrHPV testing were ranked in the middle as more sensitive/less specific than standalone cytology and the AND rule combinations but more specific/less sensitive than standalone hrHPV testing and the OR rule combination. Further research is needed to assess these results in population-relevant outcomes at the program level.

BACKGROUND: Promoting of local healthcare planning is crucial for assisting public health nurses in improving community health inequities. However, there is no effective educational program for developing relevant skills and knowledge among these nurses. Therefore, this study aims to assess the feasibility of a newly developed web-based self-learning program to promote the involvement of public health nurses in the local healthcare planning process. METHODS: A pilot randomized control trial randomly allocated eligible public health nurses to intervention and control wait-list groups [1:1]. The former will be exposed to six web-based learning modules from July to October 2021. After collecting post-test data, the wait-list group will be exposed to the same modules to ensure learning equity. The primary outcome will be evaluated by implementing a validated and standardized scale designed to measure public health policy competencies at the baseline and post-intervention, while secondary outcome will be measured on an action scale to demonstrate the necessity of healthcare activities. The third outcome will be the knowledge and skills related to local healthcare planning by public health nurses. The participants will provide feedback through free descriptions on the trial feasibility and a web-based self-learning program to identify improvement points for continual refinement. DISCUSSION: The results will provide suggestions in preparation for a future definitive randomized controlled trial. This will provide preliminary data for an intervention aimed at improving relevant competencies among public health nurses who are tasked with resolving health inequities in their respective communities through local health planning. TRIAL REGISTRATION: The protocol for this study was registered with the University Hospital Medical Information Network Clinical Trials Registry and approved by the International Committee of Medical Journal Editors (No. UMIN000043628 , March 23, 2021).
RESUMO
The changes in the serum 25-hydroxyvitamin D (25(OH)D) concentrations after daily 1000-IU vitamin D intake for 3 months (3-month-VD), 6 months (6-month-VD) and then 6-month cessation of vitamin D in-take (6-month-VD cessation) were examined. The serum 25(OH)D levels in 11 male and 16 female subjects were 12.1±3.5 ng/mL at baseline, increased to 27.1±4.7 ng/mL at 3-month-VD, 28.5±5.1 ng/mL at 6-month-VD and decreased to 16.4±4.0 ng/mL at 6-month-VD cessation. The present study suggested that a vitamin D intake of 1000 IU/day is required to maintain the 25(OH) D concentration at 30 ng/mL or higher without vitamin D intoxication. J. Med. Invest. 69 : 135-140, February, 2022.

BACKGROUND: Although cervical cancer screening has been performed as a national program since 1983 in Japan, the participation rate has remained below 20%. Equity of access is a basic requirement for cancer screening. However, taking smears from the cervix has been limited to gynecologists or obstetricians in Japan and it might be a barrier for accessibility. We examined the current access and its available human resources for cervical cancer screening in Japan. METHODS: We analyzed the number of gynecologists and obstetricians among 47 prefectures based on a national survey. A systematic review was performed to clarify disparity and use of human resources in cervical cancer screening, diagnosis, and treatment for cervical cancers in Japan. Candidate literature was searched using Ovid-MEDLINE and Ichushi-Web until the end of January 2020. Then, a systematic review regarding accessibility to cervical cancer screening was performed. The results of the selected articles were summarized in the tables. RESULTS: Although the total number of all physicians in Japan increased from 1996 to 2016, the proportion of gynecologists and obstetricians has remained at approximately 5% over the last 2 decades. 43.6% of municipalities have no gynecologists and obstetricians in 2016. Through a systematic review, 4 English articles and 1 Japanese article were selected. From these 5 articles, the association between human resources and participation rates in cervical cancer screening was examined in 2 articles. CONCLUSIONS: The human resources for taking smears for cervical cancer screening has remained insufficient with a huge disparity among municipalities in Japan. To improve accessibility for cervical cancer screening another option which may be considered could be involving general physicians as potential smear takers.
