Effectiveness of a web-based learning program for promoting local healthcare planning competencies.

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.

Comparison of water balance among healthy young and old adults and handicapped adults.

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.

Association between public health nurses' involvement in local healthcare planning and the corresponding off-the-job training.

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.

Necessity of daily 1000-IU vitamin D supplementation for maintaining a sufficient vitamin D status.

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.

Feasibility of an educational program for public health nurses to promote local healthcare planning: protocol for a pilot randomized controlled trial.

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).

Comparative accuracy of cervical cancer screening strategies in healthy asymptomatic women: a systematic review and network meta-analysis.

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.

Effects of daily 1,000-IU vitamin D-fortified milk intake on skeletal muscle mass, power, physical function and nutrition status in Japanese.

An intervention study was conducted to investigate the effects of daily 1,000-IU vitamin D-fortified milk intake on skeletal muscle mass, power, physical function and nutrition status in 26 healthy people and 8 older adults living in a nursing home. The serum 25-hydroxyvitamin D [25(OH)D] level was 13.4 ±â€…0.8 ng / mL and it markedly increased to 29.6 ±â€…0.9 ng / mL after daily 1000-IU vitamin D-fortified milk intake for 6 months. Handgrip strength (kg) also significantly increased in the 21-50 years and total groups, and male subjects, and the timed up and go test significantly improved in the 21-50 years and total groups, and female subjects after 6-month vitamin D intake. However, there were no significant differences between baseline and post-treatment in the Barthel Index (BI), walking speed (m / sec) or skeletal muscle mass (kg, % of BW, kg / m2). Therefore, the present study suggested that vitamin D-fortified milk intake is effective at improving muscle strength and physical function in Japanese, although further studies are needed, particularly for older adults.

[Factors associated with community collaboration in the implementation phase of the local health-care, medical, and welfare plan].

Objective　The 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.Methods　The 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.Results　A 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.Conclusion　From 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.

National Data Analysis and Systematic Review for Human Resources for Cervical Cancer Screening in Japan.

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.

Cut-off values for skeletal muscle strength and physical functions in Japanese elderly with walking difficulty.

Age-related changes in muscle strength and physical functions, and the association between vitamin D status and skeletal muscle functions were investigated in 36 men (21-90 years old) and 52 women (21-104 years old). Significant ageing-related decreases in several skeletal muscle functions and serum 25-hydroxyvitamin D [25(OH)D] levels were observed in both men and women. Cut-off values for the Timed up and go (TUG) test, walking speed, handgrip strength and Barthel Index (BI) detecting walking difficulties in the receiver operating characteristic (ROC) analysis were 11.1 sec, 0.60 m / sec, 17.0 kg, and 90.0 in males, and 28.6 sec, 0.43 m / sec, 13.9 kg, and 67.5 in females, respectively. By comparing personal present data of muscle strength with these cut-off values, people can easily understand their process to walking difficulty. Therefore, these results are important and useful to avoid or to delay a handicapped and dependent status by improving the vitamin D level, rehabilitation and nursing care. J. Med. Invest. 68 : 48-52, February, 2021.

Self-reported competences of public health nurses for developing needs-oriented local healthcare plans: A nationwide cross-sectional survey.

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.

Epidemiology: Pathogenesis, and Diagnostic Strategy of Diabetic Liver Disease in Japan.

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.

Relationship between age-related decreases in serum 25-hydroxyvitamin D levels and skeletal muscle mass in Japanese women.

A clearer understanding of skeletal muscle mass (SMM) in middle-aged and elderly individuals is important for maintaining functionality. In the present study, age-related changes in SMM, the threshold of SMM with walking difficulty, intestinal nutrient absorption rate, and various serum factors were examined in Japanese populations of different ages. We used 24-h creatinine excretion as a measure of total body SMM. Age-related decreases in SMM, intestinal nutrient absorption rates, and serum 25-hydroxyvitamin D [25(OH)D] concentrations were significantly higher in women than in men. The cut-off values for SMM (kg), its percentage of total body weight (BW), the SMM index [SMMI] (Kg / m2), and creatinine height index (CHI) (%) in elderly individuals with walking difficulty were approximately 8-10 kg, 17-20% of BW, 3.9-4.6 kg / m2, and 44%, respectively. Serum 25(OH)D concentrations were closely associated with SMM (kg, % of BW, kg / m2) and CHI (%) as well as the intestinal absorption rates of nitrogen (%) and phosphorus (%) in women, but not in men. The present results demonstrate that vitamin D is an important metabolic factor in skeletal muscle, and contributes to the optimal management of skeletal muscle and the prevention of sarcopenia. J. Med. Invest. 67 : 151-157, February, 2020.

Impact of web-based learning for health program planning competency, knowledge and skills among mid-level public health nurses: A randomized controlled trial.

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.

Low-Complexity and Hardware-Friendly H.265/HEVC Encoder for Vehicular Ad-Hoc Networks.

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.

Late evening snacks with branched-chain amino acids improve the Fischer ratio with patients liver cirrhosis at fasting in the next morning.

BACKGROUND & AIMS: A late evening snack (LES) is recommended as a nutritional therapy for liver cirrhosis to minimize early starvation. In patients with liver cirrhosis, the maintenance of the branched-chain amino acid (BCAA) levels is important during muscle synthesis at night. Therefore, we investigated the effects of a LES with BCAAs on the Fischer ratio in patients with liver cirrhosis. METHODS: This study included 10 outpatients with liver cirrhosis who did not consume a LES. Regarding the patient characteristics, the mean age was 73.1 ± 8.9 years, the male:female ratio was 5:5, and the mean body mass index was 23.3 ± 2.4 kg/m2. The etiology was hepatitis C virus in eight patients and alcoholism in two patients. Amino acid levels were measured in all 10 patients at four time points: before LES (control) and 1 month after the administration of each BCAA. The administration levels included 1) LES: BCAA-enriched enteral nutrition (BCAA-EN) containing BCAAs 6.1 g as a LES; 2) GP-no LES: BCAA-enriched granule product (BCAA-GP) containing 4 g BCAAs per pack, two packs per day, and BCAA-EN until dinner containing BCAAs in total 14.1 g per day; and 3) GP-LES: BCAA-GP, two packs per day, and BCAA-EN as a LES containing BCAAs in total 14.1 g per day. The Friedman nonparametric test with a post-hoc Dunn's multiple comparison was used for statistical analyses. RESULTS: There were no significant changes in body weight and serum albumin levels between the three types of BCAA administration. Valine significantly increased following LES and GP-LES, isoleucine significantly increased following GP-LES, and tyrosine significantly decreased following LES and GP-LES compared with those in the control. There was no significant difference in the leucine and phenylalanine levels among the groups. The Fischer ratio in the LES (2.2 ± 0.8) and GP-LES (2.3 ± 0.8) groups were significantly higher than that in the control (1.8 ± 0.6), but there was no significant difference compared with the Fischer ratio in the GP-no LES (1.8 ± 0.7) group. Furthermore, the Fischer ratio was significantly higher in the GP-LES group than in the GP-no LES group. CONCLUSION: These results suggested that it is not only the amount of BCAAs, but also LES with BCAAs, which is needed to improve the Fischer ratio at fasting.

Effectiveness of an educational program for mid-level Japanese public health nurses to improve program planning competencies: A preliminary randomized control trial.

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.

Quality-Oriented Perceptual HEVC Based on the Spatiotemporal Saliency Detection Model.

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.
