Paternal involvement in infant care and developmental milestone outcomes at age 3 years: the Japan Environment and Children's Study (JECS).

BACKGROUND: In developed countries, the time fathers spend on childcare has increased steadily in recent decades. However, studies on the relationship between paternal care and child outcomes remain scarce. Thus, we examined the association between paternal involvement in childcare and children's developmental outcomes. METHODS: We used Japan's largest birth cohort data, the Japan Environment and Children's Study, to examine the relationship between paternal involvement in childcare at the child's age of 6 months and developmental milestone outcomes at the child's age of 3 years (n = 28,050). Developmental delays were assessed with Ages and Stages Questionnaire. Potential mediation by maternal parenting stress at the child's age of 1.5 years was also examined. We used log-binomial regression analyses to estimate risk ratios. RESULTS: Fathers' high involvement in childcare was associated with a lower risk of developmental delay in gross-motor, fine-motor, problem solving, and personal-social domains compared with low involvement, adjusting for potential confounders. For example, the risk ratio with 95% confidence intervals was 0.76 [0.67, 0.86] for the gross-motor domain. We also observed that the associations were partially mediated by maternal parenting stress. CONCLUSIONS: Fathers' active involvement in childcare during infancy may promote young children's development, partially by reducing maternal parenting stress. IMPACT: Using Japan's largest birth cohort data (Japan Environment and Children's Study), we showed that paternal involvement in infant care might benefit young children's development. Fathers' active involvement in infant care was associated with a lower risk of developmental delays in gross-motor, fine-motor, problem solving, and personal-social domains. Maternal parenting stress may mediate the association between paternal involvement in infant care and child development outcomes at 3 years.

Scoping Review of Screening and Assessment Tools for Social Determinants of Health in the Field of Cardiovascular Disease.

BACKGROUND: Despite the importance of implementing the concept of social determinants of health (SDOH) in the clinical practice of cardiovascular disease (CVD), the tools available to assess SDOH have not been systematically investigated. We conducted a scoping review for tools to assess SDOH and comprehensively evaluated how these tools could be applied in the field of CVD.Methods and Results: We conducted a systematic literature search of PubMed and Embase databases on July 25, 2023. Studies that evaluated an SDOH screening tool with CVD as an outcome or those that explicitly sampled or included participants based on their having CVD were eligible for inclusion. In addition, studies had to have focused on at least one SDOH domain defined by Healthy People 2030. After screening 1984 articles, 58 articles that evaluated 41 distinct screening tools were selected. Of the 58 articles, 39 (67.2%) targeted populations with CVD, whereas 16 (27.6%) evaluated CVD outcome in non-CVD populations. Three (5.2%) compared SDOH differences between CVD and non-CVD populations. Of 41 screening tools, 24 evaluated multiple SDOH domains and 17 evaluated only 1 domain. CONCLUSIONS: Our review revealed recent interest in SDOH in the field of CVD, with many useful screening tools that can evaluate SDOH. Future studies are needed to clarify the importance of the intervention in SDOH regarding CVD.

Incidence and predictors of ventilator-associated pneumonia using a competing risk analysis: a single-center prospective cohort study in Egypt.

BACKGROUND: Ventilator-associated pneumonia (VAP) is a challenging nosocomial problem in low- and middle-income countries (LMICs) that face barriers to healthcare delivery and resource availability. This study aimed to examine the incidence and predictors of VAP in Egypt as an example of an LMIC while considering death as a competing event. METHODS: The study included patients aged ≥ 18 years who underwent mechanical ventilation (MV) in an intensive care unit (ICU) at a tertiary care, university hospital in Egypt between May 2020 and January 2023. We excluded patients who died or were transferred from the ICU within 48 h of admission. We determined the VAP incidence based on clinical suspicion, radiological findings, and positive lower respiratory tract microbiological cultures. The multivariate Fine-Gray subdistribution hazard model was used to examine the predictors of VAP while considering death as a competing event. RESULTS: Overall, 315 patients were included in this analysis. Sixty-two patients (19.7%) developed VAP (17.1 per 1000 ventilator days). The Fine-Gray subdistribution hazard model, after adjustment for potential confounders, revealed that emergency surgery (subdistribution hazard ratio [SHR]: 2.11, 95% confidence interval [CI]: 1.25-3.56), reintubation (SHR: 3.74, 95% CI: 2.23-6.28), blood transfusion (SHR: 2.23, 95% CI: 1.32-3.75), and increased duration of MV (SHR: 1.04, 95% CI: 1.03-1.06) were independent risk factors for VAP development. However, the new use of corticosteroids was not associated with VAP development (SHR: 0.94, 95% CI: 0.56-1.57). Klebsiella pneumoniae was the most common causative microorganism, followed by Pseudomonas aeruginosa. CONCLUSION: The incidence of VAP in Egypt was high, even in the ICU at a university hospital. Emergency surgery, reintubation, blood transfusion, and increased duration of MV were independently associated with VAP. Robust antimicrobial stewardship and infection control strategies are urgently needed in Egypt.

Prenatal risk factors of indoor environment and incidence of childhood eczema in the Japan Environment and Children's Study.

The quality of indoor environment is a risk factor for early childhood eczema and atopic dermatitis; however, its influence during pregnancy on childhood eczema in Japan has not been investigated. In this study, we aimed to determine the indoor environmental factors that are associated with eczema in children up to 3 years of age, using national birth cohort data from the Japan Environment and Children's Study (JECS). Information on indoor environments and eczema symptoms until 3 years of age was collected using self-administered questionnaires to the mothers. A total of 71,883 and 58,639 mother-child pairs at 1.5- and 3-years-old, respectively, were included in the former analyses. To account for prenatal indoor risk factors, 17,568 (1.5-years-old) and 7063 (3-years-old) children without indoor mold and/or ETS exposure were included in the final analysis. A higher mold index, gas heater use, parquet flooring use, and frequent insecticide use showed significantly increased risks for childhood eczema up to 3 years of age. These associations were consistent after stratification analysis among children whose parents did not have a history of allergies. The updated WHO guidelines on indoor air quality should be implemented based on recent findings regarding the effects of prenatal exposure to indoor dampness on health effects of children further in life, including asthma, respiratory effects, eczema, and other immunological effects.

Regional Variation in End-of-Life Care just before Death among the oldest old in Japan : A descriptive study.

BACKGROUND: The use of life-sustaining treatment (LST) in the final stage of life is a major policy concern due to increased costs, while its intensity does not correlate with quality. Previous reports have shown declining trends in LST use in Japan. However, regional practice variations remain unclear. This study aims to describe regional variations in LST use before death among the oldest old in Japan. METHODS: A descriptive study was conducted among patients aged 85 or older who passed away between April 2013 and March 2014. The study utilized health insurance claims from Japan's National Database (NDB) to examine the use of cardiopulmonary resuscitation (CPR), mechanical ventilation (MV), and admission to the acute care ward (ACW) in the last 7 days of life. RESULTS: Among 224,391 patients, the proportion of patients receiving LST varied by region. CPR ranged from 8.6% (Chubu) to 12.9% (Shikoku), MV ranged from 7.1% (Chubu) to 12.3% (Shikoku), and admission to ACW ranged from 4.5% (Chubu) to 10.1% (Kyushu-Okinawa). The adjusted odds ratios (AOR) for regional variation compared with Kanto were as follows: CPR (in Shikoku, 1.85 [95% CI 1.73 - 1.98]), MV (in Shikoku, 1.75 [1.63 - 1.87]), and ACW admission (in Kyushu-Okinawa, 1.69 [1.52 - 1.88]). CONCLUSION: The study presents descriptive information regarding regional differences in the utilization of LST for the oldest old. Further research is necessary to identify the factors that contribute to these variations and to address the challenge of improving the quality of end-of-life care.

A palliative care goals model for people with dementia and their family: Consensus achieved in an international Delphi study.

BACKGROUND: Advance care planning in dementia includes supporting the person and their family to consider important goals of care. International research reports the importance of psycho-social-spiritual aspects towards end of life. AIM: To develop a multidimensional international palliative care goals model in dementia for use in practice. DESIGN: International Delphi study integrating consensus and evidence from a meta-qualitative study. The Delphi panel rated statements about the model on a 5-point agreement scale. The criteria for consensus were pre-specified. SETTING/PARTICIPANTS: Seventeen researchers from eight countries developed an initial model, and 169 candidate panellists were invited to the international online Delphi study. RESULTS: Panellists (107; response 63.3%) resided in 33 countries. The model comprised four main care goals: (1) Comfort ensured; (2) Control over function maintained; (3) Identity protected and personhood respected and (4) Coping with grief and loss-person and caregiver supported. The model reflects how needs and care goals change over time with the progression of dementia, concluding with bereavement support. The first version of the model achieved a consensus after which it was slightly refined based on feedback. We did not achieve a consensus on adding a goal of life prolongation, and on use of the model by people with dementia and family themselves. CONCLUSION: A new palliative care goals model for people with dementia and their families includes relationship aspects for use by professionals and achieved a consensus among a panel with diverse cultural background. The position of life prolongation in relation to palliative care goals needs further research.

Teenage and young adult pregnancy and depression: findings from the Japan environment and children's study.

Teenage pregnancy increases the threat of depression because of its many factors. Pregnancy during young adulthood may also have several risk factors for depression compared to older pregnancies. However, data on depression in young adult pregnancies are lacking. This study investigated the association between teenage and young adult pregnancy and depression. Data from the Japan Environment and Children's study was used as a nationwide multicenter prospective cohort study. A multivariate logistic regression was performed to investigate the association between age groups (14-19, 20-24, 25-29, 30-34, ≥ 35 years) and depression, adjusted for behavioral and sociodemographic characteristics. Depression was assessed using the Kessler Psychological Distress Scale. In total, 96,808 pregnant women responded to the questionnaire. Teenage (14-19 years) and young adult (20-24 years) pregnancy were associated with an increased risk of depression compared to older pregnancy (≥ 35 years) (teenage: OR 4.28, 95% confidence interval, CI [3.24-5.64]; young adult: OR 3.00, 95% CI [2.64-3.41]). After adjusting for covariates, the magnitude of the risk of depression was attenuated. However, teenage and young adult pregnancy remained at a significantly increased risk of depression compared to older pregnancy (teenage: OR 2.38, 95% CI [1.77-3.21]; young adult: OR 2.14, 95% CI [1.87-2.46]). Our findings indicate that teenage and young adults' pregnancy are at an increased risk of depression compared to older pregnancy. These findings suggest prioritizing teenage and young pregnant women for prevention and interventions related to depression.

Effectiveness of e-learning material on essential components of evidence-based medicine among laypersons: a randomized controlled trial.

Evidence-based medicine (EBM) is helpful for laypersons' decision-making. This study aimed to evaluate the effectiveness of e-learning materials on the essential components of EBM for laypersons. We conducted a web-based, open-label, randomized controlled trial with laypersons in Japan aged ≥20 years who used the internet. Participants were randomly assigned to the intervention group with the e-learning material and the control group with only the 'Introduction' section of the same material. The primary and secondary outcomes were the self-created acquirement test scores (responding correctly with confidence) immediately after using the material and after 4 weeks. A multiple linear regression analysis was conducted. Of the 122 participants, 62 were randomly assigned to the intervention group and 59 to the control group; finally, 59 and 58, respectively, were included in the full analysis set. The mean (standard deviation) of the acquirement test score immediately after learning was 14.11 and (3.11) and 11.07 (3.88) in the intervention and control groups, respectively, indicating statistical significance (multivariable P < 0.001). The secondary long-term outcome was also statistically significant. The results showed that the e-learning material was effective for laypersons in acquiring the essential components of EBM. The material may increase laypersons' confidence in appraising health information, which can be used in decision-making.

Declining trend in the estimated annual rupture rate of unruptured cerebral aneurysms in Japan: a nationwide study.

The incidence of subarachnoid hemorrhages (SAHs) in Japan has recently decreased. However, trends in the annual rates of unruptured cerebral aneurysms (UCAs) are unclear because calculations based on follow-up periods are limited to patients with ruptured cerebral aneurysms. We aimed to clarify current trends in the estimated annual rupture rates of UCAs in Japan and to identify the most relevant contributing factors. We analyzed data from the Japanese Ministry of Health, Labour and Welfare and records of the Japan Neurosurgical Society. The estimated annual rupture rates of UCAs between 2003 and 2018 were calculated according to age-adjusted mortality rates of SAH and number of treated ruptured cerebral aneurysms (RCAs). We estimated trends in annual rupture rates using sensitivity analysis and assessed associations between estimated annual rupture rates and the prevalences of hypertension and current smoking. The estimated annual rupture rate of UCAs significantly decreased from 1.44 to 0.87% and from 0.92 to 0.76%, respectively, in terms of age-adjusted mortality rates of SAH and number of treated RCAs (p < 0.001). The range of changes in estimated annual rupture rates of UCAs was - 1.13%‒0.83%, representing a declining UCA trend of 88%. The estimated annual rupture rates of UCAs declined by 0.02-0.10% and 0.01-0.05% with every percent decrease in hypertension and current smoking prevalence, respectively. The estimated annual rupture rate of UCAs has recently decreased in Japan, possibly due to a decrease in the prevalence of hypertension rather than smoking.

Children's injuries in legislated types child-care institutions.

BACKGROUND: Severe injuries in child-care institutions are an important social issue. However, no reports on this matter have been made in Japan. This study examined trends in severe injuries at child-care institutions, including the impact of the coronavirus disease 2019 (COVID-19) pandemic. METHODS: We conducted a serial cross-sectional study and interrupted time-series (ITS) analysis with a linear regression model to assess trends in the incidence rate of severe injuries using Japanese national open data between January or April 2017 and December 2021. Participants were individuals utilizing legislated types child-care institutions. The outcomes were annual and monthly incidence rates of severe injuries in legislated types child-care institutions. RESULTS: The number of legislated types child-care institutions increased from 32,793 facilities in 2017 to 38,666 facilities in 2021, and the number of participants rose from 2,802,228 in 2017 to 3,059,734 in 2021. The annual incidence rate of severe injuries in 2021 was 58.3 cases per 100,000 person-years, which is twofold higher than that in 2017. The ITS for the monthly incidence rate demonstrated an increasing trend before the COVID-19 pandemic. CONCLUSIONS: Before the COVID-19 pandemic, the monthly incidence rate of severe injuries in legislated types child-care institutions increased. The annual incidence rate in Japan may have also increased during the observation period.

eHealth Literacy and Web-Based Health Information-Seeking Behaviors on COVID-19 in Japan: Internet-Based Mixed Methods Study.

BACKGROUND: During the COVID-19 pandemic, much misinformation and disinformation emerged and spread rapidly via the internet, posing a severe public health challenge. While the need for eHealth literacy (eHL) has been emphasized, few studies have compared the difficulties involved in seeking and using COVID-19 information between adult internet users with low or high eHL. OBJECTIVE: This study examines the association between eHL and web-based health information-seeking behaviors among adult Japanese internet users. Moreover, this study qualitatively shed light on the difficulties encountered in seeking and using this information and examined its relationship with eHL. METHODS: This cross-sectional internet-based survey (October 2021) collected data from 6000 adult internet users who were equally divided into sample groups by gender, age, and income. We used the Japanese version of the eHL Scale (eHEALS). We also used a Digital Health Literacy Instrument (DHLI) adapted to the COVID-19 pandemic to assess eHL after we translated it to Japanese. Web-based health information-seeking behaviors were assessed by using a 10-item list of web sources and evaluating 10 topics participants searched for regarding COVID-19. Sociodemographic and other factors (eg, health-related behavior) were selected as covariates. Furthermore, we qualitatively explored the difficulties in information seeking and using. The descriptive contents of the responses regarding difficulties in seeking and using COVID-19 information were analyzed using an inductive qualitative content analysis approach. RESULTS: Participants with high eHEALS and DHLI scores on information searching, adding self-generated information, evaluating reliability, determining relevance, and operational skills were more likely to use all web sources of information about COVID-19 than those with low scores. However, there were negative associations between navigation skills and privacy protection scores when using several information sources, such as YouTube (Google LLC), to search for COVID-19 information. While half of the participants reported no difficulty seeking and using COVID-19 information, participants who reported any difficulties, including information discernment, incomprehensible information, information overload, and disinformation, had lower DHLI score. Participants expressed significant concerns regarding "information quality and credibility," "abundance and shortage of relevant information," "public trust and skepticism," and "credibility of COVID-19-related information." Additionally, they disclosed more specific concerns, including "privacy and security concerns," "information retrieval challenges," "anxieties and panic," and "movement restriction." CONCLUSIONS: Although Japanese internet users with higher eHEALS and total DHLI scores were more actively using various web sources for COVID-19 information, those with high navigation skills and privacy protection used web-based information about COVID-19 cautiously compared with those with lower proficiency. The study also highlighted an increased need for information discernment when using social networking sites in the "Health 2.0" era. The identified categories and themes from the qualitative content analysis, such as "information quality and credibility," suggest a framework for addressing the myriad challenges anticipated in future infodemics.

Exploratory Online Survey Regarding Perceptions of Health Inequities Influenced by Social Determinants of Health Among Cardiovascular Disease Patients.

Despite establishing conventional risk factors and preventive medicine for cardiovascular diseases (CVD), there remains a notable lack of research for identifying social determinants of health (SDOH). The aim of this study was to identify the SDOH domains contributing to health inequities perceived by Japanese CVD citizens. An online survey was conducted among 2,083 Japanese CVD patients from November 7 to 13, 2023, to assess their perceptions of 19 social determinants of health (SDOH) domains and their impact on health inequities. Using the 5-point Likert scale, a high level of agreement was defined as over 50% selecting "Agree" or "Strongly Agree." The "Health inequity perception score (HIPS)" was calculated by assigning 1 point for 'Agree' and 2 points for 'Strongly Agree.' Additionally, patient factors that defined a group with HIPS above the median were also evaluated. High agreement was noted in 7 out of 19 domains: "Employment" (61%), "Food Insecurity" and "Environmental Condition" (each at 60%), "Poverty" (58%), "Early Childhood Development and Education" (57%), "Housing Instability and Quality" (56%), and "Access to Health Service" (52%). Young age, high annual income, high educational level, and living alone were significantly associated with high HIPS. This study highlights that several SDOH factors commonly acknowledged in Western contexts are also recognized as contributors to health inequities among Japanese CVD patients.

[Utilization of the standard questionnaire in specific health checkups].

Objectives　Interviewing people about their health behaviour in specific health checkups (SHCs) is thought to promote awareness of and help improve such behaviour. The standard questionnaire (SQ) for SHCs consists of 22 items presented in the guidelines of the Ministry of Health, Labour, and Welfare. However, using items other than those necessary for stratification for specific health guidance (SHG) is optional. We believe that clarifying the actual utilization of SQ items could contribute to improving the procedure used for the fourth SHCs and SHG, which will be initiated in 2024.　This study seeks to clarify the actual utilization of the SQ for (1) conducting SHCs, (2) planning, implementing, and evaluating SHG and health programs aimed at preventing lifestyle-related diseases, and (3) planning, implementing, and evaluating the data health plan.Methods　We enrolled 3,179 people from 1,741 departments in charge of national health insurance, 47 Japan Health Insurance Association branches, and 1,391 health insurance societies across all municipalities in Japan. One participant among the study participants was the main person in charge of SHCs and SHG at each facility. We conducted a self-reported survey on the implementation of SHCs and SHG in February 2022. This study was approved by the ethics review board of the institution to which the first author belongs.Results　A total of 1,221 (38.4%) were received. The proportions of valid responses from national health insurance departments, Japan Health Insurance Association branches, and health insurance societies were 816 (46.9%), 47 (100%), and 358 (25.7%), respectively. Over 96% of responders used the group SHCs method, and over 93% of those adopting the individual SHCs method used each of the 22 SQ items. However, 187 (18.2%) responders found it difficult to use the item "If you had the opportunity to receive health guidance for lifestyle improvement, would you take it?" The reason was that the on-request SHG system was misunderstood. Additionally, only approximately 50% of respondents used the SQ to develop, implement, and evaluate their health program.Conclusion　We believe there will be no problem in implementing the SQ even if using all its component items is required. However, the aforementioned item needs to be revised. Methods to encourage health insurers and their supporters to use the SQ for health-related data collection and health program planning should be devised.

[Evidence-based medicine and clinical ethics: toward shared decision making].

Evidence-based medicine (EBM) is "decision-making for better patient care that integrates current evidence, and clinical expertise with patients' preferences, values and circumstances." It is important to distinguish research evidence from EBM, which is comprehensive decision-making that takes into account the diversity and individuality of clinical situations while respecting evidence as a general theory. Clinical practice guidelines are "a document that evaluates the total body of evidence through systematic review and presents recommendations that are considered optimal, taking into account the balance of benefits and harms, in order to support decision-making on important health-related issues by healthcare users and providers," and is useful in the practice of EBM. Shared decision making (SDM), which has been attracting attention in recent years, is "a process in which the patient and the health care provider, through dialogue, decide on a treatment plan that is acceptable to the patient, based on the patient's own preferences and values, research evidence, and clinical expertise" and must be understood in relation to the above definition of EBM and from the perspective of clinical ethics.

Relationship between hospital surgical volume and the perioperative esophagectomy costs for esophageal cancer: a nationwide administrative claims database study.

BACKGROUND: Numerous studies have described positive relationships between hospital volume (HV) and clinical outcomes in highly complex procedures, including esophagectomies. Although the centralization of surgery has been considered a possible solution for improving clinical outcomes, the HV impact on perioperative healthcare costs is unknown. This study aimed to determine the relationship between HV and perioperative healthcare costs for patients undergoing esophagectomy for esophageal cancer. METHODS: This retrospective, nationwide cohort study used Japanese Administrative Claims Database data. Data on esophagectomies performed nationwide in 2015 were extracted. The outcome measure was perioperative healthcare costs per person from the perspective of the insurer. The healthcare costs in outpatient or inpatient settings of any hospital and clinic where patients received treatment were summed up from the month the surgery was performed to 3 months after. Linear regression analyses were conducted to assess the risk-adjusted effects of the HV category (1-4/5-9/10-14/15-) on perioperative costs. RESULTS: A total of 5232 patients underwent an esophagectomy at 584 hospitals. The overall perioperative cost was 20.834 billion Japanese yen (JPY). The median perioperative costs per person for each HV category (1-4/5-9/10-14/15-) were 3.728 (709 patients), 3.740 (658 patients), 3.760 (512 patients), and 3.760 (3253 patients) million JPY, respectively (P = 0.676). Multivariate analyses revealed that each HV category had no significant impact on perioperative costs. CONCLUSIONS: There were no significant differences in the perioperative costs between high- and low-volume centers. Esophageal cancer surgery centralization may be achievable without increasing healthcare costs.

Trends and future projections of cervical cancer-related outcomes in Japan: What happens if the HPV vaccine program is not implemented?

Contrary to other developed countries, in Japan, recent years have seen increases in cervical cancer incidence and mortality among young people. However, the human papillomavirus (HPV) vaccine program, a key measure for avoiding cervical cancer, has been virtually suspended. Temporal changes in cervical cancer profiles in this unique situation have not been fully investigated epidemiologically. Our study aimed to determine the current status and future trends of the incidence and mortality of cervical cancer and precancerous lesions in Japan. Mortality rates of cervical cancer during 1975 to 2016 and incidence rates of cervical cancer and cervical intraepithelial neoplasia (CIN) 3 during 1975 to 2013 were examined using vital statistics and population-based cancer registry data in Japan. Bayesian age-period-cohort analyses were performed to analyze temporal changes of the three cervical cancer-related outcomes. We also calculated projections to 2028 for the three outcomes, assuming that HPV vaccination coverage and screening rates in Japan would be maintained at the current level after the resumption of the national vaccination program. The risk of occurrence of the three outcomes showed similar changes by birth cohort, peaking in the mid-1890s to 1900s birth cohorts, declining sharply in the 1940s birth cohort, and persistently increasing in the 1950s and later birth cohorts. Projections to 2028 show increases in cervical cancer incidence and mortality in the 30 to 69 age group, with a particular increase in CIN3 incidence in the 25 to 49 age group, if HPV vaccine programs and screening are not effectively implemented. These findings revealed an increasing cervical disease burden among reproductive age females in Japan.

Comparison of Minimally Invasive Surgery with Open Surgery for Remnant Gastric Cancer: A Multi-institutional Cohort Study.

BACKGROUND: Despite growing evidence of the effectiveness of minimally invasive surgery (MIS) for primary gastric cancer, MIS for remnant gastric cancer (RGC) remains controversial due to the rarity of the disease. This study aimed to evaluate the surgical and oncological outcomes of MIS for radical resection of RGC. PATIENTS AND METHODS: Patients with RGC who underwent surgery between 2005 and 2020 at 17 institutions were included, and a propensity score matching analysis was performed to compare the short- and long-term outcomes of MIS with open surgery. RESULTS: A total of 327 patients were included in this study and 186 patients were analyzed after matching. The risk ratios for overall and severe complications were 0.76 [95% confidence interval (CI): 0.45, 1.27] and 0.65 (95% CI: 0.32, 1.29), respectively. The MIS group had significantly less blood loss [mean difference (MD), -409 mL; 95% CI: -538, -281] and a shorter hospital stay (MD, -6.5 days; 95% CI: -13.1, 0.1) than the open surgery group. The median follow-up duration of this cohort was 4.6 years, and the 3-year overall survival were 77.9% and 76.2% in the MIS and open surgery groups, respectively [hazard ratio (HR), 0.78; 95% CI: 0.45, 1.36]. The 3-year relapse-free survival were 71.9% and 62.2% in the MIS and open surgery groups, respectively (HR, 0.71; 95% CI: 0.44, 1.16). CONCLUSIONS: MIS for RGC showed favorable short- and long-term outcomes compared to open surgery. MIS is a promising option for radical surgery for RGC.

Sleep disordered breathing and haemoglobin A1c levels within or over normal range and ageing or sex differences: the Nagahama study.

Recently an association between blood glucose dysregulation and sleep disruption was suggested. The association between sleep disordered breathing, most of which is due to obstructive sleep apnea (OSA) in the general population, and diabetic severity, as well as the impact of antidiabetic treatment, remains unclear. This study aimed to investigate these associations as well as age and sex differences. This cross-sectional study evaluated 7,680 community participants as the main cohort (population-based cohort). OSA was assessed by the 3% oxygen desaturation index from pulse oximetry, which was corrected for sleep duration obtained by wrist actigraphy. For arguing the limitations for using pulse oximetry, 597 hospitalised patients, who were assessed by the apnea-hypopnea index from attended polysomnography, were also evaluated as the validation cohort (hospital-based cohort). Moderate-to-severe OSA was more prevalent as haemoglobin A1c (HbA1c) levels increased (<5.6%/5.6%-<6.5%/6.5%-<7.5%/≥7.5%, respectively) in both cohorts (p < 0.001), but only in those without antidiabetic treatment. The HbA1c level was an independent factor for moderate-to-severe OSA (population-based cohort, odds ratio [OR] 1.26, 95% confidence interval [CI] 1.10-1.45; hospital-based cohort, OR 1.69, 95% CI 1.22-2.33, per 1% increase). These associations were more prominent in the middle-aged (aged <60 years) than in the elderly (aged ≥60 years) and in women than in men in both cohorts. The prevalence of moderate-to-severe OSA in patients with antidiabetic treatment in the hospital-based cohort was ≥75% regardless of HbA1c levels. In conclusion, an association between the prevalence of OSA and HbA1c level even within or over the normal range was found only in patients without antidiabetic treatment and was more prominent in the middle-aged and in women.

Impact of fibrosis on liver-related event incidence in nonalcoholic fatty liver disease: A multicenter observational study.

AIM: There are few reports on the prognosis of liver-related events in Japanese patients with nonalcoholic fatty liver disease (NAFLD). We undertook an observational study to compare the prognosis between fibrotic and nonfibrotic groups in Japanese NAFLD patients. METHODS: Prognosis in 393 NAFLD patients who underwent liver biopsy between April 2013 and April 2015 at multiple centers were investigated. The time to onset of liver-related events, cardiovascular events, development of extrahepatic cancers, and death were compared between the pathologically fibrotic nonalcoholic steatohepatitis (NASH) group and nonalcoholic fatty liver (NAFL) + nonfibrotic NASH group. A similar analysis was carried out based on the fibrotic classification diagnosed using four noninvasive fibrosis prediction models. RESULTS: The mean age and body mass index at the time of liver biopsy was 55.7 years old and 28.04 kg/m2 , respectively The cumulative incidence of liver-related events at 1080 days after liver biopsy was 5.79% in the pathologically fibrotic NASH group and 0% in the NAFL + nonfibrotic NASH group, with a significant difference (p = 0.0334). The cumulative incidence of liver-related events was significantly higher in the positive group for the prediction model than in the negative group in all four models (all p values were <0.0001). There was no significant difference between the pathologically fibrotic NASH group and NAFL + nonfibrotic NASH group in terms of cumulative incidence of cardiovascular events, development of extrahepatic cancers, and death. CONCLUSIONS: The incidence of liver-related events was significantly higher in the fibrotic NASH group than that of the NAFL + nonfibrotic NASH group in Japanese NAFLD patients.

Systematic review and meta-analysis of the efficacy of benzodiazepines for dyspnea in patients with cancer.

OBJECTIVE: the role of benzodiazepines in relieving dyspnea in patients with cancer has not yet been established. This systematic review and meta-analysis aimed to determine the efficacy and safety of benzodiazepines alone or in combination with opioids for dyspnea in patients with cancer. METHODS: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and Ichushi-Web were searched for articles published from database inception to 23 September 2019. Studies of benzodiazepines alone or in combination with opioids for dyspnea were included. The primary outcome measure was the relief of dyspnea. The secondary outcome measures were anxiety, somnolence and severe adverse events. RESULTS: of 505 publications initially identified, two trials and one trial were included in the meta-analysis of midazolam alone and in combination with morphine, respectively. With regard to the relief of dyspnea, midazolam alone showed no significant difference compared with morphine alone, with a relative risk of 0.95 (95% confidence interval: 0.47-1.89). Meanwhile, midazolam plus morphine was significantly more effective than morphine alone, with a relative risk of 1.33 (95% confidence interval: 1.02-1.75). For anxiety relief, a meta-analysis could not be performed because of insufficient data. The incidence of somnolence and severe adverse events was not significantly different between the experimental and control groups for either midazolam alone or in combination with morphine. CONCLUSIONS: benzodiazepines alone do not significantly improve dyspnea compared with opioids alone, but a combination of benzodiazepines and opioids may be more effective. Evidence from randomized controlled trials focusing on patients with cancer has not been generated in recent years. Further appropriately designed randomized controlled trials are required.
