Mortality and neurodevelopmental outcomes in very low birth weight infants with esophageal atresia.

PURPOSE: Very low birth weight infants (VLBWIs) have been thought as risk of bad outcomes in the patients with esophageal atresia (EA). However, detailed outcomes of EA within VLBWIs were not fully understood. We aimed to reveal short- and long-term outcomes in VLBWIs with EA. METHODS: Clinical data regarding VLBWIs with EA registered in Neonatal Research Network Japan, a multicenter research database in Japan, were collected. Patients with chromosomal abnormality were excluded. Short term outcome was survival discharge from NICU and long-term outcome was neurodevelopmental impairment (NDI) at 3 years. RESULTS: A total of 103 patients were analyzed. the overall survival discharge rate from NICU was 68.0% (70/103). The risk of death was increased as the birth weight got reduced. The presence of associated anomaly increased the risk of death. Three-year neurodevelopmental information was available in 32.9% (23/70) of patients. Of the 23 included patients for 3-year follow-up, 34.8% had NDI. The risk of NDI was increased as the birth weight reduced. CONCLUSIONS: In VLBWIs with EA, survival discharge from NICU was still not high. More immature patients and patients with an associated anomaly had worse outcomes. Among patients who survived, NDI was confirmed in a certain number of patients.

Hydrochlorothiazide increases risk of nonmelanoma skin cancer in an elderly Japanese cohort with hypertension: The Shizuoka study.

Background: Hydrochlorothiazide (HCT), a widely used hypertensive drug, has photocarcinogenic potential, leading to concerns about the development of nonmelanoma skin cancers (SCs) after intake. Despite substantial numbers of observational studies, the results remain inconsistent especially among Asian countries. Objective: To assess the incidence of nonmelanoma SCs in hypertensive Japanese HCT users compared with nonusers. Methods: A population-based, cohort nested, propensity score-matched study was conducted using the Shizuoka Kokuho database. All participants were patients aged ≥60 years. Hazard ratios for SC incidence were calculated in the matched cohorts using the propensity scores of potential confounders, sex, age category, comorbidities, and administration of methotrexate, cyclosporin, and statins. Results: The risk of SC was higher in HCT users than in nonusers (hazard ratio, 1.58; 95% confidence interval, 1.04-2.40), with preferential sun-exposed location and a tendency to develop squamous cell carcinoma, but not basal cell carcinoma or Bowen disease. Limitations: No additional information was available from other than medical records. The data were confined to a Japanese population. Conclusion: HCT use increases the risk of SC in Japanese patients with hypertension and a dark skin type, highlighting the increased risk of SC among HCT users in the aging society worldwide.

Administration of Tranexamic Acid After Burr Hole Craniotomy Reduced Postoperative Recurrence of Chronic Subdural Hematoma in a Japanese Regional Population.

BACKGROUND: Although tranexamic acid (TXA) has occasionally been used to prevent postoperative recurrence of chronic subdural hematoma (CSDH) after burr hole craniotomy (BC), robust evidence of its efficacy has been lacking. OBJECTIVE: To assess the efficacy and safety of postoperative oral administration of TXA after BC for CSDH among the elderly. METHODS: This retrospective, propensity score-matched cohort study was carried out with a large Japanese local population-based longitudinal cohort in the Shizuoka Kokuho Database between April 2012 and September 2020. Patients included were age 60 years or older and had undergone BC for CSDH but were not undergoing dialysis. Covariates were collected from records of the preceding 12 months from the month of first BC, and patients were followed up for 6 months after surgery. The primary outcome was repeat surgery, and the secondary outcome was death or the onset of thrombosis. Data on postoperative TXA administration were collected and compared with controls using propensity score matching. RESULTS: Of the 8544 patients who underwent BC for CSDH, 6647 were included, with 473 placed in the TXA group and 6174 placed in the control group. After 1:1 matching, repeated BC was found to have been performed in 30 of 465 patients (6.5%) in the TXA group and in 78 of 465 patients (16.8%) in the control group (relative risk, 0.38; 95% CI, 0.26-0.56). No significant difference was observed for death or the onset of thrombosis. CONCLUSION: Oral administration of TXA reduced the occurrence of repeat surgery after BC for CSDH.

Association of Hemoglobin and Hematocrit Levels during Pregnancy and Maternal Dietary Iron Intake with Allergic Diseases in Children: The Japan Environment and Children's Study (JECS).

Few epidemiologic studies have examined the role of maternal iron status in allergic diseases in offspring and findings have been inconsistent. We used a large birth cohort in Japan to explore the association of the markers for maternal iron status (maternal hemoglobin, hematocrit and dietary iron intake during pregnancy) with allergy development in offspring during early childhood. We analyzed information on children age 0-3 years from the Japan Environment and Children's Study (JECS). We used logistic models and generalized estimating equation models to evaluate the effect of maternal hemoglobin and hematocrit levels and dietary iron intake on allergies in children. Models were also fitted with propensity score-matched datasets. Data were collected for a total of 91,247 mother-child pairs. The prevalence (95% confidence interval) of low hemoglobin and hematocrit was 14.0% (13.7-14.2%) and 12.5% (12.3-12.8%), respectively. After adjusting confounders, low hemoglobin and hematocrit during pregnancy were not associated with childhood allergic outcomes. Findings from models with propensity score-matched datasets also indicated that children born to mothers with low hemoglobin or hematocrit levels during pregnancy did not have a higher risk of developing allergic conditions at 3 years old. We found no meaningful associations between low energy adjusted maternal dietary iron intake and allergies in children. In conclusion, using birth cohort data, we found no evidence supporting an association of low maternal hemoglobin, hematocrit and low dietary iron intake with allergy symptoms during early childhood. Further studies with more suitable proxy markers for blood iron status are needed.

A scoping review of palliative care for children in low- and middle-income countries.

BACKGROUND: Ninety-eight percent of children needing palliative care live in low- and middle-income countries (LMICs), and almost half of them live in Africa. In contrast to the abundance of data on populations in high income countries, the current data on populations in LMICs is woefully inadequate. This study aims to identify and summarize the published literature on the need, accessibility, quality, and models for palliative care for children in LMICs. METHODS: A scoping review was performed following the method of Arksey and O'Malley. Systematic searches were conducted on PubMed and Google Scholar using the main keywords, 'children AND palliative care OR terminal care OR hospice OR end of life AND developing countries OR LMICs.' Additional publications were obtained by handsearching. Papers were only included if they reported on the need, accessibility, quality, and models for palliative care for children in LMICs. RESULTS: Fifteen papers met the inclusion criteria for review. Of these, 10 assessed need, seven examined availability and/or accessibility, one assessed quality, and one examined the models. We found an urgent need for palliative care, particularly in the training for health workers and improving poor availability and/or accessibility to palliative care in terms of factors such as medication and bereavement support. The best practice models demonstrated feasibility and sustainability through cooperation with governments and community organizations. The quality of pain management and emotional support was lower in LMICs compared to HICs. CONCLUSION: Although we found limited evidence in this review, we identified common challenges such as the need for further training for health workers and greater availability of opioid analgesics. While efforts to change the current systems and laws applying to children in LMICs are important, we should also tackle underlying factors including the need to raise awareness about palliative care in public health and improve the accuracy of data collection.

Re-invigorating Japan's commitment to global health: challenges and opportunities.

Over the past 50 years, Japan has successfully developed and maintained an increasingly equitable system of universal health coverage in addition to achieving the world's highest life expectancy and one of the lowest infant mortality rates. Against this backdrop, Japan is potentially in a position to become a leading advocate for and supporter of global health. Nevertheless, Japan's engagement with global health has not been outstanding relative to its substantial potential, in part because of government fragmentation, a weak civil society, and lack of transparency and assessment. Japan's development assistance for health, from both governmental and non-governmental sectors, has remained low and Japanese global health leadership has been weak. New challenges arising from changes in governance and global and domestic health needs, including the recent Great East Japan Earthquake, now provide Japan with an opportunity to review past approaches to health policy and develop a new strategy for addressing global and national health. The fragmented functioning of the government with regards to global health policy needs to be reconfigured and should be accompanied by further financial commitment to global health priorities, innovative non-governmental sector initiatives, increased research capacity, and investments in good leadership development as witnessed at the G8 Hokkaido Toyako Summit. Should this strategy development and commitment be achieved, Japan has the potential to make substantial contributions to the health of the world as many countries move toward universal coverage and as Japan itself faces the challenge of maintaining its own health system.
