ABSTRACT
BACKGROUND: Spontaneous hemopneumothorax is a rare condition that can be life-threatening if not promptly diagnosed and treated. We report a case of early treatment with transcatheter arterial embolization and video-assisted thoracoscopic surgery. CASE PRESENTATION: A 19-year-old Japanese male was diagnosed with left pneumothorax and underwent chest tube drainage. A total of 10 hours after admission, the patient developed dyspnea, chest pain, and sudden massive bloody effusion. Contrast-enhanced computed tomography revealed contrast extravasation near the left lung apex, and spontaneous hemopneumothorax was diagnosed. Angiography revealed bleeding from a branch of the subscapular artery and transcatheter arterial embolization was performed. The patient underwent video-assisted thoracoscopic surgery and recovered uneventfully. CONCLUSIONS: Anesthesiologists involved in urgent surgeries must be aware that a patient with spontaneous pneumothorax can develop a hemopneumothorax, even when full lung expansion has been obtained following chest tube drainage, owing to latent aberrant artery disruption. Interprofessional team engagement is essential for spontaneous hemopneumothorax management.

OBJECTIVE: To describe characteristics of published research on the safety and efficacy of vitamin K antagonists (VKA) for pregnant patients with antiphospholipid antibodies (aPLs), including their methodological characteristics and knowledge gaps. METHODS: This study followed the Joanna Briggs Institute Methodology for Scoping Reviews (JBI) methodology and utilized the PRISMA-ScR protocol system. Studies were primarily identified through searching electronic databases including MEDLINE, EMBASE, Web of Science and the Cochrane Central Register of Controlled Trials. Study characteristics and outcomes were reported and described using customized charting tables. RESULTS: Of 1,528 publications, 17 remained in the final analysis. These reported up to 190VKA-treated aPL-positive pregnancies diagnosed as antiphospholipid syndrome (APS), where pregnancies were likely overlapping cases in some publications. In the 17 reports, there were 723 individuals in comparison groups, including healthy, pre-treatment pregnancies or APS women treated with standard therapies without VKA. However, only 4 (23.5%) of the 17 publications stated a study objective focusing on VKA use, of which only one was a full-length article. In addition, information on VKA doses, disease diagnostic criteria and the long-term outcome of the offspring were largely absent. CONCLUSION: The current evidence is insufficient to assess VKA efficacy and safety profiles in aPL-positive pregnant patients. Studies with a defined focus on VKA use in this population are lacking, and reporting of key information is not consistent. The relative lack of the knowledge of VKA use in pregnant women with APS is concerning, and the efficacy and safety questions remain open.
ABSTRACT
BACKGROUND: Patients with heart failure (HF) experience a wide variety of symptoms. Appropriate recognition of symptoms is important in HF care. The Heart Failure Somatic Perception Scale (HFSPS) measures the presence of HF symptoms and the degree to which physical symptoms are bothersome. OBJECTIVE: The aim of this study was to assess the validity and reliability of the Japanese version of the HFSPS. METHODS: Confirmatory factor analysis was used to assess structural validity. Construct validity was assessed using Spearman's rank correlation coefficient to evaluate the association between HFSPS total and subscale scores and global physical health on the Patient-Reported Outcomes Measurement Information System. Internal consistency was assessed using the model-based internal consistency for the HFSPS as a whole and Cronbach α for the subscales. RESULTS: Participants were 315 Japanese outpatients (72.1% male), with a mean age of 72.9 ± 12.9 years. The result of confirmatory factor analysis was an adequate model fit by adding error correlations. Construct validity was significant for the correlation with global physical health of the Patient-Reported Outcomes Measurement Information System. The model-based internal consistency was 0.95. Cronbach αs for each subscale were 0.88 for dyspnea, 0.60 for chest discomfort, 0.77 for early and subtle symptoms, and 0.77 for edema. CONCLUSIONS: The findings support the use of the HFSPS in a more diverse population, suggesting that it is a reliable and valid instrument in Japanese patients with HF. The HFSPS may provide an accurate assessment of the symptoms experienced by patients with HF in daily life in future educational intervention studies to improve symptom perception and coping behaviors.
ABSTRACT
INTRODUCTION/OBJECTIVE: In Asia, 42% of young children suffer from iron deficiency anemia. Children have an increased requirement for iron intake because of growth and physical activity. Education plays an important role in anemia prevention and in ensuring children are aware of appropriate iron intake and the iron content of different foods. As a tool for this purpose, we adapted the adult version of the Revised Iron Intake Scale (RIIS) to create the Child and Adolescent Version of the Iron Intake Scale (CIIS), using illustrations to help children recognize the foods listed in the CIIS. We aimed to evaluate the validity and reliability of this new scale. METHODS: We conducted a cross-sectional study using a self-administered questionnaire to examine the criterion-related validity of the CIIS. We used Spearman's rank correlation coefficient to compare iron intake estimated by the CIIS with that calculated by the Brief-type Diet History Questionnaire (BDHQ-15y), which assesses respondents' dietary habits over the past month and is standardized among Japanese children. The survey was repeated twice to examine reliability. RESULTS: We found a moderate positive correlation for iron intake between the CIIS and BDHQ-15y, with a correlation coefficient of .52 (n = 258, P < .001). Cronbach's alpha coefficient was .718. The CIIS reproducibility test yielded a correlation coefficient of .67. CONCLUSION: Our results indicated that the CIIS was valid, reliable, and reproducible. We therefore believe that the scale can be used to improve education about iron deficiency anemia and thereby reduce anemia rates among children and adolescents.

BACKGROUND AND OBJECTIVES: To examine the reliability and validity of the Japanese version of the Dutch Eating Behavior Questionnaire (DEBQ-J) for patients with mental illness, and to determine the characteristics of eating behavior among these patients when compared with healthy controls. METHODS AND STUDY DESIGN: In May 2018, 120 outpatients with mental illness and 132 healthy controls were surveyed. First, exploratory factor analysis was conducted on the DEBQ-J statement responses for both patients and healthy controls. Next, reliability coefficients were calculated for the eating behavior scale scores (emotional, restrained, and external eating) extracted from the factor analysis. The association between BMI and eating behavior was examined using Student's t-test and Pearson's correlation coefficient. RESULTS: The DEBQ-J had a similar factor structure to that of the original DEBQ for healthy controls, with a cumulative contribution of 52.4% for the three factors, and alpha coefficients ranging from 0.87 to 0.91. For patients, factor analysis showed that four statements classified as emotional eating items in the original DEBQ were recategorized as external eating items, and the percentage of patients with obesity (BMI≥25) was 57.5%, compared with only 25.4% among the healthy controls. The patients with obesity tended to score higher on the external eating scale than did those with BMI<25. CONCLUSIONS: Patients tended to blur the distinction between emotional feelings of mental irritability or anxiety and feelings in response to external stimuli. Monitoring of the DEBQ-J external eating score and appropriate intervention among patients living with mental illness may help to prevent obesity.

BACKGROUND: Lactating mothers taking ezetimibe, an antihyperlipidemic agent, may be hesitant to breastfeed despite the known benefit of breastfeeding to both mother and infant. Currently, no data exist on the presence or concentration of ezetimibe and its main active metabolite, ezetimibe-glucuronide (EZE-glucuronide), in human breast milk. METHODS: Voluntary breast milk samples containing ezetimibe and EZE-glucuronide were attained from lactating mothers taking ezetimibe as part of their treatment. An assay was developed and validated to measure ezetimibe and EZE-glucuronide concentrations in breast milk. A workflow that utilized a developed and evaluated pediatric physiologically based pharmacokinetic (PBPK) model, the measured concentrations in milk, and weight-normalized breast milk intake volumes was applied to predict infant exposures and determine the upper area under the curve ratio (UAR). RESULTS: Fifteen breast milk samples from two maternal-infant pairs were collected. The developed liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay showed an analytical range of 0.039-5.0 ng/mL and 0.39-50.0 ng/mL for ezetimibe and EZE-glucuronide, respectively. The measured concentrations in the breast milk samples were 0.17-1.02 ng/mL and 0.42-2.65 ng/mL of ezetimibe and EZE-glucuronide, respectively. The evaluated pediatric PBPK model demonstrated minimal exposure overlap in adult therapeutic dose and breastfed infant simulated area under the concentration-time curve from time zero to 24 h (AUC24). Calculated UAR across infant age groups ranged from 0.0015 to 0.0026. CONCLUSIONS: PBPK model-predicted ezetimibe and EZE-glucuronide exposures and UAR suggest that breastfeeding infants would receive non-therapeutic exposures. Future work should involve a 'mother-infant pair study' to ascertain breastfed infant plasma ezetimibe and EZE-glucuronide concentrations to confirm the findings of this work.

Objectives: Approximately 17% of Japanese women have hemoglobin concentrations less than 12 g/dL. Therefore, anemia prevention and early intervention are crucial public health issues in Japan. This study aimed to identify the symptoms and characteristics of anemic individuals in the general adult population by comparing survey responses of individuals with anemia and without anemia visiting blood donation centers. Materials and Methods: This cross-sectional study used self-administered questionnaires. Individuals who visited two Japanese Red Cross Society blood donation centers in Fukushima Prefecture, Japan were included. Hemoglobin levels were measured at blood donation, and the levels of 13 g/dL for men and 12 g/dL for women were defined as anemia. Results: Of the 857 individuals analyzed, 530 were men and 327 were women, of whom 19 (3.6%) and 12 (3.7%) had low hemoglobin levels, respectively. Logistic regression analysis was performed in men, and the results showed that "lightheadedness" (odds ratio [OR]=8.4) and "depressive symptoms" (OR=3.6) were significantly associated with hemoglobin levels. None of the evaluated items were significantly associated with hemoglobin levels in women. Conclusion: Among healthy Japanese men, those who exhibit lightheadedness and depressive symptoms have an increased risk of anemia. Lightheadedness and depressive symptoms may be indicative of undiagnosed anemia in men, which necessitates greater clinical attention.
