RESUMO
Poor medication compliance in children can affect treatment efficacy. We examined the impact of a picture book created by pharmacists to improve medication compliance in children. Our study aim was to assess the effects of the pharmacist-created picture book on medication compliance in children and their parents in collaboration with an outpatient pharmacy. This study included 74 children (recovery rate 28/74 (37.8%)) aged 3-6 years and their parents between March 2023 and March 2024. In the item "Have you experienced any difficulties in giving medication to your child?" the proportion of respondents answering, "Always" or "Sometimes" decreased from 78.3% (18/23) to 34.7% (8/23) after reading the picture book (p<0.01). When answering the question "What specific situations have you found challenging when giving medication?" the number of responses decreased from (an average/mean) of 1.5 situations before reading the picture book to 1 situation. Regarding whether guardians felt a greater appreciation for the importance of giving medication to their children after reading the book, 64.3% answered "Yes," the highest response. A positive correlation (correlation coefficient=0.77, p<0.01) was observed between "Is the child interested in taking the medication?" and "Is the child able to take the medicine? Pharmacists need to raise public awareness of the importance of medication adherence. Since picture books are likely to be repeatedly read aloud, they are considered effective. The results of this study suggest that pharmacist-created picture books may contribute to improving medication compliance in children.
RESUMO
PURPOSE: Oral mucositis is a severe adverse event in patients undergoing chemotherapy and radiotherapy that may lead to the termination of cancer treatment. This study aimed to elucidate the relationship between salivary inflammatory mediators and oral mucositis in patients undergoing chemotherapy. METHODS: This prospective cohort study included 167 patients who underwent chemotherapy at our institution between June 2020 and November 2023. We evaluated the association between chemotherapy-induced oral mucositis and salivary inflammatory mediators using multiple comparison tests and logistic regression analyses. RESULTS: Of the 167 patients, 67 (40.1%) had oral mucositis. Dunn's multiple comparison test revealed that interleukin-6 was significantly higher in oral mucositis of grades 2 and ≥ 3 (P < 0.01) and tumor necrosis factor (TNF)-α was significantly higher in oral mucositis of grades 3-4 (P < 0.01). Logistic regression analysis showed that the risk of oral mucositis was significantly higher for tumor necrosis factor (TNF)-α > 4.4 pg/mL than for TNF-α ≤ 4.4 pg/mL (adjusted odds ratio, 2.4; 95% confidence interval, 1.1-5.3; P = 0.03). CONCLUSION: Saliva is useful in evaluating inflammation in patients with chemotherapy-induced oral mucositis. Furthermore, TNF-α may be a predictive marker for the severity of oral mucositis in patients undergoing chemotherapy.

BACKGROUND: Dialysis patients undergoing transcatheter aortic valve replacement (TAVR) generally have poor prognosis compared with non-dialysis patients. Furthermore, there are few reliable risk models in this clinical setting. Therefore, we aimed to establish a risk model in dialysis patients undergoing TAVR that would be informative for their prognosis and the decision-making process of TAVR. METHODS: A total 118 dialysis patients (full cohort) with severe aortic stenosis underwent TAVR in our institute between 2012 and 2022. The patients of the full cohort were randomly assigned to two groups in a 2:1 ratio to form derivation and validation cohorts. Risk factors contributing to deaths were analyzed from the preoperative variables and a risk model was established from Cox proportional hazard model. RESULTS: There were 69 deaths following TAVR derived from infectious disease (43.5â¯%), cardiovascular-related disease (11.6â¯%), cerebral stroke or hemorrhage (2.9â¯%), cancer (1.4â¯%), unknown origin (18.8â¯%), and others (21.7â¯%) during the observational period (811⯱â¯719â¯days). The cumulative overall survival rates using the Kaplan-Meier method at 1â¯year, 3â¯years, and 5â¯years in the full cohort were 82.8â¯%, 41.9â¯%, and 24.2â¯%, respectively. An optimal risk model composed of five contributors: peripheral vascular disease, serum albumin, left ventricular ejection fractionâ¯<â¯40â¯%, operative age, and hemoglobin level, was established. The estimated C index for the developed models were 0.748 (95â¯% CI: 0.672-0.824) in derivation cohort and 0.705 (95â¯% CI: 0.578-0.832) in validation cohort. The prediction model showed good calibration [intraclass correlation coefficientâ¯=â¯0.937 (95%CI: 0.806-0.981)] between actual and predicted survival. CONCLUSIONS: The risk model was a good indicator to estimate the prognosis in dialysis patients undergoing TAVR.
RESUMO
Breast milk contains numerous factors that are involved in the maturation of the immune system and development of the gut microbiota in infants. These factors include transforming growth factor-ß1 and 2, immunoglobin A, and lactoferrin. Breast milk factors may also affect epidermal differentiation and the stratum corneum (SC) barrier in infants, but no studies examining these associations over time during infancy have been reported. In this single-center exploratory study, we measured the molecular components of the SC using confocal Raman spectroscopy at 0, 1, 2, 6, and 12 months of age in 39 infants born at our hospital. Breast milk factor concentrations from their mothers' breast milk were determined. Correlation coefficients for the two datasets were estimated for each molecular component of the SC and breast milk factor at each age and SC depth. The results showed that breast milk factors and molecular components of the SC during infancy were partly correlated with infant age in months and SC depth, suggesting that breast milk factors influence the maturation of the SC components. These findings may improve understanding of the pathogenesis of skin diseases associated with skin barrier abnormalities.

Background: The effectiveness of slow low-dose oral immunotherapy (SLOIT) for cow's milk (CM) allergy has been reported. Most OIT studies have discussed the target populations over 4 years old. Furthermore, no predicting modeling is reported for CM allergy remission by CM-SLOIT under 4 years of age. Objective: We sought to develop a predictive model for CM allergy remission by SLOIT after 3 years in young children who started CM-SLOIT under 4 years of age. Methods: We included young children with cow's milk allergy or cow's milk sensitization (development modeling set with 120 children and validation modeling set with 71 children). We did logistic regression analysis to develop the models. We calculated the area under the receiver operating curves (ROC-AUCs) to evaluate the predictive modeling performance. Results: The model (CM-sIgE before SLOIT + age at beginning SLOIT + serum TARC before starting SLOIT + CM-sIgE titer one year after OIT) showed good discrimination with the ROC-AUC of 0.83 (95% CI:0.76-0.91) on internal validation. Applying the model to the validation set gave good discrimination (ROC-AUC = 0.89, 95% CI:0.80-0.97) and a reasonable calibration (intraclass correlation coefficient = 0.88, 95% CI:0.62-0.97). Conclusion: We developed and validated predictive modeling for determining the remission rate of CM allergy at 3 years after SLOIT under 4 years of age in children with CM allergy. This predictive model is highly accurate and can support CM allergy management. (226 words).
RESUMO
INTRODUCTION: Our study was conducted to determine factors associated with the effectiveness of a ß-blocker eye drop add-on in altering pulse rate (PR) in glaucoma patients. METHODS: This retrospective study examined 236 eyes of 138 patients who received a ß-blocker eye drop add-on during follow-up. Patients were included if at least one PR measurement was available both before and after the add-on was started. We collected data on ophthalmic parameters: longitudinal PR; longitudinal choroidal blood flow, represented by laser speckle flowgraphy-measured mean blur rate (MBR); and diacron-reactive oxygen metabolites (d-ROMs). We used a multivariable linear mixed-effects model to investigate the effectiveness of the ß-blocker eye drop add-on in altering PR and examined factors contributing to a larger PR alteration after the add-on was started by analyzing the effect on PR of the interaction term between the add-on and clinical factors. We used the k-means method to classify the patients. RESULTS: The ß-blocker eye drop add-on reduced PR (- 7.61 bpm, P < 0.001). Female gender, higher PR when the add-on was started, lower central corneal thickness, and a higher d-ROM level were associated with greater reduction in PR (P < 0.05). In a cluster of patients with these clinical features, choroidal MBR increased by + 3.42% when we adjusted for change over time; MD slope, which represents the speed of glaucoma progression, improved by + 0.64 dB/year (P < 0.05). CONCLUSIONS: We identified a glaucoma subgroup in which PR decreased, choroidal blood flow increased, and glaucoma progression slowed after a ß-blocker eye drop add-on was started.

BACKGROUND: Food allergy children and their families tend to have emotional distress and anxiety. There have been few reports of differences in parenting stress and a child's food allergy phenotypes. METHODS: We examined the associations between food allergy phenotypes in children and parenting stress assessed by the Parenting Stress Index-Short Form (PSI-SF) from a national birth cohort (Japan Environment and Children's Study). RESULTS: We included 65,805 children for statistical analysis. Of them, 7.2% of children had a food allergy diagnosis at 2 years old. The means of the total PSI-SF (39.9 ± 10.3, 39.1 ± 9.9), CD-SF (19.5 ± 5.4, 19.1 ± 5.2), and PD-SF (20.5 ± 6.3, 20.0 ± 6.1) scores are similar for caregivers in the with and without food allergy groups. Food allergy diagnosis resulted in significantly higher total PSI scores (coefficient .47, 95% CI 0.19-0.75, p = .001), CD-SF (coefficient .22, 95% CI 0.07-0.38, p = .004), and PD-SF (coefficient .24, 95% CI 0.08-0.41, p = .004). A similar trend was observed for allergy reactions to hen's egg. However, there was no clear relationship between allergic reactions to milk, wheat, nuts, and PSI-SF. CONCLUSIONS: Parental stress was significantly related to a child's food allergy. Furthermore, hen's egg allergy increased parental stress. Multiple food avoidance might also increase parental stress. Healthcare providers need to be aware of parental stress in our daily clinic.

Background Many prenatal factors are reported to be associated with congenital heart defects (CHD) in offspring. However, these associations have not been adequately examined using large-scale birth cohorts. Methods and Results We evaluated a data set of the Japan Environmental and Children's Study. The primary outcome was a diagnosis of CHD by age 2 years. We defined the following variables as exposures: maternal baseline characteristics, fertilization treatment, maternal history of diseases, socioeconomic status, maternal alcohol intake, smoking, tea consumption, maternal dietary intake, and maternal medications and supplements up to 12 weeks of gestation. We used multivariable logistic regression analysis to assess the associations between various exposures and CHD in offspring. A total of 91 664 singletons were included, among which 1264 (1.38%) had CHD. In multivariable analysis, vitamin A supplements (adjusted odds ratio [aOR], 5.78 [95% CI, 2.30-14.51]), maternal use of valproic acid (aOR, 4.86 [95% CI, 1.51-15.64]), maternal use of antihypertensive agents (aOR, 3.80 [95% CI, 1.74-8.29]), maternal age ≥40 years (aOR, 1.59 [95% CI, 1.14-2.20]), and high maternal hemoglobin concentration in the second trimester (aOR, 1.10 per g/dL [95% CI, 1.03-1.17]) were associated with CHD in offspring. Conclusions Using a Japanese large-scale birth cohort study, we found 6 maternal factors to be associated with CHD in offspring.

BACKGROUND: The level of child development may be associated with the risk of poor maternal health-related quality of life (HRQoL). The objective of this study was to describe the developmental characteristics of very low birth weight (VLBW) children at 2.5 years of age and to examine associations between maternal HRQoL and the degree of child development based on the Japanese version of Ages and Stages Questionnaire (J-ASQ-3). METHODS: A cross-sectional study was performed using the data from a nationwide prospective birth cohort study in Japan. Among a total of 104,062 fetal records, the VLBW infants (birth weight ≤ 1500 g) were analyzed using linear regression models, adjusted for potential covariates. Subgroup analysis was also conducted to assess the association between social connection or cooperation of the partner and maternal HRQoL by the level of child development. RESULTS: The final study subjects included 357 VLBW children and mothers. The suspected developmental delays (SDDs) in at least two domains was significantly associated with lower maternal mental HRQoL regression coefficient -2.314 (95%CI: -4.065 to -0.564). There was no association between the status of child development and maternal physical HRQoL. After adjusting for child and maternal covariates, the maternal HRQoL was not significantly associated with child development. Amongst women who indicated having some social support, having a child with a SDD in two or more domains was negatively associated with mental HRQoL compared with women whose child was less developmental delay, regression coefficient -2.337 (95%CI: -3.961 to -0.714). Amongst women who indicated having partner's cooperation to child-rearing, having a child with a SDD in two or more domains was negatively associated with mental HRQoL compared with women whose child was less developmental delay, regression coefficient -3.785 (95%CI: -6.647 to -0.924). CONCLUSIONS: Our findings indicate that the lower maternal mental HRQoL was independently associated with the SDDs evaluated by the J-ASQ-3, whereas there was no association after adjusting for covariates. Further research is warranted to elucidate the impact of social connection and partner's cooperation on maternal HRQoL and child development. This study urges that particular attention should be paid to mothers of VLBW children with SDDs and also to provide early intervention and continued support.

BACKGROUND: Reference blood pressure (BP) values for Japanese children based on a large number of measurements by auscultation have not yet been established. METHODS: This was a cross-sectional analysis of data from a birth-cohort study. The data from the sub-cohort study conducted for children at the age of 2 years in the Japan Environment and Children's Study from April 2015 to January 2017 were analyzed. BP was measured via auscultation using an aneroid sphygmomanometer. Each participant was measured in triplicate, and the average value of two consecutive measurements with a difference of less than 5 mmHg was recorded. The reference BP values were estimated using the lambda-mu-sigma (LMS) method and compared with those obtained via the polynomial regression model. RESULTS: Data from 3361 participants were analyzed. Although the difference between the estimated BP values by the LMS and the polynomial regression model was small, the LMS model was more valid based on the results of the fit curve of the observed values and regression models for each model. For 2-year-old children with heights in the 50th percentile, the 50th, 90th, 95th, and 99th percentile reference values of systolic BP (mmHg) for boys were 91, 102, 106, and 112, and that for girls were 90, 101, 103, and 109, respectively, and those of diastolic BP for boys were 52, 62, 65, and 71, and that for girls were 52, 62, 65, and 71, respectively. CONCLUSION: The reference BP values for 2-year-old Japanese children were determined based on auscultation and were made available.

PURPOSE: Oral mucositis is a severe adverse event in patients with head and neck cancer (HNC) receiving chemotherapy and radiotherapy that may cause the termination of cancer treatment. In this study, we aimed to reveal the benefits of pharmacist interventions in oral health care for patients with HNC receiving concurrent chemoradiotherapy (CCRT). METHODS: We conducted a multicenter, prospective cohort study on 173 patients from September 2019 to August 2022. We evaluated the association between the occurrence of oral mucositis during CCRT and various factors in the absence or presence of direct medication instructions from hospital pharmacists. RESULTS: Sixty-eight patients received medication instructions from pharmacists (the pharmacist intervention group), whereas 105 patients did not receive instructions (the control group). Logistic regression analysis showed that grade 2 (Gr 2) oral mucositis was significantly lower in patients receiving pharmacist interventions than in patients in the control group (adjusted odds ratio [aOR], 0.42; 95% confidence interval [CI], 0.18-0.96; P = 0.04). The time to onset of Gr 2 oral mucositis was significantly longer in the pharmacist intervention group than in the control group (hazard ratio, 0.53; 95% CI, 0.29-0.97; P = 0.04). CONCLUSION: Direct intervention, especially when provided by hospital pharmacists, can have a real effect in supporting patients with HNC experiencing severe side effects of treatments. Moreover, the integration of pharmacists into the oral healthcare team is becoming even more essential to reduce the severity of side effects.

BACKGROUND: Physiological skin properties of neonates and infants change drastically after birth and are implicated in the onset of atopic dermatitis and other diseases. Studies have measured physiological skin properties in infants; however, how these properties change over time remains unclear. No reports have measured ceramide in the stratum corneum of infants using confocal Raman spectroscopy; hence, we used it to measure the physiological properties of the skin, including ceramide, in infants. MATERIALS AND METHODS: The water content and other factors in the skin of infants aged 0, 1, and 6 months were measured. All measurements were performed five times indoors at 22 ± 2°C and 50% ± 10% relative humidity in the middle of the calf at 4-µm distances, and their mean was calculated. RESULTS: The water content of the area between the skin surface and superficial layers was the lowest in newborns as compared with other ages, and the deeper the skin layer, the higher the water content. The stratum corneum, evaluated using confocal Raman spectroscopy, was the thickest in newborns and gradually thinned with age. Its water content was the lowest in newborns. The levels of natural moisturizing factor, ceramide, and cholesterol were higher in newborns and tended to decrease with age. CONCLUSION: This report is the first to evaluate ceramide in the stratum corneum of infants using confocal Raman spectroscopy and could help in conducting subsequent longitudinal measurements of physiological skin properties in neonates and infants.

The influence of family allergic history on food allergy in offspring in Japan is unknown. We analyzed data from a nationwide birth cohort study using logistic regression models to examine the associations of maternal, paternal, and both parental histories of allergic diseases (food allergy, atopic dermatitis, asthma, and rhinitis) with their child's food allergy at 1.5 and 3 years of age. This analysis included 69,379 singleton full-term mothers and 37,179 fathers and their children. All parental histories of allergic diseases showed significant positive associations with their child's food allergy. When both parents had a history of allergic diseases, the adjusted odds ratio (aOR) tended to be higher than when either parent had allergic diseases (p for trend < 0.0001). The highest aOR was detected when both parents had food allergy (2.60; 95% confidential interval, 1.58−4.27), and the aOR was 1.71 when either parent had food allergy (95% confidential interval, 1.54−1.91). The aORs were attenuated but still had significant positive associations after adjusting for the child's atopic dermatitis, a risk factor for allergy development. In conclusion, all parental allergic diseases were significantly positively associated with their child's food allergy. The effect of family history showed a stepwise increase in risk from either parent to both parents, and the highest risk of allergic disease was a parental history of food allergy.

BACKGROUND: Glaucoma is multifactorial, but the interrelationship between risk factors and structural changes remains unclear. Here, we adjusted for confounding factors in glaucoma patients with differing risk factors, and compared differences in structure and susceptible areas in the optic disc and macula. METHODS: In 458 eyes with glaucoma, we determined confounding factors for intraocular pressure (IOP), central corneal thickness (CCT), axial length (AL), LSFG-measured ocular blood flow (OBF), which was assessed with laser speckle flowgraphy-measured mean blur rate in the tissue area (MT) of the optic nerve head, biological antioxidant potential (BAP), and systemic abnormalities in diastolic blood pressure (dBP). To compensate for measurement bias, we also analyzed corrected IOP (cIOP; corrected for CCT) and corrected MT (cMT; corrected for age, weighted retinal ganglion cell count, and AL). Then, we determined the distribution of these parameters in low-, middle-, and high-value subgroups and compared them with the Kruskal-Wallis test. Pairwise comparisons used the Steel-Dwass test. RESULTS: The high-cIOP subgroup had significantly worse mean deviation (MD), temporal, superior, and inferior loss of circumpapillary retinal nerve fiber layer thickness (cpRNFLT), and large cupping. The low-CCT subgroup had temporal cpRNFLT loss; the high-CCT subgroup had low cup volume. The high-AL subgroup had macular ganglion cell complex thickness (GCCT) loss; the low-AL subgroup had temporal cpRNFLT loss. The high-systemic-dBP subgroup had worse MD, total, superior, and inferior cpRNFLT loss and macular GCCT loss. The low-BAP subgroup had more male patients, higher dBP, and cpRNFLT loss in the 10 o'clock area. The high-OBF subgroup had higher total, superior and temporal cpRNFLT and macular GCCT. CONCLUSIONS: Structural changes and local susceptibility to glaucomatous damage show unique variations in patients with different risk factors, which might suggest that specific risk factors induce specific types of pathogenesis and corresponding glaucoma phenotypes. Our study may open new avenues for the development of precision medicine for glaucoma.

Colostrum is the first food for newborns and it contains various crucial immune factors. The concentrations of immune factors in breast milk may change depending on maternal characteristics such as body mass index, collection day, and age at first pregnancy. In this exploratory study, we investigated the association between TGF-ß1, TGF-ß2, and IgA in colostrum and rarely studied factors that affect breast milk components, including the use of labor-inducing medication, colostrum secretion, sex of newborns, breast or nipple problems, and nipple care. Breast milk samples were collected from 42 mothers and analyzed for TGF-ß1, TGF-ß2, and IgA. The results suggest that parity and mode of delivery may be correlated with the concentrations of immune factors in colostrum. However, we found no association between the immune factors in colostrum and the use of labor-inducing medications, colostrum secretion, sex of newborns, breast or nipple problems, and nipple care. These findings have some implications for further analysis of the effects of immune factors in breast milk on the prognosis of allergies in children.

Background: Atopic dermatitis (AD) is a chronic and inflammatory skin disease that causes health-related burdens associated with pruritus and poor quality of life. Our previous study demonstrated that moisturizer (2e) application has a primary preventive effect on AD. However, this effect was not observed in recent randomized control trials. Thus, the ideal moisturizer type and application frequency for preventing AD development in infants remains unclear. We hypothesize that twice daily application of moisturizer is more effective than once daily application. We predict that applying sufficient amounts of high-quality moisturizer may be effective for preventing AD development in neonates and infants. Here, we describe a protocol for comparing the efficacy of twice daily and once daily application of Fam's Baby™ moisturizer and once daily application of 2e moisturizer for preventing AD in neonates. Methods: This study is a single-center, three-parallel group, assessor-blind, superiority, individually randomized, controlled, phase II trial. Sixty newborns with at least one parent or sibling who has had AD is randomly assigned to application of Fam's Baby twice daily, Fam's Baby once daily, or 2e once daily in a 1:1:1 ratio until 32 weeks old. The primary outcome is the time to the first onset of AD during administration of the moisturizer. Discussion: This is the first phase II randomized, controlled trial in Japan to estimate how effective the twice daily or once daily application of Fam's Baby moisturizer is in preventing AD compared to the once daily application of 2e moisturizer. In this study, we will use 2e once daily as a control to confirm the efficacy for primary prevention of AD as found in our previous trial. Based on the results of this study, we hope to conduct a phase III study to determine the optimal method for preventing AD via moisturizer application. Evaluation of application of moisturizers for preventing AD in this study is expected to contribute to a reduction in the prevalence of AD and a reduction in health care costs.

RESUMO
BACKGROUND: The role of antibiotics in the treatment of Shiga toxin-producing Escherichia coli (STEC) infection is controversial. OBJECTIVES: To evaluate the association between treatment (antibiotics, antidiarrheal agents, and probiotics) for STEC infection and hemolytic uremic syndrome (HUS) development. PATIENTS AND METHODS: We performed a population-based matched case-control study using the data from the National Epidemiological Surveillance of Infectious Diseases (NESID) between January 1, 2017 and December 31, 2018. We identified all patients with STEC infection and HUS as cases and matched patients with STEC infection without HUS as controls, with a case-control a ratio of 1:5. Further medical information was obtained by a standardized questionnaire. Multivariable conditional logistic regression model was used. RESULTS: 7760 patients with STEC infection were registered in the NESID. 182 patients with HUS and 910 matched controls without HUS were selected. 90 patients with HUS (68 children and 22 adults) and 371 patients without HUS (266 children and 105 adults) were included in the main analysis. The matched ORs of any antibiotics and fosfomycin for HUS in children were 0.56 (95% CI 0.32-0.98), 0.58 (0.34-1.01). The matched ORs for HUS were 2.07 (1.07-4.03), 0.86 (0.46-1.61) in all ages treated with antidiarrheal agent and probiotics. CONCLUSIONS: Antibiotics, especially fosfomycin, may prevent the development of HUS in children, while use of antidiarrheal agents should be avoided.
