RESUMO
ObjectivesãThe relationship between household income and dietary intake among older children and adults in Japan has been studied. However, few studies have examined the relationship in younger children, and we believe that this should be taken into consideration from early childhood to correct health disparities. In this study, we examined the relationship between family income and dietary food group intake, and investigated the adequacy of food intake based on the Japanese Food Guide Spinning Top for young children aged 3 to 6 years attending nursery school. The goal of this study was to obtain trends in food intake that can be used to improve poor dietary intake of young children caused by socioeconomic factors.MethodsãA dietary survey using the food weighing or recording method and a self-administered questionnaire on dietary status were conducted on two non-consecutive days, including weekdays and weekends, from October to December 2019 or 2020. The participants were 761 young children (423 boys and 338 girls) attending nursery schools in seven cities in Japan. Equivalent income was calculated from household income and the number of family members indicated in the dietary status survey. Intake of each food group and consistency with the Japanese Food Guide Spinning Top were compared in five quintiles.ResultsãCompared to the low equivalent income group, the high equivalent income group showed a decreasing trend in cereal intake and an increasing trend in the intake of sugar and sweeteners, green and yellow vegetables, and dairy products. The percentage of the low-income group who did not meet the definition of adequate intake using the Japanese Food Guide Spinning Top was lower for meals that include cereals and grain products, and higher for meals that include meat and fish, vegetable, milk and dairy products, and fruits.ConclusionãThe lower income group had higher intake of cereals and lower intake of vegetables and fruits compared to the higher income group. This finding is similar to the results of studies in adults and older children. However, based on the Japanese Food Guide Spinning Top, >90% of young children have a diet that fall below the adequate intake of meals, including vegetable dishes and even on weekdays, which suggests a general vegetable deficiency in young children. Multifaceted support is required to address this concern, including measures to correct disparities of income and to ensure desirable nutrient intake in early childhood.

Importance: It is unknown whether olanzapine combined with triplet antemetic therapy is effective for all patients undergoing highly emetogenic chemotherapy. A secondary analysis of randomized clinical trials using olanzapine may provide insight into the effectiveness of olanzapine for chemotherapy-induced nausea and vomiting (CINV), including cisplatin. Objective: To examine the add-on effect of olanzapine according to risk factors for CINV. Design, Setting, and Participants: This preplanned secondary analysis evaluated results of the J-FORCE trial, a large double-blind, placebo-controlled phase 3 randomized clinical trial conducted in Japan from February 9, 2017, to July 18, 2018. Participants were enrolled from 26 participating hospitals across Japan and included patients aged 20 to 75 years who had a malignant tumor and were cisplatin-naive. The efficacy analysis population of the J-FORCE trial was analyzed according to allocation adjustment factors (sex [male or female], age [≥55 years or <55 years], and cisplatin dose [≥70 mg/m2 or <70 mg/m2]) and patient-related risk factors (history of motion sickness, drinking habit [defined as alcoholic drinks consumption in excess of occasional drinking], and history of morning sickness during pregnancy). Statistical analysis was performed from February 18 to April 18, 2020. Interventions: Patients were randomized 1:1 to receive 5 mg of olanzapine or placebo combined with standard triplet antiemetic therapy. Main Outcomes and Measures: The primary end point was complete response (CR, defined as no vomiting and no use of rescue medication) in the delayed phase (24-120 hours after cisplatin-based chemotherapy administration). Secondary end points were CR, complete control, and total control in the acute, delayed, and overall phases for 6 CINV risk factors as well as time to treatment failure. The CR point estimates and 95% CIs of the differences between groups were calculated, and a Mantel-Haenszel test was performed. Results: Of the 705 patients (mean [SD] age, 63.0 [9.2] years; 471 males [66.8%]) included in the efficacy analysis population; 581 patients (82.4%) were 55 years or older, and 526 (74.6%) were treated with a cisplatin dose of 70 mg/m2 or more. Risk difference (RD) for a CR in the delayed phase was significantly greater in the olanzapine group than the placebo group in males (RD, 12.6% [95% CI, 5.0%-20.1%]; P = .001); in females (RD, 14.5% [95% CI, 2.2%-26.3%]; P = .02); in those 55 years or older (RD, 11.1% [95% CI, 3.9%-18.2%]; P = .003) or younger than 55 years (RD, 23.6% [95% CI, 7.3%-38.3%]; P = .005); for a cisplatin dose of 70 mg/m2 or more (RD, 13.5% [95% CI, 5.9%-21.0%]; P < .001); for those without a history of motion sickness (RD, 13.9% [95% CI, 6.9%-20.6%]; P < .001); for those with a drinking habit (RD, 14.9% [95% CI, 6.1%-23.4%]; P = .001) or without a drinking habit (RD, 12.0% [95% CI, 2.5%-21.3%]; P = .01); and for those with a history of morning sickness during pregnancy (RD, 27.2% [9.7%-42.6%]; P = .002). In other subgroups, a delayed CR was higher in the olanzapine group than the placebo group, although not significantly higher. Conclusions and Relevance: Results of this study suggest a benefit of using 5 mg of olanzapine plus triplet antiemetic therapy to counter CINV regardless of the presence or absence of risk factors.

INTRODUCTION: Triple antiemetic therapy with neurokinin-1 receptor antagonist, 5-hydroxytryptamine type 3 receptor antagonist, and dexamethasone has been widely recommended for high emetogenic chemotherapeutic (HEC) agents and regimens, including anthracycline combined with cyclophosphamide (AC). The addition of olanzapine (OLZ) 5 mg or 10 mg to the recommended triple antiemetic therapy has demonstrated superiority in antiemetic efficacy compared with the standard triplet therapy for a cisplatin-based HEC regimen. Although OLZ plus the triple antiemetic treatment may also be effective for patients on an AC-based HEC regimen, no study has investigated its efficacy at a lower dose of 5 mg. METHODS AND ANALYSIS: To assess whether 5 mg OLZ, as compared with placebo, in combination with triple combination therapy, significantly improves nausea and vomiting, we are conducting a randomised, parallel-group controlled clinical trial with a total of 500 patients at 15 study centres in Japan. The primary outcome is the complete response rate, defined as no emetic episodes and no use of rescue medication during 120 hours after the initiation of chemotherapy. Treatment group comparison for the primary endpoint will be done by using the Cochran-Mantel-Haenszel test. ETHICS AND DISSEMINATION: The study was approved by the institutional review board of Juntendo University Hospital and relevant approval was obtained from all participating centres. All participants will be required to provide written informed consent. The trial results will be reported at conferences and in peer-reviewed journals.

Objective We aimed to examine the effects of isometric handgrip (IHG) training on home blood pressure (BP) levels in hypertensive Japanese patients undergoing treatment. Methods Fifty-three hypertensive patients (mean age, 61.7 years; 56.6% men) with a home systolic BP ≥135 mmHg and/or a home diastolic BP ≥85 mmHg were randomly assigned to either group A or B. As per the crossover design, group A performed 8 weeks of IHG training, followed by an equivalent training-free, control period, while the reverse protocol was performed by group B. The baseline characteristics were similar between both groups. The individualized daily IHG training comprised four sets of 2-min isometric contractions at 30% of the individual's maximum voluntary contraction capacity, including 1 min of rest between sets, for ≥3 days/week. The outcome measure was morning and evening home BP readings taken over the last 2 weeks of the training and control periods. Results A combined data analysis for both groups showed that IHG training was significantly associated with the lowering of both systolic and diastolic BP in the morning (137.9±9.3 vs. 135.3±9.5 mmHg, p=0.007 and 83.0±9.5 vs. 81.2±9.3 mmHg, p<0.001, respectively) and evening (130.0±10.7 vs. 127.6±10.1 mmHg, p=0.003 and 75.8±10.4 vs. 73.8±9.2 mmHg, p<0.001, respectively), while no significant change was observed after the control period. A larger increase in the maximum grip strength due to IHG training was associated with greater BP reductions. Conclusion An 8-week period of IHG training significantly lowered both the morning and evening home BP in hypertensive Japanese patients undergoing treatment.

PURPOSE: Skin toxicities associated with anti-epidermal growth factor receptor(EGFR)antibodies, have a profound effect on the continuation of treatment. We assessed the efficacy and safety of vitamin K1(VK1)ointment for acneiform eruptions induced by anti-EGFR antibody treatment. METHODS: The VK1 ointment was applied to one-half of an affected area and placebo ointment was applied to the other half twice a day for 8 weeks, with photography and clinical evaluation being performed every 2 weeks. The primary endpoint was the change of the VK1/placebo ratio for the number of acneiform eruptions counted by an independent dermatologist between the onset and end of the treatment period. RESULTS: A total of 30 patients were enrolled. The mean VK1/placebo ratio for the number of acneiform eruptions between the onset and end of the treatment period was -0.158±0.680 and 0.146±0.575, respectively, which was not statistically significant(p=0.069). The mean number of acneiform eruptions at each treatment period at the VK1 and placebo application sites was gradually decreased according to the treatment period. CONCLUSION: VK1 ointment was not effective against acneiform eruptions induced by treatment with cetuximab or panitumumab. Reassessment of the VK1 concentration in the ointment and the endpoint of skin lesions is required before designing further studies.

BACKGROUND: Olanzapine 10 mg added to standard antiemetic therapy including aprepitant, palonosetron, and dexamethasone has been recommended for the prevention of chemotherapy-induced nausea and vomiting. Guidelines suggest that a dose reduction to 5 mg should be considered to prevent sedation. In several phase 2 studies, olanzapine 5 mg has shown equivalent activity to olanzapine 10 mg and a favourable safety profile in relation to somnolence. We evaluated the efficacy of olanzapine 5 mg combined with standard antiemetic therapy for the prevention of chemotherapy-induced nausea and vomiting caused by cisplatin-based chemotherapy. METHODS: This was a randomised, double-blind, placebo-controlled, phase 3 study to evaluate the efficacy of olanzapine 5 mg with triplet-combination antiemetic therapy done in 26 hospitals in Japan. Key inclusion criteria were patients with a malignant tumour (excluding those with a haemopoietic malignancy) who were scheduled to be treated with cisplatin (≥50 mg/m2) for the first time, age between 20 and 75 years, and with Eastern Cooperative Oncology Group performance status of 0-2. Eligible patients were randomly assigned (1:1) to receive either oral olanzapine 5 mg or placebo once daily on days 1-4 combined with aprepitant, palonosetron, and dexamethasone (dosage based on the standard antiemetic therapy against highly emetogenic chemotherapy). Patients were randomly assigned to interventions by use of a web entry system and the minimisation method with a random component, with sex, dose of cisplatin, and age as factors of allocation adjustment. Patients, medical staff, investigators, and individuals handling data were all masked to treatment assignment. The primary endpoint was the proportion of patients who achieved a complete response, defined as absence of vomiting and no use of rescue medications in the delayed phase (24-120 h). All randomly assigned patients who satisfied eligibility criteria received a dose of cisplatin 50 mg/m2 or more, and at least one study treatment, were included in efficacy analysis. All patients who received any treatment in this study were assessed for safety. This study is registered at UMIN Clinical Trials Registry, number UMIN000024676. FINDINGS: Between Feb 9, 2017, and July 13, 2018, 710 patients were enrolled; 356 were randomly assigned to receive olanzapine and 354 were assigned to receive placebo. All eligible patients were observed 120 h after cisplatin initiation. One patient in the olanzapine group and three in the placebo group did not receive treatment and were excluded from all analyses. One patient in the olanzapine group discontinued treatment on day 1 and was excluded from the efficacy analysis. In the delayed phase, the proportion of patients who achieved a complete response was 280 (79% [95% CI 75-83] of 354 patients in the olanzapine group and 231 (66% [61-71] of 351 patients in the placebo group (p<0·0001). One patient had grade 3 constipation and one patient had grade 3 somnolence related to treatment in the olanzapine group. INTERPRETATION: Olanzapine 5 mg combined with aprepitant, palonosetron, and dexamethasone could be a new standard antiemetic therapy for patients undergoing cisplatin-based chemotherapy.
