Background: Datopotamab deruxtecan (Dato-DXd) is an antibody-drug conjugate (ADC) consisting of a humanized anti-TROP2 IgG1 monoclonal antibody covalently linked to a highly potent topoisomerase I (Topo I) inhibitor payload via a stable, tumor-selective, tetrapeptide-based cleavable linker. Dato-DXd demonstrated compelling single-agent antitumor activity in heavily pretreated patients (pts) with metastatic triple-negative BC (Krop, SABCS 2021). This is the first report of results from the TROPION-PanTumor01 study in pts with unresectable or metastatic hormone receptor–positive (HR+)/human epidermal growth factor receptor 2–negative (HER2−; including HER2-low and HER2-zero) BC. Methods: TROPION-PanTumor01 (NCT03401385) is a phase 1, multicenter, open-label, 2-part dose-escalation/expansion study evaluating Dato-DXd in previously treated pts with solid tumors. Based on previous clinical findings and exposure-response results from pts with NSCLC, Dato-DXd 6 mg/kg IV Q3W is being evaluated in pts with unresectable or metastatic HR+/HER2− BC that progressed on standard therapies. The primary objectives were safety and tolerability. Tumor responses, including ORR (complete response [CR] + partial response [PR]) and DCR (CR + PR + stable disease [SD]), were assessed per RECIST version 1.1 by blinded independent central review. Results: As of the April 29, 2022, data cutoff, 41 pts had received Dato-DXd (median follow-up, 10.9 mo [range, 7-13]); 9 pts were ongoing. The primary cause of treatment discontinuation was disease progression (63%; progressive disease [PD] or clinical progression). Median age was 57 y (range, 33-75); 54% had de novo metastatic disease. Pts were heavily pretreated (Table) with a median of 5 (range, 3-10) prior regimens in the advanced setting; 95% had prior CDK4/6i (adjuvant/metastatic). Median time from initial treatment for metastatic disease to the first dose of Dato-DXd was 42.7 mo (range, 10.2-131.1). Treatment-emergent adverse events (TEAEs; all cause) were observed in 98% (any grade) and 41% (grade ≥3) of pts. Most common TEAEs (any grade, grade ≥3) were stomatitis (80%, 10%), nausea (56%, 0%), fatigue (46%, 2%), and alopecia (37%, 0%). Serious TEAEs were observed in 6 pts (15%); 1 pt died due to dyspnea, which was not considered to be treatment related. Dose reductions occurred in 5 pts due to stomatitis (n=3), fatigue (n=2), keratitis (n=1), and decreased appetite (n=1) (>1 AE per pt); 14 pts had treatment delayed due to stomatitis (n=8), retinopathy (n=1), dysphagia (n=1), fatigue (n=1), malaise (n=1), COVID-19 (n=1), cellulitis (n=1), urinary tract infection (n=1), decreased lymphocyte count (n=1), and nasal congestion (n=1; >1 AE per pt). Three pts discontinued treatment due to keratitis (n=1) and pneumonitis (n=2); 1 case of pneumonitis was adjudicated as grade 2 drug-related interstitial lung disease. The ORR was 29% (11 confirmed PRs; 1 pending confirmation), the DCR was 85% (35/41), and the clinical benefit rate (CR + PR + SD ≥6 mo) was 41% (17/41). Conclusions: Dato-DXd demonstrated a manageable safety profile and encouraging antitumor activity, with high disease control in heavily pretreated pts, the majority having received prior CDK4/6i. Based on these findings, the TROPION-Breast01 (NCT05104866) randomized phase 3 study comparing 2L+ Dato-DXd vs investigator’s choice chemotherapy is currently enrolling pts with HR+/HER2− BC.

Background: Datopotamab deruxtecan (Dato-DXd) is an antibody-drug conjugate (ADC) consisting of a humanized anti-TROP2 IgG1 mAb covalently linked to a highly potent topoisomerase I (Topo I) inhibitor payload via a stable, tumor selective, tetrapeptide-based cleavable linker. Dato-DXd has previously shown encouraging activity in heavily pretreated patients (pts) with metastatic TNBC (Krop, SABCS 2021). Here we report updated results from the TROPION-PanTumor01 study in pts with advanced/metastatic TNBC. Methods: TROPION-PanTumor01 (NCT03401385) is a phase 1, multicenter, open-label, 2-part dose-escalation/expansion study evaluating Dato-DXd in previously treated pts with solid tumors. Based on previous clinical and exposure-response results from pts with NSCLC, Dato-DXd 6 mg/kg IV Q3W is being evaluated in pts with advanced TNBC that relapsed/progressed on standard therapies; 2 pts received 8 mg/kg prior to selection of 6 mg/kg. The primary objectives were safety and tolerability. Tumor responses, including objective response rate (ORR; complete response [CR] + partial response [PR]) and disease control rate (DCR; CR + PR + stable disease [SD]), were assessed per RECIST v1.1 by blinded independent central review. Results: As of April 29, 2022, 44 pts received Dato-DXd (median follow-up, 16.6 mo [range, 13-22]) at the time of data cutoff. The primary cause of treatment discontinuation was disease progression (86%; PD or clinical progression), and 4 pts are still receiving therapy. Median age was 53 y (range, 32-82); 32% had de novo metastatic disease. Pts were heavily pretreated with a median of 3 (range, 1-10) prior regimens in the metastatic setting. Prior treatments included taxanes (91%), anthracyclines (75%), capecitabine (61%), platinum (52%), immunotherapy (43%), Topo I inhibitor–based ADC therapy (32%), and PARPi (18%). Treatment-emergent adverse events (TEAEs; all cause) occurred in 100% (any grade) and 50% (grade ≥3) of pts, respectively. Most common TEAEs (any grade, grade ≥3) were stomatitis (73%, 11%), nausea (66%, 2%), vomiting (39%, 5%), fatigue (34%, 7%), and alopecia (36%, 0%). One pt had grade 3 decreased neutrophil count; no cases of interstitial lung disease (ILD) or grade ≥3 diarrhea were observed. Serious TEAEs were reported in 9 pts (20%); no deaths associated with adverse events (AEs) were observed. Dose reductions occurred in 8 pts (18%) due to stomatitis (n=3), fatigue (n=2), dry eye (n=1), retinal exudates (n=1), and dysgeusia (n=1); 12 pts (27%) delayed treatment due to stomatitis (n=5), dry eye (n=1), keratitis (n=1), blurred vision (n=1), fatigue (n=1), bronchitis (n=1), skin infection (n=1), musculoskeletal chest pain (n=1), dysgeusia (n=1), chronic obstructive pulmonary disease (n=1), and dyspnea (n=1; >1 AE per pt). One pt (2%) discontinued treatment due to grade 1 pneumonitis (which was centrally adjudicated as not ILD). ORR in all pts was 32% (1 CR, 13 PRs), DCR was 80% (35/44), and clinical benefit rate (CR + PR + SD ≥6 mo) was 34% (15/44). Median duration of response was not yet reached; median progression-free survival (mPFS) was 4.3 mo (95% CI, 3.0-7.3), and median overall survival (mOS) was 12.9 mo (95% CI, 10.1-14.7). In the subset of pts without prior Topo I inhibitor–based ADC therapy and with measurable disease at baseline, ORR was 44% (12/27). Among all pts without prior Topo I inhibitor–based ADC therapy (n=30), mPFS was 7.3 mo (95% CI, 3.0-NE), and mOS was 14.3 mo (95% CI, 10.5-NE). Conclusions: Dato-DXd continues to demonstrate encouraging and durable antitumor activity, along with a manageable safety profile, in heavily pretreated pts with metastatic TNBC. Based on these findings, the phase 3 randomized TROPION-Breast02 (NCT05374512) trial comparing Dato-DXd vs chemotherapy as 1L therapy for pts with metastatic TNBC is currently underway.

This study aimed to describe the association of healthy eating literacy (HEL) with energy, nutrients, and food consumption in young women who had normal and lean weight at a Japanese university, considering their resident status.Cross-sectional data from the Ochanomizu Health Study were used in this study. Participants answered a self-administered, two-part, anonymous survey in 2018 and 2019. A total of 203 female undergraduate students with lean and normal body mass index (BMI) were included in the analysis. Single and stepwise multiple linear regression analysis was used to examine the association of HEL and resident status with healthy food consumption, such as vegetables, fish, and shellfish. The dependent variables were HEL and resident status, and the covariates were age, BMI, and the total metabolic equivalents.The median (25th and 75th percentiles) age, BMI, and total HEL score were 20 (19, 21) years, 20.2 (18.9, 21.3) kg/mThis study provides an insight into the association between HEL and dietary consumption in young women with normal and lean BMI.

Japanese parents and educators teach children to refrain from leaving food in their plates. Their teachings have direct (advising children to refrain from leaving food uneaten) and indirect (meal-related rituals before and after mealtimes) influence in enhancing gratitude for food in daily life. This cross-sectional study aimed to examine 1) the interaction of direct and indirect approaches to avoiding food waste behaviors and 2) the mediation of gratitude for food by preventing such behaviors. Overall, 400 Japanese adults (female: n = 200) responded to a self-administrated anonymous questionnaire survey measuring: the present food waste avoiding behaviors; current gratitude for food; direct and indirect childhood approaches for avoiding food waste behaviors. Participants' mean (standard deviation) age and body mass index were 40.0 (11.6) and 21.9 (3.9), respectively. A significant main effect of the indirect approach and the interaction of direct and indirect approaches were obtained by adjusting the participants' background. Moreover, through mediation analyses with percentile-corrected bootstrap confidence intervals, it was observed that gratitude for food mediated the association between direct and indirect childhood approaches and avoiding food waste behaviors. Despite no information on the current meal-related rituals of the respondents, this study suggests the potential of these approaches in enhancing gratitude for food as a new approach to reduce food waste worldwide.

Background: Datopotamab deruxtecan (Dato-DXd) is an antibody-drug conjugate consisting of a humanized anti-TROP2 IgG1 monoclonal antibody conjugated to a potent topoisomerase I inhibitor payload via a stable tetrapeptide-based cleavable linker. Preliminary results from the phase 1 TROPION-PanTumor01 study demonstrate that Dato-DXd has encouraging antitumor activity and a manageable safety profile in patients with non-small cell lung cancer (NSCLC) (Meric-Bernstam, ASCO 2021) and those with triple-negative breast cancer (TNBC) (Bardia, ESMO BC 2021). Updated results from the TNBC cohort are presented here. Methods: TROPION-PanTumor01 (NCT03401385) is a phase 1, multi-center, open-label, 2-part study evaluating Dato-DXd in previously treated patients with solid tumors. Based on the dose-escalation results in patients with NSCLC, Dato-DXd 6 mg/kg intravenously every 3 weeks is being evaluated in patients with advanced/metastatic TNBC and HR+/HER2− breast cancer who relapsed/progressed on standard therapies. Two patients with TNBC received Dato-DXd 8 mg/kg prior to selection of 6 mg/kg for dose expansion. Safety and efficacy were assessed, including objective response rate (ORR) per RECIST version 1.1 by blinded independent central review (BICR). Results: As of the April 6, 2021, data cutoff, 43 patients with TNBC had received ≥1 dose of Dato-DXd, with 27 patients (63%) continuing and 16 patients (37%) discontinuing treatment all due to disease progression. The median age was 53 years (range, 32-82 years). Forty-one patients (95%) had received ≥2 prior lines of therapy; 19 patients (44%) had received prior immunotherapy and 7 (16%) had received prior sacituzumab govitecan. The median duration of treatment was 2.8 months (range, 0.7-6.9 months). The median follow-up was 3.9 months (range, 0.3-9.2 months). Among 38 patients evaluable for response, the ORR by BICR was 39% (15 partial responses [PR]), with 12 confirmed and 3 pending confirmation. The disease control rate was 84% (32/38). The median time to response was 1.35 months (1.2-3.2 months) for the 12 confirmed PRs. All-cause treatment-emergent adverse events (TEAEs; any grade, grade ≥3) were observed in 95% and 35% of patients, respectively; 2 events were grade 4 and 0 grade 5. The most common TEAEs (any grade [≥30%], grade ≥3) included nausea (58%, 0%), stomatitis (53%, 9%), alopecia (35%, N/A), vomiting (35%, 2%), and fatigue (33%, 7%). One patient had grade 3 decreased neutrophil count; no cases of grade ≥3 diarrhea were observed. No cases of treatment-related interstitial lung disease as adjudicated by an independent committee were reported. Serious TEAEs were observed in 5 patients (12%); no TEAEs were associated with death. Dose reductions occurred in 9 patients due to stomatitis, fatigue, mucosal inflammation, dry eye, retinal exudates, and blurred vision (multiple counts per TEAE). Three patients had dose interruptions due to stomatitis, mucosal inflammation, bronchitis, and musculoskeletal chest pain. No patients discontinued treatment due to adverse events. Conclusions: Preliminary results showed that Dato-DXd demonstrates promising antitumor activity with a manageable safety profile in patients with previously treated advanced/metastatic TNBC; confirmatory studies in patients with breast cancer are warranted.

This study aimed to investigate the correlation between mindful eating and nutritional intake, food consumption, and healthful and unhealthful plant-based dietary patterns in young Japanese women. The sample comprised 215 female undergraduates who responded to a two-questionnaire anonymous survey conducted in Tokyo, Japan in 2018 and 2019 from November to December. We measured mindful eating status using the Expanded Mindful Eating Scale (EMES) and used Japanese plant-based dietary indices to determine plant-based dietary patterns. Partial correlation analyses were conducted to determine the correlation of mindful eating with energy and nutrient intake, food consumption, and plant-based dietary patterns, after adjusting for demographics and body mass index. Participants with higher sub-scores in “health of the planet” and “awareness and appreciation for food” ate higher quantities of several micronutrients and plant-based foods and were more likely to have a healthful plant-based dietary pattern. They were also less likely to have an unhealthful plant-based dietary pattern. In contrast, participants with higher scores in “non-judgmental awareness” ate less protein, whole grains, and vegetables, and were likely to have an unhealthful plant-based dietary pattern. This study is the first to show that young Japanese women with normal or lean body weight were more likely to consume healthful plant-based foods when they ate mindfully. Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

The consumers' Sustainable and Healthy Dietary Behaviors (SHDBs) links sustainable behaviors related to eating (e.g., choosing, cooking, eating, and disposing of foods) with the level of "dietary behavior." It was hypothesized that SHDBs will vary depending on consumers' meal preparation habits, such as food selection, cooking frequency, and skill. This study examined (1) some of the behavioral patterns of SHDBs and (2) independent predictors of each pattern. In total, 508 Japanese adults who completed cross-sectional self-administered questionnaire surveys in December 2021 were included in the study. Principal component analysis (PCA) was used to identify the behavioral patterns of the 30-item SHDBs developed previously by the authors. Additionally, independent predictors of each component score were analyzed using multiple linear regression models, which included demographics, psychological factors concerning SHDBs (pros and cons for the decisional balance of SHDBs and number of environmental issues of interest), and meal preparation habits. Participants' median age was 41 (18-59) years (women: n = 259, 51.0%). Five SHDB patterns with several independent predictors were identified: amalgamation of all SHDBs, healthy food choices but unsustainable cooking, sustainable disposal, avoiding plastic products, and sustainable behaviors regarding expiry date. The multiple linear regression analysis demonstrated the independent predictors of the amalgamation of all SHDBs, such as being a man (β = -0.105), greater pros (β = 0.134), higher cooking frequency (β = 0.443) and skill (β = 0.244). Greater pros and/or smaller cons were associated with four of the five SHDB patterns, including an amalgamation of all SHDBs, healthy food choice and unsustainable cooking, avoiding disposal, and avoiding plastic products. Sustainable and healthy diet education must be implemented to ensure the adoption of all SHDBs.

Background: Appreciating food is an important concept in mindful eating, mentioned by advocates of an expanded model of mindful eating in 2016. With the exception of Japan, this concept is not common in many countries. Objective: We aimed to describe the role that appreciation for food has in the health of children from two perspectives: 1) association between children’s appreciation for food and their backgrounds, such as home and school educational experiences related to food, and 2) association between their appreciation for food and outcomes, such as attitude toward food, eating behaviors, and health status. Design: Cross-sectional. Methods: Data were obtained from self-administered anonymous questionnaires sent to 2070 elementary school students in Tokyo, Japan, during October and December 2006. They contained several question items pertaining to the characteristics of participants: home and school educational experiences related to food, attitudes towards food (including level of appreciation for food), eating behaviors, and health status. T-test, Pearson’s correlation coefficient, and simple and multiple linear regression analyses were used to compare the total score of appreciation for food with other factors. Results: Surveys were completed by 1994 children (response rate: 96.3%) and significant correlations were indicated by gender, educational experiences at home and school, attitudes toward healthy food, recommended food preferences, breakfast consumption, and body mass index. Conclusions: We concluded that appreciation for food plays an important role in children’s health.

Despite a clinical need, only a few studies have provided information concerning visual estimation training for raters to improve the validity of their evaluations. This study aims to describe the differences in the characteristics of raters who evaluated patients' dietary intake in hospitals using the visual estimation method based on their training experiences.We collected data from three hospitals in Tokyo from August to September 2016. The participants were 199 nursing staff members, and they completed a self-administered questionnaire on demographic data; working career; training in the visual estimation method; knowledge, attitude, and practice associated with nutritional care; and self-evaluation of method validity of and skills of visual estimation. We classified participants into two groups, experienced and inexperienced, based on whether they had received training. Square test, Mann-Whitney U test, and univariable and multivariable logistic regression analysis were used to describe the differences between these two groups in terms of their characteristics; knowledge, attitude, and practice associated with nutritional care; and self-evaluation of method validity and tips used in the visual estimation method.Of the 158 staff members (79.4%) (118 nurses and 40 nursing assistants) who agreed to participate in the analysis, thirty-three participants (20.9%) were trained in the visual estimation method. Participants who had received training had better knowledge (2.70 ± 0.81, score range was 1-5) than those who had not received any training (2.34 ± 0.74, p = 0.03). Score of self-evaluation of method validity of the visual estimation method was higher in the experienced group (3.78 ± 0.61, score range was 1-5) than the inexperienced group (3.40 ± 0.66, p 0.01). Mean total scores of using tips in the visual estimation method in the experienced and inexperienced groups were 19.6 ± 1.76 and 17.9 ± 2.28, respectively (score range was 6-24), differing significantly between the two groups (p 0.01). Multivariable logistic regression revealed that participants who had been trained had adequate knowledge (OR: 2.78, 95% CI: 1.05-7.35) and frequently used tips in visual estimation (OR: 1.85, 95% CI: 1.26-2.73).Trained participants had more required knowledge and they used visual estimation tips more frequently than participants who had not been trained in the visual estimation method. This study provides new evidence for the importance of training clinical staff members to use the visual estimation method appropriately and makes suggestions to improve the validity of the visual estimation method.

This study aimed to investigate the correlation between mindful eating and nutritional intake, food consumption, and healthful and unhealthful plant-based dietary patterns in young Japanese women.The sample comprised 215 female undergraduates who responded to a two-questionnaire anonymous survey conducted in Tokyo, Japan in 2018 and 2019 from November to December.

Having a late chronotype, that is, the tendency to go to sleep and wake up at later hours, influences an individual's physical and mental health. Despite a few studies noting the association of chronotype with healthy dietary patterns, this relationship remains unclear.This study aimed to describe the association of chronotype with healthful and unhealthful plant-based diet quality in female Japanese undergraduate students.Cross-sectional.A total of 218 female university students in Tokyo, Japan.Healthful and unhealthful plant-based dietary index-Japanese version (hPDI-J and uPDI-J), calculated using the validated brief-type self-administered diet history questionnaire.A five-model stepwise multiple linear regression analysis was conducted. Independent variables were hPDI-J and uPDI-J scores, and dependent variables were various lifestyle habits related to the circadian rhythm and demographic characteristics.Mean (standard deviation) sleep duration, midpoint of sleep, sleep latency time, and social jetlag were 411 (60) min, 03:56 (00:57), 21 (27) min, and 50 (39) min, respectively. Chronotype and several variables, such as residential status, energy and alcohol intake, and nutritional knowledge, were associated with healthful and unhealthful plant-based diet quality. Individuals who had higher hPDI-J scores were more likely to have an earlier chronotype (β = -0.168, P = 0.019) and better nutritional knowledge (β = 0.164, P = 0.022) than those with lower hPDI-J scores. Individuals were more likely to have higher uPDI-J scores if they were living alone (β = -0.301, P 0.001), had a later chronotype (β = 0.181, P = 0.001), higher frequency of snacking (β = 0.164, P = 0.019), lower total energy (β = -0.445, P 0.001), and worse nutritional knowledge (β = -0.172, P = 0.001).This study provided new evidence as to the relationship between sleep and dietary habits, the interaction of which may affect women's health.

PurposeTo develop and validate the Expanded Mindful Eating Scale (EMES), an expanded mindful eating model created for the promotion of health and sustainability.Design/methodology/approachA cross-sectional study using self-administered questionnaire surveys on Ochanomizu Health Study (OHS) was conducted. The survey was provided to 1,388 female university students in Tokyo, Japan. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and a partial correlation analysis were used to confirm construct and criterion validity. Internal consistency of the EMES was confirmed to calculate Cronbach's alpha.FindingsThe response rate was 38.7 % (n = 537). Mean BMI was 20.21 ± 2.12, and 18.8% of them were classified as “lean” (BMI r = −0.138, −0.315, −0.339, −0.281 and 0.149, p Practical implicationsThe authors suggest the possibility that practitioners and researchers of mindful eating that includes this new concept can use authors’ novel scale as an effective measurement tool.Originality/valueThe EMES, which can multidimensionally measure the concept of the expanded model of mindful eating was first developed in this study.

BackgroundPostoperative serum concentration of C-reactive protein (CRP) is one of the objective quantitative indices integrating the effects of preoperative and intraoperative variables. Higher levels of CRP after gastrointestinal surgery are associated with major postoperative complications. To develop a model for predicting CRP levels on postoperative day (POD) 1 in surgical patients both with and without serious conditions and comorbidities, we modified the previous formula for prediction of CRP levels on POD1, and assessed the accuracy of our modified predictive formula for CRP levels.Material and methodsConsecutive patients of all ages undergoing gastrointestinal surgery under general anesthesia were enrolled in this single-institution prospective cohort study. We developed a modified predictive formula in a calculation cohort. Next, associations between measured CRP levels on POD1, predicted CRP levels on POD1 using the previous and modified models, and major complications after surgery were examined in a validation cohort.ResultsWe obtained the following model in the calculation cohort (n = 222): Modified model for predicting CRP levels on POD1 (mg•dL-1) = -10.13 + 0.0025 Duration of surgery (min) + 15.9 Mean Nociceptive Response (NR) + 0.66 Preoperative CRP level (mg•dL-1). In the validation cohort (n = 440), there was a significant association between measured and predicted CRP levels on POD1 (P < 0.001) No significant difference between the measured and predicted CRP levels using the modified model was observed (P = 0.847). There were also significant associations between the predicted CRP levels and major complications after surgery.ConclusionCRP levels predicted using duration of surgery, mean NR, and preoperative CRP levels are likely identical to measured CRP levels on POD1, being associated with major complications after gastrointestinal surgery.

Background Since a high neuraxial block is one of the serious complications in obstetric anesthesia, simulation training is required for the education of rapid diagnosis and treatment of this complication. Objectives This study aimed to evaluate the effects of a simulation study of the high neuraxial block during epidural analgesia for labor pain on pre- and post-simulation tests in junior clinical trainees, who had graduated a medical school within one or two years and being under a two-month program for anesthesia during the Japanese Postgraduate Medical Education. Methods Twenty-two junior clinical trainees participated in this study from September 2016 to May 2017. Before the simulation training, the participants answered a pretest, providing written responses on "how to approach and treat the rapid spread of anesthesia (high neuraxial block) in painless epidural delivery" in a bullet-point form. The number of correct answers to 12 items was counted for each participant. These items were as follows: mask ventilation, preparation for tracheal intubation, oxygenation, supraglottic airway placement, checking the breathing, checking oxygen saturation using pulse oximetry, checking blood pressure, ephedrine injection, checking epidural tube, assessing the level of sensory block, assessing the level of consciousness, and left uterine displacement. After performing our original training, all participants were debriefed and written responses were obtained to a posttest containing the same content as the pretest. Results The percentage of correct answers significantly increased from 8.3 to 16.7% (P = 0.041) after training. The response rates for "mask ventilation" and "check epidural tube" significantly increased from 13.6 to 54.5% (P = 0.004) and from 4.5 to 27.3% (P = 0.039), respectively, after training. Conclusions Simulation training is likely an effective method for junior clinical trainees on studying diagnosis and treatment of high neuraxial block during epidural analgesia in parturient patients.

Background Saying the words “Itadakimasu” and “Gochisosama” is a common Japanese ritual at the beginning and end of a meal. Many Japanese parents and educators communicate to children to express appreciation for food on a daily basis through these words, and they habitually connect these rituals to further education to avoid food waste to children. Objective This study aimed to examine whether appreciation for food mediates the association of meal-related rituals learned in childhood with the avoidance of food waste behavior among Japanese adults. Study Design, Setting, Participants Four hundred Japanese adults participated in the web-based cross-sectional questionnaire survey. Measurable Outcome/Analysis The following information was included in the questionnaire: participants’ background (age, sex, BMI, household size, subjective social status, and dietary change from a year ago), present avoiding food waste behaviors (measured by a sub-scale of validated “sustainable and healthy eating behaviors” questionnaire; 3 items), present appreciation for food (measured by a sub-scale of the Mindful Eating Inventory; 3 items), rituals before and after the meal in childhood (1 item), and advice from parents or educators to refrain from leaving food in childhood (1 item). Mediation analyses with percentile-corrected bootstrap confidence intervals were conducted to calculate the indirect effects adjusted for participants’ background. Results The participants’ mean (SD) age and BMI were 40.0 (11.6) years and 21.9 (3.9) kg/m2, respectively (female = 50.0%). The mean (SD) score of avoiding food waste was 16.0 (4.08; range: 7–21). Appreciation for food mediated the association between meal-related rituals before and after the meal (indirect effects fully adjusted models: B = 0.085, 95% CI = 0.009–0.184) and advice by parents or educators to refrain from leaving food (B = 0.101, 95% CI = 0.016–0.221) and avoiding food waste behavior. Conclusion Learning experiences from childhood seem to have an influence on present food waste behavior and are mediated by appreciation for food.

PurposeVisual estimation, an easy-to-perform technique, is commonly used in hospitals to assess dietary intake in patients. The authors performed a qualitative study where the authors interviewed nurses and dietitians about their perceptions of barriers to accurately measuring patients’ dietary intake in hospitals using the visual estimation method. The paper aims to discuss these issues.Design/methodology/approachTen dietitians and ten clinical nurses responded to 30-minute individual interviews in Tokyo, Japan, in September 2014. Each interview was conducted using a common protocol of open-ended questions focusing on the challenges of the visual estimation method and barriers to accurately measuring patients’ dietary intake as part of their routine work. The tape-recorded interviews were transcribed and analyzed based on grounded theory.FindingsFive main categories emerged: hospitals, meals, colleagues, raters, and patients. Various individual barriers such as skill, attitude, knowledge, and others that had not been considered in previous studies also emerged. External barriers that were out of the raters’ control, such as shortage of time, human resources, financial ability, and others, emerged from the “hospitals” category.Research limitations/implicationsResearch participants were all females and many of them had less than ten years of experience.Practical implicationsIn addition to standardizing the visual estimation process, medical staff need to overcome various other internal and external barriers to accurate measurements.Originality/valueThis is the first study to articulate some important barriers that influence reliability and validity when measuring patients’ dietary intake by visual estimation methods in typical clinical settings.

The aim of this study was to examine differences in the validity of a visual estimation method for determining patients' meal intake between various meal types and supplied food items in hospitals and to find factors influencing the validity of a visual estimation method.There are two procedures by which we obtained the information on dietary intake of the patients in these hospitals. These are both by visual assessment from the meal trays at the time of their clearing, by the attending nursing staff and by weighing conducted by researchers. The following criteria are set for the target trays: A) standard or therapeutic meals, which are monitored by a doctor, for energy and/or protein and/or sodium; B) regular, bite-sized, minced and pureed meal texture, and C) half-portion meals. Visual assessment results were tested for their validity by comparing with the corresponding results of weighing. Differences between these two methods indicated the estimated and absolute values of nutrient intake.A total of 255 (76.1%) trays were included in the analysis out of the 335 possible trays and the results indicated that the energy consumption estimates by visual or weighing procedures are not significantly different (412 ± 173 kcal, p = 0.15). However, the mean protein consumption was significantly different (16.3 ± 6.7 g/tray, p 0.01) between the two procedures. Compared with standard meals (38 ± 45 kcal, 1.9 ± 2.5 g/tray), raters significantly misestimated the energy and protein intake of half-portion meals (78 ± 65 kcal, 2.8 ± 2.2 g/tray, p = 0.01) but accurately estimated the protein intake of protein controlled meals (0.5 ± 0.6 g/tray, p = 0.03). Trays adding supplied food items were significantly misestimated for energy intake (66 ± 58 kcal/tray) compared to trays with no additions (32 ± 39 kcal/tray, p 0.01). Moreover, the results of multivariable analysis demonstrated that supplied food items were significantly associated with increased odds of a difference between the two methods (OR: 3.84; 95% confidence interval [CI]: 1.07-13.85).There were high correlations between the visual estimation method and the weighing method measuring patients' dietary intake for various meal types and textures, except for meals with added supplied food items. Nursing staff need to be attentive to supplied food items.

Nursing staff have an important role in patients’ nutritional care. The aim of this study was to demonstrate how the practice of sharing a patient’s nutritional status with colleagues was affected by the nursing staff’s attitude, knowledge and their priority to provide nutritional care. The participants were 492 nursing staff. We obtained participants’ demographic data, the practice of sharing patients’ nutritional information and information about participants’ knowledge, attitude and priority of providing nutritional care by the questionnaire. We performed partial correlation analyses and linear regression analyses to describe the relationship between the total scores of the practice of sharing patients’ nutritional information based on their knowledge, attitude and priority to provide nutritional care. Among the 492 participants, 396 nursing staff (80.5%) completed the questionnaire and were included in analyses. Mean±s.d. of total score of the 396 participants was 8.4±3.1. Nursing staff shared information when they had a high nutritional knowledge (r=0.36, P

Background In East Asian countries, which have a high prevalence of underweight individuals, there is little information about the association between dietary factors and abnormal glucose tolerance during pregnancy. We examined the association between carbohydrate intake and moderately abnormal glucose tolerance in Japanese pregnant women. Methods We conducted a prospective study on 325 Japanese pregnant women without a diagnosis of diabetes mellitus prior to pregnancy. Dietary carbohydrate intake (% of total energy intake) was assessed using a 3-day dietary record during weeks 8-15 of pregnancy. Glucose tolerance was assessed by the 50 g glucose challenge test (GCT) during weeks 24-28 of pregnancy. A positive GCT result was defined by a 1-hour plasma concentration ≥ 7.8 mmol/L. Odds ratios of a positive GCT were calculated for the top and middle tertile categories of carbohydrate intake using the bottom category as reference. Results Mean (standard deviation) body mass index at the first prenatal visit was 19.7 (1.9) kg/m2 , and 95 women were underweight. Seventy-four women had positive GCT results. Carbohydrate intake was negatively associated with a positive GCT result after adjusting for age, parity, body mass index at first prenatal visit, family history of diabetes mellitus, rate of gestational weight gain, energy intake, and dietary fiber intake (odds ratio for top category: 0.46 [95% CI, 0.23-0.93]). Conclusions These findings suggest that high carbohydrate intake was negatively associated with moderately abnormal glucose tolerance in a population with a high prevalence of underweight individuals.

The accuracy of the visual estimation method is unknown, even though it is commonly used in hospitals to measure the dietary intake of patients. We aimed to compare the difference in the validity of visual estimation according to the raters' job categories and tray divisions, and to demonstrate associations between meal characteristics and validity of visual estimation in a usual clinical setting in a community hospital.We collected patients' dietary intake data in usual clinical settings for each tray in 3 ways: visual estimation by nursing assistants, visual estimation by dietitians, and weighing by researchers (reference method). Dietitians estimated the dietary intake using 2 divisions, namely, whole tray and food items. Then we compared the weights and visual estimation data to evaluate the validity of the visual estimation method.Mean nutrient consumption of target trays was significantly different when using the visual estimation of target trays than when using the weighed method (visual estimation by nursing assistants [589 ± 168 kcal, 24.3 ± 7.0 g/tray, p 0.01], dietitians' whole trays [561 ± 171 kcal, 23.0 ± 6.9 g/tray, p 0.05], food items [562 ± 171 kcal/tray, p 0.05], and dietitians' food items [23.4 ± 7.3 g/tray, p = 0.63]). Spearman's correlations for both methods were very high for energy (ρ = 0.91-0.98, p 0.01) and protein intakes (ρ = 0.88-0.96, p 0.01), respectively. The limits of agreement in the Bland-Altman plot for both dietary intake categories were -121 kcal to 147 kcal/tray and -6.4 g to 7.0 g/tray (nursing assistants, whole division), -122 kcal-106 kcal/tray and -6.7 g to 5.5 g/tray (dietitians, whole divisions), and -82 kcal to 66 kcal/tray and -4.3 g to 3.9 g/tray (dietitians, food items divisions). High intake rate of grains was significantly associated with decreased odds of a difference between two methods based on the nursing assistant's whole tray evaluation (odds ratio [OR]: 0.85; 95% confidence interval [CI]: 0.76-0.94) and the dietitians' whole tray (OR: 0.80; 95% CI: 0.72-0.89) and food items evaluations (OR: 0.64; 95% CI: 0.56-0.73), respectively. In addition, minced meals were also associated with a difference between two methods, for the nursing assistants' whole tray (OR: 3.53; 95% CI: 1.66-7.51) and dietitians' food items (OR: 2.92; 95% CI: 1.37-6.22).Visual estimation by nursing assistants and dietitians correlated highly with the weighing method although the limits of agreement were wide. Nursing assistants and dietitians should pay attention to low consumption and modified texture meals when evaluating dietary intake using the visual estimation method.

Rationale, aims and objectives: To determine more effective intervention, this qualitative study explores the specific behaviors of adult patients undergoing hemodialysis with regard to dietary and fluid restrictions. Additionally, to understand their characteristics, identified behaviors were categorized as being either intentional or unintentional.Methods: This study employed a descriptive exploratory design comprising individual semi-structured interviews. It was conducted from July to September 2014 in one private dialysis facility treating 73 outpatients in Tokyo, Japan. Forty-three patients receiving hemodialysis treatment consented to participate. Behaviors identified in the interviews were categorized by considering “the motivation behind them (intentional/unintentional)” and their “adequacy (if the behavior seems to lead adherence or not).”Results: This study identified 32 categories of “intentional behaviors” and 14 categories of “unintentional behaviors”. Intentional behaviors included general behaviors of “making adjustments in diet” and non-adherence behaviors of “taking halfway measures” and “abandonment”. Unintentional behaviors comprised general behaviors practiced after the initiation of HD therapy, in addition to non-adherence behaviors due to “habituation” and “dietary environments”.Conclusions: A total of 46 categories of specific behaviors regarding dietary and fluid restrictions in patients receiving HD were identified. Categories were then divided into two different types: intentional and unintentional. Though certain characteristics were similar to other adherence behaviors such as those toward medication, the current study also proposes some unique aspects of dietary behaviors with respect to diversity and habitual strength. Understanding the characteristics of different types of non-adherence behaviors, such as whether they are intentional or unintentional, could be a potentially important contribution to interventions.
