To achieve 'Sustainable Healthy Diets', it is critical to address the observed gender discrepancy in meal preparation time allocation. Japanese fathers spend significantly less time on food-related housework (foodwork) than mothers. This study aimed to investigate the association between fathers' childhood meal preparation experiences and their current cooking skills in preparing healthy meals for their children, as well as their involvement in foodwork in Japan. An online cross-sectional study was conducted in November 2022 with 500 Japanese fathers living in dual-earner households with children aged 3-6 years. An analysis of covariance (ANCOVA) was used to examine the above-mentioned associations, with fathers' age and education as control variables. This study examined 463 fathers who did not live with their children's grandparents. We evaluated the fathers' cooking skills on a scale and obtained an average score of 6.9, ranging from 3 to 15; foodwork involvement was assessed similarly, resulting in an average score of 4.1, ranging from 0 to 8. ANCOVA results showed that fathers with experience in meal preparation from childhood were more likely to have higher cooking skills scores (adjusted mean (SEM) = 7.8 (0.35)) than fathers with no experience (adjusted mean (SEM) = 6.5 (0.24), adjusted p  < 0.05). They were also more likely to have higher foodwork involvement scores (adjusted mean (SEM) = 4.9 (0.26)) than fathers with no experience (adjusted mean (SEM) = 3.8 (0.18)) or experiences from adulthood (adjusted mean (SEM) = 4.0 (0.28), adjusted p  < 0.05). Therefore, fathers' childhood meal preparation experience may impact their current cooking skills and foodwork involvement. Hence, age-appropriate programs are required that continually encourage children to prepare meals at home., Competing Interests: Declaration of conflicting interestsThe authors have no conflicts of interest to declare.

Female Japanese flounder Paralichthys olivaceus grow more rapidly than the male. The goal of all-female commercial production requires an efficient method of genetic sex identification. We conducted genome-wide association analysis of female and male farmed Japanese flounder (n = 24 per phenotypic sex) and found all regions of chromosome 24 to be significantly associated with phenotypic sex, suggesting it as the sex chromosome. Genetic sex was identified based on single nucleotide polymorphisms (SNP) on chromosome 24 (n = 3568) using multidimensional scaling analysis, and individuals were clearly separated according to sex by the first dimension. The 61 SNPs most highly associated with sex were selected, and an amplicon-based SNP panel was developed. This was used to determine genetic sex of 39 females and 40 males. Eleven phenotypic males were assigned as female with XX genotype, suggesting sex reversal. Genetic sex was also assessed based on the indel of the amh gene promoter, which is the major candidate sex gene of Japanese flounder. We found four SNPs perfectly associated with genotypic sex in the sex-associated SNP panel, one of which was located in exon 2 of the amh gene. Along with the indel of the amh gene promoter, the sex-associated SNP panel will be of value in identifying genetic sex of farmed Japanese flounder. Molecular sexing will facilitate all-female production by breeding sex-reversed males., (© 2023.

Background: Although the multidisciplinary-collaborated team approach in cancer treatment has recently become popular, prospectively evaluated evidence is limited. We started a multidisciplinary-collaborated cancer support team (MCST) to facilitate cooperation across multidisciplinary medical staff in our hospital and established clinical evidence of supportive care. This study aimed to prospectively evaluate the clinical activity and effect of MCST in patients with gastrointestinal cancer receiving chemotherapy., Methods: This is a single-center, single-arm, observational study. Patients with gastrointestinal cancer scheduled to receive chemotherapy are enrolled and supported by the MCST. The primary endpoints are the number of interventions by medical staff and the number of patients who showed improvement in side effects. The secondary endpoints are the severity of side effects, medical expenses, number of consultations, the acceptance rate of prescription recommendations, adjuvant chemotherapy completion rates, dose intensity, and time required for co-medical intervention. In addition, medical staff and attending physicians evaluate all adverse events., Discussion: This study is expected to contribute to establishing new cancer-supportive care teams for patients with gastrointestinal cancer receiving chemotherapy and those with cancer receiving chemotherapy., Trial Registration: This trial was registered in the Japan Registry of Clinical Trials (jRCT) as jRCT1030220495.

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., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Yui Kawasaki reports financial support was provided by the Asahi group foundation., (Copyright © 2022 Elsevier Ltd.
