Protocol for a multicentre, prospective, cohort study to investigate patient satisfaction and quality of life after immediate breast reconstruction in Japan: the SAQLA study.

INTRODUCTION: The aim of breast reconstruction (BR) is to improve patients' health-related quality of life (HRQOL). Therefore, measuring patient-reported outcomes (PROs) would clarify the value and impact of BR on a patient's life and thus would provide evidence-based information to help decision-making. The Satisfaction and Quality of Life After Immediate Breast Reconstruction study aimed to investigate satisfaction and HRQOL in Japanese patients with breast cancer who undergo immediate breast reconstruction (IBR). METHODS AND ANALYSIS: This ongoing prospective, observational multicentre study will assess 406 patients who had unilateral breast cancer and underwent mastectomy and IBR, and were recruited from April 2018 to July 2019. All participants were recruited from seven hospitals: Okayama University Hospital, Iwate Medical University Hospital, The Cancer Institute Hospital of Japanese Foundation for Cancer Research, Showa University Hospital, University of Tsukuba Hospital, Osaka University Hospital and Yokohama City University Medical Center. The patients will be followed up for 36 months postoperatively. The primary endpoint of this study will be the time-dependent changes in BREAST-Q satisfaction with breast subscale scores for 12 months after reconstructive surgery, which will be collected via an electronic PRO system. ETHICS AND DISSEMINATION: This study will be performed in accordance with the Ethical Guidelines for Medical and Health Research Involving Human Subjects published by Japan's Ministry of Education, Science and Technology and the Ministry of Health, Labour and Welfare, the modified Act on the Protection of Personal Information and the Declaration of Helsinki. This study protocol was approved by the institutional ethics committee at the Okayama University Graduate School of Medicine, Dentistry, on 2 February 2018 (1801-039) and all other participating sites. The findings of this trial will be submitted to an international peer-reviewed journal. TRIAL REGISTRATION NUMBER: UMIN000032177.

Association between maternal feeling about pregnancy and child's lifestyle.

The number of children with undesirable lifestyles has recently increased. We tested the hypothesis that maternal feelings about pregnancy might be associated with their attitude towards promoting healthy lifestyles in their children. We used a city database collected from guardians of 204 randomly selected children aged 1 to 3 years in Nihonmatsu City, Fukushima. Maternal feeling about pregnancy was measured using a 10-point scale, and a child lifestyle score was calculated as the sum of desirable lifestyle habits (sleeping, eating, watching TV/videos, and tooth brushing). Associations between maternal feeling and her child's lifestyles were examined with multiple logistic regression analysis. For all lifestyle items, proportion of children with undesirable lifestyle habits was higher in the "unhappy group" (those who scored 1 to 9) than in the "happy group" (those who scored 10). In particular, a child's short sleeping hours (odds ratio [OR]=3.01) and lifestyle score of less than 3 ([OR] =3.60) were significantly associated with unhappy feelings. This was apparent among mothers aged 29 (median age) or younger. Our results indicate an association between a mother's unhappy feelings about pregnancy and her child's undesirable lifestyle, especially among relatively younger mothers. These findings provide public health implications important for early familial intervention to improve children's lifestyles.

Spontaneous gingivitis related to hair penetration in rats.

Maxillary gingivae from male and female Crl:CD(SD) rats at 12, 16, 21, and 34 weeks of age were examined histologically. The incidence of gingivitis was approximately 40%, with no age or sex predilection, and was most frequent between the first and second molar. Lesions were characterized by acute focal neutrophilic infiltration into the gingival mucosa, occasionally with inflammatory exudate. In severe cases, inflammation extended to the periodontal ligament with abscess formation, and adjacent alveolar bone destruction/resorption. The most characteristic finding was the presence of hair shafts associated with the lesion, which was observed in approximately 80% of the rats with gingivitis. These findings suggest that molar gingivitis occurs in rats from an early age and persists thereafter, and that the main cause of gingivitis in rats is hair penetration into the gingiva. It would be prudent to keep these background lesions in mind as potential modifiers in toxicity studies.
