Multiple risk factors for unplanned readmissions within 1 month of hospital discharge in acute care hospitals in Japan.

AIM: The aim of this study is to analyse the risk factors for unplanned readmissions within 1 month after hospital discharge to develop a seamless support system from discharge to home care. BACKGROUND: With shorter hospital stay lengths, understanding the characteristics of patients with multiple risk factors is important to prevent rehospitalization. DESIGN: This is a single-centre retrospective descriptive study. METHODS: Logistic regression and decision tree analyses were performed using eight items from the records of 3117 patients discharged from a university hospital between April-September 2017 as risk factors. RESULTS: Unplanned readmission risk was significantly associated with emergency hospitalization (odds ratio [OR]: 3.12, 95% confidence interval [CI]: 2.04-4.77), malignancy (OR: 2.16, 95% CI: 1.44-3.24), non-surgical admission (OR: 1.76, 95% CI: 1.07-2.88), hospital stay of ≥ 15 days (OR: 1.66, 95% CI: 1.14-2.43) and decline in activities of daily living owing to hospitalization (OR: 1.68, 95% CI: 1.06-2.64). The highest risk combinations for rehospitalization were as follows: emergency hospitalization and malignancy; emergency admission, non-malignancy and a hospital stay of ≥15 days; and scheduled hospitalization, no surgery and a hospital stay of ≥15 days. CONCLUSIONS: Patients with multiple risks for unplanned readmission should be accurately screened and provided with optimal home care.

[Characteristics of ethical dilemma and behavior in the support process of older adults and their families among nurses at a community general support center in Japan].

Objectives　This study was aimed at clarifying characteristics of ethical dilemmas and behaviors in the support process of older adults and their families among nurses at community general support centers.Methods　A self-administered questionnaire survey was mailed to 449 nurses at community general support centers in Tokyo. Question items enquired their age, employment license, years of experience as a nurse, the presence of ethics-related organizations, number of cases in which nurses faced difficulties in supporting older adults and their families in decision making over the past year, the ethical dilemmas they experienced and their situations, and ethical behavior in the process of supporting older adults and their families.Results　From the 143 responses (response rate: 31.8%), 135 (valid response rate: 30.1%) nurses were analyzed. Overall, 43.0% and 27.4% of the participants were in their 50s and 40s, respectively. Of these, 77.0% and 23.0% were nurses and public health nurses, respectively. In total, 52 (38.5%) respondents had an ethics-related organization. The average number of cases in which the respondents faced difficulties in supporting older adults and their families in decision making over the past year was 8.3 (standard deviation, 12.5). Of these, the average number of cases in which they faced difficulties in making ethical decisions was 4.1 (standard deviation, 6.0). Regarding the perception of ethical dilemmas, 113 (83.7%) answered "often" or "sometimes." Ethical dilemma situations included "the intentions of the user and family were different, and I had trouble deciding what to respect" 95 (84.1%); "the user's intention was different from my judgment as a professional, and I had trouble deciding what to respect" 64 (56.6%); and "the intention of the user and neighbors were different, and I had trouble deciding what to respect" 56 (49.6%). Ethical behaviors included "I observe the management rules in my organization regarding personal information data" 116 (85.9%); "I provide easy-to-understand explanations appropriate to the user's situation" 115 (85.2%); and "I decide on a support policy with several staff members when self-decision making is difficult due to the user's situation" 113 (83.7%).Conclusion　More than 80% of the nurses perceived ethical dilemmas. Characteristics of the situations were that users and their families, users and professionals, and users and their neighbors had different intentions. Further research should be conducted on ethical issues related to community-based integrated care.

Macroglossia in advanced amyotrophic lateral sclerosis.

INTRODUCTION: An enlarged tongue (macroglossia) has been reported in advanced-stage patients with amyotrophic lateral sclerosis (ALS). METHODS: In this study we examined the prevalence of macroglossia and analyzed clinical correlations in 65 ALS patients on tracheostomy-invasive ventilation (TIV). RESULTS: Macroglossia was found in 22 patients (33.8%). Compared with those without macroglossia, patients with macroglossia had a younger age of onset, longer duration of disease and TIV use, lower ALS Functional Rating Scale score, higher body mass index, lower energy intake, more severe communication impairment, and lower oral function. Logistic multivariate analysis showed that body mass index (BMI; P = 0.007) and communication impairment (P = 0.029) were significantly correlated with macroglossia. The duration of TIV use was at the cut-off level of significance (P = 0.05). CONCLUSIONS: Macroglossia may be the result of overfeeding and replacement by fat during long-term TIV use in patients with advanced ALS. Muscle Nerve, 2016 Muscle Nerve 54: 386-390, 2016.

Isolation and characterization of 1-palmitoyl-2-linoleoyl-sn-glycerol as a hormogonium-inducing factor (HIF) from the coralloid roots of Cycas revoluta (Cycadaceae).

Coralloid roots are specialized tissues of cycads (Cycas revoluta) that are involved in symbioses with nitrogen-fixing Nostoc cyanobacteria. We found that a crude methanolic extract of coralloid roots induced differentiation of the filamentous cell aggregates of Nostoc species into motile hormogonia. Hence, the hormogonium-inducing factor (HIF) was chased using bioassay-based isolation, and the active principle was characterized as a mixture of diacylglycerols (DAGs), mainly composed of 1-palmitoyl-2-linoleoyl-sn-glycerol (1), 1-palmitoyl-2-oleoyl-sn-glycerol (2), 1-stearoyl-2-linolenoyl-sn-glycerol (3), and 1-stearoyl-2-linoleoyl-sn-glycerol (4). Enantioselectively synthesised compound 1 showed a clear HIF activity at 1 nmol (0.6 µg) disc-1 for the filamentous cells, whereas synthesised 2-linoleoyl-3-palmitoyl-sn-glycerol (1') and 1-palmitoyl-2-linoleoyl-rac-glycerol (1/1') were less active than 1. Conversely, synthesised 1-linoleoyl-2-palmitoyl-rac-glycerol (8/8') which is an acyl positional isomer of compound 1 was inactive. In addition, neither 1-monoacylglycerols nor phospholipids structurally related to 1 showed HIF-like activities. As DAGs are protein kinase C (PKC) activators, 12-O-tetradecanoylphorbol-13-acetate (12), urushiol C15:3-Δ10,13,16 (13), and a skin irritant anacardic acid C15:1-Δ8 (14) were also examined for HIF-like activities toward the Nostoc cells. Neither 12 nor 13 showed HIF-like activities, whereas 14 showed an HIF-like activity at 1 nmol/disc. These findings appear to indicate that some DAGs act as hormogonium-inducing signal molecules for filamentous Nostoc cyanobacteria.

Statistical estimation of the number of breast cancer patients with disabilities resulting from surgery.

BACKGROUND: The prolongation of the post-operative life of cancer patients brings new medical demands. The purpose of this paper is to estimate the total number of women patients with breast cancer who will have disability resulting from surgical treatment from 2000 to 2020 in Japan. METHODS: The estimation was carried out using four indices: the number of cases of women diagnosed with breast cancer, the proportion of surgical operations, the frequency of disability from surgical treatment, and the crude survival rate of the patient group. The crude survival rates of surgically-treated breast cancer patients were estimated by the Weibull model. The frequencies of iatrogenic disabilities were calculated from several reports of complaints of pain in the chest wall or axilla and lymphedema of the arm, and 95% confidence intervals were calculated by the Monte Carlo simulation. RESULTS AND DISCUSSION: The number of women patients with disability from breast cancer treatment from 2000 to 2020 was estimated to be 42,016 (95% CI: 41,236, 42,796) people in 2000 and 72,514 (95% CI: 71,196, 73,832) people in 2020 for pain in the chest wall or axilla, and 22,486 (95% CI: 22,148, 22,823) people in 2000 and 38,692 (95% CI: 38,094, 39,290) people in 2020 for lymphedema of the arm. Treatment supports required for the disability are medication and social support. Cancer patients with disability after treatment need long-term support in their daily life.
