Online citizen sciences reveal natural enemies and new occurrence data of Meteorusstellatus Fujie, Shimizu & Maeto, 2021 (Hymenoptera, Braconidae, Euphorinae).

Background: Citizen science is a research approach that involves collaboration between professional scientists and non-professional volunteers. The utilisation of recent online citizen-science platforms (e.g. social networking services) has greatly revolutionised the accessibility of biodiversity data by providing opportunities for connecting professional and citizen scientists worldwide. Meteorusstellatus Fujie, Shimizu & Maeto, 2021 (Hymenoptera, Braconidae, Euphorinae) has been recorded from the Oriental Islands of Japan and known to be a gregarious endoparasitoid of two macro-sized sphingid moths of Macroglossum, Ma.passalus (Drury) and Ma.pyrrhosticta Butler. It constructs characteristic star-shaped communal cocoons, suspended by a long cable. Although M.stellatus has been reported only from the Oriental Islands of Japan, the authors recognise its occurrence and ecological data from Taiwan and the Palaearctic Island of Japan through posts on online citizen-science groups about Taiwanese Insects on Facebook and an article on a Japanese citizen-scientist's website. New information: Through collaboration between professional and citizen scientists via social media (Facebook groups) and websites, the following new biodiversity and ecological data associated with M.stellatus are provided: Meteorusstellatus is recorded for the first time from Taiwan and the Palaearctic Region (Yakushima Is., Japan).Cechetraminor (Butler, 1875), Hippotioncelerio (Linnaeus, 1758) and Macroglossumsitiene (Walker, 1856) (Lepidoptera, Sphingidae) are recorded for the first time as hosts of M.stellatus and two of which (C.minor and H.celerio) represent the first genus-level host records for M.stellatus.Mesochorus sp. (Hymenoptera, Ichneumonidae), indeterminate species of Pteromalidae and Trichogrammatidae (Hymenoptera), are recognised as hyperparasitoid wasps of M.stellatus.Parapolybiavaria (Fabricius, 1787) (Hymenoptera, Vespidae) is reported as a predator of pendulous communal cocoons of M.stellatus. The nature of suspended large-sized communal cocoons of M.stellatus and the importance and limitations of digital occurrence data and online citizen science are briefly discussed.

End-of-Life-Care Quality in ICUs Is Associated With Family Surrogates' Severe Anxiety and Depressive Symptoms During Their First 6 Months of Bereavement.

OBJECTIVES: Evidence linking end-of-life-care quality in ICUs to bereaved family members' psychologic distress remains limited by methodological insufficiencies of the few studies on this topic. To examine comprehensively the associations of family surrogates' severe anxiety and depressive symptoms with end-of-life-care quality in ICUs over their first 6 months of bereavement. DESIGN: Prospective, longitudinal, observational study. SETTING/PARTICIPANTS: Family surrogates (n = 278) were consecutively recruited from seven medical ICUs at two academically affiliated medical centers in Taiwan. MEASUREMENTS AND STATISTICAL ANALYSIS: Family surrogates' anxiety and depressive symptoms were assessed 1, 3, and 6 months postloss using the Hospital Anxiety and Depression Scale. Family satisfaction with end-of-life care in ICUs was assessed 1-month postloss by the Family Satisfaction in the ICU questionnaire. Patients' end-of-life care was documented over the patient's ICU stay. Associations of severe anxiety and depressive symptoms (scores ≥ 8 for each subscale) with end-of-life-care quality in ICUs (documented by patient care received and family satisfaction with end-of-life care in ICUs) were examined by multivariate logistic regression models with generalized estimating equation. MAIN RESULTS: Prevalence of severe anxiety and depressive symptoms decreased significantly over time. Surrogates' lower likelihood of severe anxiety or depressive symptoms 3-6 month postloss was associated with death without cardiopulmonary resuscitation, withdrawing life-sustaining treatments, and higher family satisfaction with end-of-life care in ICUs. Bereaved surrogates' higher likelihood of these symptoms was associated with physician-surrogate prognostic communication and conducting family meetings before patients died. CONCLUSIONS: End-of-life-care quality in ICUs is associated with bereaved surrogates' psychologic well-being. Enhancing end-of-life-care quality in ICUs by improving the process of end-of-life care, for example, promoting death without cardiopulmonary resuscitation, withdrawing life-sustaining treatments, and increasing family satisfaction with end-of-life care, can lighten bereaved family surrogates' severe anxiety symptoms and severe depressive symptoms.

Quality Assessments of End-of-Life Care by Medical Record Review for Patients Dying in Intensive Care Units in Taiwan.

CONTEXT/OBJECTIVE: Essential indicators of high-quality end-of-life care in intensive care units (ICUs) have been established but examined inconsistently and predominantly with small samples, mostly from Western countries. Our study goal was to comprehensively measure end-of-life-care quality delivered in ICUs using chart-derived process-based quality measures for a large cohort of critically ill Taiwanese patients. METHODS: For this observational study, patients with APACHE II score ≥20 or goal of palliative care and with ICU stay exceeding three days (N = 326) were consecutively recruited and followed until death. RESULTS: Documentation of process-based indicators for Taiwanese patients dying in ICUs was variable (8.9%-96.3%), but high for physician communication of the patient's poor prognosis to his/her family members (93.0%), providing specialty palliative-care consultations (73.3%), a do-not-resuscitate order in place at death (96.3%), death without cardiopulmonary resuscitation (93.5%), and family presence at patient death (76.1%). Documentation was infrequent for social-worker involvement (8.9%) and interdisciplinary family meetings to discuss goals of care (22.4%). Patients predominantly (79.8%) continued life-sustaining treatments (LSTs) until death and died with full life support, with 88.3% and 58.9% of patients dying with mechanical ventilation support and vasopressors, respectively. CONCLUSIONS: Taiwanese patients dying in ICUs heavily used LSTs until death despite high prevalences of documented prognostic communication, providing specialty palliative-care consultations, having a do-not-resuscitate order in place, and death without cardiopulmonary resuscitation. Family meetings should be actively promoted to facilitate appropriate end-of-life-care decisions to avoid unnecessary suffering from potentially inappropriate LSTs during the last days of life.

Structural color mechanism in the Papilio blumei butterfly.

The structural color found in biological systems has complicated nanostructure. It is very important to determine its color mechanism. In this study, the 2D photonic crystal structures of the Papilio blumei butterfly were constructed, and the corresponding reflectance spectra were simulated by the finite-difference time-domain method. The structural color of the butterfly depends on the incident angle of light, film thickness, film material (film refractive index), and the size of the air hole (effective refractive index). Analysis of simulations can help us understand the hue, brightness, and saturation of structural color on the butterfly wing. As a result, the analysis can help us fabricate expected structural color.

Fabrication of a tunable daylight simulator.

Recently, solid state lighting has begun to play an important role in colorimetric instrumentation. LEDs are being evaluated as one of the possible standard light sources for such devices. In this study, an innovative tunable daylight simulator is developed, which mainly consists of only a few LEDs and a specially designed optical thin-film filter with a fixed transmission spectrum. This simulator is able to simulate daylight spectra with correlated color temperatures ranging from 4000 to 10,000 K with very good color rendition indices (CRI≧97). We have achieved the color difference 0.01, which is better than 0.015, a maximum tolerance as defined by the International Commission on Illumination of the color differences in 1976 u'v' color space between standard daylight and a simulator.
