The results suggest the need to carry out a multidimensional assessment of spiritual functioning of persons beginning alcohol addiction therapy to provide treatment that is adjusted to patients' spiritual potential and deficits.For equivalence trials with survival outcomes, a popular testing approach is the elegant test for equivalence of two survival functions suggested by Wellek (Biometrics 49 877-881, 1993). This test evaluates whether or not the difference between the true survival curves is practically irrelevant by specifying an equivalence margin on the hazard ratio under the proportional hazards assumption. However, this approach is based on extrapolating the behavior of the survival curves to the whole time axis, whereas in practice survival times are only observed until the end of follow-up. We propose a modification of Welleks test that only addresses equivalence until end of follow-up and derive the large sample properties of this test. Another issue is the proportional hazards assumption which may not be realistic. If this assumption is violated, one may severely misjudge the actual treatment effect with a hazard ratio quantification and wrongly declare equivalence. We suggest a non-parametric test for assessing survival equivalence within the follow-up period. We derive the large sample properties of this test and provide an approximation to the limiting distribution under some mild assumptions on the functional form of the difference between the two survival curves. Both suggestions are investigated by simulation and applied to a clinical trial on survival of gastric cancer patients.Decades ago, in his foundational essay on the early days of the AIDS crisis, medical historian Charles Rosenberg wrote, "epidemics start at a moment in time, proceed on a stage limited in space and duration, following a plot line of increasing revelatory tension, move to a crisis of individual and collective character, then drift toward closure." In the course of epidemics, societies grappled with sudden and unexpected mortality and also returned to fundamental questions about core social values. "Epidemics," Rosenberg wrote, "have always provided occasion for retrospective moral judgment" (Rosenberg 1989, pp. VH298 order 2, 9). Following Rosenberg's observations, this essay places COVID-19 in the context of epidemic history to examine common issues faced during health crises-moral, political, social, and individual. Each disease crisis unfolds in its own time and place. Yet, despite specific contexts, we can see patterns and recurring concerns in the history of pandemics (1) pandemics and disease crises in the past, along with public health responses to them, have had implications for civil liberties and government authority; (2) disease crises have acted as a sort of stress test on society, revealing, amplifying or widening existing social fissures and health disparities; (3) pandemics have forced people to cope with uncertain knowledge about the origin and nature of disease, the best sources of therapies, and what the future will hold after the crisis. While historians are not prognosticators, understanding past experience offers new perspectives for the present. The essay concludes by identifying aspects of history relevant to the road ahead.NADPH oxidase (NOX) is a main producers of reactive oxygen species (ROS) that may contribute to the early pathogenesis of diabetic retinopathy (DR). ROS has harmful effects on endogenous neuro-survival factors brain-derived neurotrophic factor (BDNF) and sirtuin 1 (SIRT1) are necessary for the growth and survival of the retina. The role of NOX isoforms NOX4 in triggering ROS in DR is not clear. Here we determine the protective effects of a plant-derived NOX inhibitor apocynin (APO) on NOX4-induced ROS production which may contribute to the depletion of survival factors BDNF/SIRT1 or cell death in the diabetic retinas. Human retinal Müller glial cells (MGCs) were treated with hypoxia mimet
