The use of artificial organs is likely to increase in the future, given technological advances, increases in chronic diseases, and limited donor organs. This article examines how artificial organs could affect people's experience and conceptualization of bodies and our understanding of the relation of body to self. I focus on artificial heart devices and argue that these have two conflicting potential influences. First, they may influence people to regard the body as machinelike and separable from the self. Second, they may effect changes to subjective experience that can be understood as changes to the self, confirming the self's embodiment. My primary purpose is to increase our understanding of what might change if it becomes more usual to have a body that is partly nonorganic. But I also argue that the analysis points to potential ethical concerns related to strengthening biomedical conceptions of the body and to the devaluing of bodies and body parts.<br />Tonsillectomy is an effective treatment for periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome, but the role of adenoidectomy, as well as later tonsillar regrowth, is unclear. To find out if the volume of lymphoid tissue is pivotal to the efficacy, we analyzed the association between the relapse of the symptoms of PFAPA syndrome and regrowth of tonsillar tissue after tonsillectomy or adenotonsillectomy.<br />Prospective cohort study of operated PFAPA pateints.<br />We invited all patients that had undergone tonsillectomy or adenotonsillectomy due to PFAPA syndrome at the Oulu University Hospital, Oulu, Finland, between the years 1990 and 2007, at the age of ≤12 years, to a follow-up visit, after an average period of 9.8 years after their diagnoses. Out of the 132 invited, 94 (71%) participated in the follow-up study.<br />At the follow-up study visit, 5 (5%) of the 94 PFAPA syndrome cases experienced recurrent fevers. The regrowth of palatine tonsillar tissue was seen in four of them (80%) as compared to 19/89 (21%) of symptom-free patients (P=.006). Two of the patients with clear PFAPA relapse at the time of the study visit were reoperated with clear effect on the symptoms. At the time of the study visit, 59/63 (94%) of the patients who had undergone adenotonsillectomy and 30/31 of the patients (97%) who had undergone tonsillectomy earlier were free of fever flares (P=.99).<br />Palatine tonsil regrowth was associated with PFAPA syndrome relapse after tonsillectomy. Reoperation might be a treatment option in these patients.<br />4 Laryngoscope, 131E2149-E2152, 2021.<br />4 Laryngoscope, 131E2149-E2152, 2021.The pressing need for more randomized controlled trials (RCTs) of treatments for childhood mental disorders has been emphasized by researchers and clinicians as well as in recent commentaries in JCPP (e.g. Stringaris, 2014). Despite the significant increase in research on aetiology, course and antecedents of developmental psychopathology more generally, and the numerous important discoveries that have been made in this domain in the last two decades, the translation of these findings into clinical practice has lagged behind (Insel and Gotay, 2014). Currently, based on limitations in the extant literature, treatment decisions by child mental health clinicians are still made largely based on personal anecdotal experience. Consistent with this, wide variation in prescribing practices have been found by region internationally (Steinhausen, 2015). When it comes to psychotherapeutic interventions, these clinical strategies are often driven by the limited availability of empirically supported treatments in any given community. In the case of psychopharmacologic treatments, while some clinical guidelines are now available, much more definitive data are needed to inform indications, optimal dosing and duration of treatment, uses of polypharmacy, as well as more nuanced information about differential developmental effects. Therefore, a significant gap still exists between clinical practice and the empirical database in the treatment of child mental disorders. Further, the available database is also limited by small sample sizes and mixed findings, making it much less straightforward to coherently guide clinical treatment of childhood psychopathology.The occupancy and abundance of species are jointly driven by local factors, such as environmental characteristics and biotic interactions, and regional-scale factors, such as dispersal and climate. Recently, it has been shown that biotic interactions shape species occupancies and abundances beyond local extents. However, for small ectothermic animals, particularly for those occurring in freshwater environments, the importance of biotic interactions remains understudied. [https://www.selleckchem.com/products/leupeptin-hemisulfate.html this website] Species-to-species associations from joint species distribution models (i.e. species associations while controlling for environmental characteristics) are increasingly used to draw hypotheses of which species possibly show biotic interactions. We studied whether species-to-species associations from joint species distribution models show signs of competition using a hypothesis testing framework in stream macroinvertebrate communities at regional extent. We sampled aquatic macroinvertebrates from 105 stream sites in western Finland encompassing e competition (H1-H4) were rejected. Competition does not appear to be a major driving force of stream macroinvertebrate communities at the spatial grain sizes considered. The observed positive associations in occupancy at small grain (stream site) may be attributed to species' similar microhabitat preferences, whereas at large grain (river basin), they may stem from metacommunity dynamics. Our results highlight that species traits were necessary to interpret whether or not species-to-species associations from joint species distribution models resulted from biotic interactions.In a time of rapid habitat destruction threatening the existence of many species, restoration of degraded habitats plays a crucial role in hampering biodiversity decline and recovering ecosystem services. The goal of this study is to advance the understanding of the consequences of habitat restoration on metacommunities, which is of upmost importance for designing successful restoration projects. We approach habitat restoration from a theoretical perspective by analysing spatially explicit metacommunity models which have previously been essential to understanding the effects of habitat loss and fragmentation. We investigate the efficiency of various restoration strategies on metacommunities involving interactions ranging from pairwise competition, predation and mutualism to more complex three-trophic modules. Our novel approach for measuring the restoration efficiency enables direct comparison of the responses of species in different metacommunities. We show that species recovery is affected by the amount of habitat destroyed, and the restoration strategy.
