Suicide exposure is associated with an increased risk for suicide. There is limited research on the mechanisms that increase this risk. This study aims to (1) compare suicide exposure and associated variables in veteran, active duty, and civilian participants, (2) examine the extent to which fearlessness about death and suicide risk factors differ as a function of group membership and suicide exposure, and (3) determine the degree to which relationship to the decedent, perceived closeness, and reported impact of the death are associated with fearlessness about death and suicide-related outcomes. 1,533 participants were included, of whom 48% of active duty service members, 65% of veterans, and 58% of civilians reported knowing someone who died by suicide. A series of regressions were conducted. There were group differences by military service on the suicide exposure variables. Furthermore, there were significant main effects for military service group and suicide exposure on the outcome variables. In general, civilians reported greater suicide risk and active duty service members reported greater fearlessness about death. Fearlessness about death mediated the associations between perceived closeness and a history of suicide attempts. The loss of a military colleague to suicide was found to be unique and distinguishable from other important relationships. Results suggest the need to consider suicide exposure and closeness as salient variables associated with fearlessness about death and suicide risk factors. Inquiring about suicide exposure, closeness to the decedent, fearlessness about death, and beyond familial losses to suicide may indicate important avenues of intervention.Purpose The larynx is a uniquely situated organ, juxtaposed between the gastrointestinal and respiratory tracts, and endures considerable immunological challenges while providing reflexogenic responses via putative mucosal mechanoreceptor afferents. Laryngeal afferents mediate precise monitoring of sensory events by relay to the internal branch of the superior laryngeal nerve (iSLN). Exposure to a variety of stimuli (e.g., mechanical, chemical, thermal) at the mucosa-airway interface has likely evolved a diverse array of specialized sensory afferents for rapid laryngeal control. [https://www.selleckchem.com/products/rg108.html Selleck RG108] Accordingly, mucosal mechanoreceptors in demarcated laryngeal territories have been hypothesized as primary sources of sensory input. The purpose of this article is to provide a tutorial on current evidence for laryngeal afferent receptors in mucosa, the role of mechano-gated ion channels within airway epithelia and mechanisms for mechanoreceptors implicated in laryngeal health and disease. Method An overview was conducted on the distribution and identity of iSLN-mediated afferent receptors in the larynx, with specific focus on mechanoreceptors and their functional roles in airway mucosa. Results/Conclusions Laryngeal somatosensation at the cell and molecular level is still largely unexplored. This tutorial consolidates various animal and human researches, with translational emphasis provided for the importance of mucosal mechanoreceptors to normal and abnormal laryngeal function. Information presented in this tutorial has relevance to both clinical and research arenas. Improved understanding of iSLN innervation and corresponding mechanotransduction events will help shed light upon a variety of pathological reflex responses, including persistent cough, dysphonia, and laryngospasm.Purpose The purpose of this study was to evaluate the effect of infant formula type and preparation (i.e., ready-to-feed vs. powder) on International Dysphagia Diet Standardisation Initiative (IDDSI) thickness level and milk flow rates from bottle teats/nipples. Method The ready-to-feed and powder formulations of the following products were tested for IDDSI thickness level, using IDDSI guidelines, and for milk flow rate, using established flow testing methods Similac Advance, Similac For Spit-Up, Enfamil Infant, and Enfamil A.R. Analysis of variance was used to compare flow rates among formula types/preparations. Results Enfamil A.R. ready-to-feed was classified as IDDSI "slightly thick." All other formula types/preparations were found to be IDDSI "thin" liquids. The standard infant formulas (Similac Advance and Enfamil Infant) had comparable flow rates to each other, regardless of preparation (ready-to-feed and powder). The gastroesophageal reflux-specific formulas (Similac For Spit-Up and Enfamil A.R.) had slower flow rates than the standard formulas; within this category, there were significant differences in flow rates between ready-to-feed and powder. Enfamil A.R. powder had the slowest flow rate, but was the most variable. Conclusion For infants with difficulty coordinating sucking, swallowing, and breathing, clinicians and parents should consider the impact that changes to infant formula type and preparation may have on the infant's ability to safely feed.The care for individuals with cystic fibrosis (CF) with at least one F508del mutation will greatly change as a result of the unparalleled clinical benefits observed with the new triple combination CF transmembrane regulator (CFTR) modulator therapy elexacaftor/tezacaftor/ivacaftor (ETI). Incorporating ETI into standard of care creates new motivation and opportunity to consider reductions in overall treatment burden and evaluate whether other chronic medications can now be safely discontinued without loss of clinical benefit. SIMPLIFY is a master protocol poised to test the impact of discontinuing versus continuing two commonly used chronic therapies in people with CF who are at least 12 and older andstable on ETI therapy. The protocol is comprised of two concurrent randomized, controlled trials designed to evaluate the independent short-term effects of discontinuing hypertonic saline or dornase alfa, enabling individuals on both therapies to participate in one or both trials. The primary objective for each trial is to determine whether discontinuing treatment is non-inferior to continuing treatment after establishment of ETI, as measured by the 6-week absolute change in forced expiratory volume in one second (FEV1) % predicted. Developing this study required a balance between ideal study design principles and feasibility. SIMPLIFY will be the largest multicenter, randomized, controlled medication withdrawal study in CF. This study is uniquely positioned to provide timely evidence on whether daily treatment burden can be reduced among individuals on CFTR modulator therapy.
