Targeting Burdensomeness among Clinic Referred Youth: Development of a CBT Module

Research has established perceived burdensomeness toward others as a correlate and risk factor for suicide ideation in youth. Existing CBT protocols for internalizing disorders target thoughts and behaviors related to anxiety and/or depression, but do not explicitly target other identified risk factors for suicide ideation, including perceived burdensomeness toward others. The aims of the current study were to (1) develop a novel, brief selective prevention module (the “Give program”) targeting perceived burdensomeness toward others that can be embedded within existing CBT protocols for youth internalizing disorders, (2) evaluate the acceptability and feasibility of the module with an eye toward intervention refinement, and (3) examine reductions in perceived burdensomeness. Participants were 18 clinic-referred youths with anxiety or depressive disorders who endorsed burdensomeness. The study utilized a quasi-experimental interrupted time-series design to evaluate changes in burdensomeness scores following the administration of the module. The module was clinically feasible and well-accepted. Youth burdensomeness scores increased in the first half of the CBT protocol, and decreased immediately following the administration of the Give program module. The current study is the first to develop and evaluate a selective preventive module targeting burdensomeness in at-risk youth in an outpatient setting, demonstrating that burdensomeness can be efficiently and effectively targeted within existing evidence-based treatment protocols for internalizing disorders in youth

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

Self-reported COVID-19 symptoms and perceived likelihood of suicide attempt among Latinx individuals who experience acculturative stress

The impact of COVID-19 has led to a substantial economic and psychosocial burden on the Latinx population. However, few studies have evaluated how COVID-19 symptoms may exacerbate suicide risk indicators among Latinx persons, or the particular social determinants of health facilitating such detrimental effects. The present study examined the association between self-reported COVID-19 symptoms and suicide likelihood (i.e., self-reported perceived likelihood that one will attempt suicide in the future) among Latinx individuals within a timeframe involving high COVID-19 contagion before the onset of vaccine dissemination. Further, the possible moderating role of acculturative stress in the association between COVID-19 symptoms and suicide likelihood was examined. The sample included 200 Latinx participants (67.5% male, Mage = 34.67 years, SD = 9.15) who completed self-report measures on COVID-19 symptoms, suicide likelihood, acculturative stress, depressive symptoms, trauma symptoms, somatic symptoms, and general COVID-19 emotional impact. Findings indicated that self-reported COVID-19 symptoms were positively associated with suicide likelihood. Further, the association between COVID-19 symptoms and suicide likelihood was moderated by acculturative stress, such that the association was only statistically significant at mean or higher levels of acculturative stress but was not significant among participants with lower acculturative stress. The moderation effect was statistically significant after controlling for sociodemographic factors, depressive symptoms, trauma symptoms, somatic symptoms, and the general emotional impact of the COVID-19 pandemic. The current findings indicate that, among Latinx individuals, acculturative stress is a key social determinant of health for marked psychological distress in the context of the COVID-19 pandemic

Documenting the Recovery of Vascular Services in European Centres Following the Initial COVID-19 Pandemic Peak: Results from a Multicentre Collaborative Study

Objective: To document the recovery of vascular services in Europe following the first COVID-19 pandemic peak. Methods: An online structured vascular service survey with repeated data entry between 23 March and 9 August 2020 was carried out. Unit level data were collected using repeated questionnaires addressing modifications to vascular services during the first peak (March - May 2020, "period 1"), and then again between May and June ("period 2") and June and July 2020 ("period 3"). The duration of each period was similar. From 2 June, as reductions in cases began to be reported, centres were first asked if they were in a region still affected by rising cases, or if they had passed the peak of the first wave. These centres were asked additional questions about adaptations made to their standard pathways to permit elective surgery to resume. Results: The impact of the pandemic continued to be felt well after countries' first peak was thought to have passed in 2020. Aneurysm screening had not returned to normal in 21.7% of centres. Carotid surgery was still offered on a case by case basis in 33.8% of centres, and only 52.9% of centres had returned to their normal aneurysm threshold for surgery. Half of centres (49.4%) believed their management of lower limb ischaemia continued to be negatively affected by the pandemic. Reduced operating theatre capacity continued in 45.5% of centres. Twenty per cent of responding centres documented a backlog of at least 20 aortic repairs. At least one negative swab and 14 days of isolation were the most common strategies used for permitting safe elective surgery to recommence. Conclusion: Centres reported a broad return of services approaching pre-pandemic "normal" by July 2020. Many introduced protocols to manage peri-operative COVID-19 risk. Backlogs in cases were reported for all major vascular surgeries

Relative particle yield fluctuations in Pb-Pb collisions at sNN=2.76\sqrt{s_{\rm NN}} = 2.76 TeV

First results on K/$\pi$, p/$\pi$ and K/p fluctuations are obtained with the ALICE detector at the CERN LHC as a function of centrality in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV. The observable $\nu_{\rm dyn}$, which is defined in terms of the moments of particle multiplicity distributions, is used to quantify the magnitude of dynamical fluctuations of relative particle yields and also provides insight into the correlation between particle pairs. This study is based on a novel experimental technique, called the Identity Method, which allows one to measure the moments of multiplicity distributions in case of incomplete particle identification. The results for p/$\pi$ show a change of sign in $\nu_{\rm dyn}$ from positive to negative towards more peripheral collisions. For central collisions, the results follow the smooth trend of the data at lower energies and $\nu_{\rm dyn}$ exhibits a change in sign for p/$\pi$ and K/p.First results on $\hbox {K}/\pi$ , $\hbox {p}/\pi$ and K/p fluctuations are obtained with the ALICE detector at the CERN LHC as a function of centrality in $\text{ Pb--Pb }$ collisions at $\sqrt{s_\mathrm{{NN}}} =2.76\hbox { TeV}$ .

Suppression of Λ(1520) resonance production in central Pb–Pb collisions at √sNN = 2.76 TeV

The production yield of the Λ(1520) baryon resonance is measured at mid-rapidity in Pb-Pb collisions at sNN−−−√ = 2.76 TeV with the ALICE detector at the LHC. The measurement is performed in the Λ(1520)→pK− (and charge conjugate) hadronic decay channel as a function of the transverse momentum (pT) and collision centrality. The pT-integrated production rate of Λ(1520) relative to Λ in central collisions is suppressed by about a factor of 2 with respect to peripheral collisions. This is the first observation of the suppression of a baryonic resonance at the LHC and the first 3σ evidence of Λ(1520) suppression within a single collision system. The measured Λ(1520)/Λ ratio in central collisions is smaller than the value predicted by the statistical hadronisation model calculations. The shape of the measured pT distribution and the centrality dependence of the suppression are reproduced by the EPOS3 Monte Carlo event generator. The measurement adds further support to the formation of a dense hadronic phase in the final stages of the evolution of the fireball created in heavy-ion collisions, lasting long enough to cause a significant reduction in the observable yield of short-lived resonances
