Prevalence and predictors of suicidality among adults initiating office-based buprenorphine.

BACKGROUND: Individuals who have substance use disorders may have an elevated risk of suicidality. This study sought to examine the prevalence of, and identify factors associated with, suicidality in adults with opioid use disorder (OUD) initiating office-based buprenorphine treatment. METHODS: Individuals were eligible to participate if they had OUD and had initiated treatment in the past month. Participants (n = 244) completed a semi-structured interview using the Addiction Severity Index-Lite. RESULTS: At baseline, 37.70% of participants reported significant thoughts of suicide over their lifetime and 27.46% reported suicidal attempts over their lifetime. Logistic regression analyses were used to identify predictors of lifetime suicidal thoughts and attempts. A history of physical abuse (OR = 4.31, p \u3c .001), having chronic pain-related conditions (OR = 3.28, p \u3c .001), a history of depression (OR = 3.30, p = .001) or anxiety (OR = 7.47, p = .001), and Latino/a/x ethnicity (OR = 2.66, p = .01) were associated with an increased risk of lifetime suicidal thoughts. A history of sexual abuse (OR = 2.89, p = .01), Latino/a/x ethnicity (OR = 4.01, p \u3c .001), a history of depression (OR = 4.03, p = .001) or anxiety (OR = 15.65, p = .007) and having a chronic pain-related condition (OR = 2.43, p = .01), were associated with an increased risk of lifetime suicide attempts. CONCLUSIONS: Results demonstrate the high prevalence of suicidal thoughts and attempts among patients initiating buprenorphine. Findings may help to better identify at-risk patients and to inform screening, prevention, and mental health treatment efforts.

Self-organization of quantum-dot pairs by high-temperature droplet epitaxy

The spontaneously formation of epitaxial GaAs quantum-dot pairs was demonstrated on an AlGaAs surface using Ga droplets as a Ga nano-source. The dot pair formation was attributed to the anisotropy of surface diffusion during high-temperature droplet epitaxy

Characteristics of undiagnosed diseases network applicants: implications for referring providers

Abstract Background The majority of undiagnosed diseases manifest with objective findings that warrant further investigation. The Undiagnosed Diseases Network (UDN) receives applications from patients whose symptoms and signs have been intractable to diagnosis; however, many UDN applicants are affected primarily by subjective symptoms such as pain and fatigue. We sought to characterize presenting symptoms, referral sources, and demographic factors of applicants to the UDN to identify factors that may determine application outcome and potentially differentiate between those with undiagnosed diseases (with more objective findings) and those who are less likely to have an undiagnosed disease (more subjective symptoms). Methods We used a systematic retrospective review of 151 consecutive Not Accepted and 50 randomly selected Accepted UDN applications. The primary outcome was whether an applicant was Accepted, or Not Accepted, and, if accepted, whether or not a diagnosis was made. Objective and subjective symptoms and information on prior specialty consultations were collected from provider referral letters. Demographic data and decision data on network acceptance were gathered from the UDN online portal. Results Fewer objective findings and more subjective symptoms were found in the Not Accepted applications. Not Accepted referrals also were from older individuals, reported a shorter period of illness, and were referred to the UDN by their primary care physicians. All of these differences reached statistical significance in comparison with Accepted applications. The frequency of subspecialty consults for diagnostic purposes prior to UDN application was similar in both groups. Conclusions The preponderance of subjective and lack of objective findings in the Not Accepted applications distinguish these from applicants that are accepted for evaluation and diagnostic efforts through the UDN. Not Accepted applicants are referred primarily by their primary care providers after multiple specialist consultations fail to yield answers. Distinguishing between patients with undiagnosed diseases with objective findings and those with primarily subjective findings can delineate patients who would benefit from further diagnostic processes from those who may have functional disorders and need alternative pathways for management of their symptoms.

Extended Theories of Gravity

Extended Theories of Gravity can be considered a new paradigm to cure shortcomings of General Relativity at infrared and ultraviolet scales. They are an approach that, by preserving the undoubtedly positive results of Einstein's Theory, is aimed to address conceptual and experimental problems recently emerged in Astrophysics, Cosmology and High Energy Physics. In particular, the goal is to encompass, in a self-consistent scheme, problems like Inflation, Dark Energy, Dark Matter, Large Scale Structure and, first of all, to give at least an effective description of Quantum Gravity. We review the basic principles that any gravitational theory has to follow. The geometrical interpretation is discussed in a broad perspective in order to highlight the basic assumptions of General Relativity and its possible extensions in the general framework of gauge theories. Principles of such modifications are presented, focusing on specific classes of theories like f (R)-gravity and scalar-tensor gravity in the metric and Palatini approaches. The special role of torsion is also discussed. The conceptual features of these theories are fully explored and attention is payed to the issues of dynamical and conformal equivalence between them considering also the initial value problem. A number of viability criteria are presented considering the post-Newtonian and the post-Minkowskian limits. In particular, we discuss the problems of neutrino oscillations and gravitational waves in Extended Gravity. Finally, future perspectives of Extended Gravity are considered with possibility to go beyond a trial and error approach.Comment: 184 pages, 3 figures, survey to appear in Physics Report
