We used quantitative genetic methods to evaluate whether sleep quality, pain, and depression symptoms share a common genetic diathesis, to estimate the genetic and environmental sources of covariance among these symptoms, and to test for possible causal relationships.A community sample of 400 twins from the University of Washington Twin Registry completed standardized self-report questionnaires. We used biometric modeling to assess genetic and environmental contribution to the association between sleep quality measured by the Pittsburgh Sleep Quality Index (PSQI), pain measured by the Brief Pain Inventory (BPI), and depression symptoms measured by the Brief Symptom Inventory (BSI-dep). Trivariate Cholesky structural equation models were used to decompose correlations among the phenotypes.Heritability was estimated at 37% (95% CI: 20, 51%) for sleep quality, 25% (9, 41%) for pain, and 39% (22, 53%) for depression. Non-shared environmental influences accounted for the remaining variance. The genetic correlation between sleep quality and pain was rg = 0.69 (95%CI: 0.33, 0.97), rg = 0.56 (0.55, 0.98) between pain and depression, and rg = 0.61 (0.44, 0.88) between depression and sleep quality. Non-shared environmental overlap was present between pain and sleep quality and depression and sleep quality.The link between sleep quality, pain, and depression was primarily explained by shared genetic influences. The genetic factors influencing sleep quality and pain were highly correlated even when accounting for depression. Findings support the hypothesis of a genetic link between sleep quality and pain and potential causality for the association of sleep quality with pain and depression.

Youth suicide is increasing in the United States, with deaths among younger people of color driving this upward trend. For more than four decades, American Indian and Alaska Native (AIAN) communities have suffered disproportionate rates of youth suicide and years of productive life lost compared to other U.S. Races. The National Institute of Mental Health (NIMH) recently funded three regional Collaborative Hubs to carry out suicide prevention research, practice, and policy development with AIAN communities in Alaska and rural and urban areas of the Southwestern United States. The Hub partnerships are supporting a diverse array of tribally-driven studies, approaches, and policies with immediate value for increasing empirically driven public health strategies to address youth suicide. We discuss unique features of the cross-Hub work, including: (a) long-standing Community-Based Participatory Research processes that led to the Hubs' innovative designs and novel approaches to suicide prevention and evaluation, (b) comprehensive ecological theoretical approaches that contextualize individual risk and protective factors in multilevel social contexts; (c) unique task-shifting and systems of care approaches to increase reach and impact on youth suicide in low-resource settings; and (d) prioritization of strengths-based approaches. The work of the Collaborative Hubs for AIAN youth suicide prevention is generating specific and substantive implications for practice, policy, and research presented in this article at a time when youth suicide prevention is a dire national priority. Approaches also have relevance for historically marginalized communities worldwide. [ABSTRACT FROM AUTHOR]

AIMS: To determine whether symptoms of post-traumatic stress disorder (PTSD) are related to the pain of temporomandibular disorders (TMD) in a community-based sample of female twin pairs, and if so, to ascertain whether the association is due to the presence of chronic widespread pain (CWP) and familial/genetic factors. METHODS: Data were obtained from 630 monozygotic and 239 dizygotic female twin pairs participating in the University of Washington Twin Registry. PTSD symptoms were assessed with the Impact of Events Scale (IES), with scores partitioned into terciles. TMD pain was assessed with a question about persistent or recurrent pain in the face, jaw, temple; in front of the ear; or in the ear during the past 3 months. CWP was defined as pain located in 3 body regions during the past 3 months. Random-effects regression models, adjusted for demographic features, depression, CWP, and familial/genetic factors, were used to examine the relationship between the IES and TMD pain. RESULTS: IES scores were significantly associated with TMD pain (P < .01). Twins in the highest IES tercile were almost 3 times more likely than those in the lowest tercile to report TMD pain, even after controlling for demographic factors, depression, and CWP. After adjustment for familial and genetic factors, the association of IES scores with TMD pain remained significant in dizygotic twins (Ptrend = .03) but was not significant in monozygotic twins (Ptrend = .30). CONCLUSION: PTSD symptoms are strongly linked to TMD pain. This association could be partially explained by genetic vulnerability to both conditions but is not related to the presence of CWP. Future research is needed to understand the temporal association of PTSD and TMD pain and the genetic and physiological underpinnings of this relationship. [ABSTRACT FROM AUTHOR]

Background: Extracorporeal life support (ECLS) devices maintain the circulation and oxygenation of organs during acute right ventricular failure and cardiogenic shock, bypassing the lungs. A pulmonary embolism can cause this life-threatening condition. ECLS is a considerably less invasive treatment than surgical embolectomy. Whether to bridge embolectomy or for a therapeutic purpose, ECLS is used almost exclusively following failure of all other therapeutic options. Methods: From January 1, 2008 to June 30, 2014, five patients in cardiac arrest and with diagnosed pulmonary embolism (PE) were cannulated with the ECLS system. Results: PE was diagnosed using computer tomography scanning or echocardiography. Cardiac arrest was witnessed in the hospital in all cases and CPR (cardiopulmonary resuscitation) was initiated immediately. Cannulation of the femoral vein and femoral artery was always performed under CPR conditions. Right heart failure regressed during the ECLS therapy, usually under a blood flow of 4-5 L/min after 48 hours. Three patients were weaned from ECLS and one patient became an organ donor. Finally, two of the five PE patients treated with ECLS were discharged from inpatient treatment without neurological dysfunction. The duration of ECLS therapy depends on the patient’s condition. Irreversible damage to the organs after hypoxemia limits ECLS treatment and leads to futile multiorgan failure. Hemorrhages after thrombolysis and cerebral dysfunction were further complications. Conclusions: Veno-arterial cannulation for ECLS can be feasibly achieved and should be established during active CPR for cardiac arrest. In the case of PE, the immediate diagnosis and rapid implantation of the system are decisive for therapeutic success. [ABSTRACT FROM AUTHOR]

Purpose: Unexplained clinical conditions share features, including symptoms (fatigue, pain), disability out of proportion to physical examination findings, inconsistent demonstration of laboratory abnormalities, and an association with "stress" and psychosocial factors. This literature review examines the nature and extent of the overlap among these unexplained clinical conditions and the limitations of previous research.Data Sources: English-language articles were identified by a search of the MEDLINE database from 1966 to January 2001 by using individual syndromes and their hallmark symptoms as search terms.Study Selection: Studies that assessed patients with at least one unexplained clinical condition and that included information on symptoms, overlap with other unexplained clinical conditions, or physiologic markers. Conditions examined were the chronic fatigue syndrome, fibromyalgia, the irritable bowel syndrome, multiple chemical sensitivity, temporomandibular disorder, tension headache, interstitial cystitis, and the postconcussion syndrome.Data Extraction: Information on authorship, patient and control groups, eligibility criteria, case definitions, study methods, and major findings.Data Synthesis: Many similarities were apparent in case definition and symptoms, and the proportion of patients with one unexplained clinical condition meeting criteria for a second unexplained condition was striking. Tender points on physical examination and decreased pain threshold and tolerance were the most frequent and consistent objective findings. A major shortcoming of all proposed explanatory models is their inability to account for the occurrence of unexplained clinical conditions in many affected patients.Conclusions: Overlap between unexplained clinical conditions is substantial. Most studies are limited by methodologic problems, such as case definition and the selection and recruitment of case-patients and controls. [ABSTRACT FROM AUTHOR]

Introduction: Rates of nicotine use are high in American Indians. Anxiety and depression tend to be associated with cigarette use, but the association of anxiety and depression with smokeless tobacco (ST) is less clear. We asked if panic disorder, major depression, and posttraumatic stress disorder (PTSD) are related to lifetime ST use in 2 American Indian tribes.Methods: Logistic regression analyses examined the association between lifetime panic disorder, major depression, and PTSD and the odds of lifetime ST use status after controlling for sociodemographic characteristics, smoking status, and alcohol use disorders in 1,506 Northern Plains and 1,268 Southwest tribal members.Results: Odds of lifetime ST use was 1.6 times higher in Northern Plains tribal members with a lifetime history of PTSD after controlling for sociodemographic variables and smoking (95% CI: 1.1, 2.3; p = .01). This association remained significant after further adjustment for panic disorder and major depression (odds ratio [OR] = 1.5; 95% CI: 1.0, 2.2; p = .04) but was diminished after accounting for alcohol use (OR = 1.3; 95% CI: 0.9, 1.9; p = .23). In the Southwest, lifetime psychiatric disorders were not associated with lifetime ST use status. Increasing psychiatric comorbidity was significantly linked to increased odds of ST use in both tribes.Conclusions: This study is the first to examine psychiatric conditions and lifetime ST use in a large, geographically diverse American Indian community sample. Although approximately 30% of tribal members were lifetime users of ST, the association with lifetime psychiatric disorders was not as strong as those observed with cigarette smoking. Understanding shared mechanisms between all forms of tobacco use with anxiety and depressive disorders remains an important area for investigation. [ABSTRACT FROM AUTHOR]

Chronic fatigue syndrome (CFS) and unexplained chronic fatigue (CF) are characterized by compromised functional status and physical disability. Prior research on chronic pain has suggested that social factors may contribute to disability. This study examined the relationship between significant other responses and patient outcomes in patients with unexplained CF. Questionnaire data were collected from 117 patients on physical function, fatigue, pain, illness behaviors and responses of significant others to them, and depression. Ninety-four SOs reported their perceptions of patient illness behavior and their responses. Thirty-seven of these dyads also completed a series of household activities while being videotaped. Dyadic interactions were coded and analyzed. Both reported and observed solicitous responses by the significant other were associated with reported and observed patient illness behavior. Negative responses to patient illness behavior by significant others were associated with higher levels of patient depressive symptoms. The findings provide support for the role of operant behavioral factors in the context of chronic fatigue. They also suggest that further research on the relationship between dysfunction and significant other responses in patients with CFS or CF appears warranted and may have implications for treatment development.
