Depressive symptoms and impaired physical function after acute lung injury: a 2-year longitudinal study.

ABSTRACT: Survivors of acute lung injury (ALI) frequently have substantial depressive symptoms and physical impairment, but the longitudinal epidemiology of these conditions remains unclear.To evaluate the 2-year incidence and duration of depressive symptoms and physical impairment after ALI, as well as risk factors for these conditions.This prospective, longitudinal cohort study recruited patients from 13 intensive care units (ICUs) in four hospitals, with follow-up 3, 6, 12, and 24 months after ALI. The outcomes were Hospital Anxiety and Depression Scale depression score greater than or equal to 8 ("depressive symptoms") in patients without a history of depression before ALI, and two or more dependencies in instrumental activities of daily living ("impaired physical function") in patients without baseline impairment.During 2-year follow-up of 186 ALI survivors, the cumulative incidences of depressive symptoms and impaired physical function were 40 and 66%, respectively, with greatest incidence by 3-month follow-up; modal durations were greater than 21 months for each outcome. Risk factors for incident depressive symptoms were education 12 years or less, baseline disability or unemployment, higher baseline medical comorbidity, and lower blood glucose in the ICU. Risk factors for incident impaired physical function were longer ICU stay and prior depressive symptoms.Incident depressive symptoms and impaired physical function are common and long-lasting during the first 2 years after ALI. Interventions targeting potentially modifiable risk factors (e.g., substantial depressive symptoms in early recovery) should be evaluated to improve ALI survivors' long-term outcomes.

Project description:To evaluate the cooccurrence, and predictors of remission, of general anxiety, depression, and posttraumatic stress disorder symptoms during 2-year follow-up in survivors of acute lung injury treated in an ICU.Prospective cohort study, with follow-up at 3, 6, 12, and 24 months post-acute lung injury.Thirteen medical and surgical ICUs in four hospitals.Survivors among 520 patients with acute lung injury.The outcomes of interest were measured using the Hospital Anxiety and Depression Scale anxiety and depression subscales (scores ? 8 indicating substantial symptoms) and the Impact of Event Scale-Revised (scores ? 1.6 indicating substantial posttraumatic stress disorder symptoms). Of the 520 enrolled patients, 274 died before 3-month follow-up; 186 of 196 consenting survivors (95%) completed at least one Hospital Anxiety and Depression Scale and Impact of Event Scale-Revised assessment during 2-year follow-up, and most completed multiple assessments. Across follow-up time points, the prevalence of suprathreshold general anxiety, depression, and posttraumatic stress disorder symptoms ranged from 38% to 44%, 26% to 33%, and 22% to 24%, respectively; more than half of the patients had suprathreshold symptoms in at least one domain during 2-year follow-up. The majority of survivors (59%) with any suprathreshold symptoms were above threshold for two or more types of symptoms (i.e., general anxiety, depression, and/or posttraumatic stress disorder). In fact, the most common pattern involved simultaneous general anxiety, depression, and posttraumatic stress disorder symptoms. Most patients with general anxiety, depression, or posttraumatic stress disorder symptoms during 2-year follow-up had suprathreshold symptoms at 24-month (last) follow-up. Higher Short-Form-36 physical functioning domain scores at the prior visit were associated with a greater likelihood of remission from general anxiety and posttraumatic stress disorder symptoms during follow-up.The majority of acute lung injury survivors had clinically significant general anxiety, depression, or posttraumatic stress disorder symptoms, and these symptoms tended to co-occur across domains. Better physical functioning during recovery predicted subsequent remission of general anxiety and posttraumatic stress disorder symptoms.

Project description:BACKGROUND:The direction of the association between inflammation and depressive symptoms remains inconsistent. The objective of this study was to evaluate the temporal relationship between inflammation and depressive symptoms, and to assess the role of genetic factors on this association. METHODS:In this longitudinal cross-lagged twin difference study, we examined 166 (83 pairs) middle-aged male twins recruited from the Vietnam Era Twin Registry, who were assessed at baseline and after 7?years of follow-up. We assayed plasma levels of two inflammatory biomarkers, interleukin-6 (IL-6) and high sensitivity C-reactive protein (CRP) and measured depressive symptoms using the Beck Depression Inventory-II (BDI). To evaluate the direction of the association, we constructed multivariable mixed-effects regression models and calculated standardized beta-coefficients to compare the strength of the within-pair association for both pathways. We then conducted a stratified analysis by zygosity and assessed the associations in monozygotic and dizygotic twin pairs separately. RESULTS:The 166 twins were 95% white and had a mean (SD) age of 54 (3) years at baseline. The cross-lagged analysis showed significant and positive associations from visit 1 IL-6 to visit 2 BDI across all models (beta-coefficients ranging from 0.18 to 0.22). However, the opposite pathway (visit 1 BDI to visit 2 IL-6) was not significant after adjusting for confounding factors. In contrast, visit 1 BDI was significantly associated with visit 2 CRP in all models (beta-coefficients ranging from 0.23 to 0.33), while the opposite pathway (visit 1 CRP to visit 2 BDI) showed no significant association. When stratifying by zygosity, significant associations from IL-6 to depression were only seen in monozygotic twins, but associations from depression to CRP were more robust in dizygotic twins, which implies that genetic factors may play a role in this association. CONCLUSIONS:The association between inflammation and depression may be bidirectional. Elevated IL-6 levels are more likely to be a risk factor of depression rather than a consequence, while the opposite may be true for elevated CRP. The biological underpinnings of these bidirectional pathways need further evaluation.

Project description:An increased risk of depressive symptoms has been associated with the transition to menopause, but the risk of depressive symptoms in the early postmenopausal years has not been well characterized.To identify within-woman changes in depressive symptoms during a 14-year period around menopause, determine associations of a history of depression with the pattern of depressive symptoms, and evaluate the rate of change in reproductive hormones as predictors of depressive symptoms following menopause.A randomly identified, population-based sample in Philadelphia County, Pennsylvania, of 203 late-reproductive-age women who were premenopausal at baseline and reached natural menopause.Center for Epidemiologic Studies Depression Scale.The prevalence of high scores on the Center for Epidemiologic Studies Depression Scale decreased from 10 years before to 8 years after the final menstrual period (FMP), with a decrease of approximately 15% of baseline per year (odds ratio, 0.85; 95% CI, 0.81-0.89; P?<?.001). Relative to the FMP, the risk of depressive symptoms was higher in the years before and lower in the years after the FMP. Among women with a history of depression, the likelihood of depressive symptoms was more than 13 times greater overall and 8 times greater after menopause compared with women with no depression history. Among women who first experienced depressive symptoms approaching menopause, the risk of depressive symptoms declined after the FMP, with a significantly lower risk the second year after menopause. The risk of depressive symptoms after menopause decreased by 35% for each unit (SD) increase before the FMP in the log rate of change of follicle-stimulating hormone (odds ratio, 0.65; 95% CI, 0.46-0.91; P?=?.01).The FMP was pivotal in the overall pattern of decreasing depressive symptoms in midlife women, with higher risk before and lower risk after the FMP. A history of depression strongly increased the risk both before and after menopause. Women who had no history of depression before the menopause transition had a low risk of depressive symptoms 2 or more years after the FMP.
