Multifaceted associations between walking performance, physical fitness, extremity function, health status, and depression in individuals with COPD. Ann Med 2024; 56:2338248. [PMID: 38590164 PMCID: PMC11005873 DOI: 10.1080/07853890.2024.2338248] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 03/06/2024] [Indexed: 04/10/2024] Open
Abstract
BACKGROUND/OBJECTIVE(S) Chronic obstructive pulmonary disease (COPD) can precipitate a deterioration of an individual's physical performance and overall health. Evidence suggests that, along with pulmonary functions, several other factors are related to the significant impairment of walking performance in individuals with COPD. This study compared the depressive symptoms, health status, upper and lower extremity functions, and peak oxygen uptake (VO2peak) in a group of individuals with COPD based on walking performance using a cutoff distance of 350 m in the six-minute walking test (6MWT). The study also investigated the associations between these factors and walking performance. MATERIALS AND METHODS Participants performed the 6MWT according to the guidelines and were classified into high (>350 m; n = 40) or low (<350 m; n = 30) walking performance groups according to distance. The forced expiratory volume (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio were recorded. Participants completed the Patient Health Questionnaire-9 (PHQ-9), St. George's Respiratory Questionnaire (SGRQ), and the Upper and Lower Extremity Functional Index (UEFI/LEFI). Predicted VO2peak was measured using the Duke Activity Status Index (DASI). RESULTS Seventy participants with a mean age of 63 ± 11 years (20% female) were enrolled in this study. Patients with high walking performance demonstrated significantly better health status than those with low walking performance (SGRQ: 49 ± 25 vs. 56 ± 21, p = 0.03). Participants with low walking performance had lower predicted VO2peak compared to their higher performing counterparts (p = 0.002). The overall model was significant (F(8, 61) = 7.48, p = 0.0006), with PHQ-9, SGRQ, UEFI/LEFI, VO2peak, and FEV1/FVC explaining approximately 49.5% of the variance in the 6MWT distance. CONCLUSION This study shed light on the association of depressive symptoms, health status, extremity function, and VO2peak with walking performance, providing valuable insights that may impact the management and care of individuals with COPD.

Impact of SARS-CoV-2 Infection on Long-Term Depression Symptoms among Veterans. J Gen Intern Med 2024:10.1007/s11606-024-08630-z. [PMID: 38625482 DOI: 10.1007/s11606-024-08630-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Accepted: 01/11/2024] [Indexed: 04/17/2024]
Abstract
BACKGROUND Prior research demonstrates that SARS-COV-2 infection can be associated with a broad range of mental health outcomes including depression symptoms. Veterans, in particular, may be at elevated risk of increased depression following SARS-COV-2 infection given their high rates of pre-existing mental and physical health comorbidities. However, few studies have tried to isolate SARS-COV-2 infection associations with long term, patient-reported depression symptoms from other factors (e.g., physical health comorbidities, pandemic-related stress). OBJECTIVE To evaluate the association between SARS-COV-2 infection and subsequent depression symptoms among United States Military Veterans. DESIGN Survey-based non-randomized cohort study with matched comparators. PARTICIPANTS A matched-dyadic sample from a larger, stratified random sample of participants with and without known to SARS-COV-2 infection were invited to participate in a survey evaluating mental health and wellness 18-months after their index infection date. Sampled participants were stratified by infection severity of the participant infected with SARS-COV-2 (hospitalized or not) and by month of index date. A total of 186 participants in each group agreed to participate in the survey and had sufficient data for inclusion in analyses. Those in the uninfected group who were later infected were excluded from analyses. MAIN MEASURES Participants were administered the Patient Health Questionnaire-9 as part of a phone interview survey. Demographics, physical and mental health comorbidities were extracted from VHA administrative data. KEY RESULTS Veterans infected with SARS-COV-2 had significantly higher depression symptoms scores compared with those uninfected. In particular, psychological symptoms (e.g., low mood, suicidal ideation) scores were elevated relative to the comparator group (MInfected = 3.16, 95%CI: 2.5, 3.8; MUninfected = 1.96, 95%CI: 1.4, 2.5). Findings were similar regardless of history of depression. CONCLUSION SARS-COV-2 infection was associated with more depression symptoms among Veterans at 18-months post-infection. Routine evaluation of depression symptoms over time following SARS-COV-2 infection is important to facilitate adequate assessment and treatment.

Abstract
The impact of climate change on tourism has always been an important topic for research in the field of international tourism, and haze has been widely recognized as the primary negative factor affecting the development of inbound tourism in China. In this study, we first conduct a theoretical analysis of the mechanism through which haze influences the tourism industry, and then we empirically analyze the impact on China's inbound tourism using surface particulate matter (PM2.5) concentrations as a proxy for haze, based on provincial panel data from 1998 to 2016. The empirical results show that haze not only has an inhibitory effect on inbound tourism, but also significantly reduces the average length of stay of international tourists. In addition, while there are significant regional differences in the crowding-out effect of haze pollution on inbound tourism, the effect varies depending on the origin of inbound tourists, exhibiting the greatest negative impact on inbound tourism from Taiwan and the smallest from foreign countries. Our research highlights that haze pollution can led to the change of human tourism behavior which enrich the literature on tourism and haze.

The Effect of Kitchen Ventilation Modification on Independent and Combined Associations of Cooking Fuel Type and Cooking Duration with Suicidal Ideation: A Cross-Sectional Study. TOXICS 2022; 10:721. [PMID: 36548554 PMCID: PMC9788604 DOI: 10.3390/toxics10120721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 11/18/2022] [Accepted: 11/22/2022] [Indexed: 06/17/2023]
Abstract
Although household air pollution (HAP) is associated with an increased risk of mental disorders, evidence remains scarce for the relationship between HAP and suicidal ideation. A total of 21,381 qualified participants were enrolled on the Henan Rural Cohort Study. HAP information including cooking fuel type, cooking duration and kitchen ventilation was collected by questionnaires. Suicidal ideation was evaluated by item nine of the Patient Health Questionnaire-9 (PHQ-9). Independent and combined associations of cooking fuel type and cooking duration with suicidal ideation were explored by logistic regression models. Analyses were conducted in different kitchen ventilation groups to detect the potential effect modification. The adjusted odds ratio (OR) and 95% confidence interval (95% CI) of solid fuel users versus clean fuel users for suicidal ideation was 1.37 (1.16, 1.62), and the risk of suicidal ideation increased by 15% (95% CI: 5%, 26%) for each additional hour of the cooking duration. Participants cooking with solid fuel for long durations were related to the highest risk of suicidal ideation (OR (95% CI): 1.51 (1.22, 1.87)). However, all these associations were not observed in those cooking with mechanical ventilation. Mechanical ventilation ameliorated relationships between solid fuel use and long-duration cooking with suicidal ideation.

Abstract
Recently, there has been interest in the relationship between mental health and air pollution; however, the results are inconsistent and the contribution of foreign direct investment (FDI) has received little attention. This article studies the effects of air pollution on mental health and the moderating role of FDI based on the China Health and Retirement Longitudinal Study (CHARLS) data in 2015 and 2018 applying the fixed effects panel regression approach and the threshold model. The results show that mental health is adversely affected by air pollution, especially PM2.5, PM10, sulfur dioxide (SO2), carbon monoxide (CO), and nitrogen dioxide (NO2). Second, FDI has an alleviating influence on the negative relationship. Third, the effects of air pollution and FDI are heterogeneous based on regional characteristics, including location, medical resource and investment in science and technology, and individual characteristics covering education level, age, income, and physical health. Finally, the threshold effects show that FDI has a moderating effect when it is >1,745.59 million renminbi (RMB). There are only 11.19% of cities exceeding the threshold value in China. When the value of air quality index (AQI) exceeds 92.79, air pollution is more harmful to mental health. Government should actively introduce high-quality FDI at the effective level and control air pollution to improve mental health.

Abstract
The effects of air pollution on population health are currently a hot topic. However, few studies have examined the physical and mental health effects of air pollution jointly in China. Using data from the China Health and Retirement Longitudinal Study (CHARLS) in 2015 and 2018, this study explores how air pollution affects the physical and mental health of middle-aged and elderly residents. The empirical results highlight that air pollution can negatively affect both physical and mental health. In terms of physical health, those exposed to chronic shock are likely to suffer more adverse effects from air pollution than those exposed to acute shock. In terms of mental health, those exposed to depression suffer greater adverse effects than those exposed to episodic memory and mental cognition. Besides, heterogeneity analysis also shows that air pollution affects the mental and physical health of males more than females. Furthermore, the increase in air pollution is expected to result in huge hospitalization costs. Therefore, the Chinese government should formulate differentiated public health policies to reduce the effects of air pollution on the health of middle-aged and elderly residents.

Abstract
RATIONALE Benzodiazepines are associated with mortality and poor outcomes among patients with chronic obstructive pulmonary disease (COPD), but use of benzodiazepines for dyspnea among patients with end-stage disease may confound this relationship. OBJECTIVES Assess the mortality risks of long-term benzodiazepine exposure among patients with COPD and comorbid post-traumatic stress disorder (PTSD), patients with chronic nonrespiratory indications for benzodiazepines. METHODS We identified all patients with COPD and PTSD within the Veteran's Health Administration between 2010 and 2012. We calculated propensity scores for benzodiazepine use and compared overall and cause-specific mortality of patients with long-term (≥90 d) benzodiazepine use relative to matched patients without use. Secondary analyses assessed propensity-adjusted survival by characteristics of benzodiazepine exposure. RESULTS Among 44,555 eligible patients with COPD and PTSD, 23.6% received benzodiazepines long term. In the matched sample of 19,552 patients, we observed no mortality difference (hazard ratio [HR] for long-term use, 1.06; 95% confidence interval [CI], 0.95-1.18) but greater risk of death by suicide among those with long-term use (HR, 2.33; 95% CI, 1.14-4.79). Among matched and unmatched patients, short-term benzodiazepine use, but not long-term use, was associated with increased mortality (short-term: HR, 1.16; 95% CI, 1.05-1.28; long-term: HR, 1.03; 95% CI, 0.94-1.13). CONCLUSIONS Risks for respiratory compromise related to long-term benzodiazepine use in COPD may be less than previously estimated, but short-term use of benzodiazepines could still pose a mortality risk. Suicide associated with benzodiazepine use in this population warrants further investigation.

Health perspectives among Halabja's civilian survivors of sulfur mustard exposure with respiratory symptoms-A qualitative study. PLoS One 2019; 14:e0218648.

Abstract
Background In 1988, Halabja came under heavy chemical warfare attack using chemicals such as sulfur mustard (SM). Thousands of survivors of SM exposure in the city today live with multiple health complaints, such as severe, long-lasting respiratory symptoms; but their perceptions of health have never been adequately researched. We aimed to explore current major health concern topics in civilian survivors with long-term respiratory symptoms. Method Sixteen subjects (f:m10:6, mean age 45.5 years (range 34–67)) were interviewed. Study participants were recruited in 2016 via a purposive sampling strategy among civilian survivors of chemical warfare in the city of Halabja in Kurdistan-Iraq. A qualitative research design was applied including semi-structured, face-to-face interviews. Data was analyzed using systematic text condensation. Results The analysis yielded fourteen themes related to: (1) General health: all participants described a deterioration in physical and psychological health, following the SM exposure, foremost involving respiratory symptoms, fatigue, sleeping disorders, ocular problems, depressive symptoms, and anxiety; (2) Quality of life: most notably, they reported a limited family life, limited social relations, lack of work ability, and concern about their financial situation. Moreover, many lived in constant fear of a renewed attack; (3) access to health care services: all participants reported that they had no, or only poor, access to health care services and limited access to specialist care, and all reported lack of financial resources to obtain treatment. Conclusions The post-exposure somatic and psychosocial effects such as respiratory symptoms of CWA are plausible contributor to poor general health and quality of life among survivors. We conclude that multidisciplinary interventions are needed to tackle the biopsychosocial complications in survivors of SM exposure to minimize further health damage in the future, as well as to promote their health-related quality of life.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) has been recognised as a global health concern, and one of the leading causes of morbidity and mortality worldwide. Projections of the World Health Organization (WHO) indicate that prevalence rates of COPD continue to increase, and by 2030, it will become the world's third leading cause of death. Depression is a major comorbidity amongst patients with COPD, with an estimate prevalence of up to 80% in severe stages of COPD. Prevalence studies show that patients who have COPD are four times as likely to develop depression compared to those without COPD. Regrettably, they rarely receive appropriate treatment for COPD-related depression. Available findings from trials indicate that untreated depression is associated with worse compliance with medical treatment, poor quality of life, increased mortality rates, increased hospital admissions and readmissions, prolonged length of hospital stay, and subsequently, increased costs to the healthcare system. Given the burden and high prevalence of untreated depression, it is important to evaluate and update existing experimental evidence using rigorous methodology, and to identify effective psychological therapies for patients with COPD-related depression. OBJECTIVES To assess the effectiveness of psychological therapies for the treatment of depression in patients with chronic obstructive pulmonary disease. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2018, Issue 11), and Ovid MEDLINE, Embase and PsycINFO from June 2016 to 26 November 2018. Previously these databases were searched via the Cochrane Airways and Common Mental Disorders Groups' Specialised Trials Registers (all years to June 2016). We searched ClinicalTrials.gov, the ISRCTN registry, and the World Health Organization International Clinical Trials Registry Platform (ICTRP) to 26 November 2018 to identify unpublished or ongoing trials. Additionally, the grey literature databases and the reference lists of studies initially identified for full-text screening were also searched. SELECTION CRITERIA Eligible for inclusion were randomised controlled trials that compared the use of psychological therapies with either no intervention, education, or combined with a co-intervention and compared with the same co-intervention in a population of patients with COPD whose depressive symptoms were measured before or at baseline assessment. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the titles and abstracts identified by the search to determine which studies satisfied the inclusion criteria. We assessed two primary outcomes: depressive symptoms and adverse events; and the following secondary outcomes: quality of life, dyspnoea, forced expiratory volume in one second (FEV1), exercise tolerance, hospital length of stay or readmission rate, and cost-effectiveness. Potentially eligible full-text articles were also independently assessed by two review authors. A PRISMA flow diagram was prepared to demonstrate the decision process in detail. We used the Cochrane 'Risk of bias' evaluation tool to examine the risk of bias, and assessed the quality of evidence using the GRADE framework. All outcomes were continuous, therefore, we calculated the pooled standardised mean difference (SMD) or mean difference (MD) with a corresponding 95% confidence interval (CI). We used a random-effects model to calculate treatment effects. MAIN RESULTS The findings are based on 13 randomised controlled trials (RCTs), with a total of 1500 participants. In some of the included studies, the investigators did not recruit participants with clinically confirmed depression but applied screening criteria after randomisation. Hence, across the studies, baseline scores for depressive symptoms varied from no symptoms to severe depression. The severity of COPD across the studies was moderate to severe.Primary outcomesThere was a small effect showing the effectiveness of psychological therapies in improving depressive symptoms when compared to no intervention (SMD 0.19, 95% CI 0.05 to 0.33; P = 0.009; 6 studies, 764 participants), or to education (SMD 0.23, 95% CI 0.06 to 0.41; P = 0.010; 3 studies, 507 participants).Two studies compared psychological therapies plus a co-intervention versus the co-intervention alone (i.e. pulmonary rehabilitation (PR)). The results suggest that a psychological therapy combined with a PR programme can reduce depressive symptoms more than a PR programme alone (SMD 0.37, 95% CI -0.00 to 0.74; P = 0.05; 2 studies, 112 participants).We rated the quality of evidence as very low. Owing to the nature of psychological therapies, blinding of participants, personnel, and outcome assessment was a concern.None of the included studies measured adverse events.Secondary outcomesQuality of life was measured in four studies in the comparison with no intervention, and in three studies in the comparison with education. We found inconclusive results for improving quality of life. However, when we pooled data from two studies using the same measure, the result suggested that psychological therapy improved quality of life better than no intervention. One study measured hospital admission rates and cost-effectiveness and showed significant reductions in the intervention group compared to the education group. We rated the quality of evidence as very low for the secondary outcomes. AUTHORS' CONCLUSIONS The findings from this review indicate that psychological therapies (using a CBT-based approach) may be effective for treating COPD-related depression, but the evidence is limited. Depressive symptoms improved more in the intervention groups compared to: 1) no intervention (attention placebo or standard care), 2) educational interventions, and 3) a co-intervention (pulmonary rehabilitation). However, the effect sizes were small and quality of the evidence very low due to clinical heterogeneity and risk of bias. This means that more experimental studies with larger numbers of participants are needed, to confirm the potential beneficial effects of therapies with a CBT approach for COPD-related depression.New trials should also address the gap in knowledge related to limited data on adverse effects, and the secondary outcomes of quality of life, dyspnoea, forced expiratory volume in one second (FEV1), exercise tolerance, hospital length of stay and frequency of readmissions, and cost-effectiveness. Also, new research studies need to adhere to robust methodology to produce higher quality evidence.

Effect of COPD severity and comorbidities on the result of the PHQ-9 tool for the diagnosis of depression: results from the COSYCONET cohort study. Respir Res 2019; 20:30. [PMID: 30744630 PMCID: PMC6371561 DOI: 10.1186/s12931-019-0997-y] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Accepted: 02/04/2019] [Indexed: 01/01/2023] Open
Abstract
The diagnosis of depression, a frequent comorbidity of chronic obstructive pulmonary disease (COPD), is often supported by questionnaires, such as the Patient Health Questionnaire 9 (PHQ-9). It is unknown to which extent its single questions are affected by the clinical characteristics of COPD patients. We addressed this question in 2255 GOLD grade 1–4 patients from the COSYCONET (COPD and Systemic Consequences - Comorbidities Network) COPD cohort. The dependence on COPD severity was assessed using symptoms, exacerbation risk (GOLD A-D; modified Medical Research Council dyspnoea scale (mMRC)), and frequent comorbidities as predictors of PHQ-9 results, while including age, gender, body mass index (BMI) and smoking habits as covariates. Symptoms and exacerbation risk were associated with depression in an additive manner, with mean elevations in the PHQ-9 sum score by 2.75 and 1.44 points, respectively. Asthma, sleep apnoea, gastrointestinal disorders, osteoporosis and arthritis were linked to increases by 0.8 to 1.3 points. Overall, the COPD characteristics contributed to the mean PHQ-9 score by increases from 4.5 or 5.2 to 6.3 points, respectively, when either taking GOLD A as reference or the absence of comorbidities. This finding was independent of the diagnosis of mental disorder or the intake of antidepressants. The presence of COPD led to an increase in the proportion of scores indicating depression from 12 to 22%. Single item analysis revealed homogenous effects regarding GOLD groups, but heterogeneous effects regarding GOLD grades. These findings indicate specific effects of COPD severity on the PHQ-9 depression score, especially symptoms and exacerbation risk, explaining the high prevalence of depression in COPD. Alternative explanations like an overlap of COPD severity and PHQ-9 items are discussed. Of note, we also found COPD treatment effects on depression scores.

Abstract
BACKGROUND Studies report that up to 80% of individuals with chronic obstructive pulmonary disease (COPD) may struggle with symptoms of depression. However, this major comorbidity in COPD is rarely managed effectively. A number of recent studies indicate that left untreated, COPD-related depression is associated with worse quality of life, worse compliance with COPD treatment plan, increased exacerbations, hospital admissions, and healthcare costs when compared to individuals with COPD without depression. Regrettably, COPD practice guidelines do not provide conclusive treatment recommendations for the use of antidepressants in patients with COPD, and base their guidelines on findings from trials in the general population. This may be problematic, as there is an elevated risk of respiratory issues associated with antidepressant treatment and COPD. Evaluating effectiveness and safety of pharmacological interventions specifically for patients with COPD and depression was therefore paramount. OBJECTIVES To assess the effectiveness and safety of pharmacological interventions for the treatment of depression in patients with COPD. SEARCH METHODS The last search was performed on 26 November 2018. We initially searched the following databases via the Specialised Trials Registers of the Cochrane Airways and Common Mental Disorders Groups (to June 2016): MEDLINE, Embase, PsycINFO, CINAHL, AMED, and the Cochrane Library trials register (CENTRAL). Searches from June 2016 to November 2018 were performed directly on Ovid MEDLINE, Embase, PsycINFO and the Cochrane Library (Issue 11, 2018). We searched ClinicalTrials.gov, the ISRCTN registry, and the World Health Organization International Clinical Trials Registry Platform to 26 November 2018. We searched the grey literature databases to identify studies not indexed in major databases and the reference lists of studies initially identified for full-text screening. SELECTION CRITERIA All published and unpublished randomised controlled trials (RCTs) comparing the efficacy of pharmacological interventions with no intervention, placebo or co-intervention in adults with diagnosed COPD and depression were eligible for inclusion. DATA COLLECTION AND ANALYSIS Two review authors independently assessed articles identified by the search for eligibility. Our primary outcomes were change in depressive symptoms and adverse events. The secondary outcomes were: change in quality of life, change in dyspnoea, change in forced expiratory volume in one second (FEV1), change in exercise tolerance, change in hospital utilisation (length of stay and readmission rates), and cost-effectiveness. For continuous outcomes, we calculated the pooled mean difference (MD) or standardised mean difference (SMD) with 95% confidence interval (CI) as appropriate. For dichotomous outcomes, we calculated the pooled odds ratio (OR) and corresponding 95% CI using a random-effects model. We assessed the quality of evidence using the GRADE framework. MAIN RESULTS Of the 1125 records screened for eligibility, four RCTs (N = 201 participants), and one on-going study, met the inclusion criteria. Two classes of antidepressants were investigated in two separate comparisons with placebo: a tricyclic antidepressant (TCA) and selective serotonin reuptake inhibitors (SSRIs).TCA versus placeboOnly one RCT (N = 30 participants) provided results for this comparison.Primary outcomesThe TCA (nortriptyline) reduced depressive symptoms post-treatment compared to placebo (MD -10.20, 95% CI -16.75 to -3.65; P = 0.007; very low-quality evidence), as measured by the Hamilton Depression Rating Scale (HAM-D). Three participants withdrew from the trial due to adverse events related to the tested antidepressant (dry mouth, sedation, orthostatic hypotension).Secondary outcomesThe overall results post-treatment indicated that nortriptyline was not effective in improving the quality of life of individuals with COPD, as measured by the Sickness Impact Profile (MD -2.80, 95% CI -11.02 to 5.42; P = 0.50; very low-quality evidence).The results for the change in dyspnoea for the domains examined (e.g. dyspnoea scores for 'most day-to-day activities') post-treatment showed no improvement in the intervention group (MD 9.80, 95% CI -6.20 to 25.80; P = 0.23; very low-quality evidence).No data were reported for change in FEV1, change in exercise tolerance, change in hospital utilisation, or cost-effectiveness. The TCA study provided short-term results, with the last follow-up data collection at 12 weeks.The quality of the evidence for all the outcomes evaluated was very low due to a small sample size, imprecision, attrition, and selection and reporting bias.SSRIs versus placeboThree RCTs (N = 171 participants) provided results for this comparison.Primary outcomesThe pooled results for two studies showed no difference for the change in depressive symptoms post-intervention (SMD 0.75, 95% CI -1.14 to 2.64; 148 participants; 2 studies; P = 0.44; very low-quality evidence). High heterogeneity was observed (I² = 95%), limiting the reliability of these findings.While it was not possible to meta-analyse the total adverse events rates across the studies, it was possible to combine the results for two medication-specific adverse effects: nausea and dizziness. There were no significant post-treatment group differences for nausea (OR 2.32, 95% CI 0.66 to 8.12; 171 participants; 3 studies; P = 0.19; very low-quality evidence) or dizziness (OR 0.61, 95% CI 0.09 to 4.06; 143 participants; 2 studies; P = 0.61; very low-quality evidence).Secondary outcomesThe pooled analysis of two trials reporting data for the change in quality of life did not show improvement post-treatment in the intervention group compared to placebo (SMD 1.17, 95% CI -0.80 to 3.15; 148 participants; 2 studies; P = 0.25; very low-quality evidence).There was no difference between groups in change in FEV1 post-treatment (MD 0.01, 95% CI -0.03 to 0.05; 148 participants; 2 studies; P = 0.60; low-quality evidence). However, two trials reported improvement in exercise tolerance in the SSRI group versus the placebo group (MD 13.88, 95% CI 11.73 to 16.03; 148 participants; 2 studies; P < 0.001; very low-quality evidence).The trials included in this comparison did not report data related to the change in dyspnoea, hospital utilisation rates, or cost-effectiveness. AUTHORS' CONCLUSIONS There is insufficient evidence to make definitive statements about the efficacy or safety of antidepressants for treating COPD-related depression. New RCTs are needed; with better methodological quality and more accurate reporting of the methods used. Moreover, longer-term follow-up data collection is needed, including outcomes such as adverse events, hospital utilisation and cost-effectiveness.

Abstract
Background Depression is a major comorbidity in patients with chronic obstructive pulmonary disease (COPD). The aim of this prospective study was to investigate socio-demographic and clinical factors and serum markers of inflammation, including cytokines that, may be a cause or an association with COPD-related depression. Material/Methods This study enrolled 53 patients who were hospitalized in the Department of Respiratory Medicine of Hefei First People’s Hospital, China between October 2015 and October 2016. Patients were consecutively recruited who were diagnosed with COPD and without lower respiratory tract disease, psychiatric disorders, or a family history of cognitive disorders. All patients were investigated for symptoms of depression. Lung function testing included forced expiratory volume in 1 second (FEV1). Serum levels of C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-8 (IL-8) and tumor necrosis factor-α (TNF-α) were measured. Results Of the 53 patients with COPD, 40 (75.47%) patients had symptoms of depression. Univariate analysis showed that gender, smoking, a high level of education, duration of a cough, FEV1, and serum CRP level were associated with depression. A multivariate logistic regression model identified two risk factors for depression in patients with COPD: serum CRP level and FEV1. Conclusions The findings of this study showed that the risk factors for COPD-related depression included male gender, heavy smoking, higher academic qualifications, and duration of cough, but the two strongest risk factors were a high serum CRP level and low FEV1.

Abstract
Suicide is an important public health concern requiring ongoing research to understand risk factors for suicide ideation. A dual-frame, random digit dial survey was utilized to identify demographic and suicide-related factors associated with suicide ideation in a statewide sample of 1,736 adults. The PH-Q 9 Depression scale suicide ideation question was used to assess current suicide ideation in both the full sample and suicide exposed sub-sample. Being non-married and having previous suicide exposure were separately associated with higher risks of suicide ideation in the full sample. Being male, having increased suicide exposures, and having increased perceptions of closeness to the decedent increased risks, while older age decreased risks for the suicide exposed. Implications for future screening and research are discussed.
