Abstract
Studies on depression response to chronic pain are limited by lack of clarification of different forms of response patterns and cross-sectional measures. The current study examined heterogeneous long-term patterns of depression response to chronic pain onset prospectively using the mixture modeling technique. Depression symptoms prior to and following pain onset over a course of six years were charted in a nationally representative middle-aged sample. Four distinct depression symptom trajectories emerged. The resilience (72.0%) trajectory describes a pattern of no/minimal depression symptoms prior to and following pain onset. The post-pain depression trajectory (11.4%) describes a pattern of low depression at baseline and increasing symptoms following pain onset. The chronic depression (6.8%) trajectory is characterized by persistently high depression symptoms irrespective of pain onset. The prior depression improved (9.8%) trajectory describes a pattern of high depression at baseline and gradually declining symptoms following pain onset. Self-rated health at both baseline and following pain onset predicted the resilience trajectory. Baseline self-rated health distinguished the post-pain depression and chronic depression trajectories. Individuals in the prior depression improved trajectory were older and had more chronic illnesses at baseline but fewer illnesses following pain onset, compared to those in the resilience or post-pain depression trajectory.

Abstract
INTRODUCTION Depression and pain frequently occur together and impact on outcomes of existing treatment for depression. Additional treatment options are required. This study aimed to explore patients' experiences of depression, the processes of change within acupuncture and counselling, and the elements that contributed to longer-term change. METHODS In a substudy nested within a randomised controlled trial of acupuncture or counselling compared with usual care alone for depression, semistructured interviews of 52 purposively sampled participants were conducted and analysed using thematic analysis. RESULTS Differences were reported by participants regarding their experience of depression with comorbid pain compared with depression alone. Along with physical symptoms often related to fatigue and sleep, participants with depression and comorbid pain generally had fewer internal and external resources available to manage their depression effectively. Those who had physical symptoms and were receiving acupuncture commonly reported that these were addressed as part of the treatment. For those receiving counselling, there was less emphasis on physical symptoms and more on help with gaining an understanding of themselves and their situation. Over the course of treatment, most participants in both groups reported receiving support to cope with depression and pain independently of treatment, with a focus on relevant lifestyle and behaviour changes. The establishment of a therapeutic relationship and their active engagement as participants were identified as important components of treatment. CONCLUSIONS Participants with and without comorbid pain received acupuncture or counselling for depression, and reported specific identifiable treatment effects. The therapeutic relationship and participants' active engagement in recovery may play distinct roles in driving long-term change. Patients who present with depression and physical symptoms of care may wish to consider a short course of acupuncture to relieve symptoms prior to a referral for counselling if needed.

Chronic resveratrol treatment exerts antihyperalgesic effect and corrects co-morbid depressive like behaviors in mice with mononeuropathy: involvement of serotonergic system. Neuropharmacology 2014; 85:131-41. [PMID: 24835468 DOI: 10.1016/j.neuropharm.2014.04.021] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2014] [Revised: 04/24/2014] [Accepted: 04/29/2014] [Indexed: 12/16/2022]
Abstract
Patients suffering from chronic neuropathic pain are at high risk of co-morbid depression, which burdens healthcare. This work aimed to investigate the effects of resveratrol, a phenolic monomer enriched in red wine and grapes, on pain-related and depressive-like behaviors in mice with mononeuropathy, and explored the mechanism(s). Mice received chronic constriction injury (CCI) of sciatic nerves, and sequentially developed pain-related and depressive-like behaviors, as evidenced by sensory hypersensitivity (thermal hyperalgesia in Hargreaves test and mechanical allodynia in von Frey test) and behavioral despair (prolonged immobility time in forced swim test). Chronic treatment of neuropathic mice with resveratrol (30 mg/kg, p.o., twice per day for three weeks) normalized their thermal hyperalgesia (but not mechanical allodynia) and depressive-like behaviors, and these actions were abolished by chemical depletion of central serotonin (5-HT) but potentiated by co-treatment with 5-HTP, a precursor of 5-HT. The anti-hyperalgesia and anti-depression exerted by resveratrol may be pharmacologically segregated, since intrathecal (i.t.) and intracerebroventricular (i.c.v.) injection of methysergide, a non-selective 5-HT receptor antagonist, separately abrogated the two actions. Furthermore, the antihyperalgesic action of resveratrol was preferentially counteracted by co-administration of the 5-HT7 receptor antagonist SB-258719, while the anti-depression was abrogated by 5-HT1A receptor antagonist WAY-100635. These results confirm that chronic resveratrol administration exerts curative-like effects on thermal hyperalgesia and co-morbid depressive-like behaviors in mice with mononeuropathy. Spinal and supraspinal serotonergic systems (coupled with 5-HT7 and 5-HT1A receptors, respectively) are differentially responsible for the antihyperalgesic and antidepressant-like properties of resveratrol.

Abstract
BACKGROUND Depression with comorbid pain is associated with a poor response to various treatments. The objective in this secondary analysis was to determine whether patients reporting pain have different depression and pain outcomes over time in response to acupuncture, counselling or usual care. METHODS Self-reported ratings of depression and pain from 755 patients in a pragmatic randomised controlled trial of acupuncture (302) or counselling (302) compared to usual care alone (151) are described and analysed using a series of regression models and analysis of covariance. Patient-reported outcomes of Patient Health Questionnaire (PHQ)-9 for depression, SF36 bodily pain and EQ-5D, all at baseline, 3, 6, 9 and 12 months. RESULTS At baseline, 755 patients reported EQ-5D pain categories; 384 (50.9%) reported moderate-to-extreme pain. Controlling for baseline depression, a linear regression model showed that the presence of pain at baseline was associated with poorer depression outcomes at 3 months mean difference=-1.16, (95% CI 0.12 to 2.2). Participants with moderate-to-extreme pain at baseline did better at 3 months if they received acupuncture (mean reduction in Patient Health Questionnaire 9 (PHQ-9) from baseline=6.0, 95% CI 5.0 to 7.1 and a mean reduction in SF-36 bodily pain=11.2, (95% CI 7.1 to 15.2) compared to improvements for those who received counselling (4.3, 95% CI 3.3 to 5.4; 7.6, 95% CI 3.6 to 11.6) or usual care (2.7, 95% CI 1.50 to 4.0: 7.2, 95% CI 2.3 to 12.1). In comparison, no notable differences were seen between treatment arms within the no pain comparator group. CONCLUSIONS Patients with depression and pain at baseline recovered less well from treatment over 3 months than those with depression and no pain. Reductions in both depression and pain were most marked in the acupuncture group, followed by the counselling group and then the usual care group.

Chronic curcumin treatment normalizes depression-like behaviors in mice with mononeuropathy: involvement of supraspinal serotonergic system and GABAA receptor. Psychopharmacology (Berl) 2014; 231:2171-87.

Abstract
RATIONALE Comorbid depression is commonly observed in individuals who suffer from neuropathic pain, which necessitates improved treatment. Curcumin, a phenolic compound derived from Curcuma longa, possesses both antinociceptive and antidepressant-like activities in animal studies, suggesting its possible usefulness in treating this comorbidity. OBJECTIVE We investigated the effect of curcumin on depressive-like behaviors in mice with mononeuropathy, and explored the mechanism(s). METHODS Chronic constriction injury (CCI) was produced by loosely ligating the sciatic nerves in mice. The nociceptive behaviors were examined using Hargreaves test, and the depressive-like behaviors were determined by forced swim test (FST) and tail suspension test (TST). RESULTS After CCI injury, the neuropathic mice developed nociceptive and depressive-like behaviors, as shown by thermal hyperalgesia in Hargreaves test and protracted immobility time in FST and TST. Chronic treatment of neuropathic mice with curcumin (45 mg/kg, p.o., twice per day for 3 weeks) corrected their exacerbated nociceptive and depressive-like behaviors, which was abolished by chemical depletion of brain serotonin rather than noradrenaline. The paralleled antinociceptive and antidepressant-like actions of curcumin seem to be pharmacologically segregated, since intrathecal and intracerebroventricular injection of methysergide, a nonselective 5-HT receptor antagonist, separately counteracted the two actions of curcumin. Further, this antidepression was abrogated by repeated co-treatment with 5-HT1A receptor antagonist WAY-100635 and greatly attenuated by acute co-treatment with GABAA receptor antagonist bicuculline. CONCLUSION Curcumin can normalize the depressive-like behaviors of neuropathic mice, which may be independent of the concurrent analgesic action and possibly mediated via the supraspinal serotonergic system and downstream GABAA receptor.

Social support predicts inflammation, pain, and depressive symptoms: longitudinal relationships among breast cancer survivors. Psychoneuroendocrinology 2014; 42:38-44.

Abstract
OBJECTIVE Pain and depressive symptoms are commonly experienced by cancer survivors. Lower social support is linked to a variety of negative mental and physical health outcomes among survivors. Immune dysregulation may be one mechanism linking low social support to the development of pain and depressive symptoms over time. Accordingly, the goal of the present study was to examine the relationships among survivors' social support, pain, depressive symptoms, and inflammation. METHODS Breast cancer survivors (N=164, stages 0-IIIA) completed two study visits, one before any cancer treatment and the other 6 months after the completion of surgery, radiation, or chemotherapy, whichever came last. Women completed self-report questionnaires assessing social support, pain, and depressive symptoms, and provided a blood sample at both visits. RESULTS Survivors with lower social support prior to treatment experienced higher levels of pain and depressive symptoms over time than their more socially supported counterparts. Furthermore, women with lower pretreatment social support had higher levels of IL-6 over time, and these elevations in IL-6 predicted marginally larger increases in depressive symptoms. CONCLUSIONS The results of this study suggest that social support at the time of diagnosis predicts the post-treatment development of pain, depressive symptoms, and inflammation. Consequently, early interventions targeting survivors' social networks could improve quality of life during survivorship.

Abstract
OBJECTIVE This study examined prospectively the effect of workplace violence on musculoskeletal symptoms among nursing home workers. BACKGROUND Previously we reported a cross-sectional relationship between physical assaults at work and musculoskeletal pain. This follow-up provides stronger evidence of the effect of workplace violence on musculoskeletal outcomes within the same workforce over two years. METHOD Nursing home workers who responded to three consecutive annual surveys formed the study cohort (n = 344). The outcomes were any musculoskeletal pain, widespread pain, pain intensity, pain interference with work and sleep, and co-occurring pain with depression. The main predictor was self-reported physical assault at work during the 3 months preceding each survey. Prevalence ratios (PRs) were assessed with log-binomial regression, adjusting for other workplace and individual factors. RESULTS Every fourth nursing home worker, and 34% of nursing aides, reported persistent workplace assault over the 2 years. Among respondents assaulted frequently, two thirds experienced moderate to extreme musculoskeletal pain, and more than 50% had pain interfering with work and/or sleep. Baseline exposure to assault predicted pain outcomes 1 year later. Repeated exposure was associated with a linear increase over 2 years in the risks of pain intensity, interference with work, and interference with sleep; co-occurring pain and depression had an adjusted PR of 3.6 (95% CI = 1.7-7.9). CONCLUSION Workplace assault, especially when repeated over time, increases the risk of pain that may jeopardize workers' ability to remain employed. APPLICATION More effective assault prevention would protect and support the workforce needed to care for our increasing elderly and disabled population.

Abstract
OBJECTIVE Dysphagia--difficulty eating and swallowing--can significantly impair a patient's ability to maintain adequate nutritional and medication intake. There are a large number of patients with chronic pain, including pediatric, geriatric, and palliative care patients, who suffer from dysphagia and, therefore, have difficulty achieving optimal pain management with solid, oral formulations. The objective of this study was to survey physicians and patients in the US to understand their knowledge, attitudes, and clinical management/analgesic usage patterns in the treatment of patients with chronic pain with dysphagia (CPD). RESEARCH DESIGN AND METHODS Two separate surveys were administered to physicians and patients. The physician survey design was qualitative; physicians participated in a semi-structured phone interview. The patient survey design was quantitative; patients participated in a structured online survey. Purposive sampling was used to recruit participants into both studies. Physician participants were identified based on their specialty, prescribing practices, and geographic location. Patient participants were recruited through a consumer panel of pre-identified individuals who, for 3 months or longer, had chronic pain and were taking opioids. RESULTS Thirty-four physicians and 1021 patients were surveyed. Physicians indicated that 5-20% of their patients had difficulty swallowing. Treatment for CPD consisted of the fentanyl patch, immediate-release opioids, methadone liquid, or extended-release morphine products. Physicians were not satisfied with currently available treatment options. Twenty-nine per cent of patients surveyed had trouble swallowing or disliked swallowing pills. Eighty per cent of patients were not asked about their ability to swallow solid, oral dosage forms by their physician. To circumvent swallowing difficulties, some patients (16%) cut/crush/grind their medication to facilitate swallowing. Most of these patients (65%) did not know that altering tablets could potentially change the drug release (pharmacokinetic) characteristics of the tablet and lead to serious adverse events. LIMITATIONS Qualitative survey research can be influenced by responder bias as well as selection bias. The number of survey participants for both the physician and patient surveys was small, thus responses may not reflect those in the general population. CONCLUSION A proportion of patients with chronic pain have dysphagia and cannot swallow solid, oral dosage forms, which creates a serious treatment challenge for pain specialists and other healthcare providers. Currently available treatment options have limitations; new treatment options would be welcomed by both physicians and patients. Physician and patient education should be enhanced in order to promote awareness of the deleterious consequences associated with altering currently available analgesic formulations. Facilitating patient-physician communication on this topic may help to improve treatment outcomes.

Abstract
Clinically, it is suggested that chronic pain might induce mood disorders like depression and anxiety. Based on this antidepressant drugs have emerged as a new therapy for pain. In this study, the effect of acute and subchronic treatments with 3-(4-fluorophenylselenyl)-2,5-diphenylselenophene (F-DPS) on behavioral changes induced by partial sciatic nerve ligation (PSNL) was evaluated. At the 4th week after surgery, PSNL caused a significant depression-like behavior in mice evaluated in the forced swimming test (FST) and the tail suspension test (TST), which was accompanied by increased pain sensitivity. The anxiety-like behavior assessed in the light-dark test (LDT) was not modified by PSNL. Acute treatment with F-DPS, at a dose of 1 mg/kg, intragastrically (i.g.) administered 30 min before the FST, produced a significant anti-immobility effect in PSNL mice. The antidepressant drug paroxetine showed acute antidepressant-like action at a dose 10 times higher than F-DPS. Subchronic treatment with F-DPS (0.1 mg/kg, i.g.) reversed depression-like behavior of sciatic nerve-ligated mice in the TST and FST and produced a significant anxiolytic-like action in both sham-operated and PSNL animals. Although the acute F-DPS treatment did not produce anti-allodynic effect, F-DPS subchronic treatment significantly reduced pain sensitivity in PSNL mice. These findings demonstrated that F-DPS blocked behavioral changes induced by neuropathic pain, suggesting that it might be attractive in the pharmacological approach of pain-emotion diseases.

Abstract
The intensity and severity of perceived pain does not correlate consistently with the degree of peripheral or central nervous system tissue damage or with the intensity of primary afferent or spinal nociceptive neurone activity. In this respect, the modulation of pain by emotion and context is now widely recognized. In particular, stress, fear and anxiety exert potent, but complex, modulatory influences on pain. Stress can either suppress pain (stress-induced analgesia) or exacerbate it (stress-induced hyperalgesia; SIH) depending on the nature, duration and intensity of the stressor. Herein, we review the methods and models used to study the phenomenon of SIH in rodents and humans and then present a detailed discussion of our current understanding of neural substrates and neurobiological mechanisms. The review provides perspectives and challenges for the current and future treatment of pain and the co-morbidity of pain with stress-related psychiatric disorders including anxiety and depression.

Abstract
OBJECTIVE To compare the efficacy of duloxetine with placebo on depression in elderly patients with major depressive disorder. DESIGN Multicenter, 24-week (12-week short-term and 12-week continuation), randomized, placebo-controlled, double-blind trial. SETTING United States, France, Mexico, Puerto Rico. PARTICIPANTS Age 65 years or more with major depressive disorder diagnosis (one or more previous episode); Mini-Mental State Examination score ≥20; Montgomery-Asberg Depression Rating Scale total score ≥20. INTERVENTION Duloxetine 60 or 120 mg/day or placebo; placebo rescue possible. MEASUREMENTS Primary-Maier subscale of the 17-item Hamilton Depression Rating Scale (HAMD-17) at week 12. Secondary-Geriatric Depression Scale, HAMD-17 total score, cognitive measures, Brief Pain Inventory (BPI), Numeric Rating Scales (NRS) for pain, Clinical Global Impression-Severity scale, Patient Global Impression of Improvement in acute phase and acute plus continuation phase of treatment. RESULTS Compared with placebo, duloxetine did not show significantly greater improvement from baseline on Maier subscale at 12 weeks, but did show significantly greater improvement at weeks 4, 8, 16, and 20. Similar patterns for Geriatric Depression Scale and Clinical Global Impression-Severity scale emerged, with significance also seen at week 24. There was a significant treatment effect for all BPI items and 4 of 6 NRS pain measures in the acute phase, most BPI items and half of the NRS measures in the continuation phase. More duloxetine-treated patients completed the study (63% versus 55%). A significantly higher percentage of duloxetine-treated patients versus placebo discontinued due to adverse event (15.3% versus 5.8%). CONCLUSIONS Although the antidepressant efficacy of duloxetine was not confirmed by the primary outcome, several secondary measures at multiple time points suggested efficacy. Duloxetine had significant and meaningful beneficial effects on pain.

Abstract
Comorbid depression and chronic pain are highly prevalent in individuals suffering from physical illness. Here, we critically examine the possibility that inflammation is the common mediator of this comorbidity, and we explore the implications of this hypothesis. Inflammation signals the brain to induce sickness responses that include increased pain and negative affect. This is a typical and adaptive response to acute inflammation. However, chronic inflammation induces a transition from these typical sickness behaviors into depression and chronic pain. Several mechanisms can account for the high comorbidity of pain and depression that stem from the precipitating inflammation in physically ill patients. These mechanisms include direct effects of cytokines on the neuronal environment or indirect effects via downregulation of G protein-coupled receptor kinase 2, activation of the tryptophan-degrading enzyme indoleamine 2,3-dioxygenase that generates neurotropic kynurenine metabolites, increased brain extracellular glutamate, and the switch of GABAergic neurotransmission from inhibition to excitation. Despite the existence of many neuroimmune candidate mechanisms for the co-occurrence of depression and chronic pain, little work has been devoted so far to critically assess their mediating role in these comorbid symptoms. Understanding neuroimmune mechanisms that underlie depression and pain comorbidity may yield effective pharmaceutical targets that can treat both conditions simultaneously beyond traditional antidepressants and analgesics.

Abstract
INTRODUCTION An apparent clinical relationship between pain and depression has long been recognized, which makes an enormous impact on the individual health care. At present, the practical implication of such overlapping symptomatology between pain and depression is not clear, but the prevalence estimates for depression are substantially inflated among patients with chronic pain and vice versa. This interaction has been labeled as the depression-pain syndrome or depression-pain dyad. AREAS COVERED This article discusses the neurobiological substrates and neuroanatomical pathways involved in pain-depression dyad along with newer therapeutic targets. EXPERT OPINION Several key themes emerged from our review of the relationship between depression and pain. First, the diagnosis of depression in pain or vice versa is particularly challenging, and the development of better diagnostic framework that involves both pain and depression is particularly required. Secondly, the entwined relationship between pain and depression supports the possibility of common coactivating factors that results in their neurophysiological overlap. A broad understanding of the role played by the central nervous system (CNS) in the processing of pain and depression may eventually lead to the introduction of triple reuptake inhibitors, agomelatine, vilazodone and ketamine with novel mechanism of action, hence appear to be of promising potential for pain with depression.

Possible involvement of oxido-nitrosative stress induced neuro-inflammatory cascade and monoaminergic pathway: underpinning the correlation between nociceptive and depressive behaviour in a rodent model. J Affect Disord 2013; 151:1041-52.

Abstract
BACKGROUND Pain and depression are frequent co-morbid disorders. The prevalence rate of depression is several times higher in patients with chronic pain than in the general population but the mechanism underlying this association is unknown. A combination of interactions between neurotransmitters, neuropeptides, oxidative and nitrosative stress and cytokines are thought to take part in pathogenesis of pain as well as depression. Thus, the aim of the present study was two-fold, first to investigate the interplay between nociception and associated depression and second to investigate the protective potential of berberine against the reserpine-induced nociceptive and depressive behaviour and further to explore the role of oxidative-nitrosative stress mediated inflammatory cascade and apoptotic signalling pathway in this dyad. METHODS AND RESULTS Nociception and associated depression were induced by administration of reserpine (1mg/kg subcutaneous daily) for three consecutive days. This behavioural deficit was integrated with decrease in the biogenic amine (dopamine, norepinephrine and serotonin) levels along with increased substance P concentration, oxidative-nitrosative stress, inflammatory cytokines, NF-κβ and caspase-3 levels in different brain regions (cortex and hippocampus) of the reserpinised rats. LIMITATION More studies are still warranted in similar rodent models of pain and depression, so, that the present findings can be further substantiated to establish the clinical effectiveness of berberine in a subset of patients suffering from pain as well as depression. CONCLUSION The findings from the current study suggested that reserpine-induced neurochemical alterations and dysregulation of oxidative-nitrosative stress induced inflammatory cascade underlies the co-morbidity of nociceptive behaviour and associated depression in rats.

Abstract
The comorbidity of pain and depression has been well established in the literature and is associated with a greater burden to the individual and society than either condition alone. The relationship between pain and depression is quite complex and multiple factors must be considered when trying to disentangle the pain-depression link including shared neurobiology, precipitating environmental factors and cognitive influences. This article aims to provide an overview of the leading neurobiological and psychosocial theories that have advanced our understanding of the link between pain and depression. To this end we describe the shared neurobiological mechanisms in the brain thought to explain the overlap and consider psychological processes and how they inform a cognitive behavioral model. The article also provides an overview of the evidence based treatment for comorbid pain and depression.

Abstract
OBJECTIVE The long-term effects of disease and treatment in colorectal cancer (CRC) survivors are poorly understood. This study examined the prevalence and characteristics of pain in a sample of CRC survivors up to 10 years post-treatment. DESIGN One hundred cancer-free CRC survivors were randomly chosen from an institutional database and completed a telephone survey using the Brief Pain Inventory, Neuropathic Pain Questionnaire-Short Form, Quality of Life Cancer Survivor Summary, Brief Zung Self-Rating Depression Scale, Zung Self-Rating Anxiety Scale, and Fear of Recurrence Questionnaire. RESULTS Participants were primarily Caucasian (90%) married (69%) males (53.5%) with a mean age of 64.7 years. Chronic pain was reported in 23% of CRC survivors, with a mean moderate intensity rating (mean = 6.05, standard deviation = 2.66) on a 0-10 rating scale. Over one-third (39%) of those with pain attributed it to their cancer or treatment. Chi-square and t-test analyses showed that survivors with pain were more likely to be female, have lower income, be more depressed and more anxious, and show a higher endorsement of suicidal ideation than CRC survivors without chronic pain. On average, pain moderately interfered with daily activity. CONCLUSIONS Chronic pain is likely a burdensome problem for a small but not inconsequential minority of CRC survivors requiring a biopsychosocial treatment approach to improve recognition and treatment. Open dialogue between clinicians and survivors about physical and emotional symptoms in long-term follow-up is highly recommended.

Abstract
BACKGROUND Little is known about depression in older people in sub-Saharan Africa, the associated impact of HIV, and the influence on health perceptions. OBJECTIVES Examine the prevalence and correlates of depression; explore the relationship between depression and health perceptions in HIV-infected and -affected older people. METHODS In 2010, 422 HIV-infected and -affected participants aged 50+ were recruited into a cross-sectional study. Nurse professionals interviewed participants and a diagnosis of depressive episode was derived from the Composite International Diagnostic Interview (Depression module) using the International Classification of Diseases diagnostic criteria and categorised as major (MDE) or brief (BDE). RESULTS Overall, 42.4% (n=179) had a depressive episode (MDE: 22.7%, n=96; BDE: 19.7%, n=83). Prevalence of MDE was significantly higher in HIV-affected (30.1%, 95% CI 24.0-36.2%) than HIV-infected (14.8%, 95% CI 9.9-19.7%) participants; BDE was higher in HIV-infected (24.6%, 95% CI 18.7-30.6%) than in HIV-affected (15.1%, 95% CI 10.3-19.8%) participants. Being female (aOR 3.04, 95% CI 1.73-5.36), receiving a government grant (aOR 0.34, 95% CI 0.15-0.75), urban residency (aOR 1.86, 95% CI 1.16-2.96) and adult care-giving (aOR 2.37, 95% CI 1.37-4.12) were significantly associated with any depressive episode. Participants with a depressive episode were 2-3 times more likely to report poor health perceptions. LIMITATIONS Study limitations include the cross-sectional design, limited sample size and possible selection biases. CONCLUSIONS Prevalence of depressive episodes was high. Major depressive episodes were higher in HIV-affected than HIV-infected participants. Psycho-social support similar to that of HIV treatment programmes around HIV-affected older people may be useful in reducing their vulnerability to depression.

Abstract
Objectives Although efficacious treatments for mood disorders are available in primary care, under-diagnosis is associated with under-treatment and poorer outcomes. This study compares the accuracy of self-administered screening tests with routine general practitioner (GP) assessment for detection of current mood disorder. Methods 197 consecutive patients attending primary care centres in Santiago, Chile enrolled in this cross-sectional study, filling out the Patients Health Questionnaire-9 (PHQ-9) for depression and the Mood Disorder Questionnaire (MDQ) for bipolar disorder, after routine GP assessment. Diagnostic accuracy of these self-administered tools was compared with GP assessment, with gold standard diagnosis established by a structured diagnostic interview with trained clinicians (SCID-I). Results The sample was 75% female, with a mean age of 48.5 (SD 16.8); 37% had a current mood disorder (positive SCID-I result for depression or bipolar disorder). Sensitivity of the screening instruments (SI) was substantially higher than GP assessment (SI: 0.8, [95% CI 0.71, 0.81], versus GP: 0.2, [95% CI 0.12, 0.25]: p-value < 0.0001), without sacrifice in specificity (SI: 0.9, [95% CI 0.86, 0.96], versus GP: 0.9, [95% CI 0.88, 0.97]: p-value = 0.7). This led to improvement in both positive predictive value (SI: 0.8, [95% CI 0.82, 0.90], versus GP: 0.6, [95% CI 0.50, 0.64]: p-value < 0.001) and negative predictive value (SI: 0.9, [95% CI 0.78, 0.91] versus GP: 0.7, [95% CI 0.56, 0.72]: p-value < 0.01). Conclusion Self-administered screening tools are more accurate than GP assessment in detecting current mood disorder in low-income primary care. Such screening tests may improve detection of current mood disorder if implemented in primary care settings.

Abstract
Although chronic pain affects all age ranges, it is particularly common in the elderly. One potential explanation for the high prevalence of chronic pain in the older population is impaired functioning of the descending pain inhibitory system which can be studied in humans using conditioned pain modulation (CPM) paradigms. In this study we investigated (i) the influence of age on CPM and (ii) the role of expectations, depression and gender as potential modulating variables of an age-related change in CPM. 64 healthy volunteers of three different age groups (young = 20–40 years, middle-aged = 41–60 years, old = 61–80 years) were studied using a classical CPM paradigm that combined moderate heat pain stimuli to the right forearm as test stimuli (TS) and immersion of the contralateral foot into ice water as the conditioning stimulus (CS). The CPM response showed an age-dependent decline with strong CPM responses in young adults but no significant CPM responses in middle-aged and older adults. These age-related changes in CPM responses could not be explained by expectations of pain relief or depression. Furthermore, changes in CPM responses did not differ between men and women. Our results strongly support the notion of a genuine deterioration of descending pain inhibitory mechanisms with age.

Abstract
BACKGROUND The comorbidity of pain and depression is associated with high disease burden for patients in terms of disability, wellbeing, and use of medical care. Patients with major and minor depression often present themselves with pain to a general practitioner and recognition of depression in such cases is low, but evolving. Also, physical symptoms, including pain, in major depressive disorder, predict a poorer response to treatment. A multi-faceted, patient-tailored treatment programme, like collaborative care, is promising. However, treatment of chronic pain conditions in depressive patients has, so far, received limited attention in research. Cost effectiveness of an integrated approach of pain in depressed patients has not been studied. METHODS/DESIGN This study is a placebo controlled double blind, three armed randomized multi centre trial. Patients with (sub)chronic pain and a depressive disorder are randomized to either a) collaborative care with duloxetine, b) collaborative care with placebo or c) duloxetine alone. 189 completers are needed to attain sufficient power to show a clinically significant effect of 0.6 SD on the primary outcome measures (PHQ-9 score). Data on depression, anxiety, mental and physical health, medication adherence, medication tolerability, quality of life, patient-doctor relationship, coping, health resource use and productivity will be collected at baseline and after three, six, nine and twelve months. DISCUSSION This study enables us to show the value of a closely monitored integrated treatment model above usual pharmacological treatment. Furthermore, a comparison with a placebo arm enables us to evaluate effectiveness of duloxetine in this population in a real life setting. Also, this study will provide evidence-based treatments and tools for their implementation in practice. This will facilitate generalization and implementation of results of this study. Moreover, patients included in this study are screened for pain symptoms, differentiating between nociceptive and neuropathic pain. Therefore, pain relief can be thoroughly evaluated.

OBJECTIVE The aim of the present study was to assess the prevalence of alexithymia in a sample of general chronic pain patients, to explore possible differences in depression and pain variables between alexithymic and nonalexithymic chronic pain patients and to analyze if depression is a mediator between alexithymia and pain disability. METHODS Two hundred and seventy-one patients making their first visit to a pain clinic completed the study questionnaire including various pain measures, the Beck Depression Inventory-II (BDI-II) and the 20-item Toronto Alexithymia Scale (TAS-20). The sample was dichotomized to alexithymic and nonalexithymic groups. The means of the study variables were compared between the groups. The correlation analysis of the variables was carried out separately in both groups. Path analysis was done to ascertain the mediation effect of BDI-II between the TAS-20 and pain disability. RESULTS Every fifth chronic pain patient was alexithymic. The BDI-II and pain variable scores were significantly higher in the alexithymic group than in the nonalexithymic group. Pain variables were not associated with alexithymia when BDI-II was controlled for. BDI-II worked as a full mediator between TAS-20 and pain disability. CONCLUSION The alexithymic patient group was more morbid than the nonalexithymic group. The results suggest that depression is the main factor in pain conditions of alexithymic chronic pain patients. The authors recommend screening and treatment of depression in alexithymic chronic pain patients.

Abstract
Background: Presence of major depressive syndrome (MDS) in chronic pain patients (CPPs) requires more attention from the clinicians because of its clinical nature, association of suicidal thoughts and their actual completion, and treatment difficulties. The prevalence of MDS among Indian CPPs is not well studied. Aim: To determine the prevalence of MDS among Indian CPPs visiting pain clinic. Materials and Methods: In this prospective study, 476 patients who attended a pain clinic in a metropolitan city of India for chronic pain (pain more than six months) were included. They were assessed by ‘PHQ-9 depression scale’ for presence of MDS. Intensity of pain was assessed by ‘Visual analogue scale’ (VAS). Patient details (viz. age, sex), duration and site of pain, and scores of PHQ-9 depression scale and VAS, were noted and statistically analyzed. Results: 146 out of 476 CPPs (30.67%) were found to suffer from MDS. Women were more prone (F: M =3:2) to develop MDS while suffering from chronic pain. Among 146 CPPs who were suffering from MDS, 108 (73.97%) patients also had suicidal thought. The prevalence of suicidal thought among all CPPs was found to be 22.69%. The depression severity was found to be strongly associated with intensity of pain (P = 0.005 < 0.05) but not associated with the duration of pain (P = 0.159 > 0.05) and age of the patient (P = 0.24 > 0.05). Conclusion: We found a high prevalence of MDS among CPPs from India and majority of them also harbored suicidal thought. Therefore, for successful outcome in chronic pain management routine psychological assessment in CPPs should be done to exclude the presence of MDS and suicidal thought.

Abstract
BACKGROUND Mental ill-health and pain are major causes for disability compensation in female adults in Sweden. Aims The aims of this study were to (1) analyse gender differences in the prevalence of depression among immigrant patients with chronic back pain and (2) explore whether factors such as age, marital status, educational level, religious faith, number of children and number of diagnosed pain sites could explain these differences. METHODS The study sample consisted of 245 sick-listed primary care patients in consecutive order aged 18 through 45 years with a median duration of sick leave of 10 months for back pain and participating in a rehabilitation programme. Explanatory variables included physicians' diagnosed pain sites, age, marital status, education, number of children and religious affiliation. Predictive factors for depression were analysed using logistic regression. FINDINGS The women differed significantly from the men in three aspects: they were less educated, had more children and had more multiple pain sites, that is, 68% versus 45%. In the age-adjusted model, women were twice as likely to have depression (odds ratio (OR) 2.1). Regardless the gender, those with intermediate education of 9-11 years had the lowest odds of outcome compared with those with <0-8 years and ⩾12 years education. Finally, after adjusting for all explanatory variables, the ORs of depression for women decreased to a non-significant level (OR 1.8; 95% confidence interval (CI) 0.94-3.43). Furthermore, regardless of the gender, those with multiple pain sites had twice higher odds (OR 2.04; 95% CI 1.11-3.74) of depression than those with fewer pain sites. CONCLUSION Gender differences in odds of depression in our study could be explained by a higher prevalence of diagnosed multiple pain sites in women. This calls for tailor-made treatments that focus on the pain relief needs of immigrant women with low education and chronic back pain.

Abstract
Late-life depression is common among nursing home residents, but often is not addressed by nurses. Using a self-directed CD-based depression training program, this pilot study used mixed methods to assess feasibility issues, determine nurse perceptions of training, and evaluate depression-related outcomes among residents in usual care and training conditions. Of 58 nurses enrolled, 24 completed the training and gave it high ratings. Outcomes for 50 residents include statistically significant reductions in depression severity over time (p < 0.001) among all groups. Depression training is an important vehicle to improve depression recognition and daily nursing care, but diverse factors must be addressed to assure optimal outcomes.

Abstract
The treatment for pain in emergency medicine is a matter of increasing interest. Available data indicate that in both normal conditions and during major-emergencies, the majority of healthcare providers are culturally and professionally unprepared to adequately treat acute pain conditions. In case of natural disasters, opioid drugs are often unavailable. Moreover, no guidelines or validated protocols provide adequate indications for the treatment for pain in case of massive emergencies. Training of the medical and nursing staff, in both formal and continuing, or on-the-job education is needed to adequately face a devastating emergency. Unfortunately, there is an inadequate level of training among healthcare professionals, even in highly seismic areas, and the source of aid is frequently limited, especially in the immediate aftermath of a disaster to those already present at the scene. Pain inadequately treated may modify the characteristics of the pain itself. Pain is no longer considered just a symptom, but itself becomes an autonomous pathology heavily influencing the social life and psycho-social aspects of a person. In the disastrous situation following an earthquake, an inadequate treatment of pain was the major violation of the psycho-physical integrity of individuals and a severe violation of their rights, as human beings and patients.

Abstract
OBJECTIVES There is a strong association between depression and pain, which is influenced by various biological and psychological mechanisms. The objectives of this study were to assess the prevalence and severity of pain symptoms among patients with major depression; and to determine the correlation between pain with clinical variables, neurotic pathology and severity of depression. METHODS Fifty-one Malay patients with major depressive disorder without psychotic feature enrolled for the study. They were assessed with the Hamilton Rating Scale for Depression (HAM-D), Brief Pain Inventory (BPI) and Crown Crisp Experiential Index (CCEI). RESULTS The majority (80.4%) of the subjects had experienced pain, but overall severity of the pain was mild (33.3%). There were no statistically significant differences in socio-demographic variables with the status of pain. The prevalence of pain was significantly higher in patients who were still depressed (p<0.05), had anxious depression (p<0.05) and those with prominent somatic symptoms of anxiety (SOM) (p<0.05). The severity of pain was significantly correlated with neuroticism, the severity of depression (HAM-D total score) and high scores on SOM, DEP and FFA subscales of the CCEI. Among the three, the DEP subscale had the highest correlation with severity of pain. CONCLUSIONS The somatising patients were heterogeneous group. The pain symptoms were common in severe mixed anxiety-depression, predisposed by the underlying neurotic pathology. Neuroticism and high scores on SOM, DEP and FFA subscales of the CCEI contributed significantly to the pathogenesis of depressed Malay patients with pain symptoms.

Abstract
A connection between pain and depression has long been recognized in the clinical setting; however, its mechanism remains unclear. This study showed that mechanical hyperalgesia induced by unilateral temporomandibular joint (TMJ) inflammation was exacerbated in Wistar-Kyoto (WKY) rats with genetically predisposed depressive behavior. Reciprocally, TMJ inflammation enhanced depressive behavior such that a lower nociceptive threshold correlated with a higher score of depressive behavior in the same WKY rats. As compared with Wistar rats, WKY rats showed a lower plasma melatonin level, downregulation of the melatonin MT1 receptor, but upregulation of the NR1 subunit of the NMDA receptor in the ipsilateral trigeminal subnucleus caudalis (Sp5C). Intracisternal administration of 6-chloromelatonin (250 μg, twice daily for 7 days) concurrently attenuated mechanical hyperalgesia and depressive behavior in WKY rats as well as downregulated the NR1 expression in the ipsilateral Sp5C. In patch-clamp recordings, melatonin dose-dependently decreased NMDA-induced currents in spinal cord dorsal horn substantia gelatinosa neurons. These results demonstrate a reciprocal relationship between TMJ inflammation-induced mechanical hyperalgesia and depressive behavior and suggest that the central melatoninergic system, through modulation of the NMDA receptor expression and activity, may play a role in the mechanisms of the comorbidity between pain and depression.

Abstract
This study of 2,163 adult chronic, non-cancer-pain, long-term opioid therapy patients examines the relationship of depression to functional disability by measuring average pain interference, activity limitation days, and employment status. Those with more depression symptoms compared to those with fewer were more likely to have worse disability on all 3 measures (average pain interference score >5, OR = 5.36, p < .0001; activity limitation days ≥ 30, OR = 4.05, p < .0001; unemployed due to health reasons, OR = 4.06, p < .0001). Depression might play a crucial role in the lives of these patients; identifying and treating depression symptoms in chronic pain patients should be a priority.

Abstract
OBJECTIVE To investigate the relationship between the characteristics of somatic symptoms and depression severity, quality of life (QOL), and health resources utilization in patients with major depressive disorder (MDD) in primary care setting. METHOD This cross-sectional, nationwide epidemiologic study, carried out in 1150 primary care patients with DSM-IV-defined MDD, evaluated the characteristics of somatic symptoms by means of the Standardized Polyvalent Psychiatric Interview. Depression severity and QOL were evaluated by means of the Zung Self-Rating Depression Scale (SDS) and the Physical and Mental Component Summaries of the Medical Outcomes Study 12-item Short-Form Health Survey. Health resources utilization was measured in terms of doctor consultations and hospitalizations. The associations were assessed by means of adjusted analyses. The study was carried out from April 2004 to July 2004. RESULTS Disability associated with somatic symptoms and number of somatic symptoms were strongly associated with increased depression severity (2.45 and 0.29 increase in SDS score, respectively) and health resources utilization (odds ratios of 1.42 and 1.04, respectively). Associated disability, frequency, and persistence during leisure time of somatic symptoms were strongly associated with poorer QOL. In contrast, we found a weaker relationship between duration and intensity of somatic symptoms and depression severity, QOL, and health resources utilization. CONCLUSIONS Of the studied somatic symptom characteristics, somatic symptom-associated disability and number of somatic symptoms are strongly associated with increased depression severity and health resources utilization, as well as with decreased QOL. Our results may help physicians identify relevant characteristics of somatic symptoms to more effectively diagnose and treat depression in primary care patients.

Abstract
OBJECTIVE We examined chronic pain management practices and confidence and satisfaction levels in treating chronic pain among primary care providers (PCPs) who cared for high-risk patients in safety net health settings. DESIGN We recruited PCPs (N = 61) through their HIV-infected patients who were enrolled in a longitudinal study on pain, use, and misuse of opioid analgesics (Pain Study). We asked PCPs to complete a questionnaire about all of their patients in their practice on the prevalence of chronic pain and illicit substance use, use of opioid analgesics, confidence and satisfaction levels in treating chronic pain, and likelihood of prescribing opioid analgesics in response to clinical vignettes. RESULTS All PCPs cared for at least some patients with chronic pain, and the majority prescribed opioid analgesics for its treatment. All PCPs cared for at least some patients who used illicit substances. PCPs reported low confidence and satisfaction levels in treating chronic pain. The majority (73.8%) of PCPs were highly likely to prescribe opioid analgesics to a patient without a history of substance use who had chronic pain. The majority (88.5%) were somewhat to highly likely to prescribe opioid analgesics to a patient with a prior history of substance use but not active use. Most (67.2%) were somewhat to highly likely to prescribe opioids to a patient with active substance use. CONCLUSION In order to improve PCPs' confidence and satisfaction in managing chronic pain, further work should explore the root causes of low confidence and satisfaction and also explore possible remedies.

Abstract
BACKGROUND Population ageing is a worldwide phenomenon that has recently challenged public healthcare systems. The knowledge of the burden of chronic musculoskeletal disorders in elders is still limited, particularly in the developing world. This systematic review aimed to investigate the prevalence of chronic musculoskeletal disorders in elderly Brazilians. METHODS A comprehensive literature search was performed in five electronic databases (from inception to January 2012) and completed by additional searches in reference lists. Two review authors independently selected the eligible studies and extracted data on participants' characteristics and rates of chronic musculoskeletal disorders. One review author extracted methodological quality data. We performed a critical synthesis of the results, which were grouped into the diagnoses "chronic musculoskeletal pain" or "specific musculoskeletal diagnoses". RESULTS Twenty five studies reporting on a total of 116,091 elderly Brazilians were included. Eight studies (32%) were of high methodological quality. There was a large variation in the measure of prevalence used by individual studies and in their definition of chronic pain. Prevalence estimates reached 86% for chronic musculoskeletal pain in any location. Studies investigating multiple pain sites found the lower limb and the spine to be the most prevalent complaints (50% each). Arthritis and rheumatism (including osteoarthritis) were the most prevalent specific musculoskeletal diagnoses (9% to 40%), followed by herniated disc (6% to 27%). CONCLUSIONS Despite the growth of the elderly population worldwide, high-quality research on the burden of chronic musculoskeletal disorders in the elderly is still scarce. Future healthcare research focusing on this age group should be a priority in developing countries since their public healthcare systems are not yet fully prepared to accommodate the needs of an aging population.

Abstract
BACKGROUND Previous animal studies have illustrated a modulatory effect of neonatal pain experience on subsequent pain-related behaviors. However, the relationship between chronic pain status in adulthood and future pain perception remains unclear. METHODOLOGY/PRINCIPAL FINDINGS In the current study, we investigated the effects of inflammatory pain experience on subsequent formalin-evoked pain behaviors and fear conditioning induced by noxious stimulation in adult rats. Our results demonstrated an increase of the second but not the first phase of formalin-induced pain behaviors in animals with a history of inflammatory pain that have recovered. Similarly, rats with persistent pain experience displayed facilitated acquisition and prolonged retention of pain-related conditioning. These effects of prior pain experience on subsequent behavior were prevented by repeated morphine administration at an early stage of inflammatory pain. CONCLUSIONS/SIGNIFICANCE These results suggest that chronic pain diseases, if not properly and promptly treated, may have a long-lasting impact on processing and perception of environmental threats. This may increase the susceptibility of patients to subsequent pain-related disorders, even when chronic pain develops in adulthood. These data highlight the importance of treatment of chronic pain at an early stage.

Abstract
We examined the relative impact of baseline anxiety, depression and fear of movement on health related quality of life at 12-month follow-up after a multidisciplinary pain management programme. One hundred and eleven patients who had chronic musculoskeletal pain (mean age 45 years, 65% women) attended during 2003–2005 a multidisciplinary three-phase pain management programme with a total time frame of six to seven months, totalling 19 days. The Beck Anxiety Inventory was used to rate anxiety, the Beck Depression Inventory depression, the Tampa Scale of Kinesiophobia fear of movement. The generic 15D questionnaire was used to assess health related quality of life. Baseline data were collected at admission, follow-up data at 12 months. Mean health related quality of life increased significantly from baseline to 12-month follow-up. Anxiety at baseline predicted significant negative change in the health related quality of life, depression predicted significant positive change in the health related quality of life. Fear of movement did not predict any significant change in the health related quality of life. We concluded that patients with chronic musculoskeletal pain and mild to moderate depression benefit from a multidisciplinary pain management programme in contrast to anxious patients. The findings imply further research with bigger sample sizes, other than HRQoL outcome measures as well as with other groups of patients.

Abstract
We describe a new term: glutamate-based depression (GBD). GBD is defined as a chronic depressive illness associated with environmental stress and diseases associated with altered glutamate neurotransmission. We hypothesize that glutamate-induced over-activation of extrasynaptic NMDA receptors in the subgenual cingulate area called Brodmann's 25 plays an important role in the etiology of depression and may be responsible for the high incidence of co-morbid depression associated in diseases with glutamate etiology. While depression is a syndrome with multiple possible etiologies, we propose that a disruption in glutamatergic neurotransmission may underline a substantial proportion of clinically observed depression. The high rates of depressive symptoms associated with various disorders in which altered glutamatergic functions have been identified, may suggest a common pathophysiological mechanism is underlying the diverse clinical presentations.

Abstract
Tobacco addiction and chronic pain represent 2 highly prevalent and comorbid conditions that engender substantial burdens upon individuals and systems. Interrelations between pain and smoking have been of clinical and empirical interest for decades, and research in this area has increased dramatically over the past 5 years. We conceptualize the interaction of pain and smoking as a prototypical example of the biopsychosocial model. Accordingly, we extrapolated from behavioral, cognitive, affective, biomedical, and social perspectives to propose causal mechanisms that may contribute to the observed comorbidity between these 2 conditions. The extant literature was 1st dichotomized into investigations of either effects of smoking on pain or effects of pain on smoking. We then integrated these findings to present a reciprocal model of pain and smoking that is hypothesized to interact in the manner of a positive feedback loop, resulting in greater pain and increased smoking. Finally, we proposed directions for future research and discussed clinical implications for smokers with comorbid pain disorders. We observed modest evidence that smoking may be a risk factor in the multifactorial etiology of some chronically painful conditions and that pain may come to serve as a potent motivator of smoking. We also found that whereas animal studies yielded consistent support for direct pain-inhibitory effects of nicotine and tobacco, results from human studies were much less consistent. Future research in the emerging area of pain and smoking has the potential to inform theoretical and clinical applications with respect to tobacco smoking, chronic pain, and their comorbid presentation.

Abstract
UNLABELLED Pain complaints are commonly reported symptoms among postmenopausal women and can have significant effects on health-related quality of life. We sought to identify medical and psychosocial factors that predict changes in pain and overall physical functioning over a 3-year period among postmenopausal women with recurrent pain conditions. We examined data from postmenopausal women age 50 to 79 with recurrent pain conditions (low back pain, neck pain, headache or migraines, or joint pain or stiffness) over a 3-year period using the Women's Health Initiative Observational Study Cohort (N = 67,963). Multinomial logistic regression models controlling for demographic and clinical characteristics were used to identify baseline predictors of change in the SF-36 subscales for pain and physical functioning between baseline and 3-year follow-up. Body mass index (BMI) was associated with worsening of pain (OR [95% CI] 1.54 [1.45-1.63] for BMI ≥30) and physical functioning (1.83 [1.71-1.95] for BMI ≥30). A higher reported number of nonpain symptoms, higher medical comorbidity, and a positive screen for depression (1.13 [1.05-1.22] for worsened pain) were also associated with worsening of pain and physical functioning. Baseline prescription opioid use was also associated with lack of improvement in pain (OR .42, 95% CI .36-.49) and with worsened physical functioning (1.25 [1.04-1.51]). PERSPECTIVE This study presents prospective data on change in pain and physical functioning in postmenopausal women over a 3-year period. Our results suggest depression, nonpain physical symptoms, obesity, and possibly opioid treatment are associated with worse long-term pain outcomes in this population.

Abstract
CONTEXT Although the cross-sectional association between cancer-related pain and disability is well established, their longitudinal relationship has been less studied. OBJECTIVES Data from the Indiana Cancer Pain and Depression (INCPAD) trial were analyzed to determine whether baseline cancer-related pain and changes in pain over time predict disability over 12 months. METHODS A total of 274 cancer survivors with cancer-related pain were accrued in the INCPAD trial. Data were collected at baseline, one, three, six, and 12 months by interviewers blinded to treatment arm. Disability outcomes included a continuous measure (Sheehan Disability Scale [SDS] score) and a categorical measure (≥14 days in the past four weeks with a ≥50% reduction in usual activities). Predictor variables, operationalized by the Brief Pain Inventory, included baseline pain severity and changes in pain severity scores between each time point. Multivariable analyses were conducted adjusting for treatment group, baseline disability, and selected covariates including depression. RESULTS Baseline pain severity did not predict disability outcomes at 12 months. However, improvement in pain severity predicted less disability over 12 months both in terms of SDS scores (b=-0.17, t=-5.33, P<0.001) and ≥14 disability days in the past month (odds ratio=0.85; 95% confidence interval, 0.79-0.93; P<0.001). CONCLUSION Disability over 12 months in patients with cancer-related pain is predicted by changes in pain severity over time. Results suggest that effective pain management may reduce subsequent disability among cancer survivors.

Abstract
The aim of this article is to review the association between somatic symptoms, anxiety disorders and substance use. A Pub Med based literature review was conducted using various combinations of keywords related to substance use, somatic symptoms and anxiety. In various studies somatic symptoms were found to be associated with substance use. Anxiety disorders were found to have a high co-morbidity with substance use in most studies. However, several of the reviewed studies also included depressive symptoms which might have confounded the results. None of the studies was specifically aimed to find out if somatic symptoms in substance users represent an underlying primary anxiety disorder. Somatic symptoms and anxiety disorders are commonly noticed in substance users. Further studies are needed to clarify these associations since they may have significant clinical implications.

Abstract
This article outlines the development and usability-feasibility testing of an automated text-messaging adjunct to cognitive- behavioral therapy (CBT) for depression in a public sector clinic serving low-income patients. The text-messaging adjunct is aimed at increasing homework adherence, improving self-awareness, and helping track patient progress. Daily text messages were sent to patients, inquiring about their mood. Additional daily messages corresponded to themes of a manualized group CBT intervention. These included (1) thought tracking (both positive and negative), (2) tracking of pleasant activities, (3) tracking of positive and negative contacts, and (4) tracking of physical well-being. We tested the adjunct in 2 CBT groups (1 English & 1 Spanish) consisting of 12 patients total during and after treatment. Participants responded at a rate of 65% to text messages, and they reported overall positive experiences. We propose that text messaging has the potential to improve mental health care broadly, and among low-income populations specifically, with cost-effective means.

Abstract
We investigated the association of chronic pain with physical and mental comorbidity in the New Zealand population by measuring chronic pain status separate from comorbid conditions. Models of allostatic load provided a conceptual basis for considering multi-morbidity as accumulated comorbid load and for using both discrete conditions and cumulative measures in analyses. The nationally representative cross-sectional survey data included self-reported doctor-diagnosed chronic physical and mental health conditions, Kessler 10-item scale scores, an independent measure of chronic pain, and sociodemographic characteristics. The population prevalence of chronic pain is 16.9%, and a quarter (26%) of the population report 2 or more comorbid physical conditions statistically associated with chronic pain (unadjusted P<0.01). Results indicate that accumulated comorbid load is independently associated with chronic pain. Six physical conditions independently associated with chronic pain (adjusted odds range from 1.4 to 3.9) increase the risk of chronic pain in an additive manner, and residual accumulated load further increases risk for 2 or more conditions (adjusted odds 1.6). Anxiety/depression interacts synergistically with arthritis and neck/back disorders to increase the odds of reporting chronic pain beyond an additive model. This synergistic effect is not apparent for other conditions or for additional comorbid load. Results imply that measurement of chronic pain independent of comorbid conditions and adjustment for comorbid conditions is important for more accurate prevalence estimates and understanding relationships between conditions. Future epidemiological research might usefully incorporate independent measurement of chronic pain alongside adjustment for specific physical and mental health conditions as well as accumulated comorbid load.

Abstract
An apparent clinical relationship between pain and depression has long been recognized. Depression and pain are often diagnosed in the same patients. The emerging concept for pain-depression pathogenesis is the dysfunction of biogenic amine-mediated pain-depression control and the possible involvement of nitrodative stress-induced neurogenic inflammation. The present study was designed to investigate the effect of curcumin on reserpine-induced pain-depression dyad in rats. Administration of reserpine (1mg/kg subcutaneous daily for three consecutive days) led to a significant decrease in nociceptive threshold as evident from reduced paw withdrawal threshold in Randall Sellitto and von-Frey hair test as well as significant increase in immobility time in forced swim test. This behavioural deficit was integrated with decrease in the biogenic amine (dopamine, norepinephrine and serotonin) levels along with increased substance P concentration, nitrodative stress, inflammatory cytokines, NF-κβ and caspase-3 levels in different brain regions (cortex and hippocampus) of the reserpinised rats. Curcumin (100, 200, 300mg/kg; ip) dose dependently ameliorated the behavioural deficits associated with pain and depression by restoring behavioural, biochemical, neurochemical and molecular alterations against reserpine-induced pain-depression dyad in rats.
