Abstract
BACKGROUND Cervical spondylosis (CS) is a prevalent disorder that can have a major negative impact on quality of life. Traditional conservative treatment has limited efficacy, and electroacupuncture (EA) is a novel treatment option. We investigated the application and molecular mechanism of EA treatment in a rat model of cervical intervertebral disk degeneration (CIDD). METHODS The CIDD rat model was established, following which rats in the electroacupuncture (EA) group received EA. For overexpression of IL-22 or inhibition of JAK2-STAT3 signaling, the rats were injected intraperitoneally with recombinant IL-22 protein (p-IL-22) or the JAK2-STAT3 (Janus kinase 2-signal transducer and activator of transcription protein 3) inhibitor AG490 after model establishment. Rat nucleus pulposus (NP) cells were isolated and cultured. Cell counting kit-8 and flow cytometry were used to analyze the viability and apoptosis of the NP cells. Expression of IL-22, JAK2 and STAT3 was determined using RT-qPCR. Expression of IL-22/JAK2-STAT3 pathway and apoptosis related proteins was detected by Western blotting (WB). RESULTS EA protected the NP tissues of CIDD rats by regulating the IL-22/JAK2-STAT3 pathway. Overexpression of IL-22 significantly promoted the expression of tumor necrosis factor (TNF)-α, IL-6, IL-1β, matrix metalloproteinase (MMP)3 and MMP13 compared with the EA group. WB demonstrated that the expression of IL-22, p-JAK2, p-STAT3, caspase-3 and Bax in NP cells of the EA group was significantly reduced and Bcl-2 elevated compared with the model group. EA regulated cytokines and MMP through activation of IL-22/JAK2-STAT3 signaling in CIDD rat NP cells. CONCLUSION We demonstrated that EA affected apoptosis by regulating the IL-22/JAK2-STAT3 pathway in NP cells and reducing inflammatory factors in the CIDD rat model. The results extend our knowledge of the mechanisms of action underlying the effects of EA as a potential treatment approach for CS in clinical practice.

Abstract
Background The use of multidisciplinary treatment programs in out-of-hospital healthcare is a new area of research. Little is known about the benefits of this method in the management of discharged patients undergoing cervical spondylosis surgery. Objective This study aimed to explore the effect of a contracted-based, multidisciplinary follow-up plan in patients after cervical spondylosis surgery. Methods This non-blinded non-randomized controlled study was conducted with 88 patients (44 in the intervention group, 44 in the control group). The clinical outcomes, including Neck Disability Index (NDI), pain score (VAS), Self-Efficacy for Managing Chronic Disease 6-item Scale (SECD-6), and 12-Item Short-Form Health Survey (SF-12) score were assessed at the time of discharge, 24-72 h, 1 month, and 3 months post-discharge. The complications, patient satisfaction, and economic indicators were assessed at the final follow-up (3 months). Results Patients who received contracted follow-up showed greater improvement in neck dysfunction at 24-72 h, 1 month, and 3 months after discharge compared to those who received routine follow-up (p < 0.001). At 1 month after discharge, the intervention group exhibited better self-efficacy (p = 0.001) and quality of life (p < 0.001) than the control group, and these improvements lasted for 3 months. The intervention group reported lower pain scores at 24-72 h and 1 month (p = 0.008; p = 0.026) compared to the control group. The incidence of complications was significantly lower in the intervention group (11.4%) compared to the control group (40.9%). The total satisfaction score was significant difference between the two groups (p < 0.001). Additionally, the intervention group had lower direct medical costs (p < 0.001), direct non-medical costs (p = 0.035), and total costs (p = 0.04) compared to the control group. However, there was no statistically significant difference in indirect costs between the two groups (p = 0.59). Conclusion A multidisciplinary contract follow-up plan has significant advantages regarding neck disability, self-efficacy, quality of life, postoperative complications, patient satisfaction, and direct costs compared with routine follow-up.

Abstract
BACKGROUND Intervertebral disc degeneration (IVDD) is a common degenerative condition, which is thought to be a major cause of lower back pain (LBP). However, the etiology and pathophysiology of IVDD are not yet completely clear. PURPOSE To examine potential causal effects of modifiable risk factors on IVDD. STUDY DESIGN Bidirectional Mendelian randomization (MR) study. PATIENT SAMPLE Genome-wide association studies (GWAS) with sample sizes between 54,358 and 766,345 participants. OUTCOME MEASURES Outcomes included (1) modifiable risk factors associated with IVDD use in the forward MR; and (2) modifiable risk factors that were determined to have a causal association with IVDD in the reverse MR, including smoking, alcohol intake, standing height, education level, household income, sleeplessness, hypertension, hip osteoarthritis, HDL, triglycerides, apolipoprotein A-I, type 2 diabetes, fasting glucose, HbA1c, BMI and obesity trait. METHODS We obtained genetic variants associated with 33 exposure factors from genome-wide association studies. Summary statistics for IVDD were obtained from the FinnGen consortium. The risk factors of IVDD were analyzed by inverse variance weighting method, MR-Egger method, weighted median method, MR-PRESSO method and multivariate MR Method. Reverse Mendelian randomization analysis was performed on risk factors found to be caustically associated with IVDD in the forward Mendelian randomization analysis. The heterogeneity of instrumental variables was quantified using Cochran's Q statistic. RESULTS Genetic predisposition to smoking (OR=1.221, 95% CI: 1.068-1.396), alcohol intake (OR=1.208, 95% CI: 1.056-1.328) and standing height (OR=1.149, 95% CI: 1.072-1.231) were associated with increased risk of IVDD. In addition, education level (OR=0.573, 95%CI: 0.502-0.654)and household income (OR=0.614, 95%CI: 0.445-0.847) had a protective effect on IVDD. Sleeplessness (OR=1.799, 95%CI: 1.162-2.783), hypertension (OR=2.113, 95%CI: 1.132-3.944) and type 2 diabetes (OR=1.069, 95%CI: 1.024-1.115) are three important risk factors causally associated with the IVDD. In addition, we demonstrated that increased levels of triglycerides (OR=1.080, 95%CI:1.013-1.151), fasting glucose (OR=1.189, 95%CI:1.007-1.405), and HbA1c (OR=1.308, 95%CI:1.017-1.683) could significantly increase the odds of IVDD. Hip osteoarthritis, HDL, apolipoprotein A-I, BMI and obesity trait factors showed bidirectional causal associations with IVDD, therefore we considered the causal associations between these risk factors and IVDD to be uncertain. CONCLUSIONS This MR study provides evidence of complex causal associations between modifiable risk factors and IVDD. It is noteworthy that metabolic disturbances appear to have a more significant effect on IVDD than biomechanical alterations, as individuals with type 2 diabetes, elevated triglycerides, fasting glucose, and elevated HbA1c are at higher risk for IVDD, and the causal association of obesity-related characteristics with IVDD incidence is unclear. These findings provide new insights into potential therapeutic and prevention strategies. Further research is needed to clarify the mechanisms of these risk factors on IVDD.

[PMID: 36435725 DOI: 10.1016/j.jos.2022.10.018] [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: 09/01/2022] [Revised: 10/21/2022] [Accepted: 10/27/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Postoperative outcomes following cervical spondylotic myelopathy (CSM) are excellent overall, but there are few prospective studies using patient-reported outcome measures that have explored how long improvement can be expected after surgery. The aim of this prospective study was to investigate from when and until when symptoms improve after open-door laminoplasty in patients with CSM and the factors that affect surgical outcomes. METHODS The subjects were 115 CSM patients who underwent laminoplasty. The Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) was used for longitudinal evaluation, and surveys on cervical spine function, upper extremity function, lower extremity function, bladder function, and quality of life were conducted before surgery and at 3, 6, 12, 18, and 24 months after surgery. The patients were classified into 'effective' and 'ineffective' groups based on the points obtained for each domain, and the factors affecting the outcome of surgery were examined by multivariate analysis. RESULTS JOACMEQ scores improved significantly at 3 months postoperatively compared to preoperatively for all four domains except cervical spine function, but there was no significant improvement after 3 months postoperatively. Multivariate analysis showed that the preoperative score (cervical spine function and upper extremity function) and the points obtained at 3 months postoperatively (upper and lower extremity function, bladder function, and quality of life) were the factors associated with membership of the effective group at 24 months postoperatively. CONCLUSIONS Although upper and lower extremity function, bladder function, and quality of life domains improved in the relatively early postoperative period, improvement after 3 months postoperatively was limited. The results suggest that the preoperative score and the superiority of the improvement obtained up to 3 months after surgery may be indicators of postoperative outcomes, and this may provide new insights into the selection of surgical indications and patient explanations.

Toward Shared Decision-Making in Degenerative Cervical Myelopathy: Protocol for a Mixed Methods Study. JMIR Res Protoc 2023; 12:e46809. [PMID: 37812472 PMCID: PMC10594151 DOI: 10.2196/46809] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 06/07/2023] [Accepted: 06/08/2023] [Indexed: 10/10/2023] Open
Abstract
BACKGROUND Health care decisions are a critical determinant in the evolution of chronic illness. In shared decision-making (SDM), patients and clinicians work collaboratively to reach evidence-based health decisions that align with individual circumstances, values, and preferences. This personalized approach to clinical care likely has substantial benefits in the oversight of degenerative cervical myelopathy (DCM), a type of nontraumatic spinal cord injury. Its chronicity, heterogeneous clinical presentation, complex management, and variable disease course engenders an imperative for a patient-centric approach that accounts for each patient's unique needs and priorities. Inadequate patient knowledge about the condition and an incomplete understanding of the critical decision points that arise during the course of care currently hinder the fruitful participation of health care providers and patients in SDM. This study protocol presents the rationale for deploying SDM for DCM and delineates the groundwork required to achieve this. OBJECTIVE The study's primary outcome is the development of a comprehensive checklist to be implemented upon diagnosis that provides patients with essential information necessary to support their informed decision-making. This is known as a core information set (CIS). The secondary outcome is the creation of a detailed process map that provides a diagrammatic representation of the global care workflows and cognitive processes involved in DCM care. Characterizing the critical decision points along a patient's journey will allow for an effective exploration of SDM tools for routine clinical practice to enhance patient-centered care and improve clinical outcomes. METHODS Both CISs and process maps are coproduced iteratively through a collaborative process involving the input and consensus of key stakeholders. This will be facilitated by Myelopathy.org, a global DCM charity, through its Research Objectives and Common Data Elements for Degenerative Cervical Myelopathy community. To develop the CIS, a 3-round, web-based Delphi process will be used, starting with a baseline list of information items derived from a recent scoping review of educational materials in DCM, patient interviews, and a qualitative survey of professionals. A priori criteria for achieving consensus are specified. The process map will be developed iteratively using semistructured interviews with patients and professionals and validated by key stakeholders. RESULTS Recruitment for the Delphi consensus study began in April 2023. The pilot-testing of process map interview participants started simultaneously, with the formulation of an initial baseline map underway. CONCLUSIONS This protocol marks the first attempt to provide a starting point for investigating SDM in DCM. The primary work centers on developing an educational tool for use in diagnosis to enable enhanced onward decision-making. The wider objective is to aid stakeholders in developing SDM tools by identifying critical decision junctures in DCM care. Through these approaches, we aim to provide an exhaustive launchpad for formulating SDM tools in the wider DCM community. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID) DERR1-10.2196/46809.

Abstract
BACKGROUND Degenerative cervical myelopathy (DCM) is the most common cause of chronic, progressive spinal cord impairment worldwide. Patients experience substantial pain, functional neurological decline and disability. Health-related quality of life (HRQoL) appears to be particularly poor, even when compared to other chronic diseases. However, the determinants of HRQoL are poorly understood. The objective was to perform a systematic review of the determinants of quality of life of people with DCM. METHODS A systematic search was conducted in MEDLINE and Embase following PRISMA 2020 guidelines (PROSPERO CRD42018115675). Full-text papers in English, exclusively studying DCM, published before 26 March 2020 were eligible for inclusion and were assessed using the Newcastle-Ottawa Scale and the Cochrane Risk of Bias 2 (RoB 2) tool. Study sample characteristics, patient demographics, cohort type, HRQoL instrument utilised, HRQoL score, and relationships of HRQoL with other variables were qualitatively synthesised. RESULTS A total of 1176 papers were identified; 77 papers and 13,572 patients were included in the final analysis. A total of 96% of papers studied surgical cohorts and 86% utilised the 36-Item Short Form Survey (SF-36) as a measure of HRQoL. HRQoL determinants were grouped into nine themes. The most common determinant to be assessed was surgical technique (38/77, 49%) and patient satisfaction and experience of pain (10/77, 13%). HRQoL appeared to improve after surgery. Pain was a negative predictor of HRQoL. CONCLUSION Current data on the determinants of HRQoL in DCM are limited, contradictory and heterogeneous. Limitations of this systematic review include lack of distinction between DCM subtypes and heterogenous findings amongst the papers in which HRQoL is measured postoperatively or post-diagnosis. This highlights the need for greater standardisation in DCM research to allow further synthesis. Studies of greater precision are necessary to account for HRQoL being complex, multi-factorial and both time and context dependent.

Abstract
Background Pre-operative depression and anxiety are associated with poorer patient-reported outcomes following cervical spine surgery. Identification of and interventions for these disorders are key to preventing related negative effects. However, most spine surgeons do not routinely evaluate mental health disorders. Few studies have investigated which patients with cervical degenerative disc diseases (CDDD) are susceptible to depression and anxiety. Objective To determine the factors associated with depression and anxiety in patients with CDDD. Methods Three hundred twelve patients with CDDD were recruited in this cross-sectional case-control study. Patients underwent a structured interview to acquire demographic and clinical characteristic information, which included the Neck Disability Index (NDI), modified Japanese Orthopedic Association (mJOA), and Visual Analog Scale (VAS) for neck/arm pain. Depression and anxiety were evaluated using the Zung Self-Rating Depression and Anxiety Scales. Univariate and multivariate logistic regression analyses were used to identify factors associated with depression and anxiety. Results Of all patients, 102 (32.7%) had depression and 92 (29.5%) had anxiety. Two hundred six (66.0%) patients with neither depression nor anxiety were defined as the control group. Univariate analysis indicated that gender, educational level, occupation type, Charlson comorbidity index, symptom duration, symptomatology, surgery history, NDI, mJOA, VAS-neck, and VAS-arm scores were associated with depression and anxiety (except for symptom duration for anxiety). Multivariate logistic regression analysis indicated that females [odds ratio (OR) 1.81, 95% confidence interval (CI) 1.01-3.23], physical work (OR 2.06, 95% CI 1.16-3.65), poor mJOA score (ORmoderate 2.67, 95% CI 1.40-5.07; ORsevere 7.63, 95% CI 3.85-15.11), and high VAS-neck score (OR 1.24, 95% CI 1.11-1.39) were independent risk factors for depression. Physical work (OR 1.84, 95% CI 1.01-3.35), poor mJOA score (ORmoderate 2.66, 95% CI 1.33-5.33; ORsevere 9.26, 95% CI 4.52-18.99), and high VAS-neck score (OR 1.34, 95% CI 1.19-1.51) were independent risk factors for anxiety. Conclusion Approximately one-third of patients with CDDD had depression or anxiety. Patients who engaged in heavy work and had severe symptoms (poor mJOA and high VAS-neck scores) are susceptible to depression and anxiety. Additionally, female patients are susceptible to depression. Our findings may help identify CDDD patients with depression and anxiety in clinical practice.

Abstract
BACKGROUND Individuals with lifelong illnesses need access to adequate information about their condition to make optimal health decisions. Degenerative Cervical Myelopathy (DCM) is the most common form of spinal cord dysfunction in adults worldwide. Its chronic and debilitating nature, varied impact, clinical trajectory, and management options necessitate appropriate informational support to sustain effective clinical and self-directed care strategies. However, before clinicians can meet patients' information needs, they must first have an understanding of their baseline requirements. This study explores the information needs of people with DCM (PwCM). In doing so, it provides a starting point for the development of patient education and knowledge management strategies in clinical practice. METHODS Semi-structured interviews with PwCM were conducted using an interview guide. Interviews were audio-recorded and transcribed verbatim. Thematic analysis according to Braun and Clarke's six-phase approach was used to analyse the data. Findings were reported according to the Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines. RESULTS Twenty PwCM (65% female, 35% male), with ages ranging from 39 to 74 years old participated in the interviews. The findings indicated that the provision of information to PwCM during clinical interactions varies. Accordingly, PwCM's information needs were broad-ranging, as was the nature of the information they found useful. Three main themes were identified (1) Variation in the provision of information to PwCM during clinical interactions, (2) Variations in the information needs of PwCM, and (3) Information that PwCM find useful. CONCLUSION Efforts must turn to adequately educating patients at the time of the clinical encounter. A comprehensive and consistent patient-centered information exchange in DCM is necessary to achieve this.

Comparison of health-related quality of life in patients with traumatic brain injury, subarachnoid haemorrhage and cervical spine disease. Br J Neurosurg 2022:1-7. [PMID: 36495241 DOI: 10.1080/02688697.2022.2152777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 11/23/2022] [Indexed: 12/14/2022]
Abstract
PURPOSE The degree of disability that is acceptable to patients following traumatic brain injury (TBI) continues to be debated. While the dichotomization of outcome on the Glasgow Outcome Score (GOSE) into 'favourable' and 'unfavourable' continues to guide clinical decisions, this may not reflect an individual's subjective experience. The aim of this study is to assess how patients' self-reported quality of life (QoL) relates to objective outcome assessments and how it compares to other debilitating neurosurgical pathologies, including subarachnoid haemorrhage (SAH) and cervical myelopathy. METHOD A retrospective analysis of over 1300 patients seen in Addenbrooke's Hospital, Cambridge, UK with TBI, SAH and patients pre- and post- cervical surgery was performed. QoL was assessed using the SF-36 questionnaire. Kruskal-Wallis test was used to analyse the difference in SF-36 domain scores between the four unpaired patient groups. To determine how the point of dichotomization of GOSE into 'favourable' and 'unfavourable' outcome affected QOL, SF-36 scores were compared between GOSE and mRS. RESULTS There was a statistically significant difference in the median Physical Component Score (PCS) and Mental Component Score (MCS) of SF-36 between the three neurosurgical pathologies. Patients with TBI and SAH scored higher on most SF-36 domains when compared with cervical myelopathy patients in the severe category. While patients with Upper Severe Disability on GOSE showed significantly higher PC and MC scores compared to GOSE 3, there was a significant degree of variability in individual responses across the groups. CONCLUSION A significant number of patients following TBI and SAH have better self-reported QOL than cervical spine patients and patients' subjective perception and expectations following injury do not always correspond to objective disability. These results can guide discussion of treatment and outcomes with patients and families.

History of Prior Lumbar Surgery Does Not Impact Mental Health Outcomes Following Anterior Cervical Discectomy and Fusion. Clin Spine Surg 2022; 35:E737-E742. [PMID: 35696709 DOI: 10.1097/bsd.0000000000001355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 05/18/2022] [Indexed: 01/25/2023]
Abstract
STUDY DESIGN This was a retrospective cohort study. OBJECTIVE The objective of this study was to evaluate the impact of undergoing a prior lumbar procedure on mental health outcomes following anterior cervical discectomy and fusion. SUMMARY OF BACKGROUND DATA Revision and reoperations are perceived as risk factors for worse mental health outcomes. METHODS A retrospective review of a surgical database was performed for cervical and lumbar procedures. The mental health measures used were: Short Form 12-Item Mental Composite Score (SF-12 MCS) and Patient Health Questionnaire 9 (PHQ-9). Secondary outcomes of interest were Visual Analogue Scale for neck and arm pain, Neck Disability Index, and Short Form 12-Item Physical Composite Score (SF-12 PCS). All outcomes were collected preoperatively and at 6 weeks, 12 weeks, 6 months, and 1 year postoperatively. Minimum clinically important difference (MCID) was calculated using established values. Patients were grouped based on the surgical history of an elective lumbar spine procedure and propensity-matched. Differences in postoperative outcome scores and MCID achievement were evaluated using linear and logistic regression respectively. RESULTS A total of 74 patients were included in this study. Mental health outcomes did not demonstrate significant differences between groups for SF-12 MCS and PHQ-9 for all time points except at 6 weeks for PHQ-9 ( P =0.038). MCID achievement was not significantly impacted by surgical history for all outcome measures at all postoperative time points (all P >0.050). The majority of patients achieved an MCID by the 1-year time point for all outcomes for patients without a prior lumbar surgery except for Visual Analogue Scale arm and SF-12 PCS, while those with a surgical history achieved an MCID for all outcomes except SF-12 PCS and PHQ-9. CONCLUSIONS Anterior cervical discectomy and fusion patients with a past history of lumbar surgery demonstrated significant improvements in depression, neck and arm pain, disability, and physical function as those without a past lumbar surgical history. Prior surgery also did not impact MCID achievement for all outcomes.

Impact of Prolonged Duration of Symptoms on Mental Health in Anterior Cervical Disectomy and Fusion Patients. J Am Acad Orthop Surg 2022; 30:e74-e82. [PMID: 34343162 DOI: 10.5435/jaaos-d-21-00050] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 07/04/2021] [Indexed: 02/01/2023] Open
Abstract
INTRODUCTION Prolonged duration of symptoms is associated with worse pain and disability in patients undergoing anterior cervical discectomy and fusion (ACDF). Our study aims to determine the effect of symptom duration on severity of depression among ACDF patients. METHODS We retrospectively reviewed a prospective surgical database from 2006 to 2019 for primary, single, or multilevel ACDF. Patients missing the duration of symptom information or patient-reported outcome measures (PROMs) were excluded. PROMs included Patient Health Questionnaire-9, 12-Item Short Form Mental Component Score, and 12-Item Veterans RAND Mental Component Score and were collected at preoperative, 6-week, 12-week, 6-month, 1-year, and 2-year timepoints. The minimum clinically important difference (MCID) was calculated using the established values. Patients were categorized based on preoperative duration of symptoms as follows: <6 months, ≥6 months and <1 year, 1 to 2 years, and >2 years. Univariate analysis was done to determine differences in demographics and perioperative characteristics. Intergroup differences in PROMs and MCID achievement were evaluated using linear regression and logistic regression, respectively. RESULTS Two hundred thirty-one ACDF patients included had a mean age of 49.6 years and most were male (61.0%) and nonobese (<30 kg/m2; 55.0%). The groups differed by their American Society of Anesthesiologists classification (P = 0.029), workers' compensation status (P = 0.022), and diagnosis of herniated nucleus pulposus (P = 0.010). Postoperative mental health outcomes did not significantly differ between duration groups except for Veterans Rand-12 Mental Component Score at 12 weeks (P = 0.044). MCID achievement rates did not significantly differ. CONCLUSION Patients undergoing ACDF largely did not demonstrate differences in mental health scores or achievement of MCID based on the duration of symptoms.

Abstract
OBJECTIVE To evaluate whether depression is the contraindication of anterior cervical decompression and fusion (ACDF) for cervical spondylosis. MATERIAL AND METHODS Patients with single-segment cervical spondylosis who underwent ACDF from January 2015 to December 2018 in our department were retrospectively included in this study and divided into two groups. Patients who were diagnosed of depression and prescribed with antidepressant drugs for at least 6 months before surgery were included in the intervention group. Patients without depression were included in the control group. The Beck Depression Inventory (BDI) score was used to evaluate the severity of depression. Visual Analogue Scale (VAS) score, Japanese Orthopeadic Association (JOA) score, Neck Disability Index (NDI), and the 36-Item Short-Form Health Survey (SF-36) were recorded as indexes to assess the pain, cervical spine function, degree of cervical spine injury, and life quality, respectively. The operative time, operative blood loss, hospital stay and complications were also recorded and compared. RESULTS A total of 117 patients were included in this study, involving 32 patients in the intervention group and 85 patients in the control group. No significant differences were found in operative time, operative blood loss, hospital stay and complications between the two groups (P>0.05). The BDI score, VAS score, JOA score, NDI, SF-36 physical component score (SF-36 PCS) and SF-36 mental component score (SF-36 MCS) were all significantly improved at last follow-up in both the two groups. The intervention group showed higher BDI score and SF-36 MCS than the control group at both preoperative and the last follow-up (P<0.05), and the improvements of BDI score and SF-36 MCS were also higher in the intervention group (P<0.05). Although the intervention group showed higher VAS score, NDI, SF-36 PCS and lower JOA score at preoperative and last follow-up, respectively (P<0.05), there were no significant differences in the improvements of these indexes between the two group (P>0.05). CONCLUSIONS Depression is not the contraindication of ACDF for cervical spondylosis. Depression patients who received preoperative antidepressants can achieve similar improvement of clinical symptoms from ACDF with non-depression patients.

The prevalence of depression in degenerative spine disease patients: A systematic review and meta-analysis. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2021; 30:3417-3427. [PMID: 34476597 DOI: 10.1007/s00586-021-06977-z] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Revised: 08/19/2021] [Accepted: 08/23/2021] [Indexed: 02/08/2023]
Abstract
PURPOSE To estimate the prevalence of depression in degenerative spine disease (DSD) patients. METHODS The PubMed, EMBASE, and PsycINFO were systematically searched, the relevant studies that reported the depression prevalence of in DSD patients were identified. Data were extracted independently by 2 reviewers. Subgroup analysis and sensitivity analysis were also performed. RESULTS 24 articles met the inclusion criteria and were selected for the current study. The pooled prevalence estimate of depression in DSD patients before operative treatment was 30.8% [95% CI 24.0-38.5%]. Nine articles reported the prevalence rate in DSD patients after operative treatment, and the pooled prevalence estimate was 27.0% [95% CI 19.9-35.4%]. There were significant differences for prevalence estimates before operative treatment in types of disorders (Q = 4.56, P = 0.10), spine surgery history (Q = 5.55, P = 0.02), representativeness of sample (Q = 11.00, P = 0.00), and validity of assessment method (Q = 3.32, P = 0.07). The prevalence estimates in patients with lumbar spine stenosis, lumbar disc herniation and cervical spondylotic myelopathy were 24.0%, 40.9% and 37.3%, respectively. Studies that included patients with a history of spine surgery yielded a more extreme prevalence estimate than studies excluding those (36.9% vs 24.3%). For results of patients after operative treatment, significant differences for prevalence estimates were showed in different degrees of pain (Q = 4.72, P = 0.03), screening instruments (Q = 4.83, P = 0.09), and representativeness of sample (Q = 15.70, P = 0.00). CONCLUSION The systematic review indicated increased prevalence of depression in DSD patients. In consideration of the relationship between depression and poor surgical outcome, we should pay more attention to identifying strategies for preventing and treating depression in DSD patients.

Spine J 2021; 21:586-597. [PMID: 33434649 DOI: 10.1016/j.spinee.2021.01.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 12/01/2020] [Accepted: 01/04/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT The clinical symptoms of cervical myelopathy (CM) are closely associated with the risk factors of sleep disturbance, and its pathophysiological process is similar to that of spinal cord injury. Therefore, patients with CM are also expected to have sleep disturbance like patients with spinal cord injury, who typically have various types of sleep disorders. Fortunately, sleep disturbance in patients with CM is expected to respond well to treatment, and clinical studies are required to establish proper treatment strategies for CM patients with sleep disturbance. PURPOSE To compare the effects of CM treatment on sleep quality between patients treated surgically and those managed conservatively and to identify predictors associated with sleep improvement. STUDY DESIGN/SETTING Prospective cohort study. PATIENT SAMPLE Patients diagnosed as having CM. OUTCOME MEASURES Pittsburgh Sleep Quality Index (PSQI). METHODS The effect of CM treatment on sleep improvement at the 6-month follow-up was evaluated using a multivariate logistic regression analysis of propensity score-matched patients. To investigate factors associated with significant sleep improvement, a subgroup analysis was performed. RESULTS A total of 131 patients with CM and sleep disturbance were enrolled. Among these patients, 31 received surgical treatment and 100 received conservative treatment. Sleep quality improved rapidly and consistently after surgery, and significant sleep improvement was observed in most of the patients in the surgical group (26/31 patients, 83.9%) at the 6-month follow-up. However, sleep improvement only occurred in 27 (27%) of the 100 patients in the conservative group at the 6-month follow-up. The subgroup analysis revealed that the degree of CM determined by mJOA scores >13 was a significant predictor of sleep improvement after conservative treatment. CONCLUSIONS Clinicians should closely monitor patients with CM with sleep disturbance, and proper treatment strategies should be considered according to the severity of the conditions.

Abstract
BACKGROUND CONTEXT Sleep disturbance is highly prevalent in patients with spinal cord injury and is one of the most important clinical issues affecting their quality of life. However, it has not been properly measured or treated in patients with cervical myelopathy (CM), although most typical or atypical symptoms of CM are known to be risk factors for sleep disturbance. In addition, previous studies identified that the presence of sleep disturbance is unintentionally missed under the current evaluation process for degenerative spinal disease without direct investigation using validated tools for sleep. Therefore, studies about sleep disturbances in patients with CM are essential. PURPOSE The purpose of this study was to investigate the prevalence of sleep disturbance in patients with CM using validated tools and to understand its mechanism by identifying high-risk patients. STUDY DESIGN/SETTING Cross-sectional study. PATIENT SAMPLE Consecutive patients diagnosed with CM. OUTCOME MEASURES Pittsburgh sleep quality index. METHODS This study was performed on patients diagnosed with CM. Sleep disturbance was determined using the Pittsburgh sleep quality index. Variables associated with sleep disturbance including demographics, lifestyle, medical history, and radiologic parameters were investigated. Independent risk factors related to sleep disturbance were identified using multivariate logistic regression analysis. RESULTS A total of 203 patients with CM were included in our study. Among them, 126 patients (62.1%) were men, and the mean age was 63.0 years. Despite male predominance, sleep disturbance was identified in 71.4% of patients (145 of 203). Multivariate analysis identified a worse depression scale score, a lower modified Japanese Orthopedic Association score, chronic shoulder joint pain, smaller spinal cord area, and decreased cervical range of motion as independent risk factors for sleep disturbance. CONCLUSIONS In patients with CM, sleep disturbance was associated with a more severe type of myelopathy. Further studies including polysomnography and measurement of melatonin will be helpful to identify the mechanisms of the sleep disturbance in patients with CM and to improve their quality of life and clinical outcomes.

Abstract
Cervical spondylotic myelopathy (CSM) is a common disease of the elderly that is characterized by gait instability, sensorimotor deficits, etc. Recurrent symptoms including memory loss, poor attention, etc. have also been reported in recent studies. However, these have been rarely investigated in CSM patients. To investigate the cognitive deficits and their correlation with brain functional alterations, we conducted resting-state fMRI (rs-fMRI) signal variability. This is a novel indicator in the neuroimaging field for assessing the regional neural activity in CSM patients. Further, to explore the network changes in patients, functional connectivity (FC) and graph theory analyses were performed. Compared with the controls, the signal variabilities were significantly lower in the widespread brain regions especially at the default mode network (DMN), visual network, and somatosensory network. The altered inferior parietal lobule signal variability positively correlated with the cognitive function level. Moreover, the FC and the global efficiency of DMN increased in patients with CSM and positively correlated with the cognitive function level. According to the study results, (1) the cervical spondylotic myelopathy patients exhibited regional neural impairments, which correlated with the severity of cognitive deficits in the DMN brain regions, and (2) the increased FC and global efficiency of DMN can compensate for the regional impairment.

Abstract
STUDY DESIGN This was a retrospective study that was carried out using prospectively collected registry data. OBJECTIVE The objective of this study was to identify preoperative predictors of outcomes after anterior cervical discectomy and fusion (ACDF) for cervical spondylotic myelopathy. SUMMARY OF BACKGROUND DATA Proper patient selection is paramount to achieving good surgical results. Identifying predictors of outcomes may aid surgical decision-making and facilitate counseling of patients to manage expectations. METHODS Prospectively collected registry data of 104 patients who underwent single-level ACDF for cervical spondylotic myelopathy were reviewed. Outcomes assessed at 2 years were the presence of residual neck pain/arm pain (AP), and attainment of a minimal clinically important difference (MCID) for Neck Disability Index (NDI), Japanese Orthopaedic Association (JOA) score, and Physical Component Score (PCS) of SF-36, as well as patient satisfaction, fulfilment of expectations, willingness to undergo same surgery again, return to work (RTW), and return to function (RTF). Receiver operating characteristic curves and multivariate stepwise logistical regression were performed to identify independent predictors of each outcome using 22 covariates including demographics, comorbidities, and preoperative disease state. RESULTS Lower preoperative NDI was predictive of the absence of residual neck pain/AP at 2 years. Higher preoperative JOA score was predictive of MCID attainment for PCS, satisfaction, expectation fulfilment, willingness to undergo the same surgery for same condition, and RTF. Poorer preoperative scores of NDI, JOA, and PCS were predictors of attaining MCID of the respective scores. Older patients were less likely to attain MCID for JOA. Higher preoperative AP was a risk factor for unsuccessful RTW. CONCLUSIONS In general, the preoperative JOA score was the best predictor of outcomes after ACDF. A preoperative JOA cutoff value of 9.25-10.25 predicted satisfaction, expectation fulfilment, willingness to undergo same surgery, and RTF with at least 70% sensitivity and 50% specificity. These findings may aid surgeons in identifying patients at risk of a poor outcome and guide preoperative counseling to establish realistic expectations of the surgical outcome.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE The aim of this study was to evaluate the impact of cervical disc degeneration (CDD) severity on 2-year postoperative outcomes following laminoplasty. SUMMARY OF BACKGROUND DATA The impact of CDD on postoperative outcomes of cervical laminoplasty has not been well established. METHODS A total of 144 patients who underwent open-door laminoplasty for cervical spondylotic myelopathy (CSM) were enrolled. Six cervical discs were independently analyzed for degeneration severity using a previously reported grading system (grade 0: none, grade 3: severest). The relationship between the segmental range of motion (ROM) and the severity of CDD was evaluated. Subsequently, after dividing overall patients into mild and severe CDD groups by the average of CDD scores, the mixed-effect model was applied to assess 2-year postoperative outcomes, including physician-assessed myelopathy scores, patient-reported outcomes, and preoperative radiographic parameters. Finally, as additional analysis, the severe CDD group was further divided into two groups: group 1 included patients with a grade 3 CDD change in their most stenotic level and group 2 included the others. The 2-year postoperative myelopathy score was compared between groups 1 and 2. RESULTS The cervical segments with grade 3 CDD showed significantly smaller ROM compared with those with grade 0, 1, or 2 CDD (P < 0.01). There were no significant differences in postoperative improvements in myelopathy, pain, patient-reported physical and mental status, and radiographic parameters, except for quality of life (QOL) scores between CDD groups. A significant (P = 0.02) postoperative improvement in QOL scores was noted in the severe CDD group. In an additional analysis, myelopathy score at 2 years postoperatively was significantly higher in group 1 than group 2 (P = 0.041). CONCLUSION The severity of CDD did not negatively impact 2-year postoperative laminoplasty outcomes. The postulated reason is that the decreased segmental instability in the level with severe CDD may affect surgical outcomes positively. LEVEL OF EVIDENCE 3.

Abstract
BACKGROUND Anterior cervical discectomy and fusion (ACDF) and cervical disc arthroplasty (CDA) are both the effective techniques in treatment of cervical spondylosis. The purpose of this present retrospective cohort research was to assess the efficacy and safety of ACDF and CDA in treating the symptomatic cervical spondylosis over the 6-year follow-up. METHODS From our registry database, we identified retrospectively patients who received CDA or ACDF in our academic institutions from 2012 to 2015. The study was approved by the Institutional Review Board in Zigong No.4 People's Hospital (Z10058072). All the subjects who participated in this trial were informed consent in writing. The inclusion criteria were the degenerative disc diseases between C3-7 resulting in myelopathy or radiculopathy, which was unresponsive to the conservative treatment. The clinical results were determined via Short Form-36, and neck disability index, numerical scoring scales for complications, arm pain and neck pain. The radiographic assessment contained the cervical lordosis, and the motion range of the functional spinal unit and total cervical spine. The routine follow-up was performed to collect the data of radiographic and clinical assessment at 6, 12, 24, 48, and 72 months before and after the surgery. RESULTS This study had limited inclusion and exclusion criteria and a well-controlled intervention. It was assumed that both techniques could obtain the similar postoperative effects. TRIAL REGISTRATION This study protocol was registered in Research Registry (researchregistry5878).

Abstract
INTRODUCTION Degenerative cervical myelopathy (DCM) is a common, disabling and progressive neurological condition triggered by chronic compression of the cervical spinal cord by surrounding degenerative changes. Early diagnosis and specialist management are essential to reduce disability, yet time to diagnosis is typically prolonged. Lack of sufficient representation of DCM in undergraduate and postgraduate medical curricula may contribute to the poor recognition of DCM by non-specialist doctors in clinical practice.In this study, our objective, therefore, is to assess DCM teaching provision in medical schools throughout the UK and to assess the impact of teaching on the DCM knowledge of UK medical students. METHODS AND ANALYSIS A 19-item questionnaire capturing data on medical student demographics, myelopathy teaching and myelopathy knowledge was designed. Ethical approval was granted by the Psychology Research Ethics Committee, University of Cambridge. An online survey was hosted on Myelopathy.org, an international myelopathy charity. Students studying at a UK medical school are eligible for inclusion. The survey is advertised nationally through university social media pages, university email bulletins and the national student network of Myelopathy.org. Advertisements are scheduled monthly over a 12-month recruitment period. Participation is incentivised by entering consenting participants of completed surveys to an Amazon voucher prize draw. Responses are anonymised using participant-chosen unique identifier codes. A participant information sheet followed by an explicit survey question captures participant informed consent. Regular updates on the progress of the study will be published on Myelopathy.org. ETHICS AND DISSEMINATION Ethical approval for the study was granted by the Psychology Research Ethics Committee, University of Cambridge (PRE.2018.099). The findings of the study described in this protocol, and all other related work, will be submitted for publication in a peer-reviewed journal and will be presented at scientific conferences.

Abstract
Background Degenerative cervical myelopathy (DCM) is a common, chronic neurological condition that severely affects individuals by causing a range of disabling symptoms, frequently at a time around the peak of their careers. Subsequently, individuals with DCM often become dependent on informal care arrangements. The significant economic contribution of informal care and its burden on care providers are becoming increasingly recognized. Objective This study aimed to measure the quality of life of DCM informal caregivers and provide preliminary insight into possible contributing factors. Methods Carers of individuals with DCM completed a Web-based survey hosted by Myelopathy.org, an international DCM charity. Carer quality of life was assessed in the form of caregiver happiness and 7 dimensions of carer burden using the Care-Related Quality of Life (CarerQol) instrument. The relationships between patient disease severity, patient pain, and carer quality of life were investigated. Differences in carer quality of life were assessed across patient and carer demographic groups, including between UK and US carers. Results DCM caregivers experienced substantial burden as a result of their caregiving (mean CarerQol-7D=64.1; 95% CI 58.8-69.5) and low happiness (mean CarerQol-VAS [Visual Analog Scale]=6.3; 95% CI 5.7-6.9). Burden was high and happiness was low in DCM carers when compared with a large, mixed-disease study of adult informal carers where CarerQol-7D was 79.1 and CarerQol-VAS was 7.1. No significant relationship was found between DCM carer quality of life and patient disease severity and pain scores. DCM carer quality of life appeared uniform across all patient and carer demographic groups. Conclusions Caring for individuals with DCM is associated with reduced quality of life in the form of significant burden and reduced happiness. Reductions appear greater in DCM than in other diseases investigated. However, no simple relationship was identified between individual patient or carer factors and carer quality of life.

Abstract
OBJECTIVE To identify and reveal the sensitivity and efficiency of dynamic somatosensory evoked potentials (DSSEPs) in the diagnosis of cervical spondylotic myelopathy (CSM). METHODS This retrospective study included 31 CSM and 15 control patients. All patients received SSEP examination with stimulation of median and ulnar nerves at neutral, flexed, and extended cervical positions; latency and amplitude were recorded at the C2 and C5 spinous processes and in the scalp over the primary sensory area (C3'/4'). The percentage changes in latency and amplitude with dynamic motion were examined for each lead and compared between groups; the diagnostic cutoff values were determined using receiver operating characteristic curve analysis. RESULTS All the patients with CSM received surgeries and were followed up for 1 year. Amplitude parameters varied with a dynamic position in both groups; all recorded dynamic SSEP indices except right median stimulus recorded at C5 spinous process, right ulnar stimulus recorded at scalp point C3, and right ulnar stimulus recorded at C2 spinous process were significantly different between groups (P < 0.05), but latency was not (P > 0.05). At the neutral position, the amplitude of left media stimulus recorded at C2 spinous process (LMC2) was associated with CSM, but with low diagnostic accuracy (area under the curve = 0.199). At a dynamic position, the percentage change in amplitude of LMC2 and of left ulnar stimulus recorded at C2 spinous process (LUC2) were determined to be diagnostic of CSM (P < 0.05), with areas under the curve of 0.891 and 0.912, respectively. Both records had high sensitivity and specificity in the diagnosis of CSM; the diagnostic cutoff values of LMC2 and LUC2 were calculated as 10.2% and 19.25%, respectively. CONCLUSIONS The percentage change in amplitude was obvious during cervical dynamic motion, with records from LMC2 and LUC2 being predictive of CSM diagnosis; dynamic SSEPs provided a simple, accurate, and noninvasive supplementary test for the diagnosis of complicated CSM.

Abstract
STUDY DESIGN Retrospective study using prospectively collected registry data. OBJECTIVE The authors examine the influence of preoperative mental health on outcomes after anterior cervical discectomy and fusion (ACDF) and determine the impact of ACDF on postoperative mental health. SUMMARY OF BACKGROUND DATA While studies have reported a negative correlation between preoperative mental health and outcomes following lumbar spine surgery, the influence on outcomes following cervical spine surgery remains relatively understudied. METHODS Prospectively collected registry data of 104 patients who underwent single-level ACDF for cervical spondylotic myelopathy were reviewed. Patients were dichotomized into top and bottom halves based on preoperative SF-36 MCS (Mental Component Summary) using a cutoff of 48. Outcomes assessed were visual analogue scale for neck pain, arm pain, AAOS Neck Pain and Disability, Neurogenic Symptoms, Neck Disability Index, Short-Form 36, Japanese Orthopaedic Association myelopathy score, return to work, return to function, satisfaction and expectation fulfilment up to 2 years postoperatively. RESULTS The preoperative MCS was 37.5 ± 8.1 and 57.4 ± 6.3 in the Low and High MCS groups respectively (P < 0.001). The Low MCS group had poorer preoperative scores (P < 0.05). There was no significant difference in length of stay or comorbidities (P > 0.05). The High MCS group had less neck pain (P = 0.002) and showed a trend towards lower Neck Disability Index (P = 0.062) at 2 years. The Low MCS group demonstrated greater improvement in Japanese Orthopaedic Association (P = 0.007) and similar improvement in other scores (P > 0.05). There was no significant difference in proportion that achieved minimal clinically important difference for each score (P > 0.05). Both groups had similar rates of return to work, return to function, expectation fulfilment, and satisfaction (P > 0.05). Lower preoperative MCS was predictive of greater improvement in MCS (r = -0.477, P < 0.001). CONCLUSION Despite relatively greater pain and disability at 2 years, patients with poor baseline mental health experienced similar improvement in clinical outcomes, return to work, and satisfaction rates.

Abstract
Objective: Depression is a psychiatric disorder associated with poorer health outcomes. Inappropriate mechanical stress and aging are factors associated with developing cervical spondylosis. The connection between cervical spondylosis and depression is not developed. Methods: From the health insurance claims data of Taiwan, we identified 34,166 persons newly diagnosed with depression in 2000⁻2010 and 34,166 persons without the disorder frequency matched by sex, age and diagnosis year. Both cohorts were followed up to the end of 2013 to estimate incident cervical spondylosis. We further examined the risk of cervical spondylosis in depressed people taking antidepressants. Results: The incidence of cervical spondylosis was 1.8-fold greater in the depression cohort than in comparison cohort (9.46 vs. 5.36 per 1000 person-years), with an adjusted hazard ratio (aHR) of 1.79 (95% confidence interval (CI) = 1.66⁻1.92). The incidence of cervical spondylosis increased in patients who had taken medications of serotonin-specific reuptake inhibitors (SSRIs) or of non-SSRIs than in those without these medicines (9.13 or 11.5 vs. 6.54 per 1000 person-years, respectively). Conclusions: Patients with depression are at an increased risk of developing cervical spondylosis. Additional efforts in reducing the risk of cervical spondylosis might be required in depressed individuals undergoing anti-depressive therapy.

Abstract
BACKGROUND Cervical spondylosis adversely affects life quality for its heavy disease burden. The report on the community-based prevalence and associated factors of cervical spondylosis is rare, especially in Chinese population. Whether prevention is needed and how to prevent it is not clear. This study aims to explore its prevalence and related lifestyle factors and provide evidence on prevention of cervical spondylosis. METHODS A community-based multistage cross-sectional survey of six communities from the Chinese population was conducted. A face-to-face interview was conducted to obtain individual information, and prevalence was calculated. Single-factor analysis and multivariable logistic regressions were used to explore the associated factors in total and subgroup populations. RESULTS A total of 3859 adults were analyzed. The prevalence of cervical spondylosis was 13.76%, although it differed significantly among the urban, suburban, and rural populations (13.07%, 15.97%, and 12.25%, respectively). Moreover, it was higher in females than in males (16.51% vs 10.49%). The prevalence among different age groups had an inverted U shape. The highest prevalence was in the age group from 45 to 60 years old. The associated factors differed by subgroups. There were positive associations between engaging in mental work, high housework intensity, and sleep duration of less than 7 h/day with cervical spondylosis. Going to work on foot was a negative factor of cervical spondylosis in the total population. For people aged less than 30 years, keeping the same work posture for 1-2.9 h/day was a special related factor. Exposure to vibration was an associated factor for females aged 45-60 years. Menopause was a special related factor for women. CONCLUSIONS Prevalence of cervical spondylosis was high in Chinese population. People younger than 60 years were the focus of prevention for cervical spondylosis. Moreover, the characters between male and female and among different age groups were different and required targeted interventions.

Abstract
OBJECTIVEDepression and anxiety have been demonstrated to have negative impacts on outcomes after spine surgery. In patients with cervical deformity (CD), the psychological and physiological burdens of the disease may overlap without clear boundaries. While surgery has a proven record of bringing about significant pain relief and decreased disability, the impact of depression and anxiety on recovery from cervical deformity corrective surgery has not been previously reported on in the literature. The purpose of the present study was to determine the effect of depression and anxiety on patients’ recovery from and improvement after CD surgery.METHODSThe authors conducted a retrospective review of a prospective, multicenter CD database. Patients with a history of clinical depression, in addition to those with current self-reported anxiety or depression, were defined as depressed (D group). The D group was compared with nondepressed patients (ND group) with a similar baseline deformity determined by propensity score matching of the cervical sagittal vertical axis (cSVA). Baseline demographic, comorbidity, clinical, and radiographic data were compared among patients using t-tests. Improvement of symptoms was recorded at 3 months, 6 months, and 1 year postoperatively. All health-related quality of life (HRQOL) scores collected at these follow-up time points were compared using t-tests.RESULTSSixty-six patients were matched for baseline radiographic parameters: 33 with a history of depression and/or current depression, and 33 without. Depressed patients had similar age, sex, race, and radiographic alignment: cSVA, T-1 slope minus C2–7 lordosis, SVA, and T-1 pelvic angle (p > 0.05). Compared with nondepressed individuals, depressed patients had a higher incidence of osteoporosis (21.2% vs 3.2%, p = 0.028), rheumatoid arthritis (18.2% vs 3.2%, p = 0.012), and connective tissue disorders (18.2% vs 3.2%, p = 0.012). At baseline, the D group had greater neck pain (7.9 of 10 vs 6.6 on a Numeric Rating Scale [NRS], p = 0.015), lower mean EQ-5D scores (68.9 vs 74.7, p < 0.001), but similar Neck Disability Index (NDI) scores (57.5 vs 49.9, p = 0.063) and myelopathy scores (13.4 vs 13.9, p = 0.546). Surgeries performed in either group were similar in terms of number of levels fused, osteotomies performed, and correction achieved (baseline to 3-month measurements) (p < 0.05). At 3 months, EQ-5D scores remained lower in the D group (74.0 vs 78.2, p = 0.044), and NDI scores were similar (48.5 vs 39.0, p = 0.053). However, neck pain improved in the D group (NRS score of 5.0 vs 4.3, p = 0.331), and modified Japanese Orthopaedic Association (mJOA) scores remained similar (14.2 vs 15.0, p = 0.211). At 6 months and 1 year, all HRQOL scores were similar between the 2 cohorts. One-year measurements were as follows: NDI 39.7 vs 40.7 (p = 0.878), NRS neck pain score of 4.1 vs 5.0 (p = 0.326), EQ-5D score of 77.1 vs 78.2 (p = 0.646), and mJOA score of 14.0 vs 14.2 (p = 0.835). Anxiety/depression levels reported on the EQ-5D scale were significantly higher in the depressed cohort at baseline, 3 months, and 6 months (all p < 0.05), but were similar between groups at 1 year postoperatively (1.72 vs 1.53, p = 0.416).CONCLUSIONSClinical depression was observed in many of the study patients with CD. After matching for baseline deformity, depression symptomology resulted in worse baseline EQ-5D and pain scores. Despite these baseline differences, both cohorts achieved similar results in all HRQOL assessments 6 months and 1 year postoperatively, demonstrating no clinical impact of depression on recovery up until 1 year after CD surgery. Thus, a history of depression does not appear to have an impact on recovery from CD surgery.

Abstract
BACKGROUND Anterior cervical discectomy and fusion (ACDF) is a commonly performed procedure for patients with symptomatic degenerative conditions of the cervical spine. The objective is to assess the impact of preoperative depression and other baseline characteristics on patient reported clinical outcomes following ACDF surgery based on the experience at our institution. METHODS This was a retrospective cohort study of some patients undergoing ACDF at a single institution from 2012 to 2014. Ninety-three patients that underwent an ACDF procedure were included. The primary outcome measure was post-operative Nurick score. RESULTS Sixteen (17.2%) patients had a formal diagnosis of depression compared to 77 (82.8%) patients without depression. On univariate analysis, patients with depression had statistically significantly higher Nurick scores compared to patients without depression after surgery (coefficient =0.55, 95% CI: 0.21-0.90, P=0.002). On multivariate analysis, there was a trend toward higher postoperative Nurick scores in patients that had depression (coefficient =0.31, 95% CI: -0.01-0.63, P=0.057). CONCLUSIONS This small retrospective study reveals an inverse relationship between preoperative depression and functional outcome. Further research should be performed to investigate this relationship and to investigate if treating depression can improve postoperative outcomes.

Abstract
BACKGROUND Depression has been associated with inferior outcomes following lumbar spine surgery. Our purpose was to investigate the prevalence of depression and its impact on the outcomes of a large sample of cervical disc arthroplasty patients and to examine the change in depression occurring in conjunction with changes in disability and pain. METHODS A cohort of 271 patients who underwent single or multi-level cervical disc arthroplasty at a single orthopedic center filled out the Neck Disability Index, Medical Outcomes Study SF-36, numerical rating scales for neck pain and arm pain, preoperatively and 12-month postoperatively. Patients were classified as Depressed or Non-Depressed, based on their preoperative SF-36 Mental Component Summary (MCS) score. Preoperative scores, 12-month postoperative scores, and change in scores (adjusted for preoperative scores, smoking status, and strenuous job) were compared between Depressed and Non-Depressed. Next, patients in the 2 groups were subdivided into 4 groups: Always Depressed, Never Depressed, No Longer Depressed, and Newly Depressed, based on their combined preoperative and postoperative MCS scores. The same score comparisons were conducted among the 4 groups. RESULTS Forty-four percent (118 of 271) of the patients in our sample were Depressed. Despite a significant improvement after surgery, Depressed patients had poorer pre- and postoperative scores than Non-Depressed patients for NDI, MCS, neck pain and arm pain. Two-thirds (80 of 118) of the Depressed patients were No Longer Depressed at 12 months and had postoperative scores similar to the Never Depressed patients. Eight percent (12 of 153) of the Non-Depressed patients became Newly Depressed by 12 months and had postoperative scores similar to the Always Depressed patients. CONCLUSIONS Depression is a common occurrence in patients with cervical disorders. Relief from pain and disability after cervical disc arthroplasty can be associated with relief from depression, but poor outcomes may also result in patients becoming depressed.

Abstract
BACKGROUND CONTEXT Posterior cervical fusion (PCF) has been shown to be an effective treatment for cervical spondylosis, but is associated with a 9% complication rate and high costs. To limit such complications and costs, it is imperative that proper selection of surgical candidates occur for those most likely to do well with the surgery. Affective disorders, such as depression, are associated with worsened outcomes after lumbar surgery; however, this effect has not been evaluated in patients undergoing cervical spine surgery. PURPOSE To assess the predictive value of preoperative depression and the health state on 1-year quality of life (QOL) outcomes after PCF. STUDY DESIGN A retrospective cohort analysis. PATIENT SAMPLE Eighty-eight patients who underwent PCF for cervical spondylosis were reviewed. OUTCOME MEASURES Preoperative and 1-year postoperative health outcomes were assessed based on the Pain Disability Questionnaire (PDQ), the Patient Health Questionnaire-9 (PHQ-9), and the EuroQol five-dimensions (EQ-5D) questionnaire. METHODS Univariable and multivariable regression analyses were performed to assess for preoperative predictors of 1-year change in health status. RESULTS Compared with preoperative health states, the PCF cohort showed statistically significant improved PDQ (87.8 vs. 73.6), PHQ-9 (7.7 vs. 6.6), and EQ-5D (0.50 vs. 0.60) scores at 1 year postoperatively. Only 10/88 (11%) patients achieved or surpassed the minimum clinically important difference for the PHQ-9 (5). Multiple linear and logistic regression analyses showed that increasing PHQ-9 and EQ-5D preoperative scores were associated with reduced 1-year postoperative improvement in health status (EQ-5D index). CONCLUSIONS Of patients who undergo PCF, those with a greater degree of preoperative depression have lower improvements in postoperative QOL compared with those with less depression. Additionally, patients with better preoperative health states also attain lower 1-year QOL improvements.

Abstract
STUDY DESIGN Cross-sectional analysis of patients' expectations of cervical spine surgery using the Hospital for Special Surgery Cervical Spine Surgery Expectations Survey (Expectations Survey). OBJECTIVE To preoperatively describe patients' long-term expectations of surgery in terms of demographic, clinical, and psychological characteristics. SUMMARY OF BACKGROUND DATA Although important components of patient-centered care, few studies have systematically considered patients' expectations of cervical spine surgery. METHODS Several days before surgery, 150 patients completed the Expectations Survey, which is composed of 20 physical and psychological items; scores range from 0 to 100, and higher scores reflect choosing more items and more improvement (i.e., more expectations). Patients completed additional questionnaires addressing demographic, psychological, and clinical status, including disability due to pain with the Neck Disability Index (NDI) and overall physical and mental health with the 12-item Short Form Health Survey. RESULTS Mean age was 54 years, and 61% were males. The most commonly chosen items were relieve neck (87%) and upper extremity (85%) pain, stop the spine condition from getting worse (97%), and remove the control the spine condition had on life (96%). Twenty-three percent of patients chose all 20 items, 39% chose 16 to 19 items, and 38% chose 15 or fewer items. In multivariate analysis, patients were more likely to choose more items if they were younger (odds ratio [OR] = 2.2; 95% confidence interval [CI], 1.2-4.0; P = 0.01), had worse NDI scores (OR = 6.5; 95% CI, 3.2-13.2; P < 0.0001), and had worse SF-12 Physical (OR = 1.9; 95% CI, 1.0-3.6; P = 0.05) and Mental Health scores (OR = 2.0; 95% CI, 1.1-3.6; P = 0.02). The Expectations Survey scores ranged from 10 to 100, and the mean score was 65 ± 24. In multivariate analysis, patients were more likely to have higher scores if they were younger (OR = 2.8; 95% CI, 1.4-6.0; P = 0.006) and had worse NDI scores (OR = 6.0; 95% CI, 2.8-13.2; P < 0.0001). CONCLUSION Multiple clinical variables were associated with expectations, with younger age and more disability due to pain being the most consistently associated with more expectations. LEVEL OF EVIDENCE 3.

Abstract
Object
Skull base chordomas can be managed by surgical intervention and adjuvant radiotherapy. As survival for this disease increases, identification of determinants of quality of life becomes an important focus for guiding comprehensive patient care. In this study the authors sought to measure functional outcome and quality of life in patients with skull base chordomas and to identify determinants of quality of life in these patients.
Methods
The authors carried out an internet-based cross-sectional survey, collecting detailed data for 83 individual patients. Demographic and clinical variables were evaluated. Functional outcomes were determined by Karnofsky Performance Scale (KPS) and Glasgow Outcome Scale Extended (GOSE), quality of life was measured using the 36-Item Short Form Health Survey (SF-36), and depression was assessed using Patient Health Questions–9 (PHQ-9) instrument. Caregiver burden was assessed using the Zarit Burden Interview (ZBI). Univariate and multivariate analysis was performed to identify determinants of the physical and mental components of the SF-36.
Results
Patients with skull base chordomas who have undergone surgery and/or radiation treatment had a median KPS score of 90 (range 10–100, IQR 10) and a median GOSE score of 8 (range 2–8, IQR 3). The mean SF-36 Physical Component Summary score (± SD) was 43.6 ± 11.8, the mean Mental Component Summary score was 44.2 ±12.6, and both were significantly lower than norms for the general US population (p < 0.001). The median PHQ-9 score was 5 (range 0–27, IQR 8). A PHQ-9 score of 10 or greater, indicating moderate to severe depression, was observed in 29% of patients. The median ZBI score was 12 (range 0–27, IQR 11), indicating a low burden. Neurological deficit, use of pain medication, and requirement for corticosteroids were found to be associated with worse SF-36 Physical Component Summary score, while higher levels of depression (higher PHQ-9 score) correlated with worse SF-36 Mental Component Summary score.
Conclusions
Patients with skull base chordomas have a lower quality of life than the general US population. The most significant determinants of quality of life in the posttreatment phase in this patient population were neurological deficits (sensory deficit and bowel/bladder dysfunction), pain medication use, corticosteroid use, and levels of depression as scored by PHQ-9.

Abstract
PURPOSE The Myelopathy Disability Index and the Neck Disability Index are widely used to assess outcome in cervical spine surgery. Short Form (SF) 36 is a generic measure of health which can be used to measure health gains across a wide variety of conditions. The aim of the current study is to assess long-term outcomes using these measures in a cohort of patients with cervical spondylotic myelopathy (CSM). METHODS Cohort study with prospective data collection. Patients with CSM being offered decompressive surgery were asked to complete a set of generic and condition-specific outcome measures. This was repeated post-operatively at 3, 12, 24 and 60 months. SF-36 was used as a generic outcome measure and the Myelopathy Index, Neck Disability Score and visual analogue scores for arm, neck and hand pain, paraesthesia and dysthaesia were used as condition-specific outcome measures. RESULTS Significant improvements in all outcome measures were seen in 70% of the cohort. For SF-36, pre-operative scores were lower than age-matched controls in all domains and significant improvements were seen 3 months following surgery. This improvement in outcome was maintained at 5 years follow-up in approximately two-thirds of those with initial improvement. CONCLUSION We have used generic and condition-specific outcome measures of health and shown that in patients with CSM treated surgically, up to 70% can expect improvement in their quality of life. These outcome measures are easy to collect and provide objective evidence of changes in quality of life and disability and can help quantify the potential health gains that can be achieved.

Abstract
Cervical spondylosis is a broad term which describes the age related chronic disc degeneration, which can also affect the cervical vertebrae, the facet and other joints and their associated soft tissue supports. Evidence of spondylitic change is frequently found in many asymptomatic adults. Radiculopathy is a result of intervertebral foramina narrowing. Narrowing of the spinal canal can result in spinal cord compression, ultimately resulting in cervical spondylosis myelopathy. This review article examines the current literature in relation to the cervical spondylosis and describes the three clinical syndromes of axial neck pain, cervical radiculopathy and cervical myelopathy

Abstract
Object
The primary purpose of this study was to analyze what effect preoperative patient expectations and 36-Item Short Form Health Survey (SF-36) Mental Component Summary (MCS) scores have on clinical outcomes. To the authors' knowledge, there are no prospective studies that have examined the effects of both preoperative pain expectations and SF-36 MCS scores on clinical outcomes and satisfaction with results following anterior cervical discectomy and fusion (ACDF).
Methods
This study analyzed 79 patients (38 men, 41 women) undergoing 1- to 3-level ACDF surgery. Preoperatively, patients were divided into 2 groups for the expectation analyses: patients who expected complete resolution of pain postoperatively (44 total) and those who expected some residual pain (35 total) postoperatively. Preoperative SF-36 MCS scores were used to test the possible effects of mental health on clinical outcomes and satisfaction. Clinical outcomes were evaluated using visual analog scales (VASs) for neck/arm pain, Neck Disability Index (NDI), SF-36 Physical Component Summary (PCS)/MCS, and patient satisfaction with results scales. The mean follow-up duration was 38.8 months (range 7–59 months).
Results
All postoperative measures depicted significant improvement overall. Patients who expected no pain reported lower postoperative neck/arm pain scores (p < 0.02), higher SF-36 MCS scores (p = 0.04), and higher satisfaction with results scores (p = 0.01) compared with patients who expected some pain, after controlling for their respective preoperative scores. Higher preoperative SF-36 MCS scores predicted significantly lower postoperative neck pain (p = 0.003) and NDI (p = 0.004) scores, as well as higher postoperative SF-36 PCS (p = 0.002), SF-36 MCS (p = 0.001), and satisfaction (p = 0.03) scores, after controlling for their respective preoperative scores.
Conclusions
Patients who expected no pain postoperatively reported better scores on the nonstandardized outcome measure scales (VAS arm/neck, satisfaction with results), and higher SF-36 MCS scores. Higher preoperative MCS scores were related to better overall (standardized and nonstandardized) clinical outcomes (VAS neck, NDI, SF-36 PCS/MCS, and satisfaction with results). The results suggest that optimism in patients' expectations as well as mental well-being are related to improved clinical outcomes and higher patient satisfaction.

Abstract
OBJECT In this study, the authors assessed the construct validity and the reliability of the World Health Organization Quality of Life-Bref (WHOQOL-Bref) questionnaire in patients with cervical spondylotic myelopathy (CSM) and compared the performance of the WHOQOL-Bref and the 36-Item Short Form Health Survey (SF-36) in assessing quality of life (QOL) in patients with CSM. METHODS In this prospective study, 70 patients with CSM were assessed preoperatively and again 1 year after central corpectomy using the Nurick scale, the SF-36, and the WHOQOL-Bref. Construct validity and reliability of the WHOQOL-Bref, its responsiveness compared with that of the SF-36, and the correlations between the 2 scales were studied. RESULTS The WHOQOL-Bref was found to be valid (p < 0.001, Cuzick test for trend between the physical domain of the WHOQOL-Bref and Nurick grade) and reliable (Cronbach alpha > 0.7). It had smaller floor and ceiling effects (ranges 1.4-7.1% and 0-7.1%, respectively) than the SF-36 (ranges 2.9-71.4% and 0-14.1%, respectively). There was significant postoperative improvement in patient scores on all the SF-36 scales (p < 0.001) and the physical, psychological, and environment domains of the WHOQOL-Bref (p < 0.001). The SF-36 scales were more responsive to change (relative efficiency range 0.24-1) than the WHOQOL-Bref domains (relative efficiency range 0.002-0.73). Among scales measuring similar concepts, only the physical functioning and bodily pain scales of the SF-36 had a moderate correlation (r = 0.57 and 0.53, respectively; p < 0.001) with the physical domain of WHOQOL-Bref. Many of the scales of these 2 QOL instruments unexpectedly had a fair correlation with one another (r range = 0.2-0.4). CONCLUSIONS The WHOQOL-Bref, like the SF-36, is valid and reliable in assessing outcome in patients with CSM. It measures impairment in CSM in a more uniform manner than the SF-36, but its domains are less responsive to postoperative changes. Because the WHOQOL-Bref measures different constructs and has additive value, it should be used along with the SF-36 for QOL assessment in patients with CSM.

Abstract
STUDY DESIGN Community cross-sectional self-report survey of adults with spinal cord injury (SCI). OBJECTIVES The aim of this study was to examine the likelihood of depression, anxiety and stress in adults with non-traumatic SCI (NT-SCI) compared with adults with traumatic SCI (T-SCI). SETTING Victoria, Australia. Adults (N=443; NT-SCI n=62) living in the community and attending specialist SCI rehabilitation clinics. METHODS Participants completed a self-report survey by internet, telephone or hard copy. Items included demographic and injury-related characteristics and the short form Depression, Anxiety and Stress Scale (DASS-21). RESULTS Persons with NT-SCI were significantly more likely to be female (P<0.05), older (P<0.001) and have lower-level incomplete injuries (P<0.001). The probability of depression, anxiety or stress in respondents with NT-SCI did not differ from persons with T-SCI (P>0.05). Overall, the prevalence of adverse mental health problems defined by scoring above DASS-21 cutoffs, were depression 37%, anxiety 30%, and clinically significant stress 25%. CONCLUSIONS This study examined multiple mental health outcomes after NT-SCI in Australia. This study provides some evidence that the results of studies of depression, anxiety or stress in persons with T-SCI can be generalised to those with NT-SCI in the post-acute phase. NT-SCI patients are also at substantial risk of poor mental health outcomes. General demographic and injury-related characteristics do not seem to be important factors associated with the mental health of adults with SCI whether the SCI is traumatic or non-traumatic in origin.

Abstract
OBJECTIVE There is little information about in-hospital complication rates, adverse outcomes, and mortality after spinal fusion for cervical spondylotic myelopathy (CSM). The aim of this study was to report inpatient mortality, complications, and outcomes on a national level. METHODS We used the National Inpatient Sample to identify 58,115 admissions of patients with CSM who underwent spinal fusion in the United States from 1993 to 2002. Multivariate analysis was performed to analyze the effects of patient and hospital characteristics on outcomes such as mortality, complications, discharge disposition, and length of stay. RESULTS A total of 58,115 patients with CSM underwent spinal fusion with an average mortality rate of 0.6%, a complication rate of 13.4%, and a mean length of stay of 4 days. Pulmonary (3.6%) and postoperative hemorrhages or hematomas (2.3%) were the most common complications reported. One postoperative complication led to a 4-day increase in mean length of stay, increased the mortality rate 20-fold, and added more than $10,000 to hospital charges. Multivariate analysis identified age, comorbidity, and admission type as the main predictors of mortality, complication rate, and adverse outcome. Patients aged > or =85 or 65 to 84 years had respective 44- and 14-fold increases in mortality, compared with patients in the 18- to 44-year age group. Patients older than 84 years had a 40-fold increase in adverse outcomes and a 5-fold likelihood of medical complications. Patients with three or more comorbidities had an increased risk of medical complications (odds ratio [OR], 1.98), adverse discharge (OR, 2.17), and in-hospital mortality (OR, 2.36). Elective admissions were associated with much lower rates of mortality (OR, 0.28), complication (OR, 0.68), and adverse outcome (OR, 0.26). Complications were greater for posterior fusion (16.4%) versus anterior fusion (11.9%) procedures. Anterior fusions were associated with a greater incidence of dysphagia (3%) and hoarseness (0.21%). Cervical spondylosis patients who presented without myelopathy had a much lower incidence of complications (6.3%). CONCLUSIONS We provide a national estimate of inpatient complications and outcomes after spinal fusion for CSM patients in the United States. We demonstrate the impacts of age, complications, and medical comorbidities on the outcome of surgery for patients with this common disorder. We provide complication rates stratified by age and medical comorbidities for elderly patients who present with CSM who need spinal fusion.

Abstract
STUDY DESIGN Preoperative somatosensory-evoked potentials (SEPs) were retrospectively analyzed and classified, and compared with surgical outcome. OBJECTIVE To evaluate the value of the preoperative SEP waveform in predicting the clinical outcome after surgical management of cervical spondylotic myelopathy (CSM). SUMMARY OF BACKGROUND DATA SEPs have played an important role in spinal surgery. However, the value of SEPs in predicting the outcome of surgery for CSM remains controversial. METHODS This study enrolled 76 CSM patients who underwent surgical intervention. Median nerve SEPs were recorded before surgery. The Japanese Orthopedic Association (JOA) scoring system was used to evaluate the neurologic function before surgery and at postoperative follow-up at 1, 3, 6, 12, and 24 months. Patients were divided into 5 groups according to the classification of their preoperative SEP waveforms. Group I patients had normal SEPs, group IIa had normal latency and abnormal amplitude, group IIb had abnormal latency and normal amplitude, group III had abnormal latency and amplitude, and group IV had immeasurable waveforms. The myelopathic disability scores and surgical outcomes in different groups were compared by the Kruskal-Wallis test. RESULTS The SEP classification was found to be significantly associated with the JOA score (Pearson's chi test, chi = 53.9, P < 0.05). There were no significant differences in JOA score recovery at different follow-up times within any SEP group. At 24 months after surgery, there was no significant difference in the recovery ratio between groups I and IIa, or between groups IIb and III (Kruskal-Wallis test, P > 0.05). However, the recovery ratio was significantly higher in groups I and IIa than in all the other groups (Kruskal-Wallis test, P < 0.05), and in groups IIb and III than in group IV (Kruskal-Wallis test, P < 0.05). CONCLUSION SEP classification correlates well with CSM disability and postoperative recovery ratio. Median nerve SEP recordings would be a valuable and practical tool for the diagnosis and prognosis of myelopathy.

Abstract
The study aims to develop and assess metric proprieties of the Portuguese version of the Hospital Anxiety and Depression Scale. A sequential sample includes 1322 participants diagnosed with cancer, stroke, epilepsy, coronary heart disease, diabetes, myotonic dystrophy, obstructive sleep apnoea, depression and a non-disease group, which completed the HADS. The first step includes translation, retroversion, inspection for lexical equivalence and content validity, and cognitive debriefing. Then we reproduce oblique exploratory factor analysis and use confirmatory factor analysis. We explore the sensibility of the questionnaire. The validation process of the Portuguese HADS version shows metric properties similar to those in international studies, suggesting that it measures the same constructs, in the same way, as the original HADS form.
