Abstract
PURPOSE To investigate the role of depressive symptoms on clinical outcomes in patients undergoing spinal surgery up to 2-year follow-up. METHODS The study used data from an institutional spine surgery registry (January 2016, through March 2022) to identify patients (> 18 years) undergoing spine surgery. Patients with Oswestry Disability Index (ODI) < 20/100 at baseline or undergoing surgery on the cervical spine or for idiopathic spinal deformity and trauma patients were excluded. The patients were divided into two groups based on the pre-operative Mental Component Summary (MCS) score of the SF-36: depression group (MCS ≤ 35) or non-depression group (MCS > 35). The ODI and MCS scores trajectory were wined over the 24-month post-surgery between groups. Additionally, a secondary subgroup analysis was conducted comparing outcomes between those with depressive symptoms (persistent-depression subgroup) and those without depressive symptoms (never-depression subgroup) at 3 months after surgery. RESULTS A total of 2164 patients who underwent spine surgery were included. The pre-operative depression group reported higher ODI total scores and lower MCS than the pre-operative non-depression group at all time points (P < 0.001). The persistent-depression subgroup reported higher ODI total scores and lower MCS than the never-depression subgroup at all follow-ups (P < 0.001). CONCLUSION Functional disability and mental health status improve in patients with depression symptoms undergoing spinal surgery. Despite this improvement, they do not reach the values of non-depressed subjects. Over the 2-year follow-up time, patients with depression show a different trajectory of ODI and MCS. Caregivers should be aware of these results to counsel patients with depression symptoms.

Abstract
The literature has clearly stressed that patients suffering from chronic pain are at high risk of suicidal behavior (SB). Hence the need to improve the characterization of this behavior risk profile in these patients. Some findings indicate a possible relationship between demoralization and pain, with functional disability found to be correlated with demoralization. The primary objective of this study was to investigate the relationship between demoralization and suicidal ideation (SI) in patients with chronic pain. The secondary objective was to verify whether demoralization can occur independently of depression in these patients. Inclusion criteria were patients with chronic pain, with SI or not, matched for age and gender, aged > 18 years. Seventy patients with SI and 70 patients without SI were included. Between-group difference was statistically significant (F=1.064; t= 7.21, p<0.001, d=1.22), confirming the presence of numerous and intense depressive symptoms in the patients of the SI group. Regarding the Demoralization Scale (DS), the difference between the two groups was statistically highly significant (F=1.49; t=9.44; p<0.001, d=1.6). There was also a strong positive correlation between DS and Beck Depression Inventory (BDI-II) (R=0.749; p<0.001 for the study group and R=0.704; p<0.001 for the control group). Furthermore, there was a strong positive correlation between the DS and the Scale for Suicide Ideation (SSI) in the SI patients group, meaning that high demoralization is associated with higher suicidal ideation as well. Our findings did not allow us to distinguish between the notions of depression and demoralization, since the two constructs show almost the same strong positive correlation with suicidal thoughts, the two also being strongly correlated with each other.

The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) Comparison Study: Assessing for PROMIS-29 Depression and Anxiety Psychopathologic Cutoff Values Amongst Patients Undergoing Elective Complex Spine Procedures. World Neurosurg 2022; 164:e908-e914.

Abstract
OBJECTIVE The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and the Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) are used to assess patient psychology, pain, and quality of life. As psychological factors, such as depression and anxiety, are associated with poor perioperative outcomes, we aim to translate MMPI-2-RF values to PROMIS-29 scores and establish cutoff values for PROMIS-29 anxiety and depression domains that might warrant attention preoperatively. METHODS Seventy adult patients scheduled for an elective spinal surgery between July 2018 and February 2020 who completed both the MMPI-2-RF and PROMIS-29 preoperatively at a single institution were reviewed. RESULTS Patients with MMPI-2-RF scores of 65 or greater (the cutoff for psychopathology) in the emotional/internalizing dysfunction scale (4.29%) had an average PROMIS-29 depression score of 14.33, which is significantly higher than the control group's (<65 score) 8.49 score (P = 0.04). Similarly, those demonstrating psychopathology on the demoralization (4.29%) and helplessness/hopelessness (4.29%) scales had average PROMIS-29 depression scores significantly higher than the control group's averages (15.33 vs. 8.45, P = 0.02 and 14.33 vs. 8.49, P = 0.04, respectively). Patients with an MMPI-2-RF score of 65 or greater on the emotional/internalizing dysfunction (4.29%), stress/worry (10.00%), and anxiety (7.14%) scales had average PROMIS-29 anxiety domain scores of 15, 15, and 15, respectively, which were significantly greater than that of the control group's scores (8.94, P = 0.04; 8.75, P = 0.004; and 8.55, P < 0.001, respectively). CONCLUSIONS PROMIS-29 scores of 15 or greater on the depression and anxiety domains may have psychopathologies that warrant addressing, given their increased likelihood of having poor outcomes.

Abstract
STUDY DESIGN A prospective cohort study. OBJECTIVE To assess the relationship of fear avoidance and demoralization on gait and balance and determine a threshold score for the Tampa Scale for Kinesophobia (TSK) and the Demoralization Scale (DS) that identifies spine patients with gait and balance dysfunction amplified by underlying psychological factors. SUMMARY OF BACKGROUND DATA Fear avoidance and demoralization are crucial components of mental health that impact the outcomes in spine surgery. However, interpreting their effect on patient function remains challenging. Further establishing this correlation and identifying a threshold of severity can aid in identifying patients in whom a portion of their altered gait and balance may be amplified by underlying psychologic distress. METHODS Four hundred five symptomatic spine patients were given the TSK and DS questionnaires. Patient's gait and balance were tested with a human motion capture system. A TSK score of 41 and a DS score of 30 were chosen as thresholds to classify moderate versus severe dysfunction based on literature and statistical analysis. RESULTS Higher TSK and DS scores were correlated with worse walking speed (P < 0.001), longer stride time (P = 0.001), decreased stride length (P < 0.048), and wider step width (<0.001) during gait as well as increased sway across planes (P = 0.001) during standing balance. When classified by TSK scores >41, patients with more severe fear avoidance had slower walking speed (P < 0.001), longer stride time (P = 0.001), shorter stride length (P = 0.004), increased step width (P < 0.001), and increased sway (P = 0.001) compared with their lower scoring counterparts. Similarly, patients with DS > 30 had slower walking speed (P = 0.012), longer stride time (P = 0.022), and increased sway (P = 0.003) compared with their lower scoring counterparts. CONCLUSION This study demonstrates that fear avoidance and demoralization directly correlate with worsening gait and balance. Furthermore, patients with TSK > 41 and DS > 30 have more underlying psychological factors that contribute to significantly worse function compared with lower scoring peers. Understanding this relationship and using these guidelines can help identify and treat patients whose gait dysfunction may be amplified by psychologic distress.Level of Evidence: 3.

The Role of Demoralization and Meaning in Life (DEMIL) in Influencing Suicidal Ideation Among Patients Affected by Chronic Pain: Protocol of a Single-Center, Observational, Case-Control Study. JMIR Res Protoc 2020; 9:e24882. [PMID: 33144275 PMCID: PMC7728536 DOI: 10.2196/24882] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 11/03/2020] [Accepted: 11/03/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Chronic pain is a significant risk factor for suicidal ideation (SI) and suicidal behavior (SB), including a 20%-40% prevalence rate of SI, a prevalence between 5% and 14% of suicide attempts, and a doubled risk of death by suicide in patients with chronic pain compared to controls. In most studies, associations between chronic pain and suicidality are robust, even after adjusting for the effect of sociodemographics and psychiatric comorbidity, and particularly for depressive conditions. A number of specific conditions that can modulate suicidality risk in patients with chronic pain have been investigated, but there is a need for their more specific characterization. Numerous recent studies have shown that demoralization and meaning in life (MiL) constructs affect suicidality as risk and protective factors, respectively. These constructs have been mainly investigated in patients with somatic illness and in community-dwelling individuals who may present with SI or SB independently of a psychiatric diagnosis of depression. However, a paucity of studies investigated them in suicidal patients affected by chronic pain. OBJECTIVE The primary objective of this project is to investigate the relationship between demoralization and MiL on SI risk in patients with chronic pain. The secondary objectives are (1) to test whether demoralization can occur independently of depression in patients with chronic pain and SI, (2) to examine whether the expected association between demoralization and SI may be explained by a sole dimension of demoralization: hopelessness, (3) to examine whether the presence of MiL, but not the search for MiL, is associated with less SI, and (4) to explore whether previously described MiL profiles (ie, high presence-high search, high presence-low search, moderate presence-moderate search, low presence-low search, and low presence-high search) emerge in our cohort. METHODS This project is a single-center, observational, case-control study-the Demoralization and Meaning in Life (DEMiL) study-conducted by the Division of Clinical Pharmacology and Toxicology, the Multidisciplinary Pain Centre, and the Service of Liaison Psychiatry and Crisis Intervention at the Geneva University Hospitals. Self- and hetero-administered questionnaires were conducted among patients and controls, matched by age and gender. The Ethics Committee of the Canton of Geneva approved the scientific utilization of collected data (project No. 2017-02138; decision dated January 25, 2018). Data have been analyzed with SPSS, version 23.0, software (IBM Corp). RESULTS From March 1, 2018, to November 30, 2019, 70 patients and 70 controls were enrolled. Statistical analyses are still in progress and are expected to be finalized in November 2020. To date, we did not observe any unfavorable event for which a causal relationship with the collection of health-related personal data could be ruled out. Results of this study are expected to form the basis for possible prevention and psychotherapeutic interventions oriented toward demoralization and MiL constructs for suicidal patients with chronic pain. CONCLUSIONS The interest in exploring demoralization and MiL in chronic pain patients with SI arises from the common clinical observation that experiencing chronic pain often requires a revision of one's life goals and expectations. Hence, the impact of chronic pain is not limited to patients' biopsychosocial functioning, but it affects the existential domain as well. The major clinical implications in suicidal patients with chronic pain consist in trying to (1) delineate a more precise and individualized suicide risk profile, (2) improve detection and prevention strategies by investigating SI also in individuals who do not present with a clinically diagnosed depression, and (3) enhance the panel of interventions by broadening supportive or psychotherapeutic actions, taking into consideration the existential condition of a person who suffers and strives to deal with his or her suffering.

Preoperative patient activation is predictive of improvements in patient-reported outcomes following minimally invasive lumbar decompression. 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 2020; 29:2222-2230.

Abstract
PURPOSE To determine whether there is an association between preoperative 10-Item Patient Activation Measure (PAM-10) scores and clinical outcomes following MIS LD. METHODS Patients undergoing a primary MIS LD were retrospectively reviewed and stratified according to their preoperative PAM-10 scores: "low PAM," "moderate PAM," and "high PAM." Preoperative PAM score cohorts were tested for improvements in Oswestry Disability Index (ODI), 12-Item Short-Form Physical Component Score (SF-12 PCS), and Visual Analog Scale (VAS) back and leg pain using multivariate linear regression. RESULTS Eighty-nine patients were included: 29 had a low PAM score, 32 had a moderate PAM score, and 28 had a high PAM score. Cohorts experienced similar preoperative VAS back pain, VAS leg pain, ODI, and SF-12 PCS. Patients with low PAM scores experienced a trend of higher pain scores throughout 6 months with VAS back pain being significant at 3 months and VAS leg pain being significant at 6-week and 3-month follow-up. Patients with lower PAM scores experienced a worse improvement in ODI at 6-week, 3-month, and 6-month timepoints. Lastly, patients with lower PAM scores demonstrated less improvement in SF-12 PCS at 3-month and 6-month follow-up. CONCLUSIONS Lower preoperative PAM scores were associated with worse improvement in clinical outcomes following MIS LD. Patients with lower PAM scores had diminished improvement in long-term patient-reported outcomes including ODI, SF-12, and VAS back and leg pain. Our investigation suggests that preoperative PAM assessments may be an effective tool to predict postoperative outcomes following MIS LD.

Abstract
OBJECTIVE Recurrent vaso-occlusive pain episodes, the most common complication of sickle cell disease (SCD), cause frequent health care utilization. Studies exploring associations between patient activation and acute health care utilization for pain are lacking. We tested the hypothesis that increased activation and self-efficacy are associated with decreased health care utilization for pain in SCD. METHODS In this cross-sectional study of adults with SCD at a tertiary medical center, we collected demographics, SCD phenotype, Patient Activation Measure levels, and self-efficacy scores using structured questionnaires. We reviewed charts to obtain disease-modifying therapy and acute health care utilization, defined as emergency room visits and hospitalizations, for vaso-occlusive pain episodes. Negative binomial regression analyses were used to test the hypothesis. RESULTS We surveyed 67 adults with SCD. The median age was 27.0 years, 53.7% were female, and 95.5% were African American. Median health care utilization for pain over one year (range) was 2.0 (0-24). Only one-third of participants (38.8%) were at the highest activation level (median [range] = 3 [1-4]). Two-thirds (65.7%) of participants had high self-efficacy (median [range] = 32.0 [13-45]). Regressions showed significant association between health care utilization and activation (incidence rate ratio [IRR] = 0.663, P = 0.045), self-efficacy (IRR = 0.947, P = 0.038), and male sex (IRR = 0.390, P = 0.003). Two outliers with high activation, self-efficacy, and health care utilization also had addictive behavior. CONCLUSIONS Many individuals with SCD have suboptimal activation and reduced self-efficacy. Higher activation and self-efficacy were associated with lower health care utilization for pain. Additional studies are needed to evaluate interventions to improve activation and self-efficacy and reduce acute health care utilization for pain.

Abstract
STUDY DESIGN A prospective cohort study. OBJECTIVE The current study utilized quantitative gait analysis to examine the relationship of fear-avoidance beliefs to gait patterns in patients with adult degenerative scoliosis (ADS). SUMMARY OF BACKGROUND DATA Among patients with chronic spine pain, fear-avoidance beliefs are predictive of behavioral deficiencies, poor work, and surgery outcomes. The impact of such beliefs on patients with major spinal deformity has yet to be investigated. Patients with ADS have previously been shown to have an altered gait pattern. Utilizing quantified gait analysis, this study aims to examine correlations between fear-avoidance and various aspects of gait in patients with ADS. METHODS Twenty-five ADS patients completed the Tampa Scale for Kinesiophobia (TSK) questionnaire and the Fear Avoidance Beliefs Questionnaire (FABQ). Each patient performed a series of overground gait trials at a self-selected comfortable speed. Pearson product correlation analysis was used to determine the relationship between the self-reported fear of movement measures and the objective gait analysis biomechanical data. RESULTS TSK score correlated strongly with gait speed, stride, step, double support times, and step length, and correlated moderately with cadence, and stride length. The FABQ physical portion strongly correlated with stride length and step length. The FABQ physical portion was moderately correlated with gait speed and single support time. The FABQ work portion was correlated with stride length and step length. CONCLUSION This study demonstrates a strong correlation between biomechanical gait parameters, as measured with gait analysis, and fear-avoidance of movement, as measured with the TSK and FABQ. Further, it demonstrates that quantified gait analysis can be a useful tool to evaluate patients with spine deformity and to assess the outcomes of treatments in this group of patients. This study extends previous research on the role of fear-avoidance to include patients with spinal deformity. LEVEL OF EVIDENCE 3.
