Item Open Access Adherence to Pharmacological Smoking Cessation Interventions: A Literature Review and Synthesis of Correlates and Barriers.(Nicotine & tobacco research : official journal of the Society for Research on Nicotine and Tobacco, 2018-09) Pacek, Lauren R; McClernon, F Joseph; Bosworth, Hayden BIntroduction
Efficacious pharmacological interventions for smoking cessation are available, but poor adherence to these treatments may limit these interventions overall impact. To improve adherence to smoking cessation interventions, it is first necessary to identify and understand smoker-level characteristics that drive nonadherence (ie, nonconformance with a provider's recommendation of timing, dosage, or frequency of medication-taking during the prescribed length of time).Methods
We present a literature review of studies examining correlates of, or self-reported reasons for, nonadherence to smoking cessation pharmacotherapies. Studies were identified through PubMed-using MeSH terms, Embase-using Emtree terms, and ISI Web of Science.Results and conclusions
This literature review included 50 studies that examined nonpreventable (eg, sociodemographics) and preventable (eg, forgetfulness) factors associated with adherence to smoking cessation medication and suggestions for overcoming some of the identified barriers. Systematic study of this topic would be facilitated by consistent reporting of adherence and correlates thereof in the literature, development of consistent definitions of medication adherence across studies, utilization of more objective measures of adherence (eg, blood plasma levels vs. self-report) in addition to reliance on self-reported adherence.Implications
This article provides the most comprehensive review to date on correlates of adherence to pharmacological smoking cessation interventions. Challenges and specific gaps in the literature that should be a priority for future research are discussed. Future priorities include additional research, particularly among vulnerable populations of smokers, developing standardized definitions of adherence and methods for measuring adherence, regular assessment of cessation pharmacotherapy adherence in the context of research and clinical practice, and development of novel treatments aimed at preventable barriers to medication adherence.Item Open Access Allopregnanolone Levels Are Inversely Associated with Self-Reported Pain Symptoms in U.S. Iraq and Afghanistan-Era Veterans: Implications for Biomarkers and Therapeutics.(Pain Med, 2016-01) Naylor, Jennifer C; Kilts, Jason D; Szabo, Steven T; Dunn, Charlotte E; Keefe, Francis J; Tupler, Larry A; Shampine, Lawrence J; Morey, Rajendra A; Strauss, Jennifer L; Hamer, Robert M; Wagner, H Ryan; MIRECC Workgroup; Marx, Christine EBACKGROUND AND OBJECTIVES: Pain symptoms are common among Iraq/Afghanistan-era veterans, many of whom continue to experience persistent pain symptoms despite multiple pharmacological interventions. Preclinical data suggest that neurosteroids such as allopregnanolone demonstrate pronounced analgesic properties, and thus represent logical biomarker candidates and therapeutic targets for pain. Allopregnanolone is also a positive GABAA receptor modulator with anxiolytic, anticonvulsant, and neuroprotective actions in rodent models. We previously reported inverse associations between serum allopregnanolone levels and self-reported pain symptom severity in a pilot study of 82 male veterans. METHODS: The current study investigates allopregnanolone levels in a larger cohort of 485 male Iraq/Afghanistan-era veterans to attempt to replicate these initial findings. Pain symptoms were assessed by items from the Symptom Checklist-90-R (SCL-90-R) querying headache, chest pain, muscle soreness, and low back pain over the past 7 days. Allopregnanolone levels were quantified by gas chromatography/mass spectrometry. RESULTS: Associations between pain ratings and allopregnanolone levels were examined with Poisson regression analyses, controlling for age and smoking. Bivariate nonparametric Mann–Whitney analyses examining allopregnanolone levels across high and low levels of pain were also conducted. Allopregnanolone levels were inversely associated with muscle soreness [P = 0.0028], chest pain [P = 0.032], and aggregate total pain (sum of all four pain items) [P = 0.0001]. In the bivariate analyses, allopregnanolone levels were lower in the group reporting high levels of muscle soreness [P = 0.001]. CONCLUSIONS: These findings are generally consistent with our prior pilot study and suggest that allopregnanolone may function as an endogenous analgesic. Thus, exogenous supplementation with allopregnanolone could have therapeutic potential. The characterization of neurosteroid profiles may also have biomarker utility.Item Open Access An Initial Evaluation of the Impact of Pokémon GO on Physical Activity.(Journal of the American Heart Association, 2017-05-16) Xian, Ying; Xu, Hanzhang; Xu, Haolin; Liang, Li; Hernandez, Adrian F; Wang, Tracy Y; Peterson, Eric DPokémon GO is a location-based augmented reality game. Using GPS and the camera on a smartphone, the game requires players to travel in real world to capture animated creatures, called Pokémon. We examined the impact of Pokémon GO on physical activity (PA).A pre-post observational study of 167 Pokémon GO players who were self-enrolled through recruitment flyers or online social media was performed. Participants were instructed to provide screenshots of their step counts recorded by the iPhone Health app between June 15 and July 31, 2016, which was 3 weeks before and 3 weeks after the Pokémon GO release date. Of 167 participants, the median age was 25 years (interquartile range, 21-29 years). The daily average steps of participants at baseline was 5678 (SD, 2833; median, 5718 [interquartile range, 3675-7279]). After initiation of Pokémon GO, daily activity rose to 7654 steps (SD, 3616; median, 7232 [interquartile range, 5041-9744], pre-post change: 1976; 95% CI, 1494-2458, or a 34.8% relative increase [P<0.001]). On average, 10 000 "XP" points (a measure of game progression) was associated with 2134 additional steps per day (95% CI, 1673-2595), suggesting a potential dose-response relationship. The number of participants achieving a goal of 10 000+ steps per day increased from 15.3% before to 27.5% after (odds ratio, 2.06; 95% CI, 1.70-2.50). Increased PA was also observed in subgroups, with the largest increases seen in participants who spent more time playing Pokémon GO, those who were overweight/obese, or those with a lower baseline PA level.Pokémon GO participation was associated with a significant increase in PA among young adults. Incorporating PA into gameplay may provide an alternative way to promote PA in persons who are attracted to the game.URL: http://www.clinicaltrials.gov.

The purpose of this study was to evaluate the association between self-reported hearing handicap and life-space mobility utilizing the Life-Space Questionnaire (LSQ). Life-space mobility reflects how an individual moves through their daily physical and social environment, and the role of hearing loss in life-space mobility is not fully understood. We hypothesized that those with higher self-reported hearing handicap would be more likely to demonstrate restricted life-space mobility.Method
A total of 189 older adults (M age = 75.76 years, SD = 5.81) completed a mail-in survey packet including the LSQ and Hearing Handicap Inventory for the Elderly (HHIE). Participants were categorized into one of three groups ("no/none," "mild/moderate," or "severe" hearing handicap) according to HHIE total score. LSQ responses were dichotomized to either "nonrestricted/typical" or "restricted" life-space mobility groups. Logistic regression models were performed to analyze life-space mobility differences among the groups.Results
Logistic regression results demonstrated no statistically significant association between hearing handicap and LSQ.Conclusions
The results of this study indicate that there is no association between self-reported hearing handicap and life-space mobility as evaluated using a mail-in version of the LSQ. This counters other studies that have demonstrated that life space is associated with chronic illness, cognitive functioning, and social and health integration.Item Open Access Can caregivers report their care recipients' post-stroke hospitalizations and outpatient visits accurately? Findings of an Asian prospective stroke cohort.(BMC health services research, 2018-10-25) Tyagi, Shilpa; Koh, Gerald Choon-Huat; Luo, Nan; Tan, Kelvin Bryan; Hoenig, Helen; Matchar, David B; Yoong, Joanne; Finkelstein, Eric A; Lee, Kim En; Venketasubramanian, N; Menon, Edward; Chan, Kin Ming; De Silva, Deidre Anne; Yap, Philip; Tan, Boon Yeow; Chew, Effie; Young, Sherry H; Ng, Yee Sien; Tu, Tian Ming; Ang, Yan Hoon; Kong, Keng He; Singh, Rajinder; Merchant, Reshma A; Chang, Hui Meng; Yeo, Tseng Tsai; Ning, Chou; Cheong, Angela; Ng, Yu Li; Tan, Chuen SengBackground
Health services research aimed at understanding service use and improving resource allocation often relies on collecting subjectively reported or proxy-reported healthcare service utilization (HSU) data. It is important to know the discrepancies in such self or proxy reports, as they have significant financial and policy implications. In high-dependency populations, such as stroke survivors, with varying levels of cognitive impairment and dysphasia, caregivers are often potential sources of stroke survivors' HSU information. Most of the work conducted on agreement analysis to date has focused on validating different sources of self-reported data, with few studies exploring the validity of caregiver-reported data. Addressing this gap, our study aimed to quantify the agreement across the caregiver-reported and national claims-based HSU of stroke patients.Methods
A prospective study comprising multi-ethnic stroke patient and caregiver dyads (N = 485) in Singapore was the basis of the current analysis, which used linked national claims records. Caregiver-reported health services data were collected via face-to-face and telephone interviews, and similar health services data were extracted from the national claims records. The main outcome variable was the modified intraclass correlation coefficient (ICC), which provided the level of agreement across both data sources. We further identified the amount of over- or under-reporting by caregivers across different service types.Results
We observed variations in agreement for different health services, with agreement across caregiver reports and national claims records being the highest for outpatient visits (specialist and primary care), followed by hospitalizations and emergency department visits. Interestingly, caregivers over-reported hospitalizations by approximately 49% and under-reported specialist and primary care visits by approximately 20 to 30%.Conclusions
The accuracy of the caregiver-reported HSU of stroke patients varies across different service types. Relatively more objective data sources, such as national claims records, should be considered as a first choice for quantifying health care usage before considering caregiver-reported usage. Caregiver-reported outpatient service use was relatively more accurate than inpatient service use over shorter recall periods. Therefore, in situations where objective data sources are limited, caregiver-reported outpatient information can be considered for low volumes of healthcare consumption, using an appropriate correction to account for potential under-reporting.Item Open Access Childhood maltreatment and impact on clinical features of major depression in adults.(Psychiatry research, 2020-11) Medeiros, Gustavo C; Prueitt, William L; Minhajuddin, Abu; Patel, Shirali S; Czysz, Andrew H; Furman, Jennifer L; Mason, Brittany L; Rush, A John; Jha, Manish K; Trivedi, Madhukar HObjectives
This study examined: 1) the prevalence of childhood maltreatment (CMT) in individuals with chronic and/or recurrent depression, 2) the association between CMT and depressive symptoms, 3) the link between CMT and worse clinical presentation of depression, 4) the effects of accumulation of different types of CMT, and 5) the relationship between the age at CMT and depression.Methods
We analyzed the baseline data of 663 individuals from the CO-MED study. CMT was determined by a brief self-reported questionnaire assessing sexual abuse, emotional abuse, physical abuse, and neglect. Correlational analyses were conducted.Results
Half of the sample (n = 331) reported CMT. Those with CMT had higher rates of panic/phobic, cognitive and anhedonic symptoms than those without CMT. All individual types of maltreatment were associated with a poorer clinical presentation including: 1) earlier MDD onset; 2) more severe MDD, 3) more suiccidality, 4) worse quality of life, and functioning, and 5) more psychiatric comorbidities. Clinical presentation was worse in participants who reported multiple types of CMT.Conclusions
In chronic and/or recurrent depression, CMT is common, usually of multiple types and is associated with a worse clinical presentation in MDD. The combination of multiple types of CMT is associated with more impairment.Item Open Access Detection of depression in low resource settings: validation of the Patient Health Questionnaire (PHQ-9) and cultural concepts of distress in Nepal.(BMC Psychiatry, 2016-03-08) Kohrt, Brandon A; Luitel, Nagendra P; Acharya, Prakash; Jordans, Mark JDBACKGROUND: Despite recognition of the burden of disease due to mood disorders in low- and middle-income countries, there is a lack of consensus on best practices for detecting depression. Self-report screening tools, such as the Patient Health Questionnaire (PHQ-9), require modification for low literacy populations and to assure cultural and clinical validity. An alternative approach is to employ idioms of distress that are locally salient, but these are not synonymous with psychiatric categories. Therefore, our objectives were to evaluate the validity of the PHQ-9, assess the added value of using idioms of distress, and develop an algorithm for depression detection in primary care. METHODS: We conducted a transcultural translation of the PHQ-9 in Nepal using qualitative methods to achieve semantic, content, technical, and criterion equivalence. Researchers administered the Nepali PHQ-9 to randomly selected patients in a rural primary health care center. Trained psychosocial counselors administered a validated Nepali depression module of the Composite International Diagnostic Interview (CIDI) to validate the Nepali PHQ-9. Patients were also assessed for local idioms of distress including heart-mind problems (Nepali, manko samasya). RESULTS: Among 125 primary care patients, 17 (14 %) were positive for a major depressive episode in the prior 2 weeks based on CIDI administration. With a Nepali PHQ-9 cutoff ≥ 10: sensitivity = 0.94, specificity = 0.80, positive predictive value (PPV) =0.42, negative predictive value (NPV) =0.99, positive likelihood ratio = 4.62, and negative likelihood ratio = 0.07. For heart-mind problems: sensitivity = 0.94, specificity = 0.27, PPV = 0.17, NPV = 0.97. With an algorithm comprising two screening questions (1. presence of heart-mind problems and 2. function impairment due to heart-mind problems) to determine who should receive the full PHQ-9, the number of patients requiring administration of the PHQ-9 could be reduced by 50 %, PHQ-9 false positives would be reduced by 18 %, and 88 % of patients with depression would be correctly identified. CONCLUSION: Combining idioms of distress with a transculturally-translated depression screener increases efficiency and maintains accuracy for high levels of detection. The algorithm reduces the time needed for primary healthcare staff to verbally administer the tool for patients with limited literacy. The burden of false positives is comparable to rates in high-income countries and is a limitation for universal primary care screening.Item Open Access How Reliable are Patient-Reported Rehospitalizations? Implications for the Design of Future Practical Clinical Studies.(J Am Heart Assoc, 2016-01-25) Krishnamoorthy, Arun; Peterson, Eric D; Knight, J David; Anstrom, Kevin J; Effron, Mark B; Zettler, Marjorie E; Davidson-Ray, Linda; Baker, Brian A; McCollam, Patrick L; Mark, Daniel B; Wang, Tracy YBACKGROUND: Longitudinal clinical investigations often rely on patient reports to screen for postdischarge adverse outcomes events, yet few studies have examined the accuracy of such patient reports. METHODS AND RESULTS: Patients with acute myocardial infarction (MI) in the TRANSLATE-ACS study were asked during structured interviews at 6 weeks, 6 months, and 12 months postdischarge to report any rehospitalizations. The accuracy of patient-reported rehospitalizations within 1 year of postdischarge was determined using claims-based medical bill validation as the reference standard. The cumulative incidence of rehospitalizations was compared when identified by patient report versus medical bills. Patients were categorized by the accuracy in reporting events (accurate, under-, or over- reporters) and characteristics were compared between groups. Among 10 643 MI patients, 4565 (43%) reported 7734 rehospitalizations. The sensitivity and positive predictive value of patient-reported rehospitalizations were low at 67% and 59%, respectively. A higher cumulative incidence of rehospitalization was observed when identified by patient report versus medical bills (43% vs 37%; P<0.001). Overall, 18% of patients over-reported and 10% under-reported the number of hospitalizations. Compared with accurate reporters, under-reporters were more likely to be older, female, African American, unemployed, or a non-high-school graduate, and had greater prevalence of clinical comorbidities such as diabetes and past cardiovascular disease. CONCLUSIONS: The accuracy of patient-reported rehospitalizations was low with patients both under- and over-reporting events. Longitudinal clinical research studies need additional mechanisms beyond patient report to accurately identify rehospitalization events. CLINICAL TRIAL REGISTRATION: URL: https://clinicaltrials.gov.

Falls are considered a significant public health issue and falls risk increases with age. There are many age-related physiologic changes that occur that increase postural instability and the risk for falls (i.e., age-related sensory declines in vision, vestibular, somatosensation, age-related orthopedic changes, and polypharmacy). Hearing loss has been shown to be an independent risk factor for falls. The primary objective of this study was to determine if hearing aid use modified (reduced) the association between self-reported hearing status and falls or falls-related injury. We hypothesized that hearing aid use would reduce the impact of hearing loss on the odds of falling and falls-related injury. If hearing aid users have reduced odds of falling compared with nonhearing aid users, then that would have an important implications for falls prevention healthcare.Design
Data were drawn from the 2004-2016 surveys of the Health and Retirement Study (HRS). A generalized estimating equation approach was used to fit logistic regression models to determine whether or not hearing aid use modifies the odds of falling and falls injury associated with self-reported hearing status.Results
A total of 17,923 individuals were grouped based on a self-reported history of falls. Self-reported hearing status was significantly associated with odds of falling and with falls-related injury when controlling for demographic factors and important health characteristics. Hearing aid use was included as an interaction in the fully-adjusted models and the results showed that there was no difference in the association between hearing aid users and nonusers for either falls or falls-related injury.Conclusions
The results of the present study show that when examining self-reported hearing status in a longitudinal sample, hearing aid use does not impact the association between self-reported hearing status and the odds of falls or falls-related injury.Item Open Access Impact of preoperative depression on 2-year clinical outcomes following adult spinal deformity surgery: the importance of risk stratification based on type of psychological distress.(Journal of neurosurgery. Spine, 2016-10) Theologis, Alexander A; Ailon, Tamir; Scheer, Justin K; Smith, Justin S; Shaffrey, Christopher I; Bess, Shay; Gupta, Munish; Klineberg, Eric O; Kebaish, Khaled; Schwab, Frank; Lafage, Virginie; Burton, Douglas; Hart, Robert; Ames, Christopher P; International Spine Study GroupOBJECTIVE The objective of this study was to isolate whether the effect of a baseline clinical history of depression on outcome is independent of associated physical disability and to evaluate which mental health screening tool has the most utility in determining 2-year clinical outcomes after adult spinal deformity (ASD) surgery. METHODS Consecutively enrolled patients with ASD in a prospective, multicenter ASD database who underwent surgical intervention with a minimum 2-year follow-up were retrospectively reviewed. A subset of patients who completed the Distress and Risk Assessment Method (DRAM) was also analyzed. The effects of categorical baseline depression and DRAM classification on the Oswestry Disability Index (ODI), SF-36, and Scoliosis Research Society questionnaire (SRS-22r) were assessed using univariate and multivariate linear regression analyses. The probability of achieving ≥ 1 minimal clinically important difference (MCID) on the ODI based on the DRAM's Modified Somatic Perceptions Questionnaire (MSPQ) score was estimated. RESULTS Of 267 patients, 66 (24.7%) had self-reported preoperative depression. Patients with baseline depression had significantly more preoperative back pain, greater BMI and Charlson Comorbidity Indices, higher ODIs, and lower SRS-22r and SF-36 Physical/Mental Component Summary (PCS/MCS) scores compared with those without self-reported baseline depression. They also had more severe regional and global sagittal malalignment. After adjusting for these differences, preoperative depression did not impact 2-year ODI, PCS/MCS, or SRS-22r totals (p > 0.05). Compared with those in the "normal" DRAM category, "distressed somatics" (n = 11) had higher ODI (+23.5 points), lower PCS (-10.9), SRS-22r activity (-0.9), and SRS-22r total (-0.8) scores (p ≤ 0.01), while "distressed depressives" (n = 25) had lower PCS (-8.4) and SRS-22r total (-0.5) scores (p < 0.05). After adjusting for important covariates, each additional point on the baseline MSPQ was associated with a 0.8-point increase in 2-year ODI (p = 0.03). The probability of improving by at least 1 MCID in 2-year ODI ranged from 77% to 21% for MSPQ scores 0-20, respectively. CONCLUSIONS A baseline clinical history of depression does not correlate with worse 2-year outcomes after ASD surgery after adjusting for baseline differences in comorbidities, health-related quality of life, and spinal deformity severity. Conversely, DRAM improved risk stratification of patient subgroups predisposed to achieving suboptimal surgical outcomes. The DRAM's MSPQ was more predictive than MCS and SRS mental domain for 2-year outcomes and may be a valuable tool for surgical screening.Item Open Access Implementation of a group physical therapy program for Veterans with knee osteoarthritis.(BMC musculoskeletal disorders, 2020-02) Allen, Kelli D; Sheets, Brandon; Bongiorni, Dennis; Choate, Ashley; Coffman, Cynthia J; Hoenig, Helen; Huffman, Kim; Mahanna, Elizabeth P; Oddone, Eugene Z; Van Houtven, Courtney; Wang, Virginia; Woolson, Sandra; Hastings, Susan NBACKGROUND:A previous randomized clinical trial found that a Group Physical Therapy (PT) program for knee osteoarthritis yielded similar improvements in pain and function compared with traditional individual PT. Based on these findings the Group PT program was implemented in a Department of Veterans Affairs Health Care System. The objective of this study was to evaluate implementation metrics and changes in patient-level measures following implementation of the Group PT program. METHODS:This was a one-year prospective observational study. The Group PT program involved 6 weekly sessions. Implementation metrics included numbers of referrals and completed sessions. Patient-level measures were collected at the first and last PT sessions and included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC; self-report of pain, stiffness and function (range 0-96)) and a 30-s chair rise test. RESULTS:During the evaluation period, 152 patients were referred, 80 had an initial session scheduled, 71 completed at least one session and 49 completed at least 5 sessions. The mean number of completed appointments per patient was 4.1. Among patients completing baseline and follow-up measures, WOMAC scores (n = 33) improved from 56.8 (SD = 15.8) to 46.9 (SD = 14.0); number of chair rises (n = 38) completed in 30 s increased from 10.4 (SD = 5.1) to 11.9 (SD = 5.0). CONCLUSIONS:Patients completing the Group PT program in this implementation phase showed clinically relevant improvements comparable to those observed in the previous clinical trial that compared group and individual PT for knee osteoarthritis. These results are important because Group PT can improve efficiency and access compared with individual PT. However, there were some limitations with respect to attendance and completion rates, and program adaptations may be needed to optimize these implementation metrics. Larger, longer-term studies are required to more fully evaluate the effectiveness of this program.Item Open Access Measuring social health in the patient-reported outcomes measurement information system (PROMIS): item bank development and testing.(Quality of life research : an international journal of quality of life aspects of treatment, care and rehabilitation, 2010-09) Hahn, Elizabeth A; Devellis, Robert F; Bode, Rita K; Garcia, Sofia F; Castel, Liana D; Eisen, Susan V; Bosworth, Hayden B; Heinemann, Allen W; Rothrock, Nan; Cella, David; PROMIS Cooperative GroupPurpose
To develop a social health measurement framework, to test items in diverse populations and to develop item response theory (IRT) item banks.Methods
A literature review guided framework development of Social Function and Social Relationships sub-domains. Items were revised based on patient feedback, and Social Function items were field-tested. Analyses included exploratory factor analysis (EFA), confirmatory factor analysis (CFA), two-parameter IRT modeling and evaluation of differential item functioning (DIF).Results
The analytic sample included 956 general population respondents who answered 56 Ability to Participate and 56 Satisfaction with Participation items. EFA and CFA identified three Ability to Participate sub-domains. However, because of positive and negative wording, and content redundancy, many items did not fit the IRT model, so item banks do not yet exist. EFA, CFA and IRT identified two preliminary Satisfaction item banks. One item exhibited trivial age DIF.Conclusion
After extensive item preparation and review, EFA-, CFA- and IRT-guided item banks help provide increased measurement precision and flexibility. Two Satisfaction short forms are available for use in research and clinical practice. This initial validation study resulted in revised item pools that are currently undergoing testing in new clinical samples and populations.Item Open Access Meclizine enhancement of sensorimotor gating in healthy male subjects with high startle responses and low prepulse inhibition.(Neuropsychopharmacology : official publication of the American College of Neuropsychopharmacology, 2014-02) Larrauri, José A; Kelley, Lisalynn D; Jenkins, Mason R; Westman, Eric C; Schmajuk, Nestor A; Rosenthal, M Zachary; Levin, Edward DHistamine H1 receptor systems have been shown in animal studies to have important roles in the reversal of sensorimotor gating deficits, as measured by prepulse inhibition (PPI). H1-antagonist treatment attenuates the PPI impairments caused by either blockade of NMDA glutamate receptors or facilitation of dopamine transmission. The current experiment brought the investigation of H1 effects on sensorimotor gating to human studies. The effects of the histamine H1 antagonist meclizine on the startle response and PPI were investigated in healthy male subjects with high baseline startle responses and low PPI levels. Meclizine was administered to participants (n=24) using a within-subjects design with each participant receiving 0, 12.5, and 25 mg of meclizine in a counterbalanced order. Startle response, PPI, heart rate response, galvanic skin response, and changes in self-report ratings of alertness levels and affective states (arousal and valence) were assessed. When compared with the control (placebo) condition, the two doses of meclizine analyzed (12.5 and 25 mg) produced significant increases in PPI without affecting the magnitude of the startle response or other physiological variables. Meclizine also caused a significant increase in overall self-reported arousal levels, which was not correlated with the observed increase in PPI. These results are in agreement with previous reports in the animal literature and suggest that H1 antagonists may have beneficial effects in the treatment of subjects with compromised sensorimotor gating and enhanced motor responses to sensory stimuli.Item Open Access Medication non-adherence after myocardial infarction: an exploration of modifying factors.(Journal of general internal medicine, 2015-01) Crowley, Matthew J; Zullig, Leah L; Shah, Bimal R; Shaw, Ryan J; Lindquist, Jennifer H; Peterson, Eric D; Bosworth, Hayden BBackground
Medication non-adherence is a major impediment to the management of cardiovascular disease risk factors. A better understanding of the modifying factors underlying medication non-adherence among individuals with known cardiovascular disease may inform approaches for addressing non-adherence.Objective
The purpose of this study was to identify demographic and patient characteristics, medical comorbidities, psychosocial factors, and health belief-related factors associated with medication non-adherence among patients with known cardiovascular disease.Design
We performed secondary analysis of baseline data from a randomized trial.Patients
The study included 405 patients with a diagnosis of hypertension and history of acute myocardial infarction that was diagnosed within a three-year period prior to enrollment.Main measures
Baseline demographics and patient characteristics, medical comorbidities, psychosocial factors, health belief-related factors, and patient-reported medication non-adherence were analyzed.Key results
Of 405 patients, 173 (42.7 %) reported medication non-adherence. Factors associated with non-adherence in bivariate analysis included younger age, non-white race, having less than 12 years of education, smoking, financial insecurity, identifying as nervous or tense, higher life chaos score, greater worry about having a myocardial infarction, and greater worry about having a stroke. Using multivariable modeling, we determined that age (OR 0.97 per additional year, 95 % CI, 0.95-0.99), life chaos (OR 1.06 per additional point, 95 % CI, 1.00-1.11), and worry about stroke (OR 1.12 per additional point, 95 % CI, 1.01-1.25) remained significantly associated with self-reported medication non-adherence.Conclusions
We found that worry about having a stroke, higher life chaos, and younger age were all significantly associated with self-reported medication non-adherence in patients with cardiovascular disease and a history of myocardial infarction. Further research exploring these factors as targets for intervention is needed, as is additional research examining modifiable causes of medication non-adherence among patients with cardiovascular disease.Item Open Access On the Concurrent Use of Self-System Therapy and Functional Magnetic Resonance Imaging-Guided Transcranial Magnetic Stimulation as Treatment for Depression.(The journal of ECT, 2018-12) Neacsiu, Andrada D; Luber, Bruce M; Davis, Simon W; Bernhardt, Elisabeth; Strauman, Timothy J; Lisanby, Sarah HObjectives
Despite the growing use of repetitive transcranial magnetic stimulation (rTMS) as a treatment for unipolar depression, its typical effect sizes have been modest, and methodological and conceptual challenges remain regarding how to optimize its efficacy. Linking rTMS to a model of the neurocircuitry underlying depression and applying such a model to personalize the site of stimulation may improve the efficacy of rTMS. Recent developments in the psychology and neurobiology of self-regulation offer a conceptual framework for identifying mechanisms of action in rTMS for depression, as well as for developing guidelines for individualized rTMS treatment. We applied this framework to develop a multimodal treatment for depression by pairing self-system therapy (SST) with simultaneously administered rTMS delivered to an individually targeted region of dorsolateral prefrontal cortex identified via functional magnetic resonance imaging (fMRI).Methods
In this proof-of-concept study, we examined the acceptability, feasibility, and preliminary efficacy of combining individually fMRI-targeted rTMS with SST. Using the format of a cognitive paired associative stimulation paradigm, the treatment was administered to 5 adults with unipolar depression in an open-label trial.Results
The rTMS/SST combination was well tolerated, feasible, and acceptable. Preliminary evidence of efficacy also was promising. We hypothesized that both treatment modalities were targeting the same neural circuitry through cognitive paired associative stimulation, and observed changes in task-based fMRI were consistent with our model. These neural changes were directly related to improvements in depression severity.Conclusions
The new combination treatment represents a promising exemplar for theory-based, individually targeted, multimodal intervention in mood disorders.Item Open Access Patient Factors That Influence Decision Making: Randomization Versus Observational Nonoperative Versus Observational Operative Treatment for Adult Symptomatic Lumbar Scoliosis.(Spine, 2016-03) Neuman, Brian J; Baldus, Christine; Zebala, Lukas P; Kelly, Michael P; Shaffrey, Christopher; Edwards, Charles; Koski, Tyler; Schwab, Frank; Glassman, Steven; Parent, Stefan; Lewis, Stephen; Lenke, Lawrence G; Buchowski, Jacob M; Smith, Justin S; Crawford, Charles H; Kim, Han Jo; Lafage, Virginia; Lurie, Jon; Carreon, Leah; Bridwell, Keith HStudy design
A prospective study with randomized and observational cohorts.Objective
The aim of this study was to determine baseline variables affecting adult symptomatic lumbar scoliosis (ASLS) decision making to participate in randomization (RAND), observational nonsurgical (OBS-NS), or observational surgical (OBS-S) cohorts.Summary of background data
Multiple factors play a key role in a patient's decision to be randomized or to choose an OBS-NS or OBS-S course for ASLS. Studies evaluating these factors are limited.Methods
Eligible candidates (patients with ASLS and no prior spinal fusion deformity surgery) from 9 centers participated in a RAND, OBS-NS, or OBS-S cohort study. Baseline variables (demographics, socioeconomics, patient-reported outcomes [PROs], Functional Treadmill Test, radiographs) were analyzed.Results
Two hundred ninety-five patients were enrolled: 67 RAND, 115 OBS-NS, 113 OBS-S. Subanalysis of older patients (60-80 years) found 54% of OBS-NS had college degrees compared with 82% of RAND and 71% of OBS-S (P = 0.010). Patients deciding to be part of a RAND cohort have similar clinical characteristics to the OBS-S cohort. OBS-S had more symptomatic spinal stenosis (57% vs. 39%, P = 0.029) and worse scores than OBS-NS on the basis of PROs (Back Pain Numerical Rating Scale [NRS 6.3 vs. 5.5, P = 0.007]; Scoliosis Research Society [SRS] Pain [2.8 vs. 3.0, P = 0.018], Function [3.1 vs. 3.4, P = 0.019] and Self-Image [2.7 vs. 3.1, P = 0.002]; Oswestry Disability Index (ODI) [36.9 vs. 31.8, P = 0.029]; post-Treadmill back [5.8 vs. 4.4, P = 0.002] and leg [4.3 vs. 3.1, P = 0.037] pain NRS and larger lumbar coronal Cobb angles (56.5 degrees vs. 48.8 degrees, P < 0.001). RAND had more baseline motor deficits (10.4% vs. 1.7%, P = 0.036) and worse scores than OBS-NS on the basis of ODI (38.8 vs. 31.8, P = 0.006), SRS Function [3.1 vs. 3.4, P = 0.034], and Self-Image [2.7 vs. 3.1, P = 0.007].Conclusion
Patients with worse PROs, more back pain, more back and leg pain with ambulation, and larger lumbar Cobb angles are more inclined to select surgical over nonsurgical management.Item Open Access Patient Satisfaction After Adult Spinal Deformity Surgery Does Not Strongly Correlate With Health-Related Quality of Life Scores, Radiographic Parameters, or Occurrence of Complications.(Spine, 2017-05) Hamilton, David Kojo; Kong, Christopher; Hiratzka, Jayme; Contag, Alec G; Ailon, Tamir; Line, Breton; Daniels, Alan; Smith, Justin S; Passias, Peter; Protopsaltis, Themistocles; Sciubba, Daniel; Burton, Douglas; Shaffrey, Christopher; Klineberg, Eric; Mundis, Gregory; Kim, Han-Jo; Lafage, Virginie; Lafage, Renaud; Scheer, Justin; Boachie-Adjei, Oheneba; Bess, Shay; Hart, Robert AStudy design
This is a multicenter retrospective review of prospectively collected cases.Objective
Our objective was to evaluate the relationship between patient satisfaction, health-related quality of life (HRQoL) scores, complications, and radiographic measures at 2 years postoperative follow-up.Summary of background data
For patients receiving operative management for adult spine deformity (ASD), the relationship between HRQoL measures, radiographic parameters, postoperative complications, and self-reported satisfaction remains unclear.Methods
Data from 248 patients across 11 centers within the United States who underwent thoracolumbar fusion for ASD and had a minimum of 2 years follow-up was collected. Pre- and postoperative scores were obtained from the Scoliosis Research Society 22-item (SRS-22r), the Oswestry Disability Index (ODI), the 36-Item Short Form Health Survey (SF-36), and the Visual Analogue Scale. Sagittal vertical axis, coronal C7 plumbline, lumbar lordosis, pelvic tilt, T1 pelvic angle, and the difference between pelvic incidence and lumbar lordosis were assessed using postoperative radiographic films. Satisfaction (SAT) was assessed using the SRS-22r; patients were categorized as highly satisfied (HS) or less satisfied (LS). The correlation between SAT and HRQoL scores, radiographic parameters, and complications was determined.Results
When compared with LS (n = 60) patients, HS (n = 188) patients demonstrated greater improvement in final ODI, SF-36 component scores, SRS-Total, and Visual Analogue Scale back scores (P < 0.05). The correlations between SAT and the final follow-up and 2 year change from baseline values were moderate for Mental Component Summary, Physical Component Summary, and ODI or weak for HRQoL scores (P < 0.0001). The HS and LS groups were equal in pre- or final postoperative radiographic parameters. Occurrence of complications had no effect on satisfaction.Conclusion
Among operatively treated ASD patients, satisfaction was moderately correlated with some HRQoL measures, and not with radiographic changes or postoperative complications. Other factors, such as patient expectations and relationship with the surgeon, may be stronger drivers of patient satisfaction.Level of evidence
3.Item Open Access Perceived cannabis use norms and cannabis use among adolescents in the United States.(J Psychiatr Res, 2015-05) Wu, Li-Tzy; Swartz, Marvin S; Brady, Kathleen T; Hoyle, Rick H; NIDA AAPI WorkgroupDue to changes in cannabis policies, concerns about cannabis use (CU) in adolescents have increased. The population of nonwhite groups is growing quickly in the United States. We examined perceived CU norms and their association with CU and CU disorder (CUD) for White, Black, Hispanic, Native-American, Asian-American, Native Hawaiian/Pacific Islander (NH/PI), and mixed-race adolescents. Data were from adolescents (12-17 years) in the 2004-2012 National Surveys on Drug Use and Health (N = 163,837). Substance use and CUD were assessed by computer-assisted, self-interviewing methods. Blacks, Hispanics, Native-Americans, and mixed-race adolescents had greater odds of past-year CU and CUD than Whites. Among past-year cannabis users (CUs), Hispanics and Native-Americans had greater odds of having a CUD than Whites. Asian-Americans had the highest prevalence of perceived parental or close friends' CU disapproval. Native-Americans and mixed-race adolescents had lower odds than Whites of perceiving CU disapproval from parents or close friends. In adjusted analyses, adolescent's disapproval of CU, as well as perceived disapproval by parents or close friends, were associated with a decreased odds of CU in each racial/ethnic group, except for NHs/PIs. Adolescent's disapproval of CU was associated with a decreased odds of CUD among CUs for Whites (personal, parental, and close friends' disapproval), Hispanics (personal, parental, and close friends' disapproval), and mixed-race adolescents (personal, close friends' disapproval). Racial/ethnic differences in adolescent CU prevalence were somewhat consistent with adolescents' reports of CU norm patterns. Longitudinal research on CU health effects should oversample nonwhite adolescents to assure an adequate sample for analysis and reporting.Item Open Access Postoperative cervical deformity in 215 thoracolumbar patients with adult spinal deformity: prevalence, risk factors, and impact on patient-reported outcome and satisfaction at 2-year follow-up.(Spine, 2015-03) Passias, Peter G; Soroceanu, Alex; Smith, Justin; Boniello, Anthony; Yang, Sun; Scheer, Justin K; Schwab, Frank; Shaffrey, Christopher; Kim, Han Jo; Protopsaltis, Themistocles; Mundis, Gregory; Gupta, Munish; Klineberg, Eric; Lafage, Virginie; Ames, Christopher; International Spine Study GroupStudy design
Retrospective review of prospective multicenter database.Objective
Quantify the incidence of new onset cervical deformity (CD) after adult spinal deformity surgery of the thoracolumbar spine, identify predictors of development, and determine the impact on outcomes.Summary of background data
High prevalence of residual CD has been identified after surgical treatment of adult spinal deformity. Development of new onset CD is less understood and its clinical impact unclear.Methods
A total of 215 patients with complete 2-year follow-up and full-length radiographs met inclusion criteria. CD was defined by T1 slope minus Cervical Lordosis (CL) more than 20°, C2-C7 sagittal vertical axis more than 40 mm, or C2-C7 kyphosis more than 10°. Univariate analysis was performed using t tests or tests of proportion. Multivariate logistic regression was used to determine independent predictors of new onset CD. The impact of CD on health-related quality of life and satisfaction was measured using repeated measures mixed models or logistic regression as appropriate, accounting for potential confounders.Results
The overall rate of CD at 2 years after surgery was 63%. Univariate analysis revealed that patients who developed new onset CD postoperatively had higher incidence of diabetes (7.35% vs. 1.28%, P = 0.05), increased preoperative C2-C7 sagittal vertical axis (P = 0.04) and C2 slope (P = 0.038), and smaller diameter rods used at surgery (P = 0.032). Independent predictors of new onset CD at 2 years included: diabetes (odds ratio, 10.49; P = 0.046) and increased preoperative T1 slope minus cervical lordosis (odds ratio, 1.08/º; P = 0.022). Ending instrumentation below T4 was a negative predictor (odds ratio, 0.31; P = 0.019). Patients with and without CD experienced improvements in 2-year 36-Item Short Form Health Survey (P = 0.0001), Oswestry Disability Index (P = 0.0001), and Scoliosis Research Society (P = 0.0001). Rates and overall improvement were similar. CD was not associated with decreased satisfaction (P = 0.28).Conclusion
A total of 47.7% of patients without preoperative CD developed new onset postoperative CD after thoracolumbar surgery. Independent predictors of new onset CD at 2 years included diabetes, higher preoperative T1 slope minus cervical lordosis, and ending instrumentation above T4. Significant improvements in health-related quality of life scores occurred despite the development of postoperative CD.Level of evidence
2.Item Open Access Predicting future suicidal events in adolescents using the Concise Health Risk Tracking Self-Report (CHRT-SR).(Journal of psychiatric research, 2020-07) Mayes, Taryn L; Killian, Michael; Rush, A John; Emslie, Graham J; Carmody, Thomas; Kennard, Betsy D; Jha, Manish K; King, Jessica; Hughes, Jennifer L; Trivedi, Madhukar HBackground
Several self-report rating scales have been developed to assess suicidal ideation, yet most have limited utility in predicting future suicide attempts. This is particularly critical in adolescence, where suicide is the second leading cause of death. This study evaluated the Concise Health Risk Tracking Self-Report (CHRT-SR) as a prospective predictor of suicide attempts and events in high-risk adolescents enrolled in a suicide-prevention intensive outpatient program (IOP).Methods
Data were collected by retrospective chart review of adolescents treated in IOP for youth with severe suicidality. At baseline, youth completed the 14-item CHRT-SR (CHRT-SR14), which assesses suicide risk based on 3 subscales: Propensity, Impulsivity, and Suicidal Thoughts. Two outcomes were assessed: actual suicide attempts and suicidal events (suicide attempt, inpatient hospitalization, or emergency department visit) during the IOP.Results
Of the 251 adolescents who completed the baseline CHRT-SR14, 26 had a suicidal event during IOP (mean time in IOP: 5.4 ± 2.3 weeks), of whom 14 had an actual suicide attempt. Youth with any suicidal event had higher scores than those without an event on the CHRT-SR14 Total (p = .005), Propensity (p = .008), and Suicidal Thoughts (p = .001) scales at baseline. Youth who made a suicide attempt had significantly higher scores than those without an event for the Total Score, Propensity, and Suicidal Thoughts subscales. CHRT-SR14 Total Score of 28 had a sensitivity of 85.7% and specificity of 56.5% in predicting suicide attempts. A score of 22 predicted suicidal events, with a sensitivity of 80.8% and specificity of 40.9%. CHRT-SR7 Total Score of 12 predicted suicide attempts, with a sensitivity of 85.7% and specificity of 53.4%.Conclusions
The CHRT-SR14 self-report predicts suicide attempts and events with at least 80% sensitivity and acceptable specificity in adolescents at high-risk for suicide.
