Item Adult Comorbidity Evaluation 27 score as a predictor of survival in endometrial cancer patients(Elsevier, 2016-12) BINDER, Pratibha S; PEIPERT, Jeffrey F; KALLOGJERI, D; BROOKS, Rebecca A; MASSAD, Leslie S; MUTCH, David G; POWELL, Matthew A; THAKER, Premal H; McCOURT, Carolyn K; Obstetrics and Gynecology, School of MedicineBACKGROUND The incidence of endometrial cancer increases with age and is associated with medical comorbidities such as obesity and diabetes. While a few cohort studies of less than 500 patients showed an association between comorbidity and survival in endometrial cancer patients, the degree of association needs to be better described. The Adult Comorbidity Evaluation 27 (ACE-27) is a validated comorbidity instrument that provides a score (0–3) based on the number and severity of medical comorbidities. OBJECTIVE This study was performed to explore the association between medical comorbidities and survival of endometrial cancer patients. STUDY DESIGN Patients diagnosed with endometrial cancer from 2000–2012 were identified from the prospectively maintained Siteman Cancer Center tumor registry. Patients undergoing primary surgical treatment for endometrioid, serous and clear cell endometrial carcinoma were included. Patients primarily treated with radiation, chemotherapy or hormone therapy were excluded. Patients with uterine sarcomas or neuroendocrine tumors were excluded. Patients with missing ACE-27 scores were also excluded from analysis. Information including patient demographics, ACE-27 score, tumor characteristics, adjuvant treatment and survival data were extracted from the database. The association of ACE-27 and overall as well as recurrence-free survival was explored in a multivariable Cox regression analysis after controlling for variables found to be significantly associated with survival in univariable analysis. RESULTS A total of 2073 patients with a median age of 61 years (range 20–94) at diagnosis were identified. ACE-27 score was 0, 1, 2 and 3 in 22%, 38%, 28% and 12% of patients, respectively. Stage distribution was I (73%), II (5%), III (15%) and IV (7%) and grade distribution was 1 (52%), 2 (23%) and 3 (25%). Most patients had endometrioid histology (87%) followed by serous (11%) and clear cell (3%). The median OS for the entire cohort was 54 months [95% confidence interval (CI) 3, 154 months] and median PFS was 50 months [95% CI 2, 154 months]., On univariable analysis, age, race, marital status, stage, grade, histology and treatment type were significantly associated with overall survival and recurrence-free survival. After adjusting for these covariates, patients with ACE-27 score of 2 had a 52% higher risk of death [95% CI 1.16, 2.00] and patients with ACE-27 score of 3 had a 2.35-fold increased risk of death [95% CI 1.73, 3.21] compared to patients with an ACE-27 score of 0. Similarly, patients with ACE-27 score of 2 had a 38% higher risk of recurrence [95% CI 1.07, 1.78] and patients with ACE-27 score of 3 had a 2.05-fold increased risk of recurrence [95% CI 1.53, 2.75] compared to patients with an ACE-27 score of 0. We found no interaction between ACE-27 score and age, stage or treatment type. CONCLUSIONS Our findings demonstrate the importance of comorbidities in estimating the prognosis of endometrial cancer patients, even after adjusting for age and known tumor-specific prognostic factors like stage, grade, histology and adjuvant treatment.Item Comorbidity Profile and Health Care Utilization in Elderly Patients with Serious Mental Illnesses(Elsevier, 2013-12) Hendrie, Hugh C.; Hay, Don; Lane, Kathleen A.; Gao, Sujuan; Purnell, Christianna; Munger, Stephanie; Smith, Faye; Dickens, Jeanne; Boustani, Malaz A.; Callahan, Christopher M.; Department of Psychiatry, IU School of MedicineObjectives Patients with serious mental illness are living longer. Yet there remain few studies that focus on health care utilization and its relationship to comorbidities in these elderly mentally ill patients. Design Comparative study. Information on demographics, comorbidities and health care utilization were taken from an electronic medical record system. Setting Wishard Health Services senior care and community mental health clinics. Participants Patients age 65 years and over-255 patients with serious mental illness (schizophrenia, major recurrent depression and bipolar illness) attending a mental health clinic and a representative sample of 533 non-demented patients without serious mental illness attending primary care clinics. Results Patients having serious mental illness had significantly higher rates of medical emergency room visits (p=0.0027) and significantly longer lengths of medical hospitalizations (p<0.0001) than did the primary care control group. The frequency of medical comorbidities such as diabetes, coronary artery disease, congestive heart failure, chronic obstructive pulmonary disease, thyroid disease, and cancer were not significantly different between the groups. Hypertension was lower in the mentally ill group (p<0.0001). Reported falls (p<0.0001), diagnoses of substance abuse (p=0.02), and alcoholism (p=0.0016) were higher in the seriously mentally ill. The differences in health care utilization between the groups remained significant after adjusting for comorbidity levels, lifestyle factors, and attending primary care. Conclusions Our findings of higher rates of emergency care, longer hospitalizations, and increased frequency of falls, substance abuse, and alcoholism suggest the elderly seriously mentally ill remain a vulnerable population requiring an integrated model of health care.Item Cue-Dependent Inhibition in Posttraumatic Stress Disorder and Attention- Deficit/Hyperactivity Disorder(Elsevier, 2017-10) Adams, Zachary W.; Meinzer, Michael; Mandel, Howard; Voltin, Joshua; Caughron, Blaine; Sallee, Floyd R.; Hmner, Mark; Wang, Zhewu; Department of Psychiatry, School of MedicineObjective Attention-deficit/hyperactivity disorder (ADHD) and posttraumatic stress disorder (PTSD) are common among military veterans, but the comorbidity of these two psychiatric disorders remains largely unstudied. Evaluating response inhibition and cue-dependent learning as behavioral and neurocognitive mechanisms underlying ADHD/PTSD can inform etiological models and development of tailored interventions. Method A cued go/no-go task evaluated response inhibition in 160 adult males. Participants were recruited from the community and a Veterans Administration medical center. Four diagnostic groups were identified: ADHD-only, PTSD-only, ADHD + PTSD, controls. Results Group differences were observed across most indices of inhibitory functioning, reaction time, and reaction time variability, whereby PTSD-only and ADHD + PTSD participants demonstrated deficits relative to controls. No cue dependency effects were observed. Conclusion Finding complement prior work on neurocognitive mechanisms underlying ADHD, PTSD, and ADHD + PTSD. Lack of expected group differences for the ADHD-only group may be due to limited power. Additional work is needed to better characterize distinctions among clinical groups, as well as to test effects among women and youth.Item Development and initial testing of the self‐care of chronic illness inventory(Wiley, 2018-10) Riegel, Barbara; Barbaranelli, Claudio; Sethares, Kristen A.; Daus, Marguerite; Moser, Debra K.; Miller, Jennifer L.; Haedtke, Christine A.; Feinberg, Jodi L.; Lee, Solim; Stromberg, Anna; Jaarsma, Tiny; School of NursingAim The aim was to develop and psychometrically test the self‐care of chronic illness Inventory, a generic measure of self‐care. Background Existing measures of self‐care are disease‐specific or behaviour‐specific; no generic measure of self‐care exists. Design Cross‐sectional survey. Methods We developed a 20‐item self‐report instrument based on the Middle Range Theory of Self‐Care of Chronic Illness, with three separate scales measuring Self‐Care Maintenance, Self‐Care Monitoring, and Self‐Care Management. Each of the three scales is scored separately and standardized 0–100 with higher scores indicating better self‐care. After demonstrating content validity, psychometric testing was conducted in a convenience sample of 407 adults (enrolled from inpatient and outpatient settings at five sites in the United States and ResearchMatch.org). Dimensionality testing with confirmatory factor analysis preceded reliability testing. Results The Self‐Care Maintenance scale (eight items, two dimensions: illness‐related and health‐promoting behaviour) fit well when tested with a two‐factor confirmatory model. The Self‐Care Monitoring scale (five items, single factor) fitted well. The Self‐Care Management scale (seven items, two factors: autonomous and consulting behaviour), when tested with a two‐factor confirmatory model, fitted adequately. A simultaneous confirmatory factor analysis on the combined set of items supported the more general model. Conclusion The self‐care of chronic illness inventory is adequate in reliability and validity. We suggest further testing in diverse populations of patients with chronic illnesses.Item Does comorbid chronic pain affect posttraumatic stress disorder diagnosis and treatment? Outcomes of posttraumatic stress disorder screening in Department of Veterans Affairs primary care(2016) Outcalt, Samantha D.; Hoen, Helena Maria; Yu, Zhangsheng; Franks, Tenesha Marie; Krebs, Erin E.; Department of Psychiatry, IU School of MedicineBecause posttraumatic stress disorder (PTSD) is both prevalent and underrecognized, routine primary care-based screening for PTSD has been implemented across the Veterans Health Administration. PTSD is frequently complicated by the presence of comorbid chronic pain, and patients with both conditions have increased symptom severity and poorer prognosis. Our objective was to determine whether the presence of pain affects diagnosis and treatment of PTSD among Department of Veterans Affairs (VA) patients who have a positive PTSD screening test. This retrospective cohort study used clinical and administrative data from six Midwestern VA medical centers. We identified 4,244 VA primary care patients with a positive PTSD screen and compared outcomes for those with and without a coexisting pain diagnosis. Outcomes were three clinically appropriate responses to positive PTSD screening: (1) mental health visit, (2) PTSD diagnosis, and (3) new selective serotonin reuptake inhibitor (SSRI) prescription. We found that patients with coexisting pain had a lower rate of mental health visits than those without pain (hazard ratio: 0.889, 95% confidence interval: 0.821–0.962). There were no significant differences in the rate of PTSD diagnosis or new SSRI prescription between patients with and without coexisting pain.Item An exploration of concomitant psychiatric disorders in children with autism spectrum disorder(Elsevier, 2019-01) Lecavalier, Luc; McCracken, Courtney E.; Aman, Michael G.; McDougle, Christopher J.; McCracken, James T.; Tierney, Elaine; Smith, Tristram; Johnson, Cynthia; King, Bryan; Handen, Benjamin; Swiezy, Naomi B.; Arnold, L. Eugene; Bearss, Karen; Vitiello, Benedetto; Scahill, Lawrence; Psychiatry, School of MedicineObjective We explored patterns of concomitant psychiatric disorders in a large sample of treatment-seeking children and adolescents with autism spectrum disorder (ASD). Methods Participants were 658 children with ASD (age 3–17 years; mean = 7.2 years) in one of six federally-funded multisite randomized clinical trials (RCT) between 1999 and 2014. All children were referred for hyperactivity or irritability. Study designs varied, but all used the Child and Adolescent Symptom Inventory or Early Childhood Inventory to assess Attention Deficit Hyperactivity Disorder (ADHD), Oppositional-Defiant Disorder (ODD), Conduct Disorder (CD), Anxiety Disorders, and Mood Disorders. In addition, several measures in common were used to assess demographic and clinical characteristics. Results Of the 658 children, 73% were Caucasian and 59% had an IQ >70. The rates of concomitant disorders across studies were: ADHD 81%, ODD 46%, CD 12%, any anxiety disorder 42%, and any mood disorder 8%. Two or more psychiatric disorders were identified in 66% of the sample. Of those who met criteria for ADHD, 50% also met criteria for ODD and 46% for any anxiety disorder. Associations between types of concomitant disorders and a number of demographic and clinical characteristics are presented. Conclusion In this well-characterized sample of treatment-seeking children with ASD, rates of concomitant psychiatric disorders were high and the presence of two or more co-occurring disorders was common. Findings highlight the importance of improving diagnostic practice in ASD and understanding possible mechanisms of comorbidity.Item Medication-taking behaviours in chronic kidney disease with multiple chronic conditions: a meta-ethnographic synthesis of qualitative studies(Wiley, 2017-03) Bartlett Ellis, Rebecca J.; Welch, Janet L.; IU School of NursingAims and objectives To identify behaviours associated with taking medications and medication adherence reported in qualitative studies of adults with chronic kidney disease and coexisting multiple chronic conditions. Background To inform medication adherence interventions, information is needed to clarify the nature of the relationships between behaviours that support medication-taking and medication adherence in multiple chronic conditions. Design Meta-ethnographic review and synthesis. Methods CINAHL Complete, MEDLINE and PsycINFO databases were searched. Five qualitative studies met the inclusion criteria. A meta-ethnographic approach was used for synthesis. Medication-taking behaviours were abstracted from study findings and synthesised according to the contexts in which they occur and interpreted within a new developing framework named the Medication-taking Across the Care Continuum and Adherence-related Outcomes. Results Twenty categories of medication-taking behaviours occurred in three main contexts: (1) patient–provider clinical encounters, (2) pharmacy encounters and (3) day-to-day management. These behaviours are distinctly different, multilevel and interrelated. Together they represent a process occurring across a continuum. Conclusions Future medication adherence research should consider using a multilevel ecological view of medication management. Clinical practice and policy development can benefit from further understanding socio-contextual behaviours that occur across the continuum. Nurses should have greater presence in chronic disease management and be positioned to support the day-to-day home management of patients' medications.Item Polysubstance addiction vulnerability in mental illness: Concurrent alcohol and nicotine self‐administration in the neurodevelopmental hippocampal lesion rat model of schizophrenia(Wiley, 2019) Sentir, Alena; Bell, Richard L.; Engleman, Eric A.; Chambers, R. Andrew; Psychiatry, School of MedicineMultiple addictions frequently occur in patients with mental illness. However, basic research on the brain‐based linkages between these comorbidities is extremely limited. Toward characterizing the first animal modeling of polysubstance use and addiction vulnerability in schizophrenia, adolescent rats with neonatal ventral hippocampal lesions (NVHLs) and controls had 19 weekdays of 1 hour/day free access to alcohol/sucrose solutions (fading from 10% sucrose to 10% alcohol/2% sucrose on day 10) during postnatal days (PD 35‐60). Starting in adulthood (PD 63), rats acquired lever pressing for concurrent oral alcohol (10% with 2% sucrose) and iv nicotine (0.015 mg/kg/injection) across 15 sessions. Subsequently, 10 operant extinction sessions and 3 reinstatement sessions examined drug seeking upon withholding of nicotine, then both nicotine and alcohol, then reintroduction. Adolescent alcohol consumption did not differ between NVHLs and controls. However, in adulthood, NVHLs showed increased lever pressing at alcohol and nicotine levers that progressed more strongly at the nicotine lever, even as most pressing by both groups was at the alcohol lever. In extinction, both groups showed expected declines in effort as drugs were withheld, but NVHLs persisted with greater pressing at both alcohol and nicotine levers. In reinstatement, alcohol reaccess increased pressing, with NVHLs showing greater nicotine lever activity overall. Developmental temporal‐limbic abnormalities that produce mental illness can thus generate adult polydrug addiction vulnerability as a mechanism independent from putative cross‐sensitization effects between addictive drugs. Further preclinical modeling of third‐order (and higher) addiction‐mental illness comorbidities may advance our understanding and treatment of these complex, yet common brain illnesses.Item Retrospective Chart Review Comparing CKD COVID-19 Positive Patient Outcomes to non-CKD Patient Outcomes(Indiana University, 2020) Eckert, Nicole; Sankari, Safiya; Allen, Katie; Hui, Siu Lui; Mendonca, Eneida; Health Policy and Management, School of Public HealthBackground/Objective: Since January 2020, there have been over 3 million individuals infected with the coronavirus in the United States, quickly spreading across at least 171 countries. The severity and morbidity of patients with COVID-19 are significantly increased when comorbidities, such as Chronic Kidney Disease (CKD), are present. Because the main target of SARS-CoV-2 is ACE2, patients with CKD may be a more vulnerable population. The goal of this study was to determine if COVID-19 positive patients with CKD had increased mortality, inpatient admission, and ED visitation rates compared to those without CKD. Methods: This retrospective chart review includes patients from over 100 separate healthcare entities who were diagnosed with COVID-19 between January 1, 2020 and July 13, 2020 and are over the age of 18. The subjects were first separated into those diagnosed with CKD and those without, basic descriptive calculations were computed, and a Chi Square test was used to analyze outcomes. Results: The CKD COVID-19 positive population was compromised of 47.5% men and 52.5% women while the non-CKD control group was made up of 45.4 % men, 54.1% women, and 0.5% other. The median Charlson index for the CKD and non-CKD population was 4 and 1, respectively. The interest and control groups were further divided into subpopulations by age and race and analyzed accordingly. Chi square tests demonstrated that there is a statistically significant difference (p<0.05) in all clinical outcomes tested of CKD patients diagnosed with COVID-19 compared to non-CKD patients. The CKD population had increased mortality, inpatient admission, and ED visitation rates when compared. Discussion: This study demonstrates that comorbidities, more specifically CKD, may be associated with a higher severity of COVID-19 than those without. Future studies are needed to explore the relationship more extensively, analyze other outcomes, and manage confounding variables.Item Using Patterns of Genetic Association to Elucidate Shared Genetic Etiologies Across Psychiatric Disorders(Springer, 2017-07) Cho, Seung Bin; Aliev, Fazil; Clark, Shaunna L.; Adkins, Amy E.; Edenberg, Howard J.; Bucholz, Kathleen K.; Porjesz, Bernice; Dick, Danielle M.; Biochemistry and Molecular Biology, School of MedicineTwin studies indicate that latent genetic factors overlap across comorbid psychiatric disorders. In this study, we used a novel approach to elucidate shared genetic factors across psychiatric outcomes by clustering single nucleotide polymorphisms based on their genome-wide association patterns. We applied latent profile analysis (LPA) to p-values resulting from genome-wide association studies across three phenotypes: symptom counts of alcohol dependence (AD), antisocial personality disorder (ASP), and major depression (MD), using the European–American case-control genome-wide association study subsample of the collaborative study on the genetics of alcoholism (N = 1399). In the 3-class model, classes were characterized by overall low associations (85.6% of SNPs), relatively stronger association only with MD (6.8%), and stronger associations with AD and ASP but not with MD (7.6%), respectively. These results parallel the genetic factor structure identified in twin studies. The findings suggest that applying LPA to association results across multiple disorders may be a promising approach to identify the specific genetic etiologies underlying shared genetic variance.
