Abstract
OBJECTIVE To determine the association between disease activity and choroidal thickness in patients with systemic lupus erythematosus (SLE). METHODS We conducted a cohort study of 24 SLE patients and 13 healthy controls recruited at Washington University School of Medicine between June 2019 and November 2021. SLE disease activity was assessed using the SLE Disease Activity Index-2000 Responder Index-50 (S2K RI-50). Patients were divided into four groups: high disease activity/no lupus nephritis (HDA/no LN; S2K RI-50 > 4), HDA/active LN (HDA/active LN; S2K RI-50 > 4), low disease activity/inactive LN (LDA/inactive LN; S2K RI-50 ≤ 4), and LDA/no LN (LDA/no LN; S2K RI-50 ≤ 4). LDA/no LN patients were age-, sex-, and race-matched to healthy controls and patients in other SLE groups. Choroidal thickness of the right eye was measured blinded to disease activity on a horizontal section through the fovea on optical coherence tomography images taken within a week of disease assessment. RESULTS Patients with HDA had choroidal thickening compared with matched patients with LDA. After controlling for multiplicity, choroidal thinning remained statistically significant at 1000 μm nasal to the fovea (308 ± 68 vs 228 ± 64 μm, p = 0.001). Choroidal thickness was not different between LDA/no LN and LDA/inactive LN or healthy controls. CONCLUSION HDA in patient with SLE is associated with increased choroidal thickness whereas comorbid inactive LN did not affect choroidal thickness. Additional studies in a larger longitudinal cohort are needed to study whether choroidal thickness may be used as a noninvasive, adjunctive measure for disease activity in SLE.

Abstract
ABSTRACT The workforce shortage of musculoskeletal and rheumatic disease (MSK-RMD) trained providers has led to the need for additional education for nurse practitioners (NPs) in MSK-RMD. An educational certificate was developed and implemented collaboratively between an academic medical center and a college of nursing. The NP-focused MSK-RMD education program enhanced the assessment and treatment of a variety of common RSK-RMD conditions. Interviews and online surveys were conducted with participants to evaluate the program experience. Participant interviews and survey findings demonstrate overall NP satisfaction with the program. Expanding the program to create an accessible virtual continuing education course may improve accessibility of MSK-RMD education for NPs in primary care and multidisciplinary environments.

Abstract
Pelvic fragility fractures result in significant morbidity and their incidence has increased over the past 30 years. One of the main risk factors in skeletal fragility is bone mineral density (BMD). Most of the current literature has focused on understanding spine and hip BMD. We aimed to measure the BMD of pelvis in a cohort of post-menopausal women and compare it to BMD at other skeletal sites. A questionnaire regarding risk factors for osteoporosis was completed by each participant. DXA scan of the pelvis was performed using research software. Three areas of the pelvis corresponding to common fractures were defined on pelvic DXA: R1 = symphysis public, R2 = inferior public rami, R3 = superior public rami. Pelvic BMD was calculated as the average BMD of R1-3. BMD at each location was reported as mean and standard deviation (SD). ANOVA was used to compare BMD between R1-R3 and pelvis, femoral neck, total hip, and spine. Pearson correlation was used to correlate pelvic BMD to BMD of proximal femur and spine. BMD was compared in four participant groups: 1- osteoporosis in spine and hip, 2- osteoporosis in spine only, 3-osteoporosis in hip only, and 4- no osteoporosis in spine and hip. The effect of diabetes and obesity on BMD at various skeletal sites was analyzed. Among the one hundred postmenopausal women enrolled in the study, age was: 64 ± 8, 31% were obese (BMI ≥ 30), and 8% had a diagnosis of type 2 diabetes. Pelvic area R3 had significantly higher BMD than R1 or R2 (p < 0.001). Pelvic BMD (0.50 ± 0.16) was significantly lower than total hip (0.70 ± 0.20) and spine BMD (0.97 ± 0.19) (p < 0.001). Pelvic BMD correlated with BMD at other skeletal locations, with the highest correlation with total hip (total hip: R2: 0.70, femoral neck R2: 0.50, spine R2: 0.65). Pelvic BMD was significantly lower in patients with osteoporosis of both hip and spine compared to the group without osteoporosis at both locations (p = 0.02). Obesity and type 2 diabetes were both associated with significantly higher BMD at pelvis, spine, and total hip. Pelvic BMD is lower than at other skeletal sites and is highly correlated with total hip area bone density. Obesity and type 2 diabetes are associated with higher pelvic BMD. To establish guidelines for the treatment pelvic BMD, studies defining the association of pelvic BMD with pelvic fracture risk are needed.

Abstract
Objective The objectives of this study are to identify patterns of anxiety symptomology over time among patients with systemic lupus erythematosus (SLE) and to assess the longitudinal relationship between SLE disease activity and anxiety symptomology. Methods Longitudinal data from 139 patients with American College of Rheumatology or Systemic Lupus International Collborating Clinic (SLICC)‐classified SLE were analyzed. Anxiety symptomology was assessed using the Patient‐Reported Outcomes Measurement Information System (PROMIS) Emotional Distress: Anxiety Short Form 8a. SLE disease activity was measured using the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)‐2000 (S2K) and S2K Responder Index 50 (S2K RI‐50). Group‐based trajectory modeling (GBTM) identified longitudinal trajectories of anxiety symptomology. The relationship between disease activity and anxiety over time was assessed using multilevel linear regressions. Results The mean patient age was 40.2 years (standard deviation [SD], 12.7); 90.6% were female, and 56.1% were of Black race. All patients had at least three PROMIS anxiety scores over an average of 30.9 months (SD, 13.0). GBTM identified four trajectories of anxiety symptomology, labeled as the following: low (LA), average (AA), moderate (MA), and high anxiety (HA). Black patients were 2.47 (95% confidence interval: 1.19‐5.12) times as likely as White patients to be classified into the MA or HA groups compared with the LA or AA groups. On multivariable analysis, active SLE disease was not significantly associated with anxiety over time (P = 0.19). Conclusion Anxiety trajectories remained stable over time, and racial differences in anxiety severity were observed. SLE disease activity was not longitudinally associated with anxiety after controlling for depression and other factors. Further understanding of the factors that contribute to the persistence of anxiety among individuals with SLE is necessary.

Abstract
OBJECTIVE Depression is a prevalent (24-30%) and significant comorbidity in patients with systemic lupus erythematosus (SLE). In the present study, we leveraged the longitudinal SLE cohort at the Washington University Lupus Clinic to address: 1) what is the longitudinal course of depressed affect among outpatients with SLE? 2) what is the longitudinal relationship between SLE disease activity and depressed affect? METHODS Longitudinal data from patients with ACR or Systemic Lupus International Collaborating Clinics (SLICC)-classified SLE were analyzed. Depressed symptoms were assessed at each visit using the Center for Epidemiologic Studies Depression Scale, Revised (CESD-R) while SLE disease activity was measured via the SLEDAI2K Responder Index-50 (S2K RI-50). Group-based trajectory modeling (GBTM) and linear mixed models were used for analysis. RESULTS The sample (n=144) was 56.3% Black, and 38.9% White. GBTM revealed five distinct groups of patients who demonstrated consistent trends in depression overtime. Members of groups 4 (n=44, 30.6%) and 5 (n=44, 30.6%) demonstrated CESD-R scores consistent with depression. Of note, Black patients were much more common in Group 5 (n=32, 72.7%, p<0.02). Analyses identified an association between SLEDAI disease activity and depression scores in multivariate analysis but did not show significance in GBTM and univariate analysis. CONCLUSIONS The majority (61.2%) of patients had CESD-R scores consistent with persistent depressed affect or major depression over a period of up to four years. The lack of a consistent relationship of CESD-R with SLE disease activity highlights the need to regularly monitor, treat and better understand the causes behind this comorbidity.

Abstract
BACKGROUND Urate-lowering therapy (ULT) adherence is low in gout, and few, if any, effective, low-cost, interventions are available. Our objective was to assess if a culturally appropriate gout-storytelling intervention is superior to an attention control for improving gout outcomes in African-Americans (AAs). METHODS In a 1-year, multicenter, randomized controlled trial, AA veterans with gout were randomized to gout-storytelling intervention vs. a stress reduction video (attention control group; 1:1 ratio). The primary outcome was ULT adherence measured with MEMSCap™, an electronic monitoring system that objectively measured ULT medication adherence. RESULTS The 306 male AA veterans with gout who met the eligibility criteria were randomized to the gout-storytelling intervention (n = 152) or stress reduction video (n = 154); 261/306 (85%) completed the 1-year study. The mean age was 64 years, body mass index was 33 kg/m2, and gout disease duration was 3 years. ULT adherence was similar in the intervention vs. control groups: 3 months, 73% versus 70%; 6 months, 69% versus 69%; 9 months, 66% versus 67%; and 12 months, 61% versus 64% (p > 0.05 each). Secondary outcomes (gout flares, serum urate and gout-specific health-related quality of life [HRQOL]) in the intervention versus control groups were similar at all time points except intervention group outcomes were better for the following: (1) number of gout flares at 9 months were fewer, 0.7 versus 1.3 in the previous month (p = 0.03); (2) lower/better scores on two gout specific HRQOL subscales: gout medication side effects at 3 months, 32.8 vs. 39.6 (p = 0.02); and unmet gout treatment need at 3 months, 30.9 vs. 38.2 (p = 0.003), and 6 months, 29.5 vs. 34.5 (p = 0.03), respectively. CONCLUSIONS A culturally appropriate gout-storytelling intervention was not superior to attention control for improving gout outcomes in AAs with gout.

Abstract
INTRODUCTION Peripheral neuropathy occurs in two thirds of patients with diabetes mellitus (DM). It can lead to severe pathological changes in the feet, and it increases the risk of fracture more than any other diabetic complication. The objective of this review is to analyze available literature on the effect of peripheral neuropathy on BMD of the foot, spine, or hip. We hypothesize that the presence of diabetic neuropathy leads to lower BMD in adults with diabetes. METHODS Original studies investigating the effects of diabetic neuropathy on bone density were searched for inclusion in this systematic review. Studies were eligible if they met the following criteria: 1) participants included adults with either Type 1 DM or Type 2 DM; 2) Method used for the diagnosis of neuropathy described in the manuscript 3) DXA scan, ultrasound, or CT scan was used to measure proximal femur, spine, or foot bone mineral density were reported, and 4) bone parameters were analyzed based on the presence and absence of neuropathy. RESULTS Among the 5 studies that met eligibility criteria, 4 did not find a significant effect of neuropathy on BMD. One study showed a significant negative impact of neuropathy on calcaneal BMD in patients with type 1 diabetes. The meta-analysis did not show a significant effect of peripheral neuropathy on BMDs of proximal femur, spine, and calcaneus in diabetic adults. CONCLUSION Our study shows no evidence that peripheral neuropathy affects bone density or bone turnover in DM. However, this conclusion should be taken with caution since only a very limited number of studies were available for inclusion in the analysis and included both type 1 and type 2 DM patients. Improved measures of peripheral neuropathy and more advanced imaging technologies are needed to better assess the effect of diabetes on bone health.

Abstract
Background:The Department of Veterans Affairs (DVA) provides comprehensive medical care at minimal or no cost to 9 million veterans annually through 170 medical centers and 1074 outpatient clinics across the United States. In 1999, the DVA established a national, fully integrated electronic health record (EHR), which now includes approximately 24 million veterans. However, few studies have used VA EHR data to examine the validity of diagnoses of rheumatoid arthritis (RA).Objectives:Develop a validated, national database (VANRAD) of patients with RA who received VA care since International Classification of Diseases, tenth revision (ICD-10) coding was introduced in 2015. The database will provide infrastructure for retrospective and prospective research to address the ‘real-world’ care of patients with RA.Methods:Patients with the following criteria were identified from the VA EHR as of October 2, 2020: (a) ≥1 ICD-10 diagnosis code of RA; (b) treatment with ≥1 disease-modifying anti-rheumatic drug (DMARD); (c) ≥2 VA rheumatology clinic visits; and (d) ≥1 rheumatoid factor (RF) or anti-cyclic citrullinated peptide (aCCP) antibody test result. From this group, 553 EHRs were randomly selected for review. The ‘gold standard’ for the diagnosis of RA was the treating rheumatologist’s diagnosis, documented in the EHR.Results:27,482 patients met eligibility criteria. Sociodemographic characteristics were: 85.6% male, mean age of 69.7 years (y) (SD=10.9 y; range=21.9 y to 100.5 y), 76.4% white, 17.0% African American; and mean VA care duration 14.1 y (SD=5.3 y, range=0.04 y to 20.0 y).For patients with ≥1 RF or aCCP test, the positive predictive value (PPV) for RA ranged from 65.3% (aCCP-/RF-) to 95.8% (aCCP+/RF+); rheumatologists’ likelihood of a ‘possible’ diagnosis was higher if the aCCP test result was negative or not available (Table 1). Excluding patients with a second rheumatologic diagnosis did not improve PPV results (data not shown).Table 1.Proportion of patients with a valid RA diagnosis1 as a function of RF and aCCP laboratory resultsTest ResultaCCPNot Available (0)2Negative (-)Positive (+)TotalRheumatoid FactorNot Available (0)(N = 1253)3N 427N 1,159N 1,586RA4 89.7%RA 98.2%RA 93.5%Poss5 RA 5.9%Poss RA 0.0%Poss RA 3.2%Negative (-)N 810N 5,308N 2,005N 8,123RA 86.3%RA 65.3%RA 94.5%RA 80.7%Poss RA 3.9%Poss RA 11.9%Poss RA 0.0%Poss RA 5.8%Positive (+)N 2,229N 2,566N 12,978N 17,773RA 94.6%RA 78.0%RA 95.8%RA 87.6%Poss RA 0.0%Poss RA 8.5%Poss RA 2.1%Poss RA 4.3%TotalN 3,039N 8.301N 16,142N 27,482RA 90.7%RA 76.1%RA 95.9%RA 85.9%Poss RA 1.9%Poss RA 9.2%Poss RA 0.5%Poss RA 4.7%1Diagnosis given by the treating rheumatologist.2No test results available or test results available but without normal range values.31,253 patients without available or interpretable RF or aCCP excluded from initial cohort.4Percent of 553 charts reviewed confirmed as RA.5Poss RA = Possible RA. Patients met our inclusion criteria but the treating rheumatologist never made definitive diagnosis of RA or alternative diagnosis (from 553 charts reviewed).The percentage of RA-confirmed patients with one test not available, whose complementary test was negative (RF0/aCCP- or RF-/aCCP0), was greater than of patients for whom both tests were negative (RF-/aCCP-). This suggests our data extraction methods may be incomplete or that unidentified bias may be present and warrants further study.Conclusion:Our methodology for constructing an RA database by selecting patients with ≥2 rheumatology clinic visits, ≥1 ICD-10 diagnosis of RA, and treatment with ≥1 DMARD, has high positive predictive value for RA. Positive RF and aCCP test results were strong predictors of rheumatologists’ diagnostic certainty for an RA diagnosis. Thus, the VANRAD database and the associated EHR provide opportunity for a wide range of retrospective observational and prospective longitudinal studies based on ‘real-world’ patient care.References:[1]Ng B, et al.

Abstract
5032 Background: Abiraterone (AA) and enzalutamide (ENZ) are two second generation antiandrogens used to treat advanced prostate cancer, but no large head-to-head trials have been performed. These oral therapies are commonly used in older patients with medical comorbidities who are not candidates for chemotherapy or clinical trials and have different mechanisms of action, adverse events, and drug interactions. To understand survival of patients with prostate cancer, we studied United States veterans treated prior to approval of AA and ENZ for metastatic hormone sensitive prostate cancer when both drugs had approval for metastatic castration resistant prostate cancer. Methods: We identified patients treated with AA or ENZ between 9/10/2014 and 6/3/2017 in the Veterans Health Administration and followed them to April 2020. Age, Elixhauser comorbidity score, treatment with androgen deprivation therapy (ADT) and docetaxel were collected. Cox proportional hazards modeling was used to assess the association between first oral treatment (AA or ENZ) and overall survival, while adjusting for covariates. Results: Of 5895 patients, 2562 (43.5%) were initially treated with ENZ, 3333 (56.5%) with AA, and 3040 (51.6%) received only one of the two drugs during the study period. Patients initially treated with ENZ compared to AA were older (mean 75.9 vs. 75.0 years, p = 0.001), had higher mean comorbidity score (6.2 vs. 5.9, p < 0.001), and were less likely to receive both ENZ and AA (45.2% vs. 51.0%, p < 0.001) or docetaxel (24.1% vs. 28.4%, p < 0.001). Patients who received only AA or ENZ and never received docetaxel were older (mean 78.3 vs. 73.2 years, p < 0.001) with higher mean comorbidity scores (6.4 vs. 5.7, p < 0.001). In the entire cohort, initial treatment with ENZ was associated with longer median survival (24.1 vs. 22.2 months, p = 0.003). After adjusting for age and comorbidities, ENZ was associated with a decreased risk of death compared to AA (HR 0.87, 95% CI 0.82-0.92). In 3317 patients who received two or more therapies (ENZ, AA, docetaxel) there was no difference in median survival between initial treatment with ENZ or AA (28.0 vs. 27.9 months). In 2578 patients (43.7%) who never received docetaxel and either ENZ or AA only, median survival was longer in patients treated with ENZ (18.9 vs. 13.6 months, p < 0.001) and was associated with decreased mortality when adjusting for age and comorbidities (HR 0.73, 95% CI 0.67-0.80). Conclusions: In the overall cohort, initial treatment with ENZ was associated with increased survival compared to AA. Patients who received only ENZ or AA and never received docetaxel had the largest benefit from ENZ, a difference of 5.3 months median survival. Efforts should be made to improve therapy selection for patients with prostate cancer, especially older patients with comorbidities.

Abstract
OBJECTIVE International Classification of Diseases (ICD) codes are commonly used to identify patients with rare diseases in electronic health records (EHRs). However, misclassification is common, impacting the validity of study results. In this study, we compared the accuracies of several ICD-based case definitions of lupus nephritis (LN) in identifying United States veterans with LN. METHODS Using the Department of Veterans Affairs (VA) EHR, we identified all veterans with ≥1 ICD-9 or 10 diagnostic codes for systemic lupus erythematosus (SLE) between October 1, 1999 and September 30, 2017. A cohort was randomly selected for diagnostic validation and 9 ICD-based LN case definitions were applied to this cohort. The diagnostic accuracy of each definition was assessed against gold standard criterion of biopsy-proven LN. RESULTS 18,420 veterans had ≥1 ICD-9 or 10 diagnostic codes for SLE; 981 were randomly selected for diagnostic validation. 95 veterans (9.7%) had biopsy-proven LN. The case definitions had high specificity and NPV but variable sensitivity and PPV. The definition containing ≥2 ICD -9 codes for SLE and ≥2 nephritis indicators had the highest combination of sensitivity and specificity (87.4% and 94.6% respectively). ICD-10 code for LN had high specificity (99.8%) and PPV (93.9%). CONCLUSION ICD-based case definitions of LN in the VA population have high specificity and NPV but variable sensitivity and PPV. Our results may help guide the design of future LN studies in VA cohorts. The choice of specific case definitions depends on the relative importance of different accuracy measures to individual studies.

Abstract
Pelvic fractures represent 7% of all fragility fractures; they account for 5% of the cost of osteoporotic fracture care, and are commonly (> 50%) associated with loss of independence in the elderly. The incidence of pelvic fractures has increased significantly over the past 3 decades. However, little is known about the relationship between bone mineral density (BMD) and pelvic fractures. We have conducted a pilot cross-sectional study to establish a method of measuring pelvic BMD and to correlate BMD of the pelvis with BMD at other skeletal sites. Postmenopausal women without a history of pelvis and hip fragility fractures were enrolled. Hip, spine, and pelvis DXA scans were obtained using a Hologic DXA machine. Pelvic BMD was calculated using Hologic Research Software from 3 areas of the pelvis (R1: public symphysis, R2: inferior pubic ramus, and R3: superior pubic ramus), corresponding to common fracture locations. Pelvis BMD was the average of the 3 pelvis sites. Pelvic BMD measurement precision error was calculated using the root mean square method (Recommended by International Society of Clinical Densitometry (ISCD)). Statistical analysis was used to compare BMD at different sites. Alpha error was set at 0.05. Of 73 postmenopausal women who were enrolled in the study (average age 64 years, average 15 years postmenopausal), 3% had chronic kidney disease, 7% had type 2 DM, 3% were on corticosteroids and none were smokers. BMD of femoral neck assessed on pelvic DXA was not significantly different from femoral neck BMD measured on standard DXA (P=0.09). To assess pelvis BMD measurement precision, 15 patients underwent 3 separate pelvic DXA images after repositioning. BMD precision error was 0.011g/cm2 which is slightly lower than the precision total hip BMD at our center (0.007 g/cm2). BMD of R1, R2, and R3 pelvic areas were measured as 0.44±0.15, 0.41± 0.15, and 0.62 ±0.19 g/cm2, respectively. Notably, BMD of R3 was significantly higher than the other 2 areas (P<0.001, ANOVA). Average BMD (0.49±0.14 g/cm2) of pelvis was significantly lower than BMD of femoral neck (0.72± 0.16 g/cm2), total hip (0.86±17 g/cm2) and spine (0.97± 19 g/cm2)(P <0.001). Average BMD of pelvis was significantly lower in participants with osteopenia and osteoporosis of the hip and femoral neck compared to participants with normal BMD in those locations. In summary, we report a precise method of measuring BMD of commonly fractured areas of the pelvis. Pelvis BMD is lower than hip, femoral neck, and spine. Bone density of the pelvis correlates with hip and femoral neck bone density. The results of this pilot study can be used for future studies looking at pelvic low bone density in patients with pelvic fragility fractures which could help identify patients at risk for pelvic fragility fractures and change how osteoporosis is defined based on DXA images.

Abstract
OBJECTIVES Although cross-sectional studies have shown that ankylosing spondylitis-specific factors correlate with depressive symptom severity, the association of these factors over time is unresolved. We examined the demographic and clinical factors associated with longitudinal depressive symptom severity in AS patients. METHODS We analyzed sociodemographic, clinical, behavioral and medication data from 991 patients from the Prospective Study of Outcomes in Ankylosing spondylitis cohort, and measured depression severity with the Center for Epidemiological Studies Depression (CES-D) Scale administered at approximately 6-month visit intervals. Multivariable longitudinal negative binomial regression models were conducted using generalized estimating equation modeling to assess the demographic, clinical, and medication-related factors associated with depression severity by CES-D scores over time. RESULTS The median baseline CES-D score (possible range 0-60) was 10.0 (interquartile range = 5, 17). In longitudinal multivariable analyses, higher CES-D scores were associated with longitudinal smoking, greater functional impairment, greater disease activity, self-reported depression, and poor global health scores. Marital status (e.g., being married) was associated with lower CES-D. Adjusted mean CES-D scores in our model decreased over time, with a significant interaction between time and gender observed. CONCLUSION This study identified longitudinal clinical factors such as greater disease activity, greater functional impairment, and poor global health to be associated with longitudinal depression severity. These factors are potentially modifiable and may help manage depressive symptoms in AS.

Abstract
OBJECTIVE This study aimed to compare choroidal thickness between patients with systemic lupus erythematosus (SLE) and lupus nephritis (LN) in complete renal remission to that of patients with SLE without LN. METHODS This was a retrospective case-control study of 23 SLE patients meeting either the American College of Rheumatology or Systemic Lupus International Collaborating Clinics classification criteria and followed at Washington University School of Medicine Rheumatology or Nephrology, and Ophthalmology outpatient clinics. The diagnosis of LN was based on renal pathology, and complete renal remission was defined as proteinuria <500 mg/daily and serum creatinine at baseline. Extra-renal flare status was determined using modified Fortin criteria. Choroidal thickness was measured using spectral-domain optical coherence tomography and read by blinded reviewers. RESULTS In SLE patients without extra-renal flare, choroidal thickness of LN patients was 281 ± 78 µm compared to 288 ± 70 µm in non-LN SLE patients (p = 0.766) at the fovea. CONCLUSION Choroidal thickness was not different in patients with LN in remission compared to non-LN SLE patients in remission. Additional studies are needed to examine choroidal thickness in patients with SLE with active LN.

Abstract
OBJECTIVE To explore gout self-management and associated challenges and solutions in African Americans. METHODS We conducted semistructured interviews with 35 African American veterans with gout, who received health care at Birmingham or Philadelphia Veterans Affairs (VA) medical centers, had filled urate-lowering therapy (ULT; most commonly allopurinol) for at least 6 months, and had a ULT medication possession ratio ≥80%. The interview protocol was constructed to explore key concepts related to gout self-management, including initial diagnosis of gout, beginning medical care for gout, the course of the gout, ULT medication adherence, dietary strategies, comorbidity and side effects, and social support. RESULTS Thirty-five African American male veterans with gout who had ≥80% ULT adherence (most commonly, allopurinol) were interviewed at Birmingham (n = 18) or Philadelphia (n = 17) VA medical centers. Mean age was 65 years, mean body mass index was 31.9 kg/m2 , 97% had hypertension, 23% had coronary artery disease, and 31% had renal failure. The main themes motivating African American veterans to better gout self-management were fear of pain, adherence to medications, self-discipline, lifestyle changes, information gathering, and developing a positive outlook. Birmingham participants more frequently revealed skipping gout medications. More Philadelphia participants discussed lifestyle/diet changes to prevent gout flares, indicated limiting social activities that involved drinking, and sought more information about gout self-management from health care providers and internet sources. CONCLUSION Identified themes, including cultural differences by site, led to the development of a patient-centered intervention to improve gout self-management in African American men with gout.

Abstract
Combat experiences early in adulthood may have lifelong ramifications. In the Vietnam Era Twin Study of Aging (VETSA), the authors studied lifetime educational attainment (LEA) in 236 male twins from the Vietnam Era Twin Registry. Twins who served in Vietnam had completed significantly fewer years of education by their 50s. Level of combat exposure was negatively correlated with LEA. To control for variables that might confound the relationship between combat and LEA, the authors compared twin pairs discordant for Vietnam service ( n = 44 pairs); the twins who served in Vietnam had significantly lower LEA than their cotwins. Greater cognitive ability at military induction and older age at induction both predicted higher LEA, but after statistically controlling for these variables, the relationship between combat exposure and LEA remained significant. The VETSA results demonstrate that combat experience and entering military service at a younger age may reduce lifelong educational prospects, even after cognitive ability is controlled.

Abstract
AbstractThere have been long questions about the relationship of schizophrenia to other mental disorders. Lifetime DSM-III-R diagnoses of mood and anxiety disorders in twins with clinically diagnosed schizophrenia (n = 24) and their non-affected co-twins (n = 24) were compared with twins from pairs without schizophrenia (n = 3327) using a sample from the Vietnam Era Twin Registry. Schizophrenic probands had significantly elevated rates of all included disorders (bipolar disorder, major depression, dysthymia, generalized anxiety disorder, panic disorder, and PTSD) compared with controls (P < 0.01). The odd ratios comparing co-twins of schizophrenic probands with controls was greater than three for every disorder, but did not attain statistical significance. A similar pattern was observed when analyses were restricted to only monozygotic twins (n = 12). Consistent with other studies, schizophrenics appeared to have higher rates of a range of mental disorders. Our results suggest that schizophrenia per se represents a risk factor for other psychiatric disorders, but the absence of significantly elevated risk among non-schizophrenic co-twins suggested that family environmental and/or genetic factors that contribute to risk of schizophrenia do not increase the risk of mood and anxiety disorders to the same extent that the risk of these other disorders is increased by the presence of schizophrenia.

Abstract
The purpose of this paper is to report on the outcomes of the 2010 VA Women's Health Services Research Conference, which brought together investigators interested in pursuing research on women veterans and women in the military with leaders in women's health care delivery and policy within and outside the VA, to significantly advance the state and future direction of VA women's health research and its potential impacts on practice and policy. Building on priorities assembled in the previous VA research agenda (2004) and the research conducted in the intervening six years, we used an array of approaches to foster research-clinical partnerships that integrated the state-of-the-science with the informational and strategic needs of senior policy and practice leaders. With demonstrated leadership commitment and support, broad field-based participation, strong interagency collaboration and a push to accelerate the move from observational to interventional and implementation research, the Conference provided a vital venue for establishing the foundation for a new research agenda. In this paper, we provide the historical evolution of the emergence of women veterans' health services research and an overview of the research in the intervening years since the first VA women's health research agenda. We then present the resulting VA Women's Health Research Agenda priorities and supporting activities designed to transform care for women veterans in six broad areas of study, including access to care and rural health; primary care and prevention; mental health; post deployment health; complex chronic conditions, aging and long-term care; and reproductive health.

Abstract
There is a growing body of evidence on the impact of the environment on health and well-being. This study focuses on the impact of visual artworks on the well-being of psychiatric patients in a multi-purpose lounge of an acute care psychiatric unit. Well-being was measured by the rate of pro re nata (PRN) medication issued by nurses in response to visible signs of patient anxiety and agitation. Nurses were interviewed to get qualitative feedback on the patient response. Findings revealed that the ratio of PRN/patient census was significantly lower on the days when a realistic nature photograph was displayed, compared to the control condition (no art) and abstract art. Nurses reported that some patients displayed agitated behaviour in response to the abstract image. This study makes a case for the impact of visual art on mental well-being. The research findings were also translated into the time and money invested on PRN incidents, and annual cost savings of almost $US30,000 a year was projected. This research makes a case that simple environmental interventions like visual art can save the hospital costs of medication, and staff and pharmacy time, by providing a visual distraction that can alleviate anxiety and agitation in patients.

Abstract
The effect of TNF-α blockade on the risk of cardiovascular outcomes and long-term survival in patients with rheumatoid arthritis (RA) is not known. We assembled a cohort of 20,811 (75,329 person-years) U.S. veterans who were diagnosed with RA between October 1998 and September 2005, and who were treated with a disease-modifying anti-rheumatic drug (DMARD). Cox survival models were built to examine the effect of TNF-α antagonists on the risk of a composite endpoint of cardiovascular outcomes defined as the occurrence of atherosclerotic heart disease, congestive heart failure, peripheral artery disease, or cerebrovascular disease, and on the risk of death. Treatment with TNF-α antagonists was not associated with a significant effect on the composite endpoint of cardiovascular outcomes. When each outcome was examined separately, the use TNF-α antagonists was not associated with an increased risk of atherosclerotic heart disease, congestive heart failure, or peripheral artery disease, but it was associated with decreased risk of cerebrovascular disease (hazard ratio [HR] = 0.83; confidence interval [CI] = 0.70-0.98). The use of TNF-α antagonists did not affect the risk of death (HR = 0.99; CI = 0.87-1.14). In subgroup analyses, the use TNF-α antagonists was associated with a reduced risk of cardiovascular outcomes (HR = 0.90, CI = 0.83-0.98) in patients younger than the median age of our cohort (63 years). The use TNF-α antagonists was not associated with a change in the risk of death in any other subgroup. These results show that the risk of cardiovascular events and survival in patients who receive TNF-α antagonists is not different than those who receive other DMARDs.

Abstract
The effect of rate of decline of kidney function on risk for death is not well understood. Using the Department of Veterans Affairs national databases, we retrospectively studied a cohort of 4171 patients who had rheumatoid arthritis and early stage 3 chronic kidney disease (CKD; estimated GFR 45 to 60 ml/min) and followed them longitudinally to characterize predictors of disease progression and the effect of rate of kidney function decline on mortality. After a median of 2.6 years, 1604 (38%) maintained stable kidney function; 426 (10%), 1147 (28%), and 994 (24%) experienced mild, moderate, and severe progression of CKD, respectively (defined as estimated GFR decline of 0 to 1, 1 to 4, and >4 ml/min per yr). Peripheral artery disease predicted moderate progression of CKD progression. Black race, hypertension, diabetes, cardiovascular disease, and peripheral artery disease predicted severe progression of CKD. After a median of 5.7 years, patients with severe progression had a significantly increased risk for mortality (hazard ratio 1.54; 95% confidence interval 1.30 to 1.82) compared with those with mild progression; patients with moderate progression exhibited a similar trend (hazard ratio 1.10; 95% confidence interval 0.98 to 1.30). Our results demonstrate an independent and graded association between the rate of kidney function decline and mortality. Incorporating the rate of decline into the definition of CKD may transform a static definition into a dynamic one that more accurately describes the potential consequences of the disease for an individual.

Abstract
OBJECTIVE Our purpose was to develop a geographically localized, multi-institution strategy for improving enrolment in a trial of secondary stroke prevention. METHODS We invited 11 Connecticut hospitals to participate in a project named the Local Identification and Outreach Network (LION). Each hospital provided the names of patients with stroke or TIA, identified from electronic admission or discharge logs, to researchers at a central coordinating center. After obtaining permission from personal physicians, researchers contacted each patient to describe the study, screen for eligibility, and set up a home visit for consent. Researchers traveled throughout the state to enroll and follow participants. Outside the LION, investigators identified trial participants using conventional recruitment strategies. We compared recruitment success for the LION and other sites using data from January 1, 2005, through June 30, 2007. RESULTS The average monthly randomization rate from the LION was 4.0 participants, compared with 0.46 at 104 other Insulin Resistance Intervention after Stroke (IRIS) sites. The LION randomized on average 1.52/1,000 beds/month, compared with 0.76/1,000 beds/month at other IRIS sites (p = 0.03). The average cost to randomize and follow one participant was $8,697 for the LION, compared with $7,198 for other sites. CONCLUSION A geographically based network of institutions, served by a central coordinating center, randomized substantially more patients per month compared with sites outside of the network. The high enrollment rate was a result of surveillance at multiple institutions and greater productivity at each institution. Although the cost per patient was higher for the network, compared with nonnetwork sites, cost savings could result from more rapid completion of research.

Abstract
This study examined the nature of the relationship among lifetime major depression, smoking, and nicotine dependence. Subjects were 8,169 male twins from the Vietnam Era Twin Registry. Biometrical modeling demonstrated a genetic influence on daily smoking, nicotine dependence, and major depression, and a family environmental influence on daily smoking. Genetic factors influencing nicotine dependence also strongly influenced major depression. We also compared probands with a history of major depression (n = 398) from pairs discordant for major depression, their nondepressed cotwins (n = 364), and controls (n = 1,863) on a number of secondary smoking outcomes. Major depression was associated with current daily smoking and certain nicotine withdrawal symptoms. Individuals with a familial vulnerability for major depression, even without a personal history of major depression, were more likely to smoke despite a serious illness and to report nervousness, restlessness, difficulty concentrating, and depressed mood during past quit attempts. Among the 237 monozygotic pairs discordant for major depression, depressed probands were more likely to have a lifetime history of nicotine dependence than were cotwins. Findings extend Kendler and colleague's (1993) study of female twins by demonstrating in men that shared genetic factors predispose not only to major depression and daily smoking but also to major depression and nicotine dependence.

Abstract
OBJECTIVE Research has examined the association of folate-dependent gene polymorphisms with methotrexate (MTX) toxicity in racially homogenous patients with rheumatoid arthritis (RA). We examined the influence of MTX transporter gene polymorphisms on MTX toxicity in 2 racial groups of patients with RA. METHODS Using a retrospective cross-validation approach, the association of polymorphisms in 6 genes in the MTX cellular pathway with MTX toxicity was examined in training and validation cohorts. The genes analyzed were ATP-binding cassette transporter B1 (ABCB1), C1 (ABCC1), C2 (ABCC2), folylpolyglutamyl synthase (FPGS), methylenetetrahydrofolate reductase (MTHFR), and thymidylate synthase (TYMS). Both cohorts included Caucasian Americans and African Americans. Statistical analyses consisted of Fisher exact tests, multivariable logistic regression models, and survival analyses. RESULTS Four of 25 variants displayed significant associations with MTX toxicity in the training cohort. The intronic single-nucleotide polymorphism (SNP) ABCC2 IVS 23+56 T --> C was associated with alopecia in Caucasians (p = 0.035). ABCB1 1236 C --> T was associated with overall toxicity (p = 0.013); ABCC2 1249 G --> A with gastrointestinal toxicity (p = 0.009); and ABCC2 1058 G --> A with hepatotoxicity (p = 0.04) in African Americans. These 4 SNP and the MTHFR 677 C --> T variant were assessed in the validation cohort. Of these, only the MTHFR 677 C --> T SNP was associated with alopecia, and only in African Americans (p = 0.032). The ABCC2 IVS 23+56 T --> C genotype influenced toxicity-related time to discontinuation or dose decrease in the Caucasian validation cohort (p < 0.0001). CONCLUSION In addition to SNP in folate-dependent genes, MTX transporter gene SNP may be important markers of MTX toxicity in RA. Such pharmacogenetic associations are race-specific.

Abstract
VA has a rich tradition in supporting research in areas that span basic science to health system implementation. Its unique success is tied to the fact that researchers are focused on issues that arise from a unique population--our nation's veterans. Moreover, because VA is the largest integrated health system in the country and because the health system must manage an annual budget, there is a keen interest among VA health administrators to apply research that enhances quality and efficiency of care. Furthermore, because these findings overlap with the general population, VA Research & Development programs can be applicable on a much broader scale.

Abstract
UNLABELLED Treatment with interferon and ribavirin is effective in patients with chronic infection with hepatitis C virus (HCV). Previous data indicate that treatment rates are suboptimal. We sought to identify patient and provider-level predictors of treatment receipt in HCV by conducting a retrospective cohort study of 5701 HCV patients in a large regional Veteran's Administration (VA) healthcare network. We also determined the degree of variation in treatment rates attributable to patient, provider, and facility factors. Three thousand seven hundred forty-three patients (65%) were seen by a specialist and 894 (15.7%) received treatment. Treatment rates varied from 6% to 29% across the 5 facilities included in the analysis. Patients were less likely to receive treatment if they were older [RR, 0.55; 95% CI, 0.45, 0.67), single (RR, 0.77; 95%CI, 0.67, 0.88), had hepatic dysfunction (RR, 0.73; 95%CI, 0.66, 0.89), had normal alanine aminotransferase (ALT) (RR, 0.73; 95%CI, 0.59, 0.89), had HCV genotype 1 (RR, 0.78; 95%CI, 0.71, 0.86), were African American with genotype 1 (RR, 0.78; 95% CI, 0.71, 0.86), or were anemic (RR, 0.70; CI, 0.60, 0.89). In addition, patients evaluated by less experienced providers were 77% less likely to receive treatment than those evaluated by more experienced providers. The patient, provider, and facility factors explained 23%, 25%, and 7% of variation in treatment rates, respectively. CONCLUSION These data suggest that although patient characteristics are important predictors of treatment in HCV, a significant proportion of variation in treatment rates is explained by provider factors. These potentially modifiable provider-level factors may serve as high-yield targets for future quality improvement initiatives in HCV.

Abstract
There are various hypotheses regarding comorbidity between alcohol dependence (AD) and major depression (MD). We interviewed 3372 pairs of male twins assessing DSM-III-R MD and AD. Individuals with comorbid MD and AD exhibited greater severity of each disorder than individuals with only one. MD in one twin was associated with risk of MD alone and MD plus AD, but not AD alone in the cotwin. AD in one twin was associated with risk of AD alone and AD plus MD, but not MD alone in the cotwin. The best fitting biometrical comorbidity model was the reciprocal causation model in which AD can cause MD and vice versa. However, a model in which genetic and environmental influences on each disorder were correlated could not be definitively rejected. Our data are most consistent with a mechanism of reciprocal causation, whereby MD increases risk for AD and AD increases risk of MD.

Abstract
The relative potencies of cholecystokinin (CCK)-8 and CCK-33 for decreasing meal size depend on the route of administration. Inhibitory potencies are equal after intraperitoneal administration, but CCK-33 is significantly more potent after intraportal administration. This suggests that CCK-33 is a more effective stimulant of hepatic afferent vagal nerves than is CCK-8. To investigate this possibility, we administered both peptides intraperitoneally in rats with abdominal vagotomies that spared only the hepatic proper vagal nerves (H) and in rats with abdominal vagotomies that spared the common hepatic branch that contains the fibers of the hepatic proper and gastroduodenal nerves (HGD). The vagal afferent innervation in H and HGD rats was verified with a wheat germ agglutinin-horseradish tracer strategy. Intraperitoneal administration of CCK-33 decreased 30-min intake of 10% sucrose in H rats as much as in sham rats, but CCK-8 decreased intake significantly less in H rats than in sham rats. The larger inhibitory effect of CCK-33 than of CCK-8 in H rats is consistent with the hypothesis that CCK-33 is a more effective stimulant of the hepatic proper vagal afferent nerves than CCK-8. In contrast to the results in H rats, the inhibitory potencies of both peptides were significantly and equivalently reduced in HGD rats compared with sham rats. This suggests that there is an inhibitory interaction between the stimulation of the gastroduodenal and hepatic proper afferent fibers by CCK-33.

Abstract
Several studies suggest veterans have a higher prevalence of hepatitis C virus infection than nonveterans, possibly because of military exposures. The purpose of this study was to estimate the prevalence of anti-hepatitis C antibody and evaluate factors associated with infection among users of Department of Veterans Affairs medical centers. Using a two-staged cluster sample, 1288 of 3863 randomly selected veterans completed a survey and underwent home-based phlebotomy for serological testing. Administrative and clinical data were used to correct the prevalence estimate for nonparticipation. The prevalence of antihepatitis C antibody among serology participants was 4.0% (95% CI, 2.6%-5.5%). The estimated prevalence in the population of Veterans Affairs medical center users was 5.4% (95% CI, 3.3%-7.5%) after correction for sociodemographic and clinical differences between participants and nonparticipants. Significant predictors of seropositivity included demographic factors, period of military service (e.g., Vietnam era), prior diagnoses, health care use, and lifestyle factors. At least one traditional risk factor (transfusion or intravenous drug use) was reported by 30.2% of all subjects. Among those testing positive for hepatitis C antibody, 78% either had a transfusion or had used injection drugs. Adjusting for injection drug use and nonparticipation, seropositivity was associated with tattoos and incarceration. Military-related exposures were not found to be associated with infection in the adjusted analysis. In conclusion, the prevalence of hepatitis C in these subjects exceeds the estimate from the general US population by more than 2-fold, likely reflecting more exposure to traditional risk factors among these veterans.

Abstract
BACKGROUND Results of previous research examining long-term residual effects of marijuana use on cognition are conflicting. A major methodological limitation of prior studies is the inability to determine whether differences between users and non-users are due to differences in genetic vulnerability preceding drug use or due to the effects of the drug. METHOD Fifty-four monozygotic male twin pairs, discordant for regular marijuana use in which neither twin used any other illicit drug regularly, were recruited from the Vietnam Era Twin Registry. A minimum of 1 year had passed since the marijuana-using twins had last used the drug, and a mean of almost 20 years had passed since the last time marijuana had been used regularly. Twins were administered a comprehensive neuropsychological test battery to assess general intelligence, executive functioning, attention, memory and motor skills. Differences in performance between marijuana-using twins and their non-using co-twins were compared using a multivariate analysis of specific cognitive domains and univariate analyses of individual test scores. Dose response relationships were explored within the marijuana-using group. RESULTS Marijuana-using twins significantly differed from their non-using co-twins on the general intelligence domain; however, within that domain only the performance of the block design subtest of the Wechsler Adult Intelligence Scale--Revised reached a level of statistical significance. CONCLUSIONS Out of the numerous measures that were administered, only one significant difference was noted between marijuana-using twins and their non-using co-twins on cognitive functioning. The results indicate an absence of marked long-term residual effects of marijuana use on cognitive abilities.

Abstract
Methotrexate (MTX) is a commonly used disease-modifying antirheumatic drug in rheumatoid arthritis (RA). Polymorphisms occur in several genes encoding key enzymes in the folic acid pathway, which is influenced by MTX, but have not been evaluated in patients with RA. The effect of race on allele frequency has also not been evaluated. In this study, the allele frequencies of polymorphisms in six key enzymes in the MTX–folate pathway in patients with RA and healthy controls, including several common racial groups were studied. European– and African–American patients with RA and European and African healthy controls were genotyped for 22 genetic loci in six genes in the MTX cellular pathway. Differences in genotype distributions between the different racial groups were evaluated using χ2 tests. Allele frequencies were significantly different (p < 0.001) for eight single nucleotide polymorphisms between the European and African controls. The allele frequencies of two polymorphisms showed significant differences (p < 0.001) between the African– and European–American patients with RA. Thus, racial differences exist between the allele frequencies of several polymorphisms in enzymes in the MTX-folate pathway in patients with RA and healthy controls. Whether such differences contribute to a differential response to MTX in patients with RA deserves to be investigated.

Abstract
Methotrexate (MTX) remains the most commonly used disease modifying antirheumatic drug in rheumatoid arthritis (RA) because of its cost and experience in its use, despite the availability of new treatments such as leflunomide and the biological agents. However, a significant number of patients with RA either do not benefit from the drug or are unable to tolerate it. Pharmacogenetic approaches may help optimise treatment with MTX, and also other agents, in RA.

Abstract
To investigate the gastric negative-feedback control of eating during a meal, we implanted male rats with pyloric cuffs and gastric catheters and gave them access to sweet milk for 30 min after overnight deprivation. Ingested milk and infused milk or saline were confined to the stomach because the pyloric cuffs were closed in all tests. Rats received five consecutive tests with no gastric infusion or with infusions of 3, 6, or 12 ml of milk or saline during the first 6 min of the test meal. Only 12-ml infusions decreased intake significantly compared with no infusion. Because 12 ml of saline inhibited intake as much as 12 ml of milk, the decreased intake was due to volume or rate of infusion, not nutrient. Although infusions of 3 and 6 ml of milk did not decrease intake, they decreased the number of licks after the infusions significantly more than equal volumes of saline. Thus a large volume or rapid rate of gastric infusion decreases intake, and some other aspect of small milk infusions decreases the rate of licking.

Abstract
Many individuals with a history of pathological gambling (PG) also have a history of engaging in antisocial behaviors, and this has often been interpreted as a result of the former causing the latter. In a sample of 7,869 men in 4,497 twin pairs from the Vietnam Era Twin Registry, the authors examined (a) the association between PG and antisocial personality disorder (ASPD), (b) the extent to which PG might be differentially associated with childhood conduct disorder (CD) and adult antisocial behavior (AAB), and (c) the contribution of genetic and environmental factors to the association of PG with ASPD, CD, and AAB. PG was significantly associated with all 3 antisocial behavior disorders, and the association of PG with ASPD, CD, and AAB was predominantly explained by genetic factors. The results of this study suggest that the greater-than-chance co-occurrence of PG and antisocial behavior disorders is partially due to their sharing a common genetic vulnerability. The antisocial behavior observed among many individuals with PG probably cannot be interpreted as being simply a consequence of the PG.

Abstract
The role of genetic and environmental influences on the relationship between combat exposure, posttraumatic stress disorder (PTSD) symptoms, and alcohol use were examined in 4072 male-male twin pairs who served in the United States military during the Vietnam era (1965-1975). Results indicate that the relationship between combat and alcohol use and between PTSD symptom factors and alcohol use were both substantially influenced by genetic factors. Findings are most consistent with a shared vulnerability model for the etiology of the association between PTSD symptoms and alcohol use. Specific unique environmental factors were more important than genetic factors for PTSD symptoms, and both factors were equally important for alcohol use. Further support is also found for the role of the unique environment in PTSD symptoms.

Abstract
BACKGROUND In comparison with alcohol dependence (AD), relatively little is known about the causes of pathological gambling (PG). Given the high rate of comorbidity between PG and AD, knowledge about the causes of AD may be applied to understanding those of PG. METHODS Subjects were adult male twin pairs from the Vietnam Era Twin Registry. Lifetime histories of PG and AD were assessed by structured psychiatric telephone interview. The validity of a continuum of PG liability was tested to determine whether the causes of subclinical PG, or problem gambling, are quantitatively or qualitatively distinct from those of DSM-III-R PG disorder. Genetic model-fitting methods were used to quantify the extent to which the genetic and environmental risk for PG could be explained by the risk for AD. RESULTS Tests of the continuity model of PG were all consistent with the hypothesis that subclinical PG and DSM-III-R PG disorder have many, perhaps all, of the same risk factors and thus differ quantitatively rather than qualitatively. Depending on the PG definition, between 12% and 20% of the genetic variation and between 3% and 8% of the nonshared environmental variation in the risk for PG were accounted for by the risk for AD. CONCLUSIONS Subclinical PG, or problem gambling, may be a milder form of PG, rather than an etiologically distinct syndrome. Risk for AD accounts for a significant but modest proportion of the genetic and environmental risk for subclinical PG and DSM-III-R PG disorder.

Abstract
There have been long questions about the relationship of schizophrenia to other mental disorders. Lifetime DSM-III-R diagnoses of mood and anxiety disorders in twins with clinically diagnosed schizophrenia (n = 24) and their non-affected co-twins (n = 24) were compared with twins from pairs without schizophrenia (n = 3327) using a sample from the Vietnam Era Twin Registry. Schizophrenic probands had significantly elevated rates of all included disorders (bipolar disorder, major depression, dysthymia, generalized anxiety disorder, panic disorder, and PTSD) compared with controls (P<0.01). The odd ratios comparing co-twins of schizophrenic probands with controls was greater than three for every disorder, but did not attain statistical significance. A similar pattern was observed when analyses were restricted to only monozygotic twins (n = 12). Consistent with other studies, schizophrenics appeared to have higher rates of a range of mental disorders. Our results suggest that schizophrenia per se represents a risk factor for other psychiatric disorders, but the absence of significantly elevated risk among non-schizophrenic co-twins suggested that family environmental and/or genetic factors that contribute to risk of schizophrenia do not increase the risk of mood and anxiety disorders to the same extent that the risk of these other disorders is increased by the presence of schizophrenia.

Abstract
Genetic and environmental factors influence drug abuse, but abuse represents the culmination of a sequence of events. Different levels of use may have different determinants and these determinants may differ across drug types. Approximately 3200 male-male twin pairs from the Vietnam Era Twin Registry were interviewed by telephone. Data were obtained regarding exposure to six categories of illicit drugs, initiation of use, continuation of use, regular usage, and diagnosis of drug abuse/dependence. Genetic, common environmental, and unique environmental influences on transitions of drug involvement, defined as movement from one level of drug use to the next, were investigated. Marijuana had the highest conditional probability for the transition from exposure to use, from use to use more than five times, and from use more than five times to regular use. The rate of transition to regular use of heroin was higher than the rate for amphetamine, cocaine, sedatives, and psychedelics. Cocaine had the highest conditional probability for the transition from regular use to abuse/dependence. Significant genetic influences were observed for a number of transitions in marijuana, amphetamine, and cocaine usage.
