Functional health status of adults with serious mental illness and diabetes mellitus: A latent profile analysis.

OBJECTIVE: Adults with serious mental illness are at increased risk for diabetes mellitus and diabetes-related complications. This article classifies subgroups among people with serious mental illness and comorbid diabetes with respect to functional status and examines differences among those groups. METHODS: This analysis used a baseline sample of 157 adults with serious mental illness and diabetes mellitus enrolled in a National Institute of Health-funded research study. Latent profile analysis was used to distinguish health status profiles and investigate how these subgroups differed across assessment domains. RESULTS: Participants with depression, schizophrenia, and bipolar disorder (n = 157) were included in the study. Mean age was 52.9 years (standard deviation = 9.8), and 62 (40%) were African American. From the latent profile analysis, a three-class model appeared to provide the best fit. Class 1 (34.9%) had a very low functional health status approximately two standard deviations below the general population mean. Class 2 (43.7%) had a low functional status approximately one standard deviation below the general mean. Class 3 (21.4%) had moderate functional status with scores near population mean. Groups differed on measures of personal characteristics, clinical status and symptom severity, self-care behaviors, and environmental characteristics. CONCLUSIONS: Although individuals with schizophrenia generally have poor prognosis once they develop diabetes, latent profile analysis identified distinct health status subgroups. Although all three groups demonstrated illness burden, the pattern of differences between these groups across measures may suggest the need for different interventions for highly diverse adults who received care within safety-net primary care.

Angiotensin II Influences Pre-mRNA Splicing Regulation by Enhancing RBM20 Transcription Through Activation of the MAPK/ELK1 Signaling Pathway.

RNA binding motif 20 (RBM20) is a key regulator of pre-mRNA splicing of titin and other genes that are associated with cardiac diseases. Hormones, like insulin, triiodothyronine (T3), and angiotensin II (Ang II), can regulate gene-splicing through RBM20, but the detailed mechanism remains unclear. This study was aimed at investigating the signaling mechanism by which hormones regulate pre-mRNA splicing through RBM20. We first examined the role of RBM20 in Z-, I-, and M-band titin splicing at different ages in wild type (WT) and RBM20 knockout (KO) rats using RT-PCR; we found that RBM20 is the predominant regulator of I-band titin splicing at all ages. Then we treated rats with propylthiouracil (PTU), T3, streptozotocin (STZ), and Ang II and evaluated the impact of these hormones on the splicing of titin, LIM domain binding 3 (Ldb3), calcium/calmodulin-dependent protein kinase II gamma (Camk2g), and triadin (Trdn). We determined the activation of mitogen-activated protein kinase (MAPK) signaling in primary cardiomyocytes treated with insulin, T3, and Ang II using western blotting; MAPK signaling was activated and RBM20 expression increased after treatment. Two downstream transcriptional factors c-jun and ETS Transcription Factor (ELK1) can bind the promoter of RBM20. A dual-luciferase activity assay revealed that Ang II, but not insulin and T3, can trigger ELK1 and thus promote transcription of RBM20. This study revealed that Ang II can trigger ELK1 through activation of MAPK signaling by enhancing RBM20 expression which regulates pre-mRNA splicing. Our study provides a potential therapeutic target for the treatment of cardiac diseases in RBM20-mediated pre-mRNA splicing.

Associations among comorbid anxiety, psychiatric symptomatology, and diabetic control in a population with serious mental illness and diabetes: Findings from an interventional randomized controlled trial.

Objective Serious mental illness and type II diabetes mellitus have a high comorbidity, and both have a higher prevalence of anxiety disorders compared to the general population. Targeted Training in Illness Management is a group-based self-management training approach which targets serious mental illness and type II diabetes mellitus concurrently. This analysis examines data from a randomized controlled trial of Targeted Training in Illness Management intervention to examine the impact of comorbid anxiety on baseline psychiatric symptomatology and diabetic control, and on longitudinal treatment outcomes. Methods We conducted secondary analyses on data from a prospective, 60-week, randomized controlled trial testing Targeted Training in Illness Management versus treatment as usual in 200 individuals with serious mental illness and diabetes. Primary outcomes included measures related to serious mental illness symptoms, functional status, general health status, and diabetes control. Measures were compared between those participants with anxiety disorders versus those without anxiety at baseline as well as over time using linear mixed effects analyses. Results Forty seven percent of the participants had one or more anxiety disorders. At baseline, those with an anxiety diagnosis had higher illness severity, depressive, and other psychiatric symptomatology and disability. Diabetic control (HbA1c) was not significantly different at baseline. In the longitudinal analyses, no significant mean slope differences over time (group-by-time interaction effect) between those with anxiety diagnoses and those without in treatment as usual group were found for primary outcomes. Within the Targeted Training in Illness Management arm, those with anxiety disorders had significantly greater improvement in mental health functioning. Those with anxiety comorbidity in the Targeted Training in Illness Management group demonstrated significantly lower HbA1c levels compared to no anxiety comorbidity and also demonstrated a greater improvement in HbA1c over the first 30 weeks compared to those without anxiety comorbidity. Conclusion Comorbid anxiety in serious mental illness and type II diabetes mellitus population is associated with increased psychiatric symptomatology and greater disability. Individuals from this population appear to experience greater improvement in functioning from baseline with the Targeted Training in Illness Management intervention. Anxiety comorbidity in the serious mental illness and type II diabetes mellitus population does not appear to have a negative impact on diabetic control. These complex relationships need further study. Clinical Trials Registration ClinicalTrials.gov: Improving outcomes for individuals with serious mental illness and diabetes (NCT01410357).

A Preliminary Analysis of Individuals With Serious Mental Illness and Comorbid Diabetes.

OBJECTIVE: To understand factors related to managing illness in older individuals with serious mental illness (SMI). METHODS: Baseline data from 200 individuals with SMI and diabetes enrolled in a study were used to compare characteristics between older (age >55) vs. younger (age ≤55) individuals. RESULTS: Older individuals had better diabetes control compared to younger individuals, those with major depressive disorder had diabetes for a longer duration, worse diabetic control, and more emergency department encounters. CONCLUSIONS: Helping younger individuals with SMI learn to manage their mental and physical health early-on might minimize the negative and cumulative effect of diabetes.

Polynucleotide phosphorylase is required for Escherichia coli O157:H7 growth above refrigerated temperature.

BACKGROUND: The growth of Escherichia coli O157:H7 in contaminated dairy and other refrigerated food products due to temperature fluctuation poses a major food safety threat. Effective control or inhibition of E. coli O157:H7 growth depends on our understanding of mechanisms that regulate its growth at low temperature. We hypothesized that polynucleotide phosphorylase (PNPase) plays a critical role in E. coli O157:H7 low-temperature growth. METHODS: To test this hypothesis, the pnp deletion mutant of E. coli O157:H7 was generated using the λ Red recombinase system, and the growth and survival of wild-type and pnp deletion mutant strains were compared at low temperatures. RESULTS: The growth of pnp deletion mutant strains in Luria Broth (LB) and agar plate at 37°C was similar to their corresponding wild-type strains, while the deletion of pnp impaired E. coli O157:H7 growth in LB at 10°C and 22°C; growth impairment could be partially recovered in the mutant strains by ectopic expression of the pnp complementation plasmid, demonstrating that growth impairment was PNPase-specific. During 14 days of 10°C storage in both LB and milk, wild type strain EDL933 grew and reached >8 log10 colony-forming units per milliliter after 4 days of 10°C storage, while EDL933Δpnp gradually died off with effects more pronounced in milk, which were again mitigated by pnp overexpression. In addition, pnp deletion impaired the motility of E. coli O157:H7 but did not affect its susceptibility to H2O2. CONCLUSION: PNPase is required for the growth of E. coli O157:H7 at low temperature; PNPase thus provides a molecular target to control the growth of E. coli O157:H7, which may have important practical applications in dairy and other food industry.

Peer- and web-based interventions for risky drinking among US National Guard members: Mission Strong randomized controlled trial.

AIMS: To test separatel the efficacy of a web-based and a peer-based brief intervention (BI), compared with an expanded usual care control (EUC) group, among military reserve component members using alcohoI in a hazardous and harmful manner. DESIGN: In the randomized controlled trial, participants were assigned to: [1] web-based BI with web-based boosters (BI + web), [2] web-based BI with peer-based boosters (BI + peer) or [3] enhanced usual care (EUC). SETTING: Michigan, USA. PARTICIPANTS: A total of 739 Michigan Army National Guard members who reported recent hazardous alcohol use; 84% were male, the mean age was 28 years. INTERVENTION: The BI consisted of an interactive program guided by a personally selected avatar. Boosters were delivered either on the web or personally by a trained veteran peer. A pamphlet, given to all participants, included information on hazardous alcohol use and military-specific community resources and served as the EUC condition. MEASUREMENTS: The primary outcome measure was binge drinking episodes in the past 30 days, measured at 12 months after the BI. FINDINGS: All randomized participants were included in the outcome analyses. In adjusted analyses, BI + peer [beta = -0.43, 95% confidence interval (CI) = -0.56 to -0.31, P < 0.001] and BI + web (beta = -0.34, 95% CI = -0.46 to -0.23, P < 0.001) reduced binge drinking compared with EUC. CONCLUSION: This satudy was a web-based brief intervention for hazardous alcohol use, with either web- or peer-based boosters, reduced binge alcohol use among Army National Guard members.

Predictors of Booster Engagement Following a Web-Based Brief Intervention for Alcohol Misuse Among National Guard Members: Secondary Analysis of a Randomized Controlled Trial.

BACKGROUND: Alcohol misuse is a major health concern among military members. Reserve component members face unique barriers as they live off base with limited access to behavioral health services. Web and app-based brief interventions are a promising means to improve access to treatment for those who misuse alcohol, with the use of booster sessions to enhance effectiveness, solidify gains, and reinforce changes. However, little is known about who will engage in booster sessions. OBJECTIVE: This study aims to evaluate booster engagement across booster delivery modalities (Web and Peer) and identify participant-specific factors associated with booster session engagement. METHODS: Following a brief web-based alcohol misuse intervention in National Guard members (N=739), we examined engagement in a series of three booster sessions. Using unadjusted and adjusted models, demographic and clinical characteristics that may serve as predictors of booster session engagement were examined across the 2 arms of the trial with different types of booster sessions: peer-delivered (N=245) and web-delivered (N=246). RESULTS: Booster session completion was greater for Peer than Web Booster sessions, with 142 (58%) service members in the Peer Booster arm completing all three boosters compared with only 108 (44%) of participants in the Web Booster arm (χ23=10.3; P=.006). In a model in which the 2 groups were combined, socioeconomic factors predicted booster engagement. In separate models, the demographic and clinical predictors of booster engagement varied between the 2 delivery modalities. CONCLUSIONS: The use of peer-delivered boosters, especially among subsets of reserve members at risk of lack of engagement, may foster greater uptake and improve treatment outcomes.

Enhanced transforming growth factor-beta signaling and fibrogenesis in ovine fetal skeletal muscle of obese dams at late gestation.

Maternal obesity (MO) is increasing at an alarming rate. The objective of this study was to evaluate the effect of MO on fibrogenesis in fetal skeletal muscle during maturation in late gestation. Nonpregnant ewes were assigned to a control diet (Con; fed 100% of NRC nutrient recommendations, n = 6) or obesogenic diet (OB; fed 150% of NRC recommendations, n = 6) from 60 days before conception, and fetal semitendenosus (St) muscle was sampled at 135 days of gestation (term 148 days). Total concentration and area of collagen in cross-sections of muscle increased by 27.0 +/- 6.0 (P < 0.05) and 105.1 +/- 5.9% (P = 0.05) in OB compared with Con fetuses. The expression of precursor TGF-beta was 177.3 +/- 47.6% higher, and concentration of phospho-p38 74.7 +/- 23.6% was higher (P < 0.05) in OB than in CON fetal muscle. Increases of 327.9 +/- 168.0 (P < 0.05) and 188.9 +/- 82.1% (P < 0.05), respectively, were observed for mRNA expression of Smad7 and fibronectin in OB compared with Con muscles. In addition, enzymes involved in collagen synthesis, including lysyl oxidase, lysyl hydroxylase 2b, and prolyl 4-hydroxylase-alpha1, were increased by 350.2 +/- 90.0 (P < 0.05), 236.5 +/- 25.2 (P < 0.05), and 82.0 +/- 36.2% (P = 0.05), respectively, in OB muscle. In conclusion, MO-enhanced fibrogenesis in fetal muscle in late gestation was associated with upregulation of the TGF-beta/p38 signaling pathway. Enhanced fibrogenesis at such an early stage of development is expected to negatively affect the properties of offspring muscle because muscle fibrosis is a hallmark of aging.

Maternal obesity induces fibrosis in fetal myocardium of sheep.

Maternal obesity (MO) has harmful effects on both fetal development and subsequent offspring health. The impact of MO on fetal myocardium development has received little attention. Fibrogenesis is regulated by the transforming growth factor-ß (TGF-ß)/p38 signaling pathway. Using the well-established model of MO in pregnant sheep, we evaluated the effect of MO on TGF-ß/p38 and collagen accumulation in fetal myocardium. Nonpregnant ewes were assigned to a control diet [Con, fed 100% of National Research Council (NRC) nutrient recommendations] or obesogenic diet (OB, fed 150% of NRC recommendations) from 60 days before conception. Fetal ventricular muscle was sampled at 75 and 135 days of gestation (dG). At 75 dG, the expression of precursor TGF-ß was 39.9 ± 9.9% higher (P < 0.05) in OB than Con fetal myocardium, consistent with the higher content of phosphorylated Smad3 in OB myocardium. The phosphorylation of p38 tended to be higher in OB myocardium (P = 0.08). In addition, enhanced Smad complexes were bound to Smad-binding elements in 75 dG OB fetal myocardium measured by DNA mobility shift assay (130.2 ± 26.0% higher, P < 0.05). Similar elevation of TGF-ß signaling was observed in OB fetal myocardium at 135 dG. Total collagen concentration in OB was greater than Con fetal myocardium (2.42 ± 0.16 vs. 1.87 ± 0.04%, P < 0.05). Matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-3 were higher in the Con group compared with OB sheep (43.86 ± 16.01 and 37.23 ± 7.97% respectively, P < 0.05). In summary, MO results in greater fetal heart connective tissue accumulation associated with an upregulated TGF-ß/p38 signaling pathway at late gestation; such changes would be expected to negatively impact offspring heart function.

Prevalence and Severity of Alcohol and Cannabis Use Across the Urban-Rural Continuum in the Michigan National Guard.

PURPOSE: The National Guard provides critical support both domestically and abroad with soldiers dispersed throughout America and spanning the urban-rural continuum. To determine if location-specific interventions may be needed, we compared the prevalence and severity of cannabis and alcohol use among National Guard members across localities. METHODS: Michigan National Guard members were enrolled (N = 2,746) during drill weekends as part of a larger randomized behavioral trial. Cannabis (ASSIST; prevalence = 5%) and alcohol use (AUDIT; prevalence = 82%) were compared using hurdle regression models across locality status after adjusting for covariates. FINDINGS: Prevalence of cannabis and alcohol use was predicted by locality (adjusted odds ratio [AOR] = 0.913, 95% CI: 0.838-0.986, P = .029; AOR = 0.963, 95% CI: 0.929-0.998, P = .038, respectively), with more use in urban localities. Neither severity of cannabis nor alcohol use was predicted by locality status. CONCLUSIONS: Prevalence of cannabis and alcohol use in the National Guard is differentially elevated across localities with higher prevalence in more central, densely populated areas. Findings may inform future work considering accessibility and utilization of prevention and treatment services for Guard members across the urban-rural continuum.

Lay management of chronic disease: a qualitative study of living with hepatitis C infection.

OBJECTIVES: To examine management strategies and goals reported by people diagnosed with chronic hepatitis C. METHODS: We analyzed data from semistructured interviews (N = 42) and from electronic sources [illness narratives (N = 79) and Internet threaded discussions (N = 264)]. Line-by-line coding, comparisons, and team discussions generated catalogs of lay management strategies and goals. We analyzed code-based files to identify informants' selection of specific strategies for each goal. RESULTS: We classified lay management strategies into 3 categories: medical self-care, behavior change, and coping. These strategies were used selectively in addressing multiple goals, categorized as fighting the virus, strengthening the body, and managing consequences. CONCLUSIONS: Results underscore the diversity of strategies for living with a disease characterized by uncertain prognosis and variable expression of symptoms.

Communicating about alcohol consumption to nonharmful drinkers with Hepatitis C: patient and provider perspectives.

BACKGROUND: Abstaining from alcohol consumption is generally recommended for patients with Hepatitis C(HCV). However, mixed research findings coupled with a lack of consistent guidelines on alcohol consumption and HCV may influence what healthcare providers tell their HCV patients about drinking. This may be more problematic when advising nonharmful drinkers with HCV, a population for whom consumption would not bea problem in the absence of their HCV diagnosis. OBJECTIVE: This study explores what healthcare providers advise their HCV patients who are drinking alcohol at nonharmful levels about alcohol use and what these patients actually hear. DESIGN: We conducted separate focus groups and interviews about alcohol use and HCV with nonharmful drinkers with HCV (N=50) and healthcare providers (N=14) at a metropolitan teaching hospital. All focus groups and interviews were audio-taped, transcribed, and analyzed using NVivo, a qualitative data management and analysis program. RESULTS: We found similar themes about HCV and alcohol consumption (stop completely, occasional drink is ok, cut down, and provision of mixed/ambiguous messages), reported by both providers and patients.Patient respondents who reported hearing "stop completely"were more likely to have had their last medical visit at the gastroenterology (GI) clinic as opposed to the internal medicine (IM) clinic. Furthermore, IM providers were more likely to give their recommendations in"medical language" than were GI providers. CONCLUSIONS: To make the best health-related decisions about their disease, HCV patients need consistent information about alcohol consumption. Departments of Internal Medicine can increase provider knowledge about HCV and alcohol use by providing more education and training on HCV.

Race analysis in an African American sample with serious mental illness and comorbid diabetes.

OBJECTIVES: Targeted Training in Illness Management (TTIM) focuses on enhancing care engagement for people living with serious mental illness and diabetes. This secondary analysis from a 60-week, randomized controlled trial of TTIM versus treatment as usual evaluated racial subgroup outcomes. METHOD: Demographics, clinical characteristics, and diabetes status were evaluated for those self-identifying as non-Hispanic White, African American, and Hispanic. Longitudinal response to TTIM was evaluated using a multiple domain risk index. Due to their small sample size; those identifying as Hispanic were excluded from this analysis. RESULTS: Non-Hispanic White participants had greater baseline socioeconomic advantages. Baseline risk scores, glycosylated hemoglobin (HbA1c) values, and HbA1c differences over time were similar for African American and non-Hispanic White participants. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: African American participants living with serious mental illness and diabetes receiving TTIM did as well as non-Hispanic White participants. Inclusive approaches that feature peer support and are situated in safety-net health care settings need to be further investigated with respect to potentially impacting health disparities.

Aldosterone antagonism fails to attenuate age-associated left ventricular fibrosis.

Collagen accumulates disproportionately in cardiac remodeling induced by hypertension and associated with advancing age. Spironolactone (Spiro), an aldosterone antagonist, attenuates the accumulation of collagen induced by hypertension. It was hypothesized that Spiro would attenuate the age-associated increase in percent collagen in the heart. Female Fisher 344 rats at 3 months (Y), 12 months (M), and 21 months (O) of age were treated with Spiro (30 mg/kg/d) or vehicle (Veh) for 2 months, yielding six groups: Y-Veh, Y-Spiro, M-Veh, M-Spiro, O-Veh, and O-Spiro. Hearts were harvested for immunoblotting, RNA blotting, and biochemical analysis. Percent collagen in the left ventricle and septum was greatest in the oldest rats. Spiro did not significantly attenuate the age-associated increase in collagen fraction or the age-associated increases in expression of atrial natriuretic factor and beta-myosin heavy chain messenger RNA. Chronic aldosterone antagonism does not attenuate the age-associated increase in collagen fraction in the female Fisher 344 rat heart.

Maternal obesity in the ewe increases cardiac ventricular expression of glucocorticoid receptors, proinflammatory cytokines and fibrosis in adult male offspring.

Obesity during human pregnancy predisposes offspring to obesity and cardiovascular disease in postnatal life. In a sheep model of maternal overnutrition/obesity we have previously reported myocardial inflammation and fibrosis, as well as cardiac dysfunction in late term fetuses, in association with chronically elevated blood cortisol. Significant research has suggested a link between elevated glucocorticoid exposure in utero and hypertension and cardiovascular disease postnatally. Here we examined the effects of maternal obesity on myocardial inflammation and fibrosis of their adult offspring. Adult male offspring from control (CON) mothers fed 100% of National Research Council (NRC) recommendations (n = 6) and male offspring from obese mothers (MO) fed 150% NRC (n = 6), were put on a 12-week ad libitum feeding challenge then necropsied. At necropsy, plasma cortisol and left and right ventricular thickness were markedly increased (P<0.05) in adult male MO offspring. Myocardial collagen content and collagen-crosslinking were greater (P<0.05) in MO offspring compared to CON offspring in association with increased mRNA and protein expression of glucocorticoid receptors (GR). No group difference was found in myocardial mineralocorticoids receptor (MR) protein expression. Further, mRNA expression for the proinflammatory cytokines: cluster of differentiation (CD)-68, transforming growth factor (TGF)-ß1, and tumor necrosis factor (TNF)-α were increased (P < 0.05), and protein expression of CD-68, TGF-ß1, and TNF-α tended to increase (P<0.10) in MO vs. CON offspring. These data provide evidence for MO-induced programming of elevated plasma cortisol and myocardial inflammation and fibrosis in adult offspring potentially through increased GR.

Psychosocial Features of Clinically Relevant Patient Subgroups With Serious Mental Illness and Comorbid Diabetes.

OBJECTIVE: Care for people with serious mental illness and diabetes is complicated by clinical heterogeneity. This cross-sectional analysis of 200 individuals with comorbid serious mental illness and diabetes explored differentiation between patient subgroups that were characterized on the basis of selected dimensions within a biopsychosocial framework. METHODS: Relationships between self-efficacy, treatment expectation, social support, and depression were first assessed via bivariate Spearman correlations among 200 individuals participating in a randomized controlled trial who had diabetes along with major depression, bipolar disorder, or schizophrenia. Next, latent profile analyses were conducted to determine underlying subgroups on the basis of these variables. The resultant groups were compared on diabetes control, function, and symptoms. RESULTS: Two subgroups emerged. One had more severe psychiatric symptoms, low scores on other psychosocial variables, and worse diabetes control. The other had low levels of psychiatric symptoms, better scores on other variables, and better diabetes control. CONCLUSIONS: Symptom presentation and internal and external resources appeared to be related to diabetes control for people with comorbid diabetes and serious mental illness. Care approaches need to go beyond standard education and consider biopsychosocial variables.

Clinic Appointment Attendance in Adults with Serious Mental Illness and Diabetes.

OBJECTIVES: We assessed characteristics that may predict outpatient appointment attendance in outpatient medical clinics among patients comorbid for serious mental illness (SMI) and type 2 diabetes (DM). METHODS: Baseline covariate data from 200 individuals with SMI-DM enrolled in a randomized controlled trial (RCT) were used to examine characteristics associated with electronic health record-identified clinic appointment attendance using a generalized estimating equations approach. The analyses evaluated the relationship between clinic attendance and potentially modifiable factors including disease knowledge, self-efficacy, social support, physical health, and mental health, as well as demographic information. RESULTS: Demographic and mental health characteristics were most associated with clinic attendance in adults with SMI-DM. Physical health was not associated with clinic attendance. CONCLUSIONS: Information on clinical and demographic characteristics and factors potentially modifiable by psychological interventions may be useful in improving adherence to treatment among SMI-DM patients. It is our hope that clinicians and researchers will use these results to help tailor adherence-facilitating interventions among people at particular risk for poor engagement in care.

A 60-Week Prospective RCT of a Self-Management Intervention for Individuals With Serious Mental Illness and Diabetes Mellitus.

OBJECTIVES: A 60-week randomized controlled trial assessed the effects of targeted training in illness management (TTIM) versus treatment as usual among 200 individuals with serious mental illness and diabetes mellitus. METHODS: The study used the Clinical Global Impression (CGI), the Montgomery-Asberg Depression Rating Scale (MADRS), and the Brief Psychiatric Rating Scale (BPRS) to assess psychiatric symptoms; the Global Assessment of Functioning (GAF) and the Sheehan Disability Scale (SDS) to assess functioning; the 36-Item Short-Form Health Survey (SF-36) to assess general health, and serum glycosylated hemoglobin (HbA1c) to assess diabetes control. RESULTS: Participants' mean±SD age was 52.7±9.5 years, and 54% were African American. They were diagnosed as having depression (48%), schizophrenia (25%), and bipolar disorder (28%). At baseline, depression severity was substantial but psychosis severity was modest. At 60 weeks, there was greater improvement among TTIM participants versus treatment-as-usual recipients on the CGI (p<.001), the MADRS (p=.016), and the GAF (p=.003). Diabetes knowledge was significantly improved among TTIM participants but not in the treatment-as-usual group. In post hoc analyses among participants whose HbA1c levels at baseline met recommendations set by the American Diabetes Association for persons with high comorbidity (53%), TTIM participants had minimal change in HbA1c over the 60-week follow-up, whereas HbA1c levels worsened in the treatment-as-usual group. CONCLUSIONS: TTIM was associated with improved psychiatric symptoms, functioning, and diabetes knowledge compared with treatment as usual. Among participants with better diabetes control at baseline, TTIM participants had better diabetes control at 60 weeks compared with recipients of treatment as usual.
