RESUMO

BACKGROUND: Depression can impair the immunogenicity of vaccine administration in adults. Whereas many vaccinations are administered in childhood, it is not known whether adolescent or adult onset depression is associated with impairments in the maintenance of protection of childhood vaccines. This study tested the hypothesis that individuals with adolescent or adult onset mood disorders would display compromised immunity to measles, a target of childhood vaccination. METHODS: IgG antibodies to measles were quantified using a solid phase immunoassay in volunteers with bipolar disorder (BD, n = 64, mean age of onset = 16.6 ± 5.6), currently depressed individuals with major depressive disorder (cMDD, n = 85, mean age of onset = 17.9 ± 7.0), remitted individuals with a history of MDD (rMDD, n = 82, mean age of onset = 19.2 ± 8.6), and non-depressed comparison controls (HC, n = 202), all born after the introduction of the measles vaccine in the USA in 1963. RESULTS: Relative to HC, both the cMDD group (p = 0.021, adjusted odds ratios (OR) = 0.47, confidence interval (CI) = 0.24-0.90), and the rMDD group (p = 0.038, adjusted OR = 0.50, CI = 0.26-0.97) were less likely to test seropositive for measles. Compared with unmedicated MDD participants, currently medicated MDD participants had a longer lifetime duration of illness and were less likely to test seropositive for measles. CONCLUSIONS: Individuals with adolescent or adult onset MDD are less likely to test seropositive for measles. Because lower IgG titers are associated with increased risk of measles infection, MDD may increase the risk and severity of infection possibly because of impaired maintenance of vaccine-related protection from measles.

RESUMO

PURPOSE/BACKGROUND: Prolactin-related adverse effects contribute to nonadherence and adverse health consequences, particularly in women with severe mental illness. Treating these adverse effects may improve treatment acceptability, adherence, and long-term outcomes. METHODS/PROCEDURES: Premenopausal women with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder were recruited for a randomized, double-blind, placebo-controlled 16-week trial of adjunct aripiprazole (5-15 mg/d). Participants had elevated prolactin (>24 ng/mL) and were experiencing galactorrhea, amenorrhea, oligomenorrhea, or sexual dysfunction on a prolactin-elevating antipsychotic. Participants were evaluated biweekly for prolactin elevation and galactorrhea and completed a menstrual diary review. Psychiatric symptoms and adverse effects were closely monitored. FINDINGS/RESULTS: Forty-six women were randomized (n = 25 aripiprazole, n = 21 placebo). Thirty-seven completed at least 8 weeks of the study (n = 20 [80%] aripiprazole and n = 17 [81%] placebo). Aripiprazole (mean dose, 11.7 ± 2.4 mg/d) was effective for lowering prolactin relative to placebo (P = 0.04). In addition, 45% (9/20) of the aripiprazole group had a normalized prolactin (<24 mg/mL) compared with 12% (2/17) of the placebo group (P = 0.028). Galactorrhea resolved in 77% (10/13) of the aripiprazole-treated participants compared with 33% (4/12) in the placebo group (P = 0.028). Normalization of sexual function (<16 on the Arizona Sexual Experience Scale) occurred in 50% on aripiprazole (7/14) versus 9% (1/11) on placebo (P = 0.030). No differences between groups in symptoms or adverse effects were noted. Overall, women rated a mean score of 4.6 ± 0.6 on a 5-point Likert scale for sexual function improvement, suggesting their particular satisfaction with improvement in this domain. IMPLICATIONS/CONCLUSIONS: Building upon prior studies, this rigorous evaluation confirms the utility of adjunctive aripiprazole as a strategy for improving prolactin and managing prolactin-related adverse effects in premenopausal women with psychosis.

RESUMO

The molecules and pathways of the gut-brain axis represent new targets for developing methods to diagnose and treat psychiatric disorders. Manipulation of the gut microbiome with probiotics may be a therapeutic strategy with the potential to relieve gastrointestinal (GI) comorbidities and improve psychiatric symptoms. Candida albicans and Saccharomyces cerevisiae, commensal yeast species, can be imbalanced in the unhealthy human microbiome, and these fungal exposures were previously found elevated in schizophrenia. In a longitudinal, double-blind, placebo-controlled, pilot investigation of 56 outpatients with schizophrenia, we examined the impact of probiotic treatment on yeast antibody levels, and the relationship between treatment and antibody levels on bowel discomfort and psychiatric symptoms. We found that probiotic treatment significantly reduced C. albicans antibodies over the 14-week study period in males, but not in females. Antibody levels of S. cerevisiae were not altered in either treatment group. The highest levels of bowel discomfort over time occurred in C. albicans-seropositive males receiving the placebo. We observed trends towards improvement in positive psychiatric symptoms in males treated with probiotics who were seronegative for C. albicans. Results from this pilot study hint at an association of C. albicans seropositivity with worse positive psychiatric symptoms, which was confirmed in a larger cohort of 384 males with schizophrenia. In conclusion, the administration of probiotics may help normalize C. albicans antibody levels and C. albicans-associated gut discomfort in many male individuals. Studies with larger sample sizes are warranted to address the role of probiotics in correcting C. albicans-associated psychiatric symptoms.

RESUMO

BACKGROUND: Overweight and obesity are epidemic among persons with serious mental illness, yet weight-loss trials systematically exclude this vulnerable population. Lifestyle interventions require adaptation in this group because psychiatric symptoms and cognitive impairment are highly prevalent. Our objective was to determine the effectiveness of an 18-month tailored behavioral weight-loss intervention in adults with serious mental illness. METHODS: We recruited overweight or obese adults from 10 community psychiatric rehabilitation outpatient programs and randomly assigned them to an intervention or a control group. Participants in the intervention group received tailored group and individual weight-management sessions and group exercise sessions. Weight change was assessed at 6, 12, and 18 months. RESULTS: Of 291 participants who underwent randomization, 58.1% had schizophrenia or a schizoaffective disorder, 22.0% had bipolar disorder, and 12.0% had major depression. At baseline, the mean body-mass index (the weight in kilograms divided by the square of the height in meters) was 36.3, and the mean weight was 102.7 kg (225.9 lb). Data on weight at 18 months were obtained from 279 participants. Weight loss in the intervention group increased progressively over the 18-month study period and differed significantly from the control group at each follow-up visit. At 18 months, the mean between-group difference in weight (change in intervention group minus change in control group) was -3.2 kg (-7.0 lb, P=0.002); 37.8% of the participants in the intervention group lost 5% or more of their initial weight, as compared with 22.7% of those in the control group (P=0.009). There were no significant between-group differences in adverse events. CONCLUSIONS: A behavioral weight-loss intervention significantly reduced weight over a period of 18 months in overweight and obese adults with serious mental illness. Given the epidemic of obesity and weight-related disease among persons with serious mental illness, our findings support implementation of targeted behavioral weight-loss interventions in this high-risk population.

RESUMO

OBJECTIVE: Consumers with serious mental illness smoke more and are at higher risk for smoking-related illness. We examined provider and consumer factors influencing the implementation of the evidence-based "5 A's" (ask, advise, assess, assist, arrange) in six community mental health centers in greater Baltimore. METHODS: Data collected as part of a larger study examining the effectiveness of delivery of the 5 A's at patient visits. First, we examined responses to a survey administered to 49 clinicians on barriers and attitudes toward delivering the 5 A's. Second, we used multilevel models to examine variance between patients (n = 228), patient factors, and variance between their psychiatrists (n = 28) in the delivery of the 5 A's (and first 3 A's). RESULTS: The most strongly endorsed barrier was perceived lack of patient interest in smoking cessation. Psychiatrists and patients both accounted for significant variance in the delivery of the 5 A's and 3 A's. Patient "readiness to change" predicted delivery of the full 5 A's, while smoking severity predicted delivery of the first 3 A's. CONCLUSIONS: There is a critical need for creative and collaborative solutions, policies, and clinician training to address actual and perceived obstacles to the delivery of evidence-based smoking cessation treatment in the mental health care setting.

RESUMO

OBJECTIVES: Immune sensitivity to wheat glutens and bovine milk caseins may affect a subset of individuals with bipolar disorder. Digested byproducts of these foods are exorphins that have the potential to impact brain physiology through action at opioid receptors. Inflammation in the gastrointestinal (GI) tract might accelerate exposure of food antigens to systemic circulation and help explain elevated gluten and casein antibody levels in individuals with bipolar disorder. METHODS: We measured a marker of GI inflammation, anti-Saccharomyces cerevisiae antibodies (ASCA), in non-psychiatric controls (n = 207), in patients with bipolar disorder without a recent onset of psychosis (n = 226), and in patients with bipolar disorder with a recent onset of psychosis (n = 38). We compared ASCA levels to antibodies against gluten, casein, Epstein-Barr virus (EBV), herpes simplex virus 1 (HSV-1), influenza A, influenza B, measles, and Toxoplasma gondii. RESULTS: Elevated ASCA conferred a 3.5-4.4-fold increased odds ratio of disease association (age-, race-, and gender-corrected multinomial logistic regressions, p ≤ 0.00001) that was independent of type of medication received. ASCA correlated with food antibodies in both bipolar disorder groups (R(2)  = 0.29-0.59, p ≤ 0.0005), and with measles and T. gondii immunoglobulin G (IgG) in the recent onset psychosis bipolar disorder group (R(2)  = 0.31-0.36, p ≤ 0.004-0.01). CONCLUSIONS: Elevated seropositivity of a GI-related marker and its association with antibodies to food-derived proteins and self-reported GI symptoms suggest a GI comorbidity in at least a subgroup of individuals with bipolar disorder. Marker seroreactivity may also represent part of an overall heightened activated immune state inherent to this mood disorder.

RESUMO

OBJECTIVES: Bipolar disorder (BD) is frequently misdiagnosed as major depressive disorder (MDD), which may lead to inappropriate treatment and poor outcomes. This study aimed to compare demographic and clinical features between patients with MDD and those with BD, but being misdiagnosed as MDD, in China. METHODS: A total of 1487 patients diagnosed with MDD were consecutively evaluated in 13 psychiatric hospitals or psychiatric units of general hospitals nationwide in China. The patients' sociodemographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. The Mini-International Neuropsychiatric Interview (MINI) was used to establish DSM-IV diagnoses, and identify patients with MDD and those with BD, but being misdiagnosed with MDD. RESULTS: The proportions of BD (all types), bipolar I disorder (BD-I), and bipolar II disorder (BD-II) misdiagnosed as MDD in clinical practice were 20.8%, 7.9%, and 12.8%, respectively. Multiple logistic regression analyses revealed that compared to MDD patients, BD-I was characterized by more atypical depressive features (increased appetite, increased sleep, and weight gain) [odds ratio (OR) = 2.0, 95% confidence interval (CI): 1.2-3.2], more psychotic symptoms (OR = 2.1, 95% CI: 1.3-3.5), more lifetime depressive episodes (OR = 1.1, 95% CI: 1.1-1.2), and earlier age of onset (OR = 0.97, 95% CI: 0.9-0.99); BD-II was characterized by more psychotic symptoms (OR = 2.1, 95% CI: 1.4-3.1) and earlier age of onset (OR = 0.96, 95% CI: 0.9-0.97). In addition, compared to BD-II patients, BD-I patients were characterized by more frequent depressive episodes per year (OR = 3.1, 95% CI: 1.5-6.6). CONCLUSIONS: Depressive episodes in the context of BD-I and BD-II, among those who were misclassified as MDD, present some different clinical features compared to MDD. This finding should be taken into account in guiding diagnostic practices in China.

RESUMO

Prolactin elevations occur in people treated with antipsychotic medications and are often much higher in women than in men. Hyperprolactinemia is known to cause amenorrhea, oligomenorrhea, galactorrhea and gynecomastia in females and is also associated with sexual dysfunction and bone loss. These side effects increase risk of antipsychotic nonadherence and suicide and pose significant problems in the long term management of women with schizophrenia. In this manuscript, we review the literature on prolactin; its physiology, plasma levels, side effects and strategies for treatment. We also present the rationale and protocol for an ongoing clinical trial to treat symptomatic hyperprolactinemia in premenopausal women with schizophrenia. More attention and focus are needed to address these significant side effects and help the field better personalize the treatment of women with schizophrenia.

RESUMO

Objective: Cigarette smoking is the most preventable cause of disease and death in the US. We examined the prevalence of smoking and the association between smoking status and health characteristics in persons with serious mental illness. Methods: A total of 291 overweight or obese adults with serious mental illness were enrolled in a behavioral weight loss trial. Cigarette smoking, co-occurring medical diagnoses, dietary intake, blood pressure, cardiovascular fitness, body mass index, quality of life, and psychiatric symptoms were assessed at baseline in 2008-2011. Fasting glucose and lipid markers were measured from blood samples. Cardiovascular risk profile was calculated based on the global Framingham Health Study Risk Equation. Results: A total of 128 (44%) of participants were current smokers or had smoked in the previous one year. The smokers had significantly higher diastolic blood pressure and blood triglyceride levels, and lower HDL cholesterol than the nonsmokers, adjusted for age, sex, education, and diagnosis. They were more likely to have a history of emphysema, and had a 10-year cardiovascular disease risk of 13.2%, significantly higher than the 7.4% in the nonsmokers. The smokers also had elevated ratings of psychopathology on the BASIS-24 scale. Smokers did not differ from nonsmokers in cardiovascular fitness, body mass index, depression, quality of life, or other comorbid medical diagnoses. There was no characteristic in which smokers appeared healthier than nonsmokers. Conclusions: The prevalence of smoking in this contemporary cohort of individuals with serious mental illness who were motivated to lose weight was more than twice that in the overall population. Smokers had more indicators of cardiovascular disease and poorer mental health than did nonsmokers. The high burden of comorbidity in smokers with serious mental illness indicates a need for broad health interventions.

RESUMO

BACKGROUND: The pandemic caused by severe acute respiratory syndrome-Coronavirus-2 (SARS-CoV-2) has highlighted the importance of coronaviruses in human health. Several seasonal, non-SARS Coronaviruses are endemic in most areas of the world. In a previous study, we found that the level of antibodies to these seasonal Coronaviruses was elevated in persons with a recent onset of psychosis. In the current study, the level of antibodies to seasonal Coronaviruses was compared between individuals with psychiatric disorders and a non-psychiatric comparison group. METHODS: Participants (N = 195) were persons with a diagnosis of schizophrenia, bipolar disorder, major depressive disorder, or without a psychiatric disorder. Each participant had a blood sample drawn from which were measured IgG antibodies to the spike proteins in four non-SARS Coronaviruses, 229E, HKU1, NL63, and OC43, using a multiplex electrochemiluminescence assay. Linear regression models were employed to compare the levels of antibodies between each psychiatric group and the comparison group adjusting for demographic variables. Logistic regression models were employed to calculate the odds ratios associated with increased levels of antibodies to each seasonal Coronavirus based on the 50th percentile level of the comparison group. RESULTS: The schizophrenia group had significantly increased levels of antibodies to the seasonal Coronaviruses OC43 and NL63. This group also had increased odds of having elevated antibody levels to OC43. The major depression group showed a significantly lower level of antibodies to Coronavirus 229E. There were no significant differences between any of the psychiatric groups and the comparison group in the levels of antibodies to seasonal Coronaviruses 229E or HKU1. CONCLUSIONS: The elevated level of antibodies to OC43 and NL63 in the schizophrenia group indicates increased exposure to these agents and raises the possibility that Coronaviruses may contribute to the etiopathology of this disorder. The cause-and-effect relationship between seasonal Coronaviruses and psychiatric disorders should be the subject of additional investigations focusing on longitudinal cohort studies.

RESUMO

Importance: Tobacco smoking drives markedly elevated cardiovascular disease risk and preventable death in persons with serious mental illness, and these risks are compounded by the high prevalence of overweight/obesity that smoking cessation can exacerbate. Guideline-concordant combined pharmacotherapy and behavioral smoking cessation treatment improves abstinence but is not routinely offered in community settings, particularly to those not seeking to quit smoking immediately. Objective: To determine the effectiveness of an 18-month pharmacotherapy and behavioral smoking cessation intervention incorporating weight management and support for physical activity in adults with serious mental illness interested in quitting smoking within 1 or 6 months. Design, Setting, and Participants: This was a randomized clinical trial conducted from July 25, 2016, to March 20, 2020, at 4 community health programs. Adults with serious mental illness who smoked tobacco daily were included in the study. Participants were randomly assigned to intervention or control, stratified by willingness to try to quit immediately (within 1 month) or within 6 months. Assessors were masked to group assignment. Interventions: Pharmacotherapy, primarily varenicline, dual-form nicotine replacement, or their combination; tailored individual and group counseling for motivational enhancement; smoking cessation and relapse prevention; weight management counseling; and support for physical activity. Controls received quitline referrals. Main Outcome and Measures: The primary outcome was biochemically validated, 7-day point-prevalence tobacco abstinence at 18 months. Results: Of the 298 individuals screened for study inclusion, 192 enrolled (mean [SD] age, 49.6 [11.7] years; 97 women [50.5%]) and were randomly assigned to intervention (97 [50.5%]) or control (95 [49.5%]) groups. Participants self-identified with the following race and ethnicity categories: 93 Black or African American (48.4%), 6 Hispanic or Latino (3.1%), 90 White (46.9%), and 9 other (4.7%). A total of 82 participants (42.7%) had a schizophrenia spectrum disorder, 62 (32.3%) had bipolar disorder, and 48 (25.0%) had major depressive disorder; 119 participants (62%) reported interest in quitting immediately (within 1 month). Primary outcome data were collected in 183 participants (95.3%). At 18 months, 26.4% of participants (observed count, 27 of 97 [27.8%]) in the intervention group and 5.7% of participants (observed count, 6 of 95 [6.3%]) in the control group achieved abstinence (adjusted odds ratio [OR], 5.9; 95% CI, 2.3-15.4; P < .001). Readiness to quit within 1 month did not statistically significantly modify the intervention's effect on abstinence. The intervention group did not have significantly greater weight gain than the control group (mean weight change difference, 1.6 kg; 95% CI, -1.5 to 4.7 kg). Conclusions and Relevance: Findings of this randomized clinical trial showed that in persons with serious mental illness who are interested in quitting smoking within 6 months, an 18-month intervention with first-line pharmacotherapy and tailored behavioral support for smoking cessation and weight management increased tobacco abstinence without significant weight gain.

RESUMO

Immune system factors including complement pathway activation are increasingly linked to the etiology and pathophysiology of schizophrenia. Complement protein, C1q, binds to and helps to clear immune complexes composed of immunoglobulins coupled to antigens. The antigenic stimuli for C1q activation in schizophrenia are not known. Food sensitivities characterized by elevated IgG antibodies to bovine milk caseins and wheat glutens have been reported in individuals with schizophrenia. Here, we examined the extent to which these food products might comprise the antigen component of complement C1q immune complexes in individuals with recent onset schizophrenia (n=38), non-recent onset schizophrenia (n=61) and non-psychiatric controls (n=63). C1q seropositivity was significantly associated with both schizophrenia groups (recent onset, odds ratio (OR)=8.02, p≤0.008; non-recent onset, OR=3.15, p≤0.03) compared to controls (logistic regression models corrected for age, sex, race and smoking status). Casein- and/or gluten-IgG binding to C1q was significantly elevated in the non-recent onset group compared to controls (OR=4.36, p≤0.01). Significant amounts of C1q-casein/gluten-related immune complexes and C1q correlations with a marker for gastrointestinal inflammation in non-recent onset schizophrenia suggests a heightened rate of food antigens in the systemic circulation, perhaps via a disease-associated altered intestinal permeability. In individuals who are in the early stages of disease onset, C1q activation may reflect the formation of immune complexes with non-casein- or non-gluten-related antigens, the presence of C1q autoantibodies, and/or a dissociated state of immune complex components. In conclusion, complement activation may be a useful biomarker to diagnose schizophrenia early during the course of the disease. Future prospective studies should evaluate the impacts of casein- and gluten-free diets on C1q activation in schizophrenia.

RESUMO

OBJECTIVE: This study surveyed the prescribing patterns of antipsychotic medications in Asian older schizophrenia patients with extrapyramidal side effects (EPS) during the period between 2001 and 2009. METHOD: Information on 848 hospitalized patients with schizophrenia aged 60 or older was extracted from the database of the Research on Asian Psychotropic Prescription Patterns (REAP) study (2001 - 2009). Data from those patients with reported EPS from 8 Asian countries and territories including China, Hong Kong, Japan, Korea, Singapore, Taiwan, India and Malaysia were analyzed. The cross-sectional data of sociodemographic and clinical characteristics and antipsychotic prescriptions were collected using a standardized protocol and data collection procedure. RESULTS: Of the 309/848 (36%) patients suffering from EPS, 210 patients (210/309; 68.0%) received at least one type of first generation antipsychotic (FGA), and 99 (99/309; 32.0%) received second generation antipsychotics (SGAs) only. Of SGAs prescribed in patients with EPS, risperidone was the most commonly used (100/309; 32.4%) followed by olanzapine (33/309; 10.7%) and quetiapine (25/309; 8.1%). CONCLUSIONS: FGAs were frequently used in Asian older schizophrenia patients with EPS. Considering the potential adverse effects of FGAs on existing EPS, the reasons for the frequent use of FGAs need to be urgently identified.

RESUMO

OBJECTIVE: This study examined the prescribing patterns of several first- (FGAs) and second-generation antipsychotic (SGAs) medications administered to older Asian patients with schizophrenia during the period between 2001 and 2009. METHOD: Information on hospitalized patients with schizophrenia aged 65 or older was extracted from the database of the Research on Asian Psychotropic Prescription Patterns (REAP) study (2001-2009). There were no older patients in Thailand, therefore data on 467 patients in eight Asian countries and territories including China, Hong Kong SAR, India, Japan, Korea, Malaysia, Singapore, and Taiwan were analysed. Cross-sectional socio-demographic data, clinical characteristics and antipsychotic prescriptions were assessed using a standardized protocol and data collection procedure. RESULTS: Of the 467 patients, 192 patients (41.1%) received FGAs only, 166 (35.5%) received SGAs only and 109 (23.3%) received a combination of FGAs and SGAs. Of the FGAs, haloperidol was the most commonly used (31.3%; mean 9.4 ± 6.7 mg/day), followed by chlorpromazine (15.4%; mean 126.4 ± 156.4 mg/day) and sulpiride (6.6%; mean 375.0 ± 287.0 mg/day). Of the SGAs, risperidone was the most commonly used (31.5%; mean 4.5 ± 2.7 mg/day), followed by olanzapine (13.1%; mean 13.6 ± 6.5 mg/day), quetiapine (7.3%; mean 325.0 ± 237.3 mg/day) and aripiprazole (1.9%; mean 17.6 ± 7.7 mg/day). CONCLUSIONS: FGAs and higher doses of certain SGAs (risperidone, olanzapine and quetiapine) were still commonly dispensed to older Asian patients with schizophrenia. Considering older patients' reduced tolerability of potentially severe side effects associated with FGAs and higher doses of certain SGAs, continuing education and training addressing the rational use of antipsychotics in this population is clearly needed.

RESUMO

Youth with mental illness have higher levels of obesity than children in the general population. Both regular physical activity and limited screen time have been recommended to reduce and prevent childhood obesity. This study examines accelerometer-based moderate-vigorous physical activity (MVPA) and screen time among youth with overweight/obesity issues who are receiving mental health care. This study looked at a 12-month weight management randomized clinical trial for overweight/obese youth aged 8-18 years who are receiving mental health services. At baseline, MVPA was assessed using accelerometers, and screen time was self-reported. Among 100 youth, 43% were female, 44% were Black, and 48% were <13 years old. In an adjusted general linear model, higher levels of MVPA were associated with the younger age group (p = 0.012), male participants (p = 0.013), and lower BMI z-scores (p = 0.014). In a separate model, higher screen time was associated with participants who were Black (p = 0.007). Achieving optimal cardiovascular health at the population level requires an understanding of the groups that are most in need of additional assistance. These data reinforce that targeted lifestyle approaches to promote increased physical activity and decreased screen time among overweight/obese youth using mental health services may need additional tailoring for sex, age, and race subgroups.

RESUMO

Inadequate self-management of chronic medical conditions like Type 2 diabetes may play a role in the poor health status of individuals with serious mental illnesses. We compared adherence to hypoglycemic medications and blood glucose control between 44 diabetes patients with a serious mental illness and 30 patients without a psychiatric illness. The two groups did not differ in their ability to manage a complex medication regimen as assessed by a performance-based measure of medication management capacity. However, significantly fewer patients with a mental illness self-reported nonadherence to their hypoglycemic regimens compared to those without a mental illness. Although individuals with mental illnesses also had better control of blood glucose, this metabolic parameter was not correlated with adherence to hypoglycemic medications in either patient group. The experience of managing a chronic mental illness may confer advantages to individuals with serious mental illnesses in the self-care of co-occurring medical conditions like Type 2 diabetes.

RESUMO

Many patients with schizophrenia have psychological distress and receive some form of psychotherapy. Several different psychotherapeutic approaches for schizophrenia have been developed and studied. Of these approaches, cognitive behavior therapy (CBT) has the strongest evidence base and has shown benefit for symptom reduction in outpatients with residual symptoms. In addition to CBT, other approaches include compliance therapy, personal therapy, acceptance and commitment therapy, and supportive therapy. Although usually studied as distinct approaches, these therapies overlap with each other in their therapeutic elements. Psychotherapy for schizophrenia continues to evolve with the recent advent of such approaches as metacognitive therapy, narrative therapies, and mindfulness therapy. Future research may also consider three different goals of psychotherapy in this patient population: to provide emotional support, to enhance functional recovery, and to alter the underlying illness process.

RESUMO

Although studies suggest that patients with diabetes with a serious mental illness (SMI) have poor diabetes outcomes, reports conflict regarding the quality of their diabetes care and level of glucose control. In an observational follow-up to our initial cross-sectional study, we compared glucose control (glycosylated hemoglobin [HbA1c]) between patients with diabetes with SMI versus those without SMI at two postbaseline assessments during an approximately 5-year period. Both groups continued to have glucose levels higher than what is considered good control and neither group demonstrated a significant change in mean HbA1c at the two follow-up time points. Those with SMI continued to have lower HbA1c levels than those without SMI even after adjusting for potential confounders. More effective strategies are needed to assist patients with diabetes to improve the management of their glucose levels.

RESUMO

OBJECTIVE: Suboptimal diet may be related to the high prevalence of obesity and cardiovascular disease (CVD) in persons with serious mental illnesses, but few studies have characterized dietary intake in this population. METHODS: Participants were 102 overweight/obese adults with serious mental illnesses who were being screened for a weight loss trial in psychiatric rehabilitation centers. Direct observation of participant meals was completed using a standardized measurement form. RESULTS: CVD risk factors were common: mean body mass index was 35.7 kg/m2; 30% had diabetes. Participants consumed 100% of caloric beverages served (7.2 oz/meal) but consumption was significantly less than served for fruits (difference of 0.12 cups/meal, p=0.003) and vegetables (0.14 cups/meal, p=0.021). The majority (56%) of meat consumed was high fat. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Interventions designed to improve dietary intake of persons with serious mental illnesses are needed to improve health in this population at high risk for CVD.
