RESUMO

Little is known about central nervous system (CNS) responses to emotional stimuli in asthma. Nitric oxide in exhaled breath (FENO) is elevated in asthma due to allergic immune processes, but endogenous nitric oxide is also known to modulate CNS activity. We measured fMRI blood oxygen-dependent (BOLD) brain activation to negative (blood-injection-injury themes) and neutral films in 31 participants (15 with asthma). Regions-of-interest analysis was performed on key areas relevant to central adaptive control, threat processing, or salience networks, with dorsolateral prefrontal cortex (PFC), anterior insula, dorsal anterior cingulate cortex (dACC), amygdala, ventral striatum, ventral tegmentum, and periaqueductal gray, as well as top-down modulation of emotion, with ventrolateral and ventromedial PFC. Both groups showed less BOLD deactivation from fixation cross-baseline in the left anterior insula and bilateral ventromedial PFC for negative than neutral films, and for an additional number of areas, including the fusiform gyrus, for film versus recovery phases. Less deactivation during films followed by less recovery from deactivation was found in asthma compared to healthy controls. Changes in PCO2 did not explain these findings. FENO was positively related to BOLD activation in general, but more pronounced in healthy controls and more likely in neutral film processing. Thus, asthma is associated with altered processing of film stimuli across brain regions not limited to central adaptive control, threat processing, or salience networks. Higher levels of NO appear to facilitate CNS activity, but only in healthy controls, possibly due to allergy's masking effects on FENO.

RESUMO

BACKGROUND: Major depressive disorder is common in people with asthma. Yet, few studies have evaluated depression treatment in those with asthma. OBJECTIVE: To explore the relationship between antidepressant use, depressive symptoms, and asthma control, pooled data from 3 randomized trials of either citalopram or escitalopram were assessed. METHODS: Linear fixed effects and binary logistic regression analyses were conducted with between-subject covariates including treatment group, (original) study, and demographics. The within-subject effect of visit, and a treatment group-visit (between-within) interaction effect, were also evaluated. Analyses were repeated in a high asthma exacerbation subgroup having at least 3 oral corticosteroid bursts in the previous 12 months. Outcomes included the Hamilton rating scale for depression (HAM-D17), the 7-item asthma control questionnaire (ACQ), and oral corticosteroid use (yes or no). RESULTS: In the pooled sample (n = 255), the antidepressant treatment group exhibited lower HAM-D17 overall (P ≤ .001) and a lower likelihood for oral corticosteroid use (P ≤ .001) relative to the placebo group. In the high-exacerbation subgroup (n = 96), treatment group participants had lower overall asthma control questionnaire (P = .004) and HAM-D17 scores (P ≤ .001), and a lower likelihood of oral corticosteroid use (P = .003), relative to placebo participants. All treatment group interaction effects were not significant. CONCLUSION: Citalopram or escitalopram exhibited efficacy in reducing depressive symptoms and the need for rescue oral corticosteroids in patients with asthma and major depressive disorder. Future work should determine whether selective serotonin reuptake inhibitors are effective at improving asthma outcomes in those with asthma who are not depressed. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT00621946 and NCT01324700 (one study was conducted before ClinicalTrials.gov requirements).

RESUMO

BACKGROUND: Depression and anxiety negatively affect asthma-related quality of life (QoL). Yet, little is known regarding mood and asthma-related factors that best uniquely explain asthma-related QoL in children. OBJECTIVE: This cross-sectional study evaluated the unique variance explained by caregiver and child depressive and anxiety symptom severity in child asthma-related QoL, apart from that explained by demographics and asthma control. METHODS: Children aged 7 to 17 years with asthma (n = 205) and their caregivers with major depressive disorder were included. A 3-stage hierarchical linear regression analysis was conducted with the Pediatric Asthma Quality of Life Questionnaire total scores considered as the outcome. Predictors included demographic characteristics (stage 1); asthma control assessed by the Asthma Control Test (stage 2); and caregiver depression and anxiety (Hamilton Rating Scale for Depression and the Spielberger State/Trait Anxiety Scale) and child depression and anxiety (Children's Depression Inventory and the Screen for Child Anxiety-Related Disorders) (stage 3). RESULTS: Demographic characteristics accounted for only 5.5% of the Pediatric Asthma Quality of Life Questionnaire scores. Asthma control significantly increased variance explained in QoL to 32.6%, whereas caregiver and child depression and anxiety symptoms significantly increased variance explained to 42.6%. Child anxiety was found to uniquely explain the largest proportion of variance in QoL (rs2 = 0.584). CONCLUSION: After adjusting variance in QoL for demographic characteristics and asthma control, caregiver and child depression and anxiety measures significantly increased the proportion of variance explained in a child's asthma-related QoL. In addition to better asthma control, child and caregiver depression and anxiety should be addressed to increase child asthma-related QoL.

RESUMO

Background: Clinical trials demonstrated that selective serotonin reuptake inhibitors (SSRI) can improve asthma control in patients with comorbid major depressive disorder (MDD) and that this effect may be greater than the effect of SSRIs on depression. These findings suggest that SSRIs may improve asthma control in patients without MDD. Objective: The current retrospective study examined the effect of SSRIs and serotonin and norepinephrine reuptake inhibitors (SNRI) on asthma control in adult patients. We hypothesized that patients would have fewer asthma exacerbations after treatment with an SSRI or SNRI. Methods: Electronic health record data of adult patients (N = 592) who were seen at a University of Texas Southwestern (UTSW) hospital or clinic and had (1) an SSRI or SNRI prescription, (2) a previous asthma diagnosis, and (3) no mood disorder diagnosis were extracted by using the UTSW Clinical Data Exchange Network. Wilcoxon signed rank tests were used to compare oral corticosteroid prescriptions and asthma-related emergency department (ED) visits and hospitalizations in the 12 months before and after the start of an SSRI/SNRI. Results: Therapy with SSRIs/SNRIs was associated with a significant decrease in oral corticosteroid use (p = 0.003), ED visits (p = 0.002), and hospitalizations (p < 0.001). Conclusion: Results from the current study add to the existing literature by demonstrating a reduced rate of severe exacerbations in patients with asthma by using an SSRI/SNRI without limiting the analytic sample to a high-illness-severity subgroup defined by symptoms of asthma or depression. Future work should include a prospective, placebo controlled study with individuals who have asthma and no comorbid mental health condition, verified by a mental health professional.

RESUMO

BACKGROUND: Identifying individuals at increased risk of suicide is important, particularly those who present for treatment for nonpsychiatric chief complaints who may go undetected. It has been found that pain symptoms, such as headache, are associated with suicide, although this association requires further characterization. This study examined specific components of suicidality in relation to headache subtypes. METHODS: This study retrospectively reviewed 2,832,835 nonpsychiatric adult clinical encounters at a large county hospital, where a standardized suicide risk screening tool, the Columbia-Suicide Severity Rating Scale (C-SSRS), was universally implemented. The C-SSRS assesses specific components of suicidality: wish to be dead and suicidal ideation, method, intent, plan, and action. Multivariate logistic regressions were performed to assess the association between headache, as well as headache subtype (migraine, tension, or cluster), and each component of suicidality. RESULTS: There were significant positive associations between presenting with a headache and 2 specific components of suicidality: wish to be dead and suicidal action. Individuals with tension headache may have a lower risk of wishing to be dead compared to those with migraine and cluster headaches. CONCLUSIONS: The association of headaches with specific elements of sui-cidality demonstrates the potential yield of identification of suicide risk among individuals with nonpsychiatric presentations.

RESUMO

BACKGROUND: Past research shows a dual role of organizational reputation in an employment context. Prospective and current employees are affected by public perceptions of their employer, as affiliation with an employer widely known for its positive achievements boosts organization-based self-esteem whereas a poor reputation leads to decreased self-esteem and disassociation. Another key construct is engagement, which relates to employee enthusiasm and their attitude toward the organization and their interest in finding employment elsewhere. PURPOSE: The current study examined relationships between engagement, organizational pride, perceived departmental and institutional reputation, and turnover intentions in employees at an academic medical center. METHODS: Participants were 241 faculty, staff, and trainees (63.9% women) in a clinical department at an academic medical center who completed an anonymous online survey that contained the Utrecht Work Engagement Scale, as well as questions about pride, reputation, and turnover intentions. Relationships between engagement, organizational pride, perceived departmental and institutional reputation, and turnover intentions were explored. RESULTS: To determine whether employee engagement mediates the relationship between various predictors and turnover intentions, exploratory mediation models were examined. All of the variables were significantly correlated with each other. Perception of departmental reputation was more strongly associated with engagement, pride, and turnover intentions than was institutional reputation. Engagement fully mediated the relationship between perceived institutional reputation and turnover intentions and partially mediated relationships between departmental reputation and turnover intentions and between pride and turnover intentions. PRACTICE IMPLICATIONS: The findings suggest that perception of one's department may be more important to engagement and pride than perception of the larger institution. Furthermore, relationships between pride and reputation and turnover intentions in an academic medical center appear to be, at least partially, mediated through engagement. In contrast to common practice, turnover reduction efforts might be more effective if they enhance perceived departmental, rather than institutional, reputation.

RESUMO

BACKGROUND: Delirium is a major source of morbidity in the inpatient hospital setting. This study examined differences between patients with delirium present prior to hospital admission and those with hospitalacquired delirium in several health outcomes. METHODS: A total of 12,529 patients on 2 inpatient units were included in this retrospective cohort study. Outcomes were assessed using chart review. Other variables were compared across groups and included in multivariate models predicting discharge location within the hospitalacquired delirium group. RESULTS: Of 709 patients with delirium, 83% had pre-admission prevalent and 17% had post-admission incident delirium. Compared with patients with preexisting delirium, patients with hospital-acquired delirium had greater hospital durations and mortality and were more likely to receive ICU care, more likely to receive multiple classes of medications, and less likely to be discharged home without home health services. Multivariate analysis in the hospital-acquired delirium group found that several variables independently predicted discharge location. CONCLUSIONS: Patients with hospital-acquired delirium had worse hospital outcomes and a more complicated hospital course than those with preexisting delirium. Administration of various medications, several demographic variables, and some hospital-related variables were independently associated with worse outcomes within the hospital-acquired delirium group. These results demonstrate that patients with hospitalacquired delirium are a vulnerable subgroup deserving special attention.

RESUMO

Little is known about relationships between state mental health expenditures and outcomes. This analysis evaluated relationships between spending and income across the states and mental health outcomes. Relationships between state per capita SMHA and Medicaid mental health spending, as well as median household income, percent of residents on Medicaid and Mental Health America (MHA) ranking, suicide and incarceration rates were assessed using correlations and multiple regressions. Median household income predicted MHA overall and youth ranking. Per capita Medicaid mental health spending predicted MHA prevalence ranking. Median household income and Medicaid spending predicted access to care ranking and incarcerations. Median income, Medicaid spending and percent receiving Medicaid predicted suicide rate. The findings suggest median household income may, in some cases, predict mental health treatment quality and outcomes more strongly than spending. However, the relationship with per capita mental health Medicaid spending on outcomes is also noteworthy.

RESUMO

OBJECTIVE: To analyze the risk of megestrol, a glucocorticoid and progesterone receptor agonist used to enhance appetite, on the development of a new psychiatric diagnosis. DESIGN AND PARTICIPANTS: Deidentified data of megestrol (n = 706) and propensity score-matched comparison (age, gender, and body mass index) patients (n = 2,118) from January 1, 2001 to June 30, 2018 were obtained from the UT Southwestern patient database. Data were analyzed using a series of conditional binary logistic regressions controlling for comorbidities, pre-existing psychiatric disorders, and number of patient encounters. SETTING: A large academic medical center database of megestrol-treated patients and matched comparison patients was used. MEASUREMENTS AND RESULTS: The regression model showed that megestrol was significantly associated with developing a new psychiatric diagnosis (B = 1.28, Wald χ21 = 83.12, odds ratio [OR] = 3.60, p <0.001). In subgroup analyses, development of cognitive (B = 2.42, Wald χ21 = 16.09, OR = 11.30, p <0.001), mood (B = 1.31, Wald χ21 = 40.38, OR = 3.70, p <0.001), and anxiety (B = 1.72, Wald χ21 = 45.28, OR = 5.60, p <0.001) disorders were also associated with megestrol use. CONCLUSIONS: Patients taking megestrol were significantly more likely to develop a new psychiatric diagnosis than comparison patients. Highest risks were associated with the development of cognitive diagnoses. The findings suggest that megestrol, like other glucocorticoid agonists, is associated with an increased risk of developing a psychiatric disorder. This risk should be considered when determining the risk-to-benefit ratio of megestrol use in patients.

RESUMO

PURPOSE/BACKGROUND: Glucocorticoids are a class of hormones that include naturally occurring cortisol and corticosterone, as well as prescription drugs commonly used to manage inflammatory, autoimmune, and allergic conditions. Adverse effects, including neuropsychiatric symptoms, are common. The hippocampus appears to be especially sensitive to the effects of glucocorticoids. However, to our knowledge, no studies to date have examined hippocampal subfields in humans receiving glucocorticoids. We examined patients on chronic glucocorticoid regimens to determine relationships between dose and duration of treatment, and hippocampal subfields, and related regions volumes. METHODS/PROCEDURES: The study included adult men and women receiving at least 5 mg daily of prednisone equivalents for at least 6 months. Volumes of brain regions were measured via magnetic resonance imaging. A multivariate general linear model was used for analysis, with brain volumes as dependent variables and age, sex, and cumulative corticosteroid exposure, as predictors. FINDINGS/RESULTS: The study population consisted of 81 adult outpatients (43 male) on corticosteroids (mean dose, 7.88 mg; mean duration, 76.75 months). Cumulative glucocorticoid exposure was negatively associated with left and right hippocampal dentate gyrus/CA3 volume. In subsequent subgroup analysis, this association held true for the age group older than the median age of 46 years but not for the younger age group. IMPLICATIONS/CONCLUSIONS: This finding is consistent with previous studies showing detrimental effects of elevated glucocorticoids on the hippocampus but further suggests that the dentate gyrus and CA3 regions are particularly vulnerable to those effects, which is consistent with animal models of chronic stress but has not been previously demonstrated in humans.

RESUMO

BACKGROUND: Alcohol use disorder is a major societal and individual burden that exacerbates health outcomes, decreases quality of life, and negatively affects U.S. healthcare spending. Although pharmacological treatments are available for alcohol use disorder, many of them are limited by small effect sizes and used infrequently. Citicoline is a widely available over-the-counter supplement with a favorable side effect profile. It acts through cholinergic pathways and phospholipid metabolism. The current report examines the effect of oral citicoline on alcohol use, craving, depressive symptoms, and cognitive outcomes in individuals with alcohol use disorder. METHODS: A 12-week, randomized, double-blind, parallel-group, placebo-controlled, pilot study of citicoline (titrated to 2,000 mg/d) in 62 adults (age 18 to 75) with alcohol use disorder was conducted. Alcohol use, such as number of drinking days, amount used, and number of heavy drinking days, was assessed using the Timeline Followback method and liver enzymes, while alcohol craving was measured using the Penn Alcohol Craving Scale. A neurocognitive battery (e.g., Rey Auditory Verbal Learning Test) and depressive symptoms scale (e.g., Inventory of Depressive Symptomatology Self-Report) scores were also collected. Data were analyzed using a random regression analysis. RESULTS: The primary outcome analysis was conducted in the intent-to-treat sample and consisted of 55 participants (78.2% men and 21.8% women, mean age of 46.47 ± 9.15 years). In the assessment period, the drinking days, on average, represented 77% of the assessed days. Significant between-group differences were not observed on alcohol use, craving, and cognitive or depressive symptom measures. Citicoline was well tolerated. CONCLUSIONS: This proof-of-concept study observed that citicoline was well tolerated, but was not associated with a reduction in alcohol use or other outcomes, as compared to placebo. The favorable effects reported with citicoline for cocaine use, cognitive disorders, and other conditions do not appear to extend to alcohol use disorder.

RESUMO

BACKGROUND: Several single-site alcohol treatment clinical trials have demonstrated efficacy for immediate-release (IR) gabapentin in reducing drinking outcomes among individuals with alcohol dependence. The purpose of this study was to conduct a large, multisite clinical trial of gabapentin enacarbil extended-release (GE-XR) (HORIZANT® ), a gabapentin prodrug formulation, to determine its safety and efficacy in treating alcohol use disorder (AUD). METHODS: Men and women (n = 346) who met DSM-5 criteria for at least moderate AUD were recruited across 10 U.S. clinical sites. Participants received double-blind GE-XR (600 mg twice a day) or placebo and a computerized behavioral intervention (Take Control) for 6 months. Efficacy analyses were prespecified for the last 4 weeks of the treatment period. RESULTS: The GE-XR and placebo groups did not differ significantly on the primary outcome measure, percentage of subjects with no heavy drinking days (28.3 vs. 21.5, respectively, p = 0.157). Similarly, no clinical benefit was found for other drinking measures (percent subjects abstinent, percent days abstinent, percent heavy drinking days, drinks per week, drinks per drinking day), alcohol craving, alcohol-related consequences, sleep problems, smoking, and depression/anxiety symptoms. Common side-effects were fatigue, dizziness, and somnolence. A population pharmacokinetics analysis revealed that patients had lower gabapentin exposure levels compared with those in other studies using a similar dose but for other indications. CONCLUSIONS: Overall, GE-XR at 600 mg twice a day did not reduce alcohol consumption or craving in individuals with AUD. It is possible that, unlike the IR formulation of gabapentin, which showed efficacy in smaller Phase 2 trials at a higher dose, GE-XR is not effective in treating AUD, at least not at doses approved by the U.S. Food and Drug Administration for treating other medical conditions.

RESUMO

AIMS: The objective of this study is to address equivocation in estimates of selective serotonin reuptake inhibitor initiation (SSRI) effect on all-cause and alcohol-related ER visits, and medical or psychiatric admissions within 2 years of initial Post-Traumatic Stress Disorder (PTSD) diagnosis in patients with PTSD and Alcohol Use Disorder (AUD). METHODS: This study is a quasi-experimental, new-user-design cohort study of 3235 patients seen at the VA North Texas Healthcare System between January 1, 2000 and December 31, 2016. High dimensional propensity score (HDPS) techniques were used to estimate likelihood of SSRI initiation within 30 days of first PTSD diagnosis. Propensity scores were used to calculate weights for likelihood of SSRI initiation which were used to control for baseline covariates in estimations of SSRI medication effect on odds of each outcome occurring. RESULTS: Compared to those who did not receive SSRIs, patients prescribed an SSRI within 30 days showed significantly lower odds of alcohol-related ER visits (OR=0.668, 95%CI = 0.476 to 0.938, P = 0.02) and alcohol-related medical admissions (OR=0.583, 95%CI = 0.399 to 0.851, P = 0.005). LIMITATIONS: Inconsistent assessment of PTSD severity necessitated the use of HDPS models to control for baseline confounding. Our study design mimicked intent-to-treat trial design and therefore could not control for SSRI initiations after the 30-day grace period following initial PTSD diagnosis. CONCLUSIONS: SSRI initiation in patients with AUD and PTSD is associated with significantly reduced odds of alcohol-related medical hospitalization and alcohol-related ER visits within 2 years of first PTSD diagnosis. Additional studies are needed to verify these results.

RESUMO

Background: Bupropion is a substituted cathinone compound widely used as a first line or add-on treatment for depression, smoking cessation, and more recently in combination with naltrexone for weight loss. As abuse of synthetic cathinone compounds has received more attention in recent years, concern about the misuse potential of bupropion has grown as well. Objectives: We review bupropion pharmacology and assessments of misuse potential including preclinical evidence, human studies, and post-marketing surveillance of bupropion misuse. Methods: This review reports the results of a systematic review of publications evaluating the potential for bupropion to be misused. Publications were identified using PubMed and Medline through Ovid® as well as iterative bibliographic searches. A summary of data from informal sources of information including substance-user experience from online forum entries is included. Results: Preclinical evidence demonstrates some potential for misuse based on psychomotor, discrimination, self-administration, and conditioned place preference tasks. However, this potential is less than that of commonly misused stimulants. Studies in human populations similarly indicate that bupropion shares interoceptive effects with other stimulants, but lacks some key reinforcing effects of other stimulants. In the real-world setting, misuse of bupropion occurs, but is uncommon. Adverse effects of bupropion misuse are frequently cited as significant barriers to obtaining any desired interoceptive effect. Conclusions: While bupropion demonstrates some potential for misuse, pharmacological differences from other structurally-related stimulants limit bupropion's reinforcing effects. Without additional data indicating susceptibility of specific populations to bupropion misuse, there is no empirical data suggesting a need to modify bupropion prescribing patterns.

RESUMO

BACKGROUND: The effects of the glucocorticoid and progesterone receptor agonist megestrol on declarative memory, and the ability of phenytoin to block these effects, were assessed. METHODS: Healthy volunteers received each medication combination (placebo and megestrol, phenytoin and megestrol, and placebo and placebo) using a randomized, crossover design. The Rey Auditory Verbal Learning Test assessed declarative memory. RESULTS: Megestrol was associated with a significant reduction in declarative memory (p = 0.0008), which was attenuated by phenytoin, and was associated with significant cortisol suppression compared to placebo (p < 0.001). CONCLUSION: Changes in memory and cortisol suppression were found in healthy volunteers given megestrol.

RESUMO

OBJECTIVE: To review the literature regarding the effects of caregiver depression on childhood asthma and integrate the findings into a multilevel model of pathways by which these effects occur to further the understanding of the complex biopsychosocial nature of childhood asthma and the key role that is played by caregiver depression. DATA SOURCES: PubMed was searched for articles published from 2007 to the present (10-year search), and Google Scholar was searched for articles published in 2017 and 2018 to identify the most recent publications. STUDY SELECTIONS: Studies selected were recent, empirical, or meta-analytic, conducted in humans, and had specific relevance to one or more of the identified pathways. Articles published before 2007 were included if deemed essential because they addressed key pathways, for which there were no more recent articles. RESULTS: Review of the literature substantiates that caregiver depression plays a key role in the socioeconomic, familial, psychological, and biological cascade of effects on childhood asthma. Childhood asthma outcomes are affected indirectly by socioeconomic status and family stress mediated by caregiver depression, which affects disease management, and/or stress and depression in the child, which, in turn, affect asthma through alterations in immune modulation and autonomic regulation. CONCLUSION: Findings indicate that future research should concentrate on mediators and moderators to further clarify the complex interplay of these factors that affect childhood asthma. The findings also have substantial translational implications. Given that child stress and depression contribute to asthma disease activity and that treating caregiver depression improves child stress and depression, there is strong rationale for treating depressed caregivers of children with asthma as a component means of improving childhood asthma control.

RESUMO

OBJECTIVE: Asthma is an increasingly prevalent disease that is associated with substantial physical and financial burdens. Additionally, asthma is linked to psychiatric disorders. This study examines the relationship between asthma diagnosis, current depressive symptoms, and lifetime psychiatric disorder history in a large, community-based sample. METHODS: We analyzed data from 2168 participants in the Dallas Heart Study, a large, diverse, community-based sample of people designed to be representative of the Dallas County population. Logistic regressions analyzing the relationship between asthma diagnosis and history of a psychiatric disorder, as well as between asthma diagnosis and the Quick Inventory of Depressive Symptomatology (QIDS) scores were performed, controlling for demographic data. RESULTS: 13.4% of the sample had an asthma diagnosis. Asthma diagnosis was significantly associated with a history of nervous, emotional, or mental health disorder diagnosis [OR 1.810 (95% CI 1.280-2.559) p = 0.001], and with QIDS scores consistent with moderate or greater current depressive symptom severity [OR 1.586 (95%CI 1.106-2.274) p = 0.012]. The relationships were not moderated by age, gender, race, smoking status, or Body Mass Index. CONCLUSIONS: A diagnosis of asthma may be associated with current clinically significant levels of depressive symptoms and a lifetime psychiatric disorder. The current report adds to the existing literature in this area by assessing both current and lifetime symptoms and by using a large and diverse population. The findings highlight the clinical importance of considering the possibility of psychiatric illness in asthma patients and suggest further research in this area is needed.

RESUMO

AIMS: The current study examined a large community cohort to understand relationships between indicators of alcohol consumption and hippocampal volume. SHORT SUMMARY: Alcohol use measures were not associated with hippocampal volume in a population-based sample. However, alcohol consumption was associated with hippocampal volume reduction in subsets of the sample including subjects aged ≥50 years old, and those with none to moderate levels of depressive symptoms. METHODS: A total of 1848 adults with magnetic resonance imaging (MRI) and alcohol consumption data were included. Multiple linear regressions were performed with left or right hippocampal volume as dependent variables, and age, gender, race, education, body mass index, Quick Inventory of Depressive Symptomatology (QIDS-SR) scores, drinks per week (DPW), aspartate aminotransferase (AST), alanine aminotransferase (ALT), AST/ALT, γ-glutamyl transferase and mean corpuscular volume (MCV) as independent variables. Post hoc analyses were conducted to assess interactions of demographic factors and variables of interest (DPW, AST, ALT, AST/ALT, GGT and MCV). For statistically significant interactions, analyses were conducted in groups split by gender, depression (QIDS-SR scores ≥11 and <11) and age (≥50 and <50 years). RESULTS: Average alcohol consumption in the population was low (µ = 2.95 ± 6.7 DPW). Alcohol consumption measures were not significantly associated with hippocampal volume in the primary analysis. Exploratory analyses revealed significant associations between DPW and right hippocampal volume in participants with QIDS-SR scores <11 (B = -3.75, P = 0.02, CI = -6.97, -0.52) and in those aged ≥50 years (B = -4.844, P = 0.023 CI = -9.023 to -0.664). AST/ALT was significantly associated with right (B = -93.66, P = 0.022, CI = -173.64 to -13.68) and left hippocampal volume (B = -109.79 P = 0.008, CI = -190.97 to -28.61) in participants aged ≥50 but not <50 years. Gender differences were not observed. CONCLUSIONS: The findings suggest a relationship between alcohol use indicators and right hippocampal volume in non-depressed and older adults.

RESUMO

Background With the increase use of pay for performance in healthcare, 30-day readmissions after discharges are critically important. Objective A team-based psychiatric consultation approach was tested in an inpatient hospital setting. This is the first study that examines 30-day readmission rate with this approach. Methods In this quality improvement study, 164 patients received a team-based psychiatric consultation that included daily meetings during the weekdays between psychiatrists and hospitalists and 436 received care of treatment-as-usual or traditional consultation-liaison services. Results Overall 30-day readmission rate was not significantly different between intervention and nonintervention groups. However, in subgroups with high risk of mortality or severe illness, the intervention group had a 0% 30-day readmission rate for both high risk of mortality and severe illness subgroups, while the nonintervention group's readmission rate was 5% for high risk of mortality group and 3% for severely ill patients. Annual hospital cost saving is estimated between a quarter million and 1.5 million dollars for these subgroups. Conclusion The team-based psychiatric consultation approach demonstrated the potential for substantial cost savings in providing care for patients with high risk of mortality and severe illness. Thus, this intervention may be very useful in caring for patients with complex chronic conditions.
