RESUMO

This study investigated longitudinal trajectories of anxiety and depressive symptoms following moderate-severe traumatic brain injury (TBI), predictors of the trajectories, and associations with 1-year return to productivity. One hundred forty-eight patients with moderate-severe TBI were assessed at 2, 5, 12, and ≥36 months post-injury on the Beck Anxiety Inventory and the Beck Depression Inventory. Clinical interviews obtained information about demographics, injury characteristics, and 1-year return to productivity. Latent growth mixture modeling identified trajectories of anxiety and depression across time. The three-step method identified predictors of trajectories, and χ2 analyses determined associations between trajectories and 1-year return to productivity. Analyses revealed that four-class models of anxiety and depression best fit the data. Most individuals had stable minimal (67%) or low (18%) levels of anxiety over time. Two other subsets of individuals were classified by anxiety that worsened rapidly (7%) or improved in the 1st year but worsened by 3 years post-injury (9%). Similarly for the depression trajectories, most individuals had stable minimal (70%) or low (10%) levels of depression over time. Others had depression that worsened rapidly (12%) or was delayed, with onset 1-year post-injury (8%). Predictors of worsening anxiety and depression included younger age, less education, and male gender. Those with worsening anxiety or depression were less likely to return to productivity by 1-year post-injury. There is a significant burden of anxiety (15%) and depression (20%) in the 3 years after moderate-severe TBI. Future research targeting at-risk patients may help to improve quality of life and functional recovery.

RESUMO

Background: Increases in the incidence of psychological distress and alcohol use during the COVID-19 pandemic have been predicted. Behavioral theories of depression and alcohol self-medication theories suggest that greater social/environmental constraints and increased psychological distress during COVID-19 could result in increases in depression and drinking to cope with negative affect. The current study had two goals: (1) to examine self-reported changes in alcohol use and related outcomes after the introduction of COVID-19 social distancing requirements, and; (2) to test hypothesized mediation models to explain individual differences in self-reported changes in depression and alcohol use during the early weeks of the COVID-19 pandemic. Methods: Participants (n = 833) were U.S. residents recruited for participation in a single online survey. The cross-sectional survey included questions assessing environmental reward, depression, COVID-19-related distress, drinking motives, and alcohol use outcomes. Outcomes were assessed via retrospective self-report for two timeframes in the single survey: the 30 days prior to state-mandated social distancing ("pre-social-distancing"), and the 30 days after the start of state-mandated social distancing ("post-social-distancing"). Results: Depression severity, coping motives, and some indices of alcohol consumption (e.g., frequency of binge drinking, and frequency of solitary drinking) were significantly greater post-social-distancing relative to pre-social-distancing. Conversely, environmental reward and other drinking motives (social, enhancement, and conformity) were significantly lower post-social distancing compared to pre-social-distancing. Behavioral economic indices (alcohol demand) were variable with regard to change. Mediation analyses suggested a significant indirect effect of reduced environmental reward with drinking quantity/frequency via increased depressive symptoms and coping motives, and a significant indirect effect of COVID-related distress with alcohol quantity/frequency via coping motives for drinking. Discussion: Results provide early cross-sectional evidence regarding the relation of environmental reward, depression, and COVID-19-related psychological distress with alcohol consumption and coping motives during the early weeks of the COVID-19 pandemic. Results are largely consistent with predictions from behavioral theories of depression and alcohol self-medication frameworks. Future research is needed to study prospective associations among these outcomes.

RESUMO

BACKGROUND: The acquired preparedness model (APM) posits that relationships between impulsivity-related traits and alcohol use are partly mediated by the biased acquisition of positive alcohol expectancies. Additionally, alcohol administration studies implicate associations between impulsivity-related traits and sensitivity to acute alcohol effects, suggesting that impulsivity-expectancy associations could be partly explained by individual differences in alcohol response. The present study assessed a theoretical extension of the APM by testing the prediction that self-reported sensitivity to alcohol would partly mediate impulsivity-expectancy relationships, and that the addition of alcohol sensitivity variables would account for increased variance in drinking quantity and problems relative to the traditional APM. METHOD: Young adult heavy drinkers (N = 300, 53% women) completed the Alcohol Sensitivity Questionnaire, the UPPS-P Impulsive Behavior Scale, and measures of alcohol expectancies (Comprehensive Effects of Alcohol Questionnaire) and drinking quantity and related problems. Hypotheses were examined using path analysis. RESULTS: Results supported significant indirect effects of sensation seeking on drinking quantity and problems via higher positive expectancies. Results also supported a significant indirect effect of negative urgency on drinking problems via negative expectancies. Although alcohol sensitivity variables showed unique associations with drinking outcomes, the addition of these variables did not improve model fit and hypothesized indirect paths involving impulsivity-related traits, alcohol sensitivity, and expectancies were not supported. CONCLUSIONS: Future research is necessary to reconcile these results with laboratory findings suggesting that impulsive traits are frequently associated with sensitivity to alcohol's acute effects.

RESUMO

OBJECTIVE: This study examined the physical and mental health of Cree adults, as well as the personal, clinical, and environmental factors associated with the presence of lifetime anxiety and mood disorders. METHODS: Mental health was assessed using the computerised version of the Diagnostic Interview Schedule (CDIS-IV), and standardised instruments were used to assess physical health, addiction severity, and psychological distress in 506 randomly selected participants from 4 Northern Cree communities in Quebec. RESULTS: Overall, 46.1% of participants reported chronic medical problems, 42.1% were current smokers and 34.5% met the DSM-IV criteria for an anxiety or mood disorder. Individuals with an anxiety or mood disorder were younger, predominantly female, and with higher educational levels, and a large proportion (47.7%) met the lifetime criteria for substance dependence. Hierarchical regression determined that anxiety or mood disorders were associated with serious problems getting along with parents, a history of physical and sexual abuse, and a lifetime diagnosis of substance dependence. Overall, 29.7% of Cree adults reported sexual abuse, 47.1% physical abuse, and 52.9% emotional abuse. CONCLUSIONS: This study highlights the high rates of physical and mental health problems in Cree communities and the association among parental history of psychological problems, history of abuse, and psychological distress. Participants expressed a desire for additional medical and psychological treatments to address the patterns of abuse, trauma, and mental disorders that are burdening the Cree communities in Northern Quebec.

RESUMO

The Personality Inventory for DSM-5 (PID-5) is a questionnaire developed to assess the five domains represented in the alternative model for personality disorders proposed in Section III of the DSM-5. This study examined the ability of the PID-5 to distinguish between different mental disorders compared to a questionnaire measure of the five-factor model (FFM) of normative personality. The study included the administration of the PID-5 and Revised NEO Personality Inventory (NEO PI-R), a measure of the FFM, to treatment-seeking individuals with Depressive, Bipolar, Psychotic, and Alcohol Use Disorders (AUD). Diagnostic groups were compared at the domain level of PID-5 and NEO PI-R, with sex and age as covariates. The main findings on the PID-5 included higher Detachment scores for Bipolar and Depressive Disorders than Psychotic and AUDs, lower Psychoticism/higher Disinhibition scores for the AUD group compared to all other groups, and lower Negative Affect for the Psychotic Disorders versus AUD group. On the NEO PI-R, the AUD diagnostic group was associated with lower Conscientiousness and Agreeableness scores compared to all other groups, and lower Neuroticism scores than the Bipolar and Depressive groups. Group pairwise comparisons did not appear to show many differences between the PID-5 and NEO PI-R. The results suggest that the alternative DSM-5 model for personality disorders may have clinical utility in distinguishing personality profiles between diagnostic groups. These findings emphasize the importance of additional research on the capacity of maladaptive personality to contribute to the assessment of differential diagnoses.

RESUMO

Despite high prevalence rates of concurrent borderline personality disorder (BPD) and substance use disorders (SUDs), little is known about the impact of substance misuse on the presentation of BPD. Sixty-five individuals with BPD were assessed at intake and at 3- and 6-month follow-up. Assessment included validated instruments such as the Addiction Severity Index and the Revised Symptom Checklist (SCL-90-R). Over half (58.5%) of individuals entering treatment were currently misusing substances. Substance misuse was associated with more legal and employment problems, greater mood disturbance, impulsivity, and psychiatric severity, including almost all SCL-90-R subscales. For the majority of patients (58%), there was little change in substance misuse post-treatment. The high prevalence of substance misuse and its association with psychiatric severity among individuals with BPD suggest that substance misuse should be a targeted behavior during treatment, and further specialized interventions are needed for individuals with comorbid BPD and SUD.

RESUMO

Research has demonstrated that about 30% of chronic pain patients suffer from borderline personality disorder (BPD), yet pain is not often discussed in research on the treatment of BPD. Sixty-five patients entering outpatient treatment for BPD were assessed at baseline for the prevalence of DSM-IV lifetime pain disorder, current medical problems, and the experience of current pain as measured by the McGill Pain Questionnaire. DSM-IV lifetime pain disorder diagnosis was present in 65% of patients. Current pain was experienced by 89% of participants, with intensity ranging from mild (19%) to excruciating (2%). Some individuals (21.5%) also reported experiencing daily medical problems in the past month prior to entering treatment. Physical pain is highly prevalent among treatment-seeking individuals with BPD. This pain phenomenon should be considered during treatment to help prevent a lifetime of functional impairment, including the possibility of abusing substances as a maladaptive coping mechanism.

RESUMO

BACKGROUND: Huntington's disease (HD) is a fatal progressive neurodegenerative disease characterized by chorea, cognitive impairment and psychiatric symptoms. Retinal examination of HD patients as well as in HD animal models have shown evidence of retinal dysfunction. However, a detailed retinal study employing clinically available measurement tools has not been reported to date in HD. OBJECTIVE: The goal of this study was to assess retinal responses measured by electroretinogram (ERG) between HD patients and controls and evaluate any correlation between ERG measurements and stage of disease. METHODS: Eighteen patients and 10 controls with inclusion criteria of ages 18-70 years (average age HD subjects: 52.1 yrs and control subjects: 51.9 yrs) were recruited for the study. Subjects with previous history of retinal or ophthalmologic disease were excluded. Retinal function was examined by full-field ERG in both eyes of each subject. Amplitudes and latencies to increasing flash intensities in both light- and dark-adaptation were measured in all subjects. Statistical analyses employed generalized estimating equations, which account for repeated measures per subject. RESULTS: We analyzed the b-wave amplitudes of ERG response in all flash intensities and with 30 Hz flicker stimulation. We found statistically significant increased amplitudes in HD patients compared to controls at light-adapted (photopic) 24.2 and 60.9 cd.sec/m2 intensities, dark-adapted (scotopic, red flash) 0.22 cd.sec/m2 intensity, and a trend toward significance at light-adapted 30 Hz flicker. Furthermore, we found a significant increase in light-adapted ERG response from female compared to male HD patients, but no significant difference between gender amongst controls. We also noted a positive association between number of CAG repeats and ERG response at the smallest light adapted intensity (3.1 cd.sec/m2). CONCLUSIONS: ERG studies revealed significantly altered retinal responses at multiple flash intensities in subjects with an HD expansion allele compared to controls. Significant differences were observed with either light-adapted tests or the dark-adapted red flash which suggests that the enhanced responses in HD patients is specific to the cone photoreceptor pathway.

RESUMO

A detailed survey of gambling, addiction and mental health was conducted with randomly selected respondents (n = 506) from four Cree communities of Northern Quebec. The study examined the current patterns of gambling in relation to demographic, social, and psychological factors. Instruments included the Canadian Problem Gambling Index, Addiction Severity Index, Beck Depression Inventory and the computerized Diagnostic Interview Schedule for psychiatric diagnoses. Overall, 69.2 % of the total sample participated in any gambling/gaming activities over the past year; 20.6 % of this group were classified as moderate/high risk gamblers, and 3.2 % were classified in the highest "problem gambling" category. Considering the entire sample, the overall prevalence of problem gambling was 2.2 %. Women were significantly more likely to play bingo (56.6 %) compared to men (35.1 %) and they played more frequently; 20.8 % of women versus 3.8 % of men played once/week or more often. Compared to the no/low risk gamblers, a greater proportion of moderate/high risk gamblers were cigarette smokers (44.8 vs. 56.3 %), they were more likely to meet DSM-IV diagnostic criteria for alcohol dependence (21.2 vs. 46.2 %), and they were more likely to report moderate to severe depressive symptoms in the past month. Risk factors for problem gambling included traumatic life events (physical and emotional abuse), anxiety and depression, as well as drug/alcohol abuse. The high rates of comorbidity between problem gambling, tobacco dependence, substance abuse and other psychological problems demonstrate that gambling among some Cree adults is part of a pattern of high-risk factors for negative long-term health consequences. The results also have implications for treatment, suggesting that interventions for gambling disorders should not focus on gambling alone but rather the constellation of high-risk behaviours that pose a risk to recovery and well-being.

RESUMO

BACKGROUND: Previous research on the use of selective serotonin reuptake inhibitors (SSRIs) as a treatment for alcohol dependence has yielded mixed results. Depression has been shown to be a predictor of relapse and poor outcome following treatment, and it has been hypothesized that SSRIs would be beneficial in reducing drinking in depressed alcohol-dependent individuals. This randomized, double-blind, placebo-controlled trial was designed to test the effects of citalopram on treatment outcomes among alcohol-dependent individuals with and without depression. METHODS: Two hundred and sixty-five patients meeting criteria for a DSM-IV diagnosis of alcohol abuse or dependence were randomly assigned to receive placebo or citalopram 20 mg per day for the first week, followed by 40 mg per day from weeks 2 through 12. All patients received a standard course of treatment consisting of weekly individual and group psychotherapy. Participants were reassessed at 12 weeks, including dropouts from both treatment groups to determine rates of abstinence, changes in alcohol use, addiction severity, depressive symptoms, and psychiatric status. RESULTS: Citalopram provided no advantage over placebo in terms of treatment outcomes, and for some measures, citalopram produced poorer outcomes. Patients in the citalopram group had a higher number of heavy drinking days throughout the trial, and smaller changes in frequency and amount of alcohol consumption at 12 weeks. There was no influence of depression severity on outcomes in either medication group. Survival analyses also indicated no differences between depressed and nondepressed patients in the citalopram group for time to first slip or relapse. A diagnosis of personality disorder was associated with poorer treatment responses overall, regardless of treatment condition. CONCLUSIONS: This trial does not support the use of citalopram in the treatment of alcohol dependence. The results suggest that the use of SSRIs among depressed and nondepressed alcohol-dependent individuals early in recovery, prior to the onset of abstinence, may be contraindicated.

RESUMO

BACKGROUND: Whether unique human immunodeficiency type 1 (HIV) genotypes occur in the genital tract is important for vaccine development and management of drug resistant viruses. Multiple cross-sectional studies suggest HIV is compartmentalized within the female genital tract. We hypothesize that bursts of HIV replication and/or proliferation of infected cells captured in cross-sectional analyses drive compartmentalization but over time genital-specific viral lineages do not form; rather viruses mix between genital tract and blood. METHODS: Eight women with ongoing HIV replication were studied during a period of 1.5 to 4.5 years. Multiple viral sequences were derived by single-genome amplification of the HIV C2-V5 region of env from genital secretions and blood plasma. Maximum likelihood phylogenies were evaluated for compartmentalization using 4 statistical tests. RESULTS: In cross-sectional analyses compartmentalization of genital from blood viruses was detected in three of eight women by all tests; this was associated with tissue specific clades containing multiple monotypic sequences. In longitudinal analysis, the tissues-specific clades did not persist to form viral lineages. Rather, across women, HIV lineages were comprised of both genital tract and blood sequences. CONCLUSIONS: The observation of genital-specific HIV clades only in cross-sectional analysis and an absence of genital-specific lineages in longitudinal analyses suggest a dynamic interchange of HIV variants between the female genital tract and blood.

RESUMO

To evaluate human immunodeficiency virus type 1 (HIV-1) replication and selection of drug-resistant viruses during seemingly effective highly active antiretroviral therapy (HAART), multiple HIV-1 env and pol sequences were analyzed and viral DNA levels were quantified from nucleoside analog-experienced children prior to and during a median of 5.1 (range, 1.8 to 6.4) years of HAART. Viral replication was detected at different rates, with apparently increasing sensitivity: 1 of 10 by phylogenetic analysis; 2 of 10 by viral evolution with increasing genetic distances from the most recent common ancestor (MRCA) of infection; 3 of 10 by selection of drug-resistant mutants; and 6 of 10 by maintenance of genetic distances from the MRCA. When four- or five-drug antiretroviral regimens were given to these children, persistent plasma viral rebound did not occur despite the accumulation of highly drug-resistant genotypes. Among the four children without genetic evidence of viral replication, a statistically significant decrease in the genetic distance to the MRCA was detected in three, indicating the persistence of a greater number of early compared to recent viruses, and their HIV-1 DNA decreased by > or =0.9 log(10), resulting in lower absolute DNA levels (P = 0.007). This study demonstrates the variable rates of viral replication when HAART has suppressed plasma HIV-1 RNA for years to a median of <50 copies/ml and that combinations of four or five antiretroviral drugs suppress viral replication even after short-term virologic failure of three-drug HAART and despite ongoing accumulation of drug-resistant mutants. Furthermore, the decrease of cellular HIV-1 DNA to low absolute levels in those without genetic evidence of viral replication suggests that monitoring viral DNA during HAART may gauge low-level replication.
