RESUMO
BACKGROUND: Ketamine has been documented for its rapid antidepressant effects. However, optimal dose and delivery route have not yet been thoroughly investigated. The objectives of this study were to document the safety and test the antidepressant and antisuicidal effects of a single rapid 1-minute injection of ketamine 0.5 mg/kg in treatment-resistant depression (TRD). METHODS: Ten patients with TRD were included in an open, noncontrolled 4-week study and received a rapid intravenous dose of ketamine 0.5 mg/kg. Main outcome measure was the Montgomery-Åsberg Depression Rating Scale and suicidality was assessed using the Scale for Suicide Ideation. RESULTS: Rapid injection of ketamine elicited transient increase of blood pressure and altered states of consciousness in all patients and mild psychotomimetic effects in 4 patients, which all resolved without any intervention. Decrease of depression severity was observed from 40-minute postinjection until day 15. Eight patients became responders within 1 day and all were nonresponders after 4 weeks. The decrease of suicidal ideation was significant until day 7. Analysis indicated that higher severity of depression and anxiety at baseline predicted a larger Montgomery-Åsberg Depression Rating Scale decrease after 4 weeks. CONCLUSIONS: This study suggests that in well-controlled medical settings with adequate monitoring, a single rapid 1-minute injection of ketamine 0.5 mg/kg can be well tolerated and is efficacious in rapidly reducing depression symptoms and suicidal thoughts in outpatients with TRD. These findings are relevant to the practice of general clinical psychiatry and emergency departments were ketamine can have a place in acute management of TRD. Larger studies are necessary to confirm these results.

Racing thoughts refer to an acceleration and overproduction of thoughts, which have been associated with manic and mixed episodes. Phenomenology distinguishes 'crowded' from 'racing' thoughts, associated with mixed depression and mania, respectively. Recent data suggest racing thoughts might also be present in healthy individuals with sub-affective traits and symptoms. We investigated this assumption, with a 34-item self-rating scale, the Racing and Crowded Thoughts Questionnaire (RCTQ), and evaluated its reliability, factor structure, and concurrent validity. 197 healthy individuals completed the RCTQ, the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego - autoquestionnaire (TEMPS-A), the Beck Depression Inventory (BDI), the Altman Self-Rating Mania scale (ASRM), and the Ruminative Response Scale (RRS). Exploratory factor analysis yielded a three-factor solution, labeled 'thought overactivation', 'burden of thought overactivation', and 'thought overexcitability'. Internal consistency of each of the three subscales of the RCTQ was excellent. The TEMPS-A cyclothymia score was associated with the three factors, suggesting good concurrent validity. The 'thought activation' subscale was selectively associated with current elated mood and included items conveying both the notion of increased amount and velocity of thoughts, whereas the 'burden of thought overactivation' subscale was associated with current low mood. The 'thought overexcitability' subscale included items conveying the notion of distractibility, and was associated with both elated and low mood. Rumination was not a significant predictor of RCTQ subscores. These results suggest that the RCTQ has good psychometric properties. Racing and crowded thoughts, as measured by the RCTQ, are a multi-faceted phenomenon, distinct from rumination, and particularly associated with mood instability even in its milder forms.

A high prevalence of mental illness has been reported in asylum seekers. The present cross-sectional study examined suicidal thoughts, treatment modalities (outpatient crisis intervention, inpatient care), and their determinants in asylum seekers (n = 119) and permanent residents (n = 120) attending the same outpatient clinic in Geneva, Switzerland. The most frequent diagnoses were depressive disorders (64.7%) and posttraumatic stress disorder (34.5%) in asylum seekers and psychotic (55.0%) and depressive disorders (33.3%) in permanent residents. The frequency of suicidal thoughts was similar in both groups (>30%). Asylum seekers benefited from outpatient crisis intervention more frequently than residents did (26.9% vs. 5.8%), whereas inpatient care was less frequent (25.2% vs. 44.2%). In asylum seekers, acute suicidal thoughts were associated with increased frequency of outpatient crisis interventions, and, suicidal thoughts, psychosis, or personality disorders were associated with higher rates of hospitalization. Documenting clinical characteristics and service utilization of asylum seekers is a prerequisite to organizing targeted interventions.

OBJECTIVES: This retrospective study aimed to assess to what extent an adverse drug reaction (ADR), an abnormal therapeutic drug monitoring (TDM) or a non-response, was attributable to an abnormal cytochrome P450 activity in a psychiatric setting. METHOD: We collected the results of investigations performed in these situations related to psychotropic drugs between January 2005 and November 2014. Activities of different cytochrome P450 were assessed by genotyping and/or phenotyping. Two experienced clinical pharmacologists assessed independently the possible association between the event and the results of the investigations. RESULTS: One hundred and thirty eight clinical or biological situations had a complete assessment of all major metabolic pathways of the target drug. A majority of clinical or biological situations were observed with antidepressants (n=93, 67.4%), followed by antipsychotics (n=28, 20.3%), benzodiazepines and hypnotics (n=13, 9.4%), and psychostimulants (n=4, 2.9%). Genotype and/or phenotype determination was mainly performed because of ADRs (n=68, 49.3%) or non-response (n=46, 33.3%). Inter-rate reliability of the scoring system between the pharmacologists was excellent (kappa=0.94). The probability of an association between ADR, TDM or non-response and metabolic status was rated as intermediate to high in 34.7% of all cases, with proportions of 30.4% and 36.7%, for non-response and ADR respectively. CONCLUSION: When indicated by clinical pharmacologists, ADR, TDM or non-response may be attributable to a variation of the metabolic status with an intermediate to high probability in 34.7% of patients, based on the congruent assessment made by two clinical pharmacologists. Further studies assessing the clinical relevance of prospective explorations and clarifying the appropriate method according to the clinical context are needed.

Psychoeducation is a key element in the management of patients with bipolar disorders. The present study explored the perception of patients and family members with respect to group psychoeducation for relatives. Patients (n = 20) and relatives (n = 26) were assessed with questionnaires about perceived benefits and quality of life (median 4 years after participation). A large majority (>80%) of relatives acknowledged benefits with respect to easier detection of the early warning signs of relapse, improved quality of life, feeling more involved, and engaging in higher quality caregiving activities. Patients were less positive in general, but agreed that the program had helped them deal with crises, increased their feeling of being understood by relatives, and promoted positive changes in the family (>60%). Perceived positive changes in the family were associated with higher quality of life for relatives and patients. The present study highlights the importance of communication enhancement in group psychoeducation for relatives.

Maternal interpersonal violence-related post-traumatic stress disorder (IPV-PTSD) is known to be associated with impairment of a mother's capacity to participate in mutual emotion regulation during her child's first years of life. This study tested the hypothesis that maternal difficulty in identifying feelings in self and other, as an important dimension of the construct of alexithymia, together with maternal IPV-PTSD, would be negatively associated with maternal sensitivity. Maternal sensitivity to child emotional communication is a marker of maternal capacity to engage in mutual regulation of emotion and arousal. Following diagnostic interviews and administration of the Toronto Alexithymia Scale, 56 mothers and their toddlers (ages 12-42 months) were filmed during free-play and separation/novelty-exposure. Observed maternal sensitivity was coded via the CARE-Index. Maternal IPV-PTSD severity, difficulty in identifying emotions, and lower socio-economic status were all associated with less maternal sensitivity, and also with more maternal controlling and unresponsive behavior on the CARE-Index.

BACKGROUND: Racing thoughts, crowded thoughts and flight of ideas are frequent symptoms in mood disorders, but the underlying subjective experience of overactivation of thought processes remains poorly documented. METHODS: Qualitative analysis of audiotaped interviews explored subjective experience of thought overactivation in patients with mood disorders (sample 1, n = 45). Quantitative analysis considered the properties of a newly developed rating scale in sample 1, in an additional sample of patients with mood disorders (sample 2, n = 37) and in healthy subjects (sample 3, n = 38). RESULTS: Qualitative analysis of individual interviews revealed that 5 conceptual categories characterized thought overactivation: sequential thought flow, overstimulation, competition for resource allocation, unexpected/unexplained onset, and association with mood and emotions. A principal component analysis of the initial 16-item rating scale indicated that a single component explained 55.9% of the variance, with major and exclusive contributions from 9 items, which were retained in the final 9-item Subjective Thought Overactivation Questionnaire (STOQ; Cronbach's α = 0.95). Total score correlated significantly with activation, depression and perceived conflict subscales of the Internal State Scale (ISS; rs = 0.57-0.66, p < 0.001). It was associated with decreased well-being (ISS; rs = -0.48, p = 0.001) and increased state anxiety (State-Trait Anxiety Inventory; rs = 0.60, p < 0.001). The STOQ score was significantly higher in patients than in healthy subjects. It allowed distinguishing between ISS mood states, with the highest median score in mixed states. LIMITATIONS: Sample size, representativeness, possible bias in qualitative analysis, and quality of expert consensus. CONCLUSIONS: Qualitative analysis of clinical interviews, together with a new short rating scale, contributed to a documentation of subjective thought overactivation, an important but often undetected feature in mood disorders.

OBJECTIVES: We developed a population model that describes the ocular penetration and pharmacokinetics of penciclovir in human aqueous humour and plasma after oral administration of famciclovir. METHODS: Fifty-three patients undergoing cataract surgery received a single oral dose of 500 mg of famciclovir prior to surgery. Concentrations of penciclovir in both plasma and aqueous humour were measured by HPLC with fluorescence detection. Concentrations in plasma and aqueous humour were fitted using a two-compartment model (NONMEM software). Inter-individual and intra-individual variabilities were quantified and the influence of demographics and physiopathological and environmental variables on penciclovir pharmacokinetics was explored. RESULTS: Drug concentrations were fitted using a two-compartment, open model with first-order transfer rates between plasma and aqueous humour compartments. Among tested covariates, creatinine clearance, co-intake of angiotensin-converting enzyme inhibitors and body weight significantly influenced penciclovir pharmacokinetics. Plasma clearance was 22.8±9.1 L/h and clearance from the aqueous humour was 8.2×10(-5) L/h. AUCs were 25.4±10.2 and 6.6±1.8 µg·h/mL in plasma and aqueous humour, respectively, yielding a penetration ratio of 0.28±0.06. Simulated concentrations in the aqueous humour after administration of 500 mg of famciclovir three times daily were in the range of values required for 50% growth inhibition of non-resistant strains of the herpes zoster virus family. CONCLUSIONS: Plasma and aqueous penciclovir concentrations showed significant variability that could only be partially explained by renal function, body weight and comedication. Concentrations in the aqueous humour were much lower than in plasma, suggesting that factors in the blood-aqueous humour barrier might prevent its ocular penetration or that redistribution occurs in other ocular compartments.

Temperament is considered as a biological disposition reflected by relatively stable features related to mood and reactivity to external and internal stimuli, including variability in emotional reactions. The aim of the present study is to test the hypothesis that affective temperaments might differ according to co-occurring mood disorders among patients with alcohol and/or opiate dependence; to explore the relationship between temperaments and dual substance use disorders (SUDs, alcohol and other drugs). Ninety-two patients attending an alcohol addiction treatment facility and 47 patients in an opiate addiction treatment facility were assessed for SUDs, mood disorders and affective temperaments using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego 39-item auto-questionnaire. Comparison of patients with bipolar disorder, depressive unipolar disorder and no (or substance-induced) mood disorder revealed significant differences for the cyclothymic subscale, with highest scores among patients with bipolar disorder. No difference was observed for the depressive, irritable, hyperthymic and anxious subscales. After adjustment for age, gender and bipolar disorder, irritable temperament was a significant risk factor for past or present history of drug use disorders in patients treated for alcohol addiction (odds ratio [OR] 1.42, 95% confidence interval [CI] 1.05-1.93). Anxious temperament was a significant risk factor for history of alcohol use disorders in patients treated for opiate addiction (OR 3.30, 95% CI 1.36-7.99), whereas the hyperthymic subscale appeared as a significant protective factor (OR 0.65, 95% CI 0.42-0.99). The results highlight the need to consider temperamental aspects in further research to improve the long-term outcome of patient with addictive disorders, who often present complex comorbidity patterns.

BACKGROUND: The aim of the present study was to examine the use of health-care services and medication, as well as health risk behaviours such as smoking, in relation with post-traumatic stress disorder (PTSD) and major depressive episode (MDE) in post-war Kosovo. METHODS: A sample of 864 adults was interviewed in 2007 of which 551 took part in a 2001 survey. They were assessed using the PTSD and MDE sections of the Mini International Neuropsychiatric Interview (MINI) and the Medical Outcomes Study 36-item Short Form Health Survey (SF-36). Use of health-care services, alcohol and tobacco were also recorded. RESULTS: Respondents were predominantly female (56.6%) with a median age of 36 years and a primary educational level (44.6%). While 11.9% of participants met diagnostic criteria for PTSD, MDE prevalence was 30.6%. Both PTSD and MDE were significantly associated with lower scores on the SF-36 physical component summary. After adjustment for sex, age, education, unemployment, municipality and SF-36 perceived physical health, no significant association was observed between PTSD and medical visits in the past 12 months, hospitalizations in the past 12 months and use of medication in the past 7 days. Results were similar for MDE, except for a significantly higher frequency of medication use that included psychotropic and other drug classes. CONCLUSION: Eight years after the war in Kosovo, poor perceived physical health displayed a long-lasting association with PTSD and MDE and was a major determinant of increased use of health-care services without additional contribution of PTSD per se.

PURPOSE: To examine the socio-demographic determinants of post-traumatic stress disorder (PTSD) and its association with major depressive episode and self-perceived physical and mental health in a large random sample of the Rwandan population 14 years after the 1994 genocide. METHODS: Using the Mini International Neuropsychiatric Interview and Medical Outcomes Study 36-Item Short-Form (SF-36) translated in Kinyarwanda, we interviewed 1,000 adult residents from the five provinces of Rwanda. Socio-demographic data and specific somatic symptoms were also recorded. Data analysis included 962 questionnaires. RESULTS: Participants were predominantly female (58.9%), aged between 16 and 34 years (53.2%), with a low level of education (79.7% below secondary school). Prevalence of PTSD was estimated to be 26.1%. In multivariable analysis, factors associated with PTSD were being aged between 25 and 34 years, living in extreme poverty, having endured the murder of a close relative in 1994, being widowed or remarried, having lost both parents and living in the South Province. Participants who fulfilled diagnostic criteria for PTSD were significantly more often affected with major depression (68.4 vs. 6.6%, P < 0.001) and substance dependence (7.6 vs. 3.5%, P = 0.013) than respondents without PTSD. They scored significantly lower on all SF-36 subscales. Somatic symptoms such as hiccups, fainting and loss of speech or hearing delineated a specific pattern of post-traumatic stress syndrome. CONCLUSIONS: PTSD remains a significant public health problem in Rwanda 14 years after the genocide. Facilitating access to appropriate care for all those who need it should be a national priority.

PURPOSE: Long-term outcome of traumatic experiences among war-exposed civilians living in their home country has been seldom documented. The present study examined change in posttraumatic stress disorder (PTSD) frequency and perceived physical and mental health in a cohort of Kosovar Albanians over 6 years (2001-2007). METHODS: Of 996 Albanian Kosovar civilians included in the 2001 survey, 551 subjects (55.3%) were recalled and interviewed in 2007. Diagnoses of PTSD and major depressive episode were assessed using the Mini International Neuropsychiatric Interview. Subjective physical and mental health were investigated using the Medical Outcomes Study 36-Item Short-Form (SF-36). A list of traumatic events adapted from the Harvard Trauma Questionnaire and other stressful life events was also considered. RESULTS: Posttraumatic stress disorder was significantly less frequent in 2007 than in 2001 (14.5% vs. 23.2%, p < 0.001). For 18.0, 5.3 and 9.3% of participants, PTSD remitted, persisted and developed over the 6-year follow-up period, respectively. Ill health without having access to medical care and major changes in responsibilities at work were associated with both persistence and new occurrence of PTSD. While the SF-36 mental component summary score significantly improved (mean change +4.5, p < 0.001), the physical component summary score did not change between 2001 and 2007, after adjustment for age (mean change -0.8, p = 0.14). CONCLUSIONS: Results point at the importance of economic and health system reconstruction programs with respect to public health in post-conflict countries.

PURPOSE: Vogt-Koyanagi-Harada (VKH) disease and sympathetic ophthalmia (SO) are two distinct entities that share common clinical and histopathological features; however, it remains unknown whether they have a common genetic susceptibility. Several studies have shown an association of human leukocyte antigen (HLA)-DR4 with VKH disease in patients of different ethnic backgrounds. We present in this paper the HLA-DRB1 genotyping analysis of a large cohort of VKH patients from southern India and compare these patients to patients with SO and to healthy individuals from the same geographic area. METHODS: VKH patients were diagnosed according to the revised criteria of the International Committee on VKH disease. Patients with granulomatous uveitis after ocular trauma or multiple eye surgeries were diagnosed as having SO. Genomic DNA was extracted from all patients and controls. Samples were analyzed for HLA-DRB1 alleles by reverse polymerase chain reaction (PCR) sequence-specific oligonucleotide (SSO) hybridization on microbeads, using the Luminex technology, and by PCR sequence-specific primers (SSP) typing for DRB1*04 allele determination. Strength of associations was estimated by odds ratios (OR) and 95% confidence intervals (CI) and frequencies were compared using the Fisher's exact test. RESULTS: HLA-DRB1 alleles were determined in 94 VKH patients, 39 SO patients, and 112 healthy controls. HLA-DRB1*04 frequency was higher in VKH patients (20.2% versus 10.3% in controls; OR=2.2, p=0.005, pc=0.067). This association was lower than the association of HLA-DRB1*04 frequency in cohorts of patients from different origins. No significant DR4 association with SO was detected. HLA-DRB1*0405 and HLA-DRB1*0410 alleles were significantly increased in VKH patients (8.5% versus 0.9% in controls; OR=10.3, 95% CI=2.34-45.5, p<0.001). These two alleles share the epitope S57-LLEQRRAA (67-74) in the third hypervariable region of the HLA-DR molecule. None of the DRB1 alleles was significantly associated with SO. CONCLUSIONS: Based on the association of HLA-DRB1*0405 and HLA-DRB1*0410 alleles with VKH disease, we propose that the epitope S57-LLEQRRAA (67-74) in the third hypervariable region of the HLA-DRbeta1 molecule is the relevant susceptibility epitope. This genetic component seems specific to VKH disease since no correlation could be identified in SO patients. The weaker association with HLA-DR4 in this VKH patient cohort compared to VKH patients from northern India is probably related to the lower frequency of HLA-DRB1*0405 in our study group. The HLA-DRB1 association with susceptibility to VKH syndrome seems weaker in Indian patients compared to Japanese or Hispanic patients, suggesting a different non-HLA immunogenetic background in Indian VKH patients.

BACKGROUND: The article addresses the hypothesis that early telephone intervention for psychiatric outpatients starting antidepressant treatment would increase compliance with pharmacological treatment and retention time in the study, and thus allow for a more favourable clinical outcome. METHODS: The study focuses on 131 depressed outpatients who participated in a study aiming to obtain full remission. Patients who benefited from three early structured telephone interventions (n=81) were compared with participants who benefited from the usual care (n=50) with no clinical contact before the first clinical assessment at 2 weeks. RESULTS: The intervention proved to have no significant effect on treatment adherence, attrition rate, exclusion rate for adverse events or improvement of depression severity. It was nevertheless associated with increased retention time in the present study. CONCLUSIONS: These results suggest that motivational phone calls may reinforce adhesion in psychiatric patients and provide early opportunities to adapt treatment to individual needs. CLINICAL IMPLICATION: These results suggest that motivational phone calls may reinforce adhesion in psychiatric patients and provide early opportunities to adapt treatment to individual needs.

This retrospective study evaluates the link between an adverse drug reaction (ADR) or a non-response to treatment and cytochromes P450 (CYP), P-glycoprotein (P-gp) or catechol-O-methyltransferase (COMT) activity in patients taking analgesic drugs for chronic pain. Patients referred to a pain center for an ADR or a non-response to an analgesic drug between January 2005 and November 2014 were included. The genotype and/or phenotype was obtained for assessment of the CYPs, P-gp or COMT activities. The relation between the event and the result of the genotype and/or phenotype was evaluated using a semi-quantitative scale. Our analysis included 243 individual genotypic and/or phenotypic explorations. Genotypes/phenotypes were mainly assessed because of an ADR (n = 145, 59.7%), and the majority of clinical situations were observed with prodrug opioids (n = 148, 60.9%). The probability of a link between an ADR or a non-response and the genotypic/phenotypic status of the patient was evaluated as intermediate to high in 40% and 28.2% of all cases, respectively. The drugs in which the probability of an association was the strongest were the prodrug opioids, with an intermediate to high link in 45.6% of the cases for occurrence of ADRs and 36.0% of the cases for non-response. This study shows that the genotypic and phenotypic approach is useful to understand ADRs or therapeutic resistance to a usual therapeutic dosage, and can be part of the evaluation of chronic pain patients.
RESUMO
AIM: American and European associations of cardiology published specific guidelines about recommended drugs for secondary prevention in ST-segment elevation myocardial infarction (STEMI) patients. Our aim was to assess whether drug prescription for STEMI patients was in accordance with the guidelines at discharge and after 1 year. METHOD: We used data of 361 patients admitted for STEMI in a tertiary hospital in Switzerland from 2014 to 2016. We assessed the adequacy of prescription of recommended drugs at two time points: discharge and after 1 year. Medications assessed were aspirin, P2Y12 inhibitors, statin, angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) and ß-blockers. We took into account several criteria like statin dosage (low versus high intensity) and presence of contraindication for consideration of optimal therapy. Predictors of incomplete prescription of guideline medications were then assessed with multivariate logistic regression models. RESULTS: From discharge (n = 358) to 1-year follow-up (n = 303), rate of optimal prescription was reduced from 98.6 to 91.7% for aspirin, from 93.9 to 79.1% for P2Y12 inhibitors, from 83.8 to 65.7% for statins, from 98.6 to 95.6% for ACEIs/ARBs, and from 97.1 to 96.9% for ß-blockers. Predictors of incomplete prescription of guideline medications at discharge were female sex (odds ratio [OR] 2.54, p = 0.007), active or former smoker status (OR 2.29, p = 0.017), multivessel disease (OR 2.07, p = 0.022), left ventricular ejection fraction < 40% (OR 2.49, p = 0.008), and transfer to cardiac surgery (OR 9.66, p = 0.018). At 1 year, age > 65 (OR 1.92, p = 0.036) remained the only significant predictor. CONCLUSION: The present study showed a high prescription rate of guideline-recommended medications in a referral center for primary percutaneous coronary intervention. At discharge, women and co-morbid patients were at the highest risk of incomplete prescription of guideline medications, whereas long-term prescription was suboptimal for elderly. A drug lacking at time of discharge was rarely introduced within the year, which underscores the paramount importance of optimal prescription at time of discharge. Strategies like implementing a standardized prescription could reduce the proportion of suboptimal prescription. It could therefore be one way to improve the long-term quality of care of our patients to the highest level. This study used local data from AMIS Plus-National Registry of Acute Myocardial Infarction in Switzerland (NCT01305785).

BACKGROUND: Sub-clinical symptoms of psychosis such as hallucinations and delusions, known as positive schizotypy, constitute one of the strongest predictive factors for adult psychotic disorders. Recent cognitive models suggest that the expression of positive schizotypy is associated with depression, anxiety, metacognitive beliefs and self-monitoring deficits. In this study, we present empirical data on the relationships positive schizotypy hold with both emotional and cognitive factors. METHODS: A sample of 163 adolescents (77 females) participated in this study (mean age 15.3, 12-18 years). Subjects filled out self-report questionnaires assessing the emotional dimensions of depression and anxiety, as well as metacognitive beliefs. Self-monitoring skills were assessed using an action monitoring paradigm sensitive to dysfunctions associated with psychosis-proneness. Multivariate regression models were employed to examine emotional and cognitive contributions to positive schizotypy during adolescence. RESULTS: Analyses revealed that dimensions of depression, anxiety, and metacognitive beliefs significantly correlated with the expression of positive schizotypy. When accounting for the effects of depression and metacognitive beliefs in adolescents reporting hallucinations, self-monitoring dysfunctions seemed to represent a significant factor in the expression of positive schizotypy. CONCLUSION: The present results suggest that the expression of positive schizotypy during adolescence is modulated by emotional factors of depression and anxiety, as well as metacognitive beliefs and self-monitoring dysfunctions. The current data lend some evidence that supports the cognitive-developmental account of positive symptom formation before the onset of a psychotic disorder.

BACKGROUND: There are virtually no reported experiences of mixed medical/psychiatry inpatient units in Europe. Such a program was created in Geneva, Switzerland, in 1999. OBJECTIVE: The authors retrospectively analyzed clinical data from its first 5 years of operation. METHOD: These data represent 1,380 hospitalizations. A descriptive analysis was carried out on all collected data for each year of activity. RESULTS: The severity of physical disorders increased with time. The number of medical comorbidities, length of hospital stay, and compulsory admissions increased. The proportion of mood disorders decreased, whereas the proportion of psychotic and adjustment disorders increased. CONCLUSION: Patients with comorbid medical and psychiatric disorders are often refused admission to both medical and psychiatric wards. Once they are admitted, they are often released prematurely or transferred to another ward too quickly because of behavioral management difficulties. Physicians who refer patients to the unit recognize the complex nature of these cases and refer them because the unit is capable of offering acute psychiatric and medical treatments and provides an environment that encourages patient cooperation and treatment adherence.

OBJECTIVE: To evaluate the performance of the French version of the Mood Disorder Questionnaire (MDQ) in patients attending a general psychiatric outpatient service as well as whether MDQ scores are independent of patient mood state at time of completion. METHOD: 183 patients completed the MDQ and were assessed with the MADRS and YMRS scales, before being interviewed with the SCID (time 1). MDQ, MADRS and YMRS assessment was repeated four to six weeks later (time 2). RESULTS: According to the SCID, 44 patients were suffering from bipolar spectrum disorder and 102 from unipolar disorder (37 patients dropped out). The MDQ provided high specificity (83.3%). Sensitivity was 63.6%, with better identification of bipolar I (85.0%) than bipolar II patients (45.8%). In the whole sample, test-retest reliability was satisfactory (kappa=0.64). Modest correlations were observed between the number of endorsed MDQ items and YMRS scores at time 1 (Spearman r=0.19; p=0.021) and time 2 (r=0.26; p=0.002). CONCLUSIONS: Despite some fluctuations over time and a discrete influence of symptom severity, the screening algorithm can be used reliably, whether in the acute or remission phase of a depressive episode.

INTRODUCTION: In psychiatric patients, tobacco withdrawal symptoms are frequently seen as a barrier to smoking cessation; however, further studies are warranted in this specific population. METHODS: Patients receiving in- or out-patient mental health care participated in a motivational enhancement program including a 26-hour tobacco abstinence experience with professional support and optional nicotine replacement therapy. The study included 174 subjects, of whom 159 were evaluated 1 week before and at the end of the 26-hour abstinence period. Repeated assessments included the Minnesota Nicotine Tobacco Withdrawal Scale Revised (MNWS-R), two items of the Mood and Physical Symptoms Scale (MPSS) regarding craving, the State-Trait Anxiety Inventory (STAI-S), the Beck Depression Inventory (BDI-21), and the World Health Organization Well-Being Index (WHO-5). RESULTS: More than half the participants (52.3%) succeeded in 26-hour smoking abstinence. Craving was the most frequent MNWS-R withdrawal symptom (28.3% scored ≥3 on a 0-4 scale). Comparison of pre- and post-intervention data revealed significant improvements in 13 of 16 MNWS-R symptoms as well as craving (MPSS) and well-being, and significant decreases in anxiety and depression. Increasing MNWS-R craving scores and greater depression were both significantly associated with lower success in the 26-hour smoking abstinence period. CONCLUSIONS: The negative effects of tobacco withdrawal symptoms in psychiatric patients may be substantially overestimated. Participation in a supportive structured motivational intervention with a 26-hour smoking cessation experience was well tolerated and contributed to temporary improvements in mental state. Craving is an interesting symptom to evaluate during smoking cessation attempts.
