Patients Undergoing Bariatric Surgery: a Special Risk Group for Lifestyle, Emotional and Behavioral Adaptations During the COVID-19 Lockdown. Lessons from the First Wave.

OBJECTIVES: To determine how the COVID-19 lockdown influenced the lifestyle, eating behavior, use of substances, mental health, and weight in patients who had undergone bariatric surgery (BS) and explore the self-perception of one's own health and fears related to COVID-19. METHODS: We performed a cross-sectional exploratory study in obesity patients who had undergone BS surgery > 1 year previously in a university hospital. Assessment was performed 40 days after initiating lockdown and included 2 periods: from April 24 until May 8 and during the initial de-escalation period: from May 9 until 22, 2020. A structured telephone interview and an online survey were administered. RESULTS: One hundred eighty-eight patients were interviewed; 156 also responded to the online survey (77% females, mean age 53.46 ± 10.48 years, mean follow-up 5.71 ± 4.30 years). Dietary habits were affected in 72% of the participants, with 15% reporting better diet planning; 83.5% reported having more sedentary behaviors; 27% and 36% showed depression and anxiety, respectively; and 45% of participants reported bad sleep quality. In relation to changes in the use of any substance, the use increased in the majority of patients who were previously users. Self-perception of one's own health and fears related to COVID-19 were only moderate. Finally, emotional eating and time since BS were statistically significant risk factors for predicting weight gain. CONCLUSIONS: Lockdown during COVID-19 pandemic negatively influenced the lifestyle, mental health, substance use, and weight in BS patients. These alterations were somewhat similar to those observed in the general population but more severe and with important clinical implications.

Substance use during pregnancy and personality dimensions. / Consumo de substancias durante el embarazo y dimensiones de personalidad.

Our aim was to assess personality traits associated with substance use during pregnancy in a population-based, multicentre study of 1804 pregnant women. On day 2-3 postpartum, participants completed a semi-structured interview, including self-reported drug use (alcohol, tobacco, caffeine, cannabis, cocaine, opioids) during pregnancy, and socio-demographic, reproductive and obstetric variables, personal and family psychiatric history, social support, and the Eysenck personality questionnaire, short version (EPQ-RS). Logistic regression models were conducted. Fifty per cent of women reported substance use during pregnancy: 40% caffeine, 21% tobacco, 3.5% alcohol, and 0.3 % cannabis. Mean T-scores (SD) for personality dimensions were 51.1 (9.6) for extraversion, 48 (8.9) for psychoticism, and 43.6 (8.5) for neuroticism. Extroversion (p = .029) and psychoticism (p = .009) were identified as risk factors after adjustment by age, level of education, employment status during pregnancy, low social support, and previous psychiatric history. For each increment of 10 units in their scores, the odds of substance use increased by 12% and 16% respectively. Low education, being on leave during pregnancy, and previous psychiatric history were independent factors (p < .05) associated with substance use during pregnancy. Primiparity was a protective factor (p = .001). The final models showed a good fit (p = .26). The screening of substance use during pregnancy should include personality dimensions apart from psychosocial variables and history of psychiatric disorders. It is important to identify the associated risk factors for substance use during pregnancy to prevent and improve foetal/neonatal and maternal health during perinatal period.

Este estudio evalúa los patrones de consumo de substancias durante el embarazo y las dimensiones de personalidad asociadas, en una muestra multicéntrica de 1804 mujeres de población general. En el 2-3 día posparto, completaron una entrevista auto-administrada sobre el consumo de alcohol, tabaco, cafeína, cannabis, cocaína, opiáceos, drogas de diseño, además de variables socio-demográficas, obstétricas/reproductivas, historia psiquiátrica previa, apoyo social durante el embarazo y el cuestionario de personalidad de Eysenck (EPQ-RS). Se generaron modelos de regresión logística múltiple. La prevalencia del consumo fue del 50% (N=909): 40% cafeína, 21% tabaco, 3,5% alcohol, y 0,3 cannabis. Las puntuaciones T medias (DE) de personalidad fueron: extraversión 51,1 (9,6), psicoticismo 48 (8,9) y neuroticismo 43,6 (8,5). Las dimensiones de extraversión (p=0,029) y psicoticismo (p=0,009), fueron identificadas como factores de riesgo tras ajustar por edad, nivel educación, estatus laboral durante el embarazo, bajo apoyo social, e historia psiquiátrica previa. Para cada incremento de 10 unidades en sus puntuaciones, el odds de consumo de substancias durante el embarazo se incrementó un 12% y un 16% respectivamente. Menor educación, estar de baja, y antecedentes psiquiátricos fueron también factores independientes (p<0,05) asociados al consumo. Ser primípara fue factor protector (p=0,001). El modelo final mostró un ajuste satisfactorio (p=0,26). El cribaje de las mujeres con riesgo de consumo de substancias durante el embarazo debería incluir la personalidad además de variables psicosociales y antecedentes psiquiátricos. Identificar los factores de riesgo asociados es importante para prevenir y mejorar la salud materna y fetal/neonatal durante el embarazo y posparto.

Incidence of depression in patients with hepatitis C treated with direct-acting antivirals

Objective: Depression has been associated with hepatitis C, as well as with its treatment with proinflammatory cytokines (i.e., interferon). The new direct-acting antiviral agents (DAAs) have minimal adverse effects and high potency, with a direct inhibitory effect on non-structural viral proteins. We studied the incidence and associated factors of depression in a real-life prospective cohort of chronic hepatitis C patients treated with the new DAAs. Methods: The sample was recruited from a cohort of 91 patients with hepatitis C, of both sexes, with advanced level of fibrosis and no HIV coinfection, consecutively enrolled during a 6-month period for DAA treatment; those euthymic at baseline (n=54) were selected. All were evaluated through the depression module of the Patient Health Questionnaire (PHQ-9-DSM-IV), at three time points: baseline, 4 weeks, and end-of-treatment. Results: The cumulative incidence (95%CI) of major depression and any depressive disorder during DAA treatment was 13% (6.4-24.4) and 46.3% (33.7-59.4), respectively. No differences were observed between those patients with and without cirrhosis or ribavirin treatment (p > 0.05). Risk factors for incident major depression during DAA treatment included family depression (relative risk 9.1 [1.62-51.1]), substance use disorder (11.0 [1.7-73.5]), and baseline PHQ-9 score (2.1 [1.1-3.1]). Conclusions: The findings of this study highlight the importance of screening for new depression among patients receiving new DAAs, and identify potential associated risk factors.

Coping strategies for postpartum depression: a multi-centric study of 1626 women.

The transition to motherhood is stressful as it requires several important changes in family dynamics, finances, and working life, along with physical and psychological adjustments. This study aimed at determining whether some forms of coping might predict postpartum depressive symptomatology. A total of 1626 pregnant women participated in a multi-centric longitudinal study. Different evaluations were performed 8 and 32 weeks after delivery. Depression was assessed using the Edinburgh Postnatal Depression Scale (EPDS) and the structured Diagnostic Interview for Genetic Studies (DIGS). The brief Coping Orientation for Problem Experiences (COPE) scale was used to measure coping strategies 2-3 days postpartum. Some coping strategies differentiate between women with and without postpartum depression. A logistic regression analysis was used to explore the relationships between the predictors of coping strategies and major depression (according to DSM-IV criteria). In this model, the predictor variables during the first 32 weeks were self-distraction (OR 1.18, 95 % CI 1.04-1.33), substance use (OR 0.58, 95 % CI 0.35-0.97), and self-blame (OR 1.18, 95 % CI 1.04-1.34). In healthy women with no psychiatric history, some passive coping strategies, both cognitive and behavioral, are predictors of depressive symptoms and postpartum depression and help differentiate between patients with and without depression.

A multidisciplinary support programme increases the efficiency of pegylated interferon alfa-2a and ribavirin in hepatitis C.

BACKGROUND & AIMS: Adherence to antiviral treatment is important to achieve sustained virological response (SVR) in chronic hepatitis C (CHC). We evaluated the efficiency of a multidisciplinary support programme (MSP), based on published HIV treatment experience, to increase patient adherence and the efficacy of pegylated interferon alfa-2a and ribavirin in CHC. METHODS: 447 patients receiving antiviral treatment were distributed into 3 groups: control group (2003-2004, n=147), MSP group (2005-2006, n=131), and MSP-validation group (2007-2009, n=169). The MSP group included two hepatologists, two nurses, one pharmacist, one psychologist, one administrative assistant, and one psychiatrist. Cost-effectiveness analysis was performed using a Markov model. RESULTS: Adherence and SVR rates were higher in the MSP (94.6% and 77.1%) and MSP-validation (91.7% and 74.6%) groups compared to controls (78.9% and 61.9%) (p<0.05 in all cases). SVR was higher in genotypes 1 or 4 followed by the MSP group vs. controls (67.7% vs. 48.9%, p=0.02) compared with genotypes 2 or 3 (87.7% vs. 81.4%, p=n.s.). The MSP was the main predictive factor of SVR in patients with genotype 1. The rate of adherence in patients with psychiatric disorders was higher in the MSP groups (n=95, 90.5%) compared to controls (n=28, 75.7%) (p=0.02). The cost per patient was € 13,319 in the MSP group and € 16,184 in the control group. The MSP group achieved more quality-adjusted life years (QALYs) (16.317 QALYs) than controls (15.814 QALYs) and was dominant in all genotypes. CONCLUSIONS: MSP improves patient compliance and increases the efficiency of antiviral treatment in CHC, being cost-effective.

Serotonin and interleukin-6: the role of genetic polymorphisms in IFN-induced neuropsychiatric symptoms.

BACKGROUND: Cytokines and serotonin neurotransmission may play an important role on the development of psychopathological symptoms during interferon (IFN) treatment. The aim of the present study was to investigate the association between IFN-induced depression, anxiety and fatigue and functional genetic variants at the interleukin-6 gene (IL-6) and serotonin transporter gene (SERT). METHODS: 385 consecutive Caucasian outpatients with chronic hepatitis C initiating treatment with IFN-alpha and ribavirin were included. All patients were interviewed at baseline using the Structured Clinical Interview for DSM-IV (SCID-I) and those with a current major depressive disorder or anxiety disorder before starting treatment were excluded. Depression and anxiety were assessed at baseline during the treatment (at 4, 12, 24 and 48 weeks) using the Hospital Anxiety and Depression Scale and fatigue was evaluated using a visual analogue scale. The 5-HTTLPR region of SERT gene and the functional polymorphism located at the promoter region of IL-6 gene (rs1800795) were genotyped. RESULTS: Genotypic distribution was in the Hardy-Weinberg equilibrium for SERT (p=0.41) and for IL-6 (p=0.72) polymorphisms. At baseline we found only a significant effect of IL-6 polymorphism on fatigue symptoms. During antiviral treatment we reported that subjects with CC genotype (IL-6) presented significantly lower changes from baseline in IFN-induced depression (p=0.005) and IFN-induced anxiety (p=0.004). We did not find statistically significant differences on depression (p=0.21) or anxiety (p=0.15) between SS/SL and LL genotypes of SERT. CONCLUSIONS: Genetic variations in the IL-6 gene increase the risk of IFN-induced depression and anxiety. The IL-6 polymorphism was associated with fatigue rates in patients with chronic hepatitis C before treatment. Our study confirms the role of inflammatory mechanisms in IFN-induced psychopathological symptoms.

Human microRNAs miR-22, miR-138-2, miR-148a, and miR-488 are associated with panic disorder and regulate several anxiety candidate genes and related pathways.

BACKGROUND: The involvement of microRNAs (miRNAs) in neuronal differentiation and synaptic plasticity suggests a role for miRNAs in psychiatric disorders; association analyses and functional approaches were used to evaluate the implication of miRNAs in the susceptibility for panic disorder. METHODS: Case-control studies for 712 single-nucleotide polymorphisms (SNPs) tagging 325 human miRNA regions were performed in 203 Spanish patients with panic disorder and 341 control subjects. A sample of 321 anxiety patients and 642 control subjects from Finland and 102 panic disorder patients and 829 control subjects from Estonia was used as a replica. Reporter-gene assays and miRNA overexpression experiments in neuroblastoma cells were used to functionally evaluate the spectrum of genes regulated by the associated miRNAs. RESULTS: Two SNPs associated with panic disorder: rs6502892 tagging miR-22 (p < .0002), and rs11763020 tagging miR-339 (p < .00008). Other SNPs tagging miR-138-2, miR-488, miR-491, and miR-148a regions associated with different panic disorder phenotypes. Replication in the north-European sample supported several of these associations, although they did not pass correction for multiple testing. Functional studies revealed that miR-138-2, miR-148a, and miR-488 repress (30%-60%) several candidate genes for panic disorder--GABRA6, CCKBR and POMC, respectively--and that miR-22 regulates four other candidate genes: BDNF, HTR2C, MAOA, and RGS2. Transcriptome analysis of neuroblastoma cells transfected with miR-22 and miR-488 showed altered expression of a subset of predicted target genes for these miRNAs and of genes that might be affecting physiological pathways related to anxiety. CONCLUSIONS: This work represents the first report of a possible implication of miRNAs in the etiology of panic disorder.

Depression in hospitalized patients with malignant melanoma treated with interferon-alpha-2b: primary to induced disorders.

Our objective was to study the clinical and management differences between primary and interferon (IFN)-induced depressive disorders in malignant melanoma patients visited by the consultation-liaison team during a two year period. This was a prospective study of 31 patients with malignant melanoma treated with IFN-alpha in a general teaching hospital. Clinical, psychiatric variables and DSM-IV-TR diagnosis were analyzed. The Clinical Global Impression Severity (CGI-S) and Improvement (CGI-I) of illness scales were administered at the time of consultation and at the end of hospitalization. The main diagnoses were depressive adjustment disorders in 14 patients (45.16%) followed by interferon-induced depressive disorders in 6 (19.36%). In patients with adjustment disorders, melanoma stage was significantly more advanced than in those with interferon-induced depressive disorder (p = 0.019). The latter scored higher in the CGI-S scale (p = 0.044) and in the CGI-I scale (p = 0.029). The interferon-induced depressive disorders, except one who required a reduction of IFN-alpha-2b dose, were successfully treated with antidepressant drugs. Clinical management and antidepressant treatment allowed the continuation of interferon therapy in malignant melanoma patients. Interferon-induced depression occurred in a few patients, which in turn were the most severe. Adjustment depressive disorder was the most common psychiatric diagnosis.

Utilization of psychiatric emergency services by homeless persons in Spain.

OBJECTIVE: Studies examining the relationship between homeless persons and the use of psychiatric emergency services (PES) in a country with universal access to health care are lacking. This study aimed to determine the prevalence of homelessness in adults visiting a PES in Spain, identify the differences between homeless and non-homeless patients in the use of PES and analyze the factors associated with homelessness and the decision to hospitalize. METHOD: The study included a total of 11 578 consecutive admissions to a PES in a tertiary hospital in Barcelona, Spain, over a 4-year period. Data collected included socio-demographic and clinical information, and score on the Severity of Psychiatric Illness (SPI) scale. Multivariate logistic regression analyses were used to calculate odds ratios for the factors associated with homelessness and the decision to hospitalize. RESULTS: Five hundred sixty (4.8%) admissions were considered homeless. Homeless patients had more psychotic and drug abuse disorders, greater severity of symptoms, more risk of being a danger to others and more frequent hospitalization needs than non-homeless patients. Factors related to homelessness were male gender, substance abuse and immigrant status from North Africa, Sub-Sahara Africa and Western countries. The decision to hospitalize homeless patients was associated with psychosis diagnosis, suicide risk, danger to others, symptom severity, medical problems and noncompliance with treatment. CONCLUSIONS: In an attempt to decrease the use of emergency resources and prevent the risk of homelessness, mental health planners in a universal healthcare system should improve outpatient access for populations with risk factors such as substance abuse and immigration.

Decrease of the platelet 5-HT2A receptor function by long-term imipramine treatment in endogenous depression.

BACKGROUND: Animal studies have found that many antidepressants induce decreases in both the density and the functional activity of the serotonin 2A (5-HT2A) receptor subtype. However, the extrapolation of findings to humans has been inconclusive. A physiological platelet response mediated by this receptor, the serotonin-amplified platelet aggregation, was measured to study whether long-term antidepressant treatment induces changes in 5-HT2A receptor functioning in endogenous depressed patients. METHOD: The percentage of serotonin-amplified platelet aggregation to adenosine diphosphate (ADP) was studied in 15 untreated patients with major depressive disorder (DSM-IV) with endogenous features (Newcastle scale). This index was used as an indirect measurement of the functional status of platelet 5-HT2A receptors. Aggregation studies were repeated once remission of the symptoms was achieved during treatment with imipramine (150-300 mg/day). A group of 15 concurrent normal subjects was used as a control. RESULTS: A statistically significant decrease (p = 0.038) in the percentage of serotonin-amplified platelet aggregation to ADP was observed when remission was achieved (after 145 +/- 27 days). CONCLUSIONS: The results showed a decrease in a platelet functional response mediated by 5-HT2A receptors following effective imipramine treatment, suggesting that desensitization or down-regulation of the 5-HT2A receptor function could be linked to the therapeutic effect of some antidepressants. The data also support the use of platelet aggregometry as a surrogate measurement of antidepressant action, particularly in intra-subject designs.
