Prevalence of psychiatric symptoms and associated factors in the adult population from the area affected by the tailings dam rupture – Brumadinho Health Project. REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2022; 25:e220011. [DOI: 10.1590/1980-549720220011.supl.2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 09/05/2022] [Indexed: 11/07/2022] Open
Abstract
ABSTRACT: Objective: To examine the prevalence of psychiatric symptoms and associated factors in the adult population of Brumadinho (MG), after the dam collapse. Methods: We included 2,740 participants with information about symptoms of post-traumatic stress disorder (PTSD), depression, anxiety, thoughts of death/self-harm, and poor sleep quality collected in 2021. Prevalence values of all conditions were estimated to compare the prevalence of psychiatric symptoms with the participants’ sociodemographic characteristics and place of residence. Pearson’s c2 test was used, with Rao Scott’s correction. Crude and adjusted logistic regressions estimated odds ratios and 95% confidence intervals to assess the association between psychiatric symptoms and participants’ characteristics. Results: The most common condition was depressive symptoms (29.3%), followed by post-traumatic stress symptoms (22.9%) and anxious symptoms (18.9%). Regarding the association between participants’ characteristics in the adjusted analysis, being a female and living in a mining area was positively associated with symptoms of PTSD, depression, anxiety, thoughts of death/self-harm, and poor sleep quality. A positive association was also found between high school education and post-traumatic stress symptoms. In contrast a negative association was found between being aged ≥60 years and symptoms of PTSD, depression, and anxiety. Conclusion: High prevalence values were found for all psychiatric symptoms after the dam failure in Brumadinho. Being a female, living in the mining area, being ≥60 years old, and having an educational level were all associated with the psychiatric symptoms investigated.

Abstract
RESUMO: Objetivo: Examinar a prevalência dos sintomas psiquiátricos e seus fatores associados na população adulta de Brumadinho (MG), após o rompimento da barragem. Métodos: Foram incluídos 2.740 participantes com informações coletadas em 2021 sobre os sintomas de estresse pós-traumático (TEPT), depressão, ansiedade, ideias de morte/automutilação e pior qualidade do sono. Estimaram-se as prevalências de todas as condições. Para a comparação das prevalências dos sintomas psiquiátricos e as características sociodemográficas e local de moradia, empregou-se o teste χ2 de Pearson, com correção de Rao-Scott. Regressões logísticas brutas e ajustadas estimaram os odds ratios e intervalos de confiança de 95%, permitindo a avaliação da associação entre os sintomas psiquiátricos e as características dos participantes. Resultados: Os sintomas depressivos foram a condição mais prevalente (29,3%), seguidos pelos sintomas de TEPT (22,9%) e sintomas ansiosos (18,9%). Com relação à investigação da associação entre as características dos participantes na análise ajustada, observou-se que o sexo feminino e os moradores da área de mineração apresentaram relação positiva com os sintomas de TEPT, depressivos, ansiosos, ideia de morte e pior qualidade de sono. Também se encontraram associação positiva entre a escolaridade de nível médio e os sintomas de TEPT e associação negativa entre aqueles com ≥60 anos e os sintomas de TEPT, depressivos e ansiosos. Conclusão: Altas prevalências foram encontradas para todos os sintomas psiquiátricos após a ruptura da barragem em Brumadinho. Sexo feminino, local de moradia na área de mineração, ≥60 anos e escolaridade foram associados aos sintomas psiquiátricos investigados.

The GNE-KLH anti-cocaine vaccine protects dams and offspring from cocaine-induced effects during the prenatal and lactating periods. Mol Psychiatry 2021; 26:7784-7791. [PMID: 34381172 DOI: 10.1038/s41380-021-01210-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 06/03/2021] [Accepted: 06/23/2021] [Indexed: 02/07/2023]
Abstract
Protecting children from prenatal cocaine exposure is a significant challenge for physicians and childbearing women with cocaine use disorder. Cocaine use is highly prevalent among reproductive-aged women and prenatal cocaine exposure produces obstetric, foetal neurodevelopmental and long-term behavioural impairments. Cocaine crosses the maternal and foetal blood-brain barrier and the placenta by diffusion. The best approach to prevent prenatal cocaine exposure is to stop cocaine use. However, only 25% of cocaine users can discontinue their use during pregnancy. Anti-cocaine vaccination decreases cocaine passage through the blood-brain barrier. This study describes an innovative approach for preventing prenatal cocaine exposure using the GNE-KLH anti-cocaine vaccine, a novel use for the named anti-drug vaccines. Here, we show that anti-cocaine vaccination with GNE-KLH produced and maintained anti-cocaine IgG antibody titres and avidity during pregnancy. These antibodies protected the pregnant rats and their pups against prenatal cocaine damage during pregnancy until weaning. The present work is the first preclinical evidence of the efficacy of an innovative mechanism to prevent prenatal cocaine exposure damage, a worldwide public health care issue. In the future, this mechanism may be useful in pregnant women with cocaine use disorder. Further studies to understand the mechanisms of how anti-cocaine antibodies exert their protective effects in pregnancy are warranted.

Calix[n]arene-based immunogens: A new non-proteic strategy for anti-cocaine vaccine. J Adv Res 2021; 38:285-298. [PMID: 35572397 PMCID: PMC9091763 DOI: 10.1016/j.jare.2021.09.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 08/13/2021] [Accepted: 09/10/2021] [Indexed: 11/17/2022] Open
Abstract
The first total synthesis of the novel calix[n]arene-based immunogens V4N2 and V8N2 is reported. V4N2 and V8N2 promoted the production of cocaine antibodies and also modulated the biodistribution of [99mTc]TRODAT-1, a radiolabeled analogue of cocaine. V4N2 and/or V8N2 are potential candidates for the development of an immunogenic agent for the treatment of cocaine use disorder.
Introduction Cocaine use disorder is a significant public health issue without a current specific approved treatment. Among different approaches to this disorder, it is possible to highlight a promising immunologic strategy in which an immunogenic agent may reduce the reinforcing effects of the drug if they are able to yield sufficient specific antibodies capable to bind cocaine and/or its psychoactive metabolites before entering into the brain. Several carriers have been investigated in the anti-cocaine vaccine development; however, they generally present a very complex chemical structure, which potentially hampers the proper assessment of the coupling efficiency between the hapten units and the protein structure. Objectives The present study reports the design, synthesis and preclinical evaluation of two novel calix[n]arene-based anti-cocaine immunogens (herein named as V4N2 and V8N2) by the tethering of the hydrolysis-tolerant hapten GNE (15) on calix[4]arene and calix[8]arene moieties. Methods The preclinical assessment corresponded to the immunogenicity and dose–response evaluation of V4N2 and V8N2. The potential of the produced antibodies to reduce the passage of cocaine analogue through the blood–brain-barrier (BBB), modifying its biodistribution was also investigated. Results Both calix[n]arene-based immunogens elicited high titers of cocaine antibodies that modified the biodistribution of a cocaine radiolabeled analogue (99mTc-TRODAT-1) and decreased cocaine-induced behavior, according to an animal model. Conclusion The present results demonstrate the potential of V4N2 and V8N2 as immunogens for the treatment of cocaine use disorder.

Smartphone and Facebook addictions share common risk and prognostic factors in a sample of undergraduate students. TRENDS IN PSYCHIATRY AND PSYCHOTHERAPY 2020; 41:358-368. [PMID: 31967196 DOI: 10.1590/2237-6089-2018-0069] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Accepted: 03/08/2019] [Indexed: 11/21/2022]
Abstract
INTRODUCTION To improve the comprehension of the interface between smartphone addiction (SA) and Facebook addiction (FA), we hypothesize that the occurrence of both technological addictions correlate, with higher levels of negative consequences. Moreover, we hypothesize that SA is associated with lower levels of social support satisfaction. METHODS We recruited a convenience sample of undergraduate students from Universidade Federal de Minas Gerais, with age ranging between 18 and 35 years. All subjects completed a self-fulfilled questionnaire comprising sociodemographic data, the Brazilian Smartphone Addiction Inventory (SPAI-BR), the Bergen Scale for Facebook Addiction, the Barrat Impulsivity Scale 11 (BIS-11), the Social Support Satisfaction Scale (SSSS), and the Brief Sensation Seeking Scale (BSSS-8). After completing the questionnaire, the interviewer conducted a Mini-International Neuropsychiatric Interview (MINI). RESULTS In the univariate analysis, SA associated with female gender, with ages 18 to 25 years, FA, substance abuse disorders, major depressive disorder, anxiety disorders, low scores in SSSS, high scores in BSSS-8, and high scores in BIS. The group with SA and FA presented a higher prevalence of substance abuse disorders, depression, and anxiety disorders when compared to the group with SA only. CONCLUSION In our sample, co-occurrence of SA and FA correlated with higher levels of negative consequences and lower levels of social support satisfaction. These results strongly suggest that SA and FA share some elements of vulnerability. Further studies are warranted to clarify the directions of these associations.

Skeletal muscle mass index and phase angle are decreased in individuals with dependence on alcohol and other substances. Nutrition 2019; 71:110614. [PMID: 31869659 DOI: 10.1016/j.nut.2019.110614] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2019] [Revised: 08/16/2019] [Accepted: 10/05/2019] [Indexed: 01/19/2023]
Abstract
OBJECTIVE The aim of this study was to evaluate whether low skeletal muscle mass index (SMI) and low phase angle (PhA) are associated with demographic, clinical, lifestyle, and nutritional status in patients dependent on alcohol and other substances. METHODS We prospectively included 63 individuals dependent on alcohol and other substances and 71 age- and sex-matched healthy controls. Body composition was assessed by bioelectrical impedance analysis. Subjective global assessment was used to evaluate malnutrition. All included participants underwent a psychiatric evaluation, including the administration of the Mini-International Neuropsychiatric Interview. Univariate and multivariate analysis were performed to evaluate associations between low skeletal muscle mass index (SMI) and low phase angle (PhA) and nutritional, lifestyle, and alcohol use and cocaine/crack use variables, controlling for sex and age. RESULTS Low SMI and low PhA were identified in 11.1% and 44.5% of the substance dependents, respectively. Low midarm muscle circumference (r = 0.58; P < 0.001), low midarm muscle area (r = 051; P < 0.001), and reduced PhA (r = 0.59; P < 0.001) were positively correlated with low SMI. Multivariate analysis showed that heavy alcohol consumption (≥80 g·d· ≥5 y-1; odds ratio [OR], 2.33; 95% confidence interval [CI], 1.12-4.84; P = 0.02) and sedentary lifestyle (OR, 4.39; 95% CI, 1.29-14.89; P = 0.02) were independently associated with reduced SMI. Low PhA was independently associated with heavy alcohol consumption (OR, 3.64; 95% CI, 1.62-8.15; P = 0.002) and cocaine or crack use (OR, 3.97; 95% CI, 1.05-15.11; P = 0.04) in multivariate analysis. CONCLUSIONS Low SMI and low PhA are independently associated with heavy alcohol consumption. Low PhA is independently associated with cocaine or crack use.

Abstract
OBJECTIVES Understanding whether cannabidiol (CBD) is useful and safe for the treatment of psychiatric disorders is essential to empower psychiatrists and patients to take good clinical decisions. Our aim was to conduct a systematic review regarding the benefits and adverse events (AEs) of CBD in the treatment of schizophrenia, psychotic disorders, anxiety disorders, depression, bipolar disorder and substance-use disorders. METHODS We conducted a literature search in PubMed, Scielo, and Clinicaltrials.gov databases. Evidence was classified according to the WFSBP task forces standards. RESULTS Bibliographic research yielded 692 records. After analysis, we included six case reports and seven trials, comprising 201 subjects. Most the studies published presented several drawbacks and did not reach statistical significance. We have not found evidence regarding major depressive and bipolar disorders. The level of evidence for cannabis withdrawal is B; cannabis addiction is C2; treatment of positive symptoms in schizophrenia and anxiety in social anxiety disorder is C1. Discrete or no AEs were reported. The most frequently reported AEs are sedation and dizziness. CONCLUSIONS The evidence regarding efficacy and safety of CBD in psychiatry is still scarce. Further larger well-designed randomised controlled trials are required to assess the effects of CBD in psychiatric disorders.

Bad Choices Make Good Stories: The Impaired Decision-Making Process and Skin Conductance Response in Subjects With Smartphone Addiction. Front Psychiatry 2019; 10:73.

Abstract
Introduction: Smartphone Addiction (SA) has caused negative consequences and functional impairments in college students, such as reduction of academic performance and impairment in sleep quality. Studies have shown that individuals with chemical and behavioral dependencies have a bias in decision-making process, which leads to short-term advantageous choices even if they cause long-term harm. This bias in decision-making process is accompanied by a change in somatic markers and is associated with the development and maintenance of addictive behavior. The decision-making process and the measurement of physiological parameters have not yet been analyzed in SA. The neuropsychological and physiological characterization of the SA can contribute to its approach with the other dependency syndromes and to its recognition as a disease. Objective: we aimed to evaluate the decision-making process under risk and under ambiguity in individuals with SA and to measure the physiological parameters that accompany this process. Method: We compared the performance in the Iowa Gambling Task (IGT), Game of Dice Task (GDT) and skin conductance response (SCR) between 50 individuals with SA and 50 controls. Results: Smartphone dependents presented a profile of impairment in decision-making under ambiguity, without impairment in decision-making under risk. They demonstrated lower SCR before disadvantageous choices, higher SCR after rewards and lower SCR after punishments during decision-making, which suggests difficulty in recognizing disadvantageous alternatives, high sensitivity to rewards, and low sensitivity to punishments. Conclusion: The impairment in the decision-making process in smartphone dependents is similar to that found in other chemical and behavioral addictions, such as alcohol addiction, gambling disorders and pathological buy. The impairment in decision under ambiguity with preservation of decision under risk may reflect dysfunction of implicit emotional processes without dysfunction of explicit cognitive process. This profile can contribute to the recognition of SA as a behavioral dependence and to guide specific preventive and therapeutic strategies.

Abstract
AIM To identify factors associated with depressive symptoms among inpatients with cardiovascular disease (CVD).
METHODS This is a cross-sectional study performed in a subsample of a large cross-sectional research that investigated affective disorders and suicide behaviour among inpatients hospitalized in non-surgical wards of the University Hospital of the Federal University of Minas Gerais from November 2013 to October 2015. Sociodemographic and clinical data were obtained through a structured interview and medical record review. Depression was assessed by the depression subscale of the Hospital Anxiety and Depression Scale, with scores ≥ 8 considered as positive screening for depression. We used the Fageström Test for Nicotine Dependence to characterize nicotine dependence. For assessing resilience and early-life trauma, we used the raw scores of the Wagnild and Young Resilience Scale and Childhood Trauma Questionnaire, respectively.
RESULTS At endpoint, we included 137 subjects. Thirty-eight (27.7%) subjects presented depressive symptoms and nine (23.7%) of those were receiving antidepressant treatment during hospitalization. The female sex; a lower mean educational level; a greater prevalence of previous suicide attempts; a higher level of pain; a higher prevalence of family antecedents of mental disorders; a lower resilience score; and higher childhood trauma score were the factors significantly associated with screening positive for major depression (P < 0.05). Multivariate analysis demonstrated that the factors independently associated with the depressive symptoms were a higher childhood trauma severity (OR = 1.06; P = 0.004); moderate to severe nicotine dependence (OR = 8.58; P = 0.008); and the number of previous hospital admissions (OR = 1.11; P = 0.034). The obtained logistic model was considered valid, indicating that the three factors together distinguished between having or not depressive symptoms, and correctly classified 74.6% of individuals in the sample.
CONCLUSION Our results demonstrate that inpatients presenting both CVD and a positive screening for depression are more prone to have antecedents of childhood trauma, nicotine dependence and a higher number of previous hospitalizations.

Abstract
OBJECTIVE To translate, adapt and validate the Smartphone Addiction Inventory (SPAI) in a Brazilian population of young adults. METHOD We employed the translation and back-translation method for the adaptation of the Brazilian version SPAI (SPAI-BR). The sample consisted of 415 university students. Data was collected through an electronic questionnaire, which consisted of the SPAI-BR and the Goodman Criteria (gold standard). The retests were carried out 10-15 days after the initial tests with 130 individuals. RESULTS The SPAI-BR maintained semantic, idiomatic and conceptual equivalences from the original scale. The Confirmatory Factor Analysis confirmed the One-factor model of the SPAI with good fit indexes (x2 = 767.861, CFI = 0.913, TLI = 0.905, RMSE = 0.061, WRMR = 1.465). The Kuder-Richardson Coefficient showed good internal consistency. The analysis of the ROC curve established an area under the curve of 86.38%. The Intraclass-Correlation Coefficient of 0.926 between the test and the retest demonstrated an excellent temporal stability. The high correlation between SPAI-BR and the Goodman Criteria (rs = 0.750) established the convergent validity. CONCLUSION The SPAI-BR is a valid and reliable tool for the detection of Smartphone Addiction in Brazilian university students.

Abstract
Klinefelter syndrome (KS) is the most common sex chromosomal disorder with an estimated prevalence of 1 in 500-1000. Increased incidences of anxiety, depression, substance abuse, psychotic and behavioral disorders, and sexual disorders have been reported in patients with KS. The aim of this case study was to report a case of a man with untreated KS who was also diagnosed with type II bipolar disorder. This case report raises awareness regarding psychiatric diagnoses that may be associated with such a highly prevalent condition. A 46-year-old man who had previously been diagnosed with an untreated KS was examined in our Psychiatric Department with an acute hypomanic episode. Clinical improvement was observed within 4 days and psychiatric symptoms were resolved in 7 days without use of medication. A psychiatric history of a depressive episode and at least two hypomanic episodes, as well as a family history of two relatives diagnosed with bipolar disorder, strongly suggest that our patient has type II bipolar disorder. Bipolar disorder may be a comorbid disorder in patients with KS. Routine screening for mood disorders and appropriate referral and evaluation should be performed. Future genetic research is warranted to explore why some chromosomal abnormalities (e.g., duplications), especially those located on the X chromosome, such as Klinefelter syndrome, may be associated with a bipolar or psychotic disorder in some individuals but not in others.

Abstract
BACKGROUND Antenatal depression (AD) can have devastating consequences. No existing scales are specifically designed to measure it. Common practice is to adapt scales originally developed for other circumstances. We designed this study to validate and determine the psychometric values for AD screening in Brazil. METHODS We collected clinical and socio-demographic data in the second gestational trimester. The following instruments were also administered during that period: MINI-PLUS, EPDS, BDI and HAM-D. RESULTS At the time of assessment, 17.34% of the patients were depressed, and 31.98% met the diagnostic criteria for lifetime major depression. All instruments showed an area under the curve in a receiver operating characteristic analysis greater than 0.85, with the BDI achieving a 0.90 and being the best-performing screening instrument. A score ≥11 on the EPDS (81.58% sensitivity, 73.33% specificity), ≥15 on the BDI (82.00% sensitivity, 84.26% specificity) and ≥9 on the HAM-D (87.76% sensitivity, 74.60% specificity) revealed great dichotomy between depressed and non-depressed patients. Spearman׳s rank correlation coefficients (ρ) among the scales had good values (EPDS vs. BDI 0.79; BDI vs. HAM-D 0.70, and EPDS vs. HAM-D 0.67). LIMITATIONS This study was transversal, assessing only women in the second gestational trimester. Results may be applicable only to the Brazilian population since psychometric properties may vary with the population under study. Major depression can amplify somatic symptomatology, affecting depressive rating scale data. CONCLUSION AD is highly prevalent in Brazil. To address the problem of under-recognition, physicians can use the EPDS, BDI and HAM-D to identify AD.

Abstract
Postpartum depression is one of the most prevalent psychopathologies. Its prevalence is estimated to be between 10% and 15%. Despite its multifactorial etiology, it is known that genetics play an important role in the genesis of this disorder. This paper reviews epidemiological evidence supporting the role of genetics in postpartum depression (PPD). The main objectives of this review are to determine which genes and polymorphisms are associated with PPD and discuss how this association may occur. In addition, this paper explores whether these genes are somehow related to or even the same as those linked to Major Depression (MD). To identify gaps in the current knowledge that require investigation, a systematic review was conducted in the electronic databases PubMed, LILACS and SciELO using the index terms “postpartum depression” and “genetics”. Literature searches for articles in peer-reviewed journals were made until April 2014. PPD was indexed 56 times with genetics. The inclusion criteria were articles in Portuguese, Spanish or English that were available by institutional means or sent by authors upon request; this search resulted in 20 papers. Genes and polymorphisms traditionally related to MD, which are those involved in the serotonin, catecholamine, brain-derived neurotrophic factor and tryptophan metabolism, have been the most studied, and some have been related to PPD. The results are conflicting and some depend on epigenetics, which makes the data incipient. Further studies are required to determine the genes that are involved in PPD and establish the nature of the relationship between these genes and PPD.

Abstract
OBJECTIVE Psychiatric symptoms emerge in the early stages of anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis, and patients often seek treatment in psychiatric departments before visiting any other general medical services. Numerous articles about anti-NMDAR encephalitis have been published in the scientific community worldwide, but few emphasize the role of psychiatry in symptom management. CASE DESCRIPTION We describe the case of a patient with anti- -NMDAR encephalitis seen in our service and discuss the management of behavioral symptoms based on current scientific literature. High doses of atypical antipsychotics and benzodiazepines were used to control agitation, and trazodone was administered to treat insomnia. COMMENTS Consultation-liaison psychiatry may help the healthcare team adjust the management of neuropsychiatric complications that might affect inpatients with anti-NMDAR encephalitis.

Abstract
The treatment of paraphilias remains a challenge in the mental health field. Combined pharmacologic and psychotherapeutic treatment is associated with better efficacy. The gold standard treatment of severe paraphilias in adult males is antiandrogen treatment with cognitive behavioral therapy. Selective serotonin reuptake inhibitors have been used in mild types of paraphilia and in cases of sexual compulsions and juvenile paraphilias. Antiandrogen treatments seem to be effective in severe paraphilic subjects committing sexual offenses. In particular, gonadotropin-releasing hormone analogs have shown high efficacy working in a similar way to physical castration but being reversible at any time. Treatment recommendations, side effects, and contraindications are discussed.

[PMID: 22739113 DOI: 10.1016/j.genhosppsych.2012.05.010] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2012] [Revised: 05/21/2012] [Accepted: 05/29/2012] [Indexed: 11/26/2022]
Abstract
OBJECTIVE The objective was to report a case of experienced psychosis during the treatment with methylphenidate (MPH) in a cocaine-dependent adult treated for attention-deficit/hyperactivity disorder (ADHD) with comorbid cocaine dependence. CONCLUSION ADHD is a frequent comorbidity in substance use disorder (SUD) patients. MPH may be effective in treating ADHD symptoms in SUD patients, thus preventing possible adverse outcomes. Cocaine-induced psychosis may be a risk factor for development of psychosis in the presence of a concurrent treatment with MPH.

War stress may be another risk factor for eating disorders in civilians: a study in Lebanese university students. Gen Hosp Psychiatry 2013; 35:393-7. [PMID: 23557894 DOI: 10.1016/j.genhosppsych.2013.02.007] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2012] [Revised: 02/15/2013] [Accepted: 02/16/2013] [Indexed: 10/27/2022]
Abstract
OBJECTIVE Traumatic life events are important risk factors for eating disorders (ED). War has been associated, in military populations, with an increased post-service incidence of ED and an increased mean body mass index. We hypothesize that a modification of eating behavior (EB) related to stress during wartime may increase the risk of developing an ED later on among civilians exposed to war stress during adulthood. METHODS This descriptive cross-sectional study was performed in a group of 303 undergraduate young adult students of both sexes from Lebanon, 6 months after the July 2006 war. Modification of EB during wartime, sociodemographic and other potential risk factors were assessed retrospectively. Students were then screened for ED using the SCOFF questionnaire. RESULTS SCOFF was positive in 31.4% of the students, with a mean value 41.6% higher among subjects who reported an altered EB during the war. Among subjects with a positive SCOFF screening, 71% had experienced a change of EB during wartime. Alteration of EB during war was related to an odds ratio for a positive SCOFF screening of 2.6 (95% CI 1.54-4.34) and 1.8 (95% CI 1.01-3.21) for non-adjusted and adjusted analysis, respectively. CONCLUSIONS Modification of EB related to stress during wartime is associated with an increased risk of eating disorders. Early detection and treatment of eating disorders may be improved by routinely evaluation of EB modification in patients with a past history of war exposure.

Abstract
Sexual offending is both a social and a public health issue. Evidence demonstrates that a combination of pharmacological and psychotherapeutic approaches may reduce or even eliminate deviant sexual behavior in sex offenders with paraphilic disorders. In this article, we will review pharmacological treatment options for sex offenders with paraphilias. Both serotonin selective reuptake inhibitors (SSRIs) and antiandrogen treatments have been used with reported success in decreasing recidivism. SSRIs have been used in mild types of paraphilias and juvenile paraphilias. Antiandrogen treatments seem to be effective in severe sex offenders with paraphilic disorders in order to reduce victimization. Combined pharmacological and psychotherapeutic treatment is associated with better efficacy. Imaging studies may improve the knowledge of paraphilic disorders and the mechanisms of action of current treatments. In spite of existing evidence, there is a need for independent, large-scale and good quality studies assessing the long-term efficacy and tolerance of treatments.

Autoantibodies reacting with vasopressin and oxytocin in relation to cortisol secretion in mild and moderate depression. Prog Neuropsychopharmacol Biol Psychiatry 2011; 35:118-25. [PMID: 20932870 DOI: 10.1016/j.pnpbp.2010.09.021] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2010] [Revised: 09/29/2010] [Accepted: 09/29/2010] [Indexed: 01/23/2023]
Abstract
BACKGROUND Abnormal vasopressin (VP) and oxytocin (OT) signaling may contribute to the altered activity of the hypothalamo-pituitary-adrenal (HPA) axis in major depression; however, the underlying mechanisms remain uncertain. This study characterized plasma levels and affinities of OT- and VP-reactive autoantibodies (autoAbs) in relation to disease severity and plasma cortisol response to physical exercise in patients with mild and moderate depression and healthy controls. METHODS Physical exercise was used to elicit plasma cortisol response in 23 male patients with depression and 20 healthy controls and plasma samples were obtained before and after the exercise. Just before the exercise, patients and controls were evaluated by the Montgomery and Åsberg Depression Rating Scale (MADRS) and divided according to depression severity (14 mild and 9 moderate). Plasma levels of total and free VP- and OT-reactive IgG, IgA and IgM autoAbs were measured by ELISA and affinity of IgG and IgM autoAbs were measured by plasmon resonance technique at baseline before the exercise and analyzed with relation to the MADRS and cortisol response. Immunohistochemistry was used to evaluate autoAbs binding to the rat hypothalamus. RESULTS Plasma levels of OT- and VP-reactive total IgG autoAbs were lower in patients with moderate depression vs. controls and patients with mild depression. Plasma levels of both OT- and VP-free IgG autoAbs were negatively correlated with MADRS scores. Affinity values of IgG and IgM autoAbs for both OT and VP displayed 100 fold variability among patients or controls but no significant group differences were found. Patients with moderate depression displayed blunted response of cortisol secretion to physical exercise. Baseline levels of VP total IgG and IgM autoAbs correlated negatively and VP-free IgG autoAbs correlated positively with plasma cortisol after physical exercise. Immunostaining of magnocellular hypothalamic neurons of the supraoptic and paraventricular nuclei by plasma IgG was present in 35% of the depression and in 14% of the controls groups, but this staining was not abolished by plasma preabsorption with OT or VP peptides. CONCLUSION These data show that changes of levels but not affinity of OT- and VP-reactive autoAbs can be associated with the altered mood in subjects with moderate depression and that levels of VP-reactive autoAbs are associated with cortisol secretion.

Detection of eating disorders in patients: validity and reliability of the French version of the SCOFF questionnaire. Clin Nutr 2010; 30:178-81. [PMID: 20971536 DOI: 10.1016/j.clnu.2010.09.007] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2010] [Revised: 09/15/2010] [Accepted: 09/20/2010] [Indexed: 11/18/2022]
Abstract
BACKGROUND & AIMS Although eating disorders prevalence is increasing, they are often under diagnosed in cases of unspecific signs of malnutrition. Screening scales may allow earlier diagnosis and nutritional intervention. This study aimed to evaluate the validity of the French version (SCOFF-F) of the SCOFF questionnaire for the detection of eating disorders among a female patient population referred to a clinical nutrition unit. METHODS After answering the 5 dichotomous questions of the paper version of SCOFF-F, patients were evaluated by one eating disorders specialist blinded to questionnaire results, using the MINI and Diagnosis and Statistical Manual for Mental diseases (DSM-IV) criteria as a gold standard. RESULTS Patients with anorexia nervosa (n = 67) and with bulimia nervosa (n = 45) were assessed. Age-matched healthy female students (n = 114) served as control group. At a cut-off of two positive responses, the sensibility, specificity and the area under the curve of SCOFF-F were 94.6%, 94.7% and 97.9% respectively. Cohen's kappa coefficient between SCOFF-F and MINI results was 89%. CONCLUSIONS The results of this study confirm the reliability of SCOFF-F as a screening and diagnostic-facilitating test for eating disorders in a French-speaking female patient population. SCOFF-F should help professionals in clinical nutrition to achieve earlier diagnosis and care of eating disorder patients.

Abstract
OBJECTIVE The aim of this study was to translate and validate a French version of the English SCOFF questionnaire for the screening of eating disorders (ED) in a student population. METHODS The translation and back-translation method were employed for adaptation of the French version of SCOFF (SCOFF-F). SCOFF-F paper questionnaire was given to female students attending yearly evaluation in the University Preventive Medicine Department. After completing the SCOFF-F, each student was evaluated by one ED specialist blinded to SCOFF-F results. The validated French version of Mini International Neuropsychiatric Interview (MINI) and DSM-IV criteria for ED were employed as diagnostic references. RESULTS A total of 400 women were evaluated. ED were diagnosed in 37 (9.3%) of students: eight (2%) cases of anorexia nervosa (AN) and 29 (7.3%) of bulimia nervosa (BN). Diagnostic threshold was fixed at two positive answers with a sensitivity of 94.6%, a specificity of 94.8% and an area under the curve of 96.2%. Positive and negative predictive values for ED were 65 and 99%. Similar figures were obtained separately for AN and BN. CONCLUSION This study demonstrates that the French version of SCOFF questionnaire is accurate and reliable for the detection of women with EDs in this high-risk student population.

Abstract
BACKGROUND Obesity represents a major public health problem in western countries. Initial studies suggest that injection of botulinum A toxin (Btx-A) into the antropyloric region inhibits propulsive contractions of the antral pump, with delay in gastric emptying, early satiety and weight loss. METHODS After approval by the University Ethics Committee, we prospectively evaluated 12 patients with class III obesity divided into 4 groups of 3 patients each. In groups I and II, 200 U Btx-A were injected into the antropyloric region at 8 and 16 sites, respectively. Groups III and IV received 300 U Btx-A into the antropyloric region at 16 and 24 sites, respectively. Body weight and gastric emptying time (GET) of solids and semi-solids using 13C-octanoic acid breath test and 13C-acetic acid breath test, respectively, were determined before and after injection over a period of 12 weeks. RESULTS Pre- and post-treatment body weight or solid and semi-solid GET did not differ significantly between groups (P>0.05). All patients reported a feeling of early satiety. No adverse effects related to BtxA or complications resulting from the endoscopic procedure were observed. CONCLUSION The injection of different doses of BtxA at different sites in the antropyloric region of patients with class III obesity did not interfere significantly with the solid and semi-solid GET or body weight of these individuals. However, early satiety was reported by all patients, the procedure was safe and no side-effects of the treatment were observed. Further controlled studies involving different methodologies regarding dosage of Btx-A and sites of injection are necessary.
