Although less than half of all patients with mental disorders seek mental health treatment per se, approximately 80% of all people will visit their primary care physician (PCPs) within a year (Strosahl, 1998). However, it is not well understood how to best handle patients presenting with mental health issues in primary care practices. The purpose of this project was to implement an intervention involving a screening measure for anxiety and mood disorders in a primary care setting to increase the volume of anxiety and mood disorder screening, to increase the accuracy of disorder detection, and to also enhance PCPs patterns of referral to mental health professionals (MHPs). Though starting with a quantitative design, difficulties encountered throughout the project eventually led to a largely qualitative analysis, which did yield useful information. A pilot project demonstrated anxiety and mood disorders were commonly noted in patients’ medical charts (46%), but also found referrals were rarely made for mental health services (7%), despite colocation of a licensed psychologist and licensed clinical social worker within the practice. This indicated that services available to provide comprehensive integrated total health care may not be have been used to their full potential. In the main project, 59 participants from a family medicine clinic and 20 PCPs from that clinic participated. The My Mood Monitor (M3) was administered to the patients and became part of their Electronic Medical Records (EMR). The M3 screens for anxiety, depression, and bipolar disorders within primary care settings. In 2 separate noon conferences, PCPs were trained on diagnostic criteria for anxiety disorders and mood disorders, interpretation of M3 results, and the internal Mental Health Professional referral process. The project was hampered by a full-scale switch from paper-based medical records to an EMR and accompanying lack of user experience with EMR functions, lack of efficient transfer of M3 results into the EMR, and an unforeseen switch of psychologists mid-way through the study. However, results were obtained that showed relatively low levels of PCP review of M3 results, potentially high rates of anxiety disorders and mood disorders within the setting, relatively high levels of PCP knowledge of diagnostic criteria for anxiety and mood disorders, and that patients may not prefer a ‘warm handoff’ model of mental health referral. These findings are couched within a number of important caveats, but future directions for research were clearly implied.

Background Affective disorders are poorly defined and studied in sub-Saharan Africa despite their substantial public health impact. Objectives Overall objective: To describe the epidemiology of selected affective disorders in rural Ethiopia. Specific objectives 1. To describe the validity and utility of the concept of minor depressive disorder (mD). 2. To describe the manifestation, prevalence and the short-term clinical and functional course and outcome of bipolar disorder. Subjects and methods Population: Zay community residents (age ≥16), and residents of Butajira (ages 15-49), in Southern Ethiopia. Study design: Population-based cross-sectional and longitudinal studies Case identification: For the identification of cases with bipolar disorder, a two stage process was employed. An initial screen used key informants and interview with the Composite International Diagnostic Interview (CIDI) to identify cases with probable bipolar disorder. A second confirmatory diagnostic assessment stage employed the Schedules for Clinical Assessment in Neuropsychiatry (SCAN). For the identification of cases with mD, data from the CIDI was used. Follow-up: 312 cases with bipolar disorder from Butajira were followed up for a mean of 2.5 years (ranging 1-4 years) through monthly clinical assessments and annual symptom and functional ratings. Results The CIDI was administered to 1714 adults among the Zay and to 68, 378 adults among the Butajira residents. The prevalence of mD among the Zay and Butajira was 20.5% and 2.2% respectively. Up to 80% of cases with mD had used services for their symptoms, while a third to a half of cases had thought about self harm. Up to a sixth of cases had attempted suicide. Age, marital status, education and somatic symptoms were independently associated with mD. The prevalence of bipolar disorder among the Zay was 1.8%. During a 2.5-year follow-up of 312 cases with bipolar disorder from Butajira, 65.9% relapsed (47.8% manic, 44.3% depressive and 7.7% mixed episodes) while 31.1% experienced persistent illness. Female gender predicted depressive relapse whereas male gender predicted manic relapse. Only being on psychotropic medication predicted remission (OR=3.42; 95% CI=1.82, 6.45). Disability was much worse among bipolar patients than in the general population and was predicted by symptom se3verity. Conclusions This is the largest study on mD and bipolar disorder in Africa. mD appears to have potential clinical utility in this setting given its association with service use and risk. The identified risk factors for mD also suggest potential aetiological continuity with major depression. The relatively high prevalence of bipolar disorder among the Zay may be related to genetic predisposition perhaps mediated through a founder effect, but other factors need exploring. In relation to the outcome of bipolar disorder, this study indicates that, contrary to previous assumptions, the course of bipolar disorder is characterised by both manic and depressive relapses in a relatively proportionate fashion. Bipolar disorder also leads to significant levels of disability. This is the only prospective outcome study of bipolar disorder in Africa where cases were monitored systematically at short assessment intervals. Therefore, findings are likely to be more robust than previous reports.

Au niveau mondial, la mort par suicide occupe fréquemment la deuxième ou troisième place des causes de décès chez les adolescents (AIPS, 2009). Afin de prévenir le suicide chez les jeunes, une meilleure compréhension des facteurs associés s’avère donc nécessaire. La présente étude avait pour but d’identifier les facteurs de protection d’adolescents atteints d’un trouble de l’humeur et présentant un risque suicidaire. Pour ce faire, un questionnaire relatant les habitudes de vie et facteurs psychosociaux a été analysé. Le risque suicidaire a été évalué à partir de la version adaptée pour adolescents du SAD PERSONS Scale (Juhnke, 1994). L’échantillon de l’étude comprenait 101 jeunes de 12 à 17 ans atteints d’un trouble de l’humeur et présentant un risque suicidaire. Des analyses descriptives, des tests de t, des analyses de variance, des corrélations et des régressions ont été utilisées afin de vérifier la relation entre le risque suicidaire et les facteurs de protection. Il ressort que, pour les adolescents de l’étude, être satisfait du soutien reçu, avoir un bon soutien affectif parental, avoir plusieurs sources de lecture par semaine, souper plusieurs fois avec sa famille par semaine, ne pas fumer de cigarette, ne pas avoir beaucoup d’amis qui fument la cigarette, ne pas consommer d’alcool, ne pas consommer de drogue ainsi que de ne pas mélanger la consommation d’alcool et de drogue peuvent tous agir, individuellement, comme facteurs de protection du suicide chez des adolescents atteints d’un trouble de l’humeur et présentant un risque suicidaire. Par ailleurs, les analyses effectuées ne révèlent aucune relation significative entre les habitudes scolaires, l’activité physique, les habitudes de sommeil, l’estime de soi et le risque suicidaire des adolescents de l’étude. Enfin, miser sur les facteurs de protection du suicide identifiés par la présente étude constitue une nouvelle piste intéressante pour les infirmières et des recommandations pour la recherche et la pratique infirmière sont suggérées. / Adolescent suicide often represents the second or third leading cause of death for this age group throughout the world (AIPS, 2009). In order to prevent adolescent suicide, a better understanding of the factors associated with suicidal risk is necessary. The aim of this study was to identify the protective factors of adolescents with mood disorders and suicidal risk. Life habits and psychosocial factors were evaluated by an auto-administrated questionnaire. The adapted version of the SAD PERSONS Scale (Patterson, Dohn, Bird & al, 1983) for children and adolescents (Juhnke, 1994) was used to evaluate the suicidal risk. The sample of this study included 101 teenagers, aged between 12 and 17 years old, who had a mood disorder and a suicidal risk. Descriptive analysis, T-tests, variance analysis (ANOVA), correlation analysis and multiple regressions were conducted to examine the relationship between the suicidal risk (dependant variable) and the life habits and psychosocial factors (independent variables). The results indicate that, for 12 to 17 year olds, being satisfied with the support received, having good parental support, having many different sources of reading, eating supper with their family frequently, not smoking cigarettes, not having many friends who smoke cigarettes, not drinking, not doing drugs and not drinking and doing drugs simultaneously can all act as individual protective factors for suicidal risk. On the other hand, the results of this study do not show any statistically significant relations between school habits, physical activity, sleep habits, self-esteem and suicidal risk for teenagers with mood disorders. Finally, examining protective factors seems to be useful in helping teens with mood disorders and suicidal risk. The results of this study encourage nurses to include protective factors in their evaluation of suicidal adolescents and interventions. Research and clinical recommendations are therefore suggested.

O Câncer Colorretal (CCR) consiste no terceiro tipo de câncer mais comum em homens e o segundo em mulheres. O tratamento, na maioria dos casos, implica na cirurgia geradora de estoma, que constitui um procedimento invasivo, com grande impacto em todas as áreas na vida da pessoa. O presente estudo teve por objetivos investigar prospectivamente variáveis relacionadas à imagem corporal, sintomas ansiosos e depressivos, domínios da Qualidade de Vida Relacionada a Saúde (QVRS) e as cognições, emoções e comportamentos diante do processo de adaptação ao estoma. Trata-se de um estudo exploratório, longitudinal e de abordagem quanti qualitativa. A amostra foi composta por pacientes adultos (n=122), de ambos os sexos, atendidos no Ambulatório de Estomaterapia do Hospital de Câncer de Barretos (SP). A avaliação quantitativa foi realizada em todos os pacientes e a qualitativa em 26 dos pacientes, sorteados aleatoriamente. Os participantes foram avaliados em quatro momentos (pré-operatório, três, seis e quinze meses após a cirurgia) e foram subdivididos de acordo com o tipo de procedimento cirúrgico realizado (Anastomose Primária, Estomia Intestinal Temporária e Estomia Intestinal Definitiva). Para a coleta de dados, foram utilizados os instrumentos: questionário de dados sociodemográficos; Critério de Classificação Econômica Brasil; ficha de condições clínicas; Escala de Figura de Silhuetas (EFS); Escala de Ansiedade e Depressão para Hospital Geral (HADS); Questionários para avaliação da QVRS (EORTC QLQ-C30/ QLQ-CR38); Medida subjetiva de pensamentos e emoções e Roteiro de entrevista semiestruturada. Os resultados demonstraram que a amostra foi constituída por pacientes mais velhos, de baixa renda e escolaridade. Os valores médios encontrados na avaliação da imagem corporal indicaram uma superestimação desta. Apesar dos participantes não terem apresentado sintomatologias graves para ansiedade e depressão, de acordo com a escala HADS, as comparações estatísticas infere-se que, quanto pior a sintomatologia para ansiedade e depressão, pior a saúde global. Segundo o EORTC QLQ-C30 e QLQ-CR38 a maioria dos domínios de QVRS apresentaram níveis moderados, sendo que os piores sintomas foram os sexuais. A depressão influenciou de forma direta e negativa na saúde global, assim como na acurácia da imagem corporal. Foram encontradas diferenças significantes entre os grupos na comparação das variáveis nos diversos momentos de avaliação, sugerindo que o nível dos sintomas variou de acordo com o tempo. Não foram encontradas altas frequências para as distorções cognitivas nesses pacientes, entretanto, observou-se pela entrevista semiestruturada que na primeira avaliação existia grande preocupação quanto às limitações ocasionadas pela estomia intestinal em detrimento da percepção de normalidade, frequentemente reportada na última avaliação. Conclui-se que a entrevista qualitativa complementou os resultados encontrados na abordagem quantitativa, sendo que a análise de conteúdo reforçou que os pacientes, em geral, apresentaram boa adaptação à estomia. O suporte social foi apontado como uma das principais estratégias utilizadas no processo de adaptação. Neste sentido, orientações psicoeducativas aos pacientes e familiares devem ser realizadas desde o diagnóstico, a fim de contribuir para adaptação ao estoma. / The Colorectal Cancer (CRC) is the third most common type in men and the second in women. The treatment in most cases implies a surgery with a stoma, which is an invasive procedure, with a great impact in all areas in a person\'s life. This study aimed to prospectively investigate variables related to body image, depression and anxiety symptoms, areas of Health Related Quality of Life (HRQoL) and cognitions, emotions and behaviors related to the adaptation process to the stoma. It is an exploratory study, longitudinal, with quantitative and qualitative approach. The sample consisted of adult patients (n = 122), of both sexes, attended in Stomatherapy Clinic of Barretos Cancer Hospital. The quantitative evaluation was performed in all patients and the qualitative evaluation was performed in 26 patients randomly selected. Participants were assessed at four time points (preoperative, three, six and fifteen months after surgery) and were subdivided according to the type of surgical procedure performed (Primary Anastomosis, Temporary Intestinal Ostomy and Definitive Intestinal Ostomy). For data collection, the follow instruments were used: socio-demographic questionnaire; Brazilian Economic Classification Criteria; clinical conditions record; Figures of Silhouettes Scale (FSS); Hospital Anxiety and Depression Scale (HADS); Questionnaires to assess the HRQoL (EORTC QoL-C30 / QoL-CR38); Subjective measure of thoughts and emotions and Semi-structured interviews. The results showed that the sample was composed of older patients, with low income and low education level. The mean values found in the evaluation of body image showed an overestimation of it. Although the participants did not show servere symptomatology for anxiety and depression, according to the HADS, statistical comparisons inferred that, the worse the symptoms for anxiety and depression, worse overall health. According to the EORTC QoL-C30 and QoL-CR38 most HRQoL domains showed moderate levels in which the worst symptoms were sexual. Depression had a direct and negative impact on global health, as well as the accuracy of body image. Significant differences were found between groups when comparing the variables in the different time points, suggesting that the level of symptoms varied according to the time. There were no high frequencies for cognitive distortions in these patients; however, the semi-structured interview shows that in the first assessment there was great concern about the limitations caused by intestinal ostomy at the expense of perceived \"normal\" often reported in the last assessment. We conclude that the qualitative interview complemented the findings in quantitative approach, and the content analysis emphasized that patients generally showed good adaptation to the stoma. Social support was considered one of the main strategies used in the adjustment process. In this sense, psychoeducational guidance to patients and their families must be carried out from diagnosis, in order to contribute to the adaptation to the stoma.

Lithium is a drug used to treat mood disorders and also has many side effects, including central nervous system (CNS) complications (such as cognitive dulling), associated with its use. The mechanism of its action still remains unknown. Over the years, many leads have started emerging. It has been shown to inhibit several enzymes in the cell and has been implicated in altering many neurotransmitter systems and signal transduction pathways (serotonin, dopamine and norepinephrine neurotransmissions). Effect of exposure to therapeutic levels of lithium on mature glutamatergic synapses is being studied and several changes in glutamate receptor subtypes have already been reported. Effects of lithium on developing glutamatergic synapses have not been studied. The thesis tries to document and understand the changes brought about by long term lithium treatment on developing glutamatergic synapses in vitro in hippocampal neuronal cultures. In the present work, patch clamp technique was used to monitor the changes in the postsynapse and fluorescence imaging to study the presynaptic changes. The hippocampal neuronal cultures were treated with 1 mM lithium for 6 days during the synaptogenesis stage (DIV 4-10) and termed as chronic Li treatment (CLi). Following CLi treatment the changes occurring in amplitude and rectification property of the AMPA receptor (AMPAR), a subtype of glutamate ionotropic receptor, mediated miniature excitatory postsynaptic currents (mEPSCs) have been reported (Chapter III). Lithium inhibits protein kinase A (PKA), glycogen synthase kinase–3β (GSK-3β) and glutamate reuptake. Effect of inhibiting PKA, GSK-3β and glutamate reuptake was also studied with a view to understand the molecular basis of lithium action on AMPAR mEPSCs (Chapter IV). It was found that chronic lithium treatment (CLi) caused a reduction in the mean amplitude of mEPSCs mediated by AMPARs and also changed the rectification property of these receptors from being more outwardly rectifying to being more inwardly rectifying, an indication probably of increase in contribution of Ca2+-permeable AMPARs to the synaptic events. AMPAR events in chronic lithium treated cultures were more sensitive to both N-acetyl spermine (NASPM) application and di-fluoro-methyl-ornithine (DFMO) treatment, both specific to Ca2+-permeable AMPARs, indicating that there was an increase in the contribution from Ca2+-permeable AMPARs to the synaptic events. PKA inhibition with H-89 treatment (starting from DIV 4 (for 6 days)) reduced the mean amplitude of AMPAR mEPSCs and increased the mean rectification index (RI). GSK-3β inhibition with SB415286 (starting from DIV 4 (for 6 days)) did not alter the mean mEPSC amplitude but reduced the mean RI. Transient (24 hrs) glutamate reuptake inhibition with threo-β-Hydroxy-Aspartic-Acid (THA) at DIV 4 followed by a period of recovery led to smaller amplitudes but no change in RI. The 24 hr glutamate reuptake block on DIV 4 had long term effects. It led to an increase in AMPAR mEPSC frequency while AMPAR mEPSC amplitudes were reduced. The mean RI decrease seen when glutamate reuptake was blocked for 24 hrs on DIV 10, was absent in DIV 4 THA treated neurons. However, when the neuronal cultures were maintained in the presence of PKA and GSK-3β inhibitors, the DIV 4 THA treated neurons showed AMPAR mEPSC characteristics similar to CLi neurons. Thus, it was seen that individual inhibition of PKA, GSK-3β and glutamate reuptake did not lead to changes in AMPAR mEPSCs similar to that seen in lithium treated neurons. The effect of lithium exposure during synapse development on AMPARs could be reproduced closely by co-inhibiting PKA, GSK-3β and glutamate reuptake. Using the styryl dye FM1-43, the changes induced in presynaptic release by a similar chronic lithium treatment was studied (Chapter V). It was found that lithium exposure (1 mM, DIV 4-10) brought down the extent of dye loading, destaining and also slowed down the rate of dye loss in response to high KCl stimulation (the τfast component of destaining was significantly slower). Minimum loading experiments did not reveal any difference in mode of exocytosis (kiss and run/full-collapse) in control and lithium treated cultures. Chlorpromazine treatment (that inhibits clathrin-mediated endocytosis) affected dye loading to a lesser extent in lithium treated cultures as compared to control. Surprisingly, exposure to hyperosmotic solution 10 minutes after dye wash out boosted the extent of dye loading and destaining in lithium treated cultures (a phenomenon not seen in control). This could happen if the FM1-43 is trapped away from the wash solution during the wash period. This would be possible if endocytosis in CLi takes place, differently from control, through a process involving membrane infoldings similar to bulk endocytosis albeit a slower/compromised one. Taken together, the data presented here indicates that lithium treatment during synaptogenesis affects vesicular recycling mostly at the endocytosis and docking/priming steps (mobilization of vesicles for release). Lithium treated cultures also did not show the high KCl associated presynaptic potentiation observed in control which is a significant finding. In conclusion, chronic lithium treatment affected both the presynaptic and postsynaptic compartments of the glutamatergic synapse. The effect of lithium on AMPAR mEPSC could not be reproduced by individual inhibitions of biochemical effectors but by multiple inhibitions. Thus, the study done here underscores the need to look at the manifold effect of lithium in an integrated way. The study also might have implications in understanding the CNS complications seen in patients taking lithium treatment and in babies perinatally exposed to lithium.

A gold standard measurement does not exist to assess fatigue symptoms across patient populations. Current tools only consist of self-report measures that may not assess fatigue objectively. The National Institutes of Health-Brief Fatigue Inventory (NIH-BFI) is a clinician-administered instrument developed as a more objective assessment of fatigue symptoms. This study assessed the NIH-BFI's validity in diverse clinical populations, which included patients diagnosed with a mood disorder, Parkinson's disease, cancer, and healthy controls. Results suggest good criterion-related and convergent validity for the NIH-BFI. Results also indicate significant differences in fatigue severity between cohorts. Moreover, the data also suggest significant differences among groups in depression, anxiety, pain catastrophizing, sleep quality, global mental and physical health, and cognitive functioning. This study proposes that the NIH-BFI is a valid clinician-administered measure of fatigue that can be administered in multiple clinical populations.
