Abstract
Objectives Mental health is essential for overall health and is influenced by different social determinants. The aim of this paper was to examine which determinants are associated with mental health inequalities among people with selected citizenships in Germany. Methods Data were derived from the multilingual interview survey "German Health Update: Fokus (GEDA Fokus)" among adults with Croatian, Italian, Polish, Syrian, or Turkish citizenship (11/2021-05/2022). Poisson regressions were used to calculate prevalence ratios for symptoms of depression (PHQ-9) and anxiety disorder (GAD-7). Results Sociodemographic (sex, income, age, household size) and psychosocial (social support and self-reported discrimination) determinants were associated with symptoms of depression and/or anxiety disorder. The prevalence of mental disorders varied most by self-reported discrimination. Conclusion Our findings suggest mental health inequalities among people with selected citizenships living in Germany. To reduce these, social inequities and everyday discrimination need to be addressed in structural prevention measures as well as in interventions on the communal level. Protective factors (e.g., social support) are also important to reduce mental health inequalities on the individual and community level.

Abstract
Current psychiatric diagnoses are not defined by neurobiological measures which hinders the development of therapies targeting mechanisms underlying mental illness 1,2 . Research confined to diagnostic boundaries yields heterogeneous biological results, whereas transdiagnostic studies often investigate individual symptoms in isolation. There is currently no paradigm available to comprehensively investigate the relationship between different clinical symptoms, individual disorders, and the underlying neurobiological mechanisms. Here, we propose a framework that groups clinical symptoms derived from ICD-10/DSM-V according to shared brain mechanisms defined by brain structure, function, and connectivity. The reassembly of existing ICD-10/DSM-5 symptoms reveal six cross-diagnostic psychopathology scores related to mania symptoms, depressive symptoms, anxiety symptoms, stress symptoms, eating pathology, and fear symptoms. They were consistently associated with multimodal neuroimaging components in the training sample of young adults aged 23, the independent test sample aged 23, participants aged 14 and 19 years, and in psychiatric patients. The identification of symptom groups of mental illness robustly defined by precisely characterized brain mechanisms enables the development of a psychiatric nosology based upon quantifiable neurobiological measures. As the identified symptom groups align well with existing diagnostic categories, our framework is directly applicable to clinical research and patient care.

Abstract
Background: Anxiety disorders are prevalent mental health conditions often accompanied by various comorbidities. The association between anxiety and liver disease, as well as fluctuations in blood sugar levels, highlights the importance of carefully evaluating patients with anxiety undergoing antidepressant therapy. The aim of this study was to conduct a comparative assessment of liver function and blood glucose levels in patients diagnosed with anxiety disorders while considering potential gender-specific differences. Methods: An analysis was conducted over a 24-month period. This study included 88 patients diagnosed with anxiety disorders, with symptoms severe enough to require hospitalization, aged 18 or older, undergoing antidepressant monotherapy, without any additional pathologies. Liver enzymes (AST, ALT, GGT), AST/ALT ratio, and blood glucose levels were measured and compared. Results: While no significant differences were found between antidepressant classes, increased GGT levels were observed in men older than 40 years compared to women of the same age, suggesting that alcohol consumption may be a coping mechanism for anxiety. This gender difference was not observed among young patients. Conclusions: Early detection of alcohol consumption is essential in patients with anxiety disorders in order to prevent alcohol-related liver damage and to adjust the management of both conditions accordingly.

Abstract
BACKGROUND Generalized anxiety disorder (GAD) is a common mental disorder that happens comorbidly with other diseases. Headache is a common anxiety comorbidity. Previous reports have shown that the selection of therapeutic drugs for GAD patients and comorbid headache is challenging. Therefore, our study aimed to investigate the clinical efficacy of escitalopram combined with botulinum toxin A (BoNT/A) in patients with GAD and comorbid headache and seek an alternative treatment strategy for the comorbidity of GAD and headache. METHODS A prospective, randomized controlled, double-blind study was performed. The eligible GAD patients with comorbid headache were randomly assigned to the BoNT/A group and the placebo group. All the patients were given oral escitalopram therapy (10-20 mg/day) for the whole duration of the study. The BoNT/A group was given local injections of BoNT/A (50 U per person), whereas the placebo group was given local saline (0.9% NaCl) injections at the beginning and 3 months after the experiments. All participants were followed up for 6 months and relevant information was collected at months 0, 1, 2, 3, and 6. Primary outcomes included the following: (1) the Generalized Anxiety Disorder 7 (GAD-7); (2) the Self-rating Anxiety Scale (SAS); (3) the Hamilton Anxiety Rating Scales (HAMA); (4) days with headache per month; (5) visual analogue scale (VAS). RESULTS A total of 101 patients (the sex ratio of female to male: 3.39:1) were finally included. Compared with the placebo group, the BoNT/A group showed a significant decrease in GAD-7 scores, SAS scores, HAMA scores, days with headache per month, and VAS scores at months 1, 2, 3, and 6 of follow-up (all p < 0.05). The average time to complete remission of anxiety symptoms (HAMA< 7 points) in the BoNT/A group was less than the placebo group (2 months vs. 3 months). At the same time, the results of the survival analysis showed a clear beneficial effect of BoNT/A relative to placebo on the time to remission of anxiety (log-rank test, p < 0.001). Mean daily doses of escitalopram at the sixth month in the BoNT/A group was smaller than the placebo group (12.5 mg vs. 16.04 mg, p < 0.001). The number of patients who relapsed (HAMA total score ≥ 14 points) at 6 months of follow-up in the BoNT/A group was less than the placebo group (2.2% vs. 14.9%, p < 0.05). The rates of response (HAMA subtraction rate ≥ 50%) were 93.8% for the BoNT/A group and 75.5% for the placebo group (p < 0.05), and the rates of remission (HAMA < 7 points) were 87.5% for the BoNT/A group and 64.2% for the placebo group (p < 0.01) at the sixth month. CONCLUSION The combination of escitalopram with BoNT/A is a significantly effective intervention in improving clinical efficacy and reducing the recurrence in patients with GAD and comorbid headache, and we believe that this approach will be an additional treatment strategy for future treatment of comorbid headache in GAD. Therefore, we recommend that escitalopram combined with BoNT/A should be given as early as possible in GAD patients and comorbid headache.

Abstract
BACKGROUND Elderly with mental health conditions usually use multiple medications, which predisposes them to inappropriate use of medications, which is defined as medications that should be avoided due to their risk; this outweighs their benefit given that safer alternatives are available. This study aimed to examine potentially inappropriate medication use among older patients with anxiety disorder. METHODS This study used a cross-sectional retrospective study design using twelve months of data extracted from the Electronic Health Record (EHR) database for older adults diagnosed with anxiety disorder and treated in the ambulatory care setting. Potentially inappropriate medications (PIMs) use was evaluated using the 2019 Beers criteria. Descriptive statistics were used to describe the sample. Pearson's chi-square tests (for categorical variables) and t-tests (for continuous variables) were utilized to measure the differences in independent variables between patients with and without PIMs. Binary logistic regression was used to examine the associations between PIMs use and identify potential factors for PIMs use among older adults with anxiety disorder. Analyses were performed using the Statistical Analysis Software version 9.4 (SAS® 9.4). RESULTS The study sample includes 371 older adults (age ≥ 65 years) with anxiety disorder; their average age was (72.1 ± 5.8) years. PIMs use was highly prevalent among older adults with anxiety (66.6%). About 35.6% of the study sample used one PIM, 22.6% used two PIMs, and 8.4% used three PIMs. The most frequently prescribed PIMs were NSAIDs and gastrointestinal agents. The adjusted regression analysis found that PIMs use was less likely among men than women. In addition, PIMs use was more likely among women with diabetes, cancer, and polypharmacy. CONCLUSIONS Future studies on strategies and interventions rationing PIMs use in older adults with anxiety disorder are necessary given the high prevalence of PIMs and polypharmacy within this population.

Abstract
Abstract
Background
There is a greater incidence of mental health problems among children with hearing impairment compared to controls. A high proportion of children with hearing impairment experience delays in understanding, recognizing, and using emotional expression. There are additional difficulties in post-cochlear transplant patients that may increase the risk of developing psychopathology, such as anxiety disorder.
Results
Forty mothers of children who underwent cochlear implantation surgery responded to the Spence Preschool Anxiety Scale. Socio-demographic, medical, and perioperative data of children were obtained from medical records. On the Spence Preschool Anxiety Scale, 21 out of 40 children (52.25%) have a positive total score. On obsessive–compulsive disorder, physical injury fears, generalized anxiety, separation anxiety, and social anxiety subscales, the numbers of children who scored positive are 23 (57.5%), 18 (45%), 18 (45%), 10 (25%), and 6 (15%), respectively.
Conclusion
Anxiety disorders are common in post-cochlear transplant children.

Assessing anxiety among adolescents in Hong Kong: psychometric properties and validity of the Generalised Anxiety Disorder-7 (GAD-7) in an epidemiological community sample. BMC Psychiatry 2022; 22:703.

Abstract
BACKGROUND The development of a valid and simple-to-use self-administered tool in Asian adolescents for clinical screening and intervention remains limited. The present study assessed the psychometric characteristics and validity of the Generalised Anxiety Disorder Scale-7 (GAD-7) among adolescents in Hong Kong. METHODS Epidemiological data from 3,261 Hong Kong adolescents aged 15 - 24 years were analysed for the construct validity, criterion validity, concurrent validity, and Rasch Model. All analyses were age- and gender-weighted according to the distributions of Hong Kong's general population. RESULTS The GAD-7 showed high internal consistency and strong fit to the one-factor structure. The best cut-off value was set at 7 or more. Regression models found that the total scores of the scale were positively associated with symptoms of depression and hypomania, schizotypal personality and alcohol dependence. Rasch model analysis found that the separation index was 2.18 and 16.51 for the respondents and items, respectively and all residual pairs had small correlation coefficients (i.e., < 0.3). CONCLUSIONS All psychometric findings presented in this study support the use of the GAD-7 as a legitimate measure of anxiety severity. A cut-off score of 7 should indicate a potential diagnosable condition in Asian adolescents, which requires our attention but should not be used as a formal diagnostic screening tool. The findings revealed the local dependence of the items of the GAD-7 and that the scale can separate respondents into at least two groups and items into numerous groups according to the separation index.

Abstract
BACKGROUND Pharmacological treatments for mental disorders, such as anxiety and depression, present several limitations and adverse effects. Therefore, new pharmacotherapy with anxiolytic and antidepressant potential is necessary, and the study of compounds capable of interacting with more than one pharmacological target may provide new therapeutic options. OBJECTIVES In this study, we proposed the design, synthesis of a new compound, 2-(4-((1-phenyl-1H-pyrazol-4-yl)methyl)piperazin-1-yl)ethyl acetate (LQFM192), pharmacological evaluation of its anxiolytic-like and antidepressant-like activities, as well as the possible mechanisms of action involved. METHODS Administration of LQFM192 was carried out prior to the exposure of male Swiss mice to behavioral tests, such as the elevated plus-maze and forced swimming test. The involvement of the serotonergic system was studied by pretreatment with WAY-100635 or p-chlorophenylalanine (PCPA) and the involvement of the benzodiazepine site of the GABAA receptor by pretreatment with flumazenil. RESULTS The treatment with LQFM192 at doses of 54 and 162 µmol/kg demonstrated anxiolyticlike activity that was blocked by WAY-100635, PCPA, and flumazenil pretreatments. The potential antidepressant-like activity was visualized at the same doses and blocked by WAY-100635 and PCPA. CONCLUSION In summary, the anxiolytic-like activity of LQFM192 is mediated by the serotonergic system and the benzodiazepine site of the GABAA receptor, and the antidepressant-like activity through the serotonergic system.

Abstract
Despite generalized anxiety disorder (GAD) being one of the most prevalent comorbidities in obsessive-compulsive disorder (OCD), few studies have researched its impact on the OCD phenotype. The present study investigated how the sociodemographic and clinical profile of people with OCD with comorbid GAD differs from people with OCD without comorbid GAD. We hypothesised that the phenotype of the comorbid group would be closely related to GAD, in that it would more likely be female, have an earlier age at onset of OCD, and show an increased severity of fear-related OCD symptoms (aggressive, sexual/religious, and contamination dimensions), more avoidant behaviours, greater suicidality, more severe anxiety symptoms, and increased rates of comorbid anxiety and mood disorders. The study included 867 participants with OCD, with GAD being comorbid in 33.56%. Mann-Whitney U tests, chi-square tests with continuity correction, and logistic regressions were performed. Results showed that comorbid GAD was uniquely associated with an increased number of avoidant behaviours, greater anxiety severity, panic disorder without agoraphobia, social phobia, specific phobia, and type II bipolar disorder. These results illustrate the clinical severity associated with this comorbidity and highlight markers that can aid diagnosis of GAD in OCD. Future studies should investigate whether this comorbidity has an impact on the treatment of OCD.

Abstract
INTRODUCTION In this paper, we systematically review literature from 1940 to 2000 relating to the combined use of psychological therapies and psychedelic drugs in the treatment of ICD-10 anxiety disorders. METHODS The databases Ovid MEDLINE(R), PsycINFO, and Multidisciplinary Association for Psychedelic Studies (MAPS) were searched for case reports and trials involving humans in the treatment of ICD-10 anxiety and related disorders. Twenty-four studies are described; four describe anxiety symptoms in diverse patient groups, 14 studies describe historic diagnoses that usefully correspond with ICD-10 anxiety disorders, six studies pooled results or failed to detail results specific to contemporary ICD-10 anxiety disorders. Two of the 24 studies reported are individual case reports while two of them were inadequate in terms of the reporting of outcome measures. Thus 20 studies were ultimately included in the summary analysis. RESULTS Three of the 20 studies reviewed described improvements in anxiety by standardized measures (p < .05) and two studies found that this effect was dose related. Of the 20 studies included in the final analysis, 94 of 145 (65%) cases of "psychoneurotic anxiety reaction" as defined by Diagnostic and Statistical Manual of Mental Disorders-I showed improvement that ranged from moderate improvement to full recovery. Despite methodological inadequacies, the results from previous studies are encouraging and should be used to guide and inform further investigation. CONCLUSION The majority of studies indicate that a combination of psychedelic drug administration and psychological therapy was most beneficial. We found no study suggesting that the pharmacological action of psychedelic drugs in isolation is sufficient.

Abstract
Generalized anxiety disorder (GAD) is a prevalent anxiety disorder, but is still poorly recognized in clinical practice. The aim of this review is to provide a coherent understanding of the functional neuroanatomy of GAD; second, to discuss the current theoretical cognitive models surrounding GAD; and finally to discuss the discrepancy between fundamental research and clinical practice and highlight several potential directions for future research in this domain. A systematic review of original papers investigating the neural correlates of DSM-IV and DSM-5 defined GAD samples was undertaken in Ovid literature search, PubMed, Medline, EMbase, PsycINFO, Google Scholar, and TRIP databases. Articles published between 2007 and 2018 were included. First, GAD seems to be characterized by limbic and (pre)frontal abnormalities. More specifically, GAD patients show difficulties in engaging the prefrontal cortex (PFC) and anterior cingulate cortex (ACC) during emotional regulation tasks. Second, the involved brain areas appear to be characterized by heterogeneity possibly due to a variety of experimental designs and test subjects. Third, regarding the discrimination between GAD and other anxiety disorders via fMRI, results appear to be mixed. Studies report both GAD-specific activity and an inability to differentiate between GAD and other anxiety or mood disorders. The usage of different experimental tasks, test subjects, outcome measures and experimental designs limits the possibilities of generalizing results as well as conducting meta-analytical research. Certain theoretical models of GAD describe our understanding of this disorder and form the basis for treatment interventions. However, fMRI research thus far has failed to validate these models. To bridge the gap between fundamental research and clinical practice in GAD, we propose that fMRI researchers make an effort to validate the existing cognitive model of GAD. An alternative approach could be that new models would be based on current neuroimaging research as well as convergent research methods such as Heart Rate Variability (a bottom up approach).

Abstract
BACKGROUND Generalized anxiety disorder (GAD) is one of the most common anxiety disorders in older people. Although GAD in older adults seems to differ in many aspects like clinical presentation, severity and treatment response, there is a paucity of comparative research. AIMS The aim of the study is to compare the clinical presentation of GAD between older and young adults. METHODS One hundred and two non-demented older patients (age ≥65) and 64 young patients (age <45) who were diagnosed with GAD according to the DSM-IV-TR criteria were included to the study. Socio-demographic Data Form, the Structured Clinical Interview for DSM Disorders-1 (SCID-1), the Questionnaire for the Suggested Behavioral Criteria of GAD for DSM-5, the Hamilton Depression Scale (HAM-D), the Generalized Anxiety Disorder Severity Scale (GADSS) and the Sheehan Disability Scale (SDS) were applied to both groups. RESULTS AND CONCLUSIONS Older GAD patients had more disturbances of sleep, less reassurance seeking behaviors, higher rates of depression and higher depression severity when compared to the young patients. Although older people seemed to have a lower severity of GAD, they had higher disability due to worries. Older patients worried more about their own health and family well-being, whereas young patients worried more about future and other's health.

Abstract
Generalized anxiety disorder (GAD) is a prevalent and highly disabling mental health condition; however, there is still much to learn with regard to pertinent biomarkers, as well as diagnosis, made more difficult by the marked and common overlap of GAD with affective and anxiety disorders. Recently, intensive research efforts have focused on GAD, applying neuroimaging, genetic, and blood-based approaches toward discovery of pathogenetic and treatment-related biomarkers. In this paper, we review the large amount of available data, and we focus in particular on evidence from neuroimaging, genetic, and neurochemical measurements in GAD in order to better understand potential biomarkers involved in its etiology and treatment. Overall, the majority of these studies have produced results that are solitary findings, sometimes inconsistent and not clearly replicable. For these reasons, they have not yet been translated into clinical practice. Therefore, further research efforts are needed to distinguish GAD from other mental disorders and to provide new biological insights into its pathogenesis and treatment.

Abstract
As a form of therapy, cognitive behavioral therapy (CBT) is more than a mere “toolbox.” CBT allows us to better understand how the human mind is functioning because it is based on neuroscience and experimental and scientific psychology. At the beginning, the Diagnostic and Statistical Manual of Mental Disorders (DSM) was “nontheoretical,” but nowadays (the most recent version being DSM-5), it is increasingly based on CBT paradigms (with the insertion of important notions such as cognitions and behaviors). This Brief Report presents what we currently know about generalized anxiety disorder (GAD) and how we can treat this condition by nonpharmaceutical means. In the last few years, GAD theories have evolved, becoming more precise about the cognitive functioning of GAD sufferers. Here, we look at current theoretical models and the main techniques of therapeutic care, as well as the advances in research about the “transdiagnostic” process and GAD in childhood. CBT is an effective treatment for GAD, typically leading to reductions in worry, and a study has shown that such therapy is equal to pharmaceutical treatment and more effective 6 months after study completion.

Abstract
INTRODUCTION Although generalized anxiety disorder (GAD) is common and disabling, there are few Canadian studies on this mental illness. We compared the characteristics, health status, health services use and health care needs of Canadians with GAD to those with depression. METHODS Data are from the 2012 Canadian Community Health Survey-Mental Health, which surveyed a nationally representative sample of Canadians aged 15 years and older (n = 23 709; response rate of 68.9%). The respondents we studied had selfreported symptoms compatible with GAD and/or major depressive episode (MDE) in the preceding 12 months (n = 1598). Estimates were weighted to represent the Canadian household population. We performed descriptive and multinomial multivariate logistic regression analyses. RESULTS In 2012, an estimated 700 000 (2.5%) Canadians aged 15 years and older reported symptoms compatible with GAD in the previous 12 months. MDE symptoms co-occurred in 50% of these individuals. Those with GAD only reported fair/poor perceived health (29.7%), moderate to severe psychological distress (81.2%) and moderate to severe disability (28.1%) comparable to (or even slightly worse) than those with MDE only (24.7%, 78.8% and 24.8% respectively). Those with comorbid GAD and MDE demonstrated the worst health outcomes; 47.3% of them reported fair/poor perceived health, 94.0% reported moderate to severe psychological distress and 52.4% reported moderate to severe disability. Nearly 50% of those with comorbid GAD and MDE reported that their need for health care was not met or only partially met, compared to about 30% of those with GAD or MDE only. CONCLUSION While GAD is associated with levels of distress and disability comparable to (or slightly worse) than those affected by MDE only, the health status of those with comorbid disease is significantly worse than those with GAD or MDE only. Improved diagnosis, screening for comorbidity and management are essential to minimize the impacts of this mental illness.

Abstract
Investigation for a possible anxiety disorder should be considered in patients with multiple or persistent anxiety symptoms or multiple somatic complaints without a clear somatic etiology. The ideal treatment for anxiety disorders is a combination of pharmacologic and behavioral strategies. As primary care health care evolves, it is expected that the management of mental health disorders (including anxiety disorders) will largely occur in the context of collaborative care models in which patients and primary care clinicians are assisted by trained case managers who help facilitate a more comprehensive, holistic treatment plan between primary care and mental health providers.

Abstract
BACKGROUND The preclinical results indicate that magnesium, an N-methyl-d-aspartate receptor (NMDAR) blocker has anxiolytic and antidepressant-like activity. One of the mechanisms involved in these activities is modulation of glutamate, γ-aminobutyric acid (GABA) system. Based on this, the aim of the present study was to investigate the effect of magnesium on the level of glutamic acid decarboxylase-67kDa (GAD-67) in the different brain areas in the chronic mild stress (CMS) and olfactory bulbectomy (OB) models of depression in rats. METHODS Magnesium (15mg/kg) was administered intraperitonealy once daily for 14 days in the OB model and for 35 days in the CMS model. 24h after the last dose, the prefrontal cortex (PFC), hippocampus and amygdala were collected and the GAD-67 protein level was determined by the western blotting method. RESULTS In the OB model, chronic magnesium treatment normalized decreased by OB protein level of GAD-67 in PFC. CMS did not influence the GAD-67 protein level, however magnesium increased GAD-67 protein expression in amygdala and PFC of stress rats when compared to vehicle-treated stress group. OB or CMS models as well as magnesium treatment did not affect GAD-67 protein level in the hippocampus. CONCLUSIONS Obtained results indicate that the antidepressant-like activity of magnesium in CMS and OB models of depression is associated with an enhanced expression of GAD-67 in the PFC and amygdala.

Abstract
Comorbidities associated with depression have been researched in a number of contexts. However, the epidemiological situation in clinical practice is understudied, especially in the post-Communist Central and Eastern Europe region. The aim of this study was to assess physical comorbidities in depression, and to identify whether there are increased odds of physical comorbidities associated with co-occurring depressive and anxiety disorders. Data on 4264 patients aged 18–98 were collected among medical doctors in the Czech Republic between 2010 and 2011. Descriptive statistics were calculated and multiple logistic regressions were performed to assess comorbidities among patients with depressive disorder. There were 51.29% of those who have a physical comorbidity, and 45.5% of those who have a comorbid anxiety disorders among patients treated with depression in Czech primary care. Results of logistic regressions show that odds of having pain, hypertension or diabetes mellitus are particularly elevated at those who have co-occurring depressive and anxiety disorder. Our findings demonstrate that comorbidities associated with depressive disorders are highly prevalent in primary health care practice, and that physical comorbidities are particularly frequent among those with co-occurring depressive and anxiety disorders.

Abstract
The existence of the nervous form of Chagas disease is a matter of discussion since Carlos Chagas described neurological disorders, learning and behavioural alterations in Trypanosoma cruzi-infected individuals. In most patients, the clinical manifestations of the acute phase, including neurological abnormalities, resolve spontaneously without apparent consequence in the chronic phase of infection. However, chronic Chagas disease patients have behavioural changes such as psychomotor alterations, attention and memory deficits, and depression. In the present study, we tested whether or not behavioural alterations are reproducible in experimental models. We show that C57BL/6 mice chronically infected with the Colombian strain of T. cruzi (150 days post-infection) exhibit behavioural changes as (i) depression in the tail suspension and forced swim tests, (ii) anxiety analysed by elevated plus maze and open field test sand and (iii) motor coordination in the rotarod test. These alterations are neither associated with neuromuscular disorders assessed by the grip strength test nor with sickness behaviour analysed by temperature variation sand weight loss. Therefore, chronically T. cruzi-infected mice replicate behavioural alterations (depression and anxiety) detected in Chagas disease patients opening an opportunity to study the interconnection and the physiopathology of these two biological processes in an infectious scenario.

Abstract
Introduction: This study examined the prevalence, clinical characteristics, help seeking patterns, and military experiences associated with past-year generalized anxiety disorder (GAD) using a representative sample of military personnel. Methods: Data were from the Canadian Community Health Survey–Canadian Forces Supplement ( n = 5,115 Regular Force, n = 3,286 Reserve Force), conducted by Statistics Canada on behalf of the Department of National Defence in 2002. GAD and other mental disorders were assessed using the World Mental Health Composite International Diagnostic Interview. Clinical features of GAD of interest included mean age of onset and episode length, symptoms, degree of impairment and co-occurring disorders, and perceived need for help and help seeking. Multivariate logistic regression models were conducted to examine the sociodemographic, military characteristics, and mental disorders correlated with past-year GAD. Results: Past-year and lifetime prevalence rates of GAD were 1.7% and 4.4%, respectively. The majority of military personnel with past-year GAD reported being severely impaired at work and in their relationships and social life. Those with past-year GAD, relative to those without it, had higher odds of having another mental disorder. Of military personnel with past-year GAD, 72.2% had sought help. Regular Force personnel, relative to reservists, had higher odds of having past-year GAD, as did individuals who witnessed atrocities. Discussion: GAD is modestly prevalent in the Canadian military and is associated with considerable functional impairment. Nevertheless, high rates of help seeking for GAD may speak to the availability, accessibility, and acceptability of mental health care in the Canadian Armed Forces.

Abstract
BACKGROUND AND OBJECTIVE Generalized anxiety disorder (GAD) is a psychiatric disorder characterized by excess worry and anxiety. GAD impacts overall health-related quality of life (HRQL), level of functioning, and disability. This literature review was conducted to understand the impact of pharmacological treatments on HRQL and functional outcomes. METHODS A literature review was conducted to identify randomized controlled trials (RCTs) comparing GAD pharmacological treatments with one or more patient-reported outcome (PRO) measure assessing HRQL, disability, functioning, or work productivity. Four databases were searched (PubMed, EMBASE, Cochrane Reviews, PsycInfo). Limits included English-language publications from 2004-2014. Abstracts and articles were reviewed to select articles reporting results of RCTs of pharmacological treatments for GAD that included one or more PRO measure. Article abstraction and summarization focused on key elements of the study design and PRO results. RESULTS One hundred sixty-three abstracts were reviewed; 44 articles were requested; 12 articles, representing 19 studies, were deemed relevant. The Sheehan Disability Scale (SDS) and the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) were the most frequently utilized PRO measures. In clinical trials with significant anxiety symptom reductions, the SDS and Q-LES-Q also improved with treatment and differentiated from placebo. Two trials included a measure of work productivity; both demonstrated significant improvements with short-term treatment. CONCLUSION Treatments that reduce anxiety symptoms are also associated with improvements in patient-reported HRQL, function, and disability. In addition to evaluation of treatment impacts on anxiety symptoms, clinical trials should include PRO measures of HRQL, disability, and functioning.

Abstract
Background While depression is a frequent psychiatric comorbid condition in diabetes and has significant clinical impact, the syndromal profile of depression and anxiety symptoms has not been examined in detail. Aims To determine the syndromal pattern of the depression and anxiety spectrum in a large series of patients with type 2 diabetes, as determined using a data-driven approach based on latent class analysis (LCA). Method Type 2 diabetes participants from the observational community-based Fremantle Diabetes Study Phase II underwent assessment of lifetime depression using the Brief Lifetime Depression Scale, the Patient Health Questionnaire 9-item version (PHQ-9) for current depression symptoms, and the Generalized Anxiety Disorder Scale that was specifically developed and validated for this study. The main outcome measure was classes of patients with a specific syndromal profile of depression and anxiety symptoms based on LCA. Results LCA identified four classes that were interpreted as “major anxious depression”, “minor anxious depression”, “subclinical anxiety”, and “no anxious depression”. All nine DSM-IV/5 diagnostic criteria for major depression identified a class with a high frequency of major depression. All symptoms of anxiety had similar high probabilities as symptoms of depression for the “major depression-anxiety” class. There were significant differences between classes in terms of history of depression and anxiety, use of psychoactive medication, and diabetes-related variables. Conclusions Patients with type 2 diabetes show specific profiles of depression and anxiety. Anxiety symptoms are an integral part of major depression in type 2 diabetes. The different classes identified here provide empirically validated phenotypes for future research.

Abstract
Anxiety disorders are the most common psychiatric condition presenting to primary care practitioners. Yet they can be easily overlooked or misdiagnosed. Patients that struggle with anxiety disorders are more likely to seek treatment from primary care providers than mental health specialists. Given the costs in terms of debilitation and associated financial burden, and increased risk of suicide, the identification and successful treatment of anxiety is imperative. By means of clinical acumen and the use of screening tools, the provider can develop expertise in recognition and effective treatment of anxiety disorders.

Abstract
Gamma-aminobutyric acid (GABA), a major inhibitory neurotransmitter in brain, is synthesized from glutamate and metabolized to succinic semialdehyde by glutamic acid decarboxylase (GAD) and GABA transaminase (GABA-T), respectively. The fast inhibitory effect of GABA is mediated by GABA type A (GABAA) receptors that are associated with several neurological disorders, and GABAA receptors are targets of several therapeutic agents. To date, information on the distribution and quantity of GABAA receptors in Carassius auratus gibelio is still limited. We investigated for the first time, the tissue-specific distribution of GABAARβ2a and GABAARβ2b, the two subunits of the predominant GABAA receptor subtype (α1β2γ2), and then, the expression of GABAARβ2a, GABAARβ2b, GAD, and quantified GABA-T genes in different tissues by quantitative real-time PCR method and compared different expressions between two developmental stages of C. auratus gibelio. Results showed that GABAARβ2a and GABAARβ2b genes expressed in both brain and peripheral organs using reverse transcription-polymerase chain reaction. In addition, the majority of GABAARβ2a, GABAARβ2b, GAD, and GABA-T were mainly synthesized in brain; however, a considerable amount of GABA-T was secreted from the peripheral tissues, especially in the liver. Moreover, the expression of GABAARβ2a and GABAARβ2b genes in different tissues varied with body weight change. This study provides a reference for further studies on GABA and GABAA receptors subunits and an insight on the possible pharmacological properties of the GABAA receptor in C. auratus gibelio.

Abstract
The Generalized Anxiety Disorder Inventory is a recently developed self-report measure that assesses symptoms of generalized anxiety disorder. Its psychometric properties have not been investigated further since its original development. The current study investigated its psychometric properties in a Canadian student/community sample. Exploratory principal component analysis replicated the original three-component structure. The total scale and subscales demonstrated excellent internal consistency reliability (α = 0.84-0.94) and correlated strongly with the Penn State Worry Questionnaire (r = 0.41-0.74, all ps <0.001) and Generalized Anxiety Disorder-7 (r = 0.55-0.84, all ps <0.001). However, only the total scale and cognitive subscale (r = 0.48-0.49, all ps <0.05) significantly predicted generalized anxiety disorder diagnosis established by diagnostic interview. The somatic subscale in particular may require revision to improve predictive validity. Revision may also be necessary given changes in required somatic symptoms for generalized anxiety disorder diagnostic criteria in more recent versions of the Diagnostic and Statistical Manual of Mental Disorders (i.e. although major changes occurred from Diagnostic and Statistical Manual of Mental Disorders-III-R to Diagnostic and Statistical Manual of Mental Disorders-IV, changes in Diagnostic and Statistical Manual of Mental Disorders-5 were minimal) and the possibility of changes in the upcoming 11th revision of the International Classification of Diseases.

Abstract
OBJECTIVE Today, there are many pharmacotherapeutic options for generalized anxiety disorder (GAD). The question is, which is the best medication for a particular patient at a particular moment? This is especially challenging because GAD is by definition a chronic disorder and new interventions should learn from earlier experiences. An algorithm which can help to use pretreatment information for drug selection is the "Pretreatment - Next Treatment (PN) - Algorithm". This article introduces an PN-algorithm for GAD. METHODS AND RESULTS For the development of a GAD-specific PN-algorithm, all possible pharmacological options for GAD are reviewed and brought into a rank order on the basis of scientific evidence regarding efficacy, tolerability, or price: (1) pregabalin, (2) venlafaxine XR, (3) selective serotonin reuptake inhibitors, (4) tricyclic antidepressants, (5) buspirone, (6) antipsychotics, (7) benzodiazepines, and (8) hydroxyzine. Based on this hierarchy and patient-specific information, a decision algorithm is derived, which allows to assess and evaluate pretreatment and to select the drug with no contraindications, limited negative or convincing positive effects, or the option which has not been used so far but which is the next compound in the hierarchy. CONCLUSIONS The "PN-GAD-algorithm" can be easily translated into a checklist to support clinical decision-making. It can also help to increase patient empowerment and cooperation in long-term treatment.

Abstract
The Revised Children’s Manifest Anxiety Scale (RCMAS) is regularly used with South African children, although its performance in this context has yet to be empirically evaluated. This study assessed the basic psychometric properties of the RCMAS using data collected in a large study examining the mental health of children and adolescents living in poor urban communities around Cape Town. Reliability of the full-scale was good, and the predicted relationships between anxiety, depression, PTSD, delinquency, age, sex, and somaticism scores offered evidence of construct validity. However, the reliabilities for the physiological, worry/oversensitivity, and concentration subscales were low, and confirmatory factor analysis revealed the hypothesized three-factor model did not adequately fit the data. Exploratory analyses suggested a four-factor solution consisting of social evaluation, worry, affective responses, and physiological symptoms/sleep disturbance factors. Further confirmatory research examining this four-factor structure is needed. Given the continued use of the RCMAS in South Africa, these findings provide an important first step in establishing its reliability and validity for use with South African youth; however, scores obtained on the three subscales should be interpreted with caution and further detailed psychometric evaluation of the RCMAS in South African samples is clearly required.

Abstract
OBJECTIVE This review aims to summarize meta-analyses and other relevant data relating to the efficacy and safety of the various treatment options for generalized anxiety disorder (GAD) in Europe. In addition, it will provide an overview of the prevalence, burden, and recognition of the disorder, with a view to raise awareness of GAD and inform primary care practitioners. RESEARCH DESIGN AND METHODS Relevant research or review articles on psychological or pharmacological treatments for GAD published in the English language between March 2006 and March 2012 were identified via a literature search in PubMed and ISI Web of Knowledge and from the Cochrane Library. Other relevant references/clinical guidelines were individually selected by the authors. RESULTS Prevalence rates of GAD vary across Europe but its economic and social burden is increasing. A large proportion of patients with GAD present with symptoms in primary care. However, due to the disorder's complexity and the incidence of comorbid diseases, some primary care physicians may lack the knowledge or confidence to effectively recognize, manage, and/or treat the disorder. This is despite psychological and pharmacological treatments being available for the effective management of GAD. CONCLUSIONS GAD remains a difficult disorder to detect and comorbid complications add to its economic and social burden. Early detection and intervention reduces the societal burden and improves GAD patients' quality of life and functional ability. Primary care practitioners play a key role in identifying and treating patients with GAD.

Abstract
OBJECTIVE The main aim of the present research was to evaluate the coherence of generalized anxiety disorder (GAD) psychopathological pattern, the robustness of its diagnostic criteria, and the clinical utility of considering this disorder as a discrete condition rather than assigning it a dimensional value. METHOD The study was designed in a purely naturalistic setting and carried out using a community sample; data from the Sesto Fiorentino Study were reanalyzed. RESULTS Of the 105 subjects who satisfied the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for the diagnosis of GAD, only 18 (17.1%) had no other comorbid DSM-IV disorder. The most frequent comorbid condition was major depressive disorder (70.4 %). Only 2 of the GAD diagnostic symptoms (excessive worry and muscle tension) showed a specific association with the diagnosis itself, whereas the others, such as feeling wound up, tense, or restless, concentration problems, and fatigue, were found to be more prevalent in major depressive disorder than in GAD. CONCLUSION Our study demonstrates that GAD, as defined by DSM-IV criteria, shows a substantial overlap with other DSM-IV diagnoses (especially with mood disorders) in the general population. Furthermore, GAD symptoms are frequent in all other disorders included in the mood/anxiety spectrum. Finally, none of the GAD symptoms, apart from muscle tension, distinguished GAD from patients without GAD.

Abstract
This article reviews the main issues associated with the concept and the diagnosis of generalized anxiety disorder (GAD) and examines the proposed DSM-5 diagnostic criteria for GAD. The lack of specific features, which is the primary issue for GAD, will not be addressed in DSM-5. The hallmark of the condition will remain pathological worry, although it also characterizes other disorders. Likewise, the proposed behavioral diagnostic criteria lack specificity for GAD, and it is not clear how these will be assessed. The proposed changes will lower the diagnostic threshold for GAD in DSM-5. Although this will not necessarily lead to a better recognition of GAD and an improvement in the perception of its relevance and clinical utility, many currently subthreshold cases will qualify for this diagnosis. The likely inclusion of many such "false-positives" will result in an artificial increase in the prevalence of GAD and will have further negative consequences.

Abstract
BACKGROUND We evaluated the effects of once-daily extended-release quetiapine fumarate (quetiapine XR) on patient-reported outcomes in generalized anxiety disorder (GAD). METHODS This is a report of a pooled analysis from three acute 8-week, randomized, placebocontrolled, fixed-dose (50, 150, 300 mg/day) studies and a 52-week maintenance flexible dose (50-300 mg/day) study of quetiapine XR monotherapy in patients with GAD. Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF) percent maximum total scores (items 1-14), item 15 ("satisfaction with medication"), item 16 ("overall life satisfaction"), and Pittsburgh Sleep Quality Index (PSQI) global scores are reported. Sheehan Disability Scale (SDS) total scores were also assessed (maintenance study only). RESULTS The acute studies showed significant improvements at week 8 in Q-LES-Q-SF percent maximum total score with quetiapine XR 150 mg/day (P < 0.001) and item 16 with quetiapine XR 50 (P < 0.05) and 150 mg/day (P < 0.001) versus placebo; PSQI global scores significantly improved with quetiapine XR 50, 150, and 300 mg/day versus placebo (P < 0.001). The maintenance study showed significant benefits versus placebo with quetiapine XR 50-300 mg/day in Q-LES-Q-SF percent total score, item 15 and item 16 scores, PSQI global score, and SDS total score. CONCLUSION Quetiapine XR 150 mg/day (acute studies) and 50-300 mg/day (maintenance study) improved quality of life, overall functioning, and sleep quality in patients with GAD.

Abstract
PURPOSE To investigate medication use, direct healthcare costs and comorbidities in patients with generalised anxiety disorder (GAD) within specialised care in Sweden 2006-2007. METHODS A retrospective study was conducted using data from the National Patient Register and the Swedish Prescribed Drug Register. All patients with a primary GAD (ICD-10) diagnosis in 2006 were followed for 12 months to study medication use and health care consumption. Resource use was evaluated from the number of hospitalisation episodes, number of visits to outpatient care and medication dispensed. Costs were calculated by multiplying the number of visits and hospitalisation episodes with the corresponding unit costs. Descriptive statistics were used for all analyses. RESULTS Three thousand seven hundred and one patients with a primary GAD diagnosis were included in the study. Thirty-four percent of the patients (n=1246) had at least one secondary comorbid diagnosis. SSRIs/SNRIs were the most commonly dispensed medications, followed by benzodiazepine-anxiolytics, hypnotics and antihistamines. The mean number of treatment days for all medications prescribed and dispensed was highest (1144 days) for elderly women aged 65 years or more (treatment days per patient could exceed 365 days due to multiple concomitant medication use). Elderly patients were frequently prescribed benzodiazepine-anxiolytics (n=92/117 men [79%]; n=238/284 women [84%]) and hypnotics (n=70 men [60%]; n=178 women [63%]) compared to the overall study population (n=612/1303 men [47%] and n=935/2398 women [39%], respectively). GAD-related direct costs accounted for 96% of all direct costs. Mean number of hospitalisation days and corresponding costs were high (19 days; SEK 92,156; n=358 [9.7%]) in relation to medication (SEK 5520; n=3352 [91%]) and outpatient costs (SEK 7698; n=3461 [94%]). CONCLUSIONS The high rate of polypharmacy, significant psychiatric comorbidity and widespread use of benzodiazepine-anxiolytics and medications not indicated for GAD suggest that the disease burden is high. Total direct costs associated with the disease were high but still likely to be underestimated.

Abstract
The present article focused on the problem of validity, reliability and specificity of psychiatric diagnoses.The authors moved by the concept of syndrome, defined by Sydenham in the 18th century as a constellation of several interrelated symptoms, showing a stable, characteristic structure and a peculiar prognosis, in order to analyse the peculiarity of the current psychiatric nosology. In our opinion, the current nosographic system based on DSM-IV criteria, prevents psychiatry from benefiting of the significant technological progress that has led the rest of medical sciences to important clinical achievements in the last 20 years. The case of Generalized Anxiety Disorder was taken as an example of a disease characterized by unstable diagnostic criteria, high rate of comorbidity and uncertain boundaries. An analysis of the data from the Sesto Fiorentino study was performed to investigate the presence of common mood and anxiety symptoms across the most represented DSM IV diagnoses, in order to evaluate the specificity of these symptoms.The results supported the hypothesis of a low specificity of these symptoms, suggesting the need for psychiatry to find new and more specific markers and instruments.

Abstract
BACKGROUND Prior imaging studies have shown structural, functional and biochemical impairments in patients with generalized anxiety disorder (GAD), particularly in the right hemisphere. In this study we investigated, for the first time to the best of our knowledge, the white-matter microstructure organization in GAD. METHOD A total of 12 patients with DSM-IV GAD and 15 matched healthy controls underwent a magnetic resonance imaging session of diffusion weighted imaging, exploring white-matter water molecules by the means of apparent diffusion coefficients (ADCs). Regions of interests were placed in the frontal, parietal, temporal and occipital lobes and in the splenium and genu of the corpus callosum, bilaterally. RESULTS ADC measures were significantly greater in patients with GAD in the right splenium and right parietal cortex compared with healthy controls (p⩽0.002). No significant correlations between ADCs and age or clinical variables were found. CONCLUSIONS We provide evidence that GAD is associated with disrupted white-matter coherence of posterior right hemisphere regions, which may partly sustain the impaired cognitive regulation of anxiety. Future diffusion imaging investigations are expected to better elucidate the communication between the parietal cortex and other right hemisphere regions in sustaining the cognitive processing of social and emotional stimuli in patients with GAD.

Abstract
Serotonin is a major neurotransmitter and affects various functions both in the brain and in the rest of the body. It has been demonstrated that altered serotinergic function is implicated in various psychiatric disorders including depression and schizophrenia. Serotonin has also been implicated along with dopamine in attention deficit-hyperkinetic disorder (AD-HKD). This study provides a versatile validated method for the analysis of serotonin, hydroxyindole acetic acid and dopamine in urine using LC-MS/MS. This method was then used to quantify these analytes in a test group of 17 children diagnosed with severe AD-HKD. This group was compared to a matched control group to investigate the possibility that one of these compounds may be a potential biomarker for this condition. The developed method provided good linear calibration curves for the multiplex assay of analytes in urine (0.05-3.27 nmol/L; R(2) ≥ 0.9977). Acceptable inter-day repeatability was achieved for all analytes with RSD values (n = 9) ranging from 1.1% to 9.3% over a concentration range of 0.11-3.27 μmol/L in urine. Excellent limits of detection (LOD) and limits of quantitation (LOQ) were achieved with LODs of 8.8-18.2 nmol/L and the LOQs of 29.4-55.7 nmol/L for analytes in urine. Recoveries were in the ranges of 98-104%, 100-106% and 91-107% for serotonin, 5-HIAA and dopamine, respectively. An appropriate sample clean-up procedure for urine was developed to ensure efficient recovery and reproducibility on analysis. Evaluation of matrix effects was also carried out and the influence of ion suppression on analytical results reported. Confirmatory analysis was carried out on a linear trap quadrupole-Orbitrap mass spectrometer to obtain high mass accuracy data of the target analytes in the clinical samples.

Abstract
Generalized anxiety disorder (GAD) is a prevalent and disabling disorder characterised by persistent worrying, anxiety symptoms, and tension. General practitioners and mental healthcare professionals frequently misdiagnose the presenting symptoms. This article addresses the clinical presentation of GAD and provides guidelines for discriminating GAD from other disorders, based on theoretical considerations and clinical experience. Debate relating to the validity of the definition of GAD is discussed, and suggestions are made for improving the criteria for GAD, which may guide future versions of classification systems such as the Diagnostic and Statistical Manual.

Abstract
This study examined the impact of comorbidity on treatment outcome and the effects of cognitive behavioral therapy (CBT) for anxiety and depressive disorders on comorbid disorders in a naturalistic sample of 150 patients presenting to an anxiety disorders clinic. The following results were observed across principal (i.e., most severe) diagnoses. Patients with comorbid anxiety and depressive disorders presented for treatment with higher severity of their principal disorder than patients without comorbidity. However, the presence of comorbidity did not predict dropout or poor treatment response, and patients demonstrated significant improvement in their principal disorders regardless of comorbidity. The frequency of clinically severe and subclinical (i.e., not severe enough to meet diagnostic criteria) comorbid conditions decreased significantly over the course of treatment. The implication of these findings for the classification and treatment of emotional disorders is discussed.

Davidson JRT, Feltner DE, Dugar A. Management of generalized anxiety disorder in primary care: identifying the challenges and unmet needs. PRIMARY CARE COMPANION TO THE JOURNAL OF CLINICAL PSYCHIATRY 2010; 12. [PMID: 20694114 DOI: 10.4088/pcc.09r00772blu] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2008] [Accepted: 04/24/2009] [Indexed: 10/19/2022]
Abstract
BACKGROUND Generalized anxiety disorder (GAD) is one of the most common psychiatric disorders in primary care, although it is often underrecognized and undertreated. GAD is chronic, disabling, and associated with other health problems. Treatment response is often unsatisfactory, but the clinical evidence base for new treatments has expanded substantially in the past decade and suggests a growing range of options for reducing the burden of GAD. The objective of this article was to review current literature on GAD and its management to provide an overview of the clinical importance of GAD in primary care and available treatments. DATA SOURCES Recent studies (ie, over the past decade) on the epidemiology and treatment of GAD were identified by searching Medline using the term generalized anxiety disorder only and in combination with the terms epidemiology and treatment and for each drug class (benzodiazepines, azapirones, antidepressants, antihistamines, alpha-2-delta ligands, and antipsychotics) and for named drugs (buspirone, venlafaxine, duloxetine, fluoxetine, escitalopram, olanzapine, paroxetine, pregabalin, quetiapine, and risperidone in addition to psychological therapies and cognitive-behavioral therapy. The literature search was conducted in August 2008 for the period 1987-2009. STUDY SELECTION Studies were included if judged to be relevant to a review of the epidemiology and management of GAD. Articles were excluded if they were not written in English or were published more than 10 years before the literature search was conducted. A few older studies were included for which more recent research evidence was not available. Recent national and international guidelines for the management of GAD were also reviewed. DATA EXTRACTION/SYNTHESIS Most currently available interventions have similar overall efficacy, and treatment choices should reflect the situation of individual patients. Important unmet needs exist for treatments (1) that work rapidly, with (2) broad spectrum benefits, (3) that can improve rates of remission and well-being, (4) are devoid of risk for withdrawal symptoms, and (5) have few if any adverse interactions with other drugs. Additional needs include (6) safer drugs for the elderly, (7) safe and effective drugs for children with GAD, (8) further evaluation of psychotherapy, and (9) understanding the appropriate circumstances for, and optimal choices of, drug combination. CONCLUSION While the development of novel treatments evolves, current management approaches can focus on improving identification and defining optimal use of available therapies for GAD.

BIOCHIMICA ET BIOPHYSICA ACTA 2010; 1798:1002-7. [PMID: 20056107 DOI: 10.1016/j.bbamem.2009.12.021] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2009] [Revised: 12/17/2009] [Accepted: 12/22/2009] [Indexed: 11/23/2022]
Abstract
GABArho1 receptors are formed by homopentameric assemblies that gate a chloride ion-channel upon activation by the neurotransmitter. Very little is known about the structural and functional roles played by the different domains that form each subunit; but one of them, the fourth transmembrane segment (TM4), is known to form a hydrophobic bundle together with three other TM segments that are necessary to stabilize the structure of the receptor. In this study we progressively removed amino acid residues from the C-terminus of the human GABArho1 and studied the functional properties of the receptor mutants expressed in X. laevis oocytes. We found that deletions of up to the last four residues gave rise to receptors that were still functional, generating currents of 3.92 microA for the wt, 5.75 microA for S479X, 1.82 microA for F478X, 0.52 microA for I477X and 0.27 microA for S476X when exposed to 5 microM GABA; surprisingly, the mutant with one residue removed resulted more sensitive to the agonists. Further deletions, up to residue W475, resulted in receptors that did not gate an ion-channel. In addition, deleting the signal sequence, from R2-A15, in the N-terminus produced non-functional receptors. This study reveals that GABArho1 can tolerate removal of several residues that form the fourth transmembrane segment up to a critical point, signaled by W475, beyond which the mutant protein is translated but does not form functional receptors. A comparative study is presented of some electrophysiological and pharmacological properties of the deletion mutants that were able to generate GABA currents.
