Evaluating the benefits of a youth mental health curriculum for students in Nicaragua: a parallel-group, controlled pilot investigation.

BACKGROUND: High rates of mental illness and addictions are well documented among youth in Nicaragua. Limited mental health services, poor mental health knowledge and stigma reduce help-seeking. The Mental Health Curriculum (MHC) is a Canadian school-based program that has shown a positive impact on such contributing factors. This pilot project evaluated the impact of the MHC on mental wellness and functioning among youth in Leon, Nicaragua. METHODS: High school and university students (aged 14-25 years) were assigned to intervention (12-week MHC; n  =  567) and control (wait-list; n  =  346) groups in a non-randomized design. Both groups completed measures of mental health knowledge, stigma and function at baseline and 12 weeks. Multivariate analyses and repeated measures analyses were used to compare group outcomes. RESULTS: At baseline, intervention students showed higher substance use (mean difference [MD]  =  0.24) and lower perceived stress (MD = -1.36) than controls (p  <  0.05); there were no other group differences in function. At 12 weeks, controlling for baseline differences, intervention students reported significantly higher mental health knowledge (MD  =  1.75), lower stigma (MD  =  1.78), more adaptive coping (MD  =  0.82), better lifestyle choices (MD  =  0.06) and lower perceived stress (MD = -1.63) (p  <  0.05) than controls. The clinical significance as measured by effect sizes was moderate for mental health knowledge, small to moderate for stigma and modest for the other variables. Substance use also decreased among intervention students to similar levels as controls (MD  =  0.03) (p > 0.05). CONCLUSIONS: This pilot investigation demonstrates the benefits of the MHC in a low-and-middle-income youth population. The findings replicate results found in Canadian student populations and support its cross-cultural applicability.

Depression, anxiety, and post-traumatic stress disorder among youth in low and middle income countries: A review of prevalence and treatment interventions.

BACKGROUND: Low and middle income countries (LMICs) not only have the majority of the world's population but also the largest proportion of youth. Poverty, civil conflict and environmental stressors tend to be endemic in these countries and contribute to significant psychiatric morbidity, including depression, anxiety and post-traumatic stress disorder (PTSD). However, mental health data from LMICs is scarce, particularly data on youth. Evaluation of such information is crucial for planning services and reducing the burden of disability. This paper reviews the published data on the prevalence and randomized trials of interventions for depression, anxiety and PTSD in youth in LMICs. METHODS: PubMed and Google Scholar were searched for articles published in English up to January 2017, using the keywords: Low/middle income country, depression, anxiety, post-traumatic stress disorder, child, youth, adolescent, prevalence, treatment, intervention, and outcomes. RESULTS: The few prevalence studies in LMICs reported rates of up to 28% for significant symptoms of depression or anxiety among youth, and up to 87% for symptoms of PTSD among youth exposed to traumatic experienences, though these rates varied widely depending on several factors, including the assessments tools used. Most rigorous interventions employed some form or variation of CBT, with mixed results. Studies using other forms of psychosocial interventions appear to be heterogeneous and less rigorous. CONCLUSIONS: The mental health burden due to depression and anxiety disorders in youth is substantial in LMICs, with high needs but inadequate services. Youth specific services for early detection and cost-effective interventions are needed.

Coping strategies used by traumatic spinal cord injury patients in Sri Lanka: a focus group study.

PURPOSE: Psychosocial consequences of traumatic spinal cord injury (SCI) have been well documented in Western populations, but there is no published literature on such incidence in the Sri Lankan population. The purpose of this study was to explore the psychosocial impact of SCI in a Sri Lankan population and to examine this population's coping mechanisms. METHODS: Participants were recruited purposively at the Ragama Rheumatology and Rehabilitation Hospital, the sole rehabilitation facility for SCI patients in Sri Lanka. Focus groups were conducted with 23 consenting individuals. Interview transcripts were analysed using descriptive thematic analysis. RESULTS: Four domains of life impact, three types of active coping strategies and four types of external supports were identified. Decreased ambulation and burden on family life were significant concerns for male and female participants alike. Religious practices were reported most frequently as active coping strategies, followed by positive reframing and goal-setting. Reported external supports included guided physiotherapy, informational workshops, social support and peer networks. CONCLUSION: Rehabilitation efforts for Sri Lankan SCI patients should be sensitive to psychosocial concerns in addition to physical concerns in order to help patients re-integrate into their family lives and community. Furthermore, religious practices should be respected as possible aids to rehabilitation. Implications for Rehabilitation Rehabilitative efforts should be conscientious of patients' psychosocial well-being in addition to their physical well-being. Hospital-based rehabilitative efforts for traumatic spinal cord injury patients should promote functional independence and community re-integration. Spiritual and/or religious practices should be respected as ways by which traumatic spinal cord injury patients may confront personal challenges that arise following injury.

Contribution of sex hormones to gender differences in schizophrenia: A review.

Female patients with schizophrenia tend to have a more benign course and better outcomes than males. One proposed explanation is the differential influence of male and female sex hormones, including estrogen, progesterone, testosterone, and dehydroepiandrosterone (DHEA) and its sulfate (DHEAS). Such benefit may be mediated by their effects on neurotransmitters and neuroprotection. Besides altered estrogen and DHEA/DHEAS levels in female patients, data is equivocal on hormonal differences between patients and controls. However, several reports note a mostly negative correlation between estrogen levels and symptom severity in both genders, and a positive correlation between estrogen levels and neurocognition but mainly in females. Adjunctive estrogen appears to improve symptoms in both genders. Progesterone levels have inconsistent links to symptom severity in both genders, and correlate positively with neurocognition but only in males. Estrogen-progesterone combination shows preliminary benefits as augmentation for both symptoms and neurocognition in females. Testosterone levels correlate inversely with negative symptoms in males and have inconsistent associations with neurocognition in both genders. Testosterone augmentation reduced negative symptoms in male patients in a pilot investigation, but has not been evaluated for neurocognition in either gender. DHEA/DHEAS have mixed results for their association with, and clinical utility for, symptoms and neurocognition in both genders. Overall, data on the impact of sex hormones on clinical course or as treatment for schizophrenia is limited, but estrogen has most evidence for positive influence and clinical benefit. The possibly greater tolerability and broader impact of these hormones versus existing medications support further exploration of their use.

Comparative efficacy, acceptability, and tolerability of augmentation agents in treatment-resistant depression: systematic review and network meta-analysis.

OBJECTIVE: To comparatively analyze the efficacy, acceptability, and tolerability of various augmentation agents in adult patients with treatment-resistant depression. DATA SOURCES: An electronic literature search of PubMed, EMBASE, the Cochrane Library, Web of Science, EBSCO, PsycINFO, EAGLE, and NTIS for trials published up to December 2013 was conducted. Several clinical trial registry agencies and US Food and Drug Administration reports were also reviewed. No language, publication date, or publication status restrictions were imposed. STUDY SELECTION: Randomized controlled trials comparing 11 augmentation agents (aripiprazole, bupropion, buspirone, lamotrigine, lithium, methylphenidate, olanzapine, pindolol, quetiapine, risperidone, and thyroid hormone) with each other and with placebo for adult treatment-resistant depression were included. DATA EXTRACTION: The proportion of patients who responded to treatment was defined as primary efficacy, and the proportion of all-cause discontinuation and side-effects discontinuation were respectively defined as acceptability and tolerability, which were assessed with odds ratios (ORs) and a Bayesian random-effects model with 95% credible intervals (CrIs). RESULTS: A total of 48 trials consisting of 6,654 participants were eligible. In terms of the primary efficacy, quetiapine (OR = 1.92; 95% CrI, 1.39-3.13), aripiprazole (OR = 1.85; 95% CrI, 1.27-2.27), thyroid hormone (OR = 1.84; 95% CrI, 1.06-3.56), and lithium (OR = 1.56; 95% CrI, 1.05-2.55) were significantly more effective than placebo. Sensitivity analyses indicated that efficacy estimates for aripiprazole and quetiapine were more robust than those for thyroid hormone and lithium. In terms of acceptability, no significant difference was found between active agents and placebo. In terms of tolerability, compared to placebo, quetiapine (OR = 3.85; 95% CrI, 1.92-8.33), olanzapine (OR = 3.36; 95% CrI, 1.60-8.61), aripiprazole (OR = 2.51; 95% CrI, 1.11-7.69), and lithium (OR = 2.30; 95% CrI, 1.04-6.03) were significantly less well tolerated. CONCLUSIONS: Quetiapine and aripiprazole appear to be the most robust evidence-based options for augmentation therapy in patients with treatment-resistant depression, but clinicians should interpret these findings cautiously in light of the evidence of potential treatment-related side effects.

Complementary and alternative therapies as add-on to pharmacotherapy for mood and anxiety disorders: a systematic review.

BACKGROUND: Depressed and anxious patients often combine complementary and alternative medicine (CAM) therapies with conventional pharmacotherapy to self-treat symptoms. The benefits and risks of such combination strategies have not been fully evaluated. This paper evaluates the risk-benefit profile of CAM augmentation to antidepressants in affective conditions. METHODS: PubMed was searched for all available clinical reports published in English up to December 2012. Data were evaluated based on graded levels of evidence for efficacy and safety. RESULTS: Generally, the evidence base is significantly larger for depression than for anxiety disorder. In unipolar depression, there is Level 2 evidence for adjunctive sleep deprivation (SD) and Free and Easy Wanderer Plus (FEWP), and Level 3 for exercise, yoga, light therapy (LT), omega-3 fatty acids, S-adenosylmethionine and tryptophan. In bipolar depression, there is Level 1 evidence for adjunctive omega-3s, Level 2 for SD, and Level 3 for LT and FEWP. In anxiety conditions, exercise augmentation has Level 3 support in generalized anxiety disorder and panic disorder. Though mostly well-tolerated, these therapies can only be recommended as third-line interventions due to the quality of available evidence. LIMITATIONS: Overall, the literature is limited. Studies often had methodological weaknesses, with little information on long-term use and on potential drug-CAM interactions. Many CAM studies were not published in English. CONCLUSIONS: While several CAM therapies show some evidence of benefit as augmentation in depressive disorders, such evidence is largely lacking in anxiety disorders. The general dearth of adequate safety and tolerability data encourages caution in clinical use.

Paroxetine in the treatment of dysthymic disorder without co-morbidities: A double-blind, placebo-controlled, flexible-dose study.

Few published studies have evaluated selective serotonin reuptake inhibitors in dysthymia without current co-morbid major depression. In this 12-week study, 40 dysthymic patients were randomly assigned to either placebo (n=19) or 20-40 mg/day of paroxetine (n=21). At endpoint, the paroxetine group showed significantly greater improvement on the Clinical Global Impression Scale, Beck Depression Inventory, and Quality of Life Enjoyment and Satisfaction Questionnaire (p<0.05), and a trend to superiority over placebo on the Hamilton Depression Rating Scale. Response and remission were significantly higher with paroxetine than placebo (p<0.05). There were no significant differences in drop out rates or frequency of adverse effects, except for excessive sweating (greater with paroxetine, p=0.04). Reporting of multiple side effects was also higher with paroxetine than with placebo (p=0.02). Paroxetine is more effective than placebo in improving symptoms and quality of life in dysthymia, and is generally tolerable.

Obsessive-compulsive spectrum disorders: a review of the evidence-based treatments.

OBJECTIVE: To provide a review of the evidence-based treatments for obsessive-compulsive spectrum disorders (OCSD), a group of conditions related to obsessive-compulsive disorder (OCD) by phenomenological and etiological similarities, the morbidity of which is increasingly recognized. METHOD: Literature relating to the following disorders: body dysmorphic disorder, hypochondriasis, trichotillomania, onychophagia, psychogenic excoriation, compulsive buying, kleptomania, and pathological gambling, and published between January 1965 and October 2007, was found using PubMed. Included in this review were 107 treatment reports. RESULTS: Serotonin reuptake inhibitors (SRIs) have shown benefits as first-line, short-term treatments for body dysmorphic disorder, hypochondriasis, onychophagia, and psychogenic excoriation, with some benefits in trichotillomania, pathological gambling, and compulsive buying. There are also suggested benefits for several atypical antipsychotics in disorders with a high degree of impulsivity, including trichotillomania and pathological gambling, and to a lesser extent, kleptomania and psychogenic excoriation. Cognitive-behavioural interventions have generally shown evidence for use as first-line treatment across the spectrum, with some variability in degree of benefit. CONCLUSIONS: As in OCD, several conditions in the proposed OCSD benefit from SRIs and (or) cognitive-behavioural interventions. However, the treatment literature is generally limited, and more randomized controlled trials (RCTs) are needed to evaluate individual and combination treatments, for short-term use and as maintenance.

Yoga in the treatment of mood and anxiety disorders: A review.

BACKGROUND: Patient use of complementary and alternative treatments, including yoga, to manage mood and anxiety disorders, has been well documented. Despite research interest, there are few recent reviews of the evidence of the benefit of yoga in these conditions. METHOD: The PubMed, Medline and PsycInfo databases were searched for literature published up to July 2008, relating to yoga and depressive and anxiety disorders. RESULTS: The paucity of reported studies and several methodological constraints limit data interpretation. In depressive disorders, yoga may be comparable to medication and the combination superior to medication alone. There is reasonable evidence for its use as second-line monotherapy or augmentation to medication in mild to moderate major depression and dysthymia, with early evidence of benefit in more severe depression. In anxiety disorders, yoga may be superior to medication for a subgroup of patients, but its benefits in specific conditions are still largely unknown. Second-line monotherapy is indicated in performance or test anxiety, but only preliminary evidence exists for obsessive-compulsive disorder and post-traumatic stress disorder. Yoga appears to be superior to no treatment and progressive relaxation for both depression and anxiety, and may benefit mood and anxiety symptoms associated with medical illness. It shows good safety and tolerability in short-term treatment. CONCLUSION: Reasonable evidence supports the benefit of yoga in specific depressive disorders. The evidence is still preliminary in anxiety disorders. Given its patient appeal and the promising findings thus far, further research on yoga in these conditions is encouraged.

Novel uses for risperidone: focus on depressive, anxiety and behavioral disorders.

Risperidone has been shown to be a safe and effective atypical antipsychotic agent. It was initially approved for the treatment of schizophrenia, and now, in many countries, is used to treat other conditions, including bipolar disorder, dementia and behavior problems in a range of age groups. Yet, frequent off-label use by clinicians to treat other mood and anxiety disorders and behavioral disorders is common and requires an examination of the risks and benefits in such populations. A review of the literature provides varying levels of evidence supporting its use in a range of depressive and anxiety disorders, and in special populations, including children and the elderly. Most reports are based on short-term studies and include its use both as monotherapy and as an augmenting agent to other psychotropics, and in a range of doses. Further randomized controlled trials are needed to confirm the efficacy and tolerability of risperidone, both short- and long-term, in many of these conditions. The published evidence is summarized, with recommendations and suggestions for its use.
