title: Lithium safety and tolerability in mood disorders: a critical review

description: Background : Lithium is a first-line treatment for bipolar disorder in all phases, also indicated as add-on drug for unipolar depression and suicide prevention. This study encompasses a broad critical review on the safety and tolerability of lithium for mood disorders. Methods : A computerized search for English written human studies was made in MEDLINE, using the keywords “lithium” and “mood disorders”, starting from July 1993 through July 2013 (n = 416). This initial search aimed to select clinical trials, prospective data, and controlled design studies of lithium treatment for mood disorders reporting adverse effects (n = 36). The final selection yielded 91 studies. Results : The most common general side effects in patients on lithium treatment were thirst, frequent urination, dry mouth, weight gain, fatigue and cognitive complaints. Lithium users showed a high prevalence of hypothyroidism, hyperparathyroidism, and decrease in urinary concentration ability. Reduction of glomerular filtration rate in patients using lithium was also observed, but in a lesser extent. The evidence of teratogenicity associated with lithium use is not well established. Anti-inflammatory non-steroidal drugs, thiazide diuretics, angiotensin-converting enzyme inhibitors, and alprazolam may increase serum lithium and the consequent risk for intoxication. Discussion : Short-term lithium treatment is associated with mild side effects. Medium and long-term lithium treatment, however, might have effects on target organs which may be prevented by periodical monitoring. Overall, lithium is still a safe option for the treatment of mood disorders.

title: Correlation and adaptation among functional and cognitive instruments for staging and monitoring Alzheimer?s disease in advanced stages

description: Background : Although Alzheimer’s disease (AD) is the most prevalent form of dementia, little is known about cognitive and functional aspects in its advanced stages. Objective : This study aimed the adaptation and correlation among specific instruments for AD in advanced stages with regard to cognition objectively weighted, besides the comparison between static and ecological aspects of functional capacity. Methods : 95 moderate, moderatly severe and severe AD patients (33 men and 62 women) underwent the scales CDR (Clinical for Dementia Rating), FAST (Functional Assessment Scale), MMSE (Mini-Mental State Exame), MMSEsev (Severe Mini-Mental State Examination), SIB-8 (Severe Impairment Battery) and TSI (Test for Severe Impairment), for the comparison with a golden-standard ecological scale the PADL (Performance Activities of Daily Living). Results : The evidence suggests an increasing and statistically significant linear correlation between the ecological functional scale and cognitive tests according to the stratification of AD stages once weighted by static functional scale. Discussion : The results indicate that for patients in advanced stages of AD, appropriate cognitive tests and performance-based functional scales are useful in more accurate assessment of disease staging and monitoring its progression.

title: Association study between COMT 158Met and creativity scores in bipolar disorder and healthy controls

description: Background Bipolar disorder (BD) patients have been reported to be associated higher creativity abilities, and recent data tend to support the hypothesis that dopaminergic system that could be associated with creativity. Catechol-O-methyltransferase (COMT) is one of the major enzymes involved in the metabolic degradation of dopamine. The COMT gene polymorphism (rs4680 or Val158Met) Met allele is reported to cause decreased activity of this enzyme in prefrontal cortex and improve performance in several cognitive domains. Objective The objective of this study was to evaluate the influence of Val158Met on creativity in BD type I and healthy controls. Methods Ninety-seven healthy volunteers and 120 BD type I were genotyped for COMT rs4680 and tested for creativity (Barrow Welsh Art Scale – BWAS) and intelligence Wechsler Abbreviated Scale of Intelligence (WASI). Results COMT Met allele positively influenced creativity scores in healthy controls but not in BD subjects during mood episodes and euthymia. The presence of allele Met did not influence IQ scores. No influence of IQ total score on creativity was observed. Limitations control group presented higher IQ scores and euthymic group was under medication use. Discussion Our research suggests positive effect of COMT rs4680 (allele Met) on creativity scores in healthy controls. One possible interpretation is that creativity is more likely to be associated with lesser degrees of bipolarity. The fact that the same results were not observed in BD may be associated to dysfunctions in the dopaminergic system that characterizes this disorder. Further studies with larger samples and other types of BD should explore the role of the dopaminergic system in creativity.

title: Peer support for people with mental illness

description: Background Peer support is a mutual aid system based on the belief that someone who faced/overcome adversity can provide support, encouragement and guidance to those who experience similar situations. Objective To conduct a systematic review that describes this concept and characterizes peer supporters, its practice and efficacy. Method Research on ISI Web of Science, EBSCO Psychology and Behavioral Sciences Collection and Medline databases (from 2001 to December 2013) was conducted using as keywords “mental illness”, “mental health”, “psychiatric disability”, “mental health services”, combined with “peer support”, “mutual support”, “self-help groups”, “consumers as providers”, “peer-run services”, “peer-run programs” and “social support”. Results We found 1,566 articles and the application of both the exclusion (studies with children, teenagers and elderly people; disease in comorbidity; peer support associated to physical illnesses or family members/caregivers) and the inclusion criteria (full text scientific papers, peer support or similar groups directed for schizophrenia, depression, bipolar or psychotic disorders) lead to 165 documents, where 22 were excluded due to repetition and 31 to incomplete text. We analyzed 112 documents, identifying as main peer support categories: characterization, peer supporter, practices and efficacy. Discussion Despite an increasing interest about this topic, there is no consensus, suggesting realizing more studies.

title: On the notion of causality in medicine: addressing Austin Bradford Hill and John L. Mackie

description: Almost 50 years ago appeared the seminal article by Austin Bradford Hill where he presented parameters for inferring causes from statistical associations, which became known as Hill’s causal criteria. This was a milestone for the renewal of the idea of cause in medicine. Our article revisits his contribution in light of the ideas from the Australian philosopher John L. Mackie, whose important works on causality reached an audience distinct from Hill’s. We suggest that both the British epidemiologist and the Australian philosopher share the purpose of articulating probabilistic determinism and multi-causality, the first with a predominantly probabilistic model and the second with an analytical approach. This article explores the possible consequences of addressing these authors jointly in regard to causal inferences in medicine, especially in respect to mental disorders.

title: Burden on relatives of people with psychic disorder: levels and associated factors

description: Background Studies have shown that overburden with care of psychotic patients is associated with a significant reduction of quality of life and causes harm to the caregiver’s health. Objective In order to compare factors associated with levels of burden of caregivers with the psychopathology of the patient, we conducted a cross-sectional study with 435 primary caregivers of patients of Centers for Psychosocial Care (CAPS) from Pelotas, RS. Methods The patients were identified through medical records and their caregivers were interviewed in their homes. To evaluate the burden we used Zarit Burden Interview (ZBI). Results Caregivers of dependent users of alcohol and drugs had the highest average of burden, 52.2 points (sd = 20.4), followed by the caregivers of patients with suicide risk, 48.5 points (sd = 0.7). In adjusted analysis, women had 8.2 (95% CI: 4.6, 11.8) points higher on average than men in ZBI scale. Caregivers with less education had 1.6 (95% CI: -3.1, -1.0) points lower on average of burden compared to those with higher educational level. Caregivers with some health problem had 6.7 (95% CI: 3.3, 10.0) points higher in the middle of the ZBI when compared to those without disease. Discussion Several factors overload clearly indicate the need to develop interventions such as psychoeducation which may give some support to the family responsible for care.

title: Relations between memory complaints, depressive symptoms and cognitive performance among community dwelling elderly

description: Background Memory complaints are quite common among the elderly; yet, the clinical relevance of these complaints to diagnose cognitive decline is debatable, since several different factors could be associated with them. Objective The present paper examined the correlations between memory complaints, depressive symptoms and cognitive performance in a group of 301 elderly individuals who lived in the district of Ermelino Matarazzo, São Paulo, and who participated in the population-based survey entitled Profiles of Frailty in Elderly Brazilians by the FIBRA Network. Methods Cognitive performance was assessed with the memorization test involving 10 common pictures, the Mini Mental State Examination (MMSE), the Verbal Fluency (VF) test, and the Clock Drawing Test, which comprise the Brief Cognitive Screening Battery (BCSB). Memory complaints were assessed with the Memory Complaint Questionnaire (MAC-Q), and depressive symptoms with the Geriatric Depression Scale (GDS). Results Female participants had higher rates of memory complaints when compared to male participants (p = 0.013). Subjects with less years of schooling had more severe memory complaints and poorer cognitive performance than those with more years of schooling (p &lt; 0.003). The presence of depressive symptoms was associated with poorer memory assessment scores (r = 0.39, p &lt; 0.001). Discussion Memory complaints were correlated with sex, schooling and depressive symptoms among elderly individuals residing in the community. No correlation was found between complaints and cognitive performance.

title: Internet and video game addictions: a cognitive behavioral approach

description: Background While several benefits are attributed to the Internet and video games, an important proportion of the population presents symptoms related to possible new technological addictions and there has been little discussion of treatment of problematic technology use. Although demand for knowledge is growing, only a small number of treatments have been described. Objective To conduct a systematic review of the literature, to establish Cognitive Behavioral Therapy (CBT) as a possible strategy for treating Internet and video game addictions. Method The review was conducted in the following databases: Science Direct on Line, PubMed, PsycINFO, Cochrane Clinical Trials Library, BVS and SciELO. The keywords used were: Cognitive Behavioral Therapy; therapy; treatment; with association to the terms Internet addiction and video game addiction. Given the scarcity of studies in the field, no restrictions to the minimum period of publication were made, so that articles found until October 2013 were accounted. Results Out of 72 articles found, 23 described CBT as a psychotherapy for Internet and video game addiction. The manuscripts showed the existence of case studies and protocols with satisfactory efficacy. Discussion Despite the novelty of technological dependencies, CBT seems to be applicable and allows an effective treatment for this population.
