Background As more patients are surviving intensive care, mental health concerns in survivors have become a research priority. Among these, post-traumatic stress disorder (PTSD) can have an important impact on the quality of life of critical care survivors. However, data on its burden are conflicting. Therefore, this systematic review and meta-analysis aimed to evaluate the prevalence of PTSD symptoms in adult critical care patients after intensive care unit (ICU) discharge. Methods We searched MEDLINE, EMBASE, LILACS, Web of Science, PsycNET, and Scopus databases from inception to September 2018. We included observational studies assessing the prevalence of PTSD symptoms in adult critical care survivors. Two reviewers independently screened studies and extracted data. Studies were meta-analyzed using a random-effects model to estimate PTSD symptom prevalence at different time points, also estimating confidence and prediction intervals. Subgroup and meta-regression analyses were performed to explore heterogeneity. Risk of bias was assessed using the Joanna Briggs Institute tool and the GRADE approach. Results Of 13,267 studies retrieved, 48 were included in this review. Overall prevalence of PTSD symptoms was 19.83% (95% confidence interval [CI], 16.72–23.13; I 2 = 90%, low quality of evidence). Prevalence varied widely across studies, with a wide range of expected prevalence (from 3.70 to 43.73% in 95% of settings). Point prevalence estimates were 15.93% (95% CI, 11.15–21.35; I 2 = 90%; 17 studies), 16.80% (95% CI, 13.74–20.09; I 2 = 66%; 13 studies), 18.96% (95% CI, 14.28–24.12; I 2 = 92%; 13 studies), and 20.21% (95% CI, 13.79–27.44; I 2 = 58%; 7 studies) at 3, 6, 12, and > 12 months after discharge, respectively. Conclusion PTSD symptoms may affect 1 in every 5 adult critical care survivors, with a high expected prevalence 12 months after discharge. ICU survivors should be screened for PTSD symptoms and cared for accordingly, given the potential negative impact of PTSD on quality of life. In addition, action should be taken to further explore the causal relationship between ICU stay and PTSD, as well as to propose early measures to prevent PTSD in this population.

Obesity has been pointed out as a risk factor for higher prevalence of asthma and asthma-related symptoms in adolescents. The objective was to evaluate the relationship between the prevalence of asthma and obesity in adolescents living in Santa Maria and surroundings (state of Rio Grande do Sul, southern Brazil), applying the International Study of Asthma and Allergies in Childhood (ISAAC) protocol. A total of 4,010 of 6,123 schoolchildren, 13 to 14 years of age, enrolled in the ISAAC phase III protocol (asthma core questionnaire) and were nutritionally evaluated: height, weight, and triceps skinfold (TSF) measurements. Prevalence of asthma (wheeze in the last 12 months) and prevalence of severe asthma (two or more affirmative responses to: more than 4 acute attacks of asthma, speech disturbance, sleep disturbance, wheezing with exercise) were evaluated and compared according to their nutritional status: obese and non-obese. Obese adolescents were defined by body mass index (BMI, in kg/m(2)) > or =85th percentile and TSF > or =85th percentile. Obese and non-obese groups were compared for prevalence of asthma and asthma severity using the Chi-square test and odds ratio (OR) with 95% confidence interval. Analyzing all adolescents, we observed a significant positive relationship between the prevalence of obesity and affirmative responses to "wheeze ever" (OR = 1.28; 95% CI 1.08-1.52), "wheezing with exercise" (OR = 1.36; 95% CI 1.11-1.66), "asthma ever" (OR = 1.29; 95% CI 1.03-1.62), and severe asthma (OR = 1.55; 95% CI 1.12-2.14). Among the boys, there was a significant positive association between obesity and "wheeze ever" (OR = 1.49; 95% CI 1.13-1.86). In girls, there was a significant positive relationship with "asthma ever" (OR = 1.38; 95% CI 1.01-1.88) and "wheezing with exercise" (OR = 1.36; 95% CI 1.11-1.66). This cross-sectional study with adolescents living in the southern region of Brazil showed that there is a positive association between obesity and prevalence of asthma symptoms and asthma severity, a finding mainly confined to girls.

The prevalence of asthma related symptoms were higher among those adolescents living in the urban centers in comparison to the rural ones. These differences were significant for wheezy ever, wheezy in the last 12 months, asthma ever, and wheezy with exercise in Caruaru and for wheezy ever and asthma ever, in Santa Maria. Comparing urban areas, the prevalence of asthma related symptoms in Caruaru was higher than in Santa Maria, except for wheezy ever and wheezy with exercise. The opposite was observed comparing rural areas: the prevalence of asthma (except for nocturnal cough) was higher in Santa Maria despite lesser severity of symptoms in this city.

A variety of new psychotherapy modalities has arisen in which the contact between patient and therapist takes place via the internet. The main objective of this systematic review is to investigate the types of online psychotherapy (OP) conducted nowadays, and to describe their main characteristics to psychodynamic psychotherapists who may wish to better understand the current scientific literature on the subject. The review used two databases, EMBASE and PsycINFO. Fifty-nine studies were retrieved and the main online psychotherapy modalities identified were self-therapy programmes using contact via email or chat; videoconference; and therapy exclusively via chat or email. The result of these studies suggests that OP is more effective than a waiting list control group. When compared with face-to-face therapies, OP showed similar effects. Most studies involved cognitive behavioural therapy; only two studies involved a form of psychodynamic psychotherapy. Different forms of communication allow patient and therapist to establish different relationships and therapeutic possibilities. OPs may be feasible treatment alternatives; however, it remains unclear, especially in relation to psychodynamic treatments, if therapeutic technique in OP, which involves changes in comparison with face-to-face therapies, would be useful in severe cases. Psychodynamic psychotherapists should adopt a posture of constant reflection on the changes taking place in the world and their impact on the minds of individuals, without, nevertheless, idealizing the 'new'. the therapist's location. Many people with mental health disorders fail to seek assistance or cannot afford to visit a doctor's office or mental healthcare centre, and the internet offers access to different therapeutic interventions.These studies throw light on the phenomenon, but online psychotherapies are considered new treatment modalities and are a rapidly expanding field. Most of the data presented in the aforementioned studies are contradictory and inconclusive. Systematic reviews on the subject assist the clinician and the researcher in knowing the state of the art on the subject and in positioning themselves more critically in terms of incorporating online treatment modalities in their practices. For psychodynamic psychotherapy in particular, it is necessary to critically discuss the effect of these technologies on the pillars of this theoretical approach, such as transference, countertransference and the analytic field. These concepts constitute the basis of psychodynamic practice and may be profoundly affected by a virtual relationship (Sfoggia et al., 2014). Therefore, we need to keep questioning the impact of online treatments in a psychodynamic psychotherapy setting.The main objective of this systematic review was to investigate the types of OP conducted nowadays, and to describe their main characteristics to psychodynamic psychotherapists who may wish to better understand the current scientific literature on the subject. The secondary objective was to describe the mai...

Objective: This study aims to describe the design, methods and sample characteristics of the Multidimensional Evaluation and Treatment of Anxiety in Children and Adolescents -the PROTAIA Project. Method: Students between 10 and 17 years old from all six schools belonging to the catchment area of the Primary Care Unit of Hospital de Clínicas de Porto Alegre were included in the project. It comprises five phases: (1) a community screening phase; (2) a psychiatric diagnostic phase; (3) a multidimensional assessment phase evaluating environmental, neuropsychological, nutritional, and biological factors; (4) a treatment phase, and (5) a translational phase. Results: A total of 2,457 subjects from the community were screened for anxiety disorders. From those who attended the diagnostic interview, we identified 138 individuals with at least one anxiety disorder (apart from specific phobia) and 102 individuals without any anxiety disorder. Among the anxiety cases, generalized anxiety disorder (n = 95; 68.8%), social anxiety disorder (n = 57; 41.3%) and separation anxiety disorder (n = 49; 35.5%) were the most frequent disorders. Conclusion:The PROTAIA Project is a promising research project that can contribute to the knowledge of the relationship between anxiety disorders and anxiety-related phenotypes with several genetic and environmental risk factors. Resumo Objetivo: o objetivo deste estudo é descrever o desenho, os métodos e as características amostrais da Avaliação Multidimensional e Tratamento da Ansiedade em Crianças e Adolescentes -Projeto PROTAIA. Método: Escolares entre 10 e 17 anos de todas as escolas pertencentes à área de abrangência da unidade de atenção primária do Hospital de Clínicas de Porto Alegre foram incluídos no projeto. O projeto compreende cinco fases: 1) triagem comunitária; 2) diagnóstico psiquiátrico; 3) avaliação multidimensional, incluindo fatores ambientais, neuropsicológicos, nutricionais e marcadores biológicos; 4) tratamento; e 5) fase translacional. Resultados: Um total de 2.457 sujeitos foram triados para transtornos de ansiedade na comunidade. Dos indivíduos que compareceram à avaliação diagnóstica, 138 foram detectados com ao menos um transtorno de ansiedade (excluindo fobia específica) e 102 indivíduos sem nenhum transtorno de ansiedade. Dentre os casos de ansiedade, o transtorno de ansiedade generalizada (n = 95; 68,8%), transtorno de ansiedade social (n = 57; 41,3%) e o transtorno de ansiedade de separação (n = 49; 35,5%) foram os mais frequentes. Conclusão: O projeto PROTAIA é um projeto de pesquisa promissor que pode contribuir para o entendimento da relação entre transtornos de ansiedade e fenótipos relacionados à ansiedade com vários fatores de risco, tanto genéticos quanto ambientais.

In this age of unprecedented expansion of media and information dissemination and sharing, the use of electronic means should be reconsidered. The use of new technologies should be studied to understand how it may affect the relationship between patient and therapist during psychotherapy or psychoanalytic treatments. This study offers a critical discussion of the effect of technologies on clinical practice, and vignettes are used to describe their impact on frame, anonymity, abstinence and therapeutic neutrality. Transfer and countertransference issues resulting from these changes are also discussed. The potential benefits of new technologies in psychotherapy are appreciated, but the authors draw attention to the need to reflect about the presence of the therapist in those technologies and the preservation of the therapeutic setting, so that a satisfactory progression of the work of the dyad is ensured. This study also discusses the use of technologies in the expansion of learning and application of the therapeutic technique to overcome geographic and time barriers, among others.

Different lines of evidence support BDNF as a candidate gene in mood and anxiety modulation. More recently, the Met allele of the BDNF Val66Met polymorphism has been implicated in anxiety in animal models and anxiety-traits in humans. The aim of this study is to evaluate the a priori hypothesis that the association between anxiety disorders and Val66Met polymorphism at the BDNF gene would be replicated in a community sample of children and adolescents. 240 subjects from a total sample of 2457 children and adolescents aged 10-17 years from the public schools in the catchment area of the primary care unit of a university hospital participated in this case-control study and were assessed for psychopathology using the K-SADS-PL. A sample of saliva was collected for DNA analysis of Val66Met polymorphism. BDNF was the single gene evaluated in this sample. We found a significant association between carrying one copy of the Met allele and higher chance of anxiety disorders in children and adolescents. The association remained positive even after the adjustment for potential confounders (228 subjects; OR=3.53 (CI95% 1.77-7.06; p<0.001)). Our results support the a priori hypothesis of an association between anxiety and the polymorphism Val66Met. To our knowledge, this is the first study documenting a potential role of this polymorphism in a community sample of anxious children and adolescents.
