RESUMEN
BACKGROUND: Anxiety is a common and disabling condition that significantly impacts quality of life. Subsyndromal anxiety (SSA) refers to anxiety symptoms that do not meet the full diagnostic criteria for an anxiety disorder but pose a risk for developing such disorders. We aimed to provide practical recommendations for the treatment of SSA in primary care settings. METHODS: A narrative review was conducted to identify strategies for recognizing and treating patients with SSA. RESULTS: The recommendations for treating SSA include lifestyle modifications such as exercise and stress reduction techniques, psychotherapy, and pharmacological treatments, including natural compounds like the lavender oil extract Silexan. Regular follow-up care is essential to monitor treatment response and address ongoing symptoms. Additionally, the use of the GAD-7 tool is recommended for accurately identifying patients with SSA. CONCLUSION: Implementing these recommendations in primary care can lead to effective treatment of SSA, preventing the development of more severe anxiety disorders. An integrative approach, combining lifestyle modifications, psychotherapy, and pharmacotherapy, including natural compounds, offers significant benefits for managing anxiety.

RESUMEN
Anxiety disorders are very prevalent and often persistent mental disorders, with a considerable rate of treatment resistance which requires regulatory clinical trials of innovative therapeutic interventions. However, an explicit definition of treatment-resistant anxiety disorders (TR-AD) informing such trials is currently lacking. We used a Delphi method-based consensus approach to provide internationally agreed, consistent and clinically useful operational criteria for TR-AD in adults. Following a summary of the current state of knowledge based on international guidelines and an available systematic review, a survey of free-text responses to a 29-item questionnaire on relevant aspects of TR-AD, and an online consensus meeting, a panel of 36 multidisciplinary international experts and stakeholders voted anonymously on written statements in three survey rounds. Consensus was defined as ≥75% of the panel agreeing with a statement. The panel agreed on a set of 14 recommendations for the definition of TR-AD, providing detailed operational criteria for resistance to pharmacological and/or psychotherapeutic treatment, as well as a potential staging model. The panel also evaluated further aspects regarding epidemiological subgroups, comorbidities and biographical factors, the terminology of TR-AD vs. "difficult-to-treat" anxiety disorders, preferences and attitudes of persons with these disorders, and future research directions. This Delphi method-based consensus on operational criteria for TR-AD is expected to serve as a systematic, consistent and practical clinical guideline to aid in designing future mechanistic studies and facilitate clinical trials for regulatory purposes. This effort could ultimately lead to the development of more effective evidence-based stepped-care treatment algorithms for patients with anxiety disorders.
RESUMEN
Manual sleep staging (MSS) using polysomnography is a time-consuming task, requires significant training, and can lead to significant variability among scorers. STAGER is a software program based on machine learning algorithms that has been developed by Medibio Limited (Savage, MN, USA) to perform automatic sleep staging using only EEG signals from polysomnography. This study aimed to extensively investigate its agreement with MSS performed during clinical practice and by three additional expert sleep technicians. Forty consecutive polysomnographic recordings of patients referred to three US sleep clinics for sleep evaluation were retrospectively collected and analyzed. Three experienced technicians independently staged the recording using the electroencephalography, electromyography, and electrooculography signals according to the American Academy of Sleep Medicine guidelines. The staging initially performed during clinical practice was also considered. Several agreement statistics between the automatic sleep staging (ASS) and MSS, among the different MSSs, and their differences were calculated. Bootstrap resampling was used to calculate 95% confidence intervals and the statistical significance of the differences. STAGER's ASS was most comparable with, or statistically significantly better than the MSS, except for a partial reduction in the positive percent agreement in the wake stage. These promising results indicate that STAGER software can perform ASS of inpatient polysomnographic recordings accurately in comparison with MSS.
RESUMEN
Objective: Selective serotonin reuptake inhibitors (SSRIs) are the cornerstone of treatment of major depressive disorder (MDD). However, non-response is common, often necessitating combination strategies. The present study assessed the efficacy of vortioxetine as an add-on therapy in patients with SSRI-resistant MDD. Methods: The charts of 36 adult outpatients with DSM-IV-TR MDD who had not achieved a response after at least 8 weeks of treatment with an SSRI were reviewed retrospectively. Subjects were treated with vortioxetine (5-20 mg/day) for 8 weeks added to the current SSRI. The main outcome measures were change from baseline in total Hamilton Scale for Depression (HAM-D) score and the rate of response (a 50% or greater reduction in HAM-D score and a Clinical Global Impression ‐ Improvement module [CGI-I] score of 1 or 2 at endpoint). HAM-D scores ≤ 7 were considered as remission. Additional outcome measures included the Snaith-Hamilton Pleasure Scale (SHAPS) and the Scale for Suicide Ideation (SSI). Results: 32 patients completed the 8 weeks of treatment. At 8 weeks, a significant reduction in HAM-D score was observed (p ≤ 0.001), with response obtained by 41.7% and remission by 33.3% of patients. Significant reductions in SHAPS and SSI were also observed (p ≤ 0.001 for both scales). Conclusions: Adjunctive vortioxetine may be useful and well-tolerated in stage I treatment-resistant depression. However, the limitations of this study (such as small sample size, absence of randomization and control group, retrospective design, etc.) must be considered.

Objective: As obsessive-compulsive disorder (OCD) is a relatively common psychiatric disorder with a significant suicide risk, the individuation of potential biomarkers of suicidality, such as cholesterol levels, may enable recognition of at-risk subjects. Therefore, the aims of this study were to: 1) evaluate potential differences in clinical and laboratory parameters between patients with and without alexithymia and compare them with healthy controls; and 2) investigate which clinical and laboratory variables were associated with suicidal ideation. Methods: 79 drug-naïve adult outpatients with a DSM-IV diagnosis of OCD were recruited. Alexithymia was measured with the 20-item Toronto Alexithymia Scale (TAS-20), suicidal ideation was assessed with the Scale for Suicide Ideation, and depressive symptoms were evaluated with the Montgomery-Åsberg Depression Rating Scale (MADRS). Serum lipid levels of 40 healthy controls were also evaluated. Results: Alexithymic patients had altered serum lipid levels in comparison with non-alexithymics and healthy controls. Using a linear regression model, the presence of symmetry/ordering obsessions and compulsions, lower HDL-C levels, and difficulty in identifying feelings dimension of the TAS-20 were associated with higher suicidal ideation. Conclusions: Alexithymic individuals with OCD may exhibit dysregulation of the cholesterol balance, which in turn may be linked to suicidal ideation. Further prospective studies are required to elucidate this potential association. .

OBJECTIVE: To investigate the possible influence of psychological variables on cardiorespiratory responses and perceived exertion of patients with Panic Disorder (PD) during a submaximal exercise test. METHOD: Ten outpatients with PD and 10 matched healthy subjects walked up on a treadmill slope at a speed of 4 km/h in order to reach 65 percent of their maximum heart rate. Cardiorespiratory variables were continuously recorded. Before the exercise, the state and trait anxiety (State-Trait Anxiety Inventory scores), fear of physical sensations (Body Sensation Questionnaire scores), and fear of autonomic arousal (Anxiety Sensitivity Index scores) were assessed; during the exercise, levels of anxiety (VAS-A) and exertion (Borg Scale CR 10) were measured. RESULTS: Compared to controls, patients reached earlier the target HR and the ventilatory threshold, showed lower oxygen consumption, higher HR and lower within-subject standard deviations of HR (a measure of cardiac variability). Exertion was also higher, and there was a significant correlation between breathing frequency, tidal volume and HR. No significant associations were found between cardiorespiratory response, perceived exertion, and psychological variables in patients with PD. CONCLUSION: Although patients with PD presented poor cardiorespiratory fitness and were required to spend more effort during physical exercise, this did not appear to be related to the psychological variables considered. Further studies with larger groups are warranted.
OBJETIVO: Investigar a possível influência de variáveis psicológicas na resposta cardiorrespiratória e percepção de esforço dos pacientes com Transtorno do Pânico (TP) durante exercício físico de intensidade submáxima. MÉTODO: Dez pacientes ambulatoriais com TP e dez controles saudáveis foram submetidos a uma caminhada na velocidade de 4 km/h em uma rampa inclinada. A inclinação da rampa foi aumentada até que fosse atingida 65 por cento da frequência cardíaca máxima (FC alvo). Variáveis cardiorespiratorias foram monitoradas continuamente. Antes do exercício o Inventário de Estado-Traço de Ansiedade, o Índice de Sensibilidade à Ansiedade e o Questionário de Sensações Corporais foram aplicados. Durante o exercício, o nível de ansiedade (Escala Análoga Visual para Ansiedade - VAS-A) e esforço (Escala Borg CR 10) foram medidos. RESULTADOS: Comparados aos controles, os pacientes atingiram a FC alvo e o limiar respiratório mais rápido, tiveram menor consumo de oxigênio, FC mais alta e menor desvio padrão da FC em cada sujeito (medida de variabilidade cardíaca). O esforço também foi maior e houve uma correlação significativa entre frequência respiratória, volume corrente e FC. Nenhuma associação significativa foi encontrada entre cardiorrespiratória resposta, percepção de esforço e variáveis psicológicas em pacientes com TP. CONCLUSÃO: Pacientes com TP mostrou baixa aptidão cardiorrespiratória e maior esforço durante o exercício físico que não pareceu estar relacionada com as variáveis psicológicas consideradas. Mais estudos em grupos maiores são necessários.

CONTEXTO: Atualmente há na literatura um crescente interesse na interface entre exercício físico e transtornos psiquiátricos. Apesar disso, ainda há uma deficiência de instrumentos de autorrelato para medir os níveis de atividade física dos pacientes. OBJETIVO: A tradução, a aferição da equivalência semântica e uma aplicação piloto (n = 30), sem pretensão psicométrica, do Questionário de Atividade Física Habitual, visando sua utilização na população brasileira de diferentes níveis de escolaridade. MÉTODOS: O processo envolveu duas traduções e retrotraduções realizadas por avaliadores independentes, avaliação das versões seguida da elaboração de uma versão síntese e pré-teste comentado. RESULTADOS: A maioria dos participantes (91 por cento) não apresentou dificuldades de compreensão com o questionário. Para cada item do instrumento, apresentam-se os resultados das quatro etapas. Mais estudos são necessários para determinar a adequação para populações de baixa escolaridade. Os autores recomendam que sujeitos menos instruídos sejam supervisionados ao preencher o questionário. CONCLUSÕES: A utilização de duas versões de tradução e retrotradução, a discussão sobre a versão síntese e a interlocução com a população-alvo proporcionam maior segurança ao processo de equivalência semântica.
BACKGROUND: There has been a growing scientific interest on the interface between exercise and psychiatric disorders. However, there is a lack of self-report instruments to assess levels of physical activity adapted to Brazilian Portuguese. OBJECTIVE: To translate, assess the semantic equivalence of the Habitual Physical Activity Questionnaire and perform a non-psychometric pre-test with subjects (n = 30) from the Brazilian population, with different educational backgrounds. METHODS: The cross-cultural adaptation process consisted of two translations and back translations performed by two independent evaluators; an evaluation of the versions and the development of a synthetic version; and a commented pretest of the questionnaire. RESULTS: For each item of the instrument, the results of the four stages are reported. Most of the participants (91 percent) did not present any difficulties comprehending the items of the instrument. Further studies should be addressed to determine the adequacy of using this instrument in the less-educated population. We recommend that less instructed subjects be supervised while responding the questionnaire. DISCUSSION: The use of two translations versions, their critical appraisal and the assessment of the target population conceives more safety to the process of semantic equivalence.
