Crise global da atenção primária à saúde / Global crisis in primary health care / Crisis global de la atención primaria

Enquanto no Norte Global se discute uma crise na Atenção Primária à Saúde, a maioria dos países nunca chegou a constituir sistemas de saúde baseados propriamente numa atenção primária robusta. Nesse cenário, o Brasil apresenta uma tendência mais favorável, com conquistas importantes para a atenção primária e a medicina de família e comunidade nos últimos dez anos. Restam desafios a serem superados para que o Sistema Único de Saúde alcance níveis satisfatórios de acesso a seus serviços, com profissionais adequadamente formados e valorizados pela população.

While the Global North is discussing a crisis in primary health care, the majority of countries have never managed to establish health systems based on robust primary care. Brazil presents a more favorable trend, with important achievements for primary care and family practice over the last ten years. There are still challenges to be overcome so that the Unified Health System achieves satisfactory levels of access to its services, with professionals who are properly trained and valued by the public.

Mientras que en el Norte Global se habla de una crisis de la atención primaria, la mayoría de los países nunca han creado realmente sistemas sanitarios basados en una atención primaria robusta. Brasil, muestra una tendencia más favorable, con importantes logros para la atención primaria y la medicina familiar y comunitaria en los últimos diez años. Aún quedan retos por superar para que el Sistema Único de Salud alcance niveles satisfactorios de acceso a sus servicios, con profesionales debidamente formados y valorados por la población.

Examining the unique relationships between problematic use of the internet and impulsive and compulsive tendencies: network approach.

BACKGROUND: Both impulsivity and compulsivity have been identified as risk factors for problematic use of the internet (PUI). Yet little is known about the relationship between impulsivity, compulsivity and individual PUI symptoms, limiting a more precise understanding of mechanisms underlying PUI. AIMS: The current study is the first to use network analysis to (a) examine the unique association among impulsivity, compulsivity and PUI symptoms, and (b) identify the most influential drivers in relation to the PUI symptom community. METHOD: We estimated a Gaussian graphical model consisting of five facets of impulsivity, compulsivity and individual PUI symptoms among 370 Australian adults (51.1% female, mean age = 29.8, s.d. = 11.1). Network structure and bridge expected influence were examined to elucidate differential associations among impulsivity, compulsivity and PUI symptoms, as well as identify influential nodes bridging impulsivity, compulsivity and PUI symptoms. RESULTS: Results revealed that four facets of impulsivity (i.e. negative urgency, positive urgency, lack of premeditation and lack of perseverance) and compulsivity were related to different PUI symptoms. Further, compulsivity and negative urgency were the most influential nodes in relation to the PUI symptom community due to their highest bridge expected influence. CONCLUSIONS: The current findings delineate distinct relationships across impulsivity, compulsivity and PUI, which offer insights into potential mechanistic pathways and targets for future interventions in this space. To realise this potential, future studies are needed to replicate the identified network structure in different populations and determine the directionality of the relationships among impulsivity, compulsivity and PUI symptoms.

Problematic pornography use and novel patterns of escalating use: A cross-sectional network analysis with two independent samples.

Modern internet pornography allows users to harness sexual novelty in numerous ways, which can be used to overcome desensitisation through increasing volume of use (quantitative tolerance), progressing to more stimulating genres (qualitative escalation), skipping between stimuli (tab-jumping), delaying orgasm ('edging'), and engaging in pornographic binges. However, existing research has not yet evaluated how these potentially reciprocal consumption patterns relate to problematic pornography use (PPU). To this end, we recruited two independent samples of male pornography users (N1 = 1,356, Mage = 36.86, SD = 11.26; N2 = 944, Mage = 38.69, SD = 12.26) and examined the relationships between these behavioural dimensions and self-reported difficulties in controlling one's pornography use. Data were analysed through the network analysis approach (using Gaussian graphical models). As hypothesised, i) quantitative tolerance was centrally placed within the overall network, and ii) acted as a statistical bridge node between other patterns of pornography use (e.g., pornographic binges), and all measured facets of PPU. Our results are consistent with other emerging literature suggesting that tolerance, pornographic binges, tab-jumping, and edging behaviours as relevant features ofPPU, and that upscaling overall usage may connect broader patterns of use with problematic engagement. Clinical and theoretical implications, as well as future research directions, are discussed.

Co-occurring PTSD in intensive OCD treatment: Impact on treatment trajectory vs. response.

BACKGROUND: Obsessive-compulsive disorder (OCD) and co-occurring posttraumatic stress disorder (PTSD) is associated with more severe and chronic OCD. However, findings regarding treatment effectiveness of cognitive behavioral treatment (CBT) with exposure and response prevention (ERP) with this comorbidity are mixed. Research aimed at understanding the precise barriers to OCD treatment effectiveness for individuals with co-occurring PTSD may help elucidate unique treatment needs. METHODS: The current study used linear regression and latent growth curve analysis comparing treatment response and trajectory from patients with OCD (n = 3083, 94.2 %) and OCD + PTSD (n = 191, 5.2 %) who received CBT with ERP in two major intensive OCD treatment programs. RESULTS: Although patients with OCD + PTSD evidenced similar trajectories of overall severity change, patients at one site required nearly 11 additional treatment days to achieve comparable reduction in OCD severity. Further, at the dimensional level, those with OCD + PTSD had poorer treatment response for unacceptable thoughts and symmetry symptoms. The moderate effect for unacceptable thoughts, indicating the widest gap in treatment response, suggests these symptoms may be particularly relevant to PTSD. LIMITATIONS: Findings are limited by a naturalistic treatment sample with variation in treatment provision. CONCLUSIONS: Findings emphasize caution in using a one-size-fits-all approach for patients with co-occurring OCD + PTSD within intensive OCD treatment programs, as broadly defined outcomes (e.g., reduction in overall severity) may not translate to reduction in the nuanced symptom dimensions likely to intersect with trauma. Unacceptable thoughts and symmetry symptoms, when co-occurring with PTSD, may require a trauma-focused treatment approach within intensive OCD treatment.

Assessing Adherence to Vaccination, Social Distancing and Other Preventive Behaviors by Patients With Mental Disorders in the Context Of Covid-19 Pandemic: A Scoping Review Protocol.

The COVID-19 pandemic has emerged as a worldwide public health crisis, leading to significant disruptions in societal behaviors and norms. Within the affected population, individuals with mental health disorders are considered a vulnerable group, experiencing higher infection rates and poorer outcomes. These adverse outcomes can be attributed to various factors, including inadequate adherence to vaccination and other preventive measures. To address this issue, this study aims to present the research protocol for a scoping review that will comprehensively examine the literature on the adherence of individuals with mental disorders to preventive behaviors during the COVID-19 pandemic. The scoping review will adhere to the methodological guidelines outlined by the Joanna Briggs Institute and will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. A comprehensive search for published literature containing original data will be conducted in the Embase, MEDLINE, PsycINFO, and Web of Science databases. The search strategy will be developed based on the Population, Concept, and Context inclusion criteria. Two authors will independently screen titles, abstracts, and full texts for inclusion and extract relevant data. The findings of the review will be presented using descriptive statistics, including tables, charts, and flow diagrams, to elucidate the key concepts of interest.

Clarifying and extending our understanding of problematic pornography use through descriptions of the lived experience.

Problematic pornography use (PPU) is a complex and growing area of research. However, knowledge of the PPU lived experience is limited. To address this gap, we conducted an online qualitative study with 67 individuals who self-identified as having problematic pornography use (76% male; Mage = 24.70 years, SD = 8.54). Results indicated several dimensions that have not been fully explored in the literature. These included various mental and physical complaints following periods of heavy pornography use, sexual functioning deficits with real partners, and a subjectively altered state of sexual arousal while using pornography. Moreover, we expanded on current knowledge regarding the inner conflict associated with PPU and clarified the ways that users can progress to increasingly intensified patterns of pornography use, such as tolerance/escalation and pornographic binges. Our study highlights the complex and nuanced nature of PPU and provides suggestions for future research and clinical practice.

Habit-, reward- and fear-related motivations in alcohol use disorder: A one-year prospective study.

OBJECTIVE: Cross-sectional studies show that habitual use of alcohol is associated with severity of alcohol dependence reflected across a range of domains and lower number of detoxifications in multiple settings. In this study, we investigated whether alcohol use disorder (AUD) patients with greater habitual use of alcohol at baseline showed worse outcomes after one year of follow-up. METHODS: A sample of inpatients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) alcohol use disorder (AUD) was assessed at baseline (n = 50) and after one year (n = 30). The Habit, Reward, and Fear Scale (HRFS) was employed to quantify affective (fear or reward) and non-affective (habitual) drives for alcohol use, the Alcohol Dependence Scale (ADS) was used to assess clinical outcomes, and the Depression, Anxiety and Stress Scale (DASS-21) was used to quantify and control for associated affective symptoms. RESULTS: There was a significant reduction in the three HRFS scores at the follow-up. Regression analyses demonstrated that greater habit- and fear-related drives at baseline predicted greater decreases in the ADS scores at the endpoint. However, after controlling for age, sex and affective symptoms, only reward and fear were associated with reductions in ADS scores at the end of one year. Prescriptions of naltrexone and antidepressants/benzodiazepines did not predict decreases in reward and fear-related motivations. CONCLUSION: Although we were unable to confirm that habitual subscores at baseline predict worse long-term outcomes among inpatients with AUD, we found that a greater fear and reward motives for the use of alcohol predicted a greater magnitude of improvement in the AUD symptoms after one year. We hope that these findings will help develop new approaches toward AUD treatment and inform models of addiction research.

Considerations for the treatment of obsessive-compulsive disorder in patients who have comorbid major depression.

INTRODUCTION: Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder that affects a significant number of individuals worldwide. Major depressive disorder (MDD) is among the most common comorbidities reported in people with OCD. The emergence of MDD in individuals with OCD can be attributed to the increased severity of OCD symptoms and their profound impact on daily functioning. Depressive symptoms can also modify the course of OCD. AREAS COVERED: In this review, the authors explore potential shared neurobiological mechanisms that may underlie both OCD and MDD, such as disturbed sleep patterns, immunological dysregulations, and neuroendocrine changes. Furthermore, they address the challenges clinicians face when managing comorbid OCD and MDD. The authors also discuss a range of treatment options for OCD associated with MDD, including augmentation strategies for serotonin reuptake inhibitors (e.g. aripiprazole), psychotherapy (especially CBT/EPR), transcranial magnetic stimulation (TMS), electroconvulsive therapy (ECT), and deep brain stimulation (DBS). EXPERT OPINION: Although there is no 'rule of thumb' or universally acceptable strategy in the treatment of OCD comorbid with MDD, many clinicians, including the authors, tend to adopt a unique transdiagnostic approach to the treatment of OCD and related disorders, focusing on strategies known to be effective across diagnoses. Nevertheless, the existing 'cisdiagnostic approaches' still retain importance, i.e. specific therapeutic strategies tailored for more severe forms of individual disorders.

Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders guidelines for the treatment of adult obsessive-compulsive disorder. Part II: cognitive-behavioral therapy

Objectives: To summarize evidence-based cognitive-behavioral therapy (CBT) treatment and propose clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The literature on CBT interventions for adult OCD, including BT and exposure and response prevention, was systematically reviewed to develop updated clinical guidelines for clinicians, providing comprehensive details about the necessary procedures for the CBT protocol. We searched the literature from 2013-2020 in five databases (PubMed, Cochrane, Embase, PsycINFO, and Lilacs) regarding study design, primary outcome measures, publication type, and language. Selected articles were assessed for quality with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association. Results: We examined 44 new studies used to update the 2013 American Psychiatric Association guidelines. High-quality evidence supports CBT with exposure and response prevention techniques as a first-line treatment for OCD. Protocols for Internet-delivered CBT have also proven efficacious for adults with OCD. Conclusion: High-quality scientific evidence supports the use of CBT with exposure and response prevention to treat adults with OCD.

OBJECTIVE: To summarize the evidence-based cognitive-behavioral therapy (CBT) treatment and propose clinical interventions for adult patients with obsessive-compulsive disorder (OCD). METHODS: A systematic review of the literature on CBT interventions for the treatment of adult OCD, comprising behavior therapy and exposure and response prevention (ERP) was done. The objective of this study is to present updated clinical guidelines to clinicians, providing comprehensive details regarding the necessary procedures to be incorporated into the CBT protocol. We searched the literature published from 2013-2020 in five databases (PubMed, Cochrane, Embase, Psycinfo and Lilacs), considering: study design, primary outcome measures, type of publication and language. Selected articles were assessed for quality with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association (ACC/AHA). RESULTS: We examined 44 new studies used to update the APA guidelines from 2013. High-quality evidence supports CBT including ERP techniques as the first-line CBT treatment for OCD. In addition, protocols for internet-delivered CBT have also demonstrated their efficacy for the treatment of adults with OCD. CONCLUSION: CBT based on ERP is a widely used treatment according to high-quality scientific evidence to treat adults with OCD.

A "transatlantic" follow-up study of the impact of the COVID-19 pandemic on patients with obsessive-compulsive disorder.

BACKGROUND: Obsessive-compulsive symptom fluctuations may be contingent on the number of stressful pandemic-related events and the resilience characterizing different cultures. We investigated the influence of the pandemic on symptom changes in a sample of obsessive-compulsive disorder (OCD) patients from Brazil and Italy, two countries that were highly affected by the outbreak. METHODS: Ninety-one OCD outpatients were evaluated at baseline and about one year later. Thirty of them were assessed in Brazil and 61 in Italy. Socio-demographic variables, symptoms' severity and the number of stressful pandemic-related events were collected. Comparisons between countries' samples were performed, and a linear regression examined whether the country of origin, demographic features and the number of stressful events were able to predict the symptoms' severity at the follow-up. RESULTS: Brazilian patients experienced more stressful pandemic-related events than Italian patients (p = 0.018). However, along with higher age (p < 0.01) and increased severity of symptoms at baseline (p < 0.01), lower number of events predicted increased symptoms' severity after one year (p < 0.01). Country of origin was not a significant predictor of severity. LIMITATIONS: Small number of subjects; lack of information regarding duration of illness; and potential sample differences between countries. CONCLUSIONS: During the pandemic, the occurrence of more stressful pandemic-related events was associated with decreased severity of patients' OCD symptoms. Nevertheless, older patients and those with more severe symptoms seemed prone to exhibit increased OCD severity at follow-up.

A Novel, Expert-Endorsed, Neurocognitive Digital Assessment Tool for Addictive Disorders: Development and Validation Study.

BACKGROUND: Many people with harmful addictive behaviors may not meet formal diagnostic thresholds for a disorder. A dimensional approach, by contrast, including clinical and community samples, is potentially key to early detection, prevention, and intervention. Importantly, while neurocognitive dysfunction underpins addictive behaviors, established assessment tools for neurocognitive assessment are lengthy and unengaging, difficult to administer at scale, and not suited to clinical or community needs. The BrainPark Assessment of Cognition (BrainPAC) Project sought to develop and validate an engaging and user-friendly digital assessment tool purpose-built to comprehensively assess the main consensus-driven constructs underpinning addictive behaviors. OBJECTIVE: The purpose of this study was to psychometrically validate a gamified battery of consensus-based neurocognitive tasks against standard laboratory paradigms, ascertain test-retest reliability, and determine their sensitivity to addictive behaviors (eg, alcohol use) and other risk factors (eg, trait impulsivity). METHODS: Gold standard laboratory paradigms were selected to measure key neurocognitive constructs (Balloon Analogue Risk Task [BART], Stop Signal Task [SST], Delay Discounting Task [DDT], Value-Modulated Attentional Capture [VMAC] Task, and Sequential Decision-Making Task [SDT]), as endorsed by an international panel of addiction experts; namely, response selection and inhibition, reward valuation, action selection, reward learning, expectancy and reward prediction error, habit, and compulsivity. Working with game developers, BrainPAC tasks were developed and validated in 3 successive cohorts (total N=600) and a separate test-retest cohort (N=50) via Mechanical Turk using a cross-sectional design. RESULTS: BrainPAC tasks were significantly correlated with the original laboratory paradigms on most metrics (r=0.18-0.63, P<.05). With the exception of the DDT k function and VMAC total points, all other task metrics across the 5 tasks did not differ between the gamified and nongamified versions (P>.05). Out of 5 tasks, 4 demonstrated adequate to excellent test-retest reliability (intraclass correlation coefficient 0.72-0.91, P<.001; except SDT). Gamified metrics were significantly associated with addictive behaviors on behavioral inventories, though largely independent of trait-based scales known to predict addiction risk. CONCLUSIONS: A purpose-built battery of digitally gamified tasks is sufficiently valid for the scalable assessment of key neurocognitive processes underpinning addictive behaviors. This validation provides evidence that a novel approach, purported to enhance task engagement, in the assessment of addiction-related neurocognition is feasible and empirically defensible. These findings have significant implications for risk detection and the successful deployment of next-generation assessment tools for substance use or misuse and other mental disorders characterized by neurocognitive anomalies related to motivation and self-regulation. Future development and validation of the BrainPAC tool should consider further enhancing convergence with established measures as well as collecting population-representative data to use clinically as normative comparisons.

Prevalence and psychopathology features of mental rituals in patients with obsessive-compulsive disorder: A descriptive exploratory study of 1001 patients.

INTRODUCTION: Mental rituals (MR) are compulsions with no overt behavioural or motoric signs. It is presently unclear whether MR found in obsessive-compulsive disorder are associated with a distinctive clinical profile. OBJECTIVES: The main objectives of this paper were to assess the prevalence and psychopathological correlates of mental rituals in a large sample of OCD patients. METHODS: This exploratory case-control study compared 519 patients with versus 447 without MR in terms of sociodemographics, presence and severity of obsessive-compulsive symptoms, psychiatric comorbidities, sensory phenomena, suicidality, and insight. RESULTS: Current MR were found in 51.8%, while lifetime MR were found in 55.4% of the sample. The multiple logistic regression model determined that the most relevant clinical factors independently associated with current MR in OCD patients were the absence of any sensory phenomena and the presence of lifetime suicide ideation. CONCLUSION: Due to its relation to OCD clinical aspects, MR are a frequent feature among OCD patients. It also seems to be associated with a range of features that are probably relevant for treatment, especially sensory phenomena and suicidality.

Concealing, Tolerating, and Adjusting to Emotions in Obsessive-Compulsive and Anxiety Disorders: A Cross-Sectional Study.

BACKGROUND: Although research has shown that mood and anxiety disorders manifest disturbed emotion regulation, it is unclear whether anxiety disorders differ between each other in terms of their emotion regulation strategies. In the present study, we investigated whether patients with anxiety disorders present different affective styles. METHODS: We assessed affective styles of 32 obsessive-compulsive disorder (OCD) patients, 29 social anxiety disorder (SAD) patients, 29 panic disorder (PD) patients, and 20 healthy controls through the Affective Style Questionnaire (ASQ). A multivariate analysis of covariance (MANCOVA) was performed to compare the affective styles across groups (OCD, SAD, PD and control), while controlling for depression, anxiety symptoms and age. RESULTS: The MANCOVA revealed a significant, small-medium, main effect of diagnostic group on affective styles. The planned contrasts revealed that OCD and SAD patients reported significantly lower scores for "tolerance" (ASQ-T) compared to healthy controls group. There were no differences between PD group and healthy controls. CONCLUSIONS: Our findings provide evidence that OCD and SAD have difficulty tolerating strong emotions existing in the present moment in an open and non-defensive way.

Non­urgent use of the emergency department: a qualitative semi­structured interview study, Vitória-ES, 2019. / Uso de serviço de emergência por motivos não urgentes: estudo qualitativo com usuários de um pronto-atendimento, Vitória-ES, 2019.

Introduction: The healthcare system is structured to prioritize Primary Health Care (PHC) as the main gateway for accessing care while reserving emergency services for situations requiring immediate attention. However, people's choices often deviate from what one would expect based on their health needs, leading to overburdened emergency services and reduced clinical care effectiveness and efficiency. Objective: This study aims to identify the motivations behind non-urgent health issues leading users to seek care at an emergency department. Method: A qualitative study involving semi-structured interviews was conducted in 2019 with users of an emergency department in Vitória-ES. The collected data underwent thematic analysis. Results: The study included 29 participants, predominantly women, of Black or mixed race, and under 30 years old, who reported issues related to pain or respiratory problems. Notably, participants perceived emergency services as places where they could readily obtain immediate and effective care. Accessing PHC was seen as challenging, and they anticipated that their needs (appointments, tests, medications) would not be promptly met within PHC. Conclusion: Utilizing emergency services for non-urgent concerns is a multifaceted and complex public health problem that extends beyond PHC access difficulties to encompass individual and collective understanding of PHC's role and emergency care. Merely expanding PHC is insufficient; reframing this level care is essential, particularly among younger individuals.

Introdução: o sistema de saúde é organizado de uma forma que prevê a Atenção Primária à Saúde (APS) como a porta de entrada preferencial para o cuidado, destinando-se os serviços de emergência para situações que exigem atendimento imediato. Contudo, o caminho percorrido pelas pessoas nem sempre reflete o que se esperaria pelo perfil de sua necessidade de saúde, resultando em sobrecarga e baixa efetividade e eficiência dos serviços de emergência. Objetivo: identificar motivações para uso pronto-atendimentos por problemas de saúde não urgentes em usuários deste serviço. Método: estudo qualitativo baseado em entrevistas semiestruturadas realizadas em 2019 com usuários de um pronto-atendimento do município de Vitória-ES. Os dados foram submetidos à análise temática derivada da análise de conteúdo. Resultados: Participaram 29 pessoas, sendo a maioria mulheres, negras ou pardas, com menos de 30 anos, queixando-se de dor ou problema respiratório. Observou-se, dentre outras coisas, que os entrevistados percebem os serviços urgência e emergência como aqueles onde obterão cuidados imediatos com maior facilidade e resolubilidade, já que é difícil acessar a APS e nela muito provavelmente não terão tudo aquilo que consideram necessário para manejar seu problema (consulta, exames e medicações) de uma maneira imediata, rápida e resolutiva. Conclusão: A utilização de pronto-atendimentos por motivos não urgentes é uma questão complexa. Envolve não apenas a dificuldade de acesso à APS, mas a própria compreensão individual e coletiva do papel da APS e do pronto-atendimento. Não basta, portanto, expandir a APS, mas é preciso também ressignificá-la, em especial junto aos mais jovens.

Animal hoarding: a systematic review

Objectives: Animal hoarding is a special manifestation of hoarding disorder, characterized by the accumulation of animals and failure to provide them with minimal care. The main objective of this systematic review is to evaluate the characteristics of animal hoarding, focusing on the profile of affected individuals and the features of accumulation behavior. Methods: A systematic search of the literature was conducted in the electronic databases MEDLINE, Scopus, and LILACS until October 2022. We included case series (n ≥ 10) and cross-sectional studies assessing animal hoarding. Results: A total of 374 studies were initially retrieved. Most studies were classified as having poor quality and significant risk of bias. A total of 538 individuals with animal hoarding were evaluated. These individuals were predominantly middle-aged, unmarried women who lived alone in urban areas. Most of their residences had unsanitary conditions. Recidivism rates varied from 13-41%. Cats and dogs were the main hoarded species, mostly acquired through unplanned breeding, and disease, injury, behavioral problems, and a lack of hygiene were characreristic of their condition. Animal carcasses were found in up to 60% of the properties. Conclusion: Animal hoarding is a complex condition that requires urgent attention. More research is necessary to develop effective strategies that can save community resources, improve animal and human welfare, and prevent recidivism.

Common rituals in obsessive-compulsive disorder and implications for treatment: A mixed-methods study.

Obsessive-compulsive disorder (OCD) is characterized by engagement in rituals that serve to obtain certainty and prevent feared outcomes. Exposure and response prevention is most effective when rituals are resisted, yet existing self-report measures of OCD limit identification of the full range of possible rituals, and little is known about how rituals might cluster together and predict worsened severity and poorer treatment outcomes. In a retrospective sample of 641 adult patients who received intensive OCD treatment, the present study used a mixed-methods approach to (a) identify and validate treatment provider-identified rituals using the Yale-Brown Obsessive-Compulsive Scale, (b) identify clustering patterns of rituals, and (c) examine the impact of these clusters on severity and treatment outcomes. Sixty-two discrete rituals clustered into eight higher order ritual clusters: avoidance, reassurance, checking, cleaning/handwashing, just right, rumination, self-assurance, and all other rituals. At admission, reassurance predicted greater intolerance of uncertainty (IU) and rumination predicted less OCD severity. Only one ritual cluster-just right-predicted treatment outcomes; patients with just right rituals had worse IU at discharge and significantly longer length of treatment (average 7.0 days longer). Clinical observation can identify more nuanced and individualized rituals than self-report assessment alone. Patients presenting with just right rituals may benefit less from treatment focused on harm avoidance and habituation; instead, treatment should be tailored to the idiosyncrasies of incompleteness and not just the right experiences.

Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders guidelines for the treatment of adult obsessive-compulsive disorder. Part I: pharmacological treatment

Objectives: To summarize evidence-based pharmacological treatments and provide guidance on clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The American Psychiatric Association (APA) guidelines for the treatment of OCD (2013) were updated with a systematic review assessing the efficacy of pharmacological treatments for adult OCD, comprising monotherapy with selective serotonin reuptake inhibitors (SSRIs), clomipramine, serotonin and norepinephrine reuptake inhibitors (SNRIs), and augmentation strategies with clomipramine, antipsychotics, and glutamate-modulating agents. We searched for the literature published from 2013-2020 in five databases, considering the design of the study, primary outcome measures, types of publication, and language. Selected articles had their quality assessed with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association (ACC/AHA). Results: We examined 57 new studies to update the 2013 APA guidelines. High-quality evidence supports SSRIs for first-line pharmacological treatment of OCD. Moreover, augmentation of SSRIs with antipsychotics (risperidone, aripiprazole) is the most evidence-based pharmacological intervention for SSRI-resistant OCD. Conclusion: SSRIs, in the highest recommended or tolerable doses for 8-12 weeks, remain the first-line treatment for adult OCD. Optimal augmentation strategies for SSRI-resistant OCD include low doses of risperidone or aripiprazole. Pharmacological treatments considered ineffective or potentially harmful, such as monotherapy with antipsychotics or augmentation with ketamine, lamotrigine, or N-acetylcysteine, have also been detailed.

Individuals with problem gambling and obsessive-compulsive disorder learn through distinct reinforcement mechanisms.

Obsessive-compulsive disorder (OCD) and pathological gambling (PG) are accompanied by deficits in behavioural flexibility. In reinforcement learning, this inflexibility can reflect asymmetric learning from outcomes above and below expectations. In alternative frameworks, it reflects perseveration independent of learning. Here, we examine evidence for asymmetric reward-learning in OCD and PG by leveraging model-based functional magnetic resonance imaging (fMRI). Compared with healthy controls (HC), OCD patients exhibited a lower learning rate for worse-than-expected outcomes, which was associated with the attenuated encoding of negative reward prediction errors in the dorsomedial prefrontal cortex and the dorsal striatum. PG patients showed higher and lower learning rates for better- and worse-than-expected outcomes, respectively, accompanied by higher encoding of positive reward prediction errors in the anterior insula than HC. Perseveration did not differ considerably between the patient groups and HC. These findings elucidate the neural computations of reward-learning that are altered in OCD and PG, providing a potential account of behavioural inflexibility in those mental disorders.
