Clinical guidelines for the use of lifestyle-based mental health care in major depressive disorder: World Federation of Societies for Biological Psychiatry (WFSBP) and Australasian Society of Lifestyle Medicine (ASLM) taskforce.

OBJECTIVES: The primary objectives of these international guidelines were to provide a global audience of clinicians with (a) a series of evidence-based recommendations for the provision of lifestyle-based mental health care in clinical practice for adults with Major Depressive Disorder (MDD) and (b) a series of implementation considerations that may be applicable across a range of settings. METHODS: Recommendations and associated evidence-based gradings were based on a series of systematic literature searches of published research as well as the clinical expertise of taskforce members. The focus of the guidelines was eight lifestyle domains: physical activity and exercise, smoking cessation, work-directed interventions, mindfulness-based and stress management therapies, diet, sleep, loneliness and social support, and green space interaction. The following electronic bibliographic databases were searched for articles published prior to June 2020: PubMed, EMBASE, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Methodology Register), CINAHL, PsycINFO. Evidence grading was based on the level of evidence specific to MDD and risk of bias, in accordance with the World Federation of Societies for Biological Psychiatry criteria. RESULTS: Nine recommendations were formed. The recommendations with the highest ratings to improve MDD were the use of physical activity and exercise, relaxation techniques, work-directed interventions, sleep, and mindfulness-based therapies (Grade 2). Interventions related to diet and green space were recommended, but with a lower strength of evidence (Grade 3). Recommendations regarding smoking cessation and loneliness and social support were based on expert opinion. Key implementation considerations included the need for input from allied health professionals and support networks to implement this type of approach, the importance of partnering such recommendations with behaviour change support, and the need to deliver interventions using a biopsychosocial-cultural framework. CONCLUSIONS: Lifestyle-based interventions are recommended as a foundational component of mental health care in clinical practice for adults with Major Depressive Disorder, where other evidence-based therapies can be added or used in combination. The findings and recommendations of these guidelines support the need for further research to address existing gaps in efficacy and implementation research, especially for emerging lifestyle-based approaches (e.g. green space, loneliness and social support interventions) where data are limited. Further work is also needed to develop innovative approaches for delivery and models of care, and to support the training of health professionals regarding lifestyle-based mental health care.

An epidemiological study of externally determined and self-identified mental and physical disability across the spectrum of bipolar disorders.

BACKGROUND: Studies exploring disability in bipolar disorder (BD) have primarily assessed clinical samples of full-threshold BD-I and BD-II alongside so-called objective criteria such as unemployment or receipt of government disability payments. This study extends research on disability by examining externally determined and self-identified disability in a community sample and by including subthreshold BD (BDS). METHODS: Data were extracted from the USA Collaborative Psychiatric Epidemiology Surveys about individuals who met recognized criteria for BD-I, BD-II and BDS who had completed self-ratings of physical and mental disability, comorbidities, and health risk factors (e.g., obesity). Rates of disability were estimated, and logistic regression analyses were used to determine demographic and clinical variables associated with externally determined and self-identified of disability. RESULTS: Of 408 individuals who met eligibility criteria (BD-I = 100; BD-II=104; BDS=204), 35% met criteria for externally determined disability, about 40% self-reported mental disability and about 23% self-reported physical disability. The odds were three-fold (Odds Ratio (OR): 3.05; 95% Confidence Intervals (CI): 1.69, 5.53) that someone with self-identified physical disability would meet criteria for externally determined disability, but associations with mental disability were non-significant (OR: 1.06; 95% CI: 0.63, 1.80). Regression analyses demonstrated that mental disability was associated with being a current or past smoker and physical disability was associated with BD-I. LIMITATIONS: the adequacy of the assessments of disability and definition of BDS can be questioned. CONCLUSIONS: Future clinical and community studies need to consider both externally determined and self-identified disability across the entire Bd spectrum.

Emotion regulation and Residual Depression Predict Psychosocial Functioning in Bipolar Disorder: Preliminary Study / Regulación de las emociones y la depresión residual predicen el funcionamiento psicosocial en el trastorno bipolar: estudio preliminar

This study explores the predictive value of various clinical, neuropsychological, functional, and emotion regulation processes for recovery in Bipolar Disorder. Clinical and demographic information was collected for 27 euthymic or residually depressed BD participants. Seventy one percent of the sample reported some degree of impairment in psychosocial functioning. Both residual depression and problems with emotion regulation were identified as significant predictors of poor psychosocial functioning. In addition, to residual depression, the results of the current study introduce a variable of emotion dysregulation to account for poor psychosocial functioning among BD populations. Improving emotion regulation strategies, in particular, concentration and task accomplishment during negative emotional states could have important consequences for improving overall psychosocial functioning among this population, helping to reduce both the economic burden and high costs to personal wellbeing associated with BD.

Este estudio explora el valor predictivo de los diversos procesos de regulación clínicos, neuropsicológicos, funcionales y emocionales para la recuperación en el Trastorno Bipolar. La información clínica y demográfica se recogió de 27 participantes de TB eutímicos o residualmente deprimidos. Setenta y uno por ciento de la muestra reportó algún grado de deterioro en el funcionamiento psicosocial. Tanto la depresión residual y problemas con la regulación de las emociones fueron identificados como predictores significativos de mal funcionamiento psicosocial. Además de la depresión residual, los resultados del presente estudio introducen una variable de disregulación emocional para dar cuenta del pobre funcionamiento psicosocial en las poblaciones de TB. La mejora de las estrategias de regulación emocional, en particular, la concentración y la realización de tareas durante los estados emocionales negativos podrían tener consecuencias importantes para mejorar el funcionamiento psicosocial global en esta población ayudando a reducir tanto la carga económica y los altos costos para el bienestar personal asociado con TB.

Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for Clinical and Research Applications: recommendations of the International RDC/TMD Consortium Network* and Orofacial Pain Special Interest Group†.

AIMS: The original Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I diagnostic algorithms have been demonstrated to be reliable. However, the Validation Project determined that the RDC/TMD Axis I validity was below the target sensitivity of ≥ 0.70 and specificity of ≥ 0.95. Consequently, these empirical results supported the development of revised RDC/TMD Axis I diagnostic algorithms that were subsequently demonstrated to be valid for the most common pain-related TMD and for one temporomandibular joint (TMJ) intra-articular disorder. The original RDC/TMD Axis II instruments were shown to be both reliable and valid. Working from these findings and revisions, two international consensus workshops were convened, from which recommendations were obtained for the finalization of new Axis I diagnostic algorithms and new Axis II instruments. METHODS: Through a series of workshops and symposia, a panel of clinical and basic science pain experts modified the revised RDC/TMD Axis I algorithms by using comprehensive searches of published TMD diagnostic literature followed by review and consensus via a formal structured process. The panel's recommendations for further revision of the Axis I diagnostic algorithms were assessed for validity by using the Validation Project's data set, and for reliability by using newly collected data from the ongoing TMJ Impact Project-the follow-up study to the Validation Project. New Axis II instruments were identified through a comprehensive search of the literature providing valid instruments that, relative to the RDC/TMD, are shorter in length, are available in the public domain, and currently are being used in medical settings. RESULTS: The newly recommended Diagnostic Criteria for TMD (DC/TMD) Axis I protocol includes both a valid screener for detecting any pain-related TMD as well as valid diagnostic criteria for differentiating the most common pain-related TMD (sensitivity ≥ 0.86, specificity ≥ 0.98) and for one intra-articular disorder (sensitivity of 0.80 and specificity of 0.97). Diagnostic criteria for other common intra-articular disorders lack adequate validity for clinical diagnoses but can be used for screening purposes. Inter-examiner reliability for the clinical assessment associated with the validated DC/TMD criteria for pain-related TMD is excellent (kappa ≥ 0.85). Finally, a comprehensive classification system that includes both the common and less common TMD is also presented. The Axis II protocol retains selected original RDC/TMD screening instruments augmented with new instruments to assess jaw function as well as behavioral and additional psychosocial factors. The Axis II protocol is divided into screening and comprehensive self report instrument sets. The screening instruments' 41 questions assess pain intensity, pain-related disability, psychological distress, jaw functional limitations, and parafunctional behaviors, and a pain drawing is used to assess locations of pain. The comprehensive instruments, composed of 81 questions, assess in further detail jaw functional limitations and psychological distress as well as additional constructs of anxiety and presence of comorbid pain conditions. CONCLUSION: The recommended evidence-based new DC/TMD protocol is appropriate for use in both clinical and research settings. More comprehensive instruments augment short and simple screening instruments for Axis I and Axis II. These validated instruments allow for identification of patients with a range of simple to complex TMD presentations.

Development and validation of a screening checklist for temporomandibular disorders.

AIMS: To develop and validate a short screening tool for temporomandibular disorders (TMD) from the comprehensive Research Diagnostic Criteria for TMD (RDC/TMD) assessment. METHODS: Complete RDC/TMD assessments of four subject groups (96 TMD; 102 dental pain; 68 headache; 115 no-pain patients) were compared. Classification tree and multiple logistic regression analyses were utilized to develop the tool. To test external validity, a further 54 TMD and 51 non-TMD subjects whose diagnoses had been established by RDC/TMD assessment were reassessed with the new screening tool. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and likelihood ratios (LRs) were calculated for the screening tool in the validation set of subjects. RESULTS: A short TMD checklist was developed. This screening instrument had sensitivity of 94.4% (95% confidence intervals [CI], 84.9% to 98.1%), specificity of 94.1% (95% CI, 84.1% to 98%), PPV of 94.4% (95% CI, 84.9% to 98.1%), NPV of 94.1% (95% CI, 84.1% to 98%), and positive and negative LRs of 16.056 (95% CI, 5.346 to 48.219) and 0.059 (95% CI, 0.02 to 0.178) in an independent validation set. CONCLUSION: A short TMD screening checklist with high validity has been developed. This checklist may have good utility in general practice as a primary screening tool for TMD.

Therapeutic mechanism in seasonal affective disorder: do fluoxetine and light operate through advancing circadian phase?

In the context of Lewy's phase delay hypothesis, the present study tested whether effective treatment of winter Seasonal Affective Disorder (SAD) is mediated by advancing of circadian phase. Following a baseline week, 78 outpatients with SAD were randomized into 8 weeks of treatment with either fluoxetine and placebo light treatment or light treatment and placebo pill. Depression levels were measured on the Ham17+7 and the BDI-II, and circadian phase was estimated on the basis of daily sleep logs and self-reported morningness-eveningness. Among the 61 outpatients with complete data, both treatments were associated with significant antidepressant effect and phase advance. However, pre- and post-treatment comparisons found that the degree of symptom change did not correlate with the degree of phase change associated with treatment. The study therefore provides no evidence that circadian phase advance mediates the therapeutic mechanism in patients with SAD. Findings are discussed in terms of the limitations of the circadian measures employed.
