Efficacy of a low FODMAP diet in irritable bowel syndrome: systematic review and network meta-analysis.

Gut 2021 Aug 10. Epub 2021 Aug 10.

Leeds Institute of Medical Research at St. James's, University of Leeds, Leeds, UK

Objective: A diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) is recommended for irritable bowel syndrome (IBS), if general lifestyle and dietary advice fails. However, although the impact of a low FODMAP diet on individual IBS symptoms has been examined in some randomised controlled trials (RCTs), there has been no recent systematic assessment, and individual trials have studied numerous alternative or control interventions, meaning the best comparator is unclear. We performed a network meta-analysis addressing these uncertainties. Read More

Dynamics of data-driven microstates in bipolar disorder.

J Psychiatr Res 2021 09 16;141:370-377. Epub 2021 Jul 16.

Department of Population Health Sciences, 610 Walnut Street, 707 WARF Building, University of Wisconsin, Madison, WI, 53706, USA; Department of Mathematics, Van Vleck Hall, 480 Lincoln Drive, University of Wisconsin, Madison, WI, 53706, USA. Electronic address:

Many of the existing models of mood in bipolar disorder can largely be divided into two camps, tracking mood as either a discrete or continuous variable. Both groups rely upon certain assumptions, with most considering only aggregate scores on clinical instruments. In this study, we propose a novel framework that combines elements from both discrete and continuous mood models, using a machine learning pipeline to detect subtle patterns across individuals.

Behavioural and physiological response to frustration in autistic youth: associations with irritability.

J Neurodev Disord 2021 07 19;13(1):27. Epub 2021 Jul 19.

Department of Child and Adolescent Psychiatry, Institute of Psychiatry, Psychology & Neuroscience, King's College London, London, UK.

Background: Irritability is a common and impairing occurrence in autistic youth, yet the underlying mechanisms are not well-known. In typically developing populations, differences in frustration response have been suggested as important driver of the behavioural symptoms of irritability. Research exploring the role of frustration response as a risk factor for irritability in autistic populations is limited and often uses parent report or observer ratings; objective measures of frustration response appropriate for use in autistic populations are required to advance the field.

Irritable Bowel Syndrome: Questions and Answers for Effective Care.

Am Fam Physician 2021 06;103(12):727-736

Mayo Clinic College of Medicine and Science, Rochester, MN, USA.

Irritable bowel syndrome (IBS) is a heterogeneous group of conditions related to specific biologic and cellular abnormalities that are not fully understood. Psychological factors do not cause IBS, but many people with IBS also have anxiety or depressed mood, a history of adverse life events, or psychosocial stressors. Physicians must understand the fears and expectations of patients and how they think about their symptoms and should also respond empathetically to psychosocial cues. Read More

Identifying the Inter-Domain Relations Among ODD, CD, and CU Traits in Preschool Children Using Network Analysis.

Res Child Adolesc Psychopathol 2021 10 14;49(10):1289-1301. Epub 2021 Jun 14.

University of Kentucky, Lexington, KY, 40506, USA.

Oppositional defiant disorder (ODD) and conduct disorder (CD) are two of the most common forms of disruptive behavior disorders during childhood. Callous-unemotional (CU) traits are an important factor in understanding the presentation of these externalizing forms of psychopathology. ODD, CD, and CU traits are highly related constructs, yet little work has examined how these externalizing forms of psychopathology are related at the domain level. Read More

Dynamics of amygdala connectivity in bipolar disorders: a longitudinal study across mood states.

Neuropsychopharmacology 2021 08 7;46(9):1693-1701. Epub 2021 Jun 7.

Laboratory for Behavioral Neurology and Imaging of Cognition, Department of Fundamental Neurosciences, University of Geneva, Geneva, Switzerland.

Alterations in activity and connectivity of brain circuits implicated in emotion processing and emotion regulation have been observed during resting-state for different clinical phases of bipolar disorders (BD), but longitudinal investigations across different mood states in the same patients are still rare. Furthermore, measuring dynamics of functional connectivity patterns offers a powerful method to explore changes in the brain's intrinsic functional organization across mood states. We used a novel co-activation pattern (CAP) analysis to explore the dynamics of amygdala connectivity at rest in a cohort of 20 BD patients prospectively followed-up and scanned across distinct mood states: euthymia (20 patients; 39 sessions), depression (12 patients; 18 sessions), or mania/hypomania (14 patients; 18 sessions).

The Role of Epigenomic Regulatory Pathways in the Gut-Brain Axis and Visceral Hyperalgesia.

Cell Mol Neurobiol 2021 May 31. Epub 2021 May 31.

Division of Gastroenterology and Hepatology, Department of Internal Medicine, University of Michigan, Ann Arbor, MI, USA.

The gut-brain axis (GBA) is broadly accepted to describe the bidirectional circuit that links the gastrointestinal tract with the central nervous system (CNS). Interest in the GBA has grown dramatically over past two decades along with advances in our understanding of the importance of the axis in the pathophysiology of numerous common clinical disorders including mood disorders, neurodegenerative disease, diabetes mellitus, non-alcohol fatty liver disease (NAFLD) and enhanced abdominal pain (visceral hyperalgesia). Paralleling the growing interest in the GBA, there have been seminal developments in our understanding of how environmental factors such as psychological stress and other extrinsic factors alter gene expression, primarily via epigenomic regulatory mechanisms.

The Irritable and Oppositional Dimensions of Oppositional Defiant Disorder: Integral Factors in the Explanation of Affective and Behavioral Psychopathology.

Child Adolesc Psychiatr Clin N Am 2021 07;30(3):637-647

Department of Psychological Sciences, University of Connecticut, 406 Babbidge Road, Storrs, CT 06269, USA.

Oppositional defiant disorder includes distinct but inseparable dimensions of chronic irritability and oppositional behavior. The dimensions have been identified in early childhood to adulthood, and show discriminant associations with internalizing and externalizing psychopathology. The introduction of disruptive mood dysregulation disorders and the requirements that it take precedence over oppositional defiant disorder diagnostically are not supported by evidence and introduce confusion about the structure and linkages of irritability and oppositional behavior, and obscure the importance of the behavioral dimension in explaining and predicting poor outcomes.
