Higher prevalence of irritable bowel syndrome and greater gastrointestinal symptoms in obsessive-compulsive disorder.

Background: Anxiety and mood symptoms often co-occur with gastrointestinal problems, such as irritable bowel syndrome (IBS). The extent to which these relate to Obsessive-Compulsive Disorder (OCD) is unclear, despite anxiety being a prominent symptom of this disorder. The purpose of this analysis was to examine gastrointestinal symptoms in unmedicated, non-depressed adult OCD patients compared to age- and sex-matched community controls.

Prevalence of hoarding behaviours and excessive acquisition in users of online classified advertisements.

An estimated 2-6% of the general population is thought to suffer from clinically significant hoarding symptoms, with 80-90% engaging in excessive acquisition. Minimal research has examined the excessive acquisition component of hoarding disorder (HD). Many individuals with HD have limited insight into their condition and are reluctant to seek help, making prevalence estimates difficult to obtain.

The impact of history of exposure to abuse on outcomes after bariatric surgery: data from the Ontario Bariatric Registry.

Background: Studies worldwide have reported an increased prevalence of abuse histories among bariatric surgery candidates. The impact of abuse history on weight loss after surgery has not been examined in Canada.

Objectives: Determine the prevalence of abuse and its impact on postoperative outcomes in Ontario, Canada.

"WHAT'S BUGGING THE GUT IN OCD?" A REVIEW OF THE GUT MICROBIOME IN OBSESSIVE-COMPULSIVE DISORDER.

The gut microbiome has become a topic of major interest as of late, with a new focus specifically on psychiatric disorders. Recent studies have revealed that variations in the composition of the gut microbiota may influence anxiety and mood and vice versa. Keeping the concept of this bidirectional "microbiota-gut-brain" axis in mind, this review aims to shed light on how these findings may also be implicated in obsessive-compulsive disorder (OCD); potentially outlining a novel etiological pathway of interest for future research in the field.
