Functional Nausea Is Not Just Nausea: A Multi-Center, Cross-Sectional Study of Children and Young Adults.

New evidencepediatricepidemiologyfunctional dyspepsia
Clinical takeawayWhen diagnosing pediatric patients ages 8-21 years with functional nausea, assess for comorbid abdominal pain disorders (e.g., functional dyspepsia, IBS), mental health conditions, and extra-intestinal symptoms, as FN rarely presents as isolated nausea.
ContextThis literature reports that functional nausea in pediatric populations is a distinct entity within disorders of gut-brain interaction, warranting further investigation.

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.

When Food Avoidance Meets Compatible Diagnostic Criteria: Avoidant/Restrictive Food Intake Disorder Features in Irritable Bowel Syndrome.

New evidenceIBSfunctional dyspepsiaepidemiologybiomarker
Clinical takeawayConsider screening IBS patients for DSM-5-compatible ARFID using validated tools like NIAS-Fr, particularly in those with depressive symptoms, severe IBS, or functional dyspepsia, to identify those at risk of medical/psychosocial impairment.
What it found33.4% of IBS patients met DSM-5-compatible ARFID criteria, defined by NIAS-Fr subscale cutoffs ('picky' ≥10, 'fear' ≥10, 'appetite' ≥9), medical/psychosocial impairment, and absence of eating disorder diagnosis, with depressive symptoms and IBS severity independently associated (Nagelkerke R2 = 0.203). Functional dyspepsia was prevalent in 60.4% of patients and associated with ARFID-like symptoms.
ContextRefines understanding of ARFID prevalence in IBS, distinguishing ARFID-like symptoms (47.5%) from DSM-5-compatible ARFID (33.4%), and highlights associations with depressive symptoms, IBS severity, and functional dyspepsia.

Diagnostic Value of the Anal Endoluminal Functional Luminal Imaging Probe for the Diagnosis of Anismus: An Exploratory Study.

Diagnosticartificial intelligencebiomarkerfunctional dyspepsia
Clinical takeawayConsider using anal EndoFLIP as an adjunctive diagnostic tool for anismus in patients with functional constipation and suspected dyssynergic defecation, particularly to rule out the condition. Note that the thresholds are exploratory and require external validation before clinical adoption.
What it foundA maximal absolute ΔCSA below 12.8 mm2 at 40 mL distension on anal EndoFLIP had 93% specificity and AUC 0.81 for diagnosing anismus in patients with functional constipation and suspected dyssynergic defecation.
ContextThis exploratory study introduces anal EndoFLIP as a potential diagnostic tool for anismus, complementing the current composite reference standard (anorectal manometry, surface electromyography, and defecography).

PTSD Is Associated With Severity of Upper GI Symptoms in Patients With Gastroparesis.

New evidencegastroparesis
Clinical takeawayConsider screening gastroparesis patients for PTSD using the PCL-5 (threshold >33) and addressing psychosocial factors in symptom management. Further exploration of trauma-focused therapy is suggested to assess its effects on improving symptoms.
What it found28% of gastroparesis patients screened positive for PTSD, which was associated with worse GI symptom severity (p < 0.01) but not gastric delay or accommodation.
ContextConfirms prior evidence linking PTSD to worse symptom severity in functional GI disorders and identifies reduced myoelectric activity in PTSD patients, but challenges assumptions about its impact on gastric motility.
