Depression and anxiety have unique contributions to somatic complaints in depression, irritable bowel syndrome and inflammatory bowel diseases
Bibliographic record
Abstract
OBJECTIVE: In this study we aim to investigate the effects of somatic and related symptoms (SARS), alexithymia, hypochondriasis, anxiety and depression on patients with major depressive disorder, irritable bowel syndrome, inflammatory bowel disease which are the representative diseases of brain gut axis (BGA).METHOD: Sex and age similar groups of participants with major depressive disorder (MDD) (n = 102), irritable bowel syndrome (IBS) (n = 51), inflammatory bowel diseases (IBDs) (n = 54), and control group (n = 67) were included into this study. Depression and IBS were diagnosed according to DSM-5 and ROME 4 criteria, respectively. IBDs were established according to endoscopic, histological, and radiographic investigations. In all participants, somatic and related symptoms were evaluated by self-report scales including Bradford Somatic Inventory (BSI), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Whiteley Index (WI), The 20-item Toronto Alexithymia Scale (TAS-20), Somatosensory Amplification Scale (SAS).RESULTS: BSI, BDI, BAI, WI, TAS-20 and SAS scores were found to be highest in patients with MDD; scores of patients with IBS and IBDs were similar but higher than the control group. Gastrointestinal somatic symptoms including nausea, stomach burning, abdominal ache and stomach swelling were observed in more than half of the patients with MDD. The most common extra-intestinal somatic symptoms were, headache and neck pain and/or tension, and leg pain in IBS patients. However leg pain, weakness and lack of energy, and neck pain/tension were highest in IBDs patients. While the strongest correlation determined was between the BSI and anxiety scores in MDD (p < .001, r = .688) and IBS group; (p < .001, r = .51), in IBDs patients, BSI scores were more significantly correlated with depressive scores instead of anxiety (p < .001, r = .712 vs. r = .705, p < .001).CONCLUSION: Our study demonstrates that SARS are commonly observed in the representative diseases of BGA. Extra-intestinal somatic symptoms are common in IBS, and IBDs, and also gastrointestinal somatic symptoms are common in patients with MDD. Assessment of somatic and related symptoms is quite important in the context of BGA.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
