Prevalence of gastrointestinal symptoms and their association with psychological problems in youths.

BACKGROUND: Gastrointestinal symptoms and psychological problems are common in youths, which can negatively affect their lives on physical, mental, and social levels. This cross-sectional study aimed to determine the prevalence of gastrointestinal symptoms in youths and further explore their association with psychological problems. METHODS: Self-reported data on gastrointestinal symptoms and psychological problems in 692 sophomores who majored in education in a high vocational school and 310 recruits who were undergoing basic training in an army in China were retrospectively collected. The self-reported data included demographics, gastrointestinal symptoms, and Symptom Checklist 90 (SCL-90) used for the assessment of psychological problems. Gastrointestinal symptoms surveyed included nausea, emesis, abdominal pain, acid regurgitation, eructation, heartburn, anorexia, abdominal bloating, diarrhea, constipation, hematemesis, and hematochezia. Logistic regression analysis was performed to identify the independent risk factors associated with gastrointestinal symptoms. Odds ratios (ORs) with 95% confidence intervals (CI) were calculated. RESULTS: The prevalence of gastrointestinal symptoms was 36.7% (n=254) and 15.5% (n=48) in the sophomores and recruits, respectively. Participants with gastrointestinal symptoms had a significantly higher prevalence of total SCL-90 score beyond 160 than those without gastrointestinal symptoms in both sophomores (19.7% vs. 3.2%, P<0.001) and recruits (10.4% vs. 1.1%, P<0.001). Total SCL-90 score beyond 160 was independently associated with gastrointestinal symptoms in both sophomores (OR =5.467; 95% CI: 2.855-10.470; P<0.001) and recruits (OR =6.734; 95% CI: 1.226-36.999; P=0.028). CONCLUSIONS: Gastrointestinal symptoms may be common and strongly associated with psychological problems in youths. Prospective studies should be required to explore the impact of the correction of psychological problems on the improvement of gastrointestinal symptoms.

Intensive rTMS for treatment-resistant depression patients with suicidal ideation: An open-label study.

The advantages of intensive repetitive transcranial magnetic stimulation (rTMS) protocol are in the possible acute effect of the stimulation and in the possible reduction in the time required to achieve remission in depression. Here, we investigated the antidepressant effects and antisuicidal effects of a more intensive rTMS protocol for treatment-resistant depression (TRD) patients with suicidal ideation. Thirty-one outpatients were included in this study, including 22 military veterans and 9 non- militaries. The rTMS treatment consisted of 25 sessions, each session lasting 30 min (60 trains of 50 pulsations, 110 % resting motor threshold intensity) for a total of 3000 pulse. The total amount of stimulation (750,000 pulses) applied by our rTMS protocol was equivalent to that of a 5-week standard rTMS protocol. We found a significant effect of time on the 17-item Hamilton Depression Rating Scale (HAMD-17) scores and the Sheehan Disability Scale (SDS) scores. There was no difference in change in the HAMD-17 scores and SDS scores between the military veteran group and the non-military group between baseline and the week 4 assessment time point. The response rate of depression was 64.52 %, and the remission rate of depression was 51.61 % at day 5. 48.39 % and 35.48 % at week 4, respectively. All patients (100 %) met response criteria of suicidal ideation, and the remission rate was 87.09 % at day 5. The response rate was 83.87 % %, and the remission rate was 77.42 % at week 4. The accelerated high-dose rTMS treatment was well tolerated by all patients. Our intensive rTMS protocol is preliminarily safe and feasible. The TRD patients with suicidal ideation could benefit from much shorter exposure to this protocol with more efficacy in comparison with conventional rTMS protocol. In addition, intensive rTMS offers a promising treatment for military veteran populations.
