Background: Chronic abdominal pain is a common problem in childhood.Purpose: Due to the prevalence of functional abdominal pain (FAP) and the importance of probiotics, this study aimed to compare the ability of 2 probiotics to reduce and improve FAP in children.Methods: This open-label randomized clinical trial included 116 children aged 5–15 years with FAPP who met the ROME-4 criteria and were referred to the gastrointestinal clinic of Amir-Kabir Hospital in Arak in 2020–2021. The children were randomly allocated to receive polymicrobial probiotic (PMP group) or mono-strain probiotic (MSP group) once daily for 4 weeks. The standard Wong-Baker Faces scale was used to assess symptom severity.Results: Of the 116 subjects, 62 (53.5%) were boys; the mean participant age was 7.39 years (standard deviation, 3.4 years). A significant intergroup difference (<i>P</i>=0.003) was observed in pain severity; 10.34% of children in the PMP group had no pain, while all patients in the MSP group reported low-degree pain. There was no intergroup difference in mean pain score (<i>P</i>=0.466), but it decreased over time in both groups (<i>P</i>= 0.001).Conclusion: Although significantly more children were painless in the PMP versus MSP group, no significant intergroup difference in pain score was noted and symptom severity decreased in both groups. A future study with a placebo group is recommended to validate our findings. .

A chaotic simple jerk system (SJS) that belongs to systems with self-excited and hidden attractors is introduced in this paper. The dynamics of the proposed SJS is analytically and numerically investigated. Interestingly, the influence of the time delay on the proposed chaotic SJS is studied. In addition, the physical existence of self-excited and hidden chaotic attractors found in the proposed SJS and in the time-delayed form of SJSs (TDSJSs) are verified by using Orcard-PSpice software. Finally, chaos synchronization of identical, unidirectional, coupled, proposed chaotic TDSJSs is also reported.
