- Background: There is sound evidence for the role of gastrointestinal infections in the development of postinfectious irritable bowel syndrome (PI-IBS), but understanding the interaction between mental factors and the infection remains incomplete. This study aims to (i) assess the occurrence of PI-IBS in a cohort of patients with self-reported travelers' diarrhea (TD), (ii) assess risk factors for PI-IBS development, and (iii) investigate the prognosis of PI-IBS after 1 year. Methods: Patients consulting the travel clinic at the University Hospital Tuebingen, Germany (in 2009 and 2010) were identified from records and questioned in follow-ups in 2011 and 2012. We used the Rome III modular questionnaire to assess IBS, the Hospital Anxiety and Depression Scale to assess anxiety and depression, and the Patient Health Questionnaire to assess somatization. Key Results: We identified 529 eligible subjects from the clinical records. Of 135 subjects (age: 36.6 ± 14.6 years, 58.5% female) included in the study sample 6.7% (95% CI 3.0-11.1) had PI-IBS. We found more females (88.9% vs 56.3%, p = 0.08) and younger age subjects (mean 29.3 vs 37.1 years, p = 0.02) among the PI-IBS subjects. A multivariable regression model revealed vomiting at baseline and high somatization scores as strong and independent PI-IBS risk factors. One year later PI-IBS occurrence decreased to 3.3% (three cases of 90). Conclusions & Inferences: Our findings underline the close linkage of mental and somatic processes for the manifestation of PI-IBS. Screening for psychiatric comorbidities in patients with severe gastrointestinal infections may allow identifying groups at high risk for PI-IBS.

- NeuroGUT is a EU-funded initial training network (ITN) of 14 research projects in neurogastroenterology that have employed an equal number of early-stage researchers. Neurogut trainees haveamong other activitiesattended an international conference on irritable bowel syndrome (IBS) in Bologna in 2016 and were asked to critically review and evaluate the current knowledge on IBS for their respective research activities, and to state what they were missing. Most appreciated were the topics brain imaging of gut activity, the role of the gut microbiota, the pharmacology of gut functions, the IBS-IBD interrelation, the new Rome IV criteria, the role of gas, and the placebo response in functional disorders. Missed were more detailed coverage of high-resolution manometry, functional brain imaging, advanced systems medicine approaches and bioinformatics technology, better sub-classification of IBS patients, and the development of disease biomarkers, extended at the molecular (genetic/epigenetic, proteonomic) level. They summarize that despite excellent specialized research, there is a gap open that should be filled with systems medicine. For this, it would be necessary that medical research learns even more from the data sciences and other basic disciplines, for example, information technology and system biology, and also welcomes a change in paradigm that enhances open sharing of data, information, and resources.

- Irritable bowel syndrome (IBS) is a functional gastrointestinal disease with a high population prevalence. The disorder can be debilitating in some patients, whereas others may have mild or moderate symptoms. The most important single risk factors are female sex, younger age and preceding gastrointestinal infections. Clinical symptoms of IBS include abdominal pain or discomfort, stool irregularities and bloating, as well as other somatic, visceral and psychiatric comorbidities. Currently, the diagnosis of IBS is based on symptoms and the exclusion of other organic diseases, and therapy includes drug treatment of the predominant symptoms, nutrition and psychotherapy. Although the underlying pathogenesis is far from understood, aetiological factors include increased epithelial hyperpermeability, dysbiosis, inflammation, visceral hypersensitivity, epigenetics and genetics, and altered brain-gut interactions. IBS considerably affects quality of life and imposes a profound burden on patients, physicians and the health-care system. The past decade has seen remarkable progress in our understanding of functional bowel disorders such as IBS that will be summarized in this Primer.

- <b><i>Background:</i></b> Placebo and nocebo effects occur in clinical or laboratory medical contexts after administration of an inert treatment or as part of active treatments and are due to psychobiological mechanisms such as expectancies of the patient. Placebo and nocebo studies have evolved from predominantly methodological research into a far-reaching interdisciplinary field that is unravelling the neurobiological, behavioural and clinical underpinnings of these phenomena in a broad variety of medical conditions. As a consequence, there is an increasing demand from health professionals to develop expert recommendations about evidence-based and ethical use of placebo and nocebo effects for clinical practice. <b><i>Methods:</i></b> A survey and interdisciplinary expert meeting by invitation was organized as part of the 1st Society for Interdisciplinary Placebo Studies (SIPS) conference in 2017. Twenty-nine internationally recognized placebo researchers participated. <b><i>Results:</i></b> There was consensus that maximizing placebo effects and minimizing nocebo effects should lead to better treatment outcomes with fewer side effects. Experts particularly agreed on the importance of informing patients about placebo and nocebo effects and training health professionals in patient-clinician communication to maximize placebo and minimize nocebo effects. <b><i>Conclusions:</i></b> The current paper forms a first step towards developing evidence-based and ethical recommendations about the implications of placebo and nocebo research for medical practice, based on the current state of evidence and the consensus of experts. Future research might focus on how to implement these recommendations, including how to optimize conditions for educating patients about placebo and nocebo effects and providing training for the implementation in clinical practice.
