Brain-derived neurotrophic factor (BDNF), a member of the neurotrophin family, may play a critical role in many chronic pain conditions. The possible involvement of BDNF in the altered gut sensation in patients with irritable bowel syndrome (IBS) was investigated in the present study. ⋯ The increased expression of BDNF in colonic mucosa, together with the structural alterations of mucosal innervation, may contribute to the visceral hyperalgesia in IBS.

Gastric cancer is a major gastrointestinal malignancy for which targeted therapies are emerging as treatment options. This study sought to identify the most prevalent molecular targets in gastric cancer and to elucidate systematic patterns of exclusivity and co-occurrence among these targets, through comprehensive genomic analysis of a large panel of gastric cancers. ⋯ The study demonstrates the existence of five distinct gastric cancer patient subgroups, defined by the signature genomic alterations FGFR2 (9% of tumours), KRAS (9%), EGFR (8%), ERBB2 (7%) and MET (4%). Collectively, these subgroups suggest that at least 37% of gastric cancer patients may be potentially treatable by RTK/RAS directed therapies.

Upper gastrointestinal haemorrhage and deprivation: a nationwide cohort study of health inequality in hospital admissions.
Inequalities in health are well recognized in cardiovascular disease and cancer, but in comparison, we have minimal understanding for upper gastrointestinal bleeding. Since furthering our understanding of such inequality signposts preventable disease, we investigated in detail the association between upper gastrointestinal bleeding and socioeconomic status. ⋯ Both variceal and non-variceal haemorrhage hospitalization rates increased with deprivation, and there was a similar gradient in all areas of the country and in all age bands. The existence of such a steep gradient suggests that there are opportunities to reduce hospitalizations down to the low rates seen in the most affluent, and thus, there is the potential to prevent almost 10,000 admissions and over 1000 deaths a year.

The treatment of inflammatory bowel disease is becoming more complicated with new medications and new treatment paradigms. Although data are accumulating that the earlier use of immunomodulators and anti-tumor necrosis factor agents are more effective than the standard "step-up" pyramidal treatment algorithm, patients may not be comfortable with this more intensive therapeutic approach. The process of shared decision making engages patients in treatment decisions to optimize the chance that a chosen therapy matches their personal preferences for care. ⋯ Not all care decisions are preference-sensitive, and not all patients are interested in being part of a shared medical decision. The responsibility of the provider is to identify how much of a role patients want, and then determine which decisions need their input to provide the best patient-centered care. The overall goal is to involve patients in decisions so that they are educated about their options, confident in the plan, adherent to chosen therapy and ultimately have a better quality of life.
