- BackgroundTo examine the effects of gastric bypass surgery on health-related quality of life (HRQoL) in obese patients with type 2 diabetes, and to investigate their experiences of life adjustments using quantitative and qualitative methods.MethodsThirteen patients with type 2 diabetes and obesity, (body mass index, BMI > 30 kg/m2), participating in a randomized clinical trial, completed this sub-study. HRQoL was evaluated before, and at 6 months and 2 years after gastric bypass surgery, using the RAND- 36-item health survey. At 2 years, interviews for in-depth analysis of HRQoL changes were performed.ResultsSignificant improvement was observed from baseline to 6 months for 2 of the eight health concepts, general health, and emotional well-being. At 2 years, improvements were also seen in physical functioning, energy/fatigue, as well as sustained improvements in general health and emotional well-being. Multiple regression analyses showed mostly non-significant associations between the magnitude of decrease in weight, BMI, and HbA1c during follow-up and improvement in HRQoL. The analyses from qualitative interviews supported a common latent theme “Finding a balance between the experience of the new body weight and self-confidence”.ConclusionsThe improved HRQoL after gastric bypass surgery in obese patients with type 2 diabetes was not explained specifically by the magnitude of weight loss, but rather by the participants achieving a state of union between body and consciousness.

- Bariatric surgery is the most medically and cost-effective treatment for adults with obesity and type 2 diabetes mellitus (T2DM). Our findings suggest initial improvements in health-related quality of life that may decline as support from follow-up care ends. How patients experience long-term support is not well described. This study therefore aimed to investigate how adults with previous T2DM perceived different sources of support 2 years after bariatric surgery. In this qualitative study individual interviews were conducted with 13 adults (10 women) 2 years after surgery. Using thematic analysis, one overarching theme (compiling complementary elements of support after gastric-bypass surgery), four themes and nine subthemes emerged. The results show that support was given and received from various sources, support needs varied over time depending on where the patient was in the process and that the sources of support were complementary. To conclude, our results show that support needs change in adults who have undergone bariatric surgery. Long-term professional and day-to-day support from family and other networks are essential and complementary elements of support. Health care staff should consider these findings, especially during the early follow-up period.

- Neuropeptide S (NPS) receptor (NPSR1) polymorphisms are associated with enteral dysmotility and inflammatory bowel disease (IBD). This study investigated the role of NPS in conjunction with nitrergic mechanisms in the regulation of intestinal motility and mucosal permeability. In rats, small intestinal myoelectric activity and luminal pressure changes in small intestine and colon, along with duodenal permeability were studied. In human intestine, NPS and NPSR1 were localized by immunostaining. Pre- and postprandial plasma NPS was measured by ELISA in healthy and active IBD humans. Effects and mechanisms of NPS were studied in human intestinal muscle strips. In rats, NPS 100-4000 pmol/kg·min had effects on the small intestine and colon. Low doses of NPS increased myoelectric spiking (p<0.05). Higher doses reduced spiking and prolonged the cycle length of the migrating myoelectric complex, reduced intraluminal pressures (p<0.05-0.01) and increased permeability (p<0.01) through NO-dependent mechanisms. In human intestine, NPS localized at myenteric nerve cell bodies and fibers. NPSR1 was confined to nerve cell bodies. Circulating NPS in humans was tenfold below the ~0.3 nmol/l dissociation constant (Kd) of NPSR1, with no difference between healthy and IBD subjects. In human intestinal muscle strips pre-contracted by bethanechol, NPS 1-1000 nmol/l induced NO-dependent muscle relaxation (p<0.05) that was sensitive also to tetrodotoxin (p<0.01). In conclusion, NPS inhibits motility and increases permeability in neurocrine fashion acting through NO in the myenteric plexus in rats and humans. Aberrant signaling and up-regulation of NPSR1 could potentially exacerbate dysmotility and hyperpermeability by local mechanisms in gastrointestinal functional and inflammatory reactions.
