- Background Lack of physician involvement in quality improvement threatens the success and sustainability of quality improvement measures. It is therefore important to assess physicians ' interests and opportunities to be involved in quality improvement and their experiences of such participation, both in hospital and general practice. Methods A cross-sectional postal survey was conducted on a representative sample of physicians in different job positions in Norway in 2019. Results The response rate was 72.6% (1513 of 2085). A large proportion (85.7%) of the physicians wanted to participate in quality improvement, and 68.6% had actively done so in the last year. Physicians' interest in quality improvement and their active participation was significantly related to the designated time for quality improvement in their work-hour schedule (p < 0.001). Only 16.7% reported time designated for quality improvement in their own work hours. When time was designated, 86.6% of the physicians reported participation in quality improvement, compared to 63.7% when time was not specially designated. Conclusions This study shows that physicians want to participate in quality improvement, but only a few have designated time to allow continuous involvement. Physicians with designated time participate significantly more. Future quality programs should involve physicians more actively by explicitly designating their time to participate in quality improvement work. We need further studies to explore why managers do not facilitate physicians ' participation in quality improvement.

- OBJECTIVELong-term diabetes leads to severe peripheral, autonomous, and central neuropathy in combination with clinical gastrointestinal symptoms. The brain-gut axis thus expresses a neurophysiological profile, and heart rate variability (HRV) can be correlated with clinical gastrointestinal symptoms.RESEARCH DESIGN AND METHODSFifteen healthy volunteers and 15 diabetic patients (12 with type 1 diabetes) with severe gastrointestinal symptoms and clinical suspicion of autonomic neuropathy were included. Psychophysics and evoked brain potentials were assessed after painful rectosigmoid electrostimulations, and brain activity was modeled by brain electrical source analysis. Self-reported gastrointestinal symptoms (per the Patient Assessment of Upper Gastrointestinal Disorder Severity Symptom Index) and quality of life (SF-36 Short Form Survey) were collected.RESULTSDiabetic patients had autonomous neuropathy, evidenced by decreased electrocardiographic R-R interval (P = 0.03) and lower HRV (P = 0.008). Patients were less sensitive to painful stimulation (P = 0.007), had prolonged latencies of evoked potentials (P 0.001), and showed diminished amplitude of the N2-P2 component in evoked potentials (P = 0.01). There was a caudoanterior shift of the insular brain source (P = 0.01) and an anterior shift of the cingulate generator (P = 0.01). Insular source location was associated with HRV assessments (all P < 0.02), and the shift (expressed in mm) correlated negatively with physical health (P < 0.001) and positively with nausea (P = 0.03) and postprandial fullness (P = 0.03). Cingulate source shift was correlated negatively with physical health (P = 0.005) and positively with postprandial fullness (P 0.001).CONCLUSIONSThis study provides evidence for interaction between autonomic neuropathy and peripheral nervous degeneration, as well as changes in dipole sources in diabetic patients with gastrointestinal symptoms. The findings may lead to improved treatment modalities targeting pharmacological neuroprotection or neuromodulation.

- Background Gastroparesis, a chronic disorder of abnormal gastric motility, is common in patients with diabetes mellitus. A synthetic, selective ghrelin receptor agonist, TZP-101, is in clinical development for treatment of gastroparesis. This double-blind, randomized, placebo-controlled study evaluated the safety and efficacy of multiple TZP-101 doses in patients with moderate to severe symptomatic diabetic gastroparesis. Methods Patients were admitted to the hospital and adaptively randomized to receive a single 30-min intravenous infusion of 20, 40, 80, 160, 320, or 600 μg kg−1 TZP-101, (n = 57) or placebo, (n = 19) for four consecutive days. Symptoms were evaluated daily with the patient-rated Gastroparesis Cardinal Symptom Index (GCSI) and Gastroparesis Symptom Assessment (GSA). Clinicians rated gastroparesis symptoms on treatment day 4. Key Results The 80 μg kg−1 dose was identified as the most effective dose. On day 4, there was statistically significant improvement compared with placebo in the severity of GCSI Loss of Appetite and Vomiting scores for that dose group (P = 0.034 and P = 0.006). In addition, at the 80 μg kg−1 dose, the proportion of patients with at least 50% improvement in vomiting score was significantly different (P = 0.019) compared with placebo. Meal-related GSA scores for Postprandial fullness were significantly improved in the 80 μg kg−1 TZP-101 group compared with placebo (P = 0.012). Clinicians rated the 80 μg kg−1 group better improved than placebo for overall symptom assessment (P = 0.047). Safety profiles were similar in the placebo and TZP-101 groups and all doses were well-tolerated.

- Diabetes mellitus (DM) is associated with structural and functional changes of the central nervous system. We used electroencephalography (EEG) to assess resting state cortical activity and explored associations to relevant clinical features. Multichannel resting state EEG was recorded in 27 healthy controls and 24 patients with longstanding DM and signs of autonomic dysfunction. The power distribution based on wavelet analysis was summarized into frequency bands with corresponding topographic mapping. Source localization analysis was applied to explore the electrical cortical sources underlying the EEG. Compared to controls, DM patients had an overall decreased EEG power in the delta (1-4 Hz) and gamma (30-45 Hz) bands. Topographic analysis revealed that these changes were confined to the frontal region for the delta band and to central cortical areas for the gamma band. Source localization analysis identified sources with reduced activity in the left postcentral gyrus for the gamma band and in right superior parietal lobule for the alpha 1 (8-10 Hz) band. DM patients with clinical signs of autonomic dysfunction and gastrointestinal symptoms had evidence of altered resting state cortical processing. This may reflect metabolic, vascular or neuronal changes associated with diabetes.

- Introduction It has been shown that patients with type 1 diabetes mellitus and gastrointestinal (GI) symptoms have abnormal processing of sensory information following stimulation in the oesophagus. In order to find less invasive stimuli to study visceral afferent processing and to further elaborate the gut–brain network in diabetes, we studied brain networks following rectal electrical stimulations. Methods Twelve type 1 diabetes patients with GI symptoms and twelve healthy controls were included. A standard ambulatory 24-h electrocardiography was performed. 122-channel-evoked brain potentials to electrical stimulation in the rectum were recorded. Brain source-connectivity analysis was done. GI symptoms were assessed with the gastroparesis cardinal symptom index and quality of life (QOL) with SF-36. Any changes in brain source connectivity were correlated to duration of the disease, heart beat-to-beat intervals (RRs), clinical symptoms, and QOL of the patients. Results Diabetic patients with GI symptoms showed changes relative to controls in the operculum–cingulate network with the operculum source localized deeper and more anterior (P ⩽ 0.001) and the cingulate source localized more anterior (P = 0.03). The shift of operculum source was correlated with the duration of the disease, severity of GI symptoms, and decreased RR (P < 0.05). The shift of the cingulate source was correlated with the mental QOL (P = 0.04). In healthy controls, the contribution of the cingulate source to the network was higher than the contribution of the operculum source (P ⩽ 0.001), whereas in patients the contribution of the two sources was comparable. Conclusion This study gives further evidence for CNS involvement in diabetes. Since network reorganizations were correlated to GI symptoms, irregularities of rectal-evoked potentials can be viewed as a proxy for abnormal bottom-up visceral afferent processing. The network changes might serve as a biomarker for disturbed sensory visceral processing of GI symptoms in diabetes patients.

- In a clinical setting, diabetic autonomic complications (cardiac, gastrointestinal, urogenital, etc.) are often handled as separate entities. We investigated rectal sensitivity to heat, mechanical distension, and electrical stimulations in 20 patients with diabetes and symptoms of gastroparesis, to evaluate the extent of visceral neuronal damage. Furthermore, to evaluate the relation between the nervous structures we examined gastric emptying and cardiac autonomic function with the hypothesis being an association between these. We found that 60% of patients had delayed gastric empting. Rectal hyposensitivity was a general finding as they tolerated 67% higher thermal, 42% more mechanical, and 33% higher electrical current intensity compared to healthy controls. In patients, most heart rate variability parameters were reduced; they reported significantly more gastrointestinal symptoms and a reduced quality of life in all SF-36 domains. Shortened RR interval correlated with reduced rectal temperature sensitivity, and gastric retention rate was negatively associated with symptoms of nausea and vomiting. To conclude, in these patients with signs and symptoms of diabetic gastroparesis, rectal sensitivity was reduced, and heart rate variability was impaired. Thus, we suggest regarding diabetic autonomic neuropathy as a diffuse disorder. Symptoms of widespread autonomic dysfunction and sensory disorders should be expected and treated in these patients.
