Abstract
Insulin action in the human brain modulates eating behaviour, whole-body metabolism and body fat distribution1,2. In particular, brain insulin action increases whole-body insulin sensitivity, but these studies were mainly performed in lean men3,4. Here we investigate metabolic and hypothalamic effects of brain insulin action in women with a focus on the impact of menstrual cycle ( ClinicalTrials.gov registration: NCT03929419 ).Eleven women underwent four hyperinsulinemic-euglycemic clamps, two in the follicular phase and two in the luteal phase. Brain insulin action was introduced using nasal insulin spray5-7 and compared to placebo spray in a fourfold crossover design with change in glucose infusion rate as the primary endpoint. Here we show that during the follicular phase, more glucose has to be infused after administration of nasal insulin than after administration of placebo. This remains significant after adjustment for blood glucose and insulin. During the luteal phase, no significant influence of brain insulin action on glucose infusion rate is detected after adjustment for blood glucose and insulin (secondary endpoint). In 15 other women, hypothalamic insulin sensitivity was assessed in a within-subject design by functional magnetic resonance imaging with intranasal insulin administration8. Hypothalamus responsivity is influenced by insulin in the follicular phase but not the luteal phase.Our study therefore highlights that brain insulin action improves peripheral insulin sensitivity also in women but only during the follicular phase. Thus, brain insulin resistance could contribute to whole-body insulin resistance in the luteal phase of the menstrual cycle.

Abstract
BACKGROUND AND OBJECTIVE This prospective, sham-controlled, randomized, cross-over study (NCT03637075), was designed to test the hypothesis that spinal cord stimulation (SCS) for the treatment of pain can also improve glucose metabolism and insulin sensitivity when compared to sham stimulation. METHODS Ten non-diabetic participants (5 females, mean age 48.8 years) who had an SCS system implanted for the treatment of chronic neuropathic pain were studied. Whilst applying a hyperinsulinemic-euglycemic clamp, sham-stimulation and tonic stimulation were performed for 45 min (n=4) or 60 min (n=6) in each case randomly. The insulin sensitivity index and pain levels were determined. A second investigation, BurstDR stimulation was also conducted and the result was compared to that of sham stimulation (cross-over design). RESULTS The insulin sensitivity improved significantly under the tonic stimulation when compared to the sham stimulation (p=0.037). BurstDR stimulation independently did not lead to a significantly improved insulin sensitivity compared to that after sham stimulation (p=0.16). We also examined the pain during the test and found no significant difference between sham and tonic stimulation (p=0.687). CONCLUSION The results of this study show that tonic stimulation used for the treatment of pain could also improve glucose metabolism and insulin sensitivity. Further investigations are required to investigate the clinical relevance of the role of glucose metabolism in diabetic chronic pain participants and its underlying mechanisms.

Abstract
Animal studies suggest that insulin action in the brain is involved in the regulation of peripheral insulin sensitivity. Whether this holds true in humans is unknown. Using intranasal application of insulin to the human brain, we studied the impacts of brain insulin action on whole-body insulin sensitivity and the mechanisms involved in this process. Insulin sensitivity was assessed by hyperinsulinemic-euglycemic glucose clamp before and after intranasal application of insulin and placebo in randomized order in lean and obese men. After insulin spray application in lean subjects, a higher glucose infusion rate was necessary to maintain euglycemia compared with placebo. Accordingly, clamp-derived insulin sensitivity index improved after insulin spray. In obese subjects, this insulin-sensitizing effect could not be detected. Change in the high-frequency band of heart rate variability, an estimate of parasympathetic output, correlated positively with change in whole-body insulin sensitivity after intranasal insulin. Improvement in whole-body insulin sensitivity correlated with the change in hypothalamic activity as assessed by functional magnetic resonance imaging. Intranasal insulin improves peripheral insulin sensitivity in lean but not in obese men. Furthermore, brain-derived peripheral insulin sensitization is associated with hypothalamic activity and parasympathetic outputs. Thus, the findings provide novel insights into the regulation of insulin sensitivity and the pathogenesis of insulin resistance in humans.
