Diurnal rythm of Nampt is gender and weight dependent.

RESEARCH AIM: Nicotinamide phosphoribosyltransferase (Nampt) is an adipocytokine that is elevated in obesity, type 2 diabetes and increased levels are associated with inflammatory processes. Nampt serum concentrations have been suggested to follow a diurnal rhythm peaking in the afternoon in lean males. However, no data exists regarding the effects of gender and body weight. MATERIAL AND METHODS: We measured Nampt serum levels over 24 h in a cohort of healthy individuals living with either normal weight or obesity. Furthermore, effects of meals, oral glucose tolerance test and physical exercise on Nampt concentrations were evaluated. Correlation analyses to other hormonal- and lab parameters and anthropometric measurements were performed. RESULTS: Nampt showed a diurnal rhythm with increased levels at daytime and a peak in the early afternoon. This diurnal rhythm was significant for all groups but obese males. The Nampt amplitude, measured both relatively and absolutely, was significantly higher in females than in males. Meals did not influence Nampt serum levels, whereas physical exercise and an OGTT did significantly influence Nampt serum levels. CONCLUSION: In conclusion, we found gender specific differences in Nampt amplitude and coefficient variation with both being higher in females. The circadian rhythm of Nampt was independent of gender in healthy lean individuals, whereas it was disturbed in men with obesity.

Parental expectations before and after 12-month experience with video consultations combined with regular outpatient care for children with type 1 diabetes: a qualitative study.

AIM: To explore parents' expectations of the perceived barriers to and benefits of 1 year of monthly video consultations combined with regular outpatient care of children with type 1 diabetes. METHODS: The Virtual Diabetes Outpatient Clinic for Children and Youth (VIDIKI) study was a controlled, multicentre, perennial study with 240 participants from northern Germany. Fifty-four qualitative interviews with parents were analysed using qualitative content analysis. Before the intervention, 30 interviews were conducted to assess parents' expectations, and after 1 year, 24 interviews evaluated the experienced benefits and barriers to video consultations. RESULTS: Four main topics were identified from parents' responses to the video consultation. The main advantages of the video consultation compared with standard care were a higher frequency of contact for optimized insulin dosing and saving time; difficulties with internet connections were identified as the main barrier. A feeling of increased confidence with respect to insulin dosing was directly associated with telemedicine. Digital prescriptions and meeting the same diabetologist in both outpatient and telemedical care were mentioned as important improvements. The majority of interviewees preferred intervals of 4-6 weeks between video consultations. CONCLUSION: The higher frequency of contact with the diabetes team was considered a great relief by parents of children with type 1 diabetes. Apart from the time savings and flexibility in appointments, the most important advantages were the higher frequency of contact leading to short-term therapy adjustments and an increase in the ability to adjust therapy independently.
