  • Left ventricular remodelling changes without concomitant loss of myocardial fat after long-term dietary intervention
  • 2016
  • Ingår i: International Journal of Cardiology. - : Elsevier BV. - 0167-5273 .- 1874-1754. ; 216, s. 92-96

    • Background: Accumulation of myocardial triglycerides (MTG) is associated with impaired left ventricular (LV) remodelling and function in obese and diabetic subjects. The role of MTG accumulation in development of heart failure in this group of patients is unknown. Short-term studies suggest that diets that lead to weight loss could mobilize MTG, with a favourable effect on cardiac remodelling. In a 24-month, randomized, investigator-blinded study, we assessed the effect of two different diets and subsequent weight loss on cardiac function and MTG in postmenopausal women. Methods: Sixty-eight healthy postmenopausal women with body mass index [BMI] >= 27 kg/m(2) were randomized to an ad libitum Palaeolithic diet (PD) or a Nordic Nutrition Recommendation (NNR) diet for 24 months. Morphology, cardiac function, and MTG levels were measured using magnetic resonance (MR) scanning, including proton spectroscopy at baseline and 6 and 24 months. Results: Despite mean weight losses of 4.9 (1.0) kg (NNR) and 7.8 (1.1) kg (PD), the MTG content did not change over time (p = 0.98 in the NNR and p = 0.11 in the PD group at 24 months). Reduced left ventricular mass was observed in both diet groups over 24 months. Blood pressure was reduced at 6 months, but returned to baseline levels at 24 months. End diastolic volume, stroke volume, and cardiac output decreased over time. No differences between diet groups were observed. Conclusions: Diet intervention and moderate weight loss over 24 months improved LV remodelling but did not alter MTG levels in overweight/obese postmenopausal women. (C) 2016 Elsevier Ireland Ltd.

  • Project Avatar Developing a Distributed Mobile Phone Game
  • 2006
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Team Avatar, as the members of Project Avatar have come to be known by, is a group of 4th year computer science students at Uppsala University that have been developing a distributed mobile phone game during the fall of 2005. In this paper we describe the general design and environment of the result of Project Avatar - the game Three Crowns.

  • Attenuated Low-Grade Inflammation Following Long-Term Dietary Intervention in Postmenopausal Women with Obesity
  • 2017
  • Ingår i: Obesity. - : Wiley. - 1930-7381 .- 1930-739X. ; 25:5, s. 892-900
  • Tidskriftsartikel (refereegranskat)abstract
    • ObjectiveAbdominal fat accumulation after menopause is associated with low-grade inflammation and increased risk of metabolic disorders. Effective long-term lifestyle treatment is therefore needed. MethodsSeventy healthy postmenopausal women (age 605.6 years) with BMI 32.55.5 were randomized to a Paleolithic-type diet (PD) or a prudent control diet (CD) for 24 months. Blood samples and fat biopsies were collected at baseline, 6 months, and 24 months to analyze inflammation-related parameters. ResultsAndroid fat decreased significantly more in the PD group (P=0.009) during the first 6 months with weight maintenance at 24 months in both groups. Long-term significant effects (P<0.001) on adipose gene expression were found for toll-like receptor 4 (decreased at 24 months) and macrophage migration inhibitory factor (increased at 24 months) in both groups. Serum interleukin 6 (IL-6) and tumor necrosis factor levels were decreased at 24 months in both groups (P<0.001) with a significant diet-by-time interaction for serum IL-6 (P=0.022). High-sensitivity C-reactive protein was decreased in the PD group at 24 months (P=0.001). ConclusionsA reduction of abdominal obesity in postmenopausal women is linked to specific changes in inflammation-related adipose gene expression.
