Role of a prudent breakfast in improving cardiometabolic risk factors in subjects with hypercholesterolemia : a randomized controlled trial
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background & Aims: It is unclear whether advising a prudent breakfast alone is sufficient to improve blood lipids and cardiometabolic risk factors in overweight hypercholesterolemic subjects.Methods: The aim of the present study was to investigate whether a prudent low-fat breakfast (PB) rich in dietary fiber lowers low-density lipoprotein cholesterol (LDL-C) and other cardiometabolic risk factors in subjects with elevated LDL-cholesterol levels. In a parallel, controlled, 12-week study, 79 healthy overweight subjects (all regular breakfast eaters) were randomly allocated to a group that received a PB based on Nordic foods provided ad libitum or a control group that consumed their usual breakfast. The PB was in accordance with national and Nordic nutrition recommendations and included oat bran porridge with low-fat milk or yogurt, bilberry or lingonberry jam, whole grain bread, low-fat spread, poultry or fatty fish, and fruit.Results: No differences were found in LDL-C, blood lipids, body weight, or glucose metabolism, but SAD, plasma CRP, and TNF-R2 were lower during PB compared with controls (p<0.05). In the overall diet, PB increased dietary fiber and b-glucan compared with controls (p<0.05).Conclusions: Advising a prudent breakfast for 3 months did not influence blood lipids, body weight, or glucose metabolism but reduced markers of visceral fat and inflammation.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background:Preeclampsia (PE) is associated with increased risk for cardiovascular disease later in life. Whether, the artery wall layer dimensions differ between PE and normal pregnancy is unclear. The aim of this study was to estimate if women with PE have different common carotid artery wall layer dimensions than women with normal pregnancy, both during pregnancy and about one year postpartum.Methods:By using high-frequency (22MHz) ultrasound (Collagenoson, Meudt, Germany) separate estimates of the common carotid artery intima and media layers were obtained and the I/M ratio was calculated in women with PE (n=55 during pregnancy and n=48 at postpartum) and with normal pregnancy (n=65 during pregnancy and n=59 at postpartum). Thick intima, thin media and a high intima/media ratio are signs of less healthy artery wall and vice versa.Results:In women with PE, the intima was thicker (0.18 } 0.03 vs. 0.11 } 0.02; p < .001), the media was thinner (0.47 } 0.12 vs. 0.55 } 0.14; p = .001) and the I/M ratio was higher (0.41 } 0.14 vs. 0.20 } 0.05; p < .001) compared to women with normal pregnancy. Further, for changes from pregnancy to postpartum, both for PE and normal pregnancy, the intima and the I/M ratio had improved but still significantly higher in women with PE than in women with normal pregnancy.Conclusion:In women with PE, we found a thicker intima, thinner media and a higher I/M ratio compared to women with normal pregnancy, indicating a more negatively affected artery wall layer dimensions. Persisting negative effects of PE on artery wall at postpartum, despite improvement of artery wall layers compared to values during pregnancy, indicates a permanent damage of the vascular system in this group of women.

Endotracheal Suction a Reopened Problem
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- During mechanical ventilation, patients are connected to the ventilator by an endotracheal tube. The tube needs to be cleaned from mucus by suction, which can cause negative effects such as lung collapse, hypoxemia and desaturation. These can be avoided by preoxygenation, change of ventilator settings, use of closed suction systems and recruitment manoeuvres. The aim of the study was to investigate the effects of endotracheal suction during different ventilator settings and by different suction methods. A method to reverse side effects was investigated.In anaesthetized pigs, the effect of suction during volume and pressure-controlled ventilation was investigated, and the effect of different suction systems and catheter sizes were compared. Suction efficacy was investigated in a bench study. The effect of recruitment manoeuvre added after suction, i.e. post-suction recruitment manoeuvre was evaluated.Endotracheal suction causes lung volume loss leading to impaired gas exchange, an effect that is more severe in pressure-controlled ventilation than in volume-controlled ventilation. When 14 French suction catheters were used more side effects were found compared to 12 French catheters, but no difference was found between open and closed suction system in pressure-controlled ventilation. Open suction system was more effective to remove mucus compared to closed system. Post-suction recruitment manoeuvre restored the side effects after the first recruitment when it was applied directly after suction.In conclusion, open endotracheal suction causes impairment in gas exchange and lung mechanics, and more so in pressure-controlled than in volume-controlled mode. These changes can be minimized if smaller suction catheters are used. A post-suction recruitment manoeuvre applied directly after suction restores lung function. It is obvious that the recruitment manoeuvre should be added directly after suction, because if the manoeuvre is delayed and the lung is collapsed and left collapsed, it will be more difficult to recruit the lung.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- In this chapter we discuss the role of small free-standing subcontractors in such a production system, in terms of production and the creation of a new supplier park, using the case of the Goteborg final assembly plant of the Volvo Car Corporation and its domestic suppliers. The impact of putting pressure on first tier suppliers to locate close to the final assembly plant is first discussed in theoretical terms of forces of concentration and dispersion operating on different tiers of the production hierarchy. From this, five main issues concerning supply chains, subcontractors and supplier parks will be discussed: • The role of small and medium sized branch plants and independent SMEs in the ongoing restructuring process within the automotive industry. What are the prospects for competition with larger firms for first tier contracts?
