Since the introduction of parental leave in Sweden a more gender-equal division of such leave has been targeted. In 1995 one month was reserved for each parent, implying that the month was forfeited if not used by the same parent. A second month was reserved in 2002. In 2008, a gender equality bonus was introduced, meaning that tax credits were given to parents who shared the leave equally. This study investigates the effects of these reforms on parental leave use by means of a difference-in-difference approach with parents of children born just before and just after the introduction of each reform. We use register data from the Swedish Social Insurance Agency, which include all parents residing in Sweden. The results indicate a strong effect on parental leave use resulting from the introduction of the first reserved month, a more modest but clear effect resulting from the second reserved month and, so far, no effect resulting from the gender equality bonus. Possible interpretations of the results are that (1) reserved time may be more effective than an economic bonus, (2) change from low levels of use may be easier and (3) reforms may matter most when they are first introduced.

In accordance with the monoamine hypothesis, a deficit in brain norepinephrine and dopamine exists in patients with depressive illness. Moreover, the brains of these patients use an energy source other than glucose, a situation that is normalized following the acute pharmacological blockade of the norepinephrine transporter with the tricyclic antidepressant, desipramine.

This study unequivocally demonstrates elevated sympathetic nerve activity in patients with renovascular hypertension. The adrenergic overactivity may contribute to the blood pressure elevation and perhaps also to the high cardiovascular mortality in renovascular hypertension.

Both BEI and BRS convey prognostic information that may have clinical implications for patients with cardiovascular diseases in general.

Background-Using new, very high-resolution ultrasound biomicroscopy, we examined the thickness of artificial layers of silicone and intima thickness (IT) of radial and anterior tibial arteries in healthy subjects and in patients with vascular disease. Methods and Results-Silicone layers of varying thicknesses and mesenteric artery specimens obtained from 18 patients undergoing colectomy were measured by both ultrasound biomicroscopy (55 MHz) and morphometry. There was high correlation (rϾ0.9; PϽ0.0001) between IT and intima area versus ultrasound biomicroscopy. In 90 healthy subjects (aged between 10 and 90 years), radial and anterior tibial arterial IT and intima-media thickness were measured, as was carotid intima-media thickness in 56 of these subjects. Age was strongly related with both media thickness and IT of both peripheral arteries. Correlations were found between carotid intima-media thickness and both radial and anterior tibial IT/intima-media thickness (rϭ0.44 to 0.53; PϽ0.0001). The IT-to-lumen diameter ratio increased with age and was larger at all ages in the anterior tibial artery (0.067Ϯ0.034) versus the radial artery (0.036Ϯ0.012; PϽ0.0001). A thicker radial intimal layer was found in patients with peripheral artery disease. Conclusion-This

Mediterranean-inspired diets have been shown to decrease cholesterol levels in patients with hypercholesterolaemia, who frequently exhibit endothelial dysfunction. The aims of the present study are to improve endothelial function by dietary intervention in healthy subjects with lipid levels representative of a Western population. Twenty-two healthy subjects (mean total cholesterol, 5.6 mmol/l) were given a Mediterranean-inspired diet rich in omega-3 fatty acids and sterol esters, but low in saturated fat, or an ordinary Swedish diet, for 4 weeks in a randomized cross-over study. The composition of the diets were: in the Swedish diet, 2090 kcal (where 1 kcal=4.184 kJ; 48% of energy from carbohydrate, 15% from protein and 36% from fat) and 19 g of fibre; in the Mediterranean-inspired diet, 1869 kcal (48% of energy from carbohydrate, 16% from protein, 34% from fat) and 40 g of fibre. After each dietary period, fasting blood lipids, insulin and glucose levels, as well as apo B (apolipoprotein B) and LDL (low-density lipoprotein) particle size, were analysed. Endothelial-dependent and -independent vasodilation was measured invasively by venous occlusion plethysmography, and arterial distensibility was assessed by echocardiography tracking. Fibrinolytic capacity across the forearm, as well as oxidative stress measured through urinary F(2)-isoprostane, were evaluated. Total, LDL- and apo B-cholesterol and triacylglycerol (triglyceride) concentrations were decreased by 17%, 22%, 16% and 17% respectively, after the Mediterranean-inspired diet compared with the Swedish diet ( P <0.05 for all). However, no differences in plasma concentrations of insulin and glucose and LDL particle size, endothelial function, arterial distensibility, fibrinolytic capacity or oxidative stress were detected. Treatment for 4 weeks with a Mediterranean-inspired diet decreased blood lipids in healthy individuals with a low-risk profile for cardiovascular disease. This beneficial effect was not mirrored in vascular function or oxidative stress evaluation.

A MID reduces the number of platelets and leukocytes and VEGF concentrations in healthy subjects. This may be linked to higher serum concentrations of n-3 fatty acids, which promote a favorable composition of phospholipids.
