Context: Animal and human studies suggest that programing of the hypothalamic-pituitary-adrenal (HPA) axis may be involved in the development of obesity, but human studies of biological indicators of HPA axis activity are lacking. We studied the association between levels of the stress hormone cortisol during pregnancy and overweight offspring during childhood into adolescence.', 'Salivary samples from 655 Danish pregnant women with singleton pregnancies (1989-1991) were collected once in the morning and once in the evening in their second and third trimester. We followed the offspring from two to 16 years of age with at least one measurement of height and weight, and classified their body mass index into overweight and normal weight. The adjusted relative difference in median salivary cortisol (with 95% confidence interval (CI)) during pregnancy (the four samples), in second and third trimester (morning and evening samples) between overweight and normal weight offspring was estimated. Furthermore, the adjusted median ratio between morning and evening maternal salivary cortisol level was estimated for normal weight and overweight children. All the analyses were stratified into the equal age groups: 2-6, 7-11, and 12-16 years.', 'We found non-significant higher maternal cortisol levels during pregnancy in offspring that were overweight at the age of 2-6, 7-11 and 12-16 years than in normal weight peers; adjusted relative difference in median salivary cortisol 11% (95% CI: -2; 25), 6% (95% CI: -7; 20), and 9% (95% CI: -4; 24), respectively. A statistically significantly higher level of maternal cortisol was found in the second trimester in 2-6-year-old and 12-16-year-old overweight offspring; relative difference 19% (95% CI: 3; 37), and 20% (95% CI: 3; 41), respectively. The median ratio between morning and evening maternal salivary cortisol level was similar for overweight and normal weight children; e.g. at age 2-6 years in third trimester 4.31 (95% CI: 4.05; 4.60)nmol/l and 4.28 (95% CI: 3.60; 5.09)nmol/l, respectively (P=0.93).
Answer: Our findings suggest a relatively consistent association between pregnancy cortisol levels and overweight offspring, especially in the second trimester.

Context: A patient with a suspected cervical spine injury may be at risk for secondary neurologic injury when initially placed and repositioned to the center of the spine board.', 'We sought to determine which centering adjustment best limits cervical spine movement and minimizes the chance for secondary injury.', 'Using five lightly embalmed cadaveric specimens with a created global instability at C5-C6, motion sensors were anchored to the anterior surface of the vertebral bodies. Three repositioning methods were used to center the cadavers on the spine board: horizontal slide, diagonal slide, and V-adjustment. An electromagnetic tracking device measured angular (degrees) and translation (millimeters) motions at the C5-C6 level during each of the three centering adjustments. The dependent variables were angular motion (flexion-extension, axial rotation, lateral flexion) and translational displacement (anteroposterior, axial, and medial-lateral).', 'The nonuniform condition produced significantly less flexion-extension than the uniform condition (p\xa0=\xa00.048). The horizontal slide adjustment produced less cervical flexion-extension (p\xa0=\xa00.015), lateral bending (p\xa0=\xa00.003), and axial rotation (p\xa0=\xa00.034) than the V-adjustment. Similarly, translation was significantly less with the horizontal adjustment than with the V-adjustment; medial-lateral (p\xa0=\xa00.017), axial (p\xa0<\xa00.001), and anteroposterior (p\xa0=\xa00.006).
Answer: Of the three adjustments, our team found that horizontal slide was also easier to complete than the other methods. The horizontal slide best limited cervical spine motion and may be the most helpful for minimizing secondary injury based on the study findings.

Context: Intravascular volume loss from ischemia-reperfusion (IR) injury is a major clinical concern. We hypothesize that angiotensin II decreases IR-mediated microvascular fluid leak via the angiotensin II type 2 receptor in a cAMP dependent manner. We therefore sought to determine hydraulic permeability after IR of venules treated with 1) angiotensin II, 2) angiotensin II and cAMP synthesis inhibitor, and 3) angiotensin II and an angiotensin II type 2 receptor antagonist.', 'Rat mesenteric post-capillary venules were micro-cannulated to measure hydraulic permeability (L(p)). IR was achieved by placing animals in a 5% oxygen environment and preventing venular flow, after which blood flow was allowed to resume. L(p) was measured after IR and treatment with 1) angiotensin II (20 nm), 2) angiotensin II (20 nm) + cAMP synthesis inhibitor (DDA,10uM), and 3) angiotensin II (20 nm) + type 2 receptor antagonist (PD-123319, 300 mum) (n=6 in each group).', 'Compared with the seven-fold increase in L(p) because of IR alone: 1) angiotensin II attenuated the seven-fold increase by 50% (P<0.005), 2) cAMP inhibition did not change the effect of angiotensin II on leak, and the type 2 receptor antagonist completely blocked the effects of angiotensin II on IR mediated leak.
Answer: Treatment with angiotensin II attenuated increases in hydraulic permeability because of IR by 50%. Inhibition of cAMP synthesis did not change the effect of angiotensin II on IR mediated leak, and angiotensin II type 2 receptor inhibition completely blocked the effects of angiotensin II. These results indicate that angiotensin II decreases IR induced leak via the angiotensin II type 2 receptor in a cAMP independent manner. A better understanding of mediators that reduce intravascular fluid loss from IR-induced microvascular dysfunction may help clinicians treat uncontrolled fluid extravasation that occurs during shock and sepsis.
