Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Weight-loss is a near societal obsession and many diet programs use significant calorie restriction including fasting/short term starvation to generate rapid effects. Fasting is also a well-recognized cause of immunosuppression especially within the innate immune system. In this study, we sought to determine if the IL-1 arm of the neuroimmune system was down-regulated by a 24h fast and how fasting might generate this effect.', 'Mice were allowed ad libitum access to food or had food withheld for 24h. Expression of the endogenous IL-1 antagonists, IL-1 receptor type 2 (IL-1R2), and IL-1 receptor antagonist (IL-1RA) was determined as were sickness behaviors before and after IL-1 administration.', 'Fasting markedly increased gene expression of IL-1R2 (83-fold in adipose tissue, 9.5-fold in liver) and IL-1RA (68-fold in liver). Fasted mice were protected from IL-1-induced weight-loss, hypoglycemia, loss of locomotor, and social anxiety. These protections were coupled to a large positive interaction of fasting and IL-1 on IL-1R2 gene expression in adipose tissue and liver (2.6- and 1.6-fold, respectively). Fasting not only increased IL-1RA and IL-1R2 protein 2.5- and 3.2-fold, respectively, in liver but also increased IL-1R2 1.8-fold in adipose tissue. Fasting, in turn, triggered a 2.4-fold increase in plasma free-fatty acids (FFAs) and a 2.1-fold increase in plasma corticosterone. Inhibition, of glucocorticoid action with mifepristone did not impact fasting-dependent IL-1R2 or IL-1RA gene expression. Administration of the FFA, palmitate, to mice increased liver IL-1R2 and IL-1RA gene expression by 14- and 11-fold, respectively.

Progression of pulmonary vascular disease limits heart transplantation for hypoplastic left heart syndrome (HLHS) to early infancy. Our objective was to assess the impact of bilateral pulmonary artery banding (PAB) on the operative courses of HLHS infants transplanted at ages older than 4 months.', 'Courses of all HLHS patients in our center who remained listed to age >or=120 days before heart transplantation were assessed. Patients undergoing transplantation after standard management (control group) were compared to patients having a prior pulmonary blood flow limiting procedure (PAB group).', 'Of 16 identified patients, one crossed over to stage I Norwood on day 185 and died post-operatively. Fifteen patients were transplanted at age >or=120 days (control group n=9, PAB group n=6). Four PAB patients had open PA band placement. Two PAB patients underwent experimental percutaneous bilateral internal pulmonary artery flow limiting device insertion. The PAB group mean age at banding was 141+/-54 days, and mean interval from PAB to transplant was 35+/-31 days (range 1.5-68 days). No differences in age at transplant, weight at transplant, warm graft ischemia time or total graft ischemia time were detected between groups. Mean times of mechanical ventilation (control 143+/-69h vs. PAB 44+/-13h), inhaled nitric oxide (control 126+/-70h vs. PAB 37+/-9h), inotropic support (control 171+/-64h vs. PAB 87+/-17h), intensive care unit (ICU) stay (control 8.3+/-2.7 days vs. PAB 4.5+/-1.4 days), and hospital stay (control 10.4+/-3.9 days vs. PAB 7.0+/-1.1 days) were all lower in the PAB group (P<0.05 all comparisons). Two control patients died, three required extracorporeal membrane oxygenation (ECMO), and six did not tolerate primary chest closure. No PAB patient died or required ECMO. All PAB patients tolerated primary chest closure. All PAB patients had widely patent branch pulmonary arteries with no re-interventions to date. All hospital survivors remain alive (mean follow-up, control 50.2 months, PAB 11.5 months).

Fracture risk in type 1 diabetes (T1D) is supposed to be underestimated by bone mineral density (BMD). Individuals with T1D had more prevalent fractures in a cross-sectional study. Serum levels of pentosidine, an advanced glycation end product, and poor glycaemic control were associated with prevalent fractures independent of BMD.', 'Type 1 diabetes (T1D) is associated with increased fracture risk. Bone mineral density (BMD) underestimates the risk of fractures in some individuals. The accumulation of advanced glycation end products (AGEs) impairs bone matrix and reduces bone strength.', 'In a cross-sectional study, 128 men and premenopausal women with T1D were evaluated. We compared traditional risk factors for fractures, BMD, parameters of bone metabolism and AGEs in individuals with and without prevalent fractures. An independent association of serum AGE levels with prevalent fractures was investigated.', 'Individuals with prevalent fractures exhibited a longer duration of T1D, higher HbA1c and more diabetic-related complications. BMD at the femoral neck (z-score -0.760.94 vs. -0.231.02; p=0.031) and total hip (z-score -0.540.93 vs. 0.111.11; p=0.017) was lower in those with prevalent fractures. Individuals with fractures had higher pentosidine levels (164.153.6 vs. 133.240.4; p=0.002). The levels of N--(carboxymethyl)-lysine (CML) and endogenous secretory receptor for AGEs (esRAGE) did not significantly differ. Multivariate logistic regression analysis adjusted for age, BMI, family history of fractures, smoking, vitamin D deficiency, BMD at lumbar spine, femoral neck and total hip identified pentosidine levels and HbA1c as independent factors associated with prevalent fractures (odds ratio 1.02, 95% CI 1.00-1.03/pmol/ml increase of pentosidine; p=0.008 and odds ratio 1.93, 95% CI 1.16-3.20 per percentage increase of HbA1c; p=0.011).
