TASK DEFINITION: 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.
PROBLEM: We aimed at analyzing the frequency, clinical characteristics, and trends associated with the occurrence of diabetic ketoacidosis (DKA) at the onset of type 1 diabetes on the basis of long-term follow-up data.', 'A total of 106 pediatric diabetes centers in Germany and Austria participated in this study. Data from 14,664 patients with type 1 diabetes collected between 1995 and 2007 were suitable for evaluation. DKA was defined and classified according to the International Society for Pediatric and Adolescent Diabetes consensus guidelines.', 'DKA was observed in 21.1% of patients. The frequency of DKA, including the severe form, remained unchanged throughout the 13-year observation period. The frequency of DKA was particularly striking among children <5 years of age (26.5%).

PROBLEM: The hepatitis B virus X protein (HBx) plays critical roles in cell survival via modulation of signaling pathways. In our previous studies, we reported that HBx inhibited the growth of CCL13-HBx-stable cells (Chang-HBx cells) in vitro and tumor formation in vivo in CCL13-HBx-cell-injected nude mice; however, this inhibition mechanism is unclear.', 'To investigate the role of HBx in Wnt-3/beta-catenin signaling pathways, we focused on the key molecules GSK-3beta and beta-catenin, and analyzed by Western blotting and immunofluorescence staining.', 'Results indicated that following HBx induction, GSK-3beta activity was up-regulated, the expression and accumulation of beta-catenin in the nucleus were decreased, and cell proliferation was suppressed. Inhibition of GSK-3beta activity by pharmacological inhibitors rescued the expression and accumulation of beta-catenin in the nucleus and facilitated cell proliferation and growth following HBx induction. The localization of beta-catenin, which is involved in cell proliferation, and mediated by GSK-3beta activation was also demonstrated.

PROBLEM: To study the cure rate and 5 year results of laparoscopic burch colposuspension for stress urinary incontinence in Thai women.', 'Twenty one Thai women with stress urinary incontinence attending the gynecology clinic at King Chulalongkorn Memorial hospital were recruited. Pre operative clinical and urodynamic evaluation were done. They underwent Laparoscopic burch colposuspension between January - December 1998. The cure rate was evaluated by clinical and urodynamic examination.', 'The mean +/- SD of operative time, blood loss and hospital stay were 70 +/- 20 min, 140 +/- 30 ml and 1.6 +/- 0.5 days respectively. The complication rate was 19.1% (Bladder injuries 2 cases, voiding difficulties 1 case and de novo detrusor overactivity 1 case). The objective cure rate at 5 years was 76.2%.
