Abstract

ED-71 is a potent analog of active vitamin D, 1,25 (OH) (2)D(3), bearing a hydroxypropoxy substituent at the 2beta-position. In ovariectomized rats, ED-71 prevented the reduction in bone mass and strength of lumber spine without causing hypercalcemia. From those results, it was suggested that ED-71 preferentially enhances bone formation with less effects on intestinal calcium absorption. In osteoporotic patients, oral daily administration of ED-71 (0.25, 0.5, 0.75 and 1.0 microg) for 6 months increased bone mineral density (BMD) at L(2-4) in a dose-dependent manner. ED-71 also exhibited a dose-depend suppression of urinary deoxypyridinoline with no significant reduction in serum osteocalcin. These results demonstrate that ED-71 can effectively increase bone mass without causing hypercalcemia, and suggest that ED-71 can be a promising candidate for the treatment of osteoporosis with prominent effect on bone formation.

[Preparation and structural study of NH(4)Gd(PO(3))(4) and NH(4)GdP(4)O(12)].

Ammonium gadolinium polyphosphate, NH(4)Gd(PO(3))(4), (I), and ammonium gadolinium cyclotetraphosphate, NH(4)GdP(4)O(12), (II), were synthesized by flux growth with excess (NH(4))(2)HPO(4). In (I), the PO(4) tetrahedra share vertices to produce corrugated ribbons along the c direction, while in (II) they form P(4)O(12) rings arranged in layers perpendicular to the c axis. In both structures, isolated GdO(8) polyhedra link the phosphate anions into a three-dimensional framework with channels containing the NH(4)(+) cations. The Gd and N atoms are located in general positions in (I) and on twofold axes in (II).

[High-dose atorvastatin or normal-dose simvastatin in treatment of patients with coronary heart disease (IDEAL trial)--secondary publication].

In the IDEAL trial, almost 9,000 patients with coronary heart disease were treated, after randomisation, with atorvastatin, 80 mg daily, or simvastatin, 20 or 40 mg daily, for 4.8 years. The LDL cholesterol level was 0.6 mmol/l lower in the atorvastatin group, a smaller difference than expected, and the 11% reduction in the primary end point (myocardial infarction, cardiac arrest, coronary death) in this group was not statistically significant (p = 0.07). In contrast, several secondary end points, one of which was the primary end point plus stroke, occurred statistically significantly less often in the atorvastatin group.

[Centralisation of pancreatic resection: a systematic review and evaluation in the Netherlands].

OBJECTIVE: To analyse the volume-outcome effect of pancreatic surgery by means of a systematic review, and to determine the effect of the ongoing plea for centralisation of pylorus-preserving pancreaticoduodenectomy in the Netherlands. DESIGN: Systematic review and retrospective evaluation. METHOD: A systematic search for studies comparing hospital mortality rates after pancreatic resection in high- and low-volume hospitals was conducted. The studies were independently assessed regarding design, inclusion criteria, threshold value for high and low volume and primary hospital mortality outcome. Data were obtained from the Dutch nation-wide registry on the mortality outcome of pancreaticoduodenectomy in 1994-2003. Hospitals were divided into 4 categories based on the number of pancreaticoduodenectomies performed. The effect of the ongoing plea for centralisation was analysed. RESULTS: Twelve observational studies comprising a total of 19,688 patients were included. Because the studies were too heterogeneous to allow a meta-analysis, a qualitative analysis was performed. The relative risk of dying in a high-volume hospital compared with a low-volume hospital was between 0.07 and 0.76 and was inversely proportional to the arbitrarily defined volume cut-off values. Various analyses conducted over a to-year period in the Netherlands reported mortality rates of 14-17% in hospitals that performed fewer than 5 pancreaticoduodenectomies per year, compared with rates of 0.0-3.50 degrees h in hospitals that performed more than 24 pancreaticoduodenectomies per year. The percentage of patients undergoing surgery in hospitals with a volume less than ro pancreaticoduodenectomies per year was 57% in 2000-2003 (454/792), compared with 65% (280/428) in 1994-1995. CONCLUSION: This systematic review provided evidence of an inverse relationship between hospital volume and mortality after pancreaticoduodenectomy and confirmed the value of centralisation of this procedure in high-volume hospitals. The 10-year-long plea of the Dutch surgical community for quality assessment and, if necessary, centralisation has not resulted in a reduction in mortality rates after pancreatic resection or a change in referral patterns in The Netherlands.
