Cardiology
(1) Assessment of Treatment with Lisinopril and Survival. A trial comparing the effects of high to low doses of Zestril®/lisinopril on morbidity and mortality (M&M) in patients with CHF.
 
Logistics
Randomised, double-blind, parallel-group; 3164 patients.
 
Conclusion
Combined risk of mortality and hospitalisation was 12% lower in the high-dose group.
 
(2) Acolysis during Treatment of Lesions Affecting Saphenous Vein Bypass Grafts. A trial evaluating the use of percutaneous CUT for managing thrombosed coronary SVGs.
 
Primary endpoint
Composite (minimum) lumen diameter <30%, TIMI-3 flow, 30-day freedom from MACE; was achieved in 54% of CUT patients vs 73% of abciximab patients.
 
Logistics
Randomised, controlled, multicentre; 191 patients (92 CUT, 89 abciximab followed by PCI).
 
Conclusion
CUT should not be used during PCI of thrombosed SVGs.

Oncology
Adjuvant Tamoxifen Longer Against Shorter. A trial that asked the optimal duration of adjuvant tamoxifen (a SERM) therapy in women with early breast CA.
 
Logistics
Randomised, international; 13752 enrolled.
 
Sports medicine
Athletes’ Training and Learning to Avoid Anabolic Steroids. A multi-component school-based program for male high school athletes (age 13 to 19), which capitalises on team-centred dynamics and uses positive peer pressure and role modelling to reduce the use of anabolic steroids, alcohol and other drugs.
 
Intervention
A highly scripted 10-session curriculum.
 
Results
New substance use and anabolic steroid use decreased by 50%; drinking and driving decreased by 25%; decreased use of drugs, alcohol and performance-enhancing agents; increased exercise and nutrition.

Syntactic analysis of Lithuanian scholastic geographical atlases showed that in the legends of maps the cartographic signs usually are correctly semantically differentiated (Fig.
Pragmatic analysis showed that the graphic load of atlases published by different publishing-houses varies; the distribution of cartographic signs is uneven (Fig.
Analysis revealed that the load (by visual evaluation) of more than a half of all analysed scholastic geographical atlases is acceptable (Fig.
The research also showed that the Lithuanian scholastic geographical atlases are not overloaded with information (Fig.
