Effectiveness of a dry-land resistance training program on strength, power, and swimming performance in paralympic swimmers.

This study evaluated the effectiveness of a dry-land resistance training program in Paralympic swimmers to increase swimming power and strength measures, and how these changes affect swimming performance. Seven elite-level Paralympic swimmers (1 man and 6 women; age: 19.4 ± 6.

Is the risk of lung cancer reduced among eczema patients?

Persons with a history of eczema have been shown to have a reduced risk of lung cancer, but the evidence has been inconclusive because of the small size of previous studies and their limited ability to control for confounding by smoking. The objective of this study was to determine the role of eczema in relation to lung cancer while overcoming the limitations of previous investigations. Study subjects included 2,854 cases and 3,116 population and hospital controls recruited during 1998-2001 from 16 areas in the Czech Republic, Hungary, Poland, Romania, Russia, Slovakia, and the United Kingdom.

Stage at diagnosis is a key explanation of differences in breast cancer survival across Europe.

We used multiple regression models to assess the influence of disease stage at diagnosis on the 5-year relative survival of 4,478 patients diagnosed with breast cancer in 1990-1992. The cases were representative samples from 17 population-based cancer registries in 6 European countries (Estonia, France, Italy, Netherlands, Spain and UK) that were combined into 9 regional groups based on similar survival. Five-year relative survival was 79% overall, varying from 98% for early, node-negative (T1N0M0) tumours; 87% for large, node-negative (T2-3N0M0) tumours; 76% for node-positive (T1-3N+M0) tumours and 55% for locally advanced (T4NxM0) tumours to 18% for metastatic (M1) tumours and 69% for tumours of unspecified stage.

The Liverpool Lung Project: a molecular epidemiological study of early lung cancer detection.

Lung cancer is the major cause of death from neoplastic disease in the world, and even with politically-motivated smoking cessation campaigns throughout Europe, the disease remains the major cause of death. The development of molecular epidemiological population-based research into early lung cancer detection, such as the Liverpool Lung Project (LLP), may provide a way forward. This is the first major molecular epidemiological study of detection of early lung cancer.

A T2517C polymorphism in the GSTM4 gene is associated with risk of developing lung cancer.

The human Mu class Glutathione S-Transferases is a family of genes encoding phase II detoxifying enzymes thus playing a significant role in the detoxification of potential carcinogens. While there are many contradicting reports on the association of GSTM1 polymorphisms and cancer development, no studies exist to date describing polymorphisms in GSTM4. We have identified a new C-T polymorphism in intron 6 of the GSTM4 gene (T2517C, Genebank sequence accession number X68677) and termed the allele carrying T at this position allele *A and the allele carrying C, allele *B.
