Nutrition education intervention for women with breast cancer: effect on nutritional factors and oxidative stress

OBJECTIVES

To assess the effect of a nutrition education intervention on nutritional factors and oxidative stress during treatment of breast cancer.

DESIGN

Nonrandomized clinical trial conducted in 2010-2011, including an evaluation at baseline and after 12 months.

PARTICIPANTS

Women from Brazil who had breast cancer, divided into an intervention group (IG) (n = 18) and comparison group (n = 75).

INTERVENTION

To increase intake of fruits and vegetables and reduce red and processed meats, via telephone and printed materials.

MAIN OUTCOME MEASURES

Food intake, anthropometry, and levels of lipid hydroperoxide, carbonyl proteins, reduced glutathione, and ferric reducing antioxidant power.

ANALYSES

Chi-square, Mann-Whitney or t tests for baseline data; Wilcoxon or paired t tests for intra-group outcomes, linear regression models, and Bonferroni multiplicity adjustment.

RESULTS

The researchers observed an increase in fruit and vegetable intake, reduction in red and processed meat intake, no change in body weight, and an increase in glutathione in the IG over the comparison group. However, after Bonferroni adjustment, only the consumption of fruits and vegetables and fruit was significantly higher in IG.

CONCLUSIONS AND IMPLICATIONS

This study presents improved dietary changes after a theory-driven nutrition education intervention. Although the sample size is small, it has proven to be clinically relevant.

Application of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry to the structure determination of medium and large macrocycles formed by palladium(0)-catalyzed allylation of arenesulfonamides, sulfamide, and cyanamide

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry allowed the direct determination of the extent of macrocyclic and linear oligomer formation in the palladium(0)-catalyzed allylation of highly acidic and non-nucleophilic arenesulfonamides, sulfamide, and cyanamide. Palladium-containing 15-membered-ring macrocyclic compounds gave unusual [M - H](+) ions besides [M + Na](+) and [M + K](+) adducts. Copyright 1999 John Wiley & Sons, Ltd.

[Quantitative analysis of lymphocyte and monocyte levels in patients after operations for breast cancer]

The much less than Quantigen T and B Cell Assay much greater than method is used to evaluate T and B lymphocyte levels, Nuls Cells and monocytes in the peripheral venous blood of patients surgically treated for breast cancer. The results obtained show a change in immune competent cell levels and temporary immune restoration of the immune response during treatment with immunostimulators.

Differences in the use of American Sign Language morphology by deaf children: implications for parents and teachers

Newport (1988) has noted differences in how American Sign Language (ASL) is used by the following three groups of deaf adults: those with deaf parents (native signers); those, with hearing parents, who learned ASL upon entering school at age 5 years (early signers); and those who learned to sign after puberty (late signers). The present study extends this research to children by investigating the use of morphological inflections in ASL by native and early signers. Thirty deaf children between ages 3 and 9 years were asked to sign a story in ASL. The videotaped stories were analyzed for morphological and contextual complexity. Qualitative differences were found between native and early signers on measures relating to the aspectual complexity of signs but not on measures relating to the complexity of the utterance. Implications of these differences are discussed in terms of communication at home and ASL use in the classroom.
