CYP2D6 genotype and adjuvant tamoxifen: meta-analysis of heterogeneous study populations.

2013

The International Tamoxifen Pharmacogenomics Consortium was established to address the controversy regarding cytochrome P450 2D6 (CYP2D6) status and clinical outcomes in tamoxifen therapy. We performed a meta-analysis on data from 4,973 tamoxifen-treated patients (12 globally distributed sites). Using strict eligibility requirements (postmenopausal women with estrogen receptor-positive breast cancer, receiving 20 mg/day tamoxifen for 5 years, criterion 1); CYP2D6 poor metabolizer status was associated with poorer invasive disease-free survival (IDFS: hazard ratio = 1.25; 95% confidence interval = 1.06, 1.47; P = 0.009). However, CYP2D6 status was not statistically significant when tamoxifen…

Application of a new classification to a breast tumor series from a population-based cancer registry: demographic, clinical, and prognostic features …

2009

A new classification based on gene expression profiling or immunohistochemical (IHC) characteristics may replace current histopathological classifications and predict better clinical outcomes. We used IHC markers to classify incident cases ascertained by the Palermo Breast Cancer Registry (2002-2004) into four subtypes: luminal-A (ER+ or PgR+ and HER2/neu-); luminal-B (ER+ or PgR+, HER2/neu+); basal-like (ER-, PgR-, HER2/neu-); and HER2+/ER- (HER2/neu+, ER-, PgR-). We evaluated HER2/neu, ER and PgR in 1300/1985 (65%) cases. The most common IHC-subtype was luminal-A (68%), whereas luminal-B, basal-like, and HER2+/ER- accounted for 14%, 13%, and 5%, respectively. IHC-subtypes were not associa…

P021 Heat working environment and risk of breast, chronic lymphocytic leukaemia, colorectal, prostate, and stomach cancer in the MCC-spain case contr…

2016

Occupational exposure to heat can affect the absorption of carcinogenic chemicals into the body, and the metabolism of sexual hormones. We explored the association between occupational exposure to heat and breast, chronic lymphocytic leukaemia, colorectal, prostate, and stomach cancer in the MCC-Spain population based case-control study. Methods The analyses were based on 3047 controls, and 1499 breast, 1539 colorectal, 332 LLC, 1070 prostate, and 382 stomach cancer cases. Heat working environment from either natural or artificial sources was assessed with the MatEmEsp job-exposure matrix. Logistic regression models accounting for education, sex, geographic area, BMI (colorectal, prostate),…

Evaluation of the efficacy of low-level laser in improving the symptoms of burning mouth syndrome

2015

Background: Burning mouth syndrome (BMS) is common condition that affects menopause women, patients suffer from sever burning sensation. Up to now there is no definitive treatment for this disease. Present study was undertaken to evaluate the efficacy of low-level laser (LLL) in improving t he symptoms of burning mouth syndrome. Material and Methods: Twenty patients with BMS were enrolled in this study; they were divided in two groups randomly. In the laser group, in each patient, 10 areas on the oral mucosa were selected and underwent LLL irradiation at a wavelength of 630 nm, and a power of 30 mW for 10 seconds twice a week for 4 weeks. In the placebo group, silent/off laser therapy was c…

Long-term effects of oral and transdermal hormone replacement therapy on plasma homocysteine levels.

2003

Objective To compare the long-term effects of oral and transdermal hormone replacement therapy (HRT) on serum homocysteine levels in postmenopausal women. Design An open, prospective, controlled study. Seventy-five healthy postmenopausal women were recruited as eligible for the study. Fifty women seeking HRT were randomized to receive continuous 17beta-estradiol, either by oral (2 mg daily; n = 25) or transdermal (50 microg daily; n = 25) administration, plus 10 mg dydrogesterone daily for 14 days of each 28-day cycle. Twenty-five women unwilling to receive hormone treatment received only calcium supplementation, representing the control group. Fasting blood samples were analyzed at baselin…

Postmenopausal women with osteopenia and a healed wrist fracture have reduced physical function and quality of life compared to a matched, healthy co…

2013

Background Fractures lead to reduced physical function and quality of life (QOL), but little is known about postmenopausal women with osteopenia and a healed wrist fracture. The purpose was to evaluate physical function in terms of quadriceps strength, dynamic balance, physical capacity and QOL in postmenopausal women with osteopenia and a healed wrist fracture compared to a matched, healthy control group with no previous fracture. Methods Eighteen postmenopausal women with osteopenia (patients) (mean age 59.1 years, range 54 – 65) and a healed wrist fracture were matched to 18 healthy control subjects on age (mean age 58.5 years, range 51 – 65), height, weight and body mass index (BMI). We…

Stratosphere-troposphere exchange in the vicinity of a tropopause fold

2016

Abstract. Transport of air masses from the stratosphere to the troposphere along tropopause folds can lead to peaked ozone concentrations at ground level and hereby influence the long-term trend of tropospheric ozone. To improve the understanding of responsible processes and preferred regions of exchange, transient and reversible exchange processes in the vicinity of a tropopause fold are analysed on the basis of a case study. The global and regional atmospheric chemistry model system MECO(n), which couples the limited-area atmospheric chemistry and climate model COSMO-CLM/MESSy to the global model ECHAM5/MESSy for Atmospheric Chemistry (EMAC) is applied. Using similar process parametrisati…

Strong influence of lowermost stratospheric ozone on lower tropospheric background ozone changes over Europe

2007

[1] Using ozone measurements from two sounding sites and two high-altitude stations in Central Europe, we show evidence for a dominant influence of changes in lowermost stratospheric ozone on the variability and overall upward trend of background ozone in the lower troposphere (3000–3500 m asl) during the 1992–2004 period. Numerical simulations with a stratospheric chemistry transport model suggest that changes in lower stratospheric ozone were driven by dynamics rather than by changes in stratospheric chlorine loading. In addition, Lagrangian model simulations indicate that changes in downward transport of ozone from the stratosphere into the troposphere were dominated by changes in lowerm…
