RESUMO
BACKGROUND: Breast cancer (BC) is the second most frequent cancer in women and the second most common cancer worldwide. Lifestyle factors, like body weight, physical activity and diet, may be accompanying with higher BC risk. AIM: The assessment of macronutrients dietary intake; protein, fat, carbohydrates and their components of amino, fatty acids, and central obesity/adiposity among pre- and postmenopausal Egyptian women with benign and malignant breast tumors. METHODS: The current case control study included 222 women: 85 control, 54 benign and 83 breast cancer patients. Clinical, anthropocentric and biomedical examinations were performed. Dietary history and health attitude were done. RESULTS: The anthropometric parameters including waist circumference (WC) and the body mass index (BMI) of the benign and the women with malignant breast lesions showed the highest values when compared to the control (35.45 ± 15.58 km2 and 101.24 ± 15.01 cm, 31.39 ± 6.77 km2 and 98.85 ± 13.53 cm and 27.51 ± 7.10 km2 and 84.33 ± 13.78 cm). The biochemical parameters revealed high concentration of the total cholesterol (TC) (192.83 ± 41.54 mg/dl), low density lipoprotein-cholesterol (LDL-C) (117.88 ± 35.18 mg/dl) and the median insulin level 13.8 (10.2-24.1) µu/ml in the malignant patients with high significant difference compared to the control. The malignant patients had the highest daily caloric intake (795.84 ± 519.95 K calories) proteins (65.39 ± 28.77 g), total fats (69.09 ± 32.15 g) and carbohydrates (196.70 ± 85.35 g), when compared to the control. Data also revealed the high daily consumption of the different types of the fatty acids with high linoleic/linoleinic ratio among the malignant group (14.284 ± 6.25). Branched chain amino acids (BGAAs), sulphur amino acids (SAAs), conditional amino acids (CAAs) and aromatic amino acids (AAAs) proved to be the highest in this group. Correlation coefficient between the risk factors revealed either positive or negative weak correlation except that between serum LDL-C concentration and the amino acids (isoleucine, valine cysteine, tryptophan and tyrosine) and negative association with the protective polyunsaturated fatty acids. CONCLUSION: Participants with breast cancer had the greatest levels of body fatness and unhealthy feeding habits relative to their high calorie, protein, carbohydrate, and fat intake.

Cigarette smoking appears to have adverse effects of male reproductivity. The interplay between zinc and cadmium presumably plays a role in mediating toxic effects of smoking. This work was conducted to study serum and seminal plasma zinc and cadmium level in smokers compared to non-smokers. Seventy males were included: 35 smokers (group I) (smoking Ë20 cigarettes/day with mild smoking index <400) and 35 age-matched non-smokers (group II). Semen analysis was performed according to the WHO laboratory manual 2010. Atomic absorption spectrophotometer was used to detect zinc and cadmium amounts in both blood plasma and semen of any groups. Smoker group showed significantly lower sperm density, motility (P=0.001), and sperm viability (P=0.002) and higher abnormally formed sperms. Seminal zinc level was significantly lower in smokers (P=0.038).There was significant negative correlation between seminal zinc and smoking index and significant positive correlation between seminal zinc levels and sperm motility (P=0.008) and viability percentage (P=0.001). Seminal cadmium level was significantly higher in smoker (P=0.022). Significant positive correlation between seminal cadmium and both age and smoking index (P=0.003) and significant negative correlation between seminal cadmium and sperm density (P=0.005), motility (P=0.047), and viability (P=0.039). Seminal zinc level was negatively correlated to seminal cadmium level (P=0.020). Smoking has deleterious effects on semen quality hence fertility through several toxicants and chemicals. Reduced zinc levels and elevated cadmium levels were evident in smokers which have significant role in the adverse effects on the semen parameters.
