Physical activity, early first delivery and residence as parameters for breast cancer prevention: an observational study.

Purpose: To determine the impact of physical activity, obesity, history of maternity, residence and socioeconomic status on the prevention of breast cancer (BC).

Methods: We established a questionnaire in order to record several potential parameters associated with BC in women aged between 30 and 60 years. The parameters evaluated in the present study were physical activity (years and days per week), obesity, age of menarche, age of first delivery, breast feeding, family history of BC, vegetarian diet, residence and socioeconomic status.

Hypothesis: Is heroin a 'barrier' against cancer? A retrospective analysis of heroin-addicted individuals untreated for opioid dependence between 2001-2010.

Purpose: The findings of previous studies attracted our interest in searching and defining the percentage of deaths from cancer in 'heroin regular addicts' i.e. those who had never stopped taking the drug since they started.

The Amount of Phosphorus in the Blood of Heroin Abusers Compared to that of Healthy Subjects.

Background: The aim of the current retrospective study was to assess any difference in terms of serum phosphate (P) between heroin addicts and healthy subjects.

Methods: Between 2011 and 2012, under the authority of the Greek Organization Against Drugs (OKANA), 30 regular heroin addicts, 22 males and 8 females (Group A) participated at the study. Between 2010 and 2011, 30 healthy individuals, 22 males and 8 females (Group B), presented on an outpatient basis for either fatigue or common flu symptoms without fever at the 424 Military Hospital of Thessaloniki.

Pheromones: a new ergogenic aid in sport?

Nowadays, antidoping laboratories are improving detection methods to confirm the use of forbidden substances. These tests are based both on direct identification of new substances or their metabolites and on indirect evaluation of changes in gene, protein, or metabolite patterns (genomics, proteomics, or metabolomics). The World Anti-Doping Agency (WADA) officially monitors anabolic steroids, hormones, growth factors, β-agonists, hormone and metabolic modulators, masking agents, street drugs, manipulation of blood and blood components, chemical and physical manipulation, gene doping, stimulants, narcotics, glucocorticosteroids, and β-blockers.

Is there any potential clinical impact of serum phosphorus and magnesium in patients with lung cancer at first diagnosis? A multi-institutional study.

Background: The aim of the study was to determine whether the expression of baseline phosphorus (P) and magnesium (Mg) levels were prognostic in terms of stage and overall survival (OS) in newly diagnosed non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) patients.

Materials And Methods: Retrospectively, 130 patients were selected at the time of diagnosis oflung cancer (100 with NSCLC and 30 with SCLC), before the initialization of any chemo-radiotherapy. The median age was 67 (range 29-92).
