Selenium dietary intake and survival among CRC patients.

Despite advances in prevention and treatment, colorectal cancer remains the second most common cause of cancer death. To date, little is known about the role of prediagnostic selenium intake in colorectal cancer survival. The purpose of the study was to verify whether selenium intake in habitual diet before diagnosis is associated with survival in colorectal cancer patients.

Calcium intake may explain the reduction of colorectal cancer odds by dietary selenium - a case-control study in Poland.

Background: Colorectal cancer (CRC) has been placed among top three cancer sites in high income countries. Although there are several inconsistencies across studies it is widely accepted that diet contributes to approximately 70% of CRC. Several dietary factors have been investigated; however, the knowledge about the role of trace elements and their interplay with other dietary factors in CRC odds is limited.

Whole-cell pertussis vaccine (DTwP) has no influence on allergic diseases and atopic sensitization in children.

Introduction: Vaccine opponents indicate that the infant's immune system is inadequately developed to handle multiple vaccines which may overwhelm the immune system, leading to allergic diseases.

Aim: To verify the association between the vaccine antigen overload derived from DTwP and the development of atopic sensitization and allergic diseases.

Material And Methods: Data from an earlier established birth cohort in Krakow, followed up to the 6 year of life were used.

Experience with Saccharomyces boulardii Probiotic in Oncohaematological Patients.

Very few reports have been published to date on the bloodstream infections caused by Saccharomyces spp. in oncohaematological patients, and there are no guidelines on the use of this probiotic microorganism in this population. We describe the use of probiotic preparation containing Saccharomyces boulardii in a large group of oncohaematological patients.

The effectiveness of rotavirus vaccine in preventing acute gastroenteritis during rotavirus seasons among Polish children.

Introduction: Rotavirus is the main etiological cause of intestinal infections in children. Voluntary rotavirus vaccines were included in the Polish vaccination schedule in 2007. The aim of this study was to assess the effectiveness of a completed rotavirus vaccination course in preventing acute gastroenteritis in Polish infants during their first five years of life.

Sensitivity of passive diarrhea surveillance in infants up to the second year of life in Małopolskie voivodeship.

Introduction: In EU countries and also in Poland, the surveillance of infectious acute gastro-enteritis is a mandatory system based on cases notification (suspected and confirm) conducted by physicians in hospitals and ambulatory care.

Study Objective: The assessment of surveillance sensitivity on acute diarrhea in children up to 2nd year of life in Małopolskie voivodeship from 2009 to 2012.

Material And Methods: The data about 720 infants surveyed respectively from birth up to 2nd year of life were used in this study.

Usefulness of maternal assessment of children development based on reported age of achieved milestones.

Study Objective: The aim of the study was to examine the usefulness of maternal recall of selected developmental milestones by testing their correlations with the Bayley Scales of Infant Development (BSID-II).

Material And Methods: Prospective cohort study. The cohort recruited prenatally, included 387 children.

Stability of the mental and motor Bayley Scales of Infant Development (2nd ed.) in infants over first three years of life.

Unlabelled: Despite the Bayley Scales of Infant Development second edition (BSID-II) are wide used both clinically and in research settings, only a few published studies have been examined their stability over time.

Aim Of Study: The aim of this study was to examine the stability of mental and motor BSID-II scores over the first three years of life.

Material And Methods: All children included in this study were a sample followed up in a study on the susceptibility of the fetus and child to environmental factors.

Does dietary calcium interact with dietary fiber against colorectal cancer? A case-control study in Central Europe.

Background: An unfavorable trend of increasing rates of colorectal cancer has been observed across modern societies. In general, dietary factors are understood to be responsible for up to 70% of the disease's incidence, though there are still many inconsistencies regarding the impact of specific dietary items. Among the dietary minerals, calcium intake may play a crucial role in the prevention.

Measles, mumps and rubella (MMR) vaccination has no effect on cognitive development in children - the results of the Polish prospective cohort study.

Objectives: The aim of the study was to examine the hypothesis that MMR exposure has a negative influence on cognitive development in children. Furthermore, MMR was compared to single measles vaccine to determine the potential difference of these vaccines safety regarding children's cognitive development.

Methods: The prospective birth cohort study with sample consisted of 369 infants born in Krakow.

The frequency and risk factors of allergy and asthma in children with autism--case-control study.

Introduction: The evolution of autistic disorders in children depends on many factors, like concomitance of the other diseases, which can escalate the autistic symptoms. One of those groups are allergic diseases, which have one of the highest prevalence rates in children.

Objectives: The aim of this analysis was to determine the frequency of asthma and allergy in children with autism in comparison to controls and the risk factors of allergic diseases and asthma in both groups.

[The influence of rotavirus vaccinations on the risk of gastrointestinal infections in children. Methods and preliminary results].

Unlabelled: The gastrointestinal infection in infants are the significant health and epidemiological issue. The voluntary rotavirus vaccines was included to Polish vaccination schedule in 2007.

Aim Of The Study: Aim of the study was the assessment of rotaviruses vaccines effectiveness in prevention of rotavirus gastrointestinal infections requiring hospitalization and the influence or these vaccinations on the risk of gastrointestinal outpatient infections.

Neonatal exposure to Thimerosal from vaccines and child development in the first 3 years of life.

Background: Despite the common use of Thimerosal as a preservative in childhood vaccines since the 1930s, there are not many studies on ethylmercury toxicokinetics and toxicodynamics in infants. The knowledge of ethylmercury's potential adverse effects is derived mostly from parallel methylmercury research or from animal and theoretical models.

Aim Of The Study: This study was designed to examine the relationship between neonatal exposure to Thimerosal-containing vaccine (TCV) and child development.

[Lack of association between thimerosal-containing vaccines and autism].

In Poland, administered childhood vaccines still contain thimerosal as a preservative. Despite the access to mercury free formulas, the most of children are still vaccinated by thimerosal-containing vaccines (TCV) owing to economical reasons. That circumstances caused the rising discussion on potential harmful influence of TCVs on children health.

[The parents opinion on the risk factors of autism in their children].

The mothers' opinions about the reasons of their children autism have been collected during case-control study on risk factors of that disease. The relationship between different opinions and mothers' characteristics have been analyzed. The categories of autism reasons mentioned by mothers have been related to the current knowledge about the risk factors of disease.
