Objective: The objective of this study is to further highlight the differences between different ABO blood groups and Rhesus types with health biomarkers.

Methods: In total 150 active healthy blood donors participated in our study comprising of 80 males from 19-61 years and 70 females aged from 21 to 64. Participants carrying blood group A were 55 individuals, blood group B 32, blood group O 51, and blood group AB 12, RHD+ 132, and RHD- 18.

A cross-sectional study for assessing perceived symptoms, depression and quality of life in advanced lung cancer patients.

Purpose: The purpose of the present study was to assess the perceived symptoms, depression and quality of life (QoL) in advanced lung cancer patients undergoing chemotherapy.

Methods: The study was cross sectional and was conducted in the oncology department of General Hospital "George Papanikolaou", Thessaloniki, Greece. The sample was convenient and consisted of 76 advanced lung cancer patients.

Adequate vitamin D supplementation does not ameliorate bone loss following long limb-biliopancreatic diversion in morbidly obese women.

Objectives: The objective of this study is to investigate the effect of adequate vitamin D supplementation on bone mineral density (BMD) following long limb-biliopancreatic diversion (LL-BPD), a malabsorptive bariatric operation.

Background: Marked weight loss following bariatric surgery is associated with significant decrease in BMD, attributed to the weight loss and to nutritional, mineral, and vitamin D deficiencies resulting in secondary hyperparathyroidism.

Methods: Two groups, of 35 and 37 healthy, obese (BMI, 50.

The incidence of nausea and vomiting in cancer patients in Greek clinical practice: A longitudinal study.

Aim Of The Study: To assess nausea and vomiting in cancer patients during two cycles of chemotherapy, and the impact on their quality of life.

Material And Methods: A longitudinal study was conducted in an oncology department of a large general public hospital in Northern Greece. The sample consisted of 200 cancer patients.

Berkson's paradox and weighted distributions: An application to Alzheimer's disease.

One reason for observing in practice a false positive or negative correlation between two random variables, which are either not correlated or correlated with a different direction, is the overrepresentation in the sample of individuals satisfying specific properties. In 1946, Berkson first illustrated the presence of a false correlation due to this last reason, which is known as Berkson's paradox and is one of the most famous paradox in probability and statistics. In this paper, the concept of weighted distributions is utilized to describe Berskon's paradox.

A comparison of statistical and machine-learning techniques in evaluating the association between dietary patterns and 10-year cardiometabolic risk (2002-2012): the ATTICA study.

Statistical methods are usually applied in examining diet-disease associations, whereas factor analysis is commonly used for dietary pattern recognition. Recently, machine learning (ML) has been also proposed as an alternative technique in health classification. In this work, the predictive accuracy of statistical v.

Repeatability of dietary patterns extracted through multivariate statistical methods: a literature review in methodological issues.

In the last few years, the need for processing large amount of data in nutrition science was dramatically arose. This created the need to apply, primarily, advanced analytical research methods that could enable researchers to handle the large amount of information. Dietary pattern analysis is a commonly used approach to enable and incorporate this phenomenon in nutrition research.

Validity of dietary patterns derived in nutrition surveys using a priori and a posteriori multivariate statistical methods.

Aim: To evaluate the validity of dietary patterns derived using both a priori and a posteriori methods.

Method: Five hundred individuals (46 ± 16 years, 40% males) completed a valid 76-food item food frequency questionnaire and a 3-day dairy. The MedDietScore was used to a priori assess the adherence to the Mediterranean diet, while principal components and cluster analysis were used as the a posteriori methods.

Test-retest reliability of the Kuopio instrument for fathers (KIF): a questionnaire to assess fathers' feelings, experiences and preparation for their wife/partner's delivery.

Objective: to assess the test-retest reliability of the Greek version of the Kuopio Instrument for Fathers (KIF) questionnaire that explores fathers' feelings, experiences and preparation for their wife/partner's delivery.

Design: the KIF questionnaire was translated into Greek, back translated and adapted to the Greek population. After a pilot test, it was administered to a sample of fathers.

Different effects of sensitization to mites and pollens on asthma symptoms and spirometric indices in children: a population-based cohort study.

Background: We have previously shown that long-term exposure of children to a highly polluted urban compared with a rural environment is associated with subclinical airway narrowing and increased prevalence of atopy.

Objective: To test the hypothesis that sensitization to indoor perennial, compared with seasonal, aeroallergens has distinct effects on asthma symptoms and/or spirometric indices.

Methods: We evaluated the respiratory health of 478 and 342 children aged 8 to 10 years living in an urban and a rural area, respectively, during a period of 8 years.

Increased sensitization in urban vs. rural environment--rural protection or an urban living effect?

In a population-based longitudinal cohort study, we tested the hypothesis that children growing up in a high-traffic polluted urban area (UA) in the Athens' basin have higher prevalence of allergies and sensitization when compared with those growing up in a Greek provincial rural area (RA). We recruited 478 and 342 children aged 8-10 living in the UA and the RA, respectively. Respiratory health was assessed by a parent-completed questionnaire in three phases: 1995-96 (phase 1), 1999-2000 (phase 2), 2003-04 (phase 3) and skin-prick testing to common indoor and outdoor aeroallergens was performed at phases 1 and 2.

Different effects of urban and rural environments in the respiratory status of Greek schoolchildren.

We hypothesized that asthma symptoms and lung function of schoolchildren living in Athens urban area are adversely affected as compared to others living in a rural environment, over a period of 8 years. We recruited 478 and 342 children aged 8-10 years living within a short radius around the urban and rural area monitoring stations, respectively. Respiratory health was assessed by a parent-completed questionnaire in three phases: 1995-1996 (phase-1), 1999-2000 (phase-2), 2003-2004 (phase-3) and by spirometry in phases-1 and 2.
