Abstract Background This study aimed to investigate overall and sex-specific excess all-cause mortality since the inception of COVID-19 pandemic until August 2020 among 22 countries. Methods Countries reported weekly or monthly from January 2015 end June 2020. Weekly deaths were for Excess was calculated by comparing (observed deaths) against a baseline obtained 2015–2019 data same week month using two methods: (i) difference in observed rates between average (ii) expected deaths. Results...

Abstract Background The COVID-19 pandemic and the widespread adoption of virus control measures have inevitably disrupted efforts to address lifestyle risk factors for non-communicable diseases (NCD). This study aimed explore effects lockdown on all medicine pillars, namely diet, physical activity, sleep, stress, social support use risky substances. Methods was a cross-sectional convenient sample adults who resided in Cyprus during Spring 2020 lockdown. Participants completed an anonymous...

Diet has long been suspected to impact on breast cancer risk. In this study we evaluated whether the degree of adherence a Mediterranean diet pattern modifies risk amongst Greek-Cypriot women. Subjects included 935 cases and 817 controls, all participating in MASTOS case-control Cyprus. The was approved by Cyprus National Bioethics Committee. Information dietary intakes collected using an interviewer administered 32-item Food Frequency Questionnaire. demographic, anthropometric, lifestyle,...

Abstract Background To understand the impact of COVID-19 pandemic on mortality, this study investigates overall, sex- and age-specific excess all-cause mortality in 20 countries, during 2020. Methods Total, weekly for 2015–2020 was collected from national vital statistics databases. Excess 2020 calculated by comparing observed against expected estimated historical data (2015–2019) accounting seasonality, long- short-term trends. Crude age-standardized rates were analysed total sex-specific...

ABSTRACT Healthy midlife cognitive function (CF) reduces the risk of later decline. Emerging evidence suggests that chrono‐nutrition may be associated with CF. This cross‐sectional cohort study aimed to examine associations between behaviours and CF in adults aged 45–65 years living Cyprus. Chrono‐nutrition, including misalignments actual preferred eating times, Mediterranean diet (MD) adherence, sleep physical activity were assessed using validated questionnaires. Computerised...

Although there is some evidence suggesting that olive oil could reduce breast cancer (BC) risk, the epidemiological data are still relatively limited, not entirely consistent and mainly based on case-control studies. Therefore, we prospectively assessed association between BC risk in postmenopausal women from Mediterranean cohorts within European Prospective Investigation into Cancer Nutrition. The analysis included 62,284 recruited Spain, Italy Greece who had complete dietary (collected...

Huntington’s disease is a rare neurodegenerative caused by cytosine–adenine–guanine (CAG) trinucleotide expansion in the Huntingtin (HTT) gene. Although (HD) well studied, pathophysiological mechanisms, genes and metabolites involved HD remain poorly understood. Systems bioinformatics can reveal synergistic relationships among different omics levels enables integration of biological data. It allows for overall understanding pathways, HD. The purpose this study was to identify differentially...
