Salivary Melatonin Rhythm and Prostate Cancer: CAPLIFE Study

Purpose: To analyze the association between salivary melatonin rhythm and prostate cancer (PCa). Materials and Methods: A total of 40 PCa cases and 41 controls from CAPLIFE study were analyzed to determine the salivary melatonin rhythm through 6 saliva samples. Amplitude (maximum melatonin peak) was categorized as low or high using the cut-off point median…

The Role of European Schools and University Departments of Public Health in the 2020 COVID-19 Response, European Region, 2020

Objective: The main objective was to examine, how European Schools of Public Health (SPHs) responded to the COVID-19 pandemic through 2020, across the main activity domains of the SPHs. Methods: A cross-sectional survey based on an online questionnaire concerning the anti-COVID-19 activities from 1st March to 31st October 2020 of the 117 members of the…

Milk intake and incident stroke and coronary heart disease in populations of European descent: A Mendelian Randomization study

Higher milk intake has been associated with a lower stroke risk, but not with risk of coronary heart disease (CHD). Residual confounding or reverse causation cannot be excluded. Therefore, we estimated the causal association of milk consumption with stroke and CHD risk through instrumental variable (IV) and gene-outcome analyses. IV analysis included 29,328 participants (4,611…

The economic burden of anxiety and depression on the working age population with diabetes in Spain

Diabetes mellitus (DM) is a complex, chronic, multifactorial, and costly health problem representing 8% of total public health expenditures in Spain. The objective of this study was to analyse the prevalence and costs of Anxiety (AX) and Depression (DP) in the Spanish working population with DM. Data were obtained from the National Health Survey of…

Trends in gender of authors of original research in oncology among major medical journals: a retrospective bibliometric study

Objective We evaluated the temporal trend in gender ratios of first and last authors in the field of oncological research published in major general medical and oncology journals and examined the gender pattern in coauthorship. Design We conducted a retrospective study in PubMed using the R package RISmed. We retrieved original research articles published in…

Food biodiversity and total and cause-specific mortality in 9 European countries: An analysis of a prospective cohort study

Background Food biodiversity, encompassing the variety of plants, animals, and other organisms consumed as food and drink, has intrinsic potential to underpin diverse, nutritious diets and improve Earth system resilience. Dietary species richness (DSR), which is recommended as a crosscutting measure of food biodiversity, has been positively associated with the micronutrient adequacy of diets in…

High-risk subtypes of chronic lyphocytic leukemia are detectable as early as 16 years prior to diagnosis

Chronic lymphocytic leukemia (CLL) is preceded by monoclonal B-cell lymphocytosis (MBL), a CLL precursor state with a prevalence of up to 12% in aged individuals. However, the duration of MBL and the mechanisms of its evolution to CLL remain largely unknown. In this study, we sequenced the B-cell receptor immunoglobulin heavy chain (BcR IGH) gene…

Multilevel Zero-One Inflated Beta Regression Model for the Analysis of the Relationship between Exogenous Health Variables and Technical Efficiency in the Spanish National Health System Hospitals

Background: This article proposes a methodological innovation in health economics for the second stage analysis of technical efficiency in hospitals. It investigates the relationship between the installed capacity in regions and hospitals and their ownership structure. Methods: A multilevel zero-one inflated beta regression model is employed to model pure technical efficiency more adequately than other…

Public Perceptions of the Role of Lifestyle Factors in Cancer Development: Results from the Spanish Onco-Barometer 2020

The European Code against Cancer recommends not to smoke, to avoid alcohol consumption, to eat a healthy diet, and maintain a healthy weight to prevent cancer. To what extent is the public aware of the influence of these lifestyle factors on cancer development? The goal of the current study was to describe the perceived influence…

A New Pipeline for the Normalization and Pooling of Metabolomics Data

Pooling metabolomics data across studies is often desirable to increase the statistical power of the analysis. However, this can raise methodological challenges as several preanalytical and analytical factors could introduce differences in measured concentrations and variability between datasets. Specifically, different studies may use variable sample types (e.g., serum versus plasma) collected, treated, and stored according…
