Regional variations in Helicobacter pylori infection, gastric atrophy and gastric cancer risk: The ENIGMA study in Chile.
2020
International audience; Background: Regional variations in gastric cancer incidence are not explained by prevalence of Helicobacter pylori, the main cause of the disease, with several areas presenting high H. pylori prevalence but low gastric cancer incidence. The IARC worldwide H. pylori prevalence surveys (ENIGMA) aim at systematically describing age and sex-specific prevalence of H. pylori infection around the world and generating hypotheses to explain regional variations in gastric cancer risk.Methods: We selected age- and sex-stratified population samples in two areas with different gastric cancer incidence and mortality in Chile: Antofagasta (lower rate) and Valdivia (higher rate). Pa…
Sexual orientation predicts men’s preferences for sexually dimorphic face-shape characteristics: A replication study
2020
Many researchers have proposed that straight men prefer women’s faces displaying feminine shape characteristics at least partly because mating with such women will produce healthier offspring. Although a prediction of thisadaptation-for-mate-choicehypothesis is that straight men will show stronger preferences for feminized versus masculinized versions of women’s faces than will gay men, only one previous study has directly tested this prediction. Here we directly replicated that study by comparing 623 gay and 3163 straight men’s preferences for feminized versus masculinized versions of faces. Consistent with the adaptation-for-mate-choice hypothesis of straight men’s femininity preferences,…
Involuntary ambulatory triage during the COVID-19 pandemic – A neurosurgical perspective
2020
BackgroundThe coronavirus disease 2019 (COVID-19) pandemic poses an unprecedented challenge to health-care systems around the world. As approximately one-third of the world´s population is living under "lockdown" conditions, medical resources are being reallocated and hospital admissions are limited to emergencies. We examined the decision-making impact of these actions and their effects on access to hospital treatment in patients with neurosurgical conditions.MethodsThis retrospective cohort study analyzes hospital admissions of two major neurosurgical services in Germany during the nationwide lockdown period (March 16th to April 16th, 2020). Spinal or cranial conditions requiring immediat…
Sprint mechanical variables in elite athletes: Are force-velocity profiles sport specific or individual?
2019
Purpose The main aim of this investigation was to quantify differences in sprint mechanical variables across sports and within each sport. Secondary aims were to quantify sex differences and relationships among the variables. Methods In this cross-sectional study of elite athletes, 235 women (23 ± 5 y and 65 ± 7 kg) and 431 men (23 ± 4 y and 80 ± 12 kg) from 23 different sports (including 128 medalists from World Championships and/or Olympic Games) were tested in a 40-m sprint at the Norwegian Olympic Training Center between 1995 and 2018. These were pre-existing data from quarterly or semi-annual testing that the athletes performed for training purposes. Anthropometric and speed-time sprin…
The effect of an extra piece of fruit or vegetables at school on weight status in two generations - 14 years follow-up of the Fruit and Vegetables Ma…
2018
Background: The obesity epidemic presents a major public health challenge, and a poor diet quality has been identified as one of the most important contributing factors. Whereas a sufficient fruit and vegetable consumption has been associated with several positive health outcomes, the long-term effect on overweight and obesity is unclear. Thus, the aims of this study were to investigate if one year with free school fruit had any effect on weight status 14 years later, and if it affected the birth weight of the participants’ children. Methods: In 2001, 10 -12-year old Norwegian children, received one year of free school fruit in the intervention study “Fruits and Vegetables Make the Marks” (…
The skills related to the early reading acquisition in Spain and Peru
2018
This paper deals with the skills related to the early reading acquisition in two countries that share language. Traditionally on reading readiness research there is a great interest to find out what factors affect early reading ability, but differ from other academic skills that affect general school learnings. Furthermore, it is also known how the influence of pre-reading variables in two countries with the same language, affect the development of the reading. On the other hand, several studies have examined what skills are related to reading readiness (phonological awareness, alphabetic awareness, naming speed, linguistic skills, metalinguistic knowledge and basic cognitive processes), bu…
Prevalence of intimate partner violence against women in Sweden and Spain: A psychometric study of the 'Nordic paradox'.
2019
The high prevalence of intimate partner violence against women (IPVAW) in countries with high levels of gender equality has been defined as the "Nordic paradox". In this study we compared physical and sexual IPVAW prevalence data in two countries exemplifying the Nordic paradox: Sweden (N = 1483) and Spain (N = 1447). Data was drawn from the European Union Agency for Fundamental Rights Survey on violence against women. To ascertain whether differences between these two countries reflect true differences in IPVAW prevalence, and to rule out the possibility of measurement bias, we conducted a set of analyses to ensure measurement equivalence, a precondition for appropriate and valid cross-cul…
Prevalence of depressive symptoms among Italian medical students: The multicentre cross-sectional "PRIMES" study.
2020
Background Four percent of the world’s population suffers from depression, which is a major public health issue. Medical students are at risk, as their depressive symptoms (DS) prevalence is reported to be approximately 27% worldwide. Since few data on Italian medical students exist, this study aimed to estimate their DS prevalence and assess risk and protective factors. Methods The PRIMES was a multicentre cross-sectional study performed in 12 Italian medical schools. Questionnaires were self-reported and included 30 sociodemographic items and the Beck Depression Inventory-II (BDI-II). The primary outcome was the presence of DS (BDI-II score≥14). The main analyses were chi-squared tests an…
Relationship between perception of smile esthetics and orthodontic treatment in Spanish patients
2018
Este artículo se encuentra disponible en la página web de la revista en la siguiente URL: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0201102 One of the main objectives of orthodontic treatment is to achieve an esthetic smile. This study set out to analyze differences in the perception of smile esthetics among patients before and after receiving orthodontic treatment. 250 Spanish patients analyzed a single photograph in which, by means of computer software, midline diastema, black triangle, gingival margin of the left central incisor, and gingival (ªgummyº) smile were altered. Each patient analyzed these images before and after undergoing orthodontic treatment. Patient…
How work and family caregiving responsibilities interplay and affect registered dietitian nutritionists and their work: A national survey.
2021
Healthcare professionals provide paid care at work and potentially have caregiving responsibilities outside of work; work responsibilities in addition to child and/or elder care is considered double- or triple-duty care. Employees may experience conflict and/or enrichment as their work and family responsibilities interface. This study’s purpose is to explore the work and family interface of Registered Dietitian Nutritionists (RDNs), determine the prevalence of work-family conflict and enrichment, and identify characteristics associated with higher work-family conflict and enrichment scores. A survey instrument assessing caregiving responsibilities and work-family conflict and enrichment was…
