CIPER, Faculdade de Motricidade Humana, SpertLab, Universidade de Lisboa, Portugal.

Background: Relative age effect (RAE) has been found to be particularly pronounced between 13 and 15 years of age in male football. However, the extent to which the phenomenon varies within a country demands a more comprehensive approach.

Purpose: To examine the effects of (north; centre-north; centre-south; south; islands), (top-ranked; middle-ranked; bottom-ranked) and (goalkeeper; defender; midfielder; forward) on the birthdate distribution (Q1: January-March; Q2: April-June; Q3: July-September; Q4: October-December) of U14 Portuguese players selected for the national inter-association tournament Lopes da Silva.

The rapid diffusion of the jennerian method was founded in simplicity to practice, in its apparent effectiveness in combating smallpox and its epidemiological opportunity, as it appeared at the time of greatest recrudescence of the disease. The initial impulse for it's propagation, which originated a recognized movement to protect population health, was not without controversy. At the same time that defenders of the vaccine were added, opposite opinions appeared that used diverse critics to discredit it. Read More

The disease of Sigmund Freud: oral cancer or cocaine-induced lesion?

Eur Arch Otorhinolaryngol 2019 Jan 17;276(1):263-265. Epub 2018 Oct 17.

Department of Otorhinolaryngology, Vita-Salute San Raffaele University, San Raffaele Scientific Institute, Via Olgettina 60, 20132, Milan, Italy.

Purpose: Sigmund Freud, the father of modern psychoanalysis, suffered from what was considered to be a malignant tumour spreading from the back of his palate.

as a potential defender against swimmer's itch in European recreational water bodies-experimental study.

PeerJ 2018 25;6:e5045. Epub 2018 Jun 25.

Department of Invertebrate Zoology, Faculty of Biology and Environment Protection, Nicolaus Copernicus University of Torun, Toruń, Poland.

Swimmer's itch is a re-emerging human disease caused by bird schistosome cercariae, which can infect bathing or working people in water bodies. Even if cercariae fail after penetrating the human skin, they can cause dangerous symptoms in atypical mammal hosts. One of the natural methods to reduce the presence of cercariae in the environment could lie in the introduction of non-host snail species to the ecosystem, which is known as the "dilution" or "decoy" effect.

Mol Autism 2018 19;9:29. Epub 2018 Apr 19.

Ethics, Collections, and History of Medicine, Medical University of Vienna, Währinger Straße 25, 1090 Vienna, Austria.

Background: Hans Asperger (1906-1980) first designated a group of children with distinct psychological characteristics as 'autistic psychopaths' in 1938, several years before Leo Kanner's famous 1943 paper on autism. In 1944, Asperger published a comprehensive study on the topic (submitted to Vienna University in 1942 as his postdoctoral thesis), which would only find international acknowledgement in the 1980s. From then on, the eponym 'Asperger's syndrome' increasingly gained currency in recognition of his outstanding contribution to the conceptualization of the condition. Read More

University of Florida, USA.

Using the social-ecological and social cognitive theories as integrated guiding frameworks, the present study examined whether moral disengagement and defender self-efficacy at the individual level, and moral disengagement, quality of teacher-student relationships and quality of student-student relationships at the classroom level were associated with passive bystanding and defending in bullying situations.
