Results: A total of 13,629 articles were retrieved.

Ulcerative Colitis: A Critical Approach to the Global Research Output Employing Density-equalizing Mapping and Scientometric Methods.

Background And Aims: Despite decades of effort, numerous aspects on ulcerative colitis (UC) remain unknown and require further investigation. Scientists experience numerous challenges to survey >40,000 items that have been published on UC since 1900, to evaluate their scientific impact or to identify collaborative networks publishing the most relevant work. Hence, no current, detailed and comprehensive knowledge regarding the worldwide research architecture of UC has been established until now.

A world map of evidence-based medicine: Density equalizing mapping of the Cochrane database of systematic reviews.

Systematic reviews represent the core and backbone of evidence-based medicine (EBM) strategies in all fields of medicine. In order to depict a first global sketch of the international efforts in the Cochrane database systematic reviews (CDSR), we analyzed the systematic reviews of the Cochrane database. Our global maps of systematic reviewing offer intriguing structural insights into the world of EBM strategies.

Health behaviors in dance teachers and their use of psychoactive substances.

Background: Dance teachers (DTs) give lessons on various professional and amateur genres. Up to the present, little has been known on health-related behavior regarding the consumption of substances such as inhalant and synthetic substances, cocaine, cannabis/marijuana (c/m), anabolic steroids and naturally occurring hallucinogens in dance teachers.

Relevance: To analyze the consumption of these substances as well as to determine influencing variables due to their role model function (educational level, prevalence of injuries, BMI and income).

Anterior Thalamic Excitation and Feedforward Inhibition of Presubicular Neurons Projecting to Medial Entorhinal Cortex.

The presubiculum contains head direction cells that are crucial for spatial orientation. Here, we examined the connectivity and strengths of thalamic inputs to presubicular layer 3 neurons projecting to the medial entorhinal cortex in the mouse. We recorded pairs of projection neurons and interneurons while optogenetically stimulating afferent fibers from the anterior thalamic nuclei.

After publication of the original article [1], the authors reported two errors which needed to be corrected.

Crohn's Disease: A Critical Approach to Publication Procedures and Citation Behavior of the Global Research Network.

Background And Goals: Crohn's disease (CD) is an inflammatory bowel disease, which can lead to abdominal pain, weight loss, fatigue, severe diarrhea, and malnutrition. Despite enormous efforts and progress in diagnosis and therapy, there are still many aspects of uncertainty leading to an increasing scientific interest in this topic. As it is challenging to survey all articles regarding CD and to measure their scientific importance, this study uses reliable scientometric tools to evaluate the global research output on CD related to quantitative and qualitative aspects and in chronological and geographical context.

Glioblastoma research: US and international networking achievements.

Being the most aggressive type of brain tumor, glioblastoma is estimated to be diagnosed in about 12,400 new cases in 2017. The diagnosis is dramatic to patients and relatives and leaves open many unanswered questions for them. One is the big question why there is no cure as in other tumors.

Particulate matter emissions of different brands of mentholated cigarettes.

Unlabelled: Inhaling particulate matter (PM) in environmental tobacco smoke (ETS) endangers the health of nonsmokers. Menthol, an additive in cigarettes, attenuates respiratory irritation of tobacco smoke. It reduces perceptibility of smoke and therefore passive smokers may inhale ETS unnoticed.

World-wide research architecture of vitamin D research: density-equalizing mapping studies and socio-economic analysis.

The uterine fibroid/myoma tumour: analysis of the global research architecture using density-equalizing mapping.

Uterine fibroids can severely impact a woman's quality of life, result in significant morbidity and are a leading indication for hysterectomy. Many aspects of the disease remain largely obscure. Despite these knowledge gaps, no detailed maps of the global fibroid research architecture have yet been generated.

Ectopic pregnancy: exploration of its global research architecture using density-equalising mapping and socioeconomic benchmarks.

Objective: About 2% of all pregnancies are complicated by the implantation of the zygote outside the uterine cavity and termed ectopic pregnancy. Whereas a multitude of guidelines exists and related research is constantly growing, no thorough assessment of the global research architecture has been performed yet. Hence, we aim to assess the associated scientific activities in relation to geographical and chronological developments, existing research networks and socioeconomic parameters.
