Open access and data sharing in cancer stem cells research.

Objective: Understanding and targeting cancer stem cells (CSC) are areas of active research in oncology and further dissemination of scientific results is urgently needed to accelerate the comprehension of their involvement in tumor heterogeneity, resistance to conventional therapies and metastasis. In the context of open science, open access and data sharing, the aim of this study is to assess the current practices of cancer researchers in terms of publications and dissemination of research data.

Method: A bibliometric study was conducted based on a bibliographic search using the Web of Science, and CSC articles with at least one Spanish affiliation were retrieved.

Risk of cancer development associated with disease-modifying therapies for multiple sclerosis: study protocol for a systematic review and meta-analysis of randomised and non-randomised studies.

Background: The association between cancer and multiple sclerosis has long been investigated. Several studies and reviews have examined the risk of cancer among patients with multiple sclerosis treated with disease-modifying therapies (DMTs) but with conflicting results. This study will aim to investigate the association between DMTs for multiple sclerosis and subsequent cancer risk using research synthesis methods.

The inclusion of the gender perspective in oncology research with Spanish participation.

The gender perspective is important for a better diagnosis and treatment of diseases, especially in the field of oncology. This study aimed to analyse the gender approach in scientific articles in the field of oncology by studying the gender composition of the authorship of papers and the gender inclusion in the research carried out. A bibliographic search of articles and reviews signed by at least one Spanish institution published between 2010 and 2019 was carried out using the Science Citation Index Expanded database in the Oncology category.

Study Design And Setting: We evaluated a random sample of health economic evaluations indexed in MEDLINE during 2019. We included articles written in English reporting an incremental cost-effectiveness ratio in terms of costs per life years gained, quality-adjusted life years, and/or disability-adjusted life years.

The 100 most cited articles in peri-implant diseases. A bibliometric study of the web of science.

Background: The purpose of the study was to analyze the 100 most-cited articles on peri-implantitis pathology in the Web of Science database.

Material And Methods: The articles were selected from all categories of the Web of Science, to consider all variations and synonyms of peri-implant disease. Articles were reviewed for typographical, transcription, and indexing errors.

Evaluating the online impact of reporting guidelines for randomised trial reports and protocols: a cross-sectional web-based data analysis of CONSORT and SPIRIT initiatives.

Unlabelled: Reporting guidelines are tools to help improve the transparency, completeness, and clarity of published articles in health research. Specifically, the CONSORT (Consolidated Standards of Reporting Trials) and SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) statements provide evidence-based guidance on what to include in randomised trial articles and protocols to guarantee the efficacy of interventions. These guidelines are subsequently described and discussed in journal articles and used to produce checklists.

Lumbar paravertebral tumor in a newborn: congenital lipomatous nevus.

Introduction: Skin lesions in close proximity to the lumbosacral region should be assessed in newborns, since they may be the first sign of hidden spinal dysraphism.

Clinical Case: We present the case of a newborn without significant prenatal history. On the first day of life, a 1 cm diameter nodular lesion was found at the lumbar level of the right paravertebral region, with a vascular stain surrounding the base of the lesion.

Laser-based refractive surgery techniques to treat myopia in adults. An overview of systematic reviews and meta-analyses.

Systematic reviews (SRs) and meta-analyses (MAs) are of great importance for basing clinical decisions. However, misleading interpretations may result when informed decisions rest on biased review papers with methodological issues. To evaluate which treatment is optimal, an overview was made of SRs and MAs to establish the quality and certainty of meta-evidence published on the efficacy of laser-based refractive surgery techniques for treating myopia in adults.

Mortality in Persons With Autism Spectrum Disorder or Attention-Deficit/Hyperactivity Disorder: A Systematic Review and Meta-analysis.

Importance: Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are childhood-onset disorders that may persist into adulthood. Several studies have suggested that they may be associated with an increased risk of mortality; however, the results are inconsistent.

Objective: To assess the risk of mortality among persons with ASD or ADHD and their first-degree relatives.

[COVID-19 and Smoking: A Systematic Review and Meta-Analysis of the Evidence].

Objective: The aim of this study was to determine if tobacco use in patients with Covid-19 is associated with a negative disease course and adverse outcome, and if smoking, current and past, is associated with a greater possibility of developing COVID-19.

Material And Methods: A systematic review (SR) and meta-analysis (MA) of previously published works were performed. The search strategy included all known descriptors for Covid-19 and tobacco and was conducted in different databases.
