On behalf of the Editorial Board, welcome to the new "Italian Journal of Pediatrics," the official journal of the ISP/SIP (Italian Society of Pediatrics/Società Italiana di Pediatria), now publishing on BioMed Central's open access publishing platform. The move to BioMed Central will benefit authors by having thei…

The front cover artwork is provided by Dr. Alberto Fernández-Alarcón. The image symbolizes the interactions of a molecule, via its orbitals, with an electromagnetic field, to produce the spectroscopic signals observed in NMR. Read the full text of the Concept at 10.1002/cphc.202200667.

INTRODUCTION: One of the main tasks in information retrieval is the development of Boolean search strategies for systematic searches in bibliographic databases. This includes the identification of free-text terms and controlled vocabulary. IQWiG has previously implemented its objective approach for search strategy deve…

The Internet has made finding evidence for clinical practice fairly easy. Many different types of databases that can be searched for relevant key terms are available for free or for subscription. Bibliographic or library databases contain books, book chapters, reports, citations, abstracts, and either the full text of…

A semi-automatic procedure that extracts metadata from MEDLINE was used to develop a search tool that facilitates online location and (free) access to full-text electronic documents from the Proceedings of the American Medical Informatics Association (AMIA) Annual Symposia (1997-2003). Log file analysis for six months…

The rapid growth of smartphone ownership and broadband access has created new opportunities to reach smokers with cessation information and support using digital technologies. These technologies can both complement and be integrated with traditional support modalities such as telephone quitlines and 1-on-1 clinical ces…

We propose an approach to predicting implicit gene-disease associations based on the inference network, whereby genes and diseases are represented as nodes and are connected via two types of intermediate nodes: gene functions and phenotypes. To estimate the probabilities involved in the model, two learning schemes are…

We report two rare cases of patients presenting with unusual symptoms, which led to the diagnosis of a germ cell tumor. Metastatic germ cell tumor of testis involving the gastrointestinal tract and causing the occult gastrointestinal bleeding is described in the first case. The second patient is reported to have limbic…

Haemophiliac pseudotumors are usually observed in the diaphysis of long bones. Pseudotumors due to psoas muscle hematoma are rare and surgical management is difficult. Surgical treatment of these lesions is usually associated with high morbidity and mortality rate. Here, we present a case with iliopsoas haemophiliac ps…

Broad absorption signatures from alkali metals, such as the sodium (Na I) and potassium (K I) resonance doublets, have long been predicted in the optical atmospheric spectra of cloud-free irradiated gas giant exoplanets. However, observations have revealed only the narrow cores of these features rather than the full pr…

OBJECTIVE: Text messaging interventions are effective. Despite high utilization of smartphones, few studies evaluate text messaging for cessation in middle-/lower-income countries. Initiating tobacco treatment in hospitals is an effective but underutilized approach for reaching smokers. We evaluated a hybrid phone coun…

BACKGROUND: Confirmed oncogenic microbes contribute significantly to cancer burden. Identifying and confirming novel microbial oncogenicity could yield strategies and tools that will reduce disease burdens. However, relevant evidence may be dispersed across a vast biomedical literature that is infeasible for humans to…

During the flight of birds, it is often possible to notice that some of the primaries and covert feathers on the upper side of the wing pop-up under critical flight conditions, such as the landing approach or when stalking their prey (see Fig. 1) . It is often conjectured that the feathers pop up plays an aerodyna…

In this paper, by taking full consideration of distributed delay, demographics and contact heterogeneity of the individuals, we present a detailed analytical study of the Susceptible-Infected-Removed (SIR) epidemic model on complex population networks. The basic reproduction number [Formula: see text] of the model is d…

This article provides a brief history of the development of the MEDLINE database and its huge impact within the UK, from its inception to the present time. The origins of MEDLINE can be traced back to a collection of books in the US Surgeon General's Office during the American Civil War and John Shaw Billings' decision…

In this article, we show the results of a quantitative and qualitative analysis of open citations on a popular and highly cited retracted paper: "Ileal-lymphoid-nodular hyperplasia, non-specific colitis and pervasive developmental disorder in children" by Wakefield et al, published in 1998. The main purpose of our stud…

Delay line oscillators based on photonic components, offer the potential for realization of phase noise levels up to 3 orders of magnitude lower than achievable by conventional microwave sources. Fibreoptic-based delay lines can realize the large delay required for low phase noise systems whilst simultaneously achievin…

Biomarker-guided oncology trials frequently prioritize surrogate endpoints to enable efficient development in molecularly defined populations, often before mature overall survival (OS) data are available. We conducted a PRISMA 2020-guided systematic review of prospective interventional biomarker-guided oncology trials…

Online medical text is full of references to medical entities (MEs), which are valuable in many applications, including medical knowledge-based (KB) construction, decision support systems, and the treatment of diseases. However, the diverse and ambiguous nature of the surface forms gives rise to a great difficulty for…

The OSTMED.DR® database provides access to both citation and full-text osteopathic literature, including the Journal of the American Osteopathic Association. Currently, it is a free database searchable using basic and advanced search features.
