Classification of pediatric soft and bone sarcomas using DNA methylation-based profiling.

Pediatric sarcomas present heterogeneous morphology, genetics and clinical behavior posing a challenge for an accurate diagnosis. DNA methylation is an epigenetic modification that coordinates chromatin structure and regulates gene expression, determining cell type and function. DNA methylation-based tumor profiling classifier for sarcomas (known as sarcoma classifier) from the German Cancer Research Center (Deutsches Krebsforschungszentrum) was applied to 122 pediatric sarcomas referred to a reference pediatric oncology hospital.

The Glycan Ectodomain of SARS-CoV-2 Spike Protein Modulates Cytokine Production and Expression of CD206 Mannose Receptor in PBMC Cultures of Pre-COVID-19 Healthy Subjects.

The ability of recombinant, SARS-CoV-2 Spike (S) protein to modulate the production of two COVID-19 relevant, pro-inflammatory cytokines (IL-6 and IFN-γ) in PBMC cultures of healthy, pre-COVID-19 subjects was investigated. We observed that cytokine production was largely and diversely modulated by the S protein depending on antigen or mitogen stimulation, as well as on the protein source, insect (S-in) or human (S-hu) cells. While both proteins co-stimulated cytokine production by polyclonally CD3-activated T cells, PBMC activation by the mitogenic lectin Concanavalin A (Con A) was up-modulated by S-hu protein and down-modulated by S-in protein.

Applying the Participatory Slow Design Approach to a mHealth Application for Family Caregivers in Pediatric Ear, Nose, and Throat Surgery.

Pediatric ear, nose, and throat (ENT) surgery is very common, and its outcomes may improve with family education. In this regard, mobile health (mHealth) applications (apps), which are on the rise due to digital transformation, can be beneficial in healthcare. This study outlines the user-centered design and development of a mHealth app (version 5.

Mycobacterium tuberculosis antigen 85B modifies BCG-induced antituberculosis immunity and favors pathogen survival.

Tuberculosis is one of the deadliest infectious diseases worldwide. Mycobacterium tuberculosis has developed strategies not only to evade host immunity but also to manipulate it for its survival. We investigated whether Mycobacterium tuberculosis exploited the immunogenicity of Ag85B, one of its major secretory proteins, to redirect host antituberculosis immunity to its advantage.

Identification of two anti- antibodies associated with the survival of patients with candidemia.

Candidemia (bloodstream invasion by species) is a major fungal disease in humans. Despite the recent progress in diagnosis and treatment, therapeutic options are limited and under threat of antimicrobial resistance. The disease mortality remains high (around 40%).

11p15 Epimutations in Pediatric Embryonic Tumors: Insights from a Methylome Analysis.

Embryonic tumors share few recurrent mutations, suggesting that other mechanisms, such as aberrant DNA methylation, play a prominent role in their development. The loss of imprinting (LOI) at the chromosome region 11p15 is the germline alteration behind Beckwith-Wiedemann syndrome that results in an increased risk of developing several embryonic tumors. This study analyzed the methylome, using EPIC Beadchip arrays from 99 sporadic embryonic tumors.

Study protocol for a randomised controlled trial to determine the effectiveness of a mHealth application as a family supportive tool in paediatric otolaryngology perioperative process (TONAPP).

Background: Otorhinolaryngology (ORL) surgery is common in children, but hospitalisation, surgery, and home care after discharge are stressful experiences for young patients and their family caregivers. Findings from literature highlight a lack of time in hospitals to support ORL surgery children and their caregivers through the perioperative process, along with the risks of caregivers' autonomous web or social media resources investigation. Therefore, this study aims to evaluate the effectiveness of a mobile health application with content to support ORL patients and their caregivers in the perioperative period to reduce caregiver anxiety and child distress compared to standard care.

'How is our job affecting us?' Neonatal Intensive Care Unit healthcare providers and their pregnancy: A descriptive qualitative study.

Aim: The aim of this study was to understand the Neonatal Intensive Care Unit (NICU) healthcare providers' (HCPs) experiences and needs during their own past, present and desired pregnancies. It has been reported that HCPs' personal and professional lives are mutually interconnected. Given the NICU HCPs' knowledge of the risks and potential adverse outcomes of newborns admitted to the NICU, their pregnancy experience may be more challenging than that of the general population.

Somatic Copy Number Alteration in Circulating Tumor DNA for Monitoring of Pediatric Patients with Cancer.

Pediatric tumors share few recurrent mutations and are instead characterized by copy number alterations (CNAs). The cell-free DNA (cfDNA) is a prominent source for the detection of cancer-specific biomarkers in plasma. We profiled CNAs in the tumor tissues for further evaluation of alterations in 1q, and 17p in the circulating tumor DNA (ctDNA) in the peripheral blood at diagnosis and follow-up using digital PCR.

Molecular In-Depth on the Epidemiological Expansion of SARS-CoV-2 XBB.1.5.

Since the beginning of the pandemic, the generation of new variants periodically recurs. The XBB.1.

A multi-method quasi-experimental study to assess compassion satisfaction/fatigue in nurses, midwives and allied health professionals receiving a narrative medicine intervention.

Aims: To: (1) measure the impact of a narrative medicine intervention on compassion fatigue and compassion satisfaction of nurses, midwives and allied health professionals; (2) explore participants' working experiences and (3) their impressions of the intervention.

Design: Multi-methods, quasi-experimental before-after intervention design.

Methods: The intervention consisted of 20 narrative medicine sessions (60 h).

What do hospital-based health professionals need and expect from an mHealth app to support the first 1000 days of life? Results from a cross sectional study.

Background: Several attempts have been made to introduce mHealth solutions to support maternal, newborn, and child health (MNCH). However, most of the available apps do not meet the needs of end-users, underscoring the urgency of involving them in the co-design of telehealth interventions.

Objective: With this in mind, we investigated the needs and expectations of hospital-based health professionals (i.

Genome-based comparison between the recombinant SARS-CoV-2 XBB and its parental lineages.

Recombination is the main contributor to RNA virus evolution, and SARS-CoV-2 during the pandemic produced several recombinants. The most recent SARS-CoV-2 recombinant is the lineage labeled XBB, also known as Gryphon, which arose from BJ.1 and BM.

Exploring the Needs and Expectations of Expectant and New Parents for an mHealth Application to Support the First 1000 Days of Life: Steps toward a Co-Design Approach.

To improve maternal and child health, it is essential to adhere to health-promoting and preventive measures. However, reliable information as well as effective tools are not easy to identify in this field. Our cross-sectional study investigated the needs and expectations of expectant and new mothers and fathers as potential primary users of a hypothetical application supporting the first 1000 days of life.

CARE 1000: randomized controlled trial for the evaluation of the effectiveness of a mHealth app for supporting the first 1000 days of life.

Background: Recent developments in eHealth and mobile health (mHealth), as well as the introduction of information and communication technology innovations in clinical practice, such as telemedicine, telemonitoring, and remote examinations, are already changing the current scenario and will continue to generate innovations in the coming decades. The widespread use of mobile devices, with an estimated nearly 30 billion devices and more than 325,000 apps worldwide, will provide various opportunities for people to take control of their own health. Already in 2017, most of the apps available were focused on pregnancy support, more than any other medical field.
