Objective: To determine survival and neurodevelopmental outcomes in the Hypotension in Preterm (HIP) trial.

Design: Prospective follow-up of infants enrolled in randomised controlled trial.

Participants: 58 infants born before 28 weeks of gestation with low mean arterial blood pressure.

Clinical Epidemiology, Etiology, and Outcomes of Upper Gastrointestinal Bleeding at a Tertiary Center in Bahrain: A Retrospective Study.

Background Upper gastrointestinal bleeding (UGIB) is one of the most common major medical emergencies. This study sought to determine the epidemiology, clinical characteristics, and outcomes of UGIB in the largest major tertiary care center in Bahrain, compared to regional and international cohorts. Methods We conducted a retrospective cohort study of all patients diagnosed with UGIB between April 2021 and April 2022 in Salmaniya Medical Complex, Bahrain's largest tertiary-level public hospital.

Subhepatic Appendicitis With Appendicular Diverticulitis: A Rare Combination for Acute Abdomen.

Subhepatic appendicitis is an unusual presentation of acute appendicitis (AA). Similarly, another uncommon condition that resembles AA is appendiceal diverticulitis (AD), which is a rare form of vermiform appendix pathology. It is exceedingly uncommon for the two to occur simultaneously.

Understanding the role of biomolecular coronas in human exposure to nanomaterials.

Nanomaterials (NMs) are increasingly used in medical treatments, electronics, and food additives. However, nanosafety-the possible adverse effects of NMs on human health-is an area of active research. This review provides an overview of the influence of biomolecular coronas on NM transformation following various exposure routes.

Protocols for isolation and characterization of nanoparticle biomolecular corona complexes.

Engineered nanoparticles (NPs) pose a broad spectrum of interesting properties that make them useful for many applications. However, continuous exposure to NPs requires the need to deeply understand the outcomes when these NPs interact with different biological environments. After exposure within (to) these environments, the pristine surfaces of NPs strongly interact with the molecules from the surrounding medium, including metabolites, lipids, glycan, and proteins, forming the so-called protein corona (PC).

"This is it…this is our normal" - the voices of family members and first responders experiencing duty-related trauma in Ireland.

Background: Compared to other occupational groups, first responders (FR) experience worse mental health outcomes due to duty-related trauma and occupational stressors. Despite their best efforts, they bring this stress home to friends and family. Consequently, FR and their supporters suffer from increased psychosocial difficulties and experience stigma and other barriers to help-seeking.

Development of a fast and simple method for the isolation of superparamagnetic iron oxide nanoparticles protein corona from protein-rich matrices.

The adsorption of proteins onto the surface of nanoparticle (NP) leads to the formation of the so-called "protein corona" as consisting both loosely and tightly bound proteins. It is well established that the biological identity of NPs that may be acquired after exposure to a biological matrix is mostly provided by the components of the hard corona as the pristine surface is generally less accessible for binding. For that reason, the isolation and the characterisation of the NP-corona complexes and identification of the associated biomolecules can help in understanding its biological behaviour.

Probing the glycans accessibility in the nanoparticle biomolecular corona.

Hypothesis: Following blood administration, the pristine surface of nanoparticles (NPs) associates with biomolecules from the surrounding environment forming the so-called "biomolecular corona". It is well accepted that the biomolecular corona dramatically affects the NP fate in the biological medium while the pristine surface is no longer available for binding. Recent studies have shown that the glycans associated with the proteins forming the corona have a role in the NP interaction with macrophages, but the glycan identities remain unknown.

In depth characterisation of the biomolecular coronas of polymer coated inorganic nanoparticles with differential centrifugal sedimentation.

Advances in nanofabrication methods have enabled the tailoring of new strategies towards the controlled production of nanoparticles with attractive applications in healthcare. In many cases, their characterisation remains a big challenge, particularly for small-sized functional nanoparticles of 5 nm diameter or smaller, where current particle sizing techniques struggle to provide the required sensitivity and accuracy. There is a clear need for the development of new reliable characterisation approaches for the physico-chemical characterisation of nanoparticles with significant accuracy, particularly for the analysis of the particles in the presence of complex biological fluids.

Unilateral dorsiflexor strengthening with mirror therapy to improve motor function after stroke: A pilot randomized study.

Background: Independently, cross-education, the performance improvement of the untrained limb following unilateral training, and mirror therapy have shown to improve lower limb functioning poststroke. Mirror therapy has shown to augment the cross-education effect in healthy populations. However, this concept has not yet been explored in a clinical setting.

The European Board of Interventional Radiology Examination: A Cross-Sectional Web-Based Survey.

Introduction: The Cardiovascular and Interventional Radiology Society of Europe established the European Board of Interventional Radiology (EBIR) as an international examination in Interventional Radiology (IR), in 2010. The main objective of this study was to examine candidates' variables which could influence examination success. The secondary objective was to evaluate candidate feedback.
