The Role of αvβ3 Integrin in Lamina Cribrosa Cell Mechanotransduction in Glaucoma.

Glaucoma, one of the leading causes of irreversible blindness, is a common progressive optic neuropathy characterised by visual field defects and structural changes to the optic nerve head (ONH). There is extracellular matrix (ECM) accumulation and fibrosis of the lamina cribrosa (LC) in the ONH, and consequently increased tissue stiffness of the LC connective tissue. Integrins are cell surface proteins that provide the key molecular link connecting cells to the ECM and serve as bidirectional sensors transmitting signals between cells and their environment to promote cell adhesion, proliferation, and remodelling of the ECM.

Swallowed topical steroid therapy for eosinophilic oesophagitis in children: practical, evidence-based guidance by the BSPGHAN Eosinophilic Oesophagitis Working Group.

Objective: To develop evidence-based guidance for topical steroid use in paediatric eosinophilic oesophagitis (pEoE) in the UK for both induction and maintenance treatment.

Methods: A systematic literature review using Cochrane guidance was carried out by the British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN) Eosinophilic Oesophagitis (EoE) Working Group (WG) and research leads to determine the evidence base for preparation, dosing and duration of use of swallowed topical steroid (STS) formulations in EoE. Seven themes relating to pEoE were reviewed by the WG, alongside the Cochrane review this formed the evidence base for consensus recommendations for pEoE in the UK.

Dissecting components of the gene cluster under iron limitation.

is a bacterium that is prevalent in the ceca of farmed poultry such as chickens. Consumption of ill-prepared poultry is thus the most common route by which infects the human gut to cause a typically self-limiting but severe gastrointestinal illness that can be fatal to very young, old, or immunocompromised people. The lack of a vaccine and an increasing resistance to current antibiotics highlight a need to better understand the mechanisms that make a successful human pathogen.

Dissecting components of the gene cluster in iron scavenging.

is a leading cause of bacterial gastroenteritis worldwide. Acute infection can be antecedent to highly debilitating long-term sequelae. Expression of iron acquisition systems is vital for to survive the low iron availability within the human gut.

Multiple proteins affecting the peptidoglycan structure and the degree of helical cell curvature.

is a Gram-negative helical bacterium. Its helical morphology, maintained by the peptidoglycan (PG) layer, plays a key role in its transmission in the environment, colonization, and pathogenic properties. The previously characterized PG hydrolases Pgp1 and Pgp2 are important for generating helical morphology, with deletion mutants being rod-shaped and showing alterations in their PG muropeptide profiles in comparison to the wild type.

Phosphomannomutase 2 (PMM2) variants leading to hyperinsulinism-polycystic kidney disease are associated with early-onset inflammatory bowel disease and gastric antral foveolar hyperplasia.

Phosphomannomutase 2 (PMM2) deficiency causes Congenital Disorder of Glycosylation (PMM2-CDG), but does not have a recognised association with Inflammatory Bowel Disease (IBD). A distinct clinical syndrome of hyperinsulinism and autosomal recessive polycystic kidney disease (HIPKD) arises in the context of a specific variant in the PMM2 promotor, either in homozygosity, or compound heterozygous with a deleterious PMM2 variant. Here, we describe the development of IBD in three patients with PMM2-HIPKD, with onset of IBD at 0, 6, and 10 years of age.

Safety and Efficacy of Split-Dose Thiopurine vs Low-Dose Thiopurine-Allopurinol Cotherapy in Pediatric Inflammatory Bowel Disease.

Introduction: Split-dose thiopurine and allopurinol-thiopurine cotherapy strategies have been suggested as rescue therapeutic options for children with inflammatory bowel disease (IBD) and impaired thiopurine metabolism. We compared the efficacy and safety of these regimens in patients who previously failed conventional thiopurine treatment.

Methods: Children with IBD treated with split-dose thiopurine or low-dose thiopurine-allopurinol cotherapy were retrospectively identified.

Abdominal US in Pediatric Inflammatory Multisystem Syndrome Associated with SARS-CoV-2 (PIMS-TS).

Background Children with pediatric inflammatory syndrome temporally associated with SARS-CoV-2 (PIMS-TS), also known as multisystem inflammatory syndrome in children, present with abdominal pain among other nonspecific symptoms. Although initial imaging features of PIMS-TS have been reported, the duration of sonographic features remains unknown. Purpose To describe the abdominal US features of PIMS-TS at initial presentation and follow-up.

Ambulance waiting and associated work flow improvement strategies: a pilot study to improve door-in-door-out time for thrombectomy patients in a primary stroke center.

Background: Rapid access to thrombectomy for patients with large vessel occlusion (LVO) acute ischemic stroke (AIS) is critical for improving outcome. A major challenge for the 'drip and ship' model is reducing the door-in-door-out time (DIDO). We propose a new protocol with the aim of reducing DIDO, without adversely affecting emergency service usage time.

Peptidoglycan binding by a pocket on the accessory NTF2-domain of Pgp2 directs helical cell shape of Campylobacter jejuni.

The helical morphology of Campylobacter jejuni, a bacterium involved in host gut colonization and pathogenesis in humans, is determined by the structure of the peptidoglycan (PG) layer. This structure is dictated by trimming of peptide stems by the LD-carboxypeptidase Pgp2 within the periplasm. The interaction interface between Pgp2 and PG to select sites for peptide trimming is unknown.

SARS-CoV-2 and the Gastrointestinal Tract in Children.

Coronavirus disease 2019 (COVID-19), caused by acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is predominantly a respiratory disease. However, its significant impact on the gastrointestinal (GI) system is now well-known. SARS-CoV-2 enters cells the angiotensin-converting enzyme-2 (ACE-2) receptor, which is abundantly expressed on lung cells, but also on enterocytes.

Unique inducible filamentous motility identified in pathogenic Bacillus cereus group species.

Active migration across semi-solid surfaces is important for bacterial success by facilitating colonization of unoccupied niches and is often associated with altered virulence and antibiotic resistance profiles. We isolated an atmospheric contaminant, subsequently identified as a new strain of Bacillus mobilis, which showed a unique, robust, rapid, and inducible filamentous surface motility. This flagella-independent migration was characterized by formation of elongated cells at the expanding edge and was induced when cells were inoculated onto lawns of metabolically inactive Campylobacter jejuni cells, autoclaved bacterial biomass, adsorbed milk, and adsorbed blood atop hard agar plates.

Cognitive impairment and medication adherence post-stroke: A five-year follow-up of the ASPIRE-S cohort.

Background: Control of vascular risk factors is essential for secondary stroke prevention. However, adherence to secondary prevention medications is often suboptimal, and may be affected by cognitive impairment. Few studies to date have examined associations between cognitive impairment and medication adherence post-stroke, and none have considered whether adherence to secondary prevention medications might affect subsequent cognitive function.

[Pulmonary hypertension associated with the human immunodeficiency virus in children: treatment with sildenafil. A case report].

Pulmonary hypertension associated with human immunodeficiency virus infection is an extremely rare disease in pediatrics; it requires a high clinical suspicion to reach a diagnosis. Its appearance poses an unfavorable prognostic, but early diagnosis and specific treatment can improve outcomes. We report the clinical case of a fifteen-year-old patient diagnosed with human immunodeficiency virus infection of vertical transmission, without antiretroviral treatment, with cough and progressive exertional dyspnea, associated with signs of right heart failure in which severe pulmonary hypertension was diagnosed.

Retrospective review of effectiveness and safety of intravenous ferric carboxymaltose given to children with iron deficiency anaemia in one UK tertiary centre.

Unlabelled: In the paediatric population, ferric carboxymaltose (FCM) is only licenced for use in children older than 14 years, and the data in younger children remains scarce. We retrospectively reviewed data of all paediatric patients less than 14 years old who had received FCM infusion from August 2011 to June 2015 at the John Radcliffe Hospital (Oxford University Hospitals), UK. The patient demographics, significant medical history, FCM dose, and blood investigations (pre-FCM and post-FCM) were reviewed.

Interarm blood pressure difference in a post-stroke population.

An increased interarm systolic blood pressure (SBP) difference of ≥10 mm Hg is associated with increased cardiovascular risk and a difference of ≥15 mm Hg with increased cerebrovascular risk. The stroke population presents a high-risk group for future cardiovascular and cerebrovascular events and therefore estimation of interarm SBP difference as a predictive tool may assist with further secondary stroke prevention. The aim of the study was to determine the prevalence of interarm SBP and diastolic blood pressure difference in a post-stroke population.
