An open-label feasibility trial of transdermal cannabidiol for hand osteoarthritis.

Hand osteoarthritis (OA) is an irreversible degenerative condition causing chronic pain and impaired functionality. Existing treatment options are often inadequate. Cannabidiol (CBD) has demonstrated analgesic and anti-inflammatory effects in preclinical models of arthritis.

Type I interferon blockade with anifrolumab in patients with systemic lupus erythematosus modulates key immunopathological pathways in a gene expression and proteomic analysis of two phase 3 trials.

Introduction: Anifrolumab is a type I interferon (IFN) receptor 1 (IFNAR1) blocking antibody approved for treating patients with systemic lupus erythematosus (SLE). Here, we investigated the immunomodulatory mechanisms of anifrolumab using longitudinal transcriptomic and proteomic analyses of the 52-week, randomised, phase 3 TULIP-1 and TULIP-2 trials.

Methods: Patients with moderate to severe SLE were enrolled in TULIP-1 and TULIP-2 and received intravenous anifrolumab or placebo alongside standard therapy.

Machine Learning Predicts Oxaliplatin Benefit in Early Colon Cancer.

Purpose: A combination of fluorouracil, leucovorin, and oxaliplatin (FOLFOX) is the standard for adjuvant therapy of resected early-stage colon cancer (CC). Oxaliplatin leads to lasting and disabling neurotoxicity. Reserving the regimen for patients who benefit from oxaliplatin would maximize efficacy and minimize unnecessary adverse side effects.

Innate immune dysregulation in multisystem inflammatory syndrome in children (MIS-C).

MIS-C is a systemic inflammation disorder with poorly characterised immunopathological mechanisms. We compared changes in the systemic immune response in children with MIS-C (n = 12, 5-13 years) to healthy controls (n = 14, 5-15 years). Analysis was done in whole blood treated with LPS.

Multi-omic interactions in the gut of children at the onset of islet autoimmunity.

Background: The gastrointestinal ecosystem is a highly complex environment with a profound influence on human health. Inflammation in the gut, linked to an altered gut microbiome, has been associated with the development of multiple human conditions including type 1 diabetes (T1D). Viruses infecting the gastrointestinal tract, especially enteroviruses, are also thought to play an important role in T1D pathogenesis possibly via overlapping mechanisms.

Multisystem inflammatory syndrome in the context of paediatric COVID-19 infection in the Republic of Ireland April 2020 to April 2021.

Aim: Our aim was to describe the epidemiology of multisystem inflammatory syndrome in children (MIS-C) in the Republic of Ireland, in the context of all cases of COVID-19 in children, during the first year of the SARS-CoV-2 pandemic.

Methods: Cases of MIS-C were identified by prospective surveillance in Irish hospitals from April 2020 to April 2021. Paediatric COVID-19 cases and outbreaks in schools or childcare facilities were notified to and routinely investigated by Public Health.

Trainee Knowledge and Perceptions of Less Than Full Time Training.

Background Less than full-time (LTFT) training in Ireland is still unusual. Our aim was to identify perceived barriers to LTFT training amongst paediatric trainees and make recommendations to improve knowledge, uptake, and experience of LTFT training. Methods An email questionnaire was disseminated to RCPI paediatric trainees to assess current awareness of and perceptions of barriers to LTFT training.

Innovations in Therapy Development for Rare Diseases Through the Rare Disease Cures Accelerator-Data and Analytics Platform.

Rare diseases impact the lives of an estimated 350 million people worldwide, and yet about 90% of rare diseases remain without an approved treatment. New technologies have become available, such as gene and oligonucleotide therapies, that offer great promise in treating rare diseases. However, progress toward the development of therapies to treat these diseases is hampered by a limited understanding of the course of each rare disease, how changes in disease progression occur and can be effectively measured over time, and challenges in designing and running clinical trials in diseases where the natural history is poorly characterized.

Emergence of Congenital Chagas Disease in Ireland.

Chagas disease (CD) is an under-diagnosed tropical disease that is increasingly being observed outside of Latin America. We describe the first 2 infants with congenital Chagas Disease (cCD) in Ireland. Clinicians in nonendemic countries need to be aware of the potential for cCD due to the migration of women from countries of high prevalence.

Metaproteomic sample preparation methods bias the recovery of host and microbial proteins according to taxa and cellular compartment.

Faecal proteomics studies have focussed on identification of microbial proteins, however; stool represents a valuable resource to interrogate the host interactions with the microbiota without the need for invasive intestinal biopsies. As the widely used enrichment method (differential centrifugation, DC) enriches for microbial proteins, we compared two other methods for enrichment of host proteins, termed 'host enriched' (HE) and ALL (all proteins). The HE and ALL protocols identified 1.

An acetate-yielding diet imprints an immune and anti-microbial programme against enteric infection.

Objectives: During gastrointestinal infection, dysbiosis can result in decreased production of microbially derived short-chain fatty acids (SCFAs). In response to the presence of intestinal pathogens, we examined whether an engineered acetate- or butyrate-releasing diet can rectify the deficiency of SCFAs and lead to the resolution of enteric infection.

Methods: We tested whether a high acetate- or butyrate-producing diet (HAMSA or HAMSB, respectively) condition infection in mice and assess its impact on host-microbiota interactions.

Validation of the NSABP/NRG Oncology 8-Gene Trastuzumab-benefit Signature in Alliance/NCCTG N9831.

Our objective was to validate the NSABP 8-gene trastuzumab-benefit signature, developed and initially validated in NRG Oncology/NSABP B-31 in Alliance/NCCTG N9831. The B-31 and N9831 trials demonstrated the benefit of adding trastuzumab to chemotherapy in the adjuvant setting for HER2+ breast cancer patients. NSABP investigators utilized gene expression profiles of N9831 patients (N = 892) to blindly assign patients to large-, moderate-, or no-trastuzumab benefit groups and then NCCTG investigators assessed the degree of trastuzumab benefit using Cox models adjusted for age, nodes, estrogen receptor/progesterone receptor status, tumor size, and grade.

Neratinib-Plus-Cetuximab in Quadruple-WT () Metastatic Colorectal Cancer Resistant to Cetuximab or Panitumumab: NSABP FC-7, A Phase Ib Study.

Purpose: In metastatic colorectal cancer (mCRC), () gene amplification is implicated in anti-EGFR therapy resistance. We sought to determine the recommended phase II dose (RP2D) and efficacy of neratinib, a pan-ERBB kinase inhibitor, combined with cetuximab, in patients with progressive disease (PD) on anti-EGFR treatment.

Patients And Methods: Twenty-one patients with quadruple-wild-type, refractory mCRC enrolled in this 3+3 phase Ib study.

The clinical presentation, treatment and outcome of serologically confirmed paediatric Lyme disease in the Republic of Ireland over a 5-year period: a retrospective cohort study.

Lyme disease (LD) is the most common tick-borne illness in Europe. Population-based studies in European children are few. This study aimed to assess the incidence, clinical presentation, treatment and outcome of serologically confirmed paediatric LD in the Republic of Ireland over a 5-year period.

National Guidelines on the Provision of Outpatient Parenteral Antimicrobial Therapy (OPAT).

Aim Outpatient parenteral antimicrobial therapy (OPAT) is an option in patients who require parenteral antimicrobial administration and are clinically well enough for hospital discharge. This is an update of the Irish National OPAT guidelines which were last reviewed in 2011. Methods The guideline was devised through a collaborative process with the national OPAT Working Group and a review of the literature.

Effects of an integrative approach to bipolar disorders combining psychoeducation, mindfulness-based cognitive therapy and functional remediation: Study protocol for a randomized controlled trial.

Introduction: Bipolar disorder is related to a high level of personal, familial, social and economic burden. There is a need for feasible adjunctive psychological interventions easy to implement in clinical practice in order to enhance aspects that medication alone cannot achieve. This study aims to evaluate the impact of a 12-session adjunctive integrative program designed for patients with bipolar disorder.

Establishing Patient Registries for Rare Diseases: Rationale and Challenges.

Globally, an estimated 350 million people are affected by a rare disease diagnosis. Knowledge limitations persist for the majority of rare conditions due to systemic and structural challenges in healthcare and research. Disease-specific patient populations are often small and geographically dispersed; funding support for research is restricted; and diagnostic delays are common due to disease complexities, limited medical training for practitioners, and evolving foundational knowledge related to disease characterization.

Correction to: NSABP FB-7: a phase II randomized neoadjuvant trial with paclitaxel + trastuzumab and/or neratinib followed by chemotherapy and postoperative trastuzumab in HER2+ breast cancer.

After the publication of this work [1] the authors have reported that in Table 3 The letter "T" in columns 5 and 7 should not be there.

NSABP FB-7: a phase II randomized neoadjuvant trial with paclitaxel + trastuzumab and/or neratinib followed by chemotherapy and postoperative trastuzumab in HER2 breast cancer.

Purpose: The primary aim of NSABP FB-7 was to determine the pathologic complete response (pCR) rate in locally advanced HER2-positive (HER2) breast cancer patients treated with neoadjuvant trastuzumab or neratinib or the combination and weekly paclitaxel followed by standard doxorubicin plus cyclophosphamide. The secondary aims include biomarker analyses.

Experimental Design: pCR was tested for association with treatment, gene expression, and a single nucleotide polymorphism (SNP) in the Fc fragment of the IgG receptor IIIa-158V/F (FCGR3A).
