    Group B Streptococcus (GBS) vaccines, designed to be given to pregnant women, are in clinical trials. There is an opportunity to conduct preparatory research now to understand the drivers of and barriers to GBS vaccine acceptance. This will enable targeted interventions so that delays in vaccine uptake might be avoided. A multicenter, mixed-methodology, cross-sectional study evaluated the acceptability of a hypothetical GBS vaccine among pregnant women in two countries with differing health systems. Pregnant women in Philadelphia, US, and Dublin, Ireland, completed an electronic survey and a Discrete Choice Experiment. Five hundred and two women were included in the final analysis. Fifty-three percent of US and 30% of Irish participants reported both awareness and understanding of GBS. The median likelihood score for vaccine receipt (measured on a 10-point scale) was 9 (US: 9 (IQR 7-10), IRL: 9 (IQR 6-10)). Among the US participants, identifying as Black or African American was associated with a lower likelihood of vaccine receipt. Possession of a college degree was associated with increased likelihood of vaccine receipt. Perceived infant benefit was the most important driver of GBS vaccine acceptance. Safety concerns about a novel vaccine was the most prominent barrier identified. Good GBS vaccine uptake is achievable through strong messaging that highlights vaccine safety and the potential infant benefits. Preparation for vaccine implementation should include efforts to increase awareness among pregnant women about GBS infection and a continued focus on improving acceptability of currently recommended maternal vaccines, particularly in population subgroups with low uptake of maternal immunizations.

  • Case Report: Acquired collagenoma on the dorsum of the foot.

    O'Donohoe, Patrick; Theopold, Christoph; McMenamin, Mairin (2022-03-10)
    Collagenoma is a rare benign skin lesion classified as a hamartomatous proliferation of normal collagen fibres and varying amounts of elastic fibres. They most frequently occur on the arms or trunk and may present as solitary or multiple lesions, as part of a syndrome (such as Cowden Syndrome, Tuberous Sclerosis, or MEN1) or sporadic and of varying sizes. Herein, we report on a case of large acquired collagenomas found in an unusual location on the dorsum of both feet.
  • The impact of the COVID-19 pandemic on the provision of endovascular thrombectomy for stroke: an Irish perspective.

    Background: The COVID-19 pandemic produced unprecedented challenges to healthcare systems. These challenges were amplified in the setting of endovascular thrombectomy (EVT) for large vessel occlusion strokes given the time-sensitive nature of the procedure. Aims: To assess the impact of the COVID-19 pandemic on service provision at the primary endovascular stroke centre in Ireland. Methods: A retrospective review of the National Thrombectomy Service database was performed. All patients undergoing EVT from 1 January to 31 December inclusive of 2019 to 2021 were included. Patient demographics, functional outcomes and endovascular treatment time metrics were recorded. Results: Data from 2019, 2020 and 2021 were extracted. Three hundred seven thrombectomies were performed in 2019 and 2020; this number increased to 327 in 2021. Median time from arrival to groin puncture for thrombectomy was 64 min in 2019, increasing to 65 min in 2020. In 2021, this decreased to 52 min. Median time taken from groin puncture to first perfusion remained stable from 2019 to 2021 years at 20 min. Total duration of emergency thrombectomies reduced from 32 min in 2019 to 27 min in 2020. This increased to 29 min in 2021. Conclusions: Despite the myriad of challenges presented by the pandemic, service provision at the primary Irish ESC, and the referring hospitals, has proven to be robust. Procedural time metrics were maintained whilst the expected reduction in number of EVTs performed did not materialise, there actually being a significant increase in number of EVTs performed in the pandemic's second year.

    Mitochondrial methionyl-tRNA formyltransferase (MTFMT) is required for the initiation of translation in mitochondria. Pathogenic variants in MTFMT have been described in association with clinical presentations with Leigh syndrome, as well with as multisystem involvement (particularly cardiac and ocular involvement). There is a spectrum of severity, but many reported presentations have been milder with a better prognosis than other pathogenic variants associated with Leigh syndrome. We describe the case of a 9-year-old boy homozygous for a pathogenic MTFMT variant (c.626C > T/p.Ser209Leu) who presented with hypertensive crisis on a background of hyperphagia and visual impairment. His clinical course was complicated by supraventricular tachycardia and severe autonomic instability, requiring intensive care unit admission. He also developed seizures, neurogenic bladder and bowel and had a markedly abnormal eye examination with bilateral optic atrophy. Magnetic resonance image brain showed abnormal high T2/fluid-attenuated inversion recovery signal within the dorsal brainstem and in the right globus pallidus with some reduced diffusivity. Despite recovery from the acute neurological and cardiac manifestations, he has ongoing deficits in his gross motor skills and continues to have hyperphagia with rapid weight gain (approx. 20 kg in 2 years). Ophthalmic findings are persistent. This case expands the phenotype associated with MTFMT disease.

  • The Role of a Seven-Day Physiotherapy Service in Reducing Length of Stay and Improving Cost-Effectiveness in Arthroplasty Surgery.

    Cashman, James; Staunton, Peter; Grant-Freemantle, Marc; Pomeroy, Eoghan (2023-01-18)
    Background Length of hospital stay post hip and knee arthroplasty is influenced by several factors, including gender, home circumstances and underlying diagnosis. Due to increasing demand for hip and knee arthroplasty, elective units, operating within already stressed healthcare systems, must identify methods of increasing efficiency and capacity. We sought to establish whether the lack of a seven-day inpatient physiotherapy service resulted in an increased hospital length of stay post primary hip and knee arthroplasty. Methods One hundred consecutive joint replacements (50 total hip replacements and 50 total knee replacements (TKRs)), performed in our institution from January to February 2020, were assessed. The length of stay for the cohort was analysed, and delays to discharge were identified. T-test was used to analyse the difference in length of stay based on the day of the week the surgery was performed. Results The mean length of stay for all primary hip and knee arthroplasties was 3.42 (standard deviation (SD): 1.62) days. Hip and knee arthroplasties performed on a Thursday or Friday had a significantly higher average length of stay than those performed on Monday, Tuesday or Wednesday (3.89 versus 3.02, p=0.006). We calculated that operating a six-day versus seven-day physiotherapy service in our unit cost 318 bed days per year equating to €986,535. Conclusion Length of stay post total hip and knee arthroplasty in our unit is significantly affected by the day of the week that surgery is performed. Elective orthopaedic units should consider all means of maximising efficiency and lowering costs given the future challenges in service provision.
  • FK506-Binding Protein like (FKBPL) Has an Important Role in Heart Failure with Preserved Ejection Fraction Pathogenesis with Potential Diagnostic Utility.

    Chhor, Michael; Chen, Hao; Nikolić, Valentina N; Pavlović, Milan; Vučić, Rada M; Watson, Chris J; Ledwidge, Mark; McDonald, Kenneth; Robson, Tracy; McClements, Lana; et al. (2023-02-18)
    Heart failure (HF) is the leading cause of hospitalisations worldwide, with only 35% of patients surviving the first 5 years after diagnosis. The pathogenesis of HF with preserved ejection fraction (HFpEF) is still unclear, impeding the implementation of effective treatments. FK506-binding protein like (FKBPL) and its therapeutic peptide mimetic, AD-01, are critical mediators of angiogenesis and inflammation. Thus, in this study, we investigated-for the first time-FKBPL's role in the pathogenesis and as a biomarker of HFpEF. In vitro models of cardiac hypertrophy following exposure to a hypertensive stimulus, angiotensin-II (Ang-II, 100 nM), and/or AD-01 (100 nM), for 24 and 48 h were employed as well as human plasma samples from people with different forms of HFpEF and controls. Whilst the FKBPL peptide mimetic, AD-01, induced cardiomyocyte hypertrophy in a similar manner to Ang-II (p < 0.0001), when AD-01 and Ang-II were combined together, this process was abrogated (p < 0.01-0.0001). This mechanism appears to involve a negative feedback loop related to FKBPL (p < 0.05). In human plasma samples, FKBPL concentration was increased in HFpEF compared to controls (p < 0.01); however, similar to NT-proBNP and Gal-3, it was unable to stratify between different forms of HFpEF: acute HFpEF, chronic HFpEF and hypertrophic cardiomyopathy (HCM). FKBPL may be explored for its biomarker and therapeutic target potential in HFpEF.

    Rashed, Ahmed; Fitzpatrick, Orla M; Easty, David J; Collins, Dearbhaile; Mallet, Victoria; Milewski, Maciej; Egan, Keith; Grogan, Liam; Hennessy, Bryan T; Morris, Patrick G; et al. (2023-02-20)
    This was a single arm, non-interventional, prospective study. The primary endpoint was to determine the rate of neutropenia defined as ANC of < 1.0 × 109/L, during four cycles of dose dense AC with lipegfilgrastim support. The secondary endpoints were the incidence of febrile neutropenia, (temperature > 38 °C and ANC < 1.0 × 109/L), treatment delays, premature treatment cessation and toxicity.
