Blood Micro-sampling: An alternative blood collection method for radioiodine therapy dosimetry.

Purpose: Collecting venous blood samples from patients post administration of high therapeutic activities results in radiation exposure to staff collecting the blood. This study investigated the use of finger-tip capillary-blood collection as an alternative to the venous-blood collection method recommended by the European Association of Nuclear Medicine (EANM) dosimetry protocol for quantifying I concentration in the critical organ after therapeutic dose of I.

Methods: The study included differentiated thyroid cancer patients referred to a thyroid cancer centre at St James's Hospital, Ireland, for therapeutic and diagnostic oral administration of I.

Utility of the 70-Gene MammaPrint Assay for Prediction of Benefit From Extended Letrozole Therapy in the NRG Oncology/NSABP B-42 Trial.

Purpose: MammaPrint (MP) determines distant metastatic risk and may improve patient selection for extended endocrine therapy (EET). This study examined MP in predicting extended letrozole therapy (ELT) benefit in patients with early-stage breast cancer (BC) from the NSABP B-42 trial.

Patients And Methods: MP was tested in 1,866 patients randomly assigned to receive ELT or placebo.

Looking back to look forward: Has the time arrived for active management of obstetricians in placenta accreta spectrum?

Placenta accreta spectrum (PAS) is a relatively new obstetric condition which, until recently, was poorly understood. The true incidence is unknown because of the poor quality and heterogeneous diagnostic criteria. Classification systems have attempted to provide clarity on how to grade and diagnose PAS, but these are no longer reflective of our current understanding of PAS.

Meta-analysis of [F]FDG-PET/CT in pulmonary sarcoidosis.

Background: 18F-Fluorodeoxyglucose (FDG) PET/CT is emerging as a tool in the diagnosis and evaluation of pulmonary sarcoidosis, however, there is limited consensus regarding its diagnostic performance and prognostic value.

Method: A meta-analysis was conducted with PubMed, Science Direct, MEDLINE, Scopus, and CENTRAL databases searched up to and including September 2023. 1355 studies were screened, with seventeen (n = 708 patients) suitable based on their assessment of the diagnostic performance or prognostic value of FDG-PET/CT.

A qualitative study to understand the barriers and facilitators in smoking cessation practices among oncology health care practitioners in one health system.

Introduction: Despite the benefits of quitting smoking for those who have cancer, including improved health outcomes and reduced therapeutic toxicities, it is unclear how many people are supported in quit attempts during this time. Variations in the availability and provision of smoking cessation (SC) services are reported, with little understanding of the challenges and solutions. This co-designed study aimed to understand the perspectives of health care professionals (HCPs) working in oncology settings to engage in SC practices and identify recommendations for developing an SC pathway.

Unsupervised Exercise in Interstitial Lung Disease: A Delphi Study to Develop a Consensus Preparticipation Screening Tool for Lymphangioleiomyomatosis.

Background: Little research is available to provide practical guidance to health care providers for exercise preparticipation screening and referral of patients with interstitial lung diseases (ILDs), including lymphangioleiomyomatosis (LAM), to participate in remote, unsupervised exercise programs.

Research Question: What exercise preparticipation screening steps are essential to determine whether a patient with LAM is medically appropriate to participate in a remote, unsupervised exercise program?

Study Design And Methods: Sixteen experts in LAM and ILD participated in a two-round modified Delphi study, ranking their level of agreement for 10 statements related to unsupervised exercise training in LAM, with an a priori definition of consensus. Additionally, 60 patients with LAM completed a survey of the perceived risks and benefits of remote exercise training in LAM.

Challenges and Opportunities for Precision Surgery for Colorectal Liver Metastases.

The incidence of colorectal cancer and colorectal liver metastases (CRLM) is increasing globally due to an interaction of environmental and genetic factors. A minority of patients with CRLM have surgically resectable disease, but for those who have resection as part of multimodal therapy for their disease, long-term survival has been shown. Precision surgery-the idea of careful patient selection and targeting of surgical intervention, such that treatments shown to be proven to benefit on a population level are the optimal treatment for each individual patient-is the new paradigm of care.

SARS-CoV-2 infects neurons, astrocytes, choroid plexus epithelial cells and pericytes of the human central nervous system .

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection is associated with neurological sequelae including haemorrhage, thrombosis and ischaemic necrosis and encephalitis. However, the mechanism by which this occurs is unclear. Neurological disease associated with COVID-19 has been proposed to occur following direct infection of the central nervous system and/or indirectly by local or systemic immune activation.

Impact of previous pregnancy and BMI on cellular and serum immune activity from early to late pregnancy.

Immunological adaptions during pregnancy play a crucial role in healthy fetal development. Aberrant immune modifications however contribute to adverse pregnancy outcomes, which may be driven by maternal factors such as previous pregnancies and BMI. This secondary analysis of the MicrobeMom2 RCT investigates the changes to maternal inflammatory biomarkers derived from serum and stimulated peripheral blood mononuclear cells (PBMCs) during pregnancy, and the effects of previous pregnancies (parity) and BMI on maternal immune responses.

"Textbook outcome(s)" in colorectal surgery: a systematic review and meta-analysis.

Background: Textbook outcome (TO) is a composite measure used in surgery to evaluate post operative outcomes. No review has synthesised the evidence in relation to TO regarding the elements surgeons are utilising to inform their TO composite measure and the rates of TO achieved.

Methods: Our systematic review and meta analysis was conducted in line with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) recommendations.

Airway decision making in major head and neck surgery: Irish multicenter, multidisciplinary recommendations.

Major head and neck surgery poses a threat to perioperative airway patency. Adverse airway events are associated with significant morbidity, potentially leading to hypoxic brain injury and even death. Following a review of the literature, recommendations regarding airway management in head and neck surgery were developed with multicenter, multidisciplinary agreement among all Irish head and neck units.

Vertebral body and spinal cord infarction in a pile-driver operator with fibrocartilaginous disc embolism.

We describe the case of a male heavy machinery operator who presented from work with a rapidly evolving spinal cord syndrome. Spinal MRI revealed thoracic vertebral body and cord infarction and evolving mild disc prolapse attributed to fibrocartilaginous disc embolism (FCDE). FCDE should be considered as one of the aetiological mechanisms of acute spinal cord infarction in pile-driver/heavy machinery operators, especially in association with adjacent vertebral body infarction and intervertebral disc prolapse.

2024 European Thyroid Association Guidelines on diagnosis and management of genetic disorders of thyroid hormone transport, metabolism and action.

Impaired sensitivity to thyroid hormones encompasses disorders with defective transport of hormones into cells, reduced hormone metabolism, and resistance to hormone action. Mediated by heritable single-gene defects, these rare conditions exhibit different patterns of discordant thyroid function associated with multisystem phenotypes. In this context, challenges include ruling out other causes of biochemical discordance, making a diagnosis using clinical features together with the identification of pathogenic variants in causal genes, and managing these rare disorders with a limited evidence base.

Patient-specific modelling of contact characteristics in the ankle joint following triple arthrodesis in valgus, neutral and varus hindfoot positions.

The aim of the current study was to understand the importance of the joint alignment following triple arthrodesis by analysing the contact characteristics in a normal and arthritic ankle joint using a patient-specific numerical model developed using open source software. The alignment of the hindfoot with respect to tibia is calculated from CT scans and the ankle joint model was numerically analysed for neutral, valgus and varus positions in both normal and arthritic conditions. The contact area, the magnitude and distribution of the contact pressure on the articular surface of the talar dome was evaluated using a cell-centred Finite Volume Method implemented in open-source software OpenFOAM.
