Awareness of radiation risks by medical students & referrers requesting radiological examinations in the North of Scotland: an audit.

Introduction: Radiological imaging has played an important role in diagnostic medicine for over a century, though it is known to contribute to dermatological conditions, cataracts, and cancer. The associated risk of harm has led to the introduction of protective regulations around the world. Present-day NHS clinicians are increasingly requesting and relying on diagnostic imaging.

Understanding and reporting odds ratios as rate-ratio estimates in case-control studies.

Background: We noted that there remains some confusion in the health-science literature on reporting sample odds ratios as estimated rate ratios in case-control studies.

Methods: We recap historical literature that definitively answered the question of when sample odds ratios (ORs) from a case-control study are consistent estimators for population rate ratios. We use numerical examples to illustrate the magnitude of the disparity between sample ORs in a case-control study and population rate ratios when sufficient conditions for them to be equal are not satisfied.

Impact on emergency and elective hospital-based care in Scotland over the first 12 months of the pandemic: interrupted time-series analysis of national lockdowns.

Objectives: COVID-19 has resulted in the greatest disruption to National Health Service (NHS) care in its over 70-year history. Building on our previous work, we assessed the ongoing impact of pandemic-related disruption on provision of emergency and elective hospital-based care across Scotland over the first year of the pandemic.

Design: We undertook interrupted time-series analyses to evaluate the impact of ongoing pandemic-related disruption on hospital NHS care provision at national level and across demographics and clinical specialties spanning the period 29 March 2020-28 March 2021.

First dose ChAdOx1 and BNT162b2 COVID-19 vaccinations and cerebral venous sinus thrombosis: A pooled self-controlled case series study of 11.6 million individuals in England, Scotland, and Wales.

Background: Several countries restricted the administration of ChAdOx1 to older age groups in 2021 over safety concerns following case reports and observed versus expected analyses suggesting a possible association with cerebral venous sinus thrombosis (CVST). Large datasets are required to precisely estimate the association between Coronavirus Disease 2019 (COVID-19) vaccination and CVST due to the extreme rarity of this event. We aimed to accomplish this by combining national data from England, Scotland, and Wales.

Uptake, effectiveness and safety of COVID-19 vaccines in children and young people in Scotland: Protocol for early pandemic evaluation and enhanced surveillance of COVID-19 (EAVE II).

Background: The dynamics of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission and severity of disease among children and young people (CYP) across different settings are of considerable clinical, public health and societal interest. Severe COVID-19 cases, requiring hospitalisations, and deaths have been reported in some CYP suggesting a need to extend vaccinations to these age groups. As part of the ongoing Early Pandemic Evaluation and Enhanced Surveillance of COVID-19 (EAVE II) study, we aim to investigate the uptake, effectiveness and safety of COVID-19 vaccines in children and young people (CYP) aged 0 to 17 years in Scotland.

The unspoken benefit of participation in a clinical trial.

Background: Publicly funded trials do not usually offer financial incentives to volunteers. An intensive level of medical care could act as an additional motivator for participation. Our aim was to establish whether patients may draw any clinical benefit from volunteering in a clinical trial.

Regulatory T Cells in Pregnancy Adverse Outcomes: A Systematic Review and Meta-Analysis.

Background: Several studies report the role of Regulatory T-cells (Tregs) in the pathophysiology of pregnancy adverse outcomes.

Objective: The aim of this systematic review and meta-analysis was to determine whether there is an association between regulatory T cell levels and pregnancy adverse outcomes (PAOs), including pre-eclampsia and preterm birth (PTB).

Method: Literature searches were conducted in PubMed/MEDLINE, Embase, and Cochrane CENTRAL databases.

Teaching Benign Paroxysmal Positional Vertigo to Emergency Medicine Residents by Using Gagne's Nine Steps of Instructional Design.

Introduction: Patients commonly seek medical advice with dizziness symptoms. One of the common subtypes of dizziness is benign paroxysmal positional vertigo (BPPV). The American Academy of Neurology recommends that physicians should be trained in the physical maneuvers for the treatment of BPPV.

COVID-19 hospital admissions and deaths after BNT162b2 and ChAdOx1 nCoV-19 vaccinations in 2·57 million people in Scotland (EAVE II): a prospective cohort study.

Background: The UK COVID-19 vaccination programme has prioritised vaccination of those at the highest risk of COVID-19 mortality and hospitalisation. The programme was rolled out in Scotland during winter 2020-21, when SARS-CoV-2 infection rates were at their highest since the pandemic started, despite social distancing measures being in place. We aimed to estimate the frequency of COVID-19 hospitalisation or death in people who received at least one vaccine dose and characterise these individuals.

Hepatobiliary complications from ruptured silicone breast implants - a comprehensive literature review.

Cronin and Gerow first introduced silicone breast implants in 1962; they now serve as first-line for breast augmentation. Breast augmentation is effective in restoring both physical and psychological well-being in women post-mastectomy. Many studies in the literature on complications of silicone breast implant rupture focus on lymphomas and capsular contractures.

Current Use, Perceived Barriers, and Learning Preference of Point of Care Ultrasound (POCUS) in the Emergency Medicine in Qatar - A Mixed Design.

Introduction: Point of care ultrasound (POCUS) has been a part of emergency medicine (EM) training for almost two decades. EM training program has a very broad and rigorous POCUS curricula which, in several cases, does not translate to routine application in clinical settings. This study therefore sought to compare the indications, utilization, barriers, and preferred POCUS educational method in a large Middle Eastern academic EM.

Interim findings from first-dose mass COVID-19 vaccination roll-out and COVID-19 hospital admissions in Scotland: a national prospective cohort study.

Background: The BNT162b2 mRNA (Pfizer-BioNTech) and ChAdOx1 nCoV-19 (Oxford-AstraZeneca) COVID-19 vaccines have shown high efficacy against disease in phase 3 clinical trials and are now being used in national vaccination programmes in the UK and several other countries. Studying the real-world effects of these vaccines is an urgent requirement. The aim of our study was to investigate the association between the mass roll-out of the first doses of these COVID-19 vaccines and hospital admissions for COVID-19.

Medical student assessments-frequency of radiological images used: a national study.

Objectives: Assessments are a key part of life for medical students at University. We know there is variation in these assessments across Universities. The aims of this study were to expatiate summative assessments in Scottish Medical Schools and to examine how frequently radiological images feature in them.

Student perceptions of a sequential objective structured clinical examination.

Background: Well-designed objective structured clinical examinations (OSCEs) are reliable and valid, but expensive. The sequential OSCE (sOSCE) aims to balance robustness with affordability. In a sOSCE all students undertake a screening test (Day 1), with 'failing' or 'borderline' candidates sitting a second examination (Day 2).

External injuries, trauma and avoidable deaths in Agincourt, South Africa: a retrospective observational and qualitative study.

Objective: Injury burden is highest in low-income and middle-income countries. To reduce avoidable deaths, it is necessary to identify health system deficiencies preventing timely, quality care. We developed criteria to use verbal autopsy (VA) data to identify avoidable deaths and associated health system deficiencies.

Incident adverse drug reactions in geriatric inpatients: a multicentred observational study.

Background: Adverse drug reactions (ADRs) are common in older adults and frequently have serious clinical and economic consequences. This study was conducted as a feasibility study for a randomized control trial (RCT) that will investigate the efficacy of a software engine to optimize medications and reduce incident (in-hospital) ADRs. This study's objectives were to (i) establish current incident ADR rates across the six sites participating in the forthcoming RCT and (ii) assess whether incident ADRs are predictable.

Does intranasal steroid spray technique affect side effects and compliance? Results of a patient survey.

Background: Intranasal steroid sprays are fundamental in the medical management of inflammatory rhinological conditions. Side effects are common, but these may be related to the method of application rather than the medication itself.

Methods: A survey was distributed to patients using intranasal steroid sprays at the ENT out-patient clinic at Aberdeen Royal Infirmary over three months.

Safe use of anti-CD154 monoclonal antibody in pig islet xenotransplantation in monkeys.

Anti-CD154mAb is a powerful co-stimulation blockade agent that is efficacious in preventing rejection, even in xenogeneic settings. It has been used in the majority of successful long-term pig-to-non-human primate islet transplantation models. However, its clinical use was halted as a result of thromboembolic complications that were also observed in preclinical and clinical organ transplantation models.

Metabolic impairment in heart failure: the myocardial and systemic perspective.

Although bioenergetic starvation is not a new concept in heart failure (HF), recent research has led to a growing appreciation of the complexity of metabolic aspects of HF pathophysiology. All steps of energy extraction, transfer, and utilization are affected, and structural metabolism is impaired, leading to compromised functional integrity of tissues. Not only the myocardium, but also peripheral tissues and organs are affected by metabolic failure, resulting in a global imbalance between catabolic and anabolic signals, leading to tissue wasting and, ultimately, to cachexia.

Twelve-year follow-up of conservative management of postnatal urinary and faecal incontinence and prolapse outcomes: randomised controlled trial.

Objective: To determine the long-term (12-year) effects of a conservative nurse-led intervention for postnatal urinary incontinence.

Design: Follow-up of a randomised controlled trial.

Setting: Community-based intervention in three centres (in the UK and New Zealand).
