AACC Guidance Document on Laboratory Investigation of Acute Kidney Injury.

Background: Acute kidney injury (AKI) is a sudden episode of kidney damage or failure affecting up to 15% of hospitalized patients and is associated with serious short- and long-term complications, mortality, and health care costs. Current practices to diagnose and stage AKI are variable and do not factor in our improved understanding of the biological and analytical variability of creatinine. In addition, the emergence of biomarkers, for example, cystatin C, insulin-like growth factor binding protein 7, and tissue inhibitor of metalloproteinases 2, and electronic notification tools for earlier detection of AKI, highlights the need for updated recommendations to address these developments.

Evaluation of Mannheim's Peritonitis Index in Prediction of Mortality in Patients with Non-traumatic Hollow Viscus Perforation Peritonitis.

Background: Hollow viscus perforation peritonitis is one of the commonest surgical emergencies with high mortality and morbidity. The objective of this study was to evaluate the effectiveness of Mannheim's peritonitis index in prediction of mortality in these patients.

Methods: This is a retrospective, observational cohort study in these patients managed in a single-center from January 1, 2013 to December 30, 2019.

Informed consent in interventional radiology - are we doing enough?

Objectives: Obtaining informed consent is a mandatory part of modern clinical practice. The aim of this study was to identify how often complications relating to Interventional Radiology (IR) procedures were discussed with the patient prior to the procedure.

Methods: A retrospective analysis of 100 patients who experienced a complication related to an IR procedure was performed.

Introduction: COVID-19 has had a significant impact on the entire health system. The trauma and orthopaedic service has been compelled to alter working practices to respond proactively and definitively to the crisis. The aim of this study is to summarise the impact of this outbreak on the trauma and orthopaedic workload and outline the response of the department.

Management of scaphoid fractures with CT scanning and virtual fracture clinic pathway reduces need for face-to-face clinic appointments.

Introduction: Early diagnosis is key to managing scaphoid fractures effectively. Computed tomography (CT) imaging can be effective if plain radiographs are negative. With increasing pressure on face-to-face clinics, consultant-led virtual fracture clinics (VFCs) are becoming increasingly popular.

International Validation of the Turkish Inappropriate Medication Use in the Elderly (TIME) Criteria Set: A Delphi Panel Study.

Objective: Explicit screening tools and implicit evaluation methods have been developed to assist healthcare professionals in the management of pharmacotherapy in older adults. As prescribing habits and locally available medications vary considerably between countries, guides tailored to the needs of specific regions may be required. We aimed to report the results of the international Delphi validation study for the Turkish Inappropriate Medication use in the Elderly (TIME) criteria set, which aims to detect inappropriate prescribing in older adults in Eastern Europe.

Medullary Thyroid Cancer Patient's Assessment of Quality of Life Tools: Results from the QaLM Study.

Background: Medullary thyroid cancer (MTC) is a neuroendocrine tumour and a rare variant of thyroid cancer with different aetiology, presentation and treatment to differentiated thyroid cancer. Currently available thyroid cancer-specific quality of life (QoL) tools focus on issues and treatments more relevant to patients with differentiated thyroid cancer and therefore may not address issues specific to a MTC diagnosis and cancer journey.

Method: This prospective multicentre randomised study involved 204 MTC patients completing four quality of life questionnaires (QOLQ) and stating their most and least preferred.

For four sixes, revisited.

Rarely is the extraction of the four first molars the ideal choice in the course of orthodontic treatment, particularly in older patients. Although this approach can offer distinct advantages in carefully selected patients, it is also associated with a number of well-recognized problems, including the extension of treatment times, anchorage management, and control of second molars during space closure. However, by careful use of contemporary materials and techniques, a high standard of treatment can be achieved, even in patients with complex malocclusions.

Splenic haematoma: a rare complication of colonoscopy.

Colonoscopy is the gold-standard tool to investigate the colon which also allows to biopsy or treat intraluminal pathologies. About 900 000 colonoscopies are performed annually in UK. It is considered a relatively safe procedure; however, some serious complications might take place.

COVID-19 - Changes in the presentation and management of shoulder and elbow trauma in a UK district general hospital orthopaedic department.

Introduction: COVID-19 has had a significant impact on healthcare systems. We aim to quantify the impact of this outbreak on shoulder and elbow trauma in our institution.

Methods: We prospectively collected data on patients presenting to our hospital with shoulder and elbow injuries during COVID-19.

Complicated sinusitis with sphenopalatine artery thrombosis in a COVID-19 patient: a case report.

COVID-19 has been a mystery against healthcare professionals. We herein report a rare presentation of complicated sinusitis with pre-septal cellulitis and hard palatal necrosis in a COVID-19 patient. A 52-year-old male was admitted to the hospital with typical COVID manifestations where he had two successive COVID-19 positive swabs.

Associations between frailty, physical performance, and renal biomarkers in older people with advanced chronic kidney disease.

Purpose: Impaired physical performance and frailty are common in older people with advanced chronic kidney disease but it is unclear which metabolic derangements contribute to these impairments. We, therefore, examined associations between renal biochemical markers and both physical performance and frailty in older people with advanced chronic kidney disease.

Methods: Secondary analysis of data from the BiCARB trial, which enrolled non-dialysing patients aged 60 and over, with chronic kidney disease stage 4/5, with serum bicarbonate < 22 mmol/L.

The role of interscalene brachial plexus block anaesthesia in arthroscopic shoulder surgery; a prospective study.

The choice of anaesthetic in shoulder surgery is an evolving field of research which has important implications for patient outcomes. We have performed a prospective study to assess the usability of an interscalene brachial plexus block (ISBPB) with sedation as the primary anaesthetic and analgesic for arthroscopic shoulder surgery. Our study assessed the requirements of analgesia peri-operatively and post operatively and found that patients had no requirement (n = 30) and minimal requirements with a low pain score (visual analogue score; mean 2.

The effect of the COVID-19 lockdown on the epidemiology of hip fractures in the elderly: a multicentre cohort study.

Introduction: The COVID-19 pandemic presented extraordinary challenges to the UK healthcare system. This study aimed to assess the impact of the COVID-19 lockdown on the epidemiology, treatment pathways and 30-day mortality rates of hip fractures. Outcomes of COVID-19 positive patients were compared against those who tested negative.

Nitric oxide (NO) elicits aminoglycoside tolerance in Escherichia coli but antibiotic resistance gene carriage and NO sensitivity have not co-evolved.

The spread of multidrug-resistance in Gram-negative bacterial pathogens presents a major clinical challenge, and new approaches are required to combat these organisms. Nitric oxide (NO) is a well-known antimicrobial that is produced by the immune system in response to infection, and numerous studies have demonstrated that NO is a respiratory inhibitor with both bacteriostatic and bactericidal properties. However, given that loss of aerobic respiratory complexes is known to diminish antibiotic efficacy, it was hypothesised that the potent respiratory inhibitor NO would elicit similar effects.

X Chromosome Contribution to the Genetic Architecture of Primary Biliary Cholangitis.

Background & Aims: Genome-wide association studies in primary biliary cholangitis (PBC) have failed to find X chromosome (chrX) variants associated with the disease. Here, we specifically explore the chrX contribution to PBC, a sexually dimorphic complex autoimmune disease.

Methods: We performed a chrX-wide association study, including genotype data from 5 genome-wide association studies (from Italy, United Kingdom, Canada, China, and Japan; 5244 case patients and 11,875 control individuals).

Body mass index changes: an assessment of the effects of age and gender using the e-norms method.

Background: To validate e-norms methodology in establishing a reference range for body mass index measures. A new method, the extrapolated norms (e-norms) method of determining normal ranges for biological variables is easy to use and recently was validated for several biological measurements. We aimed to determine whether this new method provides BMI results in agreement with established traditionally collected BMI values.
