The Royal Navy Operating Department Practitioner: Perioperative care on land and sea.
No full textRoyal Navy Operating Department Practitioners are employed in a number of different roles, during peacetime, humanitarian aid operations and periods of war. In recent times, Royal Navy Operating Department Practitioners have deployed on active operations in addition to working in NHS hospitals at home in the United Kingdom. This article will explore the different avenues and experiences of Operating Department Practitioners who are currently serving in the Royal Navy. The reader will then also gain an insight into the different echelons of care provided by the Defence Medical Services to the United Kingdom Armed Forces and Allied Nations. The article will then consider the unique experiences available to Royal Navy Operating Department Practitioners in this multi-faceted role which offers the opportunity to explore work patterns in different environments
Oxygenation strategies prior to and during prehospital emergency anaesthesia in UK HEMS practice (PREOXY survey).
No full textBACKGROUND
Maintaining effective oxygenation throughout the process of Pre-Hospital Emergency Anaesthesia (PHEA) is critical. There are multiple strategies available to clinicians to oxygenate patients both prior to and during PHEA. The optimal pre-oxygenation technique remains unclear, and it is unknown what techniques are being used by United Kingdom Helicopter Emergency Medical Services (HEMS). This study aimed to determine the current pre- and peri-PHEA oxygenation strategies used by UK HEMS services.
METHODS
An electronic questionnaire survey was delivered to all UK HEMS services between 05 July and 26 December 2019. Questions investigated service standard operating procedures (SOPs) and individual clinician practice regarding oxygenation strategies prior to airway instrumentation (pre-oxygenation) and oxygenation strategies during airway instrumentation (apnoeic oxygenation). Service SOPs were obtained to corroborate questionnaire replies.
RESULTS
Replies were received from all UK HEMS services (n = 21) and 40 individual clinicians. All services specified oxygenation strategies within their PHEA/RSI SOP and most referred to pre-oxygenation as mandatory (81%), whilst apnoeic oxygenation was mandatory in eight (38%) SOPs. The most commonly identified pre-oxygenation strategies were bag-valve-mask without PEEP (95%), non-rebreathable face mask (81%), and nasal cannula at high flow (81%). Seven (33%) services used Mapleson C circuits, whilst there were eight services (38%) that did not carry bag-valve-masks with PEEP valve nor Mapleson C circuits. All clinicians frequently used pre-oxygenation, however there was variability in clinician use of apnoeic oxygenation by nasal cannula. Nearly all clinicians (95%) reported manually ventilating patients during the apnoeic phase, with over half (58%) stating this was their routine practice. Differences in clinician pre-hospital and in-hospital practice related to availability of humidified high flow nasal oxygenation and Mapleson C circuits.
CONCLUSIONS
Pre-oxygenation is universal amongst UK HEMS services and is most frequently delivered by bag-valve-mask without PEEP or non-rebreathable face masks, whereas apnoeic oxygenation by nasal cannula is highly variable. Multiple services carry Mapleson C circuits, however many services are unable to deliver PEEP due to the equipment they carry. Clinicians are regularly manually ventilating patients during the apnoeic phase of PHEA. The identified variability in clinical practice may indicate uncertainty and further research is warranted to assess the impact of different strategies on clinical outcomes
The vicious cycle of functional neurological disorders: a synthesis of healthcare professionals' views on working with patients with functional neurological disorder.
No full textPURPOSE
The objective of this review was to synthesise studies which address the views of healthcare professionals (HCPs) towards patients with functional neurological disorder (FND).
METHODS
An interpretive systematised review was conducted. Seven databases were searched using a comprehensive search strategy (MEDLINE, EMBASE, AMED, CINAHL, PsychINFO, ProQuest Nursing and Allied Health, and Scopus). Qualitative studies and those using survey methods were included. An inductive approach to thematic analysis was used to identify concepts from the data and to synthesise the results.
RESULTS
The views of 2769 HCPs were represented in 11 included articles. The overarching theme across the articles was uncertainty: about making the diagnosis of FND, about professional roles, and about optimum management. Fear was also a common theme: of saying the wrong thing, of offending patients, or of breaking the therapeutic relationship.
CONCLUSIONS
If all HCPs felt uncertain about how to manage patients with FND and avoided them by passing them on to another discipline, then a "vicious cycle" is formed in which patients are passed from one professional to another but without receiving clear, honest information, or effective treatment. HCPs would benefit from increased training on FND and clear clinical pathways to alleviate feelings of uncertainty. Implications for rehabilitation Evidence-based or, at the very least, consensus-based multi-disciplinary care pathways for the assessment and treatment of patients with functional neurological disorder are required to improve equitability of services. Training packages for healthcare professionals need to be developed, evaluated and implemented in order to improve confidence of making and explaining the diagnosis and to reduce stigma of functional neurological disorders. Improved input for patients with functional neurological disorder is likely to occur if healthcare professionals are open, honest and use effective communication skills, both with their patients and fellow healthcare professionals
Incidence of sudden cardiac death in the young: a systematic review.
No full textOBJECTIVE
To summarise studies describing incidence of sudden cardiac death in a general population of young individuals to inform screening policy.
DESIGN
Systematic review.
DATA SOURCES
Database searches of MEDLINE, EMBASE and the Cochrane library (all inception to current) on 29 April 2019 (updated 16 November 2019), and forward/backward citation tracking of eligible studies.
STUDY ELIGIBILITY CRITERIA
All studies that reported incidence of sudden cardiac death in young individuals (12-39 years) in a general population, with no restriction on language or date. Planned subgroups were incidence by age, sex, race and athletic status (including military personnel).
DATA EXTRACTION
Two reviewers independently assessed study eligibility, extracted study data and assessed risk of bias using the Joanna Briggs Institute critical appraisal checklist for prevalence studies.
ANALYSIS
Reported incidence of sudden cardiac death in the young per 100 000 person-years.
RESULTS
38 studies that reported incidence across five continents. We identified substantial heterogeneity in population, sudden cardiac death definition, and case ascertainment methods, precluding meta-analysis. Median reported follow-up years was 6.97 million (IQR 2.34 million-23.70 million) and number of sudden cardiac death cases was 64 (IQR 40-251). In the general population, the median of reported incidence was 1.7 sudden cardiac death per 100 000 person-years (IQR 1.3-2.6, range 0.75-11.9). Most studies (n=14, 54%) reported an incidence between one and two cases per 100 000 person-years. Incidence was higher in males and older individuals.
CONCLUSIONS
This systematic review identified variability in the reported incidence of sudden cardiac death in the young across studies. Most studies reported an incidence between one and two cases per 100 000 person-years.

Cardiovascular risk knowledge in patients of South Asian origin living with rheumatoid arthritis: data from India and the UK.
No full textBackground
South Asians have a higher risk of cardiovascular disease (CVD). Rheumatoid arthritis (RA) increases the risk of premature atherosclerosis. We investigated whether there was a substantial difference in the level of CVD risk knowledge among patients of South Asian origin with RA in India and in the UK.
Methods
In this cross-sectional survey, patients of South Asian origin with RA from India and the UK were recruited from secondary care settings. Data were collected via Heart Disease Fact Questionnaire-Rheumatoid Arthritis (HDFQ-RA), a validated self-completion questionnaire. The HDFQ-RA was translated into Hindi and piloted among patients from South Asian background before use. Additionally, clinical and demographic data was collected.
Results
Among 118 patients from each country, 84% were female and they had similar age, education level, employment status and co-morbidities. Patients from India had longer disease duration (5.5 years versus 4.1 years ( = 0.012) whereas those from the UK had higher disease activity score (4.0 + 0.8 versus 3.1 + 0.7, < 0.01). Regarding modifiable risk factors for CVD only 51.2% from India and 51.3% in the UK were aware of them. However, awareness of the link between RA and increased risk of CVD was even more limited (32.8% in India and 34.4% in UK).
Conclusion
Patients of South Asians origin with RA from both countries had limited knowledge about CVD risk. There is a need to educate them about CVD risk during consultation, as this will result in better outcomes
Interventions to ameliorate reductions in muscle quantity and function in hospitalised older adults: a systematic review towards acute sarcopenia treatment.
No full textOBJECTIVE
Assimilate evidence for interventions to ameliorate negative changes in physical performance, muscle strength and muscle quantity in hospitalised older adults.
METHODS
We searched for articles using MEDLINE, Embase, CINAHL and Cochrane library using terms for randomised controlled trials, older adults, hospitalisation and change in muscle quantity, strength or physical performance. Two independent reviewers extracted data and assessed risk of bias. We calculated standardised mean differences for changes in muscle function/quantity pre- and post-intervention.
RESULTS
We identified 9,805 articles; 9,614 were excluded on title/abstract; 147 full texts were excluded. We included 44 studies including 4,522 participants; mean age 79.1. Twenty-seven studies (n = 3,417) involved physical activity interventions; a variety were trialled. Eleven studies involved nutritional interventions (n = 676). One trial involved testosterone (n = 39), two involved Growth Hormone (n = 53), one involved nandrolone (n = 29), and another involved erythropoietin (n = 141). Three studies (n = 206) tested Neuromuscular Electrical Stimulation. Evidence for effectiveness/efficacy was limited. Strongest evidence was for multi-component physical activity interventions. However, all studies exhibited at least some concerns for overall risk of bias, and considering inconsistencies of effect sizes across studies, certainty around true effect sizes is limited.
CONCLUSION
There is currently insufficient evidence for effective interventions to ameliorate changes in muscle function/quantity in hospitalised older adults. Multiple interventions have been safely trialled in heterogeneous populations across different settings. Treatment may need to be stratified to individual need. Larger scale studies testing combinations of interventions are warranted. Research aimed at understanding pathophysiology of acute sarcopenia will enable careful risk stratification and targeted interventions
Immunesenescence: A Predisposing Risk Factor for the Development of COVID-19?
No full textBearing a strong resemblance to the phenotypic and functional remodeling of the immune system that occurs during aging (termed immunesenescence), the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of Coronavirus disease 2019 (COVID-19), is characterized by an expansion of inflammatory monocytes, functional exhaustion of lymphocytes, dysregulated myeloid responses and the presence of highly activated senescent T cells. Alongside advanced age, male gender and pre-existing co-morbidities [e.g., obesity and type 2 diabetes (T2D)] are emerging as significant risk factors for COVID-19. Interestingly, immunesenescence is more profound in males when compared to females, whilst accelerated aging of the immune system, termed premature immunesenescence, has been described in obese subjects and T2D patients. Thus, as three distinct demographic groups with an increased susceptibility to COVID-19 share a common immune profile, Here, by focussing on three key aspects of an immune response, namely pathogen recognition, elimination and resolution, we address this question by discussing how immunesenescence may weaken or exacerbate the immune response to SARS-CoV-2. We also highlight how aspects of immunesenescence could render potential COVID-19 treatments less effective in older adults and draw attention to certain therapeutic options, which by reversing or circumventing certain features of immunesenescence may prove to be beneficial for the treatment of groups at high risk of severe COVID-19
Incomplete surgical excision of keratinocyte skin cancers: a systematic review and meta-analysis.
No full textBACKGROUND
Keratinocyte or non-melanoma skin cancer (NMSC) is the commonest malignancy worldwide. Usual treatment is surgical excision. Current guidelines underestimate incomplete excision rates.
OBJECTIVES
We aimed to determine the risk of incomplete excision of NMSCs through a systematic review and meta-analysis of primary clinical studies.
METHODS
A PRISMA-compliant systematic review and meta-analysis was performed using methodology proposed by Cochrane. A comprehensive search strategy was applied to MEDLINE, Embase, Scopus, CINAHL, EMCare, Cochrane Library and the grey literature (January 2000-27 November 2019). All studies were included except studies on Mohs micrographic surgery, frozen section or biopsies. Abstract screening and data extraction were performed in duplicate. The risk of bias was assessed using a tool for prevalence/incidence studies. The primary outcome was the proportion of incomplete surgical excisions. A random effects model for pooling of binominal data was used. Differences between proportions were assessed by sub-group meta-analysis and meta regression which were presented as risk ratios. PROSPERO CRD42019157936.
RESULTS
Searching identified 3477 records, with 110 studies included, comprising 53 796 patients with 106 832 basal cell carcinomas (BCC) and 21 569 squamous cell carcinomas (SCC). The proportion of incomplete excisions for BCC was 11·0% (95% CI 9·7-12·4%) and for SCC 9·4% (95% CI 7·6-11·4%). Incomplete excisions by specialty were: dermatology 6·2% BCCs, 4·7% SCCs; plastic surgery 9·4% BCCs, 8·2% SCCs; general practitioners 20·4% BCCs, 19·9% SCCs. The risk of incomplete excision for general practitioners was four times that of dermatologists for both BCC (RR 3·9 [95% CI 2·0-7·3]) and SCC (RR 4·8 [95% CI 1·0-22·8]). Studies were heterogenous (I =98%) and at high risk of bias.
CONCLUSIONS
The proportion of incomplete excisions is higher than previously reported. Excisions performed by specialists may lower the risk of incomplete excision
