ABSTRACT

BACKGROUND: Moderately severe or major trauma (injury severity score (ISS) > 8) is common, often resulting in physical and psychological problems and leading to difficulties in returning to work. Vocational rehabilitation (VR) can improve return to work/education in some injuries (e.g. traumatic brain and spinal cord injury), but evidence is lacking for other moderately severe or major trauma. METHODS: ROWTATE is an individually randomised controlled multicentre pragmatic trial of early VR and psychological support in trauma patients. It includes an internal pilot, economic evaluation, a process evaluation and an implementation study. Participants will be screened for eligibility and recruited within 12 weeks of admission to eight major trauma centres in England. A total of 722 participants with ISS > 8 will be randomised 1:1 to VR and psychological support (where needed, following psychological screening) plus usual care or to usual care alone. The ROWTATE VR intervention will be provided within 2 weeks of study recruitment by occupational therapists and where needed, by clinical psychologists. It will be individually tailored and provided for ≤ 12 months, dependent on participant need. Baseline assessment will collect data on demographics, injury details, work/education status, cognitive impairment, anxiety, depression, post-traumatic distress, disability, recovery expectations, financial stress and health-related quality of life. Participants will be followed up by postal/telephone/online questionnaires at 3, 6 and 12 months post-randomisation. The primary objective is to establish whether the ROWTATE VR intervention plus usual care is more effective than usual care alone for improving participants' self-reported return to work/education for at least 80% of pre-injury hours at 12 months post-randomisation. Secondary outcomes include other work outcomes (e.g. hours of work/education, time to return to work/education, sickness absence), depression, anxiety, post-traumatic distress, work self-efficacy, financial stress, purpose in life, health-related quality of life and healthcare/personal resource use. The process evaluation and implementation study will be described elsewhere. DISCUSSION: This trial will provide robust evidence regarding a VR intervention for a major trauma population. Evidence of a clinically and cost-effective VR intervention will be important for commissioners and providers to enable adoption of VR services for this large and important group of patients within the NHS.

ABSTRACT

The hospital based Redthread Youth Violence Intervention Programme (YVIP) utilises experienced youth workers to support 11-24 year olds following an episode of violent injury, assault or exploitation who present to the Emergency Department (ED) at the East Midlands Major Trauma Centre (MTC), Nottingham, UK. The YVIP aims to promote personal change with the aim of reducing the incidence of further similar events. We conducted a retrospective, observational, cohort study to examine the association between engagement with the YVIP and re-attendance rates to the ED following a referral to Redthread. We also examined factors associated with engagement with the full YVIP. We found that 573 eligible individuals were referred to the YVIP over two years. Assault with body parts 34.9% (n = 200) or a bladed object 29.8% (n = 171) were the commonest reason for referral. A prior event rate ratio (PERR) analysis was used to compare rates of attendance between those who did and did not engage with the full YVIP. Engagement was associated with a reduction in re-attendances of 51% compared to those who did not engage (PERR 0.49 [95% 0.28-0.64]). A previous attendance to the ED by an individual positively predicted engagement. (OR 2.82 [95% CI 1.07-7.42], P = 0.035). A weekend attendance (OR 0.26 [0.15-0.44], P<0.001) and a phone call approach (OR 0.25 [0.14-0.47], P = 0.001), rather than a face-to-face approach by a Redthread worker, negatively impacted engagement. In conclusion, assaults with or without a weapon contributed to a significant proportion of attendances among this age group. The Redthread YVIP was associated with reduced rates of re-attendance to the East Midlands MTC among young persons who engaged with the full programme.

ABSTRACT

Background: Centralisation of trauma care has been shown to be associated with improved patient outcomes. The establishment of Major Trauma Centres (MTC) and networks in England in 2012 allowed for centralisation of trauma services and specialties including hepatobiliary surgery. We aimed to investigate the outcomes for patients with hepatic injury over the last 17 years at a large MTC in England in relation to the MTC status of the centre. Methods: All patients who sustained liver trauma between 2005 and 2022 were identified using the Trauma Audit and Research Network database for a single MTC in the East Midlands. Mortality and complications were compared between patients before and after establishment of MTC status. Multivariable logistic regression models were used to determine the odds ratio (OR) and 95% confidence interval (95% CI) for complications according to MTC status, accounting for the potentially confounding variables of age, sex, severity of injuries and comorbidities for all patients, and the subgroup with severe liver trauma (AAST Grade IV and V). Results: There were 600 patients; the median age was 33 (IQR 22-52) years and 406/600 (68%) were male. There were no significant differences in 90-day mortality or length of stay between the pre- and post-MTC patients. Multivariable logistic regression models showed both lower overall complications [OR 0.24 (95% CI 0.14, 0.39); p < 0.001] and lower liver-specific complications [OR 0.21 (95% CI 0.11, 0.39); p < 0.001] in the post-MTC period. This was also the case in the severe liver injury subgroup (p = 0.008 and p = 0.002 respectively). Conclusions: Outcomes for liver trauma were superior in the post-MTC period even when adjusted for patient and injury characteristics. This was the case even though patients in this period were older with more comorbidities. These data support the centralisation of trauma services for those with liver injuries.

ABSTRACT

BACKGROUND: Mechanisms and patterns of injury in children are changing, with violent mechanisms becoming more prevalent over time. Government funding of services for children and young people has reduced nationally over the last decade. We aimed to investigate the trends in admissions of injured children to a Major Trauma Centre (MTC) and examine the relationship between injuries sustained by violent mechanisms and local authority funding of children and youth services within the same catchment area. METHODS: A 10-year observational study included all patients aged<18 years treated at a regional MTC between April 2012 and April 2022. Number of admissions with violent trauma, mechanism of injury, requirement for operative intervention and mortality were compared with published annual local authority expenditure reports. RESULTS: 1126 children were included; 71.3% were boys, with median age 11 years (IQR 3-16). There were 154/1126 (14%) children who were victims of violent trauma; they were more likely to be boys than children injured by non-violent mechanisms (84% vs 69%). The proportion of injuries attributed to violence increased over the study period at the same time as reductions in local authority funding of services for the early years, families and youth services. However, there were insufficient data to formally assess the interdependency between these factors. CONCLUSIONS: The proportion of injuries attributed to violence has increased over time, and government spending on specific children and young people's services has decreased over the same time period. Further work is needed to examine the interdependency between spending and violent injuries in children, and public health interventions to target violence-related injuries should take into account youth service funding.

ABSTRACT

PURPOSE: Children who live in areas of socioeconomic deprivation may be at higher risk of being victims of violent crime such as knife wounds. The current study investigated whether socioeconomic disparity was associated with higher risk of knife crime. METHODS: An observational study included patients aged ≤ 17 years at a UK Major Trauma Centre injured by knife trauma from 2016 to 2022. Indices of deprivation were recorded according to the zip code of residence and compared with those of all of England. These included Index of Multiple Deprivation (IMD); income; employment; education and skills; health and disability; crime; barriers to housing and services; living environment; and Income Deprivation Affecting Children Index (IDACI). RESULTS: There were 139 patients (96% male) with median age of 16 years. When compared with the whole of England, patients had worse indices of IMD (p = 0.021); income (p < 0.001); employment (p < 0.001); education and skills (p < 0.001); health and disability; and IDACI (p < 0.001). There were no significant differences in indices of crime, barriers to housing and services or living environment. CONCLUSIONS: Paediatric knife injury was associated with poor socioeconomic status in multiple domains. Focussed efforts to address socioeconomic disparities should be a priority as a public health measure for vulnerable children.

ABSTRACT

PURPOSE: To compare patterns and mechanisms of injuries during and after the UK Nationwide lockdown during the COVID-19 pandemic. METHODS: This prospective cohort study included all major trauma admissions during the 10-week period of the nationwide lockdown (09/03/2020-18/05/2020), compared with admissions in the 10-weeks following the full lifting of lockdown restrictions (04/07/20-12/09/2020). Differences in the volume, spectrum and mechanism of injuries presenting during and post-lockdown were compared using Fisher's exact and Chi-squared tests as appropriate. The associated risk of 30-day mortality was examined using univariable and multivariable logistic regression. RESULTS: A total of 692 major trauma admissions were included in this analysis. Of these, 237 patients were admitted during the lockdown and 455 patients were admitted post-lockdown. This represented a twofold increase in trauma admission between the two periods. Characteristically, both cohorts had a higher proportion of male patients (73.84% male during lockdown and 72.5% male post-lockdown). There was a noted shift in age groups between both cohorts with an overall more elderly population during lockdown (p = 0.0292), There was a significant difference in mechanisms of injury between the two cohorts. The 3-commonest mechanisms during the lockdown period were: Road traffic accidents (RTA)-31.22%, Falls of less than 2 m-26.58%, and falls greater than 2 m causing 22.78% of major trauma admissions. However, in the post-lockdown period RTAs represented 46.15% of all trauma admissions with falls greater than 2 m causing 17.80% and falls less than 2 m causing 15.16% of major trauma injuries. With falls in the elderly associated with an increased risk of mortality. In terms of absolute numbers, there was a twofold increase in major trauma injuries due to stabbings and shootings, rising from 25 admitted patients during the lockdown to 53 admitted patients post-lockdown. CONCLUSIONS: The lifting of lockdown restrictions resulted in a twofold increase in major trauma admissions that was also associated with significant changes in both the demographic and patterns of injuries with RTA's contributing almost half of all injury presentations. TRIAL REGISTRATION: This study was classed as a service evaluation and registered with the local audit department, registration number: 20-177C.

ABSTRACT

Animals must express the appropriate behavior that meets their most pressing physiological needs and their environmental context. However, it is currently unclear how alternative behavioral options are evaluated and appropriate actions are prioritized. Here, we describe how fruit flies choose between feeding and courtship; two behaviors necessary for survival and reproduction. We show that sex- and food-deprived male flies prioritize feeding over courtship initiation, and manipulation of food quality or the animal's internal state fine-tunes this decision. We identify the tyramine signaling pathway as an essential mediator of this decision. Tyramine biosynthesis is regulated by the fly's nutritional state and acts as a satiety signal, favoring courtship over feeding. Tyramine inhibits a subset of feeding-promoting tyramine receptor (TyrR)-expressing neurons and activates P1 neurons, a known command center for courtship. Conversely, the perception of a nutritious food source activates TyrR neurons and inhibits P1 neurons. Therefore, TyrR and P1 neurons are oppositely modulated by starvation, via tyramine levels, and food availability. We propose that antagonistic co-regulation of neurons controlling alternative actions is key to prioritizing competing drives in a context- dependent manner.

ABSTRACT

BACKGROUND: The global pandemic caused by SARS-CoV-2 has impacted population health and care delivery worldwide. As information emerges regarding the impact of "lockdown measures" and changes to clinical practice worldwide; there is no comparative information emerging from the United Kingdom with regard to major trauma. METHODS: This observational study from a UK Major Trauma Centre matched a cohort of patients admitted during a 10-week period of the SARS-CoV-2-pandemic (09/03/2020-18/05/2020) to a historical cohort of patients admitted during a similar time period in 2019 (11/03/2019-20/05/2019). Differences in demographics, Clinical Frailty Scale, SARS-CoV-2 status, mechanism of injury and injury severity were compared using Fisher's exact and Chi-squared tests. Univariable and multivariable logistic regression analyses examined the associated factors that predicted 30-days mortality. RESULTS: A total of 642 patients were included, with 405 in the 2019 and 237 in the 2020 cohorts, respectively. 4/237(1.69%) of patients in the 2020 cohort tested positive for SARS-CoV-2. There was a 41.5% decrease in the number of trauma admissions in 2020. This cohort was older (median 46 vs 40 years), had more comorbidities and were frail (p < 0.0015). There was a significant difference in mechanism of injury with a decrease in vehicle related trauma, but an increase in falls. There was a twofold increased risk of mortality in the 2020 cohort which in adjusted multivariable models, was explained by injury severity and frailty. A positive SARS-CoV-2 status was not significantly associated with increased mortality when adjusted for other variables. CONCLUSION: Patients admitted during the COVID-19 pandemic were older, frailer, more co-morbid and had an associated increased risk of mortality.

ABSTRACT

We introduce intermediate-plane holography, which substantially improves the ability of holographic trapping systems to project propagation-invariant modes of light using phase-only diffractive optical elements. Translating the mode-forming hologram to an intermediate plane in the optical train can reduce the need to encode amplitude variations in the field, and therefore complements well-established techniques for encoding complex-valued transfer functions into phase-only holograms. Compared to standard holographic trapping implementations, intermediate-plane holograms greatly improve diffraction efficiency and mode purity of propagation-invariant modes, and so increase their useful non-diffracting range. We demonstrate this technique through experimental realizations of accelerating modes and long-range tractor beams.
