Objectives To assess the feasibility of an intervention of midwifery support for antenatal pelvic floor muscle exercises (PFME) to prevent postnatal urinary incontinence (UI).Design Feasibility and pilot cluster randomised controlled trial. Clusters were community midwifery teams.Setting Community maternity antenatal care.Participants One hundred seventy-five women; 186 midwives.Intervention Midwifery training and resources for midwives and women to support antenatal PFME. Control clusters continued standard care.Outcomes Women reporting: that their midwife explained how to do PFME, PFME adherence and postpartum UI. Midwives reporting: pre-post-training PFME confidence, intervention acceptability. Fidelity of training delivery and implementation.Results Ninety-five midwives in intervention clusters; 91 midwives in control clusters. Of 998 women sent questionnaires, 175 responded: 15.8% in intervention, 16.4% in control clusters. Women’s characteristics in both trial arms were similar and characteristics of respondents and non-respondents were similar. Sixty-five percent (95% CI 56.9% to 72.4%) of women in intervention clusters reported their midwife explained how to do PFME vs 38% (95% CI 24.6% to 51.2%) in control clusters. Fifty percent (95% CI 24.1% to 77.1%) of women in intervention clusters vs 38% (95% CI 12.4% to 67.1%) in control clusters reported doing enough PFME to potentially prevent UI. Fourty-four percent (95% CI 32.0% to 56.1%) of women in intervention clusters reported UI vs 54% (95% CI 42.2% to 65.8%) in control clusters.Intervention training was delivered with fidelity and received positively. Midwives reported improvements in PFME confidence/knowledge (median increase of at least 1 point on a 0–4 scale for each of eight questions). Midwives (26%) most frequently reported insufficient time as an implementation barrier.Conclusions This pilot trial produced consistent new findings that training and resourcing midwives to teach and support pregnant women to undertake PFME is acceptable and feasible for women and midwives. It increased the number of women who are informed about PFME, with potential to improve PFME adherence and reduce postpartum UI. Recent changes to the National Health Service perinatal pelvic healthcare means a full trial is not possible.Trial registration number ISRCTN10833250.

Background: Carbapenem-resistant Enterobacterales (CRE) infections are an urgent public health threat. An estimated 12,700 CRE (including E. coli, Klebsiella spp., and Enterobacter spp.) infections occurred in the United States in 2020. While the estimated incidence of CRE infections has been relatively stable between 2012 and 2020, organism-specific trends, including those for organisms not typically included in CRE surveillance definitions, have not been described. We estimated the annual rate of carbapenem-resistant Enterobacterales infections, disaggregated by organism, from 2012 to 2022. Methods: Data on inpatient hospitalizations from a dynamic cohort of short-term acute care hospitals reporting microbiology data between 2012 and 2022 were obtained from the PINC AI Database and the BD Insights Research Database. We included patients with clinical isolates of E. coli, Enterobacter spp., Klebsiella spp., Citrobacter spp., Serratia marcescens, Proteus mirabilis, and Morganella spp. and sufficient susceptibility results to identify carbapenem resistance. We limited our analysis to incident isolates, defined as a patient’s first isolate of a given organism and carbapenem resistance phenotype in a 14-day period. We calculated the annual rate of carbapenem-resistant infections per 10,000 hospitalizations for each organism. Results: There were 3,018,792 incident isolates from 55.8 million hospitalizations included in the analysis. Overall, 31,226 incident carbapenem-resistant isolates were identified. The rate of carbapenem-resistant infections varied by organism and over time (Table 1). The rate of carbapenem-resistant Klebsiella spp. infections appeared to decline from 3.94 in 2012 to 2.44 infections per 10,000 hospitalizations in 2022. The rate of carbapenem-resistant Enterobacter spp. infections appeared to increase from 1.05 in 2012 to 1.44 infections per 10,000 hospitalizations in 2022. The rate of carbapenem-resistant E. coli infections also appeared to increase, from 0.61 in 2012 to 0.85 infections per 10,000 hospitalizations in 2022. Rates of carbapenem-resistant Proteus mirabilis, Morganella spp., Citrobacter spp., or Serratia marcescens infections were similar in 2022 compared to 2012. Conclusions: Disaggregating data by organism revealed heterogeneous trends, with apparent increases in rates of carbapenem-resistant Enterobacter spp. and E. coli infections and apparent decreases in rates of carbapenem-resistant Klebsiella spp. infections. Organism-specific CRE analyses may provide additional insight into CRE epidemiology.

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

BackgroundBurn injuries are the fourth most common type of trauma and are associated with substantial morbidity and mortality. The impact of burn injury is clinically significant as burn injuries often give rise to exuberant scarring. Hypertrophic scarring (HTS) is a particular concern as up to 70% of burns patients develop HTS. Laser therapy is used for treating HTS and has shown positive clinical outcomes, although the mechanisms remain unclear limiting approaches to improve its effectiveness. Emerging evidence has shown that fibroblasts and senescent cells are important modifiers of scarring. This study aims to investigate the cellular kinetics in HTS after laser therapy, with a focus on the association of scar reduction with the presence of senescent cells.MethodsWe will conduct a multicentre, intra-patient, single-blinded, randomised controlled longitudinal pilot study with parallel assignments to achieve this objective. 60 participants will be recruited to receive 3 interventional ablative fractional CO2 laser treatments over a 12-month period. Each participant will have two scars randomly allocated to receive either laser treatment or standard care. Biopsies will be obtained from laser-treated, scarred-no treatment and non-scarred tissues for immune-histological staining to investigate the longitudinal kinetics of p16INK4A+-senescent cells and fibroblast subpopulations (CD90+/Thy1+ and αSMA+). Combined subjective scar assessments including Modified Vancouver Scar Scale, Patient and Observer Scar Assessment Scale and Brisbane Burn Scar Impact Profile; and objective assessment tools including 3D-Vectra-H1 photography, DermaScan® Cortex, Cutometer® and ColoriMeter®DSMIII will be used to evaluate clinical outcomes. These will then be used to investigate the association between senescent cells and scar reduction after laser therapy. This study will also collect blood samples to explore the systemic biomarkers associated with the response to laser therapy.DiscussionThis study will provide an improved understanding of mechanisms potentially mediating scar reduction with laser treatment, which will enable better designs of laser treatment regimens for those living with HTS.Trial registrationClinicalTrials.gov: NCT04736251.

Background and Aim High rates of inflammatory bowel disease (IBD) have been documented in New Zealand (NZ) children. The objectives of this study were to describe the outcomes and disease course of childhood IBD in the first 3 years following diagnosis. Methods All children diagnosed with IBD in 2015 in NZ were included. Clinical data obtained during routine care for 3 years following diagnosis were analyzed. Growth parameters, disease activity scores, and blood parameters were compared at diagnosis and follow up. Results Three‐year outcome data were available for 48 of 51 children. At follow up, median age was 15.1 years, and 34 had Crohn's disease (CD), 11 had ulcerative colitis (UC), and three had IBD‐unclassified (IBDU). Although disease progression including development of perianal disease occurred in 13 (38%) of 34 children with CD, the majority (n = 30) had inflammatory disease at follow up. Disease extension occurred in 25% (2/8) of children initially diagnosed with UC. Of all IBD patients, the mean body mass index z‐score increased from −0.40 to +0.10 (P = 0.01). Disease activity scores reduced from diagnosis to follow up in both CD (mean pediatric Crohn's disease activity index 35–6, P

Background: The incidence of knife-related injuries is rising across the UK. This study aimed to determine the spectrum of knife-related injuries in a major UK city, with regards to patient and injury characteristics. A secondary aim was to quantify their impact on secondary care resources. Methods: Observational study of patients aged 16+ years admitted to a major trauma centre following knife-related injuries resulting from interpersonal violence (May 2015 to April 2018). Patients were identified using Emergency Department and discharge coding, blood bank and UK national Trauma Audit and Research prospective registries. Patient and injury characteristics, outcome and resource utilisation were collected from ambulance and hospital records. Findings: 532 patients were identified; 93% male, median age 26 years (IQR 20–35). Median injury severity score was 9 (IQR 3–13). 346 (65%) underwent surgery; 133 (25%) required intensive care; 95 (17·9%) received blood transfusion. Median length of stay was 3·3 days (IQR 1·7–6·0). In-hospital mortality was 10/532 (1·9%). 98 patients (18·5%) had previous attendance with violence-related injuries. 24/37 females (64·9%) were injured in a domestic setting. Intoxication with alcohol (19·2%) and illicit drugs (17·6%) was common. Causative weapon was household knife in 9%, knife (other/unspecified) in 38·0%, machete in 13·9%, small folding blade (2·8%) and, unrecorded in 36·3%. Interpretation: Knife injuries constitute 12·9% of trauma team workload. Violence recidivism and intoxication are common, and females are predominantly injured in a domestic setting, presenting opportunities for targeted violence reduction interventions. 13·9% of injuries involved machetes, with implications for law enforcement strategies.

Abstract: Soluble glycoprotein VI (sGPVI) is shed from the platelet surface and is a marker of platelet activation in thrombotic conditions. We assessed sGPVI levels together with patient and clinical parameters in acute and chronic inflammatory conditions, including patients with thermal injury and inflammatory bowel disease and patients admitted to the intensive care unit (ICU) for elective cardiac surgery, trauma, acute brain injury, or prolonged ventilation. Plasma sGPVI was measured by enzyme-linked immunosorbent assay and was elevated on day 14 after thermal injury, and was higher in patients who developed sepsis. sGPVI levels were associated with sepsis, and the value for predicting sepsis was increased in combination with platelet count and Abbreviated Burn Severity Index. sGPVI levels positively correlated with levels of D-dimer (a fibrin degradation product) in ICU patients and patients with thermal injury. sGPVI levels in ICU patients at admission were significantly associated with 28- and 90-day mortality independent of platelet count. sGPVI levels in patients with thermal injury were associated with 28-day mortality at days 1, 14, and 21 when adjusting for platelet count. In both cohorts, sGPVI associations with mortality were stronger than D-dimer levels. Mechanistically, release of GPVI was triggered by exposure of platelets to polymerized fibrin, but not by engagement of G protein-coupled receptors by thrombin, adenosine 5′-diphosphate, or thromboxane mimetics. Enhanced fibrin production in these patients may therefore contribute to the observed elevated sGPVI levels. sGPVI is an important platelet-specific marker for platelet activation that predicts sepsis progression and mortality in injured patients.

Abstract Proximal femoral fractures are a major public health concern with estimated annual direct and social costs amounting to £2 billion and average 30-day mortality risk of 7.5%. In response to the recent debate over out-of-hours hospital provision we investigated the ‘weekend effect’ at a major trauma centre, caring for acute injuries. A single centre, multi-surgeon review of 2060 patients performed. The distribution of patient and treatment variables compared in patients admitted on a weekday or the weekend. Fewer patients met performance indicators during weekend admission, time to surgery (63 vs. 71%) and time to geriatric review (86 vs. 91%). Weekend admission 30-day mortality was marginally lower than weekday (9.7% vs. 10.2%, OR 0.94, 95% CI 0.67 to 1.32, p = 0.7383). Increasing age, female gender, co-morbidities and confusion increased mortality risk. Binary regression analysis including these variables found no significant ‘weekend effect’. Despite the unit observing an increasing workload in the last five years, with meticulous workforce planning, senior doctor provisions and careful use of resources, it is possible to provide a seven-day fracture neck of femur service with no variation in thirty-day mortality by the day of admission.

Summary: Background: There is ongoing debate on the clinical benefits of antibiotic prophylaxis for reducing pelvic infection after miscarriage surgery. We aimed to study the cost-effectiveness of antibiotic prophylaxis in the surgical management of miscarriage in low-income countries. Methods: We did an incremental cost-effectiveness analysis using data from 3412 women recruited to the AIMS trial, a randomised, double-blind, placebo-controlled trial designed to evaluate the effectiveness of antibiotic prophylaxis in the surgical management of miscarriage in Malawi, Pakistan, Tanzania, and Uganda. Economic evaluation was done from a health-care-provider perspective on the basis of the outcome of cost per pelvic infection avoided within 2 weeks of surgery. Pelvic infection was broadly defined by the presence of clinical features or the clinically identified need to administer antibiotics. We used non-parametric bootstrapping and multilevel random effects models to estimate incremental mean costs and outcomes. Decision uncertainty was shown via cost-effectiveness acceptability frontiers. The AIMS trial is registered with the ISRCTN registry, number ISRCTN97143849. Findings: Between June 2, 2014, and April 26, 2017, 3412 women were assigned to receive either antibiotic prophylaxis (1705 [50%] of 3412) or placebo (1707 [50%] of 3412) in the AIMS trial. 158 (5%) of 3412 women developed pelvic infection within 2 weeks of surgery, of whom 68 (43%) were in the antibiotic prophylaxis group and 90 (57%) in the placebo group. There is 97–98% probability that antibiotic prophylaxis is a cost-effective intervention at expected thresholds of willingness-to-pay per additional pelvic infection avoided. In terms of post-surgery antibiotics, the antibiotic prophylaxis group was US$0·27 (95% CI −0·49 to −0·05) less expensive per woman than the placebo group. A secondary analysis, a sensitivity analysis, and all subgroup analyses supported these findings. Antibiotic prophylaxis, if implemented routinely before miscarriage surgery, could translate to an annual total cost saving of up to $1·4 million across the four participating countries and up to $8·5 million across the two regions of sub-Saharan Africa and south Asia. Interpretation: Antibiotic prophylaxis is more effective and less expensive than no antibiotic prophylaxis. Policy makers in various settings should be confident that antibiotic prophylaxis in miscarriage surgery is cost-effective.

Background: Eleven million people suffer a fire-related injury worldwide every year, and 71% have significant scarring. Pressure garment therapy (PGT) is a standard part of burn scar management, but there is little evidence of its clinical effectiveness or cost-effectiveness. Objective: To identify the barriers to, and the facilitators of, conducting a randomised controlled trial (RCT) of burn scar management with and without PGT and test whether or not such a trial is feasible. Design: Web-based surveys, semistructured individual interviews, a pilot RCT including a health economic evaluation and embedded process evaluation. Setting: UK NHS burns services. Interviews and the pilot trial were run in seven burns services. Participants: Thirty NHS burns services and 245 staff provided survey responses and 15 staff participated in individual interviews. Face-to-face interviews were held with 24 adult patients and 16 parents of paediatric patients who had undergone PGT. The pilot trial recruited 88 participants (57 adults and 31 children) who were at risk of hypertrophic scarring and were considered suitable for scar management therapy. Interviews were held with 34 participants soon after recruitment, with 23 participants at 12 months and with eight staff from six sites at the end of the trial. Interventions: The intervention was standard care with pressure garments. The control was standard care comprising scar management techniques involving demonstration and recommendations to undertake massage three or four times per day with moisturiser, silicone treatment, stretching and other exercises. Main outcome measures: Feasibility was assessed by eligibility rates, consent rates, retention in allocated arms, adherence with treatment and follow-up and completion of outcome assessments. The outcomes from interview-based studies were core outcome domains and barriers to, and facilitators of, trial participation and delivery. Results: NHS burns services treat 2845 patients per annum (1476 paediatric and 1369 adult) and use pressure garments for 6–18 months, costing £2,171,184. The majority of staff perceived a need for a RCT of PGT, but often lacked equipoise around the research question and PGT as a treatment. Strong views about the use of PGT have the potential to influence the conduct of a full-scale RCT. A range of outcome domains was identified as important via the qualitative research: perceptions of appearance, specific scar characteristics, function, pain and itch, broader psychosocial outcomes and treatment burden. The outcome tools evaluated in the pilot trial did not cover all of these domains. The planned 88 participants were recruited: the eligibility rate was 88% [95% confidence interval (CI) 83% to 92%], the consent rate was 47% (95% CI 40% to 55%). Five (6%) participants withdrew, 14 (16%) were lost to follow-up and 8 (9%) crossed over. Adherence was as in clinical practice. Completion of outcomes was high for adult patients but poorer from parents of paediatric patients, particularly for quality of life. Sections on range of movement and willingness to pay were found to be challenging and poorly completed. Limitations: The Brisbane Burn Scar Impact Profile appears more suitable in terms of conceptual coverage than the outcome scales that were used in the trial but was not available at the time of the study. Conclusions: A definitive RCT of PGT in burn scar management appears feasible. However, staff attitudes to the use of pressure garments may lead to biases, and the provision of training and support to sites and an ongoing assessment of trial processes are required. Future work: We recommend that any future trial include an in-depth mixed-methods recruitment investigation and a process evaluation to account for this.
