RESUMEN

INTRODUCTION: This study aims to evaluate the association between trauma center type, verification level, and clinical outcomes in pediatric trauma patients with moderate and severe isolated blunt traumatic brain injury (TBI). METHODS: This is a retrospective cohort study utilizing the American College of Surgeons (ACS) Trauma Quality Program (TQP) Participant Use File (PUF) database from 2017 to 2021. Severely injured pediatric (<18 years) trauma patients with isolated moderate and severe TBI (AIS head >2, all other body regions <3) were included. Outcomes included in-hospital mortality, discharge disposition, intensive care unit length-of-stay (ICU-LOS), and ventilator-free days (VFDs). RESULTS: Patients treated at a level-I combined adult and pediatric trauma centers (CTCs) had significantly lower odds of in-hospital mortality than those treated at adult trauma centers (ATCs) (OR .495, 95% CI 0.291-.841, P = .009). Patients treated at level-I pediatric trauma centers (PTCs) (OR 2.726, 95% CI 2.059-3.609, P < .001) and level-II PTCs (OR 6.18, 95% CI 3.402-11.239, P < .001) were significantly more likely to be discharged home than equivalent-level ATCs. CONCLUSION: Pediatric patients with isolated blunt moderate and severe TBI treated at level-I PTCs and CTCs had reduced odds of in-hospital mortality compared to level-I ATCs. Patients at level I and II PTCs had significantly higher odds of discharge home than those at equivalent-level CTCs and ATCs.

RESUMEN

INTRODUCTION: We aim to evaluate the impact of recent changes in the residency matching process on surgical specialties' applicants and programs to offer recommendations on residency selection and matching processes. METHODS: We utilized five databases while employing a Boolean query to search for studies from 2015 to March 2024. The search selection focused on factors and recent changes influencing residency match results across surgical specialties, including USMLE Step 1 pass/fail, research productivity, interview structure, and preference and geographic signaling. RESULTS: The shift of the USMLE Step 1 to a pass/fail scoring system revealed a consensus among surgical program directors (PDs) and applicants not in favor of the change due to the emphasis on additional application elements. Research productivity was identified as a significant factor, especially in neurosurgery (with an average of 18.3 publications per applicant) and vascular surgery (8.3 publications), indicating a positive correlation between the number of publications and match outcomes. The adoption of virtual interviews has been well-received by both applicants and PDs, leading to an increase in the number of interviews offered and applicants. The implementation of preference and geographic signaling mechanisms has improved interview rates for applicants who utilize them. CONCLUSION: The transition to a pass/fail USMLE Step 1 has raised concerns among surgical specialties, necessitating a greater focus on Step 2 scores and research productivity. Virtual interviews and signaling have improved the accessibility and reach of the residency application process, however, the full impact of these changes on the perception of applicant-program fit remains unclear.

RESUMEN

INTRODUCTION: Although non-accidental trauma continues to be a leading cause of morbidity and mortality among children in the United States, the underlying factors leading to NAT are not well characterized. We aim to review reporting practices, clinical outcomes, and associated disparities among pediatric trauma patients experiencing NAT. METHODS: A literature search utilizing PubMed, Google Scholar, EMBASE, ProQuest, and Cochrane was conducted from database inception until April 6, 2023. This review includes studies that assessed pediatric (age <18) trauma patients treated for NAT in the United States emergency departments. The evaluated outcome was in-hospital mortality rates stratified by race, age, sex, insurance status, and socioeconomic advantage. RESULTS: The literature search yielded 2641 initial articles, and after screening and applying inclusion and exclusion criteria, 15 articles remained. African American pediatric trauma patients diagnosed with NAT had higher mortality odds than white patients, even when adjusting for comparable injury severity. Children older than 12 mo experienced higher mortality rates compared to those younger than 12 mo, although some studies did not find a significant association between age and mortality. Uninsured insurance status was associated with the highest mortality rate, followed by Medicaid and private insurance. No significant association between sex and mortality or socioeconomic advantage and mortality was observed. CONCLUSIONS: Findings showed higher in-hospital mortality among African American pediatric trauma patients experiencing child abuse, and in patients 12 mo or older. Medicaid and uninsured pediatric patients faced higher mortality odds from their abuse compared to privately insured patients.

RESUMEN

INTRODUCTION: We aim to evaluate the association of early versus late venous thromboembolism (VTE) prophylaxis on in-hospital mortality among patients with severe blunt isolated traumatic brain injuries. METHODS: Data from the American College of Surgeons Trauma Quality Program Participant Use File for 2017-2021 were analyzed. The target population included adult trauma patients with severe isolated traumatic brain injury (TBI). VTE prophylaxis types (low molecular weight heparin and unfractionated heparin) and their administration timing were analyzed in relation to in-hospital complications and mortality. RESULTS: The study comprised 3609 patients, predominantly Caucasian males, with an average age of 48.5 y. Early VTE prophylaxis recipients were younger (P < 0.01) and more likely to receive unfractionated heparin (P < 0.01). VTE prophylaxis later than 24 h was associated with a higher average injury severity score and longer intensive care unit stays (P < 0.01). Logistic regression revealed that VTE prophylaxis later than 24 h was associated with significant reduction of in-hospital mortality by 38% (odds ratio 0.62, 95% confidence interval 0.40-0.94, P = 0.02). Additionally, low molecular weight heparin use was associated with decreased mortality odds by 30% (odds ratio 0.70, 95% confidence interval 0.55-0.89, P < 0.01). CONCLUSIONS: VTE prophylaxis later than 24 h is associated with a reduced risk of in-hospital mortality in patients with severe isolated blunt TBI, as opposed to VTE prophylaxis within 24 h. These findings suggest the need for timely and appropriate VTE prophylaxis in TBI care, highlighting the critical need for a comprehensive assessment and further research concerning the safety and effectiveness of VTE prophylaxis in these patient populations.

RESUMEN

Outcome after traumatic brain injury (TBI) is typically assessed using the Glasgow outcome scale extended (GOSE) with levels from 1 (death) to 8 (upper good recovery). Outcome prediction has classically been dichotomized into either dead/alive or favorable/unfavorable outcome. Binary outcome prediction models limit the possibility of detecting subtle yet significant improvements. We set out to explore different machine learning methods with the purpose of mapping their predictions to the full 8 grade scale GOSE following TBI. The models were set up using the variables: age, GCS-motor score, pupillary reaction, and Marshall CT score. For model setup and internal validation, a total of 866 patients could be included. For external validation, a cohort of 369 patients were included from Leuven, Belgium, and a cohort of 573 patients from the US multi-center ProTECT III study. Our findings indicate that proportional odds logistic regression (POLR), random forest regression, and a neural network model achieved accuracy values of 0.3-0.35 when applied to internal data, compared to the random baseline which is 0.125 for eight categories. The models demonstrated satisfactory performance during external validation in the data from Leuven, however, their performance were not satisfactory when applied to the ProTECT III dataset.

RESUMEN

The aim of this study was to describe the opinions of patients undergoing treatment with originator biologics and medical consultants managing their conditions and identify the barriers and enablers to transitioning from originator biologics to equivalent biosimilars. This study was undertaken prior to biosimilar switching at a large teaching hospital in the United Kingdom. Five gastroenterology, rheumatology, and dermatology consultants were interviewed. Two focus groups were conducted with patients prescribed infliximab (n = 2) and etanercept originators (n = 7). Four main themes emerged, as follows: (1) 'Benefit to the NHS'; (2) 'Evidence for efficacy and safety'; (3) 'Team roles'; and (4) 'Effective communication during switching', with sub-themes such as (4a) 'What patients want to know' and (4b) 'How it should be communicated'. Recognition of the ability to save NHS money was an enabler for both patients and consultants, with patients wanting to be reassured that the money saved would be used to benefit other patients. Consultants did not always believe that biosimilars had similar efficacy as the originators or that the manufacturing standards were the same. Effective interventions to address these concerns are required. Offering patients the opportunity to revert back to their originator if necessary was seen as an enabler, as was the provision of readily available mechanisms for reporting suspected adverse events resulting from switching. The role of pharmacy in the process of switching from originator biologics to biosimilars can range from educating consultants regarding the safety and efficacy of biosimilars, explaining the rationale for switching patients, and providing a route for reporting adverse events.

RESUMEN

Recent work indicates that feralisation is not a simple reversal of domestication, and therefore raises questions about the predictability of evolution across replicated feral populations. In the present study we compare genes and traits of two independently established feral populations of chickens (Gallus gallus) that inhabit archipelagos within the Pacific and Atlantic regions to test for evolutionary parallelism and/or divergence. We find that feral populations from each region are genetically closer to one another than other domestic breeds, despite their geographical isolation and divergent colonisation histories. Next, we used genome scans to identify genomic regions selected during feralisation (selective sweeps) in two independently feral populations from Bermuda and Hawaii. Three selective sweep regions (each identified by multiple detection methods) were shared between feral populations, and this overlap is inconsistent with a null model in which selection targets are randomly distributed throughout the genome. In the case of the Bermudian population, many of the genes present within the selective sweeps were either not annotated or of unknown function. Of the nine genes that were identifiable, five were related to behaviour, with the remaining genes involved in bone metabolism, eye development and the immune system. Our findings suggest that a subset of feralisation loci (i.e. genomic targets of recent selection in feral populations) are shared across independently established populations, raising the possibility that feralisation involves some degree of parallelism or convergence and the potential for a shared feralisation 'syndrome'.

RESUMEN

The reliance on vision to control a myoelectric prosthesis is cognitively burdensome and contributes to device abandonment. The feeling of uncertainty when gripping an object is thought to be the cause of this overreliance on vision in hand-related actions. We explored if experimentally reducing grip uncertainty alters the visuomotor control and mental workload experienced during initial prosthesis use. In a repeated measures design, twenty-one able-bodied participants took part in a pouring task across three conditions: (a) using their anatomical hand, (b) using a myoelectric prosthetic hand simulator, and (c) using a myoelectric prosthetic hand simulator with Velcro attached to reduce grip uncertainty. Performance, gaze behaviour (using mobile eye-tracking) and self-reported mental workload, was measured. Results showed that using a prosthesis (with or without Velcro) slowed task performance, impaired typical eye-hand coordination and increased mental workload compared to anatomic hand control. However, when using the prosthesis with Velcro, participants displayed better prosthesis control, more effective eye-hand coordination and reduced mental workload compared to when using the prosthesis without Velcro. These positive results indicate that reducing grip uncertainty could be a useful tool for encouraging more effective prosthesis control strategies in the early stages of prosthetic hand learning.

RESUMEN

INTRODUCTION: Trauma-informed care (TIC) spans many different health care fields and is essential in promoting the well-being and recovery of traumatized individuals. This review aims to assess the efficacy of TIC frameworks in both educating providers and enhancing care for adult and pediatric patients. METHODS: A literature search was conducted using PubMed, EMBASE, Proquest, Cochrane, and Google Scholar to identify relevant articles up to September 28, 2023. Studies implementing TIC frameworks in health care settings as a provider education tool or in patient care were included. Studies were further categorized based on adult or pediatric patient populations and relevant outcomes were extracted. RESULTS: A total of 36 articles were included in this review, evaluating over 7843 providers and patients. When implemented as a provider education tool, TIC frameworks significantly improved provider knowledge, confidence, awareness, and attitudes toward TIC (P < 0.05 to P < 0.001). Trauma screenings and assessments also increased (P < 0.001). When these frameworks were applied in adult patient care, there were positive effects across a multitude of settings, including women's health, intimate partner violence, post-traumatic stress disorder, and inpatient mental health. Findings included reduced depression and anxiety (P < 0.05), increased trauma disclosures (5%-30%), and enhanced mental and physical health (P < 0.001). CONCLUSIONS: This review underscores the multifaceted effectiveness of TIC frameworks, serving both as a valuable educational resource for providers and as a fundamental approach to patient care. Providers reported increased knowledge and comfort with core trauma principles. Patients were also found to derive benefits from these approaches in a variety of settings. These findings demonstrate the extensive applicability of TIC frameworks and highlight the need for a more comprehensive understanding of their applications and long-term effects.

RESUMEN

INTRODUCTION: This narrative review aims to evaluate the efficacy of adjunct direct peritoneal resuscitation (DPR) in the treatment of adult damage control surgery (DCS) patients both with and without hemorrhagic shock, and its impact on associated outcomes. METHODS: PubMed, Google Scholar, EMBASE, ProQuest, and Cochrane were searched for relevant articles published through April 13th, 2023. Studies assessing the utilization of DPR in adult DCS patients were included. Outcomes included time to abdominal closure, intra-abdominal complications, in-hospital mortality, and ICU length of stay (ICU LOS). RESULTS: Five studies evaluating 437 patients were included. In patients with hemorrhagic shock, DPR was associated with reduced time to abdominal closure (DPR 4.1 days, control 5.9 days, p = 0.002), intra-abdominal complications including abscess formation (DPR 27 %, control 47 %, p = 0.04), and ICU LOS (DPR 8 days, control 11 days, p = 0.004). Findings in patients without hemorrhagic shock were conflicting. Closure times were decreased in one study (DPR 5.9 days, control 7.7 days, p < 0.02) and increased in another study (DPR 3.5 days, control 2.5 days, p = 0.02), intra-abdominal complications were decreased in one study (DPR 27 %, control 47 %, p = 0.04) and similar in another, and ICU LOS was decreased in one study (DPR 17 days, control 24 days, p < 0.002) and increased in another (DPR 13 days, control 11.4 days, p = 0.807). CONCLUSION: In patients with hemorrhagic shock, adjunct DPR is associated with reduced time to abdominal closure, intra-abdominal complications such as abscesses, fistula, bleeding, anastomotic leak, and ICU LOS. Utilization of DPR in patients without hemorrhagic shock showed promising but inconsistent findings.

RESUMEN

INTRODUCTION: This narrative review aims to evaluate the impact of current spinal immobilization practices on clinical outcomes in adult trauma patients with suspected or confirmed spinal injury to direct the creation of improved practice management guidelines. METHODS: PubMed, ProQuest, Embase, Google Scholar, and Cochrane were searched for studies that evaluated the impact of spine immobilization practices during resuscitation in adult trauma patients and reported associated clinical outcomes. Outcomes included neurological deficits, in-hospital mortality, hospital length of stay (HLOS), ICU length of stay (ICU-LOS), discharge disposition, long-term functional status (modified Rankin scale), vascular injury rate, and respiratory injury rate. RESULTS: Nine studies were included in this review, divided into two groups based on patient immobilization status. Patients compared with and without cervical immobilization had higher mortality, longer ICU-LOS, and a higher incidence of neurological deficits if immobilized. Immobilization only was associated with a higher incidence of indirect neurological injury and poor functional outcomes. CONCLUSION: Spinal immobilization during resuscitation in adult trauma patients is associated with a higher risk of neurological injury, in-hospital mortality, and longer ICU-LOS. Further research is needed to provide strong evidence for spinal immobilization guidelines and identify the optimal method and timing for immobilization practices in trauma patients.

RESUMEN

BACKGROUND: Patients with liver cirrhosis (LC) demonstrate significantly elevated mortality rates following a traumatic event. This study aims to examine and compare the clinical outcomes in adult trauma patients with pre-existing LC undergoing laparotomy or non-operative management (NOM). Additionally, the study aims to investigate various patient outcomes, including mortality rate based on transfusion needs and timing. METHODS: This retrospective cohort study utilized the American College of Surgeons Trauma Quality Program Participant Use File (ACS-TQIP-PUF) 2017-21 to compare laparotomy vs NOM in adults (≥18 years) with pre-existing LC who presented to trauma facilities with isolated blunt solid organ abdominal injuries (Injury Severity Score ≥16, Abbreviated Injury Scale solid organ abdomen ≥3). RESULTS: Among 929 patients, 38.2% underwent laparotomy, while 61.7% received NOM. The in-hospital mortality rate was lower for patients who received NOM (52.3% vs 20.0%, P < .01). The risk of in-hospital mortality was significantly associated with laparotomy (OR 5.22, 95% CI: 2.06-13.18, P < .01) and sepsis (OR 99.50, 95% CI: 6.99-1415.28, P < .01). On average an increase in blood units in 4 hours was observed among those who experienced an in-hospital mortality (OR 5.65, 95% CI: 3.05-8.24, P < .01) and those who underwent laparotomy (OR 3.85, 95% CI: 1.36-6.34, P < .01). CONCLUSION: Trauma patients with moderate to severe isolated organ injury and Liver cirrhosis had significantly higher mortality rates, acute renal failure, whole blood units received, as well as longer ICU-LOS when undergoing laparotomy compared to non-operative management.

RESUMEN

OBJECTIVES: To examine the distribution of nuchal translucency thickness (NT), free ß-human chorionic gonadotropin (ß-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in pregnancies with a fetal 22q11.2 aberration. Furthermore, the performance of combined first-trimester screening (cFTS) and a new risk algorithm targeting 22q11.2 deletions in detecting affected pregnancies was evaluated. Finally, prenatal malformations and pregnancy outcome were assessed. METHODS: This was a nationwide registry-based cohort study of all pregnancies that underwent prenatal screening with a due date between January 2008 and December 2018 in Denmark. All cases with a fetal 22q11.2 deletion or duplication (hg19 chr22:18.9mio-25.0mio) diagnosed pre- or postnatally or following pregnancy loss or termination of pregnancy were retrieved from the Danish Cytogenetic Central Register and linked with pregnancy data from the Danish Fetal Medicine Database. Fetal and maternal characteristics, including cFTS results and pregnancy outcome, of pregnancies with any 22q11.2 deletion or duplication (LCR22-A to -H) and pregnancies with a classic deletion or duplication (LCR22-A to -D) diagnosed by chromosomal microarray were compared with those of a chromosomally normal reference group. A risk algorithm was developed for assessing patient-specific risks for classic 22q11.2 deletions based on NT, PAPP-A and ß-hCG. Detection rates and false-positive rates at different risk cut-offs were calculated. RESULTS: We included data on 143 pregnancies with a fetal 22q11.2 aberration, of which 97 were deletions (54 classic) and 46 were duplications (32 classic). NT was significantly increased in fetuses with a classic deletion (mean, 1.89 mm), those with any deletion (mean, 1.78 mm) and those with any duplication (mean, 1.86 mm) compared to the reference group (mean, 1.65 mm). ß-hCG multiples of the median (MoM) was decreased in all 22q11.2 subgroups compared with the reference group (mean, 1.02) and reached significance in pregnancies with a classic deletion and those with any deletion (mean, 0.77 and 0.71, respectively). PAPP-A MoM was significantly decreased in pregnancies with a classic duplication and those with any duplication (mean, 0.57 and 0.63, respectively), and was significantly increased in pregnancies with a classic deletion and those with any deletion (mean, 1.34 and 1.16, respectively), compared to reference pregnancies (mean, 1.01). The screen-positive rate by cFTS was significantly increased in pregnancies with a classic deletion (13.7%), any deletion (12.5%), a classic duplication (46.9%) or any duplication (37.8%) compared to the reference group (4.5%). A risk algorithm targeting classic 22q11.2 deletions more than doubled the prenatal detection rate of classic 22q11.2 deletions, but with a substantial increase in the false-positive rate. Structural malformations were detected in 41%, 35%, 17% and 25% of the pregnancies with a classic deletion, any deletion, classic duplication or any duplication, respectively. Pregnancy loss occurred in 40% of pregnancies with a classic deletion and 5% of those with a classic duplication diagnosed prenatally or following pregnancy loss. CONCLUSIONS: The distribution of cFTS markers in pregnancies with a classic 22q11.2 duplication resembles that of the common trisomies, with decreased levels of PAPP-A. However, classic 22q11.2 deletions are associated with increased levels of PAPP-A, which likely limits early prenatal detection using the current cFTS risk algorithm. The scope for improving early detection of classic 22q11.2 deletions using targeted risk algorithms based on NT, PAPP-A and ß-hCG is limited. This demonstrates the capability, but also the limitations, of cFTS markers in detecting atypical chromosomal anomalies, which is important knowledge when designing new prenatal screening programs. © 2023 The Authors.

RESUMEN

OBJECTIVES: To describe the distributional properties and assess the performance of placental growth factor (PlGF) measured in blood samples collected before 11 weeks' gestation in the prediction of pre-eclampsia (PE). METHODS: The study population consisted of pregnant women included in the Pre-eclampsia Screening in Denmark (PRESIDE) study with a PlGF measurement from the routine combined first-trimester screening (cFTS) blood sample collected at 8-14 weeks' gestation. PRESIDE was a prospective multicenter study investigating the predictive performance of the Fetal Medicine Foundation (FMF) first-trimester screening algorithm for PE in a Danish population. In the current study, serum concentration of PlGF in the cFTS blood samples was analyzed in batches between January and June 2021. RESULTS: A total of 8386 pregnant women were included. The incidence of PE was 0.7% at < 37 weeks' gestation and 3.0% at ≥ 37 weeks. In blood samples collected at 10 weeks' gestation, PlGF multiples of the median (MoM) were significantly lower in pregnancies with preterm PE < 37 weeks compared to unaffected pregnancies. However, PlGF MoM did not differ significantly between pregnancies with PE and unaffected pregnancies in samples collected before 10 weeks' gestation. CONCLUSIONS: The gestational-age range for PlGF sampling may be expanded from 11-14 to 10-14 weeks when assessing the risk for PE using the FMF first-trimester screening model. There is little evidence to support the use of PlGF in blood samples collected before 10 weeks' gestation. © 2023 The Authors.

RESUMEN

INTRODUCTION: Disparities in venous thromboembolism (VTE) incidence and prophylaxis have been observed across racial groups. This study investigates the relationship between race, injury type, and the timing of VTE prophylaxis in severe trauma patients, both with and without isolated traumatic brain injuries. The primary goal is to analyze how these factors interact and their potential impact on clinical outcomes. METHODS: A retrospective cohort study of the American College of Surgeons Trauma Quality Program Participant Use File (ACS-TQIP-PUF) from 2018 to 2021. Patient demographics, injury categories, VTE prophylaxis timing, injury severity, and in-hospital complications were collected. Multivariable regression models explored associations between race, injury type, VTE prophylaxis, and in-hospital mortality. Groups were analyzed by injury profile (isolated TBI vs non-TBI) and then by VTE prophylaxis timing (early ≤24 hours, late >24 hours). RESULTS: Of 68,504 trauma patients analyzed, the majority were non-Hispanic or Latino (83.3%), White (71.2%), and male (69.6%). Patients receiving late VTE prophylaxis had higher rates of DVT and PE across race groups than patients with early prophylaxis. Logistic regression showed Asian patients with TBI receiving early prophylaxis were significantly more likely to have in-hospital mortality (OR 16.27, CI = 1.11-237.43, P = .04) than other races. CONCLUSION: Patients who received late prophylaxis had higher VTE rates than early prophylaxis, independent of injury pattern or race. Additionally, assessing the implications of race in early VTE prophylaxis for isolated TBI showed that adult Asian patients had 16 times higher odds of in-hospital mortality compared to other races.

RESUMEN

BACKGROUND: This systematic review aims to evaluate and compare differences in clinical outcomes for adult patients diagnosed with ISSPE who were managed with anticoagulation vs clinical surveillance. METHODS: PubMed, Embase, ProQuest, Cochrane, and Google Scholar were searched to identify studies evaluating the use of anticoagulation and/or clinical surveillance in patients diagnosed with ISSPE. The search included studies published up to August 3, 2023. Outcomes of interest included 90-day recurrent venous thromboembolism (VTE), major bleeding, and all-cause mortality rates. RESULTS: Ten studies were included with a total of 1224 patients. Of these patients, 791 were treated with anticoagulation and 433 underwent surveillance. Studies found no difference in recurrent VTE rates, with the majority of studies reporting no recurrence. Of the studies that reported VTE recurrence, rates were .5% to 1.4% for the anticoagulation groups and 3.1% to 3.2% for the surveillance groups. Major bleeding rates were also similar. In anticoagulated patients, major bleeding rates ranged from 1% to 10%. In clinical surveillance patients, the majority found no rate of major bleeding, with 2 studies reporting rates of .8% to 3.2%. Mortality rates ranged widely with no significant differences reported. CONCLUSION: Clinical surveillance appears to be a safe and effective alternative to anticoagulation in patients with ISSPE. Ninety-day rates of recurrent VTE, major bleeding, and mortality were comparable between groups. These findings highlight the need for updated practice management guidelines to improve patient outcomes.

RESUMEN

OBJECTIVE: To derive reference distributions of estimated fetal weight (EFW) in twins relative to singletons. METHODS: Gestational-age- and chorionicity-specific reference distributions for singleton percentiles and EFW were fitted to data on 4391 twin pregnancies with two liveborn fetuses from four European centers, including 3323 dichorionic (DC) and 1068 monochorionic diamniotic (MCDA) twin pregnancies. Gestational age was derived using the larger of the two crown-rump length measurements obtained during the first trimester of pregnancy. EFW was obtained from ultrasound measurements of head circumference, abdominal circumference and femur length using the Hadlock formula. Singleton percentiles were obtained using the Fetal Medicine Foundation population weight charts for singleton pregnancies. Hierarchical models were fitted to singleton Z-scores with autoregressive terms for serial correlations within the same fetus and between twins from the same pregnancy. Separate models were fitted for DC and MCDA twins. RESULTS: Fetuses from twin pregnancies tended to be smaller than singletons at the earliest gestational ages (16 weeks for MCDA and 20 weeks for DC twins). This was followed by a period of catch-up growth until around 24 weeks. After that, both DC and MCDA twins showed reduced growth. In DC twins, the EFW corresponding to the 50th percentile was at the 50th percentile of singleton pregnancies at 23 weeks, the 43rd percentile at 28 weeks, the 32nd percentile at 32 weeks and the 22nd percentile at 36 weeks. In MCDA twins, the EFW corresponding to the 50th percentile was at the 36th percentile of singleton pregnancies at 24 weeks, the 29th percentile at 28 weeks, the 19th percentile at 32 weeks and the 12th percentile at 36 weeks. CONCLUSIONS: In DC and, to a greater extent, MCDA twin pregnancies, fetal growth is reduced compared with that observed in singleton pregnancies. Furthermore, after 24 weeks, the divergence in growth trajectories between twin and singleton pregnancies becomes more pronounced as gestational age increases. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

RESUMEN

OBJECTIVE: To compare morbidity, as measured by length of stay in the neonatal intensive care unit (NICU), in twin and singleton gestations classified as small-for-gestational age (SGA) according to estimated fetal weight < 10th percentile on twin or singleton growth charts. METHODS: NICU length of stay was compared in 1150 twins and 29 035 singletons that underwent ultrasound assessment between 35 + 0 and 36 + 6 weeks' gestation. Estimated fetal weight was obtained from measurements of head circumference, abdominal circumference and femur length using the Hadlock formula. Gestational age was derived from the first-trimester crown-rump length measurement, using the larger of the two twins. Singletons and twins were compared in terms of NICU admission rate and length of stay according to classification as SGA by the Fetal Medicine Foundation singleton and twin reference distributions. RESULTS: The overall proportions of twins and singletons admitted to NICU were similar (7.3% vs 7.4%), but twins tended to have longer lengths of stay in NICU (≥ 7 days: 2.4% vs 0.8%; relative risk (RR), 3.0 (95% CI, 1.6-4.4)). Using the singleton chart, a higher proportion of twins were classified as SGA compared with singletons (37.6% vs 7.0%). However, the proportion of SGA neonates entering NICU was similar (10.2% for twins and 10.1% for singletons) and the proportion of SGA neonates spending ≥ 7 days in NICU was substantially higher for twins compared with singletons (3.7% vs 1.4%; RR, 2.6 (95% CI, 1.4-4.7)). CONCLUSIONS: When singleton charts are used to define SGA in twins and in singletons, there is a greater degree of growth-related neonatal morbidity amongst SGA twins compared with SGA singletons. Consequently, singleton charts do not inappropriately overdiagnose fetal growth restriction in twins and they should be used for monitoring fetal growth in both twins and singletons. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.
