RESUMEN
OBJECTIVE: To examine health-related quality of life (HRQL) and satisfaction with appearance in patients who have undergone bariatric surgery (BS) with or without subsequent body contouring surgery (BCS) in relation to the general population normative for the BODY-Q. BACKGROUND: The long-term impact of BS with or without BCS has not been established using rigorously developed and validated patient-reported outcome measures. The BODY-Q is a patient-reported outcome measure developed to measure changes in HRQL and satisfaction with appearance in patients with BS and BCS. METHODS: Prospective BODY-Q data were collected from 6 European countries (Denmark, the Netherlands, Finland, Germany, Italy, and Poland) from June 2015 to February 2022 in a cohort of patients who underwent BS. Mixed-effects regression models were used to analyze changes in HRQL and appearance over time between patients who did and did not receive BCS and to examine the impact of patient-level covariates on outcomes. RESULTS: This study included 24,604 assessments from 5620 patients. BS initially led to improved HRQL and appearance scores throughout the first postbariatric year, followed by a gradual decrease. Patients who underwent subsequent BCS after BS experienced a sustained improvement in HRQL and appearance or remained relatively stable for up to 10 years postoperatively. CONCLUSIONS: Patients who underwent BCS maintained an improvement in HRQL and satisfaction with appearance in contrast to patients who only underwent BS, who reported a decline in scores 1 to 2 years postoperatively. Our results emphasize the pivotal role that BCS plays in the completion of the weight loss trajectory.

OBJECTIVES: After cleft lip and/or palate (CL/P) repair, children may develop velopharyngeal insufficiency (VPI) leading to speech imperfections, necessitating additional speech correcting surgery. This study examines the incidence of VPI and speech correcting surgery after Sommerlad's palatoplasty for CL/P, and its association with various clinical features. MATERIALS AND METHODS: A retrospective cohort study was performed in the Wilhelmina Children's Hospital in Utrecht and child records from 380 individuals with CL/P registered from 2008 to 2017 were retrospectively reviewed. Inclusion criteria comprised the diagnosis of CL/P, primary palatoplasty according to Sommerlad's technique, and speech assessment at five years or older. Association between cleft type and width, presence of additional genetic disorders and postoperative complications (palatal dehiscence, fistula) were assessed using odds ratios and chi squared tests. RESULTS: A total of 239 patients were included. The VPI rate was 52.7% (n = 126) and in 119 patients (49.8%) a speech correcting surgery was performed. Severe cleft type, as indicated by a higher Veau classification, was associated with a significant higher rate of speech correcting surgeries (p = 0.033). Significantly more speech correcting surgeries were performed in patients with a cleft width >10 mm, compared to patients with a cleft width ≤10 mm (p < 0.001). Patients with oronasal fistula underwent significantly more speech correcting surgeries than those without fistula (p = 0.004). No statistically significant difference was found in the incidence of speech correcting surgery between patients with and without genetic disorders (p = 0.890). CONCLUSIONS/CLINICAL RELEVANCE: Variations in cleft morphology, cleft width and complications like oronasal fistula are associated with different speech outcomes. Future research should focus on creating a multivariable prediction model for speech correcting surgery in CL/P patients.

The European Reference Network for Rare Craniofacial Aanomalies and Ear-Nose-Throat disorders aims to improve care for patients with such afflictions, including cleft lip and palate (CL/P) across Europe. Cleft treatment remains varied throughout European centers, inhibiting meaningful comparison of treatment outcomes. To overcome these issues, a European-wide common CL/P dataset and registry was developed, facilitating standardized treatment endpoints and outcome measures for international comparison and benchmarking of CL/P centers. Questionnaires and semi-structured interviews were used to determine the set-up of the registry. Previous CL/P initiatives were analyzed to create an initial dataset, refined through consensus meetings. In total, 87 cleft specialists working in specialized CL/P centers from 16 European nations participated. Consensus on a common dataset was reached. A "Level 1" dataset, with mandatory clinical and patient-reported outcome measures, and "Level 2" dataset with additional outcome measures. Finally, 2 dashboards were developed for data dissemination. The development of the European CL/P common dataset and registry tackled challenges with resource disparities, variations in specialists within CL/P teams, regulatory differences in patient data usage, patient-reported outcome measures availability in European languages, and use of assessment tools. This study described the successful development of the European Reference Network for Rare Craniofacial Aanomalies and Ear-Nose-Throat disorders CL/P common dataset and registry. This achievement will help improve patient care and outcomes for patients with CL/P in Europe. Furthermore, this study provides useful information for initiatives with similar aims.
RESUMEN
OBJECTIVE/DESIGN/SETTING: This retrospective study sought voluntary participation from leading cleft centres from Europe and Brazil regarding core outcome measures. The results of this study would inform the debate on core outcome consensus pertaining to the European Reference Network for rare diseases (ERN CRANIO) and achieve a core outcome set for cleft care providers worldwide. INTERVENTION/METHOD: Five orofacial cleft (OFC) disciplines were identified, within which all of the International Consortium of Health Outcomes Measurement (ICHOM) outcomes fall. One questionnaire was designed for each discipline and comprised 1. the relevant ICHOM's outcomes within that discipline, and 2. a series of questions targeted to clinicians. What core outcomes are currently measured and when, did these align with the ICHOM minimum, if not how did they differ, and would they recommend modified or additional outcomes?. RESULTS: For some disciplines participants agreed with the ICHOM minimums but urged for earlier and more frequent intervention. Some clinicians felt that some of the ICHOM standards were compatible but that different ages were preferred and for others the ICHOM standards were acceptable but developmental stages should be preferred to absolute time points. CONCLUSION/IMPLICATIONS: Core outcomes for OFC were supported in principle but there are differences between the ICHOM recommendations and the 2002 WHO global consensus. The latter are established in many centres with historical archives of OFC outcome data, and it was concluded that with some modifications ICHOM could be moulded into useful core outcomes data for inter-centre comparisons worldwide.

BACKGROUND: The BODY-Q is a patient-reported outcome measure developed for use in bariatric and body contouring surgery. OBJECTIVES: The objective of this study was to examine the validity and reliability of the Dutch version of the BODY-Q. METHODS: The BODY-Q consists of 163 items in 21 independently functioning scales that measure appearance, health-related quality of life, and experience of care. The data used to validate the Dutch BODY-Q were provided by 2 prospective multicenter cohort studies across 3 hospitals in the Netherlands. The BODY-Q was administered before and after surgery at 3 or 4 months and 12 months. Rasch measurement theory (RMT) analysis was used to evaluate the BODY-Q for targeting, category threshold order, Rasch model fit, Person Separation Index, and differential item functioning by language (original English data vs Dutch data). RESULTS: Data were collected between January 2016 and May 2019. The study included 876 participants, who provided 1614 assessments. Validity was supported by 3 RMT findings: most scales showed good targeting, 160 out of 163 items (98.2%) evidenced ordered thresholds, and 142 out of 163 items (87.1%) fitted the RMT model. Reliability was high with Person Separation Index values >0.70 for 19 out of 21 scales. There was negligible influence of differential item functioning by language on person item locations and the scale scoring. CONCLUSIONS: This study provides evidence for the reliability and validity of the Dutch BODY-Q for use in bariatric and body contouring patients in the Netherlands. The Dutch BODY-Q can be used in (inter)national research and clinical practice.

PURPOSE: Operative treatment of trapeziometacarpal osteoarthritis (TMC OA) is discretionary. There is substantial surgeon-to-surgeon variation in offers of surgery. This study assessed factors associated with variation in recommendation of operative treatment to patients with TMC OA. Secondarily, we studied factors associated with preferred operative technique and surgeon demographic factors variability in recommendation for operative treatment. METHODS: We invited all hand surgeon members of the Science of Variation Group to review 16 scenarios of patients with TMC OA and asked the surgeons whether they would recommend surgical treatment for each patient and, if yes, which surgical technique they would offer (trapeziectomy, trapeziectomy with ligament reconstruction and/or tendon interposition, joint replacement, or arthrodesis). Scenarios varied in pain intensity, relief after injection, radiographic severity, and psychosocial symptoms. RESULTS: Patient characteristics associated with greater likelihood to recommend surgical treatment were substantial pain, a previous injection that did not relieve pain, radiograph with severe TMC OA, and few symptoms of depression. Practice region was the only factor associated with preferred surgical technique and trapeziectomy with ligament reconstruction and/or tendon interposition the most commonly recommended treatment. There was low agreement among surgeons regarding treatment recommendations. CONCLUSIONS: The notable variation in offers of operative treatment for TMC OA is largely associated with variable attention to subjective factors. Future studies might address the relative influence of surgeon incentives and beliefs, objective pathophysiology, and subjective patient factors on variation in surgeon recommendations. CLINICAL RELEVANCE: Surgeons' awareness of the potential influence of subjective factors on their recommendations might contribute to efforts to ensure that patient choices reflect what matters most to them and are not based on misconceptions.

OBJECTIVE: Long-term outcomes of patients born with a cleft lip and palate (CLP) are scarcely investigated. Yet, this patient group is of particular interest, as they can provide a valuable retrospective view upon their treatment experiences and psychological adjustment. Qualitative accounts may be especially useful in understanding the patient journey. DESIGN: The present study set out to evaluate quality of life and satisfaction with treatment in adult patients previously treated for CLP at the Wilhelmina Children's Hospital. Semistructured interviews were performed. PATIENTS: A total of 22 patients aged 17 to 35 years (mean: 25 years) were interviewed about their experiences of growing up with CLP and of the treatment they received. Interviews were audio-recorded and factors thought to influence psychological adjustment were identified. RESULTS: Four main themes were identified: background factors, support systems, treatment factors, and coping/internal factors. Each theme was described with illustrative quotes. CONCLUSION: This study underlines that psychological adjustment can fluctuate over time and greatly differs between individuals, even during adulthood. Psychological support should therefore be available beyond the finalization of the treatment course. Furthermore, the majority of participants stated they had wanted more psychological support as a child to facilitate resilience and to help them cope with challenges.

Although Robin sequence (RS) is a well-known phenomenon, it is still associated with considerable morbidity and even mortality. The purposes of this study were to gain greater insight into the mortality rate and identify risk factors associated with mortality in RS. We retrospectively reviewed all RS infants followed at the Wilhelmina Children's Hospital from 1995 to 2016. Outcome measurements were death and causes of death. The authors identified 103 consecutive RS infants with a median follow-up of 8.6 years (range 0.1-21.9 years). Ten of the 103 infants (10%) died at a median age of 0.8 years (range 0.1-5.9 years). Nine of these ten infants (90%) were diagnosed with an associated syndrome. Of these, seven infants died of respiratory insufficiency due to various causes (two related to upper airway obstruction). The other two syndromic RS infants died of arrhythmia due to hypernatremia and of West syndrome with status epilepticus. One isolated RS infant died of brain ischemia after MDO surgery. Cardiac anomalies were observed in 41% and neurological anomalies in 36%. The presence of a neurological anomaly was associated with a mortality rate of 40% versus 7% in infants with no neurological anomaly (p = 0.016), with an odds ratio of 8.3 (95% CI 1.4-49.0) for neurological anomaly versus no neurological anomaly. Mortality was 15% in infants with syndromic RS versus 2% in infants with isolated RS (p = 0.044). Mortality was not significantly associated with the presence of a cardiac anomaly, surgical treatment for severe respiratory distress in the neonatal period, or prematurity. CONCLUSION: RS represents a heterogeneous patient population and is associated with a high level of underlying syndromes. The present study reports a mortality rate of 10% significantly associated with syndromic RS and the presence of neurological anomalies. A multidisciplinary approach in all infants born with RS, including genetic testing and examination of neurological anomalies in a standardized way, is crucial to identify infants with underlying syndromes potentially associated with increased mortality. What is Known: ⢠Reported mortality rates in Robin sequence vary from 2% to 26%. ⢠Clinicians mainly focus on the morbidity of Robin sequence that includes respiratory complications due to upper airway obstruction in the period after birth. ⢠Robin sequence represents a heterogeneous patient population and is associated with a high level of underlying syndromes. What is New: ⢠The present study reports a mortality rate of 10% significantly associated with syndromic Robin sequence and the presence of neurological anomalies. ⢠A multidisciplinary approach in all infants born with Robin sequence, including genetic evaluation and standardized workup for neurological anomalies, is crucial to identify infants with underlying syndromes potentially associated with increased mortality.

The Dutch cleft speech evaluation test (DCSET) has been implemented by the speech-language pathologists nationwide in the Netherlands since 2003, but the inter- and intrarater reliability was unknown. Two speech-language pathologists experienced in evaluating cleft speech assessed audio recordings of 20 children with cleft speech using the DCSET, and reassessed the recordings 2 weeks later. Intra- and interrater reliability was calculated, but found to be unacceptable after the first phase of this study using audio recordings. Following consensus training and some modifications in the scoring scales, the study was repeated using video recordings of 20 different children with cleft speech. Results from the second phase of this study using standardized video recordings showed fair, moderate, and good reliability on different subsets of the DCSET. Intrarater reliability (Kappa 0.59-1.00) was greater than interrater reliability (Kappa 0.33-0.79). Interrater reliability agreement was good (Kappa 0.63-0.79) for consonant production errors and speech understandability and acceptability, moderate (Kappa 0.59) for the resonance of the nasal passage, and fair (Kappa 0.33-0.37) for the resonance of the mixed and denasal passages. Subsequently, an algorithm was made to convert the DCSET scales to universal scales for international comparison of cleft speech as suggested by Henningsson et al in 2008.

OBJECTIVES: The prenatal diagnosis of oral clefts (OCs) by ultrasound can pose an ethical dilemma. The purpose of this study was to obtain insight into the psychosocial and moral considerations of prospective parents concerning OCs, the burden of OCs and parents' attitude toward possible termination of pregnancy (TOP) in order to improve counseling in the future. DESIGN: Between August 2011 and August 2014, a prospective cohort questionnaire study was administered. SETTING: Prenatal care clinic of the Wilhelmina's Children hospital, a Tertiary Care Centre. PARTICIPANTS: Parents expecting a child with an OC. MAIN OUTCOME MEASURES: Expectation of OCs in general and attitudes toward the impact and expected burden of the OC of their child. Furthermore, parents were asked if they had considered TOP. RESULTS: Most of the parents described an OC as a cosmetic disability (50.6%) or as "just a little different" (29.4%). These parents expected that the OC would not affect their own happiness and have only minor influence on the happiness of their future child. Health professionals had a considerable influence on parental opinion. A minority (6.4%, 5/85) of the respondents considered TOP, and none of the responders chose to terminate the pregnancy. CONCLUSIONS: This study suggests that future parents have very few negative perceptions of OC after prenatal counseling. Caregivers should be aware that their counseling is important for decision-making of parents.
RESUMEN
The purpose of this study was to examine extracellular matrix composition, vascularization, and immune cell population of skin sites prone to keloid formation. Keloids remain a complex problem, posing esthetical as well as functional difficulties for those affected. These scars tend to develop at anatomic sites of preference. Mechanical properties of skin vary with anatomic location and depend largely on extracellular matrix composition. These differences in extracellular matrix composition, but also vascularization and resident immune cell populations might play a role in the mechanism of keloid formation. To examine this hypothesis, skin samples of several anatomic locations were taken from 24 human donors within zero to 36 hours after they had deceased. Collagen content and cross-links were determined through high-performance liquid chromatography. The expression of several genes, involved in extracellular matrix production and degradation, was measured by means of real-time PCR. (Immuno)histochemistry was performed to detect fibroblasts, collagen, elastin, blood vessels, Langerhans cells, and macrophages. Properties of skin of keloid predilections sites were compared to properties of skin from other locations (nonpredilection sites [NPS]). The results indicated that there are site specific variations in extracellular matrix properties (collagen and cross-links) as well as macrophage numbers. Moreover, predilection sites (PS) for keloid formation contain larger amounts of collagen compared to NPS, but decreased numbers of macrophages, in particular classically activated CD40 positive macrophages. In conclusion, the altered (histological, protein, and genetic) properties of skin of keloid PS may cause a predisposition for and contribute to keloid formation.

This study aimed to examine changes in the inflammatory response in early hypertrophic compared to normal wound healing. The immune system is thought to be involved in hypertrophic scar formation. However, the exact mechanism and time of onset of the derailment remain unknown. In a prospective observational study, skin biopsies were taken directly postwounding and 3 hours later from patients who had elective cardiothoracic surgery. The skin biopsies were analysed for mRNA, proteins and cells involved in the early inflammatory phase of wound healing. The endpoint was scar outcome (hypertrophic (HTS) or normal (NTS)) at one year after surgery. There were significant differences between the NTS and HTS groups regarding the fold changes of mRNA expression of P-selectin during surgery. Postoperative skin concentrations of inflammatory proteins IL-6, IL-8 and CCL2 were significantly lower in the HTS compared to the NTS group. Also, a trend of higher pre-operative M2 macrophage numbers was observed in the HTS group. Neutrophil numbers increased equally during surgery in both groups. The increase of P-selectin mRNA in hypertrophic wound healing could affect leucocyte migration. The decreased concentrations of inflammatory proteins in hypertrophic wound healing indicate a reduced inflammatory response, which has consequences for the treatment of hypertrophic scarring during the early inflammatory phase. In a conclusion, alterations of wound healing associated with hypertrophic scarring are visible as early as 3 hours postwounding and include a reduced rather than increased inflammatory protein response.

BACKGROUND: Traditional open corrective surgery for isolated sagittal synostosis entails significant blood loss, transfusion rates, morbidity, and a lengthy hospitalization. Minimally invasive strip craniectomy (MISC) was introduced to avoid the disadvantages of open techniques. OBJECTIVES: The aim of the study was, first, to compare the anesthesia practice in MISC and open extended strip craniectomy (OESC), and, second, to evaluate the incidence of perioperative complications in both surgical procedures. METHODS: A retrospective analysis was conducted for all consecutive patients receiving either OESC or MISC for nonsyndromic isolated sagittal synostosis between January 2006 and February 2014. The primary endpoints were the volume of blood loss, the volume of infused blood products, the duration of surgery, the anesthesia time, the intubation time, and the length of admission to high care units and the hospital. RESULTS: In MISC, the median duration of surgery (90 versus 178âmin.), anesthesia time (178 versus 291âmin), and intubation time (153 versus 294âmin) were all significantly (Pâ<â0.001) shorter than in OESC. Intraoperative blood loss was less in MISC than in OESC (3.8 versus 29.7âmL/kg, Pâ<â0.001), requiring less crystalloids (33.3 versus 76.9âmL/kg, Pâ<â0.001) as well as less erythrocyte transfusions (0.0 versus 19.7âmL/kg, Pâ<â0.001) in a smaller number of patients (2/20 versus 13/15). The improved hemodynamic stability in MISC allowed for placement of less arterial and central venous catheters. After OESC all 15 patients were admitted to high care units, compared with 9 of 20 in MISC. The overall median hospital stay was shorter in MISC than in OESC (4 versus 6 d, Pâ<â0.001). Although the incidence of technical complications was similar in both techniques, patients in MISC were less affected by perioperative electrolyte and acid-base disturbances and postoperative pyrexia. CONCLUSIONS: Minimally invasive strip craniectomy simplifies anesthesia practice relative to OESC with shorter operative times, decreased needs for replacement fluids and blood products, lessened requirements for invasive monitoring, and reduced demands for postoperative high care beds.

The aim of this study was to examine the association between possible risk factors for excessive scarring and the formation of hypertrophic scars (HTS). Hypertrophic skin scarring remains a difficult problem in medicine and can cause considerable morbidity. Nevertheless, few extensive prospective studies have been conducted which assess risk factors in relation to HTS formation. Therefore, a prospective observational study was performed. Patients who had elective cardiothoracic surgery were followed for the duration of 1 year and information was collected about a variety of possible risk factors in these patients. The associations between the risk factors and the development of HTSs were investigated. Body mass index, ethnic background, and scar related factors are positively associated with HTS formation. Antihypertensive therapeutics and factors influencing erythropoiesis are negatively associated with HTS formation.

OBJECTIVE: Our aim is to introduce and validate a new oral cleft classification system based on prenatal ultrasound for use by professionals in daily practice. METHODS: During a 3-year period (2011-2014), all cases of prenatal oral cleft diagnosed by ultrasound were retrospectively reviewed. A new prenatal ultrasound classification system was introduced. For the purpose of validation, prenatal ultrasound images of oral cleft types were described according to the new classification system and were compared with postnatal findings by reviewing medical records. RESULTS: A total of 103 fetuses with oral cleft were identified by ultrasound. The mean gestation time at detection was 20.4 weeks (95% confidence intervals: 20.0-20.7). The association between oral cleft and other anomalies varied by cleft type; types 2b/3b and 4 were most frequently associated with other anomalies. The measure of agreement between the prenatal and postnatal findings showed a Kappa value of 0.63 (95% confidence intervals: 0.52-0.75), demonstrating the accuracy of this new classification system. CONCLUSION: A new prenatal oral cleft classification system is presented. This system appears to be accurate, and it shows the variation in the risk of associated anomalies for each cleft type. We expect that ultrasonographers will be able to use the new classification in daily practice.

OBJECTIVE: The aim of this study was to assess the opinion of obstetric care providers who perform prenatal ultrasounds to screen for anomalies and who advise women about their options, including termination of pregnancy, when an oral cleft is detected. We compared providers' opinions about pregnancy termination for isolated oral cleft in The Netherlands, where the number of terminations is low, and in Israel, where the number is high. METHODS: Online questionnaires were used. The questions assessed the providers' views regarding the estimated burden of treatment, the functioning ability, and the level of happiness of children with an oral cleft and their parents. Additionally, we assessed providers' opinions on pregnancy termination for isolated oral cleft. RESULTS: In The Netherlands, more professionals considered oral cleft a disability (rate differences 17.8%, 95% confidence interval: 0.5-33.1%) than in Israel. In the Netherlands, 10.6% of respondents (compared with 11.1% in Israel) thought that an isolated cleft was a reason for terminations of pregnancy (TOP) (rate differences 0.6%, 95% confidence interval: -12% to 10.9%). CONCLUSIONS: Prenatal care providers in The Netherlands and Israel do not differ in their opinions about the severity of oral cleft and the acceptability of TOP for an isolated oral cleft. This study shows that prenatal care providers' attitudes do therefore not explain the dramatic difference between these countries in the number of TOP for isolated oral cleft.

OBJECTIVES: Initial approaches to and treatments of infants with Robin sequence (RS) is diverse and inconsistent. The care of these sometimes critically ill infants involves many different medical specialties, which can make the decision process complex and difficult. To optimize the care of infants with RS, we present our institution's approach and a review of the current literature. MATERIAL AND METHODS: A retrospective cohort study was conducted among 75 infants diagnosed with RS and managed at our institution in the 1996-2012 period. Additionally, the conducted treatment regimen in this paper was discussed with recent literature describing the approach of infants with RS. RESULTS: Forty-four infants (59%) were found to have been treated conservatively. A significant larger proportion of nonisolated RS infants than isolated RS infants needed surgical intervention (53 vs. 25%, p = .014). A mandibular distraction was conducted in 24% (n = 18) of cases, a tracheotomy in 9% (n = 7), and a tongue-lip adhesion in 8% (n = 6). Seventy-seven percent of all infants had received temporary nasogastric tube feeding. The literature review of 31 studies showed that initial examinations and the indications to perform a surgical intervention varied and were often not clearly described. CONCLUSIONS: RS is a heterogenic group with a wide spectrum of associated anomalies. As a result, the decisional process is challenging, and a multidisciplinary approach to treatment is desirable. Current treatment options in literature vary, and a more uniform approach is recommended. CLINICAL RELEVANCE: We provide a comprehensive and pragmatic approach to the analysis and treatment of infants with RS, which could serve as useful guidance in other clinics.

Vascularized composite allografts (VCAs) present unique challenges in transplant medicine, owing to their complex structure and vulnerability to ischemic injury. Innovative preservation techniques are crucial for extending the viability of these grafts, from procurement to transplantation. This study addresses these challenges by integrating cryoprotectant agent (CPA) optimization, advanced thermal tracking, and stepwise CPA loading strategies within an ex vivo rodent model. CPA optimization focused on various combinations, identifying those that effectively suppress ice nucleation while mitigating cytotoxicity. Thermal dynamics were monitored using invasive thermocouples and non-invasive FLIR imaging, yielding detailed temperature profiles crucial for managing warm ischemia time and optimizing cooling rates. The efficacy of stepwise CPA loading versus conventional flush protocols demonstrated that stepwise (un)loading significantly improved arterial resistance and weight change outcomes. In summary, this study presents comprehensive advancements in VCA preservation strategies, combining CPA optimization, precise thermal monitoring, and stepwise loading techniques. These findings hold potential implications for refining transplantation protocols and improving graft viability in VCA transplantation.
RESUMEN
Vascularized composite allotransplantations are complex procedures with substantial functional impact on patients. Extended preservation of VCAs is of major importance in advancing this field. It would result in improved donor-recipient matching as well as the potential for ex vivo manipulation with gene and cell therapies. Moreover, it would make logistically feasible immune tolerance induction protocols through mixed chimerism. Supercooling techniques have shown promising results in multi-day liver preservation. It consists of reaching sub-zero temperatures while preventing ice formation within the graft by using various cryoprotective agents. By drastically decreasing the cell metabolism and need for oxygen and nutrients, supercooling allows extended preservation and recovery with lower ischemia-reperfusion injuries. This study is the first to demonstrate the supercooling of a large animal model of VCA. Porcine hindlimbs underwent 48 h of preservation at - 5 °C followed by recovery and normothermic machine perfusion assessment, with no issues in ice formation and favorable levels of injury markers. Our findings provide valuable preliminary results, suggesting a promising future for extended VCA preservation.

BACKGROUND: Warm ischemia time (WIT) and ischemia-reperfusion injury are limiting factors for vascularized composite allograft (VCA) transplantation. Subnormothermic machine perfusion (SNMP) has demonstrated the potential to extend WIT in organ transplantation. This study evaluates the effect of SNMP on VCA viability after prolonged WIT. METHODS: Rat hindlimbs underwent WIT for 30, 45, 60, 120, 150, or 210 min, followed by 3-h SNMP. Monitoring of perfusion parameters and outflow determined the maximum WIT compatible with limb viability after SNMP. Thereafter, 2 groups were assessed: a control group with inbred transplantation (Txp) after 120 min of WIT and an experimental group that underwent WIT + SNMP + Txp. Graft appearance, blood gas, cytokine levels, and histology were assessed for 21 d. RESULTS: Based on potassium levels, the limit of WIT compatible with limb viability after SNMP is 120 min. Before this limit, SNMP reduces potassium and lactate levels of WIT grafts to the same level as fresh grafts. In vivo, the control group presented 80% graft necrosis, whereas the experimental group showed no necrosis, had better healing (Pâ =â 0.0004), and reduced histological muscle injury (Pâ =â 0.012). Results of blood analysis revealed lower lactate, potassium levels, and calcium levels (Pâ =â 0.048) in the experimental group. Both groups presented an increase in interleukin (IL)-10 and IL-1b/IL-1F2 with a return to baseline after 7 to 14 d. CONCLUSIONS: Our study establishes the limit of WIT compatible with VCA viability and demonstrates the effectiveness of SNMP in restoring a graft after WIT ex vivo and in vivo, locally and systemically.
