Age assessment in unaccompanied minors: assessing uniformity of protocols across Europe.

Age assessment of migrants is crucial, particularly for unaccompanied foreign minors, a population facing legal, social, and humanitarian challenges. Despite existing guidelines, there is no unified protocol in Europe for age assessment.The Forensic Anthropology Society of Europe (FASE) conducted a comprehensive questionnaire to understand age estimation practices in Europe. The questionnaire had sections focusing on the professional background of respondents, annual assessment numbers, requesting parties and reasons, types of examinations conducted (e.g., physical, radiological), followed protocols, age estimation methods, and questions on how age estimates are reported.The questionnaire's findings reveal extensive engagement of the forensic community in age assessment in the living, emphasizing multidisciplinary approaches. However, there seems to be an incomplete appreciation of AGFAD guidelines. Commonalities exist in examination methodologies and imaging tests. However, discrepancies emerged among respondents regarding sexual maturity assessment and reporting assessment results. Given the increasing importance of age assessment, especially for migrant child protection, the study stresses the need for a unified protocol across European countries. This can only be achieved if EU Member States wholeheartedly embrace the fundamental principles outlined in EU Directives and conduct medical age assessments aligned with recognized standards such as the AGFAD guidelines.

A taskforce for national improvement of innovation implementation in radiotherapy.

BACKGROUND AND PURPOSE: Previous research among Dutch radiotherapy centres (RTCs) showed that 69% of innovations was simultaneously implemented in 7/19 centres, with a success rate of 51%. However, no structure to share lessons learned about the implementation process existed. Therefore, a national Taskforce Implementation (TTI) was raised to stimulate efficient implementation of innovations. The aim of the current study was to develop and pilot-evaluate a website for facilitating mutual learning on implementation issues. MATERIAL AND METHODS: First, we made an inventory in all Dutch RTCs on their 10 most valuable innovations between 2019 and 2022. In-depth interviews, structured according to the Consolidated Framework for Implementation Research, were performed on the four most mentioned topics. A website was built, and pilot evaluated 1 year after the launch, using a qualitative survey amongst the TTI members. RESULTS: In 13/18 centres, 19 interviews were conducted on 1) automation, 2) patient participation, 3) adaptive radiotherapy 4) surface guided radiotherapy and tracking. Most innovations (13/16) were implemented with a delay, with many comparable challenges: e.g. shortage of personnel (7/16) and prioritization of projects (9/16). The website allows users to upload and search for projects, including implementation experiences. After 1 year, 14 projects were uploaded. The qualitative evaluation was largely positive with room for improvement, i.e.75 % would recommend the website to others. CONCLUSION: This study showed that RTCs experience comparable challenges when implementing innovations, thereby underlining the need for a platform to share implementation-lessons learned. The first concept of this platform was evaluated positively.

Global Perceptions on ERAS® in Pancreatoduodenectomy.

BACKGROUND: Uptake of ERAS® pathways for pancreatic surgery have been slow and impacted by low compliance. OBJECTIVE: To explore global awareness, perceptions and practice of ERAS® peri-pancreatoduodenectomy (PD). METHODS: A structured, web-based survey (EPSILON) was administered through the ERAS® society and IHPBA membership. RESULTS: The 140 respondents included predominantly males (86.4%), from Europe (45%), practicing surgery (95%) at academic/teaching hospitals (63.6%) over a period of 10-20 years (38.6%). Most respondents identified themselves as general surgeons (68.6%) with 40.7% reporting an annual PD volume of 20-50 cases, practicing post-PD clinical pathways (37.9%), with 31.4% of respondents auditing their outcomes annually. Reduced medical complications, cost and hospital length of stay, and improved patient satisfaction were perceived benefits of compliance to enhancing-recovery. Multidisciplinary co-ordination was considered the most important factor in the implementation and sustainability of peri-PD ERAS® pathways, while reluctance to change among health care practitioners, difficulties in data collection and audit, lack of administrative support, and recruitment of an ERAS® dedicated nurse were reported to be important barriers. CONCLUSIONS: The EPSILON survey highlighted global clinician perceptions regarding the benefits of compliance to peri-PD ERAS®, the importance of individual components, perceived facilitators and barriers, to the implementation and sustainability of these pathways.

Recurarization with magnesium sulfate administered after two minutes sugammadex reversal: A randomized, double-blind, controlled trial.

STUDY OBJECTIVE: The current study tested the hypothesis that magnesium sulfate after reversal with sugammadex causes recurarization. DESIGN: A single-center, prospective, randomized, double-blind, controlled trial. SETTING: Terciary care hospital in Rio de Janeiro, Brazil. PATIENTS: Included 60 patients undergoing for elective otolaryngological surgery. INTERVENTIONS: All patients received total intravenous anesthesia and a single dose of rocuronium (0.6 mg/kg). In 30 patients, the neuromuscular blockade was reversed with sugammadex (4 mg/kg) at the reappearance of one or two posttetanic counts (deep-blockade series). In 30 other patients, sugammadex (2 mg/kg) was administered at the reappearance of the second twitch of the train-of-four (moderate-blockade series). After the normalized train-of-four ratio recovered to ≥0.9, the patients in each series were randomized to receive intravenous magnesium sulfate (60 mg/kg) or placebo for 10 min. Neuromuscular function was measured by acceleromyography. MEASUREMENTS: The primary outcome was the number of patients who exhibited recurarization (normalized train-of-four ratio < 0.9). The secondary outcome was rescue with an additional dose of sugammadex after 60 min. MAIN RESULTS: In the deep-blockade series, a normalized train-of-four ratio < 0.9 occurred in 9/14 (64%) patients receiving magnesium sulfate and 1/14 (7%) receiving placebo, RR 9.0 (95% CI: 62-1.30), and (p = 0.002), with four rescues with sugammadex. In the moderate-blockade series, neuromuscular blockade recurred in 11/15 (73%) patients receiving magnesium sulfate and in 0/14 (0%) receiving placebo (p < 0.001), with two rescues. The absolute differences in recurarization were 57% and 73% in the deep-blockade and moderate-blockade, respectively. CONCLUSIONS: Single-dose magnesium sulfate led to a normalized train-of-four ratio < 0.9, 2 min after recovery from rocuronium-induced deep and moderate neuromuscular blockade using sugammadex. Additional sugammadex reversed prolonged recurarization.

Enhanced Recovery After Surgery and Elderly Patients: Advances.

Enhanced recovery after surgery (ERAS) is a new way of working where evidence-based care elements are assembled to form a care pathway involving the patient's entire journey through surgery. Many elements included in ERAS have stress-reducing effects on the body or helps avoid side effects associated with alternative treatment options. This leads to less overall stress from the injury caused by the operation and helps facilitate recovery. In old, frail patients with concomitant diseases and less physical reserves, this may help explain why the ERAS care is reported to be beneficial for this specific patient group.

A fatal mono-intoxication with 4-fluoroisobutyrylfentanyl: Case report with postmortem concentrations.

We report on a case of a 35-year-old man who died suddenly and unexpectedly due to a 4-fluoroisobutyrylfentanyl (4-FIBF) mono-intoxication. Pathological, toxicological and chemical investigations were conducted at the Netherlands Forensic Institute. A full three-cavity forensic pathological examination was performed according to international guidelines. Biological samples obtained during autopsy were comprehensively investigated for the presence of toxic substances using headspace gas chromatography (GC) with flame ionization detection, liquid chromatography-time-of-flight mass spectrometry (LC-TOF-MS), GC-MS, high-performance LC with diode array detection and LC-tandem MS (LC-MS-MS). The seized crystalline substance found next to the body was investigated using a presumptive color test, GC-MS, Fourier-transform infrared spectroscopy and nuclear magnetic resonance. Pathological investigation identified minor lymphocytic infiltrates in the heart, considered irrelevant for the cause of death. Toxicological analysis of the victims' blood indicated the presence of a fluorobutyrylfentanyl (FBF) isomer, with no other compounds detected. The FBF isomer was identified in the seized crystalline substance as 4-FIBF. 4-FIBF concentrations were quantified in femoral blood (0.030 mg/L), heart blood (0.12 mg/L), vitreous humor (0.067 mg/L), brain tissue (>0.081 mg/kg), liver tissue (0.44 mg/kg) and urine (approximately 0.01 mg/L). Based on the outcomes of the pathological, toxicological and chemical investigations, the cause of death of the deceased was attributed to a fatal 4-FIBF mono-intoxication. The presented case underlines the added value of a combined bioanalytical and chemical investigative approach to identify and subsequently quantify fentanyl isomers in postmortem cases. Furthermore, it demonstrates the importance of investigating the postmortem redistribution of novel fentanyl analogs to establish reference values and to subsequently allow for correct interpretation of cause of death analysis in future casework.

From once-weekly to semi-weekly whole prostate gland stereotactic radiotherapy with focal boosting: Primary endpoint analysis of the multicenter phase II hypo-FLAME 2.0 trial.

BACKGROUND AND PURPOSE: The hypo-FLAME trial showed that once-weekly (QW) focal boosted prostate stereotactic body radiotherapy (SBRT) is associated with acceptable acute genitourinary (GU) and gastrointestinal (GI) toxicity. Currently, we investigated the safety of reducing the overall treatment time (OTT) of focal boosted prostate SBRT from 29 to 15 days. MATERIAL AND METHODS: Patients with intermediate- and high-risk prostate cancer were treated with SBRT delivering 35 Gy in 5 fractions to the whole prostate gland with an iso-toxic boost up to 50 Gy to the intraprostatic lesion(s) in a semi-weekly (BIW) schedule. The primary endpoint was radiation-induced acute toxicity (CTCAE v5.0). Changes in quality of life (QoL) were examined in terms of proportions achieving a minimal clinically important change (MCIC). Finally, acute toxicity and QoL scores of the BIW schedule were compared with the results of the prior QW hypo-FLAME schedule (n = 100). RESULTS: Between August 2020 and February 2022, 124 patients were enrolled and treated BIW. No grade ≥3 GU or GI toxicity was observed. The 90-days cumulative incidence of grade 2 GU and GI toxicity rates were 47.5% and 7.4%, respectively. Patients treated QW scored significant less grade 2 GU toxicity (34.0%, p = 0.01). No significant differences in acute GI toxicity were observed. Furthermore, patients treated QW had a superior acute bowel and urinary QoL. CONCLUSION: Semi-weekly prostate SBRT with iso-toxic focal boosting is associated with acceptable acute GU and GI toxicity. Based on the comparison between the QW and BIW schedule, patients should be counselled regarding the short-term advantages of a more protracted schedule. Registration number ClinicalTrials.gov: NCT04045717.

Fatal gastric volvulus: forensic pathology considerations and postmortem CT findings.

Gastric volvulus is a rare cause of gastric obstruction, due to the rotation of the stomach by more than 180°. It is a rare but life-threatening medical emergency that is considered difficult to diagnose at the initial clinical presentation. Forensic pathologists may be presented with gastric volvulus in several ways, for instance, as a cause of sudden and unexpected death or in the context of suspected clinical errors. The post-mortem examination of gastric volvulus may be challenging, due to the specific technical issues it presents and the various mechanisms by which volvulus may cause death. We therefore present five cases of gastric volvulus that in combination represent almost the entire spectrum of presentations and post-mortem findings, to discuss how gastric volvulus may come to the attention of a forensic pathologist, the approach and findings at post-mortem examination (including post-mortem CT), and the variety of mechanisms by which gastric volvulus may result in death.

A framework for perioperative care for lower extremity vascular bypasses: A Consensus Statement by the Enhanced Recovery after Surgery (ERAS®) Society and Society for Vascular Surgery.

The Society for Vascular Surgery and the Enhanced Recovery After Surgery (ERAS) Society formally collaborated and elected an international, multi-disciplinary panel of experts to review the literature and provide evidence-based suggestions for coordinated perioperative care for patients undergoing infrainguinal bypass surgery for peripheral artery disease. Structured around the ERAS core elements, 26 suggestions were made and organized into preadmission, preoperative, intraoperative, and postoperative sections.

Anaesthesia role in enhanced recovery after surgery: a revolution in care outcomes.

PURPOSE OF REVIEW: Enhanced recovery after surgery (ERAS) has revolutionized care outcomes. The purpose of this review is to provide an overview of how ERAS changed healthcare outcomes. RECENT FINDINGS: Development of multidisciplinary evidence-based ERAS guidelines for specific surgical specialties and systematic implementation of these guidelines resulted in improved healthcare outcomes, reduction in length of stay, reduction in complications and improved survival. The value of audit of the outcomes is essential for implementation and to improve healthcare. Healthcare economics analysis related to the implementation of ERAS showed significant cost savings up to a return to investment ratio of more than seven. SUMMARY: ERAS has revolutionized healthcare by developing evidence-based ERAS guidelines and systematic implementation of these guidelines. Audit of outcomes is essential, not only to improve healthcare but also to significantly save healthcare expenditures.

NaCl 3% Bolus Therapy as Emergency Treatment for Severe Hyponatremia: Comparison of 100 mL vs 250 mL.

CONTEXT: The aim of initial treatment of severe hyponatremia is to rapidly increase serum sodium to reduce the complications of cerebral edema. The optimal strategy to achieve this goal safely is still under debate. OBJECTIVE: To compare the efficacy and safety of 100 and 250 mL NaCl 3% rapid bolus therapy as initial treatment of severe hypotonic hyponatremia. METHODS: Retrospective analysis of patients admitted to a teaching hospital in The Netherlands between 2017 and 2019. The patients were 130 adults with severe hypotonic hyponatremia, defined as serum sodium ≤ 120 mmol/L. A bolus of either 100 mL (n = 63) or 250 mL (n = 67) NaCl 3% was the initial treatment. Successful treatment was defined as a rise in serum sodium ≥ 5 mmol/L within the first 4 hours after bolus therapy. Overcorrection of serum sodium was defined as an increase of more than 10 mmol/L in the first 24 hours. RESULTS: The percentage of patients with a rise in serum sodium ≥5 mmol/L within 4 hours was 32% and 52% after a bolus of 100 and 250 mL, respectively (P = .018). Overcorrection of serum sodium was observed after a median of 13 hours (range 9-17 hours) in 21% of patients in both treatment groups (P = .971). Osmotic demyelination syndrome did not occur. CONCLUSION: Initial treatment of severe hypotonic hyponatremia is more effective with a NaCl 3% bolus of 250 mL than of 100 mL and does not increase the risk of overcorrection.

Developing expert international consensus statements for opioid-sparing analgesia using the Delphi method.

INTRODUCTION: The management of postoperative pain in anaesthesia is evolving with a deeper understanding of associating multiple modalities and analgesic medications. However, the motivations and barriers regarding the adoption of opioid-sparing analgesia are not well known. METHODS: We designed a modified Delphi survey to explore the perspectives and opinions of expert panellists with regard to opioid-sparing multimodal analgesia. 29 anaesthetists underwent an evolving three-round questionnaire to determine the level of agreement on certain aspects of multimodal analgesia, with the last round deciding if each statement was a priority. RESULTS: The results were aggregated and a consensus, defined as achievement of over 75% on the Likert scale, was reached for five out of eight statements. The panellists agreed there was a strong body of evidence supporting opioid-sparing multimodal analgesia. However, there existed multiple barriers to widespread adoption, foremost the lack of training and education, as well as the reluctance to change existing practices. Practical issues such as cost effectiveness, increased workload, or the lack of supply of anaesthetic agents were not perceived to be as critical in preventing adoption. CONCLUSION: Thus, a focus on developing specific guidelines for multimodal analgesia and addressing gaps in education may improve the adoption of opioid-sparing analgesia.

Effect of preoperative metabolic profiling to reduce the risk of kidney stones after bariatric surgery in patients with a history of stone formation.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is associated with an increased risk of kidney stone formation. This is not observed after sleeve gastrectomy (SG). OBJECTIVES: Aim of this study was to assess whether preoperative metabolic profiling is helpful in selecting the most optimal bariatric procedure for patients with a kidney stone history. SETTING: General hospital, the Netherlands. METHODS: Patients with a kidney stone history and in the run up to bariatric surgery were screened with non-contrast abdominal computed tomography (CT), serum profiling, and 24-hour urine analysis. Those with stones on radiologic imaging and/or high preoperative urinary oxalate were advised to undergo SG instead of RYGB. Pre- and postoperative urine and serum profile differences between both groups were evaluated retrospectively. RESULTS: Postoperatively, RYGB (N = 28, M:F = 8:20) was associated with a 23.5% reduction in urinary volume, a 85% increase in urinary oxalate excretion with a 230% increase in calcium oxalate (CaOx) supersaturation and a 62% decrease in urinary citrate. Although SG (N = 30, M:F = 12:18) was also associated with a reduction in urinary volume, it had no adverse effects on urinary oxalate and citrate excretion, nor on calcium oxalate supersaturation (CaOx-SS). Both RYGB and SG showed favorable effects on postoperative sodium, calcium, uric acid, and phosphate excretion. CONCLUSIONS: This study indicates that preoperative metabolic profiling is important to select the optimal bariatric procedure in patients with an a priori increased risk of kidney stone development. These patients should be strongly encouraged to undergo SG instead of RYGB to prevent progressive or recurrent kidney stone disease.

Accuracy of Bioimpedance Spectroscopy in the Detection of Hydration Changes in Patients on Hemodialysis.

OBJECTIVES: The body composition monitor (BCM) is a bioimpedance spectroscopy device, specifically developed for patients on hemodialysis (HD) to improve ultrafiltration (UF) programming, based on an objective assessment of the degree of overhydration (OH) at the start of HD. However, its acceptance in clinical practice remains limited because of concerns about the accuracy at the individual level. The aim of this study is to examine the performance of the BCM and to identify means of improvement. METHODS: Precision of the OH estimate was assessed by 6 consecutive measurements in 24 patients on HD. Accuracy was examined in 45 patients, by comparing the change in OH (ΔOH) during HD with UF volume. Accuracy was considered acceptable if the volume error in individual patients was ≤0.5 L. RESULTS: The OH estimate had an analytical precision of 1.0 ± 0.4%. The correlation between UF volume and ΔOH was moderate (Slope = 0.66, R2 = 0.44, P < .001) and indicated underestimation of UF volume, in particular for high UF volumes. Accuracy at individual level was highly variable. A volume error >0.5 L occurred in 44% of patients. Accuracy improved over the course of HD, with a decrease in total error range from 2.3 L in the first hour to 1.1 L in the final hour of HD. CONCLUSIONS: The accuracy of BCM volume change estimates is highly variable and below requirements of daily practice. Improvement may be achieved by a switch to an end-of-HD measurement.

Application of postmortem imaging modalities in cases of sudden death due to cardiovascular diseases-current achievements and limitations from a pathology perspective : Endorsed by the Association for European Cardiovascular Pathology and by the International Society of Forensic Radiology and Imaging.

Postmortem imaging (PMI) is increasingly used in postmortem practice and is considered a potential alternative to a conventional autopsy, particularly in case of sudden cardiac deaths (SCD). In 2017, the Association for European Cardiovascular Pathology (AECVP) published guidelines on how to perform an autopsy in such cases, which is still considered the gold standard, but the diagnostic value of PMI herein was not analyzed in detail. At present, significant progress has been made in the PMI diagnosis of acute ischemic heart disease, the most important cause of SCD, while the introduction of postmortem CT angiography (PMCTA) has improved the visualization of several parameters of coronary artery pathology that can support a diagnosis of SCD. Postmortem magnetic resonance (PMMR) allows the detection of acute myocardial injury-related edema. However, PMI has limitations when compared to clinical imaging, which severely impacts the postmortem diagnosis of myocardial injuries (ischemic versus non-ischemic), the age-dating of coronary occlusion (acute versus old), other potentially SCD-related cardiac lesions (e.g., the distinctive morphologies of cardiomyopathies), aortic diseases underlying dissection or rupture, or pulmonary embolism. In these instances, PMI cannot replace a histopathological examination for a final diagnosis. Emerging minimally invasive techniques at PMI such as image-guided biopsies of the myocardium or the aorta, provide promising results that warrant further investigations. The rapid developments in the field of postmortem imaging imply that the diagnosis of sudden death due to cardiovascular diseases will soon require detailed knowledge of both postmortem radiology and of pathology.
