RESUMO
Five-year survival following childhood acute myeloid leukemia (AML) has increased following improvements in treatment and supportive care. Long-term health outcomes are unknown. To address this, cumulative incidence of late mortality and grades 3 to 5 chronic health condition (CHC) were estimated among 5-year AML survivors diagnosed between 1970 and 1999. Survivors were compared by treatment group (hematopoietic cell transplantation [HCT], chemotherapy with cranial radiation [chemo + CRT], chemotherapy only [chemo-only]), and diagnosis decade. Self-reported health status was compared across treatments, diagnosis decade, and with siblings. Among 856 survivors (median diagnosis age, 7.1 years; median age at last follow-up, 29.4 years), 20-year late mortality cumulative incidence was highest after HCT (13.9%; 95% confidence interval [CI], 10.0%-17.8%; chemo + CRT, 7.6%; 95% CI, 2.2%-13.1%; chemo-only, 5.1%; 95% CI, 2.8%-7.4%). Cumulative incidence of mortality for HCT survivors diagnosed in the 1990s (8.5%; 95% CI, 4.1%-12.8%) was lower vs those diagnosed in the 1970s (38.9%; 95% CI, 16.4%-61.4%). Most survivors did not experience any grade 3 to 5 CHC after 20 years (HCT, 45.8%; chemo + CRT, 23.7%; chemo-only, 27.0%). Furthermore, a temporal reduction in CHC cumulative incidence was seen after HCT (1970s, 76.1%; 1990s, 38.3%; P = .02), mirroring reduced use of total body irradiation. Self-reported health status was good to excellent for 88.2% of survivors; however, this was lower than that for siblings (94.8%; P < .0001). Although HCT is associated with greater long-term morbidity and mortality than chemotherapy-based treatment, gaps have narrowed, and all treatment groups report favorable health status.

BACKGROUND: The Center for International Blood and Marrow Transplant Research (CIBMTR) provides a 1-year overall survival calculator to estimate outcomes for individual patients before they undergo allogeneic hematopoietic cell transplantation (HCT) to inform risk. The calculator considers pre-HCT clinical and demographic characteristics, but not patient-reported outcomes (PROs). Because pre-HCT PRO scores have been associated with post-HCT outcomes, the authors hypothesized that adding PRO scores to the calculator would enhance its predictive power. METHODS: Clinical data were obtained from the CIBMTR and the Blood and Marrow Transplant Clinical Trials Network. The PRO measures used were the 36-Item Short Form Survey (SF-36) and the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation. One thousand thirty-three adult patients were included. RESULTS: When adjusted for clinical characteristics, the SF-36 physical component score was significantly predictive of 1-year survival (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.81-0.95; p = .0015), whereas the mental component score was not (HR, 1.02; 95% CI, 0.95-1.10; p = 0.6396). The baseline single general health question on the SF-36 was also significantly associated with mortality (HR, 1.91 for those reporting fair/poor health vs. good, very good, or excellent health; 95% CI, 1.33-2.76; p = .0005). The addition of PRO scores to the calculator did not result in a significant change in the model's predictive ability. Self-reported pre-HCT scores were strongly predictive of self-reported health status (odds ratio, 3.35; 95% CI, 1.66-6.75; p = .0007) and quality of life (odds ratio, 3.24; 95% CI, 1.93-5.41; p < .0001) after HCT. CONCLUSIONS: The authors confirmed the significant, independent association of pre-HCT PRO scores with overall survival, although adding PRO scores to the survival calculator did not improve its performance. They also demonstrated that a single general health question was as accurate as the full measure for predicting survival, an important finding that may reduce respondent burden and promote its inclusion in routine clinical practice. Validation of these findings should be performed.

PURPOSE: Treatment strategies for osteosarcoma evolving between 1970 and 1999 improved 5-year survival and continue as standard of care today. This report evaluates the impact of these evolving therapies on long-term health outcomes. METHODS: Five-year survivors of childhood osteosarcoma in CCSS treated from 1970 to 1999 were evaluated for late (>5 years from diagnosis) mortality, chronic health conditions (CHCs), and health status using piecewise-exponential and logistical models. Comparisons were made between survivors and siblings without cancer, and among survivors examining historical and current standard chemotherapies (e.g., methotrexate/doxorubicin/cisplatin [MAP] vs. others), specific chemotherapy agents and surgical approaches (amputation vs. limb salvage [LS]). Models were evaluated adjusting for attained age, sex, race, ethnicity, and age at diagnosis. RESULTS: A total of 1257 survivors of osteosarcoma were followed on average for 24.4 years. Twenty-year all-cause late mortality was 13.3% (95% confidence interval [CI]: 11.7%-14.9%) overall and 11.7% (95% CI: 6.9%-16.5%) for the subset treated with MAP plus LS. Survivors were at higher risk of CHCs (rate ratio [RR] 3.7, 95% CI: 3.2-4.3) than the sibling cohort, most notably having more serious cardiac, musculoskeletal, and hearing CHCs. Within the survivor cohort, the risk of severe CHCs was twice as high with MAP versus no chemotherapy (RR 2.1, 95% CI: 1.3-3.4). Compared with primary amputation, serious musculoskeletal CHCs were higher after LS (RR 6.6, 95% CI: 3.6-13.4), without discernable differences in health status. CONCLUSION: Contemporary osteosarcoma therapy with MAP plus LS, while improving 5-year disease-free survival, continues to be associated with a high burden of late mortality, CHCs, and health status limitations.
RESUMO
Dexamethasone use during hematopoietic cell transplant (HCT) conditioning varies between pediatric centers. This study aimed to estimate the difference in 1-year treatment-related mortality (TRM) between patients who did or did not receive dexamethasone during HCT conditioning. Secondary objectives were to estimate the difference between dexamethasone-exposed and dexamethasone-unexposed groups in 1-year event-free survival (EFS), time to neutrophil engraftment, acute graft-versus-host disease (aGVHD), and invasive fungal disease (IFD) at day + 100. This was a seven-site, international, retrospective cohort study. Patients < 18 years old undergoing their first allogeneic or autologous myeloablative HCT for hematologic malignancy or aplastic anemia between January 1, 2012, and July 31, 2017, were included. To control for potential confounders, propensity score weighting was used to calculate the standardized mean difference for all endpoints. Among 242 patients, 140 received dexamethasone during HCT conditioning and 102 did not. TRM was unaffected by dexamethasone exposure (1.7%; 95% CI - 7.4, 10.2%). Between-group differences in secondary outcomes were small. However, dexamethasone exposure significantly increased possible, probable, and proven IFD incidence (9.0%, 95% CI 0.8, 17.3%). TRM is not increased in pediatric patients who receive dexamethasone during HCT conditioning. Clinicians should consider potential IFD risk when selecting chemotherapy-induced vomiting prophylaxis for pediatric HCT patients.

PURPOSE: Point-of-care ultrasound (POCUS) allows for rapid bedside assessment and guidance of patient care. Recently, POCUS was included as a mandatory component of Canadian anesthesiology training; however, there is no national consensus regarding the competencies to guide curriculum development. We therefore aimed to define national residency competencies for basic perioperative POCUS proficiency. METHODS: We adopted a Delphi process to delineate relevant POCUS competencies whereby we circulated an online survey to academic anesthesiologists identified as POCUS leads/experts (n = 25) at all 17 Canadian anesthesiology residency programs. After reviewing a list of competencies derived from the Royal College of Physicians and Surgeons of Canada's National Curriculum, we asked participants to accept, refine, delete, or add competencies. Three rounds were completed between 2022 and 2023. We discarded items with < 50% agreement, revised those with 50-79% agreement based upon feedback provided, and maintained unrevised those items with ≥ 80% agreement. RESULTS: We initially identified and circulated (Round 1) 74 competencies across 19 clinical domains (e.g., basics of ultrasound [equipment, nomenclature, clinical governance, physics]; cardiac [left ventricle, right ventricle, valve assessment, pericardial effusion, intravascular volume status] and lung ultrasound anatomy, image acquisition, and image interpretation; and clinical applications [monitoring and serial assessments, persistent hypotension, respiratory distress, cardiac arrest]). After three Delphi rounds (and 100% response rate maintained), panellists ultimately agreed upon 75 competencies. CONCLUSION: Through national expert consensus, this study identified POCUS competencies suitable for curriculum development and assessment in perioperative anesthesiology. Next steps include designing and piloting a POCUS curriculum and assessment tool(s) based upon these nationally defined competencies.
RéSUMé: OBJECTIF: L'échographie ciblée (POCUS) permet une évaluation rapide au chevet des patient·es et l'orientation des soins aux patient·es. Récemment, l'échographie ciblée a été incluse en tant que composante obligatoire de la formation en anesthésiologie au Canada; cependant, il n'y a pas de consensus national sur les compétences qui guideront l'élaboration des programmes d'études. Nous avons donc cherché à définir les compétences à inclure dans les programmes de résidence nationaux pour acquérir des compétences de base en échographie ciblée périopératoire. MéTHODE: Nous avons adopté un processus Delphi pour délimiter les compétences pertinentes en échographie ciblée, processus dans le cadre duquel nous avons fait circuler un sondage en ligne auprès d'anesthésiologistes universitaires identifié·es comme des responsables/expert·es en échographie ciblée (n = 25) dans les 17 programmes canadiens de résidence en anesthésiologie. Après avoir examiné une liste de compétences tirées du programme d'études national du Collège royal des médecins et chirurgiens du Canada, nous avons demandé aux participant·es d'accepter, de peaufiner, de supprimer ou d'ajouter des compétences. Trois rondes ont été complétées entre 2022 et 2023. Nous avons écarté les éléments ayant < 50 % d'accord, révisé ceux avec 50 à 79 % d'accord en fonction des commentaires fournis, et maintenu sans révision les éléments obtenant ≥ 80 % d'accord. RéSULTATS: Nous avons d'abord identifié et diffusé (ronde 1) 74 compétences dans 19 domaines cliniques (p. ex., les bases de l'échographie [équipement, nomenclature, gouvernance clinique, physique]; anatomie échographique cardiaque [ventricule gauche, ventricule droit, évaluation valvulaire, épanchement péricardique, état du volume intravasculaire] et pulmonaire [acquisition et interprétation d'images]; et applications cliniques [surveillance et évaluations en série, hypotension persistante, détresse respiratoire, arrêt cardiaque]). Après trois rondes Delphi (et un taux de réponse de 100 % maintenu), les panélistes se sont finalement mis·es d'accord sur 75 compétences. CONCLUSION: Grâce à un consensus d'expert·es au pays, cette étude a permis d'identifier les compétences en échographie ciblée adaptées à l'élaboration et à l'évaluation de programmes d'études en anesthésiologie périopératoire. Les prochaines étapes comprennent la conception et la mise à l'essai d'un programme d'études et d'outils d'évaluation en échographie ciblée basés sur ces compétences définies à l'échelle nationale.

PURPOSE: Medical errors may be occasionally explained by inattentional blindness (IB), i.e., failing to notice an event/object that is in plain sight. We aimed to determine whether age/experience, restfulness/fatigue, and previous exposure to simulation education may affect IB in the anesthetic/surgical setting. METHODS: In this multicentre/multinational study, a convenience sample of 280 anesthesiologists watched an attention-demanding video of a simulated trauma patient undergoing laparotomy and (independently/anonymously) recorded the abnormalities they noticed. The video contained four expected/common abnormalities (hypotension, tachycardia, hypoxia, hypothermia) and two prominently displayed unexpected/rare events (patient's head movement, leaky central venous line). We analyzed the participants' ability to notice the expected/unexpected events (primary outcome) and the proportion of expected/unexpected events according to age group and prior exposure to simulation education (secondary outcomes). RESULTS: Anesthesiologists across all ages noticed fewer unexpected/rare events than expected/common ones. Overall, younger anesthesiologists missed fewer common events than older participants did (P = 0.02). There was no consistent association between age and perception of unexpected/rare events (P = 0.28), although the youngest cohort (< 30 yr) outperformed the other age groups. Prior simulation education did not affect the proportion of misses for the unexpected/rare events but was associated with fewer misses for the expected/common events. Self-perceived restfulness did not impact perception of events. CONCLUSION: Anesthesiologists noticed fewer unexpected/rare clinical events than expected/common ones in an attention-demanding video of a simulated trauma patient, in keeping with IB. Prior simulation training was associated with an improved ability to notice anticipated/expected events, but did not reduce IB. Our findings may have implications for understanding medical mishaps, and efforts to improve situational awareness, especially in acute perioperative and critical care settings.
RéSUMé: OBJECTIF: Les erreurs médicales peuvent parfois s'expliquer par la cécité d'inattention, soit le fait de ne pas remarquer un événement/objet qui est à la vue de tous et toutes. Notre objectif était de déterminer si l'âge/l'expérience, le repos/la fatigue et l'exposition antérieure à l'enseignement par simulation pouvaient affecter la cécité d'inattention dans le cadre de l'anesthésie/chirurgie. MéTHODE: Dans cette étude multicentrique/multinationale, un échantillon de convenance de 280 anesthésiologistes ont visionné une vidéo exigeant l'attention portant sur un patient de trauma simulé bénéficiant d'une laparotomie et ont enregistré (de manière indépendante/anonyme) les anomalies qu'ils et elles ont remarquées. La vidéo contenait quatre anomalies attendues/courantes (hypotension, tachycardie, hypoxie, hypothermie) et deux événements inattendus/rares bien en vue (mouvement de la tête du patient, fuite du cathéter veineux central). Nous avons analysé la capacité des participant·es à remarquer les événements attendus/inattendus (critère d'évaluation principal) et la proportion d'événements attendus/inattendus selon le groupe d'âge et l'exposition antérieure à l'enseignement par simulation (critères d'évaluation secondaires). RéSULTATS: Les anesthésiologistes de tous âges ont remarqué moins d'événements inattendus/rares que d'événements attendus/courants. Globalement, les anesthésiologistes plus jeunes ont manqué moins d'événements courants que leurs congénères plus âgé·es (P = 0,02). Il n'y avait pas d'association constante entre l'âge et la perception d'événements inattendus ou rares (P = 0,28), bien que la cohorte la plus jeune (< 30 ans) ait surpassé les autres groupes d'âge. La formation antérieure par simulation n'a pas eu d'incidence sur la proportion d'inobservation des événements inattendus ou rares, mais a été associée à moins de cécité d'inattention envers les événements attendus ou courants. Le repos perçu n'a pas eu d'impact sur la perception des événements. CONCLUSION: Les anesthésiologistes ont remarqué moins d'événements cliniques inattendus/rares que d'événements attendus/courants dans une vidéo exigeant l'attention portant sur la simulation d'un patient traumatisé, ce qui s'inscrit dans la cécité d'inattention. La formation préalable par simulation était associée à une meilleure capacité à remarquer les événements anticipés/attendus, mais ne réduisait pas la cécité d'inattention. Nos résultats peuvent avoir des implications pour la compréhension des accidents médicaux et les efforts visant à améliorer la conscience situationnelle, en particulier dans les contextes de soins périopératoires aigus et de soins intensifs.
RESUMO
PURPOSE OF REVIEW: To summarize the mechanism of action, clinical outcomes, and perioperative implications of glucagon-like peptide-1 receptor agonists (GLP-1-RAs). Specifically, this review focuses on the available literature surrounding complications (primarily, bronchoaspiration) and current recommendations, as well as knowledge gaps and future research directions on the perioperative management of GLP-1-RAs. RECENT FINDINGS: GLP-1-RAs are known to delay gastric emptying. Accordingly, recent case reports and retrospective observational studies, while anecdotal, suggest that the perioperative use of GLP-1-RAs may increase the risk of bronchoaspiration despite fasting intervals that comply with (and often exceed) current guidelines. As a result, guidelines and safety bulletins have been published by several Anesthesiology Societies. SUMMARY: While rapidly emerging evidence suggests that perioperative GLP-1-RAs use is associated with delayed gastric emptying and increased risk of bronchoaspiration (particularly in patients undergoing general anesthesia and/or deep sedation), high-quality studies are needed to provide definitive answers with respect to the safety and duration of preoperative drug cessation, and optimal fasting intervals according to the specific GLP-1-RA agent, the dose/duration of administration, and patient-specific factors. Meanwhile, clinicians must be aware of the potential risks associated with the perioperative use of GLP-1-RAs and follow the recommendations put forth by their respective Anesthesiology Societies.

BACKGROUND: Survivorship education and anticipatory guidance represent an unmet need for pediatric, adolescent, and young adult (AYA) cancer survivors and their caregivers when treatment ends. This pilot study evaluated the feasibility, acceptability, and preliminary efficacy of a structured transition program, bridging treatment to survivorship, to reduce distress and anxiety and increase perceived preparedness for survivors and caregivers. PROCEDURE: Bridge to Next Steps is a two-visit program, within 8 weeks prior to treatment completion and 7 months post treatment, which provides survivorship education, psychosocial screening, and resources. Fifty survivors (age range 1-23 years) and 46 caregivers participated. Participants completed pre- and post-intervention measures: Distress Thermometer and Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety/emotional distress (ages ≥8 years), and perceived preparedness survey (ages ≥14 years). AYA survivors and caregivers completed a post-intervention acceptability survey. RESULTS: Most participants (77.8%) completed both visits, and most AYA survivors (57.1%) and caregivers (76.5%) endorsed the program as helpful. Caregivers' distress and anxiety scores decreased from pre to post intervention (p < .01). Survivors' scores remained the same, which were low at baseline. Survivors and caregivers felt more prepared for survivorship from pre to post intervention (p = .02, <.01, respectively). CONCLUSIONS: Bridge to Next Steps was feasible and acceptable for most participants. AYA survivors and caregivers felt more prepared for survivorship care after participation. Caregivers reported decreased anxiety and distress from pre to post Bridge, whereas survivors remained at a low level for both. Effective transition programs that better prepare and support pediatric and AYA cancer survivors and families from active treatment to survivorship care can contribute to healthy adjustment.

PURPOSE: Survivorship care plans (SCPs) have been instrumental in aiding transition from cancer treatment to survivorship care, which contains the diagnosis, treatment, potential late effects, and recommended follow-up. There has been paucity of research on its efficacy and lack of guidelines on development and delivery of SCPs. The Next Steps Survivorship Clinic at Children's Wisconsin uses a Survivorship Healthcare Passport (SHP), a SCP pocket-sized card. This study aims to improve understanding of patient and parent use of the SHP at a single institution. MATERIALS AND METHODS: An electronic survey was distributed to cancer survivors (14 to 28 y old) and parents/guardians who received the SCP. Data was analyzed with descriptive and correlation statistics. RESULTS: Older survivors were reliable in carrying their SHP, and endorsed greater confidence in understanding its contents leading to a notion of improved ability to coordinate care. Younger survivors tend to rely on their parents. A preference for a smartphone application as another platform was noted. CONCLUSIONS: This form of SCP has shown to benefit older survivors which directly impacts the notion of efficacy in care coordination. IMPLICATION FOR CANCER SURVIVORS: Providing easy-to-access information may encourage survivors to advocate for their health and to facilitate transition of care.

Wiskott-Aldrich syndrome (WAS) is an X-linked disease caused by mutations in the WAS gene, leading to thrombocytopenia, eczema, recurrent infections, autoimmune disease, and malignancy. Hematopoietic cell transplantation (HCT) is the primary curative approach, with the goal of correcting the underlying immunodeficiency and thrombocytopenia. HCT outcomes have improved over time, particularly for patients with HLA-matched sibling and unrelated donors. We report the outcomes of 129 patients with WAS who underwent HCT at 29 Primary Immune Deficiency Treatment Consortium centers from 2005 through 2015. Median age at HCT was 1.2 years. Most patients (65%) received myeloablative busulfan-based conditioning. With a median follow-up of 4.5 years, the 5-year overall survival (OS) was 91%. Superior 5-year OS was observed in patients <5 vs ≥5 years of age at the time of HCT (94% vs 66%; overall P = .0008). OS was excellent regardless of donor type, even in cord blood recipients (90%). Conditioning intensity did not affect OS, but was associated with donor T-cell and myeloid engraftment after HCT. Specifically, patients who received fludarabine/melphalan-based reduced-intensity regimens were more likely to have donor myeloid chimerism <50% early after HCT. In addition, higher platelet counts were observed among recipients who achieved full (>95%) vs low-level (5%-49%) donor myeloid engraftment. In summary, HCT outcomes for WAS have improved since 2005, compared with prior reports. HCT at a younger age continues to be associated with superior outcomes supporting the recommendation for early HCT. High-level donor myeloid engraftment is important for platelet reconstitution after either myeloablative or busulfan-containing reduced intensity conditioning. (This trial was registered at www.clinicaltrials.gov as #NCT02064933.).

OBJECTIVE: Despite advances in health care and ample resources, post-partum hemorrhage (PPH) rates are increasing in high income countries. Although guidelines recommend therapeutic uterotonics, timing of administration is open to judgement and most often based on (inherently inaccurate) visual estimates of blood loss. With severe hemorrhage, every minute of delay can have significant consequences. Our objective was to examine the timing of uterotonic administration and its impact upon maternal outcomes. We hypothesized that increased time to uterotonic administration following the identification of PPH would be associated with a greater decline in hemoglobin (Hb) and higher odds of hypotension and transfusion. METHODS: We reviewed all cases of PPH that occurred at an academic centre between June 2015 and September 2017. All cases of primary PPH (i.e., those declared within 24 h of delivery with estimated blood loss [EBL] >500 mL for vaginal and >1000 mL for cesarean deliveries) were analyzed. Patient records were excluded if they were missing information regarding time of PPH declaration, uterotonic administration, and/or Hb measures, or if a pre-existing medical condition could have contributed to PPH. RESULTS: Of 4397 births, there were 259 (5.9%) cases of primary PPH, of which 128 were included in this analysis. For these patients, each 5-minute delay in uterotonic treatment was associated with 26% higher odds of hypotension following delivery of any type. For vaginal deliveries (n = 86), each 5-minute delay was associated with 31% and 34% higher odds of hypotension and transfusion, respectively. CONCLUSION: In this study, delay in administration of therapeutic uterotonics was associated with a higher incidence of hypotension and transfusion in primary PPH patients.

Chimeric antigen receptor (CAR) T-cells, engineered autologous T-cells that target antigens found in leukemia, have shown durable remissions in relapsed acute lymphoblastic leukemia (ALL). Infant ALL with KMT2A rearrangements (KMT2Ar) is a rare, aggressive form of leukemia associated with extramedullary disease both at diagnosis and at relapse, and overall outcomes for these patients are dismal. Here we report the successful use of tisagenlecleucel, a CAR T-cell product approved for relapsed/refractory ALL, in a patient with KMT2Ar infant ALL who was treated for combined marrow and extramedullary (renal) relapse.

Advancements in hematopoietic cell transplantation (HCT) have led to increased survivorship rates in many childhood diseases. However, this growing group of long-term survivors face a myriad of late effects. There are currently limited guidelines for surveillance of gastrointestinal polyps for pediatric transplant patients. Here we describe 5 patients undergoing HCT with total body irradiation-based conditioning regimens for leukemia who developed symptomatic polyps a median of 4.5 (range: 0.75 to 5.75) years after HCT. Because of limited surveillance guidelines in children, we conclude that the development of new or progressive symptoms related to the gastrointestinal tract deserves prompt recognition and evaluation.

PURPOSE: Postoperative analgesia following total knee arthroplasty (TKA) often includes intrathecal opioids, periarticular injection (PAI) of local anesthetic, systemic multimodal analgesia, and/or peripheral nerve blockade. The adductor canal block (ACB) provides analgesia without muscle weakness and magnesium sulphate (MgSO4) may extend its duration. The purpose of this trial was to compare the duration and quality of early post-TKA analgesia in patients receiving postoperative ACB (± MgSO4) in addition to standard care. METHODS: Elective TKA patients were randomized to: 1) sham ACB, 2) ropivacaine ACB, or 3) ropivacaine ACB with added MgSO4. All received spinal anesthesia with intrathecal morphine, intraoperative PAI, and multimodal systemic analgesia. Patients and assessors remained blinded to allocation. Anesthesiologists knew whether patients had received sham or ACB but were blinded to MgSO4. The primary outcome was time to first analgesic (via patient-controlled analgesia [PCA] with iv morphine) following ACB. Secondary outcomes were morphine consumption, side effects, visual analogue scale pain scores, satisfaction until 24 hr postoperatively, and length of stay. RESULTS: Of 130 patients, 121 were included. Nine were excluded post randomization: four were protocol violations, three did not meet inclusion criteria, and two had severe pain requiring open label blockade. There were no differences in the median [interquartile range] time to first PCA request: sham, 310 min [165-550]; ropivacaine ACB, 298 min [120-776]; and ropivacaine ACB with MgSO4, 270 min [113-780] (P = 0.96). Similarly, we detected no differences in resting pain, opioid consumption, length of stay, or associated side effects until 24 hr postoperatively. CONCLUSION: We found no analgesic benefit of a postoperative ACB, with or without added MgSO4, in TKA patients undergoing spinal anesthesia and receiving intrathecal morphine, an intraoperative PAI, and multimodal systemic analgesia. TRIAL REGISTRATION: www.clinicaltrials.gov (NCT02581683); registered 21 October 2015.
RéSUMé: OBJECTIF: L'analgésie postopératoire suivant une arthroplastie totale du genou (ATG) inclut souvent des opioïdes intrathécaux, une injection périarticulaire (IPA) d'anesthésique local, une analgésie multimodale systémique, et/ou des blocs des nerfs périphériques. Le bloc du canal des adducteurs (BCA) permet une analgésie sans faiblesse musculaire et le sulfate de magnésium (MgSO4) pourrait prolonger sa durée. L'objectif de cette étude était de comparer la durée et la qualité de l'analgésie post-ATG précoce chez les patients recevant un BCA postopératoire (± MgSO4) en plus des soins standard. MéTHODE: Des patients devant subir une ATG non urgente ont été randomisés à recevoir : 1) un BCA placebo (groupe témoin), 2) un BCA avec ropivacaïne, ou 3) un BCA avec ropivacaïne et MgSO4. Tous ont reçu une rachianesthésie avec morphine intrathécale, une IPA peropératoire, et une analgésie multimodale systémique. L'allocation a été faite à l'insu des patients et des évaluateurs. Les anesthésiologistes savaient si les patients avaient reçu un placebo ou un BCA, mais n'étaient pas informés de l'ajout ou non de MgSO4. Le critère d'évaluation principal était le temps jusqu'à la première prise d'analgésique (via une analgésie contrôlée par le patient [ACP] avec de la morphine iv) après le BCA. Les critères secondaires comprenaient la consommation de morphine, les effets secondaires, les scores de douleur sur l'échelle visuelle analogue, la satisfaction jusqu'à 24 heures postopératoires, et la durée de séjour. RéSULTATS: Sur 130 patients, 121 ont été inclus. Neuf ont été exclus après la randomisation : quatre l'ont été en raison de violations du protocole, trois ne répondaient pas aux critères d'inclusion, et deux ont ressenti des douleurs graves nécessitant un bloc sans insu. Aucune différence n'a été observée dans le temps médian [écart interquartile] jusqu'à la première demande d'ACP : placebo, 310 min [165-550]; BCA ropivacaïne, 298 min [120-776]; et BCA ropivacaïne avec MgSO4, 270 min [113-780] (P = 0,96). De la même manière, nous n'avons détecté aucune différence dans la douleur au repos, la consommation d'opioïdes, la durée de séjour, ou les effets secondaires associés jusqu'à 24 heures postopératoires. CONCLUSION: Nous n'avons trouvé aucun avantage analgésique à un BCA postopératoire, avec ou sans ajout de MgSO4, chez les patients subissant une ATG sous rachianesthésie et recevant de la morphine intrathécale, une IPA peropératoire, et une analgésie multimodale systémique.

Background: The cancellation of elective surgeries is a major problem that increases wait times, exacerbates costs and can negatively affect patients, both psychologically and physically. Our objectives were to investigate the reasons for cancellations across specialties at a single centre, to compare these reasons with previous data from the same centre between 2005 and 2009 and to examine how cancellations affected patients' lives and views of the medical system in cases when the cancellations were potentially preventable. Methods: Cancellation records of all elective surgeries scheduled between June 1, 2012, and Jan. 31, 2016, at a medium-sized, tertiary care, academic centre were retrospectively reviewed. We evaluated the rates and reasons for cancellation and interviewed a subset of patients whose surgery was cancelled for a potentially preventable reason (i.e., operating room running late, bed shortage, emergency case took place of scheduled surgery). Results: Across 11 surgical specialties, 2933 of 20 881 surgeries (14.0%) were cancelled and of these, 2448 (83.5%) were for administrative or structural reasons. Compared with the data collected previously for general, gynecological and urological procedures, cancellation rates increased from 8.1% to 11.8%. Although patients reported inconvenience, they were generally satisfied with the availability and the quality of the health care they received. Conclusion: Consistent with the previous study, our data suggest that most cancellations occur because of administrative or structural processes that are potentially preventable. Targeting these processes may help to reduce cancellations for elective surgeries and thereby improve economic efficiency and patient outcomes.
Contexte: L'annulation des chirurgies électives est un problème majeur qui allonge les temps d'attente, fait gonfler les coûts et peut affecter négativement les patients, tant psychologiquement que physiquement. Nos objectifs étaient de découvrir les raisons des annulations dans les diverses spécialités d'un seul centre, afin de comparer ces raisons à des données antérieures du même centre recueillies entre 2005 et 2009 et d'examiner en quoi les annulations affectent la vie des patients et leur perception du système médical dans les cas où les annulations auraient pu être évitées. Méthodes: Les dossiers d'annulation de toutes les chirurgies électives entre le 1er juin 2012 et le 31 janvier 2016 dans un centre hospitalier universitaire de soins tertiaires de taille moyenne ont été analysés de manière rétrospective. Nous avons évalué les taux d'annulation et les motifs, et interrogé un groupe de patients dont la chirurgie a été annulée pour des raisons potentiellement évitables (p. ex., retards au bloc opératoire, manque de lits, priorisation de cas plus urgents). Résultats: Entre les 11 spécialités chirurgicales, 2933 des 20 881 chirurgies (14,0 %) ont été annulées et parmi elles, 2448 (83,5 %) pour des raisons administratives ou structurelles. Comparativement aux données précédemment recueillies pour les interventions générales, gynécologiques et urologiques, les taux d'annulation ont augmenté de 8,1 % à 11,8 %. Même si les patients ont déploré des inconvénients, ils se sont généralement déclarés satisfaits de la qualité des soins reçus et de leur accessibilité. Conclusion: Comme lors de l'étude précédente, nos données suggèrent que les causes les plus fréquentes d'annulation sont liées à des marches à suivre administratives ou structurelles qui sont potentiellement évitables. Cibler ces marches à suivre pourrait contribuer à réduire le nombre d'annulations de chirurgies électives et améliorer de ce fait l'efficience économique et les résultats chez les patients.

The COVID-19 pandemic has created significant barriers to timely donor evaluation, cell collection, and graft transport for allogeneic hematopoietic stem cell transplantation (allo-HCT). To ensure availability of donor cells on the scheduled date of infusion, many sites now collect cryopreserved grafts before the start of pretransplantation conditioning. Post-transplantation cyclophosphamide (ptCY) is an increasingly used approach for graft-versus-host disease (GVHD) prophylaxis, but the impact of graft cryopreservation on the outcomes of allo-HCT using ptCY is not known. Using the Center for International Blood and Marrow Transplant Research (CIBMTR) database, we compared the outcomes of HCT using cryopreserved versus fresh grafts in patients undergoing HCT for hematologic malignancy with ptCY. We analyzed 274 patients with hematologic malignancy undergoing allo-HCT between 2013 and 2018 with cryopreserved grafts and ptCY. Eighteen patients received bone marrow grafts and 256 received peripheral blood stem cell grafts. These patients were matched for age, graft type, disease risk index (DRI), and propensity score with 1080 patients who underwent allo-HCT with fresh grafts. The propensity score, which is an assessment of the likelihood of receiving a fresh graft versus a cryopreserved graft, was calculated using logistic regression to account for the following: disease histology, Karnofsky Performance Score (KPS), HCT Comorbidity Index, conditioning regimen intensity, donor type, and recipient race. The primary endpoint was overall survival (OS). Secondary endpoints included acute and chronic graft-versus-host disease (GVHD), non-relapse mortality (NRM), relapse/progression and disease-free survival (DFS). Because of multiple comparisons, only P values <.01 were considered statistically significant. The 2 cohorts (cryopreserved and fresh) were similar in terms of patient age, KPS, diagnosis, DRI, HCT-CI, donor/graft source, and conditioning intensity. One-year probabilities of OS were 71.1% (95% confidence interval [CI], 68.3% to 73.8%) with fresh grafts and 70.3% (95% CI, 64.6% to 75.7%) with cryopreserved grafts (P = .81). Corresponding probabilities of OS at 2 years were 60.6% (95% CI, 57.3% to 63.8%) and 58.7% (95% CI, 51.9% to 65.4%) (P = .62). In matched-pair regression analysis, graft cryopreservation was not associated with a significantly higher risk of mortality (hazard ratio [HR] for cryopreserved versus fresh, 1.05; 95% CI, .86 to 1.29; P = .60). Similarly, rates of neutrophil recovery (HR, .91; 95% CI, .80 to 1.02; P = .12), platelet recovery (HR, .88; 95% CI, .78 to 1.00; P = .05), grade III-IV acute GVHD (HR, .78; 95% CI, .50 to 1.22; P = .27), NRM (HR, 1.16; 95% CI, .86 to 1.55; P = .32) and relapse/progression (HR, 1.21; 95% CI, .97 to 1.50; P = .09) were similar with cryopreserved grafts versus fresh grafts. There were somewhat lower rates of chronic GVHD (HR, 78; 95% CI, .61 to .99; P = .04) and DFS (HR for treatment failure, 1.19; 95% CI, 1.01 to 1.29; P = .04) with graft cryopreservation that were of marginal statistical significance after adjusting for multiple comparisons. Overall, our data indicate that graft cryopreservation does not significantly delay hematopoietic recovery, increase the risk of acute GVHD or NRM, or decrease OS after allo-HCT using ptCY.

Hematopoietic cell transplantation (HCT) is a well-established treatment to control and/or cure many malignant and nonmalignant diseases involving the hematopoietic system and some solid tumors. We report information about HCT procedures performed in the United States in 2018 and analyze trends and outcomes of HCT as reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). Overall, compared with 2017, the number of allogeneic HCTs performed in the United States increased by 1%, and the number of autologous HCTs decreased by 5%. Key findings are fewer autologous HCTs performed for non-Hodgkin lymphoma and increasing numbers of haploidentical HCTs, nearly all of which use post-transplantation cyclophosphamide for graft-versus-host disease prophylaxis. There is a continuing increase in HCT in adults age >70 years, particularly for acute myelogenous leukemia and myelodysplastic syndromes. Survival rates by disease, disease stage, donor type, and age are presented. This report, prepared annually by the CIBMTR, provides a snapshot of current transplant activity in the United States.

With the COVID-19 pandemic and the ensuing barriers to the collection and transport of donor cells, it is often necessary to collect and cryopreserve grafts before initiation of transplantation conditioning. The effect on transplantation outcomes in nonmalignant disease is unknown. This analysis examined the effect of cryopreservation of related and unrelated donor grafts for transplantation for severe aplastic anemia in the United States during 2013 to 2019. Included are 52 recipients of cryopreserved grafts who were matched for age, donor type, and graft type to 194 recipients who received noncryopreserved grafts. Marginal Cox regression models were built to study the effect of cryopreservation and other risk factors associated with outcomes. We recorded higher 1-year rates of graft failure (hazard ratio [HR], 2.26; 95% confidence interval, 1.17 to 4.35; P = .01) and of 1-year overall mortality (HR, 3.13; 95% CI, 1.60 to 6.11; P = .0008) after transplantation of cryopreserved compared with noncryopreserved grafts, with adjustment for sex, performance score, comorbidity, cytomegalovirus serostatus, and ABO blood group match. The incidence of acute and chronic graft-versus-host disease did not differ between the 2 groups. Adjusted probabilities of 1-year survival were 73% (95% CI, 60% to 84%) in the cryopreserved graft group and 91% (95% CI, 86% to 94%) in the noncryopreserved graft group. These data support the use of noncryopreserved grafts whenever possible in patients with severe aplastic anemia.

RESUMO
No standardized guidelines exist for infectious prophylaxis following pediatric auto-HSCT. We hypothesized significant variation in clinical practice. Thirty-three Pediatric Transplant and Cell Therapy Consortium centers completed a survey to assess institutional management. The majority utilize viral (91%) and fungal prophylaxis (94%), but duration varies. Bacterial prophylaxis during neutropenia is instituted by 42%. Our study demonstrates marked practice variability in infectious prophylaxis across centers. Additional research is needed to address patterns of infectious complications and to develop meaningful clinical practice guidelines for pediatric auto-HSCT.
