RESUMEN

OBJECTIVE: We aim to describe neonatal respiratory outcomes following previable preterm premature rupture of membranes(PPROM) when gentle ventilation is utilized. We also report maternal morbidity and mortality. STUDY DESIGN: This is a retrospective single-center cohort study of infants delivered between 2016 and 2020 that included infants born at ≥23 weeks without major congenital anomaly after a pregnancy complicated with PPROM before 23 weeks gestation. Statistical analysis utilized unpaired Student's t-test or Mann-Whitney U-test when appropriate. RESULTS: 35 infants from 33 pregnancies were included. 91.4% of infants survived until discharge and 12.1% developed Bronchopulmonary Dysplasia (BPD). Those who developed BPD had significantly lower amniotic fluid levels prior to delivery (p < 0.05). There was no significant maternal morbidity or mortality in this cohort. CONCLUSION: This cohort had high survival and low rates of respiratory morbidities. This suggests the use of gentle ventilation might be the optimal strategy for patients born after previable PPROM.

RESUMEN

BACKGROUND: There is little research investigating the subjective experiences of parenting young children while living in poverty and experiencing financial strain using qualitative methodologies. Therefore, the objective of this study was to employ a qualitative approach to provide a nuanced and balanced view on the topic of parenting young children under financial strain in the Canadian context. METHODS: We conducted a qualitative study using semi-structured interviews between July and August 2021 in Kingston, Ontario, Canada. Sixteen participants aged 20-39 self-identified as living under financial strain while parenting a child aged 2-5 years. A qualitative inductive thematic analysis was undertaken with a focus on describing the contents of the data. RESULTS: Four major themes emerged from the data: experience of being a parent, impact of financial strain on the family unit, impact of financial strain on the children, and impact of financial strain on the parent. Numerous deleterious physical, mental, and material impacts on the family unit and parent were identified, however parent-perceived impacts of financial strain on their children were minimal. Parents described striking levels of resourcefulness and resiliency in providing the necessities for their families, absorbing the most significant impacts of financial strain through the phenomenon of self-sacrifice. CONCLUSION: The impacts of financial strain on families with young children are far reaching. Further research into the impacts of self-sacrifice on parents experiencing financial strain are needed to better understand this issue, and to inform social programming and resources that could help alleviate the deleterious impacts of poverty on parent mental, social, and physical health.

RESUMEN

Low health literacy (LHL) significantly impacts patients' ability to participate actively in their healthcare. Registered nurses (RNs) play a crucial role in identifying LHL and addressing patient knowledge gaps and skill deficits. This correlational study examined the relationship between RNs' predictions of patients' health literacy levels (HLL) and the actual HLL of a predominately Hispanic patient population. In addition, personal factors (i.e., demographics) were analyzed to determine their influence on the nurse's predictions and patients' HLL. Data were collected from 84 participant patient-nurse couplets admitted to a medical-surgical unit in a rural setting located on the United States-Mexico border. In addition to demographic information collected via survey, RNs were asked to predict their patient's health literacy abilities while the Newest Vital Sign, a health literacy assessment tool, was deployed to determine the actual HLL of patients participating in the study. Data were analyzed using descriptive statistics, t-tests, and chi-square tests while a Spearman correlational model was used to examine the relationship between predicted HLL and actual HLL. Finally, a logistic regression model was used to analyze the relationship between personal factors and HL data for RNs and patients. Analysis of the data revealed that RNs consistently overestimated patients' abilities, as evidenced by the disparity between patients' actual HLL (mean 1.71) and predicted HLL (mean 4.26) by RNs, with a moderately strong positive relationship (rs = .418). Notably, higher academic preparation and years of experience did not enhance the RNs' ability to identify LHL while the highest level of education completed was the only statistically significant predictor of adequate health literacy in the patient population sampled. These findings emphasize the need to prioritize effective health literacy education in RN academic preparation and clinical practice to support the detection of LHL when a standardized health literacy assessment tool is not utilized in the clinical setting. By recognizing the presence of LHL, healthcare professionals can better support patients' needs and bridge the knowledge gap, ultimately improving patient outcomes.

RESUMEN

Calcineurin inhibitor pain syndrome (CIPS) is a rare complication of graft-vs-host disease prophylaxis following allogeneic hematopoietic cell transplant (alloHCT). CIPS presents as severe bilateral lower extremity pain, and the incidence, risk factors, and management of CIPS are poorly characterized.This is a single center retrospective study of patients who received tacrolimus (TAC) following alloHCT to describe the characteristics and management of CIPS and compare to a cohort who did not develop CIPS.Fifteen of 585 alloHCT patients (2.6%) developed CIPS at a median of 5 days following TAC initiation and a median level of 10.5 ng/mL. Severe bilateral foot, ankle, or leg pain were the primary symptoms. Patients with CIPS were younger and more frequently received myeloablative conditioning and total body irradiation compared to patients without CIPS. Analgesic regimens included dihydropyridine calcium channel blockers, gabapentinoids, topical diclofenac, and opioids.Clinicians should be aware of this uncommon but severe adverse effect.

RESUMEN

This consensus document for the performance of Cardiovascular Computed Tomography (CCT) to guide intervention in the right ventricular outflow tract (RVOT) in patients with congenital disease (CHD) was developed collaboratively by pediatric and adult interventionalists, surgeons and cardiac imagers with expertise specific to this patient subset. The document summarizes definitions of RVOT dysfunction as assessed by multi-modality imaging techniques and reviews existing consensus statements and guideline documents pertaining to indications for intervention. In the context of this background information, recommendations for CCT scan acquisition and a standardized approach for reporting prior to surgical or transcatheter pulmonary valve replacement are proposed and presented. It is the first Imaging for Intervention collaboration for CHD patients and encompasses imaging and reporting recommendations prior to both surgical and percutaneous pulmonary valve replacement.

RESUMEN

Background: Although prostate cancer patients initially respond to androgen deprivation therapy, most patients progress to a resistant phenotype. Castration resistance is due, in part, to intratumoral and/or adrenal synthesis of androgens, overexpression or mutation of the androgen receptor (AR), stabilization of AR by chaperones, and ligand-independent activation of AR. Increasing evidence also links disruption of calcium homeostasis to progression of prostate cancer. Our previous study shows that heavy metal cadmium activates the AR through a ligand-independent mechanism. Cadmium mimics calcium in biological systems due to their similar ionic charge and radius. This study determines whether calcium activates AR and whether first- and second-generation antiandrogens block the ability of calcium to activate the receptor. Methods: The expression of androgen-responsive genes and calcium channels was measured in prostate cells using a quantitative real-time polymerase chain reaction assay. Cell growth was measured. Results: To ask whether calcium activates AR, prostate cells were treated with calcium in the absence and presence of the first-generation antiandrogens hydroxyflutamide and bicalutamide and the second-generation antiandrogen enzalutamide, and the expression of androgen-responsive genes and cell growth was measured. In the normal PWR-1E cells and HEK293T cells transiently expressing AR, treatment with calcium increased the expression of androgen-responsive genes by approximately 3-fold. The increase was blocked by enzalutamide but was not consistently blocked by the first-generation antiandrogens. In LNCaP cells which contain a mutant AR, treatment with calcium also increased the expression of androgen-responsive genes by approximately 3-fold, and the increase was more effectively blocked by enzalutamide than by hydroxyflutamide or bicalutamide. Treatment with calcium also increased cell growth that was blocked by enzalutamide. To ask whether dysregulation of calcium channels is associated with castration resistance, calcium channels were measured in the normal PWR-1E prostate cells, the hormone-responsive LNCaP cells, and the castration-resistant VCaP and 22RV1 cells. Compared to normal prostate cells, the hormone-responsive and hormone-resistant cells overexpressed several calcium channels. Conclusions: The results of this study show that calcium activates AR and increases cell growth and that calcium channels are overexpressed in hormone-responsive and hormone-resistant prostate cancer cells. Taken together, the results suggest a novel role of calcium in the castration-resistant phenotype.

RESUMEN

PURPOSE: To describe a patient with acute myelogenous leukemia who presented with a recurrent, bilateral, outer retinopathy, before and after consolidative peripheral blood stem cell transplantation complicated by chronic graft-versus-host disease. METHODS: This is a retrospective review of records from a 23-year-old woman with acute myelogenous leukemia who underwent comprehensive ophthalmic evaluations for over a year including chromatic perimetry and multifocal electroretinograms, imaging with spectral domain optical coherence tomography, near-infrared and short-wavelength fundus reflectance and autofluorescence, fluorescein and optical coherence tomography angiography. RESULTS: The patient presented with recurrent, unilateral paracentral scotomas. There was localized loss of inner segment ellipsoid (EZ) and photoreceptor outer segment signals (IZ) in the pericentral retina of both eyes co-localizing with hyperreflective lesions on near-infrared reflectance. She subsequently lost vision (visual acuity = 20/200) in the right eye a year after consolidative peripheral blood stem cell transplantation complicated by steroid-resistant-chronic graft-versus-host disease. There was loss of the EZ and IZ signals corresponding to a dense central cone scotoma and multifocal electroretinograms depression. Near-infrared autofluorescence, fluorescein and optical coherence tomography angiography were within normal limits. Visual acuity (20/20) and retinal sensitivities improved with restoration of the EZ/IZ signals after oral prednisone and intravenous rituximab, but left a residual photoreceptor loss and paracentral scotoma. CONCLUSION: We propose that an immune-mediated microangiopathy may explain the protracted, recurrent course of primary photoreceptor abnormalities in our patient, which was further complicated by manifestations of chronic graft-versus-host disease following consolidative peripheral blood stem cell transplantation. Outer retinal findings previously documented in leukemia may be explained by a similar mechanism.

RESUMEN

The estrogen receptor alpha (ERα) is a steroid receptor that is pivotal in the initiation and progression of most breast cancers. ERα regulates gene transcription through recruitment of essential coregulators, including the steroid receptor coactivator AIB1 (Amplified in Breast Cancer 1). AIB1 itself is an oncogene that is overexpressed in a subset of breast cancers and is known to play a role in tumor progression and resistance to endocrine therapy through multiple mechanisms. Here we review the normal and pathological functions of AIB1 in regard to its ERα-dependent and ERα-independent actions, as well as its genomic conservation and protein evolution. We also outline the efforts to target AIB1 in the treatment of breast cancer.

RESUMEN

INTRODUCTION: Busulfan is a common component of allogeneic hematopoietic cell transplant (alloHCT) conditioning, however interpatient pharmacokinetic variability can result in enhanced toxicity or increased relapse risk. Therapeutic drug monitoring (TDM) can minimize variability, yet the optimal frequency of TDM is unknown. We compared outcomes for patients with one versus two sets of busulfan TDM during myeloablative conditioning (MAC) prior to alloHCT. METHODS: We analyzed the impact of busulfan TDM frequency and dose adjustments, with the primary outcome being relapse-free survival (RFS). Other outcomes included the incidence of acute and chronic graft versus host disease (GVHD), oral mucositis, pulmonary toxicity, sinusoidal obstruction syndrome (SOS), the cumulative incidence of relapse (CIR), and overall survival (OS). RESULTS: Twenty-two patients underwent one set of sampling while 53 patients underwent two sets. Similar baseline characteristics were observed between the groups. There were no significant differences observed in RFS by day +180 (77.3% vs. 79.2%, p = 1.0), CIR by day +180 (18.2% vs. 17.8%, p = 0.74), or OS (p = 0.73). The incidences of acute GVHD, chronic GVHD, SOS, and severe mucositis were also similar. In each group, 63% received busulfan dose adjustments after one set, with 52.8% receiving further dose adjustments following the second set. CONCLUSION: We observed no significant difference in alloHCT outcomes between patients who underwent one versus two sets of busulfan TDM sampling, suggesting that a single-time TDM and dose adjustment may be adequate to maximize outcomes after MAC alloHCT.

RESUMEN

Intensive chemotherapy with cytarabine and anthracycline (7&3) remains the standard therapy for patients medically fit for induction, but the assessment of fitness remains controversial. Venetoclax and hypomethylating agent (ven/HMA) combination therapy has improved outcomes in unfit patients but no prospective study has assessed ven/HMA versus 7&3 as initial therapy in older, fit patients. Given no studies and expectation of ven/HMA use in patients outside of trial criteria, we evaluated retrospective outcomes among newly diagnosed patients. A nationwide electronic health record (EHR)-derived database and the University of Pennsylvania EHR identified 312 patients receiving 7&3 and 488 receiving ven/HMA who were 60-75 years old without history of organ failure. Ven/HMA patients were older and more likely to have secondary AML, adverse cytogenetics, and adverse mutations. Median overall survival (OS) for patients receiving intensive chemotherapy was 22 versus 10 months for ven/HMA (HR 0.53, 95% CI 0.40-0.60). Controlling for measured baseline characteristic imbalances reduced survival advantage by half (HR 0.71, 95% CI 0.53-0.94). A sub-group of patients with equipoise, likelihood at least 30%-70% of receiving either treatment, had similar OS outcomes (HR 1.10, 95% CI 0.75-1.6). Regarding safety outcomes, 60-day mortality was higher for ven/HMA (15% vs. 6% at 60 days) despite higher documented infections and febrile neutropenia for 7&3. In this multicenter real-word dataset, patients selected for intensive chemotherapy had superior OS but a large group had similar outcomes with ven/HMA. Prospective randomized studies, controlling for both measured and unmeasured confounders, must confirm this outcome.

RESUMEN

BACKGROUND/AIMS: Data are limited on the frequency of 'consensus decisions' between sub-specialists attending a neurovascular multidisciplinary meeting (MDM) regarding management of patients with extracranial carotid/vertebral stenoses and post-MDM 'adherence' to such advice. METHODS: This prospective audit/quality improvement project collated prospectively-recorded data from a weekly Neurovascular/Stroke Centre MDM documenting the proportion of extracranial carotid/vertebral stenosis patients in whom 'consensus management decisions' were reached by neurologists, vascular surgeons, stroke physicians-geriatricians and neuroradiologists. Adherence to MDM advice was analysed in asymptomatic carotid stenosis (ACS), symptomatic carotid stenosis (SCS), 'indeterminate symptomatic status stenosis' (ISS) and vertebral artery stenosis (VAS) patients, including intervals between index event to MDM + / - intervention. RESULTS: One hundred fifteen patients were discussed: 108 with carotid stenosis and 7 with VAS. Consensus regarding management was noted in 96.5% (111/115): 100% with ACS and VAS, 96.2% with SCS and 92.9% with ISS. Adherence to MDM management advice was 96.4% (107/111): 100% in ACS, ISS and VAS patients; 92% (46/50) in SCS patients. The median interval from index symptoms to revascularisation in 50-99% SCS patients was 12.5 days (IQR: 9-18.3 days; N = 26), with a median interval from MDM to revascularisation of 5.5 days (IQR: 1-7 days). Thirty patients underwent revascularisation. Two out of twenty-nine patients (6.9%) with either SCS or ISS had a peri-procedural ipsilateral ischaemic stroke, with no further strokes/deaths during 3-months follow-up. CONCLUSIONS: The high frequency of inter-specialty consensus regarding management and adherence to proposed treatment supports a collaborative/multidisciplinary model of care in patients with extracranial arterial stenoses. Service development should aim to shorten times between MDM discussion-intervention and optimise prevention of stroke/death.

RESUMEN

(1) Background: Self-management is advocated as a feasible, effective intervention to support individuals to actively manage the impact of illness and live healthier lives. We sought to evaluate a piloted self-management model, SET for Health, tailored for individuals living with schizophrenia embedded within ambulatory case management. (2) Methods: A mixed-methods design engaged 40 adults living with schizophrenia in the SET for Health protocol. Functional and symptomatic outcomes were measured by self-report and clinician ratings at baseline and completion of self-management plans, on average one year later. Semi-structured qualitative client interviews invited evaluations of personal experiences with the intervention. (3) Results: Significant improvements were found concerning client illness severity, social and occupational functioning, illness management and functional recovery with reductions in emergency visits and days in hospital. Clients endorsed the value of the intervention. Baseline clinical characteristics did not predict who benefited. Participation contributed to motivational gains and quality of life. (4) Conclusions: Results confirmed self-management support embedded within traditional case management improved clients' clinical and functional status, and contributed to quality of life. Clients engaged in their recovery and actively used self-management strategies. Self-management can be successfully adopted by clients with schizophrenia regardless of age, gender, education, illness severity or duration.

RESUMEN

OBJECTIVES: To determine the safety and feasibility of over-expansion of right ventricle to pulmonary artery conduits during transcatheter pulmonary valve placement. BACKGROUND: Transcatheter pulmonary valve placement is an alternative to surgical pulmonary valve replacement. Traditionally, it was thought to be unsafe to expand a conduit to >110% of its original size. METHODS: This retrospective cohort study from two centers includes patients with right ventricle to pulmonary artery conduits with attempted transcatheter pulmonary valve placement from 2010 to 2017. Demographic, procedural, echocardiographic and follow-up data, and complications were evaluated in control and overdilation (to >110% original conduit size) groups. RESULTS: One hundred and seventy-two patients (51 overdilation and 121 control) had attempted transcatheter pulmonary valve placement (98% successful). The overdilation group was younger (11.2 versus 16.7 years, p < 0.001) with smaller conduits (15 versus 22 mm, p < 0.001); however, the final valve size was not significantly different (19.7 versus 20.2 mm, p = 0.2). Baseline peak echocardiographic gradient was no different (51.8 versus 55.6 mmHg, p = 0.3). Procedural complications were more frequent in overdilation (18%) than control (7%) groups (most successfully addressed during the procedure). One patient from each group required urgent surgical intervention, with no procedural mortality. Follow-up echocardiographic peak gradients were similar (24.1 versus 26 mmHg, p = 0.5). CONCLUSIONS: Over-expansion of right ventricle to pulmonary artery conduits during transcatheter pulmonary valve placement can be performed successfully. Procedural complications are more frequent with conduit overdilation, but there was no difference in the rate of life-threatening complications. There was no difference in valve function at most recent follow-up, and no difference in rate of reintervention. The long-term outcomes of transcatheter pulmonary valve placement with conduit over-expansion requires further study.

RESUMEN

BACKGROUND: Ventricular arrhythmia incidence in children and adolescents undergoing transcatheter pulmonary valve replacement (TPVR) within the native right ventricular outflow tract (nRVOT) is unknown. We sought to describe the incidence, severity, and duration of ventricular arrhythmias and identify associated risk factors in this population. METHODS: This was a retrospective cohort study of 78 patients <21 years of age who underwent TPVR within the nRVOT. Patients were excluded for pre-existing ventricular arrhythmia or antiarrhythmic use. Study variables included surgical history, valve replacement indication, valve type/size, and ventricular arrhythmia. Univariable logistic regression models were used to evaluate factors associated with ventricular arrhythmias, followed by subset analyses. RESULTS: Nonsustained ventricular arrhythmia occurred in 26/78 patients (33.3%). The median age at the procedure was 10.3 years (interquartle range [IQR]: 6.5, 12.8). Compared with other nRVOT types, surgical repair with transannular patch was protective against ventricular arrhythmia incidence: odds ratio (OR): 0.35 (95% confidence interval [CI], 0.13-0.95). Patient weight, valve type/size, number of prestents, and degree of stent extension into the RVOT were not associated with ventricular arrhythmia occurrence. Beta blocker was started in 16/26 (61.5%) patients with ventricular arrhythmia. One additional patient was lost to follow-up. The median beta blocker duration was 46 days (IQR 42, 102). Beta blocker was discontinued in 10 patients by 8-week follow-up and in the remaining four by 9 months. CONCLUSIONS: Though common after balloon-expandable TPVR within the nRVOT, ventricular arrhythmias were benign and transient. Antiarrhythmic medications were successfully discontinued in the majority at 6- to 8-week follow-up, and in all patients by 20 months.

RESUMEN

INTRODUCTION: Self-management support for schizophrenia has become expected practice leaving organisations to find ways for feasible implementation. Self-management support involves a foundational cultural shift for traditional disease-based services, new ways of clients-providers working together, coupled with delivering a portfolio of tools and techniques. A new model of self-management support embedded into traditional case management services, called SET for Health (Self-management Engaging Together for Health),  was designed and tailored to make such services meaningfully accessible to clients of a tertiary care centre. This paper describes the proof of concept demonstration efforts, the successes/challenges, and initial organisational changes. METHOD: An integrated knowledge translation approach was selected as a means to foster organisational change grounded in users' daily realities. Piloting the model in two community case management programmes, we asked two questions: Can a model of self-management support be embedded in existing case management and delivered within routine specialised mental health services? What organisational changes support implementation? RESULTS: Fifty-one clients were enroled. Indicators of feasible delivery included 72.5% completion of self-management plans in a diverse sample, exceeding the 44% set minimum; and an attrition rate of 21.6%, less than 51% set maximum. Through an iterative evaluation process, the innovation evolved to a targeted hybrid approach revolving around client goals and a core set of co-created reference tools, supplemental tools and resources. Operationalisation by use of tools was implemented to create spaces for client-provider collaborations. Monitoring of organisational changes identified realignment of practices. Changes were made to procedures and operations to further spread and sustain the model. CONCLUSION: This study demonstrated how self-management support can be implemented, within existing resources, for routine delivery of specialised services for individuals living with schizophrenia. The model holds promise as a hybrid option for supporting clients to manage their own health and wellness.

RESUMEN

INTRODUCTION: This article describes the planning and development of a novel self-management support protocol, self-management engaging together (SET) for Health, purposefully designed and embedded within traditional case management services to be accessible to people living with schizophrenia and comorbidities. Drawing on established self-management principles, SET for Health was codesigned by researchers, healthcare providers and clients, to create a practical and meaningful intervention to support the target group to manage their own health and wellness. Decision making is described behind tailoring the self-management innovation to meet the needs of an at risk, disadvantaged group served by tertiary, public health care in Canada. METHOD: This integrated knowledge translation (IKT) study used a descriptive approach to document the process of planning and operationalizing the SET for Health intervention as a part of routine care in two community-based teams providing predominantly schizophrenia services. Diffusion of innovations literature informed planning. The setting was strategically prepared for organizational change. A situational assessment and theoretical frameworks identified contextual elements to be addressed. Existing established self-management approaches for mental illness were appraised. RESULTS: When a review of established approaches revealed incongruence with the aims and context of service delivery, common essential elements were distilled. To facilitate collaborative client-provider self-management conversations and self-management learning opportunities, core components were operationalized by the use of tailored interactive tools. The materials coproduced by clients and providers offered joint reference tools, foundational for capacity-building and recognition of progress. CONCLUSION: Planning and developing a model of self-management support for integration into traditional schizophrenia case management services required attention to the complex social ecological nature of the treatment approach and the workplace context. Demonstration of proof of concept is described in a separate paper.

RESUMEN

The objective of the study was to explore the experience of patients who self-withdrew from their scheduled bariatric surgery (BS) after completing the lengthy multidisciplinary assessment and optimization process, and to examine how these withdrawals affect healthcare providers (HCPs) in a Bariatric Centre of Excellence (BCoE). Interviews were conducted with patients who self-withdrew, within 1 month, from scheduled BS. Additionally, a focus group with HCPs from the same BCoE was completed. The data were analysed using an inductive, emergent thematic approach with open coding in NVivo 12, with comparative analysis to identify common themes between groups. Eleven patients and 14 HCPs participated. HCPs identified several behavioural and logistical red flags among patients who self-withdrew from scheduled BS. Patients and HCPs felt the decision was appropriate, owing to a patient's lack of mental preparedness for change, social supports, or fears of postoperative complications. HCPs reported frustration and described negative impacts on clinic efficiency. Additional mental health resources for patients contemplating self-withdrawal, such as peer support, were suggested. In conclusion, a patient's decision to self-withdraw from a scheduled BS is often sudden, definite, and associated with anxiety, fear of surgical risks and post-operative complications. Additional mental health resources at a BCoE may be beneficial to support patients at risk of self-withdrawal from scheduled BS.

RESUMEN

Patients with refractory or relapsed and refractory myeloid malignancies have a poor prognosis. Allogeneic hematopoietic cell transplantation (HCT) with myeloablative conditioning (MAC) in patients with active, chemotherapy-refractory myeloid disease is historically associated with high rates of relapse and nonrelapse mortality (NRM). A MAC regimen combining clofarabine with busulfan (Clo/Bu4) has been reported to exhibit antileukemic activity with acceptable toxicity in patients age ≤70 years. Here we describe the clinical outcomes of a real-world population of patients with active myeloid malignancies undergoing allogeneic HCT with Clo/Bu4 MAC. In a single-center retrospective descriptive analysis, we identified patients who underwent HCT for myeloid malignancies not in remission using Clo/Bu4 MAC between 2012 and 2020. We report event-free survival (EFS) and overall survival (OS), cumulative incidences of relapse and NRM, and the incidence and severity of acute and chronic graft-versus-host disease (GVHD). We identified 69 patients with a median age of 60 years (range, 22 to 70 years). Most patients had relapsed/refractory or primary refractory acute myelogenous leukemia (AML; n = 55) or refractory myelodysplastic syndrome (MDS; n = 12); 1 patient had chronic myelogenous leukemia, and 1 patient had a blastic plasmacytoid dendritic cell neoplasm. Fifty patients (72.5%) had complete remission at day 100 post-transplantation. Two-year EFS and OS were 30% (95% confidence interval [CI], 20% to 44%) and 40% (95% CI, 29% to 54%), respectively. Patients with AML had a 2-year EFS and OS of 28% (95% CI, 18% to 44%) and 38% (95% CI, 27% to 54%), respectively; those with MDS had a 2-year EFS and OS of 47% (95% CI, 25% to 88%) and 56% (95% CI, 33% to 94%), respectively. The cumulative incidence of relapse at 2 years was 39% (95% CI, 27% to 51%) for all patients, including 45% (95% CI, 31% to 58%) in the patients with AML and 18% (95% CI, 2% to 45%) in those with MDS. NRM at 2 years was 31% (95% CI, 20% to 42%), including 27% (95% CI, 15% to 39%) in patients with AML and 35% (95% CI, 10% to 63%) in those with MDS. The total incidence of acute GVHD (aGVHD) of any severity was 80%, and the incidence of grade III-IV aGVHD was 22%. In patients who achieved remission, those who required systemic immunosuppression for aGVHD (58%) had poorer 2-year EFS (29% versus 54%; P = .05) and 2-year OS (39% versus 70%; P = .04) compared to those who did not. The 2-year cumulative incidence of chronic GVHD was 44% (95% CI, 28% to 58%). Clo/Bu4 MAC followed by allogeneic HCT for patients with active myeloid malignancies is an effective transplantation strategy for patients up to age 70, particularly those with advanced MDS. The high incidence of and poor outcomes associated with aGVHD highlight the importance of optimizing preventative strategies.
