Ongoing genome doubling promotes evolvability and immune dysregulation in ovarian cancer.

Whole-genome doubling (WGD) is a critical driver of tumor development and is linked to drug resistance and metastasis in solid malignancies. Here, we demonstrate that WGD is an ongoing mutational process in tumor evolution. Using single-cell whole-genome sequencing, we measured and modeled how WGD events are distributed across cellular populations within tumors and associated WGD dynamics with properties of genome diversification and phenotypic consequences of innate immunity. We studied WGD evolution in 65 high-grade serous ovarian cancer (HGSOC) tissue samples from 40 patients, yielding 29,481 tumor cell genomes. We found near-ubiquitous evidence of WGD as an ongoing mutational process promoting cell-cell diversity, high rates of chromosomal missegregation, and consequent micronucleation. Using a novel mutation-based WGD timing method, doubleTime , we delineated specific modes by which WGD can drive tumor evolution: (i) unitary evolutionary origin followed by significant diversification, (ii) independent WGD events on a pre-existing background of copy number diversity, and (iii) evolutionarily late clonal expansions of WGD populations. Additionally, through integrated single-cell RNA sequencing and high-resolution immunofluorescence microscopy, we found that inflammatory signaling and cGAS-STING pathway activation result from ongoing chromosomal instability and are restricted to tumors that remain predominantly diploid. This contrasted with predominantly WGD tumors, which exhibited significant quiescent and immunosuppressive phenotypic states. Together, these findings establish WGD as an evolutionarily 'active' mutational process that promotes evolvability and dysregulated immunity in late stage ovarian cancer.

Individualizing busulfan dose in specific populations and evaluating the risk of pharmacokinetic drug-drug interactions.

INTRODUCTION: Busulfan is an alkylating agent widely used in the conditioning of hematopoietic stem cell transplantation possessing a complex metabolism and a large interindividual and intra-individual variability, especially in children. Combined with the strong rationale of busulfan PK/PD relationships, factors altering its clearance (e.g. weight, age, and GST-A genetic polymorphism mainly) can also affect clinical outcomes. AREAS COVERED: This review aims to provide an overview of the current knowledge on busulfan pharmacokinetics, its pharmacokinetics variabilities in pediatric populations, drug-drug interactions (DDI), and their consequences regarding dose individualization. This review was based on medical literature up until October 2021. EXPERT OPINION: To ensure effective busulfan exposure in pediatrics, different weight-based nomograms have been established to determine busulfan dosage and provided improved results (65-80% of patients correctly exposed). In addition to nomograms, therapeutic drug monitoring (TDM) of busulfan measuring plasmatic concentrations to estimate busulfan pharmacokinetic parameters can be used. TDM is now widely carried out in routine practices and aims to ensure the targeting of the reported therapeutic windows by individualizing busulfan dosing based on the clearance estimations from a previous dose.

Advances in the Treatment of Hairy Cell Leukemia Variant.

OPINION STATEMENT: Hairy cell leukemia variant (HCL-V) is a rare B cell lymphoproliferative disorder with a clinical-pathological distinction from the classic form of hairy cell leukemia (HCL-C). HCL-V is more aggressive in nature, has a higher tendency to be refractory to conventional purine analog pharmacotherapies, and leads to a poorer prognosis. Hence, these differing features bring paramount importance to the diagnosis and management of HCL-V. While there is no genetic mutation diagnostic of HCL-V, genetic profiling efforts have identified potential therapeutic targets (i.e., MAP2K1, KDM6A, CREBBP, ARID1A, CCND3, U2AF1, KMT2C) and yielded prognostic markers (i.e., IGHV4-34 rearrangements). To date, combination chemoimmunotherapies, such as cladribine and rituximab, have shown the best results in HCL-V. Future directions include targeted therapies such as moxetumomab pasudotox, ibrutinib, trametinib, and binimetinib and potentially anti-CD22 chimeric antigen receptor T cell therapy. The purpose of this review is to provide an outline of the diagnostic approach and an update on the therapeutic advancements in HCL-V.

Stabilization of ß-catenin upon B-cell receptor signaling promotes NF-kB target genes transcription in mantle cell lymphoma.

B-cell receptor (BCR) signaling pathways and interactions with the tumor microenvironment account for mantle cell lymphoma (MCL) cells survival in lymphoid organs. In several MCL cases, the WNT/ß-catenin canonical pathway is activated and ß-catenin accumulates into the nucleus. As both BCR and ß-catenin are important mediators of cell survival and interaction with the microenvironment, we investigated the crosstalk between BCR and WNT/ß-catenin signaling and analyzed their impact on cellular homeostasis as well as their targeting by specific inhibitors. ß-catenin was detected in all leukemic MCL samples and its level of expression rapidly increased upon BCR stimulation. This stabilization was hampered by the BCR-pathway inhibitor Ibrutinib, supporting ß-catenin as an effector of the BCR signaling. In parallel, MCL cells as compared with normal B cells expressed elevated levels of WNT16, a NF-κB target gene. Its expression increased further upon BCR stimulation to participate to the stabilization of ß-catenin. Upon BCR stimulation, ß-catenin translocated into the nucleus but did not induce a Wnt-like transcriptional response, i.e., TCF/LEF dependent. ß-catenin rather participated to the regulation of NF-κB transcriptional targets, such as IL6, IL8, and IL1. Oligo pull down and chromatin immunoprecipitation experiments demonstrated that ß-catenin is part of a protein complex that binds the NF-κB DNA consensus sequence, strengthening the idea of an association between the two proteins. An inhibitor targeting ß-catenin transcriptional interactions hindered both NF-κB DNA recruitment and induced primary MCL cells apoptosis. Thus, ß-catenin likely represents another player through which BCR signaling impacts on MCL cell survival.

Caregiver Patient Reported Outcomes Measurement Information System (PROMIS) profiles in patients undergoing total joint arthroplasty and spine surgery: a prospective observational cohort study.

BACKGROUND/OBJECTIVE: The role of caregiver psychosocial characteristics and their relation to postsurgical caregiving capability remains unclear. The objective of this study was to explore caregiver psychosocial variables following surgery of patients undergoing total joint arthroplasty and spine surgery. METHODS: A prospective observational study was conducted where questionnaires were administered to caregivers preoperatively and 1 week/2 weeks/1 month postoperatively. Measures included demographics, caregiver activities and National Institutes of Health Patient Reported Outcomes Measurement Information System (NIH PROMIS) item banks. Bivariate analysis assessed differences between participants reporting baseline pain and those reporting no baseline pain. Generalized estimating equation models examined PROMIS T-scores across time. RESULTS: 190 caregivers were enrolled and completed surveys. 18% of caregivers reported experiencing a painful condition where they experienced pain during most days of the week. Across all time points, the majority of caregivers reported no worse than mild impairment across PROMIS scores. Compared with baseline, caregivers reported lower PROMIS satisfaction with social roles across all postoperative time points (p<0.001) and higher depression and fatigue at postoperative day 7 (p=0.002) and 14 (p=0.006). PROMIS sleep disturbance was only higher at day 7 (p=0.01). Caregivers reporting a baseline pain condition reported PROMIS scores indicative of higher anxiety (p=0.02), depression (p=0.003), sleep disturbances (p<0.001) and fatigue (p<0.001) and lower levels of satisfaction with social roles (p=0.002) compared with those caregivers without baseline pain. CONCLUSION: While there were transient worsening in PROMIS scores, it is unclear whether these were clinically meaningful. Postsurgical caregivers reporting baseline pain were characterized by worse functioning across all PROMIS scales.

Gain of the short arm of chromosome 2 (2p gain) has a significant role in drug-resistant chronic lymphocytic leukemia.

The different types of drug resistance encountered in chronic lymphocytic leukemia (CLL) cannot be fully accounted for by the 17p deletion (and/or TP53 mutation), a complex karyotype (CK), immunoglobulin heavy-chain variable region genes (IGHV) status and gene mutations. Hence, we sought to assess the associations between recurrent genomic abnormalities in CLL and the disease's development and outcome. To this end, we analyzed 64 samples from patients with CLL and gain of the short arm of chromosome 2 (2p+), which is frequent in late-stage and relapsed/refractory CLL. We found that fludarabine/cyclophosphamide/rituximab (a common first-line treatment in CLL) is not effective in removing the 2p+ clone - even in samples lacking a CK, the 17p deletion or unmutated IGHV. Our results suggest strongly that patients with CLL should be screened for 2p+ (using karyotyping and fluorescence in situ hybridization) before a treatment option is chosen. Longer follow-up is now required to evaluate bendamustine-rituximab, ibrutinib, and idelalisib-rituximab treatments.

Feasibility of App-Based Postsurgical Assessment of Pain, Pain Impact, and Regional Anesthesia Effects: A Pilot Randomized Controlled Trial.

OBJECTIVE: Postsurgical follow-up calls enable nurses to assess a patient's condition, provide tailored education, and improve the patient's experience. Despite the benefits, barriers to phone-based assessments may include patient nonresponse and lack of time due to demanding clinical schedules. The purpose of this trial was to examine the feasibility and utility of a smartphone app, mCare, for assessing pain, pain impact, and peripheral nerve block effects in patients. DESIGN: Pilot randomized control trial. SETTING AND PATIENTS: Eligible patients at a military treatment facility undergoing same-day surgery were randomized to the mCare group (N = 24) or the standard-of-care telephone (N = 26) group. RESULTS: Outcomes included initial response (assessment completion) rates and participant and nurse satisfaction. There were no differences in the response rates upon initial contact attempt, and patients in both groups reported similar levels of satisfaction and convenience. Nurses reported greater satisfaction with the app compared with standard-of-care telephone calls. CONCLUSIONS: Before wider implementation, further considerations of app-based assessment need to be fully explored.

The Poly(ADP-ribose) Polymerase Enzyme Tankyrase Antagonizes Activity of the ß-Catenin Destruction Complex through ADP-ribosylation of Axin and APC2.

Most colon cancer cases are initiated by truncating mutations in the tumor suppressor, adenomatous polyposis coli (APC). APC is a critical negative regulator of the Wnt signaling pathway that participates in a multi-protein "destruction complex" to target the key effector protein ß-catenin for ubiquitin-mediated proteolysis. Prior work has established that the poly(ADP-ribose) polymerase (PARP) enzyme Tankyrase (TNKS) antagonizes destruction complex activity by promoting degradation of the scaffold protein Axin, and recent work suggests that TNKS inhibition is a promising cancer therapy. We performed a yeast two-hybrid (Y2H) screen and uncovered TNKS as a putative binding partner of Drosophila APC2, suggesting that TNKS may play multiple roles in destruction complex regulation. We find that TNKS binds a C-terminal RPQPSG motif in Drosophila APC2, and that this motif is conserved in human APC2, but not human APC1. In addition, we find that APC2 can recruit TNKS into the ß-catenin destruction complex, placing the APC2/TNKS interaction at the correct intracellular location to regulate ß-catenin proteolysis. We further show that TNKS directly PARylates both Drosophila Axin and APC2, but that PARylation does not globally regulate APC2 protein levels as it does for Axin. Moreover, TNKS inhibition in colon cancer cells decreases ß-catenin signaling, which we find cannot be explained solely through Axin stabilization. Instead, our findings suggest that TNKS regulates destruction complex activity at the level of both Axin and APC2, providing further mechanistic insight into TNKS inhibition as a potential Wnt pathway cancer therapy.

IFITM-2 and IFITM-3 but not IFITM-1 restrict Rift Valley fever virus.

We show that interferon-induced transmembrane protein 1 (IFITM-1), IFITM-2, and IFITM-3 exhibit a broad spectrum of antiviral activity against several members of the Bunyaviridae family, including Rift Valley fever virus (RVFV), La Crosse virus, Andes virus, and Hantaan virus, all of which can cause severe disease in humans and animals. We found that RVFV was restricted by IFITM-2 and -3 but not by IFITM-1, whereas the remaining viruses were equally restricted by all IFITMs. Indeed, at low doses of alpha interferon (IFN-α), IFITM-2 and -3 mediated more than half of the antiviral activity of IFN-α against RVFV. IFITM-2 and -3 restricted RVFV infection mostly by preventing virus membrane fusion with endosomes, while they had no effect on virion attachment to cells, endocytosis, or viral replication kinetics. We found that large fractions of IFITM-2 and IFITM-3 occupy vesicular compartments that are distinct from the vesicles coated by IFITM-1. In addition, although overexpression of all IFITMs expanded vesicular and acidified compartments within cells, there were marked phenotypic differences among the vesicular compartments occupied by IFITMs. Collectively, our data provide new insights into the possible mechanisms by which the IFITM family members restrict distinct viruses.

Inhibition of de novo ceramide biosynthesis by FTY720 protects rat retina from light-induced degeneration.

Light-induced retinal degeneration (LIRD) in albino rats causes apoptotic photoreceptor cell death. Ceramide is a second messenger for apoptosis. We tested whether increases in ceramide mediate photoreceptor apoptosis in LIRD and if inhibition of ceramide synthesis protects the retina. Sprague-Dawley rats were exposed to 2,700 lux white light for 6 h, and the retinal levels of ceramide and its intermediary metabolites were measured by GC-MS or electrospray ionization tandem mass spectrometry. Enzymes of the de novo biosynthetic and sphingomyelinase pathways of ceramide generation were assayed, and gene expression was measured. The dosage and temporal effect of the ceramide synthase inhibitor FTY720 on the LIRD retina were measured by histological and functional analyses. Retinal ceramide levels increased coincident with the increase of dihydroceramide at various time points after light stress. Light stress in retina induces ceramide generation predominantly through the de novo pathway, which was prevented by systemic administration of FTY720 (10 mg/kg) leading to the protection of retinal structure and function. The neuroprotection of FTY720 was independent of its immunosuppressive action. We conclude that ceramide increase by de novo biosynthesis mediates photoreceptor apoptosis in the LIRD model and that inhibition of ceramide production protects the retina against light stress.

Targeting early B-cell receptor signaling induces apoptosis in leukemic mantle cell lymphoma.

BACKGROUND: We previously showed that B-cell receptor (BCR) signaling pathways are important for in vitro survival of mantle cell lymphoma (MCL) cells. To further identify early BCR-activated signaling pathways involved in MCL cell survival, we focused our study on BCR-proximal kinases such as LYN whose dysregulations could contribute to the aggressive course of MCL. METHODS: Primary MCL cells were isolated from 14 leukemic patients. Early BCR-induced genes were identified by qRT-PCR array. The basal and BCR-induced phosphorylation of LYN and JNK were evaluated by immunoblottting. Cell survival signals were evaluated by apoptosis using flow cytometry. RESULTS: We showed that LYN was constitutively phosphorylated in MCL cell lines and in 9/10 leukemic MCL cases. Treatment with dasatinib or with a specific inhibitor of Src kinases such as PP2 suppressed constitutive LYN activation and increased in vitro spontaneous apoptosis of primary MCL cells. BCR engagement resulted in an increase of LYN phosphorylation leading to activation of c-JUN NH2-terminal kinase (JNK) and over-expression of the early growth response gene-1 (EGR-1). Inhibition of JNK with SP600125 induced apoptosis and reduced level of basal and BCR-induced expression of EGR-1. Furthermore, decreasing EGR1 expression by siRNA reduced BCR-induced cell survival. Treatment with PP2 or with dasatinib suppressed BCR-induced LYN and JNK phosphorylation as well as EGR-1 upregulation and is associated with a decrease of cell survival in all cases analysed. CONCLUSIONS: This study highlights the importance of BCR signaling in MCL cell survival and points out to the efficiency of kinase inhibitors in suppressing proximal BCR signaling events and in inducing apoptosis.

Caffeic acid phenethyl ester protects 661W cells from H2O2-mediated cell death and enhances electroretinography response in dim-reared albino rats.

PURPOSE: Caffeic acid phenethyl ester (CAPE), an active component of honeybee propolis, has a wide range of beneficial properties. The purpose of this study was to test the protective role of CAPE in 661W cells (in vitro) against H(2)O(2)-mediated cell death and in albino rats (in vivo) against various light conditions. METHODS: The 661W cells were pretreated with CAPE and then stressed with H(2)O(2). Cell death was measured with lactate dehydrogenase (LDH) release assay, and mRNA and proteins were analyzed. Sprague Dawley rats were raised on either a control or CAPE (0.02%) diet and exposed to various light conditions for short or long periods. Retinal histology, mRNA, protein, lipid composition, and retinal function by electroretinography (ERG) were measured at the end of feeding. RESULTS: Pretreatment of 661W cells with CAPE reduced H(2)O(2)-mediated cell death in a dose-dependent manner and induced expression of heme oxygenase-1 (Ho1). Albino rats fed with CAPE had greater expression of Ho1 and intercellular adhesion molecule 1 (Icam1), less expression of FOS-like antigen (Fosl) and lipoxygenase 12 (Lox12) genes in the retina, less translocation of nuclear factor kappaB protein to the nucleus, and a lower molar ratio of n-3 polyunsaturated fatty acids. Further, the ERGs of the retinas of CAPE-fed rats were significantly higher than those of the control-fed rats when raised in dim light. CONCLUSIONS: CAPE can activate the antioxidative gene expression pathway in retinal cells in vitro and in vivo. Feeding CAPE to albino rats can enhance ERG responses and change the lipid profile in the rats' retinas.

Identification of an antioxidant small-molecule with broad-spectrum antiviral activity.

The highly lethal filoviruses, Ebola and Marburg cause severe hemorrhagic fever in humans and non-human primates. To date there are no licensed vaccines or therapeutics to counter these infections. Identifying novel pathways and host targets that play an essential role during infection will provide potential targets to develop therapeutics. Small molecule chemical screening for Ebola virus inhibitors resulted in identification of a compound NSC 62914. The compound was found to exhibit anti-filovirus activity in cell-based assays and in vivo protected mice following challenge with Ebola or Marburg viruses. Additionally, the compound was found to inhibit Rift Valley fever virus, Lassa virus and Venezuelan equine encephalitis virus in cell-based assays. Investigation of the mechanism of action of the compound revealed that it had antioxidant properties. Specifically, compound NSC 62914 was found to act as a scavenger of reactive oxygen species, and to up-regulate oxidative stress-induced genes. However, four known antioxidant compounds failed to inhibit filovirus infection, thus suggesting that the mechanistic basis of the antiviral function of the antioxidant NSC 62914 may involve modulation of multiple signaling pathways/targets.

Curcumin protects retinal cells from light-and oxidant stress-induced cell death.

Age-related macular degeneration (AMD) is a complex disease that has potential involvement of inflammatory and oxidative stress-related pathways in its pathogenesis. In search of effective therapeutic agents, we tested curcumin, a naturally occurring compound with known anti-inflammatory and antioxidative properties, in a rat model of light-induced retinal degeneration (LIRD) and in retina-derived cell lines. We hypothesized that any compound effective against LIRD, which involves significant oxidative stress and inflammation, would be a candidate for further characterization for its potential application in AMD. We observed significant retinal neuroprotection in rats fed diets supplemented with curcumin (0.2% in diet) for 2 weeks. The mechanism of retinal protection from LIRD by curcumin involves inhibition of NF-kappaB activation and down-regulation of cellular inflammatory genes. When tested on retina-derived cell lines (661W and ARPE-19), pretreatment of curcumin protected these cells from H(2)O(2)-induced cell death by up-regulating cellular protective enzymes, such as HO-1, thioredoxin. Since, curcumin with its pleiotropic activities can modulate the expression and activation of many cellular regulatory proteins such as NF-kappaB, AKT, NRF2, and growth factors, which in turn inhibit cellular inflammatory responses and protect cells; we speculate that curcumin would be an effective nutraceutical compound for preventive and augmentative therapy of AMD.

Management of an abdominal aortic aneurysm infected with Campylobacter fetus: a case report.

We present a rare case of an abdominal aortic aneurysm (AAA) infected with Campylobacter fetus. The patient presented with abdominal pain and leukocytosis, without a palpable AAA. Computed tomography (CT) of the abdomen showed a 3.1 x 3.0 cm infrarenal abdominal aneurysm with an extra-aortic fluid collection. At surgery, an in situ graft was placed. Intraoperative aortic wall cultures grew pansensitive C. fetus, and blood cultures remained negative. At 9-month follow-up, the patient was doing well without complaints. To our knowledge, this represents only the ninth reported case of an AAA with an aortic wall culture positive for C. fetus.

The effect of the 80-hour work week on general surgery resident operative case volume.

To meet the new duty hour restrictions on July 1, 2003, our general surgery residency program underwent many changes. The purpose of this study was to examine whether the implementation of these changes, made in part to comply with new duty hour restrictions, would adversely impact general surgery residents' operative volume. The operative cases of categorical surgical residents were recorded from July 1, 2000 to December 31, 2004. The main outcome measure was the median number of operative cases performed by each resident per quarter (a 3-month period). The number of in-house calls each resident took per quarter was also recorded. From 2000 to 2004, the median number of in-house calls per quarter significantly decreased (27, 25, 15, 10, and 14, respectively; P < 0.001). The median number of operative procedures performed did not vary from quarter to quarter (P = 0.49). There was a trend toward an increase in number of cases performed at the postgraduate year (PGY) 1 (P = 0.07) and 2 (P = 0.04) levels, a decrease at the PGY3 level (P = 0.058), and no change at the PGY4 and 5 years. The 80-hour work week did not adversely affect the operative experience of our categorical surgical residents despite significant reductions of in-house call.

Factors affecting long-term mortality after endovascular repair of abdominal aortic aneurysms.

HYPOTHESIS: Endovascular repair of abdominal aortic aneurysms has made considerable advancements with respect to perioperative mortality. However, fewer data are available regarding factors affecting long-term mortality, including the impact of adverse perioperative cardiac events. Perioperative clinical cardiac risk factors are significant predictors of long-term mortality. DESIGN, SETTING, AND PATIENTS: Retrospective review of a prospective database of 468 patients who underwent endovascular abdominal aortic aneurysm repair from June 3, 1996, to January 31, 2005. MAIN OUTCOME MEASURES: Preoperative, intraoperative, and postoperative factors were analyzed using multivariate Cox proportional hazards models to identify statistically significant independent predictors of long-term survival (beyond 30 days and after discharge from the hospital). RESULTS: The mean age was 74 years, and 90% of the patients were male. Median follow-up was 2.57 years (interquartile range, 0.92-4.06 years). The leading cause of death was cardiac in nature. On multivariate analysis, the number of preoperative clinical cardiac risk factors (P < .001), spending 2 or more days in the intensive care unit (P < .001), and having an ST-segment elevation myocardial infarction (P < .001) were predictors of decreased long-term survival. Of note, having a perioperative non-ST-segment elevation myocardial infarction was not predictive of decreased survival (P = .09). CONCLUSIONS: Adverse cardiac events are the leading cause of long-term mortality following endovascular repair of abdominal aortic aneurysms. Preoperative clinical cardiac risk factors are significant predictors of long-term mortality, as are a prolonged intensive care unit stay and a perioperative ST-segment elevation myocardial infarction. A perioperative non-ST-segment elevation myocardial infarction did not influence long-term outcome.

SYBR Green real-time telomeric repeat amplification protocol for the rapid quantification of telomerase activity.

The sensitive telomeric repeat amplification protocol (TRAP) permits telomerase detection in mammalian cell and tissue extracts with very low telomerase activity levels. Unfortunately, conventional TRAP assays require complex post-amplification procedures, such as polyacrylamide gel electrophoresis and densitometry, to measure telomerase products. Therefore, a real-time quantitative TRAP assay (RQ-TRAP) was optimized in the present study and evaluated in comparison with a commercially available quantitative TRAP kit and by monitoring telomerase activity in human hepatocyte cultures, human hepatoma cell lines and telomerase reconstitution experiments. The novel real-time telomerase detection method has many advantages. Other than sample extraction and real-time cycling, no additional time-consuming steps have to be performed for telomerase quantification; reliable and linear telomerase quantification is possible down to single-cell dilutions without the interference of primer-dimer artifacts, and the costs are less. Moreover, the precision is similar to other amplification-based telomerase quantification assays and the results are comparable to data obtained with two commercially available assays. The closed-tube system reduces the risk of carryover contamination and supports high throughput. In conclusion, RQ-TRAP provides a new tool for the rapid and reliable quantification of telomerase activity.

Recent trends in early outcome of adult patients after heart transplantation: a single-institution review of 251 transplants using standard donor organs.

Older age, prior transplantation, pulmonary hypertension, and mechanical support are commonly seen in current potential cardiac transplant recipients. Transplants in 436 consecutive adult patients from 1994 to 1999 were reviewed. There were 251 using standard donors in 243 patients (age range 18-69 years). To emphasize recipient risk, 185 patients who received a nonstandard donor were excluded from analysis. The indications for transplant were ischemic heart disease (n = 123, 47%), dilated cardiomyopathy (n = 82, 32%), and others (n=56, 21%). One hundred and forty-nine (57%) recipients were listed as status I; 5 and 6% were supported with an intra-aortic balloon and an assist device, respectively. The 30-d survival and survival to discharge were 94.7 and 92.7%, respectively; 1-year survival was 89.1%. Causes of early death were graft failure (n = 6), infection (n = 4), stroke (n = 4), multiorgan failure (n = 3) and rejection (n = 2). Predictors were balloon pump use alone (OR= 11.4, p =0.002), pulmonary vascular resistance > 4 Wood units (OR = 5.7, p = 0.007), pretransplant creatinine > 2.0 mg/dL (OR = 6.9, p = 0.004) and female donor (OR = 8.3, p = 0.002). Recipient age and previous surgery did not affect short-term survival. Heart transplantation in the current era consistently offers excellent early and 1-year survival for well-selected recipients receiving standard donors. Early mortality tends to reflect graft failure while hospital mortality may be more indicative of recipient selection.
