Tocilizumab in Hospitalized Patients with Severe Covid-19 Pneumonia.

BACKGROUND: Coronavirus disease 2019 (Covid-19) is associated with immune dysregulation and hyperinflammation, including elevated interleukin-6 levels. The use of tocilizumab, a monoclonal antibody against the interleukin-6 receptor, has resulted in better outcomes in patients with severe Covid-19 pneumonia in case reports and retrospective observational cohort studies. Data are needed from randomized, placebo-controlled trials. METHODS: In this phase 3 trial, we randomly assigned patients who were hospitalized with severe Covid-19 pneumonia in a 2:1 ratio receive a single intravenous infusion of tocilizumab (at a dose of 8 mg per kilogram of body weight) or placebo. Approximately one quarter of the participants received a second dose of tocilizumab or placebo 8 to 24 hours after the first dose. The primary outcome was clinical status at day 28 on an ordinal scale ranging from 1 (discharged or ready for discharge) to 7 (death) in the modified intention-to-treat population, which included all the patients who had received at least one dose of tocilizumab or placebo. RESULTS: Of the 452 patients who underwent randomization, 438 (294 in the tocilizumab group and 144 in the placebo group) were included in the primary and secondary analyses. The median value for clinical status on the ordinal scale at day 28 was 1.0 (95% confidence interval [CI], 1.0 to 1.0) in the tocilizumab group and 2.0 (non-ICU hospitalization without supplemental oxygen) (95% CI, 1.0 to 4.0) in the placebo group (between-group difference, -1.0; 95% CI, -2.5 to 0; P = 0.31 by the van Elteren test). In the safety population, serious adverse events occurred in 103 of 295 patients (34.9%) in the tocilizumab group and in 55 of 143 patients (38.5%) in the placebo group. Mortality at day 28 was 19.7% in the tocilizumab group and 19.4% in the placebo group (weighted difference, 0.3 percentage points; 95% CI, -7.6 to 8.2; nominal P = 0.94). CONCLUSIONS: In this randomized trial involving hospitalized patients with severe Covid-19 pneumonia, the use of tocilizumab did not result in significantly better clinical status or lower mortality than placebo at 28 days.

Process, resource and success factors associated with chimeric antigen receptor T-cell therapy for multiple myeloma.

Background: Chimeric antigen receptor T-cell (CAR-T) therapy represents a new frontier in multiple myeloma. It is important to understand critical success factors (CSFs) that may optimize its use in this therapeutic area. Methods: We estimated the CAR-T process using time-driven activity-based costing. Information was obtained through interviews at four US oncology centers and with payer representatives, and through publicly available data. Results: The CAR-T process comprises 13 steps which take 177 days; it was estimated to include 46 professionals and ten care settings. CSFs included proactive collaboration, streamlined reimbursement and CAR-T administration in alternative settings when possible. Implementing CSFs may reduce episode time and costs by 14.4 and 13.2%, respectively. Conclusion: Our research provides a blueprint for improving efficiencies in CAR-T therapy, thereby increasing its sustainability for multiple myeloma.

Patients with multiple myeloma can now be treated with chimeric antigen receptor T-cell (CAR-T) therapy. We studied how CAR-T therapy is used for multiple myeloma. We also studied things that could help make this therapy easier for doctors to use. The CAR-T process takes 13 steps and 177 days. It begins with the choice to use the therapy and ends about 100 days after it is used. The process uses 46 different healthcare professionals and ten different locations. We found several possible changes that can improve this process. Of these changes, three stand out. First, improved teamwork between members of the care team can help them prepare for and resolve possible problems. Second, reducing insurance red tape will make it easier to provide CAR-T therapy to patients. Third, allowing use of CAR-T therapy in places other than hospitals can help more patients receive this therapy. If applied, these three things may lower the time needed to treat patients by 14.4% and may reduce costs by 13.2%.

Anticoagulation for the treatment of venous thromboembolism in patients with brain metastases: a meta-analysis and systematic review.

The risk benefit decision in providing anticoagulation for patients with brain metastases is amongst the most difficult decisions faced by clinicians. The purpose of our study was to evaluate both the risk of intracerebral hemorrhage (ICH) associated with anticoagulation therapy and the effect of anticoagulation on survival in patients with brain metastases and venous thromboembolism (VTE). A systematic review of the literature was performed via the PubMed, EMBASE, and the Cochrane databases. Our initial search resulted in 1304 unique citations, and 5 studies satisfied all eligibility criteria and were included for analysis. The odds ratio for development of ICH in the setting of anticoagulation was 1.37 (CI 0.86-2.17, p = 0.18). The hazard ratio for survival was 0.96 (CI 0.51-1.81, p = 0.90). While limited, the best available evidence suggests that there is no increased risk of ICH and no survival benefit associated with providing anticoagulation to patients with brain metastases who develop VTE. These patients merit individualized discussion of the risk and benefit of anticoagulation therapy. Current guidelines should be updated to include more recent studies and highlight the uncertainty of the net clinical benefit associated with anticoagulation.

Reduced Cytokine Release Syndrome and Improved Outcomes with Earlier Immunosuppressive Therapy in Haploidentical Stem Cell Transplantation.

The optimal timing of immunosuppression and post-transplantation cyclophosphamide (PTCy) in haploidentical hematopoietic stem cell transplantation (haplo-HSCT) is unknown. However, cytokine release syndrome (CRS) following haplo-HSCT is associated with worse transplantation outcomes, and the incidence of CRS may be affected by the timing of immunosuppression and PTCy. In this study, we compared CRS and other transplantation outcomes in 2 cohorts receiving different immunosuppression and PTCy schedules following haplo-HSCT. This was a retrospective cohort study of 91 patients who underwent haplo-HSCT at the Intermountain Health Blood and Marrow Transplant Program. The original or standard haplo-HSCT GVHD prophylaxis regimen included PTCy on days +3 and +4, with mycophenolate mofetil (MMF) and tacrolimus starting on day +5. The modified regimen adopted in November 2020 changed PTCy to days +3 and +5, with earlier introduction of tacrolimus and MMF, on day -1 and day 0, respectively. Grade ≥1 CRS occurred in 32% of patients in the modified regimen, in 82% of patients in the standard regimen (P <.0001), and 65% overall. Likewise, grade ≥2 CRS was lower with the modified regimen (16% versus 57%; P = .0002). The mean duration of CRS symptoms was longer with the standard regimen (3.14 days versus 1.44 days; P = .0003). The incidence of acute graft-versus-host disease grade III-IV or extensive chronic GVHD (cGVHD) at 1 year was lower in the modified regimen (6% versus 32%; P = .0068). No differences between the standard and modified regimens were seen in overall survival, relapse, or GVHD-free relapse-free survival (GRFS), although there appeared to be a trend toward improved GRFS with the modified regimen. Post hoc analysis comparing GRFS in patients with CRS and those without CRS found that CRS was associated with lower GRFS at 1 year (36% versus 63%; P = .0138). The duration of broad-spectrum antibiotic therapy was decreased by 7.5 days (P = .0017) and the time to hospital discharge was reduced by 7.1 days (P = .0241) with the modified regimen. This is the first analysis to evaluate and find a difference in CRS with early initiation of immunosuppressive therapy in haplo-HSCT. Our results suggest that this modified GVHD regimen benefits patients by reducing CRS and high-grade GVHD compared to the standard PTCy-based GVHD prophylaxis regimen in haplo-HSCT. Additionally, this novel regimen did not appear to negatively impact outcomes.

Multiplexed Gastrointestinal PCR Panels for the Evaluation of Diarrhea in Hematopoietic Stem Cell Transplantation Recipients.

Multiplexed gastrointestinal PCR panels (MGPPs) are frequently used to aid the diagnosis and management of diarrhea in hematopoietic stem cell transplantation (HCT) recipients. Many issues related to the optimal use of MGPPs in HCT patients remain to be clarified. We aimed to better define MGPP diagnostic and therapeutic stewardship in HCT recipients, including indications for and benefits of testing, optimal timing of tests, and interpretation of results. We retrieved 463 consecutive MGPPs ordered on 651 consecutive first HCT (312 allogeneic, 339 autologous) performed at our institution between June 2015 and June 2023. One hundred and sixteen of the 463 MGPPs (25%) identified at least 1 diarrheagenic pathogen, and 12 (3%) identified more than 1 diarrheagenic pathogen. A positive result was more likely if the test was ordered within 48 hours of a hospital admission (41%; 32 of 78) or as an outpatient (41%; 46 of 111) compared with evaluation of hospital-onset diarrhea (14%; 38 of 274). Among the positive results, the most frequent pathogens identified included Clostridioides difficile (64%), diarrheagenic Escherichia coli (20%), norovirus (9%), and adenovirus 40/41 (5%). Thirty-eight percent of the positive C. difficile MGPP determinations were associated with a positive test for toxin. In our allogeneic HCT cohort, 3% of MGPPs for hospital-onset diarrhea yielded an organism other than C. difficile. Fifty-six percent of positive and 14% of all submitted tests resulted in a change in treatment. For organisms other than C. difficile, only 1% of all tests and 5% of positive tests resulted in initiation of therapy. For patients at risk for acute graft-versus-host disease (aGVHD), a positive or negative MGPP result was not predictive of a new diagnosis of aGVHD in proximity to diarrhea onset. These results suggest that MGPP testing is most useful when performed at hospital admission or on an outpatient basis. Because MGPPs are sensitive and do not distinguish between colonization and causes of diarrhea, caution is needed when interpreting results, especially for toxin-negative C. difficile and diarrheagenic gram-negative organisms.

Antineoplastic Therapy Administration Safety Standards for Adult and Pediatric Oncology: ASCO-ONS Standards.

PURPOSE: To update the ASCO-Oncology Nursing Society (ONS) standards for antineoplastic therapy administration safety in adult and pediatric oncology and highlight current standards for antineoplastic therapy for adult and pediatric populations with various routes of administration and location. METHODS: ASCO and ONS convened a multidisciplinary Expert Panel with representation of multiple organizations to conduct literature reviews and add to the standards as needed. The evidence base was combined with the opinion of the ASCO-ONS Expert Panel to develop antineoplastic safety standards and guidance. Public comments were solicited and considered in preparation of the final manuscript. RESULTS: The standards presented here include clarification and expansion of existing standards to include home administration and other changes in processes of ordering, preparing, and administering antineoplastic therapy; the advent of immune effector cellular therapy; the importance of social determinants of health; fertility preservation; and pregnancy avoidance. In addition, the standards have added a fourth verification. STANDARDS: Standards are provided for which health care organizations and those involved in all aspects of patient care can safely deliver antineoplastic therapy, increase the quality of care, and reduce medical errors.Additional information is available at www.asco.org/standards and www.ons.org/onf.

Religious orientation and health among active older adults in the United States.

This study utilizes a combination of intrinsic and extrinsic Religious Orientation Scales to explore the connection between religion and health in a sample of physically active, older adults. The revised Religious Orientation Scale and the RAND Short Form 36 (SF-36) were adopted to relate religious orientation (intrinsic, extrinsic, pro-religious, and non-religious) and self-rated mental and physical health status. Individuals of pro-religious orientation reported significantly worse health for physical functioning, role limitations due to physical health, and energy or fatigue when compared with those of all other religious orientations; however, no dose-response relationships were found between religious orientation and self-rated health. The results of this study indicate that deleterious health effects may accompany pro-religious orientation. Caution is provided for directors of religious programs for older adults.

Overcoming Barriers to Referral for Chimeric Antigen Receptor T Cell Therapy in Patients with Relapsed/Refractory Diffuse Large B Cell Lymphoma.

Diffuse large B cell lymphoma (DLBCL) is the most prevalent subtype of non-Hodgkin lymphoma. Although outcomes to frontline therapy are encouraging, patients who are refractory to or in relapse after first-line therapy experience inferior outcomes. A significant proportion of patients treated with additional lines of cytotoxic chemotherapy ultimately succumb to their disease, as established in the SCHOLAR-1 study. Chimeric antigen receptor (CAR) T cell therapy is a novel approach to cancer management that reprograms a patient's own T cells to better target and eliminate cancer cells. It was initially approved by the US Food and Drug Administration for patients with relapsed/refractory (r/r) DLBCL as a third line of treatment. Based on recently published randomized data, CAR-T therapy (axicabtagene ciloleucel and lisocabtagene maraleucel) also has been approved as a second line of treatment for patients who are primary refractory or relapse within 12 months of first-line therapy. Despite the proven efficacy in treating r/r DLBCL with CD19-directed CAR-T therapy, several barriers may prevent eligible patients from receiving treatment. Barriers to CAR-T therapy include cost of therapy, patient hesitancy, required travel to academic treatment centers, nonreferrals, poor understanding of CAR-T therapy, lack of caregiver support, knowledge of available resources, and timely patient selection by referring oncologists. In this review, we provide an overview of the FDA-approved CD19-directed CAR-T cell therapies (tisagenlecleucel, axicabtagene ciloleucel, and lisocabtagene maraleucel) from pivotal clinical trials and supporting real-world evidence from retrospective studies. In both clinical trials and real-world settings, CAR-T therapy has been shown to be safe and efficacious for treating patients with r/r DLBCL: however, several barriers prevent eligible patients from accessing these therapies. Barriers to referrals for CAR-T therapy are described, along with recommendations to improve collaboration between community oncologists and physicians from CAR-T therapy treatment centers and subsequent long-term care of patients in community treatment centers.

Transfer of Extended Spectrum Cephalosporin Resistant Enterobacteriaceae Among Patients on an HSCT Unit and the Value of Surveillance and Contact Isolation.

The mechanism(s) of acquisition of extended-spectrum cephalosporin-resistant Enterobacteriaceae (ESCRE) on inpatient hospital units dedicated to hematopoietic stem cell transplantation (HSCT) is unclear. The objectives of this study were to determine whether ESCRE organisms are transmitted among patients housed on a HSCT unit, clarify the mechanisms involved, and determine whether routine surveillance for ESCRE carriage and contact isolation for ESCRE carriers is beneficial. The study was conducted on a 30-bed inpatient unit dedicated to the care of patients with hematologic malignancies and HSCT recipients. To investigate whether ESCRE organisms may be transmitted vertically to subsequent room occupants, presumably through contamination of room surfaces, we (1) cultured 6 high touch areas in 10 rooms before and 9 rooms after terminal cleaning that had been occupied by patients with ESCRE carriage, (2) determined the in vitro survivals of our most common clinical ESCRE species, and (3) followed the subsequent room occupants of 54 consecutive ESCRE colonized patients for the development of inpatient acquired ESCRE carriage. To investigate whether ESCRE organisms are transmitted horizontally among inpatients we (1) sequenced 60 available ESCRE Escherichia coli isolates obtained from unit inpatients and searched for identities using complete-genome multisequence locus typing (cgMLST) and (2) retrospectively tabulated the cumulative rates of acquired ESCRE carriage in 356 patients admitted for a first HSCT before (200 patients) or after (156 patients) institution of universal ESCRE stool surveillance and contact isolation for carriers. No ESCRE organisms were cultured from patient rooms before or after terminal cleaning. In vitro, few, if any, ESCRE organisms survived longer than 2 hours. Nine of the subsequent occupants of a room in which a patient with ESCRE carriage had resided were detected with ESCRE carriage, only 2 of whom carried the same species as that of the prior occupant. DNA sequencing and cgMLST determination of the 60 E. coli isolates showed 53 cgMLST strains. Seven of the 53 strains were shared by 2 patients. After institution of universal ESCRE surveillance/isolation there was a significant decline in acquired ESCRE carriage among HSCT recipients. We conclude that vertical transmission of ESCRE organisms through room contamination appears to be uncommon on modern HSCT units. Conversely, our results are consistent with the horizontal spread of ESCRE organisms, probably mediated by intermediate vectors such as personnel or shared equipment. Further studies are needed to better define the magnitude of and risk factors for ESCRE horizontal transfers and the benefits of ESCRE surveillance/isolation.

A comparison of religious orientation and health between Whites and Hispanics.

The study of religious orientation thus far has neglected the influence of race/ethnicity as well as all four religious orientations (intrinsic, extrinsic, pro-religious and nonreligious) in explaining differences in both physical and psychological health. A representative sample of 250 Hispanics and 236 non-Hispanic Whites in Utah was drawn and analysed for differences in health (self-rated health, life satisfaction, exercise) according to race/ethnicity, religious orientation and religious attendance. Responses to the Religious Orientation Scale differed significantly by race/ethnicity, indicating that future studies of religious orientation should take cultural context into account. For both Whites and Hispanics, pro-religious individuals reported the highest life satisfaction scores, which highlight the utility of employing the fourfold religious orientation typology.

Successful administration of chimeric antigen receptor (CAR) T-cell therapy in patients requiring hemodialysis.

Chimeric antigen receptor (CAR) T-cell therapy has revolutionized the treatment of relapsed/refractory B-cell malignancies. However, there is no data on the safety and efficacy of CAR T-cell therapy in patients with end stage renal disease (ESRD) requiring dialysis. In this report, we present two patients with DLBCL and ESRD who were successfully treated with different CAR T-cell products. Patient #1 is a 66 year-old woman with a history of HIV who was treated to complete response with axicabtagene ciloleucel with treatment complicated by grade 1 cytokine release syndrome (CRS) and grade 2 immune effector cell-associated neurolotoxicity syndrome (ICANS). Patient #2 is 52 year old woman whose ESRD was caused by ifosphamide toxicity and was treated to complete response with lisocabtagene maraleucel and did not experience either CRS or ICANS. Both patients received lymphodepletion chemotherapy with fludarabine and cyclophosphamide, which was dose-adjusted for ESRD with scheduled dialysis 12 h after each dose of lymphodepletion chemotherapy. Patients with DLBCL and ESRD can be safely administered both lymphodepletion chemotherapy and CAR T-cell therapy. Additionally, the fact that both patients achieved complete response to therapy suggests that CAR T-cell therapy should be strongly considered in patients with ESRD. Long-term follow up is needed to determine if therapy in this setting is of curative intent.

Tocilizumab in patients hospitalised with COVID-19 pneumonia: Efficacy, safety, viral clearance, and antibody response from a randomised controlled trial (COVACTA).

Background: In COVACTA, a randomised, placebo-controlled trial in patients hospitalised with coronavirus disease-19 (COVID-19), tocilizumab did not improve 28-day mortality, but shortened hospital and intensive care unit stay. Longer-term effects of tocilizumab in patients with COVID-19 are unknown. Therefore, the efficacy and safety of tocilizumab in COVID-19 beyond day 28 and its impact on Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) clearance and antibody response in COVACTA were investigated. Methods: Adults in Europe and North America hospitalised with COVID-19 (N = 452) between April 3, 2020 and May 28, 2020 were randomly assigned (2:1) to double-blind intravenous tocilizumab or placebo and assessed for efficacy and safety through day 60. Assessments included mortality, time to hospital discharge, SARS-CoV-2 viral load in nasopharyngeal swab and serum samples, and neutralising anti-SARS-CoV-2 antibodies in serum. ClinicalTrials.gov registration: NCT04320615. Findings: By day 60, 24·5% (72/294) of patients in the tocilizumab arm and 25·0% (36/144) in the placebo arm died (weighted difference -0·5% [95% CI -9·1 to 8·0]), and 67·0% (197/294) in the tocilizumab arm and 63·9% (92/144) in the placebo arm were discharged from the hospital. Serious infections occurred in 24·1% (71/295) of patients in the tocilizumab arm and 29·4% (42/143) in the placebo arm. Median time to negative reverse transcriptase-quantitative polymerase chain reaction result in nasopharyngeal/oropharyngeal samples was 15·0 days (95% CI 14·0 to 21·0) in the tocilizumab arm and 21·0 days (95% CI 14·0 to 28·0) in the placebo arm. All tested patients had positive test results for neutralising anti-SARS-CoV-2 antibodies at day 60. Interpretation: There was no mortality benefit with tocilizumab through day 60. Tocilizumab did not impair viral clearance or host immune response, and no new safety signals were observed. Future investigations may explore potential biomarkers to optimize patient selection for tocilizumab treatment and combination therapy with other treatments. Funding: F.

Novice vs expert inter-rater reliability of the balance error scoring system in children between the ages of 5 and 14.

BACKGROUND: The Balance Error Scoring System (BESS) is a tool to measure balance, however, no studies have shown its reliability between novice and expert raters. RESEARCH QUESTION: What is the inter-rater reliability of BESS measurements when performed by novice raters compared to experts, and does completion of a focused, online training module increase the inter-rater reliability among novice raters? METHODS: In this reliability study, 5 novice volunteers were asked to independently rate BESS tests from 50 random prerecorded BESS videos of normal healthy subjects aged 5-14. Novice raters regraded the same 50 videos after receiving a formal training. The novices' scores before and after the formal training were compared to one another and then the scores were compared to 4 expert scores. Intraclass correlation (ICC) with 95 % confidence intervals or percent agreements were calculated and compared across groups. RESULTS: For the total BESS score, novice raters showed good reliability (ICC 0.845) which did not change with a formal training (ICC 0.846). Expert raters showed excellent reliability (ICC 0.929). Poor to moderate reliability was noted in the foam stance-single leg in the untrained novice and trained novice group (ICCs 0.452 and 0.64 L respectively). SIGNIFICANCE: BESS testing by novice raters with only written instruction and no formal training yields good inter-rater reliability. In contrast, BESS testing by expert raters yields excellent reliability. A focused training for novice raters conferred a small improvement in the reliability of the scoring of the single leg stance on foam condition but not a significant difference to the overall BESS score. While novices demonstrated promising reliability for overall BESS scores, optimizing clinical research using the BESS with expert raters show the highest reliability.

Ofatumumab, Etoposide, and Cytarabine Intensive Mobilization Regimen in Patients with High-risk Relapsed/Refractory Diffuse Large B-Cell Lymphoma Undergoing Autologous Stem Cell Transplantation.

BACKGROUND: More than one-half of high-risk patients with relapsed/refractory (rr) diffuse large B-cell lymphoma (DLBCL) relapse after autologous hematopoietic cell transplantation (auto-HCT). In this phase II study, we investigate the long-term outcomes of high-risk patients with rrDLBCL receiving intensive consolidation therapy (ICT) with OVA (ofatumumab, etoposide, and high-dose cytarabine) prior to auto-HCT. PATIENTS AND METHODS: The primary endpoints were the ability of OVA to mobilize peripheral stem cells and the 2-year progression-free survival (PFS) rate following OVA. Secondary endpoints included safety, 2-year overall survival (OS), impact of cell of origin (COO), and the prognostic utility of next-generation sequencing minimal residual disease (MRD) testing. We simultaneously retrospectively assessed the outcomes of DLBCL patients who underwent ICT with a similar regimen at our institution. RESULTS: Twenty-seven patients received salvage chemotherapy, with a response rate of 25% in patients with germinal center B-cell (GCB)-DLBCL versus 92% in patients with non-GCB-DLBCL (P = .003). Nineteen responding patients underwent ICT with OVA (100% successful stem cell mobilization). The 2-year PFS and OS rate was 47% and 59%, respectively, with no difference based on COO. Similar findings were observed when the study and retrospective cohorts were combined. Neutropenia was the most common toxicity (47%). MRD-negative patients at the completion of salvage had a median OS of not reached versus 3.5 months in MRD-positive patients (P = .02). CONCLUSIONS: OVA followed by auto-HCT is effective and safe for high-risk rrDLBCL. Patients with GCB-DLBCL had a lower response to salvage chemotherapy, but no difference in outcomes based on COO was seen after auto-HCT. MRD testing in the relapsed setting was predictive of long-term survival.

Tocilizumab and remdesivir in hospitalized patients with severe COVID-19 pneumonia: a randomized clinical trial.

PURPOSE: Trials of tocilizumab in patients with severe COVID-19 pneumonia have demonstrated mixed results, and the role of tocilizumab in combination with other treatments is uncertain. Here we evaluated whether tocilizumab plus remdesivir provides greater benefit than remdesivir alone in patients with severe COVID-19 pneumonia. METHODS: This randomized, double-blind, placebo-controlled, multicenter trial included patients hospitalized with severe COVID-19 pneumonia requiring > 6 L/min supplemental oxygen. Patients were randomly assigned (2:1 ratio) to receive tocilizumab 8 mg/kg or placebo intravenously plus ≤ 10 days of remdesivir. The primary outcome was time from randomization to hospital discharge or "ready for discharge" (defined as category 1, assessed by the investigator on a 7-category ordinal scale of clinical status) to day 28. Patients were followed for 60 days. RESULTS: Among 649 enrolled patients, 434 were randomly assigned to tocilizumab plus remdesivir and 215 to placebo plus remdesivir. 566 patients (88.2%) received corticosteroids during the trial to day 28. Median time from randomization to hospital discharge or "ready for discharge" was 14 (95% CI 12-15) days with tocilizumab plus remdesivir and 14 (95% CI 11-16) days with placebo plus remdesivir [log-rank P = 0.74; Cox proportional hazards ratio 0.97 (95% CI 0.78-1.19)]. Serious adverse events occurred in 128 (29.8%) tocilizumab plus remdesivir and 72 (33.8%) placebo plus remdesivir patients; 78 (18.2%) and 42 (19.7%) patients, respectively, died by day 28. CONCLUSIONS: Tocilizumab plus remdesivir did not shorten time to hospital discharge or "ready for discharge" to day 28 compared with placebo plus remdesivir in patients with severe COVID-19 pneumonia.

Conditional survival among cancer patients in the United States.

PURPOSE: To report 5-year relative cancer survival probabilities conditional on having already survived > or = 1 years after the initial diagnosis for 11 cancer sites, diagnosed during 1990-2001 and followed through 2006. METHODS: Analyses are based on 1,151,496 cancer cases in population-based cancer registries in the Surveillance, Epidemiology, and End Results Program of the National Cancer Institute. RESULTS: The 5-year relative conditional survival probability tended to improve with each year already survived. Improvement was greatest for more lethal cancers (e.g., lung or pancreas) and for cases with a more advanced stage at diagnosis. The 5-year relative survival probability conditional on already having survived 5 years exceeded 90% for locally staged prostate cancer, melanoma (whites only), breast cancer (females only), corpus uteri cancer, urinary bladder cancer, Hodgkin's lymphoma, rectal cancer, colon cancer, ovary cancer, and pancreatic cancer. Only lung cancer did not reach 90%. For these cancer sites combined, 5-year relative survival probability conditional on already having survived 5 years averaged about 85% for regionally staged disease, 68% for distant staged disease, and 87% for unknown staged disease. The 5-year relative conditional survival probability tended to be significantly lower among patients diagnosed at older ages, among males, among nonwhites, and among those diagnosed during 1990-1995 compared with later years. CONCLUSION: Conditional survival probability estimation provides further useful prognostic information to cancer patients, tailored to the time already survived since diagnosis.

The diminishing role of transurethral resection of the prostate.

BACKGROUND: This study provides an update of patterns in transurethral resection of the prostate (TURP) rates in the United States and the extent of TURP-detected prostate cancer incidence rates. METHODS: Analyses are based on data from the National Hospital Discharge Survey, the Surveillance, Epidemiology, and End Results Program, and the U.S. Census Bureau for the years 1996 through 2006. RESULTS: TURP procedure rates were 6, 14, and 18 times greater in men aged 60 to 69, 70 to 79, and >or=80 years compared with men aged 50 to 59, respectively. During 1996-2006, the estimated annual percentage change in TURP rates was -10.5 (95% confidence interval [95% CI] -14.1 to -6.7) for ages 50 to 59, -7.4 (95% CI -9.2 to -5.6) for ages 60 to 69, -6.2 (95% CI -7.6 to -4.8) for ages 70 to 79, and -7.7 (95% CI -9.5 to -5.8) for ages >or=80 years. TURP-detected prostate cancer incidence rates were 2, 7, and 17 times greater in men aged 60 to 69, 70 to 79, and >or=80 years compared with men aged 50 to 59, respectively. The estimated annual percentage change in trend was -17.8 (-20.6, -15.0) for ages 50 to 59, -14.8 (-16.6, -13.0) for ages 60 to 69, -10.8 (-12.0, -9.7) for ages 70 to 79, and -8.2 (-10.0, -6.5) for ages >or=80 years. Trends in prostate cancer incidence rates peaked in 2002 and decreased thereafter. Some of the decreasing trend in rates among older age groups is because of a decrease in TURPs and consequently a decrease in incidental TURP-detected cases. CONCLUSIONS: TURP procedure rates and incidental TURP-detected prostate cancer incidence rates have declined and will likely continue to decline in the future.

Current Approaches to Transplantation for FLT3-ITD AML.

PURPOSE OF REVIEW: This review discusses the current standard of care for incorporation of FLT3 TKIs and HCT into the treatment of FLT3-ITD AML. Additionally, this review provides an approach to the patient with relapsed/refractory disease. RECENT FINDINGS: Over the last decade, the routine use of HCT as consolidative therapy and the development of FLT3 TKIs have significantly improved remission rates and overall survival. The value and challenges of MRD assessment in FLT3 disease are discussed and current mechanisms of relapse are explored, as are the ongoing questions in the field that current clinical trials are seeking to answer. FLT3-ITD mutations are common in acute myeloid leukemia and historically have been associated with a poor prognosis, but with the incorporation of FLT3 TKIs and routine use of allogeneic stem cell transplant as consolidative therapy, outcomes have improved dramatically. Ongoing research seeks to answer how and when to best use current therapies, and how to overcome resistance to FLT3 inhibition.

Clinical criteria for COVID-19-associated hyperinflammatory syndrome: a cohort study.

BACKGROUND: A subset of patients with COVID-19 develops a hyperinflammatory syndrome that has similarities with other hyperinflammatory disorders. However, clinical criteria specifically to define COVID-19-associated hyperinflammatory syndrome (cHIS) have not been established. We aimed to develop and validate diagnostic criteria for cHIS in a cohort of inpatients with COVID-19. METHODS: We searched for clinical research articles published between Jan 1, 1990, and Aug 20, 2020, on features and diagnostic criteria for secondary haemophagocytic lymphohistiocytosis, macrophage activation syndrome, macrophage activation-like syndrome of sepsis, cytokine release syndrome, and COVID-19. We compared published clinical data for COVID-19 with clinical features of other hyperinflammatory or cytokine storm syndromes. Based on a framework of conserved clinical characteristics, we developed a six-criterion additive scale for cHIS: fever, macrophage activation (hyperferritinaemia), haematological dysfunction (neutrophil to lymphocyte ratio), hepatic injury (lactate dehydrogenase or asparate aminotransferase), coagulopathy (D-dimer), and cytokinaemia (C-reactive protein, interleukin-6, or triglycerides). We then validated the association of the cHIS scale with in-hospital mortality and need for mechanical ventilation in consecutive patients in the Intermountain Prospective Observational COVID-19 (IPOC) registry who were admitted to hospital with PCR-confirmed COVID-19. We used a multistate model to estimate the temporal implications of cHIS. FINDINGS: We included 299 patients admitted to hospital with COVID-19 between March 13 and May 5, 2020, in analyses. Unadjusted discrimination of the maximum daily cHIS score was 0·81 (95% CI 0·74-0·88) for in-hospital mortality and 0·92 (0·88-0·96) for mechanical ventilation; these results remained significant in multivariable analysis (odds ratio 1·6 [95% CI 1·2-2·1], p=0·0020, for mortality and 4·3 [3·0-6·0], p<0·0001, for mechanical ventilation). 161 (54%) of 299 patients met two or more cHIS criteria during their hospital admission; these patients had higher risk of mortality than patients with a score of less than 2 (24 [15%] of 138 vs one [1%] of 161) and for mechanical ventilation (73 [45%] vs three [2%]). In the multistate model, using daily cHIS score as a time-dependent variable, the cHIS hazard ratio for worsening from low to moderate oxygen requirement was 1·4 (95% CI 1·2-1·6), from moderate oxygen to high-flow oxygen 2·2 (1·1-4·4), and to mechanical ventilation 4·0 (1·9-8·2). INTERPRETATION: We proposed and validated criteria for hyperinflammation in COVID-19. This hyperinflammatory state, cHIS, is commonly associated with progression to mechanical ventilation and death. External validation is needed. The cHIS scale might be helpful in defining target populations for trials and immunomodulatory therapies. FUNDING: Intermountain Research and Medical Foundation.

Posttransplant cyclophosphamide in allogeneic bone marrow transplantation for the treatment of nonmalignant hematological diseases.

We present a single-center retrospective series of allogeneic bone marrow transplantation (BMT) with the use of posttransplant cyclophosphamide (PTCy) in the setting of nonmalignant hematological conditions. Nine patients were treated between 2013 and 2019. Nonmyeloablative conditioning consisted of antithymocyte globulin, fludarabine, low-dose cyclophosphamide, and total body irradiation (200cGy) followed by allogeneic bone marrow infusion. Post-BMT GVHD prophylaxis was with PTCy, tacrolimus, and mycophenolate mofetil. At a median follow-up of 24 months (range 4, 63), all patients are alive, with donor-derived hematopoiesis and free of significant acute or chronic GVHD. Donors were haploidentical (n = 6), fully matched unrelated (n = 2), and fully matched sibling (n = 1). Neutrophil and platelet engraftment occurred at a median of 21 days and 33 days, respectively, after transplantation. Three patients (3/9, 33%) experienced stage 1-2 acute skin GVHD. The only cases of chronic GVHD are in three patients (3/9, 33%) with ocular disease (two mild, one moderate). No patient has required systemic immunosuppression beyond 12 months after BMT. PTCy-based nonmyeloablative allogeneic BMT is safe and effective for nonmalignant hematologic conditions and should be prospectively compared with historical regimens.
