Relationship between the combination of platelet count and neutrophil-lymphocyte ratio and prognosis of patients with advanced non-small cell lung cancer treated with immune checkpoint inhibitors plus chemotherapy: A retrospective cohort study.

BACKGROUND: The relationship between the combination of platelet count and neutrophil-lymphocyte ratio (COP-NLR) and prognosis in patients with advanced non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitor (ICI) combination therapy with chemotherapy remains unclear. Thus, we investigated prognostic factors, including the COP-NLR, to identify patients who could benefit from the therapeutic efficacy of ICI combination therapy for advanced NSCLC. Furthermore, we evaluated the relationship between the COP-NLR score during ICI combination therapy and treatment response. METHODS: We conducted a retrospective cohort study of 88 patients with NSCLC who initially received ICI combination therapy. The primary outcome was overall survival (OS). The prognostic factors were extracted using the Cox proportional hazards model. The relationship between COP-NLR score at 3 weeks after starting ICI combination therapy and a good response (complete response [CR] and partial response [PR]) to treatment was analyzed using the chi-square test. RESULTS: The median OS was 15.7 months. In the multivariable analysis, Eastern Cooperative Oncology Group Performance Status (ECOG PS) 2, distant metastatic sites ≥2, and baseline COP-NLR scores of 1, 2 were extracted as significant poor prognostic factors. The proportion of patients with CR and PR in the 3-week COP-NLR score of 0 group was significantly higher than that in scores of 1, 2 group. CONCLUSIONS: Baseline COP-NLR, ECOG PS, and number of distant metastatic sites were prognostic factors in patients with NSCLC with ICI combination therapy. A lower 3-week COP-NLR was associated with a good response to treatment.

Anti-vascular endothelial growth factor biosimilars for neovascular age-related macular degeneration.

RATIONALE: Neovascular age-related macular degeneration (AMD) is a progressive eye disease characterized by choroidal neovascularization (CNV) and is a leading cause of vision loss and disability worldwide. Although intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy is an effective treatment option that helps to prevent vision loss or to improve visual acuity in people with neovascular AMD, treatment imposes a significant financial burden on patients and healthcare systems. A biosimilar is a biological product that has been developed to be nearly identical to a previously approved biological product. The use of biosimilars may help reduce costs and so may increase patient access to effective biologic medicines with similar levels of safety to the drugs on which they are based. OBJECTIVES: To assess the benefits and harms of anti-VEGF biosimilar agents compared with their corresponding anti-VEGF agents (i.e. the reference products) that have obtained regulatory approval for intravitreal injections in people with neovascular AMD. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, two other databases, and two trials registries together with reference checking and contact with study authors to identify studies that are included in the review. The latest search date was 2 June 2023. ELIGIBILITY CRITERIA: We included randomized controlled trials (RCTs) that compared approved anti-VEGF biosimilars with their reference products for treating the eyes of adult participants (≥ 50 years) who had an active primary or recurrent choroidal neovascularization lesion secondary to neovascular AMD. OUTCOMES: Our outcomes were: best-corrected visual acuity (BCVA), central subfield thickness (CST), vision-related quality of life, serious ocular and non-ocular adverse events (AE), treatment-emergent adverse events (TEAEs), anti-drug antibodies (ADAs), and serum concentrations of biosimilars and reference drugs. RISK OF BIAS: We assessed the risk of bias (RoB) for seven outcomes reported in a summary of findings table by using the Cochrane RoB 2 tool. SYNTHESIS METHODS: We synthesized results for each outcome using meta-analysis, where possible, by calculating risk ratios (RR) and mean differences (MD) with 95% confidence intervals (CI) for dichotomous outcomes and continuous outcomes, respectively. Where this was not possible due to the nature of the data, we summarized the results narratively. We used GRADE to assess the certainty of evidence for prespecified outcomes. INCLUDED STUDIES: We included nine parallel-group multi-center RCTs that enrolled a total of 3814 participants (3814 participating eyes), with sample sizes that ranged from 160 to 705 participants per study. The mean age of the participants in these studies ranged from 67 to 76 years, and the proportion of women ranged from 26.5% to 58.7%. Ranibizumab (Lucentis) was the reference product in seven studies, and aflibercept (Eyelea) was the reference product in two others. All the included studies had been supported by industry. The follow-up periods ranged from 12 to 52 weeks (median 48 weeks). Five studies (56%) were conducted in multi-country settings across Europe, North America and Asia, two studies in India, and one each in Japan and the Republic of Korea. We judged all the included studies to have met high methodological standards. SYNTHESIS OF RESULTS: With regard to efficacy, our meta-analyses demonstrated that anti-VEGF biosimilars for neovascular AMD resulted in little to no difference compared with the reference products for BCVA change at 8 to 12 weeks (MD -0.55 Early Treatment Diabetic Retinopathy Study (ETDRS) letters, 95% CI -1.17 to 0.07; 8 studies, 3603 participants; high-certainty evidence) and the proportion of participants who lost fewer than 15 letters in BCVA at 24 to 48 weeks (RR 0.99, 95% CI 0.98 to 1.01; 7 studies, 2658 participants; moderate-certainty evidence). Almost all participants (96.6% in the biosimilar group and 97.0% in the reference product group) lost fewer than 15 letters in BCVA. The evidence from two studies suggested that there was no evidence of difference between biosimilars and reference products in vision-related quality of life measured by the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) summary scores at 24 to 48 weeks (MD 0.82, 95% CI -0.70 to 2.35; 2 studies, 894 participants; moderate-certainty evidence). With regard to the safety profile, meta-analyses also revealed little to no difference between anti-VEGF biosimilars and the reference products for the proportion of participants who experienced serious ocular AEs (RR 1.24, 95% CI 0.68 to 2.26; 7 studies, 3292 participants; moderate-certainty evidence), and for TEAEs leading to investigational product discontinuation or death (RR 0.96, 95% CI 0.63 to 1.46; 8 studies, 3497 participants; moderate-certainty evidence). Overall, 1.4% of participants in the biosimilar group and 1.2% in the reference product group experienced serious ocular adverse events. The most frequently documented serious ocular AEs were retinal hemorrhage and endophthalmitis. Although the evidence is of low certainty due to imprecision, meta-analysis suggested that anti-VEGF biosimilars led to no difference compared with the reference products for cumulative incidence of ADAs (RR 0.84, 95% CI 0.58 to 1.22; 8 studies, 3066 participants; low-certainty evidence) or mean maximum serum concentrations (MD 0.42 ng/mL, 95% CI -0.22 to 1.05; subgroup of 3 studies, 100 participants; low-certainty evidence). We judged the overall risk of bias to be low for all studies. AUTHORS' CONCLUSIONS: In our review, low to high certainty evidence suggests that there is little to no difference, to date, between the anti-VEGF biosimilars approved for treating neovascular AMD and their reference products in terms of benefits and harms. While anti-VEGF biosimilars may be a viable alternative to reference products, current evidence for their use is based on a limited number of studies - particularly for comparison with aflibercept - with sparse long-term safety data, and infrequent assessment of quality of life outcomes. Our effect estimates and conclusions may be modified once findings have been reported from studies that are currently ongoing, and studies of biosimilar agents that are currently in development.

Clinical impact of a change in antibiotics or the addition of glycopeptide antibiotics for persistent febrile neutropenia after autologous stem cell transplantation.

BACKGROUND: A change in empirical antibiotics or the addition of glycopeptide antibiotics is often applied in cases of persistent febrile neutropenia (FN) despite the administration of broad-spectrum antibiotics. However, the clinical benefit of these approaches remains unclear. METHODS: We conducted a retrospective study to evaluate the effectiveness of a change in antibiotics or the addition of glycopeptide antibiotics for persistent FN after autologous hematopoietic cell transplantation (auto-HCT). We retrospectively reviewed the records of 208 patients who received auto-HCT at our institution between 2007 and 2019. FN that lasted for 4 days or longer was defined as persistent FN. We compared the time to defervescence between patients whose initial antibiotics were changed and/or who additionally received glycopeptide antibiotics, and those without these antibiotic modifications. RESULTS: Among patients who fulfilled the criteria of persistent FN (n = 125), changes in antibiotics were not significantly associated with the time to defervescence in a multivariate analysis (hazard ratio [HR] 0.72, p = 0.27). On the other hand, the addition of glycopeptide antibiotics was paradoxically associated with a delay in defervescence (HR 0.56, p = 0.033). CONCLUSIONS: Although there may be differences in patient backgrounds, no significant differences were observed in either a univariate or multivariate analysis. Since neither a change in antibiotics nor the addition of glycopeptide antibiotics was associated with earlier defervescence in persistent FN after auto-HCT, routine antibiotic modifications might not be necessary in this setting.

Efficacy of carbapenems and alternative antimicrobials for treating complicated urinary tract infections caused by third-generation cephalosporin-resistant gram-negative bacteria: A systematic review and meta-analysis of randomised controlled trials.

BACKGROUND: Specific data concerning the efficacy of alternative antibiotics for carbapenems against complicated urinary tract infections (cUTIs) attributed to antimicrobial-resistant (AMR) uropathogens are lacking. OBJECTIVES: This study aimed to assess the efficacy of carbapenems and non-carbapenem antibiotics in the clinical outcomes of cUTIs caused by AMR uropathogens. METHODS: In this systematic review and meta-analysis, databases, including MEDLINE/PubMed, the Cochrane Library, Embase and ClinicalTrials.gov, were searched. The study eligibility criteria were research articles conducted as randomised controlled trials that evaluated the composite outcomes of cUTIs. Participants were adult patients with cUTIs caused by gram-negative uropathogens resistant to third-generation cephalosporins. The intervention involved a non-carbapenem class of antimicrobial agents with in vitro activities against gram-negative uropathogens resistant to third-generation cephalosporins. Two independent researchers assessed the risk-of-bias using the second version of the Cochrane risk-of-bias tool for randomised trials. The treatment effects on each outcome were estimated as a risk ratio (RR) with a 95 % confidence interval (CI) using the random-effects model. Heterogeneity was assessed using the Cochrane Q-test and I2 statistics. RESULTS: Through database searches, 955 articles were retrieved. After screening the titles and abstracts, 52 articles were screened in full text. Finally, 12 studies met the inclusion criteria. No significant differences in efficacy were observed between alternative antibiotics and carbapenems (composite outcome, RR, 0.96; 95 % CI, 0.63-1.49; I2 = 21 %; low certainty of evidence). CONCLUSIONS: Alternative antibiotics had clinical efficacy similar to that of carbapenems for treating patients with cUTI caused by gram-negative uropathogens resistant to third-generation cephalosporins.

Effects of remote classes on the physical health of university students during the COVID-19 pandemic.

[Purpose] The purpose of this study is to determine how the study environment during remote classes affected the physical health of university students during the coronavirus disease 2019 pandemic. [Participants and Methods] A total of 3,359 students currently enrolled at our university participated anonymously. The survey was conducted using Google Forms, with items including "gender", "study environment during remote classes", "presence or absence of symptom", "symptoms that existed before starting remote classes", and "changes in symptoms after starting remote classes". [Results] The overall valid response rate was 49%, with a total of 688 males and 983 females providing responses. In the grouping by gender, the number of students with symptoms was significantly higher in females than in males. Similarly, the number of students with existing symptoms that were exacerbated was significantly higher in females than in males. With regards to study environment, a significantly higher proportion of students who sat on the floor during remote classes complained about exacerbated existing symptoms than those who sat on chairs. [Conclusion] The results demonstrate that remote classes during the coronavirus disease 2019 pandemic led to a higher prevalence of new physical symptoms and exacerbation of existing symptoms in females than in males, and when students sat on floors rather than on chairs.

Significance of Persistent Systemic Support in the Clinical Course of Delayed Post-hypoxic Leukoencephalopathy Following Severe Coronavirus Disease 2019.

A 45-year-old woman was hospitalized with severe coronavirus disease 2019 pneumonia. Following cytokine storm-induced multiorgan failure and lethal arrhythmia, the patient developed a sustained coma with flaccid quadriplegia. A cerebrospinal fluid examination excluded infectious and immunogenic encephalopathies, and diffusion-weighted magnetic resonance imaging demonstrated high-intensity areas in the white matter with a cortex-sparing distribution, suggesting delayed post-hypoxic leukoencephalopathy. As a result of intensive cardiopulmonary support for a month, the neurological function gradually recovered. Based on the reversible clinical course noted in this patient, accurate diagnosis and persistent medical approaches are important for the management of coronavirus disease 2019-related delayed post-hypoxic leukoencephalopathy.

Bleeding risk factors and real-world antithrombotic therapies in elderly patients with atrial fibrillation undergoing percutaneous coronary intervention: a retrospective study.

BACKGROUND: Bleeding risk factors in elderly patients with atrial fibrillation undergoing percutaneous coronary intervention (PCI) are unclear and data on the use of antithrombotic drugs are lacking. We investigated the bleeding risk factors in elderly patients with atrial fibrillation undergoing PCI to help optimize antithrombotic therapy according to bleeding risk. We also investigated the association between the actual use of antithrombotic therapy and bleeding events. METHODS: A retrospective cohort study was conducted on 134 elderly patients with atrial fibrillation who underwent primary PCI at the Department of Cardiology, Showa University Fujigaoka Hospital. The endpoint was a bleeding event within 1-year. Bleeding risk factors were identified using multivariate analysis. The association between the number of antithrombotics and bleeding events was evaluated using the chi-squared test. RESULTS: The mean age of the patients was 76.0 ± 6.2 years. Bleeding events occurred in 41 (30.6%) patients. Age > 80 years (odds ratio [OR]: 2.54, 95% confidence interval [CI]: 1.10-5.85), multivessel disease (OR: 2.76, 95% CI: 1.22-6.23), and history of surgery (OR: 3.03, 95% CI: 1.14-8.06) were identified as bleeding risk factors. The proportion of patients receiving triple therapy was significantly higher in the bleeding group compared to the non-bleeding group (70.7% vs. 27.5%, p < 0.001). CONCLUSIONS: Age > 80, multivessel disease, and history of surgery were found to be risk factors for bleeding in elderly patients with atrial fibrillation undergoing PCI. In addition, dual therapy after PCI in elderly patients at high risk of bleeding should be considered to avoid bleeding events.

Efficacy and safety of drug therapy for the prevention and treatment of chemotherapy-induced peripheral neuropathy: a protocol for a systematic review and network meta-analysis.

INTRODUCTION: Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common dose-limiting side effects of chemotherapeutic drugs. Numerous clinical trials of various targeted drugs for the prevention or treatment of CIPN have been conducted; however, previous systematic reviews with direct comparisons have failed to demonstrate the efficacy of these drugs in the prevention or treatment of CIPN. In addition, no systematic reviews have indirectly compared CIPN prevention and treatment. This article describes a protocol for evaluating the efficacy and safety of drug therapy for the prevention and treatment of CIPN. The results of the proposed systematic review with network meta-analysis (NMA) will provide new insights into the prevention and treatment of CIPN. METHODS AND ANALYSIS: We will conduct a literature search in MEDLINE, PubMed, Embase, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov to find relevant articles published through January 2023. We will include studies that investigated the efficacy and safety of vitamin B12, goshajinkigan, non-steroidal anti-inflammatory analgesics, opioids, calcium and magnesium, antidepressants and anticonvulsants on CIPN. Two authors will individually screen the retrieved reports and review the full text based on the selection criteria. The primary outcome is the incidence and severity of CIPN. The risk of bias will be assessed using V.2.0 of the Cochrane risk-of-bias tool. We will apply a frequentist random-effects NMA model to pool effect sizes across trials using risk ratios and mean differences with their 95% CIs. Competing interventions will be ranked using the surface under cumulative ranking probabilities. Heterogeneity will be assessed using the heterogeneity variance τ2, Cochran's Q test and I² statistic. ETHICS AND DISSEMINATION: This review does not require ethical approval. The research will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42022371829.

Clinical Impact of Pretransplantation Physical Function on Transplantation after Allogeneic Hematopoietic Cell Transplantation in Older Adults.

Clinical research regarding the impact of pretransplantation physical function on transplantation outcomes in older adults remains limited. We retrospectively reviewed the charts of 150 consecutive patients age >55 years who underwent their first allogeneic hematopoietic cell transplantation (HCT) at our center between 2010 and 2021. We evaluated the clinical impact of pretransplantation physical function, including hand grip strength (HGS), knee extension strength (KES), and distance covered in a 6-minute walk test (6MWT), along with other clinical factors, on transplantation outcomes such as overall survival (OS), nonrelapse mortality (NRM), and cumulative incidence of disease relapse (CIR). There was no difference in OS, NRM, or CIR among the 3 age groups studied (56 to 60 years, 61 to 65 years, and 66 to 70 years). With regard to physical function tests, we divided the study patients into 2 groups based on the median HGS, KES, and 6MWT values: higher physical function and lower physical function groups. Because there were significant differences in HGS and KES between male and female patients, sex-specific threshold values were used. In a univariate analysis, OS tended to be better in the higher physical function group compared with the lower physical function group (4-year OS, 42.0% versus 32.0% in HGS, P = .14; 44.8% versus 37.8% in KES, P = .17; 46.7% versus 30.5% in 6MWT, P = .099). NRM was significantly lower in the higher physical function group (4-year NRM, 25.5% versus 39.9% in HGS, P = .045; 17.7% versus 38.0% in KES, P = .005; 22.5% versus 43.4% in 6MWT, P = .033). There was no significant difference in CIR between the higher and lower physical function groups (4-year CIR, 34.6% versus 28.7% in HGS, P = .38; 38.5% versus 25.8% in KES, P = .20; 33.0% versus 27.0% in 6MWT, P = .42). In multivariate analysis, the higher KES group (hazard ratio [HR], .54; 95% confidence interval [CI], .32 to .90) was significantly associated with better OS, as were female sex (HR, .48; 95% CI, .26 to .89) and low/intermediate Disease Risk Index (HR, 3.59; 95% CI, 2.04 to 6.31). Higher KES (HR, .37; 95% CI, .17 to .83) and female sex (HR .36; 95% CI, .13 to .998) were significantly associated with a reduced risk of NRM. Higher HGS and higher 6MWT tended to be associated with a reduced risk of NRM, but this trend was not statistically significant. Pretransplantation physical function, particularly the strength of the lower extremities, but not chronological age, is associated with NRM and OS after allogeneic HCT in adults age >55 years.

Substitution of calcineurin inhibitors with corticosteroids after allogeneic hematopoietic cell transplantation.

Combination of calcineurin inhibitors (CIs) with short-term methotrexate is a standard prophylactic regimen for graft-versus-host disease (GVHD). However, it is sometimes difficult to continue CIs due to adverse effects, such as renal impairment and fluid overload. In such cases, we replace CIs with corticosteroids, considering that full dose of CIs is equivalent to prednisolone (PSL) at 1 mg/kg. We retrospectively evaluated the clinical significance of replacement of CIs with corticosteroids after allogeneic hematopoietic cell transplantation (HCT). We evaluated 42 patients switched from CIs to corticosteroids within 90 days among the 479 patients who underwent allogeneic HCT at our center between 2007 and 2019. Renal impairment (n = 33), fluid overload (n = 13), and thrombotic microangiopathy (n = 3) were the main reasons for switching. Although creatinine and body weight returned to baseline at 4 weeks after switching, 100-day non-relapse mortality was high (57.1%). Grade II-IV acute GVHD was seen in 10 (24.4%) patients who did not have it before switching treatment (n = 41). In conclusion, CIs were switched to corticosteroids in patients with severe clinical conditions. The incidence of acute GVHD was acceptable. Although the short-term mortality rate was high, improvement of renal function or fluid overload was observed in a certain proportion of the patients.

New Web-Based System for Recording Public Health Nursing Practices and Determining Best Practices: Protocol of an Exploratory Sequential Design.

BACKGROUND: Digitalization and information and communication technology (ICT) promote effective, efficient individual and community care. Clinical terminology or taxonomy and its framework visualize individual patients' and nursing interventions' classifications to improve their outcomes and care quality. Public health nurses (PHNs) provide lifelong individual care and community-based activities while developing projects to promote community health. The linkage between these practices and clinical assessment remains tacit. Owing to Japan's lagging digitalization, supervisory PHNs face difficulties in monitoring each department's activities and staff members' performances and competencies. Randomly selected prefectural or municipal PHNs collect data on daily activities and required hours every 3 years. No study has adopted these data for public health nursing care management. PHNs need ICTs to manage their work and improve care quality; it may help identify health needs and suggest best public health nursing practices. OBJECTIVE: We aim to develop and validate an electronic recording and management system for evaluating different public health nursing practice needs, including individual care, community-based activities, and project development, and for determining their best practices. METHODS: We used a 2-phase exploratory sequential design (in Japan) comprising 2 phases. In phase 1, we developed the system's architectural framework and a hypothetical algorithm to determine the need for practice review through a literature review and a panel discussion. We designed a cloud-based practice recording system, including a daily record system and a termly review system. The panels included 3 supervisors who were prior PHNs at the prefectural or municipal government, and 1 was the executive director of the Japanese Nursing Association. The panels agreed that the draft architectural framework and hypothetical algorithm were reasonable. The system was not linked to electronic nursing records to protect patient privacy. Phase 2 validated each item through interviews with supervisory PHNs using a web-based meeting system. A nationwide survey was distributed to supervisory and midcareer PHNs across local governments. RESULTS: This study was funded in March 2022 and approved by all ethics review boards from July to September and November 2022. Data collection was completed in January 2023. Five PHNs participated in the interviews. In the nationwide survey, responses were obtained from 177 local governments of supervisory PHNs and 196 midcareer ones. CONCLUSIONS: This study will reveal PHNs' tacit knowledge about their practices, assess needs for different approaches, and determine best practices. Additionally, this study will promote ICT-based practices in public health nursing. The system will enable PHNs to record their daily activities and share them with their supervisors to reflect on and improve their performance, and the quality of care to promote health equity in community settings. The system will support supervisory PHNs in creating performance benchmarks for their staff and departments to promote evidence-based human resource development and management.

Comparison of changes in thigh circumference during the menstrual cycle between female transfemoral amputees and non-amputee females: examination of the reliability and comparison of diurnal and day-to-day fluctuations.

[Purpose] Few studies have investigated diurnal and day-to-day changes in the thigh circumference of the residual limb in female amputees. In this study, we used a limb circumference measuring device to confirm the reliability of the measurement and compared the changes in the measured values over time. [Participants and Methods] The study measured and compared the femoral circumference in 2 female amputees and 8 healthy female non-amputees in the morning and evening. [Results] Reliability was assured by measuring the circumferential diameter in triplicate. There were no significant interactions in both diurnal and day-to-day variations, however, in both variations, there were significant differences in the femoral circumstance at any site among the non-amputees. [Conclusion] The amount of edema increased in the evening and varied from day to day in the non-amputees.

Development of a model predicting cardiac events in heart failure patients with decreased renal function: a retrospective study.

BACKGROUND: Inappropriate and multiple medications affect the prognosis of patients with acute decompensated heart failure (ADHF). However, in ADHF patients with decreased renal function, there have been no reports on prognostic factors, including medication data, or models for predicting cardiac events. AIM: To develop a model including medication data to predict cardiac events in ADHF patients with decreased renal function. METHOD: This retrospective cohort study included 443 first-time admitted ADHF patients with decreased renal function (estimated glomerular filtration rate < 60 mL/min/1.73 m2 at discharge) in the Showa University Fujigaoka Hospital. The primary outcome was cardiac events within one year after discharge, defined as the composite of HF readmission, HF mortality, and cardiovascular mortality. The model for predicting cardiac events was developed using predictive factors extracted by multivariable analysis. The cardiac events curves were visualized using the Kaplan-Meier method and estimated using a log-rank test. RESULTS: The incidence of cardiac events within one year after discharge was 20.1%. By multivariable analysis, we observed that atrial fibrillation, weight loss < 5%, brain natriuretic peptide ≥ 200 pg/mL, polypharmacy, and beta-blockers use below target dosage were significantly associated with an increased risk of cardiac events. The developed model, the cardiac events rate in the high-risk group was significantly higher than in the low-risk group (41.0 vs. 9.2%, p < 0.001). CONCLUSION: The developed model for predicting cardiac events will be useful in decision-making to support appropriate early management of ADHF patients with decreased renal function.

Chronic active Epstein-Bar virus infection complicated by pulmonary artery hypertension.

Chronic active Epstein-Bar virus infection (CAEBV) is known to cause various symptoms. Although pulmonary artery hypertension (PAH) has been reported as a cardiovascular complication of CAEBV, the mechanisms of PAH and the effects of treatment have not been fully elucidated. We experienced 4 adult patients with CAEBV complicated by PAH. All of them received treatment for PAH with a vasodilator followed by chemotherapy with or without allogeneic hematopoietic cell transplantation for CAEBV. In all of these patients, the transtricuspid pressure gradient improved under treatment with vasodilator, and further improvement was observed under treatment for CAEBV in 3 patients. Autopsy was performed in 2 patients, which revealed EBER-positive cells and a change in the pulmonary artery at each stage in the pathology. In conclusion, EBV-infected cells can cause vasculitis and finally PAH. However, PAH complicated with CAEBV can be improved by PAH medication and treatment of CAEBV.

Predictive Factors of Febrile Neutropenia After Primary Prophylactic Pegfilgrastim With DCF Chemotherapy for Esophageal Cancer.

BACKGROUND/AIM: We investigated the predictive factors of febrile neutropenia (FN) after the administration of pegfilgrastim as primary prophylaxis in patients with esophageal cancer who received neoadjuvant chemotherapy with docetaxel, cisplatin, and 5-fluorouracil (DCF) to support the appropriate management of FN. We evaluated changes in neutrophil counts and relative dose intensity (RDI) after the incidence of FN. PATIENTS AND METHODS: This retrospective study involved 122 patients with esophageal cancer who were treated with DCF and pegfilgrastim at Showa University Hospital, Japan, between April 2016 and August 2021. The primary outcome was FN incidence after cycle 1 of DCF chemotherapy. The significant independent factors associated with FN incidence were selected using the multivariate analysis. Changes in neutrophil counts and RDI were compared between the FN and non-FN groups. RESULTS: One-hundred patients were included in the analysis. The incidence of FN in cycle 1 was 21%. In the multivariate analysis, geriatric nutritional risk index (GNRI) <92 [odds ratio (OR)=13.162, p<0.001] and combination of platelet and neutrophil-to-lymphocyte ratio (COP-NLR) score of 0 (OR=4.619, p=0.012) were independent predictors of FN. The neutrophil count on day 7-10 and RDI in the FN group were lower than those in the non-FN group (all p<0.05). CONCLUSION: GNRI <92 and COP-NLR score of 0 are important indicators to predict patients at high risk of DCF chemotherapy-induced FN. Furthermore, FN incidence after pegfilgrastim administration had a strong effect on delayed neutrophil recovery and reduced RDI.

Chromatin remodeler CHD7 targets active enhancer region to regulate cell type-specific gene expression in human neural crest cells.

A mutation in the chromatin remodeler chromodomain helicase DNA-binding 7 (CHD7) gene causes the multiple congenital anomaly CHARGE syndrome. The craniofacial anomalies observed in CHARGE syndrome are caused by dysfunctions of neural crest cells (NCCs), which originate from the neural tube. However, the mechanism by which CHD7 regulates the function of human NCCs (hNCCs) remains unclear. We aimed to characterize the cis-regulatory elements governed by CHD7 in hNCCs by analyzing genome-wide ChIP-Seq data and identifying hNCC-specific CHD7-binding profiles. We compared CHD7-binding regions among cell types, including human induced pluripotent stem cells and human neuroepithelial cells, to determine the comprehensive properties of CHD7-binding in hNCCs. Importantly, analysis of the hNCC-specific CHD7-bound region revealed transcription factor AP-2α as a potential co-factor facilitating the cell type-specific transcriptional program in hNCCs. CHD7 was strongly associated with active enhancer regions, permitting the expression of hNCC-specific genes to sustain the function of hNCCs. Our findings reveal the regulatory mechanisms of CHD7 in hNCCs, thus providing additional information regarding the transcriptional programs in hNCCs.

Prognostic model for overall survival that includes the combination of platelet count and neutrophil-lymphocyte ratio within the first six weeks of sunitinib treatment for metastatic renal cell carcinoma.

BACKGROUND: The association between the combination of platelet count and neutrophil-lymphocyte ratio (COP-NLR) at the time of adverse events during sunitinib treatment and prognosis is unclear, and prognostic models combining the prognostic factors of sunitinib have not been well studied. Thus, we developed a prognostic model that includes the COP-NLR to predict the prognosis of patients with metastatic renal cell carcinoma (mRCC) treated with sunitinib. METHODS: We performed a retrospective cohort study of 102 patients treated with sunitinib for mRCC between 2008 and 2020 in three hospitals associated with Showa University, Japan. The primary outcome was overall survival (OS). The collected data included baseline patient characteristics, adverse events, laboratory values, and COP-NLR scores within the first 6 weeks of sunitinib treatment. Prognostic factors of OS were analyzed using the Cox proportional hazards model. The integer score was derived from the beta-coefficient (ß) of these factors and was divided into three groups. The survival curves were visualized using the Kaplan-Meier method and estimated using a log-rank test. RESULTS: The median OS was 32.3 months. Multivariable analysis showed that the number of metastatic sites, Memorial Sloan Kettering Cancer Center risk group, number of metastases, non-hypertension, modified Glasgow Prognostic Score, and 6-week COP-NLR were significantly associated with OS. A higher 6-week COP-NLR was significantly associated with a shorter OS (p < 0.001). The ß values of the five factors for OS were scored (non-hypertension, mGPS, and 6-week COP-NLR = 1 point; number of metastatic sites = 2 points; MSKCC risk group = 3 points) and patients divided into three groups (≤ 1, 2-3, and ≥ 4). The low-risk (≤ 1) group had significantly longer OS than the high-risk (≥ 4) group (median OS: 99.0 vs. 6.2 months, p < 0.001). CONCLUSIONS: This study showed that the COP-NLR within the first 6 weeks of sunitinib treatment had a greater impact on OS than the COP-NLR at the start of sunitinib treatment. The developed prognostic model for OS, including the 6-week COP-NLR, will be useful in decision-making to continue sunitinib in the early treatment stage of patients with mRCC.

Two Cases of Acute Urinary Retention Associated With Acute Sarcopenia in Older Women.

Acute urinary retention during hospitalization is a poor prognostic predictor. Therefore, prevention of the same is important. Herein, we describe two cases of acute urinary retention in older women admitted to the hospital for acute illness, with severe sarcopenia being the only predisposing cause. Both women developed urinary problems shortly after admission. In both, acute urinary retention was preceded by an in-hospital period of poor nutritional intake and a lack of progress in rehabilitation. There was no evidence of genitourinary disorder, neurological disease, drug-induced dysuria, bone fracture, or pain. Both patients presented with severe sarcopenia and severe frailty.Although the loss of mass in the voiding muscles is difficult to detect, the possibility of dysuria as one of the complications of acute and severe sarcopenia was indicated in our patients. Of note, however, is that many patients with severe sarcopenia do not develop dysuria. Therefore, accumulating evidence on the possible association between severe sarcopenia and dysuria is needed to inform prevention.

Comparison of the impact of two post-remission therapy regimens on cardiac events in acute myeloid leukemia patients undergoing allogeneic hematopoietic stem cell transplantation.

High-dose cytarabine (HD-AraC) or anthracycline-containing chemotherapies are used as post-remission therapy for acute myeloid leukemia (AML) patients. However, it remains unclear which regimen would be better as post-remission therapy before allogeneic hematopoietic stem cell transplantation (allo-HSCT). Thus, we compared the incidence of cardiac events and event-free survival (EFS) after allo-HSCT at two Japanese hospitals between HD-AraC and anthracycline-containing post-remission therapy to clarify the safety of post-remission therapy. Of a total of 132 patients, 68 received HD-AraC (HD-AraC group) and 64 received anthracycline-containing chemotherapy (ANT group). HD-AraC was preferentially selected for core-binding factor AML patients (p = 0.008). The median cumulative anthracycline dose was 115.2 mg/m2 in the HD-AraC group and 318.7 mg/m2 in the ANT group (p < 0.0001). Cardiac events were observed in 18 (13.6%) patients during the follow-up period. The 3-year cumulative incidence of cardiac events was 9.1% in the HD-AraC group and 11.0% in the ANT group (p = 0.70). EFS at 3 years after allo-HSCT was 40.9% in the HD-AraC group and 39.6% in the ANT group (p = 0.51). In conclusion, incidence of cardiac events did not differ significantly between post-remission therapy regimens in AML patients who underwent allo-HSCT.
