Hospital Strain During the COVID-19 Pandemic and Outcomes in Older Racial and Ethnic Minority Adults.

Importance: Marginalized populations have been disproportionately affected by the COVID-19 pandemic. Critically ill patients belonging to racial and ethnic minority populations treated in hospitals operating under crisis or near-crisis conditions may have experienced worse outcomes than White individuals. Objective: To examine whether hospital strain was associated with worse outcomes for older patients hospitalized with sepsis and whether these increases in poor outcomes were greater for members of racial and ethnic minority groups compared with White individuals. Design, Setting, and Participants: In this cross-sectional study, multivariable regression analysis was conducted to assess differential changes in all-cause 30-day mortality and major morbidity among older racial and ethnic minoritized individuals hospitalized with sepsis compared with White individuals and changes in hospital strain using Medicare claims data. Data were obtained on patients hospitalized between January 1, 2016, and December 31, 2021, and analyzed between December 16, 2023, and July 11, 2024. Exposure: Time-varying weekly hospital percentage of inpatients with COVID-19. Main Outcomes and Measures: Composite of all-cause 30-day mortality and major morbidity. Results: Among the 5 899 869 hospitalizations for sepsis (51.5% women; mean [SD] age, 78.2 [8.8] years), there were 177 864 (3.0%) Asian, 664 648 (11.3%) Black, 522 964 (8.9%) Hispanic, and 4 534 393 (76.9%) White individuals. During weeks when the hospital COVID-19 burden was greater than 40%, the risk of death or major morbidity increased nearly 2-fold (adjusted odds ratio [AOR], 1.90; 95% CI, 1.80-2.00; P < .001) for White individuals compared with before the pandemic. Asian, Black, and Hispanic individuals experienced 44% (AOR, 1.44; 95% CI, 1.28-1.61; P < .001), 21% (AOR, 1.21; 95% CI, 1.11-1.33; P < .001), and 45% (AOR, 1.45; 95% CI, 1.32-1.59; P < .001) higher risk of death or morbidity, respectively, compared with White individuals when the hospital weekly COVID-19 burden was greater than 40%. Conclusion and Relevance: In this cross-sectional study, older adults hospitalized with sepsis were more likely to die or experience major morbidity as the hospital COVID-19 burden increased. These increases in adverse outcomes were greater in magnitude among members of minority populations than for White individuals.

Development of a Symptom Self-Management Guide for Older Chinese Americans Kidney Receiving Replacement Therapy.

Aim: To assess the acceptability of a symptom self-management booklet among older Chinese Americans receiving kidney replacement therapy. Background: In previous work, we identified commonly occurring, bothersome symptoms and strategies used in this population to ameliorate symptoms. We used these data to develop a symptom self-management booklet in English, traditional, and simplified Chinese. Introduction: In the United States, the prevalence of kidney disease is 1.5 times higher in Asians compared to whites. With the many symptoms associated with this disease, self-management of symptoms would be particularly helpful. Methods: Seven older Chinese Americans receiving kidney replacement therapy and their caregivers were interviewed to assess the acceptability of the booklets. We reviewed participant feedback on content, graphics, and design, reading experience, suggestions for improvement, and health information sources using the inductive thematic method. Results: Overall, patients confirmed acceptability of these self-management booklets across all domains. Discussion. This study validated the booklet as a source of health information for older Chinese American patients with kidney disease, which some studies suggest are preferred to electronic materials or methods in this population. Health care providers can use the resultant booklets when caring for these patients to provide culturally sensitive information on self-management of symptoms. Conclusion and Implications for Nursing. These booklets provide a free resource tailored to an underserved population and may help nurses and nurse practitioners provide care with cultural humility. Implications for Health Policy. Embracing community-based participatory research, as was done in this study, can help create culturally appropriate patient education materials that empower patient symptom self-management and promote informative and culturally sensitive conversations between patients, families, and providers.

Post-Acute Care Trends and Disparities After Joint Replacements in the United States, 1991-2018: A Systematic Review.

OBJECTIVE: To review evidence on post-acute care (PAC) use and disparities related to race and ethnicity and rurality in the United States over the past 2 decades among individuals who underwent major joint replacement (MJR). DESIGN: Systematic review. SETTING AND PARTICIPANTS: We included studies that examined US PAC trends and racial and ethnic and/or urban vs rural differences among individuals who are aged ≥18 years with hospitalization after MJR. METHODS: We searched large academic databases (PubMed, CINAHL, Embase, Web of Science, and Scopus) for peer-reviewed, English language articles from January 1, 2000, and January 26, 2022. RESULTS: Seventeen studies were reviewed. Studies (n = 16) consistently demonstrated that discharges post-MJR to skilled nursing facilities (SNFs) or nursing homes (NHs) decreased over time, whereas evidence on discharges to inpatient rehab facilities (IRFs), home health care (HHC), and home without HHC services were mixed. Most studies (n = 12) found that racial and ethnic minority individuals, especially Black individuals, were more frequently discharged to PAC institutions than white individuals. Demographic factors (ie, age, sex, comorbidities) and marital status were not only independently associated with discharges to institutional PAC, but also among racial and ethnic minority individuals. Only one study found urban-rural differences in PAC use, indicating that urban-dwelling individuals were more often discharged to both SNF/NH and HHC than their rural counterparts. CONCLUSIONS AND IMPLICATIONS: Despite declines in institutional PAC use post-MJR over time, racial and minority individuals continue to experience higher rates of institutional PAC discharges compared with white individuals. To address these disparities, policymakers should consider measures that target multimorbidity and the lack of social and structural support among socially vulnerable individuals. Policymakers should also consider initiatives that address the economic and structural barriers experienced in rural areas by expanding access to telehealth and through improved care coordination.

[Aging and Small-sized Particles Release Characteristics of Tire Microplastics in Various Environmental Media].

In recent years, research on microplastics has mostly focused on thermoplastic materials, and there is a lack of research on the pollution status and environmental behavior of tire microplastics, a type of rubber elastomers. In order to investigate the aging and small-sized particles release characteristics of tire microplastics in various environmental media, the aging process of two different tire microplastics, one for cars and the other for electric bicycles, was simulated in dry and aquatic environments under laboratory conditions. The results showed that the tire microplastics would be aged after 30 d of UV illumination, which was manifested by the roughness of the surface and the appearance of cracks and flaking. The Fourier infrared spectra showed that the carbonyl index of the surface also increased. In addition, tire microplastics released a large number of small sub-micron particles under the influence of UV illumination and hydrodynamic action, and the number of particles released from car tire microplastics in aquatic environments reached 694.8 million particles per milliliter of solution at 30 d of the UV light condition, among which 694.6 million particles with a particle size of less than 1 µm were released, which was approximately 100 times of that in the dark condition. The study showed that tire microplastics in aquatic environments were more susceptible to aging and released more small particles under light conditions and that car tire microplastics released more small particles than electric bicycle tire microplastics, posing ecological and environmental risks.

Natural Language Processing to Identify Home Health Care Patients at Risk for Becoming Incapacitated With No Evident Advance Directives or Surrogates.

OBJECTIVES: Home health care patients who are at risk for becoming Incapacitated with No Evident Advance Directives or Surrogates (INEADS) may benefit from timely intervention to assist them with advance care planning. This study aimed to develop natural language processing algorithms for identifying home care patients who do not have advance directives, family members, or close social contacts who can serve as surrogate decision-makers in the event that they lose decisional capacity. DESIGN: Cross-sectional study of electronic health records. SETTING AND PARTICIPANTS: Patients receiving post-acute care discharge services from a large home health agency in New York City in 2019 (n = 45,390 enrollment episodes). METHODS: We developed a natural language processing algorithm for identifying information documented in free-text clinical notes (n = 1,429,030 notes) related to 4 categories: evidence of close relationships, evidence of advance directives, evidence suggesting lack of close relationships, and evidence suggesting lack of advance directives. We validated the algorithm against Gold Standard clinician review for 50 patients (n = 314 notes) to calculate precision, recall, and F-score. RESULTS: Algorithm performance for identifying text related to the 4 categories was excellent (average F-score = 0.91), with the best results for "evidence of close relationships" (F-score = 0.99) and the worst results for "evidence of advance directives" (F-score = 0.86). The algorithm identified 22% of all clinical notes (313,290 of 1,429,030) as having text related to 1 or more categories. More than 98% of enrollment episodes (48,164 of 49,141) included at least 1 clinical note containing text related to 1 or more categories. CONCLUSIONS AND IMPLICATIONS: This study establishes the feasibility of creating an automated screening algorithm to aid home health care agencies with identifying patients at risk of becoming INEADS. This screening algorithm can be applied as part of a multipronged approach to facilitate clinician support for advance care planning with patients at risk of becoming INEADS.

Explore the shared molecular mechanism between dermatomyositis and nasopharyngeal cancer by bioinformatic analysis.

BACKGROUND: Dermatomyositis (DM) is prone to nasopharyngeal carcinoma (NPC), but the mechanism is unclear. This study aimed to explore the potential pathogenesis of DM and NPC. METHODS: The datasets GSE46239, GSE142807, GSE12452, and GSE53819 were downloaded from the GEO dataset. The disease co-expression module was obtained by R-package WGCNA. We built PPI networks for the key modules. ClueGO was used to analyze functional enrichment for the key modules. DEG analysis was performed with the R-package "limma". R-package "pROC" was applied to assess the diagnostic performance of hub genes. MiRNA-mRNA networks were constructed using MiRTarBase and miRWalk databases. RESULTS: The key modules that positively correlated with NPC and DM were found. Its intersecting genes were enriched in the negative regulation of viral gene replication pathway. Similarly, overlapping down-regulated DEGs in DM and NPC were also enriched in negatively regulated viral gene replication. Finally, we identified 10 hub genes that primarily regulate viral biological processes and type I interferon responses. Four key genes (GBP1, IFIH1, IFIT3, BST2) showed strong diagnostic performance, with AUC>0.8. In both DM and NPC, the expression of key genes was correlated with macrophage infiltration level. Based on hub genes' miRNA-mRNA network, hsa-miR-146a plays a vital role in DM-associated NPC. CONCLUSIONS: Our research discovered pivot genes between DM and NPC. Viral gene replication and response to type I interferon may be the crucial bridge between DM and NPC. By regulating hub genes, MiR-146a will provide new strategies for diagnosis and treatment in DM complicated by NPC patients. For individuals with persistent viral replication in DM, screening for nasopharyngeal cancer is necessary.

[Effect of Recombinant Human Thrombopoietin on Platelet Reconstitution after Autologous Peripheral Blood Stem Cell Transplantation in Patients with Multiple Myeloma].

OBJECTIVE: To analyze the effect of recombinant human thrombopoietin (rhTPO) on platelet (PLT) reconstitution after autologous peripheral blood stem cell transplantation (APBSCT) in patients with multiple myeloma (MM). METHODS: The clinical data of 147 MM patients who were diagnosed in the First Affiliated Hospital of Soochow University and received APBSCT as the first-line therapy were retrospectively analyzed. According to whether rhTPO was used during APBSCT, the patients were divided into rhTPO group (80 cases) and control group (67 cases). The time of PLT engraftment, blood product infusion requirements, the proportion of patients with PLT recovery to≥50×109/L and≥100×109/L at +14 days and +100 days after transplantation, and adverse reactions including the incidence of bleeding were compared between the two groups. RESULTS: There were no significant differences between the two groups in sex, age, M protein type, PLT count at the initial diagnosis, median duration of induction therapy before APBSCT, and number of CD34+ cells reinfused (all P >0.05). The median time of PLT engraftment in the rhTPO group was 10 (6-14) days, which was shorter than 11 (8-23) days in the control group (P < 0.001). The median PLT transfusion requirement in the rhTPO group during APBSCT was 15(0-50)U, which was less than 20 (0-80)U in the control group (P =0.001). At +14 days after transplantation, the proportions of patients with PLT≥50×109/L in the rhTPO group and the control group were 66.3% and 52.2%, while the proportions of patients with PLT≥100×109/L were 23.8% and 11.9%, respectively, with no significant differences (all P >0.05). At +100 days after transplantation, the proportion of patients with PLT≥50×109/L in rhTPO group and control group was 96.3% and 89.6%, respectively (P >0.05), but the proportion of patients with PLT≥100×109/L in rhTPO group was higher than that in control group (75.0% vs 55.2%, P =0.012). There was no difference in the overall incidence of bleeding events in different locations during period of low PLT level of patients between the two groups. In rhTPO group, the rhTPO administration was well tolerated, and the incidences of abnormal liver and kidney function and infection were similar to those in the control group. CONCLUSION: When MM patients undergo first-line APBSCT, subcutaneous injection of rhTPO can shorten the time of platelet engraftment, reduce the transfusion volume of blood products, and be well tolerated, moreover, more patients have achieve a high level of PLT recovery after transplantation, which is very important for ensuring the safety of APBSCT and maintenance therapy.

Insurance-based Disparities in Outcomes and Extracorporeal Membrane Oxygenation Utilization for Hospitalized COVID-19 Patients.

BACKGROUND: The objective of this study was to examine insurance-based disparities in mortality, nonhome discharges, and extracorporeal membrane oxygenation utilization in patients hospitalized with COVID-19. METHODS: Using a national database of U.S. academic medical centers and their affiliated hospitals, the risk-adjusted association between mortality, nonhome discharge, and extracorporeal membrane oxygenation utilization and (1) the type of insurance coverage (private insurance, Medicare, dual enrollment in Medicare and Medicaid, and no insurance) and (2) the weekly hospital COVID-19 burden (0 to 5.0%; 5.1 to 10%, 10.1 to 20%, 20.1 to 30%, and 30.1% and greater) was evaluated. Modeling was expanded to include an interaction between payer status and the weekly hospital COVID-19 burden to examine whether the lack of private insurance was associated with increases in disparities as the COVID-19 burden increased. RESULTS: Among 760,846 patients hospitalized with COVID-19, 214,992 had private insurance, 318,624 had Medicare, 96,192 were dually enrolled in Medicare and Medicaid, 107,548 had Medicaid, and 23,560 had no insurance. Overall, 76,250 died, 211,702 had nonhome discharges, 75,703 were mechanically ventilated, and 2,642 underwent extracorporeal membrane oxygenation. The adjusted odds of death were higher in patients with Medicare (adjusted odds ratio, 1.28 [95% CI, 1.21 to 1.35]; P < 0.0005), dually enrolled (adjusted odds ratio, 1.39 [95% CI, 1.30 to 1.50]; P < 0.0005), Medicaid (adjusted odds ratio, 1.28 [95% CI, 1.20 to 1.36]; P < 0.0005), and no insurance (adjusted odds ratio, 1.43 [95% CI, 1.26 to 1.62]; P < 0.0005) compared to patients with private insurance. Patients with Medicare (adjusted odds ratio, 0.47; [95% CI, 0.39 to 0.58]; P < 0.0005), dually enrolled (adjusted odds ratio, 0.32 [95% CI, 0.24 to 0.43]; P < 0.0005), Medicaid (adjusted odds ratio, 0.70 [95% CI, 0.62 to 0.79]; P < 0.0005), and no insurance (adjusted odds ratio, 0.40 [95% CI, 0.29 to 0.56]; P < 0.001) were less likely to be placed on extracorporeal membrane oxygenation than patients with private insurance. Mortality, nonhome discharges, and extracorporeal membrane oxygenation utilization did not change significantly more in patients with private insurance compared to patients without private insurance as the COVID-19 burden increased. CONCLUSIONS: Among patients with COVID-19, insurance-based disparities in mortality, nonhome discharges, and extracorporeal membrane oxygenation utilization were substantial, but these disparities did not increase as the hospital COVID-19 burden increased.

Evaluation of next-generation sequencing versus next-generation flow cytometry for minimal-residual-disease detection in Chinese patients with multiple myeloma.

PURPOSE: To evaluate the efficacy of next-generation sequencing (NGS) in minimal-residual-disease (MRD) monitoring in Chinese patients with multiple myeloma (MM). METHODS: This study analyzed 60 Chinese MM patients. During MRD monitoring in these patients' post-therapy, clonal immunoglobulin heavy chain (IGH) rearrangements were detected via NGS using LymphoTrack assays. MRD monitoring was performed using NGS or next-generation flow cytometry (NGF), and the results were compared. Additionally, the sensitivity and reproducibility of the NGS method were assessed. RESULTS: The MRD detection range of the NGS method was 10-6-10-1, which suggested good linearity, with a Pearson correlation coefficient of 0.985 and a limit of detection of 10-6. Intra- and inter-assay reproducibility analyses showed that NGS exhibited 100% reproducibility with low variability in clonal cells. At diagnosis, unique clones were found in 42 patients (70.0%) with clonal IGH rearrangements, which were used as clonality markers for MRD monitoring post-therapy. Comparison of NGS and NGF for MRD monitoring showed 79.1% concordance. No samples that tested MRD-positive via NGF were found negative via NGS, indicating the higher sensitivity of NGS. MRD could be detected using NGS in 6 of 7 samples before autologous hematopoietic stem-cell transplantation, and 5 of them tested negative post-transplantation. In contrast, the NGF method could detect MRD in only 1 sample pre-transplantation. CONCLUSION: Compared with NGF, NGS exhibits higher sensitivity and reproducibility in MRD detection and can be an effective strategy for MRD monitoring in Chinese MM patients.

Home Care Clinicians' Perspectives on Advance Care Planning for Patients at Risk for Becoming Incapacitated With No Evident Advance Directives or Surrogates.

Advance care planning is important and timely for patients receiving home health services; however, opportunities to facilitate awareness and engagement in this setting are often missed. This qualitative descriptive study elicited perspectives of home health nurses and social workers regarding barriers and facilitators to creating advance care plans in home health settings, with particular attention to patients with few familial or social contacts who can serve as surrogate decision-makers. We interviewed 15 clinicians employed in a large New York City-based home care agency in 2021-2022. Participants reported a multitude of barriers to supporting patients with advance care planning at the provider level (eg, lack of time and professional education, deferment, discomfort), patient level (lack of knowledge, mistrust, inadequate support, deferment, language barriers), and system level (eg, discontinuity of care, variations in advance care planning documents, legal concerns, lack of institutional protocols and centralized information). Participants noted that greater socialization and connection to existing educational resources regarding the intended purpose, scope, and applicability of advance directives could benefit home care patients.

SSR1 and CKAP4 as potential biomarkers for intervertebral disc degeneration based on integrated bioinformatics analysis.

Background: Intervertebral disc degeneration (IDD) is a significant cause of low back pain and poses a significant public health concern. Genetic factors play a crucial role in IDD, highlighting the need for a better understanding of the underlying mechanisms. Aim: The aim of this study was to identify potential IDD-related biomarkers using a comprehensive bioinformatics approach and validate them in vitro. Materials and Methods: In this study, we employed several analytical approaches to identify the key genes involved in IDD. We utilized weighted gene coexpression network analysis (WGCNA), MCODE, LASSO algorithms, and ROC curves to identify the key genes. Additionally, immune infiltrating analysis and a single-cell sequencing dataset were utilized to further explore the characteristics of the key genes. Finally, we conducted in vitro experiments on human disc tissues to validate the significance of these key genes in IDD. Results: we obtained gene expression profiles from the GEO database (GSE23130 and GSE15227) and identified 1015 DEGs associated with IDD. Using WGCNA, we identified the blue module as significantly related to IDD. Among the DEGs, we identified 47 hub genes that overlapped with the genes in the blue module, based on criteria of |logFC| ≥ 2.0 and p.adj <0.05. Further analysis using both MCODE and LASSO algorithms enabled us to identify five key genes, of which CKAP4 and SSR1 were validated by GSE70362, demonstrating significant diagnostic value for IDD. Additionally, immune infiltrating analysis revealed that monocytes were significantly correlated with the two key genes. We also analyzed a single-cell sequencing dataset, GSE199866, which showed that both CKAP4 and SSR1 were highly expressed in fibrocartilage chondrocytes. Finally, we validated our findings in vitro by performing real time polymerase chain reaction (RT-PCR) and immunohistochemistry (IHC) on 30 human disc samples. Our results showed that CKAP4 and SSR1 were upregulated in degenerated disc samples. Taken together, our findings suggest that CKAP4 and SSR1 have the potential to serve as disease biomarkers for IDD.

Gossypol Acetic Acid alleviates the Ferroptosis of Chondrocytes in Osteoarthritis by Inhibiting GPX4 Methylation.

BACKGROUND: Osteoarthritis (OA) is a chronic joint disease, usually accompanied by degeneration of the articular cartilage, fibrosis, bone hyperplasia around the joint, and damage to the entire articular surface. Gossypol is a natural phenolic compound isolated from the seed of cotton plants, and gossypol acetic acid (GAA) is a medicinal form of Gossypol. Recently, various biological activities of GAA, including anti-inflammatory and anti-tumor effects, have been widely reported. However, its effect on chondrocytes in OA has yet to be determined. METHODS: In this study, we investigated the effect of GAA on ferroptosis in OA chondrocytes. The effect of GAA on the cell viability and cytotoxicity of chondrocytes in rat cells was investigated using CCK8. Western blotting, Reverse-transcription PCR (RT-PCR), and immunofluorescence staining were used to elucidate the molecular mechanisms and signaling pathways of GAA inhibition of ferroptosis in OA chondrocytes. The effect of GAA on reactive oxygen species (ROS) production and lipid peroxidation levels in chondrocytes was examined using dihydroethidium (DHE) staining and fluorescent dye BODIPY581/591 C11. in vivo, micro-CT imaging, hematoxylin and eosin staining, Safranin O-Fast staining, and immunohistochemistry were performed to evaluate the effects of GAA on OA cartilage. RESULTS: The results showed that GAA treatment regulated the expression of chondrocyte extracellular matrix (ECM) related factors, including ADAMTS5, MMP13, SOX9, Aggrecan, and COL1A2 and reduced the ROS and lipid peroxidation levels. Besides, Erastin could reverse the effects of GAA on chondrocytes. Similar to GAA, 5-AZA caused the reduction of ROS and lipid peroxidation levels and reversed the effect of IL-1ß on the expression of ECM-related factors in OA chondrocytes. The above results clarified that GAA alleviated the ferroptosis of chondrocytes in OA by inhibiting GPX4 methylation. CONCLUSION: Our findings revealed that GAA might be developed as a drug for treating OA clinically.

Decoding the mitochondrial connection: development and validation of biomarkers for classifying and treating systemic lupus erythematosus through bioinformatics and machine learning.

BACKGROUND: Systemic lupus erythematosus (SLE) is a multifaceted autoimmune disease characterized by clinical and pathological diversity. Mitochondrial dysfunction has been identified as a critical pathogenetic factor in SLE. However, the specific molecular aspects and regulatory roles of this dysfunction in SLE are not fully understood. Our study aims to explore the molecular characteristics of mitochondria-related genes (MRGs) in SLE, with a focus on identifying reliable biomarkers for classification and therapeutic purposes. METHODS: We sourced six SLE-related microarray datasets (GSE61635, GSE50772, GSE30153, GSE99967, GSE81622, and GSE49454) from the Gene Expression Omnibus (GEO) database. Three of these datasets (GSE61635, GSE50772, GSE30153) were integrated into a training set for differential analysis. The intersection of differentially expressed genes with MRGs yielded a set of differentially expressed MRGs (DE-MRGs). We employed machine learning algorithms-random forest (RF), support vector machine (SVM), and least absolute shrinkage and selection operator (LASSO) logistic regression-to select key hub genes. These genes' classifying potential was validated in the training set and three other validation sets (GSE99967, GSE81622, and GSE49454). Further analyses included differential expression, co-expression, protein-protein interaction (PPI), gene set enrichment analysis (GSEA), and immune infiltration, centered on these hub genes. We also constructed TF-mRNA, miRNA-mRNA, and drug-target networks based on these hub genes using the ChEA3, miRcode, and PubChem databases. RESULTS: Our investigation identified 761 differentially expressed genes (DEGs), mainly related to viral infection, inflammatory, and immune-related signaling pathways. The interaction between these DEGs and MRGs led to the identification of 27 distinct DE-MRGs. Key among these were FAM210B, MSRB2, LYRM7, IFI27, and SCO2, designated as hub genes through machine learning analysis. Their significant role in SLE classification was confirmed in both the training and validation sets. Additional analyses included differential expression, co-expression, PPI, GSEA, immune infiltration, and the construction of TF-mRNA, miRNA-mRNA, and drug-target networks. CONCLUSIONS: This research represents a novel exploration into the MRGs of SLE, identifying FAM210B, MSRB2, LYRM7, IFI27, and SCO2 as significant candidates for classifying and therapeutic targeting.

Health Information Technology Adoption at U.S. Home Health Care Agencies: Results from a Multi-Methods Study.

Health information technology (HIT) holds potential to transform Home Health Care (HHC), yet, little is known about its adoption in this setting. In the context of infection prevention and control, we aimed to: (1) describe challenges associated with the adoption of HIT, for example, electronic health records (EHR) and telehealth and (2) examine HHC agency characteristics associated with HIT adoption. We conducted in-depth interviews with 41 staff from 13 U.S. HHC agencies (May-October 2018), then surveyed a stratified random sample of 1506 agencies (November 2018-December 2019), of which 35.6% participated (N = 536 HHC agencies). We applied analytic weights, generating nationally-representative estimates, and computed descriptive statistics, bivariate and multivariable analyses. Four themes were identified: (1) Reflections on providing HHC without EHR; (2) Benefits of EHR; (3) Benefits of other HIT; (4) Challenges with HIT and EHR. Overall, 10% of the agencies did not have an EHR; an additional 2% were in the process of acquiring one. Sixteen percent offered telehealth, and another 4% were in the process of acquiring telehealth services. In multivariable analysis, EHR use varied significantly by geographic location and ownership, and telehealth use varied by geographic location, ownership, and size. Although HIT use has increased, our results indicate that many HHC agencies still lack the HIT needed to implement technological solutions to improve workflow and quality of care. Future research should examine the impact of HIT on patient outcomes and the impact of the COVID-19 pandemic on HIT use in HHC.

Development of a nutritional screening and assessment indicator system for patients with esophageal cancer in China: Findings from the Delphi method.

BACKGROUND: In China, individuals diagnosed with esophageal cancer are confronted with an elevated risk of nutritional inadequacy or malnutrition throughout the course of their disease, a condition that contributes to various adverse clinical outcomes. A vast corpus of data are burgeoning at an unprecedented rate, primarily due to the revolutionary growth of digitalization technologies and artificial intelligence, notably within the domains of health care and medicine. The purpose of this investigation is to initiate the development of a nutritional screening and assessment indicator framework for patients with esophageal cancer within the Chinese context. We seek to furnish an instrumental reference to facilitate preparations for the forthcoming era of advanced, "deep," evidence-based medicine. METHODS: An integrative methodology was employed to forge the preliminary draft of the nutritional screening and assessment indicator system for preoperative patients with esophageal cancer. This encompassed a rigorous literature survey, in-depth clinical practice investigation, and the facilitation of expert panel discussions. Thereafter, two iterative consultation phases were conducted using the Delphi method in China. The analytic hierarchy process was deployed to ascertain the weighting of each index within the definitive evaluation indicator system. RESULTS: The effective response rates for the dual rounds of expert consultation were 91.7% and 86.4%, with commensurate authority coefficients of 0.97 and 0.91. The Kendall harmony coefficients were ascertained to be 0.19 and 0.14 (p < 0.01), respectively. The culminating nutritional screening and assessment indicator system for patients with esophageal cancer comprised 5 primary-level indicators and 38 secondary-level indicators. CONCLUSIONS: The nutritional screening and assessment indicator system contrived for patients with esophageal cancer is underpinned by cogent theoretical principles, leverages an astute research methodology, and manifests dependable outcomes. This system may be appositely utilized as a meaningful reference for the nutritional screening and assessment process in patients afflicted with esophageal cancer.

Nursing care of patients with relapsed and refractory multiple myeloma treated with B-cell mature antigen-targeted universal chimeric antigen receptor T cells.

To investigate the efficacy of a nursing approach using B-cell maturation antigen (BCMA)-targeted universal chimeric antigen receptor T-cell (BCMA-UCART) immunotherapy in the treatment of 8 patients with relapsed refractory multiple myeloma (MM). In this study, 16 patients with relapsed and refractory MM who were treated with BCMA-targeted UCART in our department from May 2020 to November 2022 were selected, and were divided into a control group and an experimental group of 8 cases each according to the difference in the nursing methods, and the control group adopted the conventional universal nursing program. The experimental group used the nursing protocol that cooperated with the immunotherapy of this study, and the main points of nursing care included timely assessment of organ functional status, safe and accurate infusion of BCMA-UCART, identification and management of hyperthermia, hypotension, arrhythmia and central nervous system adverse reactions caused by cytokine release after BCMA-UCART infusion, as well as management of fluid imbalance, maintenance of stable blood pressure, and cooperation with physicians to effectively control of inflammatory factors. In addition, patients were provided with psychological and dietary support. The duration of hospitalization was compared between the two groups after the intervention. The discharge time of the experimental group was significantly shorter than that of the control group (P he.05), and the experimental group effectively controlled cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome and acute graft-versus-host disease. The nursing program with BCMA-UCART immunotherapy is effective in intervening MM patients and promotes their early recovery and discharge from the hospital.

Busulfan/Cyclophosphamide Compared with Melphalan as a Conditioning Regimen for Autologous Transplantation of Multiple Myeloma: A Long-Term Assessment.

BACKGROUND: Melphalan was poorly available in mainland China. The aim of this study is to explore the dose-adjusted busulfan/cyclophosphamide (BU/CY) as an alternative regimen in auto stem cell transplantation (ASCT) for multiple myeloma (MM). METHODS: A total of 105 newly diagnosed MM patients undergoing ASCT during May 2012 and August 2017 were retrospectively analyzed. The BU/CY regimen was applied to 64 patients. Busulfan (9.6 mg/kg or 8.0 mg/kg in total) and cyclophosphamide (3.6 g/m2 or 3.0 g/m2 in total) were administered according to the creatinine clearance rate (CCR). A high-dose melphalan (HDMEL) regimen (200 mg/m2) was given to the other 41 patients. RESULTS: At a median follow-up of 65 (1~119) months, estimated overall survival (OS) and progression-free survival (PFS) at 104 months in the BU/CY and HDMEL groups were 35.6% vs. 20.5% (p = 0.263) and 20.2% vs. 2.4% (p = 0.035), respectively. The median overall survival (OS) and PFS of the HDMEL and BU/CY groups were 55 vs. 70.5 months and 26 vs. 46.5 months, respectively. In multivariate analysis, the BU/CY regimen was found to be the only protective factor for PFS. No lethal toxicity was found in the BU/CY group, and treatment-related mortality (TRM) in 100 days was similar to the HDMEL group. CONCLUSIONS: MM patients may also benefit from the dose-adjusted BU/CY regimen.

CK1ε drives osteogenic differentiation of bone marrow mesenchymal stem cells via activating Wnt/ß-catenin pathway.

The treatment of bone defects is a difficult problem in orthopedics. At present, the treatment mainly relies on autologous or allogeneic bone transplantation, which may lead to some complications such as foreign body rejection, local infection, pain, or numbness at the bone donor site. Local injection of conservative therapy to treat bone defects is one of the research hotspots at present. Bone marrow mesenchymal stem cells (BMSCs) can self-renew, significantly proliferate, and differentiate into various types of cells. Although it has been reported that CK1ε could mediate the Wnt/ß-catenin pathway, leading to the development of the diseases, whether CK1ε plays a role in bone regeneration through the Wnt/ß-catenin pathway has rarely been reported. The purpose of this study was to investigate whether CK1ε was involved in the osteogenic differentiation (OD) of BMSCs through the Wnt/ß-catenin pathway and explore the mechanism. We used quantitative reverse transcription-polymerase chain reaction (qRT-qPCR), Western blots, immunofluorescence, alkaline phosphatase, and alizarin red staining to detect the effect of CK1ε on the OD of BMSCs and the Wnt/ß-catenin signaling pathway. CK1ε was highly expressed in BMSCs with OD, and our study further demonstrated that CK1ε might promote the OD of BMSCs by activating DLV2 phosphorylation, initiating Wnt signaling downstream, and activating ß-catenin nuclear transfer. In addition, by locally injecting a CK1ε-carrying adeno-associated virus (AAV5- CK1ε) into a femoral condyle defect rat model, the overexpression of CK1ε significantly promoted bone repair. Our data show that CK1ε was involved in the regulation of OD by mediating Wnt/ß-catenin. This may provide a new strategy for the treatment of bone defects.
