Economic Burden, Length of Hospital Stay and Complication of Simultaneous versus Staged Bilateral Hip Arthroplasty: A Hospital Prospective Study.

Background: Bilateral hip arthroplasty is a common surgical intervention for patients with bilateral hip disease. The decision between simultaneous versus staged procedures remains debated, primarily due to concerns over cost, postoperative recovery, and complication rates. This study aimed to evaluate the economic burden and clinical outcomes of simultaneous versus staged bilateral hip arthroplasty. Methods: In this single-center, prospective study, patients who underwent bilateral hip replacement at XXX between 2021 and 2022 were included. Participants were divided into groups based on the surgical approach: simultaneous bilateral hip arthroplasty or staged bilateral hip arthroplasty. Data on costs, operation times, hospital stay lengths, and postoperative outcomes were collected and analyzed. Results: A total of 57 patients were studied, with 45 undergoing simultaneous and 12 staged surgeries. The total cost for staged procedures was significantly higher, with a mean difference of 63,967.54 yuan compared to simultaneous procedures. No significant difference was found in prosthesis costs between the groups. Operation times and hospital stays did not significantly differ, with averages closely aligned between the simultaneous (operation time: 3.2 hours, hospital stay: 5 days) and staged groups (operation time: 3.4 hours, hospital stay: 5.2 days). The obesity rate was higher in the simultaneous group (P < 0.05). Conclusion: Simultaneous bilateral hip arthroplasty appears to be an economically favorable option, with comparable perioperative and immediate postoperative outcomes to staged procedures. These insights have significant implications for clinical practice and policy-making, suggesting that simultaneous procedures can be safely implemented for appropriate patients, potentially optimizing healthcare resources.

Association of Methyl Donor Nutrients' Dietary Intake and Cognitive Impairment in the Elderly Based on the Intestinal Microbiome.

Globally, cognitive impairment (CI) is the leading cause of disability and dependency among the elderly, presenting a significant public health concern. However, there is currently a deficiency in pharmacological interventions that can effectively cure or significantly reverse the progression of cognitive impairment. Methyl donor nutrients (MDNs), including folic acid, choline, and vitamin B12, have been identified as potential enhancers of cognitive function. Nevertheless, there remains a dearth of comprehensive research investigating the connection between the dietary intake of MDNs and CI. In our study, we comprehensively assessed the relationship between MDNs' dietary intake and CI in older adults, utilizing 16S rRNA gene sequencing to investigate the potential underlying mechanisms. The results showed an obvious difference in the methyl-donor nutritional quality index (MNQI) between the dementia (D) group and the dementia-free (DF) group. Specifically, there was a lower MNQI in the D group than that in the DF group. For the gut microbiome, the beta diversity of gut flora exhibited higher levels in the high methyl-donor nutritional quality (HQ) group as opposed to the low methyl-donor nutritional quality (LQ) group, and lower levels in the D group in comparison to the DF group. Subsequently, we performed a correlation analysis to examine the relationship between the relative abundance of microbiota, the intake of MDNs, and Montreal Cognitive Assessment (MoCA) scores, ultimately identifying ten genera with potential regulatory functions. Additionally, KEGG pathway analyses suggested that the one-carbon metabolism, chronic inflammation, and DNA synthesis potentially serve as pathways through which MDNs may be promising for influencing cognitive function. These results implied that MDNs might have the potential to enhance cognitive function through the regulation of microbiota homeostasis. This study offers dietary recommendations for the prevention and management of CI in the elderly.

Association of methyl donor nutrients dietary intake and sleep disorders in the elderly revealed by the intestinal microbiome.

Currently, sleep disorders (SD) in the elderly are gaining prominence globally and are becoming a significant public health concern. Methyl donor nutrients (MDNs), such as vitamin B6, vitamin B12, folate, and choline, have been reported to have the potential to improve sleep disorders. Moreover, MDNs help to maintain gut flora homeostasis, and are closely associated with the development of SD. Nevertheless, there has been a lack of comprehensive human studies examining the association between MDNs intake and SD. In our study, we comprehensively evaluated the association between MDNs intake and SD in the elderly and used 16S rRNA gene sequencing to explore the underlying mechanism. We found that the SD group (n = 91) had a lower methyl-donor nutritional quality index (MNQI) and a trend toward lower intake compared to the control group (n = 147). Based on the intestinal microbiome, the beta diversity of the intestinal flora was higher in the high methyl-donor nutritional quality (HQ) group compared to the low methyl-donor nutritional quality (LQ) group, and it was lower in the SD group compared to the control group. This suggests that MDNs may regulate sleep by modulating the abundance distribution of the microbiota. Subsequently, we performed correlation analyses between the relative abundance of the microbiota, MDNs intake, and the Pittsburgh Sleep Quality Index (PSQI), identifying five genera with potential regulatory roles. The KEGG pathway analysis indicated that energy metabolism and one-carbon metabolism might be the pathways through which MDNs modulate sleep. This study offers dietary guidance strategies for managing SD in the elderly and provides insights for targeted microbiota intervention.

Self-Assembled Multilayer-Modified Needles Simulate Acupuncture and Diclofenac Sodium Delivery for Rheumatoid Arthritis.

A novel therapeutic approach combining acupuncture and diclofenac sodium (DS) administration was established for the potential treatment for rheumatoid arthritis (RA). DS is a commonly used anti-inflammatory and analgesic drug but has short duration and adverse effects. Acupoints are critical linkages in the meridian system and are potential candidates for drug delivery. Herein, we fabricated a DS-loaded multilayer-modified acupuncture needle (DS-MMAN) and investigated its capacity for inhibiting RA. This DS-MMAN possesses sustained release properties and in vitro anti-inflammatory effects. Experimental results showed that the DS-MMAN with microdoses can enhance analgesia and efficiently relieve joint swelling compared to the oral or intra-articular administration of DS with gram-level doses. Moreover, the combination of acupoint and DS exerts a synergistic improvement in inflammation and joint damage. Cytokine and T cell analyses in the serum indicated that the application of DS-MMAN suppressed the levels of pro-inflammatory factors and increased the levels of anti-inflammatory factors. Furthermore, the acupoint administration via DS-MMAN could decrease the accumulation of DS in the liver and kidneys, which may express better therapeutic efficiency and low toxicity. The present study demonstrated that the acupuncture needle has the potential to build a bridge between acupuncture and medication, which would be a promising alternative to the combination of traditional and modern medicine.

Exogenous Nucleotides Ameliorate Insulin Resistance Induced by Palmitic Acid in HepG2 Cells through the IRS-1/AKT/FOXO1 Pathways.

Nucleotides (NTs) act as pivotal regulatory factors in numerous biological processes, playing indispensable roles in growth, development, and metabolism across organisms. This study delves into the effects of exogenous NTs on hepatic insulin resistance using palmitic-acid-induced HepG2 cells, administering interventions at three distinct dosage levels of exogenous NTs. The findings underscore that exogenous NT intervention augments glucose consumption in HepG2 cells, modulates the expression of glycogen-synthesis-related enzymes (glycogen synthase kinase 3ß and glycogen synthase), and influences glycogen content. Additionally, it governs the expression levels of hepatic enzymes (hexokinase, phosphoenolpyruvate carboxykinase, and glucose-6-phosphatase). Moreover, exogenous NT intervention orchestrates insulin signaling pathway (insulin receptor substrate-1, protein kinase B, and forkhead box protein O1) and AMP-activated protein kinase (AMPK) activity in HepG2 cells. Furthermore, exogenous NT intervention fine-tunes the expression levels of oxidative stress-related markers (malondialdehyde, glutathione peroxidase, and NADPH oxidase 4) and the expression of inflammation-related nuclear transcription factor (NF-κB). Lastly, exogenous NT intervention regulates the expression levels of glucose transporter proteins (GLUTs). Consequently, exogenous NTs ameliorate insulin resistance in HepG2 cells by modulating the IRS-1/AKT/FOXO1 pathways and regulate glucose consumption, glycogen content, insulin signaling pathways, AMPK activity, oxidative stress, and inflammatory status.

Targeting Aging and Longevity with Exogenous Nucleotides (TALENTs): Rationale, Design, and Baseline Characteristics from a Randomized Controlled Trial in Older Adults.

Nucleotides (NTs), important biomolecules involved in numerous cellular processes, have been proposed as potential candidates for anti-aging interventions. However, whether nucleotides can act as an anti-aging supplement in older adults remains unclear. TALENTs is a randomized, double-blinded, placebo-controlled trial that evaluates the efficacy and safety of NTs as an anti-aging supplement in older adults by exploring the effects of NTs on multiple dimensions of aging in a rigorous scientific setting. Eligible community-dwelling adults aged 60-70 years were randomly assigned equally to two groups: nucleotides intervention group and placebo control group. Comprehensive geriatric health assessments were performed at baseline, 2-months, and 4-months of the intervention. Biological specimens were collected and stored for age-related biomarker testing and multi-omics sequencing. The primary outcome was the change from baseline to 4 months on leukocyte telomere length and DNA methylation age. The secondary aims were the changes in possible mechanisms underlying aging processes (immunity, inflammatory profile, oxidative stress, gene stability, endocrine, metabolism, and cardiovascular function). Other outcomes were changes in physical function, body composition and geriatric health assessment (including sleep quality, cognitive function, fatigue, frailty, and psychology). In the RCT, 301 participants were assessed for eligibility and 122 were enrolled. Participants averaged 65.65 years of age, and were predominately female (67.21%). All baseline characteristics were well-balanced between groups, as expected due to randomization. The majority of participants were pre-frailty and had at least one chronic condition. The mean scores for physical activity, psychological, fatigue and quality of life were within the normal range. However, nearly half of the participants still had room for improvement in cognitive level and sleep quality. This TALENTs trial will represent one of the most comprehensive experimental clinical trials in which supplements are administered to elderly participants. The findings of this study will contribute to our understanding of the anti-aging effects of NTs and provide insights into their potential applications in geriatric healthcare.

Treatment of malignant airway obstruction with Y-shape sigma stent loaded with I125 seeds installed via rigid bronchoscopy.

PURPOSE: To summarize and analyze the safety and efficacy of a Y-shape Sigma stent loaded with I125 in patients with inoperable malignant main airway obstruction. METHODS: This study was approved by the Institutional Ethics Committee, and a written informed consent was obtained from each participant. A Y-shape Sigma stent loaded with I125 was placed under vision from rigid bronchoscopy. The primary endpoint was alleviation of symptoms and improvement of Karnofsky Performance Status (KPS) score, and the secondary endpoint was complications and technical success. RESULTS: From November 2018 through June 2023, total 33 patients with malignant airway obstruction were palliatively treated by installing Y-shape Sigma stents loaded with I125. The airway lumen was immediately restored and the average airway opening significantly increased to 70 ± 9.4% after the procedure from baseline 30.2 ± 10.5% (p < 0.05). Average KPS score was improved from baseline 30.0 ± 10.0 to 70.0 ± 10.0 (p < 0.05) as well as PaO2 from baseline 50.1 ± 15.4 mmHg to 89.3 ± 8.6 mmHg (p < 0.05). The technical success rate of placing the stent in this study was 73%, and adverse events or complications including bleeding, I125 loss, and airway infection occurred during or after the procedure. CONCLUSION: Placement of Y-shape Sigma stents under vision from rigid bronchoscopy in the patients with malignant airway obstruction is feasible and it immediately alleviates dyspnea and significantly improves quality of life.

The Validity and Feasibility of Utilizing the Photo-Assisted Dietary Intake Assessment among College Students and Elderly Individuals in China.

Dietary assessments hold significant importance within the field of public health. However, the current methods employed for dietary assessments face certain limitations and challenges that necessitate improvement. The aim of our study was to develop a reliable and practical dietary assessment tool known as photo-assisted dietary intake assessment (PAD). In order to evaluate its validity, we conducted an analysis on a sample of 71 college students' dinners at a buffet in a canteen. We compared estimates of food weights obtained through the 24-h recall (24 HR) or PAD method with those obtained through the weighing method; we also evaluated the feasibility of PAD for recording dinner intakes among a sample of college students (n = 76) and elderly individuals (n = 121). In addition, we successfully identified the dietary factors that have a significant impact on the bias observed in weight estimation. The findings of the study indicated that the PAD method exhibited a higher level of consistency with the weighing method compared to the 24 HR method. The discrepancy in D% values between cereals (14.28% vs. 40.59%, P < 0.05), vegetables (17.67% vs. 44.44%, P < 0.05), and meats (14.29% vs. 33.33%, P < 0.05) was clearly apparent. Moreover, a significant proportion of the food mass value acquired through the PAD method fell within the limits of agreement (LOAs), in closer proximity to the central horizontal line. Furthermore, vegetables, cereals, eggs, and meats, for which the primary importance lies in accuracy, exhibited a considerably higher bias with the 24 HR method compared to the PAD method (P < 0.05), implying that the PAD method has the potential to mitigate the quality bias associated with these food items in the 24 HR method. Additionally, the PAD method was well received and easily implemented by the college students and elderly individuals. In conclusion, the PAD method demonstrates a considerable level of accuracy and feasibility as a dietary assessment method that can be effectively employed across diverse populations.

Perioperative safety assessment of patients undergoing unilateral or bilateral hip replacements.

Introduction: Due to the aging of the world population and the increase of obesity rate, it is expected that the number of joint replacement surgery will continue to increase in the next few years. This study evaluated the safety differences between unilateral and bilateral hip replacement surgeries. Methods: The data for patients who underwent hip arthroplasty in 2021 and 2022 were examined. The data set included 68 patients who were grouped according to the type of hip replacement needed, sex, age, and body mass index. Total blood loss and operative time were the safety-related indicators used to compare the groups. Results: Regardless of whether the unilateral replacement group was compared with the overall bilateral replacement group or separately with the staged and simultaneous bilateral replacement groups, simultaneous bilateral replacement surgeries were equally safe as the other types of hip replacements. The total blood loss and operative time for the simultaneous bilateral replacement group were not significantly different from those in the unilateral and staged bilateral replacement groups. For overweight patients, the operative time for simultaneous bilateral replacements was significantly shorter than that for unilateral replacements. Conclusions: These findings suggest that for patients requiring bilateral hip replacements, the blood loss risk for patients undergoing simultaneous bilateral hip replacements was similar to that for patients undergoing either unilateral or staged bilateral hip replacements. Thus, simultaneous bilateral total hip replacement (THR) are safe and should be considered for candidate patients.

Design of an Injectable Magnetic Hydrogel Based on the Tumor Microenvironment for Multimodal Synergistic Cancer Therapy.

Conventional tumor chemotherapy is limited by its low therapeutic efficacy and side effects, which severely hold back its further application. Drug delivery systems (DDSs) based on nanomaterials have attracted wide interest in cancer treatment; especially, the system can realize efficient synergistic therapies. Here, we designed a smart hydrogel drug delivery system with multiple responses to enhance the tumor treatment effect. By cross-linking oxidized hydroxypropyl cellulose with carboxymethyl chitosan, an injectable hydrogel was obtained, into which artesunate (ART), ferroferric oxide (Fe3O4) nanoparticles, and black phosphorus nanosheets (BPs) were preloaded. This DDS has multiple functions including magnetic targeting, pH sensitivity, chemodynamic therapy, and photothermal response. This nanoparticle-composited hydrogel not only preserved excellent rheological properties but also allowed for an accurate stable drug release at tumor sites and synergistic effects of multiple therapies. The in vitro and in vivo experiments revealed that this DDS could efficiently eliminate the HepG2 tumor with good biocompatibility. Taken together, this study clarifies the possible antitumor mechanism of this ART-loaded nanoparticle-composited hydrogel and provides a new strategy for synergistic photothermal-chemo-chemodynamic therapy.

Chinese medicine Fufang Zhenzhu Tiaozhi capsule ameliorates coronary atherosclerosis in diabetes mellitus-related coronary heart disease minipigs.

BACKGROUND: Diabetes mellitus-related coronary heart disease (DM-CHD) is the most common cause of death in diabetic patients. Various studies have shown that Chinese medicine Fufang-Zhenzhu-Tiaozhi capsule (FTZ) has therapeutic effects on cardiovascular diseases. More research is required to determine the mechanism of FTZ protection against coronary atherosclerosis. OBJECTIVE: To investigate the unique mechanism of FTZ in treatment of DM-CHD minipigs with coronary atherosclerosis. METHODS: High-fat/high-sucrose/high-cholesterol diet combined with streptozotocin and coronary balloon injury were used to induce DM-CHD minipig model, which was then randomly divided into: DM-CHD model, DM-CHD treated with FTZ or positive drug (Metformin + Atorvastatin, M+A). After twenty-two weeks, ultrasonography, electrocardiography, and image detection were employed to detect cardiac functions and assess coronary artery stenosis and plaque. Human umbilical vein endothelial cells (HUVECs) were treated high glucose or/and FTZ. Pigs tissues and treated-cells were collected for further testing. RESULTS: In DM-CHD minipigs, FTZ treatment significantly reduced disordered glycolipid metabolism similar as M+A administration. FTZ and M+A also alleviated coronary stenosis and myocardial injury. In addition, IκB and NF-κB phosphorylation levels, as well as the protein levels of IL-1ß, Bax, cleave-Caspase 3, Bcl-2, and α-SMA were dramatically increased in the DM-CHD coronary artery, whereas CD31 and VE-cadherin expressions were decreased. Similar to M+A, FTZ reversed these protein levels in the DM-CHD coronary artery. Furthermore, FTZ ameliorated the damage and high migration activity of HUVECs induced by high glucose. CONCLUSIONS: FTZ improves coronary atherosclerosis through modulating inflammation, alleviating apoptosis, and inhibiting EndMT of coronary artery to protects against DM-CHD.

Biochar combined with organic and inorganic fertilizers promoted the rapeseed nutrient uptake and improved the purple soil quality.

Biochar is a kind of organic matter that can be added into soil to improve soil quality. To study the effect of biochar combined with organic and inorganic fertilizers on rapeseed growth and purple soil fertility and microbial community, a completely randomized block design was designed with three levels of biochar (B0: no biochar, B1: low-rate biochar, B2: high-rate biochar); two levels of inorganic fertilizers (F1: low-rate inorganic fertilizer; F2: high-rate inorganic fertilizer); and two levels of organic fertilizers (M1: no organic fertilizer; M2: with organic fertilizer). All combinations were repeated three times. The combined application of biochar and organic and inorganic fertilizers could improve soil pH, soil fertility and soil microbial community richness: The pH of B1F2M1 increased 0.41 compared with the control, the nitrogen, phosphorus and potassium content increased by 103.95, 117.88, and 99.05%. Meanwhile, soil microbial community richness was also improved. Our research showed that biochar could promote the Nutrient Uptake of rapeseed, and the combined application of biochar with organic and inorganic fertilizers could improve soil fertility and increase microbial diversity. Low-rate biochar combined with organic fertilizer and low-rate inorganic fertilizer was the most suitable application mode in rapeseed production in purple soil area of Southwest China.

Short-term Effectiveness of a Modified Osteotomy for Total Elbow Joint Replacement in Patients of Hemophilic Elbow Arthritis with Severe Flexion Contracture Deformity: A Three-Cases Series Report.

OBJECTIVE: To report the modified osteotomy and the short-term effectiveness of the total elbow joint replacement in patients of hemophilic elbow arthritis with severe flexion contracture deformity. METHODS: This study introduced the therapeutic approach of the total elbow joint replacement in patients of hemophilic elbow arthritis with severe flexion contracture deformity, and assessed the short-term effectiveness in three cases (three elbows) of end-stage hemophilic elbow arthritis admitted from October 2020 to December 2020. The included patients were all diagnosed with hemophilia A (factor VII deficiency), accompanied by severe bilateral elbow joint flexion contracture, which seriously affects daily life and requires surgical intervention. Clinical data and follow-up results were analyzed before total elbow arthroplasty and 1, 3, and 6 months postoperatively. Pre- and postoperative range of motion, pain score, and function score were compared, and intraoperative and postoperative complications are reported. RESULTS: All three patients were male, with an average age of 31 years. The main clinical manifestations were bilateral elbow arthritis with flexion contracture. Two of the patients underwent right elbow replacement, and one patient underwent left elbow replacement. All cases were followed up for 6 months postoperatively. No incision infection or ulnar nerve injury occurred. Postoperative triceps brachii muscle strength was slightly weakened compared with preoperative muscle strength. Average elbow flexion and extension range of motion was 60° (30°-100°) preoperatively and increased to 127° (110°-140°) postoperatively; rotational range of motion of the affected forearm was 47° (10°-85°) preoperatively and increased to 117° postoperatively. The mean visual analogue scale (VAS) was 6 (5-8) preoperatively and decreased to 3 (2-4) postoperatively. The mean MEPS score was 62 (55-75) and increased to 87 (80-95) postoperatively. During the follow-up, anteroposterior and lateral radiographs showed no signs of prosthesis loosening in the elbow. CONCLUSIONS: For severe hemophilic elbow arthritis patients, the short-term treatment effect of total elbow replacement is good, following the strict adherence to the surgical indications and proper preparation for the perioperative period. The modified osteotomy can fully expose the visual field and reduce complications of ulnar nerve injury. The long-term effects need to be study future.

Traditional Chinese Medicine Fufang-Zhenzhu-Tiaozhi capsule prevents renal injury in diabetic minipigs with coronary heart disease.

BACKGROUND: Renal injury is one of the common microvascular complications of diabetes, known as diabetic kidney disease (DKD) seriously threatening human health. Previous research has reported that the Chinese Medicine Fufang-Zhenzhu-Tiaozhi (FTZ) capsule protected myocardia from injury in diabetic minipigs with coronary heart disease (DM-CHD). And we found significant renal injury in the minipigs. Therefore, we further investigated whether FTZ prevents renal injury of DM-CHD minipig and H2O2-induced oxidative injury of HK-2 cells. METHODS: DM-CHD model was established by streptozotocin injection, high fat/high-sucrose/high-cholesterol diet combined with balloon injury in the coronary artery. Blood lipid profile, fasting blood glucose (FBG), and SOD were measured with kits. The levels of blood urea nitrogen (BUN), serum creatinine (Scr), urine trace albumin (UALB), urine creatinine (UCR) (calculate UACR), cystatin (Cys-C), and ß-microglobulin (ß-MG) were measured by ELISA kits to evaluate renal function. TUNEL assay was performed to observe the apoptosis. qPCR was used to detect the mRNA expression levels of HO-1, NQO1, and SOD in kidney tissue. The protein expressions of Nrf2, HO-1, NQO1, Bax, Bcl-2, and Caspase 3 in the kidney tissue and HK-2 cells were detected by western blot. Meanwhile, HK-2 cells were induced by H2O2 to establish an oxidative stress injury model to verify the protective effect and mechanisms of FTZ. RESULTS: In DM-CHD minipigs, blood lipid profile and FBG were elevated significantly, and the renal function was decreased with the increase of BUN, Scr, UACR, Cys-c, and ß-MG. A large number of inflammatory and apoptotic cells in the kidney were observed accompanied with lower levels of SOD, Bcl-2, Nrf2, HO-1, and NQO1, but high levels of Bax and Cleaved-caspase 3. FTZ alleviated glucose-lipid metabolic disorders and the pathological morphology of the kidney. The renal function was improved and the apoptotic cells were reduced by FTZ administration. FTZ could also enhance the levels of SOD, Nrf2, HO-1, and NQO1 proteins to promote antioxidant effect, down-regulate the expression of Bax and Caspase3, as well as up-regulate the expression of Bcl-2 to inhibit cell apoptosis in the kidney tissue and HK-2 cells. CONCLUSIONS: We concluded that FTZ prevents renal injury of DM-CHD through activating anti-oxidative capacity to reduce apoptosis and inhibiting inflammation, which may be a new candidate for DKD treatment.

Perioperative blood loss during joint replacement: comparison between patients with and without hemophilia.

BACKGROUND: Although arthroplasty provides satisfactory pain relief, functional improvement, and reduced flexion contracture in patients with hemophilia arthropathy, bleeding remains the primary problem associated with hemophilic arthropathy joint replacement. We aimed to explore the differences in perioperative blood loss (PBL) associated with joint replacement surgery in patients with and without hemophilia. METHODS: This study retrospectively analyzed 61 cases of PBL in patients undergoing joint replacement surgery, including 37 patients with hemophilia and 24 patients without hemophilia. All patients demonstrated severe joint flexion contractures that seriously affected their daily lives and required surgical intervention. PBL was compared between the two groups. RESULTS: In univariate analysis, the overall (p < 0.001) and hidden (p < 0.001) blood losses were significantly higher for patients with hemophilia than those for patients without hemophilia. However, after adjustment for multiple factors, there was no significant difference in overall blood loss between the two groups (p = 0.731). In addition, sex, age group, and surgical site did not affect blood loss in patients with hemophilia. CONCLUSION: Overt bleeding did not increase significantly in patients with hemophilia, compared with that in patients without hemophilia. In terms of blood loss, joint replacement surgery for patients with hemophilia is relatively safe. The results of this study must be verified by a prospective follow-up study with larger sample size. Trial registration Retrospectively registered.

Human epididymis protein 4: a novel predictor of ischemic cardiomyopathy.

BACKGROUND: The prognostic value of human epididymis protein 4 (HE4) in patients with ischemic cardiomyopathy (ICM) is unknown. METHODS: A total of 103 patients with ICM were prospectively enrolled in this study from Hunan Provincial People's Hospital between February 2019 and June 2019. All patients were tested for HE4 levels at baseline and follow-up. Endpoints of the study included cardiovascular death and heart failure-related hospitalization. RESULTS: A total of 96 patients with ICM were included for analysis. After a mean follow-up period of 263 (153-313) days, cardiovascular events were observed in 45 patients. Serum HE4 levels in patients with events were significantly higher than those in patients without events [188.70 (113.35-326.82) pmol/L versus 92.90 (61.50-123.20) pmol/L, P < 0.001]. Multivariate Cox regression analysis revealed that HE4 [χ2: 9.602, hazard ratio (HR): 1.003, 95% confidence interval (CI): 1.001-1.005, P = 0.002] and age [χ2: 4.55, HR: 1.044, 95% CI: 1.003-1.085, P = 0.033] were independent predictors of events. After adjusting for age and sex, the risk of events in patients with HE4 > 100.2 pmol/L was higher than that in patients with HE4 ≤ 100.2 pmol/L [HR: 3.372, 95% CI: 1.409-8.065, P < 0.001]. CONCLUSION: HE4 is an independent predictor of cardiovascular death and heart failure-related rehospitalization in patients with ICM.
