Trend of gastrointestinal and liver diseases in China: Results of the Global Burden of Disease Study, 2019.

BACKGROUND: China is one of the countries with the largest burden of gastrointestinal and liver diseases (GILD) in the world. The GILD constitutes various causes of mortality and disability. The study aimed to investigate the trend of GILD in China using the Global Burden of Diseases Study 2019 (GBD 2019) data resources from 1990 to 2019. METHODS: The data on the age-standardized mortality rates (ASMR) and disability-adjusted life years (DALYs) for GILD in China from 1990 to 2019 were collected from the GBD 2019 data resources. Furthermore, the ranking of the main causes of deaths and DALYs, as well as the trends of ASMR, DALYs, years of life lost (YLLs), and years of life lost due to disability (YLDs) per 1,000,000 in GILD were reported. RESULTS: The ASMR and DALYs for stomach cancer, liver cancer, and esophageal cancer, which ranked top three among the GILDs from 1990 to 2019, were gradually decreasing. Significant decreases in the ASMR and DALYs were found in diarrheal diseases and acute hepatitis (A, E, and C). However, noteworthy increases were found in those of colon and rectum cancer (CRC) and pancreatic cancer. Trend of DALYs, mortality, and YLLs rates for most of GILD were decreasing from 1990 to 2019, except the burden of CRC and pancreatic cancer with an increasing trend. The DALYs, mortality and YLLs of most GILD diseases showed decreasing trends from 1990 to 2019, except the burden of CRC and pancreatic cancer with an increasing trends. CONCLUSIONS: The result of the GBD 2019 showed that the rates of most GILDs decreased in China; however, gastrointestinal and liver cancer, such as stomach cancer still held the top ranking. Furthermore, the shift from infectious diseases to non-communicable causes among GILD burden is occurring and is likely to continue with many public health strategies implications.

Engineering exosomes derived from TNF-α preconditioned IPFP-MSCs enhance both yield and therapeutic efficacy for osteoarthritis.

BACKGROUND: The pathogenesis of osteoarthritis (OA) involves the progressive degradation of articular cartilage. Exosomes derived from mesenchymal stem cells (MSC-EXOs) have been shown to mitigate joint pathological injury by attenuating cartilage destruction. Optimization the yield and therapeutic efficacy of exosomes derived from MSCs is crucial for promoting their clinical translation. The preconditioning of MSCs enhances the therapeutic potential of engineered exosomes, offering promising prospects for application by enabling controlled and quantifiable external stimulation. This study aims to address these issues by employing pro-inflammatory preconditioning of MSCs to enhance exosome production and augment their therapeutic efficacy for OA. METHODS: The exosomes were isolated from the supernatant of infrapatellar fat pad (IPFP)-MSCs preconditioned with a pro-inflammatory factor, TNF-α, and their production was subsequently quantified. The exosome secretion-related pathways in IPFP-MSCs were evaluated through high-throughput transcriptome sequencing analysis, q-PCR and western blot analysis before and after TNF-α preconditioning. Furthermore, exosomes derived from TNF-α preconditioned IPFP-MSCs (IPFP-MSC-EXOsTNF-α) were administered intra-articularly in an OA mouse model, and subsequent evaluations were conducted to assess joint pathology and gait alterations. The expression of proteins involved in the maintenance of cartilage homeostasis within the exosomes was determined through proteomic analysis. RESULTS: The preconditioning with TNF-α significantly enhanced the exosome secretion of IPFP-MSCs compared to unpreconditioned MSCs. The potential mechanism involved the activation of the PI3K/AKT signaling pathway in IPFP-MSCs by TNF-α precondition, leading to an up-regulation of autophagy-related protein 16 like 1(ATG16L1) levels, which subsequently facilitated exosome secretion. The intra-articular administration of IPFP-MSC-EXOsTNF-α demonstrated superior efficacy in ameliorating pathological changes in the joints of OA mice. The preconditioning of TNF-α enhanced the up-regulation of low-density lipoprotein receptor-related protein 1 (LRP1) levels in IPFP-MSC-EXOsTNF-α, thereby exerting chondroprotective effects. CONCLUSION: TNF-α preconditioning constitutes an effective and promising method for optimizing the therapeutic effects of IPFP-MSCs derived exosomes in the treatment of OA.

High histone H3K18 lactylation level is correlated with poor prognosis in epithelial ovarian cancer.

Protein lactylation has a poor prognosis in malignant tumors, but its impact on the prognosis of epithelial ovarian cancer (EOC) remains unknown. We analyzed 112 patients with EOC. Immunohistochemical staining was used to detect the level of pan lactylation (Pan Kla) and histone H3K18 lactylation (H3K18la) in the EOC tissues and normal ovarian tissues. The result showed that the protein lactylation level in EOC was higher than in normal tissues. Then, we analyzed the relationship between overall survival (OS), progression-free survival (PFS) of EOC, and lactylation. The result showed that patients with high histone H3K18la levels had poorer OS (p=0.028) and PFS (p<0.001). Multivariate Cox regression analysis of PFS showed histone H3K18la was an independent risk factor (p=0.001). In addition, we found that both histone H3K18la and Pan Kla in the cytoplasm were associated with platinum recurrence time (p=0.002/p=0.003). The results also indicated that the H3K18la level was related to a tumor stage (p=0.037). Furthermore, we explored the effects of lactylation on the metastasis of ovarian cancer. The results indicated a significant increase in migration in the promoter group compared to the negative control group and inhibitor group. In conclusion, high histone H3K18la level is associated with poor prognosis in EOC. Protein lactylation may have a significant impact on EOC and could potentially be used as a target for EOC therapy in the future.

Impact of the pulmonary venous entry site morphology on postoperative pulmonary vein stenosis in total anomalous pulmonary venous connection patients.

BACKGROUND: To evaluate the association between the pulmonary vein (PV) entry site morphology after total anomalous pulmonary vein repair (TAPVC) and postoperative pulmonary vein stenosis (PVS). METHODS: Computed tomography (CT) examination was performed to determine the PV entry site morphology. The width of the PV confluence was divided by the width of the left atrium (LA) to obtain the cPV/LA index. The cPV/LA index was compared between patients with and without postoperative PVS. RESULTS: Fifty-one patients who had undergone CT after TAPVC repair were included, with a median cPV/LA index of 0.5 (interquartile range (IQR) = 0.349-0.654). Among them, 27 patients developed postoperative PVS. The median cPV/LA index after primary TAPVC repair was significantly lower in patients with PVS compared to those without PVS (0.367, IQR = 0.308-0.433 vs. 0.657, IQR = 0.571-0.783, P < 0.0001). Additionally, the cPV/LA index after surgical re-intervention for PVS was significantly smaller in patients who developed recurrent stenosis compared to those who remained free-from re-stenosis after surgical relief (0.459, IQR = 0.349-0.556; vs. 0.706, IQR = 0.628-0.810, P = 0.0045). CONCLUSION: A small PV confluence width is associated with the development of postoperative PVS and recurrent stenosis after surgical relief of PVS. Our results suggest that adequate bilateral pulmonary vein lateralization during TAPVC surgery is crucial.

[F-type forceps for assisted reduction in femoral shaft fractures surgery].

OBJECTIVE: To explore clinical efficacy of F-type forceps for assisted reduction in femoral shaft fracture reduction. METHODS: Forty-five patients with femoral shaft fracture treated with intramedullary nail and internal fixation from January 2019 to December 2021 were retrospectively analyzed and divided into two groups according to different reduction methods. In observation group, there were 21 patients, included 15 males and 6 females, aged from 27 to 92 years old with an average of (53.38±18.81) years old;9 patients on the left side, 12 patients on the right side;7 patients were type A, 8 patients were type B and 6 patients were type C according to AO fracture classification;the time from injury to operation ranged from 7 to 13 days with an average of (4.62±3.34) days;reduction was assisted by F-shaped forceps. In control group, there were 24 patients, including 17 males and 7 females, aged from 20 to 92 years old with an average of (51.96±20.43) years old;12 patients on the left side, 12 patients on the right side;11 patients were type A, 8 patients were type B and 5 patients were type C according to AO fracture classification;the time from injury to operation ranged from 2 to 13 days with an average of (6.29±3.04) days;traditional reset mode was adopted. Operative time, intraoperative blood loss, intraoperative fluoroscopy times, intraoperative open reduction ratio, clinical healing time of fracture, postoperative complications, hospital stay, hospital cost and Lysholm score of knee joint at 6 and 12 months after surgery were compared between two groups to evaluate clinical effect. RESULTS: All patients were followed up for 12 to 24 months with an average of (16.60±3.45) months. In observation group, operative time, intraoperative blood loss, intraoperative fluoroscopy times, open reduction cases, and clinical healing time of fractures were (58.19±7.93) min, (88.10±44.45) ml, (25.29±5.54) times, 0 case, (4.76±0.77) months, respectively;while in control group was (79.33±22.94) min, (222.92±144.45) ml, (47.46±26.25) times, 5 cases, (7.13±1.80) months, and the difference between two groups were statistically significant (P<0.05). There were no significant difference in postoperative complications, length of stay and hospitalization cost between two groups (P>0.05). At 6 months after surgery, Lysholm score of knee joint in observation group (88.62±4.48) was better than that in control group (79.21±8.91) (F=21.948, P=0.000). There were no significant difference in support use, pain and squat score between two groups (P>0.05). At 12 months after surgery, Lysholm scores of stair climbing and pain in observation group were (9.62±1.20) and (19.76±1.92), which were better than those in control group (7.83±2.04) and (21.88±2.88) (P<0.05). There were no significant difference in scores and total scores of other items between two groups (P>0.05). CONCLUSION: Compared with traditional reduction method, F-type forceps instrument could shorten operation time, reduce intraoperative blood loss, reduce intraoperative fluoroscopy times, accelerate clinical healing of fracture, and promote earlier functional recovery of knee joint.

High-glucose impact on UVB responses in human epidermal keratinocytes: Insights on diabetic skin's resistance to photocarcinogenesis.

Ultraviolet (UV) B-induced damage in human epidermal keratinocytes (HEKs) initiates photocarcinogenesis. However, how diabetes influences photocarcinogenesis is not well understood. To investigate the impact of high-glucose environments on responses to UVB, we cultured HEKs in normal-glucose (NG) or high-glucose (HG) conditions (G6 and G26), followed by UVB irradiation at 25 mJ/cm2 (G6UVB and G26UVB). We performed next-generation sequencing and analyzed HEKs' expression profiles bioinformatically to identify candidate genes and cellular responses involved. We found UVB induced consistent responses in both NG- and HG-cultivated HEKs, but it also triggered certain distinct processes and pathways specifically in the HG groups. The 459 differentially expressed (DE) genes in the HG groups revealed their roles in chromatin remodeling, nucleosome assembly, and interferon signaling activation. Moreover, the 29 DE genes identified in G26UVB/G6UVB comparison, including the potent tumor suppressor gene TFPI2, were considered key genes contributing to HEKs' altered response to UVB in HG environments. UVB irradiation induced significantly higher TFPI2 expression in HG-cultivated HEKs than their NG-cultivated counterpart. Finally, HG-cultivation significantly increased oxidative stress, cyclobutane pyrimidine dimer formation, and apoptosis, while reducing HEKs' viability after UVB irradiation. These changes under HG conditions probably mediate cell fate toward death and tumor regression. Overall, our findings provide evidence and associated molecular basis on how HG conditions reduce keratinocytes' photocarcinogenic potential following UVB exposure.

Prognostic Significance of VAV3 Gene Variants and Expression in Renal Cell Carcinoma.

Renal cell carcinoma (RCC) is characterized by high mortality and morbidity rates. Vav guanine nucleotide exchange factors (VAVs), crucial for signal transduction between cell membrane receptors and intracellular mediators, have been implicated in carcinogenesis. However, their potential prognostic value in RCC remains unclear. The impact of 150 common VAV polymorphisms on RCC risk and survival was investigated in a cohort of 630 individuals. Publicly available gene expression datasets were utilized to analyze VAV gene expression in relation to patient outcomes. The VAV3 rs17019888 polymorphism was significantly associated with RCC risk and overall survival after adjusting for false discovery rates. Expression quantitative trait loci analysis revealed that the risk allele of rs17019888 is linked to reduced VAV3 expression. Analysis of 19 kidney cancer gene expression datasets revealed lower VAV3 expression in RCC tissues compared to normal tissues, with higher expression correlating with better prognosis. Gene set enrichment analysis demonstrated that VAV3 negatively regulates the ubiquitin-proteasome system, extracellular matrix and membrane receptors, inflammatory responses, matrix metalloproteinases, and cell cycle pathways. Furthermore, elevated VAV3 expression was associated with increased infiltration of B cells, macrophages, and neutrophils into the RCC tumor microenvironment. Our findings suggest that VAV3 gene variants influence RCC risk and survival, contributing to a favorable prognosis in RCC.

Timely Shaver Treatment Removes Chronic Tophaceous Mass Improve Surgical Outcomes.

Background: Current treatments with urate-lowering therapy (ULT) are effective for most patients with gout. However, approximately 10% of these patients do not respond well to ULT and develop chronic tophus lesions. Objective: This study aimed to evaluate the efficacy of surgery involving the shaver technique against chronic tophus lesions. Methods: This single-center, retrospective cohort study included 217 patients who had cumulatively undergone 303 shaver-assisted procedures between 2002 and 2018. Surgical outcomes were assessed in terms of the length of hospital stay (LOS) and wound healing time. Results: LOS and wound healing time were longer in patients with a preoperative tophus infection and lower extremity lesions than in those without infection and with upper extremity lesions (respectively, LOS: 12.7 vs. 8.6 days; wound healing time: 22.7 vs. 16.3 days). However, factors such as age, sex, body mass index, renal function, or uricemia level exerted no significant effect on surgical outcomes. Conclusion: Surgery involving the shaver technique should be performed before tophus infection. Clinical outcomes tend to be better for upper extremity lesions than for lower extremity lesions.

Effects and trend of steroid dosage reduction during cardiac surgery: A three-year retrospective analysis at a tertiary medical center.

BACKGROUND: Current adult cardiac surgery guidelines recommend against the routine use of prophylactic intravenous corticosteroids during cardiopulmonary bypass (CPB) due to concerns about myocardial injury, despite their potential to reduce postoperative atrial fibrillation. Traditionally, a high dose of 1,000 mg of methylprednisolone was used to attenuate the inflammatory response associated with CPB. Our institution aligned with guideline recommendations and gradually reduced methylprednisolone dosages; thus, we reevaluated the impact on postoperative clinical outcomes. METHODS: Our study reviewed 1341 cases from a total of 1680 adult cardiac surgeries performed between June 2019 and May 2022 after excluding cases with off-pump procedures, ventricular assist device implantations, heart transplants, and aortic surgeries requiring systemic circulatory arrest. The study timely sorted periods including a baseline data from 2018, and other three periods since 2019 to analyze the effects of three different methylprednisolone dosage: 0 mg, 500 mg, and 1000 mg. We assessed the annual trends in methylprednisolone administration and compared morbidity and mortality rates across the groups. RESULTS: We observed a significant decline in steroid use, with no-steroid surgeries increasing from 23% to 66.5% by period 3. Despite the decreased use of steroids, our study showed no increase in mortality, new-onset atrial fibrillation, acute kidney injury, cerebrovascular event and prolonged ventilation when compared to baseline data. Notably, less surgical site infection rate was observed in the no-steroid group. CONCLUSION: The data indicates that a reduction or discontinuation of steroids during CPB can be performed without compromising patient outcomes. This could support a transition towards a more conservative use of steroids in adult cardiac surgery, aligning with current guidelines, and potentially reducing certain postoperative complications.

The miRNAs 203a/210-3p/5001-5p regulate the androgen/androgen receptor/YAP-induced migration in prostate cancer cells.

BACKGROUND: Prostate cancer (PCa) patients with elevated level of androgen receptor (AR) correlate with higher metastatic incidence. Protein expression of AR and its target gene prostate-specific antigen (PSA) are elevated in metastatic prostate tumors as compared to organ-confined tumors. Androgen treatment or elevation of AR promotes metastasis of PCa in cell culture and murine model. However, under androgen depleted condition, AR suppressed cell mobility and invasiveness of PCa cells. Androgen deprivation therapy in PCa patients is associated with higher risk of cancer metastasis. We therefore investigated the dual roles of AR and miRNAs on PCa metastasis. METHODS: The PC-3AR (PC-3 cells re-expressing AR) and LNCaP cells were used as PCa cell model. Transwell migration and invasion assay, wound-healing assay, zebrafish xenotransplantation assay, and zebrafish vascular exit assay were used to investigate the role of AR and androgen on PCa metastasis. Micro-Western Array, co-immunoprecipitation and Immunofluorescence were applied to dissect the molecular mechanism lying underneath. The miRNA array, miRNA inhibitors or plasmid, and chromatin immunoprecipitation assay were used to study the role of miRNAs on PCa metastasis. RESULTS: In the absence of androgen, AR repressed the migration and invasion of PCa cells. When androgen was present, AR stimulated the migration and invasion of PCa cells both in vitro and in zebrafish xenotransplantation model. Androgen increased phospho-AR Ser81 and yes-associated protein 1 (YAP), decreased phospho-YAP Ser217, and altered epithelial-mesenchymal transition (EMT) proteins in PCa cells. Co-IP assay demonstrated that androgen augmented the interaction between YAP and AR in nucleus. Knockdown of YAP or treatment with YAP inhibitor abolished the androgen-induced migration and invasion of PCa cells, while overexpression of YAP showed opposite effects. The miRNA array revealed that androgen decreased hsa-miR-5001-5p but increased hsa-miR-203a and hsa-miR-210-3p in PC-3AR cells but not PC-3 cells. Treatment with inhibitors targeting hsa-miR-203a/hsa-miR-210-3p, or overexpression of hsa-miR-5001-5p decreased YAP expression as well as suppressed the androgen-induced migration and invasion of PCa cells. Chromatin immunoprecipitation (ChIP) assay demonstrated that AR binds with promoter region of has-miR-210-3p in the presence of androgen. CONCLUSIONS: Our observations indicated that miRNAs 203a/210-3p/5001-5p regulate the androgen/AR/YAP-induced PCa metastasis.

Exploring Nurse Use of Digital Nursing Technology.

Technological developments and nursing shortages have become global trends. To solve the problem of shortage of healthcare professionals, technology may be used as a backup. Nurses constitute the largest working group in the healthcare system. Therefore, nurses are very important to the success of implementing digitization in hospitals. This cross-sectional study used the characteristics and adoption roles of innovation diffusion theory to understand technology use within the organization. Data were collected through structured questionnaires and open-ended questions from March 21 to May 31, 2022, in two hospitals in Taiwan. In total, 159 nurses agreed to participate in the study. The results of this study revealed that observability, simplicity, advantage, trialability, and compatibility positively improved the acceptance of digital nursing technology. In the distribution of users' innovative roles, early adopters had a significant impact on innovation characteristics and technology acceptance. Nurses in acute and critical care units perceived a greater comparative advantage and trial availability of digital nursing technology use than did those in general wards and outpatient clinics. In addition, based on user opinions and suggestions, the development of smart healthcare and the use of digital technology are expected to improve the quality of nursing care.

Comparative analysis of short- and long-term outcomes in laparoscopic versus open surgery for colorectal cancer patients undergoing hemodialysis.

PURPOSE: Although minimally invasive colorectal surgery has been proven to have a shorter hospital stay and fewer short-term complications than open surgery, the advantages of laparoscopic surgery for colorectal cancer patients undergoing hemodialysis have not been validated. This study compared the outcomes of open and laparoscopic approaches in these patients. MATERIALS AND METHODS: Between January 2007 and December 2020, we retrospectively analyzed the clinical data of 78 hemodialysis patients who underwent curative-intent, elective colorectal surgery. Patients were divided into two groups according to the surgical method: open and laparoscopic. RESULTS: Postoperative morbidity (p = 0.480) and mortality (p = 0.598) rates and length of hospital stay (28.8 vs. 27.5 days, p = 0.830) were similar between the groups. However, laparoscopic surgery patients had a shorter return to clear liquid, full liquid, or soft food time than open surgery patients (p < 0.001, p = 0.007, and p = 0.002, respectively). Disease-free survival and long-term cancer-specific survival rates were also similar between the two groups (p = 0.353 and p = 0.201, respectively). Multivariate analysis revealed that intraoperative blood transfusion was a risk factor for severe complications and mortality (OR 6.055; p = 0.046), and the odds ratio (OR) of laparoscopic surgery was not significantly greater than that of open surgery (OR = 0.537, p = 0.337). CONCLUSION: Although laparoscopic surgery did not result in hemodialysis patients having a shorter postoperative hospital stay, our results suggest that the laparoscopic approach is as safe as open surgery for hemodialysis patients and may be beneficial for shortening the return time to food intake.

Mesenchymal stem cell-derived extracellular vesicles in joint diseases: Therapeutic effects and underlying mechanisms.

Joint diseases greatly impact the daily lives and occupational functioning of patients globally. However, conventional treatments for joint diseases have several limitations, such as unsatisfatory efficacy and side effects, necessitating the exploration of more efficacious therapeutic strategies. Mesenchymal stem cell (MSC)-derived EVs (MSC-EVs) have demonstrated high therapeutic efficacyin tissue repair and regeneration, with low immunogenicity and tumorigenicity. Recent studies have reported that EVs-based therapy has considerable therapeutic effects against joint diseases, including osteoarthritis, tendon and ligament injuries, femoral head osteonecrosis, and rheumatoid arthritis. Herein, we review the therapeutic potential of various types of MSC-EVs in the aforementioned joint diseases, summarise the mechanisms underlying specific biological effects of MSC-EVs, and discuss future prospects for basic research on MSC-EV-based therapeutic modalities and their clinical translation. In general, this review provides an in-depth understanding of the therapeutic effects of MSC-EVs in joint diseases, as well as the underlying mechanisms, which may be beneficial to the clinical translation of MSC-EV-based treatment. The translational potential of this article: MSC-EV-based cell-free therapy can effectively promote regeneration and tissue repair. When used to treat joint diseases, MSC-EVs have demonstrated desirable therapeutic effects in preclinical research. This review may supplement further research on MSC-EV-based treatment of joint diseases and its clinical translation.

Recurrence rates after functional surgery versus amputation for nail squamous cell carcinoma not involving the bone: A systematic review.

Background Nail unit squamous cell carcinoma (nSCC) is a malignant subungual tumour. Although it has a low risk of metastasis and mortality, the tumour has a significant local recurrence rate. There is insufficient data to determine whether functional surgery is less effective than amputation for nSCC that does not involve the bone. Objectives We aimed to investigate existing data on the outcomes of functional surgery and amputation for nSCC without bone invasion. Materials and Methods We carried out an extensive search in PubMed, Embase, Cochrane Library, Web of Science, and Scopus for appropriate English-language academic papers, starting with the creation of individual resources until February 23, 2023. The main outcome was local recurrence. Initially, 2191 studies related to nSCC were selected. Information from every research study was retrieved and subdivided, comprising the year of publication, period, number of patients, age, gender distribution, tumour stage, type of intervention, number of recurrences, and follow-up period. Results Ten independent studies (319 lesions) were finally selected. Mohs micrographic surgery was the most reported surgical modality, followed by wide surgical excision and amputation. Local recurrence rates between Mohs micrographic surgery, wide surgical excision and amputation treatment were nearly identical. Other surgical methods included limited surgical excision, partial ablation, and limited excision until the clearing of margins, with recurrence rates up to 50%. Conclusions Given the functional impairment and psychological distress associated with phalanx amputation, functional surgery, including Mohs micrographic surgery and wide surgical excision , should be the preferred therapy for nSCC without bone involvement. Amputation should remain the preferred therapy for nSCC that involves the bone. Partial excision should be avoided. Further studies on whether Mohs micrographic surgery or wide surgical excision is a better option for nSCC not involving the bone are required.

Airway Anomalies in Pediatric Patients After Surgery for Congenital Heart Disease: Single-Center Retrospective Cohort Study, Taiwan 2017-2020.

OBJECTIVES: Airway anomalies increase risk of morbidity and mortality in postoperative pediatric patients with congenital heart disease (CHD). We aimed to identify airway anomalies and the association with intermediate outcomes in patients undergoing surgery for CHD. DESIGN: Single-center, hospital-based retrospective study in Taiwan, 2017-2020. SETTING: A tertiary referral hospital in Taiwan. PATIENTS: All pediatric patients who underwent surgery for CHD and were admitted to the PICU and had data about airway evaluation by cardiopulmonary CT scan or bronchoscopy. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among 820 CHD patients identified as having undergone airway evaluation in the PICU, 185 (22.6%) were diagnosed with airway anomalies, including structural lesions in 146 of 185 (78.9%), and dynamic problems were seen in 87 of 185 (47.0%). In this population, the explanatory factors associated with greater odds (odds ratio [OR]) of airway anomaly were premature birth (OR, 1.90; p = 0.002), genetic syndromes (OR, 2.60; p < 0.001), and in those with preoperative ventilator use (OR, 4.28; p < 0.001). In comparison to those without airway anomalies, the presence of airway anomalies was associated with higher hospital mortality (11.4% vs. 2.7%; p < 0.001), prolonged intubation days (8 d [1-27 d] vs. 1 d [1-5 d]; p < 0.001), longer PICU length of stay (23 d [8-81 d] vs. 7 d [4-18 d]; p < 0.001), and greater hazard of intermediate mortality (adjusted hazard ratio, 2.60; p = 0.001). CONCLUSIONS: In our single-center retrospective study, 2017-2020, between one-in-five and one-in-four of our postoperative CHD patients undergoing an airway evaluation had airway anomalies. Factors associated with greater odds of airway anomaly included, those with premature birth, or genetic syndromes, and preoperative ventilator use. Overall, in patients undergoing airway evaluation, the finding of an airway anomalies was associated with longer postoperative intubation duration and greater hazard of intermediate mortality.

The involvement of tumor necrosis factor receptor-associated factor 6 in regulating immune response by NF-κB at pre-molt stage of Chinese mitten crab (Eriocheir sinensis).

Molting is a crucial biological process of crustaceans. Crustaceans go through three separate stages throughout their molting process, including pre-molt, post-molt and inter-molt. However, the exact mechanism of immunological modulation during molting remains unclear. Tumor necrosis factor receptor-associated factor 6 (TRAF6) has been extensively documented to participate in immune defense. In the present study, a TRAF6 gene with two TRAF-type zinc finger domains was identified from Eriocheir sinensis (designed as EsTRAF6), and its role in regulating immune response during molting process was explored. The mRNA expression level of EsTRAF6 at pre-molt stage was higher than that at post-molt stage and inter-molt stage. After Aeromonas hydrophila stimulation, the expression levels of EsTRAF6, EsRelish and anti-lipopolysaccharide factors (ALFs) genes exhibited a considerable increase at three molting stages. Subsequently, the expression patterns of EsTRAF6 and EsRelish in response to the treatment with 20-hydroxyecdysone (20E) were examined. The mRNA expression of EsTRAF6 and EsRelish were significantly increased at 12 h after 20E injection. Additionally, the protein expression level of TRAF6 was also up-regulated in 20E group compared to control group. Furthermore, the role of EsTRAF6 in regulating the anti- ALFs expression at pre-molt stage post A. hydrophila stimulation was investigated. Following the inhibition of the EsTRAF6 transcript using RNAi or the injection of inhibitor (TMBPS), there was a notable decrease of the EsALF1, EsALF2 and EsALF3 transcripts. Moreover, a significant reduction in the phosphorylation level of NF-κB at pre-molt stage was observed after A. hydrophila stimulation in TRAF6-inhibited crabs. Collectively, our results suggest that EsTRAF6 could be induced by 20E and promoted the EsALFs expression by activating NF-κB at pre-molt stage, which provides a novel insight into the research of immune regulatory mechanism during the process of molting of crustaceans.

Glaucine inhibits hypoxia-induced angiogenesis and attenuates LPS-induced inflammation in human retinal pigment epithelial ARPE-19 cells.

Glaucine is an aporphine alkaloid with anti-inflammatory, bronchodilator and anti-cancer activities. However, the effects of glaucine in the regulation of age-related macular degeneration (AMD) remain unclear. Herein, we aimed to investigate the anti-angiogenetic and anti-inflammatory effects of glaucine in ARPE-19 cells. ARPE-19 cells were treated with N-(methoxyoxoacetyl)-glycine, methyl ester (DMOG) and cobalt chloride (CoCl2) for induction of hypoxia, while lipopolysaccharide (LPS) treatment was used for elicitation of inflammatory response. Cell viability was analyzed using 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay. The expression of hypoxia-inducible factor (HIF-1α) and vascular endothelial growth factor (VEGF) were measured by Western blot. The secretion of VEGF, interleukin (IL)-6 and monocyte chemoattractant protein-1 (MCP-1) was detected using enzyme-linked immunosorbent assay (ELISA). Human umbilical vein endothelial cells (HUVECs) were used for tube formation analysis. Expression of HIF-1α and secretion of VEGF were significantly increased under DMOG and CoCl2 induction, whereas glaucine significantly attenuated both HIF-1α expression and VEGF secretion by DMOG- and CoCl2-induced ARPE-19 cells. In addition, glaucine suppressed the tube formation by DMOG- and CoCl2-induced HUVEC cells. Moreover, glaucine also attenuated the production of IL-6 and MCP-1 by LPS-induced ARPE-19 cells. This study indicated that glaucine exhibited anti-angiogenic and anti-inflammatory effects, suggesting that glaucine might have benefits for the treatment of AMD.

FOXO-regulated DEAF1 controls muscle regeneration through autophagy.

The commonality between various muscle diseases is the loss of muscle mass, function, and regeneration, which severely restricts mobility and impairs the quality of life. With muscle stem cells (MuSCs) playing a key role in facilitating muscle repair, targeting regulators of muscle regeneration has been shown to be a promising therapeutic approach to repair muscles. However, the underlying molecular mechanisms driving muscle regeneration are complex and poorly understood. Here, we identified a new regulator of muscle regeneration, Deaf1 (Deformed epidermal autoregulatory factor-1) - a transcriptional factor downstream of foxo signaling. We showed that Deaf1 is transcriptionally repressed by FOXOs and that DEAF1 targets to Pik3c3 and Atg16l1 promoter regions and suppresses their expression. Deaf1 depletion therefore induces macroautophagy/autophagy, which in turn blocks MuSC survival and differentiation. In contrast, Deaf1 overexpression inactivates autophagy in MuSCs, leading to increased protein aggregation and cell death. The fact that Deaf1 depletion and its overexpression both lead to defects in muscle regeneration highlights the importance of fine tuning DEAF1-regulated autophagy during muscle regeneration. We further showed that Deaf1 expression is altered in aging and cachectic MuSCs. Manipulation of Deaf1 expression can attenuate muscle atrophy and restore muscle regeneration in aged mice or mice with cachectic cancers. Together, our findings unveil an evolutionarily conserved role for DEAF1 in muscle regeneration, providing insights into the development of new therapeutic strategies against muscle atrophy.Abbreviations: DEAF1: Deformed epidermal autoregulatory factor-1; FOXO: Forkhead box O; MuSC: Muscle Stem Cell; PAX7: Paired box 7; PIK3C3: Phosphatidylinositol 3-kinase catalytic subunit type 3.

Concurrent epirubicin and trastuzumab use increases complete pathological response rate without additional cardiotoxicity in patients with human epidermal growth factor receptor 2-positive early breast cancer: A meta-regression analysis.

BACKGROUND: Due to cardiotoxicity concerns, the concurrent use of epirubicin and trastuzumab has not been fully studied. This study aimed to examine the cardiotoxicity and pathological complete response (pCR) rate associated with the concurrent regimens in patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer (EBC). METHODS: We conducted a systematic search for relevant literature in the NCBI/PubMed, the Cochrane database, and international conference abstracts for phase II or III randomized controlled trials between January 1, 2000, and February 28, 2021, focusing on the concurrent regimens in patients with HER2-positive EBC. To compare the risk of cardiotoxicity and the odds of the pCR rate, we performed linear meta-regression analyses to investigate the effects of multiple covariates. RESULTS: We analyzed 7 neoadjuvant trials involving the concurrent use of epirubicin and trastuzumab with 1797 patients. The median cumulative dose of epirubicin used was 300 mg/m2, with a total of 96 reported adverse cardiac events. The concurrent regimens did not result in a significant increase in cardiotoxicity compared to nonconcurrent regimens (risk ratio [RR] = 1.18, 95% confidence interval [CI] = 0.68-2.05). Compared with nonconcurrent or non-anthracycline-containing regimens, concurrent regimens were associated with a significant increase in the pCR rate (odds ratio = 1.48, 95% CI = 1.04-2.12). The linear fixed-effects meta-regression analysis indicated that in trials including more patients with hormone receptor-positive EBC, the RR of cardiotoxicity significantly increased with concurrent regimens, and the pCR rate became less significant. CONCLUSIONS: The combination of trastuzumab and a low dose of epirubicin positively impacted the pCR rate without a significant increase in cardiotoxicity. We recommend exploring concurrent regimens for HR-negative, HER2-positive tumors to enhance pCR rates, with caution advised for HR-positive tumors due to potential cardiotoxicity.

Trends analysis of cancer incidence, mortality, and survival for the elderly in the United States, 1975-2020.

BACKGROUND: Cancer burden from the elderly has been rising largely due to the aging population. However, research on the long-term epidemiological trends in cancer of the elderly is lacking. METHODS: Registry data of this population-based cross-sectional study were from the Surveillance, Epidemiology, and End Results (SEER) database. The study population aged 65 years or more, from geographically distinct regions. Joinpoint regression and JP Surv method were used to analyze cancer trends and survival. RESULTS: Mortality rate during 1975-2020 decreased from 995.20 to 824.99 per 100,000 elderly persons, with an average annual decrease of 0.421% (95% CI, 0.378-0.464). While overall incidence increased with no significance. Prostate (29%) and breast (26%) cancer were the most common malignancies, respectively, in elderly males and females, and the mortality for both of the two (prostate 15%, breast 14%) ranked just behind lung and bronchus cancer, which had the highest mortality rates in males (29%) and females (23%). Many cancers showed adverse trends in the latest follow-up periods (the last period calculated by the Joinpoint method). For intrahepatic cholangiocarcinoma, incidence (male Annual Percentage Change [APC] = 7.4*; female APC = 6.7*) and mortality (male APC = 3.0*; female APC = 3.3*) increased relatively fast, and its survival was also terrible (3-year survival only 10%). Other cancers with recent increasing mortality included cancer of anus, anal canal and anorectum, retroperitoneum, pleura, peritoneum, etc. Most cancers had favorable trends of survival during the nearest follow-up period. CONCLUSION: Against the background of overall improvement, many cancers showed adverse trends. Further research for the underlying mechanisms and targeted implements towards adverse trends is also urgent.
