Clinical and socioeconomic factors predicting return-to-work times after cholecystectomy.

BACKGROUND: Cholecystectomy, a type of surgery commonly performed globally, has possible mutual effects on the socioeconomic conditions of different countries due to various postoperative recovery times. AIMS: This study evaluated the medical and socioeconomic factors affecting delayed return-to-work (RTW) time after elective cholecystectomy. METHODS: This retrospective study analysed patients who underwent elective cholecystectomy for benign gallbladder diseases from January 2022 to April 2023. The patients' medical and socioeconomic data were collected to investigate the clinical and socioeconomic factors correlated with RTW time of >30 days after surgery. RESULTS: This study included 180 consecutive patients. Significant correlations were found between delayed RTW time (>30 days) and age (odds ratio [OR]: 1.059, 95% confidence interval [CI] 1.008-1.113, P = 0.024), lack of medical insurance (OR: 2.935, 95% CI 1.189-7.249, P = 0.02) and high-intensity labour jobs (OR: 3.649, 95% CI 1.495-8.909, P = 0.004). Patients without medical insurance (26.6 versus 18.9 days) and those with high-intensity labour jobs (23.9 versus 18.8 days) had a higher mean RTW time than those with insurance and a less-intense labour job (P < 0.001). CONCLUSIONS: After cholecystectomy, older age, lack of medical insurance and high-intensity labour job were correlated with a delayed RTW time. Informing patients about their expected RTW time after surgery can help reduce costs.

A standard set of outcome measures for the comprehensive assessment of oral health and occlusion in individuals with osteogenesis imperfecta.

BACKGROUND: Osteogenesis imperfecta (OI) is a group of inherited connective tissue disorders of varying severity characterized by bone fragility. The primary objective of this international multidisciplinary collaboration initiative was to reach a consensus for a standardized set of clinician and patient-reported outcome measures, as well as associated measuring instruments for dental care of individuals with OI, based on the aspects considered important by both experts and patients. This project is a subsequent to the Key4OI project initiated by the Care4BrittleBones foundation which aims to develop a standard set of outcome measures covering a large domain of factors affecting quality of life for people with OI. An international team of experts comprising orthodontists, pediatric dentists, oral and maxillofacial surgeons, and prosthetic dentists used a modified Delphi consensus process to select clinician-reported outcome measures (CROMs) and patient-reported outcome measures (PROMs) to evaluate oral health in individuals with OI. Important domains were identified through a literature review and by professional expertise (both CROMs and PROMs). In three focus groups of individuals with OI, important and relevant issues regarding dental health were identified. The input from the focus groups was used as the basis for the final set of outcome measures: the selected issues were attributed to relevant CROMs and, when appropriate, matched with validated questionnaires to establish the final PROMs which represented best the specific oral health-related concerns of individuals with OI. RESULTS: Consensus was reached on selected CROMs and PROMs for a standard set of outcome measures and measuring instruments of oral health in individuals with OI. CONCLUSIONS: Our project resulted in consensus statements for standardization oral health PROMs and CROMs in individuals with OI. This outcome set can improve the standard of care by incorporating recommendations of professionals involved in dental care of individuals with OI. Further, it can facilitate research and international research co-operation. In addition, the significant contribution of the focus groups highlights the relevance of dental and oral health-related problems of individuals with OI.

[Metrology analysis and thoughts of literatures on tinnitus associated with sudden deafness based on CiteSpace].

Objective: To explore the incidence of sudden deafness accompanied with tinnitus, the selection of examination protocols and treatment, and to provide reference for the establishment of new guidelines for sudden deafness. Methods: CiteSpace software was used for analysis and data mining to analyze and summarize the computer-retrieved articles on diagnostic examination and treatment of sudden deafness accompanied with tinnitus collected from CNIC, Wanfang and Web of Science databases from 2011 to 2021. Results: A total of 207 randomized controlled studies were retrieved in this study, including 121 in Chinese and 86 in English. Finally, 74 Chinese literatures and 16 English literatures were included. Among the 74 valid Chinese literatures, 64 (86.5%) were accompanied with tinnitus, 58 (78.4%) with dizziness/vertigo, 25 (33.8%) with aural fullness, 10 (13.5%) with headache, 4 (5.4%) with insomnia, 4 (5.4%) with a mixture of dizziness and tinnitus, and 2 (2.7%) with vomiting. Among the 16 English literatures, 15 (93.8%) were accompanied with tinnitus, 12 (75.0%) with vertigo, 1 (6.3%) with aural fullness, and 1 (6.3%) with a mixture of various symptoms. Among the 64 Chinese articles mentioning tinnitus, only 9 mentioned tinnitus matching tests, and 1 mentioned that the treatment for tinnitus accompanying symptoms was sound therapy and psychological counseling. The incidence rates of tinnitus accompanying four different types of sudden deafness, from low to high, are as follows: low-to-mid frequency, 82.4%; mid-to-high frequency, 90.7%; complete deafness, 92.4%; and flat type, 92.8%. Conclusion: Tinnitus is the most common accompanying symptom of sudden deafness, and tinnitus matching test is an effective evaluation method. When establishing a scientific, comprehensive, and systematic diagnosis and treatment system or guidelines for sudden deafness, attention should be paid to the diagnosis and treatment of tinnitus symptoms and their adverse psychological reactions, in order to reduce the incidence of tinnitus patients in the later stage of recovery from sudden deafness.

[Hemophagocytic syndrome secondary to invasive NK cell leukemia and T-cell lymphoma treated with the modified MINE protocol: report of three cases and literature review].

Lymphoma-associated hemophagocytic syndrome is aggressive with rapid progression, particularly in NK/T cell lymphoma. The MINE regimen is a salvage treatment for aggressive non-Hodgkin lymphoma. In our center, the modified MINE regimen was applied to treat three patients with hemophagocytic syndrome secondary to aggressive NK cell leukemia and T-cell lymphoma. The modified MINE regimen showed good efficacy against NK/T cell lymphoma, control of the inflammatory state of secondary hemophagocytic syndrome, and good tolerability.

[Porphyromonas gingivalis promotes the occurrence of esophageal squamous cell carcinoma via an inflammatory microenvironment].

Objective: To investigate the role of an inflammatory microenvironment induced by Porphyromonasgingivalis (P. gingivalis) in the occurrence of esophageal squamous cell carcinoma (ESCC) in mice. Methods: A total of 180 C57BL/6 mice were randomly divided into 6 groups, i.e. control group, P. gingivalis group, 4NQO group, 4NQO + P. gingivalis group, 4NQO + P. gingivalis + celecoxib group, and 4NQO + P. gingivalis + antibiotic cocktail (ABC, including metronidazole, neomycin, ampicillin, and vancomycin) group, with 30 mice in each group, using the random number table. All mice were normalized by treatment with ABC in drinking water for 2 weeks. In the following 2 weeks, the mice in the control group and the P. gingivalis group were given drinking water, while the other 4 groups were treated with 30 µg/ml 4NQO in the drinking water. In weeks 11-12, the mice in the P. gingivalis group, the 4NQO + P. gingivalis group, the 4NQO + P. gingivalis + celecoxib group, and the 4NQO + P. gingivalis + ABC group were subjected to ligation of the second molar in oral cavity followed by oral P. gingivalis infection thrice weekly for 24 weeks in weeks 11-34. In weeks 13-34, the mice in 4NQO + P. gingivalis+celecoxib group and 4NQO + P. gingivalis + ABC group were administered with celecoxib and ABC for 22 weeks, respectively. At the end of 34 weeks, gross and microscopic alterations were examined followed by RT-qPCR and immunohistochemistry to examine the expression profiles of inflammatory- and tumor-molecules in esophagi of mice. Results: At 34 weeks, 4NQO treatment alone did not affect the foci of papillary hyperproliferation, diseased area, and the thickness of the esophageal wall, but significantly enhanced the foci of hyperproliferation (median 1.00, P＜0.05) and mild/moderate dysplasia (median 2.00, P＜0.01). In addition, the expression levels of IL-6 [8.35(3.45,8.99)], IL-1ß [6.90(2.01,9.72)], TNF-α [12.04(3.31,14.08)], c-myc [2.21(1.80,3.04)], pSTAT3, Ki-67, and pH2AX were higher than those in the control group. The pathological changes of the esophageal mucosa were significantly more overt in the 4NQO + P. gingivalis group in terms of the foci of papillary hyperproliferation (median 2.00), diseased area (median 2.51 mm2), the thickness of the esophageal wall (median 172.52 µm), the foci of hyperproliferation (median 1.00, P＜0.05), and mild/moderate dysplasia (median 1.00, P＜0.01). In mice of the 4NQO + P. gingivalis group, the expression levels of IL-6 [12.27(5.35,22.08)], IL-1ß [13.89(10.04,15.96)], TNF-α [19.56(6.07,20.36)], IFN-γ [11.37(8.23,20.07)], c-myc [2.62(1.51,4.25)], cyclin D1 [4.52(2.68,7.83)], nuclear pSTAT3, COX-2, Ki-67, and pH2AX were significantly increased compared with the mice in the control group. In mice of the 4NQO + P. gingivalis group, the diseased area, invasive malignant foci as well as pSTAT3 and pH2AX expression were significantly blunted by celecoxib. Treatment with ABC markedly reduced the papillary hyperproliferative foci, invasive malignant foci, and pSTAT3 expression but not pH2AX. Conclusions: P. gingivalis promotes the occurrence of esophageal squamous cell carcinoma in mice by inducing an inflammatory microenvironment primed with 4NQO induced DNA damage. Clearance of P. gingivalis with ABC or anti-inflammatory intervention holds promise for prevention of esophageal squamous cell malignant pathogenesis via blockage of IL-6/STAT3 signaling and amelioration of inflammation.

[Gene mutation characteristics of clinical stage â A lung adenocarcinoma and their relations with patients' long-term prognosis].

Objective: To explore the gene mutation characteristics and the relationship between gene mutations and long-term prognosis in clinical stage ⅠA lung adenocarcinoma patients. Methods: A retrospective analysis was conducted on 63 clinical stage ⅠA lung adenocarcinoma patients who underwent surgical resection at the Cancer Hospital of the Chinese Academy of Medical Sciences from January 2007 to October 2012, with documented postoperative recurrence or metastasis, as well as those who had a follow-up duration of 10 years or more without recurrence or metastasis. Whole exome sequencing (WES) technology was used to analyze the gene mutation profiles in tumor tissues and univariate and multivariate Cox regression analysis were used to clarify the influencing factors for patient prognosis. Results: After long term follow-up, 13 out of the 63 patients (21%) experienced recurrence or metastasis. WES technology analysis revealed that the most common tumor related gene mutations occurred in epidermal growth factor receptor (EGFR), with a mutation rate of 65.1% (41/63), followed by tumor protein p53 (TP53), fatatypical cadherin 1 (FAT1), low density lipoprotein receptor-related protein 1B (LRP1B), mechanistic target of rapamycin (MTOR), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit gamma (PIK3CG), and SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily A, member 4 (SMARCA4), with mutation rates of 30.2% (19/63), 20.6% (13/63), 15.9% (10/63), 15.9% (10/63), 15.9% (10/63), and 15.9% (10/63), respectively. Multivariate Cox regression analysis showed that PIK3CG mutations (HR=21.52, 95% CI: 3.19-145.01),smoothened (SMO) mutations (HR=35.28, 95% CI: 3.12-398.39), catenin beta 1 (CTNNB1) mutations (HR=332.86, 95% CI: 15.76-7 029.05), colony stimulating factor 1 receptor (CSF1R) mutations (HR=8 109.60, 95% CI: 114.19-575 955.17), and v-Raf murine sarcoma viral oncogene homolog B (BRAF) mutations (HR=23.65, 95% CI: 1.86-300.43) were independent risk factors affecting the prognosis of clinical stage ⅠA lung adenocarcinoma patients. Conclusions: PIK3CG, SMO, CTNNB1, CSF1R, BRAF gene mutations are closely related to long-term recurrence or metastasis in clinical stage ⅠA lung adenocarcinoma. Patients with these gene mutations should be given closer clinical attention.

Imputation strategies for low-coverage whole-genome sequencing data and their effects on genomic prediction and genome-wide association studies in pigs.

The uncertainty resulting from missing genotypes in low-coverage whole-genome sequencing (LCWGS) data complicates genotype imputation. The aim of this study is to find out an optimal strategy for accurately imputing LCWGS data and assess its effectiveness for genomic prediction (GP) and genome-wide association study (GWAS) on economically important traits of Large White pigs. The LCWGS data of 1 423 Large White pigs were imputed using three different strategies: (1) using the high-coverage whole-genome sequencing (HCWGS) of 30 key progenitors as the reference panel (Ref_LG); (2) mixing HCWGS of key progenitors with LCWGS (Mix_HLG) and (3) self-imputation in LCWGS (Within_LG). Additionally, to compare the imputation effects of LCWGS, we also imputed SNP chip data of 1 423 Large White pigs to the whole-genome sequencing level using the reference panel consisting of key progenitors (Ref_SNP). To evaluate effects of the imputed sequencing data, we compared the accuracies of GP and statistical power of GWAS for four reproductive traits based on the chip data, sequencing data imputed from chip data and LCWGS data using an optimal strategy. The average imputation accuracies of the Within_LG, Ref_LG and Mix_HLG were 0.9893, 0.9899 and 0.9875, respectively, which were higher than that of the Ref_SNP (0.8522). Using the imputed sequencing data from LCWGS with the Ref_LG imputation strategy, the accuracies of GP for four traits improved by approximately 0.31-1.04% compared to the chip data, and by 0.7-1.05% compared to the imputed sequencing data from chip data. Furthermore, by using the sequence data imputed from LCWGS with the Ref_LG, 18 candidate genes were identified to be associated with the four reproductive traits of interest in Large White pigs: total number of piglets born - EPC2, MBD5, ORC4 and ACVR2A; number of piglets born healthy - IKBKE; total litter weight of piglets born alive - HSPA13 and CPA1; gestation length - GTF2H5, ITGAV, NFE2L2, CALCRL, ITGA4, STAT1, HOXD10, MSTN, COL5A2 and STAT4. With the exception of EPC2, ORC4, ACVR2A and MSTN, others represent novel candidates. Our findings can provide a reference for the application of LCWGS data in livestock and poultry.

[Early experience with mechanical hemodynamic support for catheter ablation of malignant ventricular tachycardia].

Objective: To explore the role of mechanical hemodynamic support (MHS) in mapping and catheter ablation of patients with hemodynamically unstable ventricular tachycardia (VT), report single-center experience in a cohort of consecutive patients receiving VT ablation during MHS therapy, and provide evidence-based medical evidence for clinical practice. Methods: This was a retrospective cohort study. Patients with hemodynamically unstable VT who underwent catheter ablation with MHS at Beijing Anzhen Hospital, Capital Medical University between August 2021 and December 2023 were included. Patients were divided into rescue group and preventive group according to the purpose of treatment. Their demographic data, periprocedural details, and clinical outcomes were collected and analyzed. Results: A total of 15 patients with hemodynamically unstable VT were included (8 patients in the rescue group and 7 patients in the preventive group). The acute procedure was successful in all patients. One patient in the rescue group had surgical left ventricular assist device (LVAD) implantation, remaining 14 patients received extracorporeal membrane oxygenation (ECMO) for circulation support. ECMO decannulation was performed in 12 patients due to clinical and hemodynamic stability, of which 6 patients were decannulation immediately after surgery and the remaining patients were decannulation at 2.0 (2.5) d after surgery. Two patients in the rescue group died during the index admission due to refractory heart failure and cerebral hemorrhage. During a median follow-up of 30 d (1 d to 12 months), one patient with LVAD had one episode of ventricular fibrillation at 6 months after discharge, and no further episodes of ventricular fibrillation and/or VT occurred after treatment with antiarrhythmic drugs. No malignant ventricular arrhythmia occurred in the remaining 12 patients who were followed up. Conclusions: MHS contributes to the successful completion of mapping and catheter ablation in patients with hemodynamically unstable VT, providing desirable hemodynamic status for emergency and elective conditions.

[Correlation between coronary artery tortuosity and poor prognosis in patients with septal hypertrophic cardiomyopathy].

Objective: To investigate the incidence of coronary artery tortuosity and its correlation with poor prognosis in patients with septal hypertrophic cardiomyopathy (HCM). Methods: This was a retrospective cohort study. Patients with septal HCM who were hospitalized in Fuwai Central China Cardiovascular Hospital and Zhengzhou University People's Hospital between December 1, 2017 and June 10, 2021 were selected. Non-HCM patients were matched by gender, age, and hypertension as control group. Septal HCM was divided into two groups based on the presence or absence of coronary artery tortuosity. Clinical baseline data and coronary angiography findings were compared using a multifactorial logistic analysis of the risk factors for coronary artery tortuosity. Patients were followed up until July 1, 2022, with the primary outcome being the composite endpoint of malignant arrhythmia, ischemic stroke and all-cause death. Incidence densities were compared between the coronary artery tortuosity and non-coronary artery tortuosity groups of septal HCM patients. The Cox risk-ratio model was used to analyze risk factors for primary outcomes in septal HCM patients. Results: There were 156 patients in the septal HCM group and 156 patients in the control group, both aged (57.0±11.4) years, and 75 (48.1%) were female. The incidence of coronary artery tortuosity was significantly higher in the septal HCM group than in the control group (63.5% vs. 36.5%, P<0.01), and the coronary artery tortuosity score was also higher in the septal HCM group than in the control group (P<0.01). Multiple logistic regression analysis showed that septal HCM was a risk factor for coronary artery tortuosity (OR=3.27, 95%CI: 2.02-5.29, P<0.01). In the septal HCM patients, after (2.5±1.2) years of follow-up, the incidence density of primary outcome was significantly higher in the coronary artery tortuosity group than in the non-coronary artery tortuosity group (P=0.02), while each on-point in coronary artery tortuosity score increased the risk of primary outcome by 53% for septal HCM patients (HR=1.53, 95%CI: 1.26-1.86, P<0.01). Conclusions: Patients with septal HCM are more prone to suffer coronary artery tortuosity and suffer from it to a greater extent. Coronary artery tortuosity is an important risk factor for adverse events in patients with septal HCM.

[A single-center retrospective study of salvage allogeneic hematopoietic stem cell transplantation pretreated with MeCBA regimen for refractory/relapsed acute myeloid leukemia].

Thirty refractory relapsed acute myeloid leukemia (R/R AML) patients who received salvage allo-HSCT with MeCBA conditioning regimen from January 2018 to June 2022 at Henan Cancer Hospital were included, and their clinical data were reviewed. There were 16 males and 14 females among the 30 patients with a median age of 37 (16-53) years. There were 3 sibling allograft donor transplants, 1 unrelated donor transplant, and 26 haplotype transplants. The median course of pre-transplant chemotherapy was 4 (3-22). The time of neutrophil engraftment was 14 (9-22) days and 18 (10-40) days for platelet. The 30-day cumulative incidence of neutrophil engraftment was 100% and the 100-day cumulative incidence of platelet engraftment was 96.7% (95% CI 85.4% -97.5% ). 22 (73.3% ) patients experienced grade 1-2 gastrointestinal reactions, and there was no grade 3-4 organ toxicity. With a median follow-up of 37.1 months, the overall survival (OS) rate, event-free survival (EFS) rate, cumulative recurrence rate (CIR), and non-recurrence mortality (NRM) rate at 3 years after transplantation were 70.0% (95% CI 50.3% -83.1% ), 65.3% (95% CI 44.8% -79.8% ), 21.2% (95% CI 9.2% -44.4% ) and 16.7% (95% CI 7.3% -35.5% ), respectively.

Adoptive transfer of personalized neoantigen-reactive TCR-transduced T cells in metastatic colorectal cancer: phase 2 trial interim results.

Adoptive cell transfer (ACT) with neoantigen-reactive T lymphocytes can mediate cancer regression. Here we isolated unique, personalized, neoantigen-reactive T cell receptors (TCRs) from tumor-infiltrating lymphocytes of patients with metastatic gastrointestinal cancers and incorporated the TCR α and ß chains into gamma retroviral vectors. We transduced autologous peripheral blood lymphocytes and adoptively transferred these cells into patients after lymphodepleting chemotherapy. In a phase 2 single-arm study, we treated seven patients with metastatic, mismatch repair-proficient colorectal cancers who had progressive disease following multiple previous therapies. The primary end point of the study was the objective response rate as measured using RECIST 1.1, and the secondary end points were safety and tolerability. There was no prespecified interim analysis defined in this study. Three patients had objective clinical responses by RECIST criteria including regressions of metastases to the liver, lungs and lymph nodes lasting 4 to 7 months. All patients received T cell populations containing ≥50% TCR-transduced cells, and all T cell populations were polyfunctional in that they secreted IFNγ, GM-CSF, IL-2 and granzyme B specifically in response to mutant peptides compared with wild-type counterparts. TCR-transduced cells were detected in the peripheral blood of five patients, including the three responders, at levels ≥10% of CD3+ cells 1 month post-ACT. In one patient who responded to therapy, ~20% of CD3+ peripheral blood lymphocytes expressed transduced TCRs more than 2 years after treatment. This study provides early results suggesting that ACT with T cells genetically modified to express personalized neoantigen-reactive TCRs can be tolerated and can mediate tumor regression in patients with metastatic colorectal cancers.

[Epidemiological and etiological characteristics of herpes pharyngitis in 3 prefectures in Jiangsu Province].

Objective: To analyze the epidemiological and etiological characteristics of herpes pharyngitis (HA) in three prefectures of Jiangsu Province, and provide evidence for the prevention and control of HA in Jiangsu. Methods: Three surveillance sentinel hospitals in Wuxi, Suzhou and Yancheng were selected from May 2018 to December 2022, and information related to HA visits and hospitalized cases was regularly collected from the hospital inpatient management system by age groups. Enterovirus nucleic acid detection was performed by RT-PCR, and sequencing analysis, identification of genotype subtypes, and phylogenetic analysis were performed on the sequences of the gene encoding the coat protein VP1 of the main prevalent strains. Results: A total of 57 709 HA cases were recorded in the sentinel hospitals in in Wuxi, Suzhou and Yancheng, which was 1.76 times higher than the reported cases of hand, foot and mouth disease during the same period (57 709/32 831).The percentage of HA hospitalizations was 1.35% (781/57 709), and the percentage of hospitalizations showed an increasing trend from year to year (χ2=62.79, P<0.001 ).The incidence peak of HA was during May-July. The cases were mainly children aged 12-59 months (67.07%, 38 708/57 709), with the highest case number in age group 36-59 months (34.40%, 19 852/57 709). The HA positivity rate was 33.82% (644/1 904); enterovirus A was predominant (54.04%, 348/644); of these, Coxsackievirus (CV)A6 accounted for the highest percentage (52.59%, 183/348), while CVA16 and CVA4 accounted for 24.71% (86/348) and 15.23% (53/348), respectively. All 10 CVA4 HA endemic strains belonged to the C2 gene subtype, and all 6 CVA6 HA endemic strains belonged to the D3a gene subtype; and were genetically closer to and related to the strains in some areas of China (Fujian Province, Guangzhou City, Jiangxi Province, Yunnan Province, Tianjin City, etc.). Conclusions: The disease burden of HA was heavy in 3 areas in Jiangsu, children in age group 12-59-month were mainly affected, and the annual incidence peak of HA was during May-July. The pathogens causing HA varied, but predominated by enterovirus A and had low intra-typical differentiation, and no new evolutionary branches were found, suggesting that it is necessary to include HA in foot and mouth disease surveillance or regarded as a notifiable communicable disease.

Burden of gastrointestinal cancers among people younger than 50 years in China, 1990 to 2019.

OBJECTIVES: This study aimed to assess the burden of early-onset gastrointestinal (GI) cancers in China over three decades. STUDY DESIGN: A comprehensive analysis was performed using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. METHODS: Data on early-onset GI cancers in 2020 and from 1990 to 2019 were extracted from GLOBOCAN 2020 database and GBD 2019, respectively. The average annual percent change (AAPC) was calculated to analyze the temporal trends using the Joinpoint Regression Program. The Bayesian age-period-cohort (BAPC) model was used to predict future trends up to 2030. RESULTS: In China, there were 185,980 incident cases and 119,116 deaths of early-onset GI cancer in 2020, with the highest incidence and mortality observed in liver cancer (new cases: 71,662; deaths: 62,412). The spectrum of early-onset GI cancers in China has transitioned over the last 30 years. The age-standardized rates of incidence, mortality, and disability-adjusted life years for colorectal and pancreatic cancers exhibited rapid increases (AAPC >0, P ≤ 0.001). The fastest-growing incidence rate was found in colorectal cancer (AAPC: 3.06, P < 0.001). Despite the decreases in liver, gastric, and esophageal cancers, these trends have been reversed or flattened in recent years. High body mass index was found to be the fastest-growing risk factor for early-onset GI cancers (estimated annual percentage change: 2.75-4.19, P < 0.05). Projection analyses showed an increasing trend in age-standardized incidence rates for almost all early-onset GI cancers during 2020-2030. CONCLUSIONS: The transitioning pattern of early-onset GI cancers in China emphasizes the urgency of addressing this public health challenge.

[Analysis of pediatric heart transplantation supported by extracorporeal membrane oxygenation].

Objective: To summarize the clinical characteristics of patients with end-stage heart failure who receive heart transplant under extracorporeal membrane oxygenation (ECMO) support. Methods: The clinical data of 12 pediatric patients who received heart transplant with ECMO support in the Seventh Medical Center of Chinese People's Liberation Army General Hospital and Guangdong Provincial People's Hospital, from January 2019 to December 2023 was collected. The data included sex, age, weight, diagnosis, pre-ECMO lactate level, left ventricular ejection fraction (LVEF), vasoactive-inotropic score (VIS), and preoperative ECMO running time. Surgical data included cold ischemia time of the donor heart, cardiopulmonary bypass time, intraoperative use of immunosuppressant, postoperative use of ECMO, duration of postoperative ECMO, rate of successful weaning from ECMO, and survival discharge rate. The paired t-test was performed to compare cardiac function indices before and after left ventricular decompression. Results: The 12 patients ranged in age from 1.1 to 15.8 years, and weighted from 8 to 63 kg. Ten children were diagnosed with dilated cardiomyopathy, one with myocardial underdensification, and one with a novel heterozygous mutation of the SCN5A gene causing overlap syndrome complicated by fatal arrhythmia. Before ECMO, the lactate ranged from 0.6 to>15.0 mmol/L, the LVEF from 6.5% to 43%, and VIS from 3 to 108. Four patients underwent left ventricular decompression supported by preoperative ECMO, and their pulse pressure was significantly increased after decompression ((17.8±2.1) vs. (9.8±1.5) mmHg, 1 mmHg=0.133 kPa, t=11.31, P=0.001), while there was no apparent change in LVEF ((26.8±4.4)% vs. (24.9±4.9)%, t=1.75, P=0.178). A total of 7 children received a second run of ECMO after surgery and 3 of them successfully weaned off ECMO and survived to discharge. In the entire cohort, 10 were successfully weaned from ECMO and 8 survived to discharge. Conclusions: For children with end-stage heart failure supported by ECMO, left ventricular decompression can significantly improve pulse pressure. These patients will eventually require heart transplantation.

[Research progress on detection techniques for effective albumin concentration].

Hypoalbuminemia is one of the important clinical features of decompensated cirrhosis. As the disease progresses, not only does the total albumin concentration decrease, but so does the proportion of albumin that remains structurally and functionally intact. The structural and functional integrity of albumin is essential for its normal physiological role in the body. This led to the concept of "effective albumin concentration," which may be much lower than the total albumin concentration routinely measured clinically in patients with advanced cirrhosis. Liquid chromatography-tandem mass spectrometry, and electron paramagnetic resonance (EMR) are emerging technologies for effective albumin concentration detection, showing promising clinical application prospects, but research in patients with cirrhosis is still in the preliminary stage. Therefore, this article will comprehensively summarize the latest research on the aspects of effective albumin detection methods, liquid chromatography-tandem mass spectrometry, and electron paramagnetic resonance, as well as their applications.

[Epidemiological and clinical characteristics of respiratory syncytial virus infection among people aged 60 and above in Beijing City].

Objective: To investigate the epidemiological and clinical characteristics of RSV among patients aged ≥60 years in Beijing from 2015 to 2023. Methods: Based on the respiratory pathogen surveillance system, samples of upper respiratory tract infections (URTI), non-severe community-acquired pneumonia (nsCAP) and severe community-acquired pneumonia (sCAP) among people aged ≥60 years were collected from 28 sentinel hospitals in 16 districts of Beijing from January 2015 to December 2023. Swab samples were collected from URTI within one week, and lower respiratory tract samples from nsCAP and sCAP were collected. Demographic and epidemiological data were also collected. Various respiratory pathogens including RSV were detected. Results: From January 2015 to December 2023, a total of 20 349 cases of acute respiratory infections aged ≥60 years were included, with the RSV-positive rate of 1.54% (313/20 349, 95%CI: 1.39%-1.68%). Among them, the total RSV-positive rates of older people during the pre-pandemic, pandemic, and post-pandemic periods of COVID-19 were 1.59% (207/13 006, 95%CI: 1.38%-1.81%), 0.82% (38/4 650, 95%CI: 0.56%-1.08%) and 2.53% (68/2 693, 95%CI: 1.93%-3.12%), respectively. The difference in RSV-positive rate was statistically significant (P<0.001). Based on the sampling time of cases, the RSV epidemic season for older people in Beijing was from October to March of the following year, with a peak period in December or January of the following year. In the post COVID-19 pandemic, there were very few RSV-positive cases detected in the elderly from April to June 2023, with only one positive case detected in May and one in June. The RSV-positive rate of older people increased significantly from October to December, reaching 11.75% (51/383) in December. Among 263 RSV-positive cases in the elderly, RSV-A, RSV-B and unclassified type accounted for 43.35% (114/263), 29.28% (77/263) and 27.38% (72/263), respectively. Since 2020, there has been a subtype conversion, with RSV-B being the main focus. Among 197 elderly cases that have complete clinical data, the main symptoms were cough (86.8%, 171/197), sputum (80.2%, 158/197) and fever (73.60%, 145/197). About 24.87% (49/197) of elderly cases experienced complications. The hospitalization mortality rate was 4.57% (9/197), and the hospitalization rate was 78.68% (155/197). The ICU occupancy rate was 1.99% (36/197). The mechanical ventilation usage rate was 13.32% (33/197), and the length of hospital stay [M (Q1, Q3)] was 12 (9, 16) days. Conclusion: In Beijing, the RSV infection rate is relatively low during the COVID-19 pandemic, and the prevalence of COVID-19 is relatively high. In 2023, there was no out-of-season outbreak of RSV infection among the elderly. Elderly RSV infection cases have multiple complications, severe diseases, and poor prognosis.

[The association between visceral adipose thickness and gestational diabetes mellitus in the first trimester].

Objective: To investigate the association between visceral adipose tissue (VAT) thickness in early pregnancy and the risk of gestational diabetes mellitus (GDM). Methods: Based on the Qingdao Women and Children Health Cohort, pregnant women in the first trimester (11-13+6 weeks of gestation) were enrolled in this cohort study between May 2019 and October 2022. The VAT was measured in first trimester and determined as the distance from the inner margin of the rectus abdominis muscle to the anterior wall of the great artery using multi-functional color ultrasound. The 75 g oral glucose tolerance test (OGTT) results were followed up at 24-28 weeks and the participants were divided into GDM group and non-GDM group. The pregnant women were divided into 4 groups according to the VAT quartile. Log-binomial model and linear regression model were used to analyze the association between VAT and GDM/blood glucose. Results: A total of 3 686 pregnant women were included in this study, the mean age of participants was (30.56±4.05) years and 722 were diagnosed with GDM, with an incidence of 19.6%. The log-binomial regression model results showed that compared with VAT thickness Q1 (VAT<14.70 mm), the GDM risk in Q3 (21.65≤VAT≤29.69 mm) and Q4 (VAT ≥29.70 mm) increased by 34% [RR(95%CI): 1.34 (1.08-1.67)], and 61% [RR(95%CI): 1.61 (1.30-2.00)], respectively. Among women with gestational age<35 years old, compared with VAT thickness Q1, the risk of GDM increased by 42% in Q3 [RR(95%CI): 1.42 (1.22-1.65)] and 70% [RR(95%CI): 1.70 (1.46-1.98)] in Q4, whereas no associations were found in women with gestational age ≥35 years old (P>0.05). The association between VAT and GDM risk was only found in pregnant women with pre-pregnancy BMI <24.0 kg/m2, and the GDM risk increased by 57% [RR(95%CI): 1.57 (1.22-2.04)] in Q3 and 65% [RR(95%CI): 1.65 (1.24-2.19)] in Q4 compare with Q1. The results of multiple linear regression analysis showed that VAT was positively correlated with fasting blood glucose, 1-hour blood glucose after 75 g OGTT and 2-hours blood glucose after 75 g OGTT (all Pfor trend<0.001). Conclusion: High VAT thickness in early pregnancy is an independent risk factor for GDM, and the GDM risk increases with the raising of VAT depth.

The impact of the host microbiota on Candida albicans infection.

The human microbiota is a complex microbial ecosystem populated by bacteria, fungi, viruses, protists, and archaea. The coexistence of fungi alongside with many billions of bacteria, especially in the gut, involves complex interactions, ranging from antagonistic to beneficial, between the members of these two kingdoms. Bacteria can impact fungi through various means, such as physical interactions, secretion of metabolites, or alteration of the host immune response, thereby affecting fungal growth and virulence. This review summarizes recent progress in this field, delving into the latest understandings of bacterial-fungal-immune interactions and innovative therapeutic approaches addressing the challenges of treating fungal infections associated with microbiota imbalances.

[Circ_0000263 improves radiosensitivity of Hela cells by inhibiting the activity of telomerase protein through miR-338-3p/TERT].

Objective: To explore the effect and molecular mechanism of circ_0000263 on HeLa cell activity, apoptosis, telomerase activity, and radiosensitivity. Methods: The Hela cells were divided into si-NC, si-circ, vector, circ_0000263, anti-NC, anti-miR-338-3p, miR-NC, miR-338-3p, si-circ+anti-NC, si-circ+ anti-miR-338-3p, si-circ+vector, si-circ+TERT, sh-NC, sh-circ groups. Reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) was used to detect the expressions of circ_0000263 and miR-338-3p. Cell clone formation array was used to detect cell survival; cell counting kit-8 (CCK-8) to detect cell proliferation; flow cytometry to detect apoptosis; western blot method to detect the expressions of proliferating cell nuclear antigen (PCNA), Cleaved-casp3, telomerase reverse transcriptase (TERT) proteins; double luciferase assay to detect the targeting relationships of circ_0000263 and miR-338-3p, miR-338-3p and TERT; telomere repeat amplification enzyme linked immunosorbent assay (TRAR-ELISA) to detect telomerase activity. Results: Circ_0000263 was highly expressed in Hela cells, miR-338-3p was low expressed, and TERT was highly expressed; circ_0000263 was also highly expressed in Hela cells treated with radiation (P＜0.05). Knockdown of circ_0000263 inhibited the clone formation and cell proliferation ability of HeLa cells, and enhanced the radiosensitivity and apoptosis of HeLa cells. In contrast, knockdown of circ_0000263 decreased PCNA protein expression level and enhanced Cleaved-casp3 protein expression level in HeLa cells (P＜0.05). The apoptosis rate in the si-circ group was (13.19±1.12)%, which was higher than (6.80±0.62)% of si-NC group (P＜0.05). The apoptosis rate in the si-circ+4 Gy group was (24.82±1.57)%, which was higher than (17.00±0.96)% of si-NC+4 Gy group (P＜0.05). Circ_0000263 targeted regulated miR-338-3p, and miR-338-3p targeted regulated TERT. MiR-338-3p was lowly expressed in HeLa cells, and knockdown of circ_0000263 elevated miR-338-3p expression level in HeLa cells. Circ_0000263 regulated TERT expression and inhibited telomerase activity through miR-338-3p. MiR-338-3p/TERT can restore the effect of circ_0000263 on the radiosensitivity of Hela cells. The apoptosis rate in the si-circ+anti-NC group was (27.37±0.89)%, which was higher than (18.22±1.18)% of the si-circ+anti-miR-338-3p group (P＜0.05). The apoptosis rate in the si-circ+vector group was (27.55±0.48)%, which was higher than (20.10±0.68)% of si-circ+TERT group (P＜0.05). After 72 hours of radiation by 4 Gy, the cell survival fraction of si-circ+anti-NC group was 0.41±0.02, which was lower than 0.66±0.03 of the si-circ+anti-miR-338-3p group (P＜0.05); the cell survival fraction of si-circ+vector group was 0.42±0.05, which was lower than 0.70±0.03 of si-circ+TERT group (P＜0.05). Conclusion: Inhibiting the expression of circ_0000263 supresses the proliferation of Hela cells by regulating miR-338-3p/TERT, promotes apoptosis, inhibits telomerase activity, increases the radiosensitivity of cancer cells, and provides a theoretical basis for improving the radiosensitivity of Hela cells.
