Objective:To investigate the relationship between dynamic alterations in serum albumin (ALB) concentrations and clinical outcomes in hospitalized surgical patients, thus providing a basis for optimizing clinical management strategies.Methods:This study utilized data from a prospective observational cohort study on nutritional status among 7 122 elderly hospitalized patients across 34 tertiary hospitals in 18 Chinese cities. A total of 1 714 surgical patients hospitalized for 7-30 days with complete data were included. Standardized protocols were used to collect demographic data, clinical outcomes, and a range of laboratory results, including nutritional and hematological parameters. Heterogeneous effects of ALB on clinical outcomes were explored. Receiver operating characteristic (ROC) curves were used to determine cutoff values for infection-related complications. Correlation analyses and multiple linear regression models were used to identify independent predictors of the absolute change in ALB (?ALB).Results:Among the surgical patients, 69.7% (1 195/1 714) experienced a decline in ALB levels during their hospital stay, which was significantly associated with the occurrence of both infection- and non-infection-related complications. Simultaneously, a marked decrease in ALB was also significantly correlated with changes in nutritional and inflammatory status during hospitalization, worsening of gastrointestinal symptoms at discharge, and functional activity abnormalities (all P<0.05). ?ALB exhibited a close association with outcome variables such as infection-related complications. Based on the incidence of infection-related complications, a cutoff value for ALB was calculated, dividing patients into a high-risk group ( n=179) and a low-risk group ( n=1 535), and a statistically significant difference in the incidence of infection-related complications was found between these two groups ( P<0.05). Correlation analysis and multiple linear regression modeling revealed that female gender, a higher baseline ALB level, a poorer baseline inflammatory status, an exacerbation of inflammatory status, larger alterations in platelet-to-lymphocyte ratio, and the presence of infection-related complications were predictive factors for a decline in ALB levels among surgical patients during their hospital stay. Conclusions:?ALB serves as a critical indicator of the inflammatory-nutritional interplay, with its magnitude of decline effectively predicting clinical outcomes and nutritional status changes and guiding multidisciplinary interventions in surgical patients.

OBJECTIVE To observe the detection and drug resistance of carbapenem-resistant Klebsiella pneumoni-ae(CRKP)strains causing hospital-acquired infections(HAI)and community-acquired infections(CAI)in recent years so as to provide bases for prevention and control of CRKP infection and reasonable clinical use of antibiotics.METHODS A total of 3444 patients who were diagnosed with Klebsiella pneumonia infection and were hospitalized in the 2nd Affiliated Hospital of Fujian Medical University from Jan.1,2017 to Dec.31,2023 were recruited as the research subjects.Totally 230 patients with CRKP infection were chosen based on the result of drug susceptibility testing,73 of whom had HAI,and 157 had CAI.The isolation rate of CRKP strains,popula-tion distribution,specimens sources and drug resistance rates were observed and compared between the patients with HAI and the patients with CAI.RESULTS The total isolation rate of CRKP strains was 6.68％(230/3444).There was no difference in the sex of the patients with CRKP infection between the HAI patients and the CAI patients,however,the isolation rate of the CRKP strains from the patients aged between 18 and 45 years old was higher in the HAI group than in the CAI group(P＜0.05).The isolation rates of CRKP strains causing the two types of infections increased year by year,showing a remarkable increasing amplitude in 2022-2023,with the HAI increasing from 9.33％to 20.67％,the CAI increasing from 5.54％to 15.03％.The lower respiratory tract,urinary tract and bacteremia were the most common infection sites,the detection rate of soft tissue infec-tions was higher among the patients with HAI than among the patients with CAI(P=0.047).CRKP strains cau-sing HAI showed the highest isolation rate(33.33％)in catheter specimens,and the isolation rate of CRKP strains in pus specimens was higher among the HAI patients than among the CAI patients(P=0.011).The isola-tion rate of CRKP strains in sputum specimens of the CAI patients raised four times in 2023 as compared with that in 2022.The drug resistance rates of the CRKP strains to 25 types of antibiotics were relatively high and showed upward trends;the drug resistance rate of the HAI-KPN strains to imipenem was 48.78％,higher than 7.09％of the CAI-KPN strains(P＜0.001),and there were no significant differences in the drug resistance rates to other carbapenems between the CAI-KPN strains and the HAI-KPN strains.CONCLUSIONS The isolation rates of the CRKP strains causing the HAI and CAI are increasing year by year.The clinical invasive procedures and community-acquired respiratory tract infections are the key points for prevention and control.It is necessary to in-tensify the hospital-community cooperative prevention and control system based on the isolation rates and drug re-sistance rates of the CRKP strains,and take comprehensive prevention and control measures so as to curb the transmission of the drug-resistant strains.

The new cultural construction of high-quality development of public hospitals proposes a patient-oriented ap-proach.People with disabilities,represented by the hearing-impaired community,faces many difficulties in the process of seeking medical care,and their needs have not been adequately addressed.This inadequacy adversely affects the development of harmoni-ous doctor-patient relationships and the patient medical experience.This study takes the deaf assistance outpatient clinic,first es-tablished by Shanghai East Hospital as an example to elaborate the practice of cultural brand construction under the leadership of Party building.Medical social workers,healthcare professionals,and volunteers work together to build a cultural brand through institutional guarantees,detailed care,and the establishment of a full process service system.This is expected to provide refer-ences for the construction of hospital cultural brands..

Neurogenic bladder(NB)is one of the most challenging urinary system disorders,with spinal cord injury(SCI)being an important etiological factor.Animal models provide crucial tools for investigating the pathogenesis,therapeutic strategies,and novel drug screening for NB subsequent to SCI.We reviewed and synthesized recent literature on NB animal models after SCI from both domestic and international sources.This review summarizes and analyzes research advancements using these models in terms of animal species,SCI segments,modeling techniques,and evaluation indicators,with the aim of offering insights and guidance for future experimental research based on animal models of NB following SCI.

Objective:To investigate potential factors associated with nephrocalcinosis in children with X-linked hypophosphatemic rickets (XLH).Methods:A case-control study was conducted involving XLH children who were regularly followed up at Children′s Hospital of Nanjing Medical University, from January 2016 to January 2024.Patients diagnosed with nephrocalcinosis were assigned to the case group, and those without nephrocalcinosis served as controls.A retrospective analysis was performed to examine the correlation between nephrocalcinosis and laboratory parameters, as well as the diagnostic value of relevant factors.Multivariable Logistic regression was used to identify factors associated with nephrocalcinosis in children with XLH.Receiver operating characteristic (ROC) curves were plotted for the significant factors, and the areas under the curve (AUC) were compared using Delong′s test to evaluate differences in predictive performance.Results:Univariate analysis revealed significant differences between the case and control groups in serum calcium, urinary calcium, urinary calcium/creatinine ratio, urinary phosphorus, and renal tubular maximum reabsorption rate of phosphate/glomerular filtration rate (TmPi/GFR) (all P<0.05).However, multivariate logistic regression analysis identified only urinary calcium ( B=0.489, P=0.001) and TmPi/GFR ( B=-0.886, P=0.007) as independent predictors, while the urinary calcium/creatinine ratio was not statistically significant.The sensitivity, specificity, optimal cutoff value, and AUC for urinary calcium in predicting nephrocalcinosis were 0.842, 0.833, 0.614 mmol/L, and 0.851 ( P<0.01), respectively.For TmPi/GFR, the corresponding values were 0.900, 0.877, 0.573 mmol/L, and 0.875 ( P<0.01).The Delong test showed no significant difference in AUC between the combined indicator and TmPi/GFR ( Z=-1.555, P=0.120) or urinary calcium alone ( Z=-1.598, P=0.110). Conclusions:Urinary calcium and TmPi/GFR are significantly associated with nephrocalcinosis in children with XLH and demonstrate good predictive performance for early detection.The combination of these two indicators does not outperform either individual marker in diagnostic accuracy.

OBJECTIVE: To investigate the clinical phenotypic and genetic characteristics of three children with Paroxysmal kinesigenic dyskinesia (PKD) and Self-limited familial infantile epilepsy (SeLIE) caused by PRRT2 gene mutation. METHODS: Three children with PKD and SeLIE caused by PRRT2 gene mutation (children 1-3) who were treated in the First Affiliated Hospital of Zhengzhou University from November 2022 to August 2023 were selected as the research subjects. A retrospective study was conducted to collect the clinical and family history data of the three children. 2 mL of peripheral venous blood from children 1-3 and parents of children 1-2 were collected (parents of children refused to undergo genetic testing and no blood samples were collected), genomic DNA was extracted, whole exome sequencing (WES) was performed, and Sanger sequencing method was used for verification. According to the Classification Standards and Guidelines for Genetic Variants formulated by the American Society of Medical Genetics and Genomics (ACMG) (hereinafter referred to as the "ACMG Guidelines"), the pathogenicity of the variant loci detected in three children was rated, and the detrimental loci of the variant loci were analyzed by multiple bioinformatics software. This study has been approved by the Ethics Committee of the First Affiliated Hospital of Zhengzhou University (Ethics No. 2024-KY-0881-002). RESULTS: The clinical data and genetic test results of the three children in this study are as follows. Child 1: female, age of onset of 4 months and 10 days, with seizures, manifested as sudden cessation of movements, staring in both eyes, cyanosis of the lips, paleness, and stiffness and shaking of limbs. The results of genetic testing showed that child 1 had maternal PRRT2 gene c.583_584dup (p.P196Afs*34) frameshift variant, which was rated as a pathogenic variant (PVS1 PM2_Supporting PP4) according to ACMG guidelines. According to the clinical manifestations and genetic test results of child 1, he was diagnosed with SeLIE and took oral sodium valproate [0.5 mL/(kg.d)], and was still taking medication at the follow-up of 2 years old, and did not have seizures again after 5 months of age. Child 2: male, age of onset of 10 years old, manifested as dystonia after sudden movement. The results of genetic testing showed that child 2 had PRRT2 gene mutations: paternal c.649dupC (p.R217Pfs*8) frameshift variant and maternal c.445C>A (p.Q149K) mutation. Among them, c.649dupC was a reported pathogenic variant, and according to ACMG guidelines, c.445C>A variant was rated as a variant of unknown clinical significance (PM2_Supporting), with a high probability of benignness. According to the clinical manifestations and genetic test results of the child 2, he was diagnosed with PKD, and was followed up with oral oxcarbazepine 9 mg/(kg.d) until 12 years and 2 months, and was still on the drug, and there was no recurrence of the seizure of the form of dyskinesia after taking the drug. Child 3: male, age of onset of 11 years old, manifested by dystonia after sudden exercise. The results of genetic testing showed that child 3 had a missense variant of PRRT2 gene c.904G>C (p.D302H), and his parents refused genetic testing, and the source of the mutation was unknown, and the variant was rated as a variant of unknown clinical significance (PM2_Supporting+PP3_Moderate+PP4) according to ACMG guidelines. According to the clinical manifestations and genetic test results of child 3, he was diagnosed with PKD, and was treated with oral oxcarbazepine 10 mg/(kg.d) for 1 year and then discontinued on his own, and was followed up at the age of 17, and there was no recurrence of the seizure of the form of movement disorder after taking the drug. CONCLUSION One case of SeLIE and two cases of PKD caused by PRRT2 gene mutations responded well to anti-seizure drugs. In this study, four variant loci of PRRT2 gene were found: c.583_584dup, c.904G>C, c.649dupC, c.445C>A, among which c.583_584dup were new variants, enriching the variant spectrum of PRRT2 gene.

OBJECTIVE: To analyze the clinical characteristics and genetic etiology of a child with Christianson syndrome (CS). METHODS: A 1-year-and-5-month-old boy with CS diagnosed at the First Affiliated Hospital of Zhengzhou University in April 2021 was selected as the study subject. Clinical data were retrospectively analyzed. Peripheral blood samples were obtained from the child and his parents, followed by genomic DNA extraction and whole exome sequencing (WES). Candidate variant was validated by Sanger sequencing. This study has been approved by the Medical Ethics Committee of the Hospital of Zhengzhou University (Ethics No. 2024-KY-1103-001). RESULTS: The child has manifested with seizures, microcephaly, and global developmental delay. WES revealed that he has harbored a novel de novo hemizygous nonsense variant of the SLC9A6 gene, namely c.1014G>A (p.W338*). Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic. CONCLUSION The hemizygous c.1014G>A nonsense variant of the SLC9A6 gene probably underlay the pathogenesis in this child. Above discovery has expanded mutational spectrum of the SLC9A6 gene and enabled definite diagnosis of the child.
