With the rapid development of mobile internet technology, mobile health application (mHealth APP) are increasingly widely used in the field of health management and have been proven to play an important role in the management of chronic diseases. Solid organ transplant recipients face complex health management needs after surgery, including postoperative follow-up, medication management, prevention and treatment of complications and comorbidities, and lifestyle adjustment. mHealth APP can provide solid organ transplant recipients with convenient self-management tools. Although some progress has been made in this field, there are still many challenges, such as insufficient user experience, technological dependence, and data security risks. Therefore, this article discusses the development process, main functions and current application status of mHealth APP, and analyzes its advantages in improving the self-management ability of solid organ transplant recipients, promoting doctor-patient communication and reducing the incidence of complications. At the same time, based on the practical experience of author’s team in developing the “TransMate” mHealth APP, we propose the directions that mHealth APPs should focus on in the future, in order to provide more effective support and services for the health management of solid organ transplant recipients.

AIM:To investigate the influencing factors of dry eye in elderly people aged over 60 years, and to construct a risk nomogram prediction model, so as to provide a reference for the identification of high-risk individuals and the development of preventive strategies.METHODS:A convenience sampling method was used to select 301 people aged over 60 years who attended the ophthalmology outpatient clinic or were hospitalized at the Second Affiliated Hospital of Guangzhou Medical University between July 2023 and December 2023. They were divided into a dry eye group(n=173)and a non-dry eye group(n=128)based on the presence or absence of dry eye. Data from the two groups were compared and a risk prediction model was constructed.RESULTS:Gender, hypertension, meibomian gland dysfunction, frequent use of eye drops, frequent use of electronic products, and frequent exposure to dry environments were significant influencing factors for the occurrence of dry eye in people aged over 60 years(all P<0.05). The nomogram prediction model demonstrated excellent discrimination(AUC=0.86, 95% CI: 0.81-0.90). The calibration curve showed good fit with the ideal curve, indicating high predictive accuracy. The Hosmer-Lemeshow test yielded a P-value of 0.424. The sensitivity was 73% and the specificity was 86%.CONCLUSION:The nomogram predictive model for the risk of dry eye in elderly people aged over 60 years constructed in this study showed good discrimination and calibration. It can serve as an intuitive and effective clinical risk assessment tool, providing a basis for the early identification of high-risk populations and the development of individualized intervention strategies.

Objective To compare the clinical efficacy of abdominal ultrasound-guided endoscopic retrograde appendicitis therapy(ERAT)with laparoscopic appendectomy(LA)for acute uncomplicated appendicitis using propensity score matching.Methods The clinical data of 441 patients with acute uncomplicated appendicitis admitted to the Third People's Hospital of Yunnan Province from March 2020 to April 2023 were collected.The cases were classified based on the differences in surgical method and divided into the ERAT group(n = 30)and LA group(n = 411).The clinical efficacy of patients was compared between the two groups after reducing confounding bias by propensity score matching(PSM).Results After PSM,a total of 30 pairs of patients in the two groups were successfully matched,and the baseline data of the two groups met the requirements for comparability.At 24 hours after the operation,the ERAT group exhibited lower white blood cells,neutrophil counts,and C-reactive protein levels compared to the LA group,and these differences were statistically significant(P<0.05).There was no significant difference in the operation time and total effective rate between the ERAT group and the LA group(P>0.05).However,the ERAT group had lower intraoperative blood loss and shorter pain relief time compared to the LA group,and these differences were statistically significant(P<0.05).Conclusion Abdominal ultrasound-guided endoscopic retrograde appendicitis treatment is an effective,safe,and feasible technique with good prospects for the treatment of acute uncomplicated appendicitis.

Objective To explore the application efficacy and safety of oblique ultrasound-guided techniques in PICC puncture,in order to provide guidance and references for clinical application.Methods Through convenient sampling,654 patients from a tertiary A hospital in Zhejiang Province from March to December 2022 were selected as the study subjects.The random numbers were generated through Excel table functions and they were randomly grouped into 3 groups:A,B,and C.The ultrasound short axis method,long axis method,and oblique axis method were employed to guide PICC puncture catheterization,respectively.The success rate of PICC puncture,the number of subcutaneous adjustments of the puncture needle,puncture time,and the occurrence of puncture complications(such as hematoma,puncture of the posterior wall of blood vessels,accidental injury to arteries,and accidental injury to nerves)were recorded during the catheterization process in 3 groups.Results A total of 654 patients completed the study,including 215 in group A,219 in group B,and 220 in group C.The success rate of first-time puncture in the group C(86.36％)was higher than that in group A(73.95％)and group B(63.93％),and there was a statistically significant difference among 3 groups(P＜0.001).The subcutaneous adjustment frequency of the puncture needle was 1(1,1)in group C,1(1,2)in group A,and 1(1,2)in group B.The difference between 3 groups was statistically significant(P＜0.001);the puncture time of group C was shorter than that of group A and group B,and the difference was statistically significant(P＜0.001).There was a statistically significant difference in the puncture time between 3 groups(P＜0.017);the pairwise comparison of the number of subcutaneous needle adjustments and the success rate of a puncture between 3 groups showed that there was a statistical difference between group C and group A,and between group C and group B(P＜0.017),while there was no statistical difference between group A and group B(P＞0.017).There was statistical significance(P＜0.05)among 3 groups in terms of complications such as accidental nerve injury and puncture of the contralateral vascular wall by puncture needle,but there was no statistical significance in terms of accidental arterial injury and hematoma occurrence among 3 groups.Conclusion Compared with the short axis approach and the long axis approach,the ultrasound oblique axis approach guided PICC puncture has statistical differences in the success rate of a puncture and the incidence of puncture complications,etc.It is recommended to use the ultrasound oblique axis approach during PICC puncture.

Objective To study adverse drug events(ADEs)of busulfan the U.S.Food and Drug Administration Adverse Event Reporting System(FAERS),and to mine the potential ADE signals,so as to provide reference for the safe drug use in clinical practice.Methods Data from the first quarter of 2004 to the first quarter of 2023 were retrieved from the FAERS database,and ADE records for busulfan as a primary suspect drug were obtained through data cleaning and standardization of target drug names.Risk signals for busulfan ADEs were mined based on the reporting odds ratio method,the proportional reporting ratio method,and Medicines and Healthcare Products Regulatory Agency method.The information component method was used to assess the intense of the risk signals.The ADEs were systematically classified according to Medical Dictionary for Regulatory Activities(MedDRA),and two ranking sequence of busulfan ADEs were generated by signal occurrence frequency and signal intense,respectively.Results A total of 20 326 ADE records were collected,involving 5 615 patients with 556 related ADE signals,of which 117 were newly reported as compared to those in the drug instruction of busulfan.Male patients accounted for a higher proportion than female patients(40.71％vs.30.74％).The main population of patients were younger than 18 years old(31.56％).The reports were most reported by physicians(33.71％)and other health professionals(24.35％)as well as pharmacists(23.86％),mainly from the United States(29.69％),Japan(15.78％),and France(11.79％).The top five ADEs in terms of occurrence frequency were busulfan use in unapproved indications,hepatic veno-occlusive disease(HVOD),mucosal inflammation,cytomegalovirus infection,and graft versus host disease.The top five ADEs in terms of signal intense were HVOD,acute graft versus host disease,veno-occlusive disease,graft versus host disease,and chronic graft versus host disease.The ADE signals involves 23 system organ classes.The top three SOCs in terms of the number of ADE signals were infections/infestations,investigations and neoplasms benign/malignant/unspecified(include cysts and polyps).Conclusion When busulfan is used in clinic,attention should be paid to its adverse events in hepatic veno-occlusive disease,infections,graft versus host disease,neurotoxicity,and venous thromboembolism,which are likely to cause serious consequences.The clinical pharmacists can assist clinicians to make prevention plans in case of busulfan ADEs,so as to improve the safety of busulfan use in clinic.

Objective To examine the precise function of influenza A virus target genes(IATGs)in malignancy. Methods Using multi-omics data from the TCGA and TCPA datasets,33 tumor types were evaluated for IATGs.IATG expression in cancer cells was analyzed using transcriptome analysis.Copy number variation(CNV)was assessed using GISTICS 2.0.Spearman's analysis was used to correlate mRNA expression with methylation levels.GSEA was used for the enrichment analysis.Pearson's correlation analysis was used to examine the association between IATG mRNA expression and IC50.The ImmuCellAI algorithm was used to calculate the infiltration scores of 24 immune cell types. Results In 13 solid tumors,IATG mRNA levels were atypically expressed.Except for UCS,UVM,KICH,PCPG,THCA,CHOL,LAMI,and MESO,most cancers contained somatic IATG mutations.The main types of CNVs in IATGs are heterozygous amplifications and deletions.In most tumors,IATG mRNA expression is adversely associated with methylation.RT-PCR demonstrated that EGFR,ANXA5,CACNA1C,CD209,UVRAG were upregulated and CLEC4M was downregulated in KIRC cell lines,consistent with the TCGA and GTEx data. Conclusion Genomic changes and clinical characteristics of IATGs were identified,which may offer fresh perspectives linking the influenza A virus to cancer.

Objective:To examine the burden and trends of acute viral hepatitis in Guangdong Province from 1990 to 2019, and provide reference evidences for hepatitis prevention and control in the province.Methods:Data on acute viral hepatitis (hepatitis A, B, C, and E) in Guangdong from 1990 to 2019 were extracted from the Global Burden of Disease Study 2019 database. The incidence, prevalence, mortality, and disability-adjusted life years (DALY) data were analyzed by age and gender, and the estimated annual percentage change (EAPC) was calculated to describe the changing trends in disease burden.Results:From 1999 to 2019, the standardized incidence, prevalence, mortality, and DALY of acute viral hepatitis in Guangdong were higher than the national averages. In 2019, 51.43% (2 245 087/4 365 221) of acute viral hepatitis cases in Guangdong Province were mainly attributed to hepatitis B, and 77.18% (106/138) of deaths were due to acute hepatitis B. In different age groups, except for acute hepatitis B, which was more common in adults, the incidence rates of other types of viral hepatitis such as hepatitis A, B, and E showed an overall decreasing trend with age. The mortality rates of different types of acute viral hepatitis, except for the <5 age group, increased with age. The overall incidence and mortality rates of acute viral hepatitis were higher in men than in women.Conclusions:The overall burden of acute viral hepatitis in Guangdong declined in 2019, but remained higher than the national level. Further efforts are needed to strengthen hepatitis prevention and screening in different population in Guangdong Province, especially in children and the elderly.

Objective To investigate the current status,obstacles,and specific needs associated with the application of transradial access(TRA)in peripheral interventions in Chinese hospitals,with the aim of promoting the broader adoption of TRA in interventional procedures.Methods The Committee of Interventional Oncology of China Anti-Cancer Association conducted a cross-sectional questionnaire survey to investigate and analyze the nationwide situation of TRA in peripheral interventional surgeries in 2022.Results Personnel from 60 hospitals participated in the questionnaire.The results showed that the number of peripheral interventionals performed using TRA was significantly lower than that performed using transfemoral access(TFA),with considerable variability among hospitals.The primary obstacles to the adoption of TRA were the lack of suitable catheters and the difficulty of radial artery puncture.Approximately 86.67％of the institutions expressed a high expectation for the innovation of new TRA-specific devices,particularly catheters,microcatheters,and guidewires.60.00％of medical institutions indicated a strong desire for systematic training and participation in multi-center clinical trials.Conclusions TRA peripheral intervention is feasible in many hospitals in China,however,systematic training and further promotion of TRA are essential.The innovation of new TRA-specific devices and TRA in peripheral intervention is urgent.

Objective To explore the value of model established with radiomics features based on contrast enhanced arterial phase CT and model with radiogenomics for predicting prognosis of ovarian serous cystadenocarcinoma(OSC).Methods Enhanced arterial phase CT images of 110 OSC patients were retrospectively collected from 2 centers and The Cancer Imaging Archive(TCIA)database.The radiomics features were extracted,among those related to prognosis were selected to establish a radiomics Cox regression model.Genes data of 399 OSC patients were obtained from The Cancer Genome Atlas(TCGA)database,and genes related to the radiomics features included in the above radiomics model were identified with high Pearson correlation coefficient,and then enrichment gene analyses were performed.For 57 OSC cases with complete enhanced CT and gene data,the hub genes which had the highest connectivity with radiomics prognosis predicting model were detected using Cox regression and protein-protein interaction(PPI).Furthermore,a radiogenomics prognosis predicting model was established with the hub genes.The efficiencies of these 2 models for predicting prognosis of OSC patients were analyzed.Results Finally,the radiomics model included 5 OSC prognosis-related radiomics features,with C-index of 0.782 and 0.735 in corresponding training and test set,respectively.Meanwhile,the radiogenomics model included 30 prognostic hub genes,with C-index of 0.673 and 0.659 in corresponding training and test set,respectively.The survival rates of patients with better predicted prognosis according to radiomics model and radiogenomics model were both higher compared with the others(both P＜0.05).Totally 1 135 mRNA genes were found being associated with radiomics model,including biological behaviors such as cell adhesion,and signaling pathways such as PI3K-Akt,extracellular matrix receptor interaction pathway and type 1 diabetes pathway.Conclusion The radiomics model was effective for predicting prognosis of OSC patients.Analysis of mRNA bioinformatics in OSC patients might provide biological interpretations for the radiomics model.
