Objective:To assess the clinical features and effectiveness of antiviral therapy in newborns with sensorineural hearing loss (SNHL) caused by congenital congenital cytomegalovirus (cCMV) infection, and to speculate the risk factors for poor hearing outcomes.Methods:A multicenter prospective cohort study wasconducted, enrolling 176 newborns diagnosed with cCMV at four research centers in Zhejiang Province from March 1, 2021, to April 30, 2024. Clinical characteristics at birth were recorded and hearing was followed up. The children were divided into groups based on their condition at birth, specifically into asymptomatic, mild symptom, and moderate to severe symptom groups. Additionally, they were divided into SNHL and normal hearing groups based on the results of air conduction brainstem audiometry at birth. And they were also divided into treatment and untreated groups according to antiviral treatment. Mann Whitney U test, and chi square test were used for inter group comparison to analyze the differences in clinical features between different disease groups, and to analyze the effects of clinical features, antiviral therapy, and other factors on hearing improvement. Logistic regression analysis was employed to identify the risk factors influencing hearing outcomes. Results:Among the cohort of 176 children diagnosed infection with cCMV, 90 cases were male and 86 cases were female. Of these, 79 cases were asymptomatic, 12 cases classified as mild cCMV and 85 cases as moderate to severe cCMV. Fifty cases belonged to SNHL group, with different degrees of severity, including 30 cases of mild, 9 cases of moderate, 5 cases of severe, and 6 cases of extremely severe SNHL. Among the 121 cases in the normal hearing group, 2 cases (1.7%) exhibited late-onset hearing loss despite having normal hearing at birth. Among 81 cases (46.0%) who completed the hearing follow-up, 71 cases (87.7%) had good hearing outcomes and 10 cases (12.3%) had poor hearing outcomes. Among the 81 children, 29 cases (35.8%) had SNHL at birth. During follow-up, the hearing threshold improved in 19 cases (65.5%), remained stable in 7 cases (24.1%) and progressed in 3 cases (10.3%). A total of 26 cases in the treatment group and 55 cases in the untreated group completed the hearing follow-up assessment. The rate of hearing improvement in the treatment group was found to be higher compared to the untreated group (13 cases (50.0%) vs. 6 cases (10.9%), χ2=15.00, P<0.01), with individuals in the treatment group having a 4.58 times greater likelihood of experiencing hearing improvement ( RR=4.58,95% CI 1.96-10.70, P<0.05). However, no statistically significant difference was observed in hearing outcomes between the antiviral treatment group and the untreated group ( RR=0.90, 95% CI 0.57-1.41, P=0.517). Multivariate analysis further confirmed SNHL ( OR=11.58, 95% CI 2.10-63.93, P=0.005) and preterm birth ( OR=4.98, 95% CI 1.06-23.41, P=0.042) as independent risk factors for poor hearing outcomes. Conclusions:SNHL resulting from cCMV infection presents symptoms at birth and can be improved by antiviral therapy. Poor hearing outcomes are associated with SNHL and prematurity.

Recent advancement in natural language processing (NLP) and medical imaging empowers the wide applicability of deep learning models. These developments have increased not only data understanding, but also knowledge of state-of-the-art architectures and their real-world potentials. Medical imaging researchers have recognized the limitations of only targeting images, as well as the importance of integrating multimodal inputs into medical image analysis. The lack of comprehensive surveys of the current literature, however, impedes the progress of this domain. Existing research perspectives, as well as the architectures, tasks, datasets, and performance measures examined in the present literature, are reviewed in this work, and we also provide a brief description of possible future directions in the field, aiming to provide researchers and healthcare professionals with a detailed summary of existing academic research and to provide rational insights to facilitate future research.

OBJECTIVETo identify the predictive factors for differentiating pancreatic ductal adenocarcinoma (PDAC) from other neoplastic solid pancreatic lesions and assess the accuracy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for diagnosis of PDAC.

METHODSWe retrospectively analyzed the clinical data of patients referred for EUS-FNA evaluation of pancreatic lesions in the Digestive Endoscopic Center of Nanfang Hospital between January, 2009 and May, 2016. The cases with unknown diagnosis, missing data, repeated punctures, cystic lesions and benign lesions were excluded from the analysis. The positivity rates of EUS-FNA were compared between patients with PDAC and those with non-PDAC lesions, and the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of EUS-FNA were assessed in the diagnosis of PDAC. Univariate and multivariate logistic regression analyses were used to identify the factors for differentiating PDAC from non-PDAC lesions based on the demographic characteristics, clinical presentations, laboratory data, and endoscopic ultrasonography imaging features of the patients.

RESULTSAmong the 75 patients with solid neoplastic pancreatic lesions, 54 (72.0%) were found to have PDAC and 21 (28.0%) had non-PDAC lesions. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EUS-FNA for the diagnosis of PDAC were 77.8%, 100.0%, 100.0%, 63.6% and 84.0%, respectively. No significant difference was found in the positivity rate of EUS-FNA between patients with PDAC and those with non-PDAC lesions (77.8% 76.2%, > 0.05). Multivariate regression analysis identified abdominal pain (=5.163, 95%: 1.093-24.389, =0.038), lesion size (=0.926, 95%: 0.877-0.978, =0.006), characteristics of the solid lesions (=7.105, 95%: 1.440-35.043, =0.016), and evidence of metastases (=6.165, 95%: 1.332-28.533, =0.020) as the independent factors for predicting PDAC.

CONCLUSIONSThe pretest characteristics including abdominal pain, evidence of metastases, and lesion size and lesion characteristics defined by endoscopic ultrasonography findings can reliably predict a diagnosis of PDAC. EUS-FNA has a high sensitivity and a high specificity for the diagnosis of PDAC.

Objective To investigate the diagnostic value of endoscopic ultrasound-guided fine needle aspiration ( EUS-FNA) on malignant lesions in gastrointestinal adjacent tissue, and further to analyze the risk factors influencing positive rate of EUS-FNA. Methods The clinical data of 171 patients undergoing EUS-FNA from January 2009 to May 2016 were collected. The lesion location, size and characteristics, the number of needle passes, puncture suction negative pressure, size of puncture needle, and years of operator experience in EUS were retrospectively analyzed. Results The overall sensitivity, specificity, and accuracy of EUS-FNA in the diagnosis of malignant lesions were 78. 3％ ( 83/106) , 100. 0％ ( 65/65) , and 86. 5％( 148/171) , respectively. The univariable logistic regression analysis demonstrated that the risk factors of EUS-FNA were lesion location, lesion characteristics, and lesion size. In multivariate analysis, larger lesion size ( OR=1. 029, 95％CI: 1. 011-1. 047, P=0. 001) and lesion characteristics of solid ( OR=5. 098, 95％CI:1. 324-19. 633, P=0. 018) were independent factors affecting the positive rate of EUS-FNA. Among 171 cases performed by EUS-FNA, the incidence of postoperative complications was 1. 75％ ( 3/171 ) included 2 cases of fever and 1 case of acute pancreatitis, which were improved after conservative treatment. Conclusion EUS-FNA is a safe and effective method of cytological and histological diagnosis with high accuracy and sensitivity, importantly in distinguish malignancy from benign lesion in gastrointestinal adjacenttissue. Positive rate of diagnosis on malignant lesions by EUS-FNA is positively correlated with lesion size, and EUS-FNA positive rate of solid malignant lesions is significantly higher than that of cystic lesions.

Objective To study the diagnostic value and clinical efficacy of endoscopic ultrasound-guided fine needle aspiration ( EUS-FNA ) for mediastinal and abdominal lymphadenopathy. Methods Thirty patients who underwent EUS-FNA for mediastinal or abdominal lymphadenopathy between May 2009 and December 2015 were reviewed. The clinical efficacy of EUS-FNA was evaluated by pathological results and the follow-up. The EUS-FNA effect on clinical decision was also analyzed. Results Lesions were located in the mediastinum in 10 cases and in the abdomen in 20 cases. The total diagnostic accuracy, sensitivity, specificity, positive predictive value ( PPV) and negative predictive value ( NPV) of EUS-FNA were 96. 7%, 94. 7%, 100. 0%, 100. 0% and 91. 7%, respectively. Of all the 30 cases, 20 lymph glands were of unknown origin. The diagnostic accuracy, sensitivity, specificity, PPV and NPV of EUS-FNA in these lesions were 95. 0%, 88. 9%, 100. 0%, 100. 0% and 91. 7%, respectively. The combination of cytological and histological examination had higher accuracy ( 96. 7% VS 73. 3%, P=0. 026) and sensitivity ( 94. 7%VS 57. 8%, P= 0. 019 ) than cytological examination only. Immunohistochemistry stains were performed in 12 neoplastic cases, and 11 ( 91. 7%) were confirmed. The diagnosis by EUS-FNA had positive impact on clinical decisions in 27 patients ( 90. 0%) . Conclusion EUS-FNA is an effective approach for mediastinal and abdominal lymphadenopathy, and the result has a positive impact on clinical decisions. The combination of cytological and histological examination and application of ancillary techniques, such as immunohistochemistry stains, can improve the diagnostic efficacy of EUS-FNA.

Objective: To investigate the detection rates and inlfuencing factors of atrial septal defect (ASD) and ventricular septal defect (VSD) among neonates in two cities of East China and to provide scientiifc basis for the prevention, diagnosis, treatment and monitor of ASD and VSD. Methods: 2100 newborns with gestational age of at least 28 weeks were recruited consecutively from each city between 2013-09 and 2014-11. Data related to ASD and VSD were collected by questionnaires and echocardiographic screening was conducted within 7 days after birth. Results: A total of 4152 neonateswere examined with gestational age of (39.03 ± 1.29) weeks, among whom 2189 were male infants (52.72%), and age of mother was (26.32 ± 4.10) years old. Detection rates of ASD and VSD were 60.5‰ and 12.8‰ respectively, showing no significant difference between genders (P>0.05). Multivariate logistic regression analysis showed that maternal pre-pregnancy BMI and home decoration were the inlfuencing factors of ASD and maternal drug use in early pregnancy was the inlfuencing factor of VSD among newborns. Conclusions: Detection rates of ASD and VSD among neonates were relatively high in two cities of East China. Early screening is importtant to reduce the incidence of ASD and VSD and improve the prognosis.

Objective Toinvestigate the molecular characteristics including antibiotic resistance,strain type,serotype,virulence,biofilm formation of Streptococcus pneumoniae isolated from Shanghai adult patients.Methods A total of 37 non-repetitive S.pneumoniae isolates causing community acquired and hospital acquired infections of adults were collected from Shanghai Huashan Hospital from January 2011 to December 2013.The inhibitory zone diameter or minimum inhibitory concentrations (MICs) of 9 antimicrobial agents (penicillin,vancomycin,erythromycin,clindamycin,levofloxacin,cefprozi,ceftriaxone,cefotaxime and linezolid) were determined by Kirby-bauer (K-B) method or Etest method;Serotypes were tested by polymerase chain reaction (PCR) and S.pneumoniae antisera agglutination;Genomic characteristics of different serotype strains were determined by pulsed field gel electrophoresis (PFGE)method;Multilocus sequence types (MLST) was used for strain type;Semi quantitative biofilm formation test was used for the biological membrane formation.Ten main pneumococcal virulence genes (cbpA,pspA,cps2A,lytA,nana,pavA,piaA,ply,psaA and spxB) were detected by PCR and gel electrophoresis.Statistical analysis was performed using Stata software and association statistics were tested using Fisher's exact test.Results The most frequent serotypes were 19F (13.5％),23 F (13.5％),14 (10.8％),19A (10.8％).The penicillin resistance rate was 64.9％.Serotypes 19 F,19A and 23 F were significantly associated with penicillin resistance (x2 =5.89,P =0.015) and the isolates belonged to these serotypes were all multi-drug resistant (MDR).ST81 and ST271 showed high resistance rates to several antibiotics including penicillin (x2 =4.57,P =0.033).Biofilm formation was significantly associated with serotypes 19A (x2 =5.55,P =0.018) and strain type ST320 (x2 =4.33,P =0.037),but not associated with penicillin resistance (x2 =0.16,P =0.686).Virulence gene lytA,pavA,ply,psaA,spxB were found in all isolates.Conclusions Penicillin resistance rate of S.pneumoniae in adult is rising.Specific serotype,epidemic clone and antibiotic resistance are closely related,and can provide the basis for the infection control.The virulence factors such as PspA will be the new targets for vaccine development to reduce S.pneumoniae infection in the future.
