ObjectiveTo analyze the epidemiological characteristics of 21 respiratory pathogens in influenza-like illness (ILI) cases in Jing’an District, Shanghai in 2024, and to provide a scientific basis for the prevention and control of respiratory infectious diseases. MethodsData of1 907 ILI cases at four sentinel hospitals in Jing’an District were collected from January to December 2024. Nasopharyngeal swab samples were collected and tested for 21 respiratory pathogens using polymerase chain reaction (PCR) methods. Chi-square test and Cochran-Armitage trend test were used for data analyses. ResultsAmong the 1 907 ILI cases, 1 340 were tested positive (70.27%), including 1 160 (60.83%) virus-positive cases, 424 (22.23%) bacteria-positive cases , and 86 (4.51%) positive cases of other pathogens (fungi, mycoplasma, and chlamydia). The top five viruses by detection rate were: influenza virus (14.84%), SARS-CoV-2 (14.47%), rhinovirus (12.69%), adenovirus (7.08%), and parainfluenza virus (6.71%). The top two bacteria by detection rate were Streptococcus pneumoniae (14.47%) and Haemophilus influenzae (10.33%). Among other pathogens (fungi, mycoplasma, and chlamydia), Mycoplasma pneumoniae showed the highest detection rate (4.30%). In terms of age distribution, statistically significant differences were observed in the detection rates of SARS-CoV-2, Legionella, and Klebsiella pneumoniae (P<0.05), with the highest rates found in individuals aged 65 years and above. Statistically significant differences were also found in the detection rates of rhinovirus, adenovirus, enterovirus, common coronavirus, respiratory syncytial virus, bocavirus, parainfluenza virus, human metapenu-movirus, Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae among different age groups (P<0.05), all showing the highest detection rates in the 0‒<15 years age group. In terms of seasonal distribution, SARS-CoV-2, adenovirus, parainfluenza virus, enterovirus, Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae showed epidemic peaks in summer; rhinovirus, common coronavirus, bocavirus, and Klebsiella pneumoniae had higher detection rates in autumn. Influenza virus exhibited a peak incidence during winter, while human metapenu-movirus peaked in winter and spring. Significant differences in co-infection detection rates were observed among age groups, with the rate in children aged 0‒<15 years (34.81%) being the highest. The co-infection detection rate was higher in males than in females (P=0.019). Both the single-pathogen detection rate and the co-infection detection rate (P<0.001) varied significantly across seasons: the single-pathogen detection rate was highest in winter (62.06%), while the co-infection detection rate peaked in summer (31.20%) and was lowest in winter (14.52%). ConclusionBased on detection rates, the main pathogens in the ILI population of Jing’an District, Shanghai, 2024 were influenza virus, SARS-CoV-2, rhinovirus, adenovirus, parainfluenza virus, common coronavirus, enterovirus, Human metapenu-movirus, Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae. Pathogen detection rates varied by age and season. Coinfection rates were much higher in children than in adults, higher in males than in females, and peaked in summer while being lowest in winter.

Objective:To evaluate the morphological and functional changes of the heart during second trimester fetuses with ventricular septal defect (VSD) using fetal heart quantification (fetal HQ) technology.Methods:A prospective study was conducted from July 2022 to January 2024 at Chengdu Women′s and Children′s Central Hospital, collecting 91 singleton fetuses diagnosed with isolated VSD (VSD group) and 91 normal fetuses matched for gestational age (control group). Fetal HQ technology was used to measure the length and width of the four-chamber view of the fetal heart, obtaining the global sphericity index (GSI). Speckle tracking technology was used to track the endocardial motion trajectories of the left and right ventricles during diastole and systole, obtaining parameters such as left and right ventricular global longitudinal strain (LV-GLS and RV-GLS), end-diastolic diameter (EDD), 24-segment sphericity index (SI), 24-segment fraction of shortening (FS), left ventricular ejection fraction (LV-EF), fraction of area change (FAC), left ventricular stroke volume (LV-SV), and left ventricular cardiac output (LV-CO).The differences between groups were compared, and the correlations between the values of VSD and GSI, GLS, and FAC were evaluated.Results:The EDD of the left ventricular segments 20-23 in the VSD group was lower, while the SI value of the right ventricular segments 1-4 in the VSD group was higher than that in the control group (all P<0.05). There was no statistically significant difference in GSI between the two groups ( P>0.05). LV-GLS in the VSD group was lower than that in the control group ( P<0.05). There was no statistically significant difference in RV-GLS ( P>0.05). Values of LV-FAC, LV-EF, LV-SV, and LV-CO in the VSD group were significantly lower than those in the control group (all P<0.05). The FS value of left ventricular segments 1-10 in the VSD group presented lower, but the FS value of right ventricular segments 7-21 higher compared to controls(all P<0.05). LV-GLS and LV-FAC absolute values were negatively correlated with the size of VSD ( r=-0.309, P=0.004; r=-0.264, P=0.015), while GSI, RV-GLS, and RV-FAC showed no significant correlation with the size of VSD (all P>0.05). Conclusions:The overall sphericity index of second trimester VSD fetuses is normal, but there are changes in the shape of the left ventricular apical segments and the right ventricular basal segments, with the left heart chamber tending to be flatter and the right heart chamber more fusiform. The left ventricular systolic function of VSD fetuses is significantly reduced, the local systolic function of right ventricular increases while the global systolic function shows no significant change. The absolute values of LV-GLS and LV-FAC in VSD fetuses are negatively correlated with the size of VSD.

Objective:To evaluate the predictive value of preoperative frailty combined with nutritional status for prolonged postoperative ileus (PPOI) in the patients with gynecological malignancies.Methods:Patients undergoing elective surgery for gynecological malignancies in the Affiliated Hospital of Jiangnan University from April 2022 to February 2023 were selected. The Frail scale was used to evaluate the frailty within 24 h of admission, and the nutritional status was evaluated by the Controlling Nutritional Status score. The general characteristics of patients and occurrence of PPOI were recorded, and the risk factors for PPOI were analyzed by multivariate logistic regression. The ability of frailty, nutritional status and their combination to predict PPOI was assessed by the receiver operating characteristic curve.Results:Two hundred and fourteen patients were finally included, 52 cases developed of PPOI, and 98 cases were frail patients. Preoperative frailty combined with moderate to severe malnutrition was an independent risk factor for PPOI in the patients with gynecological malignancies ( P<0.05), and the area under the curve in predicting the occurrence of PPOI was 0.796 (95% confidence interval 0.736-0.857) in the patients with gynecological malignancies. Conclusions:Preoperative frailty combined with moderate to severe malnutrition has a higher accuracy in predicting PPOI in the patients with gynecological malignancies.
