Diabetic retinopathy (DR) is one of the most frequent complications of diabetes (T2DM), which is the main eye disease causing blindness in adults in recent years. At present, glucagon-like peptide-1 receptor agonists (GLP-1RA) have become the main drugs used in the treatment of diabetes due to its superior hypoglycemic, lipid-lowering, hypertensive and cardiovascular effects. A large number of studies have shown that GLP-1RA drugs can protect retinal microvascular and optic nerves in the treatment of diabetes through various ways, but some studies have found that GLP-1RA drugs represented by semaglutide may lead to the progress of DR. Therefore, GLP-1RA should be used cautiously for patients who with severe non-proliferative DR or proliferative DR. Regardless of whether T2DM patients are complicated with DR, the fundus retinal condition should be monitored regularly after the use of GLP-1RA drugs, and timely countermeasures should be taken when DR occurs and develops. The benefits of GLP-1RA used by diabetes patients are obvious to all, and scientific and rational drug use can prevent the occurrence and progress of DR, which can better benefit DR Patients.

Objective:To investigate and summarize pediatric patients with severe Mycoplasma pneumoniae pneumonia (MPP) presenting with varied clinical and chest imaging features in order to guide the individualized treatment. Methods:This was a retrospective cohort study. Medical records of clinical, imaging and laboratory data of 505 patients with MPP who were admitted to the Department Ⅱ of Respirology Center, Beijing Children′s Hospital, Capital Medical University from January 2016 to October 2023 and met the enrollment criteria were included. They were divided into severe group and non-severe group according to whether lower airway obliterans was developed. The clinical and chest imaging features of the two groups were analyzed. Those severe cases with single lobe ≥2/3 consolidation (lobar consolidation) were further divided into subtype lung-necrosis and subtype non-lung-necrosis based on whether lung necrosis was developed. Comparison on the clinical manifestations, bronchoscopic findings, whole blood C-reactive protein (CRP) and other inflammatory indicators between the two subtypes was performed. Comparisons between two groups were achieved using independent-sample t-test, nonparametric test or chi-square test. Univariate receiver operating characteristic (ROC) curve analyses were performed on the indicators such as CRP of the two subtypes. Results:Of the 505 cases, 254 were male and 251 were female. The age of the onset was (8.2±2.9) years. There were 233 severe cases, among whom 206 were with lobar consolidation and 27 with diffuse bronchiolitis. The other 272 belonged to non-severe cases, with patchy, cloudy infiltrations or single lobe <2/3 uneven consolidation or localized bronchiolitis. Of the 206 cases (88.4%) severe cases with lobar consolidation, 88 harbored subtype lung-necrosis and 118 harbored subtype non-lung-necrosis. All 206 cases (100.0%) presented with persistent high fever, among whom 203 cases (98.5%) presented with inflammatory secretion obstruction and plastic bronchitis under bronchoscopy. Of those 88 cases with subtype lung-necrosis, there were 42 cases (47.7%) with dyspnea and 39 cases (44.3%) with moderate to massive amount of pleural effusion. There were 35 cases (39.8%) diagnosed with lung embolism during the disease course, of which other 34 cases (38.6%) were highly suspected. Extensive airway mucosal necrosis was observed in 46 cases (52.3%), and the level of their whole blood CRP was significantly higher than that of subtype non-lung-necrosis (131.5 (91.0, 180.0) vs. 25.5 (12.0, 43.1) mg/L, U=334.00, P<0.001). They were regarded as subtype "lung consolidation-atelectasis-necrosis". Of those 118 cases with subtype non-lung-necrosis, 27 cases (22.9%) presented with dyspnea and none were with moderate to massive amount of pleural effusion. Sixty-five cases (55.1%) presented with plastic bronchitis and localized airway mucosal necrosis was observed in 32 cases (27.1%). They were deemed as subtype "lung consolidation-atelectasis". ROC curve analyses revealed that whole blood CRP of 67.5 mg/L on the 6-10 th day of disease course exhibited a sensitivity of 0.96, a specificity of 0.89, and an area under the curve of 0.97 for distinguishing between these two subtypes among those with lobar consolidation. Conclusions:Pediatric patients with severe MPP present with lobar consolidation or diffuse bronchiolitis on chest imaging. Those with lobar consolidation harbor 2 subtypes as "lung consolidation-atelectasis-necrosis" and "lung consolidation-atelectasis". Whole blood CRP of 67.5 mg/L can be applied as an early discriminating indicator to discriminate between these two subtypes.

Objective:To develop and validate a risk prediction model for cognitive frailty in elderly patients with type 2 diabetes.Methods:A total of 483 elderly patients with type 2 diabetes who visited Tianjin First Central Hospital from June to December 2022 were selected using convenience sampling. They were randomly divided into a modeling group ( n=338) and a validation group ( n=145). Data were collected using a self-designed general information questionnaire, the Short-Form Mini Nutritional Assessment (MNA-SF), the Geriatric Depression Scale-15 (GDS-15), the Frailty Phenotype (FP), the Montreal Cognitive Assessment (MoCA), and the Clinical Dementia Rating (CDR). Logistic regression analysis was performed to identify the influencing factors. A cognitive frailty risk prediction nomogram model was constructed based on the results. The model was validated in the validation group, and its predictive performance and clinical applicability were evaluated using the area under the receiver operating characteristic curve ( AUC), calibration curve, and clinical decision curve analysis. A total of 483 questionnaires were distributed and all were returned as valid, resulting in a 100.0% response rate. Results:The prevalence of cognitive frailty in the 483 elderly patients with type 2 diabetes was 20.3% (98/483). Age, regular exercise, duration of diabetes, HbA1c levels, depression and nutritional status were identified as predictive factors in the model. The AUC of the model was 0.886, and the Hosmer-Lemeshow test showed a χ 2 value of 8.004 ( P=0.433). The optimal cutoff value was 0.335, and the accuracy was 89.0%. Conclusions:The prediction model demonstrates good fit and strong predictive performance, and can intuitively and easily identify elderly patients with type 2 diabetes who are at high risk of cognitive frailty, providing a reference for early screening and intervention.

Objective:To study the influence of serum triggering receptor expressed on myeloid cells 1(TREM-1)level on prognosis in elderly patients with sepsis and acute respiratory distress syndrome(ARDS).Methods:A total of 100 elderly patients with sepsis were selected as the research objects.All the patients with sepsis were divided into sepsis ARDS group and sepsis non-ARDS group.General data and TREM-1 level were compared between the two groups.The patients with sepsis ARDS were divided into death group and survival group according to the survival status during the 28-day follow-up.TREM-1 level, acute physiology and chronic health evaluation(APACHE)Ⅱ score and SOFA score were compared between the two groups.The correlation between serum TREM-1 level and procalcitonin(PCT), APACHE Ⅱ score and SOFA score was analyzed.The survival rate of high TREM-1 level group and low TREM-1 level group was compared.Results:The age, white blood cell(WBC), PCT, APACHE Ⅱ score, SOFA score and TREM-1 level of sepsis ARDS patients were significantly higher than those of non-ARDS patients( t=2.722, 6.088, 11.55, 6.889, 4.661, 6.122, all P<0.05). The incidence of sepsis ARDS patients with chronic obstructive pulmonary disease was significantly higher than that of non-ARDS patients( χ2=7.895, P<0.05). Serum TREM-1 level, APACHE Ⅱ score and SOFA score of ARDS patients in death group were significantly higher than those in survival group( t=3.293, 6.173, 4.255, all P<0.05). Serum TREM-1 level was positively correlated with PCT, APACHE Ⅱ score and SOFA score( t=0.553, 0.602, 0.636, P<0.001). The Kaplan-Meier survival curve showed that the survival rate of high TREM-1 level group was significantly lower than that of low TREM-1 level group( χ2=3.999, P=0.036). Cox regression analysis showed that TREM-1 level was a risk factor for the prognosis of ARDS patients with sepsis( HR=1.893, 95% CI: 1.049-3.414). Conclusions:Serum TREM-1 level is significantly increased in elderly patients with sepsis ARDS, which is closely related to the prognosis and can be used as a potential prognostic biomarker.

Objective:To investigate the clinical settings, antibiotic susceptibilities, management and outcomes of streptococcal endophthalmitis.Methods:A retrospective observational case series study. Fifty six eyes of 56 patients diagnosed with streptococcal endophthalmitis in Eye & ENT Hospital, Fudan University from 2012 to 2022 were collected. The treatment followed the general principles of relevant guidelines, including pars plana vitrectomy (PPV), vitreous injection of antibiotics (IVI), vitreous injection of glucocorticoids and systemic application of antibiotics. The follow-up time was (11.9±17.0) months. Patients' clinical characteristics, pathogenic distribution and antibiotic susceptibilities, treatment and outcomes in their medical records were retrospectively collected and analyzed.Results:All 56 patients had monocular onset, including 39 (69.6%, 39/56) males and 17 (30.4%, 17/56) females, 26 (46.4%, 26/56) with left eyes involved and 30 (53.6%, 30/56) with right eyes involved. Their average age was (25.0±24.4) years. Ocular trauma was the leading cause of streptococcal endophthalmitis (73.2%, 41/56), followed by ophthalmic surgery (23.2%, 13/56) and endogenous infection (3.6%, 2/56). The streptococcal species included Streptococcus viridans (50.0%, 28/56), Streptococcus pneumoniae (18/56, 32.1%) and β-hemolytic Streptococcus (17.9%, 10/56). The susceptibility rates of Streptococcus to penicillin, cefatriaxone, vancomycin and levofloxacin were 66.0%, 57.1%, 94.1% and 92.4%, respectively. Patients received PPV+IVI and IVI as initial treatment were 49 eyes (87.5%, 49/56) and 7 eyes (12.5%, 7/56), respectively. Vitreous injection of glucocorticoids were performed in 17 eyes (30.4%, 17/56); and systemic antibiotics were applied in 52 cases (92.9%, 52/56). At the final follow-up, 47 eyes were recorded with visual acuity. Twenty (35.7%, 20/56) had best corrected visual acuity (BCVA)≥0.05 and 27 (48.2%, 27/56) had BCVA <0.05, of which 1 (1.8%, 1/56) had an eyeball enucleation. The etiology of endophthalmitis, streptococcal species, initial treatment with PPV, vitreous injection of glucocorticoids, and systemic antibiotics did not significantly affect patients' visual outcomes ( P>0.05). Timely visit to the hospital after the onset of symptoms (≤3 days) was significantly associated with achieving a final BCVA above 0.05 ( P=0.025). Conclusions:Ocular trauma was the primary cause of streptococcal endophthalmitis. Streptococcus viridans is the most common pathogenic bacterium. Streptococci had high susceptibility to vancomycin, but patients' visual outcomes were poor.

China has classified the Corona Virus Disease 2019(COVID-19) as a statutory category B infectious disease and managed it according to Category B since January 8, 2023.In view that Omicron variant is currently the main epidemic strain in China, in order to guide the treatment of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infection in children with the times, refer to the Diagnosis and Treatment Protocol for Novel Coronavirus Infection (Trial 10 th Edition), Expert Consensus on Diagnosis, Treatment and Prevention of Novel Coronavirus Infection in Children (Fourth Edition) and the Diagnosis and Treatment Strategy for Pediatric Related Viral Infections.The Expert Consensus on the Diagnosis, Treatment and Prevention of Novel Coronavirus Infection in Children (Fifth Edition) has been formulated and updated accordingly on related etiology, epidemiology, pathogenic mechanism, clinical manifestations, auxiliary examination, diagnosis and treatment, and added key points for the treatment of COVID-19 related encephalopathy, fulminating myocarditis and other serious complications for clinical reference.

Monkeypox is a zoonotic disease.Previous studies have shown that children are vulnerable to monkeypox and are also at high risk for severe disease or complications.In order to improve pediatricians′ understanding of monkeypox and achieve early detection, early diagnosis, early treatment and early disposal, the committee composed of more than 40 experts in the related fields of infectious diseases, pediatrics, infection control and public health formulate this expert consensus, on the basis of the latest clinical management and infection prevention and control for monkeypox released by the World Health Organization (WHO), the guidelines for diagnosis and treatment of monkeypox (version 2022) issued by National Health Commission of the People′s Republic of China and other relevant documents.During the development of this consensus, multidisciplinary experts have repeatedly demonstrated the etiology, epidemiology, transmission, clinical manifestations, laboratory examinations, diagnosis and differential diagnosis, treatment, discharge criteria, prevention, case management process and key points of prevention and control about monkeypox.

Since December 2019, severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infections have raged globally for more than 2 years.China has always adopted scientific and effective prevention and control measures to achieved some success.However, with the continuous variation of SARS-CoV-2 cases and imported cases from abroad, the prevention and control work has become more difficult and complex.With the variation of the mutant strain, the number of cases in children changed, and some new special symptoms and complications were found, which proposed a new topic for the prevention and treatment of SARS-CoV-2 infection in children in China.Based on the third edition, the present consensus according to the characteristics of the new strain, expounded the etiology, pathology, pathogenesis, and according to the clinical characteristics and experience of children′s cases, and puts forward recommendations on the diagnostic criteria, laboratory examination, treatment, prevention and control of children′s cases for providing reference for further guidance of effective prevention and treatment of SARS-CoV-2 infection in children in China.
