AIM:To analyze the characteristics of pathogenic bacteria in patients with infectious eye diseases at Shangrao Central Hospital from 2020 to 2024, providing a basis for the precise clinical prevention and control and the development of effective strategies.METHODS: A retrospective analysis was carried out on clinical specimens including the cornea, lacrimal duct, conjunctiva, and intraocular fluid samples, from patients with infectious eye diseases between May 2020 and December 2024. All the specimens underwent microbiological cultures and identification.RESULTS: A total of 447 patients enrolled ultimately in this study, including 250 males and 197 females, with an average age of 58.5±17.1 y. Among the 447 ocular specimens, bacterial infection was confirmed in 146 cases(32.7%). Of these positive samples, male patients accounted for 63.7%(93/146)and patients aged 51-70 y had the highest infection rate(88/146, 60.3%). Furthermore, migrant workers represented the predominant demographic affected by ocular infections, accounting for an overwhelming majority at 95.9%(140/146). When compared to other etiologies of disease, trauma emerged as the primary cause of ocular infections(P<0.01). In cases of bacterial ocular infections, Gram-positive cocci comprised approximately 61.2%, with Staphylococcus identified as the principal pathogen affecting the lacrimal duct, conjunctivae, and intraocular fluid. Streptococcus pneumoniae was found to be the main pathogen associated with corneal infections. Gram-negative bacteria were predominantly Pseudomonas aeruginosa. Fungal infections were observed in an alarming rate of 91.8% among corneal specimens. Fusarium was identified as the leading fungal pathogen responsible for these cases at a proportion of 45.9%.CONCLUSION: The distribution of pathogenic bacteria causing ocular infections demonstrates obvious tissue specificity. Trauma is identified as a major inducement of corneal fungal infection. Clinically, it is essential to pay particular attention to patients with ocular trauma, especially those engaged in agricultural labor who present with ocular infections, and fungal tests should be conducted as early as possible.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the value of cardiovascular MR (CMR) T 1 mapping in evaluating myocardial injury in patients recovered from COVID-19. Methods:The clinical and image data of 15 patients with COVID-19 (9 with moderate clinical manifestation, 6 with severe clinical manifestation) who underwent CMR screening at 3 months after being discharged from the Second People′s Hospital of Fuyang City during May 2020 to June 2020 were prospective collected. Fifteen COVID-19 patients were selected as case group, and another 11 healthy volunteers were selected as control group. A standardized CMR protocol included cine, native and enhanced T 1 mapping, late gadolinium enhancement (LGE). Cardiac functional parameters, native T 1 value of left ventricular and extracellular volume fraction (ECV) were measured. One way ANOVA was used to assess the difference between CMR parameters among moderate and severe manifestation groups and control group, and LSD- t was used to assess the difference between the three groups. Results:LGE value was negative in all subjects. ECV values were higher in recovered COVID-19 patients with either moderate (27.9%±2.7%) or severe manifestation (30.0%±3.7%) than control group (23.2±1.9%) ( P<0.05); there was no significant difference of ECV values between recovered COVID-19 patients with moderate and severe manifestation ( P=0.100). There was no difference of native T 1 values and other functional and morphologic parameters of left ventricular and right ventricular among recovered COVID-19 patients with moderate and severe manifestation and control group ( P>0.05). Conclusion:CMR myocardial tissue ECV increase in patients who recovered from COVID-19, suggesting subclinical myocardial injury.

Tocilizumab has been reported to attenuate the "cytokine storm" in COVID-19 patients. We attempted to verify the effectiveness and safety of tocilizumab therapy in COVID-19 and identify patients most likely to benefit from this treatment. We conducted a randomized, controlled, open-label multicenter trial among COVID-19 patients. The patients were randomly assigned in a 1:1 ratio to receive either tocilizumab in addition to standard care or standard care alone. The cure rate, changes of oxygen saturation and interference, and inflammation biomarkers were observed. Thirty-three patients were randomized to the tocilizumab group, and 32 patients to the control group. The cure rate in the tocilizumab group was higher than that in the control group, but the difference was not statistically significant (94.12% vs. 87.10%, rate difference 95% CI-7.19%-21.23%, P = 0.4133). The improvement in hypoxia for the tocilizumab group was higher from day 4 onward and statistically significant from day 12 (P = 0.0359). In moderate disease patients with bilateral pulmonary lesions, the hypoxia ameliorated earlier after tocilizumab treatment, and less patients (1/12, 8.33%) needed an increase of inhaled oxygen concentration compared with the controls (4/6, 66.67%; rate difference 95% CI-99.17% to-17.50%, P = 0.0217). No severe adverse events occurred. More mild temporary adverse events were recorded in tocilizumab recipients (20/34, 58.82%) than the controls (4/31, 12.90%). Tocilizumab can improve hypoxia without unacceptable side effect profile and significant influences on the time virus load becomes negative. For patients with bilateral pulmonary lesions and elevated IL-6 levels, tocilizumab could be recommended to improve outcome.

Objective:To analyze the clinical characteristics of patients with novel coronavirus pneumonia (COVID-19) and the factors influencing mild cases developing into severe cases, so as to provide a basis for clinical screening, prevention and treatment of potential severe cases.Methods:Retrospective analysis was performed on the clinical characteristics of 168 cases who were admitted to two tertiary general hospitals in Anhui province and diagnosed with COVID-19 from January 20 to March 4, 2020. According to the classification criteria in the COVID-19 diagnosis and treatment program (trial version 6) issued by the National Health Commission, the mild and common cases were classified as the mild group ( n=137), and the severe and critical cases were classified as the severe group ( n=31). The general data, epidemiological history, clinical manifestations, laboratory examination and imaging indexes of the two groups were compared. Univariate analysis was performed. Then multivariate Logistic regression analysis was conducted on the factors with statistically significant differences in univariate analysis to obtain independent influencing factors of the occurrence of severe COVID-19. Results:Among the 168 COVID-19 patients, 95 were male and 73 were female, with an average age of 42.6±15.8 years old. The mean age of the mild group was younger than that of the severe group (40.5±15.5 vs 51.6 ±14.1, P<0.01). The proportion of patients combined with hypertension (29.0% vs 10.9%), diabetes (25.8% vs 2.2%, P=0.005) and two or more underlying diseases (29.0% vs 4.4%, P=0.006) in the severe group were significantly higher than those in the mild group. In the severe group, the proportion of patients receiving initial treatment in Medical institutions below secondary hospitals was significantly higher than that in the mild group ( P<0.01), and the time between symptom onset and diagnosis was longer [(8.00±3.27) d vs (6.49±3.90) d, P=0.048]. There was no significant difference in the initial symptoms between the mild group and the severe group. However, the body temperature was higher in the severe group [(38.80±0.67)℃ vs (37.9±0.60)℃, P<0.01]. At the time of admission, the lymphocyte percentage of the severe group was significantly lower than that of the mild group [(18.20±9.13)% vs (24.43±10.43)%, P<0.01], while C-reactive protein, interleukin-6 (IL-6), D-dimer, LDH, aspartate and aminotransferase were significantly higher than that of the mild group ( P<0.01). CT imaging showed that 11 (8%) patients in the mild group had lesions confined to a single lobe of the lung, while all patients in the severe group had multi-lobe lesions ( P<0.01). All the 168 COVID-19 patients in this study were cured, and the length of hospital stay in the severe group was significantly longer than that in the mild group [(24.71±7.72) d vs (20.28±7.67) d, P=0.021]. According to multivariate binary Logistic regression analysis, age ( P=0.042), diabetes ( P=0.021), body temperature at admission ( P=0.001), and IL-6 measured at admission ( P=0.008) were independent factors affecting COVID-19 to severe progress. Conclusions:Strengthening the professional knowledge training of primary hospitals is helpful for early diagnosis of COVID-19. Patients with older age, combined with diabetes, high initial fever and significantly increased IL-6 level are more possibly to develop into severe disease. Early identification and prevention should be carried out.

Objective: To evaluate the feasibility and potential value of comprehensive geriatric assessment (CGA) in elderly (≥60 years) patients with newly diagnosed acute myeloid leukemia (AML) in China. Methods: The CGA results of 83 newly diagnosed AML (non-APL) patients from 16 hospitals in Beijing and Tianjin between March 2016 and December 2017 were prospectively collected and analyzed. The clinical data, treatment and follow-up information were also collected. Results: Of 83 newly diagnosed elderly AML patients, 81 patients (97.6%) completed all designated CGA assessment. The median number of impaired scales of the CGA assessment in the studied population was 2(0-6). Sixteen patients (19.3%) showed no impairments according to the geriatric assessment scales implem ented by this study. The distributions of impaired scales were as follows: impairment in ADL, 55.4%; IADL impairment, 42.2%; MNA-SF impairment, 48.2%; cognitive impairment, 15.7%; GDS impairment, 31.7%; HCT-CI impairment, 19.5%, respectively. In patients with "good" ECOG (n=46), the proportion of impairment for each CGA scale ranged from 6.5% to 37.0% and 32 patients (68.9%) had at least one impaired CGA scale. Survival analysis showed that the number of impaired scales of the CGA was significantly correlated with median overall survival (P=0.050). Conclusions CGA was a tool with feasibility for the comprehensive evaluation in elderly AML patients in China. Combined with age and ECOG, CGA may be more comprehensive in assessing patients’ physical condition.

Objective To explore the clinical characteristics and causes of death in patients with acute heart failure at aged 75 and over.Methods The prospective study collected 175 patients with acute heart failure from January 2012 to December 2014.They were divided into ≥75 years old group and＜75 years old group and the general clinical data were recorded.Follow-up was performed mainly by telephone with supplemented hospitalization follow-up and outpatient follow-up.Survival rates were assessed by Kaplan-Meier method.The survival rate difference between the two groups was compared using the log-rank test.Multivariate Cox proportional hazards regression analysis was used to determine the independent risk factors for death.Results The proportions of ischemic heart disease,hypertension and old myocardial infarction were higher in the elderly group than in the young group with a higher proportion of male,diabetes and body mass index in ＜75 years old group.Elderly group had a higher level of left ventricular ejection fraction(LVEF)and a lower level of total cholesterol,triglycerides and low density lipoprotein cholesterol(LDL-C).Kaplan-Meier curves showed that allcause mortality(x2 =4.005,P =0.045) and non-cardiovascular mortality(x2 =4.418,P =0.041) were significantly higher in the elderly group than in the younger group,whereas cardiovascular mortality had no significant difference between the two groups (x2 =0.754,P =0.385).In patients with noncardiovascular mortality,12 cases (63.2％)died of pulmonary infection in elderly group,3 cases(25.0％) died of lung infection in younger group,and the difference was statistically significant between the 2 groups (x2 =4.288,P =0.038).Multivariate Cox proportional hazards regression analysis showed that age≥75 years was an independent predictor for both non-cardiovascular mortality [HR(95％CI):2.71(1.50-6.55),Wald x2 =2.266,P=0.038]and all-cause mortality[HR(95 ％CI):1.75(1.28-3.13),Wald x2 =2.914,P=0.026]in patients with acute heart failure.Conclusions Age ≥75 years is an independent risk factor for all dead patients with acute heart failure and noncardiovascular death,but it is not the independent risk factors for cardiovascular death,which is of great significance to establish a more rational treatment strategy for senile heart failure.
