Objective To describe and analyze the epidemiological characteristics of scrub typhus in Huai'an, Jiangsu Province from 2006 to 2024 and explore the long-term incidence trend and distribution of high-risk areas, and to formulate targeted prevention and control strategies. Methods The scrub typhus case report data of Huai'an from 2006 to 2024 in the Chinese Disease Prevention and Control Information System were extracted for descriptive analysis. Results A total of 898 cases of scrub typhus were reported in Huai'an, with an average annual incidence rate of 0.96 per 100 000 from 2006 to 2024. There was a turning point in the incidence trend of scrub typhus in 2011. From 2006 to 2011, the annual percentage change (APC) was 47.09% (95% CI: 7.53 - 859.39), and the upward trend was statistically significant (P < 0.05). From 2012 to 2024, the APC was -2.12% (95% CI: -29.09 - 3.75), and the downward trend was not statistically significant. October and November were the high-incidence months, and the total concentration from 2006 to 2024 was 0.93, indicating that scrub typhus had strict seasonality. The circular distribution method estimated that the peak period of the epidemic was from October 11th to November 25th, and the peak day of incidence was November 3rd. Jinhu County was a high-incidence area. The ratio of male to female cases was 1.03. The age group with the highest reported incidence was 40 to < 80 years old. The occupation with the highest proportion was farmers, accounting for 78.03%. Conclusion From 2006 to 2024, scrub typhus in Huai'an shows a peak every 3 - 4 years. Middle-aged and elderly farmers are the key population at risk, and Jinhu County is a key area. In the future, targeted health education should be carried out to effectively control the prevalence of scrub typhus.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective To investigate the aggressive signs of benign spinal lesions appearing on medical imaging and their impact on diagnosis.Methods 139 cases of benign spinal lesions with aggressive signs confirmed by pathology of needle aspiration or surgery were reviewed,including 18 cases of osteoblastoma(OB),12 cases of aneurysmal bone cyst(ABC),14 cases of osteoenchondroma (OC),19 cases of Langerhans cell histiocytosis (LCH),15 cases of hemangioma (HA),34 cases of tuberculous spondylitis (TS),and 27 cases of pyogenic spondylitis (PS).All patients underwent radiography,119 cases CT plain scan,75 cases MRI scan,and 57 cases performed all the three imaging modalities.The aggressive signs,including bulging of posterior margin of the vertebral body,pathological compression fractures,ill-defined boundary,abnormal soft tissue mass,bone marrow and soft tissue edema were showed.The benign and malignant misdiagnosis rate,the consistent rate of diagnosis with pathology were statistically analysed.Results Bulging of posterior margin of the vertebral body were found in 2 cases of OB,1 case ABC,3 cases LCH,1 case OC,6 cases HA,6 cases TS,2 cases PS.Pathological compression fracture were found in 6 cases of OB,10 cases ABC,16 cases LCH,4 cases HA,21 cases TS,16 cases PS.Ill defined boundary were found in 3 cases of OB,8 cases HA,34 cases TS,27 cases PS.The abnormal soft tissue around spine were found in 6 cases of OB,2 cases ABC,15 cases LCH,10 cases TS,15 cases PS.Bone marrow and soft tissue edema were found in 5 cases of OB,4 cases ABC,10 cases LCH,4 cases HA,30 cases TS,27 cases PS.For benign and malignant misdiagnosis rate,MRI was better than CT(P＜ 0.05).For accuracy of the consistent rate with pathology,CT was better than MRI(P＜0.05).The integrated application of the three imaging methods could significantly improve diagnostic accuracy (P＜0.05).Conclusion The imaging features benign spinal lesions are various,which may be associated with aggressive signs.A comprehensive method combined with three kinds of imaging methods,is a simple and feasible way to avoid the misdiagnosis.
