Objective To study the economic burden caused by healthcare-associated infection(HAI)in patients with severe acute pancreatitis(SAP),and provide theoretical basis for formulating HAI prevention and control measures.Methods Patients with SAP discharged from a tertiary first-class hospital in Jiangxi Province from July 1,2023 to June 30,2024 were selected as the study subjects.Information including demographic characteristics,clinical data,and hospitalization expense were collected.Patients were divided into a HAI group and a non-HAI group according to HAI occurrence.A propensity score matching(PSM)method was used to conduct a 1∶2 ma-tching,and differences in the length of hospital stay and hospitalization expense between the two groups of patients after PSM were compared.Results A total of 709 patients were included in the analysis,out of which 65 cases ex-perienced HAI,with a HAI incidence of 9.17％.After PSM,all 65 patients in the HAI group were successfully matched.The length of hospital stay,total hospitalization expense,expenses of medication and hygiene product of patients in the HAI group were all higher than those in the non-HAI group,and differences were all statistically sig-nificant(all P＜0.001).Patients who experienced≥2 episodes of HAI had a higher economic burden than those who experienced only once(P＜0.05).HAI of bloodstream,abdomen,digestive system,and respiratory system significantly increased the economic burden of patients(all P＜0.05).Conclusion HAI in SAP patients can extend the length of hospital stay and increase economic burden of patients.Targeted infection prevention and control mea-sures should be formulated to reduce the incidence of HAI and save medical resources.

Objective To investigate the clinical features of cerebral venous sinus thrombosis (CVST)in patients with malignancy as well as its underlying pathogenesis. Methods The clinical data, including clinical presentation, laboratory results, neurological images were retrospectively reviewed in hospital patients with active malignant tumor and cerebral venous thrombosis from January 2006 to December 2016. Results Among the 586 CVST patients, 24 patients (4.10%) were with malignant tumor. Among these 24 patients, there were 8 males and 16 females with an average age of (39.88 ± 21.71) years old. Four patients (16.67%) had the risk factors of cerebral venous sinus thrombosis, while the other 20 patients(83.33%)had not any such risk factors.At the symptom onset of CVST, 22 patients(91.67%) had headache and focal neurological deficit, such as limbs weakness and numbness. The common substyles of malignant tumor were lung cancer (33.33%), breast cancer (29.17%)and acute lymphocytic leukemia(20.83%).Most patients(58.33%)were found to have cerebral metastasis.22 patients (91.67%) had elevated plasma D-dimmer level, and 19 patients (79.17%) had elevated plasma cancer biochemical marker levels.Conclusions Cancer-related CVST had the features including lacking conventional risk factors, elevated plasma D-dimmer and cancer biochemical marker levels.Cerebral metastasis and hypercoagulable state may be responsible for the pathogenesis of CVST.

Objective To study the clinical features and possible pathogenesis of acute ischemic stroke in renal cell cancer patients. Methods The clinical data from in-hospital patients with renal cell cancer who developed acute ischemic stroke were collected, including the patients with renal cell cancer who developed acute ischemic stroke during anti-cancer therapies and those patients with acute ischemic stroke who were firstly diagnosed to have renal cell cancer during anti-stroke therapies between January 2003 and December 2015. Results A total of 2516 patients with renal cell cancer were screened, and there were 36 patients (1.43%) with acute ischemic stroke. Out of the 36 patients, there were 29 men (80.56%) and 7 women (19.44%). Their age ranged from 45 to 68 years, with a average age of (65.11 ± 14.77) years. Eight patients (22.22%) had some conventional cardiovascular risk factors, while the other 28 patients (77.78%) had no such risk factors. Magnetic resonance imaging (MRI) scans at the acute stage of ischemic stroke were carried out for all these patients. Based on the diffusion weighted imaging (DWI) of MRI, 8 patients (22.22%) had single lesion and 28 patients (77.78%) had multiple lesions in different arterial territories in their brains. The pathological types of renal cell cancer were:suprarenal epithelioma (18 patients, 50.00%), papillary cell carcinoma (12 patients, 33.33%) and chromophobe renal cell carcinoma (6 patients, 16.67%). Metastases were found 10 patients (27.78%) out of the 36 patients. Blood biochemical examination showed that 28 patients had elevated plasma D-dimer level, 22 patients had elevated plasma cancer antigen (CA)125 level, and 17 patients had elevated plasma carcinoembryonic antigen (CEA) levels. Conclusions It is suggested that the renal cell cancer associated stroke is characterized by lacking of traditional risk factors and having multiple lesions in brain;and that the elevated plasma D-dimer, CA125 and CEA levels may lead to hypercoagulable state and lead to ischemic stroke eventually .
