RESUMO
Sepsis, a common and life-threatening condition in critically ill patients, is a leading cause of death in intensive care units. Over the past few decades, there has been significant improvement in the understanding and management of sepsis. However, the mortality rate remains unacceptably high, posing a prominent challenge in modern medicine and a significant global disease burden. A total of 295 patients with sepsis admitted to the hospital from January 2021 to December 2022 were collected and divided into survival group and death group according to their 28-day survival status. The differences in general clinical data and laboratory indicators between the 2 groups were compared. Receiver operating characteristic curve analysis was used to evaluate the predictive value of platelet (PLT) and procalcitonin (PCT) for the prognosis of sepsis patients within 28 days. A total of 295 patients were diagnosed with sepsis, and 79 died, with a mortality rate of 26.78%. The PLT level in the death group was lower than that in the survival group; the PCT level in the death group was higher than that in the survival group. The receiver operating characteristic curve showed that the area under the curve of PCT and PLT for evaluating the prognosis of sepsis patients were 0.808 and 0.804, respectively. Kaplan-Meier survival analysis showed that the 28-day survival rate of the low PLT level group was 19.0% and that of the high PLT level group was 93.1% at the node of 214.97 × 109/L, and the difference between the 2 groups was statistically significant (χ2 = 216.538, P < .001). The 28-day survival rate of the low PCT level group was 93.4% and that of the high PCT level group was 51.7% at the node of 2.85 ng/mL, and the difference between the 2 groups was statistically significant (χ2 = 63.437, P < .001). There was a negative correlation between PCT level and PLT level (r = -0.412, P < .001). Platelet combined with serum procalcitonin detection has high predictive value for judging the 28-day prognosis of sepsis, and it can be used as an index for evaluating the patient's condition and prognosis, and is worthy of clinical promotion and application.

Purpose To compare the value of endorectal ultrasonography (US) with shear-wave elastography (SWE) in staging rectal tumors before surgery. Materials and Methods This prospective study was approved by the institutional review board and written informed consent was obtained. In a pilot cohort from April 2015 to January 2016, 70 patients with rectal adenocarcinomas and/or adenomas confirmed with histopathologic examination underwent both endorectal US and SWE. Tumor stiffness and three regions of reference backgrounds, as well as tumor stiffness ratios (SRs) versus these backgrounds, were analyzed. The optimal staging feature was selected by using receiver operating characteristic analysis, and the concordance rate with pathologic stage was analyzed and compared with endorectal US. The results were validated in an independent cohort of 30 patients from February 2016 to July 2016. Results In the pilot study, from rectal adenoma to stage T3 cancers, the tumor stiffness, stiffness of peritumoral fat, tumor SR versus distant perirectal fat, and tumor SR versus normal rectal wall were significantly increased (all P < .05, correlation coefficients between SWE features and pathologic T stages were 0.589-0.853). Receiver operating characteristic analysis of tumor staging demonstrated that tumor stiffness was the optimal feature with the highest area under the receiver operating characteristic curve (AUC = 0.991-1.000). The cutoff values of stage T1, T2, and T3 cancers were 26.9 kPa, 70.3 kPa, and 112.0 kPa, respectively. For SWE, the diagnostic concordance rate with pathologic stage (95.7%, weighted κ = 0.962) was higher than that of endorectal US (75.7%, weighted κ = 0.756). In the validation cohort, similar findings were revealed for diagnostic concordance rate (93.3% vs 76.7%; weighted κ = 0.927 vs 0.651) and diagnostic performance of tumor staging (AUC = 0.950-1.000 vs 0.700-0.833). Conclusion By using the feature of tumor stiffness at SWE, the accuracy of preoperative staging for rectal tumors was improved compared with endorectal US in the pilot study, but was not significantly different in the validation cohort, potentially due to small sample size. © RSNA, 2017 Online supplemental material is available for this article.

OBJECTIVE: To study the weak loop in the treatment of children with out-of-hospital cardiac arrest (OHCA) and the treatment strategy for improvement. METHOD: Data of a total of 133 patients with OHCA who were rescued by Wuxi pre-hospital care center during the 2005 - 2011 were analyzed. RESULT: The main causes of pediatric OHCA were drowning (52/133) and accidental injury disease (30/133). The cases of OHCA were mainly located in public places (60/133) and the majority occurred in winter and summer. The emergency rescue response time was (13.21 ± 8.09) min, the rate of first witness treatment was 3.91%, intubations was performed in 11.11%, opening of vein access was 23.15% and one case got restoration of spontaneous circulation (ROSC). CONCLUSION: The rate of ROSC of pre-hospital cardiac arrest in children was significantly lower than that of hospital cardiac arrest. Preventive interventions on children's accidents and the skills of pre-hospital staff on pediatric advanced life support (PALS) need to be urgently improved.
