OBJECTIVETo investigate the clinical effects of bone setting manipulation on simplified operation and swelling reduction in treating calcaneal fractures.

METHODSFrom December 2005 to November 2010, 42 patients with calcaneal were reviewed, including 25 males and 17 females, ranging in age from 18 to 74 years, with an average of 41.4 years. Twenty patients had fractures in the left and 22 in the right. Twenty-three patients were treated with anatomical plate fixation, 19 patients were treated with Kirchners wires or cannulated screws fixation. The average period of swelling in soft tissue, joint function and complications were evaluated.

RESULTSForty-two patients were followed up, and the duration ranged from 3 to 18 months, with a mean of 8.3 months. The pain was markedly relieved at the next day after reduction, and the swelling was relieved in 3 to 5 days. The operative was simplified and the average operative time was 90 minutes. The swelling was relieved in 4 to 7 days after the operation, and the necrosis of skin was not found. The average postoperatively Böhler angle was (31 +/- 3.2) degrees. Gissane angle was (112 +/- 5.3) degrees. Calcaneal width was (30.2 +/- 0.89) mm. According to Maryland foot function score system, 16 patients got an excellent result, 18 good, 6 fair and 2 bad.

CONCLUSIONThe operation is simplified, and skin complications decrease, as well as the detumescence period is shortened.

Objective To establish a Nomogram predictive model for Neonatal Sepsis(NS)based on the general characteristics and initial complete blood count of neonates.Methods Retrospective analysis was conducted on the clinical data of newborns who were admitted for the first time to NICU and completed blood routine examination after admission in the MIMIC Ⅲ database.The LASSO-Logistic regression was used to investigate the prediction factors of NS,and then Nomogram prediction model was established.Internal validation was performed using boot-strap resampling with 1000 iterations.External validation of the model was performed using the data from newborns admitted to the First Affiliated Hospital of Zhengzhou University.We evaluated the predictive performance by Area Under the Receiver Operating Characteristic Curve(AUROC),C-index,calibration curve,and decision curve analysis(DCA).Results Among the 3,001 neonates,185 were diagnosed with NS.The Nomogram model was con-structed based on indicators such as respiratory distress syndrome,gestational age,birthweight,and initial hemato-logical parameters(red blood cell count,white blood cell count,lymphocyte percentage,neutrophil percentage),exhibiting good predictive performance with an AUROC of 0.860.Satisfactory predictive abilities were confirmed through both internal and external validation.Conclusion This study developed and validated a well-performing Nomogram prediction model.With simple parameters,it can help clinicians identify newborns at high risk early.
