This paper aimed to explore the application value of CT imaging in the correlation analysis of communicating hydrocephalus (CH) after decompressive craniectomy (DC) of craniocerebral injury (CI). 410 patients with craniocerebral trauma who were admitted to the hospital from October 2015 to October 2019 were taken as subjects, among which 130 patients suffered from CH. All patients underwent craniocerebral CT examination, and logistic regression was applied to analyze the risk factors of hydrocephalus in CI and hydrocephalus after DC surgery. The results showed that the coma time (OR = 5.1283, P = 0.001 ), subarachnoid hemorrhage (SAH) (OR = 7.6543, P = 0.020 ), Glasgow Coma Scale (GCS) score no more than 8 points (OR = 3.5480, P = 0.001 ), intraventricular hemorrhage (OR = 2.2653, P = 0.003 ), cerebral contusion and laceration (OR = 1.036, P = 0.002 ), and subdural hemorrhage (OR = 2.4376, P = 0.001 ) were independent risk factors for CH. Bilateral DC (OR = 15.342, P = 0.023 ), second surgery (OR = 7.021, P = 0.004 ), bone window height (OR = 6.543, P = 0.041 ), and bone window area (OR = 1.035, P = 0.012 ) were independent risk factors for CH after DC surgery. It suggested that CT imaging technology could be utilized in the diagnosis of CI. The risk factors of CH included coma time, SAH, GCS score no more than 8, intraventricular hemorrhage, brain contusion, subdural hematoma, bilateral DC, bone window height, bone window area, and second surgery.

Object Decompressive craniectomy is a life-saving measure for patients who have sustained traumatic brain injury (TBI), but patients undergoing this procedure may still die during an early phase of head injury. The aim of this study was to investigate the incidence, causes, and risk factors of 30-day mortality in traumatically brain-injured patients undergoing decompressive craniectomy. Methods The authors included 201 head-injured patients undergoing decompressive craniectomy in this 3-year retrospective study. The main outcome evaluated was 30-day mortality in patients who had undergone craniectomy after TBI. Demographic and clinical data, including information on death, were obtained for subsequent analysis. The authors identified differences between survivors and nonsurvivors in terms of clinical parameters; multivariate logistic regression was used to adjust for independent risk factors of short-term death. Results The 30-day mortality rate was 26.4% in traumatically brain-injured patients undergoing decompressive craniectomy. The majority of deaths following decompression resulted from uncontrollable brain swelling and extensive brain infarction, which accounted for 79.2% of mortality. In the multivariate logistic regression mode, the 2 independent risk factors for 30-day mortality were age (OR 1.035 [95% CI 1.006–1.064]; p = 0.018) and Glasgow Coma Scale (GCS) score before decompressive craniectomy (OR 0.769 [95% CI 0.597–0.990]; p = 0.041). Conclusions There is a high 30-day mortality rate in traumatically brain-injured patients undergoing decompressive craniectomy. Most of the deaths are attributed to ongoing brain damage, even after decompression. Risk factors of short-term death, including age and preoperative GCS score, are important in patient selection for decompressive craniectomy, and these factors should be considered together to ensure the highest chance of surviving TBI.

Purpose: The objective of this study was to determine the independent risk factors associated with peripheral venous catheter (PVC) failure and develop a model that can predict PVC failure. Methods: This prospective, multicenter cohort study was carried out in nine tertiary hospitals in Suzhou, China between December 2017 and February 2018. Adult patients undergoing first-time insertion of a PVC were observed from catheter insertion to removal. Logistic regression was used to identify the independent risk factors predicting PVC failure. Results: This study included 5345 patients. The PVC failure rate was 54.05% ( n = 2889/5345), and the most common causes of PVC failure were phlebitis (16.3%) and infiltration/extravasation (13.8%). On multivariate analysis, age (45–59 years: OR, 1.295; 95% CI, 1.074–1.561; 60–74 years: OR, 1.375; 95% CI, 1.143–1.654; ⩾75 years: OR, 1.676; 95% CI, 1.355–2.073); department (surgery OR, 1.229; 95% CI, 1.062–1.423; emergency internal/surgical ward OR, 1.451; 95% CI, 1.082–1.945); history of venous puncture in the last week (OR, 1.298, 95% CI 1.130–1.491); insertion site, number of puncture attempts, irritant fluid infusion, daily infusion time, daily infusion volume, and type of sealing liquid were independent predictors of PVC failure. Receiver operating characteristic curve analysis indicated that a logistic regression model constructed using these variables had moderate accuracy for the prediction of PVC failure (area under the curve, 0.781). The Hosmer-Lemeshow goodness of fit test demonstrated that the model was correctly specified (χ2 = 2.514, p = 0.961). Conclusion: This study should raise awareness among healthcare providers of the risk factors for PVC failure. We recommend that healthcare providers use vascular access device selection tools to select a clinically appropriate device and for the timely detection of complications, and have a list of drugs classified as irritants or vesicants so they can monitor patients receiving fluid infusions containing these drugs more frequently.

Background: Intracerebral hemorrhage (ICH) has the highest short and long-term morbidity and mortality rates of stroke subtypes. While increased intracranial pressure due to the presence of intraventricular hemorrhage (IVH) may relate to early poor outcomes, the mechanism of reduced 3-month outcome with IVH is unclear. We hypothesized that IVH may cause symptoms similar to normal pressure hydrocephalus (NPH), specifically urinary incontinence and gait disturbance. Methods: We used interviewed cases from the Genetic and Environmental Risk Factors for Hemorrhagic Stroke Study (7/1/08-12/31/12) that had 3-month follow-ups available. CT images were analyzed for ICH volume and location, and IVH presence and volume. Incontinence and dysmobility were defined by Barthel Index at 3 months. We chose a Barthel Index score of bladder less than 10 and mobility less than 15 to define incontinence and dysmobility, respectively. Multivariate analysis was used to assess independent risk factors for incontinence and dysmobility. ICH and IVH volumes were log transformed because of non-normal distributions. Results: Barthel Index was recorded for 308 ICH subjects, of whom 106 (34.4%) had IVH. Presence of IVH was independently associated with both incontinence (OR 2.7; 95% CI 1.4-5.2; p=.003) and dysmobility (OR 2.5; 95% CI 1.4-4.8; p=.003). The Table shows that increasing IVH volume was also independently associated with both incontinence and dysmobility after controlling for ICH location, ICH volume, age, baseline mRS, and admission GCS. Conclusion: Our data show that patients with IVH after ICH are at an increased risk for developing the NPH-like symptoms of incontinence and dysmobility. This may explain the worse long-term outcomes of patients who survive ICH with IVH than those who had ICH alone. Future studies are needed to confirm this finding, and to determine the effect of IVH interventions such as shunt or intraventricular thrombolysis.

Background. The predictive values of monocytes in the prognosis of patients with acute paraquat (PQ) poisoning are unclear. This retrospective study investigated the predictive values of monocytes in the prognosis of patients with acute PQ poisoning. Methods. Adult patients who suffered from acute PQ poisoning in the emergency care unit of Cangzhou Central Hospital from May 2012 to December 2018 were enrolled. The patients were divided into groups, namely, survival and nonsurvival, according to a 90-day prognosis. Moreover, correlation, logistic regression, receiver-operator characteristic (ROC), and Kaplan–Meier curve analyses were applied to evaluate the monocyte values used to predict the prognosis of patients with acute PQ poisoning. Result. Among the 109 patients, 45 survived within 90 days after the poisoning, resulting in a 41.28% survival rate. The monocyte count of the nonsurvivors was significantly higher than that of the survivors (P< 0.001). Correlation analysis showed that monocyte count positively correlated with plasma PQ concentration (r= 0.413; P< 0.001) and negatively correlated with survival time (r= 0.512; P< 0.001) and 90-day survival (r= 0.503; P< 0.001). Logistic regression analysis showed that elevated monocytes were the independent risk factors for the 90-day survival. The area under the ROC curve of the monocyte count used to predict the 90-day survival was 0.826 (95% CI: 0.751–0.904), the optimal cut-off was 0.51×109/L, sensitivity was 73.4%, and specificity was 86.7%. Conclusion. This study demonstrated that elevated monocyte count is a useful early predictor of 90-day survival in patients with acute PQ poisoning. However, further studies are warranted to draw firm conclusions.

Purpose: To detect lung metastases, we conducted a retrospective study to improve patient prognosis.Methods: Hypertension patients with ocular metastases (OM group; n = 58) and without metastases (NM group; n = 1,217) were selected from individuals with lung cancer admitted to our hospital from April 2005 to October 2019. The clinical characteristics were compared by Student's t-test and chi-square test. Independent risk factors were identified by binary logistic regression, and their diagnostic value evaluated by receiver operating characteristic curve analysis.Results: Age and sex did not differ significantly between OM and NM groups; There were significant differences in pathological type and treatment. Adenocarcinoma was the main pathological type in the OM group (67.24%), while squamous cell carcinoma was the largest proportion (46.43%) in the NM group, followed by adenocarcinoma (34.10%). The OM group were treated with chemotherapy (55.17%), while the NM group received both chemotherapy (39.93%) and surgical treatment (37.06%). Significant differences were detected in the concentrations of cancer antigen (CA)−125, CA-199, CA-153, alpha fetoprotein (AFP), carcinoembryonic antigen (CEA), cytokeratin fraction 21-1 (CYFRA21-1), total prostate-specific antigen, alkaline phosphatase, and hemoglobin (Student's t-test). Binary logistic regression analysis indicated that CA-199, CA-153, AFP, CEA, and CYRFA21-1 were independent risk factors for lung cancer metastasis. AFP (98.3%) and CEA (89.3%) exhibited the highest sensitivity and specificity, respectively, while CYRFA21-1 had the highest area under the ROC curve value (0.875), with sensitivity and specificity values of 77.6 and 87.0%, respectively. Hence, CYFRA21-1 had the best diagnostic value.

Abstract Background Postoperative ischemic stroke is a devastating complication following total hip arthroplasty (THA). The purpose of the current study was to investigate the incidence of postoperative acute ischemic stroke (AIS) in patients ≥70 years old with THA for hip fracture after 90 days and independent risk factors associated with 90-day AIS. Methods A multicenter retrospective study was conducted, patients ≥70 years old with THA for hip fracture under general anesthesia were included from February 2017 to March 2020. Patients with AIS within 90 days after THA were identified as AIS group; patients with no AIS were identified as no AIS group. The baseline characteristics and risk factors were collected, multivariable logistic regression was used to identify independent risk factors of 90-dayAIS. Results: 2517 patients (mean age 76.18 ± 6.01) were eligible for inclusion in the study. 2.50% (63/2517) of patients had 90-day AIS. Compared with no AIS, older age, diabetes, hyperlipidemia, atrial fibrillation (AF) and higher D-dimer value were more likely in patients with AIS (P < 0.05), and anticoagulant use was fewer in patients with AIS. ROC curve analysis showed that the optimal cut point of D-dimer for AIS was D-dimer≥4.12 μg/ml. Multivariate logistic regression analysis showed that D-dimer≥4.12 μg/ml [adjusted odds ratio (aOR), 4.44; confidence interval (CI), 2.50–7.72; P < 0.001], older age (aOR, 1.08; 95%CI, 1.03–1.12; P < 0.001), hyperlipidemia (aOR, 2.28; 95%CI, 1.25–4.16; P = 0.007), atrial fibrillation (aOR, 5.84; 95% CI, 1.08–15.68; P = 0.001), and diabetes (aOR, 2.60; 95% CI, 1.56–4.39; P < 0.001) were associated with increased risk of 90-day AIS after THA. Conclusions In conclusion, we found that the incidence of 90-day AIS in patients≥70 years old with THA for hip fracture was 2.5%. Older age, diabetes, hyperlipidemia, AF and higher D-dimer value were independent risk factors for 90-day AIS in patients≥70 years old with THA for hip fracture.

Background: Hypotensive bradycardic events (HBEs) are a frequent adverse event in patients who underwent shoulder arthroscopic surgery under interscalene block (ISB) in the sitting position. This retrospective study was conducted to investigate the independent risk factors of HBEs in shoulder arthroscopic surgery under ISB in the sitting position. Methods: A total of 2549 patients who underwent shoulder arthroscopic surgery under ISB and had complete clinical data were included in the study. The 357 patients who developed HBEs were included in the HBEs group, and the remaining 2192 in the non-HBEs group. The potential risk factors for HBEs, such as age, sex, past medical history, anesthetic characteristics, and intraoperative medications were collected and compared between the groups. Statistically significant variables were included in a logistic regression model to further evaluate the independent risk factors for HBEs in shoulder arthroscopic surgery under ISB. Results: The incidence of HBEs was 14.0% (357/2549). Logistic regression analysis revealed that the intraoperative use of hydralazine (odds ratio [OR] 4.2; 95% confidence interval [CI] 2.9–6.3), propofol (OR 2.1; 95% CI 1.3–3.6), and dexmedetomidine (OR 3.9; 95% CI 1.9–7.8) before HBEs were independent risk factors for HBEs in patients who received shoulder arthroscopic surgery under ISB. Conclusions: The intraoperative use of antihypertensives such as hydralazine and sedatives such as propofol or dexmedetomidine leads to increased risk of HBEs during shoulder arthroscopic surgery under ISB in the sitting position.

Abstract Background There are few studies on the development and effect of coagulopathy in patients with a traumatic brain injury (TBI) during the early post-operative period. We determined the risk factors and neurologic outcomes of in patients with a TBI and coagulopathy diagnosed by routine laboratory tests within 72 hours post-operatively. Methods The baseline characteristics, intra-operative management, and follow-up results of 462 patients with TBIs were obtained and retrospectively analyzed by multivariate logistic regression from January 2015 to June 2019. Coagulopathy was defined as an activated partial thromboplastin time > 40 seconds, international normalized ratio >1.4, or a platelet count < 100×109 /L.Results Multivariate logistic regression analysis revealed that the Glasgow Coma Scale (GCS) at the time of admission, Injury Severity Score (ISS) at the time of admission, pupil mydriasis, duration of surgery, intra-operative blood loss, and intra-operative crystalloid resuscitation were independent risk factors for patients who developed a coagulopathy post-operatively. There were statistical differences in mortality (p = 0.049), the Glasgow Outcome Scale-Extended (GCS-E; p = 0.024), and the modified Rankin Scale (p = 0.043) between patients with and without coagulopathy 1 week after surgery. Coagulopathy within 72 h after surgery revealed a trend for higher mortality at 1 week (66.7%), 3 months (71.4%), and 6 months (76.2%). Furthermore, coagulopathy and contusion expansion in the early post-operative period were independent risk factors for TBI mortality after surgery. Intra-operative crystalloid resuscitation had a substantial diagnostic accuracy in predicting coagulopathy within 72 h post-operatively (area under the curve [AUC] = 0.972).Conclusion Coagulopathy within 72 h post-operatively in patients with a TBI predicted worse disease progression and unfavorable neurologic outcomes. Hence, we should take practical and reasonable measures to manage these risk factors, which may protect patients with a TBI from post-operative coagulopathy.

Abstract Background: This study aimed to investigate potential predictors, including cerebroplacental ratio (CPR), middle cerebral artery (MCA)/uterine artery pulsatility index (PI) ratio, for adverse perinatal outcome in pregnancies at term.Methods: This was an observational, prospective study of recruited pregnancies at term. An adverse perinatal outcome was set as the primary observational endpoint. The receiver operating characteristic (ROC) curve was plotted to investigate the predictive and cut-off values of risk factors for adverse perinatal outcome. Independent risk factors (maternal, neonatal, prenatal ultrasound and Doppler variables) for adverse perinatal outcome were evaluated by the univariate and multivariate logistic regression analyses.Results: A total of 392 pregnancies at term were included and 19.4% of them had suffered adverse perinatal outcome. CPR (OR: 0.42, 95%CI: 0.20-0.93, P=0.032) and MCA/uterine artery PI ratio (OR: 0.25, 95%CI: 0.16-0.42, P=0.032) were two independent risk factors for adverse perinatal outcome by univariate and multivariate logistic regression analyses.Conclusions: MCA/uterine artery PI ratio is a good predictor of adverse perinatal outcome in pregnancies at term.

The aim of this study was to analyze risk factors for postoperative urinary tract infection (UTI) and urinary retention (UR) in patients with colorectal cancer. Using Nationwide Inpatient Sample 2006–2009, a retrospective analysis of surgical patients with colorectal cancer was conducted. Patients were stratified into groups, with or without UTI/UR. The LASSO algorithm for logistic regression identified independent risk factors. A total of 93,931 surgical patients with colorectal cancer were identified. The incidences of UTI and UR were 5.91 and 2.52 per cent, respectively. Overall in-hospital mortality was 2.68 per cent. The UTI group demonstrated significantly higher in-hospital mortality rates compared with those without. Both UTI and UR groups were associated with prolonged hospital stay and increased hospital charge. Multivariate logistic regression analysis revealed age older than 60 years, females, anemia, congestive heart failure, coagulopathy, diabetes with chronic complications, fluid and electrolyte, paralysis, pulmonary circulation disorders, renal failure, and weight loss were independent risk factors of UTI. Age older than 60 years, male gender, rectal and rectosigmoid cancers, and postoperative anastomotic leakage and ileus were independent risk factors for UR. Postoperative UTI increases in-house mortality. Postoperative UTI/UR in patients with colorectal cancer increases length of stay and hospital charges. Knowledge of these specific risk factors for UTI and UR is needed to counsel patients and prevent these complications in this high-risk population.
