IntroductionClinical decision support tools capable of predicting which patients are at highest risk for venous thromboembolism (VTE) can assist in guiding surveillance and prophylaxis decisions. The Trauma Embolic Scoring System (TESS) has been shown to model VTE risk in civilian trauma patients. No such support tools have yet been described in combat casualties, who have a high incidence of VTE. The purpose of this study was to evaluate the utility of TESS in predicting VTE in military trauma patients.MethodsA retrospective cohort study of 549 combat casualties from October 2010 to November 2012 admitted to a military treatment facility in the USA was performed. TESS scores were calculated through data obtained from the Department of Defense Trauma Registry and chart reviews. Univariate analysis and multivariate logistic regression were performed to evaluate risk factors for VTE. Receiver operating characteristic (ROC) curve analysis of TESS in military trauma patients was also performed.ResultsThe incidence of VTE was 21.7% (119/549). The median TESS for patients without VTE was 8 (IQR 4–9), and the median TESS for those with VTE was 10 (IQR 9–11). On multivariate analysis, Injury Severity Score (ISS) (OR 1.03, p=0.007), ventilator days (OR 1.05, p=0.02), and administration of tranexamic acid (TXA) (OR 1.89, p=0.03) were found to be independent risk factors for development of VTE. On ROC analysis, an optimal high-risk cut-off value for TESS was ≥7 with a sensitivity of 0.92 and a specificity of 0.53 (area under the curve 0.76, 95% CI 0.72 to 0.80, p<0.0001).ConclusionsWhen used to predict VTE in military trauma, TESS shows moderate discrimination and is well calibrated. An optimal high-risk cut-off value of ≥7 demonstrates high sensitivity in predicting VTE. In addition to ISS and ventilator days, TXA administration is an independent risk factor for VTE development.Level of evidenceLevel III.

Serial venous duplex scans (VDS) were done in 507 trauma patients with at least one risk factor (RF) for venous thromboembolism (VTE) during a 2-year study period. Deep vein thrombosis (DVT) was detected in 31 (6.1%) patients. This incidence was 3.1 per cent in low (1–2 RFs), 3.4 per cent in moderate (3–5 RFs), and 7.7 per cent in high (≥6 RFs) VTE scores ( P = 0.172). Incidence was statistically different (3% vs 7.2%, P = 0.048) on reanalyzing patients in two risk categories, low-risk (1–4 RFs) and high-risk (≥5 RFs). Only 4 of 16 RFs had statistically higher incidence of DVT in patients with or without RFs: previous VTE (27.3% vs 5.6%, odds ratio (OR) 6.628, P = 0.024), spinal cord injury (22.6% vs 5%, OR 5.493, P = 0.001), pelvic fractures (11.4% vs 5.1%, OR 2.373, P = 0.042), and head injury with a greater than two Abbreviated Injury Score (10.5% vs 4.2%, OR 2.639, P = 0.014). On reanalyzing patients with ≥5 RFs vs <5RFs, obesity (14.3 vs 6.1%, P = 0.007), malignancy (5.6% vs 0.6%, P = 0.006), coagulopathy (10.8% vs 1.8%, P = 0.000), and previous VTE (3.2% vs 0%, P = 0.019) were significant on univariate analysis. Patients with DVT had 3.70 ± 1.75 RFs and a 9.61 ± 4.93 VTE score, whereas, patients without DVT had 2.66 ± 1.50 RFs and a 6.83 ± 3.91 VTE score ( P = 0.000). DVTs had a direct positive relationship with higher VTE scores, length of stay, and number of VDS (>1 r, P ≤ 0.001). Increasing age was a weak risk factor (0.03 r, P = 0.5). First two VDS diagnosed 77 per cent of DVTs. Patients with injury severity score of ≥15 and 25 had higher DVTs compared with the ones with lower injury severity score levels ( P ≤ 0.05). Pulmonary embolism was silent in 63 per cent and DVTs were asymptomatic in 68 per cent.

BackgroundDelirium has been shown to prolong the length of intensive care unit stay, hospitalization, and duration of ventilatory control, in addition to increasing the use of sedatives and increasing the medical costs. Although there have been a number of reports referring to risk factors for the development of delirium, no model has been developed to predict delirium in trauma patients at the time of admission. This study aimed to create a scoring system that predicts delirium in trauma patients.MethodsIn this single-center, retrospective, observational study, trauma patients aged 18 years and older requiring hospitalization more than 48 hours were included and divided into the development and validation cohorts. Univariate analysis was performed in the development cohort to identify factors significantly associated with prediction of delirium. The final scoring system for predicting delirium was developed using multivariate analysis and internal validation was performed.ResultsOf the 308 patients in the development cohort, 91 developed delirium. Clinical Frailty Score, fibrin/fibrinogen degradation products, low body mass index, lactate level, and Glasgow Coma Scale score were independently associated with the development of delirium. We developed a scoring system using these factors and calculated the delirium predictive score, which had an area under the curve of 0.85. In the validation cohort, 46 of 206 patients developed delirium. The area under the curve for the validation cohort was 0.86, and the calibration plot analysis revealed the scoring system was well calibrated in the validation cohort.DiscussionThis scoring system for predicting delirium in trauma patients consists of only five risk factors. Delirium prediction at the time of admission may be useful in clinical practice.Level of evidencePrognostic and epidemiological, level III.

AbstractTrauma-induced coagulopathy (TIC) is well documented in injured children. However, many important features of pediatric hemostasis are still in development in early childhood and may impact TIC. Certain pediatric subgroups are at a higher risk. Traumatic brain injury, which occurs with a higher rate in children, and physical child abuse are known risk factors for TIC that deserve special consideration. Resuscitation of a pediatric trauma patient follows many of the same goals as in the injured adult trauma, although some key aspects of pediatric resuscitation require ongoing investigation. Venous thromboembolism occurs with higher rates in certain high-risk groups of pediatric trauma patients, although overall it is considerably less frequent in children as compared with adults.

Abstract Complications during induction chemotherapy (CT) for AML cause mortality in 5–20% of cases. It is relevant to define the risk of early death in this setting. In patients with a high probability of dying due to toxicity, the intensification of the supportive measures and/or alternative antineoplastic approaches could be appropriate. The aim of this study was to detect the features associated with lethal complications during induction CT for AML. We defined early deaths (ED) as those occurring before 42 days after the start of induction in the absence of evident leukemia. We analyzed all consecutive patients diagnosed with AML between June 1998 and February 2006 in 20 Spanish hospitals. These cases were treated according two multicenter trials CETLAM 99 (n=326) and CETLAM 2003 (n=248). Both schemes included idarubicin 12 mg/m2 days 1,3 and 5, etoposide 100 mg/m2 days 1–3 and cytarabine 500 mg/m2/12 hours days 1, 3, 5 and 7 as front-line treatment. In the CETLAM 2003, G-CSF (150 mg/m2 days 0–7) was added as priming therapy. The series included 574 patients, 248 (43%) female, with a median age of 48 years. Creatinine level was elevated (> 1,2 mg/dL) in 11% of patients. The overall mortality rate during induction (ED) was 12% (n=69). 335 (58%) patients achieved a complete remission with a single course of CT, 108 (19%) a partial remission and 62 (11%) were refractory. The most common causes of death were infection (n= 28, 46%), bleeding (n=7, 11%), pulmonary failure not due to infection (n=6, 10%), and multiorgan failure (n=4, 7%). Univariate analysis showed that age older than 50 years old, male gender, M4 or M5 FAB subtype, leukocyte count higher than 100x109/L, blasts in the marrow >70% and creatinine level above 1,2 mg/dL were associated with more frequent ED. In multivariate analysis, elevated creatinine level [hazard ratio (HR) 2.6 (1.3–5.2); P=0.009], leukocytosis >100x109/L [HR 2.3 (1.1–4.6) P=0.021] and age > 50 years old [HR 2.1 (1.4–3.9) P=0.018] were independent risk factors. The remaining parameters, including among others the use of G-CSF, gender, blasts in the marrow, treatment protocol, cytogenetics at diagnosis and FLT-3 mutational status were not associated with higher incidence of ED. Taking into account the three significant variables identified as risk factors, we developed a scoring system to predict the probability of ED during induction. The probability of ED in the low risk (none risk factor, n=212), intermediate risk (1 risk factor, n=239) and high risk (2 or 3 risk factors, n=57) categories were 3%, 11% and 28% respectively (P<0.001). The HR of ED for patients in the intermediate and high risk groups were 3.6 (1.5–8.1, P=0.003) and 7.9 (3.1–19.7; P<0.001) as compared with the low risk group. In conclusion, impaired kidney function, advanced age and hyperleukocytosis are the relevant variables increasing mortality during induction CT for AML. With these three factors it is possible to define a scoring system which predicts the probability of ED. A different approach for patients in the high-risk group should be investigated.

Venous thromboembolism (VTE) is a significant cause of mortality in patients with lung cancer. Despite the availability of a wide range of anticoagulants to help prevent thrombosis, thromboprophylaxis in ambulatory patients is a challenge due to its associated risk of haemorrhage. As a result, anticoagulation is only recommended in patients with a relatively high risk of VTE. Efforts have been made to develop predictive models for VTE risk assessment in cancer patients, but the availability of a reliable predictive model for ambulate patients with lung cancer is unclear. We have analysed the latest information on this topic, with a focus on the lung cancer-related risk factors for VTE, and risk prediction models developed and validated in this group of patients. The existing risk models, such as the Khorana score, the PROTECHT score and the CONKO score, have shown poor performance in external validations, failing to identify many high-risk individuals. Some of the newly developed and updated models may be promising, but their further validation is needed.

ObjectivesTo evaluate the significance of adenosquamous carcinoma (ASC) compared with adenocarcinoma (AC) in the survival of surgically treated early-stage cervical cancer.MethodsWe retrospectively reviewed the medical records of 163 patients with International Federation of Gynecology and Obstetrics stage IA2 to stage IIB cervical cancer who had been treated with radical hysterectomy with or without adjuvant radiotherapy between January 1998 and December 2008. The patients were classified according to the following: (1) histological subtype (ASC group or AC group) and (2) pathological risk factors (low-risk or intermediate/high-risk group). Survival was evaluated using the Kaplan-Meier method and compared using the log-rank test. Multivariate analysis of progression-free survival (PFS) was performed using the Cox proportional hazards regression model to investigate the prognostic significance of histological subtype.ResultsClinicopathological characteristics were similar between the ASC and AC histology groups. Patients with the ASC histology displayed a PFS rate similar to that of the patients with the AC histology in both the low-risk and intermediate/high-risk groups. Neither the recurrence rate nor the pattern of recurrence differed between the ASC group and the AC group. Univariate analysis revealed that patients with pelvic lymph node metastasis and parametrial invasion achieved significantly shorter PFS than those without these risk factors.ConclusionsCharacteristics of the patients and the tumors as well as survival outcomes of ASC were comparable to adenocarcinoma of early-stage uterine cervix treated with radical hysterectomy. Our results in part support that the management of ASC could be the same as the one of AC of the uterine cervix.

Gestational Trophoblastic Neoplasia

This study was designed to analyze the outcomes of chemotherapy for high-risk gestational trophoblastic neoplasia (GTN) with EMA-CO regimen as primary and secondary protocol in China. Fifty-four patients with high-risk GTN received 292 EMA/CO treatment cycles between 1996 and 2005. Forty-five patients were primarily treated with EMA-CO, and nine were secondarily treated after failure to other combination chemotherapy. Adjuvant surgery and radiotherapy were used in the selected patients. Response, survival and related risk factors, as well as chemotherapy complications, were retrospectively analyzed. Thirty-five of forty-five patients (77.8%) receiving EMA-CO as first-line treatment achieved complete remission, and 77.8% (7/9) as secondary treatment. The overall survival rate was 87.0% in all high-risk GTN patients, with 93.3% (42/45) as primary therapy and 55.6% (5/9) as secondary therapy. The survival rates were significantly different between two groups (χ2= 6.434, P = 0.011). Univariate analysis showed that the metastatic site and the number of metastatic organs were significant risk factors, but binomial distribution logistic regression analysis revealed that only the number of metastatic organs was an independent risk factor for the survival rate. No life-threatening toxicity and secondary malignancy were found. EMA-EP regimen was used for ten patients who were resistant to EMA-CO and three who relapsed after EMA-CO. Of those, 11 patients (84.6%) achieved complete remission. We conclude that EMA-CO regimen is an effective and safe primary therapy for high-risk GTN, but not an appropriate second-line protocol. The number of metastatic organs is an independent prognostic factor for the patient with high-risk GTN. EMA-EP regimen is a highly effective salvage therapy for those failing to EMA-CO.
