Incidence and risk factors of preoperative venous thromboembolism in patients with malignant musculoskeletal tumors: an analysis based on D-dimer screening and imaging

Abstract Background: Venous thromboembolism (VTE) is a major complication in patients with malignant tumors and orthopedic disorders. Although it is known that patients undergoing surgery for orthopedic oncology are at an increased risk of thromboembolic events, only few studies have investigated this risk in detail. Therefore, the aim of this study was to determine the incidence and risk factors for preoperative VTE in orthopedic oncology patients.Methods: We retrospectively reviewed the medical records of 270 patients who underwent surgical procedures, including biopsy for orthopedic oncology, have undergone measurements of preoperative D-dimer levels, and were subsequently screened for VTE by lower extremity venous ultrasonography and/or contrast-enhanced computed tomography scans. Statistical analyses were performed to examine the incidence and risk factors for VTE. Receiver operating characteristic (ROC) analysis was performed to verify the D-dimer cutoff value for the diagnosis of VTE.Results: Overall, 199 patients (103 with primary soft tissue sarcomas, 38 with primary bone sarcomas, 46 with metastatic tumors, and 12 with hematologic malignancies) were included. D-dimer levels were high in 79 patients; VTE was detected in 19 patients (9.5%). Multivariate analysis indicated that age ≥60 years (P = 0.021) and tumor location in the lower limbs (P = 0.048) were independent risk factors for VTE. ROC analysis showed that the D-dimer cutoff value for the diagnosis of VTE was 1.53 µg/mL; the sensitivity and specificity were 89.5% and 79.4%, respectively.Conclusions: Our study indicated that age and tumor location in the lower limbs were independent risk factors for preoperative VTE in orthopedic oncology patients. D-dimer levels were not associated with VTE in the multivariate analysis, likely because they are affected by a wide variety of conditions, such as malignancy and aging. Patients with high D-dimer levels and the identified risk factors are at an increased risk of preoperative VTE, and additional ultrasonography should be considered.Trial registration: Our study was approved by the institutional review board. The registration number is B200600056. The registration date was July 13, 2020.

Abstract Background: Venous thromboembolism (VTE) is known as one of the major complications in patients with malignant tumors and orthopedic disorders. Patients undergoing surgery for orthopedic oncology are at an increased risk for thromboembolic events. However, there are limited studies regarding the incidence and risk factors for preoperative VTE in orthopedic oncology patients.Methods: The aim is to determine the incidence and risk factors of preoperative VTE by screening with D-dimer. We retrospectively reviewed the medical records of 270 patients who underwent surgical procedures, including biopsy for orthopedic oncology, had preoperative D-dimer levels measured and were subsequently screened for VTE by lower extremity venous ultrasonography and contrast-enhanced computed tomography (CT) scans if necessary. Statistical analyses were performed to examine the incidence and risk factors for VTE. Receiver operating characteristic (ROC) analysis was performed to verify the cutoff value of D-dimer for the diagnosis of VTE.Results: A total of 199 patients (103 with primary soft tissue sarcomas, 38 with primary bone sarcomas, 46 with metastatic tumors and 12 with hematologic malignancies) were included. The value of D-dimer was high in 79 patients. VTE was detected in 19 patients (9.5%).

ROC analysis showed that the cutoff value of D-dimer for the diagnosis of VTE was 1.53 µg/mL (sensitivity of 89.5% and specificity of 79.4%).Conclusions: Our study indicated that age and tumor location in the lower limbs were independent risk factors for preoperative VTE in orthopedic oncology patients. D-dimer was not significantly different in the multivariate analysis because D-dimer is affected by a wide variety of conditions, such as malignancy and aging. Patients with high D-dimer levels and the abovementioned risk factors are at increased risk of preoperative VTE, and additional ultrasonography should be considered.Trial registration: Our study was approved by the institutional review board.

Postoperative Hydrocephalus

Background and aim Most patients who present with a fourth ventricle tumor have concurrent hydrocephalus, and some demonstrate persistent hydrocephalus after tumor resection. There is still no consensus on the management of hydrocephalus in patients with fourth ventricle tumor after surgery. The purpose of this study was to identify the factors that predispose to postoperative hydrocephalus and the need for a postoperative cerebrospinal fluid (CSF) diversion procedure. Materials and methods We performed a retrospective analysis of patients who underwent surgery of the fourth ventricle tumor between January 2013 and December 2018 at the Department of Neurosurgery in West China Hospital of Sichuan University. The characteristics of patients and the tumor location, tumor size, tumor histology, and preventive external ventricular drainage (EVD) that were potentially correlated with CSF circulation were evaluated in univariate and multivariate analysis. Results A total of 121 patients were enrolled in our study; 16 (12.9%) patients underwent postoperative CSF drainage. Univariate analysis revealed that superior extension (p = 0.004), preoperative hydrocephalus (p<0.001), and subtotal resection (p<0.001) were significantly associated with postoperative hydrocephalus. Multivariate analysis revealed that superior extension (p = 0.013; OR = 44.761; 95% CI 2.235–896.310) and subtotal resection (p = 0.005; OR = 0.087; 95% CI 0.016–0.473) were independent risk factors for postoperative hydrocephalus after resection of fourth ventricle tumor. Conclusion Superior tumor extension (into the aqueduct) and failed total resection of tumor were identified as independent risk factors for postoperative hydrocephalus in patients with fourth ventricle tumor.

Seizures are among the most common symptoms of meningioma. This retrospective study sought to identify risk factors for early and late seizures in meningioma patients and to evaluate a modified STAMPE2 score. In 556 patients who underwent meningioma surgery, we correlated different risk factors with the occurrence of postoperative seizures. A modified STAMPE2 score was applied. Risk factors for preoperative seizures were edema (p = 0.039) and temporal location (p = 0.038). For postoperative seizures preoperative tumor size (p < 0.001), sensomotory deficit (p = 0.004) and sphenoid wing location (p = 0.032) were independent risk factors. In terms of postoperative status epilepticus; sphenoid wing location (p = 0.022), tumor volume (p = 0.045) and preoperative seizures (p < 0.001) were independent risk factors. Postoperative seizures lead to a KPS deterioration and thus an impaired quality of life (p < 0.001). Late seizures occurred in 43% of patients with postoperative seizures. The small sub-cohort of patients (2.7%) with a STAMPE2 score of more than six points had a significantly increased risk for seizures (p < 0.001, total risk 70%). We concluded that besides distinct risk factors, high scores of the modified STAMPE2 score could estimate the risk of postoperative seizures. However, it seems not transferable to our cohort

Abstract Purpose Humans have a preference for nasal breathing during sleep. This 10-year prospective study aimed to determine if nasal symptoms can predict snoring and also if snoring can predict development of nasal symptoms. The hypothesis proposed is that nasal symptoms affect the risk of snoring 10 years later, whereas snoring does not increase the risk of developing nasal symptoms. Methods In the cohort study, Respiratory Health in Northern Europe (RHINE), a random population from Denmark, Estonia, Iceland, Norway, and Sweden, born between 1945 and 1973, was investigated by postal questionnaires in 1999–2001 (RHINE II, baseline) and in 2010–2012 (RHINE III, follow-up). The study population consisted of the participants who had answered questions on nasal symptoms such as nasal obstruction, discharge, and sneezing, and also snoring both at baseline and at follow-up (n = 10,112). Results Nasal symptoms were frequent, reported by 48% of the entire population at baseline, with snoring reported by 24%. Nasal symptoms at baseline increased the risk of snoring at follow-up (adj. OR 1.38; 95% CI 1.22–1.58) after adjusting for age, sex, BMI change between baseline and follow-up, and smoking status. Snoring at baseline was associated with an increased risk of developing nasal symptoms at follow-up (adj. OR 1.22; 95% CI 1.02–1.47). Conclusion Nasal symptoms are independent risk factors for development of snoring 10 years later, and surprisingly, snoring is a risk factor for the development of nasal symptoms.

Introduction: The prevalence of chronic kidney disease (CKD) is high among kidney neoplasm patients because of the overlapping risk factors. Our purpose is to identify kidney cancer survivors with higher CKD risk. Methods: We studied a retrospective cohort of 361 kidney tumor patients with partial or radical nephrectomy. Linear mixed model was performed. Results: Of patients with follow-up >3 months, 84% were identified retrospectively to fulfill criteria for CKD diagnosis, although CKD was documented in only 15%. Urinalysis was performed in 205 (57%) patients at the time of nephrectomy. Multivariate analysis showed interstitial fibrosis and tubular atrophy (IFTA) >25% ( p = 0.005), severe arteriolar sclerosis ( p = 0.013), female gender ( p = 0.024), older age ( p = 0.012), BMI ⩾ 25 kg/m2 ( p < 0.001), documented CKD ( p < 0.001), baseline eGFR ⩽ 60 ml/min/1.73 m2 ( p < 0.001), and radical nephrectomy ( p < 0.001) were independent risk factors of lower eGFR at baseline and during follow-up. Average eGFR decreased within 3 months post nephrectomy. However, patients with different risk levels showed different eGFR time trend pattern at longer follow-ups. Multivariate analysis of time × risk factor interaction showed BMI, radical nephrectomy and baseline eGFR had time-dependent impact. BMI ⩾ 25 kg/m2 and radical nephrectomy were associated with steeper eGFR decrease slope. In baseline eGFR > 90 ml/min/1.73 m2 group, eGFR rebounded to pre-nephrectomy levels during extended follow-up. In partial nephrectomy patients with baseline eGFR ⩾ 90 ml/min/1.73 m2 ( n = 61), proteinuria ( p < 0.001) and BMI ( p < 0.001) were independent risk factors of decreased eGFR during follow up. Conclusions: As have been suggested by others and confirmed by our study, proteinuria and CKD are greatly under-recognized. Although self-evident as a minimum workup for nephrectomy patients to include SCr, eGFR, urinalysis, and proteinuria, the need for uniform applications of this practice should be reinforced. Non-neoplastic histology evaluation is valuable and should include an estimate of global sclerosis% (GS) and IFTA%. Patients with any proteinuria and/or eGFR ⩽ 60 at the time of nephrectomy or in follow-up with urologists, and/or >25% GS or IFTA, should be referred for early nephrology consultation.

AbstractDiagnosing stroke in patients experiencing dizziness without neurological deficits is challenging for physicians. The aim of this study was to evaluate the prevalence of acute stroke in patients who presented with isolated dizziness without neurological deficits at the emergency department (ED), and determine the relevant stroke predictors in this population. This was an observational, retrospective record review of consecutive 2215 adult patients presenting with dizziness at the ED between August 2019 and February 2020. Multivariate analysis was performed to identify risk factors for acute stroke. 1239 patients were enrolled and analyzed. Acute stroke was identified in 55 of 1239 patients (4.5%); most cases (96.3%) presented as ischemic stroke with frequent involvement (29.1%) of the cerebellum. In the multivariate analysis, the history of cerebrovascular injury (odds ratio [OR] 3.08 [95% confidence interval {CI} 1.24 to 7.67]) and an age of > 65 years (OR 3.01 [95% CI 1.33 to 6.83]) were the independent risk factors for predicting acute stroke. The combination of these two risks showed a higher specificity (94.26%) than that of each factor alone. High-risk patients, such as those aged over 65 years or with a history of cerebrovascular injury, may require further neuroimaging workup in the ED to rule out stroke.

Cardiopulmonary Support System

Purpose Extracorporeal life support (ECLS) is a cardiopulmonary support system used for the treatment of severe cardiac and/or respiratory failure. Mortality is high partly because of the severity of the condition that requires support. The use of ECLS is generally associated with heavy sedation. The aim of this study was to demonstrate the feasibility of stopping sedation, allowing extubation of patients supported by ECLS. Methods 196 patients supported by ECLS for a period of 4 years were included. Sedation was stopped as soon as possible to allow extubation. The 44 extubated patients were compared with non-extubated patients. Finally, 24% of patients were not extubated without a determined cause and were compared with extubated patients. Results The extubated patients had a lower incidence of ventilator-associated pneumonia. In a multivariate analysis, the independent risk factors for death were the duration of ECLS, age and lack of extubation. Stopping sedation and extubation are feasible in selected patients under ECLS. Conclusions This strategy could be a survival factor.

AbstractThis study aimed to determine effective predictive factors for primary postpartum hemorrhage (PPH) among clinical blood parameters associated with coagulation and fibrinolysis and demographic characteristics.We retrospectively studied 1032 women who underwent determinations of clinical blood parameters at gestational week (GW) 29–32 and GW 35–37 and gave birth to singleton infants at our hospital between January 2011 and December 2013. PPH was defined as estimated blood loss ≥700 mL. Multivariate logistic regression analyses were used to determine independent risk factors and odds ratios (OR) for PPH.PPH occurred in 104 of 1032 women (10%). Three blood variables, fibrinogen level <4.0 g/L (OR [95% CI], 1.96 [1.18–3.27]), antithrombin activity <85% of normal activity level (1.84 [1.05–3.21]), and D-dimer level >2.7 μg/mL (2.03 [1.29–3.19]) at GW 35–37, and three demographic characteristics, maternal age ≥35 years (1.75 [1.15–2.68]), BMI >28.2 kg/mAmong blood parameters, higher D-dimer levels and lower levels of antithrombin activity and fibrinogen in late gestation were independent risk factors for PPH.

Poor Outcomes

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.

Facial Burn

Abstract BackgroundAfter clinical evaluation in the emergency department (ED), facial burn patients are usually intubated to protect their airways. However, the possibility of unnecessary intubation or delayed intubation after admission exists. Objective criteria for the evaluation of inhalation injury and the need for airway protection in facial burn patients are needed.MethodsFacial burn patients between January 2013 and May 2016 were reviewed. Patients who were and were not intubated in the ED were compared. All intubated patients received routine bronchoscopy to evaluate whether they had inhalation injuries. Patients with and without confirmed inhalation injuries were compared. Multivariate logistic regression analysis was used to identify the independent risk factors for inhalation injuries in facial burn patients. The reasons for intubation in patients without inhalation injuries were also investigated.ResultsDuring the study period, 121 patients were intubated in the ED among a total of 335 facial burn patients. Only 73 (60.3%) patients were later confirmed to have inhalation injuries on bronchoscopy. The comparison between patients with and without inhalation injuries showed that shortness of breath (odds ratio=3.376, p=0.027) and high total body surface area (TBSA) (odds ratio=1.038, p=0.001) were independent risk factors for inhalation injury. Other physical signs (e.g., hoarseness, burned nostril hair, etc.), laboratory examinations and chest X-ray findings were not predictive of inhalation injury in facial burn patients. All patients with a TBSA over 60% were intubated in the ED even if they did not have inhalation injuries.ConclusionIn the management of facial burn patients, positive signs on conventional physical examinations may not always be predictive of inhalation injury and the need for endotracheal tube intubation in the ED. More attention should be paid to facial burn patients with shortness of breath and a high TBSA because they have an increased risk of inhalation injuries. Airway protection is needed in facial burn patients without inhalation injuries because of their associated injuries and treatment.
