Project description:BackgroundWhile numerous studies have investigated short-term outcomes after pulmonary embolism (PE), long-term mortality remains insufficiently studied.ObjectivesTo investigate long-term outcomes in an unselected cohort of patients with PE.MethodsA total of 896 consecutive patients with PE enrolled in a single-center registry between May 2005 and December 2017 were followed up for up to 14 years. The observed mortality rate was compared with the expected rate in the general population.ResultsThe total follow-up time was 3908 patient-years (median, 3.1 years). The 1- and 5-year mortality rates were 19.7% (95% CI, 17.2%-22.4%) and 37.1% (95% CI, 33.6%-40.5%), respectively. The most frequent causes of death were cancer (28.5%), PE (19.4%), infections (13.9%), and cardiovascular events (11.6%). Late mortality (after >30 days) was more frequent than expected in the general population, a finding that was consistent in patients without cancer (the 5-year standardized mortality ratios were 2.77 [95% CI, 2.41-3.16] and 1.80 [95% CI, 1.50-2.14], respectively). Active cancer was the strongest risk factor for death between 30 days and 3 years (hazard ratio [HR], 6.51; 95% CI, 4.67-9.08) but was not associated with later mortality. Death after >3 years was predicted by age (HR, 1.86; 95% CI, 1.51-2.29 per decade), chronic heart failure (HR, 1.66; 95% CI, 1.02-2.70), and anemia (HR, 1.62; 95% CI, 1.09-2.41).ConclusionThe risk of mortality in patients with PE remained elevated compared with that in the general population throughout the follow-up period. The main driver of long-term mortality during the first 3 years was cancer. After that, mortality was predicted by age, chronic heart failure, and anemia.

Project description:BackgroundIn acute pulmonary embolism, chest computed tomography angiography derived metrics, such as the right ventricle (RV): left ventricle ratio are routinely used for risk stratification. Paucity of intraparenchymal blood vessels has previously been described, but their association with clinical biomarkers and outcomes has not been studied. We sought to determine if small vascular volumes measured on computed tomography scans were associated with an abnormal RV on echocardiography and mortality. We hypothesized that decreased small venous volume would be associated with greater RV dysfunction and increased mortality.MethodsA retrospective cohort of patients with intermediate risk pulmonary embolism admitted to Brigham and Women's Hospital between 2009 and 2017 was assembled, and clinical and radiographic data were obtained. We performed 3-dimensional reconstructions of vasculature to assess intraparenchymal vascular volumes. Statistical analyses were performed using multivariable regression and cox proportional hazards models, adjusting for age, sex, lung volume, and small arterial volume.ResultsSeven hundred twenty-two subjects were identified of whom 573 had documented echocardiography. A 50% reduction in small venous volume was associated with an increased risk of RV dilation (relative risk: 1.38 [95% CI, 1.18-1.63], P<0.001), RV dysfunction (relative risk: 1.62 [95% CI, 1.36-1.95], P<0.001), and RV strain (relative risk: 1.67 [95% CI, 1.37-2.04], P<0.001); increased cardiac biomarkers, and higher 30-day and 90-day mortality (hazard ratio: 2.50 [95% CI, 1.33-4.67], P=0.004 and hazard ratio: 1.84 [95% CI, 1.11-3.04], P=0.019, respectively).ConclusionsLoss of small venous volume quantified from computed tomography angiography is associated with increased risk of abnormal RV on echocardiography, abnormal cardiac biomarkers, and higher risk of 30- and 90-day mortality. Small venous volume may be a useful marker for assessing disease severity in acute pulmonary embolism.

Project description:BackgroundPulmonary infarction (PI) is an uncommon complication of pulmonary embolism (PE). The risk factors of PI are still relatively unclear.MethodsThis was a single-center retrospective review conducted on 500 patients with PE. After applying the inclusion and exclusion criteria, 386 patients diagnosed with PE were enrolled in our study. These patients were then categorized into the PI group (n=64) and the non-PI group (n=322). A comparison was conducted between the two groups regarding the clinical characteristics.ResultsThe occurrence of PI secondary to PE was 16.58%. In univariate analysis, recent trauma (21.9% vs. 9.9%, P=0.007), pleuritic chest pain (46.9% vs. 17.4%, P<0.001), hemoptysis (29.7% vs. 2.5%, P<0.001), fever (26.6% vs. 8.1%, P<0.001), lower limb edema/pain (37.5% vs. 14.0%, P<0.001), white blood cell (WBC) counts (37.5% vs. 24.5%, P=0.032), C-reactive protein (CRP) (65.6% vs. 41.3%, P<0.001), and pleural effusion (45.3% vs. 18.6%, P<0.001) were associated with an increased risk of PI. Multivariate analysis demonstrated that age [odds ratio (OR) 0.975, 95% confidence interval (CI): 0.951-0.999, P=0.045], pleuritic chest pain (OR 2.878, 95% CI: 1.424-5.814, P=0.003), hemoptysis (OR 10.592, 95% CI: 3.503-32.030, P<0.001), lower limb edema/pain (OR 2.778, 95% CI: 1.342-5.749, P=0.006) and pleural effusion (OR 3.127, 95% CI: 1.531-6.388, P=0.002) were independent factors of PI due to PE. No significant difference was recorded between the two groups in treatment and mortality.ConclusionsYoung patients were found to be a higher risk of PI. Pleural effusion was found to be a factor for PI. PI should be considered when pleuritic chest pain, hemoptysis, or lower limb edema/pain are present with peripheral opacity.

Project description:BackgroundIn numerous high-risk medical and surgical conditions, a greater volume of patients undergoing treatment in a given setting or facility is associated with better survival. For patients with pulmonary embolism, the relation between the number of patients treated in a hospital (volume) and patient outcome is unknown.MethodsWe studied discharge records from 186 acute care hospitals in Pennsylvania for a total of 15 531 patients for whom the primary diagnosis was pulmonary embolism. The study outcomes were all-cause mortality in hospital and within 30 days after presentation for pulmonary embolism and the length of hospital stay. We used logistic models to study the association between hospital volume and 30-day mortality and discrete survival models to study the association between in-hospital mortality and time to hospital discharge.ResultsThe median annual hospital volume for pulmonary embolism was 20 patients (interquartile range 10-42). Overall in-hospital mortality was 6.0%, whereas 30-day mortality was 9.3%. In multivariable analysis, very-high-volume hospitals (> or = 42 cases per year) had a significantly lower odds of in-hospital death (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.51-0.99) and of 30-day death (OR 0.71, 95% CI 0.54-0.92) than very-low-volume hospitals (< 10 cases per year). Although patients in the very-high-volume hospitals had a slightly longer length of stay than those in the very-low-volume hospitals (mean difference 0.7 days), there was no association between volume and length of stay.InterpretationIn hospitals with a high volume of cases, pulmonary embolism was associated with lower short-term mortality. Further research is required to determine the causes of the relation between volume and outcome for patients with pulmonary embolism.

Project description:BACKGROUND:Physicians treating acute pulmonary embolism (PE) are faced with difficult management decisions while specific guidance from recent guidelines may be absent. METHODS:Fourteen clinical dilemmas were identified by physicians and haematologists with specific interests in acute and chronic PE. Current evidence was reviewed and a practical approach suggested. RESULTS:Management dilemmas discussed include: sub-massive PE, PE following recent stroke or surgery, thrombolysis dosing and use in cardiac arrest, surgical or catheter-based therapy, failure to respond to initial thrombolysis, PE in pregnancy, right atrial thrombus, role of caval filter insertion, incidental and sub-segmental PE, differentiating acute from chronic PE, early discharge and novel oral anticoagulants. CONCLUSION:The suggested approaches are based on a review of the available evidence and guidelines and on our clinical experience. Management in an individual patient requires clinical assessment of risks and benefits and also depends on local availability of therapeutic interventions.

Project description:INTRODUCTION:Uterine morcellation in minimally invasive surgery has recently come under scrutiny because of inadvertent dissemination of malignant tissue, including leiomyosarcomas commonly mistaken for fibroids. Identification of preoperative risk factors is crucial to ensure that oncologic care is delivered when suspicion for malignancy is high, while offering minimally invasive hysterectomies to the remaining patients. OBJECTIVES:The aim of this study was to characterize risk factors for uterine leiomyosarcomas by reviewing preoperative, intraoperative, and postoperative data with an emphasis on the presence of concurrent fibroids. METHODS:A retrospective case-control study of women undergoing hysterectomy with pathologic diagnosis of uterine leiomyosarcoma at a tertiary care center between January 2005 and April 2014. RESULTS:Thirty-one women were identified with leiomyosarcoma and matched to 124 controls. Cases with leiomyosarcoma were more likely to have undergone menopause and to present with larger uteri (19- vs 9-week sized), with the most common presenting complaint being a pelvic mass (35.5% vs 8.9%). Controls were ten times more likely to have undergone a tubal ligation (30.6% vs 3.2%). Endometrial sampling detected malignancy preoperatively in only 50% of cases. Leiomyosarcomas were more commonly present when pelvic masses were identified in addition to fibroids on preoperative imaging. Most leiomyosarcoma cases (77.4%) were performed by oncologists via an abdominal approach (83.9%), with only 2 of 31 leiomyosarcomas being morcellated. Comparative analysis of preoperative imaging and postoperative pathology showed that in patients with leiomyosarcoma, fibroids were misdiagnosed 58.1% of the time, and leiomyosarcomas arose directly from fibroids in only 6.5% of cases. CONCLUSIONS:Leiomyosarcoma risk factors include older age/postmenopausal status, enlarged uteri of greater than 10 weeks, and lack of previous tubal ligation. Preoperative testing failed to definitively identify leiomyosarcomas, although the presence of synchronous pelvic masses in fibroid uteri should raise clinical suspicion. Given the difficulty of preoperative identification, future efforts should focus on the development of safer minimally invasive techniques for uterine morcellation.

Project description:IntroductionPulmonary embolism (PE) is a significant global cause of mortality, ranking third after myocardial infarction and stroke. ECG findings may play a valuable role in the prognostication of patients with PE, with various ECG abnormalities proving to be reasonable predictors of haemodynamic decompensation, cardiogenic shock, and even mortality. This study aims to assess the value of electrocardiography in predicting inpatient mortality in patients with acute pulmonary embolism, as diagnosed with computed tomography pulmonary angiogram.MethodThis study was a cross sectional analysis based at Tygerberg Hospital, Cape Town, South Africa. Eligible patients were identified from all CT-PA performed between 1 January 2017 and 31 December 2019 (2 years). The ECGs were independently screened by two blinded emergency physicians for predetermined signs that are associated with right heart strain and higher pulmonary artery pressures, and these findings were analysed to in-hospital mortality.ResultsOf the included 81 patients, 61 (75 %) were female. Of the 41 (51 %) patients with submassive PE and 8 (10 %) with massive PE, 7 (17 %) and 3 (38 %) suffered inpatient mortality (p = 0.023) respectively. Univariate ECG analysis revealed that complete right bundle branch block (OR, 8.6; 95 % CI, 1.1 to 69.9; p = 0.044) and right axis deviation (OR, 5.6; 95 % CI, 1.4 to 22.4; p = 0.015) were significant predictors of inpatient mortality.ConclusionEarly identification of patients with pulmonary embolism at higher risk of clinical deterioration and in-patient mortality remains a challenge. Even though no clinical finding or prediction tool in isolation can reliably predict outcomes in patients with pulmonary embolism, this study demonstrated two ECG findings at presentation that were associated with a higher likelihood of inpatient mortality. This single-centre observational study with a small sample precludes concrete conclusions and a large follow-up multi-centre study is advised.

Project description:PurposeThere is limited literature available regards the frequency and characteristics of COVID-19 + ve status among advanced cancer patients referred to an inpatient supportive care consultation(PC) at a tertiary cancer center. Our study aimed to determine the frequency and characteristics of COVID-19 + ve cancer patients seen by PC.MethodsAdvanced cancer patients seen as a consult by PC between June 15 and September 25, 2020, at MD Anderson Cancer Center were eligible for the study. We evaluated the patient demographics, clinical characteristics including symptoms(ESAS), delirium(MDAS), COVID + status prior to, and after PC referral(converters), and type of PC delivery(in person or virtual care).ResultsSixty-six out of 1380 (4.8%) PC consults were COVID-19 + ve: 42 prior to PC (79%), and 14 (21%) were COVID-19 + ve after the PC (converters). COVID-19 + PC patients had lower depression (P = .035), spiritual distress (P = .003), and were more seen frequently virtually (P < 0.001). There was no significant difference between COVID-19-ve patients and converters. Converters had higher symptom distress (P = 0.007), lower delirium (P = 0.014), and were referred earlier (P = .011) compared to COVID + PC patients diagnosed prior to PC consult. Overall, patients seen virtually compared in-person by PC were younger (P = 0.02) and had lower delirium (P = 0.007).ConclusionThe burden of COVID-19 + status among patients referred to PC was low. COVID-19 + ve patients had more frequent virtual visits, lower depression, and spiritual distress scores. Patient seen virtually were significantly younger and had lower delirium. During a new pandemic, universal virtual care might be emphasized especially at initial encounters after admission and further research is needed on the potential efficacy of this intervention.

Project description:ObjectiveTo describe the clinical and radiographic findings in a large cohort of patients with positive cultures for Nocardia emphasizing the differences between invasive disease and colonization.Patients and methodsWe conducted a single-center, retrospective cohort study of 133 patients with a positive Nocardia isolate between August 1, 1998, and November 30, 2018, and a computed tomography (CT) of the chest within 30 days before or after the bacteria isolation date.ResultsPatients with colonization were older (71 vs 65 years; P=.004), frequently with chronic obstructive pulmonary disease (56.8% vs 16.9%; P<.001) and coronary artery disease (47.7% vs 27%, P=.021), and had Nocardia isolated exclusively from lung specimens (100% vs 83.1%; P=.003). On CT of the chest, they had frequent airway disease (84.1% vs 51.7%; P<.001). Patients with invasive nocardiosis had significantly (P<.05) more diabetes, chronic kidney disease, solid organ transplant, use of corticosteroids, antirejection drugs, and prophylactic sulfa. They had more fever (25.8% vs 2.3%; P<.001), cutaneous lesions (14.6% vs 0%; P=.005), fatigue (18% vs 0%; P=.001), pulmonary nodules (52.8% vs 27.3%; P=.006), and free-flowing pleural fluid (63.6% vs 29.4%; P=.024). The patterns of nodule distribution were different-diffuse for invasive nocardiosis and peribronchiolar for Nocardia colonization.ConclusionThe isolation of Nocardia in sputum from a patient with respiratory symptoms does not equal active infection. Only by combining clinical and chest CT findings, one could better differentiate between invasive nocardiosis and Nocardia colonization.

Project description:BackgroundBreathlessness is the prominent symptom of chronic obstructive pulmonary disease (COPD). Despite optimal therapeutic management including pharmacological and non-pharmacological interventions, many COPD patients exhibit significant breathlessness. Chronic breathlessness is defined as breathlessness that persists despite optimal treatment of the underlying disease. Because of the major disability related to chronic breathlessness, symptomatic treatments including opioids have been recommended by several authors. The prevalence of chronic breathlessness in COPD and its management in routine clinical practice have been poorly investigated. Our aim was to examine prevalence, associated characteristics and management of chronic breathlessness in patients with COPD recruited in a real-life tertiary hospital-based cohort.MethodsA prospective study was conducted among 120 consecutive COPD patients recruited, in stable condition, at Nancy University Hospital, France. In parallel, 88 pulmonologists of the same geographical region were asked to respond to an on-line questionnaire on breathlessness management.ResultsSixty four (53%) patients had severe breathlessness (modified Medical Research Council scale≥3), despite optimal inhaled medications for 94% of them; 40% had undergone pulmonary rehabilitation within the past 2 years. The severity of breathlessness increased with increasing airflow limitation. Breathlessness was associated with increased symptoms of anxiety, depression and with osteoporosis. No relation was found with other symptoms, exacerbation rate, or cardiovascular comorbidities. Among the patients with chronic breathlessness and Hospitalized Anxiety and/or Depression score > 10, only 25% were treated with antidepressant or anxiolytic. Among the pulmonologists 46 (52%) answered to the questionnaire and expressed a high willingness to prescribe opioids forchronic breathlessness, which contrasted with the finding that none of these patients received such treatments against breathlessness.ConclusionTreatment approaches to breathlessness and associated psychological distress are insufficient in COPD. This study highlights underuse of pulmonary rehabilitation and symptomatic treatment for breathlessness.
