Abstract
A gossypiboma refers to a surgical sponge or gauze accidentally retained inside a patient during a procedure. It is more commonly encountered after abdominal surgeries. When seen in the thorax, it is usually located within the pleural cavity. We report a case of a 42-year old woman who was found to have a gossypiboma mimicking a simple aspergilloma twenty years after a left thoracotomy. The surgical gauze identified on a CT-scan of her chest appears to have migrated into her lung airways.

Abstract
Fatal lactic acidosis has been reported while on the treatment with Nucleoside/nucleotide analogues (NA) for the treatment of hepatitis B, C and HIV. No cases of such a complication have been reported in hematopoietic stem cell transplant (HSCT) recipients. We present a 65-year male who underwent autologous HSCT for the treatment of multiple myeloma. Prior to transplant he was started on single agent tenofovir alafenamide (TAF) for treatment of resolved hepatitis B infection. He presented few weeks later with severe lactic acidosis. Other causes of lactic acidosis were excluded. The patient died of multi-organ failure despite stopping TAF and aggressive supportive care. The case demonstrates the need for increased awareness of this potential complication of NA treatment in the course of transplantation.

Abstract
Notable progress has been made in the past years in the classification, diagnosis and treatment of pulmonary aspergillosis. New criteria were proposed by the Working Group of the International Society for Human and Animal Mycology (ISHAM) for the diagnosis of allergic bronchopulmonary aspergillosis (ABPA). The latest classification of chronic pulmonary aspergillosis (CPA) suggested by the European Society for Clinical Microbiology and Infectious Diseases (ESCMID) has become widely accepted among clinicians. Subacute invasive pulmonary aspergillosis is now considered a type of CPA, yet it is still diagnosed and treated similarly to invasive pulmonary aspergillosis (IPA). Isavuconazole, an extended-spectrum triazole, has recently been approved by the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of IPA. The most recent Infectious Diseases Society of America (IDSA) guidelines strongly recommend reducing mold exposure to patients at high risk for pulmonary aspergillosis. The excessive relapse rate following discontinuation of therapy remains a common reality to all forms of this semi-continuous spectrum of diseases. This highlights the need to continuously reassess patients and individualize therapy accordingly. Thus far, the duration of therapy and the frequency of follow-up have to be well characterized.

Abstract
INTRODUCTION: Totally implantable venous access devices are used extensively worldwide in cancer patients for administration of venotoxic agents, blood sampling, and nutrition. Their tip is usually positioned at the junction of superior vena cava and right atrium. Inferior vena cava filters are usually used for deep venous thrombosis in cases where anticoagulation is contraindicated; they can be inserted either via internal jugular or femoral access depending on patient conditions and preference. CASE DESCRIPTION: We are describing here a case of totally implantable venous access device fracture following a right internal jugular approach for inferior vena cava filter placement as the patient had inferior vena cava thrombus below the renal veins, extending into the right common iliac vein prohibiting femoral approach. CONCLUSION: Iatrogenic fracture of totally implantable venous access device is a potential complication of accessing the internal jugular vein for other procedures such as insertion of inferior vena cava filter.

Abstract
PURPOSE Several studies showed conflicting results about prognosis and predictors of outcome of critically ill patients with hematological malignancies (HM). The aim of this study is to determine the hospital outcome of critically ill patients with HM and the factors predicting the outcome. METHODS AND MATERIALS All patients with HM admitted to MICU at a tertiary academic medical center were enrolled. Clinical data upon admission and during ICU stay were collected. Hospital, ICU, and 6 months outcomes were documented. RESULTS There were 130 HM patients during the study period. Acute Leukemia was the most common malignancy (31.5%) followed by Non-Hodgkin's Lymphoma (28.5%). About 12.5% patients had autologous HSCT and 51.5% had allogeneic HSCT. Sepsis was the most common ICU diagnosis (25.9%). ICU mortality and hospital mortality were 24.8% and 45.3%, respectively. Six months mortality (available on 80% of patients) was 56.7%. Hospital mortality was higher among mechanically ventilated patients (75%). Using multivariate analysis, only mechanical ventilation (OR of 19.0, CI: 3.1-117.4, P: 0.001) and allogeneic HSCT (OR of 10.9, CI: 1.8-66.9, P: 0.01) predicted hospital mortality. CONCLUSION Overall hospital outcome of critically ill patients with HM is improving. However those who require mechanical ventilation or underwent allogeneic HSCT continue to have poor outcome.

Abstract
Acute respiratory failure (ARF) is the principal cause for ICU admission and mortality in cancer patients. Early diagnosis and management of these patients entail unique challenges to the intensivist. This chapter reviews the common causes of ARF in cancer patients along with a global diagnostic and management approach. Oncologists and intensivists as a team must establish clear treatment goals for every cancer patient requiring mechanical ventilation.

Abstract
INTRODUCTION: Survival from lung cancer is improving. There are limited data on the causes of death in 5-year survivors of lung cancer. The aim of this study is to explore the causes of death in long-term survivors of non-small cell lung cancer (NSCLC) and describe the odds of dying from causes other than lung cancer in this patient population. METHODS: An analysis of 5-year survivors of newly diagnosed NSCLC from 1996 to 2007, in Metropolitan Detroit included in Surveillance, Epidemiology, and End Results program, was done. RESULTS: Of 23,059 patients identified, 3789 (16.43%) patients were alive at 5-year period (long-term survivors) and 1897 (50.06%) patients died in the later follow-up period (median 88 months; range 1–219 months). The causes of death besides lung cancer were observed in 55.2% of these patients. The most common causes of death were cardiovascular diseases (CVDs) (16%), chronic obstructive pulmonary diseases (11%), and other malignancies (8%). Patients older than 65 years, males, and those who underwent surgery for treatment of lung cancer faced a greater likelihood of death by other causes as compared to lung cancer (OR: 1.45, 95% confidence interval [CI]: 1.18–1.77; OR: 1.24, 95% CI: 1.02–1.51; and OR: 1.39, 95% CI: 1.06–1.82, respectively) CONCLUSIONS: Five-year survivors of NSCLC more commonly die from causes such as CVDs, lung diseases, and other malignancies. Aggressive preventive and therapeutic measures of these diseases may further improve the outcome in this patient population.

Abstract
Influenza infection and Pneumocystis jirovecii pneumonia (PJP) in hematopoietic stem cell transplant (HSCT) patients are well characterized; however, no dual infections have been reported in this patient population and little evidence of mechanisms of interaction between the two infections exists. We present a 53-year-old male allogeneic HSCT patient on immunosuppressive therapy for the treatment of graft versus host disease initially diagnosed with influenza A H3 and later PJP. Despite the development of acute respiratory distress syndrome, the patient was successfully treated with appropriate antimicrobial therapy and aggressive supportive care. This case demonstrates the necessity of maintaining a high index of suspicion for fungal (including PJP) coinfection or superinfection in the setting of worsening influenza infection.

Abstract
Over the coming years, accelerating progress against cancer will be associated with an increased number of patients who require life-sustaining therapies for infectious or toxic chemotherapy-related events. Major changes include increased number of cancer patients admitted to the ICU with full-code status or for time-limited trials, increased survival and quality of life in ICU survivors, changing prognostic factors, early ICU admission for optimal monitoring, and use of noninvasive diagnostic and therapeutic strategies. In this review, experts in the management of critically ill cancer patients highlight recent changes in the use and the results of intensive care in patients with malignancies. They seek to put forward a standard of care for the management of these patients and highlight important updates that are required to care for them. The research agenda they suggest includes important studies to be conducted in the next few years to increase our understanding of organ dysfunction in this population and to improve our ability to appropriately use life-saving therapies or select new therapeutic approaches that are likely to improve outcomes. This review aims to provide more guidance for the daily management of patients with cancer, in whom outcomes are constantly improving, as is our global ability to fight against what is becoming the leading cause of mortality in industrialized and non-industrialized countries.

Abstract
BACKGROUND We evaluated the outcome of subjects with ARDS in relation to etiology and severity in a retrospective cohort study of the ARDS Network randomized controlled trials. The primary outcome was 28-d mortality. The secondary outcomes were 60-d mortality and ventilator- and ICU-free days. For severity of ARDS, subjects were stratified according to PaO2/FIO2. The etiology of ARDS was classified into sepsis, pneumonia, aspiration, trauma, and others. RESULTS A total of 2,914 subjects were included in these trials. Outcomes were modeled with multivariable regressions adjusted for baseline covariates, age, sex, race, Acute Physiology and Chronic Health Evaluation III (APACHE III), vasopressor use, modified lung injury score, diabetes mellitus, cancer status, body mass index, pre-ICU location, ICU location, and study. There was no statistically significant difference in 28-d mortality in relation to ARDS severity. Subjects with trauma, compared with other etiologies of ARDS, had significantly lower mortality at 28 d (odds ratio [OR] = 0.47, 95% CI 0.26-0.83, P = .01). Sixty-day mortality was significantly lower for trauma subjects and those with severe ARDS group (OR = 0.5, 95% CI 0.3-0.85, P = .01 and OR = 0.71, 95% CI 0.52-0.98, P = .034, respectively). There were statistically significantly more ICU-free days and ventilator-free days for the aspiration group (OR = 1.09, 95% CI 1.02-1.17, P = .01 and OR = 1.09, 95% CI 1.02-1.16, P = .01, respectively). There was no statistically significant difference in ICU-free days or ventilator-free days in relation to severity of ARDS. CONCLUSIONS Severity of ARDS based on PaO2/FIO2 did not impact 28-d mortality, ventilator-free days, or ICU-free days. Among the etiologies of ARDS, trauma subjects had the lowest 28- and 60-d mortality, whereas subjects with aspiration had more ICU-free days and ventilator-free days.

Abstract
Azithromycin has a well-characterized bacteriostatic activity. However, it also has a robust immunomodulatory effect that has proven beneficial in a variety of chronic illnesses. This effect results in decreased production of pro-inflammatory cytokines in the acute phase and promotes resolution of chronic inflammation in the later phases. Specifically, azithromycin has direct activity on airway epithelial cells to maintain their function and reduce mucus secretion. These characteristics have resulted in the use of azithromycin in the management of a variety of chronic lung diseases including chronic obstructive pulmonary disease, cystic fibrosis (CF), non-CF bronchiectasis, bronchiolitis obliterans syndrome, diffuse panbronchiolitis, and asthma. In this review, we present the evidence supporting the role of azithromycin in these conditions with an emphasis on the clinical aspects for the practicing physician.

OBJECTIVE Outcome of acute respiratory distress syndrome (ARDS) in relation to age, gender, race, pre-Intensive Care Unit (ICU) location, and type of ICU. METHODS Retrospective cohort study of patients enrolled in the ARDS network randomized controlled trials. RESULTS A total of 2914 patients were included in these trials. Outcomes were adjusted to baseline covariates including APACHE III score, vasopressor use, cause of lung injury, lung injury score, diabetes, cancer status, body mass index, and study ID. Older patients had significantly higher mortality at both 28- and 60-day (odds ratio [OR] 2.59 [95% confidence interval [CI]: 2.12-3.18] P < 0.001 and 2.79, 95% CI: 2.29-3.39, P < 0.001, respectively); less ICU and ventilator free days (relative risk [RR] 0.92, 95% CI: 0.87-0.96, P < 0.001 and 0.92, 95% CI: 0.88-0.96, P < 0.001, respectively). For preadmission location, the 28- and 60-day mortality were lower if the patient was admitted from the operating room (OR)/recovery room (OR 0.65, 95% CI: 0.44-0.95, P = 0.026; and OR = 0.66, 95% CI: 0.46-0.95, P = 0.025, respectively) or emergency department (OR = 0.78, 95% CI: 0.61-0.99, P = 0.039; and OR = 0.71, 95% CI: 0.56-0.89, P = 0.004, respectively), but no statistical differences in ICU and ventilator free days between different preadmission locations. Races other than white and black had a statistically higher mortality (28- and 60-day mortality: OR = 1.47, 95% CI: 1.09-1.98, P = 0.011; and OR 1.53, 95% CI: 1.15-2.04, P = 0.004, respectively). Between whites and blacks, females and males there were no statistically significant differences in all outcomes. CONCLUSION Older patients and races other than blacks and whites have higher mortality associated with ARDS. Mortality is affected by patients preadmission location. There are no differences in outcome in relation to the type of ICU, gender, or between blacks and whites.

Abstract
CONTEXT There are few multicenter studies that examine the impact of systematic screening for palliative care and specialty consultation in the intensive care unit (ICU). OBJECTIVE To determine the outcomes of receiving palliative care consultation (PCC) for patients who screened positive on palliative care referral criteria. METHODS In a prospective quality assurance intervention with a retrospective analysis, the covariate balancing propensity score method was used to estimate the conditional probability of receiving a PCC and to balance important covariates. For patients with and without PCCs, outcomes studied were as follows: 1) change to "do not resuscitate" (DNR), 2) discharge to hospice, 3) 30-day readmission, 4) hospital length of stay (LOS), 5) total direct hospital costs. RESULTS In 405 patients with positive screens, 161 (40%) who received a PCC were compared to 244 who did not. Patients receiving PCCs had higher rates of DNR-adjusted odds ratio (AOR) = 7.5; 95% CI 5.6-9.9) and hospice referrals-(AOR = 7.6; 95% CI 5.0-11.7). They had slightly lower 30-day readmissions-(AOR = 0.7; 95% CI 0.5-1.0); no overall difference in direct costs or LOS was found between the two groups. When patients receiving PCCs were stratified by time to PCC initiation, early consultation-by Day 4 of admission-was associated with reductions in LOS (1.7 days [95% CI -3.1, -1.2]) and average direct variable costs (-$1815 [95% CI -$3322, -$803]) compared to those who received no PCC. CONCLUSION Receiving a PCC in the ICUs was significantly associated with more frequent DNR code status and hospice referrals, but not 30-day readmissions or hospital utilization. Early PCC was associated with significant LOS and direct cost reductions. Providing PCC early in the ICU should be considered.

Abstract
Background This study aimed to evaluate the impact of preoperative pulmonary rehabilitation in lung cancer patients undergoing pulmonary resection surgery with marginal lung function. Methods Short-term outcomes of 42 patients with forced expiratory volume in 1 s < 1.6 L who underwent lung resection between 01/2006 and 12/2010 were reviewed retrospectively. They were divided into group A (no preoperative pulmonary rehabilitation) and group B (receiving pulmonary rehabilitation). In group B, a second set of pulmonary function tests was obtained. Results There were no significant differences in terms of sex, age, race, pathologic stage, operative procedure, or smoking years. Mean forced expiratory volume in 1 s and diffusing capacity for carbon monoxide in group A was 1.40 ± 0.22 L and 10.28 ± 2.64 g∙dL-1 vs. 1.39 ± 0.13 L and 10.75 ± 2.08 g∙dL-1 in group B. Group B showed significant improvement in forced expiratory volume in 1 s from 1.39 ± 0.13 to 1.55 ± 0.06 L ( p = 0.02). Mean intensive care unit stay was 6 ± 5 days in group A vs. 9 ± 9 days in group B ( p = 0.22). Mean hospital stay was 10 ± 4 days in group A vs. 14 ± 9 days in group B ( p = 0.31). There was no significant difference in morbidity or mortality between groups. Conclusion Preoperative pulmonary rehabilitation can significantly improve forced expiratory volume in 1 s in some marginal patients undergoing lung cancer resection. However, it does not improve length of stay, morbidity, or mortality.

Hematol Oncol Stem Cell Ther 2016; 9:131-136. [PMID: 27614231 DOI: 10.1016/j.hemonc.2016.08.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2016] [Revised: 07/14/2016] [Accepted: 08/13/2016] [Indexed: 10/21/2022] [Imported: 08/30/2023] Open
Abstract
OBJECTIVE/BACKGROUND The use of computed tomography pulmonary angiography (CTPA) in the emergency department (ED) for patients suspected to have pulmonary embolism (PE) has been steadily rising in the last 2decades. However, there are limited studies that specifically address the use of CTPA in the ED for cancer patients suspected to have PE. The objective of this study is to assess the rate of positive PE by CTPA in the ED in cancer patients and the variables that are associated with positive results. METHODS A retrospective review of electronic medical records for 208 consecutive patients with cancer who presented to the ED and received a CTPA for suspected PE over a 12-month period. The review included demographics, type and status of cancer, presenting symptoms, CTPA results, calculation of Wells Score, management based on CT findings, and outcome of patients. RESULTS Among the 208 patients who met the inclusion criteria during our study period (mean age 57±13.37years, 73% women, 59% African American, and 32% Caucasians), 5.7% were diagnosed with PE. One hundred and eighty-two (83.7%) had a Wells Score ⩽4, of which 2.2% were found to have to have PE, 22 (16.3%) patients had a Wells Score >4, of which 36.4% were found to have PE (p<.0001). Sensitivity and specificity of Wells >4 was 66.7% and 92.9%, respectively, with an odds ratio of 27 (95% CI 6.6-113.6). Receiver operator characteristics area under the curve for Wells Score was 0.868. Age, race, sex, malignancy type, stage, status, clinical presentation, D-dimer, and a previous history of venous thromboembolism were not found to have statistically significant predictive values. CONCLUSION The yield of CTPA to rule out PE in patients with cancer presenting in the ED is low. Following a validated decision-making protocol such as Wells Criteria may significantly decrease the number of CTPA used in the ED.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a risk factor for lung cancer. This study evaluates alternative measures of COPD based on spirometry and quantitative image analysis to better define a phenotype that predicts lung cancer risk. METHODS A total of 341 lung cancer cases and 752 volunteer controls, ages 21 to 89 years, participated in a structured interview, standardized CT scan, and spirometry. Logistic regression, adjusted for age, race, gender, pack-years, and inspiratory and expiratory total lung volume, was used to estimate the odds of lung cancer associated with FEV1/FVC, percent voxels less than -950 Hounsfield units on the inspiratory scan (HUI) and percent voxels less than -856 HU on expiratory scan (HUE). RESULTS The odds of lung cancer were increased 1.4- to 3.1-fold among those with COPD compared with those without, regardless of assessment method; however, in multivariable modeling, only percent voxels <-856 HUE as a continuous measure of air trapping [OR = 1.04; 95% confidence interval (CI), 1.03-1.06] and FEV1/FVC < 0.70 (OR = 1.71; 95% CI, 1.21-2.41) were independent predictors of lung cancer risk. Nearly 10% of lung cancer cases were negative on all objective measures of COPD. CONCLUSION Measures of air trapping using quantitative imaging, in addition to FEV1/FVC, can identify individuals at high risk of lung cancer and should be considered as supplementary measures at the time of screening for lung cancer. IMPACT Quantitative measures of air trapping based on imaging provide additional information for the identification of high-risk groups who might benefit the most from lung cancer screening.

Trends in Outcomes, Financial Burden, and Mortality for Acute Exacerbation of Chronic Obstructive Pulmonary Disease (COPD) in the United States from 2002 to 2010. COPD 2016; 14:72-79.

Abstract
Chronic obstructive pulmonary disease (COPD) is the cause of substantial economic and social burden. We evaluated the temporal trends of hospitalizations from acute exacerbation of COPD and determined its outcome and financial impact using the National (Nationwide) Inpatient Sample (NIS) databases (2002-2010). Individuals aged ≥ 18 years were included. Subjects who were hospitalized with primary diagnosis of COPD exacerbation and those who were admitted for other causes but had underlying acute exacerbation of COPD (secondary diagnosis) were captured by International Classification of Diseases-Ninth Revision (ICD-9) codes. The hospital outcomes and length of stay were determined. Multivariate logistic regression was used to identify the independent predictors of inpatient mortality. Overall acute exacerbation of COPD-related hospitalizations accounted for nearly 3.31% of all hospitalizations in the year 2002. This did not change significantly to year 2010 (3.43%, p = 0.608). However, there was an increase in hospitalization with secondary diagnosis of COPD. Elderly white patients accounted for most of the hospitalizations. Medicare was the primary payer source for most of the hospitalizations (73-75%). There was a significant decrease in inpatient mortality from 4.8% in 2002 to 3.9% in 2010 (slope -0.096, p < 0.001). Similarly, there was a significant decrease in average length of stay from 6.4 days in 2002 to 6.0 days in 2010 (slope -0.042, p < 0.001). Despite this, the hospitalization cost was increased substantially from $22,187 in 2002 to $38,455 in 2010. However, financial burden has increased over the years.

Abstract
Both autologous and allogeneic hematopoietic stem cell transplants are important therapeutic options for several benign and malignant disorders. Pulmonary complications, although they have become less frequent, remain a significant cause of morbidity and mortality after hematopoietic stem cell transplant. These complications range from bacterial, fungal, and viral pulmonary infections to noninfectious conditions such as diffuse alveolar hemorrhage and idiopathic pneumonia syndrome. Bronchiolitis obliterans syndrome is the primary chronic pulmonary complication, and treatment of this condition remains challenging. This report highlights the advances in the diagnosis and management of the major pulmonary complications after hematopoietic stem cell transplant. It also underscores the need for prospective and multicenter research to have a better understanding of the mechanisms behind these complications and to obtain more effective diagnostic tool and therapeutic options.

Abstract
Lung cancer continues to be a major public health challenge in the United States despite efforts to decrease the prevalence of smoking; outcomes are especially poor for African-American patients compared to other races/ethnicities. Chronic obstructive pulmonary disease (COPD) co-occurs with lung cancer frequently, but not always, suggesting both shared and distinct risk factors for these two diseases. To identify germline genetic variation that distinguishes between lung cancer in the presence and absence of emphysema, we performed whole-exome sequencing on 46 African-American lung cancer cases (23 with and 23 without emphysema frequency matched on age, sex, histology and pack years). Using conditional logistic regression, we found 6305 variants (of 168 150 varying sites) significantly associated with lung cancer subphenotype (P ≤ 0.05). Next, we validated 10 of these variants in an independent set of 612 lung cancer cases (267 with emphysema and 345 without emphysema) from the same population of inference as the sequenced cases. We found one variant that was significantly associated with lung cancer subphenotype in the validation sample. These findings contribute to teasing apart shared genetic factors from independent genetic factors for lung cancer and COPD.
