Is a complete blood cell count useful in determining the prognosis of pulmonary embolism

SummaryBackgroundPulmonary embolism (PE) is the third cardiovascular cause of hospital admission, following acute coronary syndrome and stroke. Despite high-tech diagnostic methods and new treatment modalities, PEs continue to have a high mortality rate within the first 3 months. This study was designed to assess the additional prognostic value of a complete blood cell count, renal function markers, C-reactive protein, and simplified pulmonary embolism severity index (sPESI) scoring system in PE 100-day mortality.Materials and methodsThe study retrospectively enrolled 208 consecutive patients who were hospitalized with the diagnosis of an acute PE. The patients’ demographic characteristics and clinical and laboratory parameters were recorded from the hospital electronic database and patient’s case notes. The primary end point of the study was an adverse 100-day outcome, defined as death from any cause.ResultsThe all-cause mortality in the first 100 days was 14.42 %. The mean age was 57.87 ± 18.17 (range: 16–93) years. We included 79 (38 %) male and 129 (62 %) female individuals. Red cell distribution width (RDW) and sPESI were found to be statistically significant predictors of PE mortality by multivariate regression analysis. On multivariate regression analysis, RDW was associated with a 4.08-fold (95 % confidence interval: 1.229–13.335, P = 0.021) increase in PE mortality.ConclusionThe results of this study demonstrated that RDW and sPESI may be a useful guide in predicting 100-day mortality. The elevated RDW may alert physicians to possible poor prognosis.ZusammenfassungGrundlagenDie Pulmonalembolie (PE) ist nach dem akuten Koronarsyndrom und dem Schlaganfall der dritthäufigste kardiovaskuläre Grund für eine Aufnahme ins Spital. Trotz hochtechnisierter Diagnostik und neuen Behandlungsmethoden haben Patienten mit einer PE noch immer eine hohe Mortalität innerhalb der ersten 3 Monate nach dem Ereignis. Die vorliegende Studie hat es sich zum Ziel gemacht, den zusätzlichen prognostischen Wert eines kompletten Blutbilds (kBB), des CRPs, von Markern der Nierenfunktion und von einem vereinfachten PE-Schweregrad Index (sPESI) in Bezug auf die Mortalität innerhalb der ersten 100 Tagen nach einer PE zu erheben.Material und MethodenDie Studie erfasste retrospektiv 208 konsekutive Patienten (79 (38 %) Männer, 129 (62 %) Frauen), die wegen der Diagnose einer akuten PE hospitalisiert worden waren. Die demographischen Charakteristika und Laborparameter wurden aus den elektronisch gespeicherten Spitalsdaten und individuellen Krankengeschichten erhoben. Der primäre Endpunkt der Studie war Tod jeder Ursache innerhalb der ersten 100 Tage.ErgebnisseDie Gesamtmortalität betrug 14,42 % innerhalb der ersten 100 Tage. Das mittlere Alter der Patienten lag bei 57,87 ± 18,17 (range: 16–93) Jahren. Die multivariate Regressionsanalyse ergab, dass die Verteilung der Erythrozytenbreite (RDW) und der erhobenen sPESI statistisch signifikante Prädiktoren der Mortalität nach PE waren. In dieser Analyse war die RDW mit einem 4,08 fachen (95 % CI: 1,229–13,335, P = 0,021) Anstieg der Mortalität nach PE verbunden.SchlussfolgerungenDie Ergebnisse dieser Studie zeigen, dass die RDW und sPESI im Bezug auf die Beurteilung der Prognose nach PE nützlich sein können. Erhöhte RDW könnten den Arzt auf eine möglicherweise schlechtere Prognose hinweisen.

Alterations of the neutrophil-lymphocyte ratio during the period of stable and acute exacerbation of chronic obstructive pulmonary disease patients.

We aimed to investigate the importance of neutrophil–lymphocyte ratio (NLR) in patients with chronic obstructive pulmonary disease (COPD) for identifying the severity of inflammation and recognition of acute exacerbation.

Fibulin-3 as a Diagnostic Biomarker in Patients with Malignant Mesothelioma

BACKGROUND New tumour biomarkers are being intensely investigated for malignant mesothelioma (MM). Fibulin-3 is produced in MM but its role remains uncertain. The aim of this study was to evaluate the validity of measuring serum fibulin-3 in the diagnosis and prognosis of MM. MATERIALS AND METHODS This prospective study was performed on 43 patients and 40 healthy controls who were admitted to our hospital between January 2012 and January 2014. Data from MM patients, including demographic and clinical features, routine laboratory data, levels of serum fibulin-3, and treatment outcomes were defined as potential prognostic factors. The receiver operating characteristic (ROC) curve for fibulin-3 was used to detect the cut-off value with highest sensitivity and specificity. Univariate survival analysis was performed using the Kaplan-Meier method in patients with MM. Afterwards, the possible factors identified with univariate analyses were entered into the cox regression analysis. RESULTS Our results revealed that patients with MM had significantly higher serum levels of fibulin-3 than controls. The results showed that the best cut-off point was 36.6 ng/ml with an AUC (area under the curve)=0.976, sensitivity=93.0% and specificity=90.0. In our study, the initial significant poor prognostic factors were advanced stage, high white blood cell count, high platelet count, high C-reactive protein (p<0.05 for each variable). Later, according to multivariate analysis the results showed only advanced stage as significant parameter (p=0.040). CONCLUSIONS We determined that real use for serum fibulin-3 was not for prognosis but for diagnosis in MM. Also advanced stage was associated with poor MM prognosis.

Alterations in platelet count and mean platelet volume as predictors of patient outcome in the respiratory intensive care unit

Thrombocytopenia is associated with increased mortality in intensive care unit (ICU) patients. Mean platelet volume (MPV) reflects platelet function and activation. Elevated MPV is associated with poor outcomes and increased mortality rate in diseases that are commonly encountered in the respiratory ICU.

High social anxiety and poor quality of life in patients with pulmonary tuberculosis.

AbstractPulmonary tuberculosis (PT) has been previously related with various psychosocial adverse consequences including stigmatization and social isolation.Social anxiety is a psychiatric condition that may be associated with social isolation and fear of social exclusion.To date no study has investigated social anxiety and its impact on quality of life (QoL) among patients with PT. Therefore, we aimed to determine the severity of social anxiety in a group of patients with PT.Among patients who were recently discharged from hospital with the diagnosis of PT 94 patients and 99 healthy control subjects who had similar demographical features have been included in the study. A psychiatrist interviewed all participants and a semistructured interview form, which was prepared by the authors, Liebowitz Social Anxiety Scale (LSAS), and Short Form-36 were administered to them.Patients with PT showed higher levels of performance avoidance and social avoidance than healthy control subjects. They reported lower QoL scores across all dimensions. Among patients women showed higher levels of LSAS subscale scores and total score. Fear of social exclusion was predicted by perceived illness severity and emotional role difficulty. On the other hand, perceived illness severity was predicted by fear of exclusion and sedimentation level.PT patients seem to experience higher levels of social anxiety and associated fear of social exclusion that add to their worse QoL during the earlier months of their disease. Among them fear of social exclusion is related with perceived illness severity.

Oxidative Status and Acute Phase Reactants in Patients with Environmental Asbestos Exposure and Mesothelioma

Background and Objectives. The aim of this study was to investigate inflammatory indicators and oxidative status in patients with asbestos exposure with and without mesothelioma and to compare results with data from healthy subjects. Methods. Eighty people with exposure to environmental asbestos and without any disease, 46 mesothelioma patients, and a control group of 50 people without exposure to environmental asbestos were enrolled in this prospective study. Serum total oxidant level (TOL), total antioxidant capacity (TAC), and oxidative stress index (OSI), CRP, transferrin, ceruloplasmin, α-1 antitrypsin, ferritin, and copper levels were measured. Results. Mesothelioma group exhibited higher TOL, OSI, α1-antitrypsin, ferritin and copper levels as compared to the other groups (P < 0.001, P = 0.007, P < 0.0001, P < 0.001, and P < 0.001, resp.). Transferrin was lower in the mesothelioma group than in the other two groups (P < 0.001). The asbestos group had higher TOL, TAC, α1-antitrypsin, and transferrin levels (P < 0.001, P < 0.001, P < 0.001, and P < 0.001, resp.), as well as lower OSI and ferritin levels as compared to the control group (P < 0.001 and P < 0.001). Conclusions. We believe that elevated acute phase reactants and oxidative stress markers (TOL and OSI) in the mesothelioma group can be used as predictive markers for the development of asbestos-related malignancy.

Histopathological and Biochemical Effects of Ecballium elaterium on Sepsis-Induced Lung Injury

ABSTRACT Purpose: The aim of this study was to investigate the role of Ecballium elaterium (EE) on sepsis-induced lung injury. Materials and Methods: A total of 30 male rats were divided into three groups as follows: control, sepsis, and treatment groups (sepsis + EE) with each group containing 10 rats. A rat model of sepsis induced by cecal ligation and puncture (CLP) was used. In the treatment group, rats were injected intraperitoneally with 2.5 mg/kg EE after CLP. Interleukin-6 (IL-6), tumor necrosis factor (TNF)-α, total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values after a 24-hr period were measured via cardiac puncture. Animals were harvested after the procedure and biochemical analysis was done and histopathological changes of the tissue sections of lungs were examined thereafter. Results: A statistically significant decrease was observed in the IL-6 (p < .05), TNF-α (p < .05), and TOS (p < .01) levels in the sera of the treatment group compared to those of the sepsis group. Following the treatment, the TOS (p = .01) and OSI (p < .05) levels in the lung tissue of rats indicated a statistically significant decrease compared to those of the sepsis group. The histopathological follow-up undertaken after the administration of the EE treatment to septic rats showed significantly lower values of alveolar wall thickness (p < .001), interstitial edema (p = .018), and neutrophil infiltration (p = .047). Conclusion: EE treatment may have beneficial effects on sepsis-induced lung injury, and therefore has potential for clinical use.

The impact of anti-smoking laws on high school students in Ankara, Turkey

ABSTRACT OBJECTIVE: To determine the factors affecting the smoking habits of high school students, their thoughts about changes resulting from anti-smoking laws, and how they are affected by those laws. METHODS: In this cross-sectional study, 11th-grade students at eight high schools in Ankara, Turkey, were invited to complete a questionnaire. RESULTS: A total of 1,199 students completed the questionnaire satisfactorily. The mean age of the respondents was 17.0 ± 0.6 years; 56.1% were female, of whom 15.3% were smokers; and 43.9% were male, of whom 43.7% were smokers (p < 0.001). The independent risk factors for smoking were male gender, attending a vocational school, having a sibling who smokes, having a friend who smokes, and poor academic performance. Of the respondents, 74.7% were aware of the content of anti-smoking laws; 81.8% approved of the restrictions and fines; and 8.1% had quit smoking because of those laws. According to the respondents, the interventions that were most effective were the (television) broadcast of films about the hazards of smoking and the ban on cigarette sales to minors. The prevalence of smoking was highest (31.5%) among students attending vocational high schools but lowest (7.5%) among those attending medical vocational high schools. Although 57.1% of the smokers were aware of the existence of a smoking cessation helpline, only 3.7% had called, none of whom had made any attempt to quit smoking. CONCLUSIONS: Although most of the students evaluated were aware of the harmful effects of smoking and approved of the anti-smoking laws, only a minority of those who smoked sought professional help to quit.

The Protective Effects of Caffeic Acid Phenethyl Ester on Acetylsalicylic Acid-induced Lung Injury in Rats

ABSTRACT Aim: We aimed to investigate the protective effect of caffeic acid phenethyl ester (CAPE) on acetylsalicylic acid (ASA)-induced lung damage in rats in the present study. Methods: A total of 40 rats were randomly divided into five groups, with eight rats in each group—group 1: control, not receiving any medication; group 2: ASA (50 mg/kg/day); group 3: ASA (50 mg/kg/day) plus CAPE (20 μg/kg/day); group 4: ASA (100 mg/kg/day); and group 5: ASA (100 mg/kg/day) plus CAPE (20 μg/kg/day). ASA and CAPE were given via orogastric gavage for 5 days. The total oxidant status (TOS), total antioxidant capacity (TAC), oxidant stress index (OSI), and paraoxonase-1 (PON-1) activity of the blood samples and lung tissues were determined. Histopathological examinations of the lung tissues were performed by using light microscopic methods. Results: CAPE treatment significantly increased antioxidant PON-1 level both in the lung tissue and plasma (p < .05). Plasma antioxidant marker (TAC, PON-1) levels significantly increased and oxidant marker (TOS, OSI) levels significantly decreased in CAPE-treated rats (groups 3,5) compared to ASA given no-CAPE groups (group 2,4) (p < .05). Treatment with CAPE improved pulmonary interstitial inflammation and eosinophil accumulation due to ASA histopathologically. Conclusion: Eosinophil-rich inflammation and oxidative stress play important roles in ASA-induced lung toxicity, and CAPE may protect against ASA-induced lung toxicity by reduction of oxidative damage and inflammation in rats.

Two cases of extrapulmonary onset granulomatosis with polyangiitis which caused diffuse alveolar haemorrhage

Granulomatosis with polyangiitis (GPA) is a rare form of vasculitis. Multidisciplinary therapeutic approach and early diagnosis assume vital importance in management of patients with diffuse alveolar haemorrhage caused by GPA, which is a rare complication. The purpose of this study was to present the diagnostic and therapeutic challenges experienced by clinicians in management of two severe cases of GPA with insidious extrapulmonary manifestations which rapidly progressed into acute kidney injury, alveolar haemorrhage and acute respiratory failure.
