Factors Associated with One-year Mortality in Patients with Acute Pulmonary Embolism

Abstract

Introduction: Pulmonary embolism (PE) is the most common cause of vascular death after myocardial infarction and stroke, being associated with high mortality and morbidity rates. The aim of this study was to assess the factors related to 1-year mortality in patients with acute pulmonary embolism who survived the acute event.

Material and methods: In total, 104 patients who had survived the acute episode of pulmonary embolism and underwent a one-month follow-up after the acute event were included in the study. The patients were divided into two groups: Group 1 – patients who had survived at one year after being diagnosed with acute PE (80.76%, n = 84), and Group 2 – patients who had died after one year (19.23%, n = 20).

Results: There were no differences between the 2 groups in relation to gender (p = 0.3), or cardiovascular risk factors (diabetes: p = 0.5, smoking: p = 0.3, hypertension: p = 1, hypercholesterolemia: p = 0.5, hypertriglyceridemia: p = 0.4). Patients who had deceased were significantly older (73.35 ± 9.37 years vs. 66.36 ± 11.17 years, p = 0.005) and had a higher weight compared to the survivors (85.8 ± 21.09 kg vs. 75.89 ± 22.69 kg, p = 0.03). Left ventricular ejection fraction, measured by cardiac ultrasound, was significantly lower in the deceased group compared to survivors (45.63 ± 8.9% vs. 52.86 ± 6.8%, p = 0.03). Multivariate analysis identified the hemodynamic instability (OR = 3.17, p = 0.007), the presence of left QRS axis deviation (OR = 4.81, p = 0.001), associated pulmonary pathologies (OR = 3.2, p = 0.02) as well as the presence of chronic kidney disease (OR = 5, p = 0.04) as the most powerful predictors of death at 1 year in patients with acute PE surviving the acute event.

Conclusions: Factors associated with a higher mortality rate at 1 year in patients who had survived at 1 month following an acute pulmonary embolism episode included: older age, higher body weight, presence of associated pulmonary pathologies, chronic kidney disease, left axis deviation, low left ventricular ejection fraction, hemodynamic instability requiring inotropic support, cardiogenic shock at presentation or cardiac arrest during the acute phase.

Self-Evidence and A Priori Moral Knowledge

Abstract

According to rationalists about moral knowledge, some moral truths are knowable a priori. Rationalists often defend their position by claiming that some moral propositions are self-evidently true. Copp 2007 has recently challenged this rationalist strategy. Copp argues that even if some moral propositions are self-evident, this is not enough to secure rationalism about moral knowledge, since it turns out that such self-evident propositions are only knowable a posteriori. This paper considers the merits of Copp’s challenge. After clarifying the rationalists’ appeal to self-evidence, I show why this rationalist strategy survives Copp’s challenges to it.

Diversity and Distribution of Naked Amoebae in Water Bodies of Sumy Region (Ukraine)

Abstract

Taxonomy of naked amoebae and specifics of their distribution in water bodies of Sumy Region are presented. Our research identified 12 species of naked amoebae of 11 morphotypes. We established their ecological groups relative to abiotic aquatic factors: euryoxidic, stenooxidic, stenobiotic and those that survive in a wide range of organic matter content. According to the species composition, swamp and riparian species complexes of naked amoebae were identified. It was found that species complexes of amoeba are influenced by such factors as temperature, concentration of dissolved oxygen and organic compounds.

The Influence of Attack Helicopter Modernization on Pilot Decision Process

The Influence of Attack Helicopter Modernization on Pilot Decision Process

The proper maintenance of attack helicopters is the basis of the Army Aviation operational effectiveness.

In order to improve the effectiveness of the air support to the Army, this modernization of attack helicopters should be done. It is essential for increasing performance indicators of the Army Aviation. The project of modernization should consider improvement of attack helicopter survivability by increasing resistance to destruction. This aspect has a crucial impact on a pilot decision process during a flight. That is why the modernization should be considered in technical, economic and flying aspects.

Medieval Liturgical Vestments Depicted in the Iconographic Programs of Southern Transylvanian Churches (14th to 16th centuries)

Abstract

This work sets out to list and describe the liturgical vestments present in panel and mural paintings of churches located in southern Transylvania. The surviving body of such vestments on display in the ”Brukenthal” National Museum of Sibiu and that of the Black Church of Brașov not only confirms their use in religious services, but also the fact that they served as models for Transylvanian ecclesiastical painting. Of Western derivation, this type of vestment reflects a way of thinking and stands testament to social status or to the different hierarchies within the church. It is, at the same time, an indication of the development of this kind of craft, produced by specialized workshops.

Atypical Heart Defect in One of the Twins with Trisomy 21

Abstract

Twin gestations are higher risk pregnancies for fetal mortality especially when associated with genetic disorder and congenital heart defect which significantly increases the complication risk in the co-twin including fetal loss, premature delivery, and organ damage. In this report, we present a case of dichorionic twins in 41 years old woman. A trisomy 21 was diagnosed in one twin associated with uncharacteristic congenital heart defect resulting in single twin demise in mid-gestation. The effect of regular care and proper management was delivery of healthy surviving twin.

The role of innovation in the business activity of hidden leaders of the Polish economy

Summary

Globalization and internationalization of the economy compelled the implementation of innovative solutions in companies. Only those organizations that regularly implement innovations have a chance to achieve significant market positions and survive in a competitive environment. The exemplification of such highly innovative companies are H. Simon’s hidden champions. In this publication, there was an attempt made to assess the activity of Polish innovative hidden champions. The results obtained confirm that this specific group of companies places a strong emphasis on innovation. This is evidenced by even such aspects as the number of new innovations, very high amounts spent on R&D or continuous observation of the market in order to discover new needs.

Report on Green Frog (Euphlyctis hexadactylus) from Vengaivasal Lake (Tamilnadu, India)

Abstract

Through the Visual Encounter Survey only one species of green frog (Euphlyctis hexadactylus) was encountered. As we lack previous data we cannot comment on the decline of the species. Frogs, known for specific habitats, are under threats if such habitats are lost. The physico-chemical parameters estimated along with the anuran survey reported that the quality of the lake is not congenial to support the tadpoles of the frogs. The adults can move away from water and survive on land. The habitat, as well as the surrounding wetland, plays a vital role to support a good quantum of anurans.
