Comparing Outcomes For Community-Acquired Pneumonia Between Females And Males: Results From The University Of Louisville Pneumonia Study, Pavani Nathala, Simrat Sarai, Vidyulata Salunkhe, Mahder A. Tella, Stephen P. Furmanek, Forest W. Arnold

The University of Louisville Journal of Respiratory Infections

Introduction: Male sex is currently considered to be a risk factor for worsened community-acquired pneumonia (CAP) outcomes compared to female sex; hence, female sex equates to a lower score on the Pneumonia Severity Index. There is no recent update on sex-based outcomes of patients with CAP. The objective of this study was to compare the outcomes of CAP between females and males.

Methods: This was a secondary analysis of the University of Louisville Pneumonia Study database. It was a prospective population-based cohort study of all hospitalized adults with CAP who were residents of Jefferson County in the city of Louisville, …

Heat Waves And Heat-Related Mortality In East Tennessee, Taiwo Adesoba Aug 2019

Heat Waves And Heat-Related Mortality In East Tennessee, Taiwo Adesoba

Electronic Theses and Dissertations

Heat waves represent a public health challenge that requires multiple responses and warnings to protect vulnerable populations. Although studies have reported an increasing trend of heat wave occurrence in many areas of the world, no clear trend exists in East Tennessee. Using data from Parameter-elevated Relationships on Independent Slope Models (PRISM), CDC WONDER and the United States Census Bureau, the relationship between mortality rates and year was estimated during heat wave events between 1999 and 2010. Five heat wave definitions were tested. Overall, 2007 and 2010 stand out as the years with the highest number of heat wave days in …


Assessment Of Pneumonia Severity Indices As Mortality Predictors, Connor L. English, Thomas Chandler, Brian E. Guinn, Stephen P. Furmanek, Julio A. Ramirez Mar 2019

Assessment Of Pneumonia Severity Indices As Mortality Predictors, Connor L. English, Thomas Chandler, Brian E. Guinn, Stephen P. Furmanek, Julio A. Ramirez

The University of Louisville Journal of Respiratory Infections

BACKGROUND

The leading cause of infectious disease death in the United States is community-acquired pneumonia (CAP). Several pneumonia severity indices exist and are widely used as tools to assist physicians regarding site of care based on risk of death. However, limited data exists that discerns which of the most commonly used severity scores is the best predictor of mortality across multiple time points. The objective of this study is to determine the best mortality predictor at different time points between four of the most commonly used pneumonia severity scores.

METHODS

This was a secondary analysis of a prospective, multicenter, population-based, …


Severity Of Disease And Mortality For Hospitalized Patients With Community-Acquired Viral Pneumonia Compared To Patients With Community-Acquired Bacterial Pneumonia, Richard Y. Kim, Thomas Chandler, Stephen P. Furmanek, Timothy Lee Wiemken, Rodrigo Cavallazzi Feb 2019

Severity Of Disease And Mortality For Hospitalized Patients With Community-Acquired Viral Pneumonia Compared To Patients With Community-Acquired Bacterial Pneumonia, Richard Y. Kim, Thomas Chandler, Stephen P. Furmanek, Timothy Lee Wiemken, Rodrigo Cavallazzi

The University of Louisville Journal of Respiratory Infections

Background: There exists a large body of literature to help identify, diagnose, treat, and manage community-acquired pneumonia (CAP). Despite this, there is little data that directly compares the clinical syndromes and complications of pure bacterial pneumonia to pure viral pneumonia. Our study compares the clinical presentation, morbidity and mortality of viral vs. bacterial etiologies of CAP.

Methods: This was a secondary data analysis of the Community-Acquired Pneumonia Organization (CAPO) international study database. Data was collected concerning patient demographics, physical examination findings, laboratory findings, radiological findings, severity of illness, and clinical outcomes and stratified according to the two study groups, CAVP …


One-Year Mortality In Patients With Community-Acquired Pneumonia, Paula Peyrani, Julio A. Ramirez Oct 2017

One-Year Mortality In Patients With Community-Acquired Pneumonia, Paula Peyrani, Julio A. Ramirez

The University of Louisville Journal of Respiratory Infections

Pneumonia remains a common cause of morbidity and mortality in the US. Although, communityacquired pneumonia (CAP) has traditionally been considered an acute process, more recently, data have emerged showing that patients surviving an episode of CAP are at increased risk of death long after hospital discharged. In this descriptive review, we examine the current knowledge of long-term mortality and propose a hypothesis explaining the pathogenesis of long-term mortality in patients with CAP.


The Role Of Socioeconomic Context In The Association Between Educational Attainment And Morbidity And Mortality, Jennifer Brite Jun 2017

The Role Of Socioeconomic Context In The Association Between Educational Attainment And Morbidity And Mortality, Jennifer Brite

Dissertations and Theses

Although the association between educational attainment and health is one of the most studied in the social science, little is known about the role of social and economic context. Fundamental Cause Theory suggests that the education-health gradient will be weakest in contexts where the better educated are unable to leverage their resources to achieve better health. This dissertation tests several different factors that may moderate the association between educational attainment and morbidity and mortality: 1. Demographic characteristics, including race, immigration status, and gender, 2. Status consistency (defined as education equivalent to that required for current occupation), 3. Unemployment rates at …

The University of Louisville Journal of Respiratory Infections

Background: Reports from the 2009 H1N1 influenza A virus (2009 H1N1) pandemic indicate increased mortality in obese patients hospitalized with pneumonia. However, articles published prior to the pandemic have suggested that obesity may be a protective factor for mortality in these patients. The objective of this study was to compare the impact of obesity on mortality in hospitalized patients with pneumonia due to the 2009 H1N1 versus pneumonia due to other etiologies.

Methods: This was a secondary analysis of the CAPO international cohort study. Study groups were defined as follows: Group One, pneumonia due to 2009 H1N1: Patients hospitalized with …


Roles Of Serum Lycopene In The Prevalence And Mortality Of Metabolic Syndrome In The Adult Population, Guang-Ming Han Aug 2015

Roles Of Serum Lycopene In The Prevalence And Mortality Of Metabolic Syndrome In The Adult Population, Guang-Ming Han

Theses & Dissertations

Metabolic syndrome (MetS) is a cluster of metabolic disorders, including increased fasting glucose, blood pressure, plasma triglyceride, reduced high-density lipoprotein cholesterol and abdominal obesity. It leads to an increased risk of cardiovascular disease and diabetes. The growing prevalence of MetS is strongly related to the increasing prevalence of overweight/obesity. As an antioxidant, lycopene can reduce the risk of MetS. However, it is unclear whether lycopene has similar effects among overweight/obese individuals and whether lycopene can reduce the risk of mortality among individuals with MetS. The purpose of this study was to explore the roles of lycopene in the prevalence and …

Short- And Long-Term Associations Between Widowhood And Mortality In The United States: Longitudinal Analyses, J. Robin Moon, M. Maria Glamour, Anusha M. Vable, Sze Yan Liu, S.V. Subramanian

Department of Public Health Scholarship and Creative Works

Background

Past research shows that spousal death results in elevated mortality risk for the surviving spouse. However, most prior studies have inadequately controlled for socioeconomic status (SES), and it is unclear whether this ‘widowhood effect’ persists over time.

Methods

Health and Retirement Study participants aged 50+ years and married in 1998 (n = 12 316) were followed through 2008 for widowhood status and mortality (2912 deaths). Discrete-time survival analysis was used to compare mortality for the widowed versus the married.

Results

Odds of mortality during the first 3 months post-widowhood were significantly higher than in the continuously married (odds ratio …


A Reappraisal Of Stroke Mortality Trends In Brazil (1979 To 2009), Paulo A. Lotufo Sep 2011

A Reappraisal Of Stroke Mortality Trends In Brazil (1979 To 2009), Paulo A. Lotufo

Paulo A Lotufo

Background: Brazil has the highest cerebrovascular death rate in the Western Hemisphere. We investigated temporal trends according to gender and stroke subtypes. Methods: We analysed mortality rates between 1979 and 2009 for different stroke subtypes. Data were stratified by sex and age (35–74 y). The annual percent change (APC) and significant changes in the trends were identified with joinpoint Poisson regression. The average annual percent change (AAPC) for 2005-09 was presented because that period had the best quality of information. Results: After excluding deaths due to stroke sequels, for men, the APCs (95% confidence intervals) were: 1979-84: 0.7 (-0.8 to …

Cardiovascular And Cancer Mortality In Brazil, Paulo A. Lotufo May 2010

Cardiovascular And Cancer Mortality In Brazil, Paulo A. Lotufo

Paulo A Lotufo

Cancer are not surpassing Cardiovascular Diseases. Here you have an evaluation of mortality in Brazil. The debate was ignited by paper from IARC (International Agency for Research on Cancer) that forecasts cancer deaths surpassing heart diseases rates during de 2020’s. There is no dispute about the fact that - at least in the US and other countries - the decline of mortality deaths for heart diseases presenting a faster pace compared to cancer death rates. It is an epidemiological evidence that must be analyzed and some headline fueling hype as “heart diseases as an old agenda of public health and …

Income Inequality And Homicide Rates In Sao Paulo, Brazil., Paulo A. Lotufo, Isabela M. Bensenor Dec 2009

Income Inequality And Homicide Rates In Sao Paulo, Brazil., Paulo A. Lotufo, Isabela M. Bensenor

Paulo A Lotufo

Description of the epidemic of homicide among poor people in Brazil. In Sao Paulo, Brazil, homicides to men aged 15-44 years increased with an annual percentage change (APC) of 4.7% from 1996 to 2001, and then decreased from 2001 to 2007 with an APC of -14.6%. Analyzing the intra-urban distribution according to family income, the increase in the homicide rate was restricted to men living in the poorest neighbourhoods. In contrast, the decline in homicide rates was observed to men living in all districts. The reasons for this 'up and down' trend are not clear.


Race, Gender And Stroke Subtypes Mortality In Sao Paulo, Brazil., Paulo A. Lotufo Jan 2007

Race, Gender And Stroke Subtypes Mortality In Sao Paulo, Brazil., Paulo A. Lotufo

Paulo A Lotufo

Stroke mortality rates have a discrepant distribution according to socioeconomic variables as social exclusion in Brazil. Recently, data from race has been available from the official health statistics considering five categories: White, Mixed, Black, Asian and Native. We addressed in the city of São Paulo, Brazil, an analysis of cerebrovascular mortality according to race (excluding Asian and Native due to small number of events) and gender during 1999-2001 for people aged 30 to 79 years-old. For all cerebrovascular diseases, age-adjusted mortality rates (x 100,000) for men were higher for Black (150.2), intermediate for Mixed (124.2) and lower for White (104.5) …

Paulo A Lotufo

The decline of stroke mortality rates has been described in Brazil; however, there is no data about stroke subtypes. We described the changes of stroke mortality rates in the city of Sao Paulo (1996-2003) emphasizing intracerebral hemorrhage and cerebral infarction. We categorized mortality data by gender and 10-year age-strata from 30 to 79 years-old. For men, an annual reduction of all types of stroke (-3.9%), and of stroke subtypes as intracerebral hemorrhage (-3.0%) and cerebral infarction was observ e d (-2.7%) as well as, a decline of ill-defined stroke (-7.4%). For women, a decline was observed for all types of …

Stroke Mortality In Sao Paulo (1997-2003). A Description Using The Tenth Revision Of The International Classification Of Diseases, Paulo A. Lotufo

Paulo A Lotufo

Stroke mortality rates are higher in Brazil when compared to other countries. The city of Sao Paulo has a good system of mortality surveillance that allow us to describe the epidemiology of the stroke in the city. Our aim was to describe the stroke mortality pattern by gender and age characterizing the ischemic/hemorrhagic ratio. We categorized mortality data by gender and a 10-year age-strata from 30-39 years-old to 70-79 years-old. To avoid random variations, we calculated the mean of all deaths occurred during the period of 1997 to 2003. Mortality rates were calculated using the population from the Brazilian National …
