The Determinants Of Colorectal Cancer Survival Disparities In Nevada, Lucas N. Wassira
The Determinants Of Colorectal Cancer Survival Disparities In Nevada, Lucas N. Wassira
UNLV Theses, Dissertations, Professional Papers, and Capstones
Different population groups across Nevada and throughout the United States suffer disproportionately from colorectal cancer and its after-effects. Overcoming cancer health disparities is important for lessening the burden of cancer. There has been an overall decline in the incidence of and mortality from colorectal cancer (CRC). This is likely due, in part, to the increasing use of screening procedures such as Fecal Occult Blood Test (FOBT) and/or endoscopy, which can reduce the risk of CRC mortality by fifty percent. Nevertheless, screening procedures are routinely used by only fifty percent of Americans aged fifty years and older. Despite overall mortality decreasing …

OBJECTIVES: The present study investigated factors affecting outcome at relapse after previous surgery and adjuvant chemoradiation (crt) in high-risk esophageal cancer patients. PATIENTS AND METHODS: From 1989 to 1999, we followed high-risk resected esophageal cancer patients who had completed postoperative crt therapy. Patients who relapsed with a disease-free interval of less than 3 months were treated with palliative crt when appropriate. Patients with a disease-free interval of 3 months or more were treated with best supportive care. Post-recurrence survival was estimated using the Kaplan-Meier technique, and statistical comparisons were made using log-rank chi-square tests and Cox regression. RESULTS: Of the …

Chronic obstructive pulmonary disease is a highly prevalent, underdiagnosed, and undertreated chronic lung disease. Early and appropriate treatment may help modify the course of the disease with respect to exacerbation timing and frequency, quality of life, and mortality. Steady progress continues to be made in understanding the disease pathogenesis and treatment modalities, and there is some evidence that outcomes are improving.

Exposure To Indoor Biomass Fuel Pollutants And Asthma Prevalence In Southeastern Kentucky: Results From The Burden Of Lung Disease (Bold) Study, Anna C. Barry, David M. Mannino, Claudia Hopenhayn, Heather Bush
David M. Mannino
BACKGROUND:
Asthma is a chronic inflammatory respiratory disease, characterized by episodic and reversible airflow obstruction and airway hyperresponsiveness and is influenced by both genetic and environmental factors.
METHODS:
The Burden of Obstructive Lung Disease (BOLD) survey was used to determine the prevalence of self-reported asthma in a target population of 325,000 adults aged > or =40 in Southeastern Kentucky. Postbronchodilator spirometry was used to classify subjects based on lung function. Risk factors for asthma in this population, in particular indoor usage of biomass fuels, were evaluated.
RESULTS:
The overall study population was comprised of 508 individuals, with 15.5% reporting current asthma …
Concurrent Sexual Partnerships Do Not Explain The Hiv Epidemics In Africa: A Systematic Review Of The Evidence, Larry Sawers, Eileen Stillwaggon
Concurrent Sexual Partnerships Do Not Explain The Hiv Epidemics In Africa: A Systematic Review Of The Evidence, Larry Sawers, Eileen Stillwaggon
Economics Faculty Publications
The notion that concurrent sexual partnerships are especially common in sub-Saharan Africa and explain the region’s high HIV prevalence is accepted by many as conventional wisdom. In this paper, we evaluate the quantitative and qualitative evidence offered by the principal proponents of the concurrency hypothesis and analyze the mathematical model they use to establish the plausibility of the hypothesis.
We find that research seeking to establish a statistical correlation between concurrency and HIV prevalence either finds no correlation or has important limitations. Furthermore, in order to simulate rapid spread of HIV, mathematical models require unrealistic assumptions about frequency of sexual …

The Role Of Unrealistic Optimism In Explaining Preventive Behaviors In High Versus Low Endemic Malaria Settings In Belize, Daniel G. Handysides
The Role Of Unrealistic Optimism In Explaining Preventive Behaviors In High Versus Low Endemic Malaria Settings In Belize, Daniel G. Handysides
Loma Linda University Electronic Theses, Dissertations & Projects
Background: Of all the diseases an individual can encounter in the world, malaria is one of the most destructive. Simple measures like sleeping under a bednet would greatly reduce the burden (Abeku, 2007). When people estimate their risk relative to others, they are most often unrealistically optimistic, which may explain why those at risk often fail to perform behaviors, such as using a bednet that will reduce their risk. However, one study showed that people at high risk for malaria held pessimistic perceptions of their risk for the disease, but the reasons for this finding are unclear (Morrison, Ager, & …

A infecção é a mais frequente e grave complicação que acomete pacientes que procuram serviços estéticos e/ou funcionais em clínicas de cirurgia plástica. Uma infecção hospitalar eleva os custos do processo, tanto para o paciente quanto para a empresa. Diante disso, torna-se importante a instalação de uma comissão de controle de infecção hospitalar, tendo como responsável um enfermeiro. A importância deste profissional se dá por meio da organização da Central de Material Estarilizado (CME), bem como do estabelecimento de outras medidas efetivas para a prevenção e controle de infecções nas clínicas apresentadas ao longo desse artigo.

OBJECTIVES: Obesity is associated with an increased risk of heart failure (HF). Among patients presenting with acute HF, however, differences in clinical characteristics, treatment regimens, and short-term prognosis of varying weights are largely unknown, particularly from a broader population-based perspective. METHODS: A total of 3722 patients admitted with acute HF to 11 greater Worcester (Massachusetts, USA) hospitals during 1995 and 2000 were categorized as being lean (n = 216), normal weight (n = 1465), overweight (n = 1007), or obese (n = 1034) at the time of hospitalization. RESULTS: Obese patients with decompensated HF were significantly younger (mean age = …

Erroneous Measurement Of Intracranial Pressure Caused By Simultaneous Ventricular Drainage: A Hydrodynamic Model Study, H. Wilkinson, Jorge Yarzebski, E. Wilkinson, Frederick Anderson
Jorge L. Yarzebski
Intracranial pressure (ICP) is often measured from intraventricular catheters, a technique that allows therapeutic drainage of ventricular cerebrospinal fluid (CSF) as an aid in controlling ICP and circumventing obstruction. Drainage of CSF simultaneously with ongoing ICP measurement has been advocated as safe and efficient, and devices are commercially available to permit this practice; however, this concept has been seriously challenged, based on clinical observations. The inaccuracy induced by simultaneous CSF drainage and ICP monitoring is quantitated in this report in a mechanical brain model using a standard ventricular catheter. The following conclusions have been confirmed: 1) rapid CSF drainage induces …

The technique of percutaneous radiofrequency (RF) upper thoracic sympathectomy mandates an exact knowledge of the anatomical location of the sympathetic ganglia. Because conflicting descriptions are given in anatomy texts, we examined the T2 and T3 sympathetic ganglia in 48 sympathetic chains in adult cadavers to measure the exact location of the ganglia. Measurements were made relative to their distances (a) dorsal to the ventral surface of the vertebral body and (b) rostral or caudal to the midpoint of the vertebral body. Median locations of T2 and T3 ganglia were 17 to 20 mm dorsal to the ventral surface of the …

Recent Trends In Exposure To Secondhand Smoke In The United States Population, Chieh-I Chen, Tanya Burton, Christine L. Baker, Vera Mastey, David M. Mannino
David M. Mannino
Background Previous research using the National Health and Nutrition Examination Surveys (NHANES) data documented a significant downward trend in secondhand smoke (SHS) exposure between 1988 and 2002. The objective of this study was to assess whether the downward trend in exposure continued from 2001 through 2006.
Methods We analyzed data from the 2001-2006 NHANES to estimate exposure of nonsmokers to SHS. Geometric means of serum cotinine levels for all nonsmokers were computed.
Results Overall serum cotinine levels (95% Confidence Intervals) in 2001-2002, 2003-2004, and 2005-2006 were 0.06 ng/mL (0.05-0.07), 0.07 ng/mL (0.06-0.09), and 0.05 ng/mL (0.05-0.06), respectively. Subgroup analysis by …

Association Between Obesity, Depression, And Inflammation Among Seventh-Day Adventists In The Biopsychosocial Religion And Health Study, Michael Paalani
Loma Linda University Electronic Theses, Dissertations & Projects
The effects of obesity and depression on morbidity and mortality may be mediated by inflammatory processes. Homeostasis within the immune system depends on a balance of pro-inflammatory and anti-inflammatory cytokine molecules, so chronic inflammatory diseases may result from cytokine dysregulation. The target population consisted of 508 Seventh Day Adventists (SDAs) who participated in the Biopsychosocial Religion and Health Study (BHRS), a sub-study of the Adventist Health Study-2. The study was a cross-sectional analysis of the association between obesity, depression, and inflammation after controlling for demographic, socioeconomic, health behavioral, and health status variables among BHRS participants.
Obesity was assessed by body …

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 …

Oral Cancer In Nevada: A Public Health Perspective, Karl Kingsley
UNLV Theses, Dissertations, Professional Papers, and Capstones
Cancer is the second leading cause of death in the United States, and oral cancer remains the eighth leading cause of cancer death among US males. Although previous epidemiologic studies have found that overall rates of cancer, including oral cancer, have declined in the US in recent decades – these declines are neither uniform nor consistent within this population. Anecdotal evidence has suggested that rates of oral cancer in Nevada are relatively high, although no evidence was available to support these assertions.
Oral Cancer Epidemiology: Based upon this information, a detailed and thorough epidemiologic examination of oral cancer rates in …

Objective:
To describe the item-selection and item-reduction for the Lung Function Questionnaire (LFQ), being developed to help clinicians identify patients appropriate for diagnostic evaluation for chronic obstructive pulmonary disease (COPD) using spirometry.
Methods:
Item selection and reduction were based on information from 387 ≥40-year-old respondents to the third National Health and Nutrition Examination Survey who had self-reported chronic bronchitis. Item reduction involved stepwise logistic regression. The accuracy of the final subset of items for identifying individuals with airflow obstruction (forced expiratory volume in one second/forced vital capacity <0.70) versus those without it was assessed with receiver operating characteristic analysis. Content and face validity were assessed using focus groups of primary care physicians (n = 16) and interviews with COPD patients (n = 16).
Results:
The model with all five items (age; smoking history; the presence of …
