Prenatal Participation In Wic : Impact On Breastfeeding Initiation And Duration And On Infant Weight Gain, Lynn S. Edmunds Jan 2012

Prenatal Participation In Wic : Impact On Breastfeeding Initiation And Duration And On Infant Weight Gain, Lynn S. Edmunds

Legacy Theses & Dissertations (2009 - 2024)

Background: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is one of the most studied federal food assistance programs. However, few studies have examined the association between maternal WIC participation and breastfeeding or weight gain during infancy. Prenatal WIC participation provides an important widow of influence on birth outcomes but also on early life risk factors for chronic disease. This study utilizes a cohort of WIC enrolled infants to assess the added effect of prenatal exposure to WIC on two specific outcomes - breastfeeding initiation and duration and rate of infant weight gain.


Detection And Epidemiological Patterns Of Drug Resistance Mutations In Nys Plasmodium Falciparum Clinical Malaria Specimens, Jennifer L. Conaway Jan 2012

Detection And Epidemiological Patterns Of Drug Resistance Mutations In Nys Plasmodium Falciparum Clinical Malaria Specimens, Jennifer L. Conaway

Legacy Theses & Dissertations (2009 - 2024)

Plasmodium falciparum is a human-infective parasite that causes the most severe form of malaria. Resistance to a wide spectrum of antimalarials has been documented in this species, and single strains may be resistant to several drugs. A new technology, pyrosequencing, has been shown to be useful for the rapid detection of SNPs involved in drug resistance. It can be used in a clinical setting and readily detects new mutants, which frequently appear in this species due to strong selection for antimalarial resistance. In this study, a pyrosequencing protocol was developed to identify mutations in the Plasmodium falciparum genes Pfcrt, Pfdhps, …


Association Between Chemical Constituents Of Particulate Matter And Cardiovascular And Respiratory Morbidities In Nys, Rena Jones Jan 2012

Association Between Chemical Constituents Of Particulate Matter And Cardiovascular And Respiratory Morbidities In Nys, Rena Jones

Legacy Theses & Dissertations (2009 - 2024)

Improved understanding of health risks from short- and long-term exposure to fine particulate matter (PM2.5) constituents may explain seasonal and geographic heterogeneity in PM2.5-health associations and inform control efforts targeting PM sources. Few studies have examined PM species health effects; most have been limited by their exposure assessments and modeling approaches. The goals of this project were to improve the PM exposure assessment and explore relationships between PM2.5 species and health in acute and chronic contexts.


Seafood Consumption And Use Of Asian Herbal Preparation As A Source Of Exposure To Multiple Trace Elements In The Study Of Metals And Assisted Reproductive Technologies (Smart), Dongsul Kim Jan 2012

Seafood Consumption And Use Of Asian Herbal Preparation As A Source Of Exposure To Multiple Trace Elements In The Study Of Metals And Assisted Reproductive Technologies (Smart), Dongsul Kim

Legacy Theses & Dissertations (2009 - 2024)

As, Cd, Cs, Hg, Pb, and Zn may be associated with in vitro fertilization (IVF) outcomes. Seafood and Asian herbal preparations are identified as sources of exposure to these essential and non-essential trace elements in humans. The goal of the study is to assess associations between seafood consumption and the use of Asian herbal preparations and levels of essential and non-essential trace elements in biologic specimens collected from couples undergoing IVF. Fifty-nine couples completing a first IVF cycle at the University of California, San Francisco (UCSF) Center for Reproductive Health were recruited to participate in the Study of Metals and …


Short-Term Associations Between Pm2.5, Black Carbon, Delta-C, And Cardiovascular Diseases In A Large Developing Megacity, Daniel Malashock Jan 2012

Short-Term Associations Between Pm2.5, Black Carbon, Delta-C, And Cardiovascular Diseases In A Large Developing Megacity, Daniel Malashock

Legacy Theses & Dissertations (2009 - 2024)

Introduction: Association between ambient air pollution and cardiovascular disease (CVD) have been demonstrated by many epidemiological studies in developed countries, however few studies have been performed in developing countries of Asia.


Trace Element Analysis Of Environmental And Clinical Materials Using Novel Instrumentation Based On X-Ray Fluorescence Spectrometry : New Capabilities For Public Health Laboratories, Kathryn G. Mcintosh Jan 2012

Trace Element Analysis Of Environmental And Clinical Materials Using Novel Instrumentation Based On X-Ray Fluorescence Spectrometry : New Capabilities For Public Health Laboratories, Kathryn G. Mcintosh

Legacy Theses & Dissertations (2009 - 2024)

X-ray fluorescence (XRF) spectrometry is a well-established analytical technique for determining the elemental content of many different materials. XRF has long been used for public health applications, particularly for identifying lead-based paint hazards. The primary advantage of XRF over other atomic spectrometric techniques is that it is nondestructive. In addition, little sample preparation is required, so results are obtained rapidly and at low cost. The principal aim of this study was to characterize the utility and reliability of current XRF instrumentation for use in the environmental health sciences. Interest in the use of XRF for detecting lead in children's toys …


Evaluation Of The Short- And Long- Term Drinking Water Sustainability Programs For Point Water Sources And Public Water Supplies (Pws) In Developing Countries : Case Study Of Uganda, Shedrack R. Nayebare Jan 2012

Evaluation Of The Short- And Long- Term Drinking Water Sustainability Programs For Point Water Sources And Public Water Supplies (Pws) In Developing Countries : Case Study Of Uganda, Shedrack R. Nayebare

Legacy Theses & Dissertations (2009 - 2024)

Providing quantity and quality potable water in Uganda and other developing countries is still significantly problematic. This project aimed at identifying and prioritizing possible actions on how sustainable and high quality potable water in Uganda's water supply systems could be improved. A review of both the current water supply systems and Ugandan government programs was completed in an effort to describe the existing state of Uganda's water supply. Aspects of quantity, quality, treatment methods, infrastructure, storage and distribution of water for the different water systems were assessed. These characteristics were compared to water supply systems and regulations in the U.S., …


Occupational Exposure And Risk Of Skin Cancer In A Multinational European Study, Simona Surdu Jan 2012

Occupational Exposure And Risk Of Skin Cancer In A Multinational European Study, Simona Surdu

Legacy Theses & Dissertations (2009 - 2024)

Non-melanoma skin cancers (NMSC) comprise more than one third of all cancers, and are increasing worldwide. The most common NMSC are Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC). Studies on humans and animals suggest that sunlight and arsenic play important roles in the pathogenesis of these skin malignancies. However, the number of epidemiological studies focusing on NMSC in workers exposed to ultraviolet (UV) radiation or airborne arsenic is limited, and the findings are contradictory.
