Latinas And The Traditional Genetic Counseling Model: A Qualitative Study, Stephanie Thompson

Dissertations and Theses (Open Access)

The traditional genetic counseling model reflects an individualized counseling session that includes the presentation of information about genes, chromosomes, personalized risk assessment, and genetic testing and screening options. Counselors are challenged to balance providing educational information with discussion of implications of this information in an allotted amount of time. The aim of this study was to explore the perceptions of pregnant Latinas on the benefits and limitations of the traditional prenatal genetic counseling model and to determine the specific preferences for receiving prenatal genetic counseling. Data were collected through focus groups and one-on-one, semi-structured interviews of twenty-five Spanish speaking Latinas …

Attitudes To Ward And Utilization Of Non-Invasive Prenatal Testing For Chromosome Aneuploidy Among Ob/Gyns, Jessica Davis

Dissertations and Theses (Open Access)

Prenatal diagnosis is traditionally made via invasive procedures such as amniocentesis and chorionic villus sampling (CVS). However, both procedures carry a risk of complications, including miscarriage. Many groups have spent years searching for a way to diagnose a chromosome aneuploidy without putting the fetus or the mother at risk for complications. Non-invasive prenatal testing (NIPT) for chromosome aneuploidy became commercially available in the fall of 2011, with detection rates similar to those of invasive procedures for the common autosomal aneuploidies (Palomaki et al., 2011; Ashoor et al. 2012; Bianchi et al. 2012). Eventually NIPT may become the diagnostic standard of …

Mismatch Repair Deficient Tumors Lacking Known Sporadic Causes: Are They All Due To Lynch Syndrome?, Katherine M. Dempsey

Dissertations and Theses (Open Access)

BACKGROUND: Mismatch repair deficient (MMRD) colorectal (CRC) or endometrial (EC) cancers in the absence of MLH1 promoter hypermethylation and BRAF mutations are suggestive of Lynch syndrome (LS). Positive germline genetic test results confirm LS. It is unclear if individuals with MMRD tumors but no identified germline mutation or sporadic cause (MMRD+/germline-) have LS.

HYPOTHESIS: Since LS is hereditary, individuals with LS should have a stronger family history of LS-related cancers than individuals with sporadic tumors. We hypothesized that MMRD+/germline- CRC and/or EC patients would have less suggestive family histories than LS CRC and/or EC patients.

METHODS: 253 individuals with an …

Puerperal Fever From Hippocrates To Pasteur, Hunter A. Hammill

Houston History of Medicine Lectures (2006-2012)

The death of a mother in childbirth leaving a newborn deserted is a sort of a desecration. This was a frequent event for early physicians. It was felt to be caused by miasmas or punishment from the gods. DaVinci felt the cause was milk stasis, Hippocrates - lochia, Virchow - weather. Then came Semmelweis, Pasteur and Lister. They started a battle with ignorance, hospital administration, budget and academic politics. Ending with the murder of Semmelweis!

The Role Of Acidic Fibroblast Growth Factor And Fibroblast Growth Factor Receptor 4 In High Grade Serous Carcinoma, Tarrik Zaid

Dissertations and Theses (Open Access)

Background: High grade serous carcinoma whether ovarian, tubal or primary peritoneal, continues to be the most lethal gynecologic malignancy in the USA. Although combination chemotherapy and aggressive surgical resection has improved survival in the past decade the majority of patients still succumb to chemo-resistant disease recurrence. It has recently been reported that amplification of 5q31-5q35.3 is associated with poor prognosis in patients with high grade serous ovarian carcinoma. Although the amplicon contains over 50 genes, it is notable for the presence of several members of the fibroblast growth factor signaling axis. In particular acidic fibroblast growth factor (FGF1) …

Effect Of Anchoring On Perceived Amniocentesis Related Miscarriage Risk Within A Latina Population, Laura E. Panos

Dissertations and Theses (Open Access)

Most recognized pregnancies are completed without difficulty, yet there is always a 3-5% background risk to have a child with a birth defect. Amniocentesis, the most common type of prenatal diagnostic test, is used to detect chromosomal abnormalities, such as Down syndrome. Amniocentesis is associated with a risk of complications that can lead to a miscarriage, which is typically quoted to be between 1 in 300 and 1 in 500. Amniocentesis uptake rates are typically lowest within the Latina community, and although the factors related to this have been studied before, no specific conclusions have been reached.

The general population …

First Trimester Screening And Its Impact On Uptake Of Diagnostic Testing, Deanna Darnes

Dissertations and Theses (Open Access)

Introduction: First Trimester Screening (FTS) combines maternal age with fetal nuchal translucency (NT) and maternal analytes to identify pregnancies at an increased risk for Down syndrome and trisomy 18. Though the accuracy of this screening is high, it cannot replace the conclusive accuracy of prenatal diagnostic testing (PDT). Since FTS has been available, a decrease in the number of women who pursue PDT has been observed. This study sought to determine if there has been a significant change in the amount of PDT performed in our clinics, if the type of FTS result affects the patient’s decision regarding PDT, and …

Enhanced Estrogen-Induced Proliferation In Obese Rat Endometrium, Qian Zhang, Qi Shen, Joseph Celestino, Michael R Milam, Shannon N Westin, Robin A Lacour, Larissa A Meyer, Gregory L Shipley, Peter J A Davies, Lei Deng, Adrienne S Mccampbell, Russell R Broaddus, Karen H Lu

Faculty, Staff and Student Publications

OBJECTIVE: We tested the hypothesis that the proliferative estrogen effect on the endometrium is enhanced in obese vs lean animals.

STUDY DESIGN: Using Zucker fa/fa obese rats and lean control, we examined endometrial cell proliferation and the expression patterns of certain estrogen-regulated proproliferative and antiproliferative genes after short-term treatment with estradiol.

RESULTS: No significant morphologic/histologic difference was seen between the obese rats and the lean rats. Estrogen-induced proproliferative genes cyclin A and c-Myc messenger RNA expression were significantly higher in the endometrium of obese rats compared with those of the lean control. Expression of the antiproliferative gene p27Kip1 was suppressed …

Reminiscences Of A Male Midwife, Herman W. Johnson

Texas Medical History E-Books

Herman Walter Johnson was born in Andover, Vermont, August 2, 1883 and died November 14, 1958. He graduated from the University of Buffalo Medical School, New York in 1905. He was Professor and Chairman of the Department of Obstetrics and Gynecology at Baylor College of Medicine.

In his autobiography Dr. Johnson discussed his life, the progress of obstetrics and gynecology and his tenure at Baylor College of Medicine.
