An evaluation of the Texas "A Woman's Right to Know" booklet: A state mandated patient education document for induced abortion

Many patient educational documents are written at a grade level higher than the level at which most individuals can read. This discrepancy can lead to treatment noncompliance and negative health outcomes. Therefore, it is important that patients receive readable health information. The Texas "A Woman's Right to Know" booklet is a state mandated informational document provided to women seeking abortion services. Given the significance of the abortion procedure, it is imperative that women considering having an abortion receive accurate and readable health materials. However, no published studies were found that evaluated the readability of the "A Woman's Right to Know" booklet. Therefore, the purpose of this study was to assess the readability of the "A Woman's Right to Know" booklet. To assess the readability, the Flesch-Kincaid readability test was used to evaluate the reading grade level of the entire "A Woman's Right to Know" booklet and each of the 7 sections of the booklet. The results showed that the readability of the entire booklet as well as each section of the booklet was written below the 8th grade reading level. Although the booklet was written below the estimated United States reading level (8th grade), the reading level of this booklet may still be too high for people in Texas who read below the 8th grade level. Based on these results, it is recommended that health care professionals involved in the distribution and explanation of the "A Woman's Right to Know" booklet provide their patients with both written and verbal medical information. The patients should be allowed to ask questions about the abortion procedure so that they can make the most informed choice.^

Texas Health & Safety Code, Section 165.002 - Right to Breastfeed in Texas

The language used in Section 165.002 of the Texas Health and Safety Code renders breastfeeding women vulnerable and susceptible to harassment, discrimination, and persecution via the Texas Penal Code, Sec. 30.05 (Criminal Trespassing), Sec. 21.08 (Indecent Exposure), and Sec. 21.22 (Indecency with a Child). ^ The overall goal of this paper is to develop a solution to this problem via a proposed law or legislative action that offers protection and support for breastfeeding women who choose to nurse in public. Data to inform these recommendations were collected through a literature review and structured interviews with several breastfeeding stakeholders. A literature review of state and federal breastfeeding legislation was conducted to compare and contrast differences between existing legislation in the United States. Interviews were conducted with breastfeeding legislation stakeholders, which included state legislators who have been active in breastfeeding legislation, breastfeeding mothers, and representatives from the Central Texas Healthy Mothers Healthy Babies Coalition (Centex HMHB Coalition), Texas Breastfeeding Coalition (TXBF coalition), La Leche League International, and the Texas Business Association. Data from the literature and legislation reviews and interviews were transcribed and examined for common themes using qualitative data techniques. ^ Overall, most of the stakeholders came to a general consensus on three points, (1) breastfeeding women are supported by stakeholders within the community, (2) other legislation or penal codes should not override the right to breastfeed, and (3) the current breastfeeding legislation needs to be improved to adequately support breastfeeding women. The interviews with breastfeeding legislation stakeholders yielded two major recommendations for the improvement of Section 165.002 of the Texas Health and Safety Code: advocacy efforts to change the wording of the legislation and education to inform people about the legislation. ^ The right to breastfeed is an important public health issue in that it provides a host of health benefits for mothers and children, and is more economical and environmentally superior to alternative feeding methods. While breastfeeding in public is not illegal nor ever has been, adequate legislation is important to affirm this right for women so that they can confidently feed their children without embarrassment or harassment.^

A woman's right to know: A policy review of abortion legislation in Texas

Introduction: Despite its legalization, abortion remains a controversial issue, one that has many divided on either side of the political spectrum. While there have been several changes made to abortion policy over the past few decades, one that continues to have many asking questions is the Woman’s Right to Know Act, a piece of state imposed abortion legislation that has implemented strict restrictions and requirements of women seeking abortion, including pre-abortion mandatory counseling and a 24 hour waiting period. This project analyzed four controversial components of the mandatory counseling materials in Texas in an attempt to examine the scientific validity behind this legislation. Methods: In order to understand the scientific validity behind the content of the preabortion mandatory counseling, I conducted a systematic literature review to analyze: the purported link between abortion and breast cancer, the existence of fetal pain, the risk of abortion to future fertility, and the negative psychological effects of abortion. An electronic search in EBSCO and PubMed of review articles published between 1995 and 2010 resulted in fourteen reviews. Results: Results of the systematic review found (1) inconclusive evidence suggesting a link between abortion and breast cancer, (2) that fetal pain likely does not occur until the third trimester of pregnancy, (3) that associations exist between induced abortion and subsequent preterm birth and placenta previa, and (4) that there is mixed evidence relating to the negative psychological effects that exist among women having had an abortion and those who have not had abortion. Conclusion: Based on these conclusions, a recommendation was made to revise the current state mandated counseling materials to reflect more accurate and scientifically-based information about abortion and its potential risks.^

STRATEGIES FOR THE TRANSFER OF APPROPRIATE TECHNOLOGY TO DEVELOPING COUNTRIES: THE IMPLEMENTATION AND DEVELOPMENT OF ENVIRONMENTAL HEALTH PROGRAMS IN TUNISIA

This dissertation focuses on Project HOPE, an American medical aid agency, and its work in Tunisia. More specifically this is a study of the implementation strategies of those HOPE sponsored projects and programs designed to solve the problems of high morbidity and infant mortality rates due to environmentally related diarrheal and enteric diseases. Several environmental health programs and projects developed in cooperation with Tunisian counterparts are described and analyzed. These include (1) a paramedical manpower training program; (2) a national hospital sanitation and infection control program; (3) a community sewage disposal project; (4) a well reconstruction project; and (5) a solid-waste disposal project for a hospital.^ After independence, Tunisia, like many developing countries, encountered several difficulties which hindered progress toward solving basic environmental health problems and prompted a request for aid. This study discusses the need for all who work in development programs to recognize and assess those difficulties or constraints which affect the program planning process, including those latent cultural and political constraints which not only exist within the host country but within the aid agency as well. For example, failure to recognize cultural differences may adversely affect the attitudes of the host staff towards their work and towards the aid agency and its task. These factors, therefore, play a significant role in influencing program development decisions and must be taken into account in order to maximize the probability of successful outcomes.^ In 1969 Project HOPE was asked by the Tunisian government to assist the Ministry of Health in solving its health manpower problems. HOPE responded with several programs, one of which concerned the training of public health nurses, sanitary technicians, and aids at Tunisia's school of public health in Nabeul. The outcome of that program as well as the strategies used in its development are analyzed. Also, certain questions are addressed such as, what should the indicators of success be, and when is the time right to phase out?^ Another HOPE program analyzed involved hospital sanitation and infection control. Certain generic aspects of basic hospital sanitation procedures were documented and presented in the form of a process model which was later used as a "microplan" in setting up similar programs in other Tunisian hospitals. In this study the details of the "microplan" are discussed. The development of a nation-wide program without any further need of external assistance illustrated the success of HOPE's implementation strategies.^ Finally, although it is known that the high incidence of enteric disease in developing countries is due to poor environmental sanitation and poor hygiene practices, efforts by aid agencies to correct these conditions have often resulted in failure. Project HOPE's strategy was to maximize limited resources by using a systems approach to program development and by becoming actively involved in the design and implementation of environmental health projects utilizing "appropriate" technology. Three innovative projects and their implementation strategies (including technical specifications) are described.^ It is advocated that if aid agencies are to make any progress in helping developing countries basic sanitation problems, they must take an interdisciplinary approach to progrm development and play an active role in helping counterparts seek and identify appropriate technologies which are socially and economically acceptable. ^

Genetic analysis of Pitx2 in left -right asymmetry and cardiovascular development

Pitx2, a paired-related homeobox gene that is mutated in human Rieger Syndrome, plays a key role in transferring the early asymmetric signals to individual organs. Pitx2 encodes three isoforms, Pitx2a, Pitx2b and Pitx2c. I found that Pitx2c was the Pitx2 isoform for regulating left-right asymmetry in heart, lung and the predominant isoform in guts. Previous studies suggested that the generation of left-right asymmetry within individual organs is an all or none, random event. Phenotypic analysis of various Pitx2 allelic combinations, that encode graded levels of Pitx2c, reveals an organ-intrinsic mechanism for regulating left-right asymmetric morphogenesis based on differential response to Pitx2c levels. The heart needs low Pitx2c levels, while the lungs and duodenum require higher doses of Pitx2c. In addition, the duodenal rotation is under strict control of Pitx2c activity. Left-right asymmetry development for aortic arch arteries involves complex vascular remodeling. Left-sided expression of Pitx2c in these developing vessels implied its potential function in this process. In order to determine if Pitx2c also can regulate the left-right asymmetry of the aortic arch arteries, a Pitx2c-specific loss of function mutation is generated. Although in wild type mice, the direction of the aortic arch is always oriented toward the left side, the directions of the aortic arches in the mutants were randomized, showing that Pitx2c also determined the left-right asymmetry of these vessels. I have further showed that the cardiac neural crest wasn't involved in this vascular remodeling process. In addition, all mutant embryos had Double Outlet Right Ventricle (DORV), a common congenital heart disease. This study provided insight into the mechanism of Pitx2c-mediated late stages of left-right asymmetry development and identified the roles of Pitx2c in regulation of aortic arch remodeling and heart development. ^

Process to develop a State Model Law to reduce prescription drug trafficking while protecting pain management

This paper will discuss the intersection of pill mills and the under-treatment of pain, while addressing the unintended consequence that cracking down on pill mills actually has on medical professionals' treatment of legitimate pain in clinical settings. Moreover, the impact each issue has on the spectrum of related policy, regulatory issues and legislation will be analyzed while addressing the national impact on medical care. Lastly, this paper will outline a process to develop a State Model Law on this subject. This process will include suggestions for the future and how we can move forward to adequately address public safety needs and how we can attempt to mitigate the unintended impact prescription drug trafficking has had on a patient's right to appropriate pain management. This balance is achievable and this paper will address ways we can find this elusive balancing point through the development of a State Model Law. ^

Cystoscopy and the development of invasive bladder cancer in patients presenting with superficial urinary bladder cancer

The objective of this study was to determine the impact of different follow-up cystoscopy frequencies on time to development of invasive bladder cancer in a cohort of 3,658 eligible patients 65 and older with an initial diagnosis of superficial bladder cancer between 1994 and 1998. Bladder cancer patients in the Surveillance, Epidemiology, and End Results (SEER)-Medicare database were used as the study population. ^ It was hypothesized that superficial bladder cancer patients receiving less frequent cystoscopy follow-up would develop invasive bladder cancer sooner after initial diagnosis and treatment than patients seen more frequently for cystoscopy follow-up. Cox Proportional Hazard Regression revealed that patients seen for cystoscopy every 3 or more months were 83–89% less likely to develop invasive cancer than patients seen every 1 to 2 months. A comparison of the 2 groups (1 to 2 months vs. 3≥ months) revealed that the 1 to 2 month group may have had more aggressive disease, and they are seen more frequently as a result. ^ These findings suggest that there are two groups of superficial bladder cancer patients: those at high risk of developing invasive bladder cancer and those at low risk. Patients who developed invasive bladder cancer sooner after initial diagnosis and treatment were seen more frequently for cystoscopy follow-up. The recommendation is that cystoscopy should be based on disease status at 3 months. Standardized schedules give all patients the same number of cystoscopies regardless of their risk factors. This could lead to unnecessary cystoscopies in low risk patients, and fewer than optimal cystoscopies in high risk patients. ^

11beta-hydroxysteroid dehydrogenases as regulators of pulmonary corticosterone during the granulomatous response to trehalose 6,6'-dimycolate

Protection against Mycobacterium tuberculosis requires development and maintenance of granulomatous lesions, a feature considered to be the pathological hallmark of Tuberculosis (TB) disease. Upon encountering Mtb or mycobacterial antigens, specifically trehalose 6,6'-dimycolate (TDM), a strong local pro-inflammatory response is initiated. Systemic production of anti-inflammatory glucocorticoids (GCs) is also induced. Emergence of these antagonists at the inflammatory foci is counterproductive to development of the granulomatous structure and detrimental to host protection against TB. Therefore, it was hypothesized that local enzymatic regulation of GCs occurs locally at the site of granulomatous inflammation. The experiments described here strongly suggest that 11β-hydroxysteroid dehydrogenases (11βHSDs) shuttle GCs between active and inert forms during the acute granulomatous response, supporting the net reduction of corticosterone. The patterns of GC and 11βHSD regulation were specific to the lung (the site of inflammation) and were not observed in other tissues. Furthermore, 11βHSD2, which decreases corticosterone concentrations, was not expressed in models of dysregulated granulomatous inflammation. These findings suggest that cellular exposure to local active GC concentrations is restricted via 11βHSDs as a mechanism to initiate and maintain granuloma formation. The information derived from the experiments outlined in this dissertation provides a better understanding of the events required for establishment and maintenance of the protective granulomatous response. As a practical consequence, exploiting 11βHSD2 modulation of GCs at the site of Mtb infection may lead to improvement of Tuberculosis treatment strategies.^

ROLE OF SOX9 IN UTERINE GLAND DEVELOPMENT AND DISEASE INITIATION

The female reproductive tract (FRT) develops midway through embryogenesis, and consists of oviducts, uterine horns, cervix and upper part of the vagina. The uterine horns are composed of an epithelial layer, luminal (LE) and glandular epithelium (GE), surrounded by a mesenchymal layer, the stroma and myometrium. Interestingly, in most mammals the GE forms after birth and it only becomes fully differentiated as the female reaches sexual maturity. Uterine glands (UG) are made up of GE and are present in all mammals. They secrete nutrients, cytokines and several other proteins, termed histotroph, that are necessary for embryo implantation and development. Experiments in ewes and mice have revealed that females who lack UGs are infertile mainly due to impaired implantation and early pregnancy loss, suggesting that UGs are essential for fertility. Fortunately for us, UGs develop after birth allowing us to peer into the genetic mechanism of tubulogenesis and branching morphogenesis; two processes that are disrupted in various adenocarcinomas (cancer derived from glands). We created 3D replicas of the epithelium lining the FRT using optical projection tomography and characterized UG development in mice using lineagetracing experiments. Our findings indicate that mouse UGs develop as simple tubular structures and later grow multiple secretory units that stem from the main duct. The main aim of this project was to study the role of SOX9 in the UGs. Preliminary studies revealed that Sox9 is mostly found in the nucleus of the GE. vii This observation led to the hypothesis that Sox9 plays a role in the formation and/or differentiation of the GE. To study the role of Sox9 in UGs differentiation, we conditionally knocked out and overexpressed Sox9 in both the LE and GE using the progesterone receptor (Pgr) promoter. Overexpressing Sox9 in the uterine epithelium, parts of the stroma, and myometrium led to formation of multiple cystic structures inside the endometrium. Histological analysis revealed that these structures appeared morphologically similar to structures present in histological tissue sections obtained from patients with endometrial polyps. We have accounted for the presence of simple and complex hyperplasia with atypia, metaplasia, thick-walled blood vessels, and stromal fibrosis; all “hallmarks” that indicate overexpressing Sox9 leads to development of a polyp-like morphology. Therefore, we can propose the use of Sox9-cOE mice to study development of endometrial cystic lesions and disease progression into hyperplastic lesions.

Development of HIF-1α/HIF-1β heterodimerization inhibitors using a novel bioluminescence reporter assay system for in vitro high throughput screening and in vivo imaging

Tumor growth often outpaces its vascularization, leading to development of a hypoxic tumor microenvironment. In response, an intracellular hypoxia survival pathway is initiated by heterodimerization of hypoxia-inducible factor (HIF)-1α and HIF-1β, which subsequently upregulates the expression of several hypoxia-inducible genes, promotes cell survival and stimulates angiogenesis in the oxygen-deprived environment. Hypoxic tumor regions are often associated with resistance to various classes of radio- or chemotherapeutic agents. Therefore, development of HIF-1α/β heterodimerization inhibitors may provide a novel approach to anti-cancer therapy. To this end, a novel approach for imaging HIF-1α/β heterodimerization in vitro and in vivo was developed in this study. Using this screening platform, we identified a promising lead candidate and further chemically derivatized the lead candidate to assess the structure-activity relationship (SAR). The most effective first generation drug inhibitors were selected and their pharmacodynamics and anti-tumor efficacy in vivo were verified by bioluminescence imaging (BLI) of HIF-1α/β heterodimerization in the xenograft tumor model. Furthermore, the first generation drug inhibitors, M-TMCP and D-TMCP, demonstrated efficacy as monotherapies, resulting in tumor growth inhibition via disruption of HIF-1 signaling-mediated tumor stromal neoangiogenesis.

Targeted Deletion Of Functionally Validated Enhancers Defines Their Role in Mouse Limb Development

Transcriptional enhancers are genomic DNA sequences that contain clustered transcription factor (TF) binding sites. When combinations of TFs bind to enhancer sequences they act together with basal transcriptional machinery to regulate the timing, location and quantity of gene transcription. Elucidating the genetic mechanisms responsible for differential gene expression, including the role of enhancers, during embryological and postnatal development is essential to an understanding of evolutionary processes and disease etiology. Numerous methods are in use to identify and characterize enhancers. Several high-throughput methods generate large datasets of enhancer sequences with putative roles in embryonic development. However, few enhancers have been deleted from the genome to determine their roles in the development of specific structures, such as the limb. Manipulation of enhancers at their endogenous loci, such as the deletion of such elements, leads to a better understanding of the regulatory interactions, rules and complexities that contribute to faithful and variant gene transcription – the molecular genetic substrate of evolution and disease. To understand the endogenous roles of two distinct enhancers known to be active in the mouse embryo limb bud we deleted them from the mouse genome. I hypothesized that deletion of these enhancers would lead to aberrant limb development. The enhancers were selected because of their association with p300, a protein associated with active transcription, and because the human enhancer sequences drive distinct lacZ expression patterns in limb buds of embryonic day (E) 11.5 transgenic mice. To confirm that the orthologous mouse enhancers, mouse 280 and 1442 (M280 and M1442, respectively), regulate expression in the developing limb we generated stable transgenic lines, and examined lacZ expression. In M280-lacZ mice, expression was detected in E11.5 fore- and hindlimbs in a region that corresponds to digits II-IV. M1442-lacZ mice exhibited lacZ expression in posterior and anterior margins of the fore- and hindlimbs that overlapped with digits I and V and several wrist bones. We generated mice lacking the M280 and M1442 enhancers by gene targeting. Intercrosses between M280 -/+ and M1442 -/+, respectively, generated M280 and M1442 null mice, which are born at expected Mendelian ratios and manifest no gross limb malformations. Quantitative real-time PCR of mutant E11.5 limb buds indicated that significant changes in transcriptional output of enhancer-proximal genes accompanied the deletion of both M280 and M1442. In neonatal null mice we observed that all limb bones are present in their expected positions, an observation also confirmed by histology of E18.5 distal limbs. Fine-scale measurement of E18.5 digit bone lengths found no differences between mutant and control embryos. Furthermore, when the developmental progression of cartilaginous elements was analyzed in M280 and M1442 embryos from E13.5-E15.5, transient development defects were not detected. These results demonstrate that M280 and M1442 are not required for mouse limb development. Though M280 is not required for embryonic limb development it is required for the development and/or maintenance of body size – adult M280 mice are significantly smaller than control littermates. These studies highlight the importance of experiments that manipulate enhancers in situ to understand their contribution to development.
