Changes to Timeliness and Completeness of Infectious Disease Reporting in Texas After Implementation of an Epidemiologic Capacity Program.

Objectives: The objective of this study was to characterize the changes in timeliness and completeness of disease case reporting in Texas in response to an increasing number of foodborne illnesses and high-consequence infectious disease investigations and the Texas Department of State Health Services' new state-funded epidemiologist (SFE) program.

Methods: We extracted electronic disease case reporting data on 42 conditions from 2012 through 2016 in all local health department (LHD) jurisdictions. We analyzed data on median time for processing reports and percentage of complete reports across time and between SFE and non-SFE jurisdictions using Mann-Whitney tests and scores.

How Do Infectious Disease Epidemiologist Positions Increase Public Health Capacity? Results from a Qualitative Study of Local Health Departments.

The purpose of this study was to characterize changes in and impacts on epidemiologic capacity in local health departments after the implementation of a state-funded epidemiologist program using qualitative data. The study used key informant interviews in Texas health departments, which were conducted and inductively analyzed to identify themes. Five predominant themes emerged from interviews on the impact of state-funded epidemiologists on the epidemiology capacity of local health departments.

Neural tube defects on the Texas-Mexico border: what we've learned in the 20 years since the Brownsville cluster.

We reviewed the published findings from the Texas Neural Tube Defect Project, a 6-year case-control study (1995-2000) of neural tube defects (NTDs) on the Texas-Mexico border. In this review, we highlight what was learned about environmental, genetic, and nutritional factors (i.e.

Dieting to lose weight and occurrence of neural tube defects in offspring of Mexican-American women.

Lowered maternal weight gain and reduction in early pregnancy have been associated with risk of neural tube defects (NTDs) in offspring. We examined the association of self-reported maternal dieting behaviors on the occurrence of NTDs. We conducted a population based case-control study among Mexican-American women who were residents of the 14 Texas counties bordering Mexico.

Maternal smoking, passive tobacco smoke, and neural tube defects.

Background: Although cigarette smoke is a well-established toxin and harmful to the developing embryo, the evidence for an independent effect on the occurrence of neural tube defects (NTDs) is mixed. In this study, we examined the relation between NTDs and maternal exposures to cigarette smoke, including passive smoke exposure.

Methods: We used cases and controls from the large, multistate, population-based National Birth Defects Prevention Study.

Maternal pesticide exposure and neural tube defects in Mexican Americans.

Purpose: The relation between maternal pesticide exposures and neural tube defects (NTDs) in offspring was evaluated in 184 Mexican American case-women and 225 comparison women.

Methods: In-person interviews solicited information about environmental and occupational exposures to pesticides during the periconceptional period.

Results: With adjustment for maternal education, smoking, and folate intake, women who reported using pesticides in their homes or yards were two times more likely (95% confidence interval [CI], 1.

Detection of Staphylococcus aureus including MRSA on environmental surfaces in a jail setting.

We examined jail environmental surfaces to explore whether they might serve as reservoirs of viable methicillin-resistant Staphylococcus aureus (MRSA). We swabbed 132 surfaces, inoculated primary and secondary mannitol salts and oxacillin-resistant screening agar, and used API tests to identify S. aureus and E-tests to determine methicillin/oxacillin resistance.

Maternal serum homocysteine and risk for neural tube defects in a Texas-Mexico border population.

Background: To better understand the neural tube defect (NTD) causal pathway, the authors measured homocysteine, an indicator of tissue micronutrient deficiencies. The authors examined independent and joint associations of serum homocysteine, B12, and folate and red blood cell (RBC) folate with NTD-affected pregnancies.

Methods: Case women in this population-based study had NTD-affected pregnancies and resided and delivered in one of the 14 Texas-Mexico border counties from 1995 through 2000.

Maternal exposures to cigarette smoke, alcohol, and street drugs and neural tube defect occurrence in offspring.

Objectives: Cigarettes, alcoholic beverages, and street drugs contain substances potentially toxic to the developing embryo. We investigated whether maternal cigarette smoking, secondhand smoke exposure, and alcohol or street drug use contributed to neural tube defect (NTD) occurrence in offspring.

Methods: We conducted a population-based case-control study among Mexican American women who were residents of the 14 Texas counties bordering Mexico.

Neural tube defects, micronutrient deficiencies, and Helicobacter pylori: a new hypothesis.

Background: Previous findings for the Texas Neural Tube Defects Project suggested that while maternal access to nutrients is adequate, bioavailability of nutrients to the fetus is compromised in NTD-affected pregnancies. Helicobacter pylori could cause nutrient loss to the fetus. Folate, B12, and ferritin are depleted in H.

High school athletic departments as sentinel surveillance sites for community-associated methicillin-resistant staphylococcal infections.

Methicillin-resistant Staphylococcus aureus (MRSA) is an emerging infection in athletes. Our study assessed MRSA burden in Texas 4A and 5A high school athletic departments by contacting 447 licensed athletic trainers (LATs) regarding skin infections in athletes; 186 (41.6%) responded.

Exposure to fumonisins and the occurrence of neural tube defects along the Texas-Mexico border.

Along the Texas-Mexico border, the prevalence of neural tube defects (NTDs) among Mexican-American women doubled during 1990-1991. The human outbreak began during the same crop year as epizootics attributed to exposure to fumonisin, a mycotoxin that often contaminates corn. Because Mexican Americans in Texas consume large quantities of corn, primarily in the form of tortillas, they may be exposed to high levels of fumonisins.

Iron status indicators in women with prior neural tube defect-affected pregnancies.

Objectives: Iron deficiency is the most common nutrient deficiency in pregnant women and has been linked to negative impacts on the fetus. We describe the association of various iron-deficiency indices with risk of neural tube defect (NTD) among a high-risk Mexican-American population.

Methods: The study included 158 case-women (NTD-affected pregnancies) and 189 control-women (normal births) who were residents of the 14 Texas-Mexico border counties and delivered or terminated pregnancies during 1995-2000.

Maternal exposure to arsenic, cadmium, lead, and mercury and neural tube defects in offspring.

Arsenic, cadmium, lead, and mercury are neurotoxins, and some studies suggest that these elements might also be teratogens. Using a case-control study design, we investigated the relation between exposure to these heavy metals and neural tube defects (NTDs) in offspring of Mexican-American women living in 1 of the 14 Texas counties bordering Mexico. A total of 184 case-women with NTD-affected pregnancies and 225 control-women with normal live births were interviewed about their environmental and occupational exposures during the periconceptional period.

Exposure to polychlorinated biphenyls and risk of neural-tube defects in a Mexican American population.

The authors examined the association between maternal polychlorinated biphenyl (PCB) levels and risk of neural tube defects (NTDs) in Mexican American women with NTD-affected pregnancies who resided in the 14 Texas-Mexico border counties during 1995-2000 (cases). Controls were randomly selected from study area women delivering normal live births. For PCB congeners with sufficient numbers of detectable values (PCB 99, 101, 110, 118, 138, 153, 180), there was little association between the proportions with detectable PCB levels in cases and controls.

The wound care team: a new source of group a streptococcal nosocomial transmission.

Background: In August 2001, the Centers for Disease Control and Prevention (CDC) notified the Texas Department of Health (TDH) of an unusually high number of wounds infected with group A streptococci (GAS) in an acute care facility. The TDH initiated an investigation, ultimately identifying 28 cases of non-pharyngeal, non-community-acquired GAS that had occurred between December 2000 and August 2001 and resulted in 3 deaths and 4 nonfatal cases of invasive disease. Ten specimens were sent to the CDC for emm typing; all isolates were emm type 114.

Implementation and outcomes of recommended folic acid supplementation in Mexican-American women with prior neural tube defect-affected pregnancies.

Background: Upon discovering an NTD incidence rate of 27/10,000 in a Texas border county, the Texas Department of Health initiated folic acid intervention for prevention of recurrent NTDs in this predominantly Mexican-American population. This paper describes compliance of this population with USPHS folic acid recommendations and the impact of supplementation on pregnancy outcomes.

Methods: Based upon information from active surveillance, field teams personally contacted women having NTD-affected pregnancies to enroll them in FA intervention.

The effect of fever, febrile illnesses, and heat exposures on the risk of neural tube defects in a Texas-Mexico border population.

Background: Hyperthermia produces neural tube defects (NTDs) in a variety of animal species. Elevated maternal body temperatures may also place the developing human embryo at risk. We examined the relation between maternal hyperthermia and the development of NTDs in a high-risk Mexican-American population.

Dietary nitrites and nitrates, nitrosatable drugs, and neural tube defects.

Background: Amine-containing (nitrosatable) drugs can react with nitrite to form N-nitroso compounds, some of which are teratogenic. Data are lacking on whether dietary intake of nitrates and nitrites modifies the association between maternal nitrosatable drug exposure and neural tube defects (NTDs) in offspring.

Methods: We examined nitrosatable drug exposure and NTD-affected pregnancies in relation to dietary nitrite and total nitrite intake in a case-control study of Mexican American women.

Prevalence of craniorachischisis in a Texas-Mexico border population.

Background: The most severe neural tube defect (NTD), craniorachischisis, is characterized by anencephaly confluent with spina bifida open from the cervical to the lumbar region. We describe the prevalence of craniorachischisis among the Texas-Mexico border population during the period 1993-1999.

Methods: An active surveillance system identified all clinically apparent NTD-affected fetuses and infants born to mothers residing and delivering in any of the 14 Texas-Mexico border counties.
