1.  Management of the first in vitro fertilization cycle for unexplained infertility: a cost-effectiveness analysis of split in vitro fertilization-intracytoplasmic sperm injection 
Fertility and sterility  2013;100(5):1381-1388.
To determine the cost-effectiveness of split IVF-intracytoplasmic sperm injection (ICSI) for the treatment of couples with unexplained infertility.
Adaptive decision model.
Academic infertility clinic.
A total of 154 couples undergoing a split IVF-ICSI cycle and a computer-simulated cohort of women <35 years old with unexplained infertility undergoing IVF.
Modeling insemination method in the first IVF cycle as all IVF, split IVF-ICSI, or all ICSI, and adapting treatment based on fertilization outcomes.
Main Outcome Measure(s)
Live birth rate, incremental cost-effectiveness ratio (ICER).
In a single cycle, all IVF is preferred as the ICER of split IVF-ICSI or all ICSI ($58,766) does not justify the increased live birth rate (3%). If two cycles are needed, split IVF/ICSI is preferred as the increased cumulative live birth rate (3.3%) is gained at an ICER of $29,666.
In a single cycle, all IVF was preferred as the increased live birth rate with split IVF-ICSI and all ICSI was not justified by the increased cost per live birth. If two IVF cycles are needed, however, split IVF/ICSI becomes the preferred approach, as a result of the higher cumulative live birth rate compared with all IVF and the lesser cost per live birth compared with all ICSI.

2.  Use of Sea Stars to Study Basic Reproductive Processes 
Echinoderms are closely related to chordates and comprise a major group of invertebrate deuterostomes. They are broadcast spawners and as such, each female accumulates millions of eggs and oocytes. These cells are readily isolated, and are often large, clear, and surrounded by accessory cells and extracellular coverings that do not prevent access to the oocyte. Sea stars are one type of echinoderm. Their oocytes are stored in prophase of meiosis, and since the natural meiotic stimulus has been identified as 1-methyladenine, these cells can be induced to complete meiotic maturation as individuals, or synchronously en masse. Microinjection and culture of these cells is feasible using quantitative or repetitive methods so that hundreds of oocytes and eggs can be modified each hour. Experimentation on this organism is extensive over a rich history of reproductive and developmental biology so that new investigators can easily incorporate this organism into their repertoire of research. This chapter will highlight the fundamental protocols to enable a new investigator to perform an array of approaches on this organism, including oocyte isolation, microinjection, and even single cell quantitative PCR.

4.  Epidemiologic Responses to Anthrax Outbreaks: A Review of Field Investigations, 1950–2001 
Emerging Infectious Diseases  2002;8(10):1163-1174.
We used unpublished reports, published manuscripts, and communication with investigators to identify and summarize 49 anthrax-related epidemiologic field investigations conducted by the Centers for Disease Control and Prevention from 1950 to August 2001. Of 41 investigations in which Bacillus anthracis caused human or animal disease, 24 were in agricultural settings, 11 in textile mills, and 6 in other settings. Among the other investigations, two focused on building decontamination, one was a response to bioterrorism threats, and five involved other causes. Knowledge gained in these investigations helped guide the public health response to the October 2001 intentional release of B. anthracis, especially by addressing the management of anthrax threats, prevention of occupational anthrax, use of antibiotic prophylaxis in exposed persons, use of vaccination, spread of B. anthracis spores in aerosols, clinical diagnostic and laboratory confirmation methods, techniques for environmental sampling of exposed surfaces, and methods for decontaminating buildings.
