Disparities in infertility workup costs across the United States.

Objective: To investigate cost disparities of infertility diagnostic tests across the United States.

Design: Cross-sectional study analyzing costs for recommended infertility diagnostic tests, including hormone tests (follicle stimulating hormone, luteinizing hormone, estradiol, and progesterone), semen analysis, transvaginal ultrasound, and hysterosalpingogram. Data were sourced from consumer cost claims repositories for five most populous cities per state, categorized into four regions (Midwest, South, West, and Northeast) as per US Census Bureau classifications.

Voxel-based lesion symptom mapping localizes residual visual function in hemianopia.

Damage to the primary visual cortex (V1) results in visual field deficits on the contralateral side of the world corresponding to the damaged region. Patients with such loss nonetheless show varying residual vision within this apparently blind region, with the neural mechanisms underlying this ability obscured by small study populations. We identified lesions on structural scans from 39 patients (12 female) with hemianopia and occipital lobe damage.

A national Australian Congenital Heart Disease registry; methods and initial results.

Background: Although several National Data Registries for Congenital Heart Disease (CHD) exist, few are comprehensive and contemporary. A National Australian CHD Registry has been developed that aims to redress this by creating the first comprehensive data collection for CHD children and adults, initially across Australia.

Methods: We defined and collected a minimum dataset of demographics, diagnoses, and procedures from people with CHD presenting at participating quaternary CHD services Australia-wide.

Resident Performance on the Obstetrics and Gynecology In-Training Examination After Implementation of a New Academic Curriculum.

Background The goals of the annual Council on Resident Education in Obstetrics and Gynecology In-Training Examination (CREOG-ITE) are to provide residents with an assessment of their knowledge and program directors an assessment of their residency programs. Research has shown that a score greater than 200 is correlated with passing the qualifying board examination. We observed a substantial number of our residents were not performing well on the exam, which prompted the implementation of a new academic program aimed at determining the impact of an academic curriculum addition on CREOG-ITE scores in an American College of Graduate Medical Education (ACGME) accredited obstetrics and gynecology (OB/GYN) residency program.

Phosphorylation of HP1/Swi6 relieves competition with Suv39/Clr4 on nucleosomes and enables H3K9 trimethyl spreading.

Heterochromatin formation in Schizosaccharomyces pombe requires the spreading of histone 3 (H3) Lysine 9 (K9) methylation (me) from nucleation centers by the H3K9 methylase, Suv39/Clr4, and the reader protein, HP1/Swi6. To accomplish this, Suv39/Clr4 and HP1/Swi6 have to associate with nucleosomes both nonspecifically, binding DNA and octamer surfaces and specifically, via recognition of methylated H3K9 by their respective chromodomains. However, how both proteins avoid competition for the same nucleosomes in this process is unclear.
