Recurrence of Ganglion Cysts Following Re-excision

Previous studies have examined the recurrence of ganglion cysts after surgical excision at a rate of 4 to 40%. However, recurrence after revision surgical excision is unknown. The purpose of this study was to define the incidence of recurrent ganglion cysts in patients who underwent a 2nd excisional procedure.https://jdc.jefferson.edu/cwicposters/1032/thumbnail.jp

Exercise Beliefs During Pregnancy in a Predominantly Low-Income, Urban Minority Population

In 2002, and reaffirmed in 2009, The American College of Obstetricians and Gynecologists recommended that healthy pregnant women exercise for at least thirty minutes most days of the week. Exercise during a healthy pregnancy is safe and has many maternal and fetal benefits. Identified benefits include management of weight gain, improvement in mood, and preparation for labor. Previous research has evaluated women’s beliefs and practices of exercise in pregnancy, but it has focused on affluent, ethnic majority populations. This survey study was performed to assess beliefs about exercise in pregnancy in a predominantly low-income, urban minority population.https://jdc.jefferson.edu/cwicposters/1031/thumbnail.jp

Evolution in the bias of faint radio sources to z ~ 2.2

Quantifying how the baryonic matter traces the underlying dark matter distribution is key to both understanding galaxy formation and our ability to constrain the cosmological model. Using the cross-correlation function of radio and near-infrared galaxies, we present a large-scale clustering analysis of radio galaxies to z ~ 2.2. We measure the angular auto-correlation function of Ks90μJy to infer linear bias of radio galaxies in four redshift bins. We find that the bias evolves from b = 0.57 ± 0.06 at z ~ 0.3 to 8.55 ± 3.11 at z ~ 2.2. Furthermore, we separate the radio sources into subsamples to determine how the bias is dependent on the radio luminosity, and find a bias which is significantly higher than predicted by the simulations of Wilman et al., and consistent with the lower luminosity but more abundant FR-I population having a similar bias to the highly luminous but rare FR-IIs. Our results are suggestive of a higher mass, particularly for FR-I sources than assumed in simulations, especially towards higher redshift.Peer reviewe
