Weranja Ranasinghe, Daniel D Shapiro, Miao Zhang, Tharakeswara Bathala, Nora Navone, Timothy C Thompson, Bradley Broom, Ana Aparicio, Shi-Ming Tu, Chad Tang, John W Davis, Louis Pisters, Brian F Chapin,

Ductal adenocarcinoma (DAC) is the most common variant histological subtype of prostate carcinoma and has an aggressive clinical course. DAC is usually characterized and treated as high-risk prostatic acinar adenocarcinoma (PAC). However, DAC has a different biology to that of acinar disease, which often poses a challenge for both diagnosis ... Read more >>

Causal Diagram Techniques for Urologic Oncology Research.

Daniel D Shapiro, Pavlos Msaouel,

Large quantities of data are now available to medical researchers; however, observational studies are plagued by bias and confounding. Additionally, much of this research only speculates on variable associations, leaving prospective randomized clinical trials as the sole purveyors of claims about causal relations between variables. There has been a growing ... Read more >>

Neoadjuvant Therapy for Locally Advanced Renal Cell Carcinoma.

Mary E Westerman, Daniel D Shapiro, Christopher G Wood, Jose A Karam,

There has been strong interest in using neoadjuvant therapy to decrease recurrence rates and facilitate surgical resection in locally advanced renal cell carcinoma. To date, no evidence exists to support improvement in oncologic outcomes with neoadjuvant therapy. Likewise, although targeted therapies have shown efficacy in tumor downsizing, this does not ...

Do I need to see a urologist for my vasectomy? A comparison of practice patterns between urologists and family medicine physicians.

Natasza M Posielski, Daniel D Shapiro, Xing Wang, Brian V Le,

Urologists perform the majority of vasectomies in the United States; however, family medicine physicians (FMPs) perform up to 35%. We hypothesized that differences exist in practice patterns and outcomes between urologists and FMPs. Patients who underwent a vasectomy from 2010 to 2016 were identified. Postvasectomy semen analysis (PVSA) practices were ... Read more >>

Genetic analysis of the role of yfiR in the ability of Escherichia coli CFT073 to control cellular cyclic dimeric GMP levels and to persist in the urinary tract.

Erica L Raterman, Daniel D Shapiro, Daniel J Stevens, Kevin J Schwartz, Rodney A Welch,

During urinary tract infections (UTIs), uropathogenic Escherichia coli must maintain a delicate balance between sessility and motility to achieve successful infection of both the bladder and kidneys. Previous studies showed that cyclic dimeric GMP (c-di-GMP) levels aid in the control of the transition between motile and nonmotile states in E. ... Read more >>
