Physician-patient communication about overactive bladder: Results of an observational sociolinguistic study
<div><p>Introduction</p><p>Overactive bladder (OAB) and urinary incontinence are common problems that have significant impact on quality of life (QOL). Less than half of sufferers seek help from their physicians; many who do are dissatisfied with treatment and their physicians’ understanding of their problems. Little is known about the sociolinguistic characteristics of physician-patient communication about OAB in community practice.</p><p>Methods</p><p>An IRB-approved observational sociolinguistic study of dialogues between patients with OAB and treating physicians was conducted. Study design included semi-structured post-visit interviews, post-visit questionnaires, and follow-up phone calls. Conversations were analyzed using techniques from interactional sociolinguistics.</p><p>Results</p><p>Communication was physician- rather than patient-centered. Physicians spoke the majority of words and 83% of questions were closed-ended. The impact of OAB on QOL and concerns about and adherence to treatment were infrequently addressed by physicians, who were poorly aligned with patients in their understanding. These topics were addressed more frequently when open-ended questions successfully eliciting elaborated responses were used in ask-tell-ask or ask-tell sequences.</p><p>Discussion</p><p>Clinical dialogue around OAB is physician-centered; topics critical to managing OAB are infrequently and inadequately addressed. The use of patient-centered communication is correlated with more discussion of critical topics, and thus, more effective management of OAB.</p></div

Role of PECAM-1 (CD31) in neutrophil transmigration in murine models of liver and peritoneal inflammation
Platelet endothelial cell adhesion molecule-1 (PECAM-1) is thought to be critical for transendothelial migration of leukocytes, including neutrophils. Because neutrophil-mediated liver injury during endotoxemia is dependent on transmigration, we investigated the role of PECAM-1 in the pathophysiology of endotoxin-induced liver injury. Male C3Heb/FeJ mice were treated with galactosamine (Gal) and endotoxin (ET) (700 mg/kg Gal/100 μg/kg ET), and liver sections were stained for PECAM-1 expression. Control livers showed the presence of PECAM-1 on endothelial cells of large vessels but not in sinusoids. Gal/ET treatment did not change the expression pattern of PECAM- 1. Gal/ET-induced liver injury (area of necrosis: 38 ± 3%) was not attenuated by treatment with 3 mg/kg of the antimurine PECAM-1 antibody 2H8. The antibody had no effect on sequestration and transmigration of neutrophils in sinusoids or the margination of neutrophils in large vessels. In contrast, 2H8 inhibited glycogen-induced neutrophil migration into the peritoneum by 74%; this effect correlated with PECAM-1 expression in the intestinal vasculature. Thus PECAM-1 is neither expressed nor inducible in hepatic sinusoids and is consequently not involved in neutrophil transmigration in the liver during endotoxemia. On the other hand, expression of PE-CAM-1 in mesenteric veins is critical for peritoneal neutrophil accumulation
