Purpose:We compared urinary tract infection (UTI) symptom resolution rates at 7–10 days in symptomatic women randomized to treatment based on standard urine culture (SUC) versus expanded quantitative urine culture (EQUC) results.Materials and Methods:Women ≥18 years old who responded “yes” to “do you feel you have a UTI?” agreed to urethral catheterization and followup. Symptoms were assessed using the validated UTI Symptom Assessment (UTISA) questionnaire. Culture method was randomized 2:1 (SUC:EQUC); antibiotics were prescribed to women with positive cultures. The primary outcome, UTI symptom resolution, was determined 7–10 days following enrollment on all participants regardless of treatment.Results:Demographic data were similar between groups. Of the SUC and EQUC groups 63% and 74% had positive cultures (p=0.10), respectively. Of participants with positive cultures 97% received antibiotics. Primary outcome data were provided by 215 of 225 participants (SUC 143 [95%], EQUC 72 [97%]). At the primary outcome assessment, 64% and 69% in the SUC and EQUC groups, respectively, reported UTI symptom resolution (p=0.46); UTISA scores improved from baseline in the EQUC arm compared to the SUC arm (p=0.04). In the subset of women predominated by non-Escherichia coli (76), there was a trend toward more symptom resolution in the EQUC arm (21%, p=0.08).Conclusions:Symptom resolution was similar for the overall population (E. coli and non-E. coli) of women treated for UTI symptoms based on SUC or EQUC. Although the sample size limits conclusions regarding the utility of EQUC in women with non-E. coli uropathogens, the detected trend indicates that this understudied clinical subset warrants further study.

All-trans-retinoic acid (ATRA) and arsenic trioxide (ATO) induce differentiation and apoptosis in acute promyelocytic leukemia (APL) cells. Here we investigated the role and regulation of death-associated protein-5 (DAP5/p97/NAT1), a novel inhibitor of translational initiation, in APL cell differentiation and apoptosis. We found that ATRA markedly induced DAP5/p97 protein and gene expression and nuclear translocation during terminal differentiation of APL (NB4) and HL60 cells but not differentiation-resistant cells (NB4.R1 and HL60R), which express very low levels of DAP5/p97. At the differentiation inducing concentrations, ATO (<0.5 microM), dimethyl sulfoxide, 1,25-dihydroxy-vitamin-D3, and phorbol-12-myristate 13-acetate also significantly induced DAP5/p97 expression in NB4 cells. However, ATO administered at apoptotic doses (1-2 microM) induced expression of DAP5/p86, a proapoptotic derivative of DAP5/p97. ATRA and ATO-induced expression of DAP5/p97 was associated with inhibition of the phosphatidylinositol 3-kinase (PI3K)/Akt pathway. Furthermore, DAP5/p97 expression was upregulated by inhibition of the PI3K/Akt/mammalian target of rapamycin (mTOR) pathway via LY294002 and via rapamycin. Finally, knockdown of DAP5/p97 expression by small interfering RNA inhibited ATRA-induced granulocytic differentiation and ATO-induced apoptosis. Together, our data reveal new roles for DAP5/p97 in ATRA-induced differentiation and ATO-induced apoptosis in APL and suggest a novel regulatory mechanism by which PI3K/Akt/mTOR pathway inhibition mediates ATRA- and ATO-induced expression of DAP5/p97.

OVX mice persisted with increased voiding frequency after LPS. Urothelial genes that could mediate this voiding behavior include IL6, COX-2, and S-adenosylmethionine decarboxylase.

Objectives We aimed to investigate the effect of music listening on preoperative anxiety compared with usual care in patients undergoing pelvic reconstructive surgery. Methods Patients scheduled for pelvic reconstructive surgery were enrolled on the day of surgery. Participants were randomized to either the usual care (control group) or to music listening on headphones (music group) before their surgery. Participants completed the Spielberg State-Trait Anxiety Inventory form Y1 to measure baseline state anxiety levels before surgery and again after 30 minutes of usual care or music listening. The primary outcome was the change in state anxiety score as measured by the State-Trait Anxiety Inventory form Y1. Results Sixty-nine women completed the study (35 assigned to the control group and 34 assigned to the music group). Analysis of the primary outcome included 66 participants (34 in the control group and 32 in the music group). Improvement in state anxiety was significantly better for patients assigned to music listening (−6.69; SD, 6.98) than for patients assigned to the control group (−1.32; SD, 8.03; P = 0.01). Six weeks postoperatively, patients in the music group (n = 29) reported higher overall satisfaction when compared with those in the control group (n = 31, P = 0.03). Conclusion Patients undergoing pelvic reconstructive surgery present with moderate anxiety on the day of surgery. Allowing patients to listen to their preferred music is a simple intervention that may lower preoperative anxiety and improve satisfaction in this patient population.
