Importance: Urogenital changes associated with menopause are now classified as genitourinary syndrome of menopause (GSM), which includes symptoms of urgency, frequency, dysuria, and recurrent urinary tract infections for which the recommended treatment is estrogen. However, the association between menopause and urinary symptoms and the efficacy of hormone therapy for these symptoms is uncertain.

Objective: Our objective was to define the relationship between menopause and urinary symptoms including dysuria, urgency, frequency, recurrent urinary tract infections (UTIs), and urge and stress incontinence by conducting a systematic review of the effects of hormone therapy (HT) for urinary symptoms in perimenopausal and postmenopausal women.

Purpose: We aimed to understand the reasons patients choose to pursue third-line overactive bladder (OAB) therapy.

Materials And Methods: We conducted a mixed methods study that included patient interviews and survey data. Eligible patients were diagnosed by symptoms, had tried behavioral modifications, and OAB medications enrolled from October 2018 to August 2019.

Objective: To compare the incidence of postoperative pain after suture- or mesh-based sacrospinous ligament suspension (SSLS).

Methods: In a retrospective study, data were reviewed from patients who underwent suture- or mesh-based SSLS at a center in Skokie, IL, USA, between 2006 and 2011. The primary outcome was self-reported postoperative pain scores (range 0-10) on the day of surgery (day 0) and 1 day later (day 1).

Introduction And Hypothesis: Here we describe anatomic and quality of life (QOL) outcomes of an anterior and apical compartment prolapse repair involving a reduced mesh implant size and apex-only fixation.

Methods: One hundred and fifteen patients undergoing the repair at a single urogynecology center were assessed using the Pelvic Organ Prolapse Quantification (POP-Q) and inpatient chart reviews. A horizontal incision eliminated overlap with the mesh, and each sacrospinous ligament was approached anteriorly by blunt dissection.

MITOSTATIN, a novel putative tumor suppressor gene induced by decorin overexpression, is expressed in most normal human tissues but is markedly down-regulated in advanced stages of mammary and bladder carcinomas. Mitostatin negatively affects cell growth, induces cell death and regulates the expression and activation levels of Hsp27. In this study, we demonstrated that ectopic expression of Mitostatin in PC3, DU145, and LNCaP prostate cancer cells not only induced a significant reduction in cell growth, but also inhibited migration and invasion.

The use of the transdermal contraceptive patch is associated with greater bioavailability of ethinyl estradiol (EE) compared with contraceptive vaginal ring or oral contraceptives (OC). We compared the influences of three contraceptive methods (OC, vaginal ring, and transdermal patch) on serum levels of coenzyme Q(10), alpha-tocopherol, gamma-tocopherol and total antioxidant capacity in premenopausal women. Blood samples from 30 premenopausal women who used hormonal contraception for at least 4 months were collected.

Unlabelled: Regular supply of fluoride ions to the oral environment is one of the prophylactic actions against dental caries. Fluorides, whose exogenous action combines with saliva properties, condition the anticariogenic effect. Fluoride ions exhibit high chemical activity, can alter the oral environment parameters and inhibit the activity of enzymes.

Centrin is an evolutionarily conserved 20 kDa, Ca+2-binding, calmodulin-related protein associated with centrioles and basal bodies of phylogenetically diverse eukaryotic cells. Earlier studies have shown that residual centrosomes of non-rodent mammalian spermatozoa retain centrin and, in theory, could contribute this protein for the reconstruction of the zygotic centrosome after fertilization. The present work shows that CEN2 and CEN3 mRNA were detected in germinal vesicle-stage (GV) oocytes, MII oocytes, and pre-implantation embryos from the two-cell through the blastocyst stage, but not in spermatozoa.

Transitional cell carcinoma of the bladder is a common tumor. While most patients presenting superficial disease can be expected to do well following treatment, still many patients will return to our office with muscle invasive and metastatic disease. Survival in advanced bladder cancer is less than 50%.

Major vault protein (MVP), also called lung resistance-related protein is a ribonucleoprotein comprising a major part (>70%) of the vault particle. The function of vault particle is not known, although it appears to be involved in multi-drug resistance and cellular signaling. Here we show that MVP is expressed in mammalian, porcine, and human ova and in the porcine preimplantation embryo.
