RESUMO

Postmenopausal women with ovary hormone deficiency (OHD) are subject to overactive bladder (OAB) symptoms. The present study attempted to elucidate whether low-intensity extracorporeal shock wave therapy (LiESWT) alters bladder angiogenesis, decreases inflammatory response, and ameliorates bladder hyperactivity to influence bladder function in OHD-induced OAB in human clinical trial and rat model. The ovariectomized (OVX) for 12 months Sprague-Dawley rat model mimicking the physiological condition of menopause was utilized to induce OAB and assess the potential therapeutic mechanism of LiESWT (0.12 mJ/mm2, 300 pulses, and 3 pulses/second). The randomized, single-blinded clinical trial was enrolled 58 participants to investigate the therapeutic efficacy of LiESWT (0.25 mJ/mm2, 3000 pulses, 3 pulses/second) on postmenopausal women with OAB. The results revealed that 8 weeks' LiESWT inhibited interstitial fibrosis, promoted cell proliferation, enhanced angiogenesis protein expression, and elevated the protein phosphorylation of ErK1/2, P38, and Akt, leading to decreased urinary frequency, nocturia, urgency, urgency incontinence, and post-voided residual urine volume, but increased voided urine volume and the maximal flow rate of postmenopausal participants. In conclusion, LiESWT attenuated inflammatory responses, increased angiogenesis, and promoted proliferation and differentiation, thereby improved OAB symptoms, thereafter promoting social activity and the quality of life of postmenopausal participants.

RESUMO

Background and Objectives: To evaluate the effects of low intensity extracorporeal shock wave therapy (LiESWT) on stress urinary incontinence (SUI). Materials and Methods: This investigation was a multicenter, single-blind, randomized-controlled trial study. Sixty female SUI patients were randomly assigned to receive LiESWT with 0.25 mJ/mm2 intensity, 3000 pulses, and 3 pulses/s, once weekly for a 4-week (W4) and 8-week (W8) period, or an identical sham LiESWT treatment without energy transmission. The primary endpoint was the changes in urine leakage as measured by a pad test and validated standardized questionnaires, while the secondary endpoint was the changes in a 3-day urinary diary among the baseline (W0), the W4 and W8 of LiESWT, and 1-month (F1), 3-month (F3), and 6-month (F6) follow-up after LiESWT. Results: The results showed that 4 weeks of LiESWT could significantly decrease urine leakage based on the pad test and validated standardized questionnaire scores, as compared to the sham group. Moreover, 8 weeks of LiESWT could significantly reduce urine leakage but increase urine volume and attenuate urgency symptoms, which showed meaningful and persistent improvement at W8, F1, F3, and F6. Furthermore, validated standardized questionnaire scores were significantly improved at W8, F1, F3, and F6 as compared to the baseline (W0). Conclusions: Eight weeks of LiESWT attenuated SUI symptoms upon physical activity, reduced urine leakage, and ameliorated overactive bladder symptoms, which implied that LiESWT significantly improved the quality of life. Our findings suggested that LiESWT could serve as a potentially novel and non-invasive treatment for SUI.

RESUMO

BACKGROUND: Cervical elongation is commonly associated with pelvic organ prolapse (POP). It was an identified risk for recurrent prolapse after hysteropexy, requiring additional surgeries. The aim of the study is to investigate the risk factors for uterine cervical elongation among women with POP. METHODS: In this single-center retrospective cohort study, women who underwent vaginal total hysterectomy for POP between 2014 and 2016 were collected. The cervical and total uterine lengths were measured by pathologists, while the ratio of cervical length to total uterine length were calculated. The cervical elongation is defined as corpus/cervix ratio ≤ 1.5. RESULTS: A total of 133 patients were enrolled in this study. Among these patients, 43 women had cervical elongation and 90 women had normal length of uterine cervix. We found that age > 65 years old (67.4% vs. 42.2%, p = 0.007), total vaginal length ≥ 9.5 cm (65.1% vs. 45.6%, p = 0.035), uterine weight < 51 gm (72.1% vs. 52.2%, p = 0.03), and Pelvic Organ Prolapse Distress Inventory 6 (POPDI-6) ≥ 12 (30.2% vs. 14.4%, p = 0.032) were associated with the risk of cervical elongation. There were no significant differences on preoperative urodynamic parameters in the two groups. CONCLUSION: The patient age > 65 years old, the total vaginal length of POP-Q system ≥ 9.5 cm, uterine weight < 51 g, and POPDI-6 ≥ 12 are independent risk factors of cervical elongation in women with POP. For women scheduled for pelvic reconstructive hysteropexy, concomitant cervical amputation should be considered.

RESUMO

Interstitial cystitis/bladder pain syndrome (IC/BPS) is not only a chronic urinary bladder pain syndrome but is also associated with multifactorial etiology. Our study aimed to test the hypothesis that IC/BPS is associated with subsequent increased risks of outpatient visits and hospitalizations. Using nationwide database, the diagnoses were based on the International Classification Codes (ICD-9-CM) (595.1) of at least three outpatient services during 2002-2008, (n = 27,990) and cystoscopic finding Hunner type and/or glomerulation with pre-audit criteria. All recruited cases monitored for subsequent outpatient visits and hospitalizations for 2 years, including all-cause and specialty-specific departments, were classified according to medical specialty and age group (<40, 40-60, ≥60 years of age). IC/BPS patients have more overall outpatient department (OPD) visits and an overall adjusted incidence rate ratio (IRR) of 1.64. As for specialty, IRRs were higher in psychiatry (2.75), Chinese medicine (2.01), and emergency medicine (2.00), besides urology and gynecology. The IRRs decreased as age advanced (2.01, 1.71, and 1.44, respectively), except for gynecology (2.42, 2.52, and 2.81). A similar phenomenon happens in hospitalization with IRR of 1.69. Due to claim data characteristics, whether ulcer type IC/BPS findings can be deductive to non-ulcer type remains inclusive. Current results indicate the impacts of healthcare burden in broad spectrum about IC/PBS patients. IC/BPS has been suggested to be associated with lower threshold of healthcare visits and some coexisting disease and is comprised of systemic dysregulation, and is beyond the scope of local bladder-urethra disease. Adequate recognition of associated or comorbid factors and possible recommendation or referral for IC/BPS patients can help provide better healthcare quality.

RESUMO

BACKGROUND: The present study attempted to investigate the therapeutic effect and duration of low intensity extracorporeal shock wave therapy (LiESWT) on overactive bladder (OAB) symptoms, including social activity and the quality of life (QoL). METHODS: In this prospective, randomized, single-blinded clinical trial, 65 participants with OAB symptom were randomly divided into receive LiESWT (0.25 mJ/mm2, 3000 pulses, 3 pulses/second) once a week for 8 weeks, or an identical sham LiESWT treatment without the energy transmission. We analyzed the difference in overactive bladder symptom score (OABSS) and 3-day urinary diary as the primary end. The secondary endpoint consisted of the change in uroflowmetry, post-voided residual (PVR) urine, and validated standardized questionnaires at the baseline (W0), 4-week (W4) and 8-week (W8) of LiESWT, and 1-month (F1), 3-month (F3) and 6-month (F6) follow-up after LiESWT. RESULTS: 8-week LiESWT could significantly decrease urinary frequency, nocturia, urgency, and PVR volume, but meaningfully increase functional bladder capacity, average voided volume and maximal flow rate (Qmax) as compared with the W0 in the LiESWT group. In addition, the scores calculated from questionnaires were meaningfully reduced at W4, W8, F1, F3, and F6 in the LiESWT group. CONCLUSIONS: Our results revealed that the therapeutic efficacy of LiESWT could improve voided volume and ameliorate OAB symptoms, such as urgency, frequency, nocturia, and urinary incontinence, and lasted up to 6 month of follow-up. Moreover, LiESWT treatment brought statistically significant and clinically meaningful improvements in social activity and QoL of patients. These findings suggested that LiESWT could serve as an alternative non-invasive therapy for OAB patients.

RESUMO

Overactive bladder (OAB) syndrome, including frequency, urgency, nocturia and urgency incontinence, has a significantly negative impact on the quality-of-life scale (QoL) and can cause sufferer withdrawal from social activities. The occurrence of OAB can result from an imbalance between the production of pro-oxidants, such as free radicals and reactive species, and their elimination through protective mechanisms of antioxidant-induced oxidative stress. Several animal models, such as bladder ischemia/reperfusion (I/R), partial bladder outlet obstruction (PBOO) and ovarian hormone deficiency (OHD), have suggested that cyclic I/R during the micturition cycle induces oxidative stress, leading to bladder denervation, bladder afferent pathway sensitization and overexpression of bladder-damaging molecules, and finally resulting in bladder hyperactivity. Based on the results of previous animal experiments, the present review specifically focuses on four issues: (1) oxidative stress and antioxidant defense system; (2) oxidative stress in OAB and biomarkers of OAB; (3) OAB animal model; (4) potential nature/plant antioxidant treatment strategies for urinary dysfunction with OAB. Moreover, we organized the relationships between urinary dysfunction and oxidative stress biomarkers in urine, blood and bladder tissue. Reviewed information also revealed the summary of research findings for the effects of various antioxidants for treatment strategies for OAB.

RESUMO

The unique merits of aptamers, including specificity, high binding affinity, easy cell internalization, and rapid tissue accumulation abilities, have led aptamer-drug conjugates to evolve into one of the most attractive strategies for targeted drug delivery purposes. Nevertheless, the critical role of linkers in regulating anticancer efficacy of these conjugates, especially those engineered by automated modular synthesis techniques, has been rarely explored. In this work, we utilized Sgc8c aptamer and combretastatin A4 to develop three conjugates with either a phosphodiester bond linker, a disulfide bond linker, or a carbamate linker to study their payload release mechanisms and the influence on anticancer efficacy. These investigations allowed us to identify the unique activation pathway of the phosphodiester bond linker that is activated by both nucleophilic attack of glutathione and degradation caused by phosphodiesterase, which is highly associated with the higher cytotoxicity of the conjugate. Importantly, the understanding of the chemistry of phosphodiester bond linker activation allowed us to further design another XQ-2d-CA4 conjugate that can induce pancreatic cancer cells apoptosis in a more efficient manner.

RESUMO

With the advance of minimally invasive surgery (MIS), the surgical trends of hysterectomy changed significantly during past 2 decades. Total number (age-standardized) of all types of hysterectomy decreased, which may be due to the availability of some other alternatives, e.g. hysteroscopy, laparoscopic myomectomy. However, laparoscopic hysterectomy (LH) still remains the mainstream of surgical treatment. LH significantly increases for benign gynecologic conditions in Taiwan and worldwide. The increase of LH was accompanied with decrease of TAH; VH kept stationary, and SAH increased slightly. The increase in popularity of LH and SAH; provides evidence of surgical trends and a paradigm shift for hysterectomy. This time-frame shift suggests LH has reached a u during the later years. Older patients tend to receive AH, while middle-aged women tend to receive LH. Oder surgeons tend to perform AH, while younger surgeons tend to perform LH. However, all type hysterectomy and LH were more commonly performed by older surgeons aged over 50 years. It means both patients and surgeons became older during the time-frames. The above phenomena may also happen due to less young surgeons entered in the gynecologic practice. Most of the LHs were performed by high-volume surgeons, however, there is a shift from high-volume, to medium- and low-volume surgeons. The above scenario may be due to the wide spread of LH techniques. Surgical volume has important impacts on both complications and costs. The high-volume surgeons have lower complications, which result in lower costs. In the future, how to increase the use of LH, to improve the training and monitoring system deserves more attentions.

RESUMO

Objectives: Low intensity extracorporeal shock wave therapy (Li-ESWT) has proven to be effective and safe for the treatment of various urological disorders including erectile dysfunction and chronic pelvic pain syndrome. In this study, we elucidated the therapeutic effect and possible mechanisms of Li-ESWT on diabetic bladder dysfunction (DBD) in a rat model. Materials and Methods: In all, thirty-two female Sprague-Dawley rats were divided into three groups: normal control (NC), diabetes mellitus (DM) control, and DM Li-ESWT. The two DM groups were given high fat diets for one month, followed by 2 intraperitoneal injections of streptozotocin (STZ) 30 mg/kg separated by one week. Body weight and fasting blood glucose were monitored every week. Only rats with fasting blood glucose 140 mg/dL or more were considered diabetic and used in the subsequent portions of the study. The Li-ESWTs were applied toward the pelvis of the rats twice a week for 4 weeks with energy flux density (EFD) 0.02 mJ/mm2, 500 shocks, at 3Hz. All rats underwent plasma insulin tolerance test, conscious cystometry, leak-point pressure (LPP) assessment, and immunohistochemical studies. Results: DM groups had significantly lower insulin sensitivity and higher body weight. Conscious cystometry also revealed voiding dysfunctions. In the DM Li-ESWT group, the rats had significantly improved voiding functions that were reflected in longer micturition intervals and higher LPP compared to DM control. Immunofluorescence in DM control groups showed increased tyrosine hydroxylase (TH) expression and decreased neuronal nitric oxide synthase (nNOS) expression in the longitudinal urethral smooth muscles. Besides, rats had dilations and deformities of suburothelium capillary network of the bladder, revealing the deterioration of the nerve function of the urethra and destruction of the vascularization of the bladder. However, the DM Li-ESWT group exhibited recovery of the nerve expression of the urethra and vascularization of bladder. Conclusions: Li-ESWT ameliorates the bladder dysfunction and urinary continence in the DBD rat model, reflected in restoration of the nerve expression of the urethra and the vascularization of the bladder. Non-invasive Li-ESWT could be an alternative therapeutic option for DBD.

RESUMO

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is an emerging disease. There has been a rapid increase in cases and deaths since it was identified in Wuhan, China, in early December 2019, with over 4,000,000 cases of COVID-19 including at least 250,000 deaths worldwide as of May 2020. However, limited data about the clinical characteristics of pregnant women with COVID-19 have been reported. Given the maternal physiologic and immune function changes during pregnancy, pregnant women may be at a higher risk of being infected with SARS-CoV-2 and developing more complicated clinical events. Information on severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) may provide insights into the effects of COVID-19's during pregnancy. Even though SARS and MERS have been associated with miscarriage, intrauterine death, fetal growth restriction and high case fatality rates, the clinical course of COVID-19 pneumonia in pregnant women has been reported to be similar to that in non-pregnant women. In addition, pregnant women do not appear to be at a higher risk of catching COVID-19 or suffering from more severe disease than other adults of similar age. Moreover, there is currently no evidence that the virus can be transmitted to the fetus during pregnancy or during childbirth. Babies and young children are also known to only experience mild forms of COVID-19. The aims of this systematic review were to summarize the possible symptoms, treatments, and pregnancy outcomes of women infected with COVID-19 during pregnancy.

RESUMO

BACKGROUND/PURPOSE: To investigate the effects of simulated childbirth on the gene expression of parasympathetic muscarinic, purinergic (P2X), and neurokinin receptors of lower urinary tract in rats. METHODS: In all, twenty-four primiparous pregnant Sprague-Dawley female rats were equally divided into three groups: (1). Control group; 8 rats, (2) intra-vaginal balloon dilation for 2 h group; 8 rats, (3) and for 4 h group; 8 rats. After balloon dilatation for 4 months, all rats were sacrificed. We analyzed the gene expression of parasympathetic muscarinic, purinergic (P2X), and neurokinin receptors by real-time quantitative PCR (q-PCR). We quantified pro-inflammatory cytokines of TNF-α and IL-6 by Enzyme-linked immunosorbent assays (ELISA). The urodynamic parameters and micturition frequency by cystometry (CMG) were recorded. RESULTS: Our results showed that the balloon dilation significantly increased micturition frequency and modified peak micturition pressure compare to those in the control groups. Balloon dilation significantly decreased voiding interval and bladder volume compared to those in the control groups. Gene expressions of M3 muscarinic, P2X3 purinergic receptors, and significantly increased following balloon dilation for 2 hours and 4 hours than those in the control group. In addition, we found that NK1R and NK3R receptors were significantly decreased after balloon dilation compare to control group. The marked increase of TNF-α and IL-6 were also seen in the 2 balloon groups. CONCLUSION: The results of our study suggested that birth trauma may impair the function of urinary tract, this being partly related to the changes in the gene expression of the neurotransmitter receptors of the lower urinary tract.

RESUMO

The study aims to evaluate the effectiveness of local injection of autologous platelet rich plasma (A-PRP) as a treatment for women suffering from stress urinary incontinence (SUI). In a prospective intervention study, twenty consecutive women suffering from SUI were treated with A-PRP injection at anterior vaginal wall where mid-urethra locates. Self-reported questionnaires were used to measure pre-treatment, 1 month and 6 months post-treatment symptom severity. Secondary outcomes of sexual function and treatment effect sorted by age were analyzed with valid statistical methods. A-PRP is effective in relieving SUI symptoms at both 1 month and 6 months post-treatment without significant adverse reactions reported. It seems to have a trend that treatment success rate with cured and improved symptoms was slightly higher in the younger group, although it did not reach statistical significance (P = 0.07). No significant changes in sexual function before and after the treatment were reported by the patients. This pilot study is the first to report A-PRP treatment effect for SUI in women. The result suggested that A-PRP is a considerable treatment option for mild to moderate SUI cases. It also opens up further research opportunities for A-PRP's clinical applications.

RESUMO

OBJECTIVE: Clinical outcomes of 500 high-intensity focused ultrasound (HIFU)-treated uterine fibroids and adenomyosis are analyzed and presented. MATERIALS AND METHODS: This is a retrospective cross-sectional analysis from a single tertiary medical center. From April 2015 to October 2018, 546 cases were enrolled for the study. After excluding 46 patients with less than 3 months of follow-up period, there were 404 fibroids, 149 adenomyosis and 53 mixed conditions entered for analysis. The patients' uterine fibroids and adenomyosis were treated by HIFU according to Chongqing Haifu protocol, with 12 cm diameter transducer of focal length 10-16  cm at 0.8 or 1.6 MHz T2-weight MRI imaging was rendered prior to and 3 month post treatment to assess lesion volume change using non-perfusion volume, which was the primary outcome. Secondary outcomes including quality of life, subjective satisfaction, adverse events and pregnancy rate were determined using self-reported questionnaires. The mean follow up period ranged from 3 to 38 months with an average of 21 months. RESULTS: Three months after HIFU-treated uterine fibroids and adenomyosis, the lesion size reduced 40.2% and 46.3%, respectively. Symptoms all improved with better quality of life for the fibroid group, while those with adenomyosis or combined diseases benefit the most from pain control. Serum CA125 decreased significantly for all studied groups, and LDH only showed improvement for fibroids group. Number of adverse events is comparable to Chongqing data (approximately 10.2%), with mostly mild and self-resolving conditions. No permanent sequelae or death was documented. Twelve pregnancies are reported in this cohort. CONCLUSION: HIFU is safe and effective in treating uterine fibroids and adenomyosis. The results are reproducible if standardized treatment schedules are followed. It is a promising treatment alternative with the advantages of precision, non-invasiveness, rapid recovery and readiness for pregnancy.

RESUMO

OBJECTIVE: To identify factors associated with voiding dysfunction after Uphold™ transvaginal mesh (TVM) repair in women with pelvic organ prolapse (POP). STUDY DESIGN: We performed a retrospective analysis of 110 women with symptomatic pelvic organ prolapse (POP), anterior vaginal wall prolapse and/or apical prolapse (stage II to IV) who were scheduled for Uphold™ mesh surgery from September 2015 through December 2016. All subjects underwent urinalyses, UDI-6, IIQ-7, ICI-Q, POPDI-6, and pelvic examinations using the POP quantification (POP-Q) staging system before and after surgeries, with follow-up durations ranging from 24-36 months. RESULTS: A total of 12 (10.9 %) of 110 women reported voiding dysfunction after Uphold™ mesh surgery. Using univariate analysis, there were no differences in body mass index and urodynamic parameters between normal voiding group and dysfunctional voiding group (P > 0.05). However, in patients aged above 71, POPDI-6 score≧13, preoperative concomitant urinary hesitancy, and incomplete emptying were found to be significant predictors of voiding dysfunction following Uphold™ mesh surgeries (P < 0.05). CONCLUSION: In patients aged above 71, POPDI-6 score≧13, preoperative concomitant urinary hesitancy, and incomplete emptying were significant predictors of voiding dysfunction after Uphold™.

RESUMO

OBJECTIVE: This study aimed to compare the outcomes of magnetic resonance-guided (MR-g) high-intensity focused ultrasound (HIFU) with uterine artery embolization (UAE) for the treatment of uterine myoma. MATERIALS AND METHODS: A systematic literature review and meta-analysis was conducted using database searches of Medline, Cochrane, EMBASE, and Google Scholar. Articles were searched through March 25, 2020. Outcomes of interest were Symptom Severity Score (SSS), Health-related Quality of Life (HRQoL), re-intervention rate, and rate of adverse reactions in patients with uterine myoma. RESULTS: Four studies were included with a total of 207 patients with uterine myomas who received MR-g HIFU and 201 who received UAE. UAE was associated with a greater reduction in SSS, improved HRQoL, and a significantly lower re-intervention rate compared with MR-g HIFU in 3 of 4 included studies. No significant differences were found in the incidence and severity of adverse events between treatment arms in one study, but differences were observed in the percentage of adverse reactions in another. CONCLUSION: Published evidence suggests that the efficacy of MR-g HIFU may not be superior to that of UAE in the treatment of uterine myoma.

RESUMO

This retrospective cohort study aims to assess the clinical and urodynamic outcomes of single-incision mesh surgery with the Uphold system. The medical records of 140 women with anterior and/or apical compartment prolapse stage 2 or greater who underwent Uphold mesh surgeries were reviewed. The clinical evaluation included a pelvic examination, a urodynamic study (UDS), and a personal interview to evaluate lower urinary tract symptoms (LUTS). After a follow-up time of 12-30 months, the anatomical reduction rates were 100% and 96.4% for the apical and anterior compartments, respectively, and these rates were similar across women with or without hysterectomy. All of the LUTS and several UDS parameters improved significantly. The continence rate in women with stress urinary incontinence (SUI) was improved if they also underwent a mid-urethral sling (MUS) operation. However, the continence rate did not differ between women with and without occult urodynamic stress incontinence who did not undergo a concomitant MUS operation. The rate of vaginal mesh extrusion was 2.8%, and this complication rarely occurred beyond the learning curve. In conclusion, the anatomic correction of the Uphold system was satisfactory with a low rate of mesh extrusion. Women with SUI would benefit from a concomitant MUS operation.

RESUMO

Objective: In the present clinical trial, we evaluated the therapeutic effects of low-intensity extracorporeal shockwave therapy (LiESWT) on overactive bladder (OAB). Methods: Female subjects with ages of 20-75 years and who have been clinically diagnosed with OAB were included in the study. The LiESWT (DUOLITH SD1 T-TOP, AG) applicator was placed on the suprapubic skin area and applied with an intensity of 0.25 mJ/mm2, 3000 pulses, and 3 pulses/second. To assess the therapeutic efficacy, all subjects were required to complete the validated OAB symptoms and life bothersome questionnaires, 3-day urinary diary, uroflowmetry, and post-voided residual urine (PVR) measurement at 4 weeks of LiESWT (W4), 8 weeks of LiESWT (W8), 1-month follow-up (F1), and 3-month follow-up (F3) after LiESWT. Result: 82 subjects with the mean age of 56.5 ± 1.2 years were enrolled. The questionnaire scores were significantly improved at W4, W8, F1, and F3 as compared to baseline data (W0). At W8, the mean values of functional bladder capacity were meaningfully increased. According to the 3-day urinary diary, daytime frequency, urgency, and nocturia were significantly decreased. The uroflowmetry results showed that the mean voided urine volume and the maximal flow rate (Q max) were noticeably increased. PVR volume was also significantly decreased. Conclusions: The data demonstrated that 8-week LiESWT ameliorated the OAB symptoms, promoted the uroflow parameters, and improved the quality of life (QoL) in OAB patients, suggesting that LiESWT might serve as an alternative noninvasive therapy for OAB.
