Evidence-based review of nonantibiotic urinary tract infection prevention strategies for women: a patient-centered approach.

PURPOSE OF REVIEW: There is a growing interest in nonantibiotic prevention strategies for recurrent urinary tract infections (rUTIs). Our objective is to provide a focused, pragmatic review of the latest evidence. RECENT FINDINGS: Vaginal estrogen is well tolerated and effective for preventing rUTI in postmenopausal women. Cranberry supplements at sufficient doses are effective in preventing uncomplicated rUTI. Methenamine, d -mannose, and increased hydration all have evidence to support their use, although the evidence is of somewhat variable quality. SUMMARY: There is sufficient evidence to recommend vaginal estrogen and cranberry as first-line rUTI prevention strategies, particularly in postmenopausal women. Prevention strategies can be used in series or in tandem, based on patient preference and tolerance for side effects, to create effective nonantibiotic rUTI prevention strategies.

Representation in Online Prostate Cancer Content Lacks Racial and Ethnic Diversity: Implications for Black and Latinx Men.

PURPOSE: Black men have the highest incidence and mortality from prostate cancer (PCa) and lower quality of life compared to other U.S. racial groups. Additionally, more Latinx men are diagnosed with advanced disease and fewer receive guideline-concordant care. As many men seek medical information online, high-quality information targeting diverse populations may mitigate disparities. We examined racial/ethnic representation and information quality in online PCa content. MATERIALS AND METHODS: We retrieved 150 websites and 150 videos about "prostate cancer" using the most widely used search engine (Google) and social network (YouTube). We assessed quality of health information, reading level, perceived race/ethnicity of people featured in the content and discussion of racial/ethnic disparities. RESULTS: Among 81 websites and 127 videos featuring people, 37% and 24% had perceived Black representation, and racial/ethnic disparities were discussed in 27% and 17%, respectively. Among 1,526 people featured, 9% and 1% were perceived as Black and Latinx, respectively. No content with Black or Latinx representation was high quality, understandable, actionable and at the recommended reading level. CONCLUSIONS: Black and Latinx adults are underrepresented in online PCa content. Online media have significant potential for public education and combating health disparities. However, most PCa content lacks diversity and is not readily understandable.

Sonographic evaluation for intra-abdominal hemorrhage after cesarean delivery.

PURPOSE: To evaluate whether intra-abdominal hemorrhage is visible on a modified focused assessment with sonography for trauma (FAST) examination in stable obstetrics patients after a nonemergent cesarean delivery. METHODS: This was a prospective observational study of patients who underwent nonemergent cesarean delivery at a single institution. Patients provided written informed consent to participate in the study preoperatively and underwent a modified FAST examination in the recovery room within 2 hours of completion of surgery. A sonographic examination was considered positive for hemorrhage if an anechoic pocket consistent with free fluid was present. RESULTS: One hundred patients underwent suprapubic and bilateral upper-quadrant sonographic evaluations. The mean (±SD) time of the evaluation was 74.2 ± 36 minutes after the end of surgery. Among the 100 sonographic examinations of each upper quadrant, 194 (97.0%) were negative, 5 (2.5%) were indeterminate, and 1 (0.5%) was positive for fluid. All suprapubic sonographic examinations were considered inadequate. CONCLUSIONS: Sonographic evaluation immediately after cesarean delivery is feasible in most patients and was overwhelmingly negative for intra-abdominal hemorrhage in a group of patients who did not require reoperation or unexpected blood transfusion.

Wealth of Knowledge and Passion: Patient Perspectives on Vaginal Estrogen as Expressed on Reddit.

OBJECTIVE: To qualitatively analyze the knowledge, attitudes, and beliefs of women regarding genitourinary syndrome of menopause (GSM) and vaginal estrogen therapy as expressed on Reddit, a public, anonymous internet forum for discussion and information sharing. METHODS: "r/menopause," a Subreddit with >30,000 subscribers, was queried for "vaginal estrogen" to collect postings related to vaginal estrogen in October 2022. Posts were analyzed qualitatively by 2 independent researchers. The principles of grounded theory were applied, and preliminary themes were generated. These themes were used to derive emergent concepts. RESULTS: Sixty-seven unique posts with 1101 responses were analyzed. Qualitative analysis revealed 5 preliminary themes: (1) questions regarding medication usage, (2) medication side effects, (3) medication alternatives, (4) frustration with the medical system, and (5) seeking validation for symptoms and experiences. Three emergent concepts were derived: (1) women experience bothersome side effects from menopause, and they desire compassionate and effective medical treatment; (2) women are engaged and active participants in their health and health care decisions; and (3) women perceive that their concerns are not taken seriously and seek validation for their medical conditions. CONCLUSION: Peri- and post-menopausal women have many questions and concerns about the condition of GSM and vaginal estrogen as treatment. They also have a broad range of frustrations including access to health care and questions about the usage of vaginal estrogen. By better understanding patient perspectives, physicians can better meet women's needs and improve care for GSM.

Clinical Outcomes of a Combined Robotic, Transabdominal, and Open Transperineal Approach for Anastomotic Posterior Urethroplasty.

Background: Robotic pelvic surgery is being increasingly utilized for reconstruction proximal to the genitourinary diaphragm. We describe a combined robotic, transabdominal, and open transperineal approach for complex anastomotic posterior urethroplasty. Materials and Methods: We performed a multi-institutional retrospective study of patients who underwent anastomotic posterior urethroplasty by a combined robotic, transabdominal, and open transperineal approach between January 2012 and December 2018. Patient demographics; preoperative, intraoperative, and postoperative clinical data; and complications were reviewed. Urethroplasty success, de novo stress urinary incontinence (SUI), and de novo erectile dysfunction (ED) were evaluated. Results: Twelve patients were identified with a mean follow-up of 596 (range 73-1618) days. Mean patient age was 65.9 (range 53.4-76.8). Reconstruction required corporal splitting, prostatectomy, and gracilis muscle flap use in one (8.3%), eight (66.7%), and four (33.3%) patients, respectively. Postoperative urinary leak, thromboembolic event, and wound abscess occurred in one (8.3%), one (8.3%), and two (16.7%) patients, respectively. Stenosis recurrence occurred in two patients (16.7%) at a mean 187.5 (20-355) postoperative days. De novo ED and de novo SUI were reported in two (16.7%) and four (33.3%) patients, respectively. Nine patients (75.0%) underwent placement of an artificial urinary sphincter at a mean interval of 359.2 (111-1456) days after the index procedure, with no subsequent erosion. Conclusions: Complex posterior urethroplasty by a combined robotic, transabdominal and open transperineal approach is associated with success and complications rates that are comparable to open techniques and may allow for adjunctive procedures such as prostatectomy. This technique allows for the reconstruction of posterior urethral stenoses that would otherwise have been managed conservatively or with urinary diversion.

Access to infertility services: characterizing potentially infertile men in the United States with the use of the National Survey for Family Growth.

OBJECTIVE: To characterize the population of subfertile and infertile men in the United States who lack access to infertility services. DESIGN: Analysis of the 2011-2013, 2013-2015, and 2015-2017 waves of the National Survey for Family Growth (NSFG) dataset. SETTING: Not applicable. PATIENT(S): Noninstitutionalized civilian men, ages 15-45 years, who were married or lived with a woman and had not undergone a vasectomy. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE(S): Access to infertility services. RESULT(S): Compared with people who had used infertility services, unevaluated men who self-reported as infertile or subfertile were younger, had lower household incomes, were less educated, and were less likely to be married. Unevaluated infertile men were less likely to have a regular place where they received health care, were more likely to be uninsured, and had a poorer perception of their personal health. On multivariable logistic regression analysis, average household income, marital status, education level, and current insurance status remained significant. CONCLUSION(S): Infertile men who had not used infertility services were less educated, were less likely to have been married, and had a lower household income and private insurance rate compared with men who had used infertility services. These demographic and health care utilization differences can help inform public policy related to fertility.

Men Who Have Undergone Vasectomy are Healthier Than Non-sterilized Fertile Men: An Analysis of the Nation Survey for Family Growth.

OBJECTIVE: To evaluate the health status of men who have undergone vasectomy versus nonsterilized fertile men. METHODS: Using the National Survey for Family Growth from 2002 to 2017, univariate and multivariate analyses were performed on demographic and health data, including health status and health care utilization. RESULTS: Men who have undergone vasectomy are more likely to be older, healthier, have more children, identify as non-Hispanic white, be married, have a higher level of education, earn a higher mean household income, and were more likely to be privately insured than non-sterilized fertile men. On multivariate analysis, men who underwent vasectomy had a better health status despite being older. CONCLUSION: There are significant socioeconomic and health differences between men who elect vasectomy and non-sterilized fertile men. These differences should be considered when considering using sterilized men as a proxy for proven fertile men in epidemiological studies.

A Multi-Institutional Experience With Robotic Appendiceal Ureteroplasty.

OBJECTIVE: To report a multi-institutional experience with robotic appendiceal ureteroplasty. METHODS: This is a retrospective review of 13 patients undergoing right appendiceal flap ureteroplasty at 2 institutions between April 2016 and October 2019. The primary endpoint was surgical success defined by the absence of flank pain and radiographic evidence of ureteral patency. RESULTS: Eight of 13 (62%) underwent appendiceal onlay while 5/13 (38%) underwent appendiceal interposition. Mean length of stricture was 6.5 cm (range 1.5-15 cm) affecting anywhere along the right ureter. Mean operative time was 337 minutes (range 206-583), mean estimated blood loss was 116 mL (range 50-600), and median length of stay was 2.5 days (range 1-9). Balloon dilation was required in 1/12 (8%). One patient died on postoperative day 0 due to a sudden cardiovascular event. Otherwise, there were no complications (Clavien-Dindo > 2) within 30 days from surgery. At a mean follow up of 14.6 months, 11/12 (92%) were successful. CONCLUSION: Robotic appendiceal ureteroplasty for right ureteral strictures is a versatile technique with high success rates across institutions.

Effects of oxytocin and vasopressin on the neural response to unreciprocated cooperation within brain regions involved in stress and anxiety in men and women.

Anxiety disorders are characterized by hyperactivity in both the amygdala and the anterior insula. Interventions that normalize activity in these areas may therefore be effective in treating anxiety disorders. Recently, there has been significant interest in the potential use of oxytocin (OT), as well as vasopressin (AVP) antagonists, as treatments for anxiety disorders. In this double-blind, placebo-controlled, pharmaco- fMRI study, 153 men and 151 women were randomized to treatment with either 24 IU intranasal OT, 20 IU intranasal AVP, or placebo and imaged with fMRI as they played the iterated Prisoner's Dilemma game with same-sex human and computer partners. In men, OT attenuated the fMRI response to unreciprocated cooperation (CD), a negative social interaction, within the amygdala and anterior insula. This effect was specific to interactions with human partners. In contrast, among women, OT unexpectedly attenuated the amygdala and anterior insula response to unreciprocated cooperation from computer but not human partners. Among women, AVP did not significantly modulate the response to unreciprocated cooperation in either the amygdala or the anterior insula. However, among men, AVP attenuated the BOLD response to CD outcomes with human partners across a relatively large cluster including the amygdala and the anterior insula, which was contrary to expectations. Our results suggest that OT may decrease the stress of negative social interactions among men, whereas these effects were not found in women interacting with human partners. These findings support continued investigation into the possible efficacy of OT as a treatment for anxiety disorders.

Oxytocin and vasopressin effects on the neural response to social cooperation are modulated by sex in humans.

Recent research has examined the effects of oxytocin (OT) and vasopressin (AVP) on human social behavior and brain function. However, most participants have been male, while previous research in our lab demonstrated sexually differentiated effects of OT and AVP on the neural response to reciprocated cooperation. Here we extend our previous work by significantly increasing the number of participants to enable the use of more stringent statistical thresholds that permit more precise localization of OT and AVP effects in the brain. In a double-blind, placebo-controlled study, 153 men and 151 women were randomized to receive 24 IU intranasal OT, 20 IU intranasal AVP or placebo. Afterwards, they were imaged with fMRI while playing an iterated Prisoner's Dilemma Game with same-sex partners. Sex differences were observed for effects of OT on the neural response to reciprocated cooperation, such that OT increased the caduate/putamen response among males, whereas it decreased this response among females. Thus, 24 IU OT may increase the reward or salience of positive social interactions among men, while decreasing their reward or salience among women. Similar sex differences were also observed for AVP effects within bilateral insula and right supramarginal gyrus when a more liberal statistical threshold was employed. While our findings support previous suggestions that exogenous nonapeptides may be effective treatments for disorders such as depression and autism spectrum disorder, they caution against uniformly extending such treatments to men and women alike.

Sex differences in the neural and behavioral response to intranasal oxytocin and vasopressin during human social interaction.

Both oxytocin (OT) and vasopressin (AVP) are known to modulate social behavior, and dysfunction in both systems has been postulated as a potential cause of certain psychiatric disorders that involve social behavioral deficits. In particular, there is growing interest in intranasal OT as a potential treatment for certain psychiatric disorders, and preliminary pre-clinical and clinical studies suggest efficacy in alleviating some of the associated symptoms. However, the vast majority of research participants in these studies have been male, and there is evidence for sexually differentiated effects of nonapeptides in both humans and non-human animals. To date, no study has investigated the effect of intranasal OT on brain function in human males and females within the same paradigm. Previously, in a randomized, placebo-controlled, double-blind fMRI study, we reported effects of intranasal OT and AVP on behavior and brain activity of human males as they played an interactive social game known as the Prisoner's Dilemma Game. Here, we present findings from an identical study in human females, and compare these with our findings from males. Overall, we find that both behavioral and neural responses to intranasal OT and AVP are highly sexually differentiated. In women, AVP increased conciliatory behavior, and both OT and AVP caused women to treat computer partners more like humans. In men, AVP increased reciprocation of cooperation from both human and computer partners. However, no specific drug effects on behavior were shared between men and women. During cooperative interactions, both OT and AVP increased brain activity in men within areas rich in OT and AVP receptors and in areas playing a key role in reward, social bonding, arousal and memory (e.g., the striatum, basal forebrain, insula, amygdala and hippocampus), whereas OT and AVP either had no effect or in some cases actually decreased brain activity in these regions in women. OT treatment rendered neural responses of males more similar to responses of females in the placebo group and vice versa, raising the prospect of an inverted u-shaped dose response to central OT levels. These findings emphasize the need to fully characterize the effects of intranasal OT and AVP in both males and females and at multiple doses before widespread clinical application will be warranted.
