Management of Symptom Flares and Patient-reported Flare Triggers in Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS)-Findings From One Site of the MAPP Research Network

OBJECTIVE

To document patient-reported interstitial cystitis/bladder pain syndrome (IC/BPS) flare management strategies and triggers.

MATERIALS AND METHODS

Twenty-four male and 29 female participants enrolled at the Washington University site of the MAPP Research Network completed a questionnaire on strategies they utilized to manage flares and factors they believed triggered their flares (eg, specific food items, physical activities, sexual activities, infections, and stress). Participants were also asked about the diurnal timing of their flares.

RESULTS

A total of 96.2% of participants reported having ever experienced a symptom flare. Participants treated or managed their flares using a wide variety of strategies, ranging from common strategies, such as drinking additional water or fluid (74.5%), to less common strategies, such as acupuncture/acupressure (5.9% of participants). Participants also reported a wide range of perceived flare triggers, including previously reported factors (citrus fruits, tomatoes, spicy food, alcoholic and caffeinated beverages, driving/sitting in forms of transportation, urinary tract infections, stress, and tight clothing), as well as some less common, previously undocumented factors (eg, certain foods, nongenitourinary infections, wearing high-heeled shoes/boots or perfume, hair dye, and toothpaste). In general, female participants and those with somatic sensory hypersensitivity reported greater numbers of therapies and triggers. Finally, flares were reported most commonly in the afternoon or evening.

CONCLUSION

IC/BPS participants reported diverse flare management strategies and numerous perceived triggers. These findings, together with those from the small body of literature to date, provide a wide array of candidates and hypotheses for future global and tailored flare management and prevention interventions.

Levels and patterns of self-reported and objectively-measured free-living physical activity among prostate cancer survivors: A prospective cohort study

Background

No prior study has measured or compared self‐reported and objectively measured physical activity trajectories in prostate cancer survivors before and after treatment.

Methods

Clinically localized prostate cancer patients treated with radical prostatectomy were recruited between 2011 and 2014. Of the 350 participants enrolled at the main site, 310 provided self‐reported physical activity at baseline before radical prostatectomy, and 5 weeks, 6 months, and 12 months after radical prostatectomy. A subset of participants (n = 81) provided objectively measured physical activity at all study time points by wearing an accelerometer for 7 days each. Changes in activity over time were compared using Friedman’s test. Agreement between self‐reported and objective measures was evaluated using Spearman’s rank correlation coefficient.

Results

Self‐reported moderate‐to‐vigorous physical activity was high at baseline (median, 32.1 min/day), followed by a decline at 5 weeks (median, 15.0 min/day) and a recovery at 6 and 12 months (median, 32.1‐47.1 min/day). In contrast, objectively measured moderate‐to‐vigorous physical activity was low at all 4 time points (median, 0.0‐5.2 min/day), with no overall change across study assessments (global P = .29). Self‐reported moderate‐to‐vigorous physical activity tended to be more closely related to objectively measured light‐intensity physical activity (ρ = 0.29‐0.42) than to objectively measured moderate‐to‐vigorous physical activity (ρ = 0.07‐0.27, P = .009‐.32).

Conclusions

In our population of prostate cancer survivors with critically low moderate‐to‐vigorous physical activity levels, self‐reported measures greatly overestimated moderate‐to‐vigorous physical activity and may have been more reflective of light‐intensity physical activity. Because cancer survivor guidelines are derived from self‐reported data, our findings may imply that intensities of physical activity below moderate, such as light intensity, still have health benefits.

In a population of 81 prostate cancer survivors with critically low moderate‐to‐vigorous physical activity levels, self‐reported measure greatly overestimates moderate‐to‐vigorous physical activity and may be more reflective of light‐intensity physical activity. Because prostate cancer guidelines are derived from self‐reported moderate‐to‐vigorous physical activity, the findings imply that lower intensities of physical activity, such as light‐intensity physical activity, may still have health benefits.

Association between Trichomonas vaginalis and prostate cancer mortality

We previously observed a positive association between seropositivity for the parasite Trichomonas vaginalis and risk of clinically significant prostate cancer at diagnosis. Here, we examined whether T. vaginalis seropositivity was associated with increased prostate cancer-specific or all-cause mortality among prostate cancer patients. We studied 736 men with prostate cancer from the Physicians' Health Study (PHS) and 749 men with prostate cancer from the Health Professionals Follow-Up Study (HPFS). We used Cox proportional hazards regression models to estimate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of the association between T. vaginalis serostatus and progression to death from prostate cancer and from all causes. In PHS, 423 men died of any cause during a median follow-up of 13.8 years from the date of cancer diagnosis, among whom 131 died of prostate cancer. In HPFS, there were 287 deaths, including 77 deaths from prostate cancer, during a median follow-up of 12.8 years. We found no association between T. vaginalis serostatus and either prostate cancer mortality or all-cause mortality in either the PHS or HPFS. While previous studies suggest a possible role for T. vaginalis in the development of clinically significant prostate cancer, our findings do not support the hypothesis that T. vaginalis serostatus is associated with mortality among prostate cancer patients.

Physical examination techniques for the assessment of pelvic floor myofascial pain: a systematic review

BACKGROUND

Myofascial pain is characterized by the presence of trigger points, tenderness to palpation, and local or referred pain, and commonly involves the pelvic floor muscles in men and women. Pelvic floor myofascial pain in the absence of local or referred pain has also been observed in patients with lower urinary tract symptoms, and we have found that many patients report an improvement in these symptoms after receiving myofascial-targeted pelvic floor physical therapy.

OBJECTIVE

We sought to systematically review the literature for examination techniques used to assess pelvic floor myofascial pain in women.

STUDY DESIGN

We performed a systematic literature search using strategies for the concepts of pelvic floor disorders, myofascial pain, and diagnosis in Ovid MEDLINE 1946-, Embase 1947-, Scopus 1960-, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, and Cochrane Database of Systematic Reviews. Articles were screened by 3 authors and included if they contained a description of a pelvic myofascial physical examination.

RESULTS

In all, 55 studies met our inclusion criteria. Overall, examination components varied significantly among the included studies and were frequently undefined. A consensus examination guideline was developed based on the available data and includes use of a single digit (62%, 34/55) to perform transvaginal palpation (75%, 41/55) of the levator ani (87%, 48/55) and obturator internus (45%, 25/55) muscles with a patient-reported scale to assess the level of pain to palpation (51%, 28/55).

CONCLUSION

Physical examination methods to evaluate pelvic musculature for presence of myofascial pain varied significantly and were often undefined. Given the known role of pelvic floor myofascial pain in chronic pelvic pain and link between pelvic floor myofascial pain and lower urinary tract symptoms, physicians should be trained to evaluate for pelvic floor myofascial pain as part of their physical examination in patients presenting with these symptoms. Therefore, the development and standardization of a reliable and reproducible examination is needed.

Occupation and lower urinary tract symptoms in women: A rapid review and meta-analysis from the PLUS research consortium

AIMS

Chronic, infrequent voiding may be a risk factor for lower urinary tract symptoms (LUTS) in women. To inform this hypothesis, we conducted a rapid literature review and meta-analysis of LUTS by occupation as an indirect measure of infrequent voiding behaviors.

METHODS

Two independent medical librarians searched Pubmed.gov studies (1990-2017) on adult women for occupations, industries, and workplace environment and LUTS outcomes: overactive bladder (OAB), urinary incontinence (UI), urinary tract infections (UTIs), and individual voiding and storage LUTS. Two authors reviewed full text articles meeting content criteria. Among studies with similar UI definitions, we estimated the prevalence of monthly UI using a random effects meta-analysis model.

RESULTS

Of 1078 unique citations identified, 113 underwent full article review and 33 met inclusion criteria. Twenty-six of these studies examined specific occupation groups, including nurses/midwives (n = 6 studies), healthcare workers/support staff (n = 6), military personnel (n = 3), teachers (n = 3), and other groups (n = 7), whereas eight compared findings across broad occupation groups. UI was reported in 30 studies (23% using validated measures), OAB in 6 (50% validated), and UTIs in 2 (non-validated). In pooled models, the degree of heterogeneity was too high (I²  = 96.9-99.2%) among the studies to perform valid prevalence estimates for LUTS.

CONCLUSIONS

Current literature limits the ability to evaluate LUTS by occupation types. Future studies should characterize voiding frequency and toilet access in a consistent manner by occupation and explore its relation to LUTS development.

Sustained influence of infections on prostate-specific antigen concentration: An analysis of changes over 10 years of follow-up

BACKGROUND

To extend our previous observation of a short-term rise in prostate-specific antigen (PSA) concentration, a marker of prostate inflammation and cell damage, during and immediately following sexually transmitted and systemic infections, we examined the longer-term influence of these infections, both individually and cumulatively, on PSA over a mean of 10 years of follow-up in young active duty U.S. servicemen.

METHODS

We measured PSA in serum specimens collected in 1995-7 (baseline) and 2004-6 (follow-up) from 265 men diagnosed with chlamydia (CT), 72 with gonorrhea (GC), 37 with non-chlamydial, non-gonococcal urethritis (NCNGU), 58 with infectious mononucleosis (IM), 91 with other systemic or non-genitourinary infections such as varicella; and 125-258 men with no infectious disease diagnoses in their medical record during follow-up (controls). We examined the influence of these infections on PSA change between baseline and follow-up.

RESULTS

The proportion of men with any increase in PSA (>0 ng/mL) over the 10-year average follow-up was significantly higher in men with histories of sexually transmitted infections (CT, GC, and NCNGU; 67.7% vs 60.8%, P = 0.043), systemic infections (66.7% vs 54.4%, P = 0.047), or any infections (all cases combined; 68.5% vs 54.4%, P = 0.003) in their military medical record compared to controls.

CONCLUSIONS

While PSA has been previously shown to rise during acute infection, these findings demonstrate that PSA remains elevated over a longer period. Additionally, the overall infection burden, rather than solely genitourinary-specific infection burden, contributed to these long-term changes, possibly implying a role for the cumulative burden of infections in prostate cancer risk.

Childhood diet and growth in boys in relation to timing of puberty and adult height: the Longitudinal Studies of Child Health and Development

PURPOSE

To begin to explore the possible roles of childhood diet and growth in prostate cancer (PCa) development, we investigated these exposures in relation to two known/suspected PCa risk factors, earlier pubertal timing and greater attained height, in the Longitudinal Studies of Child Health and Development.

METHODS

We used biannual/annual height, weight, and dietary history data to investigate childhood diet, body mass index (BMI), birth length, and childhood height in relation to PCa risk factors (age at peak height velocity (APHV), height at age 13, and adult height) for 64 Caucasian American boys.

RESULTS

In adjusted models, childhood fat and animal protein intake was positively associated with height at age 13 and adult height (P < 0.05). A childhood diet high in fat and animal protein and low in vegetable protein was also associated with earlier APHV (P < 0.05), whereas no associations were observed for childhood energy intake or BMI. Birth length and childhood height were positively associated with height at age 13 and adult height, and childhood height was inversely associated with APHV (P < 0.05).

CONCLUSION

Our findings suggest that both childhood diet and growth potential/growth contribute to earlier pubertal timing and taller attained height in males, supporting roles of these factors in PCa development.

Conducting a randomized trial in rural and urban safety-net health centers: Added value of community-based participatory research

BACKGROUND

Colorectal cancer (CRC) is the second most common cancer in the US. Despite evidence that screening reduces CRC incidence and mortality, screening rates are sub-optimal with disparities by race/ethnicity, income, and geography. Rural-urban differences in CRC screening are understudied even though approximately one-fifth of the US population lives in rural areas. This focus on urban populations limits the generalizability and dissemination potential of screening interventions.

METHODS

Using community-based participatory research (CBPR) principles, we designed a cluster-randomized trial, adaptable to a range of settings, including rural and urban health centers. We enrolled 483 participants across 11 health centers representing 2 separate networks. Both networks serve medically-underserved communities; however one is primarily rural and one primarily urban.

RESULTS

Our goal in this analysis is to describe baseline characteristics of participants and examine setting-level differences. CBPR was a critical for recruiting networks to the trial. Patient respondents were predominately female (61.3%), African-American (66.5%), and earned <$1200 per month (87.1%). The rural network sample was older; more likely to be female, white, disabled or retired, and have a higher income, but fewer years of education.

CONCLUSIONS

Variation in the samples partly reflects the CBPR process and partly reflects inherent differences in the communities. This confirmed the importance of using CBPR when planning for eventual dissemination, as it enhanced our ability to work within diverse settings. These baseline findings indicate that using a uniform approach to implementing a trial or intervention across diverse settings might not be effective or efficient.

Prevalence of Pubic Hair Grooming-Related Injuries and Identification of High-Risk Individuals in the United States

Importance

Pubic hair grooming is a common practice that can lead to injury and morbidity.

Objective

To identify demographic and behavioral risk factors associated with pubic hair grooming-related injuries to characterize individuals with high risk of injury and develop recommendations for safe grooming practices.

Design, Setting, and Participants

This cross-sectional study conducted a national survey of noninstitutionalized US adults (aged 18-65 years). The web-based survey was conducted through a probability-based web panel designed to be representative of the US population. Data were collected in January 2014 and analyzed from August 1, 2016, through February 1, 2017.

Main Outcomes and Measures

Grooming-related injury history (yes or no), high-frequency injuries (>5 lifetime injuries), and injury requiring medical attention.

Results

Among the 7570 participants who completed the survey (4198 men [55.5%] and 3372 women [44.5%]; mean (SD) age, 41.9 [18.9] years), 5674 of 7456 (76.1%) reported a history of grooming (66.5% of men and 85.3% of women [weighted percentages]). Grooming-related injury was reported by 1430 groomers (weighted prevalence, 25.6%), with more women sustaining an injury than men (868 [27.1%] vs 562 [23.7%]; P = .01). Laceration was the most common injury sustained (818 [61.2%]), followed by burn (307 [23.0%]) and rashes (163 [12.2%]). Common areas for grooming-related injury for men were the scrotum (378 [67.2%]), penis (196 [34.8%]), and pubis (162 [28.9%]); for women, the pubis (445 [51.3%]), inner thigh (340 [44.9%]), vagina (369 [42.5%]), and perineum (115 [13.2%]). After adjustment for age, duration of grooming, hairiness, instrument used, and grooming frequency, men who removed all their pubic hair 11 times or more during their lifespan had an increased risk for grooming injury (adjusted odds ratio [AOR], 1.97; 95% CI, 1.28-3.01; P = .002) and were prone to repeated high-frequency injuries (AOR, 3.89; 95% CI, 2.01-7.52; P < .001) compared with groomers who did not remove all their pubic hair. Women who removed all their pubic hair 11 times or more had increased odds of injury (AOR, 2.21; 95% CI, 1.53-3.19; P < .001) and high-frequency injuries (AOR, 2.98; 95% CI, 1.78-5.01; P < .001) compared with groomers who do not remove all their pubic hair. In women, waxing decreased the odds of high-frequency injuries (AOR, 0.11; 95% CI, 0.03-0.43; P = .001) compared with nonelectric blades. In total, 79 injuries among 5674 groomers (1.4%) required medical attention.

Conclusions and Relevance

Grooming frequency and degree of grooming (ie, removing all pubic hair) are independent risk factors for injury. The present data may help identify injury-prone groomers and lead to safer grooming practices.

Clinical and Psychosocial Predictors of Urological Chronic Pelvic Pain Symptom Change in 1 Year: A Prospective Study from the MAPP Research Network

PURPOSE

We examined baseline clinical and psychosocial characteristics that predict 12-month symptom change in men and women with urological chronic pelvic pain syndromes.

MATERIALS AND METHODS

A total of 221 female and 176 male patients with urological chronic pelvic pain syndromes were recruited from 6 academic medical centers in the United States and evaluated at baseline with a comprehensive battery of symptom, psychosocial and illness-impact measures. Based on biweekly symptom reports, a functional clustering procedure classified participant outcome as worse, stable or improved on pain and urinary symptom severity. Cumulative logistic modeling was used to examine individual predictors associated with symptom change as well as multiple predictor combinations and interactions.

RESULTS

About 60% of participants had stable symptoms with smaller numbers (13% to 22%) showing clear symptom worsening or improvement. For pain and urinary outcomes the extent of widespread pain, amount of nonurological symptoms and poorer overall health were predictive of worsening outcomes. Anxiety, depression and general mental health were not significant predictors of outcomes but pain catastrophizing and self-reported stress were associated with pain outcome. Prediction models did not differ between men and women and for the most part they were independent of symptom duration and age.

CONCLUSIONS

These results demonstrate for the first time in a large multisite prospective study that presence of widespread pain, nonurological symptoms and poorer general health are risk factors for poorer pain and urinary outcomes in men and women. The results point to the importance of broad based assessment for urological chronic pelvic pain syndromes and future studies of the mechanisms that underlie these findings.

The Prevention of Lower Urinary Tract Symptoms (PLUS) Research Consortium: A Transdisciplinary Approach Toward Promoting Bladder Health and Preventing Lower Urinary Tract Symptoms in Women Across the Life Course

Lower urinary tract symptoms (LUTS) are highly prevalent in women, and are expected to impose a growing burden to individuals and society as the population ages. The predominance of research related to LUTS has focused on underlying pathology, disease mechanisms, or the efficacy of treatments for women with LUTS. Although this research has been vital for helping to reduce or ameliorate LUTS conditions, it has done little to prevent the onset of LUTS. Health promotion and prevention require an expansion of scientific inquiry beyond the traditional paradigm of studying disease mechanisms and treatment to the creation of an evidence base to support recommendations for bladder health promotion and, in turn, prevention of LUTS. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) introduced the concept of prevention as an important priority for women's urologic research as a prelude to supporting the formation of the Prevention of Lower Urinary Tract Symptoms (PLUS) research consortium. In this article, we introduce the PLUS research consortium to the scientific community; share the innovative paradigms by which the consortium operates; and describe its unique research mission: to identify factors that promote bladder health across the life course and prevent the onset of LUTS in girls and women.

Caution with Use of the EPIC-50 Urinary Bother Scale: How Voiding Dysfunction Modifies its Performance

PURPOSE

We evaluated agreement between patient reported urinary function and bother, and sexual function and bother in patients treated with radical prostatectomy to help inform possible nonfunctional, modifiable mechanisms for patient bother.

MATERIALS AND METHODS

Patients were recruited from 2011 to 2014 at Washington University, and Brigham and Women's Hospital. Urinary and sexual outcomes were assessed by EPIC-50 (Expanded Prostate Cancer Index Composite-50) before, 5 weeks and 12 months after radical prostatectomy. Spearman rank correlation coefficients and agreement/disagreement categories were used to describe the relation between function and bother.

RESULTS

Despite moderate to good agreement between function and bother (urinary r = 0.51-0.69 and sexual r = 0.65-0.80) discordant groups were observed. In the urinary domain these groups were men disproportionately bothered by function at baseline (16.9%) and 12 months after radical prostatectomy (6.1%) and men less bothered by function 5 weeks (26.8%) and 12 months (9.9%) after radical prostatectomy. Discordant groups in the sexual domain were men less bothered by function at baseline (20.8%), and 5 weeks (21.1%) and 12 months (15.7%) after radical prostatectomy. Splitting the urinary bother scale into 2 subscales, including one for incontinence related bother to complement the urinary function scale which measures only incontinence, and one for voiding dysfunction related bother yielded considerably better agreement (urinary function and incontinence related bother r = 0.78-0.83). Factors contributing to the group less bothered by sexual function were unclear.

CONCLUSIONS

When using EPIC-50, investigators should consider splitting the urinary bother scale by the relation to incontinence to prevent distortions of function-bother and comparisons before vs after radical prostatectomy by coexisting voiding dysfunction.

Abstract 4259: The relation of childhood diet to the timing of puberty in boys: Results from the Longitudinal Studies of Child Health and Development

Background: Although accumulating evidence from different disciplines supports an early-life contribution to prostate cancer (PCa) risk, few studies have focused on this life stage. One major reason for this dearth of research is the decades-long span of time between early-life exposures and PCa onset, making traditional epidemiologic study designs challenging. To overcome this challenge, we took advantage of several well-supported or recently observed PCa risk factors - age at peak height velocity (APHV), height at age 13, and adult height - to shorten the time required to study early-life exposures and to improve exposure classification by using these risk factors as markers of future PCa risk. We focused our analysis on childhood diet because it influenced APHV in a similar study of girls, and because of its strongly suspected role in PCa development.

Methods: We analyzed data from the Longitudinal Studies of Child Health and Development, which followed 67 Caucasian boys from Boston from birth through adolescence in the 1930-40s. At each biannual (or annual) visit, study staff measured participants’ height and weight, and assessed their diet by dietary history interviews. We used these data to estimate age- and energy-adjusted nutrient intake, diet scores (combining information on fat and animal protein from ages 1-10 years into a Western diet score, and information on vegetable protein from ages 1-10 into a healthy diet score), age-specific height-z-scores, body mass index, peak height velocity (PHV), and APHV. We investigated crude associations between dietary and anthropometric measures by Pearson correlation coefficients, and multivariable-adjusted associations by linear regression.

Results: Childhood consumption of a Western diet (as measured by our fat-animal protein score) was positively associated with height at age 13 (beta coefficient (ß)=0.08, P&lt;0.001) and adult height (ß=0.05, P=0.013), and inversely associated with APHV (ß=-0.06, P=0.014). In contrast, childhood consumption of a healthy diet (as measured by our vegetable protein score) was inversely associated with height at age 13 (ß= -0.09, P=0.008). No notable associations were observed for diet and PHV. After controlling for height at ages 1-2 as a marker of genetic growth potential, only the association between Western diet and height at age 13 remained significant (ß=0.04, P&lt;0.001).

Conclusions: Our findings suggest that consumption of a Western diet during childhood (1-10 years of age) is associated with greater height at age 13, a possible marker of both earlier onset of puberty and greater height. As this measure was recently associated with later PCa risk/mortality in a large Danish cohort study, our findings may point towards an early dietary contribution to PCa risk. Future studies should explore this possible association further for its potential to inform primary PCa prevention strategies.

Exposure to maternal obesogenic diet worsens some but not all pre-cancer phenotypes in a murine genetic model of prostate cancer

Prostate cancer research has been predominantly focused on adult exposures and risk factors. However, because the prostate develops during gestation and early life, exposure to external factors, such as obesity, during development could affect the prostate cancer progression in adults. Our previous work demonstrated that exposure to a high fat/high sugar (HF/HS) diet during gestation and until weaning stimulated prostate hyperplasia and altered the Pten/Akt pathway in adult mice fed a normal diet after weaning. Here, we asked whether maternal exposure to HF/HS would worsen prostate phenotypes in mice lacking Pten, a widely accepted driver of prostate cancer. We found that, at six weeks of age, both Chow (control)—and HF/HS-exposed Pten knockout mice showed evidence of murine PIN that included ducts with central comedo necrosis but that the HF/HS exposure did not influence murine PIN progression. The Pten knockout mice exposed to HF/HS in utero had significantly more mitotic cells than Pten knockouts exposed to Chow diet. In the Pten null background, the maternal HF/HS diet enhanced proliferation but did not have an additive effect on Akt activation. We observed neuroendocrine differentiation in Pten knockout mice, a phenotype that had not been previously described in this model.

Insight into infection-mediated prostate damage: Contrasting patterns of C-reactive protein and prostate-specific antigen levels during infection

BACKGROUND

To investigate mechanisms underlying our previous observation of a large rise in serum prostate-specific antigen, a marker of prostate pathology, during both sexually transmitted and systemic infections, we measured serum high-sensitivity C-reactive protein (hsCRP), a marker of systemic inflammation, in our previous case-control study of young, male US military members and compared our findings to those for PSA.

METHODS

We measured hsCRP before and during infection for 299 chlamydia, 112 gonorrhea, and 59 non-chlamydial, non-gonococcal urethritis (NCNGU) cases; before and after infection for 55 infectious mononucleosis (IM) and 90 other systemic/non-genitourinary cases; and for 220-256 controls.

RESULTS

Only gonorrhea cases were significantly more likely to have a large hsCRP rise (≥1.40 mg/L or ≥239%) during infection than controls (P < 0.01). However, gonorrhea, IM, and other systemic/non-genitourinary cases were more likely to have a rise of any magnitude up to one year post-diagnosis than controls (p = 0.038-0.077).

CONCLUSIONS

These findings, which differ from those for PSA, suggest distinct mechanisms of elevation for hsCRP and PSA, and support both direct (eg, prostate infection) and indirect (eg, systemic inflammation-mediated prostate cell damage) mechanisms for PSA elevation. Future studies should explore our PSA findings further for their relevance to both prostate cancer screening and risk.

Characterization of Whole Body Pain in Urological Chronic Pelvic Pain Syndrome at Baseline: A MAPP Research Network Study

PURPOSE

We characterized the location and spatial distribution of whole body pain in patients with urological chronic pelvic pain syndrome using a body map. We also compared the severity of urinary symptoms, pelvic pain, nonpelvic pain and psychosocial health among patients with different pain patterns.

MATERIALS AND METHODS

A total of 233 women and 191 men with urological chronic pelvic pain syndrome enrolled in a multicenter, 1-year observational study completed a battery of baseline measures, including a body map describing the location of pain during the last week. Participants were categorized with pelvic pain if they reported pain in the abdomen and pelvis only. Participants who reported pain beyond the pelvis were further divided into 2 subgroups based on the number of broader body regions affected by pain, including an intermediate group with 1 or 2 additional regions outside the pelvis and a widespread pain group with 3 to 7 additional regions.

RESULTS

Of the 424 enrolled patients 25% reported pelvic pain only and 75% reported pain beyond the pelvis, of whom 38% reported widespread pain. Participants with a greater number of pain locations had greater nonpelvic pain severity (p <0.0001), sleep disturbance (p = 0.035), depression (p = 0.005), anxiety (p = 0.011), psychological stress (p = 0.005) and negative affect scores (p = 0.0004), and worse quality of life (p ≤0.021). No difference in pelvic pain and urinary symptom severity was observed according to increasing pain distribution.

CONCLUSIONS

Three-quarters of the men and women with urological chronic pelvic pain syndrome reported pain outside the pelvis. Widespread pain was associated with greater severity of nonpelvic pain symptoms, poorer psychosocial health and worse quality of life but not with worse pelvic pain or urinary symptoms.

Definitions of apical vaginal support loss: a systematic review

OBJECTIVE

We sought to identify and summarize definitions of apical support loss utilized for inclusion, success, and failure in surgical trials for treatment of apical vaginal prolapse.

BACKGROUND

Pelvic organ prolapse is a common condition affecting more than 3 million women in the US, and the prevalence is increasing. Prolapse may occur in the anterior compartment, posterior compartment or at the apex. Apical support is considered paramount to overall female pelvic organ support, yet apical support loss is often underrecognized and there are no guidelines for when an apical support procedure should be performed or incorporated into a procedure designed to address prolapse.

STUDY DESIGN

A systematic literature search was performed in 8 search engines: PubMed 1946-, Embase 1947-, Cochrane Database of Systematic Reviews, Cochrane Database of Abstracts of Review Effects, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, Proquest Dissertations and Theses, and FirstSearch Proceedings, using key words for apical pelvic organ prolapse and apical suspension procedures through April 2016. Searches were limited to human beings using human filters and articles published in English. Study authors (M.R.L.M., J.L.L.) independently reviewed publications for inclusion based on predefined variables. Articles were eligible for inclusion if they satisfied any of the following criteria: (1) apical support loss was an inclusion criterion in the original study, (2) apical support loss was a surgical indication, or (3) an apical support procedure was performed as part of the primary surgery.

RESULTS

A total of 4469 publications were identified. After review, 35 articles were included in the analysis. Prolapse-related inclusion criteria were: (1) apical prolapse (n = 20, 57.1%); (2) overall prolapse (n = 8, 22.8%); or (3) both (n = 6, 17.1%). Definitions of apical prolapse (relative to the hymen) included: (1) apical prolapse >-1 cm (n = 13, 50.0%); (2) apical prolapse >+1 cm (n = 7, 26.9%); (3) apical prolapse >50% of total vaginal length (-[total vaginal length/2]) (n = 4, 15.4%); and (4) cervix/apex >0 cm (n = 2, 7.7%). Sixteen of the 35 studies (45.7%) required the presence of symptoms for inclusion. A measurement of the apical compartment (relative to the hymen) was used as a measure of surgical success or failure in 17 (48.6%) studies. Definitions for surgical success included: (1) prolapse stage >2 in each compartment (n = 5, 29.4%); (2) prolapse >-[total vaginal length/2] (n = 2, 11.8%); (3) apical support >-[total vaginal length/3] (n = 1, 5.9%); (4) absence of prolapse beyond the hymen (n = 1, 5.9%); and (5) point C at ≥-5 cm (n = 2, 11.8%). Surgical failure was defined as: (1) apical prolapse ≥0 cm (n = 2, 11.8%); (2) apical prolapse ≥-1 cm (n = 2, 11.8%); (3) apical prolapse >-[total vaginal length/2] (n = 3, 17.6%); and (4) recurrent apical prolapse surgery (n = 1, 5.9%). Ten (28.6%) of the 35 studies also included symptomatic outcomes in the definition of success or failure.

CONCLUSION

Among randomized, controlled surgical trials designed to address apical vaginal support loss, definitions of clinically significant apical prolapse for study inclusion and surgical success or failure are either highly variable or absent. These findings provide limited evidence of consensus and little insight into current expert opinion.

Correlation between pubic hair grooming and STIs: results from a nationally representative probability sample

OBJECTIVE

STIs are the most common infections among adults. Concurrently, pubic hair grooming is prevalent. Small-scale studies have demonstrated a relationship between pubic hair grooming and STIs. We aim to examine this relationship in a large sample of men and women.

DESIGN

We conducted a probability survey of US residents aged 18-65 years. The survey ascertained self-reported pubic hair grooming practices, sexual behaviours and STI history. We defined extreme grooming as removal of all pubic hair more than 11 times per year and high-frequency grooming as daily/weekly trimming. Cutaneous STIs included herpes, human papillomavirus, syphilis and molluscum. Secretory STIs included gonorrhoea, chlamydia and HIV. We analysed lice separately.

RESULTS

Of 7580 respondents who completed the survey, 74% reported grooming their pubic hair, 66% of men and 84% of women. After adjusting for age and lifetime sexual partners, ever having groomed was positively associated with a history of self-reported STIs (OR 1.8; 95% CI 1.4 to 2.2), including cutaneous STIs (OR 2.6; CI 1.8 to 3.7), secretory STIs (OR 1.7; CI 1.3 to 2.2) and lice (OR 1.9; CI 1.3 to 2.9). These positive associations were stronger for extreme groomers (OR 4.4; CI 2.9 to 6.8) and high-frequency groomers (OR 3.5; CI 2.3 to 5.4) with cutaneous STIs, and for non-extreme groomers (OR 2.0; CI 1.3 to 3.0) and low-frequency groomers (OR 2.0; CI 1.3 to 3.1) with lice.

CONCLUSIONS

Among a representative sample of US residents, pubic hair grooming was positively related to self-reported STI history. Further research is warranted to gain insight into STI risk-reduction strategies.
