Collection and preservation of urinary proteins, using a fluff pulp diaper.

Change is the most fundamental property of a biomarker. In contrast to the blood, which is under homeostatic controls, urine reflects changes in the body earlier and is more sensitive, thus making it a better biomarker source. Moreover, drawing blood from infants and toddlers is difficult and not tolerated well. For patients limited by language, communicating their chief complaint is difficult. Thus, monitoring biomarkers in urine can provide valuable clues for the diagnosis of diseases, especially pediatric diseases. Collecting urine from young children and some adult patients is more challenging than collecting it from healthy adults. Here, we propose a method that uses a fluff pulp diaper to collect urine. Urinary proteins are then eluted and adsorbed onto a piece of nitrocellulose membrane, which can be dried and stored in a vacuum bag. SDS-PAGE and LC-MS/MS analysis indicated that this method is reproducible, and similar proteins were identified as those obtained by an acetone precipitation method. With this simple and economical method, it is possible to collect and preserve urine samples from infants, toddlers, and patients with special needs, even for large-scale biomarker studies.

Disposable Versus Reusable Absorbent Underpads for Prevention of Hospital-Acquired Incontinence-Associated Dermatitis and Pressure Injuries.

PURPOSE: The primary purpose of our study was to determine if there is a difference in the occurrence of hospital-acquired pressure injuries (HAPIs) and incontinence-associated dermatitis (IAD) in incontinent adults using a disposable versus reusable absorptive underpads. We also compared hospital length of stay in the 2 groups. DESIGN: Randomized controlled trial using cluster randomization based on inpatient care unit. SUBJECTS AND SETTING: Four hundred sixty-two patients admitted to 4 medical-surgical study units participated in the study; 252 used reusable underpads (control group) and 210 subjects used disposable underpads (intervention group). The study setting was a 711-bed acute care hospital located in Brooklyn, New York. METHODS: Two units were randomly allocated to use disposable incontinence pads, and the remaining 2 units used standard, reusable incontinence pads. Data for PI and IAD occurrences were collected weekly by specially trained RNs (skin care champions) on the assigned units. A 2-level hierarchical linear model was used to analyze the effects of the intervention on primary and secondary outcomes separately from any effects of the unit of randomization. RESULTS: HAPIs were significantly lower in the disposable underpads group: 5% versus 12% (P = .02). Rates of hospital IAD were not significantly different between the groups (P = .22). Analysis of a secondary outcome, hospital length of stay, was also lower in patients who used disposable underpads (6 days vs 8 days; P = .02). CONCLUSIONS: Findings suggest that use of disposable incontinence pads reduces HAPI but not IAD occurrences. The effect of disposable, absorbent incontinence pads should be considered when initiating a hospital-wide skin and PI prevention and treatment plan.

Is single incision midurethral sling effective in patients with low maximal urethral closure pressure?

OBJECTIVE: To ascertain whether low preoperational maximal urethral closure pressure (MUCP) affects the outcomes of single incision sling (SIS) procedures and changes MUCP values postsurgery. MATERIAL AND METHODS: There were 112 (MUCP ≥ 40 cmH2O, n = 88; MUCP < 40 cmH2O, n = 24) consecutive women with urodynamic stress incontinence who had undergone SIS (MiniArc) procedures included in this study. The threshold of 40 cmH2O was used since it has been shown to be a significant risk factor for failed incontinence surgery. Clinical outcomes were assessed by the cough stress test, the 1-hour pad test, the Incontinence Impact Questionnaire-Short Form, the Urogenital Distress Inventory six-item questionnaire, the Sexual Questionnaire-SF, and postoperative changes in the urodynamic parameters. A comparison of the 1-year follow-up data is presented. RESULTS: Three months postsurgery, a significant decrease was observed in the 1-hour pad test, from 20.6 g preoperatively to 0.73 g postoperatively (p < 0.001). The objective cure rate was 82.1% without any significant differences between the two groups (p = 0.202). At 3 months and 1 year after surgery, significantly decreasing Urogenital Distress Inventory six-item questionnaire and Incontinence Impact Questionnaire-Short Form, and increasing Sexual Questionnaire-SF scores were observed in both groups, without any significant differences between the two groups. No statistically significant difference in the subjective cured rate was noted between the two groups at the 3-month and 18.4 month follow-ups. The postoperative MUCP was significantly decreased in the MUCP ≥ 40 group (p < 0.05) while significantly increased in the MUCP < 40 group (p = 0.006). CONCLUSIONS: These results suggest that SIS is a safe and highly effective treatment for urodynamic stress incontinence even in women with low MUCP at a mean follow-up of 18.4 months. Evaluation of the outcomes with more subjects after a longer follow-up period is necessary.

Analysis of the usage of continence pads and help-seeking behavior of women with stress urinary incontinence in Poland.

BACKGROUND: Urinary incontinence (UI) in women is a chronic disorder which has a negative impact on health-related quality of life. Only 45 % of the affected individuals report the problem with continence to their doctor. The aim of the study was to assess the duration of stress urinary incontinence (SUI), time from disease onset to the first medical consultation and in-depth diagnosis, as well as the need for using continence pads in various grades of SUI. METHODS: We conducted a cross-sectional study in women who presented at the urogynecologic ambulatory center and reported urinary incontinence. A total of 420 subjects were interviewed and underwent urogynecologic and urodynamic examinations. A group of 147 patients with urodynamic SUI was enrolled in the study. RESULTS: All women were graded according to the Stamey severity score: grade 1 - 56 (38.1 %), grade 2 - 68 (46.3 %), and grade 3 - 23 (15.6 %). Mean time elapsed between disease onset and presentation at the urogynecologic ambulatory center was 17.4 ± 11.8 years (grades 1, 2 and 3 for 11.6 ± 11.8, 14.9 ± 10.8, and 22.2 ± 12.1 years, respectively; p = 0.0002). Patients with SUI started perceiving their condition as a problem 4.7 ± 5.4 years before referral to urodynamics; 58.3 % of the SUI patients reported their problems with continence to a physician. Average time between the onset of UI symptoms and seeking medical help was 13.28 ± 12.3 years. Mean duration of using continence pads during the day was 4.2, 5.4 and 10.2 years in grades 1, 2 and 3, respectively (p = 0.0002). The number of patients using continence pads in and outside the home, as compared to outside only, was: grade 1 - 44.6 % vs. 28.6 %, grade 2 - 77.6 % vs. 13.4 %, and grade 3 - 86.4 % vs. 9.1 % (p = 0.004). Mean use of continence pads at night was 3.3, 6.1, and 9.1 years in grades 1, 2 and 3, respectively. The differences were not statistically significant. Protective continence products were used at night by 26.7 % of the SUI patients: 16.1 %, 25 % and 59.1 % in grades 1, 2 and 3, respectively (p = 0.004). CONCLUSIONS: Women with SUI delay seeking medical help for over a decade. The severity of SUI is associated with duration and increased use of continence pads.

Impact of onabotulinumtoxinA on quality of life and practical aspects of daily living: A pooled analysis of two randomized controlled trials.

OBJECTIVE: To evaluate the impact of onabotulinumtoxinA on individual domains of the quality of life questionnaires in a pooled analysis of two phase 3 trials in overactive bladder patients with urinary incontinence who were inadequately managed by ≥1 anticholinergic. METHODS: Patients received intradetrusor injections of onabotulinumtoxinA 100U (n = 557) or placebo (n = 548). The proportions of patients with a positive response (condition "greatly improved" or "improved") on the Treatment Benefit Scale, and changes in Incontinence Quality of Life scores and King's Health Questionnaire domain scores were analyzed in the overall population and subgroups with clean intermittent catheterization use and urinary tract infection status during the first 12 weeks of treatment. Responses to individual King's Health Questionnaire items were also assessed. RESULTS: Significantly greater proportions of onabotulinumtoxinA-treated patients achieved positive Treatment Benefit Scale response versus placebo (61.8% vs. 28.0%; P < 0.001). OnabotulinumtoxinA showed significantly greater improvements versus placebo in Incontinence Quality of Life total (22.5 vs. 6.6), Incontinence Quality of Life subscale scores and all domains of the King's Health Questionnaire. Notably, a similar trend was observed regardless of clean intermittent catheterization/urinary tract infection status. Additionally, onabotulinumtoxinA resulted in significantly greater improvements than the placebo in practical aspects of patients daily lives, including pad use, need to change undergarments, sleep, relationship with partner and work life/daily activities. CONCLUSION: In overactive bladder patients with urinary incontinence, onabotulinu-mtoxinA 100U demonstrated significant improvements across the individual domains of the quality of life questionnaires, regardless of clean intermittent catheterization or urinary tract infection status, and provided a positive impact on practical aspects of patients' daily lives.

Pad weighing for reduction of indwelling urinary use and catheter-associated urinary tract infection: a quality improvement project.

Catheter-associated urinary tract infections pose a significant risk to hospitalized patients. Measuring accurate urinary output is a common reason for indwelling catheterizations in acutely ill patients. The risk of catheter-associated infections may be eliminated while maintaining ability to measure urinary output of incontinent patients through the use of a highly absorbent pad and weighing postincontinence. The dry pad weight is subtracted from the wet pad weight and the resulting difference (expressed in grams) equals the volume of urine leaked into the pad in milliliters. We found that using this system of improved measurement of urine output when compared to documenting the number of incontinent episodes while allowing removal of indwelling urethral catheters as soon as possible.

Randomized clinical trial comparing TVT Secur system and trans vaginal obturator tape for the surgical management of stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: This prospective randomized study aimed to compare the safety and efficacy of the TVT-Secur (TVT-S) with the trans vaginal obturator tape (TVT-O) for the treatment of stress urinary incontinence. METHODS: We set out to enroll 136 patients in our study. 106 patients with stress urinary incontinence were randomized to either the TVT-S (n = 56) or TVT-O (n = 50) procedure. Patients were evaluated postoperatively at 2 months and 1 year. Our primary outcome was objective cure measured by the cough test. Secondary outcomes of subjective symptoms, questionnaires, pain scores, complications, and urodynamic studies were also included. Statistical analysis was by Chi-squared, Kruskal-Wallis, Wilcoxon, and Fisher's exact tests as appropriate. P values of <0.05 were considered significant. RESULTS: Objective cure rates were better for TVT-O compared with TVT-S at 1 year (86 % and 63 % respectively, p = 0.01). Subjective cure rates were 88 % for TVT-O and 63 % for TVT-S. Quality of life scores through questionnaires improved in both groups and were not statistically different. Initial post-operative groin pain was more prevalent in the TVT-O group; however, this resolved quickly with time. CONCLUSION: TVT-O was superior to TVT-S in the objective cure of stress urinary incontinence at 1-year follow-up.

Urinary continence after radical prostatectomy: predictive factors of recovery after 1 year of surgery.

OBJECTIVES: To evaluate the clinical prognosis of incontinence and to determine the predictors for further recovery of urinary continence in patients not achieving urinary continence within 1 year after radical prostatectomy. METHODS: A total of 708 patients were evaluated regarding urinary continence status at 1 year after surgery from a prospectively maintained radical prostatectomy database. Of these, 73 (10.3%) did not recover urinary continence within 1 year after surgery. For these patients, incontinence status and the number of pads for urinary control were assessed serially. RESULTS: In 708 patients, factors associated with the recovery of urinary continence within 1 year after radical prostatectomy were membranous urethral length, prostatic apex shape and patient age. Among 73 patients with urinary incontinence, 41 (56.2%) achieved urinary continence with a mean time of 15.4 months subsequent to the first year after radical prostatectomy (baseline). A younger age at surgery (P = 0.027) and one pad being required (vs ≥2 pads) at baseline (P = 0.046) were identified as independent factors for achievement of urinary continence within a further 2 years. Only the number of pads was a significant factor for further recovery of urinary continence in the longer follow up (hazard ratio 0.36, P = 0.029). CONCLUSION: Compared with factors related to the prostate or membranous urethra, patient age and severity of incontinence at 1 year after radical prostatectomy are more strongly related to the recovery of urinary continence later than 1 year after surgery. These findings might help to decide whether a definite treatment is required for persistent incontinence beyond 1 year after radical prostatectomy.

An investigator blinded cross-over study to characterize the cutaneous effects and suitability of modern sanitary pads for menstrual protection for women residing in the USA.

BACKGROUND: The cutaneous and sensory effects of the practical usage of sanitary pads have been studied globally. However, clinical studies in the United States were conducted only quite a long time ago, and the results of these studies were not published. METHODS: Fifty-four women residing in the United States were asked to use commercially available sanitary pads with a nonwoven unique surface sheet and pads with a perforated film. This was a cross-over study design conducted over the course of two menstrual periods. A board certified dermatologist evaluated the levels of erythema and fissuring, burning, stinging and itching sensations based on clinical observations and interviews. Measurement of pH and swabs for bacteria counting of vulvar skin were also performed. Data from the first clinical evaluation conducted prior to the first menstrual cycle were used as the baseline. At the end of the study, the subjects were asked to complete self-assessment questionnaires about product suitability. RESULTS: Forty-two women (age: 18-50, mean: 37.5) completed the study. No signs of irritation or meaningful differences from the baseline were found in the clinical observations or in the interviews by the dermatologist for either product. No significant difference from baseline was found in the vulvar skin surface pH or in the number of total bacteria for either product. The results of the suitability indicated that the majority of subjects were highly satisfied with both types, but they especially preferred the sanitary pad with a nonwoven unique surface top sheet. CONCLUSION: These results revalidate the results of a previous clinical study in the United States and are consistent with recent reports of worldwide clinical trials of high performance sanitary pads.

The effects of a multi-intervention incontinence care program on clinical, economic, and environmental outcomes.

PURPOSE: The aim of the study was to assess the effects of a multi-intervention program consisting of use of new absorbent products, a structured skin care regimen, and nursing advice on clinical (incontinence-associated dermatitis [IAD]), economic, and environmental outcomes. SUBJECTS AND SETTING: The study setting was a nursing home in northern Italy. Sixty-three patients with urinary incontinence participated, including 46 women and 17 men. Their average was 84.0 ± 9.1 years (mean ± SD). Thirty-five participants were entirely dependent on others for activities of daily living, such as bathing or dressing. DESIGN: Single-group, pre-/postintervention study. METHODS: The multi-intervention program was implemented in 3 phases: (1) initial assessment of incontinence care (phase 0, baseline measurement), (2) introduction of new absorbent products for incontinence and a structured skin care regimen (phase 1), and (3) introduction of advice provided by continence nurses (phase 2). RESULTS: All 63 subjects were found to have IAD at baseline.When compared to baseline measurement, the relative risk of IAD following implementation of phase 1 (new absorbent products and structured skin care regimen) was 0.24 (95% confidence interval [CI], 0.16-0.35). Adding advice from continence nurses during this final phase (2) of the study further diminished the relative risk of IAD to 0.15 (95% CI, 0.04-0.59). In addition,the relative risk of IAD was 0.03 (95% CI 0.01-0.12) when the complete intervention (new absorbent products, structured skin care regimen, and continence nurse advice) was compared to baseline measurement. Baseline evaluation revealed that incontinent residents used an average of 5.19 absorbent products,at a mean cost of € 1.79 per day. Following introduction of the multi-intervention program, the mean number of absorbent products consumed per day was 2.02 per incontinent patient, at a mean cost of € 0.97 per day. In addition to these clinical and economic outcomes, implementation of the multi-intervention program reduced the daily production of waste generated by the nursing home from 33 to 11 kg/d. CONCLUSIONS: Results of this study suggest that a multi-intervention program, including introduction of new absorbent products, a structured skin hygiene program, and advice from continence nurses, reduce the relative risk of IAD, absorbent product use, and generation of waste materials.

Cutaneous and sensory effects of two types of sanitary pads with different surfaces in the Shanghai, Chinese population.

BACKGROUND: Regional differences in practices, ethnicity, and climate may influence the skin compatibility of sanitary pads. Although several clinical trials have been performed in North America, Mexico, Western Europe, Eastern Europe, and Africa, there is no clinical study reported for Asia. OBJECTIVE: The purpose of this study was to examine the skin compatibility of two types of modern sanitary pads in Chinese women along with a dermatological assessment and their satisfaction and preference. MATERIALS AND METHODS: The self-feeling and safety of a new sanitary pad with a non-woven top specially-shaped surface sheet was tested and compared with a conventional sanitary pad with a perforated film top sheet. The subjects studied were 22 Chinese women (age: 20-50 years) with a history of mild and occasional sanitary pad dermatitis residing in Shanghai. One subject wished to discontinue the trial for personal reasons, thus 21 subjects completed the trial. These subjects were randomly assigned to two types of sanitary pads, and used one type during their next menstrual period, and another type during their following menstrual period. After each menstrual period, a dermatologist examined the objective and subjective skin symptoms and determined a score. The subjects were asked to rate their level of satisfaction with respect to overall usability, softness, stickiness, dryness, and absorbency, and to choose which pad they had preferred. RESULTS: No adverse effect was observed for either type of pad. Edema, erythema, burning, and stinging were not obvious symptoms for either type of pad. For itching, 30-65% of the subjects scored slight or mild for both types of pads. A comprehensive evaluation showed that several symptoms were observed on both type of pads at slight and mild levels, but minimal and insignificant differences were found between them. The majority of subjects were highly satisfied with both types, but preferred the new sanitary pad with a non-woven specially-shaped surface top sheet for its softness and absorbency. CONCLUSION: Our results indicate that both types of sanitary pads were tolerated well by Chinese women, thereby providing an important extension of earlier studies.

The usefulness of sebum check film for measuring the secretion of sebum.

Patients with atopic dermatitis (AD) often present with dry skin, and the reduced secretion of sebum may be responsible for the impaired skin barrier function. A sebum check film enables the patient to self-evaluate the skin sebum content. This study compared the sebum check film with a sebumeter. The skin sebum content of the forehead was measured using a sebum check film and a sebumeter. The findings of the sebum content of healthy controls showed that the sebum dot fields on the sebum check film were significantly correlated with the sebum content measured using the sebumeter (r = 0.774, p < 0.001). In addition, the sebum fields on the sebum check film of AD patients (n = 26) were significantly less than those on the sebum check film of the controls (n = 30; p < 0.05). Furthermore, the analysis of the sebum fields on the sebum check film of the AD patients was significantly correlated with their sebum content findings that were obtained using a sebumeter (r = 0.592, p < 0.01). These findings indicate that the sebum check film is easy to use for measuring the sebum secretion and is suitable for self-checking the sebum contents by AD patients for daily skin care.

Influence of usage practices, ethnicity and climate on the skin compatibility of sanitary pads.

Modern disposable sanitary pads are becoming available worldwide. Regional differences in usage practices, ethnicity, and climate may influence their skin compatibility. Pad usage practices depend on culture, economics, and menstrual physiology. Daily usage is higher in Japan and but lower in Nigeria compared to North America or Western Europe. Evidence for ethnic differences in skin irritant susceptibility is not compelling. Dark skin may be less susceptible to certain irritants than fair skin; the Japanese may experience a higher degree of sensory irritation than Caucasians. Ambient conditions such as high temperature and humidity increase the skin temperature and skin surface moisture under sanitary pads by small but measurable amounts, causing no discernible skin irritation; vapor-permeable pad backings reduce these effects. Cold dry conditions, which can irritate exposed skin, may not affect vulvar skin to the same degree due to its elevated hydration and occlusion. To address the practical significance of these variables, results of prospective clinical trials of sanitary pads performed by industry and academic scientists in North America (Indiana), Mexico, Western Europe (Munich, Athens, Goteborg, Sweden), Eastern Europe (Kiev) and Africa (Abuja, Nigeria) were reviewed. Despite the diverse range of conditions, no significant adverse skin effects were observed with modern pads compared to traditional pad designs. Study participants generally preferred modern pads for performance and comfort.

A multi-centre evaluation of absorbent products for men with light urinary incontinence.

AIMS: This study compared the performance of the four main designs of absorbents for men with light incontinence: pouches (shields), leafs (guards), washable pant with integral pad (pantegral), and small disposable pad. MATERIALS AND METHODS: We did a multiple crossover trial. Men with light urinary incontinence were recruited. All pouches and leafs available in the UK were identified for inclusion. A single pantegral and small pad were selected based on previous evaluations for design comparison. Products were tested in random order for up to 1 week. Performance criteria (e.g., leakage and comfort) were rated using a validated product performance questionnaire. Wet product weights and amount of leakage were recorded in pad leakage diaries. "Overall opinion" for design performance was used as the primary outcome indicator. RESULTS: Seventy-four men tested six leafs, six pouches, one pantegral, and one small pad. Leakage data was taken from 3,386 wet pads. The pouches generally performed poorly with few significant differences between products. The leafs were more variable with large and significant differences in ratings. Overall the leaf, pantegral, and small pad designs performed significantly better than the pouch (P

Discreet products for children and teenagers with continence problems.

The National Service Framework for Children, Young People and Maternity Services (Department of Health, 2004a) estimates that 'at least 500,000 children suffer from nocturnal enuresis, and a significant number with daytime wetting and faecal incontinence'. The NSF also acknowledges that 'incontinence is distressing for children and young people; it can lead to bullying at school and cause emotional and behavioural problems'.
