Discontinuing absorbent pants in children with bedwetting: a randomized controlled trial.

The objective of this study is to examine the effect of discontinuing wearing protective garments (absorbent pyjama pants - APP) in children with severe childhood nocturnal enuresis (NE). The study employs a multicenter, parallel, randomized controlled trial. Following a 4-week run-in period, participants were randomly allocated in a 2:1 group allocation to discontinue or continue using APP. The research was conducted across seven European pediatric incontinence centers. The study included treatment-naïve children aged 4-8 years with severe (7/7 wet nights per week) mono-symptomatic NE, who had used nighttime protection for at least 6 months prior to the study. The study consisted of a 4-week run-in period (± 7 days), where all children slept wearing APP (DryNites®). At week 4 (± 7 days), if meeting randomization criteria (7/7 wet nights during the last week of run-in), participants were randomized to continue to sleep in APP or to discontinue their use for a further 4 weeks, with the option of another 4 weeks in the extension period. The primary outcome was the difference between groups of wet nights during the last week of intervention. Quality of life (QoL) and sleep were secondary endpoints. In total, 105 children (43 girls and 62 boys, mean age 5.6 years [SD 1.13]) were randomized (no-pants group n = 70, pants group n = 35). Fifteen children (21%) in the no-pants group discontinued early due to stress related to the intervention. Children in the no-pants group experienced fewer wet nights compared to the pants group during the last week (difference 2.3 nights, 95% CI 1.54-3.08; p < 0.0001). In the no-pants group, 20% responded to the intervention, of whom 13% had a full response. Clinical improvement was detected within 2 weeks. Sleep and QoL were reported as negatively affected by APP discontinuation in the extension period but not in the core period.    Conclusion: A ~ 10% complete resolution rate was associated with discontinuing APP. While statistically significant, the clinical relevance is debatable, and the intervention should be tried only if the family is motivated. Response was detectable within 2 weeks. Discontinuing APP for 4-8 weeks was reported to negatively affect QoL and sleep quality. No severe side effects were seen.Trial registration: Clinicaltrials.gov Identifier: NCT04620356; date registered: September 23, 2020.

Preparation and characterization of a novel absorbent pad based on polyvinyl alcohol/gellan gum/citric acid with incorporated Perilla leaf oil nanoemulsion for chilled chicken packaging.

A novel absorbent pad based on polyvinyl alcohol (PVA)/gellan gum/citric acid (CA) composite with incorporated Perilla leaf oil (PO) nanoemulsion was prepared and characterized. The esterification between PVA and CA and strong hydrogen bonds were detected. The PVA improved the tensile strength and elongation at break by 110% and 73%, respectively, whereas PO concentration ≤ 1.5 % (w/v) had little effect on the material properties. The CA and PO nanoemulsion loaded in the pads showed good antioxidant activity, and the pads with PO concentration ≥ 1.5 % (w/v) had effective antimicrobial activity against Escherichia coli and Staphylococcus aureus. The results of chilled chicken storage experiments indicated that the pad with 1.5% (w/v) PO nanoemulsion extended the shelf life of chicken to at least 9 days, demonstrating that the developed absorbent pads are potential materials for chilled chicken storage packing.

Reusable and Disposable Incontinence Underpads: Environmental Footprints as a Route for Decision Making to Decarbonize Health Care.

BACKGROUND: Objectives of quality principles in the clinical setting present nursing with opportunities for quality patient care but at lower environmental footprint. This affects patients, hospital personnel, and community because choices reduce climate change and thus support an innovative nursing role. PURPOSE: This article aims to support nursing knowledge to include environment in decisions regarding patient care and reusable versus disposable incontinence underpads (IUPs). METHODS: A life cycle analysis was conducted, including soiling, reusable cycles before removal, supply chains, laundry use, and end-of-life environmental impact. RESULTS: The selection of reusable IUPs versus disposables reduced total natural resource energy consumption by 71%, greenhouse gas emissions by 61%, blue water consumption by 57%, and solid waste by 97%. CONCLUSIONS: The nursing community can use this information in its health care organizations regarding IUP to advocate for decisions to select reusable IUPs that benefit our environment (air, water, and land).

Changes in the quality and microbial compositions of ground beef packaged on food absorbent pads incorporated with levulinic acid and sodium dodecyl sulfate.

In this study, changes in the quality attributes (i.e., drip loss and color) and microbial compositions by both culture dependent and independent methods of ground beef packaged with food absorbent pads incorporating levulinic acid (LVA) plus sodium dodecyl sulfate (SDS) during a week of 4 °C storage were investigated. The pads containing LVA/SDS shown potent decontamination of tested microorganisms, including total aerobic counts (TAC), Enterobacteriaceae, Pseudomonas, and psychrotrophs, with a growth prevention of 6.0, >4.3, 8.6, and 8.5 log CFU/g in the pads at the end of the storage, respectively. Compared to the beef on the control pads, 1.0, 2.6, 4.3, and 2.9 log CFU/g lower counts of the abovementioned bacteria, respectively, in the beef on the LVA/SDS treated pads were recovered based on the culture dependent methods. The 16S rRNA amplicon high throughput sequencing analysis indicated that Pseudomonas, Acinetobacter and Photobacterium were the dominant genera in the beef at the end of the storage, and the pads containing LVA/SDS modified the microbial compositions which exhibited more microbial diversity than the control. The antimicrobial efficacy of the two compounds was nearly maintained during the whole storage time. Therefore, pads incorporating LVA plus SDS showed a potential to be an effective bactericide applied in antimicrobial active packaging.

Development of pH-responsive absorbent pad based on polyvinyl alcohol/agarose/anthocyanins for meat packaging and freshness indication.

Absorbent pads with antioxidant and pH-responsive color changing functions have been developed based on polyvinyl alcohol (PVA), agarose (AG), and purple sweet potato anthocyanins (PSPA), aiming for fresh keeping and freshness indication of meat. The effects of PSPA content on the structure, physical properties, and colorimetric response towards pH changing of pads were evaluated. The results showed that PSPA interacted with PVA and AG and influenced the crystallinity, thermal stability and micro-morphology of pads. The increase of the PSPA content from 3% to 12% improved the strength and DPPH radical scavenging activity of the pads, but reduced the swelling ratio. Significant color change of the pads was observed when pH increased from 3 to 10, and the pad containing 9% PSPA presented the most distinguishable color change with the change of pH. When applied as an absorbent pad for minced meat packaging, the pad indicated the real-time spoilage of the meat through obvious color change, and also extended the shelf life by at least 24 h. Therefore, the dual-functional pad shows great potential to be applied as a smart and active packaging for fresh meat, which would play an important role in ensuring food safety and improving food storage quality.

Aplicação da escala de avaliação do uso de fraldas em uma clínica médica de um hospital universitário / Application of the diaper use rating scale in a medical clinic of a university hospital / Aplicación de la escala de evaluación del uso de pañales en una clínica médica de un hospital universitario

Objectives:apply the evaluation scale for the use of diapers and absorbent products (AUFA Scale) in patients admitted to the medical clinic; identify and analyze the results of this application, the sociodemographic profile of patients in vogue as well as repercussions on the skin related to the use of sanitary pads and diapers. Method: observational, cross-sectional, descriptive and exploratory study, carried out in the medical clinic sector of the University Hospital Hospital Universitário Clementino Fraga Filho (HUCFF/UFRJ), from November 2019 to February 2020, with a convenience sample of 46 patients. There was application of a form to survey general data and, later, the application of the AUFA scale, which identified the following variables: skin conditions, skin aging, cognitive ability, motor skills and incontinence. Results: all 46 patients were using diapers, half women and the other half men, mostly elderly and without a diagnosis of incontinence. In view of the application and analysis of the AUFA scale, only 18 patients (39.14%) were indicated for diaper use. With the inappropriate use of diapers, 27 patients had skin lesions resulting from moisture, a situation that was justified by the absence of systematic care observation for the prevention and treatment of dermatitis associated with incontinence in the evaluated patients. Conclusion:the use of the AUFA scale is indicated to identify patients who need to wear diapers, delimiting care with their management and thus preventing complications and worsening of incontinence.

Objetivos:aplicar a escala de avaliação do uso fraldas e absorventes (AUFA) nos pacientes internados na clínica médica; identificar e analisar os resultados dessa aplicação, o perfil sociodemográfico dos pacientes em vogo bem como repercussões à pele relacionadas ao uso de absorventes e fraldas. Método: estudo observacional transversal, descritivo e exploratório, realizado no setor de clínica médica do Hospital Universitário Clementino Fraga Filho (HUCFF/UFRJ), no período de novembro de 2019 a fevereiro de 2020, com amostra por conveniência de 46 pacientes. Ocorreu aplicação de ficha para levantamento de dados gerais e, após, a AUFA, que identificou as seguintes variáveis: condições da pele, envelhecimento da pele, capacidade cognitiva, capacidade motora e incontinências. Resultados: todos os 46 pacientes encontravam-se em uso de fralda, sendo metade mulheres e a outra metade homens, em grande maioria composta de idosos e sem diagnóstico de incontinência. Diante da aplicação e análise da AUFA, apenas 18 pacientes (39,14%) tinham indicação para uso de fraldas. Com o uso inadequado da fralda, 27 pacientes apresentaram lesão de pele decorrente de umidade, situação que se justificou pela ausência da observação de cuidados sistematizados para prevenção e tratamento de dermatite associada à incontinência nos pacientes avaliados. Conclusão: indica-se o uso da escala AUFA para identificar os pacientes que necessitam usar fralda, delimitando cuidados com seu manejo e prevenindo, assim, complicações e agravamentos da incontinência.

Método: estudio observacional transversal, descriptivo y exploratorio, realizado en el sector de clínica médica del Hospital Universitario Clementino Fraga Filho (HUCFF/UFRJ), en el período de noviembre del 2019 a febrero del 2020, con muestra por conveniencia de 46 pacientes. Ocurrió la aplicación de ficha para el levantamiento de datos generales y, después, la AUFA, que identificó las siguientes variables: condiciones de la piel, envejecimiento de la piel, capacidad cognitiva, capacidad motora e incontinencias. Resultados: los 46 pacientes se encontraban en uso de pañal, siendo mitad mujeres y la otra mitad hombres, en gran mayoría compuesta por ancianos y sin diagnóstico de incontinencia. Ante la aplicación y análisis de la AUFA, solamente 18 pacientes (39,14%) tenían indicación para el uso de pañales. Con el uso inadecuado del pañal, 27 pacientes presentaron lesión de piel derivada de humedad, situación que se justificó por la ausencia de la observación de cuidados sistematizados para prevención y tratamiento de dermatitis asociada a la incontinencia en los pacientes evaluados. Conclusión: se indica el uso de la escala AUFA para identificar a los pacientes que necesitan usar pañal, delimitando cuidados con su manejo y previniendo, así, complicaciones y agravamientos de la incontinencia.

Integrating Sensor Technology in Disposable Body-Worn Absorbent Products: A Qualitative Study to Define User Profile, (Technical) Criteria, Conditions, and Potential Benefits.

PURPOSE: The purpose of this study was to define the user profile, (technical) criteria, conditions, and potential benefits of the integration of sensor technology in disposable body-worn incontinence materials. DESIGN: Qualitative study using a framework method. SUBJECT AND SETTING: The sample included residents with incontinence, nurses, and decision-makers in a selection of Flemish nursing homes (Belgium). METHODS: Semistructured interviews were performed between June and August 2020. The interviews with nurses included open-ended questions focusing on the user profile, (technical) criteria, conditions, and potential benefits of the integration of sensor technology in disposable body-worn incontinence materials. The interviews with decision-makers were supplemented with questions about purchase cost and other economic criteria (such as reimbursement). Interviews with residents included questions about wearing comfort. Interviews were tape-recorded and transcribed verbatim. Data were analyzed using a framework method. RESULTS: The user profile was defined as (1) residents with cognitive impairment and (2) residents who are bedridden or are severely limited in mobility. The following (technical) criteria emerged from the analyses: a small, thin, and oval/circular sensor, an adaptable or in front attachment of the sensor on the absorbent product, a real-time indication of the absorbent product's saturation, leakage detection, liquid stool detection, the automatic recording of incontinence-related data, a durable sensor easy to disinfect, and receiving notifications on a wearable device. Conditions included a stable connection between the wearable device and the sensor, accurate measurements, user-friendly system, comprehensible training, affordability, and data protection. Potential benefits included workload reduction, increased comfort for residents and staff, more person-centered care, increased quality of care, less skin damage and economic (eg, less costs due to less excessive absorbent product changes), and/or environmental (e.g. less waste) gains. CONCLUSION: Study findings identified the user profile, (technical) criteria, conditions, and potential benefits of the integration of sensor technology in disposable body-worn incontinence materials. Respondents reported problems with changing routines and skepticism about the sensor's accuracy. Based on findings from this study, we recommend involving representatives of all relevant stakeholders in the design of sensor technology to ensure users' needs and increase the use of sensor technology. Comprehensive education is recommended to inform nurses, residents, and their family members on the importance and benefits of the technology and to aid overcoming barriers to use (skepticism, resistance to new technologies, and changing care routines). Study findings also indicate that the sensor technology cannot replace the existing voiding programs; rather it should be an addition to routine continence care.

Comparación entre prostatectomía laparoscópica y abierta: análisis de la continencia urinaria poscirugía / Comparison between laparoscopic and open prostatectomy: Postoperative urinary continence analysis

INTRODUCCIÓN: Pocos son los estudios que comparan la prostatectomía radical abierta (PRA) con la prostatectomía radical laparoscópica (PRL) y sus resultados funcionales, como la continencia urinaria (CU), que es uno de los objetivos prioritarios tras el control oncológico. OBJETIVOS: Comparar la CU postoperatoria en los pacientes con adenocarcinoma de próstata localizado intervenidos mediante PRA frente a PRL. MATERIAL Y MÉTODOS: Comparación de dos cohortes (312 con PRA y 206 con PRL) entre los años 2007 y 2015. El estado de CU se recogió a los 3, 6, 12, 18 y 24meses. Para el manejo estadístico hemos agrupado la continencia en: a)CU, pacientes que no precisaron absorbentes, y b)incontinencia urinaria (IU), pacientes que precisaron absorbentes. Para el contraste de variables cualitativas se ha utilizado el test de la chi cuadrado para las variables cualitativas y ANOVA para las cuantitativas. Análisis multivariable mediante regresión logística para la variable dependiente IU. La significación estadística se consideró cuando existió una p < 0,05. RESULTADOS: En el 51,7% se realizó conservación neurovascular. A los 24meses de la cirugía, el 72,4% presentaban CU, de los cuales el 87,8% con PRA frente al 78,1% con PRL (p = 0,004). El 22,7% presentaron recidiva bioquímica (RB), siendo el 83% tratados con radioterapia de rescate (RTR). Los pacientes con RTR presentaron mayor porcentaje de IU frente a los que no la recibieron (p = 0,036). Se objetivó mayor porcentaje de estenosis de la anastomosis en PRA (p = 0,03). CONCLUSIONES: La PRL, la no preservación de los fascículos neurovasculares y la RTR se relacionaron directamente con la CU postoperatoria

INTRODUCTION: There are very few articles comparing open radical prostatectomy (ORP) vs. laparoscopic radical prostatectomy (LRP) and their functional results or urinary continence (UC), which is one of the most important objectives to pursue after oncological results. OBJECTIVES: To compare postoperative UC in patients with localized prostatic adenocarcinoma treated with OPR or LRP. MATERIAL AND METHODS: Comparison between two patient cohorts (312 for ORP and 206 for LRP) between 2007-2015. The UC was evaluated at 3, 6, 12, 18 and 24months. Continence was defined and classified as follows: a)UC, no need of pads, and b)urinary incontinence (UI), use of pads. To compare the qualitative variables, we employed the chi-squared test and ANOVA for quantitative variables. We performed a multivariate analysis using logistic regression with dependent qualitative variable UI. Statistical significance when P<.05. RESULTS: Nerve-sparing was performed in 51.7% cases. At 24months after surgery, 72.4% patients had UC, of which 87.7% were from the ORP group and 78.1% in the LRP group (P=.004). 22,7% of patients experienced biochemical recurrence (BR), with 83% treated with salvage radiotherapy (SRT), presenting greater UI percentage (P=.036). ORP patients showed a higher percentage of anastomosis stricture (P=.03). CONCLUSIONS: LRP, non-nerve sparing, and SRT were directly related to postoperative UI

The Effect of Absorbent Pad Design on Skin Wetness, Skin/Pad Microclimate, and Skin Barrier Function: A Quasi-experimental Open Cohort Study.

PURPOSE: The main aims of this study were to describe the effects of incontinence pad composition on skin wetness, the skin/pad microclimate, and skin barrier function. We also evaluated the potential utility of our methods for future clinical investigation of absorbent pad design. DESIGN: Single-blind, quasi-experimental, open cohort design. SUBJECTS AND SETTING: Twenty healthy older volunteers (mean age = 72.8 years, SD = 5.8 years; 8 male and 12 female) tested 2 absorbent pad types, with acquisition layers of different compositions (A and B) applied to different sites on the volar aspect of the forearms. One type A pad served as control (A dry) versus 3 pad samples wetted with 3 volumes of saline (A 15 mL, A 35 mL, and B 15 mL). The study was conducted within the clinical laboratory of a university nursing research group in the United Kingdom. METHODS: Skin barrier function was assessed by measuring transepidermal water loss (TEWL), stratum corneum (SC) hydration by corneometry, and skin surface pH using a standard skin pH electrode. Skin water loading (excess water penetration into the skin) was quantified by measuring TEWL and creating a desorption curve of the water vapor flux density. Calculating the area under the curve of the desorption curve to give skin surface water loss reflected excess water penetration into the skin. In a subgroup of the sample, the temperature and relative humidity (microclimate) at the interface between the skin and test pads were measured using a wafer-thin sensor placed between the skin and pad sample. Proinflammatory cytokine release from the SC was assessed using a noninvasive lipophilic film. The main outcome measures in this study were the differences in biophysical measurements of skin barrier function (TEWL, corneometer, and pH) before and after the application of the different pads. RESULTS: Mean ± SD baseline TEWL across all test sites was 10.4 ± 4.4 g/h/m. This increased to 10.6 ± 3.8 g/h/m at the control site, 15.3 ± 6.3 g/h/m for the A 15-mL pad, 15.3 ± 3.9 g/h/m for the A 35-mL pad, and 15.6 ± 3.2 g/h/m for the B 15-mL pad. The mean baseline skin surface pH was 5.9 ± 0.04; cutaneous pH increased to a mean of 6.1 ± 0.06 following all pad applications (P = .16). Mean SC hydration remained unchanged at the control site (A dry). In contrast, SC hydration increased following the application of all wetted pads. Target cytokines were detected in all samples we analyzed. The IL-1RA/IL-1α ratio increased following pad application, except for the wettest pad. CONCLUSION: Study findings suggest that absorbent pad design and composition, particularly the acquisition layer, affect performance and may influence skin health. Based on our experience with this study, we believe the methods we used provide a simple and objective means to evaluate product performance that could be used to guide the future development of products and applied to clinical settings.

Urinalysis Using a Diaper-Based Testing Device.

Urinary tract infections (UTI), one of the most common bacterial infections, annually affect 150 million people worldwide. Infants and the elderly are likely to have missed or delayed diagnosis of UTI due to difficulty clearly describing their symptoms. A rapid screening method for UTI is a critical and urgent need for these populations. The aim of our study is to develop a diaper-based testing device to assay urine biomarkers including pH, leukocyte, and nitrite level. This all-in-one device assists in urine collection and testing using a colorimetric approach to provide easily read visual results on the outside surface of a test strip-integrated diaper. In this study, we tested samples from 46 patients using testing strips and examined the results from 7 patients recruited to validate the strip-integrated diaper. In conclusion, this new diaper-based testing device is easy to use, rapid, and inexpensive, all of which imbue it with tremendous potential for development into a commercially viable UTI screening system.

Effect of insulation with bubble wrap and an absorbent pad on heat loss in anaesthetised cats.

Aims: To evaluate the efficacy of insulating the limbs and thorax of cats with a combination of bubble wrap and an absorbent, plastic-lined pad in reducing heat loss during ovariohysterectomy. Methods: A preliminary study was performed to compare heat loss of 1 L bags of Hartmann's solution heated to 38°C which were either wrapped in two layers of bubble wrap and an absorbent pad (n = 6) or were unwrapped (n = 6). Bags were allowed to cool in a temperature-controlled room and the temperature of the bags was measured every 10 minutes for 60 minutes. The clinical study, included 16 intact female cats undergoing ovariohysterectomy. The cats were premedicated with I/M morphine and either medetomidine or dexmedetomidine, and anaesthesia was induced with I/V propofol and maintained with isoflurane in 100% oxygen. Cats were randomly assigned to either the treatment group (n = 8) whose limbs and thorax wrapped with two layers of bubble wrap and an absorbent pad immediately after induction, or the control group (n = 8) which were unwrapped. Body temperature (measured with an oesophageal temperature probe), heart rate, respiratory rate, mean arterial pressure and partial pressure of end-tidal CO2 were recorded immediately after induction (T start), before surgery started (T surgery), and at the end of isoflurane administration (T end). The times from T end to extubation, from T end to when the cat could maintain sternal recumbency and from T end to when the cat was able to stand, were also recorded. Results: In the preliminary study of heat loss by fluid bags, the mean temperature at 60 minutes was higher in wrapped bags (35.4 (SD 0.2)°C) compared to unwrapped bags (33.0 (SD 0.3)°C; p < 0.01). For cats undergoing ovariohysterectomy, mean body temperature of wrapped cats was higher than that of unwrapped cats both at T surgery (36.0 (SE 0.3) vs. 34.5 (SE 0.3)°C; p = 0.001) and at T end (37.2 (SE 0.5) vs. 36.0 (SE 0.5)°C; p = 0.01). Wrapped cats regained the ability to stand more rapidly that unwrapped cats (26.4 (SE 5.8) vs. 47.0 (SE 5.8) minutes p = 0.01). Conclusions: Wrapping the limbs and thorax of cats undergoing ovariohysterectomy in a combination of bubble wrap and absorbent pads reduced heat loss, which in turn improved recovery time from general anaesthesia. Clinical relevance: This inexpensive and practical method may reduce perioperative hypothermia, in cats undergoing abdominal surgery.

Alarm interventions for nocturnal enuresis in children.

BACKGROUND: Enuresis (bedwetting) affects up to 20% of five-year-olds and can have considerable social, emotional and psychological effects. Treatments include alarms (activated by urination), behavioural interventions and drugs. OBJECTIVES: To assess the effects of enuresis alarms for treating enuresis in children. SEARCH METHODS: We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP, and handsearching of journals and conference proceedings (searched 25 June 2018), and reference lists of relevant articles. SELECTION CRITERIA: We included randomised or quasi-randomised trials of enuresis alarms or alarms combined with another intervention for treating nocturnal enuresis in children between 5 and 16 years old. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed risk of bias and extracted data. MAIN RESULTS: We included 74 trials (5983 children). At treatment completion, alarms may reduce the number of wet nights a week compared to control or no treatment (mean difference (MD) -2.68, 95% confidence interval (CI) -4.59 to -0.78; 4 trials, 127 children; low-quality evidence). Low-quality evidence suggests more children may achieve complete response (14 consecutive dry nights) with alarms compared to control or no treatment (RR 7.23, 95% CI 1.40 to 37.33; 18 trials, 827 children) and that more children may remain dry post-treatment (RR 9.67, 95% CI 4.74 to 19.76; 10 trials, 366 children; low-quality evidence). At treatment completion, we are uncertain whether there is any difference between alarms and placebo drugs in the number of wet nights a week (MD -0.96, 95% CI -2.32 to 0.41; 1 trial, 47 children; very low-quality evidence). Alarms may result in more children achieving complete response than with placebo drugs (RR 1.59, 95% CI 1.16 to 2.17; 2 trials, 181 children; low-quality evidence). No trials comparing alarms to placebo reported the number of children remaining dry post-treatment. Compared with control alarms, code-word alarms probably slightly increase the number of children achieving complete response at treatment completion (RR 1.11, 95% CI 0.97 to 1.27; 1 trial, 353 children; moderate-quality evidence) but there is probably little to no difference in the number of children remaining dry post-treatment (RR 0.91, 95% CI 0.79 to 1.05; moderate-quality evidence). Very low-quality evidence means we are uncertain if there are any differences in effectiveness between the other different types of alarm. At treatment completion, alarms may reduce the number of wet nights a week compared with behavioural interventions (waking, bladder training, dry-bed training, and star chart plus rewards) (MD -0.81, 95% CI -2.01 to 0.38; low-quality evidence) and may increase the number of children achieving complete response (RR 1.77, 95% CI 0.98 to 3.19; low-quality evidence) and may slightly increase the number of children remaining dry post-treatment (RR 1.39, 95% CI 0.81 to 2.41; low-quality evidence). The evidence relating to alarms compared with desmopressin in the number of wet nights a week (MD -0.64, 95% CI -1.77 to 0.49; 4 trials, 285 children) and the number of children achieving complete response at treatment completion (RR 1.12, 95% CI 0.93 to 1.36; 12 trials, 1168 children) is low-quality, spanning possible harms and possible benefits. Alarms probably slightly increase the number of children remaining dry post-treatment compared with desmopressin (RR 1.30, 95% CI 0.92 to 1.84; 5 trials, 565 children; moderate-quality evidence). At treatment completion, we are uncertain if there is any difference between alarms and tricyclics in the number of wet nights a week, the number of children achieving complete response or the number of children remaining dry post-treatment, because the quality of evidence is very low. Due to very low-quality evidence we are uncertain about any differences in effectiveness between alarms and cognitive behavioural therapy, psychotherapy, hypnotherapy and restricted diet. Alarm plus desmopressin may reduce the number of wet nights a week compared with desmopressin monotherapy (MD -0.88, 95% CI -0.38 to -1.38; 2 trials, 156 children; low-quality evidence). Alarm plus desmopressin may increase the number of children achieving complete response (RR 1.32, 95% CI 1.08 to 1.62; 5 trials, 359 children; low-quality evidence) and the number of children remaining dry post-treatment (RR 2.33, 95% CI 1.26 to 4.29; 2 trials, 161 children; low-quality evidence) compared with desmopressin alone. Alarm plus dry-bed training may increase the number of children achieving a complete response compared to dry-bed training alone (RR 3.79, 95% CI 1.85 to 7.77; 1 trial, 80 children; low-quality evidence). It is unclear if there is any difference in the number of children remaining dry post-treatment because of the wide confidence interval (RR 0.56, 95% CI 0.15 to 2.12; low-quality evidence). Due to very low-quality evidence, we are uncertain about any differences in effectiveness between alarm plus bladder training versus bladder training alone. Of the 74 included trials, 17 reported one or more adverse events, nine reported no adverse events and 48 did not mention adverse events. Adverse events attributed to alarms included failure to wake the child, ringing without urination, waking others, causing discomfort, frightening the child and being too difficult to use. Adverse events of comparator interventions included nose bleeds, headaches and abdominal pain. There is probably a slight increase in adverse events between code-word alarm and standard alarm (RR 1.34, 95% CI 0.75 to 2.38; moderate-quality evidence), although we are uncertain because of the wide confidence interval. Alarms probably reduce the number of children experiencing adverse events compared with desmopressin (RR 0.38, 95% CI 0.20 to 0.71; 5 trials, 565 children; moderate-quality evidence). Very low-quality evidence means we cannot be certain whether the adverse event rate for alarms is lower than for other treatments. AUTHORS' CONCLUSIONS: Alarm therapy may be more effective than no treatment in reducing enuresis in children. We are uncertain if alarm therapy is more effective than desmopressin but there is probably a lower risk of adverse events with alarms than with desmopressin. Despite the large number of trials included in this review, further adequately-powered trials with robust randomisation are still needed to determine the full effect of alarm therapy.

Visual estimation of postpartum blood loss during a simulation training: A prospective study.

OBJECTIVE: The objective of our study was to compare visually estimated blood loss (with collector bags and absorbent pads) during postpartum with the real volume during a simulation training. STUDY DESIGN: This study was conducted from May 23 to December 22, 2017 during training sessions on the theme of postpartum haemorrhage provided by the Elena perinatal network. 137 participants visually estimated the losses contained in 5 graduated collector bags (from 600 to 1800mL) and on 5 absorbent pads (from 200 to 1000mL). RESULTS: The averages of the visual estimated blood loss were significantly different from the real value, except for absorbent pads containing 400mL of losses. The low volumes are better estimated for either the absorbent pads or collector bags (p<0.001). 57% of the volumes were underestimated with collector bags, 33% of the estimates were accurate to ± 50 mL. With absorbent pads, 51% of the estimates were underestimated, compared to 22%, that were accurate. CONCLUSION: The simulation training allows to test the capacities of visual estimation of blood loss by health professionals in order to improve them and to improve the maternal care during postpartum haemorrhage.

A Laboratory Method for Determining Bacterially Formed Odorants and Reducing Odor in Absorbent Incontinence Products.

PURPOSE: The purpose of this study was to design a laboratory test method to mimic the formation of bacterially formed odorants during the use of absorbent urinary incontinence products. Three odor inhibitors with different modes of action were tested and evaluated. METHODS: Bacterially formed odorants in incontinence products were evaluated by adding a synthetic urine inoculated with a mixture of 4 bacterial strains to product samples cut from the incontinence products. The product samples were incubated in sealed flasks. The odorants that formed in the head space were sampled onto adsorbent tubes and analyzed by gas chromatography. The inhibitory effects of low pH, ethylenediaminetetraacetic acid (EDTA), and activated carbon were then measured. RESULTS: This technique enabled production of known odorants 3-methylbutanal, guaiacol, diacetyl, and dimethyl disulfide (DMDS) in concentrations of 50 to 600 ng/L in incontinence products. The method was further evaluated by testing 3 types of odor inhibitors; EDTA significantly reduced formation of all 4 odorants (P < .001). Lowering the pH from 6.0 to 4.9 decreased levels of 3-methylbutanal, DMDS, and guaiacol (P < .001); however, diacetyl levels increased (P < .001). Activated carbon significantly reduced the formation of diacetyl, DMDS, guaiacol, and 3-methylbutanal (P < .001). CONCLUSIONS: The technique we developed can be used to evaluate inhibitors with different modes of action to determine odor control in incontinence products. The odorants formed are produced by bacteria and have been identified as key contributors to the odor of used incontinence products. This work can be a step toward establishing a standard in the field of incontinence and odor control; creation of a standard will help the health care sector compare products to be purchased and benefit patients through the development of better products.

The impact of the absorbent products distribution system on family caregivers of older people with incontinence in Italy: perception of the support received.

BACKGROUND: Urinary incontinence is a chronic, age-related disorder, likely to increase in the future due to global population ageing. In Italy, as in most countries, older people with incontinence are often cared for by family caregivers, whose burden might be worsened by the perception of receiving an inadequate support, due to the lack of customized services. The aim of this study was to evaluate the impact of the absorbent products distribution method on family caregivers' perception of the support received. METHODS: The study compared the distribution of pads to homes and in pharmacy via a survey reaching 101 family caregivers of older people with incontinence living in two geographical areas of the Marche Region (Central Italy) with different distribution systems. The association between "Quality of perceived support" (the outcome variable) and two types of absorbent products delivery methods (i.e. pharmacy and home distribution) was analysed by means of a general linear model. RESULTS: Findings show that family caregivers receiving pads at home (HODs) perceived a higher support than those gaining them at the pharmacy (PHADs) (respectively 68.1% vs 35%). The association between perceived support level and distribution system remained even after correction for confounding factors. 70.2% of PHADs reported "Poor well-being", versus only 53.7% of HODs. The latter are more satisfied with the type of products distribution and thus less inclined to experiment different systems for the supply of products for the urinary continence (e.g. by voucher). The results are virtually reversed among PHADs and the difference is statistically significant (p <  0.001). CONCLUSIONS: When family caregivers feel supported by a more customized service delivery system, their perception of the care-related burden is mitigated. Thus, it is important to consider the needs of both family caregivers and cared for older people, and not only of the latter for designing a more suitable distribution of absorbent products. The best solution could be leaving end-users the freedom to choose how they want to get products (e.g. voucher or personal budget). This requires a reorganization of the current pads delivery systems adopted by the Marche and by other Italian Regional Health Systems.

Time of Onset to Changes in Skin Condition During Exposure to Synthetic Urine: A Prospective Study.

PURPOSE: The purpose of this study was to evaluate the impact of incontinence on epithelial-moisture barrier function and the subsequent risk for incontinence-associated dermatitis by exposing healthy volunteers to a premium incontinence pad wet with synthetic urine. DESIGN: Prospective, single-group study. PARTICIPANTS AND SETTING: Thirty women 65 years or older participated in the study. Participants had healthy skin of the buttocks, perineal, and perigenital areas and were not incontinent of urine or stool. The study was conducted at a contracted clinical research facility in Southeastern United States. METHODS: Four hundred milliliters of synthetic urine was distributed across the width of a premium incontinence pad with wicking technology containing a superabsorbent polymer core. Participants laid supine for a total of 4 hours, with the wet pad under the buttocks. Skin assessments were conducted at baseline prior to contact with the wet pad, at 15 minutes, 30 minutes, and 1, 2, and 4 hours after exposure to the synthetic urine. Outcome measures were skin moisture content, cutaneous pH, transepidermal water loss (TEWL), mean coefficient of friction values (static and dynamic), and tolerability evaluations (expert clinical grader-assessed erythema and participant-assessed discomfort). RESULTS: Mean moisture content of the skin increased from 46.19 ± 22.1 to 1845.28 ± 542.7 micro-Siemens (µS) after just 15 minutes of exposure and was significantly increased at all time points compared to baseline (P < .001). Cutaneous pH increased from 5.67 ± 0.5 to 6.25 ± 0.1 after 15 minutes; pH was higher at all time points compared to baseline (P < .001). Passive transfer of water through the stratum corneum (TEWL) showed an increase from 9.02 ± 2.2 g/m/h at baseline to 16.83 ± 5.2 g/m/h at 4 hours (P < .001). There was a significant increase from baseline to 4 hours in mean coefficient of static friction (0.32 ± 0.01 vs 0.47 ± 0.03; P < .00001) as well as mean coefficient of dynamic friction (0.29 ± 0.01 vs 0.42 ± 0.02; P < .00001). There was a significant increase in erythema and an increase in participant-assessed discomfort at all time points (P < .005). CONCLUSIONS: Our findings suggest that impairment of the skin's epithelial-moisture barrier function associated with inflammation and development of incontinence-associated dermatitis begins rapidly after an incontinence event, even with the use of a premium pad with wicking technology. Study findings also suggest that prompt attention to incontinence events is needed to prevent moisture-associated skin damage (incontinence-associated dermatitis) even when absorbent pads are used.

Uroflow stop test with electromyography: a novel index of urinary continence recovery after RARP.

PURPOSE: Urinary incontinence (UI) is one of the most bothersome surgical side effects after robot-assisted radical prostatectomy (RARP). Alteration of both smooth and striate urethral sphincter occurs after RARP. Since the contraction of perineal muscles is involved in the complex mechanism of urinary continence, the uroflow stop test (UST) seems to predict early continence recovery after RARP. The UST was added of perineal surface electromyography (EMG) evaluation to evaluate the latency time (LT) between muscular contraction and the complete stop of urine flow. Our aim was to present UST-EMG as a new tool in the investigation of UI, implying pelvic floor integrity, and to evaluate whether an early return (≤ 3 months) to preoperative LT could be associated with early recovery of UC (≤ 3 months). METHODS: After prospectively enrolling 137 patients who underwent RARP with a minimum follow-up of 6 months, we identified two groups: Group 1 (93 patients) with early (≤ 3 months) pre-surgical LT recovery and Group 2 (44 patients) with late > 3 months or not able to reach pre-surgical LT recovery. RESULTS: Between the two groups, there were significant differences in terms of different surgical technique (nerve-sparing versus non-nerve-sparing) and pads use at 3 and 6 months after RARP (p < 0.05). No differences were recorded neither in postoperative maximum flow-rate, nor in postoperative symptoms score. CONCLUSIONS: UST with EMG can be considered as a noninvasive, reproducible and easily performable tool. LT is applicable in the clinical evaluation to predict urinary continence recovery after RARP.

Sanitary pads and diapers contain higher phthalate contents than those in common commercial plastic products.

Sanitary pads and diapers are made of synthetic plastic materials that can potentially be released while being used. This study measured the amounts of volatile organic compounds (VOCs) (methylene chloride, toluene, and xylene) and phthalates (DBP, DEHP, DEP, and BBP) contained in sanitary pads and diapers. In sanitary pads, 5,900- and 130-fold differences of VOC and phthalate concentrations were seen among the brands. In the diapers, 3- and 63-fold differences of VOC and phthalate concentrations were detected among the brands. VOC concentrations from the sanitary pads and diapers were similar to that of the residential air. However, phthalate concentrations of sanitary pads and diapers were significantly higher than those found in common commercial plastic products. As sanitary pads and diapers are in direct contact with external genitalia for an extended period, there is a probability that a considerable amount of VOCs or phthalates could be absorbed into the reproductive system.
