Non-invasive antidromic neurostimulation:A simple effective method for improving bladder storage

Patients with intractably diminished bladder storage function are encountered frequently by neurourologists, occasionally requiring reconstructive surgery for appropriate resolution. Although sacral neuromodulation is a recognized effective therapeutic modality, present techniques are technically demanding, invasive, and expensive. This study investigated the effect of non-invasive third sacral nerve (S3) stimulation on bladder activity during filling cystometry. One hundred forty-six patients underwent standard urodynamic filling cystometry that was then immediately repeated. Patients in the study group (n = 74) received antidromic transcutaneous sacral neurostimulation during the second fill and the control group (n = 72) underwent a second fill without neurostimulation. A statistically significant increase in bladder storage capacity without a corresponding rise in detrusor pressure was observed in the neurostimulated patients. This improvement in functional capacity is an encouraging finding that further supports the use of this non-invasive treatment modality in clinical practice. Neurourol. Urodynam. 20:73-84. 2001.

Transcutaneous sacral neurostimulation for irritative voiding dysfunction

with refractory irritative voiding dysfunction. Following an initial response, patients may successfully apply this treatment themselves to ensure long-term relief. Objective: Patients with irritative voiding dysfunction are often unresponsive to standard clinical treatment. We evaluated the response of such individuals to transcutaneous electrical stimulation of the third sacral nerve. Methods: 32 patients with refractory irritative voiding dysfunction (31 female and 1 male; mean age 47 years) were recruited to the study. Ambulatory transcutaneous electrical neurostimulation was applied bilaterally to the third sacral dermatomes for 1 week. Symptoms of frequency, nocturia, urgency, and bladder pain were scored by each patient throughout and up to 6 months following treatment. Results: The mean daytime frequency was reduced from 11.3 to 7.96 (p = 0.01). Nocturia episodes were reduced from a mean of 2.6 to 1.8 (p = 0.01). Urgency and bladder pain mean symptom scores were reduced from 5.97 to 4.89 and from 1.48 to 0.64, respectively. After stopping therapy, symptoms returned to pretreatment levels within 2 weeks in 40% of the patients and within 6 months in 100%, Three patients who continued with neurostimulation remained satisfied with this treatment modality at 6 months. Conclusions: Transcutaneous third sacral nerve stimulation may be an effective and noninvasive ambulatory technique for the treatment of patients with refractory irritative voiding dysfunction. Following an initial response, patients may successfully apply this treatment themselves to ensure long-term relief.

THE ARTIFICIAL URINARY SPHINCTER - A NEW SOLUTION FOR INCONTINENT PATIENTS

Treatment of urinary incontinence with the artificial urinary sphincter has been available in centres such as London and Liverpool for a number of years. This service is now available in the department of urology of the Belfast City Hospital. Twelve patients have had successful implantation of an artificial urinary sphincter for urinary incontinence, and ten are now fully continent. One patient with Wegener's granulomatosis developed active disease in his urethra which has precluded activation of the device. One patient has had the device removed because of erosion into the urethra.

Patient-reported 'ever had' and 'current' long term physical symptoms following prostate cancer treatments

OBJECTIVE: To document prostate cancer patient reported 'ever experienced' and 'current' prevalence of disease specific physical symptoms stratified by primary treatment received.
PATIENTS: 3,348 prostate cancer survivors 2-15 years post diagnosis.
METHODS: Cross-sectional, postal survey of 6,559 survivors diagnosed 2-15 years ago with primary, invasive PCa (ICD10-C61) identified via national, population based cancer registries in Northern Ireland and Republic of Ireland. Questions included symptoms at diagnosis, primary treatments and physical symptoms (impotence/urinary incontinence/bowel problems/breast changes/loss of libido/hot flashes/fatigue) experienced 'ever' and at questionnaire completion ("current"). Symptom proportions were weighted by age, country and time since diagnosis. Bonferroni corrections were applied for multiple comparisons.
RESULTS: Adjusted response rate 54%; 75% reported at least one 'current' physical symptom ('ever':90%), with 29% reporting at least three. Prevalence varied by treatment; overall 57% reported current impotence; this was highest following radical prostatectomy (RP)76% followed by external beam radiotherapy with concurrent hormone therapy (HT); 64%. Urinary incontinence (overall 'current' 16%) was highest following RP ('current'28%, 'ever'70%). While 42% of brachytherapy patients reported no 'current' symptoms; 43% reported 'current' impotence and 8% 'current' incontinence. 'Current' hot flashes (41%), breast changes (18%) and fatigue (28%) were reported more often by patients on HT.
CONCLUSION: Symptoms following prostate cancer are common, often multiple, persist long-term and vary by treatment. They represent a significant health burden. An estimated 1.6% of men over 45 is a prostate cancer survivor currently experiencing an adverse physical symptom. Recognition and treatment of physical symptoms should be prioritised in patient follow-up. This information should facilitate men and clinicians when deciding about treatment as differences in survival between radical treatments is minimal.

Bladder interstitial cells:an updated review of current knowledge

The field of bladder research has been energized by the study of novel interstitial cells (IC) over the last decade. Several subgroups of IC are located within the bladder wall and make structural interactions with nerves and smooth muscle, indicating integration with intercellular communication and key physiological functions. Significant progress has been made in the study of bladder ICs' cellular markers, ion channels and receptor expression, electrical and calcium signalling, yet their specific functions in normal bladder filling and emptying remain elusive. There is increasing evidence that the distribution of IC is altered in bladder pathophysiologies suggesting that changes in IC may be linked with the development of bladder dysfunction. This article summarizes the current state of the art of our knowledge of IC in normal bladder and reviews the literature on IC in dysfunctional bladder.

Can group exercise programs improve health outcomes in pregnant women? A systematic review

Current scientific evidence supports the recommendation to initiate or continue the practice of physical exercise in healthy pregnant women. Group exercise programs have positive effects in improving health and well-being, as well as social support. In order to understand the scientific evidence in this field, and the outcomes in maternal health, it has generated wide interest in exploring the studies carried out with more relevant group exercise programs. The aim of this systematic review was to evaluate the available evidence on the effectiveness of group exercise programs in improving women’s and newborns health outcomes during pregnancy. Three databases were used to conduct literature searches and strict inclusion and exclusion criteria were employed. Seventeen studies were selected for analysis. All studies were randomized control trials conducted with pregnant women that evaluated the effect of group exercise programs on the health outcomes of mother and newborn. Most studies followed a supervised structured exercise program including a main aerobic part, resistance training, pelvic floor training and stretching and relaxation sections. The significant effects of the programs are related with improved maternal perception of health status, lower maternal weight gain, improved levels of maternal glucose tolerance, improved aerobic fitness and muscular strength, lower frequency of urinary incontinence, improved sick leave due to lumbopelvic pain, fewer cesarean and instrumental deliveries, higher newborn Apgar score and faster postpartum recovery. Exercise and health professionals should advise pregnant women that aerobic group exercise during pregnancy improves a wide range of health outcomes for the women and newborn

Avaliação do perfil de cuidado de enfermagem geriátrico em hospitais de Portugal

A transição demográfica e epidemiológica da população portuguesa tem e terá um enorme impacto na utilização dos recursos de saúde. Atualmente, as pessoas idosas representam um dos grupos etários com taxas de internamento hospitalar mais significativos. Contudo, os dados sobre a hospitalização destas pessoas têm demonstrado resultados de saúde negativos, nomeadamente, o declínio funcional e cognitivo e o risco elevado de eventos adversos. Os/as enfermeiros/as têm um papel crucial na mudança desta realidade. Deste modo, a associação entre o contexto no qual decorre o cuidado de enfermagem geriátrica e os resultados deste cuidado relativos a/os utentes, enfermeiros/as e organizações têm sido proficuamente documentados. Algumas estratégias para promover a qualidade do cuidado geriátrico e a segurança das pessoas idosas hospitalizadas consistem em avaliar e (re)criar o ambiente de trabalho geriátrico dos/as enfermeiros/as (AGTE) e capacitar e treinar estes/as profissionais no cuidado à pessoa idosa. Embora, internacionalmente, os dados demonstrem a associação entre as características de hospitais e/ou enfermeiros/as e o AGTE, não existem estudos em Portugal nesta área, bem como sobre o conhecimento e as atitudes destes profissionais no contexto hospitalar. Por conseguinte, este estudo teve como objetivos: 1) traduzir, adaptar culturalmente e validar as escalas que compõem o questionário Geriatric Institucional Assessment Proflie (GIAP) para a população portuguesa; 2) analisar o AGTE (fatores intrínsecos e extrínsecos) que apoiam ou dificultam a adoção das melhores práticas geriátricas em hospitais portugueses; 3) analisar as atitudes e conhecimento de enfermeiros/as acerca de quatro síndromes geriátricas (úlceras de pressão, distúrbio do sono, contenção física e incontinência), destacando as boas práticas e os problemas encontrados nos hospitais portugueses; 4) analisar a relação entre as variáveis demográficas, profissionais e as características dos hospitais e as escalas que compõem o GIAP – versão portuguesa; 5) conhecer as perceções de enfermeiros/as acerca do cuidado às pessoas idosas hospitalizadas e dos obstáculos enfrentados para desenvolver um cuidado de boa qualidade; e 6) analisar a relação entre a perceção de enfermeiros/as sobre o AGTE e o conhecimento e atitudes geriátricas destes profissionais em função da região e unidade de internamento. Este estudo foi desenvolvido com base num método quantitativo do tipo exploratório-descritivo, transversal, prospetivo e correlacional. A amostra foi constituída por 1.068 enfermeiros/as de cinco hospitais da região norte e centro do país. A recolha de dados foi desenvolvida através de autopreenchimento do GIAP – versão portuguesa. De entre os principais resultados destacam-se: 1) a obtenção de um instrumento válido e fiável para avaliar o AGTE e conhecimentos e atitudes geriátricas; 2) a perceção de enfermeiros/as sobre o cuidado às pessoas idosas como sendo predominantemente negativa; 3) a perceção de enfermeiros/as sobre o apoio insuficiente dos líderes hospitalares para promover um AGTE favorável; 4) o cuidado a pessoas idosas com comportamentos inadequados e o uso de recursos geriátricos como os principais fatores que influenciam a eficácia e a qualidade do cuidado geriátrico; 5) a lacuna de conhecimento e atitudes negativas de enfermeiros/as acerca das quatro síndromes geriátricas; 6) a conceptualização de um modelo sobre a associação das características de enfermeiros/as, dos hospitais do estudo e das perceções destes/as profissionais sobre o cuidado geriátrico com o AGTE e o conhecimento e atitudes geriátricos; 7) a falta de apoio familiar, a descontinuidade e a escassez de tempo para o cuidado como principais obstáculos no cuidado à pessoa idosa hospitalizada; e 8) o perfil de cuidado geriátrico nos hospitais da região norte e centro de Portugal como tendencialmente homogéneo. Os resultados deste estudo sustentam a necessidade de um maior investimento dos decisores políticos, administradores hospitalares e docentes de Enfermagem na capacitação dos/as enfermeiros/as para o cuidado geriátrico e na promoção de um AGTE mais favorável. Também oferece recomendações significativas nos domínios da decisão política, da gestão institucional e da prática profissional que devem ser alvo de uma discussão alargada entre os vários agentes com responsabilidade nestes domínios. Espera-se que este estudo possa contribuir para a promoção de um contexto favorável ao desenvolvimento de um cuidado de enfermagem geriátrica de boa qualidade às pessoas hospitalizadas.

Protocolo de Treino dos Músculos do Pavimento Pélvico em Mulheres com Incontinência Urinária de Esforço: Revisão Sistemática

Introdução: Os exercícios de fortalecimento dos músculos do pavimento pélvico (EFMPP) são considerados a primeira intervenção no tratamento da incontinência urinária de esforço (IUE), porém os EFMPP são distintos, não existindo evidência sobre os parâmetros de treino. Objetivo: Identificar o protocolo e/ ou os parâmetros de treino dos músculos do pavimento pélvico (MPP) mais eficaz no tratamento da IUE feminina. Método: A pesquisa bibliográfica foi realizada entre janeiro de 1992 a março de 2014 nas bases de dados PubMed, Cochrane Library, PEDro, web of Science e LILACS. Os artigos incluídos eram de língua inglesa, estudos experimentais, no qual comparavam EFMPP com o tratamento placebo, usual ou sem tratamento, com idade compreendida entre os 18 e os 65 anos e diagnóstico de IUE. Os critérios de exclusão abrangeram o diagnóstico de IUE desencadeada por fatores externos ao trato urinário inferior, grávidas, puérperas, prolapso ≥ 2 e outros tipos de IU. A avaliação da qualidade metodológica for realizada através da escala PEDro. Resultados: Sete artigos de elevada qualidade metodológica foram incluídos na presente revisão. A amostra foi constituída por 331 mulheres, com idade média de 44,4 anos, duração média das perdas urinárias de 64 meses e a gravidade da IUE variou entre ligeira a severa. Os programas de EFMPP eram distintos em relação aos parâmetros de treino dos MPP, sendo que alguns estudos incluíram o treino abdominal, supervisão e técnicas adjuvantes. A taxa de curada da quantidade de perda urinária variou entre 28,6 a 80%, enquanto a força dos MPP variou de 15,6% a 161,7%. Conclusão: Na presente revisão sistemática, os EFMPP combinados com palpação digital, biofeedback e cones vaginais parecem ser mais eficazes na redução da quantidade de perda urinária, comparado com os EFMPP isolados ou sem tratamento. Esta revisão permitiu igualmente identificar as 12 semanas de duração da intervenção, 10 repetições por série e diferentes posições, sendo os parâmetros de treino mais consistentes na redução dos sintomas.

Pelvic floor dysfunction 6 years post-anal sphincter tear at the time of vaginal delivery.

INTRODUCTION AND HYPOTHESIS: This study aims to estimate fecal, urinary incontinence, and sexual function 6 years after an obstetrical anal sphincter tear. METHODS: Among 13,213 women who had a vaginal delivery of a cephalic singleton at term, 196 women sustained an anal sphincter tear. They were matched to 588 controls. Validated questionnaires grading fecal and urinary incontinence, and sexual dysfunction were completed by the participants. RESULTS: Severe fecal incontinence was more frequently reported by women who had sustained an anal sphincter tear compared to the controls. Women with an anal sphincter tear had no increased risk of urinary incontinence, but reported significantly more pain, difficulty with vaginal lubrication, and difficulty achieving orgasm compared to the controls. A fetal occiput posterior position during childbirth was an independent risk factor for both severe urinary incontinence and severe sexual dysfunction. CONCLUSIONS: Fecal incontinence is strongly associated with an anal sphincter tear. A fetal occiput posterior position represents a risk factor for urinary incontinence and sexual dysfunction.

Artificial muscle: the human chimera is the future.

Severe heart failure and cerebral stroke are broadly associated with the impairment of muscular function that conventional treatments struggle to restore. New technologies enable the construction of "smart" materials that could be of great help in treating diseases where the main problem is muscle weakness. These materials "behave" similarly to biological systems, because the material directly converts energy, for example electrical energy into movement. The extension and contraction occur silently like in natural muscles. The real challenge is to transfer this amazing technology into devices that restore or replace the mechanical function of failing muscle. Cardiac assist devices based on artificial muscle technology could envelope a weak heart and temporarily improve its systolic function, or, if placed on top of the atrium, restore the atrial kick in chronic atrial fibrillation. Artificial sphincters could be used to treat urinary incontinence after prostatectomy or faecal incontinence associated with stomas. Artificial muscles can restore the ability of patients with facial paralysis due to stroke or nerve injury to blink. Smart materials could be used to construct an artificial oesophagus including peristaltic movement and lower oesophageal sphincter function to replace the diseased oesophagus thereby avoiding the need for laparotomy to mobilise stomach or intestine. In conclusion, in the near future, smart devices will integrate with the human body to fill functional gaps due to organ failure, and so create a human chimera.

L’utilisation de la réadaptation par la réalité virtuelle pour traiter l’incontinence urinaire mixte de la femme âgée : une étude de faisabilité

But : Cette étude a comme objectif principal d’évaluer la faisabilité d’utiliser une combinaison de renforcement des muscles du plancher pelvien (MPP) et de réadaptation par la réalité virtuelle (RRV) (programme d’entraînement MPP/RRV) pour traiter l’incontinence urinaire mixte (IUM) de la femme âgée. La faisabilité est évaluée par le taux de participation et d’achèvement du programme d’entraînement MPP/RRV et du programme d’exercices à domicile. Les objectifs secondaires de cette étude sont 1) d’évaluer l’effet du programme d’entraînement MPP/RRV sur la sévérité des symptômes urinaires, sur les dimensions de la qualité de vie, sur la fonction musculaire des MPP et sur les fonctions cognitives, plus précisément le processus exécutif de coordination de deux tâches, 2) d’évaluer, suite à l’intervention, la satisfaction des participantes. Le volet qualitatif a, quant à lui, pour objectif d’identifier les facteurs ayant influencé la participation au programme d’entraînement MPP/RRV ainsi que les avantages et les inconvénients associés à l’ajout de la RRV au traitement conventionnel de renforcement des MPP. Méthode : Les participantes ont effectué deux évaluations pré-traitement (pré-1 et pré-2), ont assisté à 12 classes hebdomadaires d’entraînement MPP/RRV et ont effectué une évaluation post-traitement. Elles ont aussi complété un programme d’exercices des MPP à domicile. Finalement, suite à la dernière classe, elles ont participé à un groupe de discussion. Les évaluations pré-1 et pré-2 ont été effectuées à deux semaines d’intervalle et étaient nécessaires pour s’assurer de la stabilité des mesures en l’absence d’une intervention. Résultats : 24 femmes ont participé à l’étude. Les taux de participation aux classes d’exercices hebdomadaires et au programme d’exercices à domicile étaient de 91 % et de 92 % respectivement. Le taux d’achèvement au programme d’entraînement MPP/RRV était de 96 %. Le programme d’entraînement MPP/RRV s’est avéré efficace dans l’amélioration des symptômes urinaires, de la qualité de vie ainsi que de la capacité à coordonner deux tâches simultanées chez les femmes âgées avec de l’IUM; il tend également à améliorer la fonction musculaire du plancher pelvien de ces femmes. L’appréciation de la composante RRV, par les participantes, était de 9.8/10 et ces dernières l’ont identifiée comme un facilitateur à leur participation hebdomadaire au traitement. Conclusion : Ce projet de maîtrise a permis de démontrer qu’une combinaison de renforcement des MPP et de RRV est une approche de traitement acceptable pour les femmes âgées souffrant d’IUM puisqu’elles sont capables de suivre les exigences de ce programme d’entraînement.

Procrastination et faiblesse de la volonté : Agentivité, temporalité et défaillances de la rationalité pratique

Étant pourtant un phénomène extrêmement répandu, la procrastination a très peu fait l’objet d’études philosophiques. Inversement, la faiblesse de la volonté et les différents phénomènes qu’on lui rattache sont encore aujourd’hui étudiés en profondeur comme des cas paradigmatiques de défaillance de la rationalité pratique. Or, la procrastination présente un cas de défaillance de la rationalité pratique particulier dans notre rapport avec le temps, rapport qui est très souvent laissé de côté dans l’étude de la faiblesse de la volonté. Après avoir présenté dans le premier chapitre les phénomènes majeurs associés à la faiblesse de la volonté et les problématiques qu’ils soulèvent, dans le deuxième chapitre, nous examinerons leurs liens avec la procrastination. Nous verrons comment la procrastination, avec son emphase sur le caractère temporel de notre agentivité, permet de mieux saisir et d'expliquer les problématiques soulevées par la faiblesse de la volonté en les insérant dans un cadre explicatif plus large.
