Prevalência de incontinência urinária e fatores associados em idosos institucionalizados

Urinary incontinence (UI) is a geriatric syndrome that is especially prevalent in institutionalized individuals, and that causes economic and social impacts derived from treatment costs and overload of caregiver. UI also entails physical consequences to the health of the elderly, such as urinary tract infections or pressure ulcers, among other health problems. However, the existing national research on this condition is still scarce and comprises serious methodological biases. Therefore, the objective of this study is to determine the prevalence of urinary incontinence and associated factors in institutionalized elderly. A cross-sectional study is presented herein, conducted between October and December, 2013 and carried out in 10 nursing homes in the city of Natal (Northeast Brazil). UI was verified through the program Minimum Data Set version 3.0, which was also used to assess fecal incontinence, urinary devices and UI control programs. Data collection included sociodemographic information, UI characterization, as well as variables related to the institution itself and to health conditions (comorbidities, medication, pelvic floor surgery, Barthel Index for functional capacity and Pfeiffer test for cognitive status). Bivariate analysis was performed using the Chi-Square Test (or Fisher‟s Exact Test) and the Linear Chi-Square Test, calculating the prevalence ratio with 95% confidence interval. Variables with p value under 0.20 were included in the multivariate analysis, which was performed using the Stepwise Forward logistic regression. The inclusion of variables in the final model depended on the likelihood ratio test, absence of multicollinearity and on the Hosmer-Lemeshow test. A statistical significance level of 0.05 was considered. Six (1.8%) hospitalized elderly, one individual in palliative care (0.3%) and one (0.3%) individual under the age of 60 were excluded from the study. The final sample consisted of 321 elderly, mostly females, with a mean age of 81.5 years. The prevalence of UI was 59.43% and the final model revealed statistically a significant association between UI and white race, physical inactivity, stroke, mobility constraints and cognitive decline. The most frequent UI type was functional UI due to physical or cognitive disability, and incontinence control measures were applied only to a minority of residents (approximately 8%). It is concluded that UI is a health issue that affects more than half of the institutionalized elderly, and is associated with white race, physical inactivity, stroke and other geriatric syndromes such as immobility and cognitive disability. Most of these associated factors are modifiable and therefore the findings of this study highlight the importance of UI prevention and treatment in nursing homes, which include general measures, such as physical and psychosocial activities, and specific measures, such as prompted voiding

Prevalência e fatores associados ao risco e a desnutrição em idosos institucionalizados

One of the most important problems in the elderly is a nutritional deficiency. Several physiological changes and the use of multiple drugs interfere with appetite, food intake and absorption of nutrients, which can lead to the risk and malnutrition in the elderly, especially among institutionalized. The present study aimed to evaluate the prevalence of malnutrition and risk for malnutrition and its associated factors in institutionalized elderly. The same can be characterized by the type individual, observational and cross-sectional. Obtaining the sample was through the records of individuals of long-stay institutions for the elderly in the city of Natal, RN. The elderly were evaluated through the Mini Nutritional Assessment (MNA) and triceps skinfold (TSF) and each senior or caregiver answered a questionnaire about information like type and dietary restrictions, accessibility to food, use of alcohol and tobacco, practice physical activity and appetite. Variables such as age, gender, education, marital status, time that the elderly living in the institution, the reason for the institutionalization and comorbidities were taken from the records of each senior. The frequency of food consumption of various food groups was assessed from the questionnaire frequency of feeding study Health, Wellbeing and Aging (HWA). Data were presented as means and standard deviations, absolute and relative frequencies. To analyze the frequency of consumption, there was a factor analysis with extraction of factors from the principal components analysis with varimax rotation. A bivariate analysis was performed using the chi-square and the magnitude of the effect observed by prevalence ratio (95% CI). The Poisson regression assessed the net effect of independent variables on the two outcomes, considering a significance level of 5%. We studied twelve Homes for the Aged totaling 381 seniors eligible for the study. The prevalence of risk of malnutrition was 46.1% (45.9 to 46.2) and malnutrition was 31.4% (31.2 to 31.5). The risk of malnutrition was significantly associated with the presence of urinary incontinence (RP = 1.444, 1.113 to 1.874) was associated with malnutrition and lack of appetite (RP = 1.757, 1.246 to 2.476), the fact that the individuals do not have access to food outside the institution (RP = 0.565, 0.337 to 0.946), low water consumption (RP = 1.646, 1.101 to 2.459) and dementia (PR = 1.537, 1.072 to 2.204). The high prevalence of malnutrition and risk of malnutrition in the study suggests that we should pay attention to information related to eating habits and the presence of comorbidities, as these can influence the nutritional status of this population

Proposta de questionário para caracterização da prevalência de sintomas digestivos nas doenças difusas do tecido conjuntivo

RACIONAL: As doenças difusas do tecido conjuntivo afetam vários sistemas orgânicos, inclusive o digestório. Neste, as lesões variam em intensidade e freqüência na dependência da doença envolvida. A descrição das diferentes manifestações digestivas tem sido pouco freqüente, pouco detalhada e, não raro, baseada em experiências individuais e levantamentos retrospectivos. Tais formas de registro de dados produzem resultados muitas vezes conflitantes entre as diferentes casuísticas. OBJETIVO: Estabelecer de forma mais consistente, por intermédio de entrevista e questionário predefinido de sintomas, o conjunto e freqüência dos sintomas digestivos observados na esclerose sistêmica progressiva, artrite reumatóide, polimiosite/dermatomiosite, doença mista do tecido conjuntivo e lúpus eritematoso sistêmico. PACIENTES E MÉTODO: Estudaram-se 99 pacientes, 90% mulheres, com idade média de 45 anos. do total, 35 tinham artrite reumatóide, 26 esclerose sistêmica progressiva, 21 lúpus eritematoso sistêmico, 12 dermatomiosite/polimiosite e 5 doença mista do tecido conjuntivo. Todos foram submetidos, por investigador treinado, a entrevista e preenchimento de um questionário de sintomas digestivos, composto de 17 itens, previamente definidos. RESULTADOS: O estudo revelou elevada prevalência de sintomas gastrointestinais nas cinco doenças investigadas, muitas vezes afetando mais de 50% dos casos. Chamou a atenção a presença significativa de sintomas negligenciados pela literatura como a incontinência fecal. Discordante de trabalhos anteriores, os pacientes desta série com artrite reumatóide apresentaram variadas queixas digestivas, surpreendendo o achado de disfagia em 1/3 deles. CONCLUSÕES: As doenças difusas do tecido conjuntivo são causas de freqüentes e numerosos sintomas digestivos. O uso de questionários predefinidos mostrou-se instrumento válido na identificação de substancial número de sintomas, alguns deles ainda não referidos pela literatura. Por fim, foi constatada escassez de trabalhos passados e atuais relativos às manifestações gastrointestinais das doenças difusas do tecido conjuntivo, o que prejudicou análises comparativas mais amplas.

Estratégias de enfrentamento da incontinência urinária por mulheres

Este artigo é parte de uma pesquisa qualitativa mais abrangente que utilizou como referencial teórico-metodológico a Grounded Theory e o Interacionismo Simbólico, resultando no modelo teórico denominado Entre o sofrimento e a esperança: a reabilitação da incontinência urinária como componente interveniente. Com a intenção de comunicar todo o conhecimento produzido, apresenta-se parte desse modelo, referente ao processo de enfrentamento da incontinência urinária por mulheres sem perspectivas de acesso ao tratamento cirúrgico, após falha dos procedimentos conservadores. Ao inter-relacionar os componentes (categorias e subcategorias) relativos à experiência dessas mulheres, buscando compará-los e analisá-los para compreender a interação entre eles, notou-se vulnerabilidade moral e psicossocial no movimento da experiência do grupo, suscetibilizando-o a riscos à saúde e ao comprometimento da qualidade de vida. Pesquisas são necessárias para aprofundar a compreensão de experiências em que haja barreira ao tratamento cirúrgico por descrédito do profissional médico sobre sua efetividade.

Quality of life in women with vulvar cancer submitted to surgical treatment: a comparative study

Objectives: To investigate the occurrence and severity of lymphoedema of the lower extremities (LLE), quality of life (QoL), and urinary and sexual dysfunction in women with vulvar cancer submitted to surgical treatment.Study design: Twenty-eight patients with vulvar cancer submitted to vulvectomy and inguinofemoral lymphadenectomy and 28 healthy, age-matched women (control group) were evaluated. The occurrence and severity of LLE were determined by Miller's Clinical Evaluation. QoL, urinary function and sexual function were assessed by the EORTC QLQ-C30, SF-ICIQ and FSFI questionnaires, respectively. The differences between groups and correlations were assessed using Student's r-test, Chi-squared test, Mann-Whitney U-test and Spearman's rho test.Results: The groups were similar in terms of marital status, educational status, menopausal status, hormone therapy and height. The occurrence and severity of LLE were higher in women with vulvar cancer compared with the control group (p < 0.001 and p = 0.003, respectively). A significant association was found between the severity of LLE and advanced age (p = 0.04), and the severity of LLE and higher body mass index (BMI; p = 0.04) in patients with vulvar cancer. In the patients with vulvar cancer, there was a significant correlation between the severity of LLE and worse QoL in the following domains: physical, cognitive, emotional, social, fatigue, pain, sleep and financial questions (p < 0.05). There was no difference in urinary function between the two groups (p = 0.113). Age and number of deliveries were the only variables associated with the occurrence of urinary incontinence (p = 0.01). Urinary incontinence was present in women with a mean age of 74.9 +/- 4.6 years and a mean of 7.3 +/- 1.3 normal deliveries. There was no difference between the groups in terms of the sexual function. Multivariate analysis showed an association between sexual function and age (p = 0.01), and sexual function and being in a stable relationship (p = 0.02).Conclusion: Patients submitted to vulvectomy or inguinofemoral lymphadenectomy for vulvar cancer are at higher risk of developing LLE compared with healthy, age-matched women. This has a negative effect on QoL, but does not interfere with urinary or sexual function. (C) 2012 Elsevier B.V. All rights reserved.

Effect of intravaginal electrical stimulation on pelvic floor muscle strength

The aim of this study was to evaluate the effect of intravaginal electrical stimulation (IES) on pelvic floor muscle (PFM) strength in patients with mixed urinary incontinence (MUI). Between January 2001 and February 2002, 40 MUI women (mean age: 48 years) were studied. Urge incontinence was the predominant symptom; 92.5% also presented mild stress urinary incontinence (SUI). Selection criteria were clinical history and urodynamics. Pre-treatment urodynamic study showed no statistical differences between the groups. Ten percent of the women in each group had involuntary detrusor contractions. Patients were randomly distributed, in a double-blind study, into two groups. Group G 1 (n=20), effective IES, and group G2 (n=20), sham IES, with follow-up at 1 month. The following parameters were studied: (1) clinical questionnaire, (2) examiner's evaluation of perineal muscle strength, (3) objective evaluation of perineal muscle by perineometry, (4) vaginal weight test, and (5) urodynamic study. The IES protocol consisted of three 20-min sessions per week over a 7-week period using a Dualpex Uro 996 at 4 Hz. There was no statistically significant difference in the demographic data of both groups. The number of micturitions per 24 h after treatment was reduced significantly in both groups. Urge incontinence, present in all patients before treatment, was reduced to 15% in G1 and 31.5% in G2 post-treatment. The subjective evaluation of PFM strength demonstrated a significant improvement in G1. Objective evaluation of PFM force by perineometer showed a significant improvement in maximum peak contraction post-treatment in both groups. In the vaginal weight test, there was a significant increase in average number of cone retentions post-treatment in both groups. With regard to satisfaction level, after treatment, 80% of the patients in G1 and 65% of the patients in G2 were satisfied. There was no statistically significant difference between the groups. There was a significant improvement in PFM strength from both effective and sham electrostimulation, questioning the effectiveness of electrostimulation as a monotherapy in treating MUI.

Pelvic floor muscle evaluation in incontinent patients

The aim of this study was to assess pelvic floor muscle (PFM) strength and perception and its correlation with stress urinary incontinence (SUI). One hundred and one women were divided into two groups according to the presence (G1=51 patients) or absence (G2=50 patients) of SUI. Subjective [urine stream interruption test (UST), visual survey of perineal contraction and transvaginal digital palpation to assess pelvic muscle contraction] and objective evaluations of pelvic floor muscles in all patients were performed (vaginal manometry). During the UST, 25.5% of G1 patients and 80% of G2 patients were able to interrupt the urine stream (p<0.05). Digital evaluation of pelvic muscular contraction showed higher strength in G2 than in G1 patients (p<0.0001). Perineometer evaluation of PFM strength was significantly higher in the continent group (p<0.001). Pelvic floor muscle weakness in incontinent patients demonstrates the importance of functional and objective evaluation of this group of muscles.

Clinical and quality-of-life outcomes after autologous fascial sling and tension-free vaginal tape: a prospective randomized trial

Purpose: Evaluate the impact autologous fascial sling (AFS) and tension-free vaginal tape (TVT) procedures on quality-of-life in incontinent women. Materials and Methods: Forty-one women were randomly distributed into two groups. Group G1 (n = 21), underwent AFS and group G2 (n = 20) TVT implant. The clinical follow up was performed at 1, 6, 12 and 36 months. Results: TVT operative time was significantly shorter than AFS. Cure rates were 71% at 1 month, 57% at 6 and 12 months in G1. In G2, cure rates were 75% at 1 month, 70% at 6 months and 65% at 12 months; there was no significant difference between groups. As regards the satisfaction rate, there was no statistical difference between groups. Analysis of quality of life at 36 months revealed that there was no significant difference between groups. Conclusion: Similar results between AFS and TVT, except for operative time were shorter in TVT.

Urodinâmica convencional versus cistometria simplificada para caracterização da incontinência urinária feminina

OBJETIVO: avaliar a concordância dos diferentes parâmetros urodinâmicos comparados à cistometria simplificada, permitindo uma diminuição na relação custo-benefício no diagnóstico da incontinência urinária de esforço (IUE) na mulher. MÉTODOS: foram coletadas e avaliadas retrospectivamente as informações contidas dos prontuários de trinta pacientes acompanhadas, no período de janeiro de 2000 a março de 2001. Todas foram submetidas a exame físico geral e ginecológico. O estudo urodinâmico foi realizado pela técnica convencional, utilizando-se aparelho Dynograph Recorder R-611. A cistometria simplificada foi realizada com auxílio de um equipo em Y de PVC (pressão venosa central), conectado a um sonda de Foley 14 F, que permitia tanto a infusão de soro fisiológico como a captação da pressão intra-vesical. Foram analisados os parâmetros: volume residual, capacidade vesical, complacência, presença de contrações involuntárias do detrusor e perdas urinárias aos esforços. Para determinação da proporção de concordância entre os métodos foram utilizados o teste de concordância de Pearson e o teste de Wilcoxon, para amostras relacionadas. RESULTADOS: a média de idade foi de 50 anos, com extremos variando de 28 a 70 anos. O índice de concordância entre os estudos, na demonstração das perdas urinárias aos esforços, foi de 67%. Para a detecção das contrações involuntárias do detrusor, a proporção de concordância foi de 90%. A média do volume residual encontrado na cistometria simplificada foi de 16,8 ml contra 2 ml da urodinâmica convencional, com diferença significativa (p < 0,01). A média de capacidade vesical máxima no estudo urodinâmico foi de 440,5 ml, enquanto que, na cistometria simplificada, foi de 387 ml (p < 0,05). A complacência vesical foi, em média, significativamente maior na cistometria simplificada (43,0 ml/cmH2O) quando comparada ao estudo urodinâmico (31,5 ml/cmH2O), com p < 0,01. CONCLUSÃO: Avaliações preliminares sugerem que a propedêutica uroginecológica associada à cistometria simplificada é uma opção a ser considerada na avaliação clínica e pré-operatória de pacientes com IUE em substituição à urodinâmica convencional, particularmente onde esta última não se encontra disponível. A cistometria simplificada é um exame acessível que é capaz de detectar contrações involuntárias do detrusor, assim como identificar perdas urinárias com relativa sensibilidade, proporcionando ao examinador noções fidedignas do comportamento vesical.

Surgical procedures used for post-traumatic neurogenic bladder in a cat: report case

Um gato de um ano de idade, macho, castrado, sem raça definida, foi encaminhado ao Hospital Veterinário Escola para avaliação de retenção urinária associada à subluxação nas vértebras T12-T13, que foi causada por um acidente automobilístico. Realizou-se a denervação do esfíncter uretral, por transecção dos nervos pudendo e hipogástrico, para permitir o esvaziamento da bexiga, porém três meses após a cirurgia inicial o animal apresentou recorrência da retenção urinária. Esfincterotomia endoscópica uretral foi então realizada, resultando em incontinência urinária por quatro meses.

Digestibilidade aparente de rações contendo levedura íntegra, levedura autolisada e parede celular pela tilápia do Nilo

Apparent digestibility coefficient of dry matter, crude protein, ether extract, gross energy, of diets supplemented with spray dried whole yeast (1.0; 2.0 e 3.0%), autolyzed (1.0; 2.0 e 3.0%), yeast cell wall (0.1; 0.2 e 0.3%) plus a additional diet with no yeast and yeast derivatives were evaluated to Nile tilapia. Eighty juveniles (83.0+/-8.5g) were placed in eight 250L aquaria for feeding and four aquaria of the same volume for collecting faecal samples. Both sets were equipped with flow-trough recirculation system provided with mechanical and biological filter. Diets supplemented with whole yeast, autolyzed yeast, and yeast cell wall presented, as mean, superior apparent coefficient digestibility than control. It can be concluded that supplementation of yeast and yeast derivatives improve apparent coefficient digestibility of experimental diets and diets supplemented with estimated level of 2.13-2.36% autolyzed yeast shows better digestibility.

Detection of turkey coronavirus in commercial turkey poults in Brazil

Poult enteritis complex has been incriminated as a major cause of loss among turkey poults in other countries. We have observed this in Brazil, associated with diarrhoea, loss of weight gain and, commonly, high mortality In this study, we have used the reverse transcriptase polymerase chain reaction (RT-PCR) to detect turkey coronavirus (TCoV) in sick poults 30 to 120 days of age from a particular producer region in Brazil. The RT-PCR was applied to extracts of intestine tissue suspensions, and the respective intestinal contents, bursa of Fabricius, faecal droppings and cloacal swabs. Primers were used to amplify the conserved 3' untranslated region of the genome, and the nucleocapsid protein gene of TCoV Histo pathological and direct immunohistochemical examinations were performed to detect TCoV antigen in infected intestine and bursa slides. All the results from stained tissues revealed lesions as described previously for TCoV infection. The direct immunohistochemical positive signal was present in all intestine slides. However, all bursa of Fabricius tissues analysed were negative. RT-PCR findings were positive for TCoV in all faecal droppings samples, and in 27% of cloacal swabs. Finally, the best field material for TCoV diagnosis was faecal droppings and/or intestine suspensions.
