Ethical challenges associated with providing continence care in residential aged care facilities : findings from a grounded theory study

A person-centred approach to care in residential aged care facilities should uphold residents’ rights to independence, choice, decision-making, participation, and control over their lifestyle. Little is known about how nurses and personal care assistants working in these facilities uphold these ideals when assisting residents maintain continence and manage incontinence. The overall aim of the study was to develop a grounded theory to describe and explain how Australian residents of aged care facilities have their continence care needs determined, delivered and communicated. This paper presents and discusses a subset of the findings about the ethical challenges nurses and personal care assistants encountered whilst providing continence care. Grounded theory methodology was used for in-depth interviews with 18 nurses and personal care assistants who had experience of providing, supervising or assessing continence care in any Australian residential aged care facility, and to analyse 88 hours of field observations in two facilities. Data generation and analysis occurred simultaneously using open coding, theoretical coding, and selective coding, until data were saturated. While addressing the day-to-day needs of residents who needed help to maintain continence and/or manage incontinence, nurses and personal care assistants struggled to enable residents to exercise choice and autonomy. The main factor that contributed to this problem was that the fact that nurses and personal care assistants had to respond to multiple, competing, and conflicting expectations about residents’ care needs. This situation was compounded by workforce constraints, inadequate information about residents’ care needs, and an unpredictable work environment. Providing continence care accentuated the ethical tensions associated with caregiving. Nurses’ and personal care assistants’ responses were mainly characterised by highly protective behaviours towards residents. Underlying structural factors that hinder high quality continence care to residents of aged care facilities should be urgently addressed.

Composition of fuel stores and digestive limitations to fuel deposition rate in the long-distance migratory thrush nightingale, Luscinia luscinia

During their autumn migratory phase, thrush nightingales (Luscinia luscinia) previously starved for 2 d were allowed to refuel under three different ambient temperature conditions (-7 degrees, 7 degrees, and 22 degrees C). During the refueling period, as well as during the preceding control and starvation periods, food intake, body mass, and feces production were monitored. In addition, daily energy expenditure was measured during the refueling period. The compilation of the energy balance during the refueling period revealed an energy density of the deposited tissue of 33.6 kJ g-1. Assuming that the deposited tissue consists of fat and protein exclusively, with energy densities of 39.6 and 5.5 kJ g-1 wet mass, respectively, we estimated the deposited tissue to consist of 82% fat and 18% wet protein (6% dry protein and 12% water). Nitrogen balances during control, starvation, and refueling phases and during a period of prolonged and complete starvation indicated that 5% of the nutrient stores consisted of dry protein. Our results support recent findings that nutrient stores for migration often contain protein in addition to fat and consequently are 15%-25% less energy rich than pure fat stores. These proteins might be stored as muscle or other functional tissue and may be required to support the extra mass of the stores and/or reflect an incapacity of the metabolic machinery to catabolize far exclusively. Fuel deposition rate was positively related with ambient temperature, whereas food intake rate was unaffected by temperature. These results indicate that the rate of fuel deposition is limited by a ceiling in food intake rate; when this ceiling is reached, fuel deposition rate is negatively affected by daily energy expenditure rate. To a certain extent, the ceiling in food intake rate varies depending on feeding conditions over the previous days. These variations in food intake capacity probably reflect the building and breakdown of gut tissues and/or gut enzyme systems and might be insensible and not evolutionary adaptive. Significant energetic costs, however, are probably associated with the maintenance of gut tissues. It is therefore feasible that changes in digestive capacity are regulated and are directed at energy economization.

Night-time continence care in Australian residential aged care facilities: findings from a grounded theory study

BACKGROUND: Continence care commonly disrupts sleep in residential aged care facilities, however, little is known about what staff do when providing continence care, and the factors that inform their practice. AIMS: To describe nurses' and personal careworkers' beliefs and experiences of providing continence care at night in residential aged care facilities. METHODS/DESIGN: Eighteen nurses and personal careworkers were interviewed about continence care, and 24 hours of observations were conducted at night in two facilities. RESULTS/FINDINGS: Most residents were checked overnight. This practice was underpinned by staffs' concern that residents were intractably incontinent and at risk of pressure injuries. Staff believed pads protected and dignified residents. Decisions were also influenced by beliefs about limited staff-to-resident ratios. CONCLUSION: Night-time continence care should be audited to ensure decisions are based on residents' preferences, skin health, sleep/wake status, ability to move in bed, and the frequency, severity and type of residents' actual incontinence.

Fear and overprotection in Australian residential aged care facilities: the inadvertent impact of regulation on quality continence care

Aim: Most residents in residential aged care facilities are incontinent. This study explored how continence care was provided in residential aged care facilities, and describes a subset of data about staffs' beliefs and experiences of the quality framework and the funding model on residents' continence care.

Methods: Using grounded theory methodology, 18 residential aged care staff members were interviewed and 88 hours of field observations conducted in two facilities. Data were analysed using a combination of inductive and deductive analytic procedures.

Results: Staffs' beliefs and experiences about the requirements of the quality framework and the funding model fostered a climate of fear and risk adversity that had multiple unintended effects on residents' continence care, incentivising dependence on continence management, and equating effective continence care with effective pad use.

Conclusion: There is a need to rethink the quality of continence care and its measurement in Australian residential aged care facilities.

Comparação de diferentes etapas de enriquecimento seletivo no isolamento de Salmonella sp. a partir de fezes de suínos de terminação

A detecção de Salmonella sp. é fundamental nos programas de controle de salmonelose. Métodos de detecção mais eficientes permitem uma melhor determinação do nível de infecção dos rebanhos, um melhor entendimento da epidemiologia da infecção por Salmonella sp. e o desenvolvimento de programas de controle do patógeno, que visem a segurança biológica do alimento. Nos métodos convencionais, o enriquecimento seletivo é uma etapa crítica, pois inibe a microbiota competitiva e permite a multiplicação de Salmonella sp. Vários caldos de enriquecimento seletivo têm sido comparados quanto à eficiência na recuperação de Salmonella sp. a partir de alimentos, contudo existem poucos estudos relativos a fezes de suínos. O objetivo deste trabalho foi comparar caldos de enriquecimento seletivo para o isolamento de Salmonella sp. a partir de fezes de suínos. Numa primeira fase, amostras de fezes foram contaminadas artificialmente e os caldos Rappaport-Vassiliadis incubado a 42°C (RV), Tetrationato Müller-Kauffmann a 37°C (TMK37) e 42°C (TMK42), e Selenito Cistina (SC) a 37°C foram testados, em associação com meios sólidos seletivos: Rambach (RA), Xilose Lisina Tergitol 4 (XLT4), e Verde Brilhante Vermelho de Fenol Lactose Sacarose (VB). Na segunda fase os caldos RV, TMK37 e TMK42, semeados nos meios XLT4 e VB, foram testados com amostras naturalmente contaminadas. Na primeira fase o RV, TMK42 e TMK37 foram mais eficientes que o SC. No isolamento de Salmonella sp. em amostras naturalmente contaminadas os caldos TMK42 e RV foram superiores ao TMK37. O desempenho destes influenciou diretamente a capacidade seletiva e indicadora dos meios sólidos seletivos. No presente estudo, a associação TMK42/XLT4 demonstrou ser mais sensível, e a RV/XLT4 mais específica. O ágar VB também é recomendado para aumentar a probabilidade de detecção do patógeno. Desta forma os caldos RV e TMK42 e o ágar XLT4 e o VB foram considerados os mais indicados para a implantação de protocolos de detecção de Salmonella sp. em fezes suínas.

Associação entre manometria ano-retal e neuropatia pudenda em pacientes com incontinência fecal

A incontinência fecal é a incapacidade de manter o controle da eliminação do conteúdo intestinal em local e tempo socialmente adequados, resultando em escape de gases e fezes. Esta condição acarreta grande prejuízo na vida social dos acometidos. A causa conhecida mais comum é o trauma perineal, porém em uma grande proporcão a incontinência é idiopática. A avaliação da função esfincteriana anal é fundamental para o diagnóstico e para a conduta terapêutica na incontinência fecal. Para o entendimento da fisiopatologia desta condição desenvolveram-se vários exames de investigação. A manometria ano-retal é considerado imprescindível na avaliação. A correlação dos dados da manometria com a gravidade da doença e com estudos eletrofisiológicos ainda não estão bem estabelecidos. O objetivo deste estudo é correlacionar os dados da manometria ano-retal e o estudo do tempo de latência motora terminal do nervo pudendo com a incontinência fecal e comorbidades. Foram estudados prospectivamente todos os pacientes com queixa clínica de incontinência fecal atendidos no ambulatório de Serviço de Coloproctologia do Hospital Nossa Senhora da Conceição, de Porto Alegre (RS), entre março de 1997 e junho de 2000. De todos os pacientes foram coletados dados da anamnese que os classificaram segundo escore de incontinência proposto por JORGE & WEXNER (1993). Todos foram submetidos a manometria ano-retal, estudo do tempo de latência motora terminal do nervo pudendo bilateralmente e exame proctológico. Foram excluídos os pacientes que não concluíram toda a investigação, com cirurgias colo-retais baixas prévias ou neoplasia de reto e canal anal. Para análise estatística, os pacientes foram separados em grupos segundo a manometria normal ou alterada (hipotonia), presença ou não de neuropatia de nervo pudendo, por idade e por sexo. Foram estudados 39 pacientes, 85,6% do sexo feminino com idade média de 60,1 anos (±12,89). A média do escore de incontinência fecal foi de 9,30±4,93. À manometria ano-retal, vinte e três pacientes (59%) apresentaram pressões reduzidas. As pressões foram significativamente mais elevadas nos pacientes do sexo masculino. O tempo de latência motora terminal do nervo pudendo (neuropatia) foi prolongado em 14 doentes (35,9%). A idade e o tempo de latência motora terminal do nervo pudendo correlacionaram-se significativamente, r=0,422, (P=0,007). A demais correlações entre idade, pressões da manometria, tempo de latência motora terminal do nervo pudendo e escore de incontinência não foram estatisticamente significativas.

Isolamento e caracterização de Salmonella sp. em suínos ao abate e em cortes de pernil

A Salmonella sp. é uma das principais causas de doenças transmitidas por alimentos, principalmente de origem animal. Os suínos podem ser portadores assintomáticos de Salmonella sp. e, nessa condição, serem levados ao abate. Desta forma, a entrada de Salmonella sp. na cadeia de produção é uma preocupação para a indústria. Sabendo-se da importância deste microrganismo, pelo seu impacto na indústria e na saúde pública, este trabalho teve como objetivo determinar a prevalêncía de Salmonella sp. em suínos levados ao abate em um frigorífico sob inspeção federal no Rio Grande do Sul, e correlacionar com a contaminação de cortes de pernil. Para tanto, 64 amostras de conteúdo intestinal e 121 amostras de cortes de pernil coletadas em 4 visitas, foram submetidas ao isolamento e identificação de Salmonella sp. As amostras de Salmonella sp. foram avaliadas quanto a resistência a 14 antimicrobianos, através da técnica de difusão em ágar. Salmonella sp. foi isolada de 46,87% das amostras de conteúdo intestinal e de 49,59% dos cortes de pernil. Foi encontrado grande número de sorovares, sendo os mais prevalentes Panama e Bredeney. Das amostras isoladas, 60,8% apresentaram perfil de multiresistência, sendo os maiores índices de resistência a sulfonamida, ácido nalidíxico e tetraciclina. Utilizando o perfil de resistência a antimicrobianos de amostras de um mesmo sorovar forma comparadas quanto a sua similaridade e agrupadas em dendrogramas, observou-se grande diversidade nas linhagens isoladas. Os resultados demonstraram que a entrada de animais no frigorífico excretando Salmonella sp., pode contribuir para a contaminação do produto final. A diversidade de sorovares e linhagens pode representar que são várias as fontes de contaminação, tanto dos animais quanto do produto final.

Fecal androgen levels in common marmoset (Callithrix jacchus) males living in captive family groups

In captive common marmoset groups, the reproductive inhibition observed in subordinate female seems to be a result of olfactory, visual and behavioral cues from the dominant female. However, few studies have examined the relationship among adult males living in the same social group. These studies have shown that reproductive failure among peer males seems to be based on hormonal and behavioral mechanisms. New insights on sexual strategies in primates have been shown using fecal steroids, but so far no information is available for common marmoset males. In the present study, we evaluated the influence of light-dark cycle, age and reproductive condition on the profile of fecal androgens in males living in the same family group. Feces were collected from six fathers and six sons for androgen determination during the light phase of the 24-h cycle for eight days randomly distributed over a 4-week period. Androgen levels were determined by enzyme immunoassay technique. Adult sons showed higher androgen levels (166.97 ± 22.95 ng/g) than fathers (80.69 ± 44.38 ng/g) and juveniles (49.06 ± 23.15 ng/g; P < 0.05). No diurnal variation (P > 0.05) in fecal androgen profile was observed in adults or juveniles. No indication of androgen-mediated social competition between fathers and adult sons was demonstrable. These results provide basic information on fecal androgen profile useful to investigate the socioendocrinology of free-ranging common marmoset males and verify that, in contrast to daughters, the reproductive suppression of sons is not based on physiological inhibition of their gonads

Cuidados de enfermagem ao paciente em pós-operatório de prostatectomia: revisão integrativa

Este estudo trata-se de revisão integrativa da literatura com objetivo de sintetizar o conhecimento produzido em artigos sobre os cuidados de enfermagem aos pacientes em pós-operatório de prostatectomia. Para seleção dos artigos foram consultadas cinco bases de dados – SCOPUS, CINAHL, PUBMED, LILACS e Cochrane – sendo incluídos dezenove artigos. Os resultados mostram estudos que se enquadram nos níveis II, IV, V, VI e VII de evidência, a maioria realizada nos Estados Unidos durante os anos de 1999 a 2011. Os cuidados de enfermagem identificados foram agrupados em seis categorias: acompanhamento psicológico, orientações pós-operatórias, tratamento da disfunção erétil, tratamento da incontinência urinária, tratamento da dor e tratamento da hiponatremia. Conclui-se que os estudos com maior nível de evidência identificado recomendam cuidados de enfermagem centrados no acompanhamento psicológico, nas orientações do período pós-operatório e no tratamento da disfunção erétil. Destaca-se ainda que tais recomendações concentram-se, sobretudo, nas ações de apoio emocional e educativo

Avaliação da incontinência urinária de esforço em mulheres na pós-menopausa com e sem queixa de perda urinária através da aplicação do pad-test de 1 hora

Stress urinary incontinence (SUI) is defined as "involuntary loss of urine" due to several processes that alter the ability of the bladder to hold urine properly, regarded as a social and hygienic problem that adversely affects quality of life. In postmenopausal women, IU is associated with atrophy and weakness of the pelvic floor muscles. The objective this study was investigate, using the onehour pad test, stress urinary leakage (SUI), evaluate and compare their results in postmenopausal and premenopausal women. The survey was characterized as a cross-sectional study. The study consisted of 60 postmenopausal women were divided into GIU - consisting of 34 volunteers complaining of involuntary loss of urine during stress - and GSIU - consisting of 26 volunteers without complaints of loss of urine during stress, and 15 women, during the premenopausal (GPM), and ovulatory with normal menstrual cycle. All volunteers were evaluated clinically, subjected to one-hour pad test, after the biochemical evaluation of blood and sex hormones. Statistical analysis was performed by descriptive analysis, ANOVA, Turkey´s post-test and Pearson correlation. The results showed that 100% of postmenopausal patients had involuntary loss of urine during one hour pad test (GIU: 4.0 g; GSIU: 4.5 g). GPM remained continent after an hour pad test (GPM: 0.4 g). In addition, Pearson showed a strong correlation between urine loss with time since menopause (r = 0.8, p <0.01) and body mass index - BMI (r = 0.7; p = 0.01). These data suggest that the one-hour pad test is a useful test to assess and quantify urinary leakage, including those volunteers who had no previous complaint of SUI

Occurrence of Cryptosporidium (Apicomplexa, Cryptosporidiidae) in Crotalus durissus terrificus (Serpentes, Viperidae) in Brazil

The objective of the present study was to investigate the prevalence of Cryptosporidium (Apicomplexa, Cryptosporidiidae) in the snake Crotalus durissus terrificus (Serpentes, Viperidae). Fifty animals were evaluated for the presence of oocysts of Cryptosporidium sp. at the time of arrival and 30 and 60 days later. Intestinal washings with saline solution (1% body weight), fecal samples, and organ scrapings were collected during the study. Oocysts were concentrated by an ether-phosphate-buffered saline sedimentation technique and then separated by a density gradient centrifugation technique. Smears were made with the sediment and submitted to modified acid-fast and auramine-rhodamine staining. Cryptosporidium-positive smears were used as controls for the experimental findings. The overall prevalence of Cryptosporidium sp. oocysts was 14%. Among the positive snakes, oocysts were detected only in the intestinal washing in two specimens, only in the feces in four specimens, and in both materials at least once in one specimen. The positive snakes were predominantly from Santa Maria da Serra city State of São Paulo (57.1%). We also observed that all of the examinations that presented positive results were obtained at least 27 days after the capture of the animals.
