High volume peritoneal dialysis vs daily hemodialysis: A randomized, controlled trial in patients with acute kidney injury

There is no consensus in the literature on the best renal replacement therapy (RRT) in acute kidney injury (AKI), with both hemodialysis (HD) and peritoneal dialysis (PD) being used as AKI therapy. However, there are concerns about the inadequacy of PD as well as about the intermittency of HD complicated by hemodynamic instability. Recently, continuous replacement renal therapy (CRRT) have become the most commonly used dialysis method for AKI around the world. A prospective randomized controlled trial was performed to compare the effect of high volume peritoneal dialysis (HVPD) with daily hemodialysis (DHD) on AKI patient survival. A total of 120 patients with acute tubular necrosis (ATN) were assigned to HVPD or DHD in a tertiary-care university hospital. The primary end points were hospital survival rate and renal function recovery, with metabolic control as the secondary end point. Sixty patients were treated with HVPD and 60 with DHD. The HVPD and DHD groups were similar for age ( 64.2 +/- 19.8 and 62.5 +/- 21.2 years), gender ( male: 72 and 66%), sepsis ( 42 and 47%), hemodynamic instability ( 61 and 63%), severity of AKI ( Acute Tubular Necrosis-Index Specific Score (ATN-ISS): 0.68 +/- 0.2 and 0.66 +/- 0.2), Acute Physiology, Age, and Chronic Health Evaluation Score (APACHE II) (26.9 +/- 8.9 and 24.1 +/- 8.2), pre-dialysis BUN (116.4 +/- 33.6 and 112.6 +/- 36.8mg per 100 ml), and creatinine ( 5.8 +/- 1.9 and 5.9 +/- 1.4 mg per 100 ml). Weekly delivered Kt/V was 3.6 +/- 0.6 in HVPD and 4.7 +/- 0.6 in DHD ( P<0.01). Metabolic control, mortality rate ( 58 and 53%), and renal function recovery ( 28 and 26%) were similar in both groups, whereas HVPD was associated with a significantly shorter time to the recovery of renal function. In conclusion, HVPD and DHD can be considered as alternative forms of RRT in AKI.

High volume peritoneal dialysis for acute renal failure

Background. Peritoneal dialysis (PD) is still widely used for acute renal failure (ARF) in developing countries despite concerns about its inadequacy. Continuous PD has been evaluated in ARF by analyzing the resolution of metabolic abnormality and normalization of plasma pH, bicarbonate, and potassium.Methodology: A prospective study was performed on 30 ARF patients who were assigned to high-dose continuous PD (Kt/V = 0.65 per session) via a flexible catheter (Tenckhoff) and automated PD with a cycler. Fluid removal, pH and metabolic control, protein Loss, and patient outcome were evaluated.Results: Patients received 236 continuous PD sessions; 76% were admitted to ICUs. APACHE II score was 32.2 +/- 8.65. BUN concentrations stabilized after 3 sessions, creatinine after 4, and bicarbonate and pH after 2. Fluid removal was 2.1 +/- 0.62 L/day. Creatinine and urea clearances were 15.8 +/- 4.16 and 17.3 +/- 5.01 mL/minute respectively. Normalized creatinine clearance and urea Kt/V values were 110.6 +/- 22.5 L/week/1.73 m(2) body surface area and 3.8 +/- 0.6 respectively. Solute reduction index was 41% +/- 6.5% per session. Serum albumin values remained stable in spite of considerable protein tosses (median 21.7 g/day, interquartile range 9.1 - 29.8 g/day). Regarding ARF outcome, 23% of patients presented renal function recovery, 13% remained on dialysis after 30 days of follow-up, and 57% died.Conclusion: High-dose continuous PD by flexible catheter and cycler was an effective treatment for ARF. It provided high solute removal, allowing appropriate metabolic and pH control, and adequate dialysis dose and fluid removal. Continuous PD can therefore be considered an alternative to other forms of renal replacement therapy in ARF.

Peritoneal dialysis in acute renal failure

The definition of adequate dialysis in acute renal failure (ARF) is complex and involves the time of referral to dialysis, dose, and dialytic method. Nephrologist experience with a specific procedure and the availability of different dialysis modalities play an important role in these choices. There is no consensus in literature on the best method or ideal dialysis dose in ARF. Peritoneal dialysis (PD) is used less and less in ARF patients, and is being replaced by continuous venovenous therapies. However, it should not be discarded as a worthless therapeutic option for ARF patients. PD offers several advantages over hemodialysis, such as its technical simplicity, excellent cardiovascular tolerance, absence of an extracorporeal circuit, lack of bleeding risk, and low risk of hydro-electrolyte imbalance. PD also has some limitations, though: it needs an intact peritoneal cavity, carries risks of peritoneal infection and protein losses, and has an overall lower effectiveness. Because daily solute clearance is lower with PD than with daily HD, there have been concerns that PD cannot control uremia in ARF patients. Controversies exist concerning its use in patients with severe hypercatabolism; in these cases, daily hemodialysis or continuous venovenous therapy have been preferred. There is little literature on PD in ARF patients, and what exists does not address fundamental parameters such as adequate quantification of dialysis and patient catabolism. Given these limitations, there is a pressing need to re-evaluate the adequacy of PD in ARF using accepted standards. Therefore, new studies should be undertaken to resolve these problems.

Comportamento de poedeiras criadas a diferentes densidades e tamanhos de grupo em ambiente enriquecido

The objective of this work was to determine the behavioral differences among laying hens reared at different densities and group sizes, in an enriched environment. Isa Brownlaying hens with ages from 30 to 32-week-old, in small-sized and deformed pens, were used. Hens were raised during 28 days in bays with shavings bedding, perch and nest. Two group sizes were evaluated (6 and 12 fowls) and at two rearing densities (774 and 1,440 cm2 by fowl) in a factorial arrangement with three replicates. In fifteen-minute video footages, it was recorded the frequency and the expression period for the following behavior were recorded: feather scratching, sand bath, wing beating, drinking water, pecking, head scratching, earth scratching, eating, perching, leg stretching, pursuing, sitting, and nest visiting. The treatments and the interaction between them had significant effects. The six-hen group increased the frequency of behavior types that indicate fowl frustration, regardless of density. The group size is the most important factor for hen well-being.

Percursos de uma poética de resíduos na obra de Carolina Maria de Jesus

A finalidade desse trabalho é discutir a problemática acerca da tensão produzida por variações de discursos, que cedem forma à experiência narrativa da “poeta do lixo” Carolina Maria de Jesus em seu diário/romance/reportagem Quarto de despejo: diário de uma favelada (1960). Entendemos que sua literatura é marcada por uma mistura de estilos literários desterritorializados, sendo capaz de ativar uma linha de fuga em relação às literaturas canonizadas. Nisso incide a caracterização desse tipo de composição artística, comum em países de formações culturais híbridas. Observamos nesse texto a presença de uma potência rizomática que consiste justamente na reformulação de elementos que compõem esta poética de resíduos justapostos numa certa “deformidade” estilística para além de livros em registro. Notamos que, assim como a escritora reciclava lixo para comer, também o fazia com os discursos de sua poética. Renova por tentar administrar e, conseqüentemente, reestruturar os sentidos de nosso sistema social, no campo da arte escrita, de maneira intuitiva pois, como sabemos, não possuía um projeto literário como os escritores tradicionais.

Iracema, de José de Alencar, e as Heroides, de Ovídio

Manuais de literatura ensinam que o Romantismo, centrado no eu romântico em seus conflitos e anseios libertários, rompe com os códigos clássicos da poética do Arcadismo. Em Iracema: a lenda do Ceará, Alencar narra a união da índia Iracema com Martim, o colonizador português que a fascina, e dessa união nasce Moacir, fruto da primeira miscigenação de povos em terras brasileiras. A matéria-prima que Alencar ficcionalizou tem, por um lado, o componente histórico, pois personagens como o guerreiro Martim e o índio Camarão estão registradas nos anais da história; por outro lado, a construção da heroína assenta-se em figuras femininas da mitologia grega. Essa dívida com a tradição clássica, intermediada pelo poeta latino Ovídio, o próprio José de Alencar a reconhece em carta-posfácio, onde confessa ter composto “uma heroida que tem por assunto as tradições dos indígenas brasileiros e seus costumes. (ALENCAR, 1978, p.88).
