Abstract:
Objectives The aim of this study was to investigate the factors affecting recovery and durability of dialysis-independent renal function following commencement of peritoneal dialysis (PD). Design Retrospective, observational cohort study of the Australian and New Zealand PD patient population. Setting Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry. Participants The study reviewed all patients in Australia and New Zealand who commenced PD for treatment of end-stage renal failure between 15 May 1963 and 31 December 2004. Main Outcome Measures The primary outcomes examined were recovery of dialysis-independent renal function and time from PD commencement to recovery of renal function. A secondary outcome measure was time to renal death (patient death or recommencement of renal replacement therapy) following recovery of dialysis-independent renal function. Results 24663 patients commenced PD during the study period. Of these, 253 (1%) recovered dialysis-independent renal function. An increased likelihood of recovery was predicted by autoimmune renal disease, hemolytic-uremic syndrome, paraproteinemia, cortical necrosis, renovascular disease, and treatment in New Zealand. A reduced likelihood of recovery was associated with polycystic kidney disease and indigenous race. Analysis of a contemporary subset of 14743 patients in whom complete data were available for body mass index, smoking, and comorbidities yielded comparable results, except that increasing age was additionally associated with a decreased likelihood of recovery. Of the 253 patients who recovered renal function, 151 (60%) recommenced renal replacement therapy and 49 (19%) died within a median period of 226 days (interquartile range 110 – 581 days). The only significant predictors of continued renal survival after renal recovery were autoimmune renal disease and cortical necrosis. Conclusions Recovery of renal function in patients treated with PD is rare and determined mainly by renal disease type and race. In the majority of cases, recovery is short term. The apparently high rate of early patient death or return to dialysis after recovery of renal function on PD raises questions about the appropriateness of discontinuing PD therapy under such circumstances.

Abstract:
Intravenous albumin is recommended for hepatorenal disorders (HRD), but individuals who do not recover renal function may be at a high risk for pulmonary edema. We reviewed outcomes by the amount of albumin infused in 93 patients not receiving dialysis at admission but being treated with intravenous albumin for acute HRD at our institution. Absence of renal recovery was defined as no decrease in serum creatinine and requirement of dialysis during hospitalization, and partial renal recovery was defined as a decrease in serum creatinine but not to prehospitalization levels. Associations of clinical factors including total albumin infused, presence of renal recovery, and oliguria with the development of pulmonary edema during hospitalization were determined using logistic regression. Of the 93 patients, 20 patients had complete renal recovery, 17 patients had partial renal recovery, and 56 patients showed no renal recovery. Most patients received 300–600 g of albumin. Overall, 47.3% of patients developed pulmonary edema (n=44), but the risk was 75% in patients with oliguria on presentation and no renal recovery versus 17% in those with no oliguria and complete renal recovery (P<0.001). In the logistic regression model, oliguria (3.32; 95% confidence interval [CI]: 1.12, 9.81) and no renal recovery (3.38; 95% CI:1.24, 9.16) were each associated with higher odds of pulmonary edema after adjustment for covariates. No association was noted between total albumin infused and pulmonary edema. In summary, absence of renal recovery and oliguria in patients with HRD receiving intravenous albumin is associated with a higher risk of pulmonary edema.

Abstract:
Background. Acute kidney injury (AKI) is a common complication of treatment with liposomal amphotericin B (LAmB). The trajectory of renal recovery after LAmB-associated AKI has not been well described, nor has effect of LAmB dose on recovery of renal function been explored. Objective. Characterize the pattern of renal recovery after incident AKI during LAmB and determine potential influencing factors. Methods. This retrospective cohort study analyzed patients who developed a ≥50% increase in serum creatinine while on LAmB. Patients were followed up until complete renal recovery or death or for 30 days, whichever occurred first. The primary outcome was complete renal recovery, defined as serum creatinine convalescence to within 10% of the patient’s pretreatment baseline. Multivariable modeling was used to identify independent predictors of renal recovery. Results. Ninety-eight patients experienced nephrotoxicity during LAmB, 94% of which received doses <7 mg/kg/day. Fifty-one patients at least partially recovered renal function and, of these, 32 exhibited complete recovery after a mean 9.8 ± 7.8 days. No statistical relationship was found between LAmB dose at the time of AKI or cumulative exposure to LAmB and the likelihood of renal recovery. Concomitant nephrotoxins, age, and pretreatment renal function did not modify this effect in multivariable analysis. Conclusion and Relevance. Our data suggests that LAmB dose did not impact the likelihood of renal recovery. Additional investigation is needed to confirm these findings when aggressive dosing strategies are employe. Additional research is also warranted to further characterize the course of recovery after LAmB-associated nephrotoxicity and comprehensive spectrum of renal outcomes.

Abstract:
Background Reduced renal function is associated with worse renal outcome in patients with lupus nephritis (LN). However, there is insufficient knowledge regarding renal function recovery in patients with LN with reduced baseline renal function. Therefore, the present study aimed to investigate renal function recovery and related factors in patients with reduced baseline renal function. Methods The present retrospective longitudinal cohort study included patients with LN and reduced renal function. Reduced renal function was defined as an estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73 m2. Recovery of renal function was determined by an eGFR of >60 mL/min/1.73 m2 at six months after baseline, and factors associated with it were evaluated using logistic regression analysis. Results We included 90 patients with LN, with a mean eGFR value of 37.2 ± 13.9 mL/min/1.73 m2. Forty-six (51.1%) patients recovered their renal function after six months. On multivariate analysis, hydroxychloroquine use (odds ratio (OR) = 3.891, 95% confidence interval (CI) 1.196–12.653, p = 0.024), prolonged LN (OR = 0.926, 95% CI 0.874–0.981, p = 0.009) and high-grade tubular atrophy (OR = 0.451, 95% CI 0.208–0.829, p = 0.013) were associated with renal function recovery. During follow up, 25 patients were on end-stage renal disease (ESRD). Kaplan–Meier analysis revealed that renal function recovery after six months and lower probability of ESRD are associated. Conclusions In patients with LN and reduced renal function, renal function recovery at six months was associated with use of hydroxychloroquine and inversely related to longer duration of LN and higher grade of tubular atrophy.

Abstract:
We report a case of the deliberate inhalation of a toluene-containing adhesive which caused acute renal failure and hepatic damage. Renal biopsy disclosed a severe tubulo-interstitial nephritis, renal function recovered after 14 days' haemodialysis. The literature on renal complications of toluene exposure is reviewed, this is the only case of acute renal failure due to interstitial nephritis after toluene exposure with subsequent recovery. Recovery in this case may have been related to the avoidance of further toluene exposure.

Abstract:
Introdução: Estudos recentes mostram que pacientes com lesão renal aguda apresentam maior mortalidade em longo prazo e evoluem mais para doença renal crônica do que pacientes com controles sem lesão renal aguda. Os fatores associados à pior evolução desses pacientes são controversos e suas causas de óbito desconhecidas. Objetivos: Avaliar a sobrevida e as causas de óbito após a alta hospitalar de pacientes com lesão renal aguda. Analisar a recuperação da função renal na alta hospitalar e a sua evolução em longo prazo. Métodos: Estudo retrospectivo de pacientes internados em 2005 e 2006 com lesão renal aguda e que tiveram lata hospitalar livres de diálise. Foram analisadas as suas características clínicas e laboratoriais, e verificadas a mortandade e a evolução da função renal até 31 de maio de 2008. As causas de óbito foram pesquisadas no \"Programa de Aprimoramento das Informações de Mortalidade\" da cidade de São Paulo e comparadas com a população geral da mesma faixa etária. A curva de sobrevida dos pacientes com lesão renal aguda foi comparada com a da população de São Paulo. A evolução da filtração glomerular durante o primeiro ano após a alta hospitalar foi avaliada considerando-se os valores da creatina sérica encontradas em medidas ambulatoriais. Resultados: Foram incluídos 507 pacientes que foram seguidos por um tempo mediano de 21 meses. Ao final do estudo 38% haviam morrido. As principais causas de óbito foram doenças do aparelho circulatório e neoplasias, achado semelhante ao da população de São Paulo. A causa de óbito se relacionou com a presença de comorbidades existentes antes da lesão renal aguda. A sobrevida dos pacientes foi pior do que a da população de São Paulo e os fatores associados à sua pior sobrevida foram a presença de hepatopatia, índice de Khan de alto risco, internação em serviço clínico e novo episódio de lesão renal aguda na mesma internação. Na alta hospitalar, 50% dos pacientes apresentavam recuperação completa da função renal, 36% recuperação parcial e 14% não tinham recuperado a função renal. Os fatores associados com a recuperação completa da função renal foram: menor gravidade na lesão renal aguda, presença de provável doença renal crônica e necessidade de ventilação mecânica. O estudo da evolução da função renal se restringiu a 278 pacientes. Estes mostraram dois tipos de comportamento: aqueles com recuperação completa da função renal apresentavam, na alta hospitalar, um filtração glomerular maior do que a referência, e estes valores foram se aproximando ao longo do primeiro ano após a alta. Já aqueles com recuperação parcial e os que não recuperaram a função renal evoluíram com melhora da filtração glomerular durante o primeiro ano, porém sem atingir os valores de referência. Conclusões: Os pacientes que apresentam lesão renal aguda mantêm uma alta mortalidade após a alta hospitalar que está relacionada à presença de comorbidades anteriores à internação. Somente metade dos pacientes apresenta recuperação completa da função renal na alta hospitalar, e a recuperação está associada à menor gravidade da lesão renal aguda. A ausência de informação sobre a função renal após a alta hospitalar ocorreu em 25% dos pacientes. No primeiro ano após a alta hospitalar a filtração glomerular tende a se aproximar dos valores de referência, porém sem atingi-los.
Introduction: Recent studies show that the patients who suffered an acute kidney injury episode have increased long-term mortality and develop more chronic kidney disease than those without acute kidney injury. Factors associated with this poor outcome are controversial, and causes of death of these patients are unknown. Objectives: To evaluate survival and causes of death after hospital discharge of patients with acute kidney injury. To analyze the recovery of renal function at hospital discharge its long-term outcome. Methods: A retrospective study of patients hospitalized in 2005 and 2006 with acute kidney injury who were discharged free of dialysis. We analyzed their clinical and laboratorial features, and checked the mortality and evolution of their renal function until May, 2008. Causes of death were investigated in the \"Programa de Aprimoramento das Informações de Mortalidade\" of São Paulo City and compared with general population of similar age. The survival curve of patients who suffered an acute kidney injury episode was compared with the survival curve of São Paulo population. The evolution of glomerular filtration rate during the first year after hospital discharge was assessed by considering the values of serum creatinine measurements found in outpatients. Results: We included 507 patients who were followed for a median of 21 months. At the end of the study 38% of them had died. The main causes of death were circulatory diseases and neoplasms; a finding similar to São Paulo population. The causes of death were related to the presence of comorbidities before the acute kidney injury. The survival curve of these patients was worse than those of São Paulo population; the factors associated with poor survival were presence of chronic liver failure, Khan index of high risk, admission in medical ward and a new episode of acute kidney injury during the same hospitalization. At hospital discharge, 50% of patients had complete renal recovery, 36% partial renal recovery and 14% had not recovered renal function. The factors associated with complete recovery of renal function were less severe acute kidney injury, presence of presumed chronic kidney disease and need for mechanical ventilation. The study of the evolution of renal function was restricted to 278 patients. These patients showed two types of evolution: those with complete renal recovery were discharged with a glomerular filtration rate greater than the reference, and these values were approached during the first year after discharge. Patients with partial renal recovery and those who did recover renal function at hospital discharge had an improvement in glomerular filtration rate during the first year, without reaching the reference value. Conclusion: Patients with acute kidney injury remain a high mortality after hospital discharge which is related to the presence of comorbidities before hospitalization. Only half of patients had complete renal recovery at hospital discharge, and recovery is associated with reduced severity of acute kidney injury. The lack of information on renal function after discharge occurred in 25% of the included patients. During the first year after hospital discharge the glomerular filtration rate tends to approach to reference values but without reach them.

Abstract:
Background: Aortic stiffness as measured by pulse wave velocity (PWV) is a predictor of cardiovascular disease and other outcomes in different diseased and healthy populations, independent of traditional risk factors. The relationships between PWV measurement, global functional outcome and injury to the brain, kidney, and heart have never been examined in cardiac surgery patients. Objective: The objective of this project was to assess the relationship between aortic stiffness and health related quality of life (QoL), cognitive function, acute kidney injury (AKI), and cardiac function in patients undergoing aortic valve replacement (AVR). Methods: Aortic PWV, QoL, cognitive function, left ventricular (LV) function and NYHA class were assessed pre- and post-operatively (409 ± 159 days). The brain injury biomarker, N-methyl-D-aspartate receptor antibody (NR2Ab), was measured pre-operatively only. The biomarker of myocardial strain, B-type natriuretic peptide (BNP), and the novel AKI biomarker, neutrophil gelatinase-associated lipocalin (NGAL), were measured pre-operatively, and at 3 h and 18-24 h post-CPB. Results: Fifty-six patients (16 females; mean age, 71 ± 8.4 years) were included in this study, of which 50 (89%) patients attended the follow-up visit. No relationship was found between the degree of aortic stenosis (AS) and PWV, and AVR had no effect on aortic stiffness post-operatively. QoL and NYHA class significantly improved, while cognitive function did not deteriorate after AVR. High PWV is independently related to poorer QoL, cognitive function levels and NYHA class both pre- and post-operatively. PWV was not related to LV function, BNP or NGAL levels, but it was independently related to the level of NR2Ab. PWV did not correlate with AKI which was developed in 30% of the cases. Early post-operative plasma level of NGAL is the earliest predictive marker of post-operative AKI and the need for early medical renal intervention. Pre-operative BNP level was significantly and negatively correlated with pre-operative LV function, AS (valve area), and NYHA class in the post-operative follow-up period. Conclusion: In AVR patients, PWV is independently related to global functional status, cognitive function and brain injury biomarkers, but is not related to AKI or myocardial strain.

Abstract:
INTRODUÇÃO: A paratireoidectomia total com auto-enxerto imediato heterotópico (PTH+AE) é uma das técnicas cirúrgicas hoje usadas no tratamento do hiperparatireoidismo secundário à doença renal crônica e do hiperparatireoidismo persistente após o transplante renal. Os níveis adequados de paratormônio sistêmico (PTHs) no pós-operatório ainda são controversos e o perfil funcional do auto-enxerto de tecido paratireóideo, pouco esclarecido. No presente estudo, nós analisamos a função do tecido paratireóideo implantado pacientes com hiperparatireoidismo secundário e terciário. MÉTODO E CASUÍSTICA: Em um estudo prospectivo observacional, 19 pacientes portadores de doença renal crônica (PDRC) e quatro pacientes transplantados renais (PTR) foram submetidos à PTX+AE com e seguidos por um ano. Todos os pacientes apresentaram PTHs indetectável no pós-operatório imediato (POi). Os níveis séricos de PTH em ambos os membros superiores, cálcio, fósforo, fosfatase alcalina e reposição de cálcio elementar e calcitriol foram verificados com um mês, dois, três, quatro, seis, nove e 12 meses após a cirurgia. A 25-Hidroxivitamina D (25OHD) foi medida no POi, seis e 12 meses após a cirurgia. A função do auto-enxerto foi classificada em estados funcionais (EF) de acordo com os níveis de PTHs. RESULTADOS: A maioria dos PDRC e PTR mostraram níveis detectáveis de PTHs já no primeiro mês. No segundo mês pósoperatório, todos os pacientes apresentaram níveis detectáveis de PTHs quando também houve estabilização dos níveis séricos em ambos os grupos. Os gradientes de concentração de PTH não mostraram correlação com o PTHs. No pós-operatório, a hipercalcemia foi observada em 73,7% dos PDRC em pelo menos um episódio, reduzindo ou inibindo a secreção de paratormônio em oito pacientes. Não houve melhora dos níveis de 25OHD em ambos os grupos, permanecendo com níveis insuficientes. Oito PDRC regrediram de EF ao final do estudo. CONCLUSÃO: O perfil funcional do AE é semelhante entre os PDRC e PTR. A função do AE, inicia-se no primeiro mês pós-operatório, atingindo um maior EF até o quarto mês pós-operatório na maioria dos pacientes, porém pode haver declínio da função ao longo do tempo
BACKGROUND: Total parathyroidectomy with immediate forearm transplantation (PTX+AT) is employed in renal hyperparathyroidism. Appropriate postoperative systemic parathyroid hormone (sPTH) levels are still controversial and autograft functional behavior is unclear. In the present study, we analyzed the function of autotransplanted parathyroid tissue in secondary and tertiary hyperparathyroidism. METHODS: In a prospective observational study, 19 dialysis patients (DPs) and 4 kidney transplant patients (KTPs) who underwent PTX+AT were followed. All patients had undetectable PTH in the early postoperative period (ePO). Autograft function and the following biochemical variables were assessed at one, two, three, four, six, nine and 12 months following the operation: serum calcium, phosphorus, alkaline phosphatase, and intact PTH before and after the operation. 25-Hidroxyvitamin D levels (25OHD) were measured in the ePO, six and twelve months. Oral doses of calcium and calcitriol were recorded. Autograft function was stratified into four functional status (FS) according to sPTH. RESULTS: All functioning grafts presented sPTH until the second month. On the second postoperative month, all patients had sPTH detectable levels also when serum levels were steady in both groups. PTH gradients showed no significant correlation with sPTH levels. In at least one occasion in the postoperative period, hypercalcemia was observed in 73.7% of DPs, and it reduced or inhibited PTH secretion in 8 patients. There was no improvement in levels of 25OHD in both groups, resulting in insufficient levels. Eight DPs changed to a lower FS at the end of the study. CONCLUSION: The function of the autotransplanted parathyroid tissue usually initiates during the first month following operation and is similar in patients. The most of the patients reachs FS2 during the fourth month but autograft function can decrease over time

Abstract:
Foi realizado um estudo de farmacocinética da polimixina B em pacientes críticos com desenvolvimento de um modelo populacional. Os critérios de inclusão foram pacientes internados em Unidade de Terapia Intensiva, com idade igual ou superior a 18 anos e em uso de polimixina B intravenosa por um período mínimo de 48 horas. Amostras de sangue, urina e dialisato foram coletadas durante um intervalo de doses no estado de equilíbrio. A concentração de polimixina B no plasma foi medida por meio de cromatografia líquida de alta performance associada à espectrometria de massas acoplada à espectrometria de massas, sua ligação às proteínas plasmáticas foi determinada por meio de diálise de equilíbrio rápido e a fração livre foi calculada. Foram realizadas análise farmacocinética populacional e Simulações de Monte Carlo. Foram incluídos 24 pacientes, dos quais dois estavam em hemodiálise contínua; 54,2% eram do sexo masculino e as medianas da idade, do escore APACHE e do peso corporal total foram de 61,5 anos, 21,5 e 62,5kg, respectivamente. As doses de polimixina B, conforme prescrição do médico assistente, variaram entre 0,45-3,38mg/kg/dia. O clearance estimado da creatinina nos 22 pacientes sem hemodiálise variou entre 10-143mL/min. A mediana da fração livre plasmática da polimixina B foi de 0,42 e a média (± desvio padrão) da fração livre da área sob a curva ao longo de um dia (fAUC0-24h) da polimixina B foi de 29,2±12,0mg•h/L, incluindo os pacientes em hemodiálise. A polimixina B foi excretada predominantemente por vias não renais e as medianas de sua recuperação urinária de forma inalterada foi de 4,04% e do seu clearance renal foi de 0,061L/hora. Nos pacientes 1 e 2 em hemodiálise foram identificados, respectivamente, clearance corporal total de 0,043 e 0,027L/h/kg, clearance da hemodiálise de 0,0052 e 0,0015L/h/kg; no dialisato foram recuperados 12,2% e 5,62% da dose como polimixina B não modificada. O clearance corporal total da polimixina B não mostrou nenhuma relação com o clearance da creatinina, escore APACHE II ou idade. A disposição da polimixina B no tempo foi adequadamente descrita pelo modelo de dois compartimentos com eliminação linear. O modelo farmacocinético populacional proporcionou ajustes excelentes para os perfis observados de concentração-tempo para pacientes individuais e as concentrações individuais e populacionais ajustadas foram precisas. O ajuste dos clearances e dos volumes de distribuição para o peso corporal total reduziu a variabilidade intersujeitos em 3,4% para o clearance e 41,7% para o volume de distribuição central; nos pacientes em diálise, após esse ajuste, os parâmetros estimados se assemelharam aos dos demais pacientes. As Simulações de Monte Carlo foram feitas com seis diferentes regimes de doses clinicamente relevantes escalonados pelo peso corporal total. O regime de doses de 1,5mg/kg 12/12h forneceu uma AUC0-24h de polimixina B no dia 4 de 90.4mg•hora/L para 50% dos pacientes, adequada para erradicação bacteriana em infecções graves por Pseudomonas aeruginosa ou Acinetobacter baumannii com concentração inibitória mínima para a polimixina B ≤2mg/L. Nas Simulações de Monte Carlo também foi possível identificar que uma melhor área sob a curva só foi atingida no dia 4 de tratamento. Este estudo mostrou que a dose de polimixina B intravenosa deve ser ajustada ao peso corporal total, que o melhor regime de doses é o de 1,5mg/kg 12/12h precedido de dose de ataque de 2,5mg/kg e que não há indicação de ajuste para a função renal, mesmo em pacientes em hemodiálise contínua.
A polymyxin B pharmacokinetics study in critically ill patients was conducted with the development of a population modeling. The inclusion criteria were patients from Intensive Care Unit, aged ≥18 years who received intravenous polymyxin B for ≥ 48 hours. Blood, urine and dialysate samples were collected over a dosing interval at steady state. Polymyxin B concentrations was measured by liquid chromatography- tandem mass spectrometry, its plasma protein binding was determined by rapid equilibrium dialysis and unbound fraction was calculated. Population pharmacokinetic analysis and Monte Carlo Simulations were conducted. Twenty four patients were enrolled, two of whom on continuous hemodialysis; 54.2% were male; the median of age, APACHE II score and total body weight were 61.5years, 21.5 and 62.5kg, respectively. The physician-selected dose of polymyxin B was 0.45- 3.38mg/kg/day. The creatinine clearance of the 22 patients without hemodialysis ranged from 10 to 143mL/min. The median unbound fraction in plasma of polymyxin B was 0.42 and the mean (± standard deviation) of the area under the curve over a day for unbound (fAUC0-24h) polymyxin B was 29.2±12.0mg•hour/L, including hemodialysis patients. Polymyxin B was predominantly nonrenally cleared with median unchanged urinary recovered of 4.04%; the median renal clearance was 0.061L/hour. Patients 1 and 2 in hemodialysis presented, respectively, total body clearance of 0.043 and 0.027L/h/kg, hemodialysis clearance of 0.0052 and 0.0015L/h/kg; 12.2% and 5.62% of the polymyxin dose were recovered intact in the dialysate. Polymyxin B total body clearance did not show any relationship with creatinine clearance, APACHE II score, or age. The time course of polymyxin B concentrations was well described by a 2-compartment disposition model with linear elimination. The population pharmacokinetics model provided excellent fits to the observed concentration-time profiles for individual patients and the individual-fitted and population-fitted concentrations were adequately precise. Linear scaling of clearances and volumes of distribution by total body weight reduced the between subject variability in 3.4% for clearance and 41.7% for the central volume of distribution; after this scaling, the estimated parameters in hemodialysis patients were within the range of estimates from the other patients. The population mean of the total body clearance of polymyxin B when scaled by total body weight (0.0276L/hour/kg) showed remarkably low interindividual variability. The Monte Carlo Simulations were performed for six different clinically relevant dosage regimens scaled by total body weight. The regimen of 1.5mg/kg/12 hours provided an AUC0- 24h of polymyxin B of 90.4 mg•h/L in day 4 for 50% of patients which is appropriate considering severe infections by Pseudomonas aeruginosa or Acinetobacter baumannii with minimal inhibitory concentration for polymyxin B ≤2mg/L. In Monte Carlo Simulations we also identified that the best area under the curve was attained only in the day 4 of the treatment. This study showed that doses of intravenous polymyxin B are best scaled by total body weight, that the best regimen of doses is 3mg/kg/day with a loading dose of 2.5mg/kg and that its dosage selection should not be based on renal function, even in patients in continuous hemodialysis.

Abstract:
L'insuffisance rénale aiguë (IRA) sévère représente un enjeu médical crucial en réanimation en raison de sa fréquence et de sa morbimortalité élevée. Malgré les progrès en techniques d'épuration extrarénale (EER) et en soins intensifs, la prise en charge des patients atteints d'IRA demeure complexe. Dans ce contexte, l'identification des signes de récupération rénale et la compréhension des mécanismes sous-jacents sont cruciales pour améliorer les perspectives cliniques des patients atteints de cette affection. Ce travail est divisé en trois volets, chacun centré sur un aspect et une temporalité spécifique de la récupération rénale. La première partie visait à évaluer l'utilité d'un panel de biomarqueurs urinaires et plasmatiques (CCL14, KIM1, DPP3, PenKid, Nicotinamide, M2PY et MNM) pour prédire la nécessité d'initier une séance d'EER en réanimation dans les 72 heures suivant l'apparition d'une IRA sévère. Il s'agit d'une étude ancillaire de l'étude AKIKI 2, pour laquelle une biobanque de prélèvements sanguins et urinaires était disponible. Nous avons établi un critère de jugement principal objectif et reproductible, fondé sur des données récentes de la littérature, considérant la nécessité comme liée aux critères suivants : oligo-anurie de plus de 72 heures, urée supérieure à 40 mmol/L et conditions mettant en jeu le pronostic vital immédiat (œdème aigu du poumon réfractaire aux diurétiques, acidose métabolique profonde et hyperkaliémie menaçante). Nous n’avons pas été en mesure de démontrer une utilité de ce panel dans ce contexte, quelle que soit la sous-population de patients, ses performances étant inférieures ou égales à celles de marqueurs couramment dosés comme la créatininémie. La deuxième partie s'est concentrée sur la prédiction du succès du sevrage de l'EER. Nous avons fusionné les cohortes AKIKI et AKIKI 2 (patients ayant connu un épisode d'IRA sévère en réanimation) et sélectionné les patients traités selon une stratégie dite d'attente (critères précédemment définis et qui tendent à faire consensus) pour qui un sevrage de l'EER a été tenté. Un échec a été défini comme une nouvelle session d'EER ou un décès dans les sept jours suivant la tentative. L'analyse multivariée a identifié le choc septique à l'admission, la diurèse et les catécholamines le premier jour de la tentative, ainsi que la durée de l'EER comme facteurs prédictifs du succès. À partir de ces résultats, nous avons élaboré un score, l'UNDERSCORE (UNplugging a Dialysis catheter in the context of an Endgame RRT process), pour aider le clinicien à envisager le sevrage de l'EER. Ce score sera validé prospectivement dans le cadre de l'étude ICRAKI à venir, centrée sur les modalités d'EER en réanimation. Enfin, la dernière partie a consisté en un suivi prospectif des patients inclus dans l'étude AKIKI afin d'évaluer la survie, la fonction rénale et la qualité de vie à long terme d'une population ayant fait un épisode d'IRA sévère en réanimation. La médiane de suivi a été de 3,35 années après l'épisode. Dans cette population grevée d'une forte mortalité à 60 jours, il a été observé chez 20% des survivants une dégradation de la fonction rénale à 4 ans
Severe Acute Kidney Injury (AKI) represents a critical medical challenge in intensive care units (ICU) due to its frequency and high morbidity and mortality. Despite advancements in Renal Replacement Therayp (RRT) techniques and intensive care, the management of patients with AKI remains complex. In this context, identifying signs of renal recovery and understanding the underlying mechanisms are crucial for improving the clinical outcomes of patients suffering from this condition. This work is divided into three sections, each focusing on a specific aspect and timeframe of renal recovery. The first section aimed to evaluate the utility of a panel of urinary and plasma biomarkers (CCL14, KIM1, DPP3, PenKid, Nicotinamide, M2PY, and MNM) to predict the need to initiate RRT in ICU within 72 hours following the onset of severe AKI. This is an ancillary study of the AKIKI 2 study, for which a biobank of blood and urine samples was available. We established a primary objective and reproducible endpoint based on recent literature, considering the necessity as one of the following criteria: oligo-anuria for more than 72 hours, urea levels above 40 mmol/L, and conditions that are immediately life-threatening (acute pulmonary edema unresponsive to diuretics, profound metabolic acidosis, and life-threatening hyperkalemia). This panel did not prove to be useful in this context, regardless of the patient subpopulation, with performances equal to or less than commonly measured markers like creatinine levels. The second section focused on predicting successful weaning from RRT. We merged the AKIKI and AKIKI 2 cohorts (patients who experienced an episode of severe AKI in ICU) and selected patients treated with a "standard deleyed" strategy (previously defined criteria that are starting to gain consensus) for whom weaning from RRT was attempted. Failure was defined as a new RRT session or death within seven days following the attempt. Multivariate analysis identified septic shock upon admission, urine output and catecholamine levels on the first day of the attempt, as well as the duration of RRT, as predictive factors of success. Based on these findings, we developed a score, the UNDERSCORE (UNplugging a Dialysis catheter in the context of an Endgame RRT process), to assist clinicians in considering weaning from RRT. This score will be prospectively validated in the context of the upcoming ICRAKI study, focusing on RRT modalities in ICU. Finally, the last section consisted in a prospective follow-up of patients included in the AKIKI study to evaluate the long-term survival, renal function, and quality of life in a population that experienced an episode of severe AKI in ICU. The median follow-up was 3.35 years after the episode. In this population burdened by high mortality at D60, a decline in renal function was observed in 20% of survivors at 4 years

Abstract:
Specularity is a very common phenomenon in the real world and confounds many computer vision tasks such as stereo. The first purpose of this thesis is to design a real-time algorithm of specularity detection. After that, with the knowledge of where the specularities are, a stereo correspondence approach robust to specularity is proposed. Finally, a specularity recovery method is presented to recover the underlying diffuse color using the stereo correspondence information. For real-time specularity detection, a new concept of unnormalized Wiener entropy (UW Entropy) is first proposed in this thesis, which has the desirably simple final form and requires no information about the lighting condition, surface structure, imaging process, pre-segmentation, polarization state, and so forth. However, like other specularity detection methods based on color alone, some false positives may be detected. To distinguish between genuine specularities and false positives, a Support Vector Machine is learned in the proposed SpecLBP space as well as three other spaces as comparisons. An alternative version is also presented for the beam-splitter based stereo pairs in the 3D movie industry, where the curse of side-effect of the beamsplitter is turned into a blessing for identifying problematic specularities. After the genuine specularities are spotted, a new specularity-invariant stereo correspondence method is proposed. By constructing an UW Entropy based matching energy and minimizing it in the MAP-MRF framework using graph cuts, a disparity map robust to specularities can be gained, which offers a precious piece of information for specularity recovery in the ending part of this thesis. Experiment results show our methodology's efficacy in real-time specularity detection, specularity-invariant stereo correspondence, as well as specularity recovery and demonstrate our methodolodgy's great potential for the 3D movie industry. By comparing the performance of the proposed SpecLBP code and three other LBP variants, the SpecLBP code's better performance justifies our claim that the best texture code is task specific, not the one that captures the most information.
La réflexion spéculaire est un phénomène fréquemment observé dans la nature. Et pourtant, ce type de réflexion pose encore problème à plusieurs algorithmes de vision artificielle telle que l'interprétation de l'imagerie stéréoscopique. Cette thèse a pour premier objectif de concevoir un algorithme temps réel capable de détecter les réflexions spéculaires. Par la suite, connaissant l'endroit où apparait ce phénomène dans l'image, une approche pour la correspondance stéréoscopique robuste aux réflexions spéculaires est proposée. Et enfin, une méthode de récupération de la couleur diffuse sous-jacente aux réflexions est présentée, en tirant profit de l'information acquise par la correspondance stéréo. Pour effectuer la détection des réflexions spéculaires en temps réel, un nouveau concept d'entropie de Weiner non normalisée (entropie UW) est d'abord proposé par cette thèse. L'entropie UW est caractérisée par une formulation analytique simple qui ne requière aucune information supplémentaire sur les conditions d'éclairage, la structure de la surface, la prise d'image, l'état de polarisation de la lumière, aucune présegmentation et ainsi de suite. Cependant, comme d'autres méthodes de détection des réflexions spéculaires basées seulement sur la couleur, de faux positifs peuvent être obtenus. Pour faire la distinction entre les réflexions spéculaires véritables et les faux positifs, un séparateur à vaste marge (SVM) est entrainé dans l'espace « SpecLBP » proposé, et également dans trois autres espaces de la littérature, à titre de comparaison. Une adaptation du système est également présentée pour traiter les paires d'images stéréo obtenues à l'aide d'un miroir semi-argenté, tel qu'utilisé dans l'industrie du film 3D, où les effets indésirables du miroir deviennent plutôt d'une aide précieuse pour localiser les réflexions problématiques. Pour faire suite à la détection des réflexions authentiques, une nouvelle méthode de correspondance stéréo robuste aux réflexions est proposée. En formulant l'entropie UW sous forme d'énergie, et en minimisant cette énergie dans le cadre d'un PAM-MRF (résolu en utilisant des coupes de graphes), une carte de disparité stéréoscopique robuste aux réflexions peut être acquise. Cette évaluation de la disparité en présence des réflexions est une information précieuse pour la récupération de la couleur qui est présentée dans la dernière partie de cette thèse.Les résultats expérimentaux obtenus démontrent l'efficacité des méthodes proposées pour la détection des réflexions spéculaires en temps réel, pour la correspondance stéréo en présence de réflexions, ainsi que pour la récupération de la couleur sous-jacente aux réflexions. Les expérimentations permettent également de démontrer le potentiel de cette méthode pour l'industrie du cinéma 3D. En comparant la performance de la représentation « SpecLBP » proposée et les trois autres variantes de LBP, la performance supérieure du code « SpecLBP » valide notre hypothèse selon laquelle une représentation de la texture est meilleure, lorsqu'adaptée à une tâche spécifique, et non lorsqu'elle capture un maximum d'informations.

Abstract:

Recovery is a fundamental service in database systems. In this work, we present a new mechanism for diskless real-time recovery in fully replicated distributed real-time database systems. Traditionally, recovery has relied on disk-resident redundant data. Unfortunately, disks cannot always be used in real-time systems since these systems are sometimes used in environments which do not allow the use of disks. Also, minimizing the amount of hardware can save money, especially in mass-produced products. Instead of loading the database from disk, our recovery mechanism enables a restarted node to retrieve a copy of the database from an arbitrary remote node. The recovery mechanism does not violate timeliness during normal processing and, during recovery, all nodes except for the recovering node can guarantee the timeliness of critical transactions. The mechanism uses fuzzy checkpointing to copy the database to the recovering node. Fuzzy checkpointing has been chosen since it copies the database without regard to concurrency control and, thus, does not increase data contention in the database. We conclude that the suggested recovery mechanism is a feasible option for fully replicated distributed real-time database systems.

Abstract:
The Inland Empire -Riverside and San Bernardino Counties - was one of the hardest hit areas in all of the United States during the Great Recession. Home prices have declined over 50%, significantly more than the 25% decline in the surrounding Los Angeles County, and housing starts have declined to over 90% from 2005. The Inland Empire has one of the highest unemployment rates in the US at 14.8%. This paper attempts to forecast the recovery for the Inland Empire. Employing univariate forecasts along with VAR(12) forecasts, focusing on housing starts and unemployment rates as the underlying variables, we find that there is little hope for a recovery over the next 3 years. The model predicts unemployment to either rise even more or, at best, remain stagnant. Housing starts are predicted to remain constant over the next three years.

Abstract:

In this dissertation, we consider the problem of recovering a crashed node in a distributed database. We especially focus on real-time recovery in eventually consistent databases, where the consistency of replicated data is traded off for increased predictability, availability and performance. To achieve this focus, we consider consistency preservation techniques as well as recovery mechanisms.

Our approach is to perform a thorough literature survey of these two fields. The literature survey considers not only recovery in real-time, distributed, eventually consistent databases, but also related techniques, such as recovery in main-memory resident or immediately consistent databases. We also examine different techniques for consistency preservation.

Based on this literature survey, we present a taxonomy and state-of-the-art report on recovery mechanisms and consistency preservation techniques. We contrast different recovery mechanisms, and highlight properties and aspects of these that make them more or less suitable for use in an eventually consistent database. We also identify unexplored areas and uninvestigated problems within the fields of database recovery and consistency preservation. We find that research on real-time recovery in distributed databases is lacking, and we also propose further investigation of how the choice of consistency preservation technique affects (or should affect) the design of a recovery mechanism for the system.

Abstract:
AbstractThe water proton longitudinal relaxation time, T1, is a common and useful MR parameter in nephrology research. Here we provide three step-by-step T1-mapping protocols suitable for different types of nephrology research. Firstly, we provide a single-slice 2D saturation recovery protocol suitable for studies of global pathology, where whole-kidney coverage is unnecessary. Secondly, we provide an inversion recovery type imaging protocol that may be optimized for specific kidney disease applications. Finally, we also provide imaging protocol for small animal kidney imaging in a clinical scanner.This chapter is based upon work from the COST Action PARENCHIMA, a community-driven network funded by the European Cooperation in Science and Technology (COST) program of the European Union, which aims to improve the reproducibility and standardization of renal MRI biomarkers. This analysis protocol chapter is complemented by two separate chapters describing the basic concept and experimental procedure.

Abstract:
The field of continuum robotics continues to advance rapidly, giving these manipulators potential to change the paradigm of minimally invasive medical surgery (MIS) in a near future. As MIS techniques are refined to improve recovery and cosmesis and reduce invasiveness and co-morbidity, continuum robot requirements in MIS applications have become ever stricter. One such application is Percutaneous Nephrolithotomy (PCNL), a first-choice minimally invasive urological procedure for the extraction of large renal calculi (kidney stones) > 2 cm. The standard of care in PCNL entails the percutaneous insertion of a nephroscope via a small incision in the lumbar or lateral abdominal wall regions, followed by accessing a renal calyx to allow direct manipulation of the stone using specialized lithotripsy devices such as ultrasonic or laser equipment, which aids in reducing blood loss during survery [1]. This study proposes a lightweight, compact handheld Concentric Tube Robot (CTR) as an alternative to the conventional straight and rigid PCNL tools. Unlike Girerd et al. [2] our design was conceived solely for the use in PCNL. Our envisaged device aims to provide an alternative to the conventional rigid nephroscopes by flexibly maneuvering the handheld CTR through a prescribed renal calyx and reaching clinical targets while safeguarding sensitive anatomical structures, as illustrated in Fig. 1. Additionally, it is designed to deliver an energy source through its lumen to the renal calculi for laser ablation.

Abstract:
Chloramphenicol is an important antibiotic commonly used in undeveloped as well as developing nations in treatment of life-threatening bacterial infections. However,renal-toxicity is resulted by chloramphenicol at a high concentration Sabaet.al., [20].It is studied that the damaged in kidney caused due to the free radicals generated in the kidney and other body organs also. Theeffect of Millingtoniahortensis Linn. Extractwas examined by estimating the elements, such as, nitrogen, glutathione, serum creatinine, lipid peroxidation and the things like catalase along with SOD activities. In present research, nephrotoxicity is induced by chloramphenicol that ischaracterizedby significant increment of serum markers levels,for that LPO level raised andSOD level reduced along withGSH and CAT levels. Co-signification of methanolic extract with chloramphenicol was designed for significantly prevent both the functional and histological renal injury protection. It is concluded that the phytogenic antioxidants play an important significance in the ameliorating action for recovery of damaging effects caused by the Chloromycetin.

Abstract:
The report shows that wages and the purchasing power of households have been dented considerably during the past three years, first by the COVID-19 pandemic and then, as the world economy started to recover from that crisis, by the global rise in inflation. Available evidence for 2022 suggests that rising inflation is causing real wage growth to dip into negative figures in many countries, reducing the purchasing power of the middle class and hitting low-income groups particularly hard. This cost-ofliving crisis comes on top of significant losses in the total wage bill for workers and their families during the COVID-19 crisis, which in many countries had the greatest impact on low-income groups. In the absence of adequate policy responses, the near future could see a sharp erosion of the real incomes of workers and their families and an increase in inequality, threatening the economic recovery and possibly fuelling further social unrest.

Abstract:
The Caribbean Region Quarterly Bulletin provides economic conjunctural and structural information about this particular region. This issue highlights the real growth that remained weak during the first half of 2013 in The Bahamas, Barbados and Jamaica. On the other hand, Guyana and Suriname are expected to outperform the region with an average growth rate of 5% in 2013. There are some signs of recovery in Trinidad and Tobago, however, growth in the energy sector has not taken off yet.
