The coexistence of diabetic retinopathy and diabetic nephropathy is associated with worse kidney outcomes.

Background: Up to 50-60% of patients with diabetes have non-diabetic kidney disease (NDKD) on kidney biopsy. Diabetic retinopathy (DR) is a microvascular complication of diabetes frequently associated with diabetic nephropathy (DN). The objective of the current study was to investigate the kidney outcomes and survival in patients with biopsy diagnoses of DN and NDKD according to the presence of DR. Methods: We conducted an observational, multicentre and retrospective study of the pathological findings of renal biopsies from 832 consecutive patients with diabetes from 2002 to 2014 from 18 nephrology departments. The association of DR with kidney replacement therapy (KRT) or survival was assessed by Kaplan-Meier and Cox regression analyses. Results: Of 832 patients with diabetes and renal biopsy, 768 had a retinal examination and 221/768 (22.6%) had DR. During a follow-up of 10 years, 288/760 (37.9%) patients with follow-up data needed KRT and 157/760 (20.7%) died. The incidence of KRT was higher among patients with DN (alone or with NDKD) and DR [103/175 (58.9%)] than among patients without DR [88/216 (40.7%), P < .0001]. The incidence of KRT was also higher among patients with only NDKD and DR than among those without DR [18/46 (39.1%) versus 79/331 (23.9%), P < .0001]. In multivariate analysis, DR or DN were independent risk factors for KRT {hazard ratio [HR] 2.48 [confidence interval (CI) 1.85-3.31], P < .001}. DN (with or without DR) was also identified as an independent risk factor for mortality [HR 1.81 (CI 1.26-2.62), P = .001]. Conclusions: DR is associated with a higher risk of progression to kidney failure in patients with histological DN and in patients with NDKD.

Risk factors for non-diabetic renal disease in diabetic patients.

BACKGROUND: Diabetic patients with kidney disease have a high prevalence of non-diabetic renal disease (NDRD). Renal and patient survival regarding the diagnosis of diabetic nephropathy (DN) or NDRD have not been widely studied. The aim of our study is to evaluate the prevalence of NDRD in patients with diabetes and to determine the capacity of clinical and analytical data in the prediction of NDRD. In addition, we will study renal and patient prognosis according to the renal biopsy findings in patients with diabetes. METHODS: Retrospective multicentre observational study of renal biopsies performed in patients with diabetes from 2002 to 2014. RESULTS: In total, 832 patients were included: 621 men (74.6%), mean age of 61.7 ± 12.8 years, creatinine was 2.8 ± 2.2 mg/dL and proteinuria 2.7 (interquartile range: 1.2-5.4) g/24 h. About 39.5% (n = 329) of patients had DN, 49.6% (n = 413) NDRD and 10.8% (n = 90) mixed forms. The most frequent NDRD was nephroangiosclerosis (NAS) (n = 87, 9.3%). In the multivariate logistic regression analysis, older age [odds ratio (OR) = 1.03, 95% CI: 1.02-1.05, P < 0.001], microhaematuria (OR = 1.51, 95% CI: 1.03-2.21, P = 0.033) and absence of diabetic retinopathy (DR) (OR = 0.28, 95% CI: 0.19-0.42, P < 0.001) were independently associated with NDRD. Kaplan-Meier analysis showed that patients with DN or mixed forms presented worse renal prognosis than NDRD (P < 0.001) and higher mortality (P = 0.029). In multivariate Cox analyses, older age (P < 0.001), higher serum creatinine (P < 0.001), higher proteinuria (P < 0.001), DR (P = 0.007) and DN (P < 0.001) were independent risk factors for renal replacement therapy. In addition, older age (P < 0.001), peripheral vascular disease (P = 0.002), higher creatinine (P = 0.01) and DN (P = 0.015) were independent risk factors for mortality. CONCLUSIONS: The most frequent cause of NDRD is NAS. Elderly patients with microhaematuria and the absence of DR are the ones at risk for NDRD. Patients with DN presented worse renal prognosis and higher mortality than those with NDRD. These results suggest that in some patients with diabetes, kidney biopsy may be useful for an accurate renal diagnosis and subsequently treatment and prognosis.

Dexmedetomidine for Improved Quality of Emergence From General Anesthesia: A Dose-Finding Study.

BACKGROUND: Dexmedetomidine provides smooth and hemodynamically stable emergence at the expense of hypotension, delayed recovery, and sedation. We investigated the optimal dose of dexmedetomidine for prevention of cough, agitation, hypertension, tachycardia, and shivering, with minimal side effects. METHODS: In this prospective, randomized, double-blind trial, 216 adult patients were randomly assigned to dexmedetomidine 1 µg/kg (D 1), 0.5 µg/kg (D 0.5), 0.25 µg/kg (D 0.25), or control (C). During emergence, cough, agitation, hemodynamic parameters, shivering, time to extubation, and sedation scores were recorded. RESULTS: A total of 190 patients were analyzed. The respective incidences for the groups D 1, D 0.5, and D 0.25 versus group C were 48%, 64%, and 64% vs 84% for cough-corrected P < .003 between groups D 1 and C; 33%, 34%, and 33% vs 72% for agitation-corrected P < .003 between group C and each of the study groups; and 4%, 2%, and 7% vs 22% for shivering-corrected P = .03 and corrected P = .009 between groups D 1 and D 0.5 versus group C, respectively. The percent increase from baseline blood pressure on extubation for the 3 treatment groups was significantly lower than group C. Percent increase in heart rate was lower than control in groups D 1 and D 0.5 but not in group D 0.25. Time to extubation and sedation scores were comparable. However, more hypotension was recorded during the emergence phase in the 3 treatment groups versus group C. CONCLUSIONS: D 1 at the end of surgery provides the best quality of emergence from general anesthesia including the control of cough, agitation, hypertension, tachycardia, and shivering. D 0.5 also controls emergence phenomena but is less effective in controlling cough. The 3 doses do not delay extubation. However, they cause dose-dependent hypotension.

Diagnosis and laparoscopic management of retrocaval ureter: A review of the literature and our case series.

OBJECTIVES: To expose the diagnosis and the different laparoscopic approaches for the surgical management of patients with retrocaval ureter (RCU) and to share our experience on two cases. METHODS: Updated literature review on Pubmed and debating personal experiences including ours (double j stent insertion before the surgery, use of 4 trocards, transperitoneal approach, pyelopyelostomy for the anastomosis…), concerning the laparoscopic treatment of the RCU. RESULTS: Laparoscopic treatment of RCU is a recommended management for many reasons: less blood loss during the surgery, a shorter hospital stay, less postoperative pain and superior esthetic results with excellent functional results. All of these findings were also a part of our experience on the two reported cases: operative time was 210 and 180 min with no significant bleeding, hospital stay was 48 h post operatively for both patients that were symptom free with no renal dilation after 2 years of close follow up. The main cause of the increased operating time is the intracorporeal anastomosis of the ureter which remains the main limiting factor of the laparoscopic surgery. CONCLUSIONS: The literature review has clearly shown the advantages of minimally invasive techniques for the treatment of retrocaval ureter. Pure laparoscopic treatment (as in our two cases), seems feasible and technically reliable, and should be the standard surgical option for the treatment of RCU.

Bilateral laparoscopic ureterolysis using hydrodissection in retroperitoneal fibrosis: a new application of an old technique.

Objective: To describe our new laparoscopic approach in ureterolysis using the ERBEJET® 2 device to hydrodissect the ureters in idiopathic retroperitoneal fibrosis. Methods: Bilateral laparoscopic ureterolysis was done after medical therapy failure (steroids) in a 47 year old patient with retroperitoneal fibrosis. Ureteral stents were placed before surgery. Only five trocars were used for both sides, Toldt's fascia was opened and the dissection was performed till the psoas muscle. The ureters were completely freed from the fibrotic tissue using the ERBEJET 2 device (pure hydrodissection). An omental wrap was passed behind the colonic flexure at the right and placed around the ureter. At the left, we closed Toldt's fascia by running sutures back to the freed ureter. Results: The operating time was 198 mins. The blood loss was 50 cc. The hospital stay was 3 days. The double J stents were removed at 4 weeks postoperatively. After 2 years, the patient is free of symptoms with normal creatinine level and no urinary tract obstructions. Conclusions: Hydrodissection of the ureter in retroperitoneal fibrosis is a new application in the upper urinary tract laparoscopic approach that has not been described in literature before. It seems to offer excellent midterm outcomes. The use of ERBEJET 2 device seems to simplify the procedure and make it feasible and safe (less trauma to the ureter and more conservation of its blood supply). We believe that comparative studies are needed to assess the role of hydrodissection in ureterolysis for retroperitoneal fibrosis.

Arteriovenous fistulae after renal biopsy: diagnosis and outcomes using Doppler ultrasound assessment.

BACKGROUND: Percutaneous renal biopsy (PRB) is an important technique providing relevant information to guide diagnosis and treatment in renal disease. As an invasive procedure it has complications. Most studies up to date have analysed complications related to bleeding. We report the largest single-center experience on routine Doppler ultrasound (US) assessment post PRB, showing incidence and natural history of arteriovenous fistulae (AVF) post PRB. METHODS: We retrospectively analysed 327 consecutive adult PRB performed at Ramon Cajal University Hospital between January 2011 and December 2014. All biopsies were done under real-time US guidance by a trained nephrologist. Routine Doppler mapping and kidney US was done within 24 h post biopsy regardless of symptoms. Comorbidities, full blood count, clotting, bleeding time and blood pressure were recorded at the time of biopsy. Post biopsy protocol included vitals and urine void checked visually for haematuria. Logistic regression was used to investigate links between AVF, needle size, correcting for potential confounding variables. RESULTS: 46,5% were kidney transplants and 53,5% were native biopsies. Diagnostic material was obtained in 90,5% (142 grafts and 154 native). Forty-seven AVF's (14.37%) were identified with routine kidney Doppler mapping, 95% asymptomatic (n = 45), 28 in grafts (18.4%) and 17 natives (9.7%) (p-value 0.7). Both groups were comparable in terms of comorbidities, passes, cylinders or biopsy yield (p-value NS). 80% were <1 cm in size and 46.6% closed spontaneously in less than 30 days (range 3-151). Larger AVF's (1-2 cm) took a mean of 52 days to closure (range 13-151). Needle size was not statistically significant factor for AVF (p-value 0.71). CONCLUSIONS: Contrary to historical data published, AVF's are a common complication post PRB that can be easily missed. Routine US Doppler mapping performed by trained staff is a cost-effective, non-invasive tool to diagnose and follow up AVF's, helping to assess management.

Women victims of domestic violence: a phenomenological approach / Mujeres víctimas de violencia doméstica: un enfoque fenomenológico / Mulheres vítimas de violência doméstica: uma abordagem fenomenológica

The aim of this study was to understand the experiences of women victims of domestic violence. The study entailed phenomenological research based on the theoretical framework of Maurice Merleau-Ponty, developed with ten women who were victims of domestic violence treated at a women's healthcare center in a municipality in the interior of the Brazilian state of São Paulo. Nuclei of meanings emerged from the statements, based on the analysis of the phenomenon of violence from the interviews, and led to the following themes: living with fear; living with physical injuries; and the decision to file a report after the violence experienced. The results showed that the experience lived and contained in these women's bodies enabled each one of them to evaluate their own existence, arousing the desire to leave the situation in order to exercise their role in the world. Thus, their bodies instrumentalized their beings, and allowed them to break the cycle of domestic violence.

Este estudio tuvo como objetivo comprender la experiencia de las mujeres víctimas de la violencia doméstica. La investigación fenomenológica, fundamentado en el marco de Maurice Merleau-Ponty, desarrollado con diez mujeres víctimas de violencia doméstica atendidas en un Centro de Referencia para la Asistencia a la Mujer en la ciudad de São Paulo, Brasil. A partir del análisis del fenómeno de la violencia derivada de las entrevistas, surgieron de los relatos núcleos de significados que originaron los siguientes temas: Cómo vivir con el miedo, la convivencia con lesiones físicas y la decisión de delatar después de la violencia todo lo que sufren. Los resultados mostraron que la experiencia y el contenido en el cuerpo de estas mujeres les permite una revisión de su propia existencia, despertando el deseo de salir de esetormento para desempeñar su papel en el mundo. Por lo tanto, su cuerpo y su ser se instrumentalizaron y permitiócon esto romper el ciclo de La violencia doméstica experimentada por estas mujeres.
