Acquired thrombotic thrombocytopenic purpura (TTP) is an autoimmune disease that can be triggered by different events, including viral infections. It presents as thrombotic microangiopathy and can lead to severe complications that often require management in the intensive care unit (ICU).  https://www.selleckchem.com/products/Camptothecine.html  We report a patient who presented with acquired TTP following COVID-19 infection. A 44-year-old woman presented to the emergency department with severe anemia, acute kidney injury and respiratory failure due to COVID-19. Clinical and laboratory findings were suggestive for thrombotic microangiopathy. On day 8 laboratory tests confirmed the diagnosis of acquired TTP. The patient needed 14 plasma exchanges, treatment with steroids, rituximab and caplacizumab and 18 days of mechanical ventilation. She completely recovered and was discharged home on day 51. Acquired TTP can be triggered by different events leading to immune stimulation. COVID-19 has been associated with different inflammatory and auto-immune diseases. Considering the temporal sequence and the lack of other possible causes, we suggest that COVID-19 infection could have been the triggering factor in the development of TTP. Since other similar cases have already been described, possible association between COVID and TTP deserves further investigation.
  The older population has increased sharply in China. However, renal clinical and histopathological data in this population are lacking. This study investigated the clinicopathologic features and the related risk factors for long-term renal survival in older patients with diabetic nephropathy (DN).
 
  In this retrospective observational study, 74 older patients (≥ 60years old) with type 2 diabetes mellitus and biopsy-proven DN from 2007 to 2019 were included. Clinical data were extracted from electronic records. Renal biopsy specimens were semiquantitatively evaluated using the Renal Pathology Society (RPS) classification system. Cox proportional hazard analysis was used to estimate hazard ratios (HRs) for progression to end-stage renal disease (ESRD).
 
  During the median follow-up period of 22months, 24 (32%) older patients progressed to ESRD. Older patients who progressed to ESRD had poorer renal function, lower hemoglobin and albumin concentrations, more severe glomerular lesions, and higher percentages of Kimmelstiel-Wilson lesions than those who did not progress to ESRD. After adjusting for age, sex, baseline renal function, and pathological parameters, multivariate Cox proportional hazard analysis showed that RPS glomerular classification (HR 2.49, 95% confidence interval [CI] 1.03-6.04), estimated glomerular filtration rate (eGFR) (HR 0.76, 95% CI 0.58-0.99), and proteinuria (HR 3.85, 95% CI 1.44-10.27) were independent risk factors for progression to ESRD.
 
  Lower eGFR, heavier proteinuria, and more severe RPS glomerular lesions were associated with ESRD in older patients with type 2 diabetes mellitus and DN.

  Chronic kidney disease is associated with an increased risk of vascular events and bone fractures, and its prevalence is increasing. Despite the high frequency of strokes and bone fractures in the hemodialysis (HD)population, the few studies on rehabilitation outcomes in this population are controversial. The current study assessed the efficacy of inpatient rehabilitation for hemodialysis patients.
 
  This is a retrospective, observational review of medical records of all chronic HD patients who underwent rehabilitation in Meir Medical Center, from 2008 to 2018. The primary endpoint was functional independence measure (FIM) score at discharge. Secondary endpoints were all-cause mortality, efficiency of rehabilitation and discharge destination from rehabilitation.
 
  During the study period, 162 patients were included in the analysis. 76/81 (93.8%) hemodialysis patients had improvement FIM scores. There were no significant differences in FIM scores at discharge between hemodialysis patients and controls. However, the efficiency of rehabilitation expressed by FIM efficiency (progress measured as FIM gain/length of stay in rehabilitation) was higher in hemodialysis vs. controls. 73% of hemodialysis patients were discharged home. There was no significant difference in discharge destinations between groups. Both 30-day and 1-year mortality after admission to rehabilitation was higher in HD vs. controls (OR 4.97, 95% CI 1.4-18.2, p = 0.008 and OR 4.98, 95% CI 1.8-14.1, p value = 0.001, respectively).
 
  Hemodialysis patients may benefit from inpatient rehabilitation. Although mortality was higher, efficacy of rehabilitation for hemodialysis patients is comparable to non-dialysis patients and is no less effective.

  Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease that may progress to end-stage renal disease, characterized by increased kidney volume due to cystic formations. In this study, we aimed to investigate the relationship between serum uromodulin levels, total kidney volume and estimated glomerular filtration rate (eGFR) in patients with ADPKD.
 
  This study included a total of 54 ADPKD patients and 18 healthy volunteers (control group). Total kidney volumes were calculated through magnetic resonance images using ellipsoid method. Serum uromodulin measurements were measured using an ELISA method.
 
  Serum uromodulin levels were lower in patients compared with the control group (2.47 ± 0.16 vs 2.6 ± 0.28, p = 0.021). There was no significant difference in uromodulin values among the patients in chronic kidney disease (CKD) stages 1-2, 3 and 4-5. TKV measurements of CKD stage 4-5 patients were significantly higher than the stage 1-2 patients (p = 0.015). A negative cduals with ADPKD.
  This study was conducted to assess gender difference in the association of chronic kidney disease (CKD) with visceral adiposity index (VAI) and lipid accumulation product index (LAP) in Korean adults.
 
  The study was performed using data from the 2015 Korean National Health and Nutrition Examination Survey and included 4947 adults aged 20years or older.
 
  There were several key findings in the present study. First, overall, after adjusting for related variables (including age), CKD (estimated glomerular filtration rate < 60ml/min/1.73 m
  ) was positively associated with the quartiles of VAI and LAP. Second, when analyzed separately for gender, the results in men and women were different. After adjusting for the related variables (except age), CKD was positively associated with the quartiles of VAI and LAP in both men and women. After further adjustment for age, CKD was still positively associated with the quartiles of VAI and LAP in men. However, in women, the relationships between CKD and the quartiles of VAI and LAP were no longer significant.
