Abstract

Introduction: Prior cross-sectional studies suggest that health-related quality of life (HRQOL) worsens with more severe glomerular disease. This longitudinal analysis was conducted to assess changes in HRQOL with changing disease status. Methods: Cure Glomerulonephropathy (CureGN) is a cohort of patients with minimal change disease, focal segmental glomerulosclerosis, membranous nephropathy, IgA vasculitis, or IgA nephropathy. HRQOL was assessed at enrollment and follow-up visits 1 to 3 times annually for up to 5 years with the Patient-Reported Outcomes Measurement Information System (PROMIS). Global health, anxiety, and fatigue domains were measured in all; mobility was measured in children; and sleep-related impairment was measured in adults. Linear mixed effects models were used to evaluate HRQOL responsiveness to changes in disease status. Results: A total of 469 children and 1146 adults with PROMIS scores were included in the analysis. HRQOL improved over time in nearly all domains, though group-level changes were modest. Edema was most consistently associated with worse HRQOL across domains among children and adults. A greater number of symptoms also predicted worse HRQOL in all domains. Sex, age, obesity, and serum albumin were associated with some HRQOL domains. The estimated glomerular filtration rate (eGFR) was only associated with fatigue and adult physical health; proteinuria was not associated with any HRQOL domain in adjusted models. Conclusion: HRQOL measures were responsive to changes in disease activity, as indicated by edema. HRQOL over time was not predicted by laboratory-based markers of disease. Patient-reported edema and number of symptoms were the strongest predictors of HRQOL, highlighting the importance of the patient experience in glomerular disease. HRQOL outcomes inform understanding of the patient experience for children and adults with glomerular diseases.

Abstract

Introduction Glomerular diseases are characterized by variable disease activity over many years. We aimed to analyze the relationship between clinical disease activity and duration of glomerular disease. Methods Disease activity in adults with chronic minimal change disease, focal segmental glomerulosclerosis, membranous nephropathy, and IgA nephropathy (IgAN; first diagnostic biopsy >5 years before enrollment; Of Longstanding Disease [OLD] cohort, n = 256) followed at Columbia University Medical Center (CUMC), was compared with disease activity of an internal and external cohort of patients with first diagnostic biopsy, Graphical abstract

Abstract

A root cause failure investigation was performed on anomalous (early) MIM capacitor failures on an HBT MMIC process. These failures were only observed on capacitors in the actual MMICs; process control monitor (PCM) capacitors were nominal. Multiple failure analysis techniques were employed to determine the most probable root cause of the early failures. The root cause was determined to be etching of the capacitor dielectric by a chemical used in the MMIC fabrication process, at a step after the capacitors themselves were fully built. It was determined that only CAD layouts with certain features were susceptible to the etching. These features were not present on the PCM capacitors. A design based corrective action was recommended to eliminate the failure mechanism. The effectiveness of the corrective actions was verified with several designed processing experiments. These experiments also demonstrated that the failure rate of the faulty parts increased with the time (even if the parts were not in operation). Finally, the experiments showed that the reliability of a nominal capacitor with a BCB layer on top was better than that of an identical capacitor without the BCB layer. Capacitor reliability model For the sake of completeness, the following discussion on ramped voltage TDDB testing of capacitors is included. In this work, ramped voltage data was not used to predict capacitor lifetimes, but it was used to quantitatively compare capacitor reliability by plotting percent cumulative failure versus failure voltage. Normally, destructive ramped voltage testing and the linear field model are employed in order to estimate the lifetime of capacitors. This method has been described in detail elsewhere for intrinsic capacitors (Cramer et al. [1] , [2] , [3] ). It is generally assumed that defects on or in the capacitor bottom plate or in dielectric itself causes a localized thinning of the dielectric which shortens the intrinsic lifetime of the capacitor, as illustrated in Fig. 2. Extrinsic capacitors require a refinement of the Nominal Thickness Method to the Effective Thickness Method. Typically, plots of percent cumulative failure versus failure voltage will be transformed into plots of percent cumulative failure versus lifetime via the above equations. The shapes of these two plots are nearly identical, only the values on the abscissa are changed from (linear) voltage to (logarithmic) lifetime. Since, in this work, the effort was directed at root cause determination of anomalous failures rather than predictions of expected lifetimes, the linear field model was never employed and the data was always plotted as a function of failure voltage.
