Objectives 1) To determine whether pRIFLE (Pediatric Risk, Injury, Failure, Loss, End Stage Renal Disease) criteria serves to characterize the pattern of Acute Kidney Injury (AKI) in critically ill pediatric patients; and 2) to identify if pRIFLE score will predict morbidity and mortality in our patient´s cohort. Design Prospective Cohort. Setting Multidisciplinary, tertiary care, 10- bed PICU. Patients 266 patients admitted to PICU from November 2009 to November 2010. Interventions None. Measurements and Main Results The incidence of AKI in the PICU was 27.4%, of which 83.5% presented within 72hrs of admission to the PICU. Patients with AKI were younger, weighed less, were more likely to be on in fluid overload ≥10%, and were more likely to be on inotropic support, diuretics or amino glycosides. No difference in gender, use of other nephrotoxins, or mechanical ventilation was observed. Fluid overload ≥10% was an independent predictor of morbidity and mortality. In multivariate analysis, AKI-Injury and Failure categories, as defined by pRIFLE, predicted mortality, hospital length of stay, and PICU length of stay. Conclusions In this cohort of critically ill pediatric patients, AKI identified by pRIFLE and fluid overload ≥ 10% predicted increased morbidity and mortality. Implementation of pRIFLE scoring and close monitoring of fluid overload upon admission may help develop early interventions to prevent and treat AKI in critically ill children.
Background Although a higher prevalence of osteoarthritis (OA) has been reported among diabetes mellitus (DM) patients, inconsistencies and limitations of observational studies have precluded a conclusive association. Objective To evaluate the association of hand or knee OA with DM in a population of Hispanics from Puerto Rico. Methods A cross-sectional study was performed in 202 subjects (100 adult DM patients as per the National Diabetes Data Group Classification, and 102 non-diabetic subjects). OA of hand and knee was ascertained using the American College of Rheumatology classification criteria. Sociodemographic characteristics, health-related behaviors, comorbidities, pharmacotherapy and DM clinical manifestations were determined. Multivariable logistic regression was used to evaluate the association of DM with hand or knee OA, and to evaluate factors associated with hand or knee OA among DM patients. Results The mean (standard deviation, SD) age for DM patients was 51.6 (13.1) years; 64.0% were females. The mean (SD) DM duration was 11.0 (10.4) years. The prevalence of OA in patients with DM and non-diabetics subjects was 49.0% and 26.5%, respectively (p<0.01). In the multivariable analysis, patients with DM had 2.18 the odds of having OA when compared to non-diabetic subjects (95% CI: 1.12–4.24). In a sub-analysis among DM patients, female patients were more likely to have hand or knee OA (OR [95% CI]: 5.06 [1.66–15.66]), whereas patients who did not use insulin alone for DM therapy were more likely to have OA (OR [95% CI]: 4.44 [1.22–16.12]). Conclusion In this population of Hispanics from Puerto Rico, DM patients were more likely to have OA of hands or knees than non-diabetic subjects. This association was retained in multivariable models accounting for established risk factors for OA. Among DM patients, females were at greater risk for OA, whereas the use of insulin was negatively associated.
Objective To determine the extent of mitochondrial DNA (mtDNA) damage in systemic lupus erythematosus (SLE) patients compared to healthy subjects and to determine the factors associated with mtDNA damage among SLE patients. Methods A cross-sectional study was performed in 86 SLE patients (per American College of Rheumatology classification criteria) and 86 healthy individuals matched for age and gender. Peripheral blood mononuclear cells (PBMCs) were collected from subjects to assess the relative amounts of mtDNA damage. Quantitative polymerase chain reaction assay was used to measure the frequency of mtDNA lesions and mtDNA abundance. Socioeconomic-demographic features, clinical manifestations, pharmacologic treatment, disease activity, and damage accrual were determined. Statistical analyses were performed using t test, pairwise correlation, and Pearson’s chi-square test (or Fisher’s exact test) as appropriate. Results Among SLE patients, 93.0% were women. The mean (SD) age was 38.0 (10.4) years and the mean (SD) disease duration was 8.7 (7.5) years. SLE patients exhibited increased levels of mtDNA damage as shown by higher levels of mtDNA lesions and decreased mtDNA abundance as compared to healthy individuals. There was a negative correlation between disease damage and mtDNA abundance and a positive correlation between mtDNA lesions and disease duration. No association was found between disease activity and mtDNA damage. Conclusion PBMCs from SLE patients exhibited more mtDNA damage compared to healthy subjects. Higher levels of mtDNA damage were observed among SLE patients with major organ involvement and damage accrual. These results suggest that mtDNA damage have a potential role in the pathogenesis of SLE.
Objectives: The hazardous environmental conditions hurricanes create might increase injury incidence almost 7 times. Therefore, a cohort study was performed at the Puerto Rico Trauma Hospital to compare morbidity and mortality patterns of patients after Hurricane Maria with a control period. Methods: Admissions from September 20, 2017, through January 20, 2018, constituted the post-Maria period (473 patients); the corresponding months of the previous year comprised the pre-Maria period (439 patients). Comparisons were done using Pearson’s chi-square or Mann-Whitney U-tests, as appropriate. A logistic regression was performed to assess the association between mortality and the study period. Results: Postlandfall admissions among patients aged 40-64 y increased by 6.6%, while among subjects between ages 18 and 39 y dropped by 7.0% (P = 0.03). Falls, gunshots, and burns were the injury mechanisms that varied the most across the exposure period. The median Injury Severity Score (13 vs 12; P = 0.05) and the frequency of Glasgow Coma Scale scores ≤8 (17.1% vs 10.9%; P = 0.03) were higher among poststorm patients. Moreover, a 2-fold (odds ratio = 1.93; 95% CI: 1.07-3.47) increase in mortality was observed after Maria, when adjusting for covariates. Conclusions: Following a hurricane, trauma centers might expect an older population, with more severe injuries and a 2-fold increased mortality risk.
