ABSTRACT

BACKGROUND: Nonrheumatic valvular diseases are common; however, no studies have estimated their global or national burden. As part of the Global Burden of Disease Study 2017, mortality, prevalence, and disability-adjusted life-years (DALYs) for calcific aortic valve disease (CAVD), degenerative mitral valve disease, and other nonrheumatic valvular diseases were estimated for 195 countries and territories from 1990 to 2017. METHODS: Vital registration data, epidemiologic survey data, and administrative hospital data were used to estimate disease burden using the Global Burden of Disease Study modeling framework, which ensures comparability across locations. Geospatial statistical methods were used to estimate disease for all countries, because data on nonrheumatic valvular diseases are extremely limited for some regions of the world, such as Sub-Saharan Africa and South Asia. Results accounted for estimated level of disease severity as well as the estimated availability of valve repair or replacement procedures. DALYs and other measures of health-related burden were generated for both sexes and each 5-year age group, location, and year from 1990 to 2017. RESULTS: Globally, CAVD and degenerative mitral valve disease caused 102 700 (95% uncertainty interval [UI], 82 700-107 900) and 35 700 (95% UI, 30 500-42 500) deaths, and 12.6 million (95% UI, 11.4 million-13.8 million) and 18.1 million (95% UI, 17.6 million-18.6 million) prevalent cases existed in 2017, respectively. A total of 2.5 million (95% UI, 2.3 million-2.8 million) DALYs were estimated as caused by nonrheumatic valvular diseases globally, representing 0.10% (95% UI, 0.09%-0.11%) of total lost health from all diseases in 2017. The number of DALYs increased for CAVD and degenerative mitral valve disease between 1990 and 2017 by 101% (95% UI, 79%-117%) and 35% (95% UI, 23%-47%), respectively. There is significant geographic variation in the prevalence, mortality rate, and overall burden of these diseases, with highest age-standardized DALY rates of CAVD estimated for high-income countries. CONCLUSIONS: These global and national estimates demonstrate that CAVD and degenerative mitral valve disease are important causes of disease burden among older adults. Efforts to clarify modifiable risk factors and improve access to valve interventions are necessary if progress is to be made toward reducing, and eventually eliminating, the burden of these highly treatable diseases.

ABSTRACT

BACKGROUND: Early readmissions are an important indicator of the quality of care. Limited data exist describing hospital readmissions in acute diverticulitis. The study aimed to describe unplanned, 30-day readmissions among adult acute diverticulitis patients and to assess readmission predictors. METHODS: We analyzed the 2013 and 2014 United States National Readmission Database and identified acute diverticulitis admissions using administrative codes in adult patients older than 18 years of age. Our primary outcome was a 30-day, unplanned readmission rate. We used Chi-square tests, t tests, and Wilcoxon rank-sum tests for descriptive analyses and survey logistic regression to calculate adjusted odds ratios (aORs) and 95% confidence intervals for associations with readmissions adjusting for confounders. RESULTS: In the cohort of 364,511 hospitalizations with acute diverticulitis, as the primary diagnosis on index admission, 31,420 (8.6%) had at least one unplanned 30-day readmission. Sixty percent of the readmissions occurred within the first 2 weeks of the index admission. The most common reasons for unplanned 30-day readmission were due to diverticulitis of the colon (41.5%), postoperative infection (4.2%), septicemia (3.6%), intestinal infection due to Clostridium difficile (3%), and other digestive system complications such bleeding or fistula (2.8%). Multivariable analysis showed advance age (> 75 years), discharge against medical advice, comorbidities (renal failure, coronary artery disease, atrial fibrillation, congestive heart failure, hypertension, diabetes, obesity, weight loss, chronic lung disease, malignancy), blood transfusion, Medicare and Medicaid insurance, and increased length of stay (> 3 days) were associated with significantly higher odds for readmission. Patients who have undergone abdominal surgery during index admission were 31% less likely to get readmitted. CONCLUSIONS: On a national level, 1 in 11 hospitalizations for acute diverticulitis was followed by unplanned readmission within 30 days with most admissions occurring in the first 2 weeks. Multiple modifiable and non-modifiable factors influencing readmission rates were noted. Further studies should examine if strategies that address these predictors can decrease readmissions.

ABSTRACT

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) can be challenging in patients with decompensated cirrhosis (DC) due to increased risk of adverse events related to liver dysfunction. Limited data exist regarding its national utilization in patients with DC. We aim to determine the trends in utilization and outcomes of ERCP among patients with DC in US hospitalizations. METHODS: We identified hospitalizations undergoing ERCP (diagnostic and therapeutic) between 2000 and 2013 from the National Inpatient Sample (NIS) database and used validated ICD9-CM codes to identify DC hospitalizations. We utilized Cochrane-Armitage test to identify changes in trends and multivariable survey regression modeling for adjusted odds ratios (aOR) for adverse outcomes and mortality predictors. RESULTS: There were 43782 cases of ERCPs performed in DC patients during the study period. Absolute number of ERCPs performed in this population from 2000 to 2013 showed an upward trend; however, the proportion of DC patients undergoing ERCP remained stable. We noted significant decrease in utilization of diagnostic ERCP and an increase of therapeutic ERCPs (P < 0.01). There was a significant decrease in the mean length of stay for DC patients undergoing ERCP from 8.2 days in 2000 to 7.2 days in 2013 (P < 0.01) with an increase in the mean cost of hospitalization from $17053 to $19825 (P < 0.001). Mortality rates showed a downward trend from 2000 to 2013 from 13.6 to 9.6% (P < 0.01). Increasing age, Hispanic race, diagnosis of hypertension and diabetes mellitus, and private insurance were related to adverse discharges(P < 0.01). Increasing age, presence of hepatic encephalopathy, and sepsis were associated with higher mortality (P < 0.01). CONCLUSIONS: There is an increasing trend in therapeutic ERCP utilization in DC hospitalizations nationally. There is an overall decrease in mortality in DC hospitalizations undergoing ERCP. This improvement in mortality suggests improvement in both procedural technique and peri-procedural care as well as overall decreasing mortality in cirrhosis.

ABSTRACT

BACKGROUND: Acute kidney injury (AKI), as defined by peak increase in serum creatinine, is independently associated with increased risk of mortality and length of stay. Studies have suggested that the duration of AKI may be an important additional or independent prognostic marker of increased mortality in patients with AKI across clinical settings. We performed a systematic review and meta-analysis of published studies to assess the impact of duration of AKI on outcomes. METHODS: Various bibliographic databases (MEDLINE, Embase, Cochrane Library, CINAHL and Web of Science) were searched through database inception to December 2015. Human, longitudinal studies with patients aged 18 or above describing outcomes of duration of AKI were included. Duration of AKI categorized as "Short" if AKI duration was ≤2 days or labeled as "transient AKI"; "Medium" for AKI durations 3-6 days and "Long" for AKI duration of ≥7 days or "non-recovered". Various outcomes looked at were Long term mortality, cardiovascular events, chronic kidney disease (CKD). RESULTS: Eighteen studies were deemed eligible for the systematic review. The outcome of long-term mortality with duration of AKI was reported in 8 studies. The pooled Risk Ratio (RR) for long-term mortality generally was higher for longer duration of AKI: short duration of AKI (n = 8 studies, RR 1.42, 95% CI 1.21-1.66), medium duration (n = 4 studies, RR 1.92, 95% CI 1.34-2.75), and long duration (n = 8 studies, RR 2.28, 95% CI 1.77-2.94) duration of AKI. Further, Duration of AKI was independently associated with higher risk of cardiovascular outcomes and incident CKD Stage 3 when stratified within each stage of AKI. CONCLUSION: Duration of AKI was independently associated with long term mortality, cardiovascular(CV) events, and development of incident CKD Stage 3.

ABSTRACT

Tumor lysis syndrome (TLS) is a life threatening emergency due to destruction and massive release of intracellular metabolites from cancer cells often resulting in acute kidney injury (AKI), sometimes severe enough to require dialysis (AKI-D). The impact of dialysis requirement in AKI has not been explored. We utilized data from the Nationwide Inpatient Sample and using International Classification of Diseases, 9th Revision, diagnoses codes for TLS, AKI and dialysis, evaluated the incidence, risk factors and impact of AKI-D on mortality, adverse discharge and length of stay (LOS). Survey multivariable logistic regression was used to compute adjusted Odds Ratios (aOR and 95% confidence intervals (CI). An estimated 12% (2,919) of all TLS hospitalizations (n = 22 875) develop AK-D. After adjustment for confounders, AKI-D was associated with greater odds of mortality (aOR 1.98; (95% CI 1.60-2.45)), adverse discharge (aOR 1.63 (95% CI 1.19-2.24)) and longer LOS (19 vs 14.6 days; P < 0.01) compared with those without AKI-D. Further studies to evaluate the association of AKI-D on long-term outcomes in patients with TLS are needed.

ABSTRACT

BACKGROUND: The epidemiology and outcomes of acute kidney injury (AKI) in prevalent non-renal solid organ transplant recipients is unknown. METHODS: We assessed the epidemiology of trends in acute kidney injury (AKI) in orthotopic cardiac and liver transplant recipients in the United States. We used the Nationwide Inpatient Sample to evaluate the yearly incidence trends (2002 to 2013) of the primary outcome, defined as AKI requiring dialysis (AKI-D) in hospitalizations after cardiac and liver transplantation. We also evaluated the trend and impact of AKI-D on hospital mortality and adverse discharge using adjusted odds ratios (aOR). RESULTS: The proportion of hospitalizations with AKI (9.7 to 32.7% in cardiac and 8.5 to 28.1% in liver transplant hospitalizations; ptrend<0.01) and AKI-D (1.63 to 2.33% in cardiac and 1.32 to 2.65% in liver transplant hospitalizations; ptrend<0.01) increased from 2002-2013. This increase in AKI-D was explained by changes in race and increase in age and comorbidity burden of transplant hospitalizations. AKI-D was associated with increased odds of in hospital mortality (aOR 2.85; 95% CI 2.11-3.80 in cardiac and aOR 2.00; 95% CI 1.55-2.59 in liver transplant hospitalizations) and adverse discharge [discharge other than home] (aOR 1.97; 95% CI 1.53-2.55 in cardiac and 1.91; 95% CI 1.57-2.30 in liver transplant hospitalizations). CONCLUSIONS: This study highlights the growing burden of AKI-D in non-renal solid organ transplant recipients and its devastating impact, and emphasizes the need to develop strategies to reduce the risk of AKI to improve health outcomes.

ABSTRACT

INTRODUCTION: Urinary biomarkers of kidney injury are presumed to reflect renal tubular damage. However, their concentrations may be influenced by other factors, such as hematuria or pyuria. We sought to examine what non-injury related urinalysis factors are associated with urinary biomarker levels. METHODS: We examined 714 adults who underwent cardiac surgery in the TRIBE-AKI cohort that did not experience post-operative clinical AKI (patients with serum creatinine change of ≥ 20% were excluded). We examined the association between urinalysis findings and the pre- and first post-operative urinary concentrations of 4 urinary biomarkers: neutrophil gelatinase-associated lipocalin (NGAL), interleukin-18 (IL-18), kidney injury molecule-1 (KIM-1), and liver fatty acid binding protein (L-FABP). RESULTS: The presence of leukocyte esterase and nitrites on urinalysis was associated with increased urinary NGAL (R2 0.16, p < 0.001 and R2 0.07, p < 0.001, respectively) in pre-operative samples. Hematuria was associated with increased levels of all 4 biomarkers, with a much stronger association seen in post-operative samples (R2 between 0.02 and 0.21). Dipstick proteinuria concentrations correlated with levels of all 4 urinary biomarkers in pre-operative and post-operative samples (R2 between 0.113 and 0.194 in pre-operative and between 0.122 and 0.322 in post-operative samples). Adjusting the AUC of post-operative AKI for dipstick proteinuria lowered the AUC for all 4 biomarkers at the pre-operative time point and for 2 of the 4 biomarkers at the post-operative time point. CONCLUSIONS: Several factors available through urine dipstick testing are associated with increased urinary biomarker concentrations that are independent of clinical kidney injury. Future studies should explore the impact of these factors on the prognostic and diagnostic performance of these AKI biomarkers.

ABSTRACT

BACKGROUND: Data from experimental animals suggest that probiotic supplements may retard CKD progression. However, the relationship between probiotic use, frequent yogurt consumption (as a natural probiotic source), and kidney parameters have not been evaluated in humans. FINDINGS: We utilized NHANES data, and analyzed the association of probiotic alone (1999-2012) and yogurt/probiotic (2003-2006) use with albuminuria and eGFR after adjustment for demographic and clinical parameters. Frequent yogurt consumption was defined as thrice or more weekly over the year prior to the interview. Frequent yogurt/probiotic consumers had lower adjusted odds of developing combined outcome (albuminuria and/or eGFR < 60 ml/min/1.73 m(2)) compared to infrequent consumers (OR = 0.76; 95 % CI = 0.61-0.94). When evaluated separately, frequent consumers had lower odds of albuminuria and nonsignificant trend towards decreased odds of low eGFR compared to infrequent consumers. In the probiotic cohort, probiotic consumers were found to have a lower adjusted odds of albuminuria compared to nonusers (OR = 0.59; 95 % CI = 0.37-0.94). CONCLUSION: Frequent yogurt and/or probiotics use is associated with decreased odds of proteinuric kidney disease. These hypothesis-generating results warrant further translational studies to further delineate the relationship between yogurt/probiotics with kidney dysfunction, as well as microbiome and dysbiosis as potential mediators.

ABSTRACT

OBJECTIVES: The objective of this study was to compare safety and efficacy of patent foramen ovale (PFO) closure compared with medical therapy in patients with cryptogenic stroke (CS). BACKGROUND: The role of PFO closure in preventing recurrent stroke in patients with prior CS has been controversial. METHODS: We searched PubMed, EMBASE, the Cochrane Central Register of Controlled trials, and the clinical trial registry maintained at clinicaltrials.gov for randomized control trials that compared device closure with medical management and reported on subsequent stroke and adverse events. Event rates were compared using a forest plot of relative risk using a random-effects model assuming interstudy heterogeneity. RESULTS: A total of 6 studies (n = 3747) were included in the final analysis. Mean follow-up ranged from 2 to 5.9 years. Pooled analysis revealed that device closure compared to medical management was associated with a significant reduction in stroke (risk ratio [RR] = 0.41, 95% CI = 0.20-0.83, I2 = 51%, P = 0.01). There was, however, a significant increase in atrial fibrillation with device therapy (RR = 5.29, 95% CI = 2.32-12.06, I2 = 38%, P < 0.0001). No effect was observed on major bleeding (P = 0.50) or mortality (P = 0.42) with device therapy. Subgroup analyses showed that device closure significantly reduced the incidence of the composite primary end point among patients who had large shunt sizes (RR = 0.35, 95% CI = 0.18-0.68, I2 = 27%, P = 0.002). The presence/absence of atrial septal aneurysm (P = 0.52) had no effect on the outcome. CONCLUSION: PFO closure is associated with a significant reduction in the risk of stroke compared to medical management. However, it causes an increased risk of atrial fibrillation.

ABSTRACT

Despite increasing medical complexity in patients with heart failure (HF), there are limited data on incidence and outcomes for patients with HF needing respiratory support. This study sought to examine contemporary trends of respiratory support strategies among patients with HF. Using the National Inpatient Sample, we identified adults aged greater than 18 years hospitalized with a primary diagnosis of HF. We assessed for trends in the use of invasive mechanical ventilation (IMV) and noninvasive ventilation (NIV), length of stay, hospital costs, and in-hospital mortality. From 2002 to 2014, we identified 9,508,768 HF hospitalizations, which included 202,340 (2.13%) and 257,549 (2.71%) patients that required IMV and NIV, respectively. Over the study period, the proportion of HF patients requiring IMV significantly decreased (3.25% in 2002 to 1.56% in 2014) whereas the use of NIV significantly increased from 0.95% to 7.25% (ptrend <0.001 for both). In-hospital mortality significantly increased for IMV (31.5% in 2002 to 38.6% in 2014) recipients and decreased for patients requiring NIV (9.0% to 5.6%, ptrend <0.0001 for both). The average length of stay was nearly 7 days longer in the IMV group (12.2 days) and 2 days longer in the NIV group (6.8 days; p <0.001 for both). Hospital charges have nearly tripled for patients requiring IMV ($99,358 in 2014, ptrend <0.001) and doubled for those requiring NIV ($37,539 in 2014, ptrend <0.001). In conclusion, respiratory support strategies for patients with HF have significantly evolved with increasing use of NIV as compared with IMV. However, the in-hospital mortality associated with respiratory failure remains unacceptably high.

ABSTRACT

The incidence of new human immunodeficiency virus (HIV) infections is declining and is half of what it was in the mid 1990s. We present a case of newly diagnosed HIV with acquired immune deficiency syndrome (AIDS), Neurosyphilis, Kaposi Sarcoma, and multiple opportunistic infections. Although this type of patient was not uncommon in the pre-antiretroviral era, we do not often see such a constellation of conditions in a single individual. The significance of this case lies not in the diagnosis, but rather in the number of the diagnoses and the thought process used to attain them.

ABSTRACT

BACKGROUND: There is no convincing data on the trends of hospitalizations, mortality, cost, and demographic variations associated with inpatient admissions for gastric cancer in the USA. The aim of this study was to use a national database of US hospitals to evaluate the trends associated with gastric cancer. METHODS: We analyzed the National Inpatient Sample (NIS) database for all patients in whom gastric cancer (ICD-9 code: 151.0, 151.1, 151.2, 151.3, 151.4, 151.5, 151.6, 151.8, 151.9) was the principal discharge diagnosis during the period, 2003-2014. The NIS is the largest publicly available all-payer inpatient care database in the US. It contains data from approximately eight million hospital stays each year. The statistical significance of the difference in the number of hospital discharges, length of stay, and hospital costs over the study period was determined by regression analysis. RESULTS: In 2003, there were 23,921 admissions with a principal discharge diagnosis of gastric cancer as compared to 21,540 in 2014 (P < 0.01). The mean length of stay for gastric cancer decreased by 17% between 2003 and 2014 from 10.9 days to 8.95 days (P < 0.01). However, during this period, the mean hospital charges increased significantly by 21% from $ 75,341 per patient in 2003 to $ 91,385 per patient in 2014 (P < 0.001). There was a more significant reduction in mortality over a period of 11 years from 2428 (10.15%) in 2003 to 1345 (6.24%) in 2014 (P < 0.01). The aggregate charges (i.e., "national bill") for gastric cancer increased significantly from 1.79 bn $ to 1. 96 bn $ (P < 0.001), despite decrease in hospitalization (inflation adjusted). CONCLUSION: Although the number of inpatient admissions for gastric cancer have decreased over the past decade, the healthcare burden and cost related to it has increased significantly. Inpatient mortality is decreasing which is consistent with overall decrease in gastric cancer-related deaths. Cost increase associated with gastric cancer contributed significantly to the national healthcare bill.

ABSTRACT

The number of patients with advanced heart failure receiving left ventricular assist device (LVAD) implantation has increased dramatically over the last decade. There are limited data available about the nationwide trends of complications leading to readmissions after implantation of contemporary devices. Patients who underwent LVAD implantation from January 2013 to December 2013 were identified using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code 37.66 from the Healthcare Cost and Utilization Project's National Readmission Database. The top causes of unplanned 30-day readmission after LVAD implantation were determined. Survey logistic regression was used to analyze the significant predictors of readmission. In 2013, there were 2,235 patients with an LVAD implantation. Of them, 665 (29.7%) had at least 1 unplanned readmission within 30 days, out of which 289 (43.4%) occurred within 10 days after discharge. Implant complications (14.9%), congestive heart failure (11.7%), and gastrointestinal bleeding (8.4%) were the top 3 diagnoses for the first readmission and accounted for more than a third of all readmissions. Significant predictors of readmissions included a prolonged length of stay during the index admission, Medicare insurance, and discharge to short-term facility. In conclusion, despite increased experience with LVADs, unplanned readmissions within 30 days of implantation remain significantly high.

ABSTRACT

Patients with kidney disease (KD) are at increased risk for cerebrovascular disease (CVD) and CVD patients with KD have worse outcomes. We aimed to determine the representation of KD patients in major randomized controlled trials (RCTs) of CVD interventions. We searched MEDLINE for reports of major CVD trials published through February 9, 2017. We excluded trials that did not report mortality outcomes, enrolled fewer than 100 participants, or were subgroup, follow-up, or post-hoc analyses. Two independent reviewers performed study selection and data extraction. We included 135 RCTs randomizing 194,977 participants. KD patients were excluded in 48 (35.6%) trials, but were less likely to be excluded from trials of class I/II recommended interventions (n = 7; 15.9%; p = 0.001) and more likely to be excluded in trials with registered protocols (45.5% vs. 22.4%; p = 0.007). Exclusion was lower in trials supported by academic or governmental grants compared to industry or combined funding (21.2% vs. 42.0% and 47.8%; p = 0.033 and 0.028, respectively). Among trials excluding KD patients, 24 (50.0%) used serum creatinine, 7 (14.6%) used estimated glomerular filtration rate or creatinine clearance, 7 (14.6%) used renal replacement therapy, and 19 (39.6%) used non-specific kidney-related criteria. Only 4 (3.0%) trials reported baseline renal function. No trials prespecified or reported subgroup analyses by baseline renal function. Although 19 (14.1%) trials reported the incidence of acute kidney injury, no trial examined adverse event rates according to renal function. In summary, more than one third of major CVD trials excluded patients with KD, primarily based on serum creatinine or non-specific criteria, and outcomes were not stratified by renal parameters. Therefore, purposeful efforts to increase inclusion of KD patients in CVD trials and evaluate the impact of renal function on efficacy and safety are needed to improve the quality of evidence for interventions in this vulnerable population.

ABSTRACT

OBJECTIVES: This study aimed to describe the temporal trends and outcomes of endovascular and surgical revascularization in a large, nationally representative sample of patients with end-stage renal disease on hemodialysis hospitalized for peripheral artery disease (PAD). BACKGROUND: PAD is prevalent among patients with end-stage renal disease on hemodialysis and is associated with significant morbidity and mortality. There is a paucity of information on trends in endovascular and surgical revascularization and post-procedure outcomes in this population. METHODS: We used the Nationwide Inpatient Sample (2002 to 2012) to identify hemodialysis patients undergoing endovascular or surgical procedures for PAD using diagnostic and procedural codes. We compared trends in amputation, post-procedure complications, mortality, length of stay, and costs between the 2 groups using trend tests and logistic regression. RESULTS: There were 77,049 endovascular and 29,556 surgical procedures for PAD in hemodialysis patients. Trend analysis showed that endovascular procedures increased by nearly 3-fold, whereas there was a reciprocal decrease in surgical revascularization. Post-procedure complication rates were relatively stable in persons undergoing endovascular procedures but nearly doubled in those undergoing surgery. Surgery was associated with 1.8 times adjusted odds (95% confidence interval: 1.60 to 2.02) for complications and 1.6 times the adjusted odds for amputations (95% confidence interval: 1.40 to 1.75) but had similar mortality (adjusted odds ratio: 1.05; 95% confidence interval: 0.85 to 1.29) compared with endovascular procedures. Length of stay for endovascular procedures remained stable, whereas a decrease was seen for surgical procedures. Overall costs increased marginally for both procedures. CONCLUSIONS: Rates of endovascular procedures have increased, whereas those of surgeries have decreased. Surgical revascularization is associated with higher odds of overall complications. Further prospective studies and clinical trials are required to analyze the relationship between the severity of PAD and the revascularization strategy chosen.

ABSTRACT

Peritoneal dialysis (PD) is an effective but underutilized renal replacement therapy modality. There are limited data regarding geographical variation in PD catheter insertion and utilization of PD as a first renal replacement therapy in the United States. We explored the variation in catheter insertion and initiation of PD utilizing 2 large, nationally representative databases. The incidence of catheter insertion differed significantly by geographical region, being highest in the South (7.30/100 end-stage renal disease [ESRD] patients; 95% confidence [CI] interval 6.78 - 7.81) and lowest in the West (5.91/100 ESRD patients; 95% CI 5.43 - 6.38). Peritoneal dialysis initiation also differed by region, being highest in the West (7.10/100 ESRD patients; 95% CI 6.83 - 7.30) and lowest in the Northeast (5.12/100 ESRD patients; 95% CI 4.87 - 5.30). Interestingly, the Northeast region, with the lowest rate of PD utilization, had the highest number of nephrologists per population (3.95/100,000 persons), and the West, with the highest PD utilization, had the lowest number of nephrologists (2.54/100,000 persons). Reasons for this variation should be explored further and efforts should be made to standardize PD implementation throughout the United States.

ABSTRACT

BACKGROUND AND AIMS: Cirrhosis affects 5.5 million patients with estimated costs of US$4 billion. Previous studies about dialysis requiring acute kidney injury (AKI-D) in decompensated cirrhosis (DC) are from a single center/year. We aimed to describe national trends of incidence and impact of AKI-D in DC hospitalizations. METHODS: We extracted our cohort from the Nationwide Inpatient Sample (NIS) from 2006-2012. We identified hospitalizations with DC and AKI-D by validated ICD9 codes. We analyzed temporal changes in DC hospitalizations complicated by AKI-D and utilized multivariable logistic regression models to estimate AKI-D impact on hospital mortality. RESULTS: We identified a total of 3,655,700 adult DC hospitalizations from 2006 to 2012 of which 78,015 (2.1 %) had AKI-D. The proportion with AKI-D increased from 1.5 % in 2006 to 2.23 % in 2012; it was stable between 2009 and 2012 despite an increase in absolute numbers from 6773 to 13,930. The overall hospital mortality was significantly higher in hospitalizations with AKI-D versus those without (40.87 vs. 6.96 %; p < 0.001). In an adjusted multivariable analysis, adjusted odds ratio for mortality was 2.17 (95 % CI 2.06-2.28; p < 0.01) with AKI-D, which was stable from 2006 to 2012. Changes in demographics and increases in acute/chronic comorbidities and procedures explained temporal changes in AKI-D. CONCLUSIONS: Proportion of DC hospitalizations with AKI-D increased from 2006 to 2009, and although this was stable from 2009 to 2012, there was an increase in absolute cases. These results elucidate the burden of AKI-D on DC hospitalizations and excess associated mortality, as well as highlight the importance of prevention, early diagnosis and testing of novel interventions in this vulnerable population.

ABSTRACT

BACKGROUND: Atrial fibrillation (AF) is a common cause for hospitalization, but there are limited data regarding acute kidney injury requiring dialysis (AKI-D) in AF hospitalizations. We aimed to assess temporal trends and outcomes in AF hospitalizations complicated by AKI-D utilizing a nationally representative database. METHODS AND RESULTS: Utilizing the Nationwide Inpatient Sample, AF hospitalizations and AKI-D were identified using diagnostic and procedure codes. Trends were analyzed overall and within subgroups and utilized multivariable logistic regression to generate adjusted odds ratios (aOR) for predictors and outcomes including mortality and adverse discharge. Between 2003 and 2012, 3751 (0.11%) of 3 497 677 AF hospitalizations were complicated by AKI-D. The trend increased from 0.3/1000 hospitalizations in 2003 to 1.5/1000 hospitalizations in 2012, with higher increases in males and black patients. Temporal changes in demographics and comorbidities explained a substantial proportion but not the entire trend. Significant comorbidities associated with AKI-D included mechanical ventilation (aOR 13.12; 95% CI 9.88-17.43); sepsis (aOR 8.20; 95% CI 6.00-11.20); and liver failure (aOR 3.72; 95% CI 2.92-4.75). AKI-D was associated with higher risk of in-hospital mortality (aOR 3.54; 95% CI 2.81-4.47) and adverse discharge (aOR 4.01; 95% CI 3.12-5.17). Although percentage mortality within AKI-D decreased over the decade, attributable risk percentage mortality remained stable. CONCLUSIONS: AF hospitalizations complicated by AKI-D have quintupled over the last decade with differential increase by demographic groups. AKI-D is associated with significant morbidity and mortality. Without effective AKI-D therapies, focus should be on early risk stratification and prevention to avoid this devastating complication.

ABSTRACT

Primary gastrointestinal (GI) lymphomas constitute about 5.6 per cent of total gut neoplasms. The involvement of large bowel as primary site is all the more rare. We carried out this study to evaluate the prevalence and clinicopathological features of large bowel lymphoma at Gujarat Cancer and Research Institute and to compare our findings with published literature. We carried out a retrospective analysis of the records of histologically diagnosed cases of large bowel lymphoma over a 5 year period. A total of eight cases of large bowel lymphoma were identified compared with 57 cases of primary GI lymphoma of other sites, constituting about 12.3 per cent (eight of 65) of all GI lymphomas. Peak incidence was observed in the second decade of life with a mean age at presentation of 30.6 years (range 4-70 years). A male-to-female ratio of one to two was observed. The most commonly presenting feature was altered bowel habits and diarrhea in more than 50 per cent of the patients. One patient presented with acute intestinal obstruction. Diagnosis was made by colonoscopic biopsies in all but one case. All of the patients were treated with surgery and adjuvant chemotherapy. A 4-year disease-free survival of 66.7 per cent was observed (95% confidence interval 0.05-1.28). There was no significant difference in survival in patients with high-grade versus low-grade tumors (50% vs 66.7%; P = 0.88) and stage of disease (75% vs 50%; P = 0.45) in stage II and III respectively. We conclude that large bowel lymphoma is a curable disease if treated aggressively. We suggest that all patients should be treated by primary surgery and should receive adjuvant chemotherapy.
