Background: Despite the high mortality of cardiovascular disease (CVD) in diabetic patients with renal injury, few studies have compared cardiovascular characteristics and outcomes between patients with diabetic nephropathy (DN) and non-diabetic renal disease (NDRD). Methods: A total of 326 type 2 diabetes mellitus patients with renal biopsy were assigned to DN and NDRD groups. Echocardiography and Doppler ultrasound were performed to evaluate left ventricular hypertrophy (LVH) and peripheral atherosclerosis disease (PAD). Renal and cardiovascular survival rates were compared between the DN and NDRD groups by Kaplan-Meier analysis. Risk factors for renal and cardiovascular events in DN patients were identified by a Cox proportional hazards model. Results: In total, 179 patients entered the DN group (54.9%) and 147 made up the NDRD group (45.1%). The presence of diabetic retinopathy, family history of diabetes, and dependence on insulin therapy were associated with the presence of DN. DN patients had more CVD with more severe LVH and PAD. Poorer renal (log-rank χ2 = 26.534, p < 0.001) and cardiovascular (log-rank χ2 = 16.257, p < 0.001) prognoses were seen in the DN group. DR (HR 1.539, 95% CI 1.332–1.842), eGFR (HR 0.943, 95% CI 0.919–0.961), and 24-h proteinuria (HR 1.211, 95% CI 1.132–1.387) were identified as risk factors for renal endpoints. Age (HR 1.672, 95% CI 1.487–1.821), HbA1C (HR 1.398, 95% CI 1.197–1.876), and 24-h proteinuria (HR 1.453, 95% CI 1.289–1.672) were associated with cardiovascular endpoints. Conclusion: Patients with DN had more severe CVD along with poorer renal and cardiovascular prognoses than those with NDRD.

Clinical Consequences

Background: Patients with short bowel syndrome (SBS) are at a high risk of cholestasis or cholelithiasis. This study aimed to determine the incidence, risk factors, and clinical consequences of cholelithiasis in adults with SBS over an extended period.Methods: All eligible adults diagnosed with SBS and admitted to a tertiary hospital center between January 2010 and December 2019 were retrospectively identified from the hospital records database. Kaplan–Meier analysis was used to estimate the cumulative incidence of SBS during the 10-year period. For assessment the risk factors for cholelithiasis, we used multivariate Cox proportional hazards model with estimation of hazard ratio (HR) with 95% confidence intervals (95 %CI).Results: This study enrolled 345 eligible patients with SBS. Kaplan–Meier analysis revealed that 72 patients (20.9%) developed cholelithiasis during the 10-year observation period. In multivariate analyses using the Cox proportional hazard model revealed that the remnant jejunum (HR = 2.163; 95% confidence interval [CI]: 1.156–4.047, p = 0.016) and parenteral nutrition dependence (HR = 1.783; 95% CI: 1.077–2.952, p = 0.025) were independent risk factors for cholelithiasis in adults with SBS. Twenty-eight patients developed symptoms and/or complications in the cholelithiasis group. Proportions of acute cholecystitis or cholangitis and acute pancreatitis were significantly increased in the cholelithiasis group compared with the non-cholelithiasis group (31.9 vs. 7.7%, p &lt; 0.01; and 6.9 vs. 1.1%, p = 0.003, respectively).Conclusion: Because of the adverse clinical consequences of cholelithiasis, adult patients with SBS should be closely monitored, and preventive interventions should be considered.Clinical Trial Registration:www.ClinicalTrials.gov, identifier: NCT04867538.

The prognosis of different etiologies of liver cirrhosis (LC) is not well understood. Previous studies performed on alcoholic LC-dominated cohorts have demonstrated a few conflicting results. We aimed to compare the outcome and the effect of comorbidities on survival between alcoholic and non-alcoholic LC in a viral hepatitis-dominated LC cohort. We identified newly diagnosed alcoholic and non-alcoholic LC patients, aged ≥40 years old, between 2006 and 2011, by using the Longitudinal Health Insurance Database. The hazard ratios (HRs) were calculated using the Cox proportional hazards model and the Kaplan–Meier method. A total of 472 alcoholic LC and 4313 non-alcoholic LC patients were identified in our study cohort. We found that alcoholic LC patients were predominantly male (94.7% of alcoholic LC and 62.6% of non-alcoholic LC patients were male) and younger (78.8% of alcoholic LC and 37.4% of non-alcoholic LC patients were less than 60 years old) compared with non-alcoholic LC patients. Non-alcoholic LC patients had a higher rate of concomitant comorbidities than alcoholic LC patients (79.6% vs. 68.6%, p < 0.001). LC patients with chronic kidney disease demonstrated the highest adjusted HRs of 2.762 in alcoholic LC and 1.751 in non-alcoholic LC (all p < 0.001). In contrast, LC patients with hypertension and hyperlipidemia had a decreased risk of mortality. The six-year survival rates showed no difference between both study groups (p = 0.312). In conclusion, alcoholic LC patients were younger and had lower rates of concomitant comorbidities compared with non-alcoholic LC patients. However, all-cause mortality was not different between alcoholic and non-alcoholic LC patients.

Background/AimsTo investigate the risk factors for disease progression of normal-tension glaucoma (NTG) with pretreatment intraocular pressure (IOP) in the low-teens.MethodsOne-hundred and two (102) eyes of 102 patients with NTG with pretreatment IOP≤12 mm Hg who had been followed up for more than 60 months were retrospectively enrolled. Patients were divided into progressor and non-progressor groups according to visual field (VF) progression as correlated with change of optic disc or retinal nerve fibre layer defect. Baseline demographic and clinical characteristics including diurnal IOP and 24 hours blood pressure (BP) were compared between the two groups. The Cox proportional hazards model was used to identify the risk factors for disease progression.ResultsThirty-six patients (35.3%) were classified as progressors and 66 (64.7%) as non-progressors. Between the two groups, no significant differences were found in the follow-up periods (8.7±3.4 vs 7.7±3.2 years; p=0.138), baseline VF mean deviation (−4.50±5.65 vs −3.56±4.30 dB; p=0.348) or pretreatment IOP (11.34±1.21 vs 11.17±1.06 mm Hg; p=0.121). The multivariate Cox proportional hazards model indicated that greater diurnal IOP at baseline (HR=1.609; p=0.004), greater fluctuation of diastolic BP (DBP; HR=1.058; p=0.002) and presence of optic disc haemorrhage during follow-up (DH; HR=3.664; p=0.001) were risk factors for glaucoma progression.ConclusionIn the low-teens NTG eyes, 35.3% showed glaucoma progression during the average 8.7 years of follow-up. Fluctuation of DBP and diurnal IOP as well as DH were significantly associated with greater probability of disease progression.

Background: Modifiable risk-factors associated with Clostridioides difficile infection (CDI) in renal-transplant (RTX) have not been clearly established and peri-transplant risk has not been described. Objective: Evaluate epidemiology, risk-factors and outcomes after CDI occurring in the first 90 days after RTX (CDI-90).Methods: Observational cohort study/survival analysis of adult RTX recipients from 1/1/2012-12/31/2015. Primary outcome was CDI-90 incidence/risk-factors. Secondary outcome was evaluation of post-90 day transplant outcomes. Results: 982 patients met inclusion criteria; 46 with CDI-90 and 936 without (comparator). CDI incidence in the total population was 4.7% at 90 days, 6.3% at 1 year, and 6.4% at 3 years. Incidence of CDI-90 was 5%; time to diagnosis was 19.4±25 days (median 7). Risk-factors for CDI-90 were alemtuzumab induction (Hazard ratio [HR] 1.5, 95% CI(1.1-2.0), p = 0.005) and age at transplant (HR 1.007/year, 95% CI (1.002-1.012), p= 0.007). However, risk-factors for CDI at any time were different; donation-after-circulatory-death (DCD) donor (HR 2.5 95% CI (1.3-4.9), p = 0.008) and female gender (HR 1.6 95% CI (1.0-2.7), p = 0.049). On Kaplan-Meier, CDI-90 appeared to have an impact on patient/graft survival, however when analyzed in a multivariable stepwise Cox proportional hazards model, only age was significantly associated with survival ( p = 0.002). Conclusion and Relevance: Incidence of CDI-90 is low, mostly occurring in the first post-operative month. Risk-factors vary temporally based on time from transplant. In the early post-op period induction agent and age at transplant are significant, but not after. Associations between CDI and negative graft outcomes appear to be largely driven by age. Future studies validating these risk-factors as well as targeted prophylaxis strategies and their effect on long term graft outcomes and the host microbiome are needed.

Purpose. The morbidity of esophageal adenocarcinoma (EAC) has significantly increased in Western countries. We aimed to identify trends in incidence and survival in patients with EAC in the recent 30 years and then analyzed potential risk factors, including race, sex, age, and socioeconomic status (SES). Methods. All data were collected from the Surveillance, Epidemiology, and End Results or SEER database. Kaplan–Meier analysis and the Cox proportional hazards model were conducted to compare the differences in survival between variables, including sex, race, age, and SES, as well as to evaluate the association of these factors with prognosis. Results. A total of 16,474 patients with EAC were identified from 1984 to 2013 in the United States. Overall incidence increased every 10 years from 1.8 to 3.1 to 3.9 per 100. Overall survival gradually improved (p<0.0001), which was evident in male patients ((hazard ratio (HR) = 1.111; 95% confidence interval (CI) (1.07, 1.15)); however, the 5-year survival rate remained low (20.1%). The Cox proportional hazards model identified old age, black ethnicity, and medium/high poverty as risk factors for EAC (HR = 1.018; 95% CI (1.017, 1.019; HR = 1.240, 95% CI (1.151,1.336), HR = 1.000, 95% CI (1.000, 1.000); respectively). Conclusions. The incidence of EAC in the United States increased over time. Survival advantage was observed in white patients and patients in the low-poverty group. Sex was an independent prognostic factor for EAC, but this finding has to be confirmed by further research.

ObjectiveThe intent of this study was to evaluate the clinical outcome and risk factors affecting mortality of the continuous ambulatory peritoneal dialysis (CAPD) patients in a single peritoneal dialysis (PD) center over a period of 10 years.Patients and methodsWe retrospectively analyzed patients on PD from June 2001 to June 2011. The clinical and biochemical data were collected from the medical records. Clinical variables included gender, age at the start of PD, smoking status, body mass index (BMI), cause of end-stage renal disease (ESRD), presence of diabetes mellitus and blood pressure. Biochemical variables included hemoglobin, urine volume, residual renal function (RRF), serum albumin, blood urea nitrogen (BUN), creatinine, total cholesterol, triglyceride, comorbidities, and outcomes. Survival curves were made by the Kaplan-Meier method. Univariate and multivariate analyses to identify mortality risk factors were performed using the Cox proportional hazard regression model.ResultsA total of 421 patients were enrolled, 269 of whom were male (63.9%). The mean age at the start of PD was 57.9 ± 14.8 years. Chronic glomerulonephritis was the most common cause of ESRD (39.4%). Estimation of patient survival by Kaplan-Meier was 92.5%, 80.2%, 74.4%, and 55.7% at 1, 3, 5, and 10 years, respectively. Patient survival was associated with age (hazard ratio [HR]: 1.641 [1.027 – 2.622], p = 0.038), cardiovascular disease (HR: 1.731 [1.08 – 2.774], p = 0.023), hypertriglyceridemia (HR: 1.782 [1.11 – 2.858], p = 0.017) in the Cox proportional hazards model analysis. Estimation of technique survival by Kaplan-Meier was 86.7%, 68.8%, 55.7%, and 37.4% at 1, 3, 5, and 10 years, respectively. In the Cox proportional hazards model analysis, age (HR: 1.672 [1.176 – 2.377], p = 0.004) and hypertriglyceridemia (HR: 1.511 [1.050 – 2.174], p = 0.026) predicted technique failure.ConclusionThe PD patients in our center exhibited comparable or even superior patient survival and technical survival rates, compared with reports from other centers in China and other countries.

721 Background: Combination chemoradiotherapy is the standard of care for treatment of non-metastatic squamous cell carcinoma of the anus (SCCA). This population-based study evaluated disparities in receipt of radiotherapy (RT) and its effect on survival in patients with localized and regional SCCA in the United States. Methods: The Surveillance, Epidemiology, and End Results (SEER) 18 database was used to identify patients with localized and regional SCCA diagnosed between 1998 and 2008. We used univariate and multivariate logistic regression to model the relationships between receipt of RT and age, sex, marital status, stage, and race. Relative survival rates were calculated and compared using two sample z-tests. A Cox proportional hazards model was used to find adjusted hazard ratios (HR). Results: A total of 3,971 patients with localized or regional SCCA as the only primary malignancy were included in the study, of which 3,278 (82.6%) received RT. After adjusting for covariates, those 65 years and older (adjusted OR 0.82, p=0.029) were less likely to receive RT. Females were more likely to receive RT compared to males (adjusted OR 1.54, p<0.001). We found no difference in receipt of RT by race. Comparisons of 1- and 5-year relative survival rates showed lower survival for blacks (p-value <0.01 at 1-year and <0.0001 at 5-years), those 65 years and older, and males. A 1-year survival disparity was found for those not receiving RT (p-value <0.0001 at 1-year), but no difference was observed at 5-years. A Cox proportional hazards model adjusting for all covariates showed greater hazard for blacks (adjusted HR 1.36, p=0.001), those not receiving RT (adjusted HR 1.23, p=0.03), patients 65 years or older, and males. Conclusions: This population based study identified older patients as less likely to receive RT and females as more likely to receive RT. Survival analysis identified blacks, males, older patients, and those not receiving RT as having lower rates of survival.

Abstract Introduction The number of elderly patients with primary central nervous system malignant lymphoma(EL-PCNSL) has been increasing. However, due to their poor pre-treatment Karnofsky Performance Status(KPS) and many comorbidities, it is possible that sufficient treatment has not been performed. We therefore conducted a retrospective cohort study to evaluate risk factors associated with a poor prognosis of the Real-World status of EL-PCNSL in the Tohoku Brain Tumor Study Group. Methods Patients aged ≥ 71 years with PCNSL were enrolled from 8 centers. Univariate analysis was performed by the log-rank test. A Cox proportional hazards model was used for multivariate analysis. Results Three of total 142 cases received best supportive care(BSC) from the beginning. Treatment was given to 30 cases without a pathological diagnosis, 3 cases with a cerebrospinal fluid diagnosis, and 100 cases with CD20-positive DLBCL diagnosis. Total 133 cases(median age 76 years) were included. The median pre-treatment KPS was 50%. There were 117(88.0%) patients with 213 pre-treatment comorbidities(1.8 comorbidities per patient). PFS and OS were 16 months and 24 months, respectively. Risk factors associated with poor prognosis on Cox proportional hazards model were pre-treatment cardiovascular disease and central nervous system disease comorbidities, post-treatment pneumonia and other infections, and the absence of radiation or chemotherapy. Conclusions EL-PCNSL was actively treated and BSC was only a few. Pre-treatment comorbidities and post-treatment complications would influence the prognosis. Radiation and chemotherapy were found to be effective, but no conclusions could be drawn regarding the content of chemotherapy and whether additional radiation therapy should be used.

ObjectiveLeft ventricular (LV) geometry change is an independent predictor for cardiovascular disease. However, data are equivocal on the association of echocardiographic parameters of LV geometry with incident hypertension. Thus, we were to investigate the risk of hypertension according to the baseline echocardiographic parameters of LV geometry.MethodsStudy participants were 12 562 Koreans without hypertension who received echocardiography as an item of health check-up. They were divided into normotensive or prehypertensive group according to baseline blood pressure. In each group, study subjects were classified by quintiles of baseline echocardiographic parameters including left ventricular mass index (LVMI), relative wall thickness (RWT), interventricular septal thickness (IVST), posterior wall thickness (PWT) and IVST plus PWT and followed up for 5 years. Cox proportional hazards model was used in calculating adjusted HRs and their 95% CI for hypertension according to each quintile group. Area under the curve (AUC) analysis (AUC [95% CI]) was performed to compare the predictability of LVMI, RWT, IVST, PWT, IVST plus PWT for hypertension.ResultsPrehypertensive group had the worse clinical and echocardiographic parameters in baseline analysis than normotensive group. The risk of hypertension significantly increased proportionally to baseline LVMI, RWT, IVST, PWI and IVST plus PWT above specific quintile levels, which was identified in both normotensive and prehypertensive group. In AUC analysis, IVST, PWT and IVST plus PWT showed a significantly increased AUC, compared with LVMI.ConclusionLV geometry change was significantly associated with the increased risk for hypertension in non-hypertensive individuals.
