⋄ Objectives Comparisons of survival in patients on peritoneal dialysis (PD) and on hemodialysis (HD) have been conducted in many Western countries, but publications on this subject in Asian populations are scarce. The present study estimated the survival and the relative mortality hazard for HD and PD patients in Taiwan. ⋄ Methods Incident end-stage renal disease patients reported to the Taiwan Renal Registry during 1995 – 2002 were included in the study. Patients had to be 20 years of age or older and had to have survived for the first 90 days on dialysis. A total of 45 820 incident HD and 2809 incident PD patients formed the study population. Patients on PD were treated mainly with traditional glucose-based solutions. Using an intent-to-treat analysis, the Cox proportional hazards (CPH) model was applied to identify the factors that predict survival by treatment modality. Subgroup analyses were conducted by stratifying patients according to sex, comorbidity, age, and diabetes status. Kaplan–Meier estimates were used to explore the survival of HD and PD patients. Adjustments were implemented using the CPH model. ⋄ Results The overall 1-year, 2-year, 3-year, 5-year and 10-year survival rates for PD patients were 89.8%, 77.6%, 67.6%, 55.5%, and 35% respectively. The equivalent survival rates for HD patients were 87.5%, 76.6%, 68.1%, 54.3%, and 33.8%. The differences were not statistically significant ( p = 0.125). The CPH analysis stratified by diabetes status and age revealed that PD patients 55 years of age or younger and nondiabetic had a lower mortality ratio (MR) of 0.94. But the MR increased to 1.31 for nondiabetic patients older than 55. The MR for PD versus HD further increased to 1.72 for diabetic patients 55 years of age or younger, and to 1.99 for diabetic patients older than 55. ⋄ Conclusions After adjusting for both demographic and clinical case-mix differences, PD and HD patients were observed to have similar long-term survival. Subgroup analyses revealed that, among diabetic patients and patients older than 55, those on HD experienced better survival than did those on PD.

Predictors Of Mortality

Our objective was to examine the influence of various demographic, clinical, and enrollment biochemical variables on the long-term survival of continuous ambulatory peritoneal dialysis (CAPD) patients. This was a prospective cohort study investigating the relationship between demographics and enrollment biochemical markers and mortality in CAPD patients in a CAPD unit in a large tertiary care teaching hospital. One hundred and sixtynine patients in the CAPD program were enrolled between 1989 and 1994, and were followed up to 60 months. Independent predictors of mortality determined by Cox proportional hazards model included age, diabetes, serum albumin and creatinine. Enrollment level of serum albumin, and creatinine can predict mortality in CAPD patients up to 60 months. Markers of visceral and somatic nutrition at enrollment are important predictors of mortality in CAPD patients up to five years.

Pancreatic Neuroendocrine Neoplasm

Background. Pancreatic neuroendocrine neoplasm (pNEN), with the lowest 5-year survival rates in neuroendocrine tumors (NETs), exerts great threat to human health. Because large-scale population research aimed at pNEN is rare, we aimed to explore the tendencies and differences of changes in incidences and survival rates of pNEN in each decade from 1987 to 2016 and evaluate the impacts of age, sex, race, socioeconomic status (SES), and grade. Methods. Data on pNEN cases from 1987 to 2016 were extracted from the Surveillance, Epidemiology, and End Results Program (SEER) database. Kaplan–Meier, Cox proportional hazards regression analyses, and relative survival rates (RSRs) were used to identify risk factors for pNEN. Results. The incidence and survival duration of pNEN increase every decade due to medical developments. The disparities of long-term survival in different age, sex, and grade groups expanded over time while that in race and SES groups narrowed. Older age and higher grade are independent risk factors for poorer survival. Females have lower incidence and longer survival than males. Prognosis of Black patients and poor (medium and high poverty) patients improved. Conclusions. This study depicted changes in incidence and survival rates of pNEN over the past three decades and evaluated potential risk factors related to pNEN, benefiting future prediction of vulnerable and clinical options.

Family History Of Diabetes

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.

♦ Objective Higher than normal body mass index (BMI) is associated with an increased risk of death in the general population. We examined the effect of higher than normal BMI on patient and technique survival in peritoneal dialysis patients (PD), controlling for comorbidity, initial albumin, dialysate-to-plasma ratio of creatinine (D/PCr), and initial urea clearance (Kt/V). ♦ Design Registry database. ♦ Settings Four dialysis centers. ♦ Patients Incident PD patients. ♦ Methods All data were collected prospectively. Demographics, BMI, serum albumin, D/PCr, and comorbidity using the Charlson Comorbidity Index (CCI) were determined at the start of PD. 104 patients with a high BMI (> 27) were matched to a control group of 104 patients with normal BMI (20 – 27) for age, gender, presence of diabetes, and CCI. Patient and technique survival were compared using Cox proportional hazards model. ♦ Main Outcome Measures Patient and technique survival. ♦ Results The groups were of similar age (56.1 vs 56.7 years), sex (60% males in both groups), race (Caucasian 80% vs 86%), presence of diabetes (40% vs 37%), CCI score (5.4 in both groups), initial albumin (3.6 vs 3.5 g/dL), and D/PCr (0.65 in both groups). Kaplan–Meier survival analysis showed similar 2-year patient survival between large BMI (> 27) and control (20 – 27) groups (76.6% vs 76.1%). Two-year technique survival was also similar between the two groups (59.7% vs 66.8%). With Cox proportional hazards analysis, BMI was not a predictor of patient mortality or technique survival when controlling for initial albumin, D/PCr, and initial Kt/V. ♦ Conclusions We conclude that a BMI above normal is not associated with any increased or decreased risk of death in patients on PD for 2 years.

Intent To Treat

To evaluate the mortality of continuous ambulatory peritoneal dialysis (CAPD) patients relative to hemodialysis (HD) patients, all Michigan residents 20 to 59 yr of age who initiated therapy for ESRD during the 1980s (N = 4,288) were studied. The study population was stratified by primary renal diagnosis (glomerulonephritis, hypertension, diabetes, other), and analyses were conducted within each group by Cox proportional hazards methods controlling for age, race, sex, and year in which chronic dialysis was initiated. Intent-to-treat (ITT) and treatment history (RxHx) censoring criteria were used. For patients with hypertension or other reported causes of ESRD, there was no significant difference in CAPD and HD patient mortality (relative risk (RR) = 0.99 and 1.05, respectively). In the ITT analysis, both glomerulonephritic (RR = 0.73; P = 0.10) and diabetic patients using CAPD experienced mortality rates lower than their HD counterparts. Among diabetics, this difference ranged from a RR of 0.40 to 0.70, being lowest for younger diabetics and statistically significant (P < or = 0.05) for ages 20 to 52 yr. Evaluation of mortality trends showed a significant (P < 0.01) decrease in diabetic CAPD mortality rates during the decade, whereas diabetic HD mortality rates increased (P = 0.06). Among diabetics, men had higher mortality rates than women (ITT--RxHx; RR = 1.22 to 1.27; P < 0.001) and white patients had higher mortality rates than black patients (ITT--RxHx, RR = 1.34 to 1.44; P < 0.001). Differences in mortality by sex and race were not found among nondiabetics, but mortality did increase significantly with age in all groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Patient Questionnaires

Our objective was to analyze the survival of diabetic patients on renal replacement therapy and to compare their survival on extracorporeal and on peritoneal dialysis. All data regarding diabetic patients admitted to dialysis between 1 January 1983 and 31 December 1993 were collected by means of individual patient questionnaires sent to all of the 44 regional Renal Units (100% answers) of Lombardy, Italy. Cox proportional hazards model, stepwise procedure, was applied in order to select the covariates significantly associated with survival. Age (at baseline), sex, type of diabetes, initial modality of treatment (hemodialysis or peritoneal dialysis), and initial clinical risk factors (malignancies, serious heart disease, vascular disease, cirrhosis of the liver, cachexia) were considered. Descriptive analysis of survival was performed using the Kaplan-Meier technique. The survival of all diabetic patients (895) was 86.5% at one year, 52% at three years, an d 34% at five years. The main causes of the 488 deaths of diabetic patients were cardiovascular diseases (56%), cachexia (18%), and infections (11%). The relative death risk of patients on peritoneal dialysis versus those on hemodialysis, after taking into account the main comorbid conditions, did not significantly differ from 1, as estimated by the Cox proportional hazards regression model. Five-year survival of diabetic patients was 34%, and no differences were found between peritoneal dialysis and hemodialysis as far as mortality is concerned.

Objective To explore the effect of glycated hemoglobin (HbA1c) and albumin-corrected glycated serum proteins (Alb-GSP) on the mortality of diabetic patients receiving continuous peritoneal dialysis (PD). Methods In this single-center retrospective cohort study, incident diabetic PD patients from January 1, 2006, to December 31, 2010, were recruited, and followed up until December 31, 2011. The effect of HbA1c and Alb-GSP on mortality was evaluated by Cox proportional hazards models. Results A total of 200 patients (60% male, mean age 60.3 ± 10.6 years) with a mean follow-up of 29.0 months (range: 4.3 - 71.5 months) were recruited. Sixty-four patients died during the follow-up period, of whom 21 died of cardiovascular disease (CVD). Mean values for HbA1c, GSP and Alb-GSP were 6.7% (range: 4.1 - 12.5%), 202 μmol/L (range: 69 - 459 μmol/L), and 5.78 μmol/g (range: 2.16 - 14.98 μmol/g), respectively. The concentrations of GSP and Alb-GSP were closely correlated with HbA1c ( r = 0.41, p < 0.001 and r = 0.45, p < 0.001, respectively). In multivariate Cox proportional hazards models, patients with HbA1c ≥8% were associated with increased risk of all-cause mortality (hazard ratio [HR] = 2.29, 95% confidence interval [CI]: 1.06 - 4.96, p = 0.04), but no increased mortality in patients with 6.0% ≤ HbA1c ≤ 7.9%. Patients with Alb-GSP ≤ 4.50 μmol/g had increased all-cause and non-cardiovascular mortality (HR = 2.42, 95% CI: 1.13 - 5.19, p = 0.02; and HR = 2.98, 95% CI: 1.05 - 8.48, p = 0.04 respectively). Conclusions Increased HbA1c and decreased Alb-GSP may be associated with poorer survival in diabetic PD patients, with a non-significant trend observed for poorer survival with the highest level of Alb-GSP.

Summary: Background: The aim of this study was to assess the prognostic interaction between age and sex on peri-operative and follow-up outcomes following elective carotid endarterectomy (CEA) for asymptomatic and symptomatic carotid stenosis. Patients and methods: A retrospective review of all patients admitted to a single vascular unit who underwent elective CEA between January, 2015 and December, 2019 was performed. The primary endpoints of the study were overall survival (from index operation) and cumulative stroke rate at thirty days. Results: A total of 383 consecutive patients were included in this study; of these 254 (66.4%) were males. At baseline, males were younger (mean age 73.4±11 vs. 76.3±10 years, p=.01) and with lower proportion of octogenarians (20.4% vs. 28.7%, p=.05). The rate of stroke in symptomatic and asymptomatic patients (males vs. females) were as follows: a) whole cohort 1.9% vs. 2% (p=1.00) and 2.7% vs. 1.3% (p=.66), respectively; b) ≥80 years old 3.7% vs. 0% (p=1.00) and 4% vs. 5.9% (p=1.00), respectively; c) <80 years old 1.2% vs. 3.3% (p=.47) and 2.5% vs. 0% (p=.55), respectively. The 3-year survival estimates were significantly lower for males (84% vs. 92%, p=.03). After stratification by age groups, males maintained inferior survival rates in the strata aged <80 years (85% vs. 97%, p=.005), while no differences were seen in the strata aged ≥80 years (82% vs. 79%, p=.92). Using multivariate Cox proportional hazards, age (HR: 2.1, 95% CI: 1.29–3.3, p=.002) and male gender (HR: 2.5, 95% CI: 1.16–5.5, p=.02) were associated with increased hazards of all-cause mortality. Conclusions: In this study of elective CEA for asymptomatic and symptomatic carotid stenosis, similar peri-operative neurologic outcomes were found in both males and females irrespective of age. Despite being usually older, females have superior long-term survival rates.

<b><i>Introduction:</i></b> Immune checkpoint inhibitors (ICI) are the new standard therapy in patients with metastatic NSCLC (mNSCLC). Metformin, previously associated with improved chemotherapy efficacy in diabetic and nondiabetic cancer patients, was recently associated with increased ICI efficacy. In this study, we aimed to explore the correlations between diabetes mellitus (DM), metformin use, and benefit from ICI in mNSCLC patients. <b><i>Methods:</i></b> All mNSCLC patients treated with ICI in our center between February 2015 and April 2018 were identified. Demographic and clinical data were extracted retrospectively. Cox proportional hazards regression, <i>t</i> tests, and χ<sup>2</sup> tests were employed to evaluate associations of progression-free survival (PFS), overall survival (OS), overall response rate (ORR), and disease control rate (DCR), with DM status, metformin use, and HbA1c levels, as appropriate. <b><i>Results:</i></b> Of 249 mNSCLC patients treated with ICI, 57 (22.8%) had DM. Thirty-seven (64.9% of all diabetic patients) patients were treated with metformin. A significant negative correlation of DM with PFS and OS was demonstrated (HR 1.5 [1.01–2.06], <i>p</i> = 0.011, and HR 1.5 [1.08–2.08], <i>p</i> = 0.017, respectively). Metformin exposure had no significant correlation with PFS or OS in diabetic mNSCLC patients (HR 1.08 [0.61–1.93], <i>p</i> = 0.79, and HR 1.29 [0.69–2.39], <i>p</i> = 0.42, respectively). There were no differences between groups with respect to ORR and DCR. <b><i>Conclusion:</i></b> Our data show a potential negative relationship between DM and ICI efficacy in mNSCLC patients. In contrast to reports with chemotherapy, we found no positive relationship between metformin use and ICI therapy in diabetic patients with mNSCLC. Further studies are needed to evaluate the effect of metformin in nondiabetic mNSCLC patients.

Abstract Purpose Colorectal cancer revealed over the last decades a remarkable shift with an increasing proportion of a right- compared to a left-sided tumor location. In the current study, we aimed to disclose clinicopathological differences between right- and left-sided colon cancer (rCC and lCC) with respect to mortality and outcome predictors. Methods In total, 417 patients with colon cancer stage I–IV were analyzed in the present retrospective single-center study. Survival rates were assessed using the Kaplan–Meier method and uni/multivariate analyses were performed with a Cox proportional hazards regression model. Results Our study showed no significant difference of the overall survival between rCC and lCC stage I–IV (p = 0.354). Multivariate analysis revealed in the rCC cohort the worst outcome for ASA (American Society of Anesthesiologists) score IV patients (hazard ratio [HR]: 16.0; CI 95%: 2.1–123.5), CEA (carcinoembryonic antigen) blood level > 100 µg/l (HR: 3.3; CI 95%: 1.2–9.0), increased lymph node ratio of 0.6–1.0 (HR: 5.3; CI 95%: 1.7–16.1), and grade 4 tumors (G4) (HR: 120.6; CI 95%: 6.7–2179.6) whereas in the lCC population, ASA score IV (HR: 8.9; CI 95%: 0.9–91.9), CEA blood level 20.1–100 µg/l (HR: 5.4; CI 95%: 2.4–12.4), conversion to laparotomy (HR: 14.1; CI 95%: 4.0–49.0), and severe surgical complications (Clavien-Dindo III–IV) (HR: 2.9; CI 95%: 1.5–5.5) were identified as predictors of a diminished overall survival. Conclusion Laterality disclosed no significant effect on the overall prognosis of colon cancer patients. However, group differences and distinct survival predictors could be identified in rCC and lCC patients.
