A total of 180 weaned piglets (Landrace × Yorkshire × Duroc) were randomly allotted to three treatments on the basis of body weight (BW). There were six replicate pens in each treatment with 10 piglets per pen. Dietary treatments were corn-soybean meal-based basal diet supplemented with 0 (control), 2.5, and 5.0% citrus pulp, fish by-product, and B. subtilis fermentation biomass. The isocaloric and isoproteineous experimental diets were fed in mash form in two phases (d 0 ~ 14, phase I and d 15 ~ 28, phase II). Dietary treatments had significant linear effects on gain to feed ratio (G:F) in all periods, whereas significant linear effects on ATTD of dry matter (DM), gross energy (GE), and ash were only observed in phase I. Piglets fed diet supplemented with 5.0% citrus pulp, fish by-product, and B. subtilis fermentation biomass showed greater (p < 0.05) G:F (phase I, phase II, and overall) as well as ATTD of DM, GE, and ash (phase I) than pigs fed control diet. Dietary treatments also had significant linear effects on total anaerobic bacteria populations by d 14 and 28. In addition, piglets fed diet supplemented with 5.0% citrus pulp, fish by-product and B. subtilis fermentation biomass showed greater (p < 0.05) fecal total anaerobic bacteria populations (d 14 and 28) than pigs fed control diet. Dietary treatments had no significant effects (linear or quadratic) on average daily gain (ADG), average dial feed intake (ADFI; phase I, phase II, and overall), or fecal populations of Bifidobacterium spp., Clostridium spp., and coliforms (d 14 and 28). These results indicate that dietary supplementation with 5.0% citrus pulp, fish by-product, and B. subtilis fermentation biomass has the potential to improve the feed efficiency, nutrient digestibility, and fecal microflora of weanling pigs.

[Show abstract][Hide abstract] ABSTRACT: An experiment was conducted to determine the effects of origins of soybean meal (SBM) on growth performance, nutrients and energy retention and fecal microflora in broilers. The SBM originating from Korea, Brazil and India were used. A total of 480 broiler chicks (average initial BW, 41.8 g) were randomly allotted to 6 treatments. Each treatment had 4 replicate pens with 20 chicks per pen. Birds were fed diets containing SBM originated from Korea (domestic SBM), Brazil or India (imported SBM) and the diets were based on the total amino acid (TAA) or true digestible amino acid (TDAA). Experimental diets were fed in two phases, starter (d 0~21) and finisher (d 22~35). The overall weight gain, feed intake and FCR were better (P

[Show abstract][Hide abstract] ABSTRACT: OBJECTIVE: To present our long-term follow-up data to investigate whether cigarette smoking is associated with the prognosis of bladder cancer after radical cystectomy. Despite the close link between cigarette smoking and the development of bladder cancer, little is known about the influence of cigarette smoking on the bladder cancer prognosis after radical cystectomy. MATERIALS AND METHODS: The cigarette smoking status of 602 patients who had undergone radical cystectomy for bladder cancer was determined using questionnaires completed before surgery. The effect of cigarette smoking on recurrence-free survival, cancer-specific survival, and overall survival was determined. RESULTS: Of the 340 patients with a smoking history, 159 were current smokers. The smokers were younger (P = .001) and more likely to be male (P = .001) than were the nonsmokers. The 5-year recurrence-free survival rate of the smokers and nonsmokers was 62.1% and 56.8% (P = .182), the 5-year cancer-specific survival rate was 67.3%, 63.9% (P = .436), and the 5-year overall survival rate was 63.0% and 58.8% (P = .309), respectively. Multivariate analysis revealed that smoking was not an independent predictor of recurrence-free survival or cancer-specific survival. After adjusting for other prognostic variables, cigarette smoking status (non-, ex-, or current smoker), cumulative exposure, and years from smoking cessation were not associated with cancer-specific survival (P = .378, P = .827, and P = .876, respectively). CONCLUSION: The results of the present study found no association between cigarette smoking and the prognosis of bladder cancer after radical cystectomy.
[Show abstract][Hide abstract] ABSTRACT: Study Type - Prognosis (case series) Level of Evidence 4 What's known on the subject? and What does the study add? In patients with pRCC, the presence of venous tumour thrombus is known to be a predictor of poorer outcomes. However, a paucity of data is available regarding the prognostic significance of histology in patients with RCC and IVC thrombus. In our series, we found that patients with type II pRCC had significantly poorer outcomes when compared to those with cRCC. Although the lack of effective treatment for patients with metastatic pRCC may have contributed to these adverse outcomes, type II papillary histology was independent predictor not only of CSS but also of RFS. OBJECTIVE: • To analyze the prognostic impact of papillary histology on oncological outcomes in patients with renal cell carcinoma (RCC) and inferior vena cava (IVC) thrombus. PATIENTS AND METHODS: • We reviewed the medical records of 74 patients who underwent radical nephrectomy and IVC thrombectomy between 1990 and 2010 for clear cell or papillary RCC. • We compared the clinicopathological features and clinical outcomes of 62 patients with clear cell RCC (cRCC) and 12 with papillary RCC (pRCC). • All cases of pRCC were subdivided into type I or type II. • The prognostic role of papillary histology on recurrence-free survival (RFS) and cancer-specific survival (CSS) was estimated using Cox's regression models. RESULTS: • Upon reclassification of the pRCC subtype, all 12 patients with pRCC had type II tumours. • Patients with type II pRCC were significantly younger (P = 0.028) and were more probably women (P = 0.025) than those with cRCC • The 2- and 5-year CSS rates were 81.1% and 53.6% in cRCC patients, and 28.1% and 0% in type II pRCC patients, respectively. All eight patients with non-metastatic type II pRCC developed disease recurrence at a median interval of 6 months after surgery, whereas 25 of 44 (56.8%) patients with non-metastatic cRCC experienced such recurrence at a median interval of 10 months after surgery. • Patients with type II pRCC showed significantly lower CSS (P < 0.001) and RFS (P = 0.002) than those with cRCC. • On multivariate analysis, type II papillary histology was an independent predictor of CSS (hazard ratio, 3.73; P = 0.003) and RFS (hazard ratio, 3.15; P = 0.015). CONCLUSIONS: • Type II papillary histology appears to be predominant in cases of pRCC with IVC thrombus. • Patients with type II pRCC who presented with IVC thrombus had significantly worse outcomes than those with cRCC, and histology is an important prognostic factor in patients with RCC and IVC thrombus.
[Show abstract][Hide abstract] ABSTRACT: OBJECTIVES: To evaluate the risk factors and prognosis of muscle-invasive bladder cancer (MIBC) developing after nephroureterectomy for upper urinary tract urothelial cell carcinoma (UUT-UC). MATERIALS AND METHODS: We reviewed the medical records of 422 patients who underwent nephroureterectomy for UUT-UC between 1990 and 2010, and identified 173 (40.9%) with intravesical recurrence and 28 (6.6%) with MIBC. We evaluated the clinicopathologic features, risk factors, and cancer-specific survival (CSS) using the Kaplan-Meier method and the Cox proportional hazards regression models. RESULTS: The median intervals from nephroureterectomy to intravesical recurrence and the development of MIBC were 8 and 17 months, respectively. On multivariate analysis, the pathologic stage (≥pT3 vs. Ta/T1, HR 5.03, P = 0.001) and ureteral tumor location (HR 2.79, P = 0.011) were independent risk factors for the development of MIBC, whereas a history of previous or concomitant bladder tumor was the only significant risk factor for intravesical recurrence. The probability of developing MIBC 5 years after nephroureterectomy was 12.6% in patients with 1 risk factor and 20.6% in patients with both risk factors. Patients with MIBC had significantly worse CSS than those without MIBC (P = 0.004), whereas CSS rates were similar in patients with and without intravesical recurrence (P = 0.593). However, stratification analysis for matching pathology revealed that CSS rates were not significantly different in patients with pT2 or higher stage of UUT-UC. CONCLUSIONS: Approximately 5% of the patients developed MIBC after nephroureterectomy with a median interval of 17 months. Patients with advanced pathologic stage (≥pT3) and a ureteral tumor location are at increased risk of developing MIBC after nephroureterectomy.
[Show abstract][Hide abstract] ABSTRACT: To evaluate the impact of surgical waiting time (SWT) on outcomes of patients who underwent radical nephrectomy for stage II or higher renal cell carcinoma (RCC).
Of the 1,732 patients who underwent surgery for RCC between 1989 and 2007, medical records of 319 with clinical stage II or higher RCC without distant metastases were retrospectively reviewed. Ten patients with SWT greater than 3 months were excluded from analysis, and we compared pathological upstaging and survival rates between patients with SWT <1 month (234/319, 73.3 %) and 1-3 months (75/319, 23.5 %).
Clinicopathological characteristics between two groups were not different except the presence of symptom. The pathological upstaging was higher in patients with SWT of 1-3 months but statistically not significant. SWT of 1-3 months was not an independent predictor of pathological upstaging, recurrence-free survival (RFS; p = 0.896), or cancer-specific survival (CSS; p = 0.737). On subgroup analysis by TNM stage (cT2NxcM0 and cT3-4NxcM0), SWT of 1-3 months was not an independent predictor of pathological upstaging and was not associated with RFS or CSS. SWT, treated as a continuous variable, was also not an independent predictor of outcome in any subgroup. Similar results were found in symptomatic patients.
The outcomes of patients with prolonged SWT did not differ from those of most patients who underwent nephrectomy within 1 month. In patients with stage II or higher RCC who underwent nephrectomy within 3 months after diagnosis, prolonged SWT was not an independent predictor of pathological upstaging, RFS, or CSS.
