Gleason score and tumor laterality in radical prostatectomy and transrectal ultrasound-guided biopsy of the prostate： a comparative study

引用

Asian Journal of andrology 2015年第5期17卷 815-820,I0009-I0010页

We aimed to compare Gleason score and tumor laterality between transrectal ultrasound-guided biopsy of the prostate （TRUSBX） and radical prostatectomy （RP）. Some factors that could cause a discrepancy in results between these two procedures were also evaluated. Among the 318 cases reviewed, 191 cases were selected for inclusion in this comparative Study, We divided the patients into two groups using the Gleason score： an intermediate/high-grade group （≥7） and a low-grade group （〈6）. Exploratory analyses were conducted for comparisons between groups. We also performed comparisons between TRUSBX and RP for tumor laterality. TRUSBX overestimated 6% and underestimated 24% cases in comparison with RP for Gleason score, and overestimated 2.6% and underestimated 46% cases compared with RP for tumor laterality. Biopsy specimens were slightly smaller in TRUSBX cases with underestimated tumor laterality （P〈 0.05）, and no relationship between the biopsy specimen size and underestimated Gleason score in TRUSBX was found. Prostatic volume showed no statistical correlation with the likelihood of under or overestimation （P 〉 0.05）. Thus, our study showed that TRUSBX has a high likelihood of underestimating both the Gleason score and tumor laterality in prostate cancer （PCa）. The size of the fragment appears to be an important factor influencing the likelihood of laterality underestimation and Gleason score overestimation via TRUSBX. Due to the high likelihood of underestimation of the Gleason score and tumor laterality by 12-core prostate biopsy, we conclude that this type of biopsy should not be used alone to guide therapy in Pca.

AIM： To evaluate the classification and severity of Crohn＇s disease in different racial groups. METHODS： Patients with Crohn＇s disease from the outpatient clinic of the University Hospital Prof. Edgard Santos were enrolled in the study. This hospital is a reference centre for inflammatory bowel disease. Race was determined using self-identification. The Vienna＇s classification was applied for all subjects. The severity of Crohn＇s disease was determined according to the number of surgical procedures, hospital admissions in the last year and treatment with steroids and immunosuppressors. Statistical analysis was calculated using t test for means,χ^2 or F for proportions. A P value 〈 0.05 was considered to be significant. RESULTS： Sixty-five patients were enrolled. Non-white patients were more frequently diagnosed with Crohn＇s disease in the age less than 40 years than white patients. The behaviour of disease was similar in both groups with a high frequency of the penetrating form. There was a tendency for non-white patients to have a greater frequency of hospital admissions in the last year compared to white subjects. Non-whites also had a higher rate of colonic and upper gastrointestinal involvement, and were also more frequently on treatment with immunossupressors than white patients although this difference was not statistically significant. CONCLUSION： Non-white patients with Crohn＇s disease had an earlier diagnosis and appeared to have had a more severe disease Dresentation than white patients.

Intake,digestibility and nitrogen utilization in cattle fed tropical forage and supplemented with protein in the rumen,abomasum,or both

引用

Journal of Animal Science and Biotechnology 2016年第4期7卷 544-553页

作者： Luana Marta de Almeida Rufino Edenio Detmann Daianyíris Gomes William Lima Santiago dos reis Erick Darlisson Batista Sebastiao de Campos Valadares Filho Mário Fonseca Paulino Department of Animal Science Universidade Federal de Viaosa Department of Animal Science Universidade Federal Rural da Amaznia

Background： There is little information in the tropics with regard the comparative understanding of how an increased nitrogen supply in the rumen or in the intestines affects efficiency of nitrogen utilization in cattle. This study evaluated the effects of supplementation with nitrogenous compounds in the rumen, abomasum, or both on intake, digestibility and the characteristics of nitrogen utilization in cattle fed tropical forage. Four rumen- and abomasum-fistulated Nellore bulls （227 ± 11 kg） were used. Four treatments were evaluated： control, ruminal supplementation （230 g/d of supplemental protein in the rumen）, abomasal supplementation （230 g/d of supplemental protein in the abomasum）, and ruminal and abomasal supplementation （115 g/d protein in both the rumen and the abomasum）. The basal forage diet consisted of Tifton 85 hay with a crude protein （CP） level of 78.4 g/kg dry matter. Casein was used as a supplement. The experiment was conducted using a 4 x 4 Latin square. Results： There were no differences between the treatments （P 〉 0.10） with regard to forage intake. The intake and tota digestibility of CP increased （P 〈 0.01） with supplementation. The nitrogen balance in the body increased （P 〈 0.01） and muscle protein mobilization decreased （P 〈 0.01） with supplementation, regardless of the supplementation site. The efficiency of nitrogen utilization did not differ among the treatments （P 〉 0.10）. Conclusions： The supplementation of cattle fed tropical forage with protein in the rumen, abomasum, or both similarly increased the nitrogen accretion in animal, which reflects improvements on nitrogen status in animal body.
