Effect of a soy protein diet on serum lipids of renal transplant patients.

OBJECTIVE: The aim of the present study was to evaluate the effect of a soy-protein diet on plasma lipid levels of renal transplant recipients with moderate hypercholesterolemia. DESIGN: Dietary intervention case-control observational study. SETTING: Renal transplantation outpatient clinic. PATIENTS: Fifteen stable patients who had renal transplantation (serum creatinine < 2 mg/dL) with moderate hypercholesterolemia (low-density lipoprotein [LDL] cholesterol > 140 mg/dL). INTERVENTION: After a baseline dietary interview, dietary counseling was given individually with the goal of substituting 25 g of animal protein with 25 g of soy protein for a 5-week period, using commercially available soy foods, according to each patient's own preference.Main outcome measures Before and after the soy-diet period, plasma lipid profiles including total, LDL, and high-density lipoprotein (HDL) cholesterol, triglycerides, apolipoprotein A1 and B were determined. Protein catabolic rate was assumed as a measure of dietary protein intake. RESULTS: Two patients dropped out. After the soy diet, total cholesterol (254 +/- 22 to 231 +/- 31 mg/dL, P <.05) and LDL cholesterol (165 +/- 20 versus 143 +/- 20 mg/dL, P <.01) decreased significantly. No significant changes were observed regarding HDL cholesterol and triglycerides. Dietary protein intake did not differ at baseline (73.2 +/- 22.9 g/day) and during the soy diet (72.6 +/- 15.6 g/day), when the reported actual soy protein intake resulted 26 +/- 8 g/day. CONCLUSIONS: This study shows that soy proteins given as part of the daily protein intake have beneficial effects on serum LDL cholesterol levels of renal transplant recipients with moderate hypercholesterolemia. Soy proteins could be of use in the nutritional management of renal transplant recipients.     

The SmartTarget Biopsy Trial: A Prospective,Within-person Randomised,Blinded Trial Comparing the Accuracy of Visual-registration and Magnetic Resonance Imaging/Ultrasound Image-fusion Targeted Biopsies for Prostate Cancer Risk Stratification

Background

Multiparametric magnetic resonance imaging (mpMRI)-targeted prostate biopsies can improve detection of clinically significant prostate cancer and decrease the overdetection of insignificant cancers. It is unknown whether visual-registration targeting is sufficient or augmentation with image-fusion software is needed.

Sacrocolpopexy for posthysterectomy vaginal vault prolapse: long-term follow-up

Introduction and hypothesis

Abdominal sacrocolpopexy (ASC) is considered the gold standard for vaginal vault prolapse (VVP) repair. Our aim was to evaluate the long-term durability of its anatomic and functional results.

Methods

This was a prospective series of women undergoing ASC for symptomatic VVP stage III or IV according to the Pelvic Organ Prolapse Quantification (POP-Q) system. All patients were followed up every 3 months for the first postoperative year and then annually for anatomical and functional outcomes and complications. Only patients with at least 48 months of follow-up were included in this report. Anatomic success was defined as postoperative prolapse stage 0 or I. Statistical analysis was performed using the nonparametric Mann–Whitney U test for the analysis of continuous variables and the McNemar and χ² test for categorical data.

Results

Sixty-seven women were followed up for a median of 60 months (range 48–144). Anatomical success was 100 % for apical prolapse and 94 and 91 % for anterior and posterior compartments, respectively. There were only four (6 %) and six (9 %) cases of stage II persistence or recurrence for the anterior and posterior compartments, respectively, which did not require reoperation. There was no vault prolapse recurrence. Voiding and storage urinary and sexual symptoms were significantly improved. Anorectal dysfunction symptoms persisted in 40.6 % of patients with these symptoms preoperatively and developed de novo in 22.8 % of patients without them preoperatively. Three mesh exposures were noted. Sixty-three patients (94 %) were extremely or very much improved with sacrocolpopexy according to the Patient Global Impression–Improvement scale.

Conclusions

Our data confirm the long-term durability of vaginal vault prolapse repair with ASC.

     

The antimanic-like effect of tamoxifen: Behavioural comparison with other PKC-inhibiting and antiestrogenic drugs

Protein kinase C (PKC) is an important cellular target for mood stabilizers such as lithium and valproate, and tamoxifen, an antiestrogenic drug with PKC inhibition activity, also demonstrates an antimanic effect. Thus, the aim of the present study was to evaluate whether the antimanic effect of tamoxifen is mediated through the PKC inhibitory and/or the antiestrogenic action(s) of the drug. In the present study, the effects of tamoxifen, chelerythrine (a PKC inhibitor) and medroxyprogesterone (an antiestrogenic drug) were investigated in amphetamine-induced hyperlocomotion of mice, an animal model of a manic state. Lithium carbonate (100 and 150mg/kg, i.p.), tamoxifen (1.0mg/kg, i.p.) and chelerythrine (1μg/site, i.c.v.) completely blocked the amphetamine-induced hyperlocomotion. However, while the intermediate medroxyprogesterone dose (3.0mg/kg, i.p.) partially reduced the amphetamine-induced hyperlocomotion, lower (1.0mg/g) and higher (6.0mg/kg) doses produced no effect. Our results indicate a major role for PKC inhibition in the antimanic-like effect of tamoxifen, although its antiestrogenic action may also contribute to this effect.
