The nano-micellar curcumin improves International Prostate Symptoms Score (IPSS) in patients with benign prostatic hyperplasia: a randomized clinical trial.

PURPOSE: Benign prostatic hyperplasia (BPH) is the main prevalent disorder in men over forty years, usually revealing itself with lower urinary tract symptoms. Despite the existence of different treatments, the incidence of BPH is increasing, so further studies for better management are a necessity. This research was designed to assay the effectiveness of nano-micellar curcumin on biomedical indicators of patients with BPH. METHODS: The present research was a double-blind, randomized, and placebo-controlled trial that enrolled fifty-two patients with BPH between June 2021 and December 2021. Participants were randomized to receive 160 mg/d nano-micellar curcumin (n = 26) or placebo (n = 26) as soft gel during 3 months. Primary end point was changes in International Prostate Symptoms Score (IPSS). Data gathering was occurred using a standard inquiry form and measuring other biomedical parameters based on routine laboratory techniques. To compare the distribution of demographics and covariates, independent t-test and Chi-square were used. RESULTS: Nano-micellar curcumin had significant effect on IPSS (p value: 0.010), low effect on high-sensitive C-reactive protein (hs-CRP) (p value: 0.032), and low to intermediate effect on malondialdehyde (MDA) (p value: 0.014) level as secondary end points after the intervention. The effect of nano-micellar curcumin on other parameters was negligible. CONCLUSION: Overall, this trial indicated 3-month intake of nano-micellar curcumin had considerable effects on IPSS as the most common clinical symptom and also two biomedical parameters including serum hs-CRP and MDA.

Detection of bacterial agents causing prostate infection by culture and molecular methods from biopsy specimens.

Background and Objectives: Prostatitis affects about 16% of men in their lifetime and sometimes leading to prostate cancer. Bacterial infections are the most common causes of prostatitis. Diagnosis of the causative agents of bacterial prostate infections plays an essential role in timely treating and preventing secondary complications. This study isolated bacterial infectious agents in patients' surgical prostate and evaluated them by routine and molecular microbiological methods. Materials and Methods: In this cross-sectional study, 72 prostate biopsy specimens were collected from the Orology Departmen of hospitals of Qazvin University of Medical Sciences. All samples were cultured in aerobic and anaerobic conditions. Antibiotic susceptibility test by Kirby-Bauer standard method was performed for all isolated bacteria. In addition, all isolated bacteria were identified using 16S rDNA PCR and sanger sequencing methods. Also, TaqMan real-time PCR was applied to detect Ureaplasm aurealyticum, Mycoplasma hominins, and Mycoplasma genitalium. Results: In conventional culture method, out of 18 positive samples, 15 samples (83.3%) were Gram-negative bacteria and 3 samples (16.6%) were Gram-positive bacteria, containing Escherichia coli (55.5%), Klebsiella pneumoniae (11.1%), Enterobacter cloacae (5.5%), Pseudomonas aeruginosa (11.1%), Staphylococcus aureus (11.1%), and Enterococcus faecalis (5.5%). The results of molecular identification methods were the same as conventional culture results. Also, four patients were Ureaplasm aurealyticum, and three patients were positive for Mycoplasma hominis. Conclusion: Most bacteria isolated from prostate specimens belonged to the Enterobacteriaceae family, especially Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae. Staphylococcus aureus and Enterococcus faecalis were cocci isolated in the specimens too. Also, Ureaplasma urealyticum, and Mycoplasma hominis were identified in prostatitis.

Detection of Extended-Spectrum ß-Lactamases among Acinetobacter Baumannii Isolated from Hospitals of Qazvin, Iran.

BACKGROUND: Acinetobacter baumannii is a major contributor to nosocomial infections. Extended-spectrum ß-lactamase (ESBL)-producing A. baumannii is spreading worldwide. We aimed to determine the frequency of ESBL-encoding genes in clinical isolates of A. baumannii and to access their clonal relationship by repetitive extragenic palindromic-PCR (rep-PCR). METHODS: In this descriptive cross-sectional study, 203 isolates of A. baumannii were collected from Qazvin hospitals. The Identification of isolates was performed by standard laboratory methods. To verify ESBL production, all isolates were screened by disk agar diffusion and confirmed by the combined disk method. Subsequently, ESBL-encoding genes were detected by PCR and sequencing. Possible clonal association of ESBL-producing isolates was evaluated using rep-PCR. RESULTS: Two hundred (98.5%) isolates showed reduced susceptibility to one of the antibiotics used in the ESBL screening test, of which 127 isolates (62.6%) produced ESBL. PCR results showed blaOXA-1 (20.5%) was the most prevalent gene followed by blaTEM-1 (20%), blaGES-1 (15.7%), blaCTX-M-15 (7.9%), and blaPER-1 (1.6%). Rep-PCR results revealed that ESBL-producing isolates belonged to clones A (85%), B (13.4%), and C (1.6%). CONCLUSION: Our study showed the significant presence of blaOXA-1, blaTEM-1, blaGES-1, blaCTX-M-15, and blaPER-1 genes in ESBL-producing A. baumannii isolates in the studied hospitals. This is the first report on the emergence of blaOXA-1 gene in these isolates in Iran. The use of comprehensive antimicrobial treatment guidelines based on laboratory data and appropriate infection control interventions are essential.

The Effects of Synbiotic Supplementation on Carotid Intima-Media Thickness, Biomarkers of Inflammation, and Oxidative Stress in People with Overweight, Diabetes, and Coronary Heart Disease: a Randomized, Double-Blind, Placebo-Controlled Trial.

Synbiotics are known to exert multiple beneficial effects, including anti-inflammatory and antioxidant actions. The aim of this study was to evaluate the effects of synbiotic supplementation on carotid intima-media thickness (CIMT), biomarkers of inflammation, and oxidative stress in people with overweight, diabetes, and coronary heart disease (CHD). This randomized, double-blind, placebo-controlled trial was conducted and involved 60 people with overweight, diabetes, and CHD, aged 50-85 years old. Participants were randomly allocated into two groups to take either synbiotic supplements containing three probiotic bacteria spices Lactobacillus acidophilus strain T16 (IBRC-M10785), Lactobacillus casei strain T2 (IBRC-M10783), and Bifidobacterium bifidum strain T1 (IBRC-M10771) (2 × 109 CFU/g each) plus 800 mg inulin or placebo (n = 30 each group) for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week intervention period to determine metabolic variables. After the 12-week intervention, compared with the placebo, synbiotic supplementation significantly reduced serum high-sensitivity C-reactive protein (hs-CRP) (- 3101.7 ± 5109.1 vs. - 6.2 ± 3163.6 ng/mL, P = 0.02), plasma malondialdehyde (MDA) (- 0.6 ± 1.0 vs. - 0.1 ± 0.3 µmol/L, P = 0.01), and significantly increased nitric oxide (NO) levels (+ 7.8 ± 10.3 vs. - 3.6 ± 6.9 µmol/L, P < 0.001). We did not observe any significant changes of synbiotic supplementation on other biomarkers of oxidative stress and CIMT levels. Overall, synbiotic supplementation for 12 weeks among people with overweight, diabetes, and CHD had beneficial effects on serum hs-CRP, plasma NO, and MDA levels; however, it did not have any effect on other biomarkers of oxidative stress and CIMT levels.

Curcumin nanomicelle improves semen parameters, oxidative stress, inflammatory biomarkers, and reproductive hormones in infertile men: A randomized clinical trial.

At least 50% of infertile couple's problems are related to male factor infertility. This Randomized, Double-Blind, Placebo-Controlled Clinical Trial conducted in Urology unit of Infertility Clinic on 60 infertile men. Patients were randomly assigned to one of intervention and placebo (n = 30) groups. Finally, 28 subjects in each group completed the study. Participants in the intervention group took daily 80 mg curcumin nanomicelle and those in the placebo group took daily placebo for 10 weeks. Semen analysis, anthropometric, physical activity assessments, total antioxidant capacity, malondialdehyde, inflammatory factors, and reproductive hormones were measured at the baseline and at the end of the study. At the end of study, statistically significant differences were seen in the total sperm count, sperm concentration, and motility in the intervention group to the control group. In treatment group, the total sperm count, sperm concentration, and motility levels were also statistically increased at the end of study compared to the baseline values. Curcumin nanomicelle supplementation also resulted in a statistically significant improvement in plasma levels of total antioxidant capacity, malondialdehyde, C-reactive protein, and tumor necrosis factor a in comparison to the placebo. Medical therapy of asthenoteratospermia with curcumin nanomicelle supplement could improve quality of semen parameters. However, further investigation is suggested in this regard.

Urinary infection before and after prostatectomy.

To determine the prevalence of pre and post prostatectomy related urinary tract infection and its correlation with peri-operative events, we studied 120 patients who underwent prostatectomy due to benign prostatic hypertrophy from September 2005 to September 2006. Urine cultures were performed before the operations, after a week, and three months later. Data including prostate volume, prostatic specific antigen (PSA), post voiding residue (PVR) and histopathological reports as well as the duration of urinary leak, bladder irrigation, hospitalization, and catheterization were studied. The mean age of the studied patients was 70.5 +/- 8 years. Significant preoperative bacteriuria was revealed in 18 (15%) patients of whom 14(77%) patients developed negative cultures following the operation. Postoperative bacteriuria was detected in 9(7.5%) patients who negative urine cultures preoperatively. Pre and post operative micro-organisms were different in the majority of the cases. The mean PSA was higher in patients with a positive history of infection. Following prostatectomy, patients with positive urine cultures had significantly longer urinary leakage, catheterization, and hospital stays compared with those who remained culture negative. We conclude that the incidence of positive urine culture pri-prostatectomy for BPH can be improved by appropriate antibiotic therapy, and the risk factors for postoperative urinary infection include preoperative infection, prolonged urinary leakage, catheterization, and hospital stay. The elevated PSA may be a risk factor.

Premature ejaculation and serum leptin level: a diagnostic case-control study.

INTRODUCTION: Premature ejaculation (PE) is regarded as the most common male sexual disorder. To date, there is no accurate and objective diagnostic test for PE. AIM: To determine the diagnostic value of serum leptin level for PE. METHODS: In a case-control design, the serum leptin level of 46 PE patients referred to our outpatient clinic were determined and compared with 44 control patients referred to the same clinic with the complaint of nephrolithiasis. PE was defined based on the Diagnostic and Statistical Manual of Mental Disorders IV criteria and an intravaginal ejaculatory latency time of less than a minute. MAIN OUTCOME MEASURES: Serum leptin level and presence of PE. RESULTS: The PE patients had significantly higher serum leptin levels (8.3+/-3 ng/mL) than the controls (3.3+/-1 ng/mL) (P<0.001). Sensitivity and specificity for the test as a predictive diagnostic tool for PE were 80.4% and 97.7%, respectively, at the cutoff value of 6.3 ng/mL. CONCLUSIONS: According to our results, leptin level in patients with PE was significantly higher than in the control subjects. More studies are necessary to determine the value of serum leptin as a diagnostic tool for PE.
