Slow Acceptance of Universal Antiretroviral Therapy (ART) Among Mothers Enrolled in IMPAACT PROMISE Studies Across the Globe.

The PROMISE trial enrolled asymptomatic HIV-infected pregnant and postpartum women not eligible for antiretroviral treatment (ART) per local guidelines and randomly assigned proven antiretroviral strategies to assess relative efficacy for perinatal prevention plus maternal/infant safety and maternal health. The START study subsequently demonstrated clear benefit in initiating ART regardless of CD4 count. Active PROMISE participants were informed of results and women not receiving ART were strongly recommended to immediately initiate treatment to optimize their own health. We recorded their decision and the primary reason given for accepting or rejecting the universal ART offer after receiving the START information. One-third of participants did not initiate ART after the initial session, wanting more time to consider. Six sessions were required to attain 95% uptake. The slow uptake of universal ART highlights the need to prepare individuals and sensitize communities regarding the personal and population benefits of the "Treat All" strategy.

Role of endothelin receptors and relationship with nitric oxide synthase in impaired erectile response in diabetic rats.

To evaluate the protective role of bosentan (BOS), an endothelin-1 (ET-1) receptor antagonist, and to show the changes in rats with experimentally induced diabetic erectile dysfunction (ED), a total of 24 albino Wistar rats were allocated into four groups. Group 1 was the healthy group and Group 2 had diabetes mellitus (DM) induced by intraperitoneal injection of 60 mg kg-1 streptozotocin (STZ). Following the establishment of DM, Group 3 and Group 4 were treated with oral BOS doses of 50 mg kg-1 and 100 mg kg-1 , respectively, for 60 days. At the end of the treatment, we evaluated yawning and erection response to apomorphine treatment and then the animals were sacrificed. ET-1, eNOS, iNOS, tumour necrosis factor (TNF)-α, ET-RA and ET-RB mRNA expressions were analysed in cavernosal tissue. It was observed that yawning and erection response decreased in the diabetic group; however, both of these improved with BOS treatment. While ET-1, TNF-α and iNOS gene expressions increased, eNOS, ET-RA and ET-RB gene expressions decreased in the DM group compared to the healthy group. DM has a negative impact on cavernosal tissue blood flow through activating vasoconstrictor mediators in cavernosal tissue. BOS regulates significantly eNOS, iNOS and TNF-α expressions in a dose-dependent manner.

Serum homocysteine levels and sildenafil 50 mg response in young-adult male patients without vascular risk factors.

The aim of the present study was to investigate serum homocysteine levels in patients with erectile dysfunction and to evaluate the relationship between serum homocysteine levels and response to the standard 50 mg phosphodiesterase 5 inhibitor treatment. Twenty-eight erectile dysfunction patients having normal vascular parameter according to Penile Doppler Ultrasonography and twenty healthy subjects were enrolled in the study. All subjects filled The International Index of Erectile Function (IIEF) questionnaire. A total of 4-6 doses of phosphodiesterase 5 inhibitor (sildenafil 50 mg) were given to patients. Later, they were divided into two groups as sildenafil responder and non-responder. Serum homocysteine levels were compared in groups based on sildenafil response. Compared with healthy subject, higher homocysteine levels were observed in patients with erectile dysfunction (p = 0.005), especially in sildenafil non-responder group (p = 0.005). There was significant negative correlation between homocysteine and IIEF scores in group responder to sildenafil treatment (r = -0.698, p = 0.008). Mean IIEF scores of patients with non-responder to sildenafil 50 mg were lower than those of controls (p = 0.0001), but mean IIEF scores of patients with responders approached values observed in control subjects (p = 0.002). The results indicated that measurement of serum homocysteine levels could be used as a marker for the evaluation of efficacy of phosphodiesterase 5 inhibitor and the selection of efficacious alternative therapies.

Relationship between serum vitamin D levels semen parameters and sperm DNA damage in men with unexplained infertility.

OBJECTIVE: The aim of the study was to investigate the relationship between serum level of vitamin D, semen analysis parameters and sperm DNA damage in men with unexplained subfertility. PATIENTS AND METHODS: Fifty-eight men diagnosed with unexplained infertility and 50 age and BMI matched fertile men were included in the study. A participant whose semen parameter is normal but pregnancy is not achieved was accepted as unexplained male infertility. Blood samples were taken from all participants following three-day abstinence for measurement of vitamin D. Sperm DNA damage was assessed by Aniline Blue staining of the collected samples. RESULTS: Compared with the fertile men, male patients with unexplained infertility had significantly lower vit D levels (27.00 ng/mL (12.63-39.30) vs. 23.66 ng/mL (7.50-55.00), p<0.004). While the number of patients with vitamin D levels lower than 20 ng/mL was 26 (44.8%) in the infertile group, it was recorded as 5 (10.0%) in the fertile group (p<0.001). DNA damage was found in 31.50% (9.0-71.0) of the infertile men and 26.00% (11.0-54.0) of the fertile men. DNA damage was found to be significantly higher in the unexplained infertile group (p<0.002). In men with unexplained male infertility, serum vit D levels were positively correlated with total sperm count (r = 0.527, p<0.001), total motility (r = 0.527, p<0.001) and sperm morphology (r = 0.416, p = 0.001). There was a negative and significant correlation between vit D levels and sperm DNA damage (r = -0.605, p<0.001). In the logistic regression analysis, serum vit D > 20 ng/mL led to an improvement in fertility outcome. CONCLUSIONS: Men with unexplained infertility exhibit decreased serum vit D levels and increased sperm DNA damage.

The difference of heart rate recovery between males with and without erectile dysfunction.

AIM: In this study, we aimed to investigate the relationship between heart rate recovery (HRR) time and Chronotropic Index (CHIND) parameters, which also reflect autonomic function, after exercise stress test (EST) in males with or without erectile dysfunction (ED), and we investigated the relationship between HRR and CHIND and serum steroid hormone levels. MATERIAL AND METHODS: A total of 135 participants (mean age: 45.0 +/- 11.8 years) were enrolled into the study. Detailed biochemical and hormonal analyses, 12-lead electrocardiography and EST (Treadmill) were performed in all participants. Erectile function was assessed using the International Index of Erectile Function (IIEF) questionnaire form. Patients were categorized into two groups according to their IIEF scores as ED (+) (IIEF < 26) and ED (-) (IIEF > or = 26). Afterward, statistical analyses were performed to evaluate the correlations between ED and HRR and CHIND. RESULTS: A total of 65 patients were ED (+) (mean age 44.9 +/- 6.4 years), while 70 patients (mean age 43.7 +/- 7.7 years) had normal erectile status. There were statistically significant differences in CHIND (P = 0.015) and HRR time (P = 0.037) between ED (+) and ED (-) patients. In correlation analysis, IIEF score was found positively correlated with HRR and metabolic equivalent (MET) values (r(HRR)= 0.293, P = 0.037; r(METs)= 0.388, P = 0.011, respectively). Linear regression analysis revealed that METs value and total exercise time had a more linear relationship with IIEF score compared to the other EST parameters (p(METs)= 0.002 and p(TET)= 0.015, respectively). CONCLUSION: Chronotropic incompetence and dynamic postexercise autonomic dysfunction are present in ED patients. This condition may reflect decreased functional capacity and exercise intolerance in these patients.

The relationship between serum sex steroid levels and heart rate variability parameters in males and the effect of age.

OBJECTIVES: We evaluated the relationships between sex steroid levels and heart rate variability (HRV) parameters. STUDY DESIGN: The study included 114 male subjects (mean age 46.6±11.3 years) presenting to our department for cardiologic evaluation. Hormonal analysis included serum levels of luteinizing hormone, prolactin, total testosterone (TT), free testosterone, estradiol (E2), and dehydroepiandrosterone sulfate (DHEA-S). Parameters of HRV were derived from 24-hour Holter monitoring. The associations between serum sex steroid levels and HRV parameters were investigated in three age groups (20-39 years; 40-59 years; >60 years). RESULTS: All the participants had normal biochemical results. The three age groups were similar in terms of anthropometric measurements. Among sex steroids analyzed, only serum DHEA-S level was significantly different among the groups (p=0.026), showing a decreasing trend with age. In the evaluation of HRV, all parasympathetic activities decreased (for HFn, pNN50, and rMSDD: p=0.001, p=0.000, and p=0.000, respectively), while only LF/HF among sympathetic activities increased (p=0.000) with age. Partial correlation analysis with control of age and waist circumference showed that TT and DHEA-S were positively correlated with HFn (parasympathetic parameter), and were in negative correlation with LF/HF24 hours and global sympathetic index (GSI) (sympathetic parameters). Serum E2 level was negatively correlated with the parasympathetic parameter of rMSSD, and positively correlated with LF/HF24 hours and GSI. Among serum sex steroids, DHEA-S was the most correlated parameter with autonomic functions. CONCLUSION: Our results showed positive correlations between androgens and parasympathetic activity and between estradiol and sympathetic activity in men, independent from anthropometric factors.

The effect of Behçet's disease on sexual function and psychiatric status of premenopausal women.

INTRODUCTION: Little is known about the relationship between Behçet's disease (BD) and female sexual dysfunction (FSD). AIMS: The aims were to evaluate the prevalence of FSD in premenopausal BD patients and to compare hormonal and psychiatric conditions to healthy subjects. METHODS: A total of 71 married women with BD and 63 healthy married women between 18 and 44 years old were enrolled into the study. After evaluating detailed history and physical examination, serum steroid hormone levels were measured. Presence of genital ulcerations in physical examination and any medical treatment were recorded in patients. All subjects were asked to complete the Female Sexual Function Index (FSFI) for sexual status and Beck Depression Inventory (BDI) for psychiatric assessment. MAIN OUTCOMES MEASURES: FSFI and BDI scores and serum sex steroid hormone levels were measured in women with BD and healthy controls. RESULTS: The mean BDI score of patients was significantly greater than that for controls (P = 0.001), and there was a statistically significant difference between BDI scores (Pearson chi2 = 19.109, P = 0.001). FSD was found in 34 patients with BD (47.9%) and in 11 controls (17.5%). A statistically significant difference was found between the two groups (Pearson chi2 = 13.855, P = 0.001). While the most common sexual problem in the patients with BD was diminished arousal (n = 49, 69.0%), diminished desire was found in 32 patients (45.1%) and lubrication problems in 36 patients (50.7%). There was a statistically significant negative correlation between BDI and FSFI score in BD patients. On the contrary, there was no relationship between FSFI and presence of genital ulcerations. CONCLUSION: FSD is more common in BD patients than in healthy subjects. We conclude that depressive mood according to the BDI scale correlates with the sexual status of BD patients, and this may be because of the depressive effect of BD as a chronic disease.

Hereditary haemochromatosis gene (HFE) H63D mutation shows an association with abnormal sperm motility.

The aim of this study was to screen infertile men for HFE H63D mutation in correlation with clinical characteristics of infertile men (sperm concentration, sperm motility, morphology, testicular volume, Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH) and total Testosterone levels) and find out if the HFE H63D mutation has an effect on male infertility. After excluding hormonal treatment, any scrotal pathology, having any systemic diseases such as diabetes mellitus, sickle cell anemia and microdeletions of the Y chromosome, a total of 148 infertile men with age range between 17 and 52-years-old (average age 29.6 +/- 7.2) were enrolled into the study. Our analysis indicates that the mean FSH levels are significantly higher (6.3 +/- 4.6 mIU/ml, P = 0.03), whereas sperm motility is significantly lower (36.6 +/- 28.1%, P = 0.01) in the infertile men with the HFE H63D mutation compared with subjects lacking this mutation. Comparison of allele frequencies of the infertile men with Ts < 50% versus the infertile men with Ts > 50% revealed a significant difference as expected (P = 0.001, OR = 0.14, %95 CI = 0.04-0.44). Comparison of allele frequencies of infertile men with abnormal sperm motility versus infertile men with normal sperm motility revealed a highly significant difference (P = 0.005, OR = 3.11, %95 CI = 1.41-6.86). Thus, the HFE H63D mutation seems to be an important risk factor for impaired sperm motility and is clinically associated with male infertility.

Significance of p57(Kip2) down-regulation in oncogenesis of bladder carcinoma: an immunohistochemical study.

AIMS AND BACKGROUND: Cyclin-dependent kinase inhibitors have important roles in the oncogenesis of various tumors including urothelial cancer. The aim of this study was to establish the importance of p57(Kip2), a unique cyclin-dependent kinase inhibitor, in the oncogenesis of bladder carcinoma. This article also focused on another cyclin-dependent kinase inhibitor, p27(Kip1), and telomerase enzyme and examined the relationship between these proteins. MATERIAL AND METHODS: Thirty-one patients with urothelial carcinomas of the bladder and 7 cases with normal urinary bladder mucosa were included in the study. Immunohistochemical study was performed by monoclonal antibodies of p27(Kip1), p57(Kip2), and the telomerase subunit (hTERT). All immunohistochemical preparations were evaluated by an immunohistochemical histological score. RESULTS: p57(Kip2) and p27Kip1) expression were seen in all of the cases of normal mucosa. In carcinoma cases, 8 of 31 (25.8%) showed p57(Kip2) nuclear positivity and 20 of 31 (64.5%) expressed nuclear p27(Kip1). HSCOREs of carcinoma cases showed lower scores of nuclear p57(Kip2) and p27(Kip1) than normal mucosa, but only HSCOREs of nuclear p57(Kip2) (P = 0.001) showed statistical significance. Despite unknown significance, cytoplasmic p57(Kip2) and p27(Kip1) were also evaluated. Immunohistochemical analysis showed that carcinomas expressed higher HSCOREs of hTERT than normal mucosa, and there was a significant difference (P = 0.026) between muscle invasive carcinomas and normal mucosa. CONCLUSIONS: The data showed that p57(Kip2) down-regulation along with p27(Kip1) is a well-established feature of urothelial carcinoma. Probably, this down-regulation of cyclin-dependent kinase inhibitors supports the proliferation phase of oncogenesis. In the study, we also showed that hTERT expression was up-regulated in higher stages of urothelial carcinoma.

Effects of vardenafil on intraocular pressure and orbital hemodynamics.

PURPOSE: The aim of this study was to investigate the effects of vardenafil on systemic blood pressure, intraocular pressure (IOP), and orbital hemodynamics. METHODS: Twenty-one (21) volunteers suffering erectile dysfunction, with an average age of 51.5 +/- 6.2 years, were enrolled into the study. Brachial blood pressures and IOP were measured, the peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) of the ophthalmic, central retinal, and posterior ciliary arteries were evaluated by color Doppler ultrasonography (CDU) before vardenafil intake. All measurements were repeated after 20 min of vardenafil intake. A paired Student t test was used to evaluate the changes. RESULTS: Systolic blood pressure did not change significantly where diastolic blood pressure decreased significantly (P = 0.043) after drug ingestion. There was no significant change in IOP. Increase in EDV of CRA was significant (P = 0.04), but the increase of orbital blood flow velocities of OA and PCA were insignificant. CONCLUSIONS: The recommended dose of vardenafil has no negative effects on orbital hemodynamics and IOP in patients with erectile dysfunction.

Is there a relationship among age, international index of erectile function, international prostate symptom score, and aging males' symptoms score?

PURPOSE: To investigate the relationship among the International Index of Erectile Function (IIEF), International Prostate Symptom Score (IPSS), and Aging Males' Symptoms (AMS) scale scores in various age groups of males. PATIENTS AND METHODS: A total of 307 male patients enrolled in the study. Mean age was 52.3 (range 21-77) years. Group 1 consisted of 51 (< or =39 years), Group 2 consisted of 160 (40-59 years), and Group 3 consisted of 96 (> or =60 years) patients. First five and 15th questions of the IIEF, IPSS, and AMS scale were replied by all the patients. The patients were assessed based on the IIEF for erectile dysfunction (ED), IPSS for lower urinary tract symptoms (LUTS), and AMS scale for Symptomatic Late-Onset Hypogonadism (SLOH). RESULTS: ED, LUTS, and SLOH symptoms were detected in 236 (76.8%), 162 (52.8%), and 184 (59.9%) patients. Except for total AMS scores, IIEF and IPSS scores were significantly different among the groups (p (AMS) = 0.320, p (IIEF) = 0.000, p (IPSS) = 0.000). In the comparisons of the IIEF scores between the each group, significant differences were observed (p (Group1-Group2) = 0.000, p (Group1-Group3) = 0.000, p (Group2-Group3) = 0.000). Nevertheless, IPSS score was significantly lower in the patients with age < or =39 years than the other age groups (p = 0.000). CONCLUSIONS: In the present study, ED ratio and LUTS severity significantly increased in older men. We did not find significant relationship between aging and SLOH symptoms. In the light of our results, LUTS seems to be an important risk factor on erectile function.

Current concepts in the diagnosis and management of metabolic complications of HIV infection and its therapy.

Changes in fat distribution, dyslipidemia, disordered glucose metabolism, and lactic acidosis have emerged as significant challenges to the treatment of human immunodeficiency virus (HIV) infection. Over the past decade, numerous investigations have been conducted to better define these conditions, identify risk factors associated with their development, and test potential therapeutic interventions. The lack of standardized diagnostic criteria, as well as disparate study populations and research methods, have led to conflicting data regarding the diagnosis and treatment of metabolic and body shape disorders associated with HIV infection. On the basis of a review of the medical literature published and/or data presented before April 2006, we have prepared a guide to assist the clinician in the detection and management of these complications.

Endogenous sex steroids and bone mineral density in healthy men.

OBJECTIVE: To evaluate the role of endogenous sex steroids on bone mineral density (BMD) in healthy Turkish men. METHODS: Serum total testosterone (TT), free testosterone (FT), dehydroepiandrosterone sulfate and estradiol levels were assayed in 174 healthy men of 240 volunteers, aged 22-76 years. Dual-energy X-ray absorptiometry was used to measure the BMD (g/cm(2)) of lumbar spine, femoral neck and non-dominant proximal and distal radius-ulna sites. Linear regressions were conducted using each BMD site as the dependent variable and each sex steroid as the independent variable. Four models were run for each bone site and sex steroid; crude, age-adjusted, adjusted for age and body mass index (BMI), and adjusted for age, BMI and cigarette-smoking. RESULTS: The mean age and BMI of men enrolled in the study were 47.7 +/- 13.7 years and 26.9 +/- 3.6 kg/m(2). Log of FT was significantly associated with the BMD of distal forearm in all models analyzing the crude and adjusted effects. Dehydroepiandrosterone sulfate effect on BMD of proximal forearm came closer to the level of statistical significance when adjusted with age, BMI and cigarette-smoking. Estradiol and TT levels were not found to be associated with BMD of any sites measured. CONCLUSION: Among the endogenous sex steroids in men, predominantly FT seems to be one of the determinants of BMD. Therefore a decrease in serum levels of testosterone in aging male or secondary causes may negatively affect BMD.

Common symptoms in men with prostatic inflammation.

PURPOSE: We evaluated 96 patients with prostatic inflammation in terms of their symptoms and aimed to find common types and frequencies of symptoms in these patients. PATIENTS AND METHODS: The mean age of the patients was 38.0+/-8.7 (range 21-58) years. Physical examination, digital rectal examination, microscopic prostatic secretion assessment and urine cultures after taking a detailed medical history were performed. Urine samples before and after prostatic massage were collected for urine culture. Frequency and types of patients' symptoms were evaluated. All patients were asked about lower urinary tract symptoms, sexual dysfunction and other complaints. RESULTS: Lower urinary tract symptoms and lumbal pain were more prevalent in elder patients. Ejaculation disorder was the most common sexual problem (n=65, 67.7%). Erectile dysfunction and decreased libido were observed in 29 (30.2%) and 22 (22.9%) of the patients. Other complaints were lumbal pain (n=34, 35.4%), perineal fullness (n=50, 52.1%), haemospermia (n=20, 20.8%) and scrotal pain (n=43, 44.8%). CONCLUSION: Prostatic inflammation was usually seen in men of the third and fourth decade. Sexual dysfunction was the most common symptom in this particular group of patients.

Magnetic resonance imaging (MRI) in penile metastases of extragenitourinary cancers.

BACKGROUND: The aim of present study is to evaluate the efficacy of magnetic resonance imaging (MRI) in different types of penile metastases. MATERIALS AND METHODS: In this report, we present three cases of penile metastases that have been developed secondary to extragenitourinary malignancies. Two of them did not have any primary malignancy history. RESULTS: Penile biopsies were performed in all patients and metastatic penile tumours were found due to extragenitourinary malignancies. Penile MRI was performed before biopsies. The findings of MRI were correlated with histopathologic diagnosis. Moreover, penile MRI was found to be more sensitive in the evaluation of the lesions than ultrasonography. CONCLUSION: MRI can be accepted as a reliable non-invasive method for the evaluation of the extent of penile metastases and involvement of tunica albuginea or urethral.

Prognostic importance of RASSF2 expression in patients with gastric cancer who had undergone radical gastrectomy.

BACKGROUND: Although Ras-association domain family of gene 2 (RASSF2) has been shown to undergo promoter methylation at high frequency in some cancer types and in brain metastases, its clinical utility as a useful prognostic molecular marker remains unclear in gastric cancer. METHODS: Prognostic significance of RASSF2 expression was retrospectively analysed by immunohistochemically in 105 patients with gastric cancer who underwent curative gastrectomy. RESULTS: Low RASSF2 expression was detected in 58 (55 %) patients, whereas 47 patients (45 %) had high RASSF2 expression. Lymph node involvement, pT stage, TNM stage, vascular invasion, perineural invasion and the presence of recurrence were found to be significantly related to RASSF2 expression levels. Low PRL-3 expression was closely correlated with lymph node metastasis (p = 0.001), advanced pT stage (p = 0.021), advanced TNM stage (p < 0.001), the presence of vascular invasion (p < 0.001), perineural invasion (p = 0.018) and high prevalence of recurrence (p = 0.003) compared with high RASSF2 expression. The median disease-free survival (DFS) time for patients with low RASSF2 expression was significantly worse than that of patients with high RASSF2 expression (10.2 vs. 50.6 months, p < 0.001). In addition, patients with high RASSF2 expression had the higher overall survival (OS) interval compared to patients with low RASSF2 expression (NR vs. 14.9 months, p < 0.001). In the multivariate analysis, the rate of RASSF2 expression levels was an independent prognostic factor, for DFS [p < 0.001, HR 0.12 (0.10-0.88)] and OS [p < 0.001, HR 0.10 (0.04-0.46)], as were pT stage and TNM stage, respectively. CONCLUSIONS: RASSF2 may be an important molecular marker for carcinogenesis, prognosis and progression in gastric cancer, but the potential value of RASSF2 expression as a useful molecular marker in gastric cancer progression should be evaluated, comprehensively. It would be possible to develop treatments targeting RASSF2 and advance new treatment strategies for gastric cancer.

Effectiveness of eutectic mixture of local anesthetic cream and occlusive dressing with low dosage of fentanyl for pain control during shockwave lithotripsy.

BACKGROUND AND PURPOSE: To investigate the effect and usefulness of Eutectic Mixture of Local Anesthetic (EMLA) applied with an occlusive dressing and used simultaneously with a low dose of fentanyl during shockwave lithotripsy (SWL). PATIENTS AND METHODS: One hundred sixty patients with kidney stones, aged between 19 and 68 years, were randomly divided into seven groups that were treated as follows: group 1: fentanyl 1 microg/kg by intravenous infusion (IV); group 2: IV fentanyl 0.25 microg/kg; group 3: occlusive dressing and IV fentanyl 0.25 microg/kg; group 4: placebo cream and IV fentanyl 0.25 microg/kg; group 5: EMLA cream and IV fentanyl 0.25 microg/kg; group 6: placebo cream and IV fentanyl 0.25 microg/kg with an occlusive dressing; and group 7: EMLA cream and IV fentanyl 0.25 microg/kg with an occlusive dressing. The mean arterial pressure (MAP), heart rate, ventilatory rate, and oxygen saturation (SpO(2)) were recorded on all patients. A visual analog scale 0-100 mm (VAS) was used for the evaluation of pain. The skin integrity was inspected to detect any lesions after SWL. RESULTS: The SpO(2) in group 1 was lower statistically than in the other groups. The VAS score in group 7 was clearly lower than in the others in the first, tenth, and twentieth minutes and at the end of SWL. In groups 6 and 7, additional fentanyl doses were lower than in the other groups, but only in group 7 was the total fentanyl dosage low. Skin lesions were not seen only in groups 3, 6, and 7. CONCLUSION: Use of EMLA and an occlusive dressing with low doses of fentanyl during SWL provides appropriate analgesia with minimal morbidity.

BAG-1 expression in hyperplastic and neoplastic prostate tissue: is there any relationship with BCL-related proteins and androgen receptor status?

AIMS AND BACKGROUND: To evaluate the function and distribution of BAG-1 protein in hyperplastic and neoplastic prostate tissue and establish the relationship between this protein and BCL-related proteins (BCL-2 and BAX), androgen receptor (AR) expression and chromogranin A. METHODS: Twenty-eight prostatic adenocarcinomas and 16 prostate hyperplasias were included in this retrospective study. BAG-1, BCL-2, BAX, androgen receptor and chromogranin A immunostaining was performed by means of standard avidin-biotin peroxidase methods. The M30 antibody was used to identify preapoptotic and apoptotic cells. The immunohistochemical histological score (HSCORE) semiquantative system was used to evaluate immunohistochemical staining. RESULTS: Statistical analysis showed a significant difference in HSCOREs of BAX, M30 and AR between the carcinoma and hyperplasia groups. Carcinomas expressed higher HSCOREs of these markers than hyperplasias. There were significant differences in nuclear and cytoplasmic BAG-1 positivity between high and low-grade carcinomas. BAG-1 expression was higher in low-grade carcinomas. In the carcinoma group there was a positive correlation (Pearson) between BCL-2 and cytoplasmic/nuclear BAG-1. In the hyperplasia group there was a negative correlation between BAX and BCL-2, and between AR and M30. We also detected a positive correlation between AR and nuclear/cytoplasmic BAG-1 and between nuclear and cytoplasmic BAG-1 in hyperplasias. BAG-1 showed the same specific basal cell localization as BCL-2 in hyperplastic and normal glands. CONCLUSIONS: The BAG-1 protein showed a distinct distribution pattern in hyperplastic and neoplastic prostate. BAG-1 in association with BCL-2 inhibits apoptosis and may prolong the life of neoplastic cells and give them a chance to gain new oncogenic features in early carcinogenesis.

Terazosin in the treatment of premature ejaculation: a short-term follow-up.

AIM: The aim of the present study was to evaluate the efficacy of terazosine in patients with premature ejaculation and lower urinary tract symptoms (LUTS), after excluding other sexual disorders and chronic prostatitis. METHODS: A total of 90 patients with premature ejaculation and LUTS were enrolled to the study after excluding sexual disorders, prostatitis and benign prostatic hyperplasia. The patients were divided into two groups. Sixty patients in group 1 were treated with terazosine 5 mg daily for a month. Patients were followed monthly and questioned for their ejaculation problem. The results were classified as cure, improvement and ineffective. If patients showed improvement and ineffectiveness, the treatment was continued with 10 mg daily for the following month. Group 2 was included 30 patients, and placebo was applied for a month. At the end of this period, in patients who did not show any improvement, terazosine 10 mg was started. RESULTS: In the treatment group, at the 1st month follow-up, 21 patients (35%) were cured, 20 (33.3%) showed improvement. In 19 (31.7%) patients, the treatment was ineffective. In group 2, 9 (30%) patients showed improvement and the rest had no-changes after one-month follow up. There was statistically significant difference between two groups (Pearson chi2 test = 0.000). Later, terazosine 10 mg was given to the patients in group 2 and to the patients who showed improvement or unsuccessful result with terazosine 5 mg. With terazosine 10 mg, 10 (14.5%) patients were cured, 29 (42.2%) patients were improved. Finally, terazosine treatment in patients with premature ejaculation was found to be effective in 60 patients (66.7%). CONCLUSION: Alpha blockers seem to be physiological medical agents in the treatment of premature ejaculation since ejaculation is under sympathetic control. Moreover, these agents are effective in lower urinary tract and they should be used in patients with premature ejaculation and lower urinary tract symptoms.

Chinese herbal medicine for miscarriage affects decidual micro-environment and fetal growth.

INTRODUCTION: Intrauterine growth restriction complicates 5-10% of pregnancies. This study aims to test the hypothesis that Chinese herbal formula, JLFC01, affects pregnancy and fetal development by modulating the pro-inflammatory decidual micro-environment. METHODS: Human decidua from gestational age-matched elective terminations or incomplete/missed abortion was immunostained using anti-CD68 + anti-CD86 or anti-CD163 antibodies. qRT-PCR and Luminex assay measured the effects of JLFC01 on IL-1ß- or TNF-α-induced cytokine expression in first trimester decidual cells and on an established spontaneous abortion/intrauterine growth restriction (SA/IUGR)-prone mouse placentae. The effect of JLFC01 on human endometrial endothelial cell angiogenesis was evaluated by average area, length and numbers of branching points of tube formation. Food intake, litter size, fetal weight, placental weight and resorption rate were recorded in SA/IUGR-prone mouse treated with JLFC01. qRT-PCR, Western blot and immunohistochemistry assessed the expression of mouse placental IGF-I and IGF-IR. RESULTS: In spontaneous abortion, numbers of decidual macrophages expressing CD86 and CD163 are increased and decreased, respectively. JLFC01 reduces IL-1ß- or TNF-α-induced GM-CSF, M-CSF, C-C motif ligand 2 (CCL2), interferon-γ-inducible protein-10 (IP-10), CCL5 and IL-8 production in first trimester decidual cells. JLFC01 suppresses the activity of IL-1ß- or TNF-α-treated first trimester decidual cells in enhancing macrophage-inhibited angiogenesis. In SA/IUGR-prone mice, JLFC01 increases maternal food intake, litter size, fetal and placental weight, and reduces fetal resorption rate. JLFC01 induces IGF-I and IGF-IR expression and inhibits M-CSF, CCL2, CCL5, CCL11, CCL3 and G-CSF expression in the placentae. DISCUSSION: JLFC01 improves gestation by inhibiting decidual inflammation, enhancing angiogenesis and promoting fetal growth.
