Obesity is not a descriptive factor for oxidative stress and viscosity in follicular fluid of in vitro fertilization patients.

BACKGROUND: Obesity's impact on micro-environmental oxidative stress and follicular fluid (FF) viscosity and whether or not it has any effect on in vitro fertilization (IVF) success is a matter of debate. AIMS: In this study, our aim was to evaluate the levels of oxidative stress markers and the FF viscosity in obese and non-obese patients. METHODS: Eighty norm-responder patients undergoing IVF were prospectively grouped according to their body mass indexes (BMI). Group 1 (n = 40) and group 2 (n = 40) had BMI values of ≤24.9 and ≥25.0, respectively. Total sulfhydryl (RSH) levels (nmol/m) and the formation of thiobarbituric acid-reactive substances (malondialdehyde, or MDA) (µmol/ml) in FFs were quantified. For the first time in our study, FF viscosity with changing BMI values was also determined. RESULTS: The mean levels of MDA (µmol/ml) and RSH (nmol/ml) were not significantly different between groups (1.37 ± 0.51; 1.51 ± 0.51; p > 0.05 for MDA and 0.42 ± 0.30; 0.41 ± 0.20; p > 0.05 for RSH, respectively). Similarly, the FF viscosity (centipoise) was not different between groups (1.28 ± 0.28; 1.30 ± 0.19; p < 0.05, respectively). Independent of BMI, no correlation was found between FF levels of oxidative markers and the number of oocytes retrieved or the fertilization rates. CONCLUSIONS: In our study, we found no difference in the levels of follicular oxidative and anti-oxidative markers or the follicular fluid viscosity with changing BMI values. We also demonstrated that the levels of oxidative stress markers and the viscosity of follicular fluid did not affect clinical outcomes.

Immediate risk of HSIL presence in women who have both ASC-US cytology and negative high-risk HPV test.

PURPOSE: The authors aimed to detect immediate risk of having high grade squamous lesions (HSIL) in atypical squamous cells of uncertain significance(AS-CUS) and concomitant high-risk human papillomavirus (HrHPV) testing as negative [HrHPV(negative)AS-CUS]. MATERIALS AND METHODS: The authors performed immediate/baseline colposcopy on concomitant HrHPV (negative)AS-CUS cases. Pap tests were evaluated with liquid-based cytology (LBC) and HrHPV detection was performed in LBC material with PCR. Colposcopic diagnoses and biopsy results were compared with Pap test and HrHPV test results. RESULTS: There were 104 patients over a one-year period. In all, 84 cases were included. Colposcopic biopsies revealed low grade squamous intraepithelial lesion (LSIL) in 19 cases (23%) and HSIL in three cases (4%). Intrauterine device use and smoking were significantly correlated with presence of HSIL (p = 0.005 and p = 0.007 respectively). CONCLUSION: Similar data in literature, 4% of ASC-US-HrHPV (negative) cases are expected to have HSIL in follow-up periods less than six months. The present authors believe clinicians should be more open with their patients about limitations of Pap-HPV testing.

Concordance of sexual dysfunction and dissatisfaction by self-report and those by partner's perception in young adult couples.

We evaluated concordance levels of young adult spouses (N=107 couples, total N=214) with regards to sexual satisfaction by using Golombock-Rust Inventory of Sexual Satisfaction (GRISS). Each spouse of the couples filled out both female and male forms of the GRISS. Self- and spouse-reported scores were analyzed in terms of inter-rater correlation and agreement. The prevalence of overall sexual dissatisfaction was 10.3% and 26.2% in wives and husbands, respectively. The correlation coefficient (r) between the self-reported overall sexual satisfaction scores and those assessed by the spouses was 0.25 (P=0.014) and 0.04 (P=0.680) for wives and husbands, respectively. The sensitivity for perception of partner's sexual problems ranged 11% to 47%, and the specificity was around 64% to 100%, except for vaginismus, which had a sensitivity of 83% and a specificity of 25%. The prevalance-adjusted and bias-adjusted kappa (PABAK) value for overall sexual dissatisfaction reported by themselves and that assessed by their spouses was 0.68 and 0.16 for the wives and husbands, respectively. For specific female sexual problems, the PABAK value was the highest in female dissatisfaction (0.81) followed by anorgasmia (0.78), female avoidance (0.44), vaginismus (0.44), infrequency (0.33), non-communication (0.14) and female nonsensuality (0.14). For specific male sexual problems, the PABAK value was the highest in male nonsensuality (1.00), followed by male dissatisfaction (0.78), infrequency (0.46), non-communication (0.42), male avoidance (0.36), impotence (0.27) and premature ejaculation (-0.04). Our findings suggested that in this clinical sample the partner's perception of sexual dysfunction and dissatisfaction did not correlate well with the subject's self-reported sexual problems, and generally male sexual problems were less correctly perceived by the partners than were female sexual problems. This result may provide helpful information for clinicians who take care of patients' sexual problems.

Levels of neopterin and C-reactive protein in pregnant women with fetal growth restriction.

The aim of this study was to evaluate whether pregnant women with fetal growth restriction (FGR) have higher plasma neopterin and C-reactive protein (CRP) concentrations compared with those with uncomplicated pregnancy. A total of 34 pregnant women with FGR and 62 patients with uncomplicated pregnancy were included. Neopterin and CRP levels were measured at the time of diagnosis. The primary outcome of this study was to compare the neopterin and CRP levels in pregnant women with FGR and those with uncomplicated pregnancies. The secondary outcome of our study was to evaluate the correlation between fetal birth weight and maternal neopterin levels. The serum neopterin levels were significantly elevated in pregnant women with FGR (22.71 ± 7.70 vs 19.15 ± 8.32). However, CRP was not elevated in pregnant women with FGR (7.47 ± 7.59 vs 5.29 ± 3.58). These findings support the hypothesis that pregnancy with FGR is associated with a marked increase in macrophage activation and the natural immune system.

The effect of long-term oral tadalafil treatment on corpus cavernosum function in an experimental spinal cord transection rat model.

OBJECTIVES: The aim of this study was to investigate the pharmacological effects of long-term oral tadalafil treatment on the corpus cavernosum function in rats subjected to experimental spinal cord transection (SCT). METHODS: Thirty young adult, male Sprague­Dawley rats were randomly divided into five groups (n» 6, each), as follows: (1) Control,(2) Control surgery (Sham), (3) Tadalafil (Td), (4) Experimental SCT, and (5) SCT + Tadalafil (SCT + Td). SCT rat model: after removal of T8-T9 spinal processes and laminates, a full-thickness scalpel incision was made in the spinal cord. SCT + Td rat model:rats subjected to SCT were given tadalafil (5mg kg(-1), p.o.) for 4 weeks. Next, the penile cavernous tissues obtained by en blocexcision were trimmed free of the surrounding tissue to isolate cavernosal smooth muscle strips, which were then transferred into the isolated organ baths to investigate isometric tension changes in response to various bioactive agents and electrical field stimulation (EFS). RESULTS: The relaxation response to acetylcholine at 0.01 mM concentration was significantly less in the SCT group compared with other groups. EFS-induced relaxation in the basal and precontracted cavernous tissue preparations was greater in the SCT + Td group than in the SCT group. CONCLUSION: This study demonstrated that long-term tadalafil administration preserves relaxation responses probably by affecting through the nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) pathway in SCT-applied rats. This treatment strategy might preserve the erectile process and prevent the SCT-induced permanent damage in the cavernosal tissue.

Changes in the ovarian stromal blood flow in patients treated with laparoscopic salpingostomy for ectopic pregnancy.

This study is aimed to evaluate the impact of laparoscopic salpingostomy on ovarian stromal blood flow indices in patients with ectopic pregnancy, and to compare the ovarian stromal blood flow indices with matched paired healthy women. We included 37 patients who underwent laparoscopic salpingostomy and 37 age- and parity-matched women as controls. The main outcome was the differences in ovarian volume, antral follicle count (AFC), and ovarian stromal blood flow indices between the study group participants after the surgery and the healthy controls. Comparison of the ovarian parameters between the study group after the surgery and the control group revealed no significant differences in terms of ovarian volume (p = 0.783), AFC (p = 0.253), ovarian stromal S/D ratios (p = 0.054), pulsatility index (PI; p = 0.938) and resistance index (RI; p = 0.041). In addition, comparison of the ovarian parameters before and after the surgical treatment revealed no significant differences in the ovarian volume (p = 0.141), AFC (p = 0.084), ovarian stromal S/D ratios (p = 0.187), PI (p = 0.102) and RI (p = 0.108). In conclusion, laparoscopic salpingostomy does not affect ovarian function in terms of ovarian stromal blood flow indices, ovarian volume, and AFC.

Sexual dysfunction assessment and hormonal correlations in patients with polycystic ovary syndrome.

In this controlled study, we aimed to evaluate the sexual dysfunction of patients with polycystic ovary syndrome (PCOS) in comparison to healthy controls. We enrolled 64 sexually active women in our study. The PCOS group consisted of 32 women who met the Rotterdam diagnostic criteria, and the control group was composed of 32 age-matched, healthy females. In addition to the demographic and clinical characteristics of the participants, the hormonal and biochemical parameters were also studied. All patients were invited to fill out the female sexual function index (FSFI) and Beck's Depression Inventory questionnaires. The prevalence of sexual dysfunction in the PCOS group was similar to controls (25% vs 19%; P=0.54). No significant difference was found according to each domain score of FSFI. Significant negative correlations were found between the total FSFI scores of the PCOS group and the total (r=-0.278) and free testosterone (r=-0.493) levels. Although depressive scores of PCOS patients were higher, they did not show greater impaired sexual functions than age-matched controls according to their FSFI scores. Considering the multifactorial state of female sexual dysfunction, further studies are needed to clarify the impact of PCOS upon sexuality.

Ocular pulse amplitude and retrobulbar blood flow change in dipper and non-dipper individuals.

PURPOSE: To evaluate ocular pulse amplitude (OPA), IOP values, and hemodynamic changes in the ophthalmic artery, central retinal artery, and short posterior ciliary artery in dipper and non-dipper patients. METHODS: A total of 59 right eye measurements of healthy subjects with normotensive were included to the study. Ambulatory blood pressure (BP) monitoring measurement (ABPM), Doppler imaging, and OPA measurements were performed in the same day. The patients in which systolic BP decreased during the nocturnal time by 10% of the diurnal BP or more were called dippers. A patient whose nocturnal systolic BP fell by <10% or even rose was defined as non-dipper. Color Doppler imaging was used for blood flow velocity assessment of ophthalmic, central retinal, and posterior ciliary arteries. For each artery, peak systolic and end-diastolic velocities (PSV and EDV, respectively), resistive index (RI), and pulsalite index (PI) were automatically calculated by the machine. Mean IOP and OPA values were calculated after three consecutive measurements. RESULTS: The mean OPA in non-dipper patients was significantly lower compared with that of dipper patients (P=0.011). There was no significant difference in IOP levels between groups. There was no significant difference in the PSV, EDV, RI, and PI in the ophthalmic, posterior ciliary, and central retinal arteries between the groups. CONCLUSION: Our study demonstrated that OPA level in non-dippers is lower than dippers. This may give additional information about the effect of BP changes on OPA values.
