Objective

In this study, we report an experience of 59 natural-cycle IVF combined with in vitro oocyte maturation (IVF/M) cycles in patients with PCOS requiring IVF recruited based on limitations to afford a conventional IVF treatment in a 9-years period. Results of IVF/M were compared with 164 cycles of IVF in PCOS patients.

Material and methods

In IVF/M cycles only hCG priming was used before oocyte recovery, with in vitro maturation of immature oocytes in a commercial medium. In conventional IVF group, recombinant FSH (rFSH) and GnRH agonist/antagonist for ovarian stimulation were used. In both groups, fertilization was achieved by intracytoplasmic sperm injection (ICSI) of mature oocytes and fresh embryos transferred at day 2 or day 3.

Results

In all IVF/M cycles oocytes and transferable quality embryos were obtained, only in 6 IVF/M cycles mature oocytes were obtained at oocyte capture day. Clinical pregnancy rate per cycle was 39.0% vs 53.6% (p = 0.0682) and delivery rate per cycle was 30.5% vs 42.6% (p = 0.1209) in IVF/M and conventional IVF respectively. Patients with ovarian hyperstimulation syndrome (OHSS) were 0% in IVF/M vs 6.7% in conventional IVF (p = 0.0399).

Conclusion

Our experience in a private clinic in Mexico suggests that IVF/M can be a useful initial strategy to treat PCOS patients requiring IVF with comparable delivery rates to conventional IVF and a decreased risk of ovary hyperstimulation. IVF/M may be indicated to patients with limited resources paying without insurance for their infertility treatment.  相似文献

Objective

Ovarian hyperstimulation syndrome (OHSS) is a major complication of assisted reproductive technologies (ART). Polycystic ovary syndrome (PCOS) is a risk factor for OHSS. The aim of this randomized clinical trial (RCT) was to study the effect of low-dose aspirin (LDA) on the development of OHSS and ART outcomes in PCOS during ART.

Materials and methods

This double-blinded placebo controlled RCT was performed on 232 PCOS infertile women in their first ART cycles during 2010–2016. LDA and placebo capsules were prepared, packed and specified by code numbers in similar shapes. One package was given to every woman and asked to take one capsule/day since the 21st day of her cycle prior to the gonadotropin stimulation. Gonadotropin releasing hormone agonist long protocol and triggering by human chorionic gonadotropin were used. Development of moderate to severe OHSS and their ART outcomes were documented then the codes were broken and data analyzed. Chi-square and Mann–Whitney U tests were used for the statistical analyses.

Results

Eighteen cases that did not follow the study design were excluded. 214 cycles remained for the final analyses with 109 cases in LDA and 105 in the placebo group. Rate of the moderate to severe OHSS in LDA group was 34.9% compared to 30.5% in placebo group (P = 0.494). Fertilization rate was 71.8% vs 65.1% (P = <0.001) and the mean number of grade III embryos were 3.28 ± 3.53 vs 1.46 ± 1.42 (P = 0.014) in LDA and placebo groups, respectively. The mean number of the oocytes in different grades, total and frozen embryos also implantation and clinical pregnancy rates were not different between the groups.

Conclusion

Moderate to Severe OHSS was not decreased but fertilization rate and the mean number of poor quality embryos were increased in LDA arm.

Introduction

Sexual dysfunction occurs in any phase of sexual performance or any period of the sexual response cycle, and polycystic ovary syndrome (PCOS) affects self-image with repercussions on sexuality.

Aim

To evaluate sexual dysfunction in women with PCOS.

Methods

A systematic review was undertaken following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. The primary databases MEDLINE, EMBASE, Cochrane, and Lilacs were accessed using specific terms. There was no constraint against year of publication. The meta-analysis was conducted with RevMan program version 5.3.

Main Outcome Measure

We evaluated the relationship between sexual dysfunction and PCOS.

Results

The systematic review encompassed 19 studies. The analysis indicated that 11 specific and 6 general instruments were used to measure the sexual function in PCOS women. Of these, the Female Sexual Function Index scale was used most frequently. All studies assessed different aspects of sexual performance in PCOS women, and no difference was found in between women with PCOS and control subjects.

Clinical Implications

Although there were disparities regarding ethnicity, culture, religion, and economy among studies, the available evidence failed to prove a significant link between PCOS and sexual dysfunction.

Strength & Limitations

This systematic review addressed a multidimensional theme with many variables and with a wide diversity of measurement tools. Studies were small, and populations were not homogeneous.

Conclusion

Despite potential risk of bias, such as inhomogeneity of study population, sexual function of both PCOS patients and women with regular menstrual cycles might, in general, be similar.Firmino Murgel AC, Santos Simões R, Maciel GAR, et al.

Study Objective

To compare ovarian function between adolescents conceived using assisted reproductive technology (AcART) and adolescents who were conceived spontaneously (AcSP).

Design

Multicenter study of ovarian function in AcART because of male or tubal infertility.

Setting

University Hospital.

Participants

We evaluated 22 AcART and 53 AcSP at 1-2 years after menarche. The participants were born at term (≥37 weeks of gestation) with normal birth weights (≥2500 g) from singleton pregnancies.

Interventions

None.

Main Outcome Measures

Differences in ovulation, reproductive hormones, and ovarian morphology.

Results

AcART had an older age of menarche than that of AcSP, even after adjusting for maternal age at menarche, gestational age, and birth weight (P = .027). AcART had lower incidence of ovulation (P = .021) and higher luteinizing hormone serum levels (P = .01) than those of AcSP. The incidence of oligomenorrhea and the cycle length were similar between AcART and AcSP. AcART had levels of anti-Müllerian hormone, inhibin B, follicle-stimulating hormone, estradiol, and androgens similar to those of AcSP. The ovarian morphology, ovarian volume, and follicle counts were similar in both groups.

Conclusion

AcART had later menarche, lower ovulation rates, and higher luteinizing hormone levels than those of AcSP. Future studies should investigate whether these findings are indicative of a risk of ovarian dysfunction later in life for AcART.  相似文献

Objective

To examine whether delayed newborn bathing would increase rates of in-hospital exclusive breastfeeding and plans to use human milk at discharge.

Design

A retrospective, two-group, pre- and postintervention design.

Setting/Local Problem

At our facility, the initial bath was completed within 2 hours of birth, and the rate of in-hospital exclusive breastfeeding was low.

Participants

Couplets of mothers and healthy newborns (N = 996).

Intervention/Measurements

Newborn baths were delayed at least 12 hours after birth. Pre- and postintervention data were retrieved from the hospital’s electronic medical record and administrative database. Univariate and multivariate analyses were completed.

Results

Of 996 mother–newborn couplets, 448 were preintervention couplets and 548 were postintervention couplets. Of all mothers, 63.3% were White, 67.8% were married, and 67.1% gave birth vaginally. Of all newborns, 49.6% were female, and the mean (standard deviation) birth weight was 3.3 kg (0.50). We found no differences in maternal or newborn characteristics by group. Median (25th percentile, 75th percentile) times from birth to first bath before and after the intervention were 1.9 (1.6, 2.3) and 17.9 (11.9, 25.0) hours, respectively (p < .001). In-hospital exclusive breastfeeding increased from 59.8% before the intervention to 68.2% after the intervention (p = .006). In multivariate modeling, in-hospital exclusive breastfeeding increased for all couplets after the intervention (odds ratio = 1.49, 95% confidence interval [1.14, 1.96]; p = .004) and with vaginal versus cesarean birth (odds ratio = 1.60, 95% confidence interval [1.14, 2.25]; p = .006). In addition, the postintervention discharge feeding plan reflected an increase in use of human milk.

Conclusion

Delaying the newborn bath was associated with increased in-hospital exclusive breastfeeding rates and use of human milk as a part of the discharge feeding plan.  相似文献

Study Objective

The objective of this study was to describe prevalence and location of obstetric lacerations in adolescents.

Design

Retrospective cohort study.

Setting

We performed an analysis of the Consortium on Safe Labor database including tertiary care university-affiliated urban hospitals.

Participants

All primiparous women who delivered vaginally were included.

Interventions

Vaginal and perineal lacerations were compared between age groups 15 or younger, 16-21, 22-34, 35-39, and older than 40 years.

Main Outcome Measures

Outcome measures included vaginal, perineal, labial, and periurethral lacerations. χ2 and Fisher exact tests were used as appropriate, with P < .05 considered significant.

Results

A total of 9777 patients were included in the analysis. Young adolescents and adolescents had significantly higher rates of labial and periurethral lacerations compared with individuals aged 22-34 years. The prevalence of third- and fourth-degree perineal tears increased with age.

Conclusion

Adolescent primiparous women are less likely to have severe perineal obstetric tears, but have higher rates of labial and periurethral tears.  相似文献

Introduction

Erectile function, an important aspect of quality of life, is gaining increased research and clinical attention in older men with hypertension.

Aim

To assess the cross-sectional association between blood pressure measures (systolic blood pressure [SBP]; diastolic blood pressure [DBP]; and pulse pressure [PP]) and (i) sexual activity and (ii) erectile function in hypertensive men.

Methods

We performed analyses of 1,255 male participants in a larger randomized clinical trial of 9,361 men and women with hypertension aged ≥50 years.

Main Outcome Measures

The main outcome measures were self-reported sexual activity (yes/no) and erectile function using the 5-item International Index of Erectile Function (IIEF-5).

Results

857 participants (68.3%) reported being sexually active during the previous 4 weeks. The mean (SD) IIEF-5 score for sexually active participants was 18.0 (5.8), and 59.9% of the sample reported an IIEF-5 score <21, suggesting erectile dysfunction (ED). In adjusted logistic regression models, neither SBP (adjusted odds ratio = 0.998; P = .707) nor DBP (adjusted odds ratio = 1.001; P = .929) was significantly associated with sexual activity. In multivariable linear regression analyses in sexually active participants, lower SBP (β = ?0.04; P = .025) and higher DBP (β = 0.05; P = .029) were associated with better erectile function. In additional multivariable analyses, lower PP pressure was associated with better erectile function (β = ?0.04; P = .02).

Clinical Implications

Blood pressure is an important consideration in the assessment of erectile function in men with hypertension.

Strengths & Limitations

Assessments of blood pressure and clinical and psychosocial variables were performed using rigorous methods in this multi-ethnic and geographically diverse sample. However, these cross-sectional analyses did not include assessment of androgen or testosterone levels.

Conclusions

Erectile dysfunction was highly prevalent in this sample of men with hypertension, and SBP, DBP, and PP were associated with erectile function in this sample.Foy CG, Newman JC, Berlowitz DR, et al.

Objective

To evaluate the effect of the Premature Infant Oral Motor Intervention (PIOMI) on preterm newborns’ feeding efficiency and rates of improvement across Days 1, 3, and 5 of oral feeding in a Thai NICU.

Design

Randomized controlled trial.

Setting

A 20-bed special neonatal ward and 8-bed NICU in urban Thailand.

Participants

Stable newborns (N = 30) born between 26 and 34 weeks postmenstrual age (PMA) without comorbidities.

Methods

After they reached 32 to 34 weeks PMA, participants were randomly assigned to groups. The experimental group (n = 15) received the PIOMI once daily for 7 consecutive days, and the control group (n = 15) received routine care only. After oral feedings were initiated, the mean volume (MV) of oral intake of two consecutive oral feedings was calculated on Days 1, 3, and 5 to assess feeding efficiency and compare the groups.

Results

The MV of oral intake (percentage of prescribed feeding) was significantly greater in the experimental group versus the control group on all days of measurement. The MV consumed on Day 1 of oral feeding was 44.9% ± 7.33% in the experimental group versus 29.7% ± 9.55% in the control group (P < .001), 53.9% ± 8.01% versus 30.4% ± 11.07% on Day 3 (P < .001), and 61.7% ± 7.44% versus 34.8% ± 8.76 on Day 5 (P < .001). The rate of improvement was also accelerated in the intervention group.

Conclusion

The improved feeding efficiency that we found in our participants is consistent with results from other published studies and supports the use of the PIOMI as an effective oral motor therapy for newborns ages 32 to 34 weeks PMA.  相似文献

Objective

The primary objective of this study was to investigate whether preimplantation genetic testing for aneuploidy (PGT-A) of blastocysts through array comparative genomic hybridization (aCGH) improves live birth rates (LBR) in IVF cycles for patients with high prevalence of aneuploidy.

Materials and Methods

This study included 1389 blastocysts with aCGH results derived from 296 PGT-A cycles in IVF patients with advanced maternal age (AMA) (n = 87, group A), those with repeated implantation failure (RIF) (n = 82, group B), those with recurrent miscarriage (RM) (n = 82, group C), and oocyte donors (OD) (n = 45, young age, as a control group). Another 61 AMA patients without PGT-A procedures were used as a control group for group A. Vitrification was performed after blastocyst biopsy, and thawed euploid embryos were transferred in a nonstimulated cycle.

Results

For the AMA group, a significant increase in LBRs was found in the PGT-A group compared with the non–PGT-A group (54.1% vs. 32.8%, p = 0.018). Consistent LBRs (54.1%, 51.6%, 55.9%, and 57.1%, respectively, in group A, B, C, and young age group) were obtained for all the indications.

Conclusions

LBRs can be improved using PGT-A of blastocysts with aCGH in IVF cycles for patients with a high rate of aneuploidy, especially for patients with AMA.  相似文献

Background

Mounting evidence has emerged suggesting that patients with Parkinson’s disease (PD) are susceptible to sexual dysfunction (SD).

Aim

To better clarify the relationship between PD and SD.

Methods

PubMed, Embase, Cochrane Library database, and PsychINFO database were systematically searched for pertinent studies evaluating sexual function in the patients with PD. This systematic review and meta-analysis have been registered on PROSPERO (ID: CRD42018108714; http://www.crd.york.ac.uk/PROSPERO).

Outcomes

The association between PD and SD was assessed using relative risk (RR) with 95% CI. The quality of evidence was ranked by the GRADE profiler.

Results

11 observational studies met the predefined criteria for inclusion, enrolling 30,150 subjects from both the PD group and healthy control group (mean age 54.6–75.1 years). Synthesis results revealed that PD was associated with an elevated risk of SD in males (7 studies; 1.79; 95% CI = 1.26–2.54, P = .001; heterogeneity: I2 = 73.2%, P < .001). However, when restricted to female subjects, the combined RR from 3 eligible studies suggested a lack of significant association between PD and SD (RR = 1.3, 95% CI = 0.64–2.61, P = .469; heterogeneity: I2 = 80.0%, P = .007). The GRADE profiler indicated the overall quality of the evidence was low in studies including males and very low in studies including females.

Clinical Implications

The current meta-analysis indicated that men with PD were more likely to experience SD than those without PD. In female subjects, however, PD seemed to not be associated with a high prevalence of SD compared with healthy controls. Based on these findings, patients with PD should be routinely assessed for sexual functioning, especially males.

Strengths & Limitations

This is the first systematic review and meta-analysis of the association between PD and the risks of SD in both males and females. However, substantial heterogeneities were detected across the included studies.

Conclusion

A hazardous effect of PD for developing SD was detected in men but not in women. As a result, sexual function assessment and appropriate therapy are recommended for men with PD in clinical practice.Zhao S, Wang J, Xie Q, et al.

Introduction

Comparative studies on differences in sexual function outcomes between homosexual and heterosexual men are sparse and inconclusive.

Aim

To systematically evaluate whether, and to what extent, a statistically significant difference exists in the odds of erectile dysfunction (ED) and premature ejaculation (PE) between homosexual and heterosexual men.

Methods

A thorough search of Medline, SCOPUS, CINAHL, and Web of Science databases was carried out to identify case-control studies comparing the prevalence of ED and PE in homosexual and heterosexual men. Methodological quality of the included studies was assessed using the Newcastle-Ottawa Scale. Odds ratios (ORs) of reporting ED and PE were combined using random effect models. The Cochrane Q and I2 tests were carried out to analyze the between-studies heterogeneity. Funnel plots and trim-and-fill analysis were used to assess publication bias.

Main Outcome Measures

The relationship between sexual orientation and odds of ED and PE was assessed by calculating pooled ORs with a 95% CI.

Results

4 studies included in the quantitative analysis collectively provided information on 1,807 homosexual and 4,055 heterosexual men. The pooled ORs indicated that homosexual orientation was associated with 1.5-fold higher odds of reporting ED (OR = 1.49, 95% CI = 1.03–2.16; P = .04) and 28.0% lower odds of reporting PE in comparison to the heterosexual orientation (OR = 0.72, 95% CI = 0.52–1.00; P = .05). However, a significant heterogeneity among the studies was observed. Funnel plots revealed a possible publication bias only for the ED analysis, where the trim-and-fill test detected a putative missing study. Nevertheless, even when the pooled estimate was adjusted for publication bias, there was a significantly higher risk of ED in the homosexual group (adjusted OR = 1.60, 95% CI = 1.10–2.30; P = .01).

Clinical Implications

These findings can drive future studies on sexual needs and concerns of homosexual men, which might not exactly match those of heterosexual individuals.

Strength & Limitations

This is the first meta-analysis exploring the differences in the prevalence of ED and PE between homosexual and heterosexual men. However, the results should be interpreted with caution, because their generalization could be hindered by the non-probabilistic nature of the samples, and a measurement bias could result from the use of different non-standardized indicators of sexual dysfunctions.

Conclusion

Homosexual orientation is associated with higher odds of ED and lower odds of PE compared with heterosexual orientation. Further studies are warranted to elucidate the clinical significance of these findings and whether they reflect differences in patterns of sexual lifestyle.Barbonetti A, D’Andrea S, Cavallo F, et al.

Background

Hypersexual disorder (HD) is defined as a condition in which the individual loses control over engagement in sexual behaviors, leading to distress and negative effects on key life areas. Cognitive behavioral therapy (CBT) has been proven to reduce symptoms of hypersexual behavior; however, no randomized controlled study of CBT interventions for HD has been reported previously.

Aim

To investigate the efficacy of group-administered CBT for HD.

Methods

Male participants (n = 137) diagnosed with HD, were randomized between 7 weeks of group-administered CBT (n = 70) and a waitlist control receiving the intervention after 8 weeks (n = 67). Measurements were administered at pre-, mid-, and posttreatment, with follow-up after 3 and 6 months.

Outcomes

The primary outcome was the Hypersexual Disorder: Current Assessment Scale (HD:CAS), and secondary outcomes were the Sexual Compulsivity Scale (SCS) and measures of depression (Montgomery–Åsberg Depression Rating Scale (MADRS-S), psychological distress (Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM), and treatment satisfaction (CSQ-8).

Results

A significantly greater decrease in HD symptoms and sexual compulsivity, as well as significantly greater improvements in psychiatric well-being, were found for the treatment condition compared with the waitlist. These effects remained stable at 3 and 6 months after treatment.

Clinical Implications

CBT can ameliorate HD symptoms and psychiatric distress, suggesting that the CBT program may serve as a first-line treatment in clinical settings.

Strengths & Limitations

This is the first randomized controlled study evaluating the efficacy of a CBT program in a rather large sample of HD-specific diagnosed men. The long-term treatment effects are vague due to the low response rate on follow-up measurements, and the efficacy of this program for hypersexual women remains unknown.

Conclusion

This study supports the efficacy of a group-administered CBT program as a treatment option for HD; however, future studies should include women, comprise dismantling analysis of the constituting interventions, and evaluate other treatment formats, for example, administration via the Internet.Hallberg J, Kaldo V, Arver S, et al.

Study Objective

To assess the knowledge and beliefs regarding human papillomavirus (HPV) and the HPV vaccine among girls before and after vaccination in the Malaysian HPV Immunisation Programme.

Design

A nationwide longitudinal survey.

Setting

Thirty-two randomly selected schools from 13 states and 3 federal territories in Malaysia from February to March 2013, and October to November 2013.

Participants

Form One female students (13 years old).

Interventions

None.

Main Outcome Measures

Mean knowledge score of HPV infection.

Results

A total of 2644 students responded to the prevaccination survey, of whom 2005 (70%) completed the postvaccination survey. The mean knowledge score was 2.72 (SD ± 2.20) of a maximum score of 10 in the prevaccination survey, which increased significantly to 3.33 (SD ± 1.73) after the 3 doses of HPV vaccine (P = .001). Many answered incorrectly that, “Only girls can get HPV infection” (91.5%, n = 1841 prevaccination vs 96.1%, n = 1927 postvaccination), and only a few were aware that, “Vaccinating boys helps to protect girls against HPV infection” (11.4%, n = 229 for prevaccination vs 10.2%, n = 206 for postvaccination). The mean knowledge score was significantly higher postvaccination among higher-income families and those with parents of a higher occupational status. Regarding beliefs about the HPV vaccine, 89.4% in the prevaccination survey held the view that they would not get a HPV infection, and the percentage remained similar in the postvaccination survey. Perceived severity of HPV infection also remained low in the pre- and postintervention groups. Only 21.5% reported receiving health information about HPV along with the provision of the HPV vaccine; those who received health information showed higher levels of knowledge.

Conclusion

Findings revealed a general lack of knowledge and erroneous beliefs about HPV and the HPV vaccine even after receiving vaccination. This suggests that imparting accurate knowledge about HPV along with vaccine administration is essential. Specifically, girls from lower socioeconomic groups should be a target of educational intervention.  相似文献

Introduction

One factor that may plausibly be associated with sexual dysfunction is sleep disturbance. Like sexual problems, complaints of sleep disturbance increase with age and are commonly reported by older adults.

Aims

To examine associations between sleep quality, duration, and a range of sexual problems in a large, representative sample of older adults.

Methods

Data were from 2,568 men and 1,376 women (age ≥50 years) participating in Wave 6 of the English Longitudinal Study of Ageing (2012–2013). Sleep quality, duration, and problems with erectile function, sexual arousal, and orgasmic experience were self-reported; associations were examined using logistic regression models. Covariates included age, ethnicity, partner status, wealth, limiting long-standing illness, smoking, alcohol consumption, physical activity, and depressive symptoms.

Main Outcome Measure

Participants self-reported problems with erectile function, sexual arousal, and orgasmic experience.

Results

In women, moderate (odds ratio [OR] = 1.53, 95% CI 1.09–2.13, P = .013) and low sleep quality (OR = 1.70, 95% CI 1.24–2.32, P = .001) were associated with increased odds of arousal problems relative to high sleep quality. In men, moderate sleep quality was associated with increased odds of erectile difficulties (OR = 1.47, 95% CI 1.16–1.85, P = .001), the difference between low and high sleep quality did not reach statistical significance (OR = 1.24, 95% CI 0.97–1.58, P = .091). Sleep quality was not associated with difficulty achieving an orgasm in men, but in women low sleep quality was associated with increased odds of orgasmic difficulty (OR = 1.63, 95% CI 1.18–2.25, P = .003). No associations between sleep duration and problems with sexual function were observed in women, but, in men, long sleep was associated with higher odds of difficulty achieving orgasm (OR = 1.75, 95% CI 1.04–2.95, P = 0.036) relative to optimal sleep duration.

Clinical Implications

Older adults presenting sleep problems should be screened for sexual dysfunction and vice versa.

Strength & Limitations

Strengths of this study include the large representative sample of older English adults, the assessment of several aspects of sexual dysfunction and sleep, and the inclusion of potentially important confounding variables into statistical models. However, the study was cross-sectional, meaning we were unable to ascertain the direction of the observed associations.

Conclusion

Sleep problems are associated with sexual dysfunction in older English adults, although some variation is noted between men and women.Smith L, Grabovac I, Veronese N, et al. Sleep Quality, Duration, and Associated Sexual Function at Older Age: Findings From the English Longitudinal Study of Ageing. J Sex Med 2019;16:427–433.  相似文献

Introduction

The efficacy and safety of arginine supplements in erectile dysfunction (ED) remain debatable.

Aim

To assess the potential role of arginine supplements on ED as alternatives to phosphodiesterase inhibitors.

Methods

Studies published up to April 2018 that evaluated the efficacy of arginine supplements were identified from multiple databases (Google Scholar, PubMed, Medline, Embase, Kiss, DBpia, and Cochrane databases). Studies comparing arginine supplements with placebo or no treatment; focusing only on patients with mild to moderate severity of ED; and presenting outcomes such as improvement rate, International Index of Erectile Function (IIEF) score, and adverse effects were included. Subgroup analysis for arginine alone and arginine in combination with other substances was further conducted to increase interpretability.

Main Outcome Measure

The strength of the association between arginine supplements and ED was assessed using relative odds ratios and weighted mean differences with 95% CI.

Results

In total, 10 randomized controlled trials met the inclusion criteria, reporting the outcomes of 540 patients with ED. The analysis demonstrated that arginine supplements with dosage ranging from 1,500 to 5,000 mg significantly improved ED compared with placebo or no treatment (odds ratios, 3.37 [1.29, 8.77], P = .01, I2 = 44). Arginine supplements also caused significant improvements in the IIEF subdomain scores of overall satisfaction, intercourse satisfaction, orgasmic function, and erectile function, whereas the IIEF sexual desire score remain unchanged. The adverse effect rate in the arginine-treated group was 8.3%, and that in the placebo group was 2.3%, none of which were severe.

Clinical Implications

Arginine supplements can be recommended to patients with mild to moderate ED.

Strength & Limitations

The strength of this study is that it is the first meta-analysis to assess the potential role of arginine supplements in ED compared with placebo or no treatment. A limitation is that the treatment dosage and duration varied among studies, which may have contributed to study heterogeneity.

Conclusion

The results of our systematic review and meta-analysis provide evidence on the effectiveness of arginine supplements for mild to moderate ED.Rhim HC, Kim MS, Park Y-J, et al.

Objective

To explore the relationships among young women’s demographic characteristics, their self-perceived and actual knowledge about fertility, and their fertility health risk factors.

Design

A quantitative, cross-sectional study.

Setting

Online survey.

Participants

Young women between the ages of 18 and 24 years (N = 342).

Methods

We used an online survey to collect data from young women regarding their demographic characteristics, their self-perceived and actual knowledge about fertility, and their fertility health risk factors. We used multiple linear regression to explore the relationships among these factors.

Results

Participants were mainly White, had some form of college education, and used a variety of contraception methods. Regression modeling indicated that participants’ self-perceived knowledge and actual knowledge about fertility and their methods of contraception were significantly associated with their fertility health risks (R2 = .13, p < .001). Participants who had higher actual scores of knowledge about fertility and who used fertility awareness methods had fewer self-reported fertility health risk factors. A greater level of self-perceived knowledge about fertility was associated with more fertility health risk factors. Age, education level, and pregnancy history were not significantly associated with fertility health risks.

Conclusion

Our findings provide evidence that knowledge about fertility is important to enhance fertility self-care for young women. The significant relationship between young women’s knowledge about fertility and their fertility health risks highlights the need to assess their knowledge and teach them about fertility as important components of preconception care. Such education may help them avoid fertility health risks and protect young women’s current and future fertility.  相似文献

To quantify vitamin D status among pregnant women in the Pacific Northwest (Portland, OR, and Seattle, WA) and examine pregnancy and newborn outcomes in relationship to maternal serum blood samples obtained during pregnancy.

Design

A retrospective cohort design.

Setting

Data from 2009 to 2013 were abstracted from the health records of two out-of-hospital midwifery practices in the Pacific Northwest.

Participants

Women with recorded serum blood samples for vitamin D during pregnancy were included. We reviewed health records of 663 women, and 357 met criteria.

Methods

We extracted demographic, biometric, and pregnancy outcome data from participants’ records and analyzed them using regression models.

Results

Mean serum 25-hydroxy vitamin D (25[OH]D) was 29.96 ± 10.9 ng/ml; 45.5% of participants were sufficient (≥30 ng/ml), and 55.5% were insufficient or deficient (<29 ng/ml). Lower vitamin D levels were predicted by Seattle location, greater prepregnancy body mass index, and blood samples drawn during the winter. Vitamin D status was not a predictor of spontaneous abortion, glucose tolerance test result, cesarean birth, infant birth weight, or any other outcome investigated.

Conclusion

Although there is a high prevalence of vitamin D insufficiency and deficiency in pregnant women in the Pacific Northwest, adverse health effects were not observed. This may be attributable to the overall healthy profile of the women in our sample. Further research on maternal vitamin D status should focus on identification of optimal vitamin D levels in pregnancy and long-term outcomes among offspring of women who are vitamin D deficient, particularly those from high-risk, vulnerable populations.  相似文献

Introduction

Spontaneous penile tumescence after penile prosthesis implantation has been sporadically reported in the literature.

Aim

To preserve residual erectile function of patients’ spontaneous penile tumescence by sparing cavernous tissue in the course of malleable penile prosthesis implantation.

Methods

Overall, 92 patients were randomized into 2 equal arms; patients undergoing conventional malleable penile prosthesis implantation, and patients undergoing the cavernous tissue–sparing technique. 1 month after surgery, these patients underwent penile duplex examination to assess the maximal cavernous tissue thickness around the implant cylinders. Additionally, they were asked about the occurrence of any spontaneous or arousal-induced penile tumescence.

Main Outcome Measures

Postoperative changes were compared with the preoperative ones.

Results

The mean maximal cavernous tissue thickness was shown to be significantly higher in the cavernous tissue–sparing group compared with the conventional surgery group (5.2 ± 0.8 mm vs 2.2 ± 1.04 mm, P < .01). In the cavernous tissue–sparing group, 41 of 46 patients (89.13%) reported having a significantly higher incidence of residual penile tumescence vs 7 of 46 patients (15.2%) in the conventional surgery group (P < .001). The postoperative penile girth was significantly higher in the cavernous tissue–sparing group than in the conventional surgery group (11.16 ± 1.1 cm vs 10.11 ± 1.15 cm, P < .001).

Clinical Implications

This study provides a step-by-step approach to maintaining post-implantation penile tumescence and preserving penile girth in a reproducible manner.

Strengths & Limitations

This is the first study to demonstrate the benefits of implanting a penile prosthesis while the penis is in a pharmacologically induced tumescent state. It is also the first to make use of ultrasound imaging in assessing postoperative corporal tissue. The main limitations are the short postoperative follow-up period and the non-blinding of measurements.

Conclusion

It could be concluded that the cavernous tissue–sparing technique is a reproducible technique that has the added value of preserving residual erectile function in the form of retained postoperative penile tumescence and preserved penile girth.Zaazaa A, Mostafa T.
