RESUMO

The presence of hazardous agents in workplaces has raised concerns regarding their possible impacts on male reproductive system. The present study investigated the individual and combined effects of exposure to heat stress and electromagnetic fields with low-frequency characteristics on the levels of sex hormones in two foundry sections (Aluminum and Cast Iron) of an automobile parts manufacturing plant. The level of workers' exposure (n = 110) to each of the mentioned stressors, was measured through standard methods and for each person and the time-weighted average (TWA) of exposure was calculated. The participants of each sections were classified into separate exposure groups based on the 33rd and 66th percentile of the level of to heat stress and electromagnetic fields exposure. In order to determine serum sex hormones, blood samples were taken from all participants between 7-9 am and then the blood samples were analyzed by ELISA method. In total of two sections, the lowest mean testosterone levels was observed in the third exposure group of the electromagnetic fields (magnetic field>1.40 µT; electric field >0.42 V/m), however, the mean difference in testosterone levels between the three different groups of exposure wasn't statistically significant (P > 0.05). According to the results of Logistic Regression, the electric field had the greatest effect on testosterone levels as the main male hormone. Drawing a definitive conclusion regarding the effects of each harmful physical hazards is difficult due to the existence of psychological stressors and other environmental stressors such as chemical pollution, ergonomic hazards and other physical stressors.

RESUMO

PURPOSE: Obstructive sleep apnea is characterized by repetitive cessation of breathing during sleep. It affects different aspects of sexuality. We aimed to assess male sexual function & risk factors in obstructive sleep apnea patients. METHODS: This case control study included 2 groups, 45 healthy volunteers as control group and 45 patients with confirmed diagnosis of obstructive sleep apnea. All the participants were subjected to measurement of Body Mass Index, Full night polysomnography (only for patients group) and serum total testosterone, FSH and LH. The International Index of Erectile Function-5 and Hamilton Depression Scale questionnaires were filed out for all participants. RESULTS: The mean scores for all sexual domains were significantly lower among the patients group compared to the control group (p<0.01). The Hamilton score was significantly higher among the patients group compared to the control group (p<0.0001). The mean levels of Testosterone and LH were significantly lower among the patients group compared to controls (p<0.0001), There were significant correlations between disease severity and age (r=0.48, p=0.001), Body mass index (r=0.48, p=0.001), Hamilton score (r=0.34, p=0.014) International Index of Erectile Function 5 domain score (r= -0.29, p=0.045)Testosterone level (r= -0.29, p=0.046) and LH levels (r= -0.104, p=0.049). CONCLUSION: We found that all domains of sexual function have been affected in patients group than controls. Their score was inversely related to the disease severity; which in turn has a complex interaction with other factors like age, obesity, hormones and psychological status. So when evaluating those patients, sexual dysfunction should be considered and assessed along with these factors.

RESUMO

Differences of Sex Development (DSD) comprise a variety of congenital conditions characterized by atypical chromosomal, gonadal, or anatomical sex. Diagnosis and monitoring of treatment of patients suspected of DSD conditions include clinical examination, measurement of peptide and steroid hormones, and genetic analysis. This position paper on peptide hormone analyses in the diagnosis and control of patients with DSD was jointly prepared by specialists in the field of DSD and/or peptide hormone analysis from the European Cooperation in Science and Technology (COST) Action DSDnet (BM1303) and the European Reference Network on rare Endocrine Conditions (Endo-ERN). The goal of this position paper on peptide hormone analysis was to establish laboratory guidelines that may contribute to improve optimal diagnosis and treatment control of DSD. The essential peptide hormones used in the management of patients with DSD conditions are follicle-stimulating hormone, luteinising hormone, anti-Müllerian hormone, and Inhibin B. In this context, the following position statements have been proposed: serum and plasma are the preferred matrices; the peptide hormones can all be measured by immunoassay, while use of LC-MS/MS technology has yet to be implemented in a diagnostic setting; sex- and age-related reference values are mandatory in the evaluation of these hormones; and except for Inhibin B, external quality assurance programs are widely available.

RESUMO

BACKGROUND: To investigate the effectiveness and safety of 3 mg drospirenone and 20 µg ethinyl estradiol tablet (3 mg DRSP/20 µg EE) in the treatment of polycystic ovary syndrome (PCOS). METHODS: This single center, prospective observational study was conducted in 140 patients with PCOS. They were prescribed 3 mg DRSP/20 µg EE in a 24/4/ regimen for 3 months. Patients were instructed to take oral DRSP/EE tablets (once daily) on the 2nd day of menstruation, for 28 consecutive days for 1 cycle. After 3 months of treatment, anthropometric assessments along with variations in sex hormones related index, glucolipid metabolic index, changes in bilateral ovarian volume, as well as adverse effect of the combination were evaluated. RESULTS: When compared to baseline, body mass index (BMI, 22.07 ± 4.09 vs. 21.35 ± 3.22, p < 0.001) and waist hip ratio (WHR, 0.86 ± 0.07 vs. 0.854 ± 0.06, p = 0.026) decreased significantly after treatment. Sex-hormones such as luteinizing hormone (LH) (10.88 vs. 5.81 U/L), testosterone (T) (1.85 vs. 1.51 nmol/L) and free androgen index (FAI) (5.37 vs. 1.50) decreased significantly after treatment (p < 0.001). Follicular stimulating hormone (FSH) increased significantly at 3 months as compared to before treatment (5.13 vs. 5.42 U/L, p = 0.009). Plasma insulin (11.03 vs. 11.10 pmol/L), fasting (4.97 vs. 4.93 mmol/L) and 2 h-blood glucose levels (7.18 vs. 7.04 mmol/L) did not change when compared to baseline. Plasma triglycerides (TG, 1.32 vs. 1.65 mmol/L) significantly increased 3 months after treatment when compared to before treatment (p < 0.001). However, high density lipoprotein-cholesterol (HDL-C) levels increased significantly after treatment (1.41 vs. 1.57 mmol/L, p < 0.001). It was seen that, when compared to baseline, bilateral ovarian volume (left and right) was significantly lower after treatment (p < 0.05). It was seen that 81 patients reported no adverse reactions. Of the common discomforts reported, breast swelling and pain, gastrointestinal disorder and dizziness and headache were most frequent. CONCLUSIONS: Treatment of PCOS patients with3 mg DRSP/20 µg EE has shown beneficial hormonal and lipid profile along with considerable safety profile. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR1900022001, March 2019, retrospectively registered.

RESUMO

INTRODUCTION: Current health literature suggests that there has been a decline in the age of pubertal onset and that pubertal onset/duration of puberty may, besides weight status, be influenced by socioeconomic context. OBJECTIVE: The goal of this study was to determine whether pubertal onset/duration and puberty-triggering hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH) vary according to socioeconomic status (SES). Moreover, we aimed to propose cutoff values of serum LH and FSH for predicting gonadarche in boys. METHODS: 2,657 apparently healthy children and adolescents between 5.5 and 18 years from the area of Leipzig were recruited from the LIFE Child study. Age at pubertal onset/end of puberty was given in 738/573 children, respectively. Anthropometric parameters of puberty, blood measurements of LH and FSH, and questionnaires assessing SES were evaluated. RESULTS: Lower SES was associated with earlier thelarche and longer duration of puberty in overweight/obese girls, whereas age of menarche was not affected. In boys with low SES, a trend versus earlier puberty onset can be seen. Lower SES was significantly associated with boys' age at mutation. No significant differences in boys' and girls' serum levels of LH and FSH during puberty according to SES were observed. Serum LH levels of 0.56 IU/L and serum FSH levels of 1.74 IU/L showed the best prediction of gonadarche in boys. CONCLUSION: Puberty onset/duration and boys' age at mutation is affected by SES. The proposed cutoff levels for serum LH and FSH could provide a serological tool to determine gonadarche in boys.

RESUMO

OBJECTIVE: To describe the prevalence of Y-chromosome microdeletions in a multi-ethnic urban population in London, UK. To also determine predictive factors and a clinical threshold for genetic testing in men with Y chromosome microdeletions. PATIENTS AND METHODS: A retrospective cohort study of 1473 men that were referred to a tertiary Andrology centre with male factor infertility between July 2004 and December 2016. All had a genetic evaluation, hormonal profile and 2 abnormal semen analyses. Those with abnormal examination findings also had targeted imaging performed. RESULTS: The prevalence of microdeletions was 4% (n = 58) in this study. These microdeletions were partitioned into the following regions: Azoospermia factors (AZF); AZFc (75%), AZFb+c (13.8%), AZFb (6.9%), AZFa (1.7%), and partial AZFa (1.7%). A high follicle-stimulating hormone level (P < 0.001) and a low sperm concentration (P < 0.05) were both found to be significant predictors for the identification of a microdeletion. Testosterone level, luteinising hormone level and testicular volume did not predict the presence of a microdeletion. None of the men with an AZF microdeletion had a sperm concentration of >0.5 million/mL. Lowering the sperm concentration threshold to this level retained the high sensitivity (100%) and increased the specificity (31%). This would produce significant cost savings when compared to the European Academy of Andrology/European Molecular Genetics Quality Network and European Association of Urology guidelines. The surgical sperm retrieval (SSR) rate after microdissection testicular sperm extraction was 33.2% in men with AZFc microdeletion. CONCLUSIONS: The prevalence of Y-chromosome microdeletions in infertile men appears to vary between populations and countries. A low sperm concentration was a predictive factor (P < 0.05) for identifying microdeletions in infertile males. A threshold for genetic testing of 0.5 million/mL would increase the specificity and lower the relative cost without adversely affecting the sensitivity. The rate of SSR was lower than that previously described in the literature.

RESUMO

Assisted reproductive technology has evolved tremendously since the emergence of in vitro fertilization (IVF). In the course of the recent decade, there have been significant efforts in order to minimize multiple gestations, while improving percentages of singleton pregnancies and offering individualized services in IVF, in line with the trend of personalized medicine. Patients as well as clinicians and the entire IVF team benefit majorly from 'knowing what to expect' from an IVF cycle. Hereby, the question that has emerged is to what extent prognosis could facilitate toward the achievement of the above goal. In the current review, we present prediction models based on patients' characteristics and IVF data, as well as models based on embryo morphology and biomarkers during culture shaping a complication free and cost-effective personalized treatment. The starting point for the implementation of prediction models was initiated by the aspiration of moving toward optimal practice. Thus, prediction models could serve as useful tools that could safely set the expectations involved during this journey guiding and making IVF treatment more effective. The aim and scope of this review is to thoroughly present the evolution and contribution of prediction models toward an efficient IVF treatment.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Mitragyna speciosa (Korth.) also known as kratom, is a native medicinal plant of Southeast Asia with opioid-like effects. Kratom tea/juice have been traditionally used as a folk remedy and for controlling opiate withdrawal in Malaysia. Long-term opioid use is associated with depletion in testosterone levels. AIM OF THE STUDY: Since kratom is reported to deform sperm morphology and reduce sperm motility, we aimed to clinically investigate the testosterone levels following long-term kratom tea/juice use in regular kratom users. METHODS: A total of 19 regular kratom users were recruited for this cross-sectional study. A full-blood test was conducted including determination of testosterone level, follicle stimulating hormone (FSH) and luteinizing hormone (LH) profile, as well as hematological and biochemical parameters of participants. RESULTS: We found long-term kratom tea/juice consumption with a daily mitragynine dose of 76.23-94.15 mg did not impair testosterone levels, or gonadotrophins, hematological and biochemical parameters in regular kratom users. CONCLUSION: Regular kratom tea/juice consumption over prolonged periods (>2 years) was not associated with testosterone impairing effects in humans.

RESUMO

BACKGROUND This study aimed to investigate ovarian reserve in patients of reproductive age with Celiac disease (CD) using anti-Müllerian hormone (AMH) levels, antral follicle counts (AFCs), and ovarian volume. MATERIAL AND METHODS We included into this study 46 CD female patients and 40 healthy female subjects of reproductive age, ages 18-45 years. Venous blood samples were taken from both groups on days 2-4 of the menstrual cycle, and follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), prolactin (PRL), and AMH levels were measured. On the same day, AFCs and ovarian volumes were determined. Data on body mass index (BMI), gravidity/parity/abortions/alive counts, disease duration, and Marsh histological classification were recorded. RESULTS There were no statistically significant differences between CD and control groups in terms of mean age, BMI, or median gravidity/parity/abortions/alive counts (p>0.05). Also, there were no statistically significant differences between the 2 groups in terms of mean FSH, LH, E2, PRL levels, right and left ovarian volumes, and median right and left ovarian AFCs (p>0.05). However, AMH level was significantly lower in the CD group (p=0.032). No statistically significant correlation was found between AMH levels and age, BMI, FSH, LH, E2, PRL levels, right and left ovarian volumes, right and left ovarian AFCs, or Marsh histological classification using the Spearman correlation test (p>0.05). However, an inverse correlation was detected showing that AMH levels decrease with increasing CD duration (r=-0.054, p=0.001). CONCLUSIONS We found that AMH level and ovarian reserve was decreased in CD patients of reproductive age compared to healthy controls, and that AMH level and ovarian reserve decreased with increasing disease duration in CD patients.

RESUMO

Numerous social and environmental factors (environmental hazards, social factors such as education and career, higher economic status desired before the decision is made to have children) influence a women's decision to postpone pregnancy until late reproductive age. In turn, age is related to a fall in ovarian reserve. The main goal of testing ovarian reserve is the identification of women with so-called diminished ovarian reserve (DOR). Additionally, it provides assistance in the counselling of women who are planning to use assisted reproductive techniques (ART). This review examines current methods of testing ovarian reserve and their application. The most useful methods of assessing ovarian reserve are ultrasonographic count of ovarian antral follicles (AFC) and serum tests of both the anti-Müllerian hormone (AMH) level and the third-day level of follicle stimulating hormone (FSH). However, there are limitations to the currently used methods of testing ovarian reserve, especially in relation to their specificity and sensitivity. It is also difficult to predict egg quality based on these tests. The value of screening programmes of ovarian reserve is yet to be determined.

RESUMO

PURPOSE: Among harmful effects of chemotherapy is the reduction of ovarian function. The aim was to determine the serum levels of FSH, LH, estradiol and AMH after chemotherapy followed by endocrine therapy in breast cancer patients. METHODS: The study included 40 premenopausal hormone receptor-positive breast cancer patients aged 33-50 years. Anthracycline-based chemotherapy received 14/40 while anthracycline-taxane combination received 26/40 of patients, followed by tamoxifen (30/40) or tamoxifen plus goserelin (10/40). All of them experienced chemotherapy-induced secondary amenorrhea. Hormone levels were determined by ELISA. Statistics included Spearman's test, Mann-Whitney test and multiple linear regression analysis. RESULTS: Undetectable AMH levels were observed in 62.5 and 33.3% of patients with time period < 2 and ≥ 2 years from completion of chemotherapy to sample collection. Median levels of hormones for patients treated with anthracycline-based compared to anthracycline-taxane therapy were: 15.5 vs. 22.3 IU/L for FSH; 10.9 vs. 13.6 IU/L for LH; 55.5 vs. 39.5 pg/mL for estradiol; 0.11 vs. 0.11 ng/mL for AMH. The multiple linear regression showed that: women who received goserelin had significantly lower FSH; those with shorter time from completion of chemotherapy to sample collection had significantly higher LH and lower estradiol; younger women had higher AMH levels. CONCLUSIONS: The ovarian function was recovered from chemotherapy-induced secondary amenorrhea with time elapsed since the completion of adjuvant chemotherapy. It may be less disrupted in patients who received anthracycline-based chemotherapy and goserelin plus tamoxifen, as well.

RESUMO

The purpose of this study was to explore the possibility of using a population approach to assessing the risk of reproductive health disorders in women of childbearing age. We observed 240 clinically healthy women aged 20 to 43 years, half of them lived in the Middle Black Earth region of Russia, and 120 women lived in Tajikistan. The study identified population differences in women with different ethnic backgrounds and regions of residence according to a set of genetic, hormonal, and immune signs. All women underwent venous blood sampling for the purpose of HLA typing by molecular genetic analysis and determining the range of normative values ​​of hormonal and immune status parameters. DNA samples were obtained from peripheral blood lymphocytes using reagent kits and a protocol for isolating DNA from various biological materials from DLAtomTM DNAPrep 100 (Russia). Hormonal status was studied in terms of follicle-stimulating hormone, luteinizing hormone, prolactin, estradiol, progesterone, 17-OH-progesterone; Thyroid hormones - thyroid-stimulating hormone, total triiodothyronine, total thyroxine; Androgens - testosterone, dihydroepiandrosterone; Steroid hormone-cortisol. In order to exclude the variability of the data, the examination was carried out on the 3-5th days of the menstrual cycle: luteinizing hormone, follicle-stimulating hormone, estradiol, prolactin, testosterone and on the 20-22nd Day of the progesterone cycle. Statistical data processing was carried out on the basis of SPSS programs and included descriptive and comparative nonparametric statistics, discriminant, regression analysis, one - factorial analysis of variance, calculation of 95% confidence intervals, construction of ROC curves. The study included the determination of allelic variants at the three loci of the HLA-D genes (HLA-DRB1, HLA-DQA1, HLA-DQB1) controlling the immune response. Population differences in the locus of the HLA-DRB1 gene were determined. The HLA-DRB1 * 08 and HLA-DRB1 * 12 alleles are found in the Russian women's population, and the HLA-DRB1 * 04 and HLA-DRB1 * 17 alleles are more reliably detected in the Tajik women's population, while the HLA-DRB1 * 04 allele Is associated with a higher incidence of miscarriage. The population characteristics of the HLA-DQA1 gene locus were also established. In the group of women of the Russian population, the incidence of HLA-DQA1 * 0101 and HLA-DQA1 * 0103 alleles is significantly higher, of which the former is associated with protective properties for reproductive pathology, and the latter, on the contrary, with miscarriage. At the same time, the alleles HLA-DQA1 * 0201 and HLA-DQA1 * 0301 were significantly more often detected in the compared with the population of Tajik women. As in the previous case, for the HLA-DQA1 * 0201 allele reproductive health disorders are not characteristic, and in the case of the HLA-DQA1 * 0301 allele they accompany it. Our studies have revealed that there are differences between the populations of Russian and Tajik women in a number of parameters of the hormonal and immune status, as well as at the level of allelic variants of genes that control the immune response. The population approach, based on the use of discriminant analysis, is a highly effective way of grouping women according to their reproductive health status and the risk factors that caused reproductive damage. The risk factors that caused the reproductive failure are different in combination and manifestation in the populations of Russian and Tajik women, except for the adverse allelic variants of the HLA-DRB1 * 04 and HLA-DQA1 * 0103 genes, which are the same in both populations. The obtained data also show that in different populations in the evaluation of reproductive health a differentiated approach is needed both to establish physiological norms in these categories of parameters and to assess the reproductive health of women.

RESUMO

Data on growth and sexual maturation among boys from the rural Western Cape in South Africa is limited. A cross-sectional study of 269 school boys was conducted testing for serum luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone, sex hormone binding globulin (SHBG) and estradiol (E2); height, weight and body mass index (BMI); sexual maturity (using Tanner Stages) and a questionnaire (demographic and medical history). The median age at pubertal onset (Tanner Stage 2) and Tanner Stage 5 was 11.6 and 14.7 years, respectively. The median testicular volume was 5.5 mL at Tanner Stage 2 increasing from 2.5 mL at Tanner Stage 1 to 14.7 mL at Tanner Stage 5. Height and weight measurements were <25th & 50th percentile references at Tanner Stages 1-3. Controlling for confounders, serum FSH and LH increased (p < 0.05) from Tanner Stage 1 to 4 (by 4.1 and 3 mL respectively), and serum testosterone and estradiol increased after Tanner Stage 2 (by 12.7 nmol/L and 59.5 pmol/L respectively). These results indicate some delays in pubertal development of boys in the rural Western Cape when compared to boys from other settings possibly due to nutritional, socio-economic and environmental exposures. Changes in serum hormone levels were consistent with other populations. Initiatives to improve nutrition amongst Western Cape rural communities are recommended.

RESUMO

BACKGROUND The purpose of this study was to investigate the potential association between socioeconomic status and ovarian reserve, anti-Mullerian hormone level, antral follicle count, and follicle stimulating hormone level in women of reproductive age. MATERIAL AND METHODS A total of 101 married women between 20-35 years of age who presented to the Department of Obstetrics and Gynecology, Health Research System In Vitro Fertilization (HRS IVF) Center between October 2014 and November 2015 and met the inclusion criteria were included in this study. The participants were divided into three socioeconomic groups using Kuppuswamy's socioeconomic status scale. Thirty-one participants were assigned to the low socioeconomic status group, 37 to the middle socioeconomic status group, and 33 to the high socioeconomic status group. On days 3-6 of the menstrual cycle, 10 mL of blood was collected from the participants for follicle stimulating hormone and anti-Mullerian hormone measurements. Transvaginal ultrasonography was performed for both ovaries for the purpose of counting antral follicles measuring 2-10 mm in diameter. RESULTS Both ovarian reserve parameters, namely anti-Mullerian hormone level and antral follicle count, exhibited a significant association with socioeconomic status (p=0.000 and p=0.000, respectively). The association between follicle stimulating hormone level and socioeconomic status was also significant (p=0.000). CONCLUSIONS A low socioeconomic status aggravated by sources of stress such as undernutrition and financial hardships affects ovarian reserve, which should be remembered in approaching infertile patients.

RESUMO

Infertility is common in the United States, with up to 15% of heterosexual couples experiencing difficulty in achieving conception. Family physicians often are the first physicians to evaluate couples attempting to conceive. Evaluation begins with assessment of ovulation, evaluation of anatomic abnormalities, and semen analysis. Many etiologies of anovulation can be managed by family physicians, and clinicians can offer counseling on timing of intercourse and assist patients with lifestyle changes to promote fertility. Ovulation induction for women with polycystic ovary syndrome and treatment of hypothyroidism also can be managed in the family physician's office. For couples who are referred to a reproductive endocrinology subspecialist, clinicians can provide emotional support, screen for depression and anxiety, and provide education about procedures and behaviors that can affect success rates.

RESUMO

ABSTRACT Purpose: Polycystic ovary syndrome (PCOS) is an endocrine disease characterized by chronic anovulation and hyperandrogenism. Hormonal changes can affect tear function. This study evaluates tear function and impact of hyperandrogenism on it in PCOS patients. Methods: Fifty patients with PCOS and thirty control volunteers were examined for tear break-up time, Schirmer-I and tear osmolarity. Also, serum levels of total testosterone, FSH, LH and AMH were determined in venous blood samples in the early follicular phase. PCOS patients were divided into two groups by plasma total testosterone level: Group A with normal (≤0.513 ng/ml;n=27), Group B with higher hormone level (>0.513 ng/ml;n=23). Healthy control group indicated as Group C (n=30). Results: LH, total testosterone levels were higher in the PCOS group than in the control group (p=0.012; p=0.025). Mean values of tear break-up time and Schirmer-I were different between groups and especially Group A and C were near to each other differing from B (p>0.05). Tear osmolarity results were higher in Group B, compared to A and C (p=0.049; p=0.033). No significant difference detected in tear osmolarity value means of Group A and C (p=0.107). AMH levels were higher in Group B, compared to A and C (p=0.002; p=0.001). AMH levels in Group A were higher than that of C (p=0.002). Positive correlation between levels of total testosterone and AMH was detected in all PCOS patients (n=50;Pearson's r=0.579; p<0.001). Conclusion: Tear function can be affected in PCOS patients with hyperandrogenism. Tear osmolarity is the most sensitive and objective assessment method for ocular surface changes in PCOS.


RESUMO Objetivo: A síndrome do ovário policístico (SOP) é uma doença endócrina caracterizada por anovulação crônica e hiperandrogenismo. As alterações hormonais podem afetar a função cardíaca. Este estudo avalia a função lacrimal e o impacto do hiperandrogenismo sobre ela em pacientes com SOP. Métodos: Cinquenta pacientes com SOP e trinta voluntárias de controle foram examinadas para tempo de ruptura lacrimal, Schirmer-I e osmolaridade lacrimal. Além disso, os níveis séricos de testosterona total, FSH, LH e HAM foram determinados em amostras de sangue venoso na fase folicular precoce.As pacientes com SOP foram divididas em dois grupos por nível de testosterona plasmática total: Grupo A com nível normal (≤0.513 ng/ml; n = 27), Grupo B com nível superior de hormônio (> 0,513 ng/ml; n = 23). Grupo de controle saudável indicado como Grupo C (n = 30). Resultados: Os níveis de LH e testosterona total foram maiores no grupo com SOP do que no grupo controle (p = 0,012; p = 0,025). Os valores médios de tempo de ruptura lacrimal e Schirmer-I foram diferentes entre os grupos, e especialmente os Grupos A e C estavam próximos um do outro, diferente do B (p > 0,05). Os resultados de osmolaridade lacrimal foram maiores no Grupo B, em comparação com A e C (p = 0,049; p = 0,033). Não houve diferença significativa detectada em valor médio de osmolaridade lacrimal nos Grupos A e C (p = 0,107). Os níveis de HAM foram maiores no Grupo B, em comparação com A e C (p = 0,002; p = 0,001). Os níveis de AMH no Grupo A foram superiores aos de C (p = 0,002). Uma correlação positiva entre os níveis de testosterona total e AMH foi detectada em todas as pacientes com SOP (n = 50; Pearson's r = 0,579; p < 0,001). Conclusão: a função lacrimal pode ser afetada em pacientes com SOP com hiperandrogenismo. A osmolaridade lacrimal é o método de avaliação mais sensível e objetivo para alterações da superfície ocular em SOP.

RESUMO

Methods to determine individualized breast cancer risk lack sufficient sensitivity to select women most likely to benefit from preventive strategies. Alterations in DNA methylation occur early in breast cancer. We hypothesized that cancer-specific methylation markers could enhance breast cancer risk assessment. We evaluated 380 women without a history of breast cancer. We determined their menopausal status or menstrual cycle phase, risk of developing breast cancer (Gail model), and breast density and obtained random fine-needle aspiration (rFNA) samples for assessment of cytopathology and cumulative methylation index (CMI). Eight methylated gene markers were identified through whole-genome methylation analysis and included novel and previously established breast cancer detection genes. We performed correlative and multivariate linear regression analyses to evaluate DNA methylation of a gene panel as a function of clinical factors associated with breast cancer risk. CMI and individual gene methylation were independent of age, menopausal status or menstrual phase, lifetime Gail risk score, and breast density. CMI and individual gene methylation for the eight genes increased significantly (P < 0.001) with increasing cytological atypia. The findings were verified with multivariate analyses correcting for age, log (Gail), log (percent density), rFNA cell number, and body mass index. Our results demonstrate a significant association between cytological atypia and high CMI, which does not vary with menstrual phase or menopause and is independent of Gail risk and mammographic density. Thus, CMI is an excellent candidate breast cancer risk biomarker, warranting larger prospective studies to establish its utility for cancer risk assessment.

RESUMO

BACKGROUND: Innervation of the hypothalamus and median eminence arise from the dorsal and medial raphe nuclei (DRN and MRN, respectively). The hypothalamus regulates the secretion of gonadotropins, which in turn regulate the reproductive function of males and females. However, it is not known the role of raphe nuclei in male reproductive function. Our goal was to investigate the role of the DRN and MRN in the regulation of the testicular function and secretion of gonadotropins in prepubertal rats. METHODS: Dihydroxytryptamine (5,6-DHT) in ascorbic acid was used to chemically lesion the DRN or MRN. Rats were treated at 30 days-of-age and sacrificed at 45 or 65 days-of-age. Sham-treated controls were injected with ascorbic acid only. Negative controls were untreated rats. The damage induced by the 5,6-DHT was monitored in coronal serial sections of DRN and MRN; only the animals in which lesion of the DRN or MRN was detected were included in this study. As output parameters, we measured the concentrations of noradrenaline (NA), dopamine (DA) and serotonin (5-HT) in the anterior (AH) and medial (MH) hypothalamus by high performance liquid chromatography (HPLC); whereas, circulating concentrations of gonadotropins and sexual steroids were measured by radioimmunoassay. Seminiferous epithelium and sperm quality were also evaluated. RESULTS: Lesion of DRN or MRN does not induced changes in concentrations of LH, progesterone, and testosterone. Compared with the control group, the sham or lesion of the DRN or MRN did not modify noradrenaline or dopamine concentrations in the AH and MH at 45 or 65 days of age. Meanwhile, serotonin concentrations decreased significantly in lesioned rats. Lesion of DRN induced significantly lower concentrations of FSH regardless of age; similar lesion in the MRN had no impact on FSH levels. Sperm concentration and motility were significantly decreased in the same animals. The lesion of the MRN does not induced changes in the seminiferous epithelium or gonadotropin levels. Our results suggest that raphe nuclei regulate differentially the male reproductive functions. CONCLUSIONS: The DRN but not the MRN regulates the secretion of gonadotropins and testicular function.

RESUMO

STUDY OBJECTIVE: To evaluate the effects of laparoscopic cystectomy of endometrioma and nonendometrioma ovarian cyst on ovarian reserve. DESIGN: Prospective follow-up study of patients after laparoscopic ovarian cystectomy (Canadian Task Force II-2). SETTING: Academic hospital. PATIENTS: Seventy patients underwent laparoscopic ovarian cystectomy, with bilateral endometrioma (n = 21), unilateral endometrioma (n = 29), and unilateral other benign ovarian cyst (n = 20) from February 2011 and May 2012. The control group (n = 20) comprised patients treated with laparoscopic myomectomy or laparoscopic hydrotubation and fimbrioplasty at the same time period. INTERVENTIONS: All laparoscopic operations were applied by suture homeostasis. Ovarian reserve was assessed by serum levels of anti-Müllerian hormone (AMH) and follicle-stimulating hormone (FSH) and by antral follicle count (AFC), ovarian volume, ovarian stromal pulsatility index, and resistance index on the third day of menstruation preoperatively and in postoperative months 1.6 and 12. MEASUREMENTS AND MAIN RESULTS: FSH levels increased significantly but the AMH and AFC levels declined significantly in the bilateral endometrioma group at 1 month postoperatively compared with preoperative levels (p < .05) but did not differ significantly at 6 and 12 months postoperatively. The ovarian stromal pulsatility and resistance indices in the ipsilateral ovaries decreased significantly in all patients with unilateral ovarian cysts at 6 and 12 months postoperatively compared with preoperative levels (p < .05), although the mean ipsilateral ovarian volume was significant smaller than the unaffected side. CONCLUSION: There was no detectable difference on ovarian reserve marker levels between 4 groups and from baseline values at 6 and 12 months after laparoscopic ovarian cystectomy of endometrioma, although these levels significantly declined in the first month postoperatively.
