Abstract

Background: Menarche, a milestone in the reproductive life span of a woman, is influenced by several genetics and environmental factors. There is no consensus regarding the impact of body mass index (BMI) and lipid profiles on the age of menarche, as the results of various studies demonstrate. Objective: To investigate the correlation between age of menarche and BMI/lipoprotein profile in a community sample of Iranian girls.
Materials and Methods: In the study, 370 girls, aged 10-16 years, who began their menarche within six months prior to the study, were recruited from the Tehran Lipid and Glucose Study (TLGS) population. Information was documented regarding their body composition, including height, weight, BMI, waist and hip circumference were collected and their lipid profiles were assessed after a 12-hour fast.
Results: In this study, the mean±SD of age of menarche and BMI were 12.6±1.1 years and 21.7±3.9 kg/m2, respectively. There were statistically significant relationships between age of menarche and height, BMI, waist circumference, and the maternal educational level. The relationship between age of menarche and the weight and lipid profiles of subjects was not statistically significant.
Conclusion: Age at menarche is not influenced by lipid profiles but it is influenced by BMI.

Abstract

Background: Polycystic ovary syndrome (PCOS) is a complex disease having both genetic and environmental components and candidate genes on obesity and insulin metabolism have been hypothesized to be involved in its etiology.
Objective: We examined the possible association of adiponectin and insulin receptor gene polymorphisms with PCOS.
Materials and Methods: A total of 186 women with PCOS using NIH criteria and 156 healthy women were recruited. Their samples were genotyped for the polymorphism in exon 17 and 8 of the insulin receptor gene or exon and intron 2 of the adiponectin gene.
Results: The distributions of genotypes and alleles of both polymorphisms were not different in women with PCOS and controls. There was no significant differences on the anthropometric and hormonal profiles of various adiponectin and insulin receptor genes polymorphisms among both groups.
Conclusion: Adiponectin and insulin receptor gene polymorphisms are not associated with PCOS in a sample of Iranian population.

Abstract

Background: Infertility has a varied impact on multiple dimensions of health and functioning of women.
Objective: We aimed to identify the burden of infertility and its influencing factors based on a population based study conducted in four provinces of Iran.
Materials and Methods: A sample of 1126 women, aged 18-45 years, was selected using the multi stage, stratified probability sampling procedure; those met the eligibility criteria were invited for further comprehensive interview. This study used the definition of infertility proposed by World Health Organization “the woman has never conceived despite cohabitation and exposure to pregnancy for a period of 1 year”.
Results: The overall prevalence of lifetime infertility and current primary infertility were 21.1% (95% CI: 18.4- 23.8) and 6.4% (95% CI: 4.8-8) respectively. The probability of first pregnancy at the end of 2 years of marriage was 94% for all ever-married women. Infertility were observed as significantly higher among women age 31-35 (OR: 4.6; 95% CI: 1.9-11.5; p=0.001) and women with more than 9 years of education (OR: 2.8; 95% CI: 1.5-3.3; p<0.0001).
Conclusion: The necessities of modern living have compelled many women to postpone childbearing to their late reproductive years; however they must be informed of being at risk of infertility with ageing.

Abstract

Background: Recently there is a focus on the antioxidants as adjuvant treatment of polycystic ovary syndrome (PCOS), the most endocrinopathy in reproductive age women.
Objective: The aim of this review is answer to the question whether antioxidants are effective for managing of hormonal and metabolic problems in women with PCOS based on first degree evidences from Iran.
Materials and Methods: A systematic review of clinical trials was done in Persian and international databases including PubMed, Scientific Information Database, Google Scholar, Iran Medex, and Magiran up to 2013. Keywords were including polycystic ovary syndrome, Iran, vitamin, antioxidant. From 440 potential studies found electronically, 11 studies; including 444 women in intervention and 390 women in control groups. Intervention in three studies was Calcium-vitamin D or calcitriol; in three studies was ω-3 fatty acids; in two studies was N-acetyl cysteine; in one study was folic acid; in one study was Zinc; and in one study was Soy.
Results: Finally, 11 studies that were relevant and met the inclusion criteria reviewed. There were 7 studies in English and 4 studies in Persian. We couldn’t include all studies because all full texts were not accessible.
Conclusion: The results showed that antioxidants and vitamins have positive effects on management of PCOS women. Although it seems more studies is necessary in this field.

Abstract

Background: Pregnancy has a huge impact on the thyroid function in both healthy women and those that have thyroid dysfunction. The prevalence of thyroid dysfunction in pregnant women is relatively high.
Objective: The objective of this review was to increase awareness and to provide a review on adverse effect of thyroid dysfunction including hyperthyroidism, hypothyroidism and thyroid autoimmune positivity on pregnancy outcomes.
Materials and Methods: In this review, Medline, Embase and the Cochrane Library were searched with appropriate keywords for relevant English manuscript. We used a variety of studies, including randomized clinical trials, cohort (prospective and retrospective), case-control and case reports. Those studies on thyroid disorders among non-pregnant women and articles without adequate quality were excluded.
Results: Overt hyperthyroidism and hypothyroidism has several adverse effects on pregnancy outcomes. Overt hyperthyroidism was associated with miscarriage, stillbirth, preterm delivery, intrauterine growth retardation, low birth weight, preeclampsia and fetal thyroid dysfunction. Overt hypothyroidism was associated with abortion, anemia, pregnancy-induced hypertension, preeclampsia, placental abruption, postpartum hemorrhage, premature birth, low birth weight, intrauterine fetal death, increased neonatal respiratory distress and infant neuro developmental dysfunction. However the adverse effect of subclinical hypothyroidism, and thyroid antibody positivity on pregnancy outcomes was not clear. While some studies demonstrated higher chance of placental abruption, preterm birth, miscarriage, gestational hypertension, fetal distress, severe preeclampsia and neonatal distress and diabetes in pregnant women with subclinical hypothyroidism or thyroid autoimmunity; the other ones have not reported these adverse effects.
Conclusion: While the impacts of overt thyroid dysfunction on feto-maternal morbidities have been clearly identified and its long term impact on childhood development is well known, data on the early and late complications of subclinical thyroid dysfunction during pregnancy or thyroid autoimmunity are controversial. Further studies on maternal and neonatal outcomes of subclinical thyroid dysfunction maternal are needed.

Abstract

Background: Women engaged with polycystic ovarian syndrome (PCOS), as the commonest endocrine disorder, are known to have a specific type of adiposity. Birth weight is among different contributors reported to be responsible for this diversity.
Objective: We aimed to compare the relation between birth weight and body fat mass (BFM)/ body lean mass (BLM) in PCOS and their age and body mass index (BMI) matched normal controls.
Materials and Methods: In this case-control study, a total number of 70 reproductive aged women, diagnosed with PCOS and 70 age- BMI matched healthy women without hirsutism and/or ovulatory dysfunction were recruited., control group had no polycystic ovaries in ultrasonographic scans. A detailed history of birth weight was taken and was divided into the following categories: <2,500 (low birth weight, LBW) and 2,500-4,000 (normal birth weight; NBW).
Results: Results showed that LBW prevalence was higher in women with PCOS than in controls (19.3% (27) vs. 15.7% (22)). Also body fat and lean mass (BFM, BLM) have increased in adult women with PCOS who were born underweight compared to their normal (19.8±9.05 vs. 12.9±4.5, p=0.001 and 48.9±6.9 vs. 43.2±5.8, p=0.004 respectively).
Conclusion: Fetal birth weight influences on the adulthood obesity, BFM and BLM. This impact is different among women with and without PCOS.

Abstract

Abstract
Background: Polycystic ovarian syndrome is an endocrine disorder with many complications. This syndrome is a growing concern among adolescents around the world, with varying reports of its prevalence in different parts of the world.
Objective: This study aimed to determine the prevalence of polycystic ovary syndrome in adolescents by a systematic review and meta-analysis.
Materials and Methods: In this study, a search for published articles with an English language limitation and without a time limit was done in different databases (Scopus, PubMed, and Web of Science, Emabse and Cochrane) in January 2019. The 12 studies that met the criteria for entering a qualitative assessment scale of 5 and higher were subjected to systematic review and meta-analysis. Egger and Beggchr('39')s tests were used to check the publication bias. Data were analyzed with STATA software, version 11.1.
Results: Twelve studies were included for meta-analysis. The total number of participants in the study was 149,477. The average quality score of all studies was 8.67 (range: 5-10). The prevalence of polycystic ovarian syndrome in adolescents based on the Rotterdam criteria was 11.04% (95% CI: 6.84-16.09%), based on the National Institute of Health criteria, it was 3.39% (95% CI: 0.28-9.54%), and based on Androgen Excess and Polycystic Ovary Syndrome Society, it was 8.03% (95% CI: 6.24-10.01%)
Conclusion: The result of this study showed that there is a variation in the prevalence of PCOS in adolescents based on different criteria; we suggest more community-based studies among adolescences in different parts of the world.

Abstract

Background: The amniotic membrane plays an important role in maintaining a healthy pregnancy. The main population cells from amniotic membrane include human amnion epithelial cells (hAECs) which have been shown to possess immunomodulatory properties.
Objective: The proximity of hAECs with monocyte leads to the generation of tollerogenic dendritic cells.
Materials and Methods: hAECs were obtained from normal pregnancy. Peripheral blood monocytes were isolated by anti-CD14 MACS method. Co-cultures of monocytes and hAECs were established in Transwell chambers supplemented with granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) in the absence and presence of lipopolysaccharide (LPS) to produce immature and mature DCs, respectively. Immunophenotyping of the obtained DCs was done through flow cytometry and the production of cytokines was measured by ELISA. Mixed leukocyte Reaction (MLR) was also performed for the functional assessment of DCs.
Results: Immunophenotyping of [hAECs - Immature DC (iDC)] and [hAECs - iDC] + LPS cells revealed that the expression of CD1a, CD80, CD86, CD40, HLA-DR, and CD83 markers showed no significant difference as compared with the control group (iDCs and mDCs alone). In the [hAECs-iDCs] + LPS cells, the percentage of CD14 cells at the ratio of 1:2.5 showed significant differences compared to the control group. The production of IL-10 and IL-12 showed no significant difference in any of the cultures as compared to the control groups. Also, co-cultured DCs did not inhibit proliferation of lymphocyte.
Conclusion: Our findings show that factors secreted from cultured hAECs are unable to generate of tollerogenic dendritic cells. To achieve a better understanding of other mechanisms more investigations are needed.
