Refractory Temporal Lobe Epilepsy in Patients with Mosaic Turner Syndrome

Turner syndrome (TS) is one of the most common sex chromosome abnormalities in women, but there are only a few case reports of patients with TS who have epilepsy or seizures. Here, we report two additional cases with drug-resistant temporal lobe epilepsy (TLE) and TS mosaicism. Patient #1 is a 22-year-old female with drug-resistant TLE whose karyotype analysis showed that 84% of interphase cells had (45,X) genotype and brain magnetic resonance imaging (MRI) initially reported as normal showed developmental left temporal lobe encephalocele. She underwent left temporal lobectomy, and she is seizure free for 10-year postoperative follow-up period. Patient #2 is a 49-year-old female who has TLE with normal brain MRI. The karyotype analysis showed that 2/30 of metaphase cells had (45, X) genotype. In addition, 11 cases of epilepsy associated with TS were determined through PubMed. The clinical characteristics of all are reviewed.

Endometrial function in women with polycystic ovary syndrome: a comprehensive review.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. An endometrial component has been suggested to contribute to subfertility and poor reproductive outcomes in affected women. The aim of this review was to determine whether there is sufficient evidence to support that endometrial function is altered in women with PCOS, whether clinical features of PCOS affect the endometrium, and whether there are evidence-based interventions to improve endometrial dysfunction in PCOS women. An extensive literature search was performed from 1970 up to July 2020 using PubMed and Web of Science without language restriction. The search included all titles and abstracts assessing a relationship between PCOS and endometrial function, the role played by clinical and biochemical/hormonal factors related to PCOS and endometrial function, and the potential interventions aimed to improve endometrial function in women with PCOS. All published papers were included if considered relevant. Studies having a specific topic/hypothesis regarding endometrial cancer/hyperplasia in women with PCOS were excluded from the analysis. Experimental and clinical data suggest that the endometrium differs in women with PCOS when compared to healthy controls. Clinical characteristics related to the syndrome, alone and/or in combination, may contribute to dysregulation of endometrial expression of sex hormone receptors and co-receptors, increase endometrial insulin-resistance with impaired glucose transport and utilization, and result in chronic low-grade inflammation, immune dysfunction, altered uterine vascularity, abnormal endometrial gene expression and cellular abnormalities in women with PCOS. Among several interventions to improve endometrial function in women with PCOS, to date, only lifestyle modification, metformin and bariatric surgery have the highest scientific evidence for clinical benefit. Endometrial dysfunction and abnormal trophoblast invasion and placentation in PCOS women can predispose to miscarriage and pregnancy complications. Thus, patients and their health care providers should advise about these risks. Although currently no intervention can be universally recommended to reverse endometrial dysfunction in PCOS women, lifestyle modifications and metformin may improve underlying endometrial dysfunction and pregnancy outcomes in obese and/or insulin resistant patients. Bariatric surgery has shown its efficacy in severely obese PCOS patients, but a careful evaluation of the benefit/risk ratio is warranted. Large scale randomized controlled clinical trials should address these possibilities.

Placental proteome abnormalities in women with gestational diabetes and large-for-gestational-age newborns

IntroductionGestational diabetes mellitus (GDM) is the most frequent metabolic complication during pregnancy and is associated with development of short-term and long-term complications for newborns, with large-for-gestational-age (LGA) being particularly common....

Undiagnosed endometrial abnormalities in women with normal hysterosalpingography scheduled for IVF

Objectives: To compare the diagnostic accuracy of three-dimensional transvaginal ultrasound (3D-US) to office hysteroscopy (OH) in the screening of uterine cavity with normal hysterosalpingography (HSG) findings for subtle endometrial abnormalities before in vitro-fertilization (IVF). Methods: A prospective cohort cost-modeling study was carried out in a University hospital. We included 120 infertile women with a normal uterine cavity on HSG scheduled for IVF. All cases were evaluated by 3D-US, and the results were compared with OH findings. Results: OH revealed cavitary endometrial lesions (CLs) in thirty-four women (28.3%). Endometrial polyps were the most common detected lesions (16, 47.1%). 3D-US had 88.2% sensitivity, 96.5% specificity, 90.9% positive predictive value, 95.4% negative predictive value, and 94.2% overall accuracy for CLs. The overall agreement between 3D-US and OH was near-perfect (κ=0.86, 95% CI=0.75-0.96). Irregular menstrual bleeds and prior endometrial procedures were significant predictors for CLs (aOR=24.96, 95% CI=2.71–230.04, P=0.005, aOR=9.16, 95% CI=2.13–39.3, P=0.002, respectively). A selective screening strategy discerning OH to women with these predictors and/or women with abnormal 2D-US would have an NPV of 92.8 % with substantial cost benefits. Conclusions: In the pre-IVF work up, 3D-US, a non-invasive imaging modality, seems to be nearly comparable to OH. Office hysteroscopy screening prioritizing women with abnormal 2D-US, irregular menstrual periods and/or prior endometrial traumatization could yield a satisfactory cost-effective approach for identifying endometrial lesions.

Salivary Alpha-Amylase Activity in Relation to Cardiometabolic Status in Japanese Adults without History of Cardiovascular Disease.

Aims: Stress is known to be a potential contributor to the development of diabetes and hypertension. However, the biological mechanisms underlying the association between cardiometabolic risk markers and the biological stress response have not yet been determined. Therefore, we examined salivary alpha-amylase and heart rate variability in relation to cardiometabolic status in a sample of healthy Japanese men and women. Methods: Participants (473 men and 1,029 women aged 30-84) underwent a 75 g oral glucose tolerance test after a 10-hr fast. The homeostasis model assessment index for insulin resistance was based on fasting and 2-hr postload glucose and insulin concentrations. Sitting blood pressure was measured twice after rest. A saliva sample was collected in the morning and salivary alpha-amylase was assayed. A 5-min heart rate variability recording was evaluated using time-domain indices of standard deviations of normal-to-normal intervals and root mean square of successive differences. Multivariate linear regression models were used to estimate associations between salivary alpha-amylase and each outcome measure. Results: Salivary alpha-amylase was associated with fasting glucose (β=0.008; 95% CI=0.002, 0.014), 2-hr postload glucose (β=0.023; 95% CI=0.004, 0.041), homeostasis model assessment index for insulin resistance (β=0.032; 95%CI=0.000, 0.064), systolic (β=1.603; 95% CI=0.479, 2.726) and diastolic (β=0.906; 95% CI=0.212, 1.600) blood pressures among women. These associations remained significant after further adjustment for heart rate variability measures. Conclusions: The elevation of salivary alpha-amylase may reflect a dysfunction of the sympathetic nervous system associated with cardiometabolic abnormalities in women.

Turner syndrome through the lens of a gynaecologist.

Turner syndrome is a rare condition affecting 1 in 2500 female births and yet is the most common sex chromosome abnormality in women. Described as a cradle-to-grave condition, it requires life-long multidisciplinary management. Accelerated atresia of the primordial follicular pool leads to premature ovarian insufficiency, which is an almost inevitable feature of Turner syndrome, especially in 45XO karyotype. Many patients will have had their diagnosis made in childhood and require paediatric endocrinology management especially for induction of puberty. At the age of 18, patients may then be transitioned to an adult service. Continuation of multidisciplinary care for these women requires input from specialist services in menopause care, reproductive medicine and high-risk pregnancy, cardiology, endocrinology, bone health and psychosocial care. A gynaecologist may take on the mantle of lead clinician especially during the perceived reproductive years of a Turner syndrome patient's life, hinging together management input from other disciplines. This review attempts to summarise an overview of the involvement of such a multidisciplinary team in the management of a single but complex condition, through the lens of a gynaecologist.

Increased Risk of Aortic Dissection Associated With Pregnancy in Women With Turner Syndrome: A Systematic Review.

Turner syndrome (TS) is one of the most common chromosomal abnormalities in women. The condition is characterized by gonadal dysgenesis and is associated with structural cardiac abnormalities. Assisted reproductive technology with oocyte donation may be successful but places women with TS at increased risk of aortic dissection and death. To summarize all cases of aortic dissection associated with pregnancy in women with TS and provide guidance regarding the safety of pregnancy. Systematic review of PubMed for reports of women with TS, aortic dissection, and pregnancy. There are 14 total reported cases of aortic dissection associated with pregnancy in women with TS. Ten of these cases occurred during pregnancy or in the first month postpartum. The majority of affected pregnancies resulted from oocyte donation, 2 of which were multiple gestations. Two women had a documented history of hypertension, and 3 pregnancies were complicated by preeclampsia. Bicuspid aortic valve and coarctation of the aorta were the most common associated cardiac anomalies. More than half of women had some degree of aortic dilatation. Two women had no identifiable risk factors. Women with TS who desire pregnancy must be thoroughly counseled regarding the increased risk of aortic dissection during pregnancy and postpartum. Preconception consultation with maternal-fetal medicine, reproductive endocrinology, and cardiology is necessary along with a comprehensive physical evaluation. If women with TS choose to pursue pregnancy, they require rigorous cardiac monitoring each trimester during pregnancy and postpartum.

Neoplasia in Turner syndrome: a retrospective cohort study in a tertiary referral centre in Belgium

ABSTRACT Objectives Patients with Turner syndrome (TS), the most common sex chromosome abnormality in women, can suffer from a variety of well-researched reproductive, cardiovascular, metabolic, and autoimmune comorbidities. Few studies investigate the neoplasia risk. We assessed the general neoplasia risk in TS women, and more specifically, the gonadoblastoma/dysgerminoma risk in the subgroup with Y chromosome mosaicism, and evaluated potential risk factors for neoplasia development, such as karyotype, metabolic and autoimmune comorbidity, and treatment with growth hormone and/or estrogen replacement. Design 10-year retrospective cohort study in a tertiary referral centre in Belgium. Results 105 TS women were included (median age 29; range 2–69). Six malignant tumours were detected in 5 (4.8%) patients (SIR = 0.6, 95% CI 0.2–1.0). In addition, 2 benign meningiomas were observed, resulting in 3 (2.9%) tumours of the central nervous system (CNS; SIR = 19.9, 95% CI 4.0–35.8). No breast cancer was noted. Benign neoplasms occurred in 22 women (21.0%), with skin lesions being the most frequent. All patients with Y chromosome mosaicism (n = 9; 8.6%) underwent prophylactic gonadectomy, but gonadoblastoma/dysgerminoma was not detected. A weak association was found between any tumour type and autoimmune comorbidity (r = 0.24; p = 0.02). Conclusion The overall malignancy risk was not increased, but a different pattern of occurrence is apparent, with an increased risk of CNS and skin tumours and a decreased breast cancer risk. Gonadoblastoma/dysgerminoma was not reported. There is a need for centralised multidisciplinary care and prospective research to unravel and predict the neoplasia risk.

HIV and development of epithelial cell abnormalities in women with prior normal cervical cytology in Nigeria

BackgroundHIV-associated cellular immune dysfunction has been linked to higher risk of cervical dysplasia and cancer in HIV infected women. We sought to understand the relationship between HIV and development of epithelial cell abnormalities (ECA) at follow-up in women with prior normal cervical cytology (NCC).MethodsRetrospective cohort analysis of women who received a Pap test at the Operation Stop Cervical Cancer Unit in Jos, Nigeria over a 10-year period (2006–2016). We analyzed the data of women with NCC at first Pap who had at least one follow-up cytology result for time-to-detection of ECA. We determined follow-up time in years from date of first NCC to date of first ECA report or date of last NCC follow up report with censoring at last follow-up date or December 31st, 2016 whichever came first. The primary outcome was development of any ECA as defined by the Bethesda 2001 reporting system. We identified demographic and clinical factors associated with incident ECA using multivariable Cox regression.ResultsA total of 1599 women were eligible for this analysis. Overall, 3.7% (57/1556) of women reported being HIV infected. The median age at first Pap was 39 years (IQR; 33–45). The HIV infected women were younger (36.3 ± 8.1) compared to those uninfected (39.3 ± 6.6), p = 0.005. After an accrued follow-up time of 3809 person-years (PYs), 243 women (15%) had an ECA with an event rate of 6.38 per 100 PYs. Women ≥35 years at first Pap were more likely to have an ECA compared to those < 35 years (7.5 per 100 PYs vs 3.8 per 100 PYs, HR = 1.96; 95% CI: 1.4, 2.8). HIV status was not significantly associated with developing ECA in either unadjusted (7.4 per 100 PYs vs 6.4 per 100 PYs, HR = 1.17; 95% CI: 0.53, 2.3) or adjusted analyses (aHR = 1.78; 95% CI: 0.87, 3.65).ConclusionWomen living with HIV and on successful antiretroviral treatment may not have a differential hazard in the development of ECA during follow up after a prior normal Pap. Offering a repeat CCS to women who are 35 years or older irrespective of HIV status is likely an effective strategy in resource limited settings.

Parallel derivation of X-monosomy induced pluripotent stem cells (iPSCs) with isogenic control iPSCs.

Turner syndrome, caused by partial or complete loss of one copy of X-chromosome (45,X), is the most common sex chromosome abnormality in women with an incidence of 1 in 2500 female births. Here, we report the generation and characterization of induced pluripotent stem cells (iPSCs) carrying X-monosomy anomaly, with isogenic control iPSCs. Among the iPSC lines generated from 46XX-fibroblasts, one spontaneously lost a copy of X-chromosome following the reprogramming process, establishing the 45X-iPSC line.

A comparison of screening tests for detection of high-grade cervical abnormalities in women living with HIV from Cameroon

BackgroundWomen living with human immunodeficiency virus (WLWH), especially those living in low- and middle-income countries (LMIC), are at increased risk of cervical cancer. The optimal cervical-cancer screening strategy for WLWH has not been determined. We therefore conducted a pilot study of screening methods in WLWH living in Limbe, Cameroon.MethodsFive-hundred sixty-six WLWH, aged 25–59 years, were enrolled. After self-collecting a cervicovaginal specimen, they underwent a pelvic exam, during which a provider also collected a cervical specimen and visual inspection after acetic acid (VIA) was performed. Both self- and provider-collected specimens were tested for high-risk HPV by the Xpert HPV Test (Cepheid, Sunnyvale, CA, USA), with the residual of the latter used for liquid-based cytology. Women testing HPV positive on either specimen and/or VIA positive were referred to colposcopy and biopsies. However, because of poor attendence for follow-up colposcopy for the screen positives due to civil strife and technical issues with biopsies, high-grade cytology and/or clinical diagnosis of cancer was used as the primary high-grade cervical abnormality endpoint. Clinical performances for high-grade cervical abnormality of HPV testing and VIA for screening WLWH, and the most carcinogenic HPV genotypes and/or VIA to triage high-risk HPV-positive WLWH, were evaluated.ResultsFour-hundred eighty-seven (86.0%) WLWH had results for HPV testing on both specimen, VIA, and cytology and were included in the analysis. Forty-nine (10.1%) had a high-grade cervical abnormality. HPV testing on provider- and self-collected specimens was more sensitive than VIA (95.9 and 91.8% vs. 43.8%, respectively, p < 0.01 for both comparisons) for identifying women with high-grade cervical abnormalities. HPV testing on provider- and self-collected specimens was less specific than VIA (57.5 and 51.6% vs. 89.7%, respectively, p < 0.01 for both comparisons) for identifying women with high-grade cervical abnormalities; HPV testing on provider-collected specimens was more specific than on self-collected specimens (p < 0.01). Among HPV-positive women, HPV16/18/45 detection or VIA positivity had a sensitivity and positive predictive value of 73.5 and 29.0%, respectively, for provider-collected specimens and 68.8 and 22.9%, respectively, for self-collected specimens for high-grade cervical abnormalities.ConclusionsHPV testing was more sensitive but less specific than VIA for detection of high-grade cervical abnormality in WLWH. Improved triage methods for HPV-positive WLWH are needed.Trial registrationNCT04401670 (clinicaltrials.gov); retrospectively registered on May 26, 2020

Hypothalamic-Pituitary-Adrenal Axis Responses in Women with Endometriosis-Related Chronic Pelvic Pain.

Some chronic pain conditions and comorbidities suppress the hypothalamic-pituitary-adrenal (HPA) axis and response to dynamic testing. We measured HPA axis responses to corticotropin-releasing hormone (CRH) administration in relation to chronic pelvic pain and endometriosis. In a cross-sectional study of women (n = 54) with endometriosis-associated chronic pelvic pain (n = 22), chronic pelvic pain alone (n = 12), or healthy volunteers (n = 20), adrenocorticotropic-releasing hormone (ACTH) and cortisol levels were measured at 0, 15, 30, and 45min after intravenous ovine CRH administration. ACTH and cortisol delta (peak-baseline) and area under the curve (AUC) were compared by study group and assessed for association with race and menstrual and non-menstrual pain severity. HPA axis responses did not differ among the racially diverse groups or in those with pain compared with healthy volunteers. However, when stratified by race, ACTH delta (129.9 ± 130.7 vs. 52.5 ± 66.0pg/mL; p = 0.003), ACTH AUC (4813 ± 4707 vs. 2290 ± 2900min*pg/mL; p = 0.013), and cortisol delta (26.3 ± 21.5 vs. 13.2 ± 9.7μg/mL; p = 0.005) were significantly higher in black (n = 10) than predominately white (non-black) subjects (n = 44; 39/44 white). In analyses among primarily white (non-black) women, greater menstrual pain severity was associated with blunted ACTH delta (p = 0.015) and cortisol delta (p = 0.023), and greater non-menstrual pain severity with blunted cortisol delta (p = 0.017). Neuroendocrine abnormalities in women with chronic pelvic pain may differ by pain manifestations and may vary by race. The higher HPA axis response in black women merits investigation in pelvic pain studies stratified by race. In white (non-black) women experiencing pain, a blunted response was related to pain severity suggesting pain affects women independently of endometriosis lesions.

Investigating resting brain perfusion abnormalities and disease target-engagement by intranasal oxytocin in women with bulimia nervosa and binge-eating disorder and healthy controls

Advances in the treatment of bulimia nervosa and binge-eating disorder (BN/BED) have been marred by our limited understanding of the underpinning neurobiology. Here we measured regional cerebral blood flow (rCBF) to map resting perfusion abnormalities in women with BN/BED compared with healthy controls and investigate whether intranasal oxytocin (OT), proposed as a potential treatment, can restore perfusion in disorder-related brain circuits. Twenty-four women with BN/BED and 23 healthy women participated in a randomized, double-blind, crossover, placebo-controlled study. We used arterial spin labelling MRI to measure rCBF and the effects of an acute dose of intranasal OT (40 IU) or placebo over 18–26 min post dosing, as we have previously shown robust OT-induced changes in resting rCBF in men in a similar time-window (15–36 min post dosing). We tested for effects of treatment, diagnosis and their interaction on extracted rCBF values in anatomical regions-of-interest previously implicated in BN/BED by other neuroimaging modalities, and conducted exploratory whole-brain analyses to investigate previously unidentified brain regions. We demonstrated that women with BN/BED presented increased resting rCBF in the medial prefrontal and orbitofrontal cortices, anterior cingulate gyrus, posterior insula and middle/inferior temporal gyri bilaterally. Hyperperfusion in these areas specifically correlated with eating symptoms severity in patients. Our data did not support a normalizing effect of intranasal OT on perfusion abnormalities in these patients, at least for the specific dose (40 IU) and post-dosing interval (18–26 min) examined. Our findings enhance our understanding of resting brain abnormalities in BN/BED and identify resting rCBF as a non-invasive potential biomarker for disease-related changes and treatment monitoring. They also highlight the need for a comprehensive investigation of intranasal OT pharmacodynamics in women before we can fully ascertain its therapeutic value in disorders affecting predominantly this gender, such as BN/BED.

Frequency of menstrual abnormalities and their associated neuroimaging findings in women with focal refractory epilepsy.

Patients with refractory epilepsy can suffer from psychological and physical problems. Epilepsy can also be associated with menstruation abnormalities in women. In this paper, we aim to survey women with focal refractory epilepsy who also suffer from menstrual abnormalities. This cross-sectional study was performed in 2018 in Tertiary Epilepsy Center in Kashani Hospital, Isfahan, Iran and Milad hospital, Isfahan, Iran. A total number of 381 patients diagnosed with refractory epilepsy joined the study based on an inclusion and exclusion criteria. Clinical characteristics of epilepsy, menstrual issues and brain MRI findings were assessed. Among 381 women with refractory epilepsy, 250 had refractory focal epilepsy (65.61%), and the others (34.39%) had generalized refractory epilepsy. 132 patients out of 381 had menstrual abnormalities (34.65%). Among 132 women with coexisting refractory epilepsy and menstrual abnormalities, 86 (65.15%) were diagnosed with refractory focal epilepsy, and 46 (34.86%) had generalized refractory epilepsy (p value = 0.041). Oligomenorrhea-hypomenorrhea was the most common type of menstrual abnormality in women with refractory epilepsy seen in 83 (62.87%) (p value = 0.039). The most common brain MRI pathology in women with refractory focal epilepsy was mesial temporal sclerosis (MTS) (39.20%, p = 0.00). We report that almost one-third of women with refractory epilepsy suffer from menstrual disorders, and the most common disorder was Oligomenorrhea-hypomenorrhea, and the most common brain pathology was MTS. It has also been a hypothesis that reproductive dysfunctions are connected to temporal lobe malfunctions, and more specific studies are required in this issue.

Abstract A17: Human papillomavirus type 16 and 18 viral loads as predictors associated with abnormal cervical cytology among women in Saudi Arabia

Abstract The present study aimed to screen for and genotype HPV among Saudi women; develop sensitive quantitative polymerase chain reaction (qPCR) assays to detect the viral load for the two most common HPV types, namely 16 and 18; and assess whether HPV viral load could be used as a marker for cervical abnormality and disease progression. This study examined 733 specimens (both formalin-fixed, paraffin-embedded specimens and PAP smear samples) from women who underwent cervical screening. The specimens and samples were processed for DNA extraction and then tested for HPV DNA. Approximately 165 specimens (18%) were positive for HPV. Those specimens were genotyped using a reverse line blotting hybridization assay. The results indicated that the most common HPV types detected were a single infection with HPV 16 (51%) or with HPV 18 (28%) followed by infections with multiple HPV types (~7%). A qPCR TaqMan assay developed in-house was used to determine the viral load for HPV genotypes 16 (n=80) and 18 (n=45). Viral loads for both HPV types were significantly associated with cervical cytology grade (P &amp;lt; 0.05). The odds ratio (OR) for the HPV 16 viral load was high for specimens with cervical cancer (OR, 18.8; 95% CI, 4.3–82.9) or for those with high-grade squamous intraepithelial lesions (OR, 14.7; 95% Cl, 2.43–88.49). For the HPV 18 viral load, the OR was significant only for specimens with cervical cancer (OR, 11.1; 95% Cl, 2.2–54.9). Logistic regression models for HPV 16 and for HPV 18 viral load levels were significant, with higher viral load associated with cervical abnormalities. These findings indicate that viral load is a predictor significantly associated with cytology abnormality in women who are positive for high-risk HPVs and suggest integrating a viral load test into current clinical screening practices for HPV-positive women.

Metabolic Effects of Whey Protein Isolate Supplementation on Cholesterol and Triglycerides in Women with Polycystic Ovary Syndrome

The current study examined the acute‐ and chronic effects of whey protein isolate ingestion on plasma cholesterol and triglyceride concentrations in women with polycystic ovary syndrome (PCOS). PCOS, an endocrine abnormality in women of reproductive age, is characterized by menstrual cycle disturbance, hyperandrogenism and obesity. Women with PCOS have altered metabolic profiles and are more likely to develop type 2 diabetes and/or liver disorders such as non‐alcoholic fatty liver disease (NAFLD). Nutritional management options are severely limited. Whey protein isolate (WPI) improves metabolic parameters in patients with and without type 2 diabetes, but its therapeutic potential in polycystic women has yet to be realized. Given the association between PCOS and NAFLD, we hypothesized that supplementation with WPI may attenuate circulating cholesterol and triglycerides in a polycystic population. Fifteen premenopausal women with PCOS and eleven healthy, regularly menstruating women underwent three 150‐min oral glucose tolerance tests (OGTT): (i) OGTT without protein preload, (ii) OGTT on 1st, and (iii) 40th day of protein preload. Participants consumed 35g protein daily with protein intake 30 min before carbohydrate load on test days. Plasma levels of cholesterol and triglycerides were assessed at baseline, day 1 and day 40 to determine acute and chronic effects on cholesterol and triglycerides using a Biolis 24i chemistry analyzer. (Participant recruitment, data collection and analyses in progress.) Protocols used in this study were approved by the TWU Institutional Review Board. Mixed Model Repeated Measure ANOVA indicates that time and condition (PCOS vs control) did not have a significant effect on cholesterol or triglyceride levels within and between groups (p &gt; .05). However, preliminary data indicate that disease condition had a significant impact on cholesterol (p&lt; .001) and triglyceride (p = .001) concentrations at baseline. Changes in cholesterol and triglyceride levels after 40 days of protein preload are currently being analyzed. Women with PCOS have higher levels of cholesterol and triglycreides than those without this condition. While acute effects of 35g WPI ingestion do not seem to alter these levels, a longer duration of supplementation may induce more beneficial effects (currently being conducted). Findings from this study will provide foundational support for WPI as a nutritional treatment for PCOS and reveal insights into cholesterol metabolism mechanisms that are affected by PCOS and NAFLD.Support or Funding InformationGlanbia Nutritionals, INC; Human Nutrition Research Funds, Texas Woman’s University; Research Enhancement Program, Texas Woman’s University

The Role of medicinal herbs in treatment of insulin resistance in patients with Polycystic Ovary Syndrome: A literature review.

Background Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine abnormalities in women. Due to the side effects of drugs, the tendency to use natural antioxidants and anti-inflammatory agents to regulate metabolism, hyperinsulinemia, and hyperlipidemia in PCOS patients has been increased. This review aimed to investigate the role of herbal substances on the treatment of PCOS. Methods The present review was carried out using keywords such as polycystic ovary syndrome and/or PCOS and/or herb. Databases including Web of Science, PubMed, and Science Direct were used to collect all related articles published from 1990 to 2019. We excluded studies unrelated to the PCOS and medical herbs. Results Overall, 361 records were identified through database searching. After primary screening and the full-texts assessment, 323 records were excluded, and 38 articles were finally included. The results indicate that some medicinal herbs may have a key role in treating PCOS. The compounds in these medical herbs can affect lipid profiles (Aloe vera, chamomile, and cinnamon), insulin resistance (cinnamon, chamomile, Aloe vera, and Camellia sinensis), blood glucose (Aloe vera, cinnamon, and Camellia sinensis), hormones (Aloe vera, silymarin, chamomile, fenugreek, Camellia sinensis, Heracleum persicum, Potentilla, Mentha spicata, Foeniculum vulgar, licorice, and Marrubium), and ovarian tissue (Aloe vera, chamomile, Camellia sinensis, Mentha spicata, and silymarin). Conclusion Natural substances such as Aloe vera, cinnamon, green tea, fenugreek, and silymarin can be used as a new supportive care for PCOS. Further clinical trials are warranted to confirm their benefits and safety.

Human papillomavirus type 16 and 18 viral loads as predictors associated with abnormal cervical cytology among women in Saudi Arabia

The detection of HPV viral DNA is regularly conducted with cervical screening. However, using a molecular marker such as the viral load may serve as a predictor associated with disease detection and progression. The present study aimed to screen for and genotype HPV among women in Saudi Arabia, develop and validate sensitive quantitative polymerase chain reaction (qPCR) assays to detect viral load for the two most common HPV types, namely 16 and 18, and assess whether HPV viral load could be used as a marker for cervical abnormality and disease progression. This study examined 733 specimens (both formalin-fixed paraffin embedded specimens and PAP smear samples) from women who underwent cervical screening. The specimens and samples were processed for DNA extraction and then tested for HPV DNA using nested PCR. Approximately 165 specimens (18%) were positive for HPV. Those specimens were genotyped using a reverse line blotting hybridization assay. The results indicated that the most common HPV types detected were a single infection with HPV 16 (51%) or with HPV 18 (28%) followed by infections with multiple HPV types (~7%). A qPCR TaqMan assay developed and validated in-house was used to determine viral load for HPV genotypes 16 (n = 80) and 18 (n = 45). Viral loads for both HPV types were significantly associated with cervical cytology grade (P < 0.05). The odds ratio (OR) for the HPV 16 viral load was high for specimens with cervical cancer (OR, 18.8; 95% CI, 4.3–82.9) or for those with high-grade squamous intraepithelial lesions (OR, 14.7; 95% Cl, 2.43–88.49). For the HPV 18 viral load, the OR was significant only for specimens with cervical cancer (OR, 11.1; 95% Cl, 2.2–54.9). Logistic regression models for HPV 16 and for HPV 18 viral load levels were significant, with higher viral load associated with cervical abnormalities. These findings indicate that viral load is a predictor significantly associated with cytology abnormality in women who are positive for high-risk HPVs and suggest that integrating a viral load test into current clinical screening practices for HPV-positive women is warranted in Saudi Arabia.

Contrast-enhanced spectral mammography (CESM) in women presenting with palpable breast findings

ObjectivePalpable breast abnormalities in women warrant diagnostic evaluation. Contrast-enhanced spectral mammography (CESM) is a novel technique which has demonstrated early promising results in the diagnostic imaging setting. The purpose of this study was to evaluate the role of CESM for imaging of palpable breast abnormalities and compare it to the current routine imaging work-up. Materials and methodsThis retrospective study included women with palpable breast masses who underwent diagnostic CESM and ultrasound between 2012 and 2019. Diagnostic parameters for low-energy images, CESM and targeted ultrasound were calculated and compared. Analysis was performed at the lesion level. Additional incidental findings were reported separately. ResultsIncluded in this study were 138 women with 147 palpable breast abnormalities, of which 38 were cancers. Standard 2D mammography revealed 36/38 cancers (sensitivity 94.7%). All 38 cancers (100%) were detected at CESM and at targeted ultrasound. Negative predictive value for 2D mammography was 97.8% (91/93), and 100% for both ultrasound (74/74) and for CESM (80/80). None of the palpable masses that were negative at CESM but positive at ultrasound (n = 13) were malignant. Two additional incidental cancers were detected with CESM at the contralateral breast to the palpable lump. ConclusionCESM could be useful for assessment of palpable breast abnormalities, potentially decreasing the number of unnecessary benign biopsies performed.

Dendrobium nobile Lindl. polysaccharides improve follicular development in PCOS rats

Polycystic ovary syndrome (PCOS) is the most typical and common metabolic abnormalities in women of reproductive age. This study examined the protective effects of Dendrobium nobile Lindl. polysaccharides (DNLP) on ovarian follicular development in letrozole-induced PCOS rats and explored the underlying molecular mechanisms. The PCOS rats showed the increased body weight, serum testosterone and luteinizing hormone levels and insulin resistance. DNLP treatment reduced the body weight, serum testosterone level and insulin resistance, but failed to affect luteinizing hormone level in the PCOS rats. DNLP treatment recovered disrupted estrous cycle in the PCOS rats. DNLP treatment decreased antral follicles and increased the thickness of the granular cell layer. DNLP treatment increased the PCNA mRNA and protein expression levels in the PCOS ovarian tissues, and inhibited cell apoptosis in the PCOS ovarian tissues via regulating apoptosis-related proteins including Bax, Bcl-2 and caspase-3. In summary, this study demonstrated the protective effects of DNLP on the ovaries in the letrozole-induced PCOS rat model. DNLP exerted its protective effects via improving follicular development and inhibiting apoptosis of ovarian granular cells in PCOS rats. This study will provide experimental basis for the future clinical application of DNLP in the treatment of PCOS.
