Lipid Profile in Patients With Primary Ovarian Insufficiency: A Systematic Review and Meta-Analysis.

Front Endocrinol (Lausanne) 2022 10;13:876775. Epub 2022 Jun 10.

Beijing Research Institute of Chinese Medicine, Beijing University of Chinese Medicine, Beijing, China.

Backgrounds: A large number of studies have investigated the effect of early menopause on cardiovascular disease (CVD) outcomes and the relationship between the levels of lipid profile and primary ovarian insufficiency (POI). However, the results are inconsistent. The aim of this meta-analysis was to assess whether the levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) changed in women with POI relative to healthy controls.

Both cis and trans-acting genetic factors drive somatic instability in female carriers of the FMR1 premutation.

Sci Rep 2022 Jun 21;12(1):10419. Epub 2022 Jun 21.

Department of Biochemistry and Molecular Medicine, University of California Davis, School of Medicine, Sacramento, CA, 95817, USA.

The fragile X mental retardation (FMR1) gene contains an expansion-prone CGG repeat within its 5' UTR. Alleles with 55-200 repeats are known as premutation (PM) alleles and confer risk for one or more of the FMR1 premutation (PM) disorders that include Fragile X-associated Tremor/Ataxia Syndrome (FXTAS), Fragile X-associated Primary Ovarian Insufficiency (FXPOI), and Fragile X-Associated Neuropsychiatric Disorders (FXAND). PM alleles expand on intergenerational transmission, with the children of PM mothers being at risk of inheriting alleles with > 200 CGG repeats (full mutation FM) alleles) and thus developing Fragile X Syndrome (FXS).

Primary ovarian insufficiency secondary to chemotherapy with inotuzumab ozogamicin and other agents.

J Assist Reprod Genet 2022 Jun 21. Epub 2022 Jun 21.

Section of Reproductive Endocrinology and Infertility, Department of Obstetrics and Gynecology, The University of Chicago, Chicago, IL, USA.

Recent advances in targeted therapy with monoclonal antibodies have significantly improved outcomes for people with cancer, sometimes allowing patients to avoid ovotoxic agents altogether. The current understanding is that monoclonal antibody cancer therapies that are not targeted to ovarian antigens should not impact ovarian reserve or increase the risk of primary ovarian insufficiency (POI). We present a case of rapid onset POI in a 23-year-old patient following chemotherapy for relapse/refractory B-cell acute lymphoblastic leukemia with a monoclonal antibody drug-conjugate, inotuzumab ozogamicin, that targets CD22.

Autism spectrum disorder in the fragile X premutation state: possible mechanisms and implications.

J Neurol 2022 Jun 20. Epub 2022 Jun 20.

Medical Investigation of Neurodevelopmental Disorders (MIND) Institute, University of California Davis, 2825 50th Street, Sacramento, CA, 95817, USA.

There is increasing recognition of the heterogeneity of origin of cases of autism spectrum disorder (ASD) with multiple forms of ASD having been identified over the decades. Among these, a genetic etiology can be identified in 20-40% of cases when a full genetic work-up is completed. The Fragile X premutation state (characterized by the presence of 55-200 CGG repeats in the FMR1 gene) is a relatively newly identified disease state that has since been associated with several disorders including fragile X-associated tremor ataxia syndrome (FXTAS), fragile X-associated primary ovarian insufficiency (FXPOI) and most recently, fragile X-associated neurodevelopmental disorders (FXAND) which commonly includes anxiety and depression.

Human Ovarian Follicles Xenografted in Immunoisolating Capsules Survive Long Term Implantation in Mice.

Front Endocrinol (Lausanne) 2022 3;13:886678. Epub 2022 Jun 3.

Department of Biomedical Engineering, University of Michigan, Ann Arbor, MI, United States.

Female pediatric cancer survivors often develop Premature Ovarian Insufficiency (POI) owing to gonadotoxic effects of anticancer treatments. Here we investigate the use of a cell-based therapy consisting of human ovarian cortex encapsulated in a poly-ethylene glycol (PEG)-based hydrogel that replicates the physiological cyclic and pulsatile hormonal patterns of healthy reproductive-aged women. Human ovarian tissue from four donors was analyzed for follicle density, with averages ranging between 360 and 4414 follicles/mm. Read More

Reproductive Health in Chronic Kidney Disease: The Implications of Sex and Gender.

Semin Nephrol 2022 Mar;42(2):142-152

Nephrologie, Centre Hospitalier Le Mans, Le Mans, France.

Chronic kidney disease (CKD) is frequently accompanied by reproductive health challenges in females and males alike. Progression of CKD is associated with escalating impairment of the hypothalamic-pituitary-gonadal axis, which facilitates evolving ovarian, testicular, and sexual dysfunction. Common clinical reproductive health complications in CKD include abnormal menstruation, impaired sexual health, and reduced fertility. Read More

The Role of mA on Female Reproduction and Fertility: From Gonad Development to Ovarian Aging.

Front Cell Dev Biol 2022 30;10:884295. Epub 2022 May 30.

State Key Laboratory of Reproductive Medicine, Gusu School, Suzhou Municipal Hospital, Suzhou Affiliated Hospital of Nanjing Medical University, Nanjing Medical University, Suzhou, China.

The growth and maturation of oocyte is accompanied by the accumulation of abundant RNAs and posttranscriptional regulation. N6-methyladenosine (mA) is the most prevalent epigenetic modification in mRNA, and precisely regulates the RNA metabolism as well as gene expression in diverse physiological processes. Recent studies showed that mA modification and regulators were essential for the process of ovarian development and its aberrant manifestation could result in ovarian aging. Read More

Protective Effects of Antioxidants on Cyclophosphamide-Induced Ovarian Toxicity.

Biopreserv Biobank 2022 Jun 13. Epub 2022 Jun 13.

Nucleus of Biotechnology Applied to Ovarian Follicle Development, Department of Veterinary Medicine, Federal University of São Francisco Valley-UNIVASF, Petrolina, Brazil.

The most common limitation of anticancer chemotherapy is the injury to normal cells. Cyclophosphamide, which is one of the most widely used alkylating agents, can cause premature ovarian insufficiency and infertility since the ovarian follicles are extremely sensitive to their effects. Although little information is available about the pathogenic mechanism of cyclophosphamide-induced ovarian damage, its toxicity is attributed to oxidative stress, inflammation, and apoptosis.

Bioengineering trends in female reproduction: a systematic review.

Hum Reprod Update 2022 Jun 2. Epub 2022 Jun 2.

Fundación IVI, IVI-RMA Global, Valencia, Spain.

Background: To provide the optimal milieu for implantation and fetal development, the female reproductive system must orchestrate uterine dynamics with the appropriate hormones produced by the ovaries. Mature oocytes may be fertilized in the fallopian tubes, and the resulting zygote is transported toward the uterus, where it can implant and continue developing. The cervix acts as a physical barrier to protect the fetus throughout pregnancy, and the vagina acts as a birth canal (involving uterine and cervix mechanisms) and facilitates copulation. Read More

Association of Beta-Thalassaemia and Hypogonadotropic Hypogonadism.

Case Rep Obstet Gynecol 2022 19;2022:4655249. Epub 2022 May 19.

Department of Obstetrics and Gynecology, Lucerne Cantonal Hospital, Switzerland.

Thalassaemic syndromes are among the most common haemoglobinopathies and are associated with high morbidity and mortality. Because of the various treatments, a secondary endocrinopathy due to iron overload-haemosiderosis-can occur, causing hypopituitarism leading to hypogonadotropic hypogonadism (HH) and infertility. We present a case of secondary amenorrhoea in a patient with beta-thalassaemia and a history of multiple therapies in her adolescence, such as multiple transfusions, chemotherapy, and allogeneic bone marrow transplantation, who presented with HH and premature ovarian insufficiency.

Rev Bras Ginecol Obstet 2022 May 26. Epub 2022 May 26.

Gynecology Department, Universidade Estadual Paulista "Júlio de Mesquita Filho", Botucatu, SP, Brazil.

Objective:  The present study aimed to develop a useful mathematical model that predicts the age at which premature ovarian insufficiency might occur after teletherapy radiation. A diagnosis of premature or early menopause has physical and psychological consequences, so women may need support and long-term medical follow-up.
