Discordance between day-3 follicle stimulating hormone & anti-Müllerian hormone is predictive of clinical pregnancy during fertility treatment.

OBJECTIVE: To evaluate the role of discordant Day-3 follicle stimulating hormone (FSH) & anti-Müllerian hormone (AMH) levels in predicting pregnancy outcome after controlled ovarian stimulation (COS) followed by intrauterine insemination or timed intercourse. METHODS: Retrospective study of 745 couples with regular menstrual cycles, at least one patent fallopian tube, and normal semen analysis that underwent infertility treatment between June 2013 and March 2017. Women with documented serum AMH and FSH levels (<10 (mIU/ml were considered normal), and undergo COS were studied. Clinical pregnancy rate is the cumulative pregnancy obtained after maximum of three cycles of COS with or without IUI. RESULTS: As expected, patients with normal concordant AMH/FSH achieved a significantly (p < .01) higher pregnancy than all other groups. 22.4% of those with discordant normal AMH/abnormal FSH became pregnant while only 10.8% of those with discordant abnormal AMH/normal FSH levels did. 11.7% of patients with abnormal concordant values achieved pregnancy. Patients with discordant abnormal AMH/normal FSH were not statistically different (p = .084) from abnormal concordance AMH/FSH but significantly (p < .01) lower than normal concordant AMH/FSH. However, patients with discordant normal AMH/abnormal FSH were statistically different from both concordant normal and concordant abnormal AMH/FSH values (p < .04). CONCLUSIONS: This study showed that both discordant abnormal Day-3 FSH and/or abnormal AMH serum levels, as well as concordant abnormal FSH and AMH values, were predictive of lower clinical pregnancy rates after COS. However, abnormal FSH with a normal AMH does not have as poor a prognosis as the presence of an abnormal AMH.

Serum tumor necrosis factor-α, interleukin-6, monocyte chemotactic protein-1 and paraoxonase-1 profiles in women with endometriosis, PCOS, or unexplained infertility.

OBJECTIVE: To investigate the serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), and Paraoxonase-1 (PON-1) during fertility treatment of women with endometriosis (Endo), PCOS or unexplained infertility (Unexpl). METHODS: Thirty-six patients with Endo, PCOS or Unexpl undergoing controlled ovarian stimulation for IVF or IUI were consented and their serum, on day-3 (baseline) and at the end of FSH treatment (peak), was collected and investigated for levels of TNF-α, IL-6, MCP-1, and PON-1. Correlations, ANOVA and Student's t-test were used for statistical analysis. RESULTS: Peak serum levels of IL-6, MCP-1 and PON-1 were positively correlated to E2 peak levels. TNF-α levels were inversely correlated to estradiol levels and they were lower in patients who ultimately became pregnant when compared to non-pregnant (P < 0.05). Mean TNF-α levels were significantly higher in Unexpl group (P < 0.05). The mean levels of IL-6, and MCP-1 were significantly (p < 0.05) higher in women with PCOS compared with Endo and Unexpl. No differences were found between the three clinical groups in patient's age, BMI, Day-3 FSH, PON-1 and pregnancy outcome. CONCLUSION: Circulating cytokine levels were influenced by ovarian stimulation, as demonstrated by increased levels of IL-6, MCP-1 and PON-1, and decreased level of TNF-α at the end of controlled ovarian stimulation. While evidence of relationship between circulating cytokines with mild endometriosis was not found, PCOS was associated with elevated serum IL-6 and MCP-1 but lower TNF-α concentration. Unexplained infertility was associated with elevated TNF-α level. No relationship between serum PON-1 concentration and PCOS, mild endometriosis or unexplained infertility was noted.

Severe late-onset ovarian hyperstimulation syndrome presenting with liver dysfunction after in vitro fertilization: A case report.

Ovarian hyperstimulation syndrome (OHSS) is a feared complication of controlled ovarian stimulation (COS) and can be associated with significant morbidity and mortality. Risk factors for OHSS include a history of OHSS, young age, low body mass index (BMI), polycystic ovary syndrome, elevated serum levels of anti-Müllerian hormone (AMH), large number of recruited follicles, elevated serum levels of estradiol, and higher gonadotropin doses during COS. However, OHSS may develop in patients with minimal risk factors. We present the case of a patient with minimal risk factors who developed severe late-onset OHSS in early pregnancy with liver dysfunction requiring hospitalization. After hospital discharge, her pregnancy resulted in a term live birth. We recommend that clinicians include OHSS in the differential diagnosis of elevated levels of liver enzymes in early pregnancy.

Semantic Assessment of the Barkin Index of Maternal Functioning in a Medically Underserved Obstetric Population.

PURPOSE: This study aims to evaluate the fitness of the Barkin Index of Maternal Functioning (BIMF) for postpartum functional assessment in a low-income obstetric population in medically underserved, Central Georgia (USA). DESIGN AND METHODS: Cognitive interviewing, a best practices approach to instrument development and validation, was performed on 24 new mothers. FINDINGS: The BIMF was comprehensible to this population of disadvantaged women. PRACTICE IMPLICATIONS: The BIMF has broad appeal due to its comprehensibility, patient-centered assessment style, and psychometric profile. Method of questionnaire administration and characteristics of the study and/or patient population should routinely be considered when implementing any type of self-reported health screening.

Adult reserve stem cells and their potential for tissue engineering.

Tissue restoration is the process whereby multiple damaged cell types are replaced to restore the histoarchitecture and function to the tissue. Several theories have been proposed to explain the phenomenon of tissue restoration in amphibians and in animals belonging to higher orders. These theories include dedifferentiation of damaged tissues, transdifferentiation of lineage-committed progenitor cells, and activation of reserve precursor cells. Studies by Young et al. and others demonstrated that connective tissue compartments throughout postnatal individuals contain reserve precursor cells. Subsequent repetitive single cell-cloning and cell-sorting studies revealed that these reserve precursor cells consisted of multiple populations of cells, including tissue-specific progenitor cells, germ-layer lineage stem cells, and pluripotent stem cells. Tissue-specific progenitor cells display various capacities for differentiation, ranging from unipotency (forming a single cell type) to multipotency (forming multiple cell types). However, all progenitor cells demonstrate a finite life span of 50 to 70 population doublings before programmed cell senescence and cell death occurs. Germ-layer lineage stem cells can form a wider range of cell types than a progenitor cell. An individual germ-layer lineage stem cell can form all cells types within its respective germ-layer lineage (i.e., ectoderm, mesoderm, or endoderm). Pluripotent stem cells can form a wider range of cell types than a single germ-layer lineage stem cell. A single pluripotent stem cell can form cells belonging to all three germ layer lineages. Both germ-layer lineage stem cells and pluripotent stem cells exhibit extended capabilities for self-renewal, far surpassing the limited life span of progenitor cells (50-70 population doublings). The authors propose that the activation of quiescent tissue-specific progenitor cells, germ-layer lineage stem cells, and/or pluripotent stem cells may be a potential explanation, along with dedifferentiation and transdifferentiation, for the process of tissue restoration. Several model systems are currently being investigated to determine the possibilities of using these adult quiescent reserve precursor cells for tissue engineering.

Clonogenic analysis reveals reserve stem cells in postnatal mammals. II. Pluripotent epiblastic-like stem cells.

Undifferentiated cells have been identified in the prenatal blastocyst, inner cell mass, and gonadal ridges of rodents and primates, including humans. After isolation these cells express molecular and immunological markers for embryonic cells, capabilities for extended self-renewal, and telomerase activity. When allowed to differentiate, embryonic stem cells express phenotypic markers for tissues of ectodermal, mesodermal, and endodermal origin. When implanted in vivo, undifferentiated noninduced embryonic stem cells formed teratomas. In this report we describe a cell clone isolated from postnatal rat skeletal muscle and derived by repetitive single-cell clonogenic analysis. In the undifferentiated state it consists of very small cells having a high ratio of nucleus to cytoplasm. The clone expresses molecular and immunological markers for embryonic stem cells. It exhibits telomerase activity, which is consistent with its extended capability for self-renewal. When induced to differentiate, it expressed phenotypic markers for tissues of ectodermal, mesodermal, and endodermal origin. The clone was designated as a postnatal pluripotent epiblastic-like stem cell (PPELSC). The undifferentiated clone was transfected with a genomic marker and assayed for alterations in stem cell characteristics. No alterations were noted. The labeled clone, when implanted into heart after injury, incorporated into myocardial tissues undergoing repair. The labeled clone was subjected to directed lineage induction in vitro, resulting in the formation of islet-like structures (ILSs) that secreted insulin in response to a glucose challenge. This study suggests that embryonic-like stem cells are retained within postnatal mammals and have the potential for use in gene therapy and tissue engineering.

Barriers to optimal social support in the postpartum period.

OBJECTIVE: To examine the specific barriers to mothers' realization of social support during the first-year postpartum. DESIGN: A qualitative approach in which social support data were analyzed thematically. SETTING: An urban medical center in Pittsburgh, Pennsylvania. PARTICIPANTS: Thirty-one women who had given birth in the year prior to study enrollment were recruited through posted flyers at multiple community sites. METHODS: Data were collected during three focus groups. The data that related to social support were extracted from a larger qualitative data set and analyzed separately for prominent social support inhibitors. RESULTS: Major themes that emerged were availability of trustworthy child care, cost of child care, demands of infant care, changing priorities, a transient population, and availability of family. CONCLUSIONS: Emergent barriers to social support such as the demands of infant care and changing priorities are likely challenges for women regardless of socioeconomic status. However, the volume of text related to availability (proximity) of family, availability of trustworthy child care, and the consequences of a transient lifestyle may be attributed to the composition of the study sample.

Adult-derived stem cells and their potential for use in tissue repair and molecular medicine.

This report reviews three categories of precursor cells present within adults. The first category of precursor cell, the epiblast-like stem cell, has the potential of forming cells from all three embryonic germ layer lineages, e.g., ectoderm, mesoderm, and endoderm. The second category of precursor cell, the germ layer lineage stem cell, consists of three separate cells. Each of the three cells is committed to form cells limited to a specific embryonic germ layer lineage. Thus the second category consists of germ layer lineage ectodermal stem cells, germ layer lineage mesodermal stem cells, and germ layer lineage endodermal stem cells. The third category of precursor cells, progenitor cells, contains a multitude of cells. These cells are committed to form specific cell and tissue types and are the immediate precursors to the differentiated cells and tissues of the adult. The three categories of precursor cells can be readily isolated from adult tissues. They can be distinguished from each other based on their size, growth in cell culture, expressed genes, cell surface markers, and potential for differentiation. This report also discusses new findings. These findings include the karyotypic analysis of germ layer lineage stem cells; the appearance of dopaminergic neurons after implantation of naive adult pluripotent stem cells into a 6-hydroxydopamine-lesioned Parkinson's model; and the use of adult stem cells as transport mechanisms for exogenous genetic material. We conclude by discussing the potential roles of adult-derived precursor cells as building blocks for tissue repair and as delivery vehicles for molecular medicine.
