Acceptability of self-sampling and human papillomavirus testing among non-attenders of cervical cancer screening programs in El Salvador.

In a cross-sectional study carried out in El Salvador between February 2016 and July 2017, self-sampling and human papillomavirus (HPV) testing was found to be highly acceptable among 2019 women who had not attended a cervical cancer screening in at least 3 years. Within this population, HPV positivity rates differed according to age, marital status, number of children, and lifetime sexual partners. The proportion of women who tested HPV positive or who were diagnosed with cervical intraepithelial neoplasia grade 2 (CIN2) or more severe diagnoses (CIN2+) was similar to the general population of the area. Among the reasons for failing to participate in previous screening programs, non-attending women described logistic concerns, but also erroneous beliefs regarding HPV and cervical cancer, misconceptions regarding the screening procedure, discomfort with male providers, and confidentiality fears. The aim of this study was to identify opportunities and challenges that emerged from the use of self-sampling and HPV testing as part of a public cervical cancer control effort in a low-resource setting.

Chinese herbal medicine for miscarriage affects decidual micro-environment and fetal growth.

INTRODUCTION: Intrauterine growth restriction complicates 5-10% of pregnancies. This study aims to test the hypothesis that Chinese herbal formula, JLFC01, affects pregnancy and fetal development by modulating the pro-inflammatory decidual micro-environment. METHODS: Human decidua from gestational age-matched elective terminations or incomplete/missed abortion was immunostained using anti-CD68 + anti-CD86 or anti-CD163 antibodies. qRT-PCR and Luminex assay measured the effects of JLFC01 on IL-1ß- or TNF-α-induced cytokine expression in first trimester decidual cells and on an established spontaneous abortion/intrauterine growth restriction (SA/IUGR)-prone mouse placentae. The effect of JLFC01 on human endometrial endothelial cell angiogenesis was evaluated by average area, length and numbers of branching points of tube formation. Food intake, litter size, fetal weight, placental weight and resorption rate were recorded in SA/IUGR-prone mouse treated with JLFC01. qRT-PCR, Western blot and immunohistochemistry assessed the expression of mouse placental IGF-I and IGF-IR. RESULTS: In spontaneous abortion, numbers of decidual macrophages expressing CD86 and CD163 are increased and decreased, respectively. JLFC01 reduces IL-1ß- or TNF-α-induced GM-CSF, M-CSF, C-C motif ligand 2 (CCL2), interferon-γ-inducible protein-10 (IP-10), CCL5 and IL-8 production in first trimester decidual cells. JLFC01 suppresses the activity of IL-1ß- or TNF-α-treated first trimester decidual cells in enhancing macrophage-inhibited angiogenesis. In SA/IUGR-prone mice, JLFC01 increases maternal food intake, litter size, fetal and placental weight, and reduces fetal resorption rate. JLFC01 induces IGF-I and IGF-IR expression and inhibits M-CSF, CCL2, CCL5, CCL11, CCL3 and G-CSF expression in the placentae. DISCUSSION: JLFC01 improves gestation by inhibiting decidual inflammation, enhancing angiogenesis and promoting fetal growth.

Emergency contraception: past, present and future.

Women have been using emergency contraception (EC) for decades. Population studies have not shown that increased access to EC decreases abortion rates this is likely because of inconsistent and infrequent use even when it is available. Special populations, such as adolescents, have been shown to be just as good as their adult counterparts in comprehending EC instructions, and its use does not lead to more risky sexual practices or behaviors. There is little evidence on the administration of EC to victims of sexual assault, but what is available reveals more women who are victims of sexual assault should be offered EC as an option. Methods of EC include high doses of ethinyl estradiol; DES; Danzaol; combination ethinyl estradiol with a progestin; progestin alone and copper IUDs. This review describes the history of EC as well as newer medications such as the antiprogestins (gestrinone and uliprisatal acetate) and cyclooxygenase inhibitors(meloxifam). These methods have been added to the armamentarium and may prove to be more effective than current regimens. Finding a product that is highly effective with minimal side effects is a worthy goal, for it presents a woman with her last chance to prevent an unwanted pregnancy.

A cellular study of human testis development.

This study catalogs the cellular events underlying the formation of a human testis. These events were identified by immunocytochemistry using antibodies that served as markers for specific cell types, then contrasted with the events occurring in the developing mouse testis. The presence of germ cells in the embryonic gonadal ridge and of coelomic epithelial cells that give rise to Sertoli cells was observed at 7 weeks. This was followed by the appearance of Sertoli cells in testicular tubules and of Leydig cells at 9 weeks and by the appearance of vascular endothelial cells and peritubular myoid cells at 12 weeks. Overall the temporal sequence of events in humans was similar, albeit longer, than what occurs in mice. Notably, Leydig cell differentiation occurs earlier in the sequence of events and germ cell maturation occurs during fetal life. The candidate testis-determining genes, FGF9, GATA4, FOG2, EMX2, and CBX2 were expressed at 7 weeks suggesting a role in early gonadal development, such as that observed in mice. In addition, expression of FGF9 in germ cells following testis determination suggests a role in germ cell maturation.

Regulation of chemokine production in response to pro-inflammatory cytokines in first trimester decidual cells.

OBJECTIVE: Chemokines initiate the immune response by controlling leukocyte migration and lymphocyte development. Macrophage infiltration of the decidua has been implicated in the genesis of recurrent miscarriage and preeclampsia. Therefore, we determined whether cultured human decidual cells produce monocyte/macrophage-recruiting chemokines in response to a potent pro-inflammatory cytokine, interleukin-1beta (IL-1beta), and whether decidual cell-conditioned medium contains monocyte- and macrophage-chemoattractant activity. METHODS: Leukocyte-free first trimester decidual cells were treated for 6h with estradiol (E(2)) and medroxyprogesterone acetate (MPA) to mimic the steroidal milieu of pregnancy, or E(2) and MPA and IL-1beta (1 ng/ml) to mimic inflamed decidua. Total RNA was used for cDNA synthesis. Biotinylated cRNAs were generated and chemically fragmented for hybridization on Affymetrix HG_U133 Plus 2.0 chips followed by fluorescence labeling and optical scanning. Raw data generated from Affymetrix GCOS 1.2 (GeneChip Operating Software) were analyzed by GeneSpring 7.2 software. Subsequently microarray results were validated by real time RT-PCR and Western blotting. A functional study of monocyte migration was carried out also using conditioned media from culture. RESULTS: Five chemokines responsible for monocyte/macrophage chemoattraction and activation, including C-C motif ligand 2 (CCL2), CCL5, C-X-C motif ligand 2 (CXCL2), CXCL3 and CXCL8, were markedly elevated from 29- to 975-fold after exposure to IL-1beta in cultured first trimester decidual cells. The results of real-time RT-PCR (up-regulation from 43- to 3069-fold) and Western blotting (up-regulation from 15- to 300-fold) confirmed the microarray findings. Monocyte migration was significantly induced by the conditioned medium from IL-1beta-treated decidual cells. CONCLUSIONS: Treatment of first trimester decidual cells with IL-1beta induces secretion of monocyte/macrophage recruiting-chemokines and promotes monocyte migration. Extrapolation of these in vitro results to the milieu of implantation site suggests a mechanism whereby IL-1beta could mediate excessive macrophage infiltration of the decidua.

Urinary incontinence in gynecological oncology patients.

The objective of this study was to investigate the prevalence and significance of urinary incontinence (UI) symptoms in gynecological oncology (GO) patients and to test the gynecologists' proficiency in eliciting these symptoms. A prospective survey using questionnaires was designed. Two faculty practice offices in the United States were chosen for the study. Forty GO patients and 40 general gynecology patients were selected from the most recent outpatient appointments of the two hospitals. We used the Urogenital Distress Inventory and the Incontinence Impact Questionnaire to elicit UI symptoms in GO patients and compared the results with their medical records. A control group, selected from a general gynecological practice, was included for comparison. The main outcome measures were to investigate the prevalence and detection rates of UI in GO patients. GO patients were significantly more likely to report UI symptoms on the questionnaire than their gynecologist was able to elicit during a consultation (P < 0.001). The survey found that 60% (24/40) of the GO patients reported at least one symptom of UI, with 23% complaining of "severe" symptoms. Of those patients who reported the symptoms on questionnaire, only 5% (2/40) were detected at the initial physician assessment (P < 0.01). Eighteen percent of the GO patients reported that the UI symptoms adversely affected their quality of life. The prevalence of symptoms was not associated with the primary cancer site. There was no difference in detection rates between the two practice settings. In a multivariate analysis, there was no factor that emerged as the best discriminator for a positive response to the questionnaire. A significant proportion of GO patients report severe UI symptoms that are not detected by gynecologic oncologists or gynecologists during routine consultations.
