RESUMEN

The solubilization behavior of medroxyprogesterone (MP) within gemini surfactant micelles (14-6-14,2Br-) was investigated and compared with that of progesterone to uncover distinct solubilization mechanisms. We employed 1H-NMR and 2D ROESY spectroscopy to elucidate the spatial positioning of MP within the micelle, revealing that MP integrates more deeply into the micellar core. This behavior is linked to the unique structural features of MP, particularly its 17ß-acetyl group, which promotes enhanced interactions with the hydrophobic regions of the micelle, while the 6α-methyl group interacts with the hydrophilic regions of the micelle. The 2D ROESY correlations specifically highlighted interactions between the hydrophobic chains of the surfactant and two protons of MP, H22 and H19. Complementary machine learning and electron density analyses supported these spectroscopic findings, underscoring the pivotal role of the molecular characteristics of MP in its solubilization behavior. These insights into the solubilization dynamics of MP not only advance our understanding of hydrophobic compound incorporation in gemini surfactant micelles but also indicate the potential of 14-6-14,2Br- micelles for diverse drug delivery applications.

RESUMEN

BACKGROUND AND OBJECTIVE: Unintended pregnancies occur more frequently in college students and negatively affect health outcomes and educational attainment. This study examined access to on-campus contraceptives at all 4-year colleges and universities in North Carolina (NC). METHODS: This institutional review board-exempt study evaluated availability of on-campus contraceptives including condoms; hormonal contraceptives including pills, patches, and vaginal rings; medroxyprogesterone injections; implants; intrauterine devices; and emergency contraception via website review. Institutions were stratified by characteristics including size, location, type (e.g., public, private, religious affiliation, historically black colleges and universities, women's colleges), and presence of a student health pharmacy. Comparisons were made using chi-square test or Fisher's exact test. RESULTS: Fifty-four 4-year colleges and universities were identified. A plurality or the majority of schools were considered small (41%) and urban (48%) and had a religious affiliation (61%). Thirty-three percent of colleges and universities had an on-campus pharmacy. The most frequent contraceptives offered were condoms (43%), oral contraceptives (33%), and medroxyprogesterone injections (22%). Emergency contraception was available at approximately one-third of colleges and universities. Six percent of institutions provided a full range of contraceptive methods. Contraceptives were offered more frequently at large, public, urban institutions, whereas religious institutions and smaller institutions were less likely to offer contraceptives. CONCLUSION: Access to on-campus contraception for college students in NC is lacking, and the vast majority of institutions did not provide a full range of contraceptives. Policy measures, such as enhancing reproductive health services at student health centers or increasing contraception availability directly through pharmacies, are needed to improve access for college students.

RESUMEN

Depot medroxyprogesterone acetate causes a hypo-estrogenic state in over half of users although clinical vaginal atrophy causing superficial dyspareunia is thought rarely to occur. This is a case series of ten women using depot medroxyprogesterone acetate who presented with superficial dyspareunia and clinical vaginal atrophy. The women were treated with vaginal estriol cream and their contraception was discontinued or changed. All patients had either a complete resolution of symptoms or a substantial improvement at follow-up, and the clinical and laboratory findings of vaginal atrophy had resolved. This case series demonstrates that vaginal atrophy may occur more frequently than previously thought.

RESUMEN

BACKGROUND: Pregnancy is the second most common cause of limited duty days among active duty service members in the U.S. Military. Pregnancy accounts for 10% of all days on restricted duty, despite impacting a minority of active duty service members. One out of five service women will experience an unintended pregnancy every year despite the availability of no-cost contraception and reproductive healthcare. Young, single, junior enlisted service women experience the highest rate of unintentional pregnancy. Previous studies have demonstrated service branch-based variability in selection, initiation, and continuation of specific contraceptive methods related to service branch culture and access to contraception during basic training. It is unclear if these differences impact overall contraception use or fertility rates among junior enlisted service women in their first term of enlistment. This study examines rates of contraceptive selection, initiation, continuation, and efficacy among junior enlisted service women in their first 4-year enlistment period, and the service branch specific variability in these outcomes. METHODS: This study is a secondary analysis of Military Healthcare Data Repository records from women who began basic training between 2012 and 2020 and remained on active duty for at least 12 months. We used Kaplan-Meier analyses to examine the effect of age and military branch on contraceptive continuation and efficacy. We used binomial regression for interval censored data, to assess the association of service branch with rates of contraceptive initiation, contraception use, births, and childbirth-related duty restrictions. RESULTS: We identified 147,594 women who began basic training between 2012 and 2020. The mean age of these women at the beginning of basic training was 20.4 ± 3.1 years. Women in the marines and navy had higher contraceptive initiation rates than women in the army or air force. Among women initiating a contraceptive pill, patch, or ring (short-acting reversible contraception), 58.3% were still using some form of hormonal contraception 3 months later. Among women initiating depot-medroxyprogesterone (DMPA), 38.8% were still using any form of hormonal contraception 14 weeks later. Long-acting reversible contraceptive methods, such as intrauterine or subdermal contraceptives, had higher continuation rates and less service-based variability in continuation and failure rates than short-acting reversible contraception or depot-medroxyprogesterone. The proportion of days on any form of prescription contraception during the first 4 years on active duty varied from 23.3% in the army to 38.6% in the navy. The birth rate varied from 34.8 births/1,000 woman-years in the air force up to 62.7 births/1,000 woman-years in the army. Compared with women in the air force, women in the army experienced 2,191 additional days of postpartum leave and 13,908 days on deployment restrictions per 1,000 woman-years. DISCUSSION: Service branch specific variability in contraceptive use is associated with differences in days of pregnancy-related duty restrictions during first 4 years on active duty among junior enlisted females. Robust implementation of best practices in contraceptive care across the military health system to improve contraceptive initiation and continuation appears to offer an opportunity to improve military readiness and promote the health and well-being of active duty service women, particularly in the army.

RESUMEN

BACKGROUND/AIM: Hormonal treatment is the preferred initial systemic therapy for patients with advanced or recurrent G1 or G2 endometrial cancer (EC) in terms of efficacy, toxicity, and economy. Few reports are available on the topic and we, therefore, conducted a retrospective study. PATIENTS AND METHODS: Patients with EC who received high-dose medroxyprogesterone (MPA) at our Hospital between January 2010 and December 2022 were reviewed. Patients who were treated for fertility preservation or had a history of systemic chemotherapy other than adjuvant therapy were excluded. RESULTS: Sixteen patients who were eligible for study inclusion had recurrent G1 or G2 EC. Their median age was 65 years (range=51-82 years), median body mass index was 22.6 kg/m2 (range=15.3-43.2 kg/m2), and all patients had an ECOG Performance Status of 0. All patients received 200 mg/day of MPA, and eight patients concomitantly received 100 mg/day of aspirin. None of the patients experienced severe adverse events. One patient had grade 2 deep vein thrombosis. Two patients discontinued MPA treatment because of adverse events. The response rate was 44% [95% confidence interval (CI)=20-68%] and median progression-free survival (PFS) was 6.9 months (95% CI=7.5-26 months). Four of 16 patients had PFS longer than 12 months, all of whom had positive tissue estrogen receptor (ER) and progesterone receptor (PR), and PFS at 2 years was 35% (95% CI=10.2-59.8%). CONCLUSION: Hormone therapy is effective long-term in ER- and PR-positive EC and can be recommended as initial systemic therapy. Toxicity is mild and manageable.

RESUMEN

The anti-cancer properties of plasma-treated solutions (PTS) and their interaction with drugs are one of the most popular topics in modern plasma medicine. Our research involved comparing the effects of four physiological saline solutions (0.9% NaCl, Ringer's solution, Hank's Balanced Salt Solution, Hank's Balanced Salt Solution with amino acids added in concentrations observed in the human blood) treated with cold atmospheric plasma and studying the combined cytotoxic effect of PTS with doxorubicin and medroxyprogesterone acetate (MPA). Analysis of the effect of the studied agents on the formation of radicals in the incubation medium, the vitality of K562 myeloid leukaemia cells, and the processes of autophagy and apoptosis in them revealed two key findings. The first is that when using PTS and doxorubicin-containing PTS, autophagy is the predominant process in cancer cells. The second is that combining PTS with MPA enhances apoptotic processes. It was hypothesised that while autophagy is stimulated by the accumulation of reactive oxygen species in the cell, apoptosis is stimulated through specific cell progesterone receptors.

RESUMEN

BACKGROUND: Only old evidence exists to back up the use of medroxyprogesterone acetate. Therefore, this study aimed to explore the factors that influence the time to treatment failure of medroxyprogesterone acetate in real-world settings as late-line treatment. METHODS: This was a cohort study that used the database of the Safari study on oestrogen receptor-positive post-menopausal advanced breast cancer (UMIN000015168). We created Kaplan-Meier curves for time to treatment failure with medroxyprogesterone acetate. Further, univariate and multivariate analyses were performed using a Cox hazard model of the clinicopathological factors involved in the time to treatment failure of medroxyprogesterone acetate. RESULTS: From the 1031 patients in the Safari study, 279 patients were selected as the population for the analysis of effectiveness of medroxyprogesterone acetate monotherapy. In the analysis of medroxyprogesterone acetate by treatment line, the median time to treatment failure was 3.0 months for third-line treatment and 4.1 months for fourth and subsequent treatment lines. In cases where medroxyprogesterone acetate was used as a third-line or later endocrine treatment, multivariate analysis showed that the length of the disease-free interval was correlated with the length of time to treatment failure of medroxyprogesterone acetate (P = 0.004). With medroxyprogesterone acetate monotherapy as the fourth-line or later treatment, 20% of the patients achieved a time to treatment failure of 12 months or longer. CONCLUSION: In actual clinical practice, patients treated with medroxyprogesterone acetate alone as the fourth or subsequent treatment lines showed a time to treatment failure of 4 months, suggesting that there is merit in using medroxyprogesterone acetate even in late treatment lines, especially in patients with long disease-free interval and those who are difficult to treat using other antineoplastic agents.

RESUMEN

Surface water provides ecological services such as drinking water supply. However, contaminants of emerging concern (CECs) are rising concerns because they are ubiquitously detected in surface water and pose potential risks to the aquatic environment and human health. This study investigated the occurrence of 165 CECs in surface water from drinking water source areas along the lower reaches of the Yangtze River to prioritize the CECs and to estimate potential biological activity based on exposure-activity ratio (EAR). A total of 70 CECs were detected in the surface water at least once at the selected 17 sampling sites, and their concentrations ranged from 0.592 to 4650 ng/L. Twenty-four CECs were detected at each site, and these were mostly pharmaceutical and personal care products and pesticides. Sucralose, 1H-benzotriazole and carbendazim were the most common CECs with high median concentrations in the study area. Specifically, sucralose, an artificial sweetener, was presented at each site with the highest median concentration (3010 ng/L), which indicated that anthropogenic inputs are an important source of contaminants. Medroxyprogesterone and trenbolone were identified as the priority contaminants of interest, with maximum EARchemical values of 0.389 and 0.183, respectively. Among all the sites, the higher cumulative EARmixture value was found from Nantong City (0.765), which indicated that this site could have a relatively greater potential for biological effects, and these effects were mainly due to medroxyprogesterone and trenbolone. In regard to the bioactivity of all detected CECs, nuclear receptors showed the greatest potential bioactivity in this region, particularly androgen receptor-mediated bioactivity, which is most likely affected organisms residing in the source water area. These results suggest that the drinking water sources from the studied region are contaminated with CECs, and highlight the prioritization of future monitoring and research to protect source waters.

RESUMEN

Objective: The purpose of this study was to evaluate the impact of isoflavone supplementation compared with placebo on endometrial histology and serum estradiol levels in premenopausal women with nonatypical endometrial hyperplasia. Materials and Methods: The present double-blindplacebo-controlled clinical trial was conducted on 100 women with nonatypical endometrial hyperplasia in the age range of 30 to 45 years. Participants were randomly assigned to receive 50 mg of isoflavone (n = 50) or placebos (n = 50) daily for three months. Both groups received the standard treatment of nonatypical endometrial hyperplasia. Endometrial biopsy and blood samples were taken at the baseline and three months after the intervention. The incidence of drug side effects was assessed as well. Results: After three months, 88.4% of isoflavone-administered subjects had a significant histological improvement compared to 68.9% subjects in the placebo group (P=0.02). There were no significant differences between the two groups in the changes of serum estradiol levels and the incidence of drug side effects. Conclusion: The findings of the present study demonstrated that the coadministration of 50 mg of isoflavones and medroxyprogesterone acetate increases the treatment efficacy in women with nonatypical endometrial hyperplasia. Clinical Trial Registration. This trial was registered on the Iranian website for clinical trial registration (https://www.irct.ir/trial/53553).

RESUMEN

Objective: To study the effect of Mirena intrauterine device (IUD) on endometrial thickness, life quality score, and curative effect in patients with perimenopausal abnormal uterine bleeding. Methods: Eighty patients with perimenopausal abnormal uterine bleeding cured from January 2020 to December 2021 were enrolled as the object of study. According to random number table, the patients were classified into the study (n = 40) and control (n = 40) groups. The control cases were cured with medroxyprogesterone. The study cases were cured with Mirena IUD. The effective rate of clinical therapies was evaluated after 3 months of treatment. The endometrial thickness, menstrual volume score, and life quality score (WHOQOL-BREF) was measured after 1 month, 2 months, and 3 months of treatment. Results: The effective rate of patients with Mirena IUD for 3 months was higher compared to the control group (P < 0.05). The endometrial thickness and menstrual volume scores of study cohort after 1 month, 2 months, and 3 months following treatment were remarkably lower than those before treatment (P < 0.05) and were considerably lower than those of control cohort (P < 0.05). The hemoglobin level of the studied cases after 1 month, 2 months, and 3 months after therapy was remarkably upregulated (P < 0.05) and was greatly higher compared to the controlled cases (P < 0.05). After 3-month treatment, the WHOQOL-BREF score of the study group was higher compared to the control group (P < 0.05). Conclusion: The Mirena IUD is far more effective in the treatment of perimenopausal abnormal uterine bleeding and is helpful in reducing the thickness of the endometrium. Patients' menstrual flow can be controlled, and anemia can be corrected; thus, patients improve their quality of life and health status and can be considered for further promotion.

RESUMEN

Sickle cell disease (SCD) is associated with altered plasma and erythrocyte lipid profiles. In a previous study, SCD mice with deficiency of proprotein convertase subtilisin/kexin type 9 (PCSK9) were observed to have more severe anemia and increased sickling compared to control SCD mice. Although PCSK9 affects circulating low density lipoprotein (LDL) by regulation of the LDL receptor, the effect of PCSK9 on anemia was independent of LDL receptor expression. In the current study, erythrocyte metabolomics were performed and revealed altered erythrocyte lipid species between SCD mice with and without PCSK9. Of particular interest, the late endosome-specific lipid bis(mono)acylglycerol phosphate (BMP) 44:12 was markedly decreased in erythrocytes from SCD mice deficient in PCSK9 mice relative to control SCD mice. Incubation of sickle erythrocytes with a neutralizing antibody to BMP increased erythrocyte sickling in vitro. In vitro treatment of SCD erythrocytes with amiodarone (1.5 µM) or medroxyprogesterone (6.75 µM), two pharmacologic compounds known to increase BMP, resulted in reduced erythrocyte sickling. Treatment of SCD mice with amiodarone (10 mg/kg) for 2 weeks resulted in increased BMP, improvement in anemia with reduced reticulocytosis, and decreased ex vivo sickling. In conclusion, severity of anemia in SCD is improved with amiodarone treatment, an effect which may be mediated through increased erythrocyte BMP.

RESUMEN

OBJECTIVE: Investigate the association between use of depot medroxyprogesterone acetate (DMPA) (an injectable progestin-only contraceptive) and leiomyoma development. METHODS: We conducted a cohort study in the Detroit, Michigan, area that involved four clinic visits at 20-month intervals over 5 years (2010-2018) and used a standardized ultrasonography protocol to prospectively measure leiomyomas 0.5 cm or more in diameter. Participants were 1,693 self-identified Black women aged 23-35 years with no prior leiomyoma diagnosis and no hysterectomy. For this substudy, years since last use of DMPA was ascertained from questionnaire data at every visit. Leiomyoma incidence was defined as the first visit with an observed leiomyoma among women who were leiomyoma-free at enrollment. Depot medroxyprogesterone acetate associations were examined with Cox models. Leiomyoma growth was calculated as the change in log-volume for leiomyomas matched at successive visits and was modeled using linear mixed models accounting for clustered data. Leiomyoma loss, defined as a reduction in leiomyoma number in successive visits, was modeled using Poisson regression. All models used time-varying exposure and covariates. RESULTS: Of participants with at least one follow-up visit (N=1,610), 42.9% had ever used DMPA. Participants exposed to DMPA within the previous 2 years experienced reduced leiomyoma development during the subsequent observation interval compared with never users, including lower leiomyoma incidence (5.2% vs 10.7%), adjusted hazard ratio 0.6 (95% CI 0.4-1.0), 42.0% lower leiomyoma growth (95% CI -51.4 to -30.7) and 60% greater leiomyoma loss (adjusted risk ratio 1.6, 95% CI 1.1-2.2). Excess leiomyoma loss was also seen for those who used DMPA 2-4 years before the visit compared with never users, 2.1-fold increase (95% CI 1.4-3.1). CONCLUSION: Recent use of DMPA was associated with reduced leiomyoma development and increased leiomyoma loss. Such changes in early leiomyoma development in young women could delay symptom onset and reduce the need for invasive treatment.

RESUMEN

Contraceptives such as Depo-medroxyprogesterone (DMPA) are used by an estimated 34 million women worldwide. DMPA has been associated with increased risk of several viral infections including Herpes simplex virus-2 (HSV-2) and Human immunodeficiency virus (HIV). In the current study, we used the mouse papillomavirus (MmuPV1) anogenital infection model to test two hypotheses: (1) contraceptives such as DMPA increase the susceptibility of the anogenital tract to viral infection and (2) long-term contraceptive administration induces more advanced disease at the anogenital tract. DMPA treatments of both athymic nude mice and heterozygous NU/J (Foxn1nu/+) but ovariectomized mice led to a significantly increased viral load at the anogenital tract, suggesting that endogenous sex hormones were involved in increased viral susceptibility by DMPA treatment. Consistent with previous reports, DMPA treatment suppressed host anti-viral activities at the lower genital tract. To test the impact of long-term contraceptive treatment on the MmuPV1-infected lower genital tract, we included two other treatments in addition to DMPA: 17ß-estradiol and a non-hormone based contraceptive Cilostazol (CLZ, Pletal). Viral infections were monitored monthly up to nine months post infection by qPCR. The infected vaginal and anal tissues were harvested and further examined by histological, virological, and immunological analyses. Surprisingly, we did not detect a significantly higher grade of histology in animals in the long-term DMPA and 17ß-estradiol treated groups when compared to the control groups in the athymic mice we tested. Therefore, although DMPA promotes initial papillomavirus infections in the lower genital tract, the chronic administration of DMPA does not promote cancer development in the infected tissues in our mouse model.

RESUMEN

PURPOSE: This study aimed to improve the knowledge of low-grade endometrial stromal sarcoma (LG-ESS) with intracaval or intracardiac extension and tried to identify the potential risk factors and optimal treatment method influencing prognosis. METHODS: We performed a retrospective review of eight LG-ESS patients with intracaval or intracardiac extension who underwent treatment at Peking Union Medical College Hospital between 2012 and 2020. RESULTS: The median age at diagnosis was 44 years, ranging from 28 to 56 years. Abnormal uterine bleeding was the most common intimal symptom (3/8), followed by low back discomfort (2/8), edema of the lower limbs (2/8), abdominal pain (1/8), and dyspnea (1/8). All patients underwent resection of the intravascular and extravascular portions of the tumor. Two patients were in stage IIIC, and six were in stage IVB. After surgery, four patients received adjuvant radiotherapy, of whom three also received letrozole. One patient was treated with letrozole alone, and one patient received medroxyprogesterone. The average follow-up time was 34.5 months, ranging from 6 to 98 months. No patients died or relapsed during the follow-up period. CONCLUSIONS: LG-ESS with intracaval or intracardiac extension is an uncommon type of tumor which is easily misdiagnosed and can only be diagnosed by histological evaluation after surgery. Complete tumoral excision followed by adjuvant therapy may benefit patient survival time. Long-term follow-up is essential due to the high rate of late recurrence.

RESUMEN

OBJECTIVE: To describe use of three types of longer-acting contraception-intrauterine devices, subdermal contraceptives, and depot medroxyprogesterone-among transmasculine and cisgender women patients. STUDY DESIGN: A repeated cross-sectional study using electronic medical records of patients, age 18 to 45, receiving care within Kaiser Permanente Northern California between 2009 and 2019. Variations in demographics, clinical characteristics and contraception method uptake were assessed using t tests for continuous variables and chi-square tests for categorical variables for patients enrolled in 2019. A linear trend test for each group was used to assess the age-adjusted uptake of contraception methods by study year. RESULTS: The transmasculine group was younger, with a mean age of 27.3 years (±7.2) vs 32.5 years (±7.8) years, respectively p < 0.001. The transmasculine group used more tobacco, alcohol, and illicit drugs. The uptake of these contraception methods increased from 2009 to 2019 for both groups (transmasculine: 0.7% to 4.1%; cisgender: 5.6% to 6.7%) with a positive linear trend for both groups (p = 0.003 and p < 0.001, respectively). The change in uptake of any intrauterine device from 2009 to 2019 was greater for the transmasculine group (0.3% to 2.3% vs 3.3% to 3.5%). Etonogestrel implant uptake had a positive linear trend from 2009 to 2019 for both groups (transmasculine: 0% to 0.5%, p = 0.02, and cisgender 0.1% to 1.2%, p < 0.001). CONCLUSION: Annual uptake of these contraception methods increased significantly for both transmasculine and cisgender groups, and this increase was greater for the transmasculine patients. Uptake of these contraception methods was higher in the cisgender population. IMPLICATIONS: These findings suggest an improvement in use of long-term contraception and menstrual suppression medications for the transmasculine population. Further research is needed to understand these differences and identify a possible unmet need for intrauterine and subdermal contraceptives and depot medroxyprogesterone use among this often-marginalized population.

RESUMEN

OBJECTIVES: Females with sickle cell disease now have a life expectancy that extends well into and beyond their reproductive years. Pregnancy and childbirth are accompanied by high morbidity and mortality in this population, rendering contraception a critical part of their health care. STUDY DESIGN: We approached adult female patients of the Hospital of the University of Pennsylvania hematology clinic who were of reproductive age (ages 18-45) and carried a diagnosis of sickle cell disease. We evaluated contraceptive method uptake and method characteristic preferences, as well as other reproductive history, and compared contraceptive uptake rates to that from female respondent data from the National Survey of Family Growth (2017-2019). RESULTS: Of 95 eligible patients, we completed surveys with 48 participants (response rate of 51%). Over half (n = 27, 56%) of participants were not currently using any form of contraception-double the rate of the general United States population (25%). The most common contraceptives currently used were the depot medroxyprogesterone (DMPA) injection (n = 6, 13%) and the progestin intrauterine device (IUD) (n = 6, 13%). DMPA uptake was significantly higher, and permanent contraceptive and oral contraceptive pill uptake significantly lower, among these participants with sickle cell disease compared to the general United States population. Participants' preferred contraceptive characteristics included effectiveness (n = 39, 81%), control over when to use the contraceptive (n = 39, 81%), and lack of side effects (n = 38, 79%). CONCLUSIONS: Contraceptive uptake was significantly lower and method mix different among females with sickle cell disease compared to the general United States population. Further research is needed on contraceptive safety, non-contraceptive benefits, and contraceptive decision-making for females with sickle cell disease. IMPLICATIONS: This study sheds light on the contraceptive choices and preferences of females with sickle cell disease, who are at disproportionate risk for pregnancy complications. In order to maximize the reproductive health of females with sickle cell disease, we must consider how their disease interacts with contraception and better understand how they approach contraceptive decision-making.

RESUMEN

PROBLEM: Decidualized cells display an active role during embryo implantation sensing blastocyst quality, allowing the implantation of normal developed blastocysts and preventing the invasion of impaired developed ones. Here, we characterized the immune microenvironment generated by decidualized cells in response to soluble factors secreted by blastocysts that shape the receptive milieu. METHOD OF STUDY: We used an in vitro model of decidualization based on the Human Endometrial Stromal Cells line (HESC) differentiated with medroxiprogesterone and dibutyryl-cAMP, then treated with human blastocysts-conditioned media (BCM) classified according to their quality. RESULTS: Decidualized cells treated with BCM from impaired developed blastocysts increased IL-1ß production. Next, we evaluated the ability of decidualized cells to modulate other mediators associated with menstruation as chemokines. Decidualized cells responded to stimulation with BCM from impaired developed blastocysts increasing CXCL12 expression and CXCL8 secretion. The modulation of these markers was associated with the recruitment and activation of neutrophils, while regulatory T cells recruitment was restrained. These changes were not observed in the presence of BCM from normal developed blastocysts. CONCLUSION: Soluble factors released by impaired developed blastocysts induce an exacerbated inflammatory response associated with neutrophils recruitment and activation, providing new clues to understand the molecular basis of the embryo-endometrial dialogue.

RESUMEN

OBJECTIVE: This study aims to determine the relationship between estradiol hormone levels and duration of the usage on sexual dysfunction in Depo Medroxy Progesterone Acetate acceptors. METHOD: Family Planning (KB/Keluarga Berencana) Depo Medroxy Progesterone Acetate as many as 43 respondents who meet the sample criteria. The sampling technique used was accidental sampling. Data analysis was performed by using chi square. RESULTS: The results showed that there was a significant relation between levels of the hormone estradiol and the incidence of sexual dysfunction (p=0.000), as well as the length of time using Depo Medroxy Progesterone Acetate on sexual dysfunction (p=0.000). CONCLUSION: The result of data analysis is that the duration of Depo Medroxy Progesterone Acetate injection usage significantly reduces the level of the hormone estradiol which can cause sexual dysfunction in Depo Medroxy Progesterone Acetate acceptors.

RESUMEN

Objective: To compare the clinical outcomes of dydrogesterone (DYG) and medroxyprogesterone (MPA) in the progestin-primed ovarian stimulation (PPOS) protocol for patients with poor ovarian response (POR). Patients and Methods: This was a retrospective cohort study. Women with POR who underwent IVF/ICSI at the Reproductive Center of Third Affiliated Hospital of Zhengzhou University between January 2020 and January 2021 were included. The primary outcome measure of our study was the number of oocytes retrieved. The secondary outcome measures in the present study were the number of 2PN, number of available embryos, oocyte retrieval rate, fertilization rate, viable embryo rate per oocyte retrieved, cancellation rate and pregnancy outcomes of the first embryo transfer cycle, including the biochemical pregnancy, clinical pregnancy and miscarriage rates. Results: In total, 118 women underwent hMG +DYG protocols, and 692 women who underwent hMG +MPA met the Bologna criteria for POR. After baseline characteristics were balanced using the PSM model, 118 hMG +DYG protocols were matched to 118 hMG +MPA protocols, and the baseline characteristics were comparable between the two groups. The numbers of oocytes retrieved, 2PN, and available embryos and the oocyte retrieval rate, fertilization rate, viable embryo rate per oocyte retrieved and cancellation rate of the hMG+DYG and hMG+MPA protocols were comparable. Altogether, 66 women in the hMG+DYG group and 87 women in the hMG+MPA group underwent first embryo transfers. In the hMG+DYG group, 81.8% (54/66) of the patients underwent cleavage embryo transfers; similarly, 79.3% (69/87) of patients in the hMG+MPA group had cleavage embryo transfers (P=0.70).The biochemical pregnancy rate of the hMG+DYG group was 42.4%, and this was comparable to the rate in the hMG+DYG group, at 34.5% (P=0.32). The clinical pregnancy rates were similar between the two groups (36.4% vs. 31.0%, P=0.49), and there was no significant difference in the rate of miscarriage between the two groups (12.5% vs. 29.6%, P=0.14). Conclusion: For women with POR, the clinical outcome of the hMG + DYG group was similar to that of the hMG + MPA group, indicating that both combinations can be useful options for PPOS protocols.
