Predictors of Precancerous Diseases of the Cervix

Introduction. The incidence of malignant neoplasms in the population has increased by 1.66 times over the past 15 years, and the incidence of cancer of the cervix and body of the uterus, placenta — by 1.3 times.Materials and methods. 2 groups were formed by the continuous sampling method: 30 women with a diagnosis of cervical intraepithelial neoplasia (CIN) and 30 women without a diagnosis of CIN, who made up the control group. Statistical analysis was carried out using the StatTech 3.1.7 program (Stattech LLC, Russia).Results. Risk factors for precancerous diseases of the cervix include the presence of a history of cardiovascular diseases(p = 0.043), surgical interventions (p = 0.039), sexually transmitted infections (p = 0.023), a large number of pregnancies (regardless of the outcome) (p = 0.013), the presence of abortions (p = 0.04), a large number of sexual partners during life (p = 0.022).Discussion. Frequent change of sexual partners, and as a consequence — a high risk of STIs are also well-known risk factors for cancer and precancerous cervix, in these conditions HPV passes from free to episomal form faster and starts the process of transformation of cervical epithelial cells.Conclusion. The features of the anamnesis of women with precancerous diseases of the cervix are high parity and the presence of abortions, STIs, cardiovascular diseases and surgical interventions in the anamnesis, a large number of sexual partners in life, low adherence to the use of combined oral contraceptives (COCs).

Differential effect of two hormonal contraceptives on the relative telomere length of youth with type 1 diabetes

Abstract Context Adolescents and young women (AYA) with type 1 diabetes (T1D) may require hormonal contraception for an extended period. However, it is unclear what effect hormonal contraception has on telomere length, a marker of the risk for complications. Objectives To investigate the relative telomere length (RTL) in AYA with T1D (AYA-T1D) and healthy young women (AYA-C) after 18 months of combined oral contraception use (COC) with ethinyl estradiol/desogestrel, or a subdermal etonogestrel implant (IM). Methods A non-randomized prospective study was performed. Thirty-nine AYA-T1D and forty AYA-C chose the COC or the IM. RTL was measured by monochrome multiplex quantitative PCR in DNA from peripheral blood mononuclear cells (PBMC). The impact of contraceptives and clinical variables on RTL was assessed using lineal regression analysis. Results Longer RTL compared to baseline was observed in AYA-T1D (P< 0.05) and AYA-C (P<0 .01) after using the IM. However, the total of AYA and the AYA-C group treated with COC decreased RTL after 18 months of treatment compared to baseline (P< 0.05). The type of contraceptive used was determinant for the changes in RTL compared to baseline in all subjects and controls (P≤ .006). For AYA-T1D, HbA1c levels were not associated with RTL, but the high-sensitivity C-reactive protein was negatively related with the changes in RTL at eighteen months compared to baseline (standardized R2: .230, P=.003). Conclusion IM was associated with longer RTL in AYA-T1D and AYA-C. In contrast, a shortening of telomere length in PMNC was observed after using COC.

Abstract 2195: Intrauterine device use and risk of invasive epithelial ovarian cancer: A population-based case-control study

Abstract Introduction: Ovarian, fallopian tube, and primary peritoneal cancers (hereafter referred to as ovarian cancer) are the most fatal gynecologic cancers. Thus, it is imperative to identify strategies that can reduce the risk of the disease. Several contraceptive methods have been shown to be associated with a reduced risk of ovarian cancer, including combined oral contraceptives, injectable progestins, and tubal ligation. However, the use of these contraceptive methods has been decreasing in the U.S., with a growing preference for intrauterine devices (IUDs) for pregnancy prevention. Previous case-control studies on the association between IUD use and ovarian cancer risk have found inconsistent results. Notably, previous studies had small sample sizes and did not restrict to invasive epithelial tumors. The current analysis assessed the association between IUD use and risk of invasive epithelial ovarian cancer in a large population-based case-control study. Methods: This analysis used data from 1,713 people diagnosed with primary invasive epithelial ovarian cancer (cases) and 2,348 cancer-free people (controls) participating in a case-control study conducted in Los Angeles, CA from 1992-2010. The study consisted of four waves of recruitment with similar enrollment and data collection methods. Logistic regression models were fit to assess the association between IUD use and risk of invasive epithelial ovarian cancer. All models were adjusted for age, race/ethnicity, education, first-degree family history of ovarian cancer, endometriosis, body mass index, duration of combined oral contraceptive use, parity, duration of breastfeeding, tubal ligation, and study wave. Heterogeneity across the study waves and the ovarian cancer histotypes was evaluated using standard meta-analysis techniques. Results: There was no statistically significant association between IUD use and risk of invasive epithelial ovarian cancer (odds ratio=1.09, 95% confidence interval 0.93-1.28). This result was consistent across the study waves and the ovarian cancer histotypes (p-values for heterogeneity>0.05). Conclusion: IUD use was not associated with the risk of invasive epithelial ovarian cancer. Analysis by IUD type (i.e., hormone-releasing vs copper IUDs) was not possible in this study as these data were not collected. Future research should examine whether the type of IUD (i.e. copper versus hormone-releasing) may have different effects on risk of ovarian cancer.

Combined estrogen-progestin oral contraceptives and female sexuality: an updated review.

Sexual side effects of combined oral contraceptives (COCs) have not been fully understood, but increasing evidence prompts broader risk/benefit evaluation and merits inclusion in counseling on contraceptive options. The study sought to explore the impact of combined estrogens-progestin oral contraceptives on components of female sexuality, including sexual desire, anatomic genitourinary changes, lubrication, orgasm, provoked vestibulodynia, well-being, body image, partner preference, and relationship stability. A literature review was performed between April 2023 and January 2024 exploring the association between combined oral contraceptive pills and sexual health. Although COCs decrease free testosterone, it is unclear if COCs affect sexual function, including desire. Antiandrogenic COCs do seem to have a negative effect on sexual arousal, lubrication, and orgasm. Provoked vestibulodynia may be related to early onset of COC use, low-estrogen pills, and antiandrogenic progestins. Emotional and sexual side effects are strong predictors of COC discontinuation. Longitudinal data indicate that using COCs when meeting and selecting a partner has implications on sexual satisfaction and relationship length. Analysis of data is complicated by various doses and forms of estrogen and progestin in COCs, which have changed over time. Lack of randomized placebo-controlled studies and heterogenicity in study design hampers generalized statements about the effects of COCs on sexual function. Despite these challenges, consideration of sexual dysfunction when presenting and prescribing hormonal contraception is essential for informed consent, shared decision making, and ensuring reliable contraceptive choices.

Effect on Endoplasmic Reticulum Stress of the Combined Oral Contraceptives in the Liver

Objective: We aimed to evaluate the effects of combined oral contraceptive active ingredients ethinylestradiol, drospirenone, and ethinylestradiol+drospirenone for histopathological changes, and endoplasmic reticulum stress levels in the liver.
 
 Methods: In the study, 37 to 8-week-old Balb/c female mice were used. Mice were randomly divided into the control, sham, ethinylestradiol, drospirenone, and ethinylestradiol+drospirenone groups. Experimental groups were administered ethinylestradiol, drospirenone, and ethinylestradiol+drospirenone with gavage for 35 days. In liver tissue sections, histopathological changes were detected with hematoxylin&eosin, orcein, Mallory's Azan, and periodic acid-Schiff, and the presence of endoplasmic reticulum stress was detected by Chop and Grp78 immunostaining.
 
 Results: The ethinylestradiol+drospirenone group showed significant histopathological changes compared to the control group. Some degenerative changes were noted such as swelling and size differences in hepatocytes in the ethinylestradiol+drospirenone group. When compared to the control group, an increased collagen and elastic fibers density around the vena centralis was observed in the ethinylestradiol+drospirenone group. The expression level of Grp78 protein in female mice given ethinylestradiol+drospirenone was statistically significantly increased compared to the control group. The expression level of Chop protein was significantly increased in the ethinylestradiol, drospirenone, and ethinylestradiol+drospirenone groups. 
 
 Conclusion: We concluded that the use of combined oral contraceptives increases endoplasmic reticulum stress in mouse liver tissue, and as a result, it may cause liver histopathological disorders by promoting cell death.

The effect of lavender on mood disorders associated with the use of combined oral contraceptives (COCs): a triple-blinded randomized controlled trial

BackgroundThe use of contraceptive methods is influenced by their effectiveness, availability, and minimal side effects. OCPs are one of the most effective and widely used methods of pregnancy prevention worldwide. This method not only prevents pregnancy but also helps prevent and treat other diseases. One of the main reasons for discontinuing this method is the emotional disturbances associated with its use. Lavender is an evergreen, fragrant plant that has gained significant attention for its anti-anxiety effects. This study was conducted to investigate the effect of lavender essential oil capsules on mood disorders during the use of COCs.MethodsThis triple-blinded clinical trial was conducted on 60 married women (aged 15–49 years old) who were consumers of COCs, referring to 26 health centers in Tabriz, Iran. The participants were randomly assigned to either the intervention (consuming one gelatin capsule containing 80 mg LEO daily) or control (consuming one placebo capsule daily) group. The intervention continued for 56 days. Scores for positive and negative were determined using the Positive and Negative Affect Schedule (PANAS) questionnaire; and for stress, depression, and anxiety were measured using the DASS-21 questionnaire on day’s 28th and 56th post-intervention. Data analysis was conducted using the t-test and ANOVA with repeated measures, and a p-value of < 0.05 was considered significant for all analyses.ResultsA statistically significant difference was observed in mood disorders, stress, and depression between women receiving LEO or placebo. The consumption of LEO increased the positive mood on day 28 [MD (95% CI): 4.5 (2.1 to 7.0), p = 0.001] and day 56 [5.9 (3.4 to 8.3), p < 0.001] while decreased the negative mood on day 28 [MD (95% CI): -3.5 (-5.3 to -1.3), p < 0.001] and day 56 [-4.3 (-6.3 to -2.2), p < 0.001], stress on day 28 [MD (95% CI): -4.9 (-7.1 to -2.8), p = 0.001] and day 56 [-5.3 (-7.6 to -3.1), p < 0. 001], and depression on day 28 [MD (95% CI): -3.0 (-4.9 to 1.1), p = 0.003] and day 56 [-3.1 (-5.0 to 1.2), p = 0.002]. There was no statistically significant difference between the two groups in terms of anxiety.ConclusionsThe consumption of LEO with COCs improved mood disorders and reduced stress and depression. The use of hormonal contraceptives and mood changes should be considered by providers. Therefore, regarding the possibility of mood changes, it is expected that appropriate counseling and education will be provided to women who consume COC., providing appropriate solutions, including the simultaneous use of LEO.

Combined Oral Contraceptives: Association with Serum 25-Hydroxyvitamin D and Calcium and Bone Homeostasis.

Background: Use of combined oral contraceptives (COCs) has been found to increase serum 25-hydroxyvitamin D [25(OH)D] but effects on calcium and bone homeostasis are unclear. Materials and Methods: Serum 25(OH)D, parathyroid hormone (PTH), alkaline phosphatase (ALK) and estradiol, dietary intake of bone-related nutrients and foods, bone mineral density (BMD), and body fat were compared in adult women (20-35 years; body mass index 21.5 ± 2.3 kg/m2) users (+COC, n = 32) and nonusers (-COC, n = 20) of COC. Biochemical markers were measured by automated assays. BMD at total body (TB), lumbar spine (LS), femoral neck (FN) and trochanter (TR), and body fat, were measured by dual-energy X-ray absorptiometry. Dietary intake was assessed by a food frequency questionnaire. Results: Intake of calcium, dairy foods, and fruits and vegetables, were adequate and did not differ by COC. Mean 25(OH)D was 35% higher in +COC (110.4 ± 27.3 nmol/L, 44.2 ± 1.8 ng/mL) compared with -COC (81.7 ± 22.8 nmol/L, 32.7 ± 2.3 ng/mL; p < 0.001). Mean PTH, ALK, and estradiol were 28%, 12%, and 62% lower, respectively, in +COC compared with -COC (p ≤ 0.05). Mean BMD z-scores (all sites) were adequate and did not differ by COC. There were no correlations between 25(OH)D and dietary, biochemical, and body composition variables. PTH was inversely correlated with TR-BMD z-score in -COC (r = -0.47; p = 0.04), and ALK was inversely correlated with TB-, TR-, and LS-BMD z-scores in -COC (r ≤ -0.43; p ≤ 0.04), but not in +COC. Conclusions: Increased serum 25(OH)D with COC use was paralleled by expected physiologic adjustments in calcium and bone homeostasis, and adequate bone mass status, in nonobese young adult women consuming bone-healthy diets.

Effect of combined oral contraceptive on cardiorespiratory function and immune activation in premenopausal women involved in exercise: A systematic review protocol.

The use of combined oral contraceptive (COC) is common among women of reproductive age despite the potential risk of them developing thrombotic events. There is a need to understand how COC affects cardiorespiratory function and markers of immune activation in premenopausal women involved in exercise. This highlights a need for a systematic review to enhance our understanding of how the use of COC affects cardiovascular health in premenopausal women subjected to exercise. This systematic review protocol was prepared following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) 2015 statement. An extensive search of relevant literature by two independent reviewers will be conducted through the EBSCOhost interface to access databases such as MEDLINE, EMBASE, and CINAHL. Other health sources, including Cochrane CENTRAL, unpublished studies and grey literature, will also be searched. The search will include all studies that report the effect of COC on essential parameters of cardiorespiratory function and markers of immune activation in premenopausal women involved in exercise. All included studies will be appraised using appraisal tools, while appropriate extraction tools will be used for data extraction. Where possible, eligible studies will be pooled for meta-analysis. If statistical pooling is not feasible, our findings will be presented in a narrative format. The certainty of evidence will be assessed using the Grading of Recommendations, Assessment, Development and Evaluation Assessment (GRADE) tool. PROSPERO registration number: CRD42021265257.

Continuous combined oral contraceptive use versus vitamin E in the treatment of menstrual migraine: rationale and protocol of a randomized controlled trial (WHAT!)

BackgroundCurrently, there is no evidence-based hormonal treatment for migraine in women. Several small studies suggest a beneficial effect of combined oral contraceptives, but no large randomized controlled trial has been performed. As proof of efficacy is lacking and usage may be accompanied by potentially severe side effects, there is a great need for clarity on this topic.MethodsWomen with menstrual migraine (n = 180) are randomly assigned (1:1) to ethinylestradiol/levonorgestrel 30/150 μg or vitamin E 400 IU. Participants start with a baseline period of 4 weeks, which is followed by a 12-week treatment period. During the study period, a E-headache diary will be used, which is time-locked and includes an automated algorithm differentiating headache and migraine days.ResultsThe primary outcome will be change in monthly migraine days (MMD) from baseline (weeks − 4 to 0) to the last 4 weeks of treatment (weeks 9 to 12). Secondary outcomes will be change in monthly headache days (MHD) and 50% responder rates of MMD and MHD.ConclusionsThe WHAT! trial aims to investigate effectivity and safety of continuous combined oral contraceptive treatment for menstrual migraine. Immediate implementation of results in clinical practice is possible.Trial registrationClinical trials.gov NCT04007874. Registered 28 June 2019.

USE OF COMBINED ORAL CONTRACEPTIVES AND THE RISK OF CERVICAL CANCER IN YOUNG WOMEN

The relationship between the use of combined oral contraceptives and the risk of cervical cancer in young women has been the subject of intense scrutiny in the scientific literature. This topic, which is extremely important for women's health, has sparked debates and investigations due to the prevalence of the use of these contraceptives and the significant incidence of cervical cancer in young women. Understanding this possible association is crucial to inform contraceptive practices and cervical cancer prevention strategies. Objective: To evaluate and consolidate the available evidence on the relationship between the use of combined oral contraceptives and the risk of cervical cancer in young women, using studies and articles published in the last 10 years. Methodology: strictly adhered to the PRISMA checklist, using the PubMed, Scielo and Web of Science databases to identify relevant studies. The selected descriptors were combined oral contraceptives, cervical cancer, young women, risk and association. The search covered articles published in the last 10 years. The inclusion criteria included studies that focused exclusively on young women, directly investigated the relationship between the use of combined oral contraceptives and cervical cancer, and were published in the last 10 years. On the other hand, studies with participants outside the specific age range, research that did not directly address the association in question and articles that were not fully available or did not qualify as systematic reviews or primary studies were excluded. This methodological approach provided a comprehensive and careful analysis of the existing evidence on the topic. Results: 18 articles were selected. Analysis of studies revealed a diversity of perspectives on the association between combined oral contraceptives and cervical cancer risk in young women. Key topics included possible biological mechanisms, variations in the types of contraceptives used, and the influence of confounding factors. Conclusion: Given the complexity of the data analyzed, this review highlights the need for careful approaches in interpreting the relationship between combined oral contraceptives and cervical cancer in young women. Future research is crucial to fully clarify this association and provide more precise guidance for clinical practice.

Target groups of young women for triphasic combined hormonal contraception

Hormonal contraception is widely used to prevent unintended pregnancies and is represented by a large number of drugs that allow to personalize the choice of contraceptives for each woman. Combined oral contraceptive (COC) variants include not only drugs that differ in qualitative composition, but also modifications of the dosage regimen. Among the non-trivial regimens are triphasic active ingredient dosing that enables to achieve a reduction in progestogen burden while maintaining contraceptive efficacy. This approach is important in prescribing COCs to women who have previously experienced or may potentially experience adverse reactions to progestogens. Identification of target groups of women predisposed to progestogen-dependent side effects helps to correctly prescribe COCs and improve adherence to the contraceptive method. Thus, changes in bleeding characteristics during the use of hormonal contraceptives may lead to refusal of COCs. With the exception of patients who are prescribed COCs for additional therapeutic purposes to control the menstrual cycle rhythmicity and intensity, women expect that they keep the usual pattern of their cycle and react negatively to any changes or deviations from the reference ranges. Meanwhile, the bleeding profile during the use of hormonal contraceptives can change significantly. Characteristics such as the intensity and predictability of uterine bleeding are important for the assessment of the effect of a contraceptive on uterine bleeding. This analytical review presents groups of young women for whom initial use of triphasic COCs may be the best choice.

Management of Premenstrual Dysphoric Disorder: A Scoping Review.

Premenstrual dysphoric disorder (PMDD) and premenstrual syndrome (PMS) refer to physical, cognitive, or affective symptoms that arise in the late luteal phase and remit with menses. The present work is a clinically focused scoping review of the last twenty years of research on treatment for these disorders. A search of key terms using the PubMed/Medline, the Cochrane Library, Embase, and Web of Science databases was performed, and 194 studies of adult women met initial inclusion criteria for review. Research studies concerning medications, pharmacological and non-pharmacological complementary and alternative medicine treatments, and surgical interventions with the most available evidence were appraised and summarized. The most high-quality evidence can be found for the use of selective serotonin reuptake inhibitors (SSRIs) and combined oral contraceptives (COCs), with gonadotropin releasing hormone (GnRH) agonists and surgical interventions showing efficacy for refractory cases. While there is some evidence of the efficacy of alternative and complementary medicine treatments such as nutraceuticals, acupuncture, and yoga, variability in quality and methods of studies must be taken into account.

Влияние дроспиренонсодержащего контрацептива на состояние кожи у женщин с регулярным менструальным циклом

Background: combined oral contraceptives (COCs) are one of the most popular methods of contraception. Apart from pregnancy prevention, it has proven other positive non-contraceptive effects. However, there are cases of acne vulgaris (AV) manifestation during COCs intake or its course worsens, which can lead to treatment refusing. Aim: to study the COCs effect (20 μg ethinyl estradiol (EE) and 3 mg drospirenone (DRSP)) on the skin condition of young women with a regular menstrual period. Patients and Methods: a prospective study was performed, which included 18 female patients of reproductive age (mean age 20.67±0.46 y.o.) with a regular menstrual period who sought medical advice to select a contraceptive. Of these, 11 had mild to moderate AV manifestations. The female patients were recommended to take DRSP-containing COConce daily before bedtime from the 1st day of the menstrual period for 28 straight days (1 period) — a total of 6 periods. Before the treatment initiation, as well as 3 and 6 months after the COCs intake start, the skin condition and indicators of the Acne-specific Quality of Life Questionnaire (Acne-QoL) of female patients with AV were evaluated. Results: the number of female patients without AV or with improvement after 3 and 6 months of treatment was 12 (66.67%) and 18 (100%), respectively. Compared with the baseline, there was a statistically significant decrease in Acne-QoL from 68 (63-80) to 40 (36-50) and 5 (10- 17) after 3 and 6 months, respectively (p&lt;0.05). The good tolerability of DRSP-containing COC was also noted. Adverse events that were independently eliminated and did not require drug withdrawal were recorded in two (11.1%) cases. Conclusion: the use of DRSP-containing COC (20 μg EE and 3 mg DRSP) in women with a regular menstrual period improves skin condition (reduces the amount and severity of AV) and reduces Acne-QoL.

Is the multinational, surveillance PRO-E2 study informative for all countries? The Italian data on VTE and contraceptive effectiveness

Purpose To evaluate whether the thromboembolic risk and contraceptive effectiveness of NOMAC-E2 observed in the PRO-E2 study can be extended to each participating country, as lifestyle, cardiovascular risk factors and prescribing habits may differ geographically. This analysis was performed on the PRO-E2 Italian subpopulation, where smoking habit and women over 35 years were more prevalent compared with the overall study population. Materials and methods Data from NOMAC-E2 or levonorgestrel-containing COCs (COCLNG) new users were descriptively analysed. Incidence rates of thrombosis (events/10,000 women-years [WY]) and the Pearl Index (pregnancies/100 WY) were calculated. Results Overall, 11,179 NOMAC-E2 and 8,504 COCLNG users were followed up to 2 years (34,869 WY). The NOMAC-E2 cohort included more women over 35 vs. COCLNG (37.7% vs. 31.8%; p = 0.001). A comparable low risk of combined deep venous thrombosis of lower extremities (DVT) and pulmonary embolism (PE) was observed in NOMAC-E2 (1.7/10,000 WY; 95% CI: 0.21–6.2) and COCLNG users (6.6/10,000 WY; 95% CI: 2.4–14.4). Similar results were obtained by considering all thromboembolic events (VTE). Unintended pregnancies did not differ between NOMAC-E2 (0.12/100 WY; 95% CI: 0.06–0.21) and COCLNG (0.15/100 WY; 95% CI: 0.08–0.26) cohorts. Conclusion Despite the higher age and tobacco use, findings from the Italian subpopulation were broadly consistent with overall PRO-E2 results, confirming a similar low thromboembolic risk and high contraceptive effectiveness of NOMAC-E2 and COCLNG. Short condensation This subgroup analysis of the PRO-E2 study provides comprehensive epidemiological data on the use of combined oral contraceptives in a large Italian cohort, with a higher prevalence of women over 35 years and smokers. The study confirms the low thromboembolic risk and high contraceptive effectiveness of NOMAC-E2 pill.

The role of sex hormones, oral contraceptive use, and its parameters on visuospatial abilities, verbal fluency, and verbal memory

Sex hormones can cross the blood-brain barrier and access brain regions underlying higher-order cognition. Containing synthetic sex hormones, oral contraceptives (OC) have been found to modulate visuospatial and verbal abilities, though inconsistencies have been found in the literature. Among possible explanations, certain OC use parameters (progestin androgenicity, synthetic hormone levels, duration of use) have not received consistent consideration. Thus, the objectives were to (1) examine group differences between men, combined OC users, and naturally cycling women (NC women; not using OC) in visuospatial abilities, verbal fluency, and verbal memory and (2) investigate the contribution of endogenous and exogenous sex hormones on these effects. We also aimed to (3) identify OC use parameters relevant to cognitive outcomes. In total, 70 combined OC users, 53 early follicular (EF) women, 43 pre-ovulatory (PO) women, and 47 men underwent cognitive tests. Performance was compared based on hormonal milieus (OC, EF, PO, men) and OC users' contraceptive androgenicity (anti, low, high). Correlations between performance, hormone levels and OC use duration were also conducted. OC use dampened the sex difference that typically favors men in 3D visuospatial abilities, whereas its duration of use positively predicted verbal fluency. Androgenicity and hormone levels did not predict performance in any task. These results highlight the importance of considering OC use duration. Results also did not support a role for androgenicity in cognition. Importantly, combined OC use (including prolonged use) does not impair visuospatial, verbal, and memory functions in a healthy young sample.

Abstract 13091: Chronic Thromboembolic Pulmonary Hypertension Associated With Prolonged Use of Combined Oral Contraceptives in a 27-Year-Old Woman: A Successful Case of Pulmonary Endarterectomy

Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH) is associated with venous thromboembolism (VTE); however, in half of the cases, no prior deep vein thrombosis is ever found. The use of combined oral contraceptives (COCs) is a known risk factor for VTE. We present the case of a young woman with CTEPH in whom timely diagnosis and intervention prevented irreversible pulmonary hypertension (PH). Case Presentation: A 27-year-old woman with 10-year use of COCs presented with progressive dyspnea for 3 weeks. The ECG showed right ventricular systolic overload and right atrial enlargement. Laboratory tests showed elevated pro-BNP and D-dimer. TTE showed right atrium and right ventricle (RV) enlargement and elevated right ventricular systolic pressure (RVSP) of 83 mmHg. The ventilation/perfusion scintigraphy showed mismatched segmental perfusion defects in both lung fields with greater involvement of the left lung, and oral anticoagulation was started. Lower extremity venous ultrasound and hypercoagulability studies were normal. CTPA revealed filling defects in the left main pulmonary artery and bilateral segmental branches. After 3 months of anticoagulation, she persisted in NYHA class III, and right heart catheterization showed mean PAP of 38 mmHg, PCWP of 8 mmHg, and PVR of 9 WU, confirming CTEPH. Due to unavailability in Peru, she was referred to a US center for pulmonary endarterectomy (PEA). After a successful intervention, she improved clinically with a reduction in RVSP to 34 mmHg. This case highlights the importance of rapid intervention in CTEPH even in situations where optimal treatment is not readily available. Conclusion: CTEPH may be associated with the prolonged use of COCs in young women. Timely intervention can reverse PH and prevent RV remodeling. Unfortunately, Peru does not have a PEA center and not every case will undergo treatment. We call for the training of local surgeons to ensure fair and equitable access for the population.

An Endocrine Perspective on Lynch Syndrome

"Background: A germline mutation of the MisMatch Repairgene that causes a malfunctioning DNA system is the defining feature of the hereditary illness known as Lynch syndrome. This review will discuss the endocrine aspects of LS and highlight current advancements in the area. Methods: We searched the available literature of the last 10 years for terms such as endocrine tumors and LS. Our goal is to provide a summary of the most recent information available on the endocrine perspective in Lynch syndrome. Results: The hormonal chemoprevention methods cited are the use of combined oral contraceptives, the use of progestogen-releasing intrauterine devices, and the use of progesterone-only drugs. In addition, after surgical exclusion of the uterus and ovaries, a method frequently adopted for LS patients, it is necessary to start hormonal menopausal therapy, taking into account certain age-specific features. In addition, numerous LS-associated endocrine tumor types have been described. Conclusions: Many hormonal variants are available that are useful in the chemoprevention involved in the treatment of LS. Menopausal hormone therapy is imperative for LS patients who need it. Clinicians need to be aware of the possible association of certain types of aggressive endocrine cancers associated with LS."

Mental Health Symptoms in Oral Contraceptive Users During Short-Term Hormone Withdrawal

Hormonal contraception has been linked to mood symptoms and the ability to recognize emotions after short periods of treatment, whereas the mental health of users of long-term hormonal contraceptives has had limited investigation. To evaluate whether short-term hormonal withdrawal, which users of combined oral contraceptives (COCs) undergo once a month (pill pause), was associated with altered mood and emotional recognition in long-term users of COCs. This case-control study included a community sample of individuals assigned female sex at birth who identified as women and used COC for 6 months or longer. The control group included women with natural menstrual cycles who otherwise fulfilled the same inclusion criteria. The study was conducted between April 2021 and June 2022 in Salzburg, Austria. COC users and women with natural menstrual cycles were tested twice within a month, once during their active pill phase or luteal phase and once during their pill pause or menses. Negative affect, anxiety, and mental health problems were assessed during each session. The percentage increase in mental health symptoms was calculated during the pill pause compared with that during the active intake phase in COC users. How this change compared with mood fluctuations along the menstrual cycle in women with natural menstrual cycles was assessed. A total of 181 women aged 18 to 35 years (mean [SD] age, 22.7 [3.5] years) were included in the analysis (61 women with androgenic COC use, 59 with antiandrogenic COC use, 60 women with a menstrual cycle not taking COCs). COC users showed a 12.67% increase in negative affect (95% CI, 6.94%-18.39%), 7.42% increase in anxiety (95% CI, 3.43%-11.40%), and 23.61% increase in mental health symptoms (95% CI, 16.49%-30.73%; P < .001) during the pill pause compared with the active intake phase. The effect size of this change did not differ depending on progestin type (negative affect: F1,117 = 0.30, P = .59; state anxiety: F1,117 = 2.15, P = .15; mental health: F1,117 = .16, P = .69) or ethinylestradiol dose (negative affect: F1,57 = .99, P = .32; state anxiety: F1,57 = 2.30, P = .13; mental health: F1,57 = .14, P = .71) was comparable with mood changes along the menstrual cycle in women with natural cycles (negative affect: F2,175 = 0.13, P = .87; state anxiety: F2,175 = 0.14, P = .32; mental health: F2,175 = 0.65, P = .52). Mood worsening during the pill pause was more pronounced in women with higher baseline depression scores (negative affect increase of 17.95% [95% CI, 7.80%-28.10%] in COC users with higher trait depression [BDI >8]). Emotion recognition performance did not differ between active pill phase and pill pause. In this case-control study of long-term COC users, withdrawal from contraceptive steroids during the pill pause was associated with adverse mental health symptoms similar to those experienced by women during menses with withdrawal from endogenous steroids. These results question the use of the pill pause from a mental health perspective. Long-term COC users may benefit more from the mood-stabilizing effects of COCs in cases of continuous intake.

Hormonal Pretreatment for Ovarian Stimulation: A Narrative Review

Introduction: Assisted reproductive technologies are necessary and important for the management of infertility and can be applied with and without the use of strategies such as hormonal pretreatment. However, there is a discussion in the literature on whether hormonal pretreatment in ovarian stimulation protocols can improve the outcome of oocytes and embryos. This study aimed to conduct an integrative review of hormonal pretreatment and its impact on women undergoing assisted reproduction procedures. Methods: We made searches in the PubMed and the Cochrane Library databases. The inclusion criteria were articles published in peer-reviewed journals in English, Portuguese, or Spanish from January 1, 2010 to December 31, 2021 and available as free full texts. We excluded gray literature works, including term papers, theses, and dissertations. We used a narrative synthesis for data analysis. Results: The 189 articles retrieved from the two databases (2010-2021) were narrowed down to eight articles. In most studies, pretreatment seems to play a role beyond stimulation that includes an early inhibition of the FSH peak, a more homogeneous cohort, and better results. Conclusions: Using a pretreatment with combined oral contraceptives (COC) produces conflicting results in assisted reproduction. The COC improves the quantity and quality of eggs, but it neither benefits nor harms reproductive outcomes. Also, the use of COC has contradictory results regarding clinical pregnancy
