Detection of peritoneal, ovarian, and bowel endometriosis using FTIR spectroscopy and machine learning

Olcha P et al., 2026 Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy

This study evaluated the diagnostic potential of Fourier-transform infrared (FTIR) spectroscopy combined with machine learning for the detection of ovarian, bowel, and peritoneal endometriosis. The Boruta algorithm was applied to identify the most informative spectral intervals for each endometriosis type, revealing characteristic wave number ranges associated with molecular changes in endometriotic tissue. For ovarian endometriosis, key intervals included 741-748 cm-1, 984-993 cm-1, and 1125-1132 cm-1 bowel endometriosis, 1055-1063 cm-1, 1077-1079 cm-1, 1561-1572 cm-1, and 1717-1720 cm-1, and for peritoneal endometriosis, 917-919 cm-1, 1542-1547 cm-1, and 1573-1576 cm-1. Three machine learning algorithms, Deep Learning (DL), Support Vector Machine (SVM), and XGBoost, were tested using both the full spectral range and the Boruta-selected feature subsets. Across all endometriosis types, XGBoost consistently outperformed DL and SVM. Using the full spectrum, XGBoost achieved accuracies of 0.81, 0.77, and 0.78 for ovarian, bowel, and peritoneal endometriosis, respectively. Feature selection with Boruta significantly improved performance, increasing accuracies to 0.93, 0.88, and 0.90, respectively, and enhancing sensitivity, specificity, precision, F1 score, MCC, and ROC AUC across all datasets. DL models often exhibited high sensitivity but poor specificity, while SVM performance improved moderately with feature selection. Overall, these results demonstrate that targeted spectral feature selection enhances the diagnostic accuracy of machine learning models for endometriosis. XGBoost, in combination with Boruta-selected spectral intervals, provides the most reliable and balanced predictions, highlighting its potential for non-invasive detection and differentiation of ovarian, bowel, and peritoneal endometriotic lesions.

Effects of topical dehydroepiandrosterone therapy in women after pelvic organ prolapse surgery

Nowakowski Ł et al., 2023 Menopause (New York, N.Y.)

Pelvic organ prolapse (POP) occurs predominantly in postmenopausal women. Restoration of the proper estrogenization of vaginal mucosa is important in preoperative and postoperative treatment, increasing the effectiveness of this approach. The objective of this study was the development of intravaginal vaginal suppositories containing DHEA and comparison of the clinical effects of vaginal topical therapy with DHEA, estradiol, or antibiotic after POP surgery. Nine types of vaginal suppositories containing 6.5 mg DHEA in different bases were prepared to find optimal formulation for the vaginal conditions. Ninety women referred for POP surgery were randomly assigned to one of three groups receiving topical treatment in the postoperative period (estradiol, DHEA, or antibiotic). On admission to hospital and during follow-up vaginal pH, vaginal maturation index and vaginal symptoms were assessed. Vaginal suppositories with the base made from polyethylene glycol 1,000 without surfactants characterized the highest percentage of the released DHEA. In women treated with topical estradiol or DHEA a significant decrease in the number of parabasal cells, increase in superficial and intermediate cells in the vaginal smears, decrease in vaginal pH, and reduction of vaginal symptoms were observed. The use of topical therapy with DHEA or the use of topical therapy with estradiol in the postoperative period were both shown to improve maturation index, vaginal pH, and vaginal symptoms. The benefits of topical therapy with DHEA after pelvic organ prolapse repair brings similar results as estradiol, without potential systemic exposure to increased concentrations of sex steroids above levels observed in postmenopausal women.

International Natural Procreative Technology Evaluation and Surveillance of Treatment for Subfertility (iNEST): enrollment and methods

Stanford JB et al., 2022 Hum Reprod Open Free full text on PubMed Central

What is the feasibility of a prospective protocol to follow subfertile couples being treated with natural procreative technology for up to 3 years at multiple clinical sites? Overall, clinical sites had missing data for about one-third of participants, the proportion of participants responding to follow-up questionnaires during time periods when participant compensation was available (about two-thirds) was double that of time periods when participant compensation was not available (about one-third) and follow-up information was most complete for pregnancies and births (obtained from both clinics and participants). Several retrospective single-clinic studies from Canada, Ireland and the USA, with subfertile couples receiving restorative reproductive medicine, mostly natural procreative technology, have reported adjusted cumulative live birth rates ranging from 29% to 66%, for treatment for up to 2 years, with a mean women's age of about 35 years. The international Natural Procreative Technology Evaluation and Surveillance of Treatment for Subfertility (iNEST) was designed as a multicenter, prospective cohort study, to enroll subfertile couples seeking treatment for live birth, assess baseline characteristics and follow them up for up to 3 years to report diagnoses, treatments and outcomes of pregnancy and live birth. In addition to obtaining data from medical record abstraction, we sent follow-up questionnaires to participants (both women and men) to obtain information about treatments and pregnancy outcomes, including whether they obtained treatment elsewhere. The study was conducted from 2006 to 2016, with a total of 10 clinics participating for at least some of the study period across four countries (Canada, Poland, UK and USA). The 834 participants were subfertile couples with the woman's age 18 years or more, not pregnant and seeking a live birth, with at least one clinic visit. Couples with known absolute infertility were excluded (i.e. bilateral tubal blockage, azoospermia). Most women were trained to use a standardized protocol for daily vulvar observation, description and recording of cervical mucus and vaginal bleeding (the Creighton Model FertilityCare System). Couples received medical and sometimes surgical evaluation and treatments aimed to restore and optimize female and male reproductive function, to facilitate in vivo conception. MAIN The mean age of women starting treatment was 34.0 years; among those with additional demographic data, 382/478 (80%) had 16 or more years of education, and 199/659 (30%) had a prior live birth. Across 10 clinical sites in four countries (mostly private clinical practices) with family physicians or obstetrician-gynecologists, data about clinic visits were submitted for 60% of participants, and diagnostic data for 77%. For data obtained directly from the couple, 59% of couples had at least one follow-up questionnaire, and the proportion of women and men responding to fill out the follow-up questionnaires was 69% and 67%, respectively, when participant financial compensation was available, compared to 38% and 33% when compensation was not available. Among all couples, 57% had at least one pregnancy and 44% at least one live birth during the follow-up time period, based on data obtained from clinic and/or participant questionnaires. All sites reported on female pelvic surgical procedures, and among all participants, 22% of females underwent a pelvic diagnostic and/or therapeutic procedure, predominantly laparoscopy and hysterosalpingography. Among the 643 (77%) of participants with diagnostic information, ovulation-related disorders were diagnosed in 87%, endometriosis in 31%, nutritional disorders in 47% and abnormalities of semen analysis in 24%. The mean number of diagnoses per couple was 4.7. LIMITATIONS The level of missing data was higher than anticipated, which limits both generalizability and the ability to study different components of treatment and prognosis. Loss to follow-up may also be differential and introduce bias for outcomes. Most of the participating clinicians were not surgeons, which limits the opportunity to study the impact of surgical interventions. Participants were geographically dispersed but relatively homogeneous with regard to socioeconomic status, which may limit the generalizability of current and future findings. Multicenter studies are key to understanding the outcomes of subfertility treatments beyond IVF or IUI in broader populations, and the association of different prognostic factors with outcomes. We anticipate that the iNEST study will provide insight for clinical and treatment factors associated with outcomes of pregnancy and live birth, with appropriate attention to potential biases (including adjustment for potential confounders, multiple imputation for missing data, sensitivity analysis and inverse probability weighting for potential differential loss to follow-up, and assessments for clinical site heterogeneity). Future studies will need to either have: adequate funding to compensate clinics and participants for robust data collection, including targeted randomized trials; or a scaled-down, registry-based approach with targeted data points, similar to the multiple national and regional ART registries. Funding for the study came from the International Institute for Restorative Reproductive Medicine, the University of Utah, Department of Family and Preventive Medicine, Health Studies Fund, the Primary Children's Medical Foundation, the Mary Cross Tippmann Foundation, the Atlas Foundation, the St. Augustine Foundation and the Women's Reproductive Health Foundation. The authors declare no competing interests. The iNEST study is registered at clinicaltrials.gov, NCT01363596.

Cancer and Fertility · Fertility Preservation Before Treatment

Fertility-Sparing Methods in Adolescents Affected by Endometrial Cancer: A Comprehensive Review

Gałczyński K et al., 2021 Journal of clinical medicine Free full text on PubMed Central

Although in developed countries endometrial cancer (EC) is the most common gynecological malignancy, its occurrence in adolescents is exceedingly rare. The increasing rate of obesity in children and adolescents is held responsible for the increasing prevalence of EC in younger cohorts of patients. The diagnosis of this malignancy can have devastating consequences for future fertility because standard treatment protocols for EC include hysterectomy. Here, we present the first detailed review of the world literature on EC in subjects aged 21 years or younger (n = 19). The mean age at diagnosis was 16.7 ± 0.6 years. One patient (5.3%) had a Type II (high-risk) disease. No communication retrieved from the search reported on patient death; however, two (10.5%) patients were lost to follow-up. There was also a high proportion (five subjects, or 26.3%) of cases with genetic background (Cowden syndrome and Turner syndrome), therefore genetic screening or a direct genetic study should be considered in very young patients with EC. The current fertility-sparing options, limited to Type I (low-risk) disease, are presented and discussed. Such information, obtained from studies on older women, translates well to adolescent girls and very young women. Careful anatomopathological monitoring at follow-up is essential for the safety of a conservative approach. Improved survival in very young EC patients makes the preservation of fertility a central survivorship issue, therefore both patients and caregivers should undergo counseling regarding available options. Moreover, our study suggests that genetic syndromes other than Lynch syndrome may be associated with EC more frequently than previously thought.

Ovarian endometrioma - a possible finding in adolescent girls and young women: a mini-review

Gałczyński K et al., 2019 Journal of ovarian research Free full text on PubMed Central

Young girls before menarche or menstruating adolescent women may experience long-term drug-resistant chronic pelvic pain, as well as other symptoms associated with pelvic mass. In such cases, it is of great importance to consider ovarian endometrioma in the differential diagnosis. In general, endometrioma is recognized as an ovarian cyst. However, in most cases, the pathology represents pseudocyst with a partial or complete endometrial-like lining with extraovarian adhesions and endometriotic implants which are likely to occur at the sites of ovarian adhesions and at the ceiling of the ovarian fossa. Ovarian endometriomas occur in 17-44% patients with endometriosis and account for 35% of all benign ovarian cysts. The time span from the onset of menarche to the time of endometrioma formation, which requires surgical intervention, has been evaluated to be a minimum of 4 years. The pathogenesis of early-life endometrioma may be different from other types of endometriosis. Diagnosis is often delayed, especially in adolescents, who tend to wait too long before seeking professional help. The three specific aims of treatment in adolescents with endometriosis and endometriomas are control of symptoms, prevention of further progression of the disease as well as preservation of fertility. Increasing evidence demonstrates association between ovarian endometriosis and ovarian cancer. In the present mini-review, we draw the particular attention of clinicians to such a possibility, even if relatively infrequently reported.

Hysterectomy trends for benign indications over a 15-year period in an academic teaching center in Poland: a retrospective cohort study

Romanek-Piva K et al., 2016 Ginekologia polska Free to read

The aim of the study was to evaluate changes in the operative trends for various types of hysterectomy due to benign indications, between 2001 and 2015, at the 2nd Department of Gynecology, Medical University of Lublin, as compared to the National Health Service (NHS) registry in Poland. A retrospective cohort study was conducted. Data from the Internal Hospital Discharge Registry and Pathological Results Registry have been compared to the NHS database, which has been available nationwide since 2009. The study group included 5629 women who underwent hysterectomy due to benign indications. During the study period, the following number of procedures were performed: total abdominal hysterectomy - 344 (6.11%), total abdominal hysterectomy with bilateral salpingo-oophorectomy - 1760 (31.27%), total vaginal hysterectomy - 563 (10.00%), subtotal abdominal hysterectomy - 2536 (45.05%), and laparoscopically-assisted subtotal hysterectomy (LASH) - 426 (7.57%). The abdominal route, with the preference for subtotal abdominal hysterectomy, was the main approach to hysterectomy. Symptomatic fibroids were the most common indication for the procedure. Comparison of data collected over the last five years revealed a significant difference in the approach to hysterectomy in favor of subtotal abdominal hysterectomy (SAH) and LASH. Less invasive techniques of hysterectomy (LASH, SAH), which are the preferred choice at the 2nd Department of Gynecology (Lublin), are safe and effective options of treating benign conditions. We are of the opinion that these ap-proaches should be offered to patients instead of more radical techniques. Proper training of physicians may influence the decision-making process in favor of minimally invasive techniques.

Nonabsorbable urethral bulking agent - clinical effectiveness and late complications rates in the treatment of recurrent stress urinary incontinence after 2 years of follow-up

Futyma K et al., 2016 European journal of obstetrics, gynecology, and reproductive biology

Those patients who failed to achieve continence after a procedure aimed to correct it, require a special attitude and precise management due to the sophisticated anatomical and functional field of interest. The purpose of the present study was to assess long-term clinical efficacy and evaluate the frequency and severity of any complications related to recurrent stress urinary incontinence treatment with a non-absorbable bulking agent periurethral injections. Between February 2012-September 2013, 66 patients with recurrent stress urinary incontinence were treated with Urolastic in the tertiary referral gynecologic department. The efficacy of the procedure was assessed objectively at each follow-up visit, scheduled at two, six weeks and 3, 6, 12 and 24 months after primary procedure. Material was injected under local anesthesia according to the manufacturer's instructions, at 10, 2, 4 and 8 o'clock positions with 0.5-1.25ccm per spot. Statistical analyses were performed with Statistica package version 8.0 (StatSoft Inc., Tulsa, OK, USA). A p value <0.05 was considered statistically significant. Objective success rate at 24 months was found in 32.7% of patients, including 22.4% patients who were completely dry. The efficacy of Urolastic, when considering the intention to treat, is 24.2% and 16.7%, respectively. In 4.5% patients an oval shaped material was found inside the bladder. Overall, complications were observed in 17 (25.8%) patients. Although only 30% of patients will benefit from Urolastic injection on the long-term basis it seems to be a safe procedure in the treatment of recurrent stress urinary incontinence.

Should we be more aware of endometrial cancer in adolescents?

Gałczyński K et al., 2016 Developmental period medicine

Although endometrial cancer is generally diagnosed in women after menopause, it may incidentally develop in young women or even in adolescents. Diagnostic tools should be applied in young teenage girls complaining of abnormal genital bleeding, particularly those with hereditary cancer syndromes (such as Cowden or Lynch syndromes). Adolescents affected by polycystic ovary syndrome and obesity may also be at increased risk for the development of atypical endometrial hyperplasia and endometrial cancer, and should be carefully managed when the distressing symptoms occur. In the present article, we briefly summarize the principal clinical correlates associated with endometrial cancer in adolescents.

When and how should we treat cesarean scar defect - isthmocoele?

Futyma K et al., 2016 Ginekologia polska Free to read

The reported number of cesarean sections in Poland is approximately 30% and is associated with increasing number of early and late complications. The myometrial discontinuity at the site of previous cesarean section is known in the literature as "isthmocoele", "niche", "pouch" or cesarean scar defect. In most cases presence of isthmocoele has no clinical significance, but in some patients it may cause abnormal uterine bleeding, dysmenorrhea, dyspareunia, pelvic pain or be associated with secondary infertility. This defect may be treated by laparoscopy, hysteroscopy or vaginal surgery.

[Concentration of selected angiogenic factors in serum and peritoneal fluid of women with endometriosis]

Gogacz M et al., 2015 Ginekologia polska Free to read

Endometriosis is a sex hormone-dependent and successively progressing gynecological disease, characterized by the presence of endometrial tissue outside the uterus. The etiology of endometriosis is known to be multifactorial, and its growth depends on immunological, hormonal, genetic and environmental factors. Angiogenesis plays a key role in implantation and growth of endometriotic lesions, as well as in adhesion formation. Physiologically angiogenesis is responsible for neoangiogenesis and recruitment of new capillaries from the already existing capillaries. It is well-documented that altered angiogenesis provokes improper follicular maturation, infertility recurrent miscarriages, ovarian hyperstimulation syndrome, and carcinogenesis. Factors stimulating angionesis include angiogenin, vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF). The aim of the study was to analyze angiogenic factor concentration (angiogenin, VEGF, FGF) in blood serum and peritoneal fluid in patients with diagnosed endometriosis and idiopathic infertility. A total of 39 patients were recruited for the study including 19 patients (study group) diagnosed with endometriosis during the laparoscopic procedure and 20 patients (control group) with idiopathic infertility and no morphologic changes within the pelvis revealed during the laparoscopic procedure. All patients underwent laparoscopy during the follicular phase of the menstrual cycle. Vein blood sample was obtained before the procedure and during laparoscopy the entire peritoneal fluid was aspirated for further measurement of VEGF, FGF and angiogenin concentrations. Angiogenin concentration in peritoneal fluid was statistically higher in patient with idiopathic infertility in comparison to endometriosis (p<0.05). Higher angiogenin concentration was detected also in blood serum of patients with idiopathic infertility as compared to patients with endometriosis, but no statistical significance was found. VEGF and FGF concentration in blood serum and peritoneal fluid was similar in both groups (p>0.05). There were no significant differences between serum and peritoneal fluid in case of VEGF FGF and angiogenin in any of the groups. Angiogenic factors concentration (VEGF FGF agiogenin) in the peritoneal fluid and blood serum during the follicular phase of the menstrual cycle is not a diagnostic criterion for endometriosis.

Prescribing Safety · Medication Safety in Pregnancy

Is glyburide safe in pregnancy?

Kimber-Trojnar Ż et al., 2014 Current pharmaceutical biotechnology

The clinical recognition and adequate treatment of women with hyperglycemia during pregnancy is significant in order to reduce neonatal complications correlated with gestational diabetes mellitus (GDM). The traditional management of pregnant patients with GDM in whom diet restriction is not sufficient enough involves subcutaneous insulin administration. However, insulin therapy has several disadvantages. It is therefore highly desirable to find an effective alternative to insulin. Glyburide (also known as glibenclamide) is currently classified as Category C by the U.S. Food and Drug Administration (FDA) for use in pregnancy. Despite the fact that the FDA does not approve glyburide for the treatment of GDM, the American College of Obstetricians and Gynecologists (ACOG) recommended in 2013 that: "when pharmacologic treatment of GDM is indicated, insulin and oral medications are equivalent in efficacy, and either can be an appropriate first-line therapy". These conflicting standpoints result from published contradictory data concerning the risks and benefits of the use of glyburide for the treatment of women with GDM. In this focused review we first present the current state of knowledge about the pharmacokinetics and pharmacodynamics of glyburide, including aspects of the transplacental transport and placental metabolism of the drug, and then we comment on several clinical studies describing the use of glyburide for the treatment of women with GDM. Since the contradictory data primarily concern the transfer of glyburide across the placenta, further rigorous scientific researches focusing on this issue are required in order to develop evidence-based recommendations for the use of glyburide for the treatment of women with GDM.

[Electrical cardioversion in the treatment of cardiac arrhythmias during pregnancy--case report and review of literature]

Gałczyński K et al., 2013 Ginekologia polska Free to read

The incidence of cardiac arrhythmias is estimated et 1.2 per 1000 pregnancies, usually in the third trimester and 50% of them are asymptomatic. They may appear for the first time in pregnancy or have a recurring character An important risk factor related to their appearance is the presence of structural heart disease, which complicates < 1% of pregnancies. Generally the symptoms are mild and the treatment is not necessary but in some cases pharmacotherapy is necessary Pharmacotherapy must be a compromise between the potentially adverse effects of drugs on the fetus and the beneficial effects on the cardiovascular system of the mother. Due to the development of cardiac surgery many women with heart defects reach reproductive age and become pregnant. Therefore this problem will be faced more and more often in clinical practice. In addition to pharmacological methods some cardiac arrhythmias may require urgent, life-saving procedures. External electrical cardioversion is associated with the application of certain amount of energy via two electrodes placed on the thorax. It is used to treat hemodynamically unstable supraventricular tachycardias, including atrial fibrillation and atrial flutter Also in hemodynamically stable patients in whom drug therapy was ineffective elective electrical cardioversion can be use to convert cardiac arrhythmia to sinus rhythm. We present a case of a 33 years old patient with congenital heart disease surgically corrected in childhood who had first incident of atrial flutter in pregnancy. Arrhytmia occured in 26th week of gestation. The patient was hemodynamically stable and did not approve electrical cardioversion as a method of treatment therefore pharmacotherapy was started. Heart rate was controled with metoprolol and digoxin, warfarin was used to anticoagulation. Calcium and potassium were also given. Described therapy did not convert atrial flutter to sinus rhythm therefore in 33rd week of gestation after patient's approval electrical cardioversion was performed. Before cardioversion transesophageal echocardiogram was made to exclude the presence of thrombus inside atria. Energy of 50J was applied and sinus rhythm was restored. Cardiotocography during and after cardioversion did not show any significant fetal heart rate changes. Further pregnancy and puerperium were uneventful. Case report and review of the literature about cardiac arrhytmias and methods of its treatment especially in pregnant women. Analysis of medical documentation of the patient treated in the Department of Cardiology as well as in the Department of Obstetrics and Perinatology Medical University of Lublin. Review of abstracts and papers in the Medline database about heart arrhytmias occuring during pregnancy methods of their treatment, with special refference to electrical cardioversion. Pregnancy is a condition which predisposes to cardiac arrhytmias. It is associated with changes in cardiovascular system of pregnant women that appear physiologically They can be effectively treated with low risk for mother and fetus. Electrical cardioversion is an effective and safe method of therapy of supraventricular arrhytmias also during pregnancy The adaptation of the maternal hemostasis in pregnancy predisposes women to an increased risk of thromboembolism therefore anticoagulant therapy is essential to minimize the risk of embolic episodes and stroke during elective cardioversion. Pregnant women with structural or functional heart diseases should be under supervision of multidiscyplinary team of specialists (obstetricians, cardiologists, neonatologists, pediatricians).

[Intracrinology and dehydroepiandrosterone--a new perspective for the use of androgens in hormone replacement therapy in postmenopausal women]

Perzyło K et al., 2011 Ginekologia polska

During menopausal transition not only ovarian production of estrogens but also marked decrease of adrenal androgen production are observed Decreased secretion of adrenal DHEA and DHEA-S result in reduction of peripheral conversion of these steroids into active estrogens and androgens. Intracrinology describes the biosynthesis of active steroids in peripheral target tissues in which the action of theses steroids takes place, without release into the extracellular space or general circulation. DHEA administration to postmenopausal women significantly increases bone mineral density decreases insulin resistance and amount of fat tissue and exerts an estrogenic effect on vaginal cytology in the absence of endometrial stimulation. Moreover animal experiments proved that DHEA suppresses the growth of breast cancer which is yet another reason to consider this steroid as a part of hormone replacement therapy in women.
