The aim: To obtain the prevalence of mastitis in the breastfeeding women and antimicrobial resistance of responsible pathogens in Ukraine. Materials and methods: A retrospective multicenter cohort study was based on surveillance data for Postpartum Mastitis and included 18,427 breastfeeding women’s who gave birth in 11 regional hospitals of Ukraine. Results: 22.6% breastfeeding women’s were found to have breast infections. Among these patients, 11.6% breast abscess and 88.4% mastitis were observed. Of the total cases breast infections, 74.8% were detected after hospital discharge. The rate of healthcare-associated mastitis was 8.6%. The predominant pathogens were: Staphylococcus aureus (23.6%), Escherichia coli (19.4%), Enterobacter spp. (11.9%), Staphylococcus epidermidis (10.7%), Klebsiella spp. (8.7%), Pseudomonas aeruginosa (4.8%), Enterococcus faecalis (4.8%), and Proteus mirabilis (4.6%). The overall proportion of methicillin-resistance was observed in 27.9% of S. aureus (MRSA) and 24.3% of S. epidermidis (MRSE). Of the total methicillin-resistance strains, 74.8% of MRSA and 82.1% of MRSE is community-acquired, were detected after hospital discharge. Vancomycin resistance was observed in 9.2% of isolated enterococci. Carbapenem resistance was identified in 7.3% of P.aeruginosa isolates. Resistance to third-generation cephalosporins was observed in 8.8% Klebsiella spp. and E.coli 9.1% isolates. Conclusions: Mastitis in the breastfeeding women in Ukraine requires medical attention it is common, and a lot of cases are caused by pathogens resistant to antibiotics. Optimizing the management and empirical antimicrobial therapy may reduce the burden of mastitis, but prevention is the key element.

The objective: improving the efficiency of diagnosis and treatment of pathology and implantation ability of the endometrium in women of reproductive age who took part in hostilities and received concussions. Materials and methods. The study of endometrial pinopodia was carried out in 35 women of reproductive age who took part in hostilities and received concussions, who on the 21st day of the MC underwent operative laparoscopy and hysteroscopy with endometrial sampling for histological examination and scanning electron microscopy. Of these women, 22 patients – a comparison group – of reproductive age with a history of trauma without post-concussion syndrome and 13 in the main group, women of reproductive age, have the consequences of contusion in the form of post-concussion syndrome. Served as control 10 samples of endometrium from civilian women of reproductive age. The average age of the surveyed was 27.08±4.23 years. The period of stay in the combat zone was 29.34±9.21 months, the time from the moment of receiving a slight traumatic brain injury (contusion) was 18.8±9.2 months. Results. In combatant-women with contusion in history, there are disturbances in the receptivity of the endometrium, manifested by abnormalities in the development of pinopodia and their microvilli during the implantation window: areas without pinopodia in 47.50% of cases (p<0.006), pinopodia of sizes – in 77.50% (p<0.01) and abundant microvilli – in 37.50% (p<0.02); a decrease in the frequency of the presence of developed pinopodia by 2.12 times (p<0.01), large pinopodia by 2.29 (p<0.01), and a small number of microvilli by 4.00 (p<0.0001), an increase in the occurrence of medium-sized pinopodia by 3.00 (p<0.02) times, and a moderate number of microvilli by 4.00 (p<0.0001). A characteristic feature of endometrial pinopodia in the above patients is the presence of mosaicism of their shape (65.00%) and size (67.50%). Conclusions. Women in the military who have been injured in combat are diagnosed with reproductive health problems caused by both the traumatic brain injury itself and the stressors associated with military service. Keywords: reproductive health, female veterans, post-contusion syndrome, receptive endometrial enlargement, office hysteroscopy.

The aim: To obtain the first estimates of the current prevalence of healthcare-associated deep pelvic tissue infection and other infections of the female reproductive tract (vagina, ovaries, uterus) including chorioamnionitis, and antimicrobial resistance of causing pathogens in Ukraine. Materials and methods: We performed a retrospective multicenter cohort study was based on surveillance data. The study population included 3,053 women’s who underwent gynecological surgery or other procedures from 2017 to 2019 in 7 women hospitals in Ukraine. Definitions of healthcare-associated reproductive tract infection were used from the CDC/ NHSN. Results: The prevalence of healthcare-associated deep pelvic tissue infection and other infections of the female reproductive tract was 26.3%. Incidence of infection was: 13.3% Pelvic abscess or cellulitis, 14.6% Adnexa utery, 9.5% Salpingitis, 7.1% Oophoritis, 12.2% Parametritis, 4.6% Chorioamnionitis, and 38.8% Bacterial Vaginitis. The predominant pathogens were: Escherichia coli (25.6%), Enterobacter spp. (11.4%), Klebsiella pneumoniae (10.6%), Staphylococcus aureus (8.5%), Enterococcus faecalis (7.2%) and Pseudomonas aeruginosa (7.1%). Methicillin-resistance was observed in 14.3% of S. aureus (MRSA). The overall proportion of extended spectrum beta-lactamases (ESBL) production among Enterobacteriaceae was 20.8%. The prevalence of ESBL production among E. coli isolates was 24.7% and among K. pneumoniae 11.9%. Resistance to thirdgeneration cephalosporins was observed in 12.8% E.coli and 9.2% K. pneumoniae isolates. Carbapenem resistance was identified in 8.5% of P.aeruginosa isolates. Conclusions: Healthcare associated deep pelvic tissue infection and other infections of the female reproductive tract in Ukraine is a common occurrence and many cases are caused by pathogens that are resistant to antibiotics.

Objective: optimization of pregravid (pre-pregnancy) preparation in patients with tubal-peritoneal infertility factor and marked delay in endometrial development after unsuccessful assisted reproductive technology (ART) treatment by the use of endometrium injection scratching technology with autoplasma.Material and methods. Study included 40 cases of unsuccessful treatment attempts for tubal-peritoneal factor infertility with severe delay of endometrial development and 10 patients with tubal-peritoneal factor infertility with normal endometrium with one or more unsuccessful ART attempts on history and the existence of cryopreserved embryos of satisfactory quality from previous cycles of assisted reproductive technology. The average age was 39.5 ± 3.1 years. Patients were divided into groups: I – 21 patients who underwent endometrial injection scratching and hormonе replacement therapy (HRT) with a standard (4/6 mg) dose of estradiol; II – 19 patients who were prescribed HRT with a standard (4/6 mg) dose of estradiol; control – 10 patients with normal endometrium who underwent cryo-ET with standard (4/6 mg) dose of estradiol.Clinical results were evaluated and compared in terms of pregnancy rate per embryo transfer and pregnancy loss rate in the first trimester. The correspondence of the morphofunctional structure of the endometrium was evaluated by ultrasound, cytologically, Doppler measurements, histologically, immunohistochemically and via selective electron microscopy. Endometrium was 8.9 ± 1.1 mm during the period of progesterone prescription in the cryoembryo transfer cycle. All participants were transferred day 5 embryos. Results. In the cryo-ET program autoplasma injection scratching in patients with marked delay of endometrial development after the first seven days of monotherapy with a starting dose of estradiol was accompanied by a significant improvement in clinical outcomes in terms of pregnancy rate (25%) and definite decrease of early reproductive losses (25%).Conclusions. After pre-pregnancy preparation according to our method, it is quite sufficient to perform HRT with a standard dose of estradiol (4/6 mg/day) before starting progesterone irrespective of the endometrial development degree. Meanwhile, injection scratching is advisable to be prescribed in cases of marked delay in the endometrium development and it should be combined with physiotherapy methods.

The aim: To obtain the first estimates of the current prevalence of healthcare-associated cervicitis (HACs) and antimicrobial resistance of responsible pathogens in Ukraine. Materials and methods: We conducted a retrospective multicentre cohort study was based on surveillance data from January 1st, 2019 to December 31st, 2021 in Ukraine. Antibiotic susceptibility testing was determined by Kirby–Bauer disc diffusion test according to the protocol of the European Committee on Antimicrobial Susceptibility Testing. Results: Of the 6,885 participants in this study, 1746 women (25.5%) met the clinical definition of cervicitis. Prevalence of HACs and cervcits caused sexually transmitted pathogens were 12.7% and 8.3%, respectively. The incidence of HACs among women with a history of gynecological procedures was 25.4%. The main causes of HACs were legal induced abortions (28.8%), vaginal hysterectomy (23.9%), and postpartum instrumental examination (12.8%). The predominant pathogens of HACs were: Escherichia coli, Enterobacter spp., Klebsiella spp., Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis. Methicillin-resistance was observed in 20.8% of S. aureus (MRSA). Vancomycin resistance was observed in 7.4% of isolated enterococci (VRE). Resistance to third-generation cephalosporins was observed in 13.1% Klebsiella spp. and E.coli 17.5% isolates. Carbapenem resistance was identified in 11.6% of P.aeruginosa isolates. The prevalence of ESBL production among E. coli isolates was significantly higher than in K. pneumoniae (33.5%, vs 8.7%). The overall proportion of extended spectrum beta-lactamases (ESBL) production among Enterobacteriaceae was 34.6%. Conclusions: This study showed that the prevalence of healthcare-associated cervicitis in Ukraine is high, and many cases were caused by antibiotic-resistant pathogens.
