RESUMEN
OBJECTIVE: To evaluate prenatal ultrasound markers for distinguishing simple gastroschisis (sGS) from complex gastroschisis (cGS) and identifying fetuses at risk of complications. STUDY DESIGN: A retrospective cohort study analyzed 61 fetuses with isolated gastroschisis at a tertiary center from 2011 to 2021, utilizing serial ultrasounds from 14 to 35 weeks' gestation. A general linear model, quantile regression, and logistic regression assessed ultrasound markers, fetal weeks, and gastroschisis risk, yielding predictive models. RESULTS: IABL dilatation showed the highest PPV but low NPV. Non-free floating bowel loops (NFFBL) indicated the best PPV to NPV ratio. Combinations of markers yielded the highest predictive value for cGS. EABL collapsed and non-free floating bowel loops were significant, consistent risk factors. CONCLUSIONS: Prenatal ultrasounds can predict cGS risk, particularly using IABL dilatation and NFFBL as markers. Accurate assessment requires considering gestational age, qualitative symptoms, emphasizing experienced perinatologists' role and monitoring, particularly after 30 weeks of gestation.
RESUMEN
INTRODUCTION: SARS-CoV-2 unsparingly impacts all areas of medicine. Pregnant women are particularly affected by the pandemic and COVID-19 related liver damage seems to be another threat to maternal and fetal health. The aim of this study is to define liver damage profile including bile acids serum levels in COVID-19 pregnant patients and to determine predictors of disease aggravation and poor obstetrics outcomes. METHODS: This study has been carried out in the Obstetrics and Gynecology Department, at the National Medical Institute in Warsaw, Poland between 01.02.2021 and 01.11.2022 The study cohort comprises 148 pregnant patients with COVID-19 and 102 pregnant controls who has been tested negative for SARS-CoV-2. RESULTS: COVID-19 pregnant patients presented liver involvement at admission in 41,9%. Hepatotoxic damage accounted for 27 (19.85%), cholestatic type was diagnosed in 11 (8.09%) and mixed type of liver injury was presented in 19 (13.97%) of patients. Higher serum levels of AST, ALT, GGT, total bilirubin and bile acids as well as mixed type of liver injury at admission were correlated with severe form of an illness. AST and ALT above upper reference limit as well as hepatotoxic type of liver damage predisposed pregnant patients with COVID-19 to poor obstetrics outcomes. CONCLUSION: Hepatic damage in pregnant women with COVID-19 is a common, mild, transaminase-dominant, or mixed type of injury, and often correlates with elevated inflammatory markers. SARS-CoV-2 test should be performed as a part of differential diagnosis in elevated liver function tests. Although bile acids serum levels were commonly elevated they seems to be clinically irrelevant in terms of pregnancy outcomes. Video Abstract.

This research analysed early neonatal outcomes of complex and simple gastroschisis following planned elective preterm delivery in relation to prenatal ultrasound assessment of bowel conditions. A retrospective study of 61 neonates with prenatal gastroschisis diagnosis, birth, and management at a single tertiary centre from 2011 to 2021 showed a 96.72% survival rate with no intrauterine fatalities. Most cases (78.7%) were simple gastroschisis. Neonates with complex gastroschisis had longer hospital stays and time to full enteral feeding compared to those with simple gastroschisis-75.4 versus 35.1 days and 58.1 versus 24.1 days, respectively. A high concordance of 86.90% between the surgeon's and perinatologist's bowel condition assessments was achieved. The caesarean delivery protocol demonstrated safety, high survival rate, primary closure, and favourable outcomes compared to other reports. Prenatal ultrasound effectively evaluated bowel conditions and identified complex gastroschisis cases.
RESUMEN
BACKGROUND: Obesity is a widely recognised risk factor for chronic and gestational hypertension. Influence of gestational weight gain on blood pressure control throughout the pregnancy is not well characterised. MATERIAL AND METHODS: Women in the third trimester of a singleton pregnancy were recruited to the study. Medical records were analysed and a special survey was conducted to obtain history on hypertensive disorders in pregnancy and weight changes during pregnancy. Blood pressure measurements were taken during the office visit in line with international guidelines. Relationships between gestational weight gain and maximal and office values of systolic and diastolic blood pressure values were analysed. RESULTS: Data of 90 women in normal pregnancy, 40 with gestational hypertension and 21 with chronic hypertension were analysed. Gestational weight gain was 11.9 ± 4.6 kg in the normal pregnancy group, 13.0 ± 5 kg in the gestational hypertension group and 10.6 ± 3.4 kg in the chronic hypertension group. Gestational weight gain positively correlated with both office (r = 0.48; p < 0.001) and maximal blood pressure values (r = 0.34; p = 0.004) in normal pregnancy and with maximal blood pressure values (r = 0.57; p = 0.02) in women with chronic hypertension. No correlation was observed between gestational weight gain and blood pressure values among women with gestational hypertension. CONCLUSION: In normal pregnancy and in women with chronic hypertension greater gestational weight gain is related to higher blood pressure values in the third trimester.

A strict correlation between gestational diabetes mellitus (GDM) and preeclampsia (PE) has been shown in previous studies. This case-control observational study evaluates the influence of concomitant GDM on the severity of PE. Ninety-nine patients were included: thirty-eight with PE without GDM (group 1), fourteen with PE and concomitant GDM (group 2), and forty-seven with uncomplicated pregnancies (group 3). Adverse maternal/fetal and neonatal outcomes were registered. Patients underwent blood sample analysis of serum PlGF, sFlt-1, creatinine levels, and platelet count (PLT). The incidence of preterm birth, FGR, HELLP syndrome, and NICU admission was significantly higher in group 1 in comparison to groups 2 and 3, whereas RDS was diagnosed most often in group 2 in comparison to groups 1 and 3. All studied biochemical parameters differed between the control group and both PE groups; however, there were no differences between patients with PE with and without GDM. The presented study indicates that the coexistence of GDM may mitigate the course of PE. The lack of differences between patients with PE with and without GDM in serum levels of studied biomarkers may also confirm its usefulness in the diagnosis and management of PE in patients with coexisting GDM.
RESUMEN
OBJECTIVE: The main goal of fertility-sparing treatment is pregnancy followed by live birth (i.e., successful pregnancy). The principal objective of our study was to evaluate the successful pregnancy rate in patients with borderline ovarian tumors (BOTs) after conservative treatment. The second goal was to evaluate the safety of the conservative approach. STUDY DESIGN: 110 patients with BOT were retrospectively evaluated. All patients underwent surgical treatment, sparing the uterus and part of at least one ovary. RESULTS: The median age was 28 years (range 17-40 years). Serous and mucinous tumors were found in 63 (57%) and 34 (31%) women, respectively. FIGO stage I, II, and III was diagnosed in 101 (91.8%), 3 (2.7%), and 6 (5.5%) patients, respectively. The 3- and 5-year progression-free survival was 82.5% and 78.2%, respectively. Recurrent disease was treated conservatively in 14 women, whereas 3 patients underwent radical surgery. Fifty-six (50.9%) patients got pregnant and had at least one live birth. A total of 83 children were born. A significant difference in the successful pregnancy rate was found in patients diagnosed ≤ 35 years vs. > 35 years old (55.6% vs. 9.1%, respectively; p = 0.003). Surgical approach (laparoscopy vs. laparotomy) did not influence the chance of childbirth. Pre-term delivery constituted 6.25% of all births. CONCLUSIONS: Fertility-sparing surgery should be proposed to young women wishing to preserve fertility. The rate of spontaneous pregnancy is approximately 50%.The risk of relapse is significant but always of borderline histology and may be successfully treated by the second surgery.

Glutathione plays a key role in maintaining a physiological balance between prooxidants and antioxidants in the human body. Therefore, we examined the influence of maternal smoking as a source of oxidative stress measured by total oxidant capacity (TOC) on reduced glutathione (GSH), oxidized glutathione (GSSG), glutathione peroxidase (GPx-3), and reductase (GR) amount in maternal and umbilical cord blood in 110 (45 smoking and 65 non-smoking) mother-newborn pairs. Concentrations of glutathione status markers and TOC were evaluated by competitive inhibition enzyme immunoassay technique. Plasma TOC levels were significantly higher and the GSH/GSSG ratio, which is considered an index of the cell's redox status, were significantly lower in smoking women and their offspring than in non-smoking pairs. Decreased GR levels were found in smoking mothers and their newborns compared with similar non-smoking groups. Although plasma GPx-3 concentrations were similar in both maternal groups, in the cord blood of newborns exposed to tobacco smoke in utero they were reduced compared with the levels observed in children of tobacco abstinent mothers. Oxidative stress generated by tobacco smoke impairs glutathione homeostasis in both the mother and the newborn. The severity of oxidative processes in the mother co-existing with the reduced potential of antioxidant systems may have a negative effect on the oxidative-antioxidant balance in the newborn.
RESUMEN
Preeclampsia affects about 3-8% of all pregnancies. It represents a complex and multifaceted syndrome with at least several potential pathways leading to the development of disease. The main dogma in preeclampsia is the two-stage model of disease. Stage 1 (placental stage) takes place in early pregnancy and is thought to be impaired placentation due to inadequate trophoblastic invasion of the maternal spiral arteries that leads to reduced placental perfusion and release of numerous biological factors causing endothelial damage and development of acute maternal syndrome with systemic multiorgan failure (stage 2-the onset of maternal clinical symptoms, maternal stage). Recently, in the light of the vast body of evidence, two-stage model of preeclampsia has been updated with a few novel pathways leading to clinical manifestation in the second part of pregnancy. This paper reviews current state of knowledge about pathophysiology of preeclampsia and places particular focus on the recent advances in understanding of uterine artery remodeling alterations, as well as the role of microRNAs in preeclampsia.

BACKGROUND Between April and September 2020, there were <10 000 reported cases of COVID-19 in the Masovia district, Poland, and <1000 new cases daily in Poland. During this period, all new hospital admissions to a maternity unit of a teaching hospital in Warsaw were screened for the COVID-19 infection. This retrospective study presents the findings from the reverse transcription-polymerase chain reaction (RT-PCR) test for COVID-19. MATERIAL AND METHODS This study included 838 women admitted for delivery between April 20 and September 20, 2020. All the admitted women were assigned to a low-risk or a high-risk group for COVID-19 and underwent RT-PCR nasopharyngeal swab tests (GeneFinder™-COVID-19-Plus-RealAmpKit. OSANG Healthcare Co., Ltd., Gyeonggi-do, Korea) for COVID-19. The testing protocol included repeated testing in case of inconclusive results or negative results in the symptomatic patients. The maternal and neonatal data from these cases were collected and analyzed. RESULTS All of the 838 women tested negative for COVID-19. Two women (0.24%) were classified as high risk for COVID-19. For 4 (0.48%) women, the results were initially inconclusive and negative when repeated. One hundred and eighty-one (21.5%) women presented with comorbidities, and 60 (7.2%) women were ≥40 years old. CONCLUSIONS The findings from this study show that between April and September 2020, there were no cases of COVID-19 infections at the maternity unit of a teaching hospital in Warsaw, Poland. However, the infection rates for COVID-19 across Europe continue to change. Testing protocols have been developed and established for all hospital admissions and it is anticipated that testing methods will become more rapid and accurate.

The aim of the present study was to analyze the profiles of cardiac microRNAs (miRNAs/miRs) in healthy pregnant women and non-pregnant controls. A total of 61 healthy women >18 years of age with singleton pregnancies in the third trimester were compared with 19 non-pregnant controls. Specifically, expression of miRNAs associated with cardiac hypertrophy (miR-1, miR-17-5, miR-22, miR-34a, miR-124, miR-133a, miR-195, miR-199a-3p, miR-199b, miR-210, miR-222 and miR-1249) and miRNAs associated with cardiac hypertrophy and fibrosis (miR-15b, miR-21, miR-26a, miR-29-a, miR-29c, miR-30c, miR-101, miR-146a, miR-191, miR-208a-5p and miR-328) were analyzed and compared with echocardiographic examination results. Both groups had similar cardiac miRNA expression profiles, but differed in quantitative evaluation. Women in the third trimester of physiological pregnancy exhibited downregulation of certain profibrotic miRNAs (miR-21, miR-30c and miR-328), decreased expression of a hypertrophic and antimetabolic miRNAs (miR-146a), downregulation of an antifibrotic miRNA (miR-222), and downregulation of a hypertrophic miRNA (miR-195). In pregnant women, the indices of systolic function were associated with miR-195 expression, and an interplay between miR-17-5p and diastolic function was observed. While the profiles of cardiac miRNAs expressed in healthy pregnant women and healthy non-pregnant controls were similar, these two groups differed in terms of expression of specific miRNAs. In the third trimester of physiological pregnancy, a downregulation of miR-17-5p, miR-21, miR-30c, miR-146a, miR-195, miR-222 and miR-328 was observed. The differences in the association between echocardiographic indices with miRNAs in pregnant and non-pregnant women suggest that miRNAs regulate both the structure and function of the pregnant heart, influencing cardiac muscle thickness as well as systolic and diastolic function.
RESUMEN
The aim of the study was to determine the relationships between maternal smoking, total adiponectin, high molecular weight adiponectin (HMW adiponectin), selected somatomedins, and the birth weight of newborns. A total of 78 women with a healthy, singleton pregnancy, 41 active smokers and 37 non-smokers, and their offspring were studied. Total and HMW adiponectin, insulin-like growth factor I (IGF-I), and insulin-like growth factor binding protein-1 (IGFBP-1) and 2 (IGFBP-2) were determined in maternal and cord blood by enzyme-link immunosorbent assay. Serum levels of total and HMW adiponectin were lower in smokers compared to the tobacco abstinent in both the mothers (p = 0.013; p = 0.006) and the infants (p = 0.001; p = 0.047). In smoking women and their children, serum concentrations of IGF-I were significantly lower (p = 0.014; p = 0.042), IGFBP-1 significantly higher (p = 0.009; p = 0.039), and IGFBP-2 did not differ from that observed in the non-smoking group. In multivariate analysis performed on the whole group of mothers, the highest impact of serum cotinine and IGFBP-2 levels were indicated for adiponectin and cotinine and the number of cigarettes/day for HMW adiponectin concentration. In correlation analysis estimated separately for smokers and non-smokers, neonatal birth weight was positively associated with total and HMW adiponectin concentrations in umbilical cord blood. Birth weight was also inversely associated with IGFBP-1 and positively correlated with IGF-I levels in maternal serum as well as in cord blood (r = -0.317, p = 0.005; r = -0.294, p = 0.004; r = 0.245, p = 0.031; r = 0.271, p = 0.009, respectively). The present study showed the levels of total and HMW adiponectin in umbilical cord blood may have a significant effect on fetal development. Both IGF-I and IGFBP-1 concentrations also play an essential role in fetal growth, which is an important predictor of birth weight. Cigarette smoking during pregnancy negatively affected adiponectin and the insulin growth factor profile in the serum of women and the cord blood and may be the reason for the lower birth weight of the smokers newborns compared with the nonsmokers offspring.

Pregnancy is a period in life in which women are willing to improve their lifestyle. Providing proper information for these women is crucial for their health and the health of their offspring. Clear information about weak points in their nutritional and weight gain knowledge is the first step for proper health care assistance. There are a few previous studies evaluating the nutritional and weight gain knowledge of pregnant women. In the few studies available, different approaches were taken and there was no wider discussion on the content of the questionnaires attempting to measure level of knowledge. The aim of this study, designed in a pilot fashion, was to test the adequacy of the questionnaire as a research instrument in a group of 139 pregnant Polish women. The developed instrument is a 33-item questionnaire comprising four domains: weight gain, importance of nutrients, quality and quantity of food intake. The results of this study indicate that the questionnaire is stable and internal consistency is acceptable (Cronbach's alpha > 0.7) for dimensions with more than four items. For dimensions with less than four items, internal consistency was poor (Cronbach's alpha < 0.7). The cumulative explained variance for domains weight gain, importance of nutrients, quantity and quality of food intake was 54.74%, 42.74%, 54.42% and 48.99% respectively. Results from validity, reliability and factor analysis indicate that the questionnaire is adequate for its purpose.

Preeclampsia is a multisystem disorder of pregnancy that remains a leading cause of maternal and foetal morbidity and mortality. It is still an underestimated risk factor for future cardiovascular, cerebrovascular, and kidney disease, developing often in the perimenopausal period of a woman's life. It remains unclear whether preeclampsia is an individual risk factor for future cardiovascular, cerebrovascular, and renal events or an early marker of women with high-risk profiles for these diseases. Risk factors for cardiovascular disorders and preeclampsia are very similar and include the following: obesity, dyslipidaemia, insulin resistance, pro-inflammatory and hypercoagulable state, and endothelial dysfunction. Thus, the pregnancy can only be a trigger for cardiovascular alterations that manifest in development of preeclampsia. On the other hand, there is strong evidence that changes in cardiovascular, endothelial, and metabolic systems occurring in the course of preeclampsia may not fully recover after delivery and can be a cause of future disease, especially in the presence of other metabolic risk factors regarding, for example, perimenopause. In this review the authors present current knowledge about short- and long-term maternal consequences of preeclampsia, such as: cardiovascular disease, cerebrovascular incidents (posterior reversible encephalopathy and stroke), kidney injury (including the risk of end-stage renal disease), liver failure, and coagulopathy (thrombocytopenia and disseminated intravascular coagulation).
RESUMEN
The aim of this study was to assess the influence of active tobacco smoke exposure in utero on the concentration of hepcidin and selected iron markers in umbilical cord blood and to evaluate the relationships between these parameters. Newborns of smoking mothers had significantly lower concentrations of serum hepcidin (p < 0.001), iron, and ferritin (p = 0.043; p = 0.042, respectively), but higher levels of erythropoietin (EPO, p < 0.001) and soluble transferrin receptor (sTfR, p = 0.011) compared with newborns of non-smoking women. Negative correlations between cotinine and the number of cigarettes smoked per day with hepcidin serum level (r = -0.33, p = 0.033, r = -0.32, p = 0.041, respectively) and EPO (r = 0.47, p = 0.002; r = 0.46, p = 0.003, respectively) were found. Univariate analysis defined for the whole group of children revealed significant associations between the concentration of hepcidin and other iron status parameters. In the models estimated separately for smokers and non-smokers, we found relations between the level of hepcidin and erythropoietin (B = -0.23, p = 0.004; B = -0.46, p = 0.01, respectively). In the multivariate regression model, a negative association between hepcidin and EPO concentrations in the whole group of newborns (ß = -0.53; p = 0.001) and in the group of smokers (ß = -0.57; p = 0.011) was confirmed. The present study shows significant relations between smoking during pregnancy and hepcidin levels in children born at term. Decreased cord serum concentrations of hepcidin associated with high erythropoietin levels suggest induced fetal erythropoiesis, probably due to the hypoxic effects imposed by maternal smoking.

The concept of early recovery after surgery (ERAS) consists of bundle interventions during the pre-, intra- and postoperative periods and team work. The ERAS, which is a multimodal strategy, enables one to limit the neurohumoral response to the surgery, maintain homeostasis, reduce the risk of complications, shorten the hospital stay, accelerate the return to everyday functioning, improve the patient's satisfaction, achieve a satisfactory quality of life and finally reduce the treatment costs and eliminate any redundant and ineffective practices. Almost every patient can be classified for the ERAS strategy except for patients undergoing urgent and emergency surgery. The necessity to give up ERAS can result from poor organisation and management. Moreover, the procedure itself can be the cause of the lack of adherence to the planned standard. It is necessary to use protocols and checklists. While fulfilling this doctrine, the anaesthesiologist becomes a perioperative specialist.
RESUMEN
A tumor growth depends on the potency of the tumor to support itself with nutrients and oxygen. The development of a vascular network within the tumor is key to its survival. The permanent contest between the tumor and its host involves tumor cells on one side and an immunological system and tissue stroma on the other. The angiogenesis is not only a specialty of the tumor, but it also depends on this complex multidirectional interaction. The most common gynecological cancers, cervical, endometrial and ovarian carcinoma are good examples for studying this problem. In this review, we aim to show that an inflammatory response against a tumor can be reverted into an undesirable process leading to the development of a vascular network within the tumor and, subsequently, further growth of the tumor and progression of a disease. Therefore, a key for tumor management should be searched within the immunological system, rather than focused on cell cycle and anti-angiogenic treatment only.

BACKGROUND: The aim of this paper is to describe the third pregnancy trimester, delivery and puerperium in patient with idiopathic pulmonary hypertension. CASE REPORT: a 30-year-old primigravida with idiopathic pulmonary hypertension was qualified for emergency Caesarean section. In the post partum period no improvement in managing pulmonary arterial hypertension was achieved. Because of progressive respiratory and circulatory failure as well as the pulmonary artery pressure exceeding the systemic pressure the AV ECMO was applied on postoperative day 6. During the ECMO period the emergency laparotomy due to bleeding was necessary. The further course of ICU treatment was uneventful. CONCLUSION: In described case things are left to chance or goodwill of specialists and final outcome depend on happy coincidences.

Perinatology is a dynamically developing field of medicine. The progress of technology in recent decades has made it possible to recognize birth defects very early, including those which are lethal or genetically determined. In many clinical situations, it is no longer possible to work alone to reach a definitive diagnosis, plan treatment or predict the clinical course of the affected fetus/newborn. There is a need for teamwork, which ensures the proper, early care starting in the fetal period, not only in the delivery room or NICU. This paper discusses the ethical foundations of creating interdisciplinary teams, taking as an example the Interdisciplinary Team for Fetal Malformation at the Institute of Mother and Child in Warsaw, which has been active for 25 years, and presents how it works in practice. On the basis of the clinical cases that are examined, practical guidelines were formulated for both the work of medical teams and the way parents are informed about the clinical situation of their child and about sharing the care after the birth of the child. A document was also proposed with information on prenatal diagnosis, decisions made by the interdisciplinary team regarding the mother and child, as well as the conclusions resulting from discussions with parents.

Smoking tobacco can impair proper vascular endothelial functioning. This is exhibited through reduced nitric oxide synthesis as well as activity due to accompanying oxidative stress. We examined the relationship between nitric oxide and markers of oxidative stress/antioxidant defense in serum of smoking and non-smoking pregnant women. Subjects included 99 healthy pregnant women, who were tested for nitric oxide (NO), endothelial (eNOS) and inducible (iNOS) nitric oxide synthase, total oxidant capacity (TOC), and total antioxidant capacity (TAC). NO, eNOS, and TAC serum concentrations were significantly lower (p < 0.005), but iNOS (p < 0.05) and TOC (p < 0.001) were higher in smokers than in non-smokers. Multivariate regression analysis showed associations between NO concentration and eNOS, TAC, and smoking status in the whole group of patients. In the model estimated separately for smokers, the highest impact of eNOS (ß = 0.375; p = 0.021) and cotinine (ß = -0.323; p = 0.037) was indicated for NO concentration. In the model of non-smokers, eNOS (ß = 0.291, p = 0.030) and TAC (ß = 0.350; p = 0.015) were important for NO level. Smoking during pregnancy could exacerbate oxidative stress, impair the action of nitric oxide synthases, and adversely affect the balance of oxygen and nitrogen metabolism. Relationships between NO concentrations and TAC in the studied women's blood can confirm the antioxidant nature of nitric oxide.
