How important are elements in polycystic ovary syndrome? Should they be supplemented? A systematic review.

Polycystic ovary syndrome (PCOS) is a multifactorial disorder with unknown etiology. The purpose of this systematic review is to analyze the available clinical trials on elemental supplementation in terms of improving biochemical parameters in women with PCOS. Electronic databases were searched from their inception until February 2023. Randomized controlled trials (RCTs) of PCOS during therapy with elemental supplementation alone or in combination with other elements were analyzed. Recommendations regarding supplementation with elements are not clear. There are many factors to consider, with the primary factor being the type of element and the possibility of supplementation and a balanced diet. Another aspect to consider is the presence of comorbidities, which may increase the demand for and absorption of elements. A final factor to be considered is the determination of the body's need for specific elements. Some elements may require supplementation (e.g., magnesium, selenium, iodine, calcium), while others (e.g., iron, copper, potassium, zinc, manganese, chromium) are in sufficient amounts in a proper diet, and some should be limited (e.g., sodium, phosphorus). It is necessary to determine the optimal dose of each element in order to improve the biochemical parameters of PCOS as much as possible, while at the same time avoiding the negative effects of excessive consumption.

Intrauterine deaths - an unsolved problem in Polish perinatology.

OBJECTIVES: The Polish criteria for "intrauterine death" include fetal demise after 22 weeks of gestation, weighing > 500 g and body length at least 25 cm, when the gestational age is unknown. The rate of fetal death in Poland in 2015 is 3:10,000. In 2020, 1,231 stillbirths were registered. MATERIAL AND METHODS: An analysis using 142,662 births in the period between 2015-2020 in 11 living in Poland. The first subgroup was admitted as patients > 22 to the beginning of the 30th week of pregnancy (n = 229), and the second from the 30th week of pregnancy inclusively (n = 179). In the case of women from both subgroups, there was a risk of preterm delivery close to hospitalization. RESULTS: It was found that stillbirth in 41% of women in the first pregnancy. For the patient, stillbirth was also the first in his life. The average stillbirth weight was 1487 g, the average body length was 40 cm. Among fetuses up to 30 weeks, male fetuses are born more often, in subgroup II, the sex of the child was usually female. Most fetal deaths occur in mothers < 15 and > 45 years of age. CONCLUSIONS: According to the Polish results of the origin of full-term fetuses > 30 weeks of gestation for death in the concomitant antenatal, such as placental-umbilical and fetal hypoxia, acute intrapartum effects rarely, and moreover < 30 Hbd fetal growth restriction (FGR), occurring placental-umbilical, acute intrapartum often.

Guidelines of the Polish Society of Gynecologists and Obstetricians, the Polish Society for Vaccinology, and the Polish Society for Family Medicine on vaccinating women with reproductive plans and pregnant or breastfeeding women.

The following Guidelines present the most up-to-date treatment and management recommendations, which may be modified and altered after detailed analysis of a specific clinical situation, which in turn might lead to future modifications and updates.

Pregnancy-associated gastric cancer.

Gastric cancer is a very uncommon diagnosis in pregnancy (app. 1/1000 pregnant women), which has a significant impact on the health and life of mother and fetus and can impede the diagnostic and therapeutic process. Oncological vigilance, not underestimating the symptoms, and decisions made ahead of time could increase the chances of survival. Authors are describing the case of pregnancy-associated gastric cancer, diagnosed on the basis of the histopathological result from samples taken during a laparotomy with cesarean section performed due to a suspected gastrointestinal perforation in the 3rd trimester of pregnancy.

Influence of Entonox (mixture of 50% nitrous oxide and 50% oxygen) on physiological labor and neonatal outcome in own material.

OBJECTIVES: The aim of the study was to compare maternal and neonatal outcome of delivery with inhaled anesthesia to delivery without pain control. MATERIAL AND METHODS: Authors performed retrospective analysis of 260 term deliveries. In the study group (130 women) a mixture of nitrous oxide and oxygen was used. The control group included 130 patients who used no pain relief during delivery. RESULTS: In nulliparas the pain assessment in 11-points scale was similar in both groups, but the labor was longer (350 ± 152 vs 228 ± 113 minutes; p < 0.001 for the first stage and 46 ± 37 vs 18 ± 18 minutes; p < 0.001 for the second stage), episiotomy incidence was higher (81.4% vs 41.9%; p < 0.001) and perineal laceration lower (2.3% vs 25.7%; p < 0.001) in the study group. In multiparas the pain assessment was lower in the study group (5 vs 7 points; p = 0.006), oxytocin was administered more frequently (45.5% vs 21.4%, p = 0.011), but labor duration was the same in both groups. Episiotomy was more frequent (61.4% vs 37.5%, p = 0.02), but there was no difference in perineal laceration. Apgar score was the same in the study and control group. CONCLUSIONS: We found that Entonox prolongs labor significantly and increases frequency of episiotomy in primiparas with no clear analgesic effect. Offering Entonox to the patients giving birth for the first time is thus questionable. In multiparas it has a good analgesic effect but increases probability of episiotomy with no significant influence on perineal tear, what seems not very high cost of decreased pain related to delivery.

The Polish Society of Gynecologists and Obstetricians Guideline for the diagnostic assessment and management of multiple-gestation pregnancy complicated by fetal growth restriction.

The aim of the Guideline is to unify the diagnostic-therapeutic management of multiple-gestation pregnancies complicated by fetal growth restriction in at least one fetus.

Loss of E-Cadherin Staining Continuity in the Trophoblastic Basal Membrane Correlates with Increased Resistance in Uterine Arteries and Proteinuria in Patients with Pregnancy-Induced Hypertension.

Pregnancy-induced hypertension (PIH), especially when complicated with pre-eclampsia (PE), could be a life-threatening complication of pregnancy. Pre-eclampsia is one of the leading causes of perinatal morbidity and mortality in women. Pre-eclampsia is mainly characterized by hypertension and kidney damage with proteinuria. Abnormal placentation and altered structure of the placental barrier are believed to participate in the pathogenesis of pregnancy-induced hypertension, leading to PE. In the current study, we aimed to analyze the immunohistochemical expression pattern of E-cadherin and p120, two markers of epithelial-mesenchymal transition, in placental samples derived from a group of 55 patients with pregnancy-induced hypertension, including pre-eclampsia and 37 healthy pregnant controls. The results were correlated with the presence of an obtained early uterine artery flow notching during diastole on Doppler ultrasound. We observed a higher frequency of discontinuous E-cadherin staining in the basement membrane of syncytiotrophoblast in patients with PIH/PE compared to controls (p < 0.001, Fisher's exact test). Moreover, the loss of continuity of E-cadherin expression correlated with the presence of a bilateral early diastolic notch on Doppler ultrasound (p < 0.001, Fisher's exact test) and the presence of proteinuria (p = 0.013, Fisher's exact test). These findings suggest that E-cadherin contributes to the integrity of the placental barrier, and its loss could be an immunohistochemical marker of PE.

Potential of DNA zygosity tests for non-invasive evaluation of risk of complications in twin pregnancies.

OBJECTIVES: To evaluate and compare the potential of DNA analysis and ultrasound examination for diagnosis of high-risk and low-risk twin pregnancies. MATERIAL AND METHODS: Chorionicity of 42 twin pregnancies was determined by routine high-resolution sonographic examination between 10 and 14 weeks of gestation. Zygosity was analysed in umbilical cord blood samples collected immediately after the birth by genotyping of 22 autosomal short tandem repeats used in human identity testing. RESULTS: Routine ultrasound imaging in the first trimester of twin gestations revealed 21 low-risk dichorionic (50%) and 21 high-risk monochorionic pregnancies (50%). DNA typing of umbilical cord blood showed 23 twin pairs with different genotypes (low-risk dizygotic pregnancies, 55%) and 19 twin pairs with identical genotypes (high-risk monozygotic pregnancies, 45%). We found four pregnancies (10%), which were diagnosed sonographically as monochorionic diamniotic, but were identified as dizygotic in postnatal DNA testing. They constituted 19% of all high-risk monochorionic pregnancies detected by ultrasound imaging. CONCLUSIONS: Our results indicate high potential of prenatal DNA testing of zygosity in identification of low-risk and high-risk twin gestations requiring different prenatal care, especially in cases when chorionicity and zygosity cannot be reliably determined by ultrasound examination and as a supplementary test able to detect gestations misdiagnosed as monochorionic, resulting from fusions of dizygotic placentas. In such cases, dizygosity detected prenatally eliminates the need for frequent prenatal visits typical for monochorionic pregnancies. If chorionicity cannot be unequivocally determined and a prenatal DNA test detects monozygotic twins, a more pessimistic variant of monochorionic pregnancy should always be assumed.

The possible role of corticosterone in regulating sodium and potassium concentrations in human milk.

OBJECTIVES: The aim of the study was to find the presence of corticosterone as a regular human milk constituent. We have evaluated the correlation of concentrations between the analyzed hormone and sodium and potassium in breast milk and serum. MATERIAL AND METHODS: Hand expressing breast milk samples and median cubital vein blood samples had been taken from 69 healthy, lactating women in early puerperium period (between the 3rd and 10th day) twice, before and after breastfeeding. Corticosterone concentrations in human plasma and breast milk were determined by radioimmunoassayed method. Direct assays were performed before and after breastfeeding, twice. The serum and milk sodium and potassium concentrations were estimated by Flame Emission analyzer CIBA-Corning 480, equipped with an automatic diluter. RESULTS: Corticosterone was found in all milk samples, which is an original observation, and its concentration in milk was a few times lower than in serum. Its concentration values in human serum when were not higher than 3 nmol/L (n = 108) positively correlated with its concentrations in milk, and those exceeding 3 nmol/L (n = 30) have demonstrated a negative correlation. An original finding has shown a positive correlation between concentrations of corticosterone in human serum and of potassium in human milk (r = 0.018, p < 0.03). An attempt was also made to determine the presence of aldosterone in breast milk, but the radioimmunoassay did not reveal its presence. CONCLUSIONS: The results confirm a relation between potassium concentration in milk and serum corticosterone concentration delivered to mammal gland with blood.

Perinatal outcome in preterm premature rupture of membranes before 37 weeks of gestation.

OBJECTIVES: The aim of this study was to assess the maternal and neonatal outcome in patients with preterm prematurerupture of membranes between 22 to 37 weeks of gestation in comparison to preterm birth patients. MATERIAL AND METHODS: Group of PPROM patients consisted of 127 women, the control group counted 141 women whodelivered prematurely. The control group was formed by matching patient with the same gestational age at deliveryand neonatal birth weight to every woman from study group. In both groups speculum and ultrasound examinationswere performed, microbiological swabs were taken. In unclear cases of PPROM tests detecting amniotic proteins, suchas PAMG-1 or IGFBP-1, were performed. According to gestational age at delivery, neonates were divided into subgroups:extremely premature infants (< 27 weeks 6 days), moderate premature infants (from 28 weeks 0 days to 33 weeks 6 days),late premature infants (from 34 weeks 0 days to 37 weeks 0 days). RESULTS: In the study group, median gestational age of delivery was 34 weeks 1 day and the same in control group - 34 weeksand 5 days (p > 0.05). Parameters of inflammatory status were more often reported in the PPROM group than in the pretermbirth group, even if they weren't statistically significant (positive culture of cervical swab, increased leukocytosis, CRP above 5).The rate of neonate survival was similar in both groups (93.7% and 94.1%). Congenital infection was more often diagnosed ingroup of neonates from PPROM pregnancies than in neonates from control group; (36% and 21.2% respectively; p = 0.009). CONCLUSIONS: Our research appears to be consistent with theory of inflammatory etiology of PPROM. Optimal managementof infection in PPROM patients seems to be the most important in efforts to prolong pregnancy.

Genotyping of STR and DIP-STR Markers in Plasma Cell-Free DNA for Simple and Rapid Noninvasive Prenatal Diagnosis of Zygosity of Twin Pregnancies.

Due to the high rate of complications, special medical care must be provided especially for monozygotic twin pregnancies, which are characterized as having 2.5 times higher mortality of fetuses. In recent years, examination of cell-free DNA (cfDNA) circulating in maternal plasma has become a useful noninvasive method of prenatal diagnosis. However, fetal DNA constitutes only 3-20% of plasma cfDNA during pregnancy. Short tandem repeats (STRs) are routinely used in forensic examination of DNA mixtures and are able to identify 5% minority components. Haplotypes of deletion/insertion polymorphisms and STRs (DIP-STRs) are able to detect even 0.1% minority components of DNA mixtures. Thus, STRs and DIP-STRs seem to be a perfect tool for detection of fetal alleles in DNA isolated from maternal plasma. Here, we present a novel noninvasive prenatal diagnosis technique of determination of pregnancy zygosity based on examination of feto-maternal microchimerism of plasma cfDNA with the use of STRs and DIP-STRs. Our preliminary results based on 22 STR loci showed 67% sensitivity, 100% specificity and 82% accuracy for prenatal detection of twin dizygosity. The corresponding values for seven DIP-STRs were 13%, 100% and 54%, respectively. Owing to assay performance, low DNA input requirements, low costs (below 10 USD per patient) and simplicity of analysis, genotyping of STR/DIP-STR markers in maternal plasma cfDNA may become a useful supplementary test for noninvasive prenatal diagnosis of twin zygosity in cases when chorionicity and zygosity cannot be reliably determined by ultrasound examination and prognostic value may be provided by a DNA test determining pregnancy zygosity.

Limb body wall complex - the history of the entity and presentation of our series of cases.

We present an analysis of two first historically documented limb body wall complex (LBWC) cases and our own contemporary perinatal autopsy series of this rare complex. So far it was supposed that the first case of this complex was reported in 1685 by Paul Portal. Studying the Joachim Oelhaf's autopsy report from 1613 with attached engraving showing the neonate with multiple birth defects led our research team to a conclusion that it was genuinely the first description of LBWC in the medical literature so far. We compared the Oelhaf's case from 1613 and the Portal's autopsy report from 1685 with our series of LBWC cases dissected in the Medical University of Gdansk between 1999 and 2011. Reviewing 1100 autopsy reports performed we encountered 9 cases of this unique complex. The analysis was supported by the literature review.

Assessment of cardiac function in donor and recipient fetuses during a 7-day follow-up after selective laser photocoagulation of communicating vessels due to TTTS.

OBJECTIVES: The aim of the study was to analyze the changes in cardiac function and myocardial contractility of donor and recipient fetuses with twin-to-twin transfusion syndrome (TTTS) subjected to selective laser photocoagulation of the communicating vessels (SLPCV), between and after the procedure. Finally, we verified if fetuses with Quintero's stage I TTTS presented with early impairment of myocardial contractility. MATERIAL AND METHODS: We selected 77 consecutive women with twin pregnancies, whose both fetuses survived at least seven days post-SLPCV. Myocardial contractility of both fetuses was evaluated ultrasonographically, and their myocardial performance indices (Tei-Index values) and shortening fractions (SF) were determined. RESULTS: In donor fetuses, the Tei-Index values for both right and left ventricle remained within the respective reference ranges both before the procedure and during a 7-day follow-up. A significant change in shortening fraction values for the left ventricle in recipient fetuses and the right ventricle of in the donors was observed during a 7-day follow-up. CONCLUSIONS: Comparison of the cardiac parameters of donors and recipients revealed significant differences in Tei-indices during the entire follow-up period. The group with Quintero's I stage TTTS included 74% of recipient fetuses with abnormal Tei-Index values for the right ventricle (mean 0.53).

Socio-demographic and psychological determinants of exclusive breastfeeding after six months postpartum - a Polish case-cohort study.

OBJECTIVES: The purpose of this study was to explore the socio-demographic and psychological factors connected with exclusive breastfeeding after 6 months postpartum. MATERIAL AND METHODS: A total of 251 women filled in questionnaires in the first week postpartum, then again after 3 and 6 months. The questionnaires included socio-demographic and medical questions, as well as psychological tools: the NEO-FFI Personality Inventory, the Berlin Social Support Scales (BSSS), and the Edinburgh Postnatal Depression Scale (EPDS). Further detailed questions concerning breastfeeding were relevant to this study. RESULTS: The rate of exclusive breastfeeding after 6 months was 39.68%. It was found that exclusive breastfeeding was most strongly connected with attending prenatal classes (ORa = 2.84, CI 1.18-6.87, p = 0.01), formula supplementation after 3 months (ORa = 0.01, CI 0.002-0.08, p < 0.001) and the mother's subjective satisfaction with feeding the infant after 3 months (ORa = 1.44, CI 1.01-2.06, p = 0.04). No other psychological (as far as personality, social support or risk of postpar-tum depression are concerned), demographic or medical factors were significant. Only factors pertaining to breastfeeding were significant. CONCLUSIONS: The prevalence of exclusive breastfeeding in Poland is unsatisfactory. Women should have easy access to prenatal classes with the most up-to-date knowledge on lactation and be advised against supplementing with formula, whenever possible. This could lead to higher satisfaction with breastfeeding.

Early vesico-amniotic shunting - does it change the prognosis in fetal lower urinary tract obstruction diagnosed in the first trimester?

OBJECTIVES: The aim of the study was to assess the outcome of vesico-amniotic shunting performed before 16 weeks of pregnancy in fetuses with severe megacystis diagnosed in the first trimester of pregnancy. MATERIAL AND METHODS: Between January 2008 and October 2012 severe megacystis with the bladder length > 15 mm was diagnosed in 17 fetuses. The procedure of early vesico-amniotic shunting (VAS) was offered to 8 patients with presumably isolated LUTO. The procedure of VAS was performed in 6 fetuses. Before the intervention one or two procedures of vesicocentesis and urine analysis were performed. RESULTS: In all treated cases shunts provided urinary tract decompression. All babies were born prematurely, 2 of them died due to premaurity, 3 of them survived and have normal renal function at the age of 5-6 years. In 4/5 children accompanying malformations were later diagnosed, in 1 born prematurely neonate necropsy was not performed. CONCLUSIONS: Our results suggest that early vesico-amniotic shunting in fetal LUTO is feasible and may potentially prevent not only pulmonary hypoplasia but also renal insufficiency. However, the rationale of the procedure needs further investigation due to a high risk of long-term morbidity and co-existing malformations in children Before offering the therapy detailed counseling of the parents about the possible pros and cons of the therapy is necessary.

Medical and psychosocial determinants of risk of postpartum depression: a cross-sectional study.

OBJECTIVE: The aim of this study was to investigate the degree of risk of maternal postpartum depression during the second month of puerperium. METHOD: In total, 387 postnatal women filled out a questionnaire concerning their health and social status, as well as the following tests: the Edinburgh Postnatal Depression Scale (EPDS), the Patient Health Questionnaire-9 (PHQ-9), the Neo Five-Factor Inventory (NEO-FFI) Personality Inventory and the Berlin Social Support Scales. After 4-8 weeks, patients responded to another questionnaire with the EPDS and the PHQ-9. RESULTS: In total, 48 patients (12.40%) were found to be at risk of postpartum depression between the fourth and eighth weeks after delivery. Premenstrual syndrome [adjusted odds ratio (ORa)=2.93, confidence interval (CI) 1.30-6.63] and EPDS>12 points during the first week after the delivery (ORa=3.74, CI 1.59-9.04) increased the risk of postnatal depression. A similar role is played by a high result in neuroticism scale of the NEO-FFI (ORa=1.50, CI 1.17-1.92) and a positive family history of any psychiatric disorder (ORa=1.03, CI 1.01-1.06). CONCLUSION: A history of premenstrual syndrome and a higher risk of affective disorder soon after a childbirth are associated with greater chances of depressive symptoms in the second month postpartum. This is also the case if a patient is neurotic and has a relative with a history of any psychiatric disorder. Such women should have their mental status carefully evaluated.

Cervical elastography during pregnancy: clinical perspectives.

Uterine cervix is a part of the uterus responsible for maintaining pregnancy till term. As long as the cervix remains long and firm and its internal orifice (os) is closed, it can withstand enlargement of the uterine contents and resultant growing pressure. Mechanical properties of the cervix change during pregnancy; the cervix ripens prior to delivery, then effaces and dilates with contractions of the uterus. Ripening of the cervix can be assessed using the Bishop score and ultrasonographically determined length of the cervical canal and internal os. Consistency is one of the cervical properties that change during the course of the maturation process. Until recently, cervical consistency has been assessed only manually, but in 2007, the first report on elastographic imaging of the cervix during pregnancy has been published. Elastography presents the ability of a tissue to deform under pressure. The softer the tissue, the easier it changes its shape. Different methods of elastography are used - static, when tissue displacement in response to manual compression or physiological movements of vessels is measured, or dynamic, when the speed of shear wave propagation is determined. Irrespective of the method, elastography provides information on the internal os stiffness; this parameter, impossible for manual assessment, was shown to correlate with pregnancy outcome and is a strong predictor of preterm delivery or successful labor induction. Although elastography seems to be a highly promising diagnostic option, still no consensus has been reached regarding an optimal method for uterine cervix assessment, and virtually all previous studies of various elastographic methods produced highly satisfactory results. Future studies need to identify the most promising and objective elastographic method which may serve as a novel tool for pregnancy management, preventing adverse events, such as preterm delivery and unsuccessful labor induction.

Screening for maternal postpartum depression and associationswith personality traits and social support. A Polish follow-upstudy 4 weeks and 3 months after delivery. / Ryzyko depresji poporodowej a cechy osobowosci i wsparcie spoleczne. Polskie przesiewowe badanie obserwacyjne matek 4 tygodnie i 3 miesiace po porodzie.

OBJECTIVES: To investigate the likelihood of postpartum depression and to explore maternal characteristics in terms of personality, social support and other medical and psychological data. METHODS: A sample of 548 patients was investigated 4 weeks and 3 months after delivery. They responded to questionnaires containing sociodemographic questions: the EPDS (Edinburgh Postnatal Depression Scale), the PHQ-9 (Patient Health Questionnaire-9), theNEO-FFI (Personality Inventory), and the BSSS (Berlin Social Support Scales). RESULTS: Probable depression any time during first 3 months postpartum was prevalent among 6.38% of women, based on the following criteria: EPDS > 12 points and PHQ-9 > 9 points. A score of EPDS > 9 in the first week after delivery (ORa = 4.16; CI 1.59-10.86), a history of hospitalisation during pregnancy (ORa = 3.51; CI 1.32-9.20), a high level of neuroticism (ORa = 1.37; CI 1.05-1.77), and high buffering-protective social support (ORa =2.56; 1.25-5.23) were significantly associated with depressive symptoms. Potential protective factors were initial breastfeeding (ORa = 0.31; CI 0.11-0.90) and high satisfaction with currently received social support (ORa=0.41;CI 0.22-0.79). The total dropout rate was 23%. CONCLUSIONS: New mothers who are neurotic and who suffered from physical or mental problems during pregnancy and puerperium might experience depressive symptoms more easily. They would also protect those close to them from negative information about themselves. A lack of initial breastfeeding and unsatisfactory social support played a similar role.
