Aim This study aimed to investigate the cause of respiratory distress syndrome (RDS) in neonates from singleton pregnancies with preterm premature rupture of membranes (pPROM) between 24+0 and 36+6 weeks by using regression analysis for various factors. Methods In 175 singleton pregnancies with pPROM, 95 cases of RDS (54,29%) were diagnosed. In all cases the following information was collected: latency period of PROM, gestational age at birth, Umbilical Artery Pulsatility Index (UA PI), Middle Cerebral Artery Pulsatility Index (MCA PI), fetal distress, antenatal steroids use, delivery type, pregnancy hypertension disease, gestational glucose intolerance or diabetes, neonatal laboratory parameters, gender, weight, Apgar score, and other neonatal complications. Logistic regression analysis was used to investigate the effect of variables on RDS. Results The results of logistic regression analysis showed that the following variables are closely correlated with RDS: female gender (OR=0.52; 95%CI:0.28-0,97), antenatal steroids use (OR=0,46; 95%CI:0,34-0,64), abnormal UA PI and MCA PI (OR=2.96; 95%CI:1,43-6,12) (OR=2.05; 95%CI:1,07-3,95), fetal distress (OR=2.33; 95%CI:1,16-4,71), maternal HGB (OR=0.69; 95%CI:0,5-0,96), and neonatal RBC, HGB (OR=0.32; 95%CI:0,19-0,55) (OR=0.75; 95%CI:0,65-0,88). Conclusions The main RDS risk factors in premature neonates are gender, abnormal fetoplacental circulation, and fetal distress. The laboratory parameters such as lower RBC and HGB count are observed in infants with RDS.

Background: This study describes the morphology of sesamoid bones in the human hand. Ultrasound imaging was used to record the presence and measurements of sesamoids in 120 hands of 60 healthy, young adults of Caucasian ethnicity. Materials and methods: The mean number of sesamoid bones was 4.16 in the left hand and 4.03 in the right hand. 21.6% of cases showed asymmetry between the right hand and the left. There was a significant difference in the prevalence of sesamoid bones between right and left hand in males in this study. Females show a higher incidence of sesamoid bones overall, but do not demonstrate a significant difference between the sides. Results: Prevalence findings: Two in the 1 st Metacarpophalangeal joint (MCPJ) in 99.2% of cases, with one case of a single bone. One in the 2 nd MCPJ in 43.3% of cases. One in the 5 th MCPJ in 84.2% of cases. One in the 1 st Interphalangeal joint (IPJ) in 83.4%of cases. Aside from that there was one case of sesamoid in the 3 rd MCPJ and separate case of sesamoid in the 3 rd proximal IPJ. Conclusions: Moreover, this study discusses discrepancies of opinion regarding sesamoid bones in morphological research.

There are many arguments for the safety and efficacy of COVID-19 vaccines in pregnancy. The aim of this study is to describe the level of vaccination acceptance, to find the factors that most influence the decision to vaccinate, and to describe the scale of changes in vaccination acceptance influenced by medical information on the safety, efficacy, and benefits of vaccination among pregnant women. A total of 300 patients completed the questionnaire, including 150 in Poland and 150 in the Ukraine. The level of vaccination acceptance was assessed before and after medical consultation. There were 53 (35.3%) patients with the intention to get vaccinated in Poland and 25 (16.7%) in the Ukraine. After consultation with a physician, this increased to 109 (72.6%) in Poland and 69 (46%) in the Ukraine. The main factors influencing the acceptance of vaccinations were the fear of harming the foetus (OR-0.119, CI-0.039–0.324 p < 0.001), complications in pregnancy (OR-0.073 CI-0.023–0.197 p < 0.001), and limitations in the vaccination programme (OR-0.026 CI-0.001–0.207 p < 0.001). Medical information about the safety, effectiveness and benefits of vaccinations among pregnant women, provided during a medical visit, may increase the acceptance of vaccinations by 105.6%, as among Polish patients, and by 176%, as among pregnant women from the Ukraine.

The aim was to assess whether fibroblast growth factor 21 (FGF-21) and adiponectin influence intrahepatic cholestasis of pregnancy (ICP) pathogenesis and whether ursodeoxycholic acid (UDCA) has an impact on their levels. 50 pregnant women with ICP (ICP PW), 50 with uncomplicated pregnancy (HPW) and 50 healthy nonpregnant women (HW) were included. In ICP PW the first blood sample was drawn at the time of diagnosis, while in HPW it was drawn in the 28 th week of pregnancy. The next blood samples were drawn in the 32 nd and 36 th week of pregnancy and one day after delivery. UDCA was administered when ICP was diagnosed. In ICP PW serum FGF-21 concentration was the lowest at the time of diagnosis with an evident increase after UDCA administration. Serum FGF-21 levels were significantly higher in ICP PW than in HPW from the first to the last measurement. There was a negative association between adiponectin and bile acids (BAs) levels in the later stage of pregnancy in ICP PW. Up-regulated FGF-21 serum levels in ICP patients compared to HPW persisted after delivery, suggesting its role in disease pathophysiology. The negative association between serum adiponectin and BAs of the later stage of pregnancy may suggest its role in regulation of BAs concentration. UDCA exerts a beneficial effect on insulin sensitivity and up-regulates FGF-21 in ICP.
