Evaluation of the relation between Doppler flow in maternal and fetal vessels and the risk of adverse neonatal outcome

Abstract Aim: The study aimed at: 1. analysis of the relationship between Doppler flow in the selected maternal and fetal vessels and the risk of adverse perinatal outcome (APO); 2. multivariate logistic regression model for the assessment the risk of APA. Material and methods: The study population covered 216 pregnant women from Lodz and Kalisz between 2003-2006. Results: In univariate logistic regression model PI_UA significantly influenced the risk of APO. That risk was increasing 1.2 times, if the PI_UA value was 1/10th higher than the measured unit. Abnormal cardiotocography (CTG) pattern was related to 12-times higher risk of APO. In cases of abnormal PI_MCA, the risk of APO was 2.5 times higher than when PI_MCA was within the normal range. Abnormal PI_UA was related to 11.5-times higher risk of APO. Similarly, when PIV_DV was abnormal, the risk of APO was 2.3-times higher. Low birth weight (LBW) was connected with the 6-times higher risk of APO. In multivariate logistic regression model, CTG and LBW were the risk factors significantly associated with APA. Abnormal CTG pattern was related to more than 6-times higher increase of the risk of APO, however LBW with nearly 4-times higher risk of APO. Conclusion: Abnormal values of PI in UA and in MCA, abnormal flow in DV, and abnormal CTG pattern, as well as low birth weight, had significant influence on the risk of APO. In multivariate analysis only abnormal CTG and low birth weight were the significant factors of APO

Prevalence and antibiotic resistance of Enterococcus strains isolated from poultry

The aim of this study was to evaluate the frequency of occurrence of bacteria of the genus Enterococcus in poultry, to identify them by means of matrixassisted laser desorption/ionisation time-of-flight mass spectrometry (MALDITOF MS), and to analyse the antimicrobial susceptibility of the isolated strains to the drugs most frequently used in poultry. The material for the bacteriological tests was obtained mainly from the heart (97%) of the birds investigated. Of a total of 2,970 samples tested, 911 (30.7%) tested positive for Enterococcus spp. Enterococci were detected in broilers (88.1%), laying hens (5.3%), turkeys (3.9%), breeding hens (2.2%), and geese (0.4%). The most commonly identified species were Enterococcus (E.) faecalis (74.7%), E. faecium (10.1%), E. gallinarum (5.5%), E. hirae (4.6%), and E. cecorum (4.1%). The most frequent resistance properties were resistance to sulphamethoxazole/trimethoprim (88%), tylosin (71.4%), enrofloxacin (69.4%), doxycycline (67.3%), and lincomycin/spectinomycin (56.1%). Only one vancomycin-resistant Enterococcus, E. cecorum from a broiler, was found

The Istállóskő Cave Excavation in 2020 and Its Research Objectives

Istállós-kői-barlang (Istállóskő Cave) is one of the most famous prehistoric sites in the Bükk Mountains of Northeast Hungary. This cave is the most visited archaeological site for tourists in Hungary, due to its location in the valley of Szalajka Stream, a high-tourism area of the Bükk Nature Reserve. The site can be visited freely but is protected by nature conservation laws. The importance of Istállóskő Cave is based on the fact that it is one of the oldest shelters used by the first anatomically modern humans in Europe. Field research that obtained a variety of samples for interdisciplinary studies was carried out decades ago, but the methods for investigating Palaeolithic sites have become more refined since that time. This inspired us to conduct a renewed excavation at the site to understand the ecological aspects of the first anatomically modern humans in Central Europe bette

Tracing human mobility in central Europe during the Upper Paleolithic using sub-seasonally resolved Sr isotope records in ornaments

Mobility of people and goods during the Upper Paleolithic has proven difcult to reconstruct given the relative rareness of remains. Nevertheless, archaeological contexts like the Late Pleistocene horizon of Borsuka Cave (Southern Poland) represent a unique opportunity to explore patterns of objects’ transportation across Central Europe. We investigated the origin of four ornaments made of European elk (Alces alces L.) incisors recovered at Borsuka Cave – the oldest known burial site in Poland, possibly a child grave. Laser-ablation plasma source mass spectrometric analyses of trace elements and Sr isotopic compositions revealed that one elk was roaming within a geologically uniform area while the others changed their pastures during their lifetimes. The non-local origin of the elk teeth is inferred from their exotic Sr isotopic compositions and the lack of evidence for the presence of elk in this territory during the Pleistocene. Instead, the elks’ Sr isotopic composition show good agreement with sites near the Austria-Slovakia border region and northern Hungary, ~250km away from the study site. We argue that the artefacts were most likely brought to Borsuka Cave by humans or by a network of exchange, so far never reported in the time range 32.5–28.8 ka cal BP for Southern Poland

Comparison of Doppler flow in selected maternal and fetal vessels in pregnancies with fetal intrauterine growth restriction

Abstract Objectives: The aim of the study was to compare Doppler flows in materno-fetal circulation in pregnancies with IUGR and small for gestational age (SGA) neonatal weight or normal weight, as well as in uncomplicated pregnancies. Material and methods: The study population comprised 216 pregnant women from Lodz and Kalisz between 2003-2006. In the group I we included 68 women with IUGR observed in prenatal ultrasound examination and SGA neonates, in the group II – 29 women with IUGR observed in US but normal neonatal weight and in the group III – 110 women with normal fetal and neonatal weight. Results: Mean fetal weight in the group II was (2035g400g) and in the group I (1947g414g) and it was lower than in the group III (2765g543g) (
