Background: Pre-eclampsia (PE) remains a leading cause of maternal and perinatal morbidity and mortality worldwide. Early detection and risk stratification are critical for improving pregnancy outcomes. This review aims to summarize current advancements in PE screening, including clinical risk factors, biomarkers, imaging techniques, and predictive models. Methods: A comprehensive literature search was conducted using PubMed, Scopus, Web of Science, and Google Scholar to identify relevant studies on PE screening and prediction. Peer-reviewed original studies, systematic reviews, and meta-analyses published in English were included, while case reports and conference abstracts were excluded. Results: Traditional screening methods rely on maternal history and clinical risk factors, while emerging approaches incorporate biochemical markers and ultrasound parameters to enhance predictive accuracy. Machine learning models and artificial intelligence (AI)-driven algorithms are being explored for improved risk stratification. However, challenges such as data heterogeneity, lack of external validation, and integration into clinical practice remain. Conclusions: Advances in PE screening hold promise for early identification and targeted prevention strategies. Future research should focus on validating predictive models in diverse populations, integrating AI with traditional screening methods, and developing personalized approaches to reduce PE-associated complications.

Objective 26% of all pregnancies end in miscarriage, and up to 10% of clinically diagnosed pregnancies, and recurrent pregnancy loss is 5% among couples of childbearing ages. Although there are several known causes of pregnancy loss in the first half, including recurrent pregnancy loss, including parental chromosomal abnormalities, uterine malformations, endocrinological disorders, and immunological […] Abstract Objective 26% of all pregnancies end in miscarriage, and up to 10% of clinically diagnosed pregnancies, and recurrent pregnancy loss is 5% among couples of childbearing ages.

At present, the main technological stages of oil production related to drilling operations require the use of a wide variety of drilling mud, which has a complex, multicomponent chemical composition. The drilling mud used and the resulting drilling waste must be safe for human health and the environment. The toxicity and hazard of drilling mud at this point in time remain poorly understood scientific problems and require detailing and studying in toxicological terms. The real degree of hazard and toxicity of drilling mud can only be determined by an experimental method, since its composition, which changes depending on the nature of the technological process and its degree of depletion, is not constant, which can change the toxicological properties. In an experiment conducted on adult male rats, under conditions of a single intragastric injection of drilling mud, new data were obtained regarding the parameters of its toxicity and hazard. The use of a wide variety of methods for determining lethal doses of drilling mud, including the probit analysis method, made it possible not only to substantiate the mean lethal dose of drilling mud but also other parameters of toxicity and survival of animals in the experimental groups. Features of eating behavior and body weight dynamics and the nature of the behavioral reactions revealed by the number and duration of stands and frequency and duration of grooming also indicate the presence of dose-dependent effects.

(1) Background: Lactose digestion depends on persistence genotypes (including rs4988235), the frequency of which exhibits broad geographical variability. However, little is known about the relationship between lactase (LCT) genotypes and intestinal expression of LCT. We aimed to investigate ileal expression of LCT depending on main genetic polymorphisms (rs4988235, rs3754689, rs3739022), age, sex, smoking status, body mass index (BMI), and the expression of other genes; (2) Methods: phenotype, array-based genotype, and ileal mucosal biopsy expression data were obtained from the CEDAR study; (3) Results: analyses included 196 healthy Europeans (53.6% women) aged 53.0 ± 13.6 years with a mean BMI of 25.6 ± 4.2 kg/m², of whom 17.4% were smoking. Ileal LCT expression was mostly independent of age, sex, BMI, or smoking. Rs4988235 homozygous minor allele (GG) associated with lower LCT expression (vs. AG p = 2.2 × 10⁻⁶, vs. AA p = 1.1 × 10⁻⁷). Homozygous major allele of rs3754689 (GG) was related to higher LCT expression (vs. AG p = 1.7 × 10⁻⁵, vs. AA p = 0.0074). Rs3754689 genotype did not modify LCT expression (GG vs. AG p = 0.051) in rs4988235-heterozygous subgroup. Interestingly, CD14, which is a marker of monocytes and macrophages, was the strongest negative transcriptomic correlate of LCT expression (r = −0.57, p_FDR = 1.1 × 10⁻¹⁴); (4) Conclusions: both rs4988235 and rs3754689 associated with ileal LCT expression, which did not seem related to age, sex, smoking, or BMI. The inverse correlation between LCT and CD14 expression in the ileum is striking and requires further investigation.

Introduction: This study investigates the skin-irritating and skin-resorptive effects of drilling fluid (DF) through acute and subacute experiments conducted on adult rabbits and sexually mature male and female rats. Methods: Acute and subacute experiments were conducted on adult rabbits and sexually mature male and female rats. The acute experiment involved a single exposure to DF, while the subacute study involved repeated dermal exposure. Various physiological, biochemical, and histopathological assessments were performed to evaluate the effects. Results: The results of the acute experiment demonstrated that DF exhibits a mild skin-irritating effect but causes significant irritation to the ocular mucous membranes in rabbits. In the subacute study, dermal exposure to DF led to notable alterations in the physiological and biochemical status of rats, including reduced food and water intake, decreased body weight gain, and significant changes in hematological and biochemical parameters. An increase in the relative count of certain leukocyte populations was observed, with a statistically significant elevation in absolute eosinophil counts in both sexes. Similar trends were observed for basophils and lymphocytes. Moderate elevations in serum enzyme levels (ALT, AST, ALP, GGT, and LDH) indicated systemic toxicity. Morphological and morphometric analysis of the skin further supported the dermal toxicity of DF, revealing epidermal keratinization, marked proliferation of germinative layer cells, and cellular heterotopia. In the basal layer of the epidermis, cells exhibited signs of intracellular edema. The papillary layer showed moderate focal inflammatory infiltrates, while the reticular dermis displayed edema of fibrous structures, swelling of collagen fibers, and increased fiber thickness. Discussion: These findings collectively demonstrate that the tested drilling fluid possesses significant dermal and systemic toxicity, indicating potential health risks for mammals upon repeated exposure.
