Few high-performance liquid chromatography–tandem mass spectrometry (LC-MS/MS) methods have been developed for the full quantitation of fatty acids from human plasma without derivatization. Therefore, we propose a method that requires fewer sample preparation steps, which can be used for the quantitation of several polyunsaturated fatty acids in human plasma. The method offers rapid, accurate, sensitive, and simultaneous quantification of omega 3 (α-linolenic, eicosapentaenoic, and docosahexaenoic acids) and omega 6 fatty acids (arachidonic and linoleic acids) using high-performance LC-MS/MS. The selected fatty acids were analysed in lipid extracts from both free and total forms. Chromatographic separation was achieved using a reversed phase C18 column with isocratic flow using ammonium acetate for improving negative electrospray ionization (ESI) response. Mass detection was performed in multiple reaction monitoring (MRM) mode, and deuterated internal standards were used for each target compound. The limits of quantification were situated in the low nanomolar range, excepting linoleic acid, for which the limit was in the high nanomolar range. The method was validated according to the U.S. Department of Health and Human Services guidelines, and offers a fast, sensitive, and reliable quantification of selected omega 3 and 6 fatty acids in human plasma.

Worldwide, oral cancers represent the 6th most common type of cancer. Oral squamous cell carcinoma (OSCC), which is the most common type of oral cancer, is present in about 90% of the patients with this malignancy. OSCC presents a survival rate up to 80%, if it is detected in an early stage (T1), but if detected at later stages (T3 - T4) the survival rate decreases to 20 - 30%. Due to these survival rates, it is obvious that there is an urgent need to introduce new molecular biomarkers for the early, noninvasive diagnosis of oral cancers from saliva. These biomarkers will aid in increasing the survival rate of the patients for the long-term. MicroRNAs are part of a class of small, non-coding RNAs that contain 19 - 23 nucleotides. MicroRNAs play an important role in the regulation of biochemical mechanisms, cell proliferation, and other cellular mechanisms in the human body. Recently, due to the developments in the field of molecular genetics, salivary microRNAs became important biomarkers in early detection and monitoring of oral cancers by noninvasive methods. We want to present in this review the most important genetic and epigenetic biomarkers involved in oral carcinogenesis, focusing especially on the salivary microRNAs as biomarkers in early diagnosis of OSCC.

Purpose: We aimed to assess the macular anatomy using spectral domain optical coherence tomography (SD‐OCT), in children born preterm who had laser‐treated retinopathy of prematurity (ROP), and to investigate the relationship between structural changes in macula and visual function.Methods: Thirty‐seven 3–8 years old children were included in the study in two groups: 20 children born preterm [(<34 weeks of gestation, birthweight (BW) <2000 g)] who had laser‐treated ROP in the Neonatology Department, Municipal Clinical Emergency Hospital of Timisoara, Romania; and 17 controls (children born at term, without eye disease, matched for age and gender). Spectral domain optical coherence tomography (SD‐OCT) imaging (Spectralis OCT) was performed at central fovea and 1 mm nasally.Results: In the ROP group (total 34 eyes), we included both eyes in 14 children, and on one eye in six other children. In the control group, both eyes for all 17 children were included. Central fovea thickness (CFT) was significantly higher in children born preterm and with laser‐treated ROP as compared to controls (275 ± 34.8 μm versus 224 ± 27.2 μm; p < 0.001). The laser‐treated eyes with ROP had mean best‐corrected visual acuity (BCVA) = 0.19 logMAR (20/31 Snellen); 35% had BCVA ≥0.3 logMAR (20/40 Snellen). In receiver operating characteristic curve (ROC) analysis, with BCVA as static variable (category 0 = BCVA ≤0.3 logMAR), the CFT cut‐off was 257 μm (sensitivity: 0.917; specificity: 0.661; area under the curve: 0.810, p = 0.001).Conclusion: Years after the laser intervention, central fovea was significantly thicker in ROP laser‐treated children born preterm when compared to controls. Central fovea thickness (CFT) correlated strongly and inversely with BW and gestational age (GA) at birth, while a CFT value above 257 μm was suggestive for suboptimal visual acuity. The proposed cut‐off value needs to be validated in future larger studies.

Background and Objectives: Hypertensive disorders, particularly pre-eclampsia, pose significant risks during pregnancy, affecting both maternal and neonatal health. The study aims to analyze short- and long-term health implications for mothers and their children, comparing those with pre-eclampsia to those without, to improve understanding of risk factors, diagnostic markers, and outcomes. Materials and Methods: This retrospective observational study involved 235 patients, 98 with pre-eclampsia and 137 without, monitored from 2015 to 2018 at the Obstetrics and Gynecology Department of the “Pius Brînzeu” Emergency County Clinical Hospital in Timișoara, Romania. Results: Women with pre-eclampsia were older, had higher BMIs, and more frequently had a family history of pre-eclampsia, hypertension, and diabetes. They also had lower educational and socioeconomic levels and fewer prenatal visits. Biochemical markers such as higher proteinuria, elevated sFlt-1, and lower PlGF were significant in diagnosing pre-eclampsia. Short-term maternal complications like eclampsia, HELLP syndrome, and acute kidney injury were more prevalent in the pre-eclampsia group. Neonatal outcomes included higher rates of preterm birth, low birth weight, and NICU admissions. Long-term mothers with a history of pre-eclampsia had higher incidences of chronic hypertension, cardiovascular disease, kidney problems, diabetes, and mental health disorders. Their children faced increased risks of neuropsychological delays, chronic respiratory issues, behavioral disorders, learning difficulties, and frequent infections. Conclusions: The study highlights the significant short- and long-term health impacts of pre-eclampsia on both mothers and their children. Early monitoring, intervention, and comprehensive management are crucial in mitigating these risks. These findings underscore the need for personalized care strategies to improve health outcomes for affected individuals.
