Mental Health and Contraceptive Knowledge in High Schoolers: Comparing Remote and In-Person Learning during COVID-19.

Background and Objectives: In response to the COVID-19 pandemic's effects on education, this study delves into the behavioral, mental health, and sexual education characteristics of high school students during 2020-2021 and 2022-2023. Materials and Methods: We evaluated a variety of factors, including substance use, academic performance, sexual activities, mental health support, pandemic-related anxiety levels, and quality of life indicators using standardized instruments such as the SF-36, GAD-7, and WHOQOL-BREF. Furthermore, we addressed specific questions concerning contraception and sexual education during this period. Results: The questionnaires were filled in by 44 students in 2020-2021 and 41 students in 2022-2023. Significant findings included a noteworthy increase in COVID-19 vaccination rates, from 18.2% in 2020-2021 to 39.0% in 2022-2023 (p = 0.033), enhanced perceptions of mental health support during remote learning, from 7.1% to 20.0% (p = 0.044), and a rise in students partaking in reproductive health discussions from 10.7% to 25.0% (p = 0.046). Additionally, there was a marked decline in anxiety regarding the transition back to in-person learning (p = 0.048). Health surveys, such as the SF-36, signaled improvements in both physical and mental health over the years (p = 0.046 and p = 0.019, respectively), while the GAD-7 scores depicted a considerable reduction in anxiety symptoms (p = 0.038). The WHOQOL-BREF results also highlighted a significant uptick in students' mental well-being in 2022-2023 (p = 0.039). Conclusions: As the COVID-19 pandemic ended, high school students exhibited shifts in behavior, health, and education over four academic years, particularly in areas of contraceptive knowledge and mental health outcomes. The pronounced enhancements in vaccination rates, perceptions of mental health support, participation in health conversations, and overall mental wellness emphasize the adaptability and resilience of students in these tumultuous periods, and a general increase in contraceptive knowledge and quality of life during the end of the pandemic.

The Impact of Prenatal Vitamin D on Enamel Defects and Tooth Erosion: A Systematic Review.

Prenatal Vitamin D has been suggested to be critical for dental health in children, affecting outcomes including the prevalence of enamel defects and tooth erosion. This systematic review aimed to evaluate the potential impact of prenatal Vitamin D levels on these dental health outcomes. A total of seven studies, involving 6978 participants, were included after a comprehensive search of PubMed, Web of Science, and Scopus from 2013 to June 2023. The average age of mothers varied across studies, with Vitamin D levels or supplementation practices displaying significant variation among the study populations. The age of children at examination ranged from 3.6 to 6.6 years. The analysis demonstrated a diverse association between Vitamin D levels and dental outcomes, with enamel defects reported in 21.1% to 64% of the children and opacities ranging from 36% to 79.5% across studies. Maternal Vitamin D insufficiency was identified as a significant risk factor for enamel defects in one study (OR: 3.55), whereas high prenatal Vitamin D levels indicated a protective effect against Hypomineralized Second Primary Molars (OR: 0.84) and Molar Incisor Hypomineralization (OR: 0.95) in another. Conversely, low Vitamin D levels increased the risk of enamel hypoplasia (OR: 1.29) and dental decay. The maternal and child demographics varied greatly across the studies, and the assessment and prevalence of Vitamin D deficiency or insufficiency were heterogenous. This review illuminates the potential influence of prenatal Vitamin D on dental health in children, underscoring the importance of adequate Vitamin D levels during pregnancy. However, more robust research is required to establish the optimal Vitamin D intake during pregnancy to ensure healthy dental outcomes in children.

Comparative Analysis of Hematological and Biochemical Changes in Neonates among Women with and without COVID-19 Infection during Pregnancy.

The aim of this study is to evaluate the test results of neonates delivered by COVID-19-positive mothers during pregnancy with those of neonates born to unvaccinated mothers who are COVID-19-free. A cohort study was conducted on 367 pregnant women who gave birth at Premiere Hospital, Timisoara, Romania, between May 2021 and February 2022. Two groups were established: Group 1, with 167 pregnant women infected with COVID-19, and Group 2, with 200 pregnant women who were not affected by COVID-19 during pregnancy. Maternal laboratory examination did not exhibit significant variations except for platelet count. In neonatal blood tests, WBC had a significantly lower median value in the group born to COVID-19-free mothers. Neonatal anemia and leukocytosis showed slightly higher prevalence in Group 1, but the differences were not statistically significant. This study suggests that maternal COVID-19 infection during pregnancy does not have significant associations with most maternal and neonatal characteristics.

Appropriate Delivery Timing in Fetuses with Fetal Growth Restriction to Reduce Neonatal Complications: A Case-Control Study in Romania.

(1) Background: The main challenge in cases of early onset fetal growth restriction is management (i.e., timing of delivery), trying to determine the optimal balance between the opposing risks of stillbirth and prematurity. The aim of this study is to determine the likelihood of neonatal complications depending on the time of birth based on Doppler parameters in fetuses with early onset fetal growth restriction; (2) Methods: A case-control study of 205 consecutive pregnant women diagnosed with early onset FGR was conducted at the Obstetrics Clinic of the Municipal Emergency Hospital in Timisoara, Romania; The case group included newborns who were delivered at the onset of umbilical arteries absent/reversed end-diastolic flow, and the control included infants delivered at the onset of reversed/absent ductus venosus A-wave. (3) Results: The overall neonatal mortality rate was 2.0%, and there was no significant statistical difference between the two study groups. In infants delivered up to 30 gestational weeks, grades III/IV intraventricular hemorrhage and bronchopulmonary dysplasia were statistically significantly more frequent in the control group. Moreover, univariate binomial logistic regression analysis on fetuses born under 30 gestational weeks shows that those included in the control group are 30 times more likely to develop bronchopulmonary dysplasia and 14 times more likely to develop intraventricular hemorrhage grades III/IV; (4) Conclusions: Infants delivered according to the occurrence of umbilical arteries absent/reversed end-diastolic flow are less likely to develop intraventricular hemorrhage grades III/IV and bronchopulmonary dysplasia.
