Color characterization of coatings with diffraction pigments

Coatings with diffraction pigments present high iridescence, which needs to be characterized in order to describe their appearance. The spectral bidirectional reflectance distribution functions (BRDFs) of six coatings with SpectraFlair diffraction pigments were measured using the robot-arm-based goniospectrophotometer GEFE, designed and developed at CSIC. Principal component analysis has been applied to study the coatings of BRDF data. From data evaluation and based on theoretical considerations, we propose a relevant geometric factor to study the spectral reflectance and color gamut variation of coatings with diffraction pigments. At fixed values of this geometric factor, the spectral BRDF component due to diffraction is almost constant. Commercially available portable goniospectrophotometers, extensively used in several industries (automotive and others), should be provided with more aspecular measurement angles to characterize the complex reflectance of goniochromatic coatings based on diffraction pigments, but they would not require either more than one irradiation angle or additional out-of-plane geometries.

The Influence of Maternal Psychological Manifestations on the Mother-Child Couple during the Early COVID-19 Pandemic in Two Hospitals in Timisoara, Romania

Background and objectives: The postpartum maternal physical and psychological state played a fundamental role in the mother−child relationship at the beginning of the COVID-19 pandemic. The aim of the study is to analyze the influence of maternal psychological manifestations on the mother−child couple through three objectives (briefly expressed): (I) Determination of the main acute and chronic conditions of newborns/infants. (II) Verification of the hypothesis of the existence of a link between the following neonatal variables: gestational age, birth weight, number of days of hospitalization, and specific neonatal therapies (oxygen, surfactant, and blood products’ transfusion). (III) Verification of the influence of postpartum maternal psychological status on the mother−child couple through three hypotheses. Materials and methods: This cross-sectional study was conducted in two hospitals in Timișoara, Romania, between 1 March and 1 September 2020, and included 165 mothers and their 175 newborns. Mothers answered the Edinburgh Postnatal Depression Scale, Spielberger’s Inventory of State-Trait Anxiety, and the Collins and Read Revised Adult Attachment Scale. Results: (I) The acute and chronic pathology of the infants in the study group was polymorphic. (II) Large correlations were identified between the following infant variables: gestational age with birth weight, and number of hospitalization days with birth weight, gestational age, and use of blood product transfusion (all p < 0.001). (III) (1) State anxiety was the only significant predictor of number of hospitalization days (p = 0.037), number of acute disorders (p = 0.028), and number of infant chronic diseases (p = 0.037). (2) Maternal depressive symptoms were the only predictor of postpartum maternal attachment (p = 0.018). (3) Depressive symptoms, state, and trait anxiety were non-significant in all models studied (all p > 0.05). Conclusions: Postpartum maternal physical and psychological state plays a fundamental role on the mother−child relationship in the new social and complex family conditions.

The Impact of the COVID-19 Pandemic on Depressive Disorder with Postpartum Onset: A Cross-Sectional Study

BACKGROUND

COVID-19 has led to a global health crisis that is defining for our times and one of the greatest challenges to emerge since World War II. The potential impact of the pandemic on mental health should not be overlooked, especially among vulnerable populations such as women who gave birth during the COVID-19 pandemic.

MATERIALS AND METHODS

The study is a cross-sectional survey conducted from 1 March 2020 to 1 March 2023, during the period of the SARS-CoV-2 (COVID-19) pandemic, based on a retrospective evaluation of 860 postpartum women. The screening tool used to assess symptoms of postpartum depression was the Edinburgh Postnatal Depression Rating Scale (EPDS) questionnaire. The questionnaire was completed both in the Obstetrics and Gynaecology Clinical Sections I and II of the "Pius Brînzeu" County Emergency Hospital in Timisoara, Romania, and online using Google Forms.

RESULTS

The highest severity of postpartum depression symptoms was observed during the COVID-19 pandemic. The results of the study conducted during the period of the SARS-CoV-2 pandemic (COVID-19) showed that the prevalence of major postpartum depressive disorder (EPDS ≥ 13) was 54.2% (466 patients), while 15.6% (134) had minor depressive disorder (10 < EPDS ≤ 12) in the first year after delivery. Comparing these results with those obtained in research conducted before the onset of the pandemic period showed an alarming increase in the prevalence of postpartum depression. The risk factors associated with postpartum depression included the type of delivery, level of education, socio-economic conditions, health status, age, background, and personal obstetric history (number of abortions on demand, parity).

CONCLUSIONS

The effects of the pandemic on mental health are of particular concern for women in the first year after childbirth. Observing these challenges and developing effective measures to prepare our health system early can be of great help for similar situations in the future. This will help and facilitate effective mental health screening for postpartum women, promoting maternal and child health.

Impact of antiplatelet therapy in the development of severe ischemic complications and in the outcome of patients with giant cell arteritis

OBJECTIVE

To evaluate whether concomitant treatment with low-dose aspirin or other antiplatelet agents have an impact on the risk of severe ischemic complications and in the outcome of patients with giant cell arteritis (GCA).

METHODS

A retrospective follow-up study of an unselected population of 121 patients with GCA.

RESULTS

Thirty-seven patients (30.5%) received antiplatelet therapy before the onset of GCA symptoms and continued taking it during the corticosteroid treatment (30 received aspirin and 7 other antiplatelet agents). No statistically significant reduction in the incidence of ischemic manifestations (including jaw claudication, visual manifestations, cerebrovascular accidents, ischemic heart disease, and limb claudication due to large artery stenosis) was observed in this group compared with the remaining patients. When we analyzed follow-up data, we found no significant differences between groups in terms of frequency of relapses and percentage of patients recovered from GCA. Corticosteroid requirements among patients in long-lasting remission were lower in those under antiplatelet therapy, but this reduction was fairly modest, statistically non significant and thus of uncertain clinical significance. Similar results were found when only aspirin exposed patients (n=30) were compared to non-exposed patients. Logistic regression analysis showed that antiplatelet therapy (p=0.54, OR 1.31; 95% CI: 0.54-3.19) had not an independent protective effect against ischemic events when adjusted for age, sex, and the presence of atherosclerotic risk factors.

CONCLUSION

We did not observe a significant benefit derived from the use of antiplatelet therapy in either the incidence of severe ischemic events or the disease outcome. Although our results do not discard a potential therapeutic effect of high-dose aspirin, they do not confirm its suggested protective effect in preventing ischemic complications when used at antiplatelet doses.

Health Impacts of Pre-eclampsia: A Comprehensive Analysis of Maternal and Neonatal Outcomes

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.

Evaluating the Impact of Obsessive-Compulsive Symptoms and Personality Types on Perinatal Depressive Symptoms

Perinatal depression (PPD) presents a significant public health concern, often influenced by psychological and personality factors. This study investigated the impact of personality traits, particularly neuroticism, and obsessive-compulsive disorder (OCD) symptoms on the severity of PPD. The primary aim was to quantify the contributions of these factors to the risk and severity of PPD to enhance early intervention strategies. A total of 47 pregnant women with depressive symptoms per DSM-5 criteria at "Pius Brinzeu" County Emergency Hospital in Timisoara, Romania, were enrolled in this cross-sectional study, as well as 49 women without depressive symptoms as controls. Personality traits were assessed using the NEO Five-Factor Inventory (NEO-FFI), and OCD symptoms were measured using the Obsessive-Compulsive Inventory (OCI). Depression severity was evaluated using the Edinburgh Postnatal Depression Scale (EPDS). This set of questionnaires were administered antepartum and postpartum. The logistic regression analysis highlighted neuroticism as a significant predictor of PPD severity, with an increase in neuroticism associated with a higher risk of PPD (coefficient = 0.24, p < 0.001). Conversely, openness showed a protective effect (coefficient = -0.13, p = 0.009). Higher OCD symptomatology, particularly ordering and hoarding, were linked with increased depression scores. Specifically, the total OCI score significantly predicted the EPDS score (coefficient = 0.03, p = 0.003). Furthermore, significant increases in EPDS anxiety and depression scores were observed in the perinatal period, indicating worsening of symptoms (anxiety coefficient = 0.51; p < 0.001). The findings suggest that personality traits like neuroticism and OCD symptoms significantly contribute to the severity of PPD. Interventions targeting these specific traits could potentially mitigate the risk and severity of perinatal depression, underscoring the need for personalized treatment plans that consider these psychological dimensions.

Incidence and Antenatal Detection of Congenital Heart Malformations-Data from a Tertiary Obstetric Romanian Center

OBJECTIVES

Congenital heart defects (CHDs) are among the most frequent congenital defects, and they significantly burden the healthcare system due to their high mortality rate and high cost of care for survivors. We aimed to highlight the incidence of CHDs in a tertiary center in Western Romania.

METHODS

A retrospective study was carried out between 2018 and 2022 at the "Pius Brinzeu" Emergency County Hospital Timisoara. Relevant information about the mothers and the newborns were collected and statistically analyzed.

RESULTS

The incidence of CHDs from 2018 to 2022 in our center was 5.3%. Eleven types of malformations were diagnosed postnatally in 541 newborns, with 28.8% of cases having more than one type of CHD. The antenatal detection rate was 28%, with the highest rates for tetralogy of Fallot, hypoplastic left heart syndrome, or significant ventricular septal defects and the lowest for pulmonary stenosis. The lower antenatal detection rate was influenced mainly by incomplete or absent prenatal care.

CONCLUSIONS

The incidence of CHDs is clearly dependent of a multifactorial approach, and the results highlight this. With an incidence almost 50% lower than reported within the literature and a low rate of prenatal detections, CHDs could be a more of a burden to endure regarding medical treatment. Improvements in patients' education, prenatal care, and screening programs could improve diagnosis, decrease mortality, and optimize postnatal care.

Genetic Insights and Neonatal Outcomes in Preeclampsia and Eclampsia: A Detailed Analysis of the RS5707 Genotype

BACKGROUND

Preeclampsia (PE) and eclampsia (E) are severe pregnancy complications with significant maternal and neonatal health impacts. This study explores the association of the rs5707 polymorphism in the renin-angiotensin system (RAS) with PE/E and related neonatal outcomes.

MATERIALS AND METHODS

We conducted a cross-sectional study involving 400 mother-newborn dyads at the "Pius Brinzeu" Emergency Clinical Hospital Timisoara. Participants were divided into a control group (254 normotensive women) and a PE/E group (146 women with PE/E). Genotyping for the rs5707 polymorphism was performed using real-time PCR, and statistical analyses assessed associations with maternal body mass index (BMI) and neonatal outcomes.

RESULTS

The AA genotype of rs5707 was significantly associated with a reduced risk of PE/E and more favorable neonatal outcomes, including higher Apgar scores, greater birth weights, and longer gestational ages. Conversely, the AC genotype correlated with increased maternal BMI and adverse neonatal outcomes. Odds ratios highlighted the protective effect of the AA genotype against PE/E and the increased risk associated with the AC genotype.

CONCLUSIONS

This study revealed the critical role of the rs5707 polymorphism in PE/E development and neonatal health. Genetic screening for rs5707 could enhance early identification and personalized intervention strategies, improving outcomes for both mothers and neonates. Further research is needed to validate these findings across diverse populations and to uncover the underlying mechanisms.

Epigenetic and Coping Mechanisms of Stress in Affective Disorders: A Scoping Review

This review aims to explore the intricate relationship among epigenetic mechanisms, stress, and affective disorders, focusing on how early life experiences and coping mechanisms contribute to susceptibility to mood disorders. Epigenetic factors play a crucial role in regulating gene expression without altering the DNA (deoxyribonucleic acid) sequence, and recent research has revealed associations between epigenetic changes and maladaptive responses to stress or psychiatric disorders. A scoping review of 33 studies employing the PRISMA-S (Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Statement) guidelines investigates the role of stress-induced epigenetic mechanisms and coping strategies in affective disorder occurrence, development, and progression. The analysis encompasses various stress factors, including childhood trauma, work-related stress, and dietary deficiencies, alongside epigenetic changes, such as DNA methylation and altered gene expression. Findings indicate that specific stress-related genes frequently exhibit epigenetic changes associated with affective disorders. Moreover, the review examines coping mechanisms in patients with bipolar disorder and major depressive disorder, revealing mixed associations between coping strategies and symptom severity. While active coping is correlated with better outcomes, emotion-focused coping may exacerbate depressive or manic episodes. Overall, this review underscores the complex interplay among genetic predisposition, environmental stressors, coping mechanisms, and affective disorders. Understanding these interactions is essential for developing targeted interventions and personalized treatment strategies for individuals with mood disorders. However, further research is needed to elucidate specific genomic loci involved in affective disorders and the clinical implications of coping strategies in therapeutic settings.

Impact of Stress and Anxiety on Cardiovascular Health in Pregnancy: A Scoping Review

Complex biological processes that enable optimal foetal growth throughout pregnancy are linked to notable haemodynamic and metabolic changes in the mother's body. An inability to adapt to these changes can affect cardiovascular health. During pregnancy, women may experience mood swings, anxiety, and emotional ambivalence. These symptoms can lead to stress and harm the mental well-being of expectant mothers. It is crucial to know the aspects that can influence the development of cardiovascular problems among pregnant women. Effective management requires identifying risk factors. Applying the PRISMA ScR guidelines, we conducted a scoping review to explore and summarise the evidence regarding the impact of stress and anxiety on cardiovascular health in pregnant women. The following enquiries were looked into as research topics: What effects do anxiety and stress have on a pregnant woman's cardiovascular health? How is it quantifiable? It is essential to comprehend the physiological changes that the body undergoes throughout pregnancy in order to inform and assist both patients and medical professionals. This makes it possible for them to identify any pathological disorders or risk factors that could worsen the health of expectant mothers. Psychological and cardiovascular risk factor screening, either before or during pregnancy, may be able to uncover circumstances that require specific medical and psychological therapies in order to lower maternal morbidity and death from cardiovascular disease. Our findings underscore the need for systematic psychological and cardiovascular screening during prenatal care to mitigate adverse outcomes and improve maternal-foetal health.

The Influence of Personality Traits on Postpartum Depression: A Systematic Review Based on the NEO-FFI Scale

Postpartum depression (PPD) is a significant global health concern with profound implications for mothers, families, and societies. This systematic review aims to synthesize current research findings to understand better how personality traits, as assessed by the NEO Five-Factor Inventory (NEO-FFI), contribute to the development and progression of PPD. Conducted in January 2024, this review searched major databases like PubMed, PsycINFO, and Scopus up to December 2023, focusing on the NEO-FFI's role in evaluating PPD. Following PRISMA guidelines, studies were selected based on strict criteria, including the exclusive use of NEO-FFI for personality assessment and a focus on postpartum women. A total of seven studies were included after a rigorous two-step screening process, and their data were qualitatively synthesized. The review covered a total of 4172 participants, with a prevalence of clinically significant postpartum depression symptoms ranging from 10.6% to 51.7%. Notably, Neuroticism emerged as a significant predictor of PPD, with odds ratios ranging from 1.07 (95% CI: 0.96-1.20) in some studies to as high as 1.87 (95% CI: 1.53-2.27) in others. In contrast, traits like Extraversion and Conscientiousness generally showed protective effects, with lower scores associated with reduced PPD risk. For instance, Extraversion scores correlated negatively with PPD risk (Beta = -0.171) in one study. However, the impact of other traits such as Openness and Agreeableness on PPD risk was less clear, with some studies indicating negligible effects. The review highlights Neuroticism as a consistent and significant predictor of PPD risk, with varying impacts from other personality traits. The findings suggest potential pathways for targeted interventions in maternal mental health care, emphasizing the need for comprehensive personality evaluations in prenatal and postnatal settings.
