ABSTRACT

Psychosis is a hazardous and functionally disruptive psychiatric condition which may affect women in pregnancy, entailing negative consequences for maternofetal well-being. The precise pathophysiological basis and consequences of a psychotic episode in pregnancy remain to be further elucidated. The placenta is a pivotal tissue with many functions in the gestational period, critically influencing the fate and development of pregnancy. Although detrimental alterations have been observed in women undergoing severe psychiatric disorders in pregnancy, there are little studies evaluating the consequences of suffering from a psychotic episode in the placental tissue In this work, we have evaluated the histopathological consequences of a first episode of psychosis in pregnancy (FE-PW; N=22) and compare them with healthy pregnant women (HC-PW; N=20) by using histological, immunohistochemical and gene expression techniques. Our results define that the placental tissue of FE-PW display an increase in the number of placental villi, bridges, syncytial knots and syncytial knots/villi. Besides, we have also observed an enhanced gene and protein expression in FE-PW of the hypoxic marker HIF-1α, together with the apoptotic markers BAX and Bcl-2. To our knowledge, this is the first study demonstrating significant histopathological changes in the placenta of women suffering a new-onset psychotic episode in pregnancy. Further studies should be aimed at deepening the knowledge about the pernicious effects of psychosis in the maternofetal tissues, as well as the potential implications of these alterations.

ABSTRACT

Psychosis is a complex clinical syndrome resulting in a loss of contact with reality and alterations in behavior and sensorial and motor functions. Although the onset of psychosis can be related to any medical condition, most cases of psychosis are not fully understood. Psychosis may manifest for the first time during pregnancy, which is detrimental to maternofetal well-being. The impact of having a first episode of psychosis during pregnancy on the placenta has not yet been explored. Oxidative stress is thought to take part in the etiopathogenesis of this complex disorder, and this condition can also affect the placenta as it is highly sensitive to changes in the maternal environment. In this sense, the aim of the present work was to study the gene and protein expression through RT-qPCR and immunohistochemistry, respectively, of oxidative stress markers (NOX-1, NOX-2, iNOS, eNOS and PARP) in the placental tissue of women who underwent a first episode of psychosis during pregnancy (FE-PW) in comparison to healthy pregnant women. Our results showed augmented gene and protein expression of NOX-1, NOX-2, iNOS and PARP in the placental tissue of FE-PW. For the first time, we demonstrated that oxidative stress may have an important pathophysiological role in this tissue, aiding in explaining the impact of psychosis on pregnancy and the need for future studies in this field to guide better clinical management of these patients.

ABSTRACT

Psychosis is a complex entity characterized by psychological, behavioral, and motor alterations resulting in a loss of contact with reality. Although it is not common, pregnancy can be a period in which a first episode of psychosis can manifest, entailing detrimental consequences for both the fetus and the mother. The pathophysiological basis and study of maternofetal wellbeing need to be further elucidated. Lipid peroxidation and ferroptosis are two phenomena that are tightly linked to the placental dysfunction commonly observed in different complications of pregnancy. In the present study, we aim to explore the histopathological and gene expression of different markers of lipid peroxidation and ferroptosis in the placentas of women who underwent a first episode of psychosis during their pregnancy (n = 22). The aim is to then compare them with healthy pregnant women (n = 20). In order to achieve this goal, iron deposits were studied using Prussian Blue staining. In addition, the protein/gene expression of a transferrin receptor (TFRC), as well as an acyl-CoA synthetase long-chain family member 4 (ACSL-4), arachidonate lipoxygenase-5 (ALOX-5), malondialdehyde (MDA), and glutathione peroxidase 4 (GPX4) were all analyzed through gene expression (RT-qPCR) and immunohistochemical procedures. Our results demonstrate an increased presence of iron deposits that are accompanied by a further expression of TFRC, ACSL-4, ALOX-5, MDA, and GPX4-all of which are observed in the placenta tissue of women who have suffered from a first episode of psychosis. Therefore, in our study, a histopathological increase in lipid peroxidation and ferroptosis markers in the affected women is suggested. However, further studies are needed in order to validate our results and to establish possible consequences for the reported alterations.

ABSTRACT

Psychotic episodes represent one of the most complex manifestations of various mental illnesses, and these encompass a wide variety of clinical manifestations that together lead to high morbidity in the general population. Various mental illnesses are associated with psychotic episodes; in addition, although their incidence and prevalence rates have been widely described in the general population, their correct identification and treatment is a challenge for health professionals in relation to pregnancy. In pregnant women, psychotic episodes can be the consequence of the manifestation of a previous psychiatric illness or may begin during the pregnancy itself, placing not only the mother, but also the fetus at risk during the psychotic episode. In addition, we cannot forget that both pharmacological and nonpharmacological management are complex given the different teratogenic effects of various neuroleptic drugs or mood stabilizers; moreover, the recommendation is that patients should be followed together with different specialists to maintain close contact during puerperium given the high incidence of recurrence of psychotic episodes. In addition, we cannot forget that a large portion of these patients for whom the onset times of such episodes are during pregnancy have a greater probability of an unpredictable psychiatric illness that requires a postpartum follow up, in addition to the postpartum psychotic episodes, at some point in their lives. Therefore, the purpose of this review is to summarize the epidemiology of psychotic breaks during pregnancy related to the main mental illnesses that affect this population and to summarize the main pharmacological treatments available for their clinical management.

ABSTRACT

Pregnancy comprises a period in a woman's life in which the circulatory system is subjected to hemodynamical and biochemical changes. During this period, while restructuring blood vessels and exchanging maternal-fetal products there is an increased risk of developing chronic venous disease (CVD), which may have an echo in life after childbirth for both mother and child. Previously, we investigated that pregnancy-associated CVD involves changes in placental architecture at angiogenesis, lymphangiogenesis and villi morphology compared with healthy controls (HC) with no history of CVD. We aimed to more deeply investigate the oxidative stress response in placenta from women with CVD versus HC through several markers (NRF2, KEAP1, CUL3, GSK-3ß). An observational, analytical, and prospective cohort study was conducted on 114 women in their third trimester of pregnancy (32 weeks). A total of 62 participants were clinically diagnosed with CVD. In parallel, 52 controls with no history of CVD (HC) were studied. Gene and protein expressions of NRF2, KEAP1, CUL3, GSK-3ß were analyzed by real-time polymerase chain reaction (RT-qPCR) and immunohistochemistry. Nrf2 gene and protein expression was significantly greater in placental villi of women with CVD, while Keap1, CUL-3 and GSK-3ß gene and protein expressions were significantly lower. Our results defined an aberrant gene and protein expression of Nrf2 and some of their main regulators Keap1, CUL-3 and GSK-3 ß in the placenta of women with CVD, which could be an indicator of an oxidative environment observed in this tissue.

ABSTRACT

OBJECTIVE: This study aimed to use real-time safety audits to establish whether preparation of the equipment required for the stabilization and resuscitation of newborns in the delivery room areas is adequate. STUDY DESIGN: This was a descriptive, multicenter study performed at five-level III-A neonatal units in Madrid, Spain. For 1 year, one researcher from each center performed random real-time safety audits (RRTSAs), on different days and during different shifts, of at least three neonatal stabilization areas, either in the delivery room or in the operating room used for caesarean sections. Three factors in each area were reviewed: the set-up of the radiant warmer, the materials, and medication available. The global audit was considered without defect when no errors were detected in any of the audited factors. Possible differences in the results were analyzed as a function of the study month, day of the week, or shift during which the audit had been performed. RESULTS: A total of 852 audits were performed. No defects were detected in any of the three factors analyzed in the 534 (62.7%, 95% confidence interval [CI]: 59.3-65.9) cases. Slight defects were detected in 98 (11.5%, 95% CI: 9.4-13.8) cases and serious defects capable of producing adverse events in the newborn during resuscitation were found in 220 (25.8%, 95% CI: 22.9-28.9) cases. No statistically significant differences in the results were found according to the day of the week or time during which the audits were performed. However, the percentage of RRTSAs without defect increased as the study period progressed (first quarter 38.1% vs. the last quarter 84.2%; p < 0.001). CONCLUSION: The percentage of adequately prepared resuscitation areas was low. RRTSAs made it possible to detect errors in the correct availability of the neonatal stabilization areas and improved their preparation by preventing errors from being perpetuated over time. KEY POINTS: · RRTSAs are a tool for improving clinical safety.. · The use of RRTSAs in perinatal care is very uncommon.. · RRTSAs improve the preparation of newborn CPR areas..
