RESUMEN

Objetivo: estimar a prevalência de nascimento prematuro em gestantes infectadas pela Covid-19, comparar índices de prematuridade entre infectadas e não infectadas e elucidar fatores associados à prematuridade. Métodos: coorte retrospectiva, com coleta de dados por inquérito online, de abril a dezembro de 2022, com mulheres que estiveram gestantes durante a pandemia, com acesso à internet, idade superior a 18 anos e que preencheram o primeiro inquérito online. Protocolo de pesquisa aprovado pelo Comitê de Ética. Resultados: primeiro inquérito respondido por 304 gestantes/puérperas, e o segundo por 82 (27%), compondo a amostra final. O índice de prematuridade no primeiro inquérito foi de 7,2% (n=14), já no segundo, 8,5% (n=7). A infecção pela Covid-19 não foi associada à prematuridade. A prematuridade associou-se a baixo peso, à necessidade de internação em centros de terapia intensiva neonatal e internações após o nascimento. Conclusão: a infecção pela Covid-19 não influenciou no aumento de nascimentos prematuros.


Objective: to estimate the prevalence of preterm birth in pregnant women infected with Covid-19, compare prematurity rates between infected and non-infected, and elucidate factors associated with prematurity. Methods: a retrospective cohort study was conducted using online survey data collected from April to December 2022, involving women who were pregnant during the pandemic, had internet access, were over 18 years old, and completed the initial online survey. The research protocol was approved by the Ethics Committee. Results: the initial survey was completed by 304 pregnant/postpartum women, and the follow-up survey by 82 (27%), comprising the final sample. The preterm birth rate in the initial survey was 7.2% (n=14), and in the follow-up survey, it was 8.5% (n=7). Covid-19 infection was not associated with prematurity. Prematurity was associated with low birth weight, the need for neonatal intensive care unit admission, and postnatal hospitalizations. Conclusion: Covid-19 infection did not influence an increase in preterm births.

RESUMEN

Neonatal stress affects psychological and physiological development and may be associated with affective disorders. The aim was to examine the effects of double neonatal stress (DNS) - a combination of limited bedding and nesting (LBN) and repeated maternal separation (MS) - on the oestrous cycle and sexual behaviour of adult female rats. LBN was achieved by removing part of the wood shavings from the boxes. In the control group, each box was lined with 100 g of wood shavings, while in the experimental group there were only 10 g of wood shavings. MS was performed from P1 (P0 = day of birth) to P15. At P90, the sexual response of females in oestrus was evaluated. Statistical analysis was performed using two-way analysis of variance followed by Tukey's test. The size and profile of the oestrous cycle and the sexual behaviour of female rats submitted to the DNS were considered, as well as the influence of female behaviour on the sexual response of male rats. Female rats submitted to DNS showed a reduction in the lordosis quotient, suggesting a reduction in female receptivity. These rats also showed a reduction in the number of hops and darts, the number of ear wiggles, and the genital exploration time rate, suggesting a reduction in proceptivity. The males that interacted with the females of the DNS group showed a reduction in intromission ratio. Experimental model that mimics neonatal factors that affect adult female sexual response will allow more effective interventions to prevent and treat such changes. In addition, analysis of the female sexual response makes it possible to assess the general state of health and quality of life. In female rats, DNS exerted inhibitory effects on sexual behaviour. LBN was probably the most important factor. In conclusion, combating childhood poverty can be a key measure to prevent problems in the sex life of adults and improve overall health.

RESUMEN

Lipophosphoglycan (LPG) is an important Leishmania virulence factor. It is the most abundant surface glycoconjugate in promastigotes, playing an important role in the interaction with phagocytic cells. While LPG is known to modulate the macrophage immune response during infection, the activation mechanisms triggered by this glycoconjugate have not been fully elucidated. This work investigated the role that LPGs purified from two strains of Leishmania major (FV1 and LV39) play in macrophage activation, considering the differences in their biochemical structures. Bone marrow-derived macrophages from BALB/c mice were stimulated with 10 µg/mL purified LPG from the LV39 and FV1 strains. We then measured the production of nitric oxide (NO) and cytokines, the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), and the activation of MAPK pathways. LPG from the LV39 strain, which has longer poly-galactosylated side chains, induced a more pro-inflammatory profile than that from the FV1 strain. This included higher production of NO, TNF-α, and PGE2, and increased expression of COX-2 and iNOS. Additionally, the phosphorylation of ERK-1/2 and JNK was elevated in macrophages exposed to LPG from the LV39 strain. No difference in IL-10 production was observed in cells stimulated by both LPG. Thus, intraspecific structural differences in LPG contribute to distinct innate immune responses in macrophages.

RESUMEN

The cultivation of marine shrimp is one of the fastest growing activities in the world. However, the emergence of diseases has resulted in a decrease in production and losses for the sector. Probiotics emerged as an option to the use of antibiotics to control these pathogens. The efficiency of applying this technology depends on the characteristics of the bacterial agents and their bioavailability in the shrimp intestine. The objective is to evaluate the viability and efficiency of bacteria isolated from the digestive tract of healthy crustaceans as probiotic agents in the cultivation of shrimp Litopenaeus vannamei. Eighteen strains of the genus Bacillus belonging to the following species were tested: Bacillus sp., B. cereus, B. thuringiensis, B. circulans, B. megaterium, B. subtilis and B. agaridevorans. Bacterial isolates were subjected to characterization as potential probiotics. The test results were considered satisfactory; thus, the tested strains have potential for use as probiotics in shrimp culture. Treatments that used of the genus Bacillus had reduced growth of the genus Vibrio after infection, both in the intestinal contents and in the intestine. With the results obtained, it can be suggested that further research be carried out on the probiotic potential of Bacillus sp.

RESUMEN

INTRODUCTION: When mental disorders go undetected until later stages, they can result in poorer health outcomes for patients. Primary healthcare (PHC) stands as a strategic setting for the early identification and management of these mental disorders, given its role as the primary care environment for health service users. This scoping review has the objective of mapping and assessing screening instruments validated for mental disorders that are applicable in PHC, particularly regarding their measurement properties. METHODS AND ANALYSIS: This scoping review will include studies that have developed and validated screening instruments for mental disorders in the PHC context, irrespective of the age group. Searches will be conducted in MEDLINE, EMBASE, LILACS, CINAHL and PsycInfo without imposing restrictions on publication status, publication year or language. Additionally, we will scrutinise the references cited in the selected studies. Our inclusion criteria encompass studies examining any measurement property recommended by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) taxonomy. The selection process, data extraction and quality assessment of studies will be performed independently by pairs of reviewers. To evaluate the risk of bias within the selected studies, we will employ the COSMIN Risk of Bias 2 tools. The collected data will undergo analysis using descriptive statistics and will be presented in an evidence gap map format for each specific mental disorder. ETHICS AND DISSEMINATION: The findings from this review will be discussed through deliberative dialogue with stakeholders and disseminated through peer-reviewed publications and conference presentations. The project was approved by the Ethics Committee for Research at the University of Sorocaba (number: 66993323.9.0000.5500). TRIAL REGISTRATION NUMBER: Open Science Framework - 10.17605/OSF.IO/Z6T5M.

RESUMEN

Echocardiography is a reliable and non-invasive method for assessing cardiac structure and function in both clinical and experimental settings, offering valuable insights into disease progression and treatment efficacy. The successful application of echocardiography in murine models of disease has enabled the evaluation of disease severity, drug testing, and continuous monitoring of cardiac function in these animals. However, there is insufficient standardization of echocardiographic measurements for smaller animals. This article aims to address this gap by providing a guide and practical tips for the appropriate acquisition and analysis of echocardiographic parameters in adult rats, which may also be applicable in other small rodents used for scientific purposes, like mice. With advancements in technology, such as ultrahigh-frequency ultrasonic transducers, echocardiography has become a highly sophisticated imaging modality, offering high temporal and spatial resolution imaging, thereby allowing for real-time monitoring of cardiac function throughout the lifespan of small animals. Moreover, it allows the assessment of cardiac complications associated with aging, cancer, diabetes, and obesity, as well as the monitoring of cardiotoxicity induced by therapeutic interventions in preclinical models, providing important information for translational research. Finally, this paper discusses the future directions of cardiac preclinical ultrasound, highlighting the need for continued standardization to advance research and improve clinical outcomes to facilitate early disease detection and the translation of findings into clinical practice.

RESUMEN

OBJECTIVE: To investigate, through a systematic review of the literature, whether there are differences in the results of otoacoustic emissions suppression tests in individuals with and without central auditory processing disorder. METHODS: Searches were carried out in the scientific databases Latin American and Caribbean Health Sciences Literature, PubMed, Scientific Electronic Library Online, Web of Science, Scopus, Science Direct and Cochrane, as well as the databases of gray literature British Library, OpenGrey.eu and Object View and Interaction Design. A systematic review of the literature was carried out, with the descriptors otoacoustic emissions and auditory perceptual disorders and their synonyms, combined by the Boolean operators AND and OR. The reading of the studies was done by peers independently and in case of disagreement in the inclusion of studies, a third researcher was consulted. Original cross-sectional articles with a comparison group that suppressed transient evoked otoacoustic emissions in individuals with and without central auditory processing disorder were included. RESULTS: Seven studies that evaluated children aged between 7 and 14 years old were included, with methodological variability in the performance and analysis of the exam, the contralateral noise was the most used to elicit suppression. In only three studies did the group with central auditory processing disorder show lower suppression values, however the meta-analysis shows significant differences between the groups, with lower suppression values in the study groups. CONCLUSION: This study points the need for a protocol that standardizes the measurement of OAE suppression and its findings, aiming to reduce the inclusion of results unrelated to the olivocochlear system.

RESUMEN

The control of microbiologically influenced corrosion (MIC) challenges the oil exploration sector. The MIC results from electrochemical reactions facilitated by microorganisms such as sulfate-reducing bacteria (SRB), which adhere to the surface of the ducts forming biofilms. SRB uses sulfate as the final electron acceptor, resulting in hydrogen sulfide as the final product, a highly reactive corrosive, and toxic compound. Due to the high diversity of the SRB group, this study evaluated the effect of an Escherichia coli phage, with biofilm degrading enzymes, in preventing biofilm formation by microbial consortium P48SEP and reducing H2S production in a complex SRB community. Three phage concentrations were evaluated (104, 108 and 1012 UFP/ml). High and medium phage concentrations prevented biofilm development, as evidenced by scanning electron microscopy, chemical analysis, and cell counts. In addition, the virus altered the expression pattern of some bacterial genes and the relative abundance of proteins related to biofilm formation and cell stress response. Using a complex culture formed mainly by SRB, it was possible to observe the bacterial growth, H2S, and metabolic activity reduction after the phage was added. This study shows for the first time the ability of an E. coli-infecting phage to prevent the biofilm formation of an SRB consortium and infect and replicate at high concentrations on the non-specific host. This new finding turns the use of non-specific phages a promising alternative for the control of biocorrosion in oil and gas installations, on the other side, alert to the use of large concentration of phages and the influence on bacterial groups with geological importance, opening a research field in phage biology.

RESUMEN

Despite increasing knowledge about small extracellular vesicle (sEV) composition and functions in cell-cell communication, the mechanism behind their biogenesis remains unclear. Here, we reveal for the first time that sEV biogenesis and release into the microenvironment are tightly connected with another important organelle, Lipid Droplets (LDs). The correlation was observed in several human cancer cell lines as well as patient-derived colorectal cancer stem cells (CR-CSCs). Our results demonstrated that external stimuli such as radiation, pH, hypoxia or lipid-interfering drugs, known to affect the number of LDs/cell, similarly influenced sEV secretion. Importantly, through multiple omics data, at both mRNA and protein levels, we revealed RAB5C as a potential important molecular player behind this organelle connection. Altogether, the potential to fine-tune sEV biogenesis by targeting LDs could significantly impact the amount, cargos and properties of these sEVs, opening new clinical perspectives.

RESUMEN

Many expectant mothers use CBD to alleviate symptoms like nausea, insomnia, anxiety, and pain, despite limited research on its long-term effects. However, CBD passes through the placenta, affecting fetal development and impacting offspring behavior. We investigated how prenatal CBD exposure affects the insular cortex (IC), a brain region involved in emotional processing and linked to psychiatric disorders. The IC is divided into two territories: the anterior IC (aIC), processing socioemotional signals, and the posterior IC (pIC), specializing in interoception and pain perception. Pyramidal neurons in the aIC and pIC exhibit sex-specific electrophysiological properties, including variations in excitability and the excitatory/inhibitory balance. We investigated IC's cellular properties and synaptic strength in the offspring of both sexes from mice exposed to low-dose CBD during gestation (E5-E18; 3 mg/kg, s.c.). Prenatal CBD exposure induced sex-specific and territory-specific changes in the active and passive membrane properties, as well as intrinsic excitability and the excitatory/inhibitory balance, in the IC of adult offspring. The data indicate that in utero CBD exposure disrupts IC neuronal development, leading to a loss of functional distinction between IC territories. These findings may have significant implications for understanding the effects of CBD on emotional behaviors in offspring.

RESUMEN

Resumo O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas. A variável peso apresentou qualidade satisfatória no Vivaleite e insatisfatória no Sisvan.


Abstract This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN.

RESUMEN

BACKGROUND: Several ablation confirmation software methods for minimum ablative margin assessment have recently been developed to improve local outcomes for patients undergoing thermal ablation of colorectal liver metastases. Previous assessments were limited to single institutions mostly at the place of development. The aim of this study was to validate the previously identified 5 mm minimum ablative margin (A0) using autosegmentation and biomechanical deformable image registration in a multi-institutional setting. METHODS: This was a multicentre, retrospective study including patients with colorectal liver metastases undergoing CT- or ultrasound-guided microwave or radiofrequency ablation during 2009-2022, reporting 3-year local disease progression (residual unablated tumour or local tumour progression) rates by minimum ablative margin across all institutions and identifying an intraprocedural contrast-enhanced CT-based minimum ablative margin associated with a 3-year local disease progression rate of less than 1%. RESULTS: A total of 400 ablated colorectal liver metastases (median diameter of 1.5 cm) in 243 patients (145 men; median age of 62 [interquartile range 54-70] years) were evaluated, with a median follow-up of 26 (interquartile range 17-40) months. A total of 119 (48.9%) patients with 186 (46.5%) colorectal liver metastases were from international institutions B, C, and D that were not involved in the software development. Three-year local disease progression rates for 0 mm, >0 and <5 mm, and 5 mm or larger minimum ablative margins were 79%, 15%, and 0% respectively for institution A (where the software was developed) and 34%, 19%, and 2% respectively for institutions B, C, and D combined. Local disease progression risk decreased to less than 1% with an intraprocedurally confirmed minimum ablative margin greater than 4.6 mm. CONCLUSION: A minimum ablative margin of 5 mm or larger demonstrates optimal local oncological outcomes. It is proposed that an intraprocedural minimum ablative margin of 5 mm or larger, confirmed using biomechanical deformable image registration, serves as the A0 for colorectal liver metastasis thermal ablation.

RESUMEN

OBJECTIVE: To evaluate efficacy, safety, and adherence to using adjustable compression wraps (ACWs) for upper limb volume control in women with breast cancer-related lymphedema. DESIGN AND SETTING: Randomized controlled trial at a reference hospital for breast cancer treatment in Brazil. PARTICIPANTS: Women in control phase of the breast cancer-related lymphedema. INTERVENTIONS: Compared use of ACWs versus compressive mesh. MAIN MEASURES: Evaluated before treatment, at 30 days, and 6 months after initiating therapy. The primary outcome was the change in excess limb volume. Secondary outcomes included adherence, incidence of adverse events, functionality, quality of life, and hand grip. Statistical analysis involved calculating the effect size (ES) with a 95% confidence interval. RESULTS: Were included 71 women with mean excess limb volume of 321.79 mL (±194.98). In the 30-day analysis (Time 1), a reduction of 37.6 mL in volume was observed only in the ACW group (p = .041, ES 0.20), with improved functionality (p = .013, ES 0.22). In the six months analysis (Time 2), the compressive mesh group increased by 2.48% in volume (p = .023, ES 0.26) and demonstrated improvement functionality (p = .036, ES 0.27). Mild adverse events and satisfactory adherence were observed. However, in the intergroup comparison, no statistically significant difference was observed for any evaluated outcome-excess volume, incidence of adverse events, adherence, hand grip, quality of life, and functionality between the groups (p > .05) at both times. CONCLUSIONS: Both compression therapies achieved satisfactory adherence, were safe, effective and equivalent for controlling limb volume in breast cancer-related lymphedema.

RESUMEN

OBJECTIVE: To map evidence on nursing care for women with HELLP syndrome. METHOD: A scoping review with searches carried out in May 2023, independently, in the PubMed/MEDLINE, LILACS, Scopus, EMBASE, Web of Science, CINAHL, CAPES Theses and Dissertations Catalog and Cochrane Library databases, correlating the descriptors HELLP Syndrome, Nursing Care and Obstetric Nursing and its synonyms, without delimitation of time and language. Selection was carried out by three researchers independently and resolved by consensus. RESULTS: Of the 129 studies, ten were selected, which made up the final sample. The studies date from 2004 to 2022, with a predominance of English language and clinical case studies. A greater occurrence of the syndrome was observed in second-time pregnant women in the second decade of life, with a gestational age from 32 weeks, which resulted in an emergency cesarean section, and all newborns were discharged accompanied by their mothers. Studies that described nursing diagnoses and focused on nursing care were retrieved. From the review, 39 nursing care were identified. CONCLUSION: This review pointed out the magnitude of the syndrome, however with a lack of studies.

RESUMEN

This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN.


O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas. A variável peso apresentou qualidade satisfatória no Vivaleite e insatisfatória no Sisvan.

RESUMEN

BACKGROUND: Viral respiratory infections may precipitate type 1 diabetes (T1D). A possible association between the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19, and the incidence of T1D is being determined. This study was carried out using Portuguese registries, aiming at examining temporal trends between COVID-19 and T1D. METHODS: Hospital data, comparing the incidence before and during the COVID-19 pandemic, from children and young adults diagnosed with new-onset T1D, was acquired beginning in 2017 and until the end of 2022. Data was obtained from nine different Portuguese hospital units. The impact of the COVID-19 pandemic, beginning in March 2020, was assessed comparing the annual numbers of new-onset T1D cases. The annual median levels of glucose, glycated hemoglobin (HbA1c) and fasting C-peptide at T1D diagnosis were compared. The annual number of diabetic ketoacidosis (DKA) episodes among new T1D cases was also assessed at two centers. RESULTS: In total, data from 574 newly diagnosed T1D patients was analyzed, including 530 (92.3%) children. The mean ages for child and adult patients were 9.1 (SD 4.4) and 32.8 (SD 13.6) years, respectively. 57.8% (331/573) were male, one patient had unknown sex. The overall median (25-75 percentiles) levels of glucose, HbA1c and fasting C-peptide at diagnosis were 454 mg/dL (356-568), 11.8% (10.1-13.4) and 0.50 µg/L (0.30-0.79), respectively. DKA at T1D diagnosis was present in 48.4% (76/157). For eight centers with complete 2018 to 2021 data (all calendar months), no overall significant increase in T1D cases was observed during the COVID-19 pandemic, i.e. 90 cases in 2018, 90 cases in 2019, 112 in 2020 and 100 in 2021 (P for trend = 0.36). Two of the centers, Faro (CHUA) and Dona Estefânia (CHULC) hospitals, did however see an increase in T1D from 2019 to 2020. No significant changes in glucose (P = 0.32), HbA1c (P = 0.68), fasting C-peptide (P = 0.20) or DKA frequency (P = 0.68) at the time of T1D diagnosis were observed over the entire study period. CONCLUSION: The T1D incidence did not increase significantly, when comparing the years before and during the COVID-19 pandemic, nor did key metabolic parameters or number of DKA episodes change.

RESUMEN

Many expectant mothers use CBD to alleviate symptoms like nausea, insomnia, anxiety, and pain, despite limited research on its long-term effects. However, CBD passes through the placenta, affecting fetal development and impacting offspring behavior. We investigated how prenatal CBD exposure affects the insular cortex (IC), a brain region involved in emotional processing and linked to psychiatric disorders. The IC is divided into two territories: the anterior IC (aIC), processing socioemotional signals, and the posterior IC (pIC), specializing in interoception and pain perception. Pyramidal neurons in the aIC and pIC exhibit sex-specific electrophysiological properties, including variations in excitability and the excitatory/inhibitory balance. We investigated IC's cellular properties and synaptic strength in the offspring of both sexes from mice exposed to low-dose CBD during gestation (E5-E18; 3mg/kg, s.c.). Prenatal CBD exposure induced sex-specific and territory-specific changes in the active and passive membrane properties, as well as intrinsic excitability and the excitatory/inhibitory balance, in the IC of adult offspring. The data indicate that in-utero CBD exposure disrupts IC neuronal development, leading to a loss of functional distinction between IC territories. These findings may have significant implications for understanding the effects of CBD on emotional behaviors in offspring.
