Abstract
BACKGROUND No evidence-based therapy for borderline personality disorder (BPD) exhibits a clear superiority. However, BPD is highly heterogeneous, and different patients may specifically benefit from the interventions of a particular treatment. METHODS From a randomized trial comparing a year of dialectical behavior therapy (DBT) to general psychiatric management (GPM) for BPD, long-term (2-year-post) outcome data and patient baseline variables (n = 156) were used to examine individual and combined patient-level moderators of differential treatment response. A two-step bootstrapped and partially cross-validated moderator identification process was employed for 20 baseline variables. For identified moderators, 10-fold bootstrapped cross-validated models estimated response to each therapy, and long-term outcomes were compared for patients randomized to their model-predicted optimal v. non-optimal treatment. RESULTS Significant moderators surviving the two-step process included psychiatric symptom severity, BPD impulsivity symptoms (both GPM > DBT), dependent personality traits, childhood emotional abuse, and social adjustment (all DBT > GPM). Patients randomized to their model-predicted optimal treatment had significantly better long-term outcomes (d = 0.36, p = 0.028), especially if the model had a relatively stronger (top 60%) prediction for that patient (d = 0.61, p = 0.004). Among patients with a stronger prediction, this advantage held even when applying a conservative statistical check (d = 0.46, p = 0.043). CONCLUSIONS Patient characteristics influence the degree to which they respond to two treatments for BPD. Combining information from multiple moderators may help inform providers and patients as to which treatment is the most likely to lead to long-term symptom relief. Further research on personalized medicine in BPD is needed.

Abstract
BACKGROUND Overlap in symptom domains particularly in the field of impulsivity and emotional dysregulation in attention deficit hyperactivity disorder (ADHD) and borderline personality disorder (BPD) have stimulated further research activities since our last review from 2014. MAIN BODY Disentangling features of impulsivity in ADHD and BPD revealed that impulsivity is a feature of both disorders with patients suffering from both ADHD and BPD having highest impulsivity ratings. BPD individuals have more problems using context cues for inhibiting responses and their impulsivity is stress-dependent, whereas ADHD patients have more motor impulsivity and therefore difficulties interrupting ongoing responses. For emotion regulation difficulties the ranking order ranges from ADHD to BPD to the comorbid condition, again with the patients suffering from both, ADHD and BPD, having the most pronounced emotion regulation problems. Environmental influences namely adverse childhood events were shown to be linked to both ADHD and BPD. Traumatic experiences seem independently linked to impulsivity features. Thus, some authors point to the risk of misdiagnosis during childhood and the necessity to screen for traumatic experiences in both patient groups. Genetic research confirmed genetic overlap of BPD with bipolar disorder (BD) and schizophrenic disorders, as well as genetic overlap of BD and ADHD. A population-based study confirmed the high co-occurrence and familial co-aggregation of ADHD and BPD. Interesting questions in the field of gene-environment-interactions are currently dealt with by genetic and epigenetic research. Few studies have investigated treatment strategies for the comorbid condition, though the issue is highly important for the management of patients suffering from both disorders and presenting with the highest symptom scores. CONCLUSION Research on the different impulsivity features might point to a necessity of disorder-specific treatment strategies in the field of impulse control. Future research is needed to base treatment decisions for the comorbid condition on an evidence basis.

Abstract
Background Less invasive surfactant administration (LISA) is the preferred mode of surfactant administration for spontaneously breathing preterm babies supported by noninvasive ventilation (NIV). Objective The aim of this study was to determine whether LISA on the neonatal unit or in the delivery suite was associated with reduced rates of bronchopulmonary dysplasia (BPD) or the need for intubation, or lower durations of invasive ventilation and length of hospital stay (LOS). Methods A historical comparison was undertaken. Each "LISA" infant was matched with two infants (controls) who did not receive LISA. Results The 25 LISA infants had similar gestational ages and birth weights to the 50 controls (28 [25.6-31.7] weeks vs. 28.5 [25.4-31.9] weeks, p = 0.732; 1,120 (580-1,810) g vs. 1,070 [540-1,869] g, p = 0.928), respectively. LISA infants had lower requirement for intubation (52 vs. 90%, p < 0.001), shorter duration of invasive ventilation (median 1 [0-35] days vs. 6 [0-62] days p = 0.001) and a lower incidence of BPD (36 vs. 64%, p = 0.022). There were no significant differences in duration of NIV (median 26 [3-225] vs. 23 [2-85] days, p = 0.831) or the total LOS (median 76 [24-259] vs. 85 [27-221], p = 0.238). Conclusion LISA on the neonatal unit or the delivery suite was associated with a lower BPD incidence, need for intubation, and duration of invasive ventilation.

Abstract
Bronchopulmonary dysplasia (BPD), also known as neonatal chronic lung disease, is
an important cause of respiratory illness in preterm newborns that results in
significant morbidity and mortality. Long noncoding RNAs (lncRNAs) have been
discovered with many biological functions. However, the role of lncRNAs in the
pathogenesis of BPD remains poorly understood. Here, we established a mouse lung
injury model that mimicked human BPD. Subsequently, we found the lncRNA H19
expression level was significantly increased in BPD compared with normal lung
tissues using quantitative real-time polymerase chain reaction. Next, we
observed that overexpression of lncRNA H19 enhanced mitogen-activated protein
kinase (MAPK) signaling pathway. In addition, we also found that dysfunction of
lncRNA H19 altered the expression of inflammatory factors. Thus, our study
validates that lncRNA H19 contributes to the progression of BPD by regulating
MAPK signaling pathway, which could be used as a potential target for treating
BPD.

Abstract
AIM Several prediction models have been introduced to identify young people at greatest risk of transitioning to psychosis. To date, none has examined the possibility of developing a clinical prediction model of outcomes other than transition. The aims of this study were to examine the association between baseline clinical predictors and outcomes including, but not limited to, transition to psychosis in young people at risk for psychosis, and to develop a prediction model for these outcomes. METHODS Several evidence-based variables previously associated with transition to psychosis and some important clinical comorbidities experienced by ultra-high risk (UHR) individuals were identified in 202 UHR individuals. Secondary analysis of the Neurapro clinical trial were conducted to investigate the associations between these variables and favourable (remission and recovery) or unfavourable (transition to psychosis, no remission, any recurrence and relapse) clinical outcomes. Logistic regression, best subset selection, Akaike Information Criterion and receiver operating characteristic curves were used to seek the best prediction model for clinical outcomes from all combinations of possible predictors. RESULTS When considered individually, only higher general psychopathology levels (P = .023) was associated with the unfavourable outcomes. Prediction models suggest that general psychopathology and functioning are predictive of unfavourable outcomes. CONCLUSION The predictive performance of the resulting models was modest and further research is needed. Nonetheless, when designing early intervention centres aiming to support individuals in the early phases of a mental disorder, the proper assessment of general psychopathology and functioning should be considered in order to inform interventions and length of care provided.

Abstract
(1) Background: Dialectical Behaviour Therapy (DBT) is the recommended treatment for Borderline Personality Disorder (BPD) symptoms in adults, however, research investigating the effectiveness of DBT for adolescents is limited. The present study explores the experiences of young people and their parents/carers of a DBT service using qualitative methodology. (2) Methods: Young people and their parents/carers, who completed DBT within the National and Specialist Child and Adolescent Mental Health DBT Service based at the Maudsley Hospital in London, were asked questions regarding their experience of the service. Data was collected from young people who completed treatment between July 2019 and July 2020 (n = 18) and their parents and carers (n = 7). (3) Results: Amongst young people, the themes identified were: a new way of living, better understanding of self, new skills, person-centred approach, and relationships with others. Parent and carer interviews revealed themes of improved relationships, feeling supported, improved quality of life, and time/timing. (4) Conclusions: Young people reported improvements in emerging BPD symptomology after completing DBT. Parents and carers reported improvements in their young person and families since starting DBT. A longer DBT programme, earlier DBT intervention, and the time-consuming nature of DBT were highlighted as areas for improvement.

Abstract
Major depressive disorder (MDD) and bipolar disorder (BPD) are among the most debilitating mental conditions. Diagnostic criteria for MDD include psychological and physical symptoms, such as low mood and changes in appetite or sleep, respectively. BPD in addition to periods of depression represents episodes of mania or hypomania, and elevation in mood and energy levels are associated with this condition. Dysregulation in adult neurogenesis and myelination have been reported in psychiatric disorders. As a key factor in neurogenesis, it was hypothesized that Myt1 gene expression may be altered in these conditions. Using Real-time PCR, Myt1 expression level in 100 MDD patients and 100 BPD patients, compared with healthy control (HC) individuals was evaluated. Results demonstrate significant downregulation of Myt1 in MDD and BPD. Logistic regression analysis and binary classification evaluation reveal potential risk factor and biomarker characteristics of Myt1, respectively. Moreover, forward and backward digit span results denote a significant reduction in the function of working memory (WM) of MDD and BPD subjects. Correlation analysis revealed a significant association between Myt1 downregulation and WM disruption in the affected individuals. In conclusion, due to its altered role in neurogenesis, downregulation of Myt1 can be associated with the pathology of MDD and BPD.

Abstract
BACKGROUND Mentalizing, the ability to understand the self and others as well as behaviour in terms of intentional mental states, is impaired in Borderline Personality Disorder (BPD). Evidence for mentalizing deficits in other mental disorders, such as depression, is less robust and these links have never been explored while accounting for the effects of BPD on mentalizing. Additionally, it is unknown whether BPD symptoms might moderate any relationship between depressive symptoms and mentalizing. METHODS Using multivariate regression modelling on cross-sectional data obtained from a sample of 274 participants recruited from clinical settings, we investigated the association between mentalizing impairment and depression and examined whether this was moderated by the presence and number of concurrent BPD symptoms, while adjusting for socio-demographic confounders. RESULTS Impaired mentalizing was associated with depressive symptoms, after adjustment for socio-demographic confounders and BPD symptoms (p = 0.002, β = - 0.18). BPD symptoms significantly moderated the association between impaired mentalizing and depressive symptoms (p = 0.003), with more severe borderline symptoms associated with a stronger effect of poor mentalization on increased depressive symptoms. CONCLUSION Mentalizing impairments occur in depression even after adjusting for the effect of BPD symptoms. Our findings help further characterise mentalizing impairments in depression, as well as the moderating effect of BPD symptoms on this association.. Further longitudinal work is required to investigate the direction of association.

Abstract
BACKGROUND AND PURPOSE Bronchopulmonary dysplasia (BPD) is the most prevalent chronic paediatric lung disease and is linked to the development of chronic obstructive pulmonary disease. MicroRNA-based regulation of type II alveolar epithelial cell (T2AEC) proliferation and apoptosis is an important factor in the pathogenesis of BPD and warrants further investigation. EXPERIMENTAL APPROACH Two murine models of hyperoxic lung injury (with or without miR-342-5p or Sprouty-related, EVH1 domain-containing protein 3 [Spred3] modulation) were employed: a hyperoxia-induced acute lung injury model (100% O2 on postnatal days 1-7) and the BPD model (100% O2 on postnatal days 1-4, followed by room air for 10 days). Tracheal aspirate pellets from healthy control and moderate/severe BPD neonates were randomly selected for clinical miR-342-5p analysis. KEY RESULTS Hyperoxia decreased miR-342-5p levels in primary T2AECs, MLE12 cells and neonatal mouse lungs. Transgenic miR-342 overexpression in neonatal mice ameliorated survival rates and improved the BPD phenotype and BPD-associated pulmonary arterial hypertension (PAH). T2AEC-specific miR-342 transgenic overexpression, as well as miR-342-5p mimic therapy, also ameliorated the BPD phenotype and associated PAH. miR-342-5p targets the 3'UTR of the Raf1 regulator Spred3, inhibiting Spred3 expression. Treatment with recombinant Spred3 exacerbated the BPD phenotype and associated PAH. Notably, miR-342-5p inhibition under room air conditions did not mimic the BPD phenotype. Moderate/severe BPD tracheal aspirate pellets exhibited decreased miR-342-5p levels relative to healthy control pellets. CONCLUSION AND IMPLICATIONS These findings suggest that miR-342-5p mimic therapy may show promise in the treatment or prevention of BPD.

Abstract
Impulsivity is a characteristic syndromal and neurobehavioral feature of borderline personality disorder (BPD). Research suggests an important interaction between high negative emotions and low behavioral inhibition in BPD. However, knowledge about the generalizability across stimulus categories and diagnosis specificity is limited. We investigated neural correlates of hypothesized impaired response inhibition of BPD patients to negative, positive and erotic stimuli, by comparing them to non-patients and cluster-C personality disorder patients. During fMRI scanning, 53 BPD patients, 34 non-patients and 20 cluster-C personality disorder patients completed an affective go/no-go task, including social pictures. BPD patients showed more omission errors than non-patients, independent of the stimulus category. Furthermore, BPD patients showed higher activity in the inferior parietal lobule and frontal eye fields when inhibiting negative versus neutral stimuli. Activity of the inferior parietal lobule correlated positively with the BPD checklist subscale impulsivity. When inhibiting emotional stimuli, BPD patients showed an altered brain activity in the inferior parietal lobe and frontal eye fields, whereas previously shown dysfunctional prefrontal activity was not replicated. BPD patients showed a general responsivity across stimulus categories in the frontal eye fields, whereas effects in the inferior parietal lobe were specific for negative stimuli. Results of diagnosis specificity support a dimensional rather than a categorical differentiation between BPD and cluster-C patients during inhibition of social emotional stimuli. Supported by behavioral results, BPD patients showed no deficiencies in emotionally modulated response inhibition per se but the present findings rather hint at attentional difficulties for emotional information.

Abstract
BACKGROUND Many individuals with borderline personality disorder (BPD) perceive emotional expressions in faces intended to convey no emotion and display a heightened sensitivity to facial expressions conveying threat, such as fear. In BPD, the amygdala activates in response to ambiguous and threatening facial expressions, although the differential sensitivity of this brain region to higher and lower intensities of fearful expressions and the relationship of this neural activity to personality impairments have not yet been investigated. METHODS In the present study, we examined brain activation during an implicit facial emotion task with neutral faces and fearful expressions displayed at 50% and 100% intensity in patients with BPD (n=45) and healthy controls (HC; n=25). RESULTS On neutral faces, higher brain activation was found in BPD compared to HC in the right temporal pole, amygdala, hippocampus, pallidum, and orbitofrontal cortex, whereas no significant whole-brain group differences were observed for either intensity of fearful expressions. A region-of-interest analysis focused on the amygdala-hippocampal complex showed greater activation for neutral and 50%-intensity fearful faces in BPD. Severity of personality impairment in the domains of empathy and identity were associated with higher precuneus activity during neutral and 100%-fearful face processing. LIMITATIONS Brain activation differences of this naturalistic severely ill inpatient sample may be influenced by comorbid Axis-I disorders often seen in samples of BPD. CONCLUSIONS These findings suggest a heightened amygdala-hippocampal response to neutral faces and moderate-intensity fearful expressions in BPD, while self and interpersonal impairments are associated with task-based activations in regions implicated in self-referential processes.

Abstract
Borderline personality disorder (BPD) is underdiagnosed in clinical practice. One approach towards improving diagnostic detection is the use of screening questionnaires. It is important for a screening test to have high sensitivity because the more time-intensive/expensive follow-up diagnostic inquiry will presumably only occur in patients who are positive on the initial screen. The most commonly studied self-report scale specific for BPD is the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD). We summarize the performance of the scale across studies, examine the performance of the scale using different cutoff scores, and highlight the approach used by investigators in recommending a cutoff score. Most studies of the scale have taken a case-finding approach in deriving the cutoff score on the scale instead of a screening approach. For the purposes of screening, it may be more appropriate for the cutoff score on the MSI-BPD to be less than the currently recommended cutoff of 7.

Abstract
Bronchopulmonary dysplasia (BPD) is the most common chronic lung disease (CLD) in premature infants. The present study was designed to elucidate the regulation of miRNA-547-3p on adrenomedullin (ADM) during the pathogenesis of BPD. We used Agilent Human 4x44K Gene Expression Microarrays v2 and miRCURY LNA™ microRNA Array to identify the differently expressed miRNA and its potential target genes, and certified them again by luciferase reporter gene analysis. We only retained target genes that met the following two conditions: first, coexisting in two databases, and second, expressing differences, and then identifying target genes by luciferase reporter gene analysis. Thus, we selected miRNA-574-3p and its target gene ADM for further research. We used real-time q-PCR to determine the expression of miRNA-574-3p and its target gene ADM in premature infants with BPD. We used microarray expression to analyze BPD samples and non-BPD samples and found that there were 516 differently expressed probes between them. The 516 differently expressed probes included 408 up-regulated probes and 108 down-regulated probes. The blood samples of BPD infants were detected by real-time q-PCR and found that the expression of miRNA-574-3p was decreased, while the expression of ADM was significantly increased. Luciferase reporter gene analysis showed that hsa-miR-574-3p can regulate the expression of luciferase with ADM 3′UTR, and decrease it by 61.84%. It has been reported in the literature that ADM can protect the premature infants with BPD. The target gene ADM of miRNA-574-3p may contribute to the prevention and treatment of BPD.

Abstract
Extremely premature infants have demonstrated increased survival due to advancements in care. This population is at risk for decreased lung function that persists into adolescence. It is important for clinicians to consider this history when treating and assessing such patients who contract SARS-CoV-2 respiratory infection. A 17-year-old, former premature infant of 23 weeks gestation with BPD presented to the pediatric emergency department for evaluation of hypoxia and increased work of breathing in the setting of SARS-CoV-2 infection. He was managed aggressively with early noninvasive respiratory support, Remdesevir, systemic steroids, and convalescent plasma. Utilization of aggressive medical therapies early in the hospital course assisted in preventing intubation and mechanical ventilation for this patient. While there are studies examining the severity of SARS-CoV-2 infection in premature infants, there is a paucity of data on this vulnerable group as they age into adolescence. More studies are needed to assess the severity of illness and optimal management of this population.

Abstract
Despite major advances in neonatal intensive care, infants born at extremely low birth weight still face an increased risk for chronic illness that may persist into adulthood. Pulmonary, retinal, and neurocognitive morbidities associated with preterm birth remain widespread despite interventions designed to minimize organ dysfunction. The design of therapeutic applications for preterm pathologies sharing common underlying triggers, such as fluctuations in oxygen supply or in the inflammatory state, requires alternative strategies that promote anti-inflammatory, pro-angiogenic, and trophic activities—ideally as a unitary treatment. Mesenchymal stem/stromal cell-derived extracellular vesicles (MEx) possess such inherent advantages, and they represent a most promising treatment candidate, as they have been shown to contribute to immunomodulation, homeostasis, and tissue regeneration. Current pre-clinical studies into the MEx mechanism of action are focusing on their restorative capability in the context of preterm birth-related pathologies, albeit not always with a multisystemic focus. This perspective will discuss the pathogenic mechanisms underlying the multisystemic lesions resulting from early-life disruption of normal physiology triggered by high oxygen exposures and pro-inflammatory conditions and introduce the application of MEx as immunomodulators and growth-promoting mediators for multisystem therapy.

Abstract
BACKGROUND Less invasive surfactant replacement therapy (SRT) methods have been linked to better respiratory outcomes. The primary aim of this study was to determine if Less Invasive Surfactant Administration (LISA) altered the rate of bronchopulmonary dysplasia (BPD) in preterm infants. Secondary objectives were to determine if LISA compared to Intubation Surfactant Extubation (InSurE) resulted in different respiratory outcomes and hospital course. METHODS In this retrospective chart review, outcomes were compared in two preterm infant groups (25-32 weeks gestation). Infants in Group 1 received surfactant replacement therapy (SRT) via InSurE method, while infants in Group 2 received SRT via LISA method. RESULTS Regardless of SRT method utilized, there were no significant differences in rates of BPD between the two groups in infants born at 25-32 weeks gestation (30.6% vs 33.3%; P = 0.47). CONCLUSIONS Despite using LISA method rather than InSurE for SRT, premature infants continue to be at high risk for BPD. LISA shows promise as a safe, noninvasive SRT alternative to invasive methods like InSurE.

Abstract
Shame has been found to be a core feature of borderline personality disorder (BPD). To date, there is no existing systematic review or meta-analysis examining shame in individuals with BPD as compared to healthy controls (HCs). A meta-analysis of 10 studies comparing reported shame in BPD patients to HCs was carried out. Demographic and clinical moderator variables were included to see if they have a relationship with the effect size. Results showed that those with BPD had more reported shame than healthy controls. In addition, in BPD patients and HCs, higher education level was related to lower reported shame. In HCs, it was found that those who were younger reported a higher level of shame. Finally, among BPD patients, there was a relationship between levels of reported shame and elevated PTSD symptomatology. These findings emphasize the clinical relevance of shame in individuals with BPD and the need to formulate psychotherapeutic strategies that target and decrease shame.

Abstract
BACKGROUND Asymmetric Dimethyl Arginine (ADMA) is an endogenous inhibitor of nitric oxide synthase (NOS) is important in different diseases characterized by decreased nitric oxide (NO) availability. We aimed to assess the serum ADMA level in preterm infants suffering from respiratory distress syndrome (RDS) and its relationship with pulmonary outcomes. METHODS This prospective study included 50 preterm neonates suffering from RDS aging≤32 weeks and weighing≤1500 gm. Serum ADMA levels were estimated in the 1st and 28th day of life by ELISA, and its correlation with surfactant requirement, duration of ventilation, and development of BPD was assessed. RESULTS Fifty preterm infants with RDS were included, 30 infants were treated with surfactant within 12 hours after birth, the 1stday ADMA level was higher significantly in infants who required surfactant treatment than infants without surfactant treatment, At 36 weeks postmenstrual age, 16 infants were diagnosed with BPD, the 28th day ADMA level was significantly higher in infants with BPD than others without BPD. 1st-day ADMA level was significantly correlated with days on mechanical ventilation but there were no significant correlations between 1st day ADMA and days on CPAP and days on supplemental O2. CONCLUSION Elevated serum ADMA level in preterm neonates with RDS estimated in the 1st and 28th day of life is a good predictor for pulmonary morbidities such as surfactant requirement, duration of mechanical ventilation, and development of BPD.

Abstract
Premature infants, especially those with bronchopulmonary dysplasia (BPD), develop recurrent severe respiratory viral illnesses. We have shown that hyperoxic exposure of immature mice, a model of BPD, increases lung IL-12-producing Clec9a+ CD103+ dendritic cells (DCs), pro-inflammatory responses, and airway hyperreactivity following rhinovirus (RV) infection. However, the requirement for CD103+ DCs and Clec9a, a DAMP receptor that binds necrotic cell cytoskeletal filamentous actin (F-actin), for RV-induced inflammatory responses has not been demonstrated. To test this, 2-day-old C57BL/6J, CD103+ DC-deficient Batf3-/- or Clec9agfp-/- mice were exposed to normoxia or hyperoxia for 14 days. Also, selected mice were treated with neutralizing antibody against CD103. Immediately after hyperoxia, the mice were inoculated with RV intranasally. We found that compared with wild-type mice, hyperoxia-exposed Batf3-/- mice showed reduced levels of IL-12p40, IFN-γ, and TNF-α, fewer IFN-γ-producing CD4+ T cells, and decreased airway responsiveness following RV infection. Similar effects were observed in anti-CD103-treated and Clec9agfp-/- mice. Furthermore, hyperoxia increased airway dead cell number and extracellular F-actin levels. Finally, studies in preterm infants with respiratory distress syndrome showed that tracheal aspirate CLEC9A expression positively correlated with IL12B expression, consistent with the notion that CLEC9A+ cells are responsible for IL-12 production in humans as well as mice. We conclude that CD103+ DCs and Clec9a are required for hyperoxia-induced pro-inflammatory responses to RV infection. In premature infants, Clec9a-mediated activation of CD103+ DCs may promote pro-inflammatory responses to viral infection, thereby driving respiratory morbidity.

Neurodevelopmental outcomes in very preterm infants: The role of severity of Bronchopulmonary Dysplasia. Early Hum Dev 2021; 152:105275. [PMID: 33227635 DOI: 10.1016/j.earlhumdev.2020.105275] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2020] [Revised: 09/17/2020] [Accepted: 11/10/2020] [Indexed: 11/17/2022]
Abstract
OBJECTIVE Bronchopulmonary dysplasia is a chronic respiratory disease that still affects preterm neonates; its association with neurodevelopmental (ND) impairment is already known. Different studies investigated neurodevelopmental outcomes in infants with BPD, often using the old dichotomous definition (BPD vs Non-BPD). This retrospective study aims to evaluate the role of different BPD severity grades on ND outcomes at 24 months of corrected age (CA). METHODS All preterm infants born between 2011 and 2015 in the study hospital with a gestational age (GA) ≤ 30 weeks and discharged from our NICU were included and were divided in infants with and without BPD. Infants with BPD were divided into three severity groups as defined by NICHD/NHLBI Workshop in 2001, and were compared to their Non-BPD peers, matching them according to the same GA and year of birth. At 24 months postmenstrual age, we assessed general outcomes (growth and hospital readmissions) and neurodevelopmental outcomes (motor, developmental and sensory outcomes) with a standardized assessment. RESULTS We enrolled 89 patients affected by BPD of different grades of severity and a control group of 89 preterm infants without BPD. Infants with Moderate and Severe BPD showed a significantly higher corrected odds ratio (OR) for cognitive impairment compared to controls. Within the group of infants without severe disability (regarding Griffiths' scales), infants with Moderate and Severe BPD as well as infants with Mild BPD showed a significantly higher risk of a lower total Developmental Quotient (DQ) score, even after correction for confounding factors. CONCLUSIONS Our study evidenced that not only Severe BPD infants, but also Moderate ones showed a higher risk of overall cognitive impairment at 24 months CA. Within the group of infants without severe disability, also those with Mild BPD had lower Griffiths DQ scores than those without. This would suggest that infants with BPD, regardless of severity, warrant neurodevelopmental follow-up.

Abstract
Psychotherapy is the cornerstone of treatment for borderline personality disorder (BPD) while pharmacotherapy should be considered only as an adjunctive intervention. In clinical practice, however, most of BPD patients only receive medication. The aim of the study is to first describe pharmacological treatment in BPD patients in Italy and secondly to evaluate if comorbidity or illness severity are associated with the prescription of different class compounds. Data on pharmacological treatment and clinical evaluation of 75 BPD patients were collected in 5 clinical settings. The association between comorbidity and medication was assessed. Moreover, we evaluated the association between pharmacotherapy and severity, defined by a cluster analysis aimed at detecting different groups of patients. Most of the participants (82.7%) were characterized by polypharmacy, with a mean of 2.4 medications per person. Interestingly, the prescription didn't seem to depend on/be based on the severity of the disorder and was only partially determined by the presence of comorbidity. In conclusion, our findings are similar to what described in other clinical studies, supporting the idea that medication management for BPD is only partially coherent with international guidelines. This pilot study confirms the need for more rigorous studies to gain greater understanding of this topic and diminish the gap between guidelines and the real clinical world.

Abstract
BACKGROUND It is unknown whether international guidelines on gestational weight gain can be used in pregnancies after bariatric surgery. OBJECTIVES To investigate gestational weight gain, intrauterine growth, and postpartum weight retention in postbariatric women. SETTING 8 Belgian hospitals. METHODS Prospective data from 127 postbariatric pregnancies from September 2014 through October 2018. Patients were grouped according to achievement of 2009 Institute of Medicine (IOM) guidelines. RESULTS In 127 patients with a mean age of 30.2 years (standard deviation [SD], 4.7), the mean gestational weight gain was 12.5 kg (SD, 6.7). Of these patients, 24% (30 of 127) showed insufficient weight gain, 20% (26 of 127) showed adequate weight gain, and 56% (71 of 127) showed excessive weight gain. Of 127 patients, 27 (21%) had small-for-gestational-age infants. This peaked in the group with insufficient weight gain (47%; 95% confidence interval [CI], 29%-65%; P < .001). The prevalence of large-for-gestational-age infants was comparable between groups, although highest in the group with excessive weight gain (0% in those with insufficient weight gain, 4% in those with adequate weight gain, and 8% in those with excessive weight gain). Preterm births were recorded more in patients with insufficient weight gain (23%; 95% CI, 8%-38%; P = .048). The mean amounts of postpartum weight retained were 4.0 kg (SD, 7.4) at 6 weeks and 3.0 kg (SD, 9.1) at 6 months. Weight retention at 6 weeks (7.1 kg; 95% CI, 5.5-8.7; P < .001) and 6 months (8.3 kg; 95% CI, 4.5-12.2; P < .001) was highest in women gaining excessive weight. CONCLUSION Achievement of IOM guidelines is low in postbariatric pregnancies. Insufficient weight gain increases the risk for small-for-gestational-age babies. Excessive weight gain increases weight retention after delivery and could precipitate weight regain. After bariatric surgery, women should be encouraged to achieve IOM recommendations.

Abstract
Regulatory T cells (Tregs) are important for the ontogenetic control of immune activation and tissue damage in preterm infants. However, the role of Tregs for the development of bronchopulmonary dysplasia (BPD) is yet unclear. The aim of our study was to characterize CD4+ CD25+ forkhead box protein 3 (FoxP3)+ Tregs in peripheral blood of well-phenotyped preterm infants (n = 382; 23 + 0 – 36 + 6 weeks of gestational age) with a focus on the first 28 days of life and the clinical endpoint BPD (supplemental oxygen for longer than 28 days of age). In a subgroup of preterm infants, we characterized the immunological phenotype of Tregs (n = 23). The suppressive function of Tregs on CD4+CD25- T cells was compared in preterm, term and adult blood. We observed that extreme prematurity was associated with increased Treg frequencies which peaked in the second week of life. Independent of gestational age, increased Treg frequencies were noted to precede the development of BPD. The phenotype of preterm infant Tregs largely differed from adult Tregs and displayed an overall naïve Treg population (CD45RA+/HLA-DR-/Helios+), especially in the first days of life. On day 7 of life, a more activated Treg phenotype pattern (CCR6+, HLA-DR+, and Ki-67+) was observed. Tregs of preterm neonates had a higher immunosuppressive capacity against CD4+CD25- T cells compared to the Treg compartment of term neonates and adults. In conclusion, our data suggest increased frequencies and functions of Tregs in preterm neonates which display a distinct phenotype with dynamic changes in the first weeks of life. Hence, the continued abundance of Tregs may contribute to sustained inflammation preceding the development of BPD. Functional analyses are needed in order to elucidate whether Tregs have potential as future target for diagnostics and therapeutics.

Abstract
INTRODUCTION Pulmonary hypertension (PH) is a recognized complication of bronchopulmonary dysplasia (BPD). Recent guidelines recommend evaluating all infants with BPD for PH via echocardiogram, but the specific timing of this screening is controversial. We aimed to identify the timing of PH diagnosis in a cohort of very low birthweight infants (VLBW) to determine appropriate age at screening. METHODS We retrospectively reviewed data on 455 VLBW infants undergoing echocardiography at our institution. The timing of all echocardiograms, PH diagnosis on echocardiography, and BPD diagnosis at 36 weeks corrected age were extracted. PH was defined as dilation of the right sided chambers or RVH, flattening or leftward deviation of the septum, TR >25 mmHg, or 2/3 systemic pressures, or right to left shunting. RESULTS Fifteen VLBW infants had PH identified on echocardiography, of whom 11 had BPD and 2 died before BPD status at 36 weeks could be ascertained. PH was most often identified on echocardiography after 36 weeks corrected age, and typically around 40 weeks. Ten of the infants ultimately diagnosed with PH had previous echocardiograms performed that were negative for PH at 25-46 weeks. CONCLUSIONS In our cohort of VLBW infants, onset of PH was typically found later than the 36-38 week range used by recently described screening programs. These findings suggest a need to examine echocardiograms obtained after 36 weeks for evidence of late-onset PH in vulnerable infants born at VLBW.

Abstract
OBJECTIVE Chronic pain and borderline personality disorder (BPD) are commonly comorbid and jointly associated with increased symptoms of both disorders and clinical and functional impairment. Little is known, however, about specific links between these disorders. In a cross-sectional study of patients with chronic pain, we compared participants high or low on BPD symptoms on patterns of pain experience and types of child and adult traumas. METHODS Adults (N = 181) with chronic pain completed self-reports of pain severity, dimensions of pain experiencing, body coverage of pain, and clinical indicators of central sensitization (i.e., chronic hypersensitivity of the central nervous system), as well as measures of child and adult physical abuse, sexual abuse, trauma, and neglect. Participants also completed the McLean Screening Instrument for BPD. RESULTS Participants with clinically significant BPD symptoms (n = 32) reported more childhood sexual trauma, punishment, and neglect, as well as adult physical/sexual trauma, than those without elevated BPD symptoms. Among participants with clinically significant BPD symptoms, affective pain and central sensitization were elevated, potentially explained by heightened negative affect in BPD. CONCLUSION BPD symptoms are associated with increased clinical severity among patients with chronic pain as well as a unique manifestation of pain experiencing (i.e., increased affective pain and central sensitization in particular). Childhood trauma of all types is associated with chronic pain and BPD co-occurrence. Researchers and clinicians should assess for BPD in people with chronic pain to enhance conceptual models of the transaction between these disorders and to improve clinical care.
