To quantify and compare levels of potential biomarkers in neonates with (i) Bronchopulmonary dysplasia (BPD); (ii) BPD-associated pulmonary hypertension (BPD-PH); (iii) PH without BPD; and (iv) neonates without lung disease at ~36 weeks postmenstrual age.

Multiple potential biomarkers were measured in plasma samples of 90 patients using a multi-spot enzyme-linked immunosorbent assay. Statistical tests done included one-way ANOVA to compare levels of biomarkers between different groups.

Higher levels of ICAM-1 were present in infants with BPD and correlated with its severity. Infants with BPD have significantly higher levels of ANG-2 and lower levels of ANG-1. Infants with PH have higher levels of IL-6, IL-8, IL-10, and TNF-α. Infants with BPD-PH have significantly lower levels of MCP-1 and higher levels of IL-1β than infants with PH without BPD.

ICAM-1 may be used as a specific biomarker for diagnosis of BPD and its severity.

To examine the cost-effectiveness of prophylactic probiotics on necrotizing enterocolitis (NEC) prevention in very low birth weight (VLBW) infants.

We built a decision-analytic model using TreeAge. Effectiveness was assessed using quality-adjusted life-years (QALY). Primary outcome was an incremental cost-effectiveness ratio (ICER) expressed as cost per QALY gained. Costs were expressed in 2017 US dollars. Deterministic and probabilistic sensitivity analyses (SA) were performed.

For the base case analysis, the ICER of probiotics versus no probiotics for the prevention of NEC in VLBW infants was $1868/QALY. SA revealed that probiotics became cost-saving at a NEC rate of 6.5% and higher or with incremental NEC cost of $37,500 or higher.

Our model demonstrated that prophylactic probiotics were a cost-effective strategy in NEC reduction. SA confirmed that the model is customizable to various clinical settings and thus, can aid in understanding the economic impact of this intervention.

Previous studies have demonstrated that the activation and catalytic function of caspase-2 are key steps in MC to trigger apoptosis and/or cell cycle arrest of mitotically defective cells. However, the molecular mechanisms that regulate caspase-2 activation and its function are unclear. Here, we identify six new phosphorylation sites in caspase-2 and show that a key mitotic kinase, Aurora B kinase (AURKB), phosphorylates caspase-2 at the highly conserved residue S384. this website We demonstrate that phosphorylation at S384 blocks caspase-2 catalytic activity and apoptosis function in response to mitotic insults, without affecting caspase-2 dimerisation. Moreover, molecular modelling suggests that phosphorylation at S384 may affect substrate binding by caspase-2. We propose that caspase-2 S384 phosphorylation by AURKB is a key mechanism that controls caspase-2 activation during mitosis.An amendment to this paper has been published and can be accessed via a link at the top of the paper.An amendment to this paper has been published and can be accessed via a link at the top of the paper.An amendment to this paper has been published and can be accessed via a link at the top of the paper.Rheumatoid arthritis (RA) is a chronic inflammatory disease with fluctuating course of progression. Despite substantial improvement in treatments in recent years, treatment response is still not guaranteed. The aim of this study was to identify variation in Disease Activity Score 28 (DAS28) of RA patients in response to Tocilizumab, and to investigate both molecular and clinical factors influencing response. Clinical and biochemical data for 485 RA patients receiving Tocilizumab in combination with methotrexate were extracted from the LITHE phase III clinical study (NCT00106535), and post-hoc analysis conducted. Latent class mixed models were used to identify statistically distinct trajectories of DAS28 after the initiation of treatment. Biomarker measurements were then analysed cross-sectionally and temporally, to characterise patients by serological biomarkers and clinical factors. We identified three distinct trajectories of drug response class 1 (n = 85, 17.5%), class 2 (n = 338, 69.7%) and class 3 (n = 62, 12.8%). All groups started with high DAS28 on average (DAS28 > 5.1). Class 1 showed the least reduction in DAS28, with significantly more patients seeking escape therapy (p  less then  0.001). Class 3 showed significantly higher rates of improvement in DAS28, with 58.1% achieving ACR response levels compared to 2.4% in class 1 (p  less then  0.0001). Biomarkers of inflammation, MMP-3, CRP, C1M, showed greater reduction in class 3 compared to the other classes. Identification of more homogenous patient sub-populations of drug response may allow for more targeted therapeutic treatment regimens and a better understanding of disease aetiology.The concept of repression has been relegated to the periphery in current psychoanalytic theorizing. This is in part due to a reflexive and ill-informed avoidance of Freudian metapsychology, and in part due to preoccupation with 'primitive' and 'deeper' states of mind, a perspective that presumes that repression operates exclusively in 'higher level' or 'neurotic' forms of psychopathology. A careful scrutiny of psychoanalytic theory and clinical practice does not uphold such compartmentalization. Repression is ubiquitous in mental life. It contributes to normality (e.g., onset of latency), undergirds the 'psychopathology of everyday life' (e.g., parapraxes), exists alongside splitting in severe character disorders (e.g., borderline patients "forgetting" their appointments) and, by permitting a modified return of exiled mental contents, gives birth to neurotic symptoms as well as creative imagination. Taking Freud's seminal discourse on repression (in Repression. Standard Edition, vol 14. Hogarth, London, pp 141-158 1915a) as its starting point, this paper elucidates the complex, nuanced, and pervasive nature of this defense.
