Machine learning has become a powerful tool for computational analysis in the biomedical sciences, with its effectiveness significantly enhanced by integrating domain-specific knowledge. This integration has give rise to informed machine learning, in contrast to studies that lack domain knowledge and treat all variables equally (uninformed machine learning). While the application of informed machine learning to bioinformatics and health informatics datasets has become more seamless, the likelihood of errors has also increased.

Introduction: Accurate prognostication in comatose survivors of cardiac arrest is a challenging and high-stakes endeavor. We sought to determine whether internal EEG subparameters extracted by the Bispectral Index (BIS) monitor, a device commonly used to estimate depth-of-anesthesia intraoperatively, could be repurposed to predict recovery of consciousness after cardiac arrest.
Methods: In this retrospective cohort study, we trained a 3-layer neural network to predict recovery of consciousness to the point of command following versus not based on 48 hours of continuous EEG recordings in 315 comatose patients admitted to a single US academic medical center after cardiac arrest (Derivation cohort: N=181; Validation cohort: N=134).

Background: Chronic kidney disease (CKD) is associated with higher risk of myocardial infarction and anemia. Among patients with anemia and CKD who experience myocardial infarction, it remains uncertain if a liberal red blood cell transfusion threshold strategy (hemoglobin cutoff [Hgb] < 10 g/dL) is superior to a restrictive transfusion threshold (Hgb 7-8 g/dL) strategy.
Methods: Among the 3,504 patients enrolled in the Myocardial Ischemia and Transfusion (MINT) trial with non-missing creatinine, we compared baseline characteristics and 30-day and 6-month outcomes of patients without CKD (N = 1279), CKD with eGFR 30-60 mL/min/1.

Motivation: Accurate prediction of protein side-chain conformations is necessary to understand protein folding, protein-protein interactions and facilitate de novo protein design.
Results: Here we apply torsional flow matching and equivariant graph attention to develop FlowPacker, a fast and performant model to predict protein side-chain conformations conditioned on the protein sequence and backbone. We show that FlowPacker outperforms previous state-of-the-art baselines across most metrics with improved runtime.

In this study, we explored the intricate relationship between Pannexin 1 (PANX1) and the Hippo signaling pathway effector, Yes-associated protein (YAP). Analysis of The Cancer Genome Atlas (TCGA) data revealed a significant positive correlation between PANX1 mRNA and core Hippo components, Yes-associated protein 1 [YAP], Transcriptional coactivator with PDZ-binding motif [TAZ], and Hippo scaffold, Ras GTPase-activating-like protein IQGAP1 [IQGAP1], in invasive cutaneous melanoma and breast carcinoma. Furthermore, we demonstrated that PANX1 expression is upregulated in invasive melanoma cell lines and is associated with increased YAP protein levels.

The diagnosis of bipolar disorder (BD) in young children has been a topic of debate, in part owing to varied interpretation of manic-like symptoms. We examined how expert academic clinicians participating in the pediatric bipolar biobank varied in their interpretation and application of Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria and diagnoses. Study co-investigators reviewed 12 standardized narratives and for each marked a visual analog scale with their confidence in the presence of manic episodes and criteria.

Objective: Youth with juvenile idiopathic arthritis (JIA) experience elevated rates of internalizing symptoms, although more research is required to understand this phenomenon. Perfectionism, a multidimensional personality trait that involves dimensions such as striving for flawlessness (self-oriented perfectionism) and feeling that others demand perfection (socially-prescribed perfectionism), is a well-known risk factor for internalizing symptoms that has received minimal attention in pediatric populations. Preregistered hypotheses explored the relationships between youth and parent perfectionism and symptoms of depression and anxiety in youth with JIA, as mediated by (a) youth/parent negative self-evaluations and (b) youth self-concealment.
