The biology driving individual patient responses to severe acute respiratory syndrome coronavirus 2 infection remains ill understood. Here, we developed a patient-centric framework leveraging detailed longitudinal phenotyping data and covering a year after disease onset, from 215 infected individuals with differing disease severities. Our analyses revealed distinct 'systemic recovery' profiles, with specific progression and resolution of the inflammatory, immune cell, metabolic and clinical responses. In particular, we found a strong inter-patient and intra-patient temporal covariation of innate immune cell numbers, kynurenine metabolites and lipid metabolites, which highlighted candidate immunologic and metabolic pathways influencing the restoration of homeostasis, the risk of death and that of long COVID. Based on these data, we identified a composite signature predictive of systemic recovery, using a joint model on cellular and molecular parameters measured soon after disease onset. New predictions can be generated using the online tool http://shiny.mrc-bsu.cam.ac.uk/apps/covid-19-systemic-recovery-prediction-app , designed to test our findings prospectively.

Altering the intracellular trafficking of Necator americanus GST-1 antigen yields novel hookworm mRNA vaccine candidates.
PLoS Negl Trop Dis

Department of Pediatrics, National School of Tropical Medicine, Baylor College of Medicine, Houston, Texas, United States of America.
Background: The antigen Na-GST-1, expressed by the hookworm Necator americanus, plays crucial biochemical roles in parasite survival. This study explores the development of mRNA vaccine candidates based on Na-GST-1, building on the success of recombinant Na-GST-1 (rNa-GST-1) protein, currently assessed as a subunit vaccine candidate, which has shown promise in preclinical and clinical studies.
Methodology/findings: By leveraging the flexible design of RNA vaccines and protein intracellular trafficking signal sequences, we developed three variants of Na-GST-1 as native (cytosolic), secretory, and plasma membrane-anchored (PM) antigens.
Focused Investigation of Facial Nerve Dysfunction After Mandibular Distraction Osteogenesis for Robin Sequence.
J Craniofac Surg

Division of Plastic and Reconstructive Surgery, Children's National Hospital.
Facial nerve dysfunction (FND) is a well-recognized but poorly documented complication of mandibular distraction osteogenesis (MDO) for Robin sequence (RS). This study aims to document the authors' experiences with FND and identify risk factors associated with this adverse event. A retrospective review of a prospectively gathered database was performed to identify patients with RS who underwent MDO at the authors' institution from March 2016 to June 2023.

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) results from maternal antibodies targeting fetal platelets during pregnancy, often causing hemorrhagic manifestations detectable antenatally or shortly after birth. We report an atypical form of FNAIT with delayed onset in a healthy, breastfed male infant who developed diffuse petechiae 2 weeks after birth due to severe thrombocytopenia. The mother was shown to be negative for the human platelet antigen-1a (HPA-1a) allele but had anti-HPA-1a IgG antibodies, while the father and newborn were HPA-1a positive, confirming the diagnosis.

Significance: In an aging population, the number of people living with neurodegenerative disease is projected to increase. It is vital to develop reliable, noninvasive biomarkers to detect disease onset and monitor progression, and there is a growing body of research into the ocular surface as a potential source of such biomarkers.
Background: This article reviews the potential of in vivo corneal confocal microscopy and tear fluid analysis as tools for biomarker development.
Multi-miRNAs-Mediated Hepatic Lepr Axis Suppression: A Pparg-Dicer1 Pathway-Driven Mechanism in Spermatogenesis for the Intergenerational Transmission of Paternal Metabolic Syndrome.

Bisphenol A (BPA) is an "environmental obesogen" and this study aims to investigate the intergenerational impacts of BPA-induced metabolic syndrome (MetS), specifically focusing on unraveling mechanisms. Exposure to BPA induces metabolic disorders in the paternal mice, which are then transmitted to offspring, leading to late-onset MetS. Mechanistically, BPA upregulates Srebf1, which in turn promotes the Pparg-dependent transcription of Dicer1 in spermatocytes, increasing the levels of multiple sperm microRNAs (miRNAs).
