    Abstract There has been heightened interest in identifying critical windows of exposure for adverse health outcomes; that is, time points during which exposures have the greatest impact on a person's health. Multiple informant models implemented using generalized estimating equations (MIM GEEs) have been applied to address this research question because they enable statistical comparisons of differences in associations across exposure windows. As interest rises in using MIMs, the feasibility and appropriateness of their application under settings of correlated exposures and partially missing exposure measurements requires further examination. We evaluated the impact of correlation between exposure measurements and missing exposure data on the power and differences in association estimated by the MIM GEE and an inverse probability weighted extension to account for informatively missing exposures. We assessed these operating characteristics under a variety of correlation structures, sample sizes, and missing data mechanisms considering various exposure-outcome scenarios. We showed that applying MIM GEEs maintains higher power when there is a single critical window of exposure and exposure measures are not highly correlated, but may result in low power and bias under other settings. We applied these methods to a study of pregnant women living with HIV to explore differences in association between trimester-specific viral load and infant neurodevelopment.

    Abstract Methods that allow the study of the structure of proteins in complex with nanomaterials promise to enhance our understanding of how biological molecules interface with inorganic materials. We used single-particle cryo-electron microscopy (cryo-EM) to demonstrate the potential for cryo-EM analysis to reveal structural details of protein-nanoparticle complexes. Two protein-nanomaterial complexes, namely, GroEL bound to platinum nanoparticles (GroEL-PtNP) and ferritin bound to an iron oxide nanoparticle, were used as model samples. For the GroEL-PtNP complex, a final reconstruction was obtained to 3.93 Å, which allowed us to fit the atomic model of GroEL into the resulting map. This sets the stage for future work and improvements on the use of cryo-EM for the study of protein-nanomaterial complexes.

    Abstract Objectives: To assess associations between diseases of despair (DoD) and incident atherosclerotic cardiovascular disease (ASCVD) among insured adults in the USA.
    Design: Retrospective cohort study.
    Setting: Highmark insurance claims data in the USA from 2017 to 2021.
    Participants: Adults with at least 10 months of continuous insurance enrolment, no record of ASCVD in the 2016 baseline year and no missing data on study variables.
    Primary and secondary outcome measures: Cox proportional hazard regression was used to calculate crude and adjusted hazard ratios (HR) and 95% confidence intervals (CI) to assess risk of ASCVD (composite of ischaemic cardiomyopathy, non-fatal ischaemic stroke, peripheral arterial disease or non-fatal acute myocardial infarction) by baseline DoD overall, and by the component conditions comprising DoD (alcohol-related disorders, substance-related disorders, suicidality) individually and in combination.
    Results: The DoD-exposed group had an age-adjusted rate of 20.5 ASCVD events per 1000 person-years, compared with 11.7 among the unexposed. In adjusted models, overall DoD was associated with increased risk of incident ASCVD (HR 1.42, 95% CI 1.36 to 1.47). Individually and in combination, component conditions of DoD were associated with higher risk for ASCVD relative to no DoD. Substance-related disorders were associated with 50% higher risk of incident ASCVD (HR 1.5, 95% CI 1.41 to 1.59), alcohol-related disorders and suicidality/intentional self-harm were associated with 33% and 30% higher risk, respectively (HR 1.33, 95% CI 1.26 to 1.41; HR 1.30, 95% CI 1.11 to 1.52). Co-occurring DoD components conferred higher risk still. The highest risk combination was substance-related disorders+suicidality (HR 2.01, 95% CI 1.44 to 2.82).
    Conclusions: Among this cohort of insured adults, documented DoD was associated with increased ASCVD risk. Further research to understand and address cardiovascular disease prevention in those with DoD could reduce costs, morbidity and mortality. Further examination of overlapping structural factors that may be contributing to concurrent rises in ASCVD and DoD in the USA is needed.

    Abstract Human cerebral organoids (COs) are three-dimensional self-organizing cultures of cerebral brain tissue differentiated from induced pluripotent stem cells. We have recently shown that COs are susceptible to infection with different subtypes of Creutzfeldt-Jakob disease (CJD) prions, which in humans cause different manifestations of the disease. The ability to study live human brain tissue infected with different CJD subtypes opens a wide array of possibilities from differentiating mechanisms of cell death and identifying neuronal selective vulnerabilities to testing therapeutics. However, the question remained as to whether the prions generated in the CO model truly represent those in the infecting inoculum. Mouse models expressing human prion protein are commonly used to characterize human prion disease as they reproduce many of the molecular and clinical phenotypes associated with CJD subtypes. We therefore inoculated these mice with COs that had been infected with two CJD subtypes (MV1 and MV2) to see if the original subtype characteristics (referred to as strains once transmitted into a model organism) of the infecting prions were maintained in the COs when compared with the original human brain inocula. We found that disease characteristics caused by the molecular subtype of the disease associated prion protein were similar in mice inoculated with either CO derived material or human brain material, demonstrating that the disease associated prions generated in COs shared strain characteristics with those in humans. As the first and only in vitro model of human neurodegenerative disease that can faithfully reproduce different subtypes of prion disease, these findings support the use of the CO model for investigating human prion diseases and their subtypes.

    Abstract Background: Sporadic Creutzfeldt-Jakob disease (sCJD), the most common human prion disease, is a fatal neurodegenerative disease with currently no treatment options. Stem cell therapy for neurodegenerative diseases is emerging as a possible treatment option. However, while there are a few clinical trials for other neurodegenerative disorders such as Parkinson's disease, prion disease cell therapy research has so far been confined to animal models.
    Methods: Here, we use a novel approach to study cell therapies in sCJD using a human cerebral organoid model. Cerebral organoids can be infected with sCJD prions allowing us to assess how neural precursor cell (NPC) therapy impacts the progression of sCJD. After 90 days of sCJD or mock infection, organoids were either seeded with NPCs or left unseeded and monitored for cellular composition changes, prion infection parameters and neuroelectrophysiological function at 180 days post-infection.
    Results: Our results showed NPCs integrated into organoids leading to an increase in neuronal markers and changes in cell signaling irrespective of sCJD infection. Although a small, but significant, decrease in protease-resistant PrP deposition was observed in the CJD-infected organoids that received the NPCs, other disease-associated parameters showed minimal changes. However, the NPCs had a beneficial impact on organoid function following infection. sCJD infection caused reduction in neuronal spike rate and mean burst spike rate, indicative of reduced action potentials. NPC seeding restored these electrophysiological parameters to the uninfected control level.
    Conclusions: Together with the previous animal studies, our results support that cell therapy may have some functional benefit for the treatment of human prion diseases.

    Abstract Objective: Intranasal medications have been proposed as adjuncts to out-of-hospital cardiac arrest (OHCA) care. We sought to quantify the effects of intranasal medication administration (INMA) in OHCA workflows.
    Methods: We conducted separate randomized OHCA simulation trials with lay rescuers (LRs) and first responders (FRs). Participants were randomized to groups performing hands-only cardiopulmonary resuscitation (CPR)/automated external defibrillator with or without INMA during the second analysis phase. Time to compression following the second shock (CPR2) was the primary outcome and compression quality (chest compression rate (CCR) and fraction (CCF)) was the secondary outcome. We fit linear regression models adjusted for CPR training in the LR group and service years in the FR group.
    Results: Among LRs, INMA was associated with a significant increase in CPR2 (mean diff. 44.1 s, 95% CI: 14.9, 73.3), which persisted after adjustment (
    Conclusions: INMA in LR resuscitation was associated with diminished resuscitation performance. INMA by FR did not impede key times or quality.
