Research has shown that children's internalizing symptom development during early childhood are shaped by biopsychosocial processes including physiology and parental symptoms. However, associations between maternal internalizing symptoms, child physiology and trajectories of child internalizing symptoms are not well understood. We used growth curve models to examine how maternal internalizing symptoms, child physiology and the interaction between maternal internalizing symptoms and child physiology may be associated with trajectories of internalizing symptoms during early childhood. Mothers reported their children's internalizing symptoms when children were 3, 4, 5 and 6 years of age, and mothers self-reported their own internalizing symptoms when children were 3. Respiratory Sinus Arrhythmia (RSA) was collected when children were 3.5-years-old. Results showed that there is a non-linear, quadratic trajectory across all participants from age 3 to 6. Maternal internalizing symptoms were not associated with children's internalizing symptoms at age 6, but were associated with both linear and quadratic change. Lower resting RSA was associated with greater increases in children's internalizing symptoms over time. Interactions between maternal internalizing symptoms and RSA were not associated with children's internalizing symptom development. The findings demonstrate that maternal internalizing symptoms and child physiology are independently associated with internalizing symptom development during early childhood.
Platelets are the most commonly discarded blood product in Canada, with the most common cause of in-date product loss being improper storage. Transport containers to maintain temperature and extend acceptable return time may represent a method to reduce wastage. The objective of this study was to evaluate the impact of a validated Platelet Transport Bag (PTB) on platelet wastage.

Thirty-six hospitals with the highest platelet discards were invited to participate in a before-after observational study. Hospitals were instructed to utilize a validated 4-h PTB for clinical situations where immediate transfusion was not planned. Five hospitals audited in-date platelet discards from July 2018 to November 2019 to characterize wastage causes. In-date platelet discard data 12 months before and after the start date for each site were analyzed to determine changes in wastage.

Of 36 hospital sites, 16 agreed to participate. Pre- and postdiscards were 277 and 301, respectively, for all sites combined. There were no significant before-after change in wastage rate (+0.05%, p = .51). Fifty discards were included in the detailed audit; the most common reasons were return to the blood bank after more than 60 min outside a PTB (n = 17, 34%) and return in a red cell cooler (n = 10, 20%).

Implementation of PTB did not improve wastage. Common causes of in-date discards were return after 1 h outside of a PTB and placement in a red cell cooler in error. Further research is required to investigate potential strategies to mitigate in-date platelet wastage.

Experimental animal models have been widely used to study development but cellular and molecular programmes may not be conserved across species. The advent of multiomic single-cell technologies and an increase in human developmental tissue biobank resources have facilitated single-cell multiomic studies focused on human immune development. A critical question in the near future is "How do we best reconcile scientific findings across multiple omic modalities, developmental time, and organismic space?" In this review, we discuss the application of single-cell multiomic technologies to unravel the major cellular lineages in the prenatal human immune system. We also identify key areas where the combined power of multiomics technologies can be leveraged to address specific immunological gaps in our current knowledge and explore new research horizons in human development.Geostatistical modeling for continuous point-referenced data has extensively been applied to neuroimaging because it produces efficient and valid statistical inference. However, diffusion tensor imaging (DTI), a neuroimaging technique characterizing the brain's anatomical structure, produces a positive-definite (p.d.) matrix for each voxel. Currently, only a few geostatistical models for p.d. matrices have been proposed because introducing spatial dependence among p.d. matrices properly is challenging. In this paper, we use the spatial Wishart process, a spatial stochastic process (random field), where each p.d. matrix-variate random variable marginally follows a Wishart distribution, and spatial dependence between random matrices is induced by latent Gaussian processes. This process is valid on an uncountable collection of spatial locations and is almost-surely continuous, leading to a reasonable way of modeling spatial dependence. Fenebrutinib inhibitor Motivated by a DTI data set of cocaine users, we propose a spatial matrix-variate regression model based on the spatial Wishart process. A problematic issue is that the spatial Wishart process has no closed-form density function. Hence, we propose an approximation method to obtain a feasible Cholesky decomposition model, which we show to be asymptotically equivalent to the spatial Wishart process model. A local likelihood approximation method is also applied to achieve fast computation. The simulation studies and real data application demonstrate that the Cholesky decomposition process model produces reliable inference and improved performance, compared to other methods.
The echocardiographic measurement of left ventricular (LV) ejection fraction (EF) is dependent on professional experience and adequate visualization. Tissue motion of mitral annular displacement (TMAD) can be easily assessed using speckle-tracking echocardiography (STE), even in patients with poor acoustic windows. Therefore, this study aimed to assess whether left ventricular ejection fraction (LVEF) can be estimated using STE-derived TMAD when LVEF is not available.

Four-hundred fifty-six outpatients were enrolled after excluding the patients whose LVEF measurements remained challenging or TMAD value could be confounded. An optimized regression model for LVEF-TMAD was developed in the derivation set (n=287), and its reliability was verified in the validation set (n=123) and regional wall motion abnormalities (RWMA) set (n=46).

In the derivation set, the power models had the highest F-value. Therefore, the power equations were chosen to estimate LVEF by TMAD in the validation set. There was a near-zero bias and a narrow range between the observed and estimated LVEF.
