    Abstract This study provides new evidence on how prenatal WIC participation influences pregnancy-related outcomes, using a large dataset of Medicaid mothers with two or more singleton births. Our analysis suggests there is negative selection by maternal unobserved factors even with a relatively homogenous sample and a rich set of observed characteristics. The conservative estimates from multiple regression which doesn't address maternal unobserved heterogeneity already demonstrate beneficial effects on a range of outcomes. The concern of mis-specification or extrapolation in the linear model is also ruled out. Controlling for the mother fixed effects, we find more statistically significant estimates which are usually larger in size. The within-mother estimates are robust in a series of sensitivity checks especially multiple inference adjustments. Overall, we find WIC does work to improve infant health and maternal health behaviors as well as reduce usage of costly maternity care.

    Abstract Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been a pandemic and affected public health greatly. While COVID-19 primarily damages the lungs, leading to cough, sore throat, pneumonia, or acute respiratory distress syndrome, it also infects other organs and tissues, including the cardiovascular system. In particular, myocarditis is a well-recognized severe complication of COVID-19 infection and could result in adverse outcomes. Angiotensin-Converting Enzyme2 is thought to play a pivotal role in SARS-CoV-2 infection, and immune overresponse causes overwhelming damage to the host's myocardium. Direct viral infection and injury do take a part as well, but more evidence is needed to strengthen this proposal. The clinical abnormalities include elevated cardiac biomarkers and electrocardiogram changes and impaired cardiac function that might be presented in echocardiography and cardiovascular magnetic resonance imaging. If necessary, the endomyocardial biopsy would give more forceful information to diagnosis and aid in treatment. Comparisons between COVID-19 myocarditis and other viral myocarditis are also discussed briefly.

    Abstract Thermosets and their composites have occupied a key place in the polymeric material industry for both plastics and rubbers. Carbon material/thermoset composite is a major category thereof. The addition of carbon material (such as carbon fibers, carbon nanotubes (CNTs), and graphene) endows polymeric materials with better mechanical properties, enhanced optical and electrical properties, etc. However, due to the thermoset nature, the covalently crosslinked network brings huge reprocessing and recycling difficulties. The development of vitrimers paves a new way to produce recyclable and degradable thermosets. A series of carbon material/vitrimer composites have also been innovated, aiming at sustainable high-performance materials with better physical properties, recyclability, reprocessablity, and other novel stimuli-responsive functions. This review summarized the progress of carbon material/vitrimer composites in the past decade. A general introduction of vitrimer and the preparation strategies of different kinds of carbon material/vitrimer composites are given at first. Because of the vitrimeric nature, the service life of those composites could be significantly prolonged by reprocessing, healing, and recycling, the related strategies of which are described and summarized in detail. Then, the improved properties and new functions enabled by the incorporation of fillers are also overviewed. Our outlook on the future directions of carbon material/vitrimer composites is present at the end.

    Abstract Abstract Background Student engagement can predict successful learning outcomes and academic development. The expansion of simulation-based medical and healthcare education creates challenges for educators, as they must help students engage in a simulation-based learning environment. This research provides a reference for facilitators of simulation teaching and student learning in medical and health-related majors by providing a deep understanding of student engagement in a simulation-based learning environment. Methods We conducted semi-structured interviews with ten medical and healthcare students to explore their learning types and characteristics in a simulation-based learning environment. Thematic analysis was used to analyse the data. Results The interviews were thematically analysed to identify three types of student engagement in the simulation-based learning environment: reflective engagement, performance engagement, and interactive engagement. The analysis also identified eight sub-themes: active, persistent, and focused thinking engagement; self-directed-learning thinking engagement with the purpose of problem solving; active “voice” in class; strong emotional experience and disclosure; demonstration of professional leadership; interaction with realistic learning situations; support from teammates; and collegial facilitator-student interaction. Conclusions The student interview and thematic analysis methods can be used to study the richness of student engagement in simulation-based learning environments. This study finds that student engagement in a simulation-based learning environment is different from that in a traditional environment, as it places greater emphasis on performance engagement, which combines both thinking and physical engagement, as well as on interactive engagement as generated through interpersonal interactions. Therefore, we suggest expanding the learning space centring around “inquiry”, as it can help strengthen reflective communication and dialogue. It also facilitates ...

    Abstract While many economic studies have explored the role of prenatal care in infant health production, the literature is sporadic on the effects of prenatal care on the mother. This research contributes to this understudied but important area using a unique large dataset of sibling newborns delivered by 0.17 million mothers. We apply within-mother estimators to find robust evidence that poor prenatal care utilization due to late onset of care, low frequency of care visits, or combinations of the two significantly increases the risks of maternal insufficient gestational weight gain, prenatal smoking, premature rupture of membranes, precipitous labor, no breastfeeding, postnatal underweight, and postpartum smoking. The magnitude of the estimates relative to the respective sample means of the outcome variables ranges from 3% to 33%. The results highlight the importance of receiving timely and sufficient prenatal care in improving maternal health and health behaviors during pregnancy as well as after childbirth.

    Abstract In this study, the effects of different soluble proteins, including collagen peptides (CP), soy protein hydrolysate (HSPI), whey protein isolate (WPI), sodium caseinate (SC), and egg white protein (EWP), on the structural and mechanical properties of blends containing soy protein isolate (SPI) and wheat gluten (WG) were investigated using high-moisture extrusion. The addition of CP and HSPI resulted in a more pronounced fibrous structure with increased voids, attributing to their plasticizing effect that enhanced polymer chain mobility and reduced viscosity. WPI, SC, and EWP acted as crosslinking agents, causing early crosslink formation and decreased polymer chain mobility. These structural variations directly influenced the tensile properties of the extrudates, with CP displaying the highest anisotropic index. Moreover, the presence of soluble proteins impacts the permeability of the extrudates. These insights shed light on how soluble proteins can be used to modify the properties of SPI-WG blends, making them suitable for meat analogue production.

    Abstract The research was aimed to analyze the impact of epidemic pneumonia on nursing personnel’s mental health under wireless network background and to improve the selection of random forest classification (RFC) algorithm parameters by the whale optimization algorithm (WOA). Besides, a total of 148 in-service nursing personnel were selected as the research objects, and 148 questionnaires were recycled effectively. The collected data were analyzed by the improved RFC algorithm. In addition, the research investigated the impacts of demographic factors on nursing personnel’s mental health by the one-way variance method. The results demonstrated that the accuracy of the improved algorithm in training samples and test samples reached 83.3% and 81.6%, respectively, both of which were obviously higher than those of support vector machine (SVM) (80.1% and 79.3%, respectively) and back-propagation neural network (BPNN) (78.23% and 77.9%, respectively), and the differences showed statistical meanings P<0.05. The Patient Health Questionnaire-9 (PHQ-9) showed that the depression levels of 9.46% of the included personnel were above moderate. The Generalized Anxiety Disorder (GAD-7) demonstrated that the anxiety levels of 3.38% of the included personnel were above moderate. The insomnia severity index (ISI) indicated that the insomnia levels of 3.38% of the included personnel were above moderate. The average score of male personnel (3.65) was obviously lower than that of female personnel (3.71). Besides, the average scale score of married personnel (3.78) was significantly higher than that of unmarried personnel (3.65). The average scale scores of personnel with bachelor’s (3.66) and master’s degrees (3.62) were obviously lower than those of personnel with junior college (3.77) and technical secondary school (3.75) diplomas. The average scale score of personnel with over 5-year work experience (3.68) was significantly lower than that of personnel working for less than five years (3.72). The average scale score of personnel with ...
