Pragmatic trial evaluating a randomly allocated Supplemental Nutrition Assistance Program outreach and enrolment assistance programme in Michigan: study protocol.

Introduction: Low-income adults with disabilities experience disproportionately high rates of food insecurity and preventable healthcare utilisation. The Supplemental Nutrition Assistance Program (SNAP) can reduce food insecurity and improve health, but there are accessibility gaps in the SNAP enrolment process. Existing outreach and enrolment assistance programmes have been shown to boost SNAP enrolment, but their health effects are understudied.

Correlated excitonic signatures of individual van der Waals NiPS antiferromagnet nanoflakes.

Composite quasi-particles with emergent functionalities in spintronic and quantum information science can be realized in correlated materials due to entangled charge, spin, orbital, and lattice degrees of freedom. Here we show that by reducing the lateral dimension of correlated antiferromagnet NiPS flakes to tens of nanometers and thickness to less than ten nanometers, we can switch-off the bulk spin-orbit entangled exciton in the near-infrared (1.47 eV) and activate visible-range (1.

Enabling Oxidation Protection and Carrier-Type Switching for Bismuth Telluride Nanoribbons via Organic Molecule Coating.

Thermoelectric materials with high electrical conductivity and low thermal conductivity (e.g., BiTe) can efficiently convert waste heat into electricity; however, in spite of favorable theoretical predictions, individual BiTe nanostructures tend to perform less efficiently than bulk BiTe.

Coordinated regulation of the entry and exit steps of aromatic amino acid biosynthesis supports the dual lignin pathway in grasses.

Vascular plants direct large amounts of carbon to produce the aromatic amino acid phenylalanine to support the production of lignin and other phenylpropanoids. Uniquely, grasses, which include many major crops, can synthesize lignin and phenylpropanoids from both phenylalanine and tyrosine. However, how grasses regulate aromatic amino acid biosynthesis to feed this dual lignin pathway is unknown.

Evidence of a Uranium-Paddlewheel Node in a Catecholate-Based Metal-Organic Framework.

The interactions between uranium and non-innocent organic species are an essential component of fundamental uranium redox chemistry. However, they have seldom been explored in the context of multidimensional, porous materials. Uranium-based metal-organic frameworks (MOFs) offer a new angle to study these interactions, as these self-assembled species stabilize uranium species through immobilization by organic linkers within a crystalline framework, while potentially providing a method for adjusting metal oxidation state through coordination of non-innocent linkers.

Combating Fentanyl: National Guard Physician Assistants on the Front Lines of America's War Against Synthetic Opioids.

There is a significant threat to global health security due to synthetic opioids, illicitly manufactured fentanyl (IMF), and nefarious uses of pharmaceutical based agents (PBA). Since 2014, increased distribution of synthetic opioids including IMF into the US through China, India, and Mexico has resulted in devastating consequences to the average street drug user. Additionally, clandestine lab operations for pill manufacturing and distribution have increased, along with unintentional drug overdoses due to drugs being laced with fentanyl or some other synthetic opioid derivative.

Polymer networks of imine-crosslinked metal-organic cages: tuneable viscoelasticity and iodine adsorption.

The solution-state structure of an amine-functionalised CuL cage (MOP-15) is elucidated, enabling its direct covalent crosslinking into a series of highly tuneable organogels. These soft porous networks exhibit up to a ∼10-fold increase in capacity for iodine compared to the discrete cage precursor.

Induced Ferromagnetism in Epitaxial Uranium Dioxide Thin Films.

Actinide materials have various applications that range from nuclear energy to quantum computing. Most current efforts have focused on bulk actinide materials. Tuning functional properties by using strain engineering in epitaxial thin films is largely lacking.

Visualizing Grain Statistics in MOCVD WSe through Four-Dimensional Scanning Transmission Electron Microscopy.

Using four-dimensional scanning transmission electron microscopy, we demonstrate a method to visualize grains and grain boundaries in WSe grown by metal organic chemical vapor deposition (MOCVD) directly onto silicon dioxide. Despite the chemical purity and uniform thickness and texture of the MOCVD-grown WSe, we observe a high density of small grains that corresponds with the overall selenium deficiency we measure through ion beam analysis. Moreover, reconstruction of grain information permits the creation of orientation maps that demonstrate the nucleation mechanism for new layers-triangular domains with the same orientation as the layer underneath induces a tensile strain increasing the lattice parameter at these sites.

Use of predictive models to identify patients who are likely to benefit from refraction at a follow-up visit after cataract surgery.

Purpose: To develop predictive models to identify cataract surgery patients who are more likely to benefit from refraction at a four-week postoperative exam.

Methods: In this retrospective study, we used data of all 86,776 cataract surgeries performed in 2015 at a large tertiary-care eye hospital in India. The outcome variable was a binary indicator of whether the difference between corrected distance visual acuity and uncorrected visual acuity at the four-week postoperative exam was at least two lines on the Snellen chart.

Health expenditures by services and providers for 195 countries, 2000-2017.

Introduction: National Health Accounts are a significant source of health expenditure data, designed to be comprehensive and comparable across countries. However, there is currently no single repository of this data and even when compiled major gaps persist. This research aims to provide policymakers and researchers with a single repository of available national health expenditures by healthcare functions (ie, services) and providers of such services.

The Effectiveness of Discharge Planning for Psychiatric Inpatients With Varying Levels of Preadmission Engagement in Care.

Objective: This study examined the extent to which prehospital treatment engagement is related to posthospital follow-up treatment among psychiatric inpatients and whether the effects of inpatient discharge planning on posthospital follow-up treatment vary by level of pretreatment engagement in care.

Methods: New York State Medicaid and other administrative databases were used to examine service use by 18,793 adult patients discharged to the community after inpatient psychiatric care in 2012-2013. Outcomes included attending an outpatient mental health service within 7 days and within 30 days after discharge.

Assembly and Covalent Cross-Linking of an Amine-Functionalised Metal-Organic Cage.

The incorporation of reactive functional groups onto the exterior of metal-organic cages (MOCs) opens up new opportunities to link their well-defined scaffolds into functional porous solids. Amine moieties offer access to a rich catalogue of covalent chemistry; however, they also tend to coordinate undesirably and interfere with MOC formation, particular in the case of Cu paddlewheel-based MOCs. We demonstrate that tuning the basicity of an aniline-functionalized ligand enables the self-assembly of a soluble, amine-functionalized CuL lantern cage ().

py4DSTEM: A Software Package for Four-Dimensional Scanning Transmission Electron Microscopy Data Analysis.

Scanning transmission electron microscopy (STEM) allows for imaging, diffraction, and spectroscopy of materials on length scales ranging from microns to atoms. By using a high-speed, direct electron detector, it is now possible to record a full two-dimensional (2D) image of the diffracted electron beam at each probe position, typically a 2D grid of probe positions. These 4D-STEM datasets are rich in information, including signatures of the local structure, orientation, deformation, electromagnetic fields, and other sample-dependent properties.

Intrinsic helical twist and chirality in ultrathin tellurium nanowires.

Robust atomic-to-meso-scale chirality is now observed in the one-dimensional form of tellurium. This enables a large and counter-intuitive circular-polarization dependent second harmonic generation response above 0.2 which is not present in two-dimensional tellurium.

Factors Associated With Discharge Planning Practices for Patients Receiving Inpatient Psychiatric Care.

Objective: This study examined associations of patient, hospital, and service system factors with provision of discharge planning to individuals treated in hospital psychiatric units.

Methods: This retrospective cohort analysis used 2012-2013 New York State Medicaid claims data of 18,185 patients ages <65 years who were treated in hospital psychiatric units and discharged to the community. The claims data were linked to data from managed behavioral health care organizations indicating whether inpatient staff scheduled a follow-up outpatient appointment with a mental health provider.

Self-sorting of porous CuLL' metal-organic cages composed of isomerisable ligands.

We report the self-sorting of a dynamic combinatorial library (DCL) of metal-organic cages composed of a rotationally isomerisable ligand. Convergence of the DCL occurs upon crystallisation and leads to low-symmetry Cu4L2L'2 cages that display differing porosities based on their overall shape and ligand configuration.

Highly Specific Mouse Anti-Joining Chain of Human Immunoglobulin A.

Immunoglobulin A (IgA) antibodies are critical to mucosal protection, specifically dimeric IgA (dIgA) and secretory IgA (sIgA), which rely on the J chain to polymerize. There is an absence of monoclonal antibodies that can specifically bind to polymeric IgA without the need to denature the molecule. We generated a panel of highly specific mouse anti-J chain antibodies that react with both intact and denatured nonhuman primate dIgA and human dIgA and sIgA of both the IgA1 and IgA2 subclass.

IgA as a potential candidate for enteric monoclonal antibody therapeutics with improved gastrointestinal stability.

Mucosal surfaces of the gastrointestinal tract play an important role in immune homeostasis and defense and may be compromised by enteric disorders or infection. Therapeutic intervention using monoclonal antibody (mAb) offers the potential for treatment with minimal off-target effects as well as the possibility of limited systemic exposure when administered orally. Critically, to achieve efficacy at luminal surfaces, mAb must remain stable and functionally active in the gastrointestinal environment.

A covalent deprotection strategy for assembling supramolecular coordination polymers from metal-organic cages.

A CuL metal-organic cage (MOC) composed of amine-protected ligands forms supramolecular coordination polymers (SCPs) upon covalent post-assembly deprotection. The amorphous SCPs form by virtue of aniline-copper coordination and possess a tunable porosity based on the rate of deprotection.

Effect of Scheduling a Post-Discharge Outpatient Mental Health Appointment on the Likelihood of Successful Transition From Hospital to Community-Based Care.

Objective: This study examined a cohort of 15,520 inpatient psychiatric discharges to determine associations between scheduling an outpatient mental health appointment as part of discharge planning and attending outpatient care following discharge after control for patient, hospital, and system characteristics.

Methods: 2012-2013 New York State Medicaid and other administrative databases were used to examine patients who were aged under 65 years, admitted to an inpatient psychiatric unit, and discharged to the community. Outcomes included attending an outpatient mental health service within 7 and 30 days following inpatient discharge.
