Severe Maternal Morbidity Associated With Chronic Hypertension, Preeclampsia, and Gestational Hypertension.

Importance: Chronic hypertension and preeclampsia are leading risk enhancers for maternal-neonatal morbidity and mortality. Severe maternal morbidity (SMM) indicators include heart, kidney, and liver disease, but studies have not excluded patients with preexisting diseases that define SMM. Thus, SMM risks for uncomplicated chronic hypertension specific to preeclampsia remain unclear.

Topical review: family psychosocial risk screening and social determinants of health assessment.

Objective: Social-ecological factors are highly congruent with social determinants of health (SDOH): Economic Stability; Educational Access/Quality; Healthcare Access/Quality; Neighborhood/Built Environment; and Social/Community Context. In this topical review, the correspondence of social-ecological theory with SDOH and assessment approaches is reviewed. The Psychosocial Assessment Tool (PAT) is used to show how existing tools may facilitate SDOH screening.

Characterizing Conical Intersections of Nucleobases on Quantum Computers.

Hybrid quantum-classical computing algorithms offer significant potential for accelerating the calculation of the electronic structure of strongly correlated molecules. In this work, we present the first quantum simulation of conical intersections (CIs) in a biomolecule, cytosine, using a superconducting quantum computer. We apply the contracted quantum eigensolver (CQE)─with comparisons to conventional variational quantum deflation (VQD)─to compute the near-degenerate ground and excited states associated with the conical intersection, a key feature governing the photostability of DNA and RNA.

Restoring ceftolozane susceptibility: a role for diazabicyclooctane β-lactamase inhibitors?

Paired baseline and post-exposure isolates from 34 patients who developed ceftolozane-tazobactam (TOL-TAZ) resistance following treatment of multidrug-resistant (MDR) infections were analyzed to determine if ceftolozane with an alternative β-lactamase inhibitor could restore susceptibility. The median baseline TOL-TAZ MIC was 2 mg/L; 88% of post-exposure isolates harbored new mutations. Median MIC fold-increase from baseline was 32-, 24-, 16-, and 6-fold for ceftolozane-tazobactam, ceftolozane-avibactam (AVI), ceftolozane-relebactam (REL), and ceftolozane-durlobactam (DUR), respectively.

Vitamin B2 Operates by Dual Thermodynamic and Kinetic Mechanisms to Selectively Tailor Urate Crystallization.

Here we demonstrate how a biologically relevant molecule, riboflavin (vitamin B2), operates by a dual mode of action to effectively control crystallization of ammonium urate (NHHU), which is associated with cetacean kidney stones. In situ microfluidics and atomic force microscopy experiments confirm a strong interaction between riboflavin and NHHU crystal surfaces that substantially inhibits layer nucleation and spreading by kinetic mechanisms of step pinning and kink blocking. Riboflavin does not alter the distribution of tautomeric urate isomers, but its adsorption on NHHU crystal surfaces does interfere with the effects of minor urate tautomer by limiting its ability to induce NHHU crystal defects while also suppressing NHHU nucleation and inhibiting crystal growth by 80% at an uncharacteristically low modifier concentration.

Photochemistry of Microsolvated Nitrous Acid: Observation of the Water-Separated Complex of Nitric Oxide and Hydroxyl Radical.

The photochemistry of nitrous acid (HONO) plays a crucial role in atmospheric chemistry as it serves as a key source of hydroxyl radicals (OH) in the atmosphere; however, our comprehension of the underlying mechanism for the photochemistry of HONO especially in the presence of water is far from being complete as the transient intermediates in the photoreactions have not been observed. Herein, we report the photochemistry of microsolvated HONO by water in a cryogenic N matrix. Specifically, the 1:1 hydrogen-bonded water complex of HONO was facially prepared in the matrix through stepwise photolytic O oxidation of the water complex of imidogen (NH-HO) via the intermediacy of the elusive water complex of peroxyl isomer HNOO.

Electrocatalysis: From Planar Surfaces to Nanostructured Interfaces.

The reactions critical for the energy transition center on the chemistry of hydrogen, oxygen, carbon, and the heterogeneous catalyst surfaces that make up electrochemical energy conversion systems. Together, the surface-adsorbate interactions constitute the electrochemical interphase and define reaction kinetics of many clean energy technologies. Practical devices introduce high levels of complexity where surface roughness, structure, composition, and morphology combine with electrolyte, pH, diffusion, and system level limitations to challenge our ability to deconvolute underlying phenomena.

An online case-based radiology course improves veterinary students' day one competency in small animal radiographic interpretation.

Background: Accurate radiographic interpretation is an important day one skill. A case-based radiology course (CBC) demonstrated better learning outcomes than a lecture-based course (LBC) immediately and after a one-semester period. The aim of this study was to compare long-term learning outcomes of both groups.

Tumour size is associated with growth rates of >0.5 cm/year and delayed intervention in small renal masses in patients on active surveillance.

Objective: To evaluate the association between tumour size and the growth rate (GR) of small renal masses (SRMs) in patients managed by active surveillance (AS).

Materials And Methods: We queried the prospective, multi-institutional Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) registry for patients on AS with an imaging interval of ≥6 months, identifying 456 patients. We tracked tumour size over time; a GR >0.

Interstellar spectroscopic detection of HC(S)NC and DC(S)NC.

The detection of HC(S)CN in TMC-1 suggests that HC(S)NC may also exist. To aid in its possible detection, HC(S)NC and its deuterated isotopologue DC(S)NC were investigated via high-level ab initio methods, specifically CCSD(T) and CCSD(T)-F12. By utilizing multidimensional potential energy surfaces derived from explicitly correlated coupled-cluster calculations, we analyzed their geometrical parameters, vibrational frequencies, rotational constants, and a comprehensive set of spectroscopic constants generated via the vibrational second-order perturbation theory, vibrational self-consistent field, and vibrational configuration interaction theory(VCI) approaches.

: active learning in neutron reflectometry for fast data acquisition.

Neutron reflectometry (NR) is a powerful technique for interrogating the structure of thin films at interfaces. Because NR measurements are slow and instrument availability is limited, measurement efficiency is paramount. One approach to improving measurement efficiency is active learning (AL), in which the next measurement configurations are selected on the basis of information gained from the partial data collected so far.

Contrastive learning with transformer for adverse endpoint prediction in patients on DAPT post-coronary stent implantation.

Background: Effective management of dual antiplatelet therapy (DAPT) following drug-eluting stent (DES) implantation is crucial for preventing adverse events. Traditional prognostic tools, such as rule-based methods or Cox regression, despite their widespread use and ease, tend to yield moderate predictive accuracy within predetermined timeframes. This study introduces a new contrastive learning-based approach to enhance prediction efficacy over multiple time intervals.

Flow-based In Vivo Method to Enumerate Translating Ribosomes and Translation Elongation Rate.

Protein synthesis is by far the most energetically costly cellular process in rapidly dividing cells. Quantifying translating ribosomes in individual cells and their average mRNA transit rate is arduous. Quantitating assembled ribosomes in individual cells requires electron microscopy and does not indicate ribosome translation status.

Chronic Severe Neutropenia Associated With Intravenous Immunoglobulin for Multifocal Motor Neuropathy.

Intravenous immunoglobulin (IVIG) is an immunomodulatory therapy derived from pooled donor immunoglobulins and used for treatment of various autoimmune conditions. Here we report the diagnosis and management of IVIG-induced chronic severe neutropenia with absolute neutrophil count <0.5×10/µL in a patient with multifocal motor neuropathy.

Medicare Resource Use Differs by English Reading Proficiency.

Background And Objectives: Medicare coverage decisions are complex. The Centers for Medicare & Medicaid Services (CMS) provides a hotline, handbook, and website to help Medicare beneficiaries understand their benefits and coverage options, yet it is unclear what factors affect beneficiary use of these resources. We examined limited English speaking and English reading proficiency status as predictors of CMS Medicare informational resource use in a nationally representative sample of Medicare beneficiaries.

External group-based implementation facilitation may be one promising approach. This study's objective is to detail the development and delivery of a pragmatic implementation facilitation approach to support the national rollout of caregiver training, Caregivers FIRST, at over 140 Veterans Health Administration (VHA) sites.

Population imaging of internal state circuits relevant to psychiatric disease: a review.

Internal states involve brain-wide changes that subserve coordinated behavioral and physiological responses for adaptation to changing environments and body states. Investigations of single neurons or small populations have yielded exciting discoveries for the field of neuroscience, but it has been increasingly clear that the encoding of internal states involves the simultaneous representation of multiple different variables in distributed neural ensembles. Thus, an understanding of the representation and regulation of internal states requires capturing large population activity and benefits from approaches that allow for parsing intermingled, genetically defined cell populations.

The Role of Immunohistochemistry for AMACR/p504s and p63 in Distinguishing Prostate Cancer from Benign Prostate Tissue Samples in Botswana.

Introduction: Prostate cancer (CaP) is the most common malignancy and the second leading cause of cancer-related deaths among men in Botswana. Currently, diagnosing CaP relies on examining prostate biopsy samples, which can be challenging due to benign mimics. This study aims to evaluate the potential of Alpha-methyl acyl-CoA racemase (AMACR/p504s) and p63, as diagnostic markers for CaP.

Drought as an emergent driver of ecological transformation in the twenty-first century.

Under climate change, ecosystems are experiencing novel drought regimes, often in combination with stressors that reduce resilience and amplify drought's impacts. Consequently, drought appears increasingly likely to push systems beyond important physiological and ecological thresholds, resulting in substantial changes in ecosystem characteristics persisting long after drought ends (i.e.

Storm Surge Projection and Objective-Based Risk Management for Climate Change Adaptation along the US Atlantic Coast.

Climate change brings intense hurricanes and storm surges to the US Atlantic coast. These disruptive meteorological events, combined with sea level rise (SLR), inundate coastal areas and adversely impact infrastructure and environmental assets. Thus, storm surge projection and associated risk quantification are needed in coastal adaptation planning and emergency management.
