Background: While more and more people tend to use herbal products thinking they are safer than conventional western medicine, the reality is other. If natural products are bio-active and possess potential therapeutic activities, then the benefit/risk balance should be considered like any other health product. Some herbs are known to have the potential to interact with patient's treatment and to cause adverse drug reactions.

Introduction: Pregnancy-associated mortality involving opioids represents a significant public health issue. Limited social support is a known factor, contributing to a more complex recovery and a greater risk for relapse and overdose. Community-based doulas have been used in other marginalized populations yet are under-studied among pregnant and parenting persons with Opioid Use Disorder (OUD).

Background: Geographic atrophy (GA) is a significant cause of vision loss in patients with age-related macular degeneration (AMD). Current treatments are limited to anti-complement drugs, which have limited efficacy to delay progression with significant risk of complications. Levodopa (L-DOPA) is a byproduct of melanin synthesis that is associated with reduced development of neovascular AMD.

Article Synopsis
  • The study investigates dome-shaped macula (DSM) in preterm and full-term infants using advanced optical imaging technology, highlighting increased occurrence in preterm infants.
  • Out of 217 imaging sessions, DSM was found in 40% of preterm infants compared to 14% of full-term infants, showing a significant difference in diagnosis timing and dome characteristics.
  • The results suggest that while DSM is common in infants and typically round in shape, it isn't linked to macular fluid presence, indicating unique differences from DSM in older children and adults.

The use of graph centrality measures applied to biological networks, such as protein interaction networks, underpins much research into identifying key players within biological processes. This approach however is restricted to dyadic interactions and it is well-known that in many instances interactions are polyadic. In this study we illustrate the merit of using hypergraph centrality applied to a hypernetwork as an alternative.

Objective: One concern about the use of risk assessment instruments in legal decisions is the potential for disparate impact by race or ethnicity. This means that one racial or ethnic group will experience harsher legal outcomes than another because of higher or biased risk estimates. We conducted a systematic review of the literature to synthesize research examining the real-world impact of juvenile and adult risk instruments on racial/ethnic disparities in legal decision making.

In the late 1990s, the San Miguel Island fox (Urocyon littoralis littoralis) faced near-extinction. Fourteen of the 15 remaining foxes were placed into an island-based captive breeding program used to repopulate the island. Although the fox population in San Miguel reached pre-decline numbers by 2010, a second decline started around 2014, coincidental with a newly observed acanthocephalan parasite.

Objective: Optic nerve hypoplasia (ONH), the congenital underdevelopment of the optic nerve, is an increasing cause of visual impairment and is associated with pituitary dysfunction. Past studies have focused on the relationship between ONH, pituitary deficiencies, and brain imaging. However, recent studies have demonstrated the true risk for hypopituitarism lies with the presence or absence of ONH, irrespective of midline brain findings.

Electrochemical conversion of carbon dioxide (CO) offers the opportunity to transform a greenhouse gas into valuable starting materials, chemicals, or fuels. Since many CO capture strategies employ aqueous alkaline solutions, there is interest in catalyst systems that can act directly on such capture solutions. Herein, we demonstrate new catalyst designs where the electroactive molecules readily mediate the CO-to-CO conversion in aqueous solutions between pH 4.

ConspectusTo say the least, releasing CO into the atmosphere is reaping undue environmental consequences given the ever-present increase in severe global weather events over the past five years. However, it can be argued that-at least in the confines of current technological capabilities-the atmospheric release of CO is somewhat unavoidable given that even shifting toward clean energy sources-such as solar, nuclear, wind, battery, or H power-incurs an initial carbon requirement by way of manufacturing the very production abilities through which "clean" energy is generated. Even years from now, experts agree that energy production will be diversified and-as the global population continues to drive the growth of global energy consumption-thermal power derived from carbon combustion is likely to remain one intrinsic energetic source, of which CO will always be a byproduct.

Objective: To describe two main pillars of the Maryland Maternal Health Innovation Program (MDMOM): (1) centering equity and (2) fostering broad stakeholder collaboration and trust.

Methods: We summarized MDMOM's key activities and used severe maternal morbidity (SMM) surveillance and program monitoring data to quantify MDMOM's work on the two pillars. We developed measures of hospital engagement with MDMOM (participation in quality improvement [QI] activities, participation in check-in meetings, staff involvement) and with other partners (participation in QI activities, representation in state-level groups).

The hemagglutinin-esterase-fusion (HEF) protein binds 9-O-acetylated sialic acids-containing glycans on the cell surface and drives influenza D virus (IDV) entry. The HEF is a primary determinant of the exceptional thermal and acid stability observed in IDV infection biology. Here, we expressed and purified the receptor binding domain (RBD) of the IDV HEF protein in Escherichia coli and characterized its receptor binding and antigenic properties.

  • In ten states, physical therapists are allowed to order diagnostic imaging, which helps them see if patients need more tests or treatments.
  • A study in North Dakota found that many physical therapists believe ordering these tests would help their patients but still don’t do it.
  • The study also revealed that barriers like complicated procedures, limited permissions, and lack of training make it hard for therapists to refer patients for imaging.

Purpose: Existing resources that characterize the essentiality status of genes are based on either proliferation assessment in human cell lines, viability evaluation in mouse knockouts, or constraint metrics derived from human population sequencing studies. Several repositories document phenotypic annotations for rare disorders; however, there is a lack of comprehensive reporting on lethal phenotypes.

Methods: We queried Online Mendelian Inheritance in Man for terms related to lethality and classified all Mendelian genes according to the earliest age of death recorded for the associated disorders, from prenatal death to no reports of premature death.

Oxide-dispersion-strengthened (ODS) steels have long been viewed as a prime solution for harsh environments. However, conventional manufacturing of ODS steels limits the final product geometry, is difficult to scale up to large components, and is expensive due to multiple highly involved, solid-state processing steps required. Additive manufacturing (AM) can directly incorporate dispersion elements (e.
