The poly(A) signal, together with auxiliary elements, directs cleavage of a pre-mRNA and thus determines the 3' end of the mature transcript. In many species, including humans, the poly(A) signal is an AAUAAA hexamer, but we recently found that the deeply branching eukaryote Giardia lamblia uses a distinct hexamer (AGURAA) and lacks any known auxiliary elements. Our discovery prompted us to explore the evolutionary dynamics of poly(A) signals and auxiliary elements in the eukaryotic kingdom. We use direct RNA sequencing to determine poly(A) signals for four protists within the Metamonada clade (which also contains G. lamblia) and two outgroup protists. These experiments reveal that the AAUAAA hexamer serves as the poly(A) signal in at least four different eukaryotic clades, indicating that it is likely the ancestral signal, whereas the unusual Giardia version is derived. We find that the use and relative strengths of auxiliary elements are also plastic; in fact, within Metamonada, species like G. lamblia make use of a previously unrecognized auxiliary element where nucleotides flanking the poly(A) signal itself specify genuine cleavage sites. Thus, despite the fundamental nature of pre-mRNA cleavage for the expression of all protein-coding genes, the motifs controlling this process are dynamic on evolutionary timescales, providing motivation for future biochemical and structural studies as well as new therapeutic angles to target eukaryotic pathogens.

Two decades into the era of Electronic Health Records (EHRs), the promise of streamlining clinical care, reducing burden, and improving patient outcomes has yet to be realized. A cross-sectional family physician census conducted by the American Board of Family Medicine in 2022 and 2023 included self-reported physician EHR satisfaction. Of the nearly 10,000 responding family physicians, only one-in-four (26.2%) report being very satisfied and one-in-three (33.8%) were not satisfied. These low levels of satisfaction point to the need for greater transparency in the marketplace and pressure to increase user-centric EHR design.

Background:

Nested within a growing body of evidence of a gender pay gap in medicine are more alarming recent findings from family medicine: a gender pay gap of 16% can be detected at a very early career stage. This article explores qualitative evidence of women’s experiences negotiating for their first job out of residency to ascertain women’s engagement with and approach to the negotiation process.

Methods:

We recruited family physicians who graduated residency in 2019 and responded to the American Board of Family Medicine 2022 graduate survey. We developed a semistructured interview guide following a modified life history approach to uncover women’s experiences through the transitory stages from residency to workforce. A qualitative researcher used Zoom to interview 19 geographically and racially diverse early career women physicians. Interviews were transcribed verbatim and analyzed using NVivo software following an Inductive Content Analysis approach.

Results:

Three main themes emerged from the data. First, salary was found to be nonnegotiable, exemplified by participants’ inability to change initial salary offers. Second, the role of peer support throughout residency and early career was crucial to uncovering and rectifying salary inequity. Third, a pay expectation gap was identified among women from minority and low-income households.

Conclusion:

To rectify the gender pay gap in medicine, a systems-level approach is required. This can be achieved through various levels of interventions: societally expanding the use of and removing the stigma around parental leave, recognizing the importance of contributions not currently valued by productivity-based payment models, examining assumptions about leadership; and institutionally moving away from fee-for-service systems, encouraging flexible schedules, increasing salary transparency, and improving advancement transparency.

The SARS-CoV-2 frameshifting element (FSE) has been intensely studied and explored as a therapeutic target for coronavirus diseases, including COVID-19. Besides the intriguing virology, this small RNA is known to adopt many length-dependent conformations, as verified by multiple experimental and computational approaches. However, the role these alternative conformations play in the frameshifting mechanism and how to quantify this structural abundance has been an ongoing challenge. Here, we show by DMS and dual-luciferase functional assays that previously predicted FSE mutants (using the RAG graph theory approach) suppress structural transitions and abolish frameshifting. Furthermore, correlated mutation analysis of DMS data by three programs (DREEM, DRACO, and DANCE-MaP) reveals important differences in their estimation of specific RNA conformations, suggesting caution in the interpretation of such complex conformational landscapes. Overall, the abolished frameshifting in three different mutants confirms that all alternative conformations play a role in the pathways of ribosomal transition.

The CYP3A7 enzyme accounts for ~50% of the total cytochrome P450 (P450) content in fetal and neonatal livers and is the predominant P450 involved in neonatal xenobiotic metabolism. Additionally, it is a key player in healthy birth outcomes through the oxidation of dehydroepiandrosterone (DHEA) and DHEA-sulfate. The amount of the other hepatic CYP3A isoforms, CYP3A4 and CYP3A5, expressed in neonates is low but highly variable, and therefore the activity of individual CYP3A isoforms is difficult to differentiate due to their functional similarities. Consequently, a better understanding of the contribution of CYP3A7 to drug metabolism is essential to identify the risk that drugs may pose to neonates and developing infants. To distinguish CYP3A7 activity from CYP3A4/5, we sought to further characterize the selectivity of the specific CYP3A inhibitors CYP3cide, clobetasol, and azamulin. We used three substrate probes, dibenzylfluorescein, luciferin-PPXE, and midazolam, to determine the IC₅₀ and metabolism-dependent inhibition (MDI) properties of the CYP3A inhibitors. Probe selection had a significant effect on the IC₅₀ values and P450 inactivation across all inhibitory compounds and enzymes. CYP3cide and azamulin were both identified as MDIs and were most specific for CYP3A4. Contrary to previous reports, we found that clobetasol propionate (CP) was not an MDI of CYP3A5 but was more selective for CYP3A5 over CYP3A4/7. We further investigated CYP3cide and CP’s ability to differentiate CYP3A7 activity in an equal mixture of recombinant CYP3A4, CYP3A5, and CYP3A7, and our results provide confidence of CYP3cide’s and CP’s ability to distinguish CYP3A7 activity in the presence of the other CYP3A isoforms.

SIGNIFICANCE STATEMENT

These findings provide valuable insight regarding in vitro testing conditions to investigate the metabolism of new drug candidates and help determine drug safety in neonates. The results presented here also clearly demonstrate the effect that probe selection may have on CYP3A cytochrome P450 inhibition studies.

α-Synuclein (α-Syn) aggregation in Lewy bodies and Lewy neurites has emerged as a key pathogenetic feature in Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy. Various factors, including posttranslational modifications (PTMs), can influence the propensity of α-Syn to misfold and aggregate. PTMs are biochemical modifications of a protein that occur during or after translation and are typically mediated by enzymes. PTMs modulate several characteristics of proteins including their structure, activity, localization, and stability. α-Syn undergoes various posttranslational modifications, including phosphorylation, ubiquitination, SUMOylation, acetylation, glycation, O-GlcNAcylation, nitration, oxidation, polyamination, arginylation, and truncation. Different PTMs of a protein can physically interact with one another or work together to influence a particular physiological or pathological feature in a process known as PTMs crosstalk. The development of detection techniques for the cooccurrence of PTMs in recent years has uncovered previously unappreciated mechanisms of their crosstalk. This has led to the emergence of evidence supporting an association between α-Syn PTMs crosstalk and synucleinopathies. In this review, we provide a comprehensive evaluation of α-Syn PTMs, their impact on misfolding and pathogenicity, the pharmacological means of targeting them, and their potential as biomarkers of disease. We also highlight the importance of the crosstalk between these PTMs in α-Syn function and aggregation. Insight into these PTMS and the complexities of their crosstalk can improve our understanding of the pathogenesis of synucleinopathies and identify novel targets of therapeutic potential.

Significance Statement

α-Synuclein is a key pathogenic protein in Parkinson’s disease and other synucleinopathies, making it a leading therapeutic target for disease modification. Multiple posttranslational modifications occur at various sites in α-Synuclein and alter its biophysical and pathological properties, some interacting with one another to add to the complexity of the pathogenicity of this protein. This review details these modifications, their implications in disease, and potential therapeutic opportunities.

Palliative care pertains to the holistic multidimensional concept of "patient-centred" care. It is an interprofessional specialty, primarily aiming to improve quality of care for cancer patients and their families, from the time of diagnosis of malignant disease, over the continuum of cancer care, and extending after the patient's death to the period of bereavement to support the patient's family. There are various complex and frequently unmet needs of lung cancer patients and their families/caregivers, not only physical but also psychological, social, spiritual and cultural. Systematic monitoring of patients’ symptoms using validated questionnaires and patient-reported outcomes (PROs), on a regular basis, is highly encouraged and recommended in recent guidelines on the role of PRO measures in the continuum of cancer clinical care. It improves patient–physician communication, physician awareness of symptoms, symptom control, patient satisfaction, health-related quality of life and cost-effectiveness. This implies that all treating physicians should improve their skills in communication with lung cancer patients/relatives and become more familiar with this multidimensional assessment, repeatedly screening patients for palliative care needs. Therefore, they should receive education and training to develop palliative care knowledge, skills and attitudes. This review is dedicated to lung cancer palliative care essentials that should be within the competences of treating physicians, i.e. pneumologists/thoracic oncologists.

Massachusetts Air National Guard member Jack Teixeira received a 15-year sentence in federal prison for leaking classified military documents on Discord in a Boston federal court, according to The Washington Post.

Teixeira appeared before the court earlier today and asked the judge for leniency. He also issued a statement apologizing for “all of the harm that I’ve caused, to my friends, family and those overseas.”

Defense attorney Michael Bachrach also claimed that Teixeira was subjected to bullying in high school and his military unit as an adjudicating factor for his actions. Judge Indira Talwani didn’t buy the defense’s bullying claims stating that the Air Force has already disciplined 15 other members connected to Teixeira for not taking more actions “that might have stopped him from doing this.”

Teixeira shared classified military documents as far back as late 2022 on a Discord server dedicated to the pixelated sandbox game Minecraft. The leak included information about the Ukrainian and Russian troop movements and military equipment used in the war in Ukraine and Russia's attempts to obtain more weapons from Egypt and Turkey. The documents eventually found their way to other Discord servers as well as 4chan and Telegram.

FBI officials arrested Teixeira at his home in April of last year. Teixeira originally agreed to a plea deal with federal prosecutors in March that included a 16-year prison sentence for pleading guilty to six counts of willful retention and transmission of national defense information and violating the Espionage Act. If he stuck with his not guilty plea and received a guilty verdict, Teixeira faced a much steeper maximum prison term of 60 years.

A new survey of plan sponsors sheds light on their satisfaction with transparency at large and small pharmacy benefit managers (PBMs).

As you will see, clients remain slightly more satisfied with the perceived transparency of smaller PBMs compared with the Big Three PBMs—CVS Caremark, Express Scripts, and Optum Rx.

However, plan sponsors are dissatisfied with transparency about how both large and small PBMs make money. Smaller PBMs have an edge, but it’s narrower than you might think.

Perhaps PBMs’ clients are unable or unwilling to negotiate better deals, write more effective contracts, and switch to more satisfying relationships. Or maybe they don’t mind the current system, despite the challenges for patients. Some argue that transparency could swoop down to solve this problem. Riddle me this: Should we watch what plan sponsors say, or what they do?
