RESUMEN
The nucleus is highly compartmentalized through the formation of distinct classes of membraneless domains. However, the composition and function of many of these structures are not well understood. Using APEX2-mediated proximity labeling and RNA sequencing, we surveyed human transcripts associated with nuclear speckles, several additional domains, and the lamina. Remarkably, speckles and lamina are associated with distinct classes of retained introns enriched in genes that function in RNA processing, translation, and the cell cycle, among other processes. In contrast to the lamina-proximal introns, retained introns associated with speckles are relatively short, GC-rich, and enriched for functional sites of RNA-binding proteins that are concentrated in these domains. They are also highly differentially regulated across diverse cellular contexts, including the cell cycle. Thus, our study provides a resource of nuclear domain-associated transcripts and further reveals speckles and lamina as hubs of distinct populations of retained introns linked to gene regulation and cell cycle progression.

The evolution of innate behaviours is ultimately due to genetic variation likely acting in the nervous system. Gene regulation may be particularly important because it can evolve in a modular brain-region specific fashion through the concerted action of cis- and trans-regulatory changes. Here, to investigate transcriptional variation and its regulatory basis across the brain, we perform RNA sequencing (RNA-Seq) on ten brain subregions in two sister species of deer mice (Peromyscus maniculatus and P. polionotus)-which differ in a range of innate behaviours, including their social system-and their F1 hybrids. We find that most of the variation in gene expression distinguishes subregions, followed by species. Interspecific differential expression (DE) is pervasive (52-59% of expressed genes), whereas the number of DE genes between sexes is modest overall (~3%). Interestingly, the identity of DE genes varies considerably across brain regions. Much of this modularity is due to cis-regulatory divergence, and while 43% of genes were consistently assigned to the same gene regulatory class across subregions (e.g. conserved, cis- or trans-regulatory divergence), a similar number were assigned to two or more different gene regulatory classes. Together, these results highlight the modularity of gene expression differences and divergence in the brain, which may be key to explain how the evolution of brain gene expression can contribute to the astonishing diversity of animal behaviours.
RESUMEN
Optical water classification based on remote sensing reflectance (Rrs(λ)) data can provide insight into water components driving optical variability and inform the development and application of bio-optical algorithms in complex aquatic systems. In this study, we use an in situ dataset consisting of hyperspectral Rrs(λ) and other biogeochemical and optical parameters collected over nearly five years across a heavily urbanized estuary, the Long Island Sound (LIS), east of New York City, USA, to optically classify LIS waters based on Rrs(λ) spectral shape. We investigate the similarities and differences of discrete groupings (k-means clustering) and continuous spectral indexing using the Apparent Visible Wavelength (AVW) in relation to system biogeochemistry and water properties. Our Rrs(λ) dataset in LIS was best described by three spectral clusters, the first two accounting for the majority (89%) of Rrs(λ) observations and primarily driven by phytoplankton dynamics, with the third confined to measurements in river and river plume waters. We found AVW effective at tracking subtle changes in Rrs(λ) spectral shape and fine-scale water quality features along river-to-ocean gradients. The recently developed Quality Water Index Polynomial (QWIP) was applied to evaluate three different atmospheric correction approaches for satellite-derived Rrs(λ) from the Sentinel-3 Ocean and Land Colour Instrument (OLCI) sensor in LIS, finding Polymer to be the preferred approach. Our results suggest that integrative, continuous indices such as AVW can be effective indicators to assess nearshore biogeochemical variability and evaluate the quality of both in situ and satellite bio-optical datasets, as needed for improved ecosystem and water resource management in LIS and similar regions.

BACKGROUND: For over 20 years, the United States has suffered the detrimental effects of an opioid epidemic. Extended-release opioid products are particularly prone to abuse due to the high amount of opioid present. By bypassing the controlled-release mechanisms and nonoral administration, individuals experience intense and dangerous "highs." Abuse-deterrent opioid formulations have been recommended as a potential solution to the crisis, but widespread utilization has been stunted and their role in therapy remains unclear owing to limited real-world efficacy data and affordability issues. This review discusses abuse-deterrent opioid formulations, the mechanisms and data underlying available products, and a pharmacist's perspective of their role in the opioid crisis. METHODS: The authors reviewed PubMed, MEDLINE, and Google Scholar electronic databases for premarketing and postmarketing studies on OxyContin, Xtampza ER, and Hysingla ER. RESULTS: Studies showed lower rates of abuse (19% reduction), opioid use disorder (27%), overdose (34%), and fatalities (85%) with the reformulated OxyContin when compared with the original product and comparator opioids. However, these studies revealed the potential for bypassing abuse-deterrent mechanisms and diverting abuse to other drugs. Postmarketing studies are unavailable for Xtampza ER or Hysingla ER, although premarketing studies suggested that some controlled-release properties persist when the product is manipulated, indicating that abuse may be more difficult and less rewarding. CONCLUSIONS: Abuse-deterrent opioid products may lead to reductions in abuse, overdose, and overdose fatalities. However, cost, loopholes in deterrence mechanism, and possible diversion to other substances hinder their role in the opioid crisis. Multiple approaches must be used to improve opioid safety, and further postmarketing and real-world analyses should be performed on available opioid formulations to assess their impact on abuse-related adverse events.

In plant-animal mutualisms, how an animal forages often determines how much benefit its plant partner receives. In many animals, foraging behaviour changes in response to foraging gene expression or activation of the cGMP-dependent protein kinase (PKG) that foraging encodes. Here, we show that this highly conserved molecular mechanism affects the outcome of a plant-animal mutualism. We studied the two PKG genes of Allomerus octoarticulatus, an Amazonian ant that defends the ant-plant Cordia nodosa against herbivores. Some ant colonies are better 'bodyguards' than others. Working in the field in Peru, we found that colonies fed with a PKG activator recruited more workers to attack herbivores than control colonies. This resulted in less herbivore damage. PKG gene expression in ant workers correlated with whether an ant colony discovered an herbivore and how much damage herbivores inflicted on leaves in a complex way; natural variation in expression levels of the two genes had significant interaction effects on ant behaviour and herbivory. Our results suggest a molecular basis for ant protection of plants in this mutualism.

NEW FINDINGS: What is the central question of this study? What are the individual and combined effects of muscle-specific peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) overexpression and physical activity during high-fat feeding on glucose and exercise tolerance? What is the main finding and its importance? Our main finding is that muscle-specific PGC-1α overexpression provides no protection against lipid-overload pathologies nor does it enhance exercise adaptations. Instead, physical activity, regardless of PGC-1α content, protects against high-fat diet-induced detriments. Activation of muscle autophagy was correlated with exercise protection, suggesting that autophagy might be a mediating factor for exercise-induced protection from lipid overload. The prevalence of glucose intolerance is alarmingly high. Efforts to promote mitochondrial biogenesis through peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) to mitigate glucose intolerance have been controversial. However, physical activity remains a primary means to alleviate the condition. The aim of this study was to determine the combined effects of muscle-specific overexpression of PGC-1α and physical activity on glucose handling during diet-induced obesity. Wild-type (WT, â¼20) and PGC-1α muscle transgenic (MCK-PGC-1α, â¼20) mice were given a Western diet (WD) at 8 weeks age and allowed to consume food ab libitum throughout the study. At 12 weeks of age, all animals were divided into sedentary (SED) or voluntary wheel running (VWR) interventions. At 7, 11 and 15 weeks of age, animals underwent glucose tolerance tests (GTT) and graded exercise tests (GXT). At 16 weeks of age, tissues were collected. At 11 weeks, the MCK-PGC-1α animals had 50% greater glucose tolerance integrated area under the curve compared with WT. However, at 15 weeks, SED animals also had greater GTT integrated area under the curve compared with VWR, regardless of genotype; furthermore, SED animals demonstrated reduced exercise capacity compared with earlier time points, which was not seen in VWR animals. Voluntary distance run per day was correlated with GTT in VWR-WT, but not VWR-MCK-PGC-1α mice. Voluntary wheel running and genotype independently resulted in a greater LC3II/LC3I ratio, suggesting enhanced autophagosome formation, which was correlated with exercise-induced improvements in GTT. In conclusion, artificially increasing mitochondrial content does not protect from lipid-induced pathologies nor does it augment exercise adaptations. Physical activity ameliorates the effects of lipid overload-induced glucose intolerance, an effect that appears to be related to enhanced activation of autophagy.

Since leadership development was first included in the 2013 Center for the Advancement of Pharmacy Education (CAPE) Educational Outcomes as a desired outcome of pharmacy curricula, pharmacy educators have embraced leadership development as a desired outcome of pharmacy professional programs. As we gain experience and as circumstances change, educators must consider whether our current strategies for preparing leaders will meet the needs of an ever evolving and deeply complex practice environment. The aim of this review is to encourage educators to reconsider our investments in leadership development and leader development. Using an analogy between carpentry and leader development, we argue for a rebalancing of our efforts. Leaning on Day, Harrison and Halpin's Integrative Theory of Leader Development, we summarize Expert Performance and Skill Acquisition, Identity and Self-Regulation, and Adult Development theories. Each of these three theories provides educators with variables to consider as we seek to design a system to support leader development. Our traditional practices of teaching leadership are challenged by this deeper understanding of how leaders develop. Sustainable leader development requires a longitudinal perspective with a focus on individualized support, and a growth orientation. Practical implications of committing to leader development include educators: serving as coaches rather than content experts, creating space for intentional practice and critical reflection, and adapting traditional structures and resources for faculty involved in leader development initiatives. A deeper understanding of the process of leader development will set students on a lifelong trajectory of leading, which will benefit the profession for years to come.
RESUMEN
Infectious mononucleosis (IM) is a viral illness caused by the Epstein-Barr virus that typically manifests with pharyngitis, lymphadenopathy, and fatigue. In rare cases, IM can cause acute appendicitis. We present the case of an 18-year-old female who arrived at the emergency department with worsening abdominal pain and an ongoing cough. Initial imaging showed a questionably dilated appendix, and a follow-up examination revealed cervical lymphadenopathy. She later returned to the ED with severe abdominal pain, clinical signs of acute appendicitis, and a positive monospot test, which led to an appendectomy. This case illustrates the need for complete history taking and thorough physical examination in patients with acute appendicitis, as their condition may be due to an atypical underlying cause.
RESUMEN
Variation in the size and number of axial segments underlies much of the diversity in animal body plans. Here we investigate the evolutionary, genetic and developmental mechanisms driving tail-length differences between forest and prairie ecotypes of deer mice (Peromyscus maniculatus). We first show that long-tailed forest mice perform better in an arboreal locomotion assay, consistent with tails being important for balance during climbing. We then identify six genomic regions that contribute to differences in tail length, three of which associate with caudal vertebra length and the other three with vertebra number. For all six loci, the forest allele increases tail length, indicative of the cumulative effect of natural selection. Two of the genomic regions associated with variation in vertebra number contain Hox gene clusters. Of those, we find an allele-specific decrease in Hoxd13 expression in the embryonic tail bud of long-tailed forest mice, consistent with its role in axial elongation. Additionally, we find that forest embryos have more presomitic mesoderm than prairie embryos and that this correlates with an increase in the number of neuromesodermal progenitors, which are modulated by Hox13 paralogues. Together, these results suggest a role for Hoxd13 in the development of natural variation in adaptive morphology on a microevolutionary timescale.

This study evaluated water quality, nitrogen (N), and phytoplankton assemblage linkages along the western Long Island Sound (USA) shoreline (Nov. 2020-Dec. 2021) following COVID-19 stay-in-place (SIP) orders through monthly surveys and N-addition bioassays. Ammonia-N (AmN; NH3+NH4+) negatively correlated with total chlorophyll-a (chl-a) at all sites; this was significant at Alley Creek, adjacent to urban wastewater inputs, and at Calf Pasture, by the Norwalk River (Spearman rank correlation, p < 0.01 and 0.02). Diatoms were abundant throughout the study, though dinoflagellates (Heterocapsa, Prorocentrum), euglenoids/cryptophytes, and both nano- and picoplankton biomass increased during summer. In field and experimental assessments, high nitrite + nitrate (N + N) and low AmN increased diatom abundances while AmN was positively linked to cryptophyte concentrations. Likely N + N decreases with presumably minimal changes in AmN and organic N during COVID-19 SIP resulted in phytoplankton assemblage shifts (decreased diatoms, increased euglenoids/cryptophytes), highlighting the ecological impacts of N-form delivered by wastewater to urban estuaries.

Men who have sex with men are an important yet marginalised population for HIV prevention in Africa. We conducted a two-phase study (individual qualitative interviews and a survey) of men who have sex with men, aged 18-34 years of age and living in Kisumu, Kenya. Approximately half (27/51) of survey respondents reported belonging to a support group. The odds of belonging to support groups were greater for older men (aged 24-34 versus 18-23 years [OR = 5.20; 95% CI = 1.27-26.66]). More than two-thirds (68.6%) of survey respondents were categorised as having high knowledge of HIV-risk factors. Most respondents (94.1%) correctly reported lack of condom use during vaginal sex as a risk factor for HIV, but slightly fewer (82.4%) recognised lack of condom use during anal sex as an HIV risk factor. Among the 15 interviewees, the following were included as greatest needs: health information (n = 5), safe lubricants (n = 5), condoms (n = 4), healthcare facility or men-who-have-sex-with-men-friendly health services (n = 3) and advocacy (n = 2). Kenyan men who have sex with men have developed support groups and have unmet needs for information, lubricants and condoms and services. Partnering with support groups offers an opportunity for organisations to reach men who have sex with men with accurate health information, provision of safe sexual lubricants, condoms and other health and social services.

PURPOSE: With expanding roles of clinic-embedded pharmacists comes the need to identify routes for optimization, soliciting and addressing feedback, and justifying the position(s) to the employing institution. Studies have demonstrated the benefit of integrating pharmacists into healthcare teams, but these opportunities remain largely limited to major health systems due to a lack of billing avenues for and familiarity with the services pharmacists can provide. METHODS: With funding from and partnership with a third-party payor, a pharmacist was incorporated into a private physician-owned clinic to be a resource to the providers and provide comprehensive medication management to patients. Patient and provider experiences were assessed by survey and interview, respectively, utilizing both Likert-scale and free-response questions. The responses were coded, analyzed, and aggregated into themes. The demographic and Likert-scale responses were analyzed using descriptive statistics. RESULTS: Patients reported a high level of satisfaction with the pharmacist's service, indicating that they felt more comfortable managing their medications and that they would recommend the pharmacist to a family member or friend. Provider satisfaction was also high, with providers stating that they found the recommendations by the pharmacist helpful, that the recommendations improved cardiovascular risk factors in their patients with diabetes, and that, overall, they were satisfied with the care provided by the pharmacist. The primary concern from the providers was a lack of understanding regarding how best to reach and utilize the service. CONCLUSION: Overall, an embedded clinical pharmacist providing comprehensive medication management at a private primary care clinic had a positive impact on both provider and patient satisfaction.

The COVID-19 pandemic altered human mobility, particularly in large metropolitan areas. In New York City (NYC), stay-at-home orders and social distancing led to significant decreases in commuting, tourism, and a surge of outward migration. Such changes could result in decreased anthropogenic pressure on local environments. Several studies have linked COVID-19 shutdowns with improvements in water quality. However, the bulk of these studies primarily focused on short-term impacts during shutdown periods, without assessing longer-term impacts as restrictions eased. Here, we examine both concurrent lockdown and societal reopening impacts on water quality, using pre-pandemic baseline conditions, in two highly urbanized estuaries surrounding NYC, the New-York Harbor estuary and Long Island Sound (LIS). We compiled datasets from 2017 to 2021 of mass-transit ridership, work-from-home trends, and municipal wastewater effluent to assess changes in human mobility and anthropogenic pressure during multiple waves of the pandemic in 2020 and 2021. These were linked to changes in water quality assessed using high spatiotemporal ocean color remote sensing, which provides near-daily observations across the estuary study regions. To distinguish anthropogenic impacts from natural environmental variability, we examined meteorological/hydrological conditions, primarily precipitation and wind. Our results show that nitrogen loading into the New York Harbor declined significantly in the spring of 2020 and remained below pre-pandemic values through 2021. In contrast, nitrogen loading into LIS remained closer to the pre-pandemic average. In response, water clarity in New-York Harbor significantly improved, with less of a change in LIS. We further show that changes in nitrogen loading had higher impact on water quality than meteorological conditions. Our study demonstrates the value of remote sensing observations in assessing water quality changes when field-based monitoring is hindered and highlights the complex nature of urban estuaries and their heterogeneous response to changes in extreme events and human behavior.

INTRODUCTION AND LEADERSHIP FRAMEWORK: While the scope of a pharmacist's work has grown, continued advocacy is needed to ensure that their skillset is used to the best advantage of the patient. To accomplish this aim, the University of Utah College of Pharmacy created an elective advocacy and leadership class to train students in leadership and advocacy methods, with a focus on enabling students to practice advocacy within the state of Utah throughout the class. EDUCATIONAL CONTEXT AND METHODS: In addition to traditional lectures, this class asked students to apply the knowledge learned in class to projects within their sphere of influence. Activities included drafting their own bill, writing to a legislator, attending state legislative and board of pharmacy meetings, and a longitudinal quality improvement project. Students answered a pre- and post-class survey to assess their attitudes towards advocacy efforts and how those attitudes were affected by participation in the class. FINDINGS AND DISCUSSION: As expected, a positive change in attitude towards advocacy was observed, and students indicated that they were more likely to engage in advocacy activities in the future after participating in the course. Moreover, a real legislative outcome has been observed as the result of class projects. IMPLICATIONS: Enabling students to engage in advocacy activities and guiding them to effect real change is a valuable technique in pharmacy education. Similar efforts can be replicated in other institutions, and similar training should be expanded to required portions of the pharmacy curriculum.

The American Association of Colleges of Pharmacy recognizes strategic engagement as critical to the success of pharmacy education, contributing to the expansion of pharmacy and public health practice, the fulfillment of institutional missions, and the meeting of programmatic needs. The 2022-2023 Strategic Engagement Committee or the Committee was charged with identifying ways professional advocacy is being emphasized in Doctor of Pharmacy and graduate education curricula to optimize active student engagement and share new resources for the ongoing resource guide being developed by the association. The Committee was also tasked with identifying advocacy champions at each member institution, integrating them into the work of the American Association of Colleges of Pharmacy Policy Advisory Task Force, and identifying strong advocacy partnerships between colleges and schools of pharmacy and state pharmacy organizations that can be replicated to advance the legislative or regulatory priorities of the profession. The Committee conducted a 2-part, sequential advocacy survey to identify advocacy champions at member institutions and to gain better insight into the breadth and depth of current advocacy efforts within pharmacy programs. The Committee also developed suggestions for the advocacy activities that should be required in pharmacy curricula, as well as exemplary activities identified through surveying advocacy champions.

BACKGROUND: Injectable opioid agonist treatment (iOAT) has proven to be a safe and effective treatment option for severe opioid use disorder (OUD). Yet, iOAT is often isolated from other health and social services. To align with a person-centered care approach, iOAT can be embedded in sites that combine systems and services that have been historically fragmented and that address multiple comorbidities (integrated care sites). The present study investigates the addition of iOAT at an integrated care in Vancouver, British Columbia. We aimed to capture what it means for service users and service providers to incorporate iOAT in an integrated care site and describe the processes by which the site keeps people engaged. METHODS: We conducted 22 interviews with 15 service users and 14 interviews with 13 service providers across two rounds of individual semi-structured interviews (Fall 2021, Summer 2022). The second interview round was precipitated by a service interruption in medication dispensation. Interview audio was recorded, transcribed, and then analysed in NVivo 1.6 following an interpretive description approach. RESULTS: The emergent themes from the analysis are represented in two categories: (1) a holistic approach (client autonomy, de-medicalized care, supportive staff relationships, multiple opportunities for engagement, barriers to iOAT integration) and (2) a sense of place (physical location, social connection and community belonging, food). CONCLUSION: Incorporating iOAT at an integrated care site revealed how iOAT delivery can be strengthened through its direct connection to a diverse, comprehensive network of health and social services that are provided in a community atmosphere with high quality therapeutic relationships.

Several studies have demonstrated the benefit of clinical pharmacy services in primary care. However, studies are limited on providers' perceived value of embedded primary care pharmacy teams. The purpose of this project was to determine how primary care clinical pharmacists and technicians provide value to medical providers. Primary care providers in University of Utah health clinics where primary care clinical pharmacists are embedded were invited to participate in one-on-one, semi-structured interviews. Interview sessions were recorded, transcribed, and de-identified. The transcripts were coded and analyzed to determine common themes. Questions were on various topics, including what is of greatest value to them, pharmacy integration into care teams, provider burnout, provider happiness at work, provider workload, and provider retention in the health system. In total, 25 interviews were conducted from nine different clinics (response rates of 19.7% for providers and 81.8% for clinics). Coding revealed themes of increased job satisfaction, enhanced patient care, decreased workload and burnout, and a desire for increased access to clinical pharmacy services. The responses related to clinical pharmacists in primary care were overwhelmingly positive, and providers almost unanimously expressed the need for more pharmacy services in primary care.
RESUMEN
Interannual sea surface temperature (SST) variations in the tropical Atlantic Ocean lead to anomalous atmospheric circulation and precipitation patterns with important ecological and socioeconomic consequences for the semiarid regions of sub-Saharan Africa and northeast Brazil. This interannual SST variability is characterized by three modes: an Atlantic meridional mode featuring an anomalous cross-equatorial SST gradient that peaks in boreal spring; an Atlantic zonal mode (Atlantic Niño mode) with SST anomalies in the eastern equatorial Atlantic cold tongue region that peaks in boreal summer; and a second zonal mode of variability with eastern equatorial SST anomalies peaking in boreal winter. Here we investigate the extent to which there is any seasonality in the relationship between equatorial warm water recharge and the development of eastern equatorial Atlantic SST anomalies. Seasonally stratified cross-correlation analysis between eastern equatorial Atlantic SST anomalies and equatorial heat content anomalies (evaluated using warm water volume and sea surface height) indicate that while equatorial heat content changes do occasionally play a role in the development of boreal summer Atlantic zonal mode events, they contribute more consistently to Atlantic Niño II, boreal winter events. Event and composite analysis of ocean adjustment with a shallow water model suggest that the warm water volume anomalies originate mainly from the off-equatorial northwestern Atlantic, in agreement with previous studies linking them to anomalous wind stress curl associated with the Atlantic meridional mode.
RESUMEN
PURPOSE: As the pharmacist's role expands, particularly in primary care practice settings, there is an opportunity for expansion of pharmacy technician duties to aid in administrative and clinical tasks that do not require the pharmacist's professional judgment. Identifying, defining, and expanding the roles of pharmacy technicians has been deemed a key part of the pharmacy practice model. These roles have been shown to enhance pharmacist efficiency and patient outreach; however, examples of the various innovative activities performed by technicians in the primary care setting are lacking in the literature. METHODS: The duties of primary care pharmacy technicians were compiled and defined in 2 different healthcare systems. The role of the technician was separately implemented at each institution, and study designs and protocols were individually created and executed. One institution utilized a 4-round consensus-building process to systematically refine and codify tasks for a dictionary of duties. The second institution utilized a free-text survey, task documentation data in the electronic medical record, and a telephone discussion with the technicians. RESULTS: Despite a lack of methods- and data-sharing between the 2 institutions, similar tasks were identified, including conducting patient outreach, assisting with medication affordability and access, providing patient education, managing referrals, and scheduling appointments. Differences in technician involvement were noted in areas such as prior authorization, care coordination meetings, and quality improvement projects. CONCLUSION: Pharmacy technicians are a helpful, yet underutilized, resource in the primary care setting. Further exploration of technician roles is needed to determine the financial and clinical impact of expanding these roles.
