RESUMEN

States have long used economic sanctions in response to violations of international law as a strategy to restore order. Increasingly, firms also reject doing business with violators. In response to the war in Ukraine, hundreds of multinational corporations voluntarily withdrew from Russia, even when policymakers were still debating the extent of sanctions. How did firm managers evaluate whether to withdraw from the Russian market? Using a survey experiment with Japanese firm managers conducted three months after the Russian invasion of Ukraine in 2022, we explore how peer effects-information on what other firms are doing in response to the crisis-influence support for withdrawal of business activity with Russia. Our findings show that information about withdrawal by other firms from a diverse set of countries promotes peer conformity that increases support. In contrast, information about ongoing business with Russia by Chinese firms fosters competition that reduces support. Market exposure moderates these reactions, although the concern about peer behavior does not appear to be driven by a reputation mechanism. Our research provides insight into how business actors perceive the strategic interplay of peer influence and market dynamics in the context of geopolitical conflicts.

RESUMEN

A portable toilet manufacturer in northwest Indiana (USA) released polyethylene microplastic (MP) pollution into a protected wetland for at least three years. To assess the loads, movement, and fate of the MPs in the wetland from this point source, water and sediment samples were collected in the fall and spring of 2021-2023. Additional samples, including sediment cores and atmospheric particulates, were collected during the summer of 2023 from select areas of the wetland. The MPs were isolated from the field samples using density separation, filtration, and chemical oxidation. Infrared and Raman spectroscopy analyses identified the MPs as polyethylene, which were quantified visually using a stereomicroscope. The numbers of MPs in 100 mL of the marsh water closest to the source ranged from several hundred to over 400,000, while the open water samples contained few microplastics. Marsh surface sediments were highly contaminated with MPs, up to 18,800 per 30.0 g dry mass (dm), compared to core samples in the lower depths (>15 cm) that contained only smaller MPs (<200 µm), numbering 0-480 per 30.0 g (dm). The wide variations in loads of MP contaminants indicate the influence of numerous factors, such as proximity to the point source pollution, weather conditions, natural matter, and pollution sinks, namely sediment deposition. As proof of concept, we demonstrated a novel remediation method using these real-world samples to effectively agglomerate and remove MPs from contaminated waters.

RESUMEN

This study considers the multigenerational consequences of wealth transmission for the transition to young adulthood. Using a wider set of outcomes than has previously been considered, and by analyzing parental and grandparental wealth simultaneously, this work underscores the salience of multiple generations of wealth as a predictor for young adult well-being. Data comes from the US Panel Study of Income Dynamics on a sample of youth followed from mid-adolescence until the age of 20. Results from linear regression models indicate that parental wealth was associated with increases in the probability of college attendance and steady employment and inversely associated with the likelihood of nonmarital birth and idleness. Grandparental wealth predicted non-educational outcomes at least as well as parental wealth did and explained more variance in young adults' outcomes when parental wealth was lower. The association between parental wealth and non-educational outcomes suggest that wealth may inform young adults' broader life course by predicting outcomes other than college attendance. Grandparental wealth may serve a compensatory function for children with low parental wealth. Results suggest that persistently low wealth across multiple generations may impede the successful transition to young adulthood.

RESUMEN

Actinobacteria, the bacterial phylum most renowned for natural product discovery, has been established as a valuable source for drug discovery and biotechnology but is underrepresented within accessible genome and strain collections. Herein, we introduce the Natural Products Discovery Center (NPDC), featuring 122,449 strains assembled over eight decades, the genomes of the first 8490 NPDC strains (7142 Actinobacteria), and the online NPDC Portal making both strains and genomes publicly available. A comparative survey of RefSeq and NPDC Actinobacteria highlights the taxonomic and biosynthetic diversity within the NPDC collection, including three new genera, hundreds of new species, and ~7000 new gene cluster families. Selected examples demonstrate how the NPDC Portal's strain metadata, genomes, and biosynthetic gene clusters can be leveraged using genome mining approaches. Our findings underscore the ongoing significance of Actinobacteria in natural product discovery, and the NPDC serves as an unparalleled resource for both Actinobacteria strains and genomes.

RESUMEN

Background: Pigmented skin lesions in human adults can present with several different visible features that may indicate signs of malignancy, particularly melanoma. Patient and clinician awareness of these features can aid the early recognition and melanoma diagnosis improving patient outcomes. The seven-point checklist (7PCL) is a clinical prediction rule advocated by the National Institute for Health Care Excellence to aid the assessment of pigmented skin lesions in primary care to indicate referral for specialist opinion. Objectives: Assess the current evidence to establish which features of the 7PC present more frequently, so public education and clinician assessment can be focused to maximise early diagnosis and minimise referrals of benign lesions. Methods: A systematic review of published evidence identified studies that assessed the seven features of the 7PCL in histologically proven melanomas. Two independent reviewers screened eligible studies and independently extracted data and assessed quality. Results: 112 studies were screened, 20 were assessed in full, seven met the inclusion criteria. 1184 histologically diagnosed melanomas were assessed using the 7PCL. Four studies involved patients assessing 335 melanomas, and three involved clinicians who assessed 849 melanomas. The most common feature identified was a change in size of the lesion, and the least common was inflammation. Conclusions: The most frequently occurring features of melanoma involve shape, size and colour, however focussing on changes in features, rather than irregularity, is more likely to identify early melanoma and increase the accuracy of referrals.

RESUMEN

The COVID-19 pandemic spurred an economic downturn that may have eroded population mental health, especially for renters and homeowners who experienced financial hardship and were at risk of housing loss. Using household-level data from the Census Bureau's Household Pulse Survey (n = 805,223; August 2020-August 2021) and state-level data on eviction/foreclosure bans, we estimated linear probability models with two-way fixed effects to (1) examine links between COVID-related financial hardship and anxiety/depression and (2) assess whether state eviction/foreclosure bans buffered the detrimental mental health impacts of financial hardship. Findings show that individuals who reported difficulty paying for household expenses and keeping up with rent or mortgage had increased anxiety and depression risks but that state eviction/foreclosure bans weakened these associations. Our findings underscore the importance of state policies in protecting mental health and suggest that heterogeneity in state responses may have contributed to mental health inequities during the pandemic.

RESUMEN

Ice streams that flow into Ross Ice Shelf are underlain by water-saturated sediments, a dynamic hydrological system, and subglacial lakes that intermittently discharge water downstream across grounding zones of West Antarctic Ice Sheet (WAIS). A 2.06 m composite sediment profile was recently recovered from Mercer Subglacial Lake, a 15 m deep water cavity beneath a 1087 m thick portion of the Mercer Ice Stream. We examined microbial abundances, used 16S rRNA gene amplicon sequencing to assess community structures, and characterized extracellular polymeric substances (EPS) associated with distinct lithologic units in the sediments. Bacterial and archaeal communities in the surficial sediments are more abundant and diverse, with significantly different compositions from those found deeper in the sediment column. The most abundant taxa are related to chemolithoautotrophs capable of oxidizing reduced nitrogen, sulfur, and iron compounds with oxygen, nitrate, or iron. Concentrations of dissolved methane and total organic carbon together with water content in the sediments are the strongest predictors of taxon and community composition. δ¹³C values for EPS (-25 to -30‰) are consistent with the primary source of carbon for biosynthesis originating from legacy marine organic matter. Comparison of communities to those in lake sediments under an adjacent ice stream (Whillans Subglacial Lake) and near its grounding zone provide seminal evidence for a subglacial metacommunity that is biogeochemically and evolutionarily linked through ice sheet dynamics and the transport of microbes, water, and sediments beneath WAIS.

RESUMEN

This study broadens the traditional focus on income as the primary measure of economic deprivation by providing the first analysis of wealth deprivation, or net worth poverty (NWP), and adult health. Net worth poverty-having wealth (assets minus debts) less than one-fourth of the federal poverty line-likely exacerbates the negative effects of income poverty (IP). In 2019, one-third of US households were net worth poor, with substantially higher rates among Black (60%) relative to White (25%) households. We estimate longitudinal growth curve (i.e., linear mixed effects) models to test how NWP, IP, and the interaction of the two predict a diverse set of health measures. We also consider whether NWP resulting from either low assets or high debts is more predictive of health outcomes and test for heterogeneous associations by race. Data come from Panel Study of Income Dynamics on 8,962 individuals ages 25 to 64, observed between 2011 and 2019 (n = 26,776). Adjusting for income poverty, net worth poverty, relative to no poverty, was associated with a one-quarter to one-third increase in the likelihood of reporting poor self-rated health, psychological distress, and work limitations. Simultaneously experiencing both NWP and IP was associated with the largest deficits. Both asset-driven (low asset) and debt-driven (high debt) NWP reduced health, but asset-driven NWP had stronger associations (e.g., a 5-percentage point increase of being in poor health, twice that of debt-driven). White, relative to Black, adults exhibited statistically larger associations for psychological distress (4.3 vs 1.1 percentage points) and work limitations (3.7 vs. 1.5 percentage points). White and Black adults who were jointly net worth and income poor exhibited the most disadvantage. Findings underscore how wealth is a critical component of financial deprivation and that wealth deprivation, particularly the lack of assets, merits attention in socioeconomic studies of health inequalities.

RESUMEN

Perceived stress, a known risk factor for poor health, has been extensively assessed in adult populations. Yet an equivalent assessment tool for measurement of global perceived stress in children is lacking. This study aimed to develop and provide initial validation of a scale to measure perceived stress in children aged 7-11 years. Using a two-phase design, we conducted semi-structured interviews with thirteen child-parent dyads for development of items. In a sample of 123 children (age range 7-11 years, Mage = 9 years 7 months, 54.5% male) we administered the resulting Perceived Stress Scale for Kids (PeSSKi). Exploratory factor analysis of the 10-item PeSSKi yielded support for both a one-factor and a two-factor solution (negative, positive item wording). The PeSSKi was associated positively with the Penn-State Worry Questionnaire for Children (r = 0.748, p < 0.001) and negatively with the Students' Life Satisfaction Scale (r = 0.381, p < 0.001) indicating strong convergent/divergent validity respectively. Girls showed higher scores on the PeSSKi than boys with no effects observed by age. Initial psychometrics suggest the PeSSKi provides a robust scale for assessment of perceived stress in children. Further validation is needed across different child populations, over time and with physical measures of stress and health outcomes.

RESUMEN

BACKGROUND AND OBJECTIVES: Graft failure (GF) after cord blood transplant (CBT) has decreased with improved supportive care and cord selection strategies. We aimed to evaluate cord blood selection and factors associated with retransplantation on the incidence of GF, determine risk factors for GF including host antibodies to Kell antigen and evaluate survival after GF. MATERIALS AND METHODS: We retrospectively reviewed 84 patients who underwent CBT at the University of Oklahoma between 2000 and 2016 and compared outcomes in patients with/without engraftment by Day 28. The nonengraftment cohort was further divided into patients who underwent retransplantation. Kaplan-Meier curves with log-rank tests were calculated to assess the association between mortality and engraftment. RESULTS: Engraftment following CBT was high at 81%, with 52% engrafting by Day 28 and an additional 29% engrafting by a median of 36 days. Retransplantation led to 88% engraftment at a median of 53 days. Overall, 75% of the 40 patients who did not engraft by Day 28 died. Female sex and total nucleated cell count < 3.5/kg were significantly associated with lack of engraftment and higher mortality. Antibodies to Kell fetal antigen were not identified. Retransplantation by Day 28 for primary GF conferred a survival advantage. CONCLUSION: This study demonstrates that failure to engraft by 28 days was associated with increased mortality, and risk was mitigated with early retransplantation. Female sex and low total cell dose were associated with increased mortality. Early identification of GF coupled with early retransplantation can reduce mortality in CBT.

RESUMEN

Evidence on how parenthood impacts household wealth in the United States has been inconclusive, partially because previous studies have decontextualized parenthood from gender, marital, and relationship status. Yet, insights from economic sociology suggest that wealth-related behaviors are shaped by the intersection of identities, not by a binary classification of parental status. We examine net worth by the intersection of gender, parental, and relationship status during a period of increasing wealth inequality and family diversification. Using data from the Survey of Consumer Finances from 1989 through 2019, we show that aggregate comparisons between parents and non-parents mask substantial wealth variation across nine household types. Despite changing social selection into marriage and parenthood, married parents consistently held a wealth advantage over demographically similar adults in other household types. Married parents' wealth advantage descriptively arises from homeownership, perhaps because the combined spousal and parental identities are normatively and culturally associated with homeownership.

RESUMEN

Basal cell carcinoma (BCC) is the most common malignancy worldwide. Fortunately, most tumors are localized and easily amenable to surgical resection or locally destructive treatments. However, a subset of BCCs can become locally advanced or metastatic. The development of small-molecule inhibitors of smoothened, a protein in the hedgehog pathway, which is almost universally activated in BCCs, was a breakthrough in the treatment of patients with advanced BCC. However, these agents are associated with primary and secondary resistance and have a toxicity profile that makes long-term use difficult. The recent approval of cemiplimab for patients with advanced BCC who are resistant to or are intolerant of hedgehog inhibitor therapy fills a significant unmet need as these patients now have a viable, second-line systemic therapeutic option. This article summarizes the rationale and data leading to the approval for cemiplimab in advanced BCC.

RESUMEN

The authors investigate whether net worth poverty (NWP) reduces children's well-being. NWP-having wealth (assets minus debts) less than one fourth of the federal poverty line-is both theoretically and empirically distinct from income poverty (IP) and is the modal form of poverty among children. Data come from the Panel Study of Income Dynamics and its Child Development Supplement on children ages 3 to 17 years observed between 2002 and 2019. The authors use linear mixed-effects models to investigate the associations among NWP, IP, and four cognitive and behavioral outcomes. NWP reduces children's cognitive scores and was associated with increases in both problem behavior scores. Negative associations for NWP are similar in magnitude to those found for IP. Much of the NWP effect operates through asset deprivation rather than high debt. The results illustrate the potential risks many children, previously overlooked in studies of IP, face because of wealth deprivation.

RESUMEN

OBJECTIVE: This study is the first to examine net worth poverty, and its intersection with income poverty, by race and ethnicity among child households in the United States. BACKGROUND: Scholarship on economic scarcity for children has largely concentrated on income deficits and thus leaves open important questions about wealth deficits. METHOD: Data come from the 1989-2019 waves of the Survey of Consumer Finances, on households with at least one resident child under the age of 18. Net worth poverty is measured as household net worth, defined as total assets minus total debts, that is less than one-fourth of the federal poverty line. RESULTS: In 2019, 57% of Black and 50% of Latino child households were net worth poor. The majority of these households were not income poor. Racial and ethnic differences in net worth poverty (unlike those for income poverty) persist even when sociodemographic variation predicting income poverty is controlled for. CONCLUSION: Net worth poverty is so prevalent in the lives of non-White children that, after sociodemographic characteristics are controlled for, Black and Latino child households have about the same probability of not being poor as they do of being net worth poor. IMPLICATIONS: A focus on income deprivation alone will overlook the precarious economic conditions related to family net worth and ignore growing disparities by race and ethnicity.

RESUMEN

In response to the COVID-19 pandemic, immediate and scalable testing solutions are needed to direct return to full capacity planning in the general public and across the Department of Defense (DoD). To fully understand the extent to which a population has been affected by COVID-19, active monitoring approaches require an estimation of overall seroprevalence in addition to accurate, affordable, and rapid tests to detect current SARS-CoV-2 infection. In this study, researchers in the Air Force Research Laboratory's 711th Human Performance Wing, Airman Systems Directorate evaluated the performance of various testing methods for the detection of SARS-CoV-2 antibodies and viral RNA in asymptomatic adults working at Wright-Patterson Air Force Base and the surrounding area during the period of 23 July 2020-23 Oct 2020. Altogether, there was a seroprevalance of 3.09% and an active infection rate of 0.5% (determined via the testing of saliva samples) amongst individuals tested, both of which were comparable to local and national averages at the time. This work also presents technical and non-technical assessments of various testing strategies as compared to the gold standard approaches (e.g., lateral flow assays vs. ELISA and RT-LAMP vs. RT-PCR) in order to explore orthogonal supply chains and fieldability. Exploration and validation of multiple testing strategies will allow the DoD and other workforces to make informed responses to COVID-19 and future pandemics.

RESUMEN

We examine how increased Immigration and Customs Enforcement (ICE) activities impacted newborn health and prenatal care utilization in North Carolina around the time Section 287(g) of the Immigration and Nationality Act was first being implemented within the state. Focusing on administrative data between 2004 and 2006, we conduct difference-in-differences and triple-difference case-control regression analysis. Pregnancies were classified by levels of potential exposure to immigration enforcement depending on parental nativity and educational attainment. Contrast groups were foreign-born parents residing in nonadopting counties and all US-born non-Hispanic parents. The introduction of the program was estimated to decrease birth weight by 58.54 grams (95% confidence interval [CI], -83.52 to -33.54) with effects likely following from reduced intrauterine growth. These results are shown to coexist with a worsening in the timing of initiation and frequency of prenatal care received. Since birth outcomes influence health, education, and earnings trajectories, our findings suggest that the uptick in ICE activities can have large socioeconomic costs over US-born citizens.

RESUMEN

Hispanic families have historically used means-tested assistance less than high-poverty peers, and one explanation for this may be that anti-immigrant politics and policies are a barrier to program participation. We document the participation of Hispanic children in three antipoverty programs by age and parental citizenship and the correlation of participation with state immigrant-based restrictions. Hispanic citizen children with citizen parents participate in Supplemental Nutrition Assistance Program (SNAP) and Medicaid more than Hispanic citizen children with noncitizen parents. Foreign-born Hispanic mothers use Medicaid less than their socioeconomic status would suggest. However, little evidence exists that child participation in Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) varies by mother's nativity: foreign-born mothers of Hispanic infants participate in WIC at higher rates than U.S.-born Hispanic mothers. State policies that restrict immigrant program use correlate to lower SNAP and Medicaid uptake among citizen children of foreign-born Hispanic mothers. WIC participation may be greater because it is delivered through nonprofit clinics, and WIC eligibility for immigrants is largely unrestricted.

RESUMEN

Engineered probiotics are the next generation of live biotherapeutics that have been genetically modified to target specific diseases. With the advancements in synthetic biology, the engineering of probiotics has become increasingly sophisticated which has led to the development of therapies for treating cancer, infection, metabolic disorders and inflammation, as well as for diagnosing and preventing them. Herein, we review some of the recent examples of probiotics which have been engineered to target such diseases. Although there are numerous examples of engineered probiotics showing efficacy in animal models, there are no approved products on the market with very few in clinical trials. Therefore, we also discuss a set of features that may be incorporated into engineered probiotics to aid in clinical translation and ultimately, realizing the potential of these biotherapeutics.
