RESUMO

The timing and structure of fertility have important implications for individuals and society. Families play a critical role in fertility; however, little is known about how parental incarceration shapes fertility despite it being a common experience in the life course of disadvantaged children. This study examines the consequences of parental incarceration for children's fertility using the National Longitudinal Survey of Youth 1997. I employ multiple-decrement life tables and survival analyses to estimate the relationship between parental incarceration and fertility. Individuals who experience parental incarceration have different timing of fertility, with earlier first births and a quicker pace of subsequent births, as well as more nonmarital fertility, compared with those who do not experience parental incarceration. This analysis finds consistent evidence that parental incarceration is associated with the timing and structure of fertility and suggests that a parent's incarceration carries consequences over the life course of children. This study advances our understanding of how mass incarceration shapes American families, illustrates how the broader consequences of mass incarceration contribute to social inequality, and provides evidence that the enduring implications of incarceration span multiple generations.

RESUMO

The transition to adulthood is an important process with implications for inequality. Both those with disabilities and those who age of out of foster care are vulnerable during this transition. This project examines the intersection of these groups, exploring employment, education, and disability benefit receipt, the supports these youth receive, and how these supports may mitigate risk in this transition. Findings suggest that those with emotional or mental disabilities face employment risks in the transition to adulthood, and that services may mitigate some of this risk and present unique benefits for youth with disabilities. For example, the odds of employment are greater and the odds of receiving disability benefits are lower among those who receive academic supports (orFTE=1.3, orSSI/SSDI==0.7), post-secondary supports (orFTE=1.3, orSSI/SSDI=0.8), education financial assistance (orPTE=1.3, orSSI/SSDI=0.7), and career services (orPTE=1.3, orSSI/SSDI=0.8). These services should be prioritized for funding, especially education financial assistance as a lower proportion of youth with disabilities receive than their non-disabled peers.

RESUMO

We uncovered and reconstituted a concise biosynthetic pathway of the strained dipeptide (+)-azonazine A from marine-derived Aspergillus insulicola. Formation of the hexacyclic benzofuranoindoline ring system from cyclo-(l-Trp-N-methyl-l-Tyr) is catalyzed by a P450 enzyme through an oxidative cyclization. Supplementing the producing strain with various indole-substituted tryptophan derivatives resulted in the generation of a series of azonazine A analogs.

RESUMO

OBJECTIVE: Posttraumatic stress disorder (PTSD) is prevalent among people who have been incarcerated. Here, we examined whether screening positive for PTSD was associated with other indicators of poor health, acute healthcare utilization, and poverty among primary care patients upon release from incarceration. METHOD: We conducted a cross-sectional survey in a national network of primary care clinics serving people recently released from incarceration. Participants were 416 patients who completed the Primary Care PTSD screen (PC-PTSD) and other questions about mental and physical health, acute healthcare utilization, and economic status within 6 months of release. RESULTS: Screening positive for PTSD was associated with worse status across nearly all variables examined, including being more likely to report: poor/fair health (61.6% vs. 41.7%), current depressive symptoms (89.7% vs. 50.8%), lifetime depression diagnosis (63.3% vs. 35.3%), cannabis use since release (20.7% vs. 9.6%), homelessness (31.9% vs. 18.5%), having no cash on hand (56.3% vs. 39.0%) and severe food insecurity (29.3% vs. 18.2%; all ps < .01). Reporting recent suicidality (14.3% vs. 7.0%), alcohol use since release (30.2% vs. 20.0%), and emergency department utilization (20.4% vs. 12.2%) was also more likely (all ps ≤ .03). These trends were largely upheld when controlling for demographic characteristics and chronic physical health conditions using linear probability regression. CONCLUSIONS: Primary care patients recently released from incarceration have a need for wrap-around services that address health challenges and poverty. Patients with significant PTSD symptoms face even greater challenges. Identification and treatment of PTSD both during and after incarceration is warranted.

RESUMO

The COVID-19 pandemic created drastic changes for public education in the United States, including the role and responsibilities of educators. This study explores the self-reported psycho-social implications of COVID-19 among U.S. secondary teachers who are white, Black, Indigenous, and people of color. Using a national survey (n = 1,478) fielded between October 2020 and March 2021, we capture teachers' self-reported level of concern, life change, impact on thinking, and impact on teaching ability due to the COVID-19 pandemic. While teachers who are Black, Indigenous, and people of color report higher levels of concern and daily life change stemming from COVID-19, they report lower impacts on their teaching ability relative to their white peers. These findings are consistent with racial/ethnic disparities in COVID-19 case rates and mortality and highlight the resiliency of the U.S. secondary teachers who are Black, Indigenous, and people of color.

RESUMO

This study examined the effect of framing COVID-19 spread in correctional facilities as impacting imprisoned individuals or impacting correctional staff on public support for decarceration. I employed an experiment in the 2021 Empire State Poll (n = 765) in which participants were randomly assigned to a treatment condition, which highlighted information about the number of COVID-19 cases among imprisoned individuals, or a control condition, which highlighted correctional staff instead. Participants reported how supportive or unsupportive they are of releasing imprisoned individuals to curb the spread of COVID-19. Overall, 35% of New Yorkers supported decarceration. A higher percentage of respondents supported decarceration when the impact on correctional staff was highlighted (40%) relative to imprisoned individuals (31%). There was also higher support among non-Hispanic Black (54%) and Hispanic (51%) participants relative to non-Hispanic White (28%) participants. Within racial/ethnic groups support for decarceration was higher when the impact on correctional staff was highlighted among non-Hispanic Whites, Hispanics, and those of another race, but not among non-Hispanic Blacks where support for decarceration was higher when the impact on imprisoned individuals was highlighted. Inferential analysis using log binomial regression found that the association between treatment condition assignment and support for decarceration was not significant. Public health practitioners and policy makers should consider leveraging the higher support associated with concerns over the health and wellbeing of correction staff found among some racial/ethnic groups to fight the COVID-19 pandemic.

RESUMO

Sauromatum guttatum has been traditionally used in the treatment of snakebite and tumors in India, Pakistan, and China. However, it lacks detailed phytochemical composition like other members of the family Araceae. Therefore, the aim of the present study was to investigate the phytochemical composition of crude methanolic extract and subsequent fractions from S. guttatum tubers and to determine their enzyme inhibitory potentials. The phytochemical profile was studied through tandem high-resolution mass-based phytochemical analysis and Global Natural Product Social (GNPS) molecular networking. Similarly, crude extract and fractions were also investigated for enzyme inhibitory activity against urease and α-glucosidase. Twenty-six compounds were dereplicated belonging to flavone C-glycosides, flavone O-glycosides, phenolic acids, phenolic acid glycosides, and iridoid glycosides. The n-butanol fraction was particularly found rich in flavone di-C-glycosides including schaftoside, isoschaftoside, neoschaftoside, and vicenin-2. The n-butanol fraction exhibited the highest in vitro inhibition against urease and α-glucosidase with IC50 values of 113.7 µg/mL and 155.3 µg/mL, respectively. The results of enzyme inhibition potential were also supported by in silico molecular docking studies against the above-mentioned enzymes. This is the first report on the detailed phytochemical profile of S. guttatum tubers, and these results will contribute to the chemosystematic knowledge of the Araceae family. The results of this study also suggest that S. guttatum may find possible applications in the treatment of gastrointestinal disorders and diabetes.

RESUMO

Herein, we report on naturally derived microtubule stabilizers with activity against triple negative breast cancer (TNBC) cell lines, including paclitaxel, fijianolide B/laulimalide (3), fijianolide B di-acetate (4), and two new semisynthetic analogs of 3, which include fijianolide J (5) and fijianolide L (6). Similar to paclitaxel, compound 3 demonstrated classic microtubule stabilizing activity with potent (GI50 = 0.7-17 nM) antiproliferative efficacy among the five molecularly distinct TNBC cell lines. Alternatively, compounds 5 or 6, generated from oxidation of C-20 or C-15 and C-20 respectively, resulted in a unique profile with reduced potency (GI50 = 4-9 µM), but improved efficacy in some lines, suggesting a distinct mechanism of action. The C-15, C-20 di-acetate, and dioxo modifications on 4 and 6 resulted in compounds devoid of classic microtubule stabilizing activity in biochemical assays. While 4 also had no detectable effect on cellular microtubules, 6 promoted a reorganization of the cytoskeleton resulting in an accumulation of microtubules at the cell periphery. Compound 5, with a single C-20 oxo substitution, displayed a mixed phenotype, sharing properties of 3 and 6. These results demonstrate the importance of the C-15/C-20 chiral centers, which appear to be required for the potent microtubule stabilizing activity of this chemotype and that oxidation of these sites promotes unanticipated cytoskeletal alterations that are distinct from classic microtubule stabilization, likely through a distinct mechanism of action.

RESUMO

Forest fires produce malodorous phenols, bioaccumulated in grapes as odorless phenol glycosides (mono- to tri-), and produce unpleasant smoke tainted wines when these complexes are transformed by glycosidases in saliva. Metabolomic analyses were used to further understand smoke taint by quantitating marker phenolic diglycosides via UHPLC separations and MS/MS multiple reaction monitoring. A collection of grapes and wines provided data to forecast wine quality of grapes subjected to wildfire smoke infestations; the analytics used a panel of reference compounds (1-6). Overall, eight different Vitis vinifera varietals were examined from 2017-2021 vintages involving >218 distinct samples (wines and/or grapes) from 21 different American Viticulture Areas. Results acquired allowed correlation of phenolic diglycoside levels as a function of grape cultivar, varietal clones, and intensity of wildfire smoke. Baseline data were tabulated for nonsmoked samples (especially, Cabernet Sauvignon having a sum 1-6 of <6 µg/L) and then compared to those exposed to six other levels of smoke. Outcomes established that (1) analyzing paired samples (bottled wines versus smoke-exposed grapes) can provide diagnostic metabolomic data, (2) phenolic diglycosides are stable in wines aged for >2.5 years, and (3) major gaps exist in our current understanding of this pool of metabolites.

RESUMO

OBJECTIVE: This study examines how disability is associated with risk during the transition to adulthood for youth who age out of foster care and considers how experiences in the child welfare system contribute to these associations. BACKGROUND: The transition to adulthood is important for later socioeconomic standing, health, and wellbeing. Youth who age out of foster care with disabilities may require a high level of support during this transition yet may lack support. METHOD: This study employs linear probability models to estimate the association between disability and incarceration, homelessness, childbearing, and substance abuse between ages 17 and 21 using linked administrative data from the National Data Archive on Child Abuse and Neglect (N=5,221). RESULTS: Having a physical or sensory disability is associated with lower risk in the transition to adulthood. Alternatively, having an emotional or mental related disability is associated with increased risk of incarceration and homelessness, but the association with homelessness is accounted for by child welfare experiences. CONCLUSION: Due to the importance of foster care and child protective histories in explaining some risky outcomes for youth with emotional and mental disabilities, policy makers and practitioners should include those early stages of care when seeking it improve outcomes in the transition to adulthood for youth with disabilities who age out of foster care.

RESUMO

The phytochemical profile of Carissa opaca fruit extract and fractions was established through dereplication strategies employing LC-MS/MS and global natural product social molecular networking (GNPS). Crude extract and fractions were evaluated for their potential to inhibit α-glucosidase and urease in vitro. Flavonoid-O-glycosides, flavonoid-C-glycosides, flavonoids, proanthocyanidin B2, phenolics, and triterpenoids were annotated as the major classes of secondary metabolites present in the extract and fractions. α-Glucosidase inhibition was associated with n-butanol and ethyl acetate fractions comparable to acarbose (IC50 = 120.43 µg/mL) with IC50 values of 123.67 and 131.72 µg/mL, respectively. The ethyl acetate fraction showed good urease inhibition comparable with thiourea (IC50 = 103.71 µg/mL) with an IC50 value of 109.14 µg/mL. Molecular docking studies of compounds observed in the crude extract and bioactive fractions had significant binding scores, which supported results for enzyme inhibition in vitro. This study provided a detailed phytochemical profile of C. opaca fruit and its enzyme inhibition potential.

RESUMO

Sexual health is a critical indicator of wellbeing with consequences for population health. However, little is known about whether and how household member incarceration affects the sexual health behaviors of young adults. This study seeks to assess the association between household member incarceration and sexual health behaviors and provides an initial test of mechanisms. Drawing upon data from the NLSY97, this study estimates the association between household member incarceration and sexual health behaviors using linear probability models, and then re-estimates these associations using two alternative comparison groups; 1) youth who experienced other forms of stress, and 2) youth who experienced other forms of family absence. Results indicate that household incarceration is positively associated with a higher risk of reporting sexual intercourse with an intravenous drug user net of individual and family characteristics and is negatively associated with condom use net of individual but not family characteristics. The results also show that the associations between household member incarceration and sexual health behaviors may be attributable, at least in part, to the well documented stress associated with incarceration. Yet, the results provide little evidence that absence is a pathway linking household member incarceration to risky sexual health behaviors. It is possible that household member incarceration is linked to deleterious outcomes for youth through different mechanisms than parental incarceration given the differing roles of parents versus other adults in the home. Future research should explore the pathways linking household member incarceration to health risks for youth and consider household member incarceration as a unique family stressor.

RESUMO

BACKGROUND: COVID-19 has entered United States prison systems at alarming rates. Disparities in social and structural determinants of health disproportionately affect those experiencing incarceration, making them more vulnerable to COVID-19. Additionally, prisons are sites of congregate living, making it impossible to practice social distancing, and most prisons have relied only on incremental measures to reduce risk and spread of COVID-19. To more fully understand the impact that COVID-19 is having on incarcerated populations, it is critical to have systematic data on testing, test positivity, cases, and case fatality. Using data from the COVID Prison Project, we present data on 53 prison systems COVID-19 testing, test positivity, case, and case fatality by state and compare these data with each state's general population. We do this for the early stages of the pandemic, utilizing data through July 15, 2020. RESULTS: Many states are not reporting full information on COVID testing with some also not reporting on case fatality. Among those reporting data, there is a wide variation between testing, test positivity, and case rates within prison systems and as compared to the general population. However, when more tests are deployed more cases are identified with the majority of state prisons having higher case rates than their general population. CONCLUSIONS: These findings underscore the need for the implementation and study of COVID-19 mitigation and surveillance strategies to flatten the COVID-19 curve in prisons across the country. We call for future research to build on these data from the COVID Prison Project to protect the health of our nations' often forgotten residents.

RESUMO

Marine-derived bacteria are a prolific source of a wide range of structurally diverse natural products. This review, dedicated to Professor William Fenical, begins by showcasing many seminal discoveries made at the University of California San Diego from marine-derived actinomycetes. Discussed early on is the 20-year journey of discovery and advancement of the seminal actinomycetes natural product salinosporamide A into Phase III anticancer clinical trials. There are many fascinating parallels discussed that were gleaned from the comparative literature of marine sponge, tunicate, and bacteria-derived natural products. Identifying bacterial biosynthetic machinery housed in sponge and tunicate holobionts through both culture-independent and culture-dependent approaches is another important and expanding subject that is analyzed. Work reviewed herein also evaluates the hypotheses that many marine invertebrate-derived natural products are biosynthesised by associated or symbiotic bacteria. The insights and outcomes from metagenomic sequencing and synthetic biology to expand molecule discovery continue to provide exciting outcomes and they are predicted to be the source of the next generation of novel marine natural product chemical scaffolds.

RESUMO

Reinvestigation of mycothiazole (1) revealed picomolar potency (IC50 = 0.00016, 0.00027, 0.00035 µM) against pancreatic, (PANC-1), liver (HepG2), and colon (HCT-116) tumor cell lines. Reevaluation of 1 provided [α]D data indicating Vanuatu specimens of C. mycofijiensis contain the 8S enantiomer of 1 and not the 8R configuration previously reported. Semisynthesis provided 8-O-acetylmycothiazole (2), 8-oxomycothiazole (8), mycothiazole nitrosobenzene derivatives (MND1, MND2: 9a, 9b), and MND3 (10) with IC50 = 0.00129, >1.0, >1.0, >1.0, >1.0 µM, respectively, against PANC-1 cell lines. These results highlight the significance of the penta-2,4-dien-1-ol residue as a key structural feature of 1 required for its cytotoxicty against tumor cell lines.

RESUMO

This study began with the goal of identifying additional constituents from Zyzzya fuliginosa extracts obtained from an Indo-Pacific sponge (coll. no. 06132). The previous work identified several red and green pyrroloiminiquinones (aka pyrrolo[4,3,2-de]quinolines), and this reinvestigation provided two additional analogues, a blue compound named zyzzamine A (1) and a green compound named zyzzamine B (2). The relatively low ratio of H/[sum(CNO)] = 0.71 or 0.76 of this pair greatly complicated the final steps of compound characterization and required the use of five 2D NMR strategies and MS2 data sets.

RESUMO

The author uses strategic comparison regression and the Longitudinal Study of Adolescent to Adult Health (n = 11,767) to explore the effect of parental incarceration on academic and nonacademic outcomes in high school. This method compares youth whose parents were incarcerated before the outcomes are measured with those whose parents will be incarcerated after. The author examines most recent grades and a range of nonacademic outcomes, such as truancy, involvement in school activities, and suspension. Results indicate that the associations between parental incarceration and grades are largely accounted for by selection, but associations between parental incarceration and nonacademic processes persist. Maternal incarceration holds particular importance for behavioral outcomes (fighting and truancy), and paternal incarceration holds particular importance for behavioral, connectedness, and disciplinary outcomes. Researchers examining the intergenerational consequences of incarceration should examine school contexts beyond the classroom and explore the pathways through which this disadvantage occurs.

RESUMO

Purpose: To document the health-related experiences and needs of jail detainees who self-identified as transgender women. Methods: Semistructured interviews with 10 transgender women of color were conducted in a county jail in a mid-sized southern city between 2015 and 2016. Interviews were recorded and transcribed, and later analyzed using a general inductive approach. Results: Participants experienced high levels of abuse and harassment, solitary confinement, mental health issues, and lack of access to hormone treatment. Participants described discrimination (both by other inmates-particularly while in special housing units-and correctional officers); harsh correctional conditions, which exacerbated mental health issues; and a marked lack of access to healthcare, including hormone treatments. Conclusion: Policy changes are needed to address housing and placement issues, and to increase access to healthcare for transgender women jail detainees. Training is needed for jail staff and medical care professionals in correctional settings to better understand the unique needs and experiences of transgender people.

RESUMO

The United States (US) is in the midst of an epidemic of opioid use; however, overdose mortality disproportionately affects certain subgroups. For example, more than half of state prisoners and approximately two-thirds of county jail detainees report issues with substance use. Overdose is one of the leading causes of mortality among individuals released from correctional settings. Even though the criminal justice (CJ) system interacts with a disproportionately high number of individuals at risk of opioid use and overdose, few CJ agencies screen for opioid use disorder (OUD). Even less provide access to medication assisted treatment (e.g. methadone, buprenorphine, and depot naltrexone), which is one of the most effective tools to combat addiction and lower overdose risk. However, there is an opportunity to implement programs across the CJ continuum in collaboration with law enforcement, courts, correctional facilities, community service providers, and probation and parole. In the current paper, we introduce the concept of a "CJ Continuum of Care for Opioid Users at Risk of Overdose", grounded by the Sequential Intercept Model. We present each step on the CJ Continuum and include a general overview and highlight opportunities for: 1) screening for OUD and overdose risk, 2) treatment and/or diversion, and 3) overdose prevention and naloxone provision.
