ABSTRACT

Endocrine disrupting chemicals (EDCs) such as bisphenol S (BPS) are xenobiotic compounds that can disrupt endocrine signaling following exposure due to steric similarities to endogenous hormones within the body. EDCs have been shown to induce disruptions in normal epigenetic programming (epimutations) that accompany dysregulation of normal gene expression patterns that appear to predispose disease states. Most interestingly, the prevalence of epimutations following exposure to many different EDCs often persists over multiple subsequent generations, even with no further exposure to the causative EDC. Many previous studies have described both the direct and prolonged effects of EDC exposure in animal models, but many questions remain about molecular mechanisms by which EDCs initially induce epimutations or contribute to the propagation of EDC-induced epimutations either within the exposed generation or to subsequent generations. Additional questions remain regarding the extent to which there may be differences in cell-type specific susceptibilities to various EDCs, and whether this susceptibility is correlative with expression of relevant hormone receptors and/or the location of relevant hormone response elements (HREs) in the genome. To address these questions, we exposed cultured mouse pluripotent (induced pluripotent stem [iPS]), somatic (Sertoli and granulosa), and germ (primordial germ cell like [PGCLC]) cells to BPS and measured changes in DNA methylation levels at the epigenomic level and gene expression at the transcriptomic level. We found that there was indeed a difference in cell-type specific susceptibility to EDC-induced epimutagenesis and that this susceptibility correlated with differential expression of relevant hormone receptors and, in many cases, tended to generate epimutations near relevant HREs within the genome. Additionally, however, we also found that BPS can induce epimutations in a cell type that does not express relevant receptors and in genomic regions that do not contain relevant HREs, suggesting that both canonical and non-canonical signaling mechanisms can be disrupted by BPS exposure. Most interestingly, we found that when iPS cells were exposed to BPS and then induced to differentiate into PGCLCs, the prevalence of epimutations and differentially expressed genes (DEGs) initially induced in the iPSCs was largely retained in the resulting PGCLCs, however, >90% of the specific epimutations and DEGs were not conserved but were rather replaced by novel epimutations and DEGs following the iPSC to PGCLC transition. These results are consistent with a unique concept that many EDC-induced epimutations may normally be corrected by germline and/or embryonic epigenetic reprogramming but that due to disruption of the underlying chromatin architecture induced by the EDC exposure, many novel epimutations may emerge during the reprogramming process as well. Thus, it appears that following exposure to a disruptive agent such as an EDC, a prevalence of epimutations may transcend epigenetic reprogramming even though most individual epimutations are not conserved during this process.

ABSTRACT

PURPOSE: Feedback and evaluation from peers is fundamental to trainees' professional development but may be uncomfortable to provide non-anonymously. We aimed to understand resident perception of anonymous and open written evaluation systems and to analyze evaluations in each of these systems. MATERIALS AND METHOD: We compared two years of intern peer evaluations at a large United States-based pediatric residency program - the 2018-2019 and 2019-2020 years during which intern peer evaluations were anonymous and open, respectively. We electronically surveyed interns about their perceptions of peer evaluations and analyzed four aspects of the evaluations themselves: (1) orientation, (2) caliber, (3) Likert-scale, and (4) word count. RESULTS: 40 (78%) and 38 (75%) interns participated in the survey in the anonymous and open years, respectively. Respondents reported being more likely to avoid writing constructive comments in the open year. There were more high caliber comments in the open year. Likert-scale ratings of peers were lower in the open year. Word count was longer in the open year. CONCLUSIONS: While interns expressed more discomfort evaluating peers in an open evaluation system, they wrote longer and more high caliber comments in an open system than in an anonymous system. Residency programs should consider professional development in writing peer evaluation.


Residents are uncomfortable writing constructive comments in peer evaluations, particularly in open formats.Residents write similar numbers of constructive comments whether the evaluation is delivered anonymously or in an open format.Residents write more high caliber comments when evaluations are delivered in an open format than when delivered anonymously.Residents write longer comments when evaluations are in an open format.Program leaders should weigh the increased number of high caliber peer evaluations in an open system with resident preference for an anonymous system when designing their peer evaluation systems.

ABSTRACT

Purpose: Noninvasive cell-type-specific manipulation of neural signaling is critical in basic neuroscience research and in developing therapies for neurological disorders. Magnetic nanotechnologies have emerged as non-invasive neuromodulation approaches with high spatiotemporal control. We recently developed a wireless force-induced neurostimulation platform utilizing micro-sized magnetic discs (MDs) and low-intensity alternating magnetic fields (AMFs). When targeted to the cell membrane, MDs AMFs-triggered mechanoactuation enhances specific cell membrane receptors resulting in cell depolarization. Although promising, it is critical to understand the role of mechanical forces in magnetomechanical neuromodulation and their transduction to molecular signals for its optimization and future translation. Methods: MDs are fabricated using top-down lithography techniques, functionalized with polymers and antibodies, and characterized for their physical properties. Primary cortical neurons co-cultured with MDs and transmembrane protein chemical inhibitors are subjected to 20 s pulses of weak AMFs (18 mT, 6 Hz). Calcium cell activity is recorded during AMFs stimulation. Results: Neuronal activity in primary rat cortical neurons is evoked by the AMFs-triggered actuation of targeted MDs. Ion channel chemical inhibition suggests that magnetomechanical neuromodulation results from MDs actuation on Piezo1 and TRPC1 mechanosensitive ion channels. The actuation mechanisms depend on MDs size, with cell membrane stretch and stress caused by the MDs torque being the most dominant. Conclusions: Magnetomechanical neuromodulation represents a tremendous potential since it fulfills the requirements of negligible heating (ΔT < 0.1 °C) and weak AMFs (< 100 Hz), which are limiting factors in the development of therapies and the design of clinical equipment.

ABSTRACT

Nowadays there are multiple types of contraceptive methods, from reversible to permanent, for those choosing to delay pregnancy. Misconceptions about contraception and infertility are a key factor for discontinuation or the uptake of family planning methods. Regaining fertility (the ability to conceive) after contraceptive discontinuation is therefore pivotal. Technical studies to date have evaluated return to fertility by assessing pregnancy as an outcome, with variable results, or return to ovulation as a surrogate measure by assessing hormone levels (such as progesterone, LH, FSH) with or without transvaginal ultrasound. In general, relying on time to pregnancy as an indicator of return to fertility following contraceptive method discontinuation can be problematic due to variable factors independent of contraceptive effects on fertility, hormone clearance, and fertility recovery. Since the ability to conceive after contraceptive method discontinuation is a critical factor influencing product uptake, it is important to have robust biomarkers that easily and accurately predict the timing of fertility return following contraception and isolate that recovery from extrinsic and circumstantial factors. The main aim of this review is to summarize the current approaches, existing knowledge, and gaps in methods of evaluating return-to-fertility as well as to provide insights into the potential of new biomarkers to more accurately predict fertility restoration after contraceptive discontinuation. Biomarker candidates proposed in this document include those associated with folliculogenesis, cumulus cell expansion, follicular rupture and ovulation, and endometrial transport and receptivity which have been selected and scored on predefined criteria meant to evaluate their probable viability for advancement. The review also describes limitations, regulatory requirements, and a potential path to clinically testing these selected biomarkers. It is important to understand fertility restoration after contraceptive method discontinuation to provide users and health providers with accurate evidence-based information. Predictive biomarkers, if easy and low-cost, have the potential to enable robust evaluation of RTF, and provide potential users the information they desire when selecting a contraceptive method. This could lead to expanded uptake and continuation of modern contraception and inform the development of new contraceptive methods to widen user's family planning choices.

ABSTRACT

Extremely low-frequency electromagnetic stimulation (ELF-EMS) was demonstrated to be significantly beneficial in rodent models of permanent stroke. The mechanism involved enhanced cerebrovascular perfusion and endothelial cell nitric oxide production. However, the possible effect on the neuroinflammatory response and its efficacy in reperfusion stroke models remains unclear. To evaluate ELF-EMS effectiveness and possible immunomodulatory response, we studied neurological outcome, behavior, neuronal survival, and glial reactivity in a rodent model of global transient stroke treated with 13.5 mT/60 Hz. Next, we studied microglial cells migration and, in organotypic hippocampal brain slices, we assessed neuronal survival and microglia reactivity. ELF-EMS improved the neurological score and behavior in the ischemia-reperfusion model. It also improved neuronal survival and decreased glia reactivity in the hippocampus, with microglia showing the first signs of treatment effect. In vitro ELF-EMS decreased (Lipopolysaccharide) LPS and ATP-induced microglia migration in both scratch and transwell assay. Additionally, in hippocampal brain slices, reduced microglial reactivity, improved neuronal survival, and modulation of inflammation-related markers was observed. Our study is the first to show that an EMF treatment has a direct impact on microglial migration. Furthermore, ELF-EMS has beneficial effects in an ischemia/reperfusion model, which indicates that this treatment has clinical potential as a new treatment against ischemic stroke.

ABSTRACT

The exposure of humans to Cd exerts adverse human health effects at low chronic exposure doses, but the underlying biomolecular mechanisms are incompletely understood. To gain insight into the toxicologically relevant chemistry of Cd2+ in the bloodstream, we employed an anion-exchange HPLC coupled to a flame atomic absorption spectrometer (FAAS) using a mobile phase of 100 mM NaCl with 5 mM Tris-buffer (pH 7.4) to resemble protein-free blood plasma. The injection of Cd2+ onto this HPLC-FAAS system was associated with the elution of a Cd peak that corresponded to [CdCl3]-/[CdCl4]2- complexes. The addition of 0.1-10 mM L-cysteine (Cys) to the mobile phase significantly affected the retention behavior of Cd2+, which was rationalized by the on-column formation of mixed CdCysxCly complexes. From a toxicological point of view, the results obtained with 0.1 and 0.2 mM Cys were the most relevant because they resembled plasma concentrations. The corresponding Cd-containing (~30 µM) fractions were analyzed by X-ray absorption spectroscopy and revealed an increased sulfur coordination to Cd2+ when the Cys concentration was increased from 0.1 to 0.2 mM. The putative formation of these toxicologically relevant Cd species in blood plasma was implicated in the Cd uptake into target organs and underscores the notion that a better understanding of the metabolism of Cd in the bloodstream is critical to causally link human exposure with organ-based toxicological effects.

ABSTRACT

HIV-related stigma has been associated with poor mental health among people with HIV (PWH). Social support is a potentially modifiable factor that may buffer negative mental health sequelae of HIV-related stigma. Little is known about the extent to which the modifying effect of social support differs across mental health disorders. Interviews were conducted with 426 PWH in Cameroon. Log binomial regression analyses were used to estimate the association between high anticipated HIV-related stigma and low social support from family or friends and symptoms of depression, anxiety, post-traumatic stress disorder (PTSD), and harmful alcohol use, separately. Anticipated HIV-related stigma was commonly endorsed with ∼80% endorsing at least 1 of 12 stigma-related concerns. In multivariable analyses, high anticipated HIV-related stigma was associated with greater prevalence of symptoms of depression {adjusted prevalence ratio (aPR) 1.6 [95% confidence interval (CI) 1.1-2.2]} and anxiety [aPR 2.0 (95% CI 1.4-2.9)]. Low social support was associated with greater prevalence of symptoms of depression [aPR 1.5 (95% CI 1.1-2.2)], anxiety [aPR 1.7 (95% CI 1.2-2.5)], and PTSD [aPR 1.6 (95% CI 1.0-2.4)]. However, social support did not meaningfully modify the relationship between HIV-related stigma and symptoms of any mental health disorders explored. Anticipated HIV-related stigma was commonly reported among this group of PWH initiating HIV care in Cameroon. Social concerns related to gossip or losing friends were of the greatest concern. Interventions focused on reducing stigma and strengthening support systems may be particularly beneficial and have the potential to improve the mental health of PWH in Cameroon.

ABSTRACT

Little is known about the coping strategies used among people with HIV (PWH), especially in sub-Saharan Africa, and the extent to which adaptive or maladaptive coping strategies are associated with symptoms of mental health disorders. We interviewed 426 PWH initiating HIV care in Cameroon and reported the prevalence of adaptive and maladaptive coping strategies, overall and by presence of symptoms of depression, anxiety, and PTSD. Log binominal regression was used to estimate the association between each type of coping strategy (adaptive or maladaptive) and symptoms of each mental health disorder, separately. Adaptive and maladaptive coping strategies were commonly reported among PWH enrolling in HIV care in Cameroon. Across all mental health disorders assessed, greater maladaptive coping was associated with higher prevalence of depression, anxiety, and PTSD. Adaptive coping was not associated with symptoms of any of the mental health disorders assessed in bivariate or multivariable models. Our study found that PWH endorsed a range of concurrent adaptive and maladaptive coping strategies. Future efforts should explore the extent to which coping strategies change throughout the HIV care continuum. Interventions to reduce maladaptive coping have the potential to improve the mental health of PWH in Cameroon.

ABSTRACT

Minimally invasive manipulation of cell signaling is critical in basic neuroscience research and in developing therapies for neurological disorders. Here, we describe a wireless chemomagnetic neuromodulation platform for the on-demand control of primary striatal neurons that relies on nanoscale heating events. Iron oxide magnetic nanoparticles (MNPs) are functionally coated with thermoresponsive poly (oligo (ethylene glycol) methyl ether methacrylate) (POEGMA) brushes loaded with dopamine. Dopamine loaded MNPs-POEGMA are co-cultured with primary striatal neurons. When alternating magnetinec fields (AMF) are applied, MNPs undergo hysteresis power loss and dissipate heat. The local heat produced by MNPs initiates a thermodynamic phase transition on POEGMA brushes resulting in polymer collapse and dopamine release. AMF-triggered dopamine release enhances the response of dopamine ion channels expressed on the cell membranes enhancing the activity of ~50% of striatal neurons subjected to the treatment. Chemomagnetic actuation on dopamine receptors is confirmed by blocking D1 and D2 receptors. The reversible thermodynamic phase transition of POEGMA brushes allow the on-demand release of dopamine in multiple microdoses. AMF-triggered dopamine release from MNPs-POEGMA causes no cell cytotoxicity nor promotes cell ROS production. This research represents a fundamental step forward for the chemomagnetic control of neural activity using hybrid magnetic nanomaterials with tailored physical properties.

ABSTRACT

Background: Contraceptive-induced menstrual changes (CIMCs) can affect family planning (FP) users' lives in both positive and negative ways, resulting in both opportunities and consequences. Despite this, and despite the important links between FP and menstrual health (MH), neither field adequately addresses CIMCs, including in research, product development, policies, and programs globally. Methods: In November 2020, a convening of both MH and FP experts reviewed the existing evidence on CIMCs and identified significant gaps in key areas. Results: These gaps led to the establishment of a CIMC Task Force in April 2021 and the development of the Global Research and Learning Agenda: Building Evidence on Contraceptive-Induced Menstrual Changes in Research, Product Development, Policies, and Programs Globally (the CIMC RLA) , which includes four research agendas for (1) measurement, (2) contraceptive research and development (R&D) and biomedical research, (3) social-behavioral and user preferences research, and (4) programmatic research. Conclusions: Guided by the CIMC RLA, researchers, product developers, health care providers, program implementers, advocates, policymakers, and funders are urged to conduct research and implement strategies to address the beneficial and negative effects of CIMCs and support the integration of FP and MH. CIMCs need to be addressed to improve the health and well-being of women, girls, and other people who menstruate and use contraceptives globally.

ABSTRACT

PURPOSE: Clinical fellows, those training to become subspecialists in a program certified by the Accreditation Council for Graduate Medical Education, supervise residents on inpatient subspecialty rotations. Unlike for supervising residents or for faculty, there is a paucity of literature describing fellows' supervision of residents. The aim of this study was to understand residents' and fellows' perception of successful supervision of residents by fellows on inpatient subspecialty rotations to inform the development of curricula to support fellows as supervisors. METHOD: Using grounded theory methodology, the authors held focus groups in May 2020 of pediatric residents and pediatric subspecialty fellows at Boston Children's Hospital, Boston, Massachusetts. Focus groups were conducted until thematic saturation was achieved. Deidentified transcripts were independently coded by 2 authors. The author team consolidated the codes into themes and developed an interpretive model for fellows' successful supervision of residents. Key results were confirmed via member checking. RESULTS: The authors conducted 4 resident focus groups, composed of 16 pediatric residents, and 4 fellow focus groups, composed of 13 pediatric subspecialty fellows. Participants perceived that fellows who provided successful resident supervision advanced residents' professional growth and supported residents' development along 5 "bridges": (1) generalist to subspecialist, (2) trainee to autonomous practitioner, (3) individual to member of the interprofessional team, (4) emerging physician to patient-facing care provider, and (5) newcomer to engaged clinical learner. Fellows can further residents' growth in these areas by demonstrating approachability, empathy, appreciation, and kindness. CONCLUSIONS: As newcomers on inpatient subspecialty rotations, residents engage in legitimate peripheral participation. Fellows who are successful supervisors move residents toward full participation in their profession via the bridge model. The fellow-resident dynamic carries advantages of near-peer learning. Fellows can harness their role, subspecialty knowledge, and familiarity with the training environment to enhance resident supervision.

ABSTRACT

Noninvasive manipulation of cell signaling is critical in basic neuroscience research and in developing therapies for neurological disorders and psychiatric conditions. Here, the wireless force-induced stimulation of primary neuronal circuits through mechanotransduction mediated by magnetic microdiscs (MMDs) under applied low-intensity and low-frequency alternating magnetic fields (AMFs), is described. MMDs are fabricated by top-down lithography techniques that allow for cost-effective mass production of biocompatible MMDs with high saturation and zero magnetic magnetic moment at remanence. MMDs are utilized as transducers of AMFs into mechanical forces. When MMDs are exposed to primary rat neuronal circuits, their magneto-mechanical actuation triggers the response of specific mechanosensitive ion channels expressed on the cell membranes activating ≈50% of hippocampal and ≈90% of cortical neurons subjected to the treatment. Mechanotransduction is confirmed by the inhibition of mechanosensitive transmembrane channels with Gd3+ . Mechanotransduction mediated by MMDs cause no cytotoxic effect to neuronal cultures. This technology fulfills the requirements of cell-type specificity and weak magnetic fields, two limiting factors in the development of noninvasive neuromodulation therapies and clinical equipment design. Moreover, high efficiency and long-lasting stimulations are successfully achieved. This research represents a fundamental step forward for magneto-mechanical control of neural activity using disc-shaped micromaterials with tailored magnetic properties.

ABSTRACT

Los accidentes cerebrovasculares se han mantenido, a nivel mundial, como la tercera causa de muerte y la primera de discapacidad. Para disminuir la incidencia de casos de isquemia o hemorragia cerebral, así como sus consecuencias, se deben poseer los conocimientos sobre dichas entidades clínicas, los factores de riesgo asociados y las alternativas preventivas y terapéuticas como estrategias neuroprotectoras. Muchas de las intervenciones médicas realizadas hasta la fecha en modelos animales han resultado insatisfactorias en la fase clínica. Por ello, se realizó una revisión de las publicaciones más recientes donde se abordan los modelos experimentales para la isquemia cerebral más utilizados en las evaluaciones de las terapias neuroprotectoras, y se pudo concluir que si se analizan los protocolos empleados en la fase preclínica podrán optimizarse las investigaciones para lograr resultados más acertados en este campo.


The strokes have been considered, worldwide, as the third cause of death and the first cause of disability. To diminish the incidence of ischemia cases or cerebral hemorrhage, as well as their consequences, one should have the knowledge on this clinical entities, the associated risk factors and preventive and therapeutic alternatives as neuroprotector strategies. Many of the medical interventions carried out so far in animal models have been unsatisfactory in the clinical phase. Reason why, a review of the most recent publications was carried out, where the most used experimental models for the cerebral ischemia in the evaluations of the neuroprotector therapies are approached, and it was concluded that if protocols used in the preclinic phase are analyzed, the investigations could be optimize to achieve more relevant results in this field.

ABSTRACT

Cerebral stroke is a leading cause of death and adult-acquired disability worldwide. To this date, treatment options are limited; hence, the search for new therapeutic approaches continues. Electromagnetic fields (EMFs) affect a wide variety of biological processes and accumulating evidence shows their potential as a treatment for ischemic stroke. Based on their characteristics, they can be divided into stationary, pulsed, and sinusoidal EMF. The aim of this review is to provide an extensive literature overview ranging from in vitro to even clinical studies within the field of ischemic stroke of all EMF types. A thorough comparison between EMF types and their effects is provided, as well as an overview of the signal pathways activated in cell types relevant for ischemic stroke such as neurons, microglia, astrocytes, and endothelial cells. We also discuss which steps have to be taken to improve their therapeutic efficacy in the frame of the clinical translation of this promising therapy.

ABSTRACT

OBJECTIVES: A large portion of residency education occurs in inpatient teaching services without widely accepted consensus regarding the essential components that constitute a teaching service. We sought to generate consensus around this topic, with the goal of developing criteria programs that can be used when creating, redesigning, or evaluating teaching services. METHODS: A list of potential components of teaching services was developed from a literature search, interviews, and focus groups. Eighteen pediatric medical education experts participated in a modified Delphi method, responding to a series of surveys rating the importance of the proposed components. Each iterative survey was amended on the basis of the results of the previous survey. A final survey evaluating the (1) effort and (2) impact of implementing components that had reached consensus as recommended was distributed. RESULTS: Each survey had 100% panelist response. Five survey rounds were conducted. Fourteen attending physician characteristics and 7 system characteristics reached consensus as essential components of a teaching service. An additional 25 items reached consensus as recommended. When evaluating the effort and impact of these items, the implementation of attending characteristics was perceived as requiring less effort than system characteristics but as having similar impact. CONCLUSIONS: Consensus on the essential and recommended components of a resident teaching service was achieved by using the modified Delphi method. Although the items that reached consensus as essential are similar to those proposed by the Accreditation Council for Graduate Medical Education, those that reached consensus as recommended are less commonly discussed and should be strongly considered by institutions.

ABSTRACT

​The advance in the human genetic field has permitted to identify small chromosome alterations and associate them to a specific phenotype. However, there are many mutations that have not yet been described in the literature. We describe the clinical case of a term newborn with appropriate weight to its gestational age, without perinatal background of interest that, at birth, presented: macrocephaly, hypertelorism, low-set ears, prominent forehead, micrognathia, camptodactyly, bilateral cryptorchidism, inspiratory stridor with the cry, multifocal systolic murmur, wide anterior fontanel and hypotonia of mixed characteristics and in whom a deletion of the 1q44 cytoband and a pathogenic duplication in the 9q32q34.3 cytoband were detected. We perform a review of the literature.

ABSTRACT

PURPOSE: Thoracic-cancer (TC) patients have an extensive toll taken in terms of health-related quality of life (HRQL). Integrative Oncology (IO) is recognized as a valid complement to any Standard-Therapy treatment to improve outcomes in TC patients. The objective of this pilot-study was to evaluate the effect of adding IO (acupuncture, Cognitive-Behavior Therapy and mindfulness) in terms of depression, anxiety and HRQL. METHODS: TC patients who attended the Thoracic Oncology-Unit from July to September 2018 were invited to participate. A total of 16 patients were included in the study, 8 patients were required to attend 5 weekly sessions of IO and 8 patients were invited as controls. Anxiety, depression and HRQL were measured at baseline and after completing 5 sessions of IO or 5 weeks, using the HADS scale and the QLQ-C30 scale. RESULTS: A total of 8 patients in the IO group attended the 5 sessions and 8 patients were followed as controls. Compliance with the therapies was high, none of the patients dropped out from the study. A tendency for improvement in anxiety, fatigue, pain and dyspnea was observed in patients attending IO, though not statistically significant likely due to sample size. CONCLUSIONS: IO therapies are well accepted among TC patients. Larger studies are necessary with robust sample sizes to improve conclusions regarding outcome improvements.

ABSTRACT

OBJECTIVES: To study the incidence, risk factors, clinical course, and outcome of ARDS in children with HMP and RSV. WORKING HYPOTHESIS: We hypothesized that ARDS in children with HMP was similar in incidence, risk factors, clinical course, and outcomes to ARDS in children with RSV. STUDY DESIGN: Retrospective, observational study over 2 years. PATIENT-SUBJECT SELECTION: Patients included were <18 years old with HMP or RSV detected from nasopharyngeal specimens by commercial reverse transcriptase polymerase chain reaction assay admitted to a study site. METHODOLOGY: We described the incidence of ARDS within 1 week following the detection of HMP or RSV using recently developed Pediatric ARDS (PARDS) criteria. We also assessed risk factors, clinical course, and outcomes of children in the PICU with HMP or RSV and PARDS or non-PARDS. RESULTS: We identified 57 patients with HMP and 161 patients with RSV: the proportions of patients with either virus who developed PARDS (HMP: 23%, RSV: 20%) and severe PARDS (HMP: 9%, RSV: 7%) were similar, as were the proportions of patients with acute (or acute-on-chronic) respiratory failure who developed PARDS (HMP: 41%, RSV: 31%). In a logistic regression model, risk factors associated with PARDS included neurologic comorbidity and PIM 3 probability of mortality, but not virus type. The risk factors, clinical course, and outcomes were similar for patients with PARDS associated with HMP and RSV. CONCLUSIONS: About 1/3 of children with HMP or RSV and acute (or acute-on-chronic) respiratory failure developed PARDS. Children with either virus and a neurologic comorbidity or an increased PIM 3 probability of mortality were at increased risk for PARDS.

ABSTRACT

BACKGROUND: We apply Intersectional Theory to examine how compounded disadvantage affects the odds of women having a cesarean in U.S.-Mexico border hospitals and in non-border hospitals. We define U.S. Latinas with compounded disadvantage as those who have neither a college education nor private health insurance. RESULTS: Analyzing quantitative and qualitative data from Childbirth Connection's Listening to Mothers III Survey, we find that, consistent with the notion of the Latinx Health Paradox, compounded disadvantage serves as a protective buffer and decreases the odds of cesarean among women in non-border hospitals. However, the Latinx Health Paradox is absent on the border. CONCLUSION: Our data show that women with compounded disadvantage who give birth on the border have significantly higher odds of a cesarean compared to women without such disadvantage. Further, women with compounded disadvantage who give birth in border hospitals report receiving insufficient prenatal, pregnancy, and postpartum information, providing a direction for future research to explain the border disparity in cesareans.
