RESUMO

BACKGROUND: The interstage period after discharge from stage 1 palliation carries high morbidity and mortality. The impact of social determinants of health on interstage outcomes is not well characterized. We assessed the relationship between childhood opportunity and acute interstage outcomes. METHODS: Infants discharged home after stage 1 palliation in the National Pediatric Quality Improvement Collaborative Phase II registry (2016-2022) were retrospectively reviewed. Zip code-level Childhood Opportunity Index (COI), a composite metric of 29 indicators across education, health and environment, and socioeconomic domains, was used to classify patients into 5 COI levels. Acute interstage outcomes included death or transplant listing, unplanned readmission, intensive care unit admission, unplanned catheterization, and reoperation. The association between COI level and acute interstage outcomes was assessed using logistic regression with sequential adjustment for potential confounders. RESULTS: The analysis cohort included 1837 patients from 69 centers. Birth weight (P<0.001) and proximity to a surgical center at birth (P=0.02) increased with COI level. Stage 1 length of stay decreased (P=0.001), and exclusive oral feeding rate at discharge increased (P<0.001), with higher COI level. More than 98% of patients in all COI levels were enrolled in home monitoring. Death or transplant listing occurred in 101 (5%) patients with unplanned readmission in 987 (53%), intensive care unit admission in 448 (24%), catheterization in 345 (19%), and reoperation in 83 (5%). There was no difference in the incidence or time to occurrence of any acute interstage outcome among COI levels in unadjusted or adjusted analysis. There was no interaction between race and ethnicity and childhood opportunity in acute interstage outcomes. CONCLUSIONS: Zip code COI level is associated with differences in preoperative risk factors and stage 1 palliation hospitalization characteristics. Acute interstage outcomes, although common across the spectrum of childhood opportunity, are not associated with COI level in an era of highly prevalent home monitoring programs. The role of home monitoring in mitigating disparities during the interstage period merits further investigation.

RESUMO

Antibiotic use in early life disrupts microbial colonization and increases the risk of developing allergies and asthma. We report that mice given antibiotics in early life (EL-Abx), but not in adulthood, were more susceptible to house dust mite (HDM)-induced allergic airway inflammation. This susceptibility was maintained even after normalization of the gut microbiome. EL-Abx decreased systemic levels of indole-3-propionic acid (IPA), which induced long-term changes to cellular stress, metabolism, and mitochondrial respiration in the lung epithelium. IPA reduced mitochondrial respiration and superoxide production and altered chemokine and cytokine production. Consequently, early-life IPA supplementation protected EL-Abx mice against exacerbated HDM-induced allergic airway inflammation in adulthood. These results reveal a mechanism through which EL-Abx can predispose the lung to allergic airway inflammation and highlight a possible preventative approach to mitigate the detrimental consequences of EL-Abx.

RESUMO

This paper discusses some of the main criteria used to define priorities for technological and industrial development by the Brazilian Ministry of Health regarding the Partnerships for Productive Development (PDP) Program. In order to focus on the question of how to define priorities for technological development, the methodologies developed by the WHO and the EMA for that purpose are presented. WHO's and Brazilian findings on main causes of burden of disease are briefly compared. WHO's selected findings on major therapeutical gaps and technological development priorities are also compared to priorities selected and supported by the PDP program since its inception. A divorce between medicines prioritized and supported by the PDP program and the main causes of the Brazilian burden of disease was observed. Also, the incremental cost-effectiveness ratios of several medications supported by the program were preliminarily estimated. The resulting ratios were about thirty times higher than the opportunity cost estimated for Brazil. Findings of the above comparisons and cost-effectiveness exercise indicate that inadequate choices were made by the PDP program in the way to a progressive and equanimous universal health access in Brazil, anticipating a low impact on the Brazilian total burden of disease as well as a low effectiveness, efficiency and equity of the program regarding the health of the Brazilian population as a whole.


Estudos brasileiros que analisaram as Parcerias para o Desenvolvimento Produtivo (PDP) apontam limitações do desenho e da implementação das PDPs de medicamentos vis à vis os objetivos de saúde do SUS. Este artigo discute a definição de prioridades para o desenvolvimento tecnológico e industrial do complexo da saúde (CEIS), com foco na universalidade e na equidade em saúde, tendo por objeto o programa de Parcerias para o Desenvolvimento Produtivo (PDP) do Ministério da Saúde, programa de gastos anuais multibilionários, iniciado em 2009. Para aprofundar a questão do processo utilizado para definir prioridades de desenvolvimento tecnológico, o presente trabalho revê as metodologias utilizadas pela OMSepela European Medicines Agency (EMA) para esse propósito. As prioridades de saúde definidas pela OMS, partindo principalmente do critério carga de doença, e as correspondentes lacunas terapêuticas selecionadas para desenvolvimento tecnológico, com base sobretudo em evidências de monitoramento do horizonte e de avaliação tecnológica, são resumidamente apresentadas. A seguir, foram comparados os achados do relatório da OMS_ as prioridades de saúde selecionadas e as prioridades tecnológicas resultantes_ com os achados sobre carga de doença no Brasil e as prioridades selecionadas e apoiadas pelas PDPs. Observou-se um divórcio entre as prioridades medicamentosas apoiadas pelas PDPs e as principais causas de carga de doença no país. Abordamos ainda, nesse artigo, o papel da análise de custo-efetividade e do custo de oportunidade na discussão das escolhas do programa PDP. O exemplo trabalhado indica que o custo de oportunidade de várias tecnologias apoiadas pelas PDPs vigentes é dezenas de vezes superior ao limiar de custo-efetividade estimado para o Brasil. O divórcio entre as prioridades apoiadas pelas PDPs e as principais causas de carga de doença no país e o limiar de custo-efetividade assumido pelo programa PDP indicam escolhas insatisfatórias na busca para alcançar, de forma progressiva e equânime, o acesso universal à atenção de saúde em nosso país, no SUS. Essas escolhas devem resultar em uma baixa efetividade, baixa eficiência e baixa equidade do programa do ponto de vista da saúde da população brasileira como um todo.

RESUMO

This paper studies multigenerational health transmission mechanisms in Australian panel data. Using inequality-of-opportunity (IOP) models, we demonstrate that grandparental socioeconomic status (SES) is an important determinant of personal health, even after controlling for health and SES at the parental level. Our findings hold over a range of health/biomarkers of individuals' physical and mental well-being and appear to be especially sensitive to educational outcomes on the father's side. Since ingrained socioeconomic (dis)advantages that persist over multiple generations may be indicative of social class, our results suggest that subtle attitudinal and behavioural characteristics associated with this variable may be a key factor driving health disparities.

RESUMO

Breast cancer is the most common cancer affecting women globally. Despite the significant impact of deep learning models on breast cancer diagnosis and treatment, achieving fairness or equitable outcomes across diverse populations remains a challenge when some demographic groups are underrepresented in the training data. We quantified the bias of models trained to predict breast cancer stage from a dataset consisting of 1000 biopsies from 842 patients provided by AIM-Ahead (Artificial Intelligence/Machine Learning Consortium to Advance Health Equity and Researcher Diversity). Notably, the majority of data (over 70%) were from White patients. We found that prior to post-processing adjustments, all deep learning models we trained consistently performed better for White patients than for non-White patients. After model calibration, we observed mixed results, with only some models demonstrating improved performance. This work provides a case study of bias in breast cancer medical imaging models and highlights the challenges in using post-processing to attempt to achieve fairness.

RESUMO

With postsecondary education opportunities for adult students with intellectual and developmental disabilities (IDD) on the rise, it is important to find socially validated research-based methods that are appropriate for the university or other community-based postsecondary instructional settings. The present research examines the effects of using flashcards with descriptive feedback and opportunities to respond, to teach one student with intellectual disabilities, enrolled in a postsecondary education-training program, commonly used industrial kitchen equipment. Results showed that discrete trail instruction, which included an error correction strategy of descriptive feedback plus opportunities to correctly respond was highly effective in mastery and maintenance of kitchen equipment identification, and generalization when asked to locate those items in the university kitchen lab.

RESUMO

A Geospatial Opportunity Mapping (GOMap) tool was created to identify policy unconstrained land in urban cities that is technically feasible for the deployment of solar photovoltaic power stations; and identify buildings with north- or south-facing orientation for the installation of building integrated PV (BIPV). Collaboration with a local Governing authority and a local electricity provider enabled the process to elicit comprehensive policy and technical aspect information respectively that would impact the site selection process. Five policy and four technical aspects are comprised of a total of 36 individual factors displayable by GOMap on a high-resolution city grid with a scoring system implemented to distinguish between factors that encourage or inhibits solar PV deployment. Weightings can be applied, and different scenarios explored including alternative policy changes and infrastructure upgrades. GOMap generates opportunity maps in the form of available land estimates which can be extrapolated by an in-built solar PV model to quantify annual energy generation based on local weather data, array spacing, panel type and array tilt angle. Three scenarios were devised to identify unconstrained land for solar PV deployment with varying levels of policy and technical factor relaxation, and a fourth scenario to identify dwellings for potential BIPV. These scenarios aim to tackle Glasgow City's growing energy demand and fuel poverty issue, the latter of which can supply energy to dwellings categorised as 'hard-to-heat' once heating is electrified due to the Scottish Government's Energy Strategy commitment.

RESUMO

This research investigates how entrepreneurs perceive the hypothetical nature of technologies (based on situations that are often imagined or theoretical) as a foundation for entrepreneurial endeavors and how this perception influences the formation of business Opportunity Beliefs. Drawing on the Construal Level Theory, we explore the relationship between the perceived hypotheticality of technologies and Opportunity Beliefs. Two experimental studies are conducted to examine these relationships, with Study 1 (n = 177 entrepreneurs) focusing on the perception of innovative technologies as more distant or hypothetical, and Study 2 (n = 404 entrepreneurs) delving into how the perceived distance to technology influences Opportunity Beliefs. The results indicate that entrepreneurs view more innovative technologies as more hypothetical and that hypotheticality mediates the relationship between the perceived degree of innovation and Opportunity Beliefs. We find evidence that Entrepreneurs tend to view the feasibility and fit/alignment of business opportunities more favorably when they perceive the psychological distance (hypotheticality) of the opportunity as closer rather than more distant. However, the difference this difference is nonsignificant in how they evaluate the desirability of the opportunity in any psychological distance. These results provide insight into the cognitive processes of entrepreneurs and offer implications for understanding how entrepreneurs perceive and evaluate business opportunities.

RESUMO

Intergenerational mobility captures the distance between the socioeconomic positions of parents versus their adult children. Researchers measure this distance in absolute and relative units, such as absolute dollars and relative ranks. Absolute and relative mobility often diverge. For example, absolute mobility can rise while relative mobility declines. How should scholars and policymakers understand this divergence? We conclude that they should understand it as follows: absolute mobility is less reflective than relative mobility of marginalized children's socioeconomic disadvantages. We base this conclusion on analyses of survey, administrative, and simulated data on income mobility in the contemporary United States. We analyze multiple points of difference in mobility, which facilitates the recognition of several asymmetries. First, high-income children's experiences weigh more heavily in absolute-mobility trends than low-income children's experiences, particularly when economic growth is positive. Second, this asymmetry is more characteristic of absolute- than relative-mobility trends. Third, absolute-mobility differences across demographic groups are more prone than relative-mobility differences to obscure marginalized groups' socioeconomic disadvantages. These asymmetries have policy implications: We caution that focusing on absolute mobility as a policy target can divert attention away from society's most disadvantaged children.

RESUMO

Livability, or how a place and its systems (e.g., housing, transportation) supports the ability to lead a livable life, is a determinant of health. There is a lack of standard, validated measures to assess livability in the US. This study employed factor analytic methods to create measures of livability in Connecticut using data from the DataHaven Community Wellbeing Survey (DCWS) (n = 32,262). Results identified a 3-factor model (safety, opportunity, and infrastructure) as the best fit, explaining 69% of the variance in survey items. Newly created livability measures had high internal consistency, in addition to high convergent validity with other area-level measures.

RESUMO

Despite people's general desire to avoid cognitive effort, there is a limit to our parsimony: boredom, a state defined by a lack of successful mental engagement, is found to be similarly aversive. The work presented here investigates how context - the alternative tasks present and the environmental context - impacts people's aversion to exerting cognitive effort and avoiding boredom via a demand-selection task. In a population of undergraduate students, we assessed how people's willingness to exert mental effort (in a working memory task) is affected by the presence of an easier alternative (less cognitively demanding) or a boring alternative (doing nothing at all). To manipulate environmental context, we conducted the experiment online, where participants completed the task remotely, and in a controlled laboratory setting. We find people willingly seek out effortful tasks to avoid boredom, despite avoiding high demands when both tasks on offer required some effort. We also find large effects of the participants' environmental context, with preferences for the most demanding task increasing by over 150% in the lab compared to online. These results bear relevance to theories that argue the costs of effort are determined relative to the alternatives available (e.g., opportunity cost theories). Moreover, the results demonstrate that researchers who deliberately (or inadvertently) manipulate effort and boredom must consider the effects context (both choice and environmental) may have on people's behaviour.

RESUMO

COVID-19 was the first pandemic of the internet age. Beginning at a time of great societal division in the United States (and globally), pandemic responses were further beleaguered by the viral proliferation of information, disinformation, and propaganda-collectively, an "infodemic." Polarized, blinkered views of the crisis precluded a balanced consideration of objectives, opportunities, and ineluctable trade-offs between the risks of actions and corresponding inactions. The results were lapses in both directions, greatly amplifying the pandemic toll. Persistence of this costly fractiousness is now spawning monocular critiques of the pandemic response, with neglect of essential nuance. There is a better pandemic that might have been, and the chance for far better responses to the next- but only if the follies of this history are lessons learned and applied. Failing that, the risk looms that having been amply forewarned of our liabilities, we will fail to be forearmed.

RESUMO

OBJECTIVES: Patients with a delayed diagnosis of diabetes are more likely to present in diabetic ketoacidosis (DKA). The objective of this study was to assess the prevalence, risk factors, and consequences of missed pediatric diabetes diagnoses in emergency departments (EDs) potentially leading to DKA. METHODS: Cases of children under 19 years old with a first-time diagnosis of diabetes mellitus presenting to EDs in DKA were drawn from the Healthcare Cost and Utilization Project database. A total of 11,716 cases were included. A delayed diagnosis of diabetes leading to DKA was defined by an ED discharge in the 14 days prior to the DKA diagnosis. The delayed diagnosis cases were analyzed using multivariate analysis to identify risk factors associated with delay, with the primary exposure being child opportunity index (COI) and secondary exposure being race/ethnicity. Rates of complications were compared across groups. RESULTS: Delayed diagnosis of new onset diabetes leading to DKA occurred in 2.9 %. Delayed diagnosis was associated with COI, with 4.5 , 3.5, 1.9, and 1.5 % occurring by increasing COI quartile (p<0.001). Delays were also associated with younger age and non-Hispanic Black race. Patients with a delayed diagnosis were more likely to experience complications (4.4 vs. 2.2 %, p=0.01) including mechanical ventilation, as well as more frequent intensive care unit admissions and longer length of stays. CONCLUSIONS: Among children with new-onset DKA, 2.9 % had a delayed diagnosis. Delays were associated with complications. Children living in areas with lower child opportunity and non-Hispanic Black children were at higher risk of delays.

RESUMO

This paper proposes a pseudo-birth-cohort approach to deal with a lack of longitudinal data to measure health inequities over time. Using Roemer's framework for inequality of opportunity, this study measures ex-ante and ex-post inequalities in malnutrition, a concept that spans both sides of the nutrition continuum. The total contribution of observed circumstances and the direct contribution of observed efforts to the variation of malnutrition are disentangled for people born between 1983 and 1988 in Mexico. Results indicate that inequality of opportunity has been persistent across this 30-year lifespan for that cohort. Some evidence suggests that a lack of opportunities has been transmitted from parents to children and that people's circumstances account for most of the explained variation in the double burden of malnutrition. However, stratifying the analysis by sex shows that efforts account for more of the explained variation of inequality of opportunity for women in their middle adulthood than for men in most of the outcomes analyzed.

RESUMO

Communication accessibility has been defined by many scholars and organizations, but it is generally described as clear communication that everyone can access and understand. The objective of this manuscript was to assess communication accessibility for people who use augmentative and alternative communication (AAC) within a variety of restaurant settings through interviewing five adults who utilize AAC as their primary form of communication. Interviews were qualitatively coded and revealed common communication accessibility themes restaurants and restaurant staff were not implementing, such as direct communication and increasing AAC awareness. The implications of the interview data include its potential usage in training restaurant staff and management to utilize communication accessibility tips and features to increase the communication accessibility of the restaurant patrons they serve, especially for individuals who use AAC. This could then lead researchers in creating a formal training schema for restaurants to implement into their businesses reliably and effectively.

RESUMO

PURPOSE: Though research indicates that certain aspects of adverse neighborhood conditions may influence weight development in childhood and adolescence, it is unknown if the Child Opportunity Index (COI), a composite measure of 29 indicators of neighborhood conditions, is associated with weight outcomes in adolescence. We hypothesized that lower COI would be associated with higher overweight and obesity in cross-sectional and longitudinal modeling in a national sample of 9 year olds and 10 year olds and that this association would be different by sex. METHODS: Using data from the Adolescent Brain Cognitive Development study (n = 11,857), we examined the cross-sectional association between COI quintile and overweight and obesity in 9 year olds and 10 year olds. Additionally, we used hazard ratios to examine incident overweight and obesity across three waves of data collection. RESULTS: Due to the interaction between sex and COI (p < .05), we present sex-specific models. There was a stepwise bivariate association, in which higher COI was associated with lower obesity prevalence. This pattern held in multilevel models, with a stronger association in females. In models adjusted for individual and household characteristics, female adolescents in the lowest quintile COI neighborhoods had 1.81 (95% confidence interval: 1.32, 2.48) times the odds of obesity compared to those in the highest quintile. In longitudinal models, the COI was associated with incident obesity in females only: adjusted hazard ratio = 4.27 (95% confidence interval: 1.50, 12.13) for lowest compared to highest COI. DISCUSSION: Neighborhood opportunity is associated with risk of obesity in pre-adolescence into mid-adolescence. Females may be particularly influenced by neighborhood conditions.

RESUMO

INTRODUCION: The concept of a window of opportunity in hidradenitis suppurativa (HS) management suggests that early initiation of biological therapy leads to better outcomes, though its timing remains uncertain. METHODS: We conducted a retrospective observational multicenter study, including consecutive patients with moderate to severe HS who initiated secukinumab treatment following prior failure with systemic antibiotics or adalimumab. Therapeutic burden was defined as the sum of previous systemic treatment cycles and previous major surgical interventions for HS. Patients were followed up for 24 weeks. Main outcomes were safety and effectiveness, assessed through the proportion of patients achieving HS Clinical Response (HiSCR) and a 55% reduction in International HS Severity Score System (IHS4-55). Additionally, potential predictors of response to secukinumab were studied. Analysis was performed on an intention-to-treat basis. RESULTS: A total of 67 patients (33 men, 34 women) were included, with a mean age of 41.55 (11.94) years and a mean baseline IHS4 of 17.88 (11.13). The mean therapeutic burden was 6.06 (3.49). At week 24, 10.45% (7/67) of patients experienced adverse events, with three leading to treatment discontinuation. At week 24, 41.79% (28/67) of patients achieved HiSCR, and 44.78% (30/67) of patients achieved IHS4-55. HiSCR could not be calculated in 12 patients with a baseline AN count < 3. A lower therapeutic burden was significantly associated with a higher likelihood of achieving HiSCR and IHS4-55 at week 24. CONCLUSIONS: Secukinumab showed safety and efficacy in real-world patients with HS, and the inverse correlation found between therapeutic burden and treatment response supports the concept of a window of opportunity, offering insights into its timing.

RESUMO

Entrepreneurial intention is crucial in fostering an entrepreneurial culture and driving economic growth, especially among students from higher education institutions. Our study aims to examine the role of the Theory of Planned Behavior (TPB), specifically attitude towards entrepreneurship (ATE) and perceived behavioral control (PBC), in the relationships between proactive personality (PP), entrepreneurship education (EE), entrepreneurial opportunity (EO), and entrepreneurial intention (EI) among final-year students higher education institutions in China. The TPB framework provides a theoretical foundation to investigate how psychological factors, such as ATE and PBC, mediate an individual's intention to engage in entrepreneurial behavior. The research model was analyzed using PLS-SEM. The findings, derived from a sample of 250 final-year students from public universities in China, indicate that ATE and PBC mediate the relationships between PP, EO, and EI. However, only ATE was found to mediate the relationship between EE and EI. Our findings offer insights into the foundational mechanisms driving EI, significantly advancing the scholarly understanding of entrepreneurial behavior. By demonstrating the applicability of the TPB framework, our study sheds light on the psychological processes that underlie the connections between PP, EE, EO and EI.

RESUMO

OBJECTIVES: Perceived organizational support (POS) represents the extent to which employees believe their organization values their contributions and well-being. Although higher POS is associated with increased work engagement and learning motivation, the intricacies of this relationship, especially the mediation by occupational future time perspective (OFTP), are not well understood. METHODS: We conducted an online survey of 2046 working individuals aged 20-69 to assess the relationships between POS and 2 outcome variables, learning goal orientation (LGO) and work engagement, with multiple regression analyses for all ages and in the younger age group (under 45). Then, the mediating effects of focus on opportunity (FOO)-a primary component of OFTP-on these relationships were examined. RESULTS: Of 2046 participants, 887 were younger than 45 years. Younger participants, predominantly more educated and inclined toward professional jobs, exhibited higher LGO but lower work engagement compared with their older counterparts. POS showed positive correlations with LGO, and FOO significantly mediated the relationship, especially in the young group. Furthermore, a positive relationship between POS and work engagement was noted, with FOO as a partial mediator. CONCLUSIONS: POS correlates positively with both LGO and work engagement across various age demographics, with FOO critically mediating this relationship. To enhance employee engagement and learning motivation, organizations should emphasize bolstering both POS and FOO.

RESUMO

AbstractAn individual's access to mates (i.e., its "mating potential") can constrain its reproduction but may also influence its fitness through effects on offspring survival. For instance, mate proximity may correspond with relatedness and lead to inbreeding depression in offspring. While offspring production and survival might respond differently to mating potential, previous studies have not considered the simultaneous effects of mating potential on these fitness components. We investigated the relationship of mating potential with both production and survival of offspring in populations of a long-lived herbaceous perennial, Echinacea angustifolia. Across 7 years and 14 sites, we quantified the mating potential of maternal plants in 1,278 mating bouts and followed the offspring from these bouts over 8 years. We used aster models to evaluate the relationship of mating potential with the number of offspring that emerged and that were alive after 8 years. Seedling emergence increased with mating potential. Despite this, the number of offspring surviving after 8 years showed no relationship to mating potential. Our results support the broader conclusion that the effect of mating potential on fitness erodes over time because of demographic stochasticity at the maternal level.
