With age, the quality of emotions may shift from negative in tone to positive, but also from active to passive. The shift from negative to positive is consistent with the age as maturity perspective. The shift from active to passive supports the age as decline perspective. If these generalities are correct, then they should apply to positive emotions as well as negative emotions. We should see a shift in positive emotions from active (excitement) to passive (serenity), as well as in the negative emotions (from the agitation of anxiety and anger to the lethargy of depression). In order to accurately portray the shifts in emotional tone, age may best be considered as simultaneously indicating maturity and decline. This paper examines results from the emotions module of the 1996 U.S. General Social Survey and finds support for the idea that age is associated with a shift from negative to positive and from active to passive emotions.

The cumulative advantage hypothesis predicts that the adulthood rate of decline in health differs across levels of education in a manner that progressively enlarges the health gap across most or all of adulthood. The rising importance hypothesis predicts that the differences across levels of education in the rate of health's decline have been growing for many decades. If both are correct, then each phenomenon tends to obscure the other when comparing the health gap across age groups in a particular year or period. The trend also can make it seem that health converges across levels of education in old age when it actually diverges. A latent-growth model of U.S. data from 1995, 1998, and 2001 supported both hypotheses. It also showed a trend toward lower age-specific self-rated health at all levels of education, but less so the higher the education. There was no significant convergence over time in older age groups. [ABSTRACT FROM AUTHOR]

Neighborhood context could affect health behaviors because of structure or contagion. We expected that residents of US neighborhoods where a high percentage of residents are poor and do not have college degrees would be more likely to smoke and less likely to walk and exercise. We examined the hypotheses using multi-level data in which survey information from a representative sample of Illinois residents is linked to census-tract information about poverty and education in their neighborhood. Contrary to expectations we found that residents of poor neighborhoods were more likely to walk than those in less disadvantaged places, adjusting for individual poverty, household income, education, race, ethnicity, sex, age, and marital status. This was the case despite the fact that residents of poor neighborhoods were more afraid to leave the house and feared being victimized on the streets. Consistent with expectations we found that residents of neighborhoods where a high percentage of residents are college educated are more likely to walk. Thus, the two aspects of neighborhood socioeconomic status had opposite effects on walking. Neighborhood context had no effect on the likelihood of exercising strenuously. Men in poor neighborhoods were more likely to smoke than those in less disadvantaged places, but neighborhood context had no significant effect on women's likelihood of smoking.

Kisspeptin is a major regulator of gonadotropin secretion in pigs. Previously, CRISPR/Cas9 knockout of KISS1 was used to develop a mosaic parental line of pigs to generate offspring that would not need castration due to loss of kisspeptin. The current goal was to characterize growth and reproductive development of F1 pigs from this parental line. Body weights, gonadotropin concentrations and gonadal development were measured from birth through development (boars to 220 d of age, n = 42; gilts to 160 d of age, n = 36). Testosterone, skatole, and androstenone were also measured in boars. Blood samples were collected by jugular venipuncture for quantification of serum hormones, gonadal tissues collected for gross morphology and histology, and a fat biopsy collected (boars) for skatole and androstenone analysis. Body weight did not differ with genotype. There were no differences between KISS1+/+ and heterozygote KISS1+/- animals for most parameters measured. Gonadotropin concentrations were reduced in KISS1-/- boars and gilts compared with KISS1+/+ and KISS1+/- animals (P < 0.05). Concentrations of testosterone in serum and both androstenone and skatole in adipose were less in KISS1-/- boars than in KISS1+/+ and KISS1+/- boars (P < 0.05). Hypogonadism was in all KISS1-/- gilts and boars. These data indicate that knocking out KISS1 causes hypogonadotropic hypogonadism but does not negatively affect growth in pigs. Only one KISS1 allele is needed for normal gonadotropin secretion and gonadal development, and accumulation of compounds in adipose leading to boar taint., (Published by Oxford University Press on behalf of Society for the Study of Reproduction 2024.)

Aim: A major barrier to performing cardiac arrest trials is the requirement for prospective informed consent, which is often infeasible during individual medical emergencies. In an effort to improve outcomes, some governments have adopted legislation permitting research without prior consent (RWPC) in these circumstances. We aimed to outline key differences between legislation in four Western locations and explore the effects of these differences on trial design and implementation in cardiac arrest research., Data Sources: We performed a narrative review of RWPC legislation in the United States (US), Canada, the European Union (EU) and the United Kingdom (UK)., Results: The primary criteria required to perform RWPC was similar across locations: the study must involve an individual medical emergency during which neither the prospective subject nor their authorized representative can provide informed consent. The US regulations were unique in their requirements for performing Community Consultation and Public Disclosure in the communities in which the research takes place. Another major difference was the requirement for consent for ongoing participation in Canada, the EU and the UK, while only notification of enrollment and the opportunity to discontinue participation are required in the US. Additionally, only Canada and the EU explicitly state that the subject or their representative may request withdrawal of their data., Conclusion: Regulations governing RWPC in the US, Canada, the EU and the UK have similar goals and protections for vulnerable populations during medical emergencies. Differences in the qualifying criteria and implementation procedures exist across locations and may affect study design., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Author(s).)

The pig represents the only livestock mammal capable of producing a functional protein for the second mammalian form of gonadotropin-releasing hormone (GnRH-II) and its receptor (GnRHR-II). To examine the role of GnRH-II and its receptor in pig reproduction, we produced a unique swine line with ubiquitous knockdown of endogenous GnRHR-II levels (GnRHR-II knockdown [KD]), which is largely the focus of this review. In mature GnRHR-II KD males, circulating testosterone concentrations were 82% lower than littermate control boars, despite similar luteinizing hormone (LH) levels. In addition, nine other gonadal steroids were reduced in the serum of GnRHR-II KD boars, whereas adrenal steroids (except 11-deoxycortisol) did not differ between lines. Interestingly, testes from GnRHR-II KD males had fewer, hypertrophic Leydig cells and fewer, enlarged seminiferous tubules than control testes. As expected, downstream reproductive traits such as androgen-dependent organ weights and semen characteristics were also significantly reduced in GnRHR-II KD versus control boars. Next, we explored the importance of this novel ligand/receptor complex in female reproduction. Transgenic gilts had fewer, but heavier, corpora lutea with smaller luteal cells than littermate control females. Although the number of antral follicles were similar between lines, the diameter of antral follicles tended to be larger in GnRHR-II KD females. In regard to steroidogenesis, circulating concentrations of progesterone and 17β-estradiol were lower in transgenic compared to control gilts, even though serum levels of follicle-stimulating hormone and LH were similar. Thus, GnRH-II and GnRHR-II represent a potential avenue to enhance fertility and promote the profitability of pork producers., (© 2022 Wiley Periodicals LLC.)

Aim: To explore perspectives of families in the pediatric intensive care unit (PICU) about an emergency interventional trial on peri-arrest bolus epinephrine for acute hypotension using Exception From Informed Consent (EFIC)., Methods: We performed face-to-face interviews with families whose children were hospitalized in the PICU. A research team member provided an educational presentation about the planned trial and administered a survey with open- and closed-ended items. Analyses included descriptive statistics for quantitative data and thematic analysis for qualitative data., Results: Sixty-seven participants contributed to 60 survey responses (53 individuals and 7 families for whom 2 family members participated). Most participants answered favorably toward the planned trial: 55/58 (95%) reported that the trial seemed "somewhat" or "very important"; 52/57 (91%) felt the use of EFIC was "somewhat" or "completely acceptable"; and 43/58 (74%) said they would be "somewhat" or "very likely" to allow their child to participate. Five themes emerged supporting participation in the planned trial: 1) trust in the clinical team; 2) familiarity with the study intervention (epinephrine); 3) study protocol being similar to standard care; 4) informed consent during an emergency was not feasible; and 5) importance of research. Barriers to potential participation included requests for additional time to decide about participating and misconceptions about study elements, especially eligibility., Conclusions: Families of PICU patients generally supported plans for an emergency interventional trial using EFIC. Future inpatient EFIC studies may benefit from highlighting the themes identified here in their educational materials., (© 2023 The Authors.)

Objectives: To describe trends in critical illness from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children over the course of the COVID-19 pandemic. We hypothesized that PICU admission rates were higher in the Omicron period compared with the original outbreak but that fewer patients needed endotracheal intubation., Design: Retrospective cohort study., Setting: This study took place in nine U.S. PICUs over 3 weeks in January 2022 (Omicron period) compared with 3 weeks in March 2020 (original period)., Patients: Patients less than or equal to 21 years old who screened positive for SARS-CoV-2 infection by polymerase chain reaction or hospital-based rapid antigen test and were admitted to a PICU or intermediate care unit were included., Interventions: None., Measurements and Main Results: A total of 267 patients (239 Omicron and 28 original) were reviewed. Forty-five patients in the Omicron cohort had incidental SARS-CoV-2 and were excluded from analysis. The Omicron cohort patients were younger compared with the original cohort patients (median [interquartile range], 6 yr [1.3-13.3 yr] vs 14 yr [8.3-17.3 yr]; p = 0.001). The Omicron period, compared with the original period, was associated with an average increase in COVID-19-related PICU admissions of 13 patients per institution (95% CI, 6-36; p = 0.008), which represents a seven-fold increase in the absolute number admissions. We failed to identify an association between cohort period (Omicron vs original) and odds of intubation (odds ratio, 0.7; 95% CI, 0.3-1.7). However, we cannot exclude the possibility of up to 70% reduction in intubation., Conclusions: COVID-19-related PICU admissions were seven times higher in the Omicron wave compared with the original outbreak. We could not exclude the possibility of up to 70% reduction in use of intubation in the Omicron versus original epoch, which may represent differences in PICU/hospital admission policy in the later period, or pattern of disease, or possibly the impact of vaccination., Competing Interests: Dr. Ross’ institution received funding from the National Heart, Lung, and Blood Institute (K23HL148312).

Objective: This study aimed to describe baseline and event characteristics and outcomes for adult patients who experience in-hospital cardiac arrest (IHCA) in a quaternary children's hospital and compare IHCA outcomes in younger (18-24 years) versus older (≥25 years) adults. We hypothesized that the rate of survival to hospital discharge would be lower in the older adult group., Methods: We performed a retrospective single-center cohort study of inpatient areas of a quaternary children's center. Adult patients (≥18 years of age) with an index pulseless IHCA requiring at least 1 minute of cardiopulmonary resuscitation or defibrillation were included., Results: Thirty-three events met the inclusion criteria with a median patient age of 23.9 years (interquartile range, 20.2-33.3 years). Twenty-one (64%) patients had congenital heart disease, and 25 (76%) patients had comorbidities involving ≥2 organ systems. The most common prearrest interventions were invasive mechanical ventilation (76%) and vasoactive infusions (55%). Seventeen patients (52%) survived to hospital discharge.Survival to discharge was lower in patients 25 years or older compared with patients aged 18 to 24 years old (3 of 15 [20%] vs 14 of 18 [78%], respectively; P = 0.002)., Conclusions: The majority of adult patients with IHCA in our pediatric hospital had preexisting multisystem comorbidities, the most common of which was congenital heart disease. Overall survival to discharge after IHCA was 52%, similar to that reported for the general pediatric population. Survival to discharge was significantly lower in the subgroup of patients 25 years or older when compared with those between the ages of 18 and 24 years., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Objectives: Differences between adult and pediatric in-hospital cardiac arrest (IHCA) are well-described. Although most adults are cared for on adult services, pediatric services often admit adults, particularly those with chronic conditions. The objective of this study is to describe IHCA in adults admitted to pediatric services., Design: Retrospective cohort analysis from the American Heart Association's Get With The Guidelines-Resuscitation registry of a subpopulation of adults with IHCA while admitted to pediatric services. Multivariable logistic regression was used to evaluate adjusted survival outcomes and compare outcomes between age groups (18-21, 22-25, and ≥26 yr old)., Setting: Hospitals contributing to the Get With The Guidelines-Resuscitation registry., Patients: Adult-aged patients (≥ 18 yr) with an index pulseless IHCA while admitted to a pediatric service from 2000 to 2018., Interventions: None., Measurements and Main Results: A total of 491 adult IHCAs were recorded on pediatric services at 17 sites, during the 19 years of review, and these events represented 0.1% of all adult IHCAs. In total, 221 cases met inclusion criteria with 139 events excluded due to an initial rhythm of bradycardia with poor perfusion. Median patient age was 22 years (interquartile range, 19-28 yr). Ninety-eight percent of patients had at least one pre-existing condition. Return of spontaneous circulation occurred in 63% of events and 30% of the patients survived to discharge. All age groups had similar rates of survival to discharge (range 26-37%; p = 0.37), and survival did not change over the study period (range 26-37%; p = 0.23 for adjusted survival to discharge)., Conclusions: In this cohort of adults with IHCA while admitted to a pediatric service, we failed to find an association between survival outcomes and age.

Introduction: In 2014, the Joint United Nations Programme on HIV/AIDS set an 'ambitious' 90-90-90 target for 2020. By 2016, there were disparities observed among countries in their progress towards the targets and some believed the targets were not achievable. In this report, we present the results of data from the Ethiopia Population-based HIV Impact Assessment survey analyzed to assess progress with the targets and associated factors., Methods: We conducted a nationally representative survey in urban areas of Ethiopia. Socio-demographic and behavioural data were collected from consenting participants using a structured interview. HIV testing was done following the national HIV rapid testing algorithm and seropositivity confirmed using a supplemental laboratory assay. HIV viral suppression was considered if the viral load was <1,000 RNA copies/ml. Screening antiretroviral drugs was done for efavirenz, lopinavir, and tenofovir, which were in use during the survey period. In this analysis, we generated weighted descriptive statistics and used bivariate and logistic regression analysis to examine for associations. The 95% confidence interval was used to measure the precision of estimates and the significance level set at p<0.05., Results: Of 19,136 eligible participants aged 15-64 years, 614 (3% [95% CI: 0.8-3.3]) were HIV-positive, of which 79.0% (95% CI: 4.7-82.7) were aware of their HIV status, and 97.1% (95% CI: 95.0-98.3 were on antiretroviral therapy, of which 87.6% (95% CI: 83.9-90.5) achieved viral load suppression. Awareness about HIV-positive status was significantly higher among females (aOR = 2.8 [95% CI: 1.38-5.51]), significantly increased with age, the odds being highest for those aged 55-64 years (aOR = 11.4 [95% CI: 2.52-51.79]) compared to those 15-24 years, and was significantly higher among those who used condom at last sex in the past 12 months (aOR = 5.1 [95% CI: 1.68-15.25]). Individuals with secondary education and above were more likely to have achieved viral suppression (aOR = 8.2 [95% CI: 1.82-37.07]) compared with those with no education., Conclusion: Ethiopia made encouraging progress towards the UNAIDS 90-90-90 targets. The country needs to intensify its efforts to achieve the targets. A particular focus is required to fill the gaps in knowledge of HIV-positive status to increase case identification among population groups such as males, the youth, and those with low education., Competing Interests: I have read the journal’s policy and the authors of this manuscript have the following competing interests. None of the authors have any conflict on interest.

Aim: To describe current practices of peri-arrest bolus epinephrine use amongst pediatric resuscitation experts in a multinational survey., Methods: A 9-question survey was developed and electronically distributed to pediatric critical care physicians who are site investigators for the Pediatric Resuscitation Quality Collaborative (pediRES-Q) network. Institutional demographics were collected through the American Hospital Association 2018 Annual Survey and linked to responses. Descriptive statistics were used to characterize closed-ended responses, and qualitative content analysis to analyze open-ended responses., Results: Of the 63 collaborative members invited to participate, 49 (78%) responded, representing 35 institutions in 9 countries. Forty-six of the 49 respondents (94%) reported that they would consider using peri-arrest bolus epinephrine during critical situations in patients not requiring cardiopulmonary resuscitation. Initial dosing strategies ranged from 0.1mcg/kg to 10mcg/kg, with the most commonly reported initial dose of 1mcg/kg by 25 of the 37 (68%) respondents who answered this question. Three of the 49 (6%) participants indicated that they would generally avoid using peri-arrest bolus epinephrine, citing lack of evidence to support its use., Conclusions: In this multinational survey of pediatric resuscitation experts, endorsement of peri-arrest bolus epinephrine use was nearly universal, though a few clinicians cited lack of evidence to support this practice. There was a 100-fold difference in the range of initial weight-based doses reported, as well as a minority of clinicians who reported using non-weight-based dosing. Further research is needed to determine best practices, standardization of initial dosing, clinical factors that may warrant dosing modifications and associations with clinically important outcomes., (© 2022 The Authors.)

Parent stress has been associated with negative outcomes for youth and may be particularly high during adolescence. Mindfulness interventions have the potential to reduce parent stress and to improve parenting behavior and parent-child relationship quality. The present randomized controlled study examined effects of a parenting-focused mindfulness intervention, the Parenting Mindfully (PM) intervention, for highly stressed parents of adolescents. Eighty three mothers of 12-17 year olds reporting high stress were randomly assigned to the PM intervention or to a minimal-intervention Parent Education (PE) control group. At pre- and post-intervention, mothers reported on their mindfulness, stress, parenting stress, mindful parenting, and parent-adolescent relationship quality. At pre- and post-intervention, mothers' observed parenting behaviors and reported negative emotional responses to a laboratory parent-adolescent interaction task (PAIT) were also collected. Findings indicated that the PM intervention, compared to PE, increased mothers' mindfulness, reduced parenting stress in two domains, increased mindful parenting related to emotional awareness in parenting, and improved parent-adolescent relationship quality. For mothers of girls (but not mothers of boys), the PM intervention also decreased negative parenting behavior and decreased negative emotional responses in PAIT. Effects sizes were medium to large. In sum, findings support parenting-focused mindfulness training as a viable intervention strategy for highly-stressed parents., Competing Interests: Conflicts of Interest: Author Sinha is on the scientific advisory board for Embera NeuroTherapeutics, Inc.

Aims: To describe trends in pediatric in-hospital cardiac arrest drug administration and to assess temporal associations of the Pediatric Advanced Life Support (PALS) guideline changes with drug usage., Methods: Pediatric patients <18 years old with in-hospital cardiac arrest recorded in the American Heart Association Get With The Guidelines-Resuscitation database between 2002 and 2018 were included. The annual adjusted odds of receiving each intra-arrest medication was determined. The association between changes in the PALS Guidelines and medication use over time was assessed interrupted time series analyses., Results: A total of 6107 patients were analyzed. The adjusted odds of receiving lidocaine (0.33; 95% CI, 0.18, 0.61; p < 0.001), atropine (0.19; 95% CI 0.12, 0.30; p < 0.001) and bicarbonate (0.54; 95% CI 0.35, 0.86; p = 0.009) were lower in 2018 compared to 2002. For lidocaine, there were no significant changes in the step (-2.1%; 95% CI, -5.9%, 1.6%; p = 0.27) after the 2010 or 2015 (Step: -1.5%; 95% CI, -8.0%, 5.0; p = 0.65) guideline releases. There were no significant changes in the step for bicarbonate (-2.3%; 95% CI, -7.6%, 3.0%; p = 0.39) after the 2010 updates. For atropine, there was a downward step change after the 2010 guideline release (-5.9%; 95% CI, -10.5%, -1.3%; p = 0.01)., Conclusions: Changes to the PALS guidelines for lidocaine and bicarbonate were not temporally associated with acute changes in the use of these medications; however, better alignment with these updates was observed over time. A minor update to the language surrounding atropine in the PALS text was associated with a modest acute change in the observed use of atropine. Future studies exploring other factors that influence prescribers in pediatric IHCA are needed., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Importance: The recent and ongoing coronavirus disease 2019 (COVID-19) pandemic has taken an unprecedented toll on adults critically ill with COVID-19 infection. While there is evidence that the burden of COVID-19 infection in hospitalized children is lesser than in their adult counterparts, to date, there are only limited reports describing COVID-19 in pediatric intensive care units (PICUs)., Objective: To provide an early description and characterization of COVID-19 infection in North American PICUs, focusing on mode of presentation, presence of comorbidities, severity of disease, therapeutic interventions, clinical trajectory, and early outcomes., Design, Setting, and Participants: This cross-sectional study included children positive for COVID-19 admitted to 46 North American PICUs between March 14 and April 3, 2020. with follow-up to April 10, 2020., Main Outcomes and Measures: Prehospital characteristics, clinical trajectory, and hospital outcomes of children admitted to PICUs with confirmed COVID-19 infection., Results: Of the 48 children with COVID-19 admitted to participating PICUs, 25 (52%) were male, and the median (range) age was 13 (4.2-16.6) years. Forty patients (83%) had significant preexisting comorbidities; 35 (73%) presented with respiratory symptoms and 18 (38%) required invasive ventilation. Eleven patients (23%) had failure of 2 or more organ systems. Extracorporeal membrane oxygenation was required for 1 patient (2%). Targeted therapies were used in 28 patients (61%), with hydroxychloroquine being the most commonly used agent either alone (11 patients) or in combination (10 patients). At the completion of the follow-up period, 2 patients (4%) had died and 15 (31%) were still hospitalized, with 3 still requiring ventilatory support and 1 receiving extracorporeal membrane oxygenation. The median (range) PICU and hospital lengths of stay for those who had been discharged were 5 (3-9) days and 7 (4-13) days, respectively., Conclusions and Relevance: This early report describes the burden of COVID-19 infection in North American PICUs and confirms that severe illness in children is significant but far less frequent than in adults. Prehospital comorbidities appear to be an important factor in children. These preliminary observations provide an important platform for larger and more extensive studies of children with COVID-19 infection.

Aim: To determine whether the use of epinephrine in pediatric patients receiving cardiopulmonary resuscitation for bradycardia and poor perfusion was associated with improved clinical outcomes., Methods: Using the Get With The Guidelines-Resuscitation registry, we included pediatric patients (≤18 years) who received in-hospital cardiopulmonary resuscitation for bradycardia with poor perfusion (non-pulseless event) between January 2000 and December 2018. Time-dependent propensity score matching was used to match patients receiving epinephrine within the first 10 min of resuscitation to patients at risk of receiving epinephrine within the same minute., Results: In the full cohort, 55% of patients were male and 39% were neonates. A higher number of patients receiving epinephrine required vasopressors and mechanical ventilation prior to the event compared to those not receiving epinephrine. A total of 3528 patients who received epinephrine were matched to 3528 patients at risk of receiving epinephrine based on the propensity score. Epinephrine was associated with decreased survival to hospital discharge (RR, 0.79 [95% CI, 0.74-0.85]; p < 0.001), return of spontaneous circulation (RR, 0.94 [95% CI, 0,91-0.96]; p < 0.001), 24-h survival (RR, 0.85 [95% CI, 0.81-0.90]; p < 0.001), and favorable neurological outcome (RR, 0.76 [95% CI, 0.68-0.84]; p < 0.001). Epinephrine was also associated with an increased risk of progression to pulselessness (RR, 1.17 [95% CI, 1.06-1.28]; p < 0.001)., Conclusion: In children receiving cardiopulmonary resuscitation for bradycardia with poor perfusion, epinephrine was associated with worse outcomes, although the study does not eliminate the potential for confounding., (Copyright © 2020 Elsevier B.V.

Background: Lidocaine and amiodarone are both included in the pediatric cardiac arrest guidelines as treatments of shock-refractory ventricular fibrillation or pulseless ventricular tachycardia, although there is limited evidence to support this recommendation., Methods: In this cohort study from the Get With The Guidelines - Resuscitation registry, we included pediatric patients (≤18 years) with an in-hospital cardiac arrest between 2000 and 2018, who presented with an initial or subsequent shockable rhythm (ventricular fibrillation and pulseless ventricular tachycardia). Patients receiving amiodarone were matched to patients receiving lidocaine based on a propensity score, calculated from multiple patient, event, and hospital characteristics., Results: A total of 365 patients were available for the analysis, of which 180 (49%) patients were matched on the propensity score. The median age in the raw cohort was 6 (quartiles, 0.5-14) years, 164 (45%) patients were female, and 238 (65%) patients received an antiarrhythmic for an initial shockable rhythm. In the matched cohort, there were no statistically significant differences between patients receiving lidocaine compared to amiodarone in return of spontaneous circulation (RR, 0.99 [95%CI, 0.82-1.19]; p = 0.88), survival to 24 h (RR, 1.02 [95%CI, 0.76-1.38]; p = 0.88), survival to hospital discharge (RR, 1.01 [95%CI, 0.63-1.63]; p = 0.96), and favorable neurological outcome (RR, 0.65 [95%CI, 0.35-1.21]; p = 0.17). The results remained consistent in multiple sensitivity analyses., Conclusions: In children with cardiac arrest receiving antiarrhythmics for a shockable rhythm, there was no significant difference in clinical outcomes between those receiving lidocaine compared to amiodarone., (Copyright © 2020 Elsevier B.V.

Objectives: To describe and compare patient and event characteristics and outcomes in pediatric massive pulmonary embolism (MPE) and submassive pulmonary embolism (SMPE)., Methods: A retrospective cohort study at a quaternary-care pediatric hospital was conducted. Patients age <19 years with MPE (acute pulmonary embolism [PE] with cardiac arrest, hypotension, or compensated shock due to PE) or SMPE (right ventricular strain due to acute PE) between January 1997 and June 2019 were included., Results: Thirty-three patients were identified, including 9 (27%) patients with MPE and 24 (73%) patients with SMPE. The most commonly identified risk factor was use of oral contraceptive pills in 16 (49%) patients. Six (18%) patients died, 3 (9%) of which were PE-related deaths. Before PE, patients with MPE were more likely to be hospitalized (89% vs 13%, P < .001), have major comorbidities (89% vs 25%, P = .002), central venous catheters (67% vs 17%, P = .01), critical illness (56% vs 8%, P = .009), immobility (67% vs 13%, P = .005), and be postoperative (44% vs 4%, P = .01). MPE patients were also more likely to die before discharge (56% vs 4%, P = .003). Both groups were equally likely to have primary reperfusion attempts (78% of MPE versus 67% of SMPE, P = .69)., Conclusions: Pediatric MPE and SMPE differed in presentation, comorbidities, and risk factors, many of which were associated with hospitalization status. Pediatric-specific studies are warranted to determine risk assessment and management strategies, which may differ from adult guidelines., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2020 by the American Academy of Pediatrics.)

Background: Cardiac arrest in hospitalized children is associated with poor outcomes, but no contemporary study has reported whether the trends in survival have changed over time. In this study, we examined temporal trends in survival for pediatric patients with an in-hospital pulseless cardiac arrest and pediatric patients with a nonpulseless cardiopulmonary resuscitation event from 2000 to 2018., Methods: This was an observational study of hospitalized pediatric patients (≤18 years of age) who received cardiopulmonary resuscitation from January 2000 to December 2018 and were included in the Get With The Guidelines-Resuscitation registry, a United States-based in-hospital cardiac arrest registry. The primary outcome was survival to hospital discharge, and the secondary outcome was return of spontaneous circulation (binary outcomes). Generalized estimation equations were used to obtain unadjusted trends in outcomes over time. Separate analyses were performed for patients with a pulseless cardiac arrest and patients with a nonpulseless event (bradycardia with poor perfusion) requiring cardiopulmonary resuscitation. A subgroup analysis was conducted for shockable versus nonshockable initial rhythms in pulseless events., Results: A total of 7433 patients with a pulseless cardiac arrest and 5751 patients with a nonpulseless event were included for the analyses. For pulseless cardiac arrests, survival was 19% (95% CI, 11%-29%) in 2000 and 38% (95% CI, 34%-43%) in 2018, with an absolute change of 0.67% (95% CI, 0.40%-0.95%; P <0.001) per year, although the increase in survival appeared to stagnate following 2010. Return of spontaneous circulation also increased over time, with an absolute change of 0.83% (95% CI, 0.53%-1.14%; P <0.001) per year. We found no interaction between survival to hospital discharge and the initial rhythm. For nonpulseless events, survival was 57% (95% CI, 39%-75%) in 2000 and 66% (95% CI, 61%-72%) in 2018, with an absolute change of 0.80% (95% CI, 0.32%-1.27%; P =0.001) per year., Conclusions: Survival has improved for pediatric events requiring cardiopulmonary resuscitation in the United States, with a 19% absolute increase in survival for in-hospital pulseless cardiac arrests and a 9% absolute increase in survival for nonpulseless events between 2000 and 2018. However, survival from pulseless cardiac arrests appeared to have reached a plateau following 2010.

Temperate grasslands and woodlands are the focus of extensive restoration efforts worldwide. Reintroduction of locally extinct soil-foraging and burrowing animals has been suggested as a means to restore soil function in these ecosystems. Yet little is known about the physical and chemical effects of digging on soil over time and how these effects differ between species of digging animal, vegetation types or ecosystems. We compared foraging pits of a native reintroduced marsupial, the eastern bettong ( Bettongia gaimardi ) and that of the exotic European rabbit ( Oryctolagus cuniculus ). We simulated pits of these animals and measured pit dimensions and soil chemical properties over a period of 2 years. We showed that bettong and rabbit pits differed in their morphology and longevity, and that pits had a strong moderating effect on soil surface temperatures. Over 75% of the simulated pits were still visible after 2 years, and bettong pits infilled faster than rabbit pits. Bettong pits reduced diurnal temperature range by up to 25 °C compared to the soil surface. We did not find any effects of digging on soil chemistry that were consistent across vegetation types, between bettong and rabbit pits, and with time since digging, which is contrary to studies conducted in arid biomes. Our findings show that animal foraging pits in temperate ecosystems cause physical alteration of the soil surface and microclimatic conditions rather than nutrient changes often observed in arid areas., Competing Interests: The authors declare that they have no competing interests.

Background: Previous incidence estimates may no longer reflect the current public health burden of cardiac arrest in hospitalized adult and pediatric patients across the United States. The aim of this study was to estimate the contemporary annual incidence of in-hospital cardiac arrest in adults and children across the United States and to describe trends in incidence between 2008 and 2017., Methods and Results: Using the Get With The Guidelines– Resuscitation registry, we developed a negative binomial regression model to estimate the incidence of index pulseless in-hospital cardiac arrest based on hospital-level characteristics. The model was used to predict the number of in-hospital cardiac arrests in all US hospitals, using data from the American Hospital Association Annual Survey. We performed separate analyses for adult (≥18 years) and pediatric (<18 years) cardiac arrests. Additional analyses were performed for recurrent cardiac arrests and pediatric patients requiring cardiopulmonary resuscitation for poor perfusion (nonpulseless events). The average annual incidence of in-hospital cardiac arrest in the United States was estimated at 292 000 (95% prediction interval, 217 600–503 500) adult and 15 200 pediatric cases, of which 7100 (95% prediction interval, 4400–9900) cases were pulseless cardiac arrests and 8100 (95% prediction interval, 4700–11 500) cases were nonpulseless events. The rate of adult cardiac arrests increased over time, while pediatric events remained more stable. When including both index and recurrent inhospital cardiac arrests, the average annual incidence was estimated at 357 900 (95% prediction interval, 247 100–598 400) adult and 19 900 pediatric cases, of which 8300 (95% prediction interval, 4900–11 200) cases were pulseless cardiac arrests and 11 600 (95% prediction interval, 6400–16 700) cases were nonpulseless events., Conclusions: There are ≈292 000 adult in-hospital cardiac arrests and 15 200 pediatric in-hospital events in the United States each year. This study provides contemporary estimates of the public health burden of cardiac arrest among hospitalized patients., Competing Interests: None., (© 2019 American Heart Association, Inc.)

Objectives: Clinical providers have access to a number of pharmacologic agents during in-hospital cardiac arrest. Few studies have explored medication administration patterns during in-hospital cardiac arrest. Herein, we examine trends in use of pharmacologic interventions during in-hospital cardiac arrest both over time and with respect to the American Heart Association Advanced Cardiac Life Support guideline updates., Design: Observational cohort study., Setting: Hospitals contributing data to the American Heart Association Get With The Guidelines-Resuscitation database between 2001 and 2016., Patients: Adult in-hospital cardiac arrest patients., Interventions: The percentage of patients receiving epinephrine, vasopressin, amiodarone, lidocaine, atropine, bicarbonate, calcium, magnesium, and dextrose each year were calculated in patients with shockable and nonshockable initial rhythms. Hierarchical multivariable logistic regression was used to determine the annual adjusted odds of medication administration. An interrupted time series analysis was performed to assess change in atropine use after the 2010 American Heart Association guideline update., Measurements and Main Results: A total of 268,031 index in-hospital cardiac arrests were included. As compared to 2001, the adjusted odds ratio of receiving each medication in 2016 were epinephrine (adjusted odds ratio, 1.5; 95% CI, 1.3-1.8), vasopressin (adjusted odds ratio, 1.5; 95% CI, 1.1-2.1), amiodarone (adjusted odds ratio, 3.4; 95% CI, 2.9-4.0), lidocaine (adjusted odds ratio, 0.2; 95% CI, 0.2-0.2), atropine (adjusted odds ratio, 0.07; 95% CI, 0.06-0.08), bicarbonate (adjusted odds ratio, 2.0; 95% CI, 1.8-2.3), calcium (adjusted odds ratio, 2.0; 95% CI, 1.7-2.3), magnesium (adjusted odds ratio, 2.2; 95% CI, 1.9-2.7; p < 0.0001), and dextrose (adjusted odds ratio, 2.8; 95% CI, 2.3-3.4). Following the 2010 American Heart Association guideline update, there was a downward step change in the intercept and slope change in atropine use (p < 0.0001)., Conclusions: Prescribing patterns during in-hospital cardiac arrest have changed significantly over time. Changes to American Heart Association Advanced Cardiac Life Support guidelines have had a rapid and substantial effect on the use of a number of commonly used in-hospital cardiac arrest medications.

Aim: Limited data suggests low oxygen consumption (VO 2 ), driven by mitochondrial injury, is associated with mortality after cardiac arrest. Due to the challenges of measurement in the critically ill, post-arrest metabolism remains poorly characterized. We monitored VO 2 , carbon dioxide production (VCO 2 ) and the respiratory quotient (RQ) in post-arrest patients and explored associations with outcome., Methods: Using a gas exchange monitor, we measured continuous VO 2 and VCO 2 in post- arrest patients treated with targeted temperature management. We used area under the curve and medians over time to evaluate the association between VO 2 , VCO 2 , RQ and the VO 2 :lactate ratio with survival., Results: In 17 patients, VO 2 in the first 12 h after return of spontaneous circulation (ROSC) was associated with survival (median in survivors 3.35 mL/kg/min [2.98,3.88] vs. non-survivors 2.61 mL/kg/min [2.21,2.94], p = .039). This did not persist over 24 h. The VO 2 :lactate ratio was associated with survival (median in survivors 1.4 [IQR: 1.1,1.7] vs. non-survivors 0.8 [IQR: 0.6,1.2] p < 0.001). Median RQ was 0.66 (IQR 0.63,0.70) and 71% of RQ measurements were <0.7. Patients with initial RQ < 0.7 had 17% survival versus 64% with initial RQ > 0.7 (p = .131). VCO 2 was not associated with survival., Conclusions: There was a significant association between VO 2 and mortality in the first 12 h after ROSC, but not over 24 h. Lower VO 2: lactate ratio was associated with mortality. A large percentage of patients had RQs below physiologic norms. Further research is needed to explore whether these parameters could have true prognostic value or be a potential treatment target., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Purpose of Review: We review the recent advances in physiologic monitoring during cardiac arrest and offer an evidence-based framework for prioritizing physiologic targets during cardiopulmonary resuscitation (CPR)., Recent Findings: Current CPR guidelines recommend a uniform approach for all patients in cardiac arrest, but newer data support a precision strategy that uses the individual patient's physiology to guide resuscitation. Coronary perfusion pressure and arterial DBP are associated with survival outcomes in recent animal and human studies. End-tidal carbon dioxide is a reasonable noninvasive alternative, but may be inferior to invasive hemodynamic endpoints. Cerebral oximetry and cardiac ultrasound are emerging physiologic indicators of CPR effectiveness., Summary: Physiologic monitoring can and should be used to deliver precision CPR whenever possible and may improve outcomes after cardiac arrest.

Aim: To quantify the physiologic effects of pre-arrest bolus dilute epinephrine in the pediatric intensive care unit., Methods: Patients <18 years old and ≥37 weeks gestation who received an intravenous bolus of dilute epinephrine (10 mcg/mL) in the pediatric intensive care units at our institution from January 2011 to March 2017 were retrospectively identified. Patients were excluded if doses exceeded 20 mcg/kg, or under the following circumstances: orders limiting resuscitation, extracorporeal membrane oxygenation, active chest compressions, simultaneous administration of other blood pressure-altering interventions or documented normotension prior to epinephrine. The primary outcome was change in systolic blood pressure within 5 min of epinephrine. Patients were categorized as non-responders if the change in systolic blood pressure was ≤10 mmHg., Results: One hundred forty-four patients were analyzed. The median index dose was 0.7 mcg/kg (IQR, 0.3-2.0), and the mean increase in systolic blood pressure was 31 mmHg (95% CI, 25-36; P < 0.001). Thirty-nine (27%) patients were classified as non-responders. Compared to responders, non-responders had higher rates of cardiac arrest or extracorporeal membrane oxygenation within 6 h (26% vs 10%; relative risk, 2.69; 95% CI, 1.21-5.97; P = 0.03), and had higher in-hospital mortality (51% vs 21%; relative risk, 2.45; 95% CI, 1.51-3.96; P < 0.001)., Conclusions: In the majority of pre-arrest pediatric patients, bolus dilute epinephrine resulted in an increase in systolic blood pressure, and lack of blood pressure response was associated with poor outcomes. Optimal dosing of dilute epinephrine remains unclear., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Parents' emotional functioning represents a central mechanism in the caregiving environment's influence on adolescent affective brain function. However, a paucity of research has examined links between parental emotional arousal and regulation and adolescents' affective brain function. Thus, the present study examined associations between parents' self-rated negative emotion, parent emotion regulation difficulties, and adolescent brain responsivity to negative and positive emotional stimuli. Participants included 64 12-14 year-old adolescents (31 females) and their female primary caregivers. Adolescents viewed negative, positive, and neutral emotional stimuli during an fMRI scanning session. Region of interest analyses showed that higher parent negative emotion was related to adolescents' greater ACC and vmPFC response to both negatively- and positively-valenced emotional stimuli; whereas, parent negative emotion was related to adolescents' greater amygdala response to negative emotional stimuli only. Furthermore, parent emotion regulation moderated the association between parent negative emotion and adolescents' brain response to negative emotional stimuli, such that parents with high negative emotion and high emotion regulation difficulties had adolescents with the greatest affective brain response. Findings highlight the importance of considering both parent emotional arousal and regulation in understanding the family affective environment and its relation to adolescent emotion-related brain development.

Objectives: Pediatric early warning systems using expert-derived vital sign parameters demonstrate limited sensitivity and specificity in identifying deterioration. We hypothesized that modified tools using data-driven vital sign parameters would improve the performance of a validated tool., Design: Retrospective case control., Setting: Quaternary-care children's hospital., Patients: Hospitalized, noncritically ill patients less than 18 years old. Cases were defined as patients who experienced an emergent transfer to an ICU or out-of-ICU cardiac arrest. Controls were patients who never required intensive care. Cases and controls were split into training and testing groups., Interventions: The Bedside Pediatric Early Warning System was modified by integrating data-driven heart rate and respiratory rate parameters (modified Bedside Pediatric Early Warning System 1 and 2). Modified Bedside Pediatric Early Warning System 1 used the 10th and 90th percentiles as normal parameters, whereas modified Bedside Pediatric Early Warning System 2 used fifth and 95th percentiles., Measurements and Main Results: The training set consisted of 358 case events and 1,830 controls; the testing set had 331 case events and 1,215 controls. In the sensitivity analysis, 207 of the 331 testing set cases (62.5%) were predicted by the original tool versus 206 (62.2%; p = 0.54) with modified Bedside Pediatric Early Warning System 1 and 191 (57.7%; p < 0.001) with modified Bedside Pediatric Early Warning System 2. For specificity, 1,005 of the 1,215 testing set control patients (82.7%) were identified by original Bedside Pediatric Early Warning System versus 1,013 (83.1%; p = 0.54) with modified Bedside Pediatric Early Warning System 1 and 1,055 (86.8%; p < 0.001) with modified Bedside Pediatric Early Warning System 2. There was no net gain in sensitivity and specificity using either of the modified Bedside Pediatric Early Warning System tools., Conclusions: Integration of data-driven vital sign parameters into a validated pediatric early warning system did not significantly impact sensitivity or specificity, and all the tools showed lower than desired sensitivity and specificity at a single cutoff point. Future work is needed to develop an objective tool that can more accurately predict pediatric decompensation.

Education has a large and increasing impact on health in America. This paper examines one reason why. Education gives individuals the ability to override the default American lifestyle. The default lifestyle has three elements: displacing human energy with mechanical energy, displacing household food production with industrial food production, and displacing health maintenance with medical dependency. Too little physical activity and too much food produce imperceptibly accumulating pathologies. The medical industry looks for products and services that promise to soften the consequences but do not eliminate the underlying pathologies. This "secondary prevention" creates pharmacologic accumulation: prolonging the use of medications, layering them, and accruing their side effects and interactions. Staying healthy depends on recognizing the risks of the default lifestyle. Overriding it requires insight, knowledge, critical analysis, long-range strategic thinking, personal agency, and self-direction. Education develops that ability directly and indirectly, by way of creative work and a sense of controlling one's own life., (© American Sociological Association 2015.)

Objective: To estimate prenatal sexually transmitted disease-human immunodeficiency virus (HIV) screening rates among insured women with prenatal care and the association of chlamydia and gonorrhea screening with Pap testing., Methods: We estimated prenatal screening rates for syphilis, hepatitis B, HIV, chlamydia, and gonorrhea among women aged 15-44 years using a 2009-2010 U.S. administrative claims database that captures information for health services provided for both Medicaid- and commercially insured persons. Procedural and diagnostic codes were used to identify pregnant women with a live birth in 2010 with continuous insurance coverage at least 210 days before delivery and at least one typical prenatal blood test. Strengths of association between chlamydia and gonorrhea screening and Pap testing were measured using a χ test of independence., Results: Among 98,709 Medicaid-insured pregnant women, 95,064 (96.3%) were screened for syphilis, 95,082 (96.3%) for hepatitis B, 81,339 (82.4%) for HIV, 82,047 (83.1%) for chlamydia, and 73,799 (74.8%) for gonorrhea. Among 266,012 commercially insured women, 260,079 (97.8%) were screened for syphilis, 257,675 (96.8%) for hepatitis B, 227,276 (85.4%) for HIV, 187,071 (70.3%) for chlamydia, and 182,400 (68.6%) for gonorrhea. Prenatal screening for chlamydia and gonorrhea among both groups of women was more likely to be performed if a Pap test was also done (P<.001)., Conclusion: Prenatal screening for syphilis and hepatitis B was nearly universal among Medicaid- and commercially insured women; HIV screening rates were much lower and varied by insurance type and demographic characteristics. Chlamydia screening was suboptimal and most often occurred with Pap testing., Level of Evidence: III.

What is the association between food insufficiency and body weight? Although common sense would suggest a negative association, research often finds the opposite. We contrast commodity theories of material privation with stress theories, proposing that the seemingly counterintuitive association results from the confounding influence of economic hardship. Because it is a chronic stressor, economic hardship may contribute to overweight. Data from the WCF project of 2,402 disadvantaged women in Chicago, Boston, and San Antonio show that people who experience economic hardship weigh more; and that the true negative association between body weight and food insufficiency-especially going hungry because one cannot afford food-is revealed only after adjustment for economic hardship.

The positive associations between education and health and survival are well established, but whether the strength of these associations depends on gender is not. Is the beneficial influence of education on survival and on self-rated health conditioned by gender in the same way, in opposite ways, or not at all? Because women are otherwise disadvantaged in socioeconomic resources that are inputs to health, their health and survival may depend more on education than will men's. To test this hypothesis, we use data from the National Health Interview Survey-Linked Mortality Files (NHIS-LMF). We find that education's beneficial influence on feeling healthy and on survival are conditional on gender, but in opposite ways. Education has a larger effect on women's self-rated health than on men's, but a larger effect on men's mortality. To further examine the mortality results, we examine specific causes of death. We find that the conditional effect is largest for deaths from lung cancer, respiratory disease, stroke, homicide, suicide, and accidents. Because women report worse health but men's mortality is higher, education closes the gender gap in both health and mortality.

A threatening and dangerous neighborhood may produce distressing emotions of anxiety, anger, and depression among the individuals who live there because residents find these neighborhoods subjectively alienating. The author introduces the idea that neighborhood disorder indicates collective threat, which is alienating-shaping perceptions of powerlessness and mistrust. The author presents a theory of trust that posits that mistrust develops in places where resources are scarce and threat is common and among individuals with few resources and who feel powerless to avoid or manage the threat. Perceived powerlessness develops with exposure to uncontrollable, negative conditions such as crime, danger, and threat in one's neighborhood. Thus, neighborhood disorder, common in disadvantaged neighborhoods, influences mistrust directly and indirectly by increasing perceptions of powerlessness among residents, which amplify disorder's effect on mistrust. The very thing needed to protect disadvantaged residents from the negative effects of their environment-a sense of personal control-is eroded by that environment in a process that the author calls structural amplification. Powerlessness and mistrust in turn are distressing, increasing levels of anxiety, anger, and depression.

The association between education and good health is well established, but whether the strength of the association depends on other social statuses is not. We test a theory of resource substitution which predicts a larger correlation between education and health (measured for physical impairment) for people who grew up in families with poorly-educated parents than for those whose parents were well educated. This is supported in the Aging, Status, and Sense of control (ASOC) survey, a representative national U.S. sample with data collected in 1995, 1998, and 2001. The reason that parental education matters more to people who are poorly educated themselves is due to an unhealthy lifestyle, specifically to smoking and being overweight. Finally, as the poorly educated age, the negative health effects of their parents' low educational attainment get worse., (Copyright © 2010 Elsevier Ltd. All rights reserved.)

Does education improve health more for one sex than the other? We develop a theory of resource substitution which implies that education improves health more for women than men. Data from a 1995 survey of U.S. adults with follow-ups in 1998 and 2001 support the hypothesis. Physical impairment decreases more for women than for men as the level of education increases. The gender gap in impairment essentially disappears among people with a college degree. Latent growth SEM vectors also show that among the college educated, men's and women's life course patterns of physical impairment do not differ significantly.

Living in a threatening, noxious, and dangerous neighborhood may produce anxiety, anger, and depression because it is subjectively alienating. We hypothesize that neighborhood disorder represents ambient threat that elicits perceptions of powerlessness, normlessness, mistrust, and isolation. These perceptions in turn lead to anxious and angry agitation, and depressed exhaustion. We use data from the 1995 Community, Crime, and Health survey, a probability sample of 2,482 adults in Illinois, with a follow-up survey in 1998. We find that perceived neighborhood disorder is associated with high levels of anxiety, anger, and depression. Personal victimization mediates about 10 percent of the association. The rest of the association is mediated primarily by mistrust and, secondarily, by perceived powerlessness. Normlessness reflects neighborhood disorder but it appears to have little influence on distress. Social isolation has trade-offs in its connections to neighborhood disorder and to distress.

Objective: The goal of this research is to see if more highly educated older Chinese have lower levels of distress than do their poorly educated counterparts and whether engaging in cognitively stimulating activities such as reading and playing mahjong explains the association., Method: Using the Chinese Healthy Longevity Survey, the authors find a significant negative association between education and psychological distress. Much of the association is mediated by activities, but not all in the ways expected. Reading, playing mahjong, and watching television all negatively correlate with distress., Discussion: Better-educated older Chinese have lower levels of distress than do their less-well-educated counterparts in part because they engage in cognitively stimulating activities, have better economic circumstances, and engage in more physical activity.

Supplementation of epidural opioid analgesia with intravenous opioids is usually avoided because of concern about respiratory depression. However, the choice of adjunct analgesic agents for pediatric oncology patients is limited. Antipyretic drugs may mask fever in neutropenic patients, and nonsteroidal anti-inflammatory agents may exert antiplatelet effects and interact with chemotherapeutic agents. We examined the safety of concurrent use of epidural and intravenous opioids in a consecutive series of 117 epidural infusions in pediatric patients and compared our findings to those reported by other investigators. We observed a 0.85% rate of clinically significant respiratory complications. The single adverse event was associated with an error in dosage. In our experience, the supplementation of epidural opioid analgesia with intravenous opioids has been a safe method of postoperative pain control for pediatric patients with cancer.

Employees with greater control over their own activities have better health. People who are employed give up some control over their own activities for pay, yet employment is associated with better health. Perhaps paid jobs provide resources for productive self-expression that make up for the loss of autonomy. We find that paid employment is associated with lower autonomy but greater creativity of one's work or other main daily activities. Both have positive associations with health. Creativity's association is larger more statistically significant, and found in follow-up models as well as cross-sectional ones. The health advantage of being at the 60th versus the 40th percentile of creative work is equivalent to that of being 6.7 years younger or having two more years of education or 15 times greater household income. Education reduces the amount of autonomy lost in employment. Managerial authority and occupational attributes influence autonomy and creativity but otherwise have little or no association with health.

Does education improve psychological well-being more for one sex than for the other? Resource substitution theory hypothesizes that education improves well-being more for women, because socioeconomic disadvantage makes them depend more on education to achieve well-being. Resource multiplication implies the opposite, that education improves well-being more for men, because they get bigger labor market payoffs from it such as authority and earnings. Data from a 1995 survey of US adults with follow-ups in 1998 and 2001 support the resource substitution hypothesis. Depression decreases more steeply for women than for men as the level of education increases. The gender gap in depression essentially disappears among persons with a college degree or higher. Two mediating interactions appear to account for the convergence. Education increases work creativity more sharply for women than for men, thereby reducing depression. Education increases the sense of control for both sexes equally, but depression declines more steeply for women as sense of control increases. Growth curve analyses of depression vectors confirm the resource substitution pattern. The adulthood life course pattern of depression levels and changes depends more strongly on education for women than for men.

How do neighborhoods affect the health of residents? We propose that the impact of neighborhood disorder on self-reported health is mediated by psychological and physiological distress. We hypothesize a stress process in which chronic stressors in the environment give rise to a psychological and physiological stress response that ultimately affects health. The exogenous variable of interest is the neighborhood where disadvantaged persons live, which may expose them to chronic stressors in the form of crime, trouble, harassment, and other potentially distressing signs of disorder and decay. The mediator is the stress response that occurs in the body and brain. Of interest here is a psychological stress response in the form of fearful anxiety and depression, and a physiological stress response in the form of signs and symptoms of autonomic arousal, such as dizziness, chest pains, trouble breathing, nausea, upset stomach, and weakness. The outcome is poor health. This model is supported using data from the Welfare, Children, and Families project, a sample of 2,402 disadvantaged women in disadvantaged neighborhoods in Chicago, Boston, and San Antonio.
