AI-assisted systematic review on remediation of contaminated soils with PAHs and heavy metals.

This systematic review addresses soil contamination by crude oil, a pressing global environmental issue, by exploring effective treatment strategies for sites co-contaminated with heavy metals and polycyclic aromatic hydrocarbons (PAHs). Our study aims to answer pivotal research questions: (1) What are the interaction mechanisms between heavy metals and PAHs in contaminated soils, and how do these affect the efficacy of different remediation methods? (2) What are the challenges and limitations of combined remediation techniques for co-contaminated soils compared to single-treatment methods in terms of efficiency, stability, and specificity? (3) How do various factors influence the effectiveness of biological, chemical, and physical remediation methods, both individually and combined, in co-contaminated soils, and what role do specific agents play in the degradation, immobilization, or removal of heavy metals and PAHs under diverse environmental conditions? (4) Do AI-powered search tools offer a superior alternative to conventional search methodologies for executing an exhaustive systematic review? Utilizing big-data analytics and AI tools such as Litmaps.co, ResearchRabbit, and MAXQDA, this study conducts a thorough analysis of remediation techniques for soils co-contaminated with heavy metals and PAHs. It emphasizes the significance of cation-π interactions and soil composition in dictating the solubility and behavior of these pollutants. The study pays particular attention to the interplay between heavy metals and PAH solubility, as well as the impact of soil properties like clay type and organic matter on heavy metal adsorption, which results in nonlinear sorption patterns. The research identifies a growing trend towards employing combined remediation techniques, especially biological strategies like biostimulation-bioaugmentation, noting their effectiveness in laboratory settings, albeit with potentially higher costs in field applications. Plants such as Medicago sativa L. and Solanum nigrum L. are highlighted for their effectiveness in phytoremediation, working synergistically with beneficial microbes to decompose contaminants. Furthermore, the study illustrates that the incorporation of biochar and surfactants, along with chelating agents like EDTA, can significantly enhance treatment efficiency. However, the research acknowledges that varying environmental conditions necessitate site-specific adaptations in remediation strategies. Life Cycle Assessment (LCA) findings indicate that while high-energy methods like Steam Enhanced Extraction and Thermal Resistivity - ERH are effective, they also entail substantial environmental and financial costs. Conversely, Natural Attenuation, despite being a low-impact and cost-effective option, may require prolonged monitoring. The study advocates for an integrative approach to soil remediation, one that harmoniously balances environmental sustainability, cost-effectiveness, and the specific requirements of contaminated sites. It underscores the necessity of a holistic strategy that combines various remediation methods, tailored to meet both regulatory compliance and the long-term sustainability of decontamination efforts.

Worsening Symptoms of Anxiety, Depression, and Sleep Problems in Caregivers Following Youth's Suicide-Related Emergency Department Visit.

OBJECTIVE: Although families assume considerable responsibility in caring for their child after a suicidal crisis, little is known about caregiver well-being following a suicide-related pediatric Emergency Department (ED) visit. This study aimed to (1) describe the course of caregiver distress symptoms (e.g., anxiety, depression, and negative affect) and sleep problems following their child's suicide-related ED visit and to (2) identify factors (e.g., parents' mental health history, youth suicide risk chronicity, and perception of feeling supported by the mental health system) hypothesized to be related to caregiver distress symptoms and sleep problems at follow-up using a diathesis-stress model framework. METHOD: Participants included 118 caregiver/youth (ages 11-17) dyads presenting to a psychiatric ED due to youths' suicide-related concerns. Caregivers and youth were assessed during index ED visit and 2-weeks following discharge. RESULTS: Caregivers' anxiety and depressive symptoms and sleep problems increased significantly from the time of the ED visit to 2-week follow-up. There was no significant change in caregiver negative affect. Caregivers with their own history of mental illness and those whose children had a previous ED visit due to a psychiatric concern, suggestive of chronic suicide risk, reported higher anxiety and depressive symptoms at follow-up. CONCLUSION: In the 2 weeks following an ED visit for their child's suicidal crisis, caregivers reported significant increases in anxiety and depressive symptoms and sleep problems. Findings highlight the need to consider the mental health of caregivers whose children are at elevated risk for suicide.HighlightsCaregivers report increases in distress symptoms following youth's suicidal crisis.Caregiver mental health history and youth suicide chronicity impacted distress.Caregiver mental health should be considered when planning youth interventions.

Changes in Gatekeeper Beliefs Following ASIST and Relation to Subsequent Gatekeeper Suicide Prevention Behaviors.

This study examines relations between suicide prevention gatekeeper beliefs and actual helping behaviors following participation in Applied Suicide Intervention Skills Training (ASIST). Participants (n = 434) completed measures examining suicide-related beliefs and behaviors using a naturalistic pre-post design. All beliefs demonstrated significant change from pre- to posttest. Regression analyses indicate that beliefs about perceived barriers to action and the controllability of suicide predicted identification of high-risk youth; perceived barriers to action were also negatively related to helping responses and referrals 6-9 months post training. Self-efficacy was not related to suicide prevention behaviors at follow-up. The importance of anchoring training curriculums and measurement to health behavior change theories is discussed.

Predictors of Parent Behavioral Engagement in Youth Suicide Discharge Recommendations: Implications for Family-Centered Crisis Interventions.

The number of youth presenting to Emergency Departments (EDs) with psychiatric chief complaints has almost doubled in the last decade. With pediatric patients, ED brief interventions and discharge recommendations necessitate meaningful parental engagement to optimize youth safety and support. This study examined parent-level factors (stigmatizing attitudes, self-efficacy beliefs, distress symptoms, and illness-related stressors) in relation to parents' behavioral engagement (i.e., participation in and follow-through with best practice discharge recommendations). In this short-term prospective study, participants were 118 parent-youth (aged 11-18) dyads (57% female) recruited from a psychiatric ED. Parents' behavioral engagement was measured with parent- and youth-self report at 2-week follow-up. Parents' self-reported anxious and depressive symptoms, insomnia, stress, and stigmatizing attitudes were not related to engagement 2 weeks later. Higher parental self-efficacy beliefs were significantly associated with greater engagement in standard discharge recommendations. Implications for maximizing parent implementation of clinical recommendations during a youth suicide crisis are discussed.

Who drinks soda pop? Economic status and adult consumption of sugar-sweetened beverages.

We use two cohorts from the National Longitudinal Surveys (NLSY79 and NLSY97), which are large, nationally representative samples of U.S. adults, to investigate consumption of sugar-sweetened beverages (SSB) by SES, using nine surveys fielded between 2008 and 2016. Previous studies used income and education to measure SES, the NLS enables us to include wealth as well. Previous studies also used cross-sectional data, whereas the NLS allows us to examine whether changes in income and wealth correlate with changes in SSB intake. The results indicate an inverse gradient in SSB consumption with respect to both income and wealth, controlling for education. However, we do not find evidence that changes in income and wealth correlate with changes in SSB intake. This finding suggests that SES influences the development of SSB consumption patterns, but changes in income and wealth generally do not alter them in adulthood.

13 Reasons Why: Viewing Patterns and Perceived Impact Among Youths at Risk of Suicide.

OBJECTIVE: The streaming series 13 Reasons Why generated controversy because of its depiction of teen suicide and concerns about its impact on vulnerable youths. This study examined exposure to and patterns of engagement with the show and the show's perceived impact in a sample of youths presenting to a psychiatric emergency department (ED) with suicide-related concerns in the year after the series' premiere. METHODS: Participants were 87 parent-youth dyads (youths' mean±SD age=14.6±1.8; 71% of youths were female, 26% male, and 2% gender nonconforming) who completed a battery of questionnaires during their ED visit. RESULTS: Half (49%) of the sample viewed at least one episode of 13 Reasons Why, season 1. Most youths (84%) viewed the show alone and were more likely to discuss their reactions with peers (80%) than with a parent (34%). Over half of youth viewers (51%) believed the series increased their suicide risk to a nonzero degree; having a stronger identification with the lead female character was significantly related to this belief (r=.63, df=41, p<0.001). Youths with more depressive symptoms and suicidal ideation were more likely to identify with the lead characters and report negative affect while viewing. CONCLUSIONS: To date, this is the first published study examining viewing patterns and reactions to 13 Reasons Why in a high-risk sample. Although further research is needed, the findings suggest a particular vulnerability to the show's themes among youths at risk of suicide and the importance of prevention strategies to ameliorate risk among these viewers.

"Do I look fat?" Self-perceived body weight and labor market outcomes.

Research reporting that greater body weight is associated with lower wages and employment, particularly among women, focuses on how employers perceive workers. In contrast, we examine whether workers' own perceptions of body weight influence labor market outcomes. Numerous studies find that misperception of body weight influences health behaviors and health, both mental and physical. For example, anorexia nervosa involves the over-perception of weight and raises the risk of cardiovascular disease. Do the health consequences of inaccurate self-perceived weight carry through to the labor market? We use the National Longitudinal Survey of Youth 1997 (NLSY97) to investigate patterns in weight misperception and three labor market outcomes. We find little evidence that either over-perception or under-perception of weight is associated with wages, weeks worked, or the number of jobs held for women and men.

The association between socioeconomic status and adult fast-food consumption in the U.S.

Health follows a socioeconomic status (SES) gradient in developed countries, with disease prevalence falling as SES rises. This pattern is partially attributed to differences in nutritional intake, with the poor eating the least healthy diets. This paper examines whether there is an SES gradient in one specific aspect of nutrition: fast-food consumption. Fast food is generally high in calories and low in nutrients. We use data from the 2008, 2010, and 2012 waves of the National Longitudinal Survey of Youth (NLSY79) to test whether adult fast-food consumption in the United States falls as monetary resources rise (n=8136). This research uses more recent data than previous fast-food studies and includes a comprehensive measure of wealth in addition to income to measure SES. We find little evidence of a gradient in adult fast-food consumption with respect to wealth. While adults in the highest quintile are 54.5% less likely to report fast-food consumption than those in the lowest quintile, adults in the second and third quintiles are no less likely to report fast food-food intake than the poorest. Contrary to popular belief, fast-food consumption rises as income rises from the lowest to middle quintiles. The variation in adult fast-food consumption across income and wealth groups is, however, small. Those in the wealthiest quintile ate about one less fast-food meal on average than those in the lowest quintile. Other factors play a bigger role in explaining fast-food consumption: reading ingredient labels is negatively associated while soda consumption and hours of work are positively associated with fast-food consumption.

Identification, Response, and Referral of Suicidal Youth Following Applied Suicide Intervention Skills Training.

Gatekeeper training is a public health approach to suicide prevention that encourages community members to identify those at risk for suicide, respond appropriately, and refer for clinical services. Despite widespread use, few studies have examined whether training results in behavior change in participants. This study employed a naturalistic pre-post design to follow 434 participants in Applied Suicide Intervention Skills Training, finding small but significant increases in self-reported identification of at-risk youth, some helpful responses to youth, and numbers of youth referred to treatment from pre-test to 6- to 9-month follow-up. Changes in active listening and helping behaviors meant to support treatment referrals (such as convincing a youth to seek treatment) were not observed over time. Additional analyses explored predictors of self-reported skill utilization including identification as a "natural helper" and attitudes about suicide prevention.

Does the U.S. Food Stamp Program contribute to adult weight gain?

Obesity poses substantial costs both to the individual and society, mainly through its impact on health and labor productivity. Because obesity is more prevalent among the poor some have raised concerns that food assistance programs may encourage excess weight. This paper investigates whether the U.S. Food Stamp Program contributes to adult participants' weight as measured by body mass index (BMI). Results suggest that the typical female food stamp participant's BMI is indeed more than 1 unit higher than someone with the same socioeconomic characteristics who is not in the program. For the average American woman, who is 5 ft 4 in. (1.63 m) tall, this means an increase in weight of 5.8 pounds (2.6 kg). While this association does not prove that the Food Stamp Program causes weight gain, it does suggest that program changes to encourage the consumption of high-nutrient, low-calorie foods should be considered.

Behavioral, environmental, metabolic and intergenerational components of early life undernutrition leading to later obesity in developing nations and in minority groups in the U.S.A.

Nutritional transition, urbanization, and physical inactivity are primary factors responsible for the worldwide epidemic of overweight/obesity (OW/OB). However, these factors fail to explain the epidemic of OW/OB in developing countries and in recent-migrants to developed countries. Among these, OW/OB is associated with short/stunted stature and coexists with undernutrition at much higher rates than is statistically expected. Changes in metabolic pathways toward reduced fat oxidation and increased metabolism of carbohydrate may explain, in part, this phenomenon. Also, intergenerational consequences of malnutrition and poor health of the mothers may lead to impaired phenotypes in their offspring. We propose a novel methodology to assess the history of early life malnutrition by assessing the sitting height ratio of the mothers. The degree of "short leggedness" reflects undernutrition when the mother was an infant/child. Collectively, behavioral, environmental, metabolic and intergenerational components of early life undernutrition may provide a more satisfactory explanation for later life obesity.

A practical approach to public health surveillance of violent deaths related to intimate partner relationships.

OBJECTIVES: Articles describing the epidemiology of intimate partner homicide (IPH) have often been positioned as one-time research projects utilizing a single data source for case identification. However, researchers without access to centralized repositories for data pertinent to IPH can ascertain cases by using multiple extant data sources. The authors describe a surveillance system that can serve as a model for state health departments and others seeking to quantify and characterize violent deaths related to intimate partner relationships on an ongoing basis. METHODS: Retrospective surveillance was conducted to identify and characterize deaths related to intimate partnerships by linking the following data sources: death certificates, newspaper articles, law enforcement reports, and medical examiners' records. RESULTS: The authors identified at least 34% more IPHs using multiple data sources than would have been recognized solely using Supplementary Homicide Reports--the most frequently cited data source for IPH case ascertainment--and 22% more cases than newspaper data alone would have allowed for. CONCLUSIONS: While it was discovered that at least 181 IPHs--and at least 128 other deaths related to intimate partnerships--occurred in Michigan from 1999-2001, this frequency of occurrences is probably conservative. This limitation is due, in part, to the researchers not having access to information from all possible data source contributors. However, in the absence of statewide data systems, the authors demonstrate the utility of using multiple data sources for violent death surveillance to address incomplete case ascertainment.

Intimate partner violence against women: findings from one state's ED surveillance system.

INTRODUCTION: Victims of intimate partner violence against women (IPVAW) often come into contact with various health care professionals, including emergency nurses. Michigan has implemented an ED surveillance system to monitor IPVAW in the state. METHODS: Twenty-three emergency departments participate in the Michigan Intimate Partner Violence Surveillance System. Female assault and maltreatment victims are identified using International Classification of Diseases Clinical Modification (ICD-9-CM) diagnostic and E codes (External Cause of Injury/Adverse Effects codes). For a 2-year period (1999-2000), patients' charts were reviewed, usually by an emergency nurse, to identify IPVAW victims. RESULTS: A total of 3111 female assault and maltreatment victims were identified. Of the 2926 incidents for which physical and/or sexual violence was confirmed by chart review, 1136 (38.8% [95% confidence interval: 37.1% to 40.6%]) involved IPVAW. DISCUSSION: A hospital ED surveillance system revealed that more than a third of female assault and maltreatment incidents were attributable to intimate partner violence, with a considerable proportion being young women abused by an ex-boyfriend. Surveillance also identified a need for improved documentation of female assault and maltreatment in ED records. We realized the benefits of using a public health surveillance process to monitor IPVAW incidence, identify high-risk groups, and reduce research costs.

Are time preference and body mass index associated? Evidence from the National Longitudinal Survey of Youth.

The prevalence of obesity among both adults and children in the U.S. has risen to all time highs in the past two decades. We propose that an increase in the marginal rate of time preference has contributed to increasing obesity. More people are consuming more calories than they expend because they have become less willing to trade current pleasure for potential future health benefits. Accordingly, this paper explores the association between body mass index (BMI) and time preference. We use the National Longitudinal Survey of Youth (NLSY79) to test our hypothesis that time preference and BMI are positively related. We find some evidence that there is such a positive association among black and Hispanic men and black women.

Obesity and the rate of time preference: is there a connection?

It is hypothesized that recent trends in US and worldwide obesity are, in part, related to an increase in the marginal rate of time preference, where time preference refers to the rate at which people are willing to trade current benefit for future benefit. The higher the rate of time preference, the larger is the factor by which individuals discount the future health risks associated with current consumption. Data from the United States, as well as international evidence, suggest that a relationship between these two variables is plausible. The authors encourage researchers to explore the possible link between obesity and time preference, as important insights are likely to result.

An empowerment evaluation model for sexual assault programs: empirical evidence of effectiveness.

Using an empowerment evaluation approach, the Sexual Assault and Rape Prevention (SARP) Evaluation Project brought together university researchers, public health evaluators, state funders, and program staff to provide evaluation training and consultation to all state-funded rape prevention and victim services programs in Michigan. In this paper, the specific activities of the SARP project are described, and process and outcome data are presented that address the effectiveness of this empowerment evaluation approach. Based on subjective reports from program staff and objective data obtained from state funders, results suggest that this evaluation model was successful in helping 90% of the prevention programs and 75% of the victim services programs successfully develop and launch program evaluations. One-year follow-up data indicate that 90% of the programs had sustained their evaluation efforts after the formal work of the SARP project had ended.

Economic and anthropological assessments of the health of children in Maya immigrant families in the US.

Immigration from developing countries to the US generally increases access to health care and clean water, but it also introduces some unhealthy lifestyle patterns, such as diets dense in energy and little regular physical activity. We present a transdisciplinary model of child health and examine the impact of immigration on the physical growth and health of Maya children in Guatemala and the US. Maya-American children are much taller and have longer legs, on average, than their counterparts in Guatemala. This suggests that immigration to the US improves their health. However, the Maya-American children also are much heavier than both Guatemalan Maya and White American children, and have high rates of overweight and obesity. Quantile regression analysis indicates that Maya are shorter except in the upper tail of the stature distribution, and have higher Body Mass Index (BMI) in the tails, but not in the middle of the BMI distribution. Leisure time spent in front of a television or computer monitor tends to raise BMI in the middle and lower tail of the distribution, but not in the upper tail.
