RESUMEN
Mangrove forests are threatened by the continuous discharge of inorganic pollutants and studies show that coasts receive high levels of heavy metals, from which lead (Pb) is one of the most persistent and toxic. In the present study, lead accumulation capacity, as well as its toxicological effects and tolerance mechanisms, such as proline accumulation and increased antioxidant capacity were evaluated in two contrasting mangrove species: Avicennia germinans and Laguncularia racemosa. Six-month-old plants were exposed to different concentrations of lead nitrate (0, 75, 150, and 300 µM) and samples of roots and leaves were taken from all treatments at different times during a 30d exposure period. Both species accumulated Pb in their tissues mainly in the roots, but L. racemosa had a greater capacity to accumulate Pb than A. germinans. Nevertheless, lead exposure caused less leaf chlorosis, lower reduction in the efficiency of photosystem II, lower reduction of daily photosynthetic rates, and lower electrolyte leakage in L. racemosa than in A. germinans. In line with those results, L. racemosa, in response to Pb exposure, accumulated more proline and showed higher antioxidant capacity than A. germinans, in both roots and leaves. Altogether, L. racemosa might be more suitable for restoration purposes, as it is not only capable of accumulating more Pb in its tissues but also shows greater tolerance to the stress caused by lead.

Copper (Cu) and zinc (Zn) have a high demand in the industry. However, these ions, at high concentrations, can cause severe damage to both fauna and flora. Phytoremediation has gained international importance because its relatively low cost and it is environmentally friendly. The aim of the present study was to evaluate the capacity of Salvinia minima of accumulating Cu and Zn from aqueous solutions of various external concentrations (20, 40 and 80 µmol L-1 of CuSO4 and ZnSO4, separately). In addition, to estimate the effect of exposure of S. minima plants to those metals, on various physiological parameters (growth potential, maximum quantum efficiency of PSII, electrolyte leakage: as a cell membrane integrity index). S. minima was able of accumulating more Zn than Cu in its tissues, reaching values of 6.96 mg Cu g-1 dry weight (DW) and 19.6 mg Zn g-1 DW when exposed to 80 µM of each metal during 96 h, that were stored mainly at roots. Despite accumulating less Cu in its tissues, Cu had more severe reductions in various physiological parameters than Zn (in maximum quantum efficiency, integrity of cell membranes, and growth). We conclude that this species can be useful in the phytoremediation for copper and zinc in relatively short time, as maximum accumulation occurred within the first 24 h. However, in the long term, the accumulation of such metals is accompanied by a negative impact in the appearance, physiology, and growth of this plant species, which was more severe for copper exposure than for zinc.

Pragmatic measures of therapist delivery of evidence-based practice (EBP) are critical to assessing the impact of large-scale, multiple EBP implementation efforts. As an initial step in the development of pragmatic measurement, the current study examined the concordance between therapist and observer ratings of items assessing delivery of EBP strategies considered essential for common child EBP targets. Possible EBP-, session-, and therapist-levels factors associated with concordance were also explored. Therapists and independent observers rated the extensiveness of therapist (n = 103) EBP strategy delivery in 680 community psychotherapy sessions in which six EBPs were used. Concordance between therapist- and observer-report of the extensiveness of therapist EBP strategy use was at least fair (ICC ≥ .40) for approximately half of the items. Greater therapist-observer concordance was observed in sessions where a structured EBP was delivered and in sessions where therapists reported being able to carry out planned activities. Findings highlighted conditions that may improve or hinder therapists' ability to report on their own EBP strategy delivery in a way that is consistent with independent observers. These results can help inform the development of pragmatic therapist-report measures of EBP strategy delivery and implementation efforts more broadly.

BACKGROUND: Brain-gut axis signaling modifies gastrointestinal symptomatology. Altered neural processing of intestinal pain signals involves interoceptive brain regions in adults with functional and inflammatory gastrointestinal disorders. Although these disorders frequently present in childhood, there are no published studies in youth. We determined whether neural processing of somatic pain stimuli differs in adolescents and young adults (AYA) with irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD), as compared to healthy controls (HC). METHODS: IBS and IBD AYA (16-20 years) underwent anticipated and thermal pain stimuli of low and high intensity on their forearm and simultaneous blood oxygen level-dependent functional magnetic resonance imaging. Data from adult HC were used for comparison. Subjects answered surveys evaluating alexithymia, anxiety, depression, and pain catastrophizing. Group data were compared using linear mixed effects and analysis of variance. RESULTS: Study groups were similar by sex but not age. Significant group by pain condition interactions were observed in interoceptive brain regions during pain anticipation, and within perceptual brain regions during perceived pain. Higher activation within interoceptive brain regions during anticipated pain was observed in IBS compared with IBD and HC subjects. IBD patients demonstrated increased activation in perceptual brain regions during experienced pain as compared to IBS and HC. CONCLUSIONS: IBS and IBD AYA demonstrate altered neural processing of somatic pain compared with each other and with HC. Our results suggest that neuromodulatory interventions targeting interoceptive brain circuits in IBS and perceptual brain regions in IBD may be effective.

OBJECTIVES: Informed consent (IC) is an essential communication between patient/representative and physician that acknowledges patient autonomy; assent is the equivalent process performed between youth and physician. For clinical procedures involving youth, only the IC process between guardian/parent and physician is required to be performed. Nevertheless, experts recommend that youth undergo assent whenever possible. In the present study, we explored both parental and youth understanding of required IC elements in IC discussions before pediatric endoscopy. METHODS: Following signing of IC documents on the day of endoscopy at a tertiary care academic medical center, youth and their parents underwent structured interviews to assess comprehension of key elements of the IC process. RESULTS: A total of 88 children and adolescents and their parents were evaluated. Two youth and 12 parents demonstrated comprehensive understanding of key IC elements for pediatric endoscopy. Suboptimal youth understanding was demonstrated for nature of the procedure (25% with adequate understanding) and related risks (17%), and alternatives (14%) to the procedure. Suboptimal parental understanding was demonstrated for procedure alternatives (24%). Youth overall understanding of IC varied by age, whereas parental global understanding of IC varied by physician. CONCLUSIONS: Understanding of IC performed for pediatric endoscopy could be improved in both parents and youth. Our findings suggest that interventions targeting parents, youth, and physicians may be helpful. Further study is needed to determine whether our findings are representative of IC understanding at other pediatric endoscopy centers.

BACKGROUND: Children surviving acute lymphoblastic leukemia (ALL) are at increased risk for overweight and obesity over that of the general population. Whether a generic or tailored approach to weight management is needed for cancer survivors has yet to be tested. PROCEDURE: Thirty-eight youth 8-18 years with BMI ≥ 85% who had survived ALL were recruited for a randomized clinical trial evaluating a weight management intervention (WMI) tailored for childhood ALL survivors (Fit4Life). Fit4Life recipients received a 4-month web, phone, and text message-delivered WMI tailored for cancer survivorship. Controls received a general WMI delivered via phone and mail. Assessments were performed at baseline and 4 months. Outcome data were analyzed according to assigned treatment condition over time. RESULTS: Most (80%, (70%, 100%) [median (IQR)]) of the assigned curriculum was received by Fit4Life participants as compared to 50% (40%, 65%) among controls. Fit4Life recipients ≥ 14 years demonstrated less weight gain (P = 0.05) and increased moderate-to-vigorous physical activity (P < 0.01) while all Fit4Life recipients reported reduced negative mood (P < 0.05) over time as compared to control counterparts. CONCLUSIONS: We demonstrated acceptable feasibility of a WMI tailored for overweight and obese children surviving ALL utilizing a multimodal technology approach. Improved weight, weight-related behavior, and psychological outcomes were demonstrated among Fit4Life intervention as compared to youth receiving a generic WMI. Data from this pilot trial may be used to design a larger trial to determine whether youth of all ages also can derive a benefit from a cancer survivor-tailored WMI and whether short-term outcomes translate into improved long-term outcomes for childhood ALL survivors.

OBJECTIVE: To assess the Health and Obesity: Prevention and Education (HOPE) Curriculum Project, a web-based clinician education program that promotes appropriate screening, prevention, and management of weight among youth by pediatric practitioners, based on the 2007 Expert Committee recommendations. The project currently provides Maintenance of Certification (MOC) Part 4 credit through the American Board of Pediatrics. STUDY DESIGN: Participants identified themselves to the HOPE MOC Part 4 program. Enrollees were required to complete all continuing medical education modules (10.5 hours). Knowledge acquisition and self-reported confidence levels related to screening, prevention, and management practices of pediatric obesity were measured using preknowledge and postknowledge questionnaires. Participants were also required to perform a quality improvement project and submit practice performance data from repeated medical chart reviews over time. Knowledge acquisition, self-efficacy, and practice performance data were analyzed using repeated-measures analyses. RESULTS: The 51 participants demonstrated significant improvements in knowledge acquisition and self-efficacy scores after viewing individual modules. In addition, participants demonstrated significant improvements in measured clinical compliance with recommended practices over time. CONCLUSIONS: Participation in the HOPE MOC Part 4 program appeared to improve knowledge acquisition, self-efficacy, and physician compliance with recommended practice recommendations for the screening, prevention, and management of pediatric obesity. Further data are required to determine whether such practice-based improvements translate into actual reduction in patient weight and/or reduction in health-related costs related to overweight and obesity in youth.

The study aims to determine SARS-CoV-2 RNA in sewage of Cancun wastewater treatment plants, the main touristic destination of Mexico, and to estimate the infected persons during the sampling period. SARS-CoV-2 RNA traces were detected in the inlet of the five plants during almost all the sampling months. However, there is no presence of SARS-CoV-2 RNA traces in the effluent of the five WWTPs during the study period. ANOVA analysis showed differences in the concentrations of RNA traces of SARS-CoV-2 between the sample dates, but no differences were found from one WWTP to another. Estimated infected individuals by Markov chain Monte Carlo simulation are higher (between 77% and 91%) than the cases reported by the health authority. Wastewater monitoring and the estimation of infected individuals are a helpful tool, because estimation provides early warning signs on how broadly SARS-CoV-2 is circulating in the city, and led to the authorities to take measures wisely. PRACTITIONER POINTS: There is no presence of SARS-CoV-2 RNA traces in the effluent of the facilities, suggesting the effectiveness of treatment. Surveillance of viral RNA concentrations at treatment plants revealed presence in the influent of five plants Estimated infected individuals by MCMC simulation are higher than cases reported by health authority Environmental surveillance approach in wastewater influent is helpful to identify the clusters and to take informed decisions.

Despite substantial support for the importance of routine progress monitoring (RPM) as part of evidence-based practice, few providers utilize measurement-based care. This study sought to identify the relative importance of facilitation strategies viewed as most helpful for increasing intention to use RPM among 388 ethnically diverse community therapists serving children and families. Four types of facilitation strategies were examined: language/interpretability, automation, staffing/access, and requirements. Mixed analyses of variance found that therapists' reported intentions to use RPM were more influenced by strategies of automating assessment administration, provision of clerical assistance, and agency requirements than by making linguistically appropriate measures available. However, the importance of strategies differed depending on therapist race/ethnicity and current RPM use. Language/interpretability of RPM assessments was less emphasized for non-Hispanic White therapists and therapists who have not yet or only minimally adopted RPM compared with ethnic minority therapists and therapists who regularly use RPM, respectively. Furthermore, therapists who were not current RPM users emphasized automation more than staffing/access. Results may inform prioritization of implementation facilitation strategies for agencies to encourage RPM. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Community mental health services are increasingly embracing evidence-based interventions (EBIs), and the professional workforce is diversifying to meet the needs of historically underserved groups. As such, it is increasingly important to understand how psychotherapist cultural factors may be associated with attitudes toward EBIs. The use of standardized assessments within routine progress monitoring is a cornerstone of EBIs, yet therapist attitudes remain an obstacle to implementation. The current study examines the associations between therapist cultural identity and attitudes toward and use of routine progress monitoring. An online survey was used to gather data from 229 ethnic minority community therapists delivering EBIs in a large public mental health system serving children and families. Therapists had an average age of 35.2 years (SD = 7.7), 86.5% were female, 69.9% were Hispanic/Latinx and 30.2% were other ethnic minority, 36.2% were licensed, 90.8% held a master's degree, and 76.4% reported ability to deliver services in a non-English language. Hierarchical multiple regression analyses revealed that stronger heritage cultural identity was related to perceptions of potential harm with routine progress monitoring. In addition, more favorable views of standardized assessment instructions were associated with positive attitudes toward routine progress monitoring. We discuss how findings point to the need for additional user-centered research with diverse community therapists to learn how assessment and progress monitoring can be better designed to address their cultural and racial-based concerns.

Background and study aims Youth undergoing pediatric endoscopic procedures and their parents demonstrate suboptimal comprehension of the informed consent (IC) process. We developed informational videos discussing key IC elements for pediatric endoscopy and evaluated their effects on youth and parental comprehension of the IC process. Patients and methods A randomized controlled trial of the video intervention was performed among youth undergoing endoscopy and their parents at an academic children's hospital. Randomization occurred at the time of enrollment using permutated blocks. Following the IC process with the proceduralist, subjects underwent structured interviews to assess IC comprehension. An Informed Consent Overall Score (ICOS: range 0â-â4) for comprehension was calculated. Results Seventy-seven pairs of children and their parents participated. Intervention recipients (Nâ=â37 pairs) demonstrated higher ICOS scores as compared to control counterparts (mean (standard deviation): 3.6 (0.7) v. 2.9 (0.9), intervention v. control parents, Pâ<â0.0001 and 2.7 (1.1) v. 1.7 (1.1), intervention v. control youth, Pâ<â0.0001). Conclusions A media intervention addressing key elements of the IC process for pediatric endoscopy was effective in improving comprehension of IC for youth undergoing endoscopic procedures and their parents.
RESUMEN
BACKGROUND AND AIMS: US hospitals routinely provide food to hospitalized children. The nutritional content of provided foods has not been evaluated. We performed our study to examine meal orders of hospitalized youth and determine whether the nutritional contents of ordered meals meet dietary guidelines. METHODS: We performed a cross-sectional evaluation among hospitalized youth ≥1 y receiving all nutritional intake by mouth and not on a clear liquid diet. Meal orders from hospitalized youth were analyzed for nutritional content. Daily calories, fiber, protein, fat content, and sugar-sweetened beverages ordered were determined and compared with published dietary recommendations. Distribution analyses and odds ratios for meeting v. not meeting dietary recommendations were calculated for select factors and adjusted for hospital length of stay. RESULTS: 969 meal orders from 247 patients [13 (1, 26) [median (min, max)] years, 50% male, 47% Hispanic] at a tertiary care pediatric hospital were reviewed. Forty-four percent of daily meals exceeded caloric recommendations, 9% met fiber recommendations, 36% met fat recommendations, all met protein requirements, and 53% included sugar-sweetened beverages. Overweight/obese boys <13 y hospitalized ≤7 d were more likely to place meal orders exceeding daily caloric recommendations while Hispanic overweight/obese youth hospitalized ≤7 d were more likely to order sugar-sweetened beverages than inpatient counterparts. CONCLUSIONS: Pediatric hospital meal orders commonly do not meet dietary guidelines. Hospitals should encourage youth and families to order within nutritional guidelines to prevent additional health risk.

Ocean acidification is a pervasive threat to coral reef ecosystems, and our understanding of the ecological processes driving patterns in tropical benthic community development in conditions of acidification is limited. We deployed limestone recruitment tiles in low aragonite saturation (Ωarag) waters during an in-situ field experiment at Puerto Morelos, Mexico, and compared them to tiles placed in control zones over a 14-month investigation. The early stages of succession showed relatively little difference in coverage of calcifying organisms between the low Ωarag and control zones. However, after 14 months of development, tiles from the low Ωarag zones had up to 70% less cover of calcifying organisms coincident with 42% more fleshy algae than the controls. The percent cover of biofilm and turf algae was also significantly greater in the low Ωarag zones, while the number of key grazing taxa remained constant. We hypothesize that fleshy algae have a competitive edge over the primary calcified space holders, coralline algae, and that acidification leads to altered competitive dynamics between various taxa. We suggest that as acidification impacts reefs in the future, there will be a shift in community assemblages away from upright and crustose coralline algae toward more fleshy algae and turf, established in the early stages of succession.

BACKGROUND: Adolescents with chronic disease (ACD) must develop independent disease self-management and learn to communicate effectively with their health care team to transition from pediatric to adult-oriented health care systems. Disease-specific interventions have been implemented to aid specific ACD groups through transition. A generic approach might be effective and cost-saving. METHODS: Eighty-one ACD, aged 12 to 20 years, were recruited for a randomized clinical trial evaluating an 8-month transition intervention (MD2Me). MD2Me recipients received a 2-month intensive Web-based and text-delivered disease management and skill-based intervention followed by a 6-month review period. MD2Me recipients also had access to a texting algorithm for disease assessment and health care team contact. The intervention was applicable to adolescents with diverse chronic illnesses. Controls received mailed materials on general health topics. Disease management, health-related self-efficacy, and health assessments were performed at baseline and at 2 and 8 months. Frequency of patient-initiated communications was recorded over the study period. Outcomes were analyzed according to assigned treatment group over time. RESULTS: MD2Me recipients demonstrated significant improvements in performance of disease management tasks, health-related self-efficacy, and patient-initiated communications compared with controls. CONCLUSIONS: Outcomes in ACD improved significantly among recipients of a generic, technology-based intervention. Technology can deliver transition interventions to adolescents with diverse chronic illnesses, and a generic approach offers a cost-effective means of positively influencing transition outcomes. Further research is needed to determine whether improved short-term outcomes translate into an improved transition for ACD.
