Spanish translation of the Expert Recommendations for Implementing Change (ERIC) compilation.

BACKGROUND: Most implementation science resources (e.g., taxonomies) are published in English. Linguistic inaccessibility creates a barrier to the conduct of implementation research among non-English-speaking populations, so translation of resources is needed. Translation into Spanish can facilitate widespread reach, given the large proportion of Spanish speakers around the world. This research aimed to systematically translate the Expert Recommendations for Implementation Change (ERIC) compilation into Spanish as an exemplar for the linguistic translation process. METHODS: Using the World Health Organization guidelines, this work translated the ERIC compilation strategy names, short definitions, and thematic clusters through a three-step process: 1) forward translation into Spanish by a native Spanish-speaking implementation scientist, 2) back-translation into English by a bilingual global health researcher, and 3) piloting via virtual focus group discussions with bilingual researchers not conducting implementation research. To achieve a generalizable translation, recruitment targeted a multicultural group of Spanish-speaking researchers. At the conclusion of each step, the transdisciplinary research team (N = 7) met to discuss discrepancies and refine translations. The Spanish version of the ERIC compilation was finalized through group consensus. Reflections from research team meetings and focus group discussions were synthesized qualitatively. RESULTS: Given that dialectical nuances exist between Spanish-speaking regions, efforts prioritized universally accepted terminology. Team discussions focused on difficult translations, word choice, and clarity of concepts. Seven researchers participated in two focus groups, where discussion surrounded clarity of concepts, alternative word choice for Spanish translations, linguistic formality, grammar, and conciseness. Translation difficulties highlighted lack of precision in implementation science terminology, and the lack of conceptual clarity of words underscored limitations in the application of the compilation. CONCLUSIONS: The work demonstrated the feasibility of translating implementation science resources. As one of the first systematic efforts to translate implementation resources, this study can serve as a model for additional efforts, including translation into other languages and the expansion to conceptual modifications. Further, this work yielded insights into the need to provide conceptual clarity in implementation science terminology. Importantly, the development of Spanish resources will increase access to conduct implementation research among Spanish-speaking populations.

Family engagement in a behavioral parenting intervention: A randomized comparison of telehealth versus office-based treatment formats.

OBJECTIVE: Despite effective treatment options, many families-especially those from marginalized backgrounds-lack access to quality care for their children's behavioral difficulties. Since the COVID-19 pandemic, telehealth has become a prominent format for the delivery of outpatient services, with potential to increase access to quality care. Although telehealth-delivered parenting interventions are associated with positive clinical outcomes, limited research has examined whether telehealth formats improve treatment engagement relative to office-based care. The present study is the first controlled comparison of engagement across office-based parent-child interaction therapy (PCIT) and internet-delivered PCIT (iPCIT). METHOD: Children ages 3-5 years, and their caregiver(s) (N = 40) participated in a randomized trial comparing iPCIT to office-based PCIT in the treatment of behavioral problems. Analyses examined the effects of treatment format on engagement (i.e., missed sessions, premature treatment discontinuation, homework completion, therapeutic alliance, and treatment satisfaction). Logistic and linear regressions further explored whether treatment format moderated the effects of common predictors of treatment engagement (i.e., family economic means, racial/ethnic background, caregiver stress). RESULTS: iPCIT improved attendance rates relative to office-based PCIT, especially for families from minoritized racial/ethnic backgrounds. At the same time, among families with relatively higher levels of caregiver stress, office-based PCIT was associated with lower dropout rates and improved treatment alliance and satisfaction, relative to iPCIT. CONCLUSIONS: This study provides the first experimental support that telehealth formats can improve treatment attendance in behavioral parenting interventions. Findings highlight nuances in treatment engagement across treatment formats that reveal limits to the extent telehealth transcends engagement concerns.

Diabetes and the Microvasculature of the Bone and Marrow.

PURPOSE OF REVIEW: The purpose of this review is to highlight the evidence of microvascular dysfunction in bone and marrow and its relation to poor skeletal outcomes in diabetes mellitus. RECENT FINDINGS: Diabetes mellitus is characterized by chronic hyperglycemia, which may lead to microangiopathy and macroangiopathy. Micro- and macroangiopathy have been diagnosed in Type 1 and Type 2 diabetes, coinciding with osteopenia, osteoporosis, enhanced fracture risk and delayed fracture healing. Microangiopathy has been reported in the skeleton, correlating with reduced blood flow and perfusion, vasomotor dysfunction, microvascular rarefaction, reduced angiogenic capabilities, and augmented vascular permeability. Microangiopathy within the skeleton may be detrimental to bone and manifest as, among other clinical abnormalities, reduced mass, enhanced fracture risk, and delayed fracture healing. More investigations are required to elucidate the various mechanisms by which diabetic microvascular dysfunction impacts the skeleton.

To Proceed Via Telehealth or Not? Considerations for Pediatric Anxiety and Related Disorders Beyond COVID-19.

The COVID-19 pandemic accelerated a widespread shift to telehealth among mental health professionals to prioritize both providers' and clients' safety. Telehealth is likely here to stay; however, there is limited practical guidance for clinicians about how to make decisions regarding who should proceed with care via telehealth versus in-person. There also is virtually no data on the effectiveness of hybrid approaches to care; yet this can be an attractive option with potential clinical benefit. This paper provides practice-informed guidance to support shared clinical decision-making between clinicians and families to decide whether to engage in therapy services in-person or via telehealth. We specifically focus on decision-making guidance relevant for youth with anxiety or related disorders, given the unique implications of telehealth for these youth. Guided by the three-legged stool of evidence-based practice, we discuss how clinicians can use principles of shared decision-making to inform clinical recommendations about treatment modality.

Microplastic Presence in the Digestive Tract of Pearly Razorfish Xyrichtys novacula Causes Oxidative Stress in Liver Tissue.

Plastic pollution in the oceans is a growing problem, with negative effects on exposed species and ecosystems. Xyrichtys novacula L. is a very important fish species both culturally and economically in the Balearic Islands. The aim of the present study was to detect and categorise the presence of microplastics (MPs) in the digestive tract of X. novacula, as well as the existence of oxidative stress in the liver. For this purpose, the fish were categorised into two groups based on the number of MPs observed in the digestive tracts: a group with no or low presence of MPs (0-3 items) and a group with a higher presence of MPs (4-28 items). MPs were found in 89% of the specimens analysed, with a dominance of fibre type and blue colour. Regarding the type of polymer, polycarbonate was the most abundant, followed by polypropylene and polyethylene. For the group with a greater presence of MPs, the activities of the antioxidant enzymes glutathione peroxidase and glutathione reductase, as well as the phase II detoxification enzyme glutathione s-transferase, were higher than the activities observed in fish with little to no presence of MPs. The activities of catalase and superoxide dismutase and the levels of malondialdehyde did not show significant differences between both groups. In conclusion, these results demonstrate the presence of MPs in the digestive tract of X. novacula and the existence of an antioxidant and detoxification response, mainly based on the glutathione-based enzymes.

Power Redistribution and Upending White Supremacy in Implementation Research and Practice in Community Mental Health.

This Open Forum explores how implementation research and practice may sustain White supremacist ideas, perpetuate unequal power dynamics, and maintain mental health care inequities. The following questions were considered: What information is valued and considered evidence? and How do power differentials within implementation research and practice manifest? The implementation of evidence-based interventions within community mental health clinics is used as an example to explore these questions. Recommendations are provided to envision a future that centers collaboratively developed and community-led approaches to foster equity in mental health care.

Psychometric Evaluation of the Abbreviated Multidimensional Acculturation Scale (AMAS) in a Treatment-Seeking Sample of First-Generation Immigrant Caregivers.

The unique needs of first-generation immigrants and their families have not been prioritized in mental healthcare. Cultural tailoring of child services requires valid, reliable, and efficient assessments of family cultural identity. The Abbreviated Multidimension Acculturation Scale (AMAS) is a self-report of acculturation and enculturation that has been evaluated in community, but not clinical, samples. We offer the first AMAS psychometric evaluation in a treatment-seeking sample of first-generation immigrant caregivers presenting for children's mental healthcare (N = 219). Analyses examined the internal consistency, concurrent validity, and factor structures of the long-form AMAS (42 items, six subscales), AMAS-10 (10 items, four subscales), and AMAS-14 (14 items, six subscales). Findings provide support for the AMAS-10 and AMAS-14, but not the full-length AMAS, in the present sample. Given urgent needs for culturally responsive care for first-generation populations, the AMAS-10 and AMAS-14 can be used in clinical settings to support cultural assessment, case conceptualization, and treatment planning.

Preliminary Implementation Outcomes of a Free Online Toolkit to Support Exposure Therapy Implementation for Youth.

Background: Exposure therapy ("exposure") for youth anxiety is highly underutilized in clinical practice. Asynchronous, online implementation strategies such as online toolkits hold promise as pragmatic approaches for extending the sustainability of evidence-based interventions, but their long-term usage, perceived utility, and impact are rarely studied. Objective: This study presents three-year preliminary implementation outcomes for a free, online toolkit to support exposure therapy use with youth: the Resource for Exposure for Anxiety Disordered Youth (READY; www.bravepracticeforkids.com). Implementation outcomes of interest included READY usage statistics, adoption, perceived utility, and clinician exposure use. Methods: Web analytics characterized usage patterns. A survey of READY users (N = 49; M age = 34.2, 82.9% female, 71% White) assessed adoption, perceived utility, clinician exposure use, and persistent barriers to exposure use. Results: In its first three years, READY had 13,543 page views across 1,731 unique users; 442 (25.6%) registered as a site user to access specialized content. Survey data suggested variability in usage and perceived utility across toolkit components. Qualitative analyses highlighted persistent exposure barriers that pointed to potential READY refinements. Conculsions: Overall, READY has been accessed by hundreds of clinicians, but its impact was limited by low return to the site. This study highlights strengths and limitations of standalone online implementation supports and identifies additional steps needed to optimally support clinicians to deliver exposure to youth in need.

Telehealth Treatment of Behavior Problems in Young Children With Developmental Delay: A Randomized Clinical Trial.

Importance: Early behavior problems in children with developmental delay (DD) are prevalent and impairing, but service barriers persist. Controlled studies examining telehealth approaches are limited, particularly for children with DD. Objective: To evaluate the efficacy of a telehealth parenting intervention for behavior problems in young children with DD. Design, Setting, and Participants: A randomized clinical trial was conducted from March 17, 2016, to December 15, 2020, in which children with DD and externalizing behavior problems were recruited from early intervention and randomly assigned to a telehealth parenting intervention or control group and evaluated through a 12-month follow-up. Most children were from ethnic or racial minoritized backgrounds. Over one-half of children were in extreme poverty or low income-need ratio categories. Interventions: Internet-delivered parent-child interaction therapy (iPCIT), which leverages videoconferencing to provide live coaching of home-based caregiver-child interactions. Families received 20 weeks of iPCIT (provided in English or in Spanish) or referrals as usual (RAU). Main Outcomes and Measures: Observational and caregiver-report measures of child and caregiver behaviors and caregiving stress were examined at preintervention, midtreatment, and postintervention and at 6- and 12-month follow-ups. Results: The sample included a total of 150 children (mean [SD] age, 36.2 [1.0] months; 111 male children [74%]) and their caregivers with 75 each randomly assigned to iPCIT or RAU groups. Children receiving iPCIT relative to RAU displayed significantly lower levels of externalizing problems (postintervention Cohen d = 0.48; 6-month Cohen d = 0.49; 12-month Cohen d = 0.50) and significantly higher levels of compliance to caregiver direction after treatment. Of those children with data at postintervention, greater clinically significant change was observed at postintervention for children in the iPCIT group (50 [74%]) than for those in the RAU group (30 [42%]), which was maintained at the 6-month but not the 12-month follow-up. iPCIT did not outperform RAU in reducing caregiving stress, but caregivers receiving iPCIT, relative to RAU, showed steeper increases in proportion of observed positive parenting skills (postintervention odds ratio [OR], 1.10; 95% CI, 0.53-2.21; 6-month OR, 1.31; 95% CI, 0.61-2.55; 12-month OR, 1.64; 95% CI, 0.70-3.07) and sharper decreases in proportion of observed controlling/critical behaviors (postintervention OR, 1.40; 95% CI, 0.61-1.52; 6-month OR, 1.72; 95% CI, 0.58-1.46; 12-month OR, 2.23; 95% CI, 0.53-1.37). After treatment, iPCIT caregivers also self-reported steeper decreases in harsh and inconsistent discipline than did than RAU caregivers (postintervention Cohen d = 0.24; 6-month Cohen d = 0.26; 12-month Cohen d = 0.27). Conclusions and Relevance: Results of this randomized clinical trial provide evidence that a telehealth-delivered parenting intervention with real-time therapist coaching led to significant and maintained improvements for young children with DD and their caregivers. Findings underscore the promise of telehealth formats for expanding scope and reach of care for underserved families. Trial Registration: ClinicalTrials.gov Identifier: NCT03260816.

Identification, cloning, and characterization of a novel chitinase from leaf-cutting ant Atta sexdens: An enzyme with antifungal and insecticidal activity.

Chitinases are enzymes that degrade chitin, a polysaccharide found in the exoskeleton of insects, fungi, yeast, and internal structures of other vertebrates. Although chitinases isolated from bacteria, fungi and plants have been reported to have antifungal or insecticide activities, chitinases from insects with these activities have been seldomly reported. In this study, a leaf-cutting ant Atta sexdens DNA fragment containing 1623 base pairs was amplified and cloned into a vector to express the protein (AsChtII-C4B1) in Pichia pastoris. AsChtII-C4B1, which contains one catalytic domain and one carbohydrate-binding module (CBM), was secreted to the extracellular medium and purified by ammonium sulfate precipitation followed by nickel column chromatography. AsChtII-C4B1 showed maximum activity at pH 5.0 and 55 °C when tested against colloidal chitin substrate and maintained >60% of its maximal activity in different temperatures during 48 h. AsChtII-C4B1 decreased the survival of Spodoptera frugiperda larvae fed with an artificial diet that contained AsChtII-C4B1. Our results have indicated that AsChtII-C4B1 has a higher effect on larva-pupa than larva-larva molts. AsChtII-C4B1 activity targets more specifically the growth of filamentous fungus than yeast. This work describes, for the first time, the obtaining a recombinant chitinase from ants and the characterization of its insecticidal and antifungal activities.

Implementation mapping to plan for a hybrid trial testing the effectiveness and implementation of a behavioral intervention for HIV medication adherence and care retention.

Background: Implementation mapping is a systematic, collaborative, and contextually-attentive method for developing implementation strategies. As an exemplar, we applied this method to strategy development for Managed Problem Solving Plus (MAPS+), an adapted evidence-based intervention for HIV medication adherence and care retention that will be delivered by community health workers and tested in an upcoming trial. Methods: In Step 1: Conduct Needs Assessment, we interviewed 31 stakeholders to identify determinants of MAPS+ implementation in 13 clinics serving people with HIV in Philadelphia County. In Step 2: Develop Logic Model, we used these determinants as inputs for a working logic model guided by the Consolidated Framework for Implementation Research. In Step 3: Operationalize Implementation Strategies, our team held a virtual stakeholder meeting to confirm determinants. We synthesized stakeholder feedback, then identified implementation strategies that conceptually matched to determinants using the Expert Recommendations for Implementing Change taxonomy. Next, we operationalized implementation strategies with specific examples for clinic settings. We linked strategies to behavior change theories to allow for a mechanistic understanding. We then held a second virtual stakeholder meeting to present the implementation menu for feedback and glean generalizable insights for how these strategies could be operationalized in each stakeholder's clinic. In Step 4: Protocolize Strategies, we incorporated stakeholder feedback and finalized the implementation strategy menu. Findings: Implementation mapping produced a menu of 39 strategies including revise professional roles, identify and prepare champions, use warm handoffs, and change record systems. The process of implementation mapping generated key challenges for implementation strategy development: lack of implementation strategies targeting the outer setting (i.e., sociopolitical context); tension between a one-size-fits-all and individualized approach for all clinics; conceptual confusion between facilitators and strategies; and challenges in translating the implementation science lexicon for partners. Implications: This case exemplar advances both MAPS+ implementation and implementation science methods by furthering our understanding of the use of implementation mapping to develop strategies that enhance uptake of evidence-based interventions. The implementation menu will inform MAPS+ deployment across Philadelphia in an upcoming hybrid trial. We will carry out Step 5: Test Strategies to test the effectiveness and implementation of MAPS+.

Effects of Human Activity on Markers of Oxidative Stress in the Intestine of Holothuria tubulosa, with Special Reference to the Presence of Microplastics.

Pollution in the seas and oceans is a global problem, which highlights emerging pollutants and plastics, specifically microplastics (MPs), which are tiny (1 µm to 5 mm) ubiquitous plastic particles present in marine environments that can be ingested by a wide range of organisms. Holothurians are benthic organisms that feed on sediment; therefore, they can be exposed to contaminants present in the particles they ingest. The objective was to evaluate the effects of human activity on Holothuria tubulosa through the study of biomarkers. Specimens were collected in three different areas throughout the island of Eivissa, Spain: (1) a highly urbanized area, with tourist uses and a marina; (2) an urbanized area close to the mouth of a torrent; (3) an area devoid of human activity and considered clean. The results showed a higher presence of microplastics (MPs) in the sediments from the highly urbanized area in relation to the other two areas studied. Similarly, a higher number of MPs were observed in the digestive tract of H. tubulosa from the most affected area, decreasing with the degree of anthropic influence. Both in the sediment and in the holothurians, fibers predominated with more than 75% of the items. In the three areas, mesoplastics were analyzed by means of FTIR, showing that the main polymer was polypropylene (27%) followed by low-density polyethylene (17%) and polystyrene (16%). Regarding the biomarkers of oxidative stress, the intestine of H. tubulosa from the most impacted areas showed higher catalase, superoxide dismutase (SOD), glutathione reductase (GRd), and glutathione S-transferase (GST) activities and reduced glutathione (GSH) levels compared to the control area. The intermediate area only presented significant differences in GRd and GST with respect to the clean area. The activities of acetylcholinesterase and the levels and malondialdehyde presented similar values in all areas. In conclusion, human activity evaluated with the presence of MPs induced an antioxidant response in H. tubulosa, although without evidence of oxidative damage or neurotoxicity. H. tubulosa, due to its benthic animal characteristics and easy handling, can be a useful species for monitoring purposes.

Stakeholder Perspectives on MAPS.

BACKGROUND: Managed problem solving (MAPS) is an evidence-based intervention that can boost HIV medication adherence and increase viral suppression, but it is not widely used in community clinics. Deploying community health workers to deliver MAPS could facilitate broader implementation, in support of the Ending the HIV Epidemic (EHE) initiative's goal of reducing new HIV infections in the US by 90% by 2030. SETTING: Ryan White-funded clinics in Philadelphia, 1 of 48 US counties prioritized in the EHE. METHODS: Semistructured stakeholder interviews were conducted with 13 clinics and 4 stakeholder groups: prescribing clinicians, nonprescribing clinical team members (eg, medical case managers), clinic administrators, and policymakers. Interviews were based on the Consolidated Framework for Implementation Research and investigated perceived barriers to and facilitators of MAPS delivery by community health workers. Rapid qualitative analytic techniques were used to synthesize interview data and identify key categories along an implementation pathway. Core determinants (ie, barriers and facilitators) of MAPS implementation were grouped within each category. RESULTS: Stakeholders were receptive to CHW-delivered MAPS and offered critical information on potential implementation determinants including preferences for identification and referral of patients, and the importance of integration and communication within the care team. CONCLUSIONS: This study elucidates insights regarding barriers and facilitators to delivering an evidence-based behavioral intervention in clinics serving people with HIV (PWH) and extends a rapid qualitative approach to HIV care that rigorously incorporates stakeholder data into the development of implementation strategies. It also offers insights for national implementation efforts associated with EHE.

Microplastic presence in the pelagic fish, Seriola dumerili, from Balearic Islands (Western Mediterranean), and assessment of oxidative stress and detoxification biomarkers in liver.

Microplastics (MPs) are characterized by their high persistence in marine ecosystems, and due to their small size, they can be easily ingested by very diverse organisms. Although the presence of MPs in wild fish is well documented, there is still limited information on their potential to induce adverse effects. Pelagic fish species, because of their wide distribution, are considered good bioindicators for monitoring environmental pollution of marine ecosystems. This study investigated the presence of MPs in the gastrointestinal tract of the predatory pelagic fish (Seriola dumerili) in the Balearic Islands (Mediterranean Sea), and the possible relationship with oxidative stress through the analysis of biomarkers in liver tissue. The results showed the presence of MPs in 98% of total samples examined (n = 52) with an average of 12.2 ± 1.3 MPs/individual. A greater amount of fibre-like particles was isolated compared to fragments. No correlation between the presence of MPs in the gastrointestinal contents and the size of the fishes was noted. Antioxidant enzymes (superoxide dismutase and catalase) and the phase II detoxification enzyme glutathione-S-transferase showed increased activities in fish with higher MPs load. The activity ethoxyresorufin-O-deethylase and the levels of malondialdehyde were similar in both groups. In conclusion, the present results provide an important database on the assessment of the presence of MP debris in S. dumerili gastrointestinal tract and, the potential capability to cause oxidative stress.

First detection of microplastics in Xyrichtys novacula (Linnaeus 1758) digestive tract from Eivissa Island (Western Mediterranean).

Plastic waste and its ubiquity in the oceans represent a growing problem for marine life worldwide. Microplastics (MPs) are ubiquitous in the sea and easily enter food webs. Xyrichtys novacula L. is one of the main target species of recreational fishing in the Balearic Islands, Spain. In the present study, the quantity of MPs in gastrointestinal tracts of X. novacula from two different areas (a marine protected area (MPA) and a non-protected area) of Eivissa Island (in the Balearic archipelago) has been assessed, as well as MPs evaluation within the sediment of both areas. The results showed that over 80% of sampled individuals had MPs in their gut with an average of 3.9 ± 4.3 plastic items/individual. Eighty percent of these plastics were fibres, while the rest were fragments. Although the sediment of the non-protected area had a significant higher presence of MPs, no significant differences in the number of MPs were observed in X. novacula from both areas. The µ-FT-IR analysis showed that the main polymers in the sediments were polycarbonate (PC) and polypropylene (PP), whereas in the digestive tract of fish PC, PP, polyethylene, polystyrene and polyester. In conclusion, practically all X. novacula specimens presented MPs in their digestive tract regardless if the capture zone was in a MPAs or not. These results highlight the ubiquity of MPs in coastal marine areas, and further studies might be necessary to evaluate further implications of MP presence in this species.

Person-Centered Cultural Assessment Can Improve Child Mental Health Service Engagement and Outcomes.

OBJECTIVE: Disparities in child mental health service engagement suggest traditional evidence-based practices do not properly consider cultural and contextual factors relevant for marginalized families. We propose a person-centered approach to improve the cultural responsiveness of services. Preliminary research supports broadening standard assessments to include a person-centered evaluation of patient cultural factors, however, controlled studies have not been conducted in the context of children's mental health care. METHODS: Participants included families (N = 89; 89% racial/ethnic minority) receiving services for child externalizing problems. Prior to intake, caregivers were randomized to receive either Assessment as Usual (AAU) or AAU augmented with the Cultural Formulation Interview (CFI+AAU), a brief caregiver assessment of cultural factors affecting their child's problems and family help-seeking. RESULTS: Implementation data showed strong provider fidelity and clinical utility. Following assessments, CFI+AAU caregivers (relative to AAU caregivers) reported feeling better understood by their provider, and providers reported better understanding CFI+AAU families' values. Caregiver satisfaction was rated highly overall, yet providers reported being more satisfied with the assessment when the CFI was incorporated. Engagement outcomes found CFI+AAU families were significantly more likely than AAU families to subsequently complete the first phase of treatment. Further, among families receiving services in Spanish, CFI+AAU, relative to AAU, was associated with significantly higher treatment attendance, homework completion, and treatment response. CONCLUSIONS: The results underscore the utility of incorporating a brief cultural assessment in pretreatment assessments. To improve the cultural responsiveness of services, efforts may do well to promote the uptake of person-centered approaches such as cultural assessment into usual care.

Pelagic diatoms communicate through synchronized beacon natural fluorescence signaling.

Communication between conspecific individuals is an essential part of life both in terrestrial and marine realms. Until recently, social behavior in marine phytoplankton was assumed to rely mainly on the secretion of a variety of infochemicals that allowed population-scale collective responses. Here, we demonstrate that pelagic diatoms also use Sun-stimulated fluorescence signals for synchronizing their behavior. These unicellular microorganisms, playing a key biogeochemical role in the ocean, use photoreceptor proteins and red­far-red fluorescent radiation to communicate. A characteristic beaconing signal is generated by rhythmic organelle displacement within the cell cytoplasm, triggering coordinated population behavior. These light-based communication networks could critically determine major facets of diatom ecology and fitness and regulate the dynamics of larger-scale ocean processes.

Therapist-Led, Internet-Delivered Treatment for Early Child Social Anxiety: A Waitlist-Controlled Evaluation of the iCALM Telehealth Program.

Despite recent advances in the treatment of early child social anxiety, the broad accessibility of brick-and-mortar services has been limited by traditional barriers to care, and more recently by new obstacles related to efforts to slow the spread of COVID-19. The present waitlist-controlled trial examined the preliminary efficacy of a family-based behavioral parenting intervention (i.e., the iCALM Telehealth Program) that draws on Parent-Child Interaction Therapy and videoconferencing to remotely deliver clinician-led care for anxiety in early childhood. Young children (3-8 years) with a diagnosis of social anxiety disorder (N = 40; 65% from ethnic/racial minority backgrounds) were randomly assigned to iCALM or waitlist. Intent-to-treat analyses found that at post, independent evaluators classified roughly half of the iCALM-treated children, but only 6% of waitlist children, as "Responders" (Wald test = 4.51; p = .03). By Post, iCALM led to significantly greater reductions than waitlist in child anxiety symptoms, fear, discomfort, and anxiety-related social impairment, and also led to greater improvements in child soothability. By 6-month follow-up, the percentage of iCALM-treated children classified as "Responders" rose to roughly 60%. Exploratory moderation tests found iCALM was particularly effective in reducing life impairments and parental distress among families presenting with higher, relative to lower, levels of baseline parental accommodation. The present findings add to a growing body of research supporting the promise of technology-based strategies for broadening the portfolio of options for delivering clinician-led mental health services.

Caregiver stress and cultural identity in families of preschoolers with developmental delay and behavioral problems.

INTRODUCTION: Research on families of young children with developmental delay and disruptive behavior problems has failed to examine caregiver stress in the context of cultural factors. METHODS: Families of 3-year-old children with developmental delay and behavior problems were recruited from Early Intervention sites. All caregivers in the current analysis (n = 147) were from immigrant and/or cultural minority backgrounds. Regarding income-to-needs, most families (57.8%) fell into the extreme poverty, poor, or low-income categories. Caregivers reported on their own experiences of acculturation and enculturation as well as their child's problems. RESULTS: Path analyses revealed that higher caregiver acculturation was associated with less parenting-specific stress, and higher caregiver enculturation was associated with less caregiver general stress. Severity of child problems was associated with more parenting-specific stress and general stress. Exploratory analysis yielded significant differences in associations between acculturation, enculturation, and caregiver stress in Black/African American caregivers versus Hispanic White caregivers. CONCLUSION: Findings suggest that among cultural minority caregivers of young children with developmental and behavioral problems, acculturation and enculturation may influence caregiver stress. While the cross-sectional nature of the study precludes causal conclusions, clinicians should consider how cultural factors can be harnessed to strengthen caregiver resiliency and improve engagement in parenting interventions.

Cytochrome c: Using Biological Insight toward Engineering an Optimized Anticancer Biodrug.

The heme protein cytochrome c (Cyt c) plays pivotal roles in cellular life and death processes. In the respiratory chain of mitochondria, it serves as an electron transfer protein, contributing to the proliferation of healthy cells. In the cell cytoplasm, it activates intrinsic apoptosis to terminate damaged cells. Insight into these mechanisms and the associated physicochemical properties and biomolecular interactions of Cyt c informs on the anticancer therapeutic potential of the protein, especially in its ability to subvert the current limitations of small molecule-based chemotherapy. In this review, we explore the development of Cyt c as an anticancer drug by identifying cancer types that would be receptive to the cytotoxicity of the protein and factors that can be finetuned to enhance its apoptotic potency. To this end, some information is obtained by characterizing known drugs that operate, in part, by triggering Cyt c induced apoptosis. The application of different smart drug delivery systems is surveyed to highlight important features for maintaining Cyt c stability and activity and improving its specificity for cancer cells and high drug payload release while recognizing the continuing limitations. This work serves to elucidate on the optimization of the strategies to translate Cyt c to the clinical market.
