Exploring Adaptation and Fidelity in Parenting Program Implementation: Implications for Practice With Families

The vast majority of evidence-based programs (EBPs) for parenting are manualized and, as evaluated in research settings, have been implemented with a high degree of fidelity. In the real world, providers make changes to evidence-based programs they deliver, including combining programs and modifying materials to meet client needs. Additional research on adaptation of EBPs delivered in natural settings is needed to understand the nature of and reasons for adaptation in program delivery. Moore, Bumbarger, & Cooper (2013) proposed a taxonomy for categorizing adaptations based on fit, timing, and valence. In order to examine the utility of this taxonomy, a qualitative study was conducted with parenting education practitioners to better understand the adaptation options and motivations facing practitioners. Semi-structured interviews were conducted with program coordinators from three community providers in a Southeastern U.S. state. Interviews were followed by an in-person focus groups with program coordinators and participants. Questions were adapted from Moore et al. to explore fit, timing, and valence. A new dimension, autonomy, was added to explore the degree to which the provider can freely make changes to the program or is constrained by external ecological influences. Qualitative responses were coded by two members of the research team across the four domains. Internal validity was assessed by a third team member coding a sample of the team’s coding for comparison. Implications for use of the Moore et al. taxonomy in natural settings are discussed, including implications for community providers in multicultural settings and who are facing real-world external pressures

School Mental Health Early Interventions and Academic Outcomes for At-risk High School Students: A Review of the Research

The current educational policy context in the United States necessitates that school-based programs prioritize students’ academic outcomes. This review examined the quantitative research on school mental health (SMH) early interventions and academic outcomes for at risk high school students. Seven articles met the inclusion criteria for this review. All articles were examined according to study design and demographics, early intervention characteristics, and outcomes. Of the studies included, most were conducted in urban settings, involved the implementation of group-based early intervention strategies, and monitored GPA as a distal academic outcome. Counselors were frequent implementers of these early interventions. A meta-analysis found no statistically significant effect on the academic outcomes most commonly assessed in the studies (i.e., GPA, attendance, and discipline). Findings suggest the need for more rigorous research in this area. Implications for SMH early intervention research and practice are discussed

The diversity and evolution of pollination systems in large plant clades: Apocynaceae as a case study

Background and Aims Large clades of angiosperms are often characterized by diverse interactions with pollinators, but how these pollination systems are structured phylogenetically and biogeographically is still uncertain for most families. Apocynaceae is a clade of >5300 species with a worldwide distribution. A database representing >10 % of species in the family was used to explore the diversity of pollinators and evolutionary shifts in pollination systems across major clades and regions. Methods The database was compiled from published and unpublished reports. Plants were categorized into broad pollination systems and then subdivided to include bimodal systems. These were mapped against the five major divisions of the family, and against the smaller clades. Finally, pollination systems were mapped onto a phylogenetic reconstruction that included those species for which sequence data are available, and transition rates between pollination systems were calculated. Key Results Most Apocynaceae are insect pollinated with few records of bird pollination. Almost three-quarters of species are pollinated by a single higher taxon (e.g. flies or moths); 7 % have bimodal pollination systems, whilst the remaining approx. 20 % are insect generalists. The less phenotypically specialized flowers of the Rauvolfioids are pollinated by a more restricted set of pollinators than are more complex flowers within the Apocynoids + Periplocoideae + Secamonoideae + Asclepiadoideae (APSA) clade. Certain combinations of bimodal pollination systems are more common than others. Some pollination systems are missing from particular regions, whilst others are over-represented. Conclusions Within Apocynaceae, interactions with pollinators are highly structured both phylogenetically and biogeographically. Variation in transition rates between pollination systems suggest constraints on their evolution, whereas regional differences point to environmental effects such as filtering of certain pollinators from habitats. This is the most extensive analysis of its type so far attempted and gives important insights into the diversity and evolution of pollination systems in large clades

Genomic monitoring of SARS-CoV-2 variants using sentinel SARI hospital surveillance.

To support the COVID-19 pandemic response, many countries, including Belgium, implemented baseline genomic surveillance (BGS) programs aiming to early detect and characterize new SARS-CoV-2 variants. In parallel, Belgium maintained a sentinel network of six hospitals that samples patients with severe acute respiratory infections (SARI) and integrated SARS-CoV-2 detection within a broader range of respiratory pathogens. We evaluate the ability of the SARI surveillance to monitor general trends and early signals of viral genetic evolution of SARS-CoV-2 and compare it with the BGS as a reference model. Nine-hundred twenty-five SARS-CoV-2 positive samples from patients fulfilling the Belgian SARI definition between January 2020 and December 2022 were sequenced using the ARTIC Network amplicon tiling approach on a MinION platform. Weekly variant of concern (VOC) proportions and types were compared to those that were circulating between 2021 and 2022, using 96,251 sequences of the BGS. SARI surveillance allowed timely detection of the Omicron (BA.1, BA.2, BA.4, and BA.5) and Delta (B.1.617.2) VOCs, with no to 2 weeks delay according to the start of their epidemic growth in the Belgian population. First detection of VOCs B.1.351 and P.1 took longer, but these remained minor in Belgium. Omicron BA.3 was never detected in SARI surveillance. Timeliness could not be evaluated for B.1.1.7, being already major at the start of the study period. Genomic surveillance of SARS-CoV-2 using SARI sentinel surveillance has proven to accurately reflect VOCs detected in the population and provides a cost-effective solution for long-term genomic monitoring of circulating respiratory viruses

Nationwide Harmonization Effort for Semi-Quantitative Reporting of SARS-CoV-2 PCR Test Results in Belgium.

From early 2020, a high demand for SARS-CoV-2 tests was driven by several testing indications, including asymptomatic cases, resulting in the massive roll-out of PCR assays to combat the pandemic. Considering the dynamic of viral shedding during the course of infection, the demand to report cycle threshold (Ct) values rapidly emerged. As Ct values can be affected by a number of factors, we considered that harmonization of semi-quantitative PCR results across laboratories would avoid potential divergent interpretations, particularly in the absence of clinical or serological information. A proposal to harmonize reporting of test results was drafted by the National Reference Centre (NRC) UZ/KU Leuven, distinguishing four categories of positivity based on RNA copies/mL. Pre-quantified control material was shipped to 124 laboratories with instructions to setup a standard curve to define thresholds per assay. For each assay, the mean Ct value and corresponding standard deviation was calculated per target gene, for the three concentrations (10, 10 and 10 copies/mL) that determine the classification. The results of 17 assays are summarized. This harmonization effort allowed to ensure that all Belgian laboratories would report positive PCR results in the same semi-quantitative manner to clinicians and to the national database which feeds contact tracing interventions
