Using low-coverage whole genome sequencing (genome skimming) to delineate three introgressed species of buffalofish (Ictiobus).

Consumption of buffalofish has been sporadically associated with Haff disease-like illnesses involving sudden onset muscle pain and weakness due to skeletal muscle rhabdomyolysis, but determination of precisely which species are associated with these illnesses has been impeded by a lack of species-specific DNA-based markers. Here, three closely related species of buffalofish native to the Mississippi River Basin (Ictiobus bubalus, Ictiobus cyprinellus and Ictiobus niger) that have previously proven genetically indistinguishable using both mitochondrial and nuclear single-locus sequencing were reliably discriminated using low-coverage whole genome sequencing ('genome skimming'). Using 44 specimens representing the three species collected from the mid/upper (Missouri) and lower (Louisiana) regions of the species' native ranges, the SISRS (Site Identification from Short Read Sequences) bioinformatics pipeline was adapted to (1) identify over 620Mbp of putatively homologous nuclear sequence data and (2) isolate over 140,000 single-nucleotide polymorphisms (SNPs) that supported accurate species delimitation, all without the use of a reference genome or annotation data. These sites were used to classify Ictiobus spp. samples with genome-skim data, along with a larger set (n = 67) where ultraconserved elements (UCEs) were sequenced. Analyses of whole mitochondrial data revealed more limited signal. Nearly all samples matched their purported species based on morphologic identification, but two Missouri samples morphologically identified as I. niger grouped with samples of I. bubalus, albeit with significant enrichment of I. niger SNPs. To our knowledge this is the first report of a DNA-based tool to reliably discriminate these three morphologically distinct species.

A big data-model integration approach for predicting epizootics and population recovery in a keystone species.

Infectious diseases pose a significant threat to global health and biodiversity. Yet, predicting the spatiotemporal dynamics of wildlife epizootics remains challenging. Disease outbreaks result from complex nonlinear interactions among a large collection of variables that rarely adhere to the assumptions of parametric regression modeling. We adopted a nonparametric machine learning approach to model wildlife epizootics and population recovery, using the disease system of colonial black-tailed prairie dogs (BTPD, Cynomys ludovicianus) and sylvatic plague as an example. We synthesized colony data between 2001 and 2020 from eight USDA Forest Service National Grasslands across the range of BTPDs in central North America. We then modeled extinctions due to plague and colony recovery of BTPDs in relation to complex interactions among climate, topoedaphic variables, colony characteristics, and disease history. Extinctions due to plague occurred more frequently when BTPD colonies were spatially clustered, in closer proximity to colonies decimated by plague during the previous year, following cooler than average temperatures the previous summer, and when wetter winter/springs were preceded by drier summers/falls. Rigorous cross-validations and spatial predictions indicated that our final models predicted plague outbreaks and colony recovery in BTPD with high accuracy (e.g., AUC generally >0.80). Thus, these spatially explicit models can reliably predict the spatial and temporal dynamics of wildlife epizootics and subsequent population recovery in a highly complex host-pathogen system. Our models can be used to support strategic management planning (e.g., plague mitigation) to optimize benefits of this keystone species to associated wildlife communities and ecosystem functioning. This optimization can reduce conflicts among different landowners and resource managers, as well as economic losses to the ranching industry. More broadly, our big data-model integration approach provides a general framework for spatially explicit forecasting of disease-induced population fluctuations for use in natural resource management decision-making.

Barriers to and Strategies for Dietary Adherence: A Qualitative Study Among Hemodialysis/Peritoneal Dialysis Patients and Health Care Providers.

OBJECTIVES: The objectives of this study were: (1) investigate hemodialysis (HD)/peritoneal dialysis (PD) patients' barriers to dietary adherence, (2) identify strategies to overcome these barriers, and (3) examine dialysis providers' perceptions toward patients' barriers to dietary adherence and strategies to overcome these barriers. METHODS: A qualitative descriptive approach was conducted from February-May 2022. A total of 21 HD/PD participants and 11 health care providers participated in individual interviews. HD/PD participants also responded to a 57-item food frequency questionnaire. Six months of serum laboratory values were obtained from the medical charts. Content analysis methodology was used to identify themes. Mann-Whitney U tests were conducted to examine diet quality and laboratory values of the HD and PD participants using SPSS v.27 with statistical significance of P < .05. RESULTS: The median (interquartile range) diet quality score for HD/PD patients was 36 (26-43) with no differences observed between the patient populations. Mann-Whitney U tests showed no differences between serum laboratory values between the patient populations. Barriers identified by the HD/PD patients were communication/patient education and dietary habits. Barriers identified by the health care providers were communication/patient education and socioeconomic status. Strategies to overcome these barriers were enhancing communication between all parties involved in the care and tailoring educational information to the patient's background. CONCLUSIONS: Communication and patient education were themes identified among both health care providers and patients. Therefore, open communication among the patients and providers and enhancement of the nutrition education handouts may improve dietary adherence.

Interventions Within the Scope of Occupational Therapy to Address Preventable Adverse Events in Inpatient and Home Health Postacute Care Settings: A Systematic Review.

IMPORTANCE: Practitioners need to be familiar with, and involved in, managing quality-related adverse events in postacute care. OBJECTIVE: To determine interventions within the scope of occupational therapy that address preventable adverse events in adult postacute inpatient and home health settings. DATA SOURCES: Articles published from January 1995 through 2019 identified through searches of MEDLINE, PsycINFO, CINAHL, OTseeker, and Cochrane databases. Study Selection and Data Collection: Articles were collected, evaluated, and analyzed by two independent reviewers. They were assessed and synthesized with a goal of informing clinical practice. FINDINGS: Twenty-four articles were included in the review. Of the 10 Centers for Medicare & Medicaid Services preventable adverse events, 6 were addressed: diabetes management (n = 2), dysphagia (n = 5), infection control (n = 1), pressure ulcers (n = 6), falls (n = 5), and discharge management (n = 5). There was strong strength of evidence that exercise programs should, when appropriate, be implemented in both inpatient and home health settings to decrease the risk of falls. There was moderate strength of evidence that practitioners could consider implementing a facility wide evidence-based pressure ulcer program; providing multidisciplinary rehabilitation and swallow strengthening exercises for dysphagia; implementing a multidisciplinary, multicomponent falls program; and using a manualized depression intervention in home health to decrease hospital readmission. CONCLUSIONS AND RELEVANCE: The review highlights the importance of preventable adverse events and of occupational therapy practitioners acknowledging and managing these events to enhance health outcomes and to control health care costs. What This Article Adds: Many interventions typically performed by occupational therapy practitioners address preventable adverse events. The review highlights the importance of practitioners being aware of this category of impairment or injury.

Interventions to Improve Social Participation, Work, and Leisure Among Adults Poststroke: A Systematic Review.

IMPORTANCE: Sustaining a stroke frequently leads to difficulties in returning to work, leisure, and social participation. These outcomes are important for occupational therapy practitioners to address. OBJECTIVE: To determine the current evidence for the effectiveness of interventions within the scope of occupational therapy practice to improve social participation, work, and leisure among adults poststroke. DATA SOURCES: MEDLINE, PsycINFO, CINAHL, OTseeker, and Cochrane databases. STUDY SELECTION AND DATA COLLECTION: Primary inclusion criteria were peer-reviewed journal articles published between January 1, 2009, and December 31, 2019, within the scope of occupational therapy that evaluated an intervention to address work, leisure, or social participation poststroke (levels of evidence ranged from Level 1b to Level 2b). Reviewers assessed records for inclusion, quality, and validity following Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. FINDINGS: Forty-seven articles met the inclusion criteria. Forty-four articles related to social participation were categorized as follows: occupation-based approaches, metacognitive strategy training, education and training approaches, impairment-based approaches, and enriched environment approaches. Three articles related to work and 3 articles related to leisure were not further categorized (2 articles were each included in two categories). Seventeen Level 1b and 30 Level 2b articles were included. The strength of evidence to support occupational therapy interventions for social participation, work, and leisure outcomes is predominantly low. CONCLUSIONS AND RELEVANCE: Occupational therapy interventions may improve work, leisure, and social participation outcomes poststroke, with the strongest evidence existing for client education, upper extremity training, and cognitive training for improving social participation. What This Article Adds: Occupational therapy practitioners may use the available literature along with clinical reasoning to improve work, leisure, and social participation outcomes among clients poststroke. Additional research is required to build stronger evidence to support clinical decision making in stroke rehabilitation in these areas.

Development and Refinement of the American Occupational Therapy Association's Knowledge Translation Toolkit.

IMPORTANCE: Occupational therapy practitioners are expected to translate promising discoveries from empirical research into routine practice with their clients. However, complex barriers can influence practitioners' knowledge translation (KT) efforts, leading the American Occupational Therapy Association's Evidence-Based Practice (EBP) group to develop the KT Toolkit tailored to the perceived needs of occupational therapists and occupational therapy assistants. OBJECTIVE: To identify common barriers to implementing EBPs and potential strategies to support EBP uptake. DESIGN: Cross-sectional survey. SETTING: United States. PARTICIPANTS: Occupational therapy practitioners. OUTCOMES AND MEASURES: Data underwent descriptive and directed content analysis, the latter of which was guided by the Consolidated Framework for Implementation Research. RESULTS: Occupational therapy survey respondents (N = 818) identified common EBP implementation barriers (e.g., lack of time and resources, difficulty understanding research findings). Initial KT Toolkit content was developed to address these barriers and included resources for searching for, analyzing, and applying evidence in practice. CONCLUSIONS AND RELEVANCE: Survey findings have informed the development of the KT Toolkit, which includes resources designed to support occupational therapy practitioners' EBP implementation efforts. This KT Toolkit is available at AOTA.org and will be continuously revised and updated on an ongoing basis. What This Article Adds: Several barriers limit the extent to which occupational therapy practitioners can implement evidence with their client populations. The KT Toolkit is directly informed by practitioner input and provides resources to support practitioners in their efforts to translate knowledge into real-world practice.

RELMα Licenses Macrophages for Damage-Associated Molecular Pattern Activation to Instigate Pulmonary Vascular Remodeling.

Pulmonary hypertension (PH) is a debilitating disease characterized by remodeling of the lung vasculature. In rodents, resistin-like molecule-α (RELMα, also known as HIMF or FIZZ1) can induce PH, but the signaling mechanisms are still unclear. In this study, we used human lung samples and a hypoxia-induced mouse model of PH. We found that the human homolog of RELMα, human (h) resistin, is upregulated in macrophage-like inflammatory cells from lung tissues of patients with idiopathic PH. Additionally, at PH onset in the mouse model, we observed RELMα-dependent lung accumulation of macrophages that expressed high levels of the key damage-associated molecular pattern (DAMP) molecule high-mobility group box 1 (HMGB1) and its receptor for advanced glycation end products (RAGE). In vitro, RELMα/hresistin-induced macrophage-specific HMGB1/RAGE expression and facilitated HMGB1 nucleus-to-cytoplasm translocation and extracellular secretion. Mechanistically, hresistin promoted HMGB1 posttranslational lysine acetylation by preserving the NAD+-dependent deacetylase sirtuin (Sirt) 1 in human macrophages. Notably, the hresistin-stimulated macrophages promoted apoptosis-resistant proliferation of human pulmonary artery smooth muscle cells in an HMGB1/RAGE-dependent manner. In the mouse model, RELMα also suppressed the Sirt1 signal in pulmonary macrophages in the early posthypoxic period. Notably, recruited macrophages in the lungs of these mice carried the RELMα binding partner Bruton tyrosine kinase (BTK). hResistin also mediated the migration of human macrophages by activating BTK in vitro. Collectively, these data reveal a vascular-immune cellular interaction in the early PH stage and suggest that targeting RELMα/DAMP-driven macrophages may offer a promising strategy to treat PH and other related vascular inflammatory diseases.

Using a hybrid agent-based and equation based model to test school closure policies during a measles outbreak.

BACKGROUND: In order to be prepared for an infectious disease outbreak it is important to know what interventions will or will not have an impact on reducing the outbreak. While some interventions might have a greater effect in mitigating an outbreak, others might only have a minor effect but all interventions will have a cost in implementation. Estimating the effectiveness of an intervention can be done using computational modelling. In particular, comparing the results of model runs with an intervention in place to control runs where no interventions were used can help to determine what interventions will have the greatest effect on an outbreak. METHODS: To test the effects of a school closure policy on the spread of an infectious disease (in this case measles) we run simulations closing schools based on either the proximity of the town to the initial outbreak or the centrality of the town within the network of towns in the simulation. To do this we use a hybrid model that combines an agent-based model with an equation-based model. In our analysis, we use three measures to compare the effects of different intervention strategies: the total number of model runs leading to an outbreak, the total number of infected agents, and the geographic spread of outbreaks. RESULTS: Our results show that closing down the schools in the town where an outbreak begins and the town with the highest in degree centrality provides the largest reduction in percent of runs leading to an outbreak as well as a reduction in the geographic spread of the outbreak compared to only closing down the town where the outbreak begins. Although closing down schools in the town with the closest proximity to the town where the outbreak begins also provides a reduction in the chance of an outbreak, we do not find the reduction to be as large as when the schools in the high in degree centrality town are closed. CONCLUSIONS: Thus we believe that focusing on high in degree centrality towns during an outbreak is important in reducing the overall size of an outbreak.

Role of Occupational Therapy in Facilitating Participation Among Caregivers of People With Parkinson's Disease: A Systematic Review.

IMPORTANCE: Caregivers play a critical role in facilitating the performance of people with Parkinson's disease (PD). Knowledge on how occupational therapy practitioners can mitigate the negative effects of caregiving is needed to enable caregiver participation. OBJECTIVE: To explore the effectiveness of interventions within the scope of occupational therapy practice for caregivers of people with PD to facilitate or maintain their participation in the caregiver role. DATA SOURCES: We conducted a systematic review of the literature published in CINAHL, MEDLINE, PsycINFO, and OTseeker between 2011 and 2019. Article reference lists were also hand searched for additional articles. Study Selection and Data Collection: Articles were screened and evaluated using the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines. The review was conducted in accordance with steps outlined by the American Occupational Therapy Association's Evidence-Based Practice Project. FINDINGS: Six articles met the inclusion criteria. Interventions in each article were distinct, prohibiting theme development. Overall, the strength of evidence was low, and the risk of bias was high. None of the studies included in this review were obtained from the occupational therapy literature. CONCLUSIONS AND RELEVANCE: Little evidence is available to support interventions within the scope of occupational therapy practice for caregivers of people with PD. Existing evidence suggests that interventions need to be flexible (e.g., in terms of time, cost, and delivery method) and tailored to the unique needs of this population. What This Article Adds: There is a continued need to develop occupational therapy interventions that support participation in the caregiving role for caregivers of people with PD.

Interventions Within the Scope of Occupational Therapy to Improve Activities of Daily Living, Rest, and Sleep in People With Parkinson's Disease: A Systematic Review.

IMPORTANCE: People with Parkinson's disease (PD) commonly experience difficulty in performing activities of daily living (ADLs), which affects their perceived quality of life. OBJECTIVE: To examine the evidence for the effectiveness of interventions within the scope of occupational therapy to improve performance and participation in ADLs, rest, and sleep in adults with PD. DATA SOURCES: Databases searched were MEDLINE, PsycINFO, CINAHL, OTseeker, and Cochrane Collection. Included articles were published between January 2011 and December 2018. Study Selection and Data Collection: Articles describing Level 1b, 2b, and 3b studies that examined outcomes related to ADLs, rest, and sleep in people with PD were included following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. FINDINGS: Forty-five articles (10 Level 1b, 27 Level 2b, and 8 Level 3b) met the inclusion criteria. CONCLUSIONS AND RELEVANCE: Strong strength of evidence was found to support inpatient multidisciplinary intensive rehabilitation treatment (MIRT) to improve ADLs, and moderate strength of evidence that MIRT improves sleep performance. Low strength of evidence was present for outpatient occupational therapy to improve ADL and sleep outcomes. Low strength of evidence was found for resistance exercise programs to improve ADLs, but moderate strength of evidence indicates that multimodal exercise programs and targeted exercise programs can improve ADLs. Low to moderate strength of evidence suggested that alternative therapies and cognitive-behavioral therapy have a positive impact on ADLs and sleep. These results can be used to inform evidence-based occupational therapy practice. What This Article Adds: This article provides information for practitioners on the effectiveness of interventions within the scope of occupational therapy practice to improve ADLs and sleep.

Occupational Therapy Interventions for Instrumental Activities of Daily Living for Adults With Parkinson's Disease: A Systematic Review.

IMPORTANCE: Instrumental activities of daily living (IADLs) are important for independence, safety, and productivity, and people with Parkinson's disease (PD) can experience IADL limitations. Occupational therapy practitioners should address IADLs with their clients with PD. OBJECTIVE: To systematically review the evidence for the effectiveness of occupational therapy interventions to improve or maintain IADL function in adults with PD. DATA SOURCES: MEDLINE, CINAHL, PsycINFO, OTseeker, and Cochrane databases from January 2011 to December 2018. Study Selection and Data Collection: Primary inclusion criteria were peer-reviewed journal articles describing Level 1-3 studies that tested the effect of an intervention within the scope of occupational therapy on an IADL outcome in people with PD. Three reviewers assessed records for inclusion, quality, and validity following Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. FINDINGS: Twenty-two studies met the inclusion criteria and were categorized into four themes on the basis of primary focus or type of intervention: physical activity, specific IADL-focused, cognitive rehabilitation, and individualized occupational therapy interventions. There were 9 Level 1b, 9 Level 2b, and 4 Level 3b studies. Strong strength of evidence was found for the beneficial effect of occupational therapy-related interventions for physical activity levels and handwriting, moderate strength of evidence for IADL participation and medication adherence, and low strength of evidence for cognitive rehabilitation. CONCLUSIONS AND RELEVANCE: Occupational therapy interventions can improve health management and maintenance (i.e., physical activity levels, medication management), handwriting, and IADL participation for people with PD. Further research is needed on cognitive rehabilitation. This review is limited by the small number of studies that specifically addressed IADL function in treatment and as an outcome. What This Article Adds: Occupational therapy intervention can be effective in improving or maintaining IADL performance and participation in people with PD. Occupational therapy practitioners can address IADL function through physical activity interventions, interventions targeting handwriting and medication adherence, and individualized occupational therapy interventions.

Neonatal Isoflurane Anesthesia or Disruption of Postsynaptic Density-95 Protein Interactions Change Dendritic Spine Densities and Cognitive Function in Juvenile Mice.

BACKGROUND: Experimental evidence shows postnatal exposure to anesthesia negatively affects brain development. The PDZ2 domain, mediating protein-protein interactions of the postsynaptic density-95 protein, serves as a molecular target for several inhaled anesthetics. The authors hypothesized that early postnatal disruption of postsynaptic density-95 PDZ2 domain interactions has persistent effects on dendritic spines and cognitive function. METHODS: One-week-old mice were exposed to 1.5% isoflurane for 4 h or injected with 8 mg/kg active postsynaptic density-95 wild-type PDZ2 peptide along with their respective controls. A subset of these mice also received 4 mg/kg of the nitric oxide donor molsidomine. Hippocampal spine density, long-term potentiation, novel object recognition memory, and fear learning and memory were evaluated in mice. RESULTS: Exposure of 7-day-old mice to isoflurane or postsynaptic density-95 wild-type PDZ2 peptide relative to controls causes: (1) a long-term decrease in mushroom spines at 7 weeks (mean ± SD [spines per micrometer]): control (0.8 ± 0.2) versus isoflurane (0.4 ± 0.2), P < 0.0001, and PDZ2MUT (0.7 ± 0.2) versus PDZ2WT (0.4 ± 0.2), P < 0.001; (2) deficits in object recognition at 6 weeks (mean ± SD [recognition index]): naïve (70 ± 8) versus isoflurane (55 ± 14), P = 0.010, and control (65 ± 13) versus isoflurane (55 ± 14), P = 0.045, and PDZ2MUT (64 ±11) versus PDZ2WT (53 ± 18), P = 0.045; and (3) deficits in fear learning at 7 weeks and memory at 8 weeks (mean ± SD [% freezing duration]): Learning, control (69 ± 12) versus isoflurane (52 ± 13), P < 0.0001, and PDZ2MUT (65 ± 14) versus PDZ2WT (55 ± 14) P = 0.011, and Memory, control (80 ± 17) versus isoflurane (56 ± 23), P < 0.0001 and PDZ2MUT (73 ± 18) versus PDZ2WT (44 ± 19) P < 0.0001. Impairment in long-term potentiation has fully recovered here at 7 weeks (mean ± SD [% baseline]): control (140 ± 3) versus isoflurane (137 ± 8), P = 0.560, and PDZ2MUT (136 ± 17) versus PDZ2WT (128 ± 11), P = 0.512. The isoflurane induced decrease in mushroom spines was preventable by introduction of a nitric oxide donor. CONCLUSIONS: Early disruption of PDZ2 domain-mediated protein-protein interactions mimics isoflurane in decreasing mushroom spine density and causing learning and memory deficits in mice. Prevention of the decrease in mushroom spine density with a nitric oxide donor supports a role for neuronal nitric oxide synthase pathway in mediating this cellular change associated with cognitive impairment.

Evaluation of LDBio Aspergillus ICT Lateral Flow Assay for IgG and IgM Antibody Detection in Chronic Pulmonary Aspergillosis.

Detecting Aspergillus-specific IgG is critical to diagnosing chronic pulmonary aspergillosis (CPA). Existing assays are often cost- and resource-intensive and not compatible with resource-constrained laboratory settings. LDBio Diagnostics has recently commercialized a lateral flow assay based on immunochromatographic technology (ICT) that detects Aspergillus antibodies (IgG and IgM) in less than 30 min, requiring minimal laboratory equipment. A total of 154 CPA patient sera collected at the National Aspergillosis Centre (Manchester, United Kingdom) and control patient sera from the Peninsula Research Bank (Exeter, United Kingdom) were evaluated. Samples were applied to the LDBio Aspergillus ICT lateral flow assay, and results were read both visually and digitally. Results were compared with Aspergillus IgG titers in CPA patients, measured by ImmunoCAP-specific IgG assays. For proven CPA patients versus controls, sensitivity and specificity for the LDBio Aspergillus ICT were 91.6% and 98.0%, respectively. In contrast, the routinely used ImmunoCAP assay exhibited 80.5% sensitivity for the same cohort (cutoff value, 40 mg of antigen-specific antibodies [mgA]/liter). The assay is easy to perform but challenging to read when only a very faint band is present (5/154 samples tested). The ImmunoCAP Aspergillus IgG titer was also compared with the Aspergillus ICT test line intensity or rate of development, with weak to moderate correlations. The Aspergillus ICT lateral flow assay exhibits excellent sensitivity for serological diagnosis of CPA. Quantifying IgG from test line intensity measurements is not reliable. Given the short run time, simplicity, and limited resources needed, the LDBio Aspergillus ICT is a suitable diagnostic tool for CPA in resource-constrained settings.

Genetically informed captive breeding of hybrids of an extinct species of Galapagos tortoise.

Hybridization poses a major challenge for species conservation because it threatens both genetic integrity and adaptive potential. Yet, hybridization can occasionally offer unprecedented opportunity for species recovery if the genome of an extinct taxon is present among living hybrids such that selective breeding could recapture it. We explored the design elements for establishing a captive-breeding program for Galapagos tortoises (Chelonoidis spp.) built around individuals with admixed ancestry involving an extinct species. The target individuals were hybrids between the extinct species from Floreana Island, C. niger, and an extant species, C. becki, which were recently found in the endemic range of C. becki, from Wolf Volcano on Isabela Island. We combined genotypic data from 35 tortoises with high ancestry from C. niger with forward-in-time simulations to explore captive breeding strategies that maximized overall genetic diversity and ancestry from C. niger while accommodating resource constraints, species biology, and the urgency to return tortoises to Floreana Island for facilitating ecosystem restoration. Overall genetic diversity was maximized when in the simulation tortoises were organized in relatively small breeding groups. Substantial amounts of the C. niger genome were captured despite limited resources available for selectively breeding tortoises in captivity. Genetic diversity was maximized when captive-bred offspring were released to the wild rather than being used as additional breeders. Our results provide genetic-based and practical guidance on the inclusion of hybrids with genomic representation from extinct taxa into species restoration programs and informs the ongoing debate on the value of hybrids in biodiversity conservation.

Reproducción en Cautiverio Informada Genéticamente de Híbridos de una Especie Extinta de Tortuga de las Galápagos Resumen La hibridación representa un obstáculo importante para la conservación de especies ya que amenaza tanto a la integridad genética como al potencial adaptativo. Aun así, la hibridación ocasionalmente puede ofrecer una oportunidad sin precedentes para la recuperación de una especie si el genoma de un taxón extinto está presente entre los híbridos vivientes de tal manera que la reproducción selectiva pudiera recuperarlo. Exploramos los elementos de diseño para el establecimiento de un programa de reproducción en cautiverio de la tortuga de las Galápagos (Chelonoidis spp.) construido en torno a los individuos con linajes mixtos que incluyeran una especie extinta. Los individuos fueron los híbridos de la especie extinta en la Isla Floreana, C. niger, y la especie viviente C. becki, encontrados recientemente en la distribución geográfica endémica de la segunda especie en el Volcán Wolf (Isla Isabela). Combinamos los datos genotípicos de 35 tortugas con un linaje cargado de C. niger usando simulaciones futuras de la descendencia generada por el programa para explorar las estrategias de reproducción en cautiverio que maximizaran en general la diversidad genética y el linaje de C. niger a la vez que se ajustaba a las restricciones de recursos, la biología de la especie y la urgencia por regresar las tortugas a la Isla Floreana para facilitar la restauración del ecosistema. En general, la diversidad genética se maximizó cuando en la simulación las tortugas estuvieron organizadas en grupos de reproducción relativamente pequeños y cuando cantidades sustanciales del genoma de C. niger fueron capturados con base en los recursos disponibles para reproducir selectivamente a las tortugas en cautiverio. La diversidad genética se vio especialmente maximizada cuando las crías reproducidas en cautiverio fueron liberadas en lugar de ser utilizadas como reproductoras adicionales. Nuestros resultados proporcionan una guía práctica y basada en la genética para la inclusión de híbridos con representación genómica de un taxón extinto en los programas de restauración de especies. Cuando incorporamos a los híbridos con diversidad genética que previamente se creía perdida en los programas con el propósito de la reintroducción de especies, nuestro estudio informa al debate continuo sobre el valor de los híbridos para la conservación de la biodiversidad.

AOTA's Top 5 Choosing Wisely® Recommendations.

Health care spending in the United States continues to grow at an unsustainable rate. In 2015, spending increased 5.8%, to reach $3.2 trillion, or $9,990 per person. As a share of the nation's gross domestic product, health spending accounted for 17.8% (Morgan et al., 2016). A critical component of addressing this issue is eliminating wasteful spending without reducing quality and appropriate care. In 2012, Choosing Wisely®, an initiative of the ABIM Foundation (American Board of Internal Medicine), started with the aim to encourage meaningful conversations between health care practitioners and clients to ensure that appropriate and quality care is being provided. The American Occupational Therapy Association (AOTA) made a commitment to join Choosing Wisely in 2016. With support and input from AOTA members, the Board of Directors, and staff, AOTA implemented a three-phase process to develop and publish the list, "Five Things Patients and Providers Should Question." The goal of AOTA's participation in this initiative is to start dialogue within the occupational therapy profession about providing quality services that are supported by evidence, not duplicative, free from harm, and truly necessary.

Occupational Therapy Interventions to Improve Performance of Instrumental Activities of Daily Living for Community-Dwelling Older Adults: A Systematic Review.

OBJECTIVE: We examined the effectiveness of interventions within the scope of occupational therapy to improve the performance of instrumental activities of daily living (IADLs) for community-dwelling older adults. METHOD: We searched and examined the literature (2008 through 2016) using four electronic databases. Fourteen studies met the inclusion criteria and were critically appraised and synthesized. RESULTS: Analysis revealed four thematic areas: cognitive, self-management, prevention, and home-based multidisciplinary rehabilitation interventions. Strong evidence supports the use of tailored, multidisciplinary, home-based care programs to support older adults to maintain IADL improvements over time and the use of cognitive interventions to improve memory, executive function, functional status, and everyday problem solving. In addition, strong evidence indicates that tailored home-based preventive sessions were beneficial to mediate functional disability and satisfaction with performance. CONCLUSION: Evidence supports tailored interventions designed to enhance IADL performance. More studies are needed that focus on IADLs specifically and that use IADLs in their interventions.

Occupational Therapy Interventions for Adults With Musculoskeletal Conditions.

Evidence Connection articles provide a clinical application of systematic reviews developed in conjunction with the American Occupational Therapy Association's (AOTA's) Evidence-Based Practice Project. In this Evidence Connection article, we describe a case report of a person who underwent a total knee replacement due to severe osteoarthritis of his left knee. The occupational therapy assessment and intervention process both before and after surgery in the home setting is described. Findings from the systematic review (Dorsey & Bradshaw, 2017) on this topic were published in the January/February 2017 issue of the American Journal of Occupational Therapy and in AOTA's Occupational Therapy Practice Guidelines for Adults With Musculoskeletal Conditions. Each article in this series summarizes the evidence from the published reviews on a given topic and presents an application of the evidence to a related clinical case. Evidence Connection articles illustrate how the research evidence from the reviews can be used to inform and guide clinical reasoning.

Using environmental heterogeneity to plan for sea-level rise.

Environmental heterogeneity is increasingly being used to select conservation areas that will provide for future biodiversity under a variety of climate scenarios. This approach, termed conserving nature's stage (CNS), assumes environmental features respond to climate change more slowly than biological communities, but will CNS be effective if the stage were to change as rapidly as the climate? We tested the effectiveness of using CNS to select sites in salt marshes for conservation in coastal Georgia (U.S.A.), where environmental features will change rapidly as sea level rises. We calculated species diversity based on distributions of 7 bird species with a variety of niches in Georgia salt marshes. Environmental heterogeneity was assessed across six landscape gradients (e.g., elevation, salinity, and patch area). We used 2 approaches to select sites with high environmental heterogeneity: site complementarity (environmental diversity [ED]) and local environmental heterogeneity (environmental richness [ER]). Sites selected based on ER predicted present-day species diversity better than randomly selected sites (up to an 8.1% improvement), were resilient to areal loss from SLR (1.0% average areal loss by 2050 compared with 0.9% loss of randomly selected sites), and provided habitat to a threatened species (0.63 average occupancy compared with 0.6 average occupancy of randomly selected sites). Sites selected based on ED predicted species diversity no better or worse than random and were not resilient to SLR (2.9% average areal loss by 2050). Despite the discrepancy between the 2 approaches, CNS is a viable strategy for conservation site selection in salt marshes because the ER approach was successful. It has potential for application in other coastal areas where SLR will affect environmental features, but its performance may depend on the magnitude of geological changes caused by SLR. Our results indicate that conservation planners that had heretofore excluded low-lying coasts from CNS planning could include coastal ecosystems in regional conservation strategies.
