Development and Feasibility Pilot Study of Indigenous Recovery Planning: A Community-Engaged Approach to Addressing Substance Use in a Native Community.

Although Native (American Indian and Alaska Native [AI/AN]) populations have high rates of abstinence from alcohol, health problems associated with substance use remain a pressing concern in many AI/AN communities. As part of a longstanding community-based participatory research (CBPR) project involving five years of relationship building and three preliminary studies, our team of academic and community co-researchers developed a culturally grounded intervention to facilitate recovery from substance use disorders among tribal members from a rural AI reservation. Our Indigenous Recovery Planning (IRP) intervention consists of six weekly sessions and aims to provide inroads to existing resources in the community, affirm and enhance Native identity, address culturally relevant risk factors, and build upon strengths. Results from a feasibility pilot study (N = 15) suggest that IRP is feasible to implement and acceptable to the community. Although there was insufficient statistical power to conduct hypothesis testing, there were changes between pretest and posttest scores in the expected directions. Future directions and limitations of this research are discussed.

Reliability and validity of diabetes nutrition self-efficacy and behavior measures for the "What Can I Eat" diabetes nutrition education program for American Indian and Alaska Native adults with type 2 diabetes.

BACKGROUND: American Indian and Alaska Native (AI/AN) people have high rates of diabetes and limited access to nutrition education. The "What Can I Eat?" (WCIE) diabetes nutrition education program was culturally adapted for AI/AN adults. OBJECTIVE: This analysis was designed to evaluate the reliability and validity of items developed to measure diabetes nutrition self-efficacy (i.e., confidence one can engage in specific behaviors) and diabetes nutrition behavior among participants in the WCIE program for AI/AN adults. DESIGN: This study was a secondary analysis of data from a randomized controlled trial designed to evaluate the WCIE program for AI/AN adults. Baseline data were used to assess the reliability and validity of the self-efficacy and behavior items, which were collected via survey. Due to COVID-19 safety protocols, the intervention was conducted via Zoom, and both survey and clinical data were collected at home by participants. PARTICIPANTS/SETTING: The study was conducted from January to December 2021 with five AI/AN-serving health care programs in Oklahoma, Illinois, North Carolina, California, and New York. AI/AN adults with type 2 diabetes who spoke English and had Internet access were eligible. Sixty participated. MAIN OUTCOME MEASURES: Analyses examined validity and reliability of diabetes nutrition self-efficacy and behavior items. STATISTICAL ANALYSIS PERFORMED: To test reliability, internal consistency and factor structures of the scales were examined. To evaluate convergent validity, Pearson correlations were computed to examine the association of the self-efficacy and behavior measures with each other and with clinical indicators (i.e., Body Mass Index, blood pressure, hemoglobin A1C). RESULTS: Two self-efficacy factors were identified. Each showed strong internal consistency (Cronbach alphas ≥ 0.85; McDonald omegas ≥ 0.88) and was directly associated with diabetes nutrition behavior (Ps < 0.001). The factor assessing Confidence in Using the Diabetes Plate was inversely associated with A1C (Pearson Correlation = -0.32, P = 0.0243). The behavior measure capturing Healthy Nutrition Behavior showed strong internal consistency (alpha = 0.89; omega = 0.92) and was inversely associated with A1C (Pearson Correlation = - 0.38, P = 0.0057). CONCLUSIONS: Diabetes nutrition self-efficacy and behavior items developed for the WCIE program for AI/AN adults are valid and reliable. These items can facilitate rigorous and consistent evaluation of the AI/AN WCIE program.

Exposure of an endangered seabird species to persistent organic pollutants: Assessing levels in blood and link with reproductive parameters.

Ocean contamination, particularly from persistent organic pollutants (POPs), remains a significant threat to marine predators that occupy high trophic positions. Long-lived procellariform seabirds are apex predators in marine ecosystems and tend to accumulate contaminants. Prolonged exposure to pollutants negatively affects their fitness including reproductive success. Low breeding success may represent a hurdle for the restoration of small and endangered seabird populations, including several highly threatened gadfly petrels. Here we investigated the annual variation (2019 and 2022) in organochlorine pesticide (OCP), polychlorinated biphenyl ether (PCB), polybrominated diphenyl ether (PBDE), and polycyclic aromatic hydrocarbon (PAH) exposure in the endangered Bermuda petrel (Pterodroma cahow), and the relationship between female contaminant burden and breeding parameters. We found that petrels were exposed to a wide range of pollutants (33 out of 55 showed measurable levels) with PCBs dominating the blood contaminant profiles in both years. Only 9 compounds were detected in >50 % of the birds. Specifically, among OCPs, p, p'-DDE and hexaclorobenzene were the most frequently detected while fluorene and acenaphthene were the most common PAH. The concentrations of ∑5PCBs and ∑7POPs were higher in older birds. Furthermore, females with greater contaminant burdens laid eggs with a lower probability of hatching. However, female investment in egg production (size and volume) was unrelated to their blood contaminant load. Overall, this study highlights the presence of a wide range of contaminants in the petrel's food web, and it sheds light on the potential impact of chronic exposure to sub-lethal levels of PCBs on the breeding success of seabirds. We claim that toxicological testing should be a practice integrated in the management of seabirds, particularly of endangered species to monitor how past and present anthropogenic activities impact their conservation status.

A Novel DNase Assay Reveals Low DNase Activity in Severe Asthma.

Secreted deoxyribonucleases (DNases), such as DNase-1 and DNase-IL3, degrade extracellular DNA, and endogenous DNases have roles in resolving airway inflammation and guarding against autoimmune responses to nucleotides. Subsets of patients with asthma have high airway DNA levels, but information about DNase activity in health and in asthma is lacking. To characterize DNase activity in health and in asthma, we developed a novel kinetic assay using a Taqman probe sequence that is quickly cleaved by DNase-I to produce a large product signal. We used this kinetic assay to measure DNase activity in sputum from participants in the Severe Asthma Research Program (SARP)-3 (n=439) and from healthy controls (n=89). We found that DNase activity was lower than normal in asthma (78.7 RFU/min vs 120.4 RFU/min, p<0.0001). Compared to asthma patients with sputum DNase activity levels in the upper tertile activity levels, those in the lower tertile of sputum DNase activity were characterized clinically by more severe disease and pathologically by airway eosinophilia and airway mucus plugging. Carbamylation of DNase-I, a post translational modification that can be mediated by eosinophil peroxidase, inactivated DNase-I. In summary, a Taqman probe-based DNase activity assay uncovers low DNase activity in the asthma airway which is associated with more severe disease and airway mucus plugging and may be caused, at least in part, by eosinophil-mediated carbamylation.

An economic evaluation of an early palliative care intervention among patients with advanced cancer.

BACKGROUND: Early integration of palliative care into oncology care has shown positive effects on patient symptoms and quality of life. It may also reduce health care costs. However given the heterogeneity of settings and interventions and the lack of information on the minimally effective dose for influencing care utilisation and costs, it remains uncertain whether early palliative care reduces costs. OBJECTIVES: We sought to determine whether an early palliative care intervention integrated in usual oncology care in a Swiss hospital setting reduced utilisation and costs of health care in the last month of life when compared with usual oncology care alone. METHODS: We performed a cost-consequences analysis alongside a multicentre trial. We extracted costs from administrative health insurance data and health care utilisation from family caregiver surveys to compare two study arms: usual oncology care and usual oncology care plus the palliative care intervention. The intervention consisted of a single-structured, multiprofessional conversation with the patient about symptoms, end-of-life decisions, network building and support for carers (SENS). The early palliative care intervention was performed within 16 weeks of the diagnosis of a tumour stage not amenable or responsive to curative treatment. RESULTS: We included 58 participants with advanced cancer in our economic evaluation study. Median overall health care costs in the last month of life were 7892 Swiss Francs (CHF) (interquartile range: CHF 5637-13,489) in the intervention arm and CHF 8492 [CHF 5411-12,012] in the control arm. The average total intervention treatment cost CHF 380 per patient. Integrating an early palliative care intervention into usual oncology care showed no significant difference in health care utilisation or overall health care costs between intervention and control arms (p = 0.98). CONCLUSION: Although early palliative care is often presented as a cost-reducing care service, we could not show a significant effect of the SENS intervention on health care utilisation and costs in the last month of life. However, it may be that the intervention was not intensive enough, the timeframe too short or the study population too small for measurable effects. Patients appreciated the intervention. Single-structured early palliative care interventions are easy to implement in clinical practice and present low treatment costs. Further research about the economic impact of early palliative care should focus on extracting large, detailed cost databases showing potential shifts in cost and cost-effectiveness.

Evaluation of the Effectiveness of Amlexanox in the Treatment of Erosive Oral Lichen Planus: A Clinical Experience from a Tertiary Care Center.

Aim: This comparative study evaluated the effectiveness and safety profile of topical amlexanox and triamcinolone for the management of erosive oral lichen planus (EOLP). Materials and Methods: This prospective, observational study included 21 patients diagnosed clinically and histopathologically with EOLP and categorized into two groups. Subjects in the two groups were prescribed topical amlexanox and triamcinolone, respectively, for 4 weeks. The area of the erosive lesion and burning sensation was measured at baseline, at the end of the first, 2second, and fourth week. These outcome measures were documented and statistically analyzed. The statistical analyses were performed using the IBM SPSS Statistics version 22. Analysis for age distribution was done by independent sample t test. Analysis of sex distribution was done by chi-square test. Variations within a single group for both the outcome parameters were calculated by Wilcoxon signed rank test. (P < 0.05 statistically significant). Results: A total of 30 erosive sites were evaluated in 21 patients over a 4-week duration. The most common site was the buccal mucosa in both groups (23 of 30; 76.67% of total lesions assessed), followed by the tongue (5 of 30; 16.67% of total lesions assessed), the palate (1 of 30; 3.33% of total sites assessed), and the maxillary attached gingiva (1 of 30; 3.33% of total sites assessed). Group 1 (amlexanox) was comprised of 11 subjects, whereas Group 2 (triamcinolone) was comprised of 10 subjects. Pre and posttreatment comparison revealed no statistically significant difference (P = 0.756; 0.512, respectively), for the area of the erosion and burning sensation. Intragroup analysis showed that in Groups 1 and 2, there was a statistically significant reduction in the measures posttreatment (P < 0.05). Conclusions: Amlexanox provides an earlier onset of pain relief in the treatment of EOLP, whereas providing a comparable reduction in the erosive area compared with triamcinolone. Topical amlexanox appears to be as effective as triamcinolone and is a promising alternative in the management of the erosive lichen planus with minimal adverse effects.

Allochrony is shaped by foraging niche segregation rather than adaptation to the windscape in long-ranging seabirds.

BACKGROUND: Ecological segregation allows populations to reduce competition and coexist in sympatry. Using as model organisms two closely related gadfly petrels endemic to the Madeira archipelago and breeding with a two month allochrony, we investigated how movement and foraging preferences shape ecological segregation in sympatric species. We tested the hypothesis that the breeding allochrony is underpinned by foraging niche segregation. Additionally, we investigated whether our data supported the hypothesis that allochrony is driven by species-specific adaptations to different windscapes. METHODS: We present contemporaneous tracking and stable isotopes datasets for Zino's (Pterodroma madeira) and Desertas (Pterodroma deserta) petrels. We quantified the year-round distribution of the petrels, characterised their isotopic niches and quantified their habitat preferences using machine learning (boosted regression trees). Hidden-Markov-models were used to investigate the effect of wind on the central-place movement speed, and a simulation framework was developed to investigate whether each species breeds at times when the windscape is most favourable to sustain their trips. RESULTS: Despite substantial spatial overlap throughout the year, the petrels exhibited diverging isotopic niches and habitat preferences during breeding. Both species used a vast pelagic region in the North Atlantic, but targeted two different mesopelagic ecoregions and showed a preference for habitats mostly differing in sea surface temperature values. Based on our simulation framework, we found that both species would perform trips of similar speed during the other species' breeding season. CONCLUSIONS: The different breeding schedules between the species are underpinned by differences in foraging habitat preferences and adaptation to the local environment, rather than to the windscape. Nevertheless, the larger Desertas petrels exploited significantly windier conditions, potentially unsustainable for the smaller Zino's petrels. Furthermore, due to larger mass and likely higher fasting endurance, Desertas petrels engaged in central-place-foraging movements that covered more ground and lasted longer than those of Zino's petrels. Ultimately, patterns of ecological segregation in sympatric seabirds are shaped by a complex interplay between foraging and movement ecology, where morphology, foraging trip regulation and fasting endurance have an important- yet poorly understood- role.

Single-cell dissection of the human motor and prefrontal cortices in ALS and FTLD.

Amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) share many clinical, pathological, and genetic features, but a detailed understanding of their associated transcriptional alterations across vulnerable cortical cell types is lacking. Here, we report a high-resolution, comparative single-cell molecular atlas of the human primary motor and dorsolateral prefrontal cortices and their transcriptional alterations in sporadic and familial ALS and FTLD. By integrating transcriptional and genetic information, we identify known and previously unidentified vulnerable populations in cortical layer 5 and show that ALS- and FTLD-implicated motor and spindle neurons possess a virtually indistinguishable molecular identity. We implicate potential disease mechanisms affecting these cell types as well as non-neuronal drivers of pathogenesis. Finally, we show that neuron loss in cortical layer 5 tracks more closely with transcriptional identity rather than cellular morphology and extends beyond previously reported vulnerable cell types.

Optimization of Potent Ligands for the E3 Ligase DCAF15 and Evaluation of Their Use in Heterobifunctional Degraders.

Unlocking novel E3 ligases for use in heterobifunctional PROTAC degraders is of high importance to the pharmaceutical industry. Over-reliance on the current suite of ligands used to recruit E3 ligases could limit the potential of their application. To address this, potent ligands for DCAF15 were optimized using cryo-EM supported, structure-based design to improve on micromolar starting points. A potent binder, compound 24, was identified and subsequently conjugated into PROTACs against multiple targets. Following attempts on degrading a number of proteins using DCAF15 recruiting PROTACs, only degradation of BRD4 was observed. Deconvolution of the mechanism of action showed that this degradation was not mediated by DCAF15, thereby highlighting both the challenges faced when trying to expand the toolbox of validated E3 ligase ligands for use in PROTAC degraders and the pitfalls of using BRD4 as a model substrate.

Safety and Treatment Outcomes of Infants and Children Treated With Daptomycin: Six-Year Experience From a Pediatric Academic Medical Center.

Daptomycin is a common treatment for serious infections caused by gram-positive bacteria in adult patients; however, data regarding its safety and efficacy in the pediatric population are limited. This was a retrospective chart review of adverse reactions and treatment outcomes associated with daptomycin use in children <13 years old who received at least 1 dose of daptomycin. At least 1 dose of daptomycin was received by 147 patients. Seventy-two patients received daptomycin for 5 or more days. New-onset loose stools on daptomycin initiation were reported for 14 (9.5%) patients, elevations in creatine kinase in 3 (2%) patients, and elevated aspartate transaminase and alanine transaminase in 13 (8.8%) and 9 (6.1%) patients, respectively. Two patients (1.4%) had daptomycin discontinued due to specific concerns for adverse drug reactions. Daptomycin was found to be safe and effective in this pediatric cohort that included young children and infants with a variety of types and severities of infections.

Musculoskeletal and tendinous details of selected anomalies in the locomotor system of anurans.

Previous studies on anuran anomalies predominantly examine isolated cases or focus on external and skeletal features. Our study analyzes a comprehensive sample collected from 1991 to 2017, examining the muscle-tendon system in 24 anuran species across adult, juvenile, and metamorphic stages. This extensive sample size allows us to investigate consistent anomaly patterns across different developmental stages and anuran families, exploring potential common developmental or genetic factors. Our detailed anatomical examination, encompassing musculature, tendons, and skeletal structures, revealed that 21% of the specimens displayed anomalies, a noteworthy finding considering the extensive sample size and duration of the studied sample. Of these anomalies, 17% affected the locomotor system, predominantly in the upper limbs. Key anomalies included, forelimbs and hindlimbs brachydactyly, rotation in forelimbs, partial kyphotic lordosis, and scoliosis. Notably, the digit 4 in the forelimbs and digits 4 and 5 in the hindlimbs were particularly susceptible to teratogenic effects, indicating possible prolonged exposure during development. Our study also uncovered combinations of anomalies and identified a phenotype similar to Poland syndrome. The findings validate the "Logic of Monsters" (LoMo theory) by Alberch, although the name itself may not be deemed appropriate, showing that developmental disruptions in tetrapods are not random but follow distinct sequences and patterns. The name, while unfortunate, accurately reflects the unusual nature of these developmental anomalies. This contributes to the evolving "Evo-Devo-Path" framework, highlighting the study's importance in understanding developmental disruptions in tetrapods.

Occurrence of antibiotics, hormones and PFAs in surface water from a Nile tilapia aquaculture facility in a Brazilian hydroelectric reservoir.

This study assessed the occurrence of five antibiotics, three hormones, caffeine, and long and short-chain perfluoroalkyl and polyfluoroalkyl substances (PFASs) in surface water and feedstuff samples obtained from aquaculture cages in Três Marias reservoir in Brazil. This is the first work to evaluate the presence of PFAS in surface water used for aquaculture in Brazil. Solid-phase extraction and low temperature partitioning extraction followed by liquid chromatography coupled to mass spectrometry (LC-MS) were performed to process and analyze surface water samples and feedstuff, respectively. The ecotoxicological risk quotient was calculated for target compounds detected in water. Ciprofloxacin and caffeine were detected in all surface water samples. Pharmaceutical drugs ranged from 0.7 ng L-1 (trimethoprim) to 389.2 ng L -1 (ß-estradiol). Estrone (10.24 ng g-1) and ß-estradiol (66.20 ng g-1) were also found in feedstuff. Four PFASs (PFOA, PFDoA, PFTeDA, and PFBS) were detected (9.40-15.2 µg L-1) at levels higher than reported in studies conducted worldwide. Ecotoxicological risk assessment indicated high risks for caffeine and PFOA, PFDoA, and PFTeDA with RQ values from 10 to 103. These findings reveal risks to biodiversity, ecosystem integrity and human health considering possible intake of these contaminants by fish consumption due to potential bioaccumulation of these substances. Hence, it is critical to conduct more studies in this direction in Brazil and other low and middle-low-income countries.

Development of personalized non-invasive ventilation masks for critically ill children: a bench study.

BACKGROUND: Obtaining a properly fitting non-invasive ventilation (NIV) mask to treat acute respiratory failure is a major challenge, especially in young children and patients with craniofacial abnormalities. Personalization of NIV masks holds promise to improve pediatric NIV efficiency. As current customization methods are relatively time consuming, this study aimed to test the air leak and surface pressure performance of personalized oronasal face masks using 3D printed soft materials. Personalized masks of three different biocompatible materials (silicone and photopolymer resin) were developed and tested on three head models of young children with abnormal facial features during preclinical bench simulation of pediatric NIV. Air leak percentages and facial surface pressures were measured and compared for each mask. RESULTS: Personalized NIV masks could be successfully produced in under 12 h in a semi-automated 3D production process. During NIV simulation, overall air leak performance and applied surface pressures were acceptable, with leak percentages under 30% and average surface pressure values mostly remaining under normal capillary pressure. There was a small advantage of the masks produced with soft photopolymer resin material. CONCLUSION: This first, proof-of-concept bench study simulating NIV in children with abnormal facial features, showed that it is possible to obtain biocompatible, personalized oronasal masks with acceptable air leak and facial surface pressure performance using a relatively short, and semi-automated production process. Further research into the clinical value and possibilities for application of personalized NIV masks in critically ill children is needed.

The presence of doping agents in dietary supplements: A glimpse into the Brazilian situation.

Dietary supplements (DS) are intended for healthy people to maintain or improve their overall health. Its consumption is widespread in large part of the general population and at all levels of athletes. Nevertheless, DS use can also pose health risks to individuals and, in the case of athletes, may lead to adverse analytical findings (AAFs) due to the possibility of DS contamination or adulteration with doping agents banned by the World Anti-Doping Agency. Although educational initiatives are being performed in Brazil to warn the sports community about inadvertent doping cases, AAFs connected to the DS administration have been increasingly growing. The findings of DS analyzed by the Brazilian Doping Control Laboratory (LBCD), between 2017 and 2022, after Testing Authorities (TAs) analysis requests, showed an alarming number of tainted samples. Diuretics were the most common adulterants found in all supplement types. However, the profile of prohibited substances in manufactured and compounded dietary supplements (MDS and CDS, respectively) were distinct, with stimulants being most prevalent in MDS and anabolic agents in CDS products. Additionally, MDS samples generally presented higher estimated concentrations of banned substances (mg/g) than CDS samples (µg/g). The common practice of DS intake by athletes continues to be of great concern for a doping-free sport, given the high prevalence of prohibited substances detected in the analyzed samples by the LBCD. The current Brazilian scenario reinforces the importance of raising awareness in the sports community of the possible consequences of an unintentional doping case linked to DS use.

Pediatric Complex Regional Pain Syndrome and Occupational Therapy Intervention: A Scoping Review.

Complex regional pain syndrome (CRPS) is an increasingly recognized pain condition in the pediatric population. Occupational therapy (OT) is a crucial component of a multidisciplinary approach to treating pediatric CRPS. Yet, there is limited evidence detailing these OT interventions. This review aimed to explore the existing literature on OT interventions and delivery methods for pediatric CRPS. We performed a scoping review of peer-reviewed articles that included pediatric participants with CRPS with no limitation on publication date. Most of the 11 included studies described OT interventions that addressed pain, functional disability, motor and sensory function, social participation, and psychological well-being. Interventions included sensory reeducation programs, exercises, functional use of affected extremities, psychoeducation, and client and family education. To facilitate engagement in meaningful occupations, OT practitioners treating pediatric CRPS should provide evidence-based interventions and age-appropriate client education and include caregivers in the care plan.

Complex regional pain syndrome (CRPS) is a type of chronic pain that can affect not only adults, but kids and adolescents as well. Occupational therapy (OT) is an important part of helping kids with CRPS, but there is limited evidence describing OT interventions. This article reviewed all the available literature on OT interventions and delivery methods for kids and adolescents with CRPS. We found 11 articles, most of which described OT interventions that focused on treating pain, functional disability, motor and sensory function, social participation, and psychological well-being. Specific interventions included using the affected limb for everyday tasks, sensory re-education programs, exercises, education on dealing with the psychological impact of CRPS, and education for the child and family members. Findings emphasize that OT practitioners should provide evidence-based interventions and age-appropriate education and include caregivers in the plan of care to support engagement in meaningful occupations.

The Monarch Initiative in 2024: an analytic platform integrating phenotypes, genes and diseases across species.

Bridging the gap between genetic variations, environmental determinants, and phenotypic outcomes is critical for supporting clinical diagnosis and understanding mechanisms of diseases. It requires integrating open data at a global scale. The Monarch Initiative advances these goals by developing open ontologies, semantic data models, and knowledge graphs for translational research. The Monarch App is an integrated platform combining data about genes, phenotypes, and diseases across species. Monarch's APIs enable access to carefully curated datasets and advanced analysis tools that support the understanding and diagnosis of disease for diverse applications such as variant prioritization, deep phenotyping, and patient profile-matching. We have migrated our system into a scalable, cloud-based infrastructure; simplified Monarch's data ingestion and knowledge graph integration systems; enhanced data mapping and integration standards; and developed a new user interface with novel search and graph navigation features. Furthermore, we advanced Monarch's analytic tools by developing a customized plugin for OpenAI's ChatGPT to increase the reliability of its responses about phenotypic data, allowing us to interrogate the knowledge in the Monarch graph using state-of-the-art Large Language Models. The resources of the Monarch Initiative can be found at monarchinitiative.org and its corresponding code repository at github.com/monarch-initiative/monarch-app.

The role of community paramedicine in fall prevention: A SWOT analysis.

BACKGROUND: Millions of older US adults fall annually, leading to catastrophic injuries, over 32,000 deaths and healthcare costs of over $55 billion. This study evaluated perceived benefits and limitations of using community paramedicine for fall prevention strategies from the lens of older adults, caregivers, and healthcare providers. METHODS: Semi-structured focus groups were held with individuals from three stakeholder groups: (1) community-dwelling older adults (age ≥60), (2) caregivers, and (3) healthcare providers. The Strengths-Weaknesses-Opportunities-Threats (SWOT) framework was used to quantitatively analyze stakeholder perceptions of using community paramedicine for fall prevention strategies. RESULTS: A total of 10 focus groups were held with 56 participants representing older adults (n = 15), caregivers (n = 16), and healthcare providers (n = 25). Community paramedicine was supported as a model of fall prevention by older adults, caregivers, and healthcare providers. Participants identified strengths such as visibility to the home environment, ability to implement home modifications, implicit trust in emergency medical services (EMS), and capacity to redirect resources toward prevention. Additionally, participants acknowledged opportunities such as providing continuity of care across the healthcare spectrum, improving quality and safety of care and potentially reducing unnecessary emergency department use. Participants endorsed weaknesses and threats such as funding, concerns of patients about stigma, and struggles with medical data integration. CONCLUSIONS: The results of this study illuminate the opportunity to leverage community paramedicine to address a variety of perceived barriers in order to design and implement better solutions for fall prevention efforts.

Promotion of Successful Weight Management in Overweight and Obese Veterans (POWER-VET): Trial Design and Methods.

BACKGROUND: Almost 75% of US adults are overweight or obese. Though intentional weight loss of as little as 3% improves physical functioning and reduces cardiometabolic risk, most adults are unsuccessful at long-term weight maintenance. Our hypothesis is that intermittent fasting (IF: short periods of intense energy restriction) will reduce weight regain. IF may combat obesity due to its effects on nutrient-sensing signaling pathways and circadian rhythm. The objective of this randomized clinical trial is to test the effectiveness of an intensive body weight management program with and without IF. METHODS: In the Promotion of Successful Weight Management in Overweight and Obese Veterans (POWER-VET) trial (NCT04131647), 154 middle-aged and older adults (50-75 years) who are overweight and obese (BMI: 25-40 kg/m2) and seen at either a Baltimore, MD or San Antonio, TX Veterans Affairs Medical Center will be enrolled. Participants will undergo 12 weeks of weight loss (including a low-calorie heart healthy (HH) diet and exercise). Following weight loss, participants will be randomly assigned to one of two 24-week weight maintenance (WM) interventions: WM alone (continuation of HH diet and exercise) or WM + IF. The primary aim is to determine the effect of WM + IF compared to WM alone on body weight maintenance after intentional weight loss. DISCUSSION: Determining effective, translatable strategies that minimize weight regain following successful weight loss holds public health relevance. This POWER-VET trial introduces an innovative practice of IF to prevent weight regain after clinically significant weight reduction and could provide evidence-based recommendations to promote this type of intervention in middle aged and older adults.

BOSC 2023, the 24th annual Bioinformatics Open Source Conference.

The 24th annual Bioinformatics Open Source Conference ( BOSC 2023) was part of the 2023i conference on Intelligent Systems for Molecular Biology and the European Conference on Computational Biology (ISMB/ECCB 2023). Launched in 2000 and held yearly since, BOSC is the premier meeting covering open-source bioinformatics and open science. Like ISMB 2022, the 2023 meeting was a hybrid conference, with the in-person component hosted in Lyon, France. ISMB/ECCB attracted a near-record number of attendees, with over 2100 in person and about 900 more online. Approximately 200 people participated in BOSC sessions. In addition to 43 talks and 49 posters, BOSC featured two keynotes: Sara El-Gebali, who spoke about "A New Odyssey: Pioneering the Future of Scientific Progress Through Open Collaboration", and Joseph Yracheta, who spoke about "The Dissonance between Scientific Altruism & Capitalist Extraction: The Zero Trust and Federated Data Sovereignty Solution." Once again, a joint session brought together BOSC and the Bio-Ontologies COSI. The conference ended with a panel on Open and Ethical Data Sharing. As in prior years, BOSC was preceded by a CollaborationFest, a collaborative work event that brought together about 40 participants interested in synergistically combining ideas, shaping project plans, developing software, and more.
