Influences of Outdoor Experiences During Childhood on Time Spent in Nature as an Adult.

Introduction: Time spent in nature provides myriad physical and mental health benefits for both adults and children. Despite these benefits, most people spend too little time in nature to realize the maximal effect. Different types of childhood experiences may have differential influence on adult time in nature. This study assessed the influences of different kinds of childhood outdoor experiences on time spent in nature as an adult. The first aim was to utilize 20 childhood nature experience items to construct summative scales. The second aim was to examine the influence of each scale and other factors on adult time in nature. Methods: A 2-factor scale measuring wild and domesticated childhood nature experiences was developed using principal and confirmatory factor analyses. An online study of 2,109 American adults was conducted. Multiple linear regression examined the influences of the 2 childhood nature experiences scales, attitude and self-efficacy scales, and sex and age covariates on adult time spent in nature. Results: Significant predictors of adult time in nature were wild childhood nature experiences (ß=0.279, p<0.001), positive attitudes about nature (ß=0.12, p<0.05), negative attitudes about nature (ß= -0.23, p<0.001), and self-efficacy (ß=0.71, p<0.001). Conclusions: Wild childhood nature experiences (e.g., camping, hiking, and fishing) that include skill building, that are immersive and engaging, and that involve opportunity for social interaction may translate better into adult nature activities. Programs that introduce and support wild experiences may increase lifelong time spent in nature.

A Titanium-Based Metal-Organic Framework For Tandem Metallaphotocatalysis.

Metal-organic frameworks (MOFs) have garnered substantial attention for their unique properties, such as high porosity and tunable structures, making them versatile for various applications. This paper constructs photoactive titanium-organic frameworks by combining Ti(IV) clusters and a bipyridine linker. The MOF is synthesized in situ through imine condensation, resulting in NU-2300. Subsequent ex situ nickel salt complexation results in NU-2300-Ni, which is then used for light-mediated carbon-heteroatom cross-couplings. The photophysical properties of the metallaphotocatalyst were investigated by UV-vis and EPR analyses, and both the Ti cluster and the bipyridine linker were found to contribute to successful catalysis, making it a tandem catalyst. The heterogeneous material retained its performance through five cycles of thioetherification. This work contributes not only to MOF synthetic strategies but also to expanding MOF applications as recyclable, tandem metallaphotocatalysts.

Assessing effects of Cannabis on various neuropathologies: A systematic review.

Natural bioactives possess a wide range of chemical structures that can exert a plethora of pharmacological and toxicological actions, resulting in neuroprotection or neurotoxicity. These pharmacodynamic properties can positively or negatively impact human and animal global healthcare. Remarkably, Ayurvedic botanical Cannabis has been used worldwide by different ethnicities and religions for spiritual, commercial, recreational, nutraceutical, cosmeceutical, and medicinal purposes for centuries. Cannabis-based congeners have been approved by the United States of America's (USA) Food & Drug Administration (FDA) and other global law agencies for various therapeutic purposes. Surprisingly, the strict laws associated with possessing cannabis products have been mitigated in multiple states in the USA and across the globe for recreational use. This has consequently led to a radical escalation of exposure to cannabis-related substances of abuse. However, there is a lacuna in the literature on the acute and chronic effects of Cannabis and its congeners on various neuropathologies. Moreover, in the post-COVID era, there has been a drastic increase in the incidence and prevalence of numerous neuropathologies, leading to increased morbidity and mortality. There is an impending necessity for a safe, economically viable, multipotent, natural bioactive to prevent and treat various neuropathologies. The ayurvedic herb, Cannabis is one of the oldest botanicals known to humans and has been widely used. However, the comprehensive effect of Cannabis on various neuropathologies is not well established. Hence, this review presents effects of Cannabis on various neuropathologies.

Expert Consensus on Pediatric Urodynamics Reporting Using Modified Delphi Technique.

PURPOSE: Urodynamic testing (UDS) is an important tool in the management of pediatric lower urinary tract conditions. There have been notable efforts to standardize pediatric UDS nomenclature and technique, but no formal guidelines exist on essential elements to include in a clinical report. We sought to identify ideal structure and elements of a pediatric UDS assessment based on expert consensus. MATERIALS AND METHODS: Pediatric urologists regularly performing UDS were queried using a Delphi process. Participants were invited representing varied geographic, experience, and societal involvement. Participants underwent 3 rounds of questionnaires between November 2022 and August 2023 focusing on report organization, elements, definitions, and automated electronic health record clinical decision support. Professional billing requirements were also considered. Consensus was defined as 80% agreeing either in favor of or against a topic. Elements without consensus were discussed in subsequent rounds. RESULTS: A diverse sample of 30 providers, representing 27 institutions across 21 US states; Washington, District of Columbia; and Canada completed the study. Participants reported interpreting an average number of 5 UDS reports per week (range 1-22). The finalized consensus report identifies 93 elements that should be included in a pediatric UDS report based on applicable study conditions and findings. CONCLUSIONS: This consensus report details the key elements and structure agreed upon by an expert panel of pediatric urologists. Further standardization of documentation should aid collaboration and research for patients undergoing UDS. Based on this information, development of a standardized UDS report template using electronic health record implementation principles is underway, which will be openly available for pediatric urologists.

Unlocking the future of patient Education: ChatGPT vs. LexiComp® as sources of patient education materials.

BACKGROUND: ChatGPT is a conversational artificial intelligence technology that has shown application in various facets of healthcare. With the increased use of AI, it is imperative to assess the accuracy and comprehensibility of AI platforms. OBJECTIVE: This pilot project aimed to assess the understandability, readability, and accuracy of ChatGPT as a source of medication-related patient education as compared with an evidence-based medicine tertiary reference resource, LexiComp®. METHODS: Patient education materials (PEMs) were obtained from ChatGPT and LexiComp® for 8 common medications (albuterol, apixaban, atorvastatin, hydrocodone/acetaminophen, insulin glargine, levofloxacin, omeprazole, and sacubitril/valsartan). PEMs were extracted, blinded, and assessed by 2 investigators independently. The primary outcome was a comparison of the Patient Education Materials Assessment Tool-printable (PEMAT-P). Secondary outcomes included Flesch reading ease, Flesch Kincaid grade level, percent passive sentences, word count, and accuracy. A 7-item accuracy checklist for each medication was generated by expert consensus among pharmacist investigators, with LexiComp® PEMs serving as the control. PEMAT-P interrater reliability was determined via intraclass correlation coefficient (ICC). Flesch reading ease, Flesch Kincaid grade level, percent passive sentences, and word count were calculated by Microsoft® Word®. Continuous data were assessed using the Student's t-test via SPSS (version 20.0). RESULTS: No difference was found in the PEMAT-P understandability score of PEMs produced by ChatGPT versus LexiComp® [77.9% (11.0) vs. 72.5% (2.4), P=0.193]. Reading level was higher with ChatGPT [8.6 (1.2) vs. 5.6 (0.3), P < 0.001). ChatGPT PEMs had a lower percentage of passive sentences and lower word count. The average accuracy score of ChatGPT PEMs was 4.25/7 (61%), with scores ranging from 29% to 86%. CONCLUSION: Despite comparable PEMAT-P scores, ChatGPT PEMs did not meet grade level targets. Lower word count and passive text with ChatGPT PEMs could benefit patients, but the variable accuracy scores prevent routine use of ChatGPT to produce medication-related PEMs at this time.

Racism-related stress and mental health among black women living in Los Angeles County, California: A comparison of postpartum mood and anxiety disorder screening scales.

PURPOSE: To assess Black women's exposure to and appraisal of racism-related stress during the postpartum period and to distinguish its impact on three indicators of postpartum mood and anxiety disorders (PMADs) symptoms. METHODS: Data from the Black Mothers' Mental Wellness Study (N = 231) and linear regression models estimated the associations between racism-related stress and the PMAD indicators: 3-item Edinburgh Postnatal Depression Scale (EPDS-3), 8-item Patient Health Questionnaire (PHQ-8), and PHQ-15. RESULTS: The majority of participants (80.5%, N = 186) experienced racism a few times a year or more, of which 37.1% (N = 69) were bothered somewhat and 19.3% (N = 36) a lot. Racism-related stress, income, level of education, and history of mental health diagnosis explained greater variance in PMAD symptoms as measured by the PHQ-8 score (R2 = 0.58, p = < 0.001) compared to the EPDS-3 (R2 = 0.46, p = < 0.001) or the PHQ-15 (R2 = 0.14, p = 0.035). CONCLUSIONS: Racism is a stressor for Black women living in Los Angeles County, California. Racism-related stress and emotional expression of PMAD symptoms were salient to the postpartum mental health of the Black women in this study. Findings from this study suggest that the PHQ-8 should be used to assess how racism impacts Black women's postpartum mental health.

Novel forms of ventilation in neonates: Neurally adjusted ventilatory assist and proportional assist ventilation.

Patient-triggered modes of ventilation are currently the standard of practice in the care of term and preterm infants. Maintaining spontaneous breathing during mechanical ventilation promotes earlier weaning and possibly reduces ventilator-induced diaphragmatic dysfunction. A further development of assisted ventilation provides support in proportion to the respiratory effort and enables the patient to have full control of their ventilatory cycle. In this paper we will review the literature on two of these modes of ventilation: neurally adjusted ventilatory assist (NAVA) and proportional assist ventilation (PAV), propose future studies and suggest clinical applications of these modes.

Quantity and quality are increasing but there's room for improvement: A scoping review of physical activity intervention trials.

BACKGROUND: Observing trends in research publications helps to identify the quantity and quality of research produced, as well as reveal evidence gaps. No comprehensive review of the quality and quantity of physical activity intervention trials has been conducted. OBJECTIVE: We aimed to investigate i) the volume and quality (and changes in these over time) of randomized controlled trials evaluating physical activity interventions, and ii) the association between journal ranking and trial quality. METHODS: We searched the Physiotherapy Evidence Database (PEDro) for trials investigating physical activity interventions (no restrictions for population, comparison, or language). Descriptive statistics were used to describe the volume and quality of trials. The association between journal ranking (Journal Impact Factor) and trial quality (PEDro Scale) was examined using Spearman's rho correlation. RESULTS: We identified 1779 trials, of which 40% (n = 710) were published between 2016 and 2020. The mean (SD) total PEDro score was 5.3 (1.5) points out of 10, increasing over time from 2.5 (0.7) points in 1975-1980 to 5.6 (1.4) points in 2016-2020. Quality criteria that were least reported included blinding of intervention deliverers (therapists) (n = 3, 0.2%), participants (n = 21, 1.2%), or assessors (n = 541, 31%); concealed allocation to groups (n = 526, 30%); and intention to treat analysis (n = 764, 43%). There was a small correlation between trial quality and Journal Impact Factor (0.21, p < 0.001). CONCLUSION: A large volume of trials has investigated physical activity interventions. The quality of these trial reports is suboptimal but improving over time. Journal ranking should not be used for selecting high quality trials.

Trace metal transfer to passerines inhabiting wastewater treatment wetlands.

Wastewater treatment wetlands are cost-effective strategies for remediating trace metals in industrial effluent. However, biogeochemical exchange between wastewater treatment wetlands and adjacent environments provides opportunities for trace metals to cycle in surrounding ecosystems. The transfer of trace metals to wildlife inhabiting treatment wetlands must be considered when evaluating wetland success. Using passerine birds as bioindicators, we conducted a multi-tissue analysis to investigate the mobilization of zinc, copper, and lead derived from wastewater to terrestrial wildlife in treatment wetlands and surrounding habitat. In addition, we evaluate the strength of relationships between metal concentrations in non-lethal (blood and feathers) and lethal (muscle and liver) sample types for estimation of toxicity risk. From July 2020 to August 2021, 177 passerines of seven species were captured at two wetlands constructed to treat industrial wastewater and two reference wetlands in the coastal plain of South Carolina. Feather, blood, liver, and muscle samples from each bird were analyzed for fourteen metals using inductively coupled plasma mass spectrometry and direct mercury analysis. Passerines inhabiting wastewater treatment wetlands accumulated higher concentrations of zinc in liver, copper in blood, and lead in feathers than passerines in reference wetlands, but neither blood nor feather concentrations were correlated with internal tissue concentrations. Of all the detected metals, only mercury in the blood showed a strong predictive relationship with mercury in internal tissues. This study indicates that trace metals derived from wastewater are bioavailable and exported to terrestrial wildlife and that passerine biomonitoring is a valuable tool for assessing metal transfer from treatment wetlands. Regular blood sampling can reveal proximate trace metal exposure but cannot predict internal body burdens for most metals.

Necessary, burdensome, or threatening? Awareness of Black-White disparities in health care access and self-rated health for Black and White Americans.

Awareness of racial health care inequities is one prerequisite to eliminating them. Although extant research has described awareness of racial health care inequities in the United States, the health impacts of such awareness on communities that are most impacted by these inequities remains unknown. Therefore, we examined associations between awareness of Black-White racial health care inequities and self-rated health for Black and White adults in the United States. We used survey data from non-Hispanic Black and White participants (N = 6,449) who responded to the national American Health Values Survey (2015-2016) to test associations between awareness of Black-White inequities in health care and self-rated health. Accurate awareness of health care inequities was associated with 47% higher odds of poorer self-rated health for Black individuals. Inaccurate awareness was associated with 36% higher odds of poorer self-rated health for White individuals. Accurate awareness may be adaptive, yet place an additional burden on Black individuals. Inaccurate awareness may harm White individuals' health. Health care system changes and alleviation of racism-related stress may be preventive supports for the health of Black individuals. Accurate awareness should be a goal for White individuals, not only to prevent health risks, but to also facilitate structural change for racial equity.

Multi-Factor Coral Disease Risk: A new product for early warning and management.

Ecological forecasts are becoming increasingly valuable tools for conservation and management. However, there are few examples of near-real-time forecasting systems that account for the wide range of ecological complexities. We developed a new coral disease ecological forecasting system that explores a suite of ecological relationships and their uncertainty and investigates how forecast skill changes with shorter lead times. The Multi-Factor Coral Disease Risk product introduced here uses a combination of ecological and marine environmental conditions to predict the risk of white syndromes and growth anomalies across reefs in the central and western Pacific and along the east coast of Australia and is available through the US National Oceanic and Atmospheric Administration Coral Reef Watch program. This product produces weekly forecasts for a moving window of 6 months at a resolution of ~5 km based on quantile regression forests. The forecasts show superior skill at predicting disease risk on withheld survey data from 2012 to 2020 compared with predecessor forecast systems, with the biggest improvements shown for predicting disease risk at mid- to high-disease levels. Most of the prediction uncertainty arises from model uncertainty, so prediction accuracy and precision do not improve substantially with shorter lead times. This result arises because many predictor variables cannot be accurately forecasted, which is a common challenge across ecosystems. Weekly forecasts and scenarios can be explored through an online decision support tool and data explorer, co-developed with end-user groups to improve use and understanding of ecological forecasts. The models provide near-real-time disease risk assessments and allow users to refine predictions and assess intervention scenarios. This work advances the field of ecological forecasting with real-world complexities and, in doing so, better supports near-term decision making for coral reef ecosystem managers and stakeholders. Secondarily, we identify clear needs and provide recommendations to further enhance our ability to forecast coral disease risk.

A survey on awareness, knowledge and preferences toward genetic testing among the United States general public.

Aim: To understand awareness, knowledge and preferences regarding genetic testing among the USA general public. Methods: A cross-sectional online survey using a Qualtrics Panel. Results: Among 1600 respondents, 545 (34%) were White, 411 (26%) Black, 412 (26%) Hispanic or Latin(x) and 232 (15%) Asian. Most had heard of ancestry testing (87%) and genetic health risk testing (69%), but a third thought inherited genes were only a little or not at all responsible for obesity (36%) and mental health (33%). The majority preferred pre-emptive pharmacogenetic testing (n = 74%) compared with reactive testing. Statistically significant differences between racial/ethnic groups and rural-urban respondents were observed. Conclusion: Most preferred pre-emptive pharmacogenetic testing; however, about one-quarter preferred reactive testing. Preferences should be discussed during patient-clinician interactions.

What is this study about? This study presents a large online survey among the USA general public to understand their awareness, knowledge and preferences about genetic testing and how this may vary by racial/ethnic group and rural/urban status.What were the results? Most survey respondents had heard of ancestry testing (87%) and genetic health risk testing (69%). However, over a third of respondents thought that inherited genes may be only a little or not at all responsible for obesity (36%) and mental health (33%). When asked about preferences for pre-emptive compared with reactive pharmacogenetic testing, the majority preferred pre-emptive testing (n = 74%). Statistically significant differences between racial/ethnic groups as well as rural-urban respondents were seen.What do the results mean? The US general public may have a different understanding of genetic testing for different diseases, and have different preferences when it comes to the timing of testing. Appropriate educational content targeting the link between genetics and specific diseases should be prepared, and preferences for pre-emptive or reactive testing should be discussed during visits with healthcare providers.

The Influence of Kynurenine Metabolites on Neurodegenerative Pathologies.

As the kynurenine pathway's links to inflammation, the immune system, and neurological disorders became more apparent, it attracted more and more attention. It is the main pathway through which the liver breaks down Tryptophan and the initial step in the creation of nicotinamide adenine dinucleotide (NAD+) in mammals. Immune system activation and the buildup of potentially neurotoxic substances can result from the dysregulation or overactivation of this pathway. Therefore, it is not shocking that kynurenines have been linked to neurological conditions (Depression, Parkinson's, Alzheimer's, Huntington's Disease, Schizophrenia, and cognitive deficits) in relation to inflammation. Nevertheless, preclinical research has demonstrated that kynurenines are essential components of the behavioral analogs of depression and schizophrenia-like cognitive deficits in addition to mediators associated with neurological pathologies due to their neuromodulatory qualities. Neurodegenerative diseases have been extensively associated with neuroactive metabolites of the kynurenine pathway (KP) of tryptophan breakdown. In addition to being a necessary amino acid for protein synthesis, Tryptophan is also transformed into the important neurotransmitters tryptamine and serotonin in higher eukaryotes. In this article, a summary of the KP, its function in neurodegeneration, and the approaches being used currently to target the route therapeutically are discussed.

Ceftriaxone alters the gut microbiome composition and reduces alcohol intake in male and female Sprague-Dawley rats.

Ceftriaxone is an antibiotic that increases central nervous system (CNS) protein expression of the glutamate transporters GLT-1 and xCT and ameliorates pathological behaviors in rodent models of neurological disease and substance use disorder. However, little ceftriaxone passes through the blood-brain-barrier, the CNS binding partner of ceftriaxone is unknown, and ceftriaxone does not consistently upregulate GLT-1 and xCT in cell culture. Ceftriaxone alters the gut microbiome composition in rodents and humans, and the microbiome-gut-brain axis regulates drug-seeking. Thus, here we test the hypothesis that ceftriaxone reduces alcohol intake while ameliorating alcohol-induced disruption of the gut microbiome composition. Male and female Sprague-Dawley rats received intermittent access to alcohol (IAA) while controls received access to only water. Following 17 IAA sessions, ceftriaxone/vehicle treatment was given for 5 days. Analysis of the gut microbiome composition was assessed by 16S rRNA gene amplicon sequencing conducted on fecal pellets collected prior to and after alcohol consumption and following ceftriaxone treatment. Male rats displayed escalated alcohol intake and preference over the course of the 17 sessions; however, total alcohol intake did not differ between the sexes. Ceftriaxone reduced alcohol intake and preference in male and female rats. While alcohol affected a diverse set of amplicon sequencing variants (ASV), ceftriaxone markedly reduced the diversity of microbial communities reflected by a blooming of the Enterococcaceae family. The remaining effects of ceftriaxone, however, encompassed families both affected and unaffected by prior alcohol drinking and highlight the Ruminococcaceae and Muribaculaceae families as bidirectionally modulated by alcohol and ceftriaxone. Altogether, our study confirms that ceftriaxone reduces alcohol intake in rats and partially reverses alcohol-induced dysbiosis.

Voluntary alcohol intake alters the motivation to seek intravenous oxycodone and neuronal activation during the reinstatement of oxycodone and sucrose seeking.

Opioid-alcohol polysubstance use is prevalent and worsens treatment outcomes. Here we assessed whether co-consumption of oxycodone and alcohol influence the intake of one another, demand for oxycodone, and the neurocircuitry underlying cue-primed reinstatement of oxycodone-seeking. Male and female rats underwent oxycodone intravenous self-administration (IVSA) with homecage access to alcohol (20% v/v) and/or water immediately after the IVSA session. Next, economic demand for intravenous oxycodone was assessed while access to alcohol and/or water continued. Control rats self-administered sucrose followed by access to alcohol and/or water. Rats underwent a cue-primed reinstatement test and brains were processed for c-fos mRNA expression. While both sexes decreased oxycodone intake if they had access to alcohol, and decreased alcohol intake if they had access to oxycodone, only female oxycodone + alcohol rats exhibited decreased demand elasticity and increased cue-primed reinstatement. Alcohol consumption increased the number of basolateral and central amygdala neurons activated during sucrose and oxycodone reinstatement and the number of ventral and dorsal striatum neurons engaged by sucrose reinstatement. Nucleus accumbens shell dopamine 1 receptor expressing neurons displayed activation patterns consistent with oxycodone reinstatement. Thus, alcohol alters the motivation to seek oxycodone in a sex-dependent manner and the neural circuitry engaged by cue-primed reinstatement of sucrose and oxycodone-seeking.

Listening to the Data: Computational Approaches to Addiction and Learning.

Computational approaches hold great promise for identifying novel treatment targets and creating translational therapeutics for substance use disorders. From circuitries underlying decision-making to computationally derived neural markers of drug-cue reactivity, this review is a summary of the approaches to data presented at our 2023 Society for Neuroscience Mini-Symposium. Here, we highlight data- and hypothesis-driven computational approaches that recently afforded advancements in addiction and learning neuroscience. First, we discuss the value of hypothesis-driven algorithmic modeling approaches, which integrate behavioral, neural, and cognitive outputs to refine hypothesis testing. Then, we review the advantages of data-driven dimensionality reduction and machine learning methods for uncovering novel predictor variables and elucidating relationships in high-dimensional data. Overall, this review highlights recent breakthroughs in cognitive mapping, model-based analysis of behavior/risky decision-making, patterns of drug taking, relapse, and neuromarker discovery, and showcases the benefits of novel modeling techniques, across both preclinical and clinical data.

Direct Oral Anticoagulants: Probability of Recurrent Venous Thromboembolism and Bleeding Risk in an Obese Population.

BACKGROUND: Direct-acting oral anticoagulants (DOACs) have become the preferred drugs for managing venous thromboembolism (VTE). Despite their advantages over vitamin K antagonists such as warfarin, their use in obese patients remains controversial with many providers reluctant to switch patients managed on warfarin. Outcome research that opts to increase provider confidence when prescribing DOACs for patients with obesity will be invaluable. OBJECTIVE: This investigation evaluated whether patients with a body mass index (BMI) 35 kg/m2 or greater who were prescribed a DOAC had a higher risk for a recurrent VTE or bleed event relative to warfarin. METHODS: The study was conducted in West Virginia which has the highest rate of obesity in the United States. RESULTS: Of the total study population (1633), 2.3% (37) had a recurrent thrombotic event, 5.5% (89) had a major bleed event, and 10.7% (174) had some type of bleeding event. No individual patient characteristic was associated with recurrent thrombosis-including BMI. Older age, antiplatelet use, and taking a medication with a theoretical risk of increasing the effect of DOACs were associated with any and major bleeding events. The use of warfarin was associated with major bleeding events more frequently versus a DOAC. Body mass index was not a predictor for recurrent VTE or any bleed or major bleed events. CONCLUSIONS: These findings support the conclusion that DOACs are an appropriate and effective drug class for the management of VTE in patients with obesity.

Rural Appalachian Women Will Suffer Disproportionately if Attempts to Further Restrict Emergency Contraception are Successful.

The removal of federal abortion protection has incited fear that restrictions on contraception may be next. Many states now imposing abortion restrictions and bans are in the South and Appalachian Regions of the U.S., where rates of unplanned pregnancy and poor health outcomes are already disproportionately high. Numerous studies have documented variable access to levonorgestrel EC (LNG EC) in community pharmacies, with particularly low rates of access at independent pharmacies that are more likely to be located in rural communities than chain pharmacies. Since the overturn of Roe v. Wade, some large chain pharmacies and online retailers are restricting the purchase of LNG EC, limiting its availability. Some legislators and activists are calling for a ban on EC based on a misunderstanding about its mechanism of action, equating it with abortion. At a time when access to the full range of contraceptive options is more critical than ever, already limited access to LNG EC is worsening. Extensive data on LNG EC availability in 509 pharmacies and 400 health clinics across West Virginia, contextualized with socioeconomic demographics, illustrate existing disparities in LNG EC access.
