RESUMO

Body size is an important species trait, correlating with life span, fecundity, and other ecological factors. Over Earth's geological history, climate shifts have occurred, potentially shaping body size evolution in many clades. General rules attempting to summarize body size evolution include Bergmann's rule, which states that species reach larger sizes in cooler environments and smaller sizes in warmer environments, and Cope's rule, which poses that lineages tend to increase in size over evolutionary time. Tetraodontiform fishes (including pufferfishes, boxfishes, and ocean sunfishes) provide an extraordinary clade to test these rules in ectotherms owing to their exemplary fossil record and the great disparity in body size observed among extant and fossil species. We examined Bergmann's and Cope's rules in this group by combining phylogenomic data (1,103 exon loci from 185 extant species) with 210 anatomical characters coded from both fossil and extant species. We aggregated data layers on paleoclimate and body size from the species examined, and inferred a set of time-calibrated phylogenies using tip-dating approaches for downstream comparative analyses of body size evolution by implementing models that incorporate paleoclimatic information. We found strong support for a temperature-driven model in which increasing body size over time is correlated with decreasing oceanic temperatures. On average, extant tetraodontiforms are two to three times larger than their fossil counterparts, which otherwise evolved during periods of warmer ocean temperatures. These results provide strong support for both Bergmann's and Cope's rules, trends that are less studied in marine fishes compared to terrestrial vertebrates and marine invertebrates.

RESUMO

INTRODUCTION: There are few disease-specific patient-reported outcome measures (PROMs) for use in pediatric limb deformity (LD), with authors instead relying on generic PROMs such as the Pediatric Outcomes Data Collection Instrument (PODCI) to assess treatment outcomes from the patient's perspective. The purpose of this study was to perform preliminary validation of 2 disease-specific PROMs in pediatric patients with LD. METHODS: LD modifications were created by substituting the word "limb" for "back" in the Early Onset Scoliosis Questionnaire (EOSQ, ages 10 and younger) and the Scoliosis Research Society (SRS, ages 11 to 18) survey, creating the LD-EOSQ and LD-SRS instruments. Children were preoperatively administered the age-appropriate LD-PROMs (n=34 LD-EOSQ; n=30 LD-SRS) and PODCI questionnaires. LD-PROMs were assessed for construct (convergent and discriminant) validity, floor and ceiling effects, content validity, and minimal clinically important difference. RESULTS: Both LD-EOSQ and LD-SRS demonstrated excellent preliminary convergent validity with similar PODCI domains and discriminant validity with demographic information, deformity data, and LLRS-AIM scores. There were minimal floor or ceiling effects. Content validity was achieved in 100% of LD-EOSQ surveys and more than 80% of LD-SRS surveys. Minimal clinically important difference was 0.4 for LD-EOSQ and 0.3 for LD-SRS. CONCLUSIONS: The LD-EOSQ for patients aged 10 and under and LD-SRS for patients aged 11 to 18 demonstrated preliminary validity and reliability in the pediatric LD population. These measures provide more information specifically related to familial impact in younger children and self-image and mental health in adolescents compared to the PODCI and should be further evaluated for use in these patients. LEVEL OF EVIDENCE: Level II-diagnostic. Prospective cross-sectional cohort design.

RESUMO

BACKGROUND: To retrospectively evaluate the clinical outcomes of patients treated for syndesmotic injuries with an all-suture construct technique and compare their patient reported outcome scores with historically published outcomes of syndesmotic injuries fixed with suspensory suture buttons. METHODS: This was a retrospective case series of patients treated at a Level 1 Trauma Center from May 1, 2018, to June 30, 2022. Ten patients aged 18 and older with unstable syndesmotic injuries treated with all-suture repair. Patients were excluded if they were treated with trans-osseous screws, had previous failed syndesmotic fixation, or suspensory suture button fixation. Patient-reported outcomes including Visual Analog Scale (VAS) pain scores, American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scores, and complications were recorded. RESULTS: In the patients with 6 weeks or more of radiographic follow-up (N = 9), there was no evidence of nonunion, loss of fixation, hardware complication, or whitling of the fibula by the suture. At final follow-up average VAS pain scores were 1.5 out of 10 (range 0-4; SD 1.2), AOFAS ankle and hindfoot scores averaged 89.6 out of 100 (range 86-100; SD 6.1). The pain subscale of the AOFAS score averaged 37.5 out of 40 (range 35-40; SD 2.5). The functional subscale of the AOFAS score averaged 46 out of 50 (range 44-50; SD 3.0). Stiffness was reported in one patient at their follow-up visits, which resolved with continued physical therapy. There were no superficial or deep infections. CONCLUSIONS: In conclusion, this case series presents the first clinical outcomes of an all-suture fixation technique for treatment of unstable syndesmotic ankle injuries. Our results suggest that the all-suture fixation technique results in similar patient reported outcomes when compared with historically reported patient reported outcomes of suspensory suture button fixation, and low rates of complication or hardware failure.

RESUMO

In vivoimaging of protein complexes is a powerful method for understanding the underlying biological function of these key biomolecules. Though the engineering of small, high affinity nanobodies have become more prevalent, the off-rates of these tags may result in incomplete or partial labeling of proteins in live cells. The SpyCatcher003 and SpyTag split protein system allow for irreversible, covalent binding to a short target peptide unlike nanobody-affinity based probes. However, delivering these tags into a cell without disrupting its normal function is a key challenge. Cell penetrating peptides (CPPs) are short peptide sequences that facilitate the transduction of otherwise membrane-impermeable 'cargo' , such as proteins, into cells. Here we report on our efforts to engineer and characterize CPP-SpyCatcher003 fusions as modular imaging probes. We selected three CPPs, CUPID, Pentratin, and pVEC, to engineer fusion protein probes for superresolution microscopy, with the aim to eliminate prior permeabilization treatments that could introduce imaging artifacts. We find that fusing the CPP sequences to SpyCatcher003 resulted in dimer and multimer formation as determined by size exclusion chromatography, dynamic light scattering, and SDS resistant dimers on SDS-PAGE gels. By isolating and labeling the monomeric forms of the engineered protein, we show these constructs retained their ability to bind SpyTag and all three CPP sequences remain membrane active, as assessed by CD spectroscopy in the presence of SDS detergent. Using fluorescence and super resolution Lattice structured illumination microscopy (Lattice SIM) imaging we show that the CPPs did not enhance uptake of SpyCatcher byE. coli,however withCaulobacter crescentuscells, we show that Penetratin, and to a lesser degree CUPID, does enhance uptake. Our results demonstrate the ability of the CPP-SpyCatcher003 to label targets within living cells, providing the groundwork for using split protein systems for targetedin vivoimaging.

RESUMO

BACKGROUND: TKA and THA are major surgical procedures, and they are associated with the potential for serious, even life-threatening complications. Patients must weigh the risks of these complications against the benefits of surgery. However, little is known about the relative importance patients place on the potential complications of surgery compared with any potential benefit the procedures may achieve. Furthermore, patient preferences may often be discordant with surgeon preferences regarding the treatment decision-making process. A discrete-choice experiment (DCE) is a quantitative survey technique designed to elicit patient preferences by presenting patients with two or more hypothetical scenarios. Each scenario is composed of several attributes or factors, and the relative extent to which respondents prioritize these attributes can be quantified to assess preferences when making a decision, such as whether to pursue lower extremity arthroplasty. QUESTIONS/PURPOSES: In this DCE, we asked: (1) Which patient-related factors (such as pain and functional level) and surgery-related factors (such as the risk of infection, revision, or death) are influential in patients' decisions about whether to undergo lower extremity arthroplasty? (2) Which of these factors do patients emphasize the most when making this decision? METHODS: A DCE was designed with the following attributes: pain; physical function; return to work; and infection risks, reoperation, implant failure leading to premature revision, deep vein thrombosis, and mortality. From October 2021 to March 2022, we recruited all new patients to two arthroplasty surgeons' clinics who were older than 18 years and scheduled for a consultation for knee- or hip-related complaints who had no previous history of a primary TKA or THA. A total of 56% (292 of 517) of new patients met the inclusion criteria and were approached with the opportunity to complete the DCE. Among the cohort, 51% (150 of 292) of patients completed the DCE. Patients were administered the DCE, which consisted of 10 hypothetical scenarios that had the patient decide between a surgical and nonsurgical outcome, each consisting of varying levels of eight attributes (such as infection, reoperation, and ability to return to work). A subsequent demographic questionnaire followed this assessment. To answer our first research question about the patient-related and surgery-related factors that most influence patients' decisions to undergo lower extremity arthroplasty, we used a conditional logit regression to control for potentially confounding attributes from within the DCE and determine which variables shifted a patient's determination to pursue surgery. To answer our second question, about which of these factors received the greatest priority by patients, we compared the relevant importance of each factor, as determined by each factor's beta coefficient, against each other influential factor. A larger absolute value of beta coefficient reflects a relatively higher degree of importance placed on a variable compared with other variables within our study. Of the respondents, 57% (85 of 150) were women, and the mean age at the time of participation was 64 ± 10 years. Most respondents (95% [143 of 150]) were White. Regarding surgery, 38% (57 of 150) were considering THA, 59% (88 of 150) were considering TKA, and 3% (5 of 150) were considering both. Among the cohort, 49% (74 of 150) of patients reported their average pain level as severe, or 7 to 10 on a scale from 0 to 10, and 47% (71 of 150) reported having 50% of full physical function. RESULTS: Variables that were influential to respondents when deciding on lower extremity total joint arthroplasty were improvement from severe pain to minimal pain (ß coefficient: -0.59 [95% CI -0.72 to -0.46]; p < 0.01), improvement in physical function level from 50% to 100% (ß: -0.80 [95% CI -0.9 to -0.7]; p < 0.01), ability to return to work versus inability to return (ß: -0.38 [95% CI -0.48 to -0.28]; p < 0.01), and the surgery-related factor of risk of infection (ß: -0.22 [95% CI -0.30 to -0.14]; p < 0.01). Improvement in physical function from 50% to 100% was the most important for patients making this decision because it had the largest absolute coefficient value of -0.80. To improve physical function from 50% to 100% and reduce pain from severe to minimal because of total joint arthroplasty, patients were willing to accept a hypothetical absolute (and not merely an incrementally increased) 37% and 27% risk of infection, respectively. When we stratified our analysis by respondents' preoperative pain levels, we identified that only patients with severe pain at the time of their appointment found the risk of infection influential in their decision-making process (ß: -0.27 [95% CI -0.37 to -0.17]; p = 0.01) and were willing to accept a 24% risk of infection to improve their physical functioning from 50% to 100%. CONCLUSION: Our study revealed that patients consider pain alleviation, physical function improvement, and infection risk to be the most important attributes when considering total joint arthroplasty. Patients with severe baseline pain demonstrated a willingness to take on a hypothetically high infection risk as a tradeoff for improved physical function or pain relief. Because patients seemed to prioritize postoperative physical function so highly in our study, it is especially important that surgeons customize their presentations about the likelihood an individual patient will achieve a substantial functional improvement as part of any office visit where arthroplasty is discussed. Future studies should focus on quantitatively assessing patients' understanding of surgical risks after a surgical consultation, especially in patients who may be the most risk tolerant. CLINICAL RELEVANCE: Surgeons should be aware that patients with the most limited physical function and the highest baseline pain levels are more willing to accept the more potentially life-threatening and devastating risks that accompany total joint arthroplasty, specifically infection. The degree to which patients seemed to undervalue the harms of infection (based on our knowledge and perception of those harms) suggests that surgeons need to take particular care in explaining the degree to which a prosthetic joint infection can harm or kill patients who develop one.

RESUMO

INTRODUCTION: At the Alzheimer's Association's APOE and Immunity virtual conference, held in October 2021, leading neuroscience experts shared recent research advances on and inspiring insights into the various roles that both the apolipoprotein E gene (APOE) and facets of immunity play in neurodegenerative diseases, including Alzheimer's disease and other dementias. METHODS: The meeting brought together more than 1200 registered attendees from 62 different countries, representing the realms of academia and industry. RESULTS: During the 4-day meeting, presenters illuminated aspects of the cross-talk between APOE and immunity, with a focus on the roles of microglia, triggering receptor expressed on myeloid cells 2 (TREM2), and components of inflammation (e.g., tumor necrosis factor α [TNFα]). DISCUSSION: This manuscript emphasizes the importance of diversity in current and future research and presents an integrated view of innate immune functions in Alzheimer's disease as well as related promising directions in drug development.

RESUMO

PURPOSE: Surgical trauma may confer additional infectious risk after operative fixation for high energy tibial plateau fractures. This study aims to determine the impact of plate number and location on infection rates after these injuries. METHODS: This retrospective cohort study completed at two level one trauma centers included patients who underwent staged fixation for a tibial plateau fracture between 2015 and 2019. Plate number and location (lateral, medial, posteromedial, and anterior quadrants) used in the definitive fixation construct were collected from post-operative radiographs. Deep infection rate was primary the outcome. RESULTS: A total of 244 patients met inclusion criteria. The overall infection rate was 13.9% (34/244). Infection rates increased with each additional quadrant utilized (8.0% one quadrant, 13.0% two quadrants, 27.3% three quadrants, 100% four quadrants; p < 0.001), independent of plate number, fracture severity, operative time, number of incisions, external fixator pin and plate construct overlap, and days in the external fixator on multivariate analysis. CONCLUSIONS: Infection risk increases with each quadrant utilized in the fixation of high energy tibial plateau fractures. Providers should attempt to limit the dissection of soft tissue for hardware placement in the fixation of these injuries to limit infection risk. LEVEL OF EVIDENCE: Level III, retrospective therapeutic study.

RESUMO

Teleost fishes perceive their environment through a range of sensory modalities, among which olfaction often plays an important role. Richness of the olfactory repertoire depends on the diversity of receptors coded by homologous genes classified into four families: OR, TAAR, VR1, and VR2. Herein, we focus on the OR gene repertoire. While independent large contractions of the OR gene repertoire associated with ecological transitions have been found in mammals, little is known about the diversity of the OR gene repertoire and its evolution in teleost fishes, a group that includes more than 34,000 living species. We analyzed genomes of 163 species representing diversity in this large group. We found a large range of variation in the number of functional OR genes, from 15 in the Broad-nose Pipefish Syngnathus typhle and the Ocean Sunfish Mola mola, to 429 in the Zig-zag Eel Mastacembelus armatus. The number of OR genes was higher in species when a multilamellar olfactory rosette was present. Moreover, the number of lamellae was correlated with the richness of the OR gene repertoire. While a slow and balanced birth-and-death process generally drives the evolution of the OR gene repertoire, we inferred several episodes of high rates of gene loss, sometimes followed by large gains in the number of OR genes. These gains coincide with morphological changes of the olfactory organ and suggest a strong functional association between changes in the morphology and the evolution of the OR gene repertoire.

RESUMO

The current studies examined the relationship between the penchant to daydream about helping others and prosocial traits and behaviour. We reasoned that fantasising about prosocial acts should be positively associated with a more prosocial disposition and real behaviour. Across both studies, the findings suggest that people who exhibit prosocial characteristics (e.g., empathic concern, fantasy/fictional empathy, moral reasoning) are more likely to fantasise about prosocial behaviour, and these characteristics are reliably associated with increased helping behaviours. From Study 1, the correlational results showed that people higher in agreeableness exhibited a stronger tendency to engage in prosocial fantasising, and empathy, in part, mediated the relationship. The experimental results from Study 2 conceptually support those from Study 1; when prompted to fantasise about prosocial behaviour, those higher in agreeableness and openness to experience engaged in more helping behaviour, whereas in a control condition, no helping differences emerged. Finding that empathic concern was most consistently related to daydreaming is consistent with the theory in that people are more intrinsically motivated to promote other's welfare at a personal cost when they feel empathy. Engaging in prosocial fantasising may increase empathy, which in turn, may enhance one's prosocial disposition and increase one's helping behaviour.

RESUMO

Ninety-six juvenile specimens (37-54 mm standard length; LS ) of the rarely collected Upward-Mouth Spikefish Atrophacanthus japonicus (Triacanthodidae) were obtained from the stomachs of three Yellowfin Tuna Thunnus albacares collected off Guam in the Mariana Islands in the central Pacific Ocean. These specimens extend the range of A. japonicus eastward into Oceania. We review the systematic characters of the monotypic genus Atrophacanthus and present colour photographs of freshly collected specimens. The diet of the juvenile specimens of A. japonicus consisted of thecosome pteropods and foraminiferans. We present a range map of A. japonicus based on all known specimens and show that specimen size is related to whether specimens were collected in the pelagic zone or on the bottom. Our results support that, compared to all other Triacanthodidae, A. japonicus has an unusually extended pelagic larval and juvenile period, up to 54 mm LS , before settling to the bottom as adults. Lastly, we provide a multilocus phylogeny addressing the phylogenetic placement of Atrophacanthus based on eight of 11 triacanthodid genera and six genetic markers. Our results reveal that Atrophacanthus is the sister group of Macrorhamphosodes and they provide new insights about the evolutionary history of the family.

RESUMO

Integrative evolutionary analyses based upon fossil and extant species provide a powerful approach for understanding past diversification events and for assessing the tempo of evolution across the Tree of Life. Herein, we demonstrate the importance of integrating fossil and extant species for inferring patterns of lineage diversification that would otherwise be masked in analyses that examine only one source of evidence. We infer the phylogeny and macroevolutionary history of the Tetraodontiformes (triggerfishes, pufferfishes and allies), a group with one of the most extensive fossil records among fishes. Our analyses combine molecular and morphological data, based on an expanded matrix that adds newly coded fossil species and character states. Beyond confidently resolving the relationships and divergence times of tetraodontiforms, our diversification analyses detect a major mass-extinction event during the Palaeocene-Eocene Thermal Maximum (PETM), followed by a marked increase in speciation rates. This pattern is consistently obtained when fossil and extant species are integrated, whereas examination of the fossil occurrences alone failed to detect major diversification changes during the PETM. When taking into account non-homogeneous models, our analyses also detect a rapid lineage diversification increase in one of the groups (tetraodontoids) during the middle Miocene, which is considered a key period in the evolution of reef fishes associated with trophic changes and ecological opportunity. In summary, our analyses show distinct diversification dynamics estimated from phylogenies and the fossil record, suggesting that different episodes shaped the evolution of tetraodontiforms during the Cenozoic.

RESUMO

The current work examined whether self-presentational efforts are influenced differently when people hold a goal to establish, maintain or repair an interpersonal connection. Results supported the counterintuitive prediction that participants with a repair goal would convey a less favourably oriented persona (e.g. less friendly, less similar and less genuine) compared to those with an establish or maintain goal. The efforts of repair goal participants were also perceived as less effective. The analysis also showed that certain self-presentation dimensions (i.e. friendliness, genuineness and similarity) mediated the relationship between acceptance goals and perceived effectiveness. The findings extend and contribute to the self-presentation and belongingness literatures.

RESUMO

Evidence indicates that people are motivated to interpret environmental cues to belongingness, but doing so can be challenging. Prior evidence shows that the self's regulatory resources are consumed when interpreting complex facial displays; with this study, we examined how the depletion of such resources may impact the ability to interpret vocal tones. Results showed that depletion decreased accuracy in identifying complex (vs. simple) vocal cues, which extends prior work and offers a more comprehensive understanding of the relationship between self-regulatory resources and the ability to effectively interpret one's social environment.

RESUMO

Time-calibrated phylogenies based on molecular data provide a framework for comparative studies. Calibration methods to combine fossil information with molecular phylogenies are, however, under active development, often generating disagreement about the best way to incorporate paleontological data into these analyses. This study provides an empirical comparison of the most widely used approach based on node-dating priors for relaxed clocks implemented in the programs BEAST and MrBayes, with two recently proposed improvements: one using a new fossilized birth-death process model for node dating (implemented in the program DPPDiv), and the other using a total-evidence or tip-dating method (implemented in MrBayes and BEAST). These methods are applied herein to tetraodontiform fishes, a diverse group of living and extinct taxa that features one of the most extensive fossil records among teleosts. Previous estimates of time-calibrated phylogenies of tetraodontiforms using node-dating methods reported disparate estimates for their age of origin, ranging from the late Jurassic to the early Paleocene (ca. 150-59Ma). We analyzed a comprehensive dataset with 16 loci and 210 morphological characters, including 131 taxa (95 extant and 36 fossil species) representing all families of fossil and extant tetraodontiforms, under different molecular clock calibration approaches. Results from node-dating methods produced consistently younger ages than the tip-dating approaches. The older ages inferred by tip dating imply an unlikely early-late Jurassic (ca. 185-119Ma) origin for this order and the existence of extended ghost lineages in their fossil record. Node-based methods, by contrast, produce time estimates that are more consistent with the stratigraphic record, suggesting a late Cretaceous (ca. 86-96Ma) origin. We show that the precision of clade age estimates using tip dating increases with the number of fossils analyzed and with the proximity of fossil taxa to the node under assessment. This study suggests that current implementations of tip dating may overestimate ages of divergence in calibrated phylogenies. It also provides a comprehensive phylogenetic framework for tetraodontiform systematics and future comparative studies.

RESUMO

BACKGROUND: Solid organ transplant patients often experience a variety of psychosocial stressors that can lead to distress and may hinder successful recovery. Using coping-infused dialogue (CID) through patient- preferred live music (PPLM) music therapy sessions may improve mood and decrease pain while also imparting psychoeducational knowledge concerning the identification of local and global problems and coping skills. OBJECTIVE: The purpose of this pilot study was to develop a coping-based medical music therapy protocol that combines coping-infused dialogue (CID) with patient-preferred live music (PPLM) and measure the effects of the resulting CID-PPLM protocol on mood (positive and negative affect) and pain in hospitalized transplant patients. METHODS: Our study used a pre-/posttest single-session wait-list control design. Participants (N=25) were randomly assigned to experimental (CID-PPLM) or control (usual care) conditions. Participants in the CID-PPLM condition received a single 30-minute session that integrated stressor identification and knowledge of coping skills (CID) with patient-preferred live music (PPLM). RESULTS: Results indicated no between-group differences at pretest and significant correlations between pre- and posttest measures. Concerning posttest ANCOVA analyses, there were significant between-group differences in positive affect, negative affect, and pain, with experimental participants having more favorable posttest scores than control participants. Effect sizes were in the medium-to-large range for positive affect (η2=.198), negative affect (η2=.422), and pain (η2=.303). CONCLUSIONS: CID through receptive PPLM may be an effective protocol for improving mood and decreasing pain in organ transplant recipients. MT interventions can be an important tool to develop rapport and enhance outcomes with patients. As greater engagement during interventions may have stronger treatment effects, we recommend future research examining patient engagement as a potential mediator of intervention effects, as well as the number of sessions required to maximize clinical outcomes.

RESUMO

We examined whether relational perceptions (social involvement, relational value, interaction experience) differ depending on interaction acceptance goals (establish, maintain, or repair). Results indicated that relational perceptions were more positive in the maintain condition compared to the establish condition, which in turn was more positive than the repair condition. The data also supported a moderated mediation model: the indirect effects of social involvement and relational value on the relationship between acceptance goals and participant's interaction experience were contingent on self-esteem. These findings identify boundary conditions that influence the impact of acceptance goals on how much people experience an interaction positively. The findings provide an integrated framework outlining the potential relationship between acceptance goals, relational perceptions, interaction experience, and self-esteem.

RESUMO

Understanding perceptions of global environmental issues, such as climate change, can help inform resource management, policy development, and communication with constituents. Although a considerable amount of research documents citizens' perceptions of climate change, few have investigated how interactions with climate-impacted parks and protected areas influence these perceptions, and consequently elements of environmental management. Using a mixed methods Instrument Development Approach, the researchers examined the stability of park visitors' (N = 429) climate change perceptions during a daylong interaction with climate-sensitive and influenced resources at Kenai Fjords National Park in Alaska. Results indicate that global-level beliefs about climate change remained relatively stable during a park experience, but perceptions about climate change at the park-level (e.g., impacts) appeared more malleable. Findings also revealed the type of park experience (terrestrial vs. marine) can influence the degree of change in visitors' perceptions. Implications for communication, outreach, and park management are discussed.

RESUMO

There is now a need more than ever to streamline services. A one-stop shoulder clinic was introduced during the COVID-19 pandemic. A total of 861 patients were seen, saving 794 future appointments. 111 patients had an ultrasound scan and 285 patients had an ultrasound-guided procedure, saving an average waiting time of 134 days. 327 patients had physiotherapy, and the average Oxford Shoulder Score improved by 8.56 at 1 year.

RESUMO

BACKGROUND: Smoking is a known neurotoxin that has been shown to negatively impact neurological function and recovery in multiple animal studies. Patients who smoke have been shown to have decreased rates of motor improvement, fusion, and overall successful outcomes after elective spinal surgery, but the effect of smoking on outcomes after traumatic spinal cord injury (TSCI) has not been demonstrated in prior literature. This study aims to investigate how smoking effects motor recovery after TSCI. METHODS: Using the National Spinal Cord Injury Statistical Center database, patients who underwent surgical management of American Spinal Injury Association grade D cervical TSCI between 2009 and 2016 were included. Patients were grouped by smoking or nonsmoking status. Overall total motor score and change in motor scores at rehabilitation admission, rehabilitation discharge, and 1-year follow-up visits were compared between groups. Multiple linear regression analysis was completed, including any possible confounding demographic or injury variables. RESULTS: A total of 152 patients (121 smokers and 31 nonsmokers) completed their 1-year follow-up interview and physical examination and were included in the study. There were no differences in motor score between groups at rehabilitation admission or discharge. Smokers had worse improvement in motor score at 1 year (7.99 nonsmokers vs 4.61 smokers; P = 0.019 on multivariate analysis) and worse overall total motor score at 1 year (94.0 nonsmokers vs 90.0 smokers; P = 0.018 on multivariate analysis) after controlling for confounders. CONCLUSIONS: These results indicate diminished motor recovery in patients who continue to smoke after TSCI. These patients should be targeted for aggressive smoking cessation and require intervention from providers and peers in order to maximize recovery after injury. CLINICAL RELEVANCE: This study demonstrates that smoking cessation may be beneficial for patients with cervical ASIA grade D spinal cord injury and may be a focus for providers of these patients.

RESUMO

BACKGROUND: The opioid crisis continues to worsen across the United States, affecting people of all demographics. Few evidence-based interventions exist for educating families, particularly those with adolescents, about opioid prescription safety. Serious games have demonstrated impacts in improving medication-related outcomes for various health conditions. The characterizing goal of this serious game is to improve opioid safety knowledge and awareness among adolescents and their families. OBJECTIVE: This study evaluated the impact of a serious game, MedSMARxT: Adventures in PharmaCity, designed to foster opioid safety awareness among adolescents and their parents. METHODS: A national sample of parents and their adolescent children was recruited through Qualtrics research panels, social media, listservs, and snowball sampling. Eligible participants were adolescents aged between 12 and 18 years and their parents. Study participants were required to reside in the United States; speak, read, and understand English; and have access to a computer with a webcam. Parent-child dyads completed pregame and postgame surveys and participated in gameplay for up to 30 minutes. Primary outcome scales have been previously evaluated by the study team. RESULTS: A total of 60 adolescent participants and 68 parent participants met full attention criteria for inclusion in this study. Statistical analysis confirmed that both adolescents' and parents' concept scores improved from baseline regarding opioid safety self-efficacy (adolescent: mean 0.35, SD 0.60; P<.001; parent: mean 0.28, SD 0.42; P<.001), perceived knowledge (adolescent: mean 1.08, SD 1.04; P<.001; parent: mean 0.56, SD 0.55; P<.001), behavioral intent (adolescent: mean 0.26, SD 0.39; P<.001; parent: mean 0.25, SD 0.32; P<.001), safe storage (adolescent: mean 0.12, SD 0.27; P<.001; parent: mean 0.03, SD 0.11; P=.03), disposal knowledge (adolescent: mean 0.10, SD 0.27; P=.006; parent: mean 0.07, SD 0.16; P<.001), and knowledge about misuse behavior (adolescent: mean 0.05, SD 0.14; P=.002; parent: mean 0.04, SD 0.10; P<.001). Participant groups, stratified by who completed and who did not complete gameplay, improved their knowledge and awareness, with no significant differences between subgroups. CONCLUSIONS: The use of this serious game to improve opioid prescription safety practices among parents and adolescents was supported by the study findings. MedSMARxT: Adventures in PharmaCity is an intervention with the capability of teaching parents and adolescents about safe opioid prescription practices. Further studies and game refinement are needed to demonstrate the effectiveness of a game-based intervention in clinical settings and community pharmacies.
