Evaluating surgeon communication of pancreatic cancer prognosis using the VitalTalk ADAPT framework.

BACKGROUND AND OBJECTIVES: Few data exist to guide optimal communication practices for surgical oncologists. VitalTalk, an evidence-based communication skills training model for clinicians, offers the five-step ADAPT tool for discussing prognosis. This study aimed to characterize surgeon communication of pancreatic cancer prognosis using VitalTalk's ADAPT framework. METHODS: Contemporaneous audio recordings from 12 initial surgeon-patient encounters for borderline resectable pancreatic cancer were transcribed. Directed qualitative content analysis based on ADAPT (Ask, Discover, Anticipate, Provide, and Track) was used to deductively code transcripts. RESULTS: All encounters contained at least one ADAPT step while only one (8%) incorporated four or five steps. Surgeons provided prognostic information (Provide) in all but one encounter (92%); most was qualitative and clustered into themes: serious illness, surgical candidacy, prognostic ambiguity, and cancer recurrence. Surgeons elicited understanding (Ask), requested information preferences (Discover), anticipated ambivalence (Anticipate), and responded to emotion (Track) in a minority of encounters (25%-42%); of 15 patient emotional cues, six were not addressed by surgeons. CONCLUSIONS: During an initial encounter for pancreatic cancer, surgeons focus heavily on providing information but omit critical prognostic communication steps. Future studies are needed to investigate if surgeon training in palliative care-based communication is feasible and impacts patient-perceived quality of communication.

Congenital Hypothyroidism Long-Term Follow-up Project: Navigating the Rough Waters of a Multi-Center, Multi-State Public Health Project.

The Region 4 Midwest Genetics Collaborative, made up of seven regional states (Illinois, Indiana, Kentucky, Michigan, Minnesota, Ohio, and Wisconsin), brought together pediatric endocrinologists, state laboratory experts, public health follow-up specialists, and parents of children with congenital hypothyroidism (CH) to identify the three-year follow-up management and education patterns of primary care clinicians and pediatric endocrinologists in the care of children diagnosed with CH by state newborn screening (NBS) programs. Among a number of challenges, each state had different NBS methods, data systems, public health laws, and institutional review board (IRB) requirements. Furthermore, the diagnosis of CH was complicated by the timing of the NBS sample, the gestational age, weight, and co-morbidities at delivery. There were 409 children with CH identified through NBS in 2007 in the seven state region. The clinician of record and the parents of these children were invited to participate in a voluntary survey. Approximately 64 % of clinician surveys were collected with responses to questions relating to treatment, monitoring practices, educational resources, genetic counseling, and services provided to children with confirmed CH and their families. Nearly one-quarter (24 %) of parents surveyed responded to questions relating to treatment, education, genetic counseling, resources, and services they received or would like to receive. De-identified data from six of the seven states were compiled for analysis, with one state being unable to obtain IRB approval within the study timeline. The data from this collaborative effort will improve state follow-up programs and aid in developing three-year follow-up guidelines for children diagnosed with CH. To aid in the facilitation of similar public health studies, this manuscript highlights the challenges faced, and focuses on the pathway to a successful multi-state public health endeavor.

Understanding Tendon Fibroblast Biology and Heterogeneity.

Tendon regeneration has emerged as an area of interest due to the challenging healing process of avascular tendon tissue. During tendon healing after injury, the formation of a fibrous scar can limit tendon strength and lead to subsequent complications. The specific biological mechanisms that cause fibrosis across different cellular subtypes within the tendon and across different tendons in the body continue to remain unknown. Herein, we review the current understanding of tendon healing, fibrosis mechanisms, and future directions for treatments. We summarize recent research on the role of fibroblasts throughout tendon healing and describe the functional and cellular heterogeneity of fibroblasts and tendons. The review notes gaps in tendon fibrosis research, with a focus on characterizing distinct fibroblast subpopulations in the tendon. We highlight new techniques in the field that can be used to enhance our understanding of complex tendon pathologies such as fibrosis. Finally, we explore bioengineering tools for tendon regeneration and discuss future areas for innovation. Exploring the heterogeneity of tendon fibroblasts on the cellular level can inform therapeutic strategies for addressing tendon fibrosis and ultimately reduce its clinical burden.

Opioid Use After Robotic-Assisted Versus Conventional Total Hip Arthroplasty:A National Database Analysis.

BACKGROUND: In this study, we tested the null hypothesis that robotic-assisted total hip arthroplasty (THA) vs conventional THA was not associated with (1) the amount of postoperative opioid use and (2) the incidence of new, persistent opioid use. MATERIALS AND METHODS: We used a large, national administrative database to identify patients 50 years and older undergoing primary robotic or conventional THA. Patients with hip fractures or a history of malignancy, hip infection, or opioid use disorder were excluded. Patients who filled an opioid prescription within 1 year to 30 days preoperatively or who underwent a subsequent procedure within 1 year after THA were excluded. Outcomes included the morphine milligram equivalents (MMEs) filled within the THA perioperative period and the incidence of new, persistent opioid use. Multivariable logistic regression models were used to evaluate associations between robotic-assisted THA and new, persistent opioid use, adjusting for age, sex, insurance plan, region, location of surgery, and comorbidities. RESULTS: In the postoperative period, robotic-assisted THA, compared with conventional THA, was associated with a lower mean total MMEs filled per patient (452.2 vs 517.1; P<.001) and a lower mean MMEs per patient per day (71.53 vs 74.64; P<.001). Patients undergoing robotic-assisted THA had decreased odds of developing new, persistent opioid use compared with patients undergoing conventional THA (adjusted odds ratio, 0.82 [95% CI, 0.74-0.90]). CONCLUSION: Robotic-assisted THA is associated with lower postoperative opioid use and a decreased odds of developing new, persistent opioid use compared with conventional THA. For the purposes of reducing opioid use, our results support the adoption of robotic-assisted THA. [Orthopedics. 202x;4x(x):xx-xx.].

T cells and macrophages jointly modulate osteogenesis of mesenchymal stromal cells.

Approximately 5%-10% of fractures go on to delayed healing and nonunion, posing significant clinical, economic, and social challenges. Current treatment methods involving open bone harvesting and grafting are associated with considerable pain and potential morbidity at the donor site. Hence, there is growing interest in minimally invasive approaches such as bone marrow aspirate concentrate (BMAC), which contains mesenchymal stromal cells (MSCs), macrophages (Mφ), and T cells. However, the use of cultured or activated cells for treatment is not yet FDA-approved in the United States, necessitating further exploration of optimal cell types and proportions for effective bone formation. As our understanding of osteoimmunology advances, it has become apparent that factors from anti-inflammatory Mφ (M2) promote bone formation by MSCs. Additionally, M2 Mφ promote T helper 2 (Th2) cells and Treg cells, both of which enhance bone formation. In this study, we investigated the interactions among MSCs, Mφ, and T cells in bone formation and explored the potential of subsets of BMAC. Coculture experiments were conducted using primary MSCs, Mφ, and CD4+ T cells at specific ratios. Our results indicate that nonactivated T cells had no direct influence on osteogenesis by MSCs, while coculturing MSCs with Mφ and T cells at a ratio of 1:5:10 positively impacted bone formation. Furthermore, higher numbers of T cells led to increased M2 polarization and a higher proportion of Th2 cells in the early stages of coculture. These findings suggest the potential for enhancing bone formation by adjusting immune and mesenchymal cell ratios in BMAC. By understanding the interactions and effects of immune cells on bone formation, we can develop more effective strategies and protocols for treating bone defects and nonunions. Further studies are needed to investigate these interactions in vivo and explore additional factors influencing MSC-based therapies.

Wide-ranging genetic variation in sensitivity to rapamycin in Drosophila melanogaster.

The progress made in aging research using laboratory organisms is undeniable. Yet, with few exceptions, these studies are conducted in a limited number of isogenic strains. The path from laboratory discoveries to treatment in human populations is complicated by the reality of genetic variation in nature. To model the effect of genetic variation on the action of the drug rapamycin, here we use the growth of Drosophila melanogaster larvae. We screened 140 lines from the Drosophila Genetic References Panel for the extent of developmental delay and found wide-ranging variation in their response, from lines whose development time is nearly doubled by rapamycin, to those that appear to be completely resistant. Sensitivity did not associate with any single genetic marker, nor with any gene. However, variation at the level of genetic pathways was associated with rapamycin sensitivity and might provide insight into sensitivity. In contrast to the genetic analysis, metabolomic analysis showed a strong response of the metabolome to rapamycin, but only among the sensitive larvae. In particular, we found that rapamycin altered levels of amino acids in sensitive larvae, and in a direction strikingly similar to the metabolome response to nutrient deprivation. This work demonstrates the need to evaluate interventions across genetic backgrounds and highlights the potential of omic approaches to reveal biomarkers of drug efficacy and to shed light on mechanisms underlying sensitivity to interventions aimed at increasing lifespan.
