RESUMO
Given the importance of climate in shaping species' geographic distributions, climate change poses an existential threat to biodiversity. Climate envelope modeling, the predominant approach used to quantify this threat, presumes that individuals in populations respond to climate variability and change according to species-level responses inferred from spatial occurrence data-such that individuals at the cool edge of a species' distribution should benefit from warming (the "leading edge"), whereas individuals at the warm edge should suffer (the "trailing edge"). Using 1,558 tree-ring time series of an aridland pine (Pinus edulis) collected at 977 locations across the species' distribution, we found that trees everywhere grow less in warmer-than-average and drier-than-average years. Ubiquitous negative temperature sensitivity indicates that individuals across the entire distribution should suffer with warming-the entire distribution is a trailing edge. Species-level responses to spatial climate variation are opposite in sign to individual-scale responses to time-varying climate for approximately half the species' distribution with respect to temperature and the majority of the species' distribution with respect to precipitation. These findings, added to evidence from the literature for scale-dependent climate responses in hundreds of species, suggest that correlative, equilibrium-based range forecasts may fail to accurately represent how individuals in populations will be impacted by changing climate. A scale-dependent view of the impact of climate change on biodiversity highlights the transient risk of extinction hidden inside climate envelope forecasts and the importance of evolution in rescuing species from extinction whenever local climate variability and change exceeds individual-scale climate tolerances.

Bone toxicities are common among paediatric patients treated for acute lymphoblastic leukaemia (ALL) with potentially major negative impact on patients' quality of life. To identify the underlying genetic contributors, we conducted a genome-wide association study (GWAS) and a transcriptome-wide association study (TWAS) in 260 patients of European-descent from the DFCI 05-001 ALL trial, with validation in 101 patients of European-descent from the DFCI 11-001 ALL trial. We identified a significant association between rs844882 on chromosome 20 and bone toxicities in the DFCI 05-001 trial (p = 1.7 × 10-8). In DFCI 11-001 trial, we observed a consistent trend of this variant with fracture. The variant was an eQTL for two nearby genes, CD93 and THBD. In TWAS, genetically predicted ACAD9 expression was associated with an increased risk of bone toxicities, which was confirmed by meta-analysis of the two cohorts (meta-p = 2.4 × 10-6). In addition, a polygenic risk score of heel quantitative ultrasound speed of sound was associated with fracture risk in both cohorts (meta-p = 2.3 × 10-3). Our findings highlight the genetic influence on treatment-related bone toxicities in this patient population. The genes we identified in our study provide new biological insights into the development of bone adverse events related to ALL treatment.
RESUMO
BACKGROUND AND PURPOSE: Since the COVID-19 pandemic, the use and implementation of telehealth has expanded, with implementation moving ahead of best practice recommendations due to necessity. Telehealth has improved access and care coordination for patients with various neurologic conditions; however, information regarding therapeutic intensity, safety, and appropriateness is lacking. In 2021, the Academy of Neurologic Physical Therapy formed a Telehealth Taskforce to provide clinical and educational resources for its members and the neurologic physical therapy (PT) community. The purpose of this special interest article is to provide consensus-driven best practice resources developed by the Taskforce and describe the process of creating these resources to assist with telehealth implementation in neurologic PT practice, advocate for continued utilization, and shine light on opportunities for future research. SUMMARY OF KEY POINTS: In this special interest article, we describe the process, challenges, and opportunities of developing and disseminating resources to educate, train, and support telehealth implementation in neurologic clinical practice. Four key strategies to facilitate telehealth implementation emerged: (1) increase knowledge of resources related to telehealth and mobile applications; (2) develop and disseminate evidence-based and consensus-based best practice recommendations for telehealth in neurologic PT; (3) provide future recommendations for integrating telehealth in PT, education, research, and clinical practice; and (4) encourage advocacy for inclusion of telehealth within the PT community. We explain the need to continue research and provide recommendations to expand telehealth research in neurologic clinical practice. RECOMMENDATIONS FOR CLINICAL PRACTICE: This article highlights the potential and future of telehealth in neurologic PT practice. Our recommendations provide current clinical tools and resources for telehealth implementation following a knowledge-to-action framework and suggest areas for future research.Video Abstract available for more insights from the authors (see the Video, the Supplemental Digital Content, available at: http://links.lww.com/JNPT/A447).

PURPOSE: A 2016 American Academy of Orthopaedic Surgeons (AAOS) clinical practice guideline (CPG) de-emphasized the need for electrodiagnostic studies (EDS) for carpal tunnel syndrome (CTS). We tested the hypothesis that use of EDS decreased after the AAOS CPG. METHODS: Using a national administrative claims database, we measured the proportion of patients with a diagnosis of CTS who underwent EDS within 1 year after diagnosis between 2011 and 2019. Using an interrupted time series design, we defined 2 time periods (pre-CPG and post-CPG) and compared EDS usage between the periods using segmented regression analysis. We conducted a subgroup analysis of preoperative EDS usage in patients who underwent carpal tunnel release. RESULTS: Of 2,081,829 patients with CTS, 315,449 (15.2%) underwent EDS within 1 year after diagnosis. The segmented regression analysis showed a decrease in the level of EDS usage after publication of the AAOS CPG (-11.50 per 1,000 patients [95% CI, -1.47 to -0.95 per 1,000 patients]); however, the rate of EDS usage increased in the post-CPG period (+1.75 per 1,000 patients per quarter [95% CI, 0.97-2.54 per 1,000 patients per quarter]). Of 473,753 eligible patients who underwent carpal tunnel release, 139,186 (29.4%) underwent EDS within 6 months before surgery. After publication of the AAOS CPG, preoperative EDS usage decreased by -23.57 per 1,000 patients (95% CI, -37.72 to -9.42 per 1,000 patients). However, these decreasing trends in EDS usage predated the 2016 AAOS CPG. CONCLUSIONS: The overall and preoperative EDS usage for CTS has been decreasing since at least 2014, predating the 2016 AAOS CPG, reflecting the rapid implementation of evidence into practice. However, EDS usage has increased in the post-CPG period, and a considerable proportion of patients who underwent carpal tunnel release still received EDS. CLINICAL RELEVANCE: Given its high costs and disputed value, routine EDS usage should be considered for further deimplementation initiatives.

Estimates of the percentage of species "committed to extinction" by climate change range from 15% to 37%. The question is whether factors other than climate need to be included in models predicting species' range change. We created demographic range models that include climate vs. climate-plus-competition, evaluating their influence on the geographic distribution of Pinus edulis, a pine endemic to the semiarid southwestern U.S. Analyses of data on 23,426 trees in 1941 forest inventory plots support the inclusion of competition in range models. However, climate and competition together only partially explain this species' distribution. Instead, the evidence suggests that climate affects other range-limiting processes, including landscape-scale, spatial processes such as disturbances and antagonistic biotic interactions. Complex effects of climate on species distributions-through indirect effects, interactions, and feedbacks-are likely to cause sudden changes in abundance and distribution that are not predictable from a climate-only perspective.

BACKGROUND: A study was initiated at Roswell Park Comprehensive Cancer Center to capture the real-world experience related to the use of CDK4/6 inhibitors (Ciclibs) for the treatment of metastatic hormone receptor-positive and HER2-negative breast cancer (HR+/HER2-). PATIENTS AND METHODS: A total of 222 patients were evaluated who received CDK4/6 inhibitors in the period from 2015 to 2021. Detailed clinical and demographic information was obtained on each patient and used to define clinical and demographic features associated with progression-free survival on CDK4/6 inhibitor-based therapies. RESULTS: In this real-world analysis, the majority of patients received palbociclib as the CDK4/6 inhibitor with letrozole or fulvestrant as the predominant endocrine therapies. The median progression-free survival (PFS) in the letrozole (27.6 months) and fulvestrant (17.2 months) groups were comparable to that observed in clinical trials. As expected, age at start of the treatment and menopausal status influenced endocrine therapy utilization but were not associated with PFS. Patients with recurrent disease had shorter PFS (P = .0024) than those presenting with de novo metastasis. The presence of visceral metastasis trended toward shorter PFS (P = .051). Similarly, prior endocrine therapy (P = .003) or chemotherapy (P = .036) was associated with shorter PFS. Body mass index was not associated with PFS or with dose interruption and/or modification. While the number of minorities in this analysis is limited (n = 26), these patients as a group had statistically shorter PFS on treatment (P = .002). CONCLUSIONS: The real-world progression-free survival with CDK4/6 inhibitors mimics that observed in the clinical trial. A number of clinical and demographic features were associated with PFS on CDK4/6 inhibitor-based therapy. Further studies are ongoing to validate these findings incorporating additional cancer centers.

BACKGROUND: For patients with borderline annulus areas that fall between two valve sizes, overinflating a smaller balloon-expandable transcatheter heart valve (THV) may be preferable to nominal sizing of a larger THV. OBJECTIVES: To evaluate the outcomes of nominal preparation versus over-expanding an under-sized SAPIEN 3 Ultra (S3U) transcatheter heart valve (OE-THV) in cases with borderline annuli. METHODS: 958 patients that underwent TAVR with the S3U at four high-volume TAVR centers between January 2017 and December 2020 were retrospectively reviewed. 336 patients were identified as borderline annuli size, of which 146 (44%) received OE-THVs and 190 (56%) received nominal-sized THVs. The primary composite endpoint included: in-hospital mortality, aortic injury, moderate/severe paravalvular leak (PVL), permanent pacemaker implant (PPM), stroke, or conversion to surgery. RESULTS: Baseline characteristics were similar except for a larger percentage of females in the OE-THV (53.42% vs. 42.11%, p = 0.04). TAVR with OE-THV resulted a reduction in the primary composite endpoint (13.69% vs. 22.63%, p = 0.04). On subgroup analysis, there was no difference between 20 mm OE-THV versus 23 mm nominal or 23 mm OE-THV versus 26 mm nominal, but there was a reduction in the primary composite endpoint in patients with larger annuli that received a 26 mm OE-THV compared to the 29 mm nominally sized THV (9.7% vs. 27.4%, p = 0.02). At 1 month and 1 year follow-up, there was no significant difference in mortality, PVL rates, NYHA class, and/or KCCQ score. CONCLUSION: Overinflating a smaller-sized S3U THV may be a safer option in comparison to nominal sizing in patients with borderline annular area.

Vector-borne diseases (VBDs) are embedded within complex socio-ecological systems. While research has traditionally focused on the direct effects of VBDs on human morbidity and mortality, it is increasingly clear that their impacts are much more pervasive. VBDs are dynamically linked to feedbacks between environmental conditions, vector ecology, disease burden, and societal responses that drive transmission. As a result, VBDs have had profound influence on human history. Mechanisms include: (1) killing or debilitating large numbers of people, with demographic and population-level impacts; (2) differentially affecting populations based on prior history of disease exposure, immunity, and resistance; (3) being weaponised to promote or justify hierarchies of power, colonialism, racism, classism and sexism; (4) catalysing changes in ideas, institutions, infrastructure, technologies and social practices in efforts to control disease outbreaks; and (5) changing human relationships with the land and environment. We use historical and archaeological evidence interpreted through an ecological lens to illustrate how VBDs have shaped society and culture, focusing on case studies from four pertinent VBDs: plague, malaria, yellow fever and trypanosomiasis. By comparing across diseases, time periods and geographies, we highlight the enormous scope and variety of mechanisms by which VBDs have influenced human history.

There is a broad differential diagnosis for patients presenting with acute chest pain. History, physical examination, electrocardiogram, and serial troponin assays are pivotal in assessing patients with suspected acute coronary syndrome. However, if the initial workup is equivocal, physicians are faced with a challenge to find the optimal strategy for further triage. Risk stratification scores have been validated for patients with known acute coronary syndrome, such as the TIMI and GRACE scores, but there may be limitations in undifferentiated chest pain patients. Advancements in imaging modalities such as coronary computed tomography angiography and the addition CT derived fractional flow reserve, have demonstrated utility in evaluating patients presenting with acute chest pain. With this article, we aim to provide a comprehensive review of the non-invasive modalities that are available to evaluate acute chest pain patients suspected of cardiac etiology in the emergency room. We also added a focus on new imaging modalities that have shown to have prognostic implications in stable ischemic heart disease.

Understanding the role of consumers in density-dependent plant population dynamics is a long-standing goal in ecology. However, the generality of herbivory effects across heterogeneous landscapes is poorly understood due to the pervasive influence of context-dependence. We tested effects of native insect herbivory on the population dynamics of an exotic thistle, Cirsium vulgare, in a field experiment replicated across eight sites in eastern Nebraska. Using hierarchical Bayesian analysis and density-dependent population models, we found potential for explosive low-density population growth (λ > 5) and complex density fluctuations under herbivore exclusion. However, herbivore access drove population decline (λ < 1), suppressing complex fluctuations. While plant-herbivore interaction outcomes are famously context-dependent, we demonstrated that herbivores suppress potentially invasive populations throughout our study region, and this qualitative outcome is insensitive to environmental context. Our novel use of Bayesian demographic modelling shows that native insect herbivores consistently prevent hard-to-predict fluctuations of weeds in environments otherwise susceptible to invasion.

Background: Previous studies have shown that most professional head and orthopaedic team physicians are men, and most orthopaedic team physicians are fellowship-trained. It is unknown whether this holds true for primary care team physicians. Purpose: To evaluate the residency and fellowship training background as well as the demographic characteristics of primary care team physicians in professional sports. Study Design: Cross-sectional study. Methods: Publicly available information was used to determine the lead and supporting primary care team physicians for every US-based team in Major League Baseball, Major League Soccer, National Basketball Association, National Football League, National Hockey League, National Women's Soccer League, and Women's National Basketball Association. Data regarding training background and sex were obtained using internet-based sources. Results: We identified 310 primary care team physicians from all 165 US-based teams in the 7 leagues included in the study. Female physicians comprised 11.5% (19/165) of the lead primary care team physicians and 14.2% (44/310) of all primary care team physicians. Overall, 66.7% (110/165) of lead primary care team physicians and 75.5% (234/310) of all primary care team physicians were sports medicine fellowship-trained. There was a higher proportion of female (37.5%) and fellowship-trained (93.8%) physicians in women's professional sports leagues. Most primary care team physicians (244/310 [78.7%]) were trained in family medicine or internal medicine. Conclusion: Women constituted a small minority of primary care team physicians in professional sports. Most primary care team physicians were residency trained in family medicine or internal medicine and were sports medicine fellowship-trained. The proportion of female and fellowship-trained primary care team physicians was highest in the National Women's Soccer League and the Women's National Basketball Association.
RESUMO
The largest portion of breast cancer patients diagnosed after 70 years of age present with hormone receptor-positive (HR+) breast cancer subtypes. Cyclin-dependent kinase (CDK) 4/6 inhibitor treatment, in conjunction with endocrine therapy, has become standard-of-care for metastatic HR+ breast cancer. In total, 320 patients with metastatic breast cancer receiving CDK4/6 inhibitor combined with fulvestrant or an aromatase inhibitor were enrolled in an ongoing observational study or were included in an IRB-approved retrospective study. All patients receiving CDK4/6 inhibitor-based therapy that were ≥70 years of age (n = 111) displayed prolonged progression-free survival (27.6 months) as compared to patients <70 years of age (n = 209, 21.1 months, HR = 1.38, p < 0.05). Specifically, patients receiving a CDK4/6 inhibitor with an aromatase inhibitor who were ≥70 years of age (n = 79) displayed exceptionally prolonged progression-free survival (46.0 months) as compared to patients receiving the same treatment who were <70 years of age (n = 161, 21.8 months, HR = 1.71, p < 0.01). However, patients ≥70 years of age also experienced more frequent adverse responses to CDK4/6 inhibitor-based treatment leading to dose reduction, hold, or discontinuation than the younger cohort (69% and 53%, respectively). Treatment strategies that may decrease toxicity without affecting efficacy (such as dose titration) are worth further exploration.
RESUMO
BACKGROUND: Patient-reported outcome measures (PROMs) were originally developed as research tools; however, there is increasing interest in using PROMs to inform clinical care. Prior work has shown the benefits of implementing PROMs at the point of care, but a patient's health numeracy (their ability to understand and work with numbers) may affect their ability to interpret PROM results. MATERIALS AND METHODS: We recruited patients presenting to an outpatient orthopedic clinic. Forty-nine patients completed a survey that included demographic information, the short-form General Health Numeracy Test, and accuracy questions about four PROM displays (bar graph, table, line graph, pictograph) that indicated the same PROM results. RESULTS: Patients with higher health numeracy answered all display accuracy questions correctly (P=.016). Patients who preferred using the table were more likely to answer display accuracy questions incorrectly (odds ratio, 0.013, P=.024). The two most frequently preferred PROM formats were bar graphs and tables, and most patients preferred to learn about their PROM function scores via a combination of displays and verbal discussions. CONCLUSION: Patient health numeracy is associated with the ability to correctly interpret visual displays of PROMs. Implementation of PROMs at point of care currently does not account for health numeracy. Efforts to account for health numeracy when using PROMs at point of care may improve the efficacy of using PROMs to improve outcomes in orthopedic surgery. [Orthopedics. 202x;4x(x):xx-xx.].
RESUMO
Respiratory syncytial virus (RSV) is a common cause of respiratory infections, causing significant morbidity and mortality, especially in young children. Why RSV infection in children is more severe as compared to healthy adults is not fully understood. In the present study, we infect both pediatric and adult human nose organoid-air liquid interface (HNO-ALIs) cell lines with two contemporary RSV isolates and demonstrate how they differ in virus replication, induction of the epithelial cytokine response, cell injury, and remodeling. Pediatric HNO-ALIs were more susceptible to early RSV replication, elicited a greater overall cytokine response, demonstrated enhanced mucous production, and manifested greater cellular damage compared to their adult counterparts. Adult HNO-ALIs displayed enhanced mucus production and robust cytokine response that was well controlled by superior regulatory cytokine response and possibly resulted in lower cellular damage than in pediatric lines. Taken together, our data suggest substantial differences in how pediatric and adult upper respiratory tract epithelium responds to RSV infection. These differences in epithelial cellular response can lead to poor mucociliary clearance and predispose infants to a worse respiratory outcome of RSV infection.
RESUMO
BACKGROUND: The adaptation of retrograde tibial-pedal access for peripheral angiogram and intervention is limited by the lack of operator experience and concern for small distal vessel injury. This study evaluates the safety of the retrograde tibial-pedal access for peripheral angiogram and intervention in patients with two vessel infra-popliteal artery chronic total occlusions, where the access point is the sole remaining non-occluded infra-popliteal artery. METHODS: A retrospective analysis of 5687 consecutive patients who underwent peripheral angiograms by retrograde tibial-pedal access via the single remaining non-occluded infra-popliteal artery was performed. Patients who had retrograde tibial-pedal access at the sole remaining infra-popliteal artery confirmed by angiography were included. Clinical and ultrasound data of the accessed infra-popliteal vessel up to 6 months were collected. RESULTS: The cohort consisted of 314 patients (152 males; mean age 77.9 years). At 6 months, access vessel complications occurred in 15 patients (4.8%). Access vessel occlusion occurred in 9 out of 314 patients (2.9%), arteriovenous fistula in 4 (1.3%), with spontaneous resolution in 2, pseudoaneurysm requiring thrombin injection in 2 (0.6%) and non-cardiovascular death in 1 (0.3%). No uncontrolled bleeding, procedure-related hospitalizations or limb amputations occurred. CONCLUSIONS: Routine primary retrograde tibial-pedal access for lower extremity peripheral artery diagnostic angiography and intervention in patients with single infra-popliteal artery runoff can be safety performed in an outpatient setting with infrequent and manageable complications.
RESUMO
BACKGROUND: A novel volar approach to intra-articular distal radius fractures has been introduced for treatment of intra-articular distal radius fractures, in which volar extrinsic ligaments are released to create a volar window into the radiocarpal joint (Volar Intraarticular Extended Window [VIEW] approach). Our purpose was to evaluate the safety of VIEW approach for treatment of intra-articular distal radius fractures. METHODS: A retrospective chart review was performed for 13 patients with intra-articular distal radius fractures treated operatively with the VIEW surgical technique using an intra-articular window in the volar capsule to aid in reduction and fixation. Postoperative radiographs were reviewed to assess for ulnocarpal translocation by assessing lunate uncovering and radial-carpal distance. RESULTS: Thirteen patients were treated with the VIEW approach with mean follow-up of 28 weeks (range, 7-67 weeks; SD, 18 weeks). The mean postoperative lunate uncovering was 34.6% (SD, 7.7%) and mean radial-carpal distance was 4.6 mm (SD, 1.5 mm). Postoperatively, mean intra-articular step-off was 0.9 mm (SD, 1.2 mm) and mean intra-articular gap was 1.2 mm (SD, 1.0 mm). No patients reported clinical symptoms of wrist instability. CONCLUSIONS: Using the VIEW approach during a volar approach to intra-articular distal radius fractures is safe and does not lead to carpal instability. Surgeons can consider using the approach when direct visualization of the articular surface may be beneficial for reduction or fixation. LEVEL OF EVIDENCE: Therapeutic IV.
RESUMO
BACKGROUND CONTEXT: Although spine procedures have historically been performed inpatient, there has been a recent shift to the outpatient setting for selected cases due to increased patient satisfaction and reduced cost. Effective postoperative pain management while limiting over-prescribing of opioids, which may lead to persistent opioid use, is critical to performing spine surgery in the outpatient setting. PURPOSE: To assess if there is an increased risk for new, persistent opioid use between inpatient and outpatient spine procedures. STUDY DESIGN: Retrospective analysis using national administrative claims database. PATIENT SAMPLE: A total of 390,049 opioid-naïve patients with a perioperative opioid prescription who underwent an inpatient or outpatient spine surgery. OUTCOME MEASURES: Patients with perioperative opioid prescriptions who filled ≥ 1 opioid prescription between 90- and 180-days following surgery were defined as new, persistent opioid users. METHODS: We utilized a claims database to identify opioid-naïve patients who underwent lumbar or cervical fusion, total disc arthroplasty, or decompression procedures. We constructed a multivariable logistic regression to evaluate the association between inpatient versus outpatient surgery and the development of new, persistent opioid use while adjusting for several patient factors. RESULTS: A total of 19,205 (11.7%) inpatient and 18,546 (8.2%) outpatient patients developed new, persistent opioid use. Outpatient lumbar and cervical spine surgery patients were significantly less likely to develop new, persistent opioid use following surgery compared to inpatient spine surgery patients (OR = 0.71 [95% confidence interval {CI}: 0.69, 0.73], p < .001). Average morphine milligram equivalents (MMEs) (inpatient = 1,476 MME +/- 22.7, outpatient = 1,072 MME +/- 18.5, p < .001) and average MMEs per day (inpatient = 91.6 MME +/- 0.32, outpatient = 77.7 MME +/- 0.28, p < .001) were lower in the outpatient cohort compared to the inpatient. CONCLUSION: Our results support the shift from inpatient to outpatient spine procedures, as outpatient procedures were not associated with an increased risk for new, persistent opioid use. As more patients become candidates for outpatient spine surgery, predictors of new, persistent opioid use should be considered during risk stratification. LEVEL OF EVIDENCE: Level III Prognostic Study. MINI ABSTRACT: We utilized a national administrative claims database to identify opioid-naïve patients who underwent common spine procedures. Outpatient lumbar and cervical spine surgery patients were significantly less likely to be new, persistent opioid users following surgery compared to inpatient spine surgery patients. Our results support the shift to outpatient spine procedures.

Purpose: Exclusive breastfeeding promotes gut microbial compositions associated with lower rates of metabolic and autoimmune diseases. Its cessation is implicated in increased microbiome-metabolome discordance, suggesting a vulnerability to dietary changes. Formula supplementation is common within our low-income, ethnic-minority community. We studied exclusively breastfed (EBF) neonates' early microbiome-metabolome coupling in efforts to build foundational knowledge needed to target this inequality. Methods: Maternal surveys and stool samples from seven EBF neonates at first transitional stool (0-24 hours), discharge (30-48 hours), and at first appointment (days 3-5) were collected. Survey included demographics, feeding method, medications, medical history and tobacco and alcohol use. Stool samples were processed for 16S rRNA gene sequencing and lipid analysis by gas chromatography-mass spectrometry. Alpha and beta diversity analyses and Procrustes randomization for associations were carried out. Results: Firmicutes, Proteobacteria, Bacteroidetes and Actinobacteria were the most abundant taxa. Variation in microbiome composition was greater between individuals than within (p=0.001). Palmitic, oleic, stearic, and linoleic acids were the most abundant lipids. Variation in lipid composition was greater between individuals than within (p=0.040). Multivariate composition of the metabolome, but not microbiome, correlated with time (p=0.030). Total lipids, saturated lipids, and unsaturated lipids concentrations increased over time (p=0.012, p=0.008, p=0.023). Alpha diversity did not correlate with time (p=0.403). Microbiome composition was not associated with each samples' metabolome (p=0.450). Conclusion: Neonate gut microbiomes were unique to each neonate; respective metabolome profiles demonstrated generalizable temporal developments. The overall variability suggests potential interplay between influences including maternal breastmilk composition, amount consumed and living environment.
RESUMO
Despite widespread use and a known mechanism of action for CDK4/6 inhibitors in combination with endocrine therapy, features of disease evolution and determinants of therapeutic response in the real-world setting remain unclear. Here, a cohort of patients treated with standard-of-care combination regimens was utilized to explore features of disease and determinants of progression-free survival (PFS) and overall survival (OS). In this cohort of 280 patients, >90% of patients were treated with palbociclib in combination with either an aromatase inhibitor (AI) or fulvestrant (FUL). Most of these patients had modified Scarff-Bloom-Richardson (SBR) scores, and ER, HER2, and PR immunohistochemistry. Both the SBR score and lack of PR expression were associated with shorter PFS in patients treated with AI combinations and remained significant in multivariate analyses (HR = 3.86, p = 0.008). Gene expression analyses indicated substantial changes in cell cycle and estrogen receptor signaling during the course of treatment. Furthermore, gene expression-based subtyping indicated that predominant subtypes changed with treatment and progression. The luminal B, HER2, and basal subtypes exhibited shorter PFS in CDK4/6 inhibitor combinations when assessed in the pretreatment biopsies; however, they were not associated with OS. Using unbiased approaches, cell cycle-associated gene sets were strongly associated with shorter PFS in pretreatment biopsies irrespective of endocrine therapy. Estrogen receptor signaling gene sets were associated with longer PFS particularly in the AI-treated cohort. Together, these data suggest that there are distinct pathological and biological features of HR+/HER2- breast cancer associated with response to CDK4/6 inhibitors. Clinical trial registration number: NCT04526587.
RESUMO
Background: Severe tricuspid regurgitation (TR) may persist after a mitral transcatheter edge-to-edge repair (M-TEER) and is associated with worsened clinical outcomes and survival. It is unclear which patients with concomitant mitral regurgitation (MR) and TR will have TR reduction after M-TEER. The aim of this study was to identify the predictors of residual TR after transcatheter edge-to-edge repair (TEER). Methods: Data were collected from the Northwell TEER registry, a prospectively maintained mandatory database including 4 high-volume transcatheter aortic valve replacement/TEER centers. Transthoracic echocardiograms, both pre-TEER and post-TEER, were evaluated. Univariate and multivariate logistic regression analyses were performed to identify predictors of severe TR after M-TEER. Significant TR reduction was defined as a reduction in TR grade by at least 1+ with moderate (2+) or less TR at 1 month. Results: Of the 479 patients who underwent M-TEER, 107 patients with concomitant severe MR/TR were included. Successful MR reduction occurred in 89 patients (84%) and a significant TR reduction in 45 (42%). On the univariate analysis, the only predictors of severe residual TR were right atrial area and unsuccessful M-TEER. On the multivariate logistic regression model, the only predictor variable for patients with a reduction in TR was MR reduction of ≥3+ with M-TEER. Conclusions: In patients with concomitant severe MR and TR, TR reduction after isolated M-TEER occurs in only â¼40% of patients. MR grade reduction ≥3+ was the only independent predictor for TR reduction. Other clinical and echocardiographic variables (including pulmonary hypertension, right ventricular function, tricuspid annular dilation, atrial fibrillation, and presence of a cardiac implantable electrical device) were not associated with residual TR. Inability to predict TR reduction after M-TEER highlights the importance of establishing transcatheter tricuspid valve therapies and should factor in heart-team discussions.
