Purpose
Americans with limited English proficiency (LEP) face significant barriers to health care that result in health disparities in the LEP population. LEP could delay an MRI, potentially increasing morbidity and mortality in the LEP population. This study compares the time to obtain a neurological MRI in English versus non-English language preference patients.Methods
24,219 unique patients at a single health system who underwent inpatient neurological MRI were included in the study. Bivariate and multivariate analyses were used to identify characteristics predictive of time to examination (TTE) from the set: patient-preferred language, gender, race, age, performing hospital, and order priority (routine versus stat).Results
Bivariate analysis showed a longer TTE is associated with increasing age category, non-English language preference, and routine priority. A multivariate analysis showed non-English language preference effect on TTE is reduced in magnitude and is no longer significant in a model that includes age group, priority, and hospital (P = .23, effect estimate = 4%, 95% CI: ?2.5%, 11.0%). Routine order priority (P < .0001) and increasing age (P < .0001) were associated with increased TTE. In a model that included interactions, the effect of language preference did not depend on order priority (P = .59) or age group (P = .11).Conclusion
There is no significant difference in the time to obtain a neurological MRI in English versus non-English language preference patients when age, order priority, and performing hospital are accounted for. This finding supports the effectiveness of the protocols and resources in place to support patients with LEP at the sponsoring health system. 相似文献2.

Purpose
To compare automated measurements of maximal diameter (Dmax) of abdominal aortic aneurysm (AAA) orthogonal to luminal or outer wall envelope centerline for endovascular repair (EVAR) follow-up.Material and Methods
Eighty-three consecutive patients with AAA treated by EVAR who had at least 1 computed tomography (CT) scan before and 2 CT scans after EVAR with at least 5 months’ interval were included. Three-dimensional reconstruction of the AAA was achieved with dedicated segmentation software. Performances of automated calculation algorithms of Dmax perpendicular to lumen or outer wall envelope centerlines were then compared to manual measurement of Dmax on double-oblique multiplanar reconstruction (gold standard). Accuracy of automated Dmax measurements at baseline, follow-up, and progression over time was evaluated by calculation of mean error, Bland-Altman plot, and regression models.Results
Disagreement in Dmax measurements between outer wall envelope algorithm and manual method was insignificant (mean error: baseline, -0.07 ± 1.66 mm, P = .7; first follow-up, 0.24 ± 1.69 mm, P = .2; last follow-up, -0.41 ± 2.74 mm, P = .17); whereas significant discrepancies were found between the luminal algorithm and the manual method (mean error: baseline, -1.24 ± 2.01 mm, P < .01; first follow-up, -1.49 ± 3.30 mm, P < .01; last follow-up, -1.78 ± 3.60 mm, P < .01). Dmax progression results were more accurate with AAA outer wall envelope algorithm compared to luminal method (P = .2).Conclusions
AAA outer wall envelope segmentation is recommended to enable automated calculation of Dmax perpendicular to its centerline during EVAR follow-up. 相似文献3.

Purpose
To evaluate the influence of percutaneous cryoablation for renal cell carcinoma on function of the affected kidney.Materials and Methods
Between June 2016 and September 2017 at our institution, 12 inoperable patients underwent 15 cryoablation sessions for 17 small renal tumors. Of these, 9 patients who underwent 11 sessions of cryoablation were the focus of this study. For those patients, time-dependent changes in postoperative renal function were investigated by a retrospective review of clinical records. Evaluated were the estimated glomerular filtration rate (eGFR) and scintigraphy using 99m technetium-mercaptoacetyltriglycine (99mTc-MAG3) before and 1 week, 1–2 months, and more than 6 months after cryoablation.Results
Mean baseline eGFR was 76.88 ± 29.82 mL/min/1.73 m2 (mean ± standard deviation; range, 23.4–112.5). Mean eGFR 1 week, 1–2 months, and more than 6 months after cryoablation were 74.56 ± 26.68 mL/min/1.73 m2 (21.0–101.1), 69.5 ± 25.28 mL/min/1.73 m2 (24.1–105.6), and 75.08 ± 26.25 mL/min/1.73 m2 (29.0–107.3), respectively. Changes were statistically insignificant (P = .6044, P = .6699, and P = .9038, respectively). Regarding split renal function, the mean baseline contribution of the affected kidney determined by 99mTc-MAG3 was 47.27% ± 6.14 (38.8%–57.0%). Mean contributions of the affected kidney 1 week after, 1–2 months after, and more than 6 months after cryoablation were 44.40% ± 5.37 (38.3%–53.6%), 44.57% ± 6.52 (34.35%–55.0%), and 45.41% ± 7.77 (34.4%–56.5%), respectively. Differences from baseline were significant for the earliest 2 periods (P = .0473 and P = .0334, respectively) but not the later period (P = .2532).Conclusions
Results suggested that total renal function does not worsen after cryoablation; however, function of the affected kidney worsened after cryoablation but later partially recovered. 相似文献4.

Purpose
To compare perioperative and long-term outcomes of endovascular aneurysm repair (EVAR) with flared limbs (FLs) vs iliac branch devices (IBDs) for common iliac artery aneurysm to determine possible differences in outcome.Materials and Methods
From 2012 to 2017, all patients with standard EVAR with FLs and aortoiliac anatomy fit for implantation of IBDs were retrospectively selected and compared with patients with standard EVAR and IBDs. The study included 150 patients with 162 iliac treatments: 105 (65%) FLs and 57 (35%) IBDs. Iliac complications (ICs), including internal iliac artery (IIA) loss, limb thrombosis, and type 1b or type 3 endoleak, were considered at 30 days and in the follow-up period.Results
Procedural time and volume of contrast medium were significantly higher in IBD vs FL procedures (90 min ± 33 vs 70 min ± 25, P = .01; 130 mL ± 40 vs 80 mL ± 20, P = .01). Perioperative rate of ICs was similar between IBDs and FLs (0% vs 3.8% [4 IIA loss], P = .25). During 35-month median follow-up, there were 10 ICs, all in FLs group (4 IIA perioperative loss, 4 type 1b endoleak, 2 limb occlusion). By Kaplan-Meier analysis, survival free of ICs was significantly higher in IBD group after 4 years of follow-up (1 y 100% vs 96%, P = .36; 2 y 100% vs 94%, P = .14; 3 y 100% vs 91%, P = .07; 4 y 100% vs 87%, P = .03; 5 y 100% vs 78%, P = .02).Conclusions
IBDs and FLs have similar perioperative results. IBDs require longer procedural time and greater contrast medium volume; however, they are associated with lower ICs after 4 years of follow-up. 相似文献5.

Purpose
To determine if there is a correlation between intrahepatic tumor volume and future liver remnant (FLR) hypertrophy after portal vein embolization (PVE).Materials and Methods
Forty-four consecutive patients with hepatocellular carcinoma or metastatic colorectal cancer who underwent PVE from 2009 to 2017 and who had complete imaging follow-up were retrospectively reviewed. To maximize the accuracy of tumor volume measurements, 11 patients were excluded for having more than 5 intrahepatic tumors. Volumetric analyses of the patient livers before and after PVE, as well as pre-embolization intrahepatic tumor burden, were performed.Results
A significant inverse correlation was observed between tumor volume and FLR hypertrophy after PVE (Spearman ρ = -0.53, P = .002). Initial FLR volume was also inversely correlated with subsequent hypertrophy (P = .01). Fourteen patients received neoadjuvant chemotherapy 1 month prior to intervention. The number of chemotherapy cycles did not affect hypertrophy (P = .57). Patients with cirrhosis experienced less FLR hypertrophy than patients without cirrhosis (P = .02).Conclusions
Patients with large intrahepatic tumor burden may experience limited FLR hypertrophy. 相似文献6.

Purpose
To compare treatment with hepatic arterial infusion of chemotherapy (HAIC) in patients with advanced hepatocellular carcinoma (HCC) with both extrahepatic spread (EHS) and intrahepatic tumor and patients with intrahepatic tumor only.Materials and Methods
This single-center retrospective study comprised 116 patients with advanced HCC with both intrahepatic tumor and EHS (EHS group; n = 50) or with intrahepatic tumor only (non-EHS group; n = 66) treated with HAIC including oxaliplatin, fluorouracil, and leucovorin between June 2014 and July 2016. Overall survival (OS) and radiologic responses to treatment were determined and compared between the 2 groups.Results
Both the objective response rate and the clinical benefit rate were higher in the non-EHS group than in the EHS group (37.9% vs 16% objective response rate, P = .010; 81.8% vs 62% clinical benefit rate, P = .017). Median OS was not statistically different between the 2 groups (14.8 months vs 9.8 months, P = .068). Subgroup analysis of OS found that patients with lung metastases survived for a shorter time (OS 7 months) than patients with other metastatic sites (P = .003) and patients free of metastases (P = .001).Conclusions
HAIC is a potential treatment option for advanced HCC with limited extrahepatic metastases in a population with hepatitis B virus infection. 相似文献7.

Purpose
To retrospectively compare long-term outcomes of conventional chemoembolization plus radiofrequency (RF) ablation vs those of surgical resection in patients with a single 3–5-cm hepatocellular carcinoma (HCC).Materials and Methods
From January 2008 to December 2017, 139 of 623 patients who underwent surgical resection and 60 of 186 patients who underwent chemoembolization/RF ablation in a single center were compared with respect to local tumor progression (LTP), intrahepatic distant recurrence (IDR), disease-free survival (DFS), overall survival (OS), major complications, and hospital stay before and after propensity-score matching.Results
Mean follow-up periods were similar in the chemoembolization/RF ablation and surgical resection groups (41.9 mo vs 48.4 mo). Three (5%) and 17 (28.3%) patients in the chemoembolization/RF ablation group and 12 (8.6%) and 57 (41.0%) patients in the surgical resection group showed LTP and IDR (P = .366 and P =.114, respectively). At 1, 3, and 5 years, respective DFS rates were 88.1%, 65.3%, and 49.0% for chemoembolization/RF ablation and 84.2%, 58.2%, and 46.5% for surgical resection (P = .294). Moreover, respective OS rates were 95.0%, 73.5%, and 54.0% for chemoembolization/RF ablation and 97.1%, 87.4%, and 75.0% for surgical resection (P = .055). After matching (n = 52), therapeutic outcomes remained similar (P = .370, P = .110, P = .230, and P = .760, respectively). Surgical resection was associated with higher complication rates (P = .015) and longer hospital stays (8.4 d ± 3.7 vs 16.9 d ± 7.0; P < .001).Conclusions
Conventional chemoembolization combined with RF ablation may be feasible for single 3–5-cm HCCs, with comparable therapeutic outcomes vs surgical resection and shorter hospital stays. 相似文献8.

Purpose
To determine patient preference for transradial access (TRA) or transfemoral access (TFA) after experiencing both.Materials and Methods
A randomized controlled crossover trial was conducted at a single institution. Thirty patients with hepatocellular carcinoma undergoing mapping and transarterial radioembolization (TARE) were enrolled to experience 1 TRA and 1 TFA procedure each, with randomization of which access approach was experienced first. Surveys assessing pain and quality of life (QOL) were administered after each procedure. Access site preference was collected after completion of both procedures.Results
Twenty-two subjects (73.3%) preferred TRA, 4 (13.3%) preferred TFA, and 4 (13.3%) had no preference; 14 (46.7%) reported bruising after TRA, and 17 (53.3%) reported bruising after TFA. TRA was associated with significantly lower pain scores overall during the procedure, at the access site during the procedure, and in the recovery room compared with TFA (2.0 vs 2.9, P = .0046; 2.0 vs 3.0, P = .0004; 2.1 vs 2.9, P = .0357). Pain score after discharge was not significantly different (1.4 vs 1.5, P = .4235). QOL scores were not significantly different between TRA and TFA. No significant differences were found for fluoroscopy time, air kerma, dose-area product, or procedure time between TRA and TFA for either mapping (P = .1442, P = .5871, P = .6667, P = .6131) or radioembolization (P = .8574, P = .2344, P = .1119, P =.8474). For radioembolizations, TRA had significantly shorter recovery times compared with TFA (108 min vs 153 min, P = .0193).Conclusions
Patients exhibited a strong preference for TRA. With TRA, patients experienced less periprocedural pain and shorter recovery times without significant differences in radiation exposure or procedure length. 相似文献9.

Objectives
Studies have shown that having a baseline mammogram, the first screening mammogram, available for comparison at the time of interpreting a subsequent mammogram significantly decreases the potential of a false-positive examination. Our aim was to evaluate knowledge of and perception about the significance of baseline mammograms in those women undergoing screening mammography.Materials and Methods
A cross-sectional prospective survey study was conducted in women without a history of breast cancer presenting for their screening mammogram. Respondents were surveyed anonymously between March and April 2017. The questionnaire was developed by primary care providers and radiologists and pretested for readability and clarity.Results
In all, 401 women (87% white, 93% educated beyond high school) completed surveys in which 77% of women reported having yearly mammograms, 31% reported having a history of an abnormal mammogram, and 45% had not heard the term baseline mammogram. Of those who had heard the term, the most commonly reported source was their primary care provider (31%). Although 74% chose the correct definition of a baseline mammogram, 67% did not think that a baseline mammogram was important for decreasing associated cost, time, and discomfort due to the number of mammograms incorrectly read as abnormal.Conclusion
In a group of educated women who routinely get mammograms, almost one-half had not heard the term baseline mammogram. Furthermore, most women did not think baseline mammography was important for decreasing associated cost, time, and discomfort due to mammograms incorrectly read as abnormal. This study suggests that efforts to improve women’s understanding of baseline mammograms and their importance are warranted, with greatest opportunity for health care providers and radiologists. 相似文献10.

Purpose
To evaluate the effects of the degree of ethiodized oil accumulation achieved by transarterial chemoembolization followed by radiofrequency (RF) ablation on the treatment efficacy for a single intermediate-sized hepatocellular carcinoma (HCC).Materials and Methods
A total of 153 consecutive patients who underwent chemoembolization and RF ablation for a single intermediate-sized HCC (2–5 cm) were included. On the basis of the degree of ethiodized oil accumulation in HCC on cone-beam CT images, patients who underwent chemoembolization and RF ablation were classified into 2 groups: compact accumulation (≥ 75%) and noncompact accumulation (< 75%). The rates of cumulative local tumor progression (LTP), disease-free survival (DFS), and overall survival (OS) were compared between groups.Results
Of the 153 patients, 89 were classified into the compact ethiodized oil accumulation group and 64 in the noncompact ethiodized oil accumulation group. There were no significant differences in patient demographic or HCC characteristics between groups except for the incidence of liver cirrhosis (P = .038) and the tumor margin morphology (P = .008). The cumulative LTP rate was significantly lower in the compact accumulation group than in the noncompact accumulation group (P = .013). There were no significant differences in the incidences of complications, DFS rates (P = .055), or OS rates (P = .184).Conclusions
The degree of ethiodized oil accumulation does not play a role in decreasing the OS or DFS rate after chemoembolization and RF ablation for intermediate-sized HCC; however, it may contribute to reducing the rate of LTP. 相似文献11.

Purpose
To investigate the current state of gender diversity among invited coordinators at the Society of Interventional Radiology (SIR) Annual Scientific Meeting and to compare the academic productivity of female interventional radiologists to that of invited male coordinators.Materials and Methods
Faculty rosters for the SIR Annual Scientific Meetings from 2015 to 2017 were stratified by gender to quantify female representation among those asked to lead and coordinate podium sessions. To quantify academic productivity and merit, H-index, publications, and authorship by females over a 6-year period (2012–2017) were statistically compared to that of recurring male faculty.Results
From 2015 to 2017, women held 7.1% (9/126), 4.3%, (8/188), and 13.7% (27/197) of the available coordinator positions for podium sessions, with no representation at the plenary sessions, and subject matter expertise was concentrated in economics and education. Academic productivity of the top quartile of published female interventional radiologists was statistically similar to that of the invited male faculty (H-index P = .722; total publications P = .689; and authorship P = .662).Conclusions
This study found that senior men dominate the SIR Annual Scientific Meeting, with few women leading or coordinating the podium sessions, despite their established academic track record. 相似文献12.

Objectives
To provide epidemiological data and related costs for moderate-to-serious and serious injury claims for women’s rugby union in New Zealand.Design
A retrospective analytical review of injury entitlement claims for women’s rugby from 2013 to 2017.Methods
Data were analysed by year of competition, age, body site and injury type for total and moderate-to-severe (MSC) Accident Compensation Corporation (ACC) claims and costs.Results
Over 2013 to 2017 there were 26,070 total claims for female rugby union costing $18,440,812 [AD$16,956,998]. The 15–19-year age group recorded 40% (n = 1,009) of the total female rugby union Moderate-to-serious and serious (MSC) claims and 41% ($5,419,157 [AD$4,983,112]) of the total female rugby union MSC costs. The knee was the most commonly recorded injury site accounting for 40.3% (n = 1,007) of MSC claims and 46.9% ($6,229,714 [AD$5,728732]) of MSC costs with an average cost of $1,245,943 ±$217,796 [AD$595,351 ±AD$104,070] per-year for female rugby union.Conclusions
This is the first study to report the nature and related costs for moderate-to-serious and serious injury claims for women’s rugby union in New Zealand. A total of 26,070 injury claims were lodged over the duration of the study but only 9.6% (n = 2,501) of these were classified as MSC injury entitlement claims. Participants 25 years and older accounted for 31% of the female rugby union player claims. Females in the over 35-year age groups compete against younger participants which may account for the higher mean cost per-claim seen as the age groups increase in years until they retire from the game. 相似文献13.

Objective
We conducted a national survey to understand the impact of state-level density reporting laws on women’s level of density risk awareness and their engagement in conversations with providers regarding supplemental screening.Methods
In all, 1,500 US women aged 40 to 74 years who obtained a mammogram within 2 years were surveyed in February 2018. The sampling design yielded 300 respondents in each of five groups categorized based on density reporting law features. Women were asked about their breast density-related knowledge, importance of being notified, and sources of information and if conversations with providers regarding density and supplemental screening occurred. Survey results were compared across groups and between women residing in states with versus without density laws.Results
The majority of respondents in all groups felt that it is important for women to know their breast density type (range, 85%-90%). Women were most likely informed of breast density type by a health care provider (range, 68%-72%), followed by the mammography result letter (range, 48%-68%), and then a radiologist (range, 46%-61%). Women from states with a density law were significantly more likely to have learned of their breast tissue type from a mammogram results letter (60% versus 48%, P = .011) and discuss supplemental screening (67% versus 53%, respectively; P = .008) than women from states without a law.Conclusion
State-level density reporting laws are associated with increased breast density awareness and increased likelihood of conversations between women and their providers regarding supplemental screening. 相似文献14.

Objectives
The current study investigated the effects of two exercise interventions on cognitive function amongst breast cancer survivors.Design
Pilot randomised-controlled trial.Methods
Seventeen female cancer survivors (mean: 62.9 ± 7.8 years) were randomised into three groups: high-intensity interval training (HIIT, n = 6); moderate-intensity continuous training (MOD, n = 5); or wait-list control (CON, n = 6). The HIIT and MOD groups exercised on a cycle ergometer 3 days/week for 12-weeks. Primary outcomes were cognitive function assessments utilising CogState. Secondary outcomes were resting middle cerebral artery blood flow velocity, cerebrovascular reactivity and aerobic fitness (VO2peak). Data were analysed with General Linear Mixed Models and Cohen’s d effect sizes were calculated.Results
All 17 participants who were randomised were available for follow-up analysis and adherence was similar for HIIT and MOD (78.7 ± 13.2% vs 79.4 ± 12.0%; p = 0.93). Although there were no significant differences in the cognitive and cerebrovascular outcomes, HIIT produced moderate to large positive effects in comparison to MOD and CON for outcomes including episodic memory, working memory, executive function, cerebral blood flow and cerebrovascular reactivity. HIIT significantly increased VO2peak by 19.3% (d = 1.28) and MOD had a non-significant 5.6% (d = 0.72) increase, compared to CON which had a 2.6% decrease.Conclusions
This study provides preliminary evidence that HIIT may be an effective exercise intervention to improve cognitive performance, cerebrovascular function and aerobic fitness in breast cancer survivors. Considering the sample size is small, these results should be confirmed through larger clinical trials. 相似文献15.

Objectives
The primary aim of this study was to evaluate the preliminary efficacy and feasibility of an 8-week high-intensity interval training program (Uni-HIIT) for young adult students in a university setting.Design
Randomised controlled trial.Method
Uni-HIIT was conducted at the University of Newcastle, Australia (February-June, 2017). Participants were university students 18-25yrs (n = 53; 20.38 ± 1.88yrs) randomized into the Uni HIIT program (n = 26) or wait-list control (n = 27) condition. Participants were required to attend up to three HIIT sessions/week for 8-weeks which included a variety of aerobic and muscular fitness exercise combinations lasting 8–12 minutes (using 30:30 sec rest:work intervals). The primary outcome was cardio-respiratory fitness (CRF) (20mSRT), and secondary outcomes included muscular fitness (standing jump, push-ups), body composition (InBody), executive function (Trail Making Test), anxiety levels (State Trait Anxiety Inventory) and perceived stress (Perceived Stress Scale). Linear mixed models were used to analyse outcomes and Cohen’s d effect sizes were calculated. Process evaluation measures of recruitment, retention, attendance and satisfaction were conducted.Results
A large significant group-by-time effect resulted for CRF [8.4 shuttles (95% CI(2.9-13.9), P = 0.004,d = 1.08] and muscular fitness [4.0 repetitions (95% CI(1.2-6.8), P = 0.006,d = 0.99], and moderate effect size was observed for Trail B [-5.9 seconds (95% CI(-11.8-0.1.0), P = 0.052, d = 0.63]. No significant intervention effects were found for body composition, standing jump, anxiety or perceived stress (P > 0.05). High ratings of participant satisfaction (4.73), enjoyment (4.54) and perceived value (4.54) were observed.Conclusion
This study demonstrates the efficacy and feasibility of delivering a novel HIIT program in the university setting. 相似文献16.

Purpose
To evaluate efficacy of cone-beam CT–based liver perfusion mapping obtained immediately following conventional transarterial chemoembolization of hepatocellular carcinoma (HCC) for assessing tumor vascularity, technical success of chemoembolization, and treatment response.Materials and Methods
From July 2015 to June 2016, 35 patients with 57 HCCs who underwent cone-beam CT with post-processing software via conventional transarterial chemoembolization for HCC and follow-up examination were included. Three reviewers evaluated technical success on angiography, unenhanced cone-beam CT, contrast-enhanced cone-beam CT, and cone-beam CT–based liver perfusion mapping after transarterial chemoembolization per tumor and per patient. Parenchymal blood volume (PBV) was measured. Treatment response was determined on follow-up CT, MR imaging, or histopathology according to modified Response Evaluation Criteria In Solid Tumors. Diagnostic performance for detection of a viable tumor was evaluated using multiple logistic regression with C-statistics.Results
Treatment response was 38, 17, 2, and 0 for complete response, partial response, stable disease, and progressive disease per tumor and 18, 15, 2, and 0 per patient. In multiple logistic regression, unenhanced cone-beam CT, contrast-enhanced cone-beam CT, cone-beam CT–based liver perfusion mapping, mean value of PBV, and maximum value of PBV of tumor were significant in response assessment for per tumor and per patient (per tumor, all P < .001; per patient, P = .015, P = .001, P < .001, P = .020, and P = .032). Mean value of PBV of tumor was excellent for evaluating technical success with the highest C-statistic (0.880 and 0.920 for per tumor and per patient), followed by that of visual assessment of cone-beam CT–based liver perfusion mapping (0.864 and 0.908).Conclusions
Cone-beam CT–based liver perfusion mapping provided reliable images to evaluate technical success after transarterial chemoembolization of HCC by qualitative visual assessment and quantitative perfusion values. 相似文献17.

Patients listed for liver transplantation for HCC (March 1998 to December 2010) undergoing LRT with available multiphase MR/CT imaging before transplantation were included. Pathologic response was evaluated based on liver explant pathology. A total of 108 patients (17 women; 16%) met the inclusion criteria.Results
Radiologic CR was achieved in 65 patients (60%) vs non-CR in 43 (40%), and pathologic CR was achieved in 36 patients (33%) vs non-CR in 72 (67%). Mean 5-year overall survival (OS) from the time of listing and recurrence-free survival (RFS) after liver transplantation were significantly better for patients with pathologic CR vs non-CR on explant pathology (OS, 83.3% vs 65.2% [28% difference; P = .046]; RFS, 80.6% vs 62.5% [29% difference; P = .045]). Mean 5-y OS and RFS were not significantly different between patients with radiologic CR or non-CR on pretransplantation imaging (OS, 75.4% vs 65.1% [P = .12]; RFS, 74% vs 62.8% [P = .17]).Conclusions
Achievement of a pathologic CR vs non-CR in response to LRT before liver transplantation for HCC is associated with improved OS from time of listing and improved RFS after liver transplantation. However, current imaging paradigms fall short of accurate delineation of response to LRT, resulting in poor correlation of outcomes between pathologic and radiologic CR. 相似文献18.

Purpose
To investigate the efficacy of palmar warming to induce radial artery vasodilation.Materials and Methods
After informed consent was obtained, healthy volunteers (n = 45) were randomized 2:1 in palmar warming and control groups, respectively, for this prospective, randomized, single-blind clinical trial (NCT03620383). The palmar warming group was given a warm, commercially available, air-activated heat pack (Kobayashi Consumer Products LLC, Dalton, Georgia) to hold in the left hand for palmar warming. The control group was given a deactivated version of the same heat pack. Left radial artery cross-sectional area (CSA) measurements were obtained at baseline and in 5-minute intervals up to 20 minutes in both groups. Differences in the trends of changes in the radial artery CSA between palmar warming and control groups were examined with the age- and sex-adjusted repeated measure analysis of variance. Propensity score-matched treatment effect analysis was conducted to quantify the effect of heat on radial artery CSA.Results
The palmar warming group and the control group were significantly different in terms of subject sex (males/females: 7/23 and 10/5, respectively; P = .005) and baseline CSA (2.5±0.2 mm2 vs 3.2±0.3 mm2, respectively; P = .014). Radial artery CSA showed an increasing trend over time in the palmar warming group compared to a stable trend over time in the control group (P < .0001). Propensity score-matched comparison showed a 43.9% increase (95% confidence interval: 34.1%–53.8%) in CSA in the palmar warming group compared to the control group (P < .0001).Conclusions
The palmar warming technique is effective at dilating the radial artery and may be a beneficial technique to facilitate transradial access. 相似文献19.

Objectives
The purpose of this study was to identify early life factors that were associated with childhood and adolescent organized sport participation trajectories.Design
Participants were in the Raine Study, a pregnancy cohort in Western Australia recruited from 1989 to 1991.Methods
Three organized sport trajectories over ages 5–17 years were previously identified for girls (n = 824: consistent participators, dropouts, and non-participators in sport) and boys (n = 855: consistent participators, dropouts, joiners — those who joined sport in adolescence). Physical, psychological and social factors were measured from birth to age 5.Results
For girls and boys, children who were breastfed, were taller, did not have behavior problems, and attended childcare were more likely to consistently participate. Girls who had a previous injury (Relative risk ratio 1.55: 95% confidence interval 1.05, 2.29 vs never been injured) or who had parents who had worries about their child’s health (1.56: 1.00, 2.42 vs no worries) were more likely to be in the dropout trajectory. Boys born preterm (2.00, 2.06, 3.76 vs full-term), did not have a previous injury (0.72, 0.53, 0.97 those with injury vs never been injured), had more difficult temperament (1.63, 1.02, 2.60 vs easy temperament), and higher family dysfunction (1.49, 1.06, 2.08) were more likely to be in the dropout trajectory.Conclusions
Early life factors were associated with membership in sport trajectories. Physical, psychological, and social factors may serve as early warning signs for parents and practitioners that children may be at higher risk of dropping out of sports. 相似文献20.
