Abstract
The material release on the side opposite to the laser drive of a CH shell was probed at conditions relevant to inertial confinement fusion. The release was found to expand further with a longer scale length than that predicted by radiation-hydrodynamic simulations. The simulations show that a relaxation of the back side of the shell consistent with measurements explains the experimentally observed reduction in inertial confinement fusion implosion performance-specifically, reduced areal density at peak compression.

Abstract
Abstract
Background
Regulatory approval of drugs and devices follow two different pathways. Whether different approval pathways underlie meaningful differences in quality of clinical trial evidence is unknown. We aimed to compare the quality of evidence of clinical trials that served as a basis for approval by the U.S. Food and Drug Administration (FDA) of drugs and devices used for the treatment of coronary artery disease.
Methods
FDA databases were searched for devices (i.e., coronary artery drug-eluting stents) and drugs (i.e., agents targeting atherothrombosis) approved between January 1st, 2001 and December 31st, 2017. FDA medical reviews were screened to identify trials that served for approval purposes. The pre-specified primary outcome was the prevalence of randomized trials used for approval (i.e. number of randomized trials/overall number of trials).
Results
A total of 97 trials were identified, 39 serving for approval of 13 devices and 58 serving for approval of 8 drugs. Devices were evaluated by fewer trials per item as compared with drugs (3.0±1.4 vs. 7.3±5.3, P=0.012) with similar study size (501 [100–1314] vs. 379 [183–904] patients per trial, P=0.55). Trials evaluating devices were less frequently randomized (56.4% vs. 94.8%, P<0.001) and more frequently designed powered for clinical endpoints (53.8% vs. 17.2%, P<0.001) as compared to those evaluating drugs. Use of randomization declined over time among trials supporting FDA approval of devices. In addition, significant differences were present between trials evaluating devices and those evaluating drugs in terms of study design, comparator used, blinding to treatment allocation, primary hypothesis, primary endpoint, and type of patients included.
Use of randomized trials for approval
Conclusions
There are substantial differences in clinical trial evidence serving for FDA approval of devices and drugs used for treatment of coronary artery disease. The lower degree of randomized evidence used for approval of devices as compared to drugs raises some concerns, particularly in view of its decline over time.

Abstract
Abstract
Background
Stroke represents a potentially calamitous complication among patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) even though its rates are relatively low. Data on the distribution of stroke occurrence over time and its overlap with myocardial infarction (MI) and bleeding after PCI is scarce.
Purpose
We sought to compare the occurrence and impacts of stroke, MI and bleeding on subsequent mortality in ACS patients undergoing PCI in contemporary clinical practice.
Methods
A total of 19,914 ACS patients who underwent PCI in the PROMETHEUS multi-center observational study were analyzed. We calculated the cumulative stroke incidence at 30 days and 1 year using Kaplan Meier (KM) method. We also compared the distribution of stroke, myocardial infarction (MI) and bleeding across time and evaluated the overlap between their occurrences. Predictors of 1 year stroke occurrence were identified through multivariable Cox-regression and stroke, MI and bleeding were entered as time-updated covariates to estimate their individual effects on subsequent mortality.
Results
Of the total number of patients, 244 patients (1.5%) had a stroke within 1 year. 48 of these patients also experienced an MI while another 48 patients experienced a bleeding event. Furthermore, 14 of these overlapping patients experienced a stroke, MI and bleeding event, all within the 1-year follow-up. Patients who sustained a stroke were more likely to have a prior history of cerebrovascular disease, peripheral artery disease, MI and heart failure compared to those who did not have a stroke. Mortality risk was significantly higher among those with stroke versus those without stroke (adjusted HR 4.84, p<0.0001). However, the association attenuated over time with a much larger effect in the first 30 days of its occurrence (adjusted HR 17.7, p<0.0001) versus beyond 30 days (adjusted HR 1.22; 95% CI: 0.6–2.46, p=0.58). Although the effects of MI and bleeding on subsequent mortality within 30 days of occurrence were significantly lower than stroke (adjusted HR 6.22, p<0.0001; adjusted HR 7.30, p<0.0001, respectively), their effects were more sustained on mortality beyond 30 days (adjusted HR 2.89, p<0.0001; adjusted HR 3.05, p<0.0001, respectively).
Conclusion
When compared with MI and bleeding, stroke had a substantially stronger impact on mortality that attenuated rapidly over time among ACS patients undergoing PCI. Optimization of modifiable risk factors and medication adherence are essential parts of management of stroke following PCI for ACS.

Abstract
This Letter reports the first extraction of individual antineutrino spectra from ^{235}U and ^{239}Pu fission and an improved measurement of the prompt energy spectrum of reactor antineutrinos at Daya Bay. The analysis uses 3.5×10^{6} inverse beta-decay candidates in four near antineutrino detectors in 1958 days. The individual antineutrino spectra of the two dominant isotopes, ^{235}U and ^{239}Pu, are extracted using the evolution of the prompt spectrum as a function of the isotope fission fractions. In the energy window of 4-6 MeV, a 7% (9%) excess of events is observed for the ^{235}U (^{239}Pu) spectrum compared with the normalized Huber-Mueller model prediction. The significance of discrepancy is 4.0σ for ^{235}U spectral shape compared with the Huber-Mueller model prediction. The shape of the measured inverse beta-decay prompt energy spectrum disagrees with the prediction of the Huber-Mueller model at 5.3σ. In the energy range of 4-6 MeV, a maximal local discrepancy of 6.3σ is observed.

Abstract
PURPOSE This study aimed to determine if the prognoses of inguinal hernia patients improved with the application of lightweight mesh (LWM). METHODS Medline, Embase, and Cochrane library were searched for randomized controlled trails related to laparo-endoscopic inguinal hernia repair with different prosthetic meshes. Data were extracted and analyzed using the guidelines of the Cochrane handbook. The primary endpoints were recurrence and chronic postoperative inguinal pain. The second endpoints encompassed acute postoperative pain, foreign body sensation, seroma, infection, and numbness. Data were processed using Review Manager 5.3. RESULTS The heavyweight mesh (HWM) had a distinctive advantage for recurrence (RR 2.30; 95% CI 1.21-4.38; P = 0.01), with comparable results for postoperative pain (RR 0.91; 95% CI 0.37-2.22; P = 0.83), foreign body sensation (RR 1.18; 95% CI 0.91-1.51; P = 0.21), seroma(RR 0.87; 95% CI 0.75-1.01; P = 0.06), infection (RR 0.85; 95% CI 0.31-2.34; P = 0.75), and numbness, compared to LWM. CONCLUSION HWM had a distinctive advantage over LWM with regard to recurrence. The two types of prosthetic meshes had equivalent outcomes for postoperative pain, seroma, foreign body sensation, infection, and numbness. Studies focused on defect sizes and fixation methods are warranted for further stratification.

Abstract
OBJECTIVES The use of combination antiretroviral therapy (cART) increases clinical uncertainty about changes in renal function. Specifically, little is known regarding the interaction of the effects of aging, baseline renal impairment, and stages of HIV infection on post-treatment changes in renal function. METHODS This analysis included 5533 HIV-infected patients on cART in 2004-2016. Progression to chronic kidney disease (CKD) was defined as either two consecutive estimated glomerular filtration rate (eGFR) measurements < 60 mL/min/1.73 m2 for baseline eGFR ≥ 60 mL/min/1.73 m2 (mild renal impairment or normal renal function) or a 25% decline for baseline eGFR < 60 mL/min/1.73 m2 (moderate renal impairment). RESULTS During follow-up (median 4.8 years), 130 (2.3%) of the patients progressed to CKD. A total of 20.1% of patients with baseline normal renal function progressed to mild renal impairment, while 74.0% of patients with baseline mild or moderate renal impairment improved to normal renal function. In multivariable analysis, a significant positive baseline-eGFR-by-World Health Organization (WHO)-stage interaction effect on progression to CKD in all patients was identified, indicating a cross-over effect from a reduced risk to an increased risk. A significant negative baseline-age-by-WHO-stage interaction effect on progression to mild renal impairment in patients with baseline normal renal function was identified, with adjusted hazard ratios progressively lower at older ages. In addition, there were significant associations with older age, lower baseline eGFR, Dai ethnic minority, and anaemia for both outcomes, hyperglycaemia for CKD only, and higher CD4 count, tenofovir and ritonavir-boosted lopinavir use for mild renal impairment only. CONCLUSIONS Our data suggest a complex pattern of renal function dynamics in patients on cART, which requires precise management with systematic monitoring of the interaction of the effects of sociodemographic, nephrological and HIV-specific clinical characteristics.

Abstract
Objective: To investigate the risk factors affecting the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF), and establish a new scoring model to predict the short-term prognosis of patients. Methods: This study enrolled 222 patients with HBV-ACLF. According to their clinical outcomes during hospitalization and 90 days after discharge, they were divided into survival and death group. Clinical data were collected to calculate the Child-Turcotte-Pugh (CTP), model for end-stage liver disease (MELD), albumin-bilirubin (ALBI), and age-bilirubin-international normalized ratio-creatinine (ABIC) scores for prognosis. Multivariate logistic regression analysis was used to analyze the independent risk factors affecting 90-day mortality in HBV-ACLF patients. Cox regression model was used to establish a new prediction model. Area under the receiver operating characteristic curve was used to calculate short-term prognostic value of the models. K-M survival curve was used to predict the prognosis of patients. Results: CTP and ABIC scores were independent risk factors for 90-day mortality in HBV-ACLF patients, and the risk of death from liver failure had increased with increase of score. Cox regression model established a new predictive model CTP-ABIC = 0.551 × CTP + 0.297 × ABIC. Area under the receiver operating characteristic curve of all three scoring models (CTP, ABIC and CTP-ABIC) were 0.878, 0.829, 0.927, respectively. CTP-ABIC score was superior to the CTP and ABIC score (P value < 0.001). Patients with CTP-ABIC score ≥9.08 had higher mortality rate than patients with CTP-ABIC score < 9.08, and the difference was statistically significant (P < 0.001). Conclusion: All three scoring systems can predict short-term prognosis in patients with HBV-ACLF, but the accuracy of CTP-ABIC is superior.

Abstract
Focusing laser light onto a very small target can produce the conditions for laboratory-scale nuclear fusion of hydrogen isotopes. The lack of accurate predictive models, which are essential for the design of high-performance laser-fusion experiments, is a major obstacle to achieving thermonuclear ignition. Here we report a statistical approach that was used to design and quantitatively predict the results of implosions of solid deuterium-tritium targets carried out with the 30-kilojoule OMEGA laser system, leading to tripling of the fusion yield to its highest value so far for direct-drive laser fusion. When scaled to the laser energies of the National Ignition Facility (1.9 megajoules), these targets are predicted to produce a fusion energy output of about 500 kilojoules-several times larger than the fusion yields currently achieved at that facility. This approach could guide the exploration of the vast parameter space of thermonuclear ignition conditions and enhance our understanding of laser-fusion physics.

Abstract
We report a measurement of electron antineutrino oscillation from the Daya Bay Reactor Neutrino Experiment with nearly 4 million reactor ν[over ¯]_{e} inverse β decay candidates observed over 1958 days of data collection. The installation of a flash analog-to-digital converter readout system and a special calibration campaign using different source enclosures reduce uncertainties in the absolute energy calibration to less than 0.5% for visible energies larger than 2 MeV. The uncertainty in the cosmogenic ^{9}Li and ^{8}He background is reduced from 45% to 30% in the near detectors. A detailed investigation of the spent nuclear fuel history improves its uncertainty from 100% to 30%. Analysis of the relative ν[over ¯]_{e} rates and energy spectra among detectors yields sin^{2}2θ_{13}=0.0856±0.0029 and Δm_{32}^{2}=(2.471_{-0.070}^{+0.068})×10^{-3} eV^{2} assuming the normal hierarchy, and Δm_{32}^{2}=-(2.575_{-0.070}^{+0.068})×10^{-3} eV^{2} assuming the inverted hierarchy.

Abstract
Nonlocal heat flux was measured in laser-produced coronal plasmas using a novel Thomson scattering technique. The measured heat flux was smaller than the classical values inferred from the measured plasma conditions in regions with large temperature gradients and agreed with classical values for weak gradients. Vlasov-Fokker-Planck simulations self-consistently calculated the electron distribution functions used to reproduce the measured Thomson scattering spectra and to determine the heat flux. Multigroup nonlocal simulations overestimated the measured heat flux.

Abstract
BACKGROUND AND PURPOSE Anaplastic pleomorphic xanthoastrocytoma, which has been recently defined as a distinct entity in the 2016 World Health Organization classification, may exhibit aggressive clinical behavior and relatively worse prognosis than pleomorphic xanthoastrocytoma. This study aimed to investigate whether there were any differences in MR imaging characteristics between these 2 tumors. MATERIALS AND METHODS This retrospective study included 9 patients with anaplastic pleomorphic xanthoastrocytoma and 10 patients with pleomorphic xanthoastrocytoma who underwent MR imaging before an operation. DWI was performed in 17 patients (8 with anaplastic pleomorphic xanthoastrocytoma, 9 with pleomorphic xanthoastrocytoma); and DSC-PWI, in 9 patients (5 with anaplastic pleomorphic xanthoastrocytoma, 4 with pleomorphic xanthoastrocytoma). Demographics, conventional imaging characteristics (location, size, cystic degeneration, enhancement, peritumoral edema, and leptomeningeal contact), minimum relative ADC ratio, and maximum relative CBV ratio were evaluated between the anaplastic pleomorphic xanthoastrocytoma and pleomorphic xanthoastrocytoma groups. RESULTS Anaplastic pleomorphic xanthoastrocytoma was more likely to demonstrate high-grade features than pleomorphic xanthoastrocytoma, including greater maximum tumor diameter (4.7 ± 0.6 cm versus 3.1 ± 1.1 cm, P = .001), more frequent heterogeneous contrast enhancement of solid portions (88.9% versus 20.0%, P = .01), more obvious peritumoral edema (2.3 ± 0.9 cm versus 1.0 ± 0.9 cm, P = .008), lower minimum relative ADC on DWI (1.0 ± 0.2 versus 1.5 ± 0.4, P = .008), and higher maximum relative CBV on DSC-PWI (2.6 ± 0.8 versus 1.6 ± 0.2, P = .036). CONCLUSIONS Anaplastic pleomorphic xanthoastrocytomas often have more aggressive MR imaging features mimicking high-grade astrocytomas than pleomorphic xanthoastrocytomas. DWI and DSC-PWI might be useful in the characterization and differentiation of anaplastic pleomorphic xanthoastrocytoma and pleomorphic xanthoastrocytoma.

Abstract
Background To identify baseline/clinical characteristics associated with clinically meaningful responses to insulin glargine 100 U/mL (IGlar) in insulin-naive people with type 2 diabetes mellitus (T2DM). Methods Individual participant data were pooled from 3 randomized trials to compare baseline characteristics and clinical outcomes associated with 24-week response to IGlar in combination with non-insulin antihyperglycemic agents in participants with T2DM. Responders were defined as achieving endpoint HbA1c target < 53 mmol/mol (< 7%) and/or ≥ 11 mmol/mol (≥ 1%) HbA1c reduction from baseline. Results Differences in baseline characteristics for responders versus nonresponders were higher HbA1c (99 vs 91 mmol/mol [9.1 vs 8.3%]; P < 0.001), higher fasting blood glucose (FBG; 10.4 vs 8.8 mmol/L [187 vs 159 mg/dL; P < 0.001), and fewer participants (94% vs 98%; P = 0.006) taking oral medications targeting postprandial blood glucose (BG). Most participants (80%) achieved one or both components of composite endpoint. 12-week response was a strong predictor of subsequent 24-week response (sensitivity, 85.9%; predictive positive value, 91.4%). At both 12 and 24 weeks, < 40% of responders and nonresponders reached target FBG ≤ 5.6 mmol/L (≤ 100 mg/dL). Responders at 24 weeks had higher incidence of hypoglycemia (total, 82.5% vs 70.4%; P < 0.001; nocturnal, 60.3% vs 50.5%; P = 0.002; documented symptomatic, 65.8% vs 55.6%; P < 0.001) than nonresponders. Conclusions Baseline characteristics associated with response were identified. The strong predictability of 12-week response suggests that the magnitude of early HbA1c reduction should be considered when assessing response to IGlar. More aggressive IGlar titration may be reasonable for nonresponders and responders who have not reached FBG and HbA1c targets, taking into account other BG timepoints.

Abstract
OBJECTIVES We aimed to evaluate the relationship between baseline renal function and changes in telomere length in Han Chinese. METHODS The telomere restriction fragment (TRF) length of leukocytes in the peripheral blood was measured in healthy volunteers recruited in 2014. The estimated glomerular filtration rate (eGFR) was calculated based on serum creatinine (Scr) and serum cystatin C (CysC)-eGFRcys and eGFRScr-cys through the Cockcroft-Gault formula (eGFRC-G) or the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI / eGFRCKD-EPI) equation. The correlation between telomere length changes over time and renal function was analyzed. RESULTS Leukocyte TRF lengths were negatively correlated to age (r = -0.393, p < 0.001) and serum CysC (r = -0.180, p < 0.01), while positively associated with eGFRCKD-EPI, eGFRC-G, eGFRcys, and eGFRScr-cys (r = 0.182, 0.122, 0.290, and 0.254 respectively, p < 0.01). The 3-year change of telomere length was 46 bp/years. When adjusted for age, the associations between telomere length changes and baseline, subsequent TRF lengths, and serum CysC were no longer present. No association was observed between TRF length changes and renal function. CONCLUSION The rate of telomere length changes was affected by age and baseline telomere length. The telomere length changes might be important markers for aging.
