INTRODUCTION:
Gastrointestinal endoscopic quality is operator-dependent. To ensure the endoscopy quality, we constructed an endoscopic audit and feedback system named Endo.Adm and evaluated its effect in a form of pretest and posttest trial.

METHODS:
Endo.Adm system was developed using Python and Deep Convolutional Neural Ne2rk models. Sixteen endoscopists were recruited from Renmin Hospital of Wuhan University and were randomly assigned to undergo feedback of Endo.Adm or not (8 for the feedback group and 8 for the control group). The feedback group received weekly quality report cards which were automatically generated by Endo.Adm. We then compared the adenoma detection rate (ADR) and gastric precancerous conditions detection rate between baseline and postintervention phase for endoscopists in each group to evaluate the impact of Endo.Adm feedback. In total, 1,191 colonoscopies and 3,515 gastroscopies were included for analysis.

RESULTS:
ADR was increased after Endo.Adm feedback (10.8%–20.3%, P < 0.01, <odds ratio (OR) 2.13, 95% confidence interval (CI) 1.317–3.447), and endoscopists' ADR without feedback remained nearly unchanged (10.8%–10.9%, P = 0.57, OR 1.086, 95% CI 0.814–1.447). Gastric precancerous conditions detection rate increased in the feedback group (3%–7%, P < 0.01, OR 1.866, 95% CI 1.399–2.489) while no improvement was observed in the control group (3.9%–3.5%, P = 0.489, OR 0.856, 95% CI 0.550–1.332).

DISCUSSION:
Endo.Adm feedback contributed to multifaceted gastrointestinal endoscopic quality improvement. This system is practical to implement and may serve as a standard model for quality improvement in routine work (http://www.chictr.org.cn/, ChiCTR1900024153).

Abstract
Hill, MW, Roberts, M, Price, MJ, and Kay, AD. Effects of flywheel training with eccentric overload on standing balance, mobility, physical function, muscle thickness, and muscle quality in older adults. J Strength Cond Res 36(11): 3190–3199, 2022—This study investigated the effects of a 6-week eccentric overload flywheel training program on vastus lateralis (VL) and gastrocnemius medialis (GM) muscle thickness and muscle quality (echo intensity), mobility (Timed Up and Go [TUG]), physical function (sit-to-stand), and balance (postural sway) performance. Nineteen subjects were assigned to either a flywheel training group (n = 11, age = 66.4 ± 5.2 years) or a control group (n = 8, age = 65.9 ± 3.8 years). The flywheel group underwent twice weekly squat and calf raise exercises for 6 weeks with outcome measures assessed before and after training or a time-matched control period. Throughout the training, subjects were instructed to contract as fast as possible with maximal effort during the concentric phase and to maximally resist the pull during the eccentric phase. The alpha value was a priori set at p < 0.05. Statistically significant (p < 0.05) mean (SD) increases in right and left VL (7.6–9.6 ± 7.7–9.8%) and GM (8.6–8.7 ± 6.4–11.5%) muscle thickness and a reduction in VL (10.2–11.3 ± 5.9–7.9%) and GM (11.7–11.9 ± 5.6–9.6%) echo intensity were accompanied by faster TUG time (13.7 ± 7.0%) improved sit-to-stand performance (17.8–23.5 ± 7.6 – 13.4%) and reduced postural sway (29.7–42.3 ± 13.2–24.2%) after 6 weeks of flywheel training. There were no differences in any outcome measures between the treatment and control group at baseline (p > 0.05). Overall, we observed substantial gains in muscle thickness and muscle quality, in addition to enhanced physical function, balance, and mobility performance among older adults after flywheel training, which may have important implications for preserving the functional capacity of older adults.

Sitko, S, Cirer-Sastre, R, Corbi, F, and López-Laval, I. Functional threshold power as an alternative to lactate thresholds in road cycling. J Strength Cond Res 36(11): 3179–3183, 2022—This study assessed the relationship between functional threshold power (FTP) and 7 lactate landmarks (Dmax, modified Dmax, fixed blood lactate concentrations of 2 and 4 mmol·L−1, lactate increases of 1 and 2 mmol·L−1 above baseline, and lactate increases of 1.5 mmol·L-1 above the point of minimum ratio between lactate and work rate) in a sample of 46 road cyclists with a wide range of fitness levels (age 38 ± 9 years, height 177 ± 9 cm, body mass 71.4 ± 8.6 kg, body mass index 22.7 ± 2.2 kg·m−1, fat mass 7.8 ± 4%, and V̇o
2max = 61.1 ± 9.1 ml·min−1·kg−1). The cyclists performed a graded exercise test in which power outputs (POs) at the lactate landmarks were identified. Functional threshold power was established as 95% of the PO during a 20-minute test. Significance was set as p < 0.05. Statistical analyses revealed large to very large correlations between PO, relative PO (RPO), and cadence at FTP and lactate thresholds (LTs) established through Dmax, modified Dmax, and fixed lactate concentrations of 4 mmol·L−1 (r = 0.68–0.93). Significant differences (p < 0.001) were also observed for PO and RPO at FTP, fixed blood lactate concentrations of 2 mmol·L−1, and lactate increases of 1 mmol·L−1 above baseline. Therefore, although FTP estimated from a 20-minute test is strongly related to several lactate landmarks, caution is required when substituting this concept for LTs. This information will allow coaches, cyclists, and scientists to better choose assessments when attempting to estimate LT through power-based field testing.

Objective
GC/DBP effects on response to vitamin D supplementation have not been well-studied. Thus we assessed free and total 25-OHD after vitamin D treatment across the six common GC haplotypes.

Design
This double-blind, randomized study compared two vitamin D3 doses in healthy, urban-dwelling 6-month to 10-year-old children at-risk for vitamin D deficiency. Randomization was stratified by GC haplotype.

Methods
Children were randomized to receive 2800 or 7000 International Units of vitamin D3 weekly. 25-OHD and 1,25(OH)2D were sampled at baseline and after 1–6 months of supplementation.

Results and conclusions
One hundred ninety-two of 225 enrolled subjects completed the study. After one month, total 25-OHD increased with both doses and were higher with 7000 IU/week (85.5 ± 22.8 nmol/L) compared to 2800 IU/week (76.8 ± 18.0 nmol/L), despite equivalent baseline levels. No further significant increase occurred at 6 months (89.8 ± 35.5 and 74.3 ± 18.3 nmol/L, respectively). Free 25-OHD similarly changed. 25-OHD differed among GC groups at baseline. Although no significant effects of individual GC haplotypes on incremental changes were evident, a trend toward an effect of combined 'at risk' GC alleles on response was evident (P = 0.06). Total 1,25(OH)2D showed modest increases, moreso with the larger dose. In urban-dwelling children at-risk for vitamin D deficiency, 1 month of vitamin D3 2800 IU/week increased 25-OHD across all GC haplotype groups, and somewhat enhanced with 7000 IU/week with no further significant increases after 6 months of supplementation. Free 25-OHD measures offer no monitoring advantage over total 25-OHD.
Correction ofP/SAmplitude Ratios for Low-Magnitude Seismic Events Based on Bayesian Kriging Method

Published: June 2021

ABSTRACTClassification of low-magnitude seismic events is a challenging issue for the Comprehensive Nuclear-Test-Ban Treaty. Path correction of the P/S amplitude ratio is the key to identifying earthquakes and explosions. In this article, the Bayesian Kriging interpolation method is used to conduct the path correction of P/S amplitude ratios and recognition of low-magnitude seismic events. Based on a total of 5677 small earthquakes and 1769 explosions in Beijing and its adjacent areas, the Bayesian Kriging method is used to establish the path correction surface and uncertainty surface of Pg/Lg amplitude ratios measured within different frequency bands at five seismic stations, and path correction of amplitude ratios is conducted for all events. The results show that the correction surface is consistent with the observed amplitude ratios, which can reflect the differences in their propagation paths to a certain extent. The root mean square variation of the amplitude ratio is reduced by a maximum of 30% and the misclassification probability is reduced by a maximum of 8.5% after the Kriging correction. The high-frequency Pg/Lg amplitude ratios can effectively classify low-magnitude events, and the misclassification probability at each station is less than 15% and 10% based on high-frequency Pg/Lg of &gt;7 and &gt;9  Hz, respectively. Of the five stations, BJT (Baijiatuan, Beijing) has the best recognition, with the misclassification probability being lower than 5% after Kriging correction based on high-frequency Pg/Lg (&gt;9  Hz). The classification ability of high-frequency amplitude ratios (&gt;15  Hz) is weakened due to high-frequency noises. Bayesian Kriging correction can reduce the variance in the amplitude ratio of low-magnitude seismic events and hence effectively improve the ability to classify small-magnitude events, which has an important reference value for regional seismic monitoring and identification.
Smooth Crustal Velocity Models Cause a Depletion of High-Frequency Ground Motions on Soil in 2D Dynamic Rupture Simulations
Authors: Huang Yihe 
Published: June 2021

ABSTRACTA depletion of high-frequency ground motions on soil sites has been observed in recent large earthquakes and is often attributed to a nonlinear soil response. Here, I show that the reduced amplitudes of high-frequency horizontal-to-vertical spectral ratios (HVSRs) on soil can also be caused by a smooth crustal velocity model with low shear-wave velocities underneath soil sites. I calculate near-fault ground motions using both 2D dynamic rupture simulations and point-source models for both rock and soil sites. The 1D velocity models used in the simulations are derived from empirical relationships between seismic wave velocities and depths in northern California. The simulations for soil sites feature lower shear-wave velocities and thus larger Poisson’s ratios at shallow depths than those for rock sites. The lower shear-wave velocities cause slower shallow rupture and smaller shallow slip, but both soil and rock simulations have similar rupture speeds and slip for the rest of the fault. However, the simulated near-fault ground motions on soil and rock sites have distinct features. Compared to ground motions on rock, horizontal ground acceleration on soil is only amplified at low frequencies, whereas vertical ground acceleration is deamplified for the whole frequency range. Thus, the HVSRs on soil exhibit a depletion of high-frequency energy. The comparison between smooth and layered velocity models demonstrates that the smoothness of the velocity model plays a critical role in the contrasting behaviors of HVSRs on soil and rock for different rupture styles and velocity profiles. The results reveal the significant role of shallow crustal velocity structure in the generation of high-frequency ground motions on soil sites.

ABSTRACTWe document the first use of fragile geologic features (FGFs) to set formal design earthquake motions for a major existing engineered structure. The safety evaluation earthquake (SEE) spectrum for the Clyde Dam, New Zealand (the mean 10,000 yr, ka, return period response spectrum) is developed in accordance with official guidelines and utilizes constraints provided by seven precariously balanced rocks (PBRs) located 2 km from the dam site and the local active Dunstan fault. The PBRs are located in the hanging wall of the fault. Deterministic PBR fragilities are estimated from field measurements of rock geometries and are the dynamic peak ground accelerations (PGAs) required for toppling. PBR fragility ages are modeled from B10e cosmogenic isotope exposure dating techniques and are in the range of 24–66 ka. The fragility ages are consistent with the PBRs having survived at least two large Dunstan fault earthquakes. We develop a PGA-based fragility distribution from all of the PBRs, which represents the cumulative toppling probability of a theoretical random PBR as a function of PGA. The fragility distribution is then used to eliminate logic-tree branches that produce PGA hazard curves that would topple the random PBR with a greater than 95% probability (i.e., less than 5% survival probability) over a time period of 24 ka (youngest PBR fragility age). The mean 10 ka spectrum of the remaining hazard estimates is then recommended as the SEE spectrum for the dam site. This SEE spectrum has a PGA of 0.55g, which is significantly reduced from the 0.96g obtained for a preliminary version of the SEE spectrum. The reduction is due to the combined effects of the PBR constraints and a substantial update of the probabilistic seismic hazard model. The study serves as an important proof-of-concept for future applications of FGFs in engineering design.

Published: June 2021

This study aims to examine and analyze the effect of store image on the repurchase intention of Matahari Department Store Mojokerto, Indonesia either directly or indirectly, by involving perceived value and customer satisfaction as mediating variables. This research is a quantitative study with data collection methods using a questionnaire. This study uses non-probability sampling with a purposive sampling type. This research was conducted on 175 respondents. The data analysis technique used SEM (Structural Equation Modeling) PLS with the help of SmartPLS 3.2.7 software. The results of the study provide empirical evidence that store images have not been able to affect the repurchase intention. Meanwhile, the perceived value and customer satisfaction can positively affect the repurchase intention significantly. Perceived value and customer satisfaction as mediating variables were able to strengthen the effect of store image on repurchase intention. Based on the results of mediation testing, shows that perceived value and customer satisfaction provide a full mediation on the effect of store image on repurchase intention.

Published: June 2021

Background:
Previous studies have identified risk factors for different types of treatment of proximal humeral fracture (PHF) and allowed the development of a patient-specific, evidence-based treatment algorithm with the potential of improving overall outcomes and reducing complications. The purpose of this study was to evaluate the results and complications of treating PHF using this algorithmic approach.

Methods:
All patients with isolated PHF between 2014 and 2017 were included and prospectively followed. The initial treatment algorithm (Version 1 [V1]) based on patients’ functional needs, bone quality, and type of fracture was refined after 2 years (Version 2 [V2]). Adherence to protocol, clinical outcomes, and complications were analyzed at a 1-year follow-up.

Results:
The study included 334 patients (mean age, 66 years; 68% female): 226 were treated nonoperatively; 65, with open reduction and internal fixation (ORIF); 39, with reverse total shoulder arthroplasty (RTSA); and 4, with hemiarthroplasty. At 1 year, the preinjury EuroQol 5-Dimension (EQ-5D) values were regained (0.88 and 0.89, respectively) and the mean relative Constant Score (CS) and Subjective Shoulder Value (SSV) (and standard deviation [SD]) were 96% ± 21% and 85% ± 16%. Overall complications and revision rates were 19% and 13%. Treatment conforming to the algorithm outperformed non-conforming treatment with respect to relative CS (97% versus 88%, p = 0.016), complication rates (16.3% versus 30.8%, p = 0.014), and revision rates (10.6% versus 26.9%, p < 0.001).

Conclusions:
Treating PHF using a patient-specific, evidence-based algorithm restored preinjury quality of life as measured with the EQ-5D and approximately 90% normal shoulders as measured with the relative CS and the SSV. Adherence to the treatment algorithm was associated with significantly better clinical outcomes and substantially reduced complication and revision rates.

Abstract
Background Antenatal depression is the most common psychiatric disorder during pregnancy and it’s associated with psychosocial and obstetric factors. Antenatal depression has serious consequences for the mother and fetus, such as recurrent spontaneous abortions, pregnancy induced hypertension, pre-eclampsia, postpartum bleeding, pre-term delivery, postnatal depressive disorders and low birth weight. However it doesn’t get appropriate attention.Methods Institutional based cross-sectional study design was conducted on 446 pregnant women coming for antenatal care service at Jinka public health facilities, from June 01 to June 30, 2018. Data was collected through semi-structured and pretested questionnaire by face to face interview technique and Beck Depression Inventory was used to assess women’s depression condition. Collected data was entered in to Epi data version 3.3.1 after checking their completeness and exported to statistical package for social science version 20.0 for analysis. Logistic regression was used to find out association between explanatory and response variables. Explanatory variables which fulfill the assumption of logistic regression and had P-value less than 0.25 from bi-variable logistic regression were considered for the multivariable logistic regression model. Strength of association was evaluated using odds ratio at 95% confidence interval and P-value < 0.05 was considered to declare significant associations.Result The magnitude of antenatal depression in this study was 24.4%(20.2-28.5 at 95% CI) and it had statistically significant association with unmarried marital status AOR =13.39 [(95%CI); (3.11-57.7)], chronic medical illness AOR=3.97 [(95%CI); (1.07-14.7)], unplanned pregnancy AOR =6.76 [ (95%CI); (2.13-21.4)], history of abortion AOR =2.8 [(95%CI); (1.14-7.02)], history of previous pregnancy complication AOR =4.8 [(95%CI); (2.12-17.35)] and fear of pregnancy related complications AOR=5.4 [(95%CI); (2.32-12.4)].Conclusion and recommendation The magnitude of antenatal depression was high. So integrating mental health service in antenatal care assessment, provide comprehensive family planning service and improve obstetric service are recommended.

Published: June 2021

Abstract
Super-resolution methods have been developed to overcome physical diffraction limits of optical and ultrasound imaging techniques. Hybrid optoacoustic imaging approaches share the rich functional and molecular contrast advantages of optical methods while additionally attaining centimeter-scale penetration into living tissues due to reduced ultrasound scattering. The application of super-resolution principles for enhancing the optoacoustic imaging performance deep in mammalian tissues has so far been impeded by the high density of strongly absorbing red blood cells. Herein, we demonstrate three-dimensional microangiography of deep mouse brain beyond the acoustic diffraction limit (<20 µm resolution) through the intact scalp and skull via optoacoustic localization of sparsely-distributed highly absorbing microparticles. This was enabled by devising 5 µm sized extremely absorbing dichloromethane microdroplets exhibiting four orders of magnitude higher optical absorption than red blood cells at near-infrared wavelengths, thus facilitating in vivo compatibility and single particle sensitivity in the presence of highly absorbing blood background. Accurate mapping of the blood flow velocity within microvascular structures was also accomplished with a dedicated high-frame-rate volumetric optoacoustic tomography system. We further show that the detected optoacoustic signal intensities from the localized particles may serve for estimating the light fluence distribution within optically heterogeneous tissues, a long-standing quantification challenge in biomedical optics. Given the intrinsic sensitivity of optoacoustics to various functional, metabolic and molecular events in living tissues, this new approach paves the way for non-invasive deep-tissue microscopic observations with unrivaled resolution, contrast and speed.
