Growing high quality silicon nanowires (SiNWs) at elevated temperature on cooler polymer films seems to be contradictive but highly desirable for building high performance flexible and wearable electronics. In this work, we demonstrate a superfast (vnw > 3.5 μm·s-1) growth of high quality SiNWs on polymer/glass substrates, powered by self-selected laser at 808 nm heating of indium catalyst droplets that absorb amorphous Si layer to produce SiNWs. selleck Because of the tiny heat capacity of the nanodroplets, the SiNW growth can be quickly heated up and frozen via rapid laser ON/OFF switching, enabling a deterministic diameter modulation in the ultralong SiNWs. Finally, prototype field effect transistors are also fabricated upon the laser-droplet-heating grown SiNWs with a high Ion/Ioff ratio of >104 and reasonable subthreshold swing of 386 mV·dec-1, opening a generic new route to integrate high-quality NW channels directly upon large area and lightweight polymer substrates for developing high-performance flexible electronics.

Female farmers commonly experience musculoskeletal pain in the back, knee, and shoulder. Despite their obvious advantages in reducing musculoskeletal pain, face-to-face exercise programs are limited by geographical and physical barriers. Thus, we decided to introduce eHealth technology to farmers' musculoskeletal health care. Using a mobile application (app), we aim to provide a tailored self-exercise program for shoulder, knee, and back pain in female farmers in rural areas after a musculoskeletal health check-up.

This study is planned as 2 randomized control studies (MObile Delivered self-Exercise [MODE] phase I and phase II). We plan to recruit 200 female farmers aged 41 to 70 years. Initially, the shoulders, knees, and low back will be evaluated to provide individualized exercise programs. In MODE-I (single-blinded evaluator), the subjects will be randomly allocated to experimental (n = 100) and control (n = 100) groups using a computer-generated sequence. Both groups will perform a 3-month self-exerc to the degree of participation over 12 months to confirm the effect of self-exercise. Our study should aid in managing musculoskeletal health for farmers living in rural areas and help promote health in the "untact" era.

Jehovah's Witnesses (JWs) refuse blood transfusions due to religious issues. This situation may impact kidney transplantation (KT) outcomes in case of hemorrhagic complications. We evaluated demographic characteristics of this population, hematologic safety, and graft outcomes.

This was a retrospective, single-center study comparing KT outcomes in JW patients versus a non-JW control group. Hematologic endpoints included clinical indication for blood transfusion (hemoglobin <7 g/dL), decrease of hemoglobin >2 g/dL or hematocrit >5% in the first week after KT, hemorrhagic complications requiring surgery, and de novo prescription of erythropoiesis-stimulating agents. Secondary endpoints included delayed graft function, treated biopsy-proven acute rejection, renal function, mortality, and graft survival at 12 months.

From January 1989 to September 2018, we identified 143 JW (10 pediatric) and selected 142 matched control (non-JW) patients. There were no differences in the incidence of clinical indiduring the first year after transplantation compared with non-JW patients.

The effects of atrial fibrillation (AF) catheter ablation on the left atrium (LA) are poorly understood.

To examine short- and long-term associations of AF catheter ablation with LA function using cardiac magnetic resonance (CMR).

Fifty-one AF patients (mean age 56 ± 8 years) underwent CMR at baseline, 1 day (n = 17) and 11 ± 2 months after ablation (n = 38). LA phasic volumes, emptying fractions (LAEF), and longitudinal strain were measured using feature-tracking CMR. LA fibrosis was quantified using late gadolinium enhancement (LGE).

There were no acute changes in volume; however, active, total LAEF, and peak LA strain decreased significantly compared to the baseline. During long-term follow-up, there was a decrease in maximum but not minimum LA volume (from 99 ± 5.2 ml to 89 ± 4.7 ml; p = .009) and a decrease in total LAEF (from 43 ± 1.8% to 39 ± 2.0%; p = .001). In patients with AF recurrence, LA volumes were unchanged. However, total LAEF decreased from 38 ± 3% to 33 ± 3%; p = .015. Patients without AF recurrence had no changes in LA functional parameters during follow-up. The amount of LA LGE at long-term follow-up was higher compared to the baseline, however, was significantly less compared to immediately post-procedure (37 ± 1.9% vs. 47 ± 2.8%; p = .015). A higher increase in LA LGE extent compared to the baseline was associated with a greater decrease in total LAEF (r = -.59; p < .001).

LA function is impaired acutely following AF catheter ablation. However, long-term changes of LA function are associated positively with the successful restoration of sinus rhythm and inversely with increased LA LGE.

LA function is impaired acutely following AF catheter ablation. However, long-term changes of LA function are associated positively with the successful restoration of sinus rhythm and inversely with increased LA LGE.Among 626 participants of the Men's Lifestyle Validation Study (2011-2013), we evaluated the validity and reproducibility of a self-administered 152-item semiquantitative food frequency questionnaire (SFFQ) using two 7-day dietary records (7DDRs), four automated self-administered 24-hour dietary recalls (ASA24s), four 24-hour urine samples, one doubly-labeled water measurement (repeated in 104 participants), and two fasting blood samples, collected over 15 months. Compared to 7DDRs, SFFQs underestimated energy intake, macronutrients, and sodium intake, but overestimated some micronutrients. The mean of Spearman correlation coefficients was 0.66 (range 0.38 to 0.88) between 46 energy-adjusted nutrients estimated from 7DDRs and the final SFFQ, de-attenuated for within-person variation in the 7DDRs. These deattenuated correlations were similar using ASA24s as the comparison. Relative to biomarkers, SFFQs underestimated energy, sodium, and protein intakes, and the sodiumpotassium ratio. The energy-adjusted correlations between the final SFFQ and the biomarkers were slightly lower than the correlations between the SFFQ and 7DDRs.
