Abstract
We aimed to compare the short- and long-term outcomes between robotic esophagectomy (RE) and open esophagectomy (OE) in patients with esophageal squamous cell carcinoma (ESCC). Among the patients who underwent esophagectomy for ESCC from 2008 to 2017, 402 patients (n = 178 in RE and n = 224 in OE) were enrolled and, after propensity-score matching, 136 patients in each group were selected. The total rate of complications was comparable, whereas the rate of major complications was higher in OE (p < 0.01). Hospital stay was longer in OE (15 days in OE vs. 13 days in RE; p = 0.03) with a comparable early mortality rate. Complete resection was equally achieved in both groups (96.3% in RE vs. 97.0% in OE; p = 0.74). The numbers of retrieved lymph nodes (LN) were significantly higher in RE (42.8 in RE vs 35.3 in OE; p < 0.01), especially for LNs in the left lower cervical paratracheal, both recurrent laryngeal nerves, and paraesophageal area. The 5-year overall survival rate was higher in RE (75.1% in RE vs. 57.9% in OE; p = 0.02), whereas, the freedom from recurrence was comparable between the two groups (68.8% in RE vs. 54.7% in OE; p = 0.15). Notably, RE achieved a significantly higher rate of 5-year freedom from regional nodal recurrence than OE (81.4% in RE vs. 62.7% in OE, p = 0.03). RE contributed to a lower rate of major complications and shorter hospital stays. Furthermore, RE showed increased long-term overall survival and freedom from regional LN recurrence rates, with a higher yield of LN dissection compared to OE.

Abstract
BACKGROUND Particulate matter (PM) is a mixture of solid and liquid particles suspended in air, which originates from industrial plants or vehicle emissions. Although the skin is the primary body area of contact with air pollutants, the associations between PM and chronic inflammatory skin diseases has not been well established. AIM To investigate associations between PM and atopic dermatitis (AD) and between PM and other chronic inflammatory dermatoses, using data from the Korean Health Insurance Review and Assessment Service. METHODS Monthly disease statistics from the seven largest cities in South Korea (Seoul, Busan, Daegu, Incheon, Gwangju, Daejeon, Ulsan) and from Jeju Island (in total, a population of 23 288 000 for all eight areas) were included. Based on daily air pollution level and weather forecast from 2015 to 2019, multivariate negative binomial regression analysis was conducted to estimate monthly visits of AD with respect to outdoor air pollutants: coarse PM with a diameter of ≤ 10 μm (PM10) and fine PM with a diameter of ≤ 2.5 μm (PM2.5) ozone (O3 ), nitrogen dioxide (NO2 ), sulphur dioxide (SO2 ) and carbon monoxide (CO). RESULTS Increases in the levels of PM2.5, PM10, SO2 and CO were associated with significant increases in monthly patient visits for AD. Every 10 μg/m3 increase in PM2.5 and PM10 resulted in patient visit increases of 2.71% (95% CI 0.76-4.71; P < 0.01) and 2.01% (95% CI 0.92-3.11, P < 0.001), respectively, while every 1 part per billion (ppb) increase in SO2 and every 100 ppb increase in CO resulted in visit increases of 2.26% (95% CI 1.35-3.17; P < 0.001) and 2.86% (95% CI 1.35-4.40; P < 0.001), respectively. O3 and NO2 were not associated with increased patient visits for AD. Increases in PM2.5 and PM10 concentrations were also significantly associated with increases in patient visits for psoriasis, seborrhoeic dermatitis and rosacea. CONCLUSION Our data suggest that PM is associated with AD and other chronic inflammatory skin diseases.

Abstract
OBJECTIVES Surgical resection is the best option for the treatment of early-stage lung cancer. However, older patients are less likely to receive curative treatment. Therefore, we compared long-term survival rates between surgical resection and stereotactic ablative radiotherapy (SABR) for the treatment of early-stage lung cancer in older patients. METHODS From 2013 to 2016, 272 patients aged ≥75 years with clinical stage I lung cancer underwent surgical resection (n = 191) or SABR (n = 81). A propensity score-matched analysis was performed. Overall survival, cumulative incidence of cancer-related death and recurrence were compared between the 2 groups. RESULTS In the matched cohort, 48 well-balanced pairs were extracted. An overall survival benefit was associated with surgery (surgery vs SABR = 65.9% vs 40.3%; P = 0.034); however, there was no significant difference in the cumulative incidence of cancer-related death (P = 0.089) or recurrence (P = 0.111) between the 2 groups. Systemic dissemination was the dominant pattern of progression in both groups. The 3-year cumulative incidence of regional recurrence was significantly higher in the SABR group compared to the surgery group (surgery vs SABR = 0% vs 11.4%, P = 0.046). CONCLUSIONS Surgical resection with mediastinal lymph node dissection provides better long-term survival compared to SABR in older patients with stage I lung cancer. Surgery should be considered for older patients aged ≥75 years who are appropriate candidates for surgery. SABR remains an alternative treatment with comparable cancer-related death and recurrence for patients unsuitable for surgery.

Abstract
OBJECTIVES The association between adjuvant chemotherapy (AC) and chronic postoperative pain (CPP) after video-assisted thoracoscopic surgery (VATS) for lung cancer resection has not yet been reported. We, therefore, investigated the association between AC and the long-term incidence of CPP after VATS. METHODS We retrospectively reviewed 3015 consecutive patients who underwent VATS for lung cancer between 2007 and 2016. The patients were divided into 2 groups: those who received (AC group) and those who did not receive (non-AC group) AC within 3 months after VATS. Propensity score analysis was performed to adjust for baseline differences between the 2 groups. The cumulative incidence of CPP at the intervals of 3 months, over 36 months, was compared before and after matching. A Cox proportional hazards regression analysis was used to investigate the predictors of CPP after VATS. RESULTS We included and assessed 2222 patients in this study. Of these, 320 patients (14.4%) received AC within 3 months post-VATS. The cumulative incidence of CPP during 36 months post-surgery was significantly higher in the AC group than in the non-AC group, before and after matching (log-rank test; P = 0.002 and 0.027, respectively). Cox proportional hazards regression analysis also showed that AC was a significant risk factor for CPP (hazard ratio 1.62, 95% confidence interval 1.16-2.28; P = 0.005). CONCLUSIONS Our results indicate that AC is an important risk factor for CPP after VATS. Further understanding of the risk factors for CPP may facilitate its prediction and treatment.

Abstract
We have built a wireless implantable microelectronic device for transmitting cortical signals transcutaneously. The device is aimed at interfacing a microelectrode array cortical to an external computer for neural control applications. Our implantable microsystem enables presently 16-channel broadband neural recording in a nonhuman primate brain by converting these signals to a digital stream of infrared light pulses for transmission through the skin. The implantable unit employs a flexible polymer substrate onto which we have integrated ultra-low power amplification with analog multiplexing, an analog-to-digital converter, a low power digital controller chip, and infrared telemetry. The scalable 16-channel microsystem can employ any of several modalities of power supply, including via radio frequency by induction, or infrared light via a photovoltaic converter. As of today, the implant has been tested as a sub-chronic unit in non-human primates (~ 1 month), yielding robust spike and broadband neural data on all available channels.

Abstract
BACKGROUND Electromagnetic navigation bronchoscopy (ENB)-guided dye marking is a useful localization modality for small pulmonary nodules. The purpose of this study was to evaluate the efficacy and safety of intraoperative full virtual ENB-guided dye marking. METHODS Patients who underwent full virtual ENB-guided dye marking without adjunct intraoperative imaging (fluoroscopy or cone beam computed tomography) for small pulmonary nodules were investigated retrospectively. Efficacy was evaluated on the basis of the success rates of dye marking (visible dye mark) and nodule localization, and safety was evaluated on the basis of the rate of ENB-related complications. RESULTS ENB-guided dye marking was performed on 164 nodules in 134 patients. Twenty-seven (20.1%) patients had multiple nodules. The total number of dye-marking attempts was 241, and the mean number of markings per nodule was 1.5±0.7. The mean ENB procedure duration was 30±15.1 min. No ENB-related complications were observed. The success rate of dye marking was 86.7% (209/241), and that of localization was 94.5% (155/164). Among 63 nodules with multiple dye-marking attempts, 62 (98.4%) were successfully localized. In 101 nodules with a single dye-marking attempt, 88 (87.1%) were localized with the visceral pleural dye mark. Additionally, 6 (5.9%) nodules could be localized with the needle hole on the visceral pleura. The number of dye-marking attempts was a significant factor in the success of localization (1.5±0.7 versus 1.1±0.3, p=0.01). CONCLUSIONS Full virtual ENB-guided dye marking was effective and safe for the localization of small pulmonary nodules. A multiple dye-marking strategy is recommended to achieve a high success rate.

Abstract
OBJECTIVES Robotic thymectomy via the subxiphoid approach (RTX) is a recently introduced surgical approach. This study aimed to report on the surgical technique and early outcomes of RTX in our institute. METHODS RTX was performed using the 3-arm technique in the da Vinci robotic surgical system. The camera was inserted into a subxiphoid port, and 2 robotic arms were inserted in bilateral intercostal ports. A complete dissection of both cervical poles up to the thyroid gland was conducted, and bilateral phrenic nerves were identified in all cases. Radical combined resection of adjacent organs, including the lung, pericardium, phrenic nerve and the innominate vein, was performed if necessary. The resected specimen could be retrieved through the subxiphoid port site. RESULTS A total of 110 patients underwent RTX in our institute from October 2016 to August 2019. Thymoma was the most common diagnosis (60.9%), and the mean size of the tumours was 4.9 ± 2.4 cm. Combined resection was performed in the lung (n = 9, 8.1%), pericardium (n = 6, 5.5%) and innominate vein (n = 5, 4.5%). There were 2 minor postoperative complications (1.8%), and the mean length of hospital stay was 2.2 ± 1.4 days. For the cumulative sum curve analysis of the learning curve using operative time, 50 cases were necessary to gain proficiency. CONCLUSIONS RTX was a safe and feasible surgical approach, even in advanced thymic epithelial tumours. It should be considered one of the valuable surgical options in minimally invasive thymectomy.

Abstract
We have developed an advanced process for blaze angle reduction of x-ray gratings for the soft, tender, and EUV spectral ranges. The process is based on planarization of an anisotropically etched Si blazed grating followed by a chemically selective plasma etch. This provides a way to adjust the blaze angle to any lower value with high accuracy. Here we demonstrate the reduction of the blaze angle to an extremely low value of 0.04°±0.004°. For a 100 lines/mm grating with a Mo/Si multilayer coating, the grating exhibits diffraction efficiency of 58% in the 1st diffraction order at a wavelength of 13.3 nm. This technique will be applicable to a wide range of uses of high efficiency gratings for synchrotron sources, as well as for Free Electron Lasers (FEL).

Abstract
We report a precision measurement of the parity-violating asymmetry A_{PV} in the elastic scattering of longitudinally polarized electrons from ^{208}Pb. We measure A_{PV}=550±16(stat)±8(syst) parts per billion, leading to an extraction of the neutral weak form factor F_{W}(Q^{2}=0.00616 GeV^{2})=0.368±0.013. Combined with our previous measurement, the extracted neutron skin thickness is R_{n}-R_{p}=0.283±0.071 fm. The result also yields the first significant direct measurement of the interior weak density of ^{208}Pb: ρ_{W}^{0}=-0.0796±0.0036(exp)±0.0013(theo) fm^{-3} leading to the interior baryon density ρ_{b}^{0}=0.1480±0.0036(exp)±0.0013(theo) fm^{-3}. The measurement accurately constrains the density dependence of the symmetry energy of nuclear matter near saturation density, with implications for the size and composition of neutron stars.

BACKGROUND: Pyrazinamide (PZA) is an important anti-tuberculosis drug for multidrug-resistant tuberculosis (MDR-TB). However, PZA has recently been demoted within the hierarchy of TB drugs used for MDR-TB.METHODS: We conducted a retrospective cohort study to investigate treatment outcomes for simple MDR-TB (susceptible to both second-line injectable drugs and fluoroquinolones) according to PZA susceptibility.RESULTS: Among 216 pulmonary MDR-TB patients included in the study, 68 (31.5%) were PZA-resistant (PZA-R). The mean age was 41.8 years, and 63.4% were male. Baseline characteristics such as comorbidity, previous TB history, acid-fast bacilli (AFB) smear positivity and cavitation were similar in PZA-susceptible (PZA-S) and PZA-R patients. The number of potentially effective drugs was slightly higher among PZA-S patients than among the PZA-R (5.1 vs. 4.8, respectively; P = 0.003). PZA was more frequently used in PZA-S patients (73.0%) than in the PZA-R (14.7%), while para-aminosalicylic acid was more frequently used in PZA-R than in PZA-S patients (76.5% vs. 50.7%). The treatment success rate was similar in PZA-S (77.7%) and PZA-R (75.0%) patients. PZA resistance was not associated with treatment success in multivariate analysis.CONCLUSIONS: PZA-resistant simple MDR-TB patients had the same treatment success rate as the PZA-susceptible group even without using novel anti-TB drugs.

Abstract
We present the first results of the Fermilab National Accelerator Laboratory (FNAL) Muon g-2 Experiment for the positive muon magnetic anomaly a_{μ}≡(g_{μ}-2)/2. The anomaly is determined from the precision measurements of two angular frequencies. Intensity variation of high-energy positrons from muon decays directly encodes the difference frequency ω_{a} between the spin-precession and cyclotron frequencies for polarized muons in a magnetic storage ring. The storage ring magnetic field is measured using nuclear magnetic resonance probes calibrated in terms of the equivalent proton spin precession frequency ω[over ˜]_{p}^{'} in a spherical water sample at 34.7 °C. The ratio ω_{a}/ω[over ˜]_{p}^{'}, together with known fundamental constants, determines a_{μ}(FNAL)=116 592 040(54)×10^{-11} (0.46 ppm). The result is 3.3 standard deviations greater than the standard model prediction and is in excellent agreement with the previous Brookhaven National Laboratory (BNL) E821 measurement. After combination with previous measurements of both μ^{+} and μ^{-}, the new experimental average of a_{μ}(Exp)=116 592 061(41)×10^{-11} (0.35 ppm) increases the tension between experiment and theory to 4.2 standard deviations.
