Authors: Guo Juan , Hu Qingwei , Deng Zaixing , Jin Xiaotian 
Published: November 2021

Objective: To provide updated evidence on comparative efficacy for clinical outcomes of radical trachelectomy and radical hysterectomy in patients with early-stage cervical cancer.Methods: A systematic search was conducted in the PubMed, Scopus, Cochrane Database of Systematic Reviews, and Google scholar databases. Studies were done in patients with early-stage cervical cancer that compared the outcomes between radical trachelectomy (RT) and hysterectomy (RH) were considered for inclusion in the review. The outcomes of interest were operative time, the volume of blood loss, need for blood transfusion, any complications, length of hospital stay, risk of recurrence, and survival. The strength of association was presented in the form of pooled relative risk (RR), hazards risk (HR), and weighted mean difference (WMD). Statistical analysis was done using STATA version 16.0.Results: A total of 12 articles were included in the meta-analysis. The majority were retrospective cohort-based studies. Compared to RH, the operative time (in min) was comparatively higher in RT (WMD 23.43, 95% CI: 5.63, 41.24). Patients undergoing RT had blood loss (in ml) similar to those undergoing RT (WMD −81.34, 95% CI: −170.36, 7.68). There were no significant differences in the risk of intra-operative (RR 1.61, 95% CI: 0.49, 5.28) and post-operative complications (RR 1.13, 95% CI: 0.54, 2.40) between the two groups. Patients in the RT group had lesser duration of post-operative hospital stay (in days) (WMD −1.65, 95% CI: −3.22, −0.09). There was no statistically significant difference in the risk of recurrence (HR 1.21, 95% CI: 0.68, 2.18), 5-year overall survival (HR 1.00, 95% CI: 0.99, 1.02), and recurrence-free survival (HR 0.99, 95% CI: 0.96, 1.01) between the two groups.Conclusion: Among the patients with early-stage cervical cancer, RT is similar to RH in safety and clinical outcomes. Future studies with a randomized design and larger sample sizes are needed to further substantiate these findings.

Objectives: Providing medical care during a global pandemic exposes healthcare workers (HCW) to a high level of risk, causing anxiety and stress. This study aimed to assess the prevalence of anxiety and psychological distress among HCWs during COVID-19.Methods: We invited HCWs from 3 hospitals across the United Arab Emirates (UAE) to participate in an anonymous online survey between April 19–May 3, 2020. The GAD-7 and K10 measures were used to assess anxiety and psychological distress. Logistic regression models assessed associations between knowledge, attitude, worry, and levels of anxiety and psychological distress.Results: A total of 481 HCWs participated in this study. The majority of HCWs were female (73.6%) and aged 25–34 years (52.6%). More than half were nurses (55.7%) and had good knowledge of COVID-19 (86.3%). Over a third (37%) of HCWs reported moderate/severe psychological distress in the K10 measure and moderate/severe anxiety (32.3%) in the GAD-7, with frontline workers significantly reporting higher levels of anxiety (36%). Knowledge of COVID-19 did not predict anxiety and psychological distress, however, HCWs who believed COVID-19 was difficult to treat and those who perceived they were at high risk of infection had worse mental health outcomes. Worry about spreading COVID-19 to family, being isolated, contracting COVID-19 and feeling stigmatized had 1.8- to 2.5-fold increased odds of symptoms of mental health problems. Additionally, HCWs who felt the need for psychological support through their workplace showed increased odds of psychological distress.Conclusion: HCWs in the UAE reported a high prevalence of psychological distress and anxiety while responding to the challenges of COVID-19. The findings from this study emphasize the public, emotional and mental health burden of COVID-19 and highlight the importance for health systems to implement, monitor, and update preventive policies to protect HCWs from contracting the virus while also providing psychological support in the workplace.

Tingkat Pengangguran Terbuka mengalami peningkatan di era pandemi Covid-19. Studi ini bertujuan untuk menganalisis sejauh mana pengaruh human capital (pendidikan dan pelatihan) terhadap durasi menganggur pada pekerja yang terkena PHK akibat pandemi Covid-19 di Indonesia. Studi ini diharapkan dapat memberikan gambaran terkait pentingnya human capital dalam mengurangi pengangguran di Indonesia akibat pandemi Covid-19. Hasil estimasi menggunakan regresi Cox menunjukkan bahwa semakin tinggi tingkat pendidikan pekerja yang terkena PHK akibat pandemi Covid-19 maka semakin lambat keluar dari pengangguran. Sedangkan, pekerja yang pernah terkena PHK akibat pandemi Covid-19 yang pernah mengikuti pelatihan bersertifikat memiliki risiko keluar dari pengangguran yang lebih cepat dibandingkan tidak pernah mengikuti pelatihan bersertifikat. Berdasarkan hasil penelitian dapat disimpulkan bahwa investasi human capital berupa pelatihan dapat mempercepat durasi menganggur pada pekerja yang terkena PHK akibat pandemi Covid-19 di Indonesia, sedangkan semakin tinggi investasi pada pendidikan justru memperlambat durasi menganggur.

Demonstration of toroidal metasurfaces through near-field coupling of bright-mode resonators
Authors: Mallick Soumyajyoti , Chourasia Nitin , Singh Rakesh , Roy Chowdhury Dibakar 
Published: November 2021

Abstract
Bright-mode resonances are not well-acknowledged for inducing mode hybridizations. However, we demonstrate that multiple bright resonators coupled through electromagnetic fields can induce resonance mode hybridizations. Although one of the hybridized modes shows parallel magnetic moments, the other demonstrates anti-parallel magnetic moments leading to magnetic toroidal resonances. The excitation of toroidal modes usually demands complex structures and/or bright–dark-mode interactions. However, in this study, we employ only bright resonators to excite toroidal modes. Unlike bright–dark-mode coupling, exclusive bright-mode resonance coupling enables larger free-space energy to merge into the metasystem, which leads to stronger energy confinement in the metasurface array.

Merging Criteria for Planetesimal Collisions

Published: November 2021

Abstract
In the standard scenario of planet formation, terrestrial planets, ice giants, and cores of gas giants are formed by the accumulation of planetesimals. However, there are few N-body simulation studies of planetesimal accretion that correctly take into account the merging condition of planetesimals. In order to investigate a realistic accretion process of planetesimals, it is necessary to clarify the merging criteria of planetesimals at collision. We perform numerical collision experiments using smoothed particle hydrodynamics and obtain the merging criteria as a function of planetesimal mass and impact parameters for undifferentiated rocky and icy planetesimals and differentiated icy planetesimals. We vary the total mass of colliding planetesimals, their mass ratios, and the impact angle and obtain the critical impact velocity as the merging criteria distinguishing merging from hit-and-run collision. We find that the critical impact velocity normalized by the two-body surface escape velocity decreases with increasing impact angle. The critical impact velocity does not depend on the total mass, while it has a weak positive dependence on the mass ratio. These results barely depend on the composition and internal structure of the planetesimals.
Split Invariant Curves in Rotating Bar Potentials
Authors: Xia Tian-Ye , Shen Juntai 
Published: November 2021

Abstract
Invariant curves are generally closed curves in Poincaré's surface of section. Here we study an interesting dynamical phenomenon, first discovered by Binney et al. in a rotating Kepler potential, where an invariant curve of the surface of section can split into two disconnected line segments under certain conditions, which is distinctively different from the islands of resonant orbits. We first demonstrate the existence of split invariant curves in the Freeman bar model, where all orbits can be described analytically. We find that the split phenomenon occurs when orbits are nearly tangent to the minor/major axis of the bar potential. Moreover, the split phenomenon seems “necessary” to avoid invariant curves intersecting with each other. Such a phenomenon appears only in rotating potentials, and we demonstrate its universal existence in other general rotating bar potentials. It also implies that actions are no longer proportional to the area bounded by an invariant curve if the split occurs, but they can still be computed by other means.
Uncovering Intense Ancient Solar Activity from Naked-eye Observations of Egg-like Sunspots
Authors: Wang Hongrui , Li Huiduan 
Published: November 2021

Abstract
Ancient sunspot records written in classical Chinese provide important information regarding ancient solar activity. The Chinese recorded 14 observations of sunspots that resembled an egg (hereafter, egg record; the word egg is used to represent approximate sunspot sizes) before 1000 CE. However, the egg records in classical Chinese were too short to provide sufficient sunspot details. This study was conducted to decode egg records from 1769 and 1917 through telescopic sunspot observations. The results of our decoding show that egg-like sunspots were generally used by observers in East Asia to represent a very large sunspot group with an approximately elliptical outline. An egg record generally served as a marker of intense solar activity. Three egg records (in 1278, 1769, and 1917) were observed to be close to the solar maxima, with the time difference being smaller than 1 yr. Some egg records could thus be used to identify the solar maxima. The mean time difference between 10 egg records and the nearest solar maxima is 2 yr. Therefore, egg records can provide necessary information for uncovering additional intense solar activity from ancient times.

Abstract
We report the discovery of a velocity coherent, kiloparsec-scale molecular structure toward the Galactic center region with an angular extent of 30° and an aspect ratio of 60:1. The kinematic distance of the CO structure ranges between 4.4 and 6.5 kpc. Analysis of the velocity data and comparison with the existing spiral arm models support that a major portion of this structure is either a subbranch of the Norma arm or an interarm giant molecular filament, likely to be a kiloparsec-scale feather (or spur) of the Milky Way, similar to those observed in nearby spiral galaxies. The filamentary cloud is at least 2.0 kpc in extent, considering the uncertainties in the kinematic distances, and it could be as long as 4 kpc. The vertical distribution of this highly elongated structure reveals a pattern similar to that of a sinusoidal wave. The exact mechanisms responsible for the origin of such a kiloparsec-scale filament and its wavy morphology remains unclear. The distinct wave-like shape and its peculiar orientation makes this cloud, named as the Gangotri wave, one of the largest and most intriguing structures identified in the Milky Way.

Introduction: The conventional interferon therapy of hepatitis C virus has been substituted substantially with sofosbuvir and daclatasvir due to constraints in efficacy and tolerability. This study aimed diagnostically to monitor the effectiveness and side effects of direct-acting antivirals in the management of HCV infections.
Methodology: This prospective study was conducted on HCV-infected patients treated with sofosbuvir and daclatasvir. Different serological, biochemical, hematological, and molecular techniques were used for the assessment of patients. Only treatment-naive patients aged ≥ 18 to 75 years received 12 weeks of treatment. The primary endpoint was a sustained virologic response with undetectable HCV RNA in the patients’ serum at the end of the treatment.
Results: We identified 229 cases of confirmed HCV infections by PCR, 94.3% of which had genotype 3. The study population comprised 66% females and 34% males with a median age of 42.2 ± 10.6 SD. Ninety-three percent of the patients accomplished SVR at week 12. The combined therapy of SOF/DAC achieved the highest efficacy rate (92.6%) among the different HCV genotype 3 patients. A statistically significant relationship was observed between low baseline viral load (p < 0.001; 95% CI = 1.2-3.1) and HCV genotype 3 with minor side effects, including lethargy, headache, nausea, insomnia, diarrhea, and fever.
Conclusions: HCV-infected patients can be treated well with an interferon-free SOF/DAC regimen, tolerated with generally mild adverse effects with a higher SVR.

Introduction: Tuberculosis remains a major health problem worldwide, killing thousand adults and children every year mainly in developing countries as Brazil. The disease is socially determined, caused mainly by inequalities as overcrowding, bad conditions of housing, unemployment, and limited access to health care. The aim of this study was to identify the social inequalities associated with the onset of tuberculosis in disease-prone territories in a city from the Northeast.
Methodology: This was an ecological study, which has gathered patients diagnosed with tuberculosis through secondary data source in a city from the northeast of Brazil. The GAMLSS statistical model has been applied considering as response variable the count of Tuberculosis cases and the independent variable, the social conditions. The double Poisson distribution was considered in the analysis. The best model fitted was selected according the Akaike information criterion value. For all tests, the p value < 0.05 was considered as statistically significant.
Results: 460 patients with diagnosis of tuberculosis were identified, which represents an incidence of 36.3 cases/100,000 in males and 20.7 cases/100,000 in females. Regarding social inequality associated with tuberculosis, income (households with per capita income between 1/8 and 3 minimum wages), gender and age (Proportion of males under 15 years of age) were associated with the disease.
Conclusions: The findings evidenced the social determinants associated with tuberculosis, with a greater occurrence of the disease in areas with mostly male children and low-income families, these issues must be managed within and beyond the health sector, which is mandatory for the Tuberculosis elimination.
