Leadership issues in shadow education are under-researched in national, regional and international contexts. In China, local and central governments have imposed stringent control on academic K9 paid tutorial lessons, provided by cram schools under the new double reduction policy (DRP). Many large-scale cram schools have undergone drastic changes in their organizational structure, marketing strategies and the working environment under the COVID-19 attack and DRP. This study aims to conceptualize how their academic managers in some regions of China exhibited traits of entrepreneurial leadership involving competence and resilience. Qualitative research methods included content analysis of policy documents, observation of tutorial lessons and semi-structured interviews with academic managers. Without overgeneralization, this study merely acts as a motivational guide for complementing the existing research literature on cram schools in China and enriching the international research literature on entrepreneurial leadership in mass tutoring.

Public space is commonly concerned from its social and political dimension, without clear distinctions between space and the public sphere. In addition, debates about the public came from ideas that emerged in the global north. The present document argue that it is necessary to restore the spatial condition of the public as well as its formal dimension to discuss why and whom the public is built in the south. An analysis of the elements of the typological urban form of emblematic towns in Santiago de Chile as a represented space, also known as 9x18 neighborhoods, is proposed. Four design hypotheses about neighborhoods are discussed, based on their land distribution, the hierarchies of their space, the bonds between neighbors and their relations with government services. It is concluded that the public space of the Chilean "poblaciones" built in the 1960s was intended by urban policy as a space that related the inhabitants with the State services.

Introduction: The incidence of risk factors such as high blood pressure, diabetes mellitus, dyslipidemia, obesity and tobacco smoking in increasingly aging populations have contributed to the high incidence of acute coronary syndrome. Objective: To determine the relationship of risk factors and cardiovascular complications with the form of presentation of acute coronary syndrome. Method: Descriptive cross-sectional study with analytical component was carried out. All patients with diagnosis of acute coronary syndrome, admitted to the Coronary Intensive Care Unit of the Hospital Universitario Manuel Fajardo of Havana, Cuba, were enrolled, between 2016 and 2020. Results: The risk factors with greater frequency were: ischemic heart disease (51%), high blood pressure (81.3%), diabetes mellitus (29.3%) and tobacco smoking (57.2%). Approximately 19.4% of patients presented some type of cardiovascular complication. A significant association between a history of ischemic heart disease (p<0.001), high blood pressure (p<0.001), diabetes mellitus (p=0.034), dyslipidemia (p=0.023), and the presence of ST-segment elevation acute coronary syndrome was found. Conclusions: A history of ischemic heart disease, high blood pressure, diabetes mellitus, dyslipidemia and cardiovascular complications were associated with non-ST-segment elevation acute coronary syndrome, while smoking habit was associated with ST-segment elevation acute coronary syndrome.

This study describes nursing experiences in caring for a patient who are newly diagnosed with advanced lung adenocarcinoma. The study covers the nursing period from July 2 to July 17, 2018, and adopted the Gordon 11 Health Functions for overall evaluation analysis to determine the health problems of gas exchange disorder, uncertainty, and coping ability of the family. Based on a interdisciplinary teamwork among social workers, the case manager, and physicians, the care and guidance of lung rehabilitation exercises and target therapy were provided in order to strengthen the coping ability of patients and their families when facing the disease and therapy, guide, coordinate, and communicate during the repair of family relations, and reduce the inner sense of uncertainty with the assistance of wardmate support groups. Findings herein can be a reference for colleagues when caring for similar cases in the future. [ABSTRACT FROM AUTHOR]

In the context of the current COVID-19 epidemic, numerous are the manifestations of the infected patients, including the alterations in the 12-lead electrocardiogram, where the presence of a J-wave can be found, secondary to the generation of a transmural voltage gradient, caused by the overexpression of the channels for transient outward potassium current (Ito), in the context of a severe infection with extensive myocardial injury. In this article is presented the case of an 83-year-old patient with a positive diagnosis of COVID-19, who progressed to septic shock, with mixed acidosis and mild hyperkalemia. The electrocardiogram showed the presence of a Jwave, probably secondary to the effect of pro-inflammatory cytokines on potassium channels and extensive areas of myocardial injury.

Introduction: a varicocele is the abnormal dilatation of the pampiniform plexus, incidence varies according to age between 4 and 15% Objective: compare the results of varicocele treatment using open vs laparoscopic technique in children and teenagers. Methods: this study was performed in the Dr. Roberto Gilbert Elizalde Children's Hospital in Guayaquil (Ecuador) from January 2015 to December 2020. It is a retrospective, descriptive, cross sectional study. Patients included were between 0 and 18 years old, had a diagnosis of varicocele, and open (Subinguinal) or laparoscopic technique (Palomo) had been performed. Results: 70 patients were included, in all of them the left side was affected. The mean age was 13.93 years. 61 (87%) patients had stage III varicocele and the remaining 9, stage II. Laparoscopic technique was used in 36 (51%) patients and open surgery technique in 34 (49%). The average duration for laparoscopic technique was 58.89 min, for open surgery technique it was 53.38 min. All patients were discharged the same day of surgery. In the laparoscopic technique group 2 (5.6%) developed a hydrocele. 1(2.8%) had a varicocele relapse. In the open surgery technique group 1 (2.9%) patient developed hydrocele. Conclusion: this is the first study in Ecuador comparing open vs laparoscopic technique as treatment options for varicocele. Both of these options show a good outcome, nonetheless, the decision to use either technique depends on the surgeons experience and the availability of the necessary technological tools found in each hospital.

COVID-19 is a serious respiratory disease. The ever-increasing number of cases is causing heavier loads on the health service system. Using 38 blood test indicators on the first day of admission for the 422 patients diagnosed with COVID-19 (from January 2020 to June 2021) to construct different machine learning (ML) models to classify patients into either mild or severe cases of COVID-19. All models show good performance in the classification between COVID-19 patients into mild and severe disease. The area under the curve (AUC) of the random forest model is 0.89, the AUC of the naive Bayes model is 0.90, the AUC of the support vector machine model is 0.86, and the AUC of the KNN model is 0.78, the AUC of the Logistic regression model is 0.84, and the AUC of the artificial neural network model is 0.87, among which the naive Bayes model has the best performance. Different ML models can classify patients into mild and severe cases based on 38 blood test indicators taken on the first day of admission for patients diagnosed with COVID-19.

Genomic surveillance of severe acute respiratory syndrome coronavirus 2 (SARSCoV- 2) plays an important role in COVID-19 pandemic control and elimination efforts, especially by elucidating its global transmission network and illustrating its viral evolution. The deployment of multiplex PCR assays that target SARS-CoV-2 followed by either massively parallel or nanopore sequencing is a widely-used strategy to obtain genome sequences from primary samples. However, multiplex PCR-based sequencing carries an inherent bias of sequencing depth among different amplicons, which may cause uneven coverage. Here we developed a two-pool, long-amplicon 36-plex PCR primer panel with ~1000-bp amplicon lengths for full-genome sequencing of SARS-CoV-2. We validated the panel by assessing nasopharyngeal swab samples with a <30 quantitative reverse transcription PCR cycle threshold value and found that =90% of viral genomes could be covered with high sequencing depths (=20% mean depth). In comparison, the widely-used ARTIC panel yielded 79%-88% high-depth genome regions. We estimated that ~5 Mbp nanopore sequencing data may ensure a >95% viral genome coverage with a =10-fold depth and may generate reliable genomes at consensus sequence levels. Nanopore sequencing yielded falsepositive variations with frequencies of supporting reads <0.8, and the sequencing errors mostly occurred on the 5' or 3' ends of reads. Thus, nanopore sequencing could not elucidate intra-host viral diversity. [ABSTRACT FROM AUTHOR]

Recently, the coronavirus disease 2019 (COVID-19) has caused a global pandemic. Several studies indicate that the digestive system can also be affected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Therefore, patients with digestive symptoms should have a capsule endoscopy (CE). COVID-19 patients with gastrointestinal (GI) symptoms who underwent CE were recruited from March 2020 to April 2020. We collected patients' data and performed a prospective follow-up study for 6 months. All 11 COVID-19 cases with GI symptoms who underwent CE presented gastritis. Eight cases (72.7%) had intestinal mucosa inflammation. Among them, two cases showed intestinal ulcers or erosions. Moreover, two cases displayed colonic mucositis. One case was lost during follow-up. At 3-6 months after hospital discharge, five patients underwent CE again, presenting gastrointestinal lesions. Five of the 10 cases had GI symptoms, such as abdominal pain, diarrhea, constipation, and others. Among these five cases, the GI symptoms of three patients disappeared at the last follow-up and two patients still presented diarrhea symptoms. Overall, we observed damaged digestive tract mucosa that could be caused by SARS-CoV-2. Moreover, after discharge, some patients still presented intestinal lesions and GI symptoms.

In this study, we investigate the mediating effects of children's Internet use on the relationship between family socioeconomic status and their academic achievement, and whether the mediating effects vary across different academic subjects. We used the data from the China Family Panel Studies on the socioeconomic status of children's families, children's Internet use, and their academic performance. In the 2014 sample, there were 2,686 participants (females=1,272). In 2016, there were 2,330 participants (females=1,069), and in 2018, there were 2,485 participants (females=1,151). The socioeconomic status and the Internet use were measured by a questionnaire. Standardized tests measured the academic performance. Our findings showed that family socioeconomic status was positively related to math performance, but not significantly related to Chinese performance. The results also indicated that Internet use did not significantly mediate the relationship between family socioeconomic status in 2014 and math performance in 2016, while the frequency of Internet use to study in 2016 partly mediated the relationship between family socioeconomic status in 2016 and math performance in 2018. Our findings suggest that Internet use can only mediate the relationship between family socioeconomic status and math performance and the mediating effects become stronger over time.

The COVID-19 pandemic has hit humanity without precedent since the beginning of 2020 and paralyzes the regular functioning of the world. However, some East Asian countries, especially China, which was the first epicenter of this pandemic, managed to combat the virus and quickly recovered from this health crisis. The data on infections from China, Japan, South Korea and Vietnam contrast tremendously with those obtained from Western countries. This paper analyzes the possible factors that explain the successful management of the pandemic in these countries. It turns out that beyond the radical restrictions of pandemic control, their experiences with contagious diseases and their cultures in which collectivism prevails constitute the innate advantages of these Asian countries, those that Western countries do not have and that facilitate the faster and more effective containment of coronavirus.

Purpose: The external physical vibration lithecbole (EPVL) is a new device that accelerates the discharge of urinary stones by changing the patient's body position and providing multi-directional simple harmonic waves. It is clinically employed to improve the stone-free rate (SFR). However, it is not widely accepted in clinical practice due to the lack of high-level evidentiary support and a standard protocol. The present meta-analysis aims at the evaluation of the efficacy and safety of EPVL treatment in improving the SFR. Methods: This study was a systematic review and meta-analysis. A systematic literature review was conducted using PubMed, Scopus, Embase, Medline, the Web of Science, and the Cochrane Library to find randomized controlled trials (RCTs) as recent as April 2020 that evaluated the efficacy and safety of EPVL treatment for patients with stones/residual stones in the upper urinary tract. Results: In total, 7 prospective studies with 1414 patients were included. Compared with patients in the control group, patients treated with an EPVL (the intervention group) had higher SFRs (95% CI: 0.59-0.86, RR = 0.71, P = .0004) and lower complication rates (95% CI: 1.37-3.12, RR = 2.07, P = .0006). In a subgroup analysis based on previous surgery (ESWL, RIRS), the intervention group had an improved SFR as compared to the control group (95% CI: 0.59-0.95, RR = 0.75, P = .02; 95% CI: 0.56-0.73, RR = 0.64, P < .00001, respectively). In a subgroup analysis based on stone location, the SFRs for stones in the upper/middle/lower calyx and renal pelvis were significantly higher in the intervention group than in the control group: for residual stones in the upper and middle calyx, 95% CI: 0.63-0.98, RR = 0.79, and P = .03; for residual stones in the lower calyx, 95% CI: 0.54-0.75, RR = 0.64, and P < .00001; for residual stones in the renal pelvis, 95% CI: 0.47-0.79, RR = 0.61, and P = .0002. However, the SFRs for ureter stones were not significantly different between groups (95% CI: 0.82 -1.05, RR = 0.93, P = .23). Conclusion: The external physical vibration lithecbole can effectively improve the SFR after ESWL and RIRS without significant side effects, especially for residual stones in the upper/middle/lower calyx and renal pelvis.

Purpose: To investigate the specific role of melanotransferrin antisense RNA (MFI2-AS1) in esophageal cancer (EC) progression. Methods: The differential expression of MFI2-AS1 in EC tissues and cells was determined using quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Silencing MFI2-AS1 was performed by transfection with specific short hairpin RNAs targeting MFI2-AS1. The 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay (MTT) and flow cytometry (FC) were used to assess cell viability and apoptosis of EC cells, respectively. The sponging microRNA (miRNA) of MFI2-AS1 was validated using luciferase activity and RNA immunoprecipitation assays while the downstream target gene of the sponging miRNA was evaluated by luciferase activity assay. Results: MFI2-AS1 was significantly enhanced in EC tissues (p < 0.01) and indicated a poor prognosis in EC patients. Knockdown of MFI2-AS1 in EC cells decreased cell viability and promoted cell apoptosis of EC cells. Functionally, MFI2-AS1 targeted miR-331-3p, and sex-determining region on Ychromosome- related high-mobility-group box4 (SOX4) was identified as a target gene of miR-331-3p. Ectopic expression of SOX4 counteracted the suppressive effect of MFI2-AS1 knockdown on EC cell viability and stimulative effect on EC cell apoptosis. Conclusion: The pro-oncogenic effect of MFI2-AS1 on EC progression occurs via the regulation of the miR-331-3p/SOX4 axis, providing a new potential therapeutic target for EC. [ABSTRACT FROM AUTHOR]
