Significance Statement
Health care–associated infections during previous serious coronavirus epidemics resulted from human-to-human transmission in hemodialysis (HD) facilities. The authors analyzed the effect of a strategy of HD with cohort isolation on the secondary transmission of coronavirus disease 2019 (COVID-19) in HD facilities in Korea, which involves administering an immediate screening test for COVID-19 to all close contacts (patients on HD and health care workers) and strict maintenance of cohort isolation. Epidemiologic investigation and immediate screening tests across 11 HD centers identified 302 close contacts. HD with cohort isolation was maintained for a median of 14 days, and the transmission rate was 0.66% inside HD units. Clinical practice guidelines for HD with cohort isolation during COVID-19 outbreaks may successfully prevent secondary transmission through HD units.

Background
Health care–associated infections during previous coronavirus epidemics involving severe acute respiratory syndrome and Middle East respiratory syndrome resulted from human-to-human transmission in hemodialysis (HD) facilities. The effect of a strategy of HD with cohort isolation—separate dialysis sessions for close contacts of patients with confirmed coronavirus disease 2019 (COVID-19)—on the prevention of secondary transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in HD units is unknown.

Methods
Our multicenter cohort study of an HD with cohort isolation strategy enrolled close contacts of patients with confirmed COVID-19, including patients on HD and health care workers in HD units. Close contacts had been identified by epidemiologic investigation and tested negative on an immediate screening test for SARS-CoV-2.

Results
As of March 14, 11 patients on HD and 7 health care workers from 11 HD centers were diagnosed as having COVID-19. The immediate screening test was performed in 306 people, and among them, 302 close contacts with negative test results were enrolled. HD with cohort isolation was performed among all close contacts for a median of 14 days in seven centers. During cohort isolation, nine patients showed symptoms but tested negative for SARS-CoV-2. Two health care workers in the HD units (0.66% of the total group) were diagnosed at the termination test for SARS-CoV-2.

Conclusions
The transmission of COVID-19 can be controlled without closure of HD centers by implementing preemptive activities, including early detection with rapid testing, cohort isolation, collaboration between institutions, and continuous monitoring of infection. Our strategy and experience may provide helpful guidance for circumstances involving the rapid spread of infectious diseases such as COVID-19.

Buta The objectives of this study were to examine the effect of the autonomous learning process (ALP) on learner autonomy of undergraduate students in English public speaking class and its effect size; and to explore how learner autonomy is revealed through the ALP. This study employed a variant of a mixed-methods approach, which is an embedded experimental design. Employing the cluster sampling method, nineteen Thai students were included. The students were trained in the ALP based on the four dimensions of learner autonomy (technical, psychological, political-critical, and sociocultural.) Quantitative data were collected from the Learner Autonomy for Public Speaking (LAPS) questionnaires and analyzed by the dependent samples t-test. Qualitative data were drawn from the Overall Written Reflections, and thematic content analysis was used to analyze the data. The findings revealed that the level of students’ learner autonomy in the post-questionnaire significantly increased from the pre-questionnaire (p = 0.00). Its effect size is large (d = 1.28), and learner autonomy, as revealed through the ALP, can be classified into five emerging themes. The themes are (1) use and plans of the learning strategies, (2) evaluation of learning and learning strategies, (3) capacity to provide and accept praise and criticism, (4) increased positive emotions and (5) sense of awareness and a better understanding of self. Recommendations for further study are provided.The objectives of this study were to examine the effect of the autonomous learning process (ALP) on learner autonomy of undergraduate students in English public speaking class and its effect size; and to explore how learner autonomy is revealed through the ALP.

Seismicity, Stress State, and Style of Faulting of the Ridgecrest-Coso Region from the 1930s to 2019: Seismotectonics of an Evolving Plate Boundary Segment
Authors: Hauksson Egill , Jones Lucile M. 
Published: June 2020

ABSTRACTDecadal scale variations in the seismicity rate in the Ridgecrest-Coso region, part of the Eastern California Shear Zone, included seismic quiescence from the 1930s to the early 1980s, followed by increased seismicity until the 2019 Mw 6.4 and 7.1 Ridgecrest sequence. This sequence exhibited complex rupture on almost orthogonal faults and triggered aftershocks over an area of ∼90  km long by ∼5–10  km wide, which is a fraction of the area of the previously seismically active Indian Wells Valley and Coso range region. During the last 40 yr, the seismicity has been predominantly the result of strike-slip motion, extending north from the Garlock fault, along the Little Lake and Airport Lake fault zones, and approaching the southernmost Owens Valley fault to the north. The Coso range forms an extensional stepover between these two strike-slip fault systems. This evolution of a plate boundary zone is driven by the northwestward motion of the Sierra Nevada, and crustal extension along the southwestern edge of the Basin and Range Province. Stress inversion of focal mechanisms shows that the postseismic stress state consists of almost horizontal σ1 and vertical σ2. The σ1 is spatially rotated across the Coso range stepover with σ1-trending ∼N17° E to the north, whereas, along the Mw 7.1 mainshock rupture, the trend is ∼N6° E. The friction angles as measured between fault strikes and the σ1 trends correspond to a frictional coefficient of 0.75, suggesting average fault strength. In comparison, the mature Garlock fault has a smaller frictional coefficient of 0.28, similar to weak faults like the San Andreas fault. Thus, it appears that the heterogeneously oriented and spatially distributed but strong Ridgecrest-Coso faults accommodate seismicity at seemingly random places and times within the region and are in the process of self-organizing to form a major throughgoing plate-boundary segment.

Published: June 2020

El cultivo del cacao (Theobroma cacao L) ha adquirido gran importancia para Colombia en los últimos años, debido al incremento de las áreas cultivadas y al compromiso con su exportación por parte del Gobierno nacional. Para el año 2018, en el país había aproximadamente 170.000 hectáreas sembradas. Esta especie se cultiva entre los 20° de latitud norte y los 20° de latitud sur, a altitudes comprendidas entre los 0-1200 msnm. Los principales productores de cacao se encuentran ubicados en el continente africano (Ghana y Costa de Marfil), que contribuyen aproximadamente con el 70 % de la producción mundial. En América, la producción se enfoca en cultivos de cacao fino y de aroma, especialmente en países como Ecuador, Perú, Brasil, Colombia, México, entre otros. Los retos que enfrenta este cultivo en la actualidad son diversos: la escasa disponibilidad de mano de obra, la existencia de enfermedades limitantes como las causadas por Moniliophthora roreri y Phythophthora spp., y las restricciones establecidas por los
países consumidores frente a la presencia de ciertos metales pesados que son bioacumulados por el cacao y que pueden generar problemas a la salud humana. Por tanto, el objetivo de esta revisión es analizar las diferentes variables que intervienen en este cultivo, como instrumento de consulta para productores y técnicos interesados en este sistema productivo, con el fin de que se convierta en una herramienta en la toma de decisiones del cultivo y de sus implicaciones de establecimiento.

Geographic Variations and Trends in Primary and Revision Knee and Total Hip Arthroplasties in the United States
Authors: Hilibrand Ari S. , Rubin Lee E. , Grauer Jonathan N. 
Published: June 2020

Background:
Over 1 million joint arthroplasties are performed annually in the United States. Ideally, as devices and surgical techniques improve, the number of revision arthroplasties relative to primary arthroplasties should decrease. To our knowledge, this is the first study to evaluate state-by-state disparities in the ratio of revision to primary knee arthroplasty (unicompartmental and total) and total hip arthroplasty (THA).

Methods:
The National Inpatient Sample was used to identify patients who had undergone primary or revision knee arthroplasty or primary or revision THA from 2001 to 2011. Demographic characteristics, surgical rates, and revision ratios (the number of revision procedures divided by the number of primary procedures) were determined for the United States as a whole and by state.

Results:
During the study window, 47 states were sampled. For knee arthroplasty, 1,251,484 patients were identified: 91% underwent primary procedures and 9% underwent revision procedures. Compared with the primary knee arthroplasty cohort, the revision knee arthroplasty cohort had a younger mean age, had more male patients, and had more chronic conditions and longer hospitalizations (p < 0.001 for each). Over the years studied, the mean age of patients who had undergone primary knee arthroplasty decreased 1.8 years (p < 0.0001) and the mean age of those who had undergone revision knee arthroplasties decreased 2.4 years (p < 0.0001). The national revision ratio remained unchanged at around 0.1 (p = 0.8792). However, there was a 2.2-fold variation in revision ratio by state (revision ratio state range, 0.065 to 0.141). For THA, 614,638 patients were identified: 85% underwent primary procedures and 15% underwent revision procedures. Compared with the primary THA cohort, the revision THA cohort had an older mean age, had fewer male patients, and had more chronic conditions and longer hospitalizations (p < 0.001 for each). Over the years studied, the mean age of patients who had undergone primary THA decreased 1.5 years (p = 0.0016), whereas patients who had undergone revision had no significant age trend (p = 1.0000). Unlike for knee arthroplasty, the national THA revision ratio trended downward (0.24 evolved to 0.18, p = 0.0016), and there was a 2.1-fold variation in the revision ratio by state (revision ratio state range, 0.119 to 0.248).

Conclusions:
This study found significant variability in state-by-state revision ratios. It also found that the national revision ratio stayed relatively steady for knee arthroplasty but was decreasing for THA, and that patients who had undergone revision knee arthroplasty were getting younger, whereas patients who had undergone revision THA were not. These discrepancies suggest divergent histories for primary knee arthroplasty and THA and warrant further detailed evaluation.

Published: June 2020

Abstract
BACKGROUND : Gastric cancer (GC) is one of the most common malignant cancers, with high morbidity and mortality rates worldwide. The present study was to explore whether miR-200b is a tumor suppressor in GC and to unveil the potential mechanisms. METHODS: Levels of c-Myc, Cyclin D1, MMP-3 and MMP-9 expression were detected respectively by qRT-PCR and Western blot assay. BrdU proliferation assay, Cell cycle analysis, Wound-healing and Transwell assays were used to study the role of miR-200b with inhibitor, mimics or ZEB1-RNAi in TGF-β1-treated SGC-7901/DDP cells. RESULTS : Compared with the paracancerous tissues, miR-200b was decreased in GC patients and SGC-7901/DDP cells. Lower level of miR-200b induced by its inhibitor promoted TGF-β1-treated SGC-7901/DDP cells proliferation and migration, and increased the levels of c-Myc, Cyclin D1, MMP-3, MMP-9, β-catenin and APC. Interestingly, miR-200b mimics and ZEB1-RNAi were able to reduce the proliferation and migration of TGF-β1-induced SGC-7901/DDP cells as well as their levels of c-Myc, Cyclin D1, MMP-3 MMP-9, β-catenin and APC. In addition, ZEB1 was indeed the potential target of miR-200b identified by dual luciferase reporter gene assay. CONCLUSION : Taken together, our findings suggest that miR-200b be likely to play an important role in activating TGF-β1-induced SGC-7901/DDP cells and perform as a tumor suppressor by targeting ZEB1 in GC. What’s more, miR-200b may modulate Wnt/β-catenin signaling pathway in TGF-β1-induced SGC-7901/DDP cells.

Resilient care of the patient with COVID-19 in Iran: A phenomenological Study
Authors: Asgari Parvaneh , Jackson Alun C , Bahramnezhad Fatemeh 
Published: June 2020

Abstract
Background

Family caregivers understand several challenges in caring for patients with COVID-19.This study aimed to understand the experiences of Iranian family caregivers of persons with COVID-19.
Method:

This study utilized phenomenological hermeneutic design. Fourteen Iranian family caregivers of patients with COVID-19 who were quarantined at home were included in the study using purposive sampling. In-depth semi-structured interviews were conducted via WhatsApp. Sampling continued until data saturation. Interviews were transcribed and analyzed using Van Manen’s approach.
Result

Three primary themes and eight subthemes emerged. The primary themes included: ”captured in a whirlpool of time”, “resilient care’ and “feeling helpless”.
Conclusion

It seems that the families of patients with COVID-19 attempt to resist the pressures of this disease with religious practices and problem solving. However, due to the nature of the disease and its severity, they sometimes feel ashamed or lonely and are afraid of losing their loved ones. It is recommended that psychiatric nurses should develop programs in the form of comprehensive spiritual care packages or psychological support and utilize multiple media channels to deliver these.
