Nurses’ perceptions of factors influencing treatment engagement among patients with cardiovascular diseases: A systematic review
Authors: Rashidi Amineh , Whitehead Lisa , Kaistha Prachi 
Published: April 2021

Abstract
Background
Patient engagement in treatment plans is important in the management of cardiovascular disease. Nurses are key to the success of patient engagement, yet we know little about nurses’ perceptions on treatment engagement and how they can contribute to treatment engagement. Qualitative evidence to identify factors that influence treatment engagement among patients with CVD from nurse’s perspective is limited.
Methods
This systematic review of qualitative research was based on the PRISMA reporting guidelines. The Joanna Briggs Institute (JBI) Critical Appraisal Checklist was used to assess quality by two reviewers independently. Data were collected from Medline, Web of Science, CINAHL, PsychINFO, Embase- Non-Medline, Scopus, and the Cochrane Library, were systematically searched from 2001 to 2020. The search strategy included keywords and MeSH terms to identify relevant studies written in English.
Results
Eight articles were included in the review. Four key themes were synthesised from the findings: nurses need training and up to date information, providing support for patients, patient motivation to engage with treatment plans and perceived lack of time.
Conclusion
Nurses described the importance of training to help them support patients to engage as effectively as possible and their role in providing social and psychological support. They also described the importance of patient motivation to engage in a treatment and plan and sustain engagement and time.

Abstract
Members of 14-3-3 protein family are involved in the proper operation of Fe acquisition mechanisms at physiological and gene expression levels in Arabidopsis thaliana. To more directly and effectively observe whether members of 14-3-3 non-epsilon group have a function in Fe-deficiency adaptation, three higher order quadruple KOs, kappa/lambda/phi/chi (klpc), kappa/lambda/upsilon/nu(klun), and upsilon/nu/phi/chi (unpc) were generated and applied for physiological analysis in this study. The mutant plants that combine kl with un (klun) or kl with pc (klpc) mutations showed a better Fe uptake than Wt plants at low medium Fe, while this phenotype was absent in unpc mutant. The higher Fe uptake by klun correlated with a higher Fe-deficiency induced expression of selected Fe-related genes. The dynamics of 14-3-3-client interactions analysis showed that a subset of 27 proteins differentially interacted with 14-3-3 in roots caused by Fe deficiency. Many of these Fe responsive proteins have a role in glycolysis and TCA cycle, the FoF1-synthase and in the cysteine/methionine synthesis. Also, the 14-3-3 interactome of the klun roots showed significant differences with that of Wt roots under Fe sufficient conditions, where most of these differential binding proteins showed enhanced binding in the klun mutant. Nevertheless, a clear explanation for the observed phenotypes awaits a more detailed analysis of the functional aspects of 14-3-3 binding to the target proteins identified in this study.

Abstract
Background. There is a risk of novel mutations of SARS-CoV-2 that may render COVID-19 resistant to most of the therapies, including antiviral drugs. The evidence around the application of therapeutic plasma exchange (TPE) for the management of critically ill COVID-19 patients is still provisional and further investigations are needed to confirm its eventual beneficial effects. Methods. We therefore carried out a single-centered retrospective observational non-placebo-controlled trial enrolling 73 inpatients from Baqiyatallah Hospital in Tehran (Iran) with diagnosis of COVID-19 pneumonia confirmed by real-time polymerase chain reaction (RT-PCR) on nasopharyngeal swabs and high-resolution computerized tomography chest scan. These patients were broken down into two groups: Group 1 (30 patients) receiving standard of care (corticosteroids, ceftriaxone, azithromycin, pantoprazole, hydroxychloroquine, lopinavir/ritonavir); and Group 2 (43 patients) receiving the above regimen plus TPE (replacing 2 liter of patients’ plasma by a solution, 50% of normal plasma and 50% of albumin at 5%) administered according to various time schedules. The follow-up time was 30 days and all-cause mortality was the endpoint. Results. Deaths were 6 (14%) in Group 2 and 14 (47%) in Group 1. However, different harmful risk factors prevailed among patients not receiving TPE rather than being equally split between the intervention and control group. We used an algorithm of Structural Equation Modeling (of STATA) to summarize a large pool of potential confounders into a single score (called with the descriptive name “severity”). Disease severity was significantly (Wilkinson rank sum test p-value=0.0000) lower among COVID-19 patients undergoing TPE (median: -2.82; range: -5.18; 7.96) as compared to those non receiving TPE (median: -1.35; range: -3.89; 8.84), confirming that treatment assignment involved a selection bias of patients according to the severity of COVID-19 at hospital admission. The adjustment for confounding was carried out using severity as covariate in Cox regression models. The univariate Hazard Ratio (HR) of 0.68 (95%CI: 0.26; 1.80; p=0.441) for TPE turned to 1.19 (95%CI: 0.43; 3.29; p=0.741) after adjusting for severity. Conclusions. The lower mortality observed among patients receiving TPE was due to a lower severity of COVID-19 rather than TPE effects.

Authors: Szakmany Tamas , Hollinghurst Joe , Pugh Richard , Akbari Ashley , Griffiths Rowena , Bailey Rowena , Lyons Ronan A 
Published: April 2021

Abstract
Background: The ideal method of identifying frailty is uncertain, and data on long-term outcomes is relatively limited. We examined frailty indices derived from population-scale linked data on Intensive Care Unit (ICU) and hospitalised non-ICU patients with pneumonia to elucidate the influence of frailty on mortality.Methods: Longitudinal cohort study between 2010-2018 using population-scale anonymised data linkage of healthcare records for adults admitted to hospital with pneumonia in Wales. Primary outcome was in-patient mortality. Age, hospital frailty risk score (HFRS), electronic frailty index (eFI), Charlson comorbidity index (CCI), and social deprivation index were entered in the multivariate regression models.Results: Of the 107,188 patients, mean (SD) age was 72.6 (16.6) years, 50% were men. The two frailty indices and the comorbidity index had an increased risk of mortality for individuals with an ICU admission. Advancing age, increased frailty and comorbidity affected short- and long-term mortality. For predicting inpatient deaths, the CCI and HFRS based models were similar, however for longer term outcomes the CCI based model was superior. Discussion: Frailty and comorbidity are significant risk factors for patients admitted to hospital with pneumonia. Frailty and comorbidity scores based on administrative data have only moderate ability to predict outcome.

Published: April 2021

Abstract
The solar system characteristics are affected due to few obscure terms, causing a reduction of photovoltaic system's power output. Also, partial shaded conditions (PSCs) lead to several peaks on photovoltaic (PV) curves, which decrease conventional techniques' efficiency Also, in these (PSCs), standard equations might not be implemented entirely. Therefore, this study aims, first to modify and re-establish the mathematical model of PV array under (PSCs). Second, heuristic algorithms (Cuckoo Search Algorithm (CSA) and Modified Particle Swarm Optimization (MPSO)) have been suggested and applied with PV system to promote output power under varying weather conditions and PSCs. Moreover, these algorithms can improve the dynamic response and steady-state PV systems' performance simultaneously and effectively. Later on, the following approaches, modified (MP&O) and (ANN), are also proposed to extract the photovoltaic system's maximum power. Then, MPPT problem is modeled and optimized on MATLAB environment where it is reliable to connect the programmable optimizer with Simulink of photovoltaic cell used to validate results. Finally, proposed methods are examined under several scenarios for (PSCs) to investigate its effectiveness. The results ensure that proposed tracker based on CSA can distinguish between the global and local maximum peaks of PV system effectively comparing to others MPPT approaches.

Published: April 2021

Abstract
Integrated Kerr micro-combs are a powerful source of multiple wavelength channels for photonic radio frequency (RF) and microwave signal processing, particularly for transversal filter systems. They offer significant advantages featuring a compact device footprint, high versatility, large numbers of wavelengths, and wide Nyquist bands. We present our recent progress on photonic RF and microwave high bandwidth temporal signal processing based on Kerr micro-combs with comb spacings from 49GHz to 200GHz. We focus on integral and fractional Hilbert transforms, differentiators as well as integrators. The future potential of optical micro-combs for RF photonic applications in terms of functionality and ability to realize integrated solutions is also discussed.
Trends in Positive, Negative, and Neutral Themes of Popular Music From 1998 to 2018: Observational Study
Authors: Kwon Lois , Medina Daniela , Ghattas Fady , Reyes Lilia 
Published: April 2021

Background
Across the United States, the incidence of adolescent depression and suicide cases has risen in the past 10 years. Despite the risk factors and causes being multifactorial, the influence of popular culture on society and adolescents in this media-driven generation cannot be mitigated. Although the impact of social media and its effect on shaping self-identity in adolescents have been observed, the impact of music and its potential for subliminal negative messages to adolescents remains unclear.

Objective
This study analyzes the lyrics and music videos of the most popular music of multiple genres to quantify the frequencies of varying music theme trends.

Methods
The frequencies of themes of 1052 total American and Latin songs were collected from the Nielsen Music and Billboard’s top 100 chart performance from 1998 to 2018 for hip hop/rhythm and blues (R&B), pop, Latin, country, and rock/metal genres. Themes from songs were identified, quantified, and categorized with a rubric into negative, neutral, and positive themes by 3 different reviewers. Analysis was performed using 2-tailed t tests and a generalized linear model.

Results
Popular songs were reviewed for positive, negative, and neutral themes in the following 3-year intervals for ease of analysis purposes: 1998 to 2000 (n=148), 2001 to 2003 (n=150), 2004 to 2006 (n=148), 2007 to 2009 (n=156), 2010 to 2012 (n= 150), 2013 to 2015 (n=150), and 2016 to 2018 (n=150). There was a significant 180% increase in the percentage of songs with negative themes between all the interval years and across all genres (P<.001), while there was no significant difference in the frequency of songs with positive (P=.54) or neutral (P=.26) themes by year. There were significant differences in the number of negative themes found across genres (P<.001), with hip hop/R&B having the highest frequency of 130 out of 208 (62.5%) of the negative themes when compared to each of the individual genres (P<.001).

Conclusions
This study shows there is an increase in the frequency of negative themes over the span of 20 years across all genres, with hip hop/R&B having the highest frequency among the genres. These findings point to the potential impact that music may have in popular culture and on society. Furthermore, these results can help shape discussions between caregivers and their adolescent dependents and between primary care providers and their adolescent patients.

Published: April 2021

El objetivo de este estudio es el de analizar los significados que se atribuyen a los términos psicomotricidad y educación física en la educación infantil (etapa 0-6 años) y las consecuencias que se desprende de ello.
La investigación se ha fundamentado en la tradición metodológica hermenéutica-interpretativa y el método de recogida de datos ha sido el estudio de caso. Las estrategias utilizadas para la obtención de la información han sido la entrevista en profundidad, el grupo de discusión y el diario de investigación.
Los resultados obtenidos hacen evidente la confusión terminológica-conceptual existente en relación a los términos educación física y psicomotricidad, derivándose en consecuencia una ambigüedad que está dificultando el desarrollo de la educación física en los centros escolares y de formación de profesorado de educación infantil.
Según los resultados obtenidos, la causa principal de dicha confusión es el desconocimiento conceptual del término psicomotricidad, el cual se utiliza habitualmente por tradición en esta etapa, asociándose con unas propuestas motrices adecuadas metodológicamente para la educación infantil, y del modelo actual de educación física, el cual es percibido de manera reduccionista, al asociarse generalmente con unas prácticas instructivas, al acondicionamiento físico y a la práctica deportiva, generando con ello la percepción que no es adecuada para esta etapa.

Published: April 2021

Objectives:
Measurement of hepatic vein pressures is the accepted gold standard for the evaluation of portal hypertension. This study was conducted to evaluate the correlation between hepatic vein pressure measurements and histologic findings from transjugular liver biopsies. The hypothesis was that higher hepatic venous pressure gradients would correlate with a histologic diagnosis of cirrhosis.

Material and Methods:
We identified all patients who underwent transjugular liver biopsies at our institution between January 2015 and December 2019. Of these, 178 patients who had undergone hemodynamic evaluations during the biopsy procedure were included in the study. Demographic information and laboratory data were extracted from the patients’ electronic medical records. The hepatic vein pressure gradient (HVPG) was determined by subtracting the free hepatic venous pressure from the wedged hepatic venous pressure (WHVP), and the portosystemic gradient (PSG) was determined by subtracting the right atrial pressure from the WHVP. HVPG and PSG were compared by linear regression analysis and by calculating their receiver operating characteristics (ROC).

Results:
HVPG and PSG measurements were significantly associated with cirrhosis, with area under the ROC curve of 0.79 and 0.78, respectively. At the optimal cutoff of 9 mmHg, sensitivity and specificity for HVPG were 71% and 83% for HVPG and 67 % and 81% for PSG, respectively. No statistical difference was observed between the two measurements.

Conclusion:
A transhepatic venous pressure gradient above a cutoff of 9 mmHg is predictive of histologic cirrhosis, regardless of whether it is expressed as HVPG or PSG, with acceptable to excellent performance characteristics.

Published: April 2021

El objetivo del trabajo fue analizar cómo afronta América Latina a diferencia del resto del mundo la pandemia del Coronavirus COVID-19 y consecuencias sanitarias ocasionan a la región. Tras la aparición en Asia del COVID-19, Europa y Estados Unidos hoy viven una expansión acelerada del virus y todo indica que la próxima región además de África podría ser América Latina. La pandemia golpea la región con escasas ventajas para enfrentar el virus, por un lado, en un apresurado intento de frenar la propagación ha tomado medidas radicales mucho antes que los norteamericanos y europeos. Este estudio demuestra que Latinoamérica posee un menor crecimiento económico por lo que afrontaría la pandemia con inferiores herramientas, principalmente con limitadas infraestructuras sanitarias y estancamiento económico además de frágiles gobiernos y con poca maniobra financiera para incrementar el gasto público. No obstante, los países del sur de América a diferencia del Caribe y Centroamérica tienen un periodo invernal y están por entrar hacia un periodo invernal lo cual en teoría favorece la expansión del virus.
Intercultural education in times of restricted travel: Lessons from the Gaza Strip
Authors: Imperiale Maria Grazia 
Published: April 2021

This article draws upon a research project on intercultural language education conducted online between 2014 and 2017 with people living in the Gaza Strip (Palestine). Because the Gaza Strip has been under blockade since 2007, people cannot travel in and out freely. This context thus prompts educators and scholars to reflect on intercultural competence from a context of protracted crisis and of forced immobility. This study considers pre-service and in-service English teachers’ understandings of intercultural competence and how these educators encourage intercultural communicative competence (ICC) in their classrooms in the Gaza Strip, where neither teachers, nor students, may have travelled abroad or experienced a face-to-face intercultural encounter. Based on this analysis, this article argues that frameworks for intercultural education and ICC need to capture non-movement and the lack of face-to-face intercultural encounters as agentic in definitions of interculturality. In other words, ICC should be conceptualised in terms of the actual freedoms and opportunities that individuals have to develop and nurture it. In order to propose such a model, this article connects ICC with the capabilities approach (Nussbaum, 2011; Sen, 1999), the capability of mobility (de Haas, 2010), and with the capacity to aspire (Appadurai, 2004).

Published: April 2021

Oryzias woworae is an endemic fish of Sulawesi. This endemic fish naturally had faced endangered illegal and unlawful capture, therefore it is needed to be protected and conserved by a cultivation system. This research aims to provide basic information related to the cultivation of O. woworae to know the optimum salinity of hatching media and its influence on the hatchability of eggs and the length of time hatching O. woworae. This research was conducted using experimental methods and presented descriptively. The treatment used in this study is 0 ppt, 2-4 pt, 6-8 ppt, 10-12 ppt. The results showed that O. woworae eggs can hatch in salinity 0 ppt until 10-12 ppt and the best salinity for the length of hatching time is treatment of 2-4 ppt which is 7th day 14 hours 20 minutes. Treatment 0 ppt, 2-4 ppt and 6-8 ppt can reach 100%. This can be concluded that the optimum salinity of the hatching rate of Oryzias woworae until 6-8 ppt, but in treatment 10-12 ppt hatchability only gets 80% as some embryos become shrinking. Hatchability per day shows the treatment of 2-4 ppt is the best treatment, on the 7th day as much as 40% and on the 8th day as much as 40%. The optimal salinity for hatching O. woworae eggs is ÃÂ 2-4 ppt treatment, salinity that can expedite the length of hatching time and produce ÃÂ hatching rate by 100%.ÃÂ ÃÂ
