Patient-Reported Symptoms and Subsequent Risk of Myocardial Infarction in Chronic Kidney Disease
Authors: Lidgard Benjamin , Zelnick Leila R. , O’Brien Kevin D. , Bansal Nisha 
Published: March 2022

Background and objectives
Although patient-reported symptoms often precede acute presentations of cardiovascular disease, patients with nondialysis-requiring CKD are less likely to have typical symptoms of atherosclerotic disease when presenting with acute myocardial infarction. However, the associations between typical atherosclerotic symptoms and subsequent risk of myocardial infarction are unknown in ambulatory patients with CKD.

Design, setting, participants, & measurements
To determine whether typical atherosclerotic symptoms are associated with risk for subsequent myocardial infarction in people with CKD, we examined participants from the Chronic Renal Insufficiency Cohort Study. Chest pain, shortness of breath, and inability to climb stairs were evaluated annually using the Kidney Disease Quality of Life Instrument. Associations between categorical time-updated symptoms and physician-adjudicated incident myocardial infarction were assessed using Cox regression models.

Results
Among 3910 participants (mean age of 58±11 years; mean eGFR =44±15 ml/min per 1.73 m2), there were 476 incident myocardial infarctions over a median follow-up period of 10.4 years (interquartile range, 5.36–12.6 years). Median time from symptom assessment to incident myocardial infarction was 213 days (interquartile range, 111–333 days). Compared with no symptoms, mild, and moderate or worse, symptoms of chest pain (hazard ratio, 1.30; 95% confidence interval, 1.01 to 1.67; and hazard ratio, 1.70; 95% confidence interval, 1.27 to 2.27, respectively) and shortness of breath (hazard ratio, 1.37; 95% confidence interval, 1.10 to 1.70; and hazard ratio, 1.33; 95% confidence interval, 1.05 to 1.69, respectively) were significantly associated with greater risks for subsequent myocardial infarction. Participants reporting mild and severe limitations in climbing stairs (versus no limitation) had significantly higher adjusted risk of myocardial infarction (hazard ratio, 1.44; 95% confidence interval, 1.10 to 1.89; and hazard ratio, 1.89; 95% confidence interval, 1.44 to 2.49, respectively).

Conclusions
In a large ambulatory cohort of adults with CKD, symptoms of atherosclerotic cardiovascular disease were strongly associated with a higher risk for subsequent myocardial infarction.

Authors: Lilić Ana , Petković Emilija , Đorđević Stefan , Hadžović Miljan 
Published: March 2022

Due to its appeal, sport has always been in the service of various social fields, both in a negative and a positive sense. A sedentary lifestyle has become noticeably dominant among students. The most frequent external barrier for taking part in physical activities among the student population is a lack of time due to their schedules or due to familial or other obligations. The aim of the research was to use a critical analysis of existing studies and a generalization of the results of all the analysed papers which studied the effectiveness of sport to show the effects of sport and physical activity (PA) on the improvement of the mental hygiene among the student population. The literature was compiled by searching the following databases: Medline, Google Scholar, Web of Science and PubMed. The database search resulted in 198 papers of which 15 were included in the systematic review. The participants included in the systematic review were adults who attended class and were university students. An awareness of health and the positive effects of PA can be a decisive factor for motivating people to become physically more active. PA can help in the prevention and continuation of psychological wellbeing.

Authors: Arguelles Toache Eugenio 
Published: March 2022

Objetivo: determinar en qué medida existe un consenso en la literatura sobre la caracterización de las diferentes etapas de desarrollo del gobierno electrónico en función de cuatro categorías: las tecnologías empleadas, los objetivos perseguidos, los resultados/servicios obtenidos y el tipo de interacción con los usuarios. Diseño metodológico: se realizó una revisión cualitativa y sistematizada de la literatura científica que aborda las etapas de desarrollo del gobierno electrónico, para buscar definiciones puntuales sobre dichas etapas que, al ser contrastadas y analizadas, permitieron determinar los puntos convergentes.Resultados: existe amplio consenso entre los autores en cuanto a las características del gobierno electrónico 1.0 y 2.0, cierto consenso con respecto al gobierno electrónico 3.0, mientras que no existe suficiente información para determinar el consenso sobre el gobierno electrónico 4.0. Limitaciones de la investigación: el análisis efectuado se centró en las definiciones puntuales sobre las etapas de desarrollo del gobierno electrónico contenidas en los documentos científicos revisados, es necesario hacer un análisis más profundo de estos documentos para determinar con mayor rigor el consenso sobre las características de dichas etapas. Hallazgos: el estudio científico sobre las etapas de desarrollo del gobierno electrónico es relativamente reciente y, en la actualidad, gran parte de los trabajos se enfocan en desarrollar y analizar la discusión teórica, poniendo relativamente menos atención en la evidencia empírica, por ello algunas de las etapas de desarrollo del gobierno electrónico son consideradas prospectivamente.

Authors: Ferreira Marco , Manokore Viola , Gray Morag 
Published: March 2022

The aim of this article is to learn about teamwork in an online learning environment. to achieve this purpose, we developed a questionnaire based on three initial concepts, learning team process, learning teamwork impact, and tutor’s facilitation of learning teamwork. The PIT questionnaire is an instrument that could be used to identify critical factors that online students perceived as important in enhancing their learning and improve their experiences. We used some open-ended questions to support the questionnaire’s items analysis. We claim that learning team processes as well as tutor’s facilitations does have an impact on students’ experiences and learning. For a purposeful learning team, members should set clear goals outlining expectations and that every member should feel a sense of belonging and safe to contribute their ideas. The learning teamwork impact component contributed for the most variance in the PIT questionnaire. Apart from learning content, students indicated that with learning teams they gained collaborative skills, felt motivated and learned pertinent concepts from their peers from different backgrounds. We conclude that online learning teams are a form of community of learners, a place where students and tutors are actively and intentionally constructing knowledge together.
