AbstractThe role of statistical methods is now well recognized in health sciences since these disciplines are concerned with the study of communities or populations where the principles of sampling and statistical inference are clearly applicable. However, many medical and health sciences teachers and students have been slower to perceive the need for knowledge of biostatistical methods, even though all aspects of medical diagnosis and prognosis are governed by the laws of probability. Some of them are still skeptical about the value and importance of biostatistical principles to their fields and raise questions about the meaning, content, and nature of biostatistics and relevance of its teaching to health sciences disciplines. The purpose of this essay is to address some of these issues with the hope to invoke comments and responses from other biostatistics instructors who have encountered similar predicaments in their teaching and consulting roles to health sciences students and professionals.

The supervision of clinical placements is essential to achieving a positive learning experience in the clinical setting and which supports the professional training of those being supervised. The aim of this study was to explore health sciences students’ perceptions of the role of the supervisor in the supervision of clinical placements. A quantitative methodology was used, administering a previously validated questionnaire, by means of an expert panel and a pre-test, to 134 students from the Faculty of Nursing, Physiotherapy and Podiatry at the University of Seville (Spain). The analysis of variables was carried out by means of a data matrix. The results revealed a statistically significant difference in the perception of placement supervision depending on the degree, with Nursing producing the highest degree of affirmation in the variables studied and the greatest satisfaction with placement supervision; in contrast, Physiotherapy produced the greatest dissatisfaction and the lowest degree of affirmation. The study and analysis of these perceptions facilitates the collection of relevant information in order to formulate actions that help to improve the supervision experience during placements. They also allow a greater understanding of what factors most influence the experience of supervision during clinical placements.

The role of miR-21 in the pathogenesis of various liver diseases, together with the possibility of detecting microRNA in the circulation, makes miR-21 a potential biomarker for noninvasive detection. In this review, we summarize the potential utility of extracellular miR-21 in the clinical management of hepatic disease patients and compared it with the current clinical practice. MiR-21 shows screening and prognostic value for liver cancer. In liver cirrhosis, miR-21 may serve as a biomarker for the differentiating diagnosis and prognosis. MiR-21 is also a potential biomarker for the severity of hepatitis. We elucidate the disease condition under which miR-21 testing can reach the expected performance. Though miR-21 is a key regulator of liver diseases, microRNAs coordinate with each other in the complex regulatory network. As a result, the performance of miR-21 is better when combined with other microRNAs or classical biomarkers under certain clinical circumstances.

The COVID-19 pandemic has forced governments worldwide to produce solutions to the abruptly interrupted work in education. School systems appear to have responded rapidly, creating home schooling and online educational environments, where teachers and students would interact with safety. In this paper, we attempt a synthesis of Sen’s capability approach, Bourdieu’s theory of capital and Bernstein’s framework in order to theorize the relationships between home and school conditions and practices, and to analyse the data of the 2nd Survey of Schools: ICT in Education (a survey conducted in 2019 on behalf of the European Commission collecting data regarding digitalization in education and digital technologies in learning in the European Union). The survey is complemented by a second set of indicators provided by Eurostat to further investigate the availability and functionality of household space per family in selected European countries. We find significant differences in important social and environmental conversion factors, likely limiting children’s capability to benefit from digital schooling. The most important differences are found in regard to parents’ familiarity with information and communications technology use, while inequalities in environmental factors, such as overcrowded housing, are also existent. Overall, there are large inequalities within and between countries in Europe, which need to be addressed by policymakers.

The Impact

Today’s COVID-19 situation can affect university Health Sciences students’ psychological health. This study aimed to analyze the stress caused by the impact of the COVID-19 pandemic on Health Sciences students from the University of Zaragoza (Spain) almost 1 year after the pandemic began. This cross-sectional descriptive study was conducted with a sample of 252 university students who completed a self-administered online questionnaire. It evaluated the impact of perceived stress with a modified scale (PSS-10-C), and assessed anxiety and depression on the Goldberg scale. Students presented stress (13.1%), anxiety (71.4%) and depression (81%). Females (81.7%) and the third-year Occupational Therapy students (p = 0.010) reported perceived stress. Nursing students perceived less stress (OR: 0.148; 95% CI: 0.026 to 0.842). University students developed stress and anxiety due to COVID-19 almost 1 year after the pandemic began. Psychological support measures for these groups should be prioritized.

Hepatocellular carcinoma (HCC) remains one of the most lethal human cancer globally. For advanced HCC, curable plan for advanced HCC is yet to be established, and the prognosis remains poor. The detail mechanisms underlying the progression of HCC tumorigenicity and the corruption of tumor microenvironment (TME) is complex and inconclusive. A growing body of studies demonstrate microRNAs (miRs) are important regulators in the tumorigenicity and TME development. Notably, mounting evidences indicate miR-29a play a crucial role in exerting hepatoprotective effect on various types of stress and involved in the progression of HCC, which elucidates their potential theragnostic implications. In this review, we reviewed the advanced insights into the detail mechanisms by which miR-29a dictates carcinogenesis, epigenetic program, and metabolic adaptation, and implicated in the sponging activity of competitive endogenous RNAs (ceRNA) and the TME components in the scenario of HCC. Furthermore, we highlighted its clinical significance in diagnosis and prognosis, as well as the emerging therapeutics centered on the activation of miR-29a.

Since the crucial role of the microenvironment has been highlighted, many studies have been focused on the role of biomechanics in cancer cell growth and the invasion of the surrounding environment. Despite the search in recent years for molecular biomarkers to try to classify and stratify cancers, much effort needs to be made to take account of morphological and nanomechanical parameters that could provide supplementary information concerning tissue complexity adaptation during cancer development. The biomechanical properties of cancer cells and their surrounding extracellular matrix have actually been proposed as promising biomarkers for cancer diagnosis and prognosis. The present review first describes the main methods used to study the mechanical properties of cancer cells. Then, we address the nanomechanical description of cultured cancer cells and the crucial role of the cytoskeleton for biomechanics linked with cell morphology. Finally, we depict how studying interaction of tumor cells with their surrounding microenvironment is crucial to integrating biomechanical properties in our understanding of tumor growth and local invasion.
