Affordance Theory in Social Media Research: Systematic Review and Synthesis of the Literature

Social media technologies continue transforming various dimensions of social and organisational life through possibilities they present for goal-oriented actions of diverse users/ user groups. The notion of affordances that explains these possibilities has witnessed popularity among IS scholars to study these technologies. However, since the concept itself has been under ongoing development, its use in studying social media technologies has been focused on identifying technical affordances, perception and actualisations of these affordances, or the social and organisational implications of such affordances. In this research-in-progress paper, we present our attempt to systematically review and synthesise the literature to examine the effects of social media affordances. In addition, we aim to systematically review the existing literature to explore how the concept of affordance has been employed in social media research, to uncover the effects of social media affordances and present a comprehensive framework of these affordances effects and identify areas for future research

Constant Connectivity and Boundary Management Behaviors: The role of Human agency

The surge of remote and hybrid work in the post-pandemic era reinforced the blurred boundaries between work and non-work responsibilities. Thus, how people manage the boundaries between work and non-work domains has become more complicated. This study advances the previous studies on constant connectivity by focusing on how employees’ perception of constant connectivity might actualize their boundary management behaviors. Additionally, we concentrated on contextual factors, including IT/internet policies, informal social norms, and work flexibility, to investigate how these factors could influence employees’ perception of constant connectivity. This paper reports a two-phase study. In the first phase, we used sentiment analysis to rank 38 internet use policies of Australian universities for grading their strictness toward ICT/internet use. Next, building on the first phase, we interviewed 28 academics. We identified three perceptions of constant connectivity, including constant connectivity as a resource, a challenge, and a duality. We also found five distinct boundary management behaviors connected to three different perceptions

Patients and Public Involvement in Patient Safety and Treatment Process in Hospitals Affiliated to Kashan University of Medical Sciences, Iran, 2013

Background: In the recent decades, healthcare providers had a perspective of benevolent paternalism. Nowadays, the patients’ role has changed and they have a significant obligation to participate in their caring decisions. Objectives: The current study aimed to investigate the involvement of patients and public in the patient safety and treatment process in hospitals affiliated to Kashan University of Medical Sciences, Kashan, Iran, 2013. Patients and Methods: A cross-sectional study was conducted in the hospitals affiliated to Kashan University of Medical Sciences in 2013. Subjects included all of the 18 chief managers, 10% of nurses in each hospital, and 375 patients. Data collection instruments included a questionnaire and a checklist designed according to the research objectives. Data analysis was performed using the SPSS ver. 13. Descriptive statistics, percentage and frequencies, were calculated for all variables and analyzed by Chi-square test. Results: In the treatment process, 81 patients (21.61%), 50 nurses (80.6%) and 15 chief managers (83.3%) had awareness about Patient Bill of Rights. In patient Safety, 19.73% of the patients stated that hospitals received their feedbacks. Management activities were weak in evaluation. All of the six hospitals (100%) had a defined process to perform satisfaction surveys’ quality improvement and patient authentication policy. Conclusions: Patient and public participation in Kashan hospitals are not adhered well. As the patient has an important role in improving the quality of services, more use of mass media especially local newspapers, hospital websites, and training programs are suggested to inform both the patients and public on their rights and roles in improving the healthcare services

Effect of iron repletion and correction of iron deficiency on thyroid function in iron-deficient Iranian adolescent girls

The aim of this study was to determine whether iron supplementation in iron-deficient adolescent girls would improve thyroid function. A double-blind clinical trial was performed in a region in southern I.R. Iran. A total of 103 iron deficient participants were chosen. In all, 94 participants successfully completed this study. Participants were randomly assigned to one of two groups and treated with a 300 mg ferrous sulfate 5 times/week (n = 47) and placebo 5 times/week (n = 47) for 12 weeks. Blood samples were collected and assayed for hemoglobin, hematocrit, serum ferritin, iron, total iron binding capacity (TIBC), Thyroid stimulating hormone (TSH), total thyroxine (TT4), total triiodothyronine (TT3), free thyroid hormones (FT4 and FT3), triiodothyronine resin uptake (T3RU), reverse triiodothyronine (rT3), selenium and albumin concentrations. Statistical analysis was performed with parametric and non-parametric methods as appropriate. Data analysis revealed a significant increase in TT4, TT3, T3RU and a significant decrease in rT3 concentration in comparison to initial values in iron treated group (12, p<0.001; 3.5, p<0.001; 16, p<0.05 and 47, p<0.001, respectively). At 12 week there were significant differences between control and placebo in TT4, TT3, T3RU and rT3 concentrations (9.9 vs 8.4 μg dL-1, 145.2 vs 130.4 μg dL-1, 32.5 vs 28.4 and 23 vs 41 μg dL-1, respectively, all p<0.001). Alterations in FT3 and TSH concentration were not significant, but concentration of FT4 revealed a significant difference between the beginning and the end of the study in iron treated group (10.3 vs 11.4, p<0.001). Iron supplementation improves some indices of thyroid function in iron-deficient adolescent girls. © 2007 Asian Network For Scientific Information

Extra virgin olive oil in maternal diet in, but high amount has deleterious effects creases osteogenic genes expression on bones in mice offspring at adolescence

Objective(s): Maternal high-fat diet has been shown to have deleterious effects on the offspring bones. However, there is no study to assess the effects of type and amount of maternal dietary oil in an isocaloric diet, with focus on extra virgin olive oil (EVOO). The objective of the current study was to test the hypothesis that type of maternal dietary oil has more effects than its amount in an isocaloric diet during gestation and lactation on bone genes expression in offspring in adolescence. Materials and Methods: Virgin female C57BL/6 mice were impregnated and fed either the AIN 93G diet (received 16 of calories as soybean oil, as a control diet, or EVOO) or a high fat AIN 93G diet (received 45 of calories as soybean oil or EVOO) from the time of vaginal plug confirmation until offspring�s weaning. Results: After adjusting for the amount of oils, osteoprotegerin/ receptor activator of nuclear factor NF-κB ligand (OPG/RANK-L) and OPG expressions were 6.1-and 2.8-folds higher in offspring born to EVOO compared with soybean oil-fed mothers. OPG, beta-catenin, and OPG/RANK-L expression were 88, 94, and 70 lower in offspring born to the 45 oil-fed mothers compared with the 16 group. In contrast, peroxisome proliferator-activated receptor gamma-2 (PPARγ2) gene expression was higher in the 45 oil group, adjusted for the types of oil. Conclusion: Maternal EVOO consumption, but not soybean oil increased osteoblastic gene expression, and high amounts of both oils decreased osteoblastic and increased adipogenic genes expression in adolescent offspring. � 2016, Mashhad University of Medical Sciences.

International Consensus on Differential Diagnosis and Management of Patients With Danon Disease: JACC State-of-the-Art Review

Danon disease is a rare X-linked autophagic vacuolar cardioskeletal myopathy associated with severe heart failure that can be accompanied with extracardiac neurologic, skeletal, and ophthalmologic manifestations. It is caused by loss of function variants in the LAMP2 gene and is among the most severe and penetrant of the genetic cardiomyopathies. Most patients with Danon disease will experience symptomatic heart failure. Male individuals generally present earlier than women and die of either heart failure or arrhythmia or receive a heart transplant by the third decade of life. Herein, the authors review the differential diagnosis of Danon disease, diagnostic criteria, natural history, management recommendations, and recent advances in treatment of this increasingly recognized and extremely morbid cardiomyopathy

European guideline on obesity care in patients with gastrointestinal and liver diseases – Joint ESPEN/UEG guideline

Background: Patients with chronic gastrointestinal (GI) disease such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, gastroesophageal reflux disease (GERD), pancreatitis, and chronic liver disease (CLD) often suffer from obesity because of coincidence (IBD, IBS, celiac disease) or related pathophysiology (GERD, pancreatitis and CLD). It is unclear if such patients need a particular diagnostic and treatment that differs from the needs of lean GI patients. The present guideline addresses this question according to current knowledge and evidence. Objective: The objective of the guideline is to give advice to all professionals working in the field of gastroenterology care including physicians, surgeons, dietitians and others how to handle patients with GI disease and obesity. Methods: The present guideline was developed according to the standard operating procedure for ESPEN guidelines, following the Scottish Intercollegiate Guidelines Network (SIGN) grading system (A, B, 0, and good practice point (GPP)). The procedure included an online voting (Delphi) and a final consensus conference. Results: In 100 recommendations (3x A, 33x B, 24x 0, 40x GPP, all with a consensus grade of 90% or more) care of GI patients with obesity – including sarcopenic obesity – is addressed in a multidisciplinary way. A particular emphasis is on CLD, especially fatty liver disease, since such diseases are closely related to obesity, whereas liver cirrhosis is rather associated with sarcopenic obesity. A special chapter is dedicated to obesity care in patients undergoing bariatric surgery. The guideline focuses on adults, not on children, for whom data are scarce. Whether some of the recommendations apply to children must be left to the judgment of the experienced pediatrician. Conclusion: The present guideline offers for the first time evidence-based advice how to care for patients with chronic GI diseases and concomitant obesity, an increasingly frequent constellation in clinical practice

Practical guideline on obesity care in patients with gastrointestinal and liver diseases – Joint ESPEN/UEG guideline

Background: Patients with chronic gastrointestinal disease such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, gastroesophageal reflux disease (GERD), pancreatitis, and chronic liver disease (CLD) often suffer from obesity because of coincidence (IBD, IBS, celiac disease) or related pathophysiology (GERD, pancreatitis and CLD). It is unclear if such patients need a particular diagnostic and treatment that differs from the needs of lean gastrointestinal patients. The present guideline addresses this question according to current knowledge and evidence. Objective: The present practical guideline is intended for clinicians and practitioners in general medicine, gastroenterology, surgery and other obesity management, including dietitians and focuses on obesity care in patients with chronic gastrointestinal diseases. Methods: The present practical guideline is the shortened version of a previously published scientific guideline developed according to the standard operating procedure for ESPEN guidelines. The content has been re-structured and transformed into flow-charts that allow a quick navigation through the text. Results: In 100 recommendations (3× A, 33× B, 24 × 0, 40× GPP, all with a consensus grade of 90% or more) care of gastrointestinal patients with obesity – including sarcopenic obesity – is addressed in a multidisciplinary way. A particular emphasis is on CLD, especially metabolic associated liver disease, since such diseases are closely related to obesity, whereas liver cirrhosis is rather associated with sarcopenic obesity. A special chapter is dedicated to obesity care in patients undergoing bariatric surgery. The guideline focuses on adults, not on children, for whom data are scarce. Whether some of the recommendations apply to children must be left to the judgment of the experienced pediatrician. Conclusion: The present practical guideline offers in a condensed way evidence-based advice how to care for patients with chronic gastrointestinal diseases and concomitant obesity, an increasingly frequent constellation in clinical practice
