Blending online learning with traditional approaches: changing practices

Considerable claims have been made for the development of e-learning, either as stand-alone programmes or alongside more traditional approaches to teaching and learning, for students across school and tertiary education. National initiatives have improved the position of schools in terms of access to hardware and electronic networking, software and educational resources, and staff development. The potential of e-learning to improve learning and teaching, and in turn, attainment, may be contested by academics but the policy makers are generally positive. Many countries across Europe and North America have adopted information and communication technology (ICT) as a central plank in school improvement and effectiveness planning. At the centre, however, remain the teacher and the learner. The impact of ICT on the learning experience will depend upon the roles adopted by each, the model of the learner held by the teacher and the pedagogy adopted. This paper considers the ways in which teachers and students responded to the implementation of one particular online programme and considers the approaches adopted and the attitudes to its use. The SCHOLAR programme is designed to complement rather than replace traditional teaching and learning approaches within schools and is aimed at students in the post-compulsory years of secondary school working towards external certification. It has a number of features including course materials, revision exercises, self-assessment facilities and a discussion forum. The independent evaluation of SCHOLAR looked at the impact that its use made on learning and teaching in the post-16 classroom and the differing ways in which teachers and students used the various elements of the programme. While it did appear to have a positive impact on attainment, the evidence indicates that this might have been greater had the teachers modified their practice, blending learning through SCHOLAR with more traditional methods.
Review of 90Y-ibritumomab tiuxetan as first-line consolidation radio-immunotherapy for B-cell follicular non-Hodgkin’s lymphoma

Several studies have indicated that radioimmunotherapy is an effective and clinically relevant complementary therapeutic approach for patients with B-cell non-Hodgkin’s lymphoma (NHL) and may convert partial to complete response when given as consolidation after induction chemotherapy. Yttrium-90(90Y)-ibritumomab tiuxetan (90Y-IT, Zevalin®, Y2B8) has documented efficacy for both indolent and aggressive NHL. Patients considered eligible for 90Y-IT treatment should satisfy several screening criteria. A recently completed randomized study for patients with follicular lymphoma has demonstrated that 90Y-ibritumomab consolidation also produced a marked prolongation of the median time to progression from 13.5 to 37 months, while partial responders seem to derive relatively more benefit. Other published and ongoing studies explore a similar use for patients with aggressive lymphoma. Studies are comparing the use of 90Y-IT consolidation with the anti-CD20 antibody rituximab maintenance, which is also gaining acceptance. In conclusion, the documented benefit of radioimmunotherapy should be viewed in the context of the goals of treatment and the changing standards of care for lymphoma.
Human Immunodeficiency Virus and Atherosclerosis

The advent of highly active antiretroviral therapy has led to a significant decline in the incidence of mortality and progression to AIDS in HIV-infection. With increased life expectancy, HIV-infected individuals are being affected by cardiovascular disease. Research studies have identified an increased prevalence of traditional coronary risk factors in HIV-infected patients. Additional investigations suggest that the virus itself may independently result in atherosclerosis. Further studies have linked the use of highly active antiretroviral therapy to the atherosclerotic processes. These findings suggest the need to reconsider HIV as one of the traditionally accepted risk factors for coronary artery disease, with treatment aimed at prevention of myocardial infarction.
Prebiotic Effect of an Infant Formula Supplemented with Galacto-Oligosaccharides: Randomized Multicenter Trial

Objective: The objective of the study was to investigate the effects of a galacto-oligosaccharides (GOS)-supplemented formula on the intestinal microbiota in healthy term infants, with a specific consideration for gastrointestinal symptoms as colic, stool frequency and consistency, regurgitation. Methods: This was a randomized, double-blind, controlled, parallel-group clinical trial performed simultaneously by 6 centers in Italy. Three groups were considered: breastfed, formula-fed, and GOS-supplemented formula-fed infants. Formula-fed infants were randomized to receive either the control or the study formula and consume the assigned formula exclusively until the introduction of complementary feeding. The nutritional composition of the 2 formulas were identical, apart from the supplemented GOS (0.4 g/100 mL) in the study formula. Four different types of bacteria were evaluated in order to assess the efficacy of GOS-supplemented formula on infants: Bifidobacterium, Lactobacillus, and Clostridium, Escherichia coli. Results: A total of 199 breastfed infants and 163 formula-fed infants were recruited. When considering stool frequency and consistency, GOS-supplemented formula presented normal and soft stools in the majority of episodes (89%). In the supplemented group the incidence of colic was lower with respect to the control group. A significantly lower count of Clostridium and a higher count of Bifidobacterium were found when comparing study formula and control formula in infants with colic. In children with colic the ratio between Clostridium count and Bifidobacterium and Lactobacillus count was in favor of the latter two when considering the GOS-supplemented formula group with respect to the control one. Conclusions: The prebiotic-supplemented formula mimicked the effect of human milk in promoting Bifidobacterium and Lactobacillus growth and in inhibiting Clostridium growth, resulting in a significantly lower presence of colic.
Teaching software engineering by means of computer-game development: Challenges and opportunities

Software-engineering education programs are intended to prepare students for a field that involves rapidly changing conditions and expectations. Thus, there is always a danger that the skills and the knowledge provided may soon become obsolete. This paper describes results and draws on experiences from the implementation of a computer game-development course whose design addresses problems in software-engineering education by improving students' abilities in four areas: (1) problem solving; (2) the application of previously learned knowledge; (3) the use of independent learning; and (4) learning by doing. In order to better understand this course's effect on students' performance in a software-development project, I investigated 125 students' performance in a 1-year senior-project course. Results of this study show that the students who had taken the computer game-development course became more successful in the senior-project course than the students who had not taken it.

The effects of the coordination support on shared mental models and coordinated action

The purpose of this study was to examine the effects of coordination support (tool support and tutor support) on the development of shared mental models (SMMs) and coordinated action in a computer-supported collaborative learning environment. Eighteen students were randomly assigned to one of three conditions, including the tool condition, the tutor condition, and the control condition (two groups per condition). Groups in the tool condition were given the task management tools; groups in the tutor condition received assistance from a tutor about coordination; and the control groups did not receive any support. SMMs were assessed on a 5-point Likert scale and coordinated action was analysed by examining learners' logfiles. The findings of this study suggest that tool support facilitates the development of SMMs and promotes coordinated action of each group.
Paclitaxel‐eluting balloon: From bench to bed

Since the first clinical angioplasty by Gruntzig in 1977, restenosis has been the primary drawback of percutaneous coronary intervention (PCI). In the balloon era. restenosis was correlated with elastic recoil and negative remodeling of the arterial wall. Later, introduction of stents proved to be a significant advance in reducing the elastic recoil and negative remodeling at the treatment site but stimulated proliferation, migration of smooth muscle cells, and neointimal hyperplasia, thereby generating a new type of restenosis, in‐stent restenosis. Brachytherapy and drug‐eluting stents (DES) may be considered the two breakthroughs against neointimal hyperplasia. However, concerns about stent thrombosis and incomplete elimination of in‐stent restenosis with DES in complex lesions and patients justify the pursuit of research in this field. Non‐stent based local drug delivery and particularly the use of paclitaxel‐eluting balloons could be one of these strategies. We aimed to review the concept, preclinical‐, and clinical data available with non‐stent based local drug delivery and, in particular, with paclitaxel‐eluting balloons. © 2009 Wiley‐Liss, Inc.
Functions of Coenzyme Q10 Supplementation on Liver Enzymes, Markers of Systemic Inflammation, and Adipokines in Patients Affected by Nonalcoholic Fatty Liver Disease: A Double-Blind, Placebo-Controlled, Randomized Clinical Trial

Background: Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disorder related to inflammation. Coenzyme Q10 (CoQ10) is a natural compound that has recently been considered as an anti-inflammatory factor. In the current study we aimed to evaluate the effects of CoQ10 supplementation on liver enzymes, inflammation status, and adipokines in patients with NAFLD. Methods: Forty-one subjects with NAFLD participated in the current randomized, double-blind, placebo-controlled trial. The participants were randomly divided into 2 groups: one group received CoQ10 capsules (100 mg once a day) and the other received placebo for 12 weeks. Blood samples of each patient were taken before and after the 12-week intervention period for measurement of liver aminotransferases, inflammatory biomarkers, and adipokines (adiponectin and leptin). Results: Taking 100 mg CoQ10 supplement daily resulted in a significant decrease in liver aminotransferases (aspartate aminotransferase [AST] and gamma-glutamyl transpeptidase [GGT]), high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor α, and the grades of NAFLD in the CoQ10 group in comparison to the control group (p < 0.05). In addition, patients who received CoQ10 supplement had higher serum levels of adiponectin (p = 0.016) and considerable changes in serum leptin (p = 0.053). However, no significant changes occurred in serum levels of interleukin-6 in both groups. Conclusion: The present study suggested that CoQ10 supplement at a dosage of 100 mg could be effective for improving the systemic inflammation and biochemical variables in NAFLD.
Depression and Cardiac Disease: A Review

Depression is highly prevalent in cardiac patients, with 20% to 40% of patients meeting criteria for major depressive disorder or experiencing an elevation in depressive symptoms. These depressive symptoms are often chronic and persistent, and they have been associated with the development and progression of coronary artery disease, worse health-related quality of life, poor physical functioning, recurrent cardiac events, and a 2- to 2.5-fold increased risk of mortality. Impaired adherence to health behaviors and adverse physiological effects of depression, including inflammation, endothelial dysfunction, platelet hyperactivity, and autonomic nervous system abnormalities, may link depression with adverse cardiac outcomes. Pharmacologic and psychotherapeutic interventions appear to be safe and effective at reducing depressive symptoms in patients with cardiovascular disease and may impact cardiac outcomes. Unfortunately, depression often is unrecognized and untreated in this population, despite the availability of brief screening tools that can be used for this purpose. We recommend the routine screening of cardiac patients for depression when there are adequate mechanisms for management and referral, such as available consulting psychiatrists or care management programs that facilitate the delivery of pharmacologic and psychotherapeutic treatments in this vulnerable population.
Low Adherence to Dietary Guidelines in Spain, Especially in the Overweight/Obese Population: The ANIBES Study

ABSTRACT Objective: The objective of this study was to analyze the dietary intake of the Spanish population according to ponderal status and body fat distribution. Methods: Data were obtained from ANIBES (Anthropometry, Intake, and Energy Balance in Spain), a cross-sectional study of a nationally representative sample (1013 men, 996 women) of the Spanish population (18–64 years). The final fieldwork was carried out from mid-September to November (three months) 2013. A 3-day dietary record provided information about food and beverage consumption. Height, weight, and waist circumference were assessed, and body mass index (BMI) and waist–height ratio (WHtR) calculated. Results: The Spanish population had a low consumption of fruits and vegetables, cereals, whole cereals, and dairy and high consumption of meat products. Individuals with overweight/obesity (BMI ≥ 25 kg/m2) and abdominal adiposity (WHtR ≥ 0.5) showed lower compliance with dietary guidelines. In the male group, adjusting by age, inadequate consumption of cereals (<4 servings/day) and vegetables and fruit (<5 servings/day) was associated with higher risk of overweight (odds ratio [OR] = 1.704, 95% confidence interval [CI], 1.187–2.447, p = 0.001, for cereals and OR = 3.816, 95% CI, 1.947–7.480, p = 0.001, for vegetables and fruits) and abdominal adiposity (OR = 2.081, 95% CI, 1.419–3.053, p = 0.000 and OR = 4.289, 95% CI, 2.108–8.726, p = 0.001, respectively). Conclusion: Nutritional campaigns should be conducted to improve the dietary habits of the Spanish population in general, especially men, who have poorer ponderal status and abdominal adiposity, due to their lower adherence to dietary guidelines.
It hinges on the door: Time, spaces and identity in Australian Aboriginal Health services

Abstract This paper explores how the structuring of places and time influence Aboriginal and Torres Strait Islander patient and carer experiences of health services. Face-to-face in-depth interviews were conducted with urban Aboriginal and Torres Strait Islander people with diabetes, chronic heart failure or chronic obstructive pulmonary disease as well as family carers (N = 19). Content analysis was undertaken. Participants report that each element of the time spent in Aboriginal Medical Services is seen as more valuable and worthwhile than in mainstream health services, from social and health sharing experiences in the waiting room to health care in clinical places; and that users feel they can rely on sufficient time and respectful care in their clinical consultation. Purposeful design of both physical and temporal aspects of health services is called for. We suggest re-introducing opportunities for spatiotemporal design in health care that have been limited by the segmented ‘person as illness’ design features of Australia’s current mainstream health system.
Nursing home residents with Alzheimer’s disease in special care units compared to other residents with Alzheimer’s disease

The purpose of the study was to compare nursing home residents with Alzheimer’s disease (AD) in special care units (SCUs) to other AD residents. We analyzed 49,627 admission assessments recorded in the Minimum Data Set during 2000 for residents with AD, with 11,311 in SCUs. We compared these two groups of AD residents for demographic characteristics, health status, and treatments. SCU residents were significantly more likely to be male, younger, white, married, and self pay than other AD residents. SCU residents were significantly more likely to have poorer cognitive function and communication skills while other AD residents were significantly more likely to be totally activities of daily living (ADL) dependent, more physically disabled, and have cardiac-related conditions. SCU residents were significantly more likely to receive daily anti-psychotic, anti-anxiety, or anti-depressant medications than other AD residents. Other AD residents were more likely to receive a range of treatments and procedures, while SCU residents were more likely to receive intervention programs for mood, behavior, or cognitive loss. The implications of this are that SCU residents and other AD residents represent distinct nursing home populations. SCU residents are more likely to have cognitive decline and behavior problems while other AD residents are more likely to have greater physical disability and life-threatening co-morbidities.
Growth Hormone and the Cardiovascular System

Growth hormone (GH) exerts its effects through insulin-like growth factor-1, and although ubiquitous in human tissues, it has a significant role in cardiovascular function. In recent years, there has been a great deal of interest in GH as an etiologic factor in many cardiovascular disease states. Acromegaly, a state of endogenous GH excess, results in myocardial hypertrophy and decreased cardiac performance with increased cardiovascular mortality. Additional insight into the role of excess GH on the cardiovascular system has been gained from data collected in athletes doping with GH. Likewise, GH deficiency is associated with increased mortality, possibly from the associated increase in atherosclerosis, lipid abnormalities, and endothelial dysfunction. However, further research is required to clarify the benefit of GH treatment in both deficient states and in heart failure patients.
Weight Changes and Metabolic Outcomes in Calorie-Restricted Obese Mice Fed High-Fat Diets Containing Corn or Flaxseed Oil: Physiological Role of Sugar Replacement with Polyphenol-Rich Grape

ABSTRACT Objective: Because diet components are important during dieting in obesity treatment, we examined possible beneficial effects of substituting corn oil and sugar with flaxseed oil and grape in calorie-restricted high-fat diets on weight changes as well as improvement in some metabolic markers and related gene expression. Methods: Seventy-five C57BL/6J male mice were given free access to a high-fat (36% of energy from fat) diet containing corn oil plus sugar (CO + S). After 11 weeks, 15 mice were sacrificed and another 60 were divided among 4 high-fat diet groups with 30% calorie restriction (CR) for the next 12 weeks. The diets contained corn oil (CO) or flaxseed oil (FO) with sugar (S) or grape (G). Results: Despite CR, a weight loss trend was observed only during the first 4 weeks in all groups. CR did not significantly increase SIRT1 gene expression. Higher liver weight was observed in mice consuming FO (p < 0.05). Proliferator-activated receptor gamma (PPARγ) expression decreased in FO + G-CR significantly and even with a reduction of adiposity and higher adiponectin levels, fasting blood sugar (FBS) was significantly higher than in CO + G-CR. Grape intake increased Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) expression and decreased insulin resistance in CO + G-CR. Conclusions: Sugar replacement with polyphenol-rich grape along with CR improved glucose homeostasis, and substituting corn oil with flaxseed oil in obese mice reduced fat mass, but even with no change in adiponectin levels it could not decrease insulin resistance. However, none of the food item combinations facilitated weight reduction in the long-term CR. Therefore, regardless of the total calorie intake, different diet components and fat contents may have unexpected effects on metabolic regulation.
Low 25-Hydroxyvitamin D and Myofascial Pain: Association of Cancer, Colon Polyps, and Tendon Rupture

ABSTRACT Background: Myofascial pain that has been associated with cancer and increased risk of morbidity and mortality in cancer patients is intrinsically associated with low magnesium and low 25-hydroxyvitamin D (25(OH)D). Therefore, this physical finding was used as a clinical diagnostic proxy. Objective: The objective of this study was to assess the association and prevalence of disease in individuals with myofascial pain and low 25(OH)D in a county with low magnesium in the drinking water. Design: This is a retrospective cross-sectional study of a chart review of 269 subjects to assess subjects presenting with myofascial pain (assessed by tender trigger points) and 25(OH)D concentrations below 30 ng/mL or a history of 25(OH)D deficiency compared to those without these exposures. Results: The association between the exposure of low 25(OH)D levels and myofascial pain was compared to all cancers, colon polyps, and tendon ruptures. The odds of having cancer with the combined exposures was 10.14 times the odds of not having either exposure (95% confidence interval [CI], 5.08, 20.25, p < 0.001). For adenomatous colon polyps, the odds ratio (OR) was 7.24 (95% CI, 3.83, 13.69, p < 0.001), and for tendon rupture, the OR was 8.65 (95% CI, 3.76, 19.94, p < 0.001). Of 80 subjects who had both myofascial pain and 25(OH)D less than 30 ng/mL, 74 were tested for red blood cell (RBC) magnesium. Half of those subjects had RBC magnesium concentrations < 4.6 mg/dL, and 23% had levels below the reference range (4.0–6.4 mg/dL). Conclusion: Myofascial pain as assessed by tender trigger points and 25(OH)D deficiency showed a significant association with cancer, adenomatous colon polyps, and tendon rupture. Further studies to verify these results are needed, especially in areas where there is low magnesium in the drinking water.
Medico-Legal Issues in Cardiology

The aim of this article is to educate physicians about the current litigation climate in cardiology and cardiac surgery, with a focus on the most frequently litigated areas of practice, including failure to diagnose and treat myocardial infarction, coronary artery bypass graft surgery, percutaneous coronary intervention, and the use of tissue plasminogen activator. Empirical research on cardiology malpractice is presented, along with a sampling of up-to-date cases designed to illustrate common issues and important themes. The principles for reducing legal liability are also discussed, including the informed consent process, spoliation of records, and the role of documentation. Finally, practical recommendations are provided for cardiologists and cardiac surgeons to limit their legal liability.
