Background The COVID-19 pandemic lead to a sudden shift to online teaching and restricted campus access. Aim To assess how university students experienced the sudden shift to online teaching after closure of campus due to the COVID-19 pandemic. Material and methods Students in Public Health Nutrition answered questionnaires two and 12 weeks (N = 79: response rate 20.3% and 26.6%, respectively) after the lockdown in Norway on 12 March 2020 and participated in digital focus group interviews in May 2020 (mixed methods study). Findings and discussion Two weeks into the lockdown, 75% of students reported that their life had become more difficult and 50% felt that learning outcomes would be harder to achieve due to the sudden shift to online education. Twelve weeks into the lockdown, the corresponding numbers were 57% and 71%, respectively. The most pressing concerns among students were a lack of social interaction, housing situations that were unfit for home office purposes, including insufficient data bandwidth, and an overall sense of reduced motivation and effort. The students collaborated well in digital groups but wanted smaller groups with students they knew rather than being randomly assigned to groups. Most students agreed that pre-recorded and streamed lectures, frequent virtual meetings and student response systems could improve learning outcomes in future digital courses. The preference for written home exams over online versions of previous on-campus exams was likely influenced by student’s familiarity with the former. The dropout rate remained unchanged compared to previous years. Conclusion The sudden shift to digital teaching was challenging for students, but it appears that they adapted quickly to the new situation. Although the concerns described by students in this study may only be representative for the period right after campus lockdown, the study provide the student perspective on a unique period of time in higher education.

We have compared the effects of partially hydrogenated fish oil (PHFO diet), partially hydrogenated soybean oil (PHSO diet), and butterfat (butter diet) on fibrinolytic and coagulation variables in 31 young men. The three test margarines, which contributed 78% of total fat in the diets, contained 70% butterfat, PHSO, or PHFO, each with 30% of soybean oil. Fat provided approximately 35% of energy, and the content of trans-fatty acids was 0.9%, 8.5%, and 8.0% of energy in the butter diet, PHSO diet, and PHFO diet, respectively. All diets contained 420 mg cholesterol per 10 megajoules per day. All subjects consumed all three test diets for 3 weeks, in a random order (crossover design). The PHSO diet resulted in higher levels of plasminogen activator inhibitor type 1 antigen and plasminogen activator inhibitor type 1 activity than the two other test diets. Fibrinogen increased on the butter diet compared with the PHFO diet. No significant differences in the levels of factor VII, fibrinopeptide A, D-dimer, tissue plasminogen activator or beta-thromboglobulin were observed between the three test diets. The PHFO and the PHSO diets have previously been shown to result in higher levels of Lp(a) compared with the butter diet. The present findings indicate that PHSO has unfavorable antifibrinolytic effects relative to PHFO and butter and that butter may be procoagulant relative to PHFO. More controlled studies are needed to assess definitely the impact of different hydrogenated fats on risk of coronary heart disease.

Aims and objectivesTo identify what nurses experience as barriers to ensuring adequate nutritional care for the undernourished hospitalized elderly.BackgroundUndernutrition occurs frequently among the hospitalised elderly and can result in a variety of negative consequences if not treated. Nevertheless, undernutrition is often unrecognised and undertreated. Nurses have a great responsibility for nutritional care, as this is part of the patient's basic needs. Exploring nurses' experiences of preventing and treating undernourishment among older patients in hospitals is therefore highly relevant.DesignA focus group study was employed based on a hermeneutic phenomenological methodological approach.MethodsFour focus group interviews with totally 16 nurses working in one large university hospital in Norway were conducted in spring 2012. The nurses were recruited from seven somatic wards, all with a high proportion of older (≥70 years) inpatients. The data were analysed in the three interpretative contexts: self-understanding, a critical common-sense understanding and a theoretical understanding.ResultsWe identified five themes that reflect barriers the nurses experience in relation to ensuring adequate nutritional care for the undernourished elderly: loneliness in nutritional care, a need for competence in nutritional care, low flexibility in food service practices, system failure in nutritional care and nutritional care is being ignored.ConclusionsThe results imply that nutritional care at the university hospital has its limits within the hospital structure and organisation, but also regarding the nurses' competence. Moreover, the barriers revealed that the undernourished elderly are not identified and treated properly as stipulated in the recommendations in the national guidelines on the prevention and treatment of undernutrition.Relevance to clinical practiceThe barriers revealed in this study are valuable when considering improvements to nutritional care practices on hospital wards to enable undernourished older inpatients to be identified and treated properly.

Background: Dietary calcium and antioxidants have been suggested as protective agents against colorectal cancer. This has been supported by animal experimental studies, case control and cohort studies. Materials and Methods: In a prospective intervention study of colorectal adenomas, and intermediary stage in colorectal carcinogenesis, 116 polyp-bearing patients received a placebo-controlled daily mixture of β-carotene 15 mg, vitamin C 150 mg, vitamin E 75 mg, selenium 101 µg, and calcium (1.6 g daily) as carbonate for a period of 3 years with annual colonoscopic follow-up to test if the mixture was able to reduce polyp growth or recurrence. All polyps of <10 mm at enrolment or follow-up were left unresected until the end of the study. Results: 87–91% of the patients attended the annual endoscopic follow-up investigations, and 19% of the patients dropped out of the medical intervention. The rest consumed 85% of the total amount of tablets over the 3 years. The fecal calcium concentration was 2.3–2.7 times higher in patients taking active medication compared to the placebo group. Diet registration showed that, when adding the intake of antioxidants and calcium from diet and intervention, there was a significant difference between the intake of these substances in the active and the placebo group. No difference was detected in the growth of adenomas between the active and the placebo group from year to year and for the total study period. Moreover, there was no effect on polyps of <5 or 5–9 mm, or on polyps in the different colonic segments analyzed separately. A reduced growth of adenomas was found in patients <60 years of age taking active medication (n = 8) compared to those taking placebo (n = 6; mean difference 2.3 mm; 95% CI 0.26–4.36). There was a significantly lower number of patients free of new adenomas in the placebo group compared to those taking active medication as tested by logistic regression and Kaplan-Meier analysis (log-rank test p value 0.035). Subgroup analysis showed that only the group of patients with no family history of colorectal cancer, those with only one adenoma at inclusion, and those <65 years benefitted from the intervention medication. Conclusion: The study did not find an overall effect on polyp growth. Our data, however, may support a protective role of calcium and antioxidants on new adenoma formation.
