- PURPOSE: To investigate the effect of granulocyte colony-stimulating factor (G-CSF)-supported chemotherapy on normal red bone marrow MR imaging in breast cancer patients with focal bone metastases. MATERIAL AND METHODS: Fifteen breast cancer patients who were examined before and after chemotherapy with T1-weighted-SE and long echo-time inversion-recovery turbo-spin-echo (long TE IR-TSE) sequences in the thoracolumbar spine and pelvis were retrospectively studied. Nine of them received G-CSF therapy after the administration of each chemotherapy course. Of these 9 patients, the MR follow-ups were performed during G-CSF in 4 patients and after G-CSF therapy in 5 patients. Six patients did not receive G-CSF. Signal intensity (SI) changes in normal bone marrow were evaluated visually in all patients and quantitatively in 13 patients. RESULTS: In all 4 patients investigated during G-CSF therapy a diffuse, homogeneous SI increase on long TE IR-TSE was observed visually and quantitatively in initially normal bone marrow. This change obscured some focal lesions in 2 patients. No such SI change was visible after G-CSF therapy (p = 0.008) or in patients not receiving G-CSF. On T1-weighted images an SI decrease was found both during and after G-CSF therapy, but an increase occurred in patients not receiving G-CSF. CONCLUSION: G-CSF-supported chemotherapy can induce diffuse SI changes in normal red bone marrow on MR imaging. On long TE IR-TSE, the changes are visible during G-CSF treatment and can lead to misinterpretations in the response evaluation of bone metastases to therapy.

- <i>Background/Aims:</i> Evidence underlines the importance of drinking patterns and individual characteristics in experiencing adverse alcohol-related consequences; however, little research has been conducted to explore who does and who does not experience consequences with similar drinking patterns. Using data from seven European countries, this study assesses the association between demographic and socioeconomic characteristics and six adverse consequences. <i>Methods:</i> Conditional logistic regression models were estimated, cases (experiencing a consequence) being matched to controls (not experiencing the consequence) by drinking patterns. <i>Results:</i> In general, protective effects with increasing age and being in a partnership were consistent. Gender effects were mixed, but mainly protective for women. Educational achievement and economic status showed consistent effects across countries, but different directions of effect across consequences. Consequences mostly associated with individual drinking pattern <i>(injury, blackout</i>, and <i>loss of control over drinking)</i> exhibited similar patterns of associations, but varying ones arose for consequences additionally influenced by societal reaction to drinking <i>(guilt</i>, <i>role failure</i>, and <i>pressure to cut down drinking)</i>. <i>Conclusion:</i> Differences in strengths and directions of effects across consequences pointed to the possibility that the reporting of adverse consequences is not only influenced by alcohol consumption, but also by attributional processes related to demographic and socioeconomic statuses.

- PURPOSE: To assess the diagnostic efficacy, safety and tolerability of mangafodipir trisodium (MnDPDP, Teslascan) in MR imaging of the liver. MATERIAL AND METHODS: Eighty-two patients from 4 centres underwent MR imaging with pre-contrast sequences including T1-weighted SE and GRE, and T2-weighted turbo SE sequences. MnDPDP at a dose of 5 mumol/kg b.w. was administered by slow i.v. infusion, and 20-60 min after infusion the T1-weighted SE and GRE sequences were repeated. Diagnostic efficacy was evaluated by counting the number of lesions and by evaluating whether more information for lesion characterisation was available in post-contrast images. Safety and tolerability were assessed by recording adverse events and infusion-related discomfort. RESULTS: Significantly more lesions were found in MnDPDP-enhanced T1-weighted SE and GRE images than in unenhanced images of the same sequences. More lesions were also found in these images compared with T2-weighted images at a level of marginal significance. More information was obtained from MnDPDP-enhanced images in 40 cases. Mild to moderate adverse events were experienced by 17% of the patients. CONCLUSION: MnDPDP-enhanced images can improve lesion detection in the liver and are helpful for lesion characterisation. To obtain optimal diagnostic information of liver lesions T2-weighted images are also valuable. MnDPDP is a safe contrast agent for MR imaging of liver lesions.

Tidskriftsartikel (refereegranskat)abstract
- In this study, we explored healthcare workers' (HCWs) worry perception and its association with their work situation during the first wave of the COVID-19 pandemic.A web-based multimethods survey including multiple choice and open-ended questions was used.The study was conducted at a university hospital in Sweden.All HCWs who were working during the first wave of the COVID-19 pandemic in March-June 2020 were eligible. HCWs (n=6484, response rate=41%) from 69 departments fulfilled the study inclusion criteria and responded to the survey. Of them, we analysed data from the 3532 participants who replied to the open-ended questions (54% of the respondents).Worry perception and its association with work conditions among HCWs.29% (n=1822) and 35% (n=2235) of the responding HCWs experienced a daily or more than daily strong worry of being infected or infecting others with SARS-CoV-2. This finding could be further confirmed and explored with themes from the qualitative results: 'ambiguity of feeling safe and secure', 'being obliged to adapt to a new reality' and 'into the unknown'. The themes consisted of 6 main categories and 15 subcategories. The findings revealed that the two main drivers of worry perceived by HCWs were lack of personal protective equipment and fear of bringing the virus home to their families and friends.Worries of getting infected are common among HCWs during crises such as the COVID-19 pandemic. Several factors are raised that plausibly could minimise the negative effects of worry among HCWs. Thus, effective preventive work plans should be created, promoted and communicated in order to minimise the effects of such crises and support HCWs. By focusing on effective communication and preparedness, including access to relevant protective equipment and providing general support to HCWs, the work environment and patient care could be sustained during a crisis such as the COVID-19 pandemic.

Tidskriftsartikel (refereegranskat)abstract
- Background: Fruits and vegetables are rich in compounds with proposed antioxidant, anti-allergic and anti-inflammatory properties, which could contribute to reduce the prevalence of asthma and allergic diseases. Objective: We investigated the association between asthma, and chronic rhino-sinusitis (CRS) with intake of fruits and vegetables in European adults. Methods: A stratified random sample was drawn from the Global Allergy and Asthma Network of Excellence (GA(2)LEN) screening survey, in which 55,000 adults aged 15-75 answered a questionnaire on respiratory symptoms. Asthma score (derived from self-reported asthma symptoms) and CRS were the outcomes of interest. Dietary intake of 22 subgroups of fruits and vegetables was ascertained using the internationally validated GA(2)LEN Food Frequency Questionnaire. Adjusted associations were examined with negative binomial and multiple regressions. Simes procedure was used to control for multiple testing. Results: A total of 3206 individuals had valid data on asthma and dietary exposures of interest. 22.8% reported having at least 1 asthma symptom (asthma score >= 1), whilst 19.5% had CRS. After adjustment for potential confounders, asthma score was negatively associated with intake of dried fruits (beta-coefficient -2.34;95% confidence interval [CI] -4.09,-0.59), whilst CRS was statistically negatively associated with total intake of fruits (OR 0.73; 95% CI 0.55, 0.97). Conversely, a positive association was observed between asthma score and alliums vegetables (adjusted beta-coefficient 0.23; 95% CI 0.06, 0.40). None of these associations remained statistically significant after controlling for multiple testing. Conclusion and clinical relevance: There was no consistent evidence for an association of asthma or CRS with fruit and vegetable intake in this representative sample of European adults.

Resilience Capability and Capacity in Unexpected Crises: Experiences and Lessons Learned in a Healthcare Organisation during the COVID-19 Pandemic
- 2023
-
Ingår i: Journal of Nursing Management. - 0966-0429 .- 1365-2834.

Tidskriftsartikel (refereegranskat)abstract
- Aim. The current article aims to gain insight into (a) what characterises organisational resilience during an unexpected crisis such as COVID-19 and (b) how organisations respond to developments in their environments. Background. In times of societal crises, such as the COVID-19 pandemic, the resilience of the healthcare organisation is tested. Method. This research is based on a case study in a university hospital and a county hospital in Sweden using surveys with both structured and open answers. Results. The result shows ambiguity and “polarised” experiences, emphasising flexibility vs. structure, clear hierarchical information vs. spaces for peer learning through dialogue, and focus on acute care vs. determination to continue with core operations. Conclusion. The article concludes that the pandemic resulted in paradoxes, tensions, and new experiences in organisational processes and interactions. These create opportunities for learning not only during crises but also for improving nursing management in both acute and planned care. Three relations are important in building organisational resilience in crises: resilience capability, resilience capacity, and sustainable resilience practices. Implications for Nursing Management. Organisational resilience under extraordinary circumstances, such as a pandemic, as well as enhancing the previous literature on nursing management that offer a more individually oriented perspective.

Vasodilation and visceral fat in elderly subjects The Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study
- 2006

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Although obesity has long been recognised as a cardiovascular risk factor, only in recent years has the role of visceral adipose tissue (VAT) been evaluated. In the Prospective Study of the Vasculature in Uppsala Seniors (PIVUS) study, we related VAT and other obesity indices to endothelium-dependent vasodilation in both capacitance and resistance arteries. METHODS AND RESULTS: In this population-based study, 1016 subjects aged 70 were evaluated by the invasive forearm technique with acetylcholine (EDV) and brachial artery ultrasound to assess flow-mediated vasodilation (FMD). Intra-abdominal visceral (VAT) and subcutaneous adipose tissue (SAT) were determined by magnetic resonance imaging in a random sample of 287 subjects. EDV, but not FMD, was inversely related to VAT, SAT, BMI and the waist/hip ratio (r=-0.23, -0.16, -0.21 and -0.11, respectively, p=0.05-0.001 after adjustment for gender). In multiple regression analysis however, only VAT was an independent predictor of EDV. Similar results were obtained for endothelium-independent vasodilation (EIDV, infusion of sodium nitroprusside in the brachial artery). CONCLUSIONS: Both endothelium-dependent and independent vasodilation in the forearm resistance arteries, but not FMD in the brachial artery, was reduced in elderly subjects with increased intra-abdominal adipose tissue mass. This finding suggests deterioration in general vasoreactivity mainly in resistance arteries in elderly subjects with intra-abdominal obesity.
