A realist review to explore how low-income pregnant women use food vouchers from the UK’s Healthy Start programme

Objectives: To explore how low-income pregnant women use Healthy Start food vouchers, the potential impacts of the programme, which women might experience these impacts and why. Design: A realist review. Eligibility criteria for selecting studies: Primary or empirical studies (of any design) were included if they contributed relevant evidence or insights about how low-income women use food vouchers from the Healthy Start (UK) or the Special Supplemental Nutrition Program for Women, Infants and Children (US) programmes. The assessment of ‘relevance’ was deliberately broad to ensure that reviewers remained open to new ideas from a variety of sources of evidence. Analysis: A combination of evidence synthesis and realist analysis techniques was used to modify, refine and substantiate programme theories, which were constructed as explanatory ‘context – mechanism – outcome’ (CMO) configurations. Results: 38 primary studies were included in this review: four studies on Healthy Start and 34 studies on WIC. Two main outcome strands were identified: dietary improvements (intended) and financial assistance (unintended). Three evidence-informed programme theories were proposed to explain how aspects of context (and mechanisms) may generate these outcomes: the ‘relative value’ of healthy eating (prioritisation of resources); retailer discretion (pressure to ‘bend the rules’); the influence of other family members (disempowerment). Conclusions: This realist review suggests that some low-income pregnant women may use Healthy Start vouchers to increase their consumption of fruits and vegetables and plain cow’s milk, whereas others may use them to reduce food expenditure and save money for other things

Characterisation of a novel Emaravirus identified in mosaic‐diseased Eurasian aspen (Populus tremula)

Since Emaraviruses have been discovered in 2007 several new species were detected in a range of host plants. Five genome segments of a novel Emaravirus from mosaic‐diseased Eurasian aspen (Populus tremula) have been completely determined. The monocistronic, segmented ssRNA genome of the virus shows a genome organisation typical for Emaraviruses encoding the viral RNA‐dependent RNA polymerase (RdRP, 268.2 kDa) on RNA1 (7.1 kb), a glycoprotein precursor (GPP, 73.5 kDa) on RNA2 (2.3 kb), the viral nucleocapsid protein (N, 35.6 kDa) on RNA3 (1.6 kb), and a putative movement protein (MP, 41.0 kDa) on RNA4 (1.6 kb). The fifth identified genome segment (RNA5, 1.3 kb) encodes a protein of unknown function (P28, 28.1 kDa). We discovered that it is distantly related to proteins encoded by Emaraviruses, such as P4 of European mountain ash ringspot‐associated virus. All proteins from this group contain a central hydrophobic region with a conserved secondary structure and a hydrophobic amino acid stretch, bordered by two highly conserved positions, thus clearly representing a new group of homologues of Emaraviruses. The virus identified in Eurasian aspen is closely associated with observed leaf symptoms, such as mottle, yellow blotching, variegation and chloroses along veins. All five viral RNAs were regularly detectable by RT‐PCR in mosaic‐diseased P. tremula in Norway, Finland and Sweden (Fennoscandia). Observed symptoms and testing of mosaic‐diseased Eurasian aspen by virus‐specific RT‐PCR targeting RNA3 and RNA4 confirmed a wide geographic distribution of the virus in Fennoscandia. We could demonstrate that the mosaic‐disease is graft‐transmissible and confirmed that the virus is the causal agent by detection in symptomatic, graft‐inoculated seedlings used as rootstocks as well as in the virus‐infected scions used for graft‐inoculation. Owing to these characteristics, the virus represents a novel species within the genus Emaravirus and was tentatively denominated aspen mosaic‐associated virus.Peer Reviewe

Arealrepresentativ overvåking av semi-naturlig eng. Pilot i Nordland og Trøndelag 2019

Denne pilotstudien er gjennomført på oppdrag av Miljødirektoratet. Formålet har vært å teste ut og videreutvikle en overvåkningsmetodikk for semi-naturlig eng som ble publisert av NIBIO i 2017. Det var ønskelig at metodikken for semi-naturlig eng (ASO, Arealrepresentativ overvåkning av seminaturlig eng i Norge) skulle samsvare med og utfylle ANO (Arealrepresentativ naturovervåkning i Norge). Pilotstudien og uttestingen av metodikken ble gjennomført i to observasjonsområder, ett i Nordland (Alstadhaug) og ett i Trøndelag (Stjørdal). I rapporten beskrives det hvilke justeringer og tilpasninger det anbefales å gjøre for å tilpasse ASO til ANO, hvilke deler av metodikken som bør være forskjellig.publishedVersio

The impact of hyperfractionated radiotherapy regimen in patients with non-small cell lung cancer

The prognosis for patients with lung cancer is poor with an average of 5-year overall survival rate of only 10-15 % taking all clinical stages together. The aim of this study was to elucidate the impact of the radiotherapy regimen on survival. Clinical data were collected from all the Swedish Oncology Departments for 1,287 patients with a diagnosed non-small cell lung cancer (NSCLC) subjected to curatively intended irradiation (>= 50 Gy) during the years 1990 to 2000. The included patients were identified based on a manual search of all medical and radiation charts at the oncology departments from which the individual patient data were collected. Patients who did not have a histopathological diagnosis date and/or death date/last follow-up date as well as patients being surgically treated were excluded from the study (n = 592). Thus, 695 patients were included in the present study. Patients who received hyperfractionated radiotherapy (HR) had a higher local control rate compared with patients receiving conventional fractionation (CF) (38 vs. 49 % local relapse). The difference in survival between the two radiotherapy regimens was statistically significant in a univariate Cox analysis (p = 0.023) in favor of HR. This significance was, however, not retained in a multivariate Cox analysis (p = 0.56). Thus, the possible beneficial effects of hyperfractionation are still unclear and need to be further investigated in well-controlled prospective clinical trials, preferably including systemic treatment with novel drugs

Swedish Lung Cancer Radiation Study Group: Predictive value of age at diagnosis for radiotherapy response in patients with non-small cell lung cancer

Introduction. The aim of the present study was to investigate the impact of age at diagnosis on prognosis in patients treated with curatively intended radiotherapy for NSCLC. Material and methods. This is a joint effort among all the Swedish Oncology Departments that includes all identified patients with a diagnosed non-small cell lung cancer that have been subjected to curatively intended irradiation (>= 50 Gy) treated during 1990 to 2000. Included patients had a histopathological/cytological diagnosis date as well as a death date or a last follow-up date. The following variables were studied in relation to overall and disease-specific survival: age, gender, histopathology, time period, smoking status, stage and treatment. Results. The median overall survival of all 1146 included patients was 14.7 months, while the five-year overall survival rate was 9.5%. Younger patients (= 75 years was comparable to those aged <55 years. Conclusion. In this large retrospective study we describe that patients younger than 55 years treated with curatively intended radiotherapy for NSCLC have a better overall survival than patients aged 55-64 and 65-74 years and that younger patients seem to benefit more from the addition of surgery and/or chemotherapy to radiotherapy. Due to the exploratory nature of the study, these results should be confirmed in future prospective trials
