RESUMO
BACKGROUND: One way in which patients can participate in care is by taking part in medical documentation. Producing documentation together with patients has been found to decrease the amount of incorrect information, help patients to be involved, and promote shared decision-making. The aims of this study were to develop and implement a practice of producing documentation together with patients and to examine staff and patient experiences of this practice. METHODS: A quality improvement study was conducted from 2019 to 2021 at a Day Surgery Unit in a Danish University Hospital. Before implementing a practice of documenting together with patients, nurses' perceptions of doing documentation together with patients were examined via a questionnaire survey. After an implementation period, a similar follow-up survey with staff was conducted, together with structured patient phone interviews. RESULTS: A total of 24 nursing staff out of 28 (86%) filled in the questionnaire at baseline and 22 out of 26 (85%) at follow-up. A total of 61 out of 74 invited patients (82%) were interviewed. At baseline, the majority (71-96%) of participants agreed that documentation done together with the patient would contribute to increased patient safety, fewer errors, real-time documentation, patient involvement, visible patient perspective, correction of errors, more accessible information and less duplication of work. At follow-up, significant decreases in the staffs' positive perceptions of the benefits of documenting together with patients were found for all areas except for "real-time documentation" and "less duplication of work". Almost all patients found it okay that the nurses wrote up medical documentation during the interview, and more than 90% of patients found the staff responsive or very responsive and present during the reception interview. CONCLUSION: Before implementation of a practice of documenting together with patients, the majority of staff assessed such documentation as being beneficial, but a significant decrease in positive assessment was found at follow-up, with challenges such as feeling less connected with the patient and practical, IT-related issues being described. The patients found the staff to be present and responsive and felt that it was important to know what was being written in their medical record.
RESUMO
BACKGROUND: Gluten-free (GF) diet during pregnancy ameliorates autoimmune diabetes in nonobese diabetic (NOD) mouse offspring. Due to comorbidity of celiac disease in type 1 diabetes, we hypothesized that GF diet in utero alleviates the humoral and histopathological signs of celiac disease in NOD mice. We aimed to establish the mechanisms behind the diabetes-protective effect of GF diet in utero. METHODS: Breeding pairs of NOD mice were fed a GF or gluten-containing standard (STD) diet until parturition. The offspring were nursed by mothers on STD diet and continued on this diet until ages 4 and 13 weeks. Analyses of serum antitissue transglutaminase (anti-tTG) intestine and islet histology, islet transglutaminase (TG) activity, and cytokine expression in T cells from lymphoid organs were performed. RESULTS: GF versus STD diet in utero led to reduced serum anti-tTG titre and increased villus-to-crypt ratio at both ages. Insulitis along with systemic and local inflammation were decreased, but islet TG activity was unchanged in 13-week-old GF mice. These mice had unchanged beta-cell volumes, but increased islet numbers throughout the prediabetic period. CONCLUSIONS: Collectively, GF diet administered during pregnancy improves signs of celiac disease and autoimmune diabetes in the offspring. The diabetes-ameliorative effect of GF diet in utero is followed by dampening of inflammation, unchanged beta-cell volume, but increased islet numbers.

Although ancient DNA from sediments (sedaDNA) has been used to investigate past ecosystems, the approach has never been directly compared with the traditional methods of pollen and macrofossil analysis. We conducted a comparative survey of 18 ancient permafrost samples spanning the Late Pleistocene (46-12.5 thousand years ago), from the Taymyr Peninsula in northern Siberia. The results show that pollen, macrofossils and sedaDNA are complementary rather than overlapping and, in combination, reveal more detailed information on plant palaeocommunities than can be achieved by each individual approach. SedaDNA and macrofossils share greater overlap in plant identifications than with pollen, suggesting that sedaDNA is local in origin. These two proxies also permit identification to lower taxonomic levels than pollen, enabling investigation into temporal changes in species composition and the determination of indicator species to describe environmental changes. Combining data from all three proxies reveals an area continually dominated by a mosaic vegetation of tundra-steppe, pioneer and wet-indicator plants. Such vegetational stability is unexpected, given the severe climate changes taking place in the Northern Hemisphere during this time, with changes in average annual temperatures of >22 °C. This may explain the abundance of ice-age mammals such as horse and bison in Taymyr Peninsula during the Pleistocene and why it acted as a refugium for the last mainland woolly mammoth. Our finding reveals the benefits of combining sedaDNA, pollen and macrofossil for palaeovegetational reconstruction and adds to the increasing evidence suggesting large areas of the Northern Hemisphere remained ecologically stable during the Late Pleistocene.

Nunataks are isolated bedrocks protruding through ice sheets. They vary in age, but represent island environments in 'oceans' of ice through which organism dispersals and replacements can be studied over time. The J.A.D. Jensen's Nunataks at the southern Greenland ice sheet are the most isolated nunataks on the northern hemisphere - some 30 km from the nearest biological source. They constitute around 2 km(2) of ice-free land that was established in the early Holocene. We have investigated the changes in plant composition at these nunataks using both the results of surveys of the flora over the last 130 years and through reconstruction of the vegetation from the end of the Holocene Thermal Maximum (5528 ± 75 cal year BP) using meta-barcoding of plant DNA recovered from the nunatak sediments (sedaDNA). Our results show that several of the plant species detected with sedaDNA are described from earlier vegetation surveys on the nunataks (in 1878, 1967 and 2009). In 1967, a much higher biodiversity was detected than from any other of the studied periods. While this may be related to differences in sampling efforts for the oldest period, it is not the case when comparing the 1967 and 2009 levels where the botanical survey was exhaustive. As no animals and humans are found on the nunataks, this change in diversity over a period of just 42 years must relate to environmental changes probably being climate-driven. This suggests that even the flora of fairly small and isolated ice-free areas reacts quickly to a changing climate.

PREMISE OF THE STUDY: The Asparagales, with ca. 40% of all monocotyledons, include a host of commercially important ornamentals in families such as Orchidaceae, Alliaceae, and Iridaceae, and several important crop species in genera such as Allium, Aloe, Asparagus, Crocus, and Vanilla. Though the order is well defined, the number of recognized families, their circumscription, and relationships are somewhat controversial. METHODS: Phylogenetic analyses of Asparagales were based on parsimony and maximum likelihood using nucleotide sequence variation in three plastid genes (matK, ndhF, and rbcL) and two mitochondrial genes (atp1 and cob). Branch support was assessed using both jackknife analysis implementing strict-consensus (SC) and bootstrap analysis implementing frequency-within-replicates (FWR). The contribution of edited sites in the mitochondrial genes to topology and branch support was investigated. KEY RESULTS: The topologies recovered largely agree with previous results, though some clades remain poorly resolved (e.g., Ruscaceae). When the edited sites were included in the analysis, the plastid and mitochondrial genes were highly incongruent. However, when the edited sites were removed, the two partitions became congruent. CONCLUSIONS: Some deeper nodes in the Asparagales tree remain poorly resolved or unresolved as do the relationships of certain monogeneric families (e.g., Aphyllanthaceae, Ixioliriaceae, Doryanthaceae), whereas support for many families increases. However, the increased support is dominated by plastid data, and the potential influence of mitochondrial and biparentially inherited single or low-copy nuclear genes should be investigated.

Laboratory mice (Mus musculus) are typically housed in simple cages consisting of one open space. These standard cages may thwart mouse ability to segregate resting areas from areas where they eliminate, a behaviour that is prevalent across the animal kingdom. No scientific work has directly tested whether mice engage in such segregation behaviour, or whether the ability to do so may have welfare consequences. Here we show that mice, whether housed in standard cages or a complex housing system consisting of three interconnected standard cages, kept nesting and elimination sites highly segregated, with nest and urine co-occurring in the same location only 2% of the time. However, mice in the complex system established these clean and dirty sites in separate cages instead of separate locations within one cage, and carried bedding materials (cellulose pellets) from their nesting cages to their latrine cage. Moreover, mice in the complex system displayed more behaviours associated with positive welfare and were less disturbed by weekly husbandry procedures. We conclude that mice find waste products aversive, and that housing mice in a way that facilitates spatial segregation provides a simple way of allowing the expression of natural behaviours and improving welfare.

According to many national recommendations, women should be physically active during pregnancy, but empirical evidence to support this recommendation is sparse. The authors' aim in this study was to examine the relation between physical exercise during pregnancy and the risk of preterm birth. Self-reported data on physical exercise during pregnancy were collected prospectively for 87,232 singleton pregnancies included in the Danish National Birth Cohort between 1996 and 2002. Hazard ratios for preterm birth according to hours of exercise per week, type of exercise, and metabolic equivalent-hours per week, respectively, were calculated using Cox regression analysis. Results showed a reduced risk of preterm birth among the almost 40% of women who engaged in some kind of exercise during pregnancy in comparison with nonexercisers (hazard ratio = 0.82, 95% confidence interval: 0.76, 0.88), but no dose-response relation was seen. The association was not affected by the type of exercise, and the results were not altered when the degree of preterm birth was taken into account. These findings do not indicate any adverse effects of exercise on the risk of preterm birth and therefore do not contradict current recommendations.

Intrauterine exposure to artificial sex hormones such as oral contraceptives may be associated with an increased risk of fetal death. Between 1996 and 2002, a total of 92 719 women were recruited to The Danish National Birth Cohort and interviewed about exposures during pregnancy. Outcome of pregnancy was identified through linkage to the Civil Registration System and the National Discharge Registry. The authors analysed the risk of fetal death after recruitment to the cohort by using proportional hazards regression models with gestational age as the underlying time scale. In total, 1102 (1.2%) women took oral contraceptives during pregnancy. Use of combined oestrogen and progesterone oral contraceptives (COC) or progesterone-only oral contraceptives (POC) during pregnancy was not associated with increased hazard ratios of fetal death compared with non-users, HR 1.01 [95% CI 0.71, 1.45] and HR 1.37 [95% CI 0.65, 2.89] respectively. Neither use of COC nor POC prior to pregnancy was associated with fetal death. Stratification by maternal age and smoking showed elevated risks of fetal death for women <30 years and smokers using oral contraception during pregnancy, but the interactions were not significant. In conclusion, there was no evidence that oral contraceptive use before or during pregnancy is associated with an increased risk of fetal death.

Metabarcoding of lake sediments have been shown to reveal current and past biodiversity, but little is known about the degree to which taxa growing in the vegetation are represented in environmental DNA (eDNA) records. We analysed composition of lake and catchment vegetation and vascular plant eDNA at 11 lakes in northern Norway. Out of 489 records of taxa growing within 2 m from the lake shore, 17-49% (mean 31%) of the identifiable taxa recorded were detected with eDNA. Of the 217 eDNA records of 47 plant taxa in the 11 lakes, 73% and 12% matched taxa recorded in vegetation surveys within 2 m and up to about 50 m away from the lakeshore, respectively, whereas 16% were not recorded in the vegetation surveys of the same lake. The latter include taxa likely overlooked in the vegetation surveys or growing outside the survey area. The percentages detected were 61, 47, 25, and 15 for dominant, common, scattered, and rare taxa, respectively. Similar numbers for aquatic plants were 88, 88, 33 and 62%, respectively. Detection rate and taxonomic resolution varied among plant families and functional groups with good detection of e.g. Ericaceae, Roseaceae, deciduous trees, ferns, club mosses and aquatics. The representation of terrestrial taxa in eDNA depends on both their distance from the sampling site and their abundance and is sufficient for recording vegetation types. For aquatic vegetation, eDNA may be comparable with, or even superior to, in-lake vegetation surveys and may therefore be used as an tool for biomonitoring. For reconstruction of terrestrial vegetation, technical improvements and more intensive sampling is needed to detect a higher proportion of rare taxa although DNA of some taxa may never reach the lake sediments due to taphonomical constrains. Nevertheless, eDNA performs similar to conventional methods of pollen and macrofossil analyses and may therefore be an important tool for reconstruction of past vegetation.

Elevated levels of the cytokine TL1A is associated with several autoimmune diseases e.g. rheumatoid arthritis and inflammatory bowel disease. However, the exact role of TL1A remains elusive. In this study, we investigated the function of TL1A in a pro-inflammatory setting. We show that TL1A together with IL-12, IL-15 and IL-18 increases expression of the co-stimulatory molecules CD154 (CD40 ligand) and CD134 (OX40) on previously activated CD4+ T cells. This indicates that TL1A functions as a co-stimulatory molecule, decreasing the activation threshold of T-cells. We have previously shown that TL1A co-stimulation strongly induces IL-6 in human healthy leukocytes. Interestingly, the cytokine-activated effector T-cells did not produce IL-6 in response to TL1A, indicating distinct effects of TL1A on different cell populations. We further show that this co-stimulation increases the expression of CD25 (IL-2Rα) and CD11a (α-chain of LFA-1) on CD4 T-cells, likely governing increased IL-2/IL-15 sensitivity and cell-cell contact. Along with this, TL1A co-stimulation caused a specific induction of IL-22 and GM-CSF from the activated T-cells. These results substantially contribute to the explanation of TL1A's role in inflammation. Our results suggest that TL1A should be considered as a target for immunotherapeutic treatment of rheumatoid arthritis and inflammatory bowel disease.

An elevated level of the cytokine TL1A is known to be associated with several autoimmune diseases, e.g. rheumatoid arthritis and inflammatory bowel disease. However, the mode of action of TL1A remains elusive. In this study, we investigated the role of TL1A in a pro-inflammatory setting, using human leukocytes purified from healthy donors. We show that TL1A, together with IL-12, IL-15 and IL-18, directly induces the production of IL-6 and TNF-α from leukocytes. Interestingly, TL1A-induced IL-6 was not produced by CD14⺠monocytes. We further show that the produced IL-6 is fully functional, as measured by its ability to signal through the IL-6 receptor, and that the induction of IL-6 is independent of TCR stimulation. Furthermore, the transcription factor PLZF was induced in stimulated cells. These results offer a substantial explanation for the role of TL1A, since TNF-α and IL-6 are directly responsible for much of the inflammatory state in many autoimmune diseases. Our study suggests that TL1A is a possible target for the treatment of autoimmune diseases.

PREMISE OF THE STUDY: Microsatellite primers were developed for Eucalyptus victrix (Myrtaceae) to evaluate the population and spatial genetic structure of this widespread northwestern Australian riparian tree species, which may be impacted by hydrological changes associated with mining activity. ⢠METHODS AND RESULTS: 454 GS-FLX shotgun sequencing was used to obtain 1895 sequences containing putative microsatellite motifs. Ten polymorphic microsatellite loci were identified and screened for variation in individuals from two populations in the Pilbara region. Observed heterozygosities ranged from 0.44 to 0.91 (mean: 0.66) and the number of alleles per locus ranged from five to 25 (average: 11). ⢠CONCLUSIONS: These microsatellite loci will be useful in future studies of population and spatial genetic structure in E. victrix, and inform the development of seed sourcing strategies for the species.
RESUMO
The characterization of biomolecules from ancient samples can shed otherwise unobtainable insights into the past. Despite the fundamental role of transcriptomal change in evolution, the potential of ancient RNA remains unexploited - perhaps due to dogma associated with the fragility of RNA. We hypothesize that seeds offer a plausible refuge for long-term RNA survival, due to the fundamental role of RNA during seed germination. Using RNA-Seq on cDNA synthesized from nucleic acid extracts, we validate this hypothesis through demonstration of partial transcriptomal recovery from two sources of ancient maize kernels. The results suggest that ancient seed transcriptomics may offer a powerful new tool with which to study plant domestication.

It is commonly believed that trees were absent in Scandinavia during the last glaciation and first recolonized the Scandinavian Peninsula with the retreat of its ice sheet some 9000 years ago. Here, we show the presence of a rare mitochondrial DNA haplotype of spruce that appears unique to Scandinavia and with its highest frequency to the west-an area believed to sustain ice-free refugia during most of the last ice age. We further show the survival of DNA from this haplotype in lake sediments and pollen of Trøndelag in central Norway dating back ~10,300 years and chloroplast DNA of pine and spruce in lake sediments adjacent to the ice-free Andøya refugium in northwestern Norway as early as ~22,000 and 17,700 years ago, respectively. Our findings imply that conifer trees survived in ice-free refugia of Scandinavia during the last glaciation, challenging current views on survival and spread of trees as a response to climate changes.

AIMS: Transient elastography (TE) is a non-invasive sensitive tool for diagnosing cirrhosis in hospital-based cohorts. This study aimed to evaluate TE as a screening tool for cirrhosis among drug users. DESIGN: Cross-sectional study. SETTING: All treatment centres in the county of Funen, Denmark. PARTICIPANTS: Drug users attending treatment centres during the presence of the study team. MEASUREMENTS: Liver stiffness measurements (LSM) by transient elastography using the Fibroscan device; blood tests for viral hepatitis, HIV infection and hyaluronic acid (HA) levels; and routine liver tests. Individuals with LSM ≥ 8 kPa were referred to the hospital for treatment evaluation. Individuals with LSM ≥ 12 kPa were recommended a liver biopsy. FINDINGS: Among 175 drug users negative for hepatitis C, 13% had LSM = 8-11.9 kPa and 4% had LSM ≥ 12 kPa; elevated LSM was associated with a body mass index (BMI) > 30. Among 128 drug users with chronic hepatitis C, 19.5% had LSM = 8-11.9 kPa and 21.1% had LSM ≥ 12 kPa (P < 0.001). Repeat LSM at liver biopsy performed a median 3 months after screening showed a significant decrease (<12 kPa) among 30% (six of 20), and this was independent of alcohol consumption, BMI, age and gender. In 29 patients where liver biopsy was performed a LSM ≥ 16 kPa predicted cirrhosis with 88.9% sensitivity and 90% specificity. CONCLUSIONS: Transient elastography is a feasible screening tool for cirrhosis among drug users. Transient elastography identifies severe liver fibrosis in a significant proportion of drug users with hepatitis C infections but management should not be based on a single elevated liver stiffness measurement.

AIM: The aim of this study is to review the epidemiological literature from the past 27 years on social inequality in fetal and perinatal mortality in the Nordic countries in order to examine whether social inequalities in fetal and perinatal mortality exist, and whether there are differences between the countries. METHODS: The databases MEDLINE and EMBASE were searched for Nordic epidemiological studies published between January 1980 and August 2007 about the association between social indicators and the outcomes spontaneous abortion, stillbirth or perinatal mortality. Thirty-five studies that fulfilled the inclusion criteria were identified for this review. RESULTS: Social differences in stillbirth and perinatal mortality were found in all of the identified Finnish and Norwegian studies and in the majority of studies from Denmark, whereas in the Swedish studies the findings were less consistent. As only a small number of studies on spontaneous abortion were identified (n=3), no conclusions were drawn with regard to this outcome. CONCLUSIONS: There seems to be a reasonable body of evidence that social inequality in stillbirth and perinatal mortality exists in Norway, Finland and Denmark, whereas the conclusions regarding Sweden are more uncertain. A number of methodological problems complicate the comparison of the findings. Nordic collaborative analyses of social gradients in spontaneous abortion, stillbirth and perinatal mortality, which take these methodological concerns into account, are needed in order to draw inferences across countries.

We investigated the association between exercise during pregnancy and risk of miscarriage among more than 90,000 pregnant women. Information on exposures was obtained by means of computer-assisted telephone interviews. A relation was found between the amount of exercise and the risk of miscarriage with the risk of miscarriage rising stepwise by the amount of exercise performed. Particularly "high impact exercise" was associated with an increased risk of miscarriage. No association was seen between exercise and risk of miscarriage after 18 weeks of gestation.
RESUMO
An important issue regarding treatment for alcohol abuse is the high rate of relapse following treatment. In the research on treatment of alcohol abuse, the concept of coping has been proposed as a relevant factor in the relationship between relapse crises and treatment outcome. The present study investigated the role of pretreatment coping strategies in outcome of outpatient treatment for alcohol abuse. The pretreatment coping strategies of 136 clients receiving outpatient treatment for alcohol abuse were examined as a predictor of drinking pattern after treatment. The pretreatment coping strategies were assessed by the COPE questionnaire. Drinking pattern after treatment was assessed at follow-up one year after treatment was entered. Results indicated that some pretreatment coping strategies are identifiable as adaptive and maladaptive coping strategies, respectively, regarding successful treatment for alcohol abuse. Restraint coping was found predictive of a positive drinking pattern at follow-up while the use of alcohol to cope was found predictive of a negative drinking pattern. Furthermore, the results showed tendencies towards the possibility that some coping strategies co-operated differently with types of treatment methods.
