Navigating healthcare systems: A qualitative study on socially marginalised patients' experiences of hospital transition and support by social nurses.

BACKGROUND: Socially marginalised patients face many challenges related to their health condition and often have several contacts with healthcare and social service workers. The Danish social nursing initiative, whose nurses have experience and knowledge about marginalisation, aims to support socially marginalised patients during hospital admission and through hospital transitions. However, there is limited knowledge about the hospital transitions of patients being supported by a social nurse. OBJECTIVES: The objectives of this study were to explore (1) the perspectives of socially marginalised patients on the transition from hospital to home and (2) how these patients experience the importance of social nursing on patient trajectories after hospital discharge. METHODS: A qualitative study with a phenomenological and hermeneutic approach was performed at a large hospital in southern Denmark. Adult patients who had contact with a social nurse during hospital admission were purposely sampled. Data were collected between January 2023 and March 2023. Initial patient interviews were conducted during hospital admission with a second interview 7-22 days after discharge. Systematic text condensation was used for the analysis, and Nvivo 12 supported data storage and coding. ETHICAL APPROVAL: The study is registered with the Danish Data Protection Agency (22/47509). Informed consent was given by the participants. RESULTS: Sixteen patients participated in the study. The participants experienced major challenges in their transitions from the hospital, which were generally related to their interactions with many different social and healthcare services. While the social nurses supported the patients and helped facilitate care during hospital admission and after discharge, the participants identified transitional care gaps related to multidisciplinary cooperation and standardised care options. CONCLUSIONS: This study identifies challenges related to the hospital transition of socially marginalised patients, which indicates a gap in healthcare services. Future research should focus on improving interprofessional collaboration with socially marginalised patients across healthcare services.

The effectiveness of pollen allergen immunotherapy on allergic rhinitis over 18 years: A national cohort study in Denmark.

BACKGROUND: Because long-term effectiveness of pollen allergen immune therapy (AIT) for allergic rhinitis (AR) is not well-described, we studied effectiveness over 18 years in Denmark. METHODS: A register-based cohort study using data on filled prescriptions, 1995-2016, Denmark. In a cohort of 1.1 million intranasal corticosteroid inhaler users (proxy for AR), we matched users treated with grass, birch or mugwort AIT 1:2 with non-treated users on baseline year and 24 characteristics in the 3 years prior to baseline. The primary outcome was the odds ratio (OR) of using anti-allergic nasal inhaler during the pollen season in the treated versus non-treated group by years since baseline. RESULTS: Among 7760 AR patients treated with pollen AIT, the OR of using nasal inhaler 0-5 years after baseline was reduced when compared with 15,520 non-treated AR individuals (0-2 years, OR 0.84 (0.81-0.88); 3-5 years, OR 0.88 (0.84-0.92)), but was close to unity or higher thereafter (6-9 years, OR 1.03 (0.97-1.08); 10-18 years, OR 1.18 (1.11-1.26)). In post hoc analyses, results were more consistent for those who already had 3 of 3 baseline years of use, and in patients using nasal inhaler in the latest pollen season (0-2 years, OR 0.76 (0.72-0.79); 3-5 years OR 0.86 (0.81-0.93); 6-9 years, OR 0.94 (0.87-1.02); 10-18 years, OR 0.94 (0.86-1.04)) as opposed to no such use. CONCLUSIONS: Patients treated with pollen AIT in routine care to a higher degree stopped using anti-allergic nasal inhaler 0-5 years after starting the standard 3 years of therapy, and not beyond 5 years. Post hoc analyses suggested effectiveness was more consistent among patients with persistent AR.

Trends in the use of complementary and alternative medicine between 1987 and 2021 in Denmark.

BACKGROUND: Complementary and alternative medicine (CAM) has been widely and increasingly used worldwide during the past decades. Nevertheless, studies in long-term trends of CAM use are limited. The aim of this study was to assess long-term trends in the prevalence of CAM use (both overall and for specific CAMs) between 1987 and 2021 in the adult Danish population and to examine certain sociodemographic characteristics of CAM users. METHODS: Data derived from nationally representative health surveys in the general adult population (≥ 16 years) in Denmark (the Danish Health and Morbidity Surveys) conducted in 1987, 1994, 2000, 2005, 2010, 2013, 2017, and 2021. The response proportion declined from 79.9% in 1987 to 45.4% in 2021. CAM use was assessed by questions on ever use of specific types of CAMs and overall use within the past 12 months. Differences in use of CAMs across educational levels were assessed using the Slope Index of Inequality (SII). RESULTS: An overall increase in the prevalence of CAM use within the past 12 months was found between 1987 (10.0%) and 2021 (24.0%). However, a stagnation was observed between 2010 and 2017, after which the prevalence decreased in 2021. In all survey waves, the prevalence was higher among women than men. For both sexes, the prevalence tended to be highest among respondents aged 25-44 years and 45-64 years. The group with 13-14 years of education had the highest prevalence of CAM use compared to the other educational groups (< 10 years, 10-12 years, and ≥ 15 years). SII values for both men and women increased between 1987 and 2021, which indicates an increase in differences of CAM use across educational groups. In all survey waves the most frequently used CAMs included massage and other manipulative therapies, acupuncture, and reflexology. CONCLUSIONS: The use of CAM has increased markedly within the last decades and recently stagnated at high levels, which underlines the importance of securing high quality information and education for the public, health professionals, and legislators to ensure and promote safe use of CAMs.

100 ancient genomes show repeated population turnovers in Neolithic Denmark.

Major migration events in Holocene Eurasia have been characterized genetically at broad regional scales1-4. However, insights into the population dynamics in the contact zones are hampered by a lack of ancient genomic data sampled at high spatiotemporal resolution5-7. Here, to address this, we analysed shotgun-sequenced genomes from 100 skeletons spanning 7,300 years of the Mesolithic period, Neolithic period and Early Bronze Age in Denmark and integrated these with proxies for diet (13C and 15N content), mobility (87Sr/86Sr ratio) and vegetation cover (pollen). We observe that Danish Mesolithic individuals of the Maglemose, Kongemose and Ertebølle cultures form a distinct genetic cluster related to other Western European hunter-gatherers. Despite shifts in material culture they displayed genetic homogeneity from around 10,500 to 5,900 calibrated years before present, when Neolithic farmers with Anatolian-derived ancestry arrived. Although the Neolithic transition was delayed by more than a millennium relative to Central Europe, it was very abrupt and resulted in a population turnover with limited genetic contribution from local hunter-gatherers. The succeeding Neolithic population, associated with the Funnel Beaker culture, persisted for only about 1,000 years before immigrants with eastern Steppe-derived ancestry arrived. This second and equally rapid population replacement gave rise to the Single Grave culture with an ancestry profile more similar to present-day Danes. In our multiproxy dataset, these major demographic events are manifested as parallel shifts in genotype, phenotype, diet and land use.

Adherence to different forms of plant-based diets and pregnancy outcomes in the Danish National Birth Cohort: A prospective observational study.

INTRODUCTION: The number of people adhering to plant-based diets has been increasing dramatically in recent years, fueled by both environmental and animal welfare concerns. Beneficial or possible adverse consequences of such diets, particularly the most restrictive forms during pregnancy, have been minimally explored. The aim of this prospective observational study was to examine associations between different forms of plant-based diets during pregnancy with birth outcomes and pregnancy complications. MATERIAL AND METHODS: The Danish National Birth Cohort included 100 413 pregnancies to 91 381 women in 1996-2002. The population consisted of 66 738 pregnancies, about which sufficient dietary data were available and included in the study. Dietary and supplemental intake was assessed by Food Frequency Questionnaire in gestational week 25 and women were characterized as fish/poultry-vegetarians, lacto/ovo-vegetarians, vegans or omnivorous, based on their self-report in gestational week 30. Main outcome measures were pregnancy and birth complications, birthweight and small for gestational age. RESULTS: A total of 98.7% (n = 65 872) of participants were defined as omnivorous, whereas 1.0% (n = 666), 0.3% (n = 183) and 0.03% (n = 18) identified themselves as fish/poultry vegetarians, lacto/ovo-vegetarians or vegans, respectively. Protein intake was lower among lacto/ovo-vegetarians (13.3%) and vegans (10.4%) than among omnivorous participants (15.4%). Intake of micronutrients was also considerably lower among vegans, but when dietary supplements were taken into consideration, no major differences were observed. Compared with omnivorous mothers, vegans had a higher prevalence of preeclampsia and their offspring had on average -240 g (95% confidence interval -450 to -30) lower birthweight. CONCLUSIONS: The women reporting that they adhered to vegan diets during pregnancy had offspring with lower mean birthweight and higher risk of preeclampsia compared with omnivorous mothers. Low protein intake might be one plausible explanation for the observed association with birthweight.

Tobacco Exposure and Efficacy of Biologic Therapy in Patients With Severe Asthma: A Nationwide Study From the Danish Severe Asthma Register.

BACKGROUND: Randomized trials of biologics in severe, uncontrolled asthma have excluded patients with a cumulative tobacco exposure of more than 10 pack-years. Therefore, our knowledge of the impact of smoking exposure on the clinical effects of biologics in severe asthma remains incomplete. However, because many patients with asthma are current or former smokers, investigating the potential impacts of tobacco exposure on the effects of biologic treatment is clinically important. OBJECTIVE: To investigate the impact of smoking history and tobacco exposure on the effectiveness of biologic therapy in real-life patients with severe asthma. METHODS: We used data from a complete nationwide cohort of patients with severe asthma who were receiving biologics, the Danish Severe Asthma Register. We divided patients according to smoking history and cumulative tobacco exposure and analyzed data at baseline and after 12 months of biologic treatment. RESULTS: A total of 724 bio-naive patients were identified in the Danish Severe Asthma Register, 398 of whom had never been smokers (55%), 316 were previous smokers (44%), and 10 were current smokers (1%). Within the group of current and former smokers, 37% had 1 to 9 pack-years of tobacco exposure, 26% had 10 to 19 pack-years, and 37% had 20 or more pack-years of tobacco exposure. Patients with tobacco exposure had similar reductions in the number of exacerbations, reductions in maintenance oral corticosteroid use, and improvements in asthma symptoms compared with patients with 0 pack-years. CONCLUSION: Former smoking history and lifetime tobacco exposure do not have an impact on the efficacy of biologics in patients with severe asthma.

Sociodemographic and hospital characteristics for patients with severe functional disorder receiving specialized treatment at hospital. A regional register-based cross-sectional study from Denmark.

OBJECTIVE: 10% of all adult Danish citizen has a functional disorder (FD). This study aimed to describe how patients referred to specialized treatment (CFD; Clinic for Functional Disorders) differentiate from those not referred to specialized treatment in terms of sex, comorbidty, different types of hospital contacts and affiliation to labour market 12 and 60 months prior discharged from the hospital with a FD-diagnosis between 2019 and 2021. METHODS: The study was a register-based cross-sectional study of patients discharged with a FD in North Denmark Region between 2019 and 2021 (study period). Patients between 18 and 65 years of age with FD were identified in the regional patient administrative system. RESULTS: A total of 6831 patients were discharged from the hospital with a FD, of which 160 were referred to CFD. Patients with FD were more likely to be referred to CFD, if they were female, had reduced or no affiliation to the labour market or most hospital contacts were as outpatient. Moreover, an increase in hospital contacts as outpatient and a reduction in affiliation to labour market over time increased the chance of being treated at CFD. CONCLUSION: Patients referred to CFD differed from patients not referred to CFD. Patients referred to CFD were to a lesser extent affiliated to the labour market but had more often hospital contacts as outpatient prior to being discharged with FD. In addition, patients referred to CFD increased their contacts to the hospital as outpatient more than those not referred during the preceding 5 years from discharge with FD.

The effect of clinical guidelines on the utilisation of radiographs in chiropractic clinics in Denmark - an interrupted time series analysis.

BACKGROUND: In Denmark, chiropractors have a statutory right to use radiography and the government-funded national Health Insurance provides partial reimbursement. Danish National Clinical Guidelines recommends against routine use of imaging for uncomplicated spinal pain; however, it is not clear if clinical imaging guidelines recommendations have had an effect on the utilisation of spinal radiography. This study aimed to describe the utilisation rate of radiographs in Danish chiropractic clinics in the period from 2010 to 2020 and to assess the impact of clinical guidelines and policy changes on the utilisation of radiographs in Danish chiropractic clinics. METHODS: Anonymised data from January 1st, 2010, to December 31st, 2020, were extracted from the Danish Regions register on health contacts in primary care. Data consisted of the total number of patients consulting one of 254 chiropractic clinics and the total number of patients having or being referred for radiography. Data were used to investigate the radiography utilisation per month from 2010 to 2020. An 'interrupted time series' analysis was conducted to determine if two interventions, the dissemination of 1) Danish clinical imaging guidelines recommendations and policy changes related to referral for advanced imaging for chiropractors in 2013 and 2) four Danish clinical guidelines recommendations in 2016, were associated with an immediate change in the level and/or slope of radiography utilisation. RESULTS: In total, 336,128 unique patients consulted a chiropractor in 2010 of which 55,449 (15.4%) had radiography. In 2020, the number of patients consulting a chiropractor had increased to 366,732 of which 29,244 (8.0%) had radiography. The pre-intervention utilisation decreased by two radiographs per 10,000 patients per month. Little absolute change, but still statistically significant for Intervention 1, in the utilisation was found after the dissemination of the clinical guidelines and policy changes in 2013 or 2016. CONCLUSIONS: The proportion of Danish chiropractic patients undergoing radiography was halved in the period from 2010 to 2020. However, the dissemination of clinical imaging guidelines recommendations and policy changes related to referrals for advanced imaging showed little meaningful change in the monthly utilisation of radiographs in the same period.

Use of sugar in coffee and tea and long-term risk of mortality in older adult Danish men: 32 years of follow-up from a prospective cohort study.

BACKGROUND: Tea and coffee are the most consumed beverages worldwide and very often sweetened with sugar. However, the association between the use of sugar in tea or coffee and adverse events is currently unclear. OBJECTIVES: To investigate the association between the addition of sugar to coffee or tea, and the risk of all-cause mortality, cardiovascular mortality, cancer mortality and incident diabetes mellitus. METHODS: Participants from the prospective Copenhagen Male Study, included from 1985 to 1986, without cardiovascular disease, cancer or diabetes mellitus at inclusion, who reported regular coffee or tea consumption were included. Self-reported number of cups of coffee and tea and use of sugar were derived from the study questionnaires. Quantity of sugar use was not reported. Primary outcome was all-cause mortality and secondary endpoints were cardiovascular mortality, cancer mortality and incident diabetes mellitus, all assessed through the Danish national registries. The association between adding sugar and all-cause mortality was analyzed by Cox regression analysis. Age, smoking status, daily alcohol intake, systolic blood pressure, body mass index, number of cups of coffee and/or tea consumed per day and socioeconomic status were included as covariates. Vital status of patients up and until 22.03.2017 was assessed. Sugar could be added to either coffee, tea or both. RESULTS: In total, 2923 men (mean age at inclusion: 63±5 years) were included, of which 1007 (34.5%) added sugar. In 32 years of follow-up, 2581 participants (88.3%) died, 1677 in the non-sugar group (87.5%) versus 904 in the sugar group (89.9%). Hazard ratio of the sugar group compared to the non-sugar group was 1.06 (95% CI 0.98;1.16) for all-cause mortality. An interaction term between number of cups of coffee and/or tea per day and adding sugar was 0.99 (0.96;1.01). A subgroup analysis of coffee-only drinkers showed a hazard ratio of 1.11 (0.99;1.26). The interaction term was 0.98 (0.94;1.02). Hazard ratios for the sugar group compared to the non-sugar group were 1.11 (95% CI 0.97;1.26) for cardiovascular disease mortality, 1.01 (95% CI 0.87;1.17) for cancer mortality and 1.04 (95% CI 0.79;1.36) for incident diabetes mellitus. CONCLUSION: In the present population of Danish men, use of sugar in tea and/or coffee was not significantly associated with increased risk of mortality or incident diabetes.

The effect of an adapted Mindfulness-Based Stress Reduction program on mental health, maternal bonding and birth outcomes in psychosocially vulnerable pregnant women: a study protocol for a randomized controlled trial in a Danish hospital-based outpatient setting.

BACKGROUND: Stress and mental disorders in pregnancy can adversely affect the developing fetus. Women with a preconception history of mental disorders or of psychosocial vulnerabilities are at increased risk of experiencing perinatal stress or mental health problems. Mindfulness-Based-Stress-Reduction (MBSR) is an acceptable intervention for pregnant women and has a growing evidence-base with meta-analyses consistently pointing to reductions in symptoms of stress, anxiety and depression. This study protocol aim to address the need for a wider array of evidence-based and non-pharmacological options during pregnancy to reduce stress and improve mental health in a psychosocially highly vulnerable group of women. METHODS: Pregnant women with a preconception history of mental disorders or psychosocial vulnerabilities (n = 240) will be recruited from an obstetric ambulatory clinic at Copenhagen University Hospital, Hvidovre, Denmark. Recruitment for the study began in March 2022 and will continue until the desired number of participants is reached. Consenting pregnant women will be randomized to one of two study arms, an adapted MBSR program as add on to usual care or usual care alone. The primary outcome is mental wellbeing at nine months post-randomization. Secondary and exploratory outcomes include stress, anxiety, depression, and maternal antenatal attachment, experience of childbirth, delivery and mode of delivery. Mindfulness and self-compassion are examined as possible mediators of the effect on outcomes. DISCUSSION: Teaching the skills of mindfulness meditation to a psychosocially vulnerable group of pregnant women could prove a viable and non-pharmacological approach to improve mental health and wellbeing during pregnancy, reduce stress and support the transition to parenthood. Mindfulness-Based Stress Reduction does not target a particular group, and results from the study is thus of potential relevance for pregnant women in general as a means of reducing stress and improving perinatal mental health and wellbeing. TRIAL REGISTRATION: ClinicalTrials.gov: NCT05300646 . Registered March 29, 2022.

Integrated care in a Beveridge system: experiences from England and Denmark.

Health systems internationally face demands to deliver care that is better coordinated and integrated. The health system financing and delivery model may go some, but not all the way in explaining health system fragmentation. In this paper, we consider the road to care integration in two countries with Beveridge style health systems, England and Denmark, that are both ranked as highly Integrated systems in Toth's health integration index. We use the SELFIE framework to compare the policies and reforms that have affected care integration over the past 30 years in the two countries. The countries both started their reform path by reforming to introduce choice and competition, but did so in different ways that set them on different pathways. Nevertheless, after two decades, the countries ended the period with largely similar structures that emphasised the creation of a cross-sectoral governance structure. In the relatively centralised England, by introducing decentralised Integrated Care Systems, and in the relatively decentralised Denmark with a centralising element in the form of new Health Clusters.

Health perspectives and handling of PFAS contamination in Denmark.

Per- and polyfluorinated alkyl substances (PFAS) are a group of man-made extremely persistent chemicals that have been spread worldwide since the 1950s due to their properties as effective water- and grease-repellent and heat- and temperature-resistant. They are associated with an increasing number of health effects including immune and hormonal disturbances and some types of cancer. We present a review of PFAS pollution in Denmark, the current human exposure, suspected health effects, and patient management in environmental medicine.

Barriers and facilitators for sustainable weight loss in the pre-conception period among Danish women with overweight or obesity - a qualitative study.

BACKGROUND: The prevalence of overweight or obesity in women of reproductive age continues to increase. A high pre-pregnancy body mass index (BMI) has been shown to increase the risk of pregnancy complications and predispose offspring to childhood obesity. However, little is known about factors affecting women's ability to achieve sustainable weight management and very few studies have applied behavior change theory to qualitative data. AIM: This study aimed to explore barriers and facilitators for weight management among women with overweight or obesity, who wanted to lose weight before pregnancy. METHODS: We conducted semi-structured interviews with 17 women with a BMI ≥ 27 kg/m2, who planned to become pregnant in the near future. Data were analyzed using an abductive approach and the Capability, Opportunity, Motivation, and Behavior model was applied as a conceptual framework. RESULTS: The women's strongest motivator for pre-conception weight loss was their ability to become pregnant. Barriers to successful weight management included their partners' unhealthy behaviors, mental health challenges, competing priorities, and internalized weight stigmatization. The women described careful planning, partners' health behaviors, social support, and good mental health as facilitators for sustainable weight management. CONCLUSION: Our study provides insights into factors affecting weight management among women with overweight or obesity in the pre-conception period. Future interventions on weight management require a holistic approach, including a focus on social support, especially from the partner, and mental health, as well as an effort to limit internalized weight stigma.

Principles for Just Prioritization of Expensive Biological Therapies in the Danish Healthcare System.

The Danish healthcare system must meet the need for easy and equal access to healthcare for every citizen. However, investigations have shown unfair prioritization of cancer patients and unfair prioritization of resources for expensive medicines over care. What is needed are principles for proper prioritization. This article investigates whether American ethicists Tom Beauchamp and James Childress's principle of justice may be helpful as a conceptual framework for reflections on prioritization of expensive biological therapies in the Danish healthcare system. We present an empirical study exploring the principles for prioritizing new expensive biological therapies. This study includes qualitative interviews with key Danish stakeholders experienced in antibody therapy and prioritizing resources for expensive medicines. Beauchamp and Childress's model only covers government-funded primary and acute healthcare. Based on the interviews, this study indicates that to be helpful in a Danish context this model should include equal access for citizens to government-funded primary and acute healthcare, costly medicine, and other scarce treatments. We conclude that slightly modified, Beauchamp and Childress's principle of justice might be useful as a conceptual framework for reflections on the prioritization of expensive biological therapies in the Danish healthcare system.

Guideline adherence and socioeconomic factors in Danish patients referred to secondary care for low back pain: a cross sectional study.

BACKGROUND: The pre-referral history of patients with low back pain referred to secondary care is poorly documented, and it is unclear whether it complies with clinical guideline recommendations; specifically, whether they have received appropriate treatment in primary care. This study describes the patient population referred to a spine clinic at a Danish hospital and investigates whether they have received an adequate course of treatment in primary care before referral. Furthermore, a possible association between primary care treatment and socioeconomic factors is estimated. METHODS: We examined self-reported data from 1035 patients with low back pain of at least eight weeks duration referred to secondary care at a medical spine clinic using a cross-sectional design. As an approximation to national clinical guidelines, the definition of an adequate course of treatment in primary care was at least five visits to a physiotherapist or chiropractor prior to referral. RESULTS: Patients were on average 53 years old, and 56% were women. The average Oswestry Disability Index score was 36, indicating a moderate level of disability. Nearly half of the patients reported pain for over a year, and 75% reported pain below knee level. Prior to referral, 33% of the patients had not received an adequate course of treatment in primary care. Based on multiple logistic regression with the three socioeconomic variables, age and sex in the model, those who were unemployed had an odds ratio of 2.35 (1.15-4.79) for not receiving appropriate treatment compared to employed patients. Similarly, the odds ratio for patients without vs. with health insurance was 1.71 (1.17-2.50). No significant association was observed with length of education. CONCLUSIONS: Despite national clinical guidelines recommending management for low back pain in primary care, one third of the patients had not received an adequate course of treatment before referral to secondary care. Moreover, the high probability of not having received recommended treatment for patients who were unemployed or lacked health insurance indicates an economic obstacle to adequate care. Therefore, reconsidering the compensation structure for the treatment of back pain patients is imperative to mitigate health inequality within low back pain management.

Caring Existentially and Spiritually for Young Children and Close Grandchildren of Life-Threatened Cancer Patients in Secularized Denmark.

PURPOSE: When children are given opportunities to talk about their existential and spiritual concerns and needs, different health risks related to parents' illness and death may be reduced. The existential and spiritual care and conversations provided during parents' and close grandparents' cancer illness are insufficient. This article presents a practical and theoretical perspective on how to care for the existential and spiritual needs of children at three different age stages. DATA SOURCES: Data from a research project guided the process of synthesizing the theoretical aspects with the practical. The theoretical perspective comprises Majbrit Guldin's theory of children's age-related grief reactions and James Fowler's three stages about children's spiritual and cognitive development. The empirical study is based on qualitative interviews with 16 children or close grandchildren of cancer patients at hospice. CONCLUSION: The theoretical and practical perspective function as a guide for existential and spiritual care and conversation with children at three different ages. The preschool child needs adults to support their growing spirituality and help them show, express, and understand their feelings. The school-aged child needs adults who listen to and acknowledge the child's understandings, experiences, and feelings as well as challenge their rigid thinking. The young adult needs adults who are willing to be there for them physically, mentally, socially, and spiritually in a genuine relationship. IMPLICATIONS FOR NURSING PRACTICE: The perspective might function well for nurses and other health professionals as it is generic and addresses barriers for communication with children found in different healthcare contexts.

Non-targeted and suspect screening analysis using ion exchange chromatography-Orbitrap tandem mass spectrometry reveals polar and very mobile xenobiotics in Danish drinking water.

Non-targeted and suspect screening analysis is gaining approval across the scientific and regulatory community to monitor the chemical status in the environment and thus environmental quality. These holistic screening analyses provides the means to perform suspect screening and go beyond to discover previously undescribed chemical pollutants in environmental samples. In a case study, we developed and optimized a high-resolution tandem mass spectrometry platform hyphenated with anion exchange chromatography to screen drinking water samples in Denmark. The optimized non-targeted screening method was able to detect anionic and polar compounds and was successfully applied to drinking water from two drinking water facilities. Following a data analysis pipeline optimization, anionic pesticide residues and other environmental contaminants were detected at confidence identification level 1 such as dimethachlor ESA, mecoprop, and dichlorprop in drinking water. In addition to these three substances, it was possible to detect another 1662 compounds, of which 97 were annotated at confidence identification level 2. More research is urgently needed to health risk prioritize the detected substances and to determine their concentrations.

The effect of ferritin-guided iron supplementation among Danish female first-time blood donors.

BACKGROUND: The identification of blood donors at risk of developing low hemoglobin (Hb) and subsequent intervention is expected to reduce donation-induced iron deficiency and low Hb among blood donors. This study explores the effects of ferritin-guided iron supplementation for female first-time donors implemented in four of five administrative regions in Denmark. STUDY DESIGN AND METHODS: We included 45,919 female first-time donors in this study. Hb values were determined in donations of included donors during a 2-year follow-up period. For each region, an intervention group (after implementation) and a control group (before implementation) were defined. The primary outcome was Hb below the donation threshold (7.8 mmol/L ~ 12.5 g/dL) at the time of donation, in the control group, and the intervention group, using logistic regression. The secondary outcome was the number of donations per donor given during the follow-up period. RESULTS: We observed a statistically significant decrease in the risk of female first-time donors experiencing a donation with low Hb after ferritin-guided iron supplementation was introduced: Odds ratio, 0.82; 95% confidence interval (CI), 0.71-0.95. We found a statistically significant increase in the number of donations per donor during the follow-up period after intervention; rate ratio: 1.05, 95% CI: 1.02-1.08. DISCUSSION: Ferritin-guided iron supplementation led to a significant reduction in the occurrence of low hemoglobin (Hb) levels among Danish female first-time blood donors. The intervention was additionally associated with an increase in the number of donations per donor.

Senior citizens' vitamin D supplements intake: evidence from Denmark.

BACKGROUND: Several public interventions have been designed in recent years to urge the intake of vitamin D supplements among the senior population to avoid the direct and indirect consequences associated with vitamin D deficiency. However, the effectiveness of these public campaigns remains quite limited. In an online survey, the current study investigates attitudes towards vitamin D supplements intake and associated behaviours in a representative sample of Danish senior citizens (N = 554) - that is, individuals aged 55 years and above. RESULTS: Approximately half of the sample reported taking vitamin D supplements in the preceding year. Furthermore, being male and having a positive perception of individuals' own health status increased the probability of being a non-user. Increasing confidence in the information provided by health authorities (such as medical doctors and pharmacies) is particularly critical for enhancing the likelihood of non-users to purchase vitamin D supplements. However, also encouraging the uptake of vitamin D supplements in specialized supermarkets with stands and promotions seems an appealing and practical solution to increase seniors' uptake of vitamin D supplements. CONCLUSIONS: The present study outlines the characteristics of senior Danish non-users of vitamin D supplements. Additionally, the research provides information on the strategies that could be applied by public organizations to foster vitamin D supplements intake among this target segment of the population. © 2023 The Authors.
