ABSTRACT

The study aim was to explore how Sámi healthcare staff experience working as an ethnic minority in the Norwegian healthcare system. This was a qualitative focus group and individual interview study inspired by interpretive description, with 14 participants. The results indicate that Sámi healthcare staff experience various degrees of cultural load in their jobs. This was shown through the two themes: "Feeling responsible for Sámi patients and non-Sámi colleagues" and "Feeling exhausted as a Sámi healthcare worker." To provide culturally safe care for all Sámi patients and their families, it is vital to ensure the well-being of the small number of Sámi healthcare personnel. Therefore, we emphasize the need for training programs for non-Sámi healthcare staff to provide them with the knowledge needed to support their encounters with Sámi patients in culturally safe ways. Sámi healthcare staff cannot take all responsibility for teaching their non-Sámi colleagues and acting as cultural mediators in all situations that non-Sámi staff find challenging. The risk of cultural load and burnout is very present. Nursing departments in universities and leaders in primary and secondary healthcare need to address these issues in order to ensure culturally safe care to all patients and support Sámi healthcare staff.

ABSTRACT

Background: Multidose drug dispensing (MDD) is an adherence aid where medicines are machine-dispensed in disposable unit bags, usually for a 14-day period. MDD replaces manually filled dosettes in many home care services in Norway. While evidence suggests that MDD can improve medication adherence and reduce errors, there are few studies on how patients manage MDD at home and how this affects their daily routines. Objective: The aim of the study is to identify factors influencing medication self-management behavior among MDD users living at home and explore how MDD affects medication self-management. Methods: We conducted semistructured interviews with 19 MDD users in Oslo between August 2019 and February 2020. The interviews were held at the participants' homes, and the interview transcripts were analyzed thematically. Results: All participants in the study received some form of assistance with medication management from home care services. This assistance ranged from MDD delivery every other week to actual assistance with medication administration multiple times daily. However, regardless of the level of assistance received, participants primarily managed their MDD medications themselves. Daily medication routines and knowledge about medicines varied among the participants, with some taking an active role in their medication management, while others relied on others to take responsibility. The degree of involvement seemed determined by motivation rather than capability. Conclusions: MDD can support medication self-management, but its effectiveness varies among patients. The level of medication management by MDD users is not solely determined by their actual capabilities. Factors such as interest in self-care and independence, available support, information, and cognitive capacity all play a role in determining the degree of autonomy.

ABSTRACT

Norway lobster Nephrops norvegicus, a prized decapod crustacean species, is found at different depths across the East Atlantic Ocean and Mediterranean Sea. Despite management efforts, the stocks are globally characterised as overexploited. In the present study, the impact of biogeographical boundaries on the phylogeographical and demographic population status was investigated within the Adriatic Sea, addressing important genetic indices for decapod functional conservation management. Central Mediterranean, Adriatic Sea A total of 482 individuals of Nephrops divided into the 12 samples were collected across biogeographical range of the Adriatic Sea. Using the mtDNA D-loop and microsatellite markers, methods of phylogeography and seascape genetics were applied to infer offshore versus coastal population divergence, demography and structure. Significant findings include genetic differentiation between offshore and coastal samples, with higher diversity indices in open waters. The limited gene flow observed between these two areas emphasises the self-sustained nature of coastal populations. Recent demographic changes in coastal populations reflect geographical constraints, fishing pressures and fluctuations in self-recruitment success. Additionally, the study reveals historical biogeographic events shaping the Adriatic populations, with evidence suggesting lineage divergence during the upper Pleistocene and postglacial recolonisation from southern Adriatic refugia. The role of biogeographical conditions in shaping genetic structure and limited gene flow between inshore and offshore areas underscore the need for improved management strategies, emphasising the importance of marine protected areas in conserving coastal populations and maintaining overall genetic diversity of the Norway lobster in the Adriatic Sea. Genomic monitoring within current management practices is recommended.

ABSTRACT

Obstructive sleep apnea (OSA) is highly prevalent in patients with asthma. Asthma, dose-dependently to its duration, promotes incident OSA, suggesting that asthma plays a role in OSA pathogenesis. We hypothesized that asthma-related inflammation alters breathing control mechanisms, specifically the carotid chemoreflex. Accordingly, we measured hypoxic ventilatory responses (HRV) in awake, unrestrained, ovalbumin (OVA)-sensitized Brown Norway rats and compared them with responses in sham-sensitized (SALINE) controls. To differentiate the role of allergic inflammation from bronchoconstriction, we repeated HVR after administration of formoterol, a long-acting bronchodilator. Blood and bronchoalveolar lavage (BAL) fluid were collected for quantification of inflammatory cytokines. The rise in ventilatory equivalent for O2 evoked by acute exposure to hypoxia was augmented following sensitization by OVA, whereas it remained stable after SALINE. This augmentation was driven by increased breathing frequency with no change in tidal volume. Tachypneic hyperventilation in normoxia was also observed with OVA. Neither the increased HVR nor excessive normoxic ventilation was affected by formoterol, suggesting that they were not secondary to lung mechanical constraints. Higher levels of inflammatory cytokines were observed in BAL fluid and serum of OVA vs. SALINE. In OVA, serum interleukin-5 correlated with change (baseline to post-sensitization) in ventilatory response to severe hypoxia (FIO2, 0.09). These observations are consistent with inflammation-induced enhancement of carotid chemoreflex function, i.e. increased controller gain, and they suggest a possible role for asthma-related allergic inflammation in the ventilatory instability known to promote upper airway collapse and sleep apnea in humans.

ABSTRACT

BACKGROUND: Calling for help is the first link in the chain of survival; however, few studies have investigated the challenges faced by frequent callers (FCs) to emergency medical communication centres (EMCCs). This study aimed to explore the characteristics of FCs and the nature of their calls to the Bergen EMCC, Norway. METHODS: This was a retrospective analysis of all emergency calls to the Bergen EMCC over three consecutive years (2019-2021). Bergen is the second-largest city in Norway, and the Bergen EMCC and ambulance services are part of the specialist medical service, covering a population of 460,000. The Bergen EMCC receives approximately 60,000 emergency calls per year. The study population comprised all adults identified during emergency medical calls. FCs were defined as individuals who registered five or more calls over 12 consecutive months during the three-year period. RESULTS: The analysis included approximately 50,000 individuals, who made > 90,000 calls during the study period. Of those, 1,594 (3.2%) were FCs, accounting for approximately one in four (21,339 of 90,085, 23.7%) calls. The FCs included more men (882 of 1,594 (55.3%) vs. 24,204 of 47,564 (50.9%)) and registered a lower proportion of calls with an acute degree of urgency (6,051 of 21,339 calls (28.4%) vs. 30,276 of 68,746 calls (44.0%)). Calls from FCs showed an even occurrence throughout the week, peaking between 19:00 h and 20:00 h. Compared with calls from non-FCs, calls from FCs had a higher proportion of 'no response/verbal referral to local emergency medical department' and involved a lower proportion of hospital transfers. The EMCC most frequently used the medical criterion 'Mental health problems/suicide' for calls from FCs. CONCLUSIONS: FCs were common, and more often men. The EMCC dispatched ambulances or admitted patients to hospitals less frequently following these calls. Many of these situations could be handled in other parts of the healthcare system, reducing the burden on EMCCs, and providing more suitable services for FCs. Thus, EMCCs should identify and adjust patient management to match their actual needs.

ABSTRACT

BACKGROUND: Intermediate care (IC) services bridge the transition for older patients from the hospital to the home. Despite the goal of involving individuals in their recovery process, these services often become standardised, leading to communication breakdowns. While evidence-based practices, such as the Four Habits Model (4HM), for effective communication are crucial for enhancing high-quality healthcare, research suggests their integration into routine practice remains limited. In this study, we aimed to investigate the implementation process of the 4HM through a two-day course that engaged healthcare professionals and managers in IC. METHODS: We conducted a process evaluation employing qualitative and quantitative methods: (i) individual interviews with three managers and two course participants pre-course, (ii) two focus group interviews with course participants (N = 11) and individual interviews with the same three managers post-course, and (iii) the NoMAD questionnaire (Normalisation MeAsure Development) administered four months later to assess the short- and long-term impact on course participants (N = 14). Reflexive thematic analyses were guided by Normalisation Process Theory (NPT), which offers insight into how new interventions become routine practices. The analysis of the NoMAD involved descriptive statistics. RESULTS: We identified four themes in the qualitative data: (i) Decoding Interactions: Making Sense of the 4HM in IC services, (ii) Fostering Change: Legitimising 4HM Through Staff Engagement, (iii) Harmonising Practice: Integrating 4HM into Complex Situations, and (iv) Embedding Value: Normalising the 4HM into Everyday Work. These themes illustrate the normalisation process of the 4HM course within IC, establishing standard practices. Healthcare professionals and managers highlighted the urgent need to integrate communication skills based on the 4HM into daily care. They noted positive changes in their communication habits following the course. The consistent findings from the NoMAD questionnaire underscore the sustainability of implementing the 4HM programme, as participants continue to utilise it in their clinical practice beyond the initial four-month period. CONCLUSION: The 4HM course programme was deemed feasible for expansion within IC services. Both managers and staff found its focus on addressing communication breakdowns and readiness for change sensible. The study findings may benefit the stakeholders involved in IC service routines, potentially improving services for older patients and relatives.

ABSTRACT

Skin diseases in Norway represents an important area of study due to their incidence and prevalence, yet ethnobotanical research in this context remains scarce. The aim of this study was to evaluate the knowledge of Norwegian traditional medicine regarding the treatment of skin diseases and cosmetic purposes through a comparative analysis with EMA monographs. Participants were surveyed using semi-structured interviews. The two samples comprised 22 individuals from Bodø and 26 individuals from other Norwegian communities, all of whom use medicinal plants for the treatment of skin diseases and cosmetic purposes. The indications for skin diseases identified in the study were compared with the European Union herbal monographs published by the European Medicines Agency. Fieldwork was conducted between June 2022 and September 2023, during which 42 plant species from 22 families were recorded. More than half of these plant species (65.38%) were used without European Medicines Agency-approved medical indications. From a public safety perspective, ensuring the safety of self-treatment for skin diseases is a critical research focus for future ethnobotanical studies.

ABSTRACT

The age-related loss of muscle mass is partly accounted for by the loss of sarcomeres in series, contributing to declines in muscle mechanical performance. Resistance training biased to eccentric contractions increases serial sarcomere number (SSN) in young muscle, however, maximal eccentric training in old rats previously did not alter SSN and worsened performance. A submaximal eccentric training stimulus may be more conducive to adaptation for aged muscle. The purpose of this study was to assess whether submaximal eccentric training can increase SSN and improve mechanical function in old rats. Twelve 32-month-old male F344/BN rats completed 4 weeks of submaximal (60% maximum) eccentric plantar-flexion training 3 days/week. Pre- and post-training, we assessed in-vivo maximum isometric torque at a stretched and neutral ankle angle, the passive torque-angle relationship, and the isotonic torque-velocity-power relationship. The soleus and medial gastrocnemius (MG) were harvested for SSN measurements via laser diffraction, with the untrained leg as a control. SSN increased 11% and 8% in the soleus and MG, respectively. Training also shifted optimal torque production towards longer muscle lengths, reduced passive torque 42%, and increased peak isotonic power 23%. Submaximal eccentric training was beneficial for aged muscle adaptations, increasing SSN, reducing muscle passive tension, and improving dynamic contractile performance.

ABSTRACT

BACKGROUND AND AIMS: Evidence of the effect of limiting off-premises alcohol trading hours is still scarce. This study tested the effect of a small extension in trading hours on alcohol sales in alcohol monopoly outlets in Norway. DESIGN: The extension of trading hours was implemented within a stepped-wedge cluster-randomized trial design. Eligible state monopoly outlets (n = 229) were clustered into trade districts (n = 62), which were block-randomized to one of three sequences regarding date of implementation: 1 September 2020 (n = 21 districts, 82 outlets), 1 December 2020 (n = 21 districts, 73 outlets) and 1 March 2021 (n = 20 districts, 74 outlets). Outcomes were followed-up for a 1-year period. SETTING AND PARTICIPANTS: Study participants were state monopoly outlets in urban and rural trade districts in all parts of Norway. MEASUREMENTS: Monthly alcohol sales in litres of pure alcohol per trade district and per outlet were measured from March 2020 to March 2022 (primary outcome). We applied a linear mixed-effect model with two-way fixed effects within a difference-in-difference framework. As a robustness check we considered the effects of cross-border trade and effects in subgroups of outlets. Trading hours in monopoly outlets were extended by 1 hour on Saturdays. The extension was permanent. Pre-intervention periods and not-yet-treated units served as control conditions. FINDINGS: We did not find a statistically significant effect of the small extension in trading hours on monthly alcohol sales (i) per trade district [average treatment effect: -185.5 litres, 95% confidence interval (CI) = -1159.9, 788.9] and (ii) per outlet (-35.3 litres, 95% CI = -142.1, 72.0). These findings were consistent across estimation methods and model specifications. CONCLUSION: There is no clear evidence that a small extension in off-premises trading hours affected alcohol sales in monopoly outlets in Norway.

ABSTRACT

Lyme borreliosis (LB), the most common tick-borne disease in Europe, is endemic to southern coastal Norway. LB commonly presents as erythema migrans, which can disseminate, resulting in more severe disease such as Lyme neuroborreliosis or arthritis. In Norway, public health LB surveillance is conducted via mandatory reporting of laboratory-confirmed disseminated cases. From 2012 to 2022, Norway's surveillance-reported incidence of laboratory-confirmed disseminated LB increased by 78%. Although surveillance provides estimates of the incidence of disseminated LB, this study sought to estimate the incidence of symptomatic LB to better understand Norway's LB disease burden. Two studies were identified that, when combined, estimated an LB seroprevalence of 6.8% in the general adult population in southern Norway. Utilizing data from these seroprevalence studies, public health surveillance, and results from literature searches indicating that 37% of seroconverted LB cases are symptomatic and that the duration of LB antibody detection ranges from 10 to 20 years, we estimated that there were 315-630 symptomatic LB cases per 100,000 adult population in five southern coastal counties in Norway in 2022 and 24-48 cases of symptomatic LB for every public health surveillance-reported LB case in adults in these five counties in Norway.

ABSTRACT

BACKGROUND: The centrality of human resources in the provision of healthcare suggests that Human Resource (HR) management and the use of Human Resource analytics - use of digital data to better understand, assess, plan and organize the workforce - can play an important role in this. However, data driven decision making in the field of human resource management is lagging, and the appropriation of HR analytics in the healthcare sector is limited. AIM: The current study explores the role of HR departments and the adoption of Human Resource analytics in four municipalities in Norway to obtain insights into what influences the use or lack of use of HR analytics. METHODS: Empirical data were generated through qualitative interviews with fourteen individuals working in HR departments, the municipal administration, and the healthcare services. Structurational theory guided the analysis. The findings show that none of the municipalities made extensive use of data to inform decision making related to human resource management or workforce planning. RESULTS AND CONCLUSION: Three conditions hampered or made irrelevant the use of HR analytics: a decoupling between the services and HR, a weak data-culture, and HR and decision-making processes involving a plurality of stakeholders. However, there were changes underway in all municipalities related to the role of HR and HR analytics.

ABSTRACT

BACKGROUND: In 2023, the first evidence-based classification for recurrent weight gain (RWG) after metabolic and bariatric surgery was introduced. It uses early and late follow-up weight loss benchmarks based on standard deviations (SD) of percentage total weight loss(%TWL) results from the large Dutch Audit for Treatment of Obesity (DATO) registry (n > 18,000). We aimed to validate this classification and confirm its clinical relevance with an external cohort. METHODS: The DATO-based classification defines all RWG as grade 1, as long as weight-loss does not drop below DATO's late-follow-up minus one SD benchmark (20%TWL). Grade 3 represents clear outliers whose RWG evolves below DATO's late follow-up minus two SD benchmark (10%TWL), with grade 2 in-between. Grades 2a/3a represent initial suboptimal clinical response, with nadir %TWL never exceeding DATO's early-follow-up minus one SD benchmark (25%TWL). Grades 2b/3b represent late clinical deterioration from nadir weight loss ≥ 25%TWL. We compared baseline characteristics, SD based benchmarks, RWG and comorbidities from the Scandinavian Obesity Surgery Registry Norway (SOReg-N) with these DATO-derived grades. RESULTS: The SOReg-N population (n = 3064) was comparable at baseline, with more sleeve gastrectomies (54% versus DATO 22.5%). The SD benchmarks were at early follow-up minus one SD 25.8%TWL, at 5 years minus one SD/minus two-SD 17.2%TWL/7.0%TWL (DATO 25%TWL/20%TWL/10%TWL). Percentage of patients and amount of RWG were similar to DATO. In line with DATO, comorbidities were predominant in grades 2a/3a, with least improvement in grade 3a. Also, grade 3b showed more favorable characteristics at baseline. CONCLUSION: The SOReg-N cohort confirmed the weight-loss benchmarks defining the DATO-derived grades, the distribution of patients and their RWG across the grades, and correlations between grades and comorbidities. Male gender, older age and comorbidities were predominant among patients with initial suboptimal clinical response (RWG grades 2a/3a), but not for late clinical deterioration (RWG grades 2b/3b). This classification can be used for populations with diverse weight loss trajectories and offers an evidence-based guide for clinical decision-making and standardization.

ABSTRACT

Mixed-species forests are, for multiple reasons, promising options for forest management in Central Europe. However, the extent to which interspecific competition affects tree hydrological processes is not clear. High-resolution dendrometers capture sub-daily variations in stem diameter; they can simultaneously monitor stem growth (irreversible changes in diameter) and water status (reversible changes) of individual trees. Using the information on water status, we aimed to assess potential effects of tree species mixture, expressed as local neighborhood identity, on night-time rehydration and water stress. We deployed 112 sensors in pure and mixed forest stands of European beech, Norway spruce, and Douglas fir on four sites in north-western Germany, measuring stem diameter in 10-minute intervals for a period of four years (2019-2022). In a mixture distribution model, we used environmental variables, namely soil matric potential, atmospheric vapor pressure deficit, temperature, precipitation, and neighborhood identity to explain night-time rehydration, measured as the daily minimum tree water deficit (TWDmin). TWDmin was used as a daily indicator of water stress and the daily occurrence of sufficient water supply, allowing for stem growth (potential growth). We found that species and neighborhood identity affected night-time rehydration, but the impacts varied depending on soil water availability. While there was no effect at high water availability, increasing drought revealed species-specific patterns. Beech improved night-time rehydration in mixture with Douglas fir, but not in mixture with spruce. Douglas fir however, only improved rehydration at a smaller share of beech in the neighborhood, while beech dominance tended to reverse this effect. Spruce was adversely affected when mixed with beech. At species level and under dry conditions, we found that night-time rehydration was reduced in all species, but beech had a greater capacity to rehydrate under high to moderate soil water availability than the conifers, even under high atmospheric water demand. Our study gives new insights into neighborhood effects on tree water status and highlights the importance of species-specific characteristics for tree-water relations in mixed-species forests. It shows that drought stress of European beech can be reduced by admixing Douglas fir, which may point towards a strategy to adapt beech stands to climate change.

ABSTRACT

Marteilia pararefringens is a protistan parasite that mainly infects the digestive gland of mussels Mytilus spp. Despite observations of marteiliosis in mussels since the 1970s, the reported host species has generally not been verified by molecular methods. The 3 closely related mussels Mytilus edulis, M. galloprovincialis, and M. trossulus cannot be distinguished morphologically and hybridise in regions where they overlap. Norway is the only country where both M. pararefringens and M. trossulus are known to occur. Here, we report the first detection of marteiliosis, caused by M. pararefringens, in M. trossulus and an M. edulis-M. trossulus hybrid in a heliothermic oyster pond-a poll-in Hardangerfjorden, Norway. The observed infections were severe, containing early, intermediate, and advanced (sporulating) stages present in the digestive epithelium. There was no host reaction associated with the infections. This finding confirms that all known Mytilus species present in Europe are susceptible to M. pararefringens.

ABSTRACT

The Ore Mountains were historically one of the most polluted areas in Europe, where high sulphur dioxide concentrations and a high level of atmospheric deposition led to a vast decline in Norway spruce stands in the mountain ridge plateau. In this article, we evaluate the trends in the atmospheric deposition load, soil chemistry, tree nutrition, crown defoliation and height increment in a network of twenty research plots monitored for last thirty years in this region. The decrease in sulphur and nitrogen deposition was most pronounced at the end of 1990s. Extreme values of sulphur deposition (100-200 kg.ha-1.year-1) were recorded in throughfall under mature Norway spruce stands in the late 1970s, and after felling of the damaged stand, the deposition levels were comparable to open plot bulk deposition. Nitrogen deposition decreased more slowly compared with sulphur, and a decrease in base cation deposition was observed concurrently. The current deposition load is low and fully comparable to other mountain areas in central Europe. Accordingly, the health of young spruce stands, as assessed by defoliation and height increment, has improved and now corresponds to the Czech national average. On the other hand, no significant changes were observed in the soil chemistry, even though some of the plots were limed. Acidic or strongly acidic soil prevails, often with a deficiency of exchangeable calcium and magnesium in the mineral topsoil, as well as decreases in available phosphorus. This is reflected in the foliage chemistry, where we see an imbalance between a relatively high content of nitrogen and decreasing contents of phosphorus, potassium and calcium. Despite the observed positive trends in air quality and forest health, the nutritional imbalance on acidified soils poses a risk for the future of forest stands in the region.

ABSTRACT

Plant defence mechanisms, including physical barriers like toughened bark and chemical defences like allelochemicals, are essential for protecting them against pests. Trees allocate non-structural carbohydrates (NSCs) to produce secondary metabolites like monoterpenes, which increase during biotic stress to fend off pests like the Eurasian spruce bark beetle, ESBB (Ips typographus). Despite these defences, the ESBB infests Norway spruce, causing significant ecological damage by exploiting weakened trees and using pheromones for aggregation. However, the mechanism of sensing and resistance towards host allelochemicals in ESBB is poorly understood. We hypothesised that the exposure of ESBB to spruce allelochemicals, especially monoterpenes, leads to an upsurge in the important detoxification genes like P450s, GSTs, UGTs, and transporters, and at the same time, genes responsible for development must be compromised. The current study demonstrates that exposure to monoterpenes like R-limonene and sabiene effectively elevated detoxification enzyme activities. The differential gene expression (DGE) analysis revealed 294 differentially expressed (DE) detoxification genes in response to R-limonene and 426 DE detoxification genes in response to sabiene treatments, with 209 common genes between the treatments. Amongst these, genes from the cytochrome P450 family 4 and 6 genes (CP4 and CP6), esterases, glutathione S-transferases family 1 (GSTT1), UDP-glucuronosyltransferase 2B genes (UDB), and glucose synthesis-related dehydrogenases were highly upregulated. We further validated 19 genes using RT-qPCR. Additionally, we observed similar high expression levels of detoxification genes across different monoterpene treatments, including myrcene and α-pinene, suggesting a conserved detoxification mechanism in ESBB, which demands further investigation. These findings highlight the potential for molecular target-based beetle management strategies targeting these key detoxification genes.

ABSTRACT

The common eider, Somateria mollissima mollissima (Chordata; Aves; Anseriformes; Anatidae), is a large sea duck with a circumpolar distribution. We here describe a chromosome-level genome assembly from an individual female. The haplotype-resolved assembly contains one pseudo-haplotype spanning 1205 megabases (with both Z and W sex chromosomes) and one pseudo-haplotype spanning 1080 megabases. Most of these two assemblies (91.13% and 93.18%, respectively) are scaffolded into 32 autosomal chromosomal pseudomolecules plus Z and W for pseudo-haplotype one. The BUSCO completeness scores are 94.0% and 89.9%, respectively, and gene annotations of the assemblies identified 17,479 and 16,315 protein coding genes. Annotation of repetitive sequences classify 17.84 % and 14.62 % of pseudo-haplotype one and two, respectively, as repeats. The genome of the common eider will be a useful resource for the widely distributed northern species in light of climate change and anthropogenic threats.

ABSTRACT

A fifteen-month-old Pembroke Welsh corgi with respiratory distress, exercise intolerance, and moderate regenerative anemia was referred to The Norwegian University of Life Sciences, Small Animal Hospital.Hematology revealed moderate regenerative anemia without evidence of hemolysis. Thoracic radiographs showed a generalized mixed interstitial to alveolar lung pattern and enlarged pulmonary arteries. Changes suggestive of moderate pulmonary hypertension were noted on echocardiography. Baermann fecal diagnostic flotation identified large numbers of Angiostrongylus vasorum larvae, and the AngioDetect serological antigen test was positive. The dog was treated with a two-week course with fenbendazole (51 mg/kg q24h po) and topical imidacloprid/moxidectin (250 mg/62.5 mg) and a one-week course with sildenafil (0.45 mg/kg q12h po). Complete clinical, clinicopathological and echocardiographic resolution was observed after only four weeks. Rapid improvement of echocardiographic abnormalities in cases with suspected pulmonary hypertension is not usually reported in cases with angiostrongylosis.Infection with A. vasorum should be considered in dogs with respiratory signs and bleeding tendencies, even in countries with no endemic history or reported cases.

ABSTRACT

BACKGROUND: Available data suggest that general practitioners (GPs) in Germany use complementary and alternative medicine (CAM) modalities more frequently than GPs in many other countries. We investigated the country differences perceived by general practitioners who have worked in Germany and in one of four other European countries with regard to the role of complementary and alternative treatments in primary care. METHODS: In this qualitative study we conducted semi-structured interviews with 12 GPs who had worked both in Germany and Italy, the Netherlands, Norway or the United Kingdom (UK; n = 3 for each of the four countries). Participants were asked how they perceived and experienced country differences regarding health system, relevance of CAM modalities, the role of evidence-based medicine (EBM) and science, and how they handle so-called indeterminate situations. For the analysis, we followed a thematic analysis approach according to Braun and Clarke with focus on themes that cover CAM. RESULTS: Participants unanimously reported that they perceived CAM to be more relevant in general practice in Germany compared to the other countries. We identified four overarching themes in relation to the perceived reasons for these differences. Firstly, physicians with experiences in countries with a strong EBM and science orientation (Netherlands, Norway and the UK) considered the deeply ingrained view in national healthcare systems and GP communities that CAM modalities are not evidence-based as the main reason for the lower use of CAM by GPs. Secondly, extensive training of communication skills was cited as a reason that reduced the need for CAM in the Netherlands, Norway and the UK. Thirdly, differences in patient expectations and demands were perceived as a factor contributing to greater utilisation of CAM by German GPs compared to the other countries. Finally, country-specific reimbursement mechanisms were considered as a factor influencing the role of CAM in general practice. CONCLUSIONS: The study results point to major differences between countries with regard to the role of CAM in GP care. Differences in basic attitudes in the discipline of general practice, patient expectations and system conditions appear to play an important role here.

ABSTRACT

BACKGROUND: Substance use is a global health concern and early onset among adolescents increases health risks. We explore national overall trends in prevalence and trends in socioeconomic inequalities in past year alcohol intoxication, cannabis use, and use of other illicit drugs among Norwegian adolescents (ages ∼ 15-19 years of age) between 2014 and 2022. METHOD: The present study builds on data from a nationwide repeated cross-sectional survey collected in 2014-2016 (T1), 2017-2019 (T2), 2021 (T3) and 2022 (T4). In total 415,560 adolescents (50.3% girls) completed the questionnaire during the study period. Trends in socioeconomic inequalities were assessed using the Slope Index of Inequality (SII) and the Relative Index of Inequality (RII). RESULTS: While the prevalence of alcohol intoxication remained fairly stable, the prevalence of cannabis and other illicit drug use increased between 2014 and 2022 among upper secondary school boys (13.3-17.6%, and 2.0-5.2%, respectively) and girls (8.8-12.8%, and 1.1-2.7%, respectively). Similar trends were observed among 10th-grade adolescents. Boys were more likely than girls to use cannabis or other illicit drugs, but the gender gap in cannabis use narrowed during the study period. Among upper secondary girls, use of cannabis and other illicit drugs was higher among those from less affluent backgrounds, with absolute and relative inequalities in cannabis use increasing between 2014 and 2022. Small inequalities in cannabis use and decreasing relative inequalities in the use of other illicit drug were observed among upper secondary boys. CONCLUSIONS: The increasing use of cannabis and other illicit drugs among Norwegian adolescents is concerning. Future studies should explore the underlying causes of this rise and explore the complex factors influencing adolescent substance use behaviours. A comprehensive understanding of these factors is essential for developing targeted and effective interventions.
