Background Reducing socioeconomic inequalities in cancer is a priority for the public health agenda. A systematic assessment and benchmarking of socioeconomic inequalities in cancer across many countries and over time in Europe is not yet available. Methods Census-linked, whole-of-population cancer-specific mortality data by socioeconomic position, as measured by education level, and sex were collected, harmonized, analysed, and compared across 18 countries during 1990–2015, in adults aged 40–79. We computed absolute and relative educational inequalities; temporal trends using estimated-annual-percentage-changes; the share of cancer mortality linked to educational inequalities. Findings Everywhere in Europe, lower-educated individuals have higher mortality rates for nearly all cancer-types relative to their more highly-educated counterparts, particularly for tobacco/infection-related cancers [relative risk of lung cancer mortality for lower- versus higher-educated = 2.4 (95% confidence intervals: 2.1–2.8) among men; = 1.8 (95% confidence intervals: 1.5–2.1) among women]. However, the magnitude of inequalities varies greatly by country and over time, predominantly due to differences in cancer mortality among lower-educated groups, as for many cancer-types higher-educated have more similar (and lower) rates, irrespective of the country. Inequalities were generally greater in Baltic/Central/East-Europe and smaller in South-Europe, although among women large and rising inequalities were found in North–Europe (relative risk of all cancer mortality for lower- versus higher-educated ≥1.4 in Denmark, Norway, Sweden, Finland and the England/Wales). Among men, rate differences (per 100,000 person-years) in total-cancer mortality for lower-vs-higher-educated groups ranged from 110 (Sweden) to 559 (Czech Republic); among women from approximately null (Slovenia, Italy, Spain) to 176 (Denmark). Lung cancer was the largest contributor to inequalities in total-cancer mortality (bet

Objectives The aims of this study were to investigate the association between educational level and musculoskeletal pain and physical function, respectively, in persons 60–70 years old, and to investigate if the association changed from 2010 to 2017. Design and participants This is a sex-stratified, cross-sectional study based on data from the Danish Health and Morbidity Survey in 2010 (n=15 165) and in 2017 (n=14 022). Self-reported data from respondents who were 60–70 years old and reported data for pain or physical function, sociodemographic, education and behavioural factors were included. Primary outcome measures Prevalence of pain and physical limitations. Results Among men, a high educational level was associated with reduced odds of pain compared with low educational level (OR 0.56 (95% CI 0.41; 0.74)). Medium and high educational levels were associated with reduced odds of pain in women (0.74 (0.59; 0.92) and 0.64 (0.41; 1.00), respectively). High educational level was associated with reduced odds of physical limitations in men (0.35 (0.19; 0.65)) and women (0.33 (0.14; 0.78)). The interaction terms between time and education were not associated with pain and physical function, respectively. Conclusion High education was associated with reduced musculoskeletal pain and reduced limitations of physical function. The association between education and musculoskeletal pain and physical function did not change significantly over time. Musculoskeletal pain during the past 14 days and chronic pain among old men and women 60–70 years and their level of physical function contribute to important knowledge of a group near the retirement age. The future perspectives illustrate trends and importance of focusing on adapting job accommodations for senior workers., Objectives The aims of this study were to investigate the association between educational level and musculoskeletal pain and physical function, respectively, in persons 60–70 years old, and to investigate if the association changed from 2010 to 2017.

Home-based pulmonary telerehabilitation (PTR) has been proposed to be equivalent to supervised outpatient pulmonary rehabilitation (PR) but available randomised trials have failed to reach the minimal important changes (MIC). The purpose of this study was to analyse the proportion of MIC responders and non-responders on short-term (10 weeks from baseline) and long-term (62 weeks from baseline) in total and between groups in 134 patients with COPD randomised (1:1) to either home-based PTR or traditional hospital-based outpatient PR. Difference between PTR and PR on 6MWD response proportion could not be shown at 10 (OR=0.72, CI=0.34 to 1.51, p=0.381) or 62 weeks (OR=1.12, CI=0.40 to 3.14, p=0.834). While the evidence and knowledge of PTR accumulate, outpatient supervised PR for now remains the standard of care, with home-based PTR as a strong secondary option for those unable to attend out-patient programmes.

Objectives In the randomized controlled trial PANTHEM, the prophylactic effect of oral amoxicillin or clindamycin is investigated in patients receiving chronic haemodialysis (HD). However, data on plasma concentrations of these antibiotics during HD are sparse. This study aims to determine if the plasma concentration of amoxicillin and clindamycin is sufficient during HD after oral administration of amoxicillin and clindamycin at three different time intervals prior to the HD procedure. Methods Adult patients receiving chronic HD were investigated twice with an interval of at least 7 days starting with either a tablet of 500/125 mg amoxicillin/clavulanic acid or a tablet of 600 mg clindamycin. Patients were randomized to take the antibiotics either 30, 60 or 120 min prior to the HD procedure. Plasma antibiotic concentrations were measured at start, midway and at the end of HD. A lower threshold was set at 2.0 mg/L for amoxicillin and at 1.0 mg/L for clindamycin. In addition, a population pharmacokinetic (PK) analysis was performed, assessing PTA. Results In the amoxicillin cohort (n = 37), 84% of patients and 95% of all plasma amoxicillin concentrations were above or at the threshold throughout the dialysis procedure. In the clindamycin cohort (n = 33), all concentrations were above the threshold throughout the dialysis procedure. Further, in all patients, the mean plasma concentration of both amoxicillin and clindamycin across the HD period was well above the threshold. Finally, the PK model predicted a high PTA in the majority of patients. Discussion In patients on chronic HD, oral administration of amoxicillin/clavulanic acid (500/125 mg) or clindamycin (600 mg) within 30–120 min prior to HD leads to a sufficient prophylactic plasma concentration across the HD period., Objectives: In the randomized controlled trial PANTHEM, the prophylactic effect of oral amoxicillin or clindamycin is investigated in patients receiving chronic haemodialysis (HD).

Patients with long-term health sequelae of COVID-19 (post-COVID-19 condition) experience both physical and cognitive manifestations. However, there is still uncertainty about the prevalence of physical impairment in these patients and whether there is a link between physical and cognitive function. The aim was to assess the prevalence of physical impairment and investigate the association with cognition in patients assessed in a post-COVID-19 clinic. In this cross-sectional study, patients referred to an outpatient clinic ≥ 3 months after acute infection underwent screening of their physical and cognitive function as part of a comprehensive multidisciplinary assessment. Physical function was assessed with the 6-Minute Walk Test, the 30 s Sit-to-Stand Test and by measuring handgrip strength. Cognitive function was assessed with the Screen for Cognitive Impairment in Psychiatry and the Trail Making Test-Part B. Physical impairment was tested by comparing the patients’ performance to normative and expected values. Association with cognition was investigated using correlation analyses and the possible explanatory variables regarding physical function were assessed using regression analyses. In total, we included 292 patients, the mean age was 52 (±15) years, 56% were women and 50% had been hospitalised during an acute COVID-19 infection. The prevalence of physical impairment ranged from 23% in functional exercise capacity to 59% in lower extremity muscle strength and function. There was no greater risk of physical impairment in previously hospitalised compared with the non-hospitalised patients. There was a weak to moderate association between physical and cognitive function. The cognitive test scores had statistically significant prediction value for all three outcomes of physical function. In conclusion, physical impairments were prevalent amongst patients assessed for post-COVID-19 condition regardless of their hospitalisation status and these were associated with

BACKGROUND: The purpose of the study was to quantify the association between body weight and health by estimating the expected lifetime with and without diabetes (diabetes-free life expectancy) at age 30 and 65. In addition, the diabetes-free life expectancy was stratified by educational level.METHODS: Life tables by sex, level of education and obese/not obese were constructed using nationwide register data and self-reported data on body weight and height and diabetes from the Danish National Health Survey in 2021. Diabetes-free life expectancies were estimated by Sullivan's method.RESULTS: The difference in life expectancy between not obese 30-year-old men with a long and a short education was 5.7 years. For not obese women, the difference was 4.1 years. For obese men and women, the difference in life expectancy at age 30 was 7.0 and 5.2 years. Women could expect more years without and fewer years with diabetes than men regardless of body weight and educational level. Diabetes-free life expectancy differed by 6.9 years between not obese 30-year-old men with a short and a long education and by 7.7 years for obese men with a short and a long education. For women, the differences were 5.9 and 6.6 years.CONCLUSION: The results demonstrate an association of obesity and educational level with life expectancy and diabetes-free life expectancy. There is a need for preventive efforts to reduce educational inequality in life expectancy and diabetes-free life expectancy. Structural intervention will particularly benefit overweight people with short education.

The organic matter content of marine sediments is often used to infer past changes in ocean conditions. However, the organic carbon pool preserved in coastal sediments is a complex mixture derived from different sources and may not reflect in situ processes. In this study, we combine taxonomic identification of reworked palynomorphs with pyrolysis organic geochemistry and reflected-light organic petrographic microscopy to investigate the provenance, composition and preservation of organic matter in a marine sediment core retrieved from the NE Greenland shelf. Our study reveals continuous yet variable input of land-derived organic carbon to the marine environment throughout the late Younger Dryas–Holocene, with the highest input of inert carbon in the late Younger Dryas. Although the sediments contain some recent marine palynomorphs, there is no other evidence of fresh marine organic carbon. In contrast, our results indicate that these shelf sediments represent a significant sink of recycled organic carbon. The results of pyrolysis geochemistry revealed that ~90% of the total organic carbon in the sediments is inert. The organic petrography analyses revealed that >70–84% of the organic carbon in the sediment core is terrigenous. Reworked dinoflagellate cysts showed a continuous provenance of Cretaceous land-derived material, most likely from the nearby Clavering Island. Our study points to the importance of constraining the organic matter origin, composition and preservation in marine sediments to achieve more accurate palaeoenvironmental reconstructions based on organic proxies.

We investigate the relationship between business practices and enterprise productivity using panel data with matched employer and employee information from Myanmar. The data show that micro, small, and medium-sized manufacturing enterprises in Myanmar typically adopt only a few modern business practices, and the persistence in the use is extremely low. Even so, we find a positive and economically important association between business practices and productivity. Specifically, the empirical results show that a one standard deviation difference in applied business practices (equivalent to applying an additional 4 to 5 of the 20 business practices in focus) is associated with an 8–10 per cent difference in labour productivity. Utilising the employer–employee information to estimate Mincer-type wage regressions, we find that workers receive about half to two-thirds of the productivity gain in higher wages. Overall, our findings support the notion of business practices as a production technology, and we find that workers and managers split the productivity gains evenly.

BACKGROUND: Studies of period changes in educational inequalities in mortality have shown important changes over time. It is unknown whether a birth cohort perspective paints the same picture. We compared changes in inequalities in mortality between a period and cohort perspective and explored mortality trends among low-educated and high-educated birth cohorts. DATA AND METHODS: In 14 European countries, we collected and harmonised all-cause and cause-specific mortality data by education for adults aged 30-79 years in the period 1971-2015. Data reordered by birth cohort cover persons born between 1902 and 1976. Using direct standardisation, we calculated comparative mortality figures and resulting absolute and relative inequalities in mortality between low educated and high educated by birth cohort, sex and period. RESULTS: Using a period perspective, absolute educational inequalities in mortality were generally stable or declining, and relative inequalities were mostly increasing. Using a cohort perspective, both absolute and relative inequalities increased in recent birth cohorts in several countries, especially among women. Mortality generally decreased across successive birth cohorts among the high educated, driven by mortality decreases from all causes, with the strongest reductions for cardiovascular disease mortality. Among the low educated, mortality stabilised or increased in cohorts born since the 1930s in particular for mortality from cardiovascular diseases, lung cancer, chronic obstructive pulmonary disease and alcohol-related causes. CONCLUSIONS: Trends in mortality inequalities by birth cohort are less favourable than by calendar period. In many European countries, trends among more recently born generations are worrying. If current trends among younger birth cohorts persist, educational inequalities in mortality may further widen.

In copper smelting processes, acidic effluents are generated that contain inorganic contaminants such as arsenic and copper. Nowadays, the treatment of wastewater is done by physicochemical methods without copper recovery. Electrodialysis is an alternative process that can recover copper. Moreover, when electrocoagulation is applied to remove arsenic from wastewater, a more stable final sludge of less volume is obtained. The present research studies the application of a combined electrodialysis and electrocoagulation process to (1) recover Cu and (2) precipitate and remove arsenic simultaneously in the same batch reactor, using synthetic wastewater that simulates wastewater from a copper smelter. Copper and arsenic could be removed and separated by the electrodialysis part, and the electrocoagulation of arsenic was verified. With electrodialysis, the arsenic and copper removals were 67% and 100%, respectively, while 82% of the arsenic arriving at the electrocoagulation part of the cell could be precipitated and removed by this process. Initial concentrations were around 815 mg L−1 Cu and 7700 mg L−1 As. The optimal current was found to be 1.36 A due to the shorter treatment times necessary to get removal percentages, recovery percentages and energy/removed copper mass ratios in the same ranges as the values achieved with a current of 1.02 A. In summary, the combined process is a promising tool for simultaneous copper recovery and arsenic removal.

Fibroblast growth factor 21 (FGF21) plays a key role in hepatic lipid metabolism and long-acting FGF21 analogs have emerged as promising drug candidates for the treatment of nonalcoholic steatohepatitis (NASH). It remains to characterize this drug class in translational animal models that recapitulate the etiology and hallmarks of human disease. To this end, we evaluated the longacting FGF21 analog PF-05231023 in the GAN (Gubra Amylin NASH) diet-induced obese (DIO) and biopsy-confirmed mouse model of NASH. Male C57BL/6J mice were fed the GAN diet high in fat, fructose, and cholesterol for 34 wk before the start of the study. GAN DIO-NASH mice with biopsy-confirmed NAFLD Activity Score (NAS 5) and fibrosis (stage F1) were biweekly administered with PF-05231023 (10 mg/kg sc) or vehicle (sc) for 12 wk. Vehicle-dosed chow-fed C57BL/6J mice served as healthy controls. Pre-to-post liver biopsy histopathological scoring was performed for within-subject evaluation of NAFLD Activity Score (NAS) and fibrosis stage. Terminal endpoints included quantitative liver histology and transcriptome signatures as well as blood and liver biochemistry. PF-05231023 significantly reduced body weight, hepatomegaly, plasma transaminases, and plasma/liver lipids in GAN DIO-NASH mice. Notably, PF-05231023 reduced both NAS (2-point improvement) and fibrosis stage (1-point improvement). Improvements in NASH and fibrosis severity were supported by reduced quantitative histological markers of steatosis, inflammation, and fibrogenesis as well as improvements in disease-associated liver transcriptome signatures. In conclusion, PF-05231023 reduces NASH and fibrosis severity in a translational biopsy-confirmed mouse model of NASH, supporting development of FGF21 analogs for the treatment of NASH.

Cuba and Denmark represent states with different welfare models that have reached the same level of life expectancy. The purpose was to investigate and compare mortality changes in the two countries. Systematically collected information on population numbers and deaths for the entire Cuban and Danish populations was the basis of life table data used to quantify differences in the change in age-at-death distributions since 1955, age-specific contributions to differences in life expectancy, lifespan variation, and other changes in mortality patterns in Cuba and Denmark. Life expectancy in Cuba and Denmark converged until 2000, when the increase in life expectancy for Cuba slowed down. Since 1955, infant mortality has fallen in both countries but mostly in Cuba. Both populations experienced compression of mortality as lifespan variation decreased markedly, primarily due to postponement of early deaths. Given the different starting point in the mid-1900s and living conditions for Cubans and Danes, health status achieved among Cubans is striking. A rapidly ageing population is challenging both countries, but Cuban health and welfare are further burdened by a deteriorating economy in recent decades.

BACKGROUND: Area deprivation is associated with adverse mental health outcomes. In Denmark, urban regeneration is being used to dissolve concentrated socio-economic area deprivation and ethnic segregation. However, evidence on how urban regeneration affects mental health of residents is ambiguous partly due to methodological challenges. This study investigates if urban regeneration affects users of antidepressant and sedative medication among residents in an exposed and control social housing area in Denmark.METHODS: Using a longitudinal quasi-experimental design we measured users of antidepressant and sedative medication in one area undergoing urban regeneration compared with a control area. We measured prevalent and incident users from 2015 to 2020 among non-Western and Western women and men and used logistic regression to measure annual change in users over time. Analyses are adjusted for a covariate propensity score estimated using baseline socio-demographic characteristics and general practitioner contacts.RESULTS: Urban regeneration did not affect the proportion of prevalent nor incident users of antidepressant and sedative medication. However, levels were high in both areas compared with the national average. Descriptive levels of prevalent and incident users were generally lower among residents in the exposed area compared with the control area for most years and stratified groups confirmed by the logistic regression analyses.CONCLUSION: Urban regeneration was not associated with users of antidepressant or sedative medication. We found lower levels of antidepressant and sedative medication users in the exposed area compared with the control area. More studies are needed to investigate the underlying reasons for these findings, and whether they could be related to underuse.

Motivation: Workplace training is an indispensable part of workforce skill development, but it is often provided irregularly and selectively in private enterprises. This is a missed opportunity given its potential to contribute to employee wellbeing and human capital development, and to boost firm performance. Purpose: We examine workplace training provision and private returns to training in Myanmar, a country with a severely constrained formal educational system and underperforming private sector. Methods and approach: We use linked employer-worker panel data from micro, small and medium manufacturing enterprises in Myanmar. Our regression framework includes controls for production factors and other standard enterprise and owner characteristics, including employee and owner skills, and unobservable time-invariant employee and firm heterogeneity. Findings: First, we document a low prevalence of training in manufacturing enterprises. Second, we find a wage premium associated with training of about 8%. Third, we show that workplace training is offered selectively to workers and when this is the case, the wage gap between trained and untrained workers doubles. Fourth, we find that prior training (in other firms) or certified training do not contribute to higher wages, indicating that training is largely firm-specific. Finally, we find that the wage returns to training are particularly high for women and among least educated workers. Policy implications: Considering the wage return as a lower bound of productivity gains from training, our results suggest that government support of workplace training programs in private enterprises could help increase performance of the manufacturing sector in Myanmar. High returns to training among the least educated workers indicate that training could improve the overall income distribution in the economy.

In the present study, the assessment of heavy metal contaminant migration from fresh mine tailings was conducted using the electrokinetic remediation technique (EKR). In this sense, a pilot EKR cell was designed to evaluate the recovery potential of copper, nickel, and cobalt species. In particular, the focus was on the impacts of electric field intensity and pH in initial mixture and testing their interaction in copper, nickel, and cobalt migration. Experiments were made using a 22 factorial experimental design with a central point, using DC electric fields from 1.0 to 2.0 V cm−1 and H2SO4 pretreatment solutions from 1.0 to 2.0 mol L−1, along with an ANOVA test with error reduction. The metal removal rates were approximately 7% for cobalt, neglectable for copper, and 6% for nickel. In the best cases, the highest concentrations by migration at the cathodic zone were 11%, 31%, and 30%, respectively. According to ANOVA tests, factor interaction was proven for each metal in the half cell near the cathode and the closest zone from the cathode specifically. Both factors affected metal concentrations, which indicates that when the goal aims for species accumulation in a narrower section, each factor has a significant effect, and their interaction makes a proven enhancement. Thus, using 2.0 V cm−1 and 2.0 mol L−1 showed a high improvement in metal concentration in the cathodic zone.

The Oxfordian–Ryazanian was a period of widespread deposition of marine organic-rich mud-stones in basins formed during the early phases of the rifting that heralded the formation of the present-day North Atlantic. Occasionally, uninterrupted deposition prevailed for 20 million years or more. Today, mudstones of this time interval are found on the shelves bordering the North Atlantic and adjacent areas from Siberia to the Netherlands. Here, we report data on two fully cored boreholes from Wollaston Forland (North-East Greenland, approx. 74° N), which represent an uninterrupted succession from the upper Kimmeridgian to the Hauterivian. The boreholes record basin development at two different positions within an evolving halfgraben, located at the margin of the main rift, and thus partially detached from it. Although the overall depositional environment remained an oxygen-restricted deep-shelf setting, rifting-related changes can be followed through the succession. The Kimmeridgian was a period of eustatic highstand and records the incipient rifting with a transgressive trend straddling the transition to the lower Volgian by a gradual change from deposits with high levels of total organic carbon (TOC) and kerogen rich in allochthonous organic matter to deposits with lower TOC and a higher proportion of autochthonous organic matter. This is followed by a slight regressive trend with lower TOC and increased proportions of allochthonous organic matter until rifting culminated in the middle Volgian–Ryazanian, indicated by increasing autochthonous organic matter and higher TOC, which prevailed until basin ventilation occurred towards the end of the Ryazanian. The properties of the reactive kerogen fraction remained rather stable irrespective of TOC, underlining the effect of terrigenous matter input for TOC. These variations are also captured by biological markers and stable carbon isotopes. The deposits are very similar to equivalent successions elsewhere in the proto-N

Two shallow cores drilled in northern Wollaston Forland, North-East Greenland, provide a combined section covering the upper Kimmeridgian (Upper Jurassic) – Barremian (Lower Cretaceous) and comprising the Bernbjerg, Lindemans Bugt, Palnatokes Bjerg and Stratumbjerg Formations. A new lithostratigraphic unit, the Storsletten Member, is defined within the Lindemans Bugt For-mation. The black mudstone-dominated intervals are dated primarily by dinoflagellate cysts and ammonites, whereas the calcareous mudstones of the Palnatokes Bjerg Formation – sandwiched between the black mudstones – are dated by calcareous nannofossils. The stratigraphy demon-strates an almost complete succession in the Rødryggen-1 core, representing a deeper position in the basin, where the hiatus at the latest Jurassic rift climax predicted in previous models for the eastern Wollaston Forland Basin is absent. In contrast, the Brorson Halvø-1 core represents a position closer to a block crest where unconformities developed. In combination, the cores provide a key biostratigraphic reference section for the Jurassic–Cretaceous boundary interval in the Arctic.

Introduction Patients receiving haemodialysis are at increased risk of arrhythmias and sudden cardiac death, but data on arrhythmia burden and the pathophysiology remain limited. Among potential risk factors, hypoglycaemia is proposed as a possible trigger of lethal arrhythmias. The development of implantable loop recorders (ILR) and continuous glucose monitoring (CGM) enables long-term continuous ECG and glycaemic monitoring. The current article presents the protocol of a study aiming to increase the understanding of arrhythmias and risk factors in patients receiving haemodialysis. The findings will provide a detailed exploration of the burden and nature of arrhythmias in these patients including the potential association between hypoglycaemia and arrhythmias. Methods and analysis The study is an investigator-initiated, prospective, multicentre cohort study recruiting 70 patients receiving haemodialysis: 35 with diabetes and 35 without diabetes. Participants are monitored with ILRs and CGM for 18 months follow-up. Data collection further includes a monthly collection of predialysis blood samples and dialysis parameters. The primary outcome is the presence of clinically significant arrhythmias defined as a composite of bradycardia, ventricular tachycardia, or ventricular fibrillation. Secondary outcomes include the characterisation of clinically significant arrhythmias and other arrhythmias, glycaemic characteristics, and mortality. The data analyses include an assessment of the association between arrhythmias and hypoglycaemia and hyperglycaemia, baseline clinical variables, and parameters related to kidney failure and the haemodialysis procedure. Ethics and dissemination The study has been approved by the Ethics Committee of the Capital Region of Denmark (H-20069767). The findings will be presented at national and international congresses as well as in international peer-reviewed scientific journals., Introduction Patients receiving haemodialysis are at increased risk of arrhythmias and sudden cardiac death, but data on arrhythmia burden and the pathophysiology remain limited. Among potential risk factors, hypoglycaemia is proposed as a possible trigger of lethal arrhythmias. The development of implantable loop recorders (ILR) and continuous glucose monitoring (CGM) enables long-term continuous ECG and glycaemic monitoring.

OBJECTIVES To identify and prioritize technical procedures for simulation-based training to be integrated into the thoracic surgical curriculum. METHODS A 3-round Delphi survey was conducted from February 2022 to June 2022 among 34 key opinion leaders in thoracic surgery from 14 countries worldwide. The 1st round was a brainstorming phase to identify technical procedures that a newly qualified thoracic surgeon should be able to perform. All the suggested procedures were categorized, qualitatively analysed and sent to the 2nd round. The second round investigated: the frequency of the identified procedure at each institution, the number of thoracic surgeons that should be able to perform these procedures, the degree of risk to the patient if the procedure is performed by a non-competent thoracic surgeon and the feasibility of simulation-based education. In the 3rd round, elimination and re-ranking of the procedures from the 2nd round were performed. RESULTS Response rates in the 3 iterative rounds were 80% (28 out of 34), 89% (25 out of 28) and 100% (25 out of 25) in the 1st, 2nd and 3rd round, respectively. Seventeen technical procedures were included for simulation-based training in the final prioritized list. The top 5 procedures were Video-Assisted Thoracoscopic Surgery (VATS) lobectomy, VATS segmentectomy, VATS mediastinal lymph node dissection, diagnostic flexible bronchoscopy and robotic-assisted thoracic surgery port placement, robotic-assisted thoracic surgery docking and undocking. CONCLUSIONS The prioritized list of procedures represents a consensus of key thoracic surgeons worldwide. These procedures are suitable for simulation-based training and should be integrated in the thoracic surgical curriculum., OBJECTIVES: To identify and prioritize technical procedures for simulation-based training to be integrated into the thoracic surgical curriculum.

Introduction: There is a substantial risk of developing stenosis and dysfunction in the arteriovenous fistula (AVF) in patients on hemodialysis (HD). Far infrared radiation (FIR) is a non-invasive local intervention with a potentially beneficial effect on AVF patency. The underlying mechanism is not clear. It was hypothesized that a single FIR treatment reduces factors of inflammation and promotes endothelial vasodilators in the AVF. Methods: Forty HD patients with an AVF were included in an open-label intervention study. Patients were randomized to receive either FIR (FIR group) or no FIR (control group). Blood samples were drawn directly from the AVF and from a peripheral vein in the non-AVF arm before (T0) and 40 min after (T40) treatment during a HD session. The changes [median (interquartile range)] in circulating factors of inflammation, endothelial function and vasoreactivity during FIR were measured. Results: In the AVF a single FIR treatment during dialysis resulted in a significantly diminished decrease in soluble vascular cell adhesion molecule, sVCAM [-31.6 (-54.3; 22.1) vs -89.9 (-121.6; -29.3), P =. 005] and soluble intercellular adhesion molecule, sICAM [-24.2 (-43.5; 25.3) vs -49 (-79.9; -11.6), P =. 02] compared with the control group. Other factors, such as interleukins, nitrite, nitrate and tumor necrosis factor 1, also declined during dialysis, but with no significant differences related to FIR in either the AVF or the non-AVF arm. Conclusion: A single FIR treatment attenuated the decrease in sVCAM and sICAM in the AVF compared with a control group during HD. Findings do not support the hypothesis of a vaso-protective effect of FIR. The long-term effects of FIR on the AVF are unknown.

Since 1976 more than 25,000 Arctic sediment samples have been processed for their palynological, nannofossil, or microfossil content at the Geological Survey of Greenland (GGU) and the Geological Survey of Denmark (DGU); both institutes are now merged into the Geological Survey of Denmark and Greenland (GEUS). The samples represent nearly all ages from the Neoproterozoic to the Neogene, though dominated by the Mesozoic. A large proportion of the samples were processed for palynomorphs. Up to ten slides have been produced for each palynological sample and usually one slide is produced for each nannofossil and microfossil sample, making the GEUS collection one of the largest Arctic slide collections with more than 200,000 slides. All type specimens and some specimens illustrated in publications listed here have been assigned MGUH numbers (Museum Geologica Universitas Hafniensis) and are housed in the type collection of the Geological Museum of the University of Copenhagen, now part of the Natural History Museum of Denmark.

Area regeneration of deprived neighborhoods is being used to reduce health inequality, socioeconomic deprivation and ethnic segregation. This quasi-experimental study examines if long-term graded exposure to urban regeneration is associated with primary healthcare-seeking behavior among residents. We compared general practitioner (GP) contacts from 2015-2020 in two adjacent, deprived social housing areas, one exposed to area regeneration. Populations were into Western and non-Western males and females aged 15 years and older (N = 3,960). Mean annual GP contact frequency for each group were estimated and a difference-in-difference (DiD) analysis was conducted with adjustments for propensity scores based on baseline characteristics. GP contact frequency increased for all groups across time with a systematically higher level and faster increase in the control groups. In particular, the mean difference between the exposed and control area for non-Western women more than doubled from -0.61 to -1.47 annual contacts across the period. The mean differences in contact frequency increased for all groups but results of the DiD analyses were insignificant. In conclusion, an emerging gap in GP contact frequency, with the highest levels in the control area, was observed for all comparisons across time. More long-term research is needed to understand how the emerging gaps evolve.

Introduction: The age and number of comorbidities in the hemodialysis population has increased over time. This may influence the construction and survival of the arteriovenous fistula (AVF). The present study explored the incidence and survival of AVFs over a period of 39 years. Methods: A retrospective cohort study was conducted based on Danish registries. Incident hemodialysis patients between 1977 and 2015 were included. The incidence of AVF and factors associated with the construction of an AVF were described. Risk factors for AVF survival and repair were explored by Kaplan Meier and Cox proportional hazard analysis. Results: The total number of arteriovenous accesses (AVF and arteriovenous grafts) were 10,187 and there were 4201 central venous catheters (CVC). No significant difference in the proportion of AVFs during the 39 years was seen. Age and renal diagnosis did not influence the proportion of AVFs. Patients with CVCs were found to have a significantly higher prevalence of comorbidities (p < 0.01). AVF survival remained stable during the 39 years. The first constructed AVF had the best survival, 35% still functioning after 15 years. Factors such as brachiocephalic AVF, female sex, and diabetic nephropathy increased the risk of AVF failure (Odds Ratio (OR): 2.46, 95% Confidence Interval (CI) (2.29–2.65), 1.17 (1.10–1.25), and 1.21 (1.12–1.3)), respectively. Conclusion: Despite an older dialysis population, the proportion and survival of the AVF in the Danish dialysis population has not changed, probably because of increased awareness of AVF as the first choice of vascular access and improved surveillance, surgery, and repair.
