A systematic evaluation of seven different scores representing the EAT-Lancet reference diet and mortality, stroke, and greenhouse gas emissions in three cohorts.

Different approaches have been used for translation of the EAT-Lancet reference diet into dietary scores that can be used to assess health and environmental impact. Our aim was to compare the different EAT-Lancet diet scores, and to estimate their associations with all-cause mortality, stroke incidence, and greenhouse gas emissions. We did a systematic review (PROSPERO, CRD42021286597) to identify different scores representing adherence to the EAT-Lancet reference diet. We then qualitatively compared the diet adherence scores, including their ability to group individuals according the EAT-Lancet reference diet recommendations, and quantitatively assessed the associations of the diet scores with health and environmental outcome data in three diverse cohorts: the Danish Diet, Cancer and Health Cohort (DCH; n=52 452), the Swedish Malmö Diet and Cancer Cohort (MDC; n=20 973), and the Mexican Teachers' Cohort (MTC; n=30 151). The DCH and MTC used food frequency questionnaires and the MDC used a modified diet history method to assess dietary intake, which we used to compute EAT-Lancet diet scores and evaluate the associations of scores with hazard of all-cause mortality and stroke. In the MDC, dietary greenhouse gas emission values were summarised for every participant, which we used to predict greenhouse gas emissions associated with varying diet adherence scores on each scoring system. In our review, seven diet scores were identified (Knuppel et al, 2019; Trijsburg et al, 2020; Cacau et al, 2021; Hanley-Cook et al, 2021; Kesse-Guyot et al, 2021; Stubbendorff et al, 2022; and Colizzi et al, 2023). Two of the seven scores (Stubbendorff and Colizzi) were among the most consistent in grouping participants according to the EAT-Lancet reference diet recommendations across cohorts, and higher scores (greater diet adherence) were associated with decreased risk of mortality (in the DCH and MDC), decreased risk of incident stroke (in the DCH and MDC for the Stubbendorff score; and in the DCH for the Colizzi score), and decreased predicted greenhouse gas emissions in the MDC. We conclude that the seven different scores representing the EAT-Lancet reference diet had differences in construction, interpretation, and relation to disease and climate-related outcomes. Two scores generally performed well in our evaluation. Future studies should carefully consider which diet score to use and preferably use multiple scores to assess the robustness of estimations, given that public health and environmental policy rely on these estimates.

Epidemiology of Renal Replacement Therapy for Critically Ill Patients across Seven Health Jurisdictions.

INTRODUCTION: Acute kidney injury (AKI) requiring treatment with renal replacement therapy (RRT) is a common complication after admission to an intensive care unit (ICU) and is associated with significant morbidity and mortality. However, the prevalence of RRT use and the associated outcomes in critically patients across the globe are not well described. Therefore, we describe the epidemiology and outcomes of patients receiving RRT for AKI in ICUs across several large health system jurisdictions. METHODS: Retrospective cohort analysis using nationally representative and comparable databases from seven health jurisdictions in Australia, Brazil, Canada, Denmark, New Zealand, Scotland, and the USA between 2006 and 2023, depending on data availability of each dataset. Patients with a history of end-stage kidney disease receiving chronic RRT and patients with a history of renal transplant were excluded. RESULTS: A total of 4,104,480 patients in the ICU cohort and 3,520,516 patients in the mechanical ventilation cohort were included. Overall, 156,403 (3.8%) patients in the ICU cohort and 240,824 (6.8%) patients in the mechanical ventilation cohort were treated with RRT for AKI. In the ICU cohort, the proportion of patients treated with RRT was lowest in Australia and Brazil (3.3%) and highest in Scotland (9.2%). The in-hospital mortality for critically ill patients treated with RRT was almost fourfold higher (57.1%) than those not receiving RRT (16.8%). The mortality of patients treated with RRT varied across the health jurisdictions from 37 to 65%. CONCLUSION: The outcomes of patients who receive RRT in ICUs throughout the world vary widely. Our research suggests that differences in access to and provision of this therapy are contributing factors.

Use of Latent Class Analysis to Predict Intensive Care Unit Admission and Mortality in Children with a Major Congenital Anomaly.

OBJECTIVE: To define major congenital anomaly (CA) subgroups and assess outcome variability based on defined subgroups. STUDY DESIGN: This population-based cohort study used registries in Denmark for children born with a major CA between January 1997 and December 2016, with follow-up until December 2018. We performed a latent class analysis (LCA) using child and family clinical and sociodemographic characteristics present at birth, incorporating additional variables occurring until age of 24 months. Cox proportional hazards regression models estimated hazard ratios (HRs) of pediatric mortality and intensive care unit (ICU) admissions for identified LCA classes. RESULTS: The study included 27 192 children born with a major CA. Twelve variables led to a 4-class solution (entropy = 0.74): (1) children born with higher income and fewer comorbidities (55.4%), (2) children born to young mothers with lower income (24.8%), (3) children born prematurely (10.0%), and (4) children with multiorgan involvement and developmental disability (9.8%). Compared with those in Class 1, mortality and ICU admissions were highest in Class 4 (HR = 8.9, 95% CI = 6.4-12.6 and HR = 4.1, 95% CI = 3.6-4.7, respectively). More modest increases were observed among the other classes for mortality and ICU admissions (Class 2: HR = 1.7, 95% CI = 1.1-2.5 and HR = 1.3, 95% CI = 1.1-1.4, respectively; Class 3: HR = 2.5, 95% CI = 1.5-4.2 and HR = 1.5, 95% CI = 1.3-1.9, respectively). CONCLUSIONS: Children with a major CA can be categorized into meaningful subgroups with good discriminative ability. These groupings may be useful for risk-stratification in outcome studies.

Community composition of the entomopathogenic fungal genus Metarhizium in soils of tropical and temperate conventional and organic strawberry fields.

Studies on community composition and population structure of entomopathogenic fungi are imperative to link ecosystem functions to conservation biological control. We studied the diversity and abundance of Metarhizium spp. from soil of conventionally and organically farmed strawberry crops and from the adjacent field margins in two different climatic zones: Brazil (tropical) and Denmark (temperate), using the same isolating methods. In Brazilian strawberry soil, Metarhizium robertsii (n = 129 isolates) was the most abundant species, followed by M. humberi (n = 16); M. anisopliae (n = 6); one new taxonomically unassigned lineage Metarhizium sp. indet. 5 (n = 4); M. pingshaense (n = 1) and M. brunneum (n = 1). In Denmark, species composition was very different, with M. brunneum (n = 33) being isolated most commonly, followed by M. flavoviride (n = 6) and M. pemphigi (n = 5), described for the first time in Denmark. In total, 17 haplotypes were determined based on MzFG543igs sequences, four representing Danish isolates and 13 representing Brazilian isolates. No overall difference between the two climatic regimes was detected regarding the abundance of Metarhizium spp. in the soil in strawberry fields and the field margins. However, we found a higher Shannon's diversity index in organically managed soils, confirming a more diverse Metarhizium community than in soils of conventionally managed agroecosystems in both countries. These findings contribute to the knowledge of the indigenous diversity of Metarhizium in agricultural field margins with the potential to contribute to pest regulation in strawberry cropping systems.

Societal costs and survival of patients with biopsy-verified non-alcoholic steatohepatitis: Danish nationwide register-based study.

INTRODUCTION AND OBJECTIVES: Studies on the societal burden of patients with biopsy-confirmed non-alcoholic fatty liver disease (NAFLD) are sparse. This study examined this question, comparing NAFLD with matched reference groups. MATERIALS AND METHODS: Nationwide Danish healthcare registers were used to include all patients (≥18 years) diagnosed with biopsy-verified NAFLD (1997-2021). Patients were classified as having simple steatosis or non-alcoholic steatohepatitis (NASH) with or without cirrhosis, and all matched with liver-disease free reference groups. Healthcare costs and labour market outcomes were compared from 5 years before to 11 years after diagnosis. Patients were followed for 25 years to analyse risk of disability insurance and death. RESULTS: 3,712 patients with biopsy-verified NASH (n = 1,030), simple steatosis (n = 1,540) or cirrhosis (n = 1,142) were identified. The average total costs in the year leading up to diagnosis was 4.1-fold higher for NASH patients than the reference group (EUR 6,318), 6.2-fold higher for cirrhosis patients and 3.1-fold higher for simple steatosis patients. In NASH, outpatient hospital contacts were responsible for 49 % of the excess costs (EUR 3,121). NASH patients had statistically significantly lower income than their reference group as early as five years before diagnosis until nine years after diagnosis, and markedly higher risk of becoming disability insurance recipients (HR: 4.37; 95 % CI: 3.17-6.02) and of death (HR: 2.42; 95 % CI: 1.80-3.25). CONCLUSIONS: NASH, simple steatosis and cirrhosis are all associated with substantial costs for the individual and the society with excess healthcare costs and poorer labour market outcomes.

Socio-cognitive barriers to healthy eating among mothers: A segmentation analysis in Argentina, France, and Denmark.

The prevalence of childhood obesity has increased at an alarming rate despite several actions to reverse this trend. It is important to focus on tackling the constraints for healthy food provisioning. We focus on identifying segments of mothers in relation to factors acting as barriers to healthy eating. Five hundred mothers in each country (Argentina, France and Denmark) completed an online survey. In each of the three countries, four segments are identified, varying mostly on working and socio-economic status, self-efficacy and attitudes to health experts. Segments of mothers who are skeptical to nutrition advice from health professionals were identified. Another important finding is that staying-at-home mothers might face more barriers to healthy eating than mothers who work outside the home. We provide suggestions for targeted interventions addressing healthy eating behaviors among mothers with different profiles.

Inquiry in psychology.

When they discuss the Danish academic situation, Szulevicz, Lund and Lund (2021) address three questions about the academic training of psychology researchers: (a) why do Danish master's students in psychology more frequently choose the qualitative method for their research?; (b) what are psychology students working on?; and (c) what are they interested in? These three questions have led us to reflect on researcher training and the political and educational model universities adopt for psychology master's courses, not only in the Danish context, but also in other general contexts. In this commentary, we will discuss one strictly normative issue: what should the scientific ideal be for training researchers in psychology? Or more accurately: how can psychology contribute to discussions about the scientific ideal of researcher training in this knowledge area?

Musculoskeletal Diagnoses before Cancer in Children: A Danish Registry-Based Cohort Study.

OBJECTIVE: To identify the prevalence of musculoskeletal diagnoses recorded 6 months before the diagnosis of cancer and to evaluate whether preceding musculoskeletal diagnoses affected survival. STUDY DESIGN: We performed a nationwide registry-based cohort study including all children under 15 years of age diagnosed with cancer in Denmark over a 23-year period (1996-2018). The Danish National Patient Registry was used to identify musculoskeletal diagnoses and associated dates recorded within 6 months preceding the diagnosis of cancer. We compared the characteristics of children with and without a prior musculoskeletal diagnoses using prevalence ratios and 95% CI and diagnostic interval as median with IQR. We compared survival using Kaplan-Meier and Cox proportional hazards regression analysis adjusting for age, sex, and presence of metastasis at diagnosis. RESULTS: Of 3895 children with all types of cancer, 264 (7%) had a total of 451 hospital visits with musculoskeletal diagnosis within 6 months preceding the diagnosis of cancer; however, survival was not affected. The overall median diagnostic interval from first musculoskeletal diagnosis (within 6 months before cancer diagnosis) to cancer diagnosis was 15 days (IQR, 7-47 days). A diagnosis of juvenile idiopathic arthritis, unspecified arthritis, and arthropathy each accounted for 5% of the contacts, primarily in children with acute lymphoblastic leukemia, bone sarcomas, or neuroblastomas. CONCLUSIONS: A preliminary musculoskeletal diagnosis occurred in 7% of children with cancer, but did not affect the overall survival.

SARS-CoV-2 genomics: An Indian perspective on sequencing viral variants.

Since its emergence as a pneumonia-like outbreak in the Chinese city of Wuhan in late 2019, the novel coronavirus disease COVID-19 has spread widely to become a global pandemic. The first case of COVID-19 in India was reported on 30 January 2020 and since then it has affected more than ten million people and resulted in around 150,000 deaths in the country. Over time, the viral genome has accumulated mutations as it passes through its human hosts, a common evolutionary mechanism found in all microorganisms. This has implications for disease surveillance and management, vaccines and therapeutics, and the emergence of reinfections. Sequencing the viral genome can help monitor these changes and provides an extraordinary opportunity to understand the genetic epidemiology and evolution of the virus as well as tracking its spread in a population. Here we review the past year in the context of the phylogenetic analysis of variants isolated over the course of the pandemic in India and highlight the importance of continued sequencing-based surveillance in the country.

Congenital Heart Defects and the Risk of Spontaneous Preterm Birth.

OBJECTIVES: To estimate the association between major types of congenital heart defects (CHD) and spontaneous preterm birth, and to assess the potential underlying mechanisms. STUDY DESIGN: This nationwide, registry-based study included a cohort of all singleton pregnancies in Denmark from 1997 to 2013. The association between CHD and spontaneous preterm birth was estimated by multivariable Cox regression, adjusted for potential confounders. The following potential mechanisms were examined: maternal genetics (sibling analyses), polyhydramnios, preterm prelabor rupture of membranes, preeclampsia, and indicators of fetal and placental growth. RESULTS: The study included 1 040 474 births. Compared with the general population, CHD was associated with an increased risk of spontaneous preterm birth, adjusted hazard ratio 2.1 (95% CI, 1.9-2.4). Several subtypes were associated with increased risks, including pulmonary stenosis combined with a septal defect, 5.2 (95% CI, 3.7-7.5); pulmonary stenosis or atresia, 3.1 (95% CI, 2.4-4.1); tetralogy of Fallot 2.5 (95% CI, 1.6-3.8); coarctation or interrupted aortic arch 2.2 (95% CI, 1.5-3.2); and hypoplastic left heart syndrome, 2.0 (95% CI, 1.0-4.1). Overall, preterm prelabor rupture of membranes mediated more than one-half of the association. Maternal genetics, polyhydramnios, or indicators of fetal or placental growth did not explain the reported associations. CONCLUSIONS: CHD, especially right ventricular outflow tract obstructions, were associated with an increased risk of spontaneous preterm birth. The risk was carried by the CHD and not by maternal genetics. Moreover, preterm prelabor rupture of membranes was identified as a potential underlying mechanism.

Polygenic Risk and Progression to Bipolar or Psychotic Disorders Among Individuals Diagnosed With Unipolar Depression in Early Life.

OBJECTIVE: The authors investigated the associations between polygenic liability and progression to bipolar disorder or psychotic disorders among individuals diagnosed with unipolar depression in early life. METHODS: A cohort comprising 16,949 individuals (69% female, 10-35 years old at the first depression diagnosis) from the iPSYCH Danish case-cohort study (iPSYCH2012) who were diagnosed with depression in Danish psychiatric hospitals from 1994 to 2016 was examined. Polygenic risk scores (PRSs) for major depression, bipolar disorder, and schizophrenia were generated using the most recent results from the Psychiatric Genomics Consortium. Hazard ratios for each disorder-specific PRS were estimated using Cox regressions with adjustment for the other two PRSs. Absolute risk of progression was estimated using the cumulative hazard. RESULTS: Patients were followed for up to 21 years (median=7 years, interquartile range, 5-10 years). The absolute risks of progression to bipolar disorder and psychotic disorders were 7.3% and 13.8%, respectively. After mutual adjustment for the other PRSs, only the PRS for bipolar disorder predicted progression to bipolar disorder (adjusted hazard ratio for a one-standard-deviation increase in PRS=1.11, 95% CI=1.03, 1.21), and only the PRS for schizophrenia predicted progression to psychotic disorders (adjusted hazard ratio=1.10, 95% CI=1.04, 1.16). After adjusting for PRSs, parental history still strongly predicted progression to bipolar disorder (adjusted hazard ratio=5.02, 95% CI=3.53, 7.14) and psychotic disorders (adjusted hazard ratio=1.63, 95% CI=1.30, 2.06). CONCLUSIONS: PRSs for bipolar disorder and schizophrenia are associated with risk for progression to bipolar disorder or psychotic disorders, respectively, among individuals diagnosed with depression; however, the effects are small compared with parental history, particularly for bipolar disorder.

Host age predicts parasite occurrence, richness, and nested infracommunities in a pilot whale-helminth network.

Ecological data on marine mammal parasites represent an excellent opportunity to expand our understanding of host-parasite systems. In this study, we used a dataset of intestinal helminth parasites on 167 long-finned pilot whales Globicephala melas (Traill, 1809) from seven localities in the Faroe Islands to evaluate the extent to which the host's age and sex influence the occurrence, richness, and nested pattern of helminth parasites and the importance of individual hosts to the helminth community. We found positive effects of age on both the occurrence and richness of helminths. Older host individuals showed an ordered accumulation of parasites, as evidenced by the nested pattern in their composition. Males had a higher occurrence of parasites than females, but the richness of helminths did not differ between sexes. Our findings suggest that differences in host-parasite interactions in long-finned pilot whales result mainly from age-structured variations in biological and behavioral characteristics.

Reabertura de escolas pós-pandemia / Reopening of pandemic schools

Considerando que Organização Mundial de Saúde (OMS) orienta que os tomadores de decisão devem considerar, três questões como: o entendimento atual sobre transmissão e gravidade do COVID-19 em crianças, situação local e epidemiologia do COVID-19 onde estão localizadas as escolas e configuração escolar e capacidade de manter medidas de prevenção e controle do COVID-19. Faz uma avaliação sobre as experiências de retorno às aulas ocorridas na China, Coreia do Sul, Dinamarca, Noruega, Alemanha, França, Grécia, Portugal, Canadá, Holanda, Croácia e Sérvia, Reino Unido, Espanha e Itália e Suécia, conclui que não foram localizadas informações oficiais quanto ao impacto das medidas de reabertura das escolas, todavia, diversos países já evoluíram para fases seguintes dos seus planos, o que leva a considerar que as etapas iniciais evoluíram conforme o esperado. Apesar da variedade de racionais adotados pelos tomadores de decisão nos diferentes países, é nítido em todas as experiências o alto nível de planejamento e rigor das regras estabelecidas, também a importância da colaboração e participação dos envolvidos (famílias, estudantes e equipe de ensino). Aponta que as desigualdades das condições das escolas, e também a preocupação com as desigualdades do ensino frente os exames nacionais e a grande variabilidade socioeconômica brasileira como um aspecto a ser analisado pelas autoridades do ensino do estado de Goiás e do Brasil

Considering that the World Health Organization (WHO) advises that decision makers should consider three issues such as: the current understanding of COVID-19 transmission and severity in children, the local situation and epidemiology of COVID-19 where schools are located and school configuration and ability to maintain COVID-19 prevention and control measures. Evaluates the experiences of return to school in China, South Korea, Denmark, Norway, Germany, France, Greece, Portugal, Canada, the Netherlands, Croatia and Serbia, the United Kingdom, Spain and Italy and Sweden, concludes that it does not official information was found on the impact of school reopening measures, however, several countries have already moved on to the next stages of their plans, which leads to the conclusion that the initial stages have evolved as expected. Despite the variety of rationales adopted by decision makers in different countries, the high level of planning and rigor of the established rules is clear in all experiences, as well as the importance of collaboration and participation of those involved (families, students and teaching staff). It points out that inequalities in the conditions of schools, and also the concern with inequalities in teaching in the face of national exams and the great Brazilian socioeconomic variability as an aspect to be analyzed by the education authorities of the state of Goiás and Brazil

Recurrence of Cholesteatoma: A Retrospective Study Including 1006 Patients for More than 33 Years

Abstract Introduction Cholesteatomas are benign tumors consisting of skin, and growing inside a retraction pocket in the tympanic membrane. Cholesteatomas can occupy the entirety of the middle ear, and are known for their osteolytic capabilities. Surgery is the only curative treatment for cholesteatomas. Objective To describe the risk of recurrence after first-time surgically-treated middle- ear cholesteatoma (STMEC1) on the island of Funen from 1983 to 2015. Methods Cases of STMEC1 were identified in the Danish National Hospital Register. The medical records were reviewed. Time-to-event analyses were applied. The ears were followed from STMEC1 to a secondary cholesteatoma, emigration, death, or end of follow-up. Results Records from 1,006 patients with STMEC1 were reviewed. A total of 54 patients were submitted to surgery on both ears. The total sample consisted of 1,060 ears with STMEC1; 300 were children's (< 16 years) ears, and 760 were adult's ears. The total observation time was of 12,049 years. The overall estimated proportion with recurrence 5 years after surgery was of 37% in children and of 15% in adults. The older the child was at the first surgery, the risk decreased by 7% per year. In children, canal wall up (CWU) mastoidectomy without obliteration was associated with a hazard ratio for recurrence of 1.9 (95% confidence interval [95%CI]: 1.2-3.0) compared with CWU with obliteration. Conclusion Compared with adults, children were had 2.6 times more risk of recurrence. Procedures performed without mastoidectomy had the lowest risk of recurrence. In children, obliteration was associated with a significantly lower risk of recurrence. However, patients were not randomized regarding the surgical approach; thus, the association between approach and risk of recurrence was likely influenced by confounding factors.
