Abstract
The DeLaval Herd Navigator is an on-farm sensor system that measures on a frequent basis milk progesterone (P4) and β-hydroxybutyrate (BHB) in individual cows to closely monitor reproductive performance and energy balance. This information provides the opportunity to investigate the dynamics of BHB measured in milk (mBHB) and study the association between mBHB and early reproductive performance. The objectives of the study were (1) to describe mBHB dynamics within the first 20 d in milk (DIM), and (2) to evaluate the association between mBHB dynamics and early reproductive performance at cow-level. Two-year time-series data from 4,133 dairy cows in 38 Dutch dairy farms were available for analysis. Data included information on mBHB, daily milk yield and the indicators of early reproductive performance, days from calving to resumption of cyclicity, days from calving to first estrus, and days from calving to first insemination. The following mBHB dynamic parameters were defined based on the first 20 DIM for each individual cow: average mBHB (AvgBHB), DIM when mBHB was for the first time ≥80 μmol/L (OnsetKeto), the total number of consecutive days a cow had mBHB concentration ≥80 μmol/L, and the number of measurements mBHB concentration was ≥80 μmol/L. Three Cox proportional hazard regression models with random herd effect were developed to evaluate the association between cow level mBHB dynamics and days from calving to resumption of cyclicity, first estrus, and first insemination. Results showed that the mean AvgBHB within 20 DIM among all cows was 73 μmol/L. The mean OnsetKeto within 20 DIM, was 8 DIM. Among all cows having hyperketolactia, 55.8% (1,350/2,419) had OnsetKeto in the first week of lactation. In total, 41.5% (1,714/4,133) of the cows did not have OnsetKeto in the first 20 DIM. An early onset of hyperketolactia was associated with delayed fertility events. Cows with higher AvgBHB have a prolonged time interval from calving to resumption of cyclicity and first estrus. Information on mBHB dynamics and the association with early reproductive performance provides insights that might be helpful to improve reproductive performance of individual dairy cows.

Using a digital platform to establish odontometric variation based on race, gender and Angle classification. Orthod Craniofac Res 2023; 26 Suppl 1:204-209. [PMID: 37073633 DOI: 10.1111/ocr.12664] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 03/23/2023] [Accepted: 04/01/2023] [Indexed: 04/20/2023]
Abstract
Orthodontists often encounter significant clinical challenges in the finishing stages of treatment due to a disproportion in interarch tooth size relationships. Despite the increasing presence of digital technology and concomitant focus on customized treatment approaches, there is a gap in the knowledge of how generating tooth size data using digital versus traditional methods may impact our treatment regime. OBJECTIVE This study aimed to compare the prevalence of tooth size discrepancies using digital models and a digitally based cast analysis in our cohort based on (i) Angle's Classification; (ii) gender and (iii) race. MATERIALS AND METHODS The mesiodistal widths of teeth in 101 digital models were assessed using computerized odontometric software. A Chi-square test was used to determine the prevalence of tooth size disproportions among the study groups. The differences between all three groups of the cohort were analysed using a three-way analysis of variance (ANOVA). RESULTS An overall Bolton tooth size discrepancy (TSD) prevalence of 36.6% was observed in our study cohort; 26.7% had an anterior Bolton TSD. No differences existed in the prevalence of tooth size discrepancies between male and female subjects as well as between the different malocclusion groups (P > .05). Caucasian subjects had a statistically significant smaller prevalence of TSD compared to Black and Hispanic patients (P < .05). CONCLUSION The prevalence results in this study illuminate how relatively common TSD is and underscores the importance of proper diagnosis. Our findings also suggest that racial background may be an influential factor in the presence of TSD.

Stress and Health Outcomes in Midwestern Latinx Youth: The Moderating Role of Ethnic Pride. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16966. [PMID: 36554847 PMCID: PMC9779071 DOI: 10.3390/ijerph192416966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 12/13/2022] [Accepted: 12/15/2022] [Indexed: 06/17/2023]
Abstract
BACKGROUND Stress has been linked to numerous health outcomes, including internalizing and externalizing behaviors, self-esteem, and physical health. Culture has also been linked to stress and health. This study examined the links between stress and health, and the potential moderating role of Latinx ethnic pride (LEP). METHODS The sample consisted of 119 Latinx youth from the Midwestern U.S. Mothers and youth completed surveys. Variables included the Multicultural Events Scale for Adolescents (MESA), parent and home stressors/risks (PHSR), LEP, depressive symptoms, aggression, frustration, and self-esteem. Research assistants measured child heights and weights and calculated BMI percentiles. RESULTS LEP was negatively related to MESA, depressive symptoms, aggression, and frustration, and positively related to self-esteem. MESA and PHSR were associated with depressive symptoms, aggression, frustration, and self-esteem, but not with BMI percentile. In adjusted regression analyses, LEP moderated the effects MESA had on frustration and self-esteem, marginally moderated the link between MESA and depressive symptoms, and was not related to aggression or BMI percentile. LEP did not moderate the relationship between PHSR with any health outcomes. CONCLUSIONS Stressors were generally related to child mental health. LEP may play an important role in protecting against some of the effects of stressful events on mental health outcomes.

Nanoscopy and an extended lateral approach can improve the management of latero-central segments in tibial plateau fractures: a cadaveric study. Eur J Trauma Emerg Surg 2022; 49:1433-1439.

Abstract
Abstract
Introduction
The objective of this investigation was to compare different techniques to improve visualization and reduction in tibial plateau fractures involving the central lateral segments.
Methods
Matched pairs of pre-fractured cadaveric tibial plateau fractures that include the central lateral segments were treated by either an anterolateral approach (supine) or PL approach (prone). Reduction was stepwise extended by additional fracturoscopy (FS), nanoscopy (NS) and lastly by epicondyle osteotomy (ECO). Reduction was analyzed by 3D scan and visualization of the lateral plateau was quantified.
Results
Ten specimens (3 pairs 41B3.1, 2 pairs 41C3.3) were analyzed. Fracture steps involving the antero-latero-central (ALC) segment were insufficiently reduced after fluoroscopy using both approaches (AL 2.2 ± 1.2 mm vs PL 2.2 ± 1.0 mm, p 0.95). Additional NS and ECO achieved optimized fracture reduction in the ALC segment (NS AL 1.6 ± 1.3 mm vs PL 0.8 ± 0.9 mm, p 0.32). NS provided visualization of the entire lateral plateau (PL 102.9% ± 7.4, AL 108.8 ± 19.2%), while fracturoscopy only allowed visualization of the ALL segment and partially of PLL and ALC segments (PL 22.0 ± 23.4%, AL 29.7 ± 18.3%).
Conclusion
Optimized reduction of tibial head fractures with involvement of latero-central segments requires additional video-assisted reduction or extended approaches. Nanoscopy helps visualizing of the entire lateral plateau, when compared to fracturoscopy and may become a valuable reduction aid.

Abstract
Abstract
Loneliness is widely acknowledged as a growing public health concern, accelerated by the onset of the COVID-19 pandemic. However, our knowledge about the effectiveness of interventions to reduce loneliness across the lifespan, including knowledge of different intervention strategies, is limited. This preregistered systematic review and meta-analysis aimed to evaluate the effect of interventions to reduce loneliness. The systematic review identified 136 studies. The meta-analysis included 128 studies comprising 54 randomised controlled trials (RCTs) (n = 6,379), 23 multi-cohort studies (n = 2,882) and 48 single-cohort studies (n = 3,009). A small to moderate statistically significant effect was detected (RCTs; SMD = -0.47, multi-cohort studies; SMD = -0.24, single cohort-studies; SMD = -0.42). Using the GRADE system, confidence in the estimates was assessed as low or very low, implying that the estimates may potentially be higher or lower. No statistically significant differences were found between age groups. Psychological treatment, social support interventions, and social and emotional skills training appeared to be the most effective intervention strategies in reducing loneliness but there is currently no strong reason to prefer one intervention strategy over another. Further analyses demonstrated that the long-term effects (i.e., one to six months after the intervention) were comparable to the short-term effects (i.e., up to four weeks after the intervention). Findings from the current meta-analyses provide overall evidence of the effectiveness of loneliness interventions. Given methodological limitations, including the heterogeneity of the reviewed studies, it remains unclear who the interventions would help the most. Overall, there is a need for rigorous and high-quality development and evaluations of interventions for loneliness.
Key messages
• The findings of this meta-analytic review suggest that interventions designed to reduce loneliness are effective.
• Psychological treatment, social support interventions, and social and emotional skills training are the most promising interventions, albeit the magnitude of the effects is moderate.

Abstract
Abstract
Objectives
The present prospective cohort study investigated the association of loneliness and social isolation (SI) with healthcare utilization (HCU) in the general population over time.
Methods
Data from the 2013 Danish “How are you?’ survey (n = 29,472) were combined with individual-level register data from the National Danish Patient Registry and the Danish National Health Service Registry over a 6-year follow-up period (2013-2018). Negative binomial regression analyses were performed while adjusting for baseline demographics and chronic disease.
Results
Loneliness measured at baseline was significantly associated with more GP contacts (incident-rate ratio (IRR) = 1.03, 95% confidence interval (CI) [1.02, 1.04]), more emergency treatments (IRR = 1.06, 95% CI [1.03, 1.10]), more emergency admissions (IRR = 1.06, 95% CI [1.03, 1.06]), and hospital admission days (IRR=1.05, 95% CI [1.00, 1.11]) across the 6-year follow-up period. No significant associations were found between social isolation and HCU with one minor exception, in which SI was associated with fewer planned outpatient treatments (IRR = .97, 95% CI [.94, .99]).
Conclusions
Our findings suggest that loneliness is a risk factor for certain types of HCU, independent of social isolation, baseline demographics, and chronic disease.

Abstract
BackgroundPatients with axial spondyloarthritis (axSpA) in clinical remission tapered Tumor Necrosis Factor inhibitor (TNFi) therapy according to a clinical guideline and had 2 years´ follow-up [1].ObjectivesWe aimed to investigate flare frequency, dose at which flare occurred, type of flare (clinical/ Bath ankylosing spondylitis disease activity index (BASDAI)/magnetic resonance imaging (MRI)) and predictors of flare.MethodsPatients in clinical remission (BASDAI<40, physician global score<40 and without disease activity the previous year) tapered TNFi to 2/3 standard dose at baseline, 1/2 at week (w)16, 1/3 at w32 and 0 (discontinuation) at w48. Patients who flared were increased to previous dose. Predictors of flare at each dose step were investigated by regression analyses.ResultsOf 108 patients, 106 (99%) flared before year 2 (flare occurring mean (SD) 99(44.3) days after last tapering). Twenty-nine patients (27%) flared at 2/3 standard dose, 21 (20%) at 1/2 dose, 29 (27%) at 1/3 dose and 27 (25%) after discontinuation. One-hundred-and-five (99%) had clinical flare, 25 (24%) BASDAI flare and 23 (29% of patients with MRI at flare) MRI flare; and forty-one patients (41%) fulfilled the ASAS-definition of clinically important worsening (≥0.9 increase since baseline) (Figure 1). Most common flare symptoms were back/buttock pain (n=93 (89%)) and pain in peripheral joints/entheseal regions (n=48 (46%)). Higher baseline physician global score was an independent predictor of flare after tapering to 2/3 (Odds ratio=1.19 (95% Confidence Interval=1.05-1.41); p=0.011) (Table 1). Changes in clinical and/or imaging variables in the 16 weeks prior to tapering did not predict flare (data not shown).Table 1.Prediction of flare within 16 weeks after tapering to 2/3 dose (n=74)Values are from timepoint of tapering from full dose to 2/3 doseUnivariate analysesFinal multivariable analyses*OR(95% CI)p-valueOR(95% CI)p-valueMale gender0.96(0.25 - 4.14)0.955Age1.00(0.96 - 1.04)0.880Time since diagnosis1.00(0.95 - 1.06)0.863Current smoker0.70(0.20 - 2.20)0.543HLA-B27 positive0.66(0.18 - 2.41)0.515Previous bDMARDs1.28(0.66 - 2.49)0.458Patient pain VAS1.02(0.98 - 1.06)0.310Physician global VAS1.19(1.04 - 1.41)0.0121.19(1.04 - 1.41)0.011ASDAS1.66(0.70 - 4.10)0.251mNYc positive0.78(0.29 - 2.09)0.615SPARCC SIJ Inflammation Index1.01(0.90 - 1.12)0.861CANDEN Total inflammation0.95(0.65 - 1.25)0.702SPARCC SSS Erosion1.11(0.91 - 1.37)0.293CANDEN Fat0.99(0.96 - 1.02)0.705AUC (95% CI)0.66 (0.54 - 0.78)Predictors were selected by applying backward selection in stacked data. p-values by likelihood ratio tests.

Abstract
A green and optimized protocol has been developed for the preparation of symmetric 1,7-bis(aryl)-1,6-heptadiene-3,5-diones and asymmetric 2-aryl-6-arylidenecyclohexanones with modified substrate scope and good functional group tolerance. Syntheses proceed smoothly under solvent-free conditions, providing moderate to excellent product yields with a minimal workup procedure. Control experiments, spectroscopic, and computational studies support a mechanism involving the boron-assisted in situ generation of imine intermediates. Crystal structures of three curcuminoids and isolated mechanistic intermediates are reported. The data provide insight for the further development of solvent-free protocols toward diverse curcumin derivatives in the fields of pharmaceutical and synthetic chemistries.

Abstract
Rapid advances in the development of sequencing technologies, numbers of commercial providers and diminishing costs have made DNA-based identification and diagnostics increasingly accessible to doctors and laboratories, eliminating the need for local investments in expensive technology and training or hiring of skilled technicians. However, reliable and comparable molecular analyses of bacteria in stool samples are dependent on storage and workflow conditions that do not introduce post-sampling bias, the most important factor being the need to keep the DNA at a stable detectable level. For that reason, there may remain other prohibitively costly requirements for cooling or freezing equipment or special chemical additives. This study investigates the diagnostic detectability of Salmonella and Campylobacter DNA in human, pig and chicken stool samples, stored at different temperatures and with different preservation methods. Stool samples were spiked with 106 CFU/mL of both Salmonella and Campylobacter strains stored at −20 °C, 5 °C and 20 °C (Room temperature, RT) and treated with either RNAlater, EDTA or Silica/ethanol. DNA was extracted at 9 different time points within 30 days and quantified by Qubit (total DNA) and qPCR (Salmonella and Campylobacter DNA). We found no statistically significant differences among the different preservation methods, and DNA from both species was easily detected at all time points and at all temperatures, both with and without preservation. This suggests that infections by these bacteria can be diagnosed and possibly also analysed in further detail simply by taking a stool sample in any suitable sealed container that can be transported to laboratory analysis without special storage or preservation requirements. We briefly discuss how this finding can benefit infection control in both developed and developing countries.

Abstract
BACKGROUND Presence of comorbid diseases at time of cancer diagnosis may affect prognosis. We evaluated the impact of comorbidity on survival of patients diagnosed with renal cell carcinoma (RCC), overall and among younger (<70 years) and older (≥70 years) patients. METHODS We established a nationwide register-based cohort of 7894 patients aged ≥18 years diagnosed with RCC in Denmark between 2006 and 2017. We computed 1- and 5-year overall survival and hazard ratios (HRs) for death according to the Charlson Comorbidity Index (CCI) score. RESULTS Survival decreased with increasing CCI score despite an overall increase in survival over time. The 5-year survival rate of patients with no comorbidity increased from 57% among those diagnosed in 2006-2008 to 69% among those diagnosed in 2012-2014. During the same periods, the survival rate increased from 46% to 62% among patients with a CCI score of 1-2 and from 39% to 44% for those with a CCI score of ≥3. Patients with CCI scores of 1-2 and ≥3 had higher mortality rates than patients with no registered comorbidity (HR 1.15, 95% CI 1.06-1.24 and HR 1.56, 95% CI 1.40-1.73). Patterns were similar for older and younger patients. Particularly, diagnoses of liver disease (HR 2.09, 95% CI 1.53-2.84 and HR 4.01, 95% CI 2.44-6.56) and dementia (HR 2.16, 95% CI 1.34-3.48) increased mortality. CONCLUSION Comorbidity decreased the survival of patients with RCC, irrespective of age, despite an overall increasing survival over time. These results highlight the importance of focusing on comorbidity in this group of patients.

Abstract
Background The impact of remdesivir (RDV) on mortality rates in coronavirus disease 2019 (COVID-19) is controversial, and the mortality effect in subgroups of baseline disease severity has been incompletely explored. The purpose of this study was to assess the association of RDV with mortality rates in patients with COVID-19. Methods In this retrospective cohort study we compared persons receiving RDV with those receiving best supportive care (BSC). Patients hospitalized between 28 February and 28 May 2020 with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 infection were included with the development of COVID-19 pneumonia on chest radiography and hypoxia requiring supplemental oxygen or oxygen saturation ≤94% with room air. The primary outcome was overall survival, assessed with time-dependent Cox proportional hazards regression and multivariable adjustment, including calendar time, baseline patient characteristics, corticosteroid use, and random effects for hospital. Results A total of 1138 patients were enrolled, including 286 who received RDV and 852 treated with BSC, 400 of whom received hydroxychloroquine. Corticosteroids were used in 20.4% of the cohort (12.6% in RDV and 23% in BSC). Comparing persons receiving RDV with those receiving BSC, the hazard ratio (95% confidence interval) for death was 0.46 (.31–.69) in the univariate model (P < .001) and 0.60 (.40–.90) in the risk-adjusted model (P = .01). In the subgroup of persons with baseline use of low-flow oxygen, the hazard ratio (95% confidence interval) for death in RDV compared with BSC was 0.63 (.39–1.00; P = .049). Conclusion Treatment with RDV was associated with lower mortality rates than BSC. These findings remain the same in the subgroup with baseline use of low-flow oxygen.

Background:Few previous studies have investigated the incidence rate (IR) and point prevalence (PP) of seropositive and seronegative rheumatoid arthritis (RA), and further, the estimates remain unknown in the Danish population.Objectives:To investigate the IR and PP of seropositive and seronegative RA in the adult Danish population from 1998 to 2018 using four register-based case definitions of RA.Methods:Nationwide register-based cohort study. Using the Danish administrative registers, patients with RA between 1998 and end of 2018 were identified. ICD-10 codes for RA were identified in the Danish National Patient Registry and information on DMARD prescriptions were obtained through the Danish National Prescription Registry using ATC codes. The used case definitions were1: Criteria A, first time M05/M06 RA diagnosis and redemption of a DMARD in the following year; Criteria B, two RA diagnoses within 90 days of each other, originating from department of rheumatology or general internal medicine, where the latest registered M05/M06 diagnosis defined the serologic status; Criteria C, a M05/M06 diagnosis recorded at any time preceded or followed by redemption of a DMARD prescription within one year, where the M05/M06 diagnosis recorded determined the serologic status; Criteria D, as Criteria A, but with the additional requirements that cases had no registration for other selected inflammatory diseases.In calculation of IRs the total Danish population from 1998 to 2018 was used as reference population for standardisation. The PP was calculated for years 2000, 2009, 2011 and 2018.Results:From 1998 to 2018 the overall IR was 18.0 (95%CI 17.7 to 18.3) per 100,000 person years (PY) for seropositive RA and 16.7 (95%CI 16.4 to 16.9) per 100,000 PY for seronegative RA using Criteria A. A higher IR for seropositive RA than for seronegative RA was found regardless of the case criteria used. Figure 1 shows the temporal IRs of seropositive and seronegative RA.Regardless of case criteria used, the PP increased from 2000 to 2018 for both seropositive and seronegative RA, and the estimates were higher for seropositive RA than for seronegative RA (Table 1).Table 1.Point prevalence of rheumatoid arthritis in Denmark in year 2000, 2009, 2011 and 2018 using four different case definitions2000200920112018SeropositiveSeronegativeSeropositiveSeronegativeSeropositiveSeronegativeSeropositiveSeronegativeCriteria AN3029274174747127871281211243711662Population3964040416629842028914269677PP, % (95%CI)0.08 (0.08 to 0.08)0.07 (0.07 to 0.07)0.18 (0.18 to 0.19)0.17 (0.17 to 0.18)0.21 (0.20 to 0.21)0.19 (0.19 to 0.20)0.27 (0.27 to 0.28)0.26 (0.25 to 0.26)Criteria BN7507489311565903312710100111633413340PP, % (95%CI)0.20 (0.19 to 0.20)0.13 (0.12 to 0.13)0.28 (0.28 to 0.29)0.22 (0.21 to 0.22)0.30 (0.30 to 0.31)0.24 (0.23 to 0.24)0.36 (0.35 to 0.36)0.29 (0.29 to 0.30)Criteria CN6701457011174912512417101491588113712PP, % (95%CI)0.18 (0.17 to 0.18)0.12 (0.12 to 0.12)0.27 (0.27 to 0.28)0.22 (0.22 to 0.23)0.29 (0.29 to 0.30)0.24 (0.24 to 0.25)0.35 (0.34 to 0.35)0.30 (0.30 to 0.31)Criteria DN272423906612598476956759108309452PP, % (95%CI)0.07 (0.07 to 0.07)0.06 (0.06 to 0.07)0.16 (0.16 to 0.16)0.15 (0.14 to 0.15)0.18 (0.18 to 0.19)0.16 (0.16 to 0.17)0.24 (0.23 to 0.24)0.21 (0.20 to 0.21)PP = Point prevalenceConclusion:In Denmark, the IR and PP estimates were higher for seropositive compared to seronegative RA during the study period. However, when applying stricter case criteria for RA (Criteria A and D) the differences in IR and PP estimates were smaller, than when using less strict criteria (Criteria B and C). The findings of such small differences between seropositive and seronegative IRs warrant further investigation.References:[1]Soussi BG et al.

Maternal use of hormonal contraception and epilepsy in offspring. Hum Reprod 2021; 36:1674-1681.

Abstract
STUDY QUESTION Is maternal use of hormonal contraception associated with the development of epilepsy in the offspring? SUMMARY ANSWER We found that maternal use of hormonal contraception was associated with a slightly increased risk of epilepsy in the offspring. WHAT IS KNOWN ALREADY Foetal exposure to exogenous hormones has been associated with changes in brain development. However, little is known about maternal hormonal contraception use and development of epilepsy in the offspring. STUDY DESIGN, SIZE, DURATION A nationwide cohort of all live born children born in Denmark between 1 January 1998 and 31 December 2014, was followed from day 29 after birth for epilepsy (first diagnosis of epilepsy or first redeemed prescription for anti-epileptic medication) to censoring (emigration, death) or 31 December 2015, whichever occurred first. PARTICIPANTS/MATERIALS, SETTING, METHODS Diagnoses of epilepsy were obtained from the National Patient Registry. The Danish National Prescription Registry supplied information on redeemed prescriptions for hormonal contraception and anti-epileptic medication. Maternal hormonal contraception use was categorized as never use (reference group), previous use (prescriptions redeemed >3 months before pregnancy start) and recent use (prescriptions redeemed ≤3 months before or during pregnancy). MAIN RESULTS AND THE ROLE OF CHANCE The data show that 17 585 children developed epilepsy during a median follow-up of 9.2 years (9 732 635 person-years). The hazard ratio (HR) for epilepsy was 1.07 (95% CI 1.02-1.13) in children of mothers who had used any type of hormonal contraception recently, compared with children of mothers who had not used hormonal contraception. The HR was similar for recent use of oral combined products, while the HRs for recent or previous use of non-oral combined products were 1.32 (95% CI 0.98-1.77) and 1.16 (95% CI 1.02-1.32), respectively. For non-oral progestin-only products, the HRs were 1.19 (95% CI 1.04-1.38) and 1.53 (95% CI 1.31-1.80), respectively, for recent and previous use. LIMITATIONS, REASONS FOR CAUTION There may be some misclassification of maternal hormonal contraception use, as some women may not have used the redeemed prescriptions or used them at a different point in time; potentially leading to an attenuation of the estimates. In addition, although we were able to account for known risk factors for epilepsy, unknown or residual confounding cannot be ruled out. WIDER IMPLICATIONS OF THE FINDINGS Our findings are based on nationwide population-based data and can therefore be applied to other similar populations. However, as this is the first study in this field, further studies are needed to confirm our findings. STUDY FUNDING/COMPETING INTEREST(S) No specific funding was obtained for this study, which was supported by internal funding at the Unit of Virus, Lifestyle and Genes. All authors report no conflicts of interest. TRIAL REGISTRATION NUMBER N/A.

Does losing a parent early influence the education you obtain? A nationwide cohort study in Denmark. J Public Health (Oxf) 2020; 41:296-304.

Abstract
BACKGROUND Health inequalities are rooted in education and we investigate the association between early parental death and attainment across the educational spectrum. METHODS Using total population data on Danes born between 1982 and 2000 (n = 1 043 813), we assess incidence rate ratios (RRs) by gender for attainment of each educational level (basic school, high school or vocational training, bachelor degree or professional programme, and university graduate degree) according to loss of a parent before the age of 18 years. We adjust for family income, education and psychiatric illness and examine parent's gender, cause of death and child's age at time of death as potential moderators. RESULTS Bereaved people had significantly lower attainment rates than non-bereaved people: basic school (RR = 0.95; 95% CI: 0.93-0.97 for men and 0.96; 0.94-0.98 for women), high school or vocational training (0.78; 0.76-0.80 for men and 0.82; 0.80-0.84 for women), bachelor degree or professional programme (0.74; 0.70-0.79 for men and 0.83; 0.79-0.86 for women) and university graduate degree (0.77; 0.68-0.86 for men and 0.77; 0.69-0.86 for women). Parent's gender, cause of death and child's age at the death did not modify the associations. CONCLUSIONS As education impacts population health, support for bereaved school children may be more important than realized.

Abstract
Background:The incidence rate (IR) and point prevalence (PP) of rheumatoid arthritis (RA) in Denmark is largely unknown. Two challenges in estimating the “true” IR and PP using nationwide registry data are the choice of the RA case definition, and the denominator used, i.e. the exact amount of person years (PY) or census count data.Objectives:To investigate the incidence and prevalence of RA in the adult Danish population using four different case definitions and two different denominator strategies.Methods:Nationwide register-based cohort study. Patients with RA between 1996 and the end of 2016 were identified using the Danish National Patient Registry (DNPR) and information on DMARD prescriptions were obtained through linkage with the Danish National Prescription Registry. Age and sex standardised incidence and prevalence of RA were calculated in different ways: we estimated the IR (denominator = actual recorded number of PY in each year using migration and vital data) and the incidence proportion (IP) (denominator = census count data); and the PP (%) of RA was calculated for years 2000, 2009, 2011 and 2016. The four case definitions were: Model A, a first time RA diagnosis (ICD-10: M05-06) in DNPR and a redeemed prescription of a conventional DMARD in the following year1; Model B, an RA diagnosis recorded twice in DNPR within 90 days with both records originating from a department of rheumatology or general internal medicine2; Model C, any RA diagnosis recorded in DNPR with a DMARD prescription redeemed in the year before or after the diagnosis; Model D, similar to Model A but with the additional requirement that cases had no registered ICD code for inflammatory diseases prior to the RA diagnosis1.Results:The overall IR of RA from 1996 to 2016 based on model A was 35.2 (95%CI 34.8 to 35.6) per 100,000 PY while the IP was 34.7 (95%CI 34.3 to 35.1) per 100,000 individuals. The age standardised IR was higher for women than for men (Figure 1), and this was observed across all age groups. The IR peaked at age 70 to 74 in both men and women. Regardless of which case definition was used, the temporal trend showed a peak in IR in 2010 followed by a plateau (Figure 2). The overall PP estimate for all four models increased from 2000 to 2016, data shown for Model A in Table 1.Table 1.Point prevalence (PP) of rheumatoid arthritis in years 2000, 2009, 2011 and 2016 based on Model A2000N = 590670.3 % women2009N = 1503770.9 % women2011N = 1736371.0 % women2016N = 2299170.3 % womenPP (%) (95% CI)PP (%) (95% CI)PP (%) (95% CI)PP (%) (95% CI)All0.16 (0.15 to 0.16)0.37 (0.36 to 0.37)0.41 (0.41 to 0.42)0.52 (0.51 to 0.52)Women0.21 (0.20 to 0.22)0.50 (0.49 to 0.51)0.57 (0.56 to 0.58)0.71 (0.70 to 0.72)Men0.10 (0.10 to 0.11)0.23 (0.22 to 0.23)0.25 (0.25 to 0.26)0.32 (0.31 to 0.33)Conclusion:A peak in the IR of RA was observed in 2010, regardless of which case definition was used. We believe this was due to introduction of the new EULAR/ACR diagnostic criteria at that time. IP estimates were systematically lower than IRs calculated using exact migration and vital data as denominator. The PP increased over time regardless of which case definition we used. We conclude that the choice of RA case definition had a larger influence than the choice of denominator.References:[1]inauskas A et al.

Abstract
Background Acute colorectal cancer surgery has been associated with a high postoperative mortality. The primary aim of this study was to examine the association between socioeconomic position and the likelihood of undergoing acute versus elective colorectal cancer surgery. A secondary aim was to determine 1‐year survival among patients treated with acute surgery. Methods All patients who had undergone a surgical procedure according to the Danish Colorectal Cancer Group (DCCG.dk) database, or who were registered with stent or diverting stoma in the National Patient Register from 2007 to 2015, were reviewed. Socioeconomic position was determined by highest attained educational level, income, urbanicity and cohabitation status, obtained from administrative registries. Co‐variables included age, sex, year of surgery, Charlson Co‐morbidity Index score, smoking status, alcohol consumption, BMI, stage and tumour localization. Logistic regression analysis was performed to determine the likelihood of acute colorectal cancer surgery, and Kaplan–Meier and Cox proportional hazards regression methods were used for analysis of 1‐year overall survival. Results In total, 35 661 patients were included; 5310 (14·9 per cent) had acute surgery. Short and medium education in patients younger than 65 years (odds ratio (OR) 1·58, 95 per cent c.i. 1·32 to 1·91, and OR 1·34, 1·15 to 1·55 respectively), low income (OR 1·12, 1·01 to 1·24) and living alone (OR 1·35, 1·26 to 1·46) were associated with acute surgery. Overall, 40·7 per cent of patients died within 1 year of surgery. Short education (hazard ratio (HR) 1·18, 95 per cent c.i. 1·03 to 1·36), low income (HR 1·16, 1·01 to 1·34) and living alone (HR 1·25, 1·13 to 1·38) were associated with reduced 1‐year survival after acute surgery. Conclusion Low socioeconomic position was associated with an increased likelihood of undergoing acute colorectal cancer surgery, and with reduced 1‐year overall survival after acute surgery.

Abstract
BACKGROUND AND PURPOSE AV-1451 (18 F-AV-1451, flortaucipir) positron emission tomography was performed in C9orf72 expansion carriers to assess tau accumulation and disease manifestation. METHODS Nine clinically characterized C9orf72 expansion carriers and 18 age- and gender- matched cognitively normal individuals were psychometrically evaluated and underwent tau positron emission tomography imaging. The regional AV-1451 standard uptake value ratios from multiple brain regions were analyzed. Spearman correlation was performed to relate the AV-1451 standard uptake value ratio to clinical, psychometric and cerebrospinal fluid measures. RESULTS C9orf72 expansion carriers had increased AV-1451 binding in the entorhinal cortex compared to controls. Primary age-related tauopathy was observed postmortem in one patient. AV-1451 uptake did not correlate with clinical severity, disease duration, psychometric performance or cerebrospinal fluid markers. CONCLUSION C9orf72 expansion carriers exhibited increased AV-1451 uptake in entorhinal cortex compared to cognitively normal controls, suggesting a propensity for primary age-related tauopathy. However, AV-1451 accumulation was not associated with psychometric performance in our cohort.

Treatment and Survival From Colorectal Cancer in Denmark, England, Norway, and Sweden: A Population-Based Study. J Glob Oncol 2018.

Abstract
Background: Colorectal cancer (CRC) patients in Denmark and England have historically had worse outcomes than patients diagnosed in other high-income countries with similar healthcare coverage. This survival deficit may be partly explained by differences in stage distribution due to delays in cancer diagnosis, however, differences in stage-specific survival suggest that differences in treatment also explain the survival gap. Aim: We aim to provide a comparison of stage-specific survival of CRC patients diagnosed in Denmark, England, Norway and Sweden, and compare the probability of receiving potentially curative surgery (PCS) by patient and tumor characteristics to understand whether differences in stage and treatment help explain the international differences in survival. Methods: Population-based information on patients aged 18-99 years diagnosed with primary malignant colon or rectal cancer in Denmark, England, Norway, and Sweden during 2010-2012 was extracted from national CRC registries. We compared the prevalence of PCS by stage and age category, and estimated the probability of receiving it using multivariate logistic regression. Age-standardized net survival was estimated using a multivariable modeling approach. Results: There were 13,230 patients diagnosed with CRC in Denmark, 99,869 in England, 11,754 in Norway, and 17,584 in Sweden between 2010 and 2012. The proportion of patients with missing stage information was higher in England than in the other countries. Stage distribution was otherwise similar. Survival of patients with stage I-II tumors was generally comparable between the countries, but lower in England and - to a lesser degree - in Denmark for stage III-IV disease. Patients with unknown stage had lower survival than staged patients in all countries. We found marked disadvantages in the probability of receiving PCS in older patients with stage II-IV disease in England, and stage IV colon cancer patients in Denmark. The proportion of surgically-treated rectal cancer patients (and their survival) was comparable between Denmark, Norway and Sweden for each combination of age group and stage, except for patients diagnosed with stage I disease. The proportion of patients receiving surgery and survival from rectal cancer was generally lower in England. Conclusion: Denmark seems to be catching up with Norway and Sweden, especially in rectal cancer survival. Despite recent improvements, CRC survival in England remains lower than in Sweden and Norway. Survival generally paralleled countries' relative performance in the provision of potentially curative surgery. Differences in patient selection for surgery, especially in older patients and/or with advanced disease, may partly explain the survival deficit. Increases in the proportion treated, in combination with efforts in postoperative care and with other treatment modalities, may translate into better longer-term outcomes, especially for frail patients.

Abstract
The valley can serve as a new degree of freedom in the manipulation of particles or waves in condensed matter physics, whereas systems containing combinations of gain and loss elements constitute rich building units that can mimic non-Hermitian properties. By introducing gain and loss in artificial acoustic boron nitride, we show that the acoustic valley states and the valley-projected edge states display exotic behaviors in that they sustain either attenuated or amplified wave propagation. Our findings show how non-Hermiticity introduces a mechanism in tuning topological protected valley transports, which may have significance in advanced wave control for sensing and communication applications.

Abstract
Disinfection of hatching eggs is essential to ensure high quality production of broilers. Different protocols are followed in different hatcheries; however, only limited scientific evidence on how the disinfection procedures impact the microbiome is available. The aim of the present study was to characterize the microbiome and aerobic bacterial load of hatching eggs before disinfection and during the subsequent disinfection steps. The study included a group of visibly clean and a group of visibly dirty eggs. For dirty eggs, an initial wash in chlorine was performed, hereafter all eggs were submitted to two times fumigation and finally spray disinfection. The eggshell microbiome was characterized by sequencing of the total amount of 16S rRNA extracted from each sample, consisting of shell surface swabs of five eggs from the same group. In addition, the number of colony forming units (cfu) under aerobic conditions was established for each disinfection step. The disinfection procedure reduced the bacterial load from more than 104 cfu (initially visibly clean eggs) and 105 cfu (initially visibly dirty eggs) to less than 10 cfu per sample after disinfection for both groups of eggs. The microbiome of both initially visibly clean and initially visibly dirty eggs had the highest abundances of the phyla Firmicutes, Proteobacteria and Bacteroidetes. Within the phyla Firmicutes the relative abundances of Clostridiales decreased while Lactobacillus increased from before to after final disinfection. In conclusion, the investigated disinfection procedure is effective in reducing the bacterial load, and by adding a chlorine wash for initially visibly dirty eggs, the microbiome of initially visibly clean and initially visibly dirty eggs had a highly similar microflora after the final disinfection step.

Abstract
Background Functional endoscopic sinus surgery has remarkably improved the treatment of chronic rhinosinusitis patients. Computed tomography, endoscopic optical instrumentation, powered microdebriders, and computer-assisted surgery have surmounted the technical problems of obstructive sinusitis care. Most experienced practitioners achieve reported success rates of 85–95% among their surgical patients. However, the 5–15% refractory patients reported by all rhinologic surgeons leave an exasperating and perplexing group who, despite appropriate mechanical corrections, continue to experience debilitating rhinosinusitis episodes requiring repeated oral, nebulized, or intravenous antibiotics, and in some cases, antifungal therapy. Methods Recent studies have indicated that host immune response mechanisms may be altered in the paranasal sinus tissues of sinusitis patients. After years of observation, it was felt that these difficult patients may suffer from a common thread of significant partial immunocompromise. Drawing on military experience of treating immunoimmature populations prone to Epstein-Barr virus (EBV) infectious mononucleosis and the consequent postmononucleosis syndrome, it was sought to screen disabled refractory postsurgical sinusitis patients for this factor and treat them with long-standing military protocols for the immunoimmature populations dispatched to third-world combat conditions. Results Treatment of Epstein-Barr Virus-Mild Acquired Immune Deficiency Syndrome consisted of periodic intramuscular serum immune globulin injections (immunomodulator therapy), after obtaining their thorough written informed consent, which produced substantial and sustainable improvement in patient's quality of life. Conclusion Detection of mild-to-moderate acquired immune deficiency among postsurgical rhinosinusitis patients can lead to successful treatment and an improved quality of life.

Dietary intake of whole grains and plasma alkylresorcinol concentrations in relation to changes in anthropometry: the Danish diet, cancer and health cohort study. Eur J Clin Nutr 2017; 71:944-952. [PMID: 28176776 DOI: 10.1038/ejcn.2016.233] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2016] [Revised: 09/29/2016] [Accepted: 10/19/2016] [Indexed: 02/05/2023]
Abstract
BACKGROUND/OBJECTIVES Whole grain intake has been associated with a small but significant lower body weight gain in observational studies, but there is limited knowledge about the associations with specific whole grain types. The objective was to investigate the association between whole grains, different sources of whole grains and biomarkers of whole grain intake (alkylresorcinols) in relation to subsequent changes in waist circumference (WC) and body weight. SUBJECTS/METHODS Cohort study of 57 053 participants with baseline information on whole grain intake from questionnaires (FFQ) and biomarkers of whole grain rye and wheat intake, plasma alkylresorcinols, for a subset. WC and body weight were measured at baseline and again at follow-up. The associations were estimated using multiple linear regression analyses and logistic regression. RESULTS For women, overall whole grain intake was not related to changes in WC or body weight. For men, total whole grain intake was associated with gains in WC (ΔWC per 25 g increment: 0.44 cm, 95% CI: 0.34 cm; 0.54 cm) and body weight (Δweight per 25 g increment: 150 g, 95% CI: 78 g; 222 g), but the results changed to null or changed direction when adjusting for baseline anthropometry. For the different sources of whole grains, rye (women) and crispbread was significantly associated with gains in WC and body weight. Plasma alkylresorcinol concentration was associated with reduced WC, but not body weight, for women (ΔWC per 50 nmol/l increment: -0.69 cm, 95% CI:-1.26 cm;-0.13 cm), but no association was found for men. CONCLUSIONS Overall, no strong relationship between whole grain intake, measured from questionnaires or using biomarkers was found in relation to changes in body weight and WC.

Prediagnostic enterolactone concentrations and mortality among Danish men diagnosed with prostate cancer. Eur J Clin Nutr 2017; 71:1235-1240. [PMID: 28378849 DOI: 10.1038/ejcn.2017.42] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2016] [Revised: 11/03/2016] [Accepted: 02/28/2017] [Indexed: 11/09/2022]
Abstract
BACKGROUND/OBJECTIVES Evidence on the role of diet in relation to prostate cancer progression is sparse. Foods rich in lignans have shown beneficial effects on prostate cancer progression in both animal studies and small human intervention studies, including beneficial effects on prostate-specific antigen levels and tumour growth. The lignan metabolite, enterolactone, has further shown to slow prostate cancer cell growth in vitro. The aim was to investigate the association between prediagnostic enterolactone concentrations and mortality among men with prostate cancer.Subljects/Methods:Prediagnostic plasma concentrations of enterolactone from 1390 men diagnosed with prostate cancer from the Danish Diet, Cancer and Health cohort were related to all-cause or prostate cancer-specific death, using Cox proportional hazards models with follow-up time (from the date of diagnose until the date of death, emigration or end of follow-up by December 2013) as the underlying time axis. RESULTS The hazard ratios for enterolactone concentrations assessed linearly by 20 nmol/l increments was 0.95 (0.90, 1.02) for all-cause mortality and 0.98 (0.92, 1.05) for prostate cancer-specific mortality. Categorisation of enterolactone concentrations into quartiles did not reveal a different pattern. No effect modifications by smoking, body mass index or sport were observed, and the associations did not differ by prostate cancer aggressiveness. CONCLUSIONS We found no association between enterolactone concentrations and mortality among men diagnosed with prostate cancer.

Detection of Salmonella enterica in Meat in Less than 5 Hours by a Low-Cost and Noncomplex Sample Preparation Method. Appl Environ Microbiol 2017; 83:e03151-16.

Abstract
Salmonella is recognized as one of the most important foodborne bacteria and has wide health and socioeconomic impacts worldwide. Fresh pork meat is one of the main sources of Salmonella, and efficient and fast methods for detection are therefore necessary. Current methods for Salmonella detection in fresh meat usually include >16 h of culture enrichment, in a few cases <12 h, thus requiring at least two working shifts. Here, we report a rapid (<5 h) and high-throughput method for screening of Salmonella in samples from fresh pork meat, consisting of a 3-h enrichment in standard buffered peptone water and a real-time PCR-compatible sample preparation method based on filtration, centrifugation, and enzymatic digestion, followed by fast-cycling real-time PCR detection. The method was validated in an unpaired comparative study against the Nordic Committee on Food Analysis (NMKL) reference culture method 187. Pork meat samples (n = 140) were either artificially contaminated with Salmonella at 0, 1 to 10, or 10 to 100 CFU/25 g of meat or naturally contaminated. Cohen's kappa for the degree of agreement between the rapid method and the reference was 0.64, and the relative accuracy, sensitivity, and specificity for the rapid method were 81.4, 95.1, and 97.9%, respectively. The 50% limit of detections (LOD50s) were 8.8 CFU/25 g for the rapid method and 7.7 CFU/25 g for the reference method. Implementation of this method will enable faster release of Salmonella low-risk meat, providing savings for meat producers, and it will help contribute to improved food safety.IMPORTANCE While the cost of analysis and hands-on time of the presented rapid method were comparable to those of reference culture methods, the fast product release by this method can provide the meat industry with a competitive advantage. Not only will the abattoirs save costs for work hours and cold storage, but consumers and retailers will also benefit from fresher meat with a longer shelf life. Furthermore, the presented sample preparation might be adjusted for application in the detection of other pathogenic bacteria in different sample types.

Biota: Providing often-overlooked connections among freshwater systems. WATER RESOURCES IMPACT 2017; 19:11-13. [PMID: 36959972 PMCID: PMC10032040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 03/25/2023]
Abstract
When we think about connections in and among aquatic systems, we typically envision clear headwater streams flowing into downstream rivers, river floodwaters spilling out onto adjacent floodplains, or groundwater connecting wetlands to lakes and streams. However, there is another layer of connectivity moving materials among freshwater systems, one with connections that are not always tied to down-gradient flows of surface waters and groundwater. These movements are those of organisms, key components of virtually every freshwater system on the planet. In their movements across the landscape, biota connect aquatic systems in often-overlooked ways.

Abstract
Swelling of the submandibular, sublingual and/or parotid glands (“iodide mumps”) is an uncommon complication to intravascular administration of contrast material. The etiology remains unclear, but the reaction seems to be idiosyncratic or related to toxic accumulation of iodide in the ductal systems of the salivary glands. The introduction of nonionic contrast media has not eliminated the risk of developing iodide mumps. The first reported case of iodide mumps after intravascular administration of iopromide (Ultravist 300) is presented.

Abstract
One hundred and thirty-one ultrasound-guided renal biopsies performed in 127 patients with automated spring-loaded biopsy technique were evaluated. Adequate tissue for histologic diagnosis was obtained in 92% of the procedures (94% of the patients). The mean glomerular yield was 16.8 glomeruli. Complications were seen in 21% of the patients, 18% having minor and 3% having major complications. Patients with severe hypertension had significantly more complications than the rest of the patients. The rate of complications in patients who had 3 or 4 biopsy passes was not increased compared to patients who had one or 2 biopsy passes. Thus, this study indicates that the risk of complications and the safety of the procedure is not influenced by increasing the number of biopsy passes in order to obtain representative specimens.

Abstract
Classical systems containing cleverly devised combinations of loss and gain elements constitute extremely rich building units that can mimic non-Hermitian properties, which conventionally are attainable in quantum mechanics only. Parity-time (PT) symmetric media, also referred to as synthetic media, have been devised in many optical systems with the ground breaking potential to create nonreciprocal structures and one-way cloaks of invisibility. Here we demonstrate a feasible approach for the case of sound where the most important ingredients within synthetic materials, loss and gain, are achieved through electrically biased piezoelectric semiconductors. We study first how wave attenuation and amplification can be tuned, and when combined, can give rise to a phononic PT synthetic media with unidirectional suppressed reflectance, a feature directly applicable to evading sonar detection.

Abstract
In July 2013, a resident of the Bitterroot Valley in western Montana, USA, contracted tickborne relapsing fever caused by an infection with the spirochete Borrelia hermsii. The patient's travel history and activities before onset of illness indicated a possible exposure on his residential property on the eastern side of the valley. An onsite investigation of the potential exposure site found the vector, Ornithodoros hermsi ticks, and 1 chipmunk infected with spirochetes, which on the basis of multilocus sequence typing were identical to the spirochete isolated from the patient. Field studies in other locations found additional serologic evidence and an infected tick that demonstrated a wider distribution of spirochetes circulating among the small mammal populations. Our study demonstrates that this area of Montana represents a previously unrecognized focus of relapsing fever and poses a risk for persons of acquiring this tickborne disease.
