Abstract
OBJECTIVE Examine the independent associations and interaction between early-life adversity and residential ambient air pollution exposure on relative buccal telomere length (rBTL). METHODS Experiences of abuse, neglect, household challenges, and related life events were identified in a cross-sectional sample of children ages 1-11 years (n = 197) using the 17-item Pediatric ACEs and Related Life Event Screener (PEARLS) tool. The PEARLS tool was analyzed both as a total score and across established domains (Maltreatment, Household Challenges, and Social Context). Ground-level fine particulate matter (PM 2.5 ) concentrations were matched to residential locations for the one and twelve months prior to biospecimen collection. We used multivariable linear regression models to examine for independent associations between continuous PM 2.5 exposure and PEARLS score/domains with rBTL. Additionally, effect modification by PEARLS scores and domains on associations between PM 2.5 exposure and rBTL was examined. RESULTS Study participants were 47% girls, with mean age = 5.9 years [standard deviation: 3.4] median reported PEARLS score of 2 [interquartile range (IQR): 4], median 12-month prior PM 2.5 concentrations of 11.8 μg/m 3 [IQR: 2.7], median 1-month prior PM 2.5 concentrations of 10.9 μg/m 3 [IQR: 5.8], and rBTL of 0.1 [IQR: 0.03]. Mean 12-month prior PM 2.5 exposure was inversely associated with rBTL (ß = -0.02, 95% CI: -0.04, -0.01). While reported PEARLS scores and domains were not independently associated with rBTL, we observed a greater decrement in rBTL with increment of average annual PM 2.5 as reported Social Context domain items increased (p-interaction<0.05). CONCLUSION Our results suggest that adverse Social Context factors may accelerate the association between chronic PM 2.5 exposure on telomere shortening during childhood.

Abstract
INTRODUCTION Social media (SoMe) is widely used as a communication platform in everyday life. Also, healthcare professionals have embraced SoMe as a communication tool for both peers and patients. It is becoming an interactive tool for discussing professionals' issues and a place where learning and education occur. This study explores the specific patterns of SoMe use for radiographers' in the Nordic countries. The aim of this survey was to investigate radiographers use of social platforms in a professional setting. METHODS A 29-item survey was prepared, and pilot-tested. The survey was produced in Danish a language that all Nordic countries master. In general, most Nordic languages are very similar. The survey was distributed by online platforms such as Facebook, LinkedIn, Twitter/X, and also distributed by newsletters by the Norwegian and Danish national radiographers societies. All data was collected anonymously. An Ethical Research approval was obtained from the University of Southern Denmark. RESULTS A total of 242 respondents completed the survey (Denmark n = 183, Norway n = 48, Sweden n = 8, and n = 3 from other Scandinavian countries). The respondents included 186 females, 52 males and four were undisclosed. On average, the respondents spent approximately 2 h and 23 min daily on SoMe, with 27 min specifically dedicated to content relevant to radiographers. Facebook was the preferred platform with 93 % (n = 226). A total of 5.4 % (n = 13) respondents had experienced contact from patients and/or next of kin, while 92 % (n = 222) reported no such interactions and 2.9 % (n = 7) were undisclosed. A total of 52.8 % (n = 128) used SoMe in relation to courses, conferences, or online meetings. This shows that time spent on content relevant to radiographers imply that SoMe can be a relevant tool for reaching radiographers. CONCLUSION The survey demonstrates radiographers' use of SoMe for personal and professional interest, with Facebook as the preferred social media platform. SoMe were mostly used during courses, conferences, or online meetings with half of the respondent reported using SoMe platforms during working hours. These results underscore the untapped potential of SoMe in professional healthcare settings. Additionally, the study offers insight into current practices, facilitating comparisons to identify trends in SoMe usage within the radiographer community. IMPLICATIONS FOR PRACTICE The findings advocate for the strategic use of SoMe by radiographers', emphasizing professional networking and knowledge sharing. However, clear guidelines are necessary to ensure patient confidentiality and data security in these digital interactions.

Abstract
BACKGROUND Wildfire smoke exposure has become a growing public health concern, as megafires and fires at the wildland urban interface increase in incidence and severity. Smoke contains many pollutants that negatively impact health and is linked to a number of health complications and chronic diseases. Communicating effectively with the public, especially at-risk populations, to reduce their exposure to this environmental pollutant has become a public health priority. Although wildfire smoke risk communication research has also increased in the past decade, best practice guidance is limited, and most health communications do not adhere to health literacy principles: readability, accessibility, and actionability. This scoping review identifies peer-reviewed studies about wildfire smoke risk communications to identify gaps in research and evaluation of communications and programs that seek to educate the public. METHODS Four hundred fifty-one articles were identified from Web of Science and PubMed databases. After screening, 21 articles were included in the final sample for the abstraction process and qualitative thematic analysis. Ten articles were based in the US, with the other half in Australia, Canada, Italy, and other countries. Fifteen articles examined communication materials and messaging recommendations. Eight papers described communication delivery strategies. Eleven articles discussed behavior change. Six articles touched on risk communications for vulnerable populations; findings were limited and called for increasing awareness and prioritizing risk communications for at-risk populations. RESULTS This scoping review found limited studies describing behavior change to reduce wildfire smoke exposure, characteristics of effective communication materials and messaging, and communication delivery strategies. Literature on risk communications, dissemination, and behavior change for vulnerable populations was even more limited. CONCLUSIONS Recommendations include providing risk communications that are easy-to-understand and adapted to specific needs of at-risk groups. Communications should provide a limited number of messages that include specific actions for avoiding smoke exposure. Effective communications should use mixed media formats and a wide variety of dissemination strategies. There is a pressing need for more intervention research and effectiveness evaluation of risk communications about wildfire smoke exposure, and more development and dissemination of risk communications for both the general public and vulnerable populations.

Abstract
Interactions between plants and herbivores are central in most ecosystems, but their strength is highly variable. The amount of variability within a system is thought to influence most aspects of plant-herbivore biology, from ecological stability to plant defense evolution. Our understanding of what influences variability, however, is limited by sparse data. We collected standardized surveys of herbivory for 503 plant species at 790 sites across 116° of latitude. With these data, we show that within-population variability in herbivory increases with latitude, decreases with plant size, and is phylogenetically structured. Differences in the magnitude of variability are thus central to how plant-herbivore biology varies across macroscale gradients. We argue that increased focus on interaction variability will advance understanding of patterns of life on Earth.

Abstract
To examine whether fasting plasma liver-expressed antimicrobial peptide 2 (FP-LEAP2) is associated with markers of cardiometabolic disease susceptibility in a cohort with prediabetes and overweight/obesity and whether antidiabetic interventions affect FP-LEAP2 levels. The analysis included 115 individuals with prediabetes [hemoglobin A1c (HbA1c) 39-47 mmol/mol, 5.7%-6.4%] and overweight/obesity [body mass index (BMI) ≥ 25 kg/m2] from a randomized controlled trial. Changes in FP-LEAP2 levels were assessed in relation to treatment with dapagliflozin (10 mg once daily), metformin (1,700 mg daily), or interval-based exercise (5 days/wk, 30 min/session) compared with control (habitual lifestyle) after 6 and 13 wk of treatment. FP-LEAP2 levels were positively associated with [standardized beta coefficient (95% CI)]: BMI 0.22 (0.03:0.41), P = 0.027; body weight 0.27 (0.06:0.48), P = 0.013; fat mass 0.2 (0.00:0.4), P = 0.048; lean mass 0.47 (0.13:0.8), P = 0.008; HbA1c 0.35 (0.17:0.53), P < 0.001; fasting plasma glucose (FPG) 0.32 (0.12:0.51), P = 0.001; fasting serum insulin 0.28 (0.09:0.47), P = 0.005; total cholesterol 0.19 (0.01:0.38), P = 0.043; triglycerides 0.31 (0.13:0.5), P < 0.001; and transaminases and fatty liver index (standardized beta coefficients 0.23-0.32), all P < 0.020. FP-LEAP2 levels were inversely associated with insulin sensitivity [-0.22 (-0.41: -0.03), P = 0.022] and kidney function [estimated glomerular filtration rate (eGFR) -0.34 (-0.56: -0.12), P = 0.003]. FP-LEAP2 levels were not associated with fat distribution or body fat percentage, fasting glucagon, postload glucose, β-cell function, or low-density lipoprotein. The interventions were not associated with changes in FP-LEAP2. FP-LEAP2 is associated with body mass, impaired insulin sensitivity, liver-specific enzymes, and kidney function. The findings highlight the importance of studying LEAP2 in obesity, type 2 diabetes, and nonalcoholic fatty liver disease. FP-LEAP2 was not affected by metformin, dapaglifloxin, or exercise in this population.NEW & NOTEWORTHY LEAP2, primarily secreted by the liver, increases with greater body mass, insulin resistance, and liver-specific enzymes in individuals with prediabetes and overweight or obesity. Fasting glucose, body mass, and alanine aminotransferase independently predict LEAP2 levels. LEAP2 is inversely linked to impaired kidney function. Elevated LEAP2 levels might indicate an increased metabolic risk, warranting further investigation into its potential involvement in glucose and body weight control.

Abstract
INTRODUCTION This study investigated how patients expected and experienced to be put first and cared for in diagnostic imaging settings and how putting the patient first was operationalized in practice. METHODS A qualitative field study was conducted in two Danish hospitals to investigate patients' expectations and experiences of care and involvement during CT examinations. Data collection methods included semi-structured interviews and participant observations of five examination cases. Three Computed Tomography (CT) guided lung biopsy intervention studies and two conventional CT studies of the chest of patients being investigated for lung cancer in Fast Track Cancer Referral Programs (FTCRP) were included. RESULTS Patients reported low expectations of receiving care and being involved during examinations. Perceptions of receiving care predominantly consisted of being received in a kind, personalized manner. Expectations of involvement in the procedure were reported in terms of readiness to do as they were told, complying with requests put to each patient. Concepts of care and involvement were challenged in their formal meanings and found to be entangled in complex interactions within sociotechnical boundaries. CONCLUSION Patient's expectations of receiving care and being involved in the diagnostic imaging procedures, were expressed in noncommittal terms, and were overshadowed by patients' focus on getting through the examination, in order to get an answer to their tentative diagnose. The concepts of care and patient involvement were negotiated and reconceptualized within the sociotechnical framework of the diagnostic imaging situation of the individual patient. The concept of "tinkering" is suggested as a means of understanding how patientcare is performed during diagnostic imaging procedures. IMPLICATIONS FOR PRACTICE Issues were identified that may help professionals to put "the patient first", thus, improving patient centered care.

Abstract
OBJECTIVE Medium chain fatty acids (MCFAs), which are fatty acids with chain lengths of 8 to 12 carbon atoms, have been shown to reduce food intake in rodents and humans, but the underlying mechanisms are unknown. Unlike most other fatty acids, MCFAs are absorbed from the intestine into the portal vein and enter first the liver. We thus hypothesized that MCFAs trigger the release of hepatic factors that reduce appetite. METHODS The liver transcriptome in mice that were orally administered MCFAs as C8:0 triacylglycerol (TG) was analyzed. Circulating growth/differentiation factor 15 (GDF15), tissue Gdf15 mRNA and food intake were investigated after acute oral gavage of MCFAs as C8:0 or C10:0 TG in mice. Effects of acute and subchronic administration of MCFAs as C8:0 TG on food intake and body weight were determined in mice lacking either the receptor for GDF15, GDNF Family Receptor Alpha Like (GFRAL), or GDF15. RESULTS Hepatic and small intestinal expression of Gdf15 and circulating GDF15 increased after MCFAs ingestion, while intake of typical dietary long-chain fatty acids (LCFAs) had no effect. Plasma GDF15 levels also increased in the portal vein with MCFA intake, indicating that in addition to the liver, the small intestine contributes to the rise in circulating GDF15. Acute oral provision of MCFAs decreased food intake over 24 hours compared with a LCFA-containing bolus, and this anorectic effect required the GDF15 receptor, GFRAL. Moreover, subchronic oral administration of MCFAs reduced body weight over 7 days, an effect that was blunted in mice lacking either GDF15 or GFRAL. CONCLUSIONS We have identified ingestion of MCFAs as a novel nutritional approach that increases circulating GDF15 in mice and have revealed that the GDF15-GFRAL axis is required for the full anorectic effect of MCFAs.

Abstract
Exercise profoundly influences glycemic control by enhancing muscle insulin sensitivity, thus promoting glucometabolic health. While prior glycogen breakdown so far has been deemed integral for muscle insulin sensitivity to be potentiated by exercise, the mechanisms underlying this phenomenon remain enigmatic. We have combined original data from 13 of our studies that investigated insulin action in skeletal muscle either under rested conditions or following a bout of one-legged knee extensor exercise in healthy young male individuals (n = 106). Insulin-stimulated glucose uptake was potentiated and occurred substantially faster in the prior contracted muscles. In this otherwise homogenous group of individuals, a remarkable biological diversity in the glucometabolic responses to insulin is apparent both in skeletal muscle and at the whole-body level. In contrast to the prevailing concept, our analyses reveal that insulin-stimulated muscle glucose uptake and the potentiation thereof by exercise are not associated with muscle glycogen synthase activity, muscle glycogen content, or degree of glycogen utilization during the preceding exercise bout. Our data further suggest that the phenomenon of improved insulin sensitivity in prior contracted muscle is not regulated in a homeostatic feedback manner from glycogen. Instead, we put forward the idea that this phenomenon is regulated by cellular allostatic mechanisms that elevate the muscle glycogen storage set point and enhance insulin sensitivity to promote the uptake of glucose toward faster glycogen resynthesis without development of glucose overload/toxicity or feedback inhibition.

Abstract
INTRODUCTION Liver-expressed antimicrobial peptide-2 (LEAP2) is an endogenous ghrelin receptor antagonist, which is upregulated in the fed state and downregulated during fasting. We hypothesized that the ketone body beta-hydroxybutyrate (BHB) is involved in the downregulation of LEAP2 during conditions with high circulating levels of BHB. METHODS Hepatic and intestinal Leap2 expression were determined in 3 groups of mice with increasing circulating levels of BHB: prolonged fasting, prolonged ketogenic diet, and oral BHB treatment. LEAP2 levels were measured in lean and obese individuals, in human individuals following endurance exercise, and in mice after BHB treatment. Lastly, we investigated Leap2 expression in isolated murine hepatocytes challenged with BHB. RESULTS We confirmed increased circulating LEAP2 levels in individuals with obesity compared to lean individuals. The recovery period after endurance exercise was associated with increased plasma levels of BHB levels and decreased LEAP2 levels in humans. Leap2 expression was selectively decreased in the liver after fasting and after exposure to a ketogenic diet for 3 weeks. Importantly, we found that oral administration of BHB increased circulating levels of BHB in mice and decreased Leap2 expression levels and circulating LEAP2 plasma levels, as did Leap2 expression after direct exposure to BHB in isolated murine hepatocytes. CONCLUSION From our data, we suggest that LEAP2 is downregulated during different states of energy deprivation in both humans and rodents. Furthermore, we here provide evidence that the ketone body, BHB, which is highly upregulated during fasting metabolism, directly downregulates LEAP2 levels. This may be relevant in ghrelin receptor-induced hunger signaling during energy deprivation.

Abstract
The gastric hormone ghrelin stimulates food intake and increases plasma glucose through activation of the growth hormone secretagogue receptor (GHSR). Liver-expressed antimicrobial peptide 2 (LEAP2) has been proposed to inhibit actions of ghrelin through inverse effects on GHSR activity. Here, we investigate the effects of exogenous LEAP2 on postprandial glucose metabolism and ad libitum food intake in a randomized, double-blind, placebo-controlled, crossover trial of 20 healthy men. We report that LEAP2 infusion lowers postprandial plasma glucose and growth hormone concentrations and decreases food intake during an ad libitum meal test. In wild-type mice, plasma glucose and food intake are reduced by LEAP2 dosing, but not in GHSR-null mice, pointing to GHSR as a potential mediator of LEAP2’s glucoregulatory and appetite-suppressing effects in mice. Exogenous LEAP2 lowers postprandial plasma glucose excursions Exogenous LEAP2 suppresses ad libitum food intake During fasting, exogenous LEAP2 increases insulin secretion and suppresses lipolysis The GHSR is required for eliciting LEAP2 effects in mice

Abstract
CONTEXT The mechanisms underlying Roux-en-Y gastric bypass (RYGB) surgery-induced weight loss and the immediate postoperative beneficial metabolic effects associated with the operation remain uncertain. Enteroendocrine cell (EEC) secretory function has been proposed as a key factor in the marked metabolic benefits from RYGB surgery. OBJECTIVE To identify novel gut-derived peptides with therapeutic potential in obesity and/or diabetes by profiling EEC-specific molecular changes in obese patients following RYGB-induced weight loss. SUBJECTS AND METHODS Genome-wide expression analysis was performed in isolated human small intestinal EECs obtained from 20 gut-biopsied obese subjects before and after RYGB. Targets of interest were profiled for preclinical and clinical metabolic effects. RESULTS Roux-en-Y gastric bypass consistently increased expression levels of the inverse ghrelin receptor agonist, liver-expressed antimicrobial peptide 2 (LEAP2). A secreted endogenous LEAP2 fragment (LEAP238-47) demonstrated robust insulinotropic properties, stimulating insulin release in human pancreatic islets comparable to the gut hormone glucagon-like peptide-1. LEAP238-47 showed reciprocal effects on growth hormone secretagogue receptor (GHSR) activity, suggesting that the insulinotropic action of the peptide may be directly linked to attenuation of tonic GHSR activity. The fragment was infused in healthy human individuals (n = 10), but no glucoregulatory effect was observed in the chosen dose as compared to placebo. CONCLUSIONS Small intestinal LEAP2 expression was upregulated after RYGB. The corresponding circulating LEAP238-47 fragment demonstrated strong insulinotropic action in vitro but failed to elicit glucoregulatory effects in healthy human subjects.

Abstract
Abstract
Background
Patients with a native or re CoA with an invasively meassured peak to peak gardient >20 mmHg have a guideline indication for intervention. The decision regarding transcatheter versus surgical intervention depends on a variety of factors including location and complexity of CoA, patient/parent preference and availability of a team capable to perform the intevention with a low rate of complications. The aim of the present analysis was to describe factors associated with risk for procedural complications during transcatheter interventions in CoA. Separate anlysis was done for complications at intervention site and at access site.
Methods
All consecutive patients undergoing catheter interventions for CoA from 1st of January 2000 to 31st of December 2016 were identified by each of the particpating nine centers. The nine centers perform all catheter interventions for CoA for a complete population coverage of 25 millions inhabitants. A common protocol was filled out from medical records. Exclusion criteria were weight less than 20 kg at the time of intervention or Norwood surgery for hypoplastic left heart surgery. Complications at the intervention site included aneurysm formation, dissection of the aorta, extravasation of the aorta or neurological impairment. Complications at the access site was defined as any complication that prolonged the hospital stay.
Results
590 interventions were performed on 520 patients: two interventions n=76, three: n=11, four n=2 and one patient underwent five interventions. There was no mortality in relation to the procedure or during the hospitalisation. The age span of the patients was wide; 4–79 years old (median= 23). 51% had a native CoA, 42% post surgery re-CoA, 22% had had a previous catheter intervention. In 160 (27%) of the interventions balloon dilatation only was performed. Overall, procedural succes was 87%, n=513, 44 procedures (8%) were partially successful and 9 procedures (2%) were not successful. 512 (87%) had one day in hospital stay and 17 patients (6%) had a hospital stay longer than 3 days. In 11 procedures (1.9%) at least one complication occurred at the intervention site; (6 aneurysm formation, 3 neurological impairment, 3 dissection of aorta, 2 extra vasation of aorta), nine of them without prolonged hospital stay. In 25 procedures (4.2%) at least one complications at the access site was observed. Access site complications were associated with older age (mean 38 years (10–79))
Conclusions
In a large, multicenter registry with complete follow-up, complications at the intervention site occurred in 1.9% and at the access site in 4.2% of interventions. Transcatheter intervention of CoA can be performed with low risk of complications.

Abstract
Abstract
A review of pandemic plans and international approaches to pandemics focusing on the responsibilities of medical students should they be called to help in times of need. Are there specific guidelines or competencies in place with respect to medical students? Are medical students being utilised to their maximal capability when compared across different nations on an international basis? These questions were kept in mind during the evaluation and analysis of publicly available pandemic plans and other international systems concerning the approach to pandemics. The main differences, strengths and weaknesses of these responses will be highlighted. The presentation will conclude with proposals of the specific role medical students could play in the pandemic response and the importance of their contribution on an international level.

Abstract
Abstract
Background
The ASPHER V4 Working Group (WG) was established in 2016 and officially launched during the 9th European Public Health Conference in Vienna. One of the key objectives of the WG is to strengthen public health capacity development in V4 countries. The WG supports the implementation of the recently reviewed European Action Plan for Strengthening Public Health Capacities (EAP). The EAP’s review highlighted the need to focus further action on four enabling Essential Public Health Functions (EPHOs) including human resources for public health. This is why the WG is heavily involved in the recent development of a new Road map for professionalising the public health workforce, one of the products of the recently established Coalition of Partners (CoP) that was convened by the WHO Regional Office for Europe in close cooperation with ASPHER and Maastricht University.
Objectives
Supporting the WHO CoP with a focus on development and further implementation of a new Road map for professionalising public health workforce in V4 countries. Using a new rapid assessment tool to evaluate the state of the public health profession in the Czech Republic. Sharing the report on the current state of public health professions in the Czech Republic with the WG and using it as a comparison of the current state in all V4 countries.
Results
Key strengths and weaknesses of the first rapid assessment of the current state of the public health profession in the Czech Republic are presented. Key actions are proposed for the WG: a) Preparation of a grant proposal to the International V4 Fund and b) Continuing active involvement in CoP activities.
Conclusions
The rapid assessment tool for evaluating the state of the public health profession was successfully implemented in the Czech Republic with the close cooperation of academia, researchers, policy makers and practitioners. The summary confirms that further work on the professionalization of the public health workforce is needed.
Key messages
ASPHER V4 WG is strongly involved in the development of a new road map for professionalising the public health workforce, coordinated by the WHO CoP, ASPHER and Maastricht University. Summary of the first rapid assessment of the current state of the public health profession in the Czech Republic confirms the importance of further action in this area of work.

Abstract
A rising wave of technologies and instruments are enabling more labs and clinics to make a variety of measurements related to tissue viscoelastic properties. These instruments include elastography imaging scanners, rheological shear viscometers, and a variety of calibrated stress-strain analyzers. From these many sources of disparate data, a common step in analyzing results is to fit the measurements of tissue response to some viscoelastic model. In the best scenario, this places the measurements within a theoretical framework and enables meaningful comparisons of the parameters against other types of tissues. However, there is a large set of established rheological models, even within the class of linear, causal, viscoelastic solid models, so which of these should be chosen? Is it simply a matter of best fit to a minimum mean squared error of the model to several data points? We argue that the long history of biomechanics, including the concept of the extended relaxation spectrum, along with data collected from viscoelastic soft tissues over an extended range of times and frequencies, and the theoretical framework of multiple relaxation models which model the multi-scale nature of physical tissues, all lead to the conclusion that fractional derivative models represent the most succinct and meaningful models of soft tissue viscoelastic behavior. These arguments are presented with the goal of clarifying some distinctions between, and consequences of, some of the most commonly used models, and with the longer term goal of reaching a consensus among different sub-fields in acoustics, biomechanics, and elastography that have common interests in comparing tissue measurements.

Abstract
SummaryMeasuring intradiscal pressure is one way of mechanically assessing the discs degenerative state. In this study, the load-bearing capacity of degenerated and their adjacent lumbar intervertebral discs was evaluated using two different injury models. Seventeen adolescent pigs were divided into two groups, an annulus injury group and an endplate injury group. The annulus injury group was subjected to a stab incision in the L3-L4 disc, whereas the endplate injury group received a cranial endplate perforation of the L4 vertebral body. Both groups were biomechanically evaluated three months later using a miniaturized servohydraulic testing machine across L2-L4 and with two pressure needles inserted into the nucleus pulposus of the L2-L3 and L3-L4 discs. Linear relationships between the intradiscal pressure and the applied load were determined within the load range studied. When comparing the ratio of the injured to the adjacent disc pressure, the endplate injury was lower (mean value 0.31) than the annulus injury (mean value 0.51). The pressures in the discs adjacent to the degenerated level were found to be slightly higher. This increase can be expected due to a redistribution in mobility demands in segments adjacent to those with increased stiffness, i.e. degenerated intervertebral discs.

Abstract
SummaryDegenerative and reactive structural alterations occurring after experimentally-induced disc degeneration were evaluated using a porcine model. A cranial perforation was made through the L4 vertebral endplate into the nucleus pulposus. Three months later, the lumbar intervertebral disc and adjacent vertebrae were dissected, fixed in formalin and further processed for histopathological analyses. The results showed that there were nucleus pulposus fragments, rather than a distinct border between the nucleus and annulus fibrosus. The central lamellae were distorted and delamination of the outer anterior layers was observed. Blood vessels emerged from the adjacent tissue, penetrated the annulus and branched into the residues of the nucleus. Nerve fibres accompanying the blood vessels could be recognized in the disc within the connective scar tissue. The epiphyseal cartilage plates in the vertebrae were hypertrophic in several areas and there was bone formation directed towards the centre of the vertebral body and the disc. Hypertrophic hyaline cartilage, newly formed bone and scar tissue filled the injury canal. A slight chronic inflammatory reaction was evident along vascular buds. The reactive changes dominated over the degenerated features in the operated disc. Physiological loading enhanced the infiltration of various tissue types characterizing immature cartilage formation. Prominent neovascularisation of the central parts of the disc is likely to be of key importance in turning the degenerative features of the remaining tissue into reactive healthy structures.

Abstract
Both physiologically and ecologically based explanations have been proposed to account for among-species differences in lifespan, but they remain poorly tested. Phylogenetically explicit comparative analyses are still scarce and those that exist are biased towards homoeothermic vertebrates. Insect studies can significantly contribute as lifespan can feasibly be measured in a high number of species, and the selective forces that have shaped it may differ largely between species and from those acting on larger animals. We recorded adult lifespan in 98 species of geometrid moths. Phylogenetic comparative analyses were applied to study variation in species-specific values of lifespan and to reveal its ecological and life-history correlates. Among-species and between-gender differences in lifespan were found to be notably limited; there was also no evidence of phylogenetic signal in this trait. Larger moth species were found to live longer, with this result supporting a physiological rather than ecological explanation of this relationship. Species-specific lifespan values could not be explained by traits such as reproductive season and larval diet breadth, strengthening the evidence for the dominance of physiological determinants of longevity over ecological ones.

Abstract
Development of safe and efficient radiotherapy routines requires quantification of the delivered absorbed dose to the cancer tissue in individual patients. In vivo dosimetry can provide accurate information about the absorbed dose delivered during treatment. In the current study, a novel silver-nanosensor formulation based on poly(vinylpyrrolidinone)-coated silver nanoparticles formulated in a gelation matrix composed of sucrose acetate isobutyrate has been developed for use as an in vivo dosimeter for external beam radiotherapy. In situ photonuclear reactions trigger the formation of radioactive (106)Ag, which enables post treatment verification of the delivered dose using positron emission tomography imaging. The silver-nanosensor was investigated in a tissue equivalent thorax phantom using clinical settings and workflow for both standard fractionated radiotherapy (2 Gy) and stereotactic radiotherapy (10- and 22 Gy) in a high-energy beam setting (18 MV). The developed silver-nanosensor provided high radiopacity on the planning CT-scans sufficient for patient positioning in image-guided radiotherapy and provided dosimetric information about the absorbed dose with a 10% and 8% standard deviation for the stereotactic regimens, 10 and 22 Gy, respectively.

Abstract
OBJECTIVES To study the efficacy of tailored behavioural medicine treatment within a physical therapy framework. METHODS The study was a randomized controlled study (RCT): tailored behavioural medicine treatment (EXT) delivered by physical therapists (PTs) was compared with exercise-based treatment (CT). Thirty-two adolescents (mean age 14.3 years) with persistent pain participated. Data on pain-related disability and school attendance (primary outcomes), pain intensity, catastrophizing, fear of movement and self-efficacy were collected. RESULTS The pain-related disability measured by the Functional Disability Inventory (FDI) resulted in mean score change of EXT = -18 and CT = -11, respectively. A significant change within both groups was found (EXT p = 0.003, CT p = 0.001), and a large effect size for FDI between the conditions was demonstrated (AUC of 0.77). For school attendance post-treatment, no difference was found between conditions. For secondary outcomes, a significant improvement in pain intensity and pain catastrophizing was found for the EXT and self-efficacy for the CT groups but no statistically significant difference between the two conditions was detected. Caution should be given to the small sample size, as it may affect the interpretation and generalizability of the results. CONCLUSION In this study, differences between tailored behavioural medicine treatment delivered by PTs and exercise-based treatment could not be demonstrated, although the effect size was large. Patients who received either treatment demonstrated significant changes over time in pain-related disability. The low number of participants and suboptimal tailoring of the psychological components may partly explain the failure to demonstrate differences between groups, and future studies are warranted.

Abstract
Physical exercise increases peripheral insulin sensitivity, but regional differences are poorly elucidated in humans. We investigated the effect of aerobic exercise training on insulin-stimulated glucose uptake in five individual femoral muscle groups and four different adipose tissue regions, using dynamic (femoral region) and static (abdominal region) 2-deoxy-2-[¹⁸F]fluoro-d-glucose (FDG) PET/CT methodology during steady-state insulin infusion (40 mU·m⁻²·min⁻¹). Body composition was measured by dual X-ray absorptiometry and MRI. Sixty-one healthy, sedentary [V(O2max) 36(5) ml·kg⁻¹·min⁻¹; mean(SD)], moderately overweight [BMI 28.1(1.8) kg/m²], young [age: 30(6) yr] men were randomized to sedentary living (CON; n = 17 completers) or moderate (MOD; 300 kcal/day, n = 18) or high (HIGH; 600 kcal/day, n = 18) dose physical exercise for 11 wk. At baseline, insulin-stimulated glucose uptake was highest in femoral skeletal muscle followed by intraperitoneal visceral adipose tissue (VAT), retroperitoneal VAT, abdominal (anterior + posterior) subcutaneous adipose tissue (SAT), and femoral SAT (P < 0.0001 between tissues). Metabolic rate of glucose increased similarly (~30%) in the two exercise groups in femoral skeletal muscle (MOD 24[9, 39] μmol·kg⁻¹·min⁻¹, P = 0.004; HIGH 22[9, 35] μmol·kg⁻¹·min⁻¹, P = 0.003) (mean[95% CI]) and in five individual femoral muscle groups but not in femoral SAT. Standardized uptake value of FDG decreased ~24% in anterior abdominal SAT and ~20% in posterior abdominal SAT compared with CON but not in either intra- or retroperitoneal VAT. Total adipose tissue mass decreased in both exercise groups, and the decrease was distributed equally among subcutaneous and intra-abdominal depots. In conclusion, aerobic exercise training increases insulin-stimulated glucose uptake in skeletal muscle but not in adipose tissue, which demonstrates some interregional differences.

Abstract
Purpose: A minipig model was used to demonstrate MRI findings in the first three months after an annular disruption. Methods: An incision was made into one of the lumbar discs in each of eight minipigs in the outer and middle parts of the annulus. The remaining intact discs in the lumbar and thoracolumbar regions were used as controls. MR imaging was performed one month and three months after trauma using both a 1.0 T and a 1.5 T MR unit. The histologic analysis was also carried out to demonstrate morphological changes in disc. Results: Eighty-eight percent of the injured discs had a diminished area of bright signal in the nucleus pulposus, also in cases where no signs of trauma in the annulus could be detected in MRI. The degeneration process of the nucleus pulposus was shown to progress during follow-up. High intensity zones were detected in 50% of the injured discs and they tended to appear already after one month follow-up. Histological examination showed that the high-intensity zone contained clusters of nuclear cells originating in the nucleus pulposus. Conclusion: It is concluded that lesions producing high-intensity zones can be induced in an experimental animal model and it can already be detected one month after the trauma. Degeneration process of the nucleus is generally initiated after a peripheral annular lesion.

Abstract
AIMS Maternal diabetes may affect offspring cognitive function. The objective of the study was to evaluate cognitive function and potential predictors hereof in adult offspring of women with Type 1 diabetes. METHODS We conducted a follow-up study of adult offspring of women with Type 1 diabetes (n = 158) and a reference group from the background population (n = 118). The main outcome measure was offspring cognitive function measured by global cognitive score, derived from Raven's Progressive Matrices and three verbal subtests from the Weschler Adult Intelligence Scale. RESULTS Offspring of women with Type 1 diabetes obtained lower global cognitive scores (94.8 vs. 100.0, P = 0.004) than offspring from the background population. When adjusted for confounders, the groups no longer differed significantly (difference 0.4, 95% CI -3.3 to 4.). Positive predictors of cognitive function in offspring of women with diabetes were family social class, parental educational level, maternal diabetes duration, male gender and offspring age, whereas parity ≥ 1 and gestational age < 34 weeks were negative predictors. We found no association with maternal glycaemia during pregnancy or with neonatal hypoglycaemia. CONCLUSIONS Impaired cognitive function in adult offspring of women with Type 1 diabetes compared with the background population apparently reflects differences with respect to well-known confounders. However, harmful effects of maternal hyperglycaemia may be mediated through delivery at < 34 weeks.
