Abstract
Abstract
Background
The timing of eating, chrono-nutrition, is a relatively new research area, where the focus is not on only what we eat but also when we eat and of irregularity between days. Chrono-nutrition have been associated with cardiovascular risk factors among adults. Societal factors influence the chrono-nutrition, but there is limited research on how different socioeconomic factors are associated with chrono-nutrition, especially among children. The aim of this study is to examine the association between parental socioeconomic status and irregularity of children’s energy intake.
Methods
We used data from the DAGIS (Increased Health and Wellbeing in Preschools) study in years 2015-2016, in which 864 preschool children participated (age 3-6 years old). Childreńs dietary intake was measured by a 3-day food record. We included only children that had complete data from all three days and the child was at day care on two of those days and one day was a weekend day (n = 568). To calculate the irregularity score, the absolute difference between the daily energy intake and 3-day mean intake for each three days was divided by the 3-day mean energy intake, multiplied by 100 and then averaged over the 3 days; this served as a measure of irregularity of energy intake, with a low score indicating a more regular energy intake and a higher more irregular energy intake. The parents reported highest parental educational level and household income on a questionnaire. The associations were tested by general linear models on SPSS.
Results
No association was found between parental educational level or household income with irregularity of children’s energy intake.
Conclusions
There was no association between parental socioeconomic status and children’s irregularity of energy intake. Other aspects of children’s chrono-nutrition should also be tested to be able to conclude that children’s chrono-nutrition is not influenced by parental socioeconomic status.
Key messages
• We found no association between parental socioeconomic status and irregularity in children’s energy intake.
• Chrono-nutrition among children is under-examined.

Abstract
Background It is well-known that frequent nature visits are associated with health benefits in children. Global climate crisis and environmental challenges emphasize the need for reconnecting children to nature, as well. Young children’s nature connectedness (NC) involves enjoyment of nature, sense of responsibility, empathy, and awareness of nature. The study examines whether there is an association between the frequency of parent-child nature visits and young children’s NC. Methods The study uses WEB survey data from the Finnish Empowered by Nature project. Respondents, n = 1463, were parents of children aged 2 to 7 years old. NC was assessed by 11-items derived from the NC questionnaire of Sobko et al (2018). Multinomial logistic regression analysis was used and the lowest tertile of NC was used as reference group. Analysis were adjusted for child’s age and gender, and highest education of parent. Results Children with moderate (1-2 times a week in previous month) or high (3 times a week or more) frequency of parent-child nature visits were more likely to have strong than weak NC compared to children with low frequency (less than once a week) of adult-child nature visits. Odds ratios (OR) in adjusted models were: moderate frequency 1.67 (1.21- 2.32), and high frequency 2.31 (1.67-3.18). The odds of having medium NC compared to weak NC were more likely in moderate frequency compared to low frequency of parent-child nature visits in the adjusted model (OR 1.46; 1.07-2.00). Conclusions The results highlight the importance of parents visiting nature frequently with their children during early childhood. It promotes young children’s NC and may further contribute to raising environmentally responsible children. Key messages • More frequent parent-child visits promote young children’s nature connectedness which involves enjoyment of nature, sense of responsibility, empathy, and awareness of nature. • A strong nature connectedness among children is highly relevant, as it may contribute to raise environmentally responsible children.

Abstract
Abstract
Background and objectives
The effectiveness of a health behavior intervention can depend on the extent to which the intervention is implemented; higher degree of implementation (DOI) might associate with larger intervention effects. This study examined whether the parental DOI of an health behavior intervention had an effect on children's consumption of sugar-sweetened beverages (SSB) and was the effect mediated by home factors.
Methods
the DAGIS preschool intervention was conducted in 2017-2018 in Finland among 3-6-year-olds with valid data from 476 children. At baseline and follow-up parents reported 1) children's SSB consumption in a semi-quantified food frequency questionnaire, 2) availability of SSB at home, parental role modelling of drinking SSB, and norm (parental view on the suitable amount of SSB for children), and 3) DOI: a dichotomized sum variable on several aspects of parental program implementation. In the analyses, high and low DOI were compared to control group. Mediation analysis of the effect of DOI on the change in children's SSB consumption via change in availability, role modelling and norm was conducted with R statistical software.
Results
High DOI was associated with reduced consumption of SSB (B -27.71, 95% CI -49.05, -4.80). No mediated effects were found. All studied mediators impacted the change in SSB consumption, but the DOI had no effect on the change in mediators.
Conclusions
Intervention effect on the consumption of SSB was only found in the high DOI group, which supports the importance of assessing intervention implementation. Since the found effect was not mediated by the studied mediators, other possible mediators should be examined, as understanding intervention mediators is crucial in developing successful interventions.

Abstract
Abstract
Background and objectives
Child's temperament dimensions have been linked with different weight outcomes as well as dietary factors such as consumption of fruit and vegetables, sugar-rich foods and drinks and an overall dietary quality. Links between temperament dimensions and energy intake, however, remain under-examined. This study expands the literature by investigating associations between child's temperament dimensions and energy intake.
Methods
Altogether 505 Finnish children aged 3-6 years provided data for the analyses. The data is a part of the DAGIS (Increased Health and Wellbeing in Preschools) study conducted in 2015-2016. Child's energy intake was measured with 3-day food records. To be included, children had to 1) have food record for two preschool days and one weekend day and 2) to have consumed both lunch and an afternoon snack in the preschool on the two preschool days. The very short form of Children's Behavior Questionnaire was used to measure child's temperament dimensions. Concurrent associations between three temperament dimensions (surgency, negative affectivity, and effortful control) and energy intake were examined using linear regression models adjusted for child's age, sex, mother's highest education, and moderate-to-vigorous physical activity.
Results
Surgency, temperament dimension referring to characteristics such as impulsivity, high activity level and high approach, was positively associated with energy intake. Effortful control or negative affectivity were not associated with energy intake.
Conclusions
The findings imply that temperamental surgency may be one relevant determinant of energy intake among preschool children. The result is in line with previous studies linking child's surgency as well as its specific facets, such as impulsivity, with weight outcomes and food approach behaviors. Considering child's individual temperament dimensions when counselling families in eating issues could be beneficial.
Key messages
• Surgency, a temperament dimension referring to characteristics such as impulsivity, high activity level and high approach, was positively associated with energy intake.
• When promoting children’s balanced eating, tailored support for parents acknowledging child’s temperament could be beneficial.

Abstract
We describe a computational light-sheet microscope designed for hyperspectral acquisition at high spectral resolution. The fluorescence light emitted from the full field-of-view is focused along the entrance slit of an imaging spectrometer using a cylindrical lens. To acquire the spatial dimension orthogonal to the slit of the spectrometer, we propose to illuminate the specimen with a sequence of structured light patterns and to solve the image reconstruction problem. Beam shaping is obtained simply using a digital micromirror device in conjunction with a traditional selective plane illumination microscopy setup. We demonstrate the feasibility of this method and report the first results in vivo in hydra specimens labeled using two fluorophores.

Abstract
Characterization and quantification of individual whey proteins are of crucial importance to many industrial dairy processes. Labor intensive wet-chemical methods are still being used for this purpose, but a rapid quantification method for individual whey proteins is highly desired. This work investigate the utility of Fourier transform mid-infrared spectroscopy and Fourier transform near-infrared spectroscopy for rapid quantification of the two main whey proteins (β-lactoglobulin and α-lactalbumin) in complex aqueous whey solutions simulating production process streams. MIR and NIR spectra obtained on whey samples with known and varying amounts of the proteins of interest and are used to develop partial least squares prediction models. Selection of informative wavelength regions allowed for prediction of β-lactoglobulin and α-lactalbumin concentrations with very high precision and accuracy (root mean square error of cross-validation, or RMSECV, of 0.6% and R2 of 0.99 for NIR), demonstrating the potential of being implemented for rapid in-line monitoring of protein composition in industrial whey streams. Two-dimensional MIR-NIR correlation spectroscopy is used to identify the most informative parts of the NIR spectra in relation to protein secondary structure. In addition multivariate curve resolution is applied to the MIR data to resolve mixture spectra and to elucidate the spectral ranges that were most useful in distinguishing between the two whey proteins. The study concludes that NIR spectroscopy has potential for accurate in-line protein quantification and overall secondary protein structure quantification which open new possibilities for in-line industrial applications.

Abstract
The impact of the intestinal and fecal microbiome on animal health has received considerable attention in recent years and has direct implications for the veterinary and wildlife rehabilitation fields. To examine the effects of rehabilitation on the microbiome in Kemp’s ridley sea turtlesLepidochelys kempii, fecal samples from 30 incidentally captured juveniles were collected during rehabilitation. Samples were analyzed to determine alpha- (α) and beta- (β) diversity as well as the taxonomic abundance of the fecal microbiota during rehabilitation and in response to treatment with antibiotics. The fecal microbial communities of animals housed in rehabilitation for a ‘short-term’ stay (samples collected 0-9 d post-capture) were compared with ‘long-term’ (samples collected 10+ d post-capture) and ‘treated’ groups (samples collected from turtles that had received antibiotic medication). Results of this study indicate that the most dominant phylum in fecal samples wasBacteroidetes(relative abundance, 45.44 ± 5.92% [SD]), followed byFirmicutes(26.62 ± 1.58%),Fusobacteria(19.49 ± 9.07%), andProteobacteria(7.39 ± 1.84%). Similarly, at the family level,Fusobacteriaceae(28.36 ± 17.75%),Tannerellaceae(15.41 ± 10.50%),Bacteroidaceae(14.58 ± 8.48%), andRuminococcaceae(11.49 ± 3.47%) were the most abundant. Our results indicated that both antibiotic-treated and long-term rehabilitated turtles demonstrated a significant decrease in β-diversity when compared to short-term rehabilitated turtles. Our results likewise showed that the length of time turtles spent in rehabilitation was negatively correlated with α- and β-diversity. This study demonstrates the importance of a judicious use of antibiotics during the rehabilitation process and emphasizes the importance of limiting the length of hospital stays for sick and injured sea turtles as much as possible.

Abstract
Abstract
A collaborative study was conducted for determination of glucosamine in raw materials and dietary supplements containing glucosamine sulfate and/or glucosamine hydrochloride by high-performance liquid chromatography (HPLC) with N-(9-fluorenyl-methoxycarbonyloxy) succinimide (FMOC-Su) derivatization. Thirteen blind materials, one pair of which were duplicates, were tested by 12 collaborating laboratories. The test samples consisted of various commercial products, including tablets, capsules, drink mix, and liquids as well as raw materials, blanks, and those for spike recovery analyses. The tests with blank products and products spiked with glucosamine showed good specificity of the method. The average recoveries at spike levels of 100 and 150% of the declared amount were 99.0% with a relative standard deviation (RSD) of 2.1%, and 101% with an RSD of 2.3%, respectively. The test results between laboratories on each commercial product were reproducible with RSD values of no more than 4.0%, and the results were repeatable in the same laboratory with an average RSD of 0.7%. HorRat values ranged from 0.5 to 1.7 on both tests of spike recovery and reproducibility between laboratories on commercial products. The average determination coefficient of the calibration curves from the laboratories was 0.9995 with an RSD of 0.03%. All of the 12 collaborating laboratories succeeded in the study and none of their reported test results were outliers, partly indicating the robustness of the method. It is recommended that the method be accepted by AOAC INTERNATIONAL as Official First Action.

Abstract
UNLABELLED An electronic health record (eHR) review of Veterans with a spinal cord injury and disorder (SCI/D) was conducted to understand the extent to which Veterans Affairs (VA) providers pursue workups for secondary causes of osteoporosis in this population. Laboratory tests for secondary causes were ordered in only one-third of Veterans, with secondary causes identified in two-thirds of those tested, most frequently, hypogonadism and hypovitaminosis D. PURPOSE To identify workups for secondary causes of osteoporosis in SCI/D and the extent to which subspecialty consultations are sought. METHODS A total of 3018 prescriptions for an osteoporosis medication (bisphosphonate, calcitonin, denosumab, raloxifene, teriparatide) among 2675 Veterans were identified in fiscal years 2005-2015 from VA administrative databases. Approximately 10% of these prescriptions were selected for eHR review. RESULTS eHR records of 187 Veterans with a SCI/D who had received pharmacological treatment for osteoporosis were reviewed. Workups for secondary causes of osteoporosis were performed in 31.5% of Veterans (n = 59) with approximately 64.4% of those tested (n = 38) having at least one abnormality. Hypogonadism (52.0% of those tested) and hypovitaminosis D (50.0% of those tested) were the most common secondary causes of osteoporosis identified in this population. Approximately 10% of primary care and SCI providers consulted subspecialists for further evaluation and treatment of osteoporosis. Endocrinologists more frequently performed a workup for secondary causes of osteoporosis compared to other provider specialties. CONCLUSIONS Screening for secondary causes of osteoporosis, particularly for hypogonadism and hypovitaminosis D, should be considered in patients with a SCI/D.

Abstract
Abstract
Background
Childcare is an important setting for young children’s food consumption as, in Finland, most children eat three meals a day in childcare. Thus, it is important to recognize determinants of children’s dietary intake in childcare. The aim of this study was to examine food-related factors at preschool and manager-level and their association with children’s fruit, vegetable and fibre intake at preschool.
Methods
The study was a part of the cross-sectional DAGIS survey conducted in 2015-2016. It aimed to examine 3-6-year-old preschoolers’ energy balance-related behaviors in Finland. Preschool managers from 58 preschools filled in a questionnaire on food and nutrition related factors at preschool such as kitchen type, food policies, food education, the manager’s possibilities to impact fruit and vegetable supply and cooperation challenges with the catering service. Preschool personnel kept food record for the children (n = 585) on two preschool days. Multilevel linear and logistic regression analyses were conducted with age, gender and municipality as confounders, preschool-level factors as independent variables and children’s vegetable (g/day) and fruit (yes vs. no) consumption, and fibre intake (g/MJ) as outcome variables.
Results
Having many written food policies in the preschool was associated with higher intake of vegetables (p = 0.01) and fibre (p = 0.03) among the children. Having at least 2 out of 3 different cooperation challenges with the catering service was associated with higher intake of fibre (0.03) and lower odds of eating fruits (p = 0.01).
Conclusions
Written food policies and manager-reported challenges with the catering service were associated with children’s vegetable, fruit and fiber intake at preschool. Factors that are relatively distal from the meal situations may impact children’s food intake at preschool and should be taken into account when promoting healthy food intake at preschool, but more studies are needed.
Key messages
Written food policies and good cooperation between the preschool and catering services may be of benefit to children’s healthy food intake at preschool. The relation between preschool and manager-level factors and children’s food intake are very little studied, and thus more studies are needed before conclusions can be made.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
Lactose reduced dairy products are more prone to Maillard reactions due to the presence of reactive monosaccharides. Conventional β-galactosidases, which are used for lactose hydrolysis in lactose-reduced dairy products, will lead to conversion of lactose into glucose and galactose, where especially galactose is very reactive during Maillard reactions. Some β-galactosidases have transgalactosylating activity and will thus convert lactose into galacto-oligosaccharides (GOS) and hereby limit the release of galactose. The aim of this study was to investigate the extent of participation of GOS in Maillard reactions in comparison to lactose, a 50:50 mixture of glucose and galactose, and galactose exclusively in sodium caseinate-based milk-like model systems heated at 130 and 75 °C at pH 6.8. The GOS system exhibited reduced loss of free amino groups; accumulated less furosine and less of the following advanced glycation end products (AGEs): Nε-carboxyethyl lysine, methylglyoxal-derived hydroimidazolone isomers, glyoxal-derived lysine dimer, and methylglyoxal-derived lysine dimer; and also developed less browning compared to monosaccharide models. However, the GOS-caseinate system accumulated more 3-deoxyglucosone and 3-deoxygalactosone, which resulted in higher concentrations of 5-(hydroxymethyl)furfural and pyrraline. The results indicated that GOS overall participate less readily in Maillard reactions than the monosaccharides investigated but were more prone to degradation to C6 α-dicarbonyls species. Finally, relationship analysis indicated that C6 α-dicarbonyls seemed to primarily increase concentrations of 5-(hydroxymethyl)furfural instead of AGEs. Our results suggest that conversion of lactose into GOS instead of monosaccharides in milk by transgalactosylating β-galactosidases could be a useful strategy for production of lactose-free milk for people with lactose intolerance.

Abstract
Ten-eleven translocation (TET) enzymes catalyse oxidation of 5-methylcytosine to 5-hydroxymethyl cytosine. This TET-mediated conversion of 5-methylcytosine to 5-hydroxymethyl cytosine is implicated in initiating the DNA demethylation process, observed post-fertilization. Three members (TET1–3) of the TET family are differentially expressed during embryo development and appear to have different roles. Previous studies in mice suggest that TET1 is a key regulator in maintaining pluripotency in embryonic stem cells by managing epigenetic marks such as DNA methylation. This would imply that TET1 should be a regulator of epigenetic marks during embryo development, although this has not been demonstrated. Previously, we have cloned porcine TET1 from blastocysts (GenBank accession number KC137683) and demonstrated that the level of TET1 (mRNA and protein) was high in blastocysts. The protein level was greater in the inner cell mass compared with the trophectoderm. In this study, we generated TET1 knockout porcine embryos using CRISPR/Cas9 system to study the role of TET1 in controlling epigenetic marks during porcine embryo development. First, 2 sgRNA, immediately downstream of the presumable translation initiation site, were designed and synthesised; location of the sgRNA were nucleotide position at 2 to 21 bp and 23 to 42 bp, respectively (KC137683). Then, sgRNA (10 ng μL−1 each) and Cas9 mRNA (20 ng μL−1) were injected into the cytoplasm of IVF zygotes, and Day 7 blastocysts were genotyped. All embryos carried mutations on both alleles of TET1 (10/10), one homozygous and 9 biallelic mutations. However, immunocytochemistry analysis of other CRISPR/Cas9 injected embryos revealed that TET1 was not removed (10/10), indicating that the sgRNA may have not introduced a premature stop codon 3′ to the presumable translation initiation site. Therefore, 2 new sgRNA were designed to generate a premature stop codon at the 5′ side of a key functional domain, the 2-oxoglutarate-Fe(II)-dependent oxygenase domain (4690 to 5160 bp); the locations of the 2 sgRNA were 4450 to 4469 bp and 4501 to 4520 bp, respectively. Similarly, all of the embryos carried mutations in TET1 (7/7), 2 homozygous and 5 biallelic mutations. In addition, TET1 proteins were not detected in 11 of 16 blastocysts, confirmed by immunocytochemistry. In this study, we successfully generated embryos lacking TET1 by introducing designed CRISPR/Cas9 system during embryogenesis. Presence of TET1 from the first injection experiment suggests that the presumable translation initiation site is not accurate. Discrepancy between genotyping and immunocytochemistry results from the second injection experiment indicates that embryos possessing TET1 protein probably have mutations in triplets, thus no premature stop codon was synthesised. Further studies will focus on identifying the role of TET1 in maintaining pluripotency and epigenetic modification during pre-implantation stage using these embryos.

Abstract
BACKGROUND Different types of non-parental childcare have been found to associate with childhood overweight in several, but not all studies. Studies on the matter are mainly North American. OBJECTIVES The objective of our study was to examine associations between childcare use and overweight in Finland. METHODS The cross-sectional and partly retrospective data consists of 1683 3- and 5-year-old children participating in the Child Health Monitoring Development project (LATE-project) conducted in 2007-2009 in Finland. Children were measured at health check-ups and information on child's age when entering childcare, the number of childcare places the child has had, current type of childcare (parental, informal, [group] family childcare, childcare centre) and the current amount of childcare (hours) were gathered. Parents' body mass indices, family educational level, family structure, maternal smoking during pregnancy and child's birth weight were treated as covariates. RESULTS Beginning childcare before age 1 (adjusted model: odds ratio [OR] 2.53, 95% confidence interval [CI] 1.41-4.52) and, for girls only, number of childcare places (adjusted model: OR 1.33, 95% CI 1.11-1.60), were associated with an increased risk of overweight. The current type of childcare or the time currently spent in childcare was not associated with overweight. CONCLUSION Beginning childcare before age 1, which is quite rare in Finland, and having attended several childcare places were associated with overweight even when adjusting for family socioeconomic status and other family background variables. The significance of these findings needs to be further studied.

Abstract
Proteolytic activity in milk may release bitter-tasting peptides and generate free amino terminals that react with carbohydrates, which initiate Maillard reaction. Ultrahigh temperature (UHT) heat treatment inactivates the majority of proteolytic enzymes in milk. In lactose-hydrolyzed milk a β-galactosidase preparation is applied to the milk after heat treatment, which has proteolytic side activities that may induce quality deterioration of long-term-stored milk. In the present study proteolysis, glycation, and volatile compound formation were investigated in conventional (100% lactose), filtered (60% lactose), and lactose-hydrolyzed (<1% lactose) UHT milk using reverse phase high-pressure liquid chromatography-mass spectrometry, proton nuclear magnetic resonance, and gas chromatography-mass spectrometry. Proteolysis was observed in all milk types. However, the degree of proteolysis was significantly higher in the lactose-hydrolyzed milk compared to the conventional and filtered milk. The proteins most prone to proteolysis were β-CN and αs1-CN, which were clearly hydrolyzed after approximately 90 days of storage in the lactose-hydrolyzed milk.

Abstract
The enzymatic hydrolysis of lactose to glucose and galactose gives rise to reactions that change the chemistry and quality of ambient-stored lactose-hydrolyzed ultra-high-temperature (UHT) milk. The aim of the present study was to investigate and compare chemical changes in lactose-hydrolyzed and conventional UHT milk during a 9 month ambient storage period. Several complementary analyses of volatiles, free amino acids, acetate, furosine, and level of free amino terminals were concluded. The analyses revealed an increased level of free amino acids and an increased formation rate of specific compounds such as furosine and 2-methylbutanal in lactose-hydrolyzed UHT milk compared to conventional UHT milk during storage. These observations indicate more favorable conditions for Maillard and subsequent reactions in lactose-hydrolyzed milk compared to conventional UHT milk stored at ambient temperature. Furthermore, it is postulated that proteolytic activity from the lactase-enzyme preparation may be responsible for the observed higher levels of free amino acids in lactose-hydrolyzed UHT milk.

Abstract
We have developed two parallel series, A and B, of CX3CR1 antagonists for the treatment of multiple sclerosis. By modifying the substituents on the 7-amino-5-thio-thiazolo[4,5-d]pyrimidine core structure, we were able to achieve compounds with high selectivity for CX3CR1 over the closely related CXCR2 receptor. The structure-activity relationships showed that a leucinol moiety attached to the core-structure in the 7-position together with α-methyl branched benzyl derivatives in the 5-position displayed promising affinity, and selectivity as well as physicochemical properties, as exemplified by compounds 18a and 24h. We show the preparation of the first potent and selective orally available CX3CR1 antagonists.
