    BACKGROUND: Maternal smoking during pregnancy (MSDP) is associated with multiple adverse childhood outcomes including externalizing behaviors. However, the association between MSDP and internalizing (anxiety and depressive) behaviors in offspring has received less investigation. We aimed to assess the association between MSDP and childhood internalizing (anxiety and depressive) behaviors in a very large, well-characterized cohort study. METHODS: We assessed the association between MSDP and internalizing behaviors in offspring utilizing information drawn from 90,040 mother-child pairs enrolled in the Norwegian Mother and Child Cohort Study. Mothers reported smoking information, including status and frequency of smoking, twice during pregnancy. Mothers also reported their child\u27s internalizing behaviors at 18 months, 36 months, and 5 years. Associations between MSDP and childhood internalizing behaviors, including dose-response and timing of smoking in pregnancy, were assessed at each time point. RESULTS: MSDP was associated with increased internalizing behaviors when offspring were aged 18 months (B = 0.11, P <0.001) and 36 months (B = 0.06, P <0.01), adjusting for numerous potential confounders. Higher rates of smoking (e.g., >20 cigarettes per day) were associated with higher levels of internalizing behaviors. Maternal smoking during early pregnancy appeared to be the critical period for exposure. CONCLUSIONS: We found evidence supporting a potential role for MSDP in increasing internalizing (anxiety and depressive) behaviors in offspring. We also found evidence supportive of a possible causal relationship, including dose-dependency and support for a predominant role of early pregnancy exposure. Further investigation utilizing genetically informed designs are warranted to assess this association

    Mortality following first-time hospitalization with acute myocardial infarction in Norway, 2001-2014: Time trends, underlying causes and place of death

    Background Trends on cause-specific mortality following acute myocardial infarction (AMI) are poorly described and no studies have analyzed where do AMI patients die. We analyzed trends in 28-day and one-year mortality following an incident AMI with focus on changes over time in the underlying cause and place of death. Methods We identified in the ‘Cardiovascular Disease in Norway’ Project all patients 25+ years, hospitalized with an incident AMI in Norway, 2001–2014. Information on date, underlying cause and place of death was obtained from the Cause of Death Registry. Results Of 144,473 patients included in the study, 11.4% died within first 28 days. The adjusted 28-day mortality declined by 5.2% per year (ptrend < 0.001). Of 118,881 patients surviving first 28 days, 10.1% died within one year. The adjusted one-year CVD mortality declined by 6.2% per year (ptrend < 0.001) while non-CVD mortality increased by 1.4% per year (ptrend < 0.001), mainly influenced by increased risk of dying from neoplasms. We observed a shift over time in the underlying cause of death toward more non-CVD deaths, and in the place of death toward more deaths occurring in nursing homes. Conclusions We observed a decline in 28-day mortality following an incident AMI hospitalization. One-year CVD mortality declined while one-year risk of dying from non-CVD conditions increased. The resulting shift toward more non-CVD deaths and deaths occurring outside a hospital need to be considered when formulating priorities in treating and preventing adverse events among AMI survivors.acceptedVersio

    Postponed access until 23rd October 2020.Aims To examine trends in heart failure (HF) hospitalization rates and risk of readmissions following an incident HF hospitalization. Methods and results During 2000–2014, we identified in the Cardiovascular Disease in Norway Project 142 109 hospitalizations with HF as primary diagnosis. Trends of incident and total (incident and recurrent) HF hospitalization rates were analysed using negative binomial regression models. Changes over time in 30-day and 3-year risk of HF recurrences or cardiovascular disease (CVD)-related readmissions were analysed using Fine and Grey competing risk regression, with death as competing events. Age-standardized rates declined on average 1.9% per year in men and 1.8% per year in women for incident HF hospitalizations (both Ptrend < 0.001) but did not change significantly in either men or women for total HF hospitalizations. In men surviving the incident HF hospitalization, 30-day and 3-year risk of a HF recurrent event increased 1.7% and 1.2% per year, respectively. Similarly, 30-day and 3-year risk of a CVD-related hospitalization increased 1.5% and 1.0% per year, respectively (all Ptrend < 0.001). No statistically significant changes in the risk of HF recurrences or CVD-related readmissions were observed among women. In-hospital mortality for a first and recurrent HF episode declined over time in both men and women. Conclusions Incident HF hospitalization rates declined in Norway during 2000–2014. An increase in the risk of recurrences in the context of reduced in-hospital mortality following an incident and recurrent HF hospitalization led to flat trends of total HF hospitalization rates.acceptedVersio

    A meta-analysis to determine factors associated with the severity of enteritis in Atlantic salmon (Salmo salar) fed soybean meal-based diets

    A meta-analytic approach was used to determine factors associated with the severity of enteritis in distal intestine of Atlantic salmon fed soybean meal (SBM)-based diets. Dataset from 26 fish studies were extracted and standardized for use in the meta-analysis. After standardization, the data were analyzed with ordinal logistic regression model by comparing the SBM treatment(s) in each study with the neutral-reference treatment. The log-odds ratio of the proportional odds model and its standard error were extracted and analyzed using the random effects model to estimate the effect size of dietary SBM on enteritis using four semi-quantitative histological variables: reduction in mucosal fold height; disappearance of supranuclear vacuolization; inflammatory cell infiltration of lamina propria, and of submucosa. Both univariate and multivariate meta-regression were used to identify study factors with significant association to the severity of enteritis in Atlantic salmon. The results showed that fish production phase, feed type, SBM inclusion level, year of study and water temperature are significantly associated with the severity of enteritis in Atlantic salmon. Further meta-analysis of sub datasets according to production phase, revealed that fish reared in seawater were more prone to develop enteritis compared with fish reared in freshwater. The absence of positive relationship between SBM inclusion level and the severity of enteritis was probably due to difference in source, batch, processing, and level of anti-nutritional factors in the SBM used in the different studies combined in the meta-analysis. Subgroup analysis based on year of study revealed that the severity of enteritis in fish fed SBM-based diets has decreased over the years. Additional results revealed that fish fed SBM-based diet at low water temperature showed increased severity of enteritis, compared with fish raised in high water temperature. Linear and quadratic regressions conducted to explore possible impact of enteritis on fish performance, showed that the specific growth rate and thermal growth coefficient of fish decreased with increased severity of enteritis. However, this relationship depends on the fish production phase and the histological variables used for the regression analysis. The current study concluded that the severity of enteritis in Atlantic salmon fed SBM-based diets are significantly associated with fish production phase, feed type, SBM inclusion level, year of study and water temperature, but not the exposure time. Also, the study showed that increased severity of enteritis reduced specific growth rate and thermal growth coefficient of fish fed SBM-based diets.A meta-analysis to determine factors associated with the severity of enteritis in Atlantic salmon (Salmo salar) fed soybean meal-based dietspublishedVersio

    This study investigated morphological changes associated with soya bean meal-induced enteritis (SBMIE) in distal intestine (DI) of rainbow trout (Oncorhynchus mykiss) fed a soya bean meal (SBM)-based diet and exposed to normoxia or hypoxia created by optimal and low water flow rates, respectively. A 28-day adaption period was followed by a 42-day challenge period where 600 fish were subjected to dietary challenge and/or hypoxia. Twelve tanks each containing 50 juvenile trout were assigned randomly in triplicate to each treatment. Histopathological and immunohistochemical evaluation revealed pathological features that have not previously been described in association with SBMIE. Vacuolar degeneration of epithelial cells mainly at the base of mucosal folds, epithelial cysts, epithelial dysplasia, necrosis, shedding of necrotic cells, and granulomatous inflammation including infiltration of enlarged, sometimes finely vacuolated or “foamy” macrophages, multinucleated giant cells and increased proliferation of fibroblasts were observed. Acid-fast bacteria were not detected in enlarged macrophages; however, these cells contained AB-PAS- and sometimes cytokeratin-positive material, which was interpreted to be of epithelial/goblet cell origin. Hypoxia did not affect the morphological changes in DI. These results suggest that SBM was associated with a granulomatous form of enteritis in DI of rainbow trout regardless of water oxygen level

    Cumulative contributions of social and health-related determinants to long-term unemployment during early working life among young adults are poorly understood. Therefore, we used four cumulative indices of both parental and own social and health-related determinants of such unemployment among a cohort which comprised a complete census of children born in Finland in 1987. The cohort participants were registered in the Medical Birth Register, and they were followed-up through 2015 (N = 46 521). We calculated predicted probabilities for long-term unemployment (> 12 months) when participants were 25–28 years. Moreover, we examined whether the associations differed by unemployment at the municipal level.During the follow-up, 4.5% of women and 7.1% of men experienced long-term unemployment. All cumulative indices of parental and own social and health-related determinants predicted the probability of long-term unemployment. The greatest probabilities were observed for own social determinants, both in municipalities with high and low unemployment although the probabilities were higher in the high-unemployment municipalities. Of the individual determinants, poor school performance showed the strongest association with long-term unemployment among women (OR 6.65, 95% CI 5.21–8.55) and men (OR 3.70, 95% CI 2.96–4.67), after adjusting for other own social determinants. The results highlight the importance of life course social equality in the prevention of long-term unemployment in early adulthood.</p

    A SWOT Analysis of the Use of Marine, Grain, Terrestrial-Animal and Novel Protein Ingredients in Aquaculture Feeds

    Get PDF
    A variety of new feed ingredients are emerging in the aquaculture feed sector. While the technology readiness of these options varies across and within the new ingredient classes, it remains important to consider them in terms of the overall feed ingredient spectrum. In this review, the use of marine, grain, terrestrial animal by-product and a range of novel (e.g., bacterial and yeast) resources being considered as potential protein feedstuffs for use in aquafeeds is explored. In comparing the nutritional attributes of each of the ingredient classes, an assessment framework is applied based on understanding the critical knowledge required to be able to accommodate any ingredient in a formulation process. To further examine each of the different ingredient classes a Strength-Weakness-Opportunity-and-Threats (SWOT) analysis is applied, to enable some consideration of what future potential may exist across the spectrum and what risks and opportunities they may bring. It is noted that all ingredients have strengths and weaknesses, and that there is no such thing as the perfect ingredient. By better appreciating the positives and negatives of each ingredient, it becomes possible to increase adaptability in responding to the various opportunities for their use in feeds
