Vocal learning in songbirds: the role of syllable order in song recognition.

Funder: Dynamics of Youth (DoY) strategic research program of Utrecht UniversitySongbird vocal learning has interesting behavioural and neural parallels with speech acquisition in human infants. Zebra finch males sing one unique song that they imitate from conspecific males, and both sexes learn to recognize their father's song. Although males copy the stereotyped syllable sequence of their father's song, the role of sequential information in recognition remains unclear. Here, we investigated father's song recognition after changing the serial order of syllables (switching the middle syllables, first and last syllables, or playing all syllables in inverse order). Behavioural approach and call responses of adult male and female zebra finches to their father's versus unfamiliar songs in playback tests demonstrated significant recognition of father's song with all syllable-order manipulations. We then measured behavioural responses to normal versus inversed-order father's song. In line with our first results, the subjects did not differentiate between the two. Interestingly, when males' strength of song learning was taken into account, we found a significant correlation between song imitation scores and the approach responses to the father's song. These findings suggest that syllable sequence is not essential for recognition of father's song in zebra finches, but that it does affect responsiveness of males in proportion to the strength of vocal learning.

Dorpsverhalen:Samen bouwen aan de energietransitie in het Drentsche Aa- gebied

Dorpen in het Nationaal Park Drentsche Aa zijn zich bewust van de kwaliteit van hun omgeving. Tegelijkertijd werken deze dorpen aan lokale energieplannen. Daarbij worden veel resultaten gerealiseerd en lessen gedaan. Met zeven dorpen terug- en vooruitgekeken naar hun initiatieven zodat motieven, doelen, activiteiten (tijdlijn) en lessen konden worden opgetekend in deze publicatie

Immediate postoperative high-sensitivity troponin T concentrations and long-term patient-reported

BACKGROUND: Myocardial injury after noncardiac surgery is associated with mortality and major adverse postoperative cardiovascular events. The effect of postoperative troponin concentrations on patient-reported health-related quality of life (HRQoL) is unknown. OBJECTIVE: The study examined the association between immediate postoperative troponin concentrations and self-reported HRQoL 1 year after surgery. DESIGN: Prospective cohort study. SETTING: Single-centre tertiary care hospital in the Netherlands between July 2012 and 2015. PATIENTS: Patients aged at least 60 years undergoing moderate and major noncardiac surgery.None. MAIN OUTCOME MEASURES: HRQoL total score was assessed with the EuroQol five-dimensional questionnaire. Tobit regression analysis was used to determine the association between postoperative troponin concentrations and 1-year HRQoL. Peak high-sensitivity troponin T values were divided into four categories: less than 14, 14 to 49, 50 to 149 and at least 150 ng l. RESULTS: A total of 3085 patients with troponin measurements were included. 2634 (85.4%) patients were alive at 1-year follow-up of whom 1297 (49.2%) returned a completed questionnaire. The median score for HRQoL was 0.82 (0.85, 0.81, 0.77 and 0.71 per increasing troponin category). Multivariable analysis revealed betas of -0.06 [95% confidence interval (CI) -0.09 to -0.02], -0.11 (95% CI -0.18 to -0.04) and -0.18 (95% CI -0.29 to -0.07) for troponin levels of 14 to 49, 50 to 149 and at least 150 ng l when compared with values less than 14 ng l. Other independent predictors for lower HRQoL were chronic obstructive pulmonary disease, female sex, peripheral arterial disease and increasing age. CONCLUSION: Higher levels of postoperative troponin measured immediately after surgery were independently associated with lower self-reported HRQoL total score at 1-year follow-up

Postoperative troponin release is associated with major adverse cardiovascular events in the first year after noncardiac surgery

_Introduction:_ Troponin elevations after intermediate-to-high risk noncardiac surgery are common and can predict mortality. However, the prognostic value for early and late major adverse cardiovascular events (MACE) is less well investigated. The authors evaluated the relationship between postoperative troponin release and MACE in the first year after noncardiac surgery. _Methods:_ This observational cohort registry comprised data of patients aged ≥60 years undergoing intermediateto-high risk noncardiac surgery between July 2012 and 2015, at the Erasmus University Medical Center, Rotter

Gestational age and socio demographic factors associated with school performance at the age of 12 years, a population based study

BackgroundGestational age is positively associated with cognitive development, but socio-demographic factors also influence school performance. Previous studies suggested possible interaction, putting children with low socio-economic status (SES) at increased risk of the negative effects of prematurity.ObjectivesTo investigate the association between gestational age in weeks, socio-demographic characteristics, and school performance at the age of 12 years among children in regular primary education.MethodsPopulation-based cohort study among liveborn singletons (N = 860,332) born in the Netherlands in 1999–2006 at 25–42 weeks' gestation, with school performance from 2011 to 2019. Regression analyses were conducted investigating the association of gestational age and sociodemographic factors with school performance and possible interaction.ResultsSchool performance increased with gestational age up to 40 weeks. This pattern was evident across socio-demographic strata. Children born at 25 weeks had −0.57 SD (95% confidence interval −0.79, −0.35) lower school performance z-scores and lower secondary school level compared to 40 weeks. Low maternal education, low maternal age, and non-European origin were strongly associated with lower school performance. Being born third or later and low socioeconomic status (SES) were also associated with lower school performance, but differences were smaller than among other factors. When born preterm, children from mothers with low education level, low or high age, low SES or children born third or later were at higher risk for lower school performance compared to children of mothers with intermediate education level, aged 25–29 years, with intermediate SES or first borns (evidence of interaction).ConclusionsHigher gestational age is associated with better school performance at the age of 12 years along the entire spectrum of gestational age, beyond the cut-off of preterm birth and across socio-demographic differences. Children in socially or economically disadvantaged situations might be more vulnerable to the negative impact of preterm birth. Other important factors in school performance are maternal education, maternal age, ethnicity, birth order and SES. Results should be interpreted with caution due to differential loss to follow-up
