Locking Down Gender Roles? A Time-Use Perspective on Gender Division of Household Labour during the COVID-19 Pandemic Lockdown in Belgium.

The impact of the COVID-19 pandemic on the division of household labour could continue to lock down or start to break gender roles. Using time-use data of = 473 individuals collected during the lockdown restrictions in Belgium from March to May 2020, we analyse the gendered division of routine and non-routine household labour in absolute time use and relative shares. We compare against the Belgian time-use data of 2013 for the same time period ( = 678 individuals).

Graduate students locked down? PhD students' satisfaction with supervision during the first and second COVID-19 lockdown in Belgium.

Background: Supervisor support is crucial for the successful and timely completion of the PhD and the largest contributor to PhD students' overall job satisfaction. The COVID-19 pandemic affected PhD students' life substantially through delayed experiments, missed timelines, running out of funding, change to online team- and supervisor meetings, mandatory working from home, and social confinement.

Aim: This contribution considers PhD students' satisfaction scores to reflect the extent to which PhD students felt supported by their supervisor during the COVID-19 pandemic so far and aims to investigate to what extent did PhD students' satisfaction with supervisor support changed over time.

Standardised criteria for classifying the International Classification of Activities for Time-use Statistics (ICATUS) activity groups into sleep, sedentary behaviour, and physical activity.

Background: Globally, the International Classification of Activities for Time-Use Statistics (ICATUS) is one of the most widely used time-use classifications to identify time spent in various activities. Comprehensive 24-h activities that can be extracted from ICATUS provide possible implications for the use of time-use data in relation to activity-health associations; however, these activities are not classified in a way that makes such analysis feasible. This study, therefore, aimed to develop criteria for classifying ICATUS activities into sleep, sedentary behaviour (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA), based on expert assessment.

Testing compliance to WHO guidelines for physical activity in Flanders insights from time-use diaries.

Background: Regular physical activity decreases the risk for numerous non-communicable diseases. The World Health Organization has suggested physical activity (PA) guidelines that, based on previous research, would provide health benefits to those who comply. The first guideline for health benefits suggests 150 min of moderate PA or equivalent per week.

Active work, passive leisure? Associations between occupational and non-occupational physical activity on weekdays.

Research from recent years reports that physical inactivity is a major risk factor for global mortality. Several societal trends in the last decades are likely to have contributed to the increasing prevalence of sedentary lifestyles. Physical activity throughout the day has become much less self-evident and much more a matter of personal effort.

Earlier achievement of full enteral feeding in extremely low birth weight neonates is not associated with growth improvement in the first 2 years of life.

Unlabelled: Limiting the number of days until achievement of full enteral feeding in extremely low birth weight neonates (ELBW; < 1000 g) might affect growth in the first years of life. This study compared the Z scores in growth over time of two cohorts of ELBW neonates that were comparable on maternal and neonatal characteristics and characteristics of hospitalization, but differed in enteral feeding strategy during neonatal admission. In the 2010-2014 cohort, full enteral feeding was achieved on average 16 days earlier than in the 2000-2005 cohort.

Association between cognition and the retinal microvasculature in 11-year old children born preterm or at term.

Background: Retinal microvessels can be visualized non-invasively and mirror the status of the cerebral microvasculature.

Aims: To investigate whether in young children born prematurely or at term cognitive performance is related to retinal microvascular traits.

Study Design, Subjects: In 93 prematurely born infants (birth weight < 1000 g) and 87 controls born at term, we measured head circumference (HC) and determined intelligence quotient (IQ) by combining matrix reasoning and spatial span (Wechsler Non-Verbal test, Dutch version) and post-processed retinal photographs using Singapore I Vessel Assessment software (version 3.

Catch-up growth in the first two years of life in Extremely Low Birth Weight (ELBW) infants is associated with lower body fat in young adolescence.

Aim: To investigate growth patterns and anthropometrics in former extremely low birth weight (ELBW, <1000 g) children and link these outcomes to neurocognition and body composition in childhood.

Methods: ELBW children were examined at birth (n = 140), at 9 and 24 months (n≥96) and at approximately 11 years within the framework of the PREMATCH (PREMATurity as predictor children's of Cardiovascular and renal Health) case-control (n = 93-87) study. Regional growth charts were used to convert anthropometrics into Z-scores.

Does Extremely Low Birth Weight Predispose to Low-Renin Hypertension?

Unlabelled: Low birth weight and prematurity are risk factors for hypertension in adulthood. Few studies in preterm or full-term born children reported on plasma renin activity (PRA). We tested the hypothesis that renin might modulate the incidence of hypertension associated with prematurity.

Neonatal creatinemia trends as biomarker of subsequent cognitive outcome in extremely low birth weight neonates.

Background And Aims: Serum creatinine is traditionally used as a marker of renal function in neonates and relates to gestational age and disease severity in extremely low birth weight (ELBW) infants. Creatinine is commonly used as a biomarker for early morbidity, but we aim to compare postnatal creatinemia trends as a biomarker for subsequent cognitive outcome. We hypothesize that impaired microcirculation not only in the kidney, but also in general (i.

Convenience on the menu? A typological conceptualization of family food expenditures and food-related time patterns.

One of the most fundamental, but also controversial, food trends of the past years is convenience food. This article investigates the underexplored relationship between the heterogeneity in (convenience) food consumption (a feature of a food culture's cuisine) and meal patterns (characteristics of a food culture's structure). This study hopes to illustrate that convenience food can be interpreted both as a means to maintain a food culture's structure and as a means to overturn it.

Criteria for HNF1B analysis in patients with congenital abnormalities of kidney and urinary tract.

Background: Congenital anomalies of kidneys and urinary tract (CAKUT) are the most predominant developmental disorders comprising ∼20-30% of all anomalies identified in the prenatal period. Mutations in hepatocyte nuclear factor 1-beta (HNF-1β) involved in the development of kidneys, liver, pancreas and urogenital tract are currently the most frequent monogenetic cause of CAKUT found in 10-30% of patients depending on screening policy and study design. We aimed to validate criteria for analysis of HNF1B in a prospective cohort of paediatric and adult CAKUT patients.

Calculating the Social Rhythm Metric (SRM) and Examining Its Use in Interpersonal Social Rhythm Therapy (IPSRT) in a Healthy Population Study.

In psychiatry, the social zeitgeber theory argues that social life provides important social cues that entrain circadian rhythms. Disturbance of these social cues might lead do dis-entrainment of circadian rhythms and evoke somatic symptoms that increase the risk of mood disorders. In preventing and treating patients with bipolar disorders, the Interpersonal and Social Rhythm Therapy (IPSRT) relies on the Social Rhythm Metric (SRM) to (re)establish patients' social cues and an re-entrain circadian rhythms.

More than preparing a meal? Concerning the meanings of home cooking.

Cooking is one of the basic activities in our lives. However, people frequently feel they fall short of time to cook when facing problems with the temporal organization of daily life. How people think about home cooking is considered to be important for the time they spend on preparing meals.

The prognostic value of vascular endothelial growth factor in 574 node-negative breast cancer patients who did not receive adjuvant systemic therapy.

The growth and metastasising capacity of solid tumours are dependent on angiogenesis. Vascular endothelial growth factor is a mediator of angiogenesis. In this study we investigated whether vascular endothelial growth factor is associated with the natural course of the disease in primary invasive breast cancer.

Prognostic impact of urokinase-type plasminogen activator receptor (uPAR) in cytosols and pellet extracts derived from primary breast tumours.

Using a previously developed enzyme-linked immunosorbent assay (ELISA), the levels of the receptor for urokinase-type plasminogen activator (uPAR) were determined in cytosols and corresponding membrane pellets derived from 878 primary breast tumours. The levels of uPAR in the pellet extracts were more than 3-fold higher than those measured in the cytosols (P< 0.001).

Prognostic value of tissue-type plasminogen activator (tPA) and its complex with the type-1 inhibitor (PAI-1) in breast cancer.

The prognostic value of tissue-type plasminogen activator (tPA) measured in samples derived from 865 patients with primary breast cancer using a recently developed enzyme-linked immunosorbent assay (ELISA) was evaluated. Since the assay could easily be adapted to the assessment of the complex of tPA with its type-1 inhibitor (PAI-1), it was investigated whether the tPA:PAI-1 complex also provides prognostic information. To this end, cytosolic extracts and corresponding detergent extracts of 100,000 g pellets obtained after ultracentrifugation when preparing the cytosolic fractions for routine steroid hormone receptor determination were assayed.

Prognostic impact of urokinase-type plasminogen activator (uPA) and its inhibitor (PAI-1) in cytosols and pellet extracts derived from 892 breast cancer patients.

To evaluate the clinical relevance of urokinase-type plasminogen activator (uPA) and its type-1 inhibitor (PAI-1) measured by a recently developed enzyme-linked immunosorbent assay (ELISA), we analysed both components in samples derived from 892 patients with primary breast cancer (median follow-up 99 months). The assays were performed in cytosolic extracts as well as in corresponding detergent extracts of pellets obtained after ultracentrifugation, which was carried out when preparing the cytosolic fractions for routine steroid hormone receptor determination. Statistically significant correlations were found between the cytosolic levels and those determined in the pellet extracts (Spearman correlation coefficient r = 0.
