A high sedentary time is associated with increased mortality risk. Previous studies indicate that replacement of sedentary time with light- and moderate-to-vigorous physical activity attenuates the ...risk for adverse outcomes and improves cardiovascular risk factors. Patients with cardiovascular disease are more sedentary compared to the general population, while daily time spent sedentary remains high following contemporary cardiac rehabilitation programmes. This clinical trial investigated the effectiveness of a sedentary behaviour intervention as a personalised secondary prevention strategy (SIT LESS) on changes in sedentary time among patients with coronary artery disease participating in cardiac rehabilitation.
Patients were randomised to usual care (n = 104) or SIT LESS (n = 108). Both groups received a comprehensive 12-week centre-based cardiac rehabilitation programme with face-to-face consultations and supervised exercise sessions, whereas SIT LESS participants additionally received a 12-week, nurse-delivered, hybrid behaviour change intervention in combination with a pocket-worn activity tracker connected to a smartphone application to continuously monitor sedentary time. Primary outcome was the change in device-based sedentary time between pre- to post-rehabilitation. Changes in sedentary time characteristics (prevalence of prolonged sedentary bouts and proportion of patients with sedentary time ≥ 9.5 h/day); time spent in light-intensity and moderate-to-vigorous physical activity; step count; quality of life; competencies for self-management; and cardiovascular risk score were assessed as secondary outcomes.
Patients (77% male) were 63 ± 10 years and primarily diagnosed with myocardial infarction (78%). Sedentary time decreased in SIT LESS (- 1.6 - 2.1 to - 1.1 hours/day) and controls (- 1.2 ─1.7 to - 0.8), but between group differences did not reach statistical significance (─0.4 ─1.0 to 0.3) hours/day). The post-rehabilitation proportion of patients with a sedentary time above the upper limit of normal (≥ 9.5 h/day) was significantly lower in SIT LESS versus controls (48% versus 72%, baseline-adjusted odds-ratio 0.4 (0.2-0.8)). No differences were observed in the other predefined secondary outcomes.
Among patients with coronary artery disease participating in cardiac rehabilitation, SIT LESS did not induce significantly greater reductions in sedentary time compared to controls, but delivery was feasible and a reduced odds of a sedentary time ≥ 9.5 h/day was observed.
Netherlands Trial Register: NL9263. Outcomes of the SIT LESS trial: changes in device-based sedentary time from pre-to post-cardiac rehabilitation (control group) and cardiac rehabilitation + SIT LESS (intervention group). SIT LESS reduced the odds of patients having a sedentary time >9.5 hours/day (upper limit of normal), although the absolute decrease in sedentary time did not significantly differ from controls. SIT LESS appears to be feasible, acceptable and potentially beneficial, but a larger cluster randomised trial is warranted to provide a more accurate estimate of its effects on sedentary time and clinical outcomes. CR: cardiac rehabilitation.
Both prenatal and postnatal parental bonding (i.e., the affective tie from parent to child) have important effects on parental and child functioning. However, research on the continuity and ...correlates of parental bonding is lacking. Therefore, the goal of the present study was to examine the stability of bonding levels and to explore distinct bonding patterns with a latent class analysis. Moreover, the correlates of these bonding patterns in the parental-, child-, and contextual domain were studied. Levels of maternal (N = 370) and paternal (N = 292) bonding and potential correlates were assessed at 26 weeks of pregnancy, 6 months, and 24 months postpartum. Results showed moderate stability of bonding from pregnancy to toddlerhood. For both mothers and fathers, 4 distinct bonding patterns were found. Parents with low bonding patterns were characterized by increased anxiety and parenting stress, less partner support, less adaptive personality profiles, and children with difficult temperament. These findings indicate the importance of monitoring young children's parents with poor levels of bonding as their bonding patterns remain stable from pregnancy until toddlerhood and because those parents experience problems in multiple domains.
Early executive functioning is an important predictor for future development of children’s cognitive skills and behavioral outcomes. Parenting behavior has proven to be a key environmental ...determinant of child executive functioning. However, the association of parental affect and cognitions directed to the child with child executive functioning has been understudied. Therefore, in the present study we examine the associations between parental bonding (i.e., the affective tie from parent to child), parenting stress, and child executive functioning. At 26 weeks of pregnancy, and at 6 months and 24 months postpartum the quality of the maternal (N = 335) and paternal (N = 261) bond with the infant was assessed. At 24 months, postnatal parenting stress and child executive functioning were measured by means of parent-report questionnaires. Results indicated that for both mothers and fathers feelings of bonding negatively predicted experienced parenting stress over time. In addition, for both parents a negative indirect effect of bonding on child executive functioning problems was found via experienced parenting stress. These findings indicate the importance of monitoring parents who experience a low level and quality of early parent-child bonding, as this makes them vulnerable to parenting stress, consequently putting their children at risk for developing executive functioning problems.
Objectives: To assess the contribution of out-of-home (OH) energy and nutrient intake to total dietary intake, and to compare out- versus in-home nutrient patterns among 27 centres in 10 countries ...participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Methods: Between 1995 and 2000, 36 034 participants aged between 35–74 years completed a standardized 24-h dietary recall using a software programme (EPIC-Soft) that recorded the place of food/drink consumption. Eating OH was defined as the consumption of foods and beverages anywhere other than in household premises, irrespective of the place of purchase/preparation. Nutrient intakes were estimated using a standardized nutrient database. Mean intakes were adjusted for age and weighted by season and day of recall. Results: Among women, OH eating contributed more to total fat intake than to intakes of protein and carbohydrates. Among both genders, and particularly in southern Europe, OH eating contributed more to sugar and starch intakes and less to total fibre intake. The contribution of OH eating was also lower for calcium and vitamin C intakes. The composition of diet at home was different from that consumed out of home in southern countries, but was relatively similar in the north. Conclusions: In northern Europe, OH and in-home eating are homogeneous, whereas southern Europeans consider OH eating as a distinctive occasion. In most centres, women selected more fat-rich items when eating out.
Objectives: To describe the contribution of highly processed foods to total diet, nutrient intakes and patterns among 27 redefined centres in the 10 countries participating in the European ...Prospective Investigation into Cancer and Nutrition (EPIC). Methods: Single 24-hour dietary recalls were collected from 36 034 individuals (aged 35-74 years) using a standardized computerized interview programme (EPIC-SOFT). Centre-specific mean food intakes (g/day) were computed according to their degree of food processing (that is, highly, moderately and non-processed foods) using a specifically designed classification system. The contribution (%) of highly processed foods to the centre mean intakes of diet and 26 nutrients (including energy) was estimated using a standardized nutrient database (ENDB). The effect of different possible confounders was also investigated. Results: Highly processed foods were an important source of the nutrients considered, contributing between 61% (Spain) and 78-79% (the Netherlands and Germany) of mean energy intakes. Only two nutrients, β-carotene (34-46%) and vitamin C (28-36%), had a contribution from highly processed foods below 50% in Nordic countries, in Germany, the Netherlands and the United Kingdom, whereas for the other nutrients, the contribution varied from 50 to 91% (excluding alcohol). In southern countries (Greece, Spain, Italy and France), the overall contribution of highly processed foods to nutrient intakes was lower and consisted largely of staple or basic foods (for example, bread, pasta/rice, milk, vegetable oils), whereas highly processed foods such as crisp bread, breakfast cereals, margarine and other commercial foods contributed more in Nordic and central European centres. Conclusions: Highly industrially processed foods dominate diets and nutrient patterns in Nordic and central European countries. The greater variations observed within southern countries may reflect both a larger contribution of non/moderately processed staple foods along with a move from traditional to more industrialized dietary patterns.
Background
Coronavirus disease 2019 (COVID-19) lockdown restrictions may impact lifestyle and therefore also physical (in)activity patterns in patients with cardiovascular disease (CVD). This study ...aimed to evaluate the effect of lockdown on physical activity and sedentary behaviour.
Methods
A total of 1565 Dutch CVD patients participated in this prospective cohort study, in which we compared physical activity and sedentary behaviour before and during the COVID-19 lockdown period. Baseline measures were assessed in 2018 and data on follow-up measures were collected between 17 and 24 April 2020 (5 weeks after the introduction of COVID-19 lockdown restrictions). Validated questionnaires were used to assess physical activity and sedentary behaviour.
Results
Moderate-to-vigorous physical activities increased from 1.6 (0.9, 2.8) to 2.0 (1.0, 3.5) h/day median (interquartile range) (
p
< 0.001) during the COVID-19 lockdown, mainly due to an increase in time spent walking and doing odd jobs. In contrast, time spent exercising significantly declined 1.0 (0.0, 2.3) to 0.0 (0.0, 0.6) h/week, whereas sedentary time increased from 7.8 (6.1, 10.4) to 8.9 (6.8, 11.4) h/day (
p
< 0.001). The absolute increase in physical activity was 13 (−36, 81) min/day, whereas sedentary behaviour increased by 55 (−72, 186) min/day.
Conclusion
Despite a small increase in physical activities, the larger increase in sedentary time induced a net reduction in habitual physical activity levels in Dutch CVD patients during the first-wave COVID-19 lockdown. Since a more inactive lifestyle is strongly associated with disease progression and mortality, we encourage CVD patients and their caregivers to explore novel solutions to increase physical activity levels and reduce sedentary time during (and beyond) the COVID-19 pandemic.
Organization of food services within hospitals has been identified as a determinant of hospitalized patients’ nutritional intake and associated food waste. Whereas hospital food service systems in ...the Netherlands traditionally consist of 3 fixed mealtimes each day, we recently implemented a new 3-channel concept that provides patients the opportunity to order extra meals or snacks in-between their 3 main mealtimes or even have dinner with their visitors in a bistro located on their ward.
This study investigates the impact of transitioning from a traditional paper-based to a patient-centered, digital hospital food service system on food waste production patterns and its associated financial implications.
Plate waste (served but uneaten food) measurements were performed at baseline for all served meals during a one-week period within the traditional system and follow-up measurements were conducted annually after implementation of the new system during 3 consecutive years. Measurements were conducted at two hospital floors, each comprising four wards. Average grams of plate waste per served meal, daily meal frequency per patient and the associated production and disposal costs of the collected waste were calculated and compared between the two systems.
A total of 4361 meals served within the traditional system were compared with 7815 meals served within the new digital system. Meal frequency increased from an average of 2.5 meals per patient per day in the old system to an average varying between 3 and 3.3 meals per patient per day in the consecutive years.
Within the traditional system, average plate waste was 81 grams per served meal, whilst it ranged between 33 and 49 grams per served meal during the following years, with the 3-channel concept in place (p < 0.001, p = 0.010). Dinner demonstrated the largest reduction in plate waste at all measurement points. Following this reduction of plate waste, estimated associated costs of plate waste production and disposal decreased in a similar pattern.
Transitioning from a traditional, paper based to a patient-centered and digital hospital catering system results in significantly higher daily meal frequency and less food waste per served meal.
In patients hospitalized for corona virus infectious disease 19 (COVID-19) it is currently unknown whether myocardial function changes after recovery and whether this is related to elevated cardiac ...biomarkers. In this single center, prospective cohort study we consecutively enrolled hospitalized COVID-19 patients between 1 April and 12 May 2020. All patients underwent transthoracic echocardiography (TTE) evaluation during hospitalization and at a median of 131 days (IQR; 116–136) follow-up. Of the 51 patients included at baseline, 40 (age: 62 years (IQR; 54–68), 78% male) were available for follow-up TTE. At baseline, 68% of the patients had a normal TTE, regarding left ventricular (LV) and right ventricular (RV) volumes and function, compared to 83% at follow-up (p = 0.07). Median LV ejection fraction (60% vs. 58%, p = 0.54) and tricuspid annular plane systolic excursion (23 vs 22 mm, p = 0.18) were comparable between hospitalization and follow-up, but a significantly lower RV diameter (39 vs. 34 mm, p = 0.002) and trend towards better global longitudinal strain (GLS) (− 18.5% vs − 19.1%, p = 0.07) was found at follow-up. Subgroup analysis showed no relation between patients with and without elevated TroponinT and/or NT-proBNP during hospitalization and myocardial function at follow-up. Although there were no significant differences in individual myocardial function parameters at 4 months follow-up compared to hospitalisation for COVID-19, there was an overall trend towards normalization in myocardial function, predominantly due to a higher rate of normal GLS at follow-up.
Wild ducks and gulls are the major reservoirs for avian influenza A viruses (AIVs). The mechanisms that drive AIV evolution are complex at sites where various duck and gull species from multiple ...flyways breed, winter, or stage. The Republic of Georgia is located at the intersection of three migratory flyways: the Central Asian flyway, the East Africa/West Asia flyway, and the Black Sea/Mediterranean flyway. For six complete study years (2010 to 2016), we collected AIV samples from various duck and gull species that breed, migrate, and overwinter in Georgia. We found a substantial subtype diversity of viruses that varied in prevalence from year to year. Low-pathogenic AIV (LPAIV) subtypes included H1N1, H2N3, H2N5, H2N7, H3N8, H4N2, H6N2, H7N3, H7N7, H9N1, H9N3, H10N4, H10N7, H11N1, H13N2, H13N6, H13N8, and H16N3, and two highly pathogenic AIVs (HPAIVs) belonging to clade 2.3.4.4, H5N5 and H5N8, were found. Whole-genome phylogenetic trees showed significant host species lineage restriction for nearly all gene segments and significant differences in observed reassortment rates, as defined by quantification of phylogenetic incongruence, and in nucleotide sequence diversity for LPAIVs among different host species. Hemagglutinin clade 2.3.4.4 H5N8 viruses, which circulated in Eurasia during 2014 and 2015, did not reassort, but analysis after their subsequent dissemination during 2016 and 2017 revealed reassortment in all gene segments except NP and NS. Some virus lineages appeared to be unrelated to AIVs in wild bird populations in other regions, with maintenance of local AIVs in Georgia, whereas other lineages showed considerable genetic interrelationships with viruses circulating in other parts of Eurasia and Africa, despite relative undersampling in the area.
Waterbirds (e.g., gulls and ducks) are natural reservoirs of avian influenza viruses (AIVs) and have been shown to mediate the dispersal of AIVs at intercontinental scales during seasonal migration. The segmented genome of influenza viruses enables viral RNA from different lineages to mix or reassort when two viruses infect the same host. Such reassortant viruses have been identified in most major human influenza pandemics and several poultry outbreaks. Despite their importance, we have only recently begun to understand AIV evolution and reassortment in their natural host reservoirs. This comprehensive study illustrates AIV evolutionary dynamics within a multihost ecosystem at a stopover site where three major migratory flyways intersect. Our analysis of this ecosystem over a 6-year period provides a snapshot of how these viruses are linked to global AIV populations. Understanding the evolution of AIVs in the natural host is imperative to mitigating both the risk of incursion into domestic poultry and the potential risk to mammalian hosts, including humans.
BackgroundRegular exercise training is an important factor in prevention of myocardial infarction (MI). However, little is known whether exercise engagement prior to MI is related to the magnitude of ...post-MI cardiac biomarker concentrations and clinical outcomes.ObjectivesWe tested the hypothesis that exercise engagement in the week prior MI is related to lower cardiac biomarker concentrations following ST-elevated MI (STEMI).MethodsWe recruited hospitalised STEMI patients and assessed the amount of exercise engagement in the 7 days preceding MI onset using a validated questionnaire. Patients were classified as ‘exercise’ if they performed any vigorous exercise in the week prior MI, or as ‘control’ if they did not. Post-MI peak concentrations of high-sensitive cardiac troponin T (peak-hs-cTnT) and creatine kinase (peak-CK) were examined. We also explored whether exercise engagement prior MI is related to the clinical course (duration of hospitalisation and incidence of in-hospital, 30-day and 6-month major adverse cardiac events (reinfarction, target vessel revascularisation, cardiogenic shock or death)).ResultsIn total, 98 STEMI patients were included, of which 16% (n=16) was classified as ‘exercise’, and 84% (n=82) as ‘control’. Post-MI peak-hs-cTnT and peak-CK concentrations were lower in the exercise group (941 (645–2925) ng/mL; 477 (346–1402) U/L, respectively) compared with controls (3136 (1553–4969) ng/mL, p=0.010; 1055 (596–2019) U/L, p=0.016, respectively). During follow-up, no significant differences were found between both groups.ConclusionEngagement in exercise is associated with lower cardiac biomarker peak concentrations following STEMI. These data could provide further support for the cardiovascular health benefits of exercise training.
