A randomized controlled trial for overweight and obesity in preschoolers: the More and Less Europe study- an intervention within the STOP project
Background Childhood overweight and obesity is a serious public health issue with an increase being observed in preschool-aged children. Treating childhood obesity is difficult and few countries use standardized treatments. Therefore, there is a need to find effective approaches that are feasible for both health care providers and families. Thus, the overall aim of this study is to assess the acceptance and effectiveness of a parent support program (the More and Less, ML) for the management of overweight and obesity followed by a mobile health (mHealth) program (the MINISTOP application) in a socially diverse population of families. Methods/design A two-arm, parallel design randomized controlled trial in 300 2-to 6-year-old children with overweight and obesity from Romania, Spain and Sweden (nâ=â100 from each). Following baseline assessments children are randomized into the intervention or control group in a 1:1 ratio. The intervention, the ML program, consists of 10-weekly group sessions which focus on evidence-based parenting practices, followed by the previously validated MINISTOP application for 6-months to support healthy eating and physical activity behaviors. The primary outcome is change in body mass index (BMI) z-score after 9-months and secondary outcomes include: waist circumference, eating behavior (Child Eating Behavior Questionnaire), parenting behavior (Comprehensive Feeding Practices Questionnaire), physical activity (ActiGraph wGT3x-BT), dietary patterns (based on metabolic markers from urine and 24âh dietary recalls), epigenetic and gut hormones (fasting blood samples), and the overall acceptance of the overweight and obesity management in young children (semi-structured interviews). Outcomes are measured at baseline and after: 10-weeks (only BMI z-score, waist circumference), 9-months (all outcomes), 15- and 21-months (all outcomes except physical activity, dietary patterns, epigenetics and gut hormones) post-baseline. Discussion This study will evaluate a parent support program for weight management in young children in three European countries. To boost the effect of the ML program the families will be supported by an app for 6-months. If the program is found to be effective, it has the potential to be implemented into routine care to reduce overweight and obesity in young children and the app could prove to be a viable option for sustained effects of the care provided.

Over-subscription planning with Boolean optimization: an assessment of state-of-the-art solutions
In this work we present an assessment of state-of-the-art Boolean optimization solvers from different AI communities on over-subscription planning problems. The goal of the empirical analysis here presented is to assess the current respective performance of a wide variety of Boolean optimization solvers for solving such problems

Explaining the complex impact of the Covid-19 pandemic on children with overweight and obesity : a comparative ecological analysis of parentsâ perceptions in three countries
Background
The Covid-19 pandemic has changed childrenâs eating and physical activity behaviours. These changes have been positive for some households and negative for others, revealing health inequalities that have ramifications for childhood obesity. This study investigates the pandemicâs impact on families of children aged 2â6âyears with overweight or obesity.
Methods
Drawing on interviews conducted as part of a randomised controlled trial (RCT) for childhood obesity, thematic analysis was used to examine how parents of pre-schoolers perceived changes in their eating, screentime and physical activity behaviours between the first and second waves of Covid-19. Parents (n =â70, representing 68 families) were interviewed twice during a period of 6âmonths in three countries with markedly different pandemic policies â Sweden, Romania, and Spain. The analysis is informed by Bronfenbrennerâs ecological systems theory, which embeds home- and school-based influences within societal and policy contexts.
Results
The findings show that, although all participants were recruited from an RCT for families of children with excess weight, they reported different responses to the pandemicâs second wave, with some children engaging in healthier eating and physical activity, and others engaging in comfort eating and a more sedentary lifestyle. Differences in childrenâs obesity-related behaviours were closely related to differences in parentsâ practices, which were, in turn, linked to their emotional and social wellbeing. Notably, across all sites, parentsâ feeding and physical activity facilitation practices, as well as their emotional and social wellbeing, were embedded in household resilience. In resilient households, where parents had secure housing and employment, they were better able to adapt to the challenges posed by the pandemic, whereas parents who experienced household insecurity found it more difficult to cope.
Conclusions
As the Covid-19 pandemic is turning into a long-term public health challenge, studies that address household resilience are crucial for developing effective prevention and treatment responses to childhood obesity
On Reducing Maximum Independent Set to Minimum Satisfiability
Abstract. Maximum Independent Set (MIS) is a well-known NP-hard graph problem, tightly related with other well known NP-hard graph problems, namely Minimum Vertex Cover (MVC) and Maximum Clique (MaxClq). This paper in-troduces a novel reduction of MIS into Minimum Satisfiability (MinSAT), thus, providing an alternative approach for solving MIS. The reduction naturally maps the vertices of a graph into clauses, without requiring the inclusion of hard clauses. Moreover, it is shown that the proposed reduction uses fewer variables and clauses than the existing alternative of mapping MIS into Maximum Satisfiability (Max-SAT). The paper develops a number of optimizations to the basic reduction, which significantly reduce the total number of variables used. The experimental evalu-ation considered the reductions described in the paper as well as existing state-of-the-art approaches. The results show that the proposed approaches based on MinSAT are competitive with existing approaches.
Safety and efficacy of prolonged use of dalbavancin in bone and joint infections
Dalbavancin is a lipoglycopeptide with potent activity against Gram-positive microorganisms, a long half-life, a favorable safety profile, and a high concentration in bone, which makes it an interesting alternative for treatment of osteoarticular infections. We performed a multicentric retrospective study of all patients with an osteoarticular infection (septic arthritis, spondylodiscitis, osteomyelitis, or orthopedic implant-related infection) treated with at least one dose of dalbavancin between 2016 and 2017 in 30 institutions in Spain. In order to evaluate the response, patients with or without an orthopedic implant were separated. A total of 64 patients were included. Staphylococcus epidermidis and Staphylococcus aureus were the most frequent microorganisms. The reasons for switching to dalbavancin were simplification (53.1%), adverse events (25%), or failure (21.9%). There were 7 adverse events, and no patient had to discontinue dalbavancin. In 45 cases, infection was related to an orthopedic implant. The implant material was retained in 23 cases, including that in 15 (65.2%) patients that were classified as cured and 8 (34.8%) that presented improvement. In 21 cases, the implants were removed, including those in 16 (76.2%) cases that were considered successes, 4 (19%) cases were considered improved, and 1 (4.8%) case that was considered a failure. Among the 19 cases without implants, 14 (73.7%) were considered cured, 3 (15.8%) were considered improved, and 2 (10.5%) were considered failures. The results show that dalbavancin is a well-tolerated antibiotic, even when 2 doses are administered, and is associated with a high cure rate. These are preliminary data with a short follow-up; therefore, it is necessary to gain more experience and, in the future, to establish the most appropriate dose and frequency.This study was supported by the Bone and Joint Infection Study Group (SGR 253) of the AgĂšncia de GestiĂł dâAjuts Universitaris I de Recerca (AGAUR) and by the Red Española de InvestigaciĂłn en PatologĂa Infecciosa (REIPI).
