RESUMEN
AIMS: To discover the reasons behind invited families' lack of engagement with a family-based childhood obesity programme in a deprived area. METHODS: Interviews were conducted with 10 families who were invited to join the programme, but declined to engage. There were two distinct subgroups of participants: those who had no interest in attending the programme and those who showed initial interest yet did not continue attending. The two subgroups were analyzed separately using inductive thematic analysis, and then compared. RESULTS: Analysis identified eight themes overall. For both groups, when the service was perceived to be not needed ('I didn't see how that would help'), the families disengaged with it. For both groups, this perception was partly related to the perceived appearance of their children: either that they were not obese ('I didn't think my son was overweight') or that they were growing into their size. There was also a similarity in both groups that they perceived that they were already following healthy lifestyles. In addition, several of the themes arising from the families who had no initial interest were related to the impact of the letter that parents received detailing the result of their child being weighed and measured at school. This angered parents ('I was disgusted'), and there was a feeling that the approach was too generic. CONCLUSION: This study identified a number of potential reasons behind why families may decline to engage with a childhood obesity programme in a deprived area. Across all families, if the programme was perceived as not needed, they would disengage. For those who did not engage at all, the initial communication of the child's body mass index (BMI) is crucial. Recommendations include taking a more personal and tailored approach for the initial communication and shifting the focus of the programmes onto healthier lifestyles.

Enterococci, already know to be relatively unaffected by several antibiotics due to their inheritant characteristics, are increasingly resistant to some very important groups of drugs, by means of acquisition or exchange of new genetic traits of resistance. Resistance or moderate susceptibility towards penicillin is an interesting characteristic of enterococci, whose low degree of susceptibility to this drug is due to a low affinity for penicillin-binding proteins (PBP). Some strains of enterococci are not killed by the action of this drug but are "tolerant" (MIC/MBC > 32 mg/l). This kind of "resistance", in which the probability of surviving under selective pressure of the drug is increased, is probably linked to the deficiency of the cell's autolytic system. Only rarely does another form of resistance called the "paradoxical effect" appear, in which higher numbers of cells survive at high concentrations than at lower concentrations. In our study the degree of bactericidal activity of some beta-lactams was considered. Our results demonstrate that: i) the paradoxical effect appears more in cultures in exponential phase compared to aged cultures; ii) mutated strains show an increased number of cells that respond paradoxically (the behavior is genetically determined); iii) different beta-lactams induced different degrees of autolysis.
