Antibiotic resistance of Enterobacteriaceae isolated from the domestic food related environments

Background: Multidrug resistant Enterobacteriaceae which was confined to the hospital environments is now emerging in the domestic food related environments as well. The main objective of the present study was to investigate the prevalence of antibiotic re-sistant Enterobacteriaceae in the domestic food related environments. Methods: Resistance to ampicillin, chloramphenicol, ciprofloxacin, gentamicin, tetracy-cline, nalidixic acid, nitrofurantoin, and trimethoprim was evaluated in 125 isolates; col-lected in domestic food related environments using agar micro dilution method. Results: Results indicated that 49.6% of the isolates were resistant to at least one antibi-otic (32.8% to ampicillin, 6.4% to nitrofurantoin, 4% to tetracycline, 3.2% to nalidixic acid, 2.4% to chloramphenicol and 1.7% to trimethoprim). Resistance to multiple antibi-otics was observed in 6.4% of the isolates. Conclusion: This study implicates existence of antibiotic resistant Enterobactericeae in the domestic food related environments. This resistance phenomenon requires continual vigilance; and further studies are required to evaluate the role of domestic surfaces in the transmission of resistant pathogens and spread of infectious diseases.info:eu-repo/semantics/publishedVersio

Semiclassical description of Heisenberg models via spin-coherent states

We use spin-coherent states as a time-dependent variational ansatz for a semiclassical description of a large family of Heisenberg models. In addition to common approaches we also evaluate the square variance of the Hamiltonian in terms of coherent states. This quantity turns out to have a natural interpretation with respect to time-dependent solutions of the equations of motion and allows for an estimate of quantum fluctuations in a semiclassical regime. The general results are applied to solitons, instantons and vortices in several one- and two-dimensional models.Comment: 14 page

Can the Visits of Dogs (Canis lupus familiaris) Influence the Mental Health (Anxiety and Depression) of Male Aging Patients Institutionalized with Dementia in Health Care Units? A Pilot Study of Madeira Island, Portugal

Despite the fact that in the last decades, several mental health studies have shown that companion animals contribute to psychological and social well-being in humans (e.g., posi tive impacts have been observed in the elderly medicated for chronic diseases such as anxiety, dementia, and depression), bonds between humans and other animals continue to be under estimated. The aim of this study is to assess the impact of an animal’s visits (twice a week, N = 30) in depression and anxiety levels of an institutionalized male population diagnosed with de mentia. While some of these patients are being partially medicated with antidepressants and/or anxiolytics, others are not subject to any medication (control group). The GAI and GDS measur ing instruments were used and there were differences in anxiety and depression levels between the first and last dog visit, statistically significant in depression levels of nonmedicated patients. Such findings allow us to conclude that the effects of the visits of an animal near nonmedicated patients are greater than near medicated ones. The complementary role of animals in mental health institutions where patients are being treated for psychiatric disorders (in the particular case of dementia) should be considered.info:eu-repo/semantics/publishedVersio
