Exploring EEG resting state as a function of boredom proneness in pre-adolescents and adolescents.

Boredom is a prominent experience commonly reported in school settings and associated with poor academic achievement. Little is known, however, about the age-related trajectory of boredom. Here we examined self-reported ratings of boredom in a cross-sectional sample of 8 to 15-year olds (n = 185) as a function of resting state EEG. Results indicated that reports of boredom in school rose as a function of age. Resting state EEG showed a decrease in theta power with age perhaps reflective of increased control. While no effects were evident in beta and alpha bands, we did observe an interaction between boredom and age for frontal asymmetry such that for those higher in boredom, the asymmetry increased with age. Finally, for theta to beta ratios there were main effects of age (i.e., a decrease in theta/beta ratio with age) and boredom such that those higher in boredom had higher theta/beta ratios over frontal and central brain areas. The results are discussed in the context of prior work on school-related boredom and provide several important avenues for further research.

Susceptibility pattern of tracheal tube isolates from Intensive Care Unit of Fauji Foundation Hospital Rawalpindi.

OBJECTIVE: To determine the prevalence of resistant pathogens and their antimicrobial susceptibility pattern in an intensive care unit. METHODS: The cross-sectional observational study was conducted at Foundation Hospital, Rawalpindi, Pakistan, from May to September 2016, and comprised tracheal tubes which were collected in sputum culture bottles from patients with clinical findings of ventilator associated pneumonia. The tubes were cultured to locate the resistant pathogens. RESULTS: A total of 113 different strains of bacteria were isolated from 80 patients. The main isolated bacteria was acinetobacter baumannii 45(39.8%) followed by klebsiella pneumonia 14(12.3%) and methicillin-resistant staphylococcus aureus 13(11.5%). Polymyxin B was the most appropriate drug for treating patients infected with acinetobacter baumannii with a sensitivity of 64% while vancomycin and linez oli dhad 100% sensitivity for methicill in - resistant staphylococcusaureus. CONCLUSIONS: Acinetobacter baumannii was the most prevalent strain in tracheal tubes and polymyxin B was the most effective medicine.
