El bullying, lamentablemente, no es un tema nuevo en el ámbito educativo. Sin embargo, con la introducción de las nuevas tecnologías en nuestras vidas, una nueva forma de acoso ha cobrado protagonismo más allá de las aulas: el ciberbullying.

Background: The relevance of persistent cognitive deficits to the pathogenesis and prognosis of bipolar disorders (BD) is understudied, and its translation into clinical practice has been limited by the absence of brief methods assessing cognitive status in Psychiatry. This investigation assessed the psychometric properties of the Spanish version of the Screen for Cognitive Impairment in Psychiatry (SCIP-S) for the detection of cognitive impairment in BD. Methods: After short training, psychiatrists at 40 outpatient clinics administered the SCIP three times over two weeks to a total of 76 consecutive type I BD admissions. Experienced psychologists also administered a comprehensive battery of standard neuropsychological instruments to clinical sample and 45 healthy control subjects. Results: Feasibility was supported by a brief administration time (approximately 15 minutes) and minimal scoring errors. The reliability of the SCIP was confirmed by good equivalence of forms, acceptable stability (ICC range 0.59 to 0.87) and adequate internal consistency (Chronbach's alpha of 0.74). Construct validity was granted by extraction of a single factor (accounting 52% of the variance), acceptable correlations with conventional neuropsychological instruments, and a clear differentiation between bipolar I and normal samples. Efficiency was also provided by the adequate sensitivity and specificity. Limitations: The sample size is not very large. The SCIP and the neurocognitive battery do not cover all potentially relevant cognitive domains. Also, sensitivity to change remains unexplored. Conclusion: With minimal training, physicians obtained a reliable and valid estimate of cognitive impairment in approximately 15 minutes from an application of the SCIP to type I BD patients.

Ozonization of theobroma oil at different applied ozone dosages was carried out with measurement of peroxide index values, oxygen percentage content and fatty acids composition. The comparison of peroxide values with percentage content of oxygen at different applied ozone dosages showed good correlation (r=0.9923). Unsaturated fatty acids and triacylglycerols decrease with ozone applied dosage due to ozone reaction with double bonds. Small amounts of oleic acid were consumed with applied ozone dosage at 35 mg/g, which demonstrated that peroxide values and oxygen content were not principally increased by the ozone attack on the double bonds, but other mechanisms could be involved in the reaction system.

Ozonation of sunflower oils with genetic modification High Oleic and High Oleic-Palmitic (AO and PO respectively) and without modification, High Linoleic (AL) at different applied ozone dosages was carried out with measurement of peroxide and acidity indexes values, fatty acids composition, oxygen percentage content and antimicrobial activity. The comparison of peroxides indexes and oxygen content at different applied ozone dosages in each oil showed good correlation (r = 0,99). Higher amount of oleic acid was consumed at higher applied ozone dosage in PO oil than AO oil, which can be related to the increase of acidity index. The antimicrobial activity was better for AL and PO ozonized oils.
