ABSTRACT
A combined gas chromatography-mass spectrometry approach has been used for the characterization of two lumps of resin and 17 adsorbed residues on Roman-age vessels, mainly amphorae, from northern Greece. The data show that a diterpenic resin from plants of the Pinacae family is the main component of the tarry material associated with the analyzed archaeological samples. The identification and mass spectrometric fragmentation of several characteristic diterpenoid biomarkers is discussed. The abundance of secondary products identified in the archaeological samples suggests that the oxidative degradation of abietic acid and dehydroabietic acid to aromatic products was the main pathway. Of particular interest is the presence of characteristic saturated abietane hydrocarbons in one sample, which indicate that a reductive process also occurred on a small scale. The overall similarity in the composition of the residues suggests the common use of pine tar as a waterproofing and sealing agent at different sites in northern Greece during the Roman period.
ABSTRACT
PURPOSE: The aim was to study the influence of patients' age, frequency and type of seizures, disease duration, number of AEDs and use of benzodiazepines on the quality of life of patients with epilepsy. PATIENTS AND METHODS: We consecutively identified 223 patients with epilepsy who attended the epilepsy outpatient clinics at three university hospitals in Greece. Quality of life was evaluated by QOLIE-31. One-way analysis was used to assess the association of the studied factors and QOLIE-31 subscales. After checking for co-linearity, we performed multivariate stepwise linear regression analysis with all the variables that on univariate analysis showed a statistically significant effect on each subscale of QOLIE-31 to explore which of the studied factors affect independently on QOLIE-31 scores. RESULTS: Of a total of 223 patients, 118 (52.95%) were men; mean age was 35.18 +/- 13.22; mean duration of the disease was 13 years; 58 (26%) patients had generalized seizures, 93 (41.7%) had PS, and 72 (32.3%) of the patients had PsG; 85 (38.1%) were on polytherapy and 38 (17%) were taking benzodiazepines. Independent factors affecting QoL were: seizure frequency (Overall QoL P = 0.0001, Seizure worry and Emotional well-being P < 0.0001, Energy/fatigue and Social functioning P = 0.01); duration of the disease (Overall QoL and Energy/fatigue P = 0.01, Seizure worry P = 0.008, Cognitive functioning P < 0.0001); polytherapy only for the Emotional well-being P < 0.0001; and use of benzodiazepines (Overall QoL, Energy/fatigue, Social functioning P = 0.002, Cognitive functioning P < 0.0001). CONCLUSION: Our findings suggest that QoL in epileptic patients might be affected, in addition to the other established factors (high frequency of seizures and polytherapy), by the daily use of benzodiazepines as adjunctive therapy. Change of medical strategy concerning this medication may lead to improving the QoL of these patients.
