In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: To evaluate the superiority of transcutaneous oxygen pressure (TcPO2) before, during and after peripheral transluminal angioplasty (PTA) in comparison with ankle brachial index (ABI) in patients with diabetes.', '40 consecutive patients with diabetes treated by PTA where included. This study shows results before, during and after PTA and their progression for 8 weeks.', 'The TcPO2 increased from 28.118.1 to 48.038.4mmHg, 8 weeks after PTA (p<0.001). The ABI increased from 0.480.38 to 0.770.39 after PTA (p<0.001). After PTA, the stenosis of the vessel decreased from 58.3320.07% to 21.8713.57% (p<0.001). TcPO2 was determined in all the patients, but ABI could not be determined in all patients. Furthermore, we determined patients with "false negatives" with an improvement in ABI and "false positives" in 12.5% of patients. Additionally, in this study, we monitored TcPO2 while performing PTA, revealing variations in each phase of the radiological procedure.\Question: Does transcutaneous oxygen tension measurements following peripheral transluminal angioplasty procedure have more specificity and sensitivity than ankle brachial index?
The increase in TcPO2 measurements following PTA procedure has more specificity and sensitivity than does ABI. The use of TcPO2 may represent a more accurate alternative than traditional methods (ABI) used in assessing PTA results. The TcPO2 also allows the radiologist to assess changes in tissue oxygenation during PTA, allowing changes to the procedure and subsequent treatment.

Context: The present study investigated the effects of continuous theta-burst stimulation (cTBS) over primary somatosensory (SI) and motor (M1) cortices on motor-evoked potentials (MEPs) and short-latency afferent inhibition (SAI).', 'MEPs and SAI were recorded from the first dorsal interosseous (FDI) muscle of the right hand following 30Hz cTBS over left-hemisphere SI and M1 delivered to the same participants in separate sessions. Measurements were taken before and up to 60min following cTBS.', 'CTBS over M1 suppressed MEPs and did not alter SAI. In contrast cTBS over SI facilitated MEPs and decreased median and digital nerve evoked SAI.\Question: Does continuous theta-burst stimulation over primary somatosensory cortex modulate short-latency afferent inhibition?
These findings indicate that SAI amplitude is influenced by cTBS over SI but not M1, suggesting an important role for SI in the modulation of this circuit. These data provide further evidence that cTBS over SI versus M1 has opposite effects on corticospinal excitability.

Context: To assess the association between the intake of dietary fibre and carotid intima-media thickness (IMT) in a Mediterranean population at high cardiovascular risk.', 'Baseline cross-sectional assessment of 457 men and women (average age 67 years) from two different Spanish centres of the PREDIMED trial. A previously validated food frequency questionnaire (137 food items) was administered by trained dieticians in a face-to-face interview. Mean common carotid IMT was measured using B-mode ultrasound imaging of the right and left carotid arteries by four certified sonographers who used a common protocol. Anthropometric and blood pressure measurements were performed and samples of fasting blood were obtained. Participants were categorized into four groups (roughly quartiles: < or =21; >21 to < or =25; >25 to < or =31 and >31 g/day) of energy-adjusted intake of dietary fibre. Multiple linear regression models were used to adjust for age, sex, centre, smoking, body mass index, diabetes, blood pressure, lipid levels and statin use.', 'In the crude analyses, energy-adjusted fibre intake showed a significant inverse correlation with IMT (r=-0.27, P<0.001). In multivariate analyses, a modest, though statistically significant (P=0.03) inverse association between energy-adjusted fibre intake and IMT was also found. The multivariate-adjusted difference in average IMT was -0.051 mm (95% confidence interval: -0.094 to-0.009, P=0.02) for participants whose intake was >35 g/day, (n=47) when compared with those whose intake was <25 g/day (n=224).\Question: Is dietary fibre intake inversely associated with carotid intima-media thickness : a cross-sectional assessment in the PREDIMED study?
Our results suggest that high fibre intake is inversely associated with carotid atherosclerosis.
