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.

Q: Context: Evidence of attack-related cognitive dysfunction in migraine is growing. Controversy exists on whether cognitive dysfunction, mainly executive, may persist between attacks. Measuring the impact of cognitive function is gaining importance in clinical and research settings in migraine.', 'To compare the performance of interictal migraine patients to controls in an assembled neuropsychological battery focused on executive functions and to study the practice effect of its repeated applications.', 'Assembly of the battery that was then applied twice within 6\xa0weeks to interictal migraineurs and matched healthy controls.', 'Migraine patients (n\xa0=\xa024) and controls (n\xa0=\xa024) had similar performance in both applications of the battery. There was a slight practice effect between the first and second evaluation, significant in Stroop Interference test (P\xa0=\xa00.002, multiplicity corrected); a meaningful score change was determined for each raw test scores.\Question: Is sequential brief neuropsychological evaluation of migraineurs identical to controls?

A: Interictal migraineurs and controls performance is identical in a brief cognitive battery focused on executive functions. Repeated applications produced a practice effect that was quantified.

Q: Context: Poor condition at operation determined by the physiologic POSSUM score is related to postoperative mortality and morbidity of colorectal cancer surgery. This study was designed to analyze the relationship between condition of patients with colorectal cancer at operation and long-term overall survival.', 'A total of 542 patients survived a radical resection for Stages I, II, or III colorectal cancer. Physiologic POSSUM score at surgery, exclusive of age, was calculated for all patients. Mean physiologic POSSUM score was used as cutoff point to determine low-risk and high-risk group patients. A Cox proportional hazard analysis was performed to study the effect of low-risk and high-risk group on overall survival and to identify independent risk factors.', 'Five-year overall survival was significantly higher in low-risk group patients than in high-risk group patients (low-risk group 66.6 percent vs. high-risk group 48.5 percent; P < 0.001). Differences in overall survival also were found when patients in Stages I, II, and III were analyzed separately. Risk factors for overall survival were advanced stage of disease, poor tumor differentiation, mucinous adenocarcinoma, older than age 70 years, and poor condition of the patient at time of operation.\Question: Does pOSSUM predict decreased overall survival in curative resection for colorectal cancer?

A: Poor condition at operation, as determined by physiologic POSSUM score, is a risk indicator for long-term overall survival in colorectal cancer patients.

Q: Context: The modulation of intracortical inhibition is thought to be impaired in older adults, which may contribute to their reduced fine motor control, particularly during lengthening muscle contractions.', 'To quantify the magnitude of intracortical inhibition and movement performance during postural, shortening and lengthening contractions of a hand muscle in young and old adults.', 'In 18 young (23.2 ± 4.2) and 16 old (70.6 ± 6.5) subjects, paired-pulse transcranial magnetic stimulation (TMS) was used to assess short-interval intracortical inhibition (SICI) and long-interval intracortical inhibition (LICI) during a movement task involving the first dorsal interosseous muscle. The task required a constant load (50 g) to be slowly lifted and lowered using the index finger while single- or paired-pulse TMS was delivered during the shortening or lengthening contraction.', 'Relative to postural contractions, SICI during shortening contractions was reduced by 29% in young subjects (P < 0.0001) and 43% in old subjects (P < 0.0001), whereas SICI during lengthening contractions was reduced by 11% in young subjects (P = 0.0004) and 33% in old subjects (P < 0.0001). Furthermore, SICI was significantly less in older adults during lengthening contractions (P-values < 0.01). For LICI, inhibition was not influenced by contraction type in old subjects, but was increased by 11% during shortening contractions (P < 0.0001) and by 9% during lengthening contractions in young subjects (P = 0.0008). In addition, old subjects showed significantly less LICI than young subjects in each movement phase (both P-values < 0.05).\Question: Is intracortical Inhibition Assessed with Paired-Pulse Transcranial Magnetic Stimulation Modulated during Shortening and Lengthening Contractions in Young and Old Adults?

A:
Shortening and lengthening contractions with a constant load are associated with a modulation of GABAergic inhibition that is altered by healthy ageing.
