Input: Consider Input: Context: Asteatotic eczema (AE) is characterized by itchy, dry, rough, and scaling skin. The treatments for AE are mainly emollients, usually containing urea, lactic acid, or a lactate salt. N-palmitoylethanolamine (PEA) and N-acetylethanolamine (AEA) are both endogenous lipids used as novel therapeutic tools in the treatment of many skin diseases. The purpose of this study was to compare a PEA/AEA emollient with a traditional emollient in the treatment of AE.', "A monocentric, randomized, double-blind, comparative trial was conducted in 60 AE patients to evaluate and compare the efficacy of the two emollients. The level of skin dryness among the subjects ranged from mild to moderate. The subjects' skin barrier function and the current perception threshold were tested for 28 days by clinical scoring and bioengineering technology.", 'The results showed that, although some aspects were improved in both groups, the group using the emollient containing PEA/AEA presented a better skin surface change in capacitance. However, the most impressive finding was the ability of the PEA/AEA emollient to increase the 5 Hz current perception threshold to a normal level after 7 days, with a significant difference between values at baseline and after 14 days. A current perception threshold of 5 Hz was positively and significantly correlated with skin surface hydration and negatively correlated with transepidermal water loss in the PEA/AEA emollient group.
Answer: Compared with traditional emollients, regular application of a topical PEA/AEA emollient could improve both passive and active skin functions simultaneously.

Output: Are n-palmitoylethanolamine and N-acetylethanolamine effective in asteatotic eczema : results of a randomized , double-blind , controlled study in 60 patients?


Input: Consider Input: Context: What are typical values of physical function for women diagnosed with breast cancer and how do these compare to normative data?', 'Systematic review with meta-analysis.', 'Women diagnosed with breast cancer who were before, during or after treatment.', 'Physical function was divided into three categories: aerobic capacity, upper and lower extremity muscular fitness, and mobility. Measures of aerobic capacity included field tests (6-minute walk test, 12-minute walk tests, Rockport 1-mile test, and 2-km walk time) and submaximal/maximal exercise tests on a treadmill or cycle ergometer. Measures of upper and lower extremity muscular fitness included grip strength, one repetition maximum (bench, chest or leg press), muscle endurance tests, and chair stands. The only measure of mobility was the Timed Up and Go test.', 'Of the 1978 studies identified, 85 were eligible for inclusion. Wide ranges of values were reported, reflecting the range of ages, disease severity, treatment type and time since treatment of participants. Aerobic fitness values were generally below average, although 6-minute walk time was closer to population norms. Upper and lower extremity strength was lower than population norms for women who were currently receiving cancer treatment. Lower extremity strength was above population norms for women who had completed treatment.
Answer: Aerobic capacity and upper extremity strength in women diagnosed with breast cancer are generally lower than population norms. Assessment of values for lower extremity strength is less conclusive. As more research is published, expected values for sub-groups by age, treatment, and co-morbidities should be developed. [Neil-Sztramko SE, Kirkham AA, Hung SH, Niksirat N, Nishikawa K Campbell KL (2014) Aerobic capacity and upper limb strength are reduced in women diagnosed with breast cancer: a systematic review.Journal of Physiotherapy60: 189-200].

Output: Are aerobic capacity and upper limb strength reduced in women diagnosed with breast cancer : a systematic review?


Input: Consider Input: Context: T2 Lesion Volume (T2LV) has been an important biomarker for multiple sclerosis (MS). Current methods available to quantify lesions from MR images generally require manual adjustments or multiple images with different contrasts. Further, implementations are often not easily or openly accessible.', 'We created a fully unsupervised, single T2 FLAIR image T2LV quantification package based on the popular open-source imaging toolkit FSL.', 'By scripting various processing tools in FSL, we developed an image processing pipeline that distinguishes normal brain tissue from CSF and lesions. We validated our method by hierarchical multiple regression (HMR) with a preliminary study to see if our T2LVs correlate with clinical disability measures in MS when controlled for other variables.', 'Pearson correlations between T2LV and Expanded Disability Status Scale (EDSS: r = 0.344, P = 0.013), Six-Minute Walk (6MW: r = -0.513, P = 0.000), Timed 25-Foot Walk (T25FW: r = -0.438, P = .000), and Symbol Digit Modalities Test (SDMT: r = -0.499, P = 0.000) were all significant. Partial correlations controlling for age were significant between T2LV and 6MW (r = -0.433, P = 0.002), T25FW (r = -0.392, P = 0.004), and SDMT (r = -0.450, P = 0.001). In HMR, T2LV explained significant additional variance in 6MW (R(2) change = 0.082, P = 0.020), after controlling for confounding variables such as age, white matter volume (WMV), and gray matter volume (GMV).
Answer: Our T2LV quantification software produces T2LVs from a single FLAIR image that correlate with physical disability in MS and is freely available as open-source software.


Output: Does fully automated open-source lesion mapping of T2-FLAIR images with FSL correlate with clinical disability in MS?
