Question: 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.

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

Question: Context: To investigate whether social contact and support received during hospitalization for acute ischemic stroke predict depression and daily life functioning three months later.', 'Prospective observational study using Ecological Momentary Assessments to evaluate the number of social contacts as well as social support received from family, friends and medical staff within 24hours following admission for stroke. Patients also monitored depression symptoms and behavior in real-time and in daily life contexts three months later.', 'A university hospital acute stroke unit.', 'Thirty-four mild ischemic stroke patients.', 'None.', 'One-day Ecological Momentary Assessments immediately following stroke collected information concerning perceived social support, number of social contacts and depression symptoms. Ecological Momentary Assessments was repeated three months later and addressed depression levels as well as activities of daily living, such as working, cooking, shopping and housework.', 'The number of social interactions received at hospitalization did not predict three-month outcomes. However, a better quality of moral support from friends and family immediately after stroke was associated with decreases in later depression levels (p=0.041) and increases in activities of daily living (p=0.011). Material support from friends and family was associated with increases in activities of daily living (p=0.012). No effect was observed for support received from medical staff.
Answer: Patient perceptions of better support quality, and not quantity, immediately following mild stroke, are associated with better behavioral and emotional outcomes three months later.

Answer: Is very early social support following mild stroke associated with emotional and behavioral outcomes three months later?

Question: Context: The value of a new diagnostic test is usually established by analyzing its accuracy in relation to a reference standard. Here we describe a potentially better model of diagnostic research, namely, a diagnostic randomized clinical trial (D-RCT), and discuss its pros and cons using management of critical limb ischemia as an example.', 'Patients clinically suspected of critical limb ischemia are randomized either for the conventional management strategy (treating physician determines the diagnostic and therapeutic strategy on clinical judgment and ankle pressure) or new strategy (transcutaneous oxygen and toe pressure determine the diagnostic and therapeutic strategy). The effect of the diagnostic work-up on the diagnostic and therapeutic process and clinical outcome will be evaluated.', 'A D-RCT is suited when a true reference standard is lacking. It is the best available research method to control for confounding and bias, and it also incorporates the total effect (interpretation and side effects) on clinical outcome. The D-RCT has some disadvantages, however, as to the power and size of the trial and the influence of treatment on the outcome parameter.
Answer: A D-RCT can provide valuable information as to the evaluation of diagnostic tests.

Answer:
Is the diagnostic randomized clinical trial the best solution for management issues in critical limb ischemia?
