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: To assess the influence of moderate, acute weight loss on on-water rowing performance when aggressive nutritional recovery strategies were used in the two hours between weigh in and racing.', 'Competitive rowers (n = 17) undertook three on-water 1800 m time trials under cool conditions (mean (SD) temperature 8.4 (2.0) degrees C), each separated by 48 hours. No weight limit was imposed for the first time trial--that is, unrestricted body mass (UNR1). However, one of the remaining two trials followed a 4% loss in body mass in the previous 24 hours (WT(-4%)). No weight limit was imposed for the other trial (UNR2). Aggressive nutritional recovery strategies (WT(-4%), 2.3 g/kg carbohydrate, 34 mg/kg Na+, and 28.4 ml/kg fluid; UNR, ad libitum) were used in the first 90 minutes of the two hours between weigh in and performance trials.', 'WT(-4%) had only a small and statistically non-significant effect on the on-water time trial performance (mean 1.0 second, 95% confidence interval (CI) -0.9 to 2.8; p = 0.29) compared with UNR. This was despite a significant decrease in plasma volume at the time of weigh in for WT(-4%) compared with UNR (-9.2%, 95% CI -12.8% to -5.6%; p<0.001).\Question: Does acute weight loss followed by an aggressive nutritional recovery strategy have little impact on on-water rowing performance?
[A]: Acute weight loss of up to 4% over 24 hours, when combined with aggressive nutritional recovery strategies, can be undertaken with minimal impact on on-water rowing performance, at least in cool conditions.


[Q]: Context: Dynamic pelvic magnetic resonance imaging (DP-MRI) offers a comprehensive evaluation of pelvic organ structure in addition to functional information regarding evacuation. Opportunity to apply this technology can be limited due to regional lack of availability. Ideally, clues from standard anorectal testing could predict abnormalities on DP-MRI, leading to its efficient use. The aim of this study is to determine whether high-resolution anorectal manometry (HR-ARM) correlates with findings on DP-MRI.', "This is a retrospective study of HR-ARM performed on patients with constipation who also underwent DP-MRI. Studies were reviewed for significant findings including posterior pelvic organ prolapse, rectocele\u2009>\u20093\u2009cm, rectal intussusception, and anorectal angle. Statistical analysis was performed using Pearson's correlation coefficient, Student's t-test, and Fisher's exact test.", 'Twenty-three patients undergoing HR-ARM (age range 25-78) also underwent DP-MRI. All were female; 76% were Caucasian. Twenty had significant structural findings: small pelvic prolapse (n\u2009=\u20092), moderate pelvic prolapse (n\u2009=\u200910), large pelvic prolapse (n\u2009=\u20099), rectocele (n\u2009=\u20098), or rectal intussusception (n\u2009=\u20093). Only intrarectal pressure on HR-ARM weakly correlated with size of rectocele (r\u2009=\u20090.46; P\u2009=\u20090.03) and degree of pelvic organ prolapse (r\u2009=\u20090.48; P\u2009=\u20090.02). The remainder of the HR-ARM parameters did not significantly correlate with DP-MRI findings. Patients with dyssynergy were not more likely to have rectoceles\u2009>\u20093\u2009cm (44.4% versus 35.7%; P\u2009=\u20090.5) or large prolapses (44.4% versus 50%, P\u2009=\u20091.0), compared with those without dyssynergy, on HR-ARM.\Question: Are high-resolution anorectal manometry and dynamic pelvic magnetic resonance imaging complementary technologies?
[A]: We were unable to find a correlation between HR-ARM findings and structural pelvic defects on DP-MRI. Therefore, these two technologies provide complementary information in the evaluation of defecatory dysfunction.


[Q]: Context: Statins have been proposed as a potential treatment for systemic lupus erythematosus (SLE) due to their immunomodulatory properties, their role restoring endothelial function and preventing atherosclerosis. We evaluate the effect of a short period treatment with a low dose of atorvastatin and its withdrawal on early stage subclinical atherosclerosis.', 'Thirty-seven SLE females received 20\u2009mg/day atorvastatin during eight weeks. At baseline, at the end of treatment and six months after atorvastatin withdrawal, disease activity, subclinical atherosclerosis -assessed by measuring carotid-femoral pulse wave velocity (PWV) - and quantification of circulating endothelial progenitor cells (EPC) - as a surrogate biological marker of subclinical atherosclerosis - were carried out.', 'The group of SLE patients with baseline pathological arterial stiffness showed a significant decrease of PWV after atorvastatin therapy (8.43\u2009±\u20091.45\u2009m/s vs 7.42\u2009±\u20091.06\u2009m/s; p\u2009=\u20090.002) that is maintained six months after treatment finished. Only patients of the middle-aged group showed a nearly significant decrease in the PWV measured along the study (7.16\u2009±\u20091.23\u2009m/s vs 6.76\u2009±\u20090.82\u2009m/s; p\u2009=\u20090.05). Atorvastatin induced a significant decrease in the circulating EPC percentage (0.65\u2009±\u20090.67 vs 0.40\u2009±\u20090.31; p\u2009=\u20090.023) as well as a downward trend of disease activity that it is observed by a decrease in SLE disease activity index simultaneously with an increase in C3 complement and significant decrease in serum concentration of vascular endothelial grow factor (VEGF) and sVCAM-1.\Question: Does short-term atorvastatin therapy improve arterial stiffness of middle-aged systemic lupus erythematosus patients with pathological pulse wave velocity?
[A]:
Short-term atorvastatin therapy reduces arterial stiffness of SLE patients with baseline pathological PWV, who are mainly in the group of middle-aged patients. Further studies are needed to determine whether these patients would benefit from statin therapy in preventing cardiovascular events.
