The RELAX randomized controlled trial: Stretching versus meditation for nocturnal muscle cramps.

BACKGROUND: Muscle cramps are common among persons with cirrhosis and are associated with poor health-related quality of life (HRQOL). Treatment options are limited. We compared stretching or meditation in a randomized-controlled trial (RCT). PATIENTS: We enrolled 98 patients with a history of >4 muscle cramps in the prior month from 7/22-7/23. We randomized patients 1:1 to stretching versus meditation for 35 days. Our primary outcome was the change in cramp severity measured by the visual analogue scale for cramps (VAS-cramps, scaled 0-10). Secondary outcomes included a patient global impression of change (PGIC), change in sleep quality and global HRQOL measured using the EQ-5D and VAS-global HRQOL. RESULTS: Overall, 48% of patients had cirrhosis, 40% had diabetes, 16% the median age was 63, most were women (67%) and 81% were college educated. Both arms experienced a reduction in cramp severity-a median of 1.44 (.58-2.29) points for stretching and 1.97 (1.01-2.93) points for meditation. These changes were significant changes from baseline (p = .001 for stretching, p < .0001 for meditation) but these changes were equivalent between arms (p = .4). The PGIC was improved: 1.33 (1.02-1.65) for stretching, 1.05 (.70-1.41) for meditation, p-difference .2. Sleep was also improved for both. HRQOL did not change according to the Eq5D; according to the VAS, HRQOL rose for meditation by 6 (.1-11.8) points but not for stretching. More patients recommended stretching than meditation (79.2% vs. 55.3%, p = .02). CONCLUSION: In a randomized trial, stretching and meditation both reduced cramp severity and improved sleep quality and global impression of change. While patients preferred stretching, there was no difference in effect between arms.

Lactulose therapy for patients with cirrhosis, portal hypertension, and poor patient-reported outcomes: The Mi-Kristal trial.

BACKGROUND AND AIMS: Poor patient-reported outcomes (PROs) are common in cirrhosis, including poor sleep and health-related quality of life (HRQOL). HE is a major driver of poor PROs. Many clinicians initiate lactulose therapy to address poor PROs. PRO-triggered therapy, however, has not been studied till date. METHODS: We conducted a 28-day randomized trial of crystalline lactulose therapy (20 g BID) compared with no HE-directed therapy in 52 patients with cirrhosis, portal hypertension, no prior HE, and high Work Productivity and Activity Impairment scores (0-10) attributed to cirrhosis. The primary outcome was change in global HRQOL measured with Short Form-8 Health Survey. Secondary outcomes included change in Animal Naming Test score, Work Productivity and Activity Impairment, and sleep quality (scored "very bad" to "very good"). APPROACH AND RESULTS: Overall, 52 patients underwent randomization; 3 subjects withdrew from the crystalline lactulose arm (1 before medication initiation, 1 due to an unrelated condition, and 1 due to high baseline bowel movements). The average age was 60 years, the average Model for Endstage Liver Disease-Sodium score was 10.5, and 56% of the patients had ascites. Baseline bowel movements were 2.3/day, with 35% of the patients having Bristol Stool Scale >4. At 28 days, there was no improvement in HRQOL: patients receiving crystalline lactulose had an 8.1-point (95% CI: 3.7-12.4) increase compared with 6.6 (95% CI: 2.3-10.8) in the control group ( p = 0.6). Lactulose was associated with a significantly ( p = 0.002) increased Animal Naming Test score (3.7, 95% CI: 2.1-5.4) versus the control group (0.2, 95% CI: -1.7, 1.4). Lactulose users reported more good sleep (92% vs. 52%, p = 0.001) and lower activity impairment (3.0 vs. 4.8, p = 0.02). CONCLUSIONS: Lactulose improves sleep and activity impairment in patients with poor PROs. We did not observe any improvement in global HRQOL after 28 days using the Short Form-8 Health Survey instrument.

Fructose Protects Against Acetaminophen-Induced Hepatotoxicity Mainly by Activating the Carbohydrate-Response Element-Binding Protein α-Fibroblast Growth Factor 21 Axis in Mice.

Acetaminophen (N-acetyl-para-aminophenol [APAP]) overdose is the most common cause of drug-induced liver injury in the Western world and has limited therapeutic options. As an important dietary component intake, fructose is mainly metabolized in liver, but its impact on APAP-induced liver injury is not well established. We aimed to examine whether fructose supplementation could protect against APAP-induced hepatotoxicity and to determine potential fructose-sensitive intracellular mediators. We found that both high-fructose diet feeding before APAP injection and fructose gavage after APAP injection reduced APAP-induced liver injury with a concomitant induction of the hepatic carbohydrate-response element-binding protein α (ChREBPα)-fibroblast growth factor 21 (FGF21) pathway. In contrast, Chrebpα liver-specific-knockout (Chrebpα-LKO) mice failed to respond to fructose following APAP overdose, suggesting that ChREBPα is the essential intracellular mediator of fructose-induced hepatoprotective action. Primary mouse hepatocytes with deletion of Fgf21 also failed to show fructose protection against APAP hepatotoxicity. Furthermore, overexpression of FGF21 in the liver was sufficient to reverse liver toxicity in APAP-injected Chrebpα-LKO mice. Conclusion: Fructose protects against APAP-induced hepatotoxicity likely through its ability to activate the hepatocyte ChREBPα-FGF21 axis.
