ER Niacin/Laropiprant Impact on Cardiovascular Markers and Atheroprogression in HIV-infected Individuals on cART

HIV-infected patients are at increased risk for cardiovascular disease. Large investigations support an inverse correlation between HDL-C levels and coronary heart disease. Therefore a treatment lowering HDL-C such as niacin could reduce the risk of atheroprogression not only through its benefit in terms of lipid profile, but also by reducing atherosclerotic inflammation.
The study aims at showing that a therapy targeting HDL-C increase in HIV-infected patients on suppressive cART has the potential for reducing subclinical atherosclerotic inflammation associated with HIV itself in HIV-individuals on cART.
NILACH is a randomised, multicenter, double blind, placebo controlled, 48 weeks trial to test the effect of the newly marketed niacin/laropiprant on carotid intima-media thickness (IMT) in 90 subjects.
Regimen 1: ER niacin/laropiprant 1g/20 mg for the first 4 weeks and 2g/40mg from week 5 to the end of the study (the titration aims to reduce adverse reactions)
Regimen 2: ER niacin/laropiprant placebo p.m.
The primary end point is the change in mean common carotid intima-media thickness from baseline and 48 weeks, compared between the niacin/laropiprant group and the placebo group.
The proposed in vivo experiments should provide insights on the potential benefits of niacin treatment of cardiovascular disease in HIV patients. In addition, we will be able to further clarify the role of systemic inflammatory mediators in the development of early atherosclerosis of HIV-infected patients on antiretroviral therapy. Detection and treatment of non-infectious co-morbidities such as cardiovascular diseases have become essential for HIV-infected individuals exposed to lifelong antiretroviral therapy and go beyond mere management of opportunistic infections or virologic suppression.

Efficacy of time restricted eating and resistance training on body composition and mood profiles among young adults with overweight/obesity: a randomized controlled trial

Article

Author: Ye, Weibing ; Cui, Tingting ; Liu, Yubo ; Korivi, Mallikarjuna ; Sun, Yichao

BACKGROUND/OBJECTIVE:

Dietary restriction or exercise regimens can promote weight loss or physical fitness among patients with obesity. However, intervention-associated adverse effects may impede patients' motivation to participate in dietary/exercise interventions. We examined the effects of time restricted eating (TRE) with or without resistance training (RT) on body composition, mood profile, and sleep quality in young college adults with overweight or obesity.

METHODS:

Fifty-four young college students with overweight/obesity were randomized into control (CON), TRE, RT, and TRE plus RT (TRE+RT) trials. The TRE trials restricted to an eating window of 10-hour/day for 8-week. The RT trials performed supervised resistance exercise, while the control trial maintained a regular lifestyle. Changes in body composition variables, blood pressure, mood status, and sleep quality were measured before and after the intervention.

RESULTS:

TRE intervention alone or in combination with RT significantly (p < 0.01) decreased body weight (>2 kg) and BMI (~1 kg/m²) in adults with overweight/obesity. Both RT alone and combined with TRE substantially decreased fat mass by 1.1 ± 0.5 and 3.2 ± 0.4 kg, respectively. The decreased fat mass was greater in the combination trial than in the RT trial, whereas TRE alone had no effect. In contrast, fat-free mass was significantly (p < 0.01) decreased with TRE (-2.3 ± 06 kg), increased with RT (1.6 ± 0.3 kg), and was stably maintained with combination interventions. The reduced waist and hip circumferences in the TRE (p < 0.01) were similar to those in the TRE+RT trials, however, RT alone had no effect. Time and group interaction showed a large effect size (partial eta squared) for all body composition variables. In addition, RT with or without TRE notably decreased diastolic blood pressure (RT: -5.5 ± 1.9 mmHg, TRE+RT: -4.1 ± 1.5 mmHg, p < 0.05). Mild anxiety levels at baseline in RT (4.8 ± 2.6) and TRE+RT (4.1 ± 3) trials were found to be normal at postintervention in TRE+RT (3.6 ± 1.7) but not in RT (5.6 ± 3.5). No depression or stress was recorded among the participants during the intervention. The reported poor sleep quality among participants at baseline was significantly improved with RT (4.8 ± 2.9; p < 0.05), and tended to improve with TRE+RT interventions (4.5 ± 1.9).

CONCLUSIONS:

10-hour TRE is beneficial for weight/fat loss without affecting mood status. However, TRE combined with RT might be more effective for weight/fat loss, maintaining muscle mass, and good quality of sleep among young adults with overweight or obesity.

Hypercaloric 16:8 time-restricted eating during 8 weeks of resistance exercise in well-trained men and women

Article

Author: Campidell, Thomas ; Galpin, Andrew J. ; Hamane, Cody ; Tinsley, Grant M. ; Pacheco, Chelscie ; Costa, Pablo ; Blake, Daniel T. ; Coburn, Jared W. ; Henselmans, Menno

BACKGROUND:

The effectiveness and practicality of time-restricted eating (TRE) when trying to maximize muscle mass and strength is unclear. Thus, we examined the effects of a hypercaloric 16:8 TRE approach during supervised progressive resistance exercise.

METHODS:

Seventeen healthy and well-trained men (n = 10) and women (n = 7) were randomly assigned to TRE or control (FED). Both groups consumed a 10% hypercaloric high-protein (2.2 g/kg/d) diet and performed supervised resistance exercise 4× per wk for 8 wk. TRE consumed all calories within an 8 h window starting at least 1 h post-exercise, while FED consumed the same number of calories throughout the day.

RESULTS:

Eating windows were significantly different (TRE: 7.9 ± 0.1 h vs. FED: 13.2 ± 0.6 h). Calorie, carbohydrate, fat, and protein intake did not differ statistically between groups. Total exercise volume was significantly lower in TRE than FED (6,960 ± 287 vs. 7,334 ± 289 repetitions), as were subjective daily energy ratings (week 4 = -1.41; p = 0.04, week 8 = -1.04; p = 0.06). Both groups increased maximal upper and lower body strength (1RM) and muscular endurance (ME); however, gains in squat 1RM were 4.0 ± 1.9 kg lower in TRE (p = 0.05). Both groups increased fat-free mass similarly (TRE: 2.67 kg; FED: 1.82 kg, p = 0.04), but FED added 1.4 ± 0.6 kg more fat mass (p = 0.04). Subjective mood and sleep ratings did not change in either group.

CONCLUSIONS:

16:8 TRE is viable during periods of muscle size, strength, and endurance development in well-trained young men and women when engaging in progressive resistance exercise and eating in a caloric surplus with adequate protein. However, the differences in total training volume, squat 1RM, fat mass accumulation, and energy are notable and practically relevant. These findings should be considered within the broader context of an individual's goals, lifestyle, preferences, and exercise demands.

Effectiveness of 8-hour time-restricted eating combined with different dietary patterns on body composition, lipid metabolism, and oxidative stress in healthy adults: An exploratory study from an RCT

Article

Author: Liu, Jixiang ; Yao, Shukun ; Li, Kaimin ; Kong, Youjia ; Zhou, Yuanchen ; Liang, Xinzheng ; Xue, Lijun

OBJECTIVES:

To evaluate the effectiveness of a 4-week intervention of time-restricted eating (TRE) alone or in combination with an elimination of ultra-processed foods or vegetarian diet, on body composition, lipid metabolism, and oxidative stress.

METHODS:

This was a randomized controlled trial including 70 participants comparing three diet groups maintained for a 4-week period: A, TRE alone; B, TRE with elimination of ultra-processed foods; and C, TRE with a vegetarian diet. Per-protocol analyses of body composition, plasma lipid levels, and oxidative stress markers were performed.

RESULTS:

Compared to baseline, Group B significantly reduced weight (P = 0.02), body mass index, waist and hip circumference, as well as fat ratio, total cholesterol, 4-hydroxynonenal an 8-Iso prostaglandin F 2α (all P < 0.05). Group B also increased high-density lipoprotein cholesterol (P < 0.05) and catalase (P = 0.002). Compared to Group A, Group B was more effective in decreasing body mass index (Δ: -0.1 ± 0.7 vs. -0.2 ± 0.3, respectively, P = 0.041) and waist circumference (Δ: -1.1 ± 4.0 vs. -3.5 ± 4.4, P < 0.001). Compared to Group A and B, the increase in superoxide dismutase (Δ: 12.74 ± 8.34, P < 0.05) and glutathione (Δ: 0.63 ± 0.40, P < 0.05) was significantly greater for Group C. Group C also produced a greater decrease in malondialdehyde (Δ: -0.79 ± 0.28) than the Group A (Δ: -0.32 ± 0.51, P < 0.001) and Group B (Δ: -0.20 ± 0.68, P < 0.001) diets.

CONCLUSIONS:

Consumption of ultra-processed foods can increase body composition and lipid profile, despite TRE. A vegetarian diet in combination with TRE is effective in reducing oxidative stress injury.

FDA sends warning letter to Merck & Co over vaccines plant

Merck & Co’s week of woe has continued with the news that US regulators have told the firm to correct what are described as “numerous manufacturing deficiencies” at its main vaccines plant. The US Food and Drug Administration has issued a warning letter to Merck having conducted an inspection of the firm’s West Point, Pennsylvania facility between November 26, 2007 and January 17 this year. The agency’s investigators say they documented “significant deviations from current good manufacturing practice” at the plant in the manufacture of vaccine products, bulk drug substances and drug components. The products manufactured at the West Point site include Merck & Co’s cervical cancer vaccine Gardasil and ProQuad, its combination jab against measles, mumps, rubella and chicken pox. Also produced at the facility are the Haemophilus influenzae type B vaccine PedvaxHIB and ComVax for haemophilius b and hepatitis B and 1.2 million doses of these two jabs were voluntarily recalled in December because Merck said it could not assure sterility of those specific vaccine lots. The warning letter, which is posted on the FDA’s website in a heavily edited form, has been issued because Merck's response to the FDA’s initial inspection report was "inadequate to address the serious deviations noted”. Most of the myriad complaints appear to deal with procedural errors but the agency stresses it "does not believe that the issues identified will affect the safety of the vaccines" made at the facility. Merck says that it is committed to working with the FDA to address these issues, adding that it does not distribute contaminated products and is confident in their “quality, effectiveness and safety”. The letter comes in a week when Merck’s stock has taken a bashing after the FDA rejected applications firstly for a proposed fixed combination of Singulair (montelukast) and S-P’s Claritin (loratadine) as a treatment for allergic rhinitis and secondly for its new cholesterol compound MK-0524A (extended-release niacin/laropiprant).
