Type 2 diabetes affects the ability of the body to process glucose (sugar). Under fasting conditions, the liver is able to make sugar to maintain glucose levels in an important process called endogenous glucose production (EGP). Previous studies suggest that the central nervous system (CNS), including the brain, helps to regulate levels of glucose in the body by communicating with the liver. This process can be impaired in people with type 2 diabetes, and can contribute to the high level of glucose seen in these individuals.
The purpose of this study is to understand how activating control centers of the brain with a medication called diazoxide can affect how much glucose (sugar) is made by the liver. This is particularly important for people with diabetes who have very high production of glucose, which in turn can lead to diabetes complications.

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.

Effects of fortified eggs and time-restricted eating on cardiometabolic health: The prosperity trial

Article

BACKGROUND:

Given the increasing interest in dietary interventions to improve cardiovascular health, this trial assessed the impact of fortified eggs (FE) versus nonegg supplemented diet and time-restricted eating (TRE) versus usual care diet on cardiovascular biomarkers.

METHODS:

The study was a unblinded, 2-by-2 factorial design, which randomized patients, with either a prior cardiovascular event or 2 cardiovascular risk factors, to FE or a nonegg supplemented diet and TRE or usual care diet. Patients randomized to FE were instructed to consume at least 12 FE/week (with eggs provided); those on a nonegg supplemented diet restricted egg consumption to <2 eggs/week. TRE participants were instructed to consume all calories within an 8-hour window daily and fasted for the remaining 16 hours. Patients randomized to usual diet were advised to maintain current dietary habits. Follow-up was performed in-person at 1 and 4 months, and telephone calls at 2 and 3 months. Co-primary endpoints were 4-month LDL- and HDL-cholesterol. Secondary endpoints included additional lipids, cardiometabolic- and inflammatory biomarkers and micronutrient levels at 4-months.

RESULTS:

Overall, 140 patients were randomized with median (25th, 75th percentiles) age 66 (58, 73) years; 72 (51%) women, 38 (27%) Black, and 33 (24%) with diabetes mellitus. The difference in least squares (LS) means from baseline to 4-months for HDL and LDL levels revealed no significant clinical difference between FE vs nonegg supplemented diet (HDL: -0.64 mg/dL [95% CI: -3.86, 2.58]; LDL: -3.14 mg/dL [-10.81, 4.52]) and TRE vs usual care diet (HDL: 1.51 mg/dL [-1.65, 4.68]; LDL 1.17 mg/dL [-6.36, 8.70]). Prespecified subgroups revealed a nonsignificant HDL increase and LDL decrease with FE in patients ≥65 years.

CONCLUSIONS:

These data did not demonstrate clinically relevant differences in changes in LDL and HDL levels over 4 months with FE and TRE compared with nonegg supplemented diet and usual care diet, respectively, providing evidence that adverse short-term lipid and biomarker changes did not occur with FE consumption.

“It just made sense to me!” A Qualitative Exploration of Individual Motivation for Time-Restricted Eating

Article

Author: Thompson, Sandra C ; Katzenellenbogen, Judith M ; Rathomi, Hilmi S ; Rathomi, Hilmi S. ; Katzenellenbogen, Judith M. ; Mavaddat, Nahal ; Thompson, Sandra C.

Time-Restricted Eating (TRE), a form of intermittent fasting, has gained popularity for weight control and metabolic health. It is not incorporated into dietary and clinical guidelines, and hence is generally not being recommended to the public. This qualitative study explores how individuals have discovered TRE as a form of dietary practice and their motivations for practising it. Using purposive and snowball sampling, we recruited 21 participants who had engaged in TRE for at least 3 months (range 3 months to over 5 years). In-depth interviews were conducted with an interview guide developed based on the Health Belief Model. We utilised an inductive coding process and thematic analysis to identify the factors motivating TRE adoption. Seven main themes emerged: (1) dissatisfaction and resistance to prior or traditional approaches, (2) perceived broader health benefits, (3) principles of TRE deemed logical, (4) low to no cost of adoption, (5) manageable psychosocial barriers, (6) being non-restrictive and easy to use, and (7) compatibility with personal lifestyle. This study provided insights into early phase of TRE adoption among individuals in real world settings. Future research should explore health practitioners' perspectives on TRE to better understand the acceptability and potential use of TRE as a weight management approach.

Effects of trehalose and sodium alginate on microbially induced carbonate precipitation

Article

Author: Luo, Weijun ; Zhou, Limin ; Zheng, Xiangmin ; Yu, Wenwen ; Zhang, Lidong ; Huang, Xiaowen

The process of altering the microbial-induced carbonate precipitation (MICP) by adding additives has been extensively studied. The impact of polysaccharides, as an important component of bacteria, still requires deeper exploration on MICP. This work thus focuses on two types of sugars, sodium alginate (SA) and trehalose (Tre), to explore their effects on biomineralization of carbonate induced by Bacillus pumilus Z6. The results show that B. pumilus Z6 can raise the environmental pH and increase the supersaturation of carbonate and bicarbonate ions through carbonic anhydrase. The presence of organic functional groups and the negative carbon isotope signatures in minerals provide evidence of microbial involvement. Tre and SA do not change the mineral phase, which mainly consists of hollow rice-like granular vaterite and irregular calcite. Tre is conducive to the formation of calcite, whereas the carboxyl groups in SA contribute to the stability of vaterite. Both Tre and SA enhance the removal rate of calcium ions; however, SA is more effective for this purpose. Furthermore, mineralization experiments with calcium alginate gel tablets indicate that SA can attract calcium carbonate to nucleate on its surface. This research offers significant insights into biomineralization processes and introduces novel perspectives for advancing MICP technology.

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).
