Economic evaluation of a weight control program with e-mail and telephone counseling among overweight employees: a randomized controlled trial
<p>Abstract</p> <p>Background</p> <p>Distance lifestyle counseling for weight control is a promising public health intervention in the work setting. Information about the cost-effectiveness of such interventions is lacking, but necessary to make informed implementation decisions. The purpose of this study was to perform an economic evaluation of a six-month program with lifestyle counseling aimed at weight reduction in an overweight working population with a two-year time horizon from a societal perspective.</p> <p>Methods</p> <p>A randomized controlled trial comparing a program with two modes of intervention delivery against self-help. 1386 Employees from seven companies participated (67% male, mean age 43 (SD 8.6) years, mean BMI 29.6 (SD 3.5) kg/m<sup>2</sup>). All groups received self-directed lifestyle brochures. The two intervention groups additionally received a workbook-based program with phone counseling (phone; n=462) or a web-based program with e-mail counseling (internet; n=464). Body weight was measured at baseline and 24 months after baseline. Quality of life (EuroQol-5D) was assessed at baseline, 6, 12, 18 and 24 months after baseline. Resource use was measured with six-monthly diaries and valued with Dutch standard costs. Missing data were multiply imputed. Uncertainty around differences in costs and incremental cost-effectiveness ratios was estimated by applying non-parametric bootstrapping techniques and graphically plotting the results in cost-effectiveness planes and cost-effectiveness acceptability curves.</p> <p>Results</p> <p>At two years the incremental cost-effectiveness ratio was €1009/kg weight loss in the phone group and €16/kg weight loss in the internet group. The cost-utility analysis resulted in €245,243/quality adjusted life year (QALY) and €1337/QALY, respectively. The results from a complete-case analysis were slightly more favorable. However, there was considerable uncertainty around all outcomes.</p> <p>Conclusions</p> <p>Neither intervention mode was proven to be cost-effective compared to self-help.</p> <p>Trial registration</p> <p>ISRCTN04265725</p

Oleic acid triggers metabolic rewiring of T cells poising them for T helper 9 differentiation
T cells are the most common immune cells in atherosclerotic plaques, and the function of T cells can be altered by fatty acids. Here, we show that pre-exposure of CD4+ T cells to oleic acid, an abundant fatty acid linked to cardiovascular events, upregulates core metabolic pathways and promotes differentiation into interleukin-9 (IL-9)-producing cells upon activation. RNA sequencing of non-activated T cells reveals that oleic acid upregulates genes encoding key enzymes responsible for cholesterol and fatty acid biosynthesis. Transcription footprint analysis links these expression changes to the differentiation toward TH9 cells, a pro-atherogenic subset. Spectral flow cytometry shows that pre-exposure to oleic acid results in a skew toward IL-9+-producing T cells upon activation. Importantly, pharmacological inhibition of either cholesterol or fatty acid biosynthesis abolishes this effect, suggesting a beneficial role for statins beyond cholesterol lowering. Taken together, oleic acid may affect inflammatory diseases like atherosclerosis by rewiring T cell metabolism.</p
Increased Mortality in SDHB but Not in SDHD Pathogenic Variant Carriers
Germline mutations in succinate dehydrogenase subunit B and D (SDHB and SDHD) are
predisposed to hereditary paraganglioma (PGL) and pheochromocytoma (PHEO). The phenotype of
pathogenic variants varies according to the causative gene. In this retrospective study, we estimate
the mortality of a nationwide cohort of SDHB variant carriers and that of a large cohort of SDHD
variant carriers and compare it to the mortality of a matched cohort of the general Dutch population.
A total of 192 SDHB variant carriers and 232 SDHD variant carriers were included in this study.
The Standard Mortality Ratio (SMR) for SDHB mutation carriers was 1.89, increasing to 2.88 in carriers
affected by PGL. For SDHD variant carriers the SMR was 0.93 and 1.06 in affected carriers. Compared
to the general population, mortality seems to be increased in SDHB variant carriers, especially in
those affected by PGL. In SDHD variant carriers, the mortality is comparable to that of the general Dutch population, even if they are affected by PGL. This insight emphasizes the significance of
DNA-testing in all PGL and PHEO patients, since different clinical risks may warrant gene-specific
management strategies
